DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 9 As shown, the present invention provides a dehumidification device suitable for a power distribution cabinet, including a power distribution cabinet 100, a condensation plate 200 is fixedly installed in the power distribution cabinet 100, a connecting pipe 302 is installed through the power distribution cabinet 100, a condensation fan 300 is fixedly connected to the connecting pipe 302, the condensation fan 300 is fixedly connected to the power distribution cabinet 100, the condensation fan 300 is fixedly connected to the power distribution cabinet 100, the condensation fan 300 is fixedly connected to the air outlet pipe 301, and the power distribution cabinet 100 is fixedly connected to the air inlet pipe 303;

[0032] Among them, an extrusion baffle 400 is slidably connected in the air inlet pipe 303, the extrusion baffle 400 is fixedly connected with an absorption cotton ring 401, the absorption cotton ring 401 is fixedly connected with a fixed baffle 402, a first return spring 405 is arranged between the fixed baffle 402 and the air inlet pipe 303, a wedge-shaped extrusion block 404 is fixedly connected to the lower side of the fixed baffle 402, the wedge-shaped extrusion block 404 is wedge-shaped and slidingly connected with a wedge-shaped sliding block 403, the wedge-shaped sliding block 403 is fixedly connected to the extrusion baffle 400, the wedge-shaped sliding block 403 is slidably connected to the lower side of the air inlet pipe 303, and an extrusion tension spring 406 is arranged between the air inlet pipe 303 and the wedge-shaped sliding block 403.

[0033] The absorbent cotton ring 401 is made of water-absorbing material.

[0034] The condensation plate 200 is made of a low heat capacity material.

[0035] The diameter of the extrusion baffle 400 is the same as the inner diameter of the air inlet pipe 303 .

[0036] The above scheme is adopted: when the humidity in the air is high, the water vapor in the air will condense on the metal or wires in the distribution cabinet, which may affect the operation of electrical equipment and even cause short circuit or damage. When the water vapor condenses, it will preferentially condense on objects with lower temperatures. For this reason, a condensation plate 200 is arranged in the distribution cabinet 100. Since the condensation plate 200 is a low heat capacity material, the temperature changes faster. When the humidity in the air is high, the condensation fan 300 is started, and the cold air from the outside is drawn into the condensation plate 200 through the air inlet pipe 303 and the connecting pipe 302, and then drawn out and flows out from the air outlet pipe 301, so that the condensation plate 200 preferentially exchanges heat with the cold air, and quickly reduces the temperature of the condensation plate 200, ensuring that when the water vapor in the distribution cabinet 100 condenses, it preferentially condenses on the condensation plate 200.

[0037] Since the water vapor content in the outside air is high and water has a high heat capacity, after entering the condensation plate 200, it is easy to cause the temperature drop in the condensation plate 200 to slow down, affecting the condensation in the distribution cabinet 100. In order to prevent the outside water vapor from entering the condensation plate 200, an absorption cotton ring 401 is arranged in the air inlet pipe 303 to absorb the water vapor in the air entering the condensation plate 200. When the absorption cotton ring 401 absorbs to a certain extent, the weight of the absorption cotton ring 401 increases, thereby driving the fixed baffle 402 and the wedge-shaped extrusion block 400 to absorb the water vapor in the air. 4 slides downward, due to the wedge shape of the wedge-shaped extrusion block 404 and the wedge-shaped sliding block 403, under the pulling force of the extrusion tension spring 406, the wedge-shaped sliding block 403 slides in the direction of the absorption cotton ring 401, thereby driving the extrusion baffle 400 to slide in the same direction, and squeezing out the absorbed water in the absorption cotton ring 401. After the water is squeezed out, the weight of the absorption cotton ring 401 is restored, and it slides upward and resets under the elastic force of the first reset spring 405, thereby driving the wedge-shaped extrusion block 404 to reset the wedge-shaped sliding block 403 and the extrusion baffle 400.

[0038] like Figures 5 to 7 As shown, an air flow baffle 502 is installed in the distribution cabinet 100, and a blowing pipe 500 and an air suction pipe 501 are fixedly connected to the outside of the air flow baffle 502 respectively. The lower side of the blowing pipe 500 is connected to an exhaust pipe 503, and the lower side of the air suction pipe 501 is connected to an air suction connecting pipe 504. The lower end of the air suction connecting pipe 504 is fixedly connected to a flow fan 505, and the lower end of the flow fan 505 is fixedly connected to an air supply pipe 506.

[0039] The exhaust pipe 503 and the lower end of the gas supply pipe 506 are commonly connected to a gas compression chamber 600, and a fixed shaft 601 is fixedly connected inside the gas compression chamber 600. The fixed shaft 601 is rotatably connected to a first rotating plate 602 and a second rotating plate 603, and a first transmission spring 604 and a second transmission spring 605 are respectively arranged between the first rotating plate 602 and the second rotating plate 603. The gas compression chamber 600 is slidably connected to a limiting wedge tube 606, and a second return spring 607 is arranged between the limiting wedge tube 606 and the second return spring 607.

