Description

Technical Field

[0001] The invention relates to the technical field of water conservancy gates, and in particular to a flood control gate for a water conservancy project. Background Art

[0002] The gate is a key component of hydraulic structures. It controls the opening and closing of waterways and has the functions of intercepting flow, regulating water levels, regulating flow, and discharging sediment and floating objects. As an important water conservancy facility, flood control gates are usually installed at the entrances and exits of rivers, reservoirs, and channels. The gates are opened and closed by the opening and closing mechanism to control the water flow. It can effectively intercept sediment and prevent it from entering the downstream, and discharge sediment after the flood recedes to ensure the smooth flow of the river, playing an important role in flood control and sediment discharge.

[0003] The Chinese invention patent with patent number CN114808872B discloses a flood control gate for a water conservancy project, including a gate, a concrete layer is poured on the riverbed where the gate is located, gate piers are arranged on both sides of the gate, a gate beam is arranged on the top of the gate pier, a filter plate is arranged on the concrete layer, gate piers are arranged on both sides of the filter plate, gate beams are arranged on the top of the gate piers, scrapers are slidably installed on the relative inner sides of the two gate beams, and the scrapers and the filter plates are fitted with each other; the invention drives the scraper to move along the surface of the filter plate by a motor, so that foreign matter such as garbage and water plants on the surface of the filter plate can be removed from the filter plate, thereby improving the flow capacity of the filter plate; foreign matter in the water body between the gate and the filter plate is salvaged out of the water body by a collection frame, so as to facilitate the removal of foreign matter in the water body in this area, which has the effect of reducing foreign matter attached to the filter plate.

[0004] Although the above scheme improves the working efficiency to a certain extent when cleaning the filter plate, in actual use, since the scraper structure is relatively simple and the filter plate can only be cleaned once in a single movement, when a large piece of debris blocks the filter plate and hinders the continued movement of the scraper, the hard collision between the scraper and the debris may cause damage to the surface of the filter plate, making it impossible to remove foreign matter on the filter plate in time. At the same time, it is not suitable for filter plates with different deformations, and there are cleaning dead corners. It is also unable to adapt to the removal of foreign matter of different thicknesses and hardnesses, and cannot meet different cleaning needs. The scope of application is low and the cleaning efficiency is reduced. It may also affect the drainage function of the water conservancy project and may even cause safety accidents.

[0059] Embodiment 2: In order to further improve the cleaning effect of the filter plate 150 and make the cleaning operation more flexible, the present application proposes the following technical solutions for the above technical problems, specifically:

[0060] like Figures 5 to 8 As shown, the cleaning unit 300 further includes an adjusting assembly 340 for adjusting the angle between the scraper assembly 330 and the filter plate 150 .

[0061] The adjustment assembly 340 includes a gear ring 341, a rotating gear 342 and a movable rack 343;

[0062] The toothed rings 341 are provided with two, corresponding to the fixed posts 320 one by one, and are respectively slidably connected to the corresponding fixed posts 320, and are used to adjust the inclination angles of the scraper 1 331, the scraper 2 332 and the scraper 3 333 by rotating themselves;

[0063] The rotating gears 342 are provided with two, arranged front and rear, and are respectively rotatably connected in the corresponding fixing columns 320 and meshed with the corresponding gear rings 341 to drive the gear rings 341 to rotate;

[0064] The movable rack 343 is placed vertically and fixed on the movable block 310 through the connecting plate 311. The movable rack 343 is also slidably connected to the gate pier 2 130 located at the front side through the slider 1 3431 and meshes with the rotating gear 342 located at the front.

[0065] A slide rail 3432 is fixed to the inner side of the front end of the moving block 310, and the moving rack 343 is slidably connected in the slide rail 3432 through an electric slider 3433. The electric slider 3433 is used to drive the moving rack 343 to move and drive the rotating gear 342 and the gear ring 341 to rotate at an angle.

[0066] The present application drives the moving rack 343 to move through the electric slider 3433, which in turn drives the rotating gear 342 to rotate, and finally causes the gear ring 341 to rotate at an angle. This series of mechanical linkage designs enables the scraper 1 331, the scraper 2 332 and the scraper 3 333 to flexibly adjust the angle between them and the filter plate 150, and cooperate with the torsion spring to exert an action on each scraper, so that the present device can flexibly change the cleaning force of the scraper assembly 330 on the surface of the filter plate 150 according to the actual cleaning needs and environmental conditions, further improving the cleaning effect.

[0067] By precisely controlling the angles between scraper 1 331, scraper 2 332, scraper 3 333 and the filter plate 150, it can be ensured that the scraper assembly 330 can more effectively remove foreign matter on the filter plate 150, especially stubborn foreign matter on the filter plate 150 or foreign matter in tiny gaps. By adjusting the angle and strength of the scraper assembly 330, they can be more easily removed, thereby improving the operating efficiency and safety of the entire water conservancy project, and helping to reduce the wear and failure rate of the equipment during long-term use, thereby extending the service life of the equipment and reducing maintenance costs.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
