Technical Field
[0001] This invention relates to the field of flood control gate technology, specifically a flood control gate for water conservancy projects. Background Technology
[0002] Water conservancy projects are used to control and regulate surface water and groundwater in nature, so as to achieve the purpose of eliminating harm and promoting benefits. Water conservancy projects usually require the construction of different types of hydraulic structures such as dams and canals. Among them, flood control gates are basically an essential structure of every hydraulic structure. They mainly use their controllable opening and closing operation to control surface water, thereby achieving the purpose of flood control.
[0003] Existing sluice gates typically include arc-shaped, flat, and conical gates. Among them, flat gates have the simplest structure and are the most widely used. However, the opening and closing of existing flat gates mostly rely on a top-mounted motor and a suspension structure for raising and lowering. Since the gate is always closed for certain periods, excessive silt and impurities accumulate at the bottom of the gate over time. There is no corresponding structure to separate these accumulated impurities when the gate is opened, causing all of these impurities to be discharged downstream. At the same time, during the drainage process, large impurities from the upstream water are continuously discharged downstream, leading to severe accumulation at the downstream inlet, which may cause blockage and raise the water bed level, thus seriously affecting the downstream water storage and carrying capacity. Furthermore, floating garbage can only be retrieved manually, and there is no way to effectively separate floating garbage during the subsequent drainage process, greatly reducing the effectiveness of the sluice gate. Summary of the Invention

[0010] The filter structure includes a filter plate, on which filter ports are provided that extend through the upper and lower surfaces, and straight plates are movably installed inside the filter ports.
[0011] In a preferred embodiment, the limiting groove consists of two parts: a wide groove that extends vertically through its top for placing the upright plate, and an L-shaped narrow groove located at the wide groove for restricting the movement of the filter structure.
[0012] In a preferred embodiment, the scraping component is grid-shaped and has multiple inclined scraping strips that can be extended and retracted slightly. The bottom end of the scraping component is connected to the bottom end of the gate by two elastic ropes, and the scraping component is attached to one side of the gate. The scraping component can be rotated open around its top end.
[0013] In a preferred embodiment, both the traction motor and the traction wheel are mounted on the top of the outer frame via a support base, and one end of the traction rope is fixedly connected to the top of the gate.
[0014] In a preferred embodiment, both the outer frame and the gate are provided with positioning slots, and the shape of the positioning slots is adapted to the card strip. The upper and lower surfaces of the card strip are both embedded with movable balls.
[0015] In a preferred embodiment, the guide cavity is provided through an arc groove opened inside the housing, and the other end is connected to a discharge pipe through the bottom end of the housing. The guide plate is inclined downward and the end connected to the housing is located below the port of the guide cavity. The guide plate is a resettable elastic plate and is located on one side of the separation structure.
[0016] In a preferred embodiment, the strips are multiple strips evenly fitted onto two rollers, and a fixing strip connects each pair of adjacent strips; the maximum rotation radius of the separation box is smaller than the inner diameter of the shell.
[0017] In a preferred embodiment, the separation box includes a box body, the bottom of the box body is provided with a drainage groove, the top of the box body is an open structure and a horizontal plate is fixedly installed on one side of the top, and water outlets are evenly provided on one side of the box body, with vertical baffles movably installed inside the water outlets.

The straight strips are connected to the inside of the filter openings in a manner that allows them to rotate downwards only. The straight strips are all tilted when rotated and opened to the bottom of the filter plate. The length of the filter opening is greater than the distance between the two ends inside the tray that are in the same direction as the length of the filter opening.
[0020] The present invention has the following beneficial effects:
[0021] 1. The flood control gate of this water conservancy project has a tray and a filter structure installed on the water storage side of the gate. The filter structure is connected to the gate by a connecting rope. During the water storage process, impurities and particles at the bottom of the water will accumulate on the filter structure. When the gate moves downward to open, the filter structure will be moved by the connecting rope. The straight plates will droop under their own weight, opening the filter opening. The particles and impurities accumulated on the filter plate will fall from the filter opening into the tray. This prevents large particles and impurities from flowing downstream during the water drainage process when the gate is opened. Instead, they are collected in the collection box by the tray and treated, minimizing the rise of the riverbed downstream.
