[0002] High and low voltage switchgear is an integrated electrical equipment that needs to be installed with various switches, circuit breakers and protective devices. Since the various devices and cables inside the high and low voltage switchgear generate heat during operation, a heat dissipation structure is required to dissipate heat.

[0003] However, the heat dissipation structure adopted by the existing high and low voltage switch cabinets is to dissipate heat through cooling fans, usually two of which are needed in a single cabinet, and the two cooling fans use independent drive motors, so there is a problem of high cost of use.

[0004] Therefore, a heat dissipation structure for high and low voltage switch cabinets is proposed. Utility Model Content

[0009] By adopting the above technical solution, the second dustproof net and the first dustproof net are provided to achieve dustproof and breathable effects.

[0010] The utility model is further configured as follows: a mounting seat is fixedly sleeved on the surface of the air duct, and the interior of the mounting seat is threadedly mounted with a connecting seat through screws.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Embodiment 1:

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A heat dissipation structure for a high and low voltage switch cabinet comprises three blowing bins 1 and three dustproof nets 2. The three blowing bins 1 are all provided with fan blades 3. The three blowing bins 1 are also provided with rotating rods 1 4, 2 5 and 3 6 respectively. The interiors of the three fan blades 3 are fixedly sleeved with the rotating rods 1 4, 2 5 and 3 6 respectively. One end of the rotating rod 2 5 is provided with a motor 7. The surface of the rotating rod 1 4 and the surface of the output end of the motor 7 are fixedly sleeved with a pulley 8. The output end of the motor 7 is installed through a coupling and one end of the rotating rod 2 5. The surface of the rotating rod 3 6 and the surface of the output end of the motor 7 are fixedly connected with a pulley 2 9. The two pulleys 1 8 are connected by belt transmission, and the two pulleys 2 9 are connected by belt transmission; the surfaces of the three blowing bins 1 are all threadedly connected with a connecting seat 10, and a duct 11 is provided on one side of the connecting seat 10. The inside of the duct 11 is fixedly sleeved with an iron wire 12; by setting a single A motor 7 drives a pulley 1 8, a pulley 2 9 and a rotating rod 2 5 to rotate, and the pulley 1 8 and the pulley 2 9 respectively transmit the other pulley 1 8 and the pulley 2 9 to rotate through the belt, thereby driving the rotating rod 1 4 and the rotating rod 3 6 to rotate, and the rotating rod 1 4, the rotating rod 2 5 and the rotating rod 3 6 respectively drive the three fan blades 3 to rotate to generate wind to blow into the interior of the high and low voltage switch cabinet. The use of a single motor 7 can reduce the cost of use, and driving the three fan blades 3 to generate wind to blow into the interior of the high and low voltage switch cabinet has a better heat dissipation effect for the high and low voltage switch cabinet than the traditional two separate fans. By setting a connecting seat 10 and the fan blade 3 threaded connection, the connecting seat 10 and the fan blade 3 are connected when in use, and by pulling the air duct 11 and under the action of the iron wire 12 inside the air duct 11, the air duct 11 can be twisted into different angles, so that the equipment inside the high and low voltage switch cabinet can be accurately blown and cooled.

[0029] Furthermore, the inside of the three fan blades 3 are fixedly sleeved with a dustproof net 2 13, and the three dustproof nets 1 2 are embedded in the inner wall of the high and low voltage switch cabinet. The setting of the dustproof net 2 13 and the dustproof net 1 2 plays a role in dustproof and ventilation.

[0030] Furthermore, a mounting seat 14 is fixedly sleeved on the surface of the air duct 11, and the interior of the mounting seat 14 is threadedly mounted with the connecting seat 10 by screws. Through the setting of the mounting seat 14, the mounting seat 14 is installed with screws and the connecting seat 10, and the air duct 11 can be easily disassembled and replaced when the air duct 11 is damaged.

[0031] Furthermore, the interiors of the three blowing chambers 1 are fixedly connected with a connecting plate 15, and one side of the motor 7 is installed with the connecting plate 15. Through the setting of the connecting plate 15, two of the three connecting plates 15 play a role of supporting the rotating rod 1 4 and the rotating rod 3 6 through the cooperation with the bearing, and the other connecting plate 15 plays a role of installing the motor 7 and supporting the motor 7.

[0032] Furthermore, the interiors of the three connecting plates 15 are rotatably connected to the surfaces of the rotating rod 1 4, the rotating rod 3 6 and the output end of the motor 7 through bearings, and the bearing arrangement serves to limit the rotation of the rotating rod 1 4, the rotating rod 3 6 and the output end of the motor 7 at a fixed position.

[0033] Furthermore, the surfaces of the belts connected by the two pulleys 18 and the belts connected by the two pulleys 29 are both provided with connecting grooves 16, and the connecting grooves 16 are opened on the inner walls of the high and low voltage switch cabinets. The connection grooves 16 are provided to facilitate the rotation of the belts, thereby ensuring that the two pulleys 1 8 and the two pulleys 2 9 can be normally transmitted through the belts.

[0034] Brief description of the use process: when in use, the motor 7 is started to drive the pulley 1 8 and the pulley 2 9 on the surface of the gas output end to rotate and the rotating rod 2 5 connected by the coupling to rotate. The pulley 1 8 and the pulley 2 9 will rotate other pulleys 1 8 and pulley 2 9 through the belt transmission. Since the other pulleys 1 8 and the pulley 2 9 are fixedly connected to the rotating rod 1 4 and the rotating rod 3 6 respectively, the rotating rod 1 4 and the rotating rod 3 6 will also rotate. At this time, the rotating rod 1 4, the rotating rod 2 5 and the rotating rod 3 6 all rotate to generate wind. The wind enters the interior of the high and low voltage switch cabinets, blows the heat inside the high and low voltage switch cabinets through three dustproof nets 1 2 to discharge the interior of the high and low voltage switch cabinets;

[0035] For devices that generate high heat, a connection seat 10 can be threadedly connected to any one of the three blowing chambers 1, so that the wind generated by the fan blades 3 enters the interior of the air duct 11. By twisting the air duct 11, since the interior of the air duct 11 can be twisted and deformed, and the iron wire 12 can be limited after deformation, the air outlet end of the air duct 11 is twisted and aligned with the device that generates high heat, thereby accurately dissipating heat;

[0036] It should be noted that when the air duct 11 is directed to a certain device to blow air for heat dissipation, the wind will still carry the heat through the dustproof net 2 and be blown out to the outside of the high and low voltage switch cabinet;

[0037] At least one of the three blowing bins 1 must be kept not threadedly connected to the connecting seat 10 .

[0038] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
