[0033] The lifting and rotating opening mechanism is installed inside the box body 1 , and the output end of the lifting and rotating opening mechanism is fixedly connected to the box cover 2 , driving the box cover 2 to lift and rotate, thereby opening or closing the biological inlet 101 .

[0034] Specifically, if Figure 6As shown, a buoyant material layer 3 is provided on the inner side of the housing 1 and the inner side of the lid 2. In this embodiment, the outer walls of the housing 1 and lid 2 are made of 316L stainless steel. The buoyant material layer 3 utilizes a conventional glass microbead composite material, which can withstand pressures up to 6,000 meters underwater, exhibits low thermal conductivity, and provides excellent insulation. A seal (not shown) is provided on the inner side of the lid 2 to seal the biological entry port 101. In this embodiment, the seal is a commercially available rubber gasket.

[0035] Specifically, if Figure 6-9 As shown, in this embodiment, the lifting and rotating opening mechanism includes a lifting cylinder 4, a rotating shaft mounting seat 5, a rotating shaft 6, a guide seat 7 and a fixing pin 8. The cylinder barrel of the lifting cylinder 4 is fixedly connected to the bottom of the box body 1, and the output end is fixedly connected to the rotating shaft mounting seat 5. One end of the rotating shaft 6 is rotatably arranged in the rotating shaft mounting seat 5 through a rotating bearing. The rotating shaft mounting seat 5 plays an axial limiting role for the rotating shaft 6 and rises and falls together with the rotating shaft 6; the other end of the rotating shaft 6 is fixedly connected to the box cover 2 as the output end of the lifting and rotating opening mechanism. A rotating guide groove 601 is provided in the middle of the rotating shaft 6. The guide seat 7 is fixed to the inner side surface of the box body 1. The rotating shaft 6 passes through the guide seat 7. The guide seat 7 plays a guiding and limiting role for the rotating shaft 6. The fixing pin 8 is penetrated in the guide seat 7 and passes through the rotating guide groove 601 at the same time. During the lifting process, the rotating shaft 6 is limited by the fixing pin 8 and the rotating guide groove 601, and then rotates. In this embodiment, the housing 1 is provided with a pipe interface 9, which is connected to the lift cylinder 4 and an external hydraulic station via pipes. The lift cylinder 4 is a commercially available product, and the connection methods of the pipe interface 9, the lift cylinder 4 and the external hydraulic station are all conventional. The provision of a lifting and rotating opening mechanism facilitates the opening and closing of the lid 2. When the lid 2 is closed, the lift cylinder 4 is used to tightly press the lid 2 downward, ensuring a reliable seal.

[0036] Specifically, in this embodiment, an isolation cover (not shown in the figure) for isolating seawater and organisms is installed in the box body 1 and on the outside of the lifting and rotating opening mechanism to prevent seawater and organisms from contacting the lifting and rotating opening mechanism, thereby protecting the lifting and rotating opening mechanism.

[0037] Specifically, if Figure 6 As shown, in this embodiment, an inclined plate 10 is provided at a position corresponding to the biological entry port 101 in the box body 1. One end of the inclined plate 10 is fixed to the inner side surface of the box body 1 and the other end is inclined downward. The inclined plate 10 facilitates the smooth entry of the captured biological into the box body 1.

[0038] Specifically, if Figure 3 、 Figure 4 、 Figure 10 and Figure 11As shown, in this embodiment, a limit stop rod 11 is provided on the box cover 2, and a limit stop block mechanism used in conjunction with the limit stop rod 11 is provided on the box body 1. The limit stop block mechanism includes a limit stop block mounting seat 12, a guide pin 13, a limit stop block 14 and a spring 15. The limit stop block mounting seat 12 is fixed to the box body 1, and the guide pin 13 is passed through the limit stop block mounting seat 12. The limit stop block 14 and the spring 15 are respectively sleeved on the guide pin 13. One end of the limit stop block 14 abuts against the box body 1, and the other end abuts against one end of the spring 15. The other end of the spring 15 abuts against the limit stop block mounting seat 12. The limit stop block 14 is provided with a guide inclined surface 1401 for blocking the limit stop rod 11 and a clamping groove 1402 for clamping the limit stop rod 11. The limit stopper 11 rotates with the box cover 2 and is stopped by the guide slope 1401 of the limit stopper 14. The limit stopper 11 slides downward along the guide slope 1401 and is locked in the engaging groove 1402. The limit stopper 14 presses the limit stopper 11 under the elastic force of the spring 15. The setting of the limit stopper mechanism can limit the box cover 2 and prevent it from being rotated out too much.

[0039] Working principle:

[0040] When it is necessary to open the box cover 2, the output end of the lifting cylinder 4 extends out, and drives the rotating shaft 6 to rotate while rising, so that the box cover 2 is lifted and unscrewed; when it is necessary to close the box cover 2, the output end of the lifting cylinder 4 contracts, and drives the rotating shaft 6 to rotate while descending, so that the box cover 2 is rotated back and pressed tightly, closing the biological entry port 101 and maintaining a seal; by setting the lifting and rotating opening mechanism, the box cover 2 can be easily opened and closed, and by using the lifting cylinder 4, when closing the box cover 2, the box cover 2 can be tightly pressed downward to ensure a reliable sealing effect; by setting the limit block mechanism, the box cover 2 can be limited to prevent the box cover 2 from being excessively rotated out.
