Description

Technical Field

[0001] The invention relates to the technical field of port measurement, in particular to a bottom bracket of a friction-generated sustainable wave measuring instrument. Background Art

[0002] In oceanography, waves are one of the most important and complex ocean hydrological elements. By measuring waves, we can obtain information about the elements of waves, which is crucial for ocean forecasting, marine engineering, disaster prevention and mitigation, marine rights protection, and navigation safety.

[0003] At present, wave measurement methods mainly include two categories: manual observation and instrument observation. Instrument observation is further divided into floating observation and bottom observation. Among them, bottom observation mainly uses sensors installed on the seabed or underwater to measure the pressure or sound wave changes caused by waves. These sensors can collect data in real time, and then analyze and process the collected wave data. Bottom observation has the advantages of not being affected by sea surface wind and waves, high measurement accuracy, and good concealment. In addition, bottom observation can also avoid erosion by sea surface pollutants and increase the service life of sensors; however, bottom observation also has some limitations. At present, the wave observation bottom bracket can only provide instrument support. The observation instrument needs to carry a heavier external power supply to complete the wave observation work with a longer time span.

[0004] When the external power supply fails or runs out of power, the instrument will stop observing. From a time perspective, for engineering and scientific research projects with a shorter construction period, the lack of data will delay the progress of subsequent work and cause delayed delivery of results. From a data quality perspective, missing data will cause discontinuous observation results, which will have a certain impact on the integrity of the data. At the same time, some special values ​​may be missed, which will affect the accuracy of statistics and calculations. From a project investment perspective, the missing measurement may be delayed in order to achieve a complete observation cycle, which will require additional observation and maintenance investment, resulting in unnecessary economic waste. From a safety perspective, the extension of observation time will inevitably increase the number and duration of the original maintenance, thereby increasing the probability of work hazards and placing higher demands on work safety. Summary of the invention

[0005] The present invention utilizes the mechanical energy of water flow and converts it into stable and safe electrical energy through the frictional power generation mechanical structure and power system on the bracket to charge an external power supply or directly power the instrument, thereby extending the battery life of the wave meter, reducing the frequency of maintenance and battery replacement, reducing the investment in observation costs and lowering the probability of maintenance risks.

[0006] Triboelectric Nanogenerator (TENG) is an energy harvesting device based on the triboelectric effect. The device uses the charge transfer phenomenon generated by two different materials when they come into contact and rub against each other to achieve the conversion of mechanical energy into electrical energy.

[0007] When two objects of different materials come into contact and rub against each other, electron transfer will occur due to the difference in electronegativity between them, causing the contact surface to be charged. This phenomenon is the triboelectric effect. During the friction process, electrons are transferred from one material to another, making one material positively charged and the other negatively charged. When the two materials are separated, an electric potential difference is formed between them. Charge flow and electrical energy output: In an external circuit, due to the existence of a potential difference, charges will flow, thereby forming an electric current and outputting electrical energy.

[0008] like Figure 6 As shown, the workflow is as follows:

[0009] 1. If the dielectric FEP (fluorinated ethylene propylene copolymer) and the electrode have no charge at the beginning, all static charges are generated by physical friction. The negative charge on the FEP surface is equal to the positive charge on the electrode surface. When the FEP completely overlaps with the first electrode, all positive charges in the circuit will be attracted to the upper surface of the first electrode, such as Figure 6 (I) as shown;

[0010] 2. When the FEP layer slides to the right, the positive charge in the circuit will flow from the left electrode to the right electrode through the load, such as Figure 6 (II) as shown;

[0011] 3. When the FEP coincides with the right electrode, all the positive charges will flow into the right electrode, e.g. Figure 6 (III) as shown;

[0012] Then, the FEP moves in the opposite direction from the right electrode to the left electrode, and the direction of movement is the same as the direction of positive charge movement. Thus, a closed circuit loop is formed, such as Figure 6 (IV) shown.

