Description

Power station is with blocking dirty device

Technical Field

The utility model relates to a block dirty device, especially a power station is with blocking dirty device.

Background

A hydropower station, called a hydroelectric power plant in its entirety, is a plant that converts potential energy and kinetic energy of water into electrical energy. The basic production process is as follows: water is drawn from the high position of a river or other reservoirs, the water turbine is driven to rotate by the pressure or the flow velocity of the water, the gravitational potential energy and the kinetic energy are converted into mechanical energy, and then the water turbine drives the generator to rotate, so that the mechanical energy is converted into electric energy. The water flow inevitably carries a plurality of Xu Zawu, and in order to prevent sundries from damaging the water turbine, a trash blocking device is usually arranged at a water inlet and a water outlet of a hydropower station at present, but the trash blocking device often causes sundries to be accumulated in front of the trash blocking device, and when the sundries are excessively accumulated, great head loss is generated, so that the sundries in the trash blocking device need to be regularly cleared, and most of the sundries are cleared through manual drainage, so that time and labor are wasted, and potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a power station is with blocking dirty device. The trash remover can remove sundries accumulated on the front side of the trash rack regularly, reduce water head loss, save time and labor and reduce potential safety hazards.

The technical scheme of the utility model: the utility model provides a power station is with trash device, includes trash rack and the operation panel of trash rack upside, its characterized in that: the front side of the trash rack is provided with a support, a reciprocating lead screw in the vertical direction is arranged in the support, a trash collecting box is arranged on the reciprocating lead screw through a lead screw seat and comprises two side plates used for installing the lead screw seat, a discharging plate is arranged on one side of each side plate through a rotating shaft, a sieve plate is arranged between bevel edges of the side plates, and a waste bin is arranged on the upper side of the operating platform.

In the above-mentioned trash rack for hydropower station, the through hole corresponding to the bracket is arranged in the operation platform.

In the trash rack for hydropower stations, the guide block is arranged at the upper end of the material placing plate.

In the above-mentioned trash rack for hydropower station, the upper end of the inner side of the bracket is provided with a wedge corresponding to the guide block.

In the trash holding device for the hydropower station, the upper end of the bracket is provided with a motor for driving the reciprocating screw rod to move.

In the trash rack for the hydropower station, the sieve plate is in an arc shape, and sieve pores are uniformly distributed in the sieve plate.

Compared with the prior art, the utility model discloses a reciprocating screw rod drive is received dirty case and is made periodic elevating movement, can collect debris to receiving in the dirty case, when receiving dirty case and move to the operation panel upside, the drain board in receiving the dirty case can open through the cooperation of guide block and voussoir and receive dirty case, will receive in the dirty case debris arrange to the garbage bin to accomplish periodic cleaning, need not staff's offal and salvage debris, not only labour saving and time saving has reduced the potential safety hazard moreover.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example 1. A trash rack device for a hydropower station, which is configured as shown in FIGS. 1 to 2, and includes a trash rack 1 and an operation table 10 on an upper side of the trash rack 1, wherein: stop 1 front side of dirty grid be equipped with support 2, be equipped with the reciprocal lead screw 3 of vertical direction in the support 2, be equipped with through screw rod seat 4 on the reciprocal lead screw 3 and receive dirty case, receive dirty case including two blocks of curb plates 5 that are used for installing screw rod seat 4, curb plate 5 is equipped with blowing board 7 through pivot 6 on one side, be equipped with sieve 8 between the hypotenuse of curb plate 5, the 10 upsides of operation panel are equipped with dump bin 12.

The upper side of the operating platform 10 is provided with a through hole 13 corresponding to the bracket 2.

The upper end of the discharging plate 7 is provided with a guide block 14.