[0022] 2. The flood control gate of this water conservancy project, by setting the gate to open downwards, combines the functions of the separation structure and the filtration structure. This allows the water flow to be lifted upwards after impacting the filtration structure. The lifted water flow carries floating debris to the separation structure, where a continuously rotating separation box collects the debris, while the water is discharged through the belt and drainage channel. This not only achieves the function of drainage but also separates and cleans floating debris during the drainage process, improving the applicability of the flood control gate.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The flood control gates of water conservancy projects involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Please see Figure 1-5 A flood control gate for a water conservancy project includes an outer frame 1. Retaining walls 2 are fixedly installed at both ends of one side of the outer frame 1. Limiting grooves 3 are respectively opened on the opposite sides of the two retaining walls 2. A gate 4 is movably connected inside the outer frame 1. A traction structure 5 is installed on the top of the outer frame 1. Locking structures 6 are fixedly installed on the upper sides of both sides of the outer frame 1. A collection box 7 is fixedly installed on one side of the outer frame 1 at the bottom of the retaining wall 2. A scraping component 8 is movably installed on the side of the collection box 7 near the outer frame 1. The top of the retaining wall 2 is located at the traction structure. A top shell 9 is installed above the top shell 5. A separation structure 10 is movably installed between the top shell 9 and the retaining wall 2. A tray 11 is fixedly installed at the bottom between the two retaining walls 2. The collection box 7 and the tray 11 are connected by a conduit. A vertical plate 12 is movably installed in the limiting groove 3. A filter structure 13 is installed above the tray 11. A connecting rope 14 is fixedly connected to the upper surface of the filter structure 13 at the end of the vertical plate 12. The two sides of the collection box 7 are connected through to the ends of the collection box 7 in the above gate structure with the same configuration as the others.
[0035] Compared with existing technologies, this application provides a tray 11 and a filter structure 13 on the water storage side of the gate 4. The filter structure 13 is connected to the gate 4 via a connecting rope 14. During water storage, impurities at the bottom of the water accumulate on the filter structure 13. When the gate 4 moves downwards to open, the connecting rope 14 pulls the filter structure 13, causing the straight plate 133 to droop under its own weight, opening the filter opening 132. The accumulated impurities on the filter plate 131 then fall from the filter opening 132 into the tray 11. This prevents large impurities from flowing downstream during the drainage process of the gate 4, instead collecting them in the collection box 7 via the tray 11, minimizing the risk of riverbed rise downstream. Simultaneously, by adjusting the gate... 4 is configured to open downwards. This, combined with the functions of the separation structure 10 and the filter structure 13, allows the water flow to rise upwards after impacting the filter structure 13. The rising water flow carries floating debris to impact the separation structure 10. The continuously rotating separation box 103 inside the separation structure 10 can collect the debris, while the water is discharged through the belt 102 and the drainage channel 1032. This not only achieves the function of drainage, but also separates and cleans floating debris during the drainage process, improving the applicability of the flood control gate. Under the blocking effect of the vertical plate 12, it can be ensured that when the water level does not exceed the top of the vertical plate 12, the water fluctuations in the water storage project will not cause serious impact on the gate 4, greatly ensuring the service life of the gate 4.
[0036] Please see Figure 1-3 A flood control gate for a water conservancy project includes a limiting groove 3, which consists of two parts: a wide groove that is vertically opened through its top for placing a vertical plate 12, and an L-shaped narrow groove located at the wide groove for restricting the movement of a filter structure 13.
[0037] In this embodiment, it should be noted that by using the combination of the wide and narrow slots of the limiting slot 3, it is possible to facilitate the placement and removal of the upright plate 12 and ensure the stable limiting function of the upright plate 12. At the same time, it is also possible to enable the filter structure 13 to move according to the restriction of the narrow slot during the downward opening of the gate 4, thus ensuring the separation and filtration effect of the filter structure 13 on the bottom impurities during the drainage process.
[0038] Please see Figure 1-4 A flood control gate for a water conservancy project includes a scraping component 8, which is grid-shaped and has multiple inclined scraping strips that can be extended and retracted slightly. The bottom end of the scraping component 8 is connected to the bottom end of the gate 4 by two elastic ropes and the scraping component 8 is attached to one side of the gate 4. The scraping component 8 can be rotated around its top end to open.
[0039] In this embodiment, it should be noted that when the gate 4 moves to open, the scraping component 8 will automatically become a drooping state under its own weight. When the gate 4 moves down and passes the scraper on the scraping component 8, the mud adhering to it can be scraped off and guided into the collection box 7, where it is collected and processed together with the bottom impurities separated by the filter structure 13. When the gate 4 is closed, the scraping component 8 will be pulled up by the elastic rope to open one end of the collection box 7, which makes it easier to process the impurities collected in the collection box 7.
