Abstract
The invention relates to a hydraulic trash remover for a bottom grid diversion dam of a power station, comprising a movable grid bar support frame, a guide wheel positioning device, a hydraulic jack, a lateral pulley positioning device, a corridor, a hydraulic jack supporting seat and fixed grid bars, wherein the hydraulic jack and a lateral positioning pulley are installed on both sides of the corridor, and the hydraulic jack is positioned on the hydraulic jack supporting seat fixed on concrete of a dam body; and the fixed grid bars are installed on the same plane of the movable grid bar support frame on the top of the dam body and are fixed on walls on both sides of the dam body, gaps between movable grid bars and the fixed grid bars installed are well adjusted, the guide wheel positioning device is installed on the lateral face of the movable grid bar support frame so as to ensure that the movable grid bar support frame can be leftwards and rightwards positioned, and a hydraulic system in a control room on the dam top is connected with hydraulic pipelines embedded in grooves on both sides of the dam body. As the structure is adopted, by controlling the hydraulic jack, the movable grid bar support frame is operated to move up and down to make reciprocating movement so that silt can be loosened, and the impulsive force of water is utilized for automatically carrying away the silt, thereby achieving the purposes of automatic trash removal and time and labor saving.
Description
Technical field
The present invention relates to the semi-automatic trash rake on barrier dam at the bottom of a kind of middle-size and small-size power station, barrier dam hydraulic pressure trash rake at the bottom of particularly a kind of power station.
Background technology
Now at the bottom of the power station barrier dam commonly used be the mode of manually removing contamination, time-consuming, also manually to remove contamination when flood comes be the work that impossible finish, can only wait for after flood goes down and can remove contamination, and wasted water resource like this, can not get better economic benefit.
Summary of the invention
Purpose of the present invention will provide barrier dam hydraulic pressure trash rake at the bottom of a kind of power station exactly, and it adopts all-hydraulic control device, reaches the purpose of automatic pollutant removal, and is time saving and energy saving.
The object of the present invention is achieved like this: barrier dam hydraulic pressure trash rake at the bottom of a kind of power station, comprise movable grizzly bar bracing frame, the directive wheel positioner, the hydraulic pressure top, the lateral register wheel, gallery, hydraulic pressure top bearing and fixing grizzly bar, hydraulic pressure top and lateral register wheel are installed in the both sides of gallery, the hydraulic pressure top is positioned on the bearing of hydraulic pressure top, hydraulic pressure top bearing is fixed on the concrete of dam body, on the same plane of dam body top movable grizzly bar bracing frame, install and fix grizzly bar, fixedly grizzly bar is fixed on the dam body both walls, adjust the movable grizzly bar and the fixing gap of grizzly bar, the directive wheel positioner is installed in the side of movable grizzly bar bracing frame, control hydraulic pressure top, make movable grizzly bar bracing frame do the reciprocating motion of upper and lower displacement, the hydraulic system in the dam crest control room and the dam body both sides pre-buried fluid pressure line of fluting is connected.
Owing to adopt said structure, so top operant activity grizzly bar bracing frame upper and lower displacement moves reciprocatingly silt is movable loose by control hydraulic pressure, utilize the impulse force of water that silt is taken away automatically, reach automatic pollutant removal, time saving and energy saving purpose.
Description of drawings
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of facing of the present invention.
Fig. 2 is the lateral view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Wherein, Fig. 1 double as Figure of abstract.
Among the figure: 1, movable grizzly bar bracing frame, 2, the directive wheel positioner, 3, the hydraulic pressure top, 4, the lateral register wheel, 5, gallery, 6, hydraulic pressure top bearing, 7, fixing grizzly bar, 8, concrete.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, barrier dam hydraulic pressure trash rake at the bottom of a kind of power station, comprise movable grizzly bar bracing frame 1, directive wheel positioner 2, hydraulic pressure top 3, lateral register wheel 4, gallery 5, hydraulic pressure top bearing 6 and fixing grizzly bar 7, hydraulic pressure top 3 and lateral register wheel 4 are installed in the both sides of gallery 5, hydraulic pressure top 3 is positioned on the hydraulic pressure top bearing 6, hydraulic pressure top bearing 6 is fixed on the concrete eight of dam body, on dam body top movable grizzly bar bracing frame 1 same plane, install and fix grizzly bar 7, fixedly grizzly bar 7 is fixed on the dam body both walls, adjust the movable grizzly bar and the fixing gap of grizzly bar, directive wheel positioner 2 is installed in the side of movable grizzly bar bracing frame 1, the left and right directions of control activity grizzly bar bracing frame 1 location, the hydraulic system the dam crest control room in and the dam body both sides pre-buried fluid pressure line of slotting is connected.
Former fixedly grizzly bar on the barrier dam dam body at the bottom of the power station is removed, hydraulic pressure top 3 and lateral register wheel 4 are installed in the position of gallery 5 both sides appropriate length, with 6 firm being fixed on the dam concrete 8 of hydraulic pressure top bearing, dam body top movable grizzly bar bracing frame installs and fixes grizzly bar 7 on the 1 same plane, fixedly grizzly bar 7 is fixed on the dam body both walls, adjust the movable grizzly bar and the fixing gap of grizzly bar, pre-buried fluid pressure line is slotted to the dam crest control room in the dam body both sides, be connected with the hydraulic system in the control room, control hydraulic pressure top 3, make movable grizzly bar bracing frame 1 do the reciprocating motion of upper and lower displacement with the movable pine of silt, utilize the impulse force of water that silt is taken away automatically, water just enters gallery automatically and generates electricity to power plant by channel for 5 li.
Hydraulic system is installed in the hoist chamber of dam, (one is two conduit under fluid pressures that connection attracts from dam body two sides, one is to fall, 3 work of control hydraulic pressure top move reciprocatingly), hydraulic system can be removed contamination according to the height that the situation that grizzly bar stops up is suitably adjusted pressure, because silt enters in the grizzly bar by the pressure of water, very fastening, adding that a plurality of grizzly bars of number stop up, the power of wanting is bigger could be had only a plurality of silt jack-up by adjusting operating pressure and could realize the loosening of silt.
