Description

Technical Field

[0001] The present application relates to the technical field of sluice gates, and in particular to an anti-seepage enclosure structure for a sluice gate foundation in a water conservancy and irrigation project. Background Art

[0002] In water conservancy and irrigation projects, for example, when crops need to be watered in the dry season, the stored water needs to be released, so the corresponding sluice gates need to be opened to allow water to flow into the downstream area to provide water for the crops. Therefore, in water conservancy and irrigation projects, the sealing of the sluice gates is crucial. Existing sluice gates generally use rubber sealing methods, and seals are achieved by installing rubber strips on one side of the gate. Although this sealing method can meet the sealing requirements, during the movement of the gate, the friction between the sealing strip and the gate pier is large, which can easily wear the sealing strip. When the gate is used for a long time, the sealing effect gradually decreases, which makes it easy to leak. The sealing effect of the existing sluice gates decreases significantly with long-term use, and the sealing strips need to be replaced regularly, and the service life is low.

[0003] Therefore, the present invention proposes an anti-seepage enclosure structure for a sluice foundation of a water conservancy and irrigation project. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figure 1 - Fig.11 As shown, an anti-seepage enclosure structure for a water gate foundation of a water conservancy irrigation project proposed in an embodiment of the present application includes a gate pier 1, a gate 2 and a motor. The two inner sides of the gate pier 1 in the length direction are vertically provided with sliding grooves 14, and the gate 2 is slidably installed in the two sliding grooves 14. Specifically, a sealing strip is installed at the bottom end of the gate 2, and further includes:

[0036] The enclosure 3 includes two blocking blocks 301. Two mounting grooves 302 are provided on opposite sides of the sliding groove 14. The two blocking blocks 301 are respectively horizontally slidably installed in the two mounting grooves 302, and are used to contact one side of the gate 2.

[0037] A pressure component, comprising a pressure piece 4 and a pressure piece 5. The pressure piece 4 is installed on the side of the water-facing surface of the gate 2, and the pressure piece 5 is installed on the gate pier 1. When the pressure piece 4 is subjected to water pressure, the pressure piece 5 converts the water pressure into pressure of the two blocking blocks 301 on the gate 2. Specifically, the height of the blocking block 301 is higher than the height of the gate 2, ensuring that one side of the gate 2 can fully contact the blocking block 301. When the gate 2 is in a closed state, the gate 2 plays a role in blocking the water flow. At this time, part of the gate 2 is located below the water surface, which causes the pressure piece 4 to partially contact the water. The water pressure will apply a pressure to the pressure piece 4, and the pressure piece 5 will convert part of the water pressure received by the pressure piece 4 into pressure of the blocking block 301 on the gate 2. That is to say, the increase in water pressure can cause the blocking block 301 to move, thereby increasing the resistance force with one side of the gate 2, thereby improving the sealing effect;

[0038] Among them, a transmission member 7 acting on the gate 2 is installed on the gate pier 1. When the motor is started, the gate 2 can be driven to move through the transmission member 7. In this embodiment, the transmission member 7 can adopt the existing technical means of driving the gate 2;

[0039] The pressure relief mechanism 6 is installed on the gate pier 1 and acts on the pressure member 5. When the transmission member 7 drives the gate 2 to move, the pressure on the pressure member 5 is reduced through the pressure relief mechanism 6. That is to say, when the gate 2 in the closed state needs to be opened, the motor is started to drive the gate 2 to move upward through the transmission member 7. During this process, the pressure relief mechanism 6 releases the pressure applied by the pressure member 5 to the blocking block 301, thereby reducing the resistance between the blocking block 301 and the gate 2, so as to reduce the friction between the blocking block 301 and the gate 2, thereby effectively ensuring the moving life of the blocking block 301. When the gate 2 in the open state is closed, the pressure relief mechanism 6 is continuously in the pressure relief state when the gate 2 moves downward, thereby preventing the gate 2 from moving downward and causing excessive friction between the blocking block 301 and the gate 2. After the gate 2 is closed, the sealing strip at the bottom of the gate 2 contacts the gate pier 1. Under the action of water pressure, the blocking block 301 contacts the two sides of the gate 2 in opposite directions of the length direction, thereby ensuring the sealing effect and effectively preventing the possibility of leakage. Not only the sealing effect is ensured, but also the friction between the gate 2 and the blocking block 301 can be reduced when the gate 2 moves, thereby ensuring the service life.

