Description

Technical Field

[0001] The invention relates to the field of marine science and technology, in particular to a flexible capture device for marine biological research. Background Art

[0002] With the continuous development of science and technology and the growing demand for marine biological research, in order to facilitate the accurate capture of target organisms in marine biological research and ensure the quality and integrity of research samples, it is necessary to capture target organisms in the marine environment through a flexible capture device. The flexible capture device can adapt to various complex marine environments and minimize the damage to marine organisms. Therefore, it is necessary to design a more gentle, efficient and adaptable flexible capture device for marine biological research.

[0003] The invention patent with the Chinese patent announcement number CN111713466B is a water body organism capture device, which includes a frame assembly, a capture assembly, the capture assembly is mounted on the frame assembly, and a driving device, the driving device is mounted on the frame assembly and is used to drive the capture assembly to move. The invention has a capture folding structure and a negative pressure structure that cooperate with each other, which can make the water body organism capture device capture faster and ensure that soft biological samples are not damaged;

[0004] However, when the capture folding structure is in the preparatory capture state, the capture folding structure is in an overall contracted state. Since the capture folding structure is a long structure, the two inner ends of the capture folding structure fold inward and converge in its contracted state, and will gradually form two relative triangular shapes. When the capture operation begins, the two inner ends of the capture folding structure will unfold, and its two triangles will gradually form a straight line. However, the negative pressure generated by the negative pressure structure will drive the soft organisms in the water to quickly rush into the capture folding structure. When the capture folding structure gradually unfolds, its two triangles will hinder the soft organisms in the water and even cause damage to the soft organisms in the water. Moreover, it is only captured in one direction of the capture folding structure, and it is impossible to capture in multiple directions in the water, resulting in low capture efficiency. Secondly, when the organism needs to exit the capture folding structure, the capture folding structure and the negative pressure structure need to be contracted by the moving parts first. Due to the negative pressure, the biological sample is quickly discharged from the inside of the capture folding structure. Due to the limitation of the gradual expansion of the two triangles, there are safety hazards when the biological sample is discharged, and there is a certain degree of damage to the organism.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 9 , the present invention provides a technical solution:

[0036] Embodiment 1: Figure 1-Figure 6As shown, a flexible capture device for marine biological research includes a capture seat 1, an opening and closing component 2 and a discharging component 3. Two capture rings 11 are arranged below the capture seat 1. The capture rings 11 are hollow circular structures. The capture ring 11 located at the top is fixedly connected below the capture seat 1. A capture connecting frame 12 in a circular array is installed between the two capture rings 11. A capture net 13 is arranged inside the two capture rings 11. A suction rod 14 is installed on one side below the capture seat 1. Fixed air bags in a linear array are installed on the outer wall of the suction rod 14 to prevent the organism from causing direct damage to the suction rod 14. A suction hole 15 for attracting biological element substances is opened on the outer side of the suction rod 14. A device for regularly adding biological element substances is arranged inside the suction rod 14. The capture seat 1 is provided with a detection sensor 16 for detecting the activity of the organism, and the detection sensor 16 is an image sensor, which can obtain the image of the capture area in real time and directly observe the activity state of the organism. The capture seat 1 is provided with a suction hole 15, and the elements of the organism attracted therein and the detection sensor 16 cooperate with each other to better assist the capture operation and improve the success rate of capture. The opening and closing component 2 is provided on the capture seat 1, and is used to drive the capture net 13 to open and close. The opening and closing component 2 includes an air pump 21, wherein the detection sensor 16 and the air pump 21 are connected through an external terminal signal. A waterproof cover 22 is installed on the top of the capture seat 1, and the air pump 21 is electrically The machine base is installed on the top of the waterproof cover 22, and a driving column 23 is installed in the middle of the top surface of the capture seat 1. A first air hole 24 is opened inside the driving column 23, and the air outlet end of the air pump 21 is connected inside the first air hole 24. A first electrical valve 25 connected to the first air hole 24 is installed in the middle of the inner cavity of the driving column 23, and a first output pipe 26 in a ring array is installed on the outer side of the first electrical valve 25. A fixing sleeve 27 in a ring array is installed on the side of the capture seat 1 away from the driving column 23. One end of the first output pipe 26 away from the driving column 23 is fixedly connected inside the fixing sleeve 27. The fixing sleeve 27 is an arc-shaped structure as a whole. One end of the fixing sleeve 27 away from the first output pipe 26 is slidably connected to a piston rod 28, and a linkage wheel 29 is rotatably connected to the middle of the top of the capture seat 1 The top of the capture seat 1 is rotatably connected to a transmission wheel 210 that meshes with the linkage wheel 29, and the linkage wheel 29 is fixedly connected to a transmission plate 211 on the side away from the center axis of the capture seat 1 by bolts. The transmission plate 211 and the piston rod 28 are fixedly connected. An arc plate 212 that is coaxially fixedly connected to the transmission wheel 210 is rotatably connected between the two capture rings 11. The outer side of the arc plate 212 is set to a flexible material. The capture net 13 is set between the spaced arc plates 212. An arc groove 213 is opened on the top of the capture seat 1. An arc rod 214 is installed inside the arc groove 213. The end of the arc rod 214 close to the transmission plate 211 slides through the inner side of the piston rod 28, and a curved spring 215 is sleeved on the outer side of the arc rod 214.