[0013] The present invention mainly utilizes the sliding independent layer mode friction nanogenerator technology, based on the triboelectric effect generated between two independent layers of dielectrics. The metal films on both sides of the dielectrics are not only used as friction materials for triboelectric charging, but also as electrodes. In order to maximize the triboelectric effect between the two layers, aluminum and perfluoroethylene propylene copolymer (FEP) with a large difference in friction polarity are selected as the friction layer, the aluminum film is used as the conductive layer, and the FEP is used as the independent layer.

[0036] The present invention is further described in detail below in conjunction with specific embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0037] like Figures 1 to 5 As shown, the present invention provides a friction power generation sustainable wave meter base support, comprising an instrument mounting bracket and at least one group of power generation units 7 located on the instrument mounting bracket, wherein the instrument mounting bracket is used to install the wave meter, and the power generation unit 7 is used to supply power to the wave meter on the instrument mounting bracket, and the power generation unit 7 comprises an upper outer cylinder 7-1, a lower outer cylinder 7-2, an inner rotating cylinder 7-4-1 and a plurality of outer cylinder connecting rods 7-3, an outer connecting ring 7-4 is provided on the outer wall of the inner rotating cylinder 7-4-1, and the outer connecting ring 7-4 divides the outer wall of the inner rotating cylinder 7-4-1 into an upper part and a lower part, wherein the axial length of the inner rotating cylinder 7-4-1 located at the upper part of the outer connecting ring 7-4 is greater than the axial length of the inner rotating cylinder 7-4-1 located at the lower part of the outer connecting ring 7-4, and the upper outer cylinder 7-1 is sleeved on the upper part of the inner rotating cylinder 7-4-1 and the lower outer cylinder 7- 2 is sleeved on the lower part of the inner rotating cylinder 7-4-1, and an upper waterproof bearing 7-7 and a lower waterproof bearing 7-8 are sleeved on the outer wall of the inner rotating cylinder 7-4-1. The upper waterproof bearing 7-7 and the lower waterproof bearing 7-8 are respectively located on both sides of the outer connecting ring 7-4, and the upper waterproof bearing 7-7 and the lower waterproof bearing 7-8 are respectively located in the upper outer cylinder 7-1 and the lower outer cylinder 7-2. The outer cylinder connecting rod 7-3 is a U-shaped structure, and the two ends of the outer cylinder connecting rod 7-3 are respectively connected to the upper outer cylinder 7-1 and the lower outer cylinder 7-2. A plurality of vertical axis fan blades 7-5 are evenly distributed in the outer cylinder connecting rod 7-3 and around the axis of the inner rotating cylinder 7-4-1. One side of the vertical axis fan blade 7-5 is connected to the outer connecting ring 7-4 and the external support bearing 7-6 located on the outer wall of the upper outer cylinder 7-1, and the cross section of the vertical axis fan blade 7-5 is an arc;

[0038] The inner wall of the upper outer cylinder 7-1 is provided with four internal electrodes 7-9 evenly distributed around the axis of the upper outer cylinder 7-1, and there is a gap of 1 mm between adjacent internal electrodes 7-9. Two opposite internal electrodes 7-9 are connected by a wire 7-11 to form an electrode group. The outer wall of the inner rotating cylinder 7-4-1 located inside the upper outer cylinder 7-1 is provided with two oppositely arranged dielectrics 7-10. The width of a single dielectric 7-10 is the same as that of a single internal electrode 7-9. The inner wall of the internal electrode 7-9 is in contact with the outer wall of the dielectric 7-10. There is an insulating layer between the upper outer cylinder 7-1 and the internal electrode 7-9, and between the inner rotating cylinder 7-4-1 and the dielectric 7-10.

[0039] The internal electrode 7-9 is an aluminum foil film, and the dielectric 7-10 is a perfluoroethylene propylene copolymer (FEP).

