[0004] The above solution can detect the temperature and humidity inside the distribution cabinet in a timely manner through temperature and humidity control switches, and control the operation of the fan and heating resistance wire to adjust the temperature and humidity inside the distribution cabinet in a timely manner. The cabinet feet at the bottom are adjustable, which facilitates cabinet adjustment and is conducive to the stability and balance of the cabinet. The LED lights on the top of the distribution room facilitate maintenance personnel to carry out maintenance. However, the above solution has the problem of difficulty in sealing the distribution cabinet and cabinet door during operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a moisture-proof and dehumidifying smart grid energy-saving distribution cabinet, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a moisture-proof and dehumidifying smart grid energy-saving distribution cabinet, which includes a cabinet body, a closed door installed on the cabinet body, a door handle installed on the closed door, electrical equipment installed inside the cabinet body, and a temperature and humidity sensor installed on the electrical equipment. The moisture-proof and dehumidifying smart grid energy-saving distribution cabinet further includes a sealing device installed on the cabinet body. The sealing device includes a sealing mechanism for sealing the cabinet and the closed door when the moisture-proof and dehumidifying smart grid energy-saving distribution cabinet is working, and a linkage mechanism for moving the sealing mechanism to perform sealing work during operation. The sealing mechanism includes a sealing strip that is slidably installed inside the cabinet and a second inclined block that is fixedly installed on the sealing strip. The movement of the second inclined block causes the sealing strip to move in the same direction. When the sealing strip moves and contacts the closed door, it can effectively prevent external moisture and water vapor from entering the inside of the distribution cabinet.

[0007] The linkage mechanism includes a rotating column fixedly installed on the door handle, a gear fixedly installed on the circumferential surface of the rotating column, a fork rod slidably installed on the closed door, a rack fixedly installed on the fork rod, two partition blocks fixedly installed on the closed door, a spacer rod fixedly installed between the two partition blocks, a sliding plate slidably installed on the circumferential surface of the spacer rod, a connecting plate fixedly installed on the sliding plate, a long plate fixedly installed on the connecting plate, and an inclined block fixedly installed on the long plate. By setting up the linkage mechanism, it is ensured that the sealing mechanism can work normally during operation.

[0008] The fork and the inclined block are both inclined, the gear meshes with the rack, and a spring is provided between the slide and the partition block. The inclined surfaces ensure that the fork can smoothly push the inclined block when it moves, and the meshing ensures that the gear can drive the rack to move when it rotates.

[0009] The sides of the long plate and the inclined block 2 that are close to each other are both set as inclined surfaces. A spring 2 is provided between the sealing strip and the cabinet. The inclined surfaces ensure that the long plate can smoothly push the inclined block 2 when it moves, and the spring 2 ensures that the sealing strip can achieve self-reset.

[0010] The moisture-proof and dehumidifying smart grid energy-saving distribution cabinet also includes: a dehumidification device installed on the cabinet body; The dehumidification device includes a dehumidification mechanism for dehumidifying and absorbing the gas entering the cabinet body when the moisture-proof and dehumidification smart grid energy-saving distribution cabinet is working, and a locking mechanism for restricting the dehumidification mechanism when the moisture-proof and dehumidification smart grid energy-saving distribution cabinet is working. By setting up a dehumidification mechanism and a locking mechanism, it is ensured that the locking mechanism can effectively fix the dehumidification mechanism during operation, thus ensuring stable operation. The dehumidification mechanism includes a guide rail fixedly installed on the cabinet, an absorption box slidably installed on the guide rail, and a handle fixedly installed on the absorption box. The absorption box is installed inside the cabinet by the staff through the guide rail. The absorption box absorbs and purifies the air that enters the cabinet through the air inlet, and can filter out suspended dust, particulate matter and other particles in the air, keeping the environment inside the cabinet clean.

[0011] The locking device includes a limiting plate fixedly installed on the absorption box, an elastic telescopic rod fixedly installed on the cabinet, a limiting block fixedly installed on the movable end of the elastic telescopic rod, a three-sided inclined block fixedly installed on the circumferential surface of the movable end of the elastic telescopic rod, and a three-sided inclined rod fixedly installed on the sealing strip. As the sealing strip moves to close the gap between the cabinet and the door, it simultaneously moves the three-sided inclined rod. The three-sided inclined rod then contacts the three-sided inclined block and pushes it to move. The movement of the three-sided inclined block causes the movable end of the elastic telescopic rod to move in the same direction. The movement of the movable end of the elastic telescopic rod causes the limiting block to move synchronously. The limiting block contacts the limiting plate and extends into the limiting plate, thus restricting its movement relative to the absorption box.

