Description

Technical Field

[0001] This utility model relates to the field of water conservancy and hydropower engineering technology, specifically a seepage prevention and water-stopping structure for water conservancy and hydropower engineering. Background Technology

[0002] Water conservancy and hydropower engineering mainly studies the basic knowledge and skills of water resources, hydraulic structures, hydraulics and fluid dynamics, and water conservancy engineering technology. It involves the surveying, planning, design, construction, and management of water conservancy and hydropower projects. In the dam engineering of water conservancy and hydropower, some dams are made of sandy clay and are prone to seepage. When the seepage exceeds a certain standard, it will affect the quality of the dam and greatly reduce its waterproof function. Therefore, it is necessary to set up seepage prevention and water-stopping structures on the dam to prevent water seepage.

[0003] Chinese Patent CN222730464U discloses a seepage-proof and water-stopping structure for water conservancy and hydropower projects, specifically relating to the field of water conservancy and hydropower engineering technology. It includes a foundation soil layer and a dam body located on top of the foundation soil layer. A water storage tank is fixedly installed on one side of the outer surface of the dam body, and multiple driving blocks are fixedly installed on the inclined side of the outer surface of the water storage tank. A sliding rod is fixedly installed inside each driving block. In practical operation, when water waves hit the buffer plate, the two support arms push the two moving blocks away from each other, causing the two moving blocks to compress two buffer springs. The elasticity of the buffer springs reduces the impact force of the water waves. The reinforcing ribs and reinforcing plates support the interior of the water storage tank during wave impact, thus facilitating buffering and preventing a shortened service life of the water storage tank due to wave impact.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the device is not easy to replace after the buffer plate is damaged, and it needs to be improved; therefore, in order to solve the above problems, a seepage prevention and water-stopping structure for water conservancy and hydropower projects is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the above-mentioned technical problems, this utility model proposes a seepage prevention and water-stopping structure for water conservancy and hydropower projects.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The seepage prevention and water-stopping structure for water conservancy and hydropower projects of this utility model includes a dam and a water storage tank.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6 As shown, a seepage-proof and water-stopping structure for water conservancy and hydropower projects includes a dam 1 and a water storage tank 2. A limiting groove 3 is formed in the lower side wall of the dam 1. A protective component 4 is installed on the surface of the water storage tank 2. The protective component 4 includes a protective plate 41. The upper and lower ends of the protective plate 41 are attached to the top horizontal plane and the lower vertical plane of the dam 1, respectively, and the central area of ​​the protective plate 41 is attached to the inclined surface of the water storage tank 2. A protrusion 42 is fixedly provided at the bottom end of the protective plate 41 and inserted into the limiting groove 3. The top end of the protective plate 41 is detachably connected to the upper surface of the dam 1 by a bolt 5. The protective plate 41 has mounting holes for bolts 5 to pass through. The upper surface of the dam 1 has threaded grooves for bolts 5 to be threaded. Bolts 5 pass through the mounting holes and connect with the threaded grooves. Slide rails 43 are symmetrically fixed on the surface of the protective plate 41. Slide plates 44 are slidably connected to the surfaces of the two slide rails 43. An arc-shaped buffer plate 45 is fixedly connected to the top of the slide plate 44. A groove is provided at the bottom of the slide plate 44. A buoyancy plate 46 is fixedly connected inside the groove. A water pipe connected to a water pump is provided in the water storage tank 2, so that the liquid inside the water storage tank 2 can be pumped out by the water pump.

[0027] Specifically, when water seeps into the dam 1, it enters the reservoir 2 and is stored, thereby reducing the permeability of the water. When water waves crash, the protective plate 41 laid on the outside of the reservoir 2 can intercept the water waves, thus protecting the reservoir 2. When the water waves act on the protective plate 41, they will act on the surface of the buffer plate 45, thereby pushing the sliding plate 44 to slide upward. The weight of the sliding plate 44 offsets the impact force of the water waves, thereby reducing the impact force of the water waves on the reservoir 2. Furthermore, the buoyancy applied to the sliding plate 44 by the buoyancy plate 46 ensures that the sliding plate 44 and the buffer plate 45 above it always float on the water surface to intercept the water waves, achieving the effect of automatically adjusting the height according to the river liquid. This is suitable for use on dams 1 with long slopes and rivers with large water level changes.

[0028] The protective plate 41 includes a lower plate 411, the top of the lower plate 411 is rotatably connected to a rotating plate 412 via a shaft, and the top of the rotating plate 412 is fixedly connected to an upper plate 413.

