Description

Technical Field

[0001] This invention relates to the technical field of hard-seal gates, and in particular to a hard-seal gate. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. The main function of water conservancy projects is to control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. In the process of implementation, hard-sealed gates are often installed between the upstream and downstream of the river to block the water from the upstream.

[0003] Typical hard-seal gates, such as the water diversion method and device for water conservancy construction disclosed in patent CN112942261B and the water conservancy river channel gate disclosed in patent CN212405038U, achieve the obstruction and discharge of river water by raising and lowering the gate.

[0004] However, during use, it was found that the existing hard-seal gate structure is relatively simple, with all gates being solid structures and heavy, making installation difficult. Furthermore, when the gate is raised to release water, debris from the riverbed easily falls into the grooves of the base, affecting the sealing effect after the gate is closed. In winter, when the river freezes, the ice layer can easily compress the gate, causing it to deform, which also affects the sealing effect. In addition, it is inconvenient to raise the gate after it freezes, resulting in poor practicality. Therefore, there is an urgent need for a hard-seal gate to improve the above problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a hard-seal gate that repeatedly raises and lowers the water-blocking mechanism to draw in river water and discharge some of it into a limiting mechanism, which then compresses the water-blocking mechanism. The water-blocking mechanism is installed in a support mechanism. Then, by raising the water-blocking mechanism, river water flows through the support mechanism while multiple drainage mechanisms draw in river water again. Afterward, by lowering the water-blocking mechanism, multiple drainage mechanisms are compressed, causing them to discharge river water into the limiting mechanism and a cleaning mechanism. The limiting mechanism discharges excess river water, and the cleaning mechanism sprays water to clean the bottom of the support mechanism. When the filter mechanism is clogged, the cleaning mechanism sprays hot water to clean the aquatic plants on the filter mechanism, thereby improving the practicality of the equipment.

[0006] A hard-seal gate of the present invention includes a support mechanism; it also includes a water-blocking mechanism, a limiting mechanism, a filtering mechanism, a cleaning mechanism and multiple drainage mechanisms. The water-blocking mechanism is installed on the support mechanism, the limiting mechanism is installed in the water-blocking mechanism, and the filtering mechanism, the cleaning mechanism and multiple drainage mechanisms are all installed on the water-blocking mechanism. The supporting mechanism supports the water-blocking mechanism, the limiting mechanism limits the water-blocking mechanism, the water-blocking mechanism blocks the river water, the filtering mechanism intercepts impurities in the river water, the cleaning mechanism cleans the bottom of the supporting mechanism and the filtering mechanism, and the drainage mechanism provides river water to the limiting mechanism and the cleaning mechanism. By repeatedly raising and lowering the water-blocking mechanism, the drainage mechanism draws in river water and discharges some of it into the limiting mechanism. The limiting mechanism then compresses the water-blocking mechanism, which is then installed in the support mechanism. Afterward, by raising the water-blocking mechanism, river water flows through the support mechanism, while multiple drainage mechanisms draw in river water again. Then, by lowering the water-blocking mechanism, the multiple drainage mechanisms are compressed, causing them to discharge river water into the limiting mechanism and the cleaning mechanism. The limiting mechanism discharges excess river water, and the cleaning mechanism sprays out river water to clean the bottom of the support mechanism. When the filter mechanism becomes clogged, the cleaning mechanism sprays hot water to clean the aquatic plants on the filter mechanism, thus improving the equipment's practicality.

[0007] Preferably, the support mechanism includes a base, two sets of support columns, and a crossbeam. The bottom ends of the two sets of support columns are connected to the top ends of the base, and the top ends of the two sets of support columns are connected to the bottom ends of the crossbeam. The top of the base is provided with two sets of grooves, and the two sets of support columns are provided with multiple sets of limiting grooves. The water-blocking mechanism is supported by the two sets of support columns and the crossbeam. The water-blocking mechanism is blocked by the base and the two sets of support columns, thereby improving the practicality of the equipment.

