Description

Technical Field

[0001] This application relates to the field of sluice gates, and in particular to a sluice gate drainage system. Background Technology

[0002] Currently, the sluice gate drainage system is set up between the upstream and downstream areas, and the sluice gates are opened for drainage and closed for water storage or flood control.

[0003] In related technologies, sluice gates are equipped with rubber seals on their gate plates, which abut against the walls or plates surrounding the gate plates for sealing. However, when the sluice gate is used for flood drainage, it needs to move upwards to allow water from upstream to flow downstream. During this movement, the sealing rubber is compressed and tightened, making it prone to wear when there is silt on the walls or plates. Therefore, after repeated opening and closing of the gate for flood drainage and water storage, the effectiveness of isolating the upstream and downstream areas can deteriorate. Summary of the Invention

[0004] In order to improve the problem that the isolation effect between upstream and downstream is easily reduced after multiple opening and closing of the gate for flood drainage and water storage, this application provides a sluice gate flood drainage system.

[0005] The sluice gate drainage system provided in this application adopts the following technical solution:

[0006] A sluice gate drainage system includes: a gate panel disposed between a breast wall and a gate pier; sealing structures are provided at both ends of the gate panel; a base plate disposed between an upstream connecting section and a downstream connecting section, and the base plate is located below the gate panel; a driving component for driving the gate panel to move up to the open position and down to the closed position; the sluice gate drainage system further includes: a transmission component for connecting the two sealing structures to the driving component; the driving component also causes the two sealing structures to be subjected to external forces that bring them closer together and external forces that move them away from each other through the transmission component; when the gate panel is in the closed position, the two sealing structures are subjected to external forces that move them away from each other; when the gate panel is between the open position and the closed position, the two sealing structures are subjected to external forces that bring them closer together.

[0007] By adopting the above technical solution, this application utilizes the fact that during flood drainage, as the gate panel moves upward to the open position, the sealing structures are subjected to external forces that bring them closer together. Therefore, the sealing structures will not press against other sealing walls or structures on the side of the gate panel with maximum force, making it easier for the gate panel to move upward and reducing resistance during this upward movement. This makes opening the gate easier for workers, whether manually or via external input. Furthermore, this application utilizes the fact that when the gate panel moves downward to the closed position, the two sealing structures are subjected to external forces that move them away from each other. This further strengthens the seal between the sealing structures and the sealing walls or structures on the side of the gate panel, even when they are already pressed against or tightly against the side of the gate panel, thus better ensuring the sealing function of the gate panel when not draining. Therefore, this application ensures that when the gate panel moves, the sealing structures press against the sealing walls with normal force or less than normal force. Furthermore, when the door panel is in the closed position, the drive and transmission components further increase the contact force between the sealing structure and the wall. Thus, even if the sealing structure wears out during normal use, the increased contact force can ensure the normal operation of the door panel and better guarantee that the door panel can support multiple drainage operations.

[0008] Preferably, the sluice gate drainage system further includes: a connector; the connector connects the drive component and the transmission component; the drive component drives the gate panel to move up and down via the connector; when the drive component drives the connector to move up, the transmission component causes the two sealing structures to be subjected to an external force that brings them closer together, and the gate panel moves up to the open position; when the drive component drives the connector to move down, the gate panel moves down to the closed position, and the transmission component causes the two sealing structures to be subjected to an external force that moves them away from each other.

[0009] By adopting the above technical solution and utilizing the connecting parts, the driving component can move the door panel up and down through the connecting parts, while simultaneously subjecting the two sealing structures to external forces that bring them closer together and external forces that move them further apart.

[0010] Preferably, the door panel is provided with a sliding groove and a mounting groove; the connector is provided in the mounting groove; a guide rod is provided in the sliding groove, the guide rod is slidably connected to the sliding groove, and the guide rod is fixed to the sealing structure; the transmission member forms a hinged connection between the guide rod and the connector, so that when the connector moves upward, the two sealing structures are subjected to an external force that brings them closer together, and when the connector moves downward, the two sealing structures are subjected to an external force that moves them away from each other.

