DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The purpose of the present invention is to provide an all-weather energy collection system to solve the problems existing in the above-mentioned prior art and to collect ambient energy efficiently and stably around the clock.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Wireless Sensor Network (WSN) is a network system composed of a large number of distributed nodes. Various low-power sensors in the nodes can exchange and transmit data through wireless communication protocols to achieve monitoring, feedback and control of the environment, objects or events. With its unique advantages and broad application prospects, WSN has great application potential in environmental monitoring, smart agriculture, industrial automation, health monitoring and intelligent transportation. At present, WSN mainly uses chemical batteries to power the nodes of the network system. Although chemical batteries have the advantages of wide applicability, small size and high energy density, they have the disadvantages of limited life, frequent manual replacement and high cost of scrapping, which greatly restricts the further development and promotion of WSN and related technologies.

[0025] The emergence of environmental energy recovery technology has brought great hope for solving the above problems. This technology mainly collects and utilizes energy from the environment to power the above sensors. However, the types of energy recovery from the natural environment known to the inventors are different, mainly photovoltaic power generation, wind power generation, hydropower generation, etc., which can only recycle a single energy source in the natural environment and cannot fully adapt to weather changes in the natural environment. Therefore, it cannot provide continuous and stable energy supply, that is, it cannot achieve all-weather energy collection.

[0026] In order to solve this problem, fully adapt to weather changes in the natural environment, and realize all-weather energy collection, the present invention provides an all-weather energy collection system, such as Figure 1 to Figure 12 As shown, it includes a support frame 4 made of aluminum profiles, which is used to provide stable connection and support for the structures of each unit of the system; a rainwater collection unit 1 is arranged on the top of the support frame 4, and a siphon mechanism is arranged therein, and a nozzle 15 is connected to the bottom of the siphon mechanism through a drainage pipe 14, which can spray rainwater collected to a set height from the nozzle 15, so that the rainwater collection unit 1 can convert the collected disordered, random, low-energy-level raindrop energy into orderly, stable, high-energy-level quantitative rainwater potential energy; a wind-rain energy power generation unit 2 is arranged in the middle of the support frame 4, which can realize rotational power generation under the impact of wind force and / or water flow sprayed from the nozzle 15; a solar power generation unit 3 is arranged on the support frame 4, and can convert solar energy into electrical energy. The present invention is based on the coordinated cooperation of a rainwater collection unit 1, a wind and rain energy power generation unit 2 and a solar power generation unit 3, which can realize the coordinated collection of three natural environmental energies of wind, rain and light in the environment, and can effectively improve the system integration level and comprehensive power generation capacity of the all-weather energy collection system. The generated electric energy is transmitted to the battery through a wire. This process is a mature and known solution and will not be elaborated on. Relying on the battery to provide continuous and stable electric energy for the low-power devices of the nodes of the wireless environmental sensor network is beneficial to the application scenario range of the all-weather energy collection system, and effectively expands the networking range and node quantity scale of the wireless environmental sensor network.

[0027] The rainwater collection unit 1 of the present embodiment includes a rain tray 11 with an opening at the top. The upper surface of the rain tray 11 is an inverted trapezoidal structure with a hole at the center bottom. The inverted trapezoidal structure can drain rainwater falling on the top to the center opening. A filter tube 12 is connected below the center hole. A siphon cup 13 is located directly below the filter tube 12. Water flows through the filter tube 12 and accumulates in the siphon cup 13. Two siphon mechanisms are fixedly arranged in the siphon cup 13. The siphon mechanism includes an inlet pipe section 132 and an outlet pipe section 131. The inlet pipe section 132 is vertically fixed to the bottom of the siphon cup 13. The lower part of the inlet pipe section 132 is connected to the inside of the siphon cup 13, and the top of the inlet pipe section 132 is closed. The outlet pipe section 131 is coaxially arranged in the inlet pipe section 132, and the bottom of the outlet pipe section 131 passes through the bottom of the siphon cup 13. After that, it is connected with the drainage pipe 14, and the top of the outlet pipe section 131 is fixedly sealed and connected to the top of the inlet pipe section 132, and an opening connected to the inside of the inlet pipe section 132 is provided at the connection position; when the water level in the siphon cup 13 increases to a preset specific height, the water level completely submerges the opening connected to the top of the outlet pipe section 131 and the inlet pipe section 132, and the siphon emptying event is triggered at this time, so that the rainwater accumulated in the siphon cup 13 quickly flows into the drainage pipe 14 through the outlet at the bottom of the outlet pipe section 131, and a high-speed water jet is formed at the nozzle 15 at the end of the drainage pipe 14 to impact the water wheel 22 in the wind and rain energy power generation unit 2, so that it drives the transmission shaft 24 to rotate, and the conversion of fluid energy into mechanical energy is carried out by the way that the water flow directly impacts the water wheel 22, which can effectively reduce the energy conversion loss.

