Short circuits and power outages caused by machinery being too close to high-voltage electrical equipment are common occurrences, sometimes resulting in large-scale power outages. After a power outage, cranes and other maintenance platforms are used to repair the circuits using specialized equipment. However, during crane operations, various factors increase the risk of electric shock. Therefore, it is necessary to use anti-electric shock warning devices for working near live conductors.

[0003] Currently, existing technology CN115072570A discloses a combined early warning device for preventing electric shock during work near live conductors. This device includes a base with a suction cup connected to it. A base plate is hinged to the base via a support rod. An electric field detection module is mounted on the base plate. A laser radar is rotatably connected to the base plate. A first bracket and a second bracket are connected to the base plate. A sleeve is connected to the first bracket, and a rotating rod is inserted into the sleeve. The rotating rod is fixedly connected to the laser radar. A support plate is connected to the rotating rod. A camera is positioned above the support plate. A conversion mechanism connects the camera and the laser radar. A first adjustment mechanism connects the support plate and the camera. A second adjustment mechanism connects the laser radar and the base. This invention combines these three detection methods, improving the safety of the device.

[0004] However, the aforementioned anti-electric shock warning device for working near live parts uses a suction cup to attach the detection device to the top of the crane. During crane operation, the warning device is prone to shaking, which can cause the suction cup to loosen and reduce the stability of the warning device connection. Utility Model Content

Detailed Implementation

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0018] Please see Figures 1 to 3 This utility model provides a device for preventing electric shock during work near live conductors, including a detection module 1, a slide rail 2, and an installation assembly 3. The detection module 1 is disposed on one side of the slide rail 2. The installation assembly 3 includes an installation plate 4, a rotating frame 5, a connecting plate 6, a positioning bolt 7, a fixing bolt 8, and an anti-detachment component 9. The rotating frame 5 is fixedly connected to the slide rail 2 and is located at the bottom of the slide rail 2. The connecting plate 6 is assembled on the side of the rotating frame 5 away from the slide rail 2. The installation plate 4 is assembled on one side of the connecting plate 6. The positioning bolt 7 is fixedly connected to the installation plate 4 and is located on the side of the installation plate 4 close to the connecting plate 6. The fixing bolt 8 is threadedly connected to the installation plate 4 and passes through the connecting plate 6. The anti-detachment component 9 is disposed at the end of the fixing bolt 8 away from the connecting plate 6.

[0019] In this embodiment, the mounting assembly 3 is used to mount the detection module 1 and the slide rail 2 on the top of the crane. The detection module 1 can slide within the slide rail 2 and monitor in real time parameters such as the distance and electric field strength between the high-altitude work equipment or personnel and the live conductor (for the principle, please refer to patent CN115072570A, a joint early warning device for preventing electric shock when working near a live conductor). The mounting plate 4 is pre-welded and fixed to the top of the crane. The connecting plate 6 is snapped into the mounting plate 4 and fixed to the mounting plate 4 by the fixing bolt 8. The positioning bolt 7 is used for the connection plate 6 and the mounting plate 4 to be fixed together. When plate 4 is snapped in, it is positioned so that the screw holes of the mounting plate 4 and the connecting plate 6 are aligned. The anti-detachment component 9 is used to fasten the fixing bolt 8, preventing the connecting plate 6 from shaking during crane operation, which would cause the fixing bolt 8 to loosen and thus affect the stability of the installation of the detection module 1. The rotating frame 5 can drive the detection module 1 and the slide rail 2 to rotate on the connecting plate 6, expanding the detection range of the detection module 1 and improving the detection accuracy of the detection module 1. This solves the problem that existing anti-electric shock early warning devices for working near live parts are easily affected by shaking, reducing the stability of the connection of the early warning device.

[0020] Furthermore, the anti-detachment component 9 includes a washer 10 and a fixing pin 11. The washer 10 is sleeved on the end of the fixing bolt 8 away from the connecting plate 6, and the fixing pin 11 is assembled on one side of the fixing bolt 8.

[0021] In this embodiment, the washer 10 and the fixing pin 11 are provided to fasten the fixing bolt 8, prevent the fixing bolt 8 from loosening and falling off due to shaking during crane operation, strengthen the connection effect between the connecting plate 6 and the mounting plate 4, and improve the stability of the device connection.

[0022] Furthermore, the mounting plate 4 includes a base plate 12 and a damping plate 13. The damping plate 13 is mounted on one side of the connecting plate 6. The base plate 12 is fixedly connected to the damping plate 13 and is located on the side of the damping plate 13 away from the connecting plate 6.

[0023] In this embodiment, the base plate 12 is welded and fixed to the crane. The swaying of the crane during operation is transmitted to the damping plate 13, which provides buffering and prevents the fixing bolt 8 from loosening and falling off.

[0024] Furthermore, the rotating frame 5 includes a rotating motor 14, a connecting plate 15, and a support frame 16. The rotating motor 14 is fixedly connected to the connecting plate 6 and is located on one side of the connecting plate 6. The connecting plate 15 is fixedly connected to the output end of the rotating motor 14 and is located on the side of the rotating motor 14 away from the connecting plate 6. The support frame 16 is fixedly connected to the connecting plate 15 and fixedly connected to the slide rail 2, and is located between the slide rail 2 and the connecting plate 15.

[0025] In this embodiment, the controller controls the operation of the rotating motor 14, and the output end of the rotating motor 14 rotates, thereby driving the connecting plate 6 to rotate, which in turn drives the slide 2 and the detection module 1 inside the slide 2 to rotate together, thereby expanding the detection range of the detection module 1. The support frame 16 is provided to support the slide 2.

[0026] Furthermore, the slide 2 includes a slide rail 17, a telescopic cylinder 18, and a buffer rod 19. The slide rail 17 is fixedly connected to the support frame 16 and is located on the side of the support frame 16 away from the connecting plate 15. The telescopic cylinder 18 is fixedly connected to the slide rail 17 and to the detection module 1, and is located between the detection module 1 and the slide rail 17. The buffer rod 19 is fixedly connected to the slide rail 17 and to the detection module 1, and is located on both sides of the telescopic cylinder 18.

[0027] In this embodiment, the slide rail 17 is mounted on the support frame 16, providing an installation location for the detection module 1. The telescopic cylinder 18 extends and retracts, pushing or pulling back the detection module 1, allowing the detection module 1 to slide within the slide rail 17. The buffer rod 19 (existing technology, such as a damping rod) is provided to buffer the force exerted by the telescopic cylinder 18 on the detection module 1, preventing the detection module 1 from sliding too quickly and thus affecting the detection accuracy of the detection module 1.

[0028] The above-disclosed embodiments are merely preferred embodiments of an electric shock warning device for working near live conductors, and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
