Description

Technical Field

[0001] This invention relates to a real-time seepage detection device for large-scale water conservancy projects that is easy to maintain for temperature sensors and can effectively block large water flows. Background Technology

[0002] Seepage refers to the flow of fluid in a porous medium, which is composed of granular or fragmented materials and contains many pores or fissures. In my country, dikes are generally built to block water flow to prevent sudden floods. However, the bottom of the dike is in contact with water for a long time, which can easily lead to seepage. Therefore, it is necessary to continuously inspect the dike.

[0003] Existing seepage detection devices mainly monitor seepage by embedding temperature sensors inside the dam and observing the instability of water temperature in the seepage zone. However, because the temperature sensors are embedded inside the dam, maintenance is inconvenient, which affects their lifespan and monitoring effectiveness. In addition, existing seepage detection devices lack seepage protection mechanisms, making it impossible to quickly intercept and protect the water flow when encountering large seepage. Currently, no effective solution has been proposed. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide a real-time seepage detection device for large-scale water conservancy projects, so as to facilitate real-time maintenance of temperature sensors and effectively intercept and protect against large water flows.

[0005] Technical Solution: The present invention discloses a real-time seepage detection device for large-scale water conservancy projects, comprising a hollow embedded frame. A top plate is detachably mounted on the top of the embedded frame. A placement groove communicating with the interior of the embedded frame is opened on the top of the top plate. A support frame is fixedly mounted at the bottom of the placement groove. An installation frame is mounted inside the placement groove and at the top of the support frame. Several installation rods are fixedly mounted at the bottom of the installation frame, extending into the embedded frame. Multiple water temperature sensors are fixedly mounted on one side of each installation rod, and flow velocity sensors are mounted on the other side of each installation rod between the multiple water temperature sensors. A lifting mechanism is provided at the top of the top plate, allowing the installation frame to move up and down, thereby moving the installation rods out of or into the embedded frame. A seepage protection mechanism is provided on the embedded frame. When the water flow increases, the openings on the front and rear side walls of the embedded frame can be reduced or closed, creating a certain obstruction to the water flow and preventing rapid seepage.

[0006] The lifting mechanism includes an inverted U-shaped fixing frame fixedly mounted on the top of the top plate. The inner walls of both sides of the inverted U-shaped fixing frame have mounting grooves, each containing a first lead screw. Both ends of the first lead screw are connected to the bearings of the inverted U-shaped fixing frame via first bearings. An L-shaped connecting frame, matching the mounting groove, is screwed to the outer wall of the bottom of the first lead screw. One side of the L-shaped connecting frame extends outside the mounting groove and is fixedly connected to the mounting frame. A synchronous drive assembly is located at the top of the first lead screw. The rotation of the first lead screw via the synchronous drive assembly drives the L-shaped connecting frame to move up and down along the first lead screw, thereby moving the mounting rod out of and into the pre-embedded frame. The L-shaped connecting frame has threaded holes matching the first lead screw, through which the first lead screw passes and is threadedly connected to the L-shaped connecting frame.

[0007] The synchronous drive assembly includes a first adjustment slot at the top of an inverted U-shaped fixing frame. A drive shaft is located in the middle of the first adjustment slot. The tips of two first lead screws extend into the first adjustment slot, and second transmission gears are fixedly mounted on the tips of the first lead screws. First transmission gears are fixedly mounted on the upper and lower outer walls of the drive shaft. The two second transmission gears are respectively connected to the corresponding first transmission gears via toothed belts. A first protective box is fixedly mounted at the top of the inverted U-shaped fixing frame. The drive shaft extends into the first protective box, and a first worm gear is fixedly mounted on the top of the drive shaft. A first servo motor is fixedly mounted on the inner side wall of the first protective box. A first worm is connected to the drive end of the first servo motor. One end of the first worm is connected to the bearing of the first protective box via a second bearing, and the first worm meshes with the first worm gear.

[0008] The seepage protection mechanism includes several protective plates installed on the front and rear sides of the pre-embedded frame. The protective plates are connected to the bearings of the pre-embedded frame via connecting shafts. A second adjustment groove is provided on the inner wall of one side of the pre-embedded frame. An inverted U-shaped moving frame is installed inside the second adjustment groove. The inverted U-shaped moving frame is connected to the top plate via a moving component. Several meshing teeth are fixed on the outer walls of both sides of the inverted U-shaped moving frame. One end of the connecting shaft extends into the second adjustment groove, and a driven gear matching the meshing teeth is fixed at the top of the connecting shaft. The inverted U-shaped moving frame moves up and down in the second adjustment groove via the moving component, thereby driving the meshing teeth to rotate, which in turn causes the connecting shaft to open or close the protective plates.