[0037] First, a substance that attracts biological elements is placed in the suction hole 15 on the suction rod 14. When the biological body passes through the capture net 13 and enters the two capture rings 11, the detection sensor 16 detects the biological body's activities to help determine the capture time. Then, the air pump 21 is started through a signal. The gas generated by the air pump 21 enters the driving column 23 through the first air hole 24, and then is distributed to each first output pipe 26 through the first electrical valve 25. The gas pushes the piston rod 28 to slide in the fixed sleeve 27, and the piston rod 28 drives the transmission plate 211 to move, thereby causing the linkage wheel 2 9 rotates counterclockwise, the linkage wheel 29 drives the transmission wheel 210 meshing therewith to rotate clockwise, and the transmission wheel 210 drives the arc plate 212 to rotate clockwise. At this time, the rotation of multiple arc plates 212 will drive the capture net 13 to perform a closing operation. At the same time, multiple arc plates 212 form a circular enclosure in the capture ring 11 to prevent the organism from escaping. When it is necessary to unfold the arc plate 212, the gas inside the first output pipe 26 is driven to be evacuated through the air pump 21. At this time, the transmission plate 211 and the piston rod 28 return to their original positions under the elastic force of the curved spring 215.

[0038] like Figure 3 As shown, by providing an arc rod 214 and a curved spring 215, the elasticity of the curved spring 215 is released, so that the transmission plate 211 drives the piston rod 28 to enter the interior of the fixed sleeve 27, so as to completely discharge the air inside the fixed sleeve 27, so as to restore the arc plate 212 to the best position to unfold, and prevent the air inside the fixed sleeve 27 from being insufficiently discharged.

[0039] The flexible material design of the curved plate can reduce possible damage to marine life during the opening and closing process, and play a certain protective role for marine life.

[0040] The present invention can present the capture net 13 on the capture ring 11 in a multi-directionally unfolded form, and with the help of the substance that attracts the elements of the organism placed in the attraction hole 15, the organism can be trapped in it in advance. When capturing the organism, a complete structural system can be formed. At the same time, in coordination with the opening and closing component 2, it effectively reduces the obstruction and damage that may be caused to the soft organisms in the water, and effectively protects the integrity of the organisms. This design is no longer limited to capture in a single direction, but greatly expands the opportunity and scope of capture, and significantly improves the overall capture effect.

[0041] like Figure 2 As shown, there are six groups of capture nets 13, which are arranged in a circular array between two capture rings 11. Each group of capture nets 13 is provided with three feed ports, and the feed ports are cone-shaped structures.

[0042] Each group of capture nets is provided with three feed ports, and the feed ports are of a cone-shaped structure, which facilitates the organisms to enter the capture net more easily, improves the capture efficiency, makes the capture process more stable, and reduces the possibility of the organisms escaping.

[0043] like Figure 6 As shown, a first elastic bag 131 in a rectangular array is installed on the side of the capture net 13 away from the central axis of the capture ring 11, and the first elastic bag 131 is fixedly connected between the spaced arc plates 212, and a second elastic bag 132 is installed on the side of the capture net 13 close to the central axis of the capture ring 11, and the second elastic bag 132 is fixedly connected to the side wall of the arc plate 212 on the side away from the capture net 13.

