Abstract

The utility model relates to an apparatus for cleaning a waste barrier, comprising a frame and tooth harrows. The utility model has a tackle, pulley wheels are arranged on base plates of both sides of the tackle and are arranged in sliding rails of both sides of the frame, cross beams of the tackle are arranged on the base plates, the tooth harrows are fixed on the cross beam, a motor drives the tackle to move up and down through a drive mechanism, the back face and the top of the waste barrier are provided with rotating harrows under which a conveying apparatus is arranged, and the conveying apparatus is used for conveying firewood selected from the tooth harrows by the rotating harrows. The apparatus for cleaning waste barrier is made of the technical proposal so as to have the advantages of simple structure, convenient installation and reliable operation, and the utility model can replace manpower to automatically cleaning dirt.

Description

The trashrack trash rake

The utility model relates to a kind of power station trashrack sewage disposal apparatus.

Trashrack is one of power station visual plant, its effect be will enter weeds, branch and dirt retaining in the hydraulic turbine current outside turbine chamber, make totally stably that current enter the hydraulic turbine smoothly, promote hydraulic turbine running.Must in time be salvaged cleaning by these weeds dirts that trashrack blocks, otherwise before will getting lodged in grid, current can't pass through, influence unit running, traditional Refloatation method is upwards one to harrow a rake the soil level salvaging with creeper along grizzly bar by artificial, and labour intensity is very big, especially to flood season, korneforos faggot dirt is more, and the several people around the clock salvages also of no avail, and generating is greatly affected.So far also do not have a kind of gratifying, can replace the artificial automatic pollutant removal equipment of salvaging.

The purpose of this utility model is exactly will provide a kind of can replace the artificial trashrack automatic pollutant removal device of salvaging dirt.

The purpose of this utility model is to realize like this, the trashrack trash rake comprises framework and tooth harrow, before framework places trashrack, it is characterized in that: it has a coaster, pulley (10) is housed on the coaster both sides foundation slabs (9), places in the slide rail (8) on framework (6) both sides, coaster crossbeam (11) both sides are with bearing (13), bearing is contained on the foundation slab (9), and tooth harrow (12) is fixed on the crossbeam; Motor (1) and rope drum (4) are contained in frame roof, and motor drives rope drum by Worm and worm-wheel gearing (2), drive coaster and move up and down, and a control device is arranged on the coaster foundation slab, mention when descending when the control tooth harrow rises to change; At trashrack (14) top, the back side, rotary harrow (15) is housed, rake teeth passes trashrack, and rotary harrow below rotary harrow, has a conveying device (19) by rope drum main shaft driven rotary, carries rotary harrow to choose the faggot that falls from tooth harrow.

The trashrack trash rake that adopts technique scheme to make, simple in structure, be convenient to install, reliable, can replace artificial automatic pollutant removal, removed people's heavy work, can improve the operational efficiency in power station.Above-mentioned trash rake is not only applicable to each large, medium and small power station, and is applicable to the dirt-blocking dirt-cleaning of each canal for water conveyance, and the scope of application is extremely wide.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the front view of the utility model grizzly bar forward part.

Fig. 2 is a lateral view of the present utility model.

Fig. 3 is the upper arresting pin schematic diagram.

In the drawings, framework 6 places before the trashrack 14, and framework is made by channel-section steel, and notch inwards, in have two round steel to do pulley rail 8, on the coaster both sides foundation slab 9 pulley 10 is housed, place in the slide rail 8, bearing 13 is equipped with on coaster crossbeam 11 both sides, and tooth harrow 12 is fixed on the crossbeam, can rotate automatically.Motor 1 drives rope drum main shaft 5 by Worm and worm-wheel gearing 2, rope drum 4 moves up and down by steel cable 7 extension pulleys, upper arresting pin 16 and lower position block 17 are arranged on the coaster foundation slab 9, upper arresting pin is a wedge shape, spring 20 is arranged thereafter, pull bar 21 and depression bar 22, scotch 23 on one is arranged at the top of framework 6, when coaster rises, upper arresting pin blocks tooth harrow, make it vertical with grizzly bar, rake teeth puts in the trashrack, when rising near the top, last scotch 23 moulded rods 22, make pull bar 21 drive upper arresting pin 16 withdrawals, tooth harrow 12 repeatedly drops down onto lower position block 17 positions, and rake teeth leaves grizzly bar, simultaneously, electrical installations control motor 1 drives coaster and falls, in base of frame scotch 18 is once arranged, when coaster fell near the bottom, following scotch 18 blocked tooth harrow, coaster continues to move down, tooth harrow 12 rotates up relatively, and after slipping over upper arresting pin, upper arresting pin blocks tooth harrow, make it perpendicular to trashrack 14, rake teeth puts in the grizzly bar, and the driven by motor of electrical installations control simultaneously coaster begins to rise, the faggot on the tooth harrow cleaning grizzly bar.Rotary harrow 15 is arranged at top, the trashrack back side, turn clockwise by the V-belt drive by three horn rings 3 on the rope drum main shaft, rake teeth passes grizzly bar, cooperate with tooth harrow, one dolly 19 is arranged below rotary harrow, when tooth harrow was hung faggot and risen to the top, rotary harrow 15 was provoked the faggot on the tooth harrow, sends in the following dolly.To bigger hydroelectric power plant, machine is organized a performance several more, can adorn a light-duty conveyer belt at the back side of trashrack, rotary harrow is chosen the faggot that falls deliver to the appointed place automatically.
