Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea sampling, and in particular to a deep-sea macroorganism heat-insulating and pressure-insulating sampler. Background Art

[0002] Due to the rapid development of marine technology, humans have discovered that the deep sea contains huge treasures. Exploring marine biological resources helps to explore new organisms and life mechanisms. Systematic research on biological resources and biodiversity of deep-sea ecosystems has important scientific significance for humans to reveal the origin of life and the unique environmental adaptation mechanism of deep-sea organisms.

[0003] Due to the higher pressure and lower temperature in the deep sea, when collecting deep-sea organisms, it is necessary to maintain the environmental pressure and temperature during the recovery period to ensure that the organisms can survive normally and do not die. This means that conventional capture methods such as trawls and grabs cannot be used to capture deep-sea organisms, and specific samplers are needed to capture them.

[0004] Application No. CN202010057234.5 discloses a full-sea-depth macrobiological sampler with pressure-maintaining storage and transfer functions, including a pressure-maintaining barrel, a pressure compensation device, a whisker mouth mechanism, a bait tube and an outlet sealing mechanism; an inlet sealing mechanism is installed at the inlet of the pressure-maintaining barrel, and the whisker mouth mechanism is installed in the inner cavity of the pressure-maintaining barrel; the whisker mouth mechanism includes a whisker with a conical structure that is small at the top and large at the bottom, a screw, an active bevel gear, a driven bevel gear and a rocker, the whisker is connected to the lower end of the screw, the upper end of the screw is connected to the driven bevel gear, the rocker is arranged on the side wall of the pressure-maintaining barrel along the radial direction of the pressure-maintaining barrel, and the inner end of the rocker is provided with An active bevel gear meshing with a driven bevel gear; a pressure compensation device is connected to a pressure-maintaining barrel through a high-pressure pipe; a bait tube is connected to an inner cavity of the pressure-maintaining barrel through a high-pressure pipe, and a switch valve is provided on the high-pressure pipe; the outlet sealing mechanism is installed at the outlet of the pressure-maintaining barrel. The invention has a simple structure and is easy to operate, and can realize pressure-maintaining sampling of macro-organisms in a full-sea depth environment. However, since the pressure-maintaining barrel and the bait tube are directly connected and fixed, the entire device needs to be moved when automatically capturing organisms, and the inlet sealing mechanism needs to be opened manually, resulting in low capture efficiency.

[0020] Beneficial effects of the present invention:

[0021] (1) The deep-sea macro-biological heat preservation and pressure preservation sampler proposed in the present invention takes samples through a sampling device, and the sampling tube and the bait tube are fixed by magnetic attraction. After the sampling tube takes samples, the sampling tube is driven by a manipulator to move the operating rod to move the sampling device into the pressure preservation barrel and the heat preservation barrel to separate the sampling tube. When capturing marine life, only the sampling tube and the bait tube need to be moved, which has higher capture efficiency and success rate. Secondly, the heat preservation barrel can also maintain the temperature of the marine environment for the entire device, so that the organisms can survive better. Finally, the sampling tube and the bait tube are separated, and the sampling tube is separated to the pressure preservation barrel for heat preservation and pressure preservation, which can reduce the volume occupied by the pressure preservation barrel.

[0022] (2) The deep-sea macro-biological heat-insulating and pressure-maintaining sampler proposed in the present invention is provided with a closing device on the end cover of the pressure-maintaining barrel. When the sampling device enters the interior from the opening on the end cover of the pressure-maintaining barrel, the sampling device pushes the valve cover of the closing device to rotate. After the bait tube and the sampling tube are separated, the valve cover will rebound due to the elastic force of the first elastic member, thereby automatically closing the pressure-maintaining barrel. The structure is simpler. During transfer, the protruding shaft of the valve cover can be rotated by a wrench to make the transfer of marine organisms smoother.