[0040] A limiting sliding block 611 is fixedly connected to the gas compression chamber 600, a transmission wedge tube 608 and a braking wedge tube 609 are slidingly connected through the gas compression chamber 600, the transmission wedge tube 608 and the braking wedge tube 609 are slidingly connected through the limiting sliding block 611, and a third return spring 610 is arranged between the limiting sliding block 611 and the gas compression chamber 600.

[0041] The wedge directions of the transmission wedge tube 608 and the braking wedge tube 609 are opposite, and the first rotating plate 602 and the second rotating plate 603 are in contact with the inner wall of the gas compression chamber 600 .

[0042] A pressure valve is provided between the gas compression chamber 600 and the exhaust pipe 503 .

[0043] The above scheme is adopted: when the water vapor content in the air in the distribution cabinet 100 is high, the temperature is generally not high, and the temperature within ten meters underground of the distribution cabinet 100 is slightly higher than that on the ground surface. The air in the distribution cabinet 100 is sucked into the underground through the gas compression chamber 600 arranged under the distribution cabinet 100, and then sent into the distribution cabinet 100 after the temperature is raised to a certain level, so that the temperature drop in the distribution cabinet 100 is slower than that in the outside world, which is convenient for the water vapor to condense on the condensation plate 200 more quickly, and the flow fan 505 is used to pass through the suction connecting pipe 504 and the suction pipe 50 The air in the power distribution cabinet 100 is sucked into the gas compression chamber 600 through the gas delivery pipe 506. As the air is continuously input, the air pressure in the smaller space between the first rotating plate 602 and the second rotating plate 603 increases until it breaks through the elastic force of the second return spring 607, so that the second rotating plate 603 breaks through the position of the limiting wedge tube 606 and rotates clockwise, thereby compressing the gas in the larger space between the first rotating plate 602 and the second rotating plate 603 after being heated underground, until the air pressure increases and breaks through the exhaust pipe 503 and the gas pressure chamber 606. The pressure valve between the contraction chambers 600 is transported to the distribution cabinet 100 through the exhaust pipe 503. As the gas is compressed, the temperature further increases, and the gas blown out of the blowing pipe 500 drives the water vapor in the distribution cabinet 100 to flow to the condensation plate 200. As the second rotating plate 603 continues to rotate, the second rotating plate 603 squeezes the transmission wedge tube 608 to slide outward, thereby driving the brake wedge tube 609 to slide synchronously, so that the brake wedge tube 609 unlocks the first rotating plate 602, and then under the pulling force of the first transmission spring 604, the brake wedge tube 609 is locked. The first rotating plate 602 rotates clockwise to a position where it is caught by the limiting wedge tube 606. At the same time, after the second rotating plate 603 rotates past the transmission wedge tube 608, the third return spring 610 pushes the braking wedge tube 609 to catch the second rotating plate 603 again, thereby completing a compression cycle. The cold air in the distribution cabinet 100 is sucked into the underground to increase its temperature, and then blown into the distribution cabinet 100 after being compressed, driving the water vapor to flow to the condensation plate 200, thereby increasing the temperature in the distribution cabinet 100, so that the water vapor condenses on the condensation plate 200 first.

[0044] like Figure 8 and Fig. 9As shown, a connecting air cavity 700 is provided on the condensation plate 200, and the connecting air cavity 700 is connected to the exhaust pipe 503. The connecting air cavity 700 is slidably connected to the piston shaft 703. The connecting air cavity 700 is slidably connected to the transmission shaft 704. The piston shaft 703 and the transmission shaft 704 are fixedly connected with a transmission connecting plate 707. The transmission connecting plate 707 and the connecting air cavity 700 are respectively provided with a fourth reset spring 705 or a fifth reset spring 706 on the piston shaft 703 or the transmission shaft 704. The transmission shaft 704 is fixedly connected to a cleaning roller 702, and the lower end of the cleaning roller 702 is rotatably connected to a slideway 701. An air flow hole is opened on the connecting air cavity 700 at one end close to the exhaust pipe 503.

[0045] The above scheme is adopted: the gas continuously compressed in the gas compression chamber 600 flows into the distribution cabinet 100, and at the same time flows into the connecting air chamber 700, so that the piston shaft 703 drives the transmission shaft 704 to slide in the same direction through the transmission connecting plate 707, and then the cleaning roller 702 slides on the condensation plate 200 along the slide 701, and then the condensed water vapor on the condensation plate 200 is cleaned. When a compression cycle is completed, under the action of the fourth reset spring 705 and the fifth reset spring 706, the piston shaft 703 is pushed to push the gas in the connecting air chamber 700 out of the connecting air chamber 700 through the air flow hole, so that the cleaning roller 702 is reset, waiting for the next compression cycle to drive the cleaning roller 702 to clean the surface of the condensation plate 200.

