During the construction of water conservancy projects, fences are generally installed at the construction site to ensure the normal progress of water conservancy construction.

[0003] The existing fence height is relatively fixed and cannot be adjusted. Different construction sites may require fences of different heights to meet safety and management needs. Fences that cannot be adjusted in height have poor applicability and cannot meet the safety requirements of specific sites. Utility Model Content

[0004] The purpose of this utility model is to provide a fence for water conservancy engineering construction, so as to solve the problem mentioned in the background art that the existing fences have a relatively fixed height and cannot be adjusted, resulting in poor applicability of the fences and failure to meet the safety requirements of specific sites.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fence for water conservancy engineering construction, comprising a base, a vertical pole fixedly connected to the surface of the base, a horizontal bar fixedly connected to the surface of the vertical pole, an adjustment mechanism provided on the surface of the base, the adjustment mechanism comprising a guide rod, the guide rod fixedly connected to the surface of the base, a first movable rod slidably connected to the surface of the guide rod, a first connecting rod fixedly connected to the bottom of the first movable rod, a second connecting rod fixedly connected to the top of the first movable rod, second movable rods fixedly connected to both ends of the second connecting rod, a fixing nut fixedly connected to both ends of the first connecting rod, a limit bolt threadedly connected to the surface of the fixing nut, and a limit groove formed on the surface of the vertical pole.

[0006] Preferably, a warning mechanism is provided on the surface of the crossbar. The warning mechanism includes a fixing frame, which is fixedly connected to the surface of the crossbar. A double-ended screw is rotatably connected to the surface of the fixing frame. A square nut is threaded onto the surface of the double-ended screw. A knob is fixedly connected to the surface of the double-ended screw. An installation rod is fixedly connected to the bottom of the square nut. A warning sign is engaged with the surface of the installation rod.

[0007] Preferably, multiple sets of guide rods and first movable rods are provided and arranged linearly. A guide groove is provided at the bottom of the first movable rod, and the first movable rod slides on the surface of the guide rod through the guide groove. Multiple sets of guide holes are provided on the surface of the crossbar, and the first movable rod slides on the multiple sets of guide holes of the crossbar. A reinforcing rib is provided at the bottom of the guide rod.

[0008] Preferably, the length of the second connecting rod is greater than the length of the crossbar, and a guide groove is formed on the surface of the crossbar. The second movable rod slides on the guide groove of the crossbar, and the second movable rod slides synchronously with the first movable rod through the second connecting rod.

[0009] Preferably, the limiting grooves are provided in multiple sets and are arranged linearly and evenly on the surface of the upright. The limiting bolts are inserted into the limiting grooves by fixing nuts, and the upright restricts the position of the first connecting rod by fixing nuts and limiting bolts.

[0010] Preferably, the bottom of the fixing frame is provided with a guide groove, the bidirectional screw rotates on the guide groove of the fixing frame, and the bidirectional screw drives the square nut to slide on the guide groove of the fixing frame by rotation.

[0011] Preferably, there are two sets of square nuts, and the sliding directions of the two sets of square nuts are opposite. The square nuts drive the mounting rod to slide synchronously. A slot is opened on the surface of the mounting rod, and the warning sign is engaged and connected to the slot of the mounting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This fence features a first movable rod that slides on the guide rod and the surface of the crossbar. The first movable rod, via a second connecting rod, drives a second movable rod to slide on the guide groove of the upright. By adjusting the height of the first movable rod, the second connecting rod, and the second movable rod, the overall height of the fence is changed. A limiting bolt is rotated on the surface of the fixing nut, causing the limiting bolt to engage with a set of limiting grooves on the upright. The upright, through the fixing nut, the limiting bolt, and the limiting grooves, restricts the horizontal height of the first connecting rod on the upright. The first connecting rod, in turn, restricts the horizontal height of the first movable rod, the second connecting rod, and the second movable rod, ensuring the adjusted height of the fence. This allows for appropriate height adjustment, improving the fence's adaptability and meeting the needs of specific situations.

[0014] 2. This fence, by rotating a knob on the surface of the fixing frame, drives a double-ended screw to rotate on the fixing frame. The double-ended screw drives two sets of square nuts to slide on the guide groove of the fixing frame. The two sets of square nuts drive the mounting rod to move towards the center. The slot of the mounting rod restricts the warning sign between the two sets of mounting rods, thus completing the installation of the warning sign on the mounting rod. It also facilitates the disassembly and replacement of the warning sign, greatly improving the flexibility of the warning mechanism and making it easy to adjust the warning sign on the fence.

[0023] Please see Figure 1-6 One embodiment provided by this utility model:

[0024] A fence for water conservancy construction includes a base 1, with uprights 11 fixedly connected to the surface of the base 1, and horizontal bars 12 fixedly connected to the surface of the uprights 11. An adjustment mechanism is provided on the surface of the base 1, comprising a guide rod 2 fixedly connected to the surface of the base 1, a first movable rod 21 slidably connected to the surface of the guide rod 2, a first connecting rod 22 fixedly connected to the bottom of the first movable rod 21, a second connecting rod 26 fixedly connected to the top of the first movable rod 21, second movable rods 27 fixedly connected to both ends of the second connecting rod 26, and fixing nuts 23 fixedly connected to both ends of the first connecting rod 22. Limit bolts 24 are threadedly connected to the surface of the fixing nuts 23, and limit grooves 25 are formed on the surface of the uprights 11. This adjustment mechanism can change the horizontal height of the first movable rod 21, the second connecting rod 26, and the second movable rod 27, thereby adjusting the actual usable height of the entire fence, improving the adaptability of the fence, and meeting the needs of the fence in specific situations.

