However, the device lacks a complete docking method, especially when facing heavy deep-sea animal samplers, relying on manpower for docking is not only time-consuming and labor-intensive, but also inefficient. In addition, the design of the device makes it impossible to use it directly on board. The deep-sea animal sampler must be transported to the laboratory after the ship docks to complete the transfer of the animal, which undoubtedly prolongs the transfer time and reduces the survival rate of deep-sea animals.

[0028] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0029] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0031] like Figure 1-9As shown, an embodiment of the present invention provides a deep-sea animal ship-borne pressure-maintaining transfer device, including: a transfer chamber 1 and a transfer platform 2, the transfer chamber 1 is arranged on the transfer platform 2; the interior of the transfer chamber 1 is provided with a sealed cavity for accommodating and protecting deep-sea animals, and the outer surface of the transfer chamber 1 is provided with a docking interface 8 connected to the sealed cavity, which is used to dock with a deep-sea animal sampler or a laboratory animal culture device, so as to achieve the pressure-maintaining transfer of deep-sea animals. The transfer platform 2 includes a first platform 21, a driving unit and a second platform 22, the first platform 21 serves as the base of the entire transfer platform 2, the driving units are arranged on the first platform 21 from bottom to top, and the second platform 22 is arranged on the top of the driving unit, there are multiple driving units, which can be extended or shortened along their own axis; the transfer chamber 1 is arranged on the second platform 22, therefore, through the extension and retraction of the driving unit, the position of the transfer chamber 1 and the docking interface 8 thereon can be adjusted to achieve precise docking with different devices.

[0032] Through the coordinated work of multiple drive units, multiple degrees of freedom adjustment of the position of the transfer chamber 1 can be achieved, thereby ensuring fast and accurate docking with the deep-sea animal sampler or laboratory animal culture device.

[0033] Furthermore, the entire transfer chamber 1 is made of TC4 titanium alloy material, which has high strength and low density. Therefore, the device has the advantages of small size and weight, and is suitable for use on ships. After completing the pressure-maintaining transfer of deep-sea animals on the ship, the deep-sea animals can be cultured and observed for a short period of time, and then returned to the land laboratory for docking and transfer with the animal culture device for long-term culture, observation, and experiments.

[0034] Furthermore, one end of the driving unit is hinged to the top of the first platform 21, and the other end is hinged to the bottom of the second platform 22. This connection mode enables the driving unit to drive the second platform 22 and the transfer bin 1 disposed on the second platform 22 to flexibly adjust their posture relative to the first platform 21 when the driving unit is extended or shortened.

[0035] Specifically, the two ends of the driving unit are respectively connected to the first platform 21 and the second platform 22 by hinges. This design allows the driving unit to achieve a certain range of rotation while maintaining a certain rigidity. Therefore, when the driving unit is extended or shortened along its own axis, it can drive the second platform 22 and the transfer bin 1 thereon to perform translation and rotation in three-dimensional space, thereby achieving precise adjustment of the position of the docking interface 8.

[0036] Furthermore, both ends of the driving unit are provided with a Hooke's hinge 24, and the driving unit is hinged to the first platform 21 and the second platform 22 through the Hooke's hinge 24. This connection mode not only enhances the connection strength between the driving unit and the platform, but also provides greater rotation flexibility and angle adjustment range.

[0037] Specifically, the Hooke's hinge 24 is a hinge structure with two mutually perpendicular rotation axes, which allows the two connected parts to rotate relative to each other in two perpendicular directions. In the device described in claim 3, the two ends of the driving unit are respectively connected to the top of the first platform 21 and the bottom of the second platform 22 through the Hooke's hinge 24. This design allows the driving unit to extend or shorten, and at the same time, it can also drive the second platform 22 and the transfer bin 1 thereon to perform more complex posture adjustments through the rotation function of the Hooke's hinge 24.

