Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic construction facilities, and in particular relates to an anti-fouling screen which is convenient to deploy. Background Art

[0002] In hydraulic engineering construction, such as dredging and environmental protection operations, suspended solids generated during construction can cause secondary pollution to surrounding waters. This is especially true for reclamation projects, where anti-fouling screens must be installed at the outfall to reduce the impact of suspended solids on water quality. In environmental protection projects, anti-fouling screens prevent pollutants from spreading across the water surface and also collect surface pollutants. Generally, anti-fouling screens should be easy to prepare, deploy, and recycle. Furthermore, they should be durable once deployed in a specific area.

[0003] A typical problem with anti-fouling screens over long construction areas is the inconvenience of their deployment. Typically, an anti-fouling screen consists of an anti-fouling curtain and a buoyancy assembly located on top of the curtain. After the anti-fouling screen is deployed in the water, the buoyancy assembly floats on the water's surface, while the anti-fouling curtain is submerged. To facilitate its deployment, a counterweight can be installed at the bottom of the curtain. Furthermore, to anchor the anti-fouling screen, an anchor cable can be connected and an anchor can be dropped after deployment. Because the anti-fouling curtain and the buoyancy assembly are integrated into a single unit at the factory, and the buoyancy assembly is relatively large, the entire anti-fouling screen is difficult to store and takes up storage space. During on-site deployment, the anti-fouling screens become tangled and stacked, making it difficult to deploy and adjust their position in the water, impacting construction efficiency and effectiveness.

[0004] In summary, it is necessary to develop and design a new type of anti-fouling screen to solve the above technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-fouling screen that is easy to deploy, to improve the operational convenience of deploying and recovering the anti-fouling screen, and to improve the construction efficiency and construction effect.

[0006] The technical solution adopted by the present invention is: an anti-fouling screen that is easy to deploy, including an anti-fouling curtain, a top tube bag is provided on the top of the anti-fouling curtain, the top tube bag is separated by equidistantly spaced separation sutures to form a plurality of independent tube bag chambers, a core rod is provided in each tube bag chamber, a longitudinal curtain side tube bag with an open top and a sealed bottom is provided on the side of the anti-fouling curtain, a counterweight rod is inserted inside the curtain side tube bag; it also includes a plurality of floats combined with the top tube bag, the floats include two buoyancy blocks arranged opposite to each other, the two buoyancy blocks are detachably connected, and a transversely penetrating central clamping groove is provided in the middle of the inner side of the buoyancy block. After the two buoyancy blocks are docked and assembled, the top tube bag and the core rod are clamped between the two central clamping grooves.

[0007] Preferably, three groups of grooves arranged in a "pin" shape are provided on the two buoyancy blocks of the floating body. Transverse corresponding pin holes are provided on the bottom walls of the respective grooves, and connecting pins are inserted into each group of pin holes.

[0010] Preferably, the mandrel is made of plastic and has a hollow structure, and is integrally formed by blow molding process; the two buoyancy blocks of the floating body are each integrally formed by foaming process.

[0011] Preferably, the top edge of the anti-pollution curtain is turned downwards and transversely continuously stitched to form a top tube bag.

[0012] Preferably, a bottom reinforcing edge is provided at the bottom edge of the anti-pollution curtain by stitching or bonding.

[0013] The advantages and positive effects of the present utility model are:

[0014] The present utility model provides an anti-pollution screen that is convenient to deploy. Compared with the existing anti-pollution screen facilities, the anti-pollution curtain and the floating body at the top in the anti-pollution screen of the present utility model are of a detachable structure. When not in use and during transportation, the anti-pollution curtain and the floating body are disassembled and stored separately, and are combined in the use state. The anti-pollution curtain after removing the floating body can be wound around the reel configured on the ship facility without the obstruction of the floating body. During the deployment construction, the floating body is gradually added as the unwinding process progresses. Compared with the existing anti-pollution screen facilities that are assembled at the factory, the anti-pollution screen adopting the method of gradually unwinding and gradually adding the floating body makes the deployment work more orderly, and avoids the problems of inconvenience in deploying into the water and inconvenient adjustment of the position caused by stacking and entanglement of the existing anti-pollution screen. At the same time, the anti-pollution screen in the present utility model is also convenient to be recycled, stored and transferred in a winding manner, improving the construction efficiency and construction effect.

[0015] By providing a curtain side tube bag on the side of the anti-pollution curtain and inserting a counterweight rod into the curtain side tube bag, the main part of the anti-pollution screen, that is, the anti-pollution curtain located underwater, can be better unfolded and can better maintain its state under the action of water flow.

[0021] In order to further understand the content, features and effects of the present invention, the following embodiments are given to illustrate in detail.

[0022] See Figure 1 、 Figure 2 and Figure 3 The utility model is an anti-fouling screen that is easy to deploy, comprising an anti-fouling curtain 1, a top tube bag 2 being provided on the top of the anti-fouling curtain 1, the top tube bag 2 being separated by equally spaced separation sutures 3 to form a plurality of independent tube bag chambers, and a core rod 5 being provided in each tube bag chamber.

[0023] In this embodiment, the top tube bag 2 is formed by folding the top edge of the anti-fouling curtain 1 downward and sewing it continuously transversely to form the top tube bag 2. After the top tube bag 2 is formed, a mandrel 5 is placed inside the top tube bag 2. Longitudinal dividing stitches 3 are provided between adjacent mandrels 5, so that the mandrel 5 is confined within the tube bag cavity between adjacent dividing stitches 3.

