Description

Technical Field

[0001] The invention belongs to the technical field of reservoir leakage plugging, and in particular relates to a reservoir leakage plugging and drainage device. Background Art

[0002] The reservoir leak plugging and diversion device is an emergency rescue device used to quickly seal leaks and cracks in reservoirs, dams, or water conservancy projects. By combining plugging materials (such as polymer gels and quick-setting mortars) with diversion structures, it not only seals leaks but also guides water to safe passages, preventing the risk of dam failure. Suitable for use in earth-rock dams and concrete structures, it offers rapid response, efficient water-stopping, and flexible adaptability.

[0003] When reservoirs were built in some areas, caves connected to underground rivers formed on the ground. During the rainy season, these caves would flow into the reservoirs; however, during the dry season, these caves would drain the water away from the reservoirs. To prevent the backflow of water from the reservoirs, the caves were often filled with concrete or sandbags during reservoir construction. However, while this approach solved the problem of backflow, it also blocked the underground rivers from flowing into the reservoirs during the rainy season, preventing this water from naturally converging into the reservoirs. Subsequently, to meet the reservoir's water storage needs, water would need to be pumped in from outside sources, using electricity and other means. This not only increased costs but also hindered the effective use of natural resources. Summary of the Invention

[0004] In response to the problems in the related art, the present invention proposes a reservoir leak plugging and drainage device to overcome the above-mentioned technical problems existing in the existing related art.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a reservoir leak plugging and drainage device, comprising a drainage device main body, a leak plugging mechanism is arranged above the drainage device main body, the leak plugging mechanism comprises a fixed disk fixedly mounted on the drainage device main body, the fixed disk is provided with an arc-shaped slide groove, the interior of the arc-shaped slide groove is slidably connected with a protrusion, the protrusion is fixedly mounted on a sealing plate, the sealing plate is slidably connected to a rotating disk, the rotating disk is rotatably mounted on the drainage device main body, a first gear is fixedly mounted on the bottom of the rotating disk, the first gear is meshed with a second gear, the second gear is connected to a transmission mechanism, the transmission mechanism is used to drive the second gear to rotate, and a first water inlet is arranged below the drainage device main body.

[0007] Furthermore, a plurality of the arc-shaped chute, protrusion and sealing plate are provided, and their installation methods are the same, and the sealing plates are distributed in a ring array on the rotating disk.

[0008] Furthermore, the transmission mechanism includes a connecting shaft arranged on the second gear, one end of the connecting shaft is fixedly mounted on the second gear, the other end of the connecting shaft is rotatably mounted on the connecting plate, a worm wheel is fixedly mounted on the connecting shaft, the worm wheel is engaged with a worm, and the worm is rotatably mounted inside the drainage device body, and the transmission ratio of the worm and the worm wheel is 1:30.

[0009] Furthermore, the connecting plate is fixedly mounted inside the drainage device body, a third gear is fixedly mounted on one end of the worm, the third gear is meshed with a rack, the rack is fixedly mounted on the sealing plug through a connecting rod, the sealing plug is fixedly mounted on one end of the telescopic rod, the other end of the telescopic rod is fixedly mounted on the connecting plate, and the meshing length of the rack and the third gear is two-thirds of the total length of the rack.

[0010] Furthermore, a reset spring is provided on the outside of the telescopic rod, the sealing plug matches the second water inlet, the second water inlet is opened on the connecting plate, and the elastic coefficient of the reset spring is 50N / m.

[0011] Furthermore, a filter screen is fixedly mounted on the first water inlet, a rotating shaft is rotatably mounted on the filter screen, and a mesh diameter of the filter screen is 5 mm.

[0012] Furthermore, a cleaning brush is fixedly mounted on one end of the rotating shaft, and an impeller is fixedly mounted on the other end. The cleaning brush fits the outer surface of the filter plate, and the impeller is made of stainless steel.

[0013] Furthermore, the filter screen is fixedly connected to the drainage device body by a first bolt, and the drainage device body is fixedly connected by a second bolt, and the specifications of the first bolt and the second bolt are both M10×50.

[0014] The present invention has the following beneficial effects:

[0015] 1. By installing multiple sealing plates and utilizing the coordination of arc-shaped chutes and protrusions, the sealing plates can produce radial displacement as the rotating disk rotates, achieving both drainage and sealing functions. Simultaneously, the self-locking properties of the worm gear and worm ensure the stable position of the sealing plates. The synchronized movement of multiple sealing plates ensures uniform sealing, effectively preventing reservoir water backflow and improving the sealing performance of the device.

