The filtration mechanism includes a filter cylinder, which is fixedly installed at the bottom of a support set inside the ditch body and is located on the water-facing side of the gate body. The top arc surface of the filter cylinder is provided with a placement groove, and a filter core is movably installed inside the placement groove. The filter core has a recess inside, and a primary filter screen for filtering large impurities and a secondary filter screen for filtering silt are respectively installed inside the recess. The primary filter screen faces the water-facing side inside the ditch. The filter core is equipped with a cleaning component for scraping and cleaning the sludge on the surface of the secondary filter screen.

[0006] In one embodiment, the cleaning assembly includes a scraper and a drive module, the scraper being connected to the drive module, and the end sidewall of the scraper being slidably connected to the sidewall of the secondary filter.

[0007] In one embodiment, the scraper is provided with bristles on the sidewall facing the secondary filter.

[0008] In one embodiment, the drive module includes a mounting box, which is fixedly installed inside the recess. A side bevel gear is provided inside the mounting box. The central end of the scraper passes through the side wall of the mounting box and is connected to the side wall of the side bevel gear. A top bevel gear is meshed with the top of the side bevel gear. The top end of the top bevel gear is connected to the bottom end of a connecting rod. The connecting rod passes through the top end of the filter core and the bracket and is connected to a rotating handle.

[0009] In one embodiment, the bottom arc surface of the filter core is provided with a plurality of mud leakage holes, and the inner arc surface of the filter cylinder is provided with mud discharge holes corresponding to the mud leakage holes, the mud discharge holes being inserted into the inside of the mud leakage holes.

[0013] Beneficial effects 1. The above-mentioned diversion ditch valve has a filter mechanism installed on the water-facing side of the gate body. The filter core is adjustable inside the filter cylinder. The inner cavity of the filter core has a primary filter screen and a secondary filter screen. The primary filter screen filters out larger impurities in the ditch water, and the secondary filter screen filters out silt. The double filtration prevents silt from adhering to the water-facing side wall of the gate plate inside the gate body and entering the gate body with the gate plate, thus affecting the raising and lowering of the gate plate. 2. The above-mentioned drainage ditch valve has a cleaning component inside the filter core for scraping and cleaning the sludge on the surface of the secondary filter screen.

[0018] The following is combined with Figures 1-5 This utility model describes a diversion ditch valve for water conservancy construction management.

