Background Art
[0002] During flood season, debris such as plant debris and household garbage enters the reservoirs of some large hydropower stations, impacting the ecological environment. Currently, most hydropower stations use trash racks to intercept floating debris at their water intakes. However, when these debris accumulates, the water flow at the station's intake is reduced, impacting unit output and potentially even causing the trash racks to collapse, leading to accidents and jeopardizing the safe operation of the station.

The main cable is connected to the floating box through a buckle, and the lower part of the floating box is connected to the grid. The floating box floats on the water surface under the action of the buoyancy of the main cable tension machine itself, thereby achieving the effect of intercepting floating objects above and below the water surface; Patent No. CN210797485U discloses a net-type floating interception equipment, which consists of fan blades, interception rods, columns and classification nets. The fan blades are mounted on the interception rods, and the classification nets are located between the columns, which can effectively realize the classification and interception of floating objects; Patent No. CN110984095A discloses a square hollow structure floating interception body. The floating body floats on the water surface by its own buoyancy, which can realize the interception of floating objects in the entire section of the river, and has the characteristics of safe and convenient floating cleaning work.
[0004] Existing technologies can basically realize the function of adaptive water level floating object interception in the reservoir area.

[0052] The embodiments of the present invention will be further described below with reference to the accompanying drawings.
[0053] Example 1:
[0054] See also Figure 1-6A combined float-arresting structure of pontoons and wire meshes comprises a plurality of pontoons 1 for floating on the water surface, with adjacent pontoons 1 connected by connecting buckles 3; the connecting buckles 3 are fixed to the top middle part of the pontoons 1 through an outwardly convex cover plate 2; an upper wire mesh structure 6 for intercepting surface floating objects is installed on the top of each pontoon 1; a lower wire mesh 4 for intercepting underwater floating objects is installed on the bottom of each pontoon 1; two adjacent pieces of lower wire meshes 4 are clamped and connected by multiple groups of rope clamps 7 to form a whole structure; a heavy hammer 5 is fixed to the bottom end of the lower wire mesh 4. By adopting the above-mentioned combined float-arresting structure, it can be automatically raised and lowered as the water level changes, and each float unit is easy to repair and replace, which improves the full life cycle of the float-arresting structure while ensuring the realization of the float-arresting function.
[0055] Furthermore, the buoy 1 includes a buoy body 101, which has a semi-cylindrical hollow structure and is filled with polyurethane foam. A concave semi-cylindrical slot 102 for mounting the connecting buckle 3 is provided in the middle of the top plane of the buoy body 101. A wire mesh mounting hole 104 for mounting the lower wire mesh 4 is machined at the bottom of the buoy body 101. The buoy 1 described above can effectively float on the water surface and can be raised and lowered according to changes in the water level, thereby achieving a comprehensive interception effect. Furthermore, the semi-cylindrical hollow structure ensures that the buoy 1 always floats upright on the water surface.
[0056] Furthermore, an arcuate groove 103 is provided at one end of the concave semi-cylindrical slot 102 on the top of the buoy body 101. The arcuate groove 103 can be used to accommodate the connecting buckle 3, thereby ensuring that no gaps are formed between adjacent buoy bodies 101 during assembly, preventing floating objects from passing through the gaps and ensuring the interception effect.
[0057] Furthermore, the upper steel mesh structure 6 includes fixed suspension columns 601 secured to the top of the buoy 1, with an upper steel mesh 602 secured between the fixed suspension columns 601. This upper steel mesh structure 6 effectively intercepts floating objects on the water surface. Furthermore, the use of an assembled connection structure facilitates the securement and installation of the upper steel mesh structure 6.
