[0002] Switchgear, which includes power switchgear, lighting switchgear, and metering cabinets, is the final stage of the power distribution system. Switchgear is a general term for motor control centers. Switchgear is used in applications with dispersed loads and a small number of circuits, while motor control centers are used in applications with concentrated loads and a large number of circuits. They distribute power from a circuit in the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the loads.

[0003] During the use of high-voltage switchgear, when the high-voltage switchgear door is opened quickly, the high-voltage electricity originally static inside the switchgear can easily react with the air, which in turn causes the staff who open the door to be broken down by the voltage, posing a safety hazard.

[0025] Next, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, cross-sectional views of device structures may be partially enlarged and not to scale when describing the embodiments of the present invention. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides a safe high-voltage switch cabinet housing with a built-in disinfection system. The disinfection component installed inside the utility model can achieve the effect of disinfection before injection, saving time and labor.

[0028] Figure 1-5 The following is a schematic diagram of a structure of a safety high-voltage switch cabinet housing embodiment of the utility model, please refer to Figure 1-Figure 5 In this embodiment, a safety high-voltage switchgear housing includes a cabinet body 100 , a fixing frame 200 , a locking assembly 300 , a limiting assembly 400 and a protective plate 500 .

[0029] A fixing plate 110 is installed on the symmetrical side walls of the cabinet 100, a guide groove 120 is opened on the side walls of the fixing plate 110, a rack 130 is installed inside the guide groove 120, a card slot 140 is opened on the top of the cabinet 100, and a second guide groove 150 is opened on the symmetrical side walls of the cabinet 100.

[0030] The fixing frame 200 is located on the side wall of the cabinet 100, and the fixing frame 200 is slidably connected between the two fixing plates 110. The inner wall of the fixing frame 200 is hinged with a door panel 210, and a handle 220 is installed on the side wall of the door panel 210. The side wall of the fixing frame 200 is provided with a receiving groove 230, and the side wall of the door panel 210 is provided with a limiting hole 240. The locking assembly 300 includes a gear 310 rotatably connected to the inside of the door panel 210 and a limiting rod 320 slidingly located inside the receiving groove 230. The gear 310 is meshed with the rack 130, and a threaded rod 330 is installed on the side wall of the gear 310. The side wall of the limiting rod 320 is provided with a threaded hole 340. The threaded rod 330 rotates and extends into the inside of the threaded hole 340. During normal use, the door panel 210 and the fixing frame 200 close the opening of the cabinet 100 to prevent current from escaping from the opening of the cabinet 100. When the door panel 210 needs to be opened, At 10, first pull the handle 220 to drive the door panel 210 to move outward. Since the limit rod 320 is located inside the limit hole 240 at this time, when the door panel 210 is pulled, the fixed frame 200 is driven to move away from the cabinet 100, and the fixed frame 200 drives the gear 310 to move, and the rack 130 drives the gear 310 and the threaded rod 330 to rotate. The threaded rod 330 uses the screw rod structure to push the limit rod 320 to move into the accommodating groove 230, and the limit rod 320 is separated from the limit hole 240. At this time, pull the handle 220 to drive the door panel 210 to flip open. In the process of the fixed frame 200 moving and separating from the cabinet 100, the current inside the cabinet 100 dissipates from the surrounding areas of the fixed frame 200, which can prevent the current inside the cabinet 100 from spreading rapidly through the air when the door panel 210 is directly opened, causing a safety hazard to the staff.

[0031] The limiting assembly 400 includes a side panel 410 installed on the side wall of the fixed frame 200 and a block 420 slidingly located on the side wall of the fixed frame 200. A motor 430 is installed on the side wall of the side panel 410. A second threaded rod 440 is installed on the output end of the motor 430. A second threaded hole 450 is opened on the side wall of the block 420. The second threaded rod 440 rotates and extends into the second threaded hole 450. In a normal state, the block 420 is located inside the slot 140. The motor 430 is connected to an external mobile device. When the door panel 210 needs to be opened, the external mobile device is used to start the motor 430 to drive the second threaded rod 440 to rotate. When the second threaded rod 440 rotates, the screw structure is used to push the block 420 to move toward the side panel 410. The block 420 is separated from the inside of the slot 140. At this time, the door panel 210 is pulled to drive the fixed frame 200 to separate from the cabinet 100.

[0032] The protective plate 500 is located at the top of the cabinet 100, and a spring 510 is installed at the bottom of the protective plate 500. The bottom end of the spring 510 is connected to the top of the cabinet 100. The symmetrical side walls of the protective plate 500 are installed with guide plates 520, and the side walls of the guide plate 520 are installed with guide blocks 530. The guide blocks 530 are located inside the second guide groove 150. When the top of the protective plate 500 is impacted, the impact force pushes the protective plate 500 downward and squeezes the spring 510. The spring 510 buffers the impact force. The protective plate 500 protects the cabinet 100 to prevent the impact force from directly acting on the cabinet 100 and causing safety hazards. During the movement of the protective plate 500, the guide block 530 slides inside the second guide groove 150 to guide the protective plate 500.

[0033] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
