Description

[0002] A hydropower dam is a water retaining structure, also called a water retaining dam, which is a component of a hydropower station. In order to discharge water, a gate is designed on the water retaining dam, and a water retaining gate plate is set in the gate. By removing the gate plate, the gate can be exposed to discharge water, and by moving the gate plate back to block the gate, water can be prevented from passing. However, during long-term use, as the gate plate is soaked in water, debris in the water will adhere to the gate plate, which will cause erosion to the gate plate in the long run and affect its service life. At present, in response to this situation, most staff members paddle a small boat to the gate position and use tools to clean the surface of the gate plate.

[0029] Reference Figure 1-10 A device for removing foreign matter adhered to the surface of a hydropower dam gate plate. The push-pull member 5 includes a hinge block 51 connected to a reinforcing rod A31. The hinge block 51 is hinged with a hinge seat 52 on the outside. A telescopic rod 53 is connected to the hinge block 52. A connecting seat 54 is provided on the outside of the telescopic rod 53.

[0030] In the present invention, the shaft A1 is connected between the gates of the hydropower generation dam, and the two connecting seats 54 are also connected to the opposite surface positions of the gates of the hydropower generation dam, and the connecting seats 54 can rotate; the state in which water cannot flow through the gate is that the bottom of the plate body 41 contacts the gate, and the plate body 41 blocks the entire gate position. When it is necessary to drain water through the gate, the staff controls the two telescopic rods 53, which can also be hydraulic rods, as long as they can play the effect of extending and pushing or retracting back. The telescopic rod 53 retracts and pulls the hinge block 51 and a reinforcing rod A31. At this time, under the support of the connecting structure A2, the entire gate body rotates and lifts upward along the arc trajectory with the shaft A1 as the axis, and the shaft cylinder A211 and the shaft cylinder B221 rotate on the surface of the shaft A1. After the plate body 41 is lifted, the gate is exposed to allow water to flow through, wherein the hinge block 51 is close to the bottom of the plate body 41; When the shaft cylinder B221 rotates on the surface of the shaft rod A1, the shaft cylinder B221 drives the transmission assembly A72 to descend through the connecting rod C61 and the connecting rod D62 until half of the transmission plate 723 is located in the water flow. In this way, under the impact of the water flow on the transmission plate 723, the multiple transmission plates 723 are constantly replaced, so that the multiple transmission plates 723 drive the shaft rod B711 to rotate through the connecting cylinder 721. The rotation of the shaft rod B711 drives the two sprocket wheels A712 to rotate. The rotation of the two sprocket wheels A712 drives the two sprocket wheels D123 to rotate through the transmission chain. The two sprocket wheels D123 drive the shaft rod C122 to rotate between the two support blocks 121. The rotation of the shaft rod C122 drives the two bevel gears B124 to rotate. The bevel gear B124 engages with the bevel gear A113 to drive the installation shaft B111 to rotate. The rotation of the two installation shafts B111 drives the two sprocket wheels C112 to rotate. The two sprockets C112 rotate and drive the two sprockets B10 through the transmission chain, and the mounting shaft A101 drives the two reciprocating screw rods 9 to rotate. The two reciprocating screw rods 9 drive the displacement plate 131 to move up and down, and the displacement plate 131 drives the cleaning rod 133 to move on the surface of the plate body 41 through the movable connecting piece 132 and clean it. The upper and lower positions of the sides of the cleaning rod 133 in contact with the plate body 41 are all inclined surfaces, which improves the cleaning and scraping effect. In addition, in order to make the extrusion force between the cleaning rod 133 and the plate body 41 appropriate and not affected by the arc surface, when the cleaning rod 133 cleans to the arc surface vertex of the plate body 41, the extrusion force received by the spring 1322 is the largest, and the screw rod 1321 can interact in the movable hole 1312, which does not affect the extrusion and release of the spring 1322, and the distance between the cleaning rod 133 and the plate body 41 also changes with the change of the arc surface of the plate body 41. When the transmission plate 723 cannot be immersed in the water flow to a suitable depth, the staff can make adjustments in time. When adjusting, first remove the transmission chain on the sprocket A712 and the sprocket D123, and then the staff loosen the bolts in the locking hole 66 to release the restrictions on the connecting rod C61 and the connecting rod D62 and the shaft cylinder B221. Then the staff can use tools such as jacks to support the connecting rod C61 and the connecting rod D62, and then unscrew the clamping rod 65 in the clamping hole A64 and the clamping hole B671. The staff lifts or uses a jack to rotate the connecting rod C61 and the connecting rod D62 with the shaft cylinder B221 as the rotation axis for adjustment. Upward or downward, when the transmission plate 723 is immersed in the water too deeply, the connecting rod C61 and the connecting rod D62 are rotated upward and lifted; when the transmission plate 723 is immersed in the water too shallowly, the connecting rod C61 and the connecting rod D62 are rotated downward and lowered; after adjustment, the clamping hole A64 is aligned with the clamping hole B671 and the clamping rod 65 is screwed into it, and then the bolt in the locking hole 66 is tightened to stably lock the connecting rod C61 and the connecting rod D62 with the shaft cylinder B221 together; finally, according to the distance between the sprocket A712 and the sprocket D123, the length of the transmission chain is adjusted, and the transmission chain is sleeved on the sprocket A712 and the sprocket D123; When it is necessary to block the gate to prevent water from passing through, the staff extends two telescopic rods 53 to push the gate body, so that the plate body 41 passes through the connecting structure A2 and rotates downward along an arc trajectory with the shaft A1 as the axis to block the gate. At this time, the shaft cylinder A211 and the shaft cylinder B221 rotate on the surface of the shaft A1, and the shaft cylinder B221 drives the power structure 7 upward through the connecting structure B6, that is, the transmission component A72 upward, and when the water flow is reduced or even stopped, half of the transmission plate 723 leaves the water flow until it is completely exposed and does not rotate, and the cleaning work is also completed.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
