Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment protection technology, and specifically refers to a protective device for a distribution box. Background Technology

[0002] Distribution boxes are devices in power systems used to centrally install switches, meters, protective electrical appliances, and other equipment. They are widely used in industrial, commercial, and residential power supply locations, serving the functions of power distribution, circuit control, and safety protection. In outdoor environments, distribution boxes are often exposed to external factors such as rain, sunlight, and dust. Long-term exposure to moisture or direct sunlight can lead to corrosion of internal components, decreased insulation performance, and even short-circuit faults. Therefore, reliable protective devices are needed to ensure their safe operation.

[0003] Currently, common protective devices for distribution boxes are mostly fixed rain shelters or simple baffles, which have limited protective range, only able to block rain or sunlight from a single direction, and cannot be flexibly adjusted according to actual needs. For example, some rain shelters only cover the top of the distribution box, making it difficult to block oblique wind and rain; while side baffles are mostly fixed installations, unable to be quickly expanded or retracted when needed, resulting in poor protective effect. In addition, existing protective devices are mostly installed using bolt fastening or welding methods, which are inconvenient to disassemble and difficult to adapt to the protection needs of different environments. Therefore, there is an urgent need for a scalable, multi-directional distribution box protective device that can quickly switch protective states to improve the environmental adaptability and safety of distribution boxes. Utility Model Content

[0004] This utility model uses a sliding and expandable main protective plate and side protective plate in conjunction with a magnetic locking and limiting mechanism to achieve adjustable switching of the protection range of the distribution box and flexible protection from multiple directions, thereby alleviating the problems mentioned in the background art.

[0005] The purpose of this utility model is achieved as follows: a protective device for a distribution box, comprising:

[0006] An expandable protective assembly includes a main protective plate that slides back and forth along the top of the distribution box and two side protective plates symmetrically disposed below the main protective plate. The main protective plate is connected to the distribution box via a top guide rail, and the side protective plates are slidably connected to the main protective plate via two side guide rails.

[0007] Locking assembly for securing the initial position of the side guard plate;

[0008] Limiting components are used to limit the forward and backward sliding travel of the main protective plate and the lateral expansion travel of the side protective plates;

[0009] The release mechanism includes a grip and a connecting part that is linked to the locking assembly. During operation, the locking state of the side guard plate is released through the connecting part.

[0010] The present invention is further configured such that the main protective plate and the side protective plate are made of glass fiber reinforced polypropylene composite material.

[0011] The present invention is further configured such that the main protective plate is a drainage structure with both sides tilted downwards, and the tilt angle is 8° to 12°.

[0012] The present invention is further configured such that the main protective plate has downwardly extending ear plates on both sides, and the inner side of the ear plates is slidably connected to the side wall of the distribution box.

[0013] The present invention is further configured such that the locking assembly includes an initial base connecting two side guide rails, a magnetic conductive sheet disposed on the initial base, and permanent magnets arranged at intervals on the side protective plate and magnetically connected to the magnetic conductive sheet.

[0014] The present invention is further configured such that the main protective plate is connected to the top guide rail of the distribution box, and the ear plate is connected to the side wall of the distribution box via pulley transmission.

[0015] The present invention is further configured such that the limiting component includes:

[0016] The first limiting baffle is located at the top of the side guard plate to limit the maximum extension distance of the side guard plate;

[0017] The second limiting baffle is located at the top of the top guide rail and is arranged at the front and rear ends of the top guide rail respectively.

[0018] The present invention is further configured such that the connecting part of the release device is connected to the bottom of the side protective plate, and the magnetic connection between the side protective plate and the initial base is released by pulling the grip part located below the connecting part.

[0019] By adopting the above technical solution, the beneficial effects that this utility model can achieve are:

[0020] 1. By sliding the main protective plate along the top guide rail and expanding the side protective plate laterally, three working modes can be achieved: forward rain protection, side sunshade, and combined protection, which significantly improves the adjustability of the protection range and environmental adaptability.

[0021] 2. The magnetic locking assembly, composed of a magnetic sheet and a permanent magnet, works in conjunction with a release mechanism that allows for one-button unlocking and quick switching of protection modes by pulling the grip, simplifying the operation process.

[0022] 3. By using pulleys to slide between the ear plate and the side wall of the distribution box, and by using pulleys to drive the top guide rail and the main protective plate, frictional resistance is reduced, ensuring smooth sliding of the main protective plate and improving structural reliability.

