[0030] See also Figure 1The embodiment of the present application provides a sampling device, which can ensure the safety of deep-sea sampling and improve the sampling efficiency. The sampling device includes a transmission member 100 and a first sampling member 310, the first sampling member 310 is movably connected to the transmission member 100, and the transmission member 100 is used to rotate under the action of a driving force to drive the first sampling member 310 to reciprocate along the length direction of the transmission member 100. Optionally, the first sampling member 310 can be an impact head.

[0031] The first sampling member 310 in the embodiment of the present application is arranged along the length direction (i.e. Figure 1 When the submersible reciprocates in the deep sea (in the X-axis direction), force can be applied to the rocks, minerals or other materials to be collected in the deep sea for multiple times to carry out sampling. There is no need to repeatedly drive the deep-sea manned submersible with power to cause the manipulator at the front end of the deep-sea manned submersible to impact. Therefore, the deep-sea manned submersible can be prevented from colliding during deep-sea sampling, and the personnel and equipment on the deep-sea manned submersible can be prevented from being affected by the impact force of the impact and falling into danger, thereby ensuring the safety of deep-sea sampling and improving the sampling efficiency.

[0032] Alternatively, see Figure 1 and Figure 2 A slide groove 131 extending along the axial direction of the transmission member 100 is provided on the transmission member 100, and a sliding shaft 320 is provided on the first sampling member 310. The sliding shaft 320 is embedded in the slide groove 131, and the sliding shaft 320 is movable along the extension direction of the slide groove 131, so that when the transmission member 100 rotates, the first sampling member 310 is driven to extend or retract through the sliding shaft 320.

[0033] It is understandable that the first sampling member 310 is used for sampling when it is extended, and the first sampling member 310 can be prepared for the next extension after it is recovered. In this way, sampling can be achieved by using this reciprocating motion, without repeatedly driving the deep-sea manned submersible with power to cause the manipulator at the front end of the deep-sea manned submersible to impact, thereby ensuring the safety of sampling and improving the sampling efficiency. Figure 1 or Figure 3 The transmission member 100 is cylindrical, and the slide groove 131 is arranged on the cylindrical surface of the transmission member 100 .

[0034] Optionally, in some embodiments, the slide groove 131 includes N linear grooves and N arc-shaped grooves, the linear grooves are parallel to the axis of the transmission member 100, the linear grooves and the arc-shaped grooves are alternately arranged, and the linear grooves and the arc-shaped grooves are connected end to end in sequence, the sampling device also includes an elastic member 340, one end of the elastic member 340 is connected to the first sampling member 310, the transmission member 100 has a first end 110 and a second end 120 arranged along its length direction, the slide shaft 320 slides along the arc-shaped groove toward the direction close to the second end 120 when the transmission member 100 rotates, so as to compress the elastic member 340 and drive the first sampling member 310 to recover, and the slide shaft 320 is also used to slide along the linear groove toward the direction close to the first end 110 under the action of the restoring force of the elastic member 340 when the transmission member 100 stops rotating, so as to drive the first sampling member 310 to extend, thereby hammering the material to be collected. Wherein, N is a natural number greater than 0, that is, N can be 1, 2, 3, ...

[0035] Exemplarily, the value of N is 1, that is, the slide groove 131 includes a straight groove and an arcuate groove, the two ends of the arcuate groove are respectively connected to the two ends of the straight groove, and the arcuate groove spirally rotates around the transmission member 100 for one circle.

[0036] In another exemplary embodiment, N takes a value greater than 1, that is, the slide groove 131 includes a plurality of equal numbers of straight grooves and a plurality of arcuate grooves, the plurality of straight grooves are arranged at intervals along the circumference of the transmission member 100, and each arcuate groove sequentially connects the beginning and the end of two adjacent straight grooves.

[0037] Optionally, in some embodiments, the value of N is 2, that is, two linear grooves and two arc-shaped grooves are each provided, and the two linear grooves are symmetrically arranged along the axis of the transmission member 100 .