[0008] Preferably, the water-blocking mechanism includes a top plate, two sets of guide grooves, multiple sets of sliders, two sets of gate plates, a thermal insulation telescopic sleeve, a screw, a driver, a telescopic guard plate, multiple sets of third support springs, two sets of first limiting frames and second limiting frames. The driver is installed on the top of the crossbeam. The top end of the screw passes through the crossbeam and the driver, and the surface of the screw is threaded to the middle of the crossbeam. The bottom end of the screw is rotatably installed on the top of the top plate. Both sets of guide grooves are installed on the bottom of the top plate. Multiple sets of sliders are slidably installed in the two sets of guide grooves. The top ends of the two sets of gate plates are respectively installed on the bottom ends of the multiple sets of sliders. The thermal insulation telescopic sleeve and multiple sets of third support springs are installed between the two sets of gate plates. Both sets of first limiting frames are installed on one set of gate plates and on the other set of gate plates, and the second limiting frame is located in the middle of the two sets of first limiting frames. A sealing block is provided at the bottom end of each set of gate plates. The telescopic guard plate is installed on the thermal insulation telescopic sleeve. At the bottom, multiple sets of first support springs are installed on the telescopic guard plate, and guide rails are installed on the left and right sides of both sets of gate plates. The two sets of gate plates and the thermal insulation telescopic sleeve are placed between the two sets of support columns. The two sets of gate plates are supported by multiple sets of third support springs, and the second limit frame slides between the two sets of first limit frames to limit the two sets of gate plates. The screw is installed in the middle of the driver, and the driver drives the screw to rotate, adjusting the height of the two sets of gate plates and the thermal insulation telescopic sleeve. Then, the drainage mechanism drains water into the limit mechanism, causing the limit mechanism to expand. The multiple sets of guide rails on the two sets of gate plates are respectively inserted into the multiple sets of limit grooves on the two sets of support columns. Then, the driver drives the screw to rotate again, causing the sealing block on the gate plate to extend into the groove at the top of the base. The two sets of gate plates, together with the two sets of support columns and the base, block the river water, thereby improving the practicality of the equipment.

[0009] Preferably, the limiting mechanism includes a water bladder, a first water supply pipe, multiple sets of second support springs, and multiple sets of casters. The water bladder is mounted on two sets of gate plates, and a solenoid valve is installed at the bottom of the water bladder. A return spring is installed inside the water bladder. The first water supply pipe is mounted on one set of gate plates, with one end communicating with the interior of the water bladder and the other end communicating with part of the drainage mechanism. Multiple sets of second support springs are respectively mounted on the left and right ends of the two sets of gate plates, and multiple sets of casters are respectively mounted on multiple sets of second support springs. The two sets of gate plates are installed in place by the elasticity of multiple sets of third support springs. The water-blocking mechanism repeatedly rises and falls, causing multiple drainage mechanisms to draw river water into its interior. Then, some drainage mechanisms discharge the river water into the first water supply pipe, and then the first water supply pipe discharges the river water into the water bladder, causing the water bladder to expand and squeeze the two sets of gate plates. At the same time, multiple sets of casters roll on the inner walls of the two sets of support columns to support the two sets of gate plates, thereby improving the ease of installation of the water-blocking mechanism.

[0010] Preferably, the filtration mechanism includes two sets of drive mechanisms, two sets of frames, two sets of filter plates, and multiple sets of baffles. The two sets of frames are respectively installed on the top of the two sets of gate plates, the two sets of filter plates are respectively installed in the middle of the two sets of frames, the two sets of drive mechanisms are respectively installed on the two sets of frames, and the multiple sets of baffles are respectively installed on the two sets of drive mechanisms. The drive mechanisms push the multiple sets of baffles forward, creating gaps between the multiple sets of baffles and the frames. River water crashes onto the multiple sets of baffles and then flows between the frames and the baffles. After that, the river water flows through the filter plates, which filter the river water and block impurities in the river water, thereby improving the practicality of the equipment.

[0011] Preferably, the drive mechanism includes multiple sets of cylinders, all of which are mounted on the frame, and the multiple sets of baffles are respectively mounted on the multiple sets of cylinders; by extending the multiple sets of cylinders, the multiple sets of baffles are unfolded in a stepped manner, so that suitable gaps are formed between the multiple sets of baffles to facilitate the passage of river water and to block larger debris, thereby reducing the damage of larger debris to the filter plates and improving the practicality of the equipment.

