[0028] See also Figure 1-6 , the utility model provides a technical solution: a water conservancy project safety monitoring data automatic collection and early warning device, comprising a vertical pole 1, and a protective cover 5 is arranged on the vertical pole 1 through a lifting mechanism;

[0029] The lifting mechanism includes a fixed plate 2, two fixed plates 2 are fixed on one side of the vertical pole 1, and a rotating shaft 3 is rotatably installed between the fixed plates 2 through a bearing. A movable plate 4 is arranged on the outer side of the vertical pole 1 and the rotating shaft 3, and a protective cover 5 is fixed on the end of the movable plate 4. A docking groove 7 is opened on the top of the protective cover 5, and a docking column 8 is installed inside the docking groove 7. The lower end of the docking column 8 passes through the docking groove 7 and a laser ranging sensor 9 is fixed inside. The top of the laser ranging sensor 9 fits with the top of the protective cover 5. A handle 6 is fixed on the lower end of the rotating shaft 3. The rotating shaft 3 and the movable plate 4 are threadedly connected. The movable plate 4 and the vertical pole 1 are slidably connected. The docking groove 7 and the docking column 8 are threadedly connected. The diameter of the bottom of the protective cover 5 is larger than the diameter of the top of the protective cover 5, which is convenient for disassembly and installation of the laser ranging sensor 9. By rotating the handle 6 forward or reversely, the protective cover 5 and the laser ranging sensor 9 inside the protective cover 5 can be moved upward or downward, so that the height of the laser ranging sensor 9 can be reduced, which is convenient for disassembly and maintenance of the laser ranging sensor 9.

[0030] A floating plate 10 is arranged below the protective cover 5. The floating plate 10 is connected to the upright pole 1 through a sliding mechanism. The sliding mechanism includes a groove 11. The end of the floating plate 10 is provided with a groove 11. Three-fifths of the outer side of the upright pole 1 is located inside the groove 11. A slider 12 is fixed to the inner wall of the groove 11. The end of the slider 12 is located inside the slide groove 13. The slide groove 13 is arranged on the outer side of the upright pole 1. The floating plate 10 is slidably connected to the upright pole 1 through the groove 11. The slider 12 is slidably connected to the upright pole 1 through the slide groove 13. Both the slider 12 and the slide groove 13 are symmetrically distributed about the central axis of the upright pole 1, so that the floating plate 10 can move up and down without rotation, so that the laser irradiated downward by the laser ranging sensor 9 can always shine on the top of the floating plate 10, which is beneficial to the laser ranging sensor 9 to measure the distance of the water surface, and ensures that the floating plate 10 will not touch the movable plate 4 when moving up and down, so that the handle 6 under the movable plate 4 can be installed at a lower position, which is convenient for the person sitting on the boat to rotate the handle 6 and reduce the height of the laser ranging sensor 9.

[0031] A supporting mechanism is provided at the bottom of one side of the vertical pole 1, and the supporting mechanism includes a baffle 14. The baffle 14 is fixed on the outer wall of the vertical pole 1, and a fixing rod 15 is fixed between the baffles 14. A supporting rod 16 is rotatably installed on the outer side of the fixing rod 15, and a fixing bolt 18 penetrates the bottom of the support rod 16. A supporting block 17 is fixed to the bottom of one side of the vertical pole 1, and four supporting rods 16 are distributed at equal angles with respect to the central axis of the vertical pole 1. The support rod 16 is tilted in design, and four supporting blocks 17 are distributed at equal angles with respect to the central axis of the vertical pole 1, and the supporting block 17 is tilted in design, which increases the floor space of the bottom of the water level collection and early warning device, so that the bottom of the water level collection and early warning device can be stably fixed on the bottom of the water, thereby reducing the probability of the water level collection and early warning device tipping over.

[0032] Working principle: When using the automatic data collection and early warning device for water conservancy project safety monitoring, first insert the bottom of the vertical pole 1 into the underwater soil, then rotate the support rod 16 to make the support rod 16 tilt, and then insert the lower end of the fixing bolt 18 through the bottom of the support rod 16 into the underwater soil. According to the above operation, the other three support rods 16 are fixed. With the support of the four support rods 16, the vertical pole 1 can be stably installed in the water. At the same time, the support block 17 at the bottom of one side of the vertical pole 1 is also inserted into the soil, which further increases the stability of the vertical pole 1 installed in the water.

[0033] When the water surface rises and falls, the floating plate 10 can also move up and down under the action of buoyancy. The floating plate 10 can also drive the slider 12 to move up and down inside the slide 13. The laser distance sensor 9 inside the protective cover 5 (the model of the laser distance sensor 9 is: HAD-DLS-B15, which has its own Bluetooth) emits a laser to illuminate the floating plate 10, and then reflects it to the laser distance sensor 9, so that the laser distance sensor 9 can measure the height of the water surface, and then the data measured by the laser distance sensor 9 is transmitted to the computer in the control room through its internal Bluetooth wireless. The computer can analyze the data and monitor and warn the water level.

[0034] When the laser ranging sensor 9 needs to be repaired, the maintenance personnel move to the side of the vertical pole 1 by boat, and then rotate the handle 6. At this time, the handle 6 drives the rotating shaft 3 to rotate. Since the rotating shaft 3 and the movable plate 4 are threadedly connected, and the movable plate 4 and the vertical pole 1 are slidingly connected, the movable plate 4, the protective cover 5 and the laser ranging sensor 9 move downward at the same time until the laser ranging sensor 9 is lowered to a suitable position. Then the laser ranging sensor 9 is rotated to rotate the docking column 8. Since the docking column 8 and the docking groove 7 are threadedly connected, it is convenient to disassemble the laser ranging sensor 9 for maintenance.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
