However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1

[0025] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a road slope protection device, including a frame 1, the bottom surface of the frame 1 is fixedly installed with support feet 12, and the support feet 12 are symmetrically distributed on the bottom surface of the frame 1. The material of the support feet 12 can be high-strength steel or corrosion-resistant alloy to ensure that the protection device can be stably supported on various terrains. At the same time, for the connection method of the support feet 12, welding, bolt connection or riveting fixing methods can be adopted, and these connection methods can ensure the stability and durability between the support feet 12 and the frame 1. A protective net 2 is fixedly installed inside the frame 1, and the protective net 2 plays a role in blocking and protection. It is made of high-strength metal wire mesh or plastic mesh and can effectively resist the intrusion of external objects. A side block 3 is fixedly installed on the side surface of the frame 1, a slot 4 is opened on the side surface of the side block 3, a groove 5 is opened on the inner wall of the slot 4, a sliding rod 6 is penetrated through the inside of the groove 5, and the sliding rod 6 is slidably connected with the groove 5. This sliding connection method can adopt lubricating materials or sliding bearings to reduce friction and ensure the smooth movement of the sliding rod 6.

[0026] Please refer to Figures 1 - 5 , one end of the sliding rod 6 is fixedly installed with a limit block 7, a slope 8 is opened on one side of the limit block 7, a spring 9 is sleeved on the surface of the sliding rod 6, one end of the spring 9 is fixedly connected with the limit block 7, and the other end of the spring 9 is fixedly connected with the inner wall of the groove 5. Due to the elastic force of the spring 9, the spring 9 can drive the limit block 7 to move until the limit block 7 enters the slot 4. At this time, the side surface of the limit block 7 blocks the insertion rod 11, and then the insertion rod 11 can be limited, thus completing the splicing of two adjacent protective nets 2. A connecting plate 10 is fixedly installed on the side surface of the frame 1, an insertion rod 11 is fixedly installed on the side surface of the connecting plate 10, and the insertion rod 11 is adapted to the size of the slot 4. After the insertion rod 11 enters the slot 4, the insertion rod 11 can move up and down in the slot 4. In this way, when splicing multiple protective nets 2, it can adapt to uneven terrains. The material of the insertion rod 11 can be steel, aluminum alloy or other durable materials to ensure that it can withstand long-term use without deformation.

[0027] Embodiment Two

[0028] Please refer to Figures 4 - 5, an expansion mechanism is provided on the surface of the frame 1. The expansion mechanism includes a vertical groove 13 which is opened on the surface of the frame 1. A short block 14 is slidably connected to the inner wall of the vertical groove 13, and an expansion guard plate 15 is fixedly installed on the surface of the short block 14. To improve the reliability and durability of the sliding connection, the vertical groove 13 and the short block 14 can be made of high-strength plastic or stainless steel. These materials ensure the stability during sliding and the corrosion resistance under long-term use. In addition, the sliding connection method can also adopt linear bearings or ball screws, etc., to reduce friction and improve the smoothness and efficiency of sliding. A lead screw 16 is rotatably connected to the inner wall of the vertical groove 13, and a thread is opened inside the short block 14, and the thread meshes with the lead screw 16. The rotational connection method is a typical lead screw-nut mechanism, which can not only achieve precise linear movement but also facilitate the transmission and conversion of force. A hexagonal cap 17 is fixedly installed at the top of the lead screw 16. By turning the hexagonal cap 17, the rotation of the lead screw 16 can be controlled, so as to realize the precise position adjustment of the short block 14 in the vertical groove 13. The lead screw 16 and the hexagonal cap 17 are usually made of high-strength steel to ensure their load-bearing capacity and durability.

[0029] Working principle: The set protective net 2 can play a role in blocking and protecting. When assembling and using multiple protective nets 2, the staff only needs to align the insertion rod 11 on an adjacent set of protective nets 2 with the insertion slot 4 and insert it. After the insertion rod 11 is completely inserted into the insertion slot 4, due to the elastic force of the spring 9, the spring 9 can drive the limit block 7 to move until the limit block 7 enters the insertion slot 4. At this time, the side of the limit block 7 blocks the insertion rod 11, and then the insertion rod 11 can be limited, thus completing the splicing of two adjacent protective nets 2. And after the insertion rod 11 enters the insertion slot 4, the insertion rod 11 can move up and down in the insertion slot 4. In this way, when splicing multiple protective nets 2, it can adapt to uneven terrains. The utility model can conveniently splice multiple protective nets 2, and through the design that the insertion rod 11 can move up and down in the insertion slot 4, the protective net 2 can adapt to various uneven terrains, which is particularly important for the protection of irregular slopes. Such a design can ensure that each protective net 2 can still closely fit the ground under the condition of uneven ground, providing a continuous and stable protection effect. Since it can adapt to different terrains, the installation staff has greater flexibility during installation and can adjust the position of each component of the protective net 2 according to the actual terrain conditions. Through the set expansion guard plate 15, by default, the expansion guard plate 15 coincides with the protective net 2 for use. When there are requirements for the protection height, the staff can turn the screw rod 16 by the hexagonal cap 17. At this time, since the short block 14 is provided with threads, the screw rod 16 can synchronously drive the short block 14 to slide in the vertical groove 13, and the short block 14 then drives the expansion guard plate 15 to move until the expansion guard plate 15 rises. At this time, the protection height can be increased through the expansion guard plate 15. The utility model can be flexibly adjusted according to the actual protection height requirements, is applicable to a variety of occasions and environments, increases the application range of the protection device, and the staff only needs to turn the screw rod 16 by the hexagonal cap 17 to achieve height adjustment. The operation is simple and convenient, without the need to replace the protective net 2 or add additional components, greatly improving the installation and adjustment efficiency. When additional protection height is not required, the expansion guard plate 15 can coincide with the protective net 2, maintaining the cleanliness and beauty of the protection device.
