AI Technical Summary
Existing electrical cabinets cannot simultaneously provide rain and snow protection and heat dissipation in open-air environments, resulting in increased cabinet size and reduced heat dissipation efficiency.
A fan, rain shield, opening and closing mechanism, detection mechanism, and limit mechanism are installed on the top of the electrical cabinet. The rain and snow sensor detects the weather conditions and controls the opening and closing of the rain shield to achieve rain and snow protection while maintaining the heat dissipation effect of the electrical cabinet.
It achieves rain and snow protection without changing the size of the electrical cabinet, and improves heat dissipation efficiency through fan cooling to prevent rain and snow from entering and affecting heat dissipation.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rainproof equipment for electrical cabinets, specifically a heat dissipation device for electrical cabinets with rain and snow protection function. Background Technology
[0002] Electrical cabinets are mostly made of steel and are used to protect components. They are primarily used in the chemical, power, industrial, nuclear power, fire safety monitoring, and transportation industries. Due to their usage requirements, they are often placed in open-air environments. Most existing electrical cabinets with relatively good rain protection use rain covers, but this increases the cabinet's size, making it inconvenient to place multiple cabinets side-by-side. Additionally, these cabinets suffer from reduced heat dissipation. Utility Model Content
[0003] The technical problem to be solved by this utility model application is to provide an electrical cabinet heat dissipation device that has rain and snow protection function, while not affecting the installation and heat dissipation function of the electrical cabinet.
[0004] To solve the above problems, this application provides the following technical solution:
[0005] An electrical cabinet heat dissipation device with rain and snow protection function includes a fan, a rain shield, an opening and closing component, a detection component, and a limiting component; the fan is installed in a pre-opening on the top of the electrical cabinet body, the rain shield is slidably suspended above the fan by the limiting component, the opening and closing component can adjust the position of the rain shield, and the detection component has the function of detecting rain and snow and controlling the opening and closing component.
[0006] Preferably, the rain shield can be closed and cover the fan during rain or snow.
[0007] Preferably, the opening and closing assembly includes a transmission block, a lead screw, and a drive motor.
[0008] Preferably, the detection components include a rain / snow sensor and a controller.
[0009] Preferably, the limiting component includes a limiting block, a limiting rod, and a mounting block.
[0010] This application has the following advantages compared with the prior art:
[0011] This device is installed on top of the existing electrical cabinet, which not only provides rain and snow protection but also maintains the original cabinet's size, facilitating placement between cabinets. Furthermore, the fan-based cooling system allows for efficient expulsion of hot air accumulated at the top of the cabinet, resulting in better heat dissipation. Attached Figure Description

[0017] refer to Figures 1-4 This application provides a heat dissipation device for an electrical cabinet with rain and snow protection, including a fan 2, a rain shield 3, an opening and closing assembly 4, a detection assembly 5, and a limiting assembly 6. The fan 2 is installed in a pre-opening 11 at the top of the electrical cabinet body 1. The rain shield 3 is slidably suspended above the fan 2 by the limiting assembly 6. The opening and closing assembly 4 can adjust the position of the rain shield 3. The detection assembly 5 has the function of detecting rain and snow and controlling the opening and closing assembly 4.
[0018] Specifically, the rain shield 3 can be closed and cover the fan 2 in rainy or snowy weather.
[0019] Specifically, the opening and closing assembly 4 includes a transmission block 41, a lead screw 42, and a drive motor 43.
[0020] Specifically, the detection component 5 includes a rain and snow sensor 51 and a controller 52.
[0021] Specifically, the limiting component 6 includes a limiting block 61, a limiting rod 62, and a mounting block 63.
[0022] Working principle: An opening 11 is designed on the top of the electrical cabinet that requires rain protection, and this device is installed. When used in sunny weather, the rain shield 3 does not cover the fan 2, which facilitates the dissipation of heat inside the electrical cabinet body 1. In rainy or snowy weather, the rain and snow sensor 51 detects and sends a signal to the controller 52. The controller 52 then controls the drive motor 43 to work, causing the lead screw 42 to rotate and push the rain shield 3 above the fan 2. Since there is a certain distance between the two, rain and snow do not enter the electrical cabinet while heat dissipation is still possible. When the weather is sunny, the rain shield 3 is moved away from the fan 2 to allow the space above the fan 2 to be clear and accelerate heat dissipation. The protective shell 7 is used to protect the drive motor 43 and increase its service life.
