Description

Technical Field

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

[0002] Currently, the sluice drainage system is set up between the upstream and downstream, and uses the opening of the sluice to drain water and the closing of the sluice to store water or prevent floods.

[0003] In related art, a rubber seal is installed on the gate plate of a sluice gate. The rubber seal abuts against the wall or plate at the edge of the gate plate to form a seal. However, when the sluice gate is used to drain water, it needs to move upward to allow upstream water to flow downstream. During this movement, the sealing rubber is compressed and pressed against the wall or plate, which can easily wear out when silt accumulates on the wall or plate. This can lead to a decrease in the isolation between upstream and downstream after repeated opening and closing of the gate to drain water and then closing the gate to store water. Summary of the Invention

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

[0005] The present application provides a sluice drainage system that adopts the following technical solutions: A sluice drainage system comprises: a door panel, arranged between a breast wall and a pier; sealing structures are arranged on both side ends of the door panel; a bottom plate, arranged between an upstream connecting section and a downstream connecting section, and the bottom plate is located below the door panel; a driving member, used to drive the door panel to move up to an open position and down to a closed position; the sluice drainage system further comprises: a transmission member, the transmission member is used to connect the two sealing structures with the driving member; the driving member also causes the two sealing structures to be subjected to external forces approaching each other and external forces moving away from each other through the transmission member; when the door panel is located in the closed position, the two sealing structures are subjected to external forces moving away from each other; when the door panel is located between the open position and the closed position, the two sealing structures are subjected to external forces approaching each other.

[0006] By adopting the above-mentioned technical solution, the present application utilizes that when the door panel moves upward to the open position during drainage, the sealing structures are subjected to an external force that moves them closer to each other. In this case, the sealing structures will not abut the other walls or structures used for sealing at the side ends of the door panel with the tightest force, thereby making it easier for the door panel to move upward, and the resistance encountered during the upward movement is reduced. When the staff opens the gate, whether it is opened manually or by external input drive, it will be easier. The present application also utilizes that when the door panel moves down to the closed position, the two sealing structures are subjected to an external force that moves them away from each other. In this case, the two sealing structures will further strengthen the sealing structure and the wall or structure used for sealing at the side ends of the door panel when they are already abutting or tightly against the side ends of the door panel, thereby better ensuring the sealing effect of the door panel when drainage is not being performed. Therefore, when the door panel moves, the present application causes the sealing structure to abut the wall used for sealing with a normal force or a force less than normal. Moreover, when the door panel is in the closed position, the driving member and the transmission member are arranged to further increase the contact force between the sealing structure and the wall. Thus, during normal use, if the sealing structure is worn out after use, the contact force can be further increased to better ensure the normal use of the door panel and better ensure that the door panel can support multiple drainage operations.

[0007] Preferably, the sluice drainage system also includes: a connecting member; the connecting member connects the driving member with the transmission member; the driving member drives the door panel to move up and down through the connecting member; when the driving member drives the connecting member to move up, the transmission member causes the two sealing structures to be subjected to an external force approaching each other, and then the door panel moves up to an opening position; when the driving member drives the connecting member to move down, after the door panel moves down to a closing position, the transmission member causes the two sealing structures to be subjected to an external force moving away from each other.

[0008] By adopting the above technical solution and utilizing the setting of the connecting member, the driving member drives the door panel to move up and down through the connecting member while also realizing that the two sealing structures are subjected to external forces approaching each other and external forces moving away from each other.

[0009] Preferably, a sliding groove and an installation groove are provided in the door panel; the connecting member is provided in the installation 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 connecting member, so that when the connecting member moves upward, the two sealing structures are subjected to an external force moving closer to each other through the transmission member, and when the connecting member moves downward, the two sealing structures are subjected to an external force moving away from each other through the transmission member.

[0010] By adopting the above-mentioned technical solution and utilizing the arrangement of the sliding groove and the mounting groove, when the connecting member moves upward, the hinged connection between the transmission member and the guide rod causes the guide rod to apply an external force toward each other. However, when the connecting member moves downward to the gate-closing position, the hinged connection between the transmission member and the guide rod causes the two sealing structures to apply an external force away from each other. Therefore, without the need for an additional drive in the door panel, the two sealing structures can be subjected to external forces both toward each other and away from each other, thereby preventing damage to the drive device that would otherwise be difficult to repair and preventing heat dissipation problems from occurring.