[0040] The instrument mounting bracket has a waterproof power interface 5, and the two electrode groups are connected to the bridge rectifier to output DC power (such as Figure 8 ), the DC power supply can charge the rechargeable battery, the rechargeable battery is connected to the waterproof power interface 5, and after the waterproof power interface 5 is connected to the power line of the wave meter, the wave meter can be powered by the power generation unit 7.

[0041] When the vertical shaft fan blade 7-5 in the power generation unit 7 is driven by the fluid to rotate, it drives the inner drum 7-4-1 to rotate. At the same time, the dielectric 7-10 and the internal electrode 7-9 rub against each other, generating electron transfer and forming current. The working process and principle are shown in Figure 7 As shown:

[0042] (1) The dielectric 7-10 and the internal electrode 7-9 are in a completely overlapping position. Because the friction polarity of the dielectric 7-10 (FEP) is very different from that of the internal electrode 7-9 (aluminum), when the surfaces are in contact and friction, negative charges will accumulate on the surface of the dielectric 7-10, while positive charges will accumulate on the surface of the internal electrode 7-9. The amount of positive and negative charges is equal, and this state is in an electrostatic equilibrium state, so there is no charge transfer between the two;

[0043] (2) When the dielectric 7-10 starts to rotate, it gradually slides from the overlapping position of one electrode group to the other electrode group. In this state, a potential difference is generated, causing positive charges to flow from one electrode group to the other electrode group along the sliding direction, thereby forming an instantaneous current on the external load;

[0044] (3) When the dielectric 7-10 overlaps with another electrode group, all charges are transferred to the other electrode group, achieving another electrostatic equilibrium state;

[0045] (4) When the dielectric 7-10 continues to rotate, the positive charge will be attracted to flow back to the electrode group, providing a reverse current in the circuit, thus generating a repetitive power generation process.

[0046] like Figure 1 , Fig. 9 , Fig.10 As shown, this embodiment sets three groups of power generation units 7, which are connected in parallel with the power management system through wires. The electric energy generated by the power generation unit 7 reaches the power management system through the transmission wire 7-11, and is charged to the rechargeable battery with a stable voltage and current through the action of rectifiers, voltage stabilizers, capacitors and other components. At the same time, the battery status is monitored to prevent the battery from being overcharged and protect the battery health. The parallel power generation structure improves the reliability of power supply. When a power generation unit 7 fails, it will not hinder the power supply function of other power generation units 7, and electric energy can still be supplied continuously, which improves the fault tolerance of the power generation system; at the same time, the friction nanogenerator has the characteristics of high voltage and low current. After parallel connection, the voltage will not be too high, which reduces the difficulty of voltage stabilization and ensures the safe operation of the circuit system.

[0047] According to the structure and connection method of the wave observation instrument power supply, you can choose to use both external batteries and rechargeable batteries to power the instrument, or use rechargeable batteries to charge the external battery of the instrument. Since the water body is constantly flowing, the power will be continuously supplied to achieve the purpose of increasing the endurance of the observation instrument.

[0048] like Figure 1 As shown, the instrument mounting bracket includes a probe guard ring 1, a probe tray 3, upper connecting rods 6 equal to the number of power generation units 7, lower connecting rods 8 and inclined tubes 4 equal to the number of power generation units 7, adjacent power generation units 7 are connected by upper connecting rods 6 and lower connecting rods 8, the inclined tubes 4 are evenly distributed around the probe guard ring 1 axially, one end of the inclined tube 4 is connected to the top of the upper outer tube 7-1 in the power generation unit 7, and the other end is fixed to the outer wall of the probe guard ring 1, the probe tray 3 is located below the probe guard ring 1, the probe tray 3 is connected to the probe guard ring 1 by a tray rod 2, and the lower part of the power generation unit 7 has a supporting chassis 9. The upper connecting rod 6 and the inclined tube 4 are both tubular structures, the upper connecting rod 6, the inclined tube 4 and the upper outer tube 7-1 in the power generation unit 7 are all connected to each other, and the power management system is located inside the tube body of the instrument mounting bracket.

