Description

Technical Field

[0001] This utility model belongs to the field of anti-fouling screen technology, and relates to an anti-fouling screen, specifically a foldable plug-in type anti-fouling screen. Background Technology

[0002] The development of water engineering projects is closely related to human economic activities, including projects such as land reclamation and river dredging. However, these projects often involve the spread of sediment, pollutants, and other substances, posing a potential pollution risk to the surrounding aquatic environment. Therefore, preventing such spread has become an important issue in the implementation of water engineering projects.

[0003] Traditionally, fixed anti-fouling screens are commonly used in water engineering projects such as land reclamation and river dredging to prevent the spread of silt and pollutants. However, traditional anti-fouling screens face a series of challenges in practical applications. First, their fixed design makes them inflexible in responding to changes in the construction site, thus failing to meet the needs of different project areas. Second, traditional anti-fouling screens are prone to clogging and damage from debris, reducing their anti-fouling effect and even increasing subsequent cleaning costs. To overcome the problems of traditional anti-fouling screens, researchers have proposed a new type of anti-fouling screen design in recent years, such as a portable anti-fouling screen with a screen brush. This design not only continues the blocking function of traditional anti-fouling screens but also adds a screen brush to address challenges such as clogging and damage from debris. The screen brush can dynamically clean the surface of the anti-fouling screen, keeping it unobstructed and effectively preventing the spread of silt and pollutants, thereby improving the anti-fouling effect and reducing subsequent cleaning costs. However, many of the aforementioned anti-fouling screens still suffer from a relatively complicated installation process.

[0004] Therefore, the development of new anti-fouling screen technologies is of great significance. Firstly, it helps protect the aquatic environment, reduces the pollution risks of aquatic engineering projects to the surrounding environment, and promotes sustainable development. Secondly, it can drive innovation and progress in anti-fouling screen technology, providing more efficient and convenient anti-fouling solutions for aquatic engineering projects. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a foldable plug-in anti-pollution screen that is easy to install and recycle, does not rely on traditional pontoons and anchor blocks for positioning, and can be folded and unfolded for convenient deployment and retrieval.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A foldable, insertable anti-fouling screen includes two parallel positioning posts. Each positioning post has an adjustable and detachable insert rod at its upper half. Each insert rod has a fixing element at its upper end and a sliding component at its middle. A geotextile anti-fouling curtain is mounted on one side of a folding frame. The upper left and upper right corners of the folding frame are connected to a fixing element to form a fixed hinge support, and the lower left and lower right corners are connected to a sliding component to form a sliding hinge support. This allows the folding frame to fold and unfold the geotextile anti-fouling curtain.

[0008] Preferably, the folding frame is composed of multiple folding panels connected by pins so that the folding panels can rotate around the pins, thereby realizing the folding and unfolding of the folding frame.

[0009] Preferably, each of the inserts is connected to a connecting plate on its outer side via two connecting sleeves, and each connecting plate has a cable tie hole.

[0010] Preferably, the connecting sleeve and the connecting plate are provided with corresponding bolt holes, and the connecting sleeve and the connecting plate are connected together by bolts passing through the bolt holes.

[0011] Preferably, the upper half of the positioning stake is a hollow structure, and the lower half of the insertion rod can be inserted into the positioning stake. At the same time, both the upper half of the positioning stake and the lower half of the insertion rod have multiple round holes. After the positioning stake and the insertion rod are inserted and fitted together, they can be locked in place by pins passing through the aligned round holes.

[0012] Preferably, the lower end of the positioning pile is a pointed tip to facilitate insertion into the soil.

[0013] Compared with the prior art, the foldable plug-in anti-fouling screen of this utility model has one or more of the following beneficial technical effects:

[0014] 1. This utility model is easy to fold and unfold, and can control the depth of anti-fouling operation, which improves some of the shortcomings of existing shallow water anti-fouling screens and greatly improves the efficiency of installation and recycling during construction.

[0015] 2. The traditional installation of antifouling screens is often quite troublesome, and the construction process is complicated when unfolding and retrieving the antifouling curtain. This utility model can install the antifouling curtain on the folding frame on the shore first. When laying, the folding frame can be unfolded directly, and when retrieving, it can be folded directly, which is simpler and more convenient than separate loading and unloading.

[0016] 3. This utility model utilizes positioning piles inserted into the soil to fix the position. The main body of the anti-pollution screen can be inserted into the positioning piles and pulled up and down, and fixed by the pins. This can control the depth of anti-pollution operation and eliminate the need for the floats and anchor blocks required by traditional floating anti-pollution screens due to the depth of operation. This makes the construction of anti-pollution screens more convenient and faster. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] This utility model relates to a foldable plug-in type anti-fouling screen, which is easy to install and recycle, convenient to unfold and retract, and the working depth of the anti-fouling curtain can be controlled.

[0025] like Figure 1-3 As shown, the foldable plug-in anti-pollution screen of this utility model includes two parallel positioning posts 10.