[0009] The movable component includes a second protective box located on one side of the top of the top plate. A second servo motor is located on the side wall of the second protective box, and a second worm gear is connected to the drive end of the second servo motor. One end of the second worm gear is connected to a bearing in the second protective box via a third bearing. A second lead screw is fixedly located at the top of the "inverted U-shaped" movable frame, and the top of the second lead screw extends into the interior of the second protective box. A rotating sleeve is fitted onto the top of the second lead screw, and a second worm wheel that meshes with the second worm gear is fitted onto the outside of the rotating sleeve. By controlling the second servo motor, the rotation of the second worm gear and the second worm wheel is controlled, thereby driving the movable frame to move up and down, thus opening or closing the protective plate. A guide block is fixedly located inside the "inverted U-shaped" movable frame, and multiple guide slides penetrating the guide block are located at the bottom of the second adjusting groove. The guide block can slide up and down along the guide slides.

[0010] The inverted U-shaped mounting frame has inclined mounting plates on both upper sides, with photovoltaic panels fixed to the top of the mounting plates. Auxiliary support rods connected to the mounting plates are located on both sides of the inverted U-shaped mounting frame. The photovoltaic panels are electrically connected to the first and second servo motors, converting solar energy into electrical energy to power the first and second servo motors. The mounting rods, protective plates, guide slides, and meshing teeth are all present in quantities of two or more.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: (1) By setting up a lifting mechanism, the water temperature sensor can be quickly extracted from the inside of the dam when maintenance is required. At the same time, the lifting mechanism is easy and labor-saving to operate through the cooperation of the first screw, L-shaped connecting frame and synchronous drive assembly. (2) By setting up a seepage protection mechanism, when the seepage flow is large, the opening of the pre-embedded frame side wall can be sealed to form a certain obstruction to the water flow, prevent the water flow from seeping out quickly, and further improve its protective performance.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figure 1-8 As shown, the present invention discloses a real-time seepage detection device for large-scale water conservancy projects, comprising a hollow embedded frame 1. A top plate 2 (connectable via four corner screws) is detachably mounted on the top of the embedded frame 1. A placement groove 3, communicating with the interior of the embedded frame 1, is opened at the top of the top plate 2. A support frame 4 is fixedly mounted at the bottom of the placement groove 3. An mounting frame 5 is mounted in the placement groove 3, located at the top of the support frame 4. Several evenly distributed mounting rods 6, extending into the interior of the embedded frame 1, are fixedly mounted at the bottom of the mounting frame 5. Water temperature sensors 7, symmetrically arranged vertically, are fixed on one side of each mounting rod 6. Flow velocity sensors 38 are mounted on both sides of each mounting rod 6 between two water temperature sensors 7. A lifting mechanism is fixedly mounted at the top of the top plate 2. The mounting frame 5 can move up and down via the lifting mechanism, thereby moving the mounting rods 6 out of or into the embedded frame 1. A seepage protection mechanism is provided on the embedded frame 1. When the water flow increases, the opening of the seepage protection mechanism on the embedded frame 1 can be closed, forming a certain obstruction to the water flow and preventing rapid seepage.

[0024] The lifting mechanism includes an inverted U-shaped fixing frame 8 fixedly mounted on the top of the top plate 2. The inner walls of both sides of the inverted U-shaped fixing frame 8 have mounting grooves 9, and each mounting groove 9 contains a first lead screw 10 along its vertical direction. An L-shaped connecting frame 11, matching the mounting groove 9, is screwed to the outer wall of the bottom of the first lead screw 10. One side of the L-shaped connecting frame 11 extends outside the mounting groove 9 and is fixedly connected to the mounting frame 5. Both ends of the first lead screw 10 are connected to the bearings of the inverted U-shaped fixing frame 8 via first bearings. A synchronous drive assembly is provided at the top of the first lead screw 10. A threaded hole matching the first lead screw 10 is provided on the L-shaped connecting frame 11, through which the first lead screw 10 passes and is threadedly connected to the L-shaped connecting frame 11. The rotation of the first lead screw 10 via the synchronous drive assembly drives the L-shaped connecting frame 11 to move up and down along the thread, thereby moving the mounting rod 6 out of and into the pre-embedded frame 1. The height of the U-shaped fixing bracket 8 is greater than the length of the mounting rod 6, ensuring that the mounting rod 6 and the water temperature sensor 7 can be fully lifted above the embedded frame 1 and the top plate 2 under the drive of the first lead screw 10, facilitating personnel maintenance. The water temperature sensor 7 and the flow rate sensor 38 are connected to an external terminal for communication.