[0029] Specifically, when installing the protective plate 41, the protrusion 42 is inserted into the limiting groove 3 to snap the lower plate 411 in place. Then, the upper plate 413 is connected to the dam 1 by bolt 5, so that the rotating plate 412 is fixed on the outside of the water storage tank 2 for protection. By removing bolt 5, the protective plate 41 can be replaced, which facilitates the later maintenance and replacement. The bottom end of the protective plate 41 is limited by the protrusion 42 and the limiting groove 3, so that the construction personnel can disassemble and install it on the dam without going into the water to replace it.

[0030] Two slide rails 43 are slidably connected to a buffer block 47. The upper surface of the slide rail 43 is provided with a threaded hole, and a bolt 6 is threadedly connected to the threaded hole. The buffer block 47 includes a housing 471. The housing 471 has a cavity inside. A buffer airbag 477 is fixedly connected to the inner wall of the cavity. An I-shaped extrusion plate 472 is provided through the lower side of the housing 471. The surfaces of bolts 5 and 6 are plated with an anti-rust layer, which can play a certain role in preventing rust. The anti-rust layer adopts measures such as nickel plating, zinc plating or blackening treatment.

[0031] Specifically, the buffer block 47 and the sliding plate 44 are limited by bolt 2 6 to prevent them from falling off the slide rail 43. Bolt 2 6 can be removed to replace them. When the sliding plate 44 is impacted by the water wave and slides upward, its top will generate an upward thrust on the extrusion plate 472. When the extrusion plate 472 slides upward until the housing 471 abuts against bolt 2 6, the extrusion plate 472 extrudes the buffer airbag 477. The deformation of the buffer airbag 477 absorbs the impact force of the water wave, thereby further reducing the impact force when the water wave hits. This method is suitable for use on dams 1 with short slopes.

[0032] The upper surface of the slide rail 43 is provided with several slots 7, and the two sides of the housing 471 are respectively provided with slots 473. The inner top wall of the slot 473 is fixedly connected to a compression airbag 474. The compression airbag 474 and the buffer airbag 477 are connected through an air guide tube 8. The bottom of the compression airbag 474 is fixedly connected to a sliding plate 475. The outer wall of the sliding plate 475 is slidably connected to the inner wall of the slot 473. The lower surface of the sliding plate 475 is fixedly connected to a locking block 476, which is triangular in shape.

[0033] Specifically, when the impact force of the water waves is large, the large impact force of the water waves causes the sliding plate 44 to push the extrusion plate 472 upward instantly, directly squeezing the buffer airbag 477. The gas inside the buffer airbag 477 enters the extrusion airbag 474 through the air guide pipe 8, causing it to expand. The expansion of the extrusion airbag 474 pushes the sliding plate 475 and the locking plate downward, causing the locking block 476 to insert into the locking groove 7, temporarily fixing the housing 471. This allows the extrusion plate 472 to better squeeze the buffer airbag 477 for buffering under the continuous push of the water waves on the sliding plate 44. Thus, even when the sliding plate 44 is in a lower position due to the influence of the liquid surface and the impact force of the water waves cannot push the housing 471 against the bolt 6, the buffer block 47 can still provide buffering. This is suitable for use on long-slope dams 1.

[0034] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0035] Working principle: When installing the protective plate 41, the protrusion 42 is inserted into the limiting groove 3 to snap the lower plate 411 in place. Then, the upper plate 413 is connected to the dam 1 by bolt 5, so that the rotating plate 412 is fixed on the outside of the water storage tank 2 for protection. By removing bolt 5, the protective plate 41 can be replaced, which facilitates the later maintenance and replacement. The bottom end of the protective plate 41 is limited by the protrusion 42 and the limiting groove 3, so that the construction personnel can disassemble and install it on the dam without going into the water to replace it.

[0036] When water waves crash, the protective plate 41 laid on the outside of the water storage tank 2 can intercept the water waves, thus protecting the water storage tank 2. When the water waves act on the protective plate 41, they will act on the surface of the buffer plate 45, thereby pushing the sliding plate 44 to slide upward. The weight of the sliding plate 44 offsets the impact force of the water waves, thereby reducing the impact force of the water waves on the water storage tank 2. Furthermore, the buoyancy applied to the sliding plate 44 by the buoyancy plate 46 ensures that the sliding plate 44 and the buffer plate 45 above it always float on the water surface to intercept the water waves, achieving the effect of automatically adjusting the height according to the river liquid. This is suitable for use on dams 1 with long slopes.

[0037] Bolt 26 limits the buffer block 47 and sliding plate 44 to prevent them from falling off the slide rail 43. Bolt 26 can be removed to replace them. When the sliding plate 44 is impacted by water waves and slides upward, its top will generate an upward thrust on the extrusion plate 472. When the extrusion plate 472 slides upward until the housing 471 abuts against bolt 26, the extrusion plate 472 extrudes the buffer airbag 477. The deformation of the buffer airbag 477 absorbs the impact force of the water waves, thereby further reducing the impact force when the water waves hit. It is suitable for use on dams 1 with short slopes.
