Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a self-adjusting power distribution cabinet. Background Technology

[0002] In power distribution systems, the distribution cabinet is a core piece of equipment, and its internal electrical components generate a significant amount of heat during operation. Existing distribution cabinets primarily rely on heat sinks on the sides of the cabinet for natural convection cooling, but this passive cooling method has significant drawbacks:

[0003] Poor heat dissipation efficiency: Natural convection is greatly affected by ambient temperature and air flow, especially in high temperature or enclosed space, where heat is easily accumulated, causing the component temperature to rise excessively.

[0004] Dust blockage risk: In industrial environments, dust particles can easily adhere to the surface of the heat sink, forming a heat insulation layer. In severe cases, this can completely block the heat dissipation holes, causing the heat dissipation system to fail.

[0005] Therefore, there is an urgent need for a power distribution cabinet temperature control solution that requires no external energy and has both heat dissipation and self-cleaning functions, in order to solve the technical problems of low heat dissipation efficiency, easy blockage, and high maintenance costs in the existing technology. Utility Model Content

[0006] The purpose of this utility model is to provide a self-adjusting power distribution cabinet, which realizes the circulation and discharge of hot air inside the cabinet and the self-cleaning of the heat dissipation plate through the linkage mechanism of electric cylinder driving air tank-rotating tube, effectively improving the heat dissipation reliability and environmental adaptability of the power distribution cabinet.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model discloses a self-adjusting power distribution cabinet, including a cabinet body, a heat dissipation plate on the side of the cabinet body, an air tank inside the cabinet body, a rotating tube that can rotate in a specific direction being coaxially sleeved inside the air tank, and a piston plate inside the rotating tube; a dual-circuit reversing pipeline is connected to the outside of the air tank; and a first power mechanism is connected to the piston plate to drive it to reciprocate.

[0009] A further embodiment: The dual-circuit reversing pipeline includes a first intake pipe and a first exhaust pipe located on the first side of the piston plate, and a second intake pipe and a second exhaust pipe located on the second side of the piston plate.

[0010] A further embodiment: the air intake end of the second air intake pipe is connected to the edge of the electrical components inside the cabinet; the air intake end of the first air intake pipe is located in the cabinet space above the electrical components; both the first exhaust pipe and the second exhaust pipe are connected to the heat sink.

[0011] A further embodiment: the dual-circuit reversing pipeline also includes an upper air hole and a lower air hole opened on the side wall of the rotating pipe; the upper air hole can be selectively connected to the first exhaust pipe or the first intake pipe, and the lower air hole can be selectively connected to the second exhaust pipe or the second intake pipe.

[0012] A further solution: The first power mechanism is an electric cylinder, which is located on the top of the cabinet.

[0013] A further solution: the opening of the gas cylinder is sealed against the inner wall of the top side of the cabinet, and the telescopic end of the electric cylinder passes through the top wall of the cabinet and is connected to the piston plate.

[0014] A further solution: The heat sink is provided with a connecting plate on the inner side for fixing the two ends of the electrical components.

[0015] A further solution includes a second power mechanism for driving the rotating tube to rotate in an directional manner. The second power mechanism includes an upper guide groove on the upper edge of the rotating tube, a lower guide groove on the lower edge of the rotating tube, and an elastic telescopic member on the outer edge of the piston plate.

[0016] A further embodiment: the elastic telescopic component includes a spring built into the piston plate, and a slider connected to the telescopic end of the spring.

[0017] A further embodiment: the upper guide groove and the lower guide groove have single arc surfaces with opposite inclination directions.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention utilizes a first power mechanism to drive a piston plate to reciprocate within a rotating tube. Combined with the 180° rotation of the rotating tube and a dual-circuit reversing pipeline, directional switching of the airflow is achieved. The upper and lower chambers formed by the piston plate in the rotating tube alternately discharge hot air, achieving continuous cooling. The discharged hot air impacts the heat sink plate at high speed, achieving self-cleaning and preventing dust from clogging the heat dissipation holes. The rotating tube automatically reverses direction through the mechanical linkage of upper and lower guide grooves and a slider, requiring no additional power source. This invention features a compact and maintenance-free overall structure, suitable for high-temperature and dusty environments, and significantly improves temperature control reliability and environmental adaptability compared to traditional natural heat dissipation solutions.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Please see Figure 1-4 In this embodiment, a self-regulating power distribution cabinet includes a cabinet body 1. The cabinet body 1 has a perforated heat dissipation plate 2 on its side. An air tank 3 is housed inside the cabinet body 1. A rotating tube 4, which can rotate relative to the air tank 3, is coaxially fitted inside the air tank 3. A piston plate 5 is installed in the rotating tube 4. The piston plate 5 is connected to a first power mechanism 6 for driving its reciprocating motion along the axial direction of the rotating tube 4. A second power mechanism 15 is also included for driving the rotating tube 4 to rotate in a specific direction. A dual-circuit reversing pipeline is connected to the outside of the air tank 3. Through the reciprocating motion of the piston plate 5 driven by the first power mechanism 6 and the directional rotation of the rotating tube 4, a forced circulation path is formed: hot air inside the cabinet → stored in the air tank → discharged through the heat dissipation plate. This significantly improves the efficiency compared to traditional natural heat dissipation.

