[0022] Example 1

[0023] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A safety fence for water conservancy and hydropower construction includes a first mounting pipe 1. Several connecting rods 2 are fixedly installed on one side of the first mounting pipe 1. A second mounting pipe 3 is fixedly installed on one side of the connecting rods 2. A connecting block 5 is fixedly installed on one side of the first mounting pipe 1. Two limiting plates 4 are fixedly installed on one side of the second mounting pipe 3. An adjustment assembly is provided inside the first mounting pipe 1 and the second mounting pipe 3 for adjusting the height of the first mounting pipe 1, connecting rods 2, and second mounting pipe 3. The adjustment assembly includes two adjusting columns 6, which are respectively movably fitted inside the first mounting pipe 1 and the second mounting pipe 3. Positioning pipes 8 are respectively provided on one side of the first mounting pipe 1 and the second mounting pipe 3. Positioning holes 10 are provided on one side of the tube 3. The inner circular wall of the positioning hole 10 is fixedly sleeved with the positioning tube 8. A base plate 11 is fixedly installed on the bottom surface of the adjusting column 6. Several limiting grooves 9 are provided on one side of the adjusting column 6. A first pressure plate 13 is movably sleeved on the inner circular wall of the positioning tube 8. A first limiting post 14 is fixedly installed on one end of the first pressure plate 13. The first limiting post 14 is movably sleeved with the inner circular wall of the limiting groove 9. A connecting post 15 is fixedly installed on the other end of the first pressure plate 13. A first spring 16 is movably sleeved on the outer circular wall of the connecting post 15. A fixing ring 17 is fixedly sleeved on the inner circular wall of the positioning tube 8. The inner circular wall of the fixing ring 17 is movably sleeved with the connecting post 15. An adjusting block 18 is provided at one end of the positioning tube 8. One end of the adjusting block 18 is connected to the connecting post 15. The connecting column 15 is fixedly installed. The top and bottom surfaces of the connecting block 5 are respectively provided with mounting grooves 23. A second spring 24 is fixedly installed on the bottom surface of the mounting groove 23. A second pressure plate 25 is movably sleeved on the inner circular wall of the mounting groove 23. The bottom surface of the second pressure plate 25 is fixedly installed with the second spring 24. A second limiting post 26 is fixedly installed on the top surface of the second pressure plate 25. A limiting hole 7 is provided on the top surface of the limiting plate 4. The inner circular wall of the limiting hole 7 is movably sleeved with the second limiting post 26. Through the provided adjusting post 6, during use, the worker assembles the fence formed by multiple first mounting pipes 1, connecting rods 2, and second mounting pipes 3 according to the required enclosure length. During assembly, the worker inserts the connecting block 5 between the two limiting plates 4. During this process, the worker will... Two second limiting posts 26 are pressed into the mounting groove 23. The downward movement of the second limiting posts 26 causes the second pressure plate 25 to compress the second spring 24. When the connecting block 5 is inserted between the two limiting plates 4, the rebound force of the second spring 24 pushes the second pressure plate 25 and the second limiting posts 26 upward. Then, the two second limiting posts 26 are inserted into the limiting hole 7, thereby assembling the fence formed by multiple first mounting tubes 1, connecting rods 2, and second mounting tubes 3. When the operator needs to adjust the height of the fence formed by the first mounting tubes 1, connecting rods 2, and second mounting tubes 3, the operator pulls the adjusting block 18. The movement of the adjusting block 18 causes the connecting post 15, the first pressure plate 13, and the first limiting post 14 to move.Then, the first pressure plate 13 compresses the first spring 16, and the first limiting post 14 retracts into the positioning tube 8. At this time, the first mounting tube 1 and the second mounting tube 3, which were limited by the two first limiting posts 14, are released from their limits. The operator can then lift the fence composed of the first mounting tube 1, connecting rod 2, and second mounting tube 3 upwards. The fence will then move along the direction of the two adjusting posts 6. Once the fence is adjusted to a suitable height, the operator releases the adjusting block 18. The rebound force of the first spring 16 will then push the first pressure plate 13 and the first limiting post 14 to move. The first limiting post 14 will then insert into the adjacent limiting groove 9. At this point, the two first limiting posts 14 can limit and fix the first mounting tube 1 and the second mounting tube 3 after height adjustment, thus achieving the effect of adjusting the usable height of the fence composed of the first mounting tube 1, connecting rod 2, and second mounting tube 3.

