Description

Technical Field

[0001] The utility model relates to a heat dissipation mechanism, in particular to a roof-lifting structure for a frequency conversion cabinet. Background Art

[0002] Frequency converter cabinets are a type of low-voltage complete equipment. Their primary component is a frequency converter, which controls the motor's speed and power. The cabinet's primary busbars are mounted on the top of the cabinet, generating significant heat during operation. Failure to dissipate this heat effectively compromises the busbar's current-carrying capacity and reduces the product's lifespan. Manufacturers typically add auxiliary devices to dissipate heat, such as exhaust fans or ventilation fans. This increases product cost. With this in mind, we designed an innovative, lifting-top structure for frequency converter cabinets. Utility Model Content

[0003] The utility model aims to solve the above-mentioned defects and provides a lifting roof structure for a frequency conversion cabinet.

[0004] In order to overcome the defects existing in the background technology, the technical solution adopted by the present invention to solve its technical problems is: this lifting roof structure for the frequency conversion cabinet includes a frequency conversion cabinet main body, and a main bus is provided on the side of the upper end surface of the frequency conversion cabinet main body. The upper end of the frequency conversion cabinet main body, located above the main bus, is provided with a lifting roof component for overall heat dissipation and safety protection.

[0005] According to another embodiment of the present invention, the lifting roof assembly further includes a top cover plate installed on the top of the cabinet body and a lifting roof protection plate located at the upper end of the top cover plate, two front support rods and two rear support rods are provided between the top cover plate and the lifting roof protection plate, the lifting roof protection plate is arranged at an angle, the left side, right side and rear of the lifting roof protection plate are provided with upward bending edges, the front side of the lifting roof protection plate is provided with an upper waterproof edge, the left side, right side and rear of the top cover plate are provided with upward bending edges, the surface of the top cover plate is evenly arranged with shutter flange holes, and the flanges are facing upward, and the front of the top cover plate is provided with a lower waterproof edge.

[0006] According to another embodiment of the present invention, the cross-sections of the upper waterproof edge and the lower waterproof edge are V-shaped.

[0007] According to another embodiment of the present invention, the height of the rear support rod is greater than that of the front support rod, so that the angle between the roof protection plate and the horizontal plane is 2°-5°.

[0008] According to another embodiment of the present invention, a convex hole is further provided on the top surface of the roof-lifting protective plate at the mounting holes of the front support rod and the rear support rod, and the convex surface of the convex hole faces upward.

[0009] According to another embodiment of the present invention, a large number of long slots are further provided inside the top cover plate, serving as internal heat diffusion channels.

[0010] The beneficial effects of this utility model are as follows: This lifting roof structure for a frequency converter cabinet primarily divides the top into two layers: the lower layer for ventilation and heat dissipation, and the upper layer for rain protection. This layered design enables natural ventilation and heat dissipation in the frequency converter cabinet, eliminating the need for air conditioning fans, saving costs and improving reliability. This design is not only applicable to frequency converter cabinets, but can also be used in incoming line and filter cabinets. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, but not all of them. The embodiments of the basic utility model and all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present utility model.

[0018] A lifting structure for a frequency conversion cabinet, such as Figure 1 As shown, a non-fan cooling ventilation mode is used. The main components include the main busbar 2 and the lifting assembly 3. The inverter cabinet body 1 is the main body of the switchgear assembly and consists of primary and secondary components, copper busbars, and accessories. The main busbar 2, also known as the horizontal busbar, is located at the top of the equipment. It transmits power to the switches and the next-level load via vertical copper busbars within the cabinet, carrying the power load of the entire equipment section. Both sides of the main busbar extend out of the cabinet body for connection to the main circuits of other cabinets.

[0019] like Figure 1-4 As shown, the roof lifting assembly 3 includes a top cover plate 8 installed on the top of the cabinet body and a roof lifting protection plate 5 located at the upper end of the top cover plate 8. Two front support rods 6 and two rear support rods 9 are provided between the top cover plate 8 and the roof lifting protection plate 5. The roof lifting protection plate 5 is inclined. The left side, right side and rear part of the roof lifting protection plate 5 are provided with upward bending edges. The front side of the roof lifting protection plate 5 is provided with an upper waterproof edge 11. The left side, right side and rear part of the top cover plate 8 are provided with upward bending edges. The shutter flange holes 4 are evenly arranged on the plate surface of the top cover plate 8, and the flanges thereof are facing upward. The front of the top cover plate 8 is provided with a lower waterproof edge 12.

[0020] The lifting assembly 3 is arranged at the top of the switchgear, and its main function is to provide effective ventilation, heat dissipation and safety protection for the equipment. The lifting protection plate 5 is placed at the top, and its left, right and rear sides are all bent upwards. The front side is provided with an upper waterproof edge 11, and the cross-section of the waterproof edge is V-shaped. The rod of the front support rod 6 is made of hexagonal steel and has threads at both ends. It is installed on the left and right sides of the front end of the lifting protection plate 5. The rear support rod 9 is also made of hexagonal steel and has threads at both ends. It is arranged on the left and right sides of the rear end. The height of the rear support rod 9 is greater than that of the front support rod 6. After installation, the lifting protection plate will tilt forward. When rain falls, it will flow along the slope to the waterproof edge, and then flow to the outside from both sides. The gasket 7 is used to fix the front support rod and is installed on both sides of the front and rear support rods. The top cover plate 8 is mounted on top of the inverter cabinet body 1. Louvered flange holes 4 are evenly distributed on the plate surface, with the flanges facing upward for ventilation and heat dissipation. A lower waterproof edge 12 is provided in front of the top cover plate to divert rainwater from falling onto it, preventing it from damaging the equipment. The lower ends of the front and rear support rods 6 and 9 are fixed to the top cover plate. The four mounting holes of the roof protection plate 5 are provided with raised holes 10, with the raised surface of the raised holes 10 facing upward to prevent rainwater from flowing in along the screws.

[0021] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
