Detailed implementation manner

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Example 1, please refer to Figures 1 to 5 , the present invention provides a technical solution: an ecological protection device for highly weathered rock slopes in highway engineering, including a guardrail body 1. Fixed members 101 are fixedly installed on both sides of the bottom of the guardrail body 1. Screw rods 102 are threadedly connected inside both fixed members 101. The outer surfaces of both screw rods 102 are threadedly connected inside the guardrail body 1. Crank handles 109 are fixedly installed on the tops of both screw rods 102. Sleeves 103 are movably sleeved on the outer surfaces of both fixed members 101. First chutes 104 are opened on both sides inside both fixed members 101. The inner sides of the inner walls of both sleeves 103 are slidably connected to the inner surfaces of the first chutes 104. The outer surfaces of the bottoms of both screw rods 102 are movably embedded in the bottom sides of the inner walls of the sleeves 103. Multiple support rods 105 are movably connected to the outer surfaces of both sleeves 103. Multiple support rods 105 are divided into multiple groups in pairs. The other ends of multiple groups of support rods 105 are movably connected to fixed plates 108. Multiple second chutes 106 are opened at the bottoms of both fixed members 101. Slide blocks 107 are slidably connected to the inner surfaces of multiple second chutes 106. A connecting member 2 is fixedly installed on the top of the guardrail body 1. The bottoms of multiple slide blocks 107 are fixedly installed on the tops of the fixed plates 108. A connecting groove 201 is opened inside the connecting member 2.

[0032] In this embodiment, the personnel first open a notch on the ground and embed the fixing member 101 into the notch to fix the guardrail body 1. When used for a long time and the notch gradually expands and the fixing member 101 becomes loose inside the notch, the personnel can rotate the crank 109 to drive the screw 102 to rotate, so that the screw 102 can slide upward inside the fixing member 101. At the same time, the sleeve 103 is pulled upward by the screw 102, so that the sleeve 103 moves upward through the first chute 104. Then, the sleeve 103 slides upward on the outer surface of the fixing member 101. When the sleeve 103 slides upward, it will push the fixing plate 108 outward through the support rod 105, and drive the slider 107 to slide outward inside the second chute 106 through the fixing plate 108. Then, the fixing plate 108 can expand outward. When the fixing plate 108 expands to a certain extent, the outer surface of the fixing plate 108 will fit against the inner wall of the notch, and then re-fixation is carried out. And through structures such as the screw 102 and the fixing plate 108, not only can the position of the fixing plate 108 be adjusted to make it closely adhere to the inner wall of the notch, effectively improving the stability of the protection device and preventing loosening problems caused by notch expansion, but also the operator only needs to rotate the crank 109 to adjust the position of the fixing plate 108, without re-opening the notch or replacing the fixing member 101, simplifying the maintenance process.

[0033] Embodiment 2, as Figures 1 to 5 shown, a plurality of movable rods 202 are movably embedded inside the connecting member 2. A return spring 203 is fixedly installed at the top of each of the plurality of movable rods 202. The inner surfaces of the plurality of return springs 203 are movably sleeved on the outer surface of the movable rod 202. A connecting column 204 is fixedly installed on the right side of the top of the guardrail body 1. The other ends of the plurality of return springs 203 are fixedly installed on the top of the connecting member 2. A positioning groove 206 is opened on the left side of the guardrail body 1. A plurality of fixing grooves 205 are opened inside the connecting column 204. A positioning post 207 is fixedly installed on the right side of the guardrail body 1. The positioning post 207 matches the positioning groove 206. Each of the plurality of movable rods 202 matches the fixing groove 205.

[0034] In this embodiment, the staff can pick up another guardrail body 1 and place it on the left side of the first guardrail body 1 first, then pull up the movable rod 202 to drive the extension of the return spring 203, and push the additional guardrail body 1 to the right, so that the positioning column 207 is embedded into the positioning groove 206, and at the same time the connecting column 204 is embedded into the connecting groove 201 inside the connecting piece 2. After that, release the movable rod 202 to make the return spring 203 reset, and then drive the movable rod 202 to slide downward through the return spring 203, so that the movable rod 202 is embedded into the fixing groove 205 to fix the two guardrail bodies 1 and complete the splicing. And through the connecting piece 2 and the positioning column 207 and other structures, the operator only needs simple operation steps to realize the splicing between the guardrail bodies 1 without using additional tools, which simplifies the installation process and improves the installation efficiency.

[0035] Working principle: When in use, the operator first opens a notch on the ground and embeds the fixing member 101 into the notch to fix the guardrail body 1. When used for a long time and the notch gradually expands and the fixing member 101 becomes loose inside the notch, the operator can rotate the crank 109 to drive the screw rod 102 to rotate, so that the screw rod 102 can slide upward inside the fixing member 101. At the same time, the screw rod 102 pulls the sleeve 103 upward, causing the sleeve 103 to move upward through the first chute 104, and then the sleeve 103 slides upward on the outer surface of the fixing member 101. When the sleeve 103 slides upward, it will push the fixing plate 108 outward through the support rod 105, and drive the slider 107 to slide outward inside the second chute 106 through the fixing plate 108, so that the fixing plate 108 can expand outward. When the fixing plate 108 expands to a certain extent, the outer surface of the fixing plate 108 will fit against the inner wall of the notch, and then re-fix. And through structures such as the screw rod 102 and the fixing plate 108, not only can the position of the fixing plate 108 be adjusted to make it closely adhere to the inner wall of the notch, effectively improving the stability of the protection device and preventing loosening problems caused by notch expansion, but also the operator only needs to rotate the crank 109 to adjust the position of the fixing plate 108, without re-opening the notch or replacing the fixing member 101, simplifying the maintenance process. When in use, the operator can pick up another guardrail body 1, place it on the left side of the first guardrail body 1 first, then pull the movable rod 202 upward to drive the reset spring 203 to extend, and push the additional guardrail body 1 to the right, so that the positioning post 207 is embedded into the positioning groove 206, and at the same time the connecting post 204 is embedded into the connecting groove 201 inside the connecting member 2. Then release the movable rod 202, so that the reset spring 203 resets, and then drive the movable rod 202 to slide downward through the reset spring 203, so that the movable rod 202 is embedded into the fixing groove 205 to fix the two guardrail bodies 1 and complete the splicing. And through structures such as the connecting member 2 and the positioning post 207, the operator only needs simple operation steps to realize the splicing between the guardrail bodies 1, without using additional tools, simplifying the installation process and improving the installation efficiency.

[0036] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
