The dehumidification device is connected to the temperature and humidity sensors.

[0008] According to the above technical solution, a filter screen is provided on the outside of the air intake fan, and cleaning bristles are provided on the outside of the air intake fan blades.

[0009] According to the above technical solution, the lower half of the cabinet is equipped with a power cabinet protection device. The power cabinet protection device includes an airbag chamber, a rotating rod, a leakage current sensor, and a fire extinguisher. The airbag chamber is located at the bottom of the cabinet. An airbag chamber door is located on the side of the airbag chamber closest to the outer wall of the cabinet, and a latch is provided between the airbag chamber door and the cabinet body. An emergency airbag is installed inside the airbag chamber. A slider chamber is located at the bottom of the airbag chamber. An airbag button is located on the inner rear wall of the slider chamber, and the airbag button is connected to the circuit breaker and the fire extinguisher. The inner wall of the compartment near the cabinet body is movably connected to the triangular slider via a spring. The second rotating rod is rotatably installed on the top edge of the cabinet body. A support plate is fixedly installed on the outer wall of the second rotating rod. The bottom of the support plate is fixedly connected to one end of the support spring, and the other end of the support spring is fixedly connected to the front outer wall of the cabinet body. The leakage current sensor is fixedly installed on the rear inner wall of the cabinet body. A circuit breaker is fixedly installed above the leakage current sensor, and the rear outer wall of the circuit breaker is fixedly connected to the rear inner wall of the cabinet body. The fire extinguisher is fixedly installed on the upper half of the left inner wall of the cabinet body.

[0010] According to the above technical solution, a rainproof and ventilation device is provided on the top of the cabinet. The rainproof and ventilation device includes a ventilation hole and a hollow column. The ventilation hole is opened on the top of the cabinet and a ventilation fan is installed inside the ventilation hole. The hollow column is fixedly installed on the top of the cabinet. A support column is slidably installed inside the hollow column. A spring is provided between the bottom of the support column and the bottom inner wall of the hollow column. A rainproof plate is fixedly connected to the top of the support column. A groove is opened in the middle of the rainproof plate. Rainproof sheets are rotatably connected to all four sides of the rainproof plate, and a torsion spring is provided at the connection between the rainproof sheets and the rainproof plate.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) This invention, through the setting of a dehumidification device, allows the intake fan and filter screen to work together to filter out dust and foreign objects in the air, ensuring the cleanliness of the cabinet interior; through the cooperation of the intake fan, heat-conducting plate, heating tube, exhaust fan and air outlet, heated air enters the cabinet interior from above, forcing the moisture inside the cabinet downwards by the hot air, and causing the moisture to leave through the downward-sloping air outlet in the lower half of the cabinet, preventing the equipment and wiring inside the cabinet from getting damp and improving the safety of the equipment; through the cooperation of the intake fan, heat-conducting plate, heating tube, exhaust fan, air outlet and temperature and humidity sensor, when the humidity inside the cabinet is too high, the heating tube increases the temperature and the intake fan accelerates its operation, when the humidity inside the cabinet is too high, the temperature is reduced and the humidity is reduced. When the temperature is too high, the heating element stops heating, and the exhaust fan reduces its speed to ensure that the temperature and humidity inside the cabinet are within a certain range. This allows the equipment to operate at a suitable temperature, improving its stability and extending the lifespan of the equipment and wiring. Through the cooperation of the rain cover, rotating rod, spring, and exhaust fan, the rain cover reduces the probability of dust and foreign objects entering the exhaust fan, ensuring its operating efficiency. During heavy rain, the spring under the rain cover contracts under the impact, significantly expanding the area covered by the rain cover to prevent rainwater and foreign objects from entering the exhaust fan and ensuring that the exhaust fan is not affected. When the weather returns to calm, the spring pushes the rain cover back to its original position, expanding the exhaust fan's suction range.

[0012] (2) The present invention improves the stability of the cabinet by setting up a power cabinet protection device, which allows the triangular slider and spring to cooperate. The triangular slider, slider chamber, airbag button, emergency airbag, airbag chamber, support plate, support spring and rotating rod cooperate to prevent the cabinet from falling when it is impacted by external force. The emergency airbag inflates and pops out to block the cabinet in front of the cabinet and prevent the cabinet from being damaged, thus reducing the damage to the machine. At the same time, when the top of the cabinet hits the ground, the support plate reduces the impact force of the cabinet through the spring and keeps the cabinet in a relatively stable state together with the emergency airbag, reducing the impact damage to the internal equipment and wiring of the cabinet. The support plate provides a certain degree of rain protection, sun protection and dust protection for the cabinet and cabinet door, prolongs the life of the cabinet and prevents the cabinet from being affected by too much external influence, thus preventing premature aging and damage.