[0038] For example, see Figure 4 and Figure 5 , the two straight grooves are respectively the first straight groove 1311a and the second straight groove 1311b, and the two arc grooves are respectively the first arc groove 1312a and the second arc groove 1312b. The end of the first straight groove 1311a close to the first end 110 of the transmission member 100 is connected to one end of the first arc groove 1312a, the other end of the first arc groove 1312a is connected to one end of the second straight groove 1311b close to the second end 120 of the transmission member 100, the other end of the second straight groove 1311b (i.e. the end of the second straight groove 1311b close to the first end 110 of the transmission member 100) is connected to one end of the second arc groove 1312b, and the other end of the second arc groove 1312b is connected to one end of the first straight groove 1311a close to the second end 120 of the transmission member 100.

[0039] It can be understood that, under the transmission action of the transmission member 100, the sliding shaft 320 moves from one end where the first arc-shaped groove 1312a is connected to the first straight groove 1311a (i.e., the end of the first arc-shaped groove 1312a close to the first end 110 of the transmission member 100) to one end where the first arc-shaped groove 1312a is connected to the second straight groove 1311b (i.e., the end of the first arc-shaped groove 1312a close to the second end 120 of the transmission member 100), and when the sliding shaft 320 moves in the first arc-shaped groove 1312a, the first sampling member 310 moves linearly from the first end 110 to the second end 120 (i.e., the first sampling member 310 moves along the negative direction of the X-axis for recovery) and compresses the elastic member 340. When the sliding shaft 320 moves to one end of the second linear groove 1311b close to the second end 120 of the transmission member 100, the elastic member 340 recovers and drives the sliding shaft 320 to move from one end of the second linear groove 1311b close to the second end 120 of the transmission member 100 to one end of the second linear groove 1311b close to the first end 110 of the transmission member 100 (i.e., the elastic member 340 drives the sliding shaft 320 to move in the second linear groove 1311b along the positive direction of the X-axis), thereby driving the first sampling member 310 to move linearly from the second end 120 to the first end 110 (i.e., the first sampling member 310 moves along the positive direction of the X-axis to extend), so as to hammer deep-sea rocks, minerals or other hard materials, thereby performing deep-sea sampling.

[0040] After the sliding shaft 320 moves to one end of the second linear groove 1311b close to the first end 110 of the transmission member 100, similarly, the sliding shaft 320 can be moved from one end of the second arc-shaped groove 1312b close to the first end 110 of the transmission member 100 to one end of the second arc-shaped groove 1312b close to the second end 120 of the transmission member 100 under the action of the transmission member 100, and when the sliding shaft 320 moves in the second arc-shaped groove 1312b, the first sampling member 310 also moves linearly from the first end 110 to the second end 120 (that is, the first sampling member 310 moves along the negative direction of the X-axis for recovery) and compresses the elastic member 340. When the sliding shaft 320 moves to the end of the first linear groove 1311a close to the second end 120 of the transmission member 100, the elastic member 340 recovers and drives the sliding shaft 320 to move from the end of the first linear groove 1311a close to the second end 120 of the transmission member 100 to the end of the first linear groove 1311a close to the first end 110 of the transmission member 100 (i.e., the elastic member 340 drives the sliding shaft 320 to move in the first linear groove 1311a along the positive direction of the X-axis), thereby driving the first sampling member 310 to move linearly from the second end 120 to the first end 110 (i.e., the first sampling member 310 moves along the positive direction of the X-axis to extend), so as to hammer deep-sea rocks, minerals or other hard materials for deep-sea sampling.

[0041] After the sliding shaft 320 moves to the end of the first linear groove 1311a close to the first end 110 of the transmission member 100, it will enter the first arc groove 1312a under the transmission action of the transmission member 100 and repeat the above movement trajectory. In other words, the first sampling member 310 can complete two hammerings when the transmission member 100 rotates one circle.

[0042] It is understandable that the first sampling member 310 can be hammered multiple times by rotating the transmission member 100. The hammering frequency of the first sampling member 310 can be adjusted by adjusting the rotation speed of the transmission member 100, and the faster the rotation speed of the transmission member 100, the faster the hammering frequency of the first sampling member 310.

[0043] It is understandable that the slide groove 131 may also include two symmetrical and intersecting spiral grooves extending along the length direction of the transmission member 100, and both ends of the two spiral grooves are connected, so that the transmission member 100 can linearly drive the first sampling member 310 to reciprocate along the length direction of the transmission member, which will not be described in detail here. Compared with this structural setting, in the embodiment of the present application, by setting a linear groove, an arc groove and an elastic member 340, the hammering effect can be further achieved, thereby increasing the force on the deep-sea rocks, minerals or other materials to be collected, so as to further improve the sampling efficiency.

