Description

TECHNICAL FIELD

[0001] The utility model relates to a power distribution cabinet technical field, specifically is a power distribution cabinet heat abstractor. BACKGROUND

[0002] The power distribution cabinet is the switchgear, measurement instrument, protection electric appliance and auxiliary equipment assembly in the closed or semi-closed metal cabinet or screen according to the electrical wiring requirement, constitutes the low voltage distribution box. Normal operation can be assisted by hand or automatic switch to connect or break the circuit. When the fault or abnormal operation, the protection electric appliance is used to cut off the circuit or alarm. The measurement instrument can display various parameters in the operation, and also can adjust some electrical parameters, prompt or send the signal to the deviation of normal working state.

[0003] When the heat dissipation fan is used for a long time to dissipate heat for the power distribution cabinet, a large amount of dust is usually adhered to the protective cover of the heat dissipation fan, which affects the heat dissipation effect of the power distribution cabinet, and the protective cover on the heat dissipation fan needs to be cleaned. However, there are usually two ways to clean the protective cover at present. One is to directly scrub the protective cover on the heat dissipation fan. Since the space inside the power distribution cabinet is relatively small, it is not convenient to scrub, and it is difficult to clean thoroughly. Since there are a large number of electrical components inside the power distribution cabinet, there is a risk of electric shock, which poses a certain safety hazard. The second way is to disassemble the protective cover on the heat dissipation fan for cleaning. Although this cleaning method can overcome the above defects, since the protective cover and the heat dissipation cover are connected by bolts, it is not convenient to disassemble.

[0004] Therefore, we propose a power distribution cabinet heat abstractor to solve the problems mentioned above. CONTENT OF THE UTILITY MODEL

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art belong to the range of protection of the utility model.

[0020] Embodiments of the utility model:

[0021] Embodiment one

[0022] A kind of heat dissipation device for switch board, including heat dissipation cover 1, fan 2 is installed in the inside of heat dissipation cover 1, and the output shaft of fan 2 is installed with heat dissipation vane 3, by the cooperation of fan 2 and heat dissipation vane 3, the inside of switch board (not shown in drawing) can be heat dissipated, avoid the phenomenon that electrical component is damaged due to the temperature in switch board is too high, to improve the stability of switch board.

[0023] Specifically speaking: heat dissipation vane 3 includes rotating disc 31 that is screw mounted on the output shaft of fan 2, and a plurality of fan blades 32 are screw mounted on rotating disc 31, so that the fan blades 32 can be removed from fan 2, facilitating cleaning of fan blades 32.

[0024] Both ends of heat dissipation cover 1 are provided with openings, one of which is an air inlet, and the other is an air outlet, which can ensure that external air flows into the heat dissipation cover 1; it should be noted that each opening is symmetrically provided with a mounting bracket 4 similar to a "U" shape, and a protective cover 5 is mounted between the two mounting brackets 4. The protective cover 5 is provided to protect against accidental contact with the fan blades and to improve the safety of the workers.

[0025] It should be noted that one side of the protective cover 5 is provided with a limiting assembly 6, one end of the two mounting brackets 4 is provided with a limiting plate 8 cooperating with the limiting assembly 6, and the limiting assembly 6 and the limiting plate 8 are provided to limit the protective cover 5, preventing the protective cover 5 from shaking during use. The other side of the protective cover 5 is provided with a clamping plate 7, and the heat dissipation cover 1 is also provided with a clamping assembly 9. The clamping plate 7 and the clamping assembly 9 cooperate to quickly install and disassemble the protective cover 5, facilitating subsequent cleaning of the protective cover 5 and providing convenience for the workers;

[0026] Specifically speaking: the limiting assembly 6 includes a protrusion 61 fixed to one side of the protective cover 5, limiting shafts 62 are fixed to both sides of the protrusion 61, and the limiting shafts 62 can be inserted below the limiting plate 8, thereby limiting the protective cover 5;

[0027] Specifically, the locking assembly 9 includes a locking box 91 fixed on the heat dissipation cover 1 and a locking member 92 located on one side of the locking box 91. It should be noted that a slope 96 in the shape of an "arc" is provided on one side of the locking member 92, so that when the locking plate 7 squeezes the slope 96, the slope 96 can move horizontally; two parallel pressure rods 93 are fixed on one side of the locking member 92, and one end of the pressure rod 93 is slidably installed inside the locking box 91, and a pressure plate 94 is also fixed on the pressure rod 93.

If the protective cover 5 is rotated out from between the two mounting brackets 4, the protective cover 5 can be taken out, thereby completing the work of disassembling the protective cover 5, and then the protective cover 5 can be subsequently rinsed.

[0030] The pressure plate 94 can drive the clamping member 92 to move through the pressure rod 93, and the clamping plate 7 can be clamped by the clamping member 92 to prevent the protective cover from shaking during use.
