[0032] Embodiment 1

[0033] like Figure 1-3 As shown, the utility model provides a high-pressure central cabinet with a dehumidification function, including a cabinet body 1, a mounting cavity 101 is opened in the cabinet body 1, a dehumidifier 2 installed on one side of the cabinet body 1, and a regeneration component arranged in the dehumidifier 2; the dehumidifier 2 includes an air inlet pipe 201, a dehumidification filter 202 and a dehumidification fan 203, the dehumidification filter 202 is fixedly connected to the dehumidifier 2, the dehumidification filter 202 is made of activated carbon, one end of the air inlet pipe 201 is connected to the mounting cavity 101, and the other end is connected to the dehumidification filter 202, the air outlet of the dehumidification fan 203 is connected to the mounting cavity 101, and the air inlet is arranged on the dehumidification filter. A dehumidifier 2 is arranged above the net 202, so that the dehumidification fan 203 can draw the air in the installation cavity 101 into the air intake duct 201 from the air intake duct 201, and then the air in the air intake duct 201 will be filtered by the dehumidification filter 202. When the air passes through the dehumidification filter 202, the dehumidification filter 202 will absorb moisture and other pollutants in the air through a large number of tiny holes and micropores on its surface, thereby achieving the effect of dehumidification and filtration, so that the air discharged into the installation cavity 101 by the dehumidification fan 203 again is fresh and dry, thereby achieving the purpose of dehumidifying the air in the installation cavity 101.

[0034] In order to avoid the need for frequent replacement of the filter, the regeneration component includes a partition that symmetrically divides the dehumidification filter 202. The other end of the air intake duct 201 is connected to half of the dehumidification filter 202. A motor 4 is fixedly installed on the top surface of the dehumidifier 2, and an output shaft 401 is fixedly connected to the motor 4. The output shaft 401 is fixedly connected to the center of the top surface of the partition, so that only half of the dehumidification filter 202 will be used for a single filtration and dehumidification, and the other half of the dehumidification filter 202 will be dried aside. After half of the filter absorbs a large amount of moisture, the dehumidification filter 202 can be driven to rotate by starting the motor 4, and the half-zone position of the filter can be swapped to achieve the recycling of the filter.

[0035] In order to prevent rain from wetting the motor 4 and causing damage to the motor 4, a protective cover 402 is provided on the outside of the motor 4, so that when it rains, the top of the protective cover 402 can separate the rain from the motor 4, thereby protecting the motor 4 and preventing it from being damaged by a short circuit due to water ingress. The top edge of the protective cover 402 is wider than the side of the protective cover 402, and a plurality of heat dissipation holes 403 are provided at equal intervals in a linear array on the front and back surfaces of the protective cover 402, so that the edge of the protective cover 402 can guide rainwater to fall to the outside of the heat dissipation holes 403, so that the motor 4 can also dissipate heat through the heat dissipation holes 403 when it rains, thereby protecting the motor 4 while alleviating the heat generation phenomenon during the operation of the motor 4.

[0036] In order to facilitate the staff to observe the situation in the installation cavity 101, one end of the protective door 102 is hinged on the front of the cabinet 1, and a transparent observation window is provided at the upper end of the protective door 102, so that the staff can view the situation in the installation cavity 101 through the observation window on the protective door 102 at the front of the cabinet 1, so as to facilitate the staff to observe the status of the equipment in the installation cavity 101 for inspection and maintenance. An L-shaped handle is provided on the other end of the protective door 102. By providing the handle, the staff can open and close the protective door 102 by holding the handle, thereby making it more convenient for the staff to apply force when opening and closing the protective door 102.

[0037] In order to keep the bottom surface of the device dry, a plurality of columns 5 are provided on the bottom surface of the installation cavity 101. A raising plate 501 is connected to the top of the column 5. The raising plate 501 is higher than the connection point between the air inlet duct 201 and the installation cavity 101. A plurality of air inlet holes 502 are provided on the raising plate 501 in a linear array at equal intervals, so that the bottom surface of the device is no longer in direct contact with the installation cavity 101, but is above the raising plate 501. Because the air inlet holes 502 are provided on the raising plate 501, the bottom surface of the device is suspended in the air, thereby greatly enhancing the air circulation of the bottom surface, so that the bottom surface of the device will not be damaged due to close contact with the bottom surface of the installation cavity 101 and excessive moisture.

[0038] Embodiment 2

[0039] Based on the first embodiment, specifically, Figure 1-3 As shown, in order to speed up the regeneration speed of the dehumidification filter 202, the regeneration component also includes a regeneration fan 3, which is fixedly installed on the inner bottom surface of the dehumidifier 2, and the air inlet of the regeneration fan 3 is arranged on the bottom surface of the dehumidifier 2, and the air outlet of the regeneration fan 3 and the other half of the dehumidification filter 202 are connected through an exhaust duct 303, and a heating block 301 is arranged between the regeneration fan 3 and the other half of the dehumidifier 2, and an exhaust channel 302 adapted thereto is arranged above the other half of the dehumidifier 2, and the other end of the exhaust channel 302 is connected to the side of the dehumidifier 2. By arranging the heating block 301, the exhaust channel 302, and the exhaust duct 303, the dehumidification filter in a humid state can be regenerated. When filtering 202, the regeneration fan 3 can be started to blow air into the dehumidification filter 202 through the exhaust duct 303, and then the heating block 301 heats the wind before blowing it to the dehumidification filter 202, so that the hot air continues to dry the dehumidification filter 202, and the exhaust channel 302 at the top of the dehumidification filter 202 can prevent the humid and hot gas from escaping and polluting the dry air that is about to be sent into the installation cavity 101, and a rainproof canopy 304 is provided on the other end of the exhaust channel 302, so that when it rains, the rainproof canopy 304 can block rainwater from falling into the exhaust channel 302, and then dripping on the dehumidification filter 202, and wetting the dehumidification filter 202.

[0040] Working principle:

[0041] When in use, first pull the handle to open the installation cavity 101, then install the device on the padding plate 501 and close the protective door 102, and the installation of the device is completed.

[0042] When dehumidification is performed, the dehumidification fan 203 can be started to draw air into the dehumidifier 2 from the air inlet duct 201. The air is transported through the air inlet duct 201 to the bottom of one half of the dehumidification filter 202. After passing through the dehumidification filter 202, the air is re-discharged into the installation cavity 101 by the dehumidification fan 203, thereby completing the dehumidification operation.

[0043] When the dehumidification filter 202 is regenerated, the output shaft 401 can be driven to rotate by starting the motor 4, and the wet half of the dehumidification filter 202 can be turned to the bottom of the exhaust channel 302. The regeneration fan 3 is started to blow the air heated by the heating block 301 to the wet half of the dehumidification filter 202 through the exhaust duct 303, so as to dry the wet half of the dehumidification filter 202. After the hot air takes away the moisture on the dehumidification filter 202, it will be discharged from the dehumidifier 2 through the exhaust channel 302. After the wet dehumidification filter 202 is dried, the other half of the dehumidification filter 202 that has been turned and moistened can be turned back for drying again, so that the dehumidification filter 202 can be used repeatedly without frequent replacement, saving property and manpower losses during later maintenance.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
