Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering gate plates, in particular to a water conservancy engineering gate plate with a debris filtering function used in water conservancy engineering. Background Art

[0002] The gate plate is a major component in water conservancy projects, and its main function is to block water flow, regulate water level, and control flow rate. In water conservancy projects, the water flow is usually mixed with a lot of impurities, such as branches, plastic bags, plastic bottles and other lightweight foreign objects. In order to prevent foreign objects from polluting the downstream environment, it is necessary to intercept and filter the foreign objects in the water flow. In traditional technology, the filter screen is mainly used to intercept foreign objects and impurities. However, the filter screen is easily clogged by foreign objects during filtration, which affects the passage of water and requires cleaning of the filter screen.

[0003] At present, the impurities filtered by the filter screen are cleaned by the hydraulic engineering gate plate during use mainly by cleaning the filter screen surface with a roller brush to achieve the function of cleaning the filter screen. For example, a patent with the announcement number CN221702313U discloses a hydraulic engineering gate plate with a filtering function, which is provided with a sealing plate and a filter plate inside the gate plate to cooperate as a water flow sealing and filtering structure, and can synchronously open the sealing plate and the filter plate to fully open the gate, and utilizes the gear on the bottom side of the sealing plate meshing with the external rack to drive the bottom shaft to rotate, and the bristles densely distributed on the outside of the bottom shaft clean the front side of the filter plate to remove impurities. In order to remove the accumulated impurities that clog the pores on the surface of the filter plate and ensure the smooth flow of water through the filter plate, the existing hydraulic engineering gate plate can only remove smaller impurities when in use, and lightweight foreign matter such as plastic bags will be firmly squeezed on the filter plate under the action of water pressure, making them difficult to remove. Moreover, the sealing plate is difficult to close due to the obstruction of the debris, thereby losing its interception function. At the same time, it is impossible to collect the foreign matter that has fallen after filtering and cleaning, and the debris will accumulate under the sealing plate, thereby affecting the sealing effect when the sealing plate is closed. Therefore, in response to the above problems, a hydraulic engineering gate plate with a filtering function for hydraulic engineering is proposed. Summary of the Invention

[0004] In order to make up for the shortcomings of the existing technology, the present invention proposes a water conservancy project gate plate with a filtering function for water conservancy projects, in view of the problem that the roller brush in the existing technology can only brush away smaller impurities when used, and lightweight foreign matter will be firmly squeezed on the filter plate under the action of water pressure and thus difficult to remove, and the foreign matter dropped by filtration and cleaning cannot be collected, and the debris will accumulate under the sealing plate, thereby affecting the sealing effect when the sealing plate is closed.

[0022] like Figure 4 and Figure 5 In the embodiment, the separation component 3 also includes an inner spline sleeve 35 rotatably mounted in the two drive grooves 22, and a spline shaft 36 is slidably provided in the two inner spline sleeves 35, and the two spline shafts 36 are rotatably mounted on the upper part of the two side plates 11, and a No. 2 motor 323 is fixed on the outer side of the two side plates 11, and the output end of the No. 2 motor 323 is connected to the top of the spline shaft 36 through a gear.

In the initial state, the springs 322 will always push the baffles 321 toward the side of the support frame 310 to retract the connecting rods 320 into the fixed sleeve 318, so as to drive the side of the scraper 311 to abut against the outer wall of the separation cylinder 31, so as to scrape and collect the impurities adsorbed on the outer wall of the separation cylinder 31.

[0024] like Figure 5and Figure 6 In the embodiment, the support frame 310 is fixedly connected between the lifting plates 21 in the two lifting assemblies 2, and the outer curved surfaces of the two separation cylinders 31 are provided with evenly distributed sinking grooves 39.

[0025] like Figure 3 、 Figure 5 and Figure 7 In the figure, the filter collection assembly 4 includes two fixed tubes 41 fixed on the valve seat 1, and the two fixed tubes 41 are located on the side of the positioning cylinder 32 facing the water baffle 12, and a rotating tube 42 is rotatably installed in the port between the two fixed tubes 41, and a No. 1 inner tube 43 connected to it is fixedly connected to the rotating tube 42, and an outer sleeve 44 is slidingly provided on the outside of the port of the No. 1 inner tube 43, and a No. 2 inner tube 45 is slidingly provided in the port of the outer sleeve 44 opposite to the fixed tube 41, and the No. 2 inner tube 45 is fixedly connected to the side curved surface of the positioning cylinder 32 and is connected thereto, and the outer sleeve 44 is driven to slide and retract outside the ports of the No. 2 inner tube 45 and the No. 1 inner tube 43 when the positioning cylinder 32 is raised and lowered to maintain the communication effect between the positioning cylinder 32 and the two fixed tubes 41, so as to perform secondary filtration on the water flow.