[0011] Preferably, the transmission member includes a connecting rope and a guide wheel; the guide wheel is arranged 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 member is arranged in the sliding groove, and the elastic member is used to make the two sealing structures subject to external force away from each other.

[0012] By adopting the above-mentioned technical solution and utilizing the arrangement of the connecting rope and the guide wheel, when the connecting member moves upward, the connecting member can first be moved. Then, the connecting member pulls the sealing structure via the connecting rope, causing the two sealing structures to be subjected to a certain external force moving closer to each other. After this, the connecting member drives the door panel upward. Conversely, when the connecting member moves downward to its lowest position, the connecting member continues to move downward, and the connecting rope no longer pulls the sealing structure. As a result, the two sealing structures are subjected to an external force moving away from each other under the action of the elastic member. Therefore, utilizing the arrangement of the connecting rope and the guide wheel further simplifies the internal structure of the door panel, and when the two sealing structures are subjected to external forces moving closer to each other or moving away from each other, it is better to prevent the internal structure of the door panel from being damaged and requiring repair.

[0013] Preferably, the connecting member has a counterweight structure; the connecting member is slidingly connected to the mounting groove; a first abutment portion is provided at the top of the mounting groove, and a second abutment portion is provided at the top of the connecting member; the second abutment portion is used to abut against the first abutment plate.

[0014] By adopting the above technical solution, when the driving member drives the connecting member up and down using the rope, the counterweight structure can be used to press the connecting member against the door panel, so that the door panel itself has sufficient gravity to be waterproof. The first abutment portion on the mounting groove and the second abutment portion on the connecting member are used to enable the connecting member to drive the door panel to move upward.

[0015] 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 parts, and the pressure control mechanism applies external force to multiple parts on the rubber strip through the multiple external force control parts to make the rubber strip fit the wall or structure used for sealing.

[0016] By adopting the above technical solution, because in some cases, the wall or structure used for sealing cannot completely match the side end of the door panel, a rubber strip is used to fill the space between the side end of the door panel and the wall or structure used for sealing. However, due to construction errors, temperature differences, or service life, the wall or structure used for sealing and the side end of the door panel may not match to a large extent. Normal rubber strips will not be able to completely fill the seal, and thicker rubber strips will cause greater friction between the side end of the door panel and the wall or structure used for sealing, which will not only make it difficult to install but also hinder the upward and downward movement of the door panel. Therefore, the present application utilizes the setting of a pressure control mechanism to apply external force to rubber strips at different positions, so that rubber strips of normal thickness can also better fit the wall or structure used for sealing, better ensuring normal use and sealing effect.

[0017] 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 locations, and the pressure control mechanism applies external force to multiple locations on the rubber strip through the multiple external force control locations to make the rubber strip conform to the wall or structure to be sealed. The rubber strip is capable of deformation, so that the rubber strip can fill any position of the wall or structure to be sealed.

[0018] Preferably, the pressure control mechanism comprises: at least two mounting plates; the rubber strips are arranged on at least two of the mounting plates; and the number of the guide rods and the transmission members is the same as the number of the mounting plates.

[0019] Preferably, a embedding groove is further provided at the side end of the door panel, the mounting plate is located in the embedding groove, and the mounting plate abuts against the inner wall of the embedding groove; the setting direction of the protrusion is perpendicular to the side end of the door panel.

[0020] Preferably, a plurality of protrusions are provided on the embedding groove, a plurality of recesses are provided on the mounting plate, and the protrusions are inserted into the recesses.

[0021] Preferably, a silt removal structure is provided on the upstream side of the door panel; the silt removal structure is used to clean the silt at the upstream connecting section.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When draining water, when the door panel moves upward to the gate opening position, the sealing structure is subjected to external forces approaching each other. Then the sealing structure will not abut against other walls or structures used for sealing at the side ends of the door panel with the tightest force, thereby making it easier for the door panel to move upward, and the resistance encountered during the upward movement is reduced. When the staff opens the gate, it will be easier to open the gate whether manually or by external input drive. Then the sealing structure will not be easily damaged when it abuts against other walls or structures used for sealing.

