[0023] The following description is used to disclose the utility model so that those skilled in the art can realize the utility model. The preferred embodiments in the following description are only as examples, and other obvious variants can be thought of by those skilled in the art.

[0024] Referring to Figures 1-3 As shown in the figure, a water conservancy riverbed silt scouring condition monitoring device, including four mounting seats 1, the upper end of four mounting seats 1 is fixedly connected with support frame 2, the upper end of support frame 2 is provided with four groups of evenly distributed pull assembly 3;

[0025] Among them, pull assembly 3 includes two first supports 301 and two second supports 302 fixedly connected to the upper end of support frame 2 and steel cable 305, two first supports 301 are rotatably connected with second winding roller 304 between them, two second supports 302 are rotatably connected with first winding roller 303 between them, the outer side of one side first support 301 is fixedly installed with second motor 307 for driving second winding roller 304 to rotate, the outer side of one side second support 302 is fixedly installed with first motor 306 for driving first winding roller 303 to rotate, the upper end of support frame 2 is below first winding roller 303 and second winding roller 304 respectively and is provided with first through hole and second through hole, one end of steel cable 305 is wound on second winding roller 304, the other end of steel cable 305 is sequentially threaded through second through hole and first through hole and wound on first winding roller 303, the outer surface of steel cable 305 is fixedly connected with connecting ring 5, the inner side of four connecting rings 5 is fixedly connected with sealed box 4, the lower end of sealed box 4 is provided with sealed cavity 6, the inside of sealed cavity 6 is provided with silt monitor 7, the bottom end of silt monitor 7 is provided with sonar sensor 8, the slot of sealed cavity 6 is fixedly connected with transparent sealed window 9.

[0026] Further, the sonar sensor 8 is used to emit sound waves and receive reflected waves. When the sound wave pulses propagate in the water, they will encounter different substances or interfaces. According to the propagation characteristics of the sound waves, the sound waves will encounter the boundaries of different media, and part of the sound waves will be reflected back to the sensor. The sensor receives the sound wave signals reflected back from the objects or sediments. By measuring the time delay and reflection intensity of the reflected waves, the distance, shape and distribution of the reflected objects or sediments can be calculated, and the distribution of the sediment and underwater objects can be detected. The sediment monitor 7 emits laser or infrared light into the water, and then estimates the sediment concentration by measuring the scattered light after the light beam interacts with the sediment particles in the water. The combination of the sediment monitor 7 and the sonar sensor 8 can provide more comprehensive and accurate sediment information in water environment monitoring, and help better understand the behavior of sediment in the water body and its impact on the environment.

[0027] Further, the outer surface of the steel cable 305 is movably connected with the fixed anchor 308.

[0028] Further, the mounting seat 1 is provided with a mounting hole on the upper side, which facilitates the installation and fixation of the mounting seat 1.

[0029] Further, the fixed anchor 308 has sufficient weight to drive the steel cable 305 to sink. By throwing four fixed anchors 308 into the water, the fixed anchors 308 sink to the bottom of the water by their own gravity, which can form a moving path for the four steel cables 305. At this time, the excess steel cable 305 can be wound by the first winding roller 303 or the second winding roller 304, so that the steel cable 305 is in a tension state and can fix the sealed box 4.

[0030] Further, by driving the second winding roller 304 to unwind the steel cable 305 by the second motor 307, and driving the first winding roller 303 to wind the steel cable 305 by the first motor 306, the four connecting rings 5 can be moved downward, thereby driving the sealed box 4 to sink. Conversely, by driving the second winding roller 304 to wind the steel cable 305 by the second motor 307, and driving the first winding roller 303 to unwind the steel cable 305 by the first motor 306, the four connecting rings 5 can be moved upward, thereby driving the sealed box 4 to float. By changing the vertical position of the sealed box 4 in the water, the coverage range of the sonar sensor 8 can be adjusted to ensure that the sonar signal can cover the target area, thereby ensuring better monitoring effect. At the same time, the high adjustability can make the device better adapt to different depths of water, thereby enhancing the applicability of the device.

[0031] Further, the upper end of the support frame 2 away from one side of the lifting assembly 3 is provided with a solar cell panel 10, which is used to provide power support and ensure the long-term stable operation of the device.

[0032] Further, the upper end of the support frame 2 is provided with a distribution box 11 on the right side of the solar cell panel 10, and the distribution box 11 is used for power distribution to ensure the normal work of each part of the device.

[0033] Further, the upper end of the support frame 2 and the upper end of the sealing box 4 are both provided with a wire hole, and the wire is connected from the distribution box 11 to the automatic take-up reel, and then the wire is connected from the automatic take-up reel to the sediment monitor 7 and the sonar sensor 8 through the wire holes of the support frame 2 and the sealing box 4, so as to supply power to the sediment monitor 7 and the sonar sensor 8. The wire hole on the sealing box 4 is provided with a sealing ring to prevent water from seeping into the sealing box 4.

[0034] Further, the left mounting seat 1 and the right mounting seat 1 are fixedly connected with the reinforcing rod 12.

[0035] Further, the solar cell panel 10, the first motor 306 and the second motor 307 are electrically connected with the distribution box 11.

[0036] Working principle: when in use, the mounting seat 1 is installed on the fixed platform, and then the four fixed anchors 308 are thrown into the water, so that the fixed anchors 308 sink to the bottom of the water by their own gravity, and the four steel wires 305 form a moving path. At this time, the excess steel wire 305 is wound by the first winding roller 303 or the second winding roller 304, so that the steel wire 305 is in a tension state, and the sealing box 4 can be fixed. Then the second winding roller 304 is driven by the second motor 307 to unwind the steel wire 305, and the first winding roller 303 is driven by the first motor 306 to wind the steel wire 305, which can drive the four connecting rings 5 to move downward, thereby driving the sealing box 4 to sink. Conversely, the second winding roller 304 is driven by the second motor 307 to wind the steel wire 305, and the first winding roller 303 is driven by the first motor 306 to unwind the steel wire 305, which can drive the four connecting rings 5 to move upward, thereby driving the sealing box 4 to float. By changing the vertical position of the sealing box 4 in the water, the coverage range of the sonar sensor 8 can be adjusted to ensure that the sonar signal can cover the target area, thereby ensuring better monitoring effect. At the same time, the height adjustability can make the device better adapt to different depths of water, thereby enhancing the applicability of the device.