[0040] like Figure 1 and Figure 5As shown, in some embodiments, the pressure member 4 includes a sliding cavity 401 opened on the plate surface of the gate 2, a pressure plate 402 is horizontally slidably installed in the sliding cavity 401, a spring telescopic rod 403 is installed between the pressure plate 402 and the sliding cavity 401, and an exhaust hole 404 is opened on the sliding cavity 401. The pressure member 5 acts on the pressure plate 402, and the spring telescopic rod 403 includes a sleeve installed in the sliding cavity 401, a sleeve rod is slidably installed in the sleeve, one end of the sleeve rod is connected to the pressure plate 402, a spring is installed between the sleeve and the sleeve rod, and a return convex edge is installed at one end of the pressure plate 402 A sealing ring can be installed on the outer side of the return convex edge to ensure sealing. The exhaust hole 404 is opened at the top of the sliding cavity 401 and passes through the top of the gate 2. This can effectively prevent water from entering the sliding cavity 401 from the exhaust hole 404. If water seeps into the sliding cavity 401, the design of the exhaust hole 404 can also ensure the movement of the pressure plate 402 and the spring telescopic rod 403, so the structure can be used in water. Preferably, in order to prevent the exhaust hole 404 from being blocked by external impurities, a filter plate can be installed on the exhaust hole 404 to prevent external impurities from entering the sliding cavity 401.

[0041] like Figure 1 , Figure 3 and Fig.10 As shown, in some embodiments, the pressure member 5 includes a pressure cylinder 501 and a connecting pipe 503 installed on the gate pier 1, a connecting pipe 502 is connected between the connecting pipe 503 and the pressure cylinder 501, a sliding rod 504 is slidably inserted at one end of the connecting pipe 503, and one end of the sliding rod 504 is connected to the blocking block 301, a moving column 505 is slidably installed in the pressure cylinder 501, and a linking member 8 is installed between the pressure plate 402 and the moving column 505. When the pressure plate 402 moves, the moving column 505 is moved through the linking member 8. When the pressure plate 402 moves downward due to the increase in water pressure, The moving column 505 will move downward through the connecting piece 8. The movement of the moving column 505 will squeeze the internal pressure of the pressure cylinder 501 into the connecting pipe 503 through the connecting pipe 502. Preferably, the inner diameter of the pressure cylinder 501 is much larger than the inner diameter of the connecting pipe 503. The Pascal principle is used to increase the force of the blocking block 301 against the gate 2, thereby further improving the sealing effect. It should be noted that when the moving column 505 moves, the pressure between the pressure cylinder 501 and the connecting pipe 503 will not cause the air inside the pressure cylinder 501 to be compressed, and the force that can compress the air is not reached.

[0042] like Figure 2 and Figure 7As shown, in some embodiments, the linkage 8 includes a connecting plate 802 installed on the pressure plate 402, a mounting plate 803 is configured at the top of the connecting plate 802, wedge plates 804 are configured at both horizontal ends of the mounting plate 803, a return spring 805 is installed between the moving column 505 and the bottom end of the pressure cylinder 501, a slot 806 is provided on one side of the pressure cylinder 501, a forcing inclined surface 801 is configured at the top of the moving column 505, the wedge plate 804 passes through the slot 806 and contacts with the forcing inclined surface 801, specifically, when the gate 2 is in a closed state, the inclined surface of the wedge plate 804 contacts with the forcing inclined surface 801, and the return spring 805 is in an uncompressed state, the wedge plate 804 moves upward to release the pressure relief mechanism 6 to release the internal air pressure of the pressure cylinder 501, that is, Specifically, when the pressure plate 402 moves into the sliding cavity 401 due to the water pressure, the movement of the pressure plate 402 will drive the connecting plate 802 connected thereto to move. The number of connecting plates 802 can be multiple, and the top ends are all connected to the mounting plate 803 to improve the connection strength. The pressure applied by the water pressure to the pressure plate 402 will cause the pressure plate 402 to move, because the inclined surface of the wedge plate 804 forces the inclined surface 801 to contact the moving column 505, thereby causing the moving column 505 to move downward to push the internal gas of the pressure cylinder 501 into the connecting pipe 503, thereby realizing the movement of the blocking block 301 to contact one side of the gate 2. The design of this structure not only does not affect the movement of the gate 2, but also enables the moving column 505 to move due to water pressure only when the gate 2 is in a closed state.

[0043] like Fig. 9 and Fig.10 As shown, in some embodiments, the pressure relief mechanism 6 includes a convex cylinder 601 connected to one side of the pressure cylinder 501, a ring plate 602 is configured inside the convex cylinder 601, a vent hole 603 is opened at the free end of the convex cylinder 601, a driving rod 604 is slidably inserted into the free end of the convex cylinder 601, and a blocking plate 605 for blocking the inner edge of the ring plate 602 is configured at one end of the driving rod 604 located inside the convex cylinder 601. A linkage assembly 9 acting on the driving rod 604 is installed on the gate pier 1. When the transmission member 7 is started, the driving rod 604 is moved far away through the linkage assembly 9. Move in the direction away from the vent hole 603, when the transmission member 7 is in the unactivated state, the blocking plate 605 blocks the inner edge of one side of the ring plate 602, that is, when the gate 2 is moving, the blocking plate 605 can no longer block the inner edge of the ring plate 602 under the drive of the linkage assembly 9, so that the convex cylinder 601 remains connected with the outside, thereby achieving the purpose of pressure relief, and when the gate 2 is in the two static states of closing and opening, the blocking plate 605 is blocked by the blocking ring plate 602, and the outside air cannot enter the convex cylinder 601, thereby ensuring the sealing.

