[0018] The technical solution of the present invention is further described below through the accompanying drawings and embodiments.

[0020] Embodiment 1 like Figure 1 As shown, the present invention provides a novel low-voltage power distribution cabinet, including a cabinet body 1, a cabinet door 2 is installed on the front of the cabinet body 1, and an observation window 3 is opened above the cabinet door 2 to facilitate observation of the operation of the equipment inside the cabinet body 1. A door handle 4 is installed on one side of the cabinet door 2 to facilitate the operator to operate when the cabinet door 2 needs to be opened.
[0021] like Figure 2 and Figure 3 As shown, condensation boxes 6 are arranged on both sides of the cabinet 1. The bottom of the condensation box 6 is open and a condensation assembly is installed inside. In this embodiment, the condensation assembly includes a refrigeration sheet 61 installed on the cabinet 1. The refrigeration sheet 61 is provided with fins 62. Figure 4 As shown. The refrigeration plate 61 can be powered on to quickly cool down, and the fins 62 can increase the contact area with the air, thereby enhancing the refrigeration effect of the condenser box 6. The air entering the cabinet 1 can be quickly cooled down, thereby reducing the temperature inside the cabinet 1. Moreover, when the air entering the condenser box 6 contains a lot of water vapor, a part of the water vapor can be condensed on the condensation component during the process of passing through the condenser box 6, thereby reducing the water vapor content in the air entering the cabinet 1, thereby reducing the humidity inside the cabinet 1. In addition, the parts and structure of the condensation component can also be changed according to actual conditions, as long as the cooling of the incoming air and the condensation of water vapor can be achieved. A dustproof net 63 is installed at the bottom of the condenser box 6, which can effectively prevent impurities in the air from entering the condenser box 6.
[0022] An air inlet 13 located on the side of the cabinet 1 is provided above the interior of the condensation box 6 , and a suction fan 14 is installed at the air inlet 13 , so that external air can smoothly pass through the condensation box 6 into the interior of the cabinet 1 .
[0023] The interior of the cabinet 1 is divided into an equipment compartment 11 located at the top and a dehumidification compartment 12 located at the bottom by a support plate 10. Figure 5 As shown, a vent 101 is provided on the support plate 10, so that the air in the dehumidification chamber 12 can effectively enter the equipment chamber 11. A partition net 102 is provided at the vent 101 to prevent the device in the equipment chamber 11 from falling into the dehumidification chamber 12.
[0024] The equipment compartment 11 is provided with an equipment installation assembly, which includes a fixing frame 19 vertically installed between the support plate 10 and the top of the cabinet 1, and the fixing frame 19 is provided with mounting holes 20 arranged longitudinally, and a mounting plate 21 is fixed to the fixing frame 19 by mounting bolts. The installation position of the mounting plate 21 can be adjusted at any time as needed, so that it can be suitable for components of various models.
[0025] Partitions 15 are installed on both sides of the equipment installation assembly, and an air inlet channel 16 is formed between the partition 15 and the inside of the cabinet 1. Slots corresponding to the air inlet channel 16 are opened on both sides of the support plate 10, so that the air inlet channel 16 is connected to the dehumidification chamber 12. This structure can ensure that the air entering the cabinet 1 from the condensation box 6 first enters the dehumidification chamber 12 along the air inlet channel 16, and the incoming air is dehumidified for the second time.
[0026] The dehumidification chamber 12 is provided with a support frame 25 connected to the bottom of the support plate 10. A dehumidification material 26 is placed on the support frame 25 to effectively absorb water vapor entering the air. Figure 6 As shown, the middle part of the support frame 25 is provided with air holes 251, which can increase the contact area between the air entering and the dehumidification material 26, which is conducive to enhancing the dehumidification effect, and when the dehumidification material 26 absorbs water vapor, the water vapor can be converted into liquid water and drip from the air holes 251. The bottom of the dehumidification chamber 12 is an inverted cone structure with a central bottom and high surroundings, and a downpipe 9 is opened at the bottom to facilitate the discharge of the liquid water absorbed and converted by the dehumidification material 26 from the inside of the cabinet 1.
[0027] An air outlet 17 is provided at the top of the equipment compartment 11, and an exhaust fan 18 is installed in the air outlet 17 to exhaust the air inside the cabinet 1 and accelerate air circulation. A return air component 7 connected to the top of the cabinet 1 is installed above the air outlet 17, and the return air component 7 is connected to the bottom of the condensation box 6. Figure 7 and Figure 8As shown, the return air assembly 7 includes a main return air duct 71 and a side return air duct 72, the main return air duct 71 is connected to the air outlet 17, and the side return air duct 72 is connected to the bottom of the main return air duct 71 and is respectively connected to the condensation boxes 6 on both sides. This structure can effectively recycle the air that has been dehumidified last time, so that the water vapor content in the air that enters the condensation box 6 again is low, which can not only improve the dehumidification efficiency and ensure that the air inside the cabinet 1 is always in a relatively dry state, but also effectively extend the use time of the dehumidification material 26 and reduce the replacement frequency of the dehumidification material 26.
[0028] A temperature sensor 22, a battery 23 and a controller 24 are provided in the equipment compartment 11. The temperature sensor 22, the condensing assembly, the suction fan 14 and the exhaust fan 18 are all electrically connected to the battery 23 through the controller 24. The operating state of each electrical device can be controlled by the controller 24 according to the actual operating conditions, thereby ensuring the cooling effect inside the cabinet 1.
[0029] The bottom of the cabinet is provided with a foot 5, the inner side of which is provided with a tray 8 movably connected to the bottom of the cabinet 1, and tray handles 81 are provided on both sides of the tray 8 to pull out the tray 8. The bottom of the cabinet 1 is provided with a slot 82, in which the tray 8 is movably connected.
[0030] The length of the receiving tray 8 is not less than the maximum distance between the condensation boxes 6 on both sides, and the width of the receiving tray 8 is not less than the width of the condensation boxes 6. The receiving tray 8 can effectively receive the liquid water dripping from the condensation boxes 6 and the downpipe 9.
[0031] Therefore, the present invention adopts the above-mentioned new type of low-voltage distribution cabinet, which can effectively reduce the temperature inside the cabinet, and at the same time can efficiently remove water vapor in the air, so that the air entering the cabinet is as dry as possible, which is beneficial to improving the service life of various components inside the cabinet.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