[0058] Furthermore, the connecting buckle 3 includes a connecting rod 302, which is disposed within the concave semi-cylindrical slot 102 of the buoy 1. A connecting ring 301 is disposed at one end of the connecting rod 302, and a U-shaped connecting rod 303 is disposed at the other end. The top of the U-shaped connecting rod 303 is provided with a threaded cylindrical hook 305 for mating with the adjacent connecting ring 301, and a locking nut 304 is mounted on the threaded cylindrical hook 305. The U-shaped connecting rod 303 is disposed on the side of the arc-shaped groove 103. The connecting buckle 3 described above enables reliable connection between adjacent buoys 1. It also facilitates assembly and disassembly, improving installation and disassembly efficiency. When assembly is required, the threaded cylindrical hook 305 is hooked and connected to the connecting ring 301, and then locked with the locking nut 304 to achieve a locking and fixing effect.
[0059] Furthermore, the convex cover plate 2 includes a cover plate body 203, and the central part of the cover plate body 203 is processed with a convex semi-cylindrical groove 201. The two side wings of the cover plate body 203 are pressed and fixed to the middle part of the top of the buoy 1 by bolts 202 and gaskets 204. The above-mentioned convex cover plate 2 can be used to press and fix the connecting buckle 3 to the top of the buoy 1, and it is convenient for its disassembly and assembly. In the specific installation process, the connecting buckle 3 is set inside the concave semi-cylindrical groove 102 of the buoy 1, and then the cover plate body 203 is pressed on the top of the connecting buckle 3, and then the cover plate body 203 is pressed and fixed by bolts 202 and gaskets 204.
[0060] Furthermore, the width of the lower steel mesh 4 is longer than the length of the buoy 1. A weight 5 is hung at the bottom of the lower steel mesh 4 to prevent the mesh from floating up under the action of water flow.
[0061] Preferably, Figure 2 As shown, the main structure of the buoy 1 is made of lightweight, environmentally friendly PE material, except for the upper steel mesh, which is made of corrosion-resistant, high-strength steel. The upper steel mesh has a small aperture to facilitate intercepting small floating objects on the water. To reduce the distance between the buoys and prevent floating objects from passing between them, an arc-shaped groove 103 is formed on the right end of the buoy.
[0062] Preferably, Figure 3 As shown, the convex cover plate 2 is made of lightweight environmentally friendly PE material, and is equipped with screws and washers for fixing the connecting buckles passed through.
[0063] Preferably, Figure 4As shown, the connector is made of corrosion-resistant, high-strength steel, with a ferrule at the left end and a U-shaped hook at the right. The hook has a threaded top and accessories including a nut and washer. Between the connectors, the ferrule fits over the U-shaped hook. A washer and nut are located on the upper outer portion of the U-shaped hook to secure the ferrule and prevent it from falling off. The ferrule is a hollow cylindrical structure that rotates around the U-shaped hook under the action of water flow.
[0064] Preferably, Figure 5 As shown, the lower wire mesh and weight are both made of corrosion-resistant, high-strength steel. Because floating objects are generally larger underwater, the mesh aperture can be adjusted to be larger than that of the upper mesh, but not too large to prevent floating objects from passing through the mesh. Steel rope clamps are installed at each end of the lower mesh to connect adjacent meshes and prevent floating objects from passing between them. A weight is suspended below the mesh to prevent it from being lifted by the current.
[0065] Preferably, the exterior of the steel material components are all painted to reduce the degree of oxidation corrosion.

[0070] Step 1.2, transportation of a single floating barrier structure:
[0071] Calculate the number of individual interception structures required based on the width of the water area to be intercepted, and use a transport ship to transport the assembled individual interception structures to the water area where they need to be installed;

[0077] During normal operation, the integrated floating interception structure will always float on the water surface, intercepting floating objects on the water surface through the upper wire mesh structure 6 located on the water surface, and intercepting floating objects within a certain depth underwater through the lower wire mesh 4.
[0078] When it is necessary to unload the floating structure, the following steps are included:
[0079] Step 2.1: Use a hook to hook up the wire mesh 4 at the bottom of the floating barrier to be replaced and remove the rope clamp 7 associated with it, so that the floating barrier is no longer connected to other floating barriers;
[0080] Step 2.2: Use the hook to drag the lower wire mesh 4 onto the boat first to reduce the weight of the floating body;
