As shown in fig. 1 to 4, some embodiments of the present invention provide a monitoring platform, which is mainly applied to environmental monitoring at sea. The monitoring platform includes a floating body 100 and a floating platform 200, the floating platform 200 being disposed above the floating body 100.
The floating body 100 includes a housing 110, and a power generation device 120, a power management system 130 and a micro control unit 140 disposed in the housing 110. It should be noted that the housing 110 has a hollow structure, and the lower portion of the housing 110 may be any one of a hemisphere, a cone, or an ellipsoid, which can be specifically set according to actual conditions, so as to improve the contact area between the base of the housing 110 and the seawater and the swing efficiency of the housing 110 on the seawater. The lower portion of the housing 110 may also be a conical structure to improve stability of the housing 110 during floating on the sea surface. It should be noted that the housing 110 is a sealed structure, so as to prevent seawater from entering the housing 110.
In addition, the upper part of the housing 110 may be any one of a square, a rectangular or a cylindrical structure, which may be set according to actual conditions.
Meanwhile, the power generation device 120 and the micro control unit 140 are electrically connected to the power management system 130, the power generated by the power generation device 120 is rectified and stored by the power management system 130, and the floating monitoring assembly 300 and the micro control unit 140 are powered, so that the stability of the monitoring assembly 300 and the micro control unit 140 in the working process is improved.
In addition, the floating platform 200 is provided with a monitoring component 300, the monitoring component 300 is used for monitoring the environment on the sea surface in real time, the monitoring component 300 is electrically connected to the power management system 130, and the monitoring component 300 is powered by the power management system 130, so that the real-time monitoring of the marine environment through the floating platform 200 is realized.
As shown in fig. 1 and 2, in some embodiments of the present invention, a power generation tube body 121 is disposed in the power generation device 120, the power generation tube body 121 is filled with a part of liquid, and both ends of the power generation tube body 121 are sealed.
It should be noted that, when the floating body 100 floats on the sea surface, the floating body 100 is rocked on the sea surface by the waves. At this time, the power generation device 120 swings as the floating body 100 swings. Meanwhile, the liquid in the power generation tube body 121 shakes as the power generation tube body 121 shakes, and rubs against the inner wall of the power generation tube body 121. Through the electronegativity difference between the liquid and the power generation tube body 121, electrons are obtained after the inner wall of the power generation tube body 121 is rubbed by the liquid, the potential of the inner wall at one end of the power generation tube body 121 is reduced, so that a potential difference is formed between the first conducting part 122 and the second conducting part 123 of the power generation tube body 121, charges between the first conducting part 122 and the second conducting part 123 are redistributed through electrostatic induction, and the electrons form a circulating directional flow.
The first conductive part 122 is provided at one end of the power generating tube body 121, the second conductive part 123 is provided at the other end of the power generating tube body 121, and the first conductive part 122 and the second conductive part 123 are electrically connected to the lead-out part, respectively. At this time, the first conductive part 122 and the second conductive part 123 are equivalent to an electric energy output end of a generator, when the leading-out part of the power generation device 120 is communicated with the power management system 130, induced charges on the surfaces of the first conductive part 122 and the second conductive part 123 sequentially pass through the leading-out part of the power generation device 120 and the power management system 130 to form current under the driving of a triboelectric potential, and wave energy is converted into electric energy, so that low-frequency wave energy and irregular wave energy are converted into electric energy, the low-frequency wave energy and the irregular wave energy are efficiently collected for a long time, and continuous power supply to the load and the micro-control unit 140 is realized.
Specifically, the invention is based on Maxwell displacement current and utilizes the coupling effect of friction electrification and electrostatic induction principles. When no wave exists, the floating body 100 is not fluctuated by external force, the power generation device 120 is not fluctuated by external force, the positive and negative charge quantities of the inner wall of the power generation tube body 121 are equal, the charge quantity transfer does not occur, and no alternating current is generated.
When waves exist, the floating body 100 is subjected to external force fluctuation to generate inclination and swing, liquid in the power generation tube body 121 periodically swings, the contact area of a liquid-solid contact conductive part on one side of the inner wall of the power generation tube body 121 is reduced, the contact area of a liquid-solid contact conductive part on the other side of the inner wall of the power generation tube body 121 is increased, so that the charge amount in the liquid-solid contact conductive parts is different, and the contact area of the liquid-solid contact area on the inner wall of the power generation tube body 121 periodically changes to cause the charge center to be separated along the axis direction of the power generation tube body 121, so that potential difference is generated. Under the driving of the potential difference, electrons generated by the generating tube body 121 periodically flow through an external load to balance the potential difference of the charges of the generating tube body 121, thereby outputting an alternating current signal.
