[0035] With reference to the drawings and embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application. Figure 1 , Figure 3 and Figure 5The inner wall of the connecting cap 13 is fixedly connected with the upper adjusting rod 14, which plays a role in supporting the whole device. The inner wall of the other connecting cap 13 is fixedly connected with the lower adjusting rod 15, which plays a role in supporting the whole device together with the upper adjusting rod 14. The other end of the upper adjusting rod 14 is rotatably connected with the lifting ring 19, which controls the opening and folding of the upper adjusting rod 14. The other end of the lower adjusting rod 15 is rotatably connected with the fixing sleeve 17, which plays a certain fixing role. The inner wall of the lifting ring 19 is slidably connected with the middle column 16, which provides support and guidance for the sliding action of related components in the whole device.

[0036] The inner wall of the middle column 16 is fixedly connected with the reset spring 20, the other end of which is fixedly connected with the limiting ball 18. The reset spring 20 can drive the limiting ball 18 to block the position of the lifting ring 19. The reset spring 20 can provide elastic force under certain conditions, and the outer wall of the limiting ball 18 is slidably connected to the inner wall of the lifting ring 19. When the lifting ring 19 slides to a certain position, the limiting ball 18 can block the lifting ring 19 to fix the lifting ring 19. The outer wall of the other connecting plate 5 is fixedly connected to the inner wall of the outer support plate 9, further stabilizing the connection relationship between the outer support plate 9 and other components. The bottom of the connecting column 21 is fixedly connected with the ground insertion cone 10, which is directly inserted into the ground to contact the soil and fix the device. The top of the connecting column 21 is fixedly connected to the top of the threaded column 2, ensuring the coherence of the whole device structure. The outer wall of the upper adjusting rod 14 is provided with a canvas 22, and the inner wall of the canvas 22 is provided on the outer wall of the lower adjusting rod 15. The canvas 22 can play a certain shielding role here, such as preventing foreign matter from entering the inside of the device.

[0037] Working principle: when the shielding device needs to be placed in the pit of power grid construction, the shielding device is opened, and then the ground insertion cone 10 is inserted into the ground below the pit of construction, and then the rotating handle 8 is rotated, which drives the rotating sleeve 3 to displace downward. During the displacement, the displacement of the rotating sleeve 3 drives the sliding plate 23 to also displace downward. The rotating sleeve 3 continuously slides in the inside of the sliding plate 23 during rotation. At this time, the downward movement of the sliding plate 23 drives the upper rotating plate and the lower rotating plate to be opened, which drives the outer wall of the upper rotating plate and the lower rotating plate to be opened together through the connecting plate 5 connected with the outer support plate 9 to be opened to the four directions, so as to expand the contact area of the ground insertion cone 10 with the soil under the ground, so that the shielding device is fixed more firmly.

[0038] Regarding the opening of the shielding device, first, the lifting ring 19 slides on the outer wall of the center column 16. Since the lower adjusting rod 15 is fixed to the bottom end fixed sleeve 17 of the center column 16, the sliding of the lifting ring 19 will drive the lower adjusting rod 15 to be stretched outwards. The stretching outwards of the lower adjusting rod 15 drives the connecting block 12 to be stretched outwards. The stretching outwards of the connecting block 12 drives the lower adjusting rod 15 to be stretched outwards. When the lower adjusting rod 15 and the upper adjusting rod 14 are completely stretched outwards, the connecting sleeve 11 at the end of the connecting block 12 is used to install the stand 1 and the ground insertion rod, so as to facilitate the stable fixation of the entire device in the construction pit. When the lifting ring 19 slides to a certain position of the center column 16, it will contact the limiting ball 18. The limiting ball 18 clamps the lifting ring 19 to fix the lifting ring 19, thereby completing the opening of the device.
