Abstract
Description
Technical Field
[0001] This utility model relates to the field of seepage technology in hydraulic structures, and specifically to a drainage device for seepage points in hydraulic structures. Background Technology
[0002] During long-term operation, dams or hydraulic structures often experience various forms of seepage and leakage due to environmental factors and operational conditions, which can lead to cracks or even peeling of the plaster. Currently, the common method for addressing leakage in hydraulic structures is to use drainage systems to remove the leaking water from the structure.
[0003] Existing drainage devices generally include a water collector and a drainage pipe. Water leaking from a building's seepage point first accumulates to a certain amount on the wall surface, then slides down and falls onto the water collector, and is then discharged through the drainage pipe.
[0004] While this drainage method can drain leaking water from seepage points, it suffers from several drawbacks. First, the water accumulates on the wall until it reaches a certain volume before sliding down and draining, making the timing of drainage unpredictable. Second, the amount of water that accumulates and falls varies each time, resulting in an uncontrollable volume of water being drained. This affects the planning and efficiency of the overall drainage work, leading to unsatisfactory drainage results.
[0005] Meanwhile, with this drainage method, the leaked water will continue to accumulate at the leak point, and the leaked water may seep deeper into the wall, putting additional pressure on the building walls and causing further damage to the building. Utility Model Content
[0006] The technical problem to be solved by this utility model is to provide a drainage device for seepage points in hydraulic structures. The device uses an absorbent sponge to absorb the seepage water immediately, preventing the seepage water from accumulating and making it easier to control the timing and amount of drainage, and avoiding secondary damage to the hydraulic structures.
[0007] To address the aforementioned technical problems, the present invention provides a drainage device for leak points in hydraulic structures, comprising a drainage box, wherein the drainage box is provided with a water collection opening and a drainage outlet, the water collection opening is used to cover the leak point and be sealed and fixed to the hydraulic structure, the drainage outlet is connected to a drainage pipe, and an installation plate is provided inside the drainage box, wherein an absorbent sponge is provided on one side of the installation plate facing the water collection opening and a telescopic mechanism is provided on the other side, the telescopic mechanism is fixedly installed on the drainage box, and the telescopic mechanism can drive the installation plate to move toward the water collection opening.
[0008] Furthermore, the telescopic mechanism includes an electric push rod, which is fixedly disposed on the outer side of the drain box facing away from the water collection opening, and the telescopic end of the electric push rod extends into the drain box and is fixed to the mounting plate.
[0009] Furthermore, a reinforcing rib is fixedly connected between the telescopic end of the electric push rod and the mounting plate.
[0010] Furthermore, a guide rod is connected to the side of the mounting plate facing away from the water collection opening. One end of the guide rod facing away from the mounting plate passes through the side of the drain box facing away from the water collection opening and slides in cooperation with the drain box.
[0011] Furthermore, a limiting part is provided on the side of the guide rod facing away from the mounting plate, and the limiting part is in a stop-fitting cooperation with the side of the guide box.
[0012] Furthermore, multiple guide rods are arranged in a circular array along the telescopic direction of the telescopic structure.
[0013] Furthermore, the bottom of the absorbent sponge is positioned close to the drain outlet, and a drainage gap is provided between the sponge and the drain outlet.
[0014] Furthermore, the inner cavity of the drainage box has a square cross-section, and the cross-section of the absorbent sponge has a matching circle.
[0015] Furthermore, the drain outlet is designed to be coplanar with the lowest point and the leakage point of the absorbent sponge.
[0016] Furthermore, a rubber sealing strip is installed on the water collection opening of the drainage box, and an installation flange is provided on the outer periphery of the water collection opening.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] The following is an analysis of the beneficial effects of each claim:
[0019] (1) The water collection opening of the drainage box is sealed and fixed to the hydraulic structure. Leaking water can be discharged from the drainage port of the drainage box. By setting water-absorbing sponges and telescopic structures on both sides of the mounting plate, the telescopic structure can drive the water-absorbing sponge to fit against the leakage point of the hydraulic structure. The leakage water is absorbed and collected by the water-absorbing sponge. When the designated drainage time is reached, the telescopic structure moves towards the leakage point to compress the water-absorbing sponge. The leakage water flows into the drainage port from the bottom of the water-absorbing sponge, realizing regular drainage and making it easier to control the drainage time. At the same time, by using the absorption of the water-absorbing sponge, the amount of drainage each time can be controlled to a certain extent, ensuring the planning and efficiency of the overall drainage work.
[0020] Furthermore, by using absorbent sponges, water leaking from the leak point can be absorbed onto the sponge immediately, preventing the leaked water from accumulating at the leak point for a long time and preventing the leaked water from seeping deeper into the wall, thus avoiding further damage to the building.
[0021] (2) Using an electric push rod as a telescopic structure provides stable telescopic performance and facilitates automated control and remote operation, thus improving practicality.
[0022] (3) Adding reinforcing ribs can enhance the connection strength between the electric push rod and the mounting plate and improve stability.
