[0056] Embodiment 2

[0057] As shown in Figures 1-4 , in the case that other parts are the same as those of embodiment 1, the difference between the present embodiment and embodiment 1 is that the sand collecting pipe switching mechanism comprises a rotating shaft 4, the rotating shaft 4 is located in the center of the monitoring cylinder 9, a bearing 7 is sleeved on the left end of the rotating shaft 4, the inner ring of the bearing 7 is fixedly connected with the rotating shaft 4, the outer ring of the bearing 7 is fixedly connected with one end of a plurality of first connecting rods 3, the other end of the first connecting rods 3 is fixedly connected with the sand collecting pipes 8, a cover plate 5 is arranged on the right side of the rotating shaft 4, the rotating shaft 4 is fixedly connected with the center of the cover plate 5, a water inlet hole 11 is formed in the edge of the cover plate 5, a torsional spring 6 is sleeved on the rotating shaft 4, the left end of the torsional spring 6 is fixedly connected with the outer ring of the bearing 7, the right end of the torsional spring 6 is fixedly connected with the cover plate 5, a sealing cover 12 is arranged on the water inlet hole 11, the sealing cover 12 covers the water inlet hole 11, and the edge of the sealing cover 12 is connected with the cover plate 5 through a spring hinge 13.

[0058] The sand collecting mechanism comprises a fixed disc 15, the edge of the fixed disc 15 is fixedly connected with the inner wall of the sand collecting pipe 8, a plurality of water discharge holes 16 are formed through the fixed disc 15, a guide pipe 21 is arranged through the center of the fixed disc 15, the guide pipe 21 is fixedly connected with the fixed disc 15, a guide rod 14 is arranged in the guide pipe 21, the guide rod 14 is in sliding fit with the guide pipe 21, a sand blocking assembly is sleeved on the guide rod 14, a buffer spring 20 is arranged between the fixed disc 15 and the sand blocking assembly, the buffer spring 20 is sleeved on the guide rod 14, the left end of the buffer spring 20 is fixedly connected with the fixed disc 15, and the right end of the buffer spring 20 is fixedly connected with the sand blocking assembly.

[0059] The sand blocking assembly comprises a support tube 18 sleeved on the guide rod 14, a plurality of second connecting rods 19 arranged between the support tube 18 and the guide rod 14, one end of each second connecting rod 19 being fixedly connected with the support tube 18 and the other end being fixedly connected with the guide rod 14, the outer wall of the support tube 18 being in sliding fit with the inner wall of the sand collecting tube 8, the left end of the support tube 18 being provided with a sand blocking net 17, the sand blocking net 17 being fixedly connected with the support tube 18 and sleeved on the guide rod 14, the left end of the sand collecting tube 8 being provided with a one-way valve 10, so that the water flow can only enter through the right end of the sand collecting tube 8 and flow out through the left end of the sand collecting tube 8, the outer wall of the monitoring cylinder 9 being provided with a fixing plate 2, the fixing plate 2 being fixedly connected with the monitoring cylinder 9, a plurality of connecting screws 1 being arranged on the fixing plate 2, the fixing plate 2 being connected with the ship body through the connecting screws 1, and the cover plate 5 abutting against the right end of the monitoring cylinder 9 and the right end of the sand collecting tube 8 abutting against the cover plate 5.

[0060] In use, the fixing plate 2 is connected with the ship bottom through the connecting screws 1, so that the device is fixed on the ship bottom, the guide rod 14 aligned with the water inlet hole 11 on the cover plate 5 is pushed away from the sealing cover 12 and inserted into the water inlet hole 11 under the elastic force of the buffer spring 20, the guide rod 14 extends out of the monitoring cylinder 9, the guide rod 14 clamps the cover plate 5, and the cover plate 5 cannot rotate under the torsional force of the torsional spring 6.

[0061] The other guide rods 14 not aligned with the water inlet hole 11 abut against the cover plate 5 under the elastic force of the buffer spring 20.

[0062] When the ship sails in the middle of the river, the water flow enters the sand collecting tube 8 aligned with the water inlet hole 11 on the cover plate 5 through the water inlet hole 11, and the sand is intercepted in the sand collecting tube 8 by the sand blocking net 17, and the water is discharged out of the sand collecting tube 8 through the drain hole 16 and the one-way valve 10.

