Description

Technical Field

[0001] This utility model relates to the field of dam construction technology, and in particular to a barrier dam with drainage function for use in dams. Background Technology

[0002] During the construction and utilization of the Yudi Dam, the salinization of the dam site has been a pressing problem that needs to be solved. As an important water conservancy project, the Yudi Dam's main functions are water storage and drainage to regulate water flow, prevent floods, and provide irrigation water for surrounding farmland. However, over long-term use, the accumulation of salts carried by the water flow on the rear side of the dam site has led to increasingly severe soil salinization.

[0003] Salinization not only reduces soil fertility, affecting crop growth and yield, but also poses a potential threat to dam structure. The accumulation of salt increases soil osmotic pressure, making it difficult to retain soil moisture, thus impacting the stability and safety of the dam.

[0004] Therefore, designing a barrier dam with drainage function for local dams, and using efficient drainage and salt barrier technology to effectively improve the salinization of the dam site and make rational use of the dam site, has important practical significance and application value. Utility Model Content

[0005] The barrier dam of this invention has a compact structure and is easy to operate. It is suitable for ground dam scenarios of various sizes. It not only improves the drainage efficiency and structural stability of ground dams, but also reduces maintenance costs. It has significant technological progress and practical application value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A barrier dam with drainage function for ground dams includes a dam frame, a lifting mechanism is fixedly installed on the upper surface of the dam frame, and a barrier dam body is installed on the inner side of the dam frame, with drainage components installed on the surface of the barrier dam body. The drainage assembly includes a barrier mesh plate fixedly installed on the water-facing side of the barrier dam body. The barrier mesh plate is used to block and filter salt in the water. The barrier dam body has a drainage cavity inside and several drainage holes on the water-facing side. A drainage pipe is fixedly embedded on the back of the barrier dam body. The inlet end of the drainage pipe extends into the drainage cavity. A drainage pump is installed on the top of the dam body frame. A corrugated connecting pipe is fixedly connected to the input end of the drainage pump. The end of the corrugated connecting pipe away from the drainage pump is fixedly connected to the drainage end of the drainage pipe.

[0007] In a preferred embodiment, the lifting mechanism includes a protective cover fixedly connected to the top of the dam frame. A drive motor is fixedly installed on the inner wall of the protective cover. A drive shaft is fixedly connected to the output shaft of the drive motor. Two worm gears are fixedly arranged on the surface of the drive shaft, and the thread directions of the two worm gears are opposite to each other.

[0008] In a preferred embodiment, two rotating rods are rotatably connected between the front and rear inner walls of the protective cover. A winding wheel is fixedly mounted on the surface of the rotating rod, and a suspension rope is wound around the surface of the winding wheel. The end of the suspension rope away from the winding wheel extends downward into the interior of the dam frame. Two lifting rings are symmetrically arranged on the upper surface of the barrier dam, and the bottom end of the suspension rope is fixedly connected to the surface of the lifting ring.

[0009] In a preferred embodiment, a worm gear is fixedly connected to the surface of the rotating rod, the position of the worm gear corresponds to the worm, the two worms mesh with the two worm gears respectively, and two rope through holes are opened on the upper surface of the dam frame, the position of the rope through holes corresponds to the rope, and the rope passes through the inside of the rope through holes.

[0010] In a preferred embodiment, a filter screen is fixedly installed on the inner wall of the drainage cavity, and the position of the filter screen corresponds to the water inlet of the drainage pipe.

[0011] In a preferred embodiment, the inner wall of the drainage cavity is fixedly connected with several reinforcing baffles, and the bottom of the reinforcing baffles is provided with water guiding holes.

[0012] In a preferred embodiment, a water delivery pipe is fixedly installed at the output end of the drainage pump, and the end of the water delivery pipe away from the drainage pipe extends to an external drainage channel.

[0013] In a preferred embodiment, two limiting guide rods are fixedly installed on the inner top wall of the dam frame, and two limiting sleeves are fixedly connected to the back of the barrier dam. The positions of the limiting sleeves correspond to the limiting guide rods, and the limiting sleeves are slidably connected to the surfaces of the limiting guide rods.

[0014] As can be seen from the above, the barrier dam with drainage function provided by this utility model has the following technical effects.

[0015] Firstly, the dam features efficient drainage and salt barrier. By installing a barrier mesh panel on the water-facing side, salt in the water is effectively blocked and filtered, preventing salt accumulation on the rear side of the dam and thus avoiding damage to the dam structure and the surrounding environment. The drainage cavities inside the dam and the drainage holes on the water-facing side, combined with the drainage pipes at the rear and the drainage pump at the top, achieve highly efficient water flow guidance and drainage, significantly improving the drainage efficiency of the dam.