[0031] Example 1:

[0032] This embodiment provides a protective device for a distribution box, including:

[0033] The expandable protection component 1 includes a main protection plate 10 that slides back and forth along the top of the distribution box and two side protection plates 11 symmetrically arranged below the main protection plate 10. The main protection plate 10 is connected to the distribution box through a top guide rail 12, and the side protection plates 11 are slidably connected to the main protection plate 10 through two side guide rails 13.

[0034] Locking component 2 is used to fix the initial position of the side guard plate 11;

[0035] Limiting component 3 is used to limit the forward and backward sliding stroke of the main protective plate 10 and the lateral expansion stroke of the side protective plate 11;

[0036] The release device 4 includes a gripping part 40 and a connecting part 41 that is linked to the locking assembly 2. During operation, the locking state of the side guard plate 11 is released through the connecting part 41.

[0037] The Scalable Protection Component 1 provides scalable protection for the distribution box, adapting to different usage scenarios and protection requirements.

[0038] The main protective plate 10 provides top protection for the distribution box and can slide back and forth along the top of the distribution box to adapt to different protection requirements. The main protective plate 10 is a plate-like structure that slopes downward on both sides, similar to a sloping roof shape. It is located on the top of the distribution box and is connected to the distribution box via the top guide rail 12.

[0039] The side protective plates 11 are symmetrically arranged below the main protective plate 10 and can be extended laterally, providing multi-directional protection for the distribution box together with the main protective plate 10. The side protective plates 11 are usually rectangular plate structures, located below the main protective plate 10, and are slidably connected to the main protective plate 10 through two lateral guide rails 13.

[0040] The top guide rail 12 provides a sliding track for the main protective plate 10, allowing it to move back and forth along the top of the distribution box. The top guide rail 12 is typically a long, narrow track structure that can be fixed to the top of the distribution box by welding or bolts.

[0041] The side guide rail 13 provides a sliding track for the side protective plate 11, allowing the side protective plate 11 to expand laterally relative to the main protective plate 10. Similar to the top guide rail 12, the side guide rail 13 is a long, narrow track structure, with one end connected to the main protective plate 10 and the other end connected to the side protective plate 11. The side guide rail 13 can be fixed to the bottom of the main protective plate 10 by welding or bolts, and can be slidably connected to the side protective plate 11 via a guide rail block structure.

[0042] The locking component 2 is responsible for fixing the initial position of the side guard plate 11, preventing it from sliding freely when the release device 4 is not operated, and ensuring that the protective device is structurally stable and the position of the side guard plate 11 is fixed under normal use.

[0043] The limiting component 3 is used to limit the forward and backward sliding stroke of the main protective plate 10 and the lateral expansion stroke of the side protective plate 11.

[0044] The release device 4 is used to release the locked state of the side guard plate 11, thereby expanding the side guard plate 11. The release device 4 includes a gripping part 40 and a connecting part 41 that is linked to the locking assembly 2.

[0045] Example 2:

[0046] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] The main protective plate 10 and the side protective plate 11 are made of glass fiber reinforced polypropylene composite material.

[0048] In this embodiment, glass fiber reinforced polypropylene composite material is used to manufacture the main protective plate 10 and the side protective plate 11. The main purpose is to comprehensively utilize the various excellent properties of this material to improve the performance of the distribution box protection device. Glass fiber reinforced polypropylene composite material is lightweight, facilitating the installation and operation of the protection device, while reducing the pressure on the distribution box from the overall device. Its good weather resistance can resist the effects of external environmental factors such as sunlight exposure and wind and rain erosion, ensuring that the protection device is not prone to aging or damage during long-term use, thus extending its service life. Its excellent insulation properties can effectively prevent leakage accidents, ensuring the safety of the distribution box and its surrounding environment, and providing reliable protection for the distribution box.

[0049] Example 3:

[0050] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0051] The main protective plate 10 is a drainage structure that slopes downwards on both sides, with an inclination angle of 8° to 12°.

[0052] In this embodiment, the main protective plate 10 is designed as a drainage structure with both sides sloping downwards, and the tilt angle is set between 8° and 12°, which is of great significance. This tilt angle can effectively guide rainwater to flow quickly down from both sides of the main protective plate 10, preventing water from accumulating on the protective plate. Accumulated water can not only increase the load on the protective plate, but may also seep into the distribution box, damaging the internal electrical components. The appropriate tilt angle ensures efficient drainage, balancing the stability of the protective plate structure with the realization of the drainage function. While protecting the top of the distribution box from rainwater intrusion, it extends the service life of the protective device and the distribution box, ensuring the normal operation of the distribution box.

