Description

Technical Field

[0001] The utility model relates to the field of environmental pollution control equipment, in particular to an anti-pollution curtain structure which is easy to fix. Background Art

[0002] Anti-pollution curtains have a wide range of applications in the field of water pollution control. They are often used to deal with sudden pollutants in water bodies and sludge pollution in water bodies caused during engineering construction. Waters protected by anti-pollution curtains can effectively block the further spread of pollutants, protect a wider range of waters, and have obvious social benefits. As a new water environment management product, anti-pollution curtains are usually composed of buoys, permeable curtains and counterweights. They can form a water curtain in the water to block pollutants such as silt and suspended matter. Water can flow freely on both sides of the anti-pollution curtain, thereby isolating the clean area from the polluted area. Chinese patent application 2023208376417 discloses "A Marine Anti-fouling Curtain", with the publication number CN219731912U, which includes a marine anti-fouling curtain body integrally formed by a single-layer aging-resistant high-strength round wire filter cloth; a floating body is provided on the upper part of the marine anti-fouling curtain body, which is formed by the top edge of the marine anti-fouling curtain body rolled inward and wrapped with buoyancy material; the main tension rope of the anti-fouling curtain is sewn on the upper part of the marine anti-fouling curtain body and below the floating body; a number of counterweights are sewn on the lower part of the marine anti-fouling curtain body; the technical solution proposed by the above-mentioned utility model is mainly to improve on the basis of the original design, so that the anti-fouling curtain is more suitable for marine engineering, and the effect is improved while optimizing and streamlining the manufacturing process. However, when the anti-fouling curtain is used in relatively wide waters such as the sea, the underwater bottom is often difficult to be stably fixed, causing the anti-fouling curtain to shift with the water flow. Utility Model Content

[0003] Therefore, in response to the above problems, the utility model proposes an anti-fouling curtain structure with a simple structure, which is not easy to move during use and is easy to fix, so as to solve the technical problem that the existing anti-fouling curtain is easily displaced by the water flow when used in wide waters.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model describes an anti-fouling curtain structure that is easy to fix, which includes a water-permeable curtain, a float connected to the upper end of the water-permeable curtain, and a counterweight sinker connected to the lower end of the water-permeable curtain. The upper end of the water-permeable curtain is provided with a first connection hole array at equal intervals, and the first connection hole array is composed of a plurality of first connection holes arranged in a row in the horizontal direction. A second connection hole is provided on the float, and a connecting ring is passed between the first connection hole and the second connection hole. The counterweight sinker includes a cylindrical counterweight chamber formed by sewing and connecting high-density wear-resistant gauze, and a counterweight material filled in the counterweight chamber. The length of the counterweight chamber is equal to the lower edge of the water-permeable curtain, and the upper side of the weight chamber is fixedly connected to the lower edge of the water-permeable curtain; a plurality of anti-displacement hooks are provided at intervals on the lower side of the counterweight chamber.

[0006] Through this solution, when the anti-fouling curtain is used in deeper and larger waters, the anti-displacement hook can reach the base in the water and be embedded in the base as it swings with the water flow, thereby preventing the water-permeable curtain from shifting with the water flow and affecting the use effect; the connecting ring between the buoy and the water-permeable curtain can flexibly adjust the number of buoys, making it easy to disassemble and replace.

[0007] Preferably, the anti-displacement hook includes a connecting rod whose upper end is fixedly connected to the counterweight chamber and a hook head arranged at the lower end of the connecting rod. The hook head is in the shape of an arrow that bends upward in an arc from the lower end of the connecting rod, and the vertical height of the hook head is one third of the height of the connecting rod.

[0008] Through this solution, the anti-displacement hook can more easily hook the underwater base.

[0009] Preferably, a hook plate is provided at the upper end of the hook head, and the hook plate is a rectangular plate-shaped structure, and one side of the hook head is fixedly welded to the side surface of the hook plate.

[0010] Through this solution, the firmness of the anti-displacement hook position can be improved, and it is not easy to get unhooked. At the same time, the hook plate can protect the hook head.

[0011] Preferably, an integrally formed wing plate is provided on the outer wall of the buoy, and the wing plate is a rectangular flat plate extending radially from the outer wall of the buoy.

[0012] Through this solution, the wing plate can increase the buoyancy of the buoy and improve the stability of the buoy.

[0013] Preferably, a rubber layer is provided on the inner walls of the first connecting hole and the second connecting hole.

[0014] Through this solution, the rubber layer can buffer the impact force between the connecting ring and the connecting hole, preventing the connecting ring from being torn off by the impact force during wave fluctuations.

[0015] Compared with the existing anti-fouling curtain, the utility model has better performance. By arranging anti-displacement hooks on the lower end edge of the counterweight sinker, it can ensure that when the anti-fouling curtain is used in deeper and larger waters, the anti-displacement hooks can reach the base in the water and be embedded in the base as the water flows, thereby preventing the water-permeable curtain from being displaced by following the water flow and affecting the use effect.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figure 1 As shown, the utility model discloses an anti-fouling curtain structure that is easy to fix, comprising a water-permeable curtain 2, a buoy 1 connected to the upper end of the water-permeable curtain 2, and a counterweight foot connected to the lower end of the water-permeable curtain 2. The water-permeable curtain 2 is made of a water-permeable high-density mesh, which has little effect on the water flow during use and is only used to block larger particles of solid and oily impurities. The buoy 1 is made of a cylindrical foam plastic or a hollow plastic barrel, and an integrally formed wing plate 11 is provided on the outer wall of the buoy 1. The wing plate 11 is a rectangular flat plate that radially extends from the outer wall of the buoy 1. The wing plates 11 on both sides of the buoy 1 help to maintain the balance of the buoy 1 and prevent the buoy 1 from rolling.

