Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water retaining gate used in water conservancy project construction. Background Art
[0002] During the construction and operation of water conservancy projects, sluice gates are crucial hydraulic facilities. Their primary functions are to control the flow of water, regulate water levels, and meet the diverse needs of water conservancy projects, including flood control, irrigation, and power generation. With the continuous development of water conservancy projects, higher requirements are being placed on the performance and reliability of sluice gates. However, existing sluice gates used in water conservancy project construction still face some practical problems.
[0003] In water conservancy projects, floodgates often need to withstand high water pressure. When closed, they are subjected to immense pressure from the upstream water. When the gates need to be opened, the water pressure forces them to rise smoothly against significant resistance. This requires significant power, often requiring a high-power drive. This not only increases equipment procurement costs and operating energy consumption, but also places higher demands on infrastructure, such as power supply.
[0004] More critically, opening the gate under high water pressure causes significant wear and tear on the gate itself and its transmission mechanism. While bearing immense water pressure, the gate's structural components are subjected to intense compression and friction. This can easily lead to deformation and damage over time, impacting the gate's sealing performance and service life.
[0005] Secondly, the water flow often carries gravel and other foreign objects. When the gate is closed, these foreign objects tend to accumulate at the bottom of the gate, causing the gate to be unable to close completely, affecting the water retaining effect. Utility Model Content
[0006] In view of the above situation, in order to overcome the defects of the existing technology, the utility model provides a water retaining gate for water conservancy project construction, which effectively solves the problem that the water retaining gate usually needs to withstand a large water pressure, which easily causes large losses to the gate itself and the transmission mechanism when the gate is opened. Secondly, the water flow often carries gravel and the like. When the gate is closed, these foreign objects are easily accumulated at the bottom of the gate, resulting in the gate being unable to be completely closed, affecting the water retaining effect.
[0007] The technical solution provided by the utility model is a water retaining gate for water conservancy project construction, comprising a frame and a gate body slidably connected to the inside of the frame, wherein a linear drive device is provided on the frame to control the gate body to slide up and down within the frame, a plurality of vertically arranged reinforcing plates are fixedly mounted on one side of the gate body, and a plurality of vertically arranged pressure relief holes are opened between two adjacent reinforcing plates;

[0011] Preferably, the control structure includes limiting grooves provided on the two inner side walls of the frame, and the two ends of the gate body are respectively slidably connected to the inside of the limiting grooves;

[0018] The beneficial effects of the utility model are:
[0019] The utility model realizes the separation of the control shielding plate and the pressure relief hole by adding a pressure relief hole, a shielding plate, a control plate, a control frame, a sealing pressing shaft, a pressing slide groove, a limit groove, a guide block, a control slide block and a guide groove, so as to enable water to flow out through the pressure relief hole, thereby reducing the pressure of the water flow on the gate, thereby solving the problem that the water retaining gate usually needs to withstand a large water pressure, which easily causes large losses to the gate itself and the transmission mechanism when the gate is opened;
[0020] By adding a sliding block, a compression spring, a cleaning plate and a torsion spring, when the gate is closed, the gate body pushes the cleaning plate to swing away from the gate body, pushing the debris under the gate body away from the gate body, thereby solving the problem that gravel and other foreign objects are often carried in the water flow.

DETAILED DESCRIPTION
[0035] The technical solution of this embodiment will now be further described with reference to the accompanying drawings and embodiments.
[0036] Example 1, refer to the attached Figure 1-11 As shown, a water retaining gate for water conservancy project construction includes a frame 1 and a gate body 2 slidably connected to the inside of the frame 1. A linear drive device is provided on the frame 1 to control the gate body 2 to slide up and down inside the frame 1. In this embodiment, the linear drive device can adopt a hydraulic cylinder to push the gate body 2 to slide up and down inside the frame 1. A plurality of vertically arranged reinforcing plates 3 are fixedly installed on one side of the gate body 2. The strength of the gate body 2 is improved by providing the reinforcing plates 3. A plurality of vertically arranged pressure relief holes 4 are provided between two adjacent reinforcing plates 3. A plurality of shielding plates 5 for covering the pressure relief holes 4 are rotatably connected between two adjacent reinforcing plates 3. A rotating shaft is provided on the upper end of the shielding plate 5, and the rotating shaft is hinged on the reinforcing plate 3;
[0037] When in use, the gate body 2 is controlled to slide downward to close the gate, and part of the water flow can pass through the pressure relief hole 4 and through the gate body 2, thereby reducing the pressure of the water flow when closing the gate, making it easier for the gate body 2 to close. Subsequently, the shielding plate 5 is controlled to block the pressure relief hole 4, thereby completely cutting off the water flow. When opening the gate, the shielding plate 5 and the pressure relief hole 4 are first controlled to separate, and the gate body 2 is pulled upward. The water flow can pass through the pressure relief hole 4 and through the gate body 2, thereby reducing the pressure of the water flow when opening the gate, making it easier for the gate body 2 to open.