[0012] Preferably, the cleaning mechanism includes multiple sets of nozzles, a second water supply pipe, and two sets of baffles. The multiple sets of nozzles are respectively installed at the bottom ends of the two sets of second water supply pipes and at the rear ends of the multiple sets of baffles. The second water supply pipes are installed on another set of gate plates. The two sets of baffles are respectively installed on the two sets of gate plates to block the first water supply pipe, the second water supply pipe, and the water bladder. One end of the second water supply pipe is connected to the interior of the remaining multiple sets of drainage mechanisms, and the other end of the second water supply pipe is connected to the multiple sets of nozzles. When the water blocking mechanism rises, the multiple sets of drainage mechanisms extend to draw in river water. Then, when the water blocking mechanism descends, the multiple sets of drainage mechanisms are squeezed, and some of the drainage mechanisms discharge the river water into the second water supply pipe. The river water is heated through the second water supply pipe, causing the multiple sets of nozzles to spray the river water out, cleaning the impurities in the groove at the top of the base and the aquatic plants on the filter plate, thereby improving the practicality of the equipment.

[0013] Preferably, the drainage mechanism includes a fixed base, a telescopic water bladder, and two sets of one-way valves. The fixed base is installed on the gate plate, the telescopic water bladder is installed on the fixed base, and the two sets of one-way valves are respectively installed at the top and bottom of the telescopic water bladder. When the water blocking mechanism is raised, the telescopic water bladder unfolds, and river water flows into the interior of the telescopic water bladder through the bottom one-way valve. Then, the water blocking mechanism reduces pressure, and the telescopic water bladder is squeezed by the fixed base and the support column, causing the telescopic water bladder to contract. The one-way valve at the top of the telescopic water bladder opens, draining the river water, thereby improving the practicality of the equipment.

[0014] Preferably, both sets of gate plates are provided with reinforcing ribs, and the first water supply pipe and the second water supply pipe are respectively installed on the reinforcing ribs of the two sets of gate plates. The reinforcing ribs on the two sets of gate plates conduct part of the heat diffused on the first water supply pipe and the second water supply pipe, which reduces the temperature inside the insulation expansion sleeve in summer, and in winter, the temperature diffused by the reinforcing ribs causes the ice layer around the two sets of gate plates to heat up and melt, reducing the pressure of the ice layer on the two sets of gate plates, thereby improving the practicality of the equipment.

[0015] The installation and cleaning method for hard-seal gates includes the following steps: S1. Place two sets of gate plates and thermal insulation expansion sleeves between two sets of support columns. Support the two sets of gate plates with multiple sets of third support springs, and slide the second limit frame between the two sets of first limit frames to limit the two sets of gate plates. Install the screw in the middle of the driver and drive the screw to rotate to adjust the height of the two sets of gate plates and thermal insulation expansion sleeves. Then drain water into the limit mechanism through the drainage mechanism to expand the limit mechanism. Insert multiple sets of guide rails on the two sets of gate plates into multiple sets of limit grooves on the two sets of support columns. Then drive the screw to rotate again through the driver to insert the sealing block on the gate plate into the groove at the top of the base. The two sets of gate plates, together with the two sets of support columns and the base, block the river water. S2. When the water level is high, multiple sets of cylinders extend to unfold multiple sets of baffles in a stepped manner, creating suitable gaps between the baffles so that the river water can pass through the gaps between the baffles and block larger debris. Then, the debris in the river water is filtered again through the filter plate. S3. When discharging water, the drive reverses the direction of the pump, causing the screw to rotate and raising the water-blocking mechanism. This allows the river water to flow through the support mechanism, and multiple drainage mechanisms extend to draw in the river water. When the water-blocking mechanism descends, the multiple drainage mechanisms are squeezed, and some of them discharge the river water into the second water supply pipe. The second water supply pipe heats the river water, causing multiple nozzles to spray it out to clean impurities in the groove at the top of the base and aquatic plants on the filter plate. S4. In winter, the interior of the insulation expansion sleeve is heated through the first and second water supply pipes to prevent the water in the water bladder from freezing. The heat diffused from the first and second water supply pipes is discharged through the reinforcing ribs on the two sets of gate plates, so that the ice around the two sets of gate plates is heated and melted, reducing the pressure of the ice on the two sets of gate plates. S5. When a set of gate plates is frozen, some river water in the water bladder is released through the solenoid valve on the water bladder, causing the insulation expansion sleeve to contract, which facilitates the separation of the gate plate from the ice layer.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the gate is raised, the drainage mechanism collects river water. When the gate is lowered, the drainage mechanism is squeezed to allow the river water to enter the second water supply pipe. The water is heated through the second water supply pipe, and multiple sets of nozzles spray water to clean the grooves of the base and the filter plate. 2. By adjusting the water volume in the water bladder, it is convenient to install the two sets of gate plates onto the two sets of support columns, or to drain the river water in the water bladder to shrink the insulation expansion sleeve, making it convenient to separate the two sets of gate plates from the two sets of support columns, thus improving the ease of equipment installation and disassembly. 3. In winter, the continuous heating through the first and second water supply pipes melts the ice around the equipment, reducing the pressure of the ice on the gate plate. Attached Figure Description

