Description

Technical Field

[0001] The utility model relates to the technical field of dehumidification devices, in particular to a dehumidification device for a distribution box. Background Art

[0002] A dehumidifier for a distribution box is a device used to control the humidity in a distribution box. Since distribution boxes are usually located in a confined space, excessive humidity may cause malfunction or even damage to electrical equipment. Dehumidifiers absorb moisture from the air and reduce humidity, thereby keeping the distribution box dry and ensuring the normal operation of electrical equipment. Dehumidifiers usually use principles such as desiccant, condensation or membrane separation to achieve dehumidification. The specific model and working principle may vary depending on the manufacturer and product.

[0003] At present, when the distribution box operates in a high temperature environment, the internal parts and metal surfaces will be heated. When the temperature difference between it and the external environment reaches a certain level, it will cause moisture condensation, resulting in increased humidity. Excessive humidity may cause the wires, sockets and electrical equipment in the distribution box to rust, corrode or get damp, which may cause short circuits, fires or equipment damage. Therefore, it does not meet the existing needs. We have proposed a dehumidification device for distribution boxes. Utility Model Content

[0023] Embodiment 1: This embodiment is intended to solve the problem that when the distribution box is operated in a high temperature environment, the internal parts and metal surfaces will be heated. When the temperature difference between the internal parts and the external environment reaches a certain level, it will cause moisture condensation, resulting in increased humidity. Excessive humidity may cause the wires, sockets and electrical equipment in the distribution box to rust, corrode or get damp, which may cause short circuits, fires or equipment damage. Please refer to Figure 1-6A dehumidification device for a distribution box includes a distribution box body 110, a movable door 120 is installed on the side of the distribution box body 110, a fan housing 130 is arranged at the end of the distribution box body 110, and the fan housing 130 is detachably connected to the surface of the distribution box body 110, a placement tube 111 is arranged inside the distribution box body 110, a placement box 112 is arranged inside the distribution box body 110, and desiccants 170 are arranged inside the placement tube 111 and the placement box 112 respectively.

[0024] There are two placement barrels 111, which are arranged on both sides of the distribution box body 110. The end of the placement barrel 111 body is threadedly connected with a placement cover 114. A groove 140 is provided at the end of the distribution box body 110. There are two grooves 140. A slide groove 141 is provided between the two grooves 140. A threaded groove 142 is also provided on the surface of the distribution box. A limiting ball 143 is provided on the side of the threaded groove 142. The slide groove 141 is connected to the limiting ball 143.

This ensures that the placement barrel 111 is fixed in the distribution box body 110, providing reliable support and protection.

[0025] A pressing cover 144 is provided at the end of the groove 140 and the slide 141. The pressing cover 144 is set as a π-shaped cover. A piston rod 145 is provided at the bottom of the pressing cover 144. A notch 131 is provided at the bottom of the fan housing 130. The notch 131 is slidably connected to the pressing cover 144. A telescopic column 150 is provided at the bottom of the pressing cover 144. The other end of the telescopic column 150 is connected to the bottom of the groove 140. A spring 151 is sleeved on the outer side of the telescopic column 150. A piston disc 152 is connected to the bottom of the piston rod 145. The piston disc 152 is slidably connected to the slide 141.
