Description

Technical Field

[0001] This invention relates to the field of underwater antifouling technology, and in particular to an improved underwater antifouling and anti-fouling component. Background Technology

[0002] Water enclosures are primarily used in lake pollution control, water body restoration, aquatic ecosystem reconstruction, silt dredging, reclamation operations, and water diversion and algae control in scientific research and water engineering. They prevent the spread, drift, and diffusion of harmful substances, achieving the goals of water body restoration and water quality improvement. Especially during port construction and dredging operations, the spread of turbid mudflows can harm the ecological environment and aquaculture. Water enclosures isolate local construction areas from non-operational areas, preventing pollution from spreading and effectively protecting the ecological environment and aquaculture areas.

[0003] Existing, commercially available underwater antifouling and barrier components have poor adjustability. Under the action of external loads such as water flow, the curtain is prone to deformation due to the lack of resistance to erosion. Furthermore, when the water flow velocity is high, it will reduce the interception area and effective interception depth of the curtain, thus affecting its antifouling effect. At the same time, suspended matter in the water will gradually adhere to the curtain during the continuous blocking process, which will not only increase the load on the curtain, but also improve the corrosion of the curtain, seriously affecting the service life of the antifouling and barrier components.

[0004] Based on the above-mentioned technical problems, we propose an improved water system pollution prevention and isolation device. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by proposing an improved underwater antifouling and anti-fouling component.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An improved underwater antifouling and barrier component includes a float with a cable threaded through its bottom. The cable has loops at both ends, and an antifouling curtain is located at the bottom of the cable. The antifouling curtain is composed of several 4.0m x 3.0m block-shaped antifouling and barrier components connected in series. Each antifouling and barrier component includes a frame and tensile strength bands. Adjacent tensile strength bands are fixedly connected to the frame via reinforcing ropes. The tensile strength bands are vertically connected to the frame via a drainage mechanism. The drainage mechanism performs drainage operations by extending and retracting the tensile strength bands under the impact of water flow.

[0008] The float is composed of multiple hollow buoys spaced apart, and the surface of the float is covered with UV-resistant fabric, with several reflective strips attached to the surface of the UV-resistant fabric.

[0009] The anti-fouling and anti-fouling component is made of anti-fouling material, with a lighter top and heavier bottom, which allows the anti-fouling curtain to hang down in the water.

[0010] The tensile strength belt includes a telescopic belt and a water guide pipe. The telescopic belt undergoes a certain stretching operation as the water flow impacts, which can achieve the function of resisting the erosion of the flow velocity.

[0011] The water guide pipe performs water pumping on the clean water side and drainage on the sewage side during the stretching process of the telescopic belt through the pumping and drainage mechanism, thereby cleaning the suspended matter on the telescopic belt and reducing the overall load of the anti-fouling curtain.

[0012] Optionally, a buckle is provided on one side of the frame, and a retaining ring is provided on the other side of the frame, with adjacent frames connected in series by the buckle and the retaining ring.

[0013] Optionally, the pumping and draining mechanism includes a piston plate and a cylinder, the cylinder being disposed in the horizontal direction of the frame, and the piston plate being slidably connected to the cylinder via a spring assembly.

[0014] Optionally, one end of the water guide pipe is movably connected to the frame via a tension spring, and the other end of the water guide pipe is fixedly connected to the piston plate.

[0015] Optionally, one side of the telescopic belt is provided with multiple sets of dirt-separating plates. The dirt-separating plates move as the telescopic belt is stretched, swinging and cleaning the suspended matter attached to the telescopic belt.

[0016] Optionally, the water guide pipe is provided with an inlet near the clean water side and a drain outlet near the sewage side, and the inlet and drain outlet are connected to the cylinder body through a valve block;

[0017] The drain outlets are inclinedly arranged on the upper and lower sides of the baffle plate to achieve water spraying and rinsing of suspended matter on the baffle plate.

[0018] Optionally, both the inlet and outlet are provided with flared valve ports, and the valve block is movably connected to the valve ports via a return spring. The valve ports on the same group of inlets and outlets have the same direction.

