Description

Technical Field

[0001] This application relates to the field of protective device technology, specifically to a rodent-proof device. Background Technology

[0002] With the construction and operation of subways, underground electrical rooms, and other public facilities, the problem of pests such as rats has become increasingly serious, especially in environments such as electrical rooms and equipment rooms. Rats can not only damage electrical equipment but also pose hygiene hazards and fire risks. To reduce the damage caused by rats to electrical equipment, rat-proof devices have been installed to prevent rats from entering the rooms.

[0003] Existing rodent-proof devices, such as rodent barriers, metal mesh, and threshold rodent-proof devices, typically have a design height of around 500mm. People need to step over these barriers to enter the room, which can easily lead to collisions with the barriers or falls, causing inconvenience to passage.

[0004] In addition, other rodent-proof devices require additional installation space, which affects the effective use of passage areas, reduces the space available for passage, and is easily affected by changes in the external environment (such as equipment vibration, changes in rodent behavior, etc.), making it impossible to work stably for a long time.

[0005] Therefore, the existing rodent-proof device structure has room for further improvement. Utility Model Content

[0006] In view of this, existing rodent-proof devices cannot simultaneously achieve both rodent-proof functionality and ease of passage, resulting in inconvenience. This application provides a rodent-proof device that incorporates a rotating mechanism installed inside a trap pit. The surface of the rotating mechanism is flush with the ground, allowing people to pass without needing to cross a threshold. The rotating mechanism can rotate relative to the trap pit, causing rodents attempting to pass to slip into the pit due to the unbalanced rotation, effectively preventing escape.

[0007] To achieve the above objectives, this application provides the following technical solution: a rodent-proof device, comprising a rotating mechanism, a protective component, and a trap pit set on the ground, wherein the rotating mechanism is connected to the protective component, and the protective component is connected to the side wall of the trap pit;

[0008] The rotating mechanism is installed on the side of the trap pit near the equipment door, and the rotating mechanism is capable of rotating relative to the protective assembly;

[0009] The rotating mechanism is flush with the ground.

[0010] Compared to existing technologies, this invention includes a rotating mechanism and a protective component. The rotating mechanism can rotate relative to the protective component. When a mouse falls into the trap and attempts to climb onto the rotating mechanism to escape, the mechanism rotates, causing the mouse to lose its balance and become unable to stand stably on it, resulting in the mouse slipping or falling into the trap. This ensures that the mouse cannot escape after the rotating mechanism rotates, effectively limiting the mouse's range of movement, increasing the success rate of capture, and thus effectively preventing it from entering indoor spaces. Furthermore, the rotating mechanism is on the same plane as the ground, reducing the risk of people falling or tripping, as the absence of a height difference makes it easier for people to maintain their balance. It also reduces the space required for passage, improving the utilization of passage space.

[0011] In some embodiments of this application, the rotating mechanism includes a rotating member and a connecting rod arranged coaxially, the rotating member being rotatably connected to the connecting rod, and the connecting rod being fixedly connected to the protective component.

[0012] In some embodiments of this application, the rotating mechanism further includes a support member connected to the inner wall of the rotating member, and the connecting rod is at least partially located within the support member;

[0013] The support member is provided with a socket for inserting the connecting rod. The socket cooperates with the connecting rod to realize the connection between the connecting rod and the support member.

[0014] Furthermore, the protective assembly includes a protective member connected to the side wall of the trap pit, and the connecting rod is connected to the protective member;

[0015] There are two protective components, which are located on opposite side walls of the trap pit.

[0016] Furthermore, the protective component is provided with a groove, and the connecting rod is connected to the protective component through the groove. The groove and the connecting rod are correspondingly arranged, and the connecting rod is placed in the groove.

[0017] In some embodiments of this application, the protective assembly further includes a base plate, and a first side plate and a second side plate arranged in parallel, wherein the first side plate and the second side plate are both connected to opposite sides of the base plate;

[0018] The rotating mechanism is located between the first side plate and the second side plate, and both the first side plate and the second side plate are connected to the side wall of the trap pit.

[0019] The two protective components are located on different sides of the base plate.

[0020] Furthermore, the support member is also provided with a protrusion, one end of which is connected to the support member and the other end is connected to the inner wall of the rotating member, and the protrusion protrudes towards the rotating member;

[0021] There are at least two protrusions, and two adjacent protrusions are symmetrically arranged along the center line of the support member.

[0022] Furthermore, the groove facing the base layer has an arc-shaped structure;

[0023] The diameter of the groove is L1, and the outer diameter of the connecting rod is L2;

[0024] Where L1≥L2.

[0025] Furthermore, the distance between the rotating mechanism and the first side plate near the equipment door is 1 to 5 mm;

[0026] The distance between the side of the rotating mechanism away from the equipment door and the second side plate is 5.5 to 7 cm.

[0027] Furthermore, the rotating component has a smooth surface and is made of a high-strength, corrosion-resistant material.

