[0029] like Figure 1 As shown, the flood control grille includes a body, a plug-in portion, a plug-in slot and a buckle portion. The body is roughly plate-shaped, and a through hole is provided on the body; the plug-in portion is arranged at the edge of one side of the body; the plug-in slot is arranged on the body, close to the side of the plug-in portion, and the plug-in portion is a protruding structure that can match the plug-in slot on another flood control grille; along the edge where the plug-in portion is located toward the other side edge of the body, the opening rate of the through hole gradually increases; when working, the first flood control grille is placed flat on the ground, and the second flood control grille is installed on the plug-in slot of the first flood control grille through the plug-in portion. Buckle portions are correspondingly arranged on both sides of the body, and when working, adjacent flood control grilles are connected and fixed by the buckle portions.

[0030] In this embodiment, a plurality of through holes are provided on the main body so as to effectively intercept floating objects without affecting the water flow and reduce the impact force of the water flow on the flood control grille; a plurality of flood control grilles can be connected in series by plugging in to form a continuous flood barrier; the opening rate of the through holes gradually increases along the edge where the plug-in portion is located toward the edge of the other side of the main body, which means that the through holes close to the plug-in portion are smaller, while the through holes away from the plug-in portion are larger. Such a design can provide denser protection near the embankment and allow more water to pass through away from the embankment, thereby reducing the overall pressure on the flood control grille.

[0031] The modular design of this embodiment makes installation and disassembly very convenient and quick. In an emergency, it can be quickly deployed to areas where floods may reach, thereby effectively preventing floods. Secondly, the gradually enlarged design of the through holes can effectively respond to the impact of floods, which can not only prevent large floating objects from passing through, but also reduce the pressure on the flood control grille and extend its service life. In addition, through the design of the buckle part, multiple flood control grilles can be connected into a whole to form a more stable flood control system.

[0032] In a further embodiment, a support rod mounting portion is provided on the back water side of the main body, and the mounting portion may be a prefabricated groove, a socket or a fixing buckle. The support rod is made of metal and, when working, is connected with the support rod to form a supporting fixing structure to provide a stable supporting force.

[0033] When a flood comes, the support rods can resist the impact of the water flow and the impact of floating objects, keeping the flood control grille in a stable position. In addition, the surface of the support rods can be coated with anti-corrosion materials to adapt to various harsh outdoor environments.

[0034] In this embodiment, the support rod can effectively resist the lateral impact force of the flood, ensuring that the flood control grille can remain stable even in a strong current and will not be washed away; through the quick plug-in connection method, the support rod can be quickly installed or removed, which is convenient for quickly deploying flood control measures before the flood comes; the material and surface treatment of the support rod make it have good corrosion resistance and durability, suitable for long-term outdoor use. The design of the support rod mounting part improves the stability and safety of the flood control grille.

[0035] like Figure 2 As shown, in a further embodiment, the bottom of the first flood control grid is provided with anti-skid strips for increasing friction with the ground. These anti-skid strips can be made of rubber, silicone or other materials with a high friction coefficient. The shape of the anti-skid strips can be strips, raised dots or any other structure that can increase friction. The anti-skid strips are evenly distributed at the bottom of the grid to ensure that the contact area with the ground is maximized, thereby providing stronger friction.

[0036] When floods come, the anti-slip strips can effectively resist the impact and horizontal thrust of water flow on the flood control grille, preventing the grille from being pushed by the water flow. To further enhance the effect, the bottom of the anti-slip strips can be designed with irregular textures or small protrusions, which can provide better grip on mud or sandy ground.

[0037] This embodiment improves the overall stability and safety of the flood control system through the anti-slip strips; at the same time, it can be quickly laid on the ground without the need for additional fixing equipment, which is convenient for rapid response to flood emergencies and has good economy and adaptability.

[0038] In a further embodiment, a rope hanging hole is preset on the body of each flood control grille, and when working, the first flood control grille and the second flood control grille form a tensioning structure through the rope. The two ends of the rope can be fixed by knots or special tensioners to ensure that the tension of the rope is moderate, neither too tight to cause grille deformation nor too loose to affect the effect.