[0023] (3) The deep-sea macro-biological heat-insulating and pressure-insulating sampler proposed in the present invention separates the sampling tube and the bait tube through a snap-fit ​​device. The sampling device moves to the inside of the pressure-insulating barrel and compresses the second elastic member. When the sampling tube and the bait tube are fixed at the position of the second elastic member, the second elastic member rebounds and clamps the sampling tube to separate the sampling tube and the bait tube. The snap-fit ​​device can better separate the sampling tube and the bait tube, and it is more convenient to store them in the pressure-insulating barrel and the heat-insulating barrel after capturing the organisms.

[0024] (4) The deep-sea macrobiological heat-keeping and pressure-keeping sampler proposed in the present invention is configured by separately setting a pressure-keeping barrel, a heat-keeping barrel and an energy storage device. The energy storage device maintains the internal pressure of the pressure-keeping barrel. By placing the energy accumulator in the pressure-keeping barrel, and the pressure-keeping barrel in the heat-keeping barrel, the structure of the device can be greatly simplified and the compactness of the device can be improved.

[0033] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

[0034] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0035] Please refer to Figure 1-Figure 7 The present invention proposes a deep-sea macrobiological heat preservation and pressure preservation sampler comprising a pressure preservation barrel 2, a heat preservation barrel 1 and a sampling device 3, wherein:

[0036] The sampling device 3 includes a sampling tube 3-2 and a bait tube 3-6. An operating rod 3-7 is fixed to one side of the bait tube 3-6, and a fishing net 3-5 is fixed to the other side of the bait tube 3-6. A bait cavity is provided inside the bait tube 3-6, and the fishing net 3-5 seals the bait in the bait cavity. A conical net 3-1 is fixed to one end of the sampling tube 3-2, and the other end is fitted with the fishing net 3-5 side of the bait tube 3-6. An iron block 3-3 is embedded on the inner wall of the other end of the sampling tube 3-2, and a magnet 3-4 is embedded on the inner wall of the bait tube 3-6 near the fishing net 3-5. The sampling tube 3-2 and the bait tube 3-6 are fixed by adsorption through the iron block 3-3 and the magnet 3-4 respectively.

[0037] A pressure-maintaining chamber is provided inside the pressure-maintaining barrel 2. The sampling device 3 samples the biological sample into the sampling tube 3-2, and the manipulator drives the operating rod 3-7 to send the sampling tube 3-2 into the pressure-maintaining barrel 2 to separate the sampling tube 3-2 so that the sampling tube 3-2 remains in the pressure-maintaining barrel 2.

[0038] The insulation barrel 1 has an insulation cavity inside, an upper cover 6 is provided on the top of the insulation barrel 1, the pressure-maintaining barrel 2 is fixed in the insulation cavity, and a spiral groove is provided on the inner wall of the insulation barrel 1 for circulating low-temperature circulating water to maintain the temperature.

[0039] In this embodiment:

[0040] The pressure-maintaining barrel 2 is used to provide a pressure-maintaining bearing structure for the organisms;

[0041] The upper cover 6 is used to close and disconnect the heat preservation barrel 1;

[0042] The heat preservation barrel 1 is used to provide a heat-insulating bearing structure for the organisms;

[0043] The sampling tube 3-2 is used to provide a containment structure for marine organisms;

[0044] The operating rods 3-7 are used to provide a clamping structure for the manipulator;

[0045] The bait tubes 3-6 are used to provide a structure for storing bait;

[0046] The conical net 3-1 is used to prevent organisms from escaping from the sampling tube 3-2;

[0047] The fishing net 3-5 is used to seal the bait for capturing organisms into the bait tube 3-6;

[0048] The magnet 3-4 and the iron block 3-3 are used to adsorb and connect the operating rod 3-7 and the sampling tube 3-2;

[0049] Specifically, the spiral groove can circulate low-temperature circulating water, and the cooled liquid can keep the insulation barrel 1 warm. Under the guidance of the bait, the marine organisms enter the sampling tube 3-2 through the conical net 3-1. After entering the conical net 3-1, it is difficult for the organisms to escape from the sampling tube 3-2 from the conical net 3-1. Then the manipulator drives the operating rod 3-7 to place the sampling tube 3-2 into the pressure-keeping chamber of the pressure-keeping barrel 2, and the sampling tube 3-2 is kept warm and pressurized by the pressure-keeping barrel 2 and the insulation barrel 1. The organisms are captured by the sampling tube 3-2 and the bait tube 3-6. The organisms will not be affected by other devices, and the success rate is higher. Secondly, during capture, the efficiency is higher, and the sampling device 3 only needs to be moved by the operating rod 3-7.

