Description

Technical Field

[0001] This application relates to the field of gate cleaning technology for water conservancy projects, and more specifically, to a cleaning device for gates in water conservancy projects. Background Technology

[0002] In the field of water conservancy engineering, we carry out engineering planning and design, on-site construction, project budgeting, and maintenance and repair of water conservancy equipment. For example, we construct different types of hydraulic structures such as dams, dikes, spillways, sluices, canals, ferries, rafts, and fishways. In water conservancy projects, gates are used to facilitate the closure and opening of water discharge channels.

[0003] In current screw-driven gate systems, the lower end of the screw is rotatably connected to the gate plate via a bearing, and the screw is threadedly connected to the gate frame. Adjusting the screw's position raises and lowers the gate plate. However, this screw-driven lifting method is susceptible to damage. When the screw is exposed to outdoor environments for extended periods, rainwater corrosion causes it to rust. Furthermore, prolonged exposure to humid environments fosters the growth of microorganisms (including moss) on the screw's surface. As the screw rotates, a thin film of iron oxide (rust) or other metal oxides forms on its surface. This film is not smooth but rather very rough, significantly increasing the coefficient of friction between the screw and its mating components (such as nuts and bearings). This results in difficulty rotating the screw and hinders gate plate lifting.

[0004] In view of this, we propose a cleaning device for gates in water conservancy projects. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a cleaning device for gates in water conservancy projects, which solves the technical problems in the background art mentioned above, and achieves the technical effect of cleaning rust and attachments on the screw rod, facilitating the rotation of the screw rod, and thus facilitating the lifting of the gate.

[0007] 2. Technical Solution

[0008] This application provides a cleaning device for a hydraulic engineering gate, comprising: a screw cleaning brush, a gate plate cleaning brush, and a screw flushing assembly. The screw cleaning brush is fixed on the gate frame and sleeved on a screw. The gate plate cleaning brush is fixed on the gate frame and placed on the water-facing side of the gate plate. The screw flushing assembly is fixed between the screw cleaning brush and the gate plate and placed on the water-facing side of the gate plate. The screw flushing assembly flushes the screw cleaning brush and the screw plate by pumping water.

[0009] As an optional solution to the technical solution of this application, the lead screw cleaning brush includes a sleeve and multiple bristles. The sleeve is coaxially sleeved on the lead screw and fixed to the gate frame. The multiple bristles are distributed in a ring and fixed to the inner wall of the sleeve. The inner diameter formed by the ring distribution of the bristles is smaller than the outer diameter of the lead screw.

[0010] As an optional solution to the technical solution of this application, the screw flushing assembly includes a water storage column and a piston and piston tube. The water storage column is fixed on the water-facing side of the gate, the piston is adapted to slide inside the water storage column, the piston tube is fixed on the piston and passes through the water storage column, the bottom of the piston has a water inlet hole communicating with the piston tube, and the bottom of the water storage column has multiple filter holes.

[0011] As an optional solution to the technical solution of this application, the multiple vertical filter holes are arranged in a row, and multiple rubber sheets are provided inside the water storage column. Each rubber sheet is placed on one side of each row of filter holes, and the upper end of the rubber sheet is fixedly connected to the inner wall of the water storage column.

[0012] As an optional solution to the technical solution in this application, the gate cleaning brush includes a fixed plate and two scrapers.

[0015] 3. Beneficial effects

[0016] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0017] 1. This application includes a lead screw cleaning brush, which cleans the rotating lead screw. Simultaneously, a gate cleaning brush cleans the water-facing surface of the gate. The lead screw cleaning brush is placed on the water-facing surface of the gate and can automatically replenish water when the water storage column is submerged in water. It also increases the pressure inside the lead screw flushing assembly when the gate rises, and flushes the cleaned lead screw through the lead screw flushing assembly to ensure the cleanliness of the lead screw's outer surface, reduce the friction coefficient between the lead screw and the gate frame, facilitate the rotation of the lead screw, and ultimately facilitate the lifting of the gate.