[0016] Secondly, the dam features flexible lifting and lowering adjustment. The lifting mechanism uses a drive motor to power a worm gear and worm wheel, which in turn drives a winding wheel to raise and lower the hoisting rope, enabling flexible adjustment of the dam's height. This design not only facilitates adjusting the dam's height under different water levels but also enhances the structure's stability and durability. The meshing transmission of the worm gear and worm wheel has a self-locking function, ensuring that the dam maintains a fixed height without external force, preventing accidental raising or lowering due to water flow impact.

[0017] Thirdly, the structure is robust and easy to maintain. The filter screen and reinforced baffles installed on the inner wall of the drainage cavity not only further enhance the structural strength of the dam but also effectively prevent debris from entering the drainage system, reducing maintenance frequency. The water guide holes on the reinforced baffles ensure unobstructed water flow while preventing damage to the dam from excessive local pressure. The design of the limit guide rod and limit sleeve restricts the movement range of the dam body, improving stability and safety during lifting and lowering. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1 to 5 A type of retaining dam with drainage function mainly includes a dam frame 1, a lifting mechanism 2, a retaining dam body 3, drainage components 4, and other auxiliary structures. These components work together to achieve functions such as efficient drainage, salt barrier, and flexible lifting adjustment.

[0026] The dam frame 1 is the supporting structure of the entire barrier dam. It is designed to be robust and stable, capable of withstanding the impact of water flow and the weight of the dam itself. The dam frame 1 is made of high-strength materials, such as steel or concrete, to ensure its long-term durability.

[0027] A lifting mechanism 2 is fixedly installed on the upper surface of the dam frame 1. This mechanism is used to adjust the height of the barrier dam 3 to adapt to different water level conditions. In addition, a barrier dam 3 is installed on the inner side of the dam frame 1. The barrier dam 3 is a key component for realizing the functions of drainage and salt barrier.

[0028] It is worth noting that the lifting mechanism 2 is designed to allow for flexible adjustment of the height of the barrier dam 3. Specifically, the lifting mechanism 2 includes components such as a protective cover 201, a drive motor 202, a drive shaft 203, a worm gear 204, a rotating rod 205, a winding reel 206, a hoisting rope 207, a hoisting ring 208, and a worm wheel 209.

[0029] The protective cover 201 is fixedly connected to the top of the dam frame 1 to protect the internal drive motor 202 and other transmission components from interference and damage from the external environment.

[0030] It should be noted that the drive motor 202 is installed on the inner wall of the protective cover 201 and serves as the power source for the lifting mechanism 2. The output shaft of the drive motor 202 is fixedly connected to the drive shaft rod 203. When the drive motor 202 starts, it will drive the drive shaft rod 203 to rotate together.

[0031] Two worm gears 204 are fixedly mounted on the surface of the drive shaft 203, and the thread directions of the two worm gears 204 are opposite to each other. This design causes the two worm gears 204 to rotate in opposite directions when the drive shaft 203 rotates, thereby driving the two worm wheels 209 (and the rotating rods 205 connected to them) to rotate in opposite directions.

[0032] It should be noted that the rotating rod 205 is rotatably connected between the front and rear inner walls of the protective cover 201, and a winding wheel 206 is fixedly installed on its surface. The winding wheel 206 is used to wind the hoisting rope 207. When the rotating rod 205 rotates, the winding wheel 206 will rotate accordingly, thereby winding and unwinding the hoisting rope 207.

[0033] One end of the hoisting rope 207 is wound around the winding reel 206, and the other end extends downward into the interior of the dam frame 1, where it is fixedly connected to the lifting ring 208 on the upper surface of the barrier dam 3. When the winding reel 206 winds up or down the hoisting rope 207, it will cause the barrier dam 3 to move up and down, thereby adjusting its height.

[0034] It should be noted that the lifting rings 208 are symmetrically arranged on the upper surface of the barrier dam body 3 for connection with the lifting ropes 207. The design of the lifting rings 208 ensures that the lifting ropes 207 can be firmly fixed to the barrier dam body 3, preventing them from falling off during lifting.

[0035] It should be noted that the worm gear 209 is fixedly connected to the surface of the rotating rod 205, corresponding to the position of the worm 204. The two worms 204 mesh with the two worm gears 209 respectively. When the worm 204 rotates, it drives the worm gears 209 (and the rotating rod 205 connected to them) to rotate. The meshing transmission between the worm 204 and the worm gears 209 has a self-locking function, enabling it to maintain a fixed position without external force, ensuring the stability of the retaining dam 3.