[0019] In one embodiment, a diversion ditch valve for water conservancy construction management includes: a ditch body 100 and a gate body 200, which are installed inside the ditch body 100; Additional note: The gate body 200 in this application can be of the QZM series channel gate model; The filtration mechanism 300 is installed on the water-facing side of the gate body 200 and is used to filter impurities in the ditch water. The filtration mechanism 300 includes a filter cylinder 301, which is fixedly installed at the bottom of the support 201 inside the ditch body 100 and is located on the water-facing side of the gate body 200. The top arc surface of the filter cylinder 301 is provided with a placement groove 304, and a filter core 303 is movably installed inside the placement groove 304. In this embodiment, the filter core 303 is movably disposed inside the placement groove 304 opened on the top arc surface of the filter cylinder 301, so that the filter core 303 can be lifted up for cleaning and maintenance by maintenance personnel. The filter cylinder 301 and the ditch body 100 can be installed by welding, bolting or other reliable fixing methods to ensure its stability under the impact of flowing water. like Figure 2 and Figure 3 As shown, the filter core 303 has a recess 305 inside, and a primary filter screen 302 for filtering large impurities and a secondary filter screen 306 for filtering silt are respectively installed inside the recess 305. The primary filter screen 302 faces the water-facing side inside the ditch. The primary filter screen 302 and the secondary filter screen 306 are made of nylon material with rust-proof and corrosion-resistant properties. The filter core 303 is equipped with a cleaning component for scraping and cleaning the silt on the surface of the secondary filter screen 306. In this embodiment, a primary filter screen 302 and a secondary filter screen 306 are respectively installed inside the recess 305 opened inside the filter core 303. The primary filter screen 302 has larger mesh and is mainly used to intercept large suspended objects such as aquatic plants, stones, and branches in the ditch water to prevent them from directly impacting the gate. The secondary filter screen 306 has finer mesh and is located after the primary filter screen 302. It is used to filter fine silt and mud in the water. The primary filter screen 302 and the secondary filter screen 306 are made of nylon material, which is not only rust-proof and corrosion-resistant, but also has a certain toughness and strength, and can adapt to the complex water quality environment in water conservancy construction. like Figure 3 As shown, the cleaning assembly includes a scraper 307 and a drive module. The scraper 307 is connected to the drive module. The end sidewall of the scraper 307 is slidably connected to the sidewall of the secondary filter 306. The scraper 307 is provided with bristles 315 facing the sidewall of the secondary filter 306. In this embodiment, the scraper 307 is made of engineering plastic or rubber material with certain hardness and wear resistance. Its edge shape matches the curved surface of the secondary filter screen 306. The end of the scraper 307 is slidably connected to the side wall of the secondary filter screen 306, so that the scraper 307 scrapes and cleans the sludge on the side wall of the secondary filter screen 306. The side wall of the scraper 307 is provided with bristles 315, which can be made of soft and durable materials such as nylon, which can penetrate into the mesh and remove the tightly attached sludge, further improving the sludge removal effect. like Figure 3 As shown, the drive module includes a mounting box 308, which is fixedly installed inside the recess 305. A side bevel gear 310 is provided inside the mounting box 308. The central end of the scraper 307 passes through the side wall of the mounting box 308 and is connected to the side wall of the side bevel gear 310. A top bevel gear 311 is meshed with the top of the side bevel gear 310. The top end of the top bevel gear 311 is connected to the bottom end of the connecting rod 312. The connecting rod 312 passes through the filter core 303 and the top end of the bracket 201 and is connected to the rotating handle 313. In this embodiment, the side bevel gear 310 and the top bevel gear 311 are disposed inside the mounting box 308. The mounting box 308 provides a sealed and stable installation environment for the side bevel gear 310 and the top bevel gear 311, preventing water and impurities from entering and affecting the gear transmission. The transmission method of the side bevel gear 310 and the top bevel gear 311 can efficiently convert the vertical rotation of the operator rotating the handle 313 on the ground into the rotational motion of the scraper 307 in the horizontal plane, thereby driving the scraper 307 to scrape and clean the sludge on the side wall of the secondary filter screen 306. like Figure 5 As shown, the bottom arc surface of the filter core 303 is provided with multiple mud leakage holes 316, and the inner arc surface of the filter cylinder 301 is provided with mud discharge holes 317 corresponding to the mud leakage holes 316. The mud discharge holes 317 are inserted into the inside of the mud leakage holes 316. The bottom arc surface of the filter core 303 is provided with mud squeezing columns 318 between the multiple mud leakage holes 316, and the inner arc surface of the filter cylinder 301 is provided with column insertion holes 309 between the multiple mud discharge holes 317. The mud squeezing columns 318 are inserted into the inside of the column insertion holes 309. In this embodiment, after the scraper 307 scrapes the sludge off the secondary filter screen 306, the sludge falls to the bottom of the filter core 303 under the action of gravity and is discharged through the sludge leakage hole 316 opened on the bottom arc surface of the filter core 303 and the sludge discharge hole 317 opened on the bottom arc surface of the filter cylinder 301. When the filter core 303 is raised and lowered under the action of the pneumatic telescopic rod 314, the sludge squeezing column 318 is inserted into the column insertion hole 309, which can squeeze the sludge accumulated near the sludge leakage hole 316, prevent the sludge from blocking the sludge discharge channel, and ensure that the sludge can be discharged smoothly through the sludge discharge hole 317 and out of the gate body 200. like Figure 2 and Figure 3 As shown, a pneumatic telescopic rod 314 is provided on the top surface of the bracket 201. The pneumatic telescopic rod 314 is located on both sides of the rotating handle 313. The working end of the pneumatic telescopic rod 314 passes through the top surface of the bracket 201 and connects to the top surface of the filter core 303. In this embodiment, when the primary filter screen 302 and the secondary filter screen 306 need to be cleaned, the primary filter screen 302 is set to be detachable and retracted through the working end of the pneumatic telescopic rod 314, thereby driving the filter core 303 to rise, so that the filter core 303 rises above the water surface of the ditch, and cleans the impurities on the side walls of the primary filter screen 302 and the secondary filter screen 306 inside the filter core 303; Working principle: Under normal filtration conditions, the water flow in the ditch first impacts the primary filter screen 302, where large impurities are intercepted. The water then passes through the secondary filter screen 306, where fine silt is filtered out. The relatively clean water that has undergone double filtration flows to the gate body 200, effectively preventing impurities and silt from accumulating on the water-facing side of the gate. When it is necessary to clean the silt attached to the secondary filter screen 306, the operator can rotate the handle 313 at the side of the channel. The rotation of the handle is transmitted to the top bevel gear 311 through the connecting rod 312, which drives the side bevel gear disk 310 that meshes with it to rotate, thereby driving the scraper 307 to rotate on the surface of the secondary filter screen 306. The bristles 315 on the scraper 307 help to remove the stubborn silt in the mesh. The scraped silt is discharged through the mud leakage hole 316 and the mud discharge hole 317 under the action of gravity. During this process, the pneumatic telescopic rod 314 can be activated in a timely manner to make the filter core 303 rise and fall slightly. The mud squeezing column 318 and the insertion column hole 309 are disengaged from the mud leakage hole 316 and the mud discharge hole 317 to ensure that the sludge is discharged smoothly through the mud leakage hole 316 and the mud discharge hole 317.

[0020] It should be noted that the pneumatic telescopic rod 314 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the pneumatic telescopic rod 314 can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0021] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