[0049] On the basis of the original instrument support function, the present invention adds the function of hydrodynamic charging, which is similar to the charging electronic device of smart wearable, and is upgraded to a mechanical energy charging device. Since the movement of the outside world is inevitable, the energy will be stored and supplied continuously. The source of electric energy is mainly from two ways: mechanical energy drives metal to cut magnetic flux lines to form electric energy and solar energy is converted into electric energy. Since the wave observation instrument is equipped with a magnetic compass, the proximity of magnetic materials will cause the magnetic compass to deviate, resulting in numerical errors in wave direction observation. The way that the wave meter sits on the bottom bracket and observes on the bottom makes the instrument and the bracket unable to receive sunlight. The friction nanogenerator technology can effectively solve the above problems. Since it is the basic principle of frictional electricity generation, the kinetic energy of water in the ocean is endless, so it can provide a relatively stable mechanical energy input; at the same time, the frictional electricity generation material does not need to use magnetic materials, so it will not affect the normal operation of the instrument magnetic compass, and the accuracy of the observation results can be guaranteed. The production of the present invention can provide a relatively stable and continuous electric energy for the observation instrument, ensuring that the instrument will not have observation problems due to energy factors, thereby solving a series of influences and losses caused by power supply problems of the instrument.

[0050] The probe guard ring 1 in the base support of the friction power generation sustainable wave meter of the present invention is surrounded by a cylindrical tube structure by a rectangular plate of 304 stainless steel (non-magnetic, the stainless steel material described below is uniformly 304 stainless steel), which is used to protect the instrument probe from being bumped, and at the same time, it is used as a connecting structure of the instrument mounting bracket and is welded and connected to the tilting tube 4; the tray rod 2 is made of a stainless steel solid rod, which is used to connect the probe guard ring 1 and the probe tray 3; the probe tray 3 is a stainless steel disc, and holes are punched on the disc according to the probe fixing hole position to fix the instrument probe, so that the instrument probe and the bracket are connected as one; the tilting tube 4 is made of a stainless steel hollow tube, the upper part is connected to the probe guard ring 1, and the lower part is connected to the upper connecting rod 6 and the power generation unit 7, and the internal cavities of the tilting tube 4, the upper connecting rod 6 and the power generation unit 7 are interconnected, so as to connect the wires to form a line structure. The main function is to enlarge the branch span of the instrument mounting bracket and provide stable support for the instrument; at the same time, a rechargeable battery and a power management system are filled in the tube to power the observation instrument or charge the external battery of the instrument.

[0051] The power transmission unit is composed of a rechargeable battery, a power management system and a waterproof power interface 5. The rechargeable battery and the power management system are located in the tilt tube 4. The electric energy generated by the power generation unit 7 reaches the power management system through the transmission wires 7-11. After the action of the rectifier, the voltage stabilizer, the capacitor and other components, the rechargeable battery is charged with a stable voltage and current. At the same time, the battery condition is monitored to prevent the battery from being overcharged and to protect the battery health. The waterproof power interface 5 is placed on the outside of the tilt tube 4 and is connected to the tilt tube 4 with a waterproof structure. The waterproof power interface 5 is made of non-magnetic material and adopts a plug structure and a waterproof mechanism that match the instrument power connection port. According to the connection method and structure of the instrument power supply, the external power charging mode or the direct power supply mode for the instrument is selected. Both connection modes reduce the external power loss, thereby effectively extending the observation time limit. The interface can be sealed when not in use.