[0038] A control plate 6 is connected to the gate body 2 for sliding up and down movement. A slide groove is provided inside the gate body 2. The control plate 6 is connected to the slide groove for sliding up and down movement. A plurality of control frames 7 are fixedly connected to the lower end of the control plate 6. The control frames 7 are respectively arranged between two adjacent reinforcement plates 3. A plurality of sealing compression shafts 8 for pushing the masking plate 5 toward the direction of the pressure relief hole 4 are fixedly connected to the control frame 7. Compression slide grooves 9 slidably connected to the sealing compression shaft 8 are provided on both sides of the reinforcement plate 3.
[0039] When closing the gate, the gate body 2 first slides downward to the limit position, and then pushes the control frame 7 downward, and the sealing pressing shaft 8 slides inside the pressing chute 9. At the same time, the sealing pressing shaft 8 slides from the top of the shielding plate 5 to the bottom of the shielding plate 5, thereby pressing the shielding plate 5 in the direction of fitting the pressure relief hole 4, so that the shielding plate 5 blocks the pressure relief hole 4, thereby achieving the purpose of blocking water flow through the gate;
[0040] When opening the gate, first pull the control panel 6 upwards, and the control panel 6 drives the control frame 7 to slide upward synchronously. At this time, the sealing pressing shaft 8 slides from the bottom of the shielding plate 5 to the top of the shielding plate 5 until the sealing pressing shaft 8 and the shielding plate 5 are out of contact. Under the action of water pressure, the shielding plate 5 is pushed to swing on the reinforcing plate 3, so that the shielding plate 5 and the pressure relief hole 4 are separated. At this time, the water flows through the pressure relief hole 4 through the gate body 2, reducing the effect of water pressure on the gate body 2, making the gate body 2 easier to move upward, thereby reducing the loss to the device caused by pressure.
[0041] A control structure for controlling the sliding of the control plate 6 is provided inside the gate body 2 .
[0042] The control structure includes limit grooves 10 provided on the two inner side walls of the frame 1. The two ends of the gate body 2 are respectively slidably connected inside the limit grooves 10, thereby guiding the gate body 2 through the limit grooves 10;
[0043] Both ends of the control plate 6 are fixedly connected to a trapezoidal guide block 11, and both ends of the gate body 2 are slidably connected to a control slider 12 that cooperates with the guide block 11. Both ends of the gate body 2 are provided with a horizontally set limiting chute, and the control slider 12 is slidably connected to slide horizontally inside the limiting chute. The control slider 12 is set to a right-angled trapezoid;
[0044] A guide groove 13 is formed at the lower end of the limiting groove 10 to control the sliding block 12 to slide inside the gate body 2 .
[0045] The linear drive device includes a rotating disk 14 rotatably connected to the upper end of the frame 1, one end of a driving shaft 15 is fixedly connected to the control board 6, the other end of the driving shaft 15 is connected to one end of a threaded shaft 22, and the threaded shaft 22 is threadedly connected to the rotating disk 14.
[0046] When in use, the rotating disk 14 is rotated to control the longitudinal movement of the threaded shaft 22 on the frame 1, thereby controlling the gate body 2 to move up and down inside the frame 1 through the threaded shaft 22, thereby realizing the operation of closing or opening the gate. The rotating disk 14 can be connected to the rotating disk 14 by a motor and a chain to drive the rotating disk 14 to rotate, or the rotating disk 14 can be manually rotated to control the opening and closing of the gate.
[0047] When closing the gate, first push the push shaft 15 downward through the threaded shaft 22. When the gate body 2 moves downward, the inclined surfaces of the guide blocks 11 on both sides of the control plate 6 fit with the inclined surfaces of the control slider 12. The control slider 12 is pushed away from the gate body 2 by the guidance of the inclined surfaces. At this time, the end of the control slider 12 away from the gate body 2 fits with the limit groove 10. Figure 5 At this time, the control slider 12 is limited to the current position and cannot slide inside the limiting slide grooves opened on both sides of the gate body 2. At this time, the control slider 12 is close to the inclined surface of the guide block 11 and fits the inclined surface of the guide block 11, limiting the control plate 6 to the current position, thereby synchronously pushing the push shaft 15 downward by rotating the threaded shaft 22, and synchronously pushing the gate body 2 downward to the limit position through the control plate 6; at this time, after the control slider 12 slides to the position at the same height as the guide groove 13, the push shaft 15 continues to slide downward, thereby pushing The dynamic control plate 6 slides downward synchronously. At this time, the guide block 11 pushes the control slider 12 to slide away from the gate body 2 through the inclined guide until the end of the control slider 12 away from the gate body 2 is pushed into the inside. At the same time, the control plate 6 pushes the control frame 7 downward, and the sealing clamping shaft 8 slides inside the clamping groove 9. At the same time, the sealing clamping shaft 8 slides from the top of the shield plate 5 to the bottom of the shield plate 5, thereby pressing the shield plate 5 in the direction of the pressure relief hole 4, so that the shield plate 5 blocks the pressure relief hole 4, thereby achieving the purpose of blocking the water flow through the gate.