[0024] As shown in the figure, the core rod 5 is cylindrical and has a length of 30 to 50 cm. Therefore, the top edge of the anti-fouling screen can be bent between adjacent core rods 5 and cannot be bent at the position where the core rod 5 is located. Therefore, the main part of the anti-fouling screen can be wound on the reel. Usually, the center line of the reel configured for construction ship equipment is vertical, and the reel is driven by hydraulic equipment to rotate forward or reverse. Therefore, when the anti-fouling screen is laid, Figure 1 The state shown in the figure is gradually unwound from the reel, and similarly, when it is recycled, Figure 1 In this way, the anti-fouling screen is more orderly in the process of deployment, recovery, storage, transfer and transportation compared with the existing anti-fouling screen, avoiding the problem of inconvenience in deployment and recovery caused by stacking and entanglement.

[0025] In this embodiment, the core rod 5 is made of plastic material and has a hollow structure. It is integrally formed by a blow molding process, so the core rod 5 can also provide a certain buoyancy effect.

[0026] On the side of the anti-pollution curtain 1, there is a longitudinal curtain side tube pocket 7 with an open top and a sealed bottom. Inside the curtain side tube pocket 7, a counterweight bar 8 is inserted. The counterweight bar 8 can be a steel bar. By setting the counterweight bar 8, the anti-pollution curtain 1 deployed underwater can be in a more fully unfolded state, and the ability of the anti-pollution curtain 1 to resist the action of water flow can be enhanced, and its state can be better maintained during use. Since the direction of the counterweight bar 8 is perpendicular to the length direction of the anti-pollution curtain, it is parallel to the center line of the reel on the ship facility. Therefore, when the main part of the anti-pollution screen is wound up, the counterweight bar 8 can be wound up on the reel synchronously. Of course, it can be imagined that the counterweight bar 8 can also be taken out when the main part of the anti-pollution screen is wound up, and the counterweight bar 8 can be gradually inserted and installed as the main part of the anti-pollution screen is gradually unreeled when the anti-pollution screen is deployed.

[0027] In this embodiment, a bottom strengthening edge 9 is provided at the bottom edge of the anti-pollution curtain 1 by stitching or bonding. The bottom strengthening edge 9 can be formed in the following ways: the bottom of the anti-pollution curtain 1 is turned up and continuously stitched horizontally, or another strip of the same material or different material as the anti-pollution curtain 1 is installed on the bottom edge of the anti-pollution curtain 1 by stitching or bonding. The function of setting the bottom strengthening edge 9 is to enhance the structural strength of the bottom edge of the anti-pollution curtain 1, improve the tensile capacity, and avoid the tearing problem that may occur when the anti-pollution screen is subjected to external pulling force.

[0028] It also includes a plurality of floating bodies 6 combined with the top tube pocket 2. The floating bodies 6 are detachably connected to the top edge of the main part of this anti-pollution screen. Therefore, the aforementioned core rod 5 is used to撑开 the top tube pocket 2, and after the top tube pocket 2 is撑开, it can be better combined with the floating bodies 6.

[0029] Such as Figure 2 and Figure 3 As shown in

[0030] In this embodiment, the two buoyancy blocks 6-1 of the floating body 6 are each integrally formed by a foaming process.

[0031] The two buoyancy blocks 6-1 are assembled in the following way: there are three groups of grooves 6-4 arranged in a "product" shape on the two buoyancy blocks 6-1 of the floating body 6 (one at the top and two on the left and right at the bottom). Transverse corresponding pin holes are provided on the bottom walls of each groove 6-4, and connecting pins 6-3 are inserted into each group of pin holes. In this embodiment, one end of the connecting pin 6-3 has a collar and the other end is a tip. A strip groove is provided in the middle of the connecting pin 6-3, and a convex platform is provided outside the tip.

[0032] The tip at the front is used to pierce the anti-fouling curtain 1, while the collar at the rear facilitates the installation and removal of the pin. Due to the central groove, the left and right blades of the connecting pin 6-3 are squeezed together during the horizontal installation of the connecting pin 6-3, allowing the connecting pin 6-3 to penetrate to the other side. When the squeezing effect subsides, the left and right blades of the connecting pin 6-3 rebound outward under their own elastic force, and the boss outside the tip engages the outside of the pin hole, completing the connection between the buoyancy blocks 6-1. To release the connection, the tip is engaged and pulled outward through the collar.

[0033] In this embodiment, transverse connecting holes 6-2 are provided at the four corners of the two buoyancy blocks 6-1, wherein the top connecting hole 6-2 is used to connect the displacement cable 4, and the ship pulls and displaces the deployed anti-fouling screen through the displacement cable 4, and the bottom connecting hole 6-2 is used to connect the anchor cable 10, and an anchor block 11 is provided at the end of the anchor cable 10. The anchor block 11 is thrown into the water body on the side of the anti-fouling screen and sinks to the bottom of the water. A group of anchor cables 10 and anchor blocks 11 are set at a certain length to anchor the position of the anti-fouling screen to avoid arbitrary displacement under the action of water flow.

[0034] Deployment and recycling methods:

[0035] Before deployment, the main part of the anti-fouling screen is rolled up on the reel configured on the construction vessel. When it reaches the deployment starting position in the deployment water area, the unwinding is started, and the main part of the anti-fouling screen is slowly unwound. As the unwinding progresses, the floating body 6 is installed at the top edge, as shown in FIG. Figure 1 As shown in , the float 6 can be installed on the outside of a single core rod 5, or can be installed between two adjacent core rods 5, and a counterweight rod 8 is inserted into the curtain side tube bag 7;

[0036] As the buoy 6 and counterweight rod 8 are unwound and installed, the construction vessel moves along the deployment path, installs the anchor cable 10 and anchor block 11 for the buoy 6 at the appropriate position and drops them, and finally completes the deployment of the entire anti-fouling screen when it moves to the terminal position.
