Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-8 The present invention provides the following technical solution.

[0033] Example 1: To address the problem that existing technologies typically involve direct placement at the intended use location or installation using bolts, which is particularly inconvenient for outdoor installations, this example provides the following technical solution: a high-voltage switchgear comprising a switchgear body 1, a base 2, fixing blocks 3, fixing plates 4, connecting plates 5, connecting rods 6, and mounting caps 7. When installing the switchgear body 1 outdoors, it is placed on top of the base 2, and fixing blocks 3 are fixedly connected to both the left and right sides of the lower end of the switchgear body 1. The fixing plates 4 are also fixed to the base 2. The fixing blocks 3 are interlocked, and the fixing plate 4, in conjunction with the fixing blocks 3, is used to position the switch cabinet body 1 and the base 2. The fixing plate 4 drives the fixing blocks 3 to form a disassembly structure at the upper end of the base 2. The front and rear sides of the fixing plate 4 are inserted into the middle of the connecting plate 5, and the connecting plate 5 is fixedly connected to the front and rear sides of the base 2 respectively. The front and rear ends of the fixing plate 4 are fixedly connected with connecting rods 6, which are interlocked in the middle of the connecting plate 5. The outer surface of the connecting rod 6 is threaded with a mounting cap 7 for limiting the position, which is interlocked in the middle of the connecting plate 5. Figure 1 , Figure 2 and Figure 3 As shown, the fixing plate 4 is placed on the upper end of the fixing block 3, and the fixing plate 4 and the fixing block 3 are engaged and connected. At the same time, the fixing plate 4 presses and limits the fixing block 3. Both the front and rear ends of the fixing plate 4 are inserted into the connecting plate 5. The fixing plate 4 drives the connecting rod 6 to engage in the middle of the connecting plate 5. Then, the mounting cap 7, which is threaded to the outer surface of the connecting rod 6, is rotated so that the mounting cap 7 engages in the middle of the connecting plate 5. This facilitates the limiting of the fixing plate 4 and the connecting plate 5, so that the switch cabinet body 1 can be stably installed on the upper end of the base 2 very quickly and conveniently.

[0034] Example 2: To address the problem of poor dustproof performance in existing technologies, this example provides the following technical solution: a high-voltage switchgear is equipped with heat dissipation holes 8 and a dustproof mesh 9, as follows... Figure 1 and Figure 4As shown, heat dissipation holes 8 are provided at both the left and right ends of the switch cabinet body 1. At the same time, dustproof nets 9 are attached to the left and right sides of the switch cabinet body 1. While the heat dissipation holes 8 ventilate and dissipate heat inside the switch cabinet body 1, the dustproof nets 9 effectively prevent dust from entering the switch cabinet body 1 through the heat dissipation holes 8, resulting in good dust prevention. Moreover, the dustproof nets 9 can be disassembled by loosening the bolts between the switch cabinet body 1 and the dustproof nets 9, making it easy to clean the dust attached to the dustproof nets 9 and prevent the dustproof nets 9 from being blocked by dust during long-term use.

[0035] Example 3: To address the problem in existing technologies where the wiring harness inside the cabinet lacks a harness assembly for restraint, resulting in a messy wiring harness within the cabinet, this example provides the following technical solution: a high-voltage switchgear, comprising a harness mechanism 10, a movable plate 14, a connecting block 15, a spring 16, a protrusion 17, and an auxiliary plate 18. The harness mechanism 10 is located on the inner wall of the rear end of the switchgear body 1, and includes a harness plate 11 bolted to the inner wall of the rear end of the switchgear body 1, a pressure plate 12 hinged to the left end of the harness plate 11, and a connecting block 18. A cable tray 13 is provided on the cable tray 11 and the pressure plate 12. The pressure plate 12 forms a flip structure on the front side of the cable tray 11, and a movable plate 14 is telescopically connected to the right side of the pressure plate 12. The movable plate 14 and the connecting block 15 form a left-right sliding structure, and the connecting block 15 is fixedly connected to the front side of the right end of the pressure plate 12. A spring 16 is provided between the movable plate 14 and the pressure plate 12, and a positioning protrusion 17 is fixedly connected to the right end of the movable plate 14. The protrusion 17 is inserted into the middle of the auxiliary plate 18, and the auxiliary plate 18 is fixedly connected to the front side of the right end of the cable tray 11. Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the wiring harness inside the switch cabinet body 1 is placed in the wiring groove 13 in the middle of the wiring harness plate 11. Then, the movable plate 14 is pulled, and the movable plate 14 slides between itself and the connecting block 15. The movable plate 14 compresses the spring 16, causing the spring 16 to undergo elastic deformation. Then, the pressure plate 12 is flipped, and the pressure plate 12 rotates with the wiring harness plate 11, thus separating the pressure plate 12 from the wiring harness plate 11. Figure 7 The state shown transforms into the state shown in the figure. Figure 6In the state shown, the movable plate 14 drives the protrusion 17 to align with the center of the auxiliary plate 18, and then the movable plate 14 is released directly. At this time, the spring 16 restores its elastic deformation, pushing the movable plate 14 to slide between the connecting block 15, so that the movable plate 14 drives the protrusion 17 to insert into the center of the auxiliary plate 18, which facilitates the limiting of the pressure plate 12 and the wire harness plate 11. The setting of the pressure plate 12 and the wire harness plate 11 facilitates the clamping and limiting of the wire harness inside the switch cabinet body 1, making the arrangement of the wire harness in the switch cabinet body 1 more regular and facilitating the later retrieval of the wire harness.
