Description

Technical Field

[0001] This utility model relates to the field of marine measurement technology, and in particular to a submersible full-depth marine measurement buoy. Background Technology

[0002] According to reports, in 2014, the Chinese Navy's submarine 372 experienced an underwater depth slippage incident, but ultimately survived thanks to the combined efforts of all crew members. This crisis was primarily caused by encountering a changing sea level.

[0003] The vast ocean is fraught with danger, and to prevent such situations from recurring, it is essential to understand water patterns. However, currently, this can only be done using ocean buoys. The main types of ocean survey buoys currently available are as follows:

[0004] I. Shipborne Oceanographic Survey Buoys: Shipborne oceanographic survey buoys are primarily carried by surface ships. When the ship reaches the area to be measured, the buoy is deployed into the sea. The buoy sinks under its own weight, and ocean profile data is measured in real time during the descent. After the measurement is completed, the data is transmitted back to the terminal on the ship via a data connection line at the buoy's stern. Although this method can accurately measure ocean profile data at all depths, surface ships themselves do not need the ocean profile data; it is the underwater submersible that needs it. In practical engineering applications, it is also necessary to transmit the data measured by the surface ship to the underwater submersible.

[0005] II. Submersible Oceanographic Survey Buoys: Submersible oceanographic survey buoys are released by submarines or submersibles and sink naturally under their own weight, measuring oceanographic data in real time during the sinking process. The measured data is transmitted back in real time through an underwater acoustic communication unit at the stern of the buoy. Submersible oceanographic survey buoys have the following problems in their use: (1) They cannot measure the full depth; the measured depth depends on the depth at which the submarine or submersible releases the buoy; (2) The buoy uses underwater acoustic communication to transmit data, which has poor stability and is limited in distance during communication.

[0006] In summary, existing oceanographic buoys have many shortcomings, therefore a submersible full-depth oceanographic buoy is needed to solve the above problems. Utility Model Content

[0007] The purpose of this utility model embodiment is to provide a submersible full-depth oceanographic buoy, which aims to solve the problems mentioned in the background art.

[0008] This utility model embodiment is implemented as follows: a submersible full-depth oceanographic buoy includes: a protective shell, which is divided into a sensor module compartment, a self-sinking control compartment, a cable-laying section, and a buoyancy cavity. The sensor module compartment is located at the front of the protective shell, the self-sinking control compartment is located in the middle of the protective shell, the cable-laying section is located at the rear of the buoy, and the buoyancy cavity is also located at the rear of the buoy; a sensor module, which is installed in the sensor module compartment and is used to detect ocean temperature, salinity, and depth profile data; the sensor module is connected to a control module installed in the self-sinking control compartment; and an optical fiber coil at the buoy end, which is installed in the cable-laying section of the protective shell and connected to the control module.

[0009] Preferably, the sensor module includes: a temperature sensor installed inside the sensor module compartment; a depth sensor installed inside the sensor module compartment on one side of the temperature sensor; and a salinity sensor installed inside the sensor module compartment on one side of the depth sensor. The temperature sensor, depth sensor, and salinity sensor are all connected to the control module.

[0010] Preferably, the control module includes: a main controller, which is installed inside the self-sinking control cabin and connected to the sensor module; the main controller is connected to an optical module, a battery unit, and a magnetic switch installed inside the self-sinking control cabin; the battery unit is used to power the main controller; the magnetic switch is used to control the opening and closing of the main controller; an optical fiber coil at the buoy end is connected to the optical module; the optical module is used to illuminate the optical fiber coil at the buoy end; a first water injection valve, which is installed on the self-sinking control cabin and connected to the main controller; the main controller is also connected to a second water injection valve installed on the self-sinking control cabin; the main controller is used to control the opening and closing of the first water injection valve and the second water injection valve.

[0011] The submarine-launched full-depth oceanographic buoy provided by this utility model can not only achieve full-depth ocean profile data measurement, but also transmit data back using fiber optic communication, which is more stable and reliable. Furthermore, it can be directly mounted on submarines or submersibles and launched using existing launch devices.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and do not limit the present utility model.

[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0017] Please see Figure 1 and Figure 2 This utility model provides a submersible full-depth oceanographic survey buoy, which includes:

[0018] The protective shell 1 is divided into a sensor module compartment, a self-sinking control compartment, a line-laying section, and a buoyancy cavity. The sensor module compartment is located at the front of the protective shell 1, the self-sinking control compartment is located in the middle of the protective shell 1, the line-laying section is located at the rear of the buoy, and the buoyancy cavity is also located at the rear of the buoy. The sensor module 2 is installed in the sensor module compartment and is used to detect ocean temperature, salinity, and depth profile data. The sensor module 2 is connected to the control module 3 installed in the self-sinking control compartment. The buoy end fiber optic cable 4 is installed in the line-laying section of the protective shell 1 and is connected to the control module 3.