[0028] The rodent-proof device of this application has at least the following technical effects:

[0029] 1. By setting up a support component, which is connected to the inner wall of the rotating component, the support component can effectively provide support force, enhance the stability and structural strength of the rotating component, and prevent the risk of deformation or loosening during use. The support component is provided with a socket for inserting a connecting rod. The support component and the connecting rod cooperate to realize the connection between the connecting rod and the support component, so that the support component and the connecting rod can be easily assembled and disassembled, and the structure is simple.

[0030] 2. By setting grooves on the protective components, the connecting rods are connected to the protective components through the grooves. The arc design of the grooves facing the base layer can make the protective components more evenly stressed, reduce local stress concentration, and improve the overall stability of the structure. The diameter of the grooves is at least equal to or larger than the outer diameter of the protective components. This can effectively prevent the protective components from getting stuck in the grooves or from being unable to be placed smoothly, reduce errors during the installation process, and ensure the accurate positioning of the protective components.

[0031] 3. By setting protrusions on the support, the protrusions are connected to the inner wall of the rotating part. There are at least two protrusions, and the two adjacent protrusions are designed symmetrically along the center line of the support. Multiple protrusions can evenly distribute the weight of the rotating part, reduce local stress concentration, reduce the risk of structural damage, and also improve the vibration resistance of the rotating part, making it more stable when subjected to external impact or vibration.

[0032] 4. By setting the distance between the side of the rotating mechanism closest to the equipment door and the first side plate to 1-5mm, rats can be effectively prevented from escaping from the side of the rotating mechanism closest to the equipment door. The distance between the side of the rotating mechanism away from the equipment door and the second side plate is 5.5-7cm. When people step on the rotating mechanism, their feet will not fall into the trap pit, thus improving people's safety. Attached Figure Description

[0045] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0046] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0047] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0048] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 7 illustrate.

[0049] This embodiment provides a rodent-proof device, which is applied in the field of protective device technology, specifically, as follows: Figures 1 to 7 As shown, the rodent-proof device is suitable for use in subway stations. Since the surface finish of the subway station concourse is typically 150mm thick, trap pits 3 can be installed. The trap pits 3 are positioned in front of the equipment doors leading to equipment rooms or electrical rooms. The rodent-proof device is installed inside the trap pits 3, without protruding from the ground, effectively preventing workers from tripping and facilitating equipment transportation later. The rodent-proof device includes a rotating mechanism 1 and a protective component 2. The rotating mechanism 1 can be made of high-strength, corrosion-resistant material. The rotating mechanism 1 is connected to the protective component 2, which is connected to the side wall of the trap pit 3. The rotating mechanism 1 is installed inside the trap pit 3, positioned on the side of the trap pit 3 closest to the threshold. The rotating mechanism 1 can rotate relative to the protective component 2. When a rat falls into the trap pit 3 and attempts to stand on the rotating mechanism 1 to escape, the rotating mechanism 1 rotates, causing the rat to lose its balance and become unable to stand stably on it, resulting in the rat slipping or falling into the trap pit 3. This ensures that the rat cannot escape after the rotating mechanism 1 rotates, effectively limiting the rat's activity range, increasing the success rate of capture, and thus effectively preventing it from entering the building. Among them, the rotating mechanism 1 is on the same plane as the ground, which can reduce the risk of people falling or tripping, because the absence of height difference makes it easier for people to maintain their balance. It can also reduce the space of the passage area and improve the utilization rate of the passage space.

[0050] Specifically, such as Figures 2 to 5As shown, the rotating mechanism 1 includes a rotating component 11, a connecting rod 12, and a support component 13 arranged coaxially. The rotating component 11 is a roller structure with a smooth surface and can be made of high-strength corrosion-resistant material. The connecting rod 12 and the support component 13 can both be made of stainless steel. The connecting rod 12 is fixedly connected to the protective component 2. The rotating component 11 is sleeved on the connecting rod 12, and the rotating component 11 and the connecting rod 12 are rotatably connected. The rotating component 11 can rotate relative to the connecting rod 12. When a mouse tries to step on the rotating component 11 to escape, the rotation of the rotating component 11 will prevent the mouse from having any foothold and thus prevent it from climbing onto the rotating component 11. The whole process does not require much human intervention and automatically achieves the rodent-proof function, making it convenient and efficient to use. The support member 13 is connected to the inner wall of the rotating member 11, and the connecting rod 12 is at least partially located inside the support member 13. The support member 13 can effectively provide support force, enhance the stability and structural strength of the rotating member 11, and prevent the risk of deformation or loosening during use. The support member 13 is provided with a socket for the connecting rod 12 to be inserted. The support member 13 and the connecting rod 12 cooperate to realize the connection between the connecting rod 12 and the support member 13, making it easy to assemble and disassemble the support member 13 and the connecting rod 12, with a simple structure. For further safety, the rotating member 11 is painted with yellow and black warning paint as a visual reminder. This color combination is commonly used in warning signs and can attract people's attention, reminding them to walk carefully and avoid approaching traps.

