Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a heat dissipation switch cabinet. Background Art

[0002] Switchgear is an electrical equipment mainly used for power generation, transmission, distribution and energy conversion in power systems. Its main function is to open, close, control and protect electrical equipment. The components in the switchgear mainly include circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protective devices. The heat dissipation performance of current switchgear is generally not very good, and some current switchgears usually have filters at the heat dissipation holes to prevent mosquitoes or flocs in the external environment, such as poplar and willow catkins, from entering the cabinet. However, the filters are generally fixed to the cabinet by screws. When the mesh of the filter is blocked, it is not convenient to disassemble it for cleaning. In addition, the current switchgear has poor shock absorption performance. When it is vibrated during transportation, it is easy to be damaged. Therefore, we propose a heat dissipation switchgear to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a heat dissipation switch cabinet proposed in an embodiment of the utility model includes a cabinet 1, and circular vents 2 are opened on both side walls of the cabinet 1, and the two vents 2 are arranged up and down. A fan 3 is fixed on the inner wall of one side of the cabinet 1 and located at the vent 2. Threaded connecting pipes 4 are fixed on both side walls of the cabinet 1 at the vent 2. The surfaces of the threaded connecting pipes 4 are threadedly connected with threaded sleeves 5, and one end of the threaded sleeves 5 is fixed with a filter screen 6. A shock absorbing component 7 is arranged at the bottom of the cabinet 1, and a cabinet door 8 is hinged on the front of the cabinet 1 through a hinge. It should be noted that a lock buckle is installed on the cabinet door 8, and a lock ring is installed on the cabinet 1, but it is not shown in the drawings of the specification. This is an existing known technology. A PLC controller 9 and The temperature sensor 10 and the PLC controller 9 are electrically connected to the temperature sensor 10 and the fan 3. When the internal temperature of the cabinet 1 is high, the temperature sensor 10 will send a signal to the PLC controller 9, and the PLC controller 9 will control the fan 3 to start, thereby accelerating the air flow rate inside the cabinet 1, so that a better heat dissipation effect can be achieved. By setting a filter 6 at the vent 2, mosquitoes or flocs in the external environment, such as poplar and willow catkins, can be prevented from entering the interior of the cabinet 1, thereby providing better protection for the electrical components inside the cabinet 1. By setting the shock-absorbing component 7, when encountering vibration during transportation, a better shock-absorbing effect can be achieved, thereby providing better protection for the electrical components inside the cabinet 1.

[0025] like Figure 5 and Figure 6As shown, in some embodiments, the shock absorbing assembly 7 includes a connecting block 701 fixed to the bottom of the cabinet 1, a base 702 is provided below the cabinet 1, the connecting block 701 is slidably connected in the base 702, both side walls of the connecting block 701 are fixed with limiting blocks 705, and both side inner walls of the base 702 are provided with limiting grooves 706 adapted to the limiting blocks 705, so that the connecting block 701 can slide more stably in the base 702, and the four corners of the bottom of the connecting block 701 are fixed with springs 7 03. The bottom ends of the springs 703 are fixedly connected to the bottom inner wall of the base 702. Damping telescopic rods 704 are fixed to the four corners of the top of the base 702. The top ends of the damping telescopic rods 704 are fixedly connected to the bottom of the cabinet 1. During transportation, when vibrations occur, when the cabinet 1 drives the connecting block 701 to move downward, the spring 703 and the damping telescopic rod 704 will be compressed. Under the joint action of the spring 703 and the damping telescopic rod 704, the cabinet 1 can have a better shock-absorbing and buffering effect.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, universal self-locking wheels 707 are installed at the four bottom corners of the base 702 to facilitate movement. The area of ​​the filter 6 is larger than the area of ​​the vent 2 so that the vent 2 can be completely covered. The surface of the threaded sleeve 5 is provided with anti-slip textures, which can play a better anti-slip role, thereby facilitating the user to rotate the threaded sleeve 5.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