[0019] Oceanographic Measurement Principle: When the buoy is in operation, the submersible full-depth oceanographic measurement buoy is placed inside the QT launching device and connected to the onboard control terminal via a traction optical cable. The sensor module 2 in the buoy operates at a depth range of 20m to full depth. When a mission is required, the submersible full-depth oceanographic measurement buoy is launched from outside the ship. After launch, as the QT moves, the external traction cable is gradually straightened. The buoy and float follow the QT's movement, while the buoy continues to move forward due to inertia. Because an automatic release mechanism is used between the buoy and float, they automatically release and separate. After separation, the buoy rises due to positive buoyancy, at which point its center of gravity is lower and its center of buoyancy is higher. The lines of the float and buoy begin to be released simultaneously due to tension. After the buoy rises to the surface, its center of gravity and center of buoyancy are roughly aligned. It then floods and sinks to 1500m. As the buoyancy continues to descend, the center of buoyancy changes due to the flooding, while the center of gravity remains constant. During its descent, the buoy inverts 180 degrees. During its ascent and descent, the buoy collects and uploads real-time ocean profile temperature, salinity, and depth parameters at a frequency of once per second. Upon completion of the measurement mission, the onboard control system issues self-destruct and cable-cutting commands to sever the towing cable, jettison the buoy, and end the mission. Each measurement session lasts approximately 0.5 hours.

[0020] like Figure 1 As shown, in a preferred embodiment of the present invention, the sensor module 2 includes: a temperature sensor 21 installed in the sensor module compartment; a depth sensor 22 installed in the sensor module compartment on one side of the temperature sensor 21; and a salinity sensor 23 installed in the sensor module compartment on one side of the depth sensor 22. The temperature sensor 21, the depth sensor 22, and the salinity sensor 23 are all connected to the control module 3.

[0021] like Figure 1 As shown, in a preferred embodiment of this utility model, the control module 3 includes: a main controller 31, which is installed in the self-sinking control cabin and connected to the sensor module 2. The main controller 31 is connected to an optical module 32, a battery unit 33, and a magnetic switch 34, all installed in the self-sinking control cabin. The battery unit 33 supplies power to the main controller 31, and the magnetic switch 34 controls the opening and closing of the main controller 31. The buoy fiber optic cable 4 is connected to the optical module 32, and the optical module 32 illuminates the buoy fiber optic cable 4. A first water injection valve 35 is installed on the self-sinking control cabin and connected to the main controller 31. The main controller 31 is also connected to a second water injection valve 36, which is installed on the self-sinking control cabin. The main controller 31 controls the opening and closing of the first water injection valve 35 and the second water injection valve 36.

[0022] Buoy Workflow: Before launch, sensor module 2 performs a power-on self-test to check its actual working status. After a successful self-test, it prepares for launch. The buoy launches and begins to rise under its own buoyancy. The fiber optic cable at the float end separates from the buoy, and the QT (Qun-Tunneling Tunnel) tows the buoy forward while the other end of the fiber optic cable at the float end continues to be released. The buoy, carrying sensor module 2, rises to the surface and then the main controller 31 opens the first water injection valve 35 and the second water injection valve 36, allowing water to enter the self-sinking control cabin. The buoy adjusts its buoyancy. Once the buoy buoyancy conversion is complete, it begins to sink. During the sinking process, the temperature sensor 21, depth sensor 22, and salinity sensor 23 measure ocean temperature, salinity, and depth profile information in real time and transmit it back to the ship. When the buoy reaches the designated measurement depth, the measurement task is completed, and the in-cabin display and control terminal issues a cable cutting or separation command. Upon receiving the cutting command, the outboard launch accessory cuts or separates the cable and sends a success signal, completing the cutting and ending the task.

[0023] In addition, the buoy's launch accessory is adapted to an outboard launch system, which mainly consists of a detachable connector, launch control cable, and adapter module. The in-cabin terminal for controlling the outboard launch system to launch the buoy includes a touch control display screen and a communication main control module, enabling information storage, information uploading, and fiber optic cable cutting or disconnection control.

[0024] The buoy's outer diameter and length are adapted to the requirements of the outboard launch system. The buoy mainly consists of a sensor module compartment, a self-sinking control compartment, a line-laying section, and a buoyancy cavity. The sensor module compartment is located at the top of the buoy and houses sensor modules 2, ensuring that sensor modules 2 can always measure environmental information at the current depth during ascent and descent. The self-sinking control compartment is located in the middle of the buoy and provides buoyancy to the buoy during ascent, enabling the buoy to sink after buoyancy is submerged. The self-sinking control compartment is the core compartment for realizing the buoy's functions, and it houses the main controller 31, optical module 32, battery unit 33, magnetic switch 34, first water injection valve 35, and second water injection valve 36. The line-laying section is located at the rear of the buoy and houses the buoy end fiber optic cable bundle 4. The buoyancy cavity is also located within the line-laying section.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