[0046] The working principle and use process of the present invention:

[0047] When the humidity in the air is high, water vapor in the air will condense on the metal or wires in the distribution cabinet, which may affect the operation of electrical equipment and even cause short circuit or damage. When water vapor condenses, it will preferentially condense on objects with lower temperatures. For this reason, a condensation plate 200 is provided in the distribution cabinet 100. Since the condensation plate 200 is made of a low heat capacity material, the temperature changes faster. When the humidity in the air is high, the condensation fan 300 is started, and the cold air from the outside is drawn into the condensation plate 200 through the air inlet pipe 303 and the connecting pipe 302, and then drawn out and flows out from the air outlet pipe 301, so that the condensation plate 200 preferentially exchanges heat with the cold air, quickly reducing the temperature of the condensation plate 200, and ensuring that when the water vapor in the distribution cabinet 100 condenses, it preferentially condenses on the condensation plate 200.

[0048] Since the water vapor content in the outside air is high and water has a high heat capacity, after entering the condensation plate 200, it is easy to cause the temperature drop in the condensation plate 200 to slow down, affecting the condensation in the distribution cabinet 100. In order to prevent the outside water vapor from entering the condensation plate 200, an absorption cotton ring 401 is arranged in the air inlet pipe 303 to absorb the water vapor in the air entering the condensation plate 200. When the absorption cotton ring 401 absorbs to a certain extent, the weight of the absorption cotton ring 401 increases, thereby driving the fixed baffle 402 and the wedge-shaped extrusion block 400 to absorb the water vapor in the air. 4 slides downward, due to the wedge shape of the wedge-shaped extrusion block 404 and the wedge-shaped sliding block 403, under the pulling force of the extrusion tension spring 406, the wedge-shaped sliding block 403 slides in the direction of the absorption cotton ring 401, thereby driving the extrusion baffle 400 to slide in the same direction, and squeezing out the absorbed water in the absorption cotton ring 401. After the water is squeezed out, the weight of the absorption cotton ring 401 is restored, and it slides upward and resets under the elastic force of the first reset spring 405, thereby driving the wedge-shaped extrusion block 404 to reset the wedge-shaped sliding block 403 and the extrusion baffle 400.

[0049] When the water vapor content in the air of the distribution cabinet 100 is high, the temperature is generally not high, and the temperature within ten meters underground of the distribution cabinet 100 is slightly higher than that on the ground surface. The air in the distribution cabinet 100 is sucked into the ground through the gas compression chamber 600 set under the distribution cabinet 100, and then sent into the distribution cabinet 100 after the temperature is raised to a certain level, so that the temperature drop in the distribution cabinet 100 is slower than that in the outside world, which is convenient for the water vapor to condense on the condensation plate 200 more quickly. The flow fan 505 passes the air suction connecting pipe 504 and the air suction pipe 501 to condense the water vapor on the condensation plate 200. The air in the air compressor 100 is sucked into the air compression chamber 600 through the air delivery pipe 506. As the air is continuously input, the air pressure in the smaller space between the first rotating plate 602 and the second rotating plate 603 increases until it breaks through the elastic force of the second return spring 607, causing the second rotating plate 603 to break through the position of the limiting wedge tube 606 and rotate clockwise, thereby compressing the air in the larger space between the first rotating plate 602 and the second rotating plate 603 that has been heated underground until the air pressure increases and breaks through the exhaust pipe 503 and the air compression chamber 606. 00, and is transported to the distribution cabinet 100 through the exhaust pipe 503. As the gas is compressed, the temperature further increases, and the gas blown out of the blowing pipe 500 drives the water vapor in the distribution cabinet 100 to flow to the condensation plate 200. As the second rotating plate 603 continues to rotate, the second rotating plate 603 squeezes the transmission wedge tube 608 to slide outward, thereby driving the brake wedge tube 609 to slide synchronously, so that the brake wedge tube 609 unlocks the first rotating plate 602, and then under the pulling force of the first transmission spring 604, the second rotating plate 603 is pressed to slide outward. A rotating plate 602 rotates clockwise to a position where it is caught by a limiting wedge tube 606. At the same time, after the second rotating plate 603 rotates past the transmission wedge tube 608, the third return spring 610 pushes the braking wedge tube 609 to catch the second rotating plate 603 again, thereby completing a compression cycle. The cold air in the distribution cabinet 100 is sucked into the underground to increase its temperature, and then blown into the distribution cabinet 100 after being compressed, driving the water vapor to flow to the condensation plate 200, thereby increasing the temperature in the distribution cabinet 100, so that the water vapor condenses on the condensation plate 200 first.

[0050] The gas continuously compressed in the gas compression chamber 600 flows into the distribution cabinet 100, and at the same time flows into the connecting air chamber 700, so that the piston shaft 703 drives the transmission shaft 704 to slide in the same direction through the transmission connecting plate 707, and then the cleaning roller 702 slides on the condensation plate 200 along the slide 701, and then cleans the condensed water vapor on the condensation plate 200. When a compression cycle is completed, under the action of the fourth reset spring 705 and the fifth reset spring 706, the piston shaft 703 is pushed to push the gas in the connecting air chamber 700 out of the connecting air chamber 700 through the air flow hole, so that the cleaning roller 702 is reset, waiting for the next compression cycle to drive the cleaning roller 702 to clean the surface of the condensation plate 200.