[0011] By adopting the above technical solution, and utilizing the sliding groove and mounting groove, when the connecting piece moves upward, the hinge of the transmission component and the guide rod causes the two sealing structures to be subjected to external forces that bring them closer together. Conversely, when the connecting piece moves downward to the closed position, the hinge of the transmission component and the guide rod causes the two sealing structures to be subjected to external forces that move them away from each other. Therefore, without additional drive components in the door panel, the two sealing structures are subjected to both forces that bring them closer together and forces that move them away from each other, avoiding the problem of difficult repair due to damage to the drive device and the problem of poor heat dissipation in the drive device.

[0012] Preferably, the transmission component includes a connecting rope and a guide wheel; the guide wheel is disposed in the mounting groove; one end of the connecting rope is connected to the guide rod, and the other end passes through the guide wheel and is connected to the connecting member; an elastic element is disposed in the sliding groove, the elastic element being used to subject the two sealing structures to external forces that move them away from each other.

[0013] By adopting the above technical solution, and utilizing the connecting rope and guide wheel, when the connector moves upward, it first moves, and then the connector pulls the sealing structure through the connecting rope. After the two sealing structures are subjected to a certain external force that brings them closer together, the connector then drives the door panel to move upward. Conversely, when the connector moves downward to the lowest position, it continues to move downward, and the connecting rope no longer pulls the sealing structure. Thus, the two sealing structures are subjected to external forces that move them away from each other under the action of the elastic element. Therefore, by using the connecting rope and guide wheel, the internal structure of the door panel is simplified, and damage to the internal structure of the door panel requiring repair is better avoided when the two sealing structures are subjected to external forces that bring them closer together or move them away from each other.

[0014] Preferably, the connector has a counterweight structure; the connector is slidably connected to the mounting groove; a first abutting part is provided at the top of the mounting groove, and a second abutting part is provided at the top of the connector; the second abutting part is used to abut against the first abutting plate.

[0015] By adopting the above technical solution, when the driving component uses a rope to move the connecting component up and down, the counterweight structure can be used to press the connecting component against the door panel, giving the door panel sufficient weight for waterproofing. The first abutment part on the mounting groove and the second abutment part on the connecting component are for enabling the connecting component to move the door panel upward.

[0016] Preferably, the sealing structure includes: a pressure control mechanism and a rubber strip connected to the pressure control mechanism; the pressure control mechanism is connected to the side end of the door panel; the pressure control mechanism has multiple external force control points, and the pressure control mechanism applies external force to multiple points on the rubber strip through the multiple external force control points so that the rubber strip adheres to the wall or structure used for sealing.

[0017] By adopting the above technical solution, since in some cases the wall or structure used for sealing cannot perfectly match the side of the door panel, rubber strips are used to fill the gap between the side of the door panel and the wall or structure used for sealing. However, due to construction errors, temperature differences, or the age of the product, the degree of mismatch between the wall or structure used for sealing and the side of the door panel is significant. Normal rubber strips may not be able to completely fill the seal, while thicker rubber strips will result in greater friction between the side of the door panel and the wall or structure used for sealing, making installation difficult and hindering the upward and downward movement of the door panel. Therefore, this application utilizes a pressure control mechanism to apply external force to the rubber strips at different locations, allowing rubber strips of normal thickness to better adhere to the wall or structure used for sealing, thus better ensuring normal use and sealing effect.

[0018] Preferably, the sealing structure includes: a pressure control mechanism and a rubber strip connected to the pressure control mechanism; the pressure control mechanism is connected to the side end of the door panel; the pressure control mechanism has multiple external force control points, which apply external force to multiple points on the rubber strip to make the rubber strip conform to the wall or structure used for sealing. The rubber strip can deform, thereby filling any position of the wall or structure used for sealing.

[0019] Preferably, the pressure control mechanism includes: at least two mounting plates; the rubber strip is disposed on at least two of the mounting plates; and the number of the guide rod and the transmission component is the same as the number of the mounting plates.

