Technical Field

[0001] The invention belongs to the technical field of ocean monitoring, and in particular relates to a miniaturized ocean profile multi-parameter real-time monitoring device. Background Art

[0002] Coastal estuaries and marine engineering construction are significantly affected by hydrodynamics and sediment environment conditions. In order to improve the safety assurance capabilities of coastal estuaries and marine engineering construction, continuous observation and investigation of hydrological environmental elements is the basis and prerequisite for related work. Conventional hydrological environmental observation elements mainly include multi-factor information such as waves, tides, temperature, salinity, depth and turbidity information. Conventional observation methods mainly rely on ship-borne human measurement, which has low work efficiency, high manpower and material costs, and cannot meet the real-time data acquisition needs. Existing automated marine multi-parameter observation methods, such as profile monitoring based on electric winches and layered sensor deployment, have problems such as large equipment size, high construction cost, and difficulty in movement. At present, there is an automatic sinking and floating ocean profile temperature, salinity, and turbidity monitoring device that can realize the observation and data transmission of equipment along the ocean profile, but there are the following areas that need to be improved: (1) The observation parameters of the device are for temperature, salinity, and turbidity profiles, and lack integrated observation of parameters such as waves and tides; (2) The device relies on the battery compartment carried by the sinker and floater for power supply. The volume control of the sinker and floater is limited, and the sinking and floating effect is easily affected in waters with high flow rates.

[0038] As a preferred embodiment, the head of the sinking and floating motion unit is also provided with a protective cover having several holes of the same size, and the interfaces of the water temperature sensor, salinity sensor, turbidity sensor and pressure sensor pass through the holes on the protective cover.

[0039] Specifically, the sinking and floating motion unit is a non-fixed installation, which is equipped with multi-parameter sensors, underwater thrusters, underwater cables, positioning and wireless transmission modules, etc. It obtains profile observation data through the sinking and floating motion between the water surface and underwater and completes remote communication transmission on the water surface;

[0040] Multi-parameter sensor: including water temperature, salinity, turbidity, and pressure sensors, all located at the head of the sinking and floating motion unit. During the sinking and floating process of the motion unit, the hydrological multi-parameters of the entire profile water depth are recorded, and the water discharge status of the sinking and floating unit is judged through the pressure sensor;

[0041] Underwater thruster: installed at the bottom of the motion unit, using a reverse dual thruster method to provide thrust for the motion unit; at the same time, the sinking and floating motion unit is designed with large buoyancy at the head and small buoyancy at the bottom to ensure upward thrust underwater;

[0042] Counterweight: Maintain the posture of the sinking and floating motion unit under the influence of water flow, and ensure that the sinking and floating motion unit continues to obtain the thrust of the propeller toward the water surface;

[0043] Underwater cable: The cable connects the underwater fixed unit and the moving unit to realize power supply and data transmission between the two;

[0044] Positioning and wireless transmission module: Located on the top of the sinking and floating motion unit, it sends the position and measurement data information to the background service center after surfacing.

[0045] Specifically, the underwater fixed unit is equipped with various modules such as the power supply end, wave and current sensor, system controller, underwater electric winch, etc., to realize the functions of installation, fixation, power supply, system operation control, etc. of the overall equipment; the structure of the underwater fixed unit is as follows Figure 6 shown.

[0046] System controller: The integrated controller is the core of the observation station. The control system automatically collects, processes, and stores observation data according to the set working sequence, and sends the processed data to the shore-based data center in real time through the communication system; it controls the system power supply, controls the power supply and power failure of each part, and detects the various working states of the system. It is responsible for data collection, processing and transmission, realizing the integrated observation goal of equipment research and development.

[0049] Underwater winch: controlled by the system controller to realize the retraction and release of the underwater cable, and participate in controlling the movement of the sinking and floating motion unit.

[0050] Equipment operation process:

[0051] The equipment is powered by the built-in battery pack of the underwater fixed unit, and the system controller controls the data collection and transmission. The wave and tidal current sensors are connected to the power supply group and the system control end through cables, and the system control end controls the data collection work to complete the acquisition of profile wave and tidal current data, which are then transmitted to the sinking and buoying motion unit via the communication cable and sent to the background server by the communication antenna.

[0052] The floating process of the sinking and floating motion unit: The sinking and floating motion unit is connected to the system controller through a cable via an underwater electric winch. When the motion unit floats up, the system controller controls the underwater electric winch to release the cable. At the same time, the propeller of the sinking and floating motion unit starts working to realize the floating of the sinking and floating motion unit, and the carried sensors start working to collect the profile hydrological data during the floating process; after the sinking and floating motion unit floats to the surface, the system obtains the water outlet signal through the pressure sensor, the underwater winch gradually stops releasing the cable, and the propeller starts to work at a low gear to maintain the water outlet state of the head of the sinking and floating motion unit, and the communication antenna at the head of the sinking and floating motion unit transmits the collected data to the background server.

[0053] Sinking process of the floating unit: According to the water outlet time set by the system, after the water outlet is completed, the system controls the propeller to stop working, and at the same time the underwater winch recovers the cable. Under the action of the cable tension and the deadweight of the floating unit, the sinking process of the equipment is realized. When the cable is recovered to the floating unit and close to the underwater fixed unit, the system stops working and maintains a silent state until the next work starts.

[0054] The built-in battery of the sinking and floating motion unit can meet the short-term sinking and floating motion of the motion unit;

[0055] The power supply group of the underwater fixed unit: 1. Provide power for the tidal wave sensor module; 2. Provide power for the underwater winch; 3. Charge the built-in battery of the motion unit, where the movement of the sinking and buoying motion unit is directly driven by its built-in battery.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