[0026] like Figure 3 、 Figure 7 and Figure 9In the embodiment, the two fixed pipes 41 are fixedly connected to the side curved surfaces of the drainage chambers 46 connected thereto, and the two drainage chambers 46 are arranged through the side of the water baffle 12, and the two drainage chambers 46 are fixedly connected to the ports of the two drainage chambers 46. The closed pipes 47 are provided with filter holes 48 on the side curved surfaces facing the openings of the two drainage chambers 46. The closed pipes 47 are respectively rotatably installed with auger 416 at both ends, and the rotation trajectory of the auger 416 is in contact with the inner wall of the closed pipe 47. A No. 3 motor 419 is fixed on the closed pipe 47, and the No. 3 motor 419 is rotated. The output end is arranged through the closed tube 47 and is connected to the central axis of the two augers 416 through gears. The lower part of the closed tube 47 is located between the two drainage bins 46 and is fixedly connected to a collecting bin 417 communicated with it. A filter residue frame 418 is provided in the side opening of the collecting bin 417, and the filter residue frame 418 can be fastened in the collecting bin 417 by bolts. Water is used to flow through the filter holes 48 for filtering and removing impurities, and under the rotation of the augers 416, the intercepted impurities are transported to the filter residue frame 418 for collection to prevent the impurities from clogging the filter holes 48 and affecting the drainage effect.

[0027] like Figure 7 、 Figure 8 and Figure 9 In the figure, a closing bin 49 is provided on each of the two drainage bins 46, and a closing plate 410 is slidably provided in the upper opening of the closing bin 49, and a connecting beam 411 is fixedly connected to the two closing plates 410, and a threaded sleeve 413 is fixed through the connecting beam 411, and a No. 2 screw 414 is threadedly connected to the threaded sleeve 413, and a fixed beam 412 is fixed between the two drainage bins 46, and the bottom end of the No. 2 screw 414 is rotatably installed on the fixed beam 412, and a turntable 415 is fixed to the top of the No. 2 screw 414, which drives the two closing plates 410 to rise and fall in the closing bin 49 when the No. 2 screw 414 rotates, so as to control the opening size of the drainage bin 46, thereby being able to control the water flow size and the opening and closing of the gate.

[0028] like Figure 2 and Figure 3 In the figure, the driving assembly 5 includes a fixed frame 51 fixed on the upper part of the water baffle 12, and a driving rod 52 is rotatably provided on the fixed frame 51. The two ends of the driving rod 52 are respectively connected to the top of the No. 1 screw 24 in the frame lifting assembly 2 through gears. A No. 4 motor 53 is fixed on the fixed frame 51, and the output end of the No. 4 motor 53 is connected to the driving rod 52 through gears. The No. 4 motor 53 is used for driving, and the No. 1 screw 24 is rotated under the transmission action of the driving rod 52 to realize the driving effect on the lifting assembly 2.