[0044] like Figure 1 , Figure 3 , Figure 7 and Fig. 9As shown, in some embodiments, the linkage assembly 9 includes a transmission rod 901 hinged on the outside of the pressure cylinder 501, a movable groove 902 is opened on one side of the transmission rod 901, a column rod 903 located in the movable groove 902 is constructed at the end of the driving rod 604 located on the outside, a return spring 904 is installed between the blocking plate 605 and one end of the convex cylinder 601, a moving frame plate 905 is installed horizontally and slidably on the gate pier 1, and a linkage rod 906 is hinged between the moving frame plate 905 and one end of the transmission rod 901, and the transmission member 7 includes The gate 2 includes two threaded sleeves 701 that are rotatably mounted in the gate pier 1, and two driving screws 702 are installed on the top of the gate 2. The two driving screws 702 are respectively threadedly inserted in the two threaded sleeves 701. The motor has two output ends, which are respectively coupled with the two threaded sleeves 701. When the motor output shaft rotates, the threaded sleeves 701 rotate synchronously. A centrifugal driving member 10 is installed on the threaded sleeve 701. When the threaded sleeve 701 rotates, the centrifugal driving member 10 is used to move the movable frame plate 905, and the output shaft of the motor Two mutually meshing bevel gears are installed between the threaded sleeve 701. Specifically, a long groove is opened along the length direction of the driving screw 702, and the driving screw 702 is slidably installed on the gate pier 1. In this way, when the output shaft of the motor rotates to drive the threaded sleeve 701 to rotate, the two threaded rods will move upward. As the threaded rods move upward, the gate 2 connected thereto will move upward. The threaded sleeve 701 cooperates with the threaded rods to ensure the stability of the gate 2 when moving. In this process, the moving frame plate 905 will be moved by the centrifugal drive member 10, and the moving frame plate 905 will drive the connecting rod 906 hinged thereto to move. Because the other end of the connecting rod 906 is hinged on the transmission rod 901, the moving frame plate 905 will drive the transmission rod 901 to rotate through the connecting rod 906 when moving. As the transmission rod 901 rotates, the column 903 located in the movable groove 902 will move, thereby forcing the driving rod 604 to move in the direction away from the vent 603, so that the outside air can enter the pressure cylinder 501.

[0045] like Figure 6 and Fig.11As shown, in some embodiments, the centrifugal drive member 10 includes a slide 1001 installed in a circular array on the outer peripheral side of the threaded sleeve 701, and a push rod 1002 is slidably inserted on the outer peripheral side of the slide 1001. A connecting spring 1003 is installed between the push rod 1002 and the slide 1001. The connecting spring 1003 only plays a resetting role. When the threaded sleeve 701 does not rotate, the push rod 1002 is moved and reset by the connecting spring 1003. Specifically, the thread groove of the threaded rod is a fine pitch thread, so that the threaded sleeve 701 can rotate faster when the motor is started, and the stability of the gate 2 when moving can be ensured. When the threaded sleeve 701 is fast When rotating, the push rod 1002 will move away from the corresponding threaded sleeve 701 due to the action of centrifugal force, so that the push rod 1002 moves to the maximum limit position. As the threaded sleeve 701 continues to rotate, the push rod 1002 will contact the movable frame plate 905, thereby driving the movable frame plate 905 to move. The push rod 1002 can overcome the elastic force of the return spring 904 to drive the movable frame plate 905 to move, so that during the movement of the gate 2, it can effectively ensure that the inside of the pressure cylinder 501 is connected to the outside air, and no additional driving force or program is required to control when the movable frame plate 905 moves. The structure is simple and more convenient to use.

[0046] like Figure 1 , Figure 6 and Figure 7 As shown, in some embodiments, the free end of the push rod 1002 is constructed with an arc plate 1004, and the two ends of the multiple arc plates 1004 are fitted together to form a circle, and the outer arc surface of the arc plate 1004 is used to contact the movable frame plate 905. The design of the arc plate 1004 makes it possible for the push rod 1002 to move multiple outer arc plates outward due to the action of centrifugal force when the threaded sleeve 701 rotates, so that when the sliding sleeve continues to rotate, the contact time between the outer arc plate and the movable frame plate 905 can be guaranteed, and the pressure cylinder 501 can always maintain communication with the outside world during the movement of the gate 2, thereby effectively reducing the friction between the gate 2 and the blocking block 301 when the gate 2 moves.

[0047] like Figure 1 and Fig.10 As shown, in some embodiments, a sealing rubber plate 11 is installed on one side of the blocking block 301, and the sealing rubber plate 11 is used to contact one side of the gate 2. The material of the sealing rubber plate 11 can be rubber material, which effectively ensures the sealing effect and has good wear resistance.

[0048] like Figure 1 and Figure 4As shown, in some embodiments, a setting groove 12 is provided on the side of the gate 2 away from blocking the water flow, and a roller 13 is rotatably installed in the setting groove 12. A gap is left between the side of the gate 2 where the setting groove 12 is provided and the side of the sliding groove 14. The design of the roller 13 makes the gate 2 move more smoothly without affecting the sealing effect.

[0049] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