[0023] 2. When the door panel moves down to the closed position, the two sealing structures are subjected to external forces moving away from each other. Then, the two sealing structures will further strengthen the sealing structure and the wall or structure used for sealing at the side end of the door panel when they are originally in contact or pressed against the side end of the door panel, so as to better ensure the sealing effect of the door panel when drainage is not in progress.

[0026] The following is combined with Figure 1-14 This application is described in further detail.

[0027] A sluice drainage system is provided between an upstream connecting section and a downstream connecting section.

[0028] Example 1:

[0029] Refer to the attached Figure 1-3 8. The sluice drainage system includes: a door panel 1, a bottom plate 2, a driving part 3 and a transmission part 4.

[0030] The door panel 1 is positioned between the breast wall and the gate piers, with sealing structures 5 installed on both sides. The breast wall is located above the gate piers, of which there are multiple. The door panel 1 is located between any two gate piers and below the breast wall. Above the breast wall is the lock chamber, which houses the components that control the opening and closing of the door panel 1, such as the actuator 3. The breast wall, gate piers, and lock chamber are all existing technologies and will not be discussed in detail.

[0031] A sealing wall directly provided on the gate piers cooperates with the sealing structure 5 to seal the door panel 1 between any two gate piers, separating the upstream connecting section from the downstream connecting section. Alternatively, a sealing structure provided on the gate piers seals the door panel 1 against any two gate piers, separating the upstream connecting section from the downstream connecting section. The sealing structure can be a straight plate or a grooved plate.

[0032] A bottom plate 2 is disposed between the upstream and downstream connecting sections and is positioned below the door panel 1. The door panel 1 abuts the bottom plate, separating the upstream and downstream connecting sections. A driving member 3 is used to move the door panel 1 upward to an open position and downward to a closed position. The open position is when the door panel 1 is away from the bottom plate, while the closed position is when the door panel 1 abuts the bottom plate.

[0033] The transmission member 4 is used to connect the two sealing structures 5 with the driving member 3 . The driving member 3 also causes the two sealing structures 5 to be subjected to external forces that move them closer to each other and to external forces that move them away from each other through the transmission member 4 .

[0034] When the door panel 1 is in the closed position, the two sealing structures 5 are subjected to an external force moving away from each other. When the door panel 1 moves down to the closed position, the two sealing structures 5 are subjected to an external force moving away from each other. Then, the two sealing structures 5 will further strengthen the sealing between the sealing structures 5 and the wall or structure at the side of the door panel 1, which is already in contact or tight contact with the side of the door panel 1. This can better ensure the sealing function of the door panel 1 when drainage is not in progress.

[0035] Refer to the attached Figure 1-3 , 8-10, when the door panel 1 is between the opening position and the closing position, the two sealing structures 5 are subjected to external forces approaching each other; in the process of the door panel 1 moving upward to the opening position, the sealing structures 5 are subjected to external forces approaching each other, then the sealing structures 5 will not abut against other walls or structures used for sealing at the side ends of the door panel 1 with the tightest force, thereby making it easier for the door panel 1 to move upward, and the resistance encountered during the upward movement is reduced, and when the staff opens the gate, it will be easier to open the gate whether it is manually opened or driven by external input.

[0036] Therefore, in the present application, when the door panel 1 is moving, the sealing structure 5 abuts against the wall used for sealing with a normal force or a force less than normal. Moreover, when the door panel 1 is in the closed position, the driving member 3 and the transmission member 4 are arranged to further increase the abutment force between the sealing structure 5 and the wall. Thus, in normal use, even if the sealing structure 5 is worn after use, the abutment force can be further increased to better ensure the normal use of the door panel 1 and better ensure that the door panel 1 can support multiple drainage operations.

[0037] In some possible implementations, the driving member 3 directly adopts two groups of driving, one of which is used to drive the upward and downward movement of the door plate 1, such as a hydraulic cylinder, a winch or a screw structure. The other group of driving is directly used to drive the mutual approaching movement or mutual moving away movement of the two sealing structures 5, wherein the movement of the sealing structure 5 refers to the movement trend, and the sealing structure 5 does not necessarily have a significant displacement, but this group of driving can provide the corresponding movement trend for the sealing structure 5, so that the sealing structure 5 is subjected to the external force of mutual approaching or moving away, and better abuts against the wall or structure to be sealed. This group of driving, such as a hydraulic cylinder, an air cylinder or an electric cylinder. A plurality of groups of driving can be provided, so that the sealing structure 5 is subjected to more uniform force.