[0020] Preferably, a groove is formed on the side end of the door panel, the mounting plate is located in the groove, and the mounting plate abuts against the inner wall of the groove; the direction of the protrusion is perpendicular to the side end of the door panel.

[0021] Preferably, the groove is provided with a plurality of protrusions, and the mounting plate is provided with a plurality of recesses, the protrusions being inserted into the recesses.

[0022] Preferably, a dredging structure is provided on the upstream side of the door panel; the dredging structure is used to clean the silt at the upstream connecting section.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. During drainage, as the gate panel moves upward to the open position, the sealing structure is subjected to external forces that bring it closer together. Therefore, the sealing structure will not press against other sealing walls or structures on the side of the gate panel with maximum force, making it easier for the gate panel to move upward and reducing resistance during this upward movement. This makes it easier for workers to open the gate, whether manually or through external input. Furthermore, the sealing structure is less likely to be damaged when it comes into contact with other sealing walls or structures.

[0025] 2. When the gate panel moves down to the closed position, the two sealing structures are subjected to external forces that move away from each other. As a result, the two sealing structures, which are already in contact with or tightly pressed against the side of the gate panel, further strengthen the sealing structure and the wall or structure used for sealing the side of the gate panel. This can better ensure the sealing function of the gate panel when drainage is not being carried out. Attached Figure Description

[0049] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0050] A sluice gate drainage system is provided, wherein the sluice gate drainage system is located between an upstream connecting section and a downstream connecting section.

[0051] Example 1:

[0052] See attached document Figure 1-38. The sluice gate drainage system includes: gate panel 1, base plate 2, drive component 3, and transmission component 4.

[0053] A gate panel 1 is positioned between the breast wall and the gate piers, with sealing structures 5 provided at both ends of the gate panel 1. The breast wall is located above the gate piers, and there are multiple gate piers. The gate panel 1 is located between any two gate piers and below the breast wall. Above the breast wall is the gate chamber, which houses components that control the opening and closing of the gate panel 1, such as the drive unit 3. The breast wall, gate piers, and gate chamber are all prior art and will not be described in detail.

[0054] A sealing wall and sealing structure 5 can be directly installed on the gate piers to achieve a seal between any two gate piers, separating the upstream and downstream connecting sections. Alternatively, a sealing structure can be installed on the gate piers to achieve a seal between the gate panel 1 and any two gate piers, separating the upstream and downstream connecting sections. The sealing structure can be a straight plate or a grooved plate.

[0055] The base plate 2 is positioned between the upstream connecting section and the downstream connecting section, and is located below the door plate 1. The door plate 1 abuts against the base plate, separating the upstream connecting section and the downstream connecting section. The driving component 3 is used to move the door plate 1 upward to the open position and downward to the closed position. The open position refers to the position where the door plate 1 is away from the base plate, and the closed position refers to the position where the door plate 1 abuts against the base plate.

[0056] The transmission component 4 is used to connect the two sealing structures 5 to the driving component 3. The driving component 3 also causes the two sealing structures 5 to be subjected to external forces that bring them closer together and external forces that move them away from each other through the transmission component 4.

[0057] When the gate panel 1 is in the closed position, the two sealing structures 5 are subjected to external forces that move away from each other. When the gate panel 1 moves down to the closed position, the two sealing structures 5 are subjected to external forces that move away from each other. Therefore, the two sealing structures 5, which are already in contact or tightly against the side of the gate panel 1, further strengthen the sealing structure 5 and the wall or structure used to seal the side of the gate panel 1. This can better ensure the sealing function of the gate panel 1 when drainage is not being carried out.

[0058] See attached document Figure 1-3 8-10, when the door panel 1 is between the open and closed positions, the two sealing structures 5 are subjected to external forces that bring them closer together; during the process of the door panel 1 moving upward to the open position, the sealing structures 5 are subjected to external forces that bring them closer together, so the sealing structures 5 will not press against other walls or structures used for sealing on the side of the door panel 1 with the tightest force, which will make it easier for the door panel 1 to move upward, and the resistance encountered during the upward movement will be reduced. When the staff opens the gate, it will be easier to open the gate, whether by manual opening or by external input drive.