[0012] The inclined rod and the inclined block three are both set as inclined surfaces on their respective contact surfaces. The absorption box is in contact with the cabinet. The inclined surfaces ensure that the inclined rod can smoothly push the inclined block three when it moves. The contact surfaces ensure that the absorption box can accurately absorb.

[0013] The moisture-proof and dehumidifying smart grid energy-saving distribution cabinet also includes: a ventilation device installed on the cabinet body; The ventilation device includes a heat dissipation mechanism for ventilating and cooling the power distribution cabinet when it is working, and a sealing mechanism for sealing the air outlet when the power distribution cabinet is not working. The heat dissipation mechanism includes a ventilation duct fixedly installed on the cabinet, a fixing plate fixedly installed on the ventilation duct, a servo motor fixedly installed on the fixing plate, and fan blades fixedly installed on the output end of the servo motor. When the power distribution cabinet starts working, the servo motor starts working synchronously. The servo motor drives the fan blades to start rotating. The rotating fan blades blow air out of the cabinet through the ventilation duct, creating a negative pressure inside the cabinet. Then, fresh air from outside the cabinet enters the cabinet through the air inlet, thus circulating and removing the heat generated inside the cabinet.

[0014] The enclosure mechanism includes a fixed grille fixedly installed on the cabinet, an extension plate slidably installed on the cabinet, a movable grille fixedly installed on the extension plate, a triangular block fixedly installed on the extension plate, and a long rod fixedly installed on the circumferential surface of the movable end of the elastic telescopic rod. When the movable end of the elastic telescopic rod moves, it drives the limiting block to move synchronously. At the same time, the movable end of the elastic telescopic rod drives the long rod to start moving in the same direction. The long rod moves and contacts the triangular block and pushes it to start moving. When the triangular block moves, it drives the extension plate to start moving in the same direction. The movement of the extension plate drives the movable grille to start moving. The movement of the movable grille opens the ventilation channel between it and the fixed grille.

[0015] The sides of the long rod that contact the triangular block are all set as bevels. The movable grille contacts the fixed grille. A spring is set between the movable grille and the cabinet. The bevels ensure that the long rod can smoothly push the triangular block when it moves. The contact ensures that the movable grille can close the air outlet with the fixed grille when it moves. The spring ensures that the movable grille can achieve self-reset.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, by moving the sealing strip to contact the closed door, it can effectively prevent external moisture and water vapor from entering the distribution cabinet, thereby reducing the risk of corrosion and short circuits of electrical components caused by humid environments. The sealing strip can increase the waterproof level of the distribution cabinet, improve the operational stability of the equipment in rainy or humid environments, and at the same time prevent dust, dirt and other pollutants from seeping into the distribution cabinet, keeping the internal environment clean, thereby reducing the risk of potential electrical failures, reducing the wear and tear and failure probability of the equipment, extending its service life, and improving the airtightness of the cabinet, making it difficult for internal moisture to escape and external moisture to enter, reducing the working pressure of the dehumidification module and saving energy.

[0017] 2. In this invention, the absorption box absorbs moisture, helping to reduce humidity inside the cabinet, thereby preventing malfunctions caused by high humidity, improving the stability of the power system, and allowing for better air circulation, preventing localized heat buildup and aiding in equipment cooling. A limiting block extends into the limiting plate to restrict its movement from the absorption box, ensuring that the absorption box does not shift due to external forces or vibrations during operation. This helps maintain equipment stability, extends its service life, and ensures correct positioning of the absorption box, maximizing its contact area with the environment, optimizing its moisture absorption performance, and improving air humidity control, thus keeping the inside of the distribution cabinet dry.

[0018] 3. In this invention, the rotating fan blades blow air outward through the ventilation duct, creating negative pressure inside the cabinet. Fresh air from outside then enters the cabinet through the air inlet, circulating and carrying away heat generated inside the cabinet, lowering the equipment's operating temperature and preventing damage or malfunctions caused by overheating. Simultaneously, it accelerates airflow within the cabinet, aiding in moisture evaporation and reducing humidity buildup. This is crucial for effective moisture control and dehumidification, especially in high-humidity environments. The movable grille, after resetting, works in conjunction with the fixed grille to close the ventilation channel, effectively controlling airflow and regulating the airflow inside the distribution cabinet. This prevents external airflow from affecting the equipment's condition during maintenance, maintaining a stable internal environment. It also allows for better control of the temperature and humidity inside the distribution cabinet, particularly during dehumidification, preventing external environmental interference and enhancing the effectiveness of the dehumidification equipment.

[0021] 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.

