And a piston stroke limiting pile 01 is arranged at one end, close to the control pipe 15, in the arc-shaped piston channel 31.
The detailed working method, the working principle and the technical progress of the scheme are organized as follows:
before the mechanism is launched into water, the original air in the vacuum sampling cavity 26 is pumped away through the air pumping connector 9 by an external air pumping device, so that the vacuum sampling cavity 26 is in a vacuum negative pressure state, and the air pumping connector 9 is blocked by the manual valve 10, so that the vacuum sampling cavity 26 is in the vacuum negative pressure state before the sampler 8 is launched into water;
in the initial state, the whole sampler 8 is immersed in water in a horizontal posture and is positioned at the height of the water surface, the included angle formed by the sampling pipe 11 of each sampling unit 4 and the control pipe 15 is a (as shown in fig. 8) in the initial state, the sampling nozzle 12 is not communicated with the vacuum sampling cavity 26, the traction rope 1 is in a stretched and unstressed state, and the first piston 34 is in contact with and pushes against the annular limiting inner edge 33 under the elastic pushing and pressing constraint of the spring 36; because the arc-shaped piston channel 31 and the linear hydraulic oil channel 32 are filled with hydraulic oil, the first piston 34 and the second piston 30 are in a linkage state, when the position of the first piston 34 is elastically pressed and restrained by the spring 36, the position of the second piston 30 in the arc-shaped piston channel 31 is also restrained, when the position of the second piston 30 in the arc-shaped piston channel 31 is restrained, the size a of an included angle formed by the sampling tube 11 and the control tube 15 of the sampling unit 4 is in a relatively stable state; the combination of the three parts of the third piston 28, the fourth piston 25 and the linkage rod 27 is recorded as an assembly; because the two ends of the sampling tube 11 are through, and the two ends of the sampling tube 11 are communicated with water with the same depth, the water pressure at the two ends of the assembly formed by the three components of the third piston 28, the fourth piston 25 and the linkage rod 27 is equal, so that the force in the axial direction of the assembly formed by the three components of the third piston 28, the fourth piston 25 and the linkage rod 27 is balanced, and the static friction between the third piston 28 and the fourth piston 25 and the inner wall of the sampling tube 11 is enough to maintain the stability without external force intervention, so that the assembly formed by the three components of the third piston 28, the fourth piston 25 and the linkage rod 27 cannot displace in the axial direction on the premise that the included angle formed by the sampling tube 11 and the control tube 15 is a;
after the unmanned ship 6 runs to a preset sampling area, controlling the winch 70 to continuously release the outgoing line 2, further enabling the sampler 8 to gradually sink to a preset depth from the height of the water surface, and further enabling each sampling unit 4 to sink to the preset depth in a horizontal posture;
in the process that the sampling unit 4 sinks, the water pressure borne by the second piston 30 increases, when the sampling unit 4 reaches a certain depth, the force of the second piston 30 pushing the hydraulic oil in the arc-shaped piston channel 31 in the counterclockwise direction under the action of the water pressure is enough to overcome the jacking force of the spring 36 in the linear piston channel 35, so that the second piston 30 performs counterclockwise displacement in the arc-shaped piston channel 31, under the linkage of the hydraulic oil, the first piston 34 feeds in the linear piston channel 35 in the direction close to the fixed pulley 16, so that the first piston 34 further compresses the spring 36 and air in the linear piston channel 35, and meanwhile, the counterclockwise displacement of the second piston 30 in the arc-shaped piston channel 31 drives the arc-shaped piston pull rod 29 to gradually reduce the included angle formed between the sampling tube 11 and the control tube 15;
as the sampling unit 4 continues to sink, the spring 36 and the air in the linear piston channel 35 will be further compressed by the first piston 34 until the angle between the sampling tube 11 and the control tube 15 changes from a to b (as shown in fig. 9), which indicates that the predetermined depth has been reached, and at this time, the piston stroke-limiting stud 01 limits the second piston 30 to continue to move counterclockwise;
in the process that the size of an included angle formed between the sampling tube 11 and the control tube 15 is changed from a to b, according to the change of the geometric relation, the length of the third section 1.3 of the hauling rope is not changed, the second section 1.2 of the hauling rope is lengthened, and as the total length of the hauling rope 1 is not changed, the first section 1.1 of the hauling rope is shortened; therefore, in the process that the size of the included angle formed between the sampling tube 11 and the control tube 15 is changed from a to b, as the first section 1.1 of the traction rope is shortened, the first section 1.1 of the traction rope pulls the assembly formed by the third piston 28, the fourth piston 25 and the linkage rod 27 to be close to the fixed pulley 16 along the axial direction and displaces for a certain distance, so that the sampling nozzle 12 is communicated with the vacuum sampling cavity 26, and at the moment, external water rapidly floods into the vacuum sampling cavity 26 through the sampling nozzle 12 under the action of water pressure; thus, the sample collection process of the sampling unit 4 is completed;
because of the one-way valve in the sampling nozzle 12, the sample rushing into the vacuum sampling cavity 26 cannot flow out; and finally, controlling the winch 70 to continuously withdraw the outgoing line 2, gradually pulling the underwater sampler 8 from the deep water position to the water surface, driving the unmanned ship 6 to the shore, disassembling the underwater sampler 8 which has collected the deep water sample by a worker, and finally opening the manual valve 10 to pump the sample water out through the air suction joint 9.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