[0040] Please see Figure 2-4 A flood control gate for a water conservancy project includes a traction structure 5, which includes a traction motor 51. Traction wheels 52 are fixedly installed at both ends of the traction motor 51, and traction ropes 53 are wound and connected on the traction wheels 52.
[0041] In this embodiment, it should be noted that the traction motor 51 and the traction wheel 52 are both mounted on the top of the outer frame 1 through the support base. One end of the traction rope 53 is fixedly connected to the top of the gate 4. In this way, the gate 4 can be moved upward by starting the traction motor 51, and the gate 4 can also be moved downward by starting the traction motor 51 to provide a certain traction force, so as to avoid impact damage to the gate 4 during the downward movement.
[0042] Please see Figure 2-6 A flood control gate for a water conservancy project includes a locking structure 6, which includes a base 61. The base 61 is fixedly installed at one end of the outer frame 1, and an electric push rod 62 is fixedly installed on the base 61. A locking strip 63 is fixedly installed at one end of the telescopic extension of the electric push rod 62.
[0043] In this embodiment, it should be noted that both the outer frame 1 and the gate 4 are provided with positioning slots, and the shape of the positioning slots is adapted to the card strip 63. The upper and lower surfaces of the card strip 63 are embedded with movable ball bearings. In this way, when the electric push rod 62 is activated to push the card strip 63 into the positioning slot or pull it out from it, the card strip 63 can be smoothly moved in and out, thereby ensuring the response speed and effect of the gate 4 opening and closing.
[0044] Please see Figure 5-9 A flood control gate for a water conservancy project includes a top shell 9, which includes a housing 91. A guide cavity 92 is provided inside one side of the housing 91, and an arc groove is provided at the bottom of the housing 91. A guide plate 93 is fixedly installed on the side of the arc groove located in the guide cavity 92.
[0045] In this embodiment, it should be noted that the conveying cavity 92 is provided through the arc groove opened in the housing 91, and the other end is connected to the bottom end of the housing 91 and a discharge pipe. The guide plate 93 is inclined downward and the end connected to the housing 91 is located below the port of the conveying cavity 92. The guide plate 93 is a resettable elastic plate. The guide plate 93 is located on one side of the separation structure 10 and covers it. In this way, when the floating garbage collected on the separation structure 10 rotates to the top of the guide plate 93, the garbage will be poured out from the separation box 103 onto the guide plate 93, and then slide down along the upper surface of the guide plate 93 into the conveying cavity 92, and finally be discharged and collected from the discharge pipe. The rotation of the separation structure 10 will cause the guide plate 93 to bend, and after the separation structure 10 leaves the contact with the guide plate 93, it will automatically spring back and be ready to receive the next garbage poured from the separation box 103, ensuring the continuity of the use of the entire structure.
[0046] Please see Figure 3 and Figure 5 A flood control gate for a water conservancy project includes a separation structure 10, which includes two rollers 101. A strip 102 is movably sleeved on the two rollers 101, and a separation box 103 is uniformly fixed on the outer surface of the strip 102.
[0047] In this embodiment, it should be noted that multiple strips 102 are evenly sleeved on two rollers 101, and a fixed strip connects each pair of adjacent strips 102. The maximum rotation radius of the separation box 103 is smaller than the inner diameter of the housing 91. Thus, when the water flow impacts the filter structure 13 and is lifted up, the water will carry the garbage to impact the separation box 103. The garbage will be separated by the separation box 103, and the water will be discharged through the gap between the strips 102 and the bottom of the separation box 103. The garbage will be poured onto the guide plate 93 after the separation box 103 rotates to the top. This allows for the simultaneous and continuous separation of garbage during the discharge process, greatly improving the effectiveness of the gate.
[0048] Please see Figure 5 and Figure 8 A flood control gate for a water conservancy project includes a separation box 103, which includes a box body 1031. A drainage channel 1032 is provided at the bottom of the box body 1031. The top of the box body 1031 is an open structure and a horizontal plate 1033 is fixedly installed on one side of the top. A water outlet 1034 is evenly provided on one side of the box body 1031, and a vertical baffle 1035 is movably installed inside the water outlet 1034.