[0038] Furthermore, the number of drive units is six. These six drive units are arranged and connected between the first platform 21 and the second platform 22 in a specific manner, and act together on the transfer warehouse 1 to ensure that the docking interface 8 thereon has a complete six degrees of freedom. By precisely controlling the extension or shortening of the six drive units, and coordinating the Hooke's hinge 24 between them and the first platform 21 and the second platform 22, fine adjustment of the position and posture of the transfer warehouse 1 can be achieved, thereby ensuring that the docking interface 8 can accurately dock with the target interface. The design of the six drive units not only provides sufficient driving force and adjustment range, but also enhances the stability and reliability of the system through redundant configuration. Even if one or several of the drive units fail, the remaining drive units can still work together to maintain the basic motion control capability of the transfer warehouse 1.

[0039] Furthermore, the driving unit may be any one of an electric cylinder 23 , a pneumatic cylinder, and an oil cylinder. The driving unit of the present application is preferably an electric cylinder 23 .

[0040] Further, the six drive units are specifically configured as a first electric cylinder 231, a second electric cylinder 232, a third electric cylinder 233, a fourth electric cylinder 234, a fifth electric cylinder 235 and a sixth electric cylinder 236, and they are arranged in a specific order and relative position. Specifically, the upper end of the first electric cylinder 231 is close to the upper end of the second electric cylinder 232, forming a group of upper adjacent electric cylinders 23 pairs; the lower end of the second electric cylinder 232 is close to the lower end of the third electric cylinder 233, forming a group of lower adjacent electric cylinders 23 pairs; similarly, the upper end of the third electric cylinder 233 is close to the upper end of the fourth electric cylinder 234, the lower end of the fourth electric cylinder 234 is close to the lower end of the fifth electric cylinder 235, and the upper end of the fifth electric cylinder 235 is close to the upper end of the sixth electric cylinder 236, respectively forming another three groups of adjacent electric cylinders 23 pairs; finally, the lower end of the sixth electric cylinder 236 is close to the lower end of the first electric cylinder 231, so that the entire arrangement presents a ring-shaped or approximately ring-shaped arrangement.

[0041] This unique arrangement not only ensures that the six drive units can evenly distribute the forces acting on the transfer bin 1, thereby improving the accuracy and stability of docking, but also achieves more delicate and flexible control of the position and posture of the transfer bin 1 through the close cooperation between adjacent electric cylinders 23. Each electric cylinder 23 can be extended or shortened independently, and through their synergy, the transfer bin 1 can be easily adjusted accurately in six degrees of freedom. This arrangement also helps to optimize the overall structure of the device, so that the device can maximize the use of space while maintaining compactness and lightness, thereby improving the efficiency and practicality of the device.

[0042] In addition, considering that the overall height of the device should not be too high in order to facilitate the operation of technicians during use, the radius of the hinge circle of the upper and lower platforms in the transfer docking platform and the angle between the hinge points, the length of the electric cylinder and the telescopic range are determined with specific parameters. The specific parameter sizes are shown in the following table. The upper hinge point and the lower hinge point of the electric cylinder are as follows: Figure 5 shown.

[0043] Table 1 Transfer and docking platform structure parameters

[0044]

[0045] When the transfer chamber 1 is docked with the animal sampler, Figure 6 As shown, enter the refrigerated container F, place the deep-sea animal sampler A on the cart B, which is on the fixed rail C, push the ship-borne pressure-maintaining transfer device E onto the rail C, and step on the brake to lock it after approaching the sampler A along the rail. Open the transfer platform 2, control it through the host computer and the handle, calibrate it with the human eye, complete the fine adjustment of the posture, realize the docking of the female head 91 and the male head 9, and then install the clamp-type quick-clamp flange structure 92, and install the screws. At this time, the screws do not need a large pre-tightening force, and only four screws are needed, which is easy to assemble and disassemble.