[0052] The upper connecting rod 6 is made of a stainless steel hollow tube, and its two ends are respectively connected to the branched inclined tube 4 and the power generation unit 7, so as to reinforce and connect the branch structure of the bracket, and at the same time, the internal cavities are interconnected to connect the charging line; the power generation unit 7 is the power generation structure of the bracket, and the interior is composed of non-magnetic materials to achieve the purpose of power generation, wherein the top of the upper outer cylinder 7-1 is connected to the upper connecting rod 6 and the inclined tube 4, and the inner cavities are interconnected; the lower outer cylinder 7-2 is connected to the lower connecting rod 8; the bottom of the lower outer cylinder 7-2 is connected to the supporting chassis 9; the lower connecting rod 8 is composed of a solid stainless steel rod, and its two ends are respectively connected to the lower outer cylinder 7-2 of the power generation unit 7, so as to connect the power generation unit 7, and form a whole with the instrument mounting bracket to increase the stability and strength of the bracket;

[0053] The supporting chassis 9 is composed of a stainless steel disc, which is respectively connected to the bottom of the power generation unit 7 to enhance the stability of the support on the bottom. At the same time, when the seabed is silt or sand, it plays the purpose of preventing the support from sinking.

[0054] The upper outer tube 7-1 is made of a stainless steel hollow tube, the top of which is connected to the inclined tube 4 and the upper connecting rod 6, and the inner cavity is connected, and the transmission wire 7-11 can be inserted to form a charging line structure; the lower outer tube 7-2 is made of a stainless steel hollow tube, the lower part is connected to the lower connecting rod 8; the bottom is connected to the supporting chassis 9;

[0055] The outer cylinder connecting rod 7-3 is made of a stainless steel rod. Since the inner cylinder 7-4-1 needs to rotate freely, the upper outer cylinder 7-1 and the lower outer cylinder 7-2 are not connected. The outer cylinder connecting rod 7-3 is needed to connect the two into a whole. While ensuring that the inner cylinder 7-4-1 can rotate freely, it also ensures the overall strength of the instrument mounting bracket. The width of the outer cylinder connecting rod 7-3 should be greater than the width of the vertical axis fan blade 7-5, and the length should also include the vertical axis fan blade 7-5 within the upper and lower edges of the outer cylinder connecting rod 7-3 to prevent obstruction of the free rotation of the vertical axis fan blade 7-5. The outer cylinder connecting rod 7-3 can be evenly distributed in 4 to 6 pieces around the outer cylinder, connecting the upper outer cylinder 7-1 and the lower outer cylinder 7-2. While ensuring the integrity of the instrument mounting bracket, it also ensures that the water can freely pass through the outer cylinder connecting rod 7-3 to push the vertical axis fan blade 7-5 to rotate;

[0056] The inner drum 7-4-1 is made of a lightweight, high-strength non-magnetic material, and the overall structure consists of a coaxial short cylinder, an outer connecting ring 7-4 and a long cylinder. The short cylindrical part plays the role of the inner ring of the lower waterproof bearing 7-8 and can rotate freely; the circular cross-sectional radius of the outer connecting ring 7-4 is larger than the radius of the inner drum 7-4-1, and the outer side is connected to the vertical axis fan blade 7-5. When the vertical axis fan blade 7-5 is pushed by the water body to rotate, the inner drum 7-4-1 rotates synchronously; the long cylindrical part plays the role of the inner ring of the upper waterproof bearing 7-7 and can rotate freely. At the same time, the dielectric 7-10 on the inner drum 7-4-1 is attached to the inner drum 7-4-1. The radius length of the inner drum 7-4-1 can ensure that the dielectric 10 and the internal electrode 7-9 rub against each other, and cannot completely prevent the inner drum 7-4-1 from rotating. When the inner drum 7-4-1 rotates, the dielectric 7-10 and the internal electrode 7-9 are driven to rub against each other, thereby achieving the purpose of power generation;

[0057] The vertical axis fan blade 7-5 is made of a lightweight, high-strength non-magnetic material. Depending on the situation, 4 to 6 blades can be evenly distributed around the inner drum 7-4-1. The upper part is connected to the external support bearing 7-6, and the lower part is connected to the external connection ring 7-4. Taking advantage of the uneven force characteristics generated by its structure, when there is a moving fluid in the environment, since the cross-section of the vertical axis fan blade 7-5 is an arc, the fluid will generate a directional thrust on the vertical axis fan blade 7-5, causing it to rotate, thereby driving the inner drum 7-4-1 connected to it to rotate together, playing the role of receiving mechanical energy in the water body; the external support bearing 7-6 is made of non-magnetic material and connected to the upper part of the vertical axis fan blade 7-5, so that the upper and lower parts of the vertical axis fan blade 7-5 have force points, which plays a role in reinforcing the vertical axis fan blade 7-5 and preventing the vertical axis fan blade 7-5 from being seriously deformed or damaged due to the large force;