[0053] Example 4:

[0054] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] The main protective plate 10 has downwardly extending ear plates 5 on both sides, and the inner side of the ear plates 5 is slidably connected to the side wall of the distribution box.

[0056] The ear plate 5 serves to assist the main protective plate 10 in stable sliding and enhance the connection stability between the protective device and the distribution box. The ear plate 5 is a plate-like structure extending downwards from both sides of the main protective plate 10. Its shape is adapted to the main protective plate 10 and the side wall of the distribution box. Openings can be formed on the ear plate 5 to allow the side protective plates 11 to pass through. The inner side of the ear plate 5 is slidably connected to the side wall of the distribution box through a specific sliding structure. A common method is to provide a groove or slider on the inner side of the ear plate 5, which cooperates with the corresponding slider or groove on the side wall of the distribution box to achieve smooth sliding. The ear plate 5 and the main protective plate 10 can be integrally molded to ensure their coordinated operation.

[0057] Under the constraint and guidance of the top guide rail 12, the main protective plate 10 can slide back and forth. In this embodiment, the ear plate 5 serves as a connection and transmission component between the main protective plate 10 and the side wall of the distribution box. During the sliding process of the main protective plate 10, its sliding connection structure with the side wall of the distribution box provides guidance and stable support for the sliding of the main protective plate 10. When the main protective plate 10 is subjected to force and slides, the ear plate 5 moves synchronously. The friction and sliding resistance between the ear plate 5 and the side wall of the distribution box interact to ensure that the sliding of the main protective plate 10 is smooth and controllable. At the same time, due to the integrated structure of the ear plate 5 and the main protective plate 10, the ear plate 5 can transfer part of the force borne by the main protective plate 10 to the side wall of the distribution box, dispersing the force on the main protective plate 10 and enhancing the stability of the entire protective device.

[0058] Example 5:

[0059] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0060] The locking assembly 2 includes an initial base 20 connecting two side guide rails 13, a magnetic conductive sheet 21 disposed on the initial base 20, and permanent magnets 22 arranged at intervals on the side protective plate 11 and magnetically connected to the magnetic conductive sheet 21.

[0061] The initial base 20 serves as the basic support structure for the locking assembly 2, connecting the two side guide rails 13, providing an installation position for the magnetic plate 21, and indirectly establishing an association with the side protective plate 11 through its connection with the side guide rails 13, thereby achieving locking control of the side protective plate 11. The initial base 20 is typically a rectangular plate structure located between the two side guide rails 13, with both ends tightly connected to the side guide rails 13. The initial base 20 can be connected to the side guide rails 13 on both sides by welding or bolts.

[0062] The magnetic conductive sheet 21 is used to conduct the magnetic field, enhancing the magnetic attraction between the permanent magnet 22 and the initial base 20, thereby achieving reliable locking of the side protective plate 11. The magnetic conductive sheet 21 is generally a thin sheet structure with a smooth, flat surface to ensure good contact with the initial base 20 and the permanent magnet 22. Its shape is usually rectangular or square to ensure it covers the area on the initial base 20 corresponding to the permanent magnet 22, achieving optimal magnetic conduction. The magnetic conductive sheet 21 can be fixed to the side of the initial base 20 facing the side protective plate 11 by adhesive or screws.

[0063] The permanent magnet 22 locks the side protective plate 11 through magnetic attraction. Simultaneously, under the action of the release device 4, it can separate from the magnetic sheet 21, releasing the lock on the side protective plate 11 and allowing it to be extended. The permanent magnet 22 is typically a block or sheet structure, composed of magnetic material, and commonly appears as a cuboid block or thin rectangular sheet, spaced apart on the side of the side protective plate 11 facing the initial base 20 to ensure uniform locking force along the entire length of the side protective plate 11. Similar to the magnetic sheet 21, the permanent magnet 22 can be installed on the side protective plate 11 by adhesive, screw fixing, or slot embedding.

[0064] The locking assembly 2 utilizes the magnetism of the permanent magnet 22, enhanced by the magnetic field effect of the magnetic conductive sheet 21, to attract the side protective plate 11 onto the initial base 20, thus locking the side protective plate 11. When it is necessary to expand the side protective plate 11, the release device 4 is operated. The release device 4 applies an external force to the side protective plate 11 through the connecting part 41. This external force overcomes the magnetic attraction between the permanent magnet 22 and the magnetic conductive sheet 21, causing the permanent magnet 22 to separate from the magnetic conductive sheet 21, thereby releasing the locked state of the side protective plate 11. The side protective plate 11 can then slide and expand under the guidance of the side guide rail 13. Throughout the process, the initial base 20, as the structure connecting the side guide rail 13 and supporting the magnetic conductive sheet 21, ensures the stability and reliability of the locking assembly 2.

