First, the protective plate in the above-mentioned device is fixed with bolts. However, for the power cabinet after the transfer is completed and it is put into use, the external protective plate will only occupy space in most cases. Therefore, the protective plate needs to be disassembled, at least on the side against the wall. However, the threaded fixing makes disassembly inconvenient. In addition, the protective plate is a whole design, which makes its storage and refrigeration too inconvenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective device for power equipment, including a power cabinet, wherein shelves are fixedly installed inside the power cabinet;

[0008] The power cabinet is equipped with protective components on three outer sides, and several guiding components are provided on the inner side of the power cabinet.

[0009] The protective assembly includes a first protective plate, a second protective plate hinged to the bottom of the first protective plate, a mounting strip hinged to the bottom of the second protective plate, and a mounting strip hinged to the top of the first protective plate.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 The present invention provides a technical solution: a protective device for power equipment, including a power cabinet 1, wherein a shelf 101 is fixedly installed inside the power cabinet 1;

[0028] The power cabinet 1 is equipped with protective components 2 on its three outer sides, and several guide components 3 are installed on the inner side of the power cabinet 1.

[0029] The protective component 2 includes a first protective plate 201, a second protective plate 202 hinged to the bottom of the first protective plate 201, an mounting strip 203 hinged to the bottom of the second protective plate 202, and an mounting strip 203 hinged to the top of the first protective plate 201. The mounting strip 203 has symmetrically arranged open slots 204 on both sides. A first spring 205 is fixedly installed inside the open slot 204. A movable plate 206 is slidably connected inside the open slot 204. An insert plate 207 is fixedly connected to one side of the movable plate 206 and slides through the end of the mounting strip 203. The first protective plate 201 and the second protective plate 202 form a foldable structure through a hinged design, facilitating storage and unfolding. The mounting strip 203, through the insertion design of the insert plate 207 and the insertion hole 209, enables rapid installation and disassembly of the protective component 2, significantly improving operational efficiency.

[0030] The protective component 2 also includes symmetrically arranged inserts 208 on both sides of the mounting strip 203. The insert 208 has a socket 209 in the middle. The power cabinet 1 has an inner cavity 210. The insert 208 slides into the inner cavity 210 and is fixedly connected to a metal plate 211. A magnetic block 212 is fixedly connected to one side of the inner cavity 210. Finger grooves 213 are symmetrically arranged on the outer side of the insert 208. The insert 208 can be stored inside the power cabinet 1 when not in use by sliding into the inner cavity 210, avoiding external protrusions from affecting placement. At the same time, the magnetic attraction between the magnetic block 212 and the metal plate 211 ensures the stable fixation of the insert 208 and prevents it from accidentally sliding out.

[0031] One end of the first spring 205 is fixedly connected to the mounting strip 203, and the other end of the first spring 205 is fixedly connected to one side of the movable plate 206. The insert plate 207 slides through the mounting strip 203 and is inserted into the socket 209. The automatic reset function of the first spring 205 ensures the stable connection between the insert plate 207 and the socket 209.

[0032] The effective magnetic attraction range of the magnetic block 212 to the metal plate 211 is limited to half of the inner cavity 210. This design ensures that the sleeve 208 can be accurately positioned during sliding, preventing the metal plate 211 from being automatically attracted to the magnetic block 212 in areas far away from it. When the magnetic block 212 is in contact with the metal plate 211, the sleeve 208 enters the inner cavity 210.

[0033] The second protective plate 202 is composed of several single plates that are hinged to each other; the modular design of the second protective plate 202 enables it to adapt to power cabinets 1 of different sizes, improving the versatility and applicability of the protective component 2, while also facilitating maintenance and replacement.

[0034] The guide component 3 includes a first clamping block 301, which is fixed to the inner wall of the power cabinet 1. A second clamping block 302 is attached to one side of the first clamping block 301. First protrusions 303 are symmetrically fixed to both sides of the first clamping block 301. Second protrusions 304 are symmetrically fixed to both sides of the second clamping block 302. A movable column 305 is fixed to one side of the first protrusion 303 and slides through the second protrusion 304.

[0035] A limiting block 307 is fixedly connected to the end of the movable column 305 away from the first protrusion 303. A second spring 306 is fixedly connected between the first protrusion 303 and the second protrusion 304. The second spring 306 is sleeved on the outside of the movable column 305. The automatic reset function of the second spring 306 ensures the stable forming of the constraint hole, avoids the wire harness from being randomly hung or knotted, indirectly realizes the neat arrangement of the wire harness, and improves the management efficiency of the wire harness inside the power cabinet 1.

[0036] Several half-holes are provided at the joint of the first clamping block 301 and the second clamping block 302. Two half-holes can be combined to form a constraint hole. The design of the constraint hole not only facilitates the passage of wire harnesses, but also effectively restricts the wire harnesses, preventing them from moving or getting tangled, thus further improving the safety and aesthetics of the power cabinet 1.

[0037] Working principle: Before using this type of protective device for electrical equipment, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, before moving the power cabinet 1, first insert your finger into the finger groove 213, hold the plug sleeve 208, and pull it outward so that the plug sleeve 208 can slide inside the inner cavity 210, thereby allowing the plug sleeve 208 to extend out of the power cabinet 1 and expose the socket 209.

[0038] Then, pull the two movable plates 206 inside the mounting strip 203 so that they slide inside the open slot 204. This causes the first spring 205 to contract, and the insert plate 207 slides into the open slot 204. When the mounting strip 203 is placed between the two inserts 208 that have already extended out of the inner cavity 210, release the movable plates 206 so that the first spring 205 pushes the movable plates 206 to reset, thereby allowing the insert plate 207 to be inserted into the socket 209.

[0039] Simultaneously operate another mounting strip 203 so that the protective plate composed of the first protective plate 201 and the second protective plate 202 can cover the outside of the power cabinet 1, so as to prevent the outer insulating coating of the power cabinet 1 from being damaged or even deformed by bumps during the transportation of the power cabinet 1.

[0040] Furthermore, when the protective component 2 is not in use, the hinged first protective plate 201 and the second protective plate 202 can be folded and stacked for easy storage.

[0041] By pulling the first clamping block 301 outward, the two half holes are separated. At the same time, the movable column 305 is extended. After the hand is released, the first clamping block 301 and the second clamping block 302 are joined together, and the constraint hole is formed. The wire harness passes through the constraint hole, which makes it easier for the wire harness to pass through the constraint hole and reduces the alignment time. After the wire harness is restricted by the constraint hole, it can be indirectly organized to avoid the wire harness from being accidentally caught or even knotted.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
