A sealing door is hinged to one side of the housing, a drying mesh box is installed inside the housing, and a placement box is installed inside the drying mesh box. A transparent plate is installed on one side of the placement box, and the sealing door has an installation hole at the position of the transparent plate. A base is installed at the bottom of the housing, and a drying mesh and a dustproof mesh are installed inside the base. Placing the placement box inside the drying mesh box facilitates the placement and removal of the desiccant. The transparent plate allows for easy observation of the distance of the desiccant placed inside the housing, facilitating the replacement of the desiccant at any time.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, the exhaust fan installed on the top achieves rapid heat dissipation inside the cabinet. However, the installation location of this exhaust fan makes disassembly, repair, and maintenance very troublesome if it malfunctions. It may also cause unnecessary damage to other components of the distribution cabinet due to improper operation. Therefore, it is necessary to provide a new type of GGD distribution cabinet to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of GGD distribution cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A new type of GGD distribution cabinet includes: The cabinet has an exhaust vent at the top and symmetrically distributed slide rails at the top of the inner wall of the cabinet. Slider blocks are slidably installed on both slide rails. A support frame is fixedly installed between the bottoms of the two slider blocks. A fan is installed on the support frame. Fixing plates are fixedly installed on both sides of the support frame. The bottom of the fixed plate is provided with a handle, and the top of the handle is fixedly installed with symmetrically distributed limiting posts, which penetrate the fixed plate and extend to the top of the fixed plate. An annular baffle is fixedly installed on the upper side of the outer wall of the limiting post. A spring is sleeved on the outer wall of the limiting post between the annular baffle and the fixing plate. The top of the inner wall of the cabinet is provided with a limiting groove corresponding to the position and number of the limiting posts, and the limiting groove is engaged with the limiting post.

[0007] Preferably, the cabinet has several mounting brackets inside, and positioning blocks are fixedly installed on the front side of both ends of the mounting brackets.

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.

[0020] Please see Figures 1-4 One embodiment provided by this utility model: A new type of GGD distribution cabinet includes: Cabinet 1, with an exhaust vent 9 on the top of the cabinet 1, and symmetrically distributed slide rails 12 on the top of the inner wall of the cabinet 1. Sliding sliders 14 are slidably installed on both slide rails 12, and a support frame 8 is fixedly installed between the bottoms of the two sliding sliders 14. A fan 10 is installed on the support frame 8, and a fixing plate 19 is fixedly installed on both sides of the support frame 8. A handle 15 is provided at the bottom of the fixed plate 19, and symmetrically distributed limiting posts 17 are fixedly installed at the top of the handle 15. The limiting posts 17 penetrate the fixed plate 19 and extend to the top of the fixed plate 19. An annular baffle 16 is fixedly installed on the upper side of the outer wall of the limiting post 17. A spring 18 is sleeved on the outer wall of the limiting post 17 between the annular baffle 16 and the fixing plate 19. The top of the inner wall of the cabinet 1 is provided with a limiting groove 20 corresponding to the position and number of the limiting post 17, and the limiting groove 20 is engaged with the limiting post 17.

[0021] The cabinet 1 has several mounting brackets 3 inside. Positioning blocks 7 are fixedly installed on the front side of both ends of the mounting brackets 3. Positioning bolts 6 are threadedly connected to the positioning blocks 7 through the threaded holes on them. Several mounting grooves 5 are opened on both sides of the inner wall of the cabinet 1, and the mounting grooves 5 are compatible with the positioning bolts 6.

[0022] In one embodiment, ventilation openings 2 are provided on the lower sides of both sides of the cabinet 1 to facilitate air circulation and heat dissipation. A temperature sensor 4 is fixedly installed on the upper side of one side of the cabinet 1 to monitor the temperature inside the cabinet in real time so as to adjust it in a timely manner.

[0023] In one preferred embodiment, a filter screen 13 is fixedly installed inside the exhaust vent 9 to prevent dust and debris from entering the cabinet 1, and several through slots 11 are provided at the bottom of the support frame 8 to facilitate airflow and enhance heat dissipation.

[0024] In one embodiment, the slider 14 is T-shaped and is adapted to the slide rail 12 to prevent the slider 14 from coming off the slide rail 12, ensuring stability when the support frame 8 drives the fan 10 to move, and facilitating quick disassembly of the fan 10.

[0025] In one preferred embodiment, the fixing plate 19 has sliding holes corresponding to the position and number of the limiting posts 17, and the fixing plate 19 is slidably connected to the limiting posts 17 through the sliding holes, which can ensure the stability of the linear sliding of the limiting posts 17 and ensure that they are accurately engaged and disengaged from the limiting groove 20.

[0026] The working principle of this utility model is as follows: All electrical components mentioned in this application are externally connected to a power supply and control switch during use. Parts not mentioned in this device are the same as or can be implemented using existing technology. In the actual operation of the distribution cabinet, the temperature sensor 4 continuously monitors the internal temperature of the cabinet 1 in real time. Once the temperature exceeds a preset value, the control system immediately triggers the fan 10 to start. After the fan 10 starts, it quickly discharges the high-temperature airflow inside the cabinet 1 through the exhaust port 9, thereby achieving rapid heat dissipation of the electrical components inside the cabinet 1 and ensuring stable operation of the electrical components in a suitable temperature environment. However, during the long-term operation of the fan 10, malfunctions are inevitable. When maintenance of the fan 10 is required, the operator first opens the cabinet door of the cabinet 1 and then pulls down the two handles 15. The movement of the handles 15 causes the limiting post 17 to slide downwards in the vertical direction. During this process, the limiting post 17 pushes the annular baffle 16 to apply pressure to the spring 18, causing the spring 18 to undergo elastic deformation. As the limiting post 17 continues to move, its engagement with the limiting groove 20 at the top of the inner wall of the cabinet 1 is released, and the limiting effect disappears. At this time, the operator can pull the support frame 8 outward through the handle 15. The movement of the support frame 8 causes the slider 14 to slide synchronously on the slide rail 12, while the fan 10 moves together with the support frame 8. Until the slider 14 is completely disengaged from the slide rail 12, the support frame 8 and the fan 10 can be removed from the top inside the cabinet 1. After completing the inspection and maintenance of the fan 10, the operator performs the installation in reverse order. Finally, under the elastic force generated by the spring 18 restoring its deformation, the limiting post 17 accurately engages inside the limiting groove 20, ensuring the stability and reliability of the fan 10 installation. The installation design of the fan 10 has significant quick-release characteristics. When installing and removing the fan 10, no additional tools are needed, and it can be quickly installed and removed from the top inside the cabinet 1. Furthermore, the quick-release structure is simple in design, convenient and stable in operation, which greatly improves the work efficiency of wind turbine 10 maintenance and repair and has high practicality.