[0016] 2. The device automatically adjusts its sealing state based on changes in water pressure. When the reservoir water level rises and water pressure is generated, the water flow pressure pushes the sealing plug to move, and through a series of transmissions, the sealing plate expands outward to achieve drainage. When the water pressure decreases, the return spring pushes the sealing plug back to its original position, causing the sealing plate to retract inward, sealing the device automatically adapting to different water pressure conditions without manual intervention.

[0017] 3. A filter screen is installed at the first water inlet to effectively intercept impurities in the water. The water impacts the impeller, driving the rotating shaft, causing the cleaning brush to continuously clean the outer surface of the filter screen, preventing mesh clogging and ensuring unobstructed drainage. The filter screen and drainage device are secured with rust-proof bolts for easy disassembly and maintenance. The entire filtration process requires no external power, achieving a self-cleaning function.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the invention.

[0030] See also Figures 1-6 As shown, the present invention is a reservoir plugging and drainage device, including a drainage device main body 1, a plugging mechanism is arranged above the drainage device main body 1, the plugging mechanism includes a fixed plate 2 fixedly mounted on the drainage device main body 1, the fixed plate 2 is provided with an arc-shaped chute 3, the interior of the arc-shaped chute 3 is slidably connected with a protrusion 4, the protrusion 4 is fixedly mounted on a sealing plate 5, the sealing plate 5 is slidably connected to a rotating plate 6, the rotating plate 6 is rotatably mounted on the drainage device main body 1, a first gear 7 is fixedly mounted on the bottom of the rotating plate 6, the first gear 7 is meshed with a second gear 8, the second gear 8 is connected to a transmission mechanism, the transmission mechanism is used to drive the second gear 8 to rotate, and a first water inlet 9 is arranged below the drainage device main body 1.

[0031] The working principle of the reservoir leak plugging and drainage device proposed in this invention is as follows: first, a precast concrete foundation is constructed at the location corresponding to the drainage device body 1 at the cave entrance to ensure a stable installation foundation. After the drainage device body 1 is installed on the foundation, the device begins to operate when water in the cave rises and surges, generating upward pressure that attempts to enter the reservoir through the drainage device body 1.

[0032] Water flows into the drainage device body 1 through the first water inlet 9. At this point, the transmission mechanism rotates the second gear 8, which meshes with the first gear 7, driving the first gear 7 to rotate. The first gear 7 then rotates the rotating disk 6, causing the sealing plate 5 mounted on the rotating disk 6 to move accordingly.

[0033] The protrusion 4 on the sealing plate 5 slides along the arc-shaped chute 3 of the fixed plate 2. Due to the trajectory restriction of the arc-shaped chute 3, the sealing plate 5 gradually expands outward during the rotation process, thereby allowing water to flow into the reservoir.

[0034] It is worth noting that when the water in the cave is no longer rising and surging, there will be no water pressure, which will drive the transmission mechanism to move in the opposite direction, so that the sealing plate 5 gathers toward the center position of the fixed plate 2, thereby preventing the water in the reservoir from flowing back.

[0035] In one embodiment, for the above-mentioned arc-shaped chute 3 , a plurality of arc-shaped chute 3 , protrusion 4 and sealing plate 5 are provided, and their installation methods are the same. The plurality of arc-shaped chute 3 are evenly distributed along the circumference of the fixed plate 2 .

[0036] In one embodiment, for the above-mentioned transmission mechanism, the transmission mechanism includes a connecting shaft 10 arranged on the second gear 8, one end of the connecting shaft 10 is fixedly mounted on the second gear 8, and the other end of the connecting shaft 10 is rotatably mounted on the connecting disk 13. The connecting shaft 10 is fixedly mounted with a worm gear 11, and the worm gear 11 is engaged with a worm 12. The worm 12 is rotatably mounted inside the drainage device body 1, and the axis of the worm gear 12 is arranged perpendicular to the axis of the connecting shaft 10.

[0037] In one embodiment, for the above-mentioned connecting disk 13, the connecting disk 13 is fixedly installed inside the drainage device body 1, and a third gear 14 is fixedly installed at one end of the worm 12, and the third gear 14 is engaged with a rack 15. The rack 15 is fixedly installed on the sealing plug 16 through a connecting rod, and the sealing plug 16 is fixedly installed with one end of the telescopic rod 17, and the other end of the telescopic rod 17 is fixedly installed on the connecting disk 13. The movement direction of the rack 15 is parallel to the axis of the worm 12.