[0059] Therefore, when the door panel 1 moves, this application ensures that the sealing structure 5 abuts against the wall with normal force or less than normal force. Furthermore, when the door panel 1 is in the closed position, the drive component 3 and transmission component 4 further increase the abutment force between the sealing structure 5 and the wall. This ensures that even if the sealing structure 5 wears down after use, the increased abutment force can further guarantee the normal operation of the door panel 1 and better ensure that the door panel 1 can support multiple drainage operations.

[0060] In some feasible solutions, the drive unit 3 directly employs two sets of drives. One set of drives is used to move the door panel 1 up and down, such as a hydraulic cylinder, winch, or threaded structure. The other set of drives is used to move the two sealing structures 5 closer together or further apart. The movement of the sealing structures 5 refers to the tendency of motion; the sealing structures 5 may not necessarily have obvious displacement, but this set of drives provides the corresponding tendency of motion for the sealing structures 5. This causes the sealing structures 5 to be subjected to external forces that bring them closer together or further apart, better pressing them against the wall or structure used for sealing. This set of drives can be such as a hydraulic cylinder, pneumatic cylinder, or electric cylinder. Multiple sets of drives can be set to make the force on the sealing structures 5 more even.

[0061] Example 2:

[0062] The difference between Example 2 and Example 1 is that the sluice gate drainage system further includes a connector 6. The connector 6 connects the drive component 3 and the transmission component 4. The drive component 3 drives the gate panel 1 to move upwards and downwards via the connector 6. When the drive component 3 drives the connector 6 upwards, the transmission component 4 causes the two sealing structures 5 to be subjected to an external force that brings them closer together, causing the gate panel 1 to move upwards to the open position. When the drive component 3 drives the connector 6 downwards, the gate panel 1 moves downwards to the closed position, and the transmission component 4 causes the two sealing structures 5 to be subjected to an external force that moves them away from each other.

[0063] See attached document Figure 8-10 The purpose of this embodiment is to combine the two sets of drives in Embodiment 1 into one set, and use the connector 6 to achieve that one set of drives can move the door panel 1 up and down, and can also apply external forces that move closer to each other and external forces that move further away from each other to the sealing structure 5. Since the sluice gate may not drain water for extended periods, this avoids the problems of excessive drives leading to maintenance difficulties or aging damage. It also avoids the difficulty in installing the drives.

[0064] See attached document Figure 1-3 8-10, Regarding a possible implementation scheme for connector 6 and door panel 1,

[0065] The door panel 1 is provided with a sliding groove 11 and a mounting groove 12 that are interconnected. Both the sliding groove 11 and the mounting groove 12 are located inside the door panel 1. The mounting groove 12 is located in the middle of the door panel 1 and extends through the top of the door panel 1. The sliding groove 11 is formed at the edge of the door panel 1 and extends through the side end of the door panel 1. The connecting member 6 is disposed in the mounting groove 12; a guide rod 7 is disposed in the sliding groove 11, the guide rod 7 is slidably connected to the sliding groove 11, and the guide rod 7 is fixed to the sealing structure 5. The transmission member 4 forms a hinged connection between the guide rod 7 and the connecting member 6, so that when the connecting member 6 moves upward, the two sealing structures 5 are subjected to an external force that brings them closer together, and when the connecting member 6 moves downward, the two sealing structures 5 are subjected to an external force that moves them further apart. The transmission member 4 is a hinge plate or rod, one end of the transmission member 4 is hinged to the connecting member 6, and the other end of the transmission member 4 is hinged to the guide rod 7. Since two sealing structures 5 are provided, there are also two guide rods 7 and two transmission components 4. Preferably, when the two sealing structures 5 are subjected to external forces that move away from each other, the two transmission components 4 are collinear with the two guide rods 7. Specifically, the sliding groove 11 and the mounting groove 12 have a clearance groove in the middle, which allows the transmission component 4 to move. Without additional drive components in the door panel 1, the two sealing structures 5 are subjected to external forces that move closer to each other and external forces that move away from each other, thus avoiding damage to the drive device that is difficult to repair and avoiding poor heat dissipation of the drive device.

