[0007] As preferably, the second installation concave platform is concentric with the first installation concave platform, and the top of the second installation concave platform is lower than the top of the first installation concave platform.

[0008] As more preferably, the first installation concave platform is concentric with the mounting hole in the middle of the mounting seat.

[0009] As preferably, the highest part of the protruding part of the anti-falling net does not exceed the top of the second installation concave platform, and the lowest part of the recessed part of the anti-falling net does not lower than the bottom of the second installation concave platform.

[0010] Preferably, the limiting components are arranged on opposite sides of the fall arrest net. The limiting components on the same side are arranged at equal intervals along the edge of the fall arrest net, and the limiting components on both sides correspond one-to-one. The corresponding limiting components are symmetrical about the middle position of the fall arrest net.

[0011] Preferably, each of the limiting components includes a limiting block, which is horizontally tangent to the highest point of the corresponding fall arrest net protrusion. After the limiting block is fixedly engaged with the fall arrest net, it extends toward the side of the second mounting recess. The extension is provided with a limiting hole. The second mounting recess is provided with a corresponding limiting stud at the position corresponding to the limiting hole. A clamping nut is threaded onto the limiting stud.

[0012] More preferably, the fall protection net is hung in the second mounting recess by a limiting block.

[0024] The embodiments will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-5 As shown in the preferred embodiment 1, a rain grate for preventing objects from falling includes a mounting base 2. The mounting base 2 has a mounting hole in the center, and a first mounting recess 3 is provided at the top of the mounting hole. The first mounting recess 3 cooperates with the mounting hole to form a first mounting groove for installing the rain grate 1. This is a common installation structure and shape for existing rain grates 1. The first mounting recess 3 is a square ring shape, and a second square ring shape is provided inside the first mounting recess 3. External components pass through the first mounting recess 3 and the second mounting recess 4 in sequence and connect to the drain pipe. The second mounting recess 4 is detachably fixed with a fall-prevention net 5 by a limiting component, which facilitates installation and collection. The fall-prevention net 5 has a wave-shaped structure and is completely embedded in the inner ring of the second mounting recess 4. The recessed parts of the fall-prevention net 5 cooperate with the inner ring wall of the second mounting recess 4 to form a receiving groove 6. The protruding parts of the fall-prevention net 5 are provided with several evenly distributed overflow holes 7. The receiving groove 6 prevents items, large particles and domestic waste from entering the sewer, while the overflow holes 7 ensure the normal discharge of rainwater and clear liquid, reducing the impact on the urban river ecosystem.

[0026] The second mounting recess 4 is concentric and coaxial with the first mounting recess 3, and the top of the second mounting recess 4 is lower than the top of the first mounting recess 3. This ensures the stability and aesthetics of the installation and facilitates easy collection.

[0027] The mounting hole between the first mounting recess 3 and the mounting base 2 is concentric and coaxial. This ensures the stability and aesthetics of the installation and facilitates easy collection.

[0028] The highest point of the protrusion of the fall arrestor net 5 does not exceed the top of the second mounting recess 4, and the lowest point of the recess of the fall arrestor net 5 is not lower than the bottom of the second mounting recess 4. This ensures that the fall arrestor net 5 is completely embedded within the inner ring of the second mounting recess 4, preventing items from falling into the sewer through the holes on both sides of the fall arrestor net 5. This also ensures that the receiving groove 6 is relatively sealed. However, gaps are unavoidable between the fall arrestor net 5 and the second mounting recess 4. Therefore, drainage mainly relies on the overflow hole 7 to slow down the rainwater flow. Simultaneously, rainwater will gradually enter the sewer through the gaps.

[0029] In a preferred embodiment 2, the limiting components are respectively arranged on opposite sides of the fall arrest net 5. The limiting components on the same side are arranged at equal intervals along the side of the fall arrest net 5, and the limiting components on both sides correspond one-to-one. The corresponding limiting components are symmetrical about the middle position of the fall arrest net 5, ensuring the stability of the installation.

[0030] In a preferred embodiment 3, each limiting component includes a limiting block 8, which is horizontally tangent to the highest point of the corresponding protrusion of the fall arrest net 5. After the limiting block 8 is fixedly engaged with the fall arrest net 5, it extends toward the side of the second mounting recess 4. The extension is provided with a limiting hole 9. The second mounting recess 4 is provided with a corresponding limiting stud 10 at the position corresponding to the limiting hole 9. A clamping nut 11 is threaded onto the limiting stud 10.

[0031] In use, the fall protection net 5 is hung in the second mounting recess 4 by the limiting block 8. The extension of the limiting block 8 is supported on the top of the second mounting recess 4, and the limiting hole 9 on the extension is penetrated by the corresponding limiting stud 10. The extension is pressed and fixed with the top of the second mounting recess 4 by the clamping nut 11.

[0032] In a preferred embodiment 4, the wave of the fall protection net 5 is parallel to the short side of the first mounting recess 3.

[0033] The limiting components are respectively installed on both sides of the fall arrestor net 5 near the short side. This installation ensures that the limiting components on both sides are located on the corresponding waves, which is convenient for use and manufacturing.

[0034] As a preferred embodiment 5, this device is suitable for areas with many rain grates or where concentrated rainfall is not intense. The size and diameter of the overflow hole 7 are customized according to the actual situation. In places far from residential areas, without vendors, or where the possibility of large particles is small, the diameter can be appropriately enlarged.

[0035] When there are few rain grates or in areas with heavy concentrated rainfall, the density of the top overflow holes 7 can be increased or a mesh plate can be used to replace the top overflow holes 7 to ensure water discharge efficiency while retaining the overflow effect.

[0036] The working principle of this utility model:

[0037] The fall protection net 5 of the device is shaped into a wave-like structure and is completely embedded in the second mounting recess 4. The recessed part of the fall protection net 5 and the inner wall of the second mounting recess 4 form a receiving groove 6, which is used to receive debris entering the rain grate 1. It can not only prevent objects from falling in, but also allow accidentally dumped domestic or kitchen waste to settle and be intercepted in the receiving groove 6, preventing it from further entering the sewer system. Rainwater and supernatant are discharged through several overflow holes 7 on the protrusions of the fall protection net 5 to prevent rainwater accumulation. The receiving groove 6 prevents items, large particles and domestic waste from entering the sewer, while the overflow holes 7 ensure the normal discharge of rainwater and supernatant, and also slow down the rainwater flow rate to reduce the impact on the urban river ecosystem.

[0038] The device, through its limiting components, not only facilitates installation and disassembly but also ensures stability during use, guaranteeing the stable installation of the fall protection net.
