AI Technical Summary
Existing electrical control cabinets are prone to water ingress into the bottom during heavy rain, and there is a lack of effective solutions.
A structure including a cabinet, a base, rods, a compression spring, an electromagnet, and metal parts was designed. The energization and de-energization of the electromagnet control the raising and lowering of the cabinet. Combined with the supporting effect of the compression spring, a gap is formed to drain rainwater.
In heavy rain, when the electromagnet is de-energized, the cabinet is supported to create a gap, allowing rainwater to flow through and preventing water from entering from the bottom, thus reducing the risk of accidents.

Technical Field
[0001] This utility model belongs to the field of energy storage, specifically relating to an electrical control cabinet. Background Technology
[0002] Electrical control cabinets are often placed outdoors and need to be considered in response to severe weather, especially heavy rain.

[0012] As a further optimization of this utility model, the middle part of the cabinet is provided with a second protrusion corresponding to the first protrusion, and the second protrusion is also provided with a through hole; the rod passes through the through holes of the first and second protrusions at the same time.
[0013] As a further optimization of this utility model, the end of the rod is provided with a baffle to prevent the rod from detaching from the second outward protrusion.

[0017] As a further optimization of this utility model, the metal part is replaced with a magnet.
[0018] The present invention provides an electrical control cabinet in which the electromagnet is de-energized and the cabinet body is supported by a compression spring, leaving a gap between the cabinet body and the base. Rainwater can then flow through the gap without washing the bottom of the cabinet body. Moreover, the electromagnet is de-energized at this time, making accidents less likely.

[0020] Figure 2 This is a schematic diagram of the electromagnet in the energized state of Example 1;
[0021] The components include: cabinet 1, cabinet cavity 1a, first outward protrusion 1b, second outward protrusion 1c, base 2, base cavity 2a, rod 3, compression spring 4, electromagnet 5, metal part 6, power supply 7, and baffle 8. Detailed Implementation
[0022] Example 1
[0023] This embodiment includes a cabinet 1, a base 2, a rod 3, a compression spring 4, an electromagnet 5, and a metal part 6.
[0024] Cabinet 1 has a cabinet cavity 1a at the bottom, which is independent of the upper cavity. Electromagnet 5 is located in cabinet cavity 1a. The control module and power supply 7 of electromagnet 5 can be located in the upper cavity, with only the iron core and coil located in cabinet cavity 1a.
[0025] In this embodiment, several electromagnets 5 are installed inside the cabinet cavity 1a, and the electromagnets 5 are evenly distributed in an array. One end of each electromagnet 5 faces the bottom plate of the cabinet 1. In this embodiment, the bottom plate of the cabinet 1 is made of a mesh and is made of a non-metallic material. In other embodiments, the bottom plate can also be made of a thin metal plate. Using a thin metal plate can enhance the sealing effect at the bottom, preventing rainwater from entering.
[0026] The cabinet body 1 has a first protrusion 1b on the lower outer side, and the first protrusion 1b has a through hole. In this embodiment, the first protrusion 1b is provided below each of the four right-angled sides of the cabinet body 1. At the same time, a second protrusion 1c is provided in the middle of the four right-angled sides corresponding to the first protrusion 1b. The first protrusion 1b and the corresponding second protrusion 1c are both provided with through holes with collinear axes.
[0027] The base 2 is used to support the cabinet 1. The base 2 has a base cavity 2a and is pre-embedded in the ground. Metal parts 6 are fixed in the base cavity 2a. The number of metal parts 6 is the same as the number of electromagnets 5, and the positions of the metal parts 6 and electromagnets 5 correspond one-to-one.
[0028] There are four rods 3, which correspond to the four right-angled sides of the cabinet 1. Each rod 3 passes through the first outward protrusion 1b and the second outward protrusion 1c of the corresponding right-angled side. The bottom end of the rod 3 is fixed to the base 2, and the upper end of the rod 3 is also provided with a baffle 8. The baffle 8 is detachably connected to the rod 3 and is used to prevent the rod 3 from detaching from the second outward protrusion 1c.
[0029] The compression spring 4 is sleeved on the rod 3 and located between the first protrusion 1b and the base 2.
[0030] Under normal circumstances, when the electromagnet 5 is energized, it attracts the metal part 6 of the base 2, and the compression spring 4 is pressed down. At this time, the bottom plate of the cabinet 1 is attached to the base 2.
[0031] In heavy rain, the electromagnet 5 is de-energized, and the cabinet 1 is supported by the compression spring 4, creating a gap between the cabinet 1 and the base 2. Rainwater can then flow through this gap without washing away the bottom of the cabinet 1. Furthermore, since the electromagnet 5 is de-energized at this time, even if rainwater splashes into the cabinet cavity 1a, it is unlikely to cause an accident.
[0032] Example 2
[0033] The difference between this embodiment and embodiment 1 is that the metal part 6 is replaced with a magnet. In this embodiment, by changing the north and south poles of the electromagnet 5, the attraction and repulsion effects are achieved, which further enhances the stability of the cabinet 1 when it is attracted to the base 2, as well as the distance when it is repelled.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