[0023] The upper end of the water-permeable curtain is provided with a first connection hole array at intervals at equal distances. The first connection hole array is composed of a plurality of first connection holes 21 arranged in a row in the horizontal direction. The float 1 is provided with a second connection hole 12, and a connection ring 5 is inserted between the first connection hole 21 and the second connection hole 12. The connection ring 5 is an open annular structure made of corrosion-resistant plastic with high strength and high elasticity. The connection ring 5 is twisted to expand the opening of the annular structure, and it can be put on the first connection hole 21 or the second connection hole 12 from the opening of the annular structure, so that the float 1 is installed on the water-permeable curtain 2. After releasing the hand, the opening of the connection ring 5 is automatically closed. The first connection hole 21 can be a through hole directly opened on the water-permeable curtain 2, or a hard plastic ring can be embedded on the inner wall of the through hole. The second connection hole 12 can be a through hole directly opened on the float 1, or a plastic circle connected to the float 1.

[0024] In addition, if Figure 4 As shown, a rubber layer 22 is disposed on the inner wall of the first connection hole 21 and the second connection hole 12. The rubber layer 22 is corrosion-resistant and has a certain toughness and elasticity, which can protect the connection holes and avoid damaging the connection ring 5.

[0025] like Figure 1 , Figure 3 As shown, the counterweight foot includes a cylindrical counterweight chamber 6 formed by sewing high-density wear-resistant gauze, and a counterweight material 32 filled in the counterweight chamber 6. The high-density wear-resistant gauze has water permeability and high wear resistance. The counterweight material 32 can be selected from solid granular materials that are insoluble in water and have a large specific gravity, such as mud or metal debris. In this embodiment, mud is used. After the counterweight material 32 is loaded into the counterweight chamber 6, the two ends of the counterweight chamber 6 can be sewn; the length of the counterweight chamber 6 is equal to the lower edge of the water-permeable curtain 2, and the upper side of the weight chamber 6 is fixedly connected to the lower edge of the water-permeable curtain 2 by sewing or silk thread binding; a plurality of anti-displacement hooks 4 are arranged at intervals on the lower side of the counterweight chamber 6.

[0026] like Figure 2 As shown, the anti-displacement hook 4 includes a connecting rod 41 whose upper end is fixedly connected to the counterweight chamber 6, and a hook head 42 arranged at the lower end of the connecting rod 41. The hook head 42 is an arrow shape that is curved upward from the lower end of the connecting rod 41, and the vertical height of the hook head 42 is one-third of the height of the connecting rod 41. The connecting rod 41 and the hook head 42 are integrally formed of cast iron or stainless steel. The upper end of the connecting rod 41 has a ring for tying or sewing it to the counterweight chamber 6. The hook head 42 of the connecting rod 41 can be bent to only one side, such as Figure 2 As shown, there may also be two hooks 42 arranged in mirror image on both sides of the connecting rod 41 .

[0027] As another embodiment of the present invention, the anti-displacement hook 4 is a J-shaped structure made of plastic and is connected to the counterweight chamber 6 by a hot melt process. The specific number of the anti-displacement hooks 4 is determined according to the actual specifications of the product.

[0028] When in use, unfold the water-permeable curtain 2, connect a certain number of buoys 1 to the first connecting hole 21 at the upper end of the water-permeable curtain 2 through the connecting ring 5, and ensure that at least one buoy 1 is provided at both sides and the middle of the water-permeable curtain 2; at the same time, load the counterweight material 32 into the counterweight chamber 6, sew up the two ends of the counterweight chamber 6, and tie a certain number of anti-displacement hooks 4 to the counterweight chamber 6, and ensure that at least one anti-displacement hook 4 is provided at both ends and the middle of the counterweight chamber 6; put the assembled water-permeable curtain 2 into the water, and due to the effect of buoyancy, the buoys 1 The upper end of the water-permeable curtain 2 is pulled and the counterweight sinking foot drags the lower end of the water-permeable curtain 2 to the bottom, so that the water-permeable curtain 2 is in an upright state in the water. After the counterweight chamber 6 sinks to the bottom, the anti-displacement hook 4 is tilted or laid flat on the bottom of the water. When the water-permeable curtain 2 is displaced under the action of the water flow, the counterweight chamber 6 will drag the connecting rod 41 to move horizontally. The horizontally moving hook head 42 can easily hook the reefs on the bottom of the water or embed into the mud on the bottom of the water, preventing the water-permeable curtain 2 from moving further, thereby preventing the water-permeable curtain from being displaced following the water flow and affecting the use effect.

[0029] As a further improvement of the present invention, a hook plate 43 is provided at the upper end of the hook head 42, and the hook plate 43 is a rectangular plate structure, and one side of the hook head 42 is fixedly welded to the side of the hook plate 43. In this way, the hook head 42 is located on one side of the hook plate 43, and at the same time, the two sides of the hook plate 43 extend to both sides respectively, forming a stable triangular support structure together, which can not only strengthen the structural strength of the hook head part, but also help the hook head 42 to hook and fit into the reef gap of the underwater base.
