[0029] like Figure 1-4 As shown, the utility model has the following specific embodiments.

[0030] Example:

[0031] A water level monitoring device, comprising a river bank, and further comprising:

[0032] A water level monitoring column 1, one end of the outer surface of the water level monitoring column 1 is connected with an arc-shaped protective plate 2 and a right-angle anti-impact plate 3, a filter screen port 11 is provided on the outer surface of the water level monitoring column 1, and a buoyancy box 4 is movably connected inside the water level monitoring column 1;

[0033] The mounting cover 6 is fixedly connected to the top of the water level monitoring column 1, a monitoring box 61 is fixedly connected to the top of the mounting cover 6, an infrared rangefinder 62 is fixedly connected inside the mounting cover 6, and the monitoring box 61 is electrically connected to the infrared rangefinder 62;

[0034] The mounting frame 5 is fixed on the river bank by means of bolts. Two groups of clamps 51 are provided on one side of the mounting frame 5 , and one end of the water level monitoring column 1 is clamped inside the clamp 51 .

[0035] By adopting the above technical solution, when using the device, the infrared rangefinder 62 can detect the distance from the reflective plate 41. The reflective plate 41 is fixed on the pontoon 4. The pontoon 4 can rise and fall inside the water level monitoring column 1. At the same time, the pontoon 4 always floats on the water surface, so that the distance detected by the infrared rangefinder 62 minus the height of the pontoon 4 is the depth of the water level. The water level monitoring column 1 can be fixed on the river bank through the mounting frame 5, and the arc-shaped protective plate 2 and the right-angle anti-impact plate 3 can protect the water level monitoring column 1, thereby improving the durability of the device and increasing the service life of the device.

[0036] Specifically, a reflective plate 41 is fixedly connected to the top of the buoyancy box 4 , and the reflective plate 41 is located directly below the infrared rangefinder 62 .

[0037] By adopting the above technical solution, the reflective plate 41 is located directly below the infrared rangefinder 62, which can reflect the infrared rays emitted by the infrared rangefinder 62, so that the infrared rangefinder 62 can quickly detect the distance from the reflective plate 41 and then detect the height of the water level.

[0038] Specifically, rollers 42 are fixedly connected to both sides of the buoyancy box 4 , and the inner wall of the water level monitoring column 1 is rollingly connected to the rollers 42 via the provided slide rails 12 .

[0039] By adopting the above technical solution, the buoyancy box 4 can roll inside the slide rail 12 through the fixed rollers 42 , so that the buoyancy box 4 can be easily raised and lowered inside the water level monitoring column 1 .

[0040] Specifically, there are two right-angle anti-impact plates 3 symmetrically arranged along the water flow direction, and the right-angle anti-impact plates 3 are fixed on the water level monitoring column 1 by setting screws.

[0041] By adopting the above-mentioned technical scheme, the right-angle anti-impact plate 3 is capable of changing the direction of turbulent impact. The right-angle anti-impact plate 3 adopts a right-angle structure design, which can make the impact forces on both sides offset each other, thereby reducing the impact force of the water flow on the water level monitoring column 1, and can better protect the water level monitoring column 1.

[0042] Specifically, the filter openings 11 are symmetrically arranged between two right-angled anti-impact plates 3 , the arc-shaped protective plate 2 is fixedly connected to the top of the filter opening 11 by a connecting rod 21 , and a gap is arranged between the arc-shaped protective plate 2 and the water level monitoring column 1 .

[0043] By adopting the above-mentioned technical scheme, the arc-shaped protective plate 2 fixedly connected to the outer surface of the water level monitoring column 1 is arranged directly in front of the filter opening 11 on the outer surface of the water level monitoring column 1, so as to protect the filter opening 11 and prevent the solids in the water from following the turbulence and causing impact damage. At the same time, the gap between the arc-shaped protective plate 2 and the filter opening 11 can facilitate the entry of water.

[0044] Specifically, the monitoring box 61 also includes a controller, a signal transceiver, and a battery pack, and the mounting cover (6) is threadedly matched with the water level monitoring column (1).

[0045] By adopting the above-mentioned technical scheme, the battery pack arranged in the monitoring box 61 can power the signal transceiver, the controller and the infrared rangefinder 62, the arranged controller can control the infrared rangefinder 62 to run the detection, and the arranged signal transceiver can transmit the monitoring signal to the remote terminal, so as to remotely receive the data detected by the infrared rangefinder 62, wherein the mounting cover 6 and the water level monitoring column 1 are threadedly matched, so as to facilitate the disassembly and assembly of the infrared rangefinder 62 on the mounting cover 6, and facilitate inspection and maintenance.