[0039] By connecting multiple grilles into a whole through ropes, the impact force of floods can be effectively dispersed, and the overall stability and impact resistance can be improved; the length and tension of the ropes can be flexibly adjusted according to the site conditions, so that the flood control grilles can adapt to different terrains and flood conditions; the design of the rope hanging holes allows the flood control grilles to be quickly connected, which is convenient for the rapid deployment of flood control measures before the flood comes; by using relatively low-cost ropes and simple hanging hole designs, effective tensioning functions can also be provided without increasing too much cost. This embodiment further improves the stability and safety of the flood control grille through the design of rope hanging holes and tensioning structures.

[0040] In a further embodiment, a storage space is provided on the main body for accommodating the draw cord. The size of the storage space should be sufficient to accommodate a draw cord of the required length, while ensuring that the draw cord is easily accessible and convenient to take out and store. The material of the storage space may be the same as that of the main body, or other water-resistant and weather-resistant materials to ensure durability in outdoor environments. When the flood control grille is not in use, the draw cord can be neatly wound and stored in the storage space to prevent the draw cord from becoming messy or being affected by the external environment. The storage space may be designed to be open, or it may have a cover or door buckle to prevent dust and sand from entering and keep the draw cord clean and tidy.

[0041] The storage space makes the storage and management of the drawstrings more orderly. The staff can quickly take out or store the drawstrings, which improves the efficiency of deployment and disassembly. At the same time, the storage space can also protect the drawstrings from the influence of the external environment, such as rain, direct sunlight, etc., extending the service life of the drawstrings. The neatly stored drawstrings will not cause chaos on site, reducing the safety hazards of the staff during operation.

[0042] like Figure 3 As shown, in a further embodiment, a magnetic strip is provided on the water-bearing surface of the body, and the magnetic strip is arranged longitudinally along the grille in the form of an embedded magnet to facilitate the laying and fixing of the waterproof cloth. The material of the magnetic strip needs to be selected from materials with good magnetic properties, such as ferrite or neodymium iron boron, which can provide sufficient adsorption force to ensure that the waterproof cloth will not fall off due to the impact of floods. When working, it is used to press the waterproof cloth onto the body; the magnetic strip is arranged longitudinally, and the anti-slip strip is arranged horizontally.

[0043] When deploying flood control grilles, workers first lay tarpaulins on the water-bearing surface of the grilles, and then use the adsorption force of magnetic strips to fix the tarpaulins in place. The tarpaulins can be made of materials with good waterproof properties such as PVC or TPU to ensure that they will not be damaged by prolonged immersion in water. The magnetic strips can firmly fix the tarpaulins on the grilles to prevent floodwaters from penetrating the gaps, thereby improving the overall waterproof effect.

[0044] This embodiment improves the waterproof performance and stability of the flood control grille through the magnetic pressure strip.

[0045] In a further embodiment, in the design of the flood control grid, ABS, PP or PE can be selected as the main material of the body. These materials are not only light and easy to process and shape, but also can withstand long-term exposure to the sun and rain without deformation or fading. ABS has good toughness and hardness, and is suitable for making parts with complex structures. PP has a lighter weight due to its lower density and is suitable for large-area applications. PE is suitable for use in harsh environments due to its excellent chemical resistance and impact resistance.

[0046] During the production process, the body of the flood control grille can be manufactured by injection molding or extrusion molding. These polymer materials are able to flow after heating and can fill the corners of the mold to form the desired shape. After cooling and solidification, the material will maintain its shape and have a certain strength and rigidity. In addition, UV inhibitors and antioxidants can be added to the material to improve its weather resistance when used outdoors.

[0047] This embodiment selects ABS, PP or PE as the material of the flood grille body, so that the flood grille is relatively stable in the environment and is not prone to chemical changes, reducing the risk of environmental pollution. At the same time, the cost of these materials is relatively low, which can reduce the overall production cost without sacrificing performance. ABS, PP and PE are all recyclable materials, which are conducive to resource recycling and environmental protection. The material of the flood grille body can also be fiberglass, which is a composite material also called fiber reinforced plastic (FRP), which is mainly composed of glass fiber and synthetic resin. This not only ensures the performance and durability of the flood grille, but also brings economic and environmental benefits. Figure 1 , Figure 4 and Figure 5 As shown, in a further embodiment, the through holes on the flood control grille are circular or hexagonal, or triangular. When designing a flood control grille, the appropriate through hole shape can be selected according to the specific application scenario and goal. The circular through holes can maintain the stability of the structure when subjected to uniform pressure due to their symmetry; the hexagonal through holes provide greater strength and compression resistance under the same area due to their honeycomb arrangement; and the triangular through holes perform well in resisting tensile and compressive forces due to the structural characteristics of their corner points.