[0013] (3) The present invention enables the airbag button, circuit breaker and fire extinguisher to work together by setting the leakage current sensor. When the airbag button is triggered, the circuit breaker trips and cuts off the power supply to the equipment. The fire extinguisher sprays carbon dioxide to extinguish the sparks generated by the broken circuit due to the impact, preventing the equipment in the cabinet from causing greater damage due to the impact. By working together with the leakage current sensor, circuit breaker and fire extinguisher, the leakage current sensor can monitor in real time whether the equipment in the cabinet has leakage current during the daily operation of the power cabinet. When leakage current occurs, the leakage current sensor will control the circuit breaker to trip in time. When the equipment has a serious problem that causes a fire, the leakage current sensor will control the circuit breaker to trip in time and at the same time activate the fire extinguisher to extinguish the fire, ensuring that the problem in the substation cabinet can be contained in time and will not cause a chain reaction that affects the surrounding environment and people.

[0014] (4) The present invention, through the setting of the rainproof ventilation device, enables the ventilation hole, ventilation fan, rainproof plate and rainproof sheet to cooperate, so that the ventilation fan can ensure the air circulation inside the cabinet, while the rainproof plate and rainproof sheet can also block the sunlight and foreign objects above the ventilation fan, keep the inside of the cabinet clean and reduce the damage of sun exposure to the cabinet; through the cooperation of the rainproof plate, rainproof sheet and torsion spring, in the event of strong wind, the rainproof sheet around the rainproof plate will rotate inward under the wind, forming a four-sided windproof wall to prevent dust from entering the inside of the cabinet through the ventilation hole and ensure the cleanliness of the inside of the cabinet; through the cooperation of the rainproof plate, support column, spring and hollow column, in the event of heavy rain, the groove in the middle of the rainproof plate will collect rainwater. When the rainwater in the groove reaches a certain level, the support column will drive the rainproof plate to descend through the spring, so that the groove in the center of the rainproof plate will block the ventilation hole, preventing rainwater from entering the inside of the cabinet through the ventilation hole and damaging the equipment and wiring inside the cabinet, thus improving the safety of the equipment.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-8The present invention provides a technical solution: a moisture-proof power cabinet, including a cabinet body 1, a cabinet door 2 rotatably installed on the front of the cabinet body 1, an equipment rack 3 fixedly installed inside the cabinet body 1, and air vents 4 fixedly installed on the lower half of the outer walls on both sides of the cabinet body 1. It also includes a dehumidification device 5, a power cabinet protection device 6, and a rainproof ventilation device 7. The power cabinet protection device 6 is located on the lower half of the cabinet body 1, the rainproof ventilation device 7 is located on the top of the cabinet body 1, and the dehumidification devices 5 are located on the left and right sides of the cabinet body 1. Each dehumidification device 5 includes a housing 51, an exhaust fan 55, and a rotating rod 56. The housing 51 is fixedly installed on the left outer wall of the cabinet body 1, and the upper half of the left outer wall of the housing 51 is provided with a suction... The air fan 52 has a filter screen on its outer side and cleaning bristles on the outer side of its blades. The filter screen removes foreign objects from the air, ensuring the cleanliness of the cabinet body 1. The cleaning bristles on the outer side of the air fan 52 clean the filter screen as it rotates, preventing clogging. The inner left side of the outer casing 51 is fixedly connected to one side of the heat-conducting plate 54, and the other side of the heat-conducting plate 54 is fixedly connected to the heating element 53. The side of the heating element 53 closest to the cabinet body 1 is fixedly connected to the outer left side of the cabinet body 1. The exhaust fan 55 is located on the left side of the cabinet body 1 and is connected to the inside of the outer casing 51. The rotating rod 56 is rotatably mounted on the cabinet. The outer wall of the left side of the cabinet 1 is connected to the top of the rain cover 57, with the rotating rod 56 located directly above the outer shell 51. A groove is provided at the contact point between the rain cover 57 and the wall of the cabinet 1. A spring is installed at the bottom left side of the rain cover 57 and the left outer wall of the cabinet 1, with the spring located within the groove. During heavy rain, the rain cover 57 is impacted by rainwater, and the spring below the rain cover 57 will contract under the impact force, causing the rain cover 57 to tilt downwards. This significantly expands the area covered by the rain cover 57 for the intake fan 52, preventing rainwater and foreign objects from entering the intake fan and ensuring that the intake fan 52 is not affected by rainwater. After the weather calms down, the spring pushes the rain cover 57 back to its original position, expanding the air intake range of the suction fan 52. Temperature and humidity sensors are fixedly installed on the inner walls of the left and right sides of the cabinet body 1. The dehumidification device 5 is connected to the temperature and humidity sensors. The temperature and humidity sensors can monitor the temperature and humidity inside the power cabinet in real time. When the humidity inside the cabinet body 1 is too high, the heating element 53 increases the temperature and the suction fan 52 accelerates its operation. When the temperature inside the cabinet body 1 is too high, the heating element 53 stops heating and the suction fan 52 reduces its speed, ensuring that the temperature and humidity inside the cabinet body 1 are within a certain range, so that the equipment operates in a suitable temperature, improving the stability of the equipment and extending the life of the equipment and lines.