[0038] Embodiment 2:

[0039] The difference between embodiment 2 and embodiment 1 is that the water gate drainage system further comprises a connecting member 6. The connecting member 6 connects the driving member 3 and the transmission member 4. The driving member 3 drives the upward and downward movement of the door plate 1 through the connecting member 6. When the driving member 3 drives the upward movement of the connecting member 6, the transmission member 4 makes the two sealing structures 5 subjected to the external force of mutual approaching, and then the door plate 1 moves upward to the open gate position. When the driving member 3 drives the downward movement of the connecting member 6, the door plate 1 moves downward to the closed gate position, and then the transmission member 4 makes the two sealing structures 5 subjected to the external force of mutual moving away.

[0040] Referring to the accompanying drawings, Figure 8-10 The purpose of the embodiment is to combine the two groups of driving in embodiment 1 into one group, and to use the connecting member 6 to realize one group of driving, that is, to drive the upward and downward movement of the door plate 1, to apply the external force of mutual approaching to the sealing structure 5, and to apply the external force of mutual moving away. The water gate may exist for a long time without drainage, so as to avoid the situation that too much driving leads to difficult maintenance or aging damage. It can also avoid the situation that the driving is difficult to install.

[0041] Referring to the accompanying drawings, Figure 1-3 , 8-10, in one possible implementation of the connecting member 6 and the door plate 1, 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 within 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 provided at the edge of the door panel 1 and extends through the side end of the door panel 1. The connecting member 6 is provided in the mounting groove 12; a guide rod 7 is provided in the sliding groove 11, which is slidably connected to the sliding groove 11 and fixed to the sealing structure 5. The transmission member 4 is hingedly connected between the guide rod 7 and the connecting member 6. When the connecting member 6 moves upward, the two sealing structures 5 are subjected to an external force moving toward each other through the transmission member 4, and when the connecting member 6 moves downward, the two sealing structures 5 are subjected to an external force moving away from each other through the transmission member 4. The transmission member 4 is a hinged plate or rod, with one end of the transmission member 4 hingedly connected to the connecting member 6 and the other end of the transmission member 4 hingedly connected to the guide rod 7. Because two sealing structures 5 are provided, there are two guide rods 7 and two transmission members 4. Preferably, when the two sealing structures 5 are subjected to external forces moving away from each other, the two transmission members 4 and the two guide rods 7 are collinear. Specifically, the sliding groove 11 and the mounting groove 12 have a central clearance groove, which allows the transmission members 4 to move. Without an additional drive in the door panel 1, the two sealing structures 5 can be subjected to external forces moving toward each other and away from each other, preventing damage to the drive device that would otherwise be difficult to repair and preventing heat dissipation problems.

[0042] The connector 6 is a block structure, with a protruding structure provided on the inner wall of the mounting groove 12. As the connector 6 moves upward, it abuts the protruding structure. Continued upward movement of the connector 6 drives the door panel 1 upward. As the connector 6 moves downward until it abuts the bottom wall of the mounting groove 12, continued downward movement of the connector 6 drives the door panel 1 downward. Alternatively, as 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 the connector 6. This allows the upward and downward movement of the connector 6 to drive the upward and downward movement of the door panel 1.

[0043] Example 3:

[0044] The difference between Example 3 and Example 2 is that the transmission member 4 is replaced by a hinged plate or a rod and includes a connecting rope 41 and a guide wheel 42.

[0045] Refer to the attached Figure 11The transmission member 4 includes a connecting rope 41 and a guide wheel 42. The guide wheel 42 is arranged 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 to be connected to the connecting member 6. Among them, one end of the connecting rope 41 can be hinged or fixed to the guide rod 7, and the other end of the connecting rope 41 can be hinged or fixed to the connecting member 6. The upward movement of the connecting member 6 will pull the sealing structure 5 through the connecting rope 41, so that the sealing structure 5 is subjected to an external force approaching each other. The accurate movement process is: first move the connecting member 6, and then the connecting member 6 pulls the sealing structure 5 through the connecting rope 41, so that the two sealing structures 5 are subjected to a certain external force approaching each other, and then 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 than the hinged cooperation of the hinged plate or rod, and is less likely to cause problems. An elastic member 43 is provided in the sliding groove 11. The elastic member 43 is used to force the two sealing structures 5 to move away from each other. The precise movement process is as follows: when the connecting member 6 moves downward to the lowest position, the connecting member 6 continues to move downward, and the connecting rope 41 no longer pulls the sealing structures 5. As a result, the two sealing structures 5 are subjected to an external force moving away from each other under the action of the elastic member 43. Therefore, the provision of the connecting rope 41 and the guide wheel 42 further simplifies the internal structure of the door panel 1. When the two sealing structures 5 are subjected to an external force moving toward each other or moving away from each other, damage to the internal structure of the door panel 1 and the need for repair are better avoided.