[0044] When the capture net 13 is opening and closing, the first elastic bag 131 and the second elastic bag 132 will undergo elastic deformation, which can help the capture net 13 to fold and prevent the organism from jumping out, and can help the capture net 13 to unfold an open structure, thereby increasing the contact area between the capture net 13 and the marine life and improving the capture efficiency; at the same time, through the elastic action of the first elastic bag 131 and the second elastic bag 132, the damage to the marine life is reduced and the integrity of the organism is protected. Example

[0045] As an embodiment of the present invention, Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the discharge assembly 3 is arranged on the capture ring 11 located below, and is used for safely discharging the organism. The discharge assembly 3 includes a second electric valve 31 installed at the bottom of the inner cavity of the driving column 23, the air inlet end of the second electric valve 31 is connected to the first air hole 24, and a second output pipe 32 in a ring array is installed on the outer side of the second electric valve 31. A first air bag folding structure 33 is installed below the capture seat 1, and one end of the second output pipe 32 passes through the bottom of the capture seat 1 and is connected to the inside of the first air bag folding structure 33. The capture ring located below A fixing seat 34 is installed on the right side of 11, a threaded ring 35 is arranged below the capture ring 11 below, a rotating block 36 is installed on the right side of the threaded ring 35, the rotating block 36 is rotatably connected below the fixing seat 34, the internal thread of the threaded ring 35 is connected to a fish storage box 37, a notch ring is provided at the bottom of the capture ring 11 below, the fish storage box 37 is tightly attached to the inner side of the notch ring, a driving ring 38 is installed on the outer side of the fish storage box 37, a driving rod in a ring array is installed on the outer side of the driving ring 38, and a fishing net assembly 39 is arranged on the top of the fish storage box 37.

[0046] When it is necessary to discharge the material, the second electrical valve 31 is opened, and the high-pressure gas enters the second electrical valve 31 through the first air hole 24, and then enters the first airbag folding structure 33 through the second output pipe 32 to expand it. After the first airbag folding structure 33 expands, it pushes the organism to move along the inside of the fish storage box 37. At this time, the organism is retained on the fishing net assembly 39. When it is necessary to discharge the organism safely, the operator drives the driving rod to drive the driving ring 38 to rotate, and then the fish storage box 37 moves downward during the rotation process. At this time, the fish storage box 37 is separated from the notch ring, and then the operator drives the threaded ring 35 and the rotating block 36 to rotate along the fixed seat 34, so that the fishing net assembly 39 can be safely taken out. The present invention allows the organism to stay on the fishing net assembly 39 by gradually expanding the first airbag folding structure 33, reducing possible damage to it and ensuring the safety of the organism.

[0047] It is worth noting that the fish storage box 37 is a conical structure, and a through hole is opened on the conical structure. The through hole is mainly used when the first airbag folding structure 33 gradually expands. The water inside the capture ring 11 will be discharged at the bottom of the through hole, while the organisms are blocked due to their large size and cannot pass through the through hole, so they are safely retained in the fish storage box 37.

[0048] like Figure 7 and Figure 8 As shown, the fishing net assembly 39 includes a fishing net yarn 391, a circular rope 392 is installed on the outside of the fishing net yarn 391, and shock-absorbing ropes 393 in a circular array are installed on the outside of the circular rope 392. A disassembly ring 394 is installed on the side of the shock-absorbing rope 393 away from the fishing net yarn 391, and the disassembly ring 394 is arranged above the fish storage box 37.

[0049] By setting the fishing net yarn 391, the organism can be gently wrapped to reduce the damage to it; the annular rope 392 enhances the structural stability of the fishing net yarn, making it less likely to be deformed and damaged during operation; by setting the shock-absorbing rope 393, the shock-absorbing rope 393 can prevent the organism from contacting the fish storage box 37, preventing the organism from directly causing direct damage to the fish storage box 37. The shock-absorbing rope 393 can play a buffering and shock-absorbing role during operation, reduce the impact on the organism, and further ensure the safety of the organism.

[0050] like Figure 8 and Fig. 9 As shown, a limiting plate 395 in a ring array is installed on the outer side of the disassembly ring 394, and a first limiting groove 371 is opened on the top surface of the fish storage box 37. The limiting plates 395 are tightly attached to the inside of the first limiting groove 371.

[0051] By providing the limiting plate 395 and the first limiting groove 371, the firmness of the connection between the fishing net assembly 39 and the fish storage box 37 under normal conditions is ensured. At the same time, when disassembly is required, it is only necessary to remove the limiting plate 395 from the first limiting groove 371, which is convenient and quick to operate.

[0052] The top of the fish storage box 37 is rotatably connected to a control ring 311, and a second limiting groove 372 communicating with the first limiting groove 371 is provided on the top of the fish storage box 37. A control seat 312 slidably connected to the inner side of the second limiting groove 372 is installed on the inner side of the control ring 311, and a telescopic spring rod 313 is installed on the bottom wall of the first limiting groove 371. A top plate is installed on the top of the telescopic spring rod 313, and the top plate is tightly attached to the bottom of the disassembly ring 394.