[0019] The telescopic belt stretches instantly upon impact with water flow, causing the water guide pipe to slide along the piston plate and cylinder. At this time, the inside of the cylinder is under negative pressure, and the water guide pipe draws water through the inlet. When the impact of the water flow on the telescopic belt weakens, the piston plate returns to its original position under the action of the spring assembly. At this time, the inside of the cylinder is under high pressure, and the water guide pipe sprays water through the drain to flush the suspended matter on the dirt-separating plate.

[0020] The present invention has the following advantages:

[0021] This invention features good safety, warning function, and simple implementation. It can isolate pollutants in water bodies in all directions and according to the degree of pollution. It also has the function of resisting the scouring of water flow. It can effectively solve the problem that underwater anti-fouling and anti-fouling components are prone to deformation under the action of water flow and other external loads. Furthermore, it can automatically clean suspended solids in the water during the scouring process, avoiding excessive load, dirt accumulation and corrosion of the curtain during continuous blocking. It has good application prospects.

[0022] This invention employs a stretchable, high-strength belt. When the anti-fouling curtain is impacted by water flow, each anti-fouling and dirt-isolating component is stretched and eroded by the high-strength belt, preventing deformation and damage to the curtain. Simultaneously, during the stretching process of the high-strength belt upon impact with water flow, the water guide pipe pumps water through a drainage mechanism, achieving clean water pumping and wastewater drainage. This cleans suspended matter adhering to the anti-fouling curtain, reduces the overall load on the curtain, prevents dirt from adhering to it, and extends the curtain's service life.

[0023] The outstanding feature of this invention is that it utilizes the scouring effect of external loads such as water flow on the antifouling curtain. This solves the problem of damage caused by deformation due to water flow impact in traditional antifouling curtains. At the same time, it uses water pumping to remove clean water from one side of the antifouling curtain and clean the surface of the sewage side, turning "harm" into "benefit" and achieving a long-lasting antifouling effect for the underwater antifouling and anti-fouling component.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-5 An improved underwater antifouling and anti-fouling component 4 includes a float 1, with a cable 2 threaded through the bottom of the float 1. The cable 2 has loops at both ends. It should be noted that the float 1 is composed of multiple hollow buoys spaced apart. The surface of the float 1 is covered with UV-resistant cloth for protection under long-term sunlight. Several reflective strips are attached to the surface of the UV-resistant cloth to facilitate warning when the vessel is in the water. The end of the cable 2 is used with a counterweight to fix the entire device for antifouling and anti-fouling operations.

[0032] Reference Figure 1 and Figure 2 The bottom of the cable 2 is equipped with a dirt-proof curtain 3, which is composed of several 4.0m*3.0m block-shaped dirt-proof and dirt-blocking components 4 connected in series. It should be noted that there is a buckle 51 on one side of the frame 5 and a retaining ring 52 on the other side of the frame 5. Adjacent frames 5 are connected in series by buckles 51 and retaining rings 52. The dirt-proof and dirt-blocking components 4 are made of dirt-blocking material, which is light at the top and heavy at the bottom, so that the entire dirt-proof curtain 3 hangs down in the water, which improves the overall dirt-proof and dirt-blocking effect while making the device easy to assemble.

[0033] Reference Figure 2 and Figure 3 The anti-fouling and anti-fouling component 4 includes a frame 5 and a tensile strength band 6. The tensile strength band 6 is set vertically, and adjacent tensile strength bands 6 are fixedly connected to the frame 5 by reinforcing ropes 7. The tensile strength band 6 includes a telescopic band 61 and a water guide pipe 62. The telescopic band 61 is stretched to a certain extent as the water flow impacts, which can achieve the function of resisting the scouring of the flow velocity.

[0034] The tensile strength band 6 is vertically connected to the frame 5 via a drainage mechanism 8. The drainage mechanism 8 performs drainage operations by extending and retracting the tensile strength band 6 under the impact of water flow. Specifically, the drainage mechanism 8 includes a piston plate 81 and a cylinder 82. The cylinder 82 is located in the horizontal direction of the frame 5. The piston plate 81 is slidably connected to the cylinder 82 via a spring assembly 83. One end of the water guide pipe 62 is movably connected to the frame 5 via a tension spring 621, and the other end of the water guide pipe 62 is fixedly connected to the piston plate 81, so that when the extension band 61 is stretched under the impact of water flow, it can drive the piston plate 81 to move.

