Description

Rope control buoy quoit

Technical field

The present invention relates to the interim lifesaving appliance of use waterborne, buoy quoit accurately to render to the distance far exceeding buoy quoit of directly jettisoninging, and can finely tune rescue position on demand.

Background technology

At present, water survival mainly relies on ship and buoy quoit to implement the work of lifesaving.The general adult's buoy quoit of 2.5 kilogram weight of standard generally only has several meters to tens meters when jettisoninging, can only rescue very near distance.Will jettisoning when running into flow rate of water flow and being larger accurately more difficult, even if position of sometimes jettisoninging puts in place and saved person differs and catches buoy quoit surely in time, thus washed away the causing of buoy quoit is rescued unsuccessfully.Remote accurately input buoy quoit and the method that rescue is never simple and effective in turbulent water.Mainly contain two classes about remote patent of throwing in buoy quoit at present, one is with pressure gas, and gunpowder or mechanical spring are jettisoninged, if CN101982371A, CN201842236U, CN202609055U etc. in Chinese patent are this series products.These products are not all suitable for lifesaving in rapid stream, are difficult to operation, could again jettisoning if the buoy quoit that failure of once jettisoninging needs to spend the long period to regain has dished out also loads.Another kind of is that as CN202609055U, CN202439834U etc., this product is not suitable for turbulent water equally in the mode of electric remote control from boat buoy quoit, and control difficulty, and electric remote control product maintenance cost is very large, reliability is low.

Show from the pertinent data retrieval comprising Chinese patent, have not yet to see and utilize rescue rope, steady ring and guiding rudder plate accurately to control the product of buoy quoit position and the relevant report of rescue mode.

Summary of the invention

In order to solve the difficulty of prior art at long-range accurate input buoy quoit, the object of the invention is, based on the buoy quoit of existing standard, to propose a kind of failure-free, easily, can stormy waves be stood, and a kind of water life saving apparatus of buoy quoit placement position can be finely tuned as required.The present invention discloses in left bank simultaneously, right bank, uses rope of the present invention to control the method for buoy quoit under flowing water and hydrostatic different situations.

The present invention solves the method that its technical matters adopts: below universal standard buoy quoit, install the guiding rudder plate being approximately perpendicular to horizontal surface with fixing or detouchable mode, guiding rudder plate is plane tabular, can be rectangle, round rectangle, trapezoidal, triangle, semicircle, ellipse, half elliptic, polygon or cater to the irregular shape of buoy quoit section, is preferably round rectangle from consideration rudder plate shape that is practical and safety.Buoy quoit side installs fixing steady ring from two symmetric positions of rudder plate normal certain angle or ties up by back-to-back VELCRO the steady ring that cingulum installs adjustable position, be respectively used to left bank and right bank rescue and hydrostatic rescue, each steady ring and rudder plate two ends are apart from unequal, form non-equicrural triangle, the side of stressed deflection steady ring and rudder plate line of centres when making rudder plate be subject to water impact, rescue rope is by directly to bundle or detouchable mode (as hook with safety tong) is connected with one of them steady ring.

Know-why of the present invention is, the non-equicrural triangle position angle relation of steady ring and rudder face causes certain rudder face to meet water angle.Under the impact effect of current, the pulling force of rescue rope and current are made a concerted effort in departing from riverbank state to the application force of rudder plate and buoy quoit, buoy quoit can be made to float voluntarily from riverbank with certain speed release rescue rope.As long as rescue rope length is enough, end user, by controlling the length of rescue rope and adjusting in the position on bank, can accurately render to buoy quoit the distance far exceeding buoy quoit of directly jettisoninging in the mode of similar kiteflying, and can finely tune rescue position on demand.

The present invention is especially outstanding, and when water flow velocity is larger, the time that buoy quoit drift boat puts in place is shorter, and rescue result of use is better.In torrent waters, as long as rescue people stands in the suitable distance in upstream, by with the speed being less than current release rescue rope, just buoy quoit can be thrown in fast to assigned address.

In water velocity, comparatively slow or standing water rescue still can use the present invention, for right bank rescue, thrown in rope control lifesaving by the place that the downstream of rescuer is slightly far away and ensphere water, rescue group is upstream run, run while discharge rescue rope, release rope speed and be less than running speed, by controlling to release rope length and running speed can control the distance of buoy quoit offshore.Complete static waters is not easy to finely tune buoy quoit position, appropriateness can increase and release rope length, allows the inswept saved person of rescue rope connecting buoy quoit and rescuer, saved person catch rescue rope can along rope grip to buoy quoit.

Rescue distance to be farthest correlated with rescue rope length, rudder plate area, steady ring angle position, water velocity, rescue rope hygroscopic character, rescue rope unit weight, riverbank height and rescue skill.Such as, rescue rope hygroscopic character is larger, and after rescue rope gets wet, weight is larger, and its sag of chain is also larger, and when rescue rope is immersed in water, the resistance of water can have a strong impact on the pulling force angle of rescue rope.Preferred steady ring position depart from rudder plate centre normal direction about 10 degree to 60 degree between choose by water velocity difference.In the larger waters of flow velocity, steady ring is better in larger deviation angle effect, flow velocity about 2 meter per second time preferred steady ring position be positioned at and depart from rudder plate centre normal about 45 degree of positions, flow velocity about 1 meter per second time steady ring be positioned at that to rescue effect when departing from rudder plate centre normal 30 degree of positions better, can float fast and put buoy quoit and put in place.At standing water or flow velocity comparatively bay, steady ring is arranged on from rescuing effect during rudder plate centre normal 10 ~ 20 degree of Angle Position better, can reduce distance of running.Advise departing from rudder plate centre normal one o'clock position and arranging fixing steady ring to be applicable to the Quick rescue of most of river flow being positioned at, the steady ring being aided with adjustable position is unsuitable for the situation of stationary positioned ring for flow velocity.

In order to reduce rescue time, advise at rescue rope end installing card button hook with safety tong, for connecting the safety link of rescue rope and diverse location fast.

Experiment shows, under the state of 1 meter per second left and right flow velocity and riverbank is high 7 meters, the 4mm polypropylene fibre rescue rope of 100 meters long can be put into offshore about 60 meters of places far away buoy quoit drift.