[0046] Furthermore, a water supply module 3 is provided on the transfer chamber, and the water supply module 3 is used to fill water in the sealed cavity to a set pressure to ensure that the deep-sea animals can be in a pressure condition similar to their native environment during the transfer process, thereby improving the survival rate of the transfer.

[0047] The water supply module 3 is mainly composed of a first pipeline 31 and a second pipeline 32, both of which are closely connected to the sealed cavity to ensure that water can flow in and out smoothly. On the first pipeline 31, a water supply pump 311, a stop valve 312 and a pressure gauge 313 are arranged in sequence. The water supply pump 311, as a power source, is responsible for pumping water from an external water source into the sealed cavity; the stop valve 312 is used to control the on and off of the water flow so that the water source can be quickly cut off when needed; the pressure gauge 313 displays the pressure value in the sealed cavity in real time, providing accurate pressure information for the operator. On the second pipeline 32, a pressure regulating valve 321 and a flow meter 322 are arranged. The pressure regulating valve 321 is used to adjust the pressure of water flowing out of the sealed cavity to ensure that the pressure in the sealed cavity can be stabilized within a set range; the flow meter 322 is used to measure the flow rate of the outflowing water to help the operator understand the water consumption during the transfer process so as to replenish it in time. When the pressure approaches the set value, the pressure regulating valve 321 starts to work and cooperates with the flow meter 322 to continuously control the opening size to control the water pressure in the cavity to fluctuate within a small range.

[0048] Furthermore, an auxiliary thermal insulation module 4 is provided on the transfer chamber, which is designed to provide deep-sea animals with a transfer environment close to the temperature of their native environment through precise temperature control, thereby minimizing the physiological stress caused by temperature changes.

[0049] The auxiliary insulation module 4 is mainly composed of the following parts: first, the refrigeration equipment 41 arranged outside the transfer warehouse 1, as the power source and temperature regulation center of the entire cooling cycle, is responsible for providing the cooling medium and controlling its temperature; secondly, the insulation cover wrapped around the outside of the transfer warehouse 1 can effectively reduce the impact of the external environment on the temperature inside the transfer warehouse 1 and maintain the stability of the temperature inside the warehouse; thirdly, the spiral copper tube 42 arranged inside the sealed cavity, which serves as the heat exchange interface between the cooling medium and the water body in the sealed cavity, realizes the temperature exchange through heat conduction; in addition, the insulation tube 43 connecting the refrigeration equipment 41 and the spiral copper tube 42 ensures the efficient and stable transmission of the cooling medium between the refrigeration equipment 41 and the spiral copper tube 42; finally, the temperature probe 44 extending into the sealed cavity monitors the temperature inside the sealed cavity in real time, and feeds back the information to the refrigeration equipment 41, so as to adjust the refrigeration power according to actual needs and realize precise temperature control.

[0050] These components together form a closed-loop cooling cycle. When the temperature in the sealed cavity needs to be lowered, the refrigeration equipment 41 is started, and the cooling medium flows into the spiral copper tube 42 through the insulation tube 43, and heat is exchanged with the water in the sealed cavity in the copper tube. After absorbing the heat of the water, the cooling medium flows back to the refrigeration equipment 41 through the insulation tube 43 for cooling again, and the cycle is repeated until the temperature in the sealed cavity drops to the set value. Conversely, when the temperature needs to be increased, it can be achieved by adjusting the working mode of the refrigeration equipment 41 or closing the cooling cycle. Through these careful designs of the auxiliary insulation module 4, deep-sea animals can be in a temperature-stable and comfortable environment during the transfer process, which is of great significance for improving their survival rate and reducing physiological stress during transportation.

[0051] Furthermore, a feeding module 5 is provided on the transfer chamber, and the module is designed to conveniently and quickly feed bait into the sealed chamber to ensure that deep-sea animals can get sufficient nutritional supply during the transportation process.

