Description

Technical Field

[0001] The utility model relates to the technical field of distribution cabinets, and specifically, to a distribution cabinet with adjustable function partition sizes. Background Technique

[0002] The distribution cabinet is the end equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. Generally, a pallet is installed inside the distribution cabinet. The equipment installed inside the distribution cabinet will be placed on the pallet. Since the sizes of the equipment installed inside the distribution cabinet are different, the required installation space positions of the equipment are also different. Therefore, the height of the pallet needs to be adjusted.

[0003] Most of the pallets installed inside the existing distribution cabinets are fixed inside the distribution cabinets. The height of the pallet is not easy to adjust, so that when the equipment inside the distribution cabinet is installed, the space inside the distribution cabinet cannot be utilized well, resulting in a large waste of the space inside the distribution cabinet. At the same time, when a larger electrical equipment is installed inside a smaller installation area, since the gap between the equipment and the inner wall of the cabinet is small, the air in the gap is difficult to flow, and the heat generated when the electrical equipment operates is easy to accumulate in the narrow gap, increasing the possibility of the electrical equipment malfunctioning due to high temperature. In view of this, we propose a distribution cabinet with adjustable function partition sizes. Summary of the Invention

[0004] The purpose of the utility model is to provide a distribution cabinet with adjustable function partition sizes to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, one of the purposes of the utility model is to provide a distribution cabinet with adjustable function partition sizes, including a cabinet body. Guide tubes are arranged at the four corners inside the cabinet body. The two ends of each guide tube are respectively fixedly connected to the top and bottom of the cabinet body. A plurality of vertically arranged carrier plates are arranged between the plurality of guide tubes. The four corners of the carrier plate are slidably connected to the guide tubes. A height adjustment mechanism is arranged on the lower side of the carrier plate. The height adjustment mechanism is arranged at a position close to one of the guide tubes. The height adjustment mechanism is used to adjust the vertical height of the carrier plate and limit the position of the carrier plate after stopping adjusting the height of the carrier plate. An air cooling mechanism is arranged on the plurality of guide tubes. The air cooling mechanism is used to blow air into the space inside the cabinet body.

[0006] As a further improvement of the technical solution, the height adjustment mechanism includes a rack fixedly connected to the side wall of one of the guide tubes. The carrier plate is slidably sleeved outside the rack. A transmission rod is rotatably connected to the lower surface of the carrier plate. A gear and a worm gear are fixedly connected to the outer wall of the transmission rod. The gear meshes with the rack. A worm is rotatably connected to the lower surface of the carrier plate. The worm meshes with the worm gear.

[0007] As a further improvement of the technical solution, the air-cooling mechanism includes blowing holes formed in the side wall of the guiding pipe. A plurality of the blowing holes are linearly arranged in an array. The top of the cabinet body is fixedly connected with a hollow frame. The upper end of the guiding pipe penetrates through the top of the cabinet body and extends into the interior of the hollow frame. An axial-flow fan is fixedly installed on the side wall of the hollow frame.

[0008] As a further improvement of the technical solution, a plurality of ventilation grooves are formed in the side wall of the carrier plate. The upper surface of the carrier plate at a position directly above the ventilation grooves is set as an electrical installation area. A plurality of groups of the blowing holes are distributed around the electrical installation area.

[0009] As a further improvement of the technical solution, a skylight is formed in the top of the cabinet body. The skylight is located inside the hollow frame.