[0024] Example 2

[0025] Based on the above embodiment 1, refer to Figure 3 and Figure 4 A first limiting ring 22 is fixedly sleeved on the inner circular wall of the positioning tube 8. The inner circular wall of the first limiting ring 22 is movably sleeved with the first limiting post 14. The first limiting ring 22 prevents misalignment between the first pressure plate 13 and the positioning tube 8. A slot 21 is provided on the outer circular wall of the positioning tube 8. A locking block 20 is fixedly installed on the outer circular wall of the first pressure plate 13. The locking block 20 is movably sleeved with the inner wall of the slot 21. Through the slot 21 and the locking block 20, when the first pressure plate 13 moves, the locking block 20 will move inside the slot 21. The first limiting post 14 retracts into the positioning tube 8, and the operator rotates the adjusting block 18. The rotation of the adjusting block 18 will drive the connecting post 15 and the first pressure plate 13 to rotate. At this time, the locking block 20 will be locked into the slot 21, and the operator can then release the adjusting block 18 and adjust the height of the fence. The outer circular wall of the adjusting block 18 is fixedly fitted with an anti-slip sleeve 19 to prevent the operator from slipping when using the adjusting block 18.

[0026] Example 3

[0027] Based on the above embodiment 1 or 2, refer to Figure 3 and Figure 5A second limiting ring 27 is fixedly sleeved on the inner circular wall of the mounting groove 23. The inner circular wall of the second limiting ring 27 is movably sleeved with the second limiting post 26. The second limiting ring 27 prevents misalignment between the second pressure plate 25 and the mounting groove 23. Two sliding holes 29 are opened on one side of the connecting block 5, and the sliding holes 29 are connected to the mounting groove 23. An adjusting rod 28 is fixedly installed on the outer circular wall of the second pressure plate 25. The adjusting rod 28 is movably sleeved with the inner wall of the sliding hole 29. The adjusting rod 28 allows the second pressure plate 25 to adjust its position when the second pressure plate 25 is in the mounting groove 23. When assembling the fence, the worker presses the adjusting rod 28, which in turn moves the second pressure plate 25 and the second limiting post 26, making it easier for the worker to assemble multiple fences. A fixing cone 12 is fixedly installed on the bottom surface of the base plate 11. When the worker places the first mounting tube 1 and the second mounting tube 3, the worker inserts the fixing cone 12 into the bottom surface, thereby improving the stability of the first mounting tube 1 and the second mounting tube 3 during placement.

[0028] Working principle: Please refer to Figures 1-5As shown, through the adjustable column 6, during use, the worker assembles the fence formed by multiple first mounting pipes 1, connecting rods 2, and second mounting pipes 3 according to the required enclosure length. During assembly, the worker inserts the connecting block 5 between the two limiting plates 4. During this process, the worker presses the two second limiting columns 26 into the mounting groove 23. The downward movement of the second limiting columns 26 causes the second pressure plate 25 to compress the second spring 24. When the connecting block 5 is inserted between the two limiting plates 4, the rebound force of the second spring 24 pushes the second pressure plate 25 and the second limiting column 26 upward. Then, the two second limiting columns 26 are inserted into the limiting hole 7, thus assembling the fence formed by multiple first mounting pipes 1, connecting rods 2, and second mounting pipes 3. When the worker needs to adjust the height of the fence formed by the first mounting pipes 1, connecting rods 2, and second mounting pipes 3, the worker pulls the adjusting block 18. The movement of the adjusting block 18 causes the connecting column 15, the first pressure plate 13, and the first limiting column 14 to move. Then, the first pressure plate 13 presses against the first spring 16, and the first limiting post 14 retracts into the positioning tube 8. At this time, the first mounting tube 1 and the second mounting tube 3, which were limited by the two first limiting posts 14, are released from their positions. The operator can then lift the fence composed of the first mounting tube 1, connecting rod 2, and second mounting tube 3 upwards. The fence will then move along the direction of the two adjusting posts 6. Once the fence is adjusted to a suitable height, the operator releases the adjusting block 18. The rebound force of the first spring 16 will then push the first pressure plate 13 and the first limiting post 14 to move. The first limiting post 14 will then insert into the adjacent limiting groove 9. At this point, the two first limiting posts 14 can limit and fix the first mounting tube 1 and the second mounting tube 3 after height adjustment, thus achieving the effect of adjusting the usable height of the fence composed of the first mounting tube 1, connecting rod 2, and second mounting tube 3.