[0063] With the increasing amount of sand in the sand collecting tube 8, the sand blocking net 17 is gradually blocked, the resistance of the water flow through the sand blocking net 17 increases, and the sand blocking net 17, the support tube 18, the second connecting rod 19 and the guide rod 14 synchronously move left under the impact of the water flow to compress the buffer spring 20, when the guide rod 14 completely moves into the sand collecting tube 8, the guide rod 14 no longer clamps the cover plate 5, and the cover plate 5 rotates under the action of the torsional spring 6, when the water inlet hole 11 on the cover plate 5 is aligned with the next guide rod 14, the guide rod 14 is pushed away from the sealing cover 12 and inserted into the water inlet hole 11 under the elastic force of the buffer spring 20, the guide rod 14 extends out of the monitoring cylinder 9, and the cover plate 5 is clamped again.

[0064] At this time, the water flow enters the new sand collecting tube 8, and the process is repeated, and when the sand collecting tube 8 is filled with sand, the water flow enters the new sand collecting tube 8.

[0065] When it is necessary to observe the changes in sediment content in a certain section of the river, the boat is made to travel a fixed distance at a fixed speed in that section, and then the amount of sediment collected is observed. For example, under normal circumstances, five sediment collection pipes can be filled with sediment. When six or more sediment collection pipes are filled with sediment, it means that the sediment content exceeds the standard. The more sediment collection pipes are filled with sediment, the more serious the exceedance of sediment content.

[0066] Example 3

[0067] like Figure 1 As shown, while all other parts are the same as in Example 2, the difference between this example and Example 2 is that both the monitoring cylinder 9 and the fixing plate 2 are made of aluminum alloy. Using aluminum alloy not only improves the strength of the device but also effectively prevents rusting.

[0068] Example 4

[0069] like Figures 1-7 As shown, while other parts are the same as in Embodiment 2, the difference between this embodiment and Embodiment 2 is that: the fixing plate 2 has multiple square through holes 22, and the connecting screw 1 is located in the square through holes 22.

[0070] By setting a square through hole 22 and placing the connecting screw 1 in the square through hole 22, the device has a certain amount of movement, which allows the device to be buffered under the impact of water flow during use, thus preventing damage to the device.

[0071] Example 5

[0072] like Figures 1-7 As shown, while all other parts are the same as in Example 2, the difference between this example and Example 2 is that:

[0073] A one-way bearing 23 is fitted onto the connecting screw 1. The inner ring of the one-way bearing 23 is fixedly connected to the connecting screw 1. A drive gear 24 is fitted onto the outer ring of the one-way bearing 23. The drive gear 24 is fixedly connected to the one-way bearing 23. A track 25 is provided on the left side of the drive gear 24. The surface of the track 25 is provided with a number of teeth 26. The track 25 is fixedly connected to the left side of the square through hole 22. Two limiting baffles 27 are provided on both the left and right sides of the drive gear 24. The drive gear 24 is located between the two limiting baffles 27, thereby restricting the drive gear 24 inside the square through hole 22.

[0074] After connecting the connecting screw 1 with the ship body, the fixed plate 2 shakes up and down under the water flow impact. When the fixed plate 2 moves up, if the tooth 26 touches the driving gear 24 and engages with it, the tooth 26 drives the driving gear 24 to rotate clockwise, the driving gear 24 drives the one-way bearing 23 to rotate clockwise, at this time, the one-way bearing 23 is in the locked state, the one-way bearing 23 drives the connecting screw 1 to rotate clockwise synchronously, so that the connecting screw 1 is more firmly connected with the ship body, preventing the connecting screw from falling off.

[0075] When the fixed plate 2 moves down, if the tooth 26 touches the driving gear 24 and engages with it, the tooth 26 drives the driving gear 24 to rotate counterclockwise, the driving gear 24 drives the one-way bearing 23 to rotate counterclockwise, at this time, the one-way bearing 23 is not in the locked state, the one-way bearing 23 cannot drive the connecting screw 1 to rotate counterclockwise synchronously.

[0076] Therefore, when the device is used, with the up and down shaking of the fixed plate 2, the connection between the connecting screw 1 and the ship body becomes more tightly, thereby effectively preventing the connecting screw 1 from falling off.

[0077] Example 6

[0078] As Figures 1-7 shown, in the case that other parts are the same as example 2, the difference between this embodiment and example 2 is that the connecting screw 1 is provided with a knob 28 at one end, the knob 28 is fixedly connected with the connecting screw 1. The surface of the connecting screw 1 is coated with rust-proof paint. By setting the knob 28, the connecting screw 1 can be more conveniently screwed into the ship body. By coating the surface of the connecting screw 1 with rust-proof paint, the rust of the connecting screw 1 can be prevented, and the strength of the connecting screw 1 can be ensured.

[0079] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above examples, the above examples and the description in the specification are only to illustrate the principles of the present application, and various changes and improvements can be made to the present application without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