[0050] Furthermore, it also includes an energy storage device 8, which includes a pressure-maintaining tube 8-3 fixed inside the pressure-maintaining chamber, a piston 8-4 is provided inside the pressure-maintaining tube 8-3, the piston 8-4 isolates the inside of the pressure-maintaining tube 8-3 into a gas chamber 8-2 and a liquid chamber 8-5, a liquid inlet 8-6 is provided at the top of the pressure-maintaining tube 8-3, and an air inlet 8-1 is provided at the bottom of the pressure-maintaining tube 8-3, the liquid inlet 8-6 and the air inlet 8-1 are connected to the liquid chamber 8-5 and the gas chamber 8-2 respectively.

[0051] In this embodiment:

[0052] The liquid chamber 8-5 can store deep-sea liquid;

[0053] The gas chamber 8-2 can be used to store nitrogen;

[0054] The pressure-maintaining tube 8-3 can provide a bearing structure;

[0055] The piston 8-4 can adaptively adjust the pressure balance between the liquid chamber 8-5 and the gas chamber 8-2;

[0056] The liquid inlet 8-6 is used to connect the liquid to the liquid chamber 8-5;

[0057] The gas inlet 8-1 is used to introduce nitrogen into the gas chamber 8-2;

[0058] For details, please refer to the attached Figure 5, the piston 8-4 can slide inside the pressure-maintaining tube 8-3, and the piston 8-4 divides the space inside the pressure-maintaining tube 8-3 into a gas chamber 8-2 and a liquid chamber 8-5. A valve that opens when inflating can be provided on the air inlet 8-1, and the valve is manually closed after the air is inflated. The air inlet 8-1 is pre-filled with nitrogen to enter the gas chamber 8-2. At this time, the piston 8-4 is moved to the top of the pressure-maintaining tube 8-3 by the action of the air pressure, and the air inlet 8-1 is closed. Since the pressure-maintaining tube 8-3 is located in the pressure-maintaining chamber, the liquid inlet 8-6 of the pressure-maintaining tube 8-3 is connected to the pressure-maintaining chamber. When deep sea water enters the pressure-maintaining chamber, the sea water The water pressure is greater than the pre-charged nitrogen, and the seawater pressure will push the piston 8-4 downward, thereby compressing the nitrogen and increasing the nitrogen pressure until the nitrogen pressure is balanced with the pressure of the seawater environment. When the pressure-maintaining barrel 2 is recovered, if the pressure in the pressure-maintaining chamber drops, the pressure in the pressure-maintaining chamber will be lower than the nitrogen pressure. The nitrogen will push the piston 8-4 to move to maintain the pressure balance between the gas chamber 8-2 and the liquid inside the pressure-maintaining chamber, thereby maintaining the pressure to maintain the living environment of the organism. By placing the energy storage device 8 in the pressure-maintaining barrel, the structure can be simplified and the compactness can be improved.

[0059] Furthermore, an end cover 5 is fixed on the top of the pressure-maintaining barrel 2, and a closing device 7 is provided on one side of the bottom of the end cover 5. The closing device 7 includes a valve cover 7-1, and a rotating shaft 7-3 is provided on one side of the valve cover 7-1. The valve cover 7-1 is fixed on the rotating shaft 7-3. Both sides of the rotating shaft 7-3 are rotatably connected to the end cover 5. An extension shaft 7-4 is fixed at one end of the rotating shaft 7-3. The extension shaft 7-4 penetrates the pressure-maintaining barrel 2 and is rotatably connected to the pressure-maintaining barrel 2. The extension shaft 7-4 extends to the outside of the pressure-maintaining barrel 2. A bearing 7-5 is also provided on one side of the extension shaft 7-4. The bearing 7-5 is fixed on the pressure-maintaining barrel 2, and the extension shaft 7-4 is fixedly connected to the inner side of the bearing 7-5. The closing device 7 also includes at least two first elastic members 7-2. The two first elastic members 7-2 are respectively arranged on both sides of the rotating shaft 7-3. One end of the first elastic member 7-2 is fixedly connected to the pressure-maintaining barrel 2, and the other end is fixedly connected to the valve cover 7-1.

