Description

Technical Field

[0001] This utility model relates to the field of hydraulic dam technology, and in particular to a sealing device for the surface of a hydraulic dam. Background Technology

[0002] Existing hydraulic dam structures consist of multiple hydraulic dam bodies, which together form a dam surface to block water flow. However, gaps between adjacent hydraulic dam bodies can easily lead to water seepage, thus affecting the effectiveness of the hydraulic dam. The sealing structures of existing hydraulic dams are mostly relatively complex and require external power sources such as motors for control. In the long term, this not only makes maintenance inconvenient but also generates a large amount of energy consumption, making them unsuitable for use. Utility Model Content

[0003] Addressing the technical problem of complex structures in existing hydraulic dam surface sealing devices, this invention proposes a sealing device for hydraulic dam surfaces.

[0004] This utility model proposes a sealing device for the surface of a hydraulic dam, comprising a hydraulic dam body, with sealing mechanisms installed on both sides of the hydraulic dam body. Each sealing mechanism includes a sealing strip. Grooves are formed on both sides of the hydraulic dam body, and a main air column is fixedly connected to the inner wall of the groove. The outer surface of the main air column is fixedly connected to the outer surface of the sealing strip. The sealing strips on the opposite sidewalls of two adjacent hydraulic dam bodies can be installed in a staggered manner, thereby facilitating the staggered distribution of adjacent sealing conditions and thus facilitating sealing.

[0005] Preferably, the surface of the hydraulic dam body is provided with a sliding groove, and a shallow water airbag is fixedly connected to the inner wall of the sliding groove. Multiple shallow water airbags are arranged in an array on the inner wall of the lower end of the sliding groove.

[0006] The above technical solution utilizes shallow water airbags distributed only at the lower end of the chute, which facilitates the squeezing block to squeeze the shallow water airbags only when the water level is shallow.

[0007] Preferably, the lower inner wall of the main air column is fixedly connected to a branch air column, and the interior of the multiple branch air columns is connected to the interior of multiple shallow water airbags through an air tube.

[0008] The above technical solution utilizes multiple air columns that are distributed only inside the main air column and correspond one-to-one with multiple shallow water airbags, which are connected to each other, thus facilitating the inflation of the air columns by squeezing the shallow water airbags.

[0009] Preferably, a deep-water airbag is fixedly connected to the upper inner wall of the chute, and the interior of the deep-water airbag is connected to the interior of the main air column through an air pipe.

[0010] The above technical solution utilizes the fact that the deep-water airbag is larger than the shallow-water airbag, which makes it easier to inflate the main air column by squeezing the deep-water airbag. The deep-water airbag, shallow-water airbag and main air column can be made of elastic rubber and coated with a wear-resistant and aging-resistant coating on the outer surface.

[0011] Preferably, the inner wall of the chute is slidably connected to an extrusion block, and the surface of the extrusion block is fixedly connected to a buoyancy box via a connecting block. The buoyancy box is a lightweight hollow sealed structure.

[0012] The above technical solution utilizes the buoyancy of the buoyancy box to make it float, which facilitates the movement of the compression block. Furthermore, multiple buoyancy box-like structures can be added to the surface of the buoyancy box to increase its buoyancy at the same water level.

[0013] Preferably, a scraper is fixedly connected to the outer surface of the buoyancy box, the scraper is located between the buoyancy box and the hydraulic dam body, and the surface edges of the scraper are in contact with the surface of the hydraulic dam body.

[0014] The above technical solution utilizes a scraper to scrape the surface of the hydraulic dam as the buoyancy box moves, thereby facilitating the cleaning of algae and other impurities on the surface of the hydraulic dam.

[0015] The beneficial effects of this utility model are as follows: By installing a sealing mechanism on the side wall surface of the hydraulic dam, the sealing mechanism uses the interlocking compression between the sealing strips to achieve a seal. At the same time, the expansion of the main air column and the support air column provides power for the compression of the sealing strips. The buoyancy generated by the water level drives the compression block, which in turn compresses the shallow water air bladder and the deep water air bladder to inflate the main air column and the support air column, thus facilitating the automatic sealing of the sealing strips according to the water level.

[0018] 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.