[0051] Furthermore, such as Figure 5 As shown, the support member 13 is provided with a socket for inserting the connecting rod 12. The socket mates with the connecting rod 12 to connect the connecting rod 12 to the support member 13. The design of the socket ensures that the connecting rod 12 can be securely inserted into the support member 13, thereby achieving a firm connection. The diameter of the socket matches the outer diameter of the connecting rod 12, ensuring a tight fit when the connecting rod 12 is inserted, preventing the connecting rod 12 from loosening or falling off due to vibration or external force during use. Furthermore, the installation and disassembly process of the connecting rod 12 and the socket is simple and convenient, allowing users to quickly maintain or replace the connecting rod 12, thus improving the efficiency of the device. The support member 13 is also provided with a protrusion 14. One end of the protrusion 14 is connected to the support member 13, and the other end of the protrusion 14 is connected to the inner wall of the rotating member 11. The protrusion 14 protrudes towards the rotating member 11. There are at least two protrusions 14. Two adjacent protrusions 14 are symmetrically arranged along the center line of the support member 13. Multiple protrusions 14 can evenly distribute the weight of the rotating member 11, reduce local stress concentration, reduce the risk of structural damage, reduce the contact area between the rotating member 11 and the support member 13, thereby reducing friction, improving the rotation efficiency of the rotating member 11, and reducing energy loss. This makes the device more efficient when working and can also improve the vibration resistance of the rotating member 11, making it more stable when subjected to external impact or vibration.

[0052] In this embodiment, as Figures 2 to 7 As shown, the protective component 2 includes protective parts 21 and fasteners 23. Protective parts 21 are made of galvanized steel plates, and fasteners 23 are expansion bolts. The rotating mechanism 1 is connected to the protective parts 21. There are two protective parts 21, located on opposite side walls of the trap pit 3. The protective parts 21 correspond to the rotating mechanism 1, and their top surfaces are flush with the ground surface, preventing rats from burrowing into the inner walls of the trap pit 3 and improving rat control. The protective parts 21 are connected to the side walls of the trap pit 3 via fasteners 23. Multiple fasteners 23 enhance the connection strength between the protective parts 21 and the side walls of the trap pit 3, effectively withstanding the forces from the rotating mechanism 1 and other external forces, preventing loosening or detachment during use. Furthermore, the fasteners 23 are easy to disassemble and quick to install, allowing for easy and quick installation. Operators only need to insert bolts into pre-drilled holes and tighten them to achieve a stable connection, reducing installation time and labor costs.

[0053] In addition, the protective component 21 can also be selected from other robust, durable and safe devices, and is not limited to the above embodiments, as long as it can achieve robustness, durability and safety.

[0054] In addition, fastener 23 can also be other devices with fixing functions, and is not limited to the above embodiments, as long as it can achieve fixing.

[0055] Furthermore, such as Figure 2As shown, the protective assembly 2 also includes a base plate 24 and parallel first side plates 22 and second side plates 25. The base plate 24 is a channel steel structure, and the first side plates 22 and second side plates 25 are also channel steel structures. The first side plates 22 and second side plates 25 are vertically connected to opposite sides of the base plate 24, i.e., the connection angle between the first side plate 22 and the base plate 24 is 90°, and the connection angle between the second side plate 25 and the base plate 24 is 90°. The rotating mechanism 1 is located between the first side plate 22 and the second side plate 25. The first side plate 22 and the second side plate 25 are both connected to the sidewall of the trap pit 3. Fasteners 23 are provided on the base plate 24, the first side plate 22, and the second side plate 25. The base plate 24, the first side plate 22, and the second side plate 25 are all connected to the side wall of the trap pit 3 through the fasteners 23. Two protective components 21 are attached to the side ends of the base plate 24 and are located on different side ends of the base plate 24. The end faces of the first side plate 22 and the second side plate 25 are flush with the ground. Through the combination of the base plate 24, the first side plate 22, the second side plate 25, and the protective components 21, the protective assembly 2 forms a sturdy frame that can effectively support the rotating mechanism 1 and prevent mice from escaping. The distance between the side of the rotating mechanism 1 near the equipment door and the first side plate 22 is 1 to 5 mm, and can be selected from 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm. This can effectively prevent mice from entering the electrical room or equipment room through the gap, and the rotating mechanism 1 will not collide with the first side plate 22 when rotating. The distance between the side of the rotating mechanism 1 away from the equipment door and the second side plate 25 is 5.5 to 7 cm, which ensures the flexible rotation of the rotating part 11 and can effectively prevent the feet of walking personnel from getting stuck in the trap, thereby improving the safety of personnel.

[0056] In addition, the base plate 24, the first side plate 22, and the second side plate 25 can also be selected from other robust, durable, and safe components, and are not limited to the above embodiments, as long as they can achieve robustness, durability, and safety.

[0057] Furthermore, such as Figure 6 As shown, the protective component 21 is provided with a groove 211. The connecting rod 12 is connected to the protective component 21 through the groove 211. The groove 211 is correspondingly set with the fixing component. The connecting rod 12 is placed in the groove 211. The groove 211 has an arc-shaped structure on the side facing the base layer. The arc design can make the protective component 21 bear the force more evenly, reduce local stress concentration, and improve the overall stability of the structure. This can effectively prevent the protective component 21 from getting stuck in the groove 211 or being unable to be placed smoothly, reduce the error in the installation process, and ensure the accurate positioning of the protective component 21.

The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
