Description

Technical Field

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

[0002] Distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final-level equipment in a power distribution system. A cabinet is a general term for a motor control center. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, while motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit from the previous-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Chinese patent CN114825123A discloses a power distribution cabinet with self-regulating temperature. When the temperature inside the cabinet is too high, the motor is triggered by a triggering mechanism. The fan blades drive the magnet to rotate, realizing the reciprocating flow of water and the reciprocating expansion and contraction of the air bag. This continuously adsorbs and cools the equipment box and cleans the air intake filter, ensuring that the airflow can smoothly pass through the air intake filter into the cabinet and carry away the heat.

[0004] Although the above solutions utilize fan blades, water, and other structures to dissipate heat from the cabinet, when the cabinet is at a low temperature and is in a blowing state, the airflow will exacerbate the continuous drop in temperature inside the cabinet. There is a risk that the normal operation of the equipment inside the cabinet may be affected due to excessively low temperature. This makes it difficult for the power distribution cabinet to quickly and effectively adjust its heat dissipation or heat preservation strategies when the ambient temperature fluctuates significantly, and it is difficult to meet the self-regulation requirements of the power distribution cabinet under different operating conditions. Summary of the Invention

[0005] To address the aforementioned issues, this utility model proposes a temperature-self-regulating power distribution cabinet. This effectively solves the problem that when the cabinet is in a low-temperature, drafty state, airflow will exacerbate the continuous drop in temperature inside the cabinet, posing a risk that the normal operation of the equipment inside the cabinet may be affected by excessively low temperatures. This makes it difficult for the power distribution cabinet to quickly and effectively adjust its heat dissipation or insulation strategies when the ambient temperature fluctuates significantly, and it is difficult to meet the temperature self-regulation requirements of the power distribution cabinet under different operating conditions.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A temperature-self-regulating power distribution cabinet, comprising: The cabinet has a first mounting groove on both sides, and a square frame is installed in each of the two first mounting grooves. Rotating rods arranged at equal intervals are rotatably connected in the square frame. A wind baffle is fixedly connected to each of the rotating rods. The square frame is divided into a blocking cavity and an air flow cavity by the wind baffle. An exhaust net is embedded in the bottom surface of the cabinet.

[0007] The second mounting slot is located on the inner top wall of the cabinet, and an axial flow fan is installed in the second mounting slot.

[0008] A cover plate, which covers the upper surface of the cabinet.

[0009] The adjustment component, located inside the cabinet, synchronously rotates the rotating rod and raises and lowers the cover plate, and the rotating rod drives the baffle plate to rotate within the frame to adjust the size of the airflow cavity.

[0010] Furthermore, a base is provided at the bottom of the cabinet, and two sets of uprights are fixedly connected to the base, with the top ends of the uprights fixedly connected to the cabinet.

[0011] Furthermore, a filter cylinder is fixedly connected to the cover plate, and the filter cylinder is fitted onto the top of the cabinet.

[0012] Furthermore, the adjustment assembly includes an electric push rod installed on the bottom surface of the cabinet. The telescopic end of the electric push rod is fixedly connected to a linkage rod, and both ends of the linkage rod are fixedly connected to lifting rods. The top end of the lifting rod passes through the cabinet and is fixedly connected to the cover plate.

[0013] Furthermore, a gear is fixedly connected to the rotating rod, and a rack is fixedly connected to the lifting rod, with the gear and rack meshing together.

[0014] Furthermore, a temperature detector and a controller are installed inside the cabinet, and the controller is electrically connected to the electric push rod through the temperature detector.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention uses an electric push rod to lower the cover plate, ensuring it tightly covers the top of the cabinet to prevent large amounts of cold air from entering. Simultaneously, a rack and pinion mechanism drives a rotating rod to rotate a baffle plate, reducing the side airflow cavity and minimizing air circulation within the cabinet. This achieves active insulation, preventing low temperatures from affecting the normal operation of electrical components. The electric push rod also raises the cover plate to create an air intake cavity, where an axial fan draws in outside air from the top. The rotating baffle plate expands the airflow cavity, and together with the bottom exhaust screen, forms a highly efficient top-to-bottom airflow channel that quickly removes heat. This meets the temperature regulation needs of the distribution cabinet under different operating conditions, significantly improving the stability of equipment operation.

Detailed Implementation

[0018] 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.

[0019] like Figures 1 to 4 As shown, a temperature-regulating power distribution cabinet includes a cabinet body 1, a second mounting slot 13, a cover plate 11, and an adjustment component.

[0020] In this embodiment, two cabinet doors 2 are hinged to the cabinet body 1. The cabinet doors 2 are designed with handles. Electrical components 15 are installed inside the cabinet body 1. When it is necessary to inspect or adjust the electrical components 15, the cabinet doors 2 can be opened and closed to facilitate the workers to inspect the electrical components 15. The cabinet body 1 is designed with through holes, through which the lines connected to the electrical components 15 can extend from inside the cabinet body 1 to the outside.