[0025] The synchronous drive assembly includes a first adjustment groove 12 at the top of an inverted U-shaped fixing frame 8. A drive shaft 13 is located in the middle of the first adjustment groove 12. The top ends of two first lead screws 10 extend into the first adjustment groove 12, and a second transmission gear 15 is fixedly mounted on the top end of each lead screw 10. A first transmission gear 14, symmetrically arranged vertically, is fixedly mounted on the outer wall of the drive shaft 13. Both second transmission gears 15 are connected to their corresponding first transmission gears 14 via toothed belts 16. A first protective box 17 is fixedly mounted at the top of the inverted U-shaped fixing frame 8 corresponding to the position of the drive shaft 13. The drive shaft 13 extends into the first protective box 17, and a first worm gear 20 is fixedly mounted on the top end of the drive shaft 13. A first servo motor 19 is fixedly mounted on the inner side wall of the first protective box 17. A first worm 18 is connected to the drive end of the first servo motor 19. One end of the first worm 18 is connected to the bearing of the first protective box 17 via a second bearing. The first worm 18 meshes with the first worm gear 20. By controlling the first servo motor 19 to drive the first worm gear 18 to rotate, the first worm wheel 20 can rotate in both left and right directions, thereby causing the drive shaft 13 to drive the second transmission gear 15 to rotate through the toothed belt 16, which in turn drives the first lead screw 10 to rotate, causing the L-shaped connecting frame 11 to move the mounting rod 6 up and down.

[0026] The seepage prevention mechanism includes several protective plates 21 evenly arranged on the front and rear sides of the pre-embedded frame 1. Adjacent protective plates 21 form flow openings when open. The protective plates 21 are connected to the pre-embedded frame 1 via a connecting shaft 22 and a bearing. A second adjusting groove 23 is provided on the inner wall of one side of the pre-embedded frame 1. An inverted U-shaped moving frame 24 is provided inside the second adjusting groove 23. The inverted U-shaped moving frame 24 is connected to the top plate 2 via a moving assembly. Several evenly distributed meshing teeth 25 are provided on the outer walls of both sides of the inverted U-shaped moving frame 24. One end of the connecting shaft 22 extends into the second adjusting groove 23, and several driven gears 26 matching the meshing teeth 25 are fixed at its top. The moving assembly includes a second protective box 27 provided on one side of the top of the top plate 2. A second servo motor 29 is provided on the inner side wall of the second protective box 27. A second worm gear 28 is connected to the drive end of the second servo motor 29. One end of the second worm gear 28 is connected to the bearing of the second protective box 27 via a third bearing. A second lead screw 32 is fixedly mounted at the top of the inverted U-shaped moving frame 24. The top of the second lead screw 32 extends into the interior of the second protective box 27. A rotating sleeve 30 is fixedly fitted onto the top of the second lead screw 32. The inner wall of the rotating sleeve 30 has a threaded hole that matches the second lead screw 32. The rotating sleeve 30 is threadedly connected to the second lead screw 32 through the threaded hole. A second worm wheel 31, which meshes with the second worm 28, is fixedly fitted onto the outside of the rotating sleeve 30. The connection and operation of the second worm 28, the second servo motor 29, and the second worm wheel 31 are exactly the same as those of the first worm 18, the first servo motor 19, and the first worm wheel 20. The inverted U-shaped moving frame 24 has symmetrically arranged guide blocks 33 fixed inside. The bottom of the second adjusting groove 23 has symmetrically arranged guide rods 34 that pass through both guide blocks 33. The guide blocks 33 have sliding holes that match the guide rods 34. By controlling the second servo motor 29 to drive the second worm gear 28 to rotate, the first worm wheel 20 drives the inverted U-shaped moving frame 24 to slide up and down on the guide rods 34 through the sliding holes of the guide blocks 33, thereby driving the connecting shaft 22 to rotate, thus opening and closing the protective plate 21. The maximum upward stroke of the U-shaped moving frame 24 is less than the distance from the top of the meshing teeth 25 to the bottom of the driven gear 26, ensuring that the meshing teeth 25 and the driven gear 26 remain engaged when the U-shaped moving frame 24 reaches its limit position.