[0019] Reference Figures 1-4 A sealing device for the surface of a hydraulic dam includes a hydraulic dam body 1. Sealing mechanisms are installed on both sides of the hydraulic dam body 1. The sealing mechanisms include sealing strips 2. Grooves are formed on both sides of the hydraulic dam body 1. A main air column 21 is fixedly connected to the inner wall of the groove. The outer surface of the main air column 21 is fixedly connected to the outer surface of the sealing strip 2. The sealing strips 2 on the opposite side walls of two adjacent hydraulic dam bodies 1 can be installed in a staggered manner, so as to facilitate the staggered distribution of adjacent sealing strips 2 and thus facilitate sealing.

[0020] To push the sealing strip 2, a groove 11 is provided on the surface of the hydraulic dam body 1. A shallow water airbag 22 is fixedly connected to the inner wall of the groove 11. Multiple shallow water airbags 22 are arranged in an array on the lower inner wall of the groove 11. By utilizing the fact that the shallow water airbags 22 are only distributed at the lower end of the groove 11, it is convenient for the extrusion block 25 to extrude the shallow water airbags 22 only when the water level is shallow. A support air column 23 is fixedly connected to the lower inner wall of the main air column 21. The interior of multiple support air columns 23 is connected to the interior of multiple shallow water airbags 22 through air pipes. The multiple support air columns 23 are also only distributed on the main air column. The main air column 21 is connected to multiple shallow water airbags 22, which correspond to each other and are connected to each other, so as to facilitate the inflation of the air column 23 by squeezing the shallow water airbags 22. The upper inner wall of the slide groove 11 is fixedly connected to a deep water airbag 24. The interior of the deep water airbag 24 is connected to the interior of the main air column 21 through an air tube. The deep water airbag 24 is larger than the shallow water airbag 22, so as to facilitate the inflation of the main air column 21 by squeezing the deep water airbag 24. The deep water airbag 24, shallow water airbag 22 and main air column 21 can be made of elastic rubber and coated with a wear-resistant and aging-resistant coating on the outer surface.

[0021] In order to compress the deep-water airbag 24 and the shallow-water airbag 22, a compression block 25 is slidably connected to the inner wall of the chute 11. A buoyancy box 26 is fixedly connected to the surface of the compression block 25 through a connecting block. The buoyancy box 26 is a lightweight hollow sealed structure. The buoyancy box 26 floats under the action of buoyancy, which makes it easy for the buoyancy box 26 to drive the compression block 25 to move. Multiple structures similar to the buoyancy box 26 can also be added to the surface of the buoyancy box 26 to increase the buoyancy of the buoyancy box 26 at the same water level.

[0022] By installing a sealing mechanism on the side wall surface of the hydraulic dam body 1, the sealing mechanism uses the interlocking compression of the sealing strips 2 to achieve sealing. At the same time, the expansion of the main air column 21 and the support air column 23 provides power for the compression of the sealing strips 2. The buoyancy generated by the water level drives the compression block 25, which in turn compresses the shallow water air bladder 22 and the deep water air bladder 24 to inflate the main air column 21 and the support air column 23, thereby facilitating the automatic sealing of the sealing strips 2 according to the water level.

[0023] A scraper 3 is fixedly connected to the outer surface of the buoyancy box 26. The scraper 3 is located between the buoyancy box 26 and the hydraulic dam body 1. The surface edges of the scraper 3 are in contact with the surface of the hydraulic dam body 1. The scraper 3 scrapes the surface of the hydraulic dam body 1 as the buoyancy box 26 moves, thereby facilitating the cleaning of algae and other impurities on the surface of the hydraulic dam body 1.

[0024] Working principle: When in use, the buoyancy box 26 drives the compression block 25 to slide down to the lowest point in the slide groove 11 under the action of gravity. The main air column 21 is not filled with air, and the gap between the adjacent sealing strips 2 is relatively large.

[0025] When the water level is shallow, the buoyancy box 26 drives the extrusion block 25 to rise in the slide 11. The extrusion block 25 extrudes the shallow water airbag 22 at the lower end of the slide 11. The air in the shallow water airbag 22 fills the support column 23. The support column 23 expands and pushes the lower end of the main air column 21, filling and blocking the lower gap between adjacent sealing strips 2, thus sealing the lower end between adjacent sealing strips 2.

[0026] After the water level rises, the buoyancy box 26 drives the extrusion block 25 to continue rising in the chute 11. The extrusion block 25 slides over the surface of the shallow water airbag 22 and extrudes upwards to the deep water airbag 24. After being extruded, the deep water airbag 24 inflates into the main air column 21. The main air column 21 inflates and expands, filling and blocking the gaps between the sealing strips 2, thus sealing the adjacent hydraulic dam bodies 1.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