[0066] The connector 6 adopts a block structure, and the inner wall of the mounting groove 12 has a protruding structure. When the connector 6 moves upward, it abuts against the protruding structure. If the connector 6 continues to move upward, it can drive the door panel 1 to move upward. When the connector 6 moves downward, it abuts against the bottom wall of the mounting groove 12. If the connector 6 continues to move downward, it can drive the door panel 1 to move downward. Alternatively, when the connector 6 moves downward, the door panel 1, under its own weight, moves downward until the protruding structure on the door panel 1 abuts against the connector 6. Thus, the upward and downward movement of the connector 6 can drive the upward and downward movement of the door panel 1.

[0067] Example 3:

[0068] The difference between Example 3 and Example 2 is that the transmission component 4 is replaced by a connecting rope 41 and a guide wheel 42 instead of a hinge plate or rod.

[0069] See attached document Figure 11The transmission component 4 includes a connecting rope 41 and a guide wheel 42. The guide wheel 42 is disposed in the mounting groove 12. One end of the connecting rope 41 is connected to the guide rod 7, and the other end passes through the guide wheel 42 and is connected to the connecting member 6. One end of the connecting rope 41 can be hinged or fixed to the guide rod 7, and the other end can be hinged or fixed to the connecting member 6. The upward movement of the connecting member 6 pulls the sealing structure 5 through the connecting rope 41, causing the sealing structures 5 to be subjected to a certain external force that brings them closer together. The precise movement process is as follows: first, the connecting member 6 moves; then, the connecting member 6 pulls the sealing structure 5 through the connecting rope 41, causing the two sealing structures 5 to be subjected to a certain external force that brings them closer together; after this, the connecting member 6 drives the door panel 1 to move upward. The cooperation between the connecting rope 41 and the guide wheel 42 is more reliable and less prone to problems compared to the hinged cooperation of a hinge plate or rod. An elastic element 43 is provided in the sliding groove 11. The elastic element 43 is used to subject the two sealing structures 5 to external forces that move them away from each other. The precise movement process is as follows: when the connecting piece 6 moves downward to the lowest position, the connecting piece 6 continues to move downward, and the connecting rope 41 no longer pulls on the sealing structure 5. Thus, under the action of the elastic element 43, the two sealing structures 5 are subject to external forces that move them away from each other. Therefore, by using the connecting rope 41 and the guide wheel 42, the internal structure of the door panel 1 is simplified, and the internal structure of the door panel 1 is better protected from damage requiring repair when the two sealing structures 5 are subjected to external forces that move them closer or further apart.

[0070] Example 4:

[0071] The difference between Example 4 and the above examples is that the way the driving component 3 moves the gate up and down is by using rope 82 to pull the gate up and by using the gate's own weight to move the gate down.

[0072] See attached document Figure 11 The connector 6 has a counterweight structure, meaning it has a significant weight. The connector 6 is slidably connected to the mounting groove 12; a first abutment portion 121 is provided at the top of the mounting groove 12, and a second abutment portion 61 is provided at the top of the connector 6. The second abutment portion 61 abuts against the first abutment plate. Both the first abutment portion 121 and the second abutment portion 61 are flat plates. When the driving member 3 uses the rope 82 to move the connector 6 up and down, the counterweight structure allows the connector 6 to press against the door panel 1, ensuring the door panel 1 has sufficient weight for waterproofing. The first abutment portion 121 on the mounting groove 12 and the second abutment portion 61 on the connector 6 are for enabling the connector 6 to move the door panel 1 upwards.