[0026] Preferably, the lower end of the positioning pile 10 is a pointed tip to facilitate insertion into the soil layer.

[0027] Each of the positioning stakes 10 has a detachable insert rod 8 on its upper half that is adjustable vertically relative to it. Specifically, as shown in the figure... Figure 4 and 5 As shown, the upper half of the positioning post 10 is a hollow structure, and the lower half of the insertion rod 8 can be inserted into the positioning post 10. Both the upper half of the positioning post 10 and the lower half of the insertion rod 8 have multiple round holes. After the positioning post 10 and the insertion rod 8 are inserted and fitted together, they can be locked in place by pins 9 passing through the aligned round holes.

[0028] Therefore, this utility model utilizes the positioning pile 10, which can be inserted into the soil to fix its position. The main body of the anti-pollution screen can be inserted into the positioning pile 10 and pulled up and down, and fixed by the pin 9. This not only controls the depth of anti-pollution operation, but also eliminates the need for the float of the traditional floating anti-pollution screen due to the working depth and the anchor block due to the need for stability, making the construction of the anti-pollution screen more convenient and faster.

[0029] Each of the inserted rods 8 has a fixing member 4 at its upper end and a sliding component 5 in its middle. A geotextile anti-fouling curtain 1 is installed on one side of the folding frame, and the upper left and upper right corners of the folding frame are respectively connected to a fixing member 4 to form a fixed hinge support, and the lower left and lower right corners are respectively connected to a sliding component 5 to form a sliding hinge support, so that the folding frame can drive the geotextile anti-fouling curtain 1 to fold and unfold.

[0030] Therefore, this invention facilitates folding and unfolding, improving upon some shortcomings of existing shallow water antifouling screens and greatly enhancing installation and retrieval efficiency during construction. Furthermore, this invention allows the antifouling curtain to be pre-installed on a folding frame on the shore; the frame can be unfolded directly during installation, and the curtain can be folded directly during retrieval, making it simpler and more convenient than separate loading and unloading.

[0031] Specifically, the folding frame is composed of multiple folding plates 2, and the folding plates 2 are connected by pins 3 so that the folding plates 2 can rotate around the pins 3, thereby realizing the folding and unfolding of the folding frame. In this way, at the left and right ends of the folding plate 2 at the upper left and upper right corners, the ends are connected to the fixing members 4 to form fixed hinge supports, and the ends of the folding plate 2 at the lower left and lower right corners are connected to the sliding components 4 to form sliding hinge supports.

[0032] Preferably, each of the insert rods 8 is connected to a connecting plate 7 via two connecting sleeves 6 on its outer side, and each connecting plate 7 has a cable tie hole. Thus, two adjacent foldable insert-type anti-fouling screens can be secured together by cable ties passing through the cable tie holes.

[0033] More preferably, the connecting sleeve 6 and the connecting plate 7 are provided with corresponding bolt holes, and the connecting sleeve 6 and the connecting plate 7 are connected together by bolts passing through the bolt holes. This makes it easier to install the connecting plate 7.

[0034] Before using the foldable plug-in anti-fouling screen of this utility model, the components are first assembled. The folding plate 2 and the geotextile anti-fouling curtain 1 are connected and installed with pins 3. The geotextile anti-fouling curtain 1 can then be unfolded and folded with the folding frame. Then it is assembled on the two plug rods 8 on the left and right sides, and the connecting plates 7 on both sides are installed and fixed. This completes the main body of an anti-fouling screen unit. After determining the location in the required working water area, insert positioning stakes 10 into the soil layer according to the set distance and orientation. Bring the folded antifouling screen units into the target area. First, unfold the main body of the antifouling screen from the folded state by pulling open the connecting plates 7 or the insert rods 8 at both ends. After the unfolded length is equal to the distance between the two positioning stakes 10, align the hollow holes in the upper half of the positioning stakes 10. Control the lower half of the insert rod 8 to insert into the upper half of the positioning stakes 10. Control the length of the insert rod 8 inserted into the positioning stakes 10 according to the antifouling depth required for the project construction. After determining the length, align the insertion holes between the two. Then, insert the pin 9 into the aligned insertion hole to lock the insert rod 8 so that it does not move up, down, left, or right. This can ensure the stability of the antifouling screen when working underwater and control the underwater antifouling area according to different specific construction water areas. Finally, use cable ties to bind the connecting plates 7 on adjacent antifouling screen units to improve stability and enclose the antifouling area. Finally, after the antifouling construction is completed, simply untie the cable ties, pull out the pin 9 between the insert rod 8 and the positioning stake 10, remove the main body of the antifouling screen, fold it back, and pull out the positioning stake 10. If the geotextile antifouling curtain 1 needs to be replaced after use, it can be disassembled from the folding frame. This antifouling screen facilitates the installation and retrieval of antifouling construction in shallow water areas, improves construction efficiency, replaces the role of anchor blocks and floats while retaining its main functions, and also offers greater flexibility.

[0035] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