[0027] The inverted U-shaped mounting frame 8 has symmetrically inclined mounting plates 35 on both upper sides, with photovoltaic panels 36 fixed to the top of each mounting plate 35. Auxiliary support rods 37, fixedly connected to the mounting plates 35, are also fixed to both sides of the inverted U-shaped mounting frame 8 to enhance the structural strength of the mounting plates 35. The photovoltaic panels 36 are electrically connected to the first servo motor 19 and the second servo motor 29, converting solar energy into electrical energy to power the first and second servo motors. By installing the photovoltaic panels 36, the dam can be self-sufficiently powered by solar energy when there is no external power supply, avoiding the need for laying long power lines and reducing construction difficulty and maintenance costs.

[0028] Workflow:

[0029] During monitoring, the pre-embedded frame 1 is installed inside the dam, keeping the top plate 2 fixed at the top of the dam. During seepage, the water flows through the flow openings before and after the pre-embedded frame 1. At this time, the water temperature sensor 7 monitors the water temperature. If the water temperature is unstable during seepage, the water temperature sensor 7 will send the water temperature fluctuation signal to an external terminal, which personnel can check in time. When maintenance of the water temperature sensor 7 is required, the first start servo motor 19 drives the first worm gear 18 to rotate, the first worm gear 18 drives the first worm wheel 20 to rotate, the first worm wheel 20 drives the drive shaft 13 to rotate, and the drive shaft 13 drives the two first transmission gears 14 to rotate synchronously. The toothed belt 16 drives two second transmission gears 15 to rotate, which in turn drives two first lead screws 10 to rotate. The two first lead screws 10 drive two L-shaped connecting frames 11 to move upward, which in turn drives the mounting frame 5 to move upward. The mounting frame 5 drives the mounting rod 6 to move upward, and the mounting rod 6 drives the water temperature sensor 7 to move upward to the outside of the dam for easy maintenance. By setting up a lifting mechanism, the water temperature sensor 7 can be quickly extracted from inside the dam when maintenance is required. At the same time, the lifting mechanism is simple and labor-saving to operate through the cooperation of the first lead screws 10, L-shaped connecting frames 11 and synchronous drive components.

[0030] When the seepage flow is large, the flow velocity sensor 38 will detect that the water flow velocity is too fast. At this time, the second servo motor 29 will be activated to drive the second worm gear 28 to rotate. The second worm gear 28 will drive the second worm wheel 31 to rotate. The second worm 31 will drive the rotating sleeve 30 to rotate. The rotating sleeve 30 is threadedly connected to the second lead screw 32, and the second lead screw 32 is fixedly connected to the "inverted U-shaped" moving frame 24. Therefore, it is guided and limited by the guide block 33 and the guide slide rod 34 and cannot rotate. So when the rotating sleeve 30 rotates, it drives the second lead screw 3... 2. Moving upwards, the second lead screw 32 drives the "inverted U-shaped" moving frame 24 to move upwards. The "inverted U-shaped" moving frame 24 drives multiple sets of driven gears 26 to rotate synchronously through meshing teeth 25. The driven gears 26 drive multiple sets of protective plates 21 to rotate to a vertical state through connecting shaft 22, which blocks the water flow to a certain extent. By setting a seepage protection mechanism, when the seepage flow is large, the opening on the pre-embedded frame 1 can be reduced or closed to block the water flow to a certain extent, prevent the water flow from seeping out quickly, and further improve its protective performance.

[0031] In summary, this invention, by setting up a lifting mechanism, allows for the rapid extraction of the water temperature sensor from inside the dam when maintenance is required. The lifting mechanism, through the cooperation of the first lead screw, L-shaped connecting frame, and synchronous drive assembly, is simple and labor-saving to operate. Furthermore, by setting up a seepage protection mechanism, when the seepage flow is large, the opening on the pre-embedded frame can be sealed, creating a certain obstruction to the water flow and preventing rapid seepage, thus further improving its protective properties.
