Description
Technical Field
The invention relates to the field of offshore informatization, a frame platform is supported by a pontoon with a horizontal propeller and a vertical propeller, a photovoltaic cell panel is deployed, the automatic control of the propeller realizes the relative stability of the platform on the sea surface, a low-cost deployment platform which is nearly all-weather is provided for communication, monitoring, investigation and other equipment, a power supply is continuously provided, the manual duty is replaced to the greatest extent, and an informatization means on land is effectively extended to the sea.
Background
The ocean territory of our country is wide, has the ocean territory of 3.2 ten thousand kilometers length, surrounds the ocean territory more than 300 ten thousand square kilometers, and the network video monitoring that has been widely used at present in the land environment, unmanned aerial vehicle information technology such as take photo by plane still can't popularize in sea, especially open sea area, receive the limitation of technologies such as offshore power supply, data transmission, very high frequency radio station on the ship, can't realize video signal's transmission, and the video monitoring of sea covers still blank.
In order to deploy the relay equipment and the antenna for wireless communication on the sea surface, the anchor chain is required to fix the supporting component on the sea surface on the sea bottom so as to ensure the relative stability of the position of the antenna, the average water depth of the east sea area of China reaches 349 meters, the deepest 2322 meters, the average depth of the south sea is 1212 meters, and the maximum depth reaches 5559 meters. Such depths in open sea areas are difficult to achieve if anchor chains are used to secure equipment components on the sea surface.
The unmanned aerial vehicle is used on the sea to carry out monitoring, mapping, early warning and other works very commonly, but is limited by the cruising ability of the unmanned aerial vehicle, and the unmanned aerial vehicle can only be used in a certain space-time range under the support of a ship, so that long-time unmanned on duty is difficult to realize, and especially when stormy waves are large, the unmanned aerial vehicle is lost or damaged due to the lack of safety protection.
The semi-submersible type sea surface working platform deployed in certain sea areas has larger volume and high manufacturing cost, is generally used for more exploration or exploitation functions and the like, and cannot be used for carrying wireless communication equipment or unmanned aerial vehicles.
Disclosure of Invention
The invention aims to create a low-cost miniaturized offshore floating platform, and the buoyancy generated by a submerged pontoon is equivalent to the total weight of the platform and load, so as to save the energy consumption generated by driving a vertical propeller. The support columns and the frame platform above the pontoons have smaller cross-sectional areas so as to reduce transverse impact force generated by sea waves, disperse the deployed photovoltaic cell panels, reduce wind resistance and sea wave impact as much as possible and facilitate the relative stability of horizontal positions.
According to the data statistics of China ocean climate monitoring month report, the number of days that the ocean area of the east China sea appears 3.5 meters or more in wave height in 2021 is 76 days, the ocean area of the south China sea is 97 days, and the total number of the ocean areas is 20 through typhoons and cyclones; the number of days that the sea area of the east China sea in 2022 appears with wave height of more than 3.5 meters is 86 days, and the sea area of the south China sea is 76 days, and the total number of the sea areas is 21 by typhoons and cyclones. According to the design, the frame platform is supported by buoyancy and is 3 meters away from the sea surface, so that the application requirements under most climatic conditions can be met.
The photovoltaic cell panel scattered and covered above the platform is used as an energy source, and data of an inclination sensor, a positioning sensor and a pressure sensor carried in a fixed space of the load equipment are transmitted to a main control computer in the pontoon in real time, and a software program drives a vertical propeller on the side wall of the pontoon, a horizontal propeller below the pontoon and an axial steering engine matched with the vertical propeller and the horizontal propeller according to data change of the sensors.
All parts of the offshore floating platform and the carried load thereof are made of anti-corrosion and anti-pressure materials, and all parts and connecting devices have enough strength to ensure long-time stable operation in a severe sea environment.

Detailed Description
When the fluctuation of the sea wave makes the platform change the inclination angle of the vertical direction, the main control computer (350) controls the vertical propeller (170) on the side wall of the pontoon to change the rotating speed and the direction according to the numerical value change of the inclination angle sensor (220), and counteracts the fluctuation of the sea wave, so that the vertical position of the pontoon is kept relatively static within a certain range, and the pontoon support maintains the horizontal state of the frame platform (100).
When the flow of the seawater deviates the platform from the initial position or rotates the platform by a certain horizontal angle, the main control computer (350) controls the horizontal propeller (160) and the steering engine (330) below the pontoon to change the rotating speed and the direction according to the numerical value changes of the inclination sensor (220) and the positioning sensor (210), counteracts the position changes generated by the ocean currents, corrects the position and the angle of the platform and maintains the relative rest of the platform.
When the horizontal position of the platform needs to be adjusted, the main control computer (350) controls the horizontal propeller (160) and the steering engine (330) below the pontoon to change the rotating speed and the rotating direction according to the longitude and latitude of the target position and the longitude and latitude data of the current position, so as to push the platform to navigate to the target position.
When the sea area where the floating platform is located is small in stormy waves, the main control computer automatically controls the rotating speed and the rotating direction of the horizontal propeller (160) and the vertical propeller (170), and the relative position of the frame platform is dynamically maintained to be stable. When the sensor detects that the sea wave height exceeds the safety range, the main control computer (340) controls the vertical propeller (170) to enable the platform to sink into the sea water, the sea current is relatively stable and cannot impact and damage the platform and the load.
The above scenario occurs within about 70 to 90 days per year, and in severe sea conditions there are no longer vessels on the sea that are sailing and working, and the equipment on the platform is in a suspended state.
The data collected by the pressure sensor (230) is used as the basis for controlling the water depth of the platform by the main control computer (350). The inclination sensor (220) monitors the sea wave change of the current sea area, and when the sea wave is reduced and the safety condition is met, the platform floats out of the water surface under the control of the vertical propeller (170) and resumes normal operation.
The structural design of the platform meets the requirement that the gravity center of the whole body is lower, and even if the platform is overturned by wind and waves, the vertical propeller (170) can be submerged in the sea water. The main control computer (350) judges that the platform is in a capsizing state according to the data of the inclination angle sensor (220) and can control the vertical propeller (170) to realize the actions of sinking, overturning and the like in water so as to restore the original orientation of the platform.
A battery pack (310) located within the power buoy (130) and the main control buoy (140) provides sufficient power for the platform and the load equipment. The photovoltaic cell panel (110) with a large enough area continuously generates electricity in sunlight to supplement the electric energy for the storage battery, so that the storage battery (310) has enough electric energy reserve in the period of severe sea conditions and the platform immersed in water.
Further, the offshore floating platform can be provided with a take-off and landing, fixing and charging interface of the unmanned aerial vehicle, and a near-weather berthing and charging guarantee platform is provided for the offshore unmanned aerial vehicle.
Further, a plurality of offshore floating platforms can be provided with wireless network transmission equipment, so that signal transmission is realized in a relay mode, and network access is provided for an open sea area.
Further, a plurality of offshore floating platforms can be equipped with 4G, 5G mobile communication devices, providing signal coverage for open sea areas through wireless transmission or network connection of undersea optical fiber cables.
The present invention is not limited to the above-described embodiments, which are merely illustrative, not restrictive, of other modifications, which are within the scope of the present invention, without departing from the spirit of the invention.