[0052] The bait feeding module 5 is mainly composed of three parts: a bait feeding chamber 51, a first connecting chamber 52 and a first ball valve 53. Among them, the bait feeding chamber 51 is a space for storing bait, the first connecting chamber 52 is used as a transition space between the bait feeding chamber 51 and the sealed chamber, and the first ball valve 53 is arranged between the bait feeding chamber 51 and the first connecting chamber 52. When bait needs to be fed, water is pre-filled in the bait feeding chamber 51 to high pressure, and when the pressure on both sides of the ball valve is equal, the first ball valve 53 is opened, and the bait falls from the bait feeding chamber 51, through the first ball valve 53, the connecting chamber, and into the sealed chamber due to gravity.

[0053] Furthermore, the deep-sea animal ship-borne pressure-maintaining transfer device described in the present invention also includes a sewage discharge module 6, which is used to treat the sewage generated by deep-sea animals during the transfer and cultivation process. The sewage discharge module 6 specifically includes a sewage discharge guide plate 61, a second connecting chamber 62, a second ball valve 63 and a sewage discharge chamber 64. The sewage discharge guide plate 61 is arranged at the bottom of the sealed cavity, and its design allows the sewage discharged by the animal to smoothly converge to the middle position of the bottom of the sealed cavity. In this way, the sewage will not accumulate in the corners of the cavity or in places that are difficult to clean, thereby simplifying the subsequent cleaning work. One end of the second connecting chamber 62 is connected to the bottom of the sealed chamber, and the other end is detachably connected to the sewage discharge chamber 64. This design allows the sewage discharge chamber 64 to be easily removed from the second connecting chamber 62 when the sewage needs to be cleaned, without interrupting the operation of the entire transfer platform 2. The second ball valve 63 is arranged between the second connecting chamber 62 and the sewage discharge chamber 64 to control the discharge of sewage. When it is necessary to clean the dirt, the second ball valve 63 can be opened to allow the dirt to enter the drainage chamber 64 from the sealed cavity through the second connecting chamber 62 and the second ball valve 63. After the cleaning is completed, the second ball valve 63 is closed, and the drainage chamber 64 is reinstalled to continue the transfer and cultivation of deep-sea animals. Through the synergistic effect of these components of the drainage module 6, the deep-sea animal ship-borne pressure-maintaining transfer device described in the present invention can effectively handle the dirt generated by deep-sea animals during the transfer and cultivation process, and keep the environment in the transfer chamber 1 clean and stable.

[0054] Furthermore, a camera and lighting module 7 is also provided on the transfer chamber 1, and the module is intended to facilitate technicians to observe the status of deep-sea animals and ensure safety during the transfer and cultivation process.

[0055] The camera and lighting module 7 includes two protective cavities 71 arranged on the transfer bin 1, and a front cover 72, a sapphire lens 73 and a transmission rotating block 74 are arranged in the protective cavities 71. The difference is that a camera 75 is arranged in one protective cavity 71, and an LED lamp 76 is arranged in the other protective cavity 71; the protective cavity 71 provides additional protection for the camera 75 and the lighting equipment to prevent the intrusion of water and other impurities; the front cover 72 is used to protect the camera 75 and the lighting equipment inside the module, and at the same time provides an observation window, which has high light transmittance and wear resistance, and can clearly capture the image of deep-sea animals; the sapphire lens 73 has high light transmittance and wear resistance, which enables the camera 75 to clearly capture the image of deep-sea animals; the transmission rotating block 74 is used to adjust the field of view of the camera 75, so that technicians can observe deep-sea animals in all directions; the LED lamp 76 provides sufficient lighting for the observation area to ensure the clarity of the image.

[0056] like Fig. 9As shown, when the ship docks, the ship-borne pressure-maintaining transfer device is unloaded and transported to the onshore laboratory, where it can be docked with the laboratory culture device G in a manner similar to that of the sampler A. A docking cavity H with male connectors 9 at both ends needs to be added, but at this time, no guide rail is required. After locking the cart, the transfer platform 2 can be controlled to complete the docking.

[0057] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