[0029] During operation, the roller brush of the existing hydraulic engineering gate can only brush away smaller impurities when in use, while lightweight foreign matter such as plastic bags will be firmly squeezed on the filter plate under the action of water pressure, making it difficult to remove, and the sealing plate is also difficult to close due to the obstruction of the debris, thereby losing the interception function, and at the same time, it is impossible to collect the foreign matter that has been filtered and cleaned, and the debris will accumulate under the sealing plate, thereby affecting the sealing effect when the sealing plate is closed. In this solution, by controlling the No. 4 motor 53 to drive, the No. 4 motor 53 drives the No. 1 screw 24 in the two lifting assemblies 2 through the driving rod 52, and under the action of the No. 1 screw 24 being threadedly connected to the threaded hole 23, the No. 1 screw 24 drives the lifting plate 21 to slide and rise in the telescopic slot 13 when it rotates; At the same time, when the two lifting plates 21 are lifted and lowered, the two separation cylinders 31 and the support frame 310 will be driven to move up and down. Driven by the two separation cylinders 31, the positioning cylinder 32 will also move with it, and when the positioning cylinder 32 moves, the second inner tube 45 will be telescopically slid in the outer sleeve 44, and the outer sleeve 44 will be telescopically slid outside the first inner tube 43 to maintain the connection between the rotating tube 42 and the positioning cylinder 32, and the rotating tube 42 will rotate between the two fixed tubes 41, so that the upper sides of the two separation cylinders 31 are partially exposed to the water surface, and the support frame 310 is located on the water surface, and the control The two No. 1 motors 37 are in operation. When the No. 1 motor 37 is in operation, it drives the spline shaft 36 to rotate, and drives the inner spline sleeve 35 to rotate through the spline shaft 36. When the inner spline sleeve 35 rotates, it drives the gear ring 34 to drive the rotating shaft 33 to rotate on the side of the lifting plate 21, and drives the separation cylinder 31 to rotate through the rotating shaft 33. When the separation cylinder 31 rotates, it drives the cutting blade 38 on its surface to rotate around its outer side. In the process of raising and lowering the lifting plate 21, the spline shaft 36 will extend and slide in the inner spline sleeve 35 to ensure the driving effect on the rotating shaft 33. Then the closing plate 410 can be opened by rotating the turntable 415. When the turntable 415 rotates, it drives the No. 2 screw 414 to rotate. When the No. 2 screw 414 rotates, it drives the connecting beam 411 to rise and fall under the action of the threaded connection with the threaded sleeve 413, and when the connecting beam 411 rises and falls, it drives the closing plate 410 to rise and fall in the closing chamber 49. At this time, the drainage chamber 46 can be opened through the closing plate 410. At this time, the upstream water will enter it through the through holes on the surface of the separation cylinder 31, and under the action of the flow of water, the light debris on the water surface will be squeezed and adsorbed on the surface of the separation cylinder 31, and as the separation cylinder 31 rotates, the cutting blade 38 will also hook up the light debris on the water surface and transport it to the scraper 311. As the separation cylinder 31 continues to rotate, the debris hooked up by the cutting blade 38 and the debris adsorbed on the surface of the separation cylinder 31 The attached debris will be scraped off by the side of the scraper 311, so that light debris can be collected. The vibration motor 316 is controlled to operate, and the scraper 311 will vibrate during operation. The debris falling on the scraper 311 will be blocked by the blocking blade 314. At the same time, because the rotation trajectory of the cutting blade 38 passes through the rotating groove 312, the cutting blade 38 will cut the debris on the scraper 311 and blocked by the blocking blade 314 during the rotation process. The plastic bag and other debris hooked on the cutting blade 38 will be cut by the shear force between the fixed blade 313 and the cutting blade 38. The cut debris will slide into the collecting groove 317 due to the vibration of the scraper 311 and be collected, thereby achieving the effect of collecting light debris, so as to prevent light debris from clogging the gate and affecting the water flow. The water entering the two separation cylinders 31 will enter the positioning cylinder 32, and enter the rotating tube 42 through the No. 2 inner tube 45, the outer sleeve 44 and the No. 1 inner tube 43, and then enter the two drainage bins 46 through the two fixed tubes 41, and then enter the closed tube 47, and finally be discharged through the filter hole 48. At this time, the water will be filtered twice when passing through the filter hole 48 to intercept smaller impurities in the water to prevent impurities in the upstream water from entering the downstream and causing pollution, and the impurities will remain in the closed tube 47, and cooperate with the control of the No. 3 motor 419 to operate. When the No. 3 motor 419 is running, it will drive the two screw dragons 416. When the screw dragon 416 rotates, it will scrape off the impurities filtered by the filter hole 48 and transport them to the collection bin 417. The transported impurities will enter the filter residue frame 418 for temporary storage, thereby completing the secondary filtration of the water flow. The combination achieves the effect of cleaning light debris and effectively avoids debris clogging the gate plate. The debris filtering and collection effect is better, ensuring the water flow effect, and the debris removal effect is better, effectively avoiding upstream debris from entering the downstream and causing pollution.
