[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a fixing mechanism for a river guardrail, comprising a base 1, positioning blocks 2 are symmetrically fixedly connected on both sides of the base 1, mounting holes 3 are opened in the middle of the two positioning blocks 2, an anti-collision component is fixedly connected to one side of the middle of the base 1, the anti-collision component comprises a first spring 6, one end of the first spring 6 is fixedly connected to an arc-shaped baffle 7, a fixing block 8 is fixedly connected to one side of the middle of the base 1 and located at the center of the first spring 6, a second spring 9 is fixedly connected to the inner side wall of the fixing block 8, a push block 10 is fixedly connected to one end of the second spring 9, and the push block 10 is away from the first spring 6. A connecting rod 11 is fixedly connected to one side of the second spring 9, and the end of the connecting rod 11 away from the push block 10 is fixedly connected to the arc baffle 7. The arc baffle 7 and the base 1 are buffered by the first spring 6 to reduce the impact force on the base 1. At the same time, another part of the impact force will drive the connecting rod 11 and the push block 10 to perform secondary buffering and shock absorption on the second spring 9 in the fixed block 8. The overall structure is simple, can greatly reduce the impact force on the base 1, effectively prevent the base 1 from loosening, thereby reducing the impact on the guardrail base and enhancing the overall safety and stability of the device.

[0024] like Figure 1-4 As shown, a main rod 4 is fixedly connected to the axis center of the upper surface of the base 1, and the main rod 4 has a built-in lifting assembly. The lifting assembly includes a threaded rod B21 rotatably connected to the inner bottom wall of the main rod 4, a grinding block 23 is threadedly connected to the surface of the main rod 4, a spur gear B22 is fixedly connected to the surface of the threaded rod B21 near the lower position, a connecting block 13 is fixedly connected to one side of the main rod 4 near the position of the spur gear B22, an electric motor 19 is fixedly connected to the inner top wall of the connecting block 13, and the output shaft of the electric motor 19 is transmission-connected to the spur gear A 20, and the spur gear A20 and the spur gear B22 are meshed with each other, the output shaft of the electric motor 19 drives the spur gear A20 to rotate, and the spur gear A20 drives the spur gear B22 to rotate through the spur gear B22. Since the grinding block 23 rotates threadedly in the threaded rod B21, the threaded rod B21 will drive the grinding block 23 to rise when it rotates in the forward direction, and the grinding block 23 drives the sleeve rod 5 to slide and rise in the main rod 4, so as to adjust the height of the guardrail in real time according to actual needs. The device is more convenient to use and suitable for large-scale promotion.

[0025] like Figure 1-4As shown, the inner cavity of the main rod 4 is movably connected to the sleeve rod 5, and the surface of the main rod 4 is symmetrically fixedly connected with a plurality of equidistantly arranged buckles 12. Due to the arrangement of the buckles 12, the guardrail can be fixed without raising the height of the guardrail, and the actual application range of the guardrail is wider.

[0026] like Figure 1-4 As shown, a through hole 18 for sleeve connection with the threaded rod B21 is provided at the bottom of the sleeve rod 5, and a groove 14 is symmetrically provided on the outer surface of the sleeve rod 5. The inner wall of the groove 14 is symmetrically fixedly connected with a plurality of equidistantly arranged support blocks 16. A threaded rod A15 is threadedly connected to the inner side of the inner cavity of the sleeve rod 5 near the groove 14, and a displacement block 17 is threadedly connected to the middle part of the threaded rod A15. The distance between each displacement block 17 and the support block 16 is consistent. When the height of the guardrail is adjusted to a certain height, the buckle 12 cannot install the guardrail after the height is raised. The threaded rod A15 rotates in the sleeve rod 5 and drives multiple groups of displacement blocks 17 to move downward, thereby fixing one end of the guardrail on the upper surface of the support block 16, thereby fixing the guardrail after the height is adjusted.

[0027] Working principle:

[0028] When in use, first place the base 1 at the edge of the river channel, point one side of the arc baffle 7 toward oneself, and fix the expansion bolt through the mounting hole 3 in the ground to fix the base 1. There are falling rocks near the river channel. When the falling rocks hit the base of the guardrail, they will be blocked by the arc baffle 7. The arc baffle 7 and the base 1 are buffered by the first spring 6 to reduce the impact force on the base 1. At the same time, another part of the impact force will drive the connecting rod 11 and the push block 10 to perform secondary buffering and shock absorption on the second spring 9 in the fixing block 8. The overall structure is simple, which can greatly reduce the impact force on the base 1, effectively prevent the base 1 from loosening, and make the device safer when in use.

[0029] When installing the guardrail, the guardrail is clipped into the buckle 12, and the output shaft of the electric motor 19 drives the spur gear A20 to rotate, and the spur gear A20 drives the spur gear B22 to rotate through the spur gear B22. Since the grinding block 23 rotates in the threaded rod B21, the threaded rod B21 will drive the grinding block 23 to rise when it rotates in the forward direction, and the grinding block 23 drives the sleeve rod 5 to slide and rise in the main rod 4, so as to adjust the height of the guardrail in real time according to actual needs. When installing the guardrail after the height adjustment, place the two ends of the guardrail on the upper surface of the support block 16, rotate the threaded rod A15, and the threaded rod A15 rotates in the sleeve rod 5 and drives multiple groups of displacement blocks 17 to move downward, thereby fixing one end of the guardrail on the upper surface of the support block 16. Due to the self-locking function of the thread, the fixed guardrail is limited to prevent the fixed guardrail from loosening.