[0013] 2. For the power distribution cabinet with adjustable function partition size, when the electrical equipment in the cabinet body is operating, by starting the axial-flow fan, air flow is made to blow through a plurality of blowing holes towards the electrical equipment installed on each carrier plate, so as to perform comprehensive air-cooling heat dissipation on multiple electrical equipment in the cabinet body and ensure the normal operation of the electrical equipment.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0023] Please refer to Figure 1 As shown in the figure, this embodiment provides a power distribution cabinet with adjustable function partition size, including a cabinet body 1. Guide tubes 2 are arranged at the four corners inside the cabinet body 1. Both ends of the guide tubes 2 are fixedly connected to the top and bottom of the cabinet body 1 respectively. A number of carrier plates 3 are arranged up and down between several guide tubes 2. The four corners of the carrier plate 3 are slidably connected to the guide tubes 2. A number of ventilation slots are opened on the side wall of the carrier plate 3, and a number of ventilation slots are distributed in a linear array. The position directly above the ventilation slots on the upper surface of the carrier plate 3 is set as the electrical installation area. The electrical equipment inside the power distribution cabinet is installed in the electrical installation area on the carrier plate 3. A height adjustment mechanism 4 is arranged below the carrier plate 3. The height adjustment mechanism 4 is arranged at a position close to one of the guide tubes 2. The height adjustment mechanism 4 is used to adjust the vertical height of the carrier plate 3 and limit the position of the carrier plate 3 after stopping adjusting the height of the carrier plate 3. By adjusting the positions of the respective carrier plates 3 inside the cabinet body 1, the occupied space of each electrical installation area inside the cabinet body 1 is allocated, so that electrical equipment of different sizes can be installed in the electrical installation areas of appropriate sizes, improving the space utilization rate inside the cabinet body 1. An air cooling mechanism 5 is arranged on several guide tubes 2. The air cooling mechanism 5 is used to blow air into the internal space of the cabinet body 1 to perform air cooling on the electrical equipment installed in the cabinet body 1 and enhance the heat dissipation performance of the electrical equipment.

[0024] A number of electrical devices within the cabinet body 1 are respectively installed in the electrical installation areas on a number of carrier plates 3. However, due to the different sizes of the electrical devices, there are situations where smaller electrical devices are installed in larger electrical installation areas, resulting in wasted space, and larger electrical devices cannot be installed in smaller electrical device areas. Therefore, it is necessary to allocate the sizes of the electrical installation areas to install electrical devices of different sizes in the appropriately sized electrical installation areas, making efficient use of the space within the cabinet body 1. The spatial size of the electrical installation area is determined by the distance between two adjacent carrier plates 3 and the distance between the uppermost carrier plate 3 and the inner top surface of the cabinet body 1. Therefore, by adjusting the distance between two adjacent carrier plates 3 and the distance between the uppermost carrier plate 3 and the inner top surface of the cabinet body 1, the sizes of the electrical installation areas within the cabinet body 1 can be allocated. To meet this requirement, the structure of the height adjustment mechanism 4 is refined as follows. Refer to Figure 2 The height adjustment mechanism 4 includes a rack 41 fixedly connected to the side wall of one of the guide tubes 2. The carrier plate 3 is slidably sleeved outside the rack 41. A transmission rod 42 is rotatably connected to the lower surface of the carrier plate 3. A gear 43 and a worm gear 44 are fixedly connected to the outer wall of the transmission rod 42. The gear 43 meshes with the rack 41. A worm 45 is rotatably connected to the lower surface of the carrier plate 3. The worm 45 meshes with the worm gear 44. One side of the cabinet body 1 is hinged with a cabinet door. A rotating plate is fixedly connected to one end of the worm 45 close to the cabinet door. The rotating plate is located between one of the guide tubes 2 and the cabinet door. When an operator opens the cabinet door and twists the worm 45 through the rotating plate, through the meshing transmission between the worm 45 and the worm gear 44, the worm gear 44 drives the transmission rod 42 and the gear 43 to rotate. Through the meshing transmission between the gear 43 and the rack 41, the carrier plate 3 moves vertically along the outer walls of a number of guide tubes 2. After adjusting the carrier plate 3 to a predetermined height, stop rotating the worm 45. Due to the self-locking property of the transmission between the worm 45 and the worm gear 44, the worm gear 44 will not rotate without rotating the worm 45. The worm gear 44 restricts the rotation of the transmission rod 42 and the gear 43, enabling the gear 43 and the rack 41 to cooperate to limit the vertical movement of the carrier plate 3, so that the height of the carrier plate 3 will not change. By adjusting the heights of a number of carrier plates 3 successively, the distance between two adjacent carrier plates 3 and the distance between the uppermost carrier plate 3 and the inner top surface of the cabinet body 1 can be adjusted, achieving the purpose of allocating the electrical installation areas within the cabinet body 1.

