Description

Technical Field

[0001] The present invention relates to the technical field of power distribution cabinets, and in particular to a power distribution cabinet with a temperature regulating function. Background Art

[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits.

[0003] When the electrical components in the distribution cabinet are running, the temperature inside the cabinet increases accordingly. In order to ensure the temperature inside the cabinet, an inlet fan is set. When the inlet fan is turned on, the external airflow is drawn into the cabinet for heat dissipation. A filter is installed in the cabinet to filter the external airflow. However, the filter in the cabinet is not cleaned in time at present, so that foreign impurities will accumulate on the filter, causing the airflow to flow slowly, and the heat dissipation area of ​​the heat dissipation port on the cabinet is small, which makes it difficult to quickly discharge the heat energy in the cabinet; when the distribution cabinet encounters rainy and snowy weather, rainwater will penetrate into the cabinet through the top of the distribution cabinet, and the snow will accumulate on the top of the distribution cabinet. The heat energy in the cabinet will melt the snow accumulated on the top, which will cause rainwater to still enter the distribution cabinet, making it difficult to protect the electrical components in the distribution cabinet. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that heat energy of a power distribution cabinet is difficult to be quickly discharged, and to propose a power distribution cabinet with a temperature regulation function.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 1-Figure 6 A power distribution cabinet with temperature regulation function, comprising a cabinet 1 with electrical components, a temperature monitor 6, a controller 1, and an inlet fan 7 are electrically connected and installed in the cabinet 1, the temperature monitor 6 automatically samples and monitors the ambient temperature in real time through a temperature sensor, and the inlet fan 7 can absorb the external airflow into the cabinet 1 when rotating, thereby dissipating the heat of the electrical components in the cabinet 1, and a filter 8 and a heat sink 13 matched with the air outlet are installed in the cabinet 1;

[0028] The filter 8 is horizontally arranged at the bottom of the cabinet 1, and a connecting ear extending to the cabinet 1 is integrally connected to the filter 8, and a locking bolt connected to the cabinet 1 is threadedly connected to the connecting ear, and the connecting ear and the cabinet 1 are connected by the locking bolt. When the filter 8 needs to be disassembled, it is only necessary to remove the locking bolt, and by arranging the filter 8 in the cabinet 1, the filter 8 can filter the external airflow, thereby preventing dust from accumulating in the cabinet 1;

[0029] The heat sink 13 is pin-mounted on both sides of the cabinet 1. Ventilation holes corresponding to the heat sink 13 are provided on the cabinet 1. By providing two ventilation holes on the cabinet 1, when the through holes are opened, the contact area between the cabinet 1 and the outside world can be increased, so that the heat energy accumulated in the cabinet 1 can be quickly discharged from the ventilation holes on both sides.

[0030] A frame 14 for accommodating the heat sink 13 is fixedly installed on the cabinet 1, and the frame 14 is a concave structure. A sealing gasket 15 is installed in the heat sink 13 and the frame 14. By arranging the frame 14 on the cabinet 1 and arranging the sealing gasket 15 in contact with the heat sink 13 and the frame 14, when the heat sink 13 extends into the frame 14, the heat energy in the cabinet 1 can be sealed to prevent the loss of heat energy.

[0031] An unfolding assembly for unfolding the heat sink 13 is installed in the cabinet 1;

[0032] The unfolding assembly includes two rotating shafts 16 rotatably mounted in the cabinet 1, and a resisting rod 17 that resists the heat dissipation plate 13 is fixedly mounted on the rotating shaft 16;

[0033] A rotating assembly for driving two rotating shafts 16 to rotate is installed in the cabinet 1;

[0034] The rotating assembly includes a driven gear 18 fixedly sleeved on the rotating shaft 16, a telescopic rod 19 electrically connected to the controller 1 is fixedly installed in the cabinet 1, and a connecting rod 20 is fixedly connected to the output end of the telescopic rod 19, the temperature monitor 6 is arranged on the connecting rod 20, and an active rack 21 meshingly connected to the driven gear 18 is fixedly installed on the connecting rod 20;

[0035] When the temperature in the cabinet 1 is high, the temperature monitor 6 senses through the temperature sensor that the temperature in the cabinet 1 exceeds the specified threshold, and the telescopic rod 19 receives an opening signal, and the active rack 21 moves upward by driving the two rotating shafts 16 to drive in the opposite direction, and the rotating shaft 16 drives the resistance rod 17 to resist the heat sink 13 when it rotates in the opposite direction. After the heat sink 13 is subjected to force, it deflects with the pin point as the fulcrum to open the vent, so that the heat energy accumulated in the cabinet 1 can be quickly discharged outside the cabinet 1;

[0036] A cleaning brush 12 for cleaning the filter screen 8 is provided on the cabinet 1 through a movable member;