[0049] In this embodiment, it should be noted that the width of the horizontal plate 1033 is less than or equal to half the width of the inner surface of the box 1031. The vertical baffle 1035 is rotatably connected to the box 1031. A coil spring is installed on the connecting shaft of the vertical baffle 1035, and the top of the vertical baffle 1035 is at the same height as the top of the horizontal plate 1033. The vertical baffle 1035 is in the open state under no external force. In this way, after the water carrying the garbage is flushed into the box 1031, the water can open the vertical baffle 1035 from the inside of the box 1031 under the impact and then be discharged. The floating garbage will be left inside the box 1031. The unidirectional rotating water outlet 1034 can ensure that the external water will not be flushed into the box 1031 from the water outlet 1034, thereby minimizing the impact of water flow from the water outlet 1034 and causing the garbage collected in the box 1031 to be flushed out.
[0050] Please see Figure 3 and Figure 7 A flood control gate for a water conservancy project includes a filter structure 13, the filter structure 13 includes a filter plate 131, the filter plate 131 has a filter port 132 that penetrates the upper and lower surfaces, and a straight bar plate 133 is movably installed inside the filter port 132.
[0051] In this embodiment, it should be noted that the filter openings 132 are non-uniformly spaced, with the distance between them gradually decreasing towards the end of the filter plate 131 connected to the connecting rope 14. The width of the filter openings 132 towards the end of the connecting rope 14 also gradually decreases. The straight bar 133 is connected to the inside of the filter openings 132 in a manner that allows it to rotate downwards only. Furthermore, the straight bar 133 is tilted when it rotates open to below the filter plate 131. The length of the filter openings 132 is greater than the distance between the two ends of the tray 11 that are in the same length direction as the filter openings 132. Thus, when the entire filter structure 13 is lifted by the connecting rope 14, the straight bar 133 will rotate downwards under its own weight, thereby opening the filter openings 132. Due to the non-uniform size of the filter openings 132, this allows for greater... Impurities at the bottom of the water are separated and filtered out from the bottom of the filter plate 131. Smaller impurities are more affected by the water flow, so they are separated and filtered out from the filter port 132 at the upper end of the filter plate 131. The inclined filter plate 131 not only generates a lifting force when the water is impacted, but also effectively blocks the garbage at the bottom of the water, greatly improving the cleanliness of the water when draining from the gate. After the gate 4 moves down, the scraping component 8 will fit against one end of the collection box 7, so that the inside of the collection box 7 is sealed, and the impurities washed down from the tray 11 by the water flow can be collected in the collection box 7 and discharged. After the gate 4 is closed, the scraping component 8 will be opened, which also facilitates the cleaning of the inside of the collection box 7.
[0052] It should be noted that the drive source and triggering method required for the traction motor 51, electric push rod 62 and separation structure 10 in this application all adopt existing technology, and will not be described in detail in this application.
[0053] Working principle: When water storage is required, the gate 4 is in the state of closing the outer frame 1 port. At the same time, the vertical plate 12 acts as a water-blocking structure at the front end of the gate 4 to prevent the water flow from directly impacting the gate 4. At this time, the filter structure 13 is in a horizontal state and closes the upper surface of the vertical plate 12.
[0054] When drainage is needed, the electric push rod 62 is activated. The electric push rod 62 retracts, pulling the retaining strip 63 out from both sides of the gate 4. At the same time, the traction motor 51 is activated, which slowly pulls the gate 4 down to open the water flow channel. During the descent of the gate 4, the filter structure 13 is lifted by the connecting rope 14. The filter structure 13 moves to an inclined state in the narrow groove of the limiting groove 3. The straight plate 133 rotates downward under its own weight, opening the filter port 132 so that large debris at the bottom can pass through the filter port 132 into the tray 11 and then be discharged into the collection box 7. During the descent of the gate 4, the scraping component 8 is driven to fit tightly against one side of the collection box 7. At the same time, the external drive source drives the roller 101 to rotate, which in turn drives the separation box 103 to rotate through the belt 102. When the water flows and impacts the surface of the filter structure 13, it will be lifted up and then impact the separation box 103. The water carrying the floating garbage enters the box 1031, where the garbage remains. The water is opened by the drainage channel 1032 and the impact on the vertical baffle 1035 and flows out from the outlet 1034. When the box 1031 carrying the garbage rotates to the top of the roller 101, the continued rotation will cause the opening of the box 1031 to face downwards, and the garbage will fall onto the guide plate 93. Then, it will slide down the upper surface of the guide plate 93 into the conveying chamber 92 and finally be discharged from the conveying chamber 92 for centralized collection. The continued rotation of the box 1031 will press down on the guide plate 93 and bend it. When the box 1031 leaves, the guide plate 93 will spring back to its original position to continue the next garbage collection.
[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
