Description
Technical field
The utility model relates to a kind of sundries cleaning device of power station, specifically refers to a kind of floater salvaging system.
Background technology
Generate electricity by waterpower in power station, in majority, small hydropower station carrys out diversion by diversion canal, and diversion canal is built by the mountain often, can be by the dirts such as tree skill wood on mountain after exposing to the weather, and introduce the hydraulic turbine and its blade is smashed and destroyed Hydropower Unit.Therefore to be operated in power station be very important in blowdown, data shows according to statistics: whole nation blowdown of small hydropower station in each, substantially all adopt traditional trashrack to add the mode that human assistance is removed contamination, inefficiency, often cause that water flowing is smooth, water source loss is serious, during blowdown operation, labor strength is greatly and extremely dangerous, blowdown quality is low, and destroying equipment for hydroelectric station often has generation, thereby brings serious economic loss to power station.The blowdown in China power station, is all to adopt trashrack form, and with the artificial dirt of removing, efficiency is low, often causes water flowing not smooth, water source heavy losses, and operating worker labour intensity is large and be absolutely unsafe, and filth-discharging effect is poor, and infringement power station equipment often has generation.Trash rake is applicable to clear up the utensil of garbage on water, and trash rake is conventionally arranged on gantry row and hangs on, utilize slusher upper and lower, open and close and movement that row hangs realizes cleaning and the transfer of garbage on water.
The cleaning of current power station floating thing has two class manner of cleaning up: 1 trash rake, the operation that the motion dependency line of trash rake hangs, in some special environment, the installation that row hangs is restricted, also just limited the use of trash rake, at the mountain area of China small hydropower station, the water surface, inefficiency are manually cleared up in main or dependence; The pick-up boat of 2 movable types, there is large, the inefficient defect of energy consumption in this salvaging mode, and is subject to the restriction of the water surface, be difficult to use, and floater exists the edge in waters often, has become the salvaging dead angle of pick-up boat in the place of water depth deficiency.
Utility model content
The purpose of this utility model is to provide a kind of floater to salvage system, and the dependency line that solves current power station trash rake existence hangs, uses the problem that the area that is subject to geographical conditions restriction, salvages is little, be limited in scope.
The purpose of this utility model is achieved through the following technical solutions:
A kind of floater is salvaged system, comprise and tilt to be arranged on the filtration fence on the head of drainage weir, river course, also comprise that is placed on the sliding machine filtering on fence, a bucket rake being connected through the hinge is installed on described sliding machine, bucket rake and sliding machine form the structure for bearing and installing of floating thing, also comprise that one extends to the fixed platform the place ahead water surface of drainage weir from drainage weir crown portion, the lifting appliance of bucket rake is installed in described fixed platform; Draw-gear is also installed in described fixed platform, described draw-gear comprises a launching tube, the one end opening other end of launching tube forms blind end, at blind end, be provided with through wires hole, in launching tube, be provided with a push pedal, between push pedal and the blind end of launching tube, spring is installed, on described launching tube, be provided with a bar shape trench hole, in push pedal, be connected with the handle that pushes away through bar shape trench hole, also comprise a spearhead, on spearhead, be connected with pull rope, pull rope is connected with haulage gear through through wires hole; Also comprise a compression motor, the output of compression motor drives rotating disk by reductor, is provided with drive rod on rotating disk, and drive rod converts the circular motion of rotating disk to the rectilinear motion that pushes away handle.The utility model utilizes existing bucket rake as the theme operation of removing contamination, by bucket rake is arranged on sliding machine, realize the slip of bucket rake, then build a fixed platform, by a hoisting mechanism is set in fixed platform, sliding machine is drawn and promoted, utilize sliding machine along the slip of filtering fence, thereby complete the salvaging of floater and transfer, for the trash rake of existing gantry frame type, it is little that it has occupied ground, be not subject to the advantage of geographical conditions restriction, and floating thing is directly salvaged disembarkation, be convenient to cleaning, by external force, move and push away handle, pushing away handle moves along bar shape trench hole, drive push pedal is moved to the blind end of launching tube, and then Compress Spring, the pull rope of spearhead is through through wires hole, spearhead is positioned at launching tube, and near push pedal, when relieving pushes away handle, spring recovers deformation and drives push pedal to accelerate outwards to move, spearhead obtains kinetic energy and penetrates at high speed, finally fall on the floating thing of the water surface, on spearhead, there are a plurality of hangnails, be used for hanging over floating thing, owing to being deposited in floating thing on front waters, power station under the wave action of water, be easy to form staggered bonding monoblock, hook is mobile can drive large stretch of floating thing to move, utilize haulage gear that pull rope is reclaimed, can be by large-area floating thing band the drainage fence to power station, be convenient to salvage, so, the working area that has solved existing trash rake existence is limited, and broad this contradiction of floater area, greatly improved the operating efficiency of trash rake, after utilizing compression motor to drive reductor to slow down, can rotate very slow, increase moment, drive rotating disk moves in a circle, and the drive rod drive on rotating disk pushes away handle and moves in bar shape trench hole, circular motion is converted to the rectilinear motion that pushes away handle, thereby Compress Spring, replace people to drive and push away handle, realized semi-automation, reduced operating personnel's labour intensity.