[0018] 2. This application uses a rubber sheet fixed to the inner wall of the water storage column at the upper end to block multiple filter holes in each vertical column. When the water storage column rises and the internal pressure increases, the rubber sheet can adhere to the inner wall of the water storage column to block the filter holes, thereby reducing the amount of water discharged from the filter holes in the water storage column, ensuring the water output of the piston tube, and ultimately improving the flushing effect on the lead screw.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-8As shown, this utility model provides a cleaning device for a hydraulic engineering gate, including: a screw cleaning brush 4, a gate plate cleaning brush 5, and a screw flushing assembly 6. The screw cleaning brush 4 is fixed on the gate frame 1 and sleeved on the screw 3. The gate plate cleaning brush 5 is fixed on the gate frame 1 and placed on the water-facing side of the gate plate 2. The screw flushing assembly 6 is fixed between the screw cleaning brush 4 and the gate plate 2 and placed on the water-facing side of the gate plate 2. The screw flushing assembly 6 flushes the screw cleaning brush 4 and the screw 3 after pumping water.

[0030] The gate plate 2 is slidably installed in the guide groove 11 of the gate frame 1. When the gate plate 2 intercepts the upstream, the screw flushing assembly 6 contains water, the screw 3 rotates counterclockwise and drives the gate plate 2 to rise, the screw cleaning brush 4 brushes the rotating screw 3, and at the same time the screw flushing assembly 6 compresses the internal solution and flushes between the screw cleaning brush 4 and the screw 3 to wash away the rust and microorganisms after brushing, so as to reduce the friction coefficient between the screw 3 and the gate frame 1. In addition, the gate cleaning brush 5 cleans the microorganisms on the water-facing surface of the gate plate 2 during the lifting process to ensure the cleanliness of the water-facing surface of the gate plate 2.

[0031] The lead screw cleaning brush 4 includes a sleeve 41 and multiple bristles 42. The sleeve 41 is coaxially sleeved on the lead screw 3 and fixed on the gate frame 1. The multiple bristles 42 are distributed in a ring and fixed on the inner wall of the sleeve 41. The inner diameter formed by the ring distribution of the bristles 42 is smaller than the outer diameter of the lead screw 3.

[0032] The sleeve 41 is fixed on the upper crossbeam of the gate frame 1 and is coaxially arranged with the lead screw 3. In this embodiment, the bristles 42 are preferably stainless steel wires. The inner diameter of the bristles 42 arranged in a ring is smaller than the outer diameter of the lead screw 3, so as to ensure that the inner end of the bristles 42 can abut against the thread of the lead screw 3, thereby improving the cleaning effect on the surface of the lead screw 3.

[0033] The screw flushing assembly 6 includes a water storage tube column 61, a piston 62, and a piston tube 63. The water storage tube column 61 is fixed on the water-facing side of the gate 2. The piston 62 is adapted to slide inside the water storage tube column 61. The piston tube 63 is fixed on the piston 62 and passes through the water storage tube column 61. The bottom of the piston 62 is provided with a water inlet hole 621 that communicates with the piston tube 63. The bottom of the water storage tube column 61 is provided with multiple filter holes 611.

[0034] The height of the water storage column 61 is the same as the height of the gate 2. When the gate 2 is fully lowered and abuts against the lower crossbeam of the gate frame 1, the upper surface of the piston 62 abuts against the inner wall of the water storage column 61. When the water storage column 61 is submerged in water, water seeps into the water storage column 61 through the filter hole 611. Under the principle of communicating vessels, the liquid surface in the water storage column 61 is coplanar with the upstream liquid surface. The diameter of the filter hole 611 is smaller than the diameter of the piston tube 63 and the inlet hole 621. The upper end of the piston tube 63 is through and fixed to the sleeve 41. Therefore, when the water storage column 61 rises, part of the water in the water storage column 61 is discharged through the filter hole 611. The other part is squeezed and sprayed into the sleeve 41 and the brush 42 through the inlet hole 621 and the piston tube 63 to rinse the rust and microorganisms in the sleeve 41 after cleaning.