[0053] By rotating the control ring 311, the control seat 312 can be driven to slide in the second limit groove 372, so as to control the position of the disassembly ring 394. When the fishing net assembly needs to be fixed, the control seat 312 is slid to a position corresponding to the disassembly ring 394 so that it can clamp the disassembly ring 394 to prevent it from loosening. When the fishing net assembly needs to be disassembled, the control seat is slid to other positions, and then the elastic potential energy of the telescopic spring rod 313 is released to drive the top plate to be pushed out against the disassembly ring 394, so that the fishing net assembly 39 can be easily taken out. The present invention can ensure that the fishing net assembly 39 is firmly locked when it needs to be fixed to avoid accidental loosening during operation. When it needs to be disassembled, it can automatically pop up to facilitate the operator to quickly take it out.

[0054] like Figure 4 and Figure 6 As shown, the bottom wall of the inner cavity of the driving column 23 is installed with a connecting delivery pipe 321 connected to the air outlet end of the second electric valve 31, the arc plate 212 is a micro-arc-shaped structure, and the inner side surface of the arc plate 212 is installed with a second airbag folding structure 322, and the other end of the connecting delivery pipe 321 passes through the capture seat 1 and is connected to the inside of the second airbag folding structure 322.

[0055] When the opening and closing component 2 drives the arc plate 212 to close, and then the first airbag folding structure 33 gradually expands, the high-pressure gas enters the second electrical valve through the first air hole, and then enters the second airbag folding structure 322 through the second output pipe. Since the multiple arc plates 212 are closed in a circular ring shape to surround the organism, when the internal gas of the second airbag folding structure 322 on the arc plate 212 swells, the second airbag folding structure 322 and the first airbag folding structure 33 are in contact, which prevents the organism from rushing around inside the capture ring 11 and causing the organism to directly collide with the arc plate 212. Through the cooperation of the first airbag folding structure 33 and the second airbag folding structure 322, the organism can be further discharged safely.

[0056] Working principle: This is a flexible capture device for marine biological research. First, a substance that attracts biological elements is placed in the suction hole 15 of the suction rod 14. When the biological body enters the capture ring 11, the detection sensor 16 detects its activity to determine the capture time. Then the air pump 21 is started, and the gas enters the driving column 23 through the first air hole 24, and is distributed to each first output pipe 26 through the first electrical valve 25, pushing the piston rod 28 and the transmission plate 211 to move, so that the linkage wheel 29 rotates counterclockwise, driving the transmission wheel 210 to rotate clockwise, from The arc plate 212 rotates clockwise to close the capture net and surround it in a circular shape to prevent the organism from escaping. When unfolding, the air pump 21 extracts the gas in the first output pipe 26, and uses the curved spring 215 to restore the transmission plate 211 and the like to their original positions. When discharging, the second electrical valve 31 is opened, the first electrical valve 25 is closed, and high-pressure gas enters the second output pipe 32 to expand the first airbag folding structure 33 and push the organism to the fishing net assembly 39. The driving rod drives the driving ring 38 to rotate, so that the fish storage box 37 moves down and rotates through the threaded ring 35 and the rotating block 36. The fishing net assembly 39 can be safely taken out; the first airbag folding structure 33 can make the organism stay and reduce damage to ensure safety. By setting the limit plate 395 and the like, the connection between the fishing net assembly 39 and the fish storage box 37 is firmly ensured and the disassembly is convenient. The position of the disassembly ring can be controlled by rotating the control ring 311 to achieve the fixing and disassembly of the fishing net assembly 39. When the opening and closing assembly 2 drives the arc plate 212 to close, the first airbag folding structure 33 gradually expands, and the high-pressure gas enters the second electric valve through the first air hole, and then enters the second output pipe through the second output pipe. Inside the second airbag folding structure 322, since the multiple arc plates 212 are closed to form a circular ring surrounding the organism, when the gas inside the second airbag folding structure 322 on the arc plate 212 swells, the second airbag folding structure 322 and the first airbag folding structure 33 are in contact, which prevents the organism from rushing around inside the capture ring 11 and causing the organism to directly collide with the arc plate 212. Through the mutual cooperation of the first airbag folding structure 33 and the second airbag folding structure 322, the organism can be further discharged safely.