[0073] See attached document Figure 4-614. The sealing structure 5 in the above embodiments may include a retaining plate 51 and a sealing rubber 52. A retaining groove 53 is provided on the side end of the door panel 1, the retaining plate 51 is embedded in the retaining groove 53, and the sealing rubber 52 is fixed to the retaining plate 51. The retaining plate 51 is fixed to the guide rod 7. The retaining groove 53 communicates with the sliding groove 11. The sealing rubber 52 abuts against the wall or structure used for sealing.

[0074] See attached document Figure 4-6 Two sealing rubbers 52 are provided on a clamping plate 51, located on opposite sides of the clamping plate 51. One of the sealing rubbers 52 protrudes outward relative to the clamping plate 51, and a first through hole 521 is formed in the middle of the sealing rubber 52. A groove 522 is formed on the side of the sealing rubber 52, which is the surface formed by removing a portion of the sealing rubber 52. The hole surface of the first through hole 521 abuts against the wall or structure used for sealing, and the cut surface of the sealing rubber 52 also abuts against the wall or structure used for sealing, thereby achieving triple sealing. In addition, a fixing part 526 can be provided in the first through hole 521. The fixing part 526 is used to fix the sealing rubber 52 to the inside of the first through hole 521, thereby preventing the sealing rubber 52 from deforming too much outward at the position of the first through hole 521, which could easily lead to failure. The fixing part 526 can also abut against the wall or structure used for sealing, achieving multiple sealing. See the attached figure. Figure 14 Another sealing rubber 52 protrudes outward relative to the clamping plate 51. A second through hole 523 is formed in the middle of this sealing rubber 52, allowing for better deformation and abutment against the wall or structure used for sealing. A first support portion 524 and a second support portion 525 are fixedly disposed on the clamping plate 51, with the sealing rubber 52 positioned between them. The sealing rubber 52 has a connecting portion and a head portion. The connecting portion is located between the first support portion 524 and the second support portion 525, and the head portion is cylindrical and tangent to the connecting portion, allowing for better contact between the sealing rubber 52 and the wall used for sealing. Furthermore, the action of the first support portion 524 and the second support portion 525 prevents fatigue deformation of the entire head portion.

[0075] Example 5:

[0076] The difference between Example 5 and the above examples is that:

[0077] See attached document Figure 7 , 12The sealing structure 5 includes a pressure control mechanism and a rubber strip 54 connected to the pressure control mechanism. The pressure control mechanism is connected to the side end of the door panel 1. The pressure control mechanism has multiple external force control points, which apply external force to multiple points on the rubber strip 54 to make the rubber strip 54 conform to the wall or structure used for sealing. The rubber strip 54 can deform, thereby filling any position of the wall or structure used for sealing.

[0078] By adopting the above technical solution, since in some cases the wall or structure used for sealing cannot completely match the side of the door panel 1, a rubber strip 54 is used to fill the gap between the side of the door panel 1 and the wall or structure used for sealing. However, due to construction errors, temperature differences, or the age of the product, the degree of mismatch between the wall or structure used for sealing and the side of the door panel 1 is relatively large. A normal rubber strip 54 will not be able to completely fill the seal, while a thicker rubber strip 54 will result in greater friction between the side of the door panel 1 and the wall or structure used for sealing, which will not only make installation difficult but also hinder the upward and downward movement of the door panel 1. Therefore, this application utilizes a pressure control mechanism to apply external force to the rubber strip 54 at different positions, so that the rubber strip 54 of normal thickness can also better fit the wall or structure used for sealing, thus better ensuring normal use and sealing effect.

[0079] In one possible implementation of the pressure control mechanism, the pressure control mechanism includes: at least two mounting plates 55; a rubber strip 54 disposed on at least two of the mounting plates 55; and the number of guide rods 7 and transmission components 4 being the same as the number of mounting plates 55. A groove 56 is formed on the end side of the door panel 1, and the mounting plates 55 are embedded in the groove 56. The driving component 3 applies external force to the mounting plates 55 via the transmission components 4, and then the mounting plates 55 apply external force to the rubber strips 54, further pressing the rubber strips 54 against the wall or structure used for sealing. By utilizing the arrangement of at least two mounting plates 55 and the simultaneous application of external force by the guide rods 7 to at least two mounting plates 55, the rubber strips 54 on each mounting plate 55 can be deformed, resulting in a better match with the wall or structure used for sealing.

