The bottom of the column 1 is rotatably connected to the base 2, and a column 15 is arranged at the top of the column 1. Two connecting rods 3 rotatably connected to the column 1 are arranged on the column 1, and the two connecting rods 3 are parallel, and the two connecting rods 3 are both rotatably connected to the guide rod 4. A pressure detection plate 8 is arranged on the guide rod 4, and the pressure detection plate 8 is located below the floating platform 9. The pressure detection plate 8 is electrically connected to the controller. A movable plate 7 is slidably arranged on the guide rod 4, and the movable plate 7 is located below the pressure detection plate 8 and abuts against its lower surface. A plug 6 is arranged at the bottom of the guide rod 4. The driving assembly is rotatably connected to the column 1 and one of the connecting rods 3. The floating platform 9 is slidably connected to the guide rod 4. The mounting plate 11 connects the guide rod 4 and the laser detection probe 12, and the detection end of the laser detection probe 12 faces the upper surface of the floating platform 9. The cross bar 19 is connected to the circular ring 18, and the circular ring 18 is sleeved on the column 15 and rotatably connected thereto. A limiter A is provided in the cross bar 19 for limiting the relative rotation of the circular ring 18 and the column 15. The limiter A includes a slider B25. The slider B25 is slidably connected to the cross bar 19, and a plug rod B26 is provided on the cross bar 19. A plurality of limit grooves A151 are provided in a ring array on the column 15, and the plug rod B26 is inserted into the corresponding limit groove A151 and slidably connected thereto. A tensioning assembly B27 is provided on the cross bar 19 for pushing the slider B25 to keep the plug rod B26 in the limit groove A151. The photovoltaic panel assembly 20 is movably connected to the cross bar 19, and a limiter B is provided in the cross bar 19 for limiting the rotation of the photovoltaic panel assembly 20 and the cross bar 19 in the vertical direction. The limiter B includes a slider A22. The slider A22 is slidably connected to the cross bar 19, and a plug rod A23 is provided on the slider A22. The photovoltaic panel assembly 20 is provided with an adapter, and a rotating shaft 21 is provided on the adapter. A plurality of limit grooves B211 are provided on the rotating shaft 21 in a circular array. The insertion rod A23 is inserted into the corresponding side limit groove B211 and slidably connected thereto, and a tensioning assembly A24 for pushing the slider A22 to keep the insertion rod A23 in the limit groove B211 is provided on the cross bar 19. It also includes a plurality of conductive slip rings 16. The photovoltaic panel assembly 20 is electrically connected to the energy storage assembly through a plurality of conductive slip rings 16, a circular ring 18 and a cross bar 19. The energy storage assembly and the controller are electrically connected to the laser detection probe 12 through a plurality of conductive slip rings 16 and a connecting rod 3. The control box 28 is provided with an energy storage assembly and a controller. The photovoltaic panel assembly 20 is electrically connected to the energy storage assembly. The energy storage assembly is electrically connected to the hydraulic cylinder 5, the controller and the laser detection probe 12. The control box 28 is also provided with a timer switch for timing the hydraulic cylinder 5.

[0030] In this embodiment, the base 2 is fixed on the river bank, the column 1 is rotated to make the guide rod 4 face the water surface, and then the hydraulic cylinder 5 is started. The hydraulic cylinder 5 drives the connecting rod 3 to rotate and press the guide rod 4 into the water. After the guide rod 4 is placed in the water, the movable plate 7 at the bottom of the guide rod 4 preferentially contacts the riverbed, and the movable plate 7 generates an upward thrust on the pressure detection plate 8. When the pressure detection plate 8 detects a large thrust, the signal is fed back to the controller, and the controller controls the hydraulic cylinder 5 to stop the action. This structure is used to determine whether the guide rod 4 is in place, so that the water level height measurement result is based on the accurate height from the riverbed surface to the water surface. Due to the accumulation of silt on the riverbed, the riverbed height will gradually rise. The water level depth data obtained at this time is not accurate, so it needs to be recalibrated. When the timer reaches the preset time interval, the hydraulic cylinder 5 drives the connecting rod 3 to rotate and lift the guide rod 4 from the water, and then lowers the guide rod 4 again until the movable plate 7 falls on the raised riverbed. Since the utility model is installed outdoors and it is difficult to supply city electricity, photovoltaic power generation is adopted. During the actual installation, it is necessary to adjust the angle and direction of the photovoltaic panel assembly 12. At this time, the flipping angle of the photovoltaic panel is adjusted first. The staff slides the slider A22 and pulls the plug A23 out of the limit groove B211. At this time, the flipping adjustment of the photovoltaic panel assembly 12 is not restricted. After adjusting the flipping angle of the photovoltaic panel assembly 12, the slider A22 is released. The plug A23 is automatically inserted into the corresponding limit groove B211 under the tension of the tensioning component A and forms a limit on the flipping angle of the photovoltaic panel assembly 12. Then, the horizontal direction of the photovoltaic panel assembly 12 is adjusted. The staff slides the slider B25 and drives the plug B26 to be pulled out of the limit groove A151. After rotating the cross bar 19 until the photovoltaic panel assembly 12 faces the best light-facing angle, the slider B25 is released. The slider B25 re-inserts the plug B26 into the corresponding limit groove A151 under the tension of the tensioning component B27. It should be noted that, in the present embodiment, the laser detection probe 12 can also be replaced by an ultrasonic ranging probe, and the measurement results are displayed on the display screen of the control box 28 for easy viewing by the staff.

The mounting plate 11 and the floating platform 9 are connected by a multi-section telescopic tube 13. The laser detection probe 12 and the reflector 10 are both located on the inner side of the multi-section telescopic tube 13, and an exhaust pipe 14 connected to the interior of the multi-section telescopic tube 13 is arranged on the multi-section telescopic tube 13.

[0033] In this embodiment, a multi-section telescopic tube 13 is used to protect the reflector 10 and the laser detection probe 12 to prevent dust from having an adverse effect on the laser detection probe 12, and to prevent sand and gravel and other debris on the floating platform from affecting the accuracy of the ranging of the laser detection probe 12. The multi-section telescopic tube 13 needs to keep the internal air pressure consistent with the external pressure when extending and retracting, so it can be achieved through the exhaust pipe 14 to prevent the rise and fall of the floating platform 9 from being affected by the air pressure resistance in the tube.

[0034] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