Low-frequency and unstable wave energy is converted into alternating current energy by the power generation device 120, and alternating current generated by the power generation device 120 is converted into stable low-voltage direct current by the power management system 130, so that power is supplied to the load and the micro control unit 140.
In some embodiments of the present invention, the power generation tube body 121 is a liquid-solid friction nano power generation tube body, and the power generation device 120 is a liquid-solid friction nano power generation device.
The number of the power generation tube bodies 121 may be one, two, or more than two, and may be specifically set according to actual conditions.
In some embodiments of the present invention, the power generation tube 121 is made of one or a combination of polytetrafluoroethylene, polydimethylsiloxane, polyvinyl chloride, polypropylene, and polyethylene, so as to improve the efficiency of obtaining electrons from the power generation tube 121 due to friction, and thus improve the efficiency of converting wave energy into electric energy.
In addition, in some embodiments of the present invention, the micro control unit 140 has a model number TB01-T2S 05.
In some embodiments of the present invention, in order to improve the friction efficiency between the liquid inside the power generation tube body 121 and the power generation tube body 121, the volume of the liquid is 30% to 70% of the volume of the inner tube of the power generation tube body 121. The volume of the liquid in the power generation tube body 121 is set to any one of 30% to 70% of the volume of the inner tube of the power generation tube body 121, and may be set specifically according to actual conditions.
Alternatively, in some embodiments of the present invention, the volume of the liquid is 50% of the volume of the inner tube of the power generation tube body 121, so as to increase the effective contact area between the liquid and the power generation tube body 121, thereby increasing the amount of charges on the surface of the power generation tube body 121.
In some embodiments of the present invention, in order to increase the friction between the liquid and the power generation tube body 121, the liquid is a deionized solution, which may be deionized water, so as to avoid the influence of ions in the liquid on the power generation tube body 121.
In addition, the liquid may also be a solution with ions, such as a sodium chloride solution.
In some embodiments of the present invention, in order to improve the charge transfer efficiency of the power generating tube body 121, the power generating tube body 121 is made of a material from which electrons are easily obtained by a rubbing process. It can be understood that, when electrons are easily obtained during the process that the power generation tube body 121 is rubbed, the larger the potential difference formed on the inner wall of the power generation tube body 121 during the process that the power generation tube body 121 is rubbed, the larger the amount of electric charge transferred to the surface of the power generation tube body 121, the higher the efficiency of the power generation tube body 121 in converting wave energy into electric energy, and thus the efficiency of the power generation tube body 121 in utilizing wave energy is improved.
It should be noted that, as the electric charges generated on the surface of the power generating tube body 121 increase, the larger the current generated when the first conductive portion and the second conductive portion communicate with the external circuit increases, the higher the utilization rate of the wave energy, and the higher the efficiency of the power generating tube body 121 in converting the wave energy into the electric energy.
As shown in fig. 1 and 3, in some embodiments of the invention, the monitoring assembly 300 includes a temperature sensor 310, a wind speed sensor 320, and an air quality sensor 330. The temperature on the sea surface is monitored in real time by the temperature sensor 310, the wind speed on the sea surface is monitored in real time by the wind speed sensor 320, and the air quality on the sea surface is monitored in real time by the air quality sensor 330.
Wherein the temperature sensor 310, the wind speed sensor 320 and the air quality sensor 330 are arranged at intervals on the side of the floating platform 200 far away from the floating body 100. It will be appreciated that the monitoring assembly 300 is located above sea level, thereby enabling the monitoring assembly 300 to detect environmental conditions at sea level in real time.
It should be noted that the temperature sensor 310, the wind speed sensor 320 and the air quality sensor 330 are all commercially available products, and the types thereof can be specifically set according to actual situations. In some embodiments of the present invention, the temperature sensor 310 is model WZP-291, the wind speed sensor 320 is model CYT-601, and the air quality sensor 330 is model AQH 01-10.
As shown in fig. 1 and 3, in some embodiments of the present invention, in order to facilitate real-time monitoring of the marine environment, a signal transmitter 400 is further disposed on the floating platform 200, and the signal transmitter 400 is electrically connected to the power management system 130, and the power management system 130 supplies power to the signal transmitter 400.
The signal transmitter 400 is an existing product, and the model thereof can be specifically selected according to actual conditions. In some embodiments of the present invention, signal transmitter 400 is model SCT-Q5.