[0080] In some specific cases, the groove 56 is provided with multiple protrusions, and the mounting plate 55 is provided with multiple recesses, with the protrusions inserted into the recesses; the direction of the protrusions is perpendicular to the side end of the door panel 1. The protrusions and recesses guide the mounting plate 55.

[0081] See attached document Figure 13In another possible implementation of the pressure control mechanism, the pressure control mechanism includes a push plate 57 and a hydraulic bladder 58. The push plate 57 is fixed to the guide rod 7, the hydraulic bladder 58 is fixed to the push plate 57, and the rubber strip 54 is fixed to the hydraulic bladder 58. Utilizing the configuration of the hydraulic bladder 58, it can deform. Matching the shape of the hydraulic bladder 58 to the wall or structure used for sealing allows for better deformation of the rubber strip 54 to match the shape of the wall or structure used for sealing. The hydraulic bladder 58 can also be connected to an external hydraulic device to actively control its pressure.

[0082] In some other designs for connector 6, the mounting groove 12 is a through groove. The lower end of connector 6 is made of magnetic material. An electromagnet is installed below the base plate 2. When connector 6 moves down to the closed position, connector 6 and base plate 2 are attracted to each other, providing a greater downward force for connector 6, which helps ensure the stability of the closed position. A third abutment part 62 is provided at the lower end of connector 6, and a fourth abutment part 122 is provided in the mounting groove 12. After connector 6 moves down to the point where the third abutment part 62 abuts against the fourth abutment part 122, the continued downward movement of connector 6 will apply downward pressure to the door panel 1.

[0083] In other embodiments,

[0084] See attached document Figure 1 A dredging structure 8 is installed on one side of the gate panel 1 located at the upstream connecting section. The dredging structure 8 is used to clean the silt at the upstream connecting section. The dredging structure 8 includes: a net body 81, a first connecting component, and a second connecting component. The first connecting component connects one side of the net body 81 to the gate panel 1, and the second connecting component connects to the other side of the net body 81. A winch is installed in the gate chamber, and the second connecting component is connected to the winch via a rope 82. Multiple winches can be installed, some of which are used to control the opening of the gate panel 1, and others are used to connect to the rope 82. The first connecting component includes multiple connecting buckles, which are arranged obliquely on the gate panel 1. At least two winches are installed to connect to the second connecting component, and the rope 82 is connected to both ends of the second connecting component. The second connecting component uses connecting buckles, and at least two winches can control the length of the rope 82 to keep the second connecting component arranged obliquely. The second connecting component can be moved upwards using a winch, causing the net body 81 to tilt, allowing the sludge on the net body 81 to be discharged to the vicinity of the side end of the door panel 1. The sludge can then be collected at the side end of the door panel 1 using a collection tool, thus better protecting the downstream environment.

[0085] The dredging structure 8 may also include a suction pipe, a control valve, and a control pump. One end of the suction pipe is submerged below the water surface, while the other end outputs water. The control valve is located at the output end of the suction pipe. The control pump pumps the sludge and some water from the water surface outwards, thus achieving dredging. Preferably, the sludge and water are discharged into a collection tank. A wastewater purifier is installed in the collection tank to purify the water before it is discharged into the upstream connecting section. Preferably, the water is discharged near the rubber strip 54.

[0086] In some other embodiments, a net 81 can also be installed on the side of the gate panel 1 located in the downstream connecting section. One end of the net 81 is connected to the side of the gate panel 1 located in the downstream connecting section, and the other end is connected to the bottom of the downstream connecting section. When the gate panel 1 is opened, the net 81 will spread out under the gate panel 1 to intercept some of the silt, such as tree branches, thus better protecting the downstream environment.

[0087] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
