[0047] An auxiliary detection assembly 4 is installed on the top surface of the pontoon 1. The auxiliary detection assembly 4 includes a telescopic rod 401, a reinforcement ring 402, a floating ring 403, a top rod 404, a top plate 405, an inclined support plate 406, a buffer strip 407, a hollow floating plate 408, a solar panel 409, a waterproof box 410, a battery 411 and an equipment plate 412;

[0048] The top surface of the pontoon 1 is evenly welded with telescopic rods 401, and several telescopic rods 401 are fixed through the top corner of the reinforcement ring 402. The top ends of several telescopic rods 401 are respectively welded to the bottom corners of the floating ring 403. A top rod 404 is welded on the top surface of the floating ring 403 near the telescopic rod 401. The top ends of several top rods 404 are evenly welded to the bottom surface of the top plate 405. An inclined support plate 406 is evenly welded in the middle of the floating ring 403. A buffer strip 407 is bonded to the top of the inclined support plate 406. The bottom end of the outer edge of the top plate 405 is hinged with a hollow floating plate 408. The hollow floating plate 408 is at the bottom of the horizontal state. The surface is flush with the bottom surface of the floating ring 403, and the two end surfaces of the buffer strip 407 are aligned with the two side surfaces of the hollow float 408, so that the hollow float 408 can remain horizontally floating on the water surface. The top surface of the hollow float 408 is inlaid with solar panels 409, and a waterproof box 410 is installed in the middle of the top surface of the top plate 405. A battery 411 is installed inside the waterproof box 410. The output end of the solar panel 409 is connected to the battery 411 through an inverter, and the input end of the electric push rod 209 is electrically connected to the output end of the battery 411 to ensure the normal operation of the electric push rod 209. An equipment board 412 is installed in the middle of the top surface of the waterproof box 410.

[0049] The working principle and usage process of the present invention are as follows: screw holes are provided on the top surface of the equipment plate 412 to install the required monitoring equipment. When the pontoon 1 is placed in the water when the water surface is calm, because the water tank 206 is full of air, the piston plate 210 is at the bottom, and the pontoon extends the frame 203 along the adjustment hole 201, and the extension frame 203 moves up along the adjustment hole 201 until the top corner of the extension frame 203 hits the limit card 202. The pontoon 1 floats on the water surface, the waterproof cloth 309 is full of air, the movable ring 302 slides up and down along the pontoon 1 and always floats on the water surface, and the solar panel 409 is in an inclined state and is placed on the top surface of the buffer bar 407 of the inclined support plate 406;

[0050] In bad weather, when the device sways violently, the electric push rod 209 pulls the piston plate 210 upward, and the waterproof rubber ring 211 ensures the sealing of the gap. After being filtered by the filter screen 214, the water enters the water tank 206 through the water-permeable hole 213. The water tank 206 is filled with water. At this time, the water tank 206 moves down along the extension frame 203 until the bottom end of the limit bar 207 contacts the bottom end of the limit hole 208. The extension frame 203 also moves down until the support plate 204 is at the bottom end of the bracket 205. The buoyancy and weight difference are reduced, the buoyancy box 1 is pulled down, the center of gravity moves down, and the buoyancy box 1 is in the water. Under the surface, it continues to move downward. After the telescopic rod 401 enters the water surface, the telescopic rod 401 extends, and the pontoon 1 is positioned lower until the hollow float plate 408 contacts the water surface and rotates to a horizontal position to provide buoyancy. At this time, the pontoon 1 no longer moves downward and cooperates with the center of gravity adjustment component 2 to further lower the center of gravity, so that the pontoon 1 is at a deeper depth. The water body under the water surface is calmer than the water surface, preventing the equipment from tipping over and being damaged, and improving stability. The floating ring 403 is flush with the water surface, the battery 411 is powered, and a monitoring device is installed on the top surface of the equipment plate 412 to maintain continuous monitoring;

[0051] The damping rod 304 and the angle plate 306 are combined into a regular dodecagonal ring and are located outside the pontoon 1. When the pontoon 1 is hit, the angle plate 306 is displaced, and the damping rod 304 and the buffer spring 308 are deformed to absorb the impact and reduce the impact on the pontoon 1. The waterproof cloth 309 is filled with air, which increases the contact area with the water surface and increases the buoyancy, making the device more stable.

[0052] The center of gravity adjustment component 2 can lower the center of gravity in bad weather to prevent the device from tipping over and being damaged. The auxiliary detection component 4 can be used alone or in conjunction with the center of gravity adjustment component 2 to make the pontoon 1 lower and the device more stable. The anti-collision component 3 always protects the pontoon 1 and provides better protection.

[0053] The buoyancy tank 1 can be provided with multiple compartments as needed, wherein the compartments are connected to the outside world through one-way valves. According to the requirements, the tester is placed in it to test multiple water quality data. Generally, more than 4 water quality data can be selected for water quality detection.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