[0035] Multiple vertical filter holes 611 are arranged in a row, and multiple rubber sheets 64 are installed inside the water storage column 61. Each rubber sheet 64 is placed on one side of each row of filter holes 611, and the upper end of the rubber sheet 64 is fixedly connected to the inner wall of the water storage column 61.

[0036] The upper end of the rubber sheet 64 is fixed to the inner wall of the water storage column 61 and can block the multiple filter holes 611 in each vertical column. Therefore, when the water storage column 61 is immersed in water, the rubber sheet 64 can bend inward under the action of water pressure, and the filter holes 611 can replenish water into the water storage column 61. When the water storage column 61 rises and the internal pressure increases, the rubber sheet 64 can stick to the inner wall of the water storage column 61 to block the filter holes 611, thereby reducing the large amount of water discharged from the filter holes 611 in the water storage column 61, ensuring the water output of the piston tube 63, and ultimately improving the flushing effect on the lead screw 3.

[0037] The gate cleaning brush 5 includes a fixed plate 51 and two scrapers 52. The fixed plate 51 is fixed on the water-facing side of the gate frame 1, and the two scrapers 52 abut against the gate 2 and are elastically connected to the fixed plate 51.

[0038] A guide rod 54 is symmetrically fixed on the side of the scraper 52 near the fixed plate 51. Multiple springs 53 are fixed between the fixed plate 51 and the scraper 52. The fixed plate 51 has a guide hole 511 that matches the guide rod 54.

[0039] The fixing plate 51 is horizontally fixed on the gate frame 1. The guide rod 54 is horizontally set and slidably inserted into the guide hole 511. Under the action of multiple springs 53, the scraper 52 can be attached to the water-facing side of the gate plate 2. When the gate plate 2 moves upward, the scraper 52 moves downward. At this time, under the action of the scraper 52, the microorganisms on the water-facing side of the gate plate 2 are cleaned.

[0040] It also includes two upslope blocks 21 and two downslope blocks 22. The two upslope blocks 21 are fixed on both sides of the upper edge of the gate plate 2, and the two downslope blocks 22 are fixed on both sides of the lower edge of the gate plate 2.

[0041] The two sides of the gate 2 and the upper and lower slope blocks 21 and 22 are slidably disposed in the two guide grooves 11. The slopes of the two upper slope blocks 21 are opposite each other, and the slopes of the two lower slope blocks 22 are opposite each other. The two upper slope blocks 21 are inclined downward and the two lower slope blocks 22 are inclined upward. Therefore, when the gate 2 rises, the silt and / or microorganisms in the guide grooves 11 opened on opposite sides of the gate frame 1 can be scraped out under the action of the two upper slope blocks 21. When the gate 2 falls, the lower slope blocks 22 fall and scrape out the silt and / or microorganisms in the guide grooves 11 to avoid a large accumulation that would cause the gate 2 to get stuck.

[0042] Working principle: When it is necessary to open the gate to release water, turn the handle on the lead screw 3 counterclockwise, so that the lead screw 3 drives the gate plate 2 to move upward along the guide groove 11. The bristles 42 fixed on the inner wall of the sleeve 41 clean the rotating lead screw 3. At the same time, the scraper 52 cleans the water-facing surface of the rising gate plate 2. Meanwhile, the water storage column 61 and the piston 62 move relative to each other. After the water in the water storage column 61 is pressurized, the rubber sheet 64 blocks the filter hole 611. The water in the water storage column 61 is pressurized and flows into the piston tube 63 through the water inlet hole 621. Finally, the pressurized water is sprayed onto the cleaned surface of the lead screw 3 through the piston tube 63 to wash away the rust and / or microorganisms cleaned by the bristles 42, so as to ensure the cleanliness of the surface of the lead screw 3 and ultimately reduce the friction coefficient between the lead screw 3 and the crossbeam on the gate frame 1.