[0019] The lower half of the cabinet body 1 is equipped with a power cabinet protection device 6. The power cabinet protection device 6 includes an airbag chamber 61, a rotating rod 65, a leakage current sensor 68, and a fire extinguisher 610. The airbag chamber 61 is located at the bottom of the cabinet body 1. The side of the airbag chamber 61 closest to the outer wall of the cabinet body 1 has an airbag chamber door, and a latch is provided between the airbag chamber door and the cabinet body 1, so that the emergency airbag 62 can quickly open the airbag chamber door through its own expansion, protecting the power cabinet immediately. An emergency airbag 62 is installed inside the airbag chamber 61. A slider chamber 63 is located at the bottom of the airbag chamber 61. An airbag button is located on the inner rear wall of the slider chamber 63, and the airbag button is connected to the circuit breaker 69 and the fire extinguisher 610. When the power cabinet is tilted due to external force, the triangular slider 64 will first enter the slider chamber 63 to trigger the airbag button. When the airbag button is triggered... The system will simultaneously activate the emergency airbag 62, the circuit breaker 69, and the fire extinguisher 610. The emergency airbag 62 protects the exterior of the power cabinet, while the circuit breaker 69 and the fire extinguisher 610 resolve fire and leakage issues caused by equipment inside the power cabinet. The inner wall of the slider chamber 63 near the cabinet body 1 is movably connected to the triangular slider 64 via a spring. The rotating rod 65 is rotatably installed on the top edge of the cabinet body 1. A support plate 66 is fixedly installed on the outer wall of the rotating rod 65. The bottom of the support plate 66 is fixedly connected to one end of the support spring 67, and the other end of the support spring 67 is fixedly connected to the front outer wall of the cabinet body 1. The leakage current sensor 68 is fixedly installed on the rear inner wall of the cabinet body 1. The circuit breaker 69 is fixedly installed above the leakage current sensor 68, and the rear outer wall of the circuit breaker 69 is fixedly connected to the rear inner wall of the cabinet body 1. The fire extinguisher 610 is fixedly installed on the upper half of the left inner wall of the cabinet body 1.

[0020] A rainproof and ventilation device 7 is installed on the top of the cabinet body 1. The rainproof and ventilation device 7 includes a ventilation hole 71 and a hollow column 73. The ventilation hole 71 is located on the top of the cabinet body 1, and a ventilation fan 72 is installed inside the ventilation hole 71. The hollow column 73 is fixedly installed on the top of the cabinet body 1. A support column 74 is slidably installed inside the hollow column 73. A spring is installed between the bottom of the support column 74 and the bottom inner wall of the hollow column 73, which allows the support column 74 to move inside the hollow column 73. A rainproof plate 75 is fixedly connected to the top of the support column 74. The rain shield 75 has a groove in the middle. When it rains heavily, rainwater will accumulate in the groove in the middle of the rain shield 75. When the weight of the rainwater reaches a certain level, the spring at the bottom of the support column 74 will contract under the influence of the weight. The contracted spring will drive the support column 74 and the rain shield 75 to descend, so that the groove in the middle of the rain shield 75 will block the ventilation hole 71, preventing rainwater from entering the cabinet 1 and affecting the operation of the equipment and lines. Rain shields 76 are rotatably connected around the rain shield 75, and torsion springs are provided at the connection between the rain shields 76 and the rain shield 75.