[0022] Please see Figures 1-4One embodiment of the present invention is: a moisture-proof and dehumidifying smart grid energy-saving distribution cabinet, which includes a cabinet body 1, a closed door 2 installed on the cabinet body 1, a door handle 3 installed on the closed door 2, an electrical device 4 installed inside the cabinet body 1, and a temperature and humidity sensor 5 installed on the electrical device 4. The moisture-proof and dehumidifying smart grid energy-saving distribution cabinet also includes: a sealing device installed on the cabinet body 1. The sealing device includes a sealing mechanism for sealing the cabinet 1 and the closed door 2 when the moisture-proof and dehumidifying smart grid energy-saving distribution cabinet is working, and a linkage mechanism for moving the sealing mechanism to perform sealing work during operation. The sealing mechanism includes a sealing strip 16 slidably installed inside the cabinet 1 and a beveled block 17 fixedly installed on the sealing strip 16. By moving the sealing strip 16 to contact the closed door 2, it can effectively prevent external moisture and water vapor from entering the distribution cabinet, thereby reducing the risk of corrosion and short circuit of electrical components caused by the humid environment. The sealing strip 16 can increase the waterproof level of the distribution cabinet, improve the operational stability of the equipment in rainy or humid environments, and prevent dust, dirt and other pollutants from seeping into the distribution cabinet, keeping the internal environment clean, thereby reducing the risk of potential electrical failures, reducing the wear and failure probability of the equipment, and extending its service life. In addition, the improved airtightness of the cabinet 1 makes it difficult for internal moisture to escape and external moisture to enter, reducing the working pressure of the dehumidification module and saving energy.

[0023] The linkage mechanism includes a rotating column 6 fixedly installed on the door handle 3, a gear 7 fixedly installed on the circumferential surface of the rotating column 6, a fork 9 slidably installed on the closed door 2, a rack 8 fixedly installed on the fork 9, two partition blocks 10 fixedly installed on the closed door 2, a spacer 11 fixedly installed between the two partition blocks 10, a sliding plate 12 slidably installed on the circumferential surface of the spacer 11, a connecting plate 13 fixedly installed on the sliding plate 12, a long plate 14 fixedly installed on the connecting plate 13, and an inclined block 15 fixedly installed on the long plate 14. By setting up the linkage mechanism, it is ensured that the sealing mechanism can work normally during operation.

[0024] The surfaces of the fork 9 and the inclined block 15 that come into contact with each other are both set as inclined surfaces. The gear 7 meshes with the rack 8. A spring is set between the slide plate 12 and the partition block 10. By setting the inclined surfaces, it is ensured that the fork 9 can smoothly push the inclined block 15 when moving. By setting the meshing, it is ensured that the gear 7 can drive the rack 8 to move when rotating.

[0025] The sides of the long plate 14 and the inclined block 17 that are close to each other are both set as inclined surfaces. A spring is set between the sealing strip 16 and the cabinet 1. By setting the inclined surfaces, it is ensured that the long plate 14 can smoothly push the inclined block 17 when it moves. By setting the spring, it is ensured that the sealing strip 16 can achieve self-reset.

[0026] In this embodiment, before the moisture-proof and dehumidifying smart grid energy-saving distribution cabinet starts working, professional personnel need to inspect the entire distribution cabinet. After the personnel have completed the inspection and confirmed that everything is correct, they connect the tested distribution cabinet to the circuit. Then, the power equipment 4 installed inside the cabinet 1 distributes the power entering it to each power branch and other equipment in a reasonable manner to achieve centralized power supply management. At this time, the temperature and humidity sensor 5 installed inside the cabinet 1 starts working to monitor the internal environment of the cabinet 1 in real time. When the humidity is detected to be too high and condensation is likely to occur, the temperature and humidity sensor 5 controls the exhaust fan to expel the high humidity gas inside the cabinet 1 in time, reduce the air humidity, and prevent the lines and switching equipment from being damp, corroded, or short-circuited. After the staff has finished debugging the entire distribution cabinet and closed the closed door 2 of cabinet 1, the staff turns the door handle 3 on the closed door 2 to close the closed door 2. When the door handle 3 turns, it drives the rotating column 6 to start rotating synchronously. The rotating column 6 drives the gear 7 to start rotating synchronously. When the gear 7 rotates, it drives the rack 8 to start moving. The movement of the rack 8 drives the fork 9 to start moving in the same direction. The movement of the fork 9 contacts the inclined block 15 and pushes it to start moving. When the inclined block 15 moves, it drives the long plate 14 to start moving in the same direction. The movement of the long plate 14 drives the connecting plate 13 to move in the same direction and contact the inclined block 17. The movement of the connecting plate 13 drives the sliding plate 12 to start moving synchronously along the extension direction of the spacer 11. The movement of the sliding plate 12 compresses the spring 1 between it and the spacer block 10. The movable contact inclined block 17 is pushed to start moving. The movement of inclined block 17 causes the sealing strip 16 to move in the same direction. The sealing strip 16 moves and contacts the closed door 2, which can effectively prevent external moisture and water vapor from entering the power distribution cabinet. This reduces the risk of corrosion and short circuit of electrical components caused by the humid environment. The sealing strip 16 can increase the waterproof level of the power distribution cabinet and improve the operational stability of the equipment in rainy or humid environments. At the same time, it can prevent dust, dirt and other pollutants from penetrating into the power distribution cabinet, keeping the internal environment clean, thereby reducing the risk of potential electrical failures, reducing the wear and failure probability of the equipment, and extending its service life. In addition, the airtightness of the cabinet 1 is improved, making it difficult for internal moisture to escape and external moisture to enter, reducing the working pressure of the dehumidification module and saving energy.

