[0002] With the acceleration of urbanization and the continuous improvement of infrastructure, the maintenance and management of sewer systems, as an important component of urban drainage, are receiving increasing attention. However, sewer systems are also important habitats and activity channels for pests such as rodents. Rodents entering buildings through sewers can not only spread diseases but also damage building structures, affecting residents' quality of life and public health safety. Therefore, effectively preventing rodents from entering buildings through sewers has become an urgent problem to be solved.

[0003] Currently, there are various rodent-proof devices for sewers on the market, but most of them have problems such as complicated installation and inconvenient maintenance. For example, some rodent-proof nets are fixed and difficult to disassemble once installed, which means that cleaning and replacing the rodent-proof net requires damaging the original structure, increasing maintenance costs and time. In addition, although some rodent-proof devices are designed with a detachable structure, the disassembly process is cumbersome. Therefore, we need to propose a sewer rodent-proof net that is easy to install and disassemble. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A sewer rodent-proof net that is easy to assemble and disassemble includes a frame 1. The top of the frame 1 has a groove 2, and the rodent-proof net 3 is installed inside the groove 2. The top of the frame 1 is covered with a cover plate 4 to limit the rodent-proof net 3. The two sides of the cover plate 4 are detachably connected to the frame 1 by two sets of buckle components 6 to facilitate the assembly and disassembly of the rodent-proof net 3. An anti-climb component 5 is installed below the rodent-proof net 3 on the frame 1. The anti-climb component 5 is used to prevent rats from tearing the rodent-proof net 3.

[0024] Frame 1 is made of SUS304 stainless steel, and the rodent-proof mesh 3 is made of 316L stainless steel woven mesh.

[0025] In an optional embodiment: the snap-fit ​​assembly 6 includes a mounting groove 61 located at the center of the end of the cover plate 4, a rotating shaft 62 is rotatably mounted inside the mounting groove 61, and a snap-fit ​​63 is fixedly mounted on the outer wall of the rotating shaft 62.

[0026] It should be noted that the pivot 62 is a stainless steel pin, which is clearance-fitted with the mounting groove 61 (gap 0.1-0.3mm); the buckle 63 is made of spring steel sheet stamping, which can be engaged with the groove 7 after pressing. The elastic deformation of the buckle 63 generates a rebound force to ensure that it is locked and will not loosen.

[0027] Furthermore, a slot 7 adapted to the buckle 63 is provided on one side of the frame 1, and the buckle 63 is engaged inside the slot 7.

[0028] Furthermore, a finger groove 8 is provided on the side wall of the frame 1 below the slot 7, and a guide arc-shaped part 71 is provided at the entrance of the slot 7.

[0029] It should be noted that the inner wall of the slot 7 is provided with anti-slip texture, and the radius of curvature R of the arc part 71 is 3-5mm; the depth of the finger groove 8 is ≥8mm and the inner wall is chamfered, which conforms to the ergonomic finger grip curve. The arc part 71 allows the buckle 63 to slide into the slot 7 without alignment. The finger groove 8 allows operation while wearing gloves and is suitable for harsh environments such as rainy days.

[0030] In an optional embodiment: the anti-climb component 5 includes a metal grille 51 disposed within the frame 1 and located below the rodent-proof mesh 3, with downward-facing climbing spikes 52 at the bottom of the metal grille 51.

[0031] Furthermore, the metal grille 51 is composed of crisscrossing metal rods, and the climbing spikes 52 are made of stainless steel.

[0032] It should be noted that the diameter of the rod of the metal grid 51 is ≥2mm and the mesh size is ≤5mm; the climbing spikes 52 are distributed in a conical array with a spacing of 10-15mm between adjacent spikes, a spike length of 8-12mm, and the surface is sandblasted to increase friction. The dense climbing spikes 52 prevent rats from climbing with leverage, and the metal grid 51 does not affect the normal drainage of the sewer.

[0033] Furthermore, L-shaped limiting plates 10 are fixedly installed at the bottom of the four right angles of the cover plate 4, and L-shaped grooves 9 corresponding to the L-shaped limiting plates 10 are opened on the top of the frame 1, with the L-shaped limiting plates 10 inserted into the interior of the L-shaped grooves 9.

[0034] It should be noted that the fitting gap between the L-shaped limiting plate 10 and the L-shaped groove 9 is ≤0.2mm; when the cover plate 4 is pressed down, the L-shaped limiting plate 10 is first inserted into the groove 9 to achieve pre-positioning, and then the buckle 63 is closed.

[0035] Working principle: When using this utility model, the rodent-proof net 3 is installed in the groove 2 at the top of the frame 1 and fixed by the cover plate 4. The rodent-proof net 3 is made of high-density stainless steel and the aperture is strictly controlled within 8mm (recommended value) to ensure that it can block the passage of adult brown rats (head diameter of about 10mm) and maintain drainage efficiency ≥95%. The anti-climb component 5 is located below the rodent-proof net 3. If the rats try to bite the rodent-proof net 3 from below, the climbing spikes 52 of the anti-climb component 5 will pierce the rat's mouth or claws, causing physical damage and forcing it to give up the attack. At the same time, the rigid structure of the metal grid 51 can disperse the biting force and prevent the rodent-proof net 3 from deforming or breaking.

[0036] The cover plate 4 is connected to the frame 1 by two sets of buckle assemblies 6. During installation, the user places the cover plate 4 on the top of the frame 1, so that the L-shaped limiting plate 10 is inserted into the L-shaped groove 9 to achieve initial positioning. Then, the user presses the buckle 63 to make it slide into the groove 7 along the arc part 71 to complete the fixation.

[0037] During disassembly, the user inserts their finger into the finger groove 8 and pushes the buckle 63 upward to disengage it from the groove 7, allowing the cover plate 4 to be removed and the rodent-proof mesh 3 to be quickly replaced or cleaned.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
