[0020] See also Figure 1-Figure 3 As shown in the figure, the mounting member includes a base plate 1, which is fixedly connected to the bottom end of the alarm 3, and mounting holes 7 are formed through the four corners of the upper end of the base plate 1.

[0021] See also Figure 2 and Figure 3 In the figure, the rotating member includes a turntable 9, which is fixedly connected to the rear end of the rotating shaft 12, and a handle 10 is fixedly connected to the rear end edge of the turntable 9.

[0022] See also Figure 3 and Figure 4 In the figure, a rubber ring 11 is fixedly connected to the middle part of the rear end of the disc-shaped shell 4, and the inner wall of the rubber ring 11 is tightly fitted with the outer wall of the rotating shaft 12; specifically, relying on the friction between the rubber ring 11 and the rotating shaft 12, a damping feeling can be achieved when the warning tape 16 is pulled outward, thereby preventing the rotating shaft 12 from continuing to rotate due to inertia, and the rotating shaft 12 can maintain a certain fixed state after the rotation ends.

[0023] See also Figure 1-Figure 4 In the figure, the limiting member includes a limiting plate 6, which is fixedly connected to the end of the warning tape 16 away from the rotating shaft 12, and a screw hole 18 is opened through the middle of the side wall of the limiting plate 6; specifically, the setting of the limiting plate 6 prevents the warning tape 16 from completely entering the disc-shaped shell 4 when the warning tape 16 is stored, and the setting of the screw hole 18 facilitates the installation and fixing of the limiting plate 6 after the warning tape 16 is pulled out.

[0024] See also Figure 3-Figure 5 In the figure, the fastening mechanism includes an internal threaded tube 13 and a circular groove 19. The internal threaded tube 13 is connected to the middle of the bottom end of the square shell 5, and the inner wall of the internal threaded tube 13 is threadedly connected with a knob screw 14. The upper end of the knob screw 14 is fixedly connected with a circular plate 17. The upper end of the circular plate 17 is tightly fitted with the outer surface of the warning tape 16. The circular groove 19 is opened at the inner bottom end of the square shell 5 corresponding to the circular plate 17.

[0025] Working principle: When in use, place the device at the specified position. In order to make the device more firmly placed, the ground nails can be inserted into the four mounting holes 7 on the base plate 1 in turn to keep the device fixed to the ground (also to prevent the device from being pulled down when the warning tape 16 is pulled later). Then turn on the switch on the alarm 3 to achieve sound warning and flash warning (this is a well-known prior art and will not be elaborated on). Combined with the eye-catching reminder of the warning sign 2, the device has a good warning effect.

[0026] When it is necessary to further improve the warning effect to avoid accidents caused by idle people approaching during the maintenance of the substation, the knob screw 14 can be turned downward first, and the knob screw 14 will rotate downward in the inner wall of the internal threaded tube 13, and the knob screw 14 will drive the circular plate 17 to move downward while rotating, so that the upper end of the circular plate 17 can leave the warning belt 16, and the circular plate 17 will move down into the circular groove 19 on the square shell 5, and then the limit plate 6 is pulled away from the disc-shaped shell 4, and the limit plate 6 will drive the warning belt 16 to be pulled out of the square shell 5, and the warning belt 16 will also be pulled out of the square shell 5. The disc-shaped shell 4 rotates, and the warning tape 16 drives the rotating shaft 12 to rotate in the inner wall of the disc-shaped shell 4 until the warning tape 16 is pulled to the required position, and then the pulling of the limit plate 6 can be stopped, and then the knob screw 14 is turned upward to reset the circular plate 17, so that the warning tape 16 can be fixed between the upper end of the circular plate 17 and the inner top of the square shell 5 to prevent the warning tape 16 from continuing to rotate outward in the disc-shaped shell 4. The warning tape 16 located outside the disc-shaped shell 4 can always remain in a taut state after being tightened and fixed, so as to prevent the warning tape 16 from falling to the ground.

[0027] When the maintenance work is completed, the knob screw 14 is turned downward again to make the circular plate 17 leave the warning tape 16, and then the handle 10 is turned. The handle 10 will drive the turntable 9 to rotate, and the turntable 9 will drive the shaft 12 to rotate in the inner wall of the disc-shaped shell 4, so that the warning tape 16 can be rolled up into the disc-shaped shell 4. After the rolling is completed, the knob screw 14 is turned upward again to reset the circular plate 17 to prevent the warning tape 16 from being pulled out from the disc-shaped shell 4.

[0028] It should be noted that the device not only has the good warning effect provided by the warning sign 2 and the alarm 3, but can also use the warning tape 16 to prevent pedestrians from approaching and causing possible safety accidents, and the warning tape 16 is easy to retract and release, which is convenient for the storage and transportation of the device.

[0029] It should also be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device.