[0023] (4) The side of the mounting plate facing away from the water collection opening is connected to a guide rod and slides with the drainage box. This ensures the smoothness of the mounting plate's movement when the telescopic mechanism moves it, preventing the mounting plate from shifting or shaking, and ensuring that the absorbent sponge is always aligned with the leakage point. At the same time, the guide rod can reduce the overall load of the telescopic structure and improve stability.
[0024] (5) The limiting part can prevent the telescopic mechanism from extending too far, avoid damage to the device, and also ensure that the movement range of the mounting plate is within a safe range.
[0025] (6) Multiple guide rods are arranged in a circular array along the telescopic direction of the telescopic structure, which can make the force on the mounting plate more uniform during the movement, and improve the stability and reliability of the device.
[0026] (7) The bottom of the water-absorbing sponge is set close to the outlet and a drainage gap is set between it and the outlet. This can minimize the gap between the water-absorbing sponge and the outlet, prevent too much water left by the water-absorbing sponge from remaining on the surface of the hydraulic structure, improve the drainage effect, and reduce damage to the hydraulic structure.
[0027] (8) The drain outlet is designed to be coplanar with the lowest point of the absorbent sponge and the leakage point. This allows the drain outlet to be positioned directly below the lowest point of the absorbent sponge, enabling the leakage water squeezed out of the absorbent sponge to flow quickly into the drain outlet and improve the drainage efficiency.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation Example 1:
[0034] like Figure 3 As shown, a leakage channel 13 is generated at the leakage point of the hydraulic structure 12, and the leakage channel 13 is located at the leakage point on the surface of the hydraulic structure 12.
[0035] refer to Figures 1 to 3 This utility model discloses a drainage device for seepage points in hydraulic structures (hereinafter referred to as the drainage device), comprising a drainage box 1, a water collection opening 15 and a drainage outlet 6. The water collection opening 15 is used to cover the seepage point and is sealed and fixed to the hydraulic structure 12. A drainage pipe 7 is connected to the drainage outlet 6. An installation plate 4 is provided inside the drainage box 1, and the installation plate 4 is arranged parallel to the water collection opening 15. An absorbent sponge 5 is provided on the side of the installation plate 4 facing the water collection opening 15, and a telescopic mechanism is provided on the other side. The telescopic mechanism is fixedly installed on the drainage box 1, and the telescopic mechanism can drive the installation plate 4 to move toward or away from the water collection opening 15.
[0036] This configuration, by sealing and fixing the water collection opening 15 of the drainage box 1 to the hydraulic structure 12, allows leaked water to be discharged from the drainage port 6 of the drainage box 1, thus achieving water diversion. By installing absorbent sponges 5 and telescopic structures on both sides of the mounting plate 4, in actual use, the telescopic structure can move the absorbent sponges 5 to adhere to the leak point of the hydraulic structure 12. The leaked water is absorbed and collected by the absorbent sponges 5. When the designated drainage time is reached, the telescopic structure moves towards the leak point, compressing the absorbent sponges 5, and the leaked water flows from the bottom of the absorbent sponges 5 into the drainage port 6, achieving regular drainage and facilitating control of the drainage timing. Simultaneously, the absorption of the absorbent sponges 5 allows for control over the drainage volume each time, ensuring the planning and efficiency of the overall drainage work.
[0037] Furthermore, by using the absorbent sponge 5, the water leaking from the leak point can be absorbed onto the absorbent sponge 5 immediately, preventing the leaked water from accumulating at the leak point for a long time and preventing the leaked water from seeping deeper into the wall, thus avoiding further damage to the building.
[0038] Specifically, in this embodiment, the telescopic mechanism includes an electric push rod 3, which is fixedly mounted on the outer side of the drain box 1 facing away from the water collection opening 15. The telescopic end of the electric push rod 3 extends into the drain box 1 and is fixed to the mounting plate 4. This configuration, using the electric push rod 3 as the telescopic structure, provides stable telescopic performance and facilitates automated control and remote operation, thus improving practicality.
[0039] Meanwhile, by placing the cylinder portion of the electric push rod 3 on the outer surface of the drain box 1, the depth of the drain box 1 can be relatively reduced, saving materials and facilitating processing and assembly. Furthermore, this avoids the electric connection portion of the cylinder of the electric push rod 3 being constantly exposed to the humid environment inside the drain box 1, ensuring its service life. In other embodiments, the telescopic mechanism can also be an electric cylinder or a rack and pinion mechanism, driving the mounting plate 4 to move towards or away from the water collection opening 15.
[0040] Preferably, in this embodiment, such as Figure 2 , 3 As shown, a reinforcing rib 10 is fixedly connected between the telescopic end of the electric actuator 3 and the mounting plate 4. A set of reinforcing ribs 10 is arranged on the upper and lower sides of the telescopic end of the electric actuator 3. This enhances the connection strength between the electric actuator 3 and the mounting plate 4, improving stability.
