Description

Technical Field

[0001] This utility model relates to the field of river water conservancy gate technology, and in particular to a river water conservancy gate interception filter screen. Background Technology

[0002] In river water conservancy projects, sluice gates play a vital role in controlling water flow, regulating water levels, and preventing foreign objects from entering specific water areas. Meanwhile, the accompanying interception and filtration screens are a crucial line of defense for ensuring the normal operation of water conservancy facilities and the stability of the aquatic ecological environment. Over time, the types and quantities of pollutants in rivers increase. Large amounts of floating debris, including various types of garbage, aquatic plant remains, and oil slicks, flow towards the sluice gates with the water flow. If this floating debris is not cleaned up in time, it will cause various forms of damage to the sluice gates and related water conservancy facilities. On the one hand, the floating debris accumulating on the outer surface of the filter screen increases water flow resistance, leading to increased water pressure on the sluice gate, accelerating the wear and aging of the gate and its auxiliary structures, shortening their service life, and increasing maintenance costs and frequency. On the other hand, some floating debris may carry bacteria, parasites, or harmful substances, which, if attached to the filter screen surface for a long time, may breed and multiply in suitable environments, polluting the surrounding water bodies, disrupting the balance of the aquatic ecosystem, and affecting the survival and reproduction of aquatic organisms.

[0003] Existing interception filters only focus on the initial blocking of floating objects, lacking an effective salvage and cleaning mechanism. In practice, workers often need to use specialized salvage boats or tools to approach the filter for manual salvage operations. This method is not only inefficient and consumes a lot of manpower, material resources, and time, but also extremely difficult to carry out salvage operations in some river areas with rapid currents, wide water surfaces, or complex environments. It may even endanger the personal safety of workers due to the inconvenience of operation. Therefore, there is a problem of inconvenience in salvaging floating objects. Utility Model Content

[0021] 2. Start the second reduction motor. The output shaft of the second reduction motor drives the threaded rod to rotate. The rotation of the threaded rod causes the connecting plate and the cleaning plate to slide. The cleaning plate slides on the outer surface of the salvage frame, which allows the floating objects on the outer surface of the salvage frame to enter the transport pipe.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a river water conservancy gate interception filter screen, including a gate body 1. A retrieval mechanism 2 and a cleaning mechanism 3 are fixedly connected to the outer surface of the gate body 1. The retrieval mechanism 2 includes a support plate 203 fixedly connected to the outer surface of the gate body 1. A drum 204 is rotatably connected to the outer surface of the support plate 203. A rope 201 is fixedly connected to the outer surface of the drum 204. The other end of the rope 201 is fixedly connected to a retrieval frame 207.

[0031] The specific salvage mechanism 2 also includes a filter plate 208 fixedly connected to the inner side of the sluice gate body 1, and the outer surface of the salvage frame 207 is slidably connected to the inner side of the sluice gate body 1. A limit rod 209 is fixedly connected to the inner wall of the sluice gate body 1, and the outer surface of the limit rod 209 is slidably connected to the outer surface of the salvage frame 207. The filter plate 208 is fixedly connected to the inner wall of the sluice gate body 1, and the outer surface of the salvage frame 207 is slidably connected to the outer surface of the filter plate 208. A first reduction motor 202 is fixedly connected to the upper surface of the sluice gate body 1. The output shaft of the first reduction motor 202 is fixedly connected to the outer surface of the drum 204. A rotating shaft 205 is fixedly connected to the outer surface of the drum 204. The outer surface of the rotating shaft 205 is rotatably connected to the outer surface of the support plate 203. A groove 206 is provided on the outer surface of the sluice gate body 1. The sluice gate body 1 includes a mounting frame, a gate plate, a hoist, a water-stop rubber, a gate slot, a gate pier, etc. The salvage mechanism 2 and the cleaning mechanism 3 are both installed on the outer surface of the mounting frame.

[0032] The first reduction motor 202 is then activated. The output shaft of the first reduction motor 202 drives the drum 204 and the rotating shaft 205 to rotate, thereby enabling the drum 204 to wind up and unwind the rope 201, allowing the salvage frame 207 to slide along the outer surface of the limiting rod 209, thus facilitating the salvage of floating objects on the outer surface of the filter plate 208.

[0033] Example 2

[0034] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The cleaning mechanism 3 includes a fixing plate 307 fixedly connected to the outer surface of the sluice gate body 1. Two sets of transport pipes 306 are fixedly connected to the lower surface of the fixing plate 307, and a cleaning plate 305 is slidably connected to the lower surface of the fixing plate 307.

[0035] Specifically, a second reduction motor 301 is fixedly connected to the upper surface of the fixing plate 307, a fixing block 302 is fixedly connected to the upper surface of the fixing plate 307, a threaded rod 303 is rotatably connected to the outer surface of the fixing block 302, the other end of the threaded rod 303 is fixedly connected to the output shaft of the second reduction motor 301, and a connecting plate 304 is threadedly connected to the outer surface of the threaded rod 303. The outer surface of the connecting plate 304 is fixedly connected to the outer surface of the cleaning plate 305.

[0036] The second reduction motor 301 is then activated. The output shaft of the second reduction motor 301 drives the threaded rod 303 to rotate. The rotation of the threaded rod 303 causes the connecting plate 304 and the cleaning plate 305 to slide. The cleaning plate 305 slides on the outer surface of the salvage frame 207, allowing the floating objects on the outer surface of the salvage frame 207 to enter the transport pipe 306. The transport pipe 306 facilitates the introduction of the floating objects into the river channel. The salvage frame 207 slides on the outer surface of the filter plate 208, which facilitates the sweeping off of the floating objects adsorbed on the outer surface of the filter plate 208, and facilitates the cleaning of the outer surfaces of the salvage frame 207 and the filter plate 208.

[0037] Working principle: The filter plate 208 and the retrieval frame 207 facilitate the filtration of impurities in the water flow, causing floating objects to be intercepted on the outer surface of the filter plate 208. Then, the first reduction motor 202 is activated. The output shaft of the first reduction motor 202 drives the drum 204 and the rotating shaft 205 to rotate, thereby allowing the drum 204 to reel in and out the rope 201. This allows the retrieval frame 207 to slide along the outer surface of the limiting rod 209, facilitating the retrieval of floating objects on the outer surface of the filter plate 208. This ensures that the upper surface of the retrieval frame 207 and the lower surface of the fixing plate 307 are in contact. Then, the second reduction motor 301 is started. The output shaft of the second reduction motor 301 drives the threaded rod 303 to rotate. The rotation of the threaded rod 303 causes the connecting plate 304 and the cleaning plate 305 to slide. The cleaning plate 305 slides on the outer surface of the salvage frame 207, thereby allowing the floating objects on the outer surface of the salvage frame 207 to enter the transport pipe 306. The transport pipe 306 facilitates the introduction of the floating objects into the river channel. The salvage frame 207 slides on the outer surface of the filter plate 208, which facilitates the sweeping off of the floating objects adsorbed on the outer surface of the filter plate 208, and facilitates the cleaning of the outer surfaces of the salvage frame 207 and the filter plate 208.
