DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-4 As shown, an outdoor power cabinet for preventing condensation includes a cabinet body 1, a through slot is opened on one side of the cabinet body 1, a cover shell 2 is arranged at the through slot of the cabinet body 1, a dehumidifier 3 is arranged inside the cover shell 2, the dehumidifier 3 has an air inlet port 4, an exhaust port 5 and a water outlet port 6, the air inlet port 4, the exhaust port 5 and the water outlet port 6 of the dehumidifier 3 are all located inside the cover shell 2, a drain pipe 7 is connected to the water outlet port 6 of the dehumidifier 3, one end of the drain pipe 7 passes through and extends to the outside of the cover shell 2, a vertical pole 8 is arranged at the exhaust port 5 of the dehumidifier 3, and a There is a wind shield 9, which is used to guide the gas discharged from the exhaust port 5 to one side of the cover 2. A fixed plate 10 is symmetrically arranged inside the cover 2, and a screw 11 and a guide rod 12 are arranged between the two fixed plates 10. A motor 13 for driving the screw 11 to rotate is arranged on the inner side of the cover 2. It also includes an air intake hood 14, which is threadedly connected to the screw 11, and the air intake hood 14 is slidably connected to the guide rod 12. The air intake hood 14 is connected to the air intake port 4 of the dehumidifier 3 through a folding hose 15, and a humidity sensor 16 is arranged on the dehumidifier 3.

[0018] The cover shell 2 and the cabinet body 1 can be fixed by welding or bolting. When fixed by welding, each contact position of the cover shell 2 and the cabinet body 1 needs to be welded. When fixed by bolting, a corresponding rubber layer needs to be provided between the cover shell 2 and the cabinet body 1 to ensure the airtightness of the connection between the cover shell 2 and the cabinet body 1 and prevent external humid air from entering the cabinet body 1 through the gap between the cover shell 2 and the cabinet body 1.

[0019] The dehumidifier 3 is used to draw the air in the cabinet 1 into the dehumidifier 3, and after the moisture in the air drawn into the dehumidifier 3 is condensed into water droplets, the dehumidified air is discharged back into the cabinet 1, and the water droplets are discharged to the outside of the cover 2 through the water outlet port 6 on the dehumidifier 3 and the drain pipe 7 connected to the water outlet port 6.

[0020] When the air in the cabinet 1 is drawn into the dehumidifier 3 for dehumidification, the motor 13 is first controlled to rotate, and the motor 13 drives the screw 11 to rotate. The air intake hood 14 is threadedly connected to the screw 11, and the air intake hood 14 is slidably connected to the guide rod 12, so that the air intake hood 14 can make a linear motion along the screw 11. By making the air intake hood 14 move linearly along the screw 11, the position of the air intake hood 14 can be changed, which is convenient for efficient extraction of air at different heights, so as to speed up the dehumidification efficiency of the overall air in the cabinet 1, and by controlling the forward and reverse rotation of the motor 13, the air intake hood 14 can be controlled to make a linear reciprocating motion along the screw 11.

[0021] The air dehumidified by the dehumidifier 3 is discharged into the cabinet 1 through the exhaust port 5. Since it is directly discharged into the cabinet 1, the air flow in the cabinet 1 will become complicated, which is not conducive to the air intake hood 14 to extract air at different heights. Therefore, the air discharged through the exhaust port 5 moves toward the cover 2 after passing through the wind shield 9, thereby reducing the impact on the air in the cabinet 1 and facilitating the air intake hood 14 to extract air at different heights in an orderly manner.

[0022] The humidity sensor 16 is used to detect the humidity of the air in the cabinet 1. When the humidity of the air in the cabinet 1 reaches a predetermined value, the control module controls the dehumidifier 3 and the motor 13 to start, so as to timely reduce the humidity of the air in the cabinet 1 to reduce the condensation phenomenon in the power cabinet. When the air humidity in the cabinet 1 is lower than the predetermined value, the dehumidifier 3 and the motor 13 stop working to achieve the purpose of saving energy.

[0023] Furthermore, the drain pipe 7 is arranged at an angle, so as to discharge the water produced in the dehumidifier 3 to the outside of the housing 2 in a timely manner, thereby preventing water from accumulating in the drain pipe 7 and causing a large number of microorganisms to multiply.

[0024] Furthermore, an electric heating tube 17 is provided on the outer surface of the drain pipe 7 located outside the cover shell 2. In cold weather, the drain pipe 7 can be heated by the electric heating tube 17 to prevent the water in the drain pipe 7 from freezing and causing blockage of the drain pipe 7, thereby affecting the normal drainage of the dehumidifier 3.

[0025] Furthermore, a one-way valve 18 is provided at the lower end of the drain pipe 7, and water can only be discharged to the outside of the cover 2 through the one-way valve 18, so as to prevent sewage from entering the dehumidifier 3 through the drain pipe 7 due to water accumulation outside the cabinet 1 in extreme weather conditions. The one-way valve 18 can be a Tesla valve.

[0026] Furthermore, a sealing ring 19 is provided between the drain pipe 7 and the cover shell 2 , and the sealing ring 19 is used to increase the sealing between the drain pipe 7 and the cover shell 2 to reduce the exchange of external air with the air in the cabinet 1 through the connection between the drain pipe 7 and the cover shell 2 .

[0027] The device can control the movement of the air intake hood 14 so that the position of the air intake is constantly changed, which is beneficial to speeding up the overall dehumidification efficiency of the air in the cabinet 1, and can effectively avoid condensation on the electrical components or structural parts in the cabinet 1, and reduce malfunctions caused by condensation. In addition, the device is located as a whole in the cover 2, and will not have a major impact on the use space in the cabinet 1, and the use effect is good.

[0028] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