By electrically connecting the monitoring assembly 300 to the signal transmitter 400. It can be understood that the temperature sensor 310, the wind speed sensor 320 and the air quality sensor 330 are respectively electrically connected to the signal transmitter 400, and the signal transmitter 400 is connected to the data management platform through signals, so that the detection data is transmitted to the signal transmitter 400 through the monitoring assembly 300, the detection data is transmitted to the data management platform through the signal transmitter 400, and the data on the sea is actually monitored through the data management platform, thereby realizing real-time monitoring of the marine environment change.
As shown in fig. 1 and 4, in some embodiments of the present invention, in order to improve the efficiency of the power generation apparatus for utilizing wave energy, the axis of the power generation pipe body 121 is perpendicular to the axis of the housing.
It should be noted that when the float 100 is at rest on the sea surface, the axis of the hull is perpendicular to the sea surface, while the axis is parallel to the sea surface. When the floating body 100 floats on the sea surface, under the action of sea water waves, the floating body 100 shakes on the sea surface, and the power generation tube body 121 synchronously shakes along with the shaking of the floating body 100, so that liquid in the power generation tube body 121 shakes in the power generation tube body, the friction area between the liquid in the power generation tube body 121 and the inner wall of the power generation tube body 121 is increased, and the power generation efficiency of the power generation tube body 121 is improved.
Specifically, when the center of gravity of the power generating tube body 121 is biased to the second conductive portion 123, the liquid in the power generating tube body 121 and the power generating tube body 121 rub against each other, electrons are easily obtained after the solid material rubs due to a triboelectric effect and electrostatic induction, a large amount of positive charges are accumulated on one side of the surface of the power generating tube body 121 close to the second conductive portion 123 due to the attraction of the electrons, a large amount of negative charges are accumulated on the first conductive portion 122, and at this time, a potential difference is generated between the first conductive portion 122 and the second conductive portion 123, so that the electrons on the first conductive portion 122 are driven to move from a high potential to a low potential, that is, the electrons on the first conductive portion 122 form a current flowing from the first conductive portion 122 to the second conductive portion 123 through the power management system.
When the power generation tube body 121 rotates to the horizontal position, the potential difference inside the power generation tube body 121 disappears, and at this time, no electrons are transferred to the surface of the power generation tube body 121.
When the center of gravity of the power generating tube 121 is shifted to the first conductive part 122, a large amount of positive charges are gathered on the side of the surface of the power generating tube 121 close to the first conductive part 122, and a large amount of negative charges are gathered on the second conductive part 123, so that a potential difference is generated between the first conductive part 122 and the second conductive part 123, and electrons on the second conductive part 123 are driven to move from a high potential to a low potential, that is, the electrons on the second conductive part 123 flow through the power management system to form a current flowing from the second conductive part 123 to the first conductive part 122. At this time, the power generation tube body 121 generating electricity through liquid-solid nano friction completes one period of oscillation, and forms one period of alternating current.
In some embodiments of the present invention, the micro control unit 140 is electrically connected to the signal transmitter 400, the micro control unit 140 is configured to store and process the detection data of the monitoring assembly 300, transmit the detection data to the signal transmitter 400, and transmit the detection data to the data management platform by the signal transmitter 400, so as to implement real-time monitoring of the environment at sea.
In addition, the micro control unit 140 can also control the output voltage of the power management system, thereby improving the working stability of the monitoring platform.
As shown in fig. 1, 2 and 4, in some embodiments of the present invention, in order to improve the utilization efficiency of the wave energy, the number of the power generation tubes 121 may be plural, and the number of the power generation tubes 121 may be any number greater than two, which may be set according to actual circumstances.
When the plurality of power generation tube bodies 121 are arranged in parallel, the first conductive parts 122 of two adjacent power generation tube bodies 121 are connected by a conductor, the second conductive parts 123 of two adjacent power generation tube bodies 121 are connected by a conductor, and the axes of the power generation tube bodies 121 are parallel to each other.

The balance body 150 is a counterweight of the floating body 100, and the material of the counterweight has a density greater than that of the sea water, so that the stability of the floating body 100 on the sea surface is improved by the counterweight, and the frequency of the floating body 100 on the sea surface is improved, thereby improving the utilization efficiency of the power generation tube 121 on the wave energy.
Specifically, the center of gravity of the balance body 150 is located on the axis of the housing 110, and the center of gravity of the floating body 100 is adjusted by the balance body 150, so that the axis of the floating body 100 is perpendicular to the horizontal plane after the floating body 100 stops swinging, thereby improving the stability of the floating body 100 on the sea surface.
