Description
Technical Field
The invention belongs to the field of power generation of rescue equipment, and relates to a water surface floating power generation device.
Background
When the life jacket is used for taking a passenger on a sea-air line vehicle such as a passenger ship, a yacht, an airplane and the like, the life jacket is basic safety equipment for accidents such as falling to the sea and the like. When a marine disaster occurs, the life jacket can help marine victims float on the water surface for a long time, so that the marine victims are prevented from drowning, and the waiting rescue time is prolonged.
In order to increase the chance of rescuing for the marine victims, the traditional life jacket mostly utilizes bright yellow or orange as the ground color, and is matched with a reflective strip or a light-emitting bulb and is additionally provided with a whistle and a reflective mirror, so that the marine victims can show the appearance and make a sound in the sea to be rapidly discovered.
However, the above functions still have disadvantages because of the bright yellow or orange background color, the reflective strips, the mirror cannot be used at night and the whistle sound transmission distance is not long. And because the airplane can not carry a common lithium battery, the light-emitting bulb is usually stored by using a solar panel, but the problem of insufficient electric quantity still exists.
The "black box" is one of the electronic recording devices specific to modern aircraft. There are two black boxes, a Cockpit Voice Recorder (Cockpit Voice Recorder) and a Flight Data Recorder (Flight Data Recorder). The mechanical parts and the electronic instruments of the airplane are provided with sensors which are connected with the mechanical parts and the electronic instruments. The method can record the voice conversation of half an hour before the airplane stops working or crashes, the flight height, the speed, the course, the climbing rate, the descending rate, the acceleration condition, the oil consumption, the landing gear releasing and receiving, the Greenwich mean time, the working condition of an airplane system, the working parameters of an engine and other flight parameters of two hours, and decode the recorded contents as required for flight experiments and accident analysis. The black box has a thick steel plate and a plurality of layers of heat-insulating, impact-resistant and pressure-resistant protective materials, and is usually arranged at the safest part at the tail of an airplane. The recording medium has also been improved from a tape type to a static memory recorder capable of withstanding greater impacts, similar to the memory chip in a computer, to prevent the black box from being damaged in the air. However, the black box requires the storage battery to supply power continuously, and once the storage battery is low in power, the black box cannot exert the function. For example, a horsemanship event, where no airplane debris is found, is because the rescuer does not find his/her location during the time the battery powers the black box, and after the battery runs out of charge, the black box has no way to continue to signal, resulting in a horsemanship event as a mystery. If the black box is powered on all the time, there is enough time to locate the debris of the airplane and thus perform rescue work. The invention can supply power by itself, and if the black box is arranged on the black box, the tragedy can be reduced.
One of the existing solar water life saving devices comprises a conventional water life saving floating body, wherein a solar battery, an electric storage device, a switch and a distress signal generator are arranged on the life saving floating body, the solar battery is arranged at a position on the life saving floating body, which is easy to receive sunlight irradiation, the switch is arranged at a position which is easy to operate by a human hand, and the solar battery, the electric storage device, the switch and the distress signal generator are connected into a loop through electric wires. The distress signal generator of the device can be designed to send out distress sounds, various colors of lamplight or specific distress signals such as radio waves, sound waves, light waves and the like according to requirements, so that accurate position information is provided for rescuers, the rescuers can conveniently capture the distress signals, and the rescue efficiency is improved. At ordinary times, the solar cell is arranged at a position where sunlight is easy to irradiate so as to store energy, the switch is turned on when a person is in distress, the signal generator can work day and night, and meanwhile, the solar cell continuously supplements electric energy until the person in distress is rescued, and the distress operation is very convenient.
The traditional hydroelectric generator consists of main components such as a rotor, a stator, a frame, a thrust bearing, a guide bearing, a cooler, a brake and the like. The stator mainly comprises a base, an iron core, a winding and other components. The stator core is made up of cold-rolled silicon steel sheets by laminating, and can be made into integral and split structure according to the condition of manufacture and transportation. The working principle is as follows: water flow impacts a rotating wheel of the hydroelectric generator to enable the rotating wheel to rotate, the main shaft drives a generator rotor to rotate, direct current is introduced into a coil of the generator rotor, a rotating magnetic field is generated by the rotor coil, magnetic lines of force are cut by stator coils in a rotating process, voltage is generated in the stator coils according to the electromagnetic induction principle, and the stator coils generate current after being connected into a load. The water energy is converted into mechanical energy, and the rotating shaft of the hydroelectric generator drives the rotor of the generator to convert the mechanical energy into electric energy for output.