[0025] When the electrical devices in the cabinet cooperate, they will generate heat. If the heat generated by the electrical devices cannot be promptly dissipated to the outside of the cabinet body 1, resulting in the accumulation of heat within the cabinet body 1, the electrical devices may malfunction due to high temperature, and even catch fire, posing a safety hazard. In order to efficiently dissipate the heat of the electrical devices installed in each electrical installation area and prevent the accumulation of heat within the cabinet body 1, the structure of the air cooling mechanism 5 is refined as follows. Refer to Figure 3 and Figure 4, the air-cooling mechanism 5 includes air-blowing holes 51 formed in the side wall of the guiding pipe 2. A number of air-blowing holes 51 are linearly arrayed, and several groups of air-blowing holes 51 are distributed around the electrical installation area. The top of the cabinet body 1 is fixedly connected with a hollow frame 52. The upper end of the guiding pipe 2 penetrates through the top of the cabinet body 1 and extends into the interior of the hollow frame 52. An axial-flow fan 53 is fixedly installed on the side wall of the hollow frame 52. After the axial-flow fan 53 is started, the air outside the cabinet body 1 is sucked into the interior of the hollow frame 52. The air in the hollow frame 52 then enters the interior of several guiding pipes 2 and is blown through several air-blowing holes 51 towards the electrical equipment installed on each carrier plate 3. After the air flow passes through the surface of the electrical equipment, it absorbs heat and warms up through heat exchange. The electrical equipment cools down due to the loss of part of the heat. A skylight is formed in the top of the cabinet body 1, and the skylight is located inside the hollow frame 52. The heated air flow is discharged from the cabinet body 1 through the skylight, realizing the air-cooling heat dissipation of the electrical equipment and avoiding the accumulation of heat in the cabinet body 1. A rain shield is fixedly connected to the top of the cabinet body 1, and the rain shield shields the directly upper parts of the hollow frame 52, the axial-flow fan 53 and the skylight. When the cabinet body 1 installed outdoors encounters rainy weather, the rain shield blocks the rain from entering the interior of the cabinet body 1 through the skylight, preventing the rain from wetting the axial-flow fan 53 and causing its short-circuit failure.

[0026] In summary, the working principle of this solution is as follows: The space of each electrical installation area in the cabinet body 1 is allocated according to the sizes of each electrical equipment. The allocation steps are as follows: Rotate the worm 45. Through the meshing transmission between the worm 45 and the worm gear 44, the worm gear 44 drives the transmission rod 42 and the gear 43 to rotate. Through the meshing transmission between the gear 43 and the rack 41, the carrier plate 3 moves vertically along the outer walls of several guiding pipes 2. After adjusting the carrier plate 3 to the predetermined height, stop rotating the worm 45. The heights of several carrier plates 3 are adjusted successively in the above manner to adjust the distance between two adjacent carrier plates 3 and the distance between the uppermost carrier plate 3 and the inner top surface of the cabinet body 1, achieving the purpose of allocating each electrical installation area in the cabinet body 1. Electrical equipment of different sizes are respectively installed on different carrier plates 3, so that electrical equipment of different sizes are placed in the electrical installation areas of suitable sizes, completing the installation of the electrical equipment. When using this power distribution cabinet, start the axial-flow fan 53 to conduct comprehensive air-cooling heat dissipation on each electrical equipment in the cabinet body 1 to ensure the normal operation of the electrical equipment.
