Description
Technical Field

Background
Because the ocean area is large, the depth is very deep, the deep sea area and the open sea area are difficult to enter, the deep sea area has huge pressure, the environment corrosiveness and the optical opacity are very large problems, and the bottleneck of developing ocean resources is mainly that the related research of ocean cognition is difficult to carry out. The research and development of ocean resources is to form a complete cognition on the ocean, and the inorganic environment to the organic organism are all needed to be known. The deep sea and open sea environments and biological related data are difficult to obtain, which is a bottleneck for developing ocean resources.
In addition, because the marine environment is complex and the resources are difficult to sample and research, in the deep sea and the open sea, limited resources and samples are obtained at extremely high cost in each scientific research activity, the operation range is very limited, and when the energy sources of ships and submarines remain in general, the ships and submarines must return to the navigation for supplement, the operation period is influenced, and the efficiency is low. Moreover, in seawater, high-frequency internal waves are a main cause of horizontal strain in coastal waters. As these waves propagate in the ocean, they form a converging zone at the top of the wave. It is predicted from existing theoretical models that the depth of water will control plankton accumulation in the trough, where the horizontal strain changes from converging to diverging. When the deep sea resource is developed, the current technology is limited to be difficult to realize vertical descent, and a motion mode with a certain horizontal component is required to be adopted for descent. The most numerous plankton in the ocean are the hard to count, and the bottommost organisms of these food chains are the basis of ocean circulatory metabolism. The ocean contains very abundant resources and is limited by the strong electromagnetic wave absorption capability of the seawater, so that the traditional underwater miniature ocean monitoring buoy is communicated with the shore or a host by a cable, and comprises communication and energy supply, but is not suitable for deep sea and open sea due to the influence of the length and the weight of the cable and waves.

The upper shell 7 is sleeved with the lower shell 16, so that the sliding connection between the upper shell 7 and the lower shell 16 can be ensured, and the sealing effect of a cavity formed by the sleeved upper shell 7 and the lower shell 16 can be ensured. In addition, when the miniature ocean monitoring buoy is placed in water, the pressure of the water to the upper shell 7 and the pressure to the annular sealing ring 14 are used, so that the inner side and the outer side of the annular sealing ring 14 are more closely attached to the inner wall of the upper shell 7 and the outer wall of the lower shell 16, and the miniature ocean monitoring buoy is completely sealed.
As a preferred embodiment, the motor 9 is further sleeved with a coupling 10, two ends of the coupling 10 are respectively connected with the motor rotor and the screw 12, transmission connection between the motor 9 and the screw 12 is realized through the coupling 10, and when the motor 9 rotates, rotational kinetic energy is transmitted to the screw 12 through the coupling 10, so that synchronous rotation of the motor rotor and the screw 12 is realized.

Since the first support plate 4 is fixedly connected with the lower housing 16, the lower housing 16 functions to support both the first support plate 4 and the third support plate 3. In the present embodiment, the first support plate 4 is disposed in the lower housing 16, the third support plate 3 is disposed in the upper housing 7, and the connection between the upper housing 7 and the lower housing 16 can be further fixed by the first support plate 4 and the third support plate 3, so that the upper housing 7 is prevented from being disconnected when sliding up and down relative to the lower housing 16.