[0035] More specifically, one side of the telescopic belt 61 is provided with multiple sets of dirt-separating plates 611. The dirt-separating plates 611 can block and concentrate suspended matter on the telescopic belt 61 to a certain extent. When the telescopic belt 61 is stretched by the impact of water flow, the dirt-separating plates 611 will produce a "tilting-horizontal-tilting" action process, and then clean the suspended matter attached to the telescopic belt 61 through a certain swing, so as to prevent dirt from adhering to the surface of the dirt-separating curtain 3.

[0036] Reference Figure 3-5 The water guide pipe 62, through the pumping and draining mechanism 8, performs water pumping on the clean water side and draining on the sewage side during the stretching process of the telescopic belt 61, thereby cleaning suspended matter on the telescopic belt 61 and reducing the overall load on the anti-fouling curtain 3. It should be noted that the water guide pipe 62 has an inlet 622 near the clean water side and a drain outlet 623 near the sewage side. Both the inlet 622 and the drain outlet 623 are connected to the cylinder 82 via the valve block 9.

[0037] Furthermore, the drain outlet 623 is inclinedly arranged on the upper and lower sides of the baffle plate 611, and works with the pumping and draining mechanism 8 to spray water to wash the suspended matter on the baffle plate 611. Both the inlet 622 and the drain outlet 623 are equipped with a trumpet-shaped valve port 624. The valve block 9 is movably connected to the valve port 624 through the return spring 91. The valve ports 624 on the same set of inlet 622 and drain outlet 623 are in the same direction, so that the water guide pipe 62 can only pump water on the clean water side, avoiding the blockage of the inlet 622 by suspended matter in the sewage. Water is sprayed through the drain outlet 623 to clean the dirt attached to the baffle plate 611 and the telescopic belt 61.

[0038] Furthermore, the telescopic belt 61 stretches instantly upon impact with the water flow, causing the water guide pipe 62 to slide along the piston plate 81 and the cylinder 82. At this time, the inside of the cylinder 82 is under negative pressure, and the water guide pipe 62 draws water through the inlet 622. When the impact of the water flow on the telescopic belt 61 weakens, the piston plate 81 returns to its original position under the action of the spring assembly 83. At this time, the inside of the cylinder 82 is under high pressure, and the water guide pipe 62 sprays water to wash the suspended matter on the dirt separator 611 through the drain outlet 623.

[0039] The operating principle of the present invention is described as follows:

[0040] When the device is in use, the operator connects the anti-fouling and anti-contamination components 4 in series below the float 1 using buckles 51 and rings 52, and places it in the designated water area to create a water barrier. When the anti-fouling curtain 3 is impacted by water flow, each anti-fouling and anti-contamination component 4 is stretched and eroded by the tensile strength belt 6 to prevent deformation and damage to the curtain. When the telescopic belt 61 in the tensile strength belt 6 is stretched at the moment of impact by water flow, the water guide pipe 62 drives the piston plate 81 and cylinder 82 to slide. At this time, the inside of the cylinder 82 is under negative pressure. The valve block 9 at the end of the water guide pipe 62 near the inlet 622 opens, and the valve block 9 at the end of the water guide pipe 62 near the outlet 623 closes, allowing the water guide pipe 62 to pump water through the inlet 622. When the water flow impact on the telescopic belt 61 weakens, the force of the spring assembly 83 is greater than the force of the water flow on the telescopic belt 61. The external load force causes the piston plate 81 to reset in the cylinder 82. At this time, the inside of the cylinder 82 is under high pressure. The valve block 9 at the end of the water guide pipe 62 near the water inlet 622 is closed, and the valve block 9 at the end of the water guide pipe 62 near the drain outlet 623 is opened. The water guide pipe 62 sprays water to wash the suspended matter on the dirt separator 611 through the drain outlet 623, so as to prevent the suspended matter in the water from adhering to the curtain during the blocking process, reduce the load on the curtain and the corrosion, and improve the service life of the curtain.

[0041] The above description is only a preferred embodiment of the present invention. It is impossible to exhaustively describe all embodiments here. However, the protection scope of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the protection scope of the present invention.
