Description

Technical Field

[0001] This utility model relates to the technical field of power distribution cabinet components, specifically a box-type power distribution cabinet top cover component. Background Technology

[0002] The top cover assembly is a key part of the distribution cabinet's outer shell structure. Its main functions include protection, preventing rainwater, dust, foreign objects, etc. from entering the cabinet, achieving an IP54 or higher protection rating, reducing the operating temperature of internal equipment through natural or forced ventilation design, and providing overall strength and stability to the cabinet to resist wind pressure and external impacts.

[0003] First, if there is no forced ventilation in the device, the distribution cabinet can only rely on natural convection for heat dissipation, resulting in poor heat dissipation and easy overheating or even damage to the equipment. Furthermore, under high load or high temperature conditions, the internal temperature of the distribution cabinet will rise, which can easily lead to overheating of electrical equipment and failure of components, thereby affecting the overall system stability.

[0004] Secondly, without the ability to quickly install and coordinate, the power distribution cabinet can only meet basic power distribution needs and cannot easily add new functions (such as monitoring, environmental monitoring, communication, etc.).

[0005] Finally, if the protective function is not adequate, rainwater may enter the cabinet, causing electrical short circuits or equipment damage, or even a fire. Furthermore, debris, dust, plant remains, and other contaminants entering the cabinet may cause equipment blockage, poor heat dissipation, or even affect equipment operation.

[0020] 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.

[0021] Example 1: Please see Figures 1-5 A box-type power distribution cabinet top cover assembly includes a main body 1, a ventilation mechanism, a connecting mechanism, and a rainproof mechanism. The ventilation mechanism includes a mounting component 2 and a fan 3. The fan 3 is fixedly installed in the mounting component 2. The mounting component 2 is connected to the main body 1. A locking block 4 and a spring 5 are installed on the mounting component 2. The locking block 4 is slidably connected to the mounting component 2 and is connected to the main body 1. One end of the spring 5 is fixedly connected to the locking block 4. The connecting mechanism includes a rotating rod 6 and a telescopic rod 7. The rotating rod 6 is installed inside the main body 1 and is rotatably connected to the main body 1 and is connected to the telescopic rod 7. The telescopic rod 7 is slidably connected to the main body 1.

[0022] In this embodiment, the ventilation mechanism includes a mounting component 2 and a fan 3. In use, the fan 3 is first fixedly installed in the mounting component 2. Then, the mounting component 2 can be installed into the mounting groove 11 of the main body 1. When installing the mounting component 2, the locking block 4 is pulled first so that the locking block 4 can directly compress the spring 5. During this process, the positioning rod 13 on the mounting component 2 is directly connected to the positioning hole 12 on the main body 1. After the mounting component 2 is installed into the mounting groove 11, the locking block 4 can be released directly. Under the action of the compressed spring 5, the locking block 4 is pushed directly into the locking hole 14, thereby fixing the mounting component 2 in the mounting groove 11.

[0023] In this embodiment, the connecting mechanism includes a rotating rod 6 and a telescopic rod 7. In use, when the main body 1 is installed on the power distribution cabinet, the rotating rod 6 installed inside the main body 1 can be rotated directly, so that the threaded hole 16 on the rotating rod 6 engages with the threaded telescopic rod 7, thereby allowing the telescopic rod 7 to slide inside the main body 1. Moreover, under the cooperation of the limiting block 18 and the limiting groove 17, the telescopic rod 7 can slide stably and connect with the power distribution cabinet, and the sealing gasket 19 also fits tightly against the power distribution cabinet.

[0024] In this embodiment, the rainproof mechanism includes a rim 8 and a baffle plate 9. In use, the baffle plate 9 is first installed on the main body 1. At this time, the fitting block 21 on the baffle plate 9 is directly installed into the fitting groove 20 of the main body 1 and is directly magnetically connected to the magnetic block 10 on the fitting groove 20. Then, the rim 8 can be installed on the main body 1 so that when rainwater drips, it does not approach the protective plate. When the fan 3 is running, it needs to draw air from the outside through the flow hole. At this time, the baffle plate 9 prevents all debris from entering the main body 1.

[0025] Example 2: In summary, during use, first assemble the main body 1, fix the fan 3 in the mounting part 2, and then install the mounting part 2 into the mounting groove 11 of the main body 1. When installing the mounting part 2, first pull the locking block 4 so that the locking block 4 can directly compress the spring 5. During this process, the positioning rod 13 on the mounting part 2 directly engages with the positioning hole 12 on the main body 1. After the mounting part 2 is installed into the mounting groove 11, the locking block 4 can be released directly. Under the action of the compressed spring 5, the locking block 4 is pushed directly into the locking hole 14, thereby fixing the mounting part 2 in the mounting groove 11. Then assemble the remaining components on the main body 1 and install the baffle plate 9 onto the main body 1. At this time, the fitting block 21 on the baffle plate 9 directly... The device is installed into the fitting groove 20 of the main body 1 and directly magnetically connected to the magnetic block 10 on the fitting groove 20. Then, the rim 8 can be installed on the main body 1 so that when rainwater drips, it does not approach the protective plate. When the fan 3 is running, it needs to draw air from the outside through the flow hole. At this time, the baffle plate 9 prevents all debris from entering the main body 1. When the main body 1 is installed on the distribution cabinet, the rotating rod 6 installed inside the main body 1 can be rotated directly so that the threaded hole 16 on the rotating rod 6 engages with the threaded extension rod 7, so that the extension rod 7 can slide inside the main body 1. Moreover, with the cooperation of the limiting block 18 and the limiting groove 17, the extension rod 7 can slide stably and connect with the distribution cabinet. The sealing gasket 19 also fits tightly against the distribution cabinet.

[0026] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