[0060] In this embodiment:

[0061] The end cover 5 is used to provide a mounting structure for the rotating shaft 7-3 and the pressure-maintaining barrel 2;

[0062] The valve cover 7-1 is used to open and close the pressure-maintaining barrel 2;

[0063] The rotating shaft 7-3 is used to provide a flip structure for the valve cover 7-1;

[0064] The extended shaft 7-4 is used to provide a rotating structure for manually opening the valve cover 7-1;

[0065] The bearing 7-5 can reduce the friction between the end cover 5 and the rotating shaft 7-3;

[0066] The first elastic member 7-2 can provide a reset structure for the valve body;

[0067] For details, please refer to the attached Figure 2 and attached Figure 6 The end cover 5 is fixed to the top of the pressure-maintaining barrel 2 by bolts. The opening of the end cover 5 is an upward-slanting cone. The valve body of the valve cover 7-1 matches the opening part. The valve cover 7-1 rotates and blocks the valve body and the opening of the end cover 5 to close. Since the opening is an upward-slanting cone, when the internal pressure increases, the contact force is greater and the sealing effect is better. The bearing 7-5 can reduce the friction during rotation. The extended shaft 7-4 can be rotated by a wrench. The valve cover 7-1 is rotated by rotating the extended shaft 7-4 with a wrench. When in use, after the sampling device 3 takes samples, the manipulator sends the bait tube 3-6 and the sampling tube 3-2 into the pressure-maintaining barrel 2 through the operating rod 3-7. The sampling tube 3-2 pushes the valve cover 7-1 to rotate, compressing the first elastic member 7-2, and the valve cover 7-1 is rotated to the storage On one side of the cavity, the locking device 4 then locks the sampling tube 3-2. When the bait tube 3-6 and the sampling tube 3-2 are separated, the valve cover 7-1 will rebound due to the elastic force of the first elastic member 7-2 to close the opening of the end cover 5. The rebound setting of the first elastic member 7-2 can make it more convenient to transport the sampling tube 3-2 to the inside of the pressure-maintaining cavity. Finally, when the organisms in the sampling tube 3-2 need to be transferred, since the valve cover 7-1 can only be opened to the inside, the extension shaft 7-4 is set and the extension shaft 7-4 is rotated to open the valve cover 7-1 from the side, which can better align the organisms with the culture kettle and transfer them into the culture kettle. The extension shaft 7-4 is rotated by a wrench to open the valve cover 7-1, so that the organisms can be smoothly transferred out from the opening of the end cover 5.

[0068] Furthermore, it also includes a locking device 4, which includes a support rod 4-1 and at least two second elastic members 4-2. The support rod 4-1 is fixed on the inner wall of the pressure-maintaining chamber, and the two second elastic members 4-2 are respectively located at both ends of the support rod 4-1. The support rod 4-1 passes through the second elastic member 4-2 and is movably connected to the second elastic member 4-2. The locking device 4 also includes a limiting rod 4-3, which is located on both sides of the support rod 4-1 and is fixedly connected to the support rod 4-1.

[0069] In this embodiment:

[0070] The second elastic member 4-2 is a torsion spring, and the second elastic member 4-2 is used to provide a fixing structure for the sampling tube 3-2;

[0071] The support rod 4-1 is used to provide a rotatable structure for the torsion spring;

[0072] The limiting rod 4-3 is used to provide a limiting structure for the second elastic member 4-2;