[0037] The moving part includes a motor 9 fixedly installed in the cabinet 1, and a screw rod 10 is fixedly connected to the output end of the motor 9. A matching nut 11 is provided on the sliding sleeve of the screw rod 10. A cleaning brush 12 is provided on the nut 11. The nut 11 is arranged horizontally. A long hole for guiding the cleaning brush 12 is provided on the cabinet 1. The long hole guides the cleaning brush 12, which not only ensures the moving direction of the cleaning brush 12, but also limits the moving direction of the nut 11. In order to maintain the flow speed of the air, the filter 8 needs to be cleaned regularly. Through the horizontal movement of the nut 11, the nut 11 drives the cleaning brush 12 to scrape the accumulated impurities on the filter 8, which can maintain the air flow speed in the cabinet 1;

[0038] The cabinet 1 is equipped with a controller 2, a camera, and a heater 5 which are electrically connected to a temperature monitor 6. The camera can monitor the inside of the cabinet 1 in real time. After the heater 5 is powered on, it transmits heat energy to the cabinet 1, which can prevent the temperature inside the cabinet 1 from being too low, thereby ensuring the normal operation of the electrical components. The cabinet 1 is equipped with a protective structure for waterproofing the electrical components.

[0039] The protective structure includes a support rod placed on the top of the cabinet 1, and an interception plate 2 for intercepting water and snow is fixedly installed on the support rod. It is additionally explained that the coverage area of ​​the interception plate 2 is larger than the area after the heat sink 13 is deflected, so that rainwater from above will not enter the cabinet 1 through the heat sink 13;

[0040] A heat dissipation pipe 3 for discharging heat energy is provided between the cabinet 1 and the interception plate 2. A heat dissipation hole 4 connected to the heat dissipation pipe 3 is provided on the interception plate 2. When encountering ice and snow weather, snow will accumulate on the interception plate 2 to form ice cubes. The heat dissipation pipe 3 transports the heat energy in the cabinet 1, so that the heat energy in the cabinet 1 enters the heat dissipation hole 4 through the heat dissipation pipe 3. When the heat energy flows in the heat dissipation hole 4, it can heat the interception plate 2. After the temperature of the interception plate 2 increases, it can melt the snow and ice cubes, effectively preventing snow water from seeping into the cabinet 1, and then protecting the electrical components in the cabinet 1. A fixing bolt connected to the cabinet 1 is threadedly connected on the support rod. The interception plate 2 is a V-shaped structure, and a one-way valve for controlling the flow direction is installed in the heat dissipation pipe 3. By arranging the one-way valve in the heat dissipation pipe 3, the flow velocity direction of the heat energy is limited.

[0041] By setting the interception plate 2 on the cabinet 1, the interception plate 2 can intercept rainwater. In addition, when encountering rainy and snowy weather, a water rope can be glued on the interception plate 2, and the water rope can smoothly transport the rainwater on the interception plate 2 to the ground, thereby avoiding splashing of rainwater;

[0042] It should be noted that the specific models and specifications of the temperature monitor 6, controller 1, fan 7, motor 9, controller 2, camera, heater 5, and telescopic rod 19 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0043] The present invention can be explained by the following operation mode:

[0044] When the electrical components are running, the temperature monitor 6 can monitor the temperature inside the cabinet 1;

[0045] The air inlet fan 7 is turned on, so that air enters the cabinet 1 from the bottom to dissipate heat for the electrical components;

[0046] The output end of the motor 9 drives the screw rod 10 to rotate, and the screw rod 10 drives the nut 11 to slide horizontally when rotating, and the nut 11 drives the cleaning brush 12 to slide in the long hole, so that the cleaning brush 12 can scrape the impurities on the filter screen 8;

[0047] When the temperature in the cabinet 1 exceeds a specified threshold, the temperature monitor 6 immediately sends a signal to the controller 1, and the controller 1 sends a signal to the telescopic rod 19;

[0048] The output end of the telescopic rod 19 contracts and drives the connecting rod 20 to move upward. When the connecting rod 20 moves upward, it drives the active rack 21 to pull the meshing driven gear 18. When the left active rack 21 moves upward, the left rotating shaft 16 rotates counterclockwise, and when the right active rack 21 moves upward, the right rotating shaft 16 rotates clockwise. When the rotating shaft 16 rotates, it drives the abutment rod 17 to move against the heat sink 13. The heat sink 13 deflects with the pin point as the fulcrum and disconnects from the frame 14, thereby opening the vent, so that the heat energy in the cabinet 1 can be discharged from the vent;

[0049] If the temperature of cabinet 1 is at a high temperature for a long time, the camera transmits the image of cabinet 1;

[0050] When the temperature in the cabinet 1 is lower than the specified threshold, the temperature monitor 6 immediately sends a closing signal to the controller 1, so that the heat sink 13 moves into the frame 14, and the vent is sealed by the mutual cooperation of the sealing gasket 15;

[0051] At the same time, the temperature monitor 6 immediately sends a signal to the controller 2, and the controller 2 sends an opening command to the heater 5. The heat energy discharged by the heater 5 makes the temperature in the cabinet 1 within the specified value;

[0052] The heat energy of the cabinet 1 is discharged through the heat dissipation pipe 3 , and the heat energy in the heat dissipation pipe 3 is discharged through the heat dissipation hole 4 . When the heat energy flows in the heat dissipation hole 4 , the snow and ice on the interception plate 2 can be melted.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