[0021] In use, place the cabinet 1 in a suitable position, open the cabinet door 2, connect the equipment and wiring to the equipment rack 3, close the cabinet door 2, and the power cabinet will operate normally. The dehumidifier 5 will start operating, and the exhaust fan 52 will draw in air. The air passes through the filter screen and enters the outer casing 51. The filter screen removes dust and foreign objects from the air. When the exhaust fan 52 rotates, the cleaning brush on the fan surface cleans the dust and foreign objects from the filter screen. Air flows through the gaps between the heat-conducting plates 54, at which point the heating element 53 begins to heat up. The heat-conducting fins 54 on the heating element 53 absorb heat, heating the flowing air. The heated air enters the cabinet 1 through the exhaust fan 55. The heated air enters the cabinet 1 from above, forcing the moisture inside the cabinet 1 downwards. The moisture exits through the downward-sloping vents 4 in the lower half of the cabinet 1, preventing the equipment and wiring inside the cabinet 1 from getting damp and improving equipment safety. A temperature and humidity sensor connected to the dehumidification device 5 can monitor the temperature and humidity inside the cabinet 1 in real time. When the humidity inside cabinet 1 is too high, the heating element 53 increases the temperature, and the suction fan 52 accelerates its operation. When the temperature inside cabinet 1 is too high, the heating element 53 stops heating, and the suction fan 52 reduces its speed, ensuring that the temperature and humidity inside cabinet 1 are within a certain range. This allows the equipment to operate at a suitable temperature, improving its stability and extending the lifespan of the equipment and wiring. The rain cover 57 above the dehumidifier 5 reduces the amount of dust and foreign objects sucked in by the suction fan 52. In severe weather conditions such as rain, snow, and strong winds, the tilted surface of the rain cover 57 is protected from... When pressed down by the impact of rain and snow, the rotating rod 56 drives the rain cover 57 to rotate. The cover wall of the rain cover 57 slides into the cabinet body 1 through the slide groove. The spring under the rain cover 57 is impacted and contracts. The spring causes the rain cover 57 to tilt downward, greatly expanding the area covered by the rain cover 57 to cover the dehumidifier 5. The rain cover 57 completely covers the air intake fan 52, preventing rain, snow and foreign objects from entering the dehumidifier 5 and preventing damage to the dehumidifier 5. When the weather returns to calm, the spring pushes the rain cover 57 back to its original position, expanding the air intake range of the dehumidifier 5.

[0022] When the power cabinet is tilted by an external force, the triangular slider 64 can improve the stability of the cabinet body 1. When the external force is large enough, the triangular slider 64 slides into the slider chamber 63, the spring behind the triangular slider 64 contracts, and the triangular slider 64 hits the airbag button. The emergency airbag 62 begins to inflate. The inflating emergency airbag 62 begins to expand rapidly, and the inflated emergency airbag 62 pushes open the airbag chamber door. The fully inflated emergency airbag 62 blocks the front of the cabinet body 1, reducing damage to the machine. When the top of the cabinet body 1 hits the ground, the support plate 66 reduces the impact force of the cabinet body 1 through the spring, and together with the emergency airbag 62, keeps the cabinet body 1 in a relatively stable state, reducing the impact damage to the internal equipment and wiring of the cabinet body 1. At the same time as the airbag button is pressed, the circuit breaker 69 trips, and the fire extinguisher 610 extinguishes the fire inside the cabinet body 1. The system sprays carbon dioxide to prevent the equipment inside cabinet 1 from being further damaged by the current. During the daily operation of the power cabinet, the support plate 66 also provides some protection against rain, sun, and dust for cabinet 1 and cabinet door 2, extending the life of cabinet 1 and preventing excessive external influences that could lead to premature aging or damage. The leakage current sensor 68 can also monitor in real time whether there is a leakage current in the equipment inside cabinet 1. In the event of a leakage current, the leakage current sensor 68 will promptly control the circuit breaker 69 to trip. In the event of a serious problem with the equipment that causes a fire, the leakage current sensor 68 will activate the fire extinguisher 610 while simultaneously controlling the circuit breaker 69 to trip, causing the fire extinguisher 610 to spray carbon dioxide to extinguish the fire. This ensures that problems inside the power cabinet can be contained immediately, preventing chain reactions that could affect the surrounding environment and people.

[0023] During the daily operation of the power cabinet, the ventilation fan 72 on top of the cabinet 1 ensures air circulation inside the cabinet 1. The rain shield 75 and rain deflector 76 above the ventilation fan 72 block sunlight and foreign objects, keeping the inside of the cabinet 1 clean and reducing damage from sun exposure. In windy weather, the rain deflector 76 around the rain shield 75 rotates inward under strong winds, forming four-sided windbreaks to prevent dust from entering the cabinet 1 through the ventilation vent 71, ensuring the cleanliness of the inside of the cabinet 1. In heavy rain, the rain shield 75... The groove in the middle of column 5 collects rainwater. When the rainwater in the groove reaches a certain level, the spring below the support column 74 will contract under the weight of the rainwater. The contracted spring will cause the support column 74 to enter the hollow column 73. As the support column 74 moves downward, it will also cause the rain shield 75 to descend. As the rain shield 75 descends, the groove in the center of the rain shield 75 also descends. The descending groove blocks the ventilation hole 71, preventing rainwater from entering the cabinet 1 and damaging the equipment and wiring inside the cabinet 1, thus improving the safety of the equipment.