[0038] In one embodiment, for the above-mentioned telescopic rod 17, a reset spring 18 is provided on the outside of the telescopic rod 17, the sealing plug 16 matches the second water inlet 19, the second water inlet 19 is opened on the connecting disk 13, and one end of the reset spring 18 abuts against the sealing plug 16, and the other end abuts against the connecting disk 13.

[0039] The working principle of a reservoir leak plugging and drainage device proposed by the present invention is that after the drainage device body 1 is installed in place, when the water level in the reservoir rises and generates water pressure, the water flow pressure pushes the sealing plug 16 to move, and the sealing plug 16 drives the rack 15 to move linearly through the connecting rod. The rack 15 is engaged with the third gear 14, driving the third gear 14 to rotate. The third gear 14 is fixedly mounted on the worm 12, causing the worm 12 to rotate synchronously. The worm 12 drives the worm wheel 11 to rotate, and the worm wheel 11 drives the second gear 8 to rotate through the connecting shaft 10. The second gear 8 is engaged with the first gear 7, driving the first gear 7 to rotate, and the first gear 7 drives the rotating disk 6 to rotate. The rotating disk 6 drives multiple sealing plates 5 to move synchronously, and the protrusions 4 on the sealing plates 5 slide along the arc-shaped slide grooves 3 evenly distributed circumferentially on the fixed disk 2, causing the sealing plates 5 to produce radial displacement to achieve drainage.

[0040] When the water pressure decreases, the reset spring 18 mounted on the outside of the telescopic rod 17 releases its elastic potential energy, pushing the sealing plug 16 to reset. The sealing plug 16 drives the rack 15 to move in the opposite direction through the connecting rod. The rack 15 drives the third gear 14 to rotate in the opposite direction, thereby driving the worm 12, the worm wheel 11, the connecting shaft 10 and the second gear 8 to rotate in the opposite direction. The second gear 8 drives the first gear 7 to rotate in the opposite direction, causing the rotating disk 6 to rotate in the opposite direction. The rotating disk 6 drives the protrusion 4 on the sealing plate 5 to slide in the opposite direction along the arc-shaped slide groove 3, causing the sealing plate 5 to shrink inward, thereby sealing the top of the drainage device body 1 to prevent the water in the reservoir from flowing back. Throughout the process, the self-locking characteristics of the worm wheel 11 and the worm 12 ensure the positional stability of the sealing plate 5, and the synchronous movement of multiple sealing plates 5 ensures the uniformity of the seal, realizing the function of automatically adjusting the sealing state according to the change in water pressure.

[0041] In one embodiment, for the first water inlet 9 , a filter screen 20 is fixedly mounted on the first water inlet 9 , and a rotating shaft 21 is rotatably mounted on the filter screen 20 . The mesh size of the filter screen 20 is smaller than the diameter of the first water inlet 9 .

[0042] In one embodiment, for the above-mentioned rotating shaft 21, a cleaning brush 22 is fixedly installed at one end of the rotating shaft 21, and an impeller 23 is fixedly installed at the other end. The cleaning brush 22 fits the outer surface of the filter plate 20, and the blade direction of the impeller 23 is adapted to the direction of water flow.

[0043] In one embodiment, for the above-mentioned filter screen plate 20, the filter screen plate 20 is fixedly connected to the drainage device body 1 through a first bolt 24, and the drainage device body 1 is fixedly connected through a second bolt 25. The first bolt 24 and the second bolt 25 are both made of rust-proof material.

[0044] The working principle of the reservoir leak plugging and drainage device proposed in the present invention is that when water flows into the drainage device body 1 through the first water inlet 9, the water first passes through the filter screen 20 fixedly installed at the first water inlet 9. This effectively intercepts impurities in the water. The water impacts the impeller 23, causing it to rotate. The impeller 23 drives the rotating shaft 21 to rotate synchronously. The cleaning brush 22 at the other end of the rotating shaft 21 rotates accordingly and continuously cleans the outer surface of the filter screen 20 to prevent mesh clogging. The filter screen 20 is fixedly connected to the drainage device body 1 by a first bolt 24 to ensure structural stability. The drainage device body 1 is fixedly installed by a second bolt 25. Both the first and second bolts 24 and 25 are made of rust-resistant materials to adapt to underwater environments. When maintenance is required, the first bolt 24 can be removed to clean or replace the filter screen 20. The entire filtration process does not require external power and relies entirely on the water flow to drive the impeller 23 to achieve a self-cleaning function, ensuring a smooth drainage channel.