[0027] Please see Figures 5-8 Based on the above embodiments, in another embodiment of the present invention, the moisture-proof and dehumidifying smart grid energy-saving distribution cabinet further includes: a dehumidifying device installed on the cabinet 1; The dehumidification device includes a dehumidification mechanism for dehumidifying and absorbing the gas entering the cabinet 1 when the moisture-proof and dehumidification smart grid energy-saving distribution cabinet is working, and a locking mechanism for restricting the dehumidification mechanism when the moisture-proof and dehumidification smart grid energy-saving distribution cabinet is working; By setting up a dehumidification mechanism and a locking mechanism, it is ensured that the locking mechanism can effectively fix the dehumidification mechanism during operation, thus ensuring stable operation. The dehumidification mechanism includes a guide rail 181 fixedly installed on the cabinet 1, an absorption box 182 slidably installed on the guide rail 181, and a handle 183 fixedly installed on the absorption box 182. The absorption box 182 can absorb moisture, help reduce the humidity inside the cabinet, thereby preventing malfunctions caused by high humidity, improving the stability of the power system, and allowing the purified air to circulate better, avoiding local heat accumulation and helping to cool the equipment.

[0028] The locking device includes a limiting plate 184 fixedly installed on the absorption box 182, an elastic telescopic rod 185 fixedly installed on the cabinet 1, a limiting block 186 fixedly installed on the movable end of the elastic telescopic rod 185, a beveled block 187 fixedly installed on the circumferential surface of the movable end of the elastic telescopic rod 185, and a beveled rod 188 fixedly installed on the sealing strip 16. The limiting block 186 extends into the limiting plate 184 to restrict its movement relative to the absorption box 182, ensuring that the absorption box 182 will not shift due to external force or vibration during operation. This helps maintain the stability of the equipment, extends its service life, and ensures the correct positioning of the absorption box 182, maximizing its contact area with the environment, optimizing its moisture absorption performance, and improving the control of air humidity, thereby keeping the inside of the distribution cabinet dry.

[0029] The sides of the inclined rod 188 and the inclined block 187 that come into contact with each other are both set as inclined surfaces. The absorption box 182 contacts the cabinet 1. By setting the inclined surfaces, it is ensured that the inclined rod 188 can smoothly push the inclined block 187 when it moves. By setting the contact, it is ensured that the absorption box 182 can accurately absorb.

[0030] The moisture-proof and dehumidifying smart grid energy-saving distribution cabinet also includes: a ventilation device installed on the cabinet 1; The ventilation device includes a heat dissipation mechanism for ventilating and cooling the power distribution cabinet when it is working, and a sealing mechanism for closing the air outlet when the power distribution cabinet is not working. The heat dissipation mechanism includes a ventilation duct 191 fixedly installed on the cabinet 1, a fixing plate 192 fixedly installed on the ventilation duct 191, a servo motor 193 fixedly installed on the fixing plate 192, and a fan blade 194 fixedly installed on the output end of the servo motor 193. When the fan blade 194 rotates, it blows air out of the cabinet 1 through the ventilation duct 191, creating a negative pressure inside the cabinet 1. Then, fresh air from outside the cabinet 1 enters the cabinet 1 through the air inlet, thus circulating and removing the heat generated inside the cabinet 1, reducing the operating temperature of the equipment, thereby preventing damage or malfunction caused by overheating. At the same time, it accelerates the airflow inside the cabinet, helps moisture evaporate, and reduces moisture accumulation. This is very important for the effect of moisture prevention and dehumidification, especially in high humidity environments.