[0044] Optionally, in some embodiments, see Figure 4 and Figure 6 The sampling device also includes a fixing member 400 arranged on the outer peripheral side of the transmission member 100, the fixing member 400 extends along the axial direction of the transmission member 100, and a cavity 410 is opened in the fixing member 400. The first sampling member 310 is movably arranged in the cavity 410, and the elastic member 340 is also arranged in the cavity 410, and one end of the elastic member 340 away from the first sampling member 310 is fixedly connected to the fixing member 400.

[0045] Optionally, one end of the fixing member 400 close to the first end 110 of the transmission member 100 may be flush with the first end 110 of the transmission member 100. It is understood that "the first sampling member 310 extends" in the embodiment of the present application means that the first sampling member 310 can extend out of the fixing member 400 to perform sampling work, and "the first sampling member 310 is recovered" means that the first sampling member 310 can be recovered into the cavity 410 of the fixing member 400.

[0046] Alternatively, see Figure 6 The fixing member 400 is formed with a guide groove 411 in the cavity 410 , and the first sampling member 310 is slidably disposed in the guide groove 411 , so that the guide groove 411 can guide the first sampling member 310 to move.

[0047] Of course, other guide parts may be provided to guide the movement of the first sampling member 310, and no specific limitation is given here. For example, a guide rail is provided on the first sampling member 310, and a groove matching the guide rail is provided on the fixing member 400 to guide the movement of the first sampling member 310.

[0048] Optionally, in some embodiments, the sampling device further includes a pressing piece 330, the first sampling piece 310 is connected to the elastic piece 340 via the pressing piece 330, the pressing piece 330 is also disposed in the cavity 410, the fixing piece 400 is provided with an opening 420 connected to the cavity 410, the sliding shaft 320 at least partially extends from the opening 420 to be embedded in the sliding groove 131, and the sliding shaft 320 can move along the extension direction of the opening 420.

[0049] Optionally, the first sampling member 310, the sliding shaft 320, and the pressing member 330 can be integrally formed. Of course, the sliding shaft 320 and the pressing member 330 can also be fixedly connected to the first sampling member 310 by welding or other connection methods, which is not specifically limited here.

[0050] For example, see Figure 4 and Figure 6 , two elastic members 340 are provided, which is beneficial to improve the stability of the pressing member 330 and the first sampling member 310 during movement. Optionally, the pressing member 330 is provided on the side of the first sampling member 310 away from the sliding shaft 320, and the pressing member 330 includes a first pressing head 331 and a second pressing head 332 connected to each other. One end of one of the elastic members 340 is connected to the first pressing head 331, and the other end is connected to the bottom of the fixing member 400. One end of the other elastic member 340 is connected to the second pressing head 332, and the other end is connected to the bottom of the fixing member 400. Optionally, the elastic member 340 is a spring.

[0051] Optionally, the opening 420 on the fixing member 400 is parallel to the linear groove on the transmission member 100, and both ends of the opening 420 can be flush with both ends of the linear groove, or extend beyond both ends of the linear groove to avoid interfering with the movement of the sliding shaft 320 in the linear groove and the arc groove.

[0052] Alternatively, see Figure 7 The first sampling member 310 includes two first side walls 311 and two second side walls 312. Optionally, the guide groove 411 includes two third side walls, which are respectively in contact with the two first side walls 311 of the first sampling member 310 (see Figure 6 and Figure 7). The maximum width between the two first side walls 311 arranged opposite to each other is greater than the width of the opening 420, so as to prevent the first sampling piece 310 from escaping from the opening 420. Optionally, the first side wall 311 includes two connected sub-side walls 3111, and the two sub-side walls 3111 form an outwardly convex angle a, and the angle a can be an acute angle, a right angle, or an obtuse angle. Of course, the first side wall 311 can also adopt other structures, so that the maximum width between the two first side walls 311 can be greater than the width of the opening 420, so as to prevent the first sampling piece 310 from escaping from the opening 420, and no specific limitation is made here.