[0046] Example 4:

[0047] The difference between the fourth embodiment and the above embodiments is that the driving member 3 drives the gate to move up and down by using the rope 82 to pull the gate up and by using the gate's own weight to move the gate down.

[0048] Refer to the attached Figure 11 , the connecting member 6 has a counterweight structure, that is, the connecting member 6 has a larger gravity. The connecting member 6 is slidably connected to the mounting groove 12; a first abutting portion 121 is provided at the top of the mounting groove 12, and a second abutting portion 61 is provided at the top of the connecting member 6. The second abutting portion 61 is used to abut against the first abutting plate. Both the first abutting portion 121 and the second abutting portion 61 are flat plates. When the driving member 3 uses the rope 82 to drive the connecting member 6 to move up and down, the setting of the counterweight structure can be utilized to make the connecting member 6 press on the door panel 1, so that the door panel 1 itself has enough gravity for waterproofing. The first abutting portion 121 on the mounting groove 12 and the second abutting portion 61 on the connecting member 6 are for realizing that the connecting member 6 drives the door panel 1 to move up.

[0049] Refer to the attached Figure 4-614. The sealing structure 5 in the above embodiment may include a retaining plate 51 and a sealing rubber 52. A retaining groove 53 is provided at the side end of the door panel 1. The retaining plate 51 is inserted into 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 to be sealed.

[0050] Refer to the attached Figure 4-6 , two sealing rubbers 52 are provided on a card board 51, respectively located on the two side surfaces of the card board 51. One of the sealing rubbers 52 protrudes outward relative to the card board 51, and a first through hole 521 is provided in the middle of the sealing rubber 52, and a groove 522 is provided on the side of the sealing rubber 52. The groove 522 refers to the surface formed by cutting off a part 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 portion 526 can be further provided in the first through hole 521, and the fixing portion 526 is used to be fixed to the inner side of the first through hole 521, so as to avoid the part of the sealing rubber 52 at the position of the first through hole 521 from being deformed excessively to the outside, which may lead to failure. The fixing portion 526 can also abut against the wall or structure used for sealing to achieve multiple sealing, refer to the accompanying drawings Figure 14 . Another sealing rubber 52 protrudes outward relative to the card plate 51, and a second through hole 523 is provided in the middle of the sealing rubber 52, so that the sealing rubber 52 has better deformation and abuts against the wall or structure used for sealing. A first support portion 524 and a second support portion 525 are fixedly provided on the card plate 51, and the sealing rubber 52 at this position is located between the first support portion 524 and the second support portion 525. In addition, the sealing rubber 52 has a connecting portion and a head portion, and the connecting portion is located between the first support portion 524 and the second support portion 525. The head portion is a cylindrical portion, and the head portion is tangent to the connecting portion, which can better make the sealing rubber 52 abut against the wall used for sealing. And under the action of the first support portion 524 and the second support portion 525, fatigue deformation of the entire head portion is prevented.

[0051] Example 5:

[0052] The difference between Example 5 and the above examples is that: Refer to the attached 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 locations, which apply external forces to multiple locations on the rubber strip 54 to force the rubber strip 54 to conform to the wall or structure being sealed. The rubber strip 54 can deform, allowing it to fill any position of the wall or structure being sealed.