[0031] The enclosure mechanism includes a fixed grille 195 fixedly installed on the cabinet 1, an extension plate 197 slidably installed on the cabinet 1, a movable grille 196 fixedly installed on the extension plate 197, a triangular block 198 fixedly installed on the extension plate 197, and a long rod 199 fixedly installed on the circumferential surface of the movable end of the elastic telescopic rod 185. After the movable grille 196 is reset, it cooperates with the fixed grille 195 to close the ventilation channel, effectively controlling the airflow. This helps to regulate the airflow inside the distribution cabinet, ensuring that the equipment status is not affected by external airflow during maintenance, maintaining the stability of the cabinet environment, and better controlling the temperature and humidity inside the distribution cabinet. Especially during dehumidification, it avoids interference from the external environment with the cabinet conditions and improves the effectiveness of the dehumidification equipment.

[0032] The sides of the long rod 199 and the triangular block 198 that come into contact with each other are both set as bevels. The movable grille 196 contacts the fixed grille 195. A spring is set between the movable grille 196 and the cabinet 1. The bevels ensure that the long rod 199 can smoothly push the triangular block 198 when it moves. The contact ensures that the movable grille 196 can close the air outlet with the fixed grille 195 when it moves. The spring ensures that the movable grille 196 can achieve self-reset.

[0033] In this embodiment, after the staff has completed the inspection of the entire distribution cabinet, the staff installs the absorption box 182 inside the cabinet 1 via the guide rail 181. The absorption box 182 absorbs and purifies the air entering the cabinet 1 through the air inlet, filtering out suspended dust, particulate matter, etc., keeping the cabinet environment clean and reducing the impact of pollution on electrical components. At the same time, the absorption box 182 can absorb moisture, helping to reduce the humidity inside the cabinet, thereby preventing malfunctions caused by high humidity, improving the stability of the power system, and the purified air can circulate better, avoiding local heat accumulation and helping to cool the equipment. As the sealing strip 16 moves to fill the gap between the enclosed cabinet 1 and the enclosed door 2, it simultaneously moves the inclined rod 188. The inclined rod 188 moves and contacts the inclined block 187, pushing it to move. The movement of the inclined block 187 causes the movable end of the elastic telescopic rod 185 to move in the same direction. The movement of the movable end of the elastic telescopic rod 185 causes the limiting block 186 to move synchronously. The limiting block 186 moves and contacts the limiting plate 184 and extends into the limiting plate 184. The limiting block 186 extends into the limiting plate 184 to restrict its contact with the absorption box 182, ensuring that the absorption box 182 will not be displaced due to external force or vibration during operation. This helps maintain the stability of the equipment, extends its service life, and ensures that the absorption box 182 is correctly positioned, maximizing its contact area with the environment, optimizing its moisture absorption performance, and improving the control effect of air humidity, thereby keeping the inside of the distribution cabinet dry.

[0034] Simultaneously with the start of operation of the distribution cabinet, servo motor 193 starts working, driving fan blade 194 to rotate. The rotating fan blade 194 blows air out of the cabinet 1 through ventilation duct 191, creating negative pressure inside the cabinet 1. Fresh air from outside then enters the cabinet 1 through the air inlet, thus circulating and removing heat generated inside the cabinet 1, lowering the equipment's operating temperature and preventing damage or malfunctions caused by overheating. Simultaneously, it accelerates airflow inside the cabinet, aiding in moisture evaporation and reducing humidity accumulation. This is crucial for effective moisture control and dehumidification, especially in high-humidity environments. As the movable end of the elastic telescopic rod 185 moves, it simultaneously moves the limiting block 186, and the movable end of the elastic telescopic rod 185 drives the long rod 199 to move in the same direction. The long rod 199 then contacts the triangular block 198. And push it to start moving. When the triangular block 198 moves, it drives the extension plate 197 to move in the same direction. The movement of the extension plate 197 drives the moving grille 196 to move. The moving grille 196 opens the ventilation channel between itself and the fixed grille 195. When the staff opens the closed door 2 for maintenance work, the moving grille 196 begins to move and reset under the action of the elastic three. After the moving grille 196 resets, it cooperates with the fixed grille 195 to close the ventilation channel, effectively controlling the air flow. This can help regulate the airflow inside the distribution cabinet, so that the equipment status will not be affected by the external airflow during maintenance, maintaining the stability of the cabinet environment. At the same time, it can better control the temperature and humidity inside the distribution cabinet, especially during the dehumidification process, avoiding interference from the external environment on the cabinet conditions and improving the effect of the dehumidification equipment.
