Description

Technical Field

[0001] This utility model relates to a hydraulic gate component, specifically a self-cleaning slide gate. Background Technology

[0002] Sluice gates, as important fluid control devices, are widely used in water conservancy, hydropower, municipal water supply and drainage, and industrial pipeline systems. They are typically made of carbon steel, stainless steel, or alloy materials, possessing excellent corrosion resistance and mechanical strength, and can adapt to complex environments such as underwater, humid, and silty conditions. They maintain stable performance under high or low temperature conditions, making them particularly suitable for scenarios requiring frequent opening and closing. Through the linear movement of the gate plate and its tight fit with the frame, they completely cut off water flow or material transport, providing excellent sealing and low operating resistance. Manual, electric, or hydraulic drive methods ensure flexible and reliable operation. They are used to cut off or regulate media flow, such as precisely controlling water levels during reservoir flood discharge, isolating different process units in sewage treatment, or preventing backflow in chemical production.

[0003] In the prior art, 01720811219.9 describes a gate valve. This utility model discloses a gate valve, the key technical points of which include a valve frame, a valve, a valve stem, and a driving device. The valve frame has a valve port for valve sliding. One end of the valve stem is connected to the upper side of the valve, and the other end protrudes from the upper wall of the valve frame. The driving device is fixed to the upper side of the valve frame and connected to the valve stem, used to drive the valve to open or close. The inner walls on both sides of the valve port have receiving grooves. A support plate is hinged in the receiving groove to support the bottom surface of the valve when it is open. An elastic element is provided between the inner wall of the support plate and the side wall of the valve port to drive the support plate to flip away from the receiving groove. This utility model has the effect of extending the valve stem's lifespan.

[0004] Existing gate valves cannot effectively self-clean their inner walls, making them prone to contamination with moss and other pollutants when exposed to polluted water. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a self-cleaning gate.

[0006] This utility model is achieved using the following technical solution: a self-cleaning gate valve, comprising a gate body, a top mounting platform on the gate body, a connecting screw on the top mounting platform, the connecting screw having external threads, a manual turntable on the top of the connecting screw, the manual turntable and the connecting screw being fixed together by welding, a mounting bracket on the gate body, a top bracket on the mounting bracket, a screw fixing platform on the top bracket, a threaded hole on the screw fixing platform, the connecting screw being fitted into the threaded hole, a self-cleaning component between the gate body and the mounting bracket, the self-cleaning component being a cleaning brush plate, the cleaning brush plate being located inside the mounting bracket, the cleaning brush plate having an outer surface, the outer surface being covered with fine bristles.

[0007] The gate body is provided with sealing components on both sides. The sealing components are sealing rubber rings, which are fixed to the side of the gate by rivets.

[0008] The mounting bracket is provided with an upper gap and a lower gap, both of which are rectangular gaps. A liquid channel space pipe is provided on the lower gap.

[0009] The liquid channel space pipe provided on the lower gap is equipped with a block impurity separating component. The block impurity separating component is a material blocking component used to separate impurities. The material blocking component is equipped with multiple material blocking rods.

[0010] The material-blocking component is provided with a base plate, which is fixed to the lower gap by bolts, and a plurality of material-blocking thin rods are evenly arranged on the base plate.

[0011] A liquid passage gap is provided between the baffle rods, and a fine screen is provided between the baffle rods, with multiple fine mesh holes on the fine screen.

[0012] Compared to existing technologies, the top mounting platform and threaded connecting screw on the top of the gate body of this utility model allow for easy and labor-saving operation through the cooperation of the manual turntable and the connecting screw. For convenient and regular cleaning of moss and other deposits on the inner wall of the gate, a cleaning brush plate can be used for self-cleaning. When the gate is raised or lowered, the fine bristles on the cleaning brush plate automatically scrape away moss and other deposits attached to the inner side of the mounting bracket, effectively preventing the accumulation of impurities from affecting the sealing performance. The lower section integrates the liquid channel space and separates blocky impurities. Multiple baffle rods fixed to the base plate, combined with a fine mesh screen structure, allow for smooth fluid flow while intercepting larger solid debris, preventing pipe blockage. The fine mesh further filters small particles, achieving graded filtration of the gate. Attached Figure Description