[0048] When the gate is opened, the pushing shaft 15 is pushed upward by the threaded shaft 22, and the control plate 6 is driven to slide upward synchronously by the pushing shaft 15. At this time, the sealing pressing shaft 8 slides from the bottom of the shield plate 5 to the top of the shield plate 5 until the sealing pressing shaft 8 and the shield plate 5 are out of contact. Under the action of water pressure, the shield plate 5 is pushed to swing on the reinforcing plate 3, so that the shield plate 5 and the pressure relief hole 4 are separated. When the control plate 6 slides upward to the limit position synchronously, the control plate 6 drives the gate body 2 to move upward synchronously. When the gate body 2 moves upward, the end of the control slider 12 away from the gate body 2 contacts the inclined surface of the guide groove 13. After being guided by the inclined surface of the guide groove 13, the control slider 12 is pushed in the direction close to the gate body 2, so that the inclined surface of the control slider 12 is fitted with the inclined surface of the guide block 11. The control slider 12 supports the guide block 11 in the current position. At this time, the end of the control slider 12 away from the gate body 2 is fitted with the limit groove 10, thereby fixing the control plate 6 in the current position.
[0049] The end of the control slider 12 away from the gate body 2 is rotatably connected to a roller 16, which is arranged to reduce the friction between the control slider 12 and the limiting groove 10, making it easier for the control slider 12 to slide inside the limiting groove 10.
[0050] A filling block 17 for blocking the pressure relief hole 4 is fixedly connected to one side of the shielding plate 5 close to the pressure relief hole 4. A rubber sealing gasket 18 is sleeved around the filling block 17 so that the shielding plate 5 blocks the pressure relief hole 4 and the rubber sealing gasket 18 improves the sealing effect.
[0051] Embodiment 2, on the basis of embodiment 1, both sides of the gate body 2 are slidably connected with sliding blocks 19, the sliding blocks 19 are slidably connected to the lower end of the gate body 2, and a compression spring 20 is connected between the sliding block 19 and the gate body 2. Vertical guide grooves are provided on both sides of the lower end of the gate body 2, and the sliding blocks 19 are slidably connected inside the vertical guide grooves. A cleaning plate 21 is rotatably connected to the sliding block 19, and a torsion spring is installed between the cleaning plate 21 and the sliding block 19. In the initial state, the cleaning plates 21 on both sides of the gate body 2 are pushed to rotate under the action of the torsion spring, so that the bottom ends of the two cleaning plates 21 are fitted together, and both sides of the lower end of the gate body 2 are provided with guide slopes that match the cleaning plates 21.
[0052] In the initial state, the sliding block 19 is pushed downward to the limit position by the action of the compression spring 20, and the cleaning plate 21 is fitted with the guide slope at the lower end of the gate body 2, thereby limiting the cleaning plate 21 to the current position, so that the bottom ends of the two cleaning plates 21 on both sides of the gate body 2 are fitted together;
[0053] When in use, when the gate body 2 is pushed to slide downward, the bottom ends of the two cleaning plates 21 first contact the bottom of the frame 1, and then continue to push the gate body 2 to slide downward. Under the action of the guiding inclined surface at the bottom of the gate body 2, the two cleaning plates 21 are pushed to swing away from each other, so that under the action of the cleaning plates 21, the debris under the gate body 2 is pushed away from the gate body 2 so that it does not affect the gate body 2 sliding downward to close the gate. When the gate body 2 slides downward, the gate body 2 pushes the cleaning plates 21 to move away from the gate body 2, and at the same time pushes the sliding block 19 upward to compress the compression spring 20 until the gate body 2 slides downward to the limit position;
[0054] When the gate body 2 is pushed to slide upward, the sliding block 19 is pushed downward to the limit position under the action of the compression spring 20, and the cleaning plates 21 on both sides of the gate body 2 are pushed to rotate under the action of the torsion spring, so that the bottom ends of the two cleaning plates 21 are fitted together.
[0055] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model. Therefore, the scope of protection of the present utility model should be based on the scope of protection of the claims.