Multiple sets of second support springs 19 are respectively installed on the left and right ends of the two sets of gate plates 9, and multiple sets of casters 20 are respectively installed on multiple sets of second support springs 19. The filtration mechanism includes two sets of drive mechanisms, two sets of frames 21, two sets of filter plates 22, and multiple sets of baffles 23. The two sets of frames 21 are respectively installed on the top of the two sets of gate plates 9, the two sets of filter plates 22 are respectively installed in the middle of the two sets of frames 21, the two sets of drive mechanisms are respectively installed on the two sets of frames 21, and the multiple sets of baffles 23 are respectively installed on the two sets of drive mechanisms. The drive mechanism includes multiple sets of cylinders 24, all of which are mounted on the frame 21, and the multiple sets of baffles 23 are respectively mounted on the multiple sets of cylinders 24. The cleaning mechanism includes multiple sets of nozzles 25, a second water supply pipe 26, and two sets of baffles 27. The multiple sets of nozzles 25 are respectively installed at the bottom end of the two sets of second water supply pipes 26 and at the rear end of the multiple sets of baffles 23. The second water supply pipes 26 are installed on another set of gate plates 9. The two sets of baffles 27 are respectively installed on the two sets of gate plates 9 to block the first water supply pipe 18, the second water supply pipe 26, and the water bag 17. One end of the second water supply pipe 26 is connected to the interior of the remaining multiple sets of drainage mechanisms, and the other end of the second water supply pipe 26 is connected to the multiple sets of nozzles 25. The drainage mechanism includes a fixed base 28, a telescopic water bladder 29, and two sets of one-way valves 30. The fixed base 28 is installed on the gate plate 9, the telescopic water bladder 29 is installed on the fixed base 28, and the two sets of one-way valves 30 are respectively installed at the top and bottom of the telescopic water bladder 29. Both sets of gate plates 9 are provided with reinforcing ribs 31, and the first water supply pipe 18 and the second water supply pipe 26 are respectively installed on the reinforcing ribs 31 of the two sets of gate plates 9. First, place the two sets of gate plates 9 and the thermal insulation expansion sleeve 10 between the two sets of support columns 2. Install the screw 11 in the middle of the driver 12. At the same time, support the two sets of gate plates 9 through multiple sets of third support springs 32. Drive the screw 11 to rotate through the driver 12 to adjust the height of the two sets of gate plates 9 and the thermal insulation expansion sleeve 10. Then, drain water into the limiting mechanism through the drainage mechanism to expand the limiting mechanism. This allows the multiple sets of guide rails 15 on the two sets of gate plates 9 to extend into the multiple sets of limiting grooves 5 on the two sets of support columns 2. The actuator 12 drives the screw 11 to rotate again, causing the sealing block 16 on the gate plate 9 to extend into the groove 4 at the top of the base 1. The two sets of gate plates 9, in conjunction with the two sets of support columns 2 and the base 1, block the river water. When the water level is high, multiple sets of cylinders 24 extend, unfolding multiple sets of baffle plates 23 in a stepped manner, creating suitable gaps between the baffle plates 23. This allows the river water to pass through these gaps, while also blocking larger debris. Finally, the water is filtered again by the filter plate 22. During filtration and water discharge, the drive 12 reverses its direction, rotating the screw 11 to raise the water-blocking mechanism, allowing the river water to flow over the support mechanism. Multiple drainage mechanisms extend, drawing in the river water. When the water-blocking mechanism descends, the drainage mechanisms are compressed, and some discharge the river water into the second water supply pipe 26. The second water supply pipe 26 heats the river water, causing multiple nozzles 25 to spray it out, cleaning impurities in the groove 4 at the top of the base 1 and removing aquatic plants from the filter plate 22. In winter, the water is discharged through the first water supply pipe 18... The second water supply pipe 26 heats the inside of the insulation expansion sleeve 10 to prevent the water in the water bladder 17 from freezing. The heat diffused from the first water supply pipe 18 and the second water supply pipe 26 is discharged through the reinforcing ribs 31 on the two sets of gate plates 9, so that the ice around the two sets of gate plates 9 is heated and melted, reducing the pressure of the ice on the two sets of gate plates 9. When one set of gate plates 9 is frozen, some river water in the water bladder 17 is released through the solenoid valve on the water bladder 17, so that the insulation expansion sleeve 10 can be contracted, making it easy for the gate plate 9 to separate from the ice.

