Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to an adjustable moisture-proof and dust-proof power distribution cabinet. Background Art

[0002] The main function of the adjustable moisture-proof and dust-proof distribution cabinet is to protect the internal electrical components from moisture and dust while providing power distribution. In industrial plants, ships, field work sites, mines, subway tunnels and other places, moisture and dust may cause serious damage to electrical equipment and even cause electrical failures, fires and other safety problems, so protective measures are needed.

[0003] This type of distribution cabinet usually adopts a sealed structure and is equipped with an adjustment function. It can be automatically or manually adjusted according to the humidity and dust conditions of the environment to keep the interior dry and clean, ensuring the normal operation and long-term reliability of the equipment.

[0004] However, the moisture-proof structure is usually installed inside the cabinet, and the air entering the distribution cabinet needs to be dehumidified after operation. The dryness of the gas entering the distribution cabinet cannot be controlled from the source, so the dehumidification efficiency is low. Since the dust-proof structure is usually fixed, when the distribution cabinet does not need to ensure complete airtightness, for example, when heat dissipation is required, the dust-proof function cannot be controlled to be turned on or off at any time according to usage requirements, so it has certain limitations when used. Utility Model Content

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Please see attached Figure 1 To Attachment Figure 5 As shown, an adjustable moisture-proof and dust-proof distribution cabinet includes a box body 1, a front door 2 is hinged at the right end of the front side of the box body 1, a handle 16 is installed on the left part of the front side of the front door 2, and locking knobs 17 are installed on the upper and lower sides of the handle 16. The rear end of the locking knob 17 passes through the front door 2 and is bent and fixed with the left end of the front side of the box body 1. The locking knob 17 is rotatably connected to the front door 2. A dehumidification box 3 is provided on the left side of the box body 1, and a plurality of air inlet holes 10 are reserved at the lower part of the dehumidification box 3. A fan 4 is installed on the upper inner top surface, and upper and lower layers are provided between the inner walls of the dehumidification box 3. A dehumidification plate 13 is provided with an installation groove in the middle of the dehumidification plate 13, in which a moisture-absorbing bag 14 is detachably installed. A vent is provided on the top surface of the dehumidification box 3 and is connected to the fan 4. The bottom end of the air supply pipe 5 passes through the dehumidification box 3 and is connected to the output port of the fan 4. The top end is bent and passes through the left side wall of the box body 1 and is connected to the air dispersion plate 6 fixed on the left inner wall of the box body 1. A plurality of evenly distributed vents 11 are reserved on the right side of the air dispersion plate 6. The air dispersion plate 6 is fixed with three front and rear air dispersion plates 6 on the left inner wall of the box body 1, and the front and rear air dispersion plates 6 are connected through a connecting pipe 15.

[0028] A number of equipment mounting frames 7 distributed up and down are fixedly mounted on the inner wall at the rear side of the box body 1. A number of heat dissipation holes 12 are opened in the middle of the right side wall of the box body 1. A baffle frame 8 surrounding the heat dissipation holes 12 is fixed on the right side surface. The top of the baffle frame 8 is an open structure and a card slot is reserved. A baffle 9 is slidably engaged with the card slot. The left side of the baffle 9 is slidably connected to the box body 1, and the bottom end contacts the inner wall of the bottom end of the baffle frame 8.

[0029] Through the above structure, the dehumidification box 3 can dehumidify the air outside the distribution cabinet and then transport it into the box body 1. By adjusting the height of the baffle 9 in the baffle frame 8, the humid and hot air in the box body 1 can be transported to the outside of the box body 1 through the heat dissipation holes 12 to realize the dehumidification function. The baffle 9 can achieve a good dust-proof effect.

[0030] During the specific implementation of the utility model: when it is necessary to dehumidify and prevent moisture in the distribution cabinet, the fan 4 is driven to work, and the fan 4 sucks the air outside the dehumidification box 3 into the dehumidification box 3 through the air inlet 10, and then passes through the moisture absorption bags 14 on the dehumidification plates 13 of several layers, and is transported to the air dispersion plate 6 through the air pipe 5, and then enters the box body 1 through the vent 11. At the same time, the baffle 9 is pulled upward to expose the heat dissipation hole 12, so that the dry air entering the box body 1 can be replaced by the original hot and humid air convection, and the hot and humid gas is discharged from the box body 1 through the heat dissipation hole 12, so as to realize the moisture-proof and dehumidification function. When the distribution cabinet completes dehumidification, the baffle 9 is located at the bottom of the baffle frame 8, the heat dissipation hole 12 is blocked, and the box body 1 is isolated from the outside world, so as to achieve a good dustproof effect.

[0031] In particular, when the moisture absorption bag 14 is saturated with absorbed moisture, it needs to be disassembled and replaced. In addition, multiple air dispersion plates 6 are arranged in front and behind, and are connected through the connecting pipe 15 to further improve the dehumidification effect.

[0032] It is worth mentioning that the fan 4 in the present invention is an existing device well known to those skilled in the art, and its circuit connection method and its use control method are both existing technologies.

[0033] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention of the utility model, they can creatively design a structure and embodiment similar to the technical solution, which should belong to the protection scope of the utility model.