[0041] In this embodiment, a guide rod 11 is connected to the side of the mounting plate 4 facing away from the water collection opening 15. Multiple guide rods 11 are arranged in a circular array along the telescopic direction of the telescopic structure. The length direction of the guide rod 11 is parallel to the telescopic direction of the electric push rod 3. A matching guide hole is provided on the side of the drain box 1 facing away from the water collection opening 15, corresponding to the position of the guide rod 11. The end of the guide rod 11 facing away from the mounting plate 4 slides through the guide hole, achieving a sliding fit between the guide rod 11 and the drain box 1. This utilizes the guide rod 11 to ensure the smooth movement of the mounting plate 4 when the telescopic mechanism moves it, preventing the mounting plate 4 from shifting or shaking, ensuring that the absorbent sponge 5 is always aligned with the leakage point. Simultaneously, the guide rod 11 reduces the overall load on the telescopic structure and improves stability.
[0042] Preferably, in this embodiment, four guide rods 11 are arranged to ensure more even force distribution on the mounting plate 4 during movement. Of course, in other embodiments, the arrangement position and number of guide rods 11 can be set according to actual needs.
[0043] Preferably, in this embodiment, such as Figure 2 , 3As shown, a limiting part 14 is provided on the side of the guide rod 11 facing away from the mounting plate 4. The size of the limiting part 14 is larger than the size of the guide hole. In this way, when the electric push rod 3 moves, the limiting part 14 and the side of the guide box 1 are engaged to stop it. This can prevent the telescopic mechanism from extending excessively and avoid damage to the device, while also ensuring that the movement range of the mounting plate 4 is within a safe range.
[0044] Preferably, in this embodiment, such as Figure 1 , 3 As shown, the bottom of the absorbent sponge 5 is positioned close to the drain outlet 6, and a drainage gap is provided between the bottom of the absorbent sponge 5 and the drain outlet 6. This minimizes the gap between the absorbent sponge 5 and the drain outlet 6, preventing excessive water from remaining on the surface of the hydraulic structure 12, improving the drainage effect, and avoiding damage to the hydraulic structure 12.
[0045] Specifically, in this embodiment, the inner cross-section of the drainage box 1 parallel to the water collection opening 15 is square, and the cross-section of the absorbent sponge 5 parallel to the water collection opening 15 is a matching circle, with the circle located at the center of the square, and the size of the circle slightly smaller than the size of the inscribed circle of the square. The drainage port 6 is located at the middle of the bottom of the drainage box 1 on the side opposite to the water collection opening 15, and the drainage port 6 is coplanar with the lowest point of the absorbent sponge 5 and the leakage point. This arrangement allows the drainage port 6 to be positioned directly below the lowest point of the absorbent sponge 5, enabling the leakage water squeezed out from the absorbent sponge 5 to quickly flow into the drainage port 6, improving drainage efficiency.
[0046] like Figure 1 , 3 As shown, in this embodiment, a rubber sealing strip 9 is installed on the water collection opening 15 of the drainage box 1. A mounting flange 2 is provided on the outwardly turned edge of the water collection opening 15. Mounting holes 8 are provided at the four corners of the mounting flange 2. The mounting flange 2 is fixedly installed on the hydraulic structure 12 by fastening bolts (not shown in the figure) passing through the mounting holes 8. This facilitates the sealing and fixing of the drainage box 1 and the hydraulic structure 12. In other embodiments, sealant or similar materials can also be used to achieve the sealing between the water collection opening 15 and the hydraulic structure 12.
[0047] In this embodiment, the electric push rod 3 is controlled automatically by a controller. The controller's control circuit can be implemented by simple programming by those skilled in the art, and the power supply is also common knowledge in the art.
[0048] Preferably, in this embodiment, the drain pipe 7 is a telescopic pipe.
[0049] The working process of this application:
[0050] In use, the drain box 1 is fixed to the wall of the hydraulic structure 12, so that the water collection opening 15 of the drain box 1 is placed outside the leakage point of the hydraulic structure 12. The electric push rod 3 is activated by the controller to move the water-absorbing sponge 5 to fit against the wall at the leakage point of the hydraulic structure 12. The leakage water from the leakage point is directly absorbed by the water-absorbing sponge 5. The extension and retraction of the electric push rod 3 is set by the controller.
[0051] The extension and retraction interval of the electric push rod 3 is set according to the drainage time. When the set time is reached, the electric push rod 3 starts to extend and then retract. The extension of the extension rod of the electric push rod 3 drives the water-absorbing sponge 5 to move towards the wall of the hydraulic structure 12, so that the water-absorbing sponge 5 is squeezed between the wall and the mounting plate 4, and the water in the water-absorbing sponge 5 is squeezed out. The squeezed water is discharged from the drainage pipe 7 through the drainage port 6. Then the extension rod of the electric push rod 3 retracts and drives the water-absorbing sponge 5 to return to the wall at the leakage point of the hydraulic structure 12 to continue to absorb the leakage water. The electric push rod 3 repeatedly extends and retracts within the set time.
[0052] This eliminates the need for a long wait for water to accumulate on the walls of the hydraulic structure 12, making the drainage of water leaking from the leak points of the hydraulic structure 12 more effective.
[0053] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
[0054] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0055] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