The black box is essentially a transceiver. During the flying process of the airplane, the system can timely receive various information collected by the built-in sensors and automatically convert the information into corresponding digital signals to be continuously recorded; when the airplane crashes, the emergency positioning transmitter of the black box automatically transmits radio signals with specific frequency and regularity similar to heartbeat to all directions to 'announce' the position of the airplane, so that a searcher can trace waves to search. Because of the limited capacity of the battery in the cartridge, the positioning transmitters are typically only continuously operated for months. Therefore, the black box normally uses an external power supply of the airplane, and the required direct current is supplied by a power generation system of the airplane. The generator is an AC/DC converter, and the generated AC is directly converted into DC by a DC motor. And once the generator fails, the power supply is automatically switched to be supplied by the storage battery to provide the required voltage.
The life jacket with the solar water life-saving device has the undesirable characteristics of heaviness, sultriness and the like. Because the light bulb utilizes the solar panel to store electricity, the requirements for environmental factors and geographic factors are high, and effective help is difficult to provide in continuous dark weather.
The wave energy collecting equipment of the electromagnetic induction generator is generally large in size and heavy in weight, so that large-scale integration is difficult. Furthermore, such wave energy harvesting devices require additional external units to capture the external mechanical energy, further increasing the complexity and manufacturing cost of the generator. In consideration of the geographical environment, the practical difficulty of the traditional wave power generator is increased by the wave resource characteristics of short period, small wave height and low energy current density in offshore land.
Because the storage battery of the black box has limited electric quantity storage, the positioning transmitter can only continuously work for months, and if the electric quantity is used up after a long time, the positioning transmitter cannot continuously send signals. The best opportunity for rescue is missed.

The wall thickness of both hemispheres is 2 mm. At the bottom of the hollow hemisphere with the complete surface, there is a semicircular ring with a diameter of 5mm, a plumb bob 6 is connected to the lower part of the semicircular ring, the plumb bob 6 is not connected to the hemisphere with the wire guide hole, but connected to the other hemisphere opposite to the hemisphere, in order that the wire is connected to the signal emitting device, and the plumb bob 6 functions to increase the weight of the ball, so that it can be positioned in the wave at any time, in order to avoid the wire contacting with the plumb bob 6, and the wire can be connected to the signal emitting device more safely, therefore, the wire guide hole and the plumb bob 6 are arranged opposite to each other in different hemispheres. The inner surface of the hollow large ball 4 is plated with a gold layer firstly to be used as an electrode, the ZnO nano-rod grows on the metal electrode by using a hydrothermal method, and an organic polymer PDMS7 is used to wrap, polymerize and grow outside the nano-ZnO array 8 to form protective wrapping on the friction material. The flexibility of the nano ZnO array 8 is improved. And etching the PDMS to expose the tips of the ZnO nanorods by adopting a low-temperature radio frequency plasma etching technology. When the ZnO nano-rod rubs with the friction material with negative electricity, the ZnO nano-rod generates negative induction charge.
Hollow pellets 1: is formed by splicing two hollow hemispheres with the diameter of 4cm, and the thickness of the sphere wall is 5 mm. The outer surface of the hollow ball 1 is plated with a gold layer to be used as an electrode, and PET3 is attached to the gold layer to be used as a friction material. PET3 produces a positive induced charge when rubbed against a positively charged friction material.
The hollow pellets 1 are placed in the hollow balloon 4 and connected by nylon connecting strings 9 so that the bottom area of the hollow pellets 1 and the inner surface area of the bottom of the hollow balloon 4 are in contact. One end of a nylon connecting rope 9 is clamped and fixed by a hollow small ball 1, the other end of the nylon connecting rope is stuck on the ball wall near a wire hole of a hollow big ball 4, an electrode of the hollow small ball 1 is pulled out by the wire winding nylon connecting rope 9, and an electrode of the hollow big ball 4 is pulled out by the wire winding nylon connecting rope 9 from the inner surface through the hole of the nylon connecting rope 9.

And etching the PDMS to expose the tips of the ZnO nanorods by adopting a low-temperature radio frequency plasma etching technology. The surface of the nano friction material needs to be modified and the performance of the nano friction material needs to be improved, which is a key for determining the amount of generated friction electricity and a key for improving the energy conversion rate. The nano ZnO array can be effectively protected based on the research of the growth and etching technology of the nano ZnO array flexible protection layer material, the friction area is increased, the friction surface charge is increased, and the conversion electric quantity is increased. And an organic polymer PDMS7 which is good in flexibility, easy to polymerize and good in insulating property is selected to wrap, polymerize and grow outside the nano ZnO array, so that a protective wrapping is formed on the friction material. The organic material with better flexibility effect is selected to carry out surface modification and protection on the ZnO nanorod array, so that the toughness and the friction efficiency of the ZnO nanorod array are improved.
