[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 4 As shown, a grounding protection device for broadcasting engineering includes:

[0027] A first tube body 1, with a second tube body 11 movably connected to one side of the first tube body 1;

[0028] Split assembly 2 is disposed on one side of the first tube 1 and the second tube 11. Split assembly 2 includes a plug rod 21 fixedly installed on one side of the first tube 1, a slot 22 opened on the side of the second tube 1 near the first tube 1, locking grooves 23 symmetrically installed on both sides of the first tube 1, L-shaped rods 24 movably installed on both sides of the second tube 1, and two connectors 27 fixedly installed on the side of the first tube 1 near the locking groove 23, with a pressure rod 210 movably installed between the two connectors 27.

[0029] The buffer assembly 3 is disposed on one side of the top end of the first tube 1 and the second tube 11. The buffer assembly 3 includes a frame 31 fixedly installed at the top end of the first tube 1 and the second tube 11. A column 32 is movably installed inside the frame 31. A buffer plate 34 is fixedly installed at the top end of the column 32. A first spring 33 is connected between the column 32 and the frame 31.

[0030] Specifically, the insertion rod 21 is correspondingly set with the slot 22, and the insertion rod 21 slides against the inner wall of the slot 22. The L-shaped rod 24 is correspondingly set with the locking groove 23. A pull block 25 is fixedly installed at the end of the L-shaped rod 24 away from the locking groove 23. Two limiting rings 26 are movably connected to the outer wall of the L-shaped rod 24. The two limiting rings 26 are fixedly connected to the second tube 11 on the side near the outer wall of the second tube 11. Two connecting pieces 27 are fixedly installed on the outer side of the first tube 1 near the locking groove 23. A rotating shaft 28 is movably installed between the two connecting pieces 27 through a bearing. Two rotating blocks 29 are fixedly installed on the outer side of the rotating shaft 28. A pressure rod 210 is connected between the two rotating blocks 29. A torsion spring 211 is connected between the two rotating blocks 29 and the connecting piece 27. The torsion spring 211 is located on the outer side of the rotating shaft 28.

[0031] As can be seen from the above, inserting the rod 21 into the slot 22 enhances the strength of the connection between the two tubes. The limiting ring 26 provides a limiting effect for the L-shaped rod 24. Under the action of the torsion spring 211, the pressure rod 210 will always remain pressed on one side of the L-shaped rod 24 to prevent the L-shaped rod 24 from flipping to one side.

[0032] Example 2:

[0033] Please see Figure 1 - Figure 3 and Figure 5 As shown, a frame 31 is fixedly installed on one side of the top of the first tube 1 and the second tube 11. A column 32 is movably installed inside the frame 31. The column 32 slides against the inner wall of the frame 31. A first spring 33 connects the column 32 and the inner wall of the frame 31. A buffer plate 34 is fixedly installed on the top of the column 32.

[0034] Specifically, auxiliary frames 35 are symmetrically installed on both sides of the frame 31. A limit rod 36 is fixedly installed inside the auxiliary frame 35. A limit block 37 is movably sleeved on the outside of the limit rod 36. A second spring 38 is connected between the limit block 37 and the inner wall of the auxiliary frame 35. The second spring 38 is located outside the limit rod 36. A sliding groove 39 is opened on the outside of the frame 31 near the auxiliary frame 35. A slider 310 is movably installed inside the sliding groove 39. The slider 310 slides and fits against the inner wall of the sliding groove 39. The side of the slider 310 near the inside of the frame 31 is fixedly connected to the column 32. A push rod 311 is hinged between the slider 310 and the limit block 37.

[0035] As can be seen from the above, when the buffer plate 34 is subjected to the pressure of the ground, it will transfer part of the energy to the first spring 33, thereby achieving the buffering effect. The auxiliary frame 35 and the limiting rod 36 can limit the limiting block 37. During the descent, the column 32 will also drive the limiting block 37 to move inside the auxiliary frame 35 through the push rod 311, thereby driving the second spring 38 to deform, thereby further improving the buffering capacity of the device.

[0036] This application can be applied to urban underground utility tunnels. In broadcasting engineering, underground utility tunnels are not only important channels for signal transmission, but also key facilities for protecting broadcasting lines from external interference and damage. The specific steps for using this device are as follows:

[0037] S1. First, conduct a survey of the actual situation of the underground utility tunnel, including factors such as the tunnel's structure, size, environmental humidity, and corrosivity, in order to determine the specific requirements and installation location of the grounding protection device.

[0038] S2, clean up debris and dust around the installation location to ensure a clean installation environment;

[0039] S3, insert the insertion rod 21 into the slot 22, and at the same time, slide the L-shaped rod 24 into the locking groove 23. Pull the pressure rod 210 outward, and then rotate the L-shaped rod 24 upward so that the L-shaped rod 24 is completely in contact with the locking groove 23. Then release the pressure rod 210. The pressure rod 210 will be pressed against one side of the L-shaped rod 24 under the action of the torsion spring 211. At this time, the L-shaped rod 24 will not swing to one side, and the tube assembly is completed.

[0040] S4. Use special clamps or brackets to fix the device in the designated position in the underground utility tunnel. During the fixing process, pay attention to maintaining the horizontal and verticality of the device to avoid tilting or twisting.

[0041] S5. Regularly inspect and maintain the device, including checking the sealing of the plug structure, the performance of the shock absorption system, and the corrosion of the pipe body.
