A grounding rod 12 is inserted through the top of the mounting plate 10.

[0030] In this embodiment: by setting...

[0031] The system includes a protective fence 1, with support rods 2 fixedly installed at both ends. There are two protective fences 1, and magnetic plates with magnetic attraction are installed at the connection points of the protective fences 1. Multiple hinges 3 are fixedly installed between the protective fences 1. Placement slots 4 are provided through the front and rear sides of the support rods 2, and installation mechanisms are installed in the placement slots 4. Multiple slots 5 are provided through the top of the protective fence 1. A movable cylinder 6 is threaded inside the support rods 2. A docking plate 7 of the same size as the support rods 2 is fixedly installed at the top of the movable cylinder 6. A heightening mechanism is provided at the bottom of the movable cylinder 6.

[0032] The mounting mechanism includes a rotating shaft 8 and a support plate 9. The rotating shaft 8 passes through the interior of the placement groove 4, and the support plate 9 is sleeved on its outer side. The support plate 9 is rotatably connected to the rotating shaft 8. A mounting plate 10 is fixedly installed at one end of the support plate 9. An anti-slip pad 11 is fixedly installed at the bottom of the mounting plate 10. A grounding rod 12 is inserted through the top of the mounting plate 10.

[0033] In this embodiment: by setting a magnetic suction plate, the two protective fence pieces 1 can be attracted together to achieve a fixing effect. By setting a pivot 8, it can drive the support plate 9 and the mounting plate 10 to rotate inside the placement slot 4, making the support design movable. When using the fence, the support plate 9 and the mounting plate 10 can be rotated out through the pivot 8, and the ground insertion rod 12 can be inserted through the mounting plate 10 to fix it to the ground. By setting an anti-slip pad 11, the stability of the connection between the mounting plate 10 and the ground can be enhanced, and the bottom ends of the support rod 2 can be locked horizontally. When transporting or storing the protective fence, by setting a hinge 3, the two protective fence pieces 1 can be separated, so that the protective fence pieces 1 are in a folded state, reducing a certain area. The support plate 9 and the mounting plate 10 can be flipped into the placement slot 4 and attached to a vertical state, which can greatly reduce the overall volume of the protective fence, occupy less space, and is more conducive to the transportation and storage of the protective fence.

[0034] The heightening mechanism includes a screw 13 and a main bevel gear 14. The main bevel gear 14 is fixedly installed at the bottom of the screw 13. A secondary bevel gear 15 is meshed on one side of the main bevel gear 14. A turntable 16 is fixedly installed on one side of the secondary bevel gear 15, and one end of the turntable 16 extends through to the outside of the support rod 2. The interior of the protective fence 1 is provided with a telescopic groove 17. A reinforcing plate 18 is provided inside the telescopic groove 17. Multiple anti-climbing rods 19 are fixedly installed on the top of the reinforcing plate 18.

[0035] In this embodiment: the turntable 16 drives the secondary bevel gear 15 to rotate, which in turn drives the main bevel gear 14 to mesh, thereby driving the screw 13 to rotate. The screw 13, through the transmission of the thread, drives the moving cylinder 6 to move up and down inside the support rod 2. The moving cylinder 6, during its movement, can drive the reinforcing plate 18 to move synchronously, and the reinforcing plate 18 drives multiple anti-climbing rods 19 to move up to the top of the slot, thereby increasing the overall height of the protective fence 1 and preventing pedestrians from climbing. The height of the protective fence can be adjusted according to the engineering protection height and needs, thereby improving the convenience of using the protective fence.

[0036] A movable groove 23 is provided through the connection between the support rod 2 and the expansion groove 17. One end of the reinforcing plate 18 passes through the movable groove 23 and is fixedly connected to the support rod 2. The reinforcing plate 18 and the inner wall of the expansion groove 17 are slidably connected through a groove structure.

[0037] In this embodiment: by setting the movable groove 23, the movable cylinder 6 can drive the reinforcing plate 18 to move up and down inside it, so that its movement is not restricted. At the same time, by using the sliding method of the concave and convex groove structure, the sliding between the reinforcing plate 18 and the telescopic groove 17 is smoother and more stable.

[0038] The diameter of the anti-climb rod 19 is smaller than that of the slot 5, and the anti-climb rod 19 is movably connected to the slot 5. The bottom of the support rod 2 is fixedly equipped with a movable wheel 20.

[0039] In this embodiment: the protective fence 1 can be easily moved by the movable wheels 20, and the anti-climb pole 19 can be easily stored and protected when not in use by the slot 5, so as to avoid the sharp point of the anti-climb pole 19 from accidentally injuring the staff.

[0040] The connection length of the support plate 9 and the mounting plate 10 matches the placement groove 4, and the support plate 9 is rotatably connected to the placement groove 4 through the rotating shaft 8.

[0041] In this embodiment, by connecting the support plate 9 and the mounting plate 10 with a length less than that of the placement groove 4, the placement groove 4 can accommodate the support plate 9 and the mounting plate 10, and the rotating shaft 8 can drive the support plate 9 to rotate inside the placement groove 4.

[0042] One end of one support rod 2 is fixedly provided with a connector 21, and the other end of the support rod 2 is fixedly provided with a connector block 22. The diameter of the connector block 22 is the same as the inner diameter of the connector 21. The top of the connector 21 and the connector block 22 are both provided with matching screw holes.

[0043] In this embodiment, by setting the plug-in socket 21 and the plug-in block 22, the fixing of multiple protective fences 1 can be achieved.

[0044] The implementation principle of the safety protection fence embodiment for water conservancy and hydropower projects in this application is as follows:

[0045] S1. During installation, first move the protective fence 1 to the outside of the water conservancy and hydropower project that needs protection using the moving wheels 20. Then, flip the support plate 9 located in the placement groove 4 out using the rotating shaft 8 until the bottom of the mounting plate 10 is in contact with the ground. Then, insert the ground rod 12 through the mounting plate 10 and insert it into the soil to lock it in place, thus completing the installation and fixing of the protective fence 1. When installing multiple protective fences 1, connect the multiple protective fences 1 through the insertion of the insertion seat 21 and the insertion block 22, and fix them with external bolts to achieve the fixing of multiple protective fences 1.

[0046] S2. During transportation, repeat the above steps to flip the mounting plate 10 and support plate 9 into the placement slot 4 and attach them in a vertical position. Then, flip the two protective fences 1 using the hinge 3 and separate the two magnetic plates at the connection of the two protective fences 1, so that the two protective fences 1 are in a folded state. Finally, move them using the moving wheels 20. This can greatly reduce the overall volume of the protective fence 1, occupy less space, and is more conducive to the transportation and storage of the protective fence 1.

[0047] S3. During adjustment, first rotate the turntable 16 on the side of the support rod 2, so that the turntable 16 drives the secondary bevel gear 15 to rotate. The secondary bevel gear 15 drives the main bevel gear 14 to rotate synchronously under the meshing of the tooth threads. The main bevel gear 14 drives the screw 13 to rotate together. The movable cylinder 6 on the outside of the screw 13 moves upward under the drive of the screw 13 thread. During the upward movement, the reinforcing plate 18 drives multiple anti-climb rods 19 to pass through to the top of the slot 5, which can increase the overall height of the protective fence 1 and prevent pedestrians from climbing. The height of the protective fence 1 can be adjusted according to the engineering protection height and needs, thereby improving the convenience of using the protective fence 1.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