[0021] The main functions achieved by this invention are: to improve the water-blocking effect of the equipment, to improve the ease of equipment installation, and to improve the service life of the equipment; 1. Improve the water blocking effect of the equipment: When the gate is lowered, the drainage mechanism is squeezed to allow river water to enter the second water supply pipe 26. The water is heated through the second water supply pipe 26, and multiple sets of nozzles 25 spray water out to clean the groove 4 of the base 1 and the filter plate 22, so as to facilitate the equipment to filter the river water and reduce impurities between the base 1 and the gate plate 9, so that the base 1 and the gate plate 9 fit tightly. 2. Improve the ease of equipment installation: By adjusting the water volume in the water bladder 17, it is easy to install the two sets of gate plates 9 onto the two sets of support columns 2, thus improving the ease of equipment installation. 3. Improve equipment lifespan: In winter, the continuous heating of the first water supply pipe 18 and the second water supply pipe 26 melts the ice around the equipment, reducing the pressure of the ice on the gate plate 9.

[0022] In winter, the interior of the heat-insulating telescopic sleeve 10 is heated through the first water supply pipe 18 and the second water supply pipe 26 to prevent the water in the water bladder 17 from freezing.

7. The method for installing and cleaning a hard-seal gate according to any one of claims 1 to 6 includes the following steps: S1. Place the two sets of gate plates (9) and the thermal insulation expansion sleeve (10) between the two sets of support columns (2), support the two sets of gate plates (9) with multiple sets of third support springs (32), and make the second limit frame (34) slide between the two sets of first limit frames (33) to limit the two sets of gate plates (9). Install the screw (11) in the middle of the driver (12), and drive the screw (11) to rotate through the driver (12) to limit the height of the two sets of gate plates (9) and the thermal insulation expansion sleeve (10). The degree is adjusted, and then the drainage mechanism drains water into the limiting mechanism, causing the limiting mechanism to expand. The multiple guide rails (15) on the two sets of gate plates (9) are respectively inserted into the multiple limiting grooves (5) on the two sets of support columns (2). Then the screw (11) is driven to rotate again by the driver (12), so that the sealing block (16) on the gate plate (9) is inserted into the groove (4) at the top of the base (1). The two sets of gate plates (9) cooperate with the two sets of support columns (2) and the base (1) to block the river water. S2. When the water level is high, multiple sets of cylinders (24) extend to unfold multiple sets of baffles (23) in a stepped manner, so that a suitable gap is formed between the multiple sets of baffles (23), allowing the river water to pass through the gap between the multiple sets of baffles (23) and blocking larger debris. Then, the debris in the river water is filtered again through the filter plate (22). S3. When releasing water, the drive (12) reverses to drive the screw (11) to rotate, raising the water blocking mechanism so that the river water flows through the support mechanism. Multiple drainage mechanisms extend to suck in the river water. When the water blocking mechanism descends, multiple drainage mechanisms are squeezed, and some drainage mechanisms discharge the river water into the second water supply pipe (26). The river water is heated through the second water supply pipe (26), causing multiple nozzles (25) to spray the river water to clean the impurities in the groove (4) at the top of the base (1) and the aquatic plants on the filter plate (22). S4. In winter, the interior of the heat-insulating expansion sleeve (10) is heated through the first water supply pipe (18) and the second water supply pipe (26) to prevent the water in the water bag (17) from freezing. The heat diffused on the first water supply pipe (18) and the second water supply pipe (26) is discharged through the reinforcing ribs (31) on the two sets of gate plates (9), so that the ice around the two sets of gate plates (9) heats up and melts, reducing the pressure of the ice on the two sets of gate plates (9). S5. When a set of gate plates (9) are frozen, some of the river water in the water bladder (17) is released through the solenoid valve on the water bladder (17), so that the heat insulation expansion sleeve (10) contracts, making it easier for the gate plate (9) to separate from the ice layer.
