[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figure 1 to Figure 7 As shown, a low-voltage fixed switch cabinet in an embodiment of the utility model includes a cabinet 1, in which electrical components are installed, and electrical equipment is controlled by the electrical components. A cabinet door 2 is rotatably connected to the cabinet 1, and the electrical components in the cabinet 1 can be maintained after the cabinet door 2 is opened, and the cabinet door 2 can protect the electrical components in the cabinet 1.

[0030] like Figure 1 to Figure 7As shown, a groove 21 is provided on a side wall of the cabinet door 2 close to the cabinet body 1, and a plurality of U-shaped clips 3 are installed on the side wall of the groove 21. The U-shaped clips 3 can be installed on the side wall of the groove 21 by welding, clamping, bolt connection or other installation methods. A hygroscopic component 5 can be placed in the U-shaped clip 3, and the hygroscopic component 5 can absorb moisture in the cabinet body 1. An exhaust passage 23 is provided at the upper end of the cabinet door 2, and the exhaust passage 23 is opened from a side wall close to the cabinet body 1 to a side wall away from the cabinet body 1. After the hygroscopic component 5 absorbs moisture in the cabinet body 1, when it is used during the day, the electrical components in the cabinet body 1 generate heat, and the heat is transferred to the hygroscopic component 5. The hot air can dry the hygroscopic component 5. The hygroscopic component 5 will generate hot steam during the drying process. Since the hot steam flows upward, the generated hot steam will flow upward in the groove 21 and finally be discharged from the exhaust passage 23. It is possible to reduce the situation where the hot steam is difficult to be discharged from the cabinet body 1 for a long time and affects the electrical components, and reduce the impact of moisture on the low-voltage fixed switch cabinet.

[0031] In the above embodiment, by arranging the moisture absorbing component 5 in the cabinet door 2, the moisture absorbing component 5 dries itself by absorbing the heat generated by the electrical components in the cabinet body 1, and the moisture absorbing performance of the moisture absorbing component 5 is restored while the moisture is precipitated, which can be completed without using additional drying equipment, and is energy-saving and environmentally friendly. By arranging the exhaust channel 23, the hot steam formed by the moisture being heated can be quickly discharged through the exhaust channel 23, and it is not easy to stay in the cabinet body 1 to affect the electrical components in the cabinet body 1, thereby reducing the impact of moisture on the low-voltage fixed switch cabinet.

[0032] In another embodiment, if Figure 1 to Figure 7 As shown, a mesh plate 6 matching the groove 21 is installed on the cabinet door 2, and the mesh plate 6 and the side wall of the groove 21 are interference fit, and the mesh plate 6 can be stuck in the groove 21. The mesh plate 6 is used to further fix the moisture absorbing component 5 to avoid the moisture absorbing component 5 falling off during the opening and closing of the cabinet door 2 as much as possible.

[0033] Specifically, Figure 1 to Figure 7 As shown, a threaded hole 22 is provided on the side wall of the groove 21, a mounting hole 61 matching the threaded hole 22 is provided on the mesh plate 6, a bolt 7 matching the mounting hole 61 is installed on the mesh plate 6, and the bolt 7 passes through the mounting hole 61 and is threadedly connected to the threaded hole 22, that is, the mesh plate 6 is detachably installed on the cabinet door 2. Fixing the cabinet door 2 and the mesh plate 6 by the bolt 7 can improve the stability of the mesh plate 6 and prevent the mesh plate 6 from falling off during multiple opening and closing of the cabinet door 2 as much as possible.

[0034] Preferably, a guide groove can be set on the side wall of the mesh plate 6 close to the moisture absorbing component 5, so that the mesh plate 6 can also play a guiding role, allowing the hot steam to flow along the direction of the guide groove of the mesh plate 6, and finally be discharged through the exhaust channel 23, thereby further reducing the impact of the hot steam on the electrical components in the cabinet 1.

[0035] like Figure 1 to Figure 4 As shown, a handle 62 is fixedly connected to one end of the mesh plate 6 away from the cabinet door 2 , and the handle 62 can be used to facilitate the removal of the mesh plate 6 .

[0036] In the above embodiment, the moisture absorbing component 5 can be further fixed by setting the mesh plate 6, and at the same time, a guide groove is set on the mesh plate 6 to make the hot steam flow toward the exhaust channel 23 and be discharged through the exhaust channel 23, thereby further reducing the impact of the hot steam on the electrical components in the cabinet 1.

[0037] In another embodiment, the U-shaped clip 3 is arranged obliquely, and the bottom end of the U-shaped clip 3 is fixedly connected to the guide tube 4. The guide tube 4 is provided with a connecting hole 41 matching the U-shaped clip 3, and the connecting hole 41 and the U-shaped clip 3 are connected. The hygroscopic component 5 is a calcium chloride hygroscopic layer. After the hygroscopic component 5 absorbs moisture, the calcium chloride in the hygroscopic component 5 combines with moisture and precipitates the moisture into water. The moisture can flow into the guide tube 4 through the U-shaped clip 3. The guide tube 4 is vertically arranged, and the water flows downward along the direction in which the guide tube 4 is arranged to the bottom of the guide tube 4.

[0038] like Figure 1 to Figure 7 As shown, a liquid collecting tank 8 matching with the flow guide pipe 4 is provided on the cabinet door 2, and the liquid collecting tank 8 is provided at the end of the cabinet door 2 away from the cabinet body 1, that is, the liquid collecting tank 8 is provided on the outer surface of the cabinet door 2. A flow guide hole 42 is provided on the flow guide pipe 4, and the flow guide hole 42 passes through the cabinet door 2 and the liquid collecting tank 8, and connects the flow guide pipe 4 and the liquid collecting tank 8. Water enters the liquid collecting tank 8 through the flow guide hole 42, and the water is temporarily stored by the liquid collecting tank 8. A transparent plate 81 is provided on the liquid collecting tank 8, through which the water in the liquid collecting tank 8 can be observed, and the humidity in the cabinet body 1 can be estimated by the water in the liquid collecting tank 8, and whether it needs to be further dried or used directly can be selected according to the amount of water in the liquid collecting tank 8.

[0039] Preferably, a drainage component is provided at the lower end of the liquid collecting tank 8, and the drainage component can drain the water in the liquid collecting tank 8. The drainage component can be a structure that can be used for drainage, such as a through hole, a drainage pipe, a drainage valve, etc.

[0040] like Figure 5As shown, a partition plate 31 is fixedly connected to the middle of the U-shaped clip 3, and the partition plate 31 divides the U-shaped clip 3 into two layers, the upper and lower layers, and the hygroscopic component 5 is installed on the upper layer of the U-shaped clip 3. When the hygroscopic component 5 absorbs moisture and forms water, the water enters the lower layer, and the water flows to the guide pipe 4 in the lower layer, and finally flows to the liquid collecting tank 8. This can avoid the influence of the water flow on the hygroscopic component 5 in other parts, and at the same time facilitate the precipitation of water.

[0041] In the above embodiment, the moisture absorbing component 5 precipitates moisture into water, and by collecting the water, the remaining amount of the water is judged, and the moisture condition in the low-voltage fixed switch cabinet can be judged, so as to make a corresponding use strategy. The moisture condition of the low-voltage fixed switch cabinet can be judged by visual means, so that the judgment can be more accurate.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
