With the continuous development of deep-sea technology and equipment, the large-scale development of deep-sea mineral resources by mankind is accelerating the transition from the exploration stage to the development stage. As a country with great demand for resources, my country is bound to take the lead in the commercial development of deep-sea resources.

Therefore, this patent will focus on the breakthrough of plume redeposition monitoring technology for deep-sea mining, and effectively support my country's active participation in the international competition for the development of deep-sea mineral resources. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The design of the first positioning column allows the lifting plate to move smoothly in the vertical direction. The rotating drive mechanism drives the lead screw to rotate, thereby changing the height of the lifting plate and the rotating sleeve. The height of the first support plate and the measuring floating plate can be adjusted. The design of the elastic mechanism allows the measuring floating plate to be elastically connected to the first support plate. The sediment covering base is placed at a specified position. The measuring floating plate contacts the top of the sediment covering base. When monitoring the plume redeposition thickness, the first support plate is first driven upward. The upward distance of the first support plate is S. At this time, the distance between the distance measuring sensor and the inner wall of the bottom of the groove is H. When monitoring is required, the first support plate is driven downward. The downward distance is S. Since the plume redeposition thickness deposited on the sediment covering base is no longer O at this time, when the measuring floating plate contacts the plume redeposition, the measuring floating plate stops moving downward. The downward distance of the first support plate is still S. The first support plate and the plug plate move relative to the measuring floating plate. The distance the first support plate moves relative to the measuring floating plate is the plume redeposition thickness. Thickness, at this time, the distance between the distance sensor and the inner wall of the bottom of the groove is measured by the distance measuring sensor as H1, and the value of H minus H1 is X1, and X1 is the value of the plume redeposition thickness monitored for the first time. After the first monitoring is completed, the first support plate is driven to move up, and the value of the upward movement is the sum of the values ​​of S and X1. When the second monitoring is required, the first support plate is moved down, and the downward distance value is S. The measuring float contacts the plume redeposition again, and the first support plate and the plug plate move relative to the movable plate and the measuring float again. At this time, the distance between the distance sensor and the inner wall of the bottom of the groove is measured by the distance measuring sensor as H2, and the value of H minus H2 is X2, and X2 is the thickness increased by the second time interval. At this time, the plume redeposition thickness value is the sum of the values ​​of X1 and X2. After the second monitoring is completed, the first support plate is driven to move up, and the value of the upward movement is the sum of the values ​​of S and X2. Repeat the above steps repeatedly to obtain the value of the plume redeposition thickness monitored each time. The operation steps are simple and convenient, and the value of the plume redeposition thickness can be intuitively and accurately understood;

[0017] (2) The first motor drives the gear to rotate, and then the gear ring and the rotating sleeve are driven to rotate relative to the lifting plate, so that the first support plate can be rotated, thereby changing the positions of the first support plate and the measuring floating plate, and the plume redeposition thickness can be monitored at different positions on the sediment-covered base;

[0018] (3) By designing the compression spring, the measuring floating plate is elastically connected to the first supporting plate. When the first fixed plate is manually driven to move, the first tension spring is in a tensioned state, so that one end of the limiting column is separated from the first limiting groove, and the fixing relationship between the supporting ring and the second positioning column is released. When the measuring floating plate is manually driven to move downward, the second positioning column is separated from the first supporting plate and the supporting ring, and the compression spring sleeved on the outside of the second positioning column can be taken out, which is convenient for replacing compression springs with different elastic coefficients;

[0019] (4) The second motor drives the second fixed disk to rotate, thereby causing the plug rod to drive the third fixed disk to rotate, thereby causing the worm to rotate. Through the cooperation of the worm and the worm wheel, the worm can drive the worm wheel to rotate, thereby causing the lead screw to rotate. The first bolt is manually driven to rotate, so that the first bolt is disengaged from the first mounting plate and the sediment covering base, thereby releasing the fixed relationship between the first mounting plate and the sediment covering base. The first mounting plate is manually driven to move away from the sediment covering base, so that the second motor moves away from the worm, thereby causing the plug rod to disengage from the socket, thereby causing the second motor to be pulled out of the control chamber, thereby facilitating the replacement and maintenance of the second motor.

[0020] (5) Manually drive the second bolt to rotate, so that the second bolt disengages from the thread groove, and releases the fixed relationship between the turntable and the lifting plate. Manually drive the turntable to rotate, so that the turntable drives the rotating shaft to rotate, and then the cam rotates. The cam no longer supports the movable seat. At this time, the second tension spring is in a tensioned state, and then the second tension spring drives the movable seat to move, so that the first motor drives the gear to move, and then the gear no longer meshes with the gear ring, so that the gear moves between the two lifting plates, and the gear and the first motor no longer block the vertical movement of the connecting ring and the first bearing.

[0021] (6) Manually drive the third bolt to rotate so that the third bolt is separated from the second mounting plate and the lifting plate, thereby releasing the relationship between the lifting plate and the connecting ring. Manually drive the rotating sleeve to move upward so that the first bearing and the connecting ring are moved upward, thereby causing the limit plate to be separated from the second limit groove, so that the rotating sleeve is no longer mounted on the outside of the two lifting plates, thereby exposing the first motor located between the two lifting plates, thereby facilitating replacement and maintenance of the first motor.