[0036] In addition, two rope-penetrating holes are provided on the upper surface of the dam frame 1. The positions of the rope-penetrating holes correspond to the positions of the ropes 207, and the ropes 207 pass through the inside of the rope-penetrating holes. This design allows the ropes 207 to be raised and lowered freely without affecting the structural stability of the dam frame 1.

[0037] It is worth noting that the barrier dam 3 is a key component for achieving drainage and salt barrier functions. Its water-facing side is equipped with a drainage assembly 4, which contains a drainage cavity 402, and several drainage holes 403 are also present on the water-facing side. When water flows against the barrier dam 3, the water enters the drainage cavity 402 through the drainage holes 403 and is then discharged through the drainage assembly 4.

[0038] Specifically, the drainage assembly 4 includes components such as a barrier mesh plate 401, a drainage pipe 404, a drainage pump 405, and a corrugated connecting pipe 406. The barrier mesh plate 401 is fixedly installed on the water-facing side of the barrier dam 3 to block and filter salt in the water. The drainage pipe 404 is fixedly embedded on the back side of the barrier dam 3, with its inlet end extending into the drainage cavity 402. The input end of the drainage pump 405 is fixedly connected to the drainage end of the drainage pipe 404 through the corrugated connecting pipe 406, for pumping out and discharging water from inside the drainage cavity 402.

[0039] It should be noted that the material of the mesh in the barrier mesh 401 is a high-density polyethylene (HDPE) geomembrane, which can effectively prevent the migration of water and dissolved salts, thereby achieving the effect of blocking and filtering salts in the water.

[0040] To further enhance drainage efficiency and structural stability, a filter screen 407 and a reinforcing baffle 408 are fixedly installed on the inner wall of the drainage cavity 402. The filter screen 407 is located at the inlet of the drainage pipe 404 to prevent debris from entering the drainage system and causing blockage. The reinforcing baffle 408 is used to enhance the structural strength of the drainage cavity 402 and prevent damage to the dam body due to excessive local pressure. A water guide hole 409 is also provided at the bottom of the reinforcing baffle 408 to ensure unobstructed water flow.

[0041] In addition to the main components mentioned above, the barrier dam of this invention also includes other auxiliary structures to ensure its overall performance and stability, such as limiting guide rods 5 and limiting sleeves 6. Two limiting guide rods 5 are fixedly installed on the inner top wall of the dam frame 1, and two limiting sleeves 6 are fixedly connected to the back of the barrier dam body 3. The positions of the limiting sleeves 6 correspond to the limiting guide rods 5, and the limiting sleeves 6 are slidably connected to the surfaces of the limiting guide rods 5. This design limits the range of movement of the barrier dam body 3 during the lifting and lowering process, improving its stability and safety.

[0042] It should be noted that a water delivery pipe 410 is fixedly installed at the output end of the drainage pump 405, and the end of the water delivery pipe 410 away from the drainage pipe 404 extends to an external drainage channel. This design can guide the discharged water to a designated drainage area, avoiding pollution to the surrounding environment.

[0043] Working principle: When using the barrier dam of this invention, the height of the barrier dam body 3 needs to be adjusted according to the actual water level conditions. This can be achieved by starting the drive motor 202, which will drive the drive shaft 203 and worm gear 204 to rotate, thereby driving the worm wheel 209 and rotating rod 205 to rotate. The rotation of the rotating rod 205 will drive the winding wheel 206 to wind up and unwind the hoisting rope 207, thereby adjusting the height of the barrier dam body 3.

[0044] Once the height of the retaining dam 3 is adjusted, the water flow will impact the water-facing surface of the retaining dam 3 and enter the drainage cavity 402 through the drainage hole 403. Inside the drainage cavity 402, the water will be filtered by the filter screen 407 and guided by the reinforcing baffle 408 before entering the drainage pipe 404. Then, the drainage pump 405 will pump the water out of the drainage pipe 404 through the corrugated connecting pipe 406 and discharge it to the external drainage channel through the water delivery pipe 410.

[0045] Throughout the entire operation, the barrier mesh 401 continuously blocks and filters salt in the water, preventing salt from accumulating behind the dam and causing damage to the dam structure and the surrounding environment. Simultaneously, the guide rod 5 and the limiting sleeve 6 continuously restrict the movement range of the barrier dam 3, ensuring its stability and safety.

[0046] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