[0053] Alternatively, see Figure 6 and Figure 7 The sliding shaft 320 is disposed on the second side wall 312 on the side close to the opening 420, and the pressing member 330 is disposed on the second side wall 312 on the side away from the opening 420. Optionally, the second side wall 312 on the side close to the opening 420 of the first sampling member 310 is flush with the outer surface of the fixing member 400, that is, the second side wall 312 of the first sampling member 310 on which the sliding shaft 320 is disposed is flush with the opening 420 of the fixing member 400, and the sliding shaft 320 is entirely located outside the opening 420.

[0054] Optionally, in some embodiments, see Figure 7 , a plurality of protrusions 3131 are provided on the working surface 313 of the first sampling member 310 to enhance the hammering effect of the first sampling member 310. Optionally, the working surface 313 of the first sampling member 310 is the end surface of the extended end of the first sampling member 310. Optionally, the plurality of protrusions 3131 are arranged in an array on the working surface 313 of the first sampling member 310. Of course, the specific number and specific arrangement of the protrusions 3131 can be set according to actual needs, and no specific limitation is made here.

[0055] Optionally, in some embodiments, see Figure 4 The sampling device further includes a second sampling member 500 , which is fixedly connected to the first end 110 of the transmission member 100 , and the second sampling member 500 is arranged to protrude from the transmission member 100 along the axial direction of the transmission member 100 .

[0056] It is understandable that the second sampling member 500 is fixedly connected to the transmission member 100. When the transmission member 100 rotates, the second sampling member 500 also rotates synchronously around the axis of the transmission member 100 to perform sampling. The rotation speed of the second sampling member 500 can be adjusted by adjusting the rotation speed of the transmission member 100, and the faster the rotation speed of the transmission member 100, the faster the rotation speed of the second sampling member 500. Optionally, the second sampling member 500 can be a shift fork.

[0057] Optionally, in some embodiments, the second sampling member 500 is provided in plurality, and the plurality of second sampling members 500 are arranged at the first end 110 of the transmission member 100 along the circumference of the transmission member 100. Figure 4 The number of the second sampling members 500 is three, and the three second sampling members 500 are arranged on the end surface of the first end 110 of the transmission member 100 along the circumferential direction of the transmission member 100 .

[0058] Optionally, in some embodiments, the first end 110 of the transmission member 100 is open to collect samples. It is understandable that when the transmission member 100 drives the first sampling member 310 and the second sampling member 500 to perform sampling operations, the crushed samples can directly enter the transmission member 100, thereby realizing sample collection. The transmission member 100 in the embodiment of the present application can also be used to collect samples while performing transmission, and the structure is compact, and the collected samples do not affect the transmission of the transmission member 100.

[0059] For example, see Figure 3 and Figure 4 The transmission member 100 includes a cup-shaped barrel cam 130 and a flange 140 connected to each other. Optionally, a slide groove 131 is arranged on the outer curved surface of the cup-shaped barrel cam 130. The flange 140 is provided with a plurality of bolts 141 along the circumferential direction to be fixedly connected with the cup-shaped barrel cam 130. The end of the cup-shaped barrel cam 130 away from the flange 140 is the first end 110 of the transmission member 100, and the end of the flange 140 away from the cup-shaped barrel cam 130 is the second end 120 of the transmission member 100. Optionally, the end of the cup-shaped barrel cam 130 away from the flange (i.e., the first end 110 of the transmission member 100) is openly arranged to collect samples of deep-sea rocks, minerals, etc. collected.

[0060] Optionally, in some embodiments, the sampling device further comprises a driving member 200, and the driving member 200 is connected to the transmission member 100 to drive the transmission member 100 to rotate. Optionally, the driving member 200 is a driving motor, and the driving shaft of the driving motor is connected to the transmission member 100 through a coupling shaft 210 (see Figure 1 ). Optionally, the driving shaft of the driving motor is connected to the second end 120 of the transmission member 100 through the connecting shaft 210, that is, one end of the connecting shaft 210 is connected to the driving shaft of the driving motor, and the other end of the connecting shaft 210 is connected to the flange 140. Figure 1 The end of the driving motor away from the second end 120 of the transmission member 100 is provided with an interface end 220, and the interface end 220 is provided with a power supply end 221 and a control end 222.