[0021] In this embodiment, in order to raise the bottom of the cabinet 1 to a certain height, a base 4 is provided at the bottom of the cabinet 1. Two sets of uprights 3 are fixedly connected to the base 4, and the top of the uprights 3 is fixedly connected to the cabinet 1.

[0022] The cabinet 1 is supported by the uprights 3 and the base 4, so that there is enough space between the bottom of the cabinet 1 and the ground.

[0023] The cabinet 1 has a first mounting groove 7 on both sides, and a square frame 8 is installed in each of the two first mounting grooves 7. Rotating rods 9 are rotatably connected in the square frame 8 and are arranged at equal intervals. A wind baffle 10 is fixedly connected to each rotating rod 9. The square frame 8 is divided into a blocking cavity and an air flow cavity through the wind baffle 10. An exhaust net 5 is embedded on the bottom surface of the cabinet 1.

[0024] The size of the blocking cavity and the airflow cavity can be adjusted by changing the rotation angle of the wind deflector 10 within the frame 8; that is, when the blocking cavity becomes larger, the airflow cavity will become smaller.

[0025] In this embodiment, the second mounting groove 13 is opened on the inner top wall of the cabinet 1. An axial flow fan 14 is installed in the second mounting groove 13. After the axial flow fan 14 is started, it will blow the outside air from the top of the cabinet 1 to the inside of the cabinet 1, and after absorbing heat in the cabinet 1, it will be discharged from the cabinet 1 through the exhaust net 5.

[0026] The cover plate 11 covers the upper surface of the cabinet 1, and a filter cylinder 12 is fixedly connected to the cover plate 11, and the filter cylinder 12 is sleeved on the top of the cabinet 1.

[0027] The filter cylinder 12 is a mesh cylinder structure with a filter screen. After the cover plate 11 moves upward, an air inlet cavity is formed between the cover plate 11 and the cabinet 1. The filter cylinder 12 can filter the air entering the air inlet cavity.

[0028] In this embodiment, the adjustment component is set inside the cabinet 1. It synchronously completes the rotation of the rotating rod 9 and the lifting and lowering of the cover plate 11. The rotating rod 9 drives the baffle plate 10 to rotate within the frame 8 to adjust the size of the airflow cavity.

[0029] The adjustment component includes an electric push rod 6 installed on the bottom surface of the cabinet 1. The telescopic end of the electric push rod 6 is fixedly connected to a linkage rod 16. Both ends of the linkage rod 16 are fixedly connected to lifting rods 17. The top end of the lifting rod 17 passes through the cabinet 1 and is fixedly connected to the cover plate 11.

[0030] The extension end of the electric push rod 6 drives the linkage rod 16 to move upward inside the cabinet 1. Under the action of the lifting rod 17, the cover plate 11 can be moved upward. After the axial flow fan 14 is started, it is convenient for the external air to be transported to the inside of the cabinet 1 by the axial flow fan 14.

[0031] Furthermore, a gear 18 is fixedly connected to the rotating rod 9, and a rack 19 is fixedly connected to the lifting rod 17, with the gear 18 meshing with the rack 19.

[0032] As the cover plate 11 moves upward, the rack 19 on the lifting rod 17 meshes with the gear 18, causing the rotating rod 9 to drive the baffle plate 10 to rotate, increasing the airflow cavity and accelerating the flow of gas in the cabinet 1, thereby improving the heat dissipation effect of the cabinet 1.

[0033] In this embodiment, a temperature detector and a controller are installed inside the cabinet 1, and the controller is electrically connected to the electric push rod 6 through the temperature detector.

[0034] The temperature inside the cabinet 1 is monitored in real time by a temperature detector. The installation position of the temperature detector can be adjusted as needed. When the temperature inside the cabinet 1 is detected to be too low, the cover plate 11 is moved down by the electric push rod 6 and covered on the cabinet 1. After the cover plate 11 is moved down, the rotating rod 9 drives the baffle plate 10 to rotate, reducing the air flow cavity and reducing the air circulation between the inside of the cabinet 1 and the outside.

[0035] When the temperature inside the cabinet 1 is too high, the electric push rod 6 drives the cover plate 11 to move upward, so that there is a wall between the cover plate 11 and the cabinet 1. At the same time, the axial flow fan 14 starts to draw outside air into the interior of the cabinet 1. At this time, the rotating rod 9 drives the baffle plate 10 to rotate, which increases the air flow cavity and speeds up the flow efficiency of the gas inside the cabinet 1, thereby achieving the effect of reducing the temperature inside the cabinet 1.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
