Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
As shown in Figure 1, a kind of deep water negative pressure desilting system of the present invention, comprising: a desilting pipe 11, and described desilting pipe 11 is arranged in water, and its top is connected with output channel 12, and its bottom is arranged in water to treat desilting position; One air-supply duct 13, described air-supply duct 13 is installed on desilting pipe 11 side, the top of air-supply duct 13 is connected with air compressor machine (not shown) by airduct 14, and its bottom is provided with the inflator 15 being connected with air-supply duct 13, and described inflator 15 is connected with desilting pipe 11. When reality uses, the output terminal of output channel 12 is arranged at settling bowl (not shown) and carries out subsequent disposal, avoids polluting.
In the present embodiment, described output channel 12 adopts plastics tubing. Being further plastic hose, can be applicable to various environment, as being layed in the uneven ground of height, described plastic hose refers to fit in the tubing on ground; When there is gaseous tension in plastic hose, being beneficial to air pressure and promoting mud to move, and then reaching the object improving desilting efficiency data.
In the present embodiment, described desilting pipe 11 comprises pipe body, in inverted cone shape bottom pipe body, is provided with end mouth 111 and end mouth 111 place is provided with filtering net (not shown) bottom pipe body. Further, described filtering net becomes by some the crisscross settings of reinforcing bar bar and the spacing of adjacent reinforcing bar bar is less than 150mm. Therefore in the present embodiment, the conveying particle diameter of described filtering net is the sandstone being less than 150mm. In the present embodiment, described desilting pipe 11 erects to setting.
Wherein, described pipe body is set to some, and adjacent pipe body is connected by flange (not shown); The waters 17 that so can be applicable to different depths, adaptable, and easy to operate. The length of described pipe body is less than 6m, and its diameter is 273mm.
As shown in Figure 2, in the present embodiment, described inflator 15 is annular canister, and is sheathed on the outside of desilting pipe 11, and the diameter that the tube wall that described inflator 15 is connected with desilting pipe 11 is equipped with connection is the inlet mouth 151 of 10mm. Wherein, described inflator 15 is arranged with desilting pipe 11 is concentric; Wherein, it is arranged at the distance bottom the enterprising gas port of desilting pipe 11 and inflator 15 and it is greater than the distance being arranged at bottom the enterprising gas port of inflator 15 and inflator 15. Further, the enterprising gas port of desilting pipe 11 it is arranged at described in and the angle that is arranged between the medullary ray of the enterprising gas port of inflator 15 and the medullary ray of inflator 15 is 45 ��. The design of 45 �� of angles of the present invention, is beneficial to and forms subnormal ambient in the pipe between the filtering net and inflator 15 of desilting pipe 11, thus reaches the object improving desilting efficiency data.
In the present embodiment, described pipe body is provided with some water supply holes 112 near the tube wall of end mouth. The water of described pipe external body enters from water supply hole 112, and water mixes with the sandstone in pipe body, mud after entering. It is noted that described water supply hole 112 between filtering net and inflator 15 and described water supply hole 112 be distributed on tube wall. Further, distance between described water supply hole 112 and filtering net is the twice of the distance between water supply hole 112 and inlet mouth 151. Described water supply hole 112 is set to three, and its diameter is 10mm, is distributed on the tube wall of desilting pipe 11.
For the ease of movement, the top of desilting pipe 11 of the present invention is arranged on buoyance in water device. It is convenient to deep water negative pressure desilting system of the present invention by buoyance in water device move, treats desilting position as being transferred to the next one after having been cleared up a certain position. Wherein, described buoyance in water device is power-driven vessel 16. In the specific implementation, described power-driven vessel 16 is provided with stationary installation, it is possible to make desilting pipe 11 keep erecting the state to arranging, as arranged the channel member 161 erected to arranging on power-driven vessel 16, and skewed horizontal load part 162 is set respectively in channel member 161 both sides, form stable trilateral structure. It should be noted that, when described channel member 161 is fixed with desilting pipe 11, need to arrange hanger (not shown) in the both sides, top of desilting pipe 11, fixed by the end of guide chain (not shown) and hanger, the top on the top of guide chain with channel member 161 is connected, and then realizes the adjustment of desilting pipe 11 length.
A kind of deep water negative pressure desilting system of the present invention has been successfully applied in Yi Taizi Hydropower Project. Yi Taizi Hydropower Project is Hydropower Project newly-built on the basis of existing dam, and existing dam is clay core wall rockfill dam, overall length 1400m, and high 65m was built up in 1978. Reservoir total reservoir capacity about 60 billion cubic meter, top water-level EL1030.5 rice is the adjustment reservoir in Kai Fuxia power station, downstream. Newly-built Power Tunnels is positioned at dam right bank, is extend diversion system and pressure regulation well on the basis of original water-in and south diversion tunnel and ground power house after diversion to dam, and installed capacity is 2*60MV.
In Yi Taizi Hydropower Project, include the requirement that the approach channel of water-in 50m, width 200m length range is carried out desilting. According to on-site actual situations, bottom water-in approach channel, a high position is EL978.00 rice, the construction period depth of water 45��58m. According to underwater camera observation surface, approach channel base surface having the long-term alluvial layer of one layer of 300mm��600mm thickness, this alluvial layer is that silt is mingled with the stone of different-grain diameter.
When constructing, construction environment is required always all in raising, and ecological dredging requires that avoiding suspended load and drift confrontation surrounding body 17 to be formed in desilting process pollutes. The deep water negative pressure desilting system of the present invention can solve the problem of environmental pollution, while extracting silt, has drawn the part of contaminated water that desilting pipe 11 periphery is contaminated simultaneously, and construction environment is completely up to standard; And the desilting pipe 11 adopted directly uses steel pipe and steel plate to make, and saves great amount of cost, it is possible to reach the effect of the strength pump desilting of world advanced person. It is dark that deep water negative pressure desilting system of the present invention is particularly applicable to waters 17, and requires that extraction particle size range uses when big.
In deep water negative pressure desilting system of the present invention, when adopting an air compressor machine, it is achieved that below by way of negative pressure, mud " suction " is walked at inlet mouth 151, by malleation, mud " blowing " is walked at inlet mouth more than 151, and then complete the course of conveying of mud.
The present invention is not limited to above-mentioned enforcement mode, and when not deviating from the flesh and blood of the present invention, any distortion that it may occur to persons skilled in the art that, improvement, replacement all fall into the scope of the present invention.
