Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a rotary silt-clearing device for a water conservancy gate. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Gates are control facilities used to close and open water discharge channels. They are an important part of hydraulic structures and can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. In order to ensure that the work of water conservancy gates is not affected, it is necessary to regularly use dredging equipment to clean the sediment and silt adhering to the gates.

[0003] Publication No. "CN213233342U" provides a hydraulic gate desilting device, which is equipped with a torsion spring. Since the rotating rod of the scraper is rotatably connected to the protrusion via a bearing, the torsion spring can give a force to the scraper, and the scraper is tilted toward the gate under the force, and the blade of the scraper is made to fit the gate. There is no need to adjust the scraper, and the gate is driven up and down by a motor to achieve cleaning of the gate.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the hydraulic gate dredging device can clean the gate, the dredging structure can only dredge the front end face of the gate, and cannot dredge the rear end face of the gate at the same time. The dredging range is limited, and the scraper in the dredging device is applied by the force given by the torsion spring, so that the scraper is forced to tilt and fit toward the gate for scraping. However, in actual use, this dredging structure is prone to missed scraping once the front end face of the gate becomes uneven, and its practicality is poor. Utility Model Content

[0035] Working principle: During the closing and use of the blocking gate 6, sand and silt will adhere to its front and rear end surfaces. When it is necessary to desilt the front and rear end surfaces of the blocking gate 6, the staff first starts the waterproof motor 512, so that the waterproof motor 512 drives the driving shaft 514 to rotate, and the driving shaft 514 drives the first cleaning roller 52 to rotate through the first connecting flange 53. At the same time, the driving shaft 514 drives the driving pulley 513 to rotate, so that the driving pulley 513 drives the driven pulley 59 to rotate through the transmission belt 511, and the driven pulley 59 drives the driven shaft 58 to rotate, and then the driven shaft 58 drives the second cleaning roller 57 to rotate through the second connecting flange 56. Then the staff can drive the blocking gate 6 to move upward and open through the worm gear elevator 1 (refer to Figure 2), during this process, the rotating first cleaning roller 52 and the second cleaning roller 57 will rotate and desilt the silt and mud adhered to the front and rear end surfaces of the blocking gate 6; at the same time, the staff starts the self-priming water pump 42, so that the self-priming water pump 42 works to pump the water in the external water storage tank to the connecting tee 43 through the water inlet hose 44, and the connecting tee 43 will divert the water to the first guide pipe 41 and the second guide pipe 45, and then the water in the first guide pipe and the second guide pipe 45 will be sprayed downward on the upper side of the annular side of the first cleaning roller 52 and the second cleaning roller 57 through a plurality of spray heads 46, so as to rinse the rotating first cleaning roller 52 and the second cleaning roller 57, thereby ensuring the desilting effect of the first cleaning roller 52 and the second cleaning roller 57. After the desilting is completed, the staff only needs to turn off the waterproof motor 512 and the self-priming water pump 42.
