[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Combination Figures 1-2 A safety guardrail for an environmental protection project includes a first support rod 1 and a second support rod 2. A guardrail assembly 3 is provided between the first support rod 1 and the second support rod 2. Grooves 5 are provided on the inner sides of both the first support rod 1 and the second support rod 2.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Please see Figures 2-6The railing assembly 3 includes a first connecting plate 31 fixedly connected to the bottom of the inner wall of the groove 5, a threaded rod 32 rotatably passing through the top of the first connecting plate 31, a sleeve rod 33 threadedly connected to the outer surface of the threaded rod 32, a second connecting plate 34 fixedly connected to the top of the sleeve rod 33, a telescopic rod 35 fixedly connected to the top of the first connecting plate 31, and a crank 36 fixedly connected to the bottom of the threaded rod 32. The telescopic end of the telescopic rod 35 is fixedly connected to the bottom of the second connecting plate 34. By rotating the crank 36, the threaded rod 32 is rotated, which causes the sleeve rod 33 to move up and down. The up and down movement of the sleeve rod 33 causes the second connecting plate 34 to move up and down. At this time, the telescopic rod 35 extends and retracts with the up and down movement of the second connecting plate 34 to maintain the overall stability of the railing assembly 3. The up and down movement of the second connecting plate 34 facilitates the adjustment of the distance between the first connecting plate 31 and the second connecting plate 34, thereby facilitating the adjustment of the height of the guardrail according to actual needs.

[0027] The inner wall of the groove 5 is provided with a sliding groove 51. A slider 341 is fixedly connected to one side of the second connecting plate 34. The slider 341 is slidably connected to the sliding groove 51. When the sleeve rod 33 moves up and down, driving the second connecting plate 34 to move up and down, the slider 341 slides along the sliding groove 51, which plays a guiding and limiting role, ensuring that the second connecting plate 34 always remains vertical during the up and down movement.

[0028] The bottom ends of the first support rod 1 and the second support rod 2 are both fixedly connected to the first support plate 6. The bottom end of the first support plate 6 is fixedly connected to the friction pad 61. The first support plate 6 provides a large contact area to enhance support stability. The friction pad 61 facilitates the increase of friction between the first support plate 6 and the ground, further enhancing support stability.

[0029] A horizontal plate 12 is fixedly connected between the first support rod 1 and the second support rod 2. The outer surface of the horizontal plate 12 has a threaded groove 121. An anti-tipping component 8 is provided on the outer surface of the horizontal plate 12. The anti-tipping component 8 includes a threaded post 81 threadedly connected to the inside of the threaded groove 121, a connecting post 82 fixedly connected to the bottom end of the threaded post 81, a fixing plate 83 fixedly connected to the outer surface of the connecting post 82, and a second support plate 84 fixedly connected to one end of the fixing plate 83. A limit nut 9 is provided on the outer surface of the threaded groove 121. The horizontal plate 12 is located directly below the first connecting plate 31. By tightening the limit nut 9, the threaded post 81 is fixed inside the threaded groove 121, ensuring that the second support plate 84 is in contact with the ground and remains stable. At this time, the second support plate 84 provides additional lateral support to enhance the overall stability of the guardrail, prevent the guardrail from tilting or tipping over, and improve safety.

[0030] A first connecting block 11 is fixedly connected to one side of the first support rod 1. A limiting post 111 is fixedly connected to the bottom end of the first connecting block 11. A second fixing block 21 is fixedly connected to one side of the second support rod 2. A limiting groove 211 is opened at the top of the second fixing block 21. The limiting post 111 is correspondingly set with the limiting groove 211. A locking bolt 212 is threaded between the limiting post 111 and the second fixing block 21. The limiting post 111 is inserted into the limiting groove 211, and then the locking bolt 212 is used to fix the limiting post 111 inside the limiting groove 211 to ensure the firmness of the connection point and prevent loosening or falling off due to external force. At the same time, it is convenient to connect multiple sets of guardrails and to adjust the length of the guardrail as needed.

[0031] Both the first support rod 1 and the second support rod 2 are equipped with batteries. Both the first support rod 1 and the second support rod 2 are equipped with lights 7 at their top ends. The batteries are electrically connected to the lights 7. In the event of night or insufficient light, the lights 7 can provide necessary lighting to prevent pedestrians or vehicles from accidentally entering.

[0032] Reflective strips 4 are fixedly connected to the outer surfaces of both the first connecting plate 31 and the second connecting plate 34. The reflective strips 4 can improve the visibility of the guardrail at night or in low light conditions.

[0033] In use, rotating the crank 36 drives the threaded rod 32 to rotate, which in turn drives the sleeve rod 33 to move up and down. The sleeve rod 33 moves up and down, which in turn drives the second connecting plate 34 to move up and down. At this time, the telescopic rod 35 extends and retracts with the up and down movement of the second connecting plate 34 to maintain the overall stability of the railing assembly 3. The up and down movement of the second connecting plate 34 facilitates the adjustment of the distance between the first connecting plate 31 and the second connecting plate 34, thereby facilitating the adjustment of the height of the guardrail according to actual needs. By tightening the limit nut 9, the threaded post 81 is fixed inside the threaded groove 121, ensuring that the second support plate 84 is in contact with the ground and remains stable. At this time, the second support plate 84 provides additional lateral support to enhance the overall stability of the guardrail, prevent the guardrail from tilting or falling, and improve safety. The limit post 111 is inserted into the limit groove 211, and then the limit post 111 is fixed inside the limit groove 211 by the locking bolt 212, which facilitates the connection of multiple sets of guardrails and allows for adjustment of the length of the guardrail as needed.
