[0002] Water conservancy and hydropower projects involve the use of water resources to generate electricity or for irrigation, water supply and other purposes. Warning signs used in water conservancy and hydropower projects are usually used for identification, warning and guidance to ensure the safe operation of the project and the safety of personnel;

[0003] According to application number: 202220551405.4, a construction warning sign for water conservancy and hydropower engineering construction is disclosed, comprising: a supporting plate, a warning sign is installed on the top of the supporting plate, and fill-in lights are embedded on both sides of the warning sign, a loudspeaker is installed on the top of the warning sign, and a solar panel assembly is installed on the back of the warning sign; a bearing rod is installed at the bottom end of the supporting plate, a bearing sleeve is installed at the bottom end of the bearing rod, and a water pipe and a wire are installed inside the bearing rod. The warning sign set in this comparative case can mark the warning slogan, so as to warn others, and at the same time, the fill-in light can be set to conveniently provide light for the warning sign when it is dark, so as to facilitate warning.

[0023] Example 1

[0024] like Figure 1-4 As shown, this is the first embodiment of the utility model, which provides an adjustable warning sign for water conservancy and hydropower engineering construction, including a base plate 1, a fixing box 2 is fixedly connected to the center of the top of the base plate 1, the top of the fixing box 2 is fixedly connected to the limiting column 3, the inner cavity of the limiting column 3 is slidably connected to the lifting column 4, the top of the lifting column 4 extends to the outside of the limiting column 3 and is fixedly connected to the fixing plate 5, the inner cavity of the base plate 1 is provided with an adjustment mechanism 6, the top of the fixing plate 5 is fixedly connected to the hollow plate 7, the top of the hollow plate 7 is provided with a top plate 8, the bottom of the top plate 8 is fixedly connected to a transparent placement rack 9, the bottom of the transparent placement rack 9 extends to the inner cavity of the hollow plate 7, and is detachably connected to the inner cavity of the hollow plate 7;

[0025] The adjustment mechanism 6 includes a hollow column 601, which is located on both sides of the top of the base plate 1 and is fixedly connected to the inner cavity of the base plate 1. The hollow column 601 is communicated with the fixed box 2. A through groove 602 is provided on the top of the hollow column 601. The inner cavity of the through groove 602 is slidably connected to an adjustment plate 603. The top of the adjustment plate 603 is movably connected to the bottom of the fixed plate 5 through a rotating shaft.

[0026] like Figure 1-4 As shown, the bottom plate 1 is used to support the entire device and improve the stability of the device when in use. The limit column 3 and the lifting column 4 are used to support the fixed plate 5. The adjustment mechanism 6 can be used to adjust the height of the fixed plate 5. The height of the fixed plate 5 is automatically adjusted by the machine, which is not only convenient to operate, but also saves manpower and improves the efficiency of adjusting the height of the fixed plate 5. The fixed plate 5 is used to support the hollow plate 7. The hollow plate 7 is used to accommodate a transparent placement rack 9. The transparent placement rack 9 is used to place warning words. By removing the top plate 8, the transparent placement rack 9 can be taken out from the inside of the hollow plate 7, so that the warning words can be replaced, making the device suitable for different application scenarios.

[0027] Example 2

[0028] Reference Figure 1 and 3 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0029] In this embodiment, the inner cavity of the fixed box 2 is fixedly connected to a dual-axis motor 604, and the output shafts on both sides of the dual-axis motor 604 are transmission-connected to threaded rods 605. The threads on the surfaces of the two threaded rods 605 are set in opposite directions, and the end of the threaded rod 605 away from the hollow column 601 is movably connected to the inner wall of the hollow column 601 through a bearing.

[0030] The surface of the threaded rod 605 is threadedly connected with a threaded sleeve 606 , and the bottom of the adjustment plate 603 and the top of the threaded sleeve 606 are movably connected via a rotating shaft.

[0031] like Figure 1 and 3 As shown, the dual-axis motor 604 is used to drive the two threaded rods 605 to rotate. Since the threads on the surfaces of the two threaded rods 605 are set in opposite directions, the two threaded rods 605 can be driven to move synchronously and in opposite directions on the surfaces of the threaded rods 605. When the threaded sleeve 606 moves, the angle of the adjustment plate 603 can be adjusted. Since the adjustment plate 603 supports the fixed plate 5, when the angle of the adjustment plate 603 changes, the height of the fixed plate 5 will also rise and fall accordingly, thereby achieving the purpose of adjusting the height of the fixed plate 5.

[0032] Example 3

[0033] Reference Figure 2 and4 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0034] In this embodiment, a transparent plate 10 is fixedly connected to the center of the front surface of the hollow plate 7 , and reflective stickers 11 are fixedly connected to both sides of the front surface of the hollow plate 7 .

[0035] Magnets 12 are fixedly connected to both sides of the top of the hollow plate 7 and both sides of the bottom of the top plate 8. The two magnets 12 have opposite magnetic properties and are magnetically connected.

[0036] Limiting grooves 13 are provided on both sides of the inner cavity of the limiting column 3, and limiting blocks 14 are fixedly connected to both sides of the lifting column 4. One side of the limiting block 14 extends to the inner cavity of the limiting groove 13 and is slidably connected to the inner cavity of the limiting groove 13.

[0037] like Figure 2 and 4 As shown, the transparent plate 10 serves to facilitate the display of the warning content, the reflective sticker 11 can reflect light when exposed to light, thereby noticing the existence of the device in passing vehicles, the magnet 12 is used to position the top plate 8 to improve the stability of the top plate 8 on the top of the hollow plate 7, and the limiting groove 13 and the limiting block 14 cooperate to limit the lifting column 4 to prevent it from sliding out from the inside of the limiting column 3.

[0038] When in use, first place the warning word inside the transparent placement rack 9, then move the top plate 8, and insert the transparent placement rack 9 into the inner cavity of the hollow plate 7. At this time, the magnet 12 can position the top plate 8. When the height of the fixed plate 5 needs to be adjusted, start the dual-axis motor 604. The dual-axis motor 604 is used to drive the two threaded rods 605 to rotate. Since the threads on the surfaces of the two threaded rods 605 are set in opposite directions, the two threaded rods 605 can be driven to move synchronously and in opposite directions on the surfaces of the threaded rods 605. When the threaded sleeve 606 moves, it can adjust the angle of the adjustment plate 603. Since the adjustment plate 603 supports the fixed plate 5, when the angle of the adjustment plate 603 changes, the height of the fixed plate 5 will also rise and fall accordingly, thereby achieving the purpose of adjusting the height of the fixed plate 5.

The control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.
