Description

Technical Field

[0001] This utility model relates to the field of water conservancy guardrail technology, specifically to a guardrail for water conservancy engineering facilities. Background Technology

[0002] Protective railings for water conservancy projects are railings or fences used to protect water conservancy facilities such as rivers, reservoirs, and canals. The main function of protective railings is to block and restrict the entry of people, animals, or floating objects into the water conservancy project area, ensuring the safe operation of the facilities and protecting the environment. According to application number CN222649631U, a water conservancy facility guardrail is constructed by means of guardrail support rods, auxiliary support rods, barbed wire frames, and guardrail isolation nets. These components make the guardrail installation more stable and allow for disassembly, replacement, and maintenance. When any one of these components is damaged, it can be disassembled and replaced individually, eliminating the need for complete replacement. This speeds up maintenance, saves on costs, and facilitates the upkeep of the guardrail. The support rods and auxiliary support rods ensure a more secure and stable installation. The barbed wire frames can be detached from the upper ends of the support rods to prevent people from climbing over the guardrail. The isolation nets can also be detached from the support rods to provide isolation. However, when patrol personnel discover that the isolation netting is broken and has gaps, they cannot take temporary measures to protect it in time. By the time maintenance personnel arrive to repair it, there will be a certain period of security gaps, which will allow people and animals to enter the water conservancy facilities through the security gaps.

One end of the wire mesh 7 extends to the outside of the winding box 3 and is fixedly connected to a traction bar 10. A first fixing block 8 is fixedly connected to the surface of the other mounting post 1. A through side groove 25 is opened on one side of the traction bar 10. The first fixing block 8 is located inside the side groove 25. A spring 17 is installed at the bottom of the inner cavity of the winding box 3. One end of the winding roller 6 is connected to the spring 17. A handle 24 is fixedly connected to one side of the traction bar 10.

[0022] The inner cavity of the traction bar 10 is slidably connected to the insert block 11. One end of the insert block 11 is inserted into the first fixing block 8. A spring 12 is fixedly connected to one side of the inner cavity of the traction bar 10. One end of the spring 12 is fixedly connected to one end of the insert block 11. The spring 12 pushes the insert block 11 to move.

[0023] A drive block 14 is fixedly connected to the surface of the traction bar 10, and a pulling block 13 is fixedly connected to one side of the insertion block 11. One end of the pulling block 13 extends to the outside of the drive block 14 and is fixedly connected to a buckle so that the pulling block 13 and the insertion block 11 can be moved by pulling the buckle.

[0024] A threaded groove 15 is provided on one side of the drive block 14. A second screw 16 is threadedly connected inside the threaded groove 15. One end of the second screw 16 extends into the traction bar 10 and contacts one end of the insert block 11. By contacting one end of the second screw 16 with one end of the insert block 11, the position of the insert block 11 is limited and fixed.

[0025] The other end of the second screw 16 extends to the outside of the drive block 14. Two threaded holes 23 are opened on one side of the mounting post 1. Mounting blocks 4 are fixedly connected to the top and bottom of the winding box 3. The first screw 5 is threaded inside the mounting block 4. One end of the first screw 5 extends into the threaded hole 23 and is threaded into the threaded hole 23. When the winding box 3 needs to be replaced, one end of the first screw 5 is unscrewed from the threaded hole 23, and then the winding box 3 is removed. The new winding box 3 is placed on one side of the mounting post 1, and one end of the first screw 5 is screwed into the threaded hole 23 to limit and fix the winding box 3.

[0026] Example 2

[0027] Please see Figures 1 to 2This utility model provides a technical solution: a base 2 is fixedly connected to the bottom of each mounting column 1, a protective net 18 is placed between two mounting columns 1, a second threaded block 21 is fixedly connected to the top and bottom of the protective net 18, a first threaded block 19 is fixedly connected to the inner side of each mounting column 1 and behind the second threaded block 21, a third screw 20 is threadedly connected inside each second threaded block 21, one end of each third screw 20 extends into the inside of the first threaded block 19 and is threadedly connected to the inside of the first threaded block 19, a second fixing block 22 is fixedly connected to one side of each mounting column 1, and the mounting column 1 can be fixed to the ground by screws through the base 2.

[0028] In summary, when the inspectors find that the protective netting 18 is damaged, they unscrew one end of the second screw 16 out of the threaded groove 15, then pull the traction block 13, causing the traction block 13 to move one end of the insert block 11 out of the second fixing block 22. Then, they pull the handle 24, causing the traction bar 10 to move in front of the surface of another mounting post 1, so that the traction bar 10 pulls the wire mesh 7 out from the outside of the winding roller 6. When the traction bar 10 moves to the outside of the first fixing block 8, the traction block 13 is released. At this time, the spring 12 pushes one end of the insert block 11 into the first fixing block 8. Then, the second screw 16 is screwed, so that one end of the second screw 16 contacts one end of the insert block 11, limiting and fixing the position of the insert block 11, thereby temporarily protecting the guardrail.

[0029] When maintenance personnel arrive at the fence with the new protective netting 18, they will unscrew one end of the second screw 16 out of the threaded groove 15, then pull the traction block 13, causing it to move one end of the insert block 11 out of the first fixing block 8. Next, they will pull the handle 24, moving the traction bar 10 to the front of the other mounting post 1. Then, they will release the traction block 13, at which point the spring 12 will push one end of the insert block 11 into the second fixing block 22. Finally, they will tighten the second screw 16, connecting one end of the second screw 16 with one end of the insert block 11. The position of the insert block 11 is limited and fixed, so that the spring 17 drives the winding roller 6 to reset and rotate, so that the winding roller 6 winds up the wire mesh 7. Then, one end of the third screw 20 is unscrewed from the inside of the first threaded block 19 and the second threaded block 21 to release the limitation and fixation of the protective net 18. Then, the protective net 18 is taken out from between the two mounting posts 1. Then, the new protective net 18 is placed between the two mounting posts 1. Then, one end of the third screw 20 is screwed into the inside of the second threaded block 21 and the first threaded block 19 to complete the limitation and fixation of the protective net 18.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
