[0013] Example 1, by Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model relates to a protective fence for a river embankment, including a support plate 1. Support seats 2 are fixedly installed at the bottom of both ends of the support plate 1, and mounting holes 3 are opened through both ends of the bottom of the support seats 2. In use, mounting bolts that are compatible with the diameter of the mounting holes 3 are used to fix the support seats 2 to achieve the fixed installation of the entire protective fence and facilitate operation. Connecting plates 24 are fixedly installed at the top of both ends of the support plate 1, and three connecting holes 25 are opened through the interior of each of the two connecting plates 24. In use, through the interaction between the connecting plates 24 and the connecting holes 25, connecting bolts that are compatible with the diameter of the connecting holes 25 and connecting nuts can be used to connect two adjacent sets of protective fences, thereby facilitating better construction of the entire protective fence for the river embankment. Hollow columns 4 are symmetrically fixedly installed on the top of the support plate 1. A positioning plate 5 is fixedly installed between the tops of two hollow columns 4. Square sleeves 6 are evenly penetrated inside the positioning plate 5, and the bottom of the square sleeves 6 is fixedly connected to the top of the support plate 1. A shielding frame 7 is fixedly installed between two adjacent square sleeves 6. A square support column 8 is slidably installed inside the square sleeve 6, and the top of the square support column 8 extends above the top of the square sleeve 6. A movable frame 9 is fixedly installed on the top of the square support column 8. An adjustment component 10 is fixedly installed at the bottom of the support plate 1, and the tops of both ends of the adjustment component 10 penetrate through the hollow columns 4 and are connected to the bottoms of both ends of the movable frame 9. During use, through the interaction of the support plate 1, support base 2, mounting hole 3, hollow column 4, positioning plate 5, square sleeve 6, shielding frame 7, square support column 8, movable frame 9 and adjustment component 10, the height of the protective fence along the river embankment can be adjusted according to actual needs, improving its adaptability and thus facilitating better practicality. The adjusting assembly 10 includes a strip frame 11, which is fixedly installed at the bottom of the support plate 1. An adjusting shaft 12 is rotatably mounted inside the strip frame 11, and both ends of the adjusting shaft 12 extend to the outside of the strip frame 11. An adjusting block 13 is fixedly installed at one end of the adjusting shaft 12, and a limit block 14 is fixedly installed at the other end. A locking thread 15 is provided on the outer side of the end of the adjusting shaft 12 away from the adjusting block 13. A locking nut 16 is installed on the outer thread of the locking thread 15, and one side of the locking nut 16 contacts the outer side of the strip frame 11. During use, the adjusting screw 19 can be positioned or released by loosening or tightening the locking nut 16, which is convenient for operation. This also ensures the stability of the structure. Inside the strip frame 11 and outside the adjusting shaft 12, two active bevel gears 17 are fixedly installed. The outer sides of the two active bevel gears 17 are meshed with driven bevel gears 18. An adjusting screw 19 is fixedly installed on the top of the driven bevel gear 18. The top of the adjusting screw 19 extends into the interior of the hollow column 4. Two positioning bearings 20 are rotatably installed on the outer side of the bottom end of the adjusting screw 19. The two positioning bearings 20 are fixedly installed on the top and bottom of the support strip 1, respectively. Inside the hollow column 4 and outside the adjusting screw 19, a threaded sleeve 21 is threadedly installed. The top of the threaded sleeve 21 extends to the top of the hollow column 4 and is fixedly connected to the bottom of the movable frame 9. A positioning slider 22 is fixedly installed on the outer side of the bottom end of the threaded sleeve 21. A positioning groove 23 is opened through one side of the hollow column 4, and the positioning slider 22 is slidably installed inside the positioning groove 23. During use, the interaction between the positioning slider 22 and the positioning groove 23 makes it easier for the threaded sleeve 21 to achieve better stability when moving, thereby ensuring that the adjustment component 10 can work stably.

[0014] Working principle: During operation, the support base 2 is first fixedly installed using mounting bolts that match the diameter of the mounting hole 3, thereby achieving the fixed installation of the entire fence. Then, the locking nut 16 is loosened to release the positioning of the adjusting shaft 12. Then, the adjusting block 13 is rotated to drive the adjusting shaft 12 to rotate. The adjusting shaft 12 drives the two driving bevel gears 17 to rotate simultaneously. The driving bevel gears 17 drive the driven bevel gear 18 to rotate. The driven bevel gear 18 drives the adjusting screw 19 to rotate. The adjusting screw 19 drives the threaded sleeve 21 to move upward. The threaded sleeve 21 drives the positioning slider 22 to move in the positioning position. The sliding inside the groove 23 ensures better stability of the threaded sleeve 21 during movement. At the same time, the threaded sleeve 21 drives the movable frame 9 to move upward, and the movable frame 9 drives the square support 8 to slide upward inside the square sleeve. After the movable frame 9 moves to the required height, the rotation of the adjusting block 13 is stopped, and then the locking nut 16 is tightened to reposition the adjusting shaft 12, completing the overall height adjustment operation of the protective fence. This allows the height of the protective fence along the river embankment to be adjusted according to actual needs during use, improving its adaptability and thus facilitating better practicality.