[0030] Furthermore, the dual-circuit reversing pipeline includes a first intake pipe 7 and a first exhaust pipe 9 located on the first side of the piston plate 5, and a second intake pipe 8 and a second exhaust pipe 10 located on the second side of the piston plate 5. The intake end of the second intake pipe 8 is connected to the edge of the electrical component 11 inside the cabinet 1; the intake end of the first intake pipe 7 is located within the space of the cabinet 1 above the electrical component 11; and both the first exhaust pipe 9 and the second exhaust pipe 10 are connected to the heat sink 2.

[0031] Furthermore, the dual-circuit reversing pipeline also includes an upper air hole 41 and a lower air hole 42 opened on the side wall of the rotating pipe. The upper air hole 41 can be selectively connected to the first exhaust pipe 9 or the first intake pipe 7, and the lower air hole 42 can be selectively connected to the second exhaust pipe 10 or the second intake pipe 8, thereby realizing air path switching.

[0032] Furthermore, the first power mechanism 6 is an electric cylinder, which is located at the top of the cabinet 1.

[0033] Furthermore, the opening of the gas cylinder 3 is sealed against the inner wall of the top side of the cabinet 1, and the telescopic end of the electric cylinder passes through the top wall of the cabinet 1 and is connected to the piston plate 5. The electric cylinder drives the piston plate 5 to move up and down reciprocally.

[0034] Furthermore, the inner side of the heat sink 2 is provided with connecting plates 12 for fixing the two ends of the electrical component 11. The electrical component 11 is the main heat source of the distribution cabinet. Its two ends are connected to the heat sink 2 through the connecting plates 12, as close as possible to the heat dissipation vents to increase the efficiency of natural heat dissipation.

[0035] Furthermore, heat dissipation plates 2 are symmetrically arranged on both sides of the cabinet 1. The first exhaust pipe 9 and the second exhaust pipe 10 are respectively connected to the two heat dissipation plates 2 to achieve balanced heat dissipation.

[0036] Furthermore, the second power mechanism 15 includes an upper guide groove 43 formed on the upper edge of the rotating tube 4, a lower guide groove 44 formed on the lower edge of the rotating tube 4, and an elastic telescopic member provided on the outer edge of the piston plate 5 that can selectively engage with either the upper guide groove 43 or the lower guide groove 44. This second power mechanism 15 enables the rotating tube 4 to rotate 180° in both directions, thereby changing the airflow path.

[0037] Furthermore, the elastic telescopic component includes a spring 13 built into the piston plate 5, and a slider 14 connected to the telescopic end of the spring 13. As the spring 13 extends and retracts, the slider 14 slides freely in and out of the upper guide groove 43 and the lower guide groove 44, realizing the directional rotation of the rotating tube 4. It should be particularly noted that the connection between the piston plate 5 and the rotating tube 4 should be sealed as much as possible. If a complete seal is not possible, slight leakage will have little impact on the overall heat exchange circulation and can be ignored.

[0038] Furthermore, the upper guide groove 43 and the lower guide groove 44 have single arc surfaces with opposite inclination directions. When the piston plate 5 moves upward to its limit position, the slider 14 slides along the inclined arc surface of the upper guide groove 43, thereby pushing the rotating tube 4 to rotate. Similarly, when the piston plate 5 moves downward to its limit position, the slider 14 slides along the inclined arc surface of the lower guide groove 44, thereby pushing the rotating tube 4 to rotate in the opposite direction, thus accurately switching the air path direction and ensuring the continuity of the cyclic switching. To ensure the stability of the rotation, there are two upper guide grooves 43 and two lower guide grooves 44.

[0039] Please continue reading. Figure 5-6 The operating mechanism of this utility model for switching the gas path is as follows:

[0040] Piston plate 5 divides rotating tube 4 into upper and lower chambers. When piston plate 5 moves upward, upper air hole 41 connects with first exhaust pipe 9, and lower air hole 42 connects with second suction pipe 8. First suction pipe 7 and second exhaust pipe 10 are both blocked, preventing airflow. Piston plate 5 pushes the gas in the upper chamber of rotating tube 4 upward, which is then blown at high speed onto heat dissipation plate 2 through first exhaust pipe 9, achieving heat dissipation and self-cleaning of heat dissipation plate 2. Due to the upward movement of piston plate 5, negative pressure is formed in the lower chamber of rotating tube 4, and hot air in cabinet 1 is drawn into the lower chamber through second suction pipe 8 for storage.

[0041] The electric cylinder drives the piston plate 5 downward to its limit position (bottoming out), and the slider 14 engages with the lower guide groove 44, driving the rotating tube 4 to rotate 180°. This switches the air path; the upper air port 41 connects with the first intake pipe, and the lower air port 42 connects with the second exhaust pipe 10. Both the first exhaust pipe 9 and the second intake pipe 8 are blocked, preventing airflow. The piston plate 5 presses the gas into the lower cavity of the rotating tube 4, causing the stored hot gas to be discharged from the second exhaust pipe 10. Simultaneously, a negative pressure is generated in the upper cavity, drawing in and storing the hot gas from the cabinet 1 through the first intake pipe 7. The piston plate 5 moves upward again, and the slider 14 slides out of the lower guide groove 44. When the piston plate 5 reaches its limit position, it slides into the upper guide groove 43 and engages, switching the air path again. The lower cavity draws in hot gas, and the hot gas in the upper cavity is forced out of the cabinet 1. This cycle repeats, achieving continuous cooling.
