Wherein, the water inlets of some hydropower stations are only provided with the trash racks and are not provided with any trash cleaning machine. There is therefore a need for a trash rack flushing device and system that addresses such problems.

The third spring 204f is a compression spring and plays a role of return.
Furthermore, the trigger 204 further includes a manual pressing rod 204g disposed at an end of the spray gun housing 103, one end of the manual pressing rod 204g is fixedly connected to the moving ring 203b, and a fourth spring 204h is further disposed on the outer periphery of the other end of the manual pressing rod 204g and outside the spray gun housing 103. The invention can not only be adjusted in a self-adaptive way, but also be adjusted manually, namely when an operator manually pushes and presses the manual pressing rod 204g, the long connecting rod thereof can also push the moving ring 203b to move, namely the movement of the control arc-shaped plate 202a, thereby realizing the control of the aperture size of the nozzle 201.
When the washing device is used, the washing device is firstly arranged on the downstream side of the trash rack of the hydropower station, so that the washing device is directly opposite to the trash rack, and when the water spraying gun is required to wash away the garbage accumulated on the trash rack, an operator only needs to operate the handle 103a to enable the water flow sprayed out of the nozzle 201 to be aligned with the position of the garbage. The flushing of the waste in the immediate vicinity is a water pressure. When the garbage at a far position needs to be flushed, the garbage at the far position has two conditions, namely the garbage at a high position or the garbage at the left side and the right side. It is necessary to raise the nozzle 201 or move the nozzle 201 leftward or rightward. Taking the lifting nozzle 201 as an example, when the tail end of the spray gun housing 103 is pressed to lift the nozzle 201, the end of the longitudinal trigger rod 204a inside the spray gun housing 103 is squeezed by the first arc-shaped surface 102a on the top post 102, and gradually moves towards the nozzle 201, and drives the first wide gear 203f-1 to rotate, and then drives the swing arm 203e to swing to push the moving ring 203b to move, at this time, the arc-shaped plate 202a gradually slides downwards along the conical surface of the nozzle 201, the aperture of the nozzle 201 becomes small, under the condition that the pressure of the booster pump is unchanged, the water flow at the water outlet of the nozzle 201 is sprayed farther, and therefore the requirement of cleaning the far garbage is met. The principle is the same when the nozzle 201 is swung to the left or right. The device can also be adjusted manually, namely when an operator manually pushes and presses the manual pressing rod 204g, the long connecting rod can also push the moving ring 203b to move, namely the movement of the arc-shaped plate 202a is controlled, so that the control of the aperture size of the nozzle 201 is realized.
It should also be noted that the corresponding chamber or slot in the lance housing 103 allows all of the above components to be properly installed. The device can adaptively change the aperture of the nozzle of the water gun through the arrangement of the spray gun assembly and the adjusting assembly, so as to change the flow rate and the pressure of water flow, thereby meeting the flushing requirements of different distances.
