[0002] The hydraulic structures of a hydropower station refer to various water conservancy engineering buildings and facilities required for the construction and operation of a hydropower station. Among them are diversion canals, which guide water from reservoirs or rivers to turbine units for power generation. Diversion canals are usually constructed of concrete, reinforced concrete or pipes. The water flow in the diversion canal is affected by gravity and gravity, and will generate a certain impact force when flowing. For a long time, the water flow has been constantly impacting the surface of the diversion canal, which may cause pits on the surface. If the pits on the surface of the diversion canal are not cleaned in time, it will further expand and aggravate the wear and erosion of the canal, shortening the service life of the canal.

[0026] Example

[0027] like Figure 1-4 As shown, the utility model proposes a surface pit cleaning device for hydraulic structures of a hydropower station, including a support sleeve rod 2, on which a shoulder frame 1 is provided for fitting and clamping the user's shoulder. The position where the shoulder frame 1 contacts the shoulder can be set as a sponge pad, which is used to avoid discomfort caused by being too hard and contacting the shoulder for a long time. The shoulder frame 1 is fixedly connected with an elastic armpit strap 3 for clamping the user's armpit to prevent the shoulder frame 1 from detaching from the user's shoulder. The material of the elastic armpit strap 3 has a certain elasticity, which allows the user to put it on and take it off quickly. It also includes: a suction and discharge mechanism, which is installed on the support sleeve rod 2 and is used to flush the surface pits of the water diversion channel after extracting water from the water diversion channel; an adjustment mechanism slidably connected to the support sleeve rod 2 for supporting the suction and discharge mechanism to move and clean the pits of different depths; and a reset mechanism arranged on the support sleeve rod 2 for restoring the suction and discharge mechanism to its original position.

[0028] Furthermore, the suction and discharge mechanism includes a water pump 4 installed on the support sleeve rod 2, and a water suction pipe 41 and a water delivery pipe 42 are provided at the bottom of the water pump 4, and the materials of the water suction pipe 41 and the water delivery pipe 42 are both hoses. The length of the water suction pipe 41 is greater than the maximum length of the extension of the telescopic rod 6, and its function is to ensure that the bottom of the water suction pipe 41 is submerged in the water, and then it can absorb water for the water pump 4. The end of the water suction pipe 41 away from the water pump 4 is fixedly connected with a filter head 44, and the function of the filter head 44 is to filter large particles of impurities in the water to prevent large particles of impurities from blocking the water pump 4 and then affecting the operation of the water pump 4. The end of the water delivery pipe 42 away from the water pump 4 is fixedly connected with a high-pressure nozzle 43, and the high-pressure nozzle 43 generally refers to a nozzle device for generating high-pressure water flow. The end of the water delivery pipe 42 close to the water pump 4 is set to be wavy.

[0029] Among them, the adjustment mechanism includes a telescopic rod 6 slidably connected to the support sleeve rod 2, and the bottom end of the telescopic rod 6 is fixedly connected with a fixed buckle 64 for clamping the water pipe 42. The function of the fixed buckle 64 is to fix the water pipe 42 on the telescopic rod 6 to prevent the water pipe 42 from moving or shaking during use. This helps to ensure the stability and safety of the water pipe 42 during operation. The bottom end of the telescopic rod 6 is fixedly connected with a support block 61, and the end of the support block 61 away from the telescopic rod 6 is fixedly connected with a clamping block 62. The end of the clamping block 62 away from the support block 61 is provided with a protrusion, and the function of the protrusion is to judge whether the high-pressure nozzle 43 is aligned with the flushing pit by the contact with the flushing pit. The clamping block 62 is provided with an arc-shaped groove 63 for the high-pressure nozzle 43 to be clamped.

[0030] Secondly, the adjustment mechanism also includes a slide groove 21 provided on the support sleeve rod 2 , and a handle 22 is slidably connected inside the slide groove 21 , and one end of the handle 22 in the slide groove 21 is fixedly connected to the telescopic rod 6 .

[0031] Furthermore, the reset mechanism includes a support rail 5 fixedly connected to the support sleeve rod 2, and a telescopic groove 51 is opened on the support rail 5. The interior of the telescopic groove 51 is slidably connected with a plurality of linearly arranged sliding sleeves 52. The sliding sleeve 52 is fixedly sleeved with one wavy end of the water pipe 42. The middle part of the sliding sleeve 52 is located inside the telescopic groove 51 and a reset spring 53 for pulling the sliding sleeve 52 to restore its original position is provided. Both ends of the reset spring 53 are fixedly connected to the corresponding sliding sleeve 52.

[0032] In this embodiment, when it is necessary to use the surface flushing and cleaning device of the hydraulic structure of the hydropower station, Figure 1As shown, first clamp the shoulder frame 1 on the right shoulder, then pull the elastic underarm band 3 to make the elastic underarm band 3 larger, then pass the left hand under the elastic underarm band 3, and then make the elastic underarm band 3 clamp the armpit of the left arm. At this time, you can stand on the edge of the water diversion channel and check the flushing pit on the water diversion channel. When a flushing pit is found, you only need to place the bottom of the suction and discharge mechanism and the adjustment mechanism into the water diversion channel, and make the filter head 44 at the bottom of the suction pipe 41 submerge in the water, and then shake the right shoulder to drive the shoulder frame 1 and the support sleeve rod 2 and the telescopic rod 6 to move, so that the block 62 at the bottom of the telescopic rod 6 is against the flushing pit. When the height of the flushing pit is too deep or too shallow, manually slide the handle 22 in the slide groove 21 so that the handle 22 drives the telescopic rod 6 to slide on the support sleeve rod 2. At the same time, the wavy end of the water pipe 42 is extended and retracted in the telescopic groove 51 through the sliding clamp 52, and when the hand does not hold the handle 22, the water pipe 42 clamped by the sliding clamp 52 can be restored to its original position through the elastic pulling force or pushing force of the reset spring 53, and finally the clamping block 62 at the bottom of the telescopic rod 6 can be pressed against the center of the flushing pit. At this time, the water pump 4 on the support sleeve 2 can be started, and after the water pump 4 is started, the water in the water diversion channel is pumped to the water pipe 42 through the suction pipe 41, and finally the water is flushed into the flushing pit through the high-pressure nozzle 43 in the arc groove 63, so that the debris in the flushing pit is washed away, which is simple and easy to operate.
