However, due to the complex environment of power plant sites, frequent personnel movement, and the concentrated installation locations of some equipment, accidental contact with switches or control panels is highly likely during daily operation, maintenance, and personnel movement. Such accidental contact can lead to abnormal equipment start-up and shutdown, affecting the stable operation of the power system and even causing serious safety accidents and significant economic losses. Current technologies offer relatively limited measures to prevent accidental contact with electrical equipment. Some protective devices are complex in structure, expensive, and lack sufficient protective effectiveness, failing to fundamentally and effectively prevent accidental contact.

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.
[0020] like Figures 1 to 4 As shown, this utility model provides an electrical anti-accidental contact device for power plants, including a mounting base 1 for installation at electrical equipment switches or control panels. Mounting holes 2 are provided at each of the four corners of the mounting base 1. Fixing bolts 3 are threaded into the mounting holes 2. A protective frame 4 is fixedly connected to the surface of the mounting base 1. A protective cover 5 is hinged to the outer side of the protective frame 4 via a hinge. One end of the protective cover 5 is symmetrically fixedly connected to a hinge member 6. Rotating bars 7 are rotatably connected inside the hinge members 6, and the maximum rotation angle of the rotating bars 7 is 180 degrees. Handles 8 are fixedly connected to the other ends of the two rotating bars 7. The surface of handle 8 is covered with an anti-slip pad, which can improve the tactile feel of handle 8 and increase the friction between handle 8 and the operator's hand. The surface of the protective frame 4 is symmetrically fixedly connected with a fixing block 9. The outer side of the fixing block 9 is provided with a snap-fit groove 10, and the snap-fit groove 10 is snapped with the rotating bar 7. The two sides of the fixing block 9 are symmetrically provided with fastening holes 11. The inside of the rotating bar 7 is provided with a fastening groove 12. The inside of the fastening groove 12 is provided with a fastening spring 13. The two ends of the fastening spring 13 are symmetrically fixedly connected with fastening posts 14, and the other end of the fastening post 14 passes through the fastening groove 12 and is snapped with the fastening hole 11.
[0021] refer to Figure 2 and Figure 3 The inner walls of both the protective frame 4 and the protective cover 5 are fixedly connected with an anti-electromagnetic membrane 15, and the surface of the protective cover 5 is provided with an anti-electromagnetic transparent glass 16.
[0022] As a technical optimization of this utility model, by setting up the anti-electromagnetic film 15 and the anti-electromagnetic transparent glass 16, the needs of operators to clearly observe the status of the internal switches or control panels without opening the protective cover 5 are met, the interference of external electromagnetic fields on the equipment is effectively shielded, and the electromagnetic radiation generated by the equipment itself is suppressed from spreading outward.
[0023] refer to Figure 2 and Figure 3 The inner wall of the protective frame 4 is fixedly connected to the bearing frame 17, and the inner wall of the protective cover 5 is fixedly connected to the conductive sealing gasket 18, and the conductive sealing gasket 18 is used in conjunction with the bearing frame 17.
[0024] As a technical optimization of this utility model, by setting the support frame 17 and the conductive sealing gasket 18, dust and moisture can be prevented from entering the interior of the protective frame 4 through the gap between the protective frame 4 and the protective cover 5, thus preventing damage to electrical components due to dust accumulation or moisture erosion and extending the service life of the equipment.
[0025] refer to Figure 3 A sealing frame groove is provided on the rear side of the mounting base 1, and a conductive sealing frame 19 is fixedly connected inside the sealing frame groove.
[0026] As a technical optimization of this utility model, the setting of the conductive sealing frame 19 can improve the sealing performance of the mounting base 1 after installation, thereby improving the sealing effect of the device after installation.
[0027] refer to Figure 4 A limiting groove 20 is provided on the inner wall of the fastening groove 12, and a limiting ring 21 is fixedly connected to the surface of the fastening column 14, and the limiting ring 21 is slidably connected to the limiting groove 20.
[0028] As a technical optimization of this utility model, by setting the limiting groove 20 and the limiting ring 21, the maximum movement trajectory of the fastening column 14 can be limited, and the phenomenon of it sliding out of the fastening groove 12 and being lost can be prevented.
[0029] refer to Figure 1 A luminous strip 22 is fixedly connected to the upper part of the surface of the protective cover 5, and a label frame 23 is fixedly connected to the lower part of the surface of the protective cover 5.
[0030] As a technical optimization of this utility model, the luminous strip 22 makes it easier for people to identify the location of the device in low-light environments, and the label frame 23 can be used to attach relevant equipment information, which facilitates the management and maintenance of the equipment.
[0031] The working principle and usage process of this utility model are as follows: When using this electrical anti-accidental contact device to protect the switches or control panels of electrical equipment in a power plant, firstly, the anti-accidental contact device is installed at the switch or control panel of the electrical equipment through the mounting holes 2 at the four corners of the mounting base 1 and the fixing bolts 3, achieving a stable installation of the device. Then, when the protective cover 5 is closed, the conductive sealing gasket 18 on the inner wall of the protective cover 5 is tightly fitted with the bearing frame 17 on the inner wall of the protective frame 4. At the same time, the conductive sealing frame 19 on the rear side of the mounting base 1 also plays a sealing role, forming a relatively sealed space to prevent dust, moisture, etc. from entering. Meanwhile, the anti-electromagnetic film 15 and the anti-electromagnetic transparent glass 16, with their special materials and structures, can absorb and reflect external electromagnetic signals, preventing electromagnetic interference from entering. Inside the device, to protect electrical equipment from electromagnetic interference, when it is necessary to open the protective cover 5, the operator first presses the fastening post 14 to retract it into the fastening groove 12 of the rotating bar 7 and compresses the fastening spring 13. Then, the operator holds the handle 8 and pulls it outward to disengage the rotating bar 7 from the snap-fit groove 10 of the fixing block 9. Then, the operator rotates the handle 8 to drive the rotating bar 7 and the protective cover 5 to rotate around the hinge, thus opening the protective cover 5. When closing, the operator flips the protective cover 5 to align it and closes it. The operator presses the fastening post 14 again to retract it into the fastening groove 12, and then rotates the handle 8 to make the rotating bar 7 snap into the snap-fit groove 10. At this time, the fastening post 14 snaps into the fastening hole 11 under the action of the fastening spring 13, thus fixing the rotating bar 7 and achieving a secure closure of the protective cover 5.