[0053] By adopting the above technical solution, since in some cases the wall or structure used for sealing cannot completely match the side end of the door panel 1, a rubber strip 54 is used to fill in between the side end of the door panel 1 and the wall or structure used for sealing. However, due to construction errors, temperature differences, or service life, the wall or structure used for sealing and the side end of the door panel 1 may not match to a large extent. Normal rubber strips 54 will result in an inability to completely fill the seal. Thicker rubber strips 54 will result in greater friction between the side end 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, the present application utilizes the setting of a pressure control mechanism to apply external force to the rubber strips 54 at different positions, so that rubber strips 54 of normal thickness can also better fit on the wall or structure used for sealing, better ensuring normal use and sealing effects.

[0054] In a first possible implementation of the pressure control mechanism, the pressure control mechanism includes: at least two mounting plates 55; the rubber strips 54 are disposed on at least two of the mounting plates 55; and the number of the guide rods 7 and the transmission members 4 is the same as the number of the mounting plates 55. A recess 56 is defined on the end of the door panel 1, into which the mounting plates 55 are embedded. The driver 3 applies an external force to the mounting plates 55 via the transmission member 4, and the mounting plates 55 then apply the external force to the rubber strips 54, which further press against the wall or structure being sealed. The provision of at least two mounting plates 55 and the simultaneous application of external force by the guide rods 7 to the at least two mounting plates 55 can cause the rubber strips 54 on each mounting plate 55 to deform and better match the wall or structure being sealed.

[0055] In some specific cases, the embedding groove 56 is provided with a plurality of protrusions, and the mounting plate 55 is provided with a plurality of recesses, into which the protrusions are inserted; the protrusions are arranged perpendicular to the side of the door panel 1. The protrusions and recesses guide the mounting plate 55.

[0056] Refer to the attached Figure 13In addition, in a second 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. The hydraulic bladder 58 is deformable, and its shape matches the wall or structure being sealed, thereby better deforming the rubber strip 54 and matching the wall or structure being sealed. The hydraulic bladder 58 can also be connected to an external hydraulic device to actively control the pressure of the hydraulic bladder 58.

[0057] In some other embodiments of the connector 6, the mounting slot 12 is a through slot. The lower end of the connector 6 is made of magnetic material. An electromagnet is disposed below the base plate 2. When the connector 6 moves downward to the gate closing position, the connector 6 and the base plate 2 engage, providing greater downward force for the connector 6 and ensuring the stability of the gate closing. A third abutment 62 is disposed at the lower end of the connector 6, and a fourth abutment 122 is disposed in the mounting slot 12. After the connector 6 moves downward to abut the third abutment 62 against the fourth abutment 122, continued downward movement of the connector 6 will exert downward pressure on the door panel 1.

[0058] In some other embodiments, Refer to the attached Figure 1 A dredging structure 8 is provided on one side of the upstream connecting section of the door panel 1, and 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 combining component and a second combining component. The first combining component connects one side of the net body 81 to the door panel 1, and the second combining component is connected to the other side of the net body 81. A winch is provided in the gate chamber, and the second combining component is connected to the winch through a rope 82. There can be multiple winches, some of which are used to control the opening of the door panel 1, and the other part of the winches are used to connect to the rope 82. The first combining component includes a plurality of connecting buckles, and the plurality of connecting buckles are arranged obliquely on the door panel 1. At least two winches connected to the second combining component are provided, and the rope 82 is connected to both ends of the second combining component. The second combining component adopts a connecting buckle, and at least two winches can control the length of the wound rope 82 to arrange the second combining component along an oblique arrangement. Then, the second connecting member can be moved upward by a winch, tilting the net 81. This allows the silt on the net 81 to drain to the side of the door panel 1. A collection tool can then be used to collect the silt at the side of the door panel 1, thereby better protecting the downstream environment.

[0059] The desilting structure 8 may further 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 is directed outward. The control valve is located at the end of the suction pipe directed outward. The control pump extracts the silt on the water surface along with some of the water, thereby achieving desilting. Preferably, the silt and water are discharged into a collection tank. A sewage purifier is provided in the collection tank, and the purified water is then discharged into the upstream connection section. Preferably, the water is discharged near the rubber strip 54.

[0060] In some other embodiments, a mesh 81 can also be installed on the side of the door panel 1 located at the downstream connection section. One end of the mesh 81 is connected to the side of the door panel 1 located at the downstream connection section, and the other end is connected to the underwater bottom of the downstream connection section. When the door panel 1 is opened, the mesh 81 will spread out under the door panel 1 to intercept some silt, such as tree branches, thereby better protecting the downstream environment.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