[0058] The upper waterproof bearing 7-7 adopts a waterproof bearing structure, and the material is made of 304 stainless steel or ceramic material. Its outer ring directly uses a part of the inner wall of the upper outer cylinder 7-1, and the inner ring is a part of the long cylinder of the inner rotating cylinder 7-4-1. While ensuring that the power generation unit 7 is not flooded, it can also ensure that the inner rotating cylinder 7-4-1 can rotate freely;

[0059] The lower waterproof bearing 7-8 adopts a waterproof bearing structure, and the material is made of 304 stainless steel or ceramic material. The outer ring directly uses a part of the inner wall of the lower outer cylinder 7-2, and its inner ring is a part of the short cylinder of the inner rotating cylinder 7-4-1, ensuring that the inner rotating cylinder 7-4-1 is stably located between the upper and lower outer cylinders and rotates freely;

[0060] The internal electrode 7-9 uses an aluminum film as a conductive layer and is connected to the inner wall of the upper outer cylinder 7-1 by an insulator. Four internal electrodes 7-9 of equal width and length are evenly distributed on the inner wall of the upper outer cylinder 7-1, and adjacent internal electrodes 7-9 maintain a spacing of 1 mm. Two opposing internal electrodes 7-9 are connected by a wire 7-11 to form an electrode group, so that the four internal electrodes 7-9 form two electrode groups, which are similar to a grid-like electrode structure.

[0061] The dielectric 7-10 uses a perfluoroethylene-propylene copolymer (FEP) as a friction layer, and is connected to the long cylindrical part of the inner drum 7-4-1 by an insulator. Two pieces of FEP are in contact with two opposite internal electrodes 7-9 respectively, and the width is equal to the internal electrode 7-9, and the length is slightly shorter than the internal electrode 7-9, so as to ensure that the dielectric 7-10 and the internal electrode 7-9 can generate complete friction. When the inner drum 7-4-1 drives the dielectric 7-10 to rotate, the dielectric 7-10 will rotate from one electrode group to another electrode group by friction, and repeat over and over again, forming a continuous power generation effect, thereby achieving the purpose of converting mechanical energy into electrical energy;

[0062] The transmission wire 7-11 is made of non-magnetic wire, which is connected to the internal electrode 7-9, providing a channel for the current to be transmitted and collected outward, so that the current can be rectified, stabilized and stabilized to achieve the purpose of storage or use.

[0063] The present invention belongs to green low-carbon energy technology, is environmentally friendly and pollution-free, utilizes the energy of the water flow field in the ocean to convert into electrical energy, and provides endurance energy for observation instruments; applies the smart wearable self-powered technology to the ocean observation technology, upgrades the observation instrument bracket, and achieves the function of providing energy supply for the observation instrument, which can be regarded as an underwater "power bank" for wave measuring instruments; utilizes the nano friction generator technology, effectively avoids the interference of magnetic materials on wave direction observation in cutting magnetic flux lines for power generation (affecting the magnetic compass), and also avoids the technical difficulties of solar power generation during bottom observation, and solves the problem of underwater electricity generation; integrates and innovates the "conductor-dielectric working principle under contact sliding mode" and "grid electrode structure" in the friction nano generator, forms a rotating friction electricity generation mode, achieves the circulation mechanism of reciprocating friction between electrodes and dielectrics, and makes the way of collecting external flow field mechanical energy more diversified. The power generation units are connected in parallel, which improves the reliability of power supply. When a power generation unit fails, it does not affect other power generation units to continue to provide power to the battery.

[0064] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