[0048] During the manufacturing process, high-precision mold injection technology can be used to ensure that the shape of the through holes is accurate. These through holes can be distributed unevenly as needed to adapt to different water flow conditions and interception requirements.

[0049] These shapes of through holes can allow water to flow smoothly without affecting the overall strength of the flood control grid, reducing the impact of water flow on the flood control grid. Among them, hexagonal and triangular through holes can better disperse the force when under pressure due to their geometric characteristics, thus improving the stability of the flood control grid. The size and shape of the through holes can be designed according to actual needs to effectively intercept floating objects of different sizes and protect the land and facilities behind them.

[0050] The shape selection of the through holes in this embodiment is of great significance for improving the performance and efficiency of the flood control grid.

[0051] In a further embodiment, the first flood control grille and the second flood control grille are provided with tension rope hanging holes and U-shaped lock hanging grooves. The tension rope hanging holes are usually located at the upper edge of the grille, while the U-shaped lock hanging grooves are provided on the side or bottom of the grille. The size and shape of these hanging holes and hanging grooves should match the tension rope and U-shaped lock used to ensure the reliability of the connection.

[0052] When deploying the flood control grille, the staff will pass the tension rope through the hanging hole of the first grille, then cross it to the second grille and secure it with a U-lock. The U-lock design needs to be simple and easy to operate, while having sufficient strength to withstand the tension force. This connection method not only provides a stable physical lock, but is also easy to operate when it needs to be disassembled or reconfigured.

[0053] In this embodiment, multiple grilles are connected by tension ropes and U-locks to form a whole, which enhances the resistance to flood impact and improves the stability of the overall structure. This connection method makes the deployment and disassembly of flood control grilles quick and easy, and improves the efficiency of responding to flood emergencies. Whether it is flat or irregular terrain, the stable laying of flood control grilles can be ensured by adjusting the length and tension of the tension ropes. The design of the tension rope hanging hole and the U-lock hanging groove plays a key role in improving the stability and safety of the flood control grille, while also taking into account economy and ease of operation.

[0054] In some embodiments, the first flood control grid and the second flood control grid have the same structure. Of course, in other embodiments, the first flood control grid and the second flood control grid may be different.

[0055] like Figure 6As shown, in another embodiment of the present application, the change in porosity includes continuous change and step change. For example, the case of continuous change is as follows, and the porosity of each row is different. The case of step change is as follows, the porosity of the 1st and 2nd rows is the same, the porosity of the 3rd and 4th rows is the same, and the porosity of the 5th and 6th rows is the same. The porosity of the 2nd and 3rd rows, and the 4th and 5th rows increases or decreases according to the distribution law of the porosity. Or the porosity of rows 1, 2, and 3 is the same, and the porosity of rows 4, 5, and 6 is the same. The porosity of rows 3 and 4 is different. It should be noted that the arrangement can be made in a vertical and horizontal direction, or it may not be strictly arranged in a vertical and horizontal direction. For example, the openings in a certain area are oblique, and there is no strict longitudinal or transverse arrangement between adjacent openings.

[0056] In another embodiment of the present application, the porosity may be overall, that is, the porosity is constantly changing from one side to the other, or it may be local, that is, only a portion of the porosity is changing according to a predetermined rule.

[0057] In another embodiment of the present application, adjacent flood control grates are connected and fixed by horizontal bolts or vertical bolts.

[0058] In another embodiment of the present application, the cross-section of the plug-in portion may be a triangle, a square, a hexagon, an octagon or a special-shaped structure.

[0059] In another embodiment of the present application, the opening rate is greater than or equal to 80%.

[0060] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