[0043] Working principle: During operation, the lifting plate 5 is moved smoothly in the vertical direction through the design of the first positioning column 3, and the lead screw 2 is driven to rotate through the rotary drive mechanism, thereby changing the height of the lifting plate 5 and the rotating sleeve 4, and the height of the first support plate 11 and the measuring float 12 can be adjusted. The measuring float 12 is elastically connected to the first support plate 11 through the design of the elastic mechanism, and the sediment covering base 1 is placed at a specified position. The measuring float 12 contacts the top of the sediment covering base 1. When monitoring the plume redeposition thickness, the first support plate 11 is first driven to move upward, and the upward movement distance of the first support plate 11 is S. At this time, the distance between the distance sensor 16 and the inner wall of the bottom of the groove 15 is H, and it is necessary to During monitoring, the first support plate 11 is driven to move downward, and the downward distance is S. Since the plume redeposition thickness deposited on the sediment-covered base 1 is no longer O at this time, when the measuring float 12 contacts the plume redeposition, the measuring float 12 stops moving downward, and the downward distance of the first support plate 11 is still S. The first support plate 11 and the plug plate 14 move relative to the measuring float 12, and the distance the first support plate 11 moves relative to the measuring float 12 is the plume redeposition thickness. At this time, the distance between the distance sensor 16 and the inner wall of the bottom of the groove 15 measured by the distance measuring sensor 16 is H1, and the value of H minus H1 is X1, which is the value of the plume redeposition thickness monitored for the first time. After the first monitoring is completed, the first support plate 11 is driven to move upward, and the upward movement is stopped. The value is the sum of the values ​​of S and X1. When the second monitoring is required, the first support plate 11 moves downward, and the value of the downward movement is S. The measuring float 12 contacts the plume redeposition again. The first support plate 11 and the plug plate 14 move relative to the movable plate 13 and the measuring float 12 again. At this time, the distance between the distance sensor 16 and the inner wall of the bottom of the groove 15 is measured by the distance sensor 16 as H2. The value of H minus H2 is X2. X2 is the thickness increased during the second time interval. At this time, the plume redeposition thickness value is the sum of the values ​​of X1 and X2. After the second monitoring is completed, the first support plate 11 is driven to move upward, and the value of the upward movement is the sum of the values ​​of S and X2. The above steps are repeated repeatedly to obtain the plume redeposition thickness monitored each time. The operation steps are simple and convenient, and the value of the plume redeposition thickness can be intuitively and accurately understood. The first motor 10 drives the gear 9 to rotate, and then the gear 9 drives the gear ring 8 and the rotating sleeve 4 to rotate relative to the lifting plate 5, so that the first support plate 11 can be rotated, and then the positions of the first support plate 11 and the measuring floating plate 12 are changed, and the plume redeposition thickness at different positions on the sediment covering base 1 can be monitored. Through the design of the compression spring 20, the measuring floating plate 12 is elastically connected to the first support plate 11, and the first fixed plate 24 is manually driven to move. The first tension spring 25 is in a tensioned state, so that one end of the limiting column 22 is separated from the first limiting groove 23, and the fixed relationship between the support ring 21 and the second positioning column 19 is released.The measuring float 12 is manually driven to move downward, so that the second positioning column 19 is separated from the first support plate 11 and the support ring 21, and the compression spring 20 sleeved on the outside of the second positioning column 19 can be taken out, which is convenient for replacing the compression spring 20 with different elastic coefficients. The second motor 31 drives the second fixed disk 32 to rotate, and then the insertion rod 33 drives the third fixed disk 37 to rotate, so that the worm 28 rotates. Through the cooperation of the worm 28 and the worm wheel 26, the worm 28 can drive the worm wheel 26 to rotate, and then the lead screw 2 rotates, and the first worm 28 is manually driven. The bolt 36 rotates, so that the first bolt 36 is separated from the first mounting plate 35 and the sediment covering base 1, and the fixed relationship between the first mounting plate 35 and the sediment covering base 1 can be released. The first mounting plate 35 is manually driven to move away from the sediment covering base 1, so that the second motor 31 moves away from the worm 28, and then the plug rod 33 is separated from the plug hole 34, so that the second motor 31 is pulled out of the control chamber 27, which is convenient for replacing and repairing the second motor 31. The second bolt 45 is manually driven to rotate, so that the second bolt 45 is separated from the thread The second tension spring 40 is in a tensioned state, and the second tension spring 40 drives the movable seat 38 to move, so that the first motor 10 drives the gear 9 to move, and the gear 9 is no longer meshed with the gear ring 8, so that the gear 9 moves between the two lifting plates 5, and the gear 9 and the first motor 10 no longer block the vertical movement of the connecting ring 6 and the first bearing 7. The third bolt 50 is manually driven to rotate, so that the third bolt 50 is separated from the second mounting plate 49 and the lifting plate 5, and the relationship between the lifting plate 5 and the connecting ring 6 is released. The rotating sleeve 4 is manually driven to move up, so that the first bearing 7 and the connecting ring 6 are moved up, and then the limiting plate 47 is separated from the second limiting groove 48, so that the rotating sleeve 4 is no longer sleeved on the outside of the two lifting plates 5, so that the first motor 10 located between the two lifting plates 5 can be exposed, which is convenient for replacing and repairing the first motor 10. ,
