[0007] Furthermore, the number of the slides is four, and the four slides are arranged in a circle with the floating frame as the center. The inner wall of the linkage frame is fixedly connected to the surface of the slide rod, and the linkage frame extends from one end of the rectangular frame to above the floating frame. The rectangular frame is symmetrically arranged with the lifting frame as the center.

[0008] Furthermore, the top of the rectangular frame extends above the slide plate, the bent frame is located above the expansion plate, the surface of the extrusion plate contacts the surface of the expansion plate, and the bottom of the expansion plate extends below the floating frame.

[0012] The present invention has the following beneficial effects: When the floating frame of the present invention is operating inside the river, the water quality information contacted by the detection rod will be transmitted to the inside of the detection device for analysis and processing.

When the limiting ring moves, the triangular ring is pushed to clean the surface of the sieve frame to prevent impurities from adhering to the surface of the sieve frame and affecting the monitoring effect of the detection rod. Through holes are provided on the surface of the triangular ring, and impurities cleaned by the triangular ring are quickly discharged through the through holes to prevent impurities from accumulating on the surface of the triangular ring and affecting the cleaning effect.

[0021] The bottom of the detection rod 7 passes through the floating frame 1 and extends to the bottom outer end of the floating frame 1. The bottom of the slide rod 16 passes through the floating frame 12 and extends to the inside of the floating frame 12. The sealing ring 15 is located inside the floating frame 12. The number of rubber rings 14 is set to two. When the floating frame 1 of the present invention is operating inside the river, the water quality information contacted by the detection rod 7 will be transmitted to the inside of the detection device 6 for analysis and processing. When the floating frame 1 is operating in a place where there is a ship, the electric push rod 10 is started to push the cross 11 to move upward. When the cross 11 moves upward, it will push the sealing ring 15 to move up inside the floating frame 12 through the slide rod 16. The sealing ring 15 and the rubber ring 1 The movement of the floating frame 12 in cooperation with each other will generate negative pressure, which will be transmitted to the river through the water inlet pipe 13. At this time, the river water in the river will enter the inside of the floating frame 12 through the negative pressure. When the river water enters the inside of the floating frame 12, the weight of the floating frame 1 will be increased, thereby improving the stability of the floating frame 1 during operation. At the same time, the increased weight of the floating frame 12 will drive the floating frame 1 to sink, reducing the height of the floating frame 1 exposed above the water surface, thereby reducing the impact of the waves generated by the passing ship. The two rubber rings 14 are symmetrically arranged with the sealing ring 15 as the center, and the ends of the two rubber rings 14 away from the sealing ring 15 are in contact with the inner wall of the floating frame 12.

The surface of the slide plate 21 is slidably connected to a lifting frame 25, the surface of the lifting frame 25 is fixedly connected to an extrusion plate 24, the surface of the lifting frame 25 is fixedly connected to a rectangular frame 27, the top of the rectangular frame 27 is fixedly connected to a linkage frame 20, the upper surface of the slide plate 21 is hinged with an expansion plate 22, the end of the expansion plate 22 away from the slide plate 21 is fixedly connected to a floating block 23, the upper surface of the slide plate 21 is fixedly connected to a bracket 28, the top of the bracket 28 is fixedly connected to a bent frame 29, the surface of the bent frame 29 is fixedly connected to a spring clip 26, and the end of the spring clip 26 away from the bent frame 29 is fixedly connected to the surface of the expansion plate 22.

[0023] There are four slide plates 21, which are arranged around the floating frame 12 as the center circle. The inner wall of the linkage frame 20 is fixedly connected to the surface of the slide bar 16. When the slide bar 16 of the present invention moves upward, the connection between the linkage frame 20 and the rectangular frame 27 pushes the lifting frame 25 to move on the surface of the slide plate 21. When the lifting frame 25 moves, it pushes the extrusion plate 24 to squeeze the expansion plate 22. At this time, the extrusion plate 24 will push the floating block 23 to expand to the end away from the floating frame 12 and move upward through the expansion plate 22. When the expansion plate 22 pushes the floating block 23 to expand, the floating block 23 will support the floating frame 1, further improving the stability of the detection device 6 during operation. When the expansion plate 22 expands, the expansion plate 22 will squeeze the spring piece 26 to produce deformation. When the extrusion plate 24 is separated from the surface of the expansion plate 22, the expansion plate 22 will be reset by the elasticity of the spring piece 26, and the end of the linkage frame 20 away from the rectangular frame 27 extends to the top of the floating frame 12, and the rectangular frame 27 is symmetrically arranged around the lifting frame 25.

[0026] The surface of the support rod 32 contacts the inner wall of the through hole 35. When the rectangular frame 27 of the present invention moves, it utilizes the connection between the connecting frame 30 and the driving plate 31 to push the limiting ring 33 to move upward. When moving, the limiting ring 33 pushes the triangular ring 34 to clean the surface of the sieve frame 5 to prevent impurities from adhering to the surface of the sieve frame 5 and affecting the monitoring effect of the detection rod 7.

[0028] When in use, when the floating frame 1 is operating inside the river, the water quality information contacted by the detection rod 7 will be transmitted to the inside of the detection device 6 for analysis and processing. When the floating frame 1 is operating in a place where there is a ship, the electric push rod 10 is started to push the cross 11 to move upward. When the cross 11 moves upward, it will push the sealing ring 15 to move upward inside the floating frame 12 through the sliding rod 16. The sealing ring 15 and the rubber ring 14 cooperate with each other to move inside the floating frame 12 to generate negative pressure, and the negative pressure will be transmitted to the river through the water inlet pipe 13. At this time, the river water in the river will enter the inside of the floating frame 12 through the negative pressure. When the river water enters the inside of the floating frame 12, the weight of the floating frame 1 will be increased, thereby improving the stability of the floating frame 1 during operation. At the same time, the increase in the weight of the floating frame 12 will drive the floating frame 1 to sink, reducing the height of the floating frame 1 exposed above the water surface, thereby reducing the impact of the waves generated by the ship passing by. When the sliding rod 16 moves upward, it pushes the lifting frame 25 to move on the surface of the slide plate 21 through the connection between the linkage frame 20 and the rectangular frame 27. When the lowering frame 25 moves, the extrusion plate 24 pushes the expansion plate 22 to extrude the expansion plate 22. At this time, the extrusion plate 24 will push the floating block 23 to expand and move upward to the end away from the floating frame 12 through the expansion plate 22. When the expansion plate 22 pushes the floating block 23 to unfold, the floating block 23 will support the floating frame 1, further improving the stability of the detection device 6 during operation. The expansion plate 22 will squeeze the spring piece 26 to produce deformation when expanding. When the extrusion plate 24 is separated from the surface of the expansion plate 22, the expansion plate 22 will be reset by the elasticity of the spring piece 26. When the rectangular frame 27 moves, the connection between the connecting frame 30 and the driving plate 31 is used to push the limiting ring 33 to move upward.

The impurities cleaned by the triangular ring 34 will be quickly discharged through the through hole 35 to prevent impurities from accumulating on the surface of the triangular ring 34 and affecting the cleaning effect.
