Embodiment
For making that architectural feature of the present utility model and effect of reaching are had a better understanding and awareness, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As depicted in figs. 1 and 2; a kind of protection of the breaking line preventive for 10kV and following overhead transmission line prior-warning device described in the utility model; comprise left concrete bar 7 and right concrete bar 8; on left concrete bar 7, left horizontal stretcher 11 is installed; on right concrete bar 8, right horizontal stretcher 12 is installed, transmission line 1 is arranged between left horizontal stretcher 11 and right horizontal stretcher 12 in the mode of prior art.In order to prevent that transmission line from being set or bamboo breaks, comprise left involutory anchor ear 13 and right involutory anchor ear 3.Left involutory anchor ear 13 is arranged on left concrete bar 7 and is positioned at left horizontal stretcher 11 800mm places, top, right involutory anchor ear 3 is arranged on right concrete bar 8 and is positioned at right horizontal stretcher 12 800mm places, top, thereby fix steel hinge line 6 and be arranged on transmission line 1 800mm place, top, ensured the routine use safety of transmission line 1.On left involutory anchor ear 13, be provided with in bracing wire 4, lower 5 of bracing wire be installed on right involutory anchor ear 3, in bracing wire 4 with lower 5 of bracing wire for being connected steel hinge line 6, in use prior art, various ways is arranged on left involutory anchor ear 13 and right involutory anchor ear 3.In bracing wire 4 and lower 5 of bracing wire between steel hinge line 6 is installed; in the time of winter snows season, tree is by under crushing by snow time; 6 gears of steel hinge line are above transmission line 1; avoid transmission line 1 to be broken by tree; simultaneously in the sleet time; steel hinge line 6 can replace transmission line 1 to bear most sleet, has also protected transmission line 1.In order to report to the police when larger at steel hinge line 6 pressurizeds, steel hinge line 6 is passed from precaution device 2, by precaution device 2, steel hinge line 6 pressurized situations are reported to the police.Determine according to on-site actual situations the position of precaution device 2 on steel hinge line 6, can middle, also can be at the two ends of steel hinge line 6, ideal effect be branch while pressing down precaution device 2 can directly be crushed under branch, thereby branch drives precaution device 2 to press down to pull steel hinge line 6 and triggers loudspeaker 26 like this.
As shown in Figure 3, precaution device 2 comprises shell 20, and the left side of shell 20 and right side have 21He You hole, left hole 22, and 21He You hole 22, left hole is passed for steel hinge line 6.The position parallel aligned in 21Yu You hole, left hole 22, steel hinge line 6 does not change in relative altitude in the time penetrating precaution device 2 and while passing precaution device 2.Top in shell 20 is installed with extension spring 30, and extension spring 30 belows are provided with draw ring 29, draw ring 29 for steel hinge line 6 in precaution device 2 through fixing.The position of draw ring 29 is higher than 21He You hole, left hole 22, and draw ring 29,21He You hole, left hole 22 form a leg-of-mutton structure.Steel hinge line 6 passes successively from left hole 21, draw ring 29 and right hole 22, and steel hinge line 6 has formed the version that is equivalent to triangle waist on precaution device 2.Bottom in shell 20 is provided with cushion cap 23, and cushion cap 23, for placing lower conducting strip A24 and lower conducting strip B25, is provided with lower conducting strip A24 and lower conducting strip B25 on cushion cap 23, and lower conducting strip A24 does not contact with lower conducting strip B25.Lower conducting strip A24 connects successively loudspeaker 26, battery 27 and lower conducting strip B25 by electric wire and forms warning circuit, if by lower conducting strip A24 and lower conducting strip B25 conducting, can form a series loop, loudspeaker 26 are reported to the police.Upper conducting strip 28, lower conducting strip A24 and lower conducting strip B25 can be copper sheet, realize conducting function.Draw ring is installed with conducting strip 28 29 times, lower conducting strip A24 and lower conducting strip B25 are positioned at the below of conducting strip 28 and fell to 23 of cushion caps when upper when upper conducting strip 28, lower conducting strip A24, lower conducting strip B25 and upper conducting strip 28 three's overlap joints, warning circuit conducting.Upper conducting strip 28 can touch lower conducting strip A24 and lower conducting strip B25 while moving downward, thereby by lower conducting strip A24 and lower conducting strip B25 conducting.
In order to increase pressure-bearing property and the stability of steel hinge line 6, can also comprise Zola's line 9 and right bracing wire 10, Zola's line 9 is arranged on left involutory anchor ear 13, and right bracing wire 10 is arranged on right involutory anchor ear 3.The other end fixed installation of Zola's line 9 and right bracing wire 10, in the time that steel hinge line 6 is stressed, Zola's line 9 and right bracing wire 10 can increase the stability of steel hinge line 6 like this.As shown in Figure 2, better for fixed effect, Zola's line 9 oblique pulls are on the involutory anchor ear 13 in a left side, and right bracing wire 10 oblique pulls are on the involutory anchor ear 3 in the right side.Oblique pull angle can be 90 degree, the stayguy direction that is Zola's line 9 can be perpendicular with steel hinge line 6, the stayguy direction of right bracing wire 10 and steel hinge line 6 are perpendicular, can oppositely apply pulling force with mutual balance at concrete bar like this in the time that steel hinge line 6 is subject to direction pulling force that top brings when pressure.
In the time that reality is used, when in the extreme weather such as heavy snow, strong wind situation, branch tilts to press down.The steel hinge line 6 of installing on transmission line keeps off on transmission line 1, has avoided transmission line 1 to be tilted to break by branch.In the time that branch tilts to reach certain pressure, the pressure bearing on steel hinge line 6 increases, and steel hinge line 6 presses down.While passing precaution device 2 due to steel hinge line 6, form triangular structure by draw ring 29,21He You hole, left hole 22, in the time that precaution device 2 is pressed down or steel hinge line 6 is subject to pressing down, steel hinge line 6 has redundancy in precaution device 2, position-limiting action has been played to steel hinge line 6 in 21He You hole 22, left hole, has driven steel hinge line 6 entirety in precaution device 2 to press down.Be that precaution device 2 can be along with steel hinge line 6 presses down, but the effect that steel hinge line 6 pulls draw ring 29 to overcome extension spring 30 from 21He You hole, left hole 22 respectively moves downward, move downward and finally touch lower conducting strip A24 and lower conducting strip B25 thereby form upper conducting strip 28 downwards.As shown in Figure 4, in the time that upper conducting strip 28 contacts with lower conducting strip A24, lower conducting strip B25, form a series loop, loudspeaker 26 work are reported to the police.Different with the environment that passes through the woods according to the overhead transmission line of different brackets, can the warning in different pressures situation be set for precaution device 2, only need to adjust the pulling force of extension spring 30 or adjust the distance between upper conducting strip 28 and lower conducting strip A24, lower conducting strip B25, the distance in adjustment between conducting strip 28 and lower conducting strip A24, lower conducting strip B25 can realize by increasing length between upper conducting strip 28 and draw ring 29 or the height of increase cushion cap 23.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