[0065] Example 6:

[0066] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0067] The main protective plate 10 is connected to the top guide rail 12 of the distribution box, and the ear plate 5 is connected to the side wall of the distribution box via pulleys 6.

[0068] In this embodiment, pulley 6 is used to drive the connection between the main protective plate 10 and the top guide rail 12 of the distribution box, as well as the ear plate 5 and the side wall of the distribution box. The main purposes are as follows.

[0069] The pulley 6 drive connection between the main protective plate 10 and the top guide rail 12 of the distribution box allows the main protective plate 10 to slide smoothly along the guide rail, making it easy to flexibly adjust the position of the main protective plate 10 as needed, so as to protect or expose specific parts of the distribution box, making the operation more convenient and labor-saving. At the same time, the pulley 6 drive can reduce friction, reduce energy loss, and extend the service life of related components.

[0070] The ear plate 5 is connected to the side wall of the distribution box via pulley 6, which helps the ear plate 5 to move stably on the side wall of the distribution box. On the one hand, it can better adapt to the movement of the main protective plate 10 and work together. On the other hand, it can also enhance the stability and reliability of the entire protective structure, ensuring that the ear plate 5 can play an auxiliary support and positioning role during the movement of the protective plate, making the protective system more stable, thereby better protecting the distribution box and its internal equipment.

[0071] Example 7:

[0072] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0073] The limiting component 3 includes:

[0074] The first limiting baffle 30 is provided on the top of the side guard plate 11 to limit the maximum expansion distance of the side guard plate 11;

[0075] The second limiting baffle 31 is located on the top of the top guide rail 12 and is arranged at the front and rear ends of the top guide rail 12 respectively.

[0076] The first limiting baffle 30 is specifically designed to limit the maximum extension distance of the side guard plate 11, preventing it from sliding excessively on the lateral guide rail 13 and detaching from the rail or colliding with other components, thus ensuring that the side guard plate 11 operates within a safe extension range. The first limiting baffle 30 is generally a rectangular plate structure, its dimensions fully covering the extension path of the side guard plate 11, effectively blocking it. The first limiting baffle 30 can be installed on top of the side guard plate 11 by welding or bolts, and is perpendicularly fixed to the upper surface of the side guard plate 11.

[0077] The second limiting baffle 31 restricts the forward and backward sliding stroke of the main protective plate 10 on the top guide rail 12, preventing the main protective plate 10 from sliding off the guide rail or excessively sliding and causing the protective device to become unbalanced, ensuring that the sliding of the main protective plate 10 is within a safe and controllable range. The second limiting baffle 31 is also a plate-shaped or block-shaped structure, commonly a rectangular block or plate, whose size and shape are adapted to the ends of the top guide rail 12, and can be tightly installed at both ends of the top guide rail 12, effectively preventing excessive sliding of the main protective plate 10. The second limiting baffle 31 can be installed at both ends of the top of the top guide rail 12 by welding or bolts, and is vertically fixed to the upper surface of the top guide rail 12, located on the path of the main protective plate 10's forward and backward sliding.

[0078] Example 8:

[0079] This embodiment provides a protective device for a distribution box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0080] The connecting part 41 of the release device 4 is connected to the bottom of the side protective plate 11. By pulling the grip part 40 located below the connecting part 41, the magnetic connection between the side protective plate 11 and the initial base 20 is released.

[0081] The purpose of this design is to provide users with a convenient, efficient, and easy-to-operate way to unlock the side protective plate 11. The connecting part 41 is connected to the bottom of the side protective plate 11, ensuring that the action of pulling the grip 40 is accurately transmitted to the magnetic connection part 41 between the side protective plate 11 and the initial base 20. Positioning the grip 40 below the connecting part 41 is ergonomically designed, allowing users to naturally grip and apply force. When it is necessary to expand the side protective plate 11, the user only needs to easily pull the grip 40 to overcome the magnetic attraction between the side protective plate 11 and the initial base 20, unlocking it and allowing the side protective plate 11 to slide freely. This greatly improves the convenience and practicality of operating the distribution box protection device, meeting the need for flexible adjustment of the protection range in different scenarios.

[0082] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