[0073] For details, please refer to the attached Figure 1 and attached Figure 2 When external force pushes the second elastic member 4-2, the second elastic member 4-2 will rotate clockwise. After the external force disappears, the second elastic member 4-2 will return to its original position. The limit rod 4-3 limits the second elastic follower needle sampling tube 3-2 from rotating upward. When the operating rod 3-7 drives the sampling tube 3-2 and the bait tube 3-6 into the pressure-maintaining chamber, it will just squeeze the second elastic member 4-2 to rotate clockwise. Since the diameters of the bait tube 3-6 and the sampling tube 3-2 are different, when the bait tube 3-6 reaches the position of the card and the device 4, the second elastic member 4-2 will move forward. The sampling tube 3-2 is reset to fix the sampling tube 3-2 at the bottom of the pressure-maintaining barrel 2. When the operating rod 3-7 drives the sampling tube 3-2 and the bait tube 3-6 to move outward, the second elastic member 4-2 cannot move upward with the sampling tube 3-2 due to the limitation of the limit rod 4-3. Therefore, when the pulling force of the operating rod 3-7 is greater than the magnetic attraction between the sampling tube 3-2 and the bait tube 3-6, the sampling tube 3-2 will remain in the pressure-maintaining chamber of the pressure-maintaining barrel 2. The sampling tube 3-2 and the bait tube 3-6 can be separated by the locking device 4, thereby retaining the organism in the pressure-maintaining chamber.

[0074] Furthermore, a visual window 10 for observing the state of the organism is fixed at the bottom of the pressure-maintaining barrel 2 .

[0075] In this embodiment:

[0076] The visual window 10 is used to provide a visual structure for observing organisms;

[0077] For details, please refer to the attached Figure 1 The visual window 10 can be used to observe the conditions of the organisms inside. The conditions of the organisms inside can be observed in real time through the visual window 10 .

[0078] Furthermore, a water inlet 11 is provided on one side of the bottom of the heat preservation barrel 1, and a water outlet 9 is provided on the other side of the bottom of the heat preservation barrel 1. The water inlet 11 and the water outlet 9 are connected to the spiral groove.

[0079] In this embodiment:

[0080] The water inlet 11 and the water outlet 9 are used to respectively introduce and discharge low-temperature circulating water into and out of the spiral groove;

[0081] Specifically, the insulation barrel 1 is connected to an external insulation system, which includes a water pump and a cold source cavity circuit. A refrigeration plate is provided inside the cold source cavity, and the refrigeration plate cools the water in the cold source cavity circuit. The cooled water is transported to the water inlet 11 through a circulating water pump, and then, after heat exchange through the spiral groove of the insulation barrel 1, the heated water flows into the cold source cavity through the water outlet 9 and is cooled again by the refrigeration plate.

[0082] In summary, in the specific implementation: the upper cover 6 of the heat preservation barrel 1 is opened, and after the sampling tube 3-2 collects organisms, the external manipulator drives the operating rod 3-7 and the bait tube 3-6 to drive the adsorbed sampling tube 3-2 to move, and the sampling tube 3-2 is inserted from the opening of the end cover 5 into the pressure-maintaining chamber of the pressure-maintaining barrel 2, and the sampling tube 3-2 first pushes the valve cover 7-1 to rotate and open, and the valve cover 7-1 rotates while the first elastic member 7-2 is compressed, and then the sampling tube 3-2 pushes the second elastic member 4-2 to rotate again, and the second elastic member 4-2 is compressed, and at the same time, external seawater enters the pressure-maintaining barrel 2, and the seawater pushes the piston 8-4 to compress the nitrogen, and when the connection between the sampling tube 3-2 and the bait tube 3-6 moves to the bottom of the second elastic member 4-2 When the bait tube 3-6 and the sampling tube 3-2 are fixed by the magnet 3-4 and the iron block 3-3, the sampling tube 3-2 will be separated from the bait tube 3-6 when the pulling force is greater than the suction force. When the bait tube 3-6 leaves the opening of the end cover 5, the valve cover 7-1 will rebound due to the elastic force of the first elastic member 7-2, thereby closing the opening of the end cover 5. Then the heat preservation barrel 1 and the pressure preservation barrel 2 keep the sampling tube 3-2 warm and pressurized. When transferring the organism, the opening of the end cover 5 is aligned with the culture kettle, and the valve cover 7-1 is opened by rotating the extended shaft 7-4 with a wrench, thereby allowing the organism to enter the culture kettle.

[0083] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