[0025] Furthermore, a warning mechanism is provided on the surface of the crossbar 12. The warning mechanism includes a fixing frame 3, which is fixedly connected to the surface of the crossbar 12. A double-acting screw 31 is rotatably connected to the surface of the fixing frame 3. A square nut 33 is threadedly connected to the surface of the double-acting screw 31. A knob 32 is fixedly connected to the surface of the double-acting screw 31. An installation rod 34 is fixedly connected to the bottom of the square nut 33. A warning sign 35 is engaged with the surface of the installation rod 34. The warning sign 35 on this warning mechanism can be installed and removed for easy replacement, which greatly improves the flexibility of the warning mechanism and facilitates the adjustment of the warning sign 35 on the fence.

[0026] Furthermore, multiple sets of guide rods 2 and first movable rods 21 are provided and arranged linearly. The bottom of the first movable rod 21 is provided with a guide groove, and the first movable rod 21 slides on the surface of the guide rod 2 through the guide groove. Multiple sets of guide holes are provided on the surface of the crossbar 12, and the first movable rod 21 slides on the multiple sets of guide holes of the crossbar 12, thereby ensuring the stability of the first movable rod 21 after sliding. Sliding the first movable rod 21 can change the overall height of the entire fence, thereby realizing the adjustment of the fence height. The bottom of the guide rod 2 is provided with reinforcing ribs to ensure the stability of multiple sets of guide rods 2.

[0027] Furthermore, the length of the second connecting rod 26 is greater than the length of the crossbar 12. A guide groove is provided on the surface of the crossbar 12. The second movable rod 27 slides on the guide groove of the crossbar 12. The second movable rod 27 slides synchronously with the first movable rod 21 through the second connecting rod 26. The second movable rod 27 can adjust the height of the upright 11, ensuring the adjustment of the overall height of the fence and avoiding deviation in the height of the upright 11 of the fence after adjustment.

[0028] Furthermore, multiple sets of limiting grooves 25 are provided and are arranged linearly and evenly on the surface of the upright 11. The limiting bolts 24 are inserted into the limiting grooves 25 through the fixing nuts 23. The upright 11 restricts the position of the first connecting rod 22 through the fixing nuts 23 and the limiting bolts 24, ensuring the horizontal height of the first connecting rod 22 on the upright 11. The first connecting rod 22, in turn, restricts the height of the first movable rod 21, the second connecting rod 26 and the second movable rod 27, thereby ensuring the height of the fence after adjustment.

[0029] Furthermore, a guide groove is provided at the bottom of the fixing frame 3. The bidirectional screw 31 rotates on the guide groove of the fixing frame 3. The bidirectional screw 31 drives the square nut 33 to slide on the guide groove of the fixing frame 3 by rotation. The bidirectional screw 31 is driven to rotate by the knob 32. The square nut 33 drives the mounting rod 34 to move during the sliding process.

[0030] Furthermore, two sets of square nuts 33 are provided, and the sliding directions of the two sets of square nuts 33 are opposite. The square nuts 33 drive the mounting rods 34 to slide synchronously. The mounting rods 34 have slots on their surfaces, and the warning sign 35 is engaged with the slots on the mounting rods 34. The slots of the two sets of mounting rods 34 restrict the position of the warning sign 35 on the mounting rods 34, thereby restricting the position of the warning sign 35 on the fence, making it convenient to install and remove the warning sign 35 on the fence.

[0031] Working principle: The first movable rod 21 slides on the surface of the guide rod 2 and the surface of the crossbar 12. The first movable rod 21 drives the second movable rod 27 to slide on the guide groove of the upright 11 through the second connecting rod 26. By adjusting the height of the first movable rod 21, the second connecting rod 26 and the second movable rod 27, the height of the entire fence is changed. The limiting bolt 24 is rotated on the surface of the fixing nut 23, so that the limiting bolt 24 is inserted into a set of limiting grooves 25 on the upright 11. The upright 11 limits the horizontal height of the first connecting rod 22 on the upright 11 through the fixing nut 23, the limiting bolt 24 and the limiting grooves 25. The first connecting rod 22 limits the horizontal height of the first movable rod 21, the second connecting rod 26 and the second movable rod 27, ensuring the height of the fence after adjustment. This allows the height of the fence to be adjusted appropriately, improving the adaptability of the fence and meeting the needs of the fence in specific occasions.

[0032] Rotating the knob 32 on the surface of the fixing frame 3 drives the bidirectional screw 31 to rotate on the fixing frame 3. The bidirectional screw 31 drives two sets of square nuts 33 to slide on the guide groove of the fixing frame 3 through rotation. The two sets of square nuts 33 drive the mounting rod 34 to move towards the center. The slot of the mounting rod 34 restricts the warning sign 35 between the two sets of mounting rods 34, thereby completing the installation of the warning sign 35 on the mounting rod 34. It also facilitates the disassembly and replacement of the warning sign 35, greatly improving the flexibility of the warning mechanism and making it easy to adjust the warning sign 35 on the fence.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