[0028] In order to be able to control the stopping of the siphon drainage process, in one embodiment, a ventilation pipe section 133 is designed, one end of the ventilation pipe section 133 is fixedly and sealedly connected to the bottom of the siphon cup 13, and the other end passes through the top of the water inlet pipe section 132, and is connected to the inside of the water outlet pipe section 131 through a starting block with a connecting port; an air hole is provided on the side wall of the ventilation pipe section 133 near the bottom of the siphon cup 13. In this embodiment, the siphon mechanism can be designed with a corresponding height according to the total amount of rainwater that the siphon cup 13 needs to store, that is, the water level reaches the siphon start position 134 that triggers the siphon emptying event. In this embodiment, the siphon start position 134 is when the water level completely submerges the opening at the top of the outlet pipe section 131 that is connected to the inlet pipe section 132; the air hole provided at the bottom end of the vent pipe section 133 or at the side wall of the vent pipe section 133 at the designed height can be used as the siphon stop position 135 for closing the siphon emptying event. In this embodiment, the water level in the siphon cup 13 is lowered to expose the air hole in the vent pipe section 133 as the siphon stop position 135; when the water level in the siphon cup 13 reaches When the siphon start position 134 of the siphon emptying event is triggered, rainwater flows from the water inlet pipe section 132 to the water outlet pipe section 131. Since the water flow fills the two pipe sections and the water flow is continuous, there is a pressure difference between the free liquid surface in the siphon cup 13 and the liquid surface at the end of the siphon pipe outlet section 131. The pressure difference will continue to push the rainwater in the siphon cup 13 into the siphon pipe to form a continuous siphon phenomenon until the water level gradually drops to the siphon stop position 135 that closes the siphon emptying event. At this time, air enters the ventilation pipe section 133 through the air hole, and then enters the connection between the water inlet pipe section 132 and the water outlet pipe section 131 through the ventilation pipe section 133, breaking the continuity of the water flow and forcing the siphon event to end.

[0029] In a specific embodiment, the wind and rain energy power generation unit 2 includes a wind scoop 21, a water wheel 22 and a friction nano generator 25. The rotor 251 of the friction nano generator 25 is fixedly connected to the transmission shaft 24. The wind scoop 21 is fixedly sleeved on the top of the transmission shaft 24. The fan blade configuration of the wind scoop 21 is selected as a lift-type vertical axis fan blade. This configuration can achieve high rotation speed at rated wind speed, and thus has the characteristics of high wind energy utilization rate; in addition, the vertical axis working mode of the wind scoop 21 can not only realize the capture of wind energy in all wind directions, but also enhance the stability of the system; a water wheel 22 is fixedly sleeved in the middle of the transmission shaft 24, and two nozzles 15 arranged at an angle to the water wheel 22 are provided on the outside of the water wheel 22, and the nozzles 15 are parallel to the tangent direction of the water wheel 22, so as to increase the impact force of the water flow on the water wheel 22; the water wheel 22 adopts a Pelton water wheel 22, which has a simple and efficient structure, and uses the method of water flow directly impacting the water bucket to convert fluid energy into mechanical energy, which can effectively reduce energy conversion losses. On this basis, the coaxial design of the wind scoop 21 and the water wheel 22, as well as the power generation scheme of sharing the same friction nanogenerator 25, make the system structure more compact, significantly improve the space utilization, and greatly enhance the system's integration capabilities.

[0030] In order to prevent the rainwater from corroding the friction nanogenerator 25 after impacting the water wheel 22, in a preferred embodiment, a water accumulation plate is fixedly provided at the bottom of the water wheel 22, and the water accumulation plate is fixedly sleeved on the transmission shaft 24. A cylindrical water wheel baffle 23 is sealed on the water accumulation plate. The water wheel 22 and the nozzle 15 are both located in the water wheel baffle 23. A drainage groove is provided on the water accumulation plate to receive the water sprayed from the nozzle 15 and drain it to the outside through the drainage groove.

[0031] The friction nanogenerator 25 of this embodiment includes a rotor 251 and a stator 252. The rotor 251 includes a rotating bracket 2511. The outer side of the rotating bracket 2511 is ringed with a fluorinated ethylene propylene film 2512, and one end of the rotating bracket 2511 is fixedly connected to the transmission shaft 24. The stator 252 includes a cylindrical shell 2522. The inner wall of the cylindrical shell 2522 is ringed with a plurality of copper foils 2521 at equal intervals, and the number of copper foils 2521 is twice the number of fluorinated ethylene propylene films 2512. The plurality of copper foils 2521 are formed into the same number of first copper electrodes 25211 and second copper electrodes 25212, and a second copper electrode is arranged between every two adjacent first copper electrodes 25211. Fig.12 , the diagram shows the charge transfer principle of the friction nanogenerator 25. I is the current, R It is a known structure such as a resistor, a battery, or an electrical load; when there is an external excitation, the rotor 251 is driven to rotate through the transmission shaft 24, and the fluorinated ethylene propylene film 2512 on the rotor 251 and the copper foil 2521 on the stator 252 generate friction, thereby generating current. When working, the wind scoop 21 and the water wheel 22 drive the rotor 251 of the coaxial friction nanogenerator 25 to rotate, so that the fluorinated ethylene propylene film 2512 on the rotor 251 and the copper foil 2521 inside the stator 252 rub to transfer charge. The fluorinated ethylene propylene film 2512 is initially in contact with the first copper electrode 25211. At this time, the fluorinated ethylene propylene film 2512 has a negative charge due to its inherent charge characteristics, while the first copper electrode 25211 has a positive charge. This charge configuration establishes an initial electrostatic field in the system. As the fluorinated ethylene propylene film 2512 begins to slide under the push of the water flow, it moves toward the second copper electrode 25212. In this process, the fluorinated ethylene propylene film 2512 slides from the positive charge region of the first copper electrode 25211 to the second copper electrode 25212. The second copper electrode 25212 initially maintains a charge separation state with the first copper electrode 25211, that is, the second copper electrode 25212 is negatively charged. Due to the movement of the fluorinated ethylene propylene film 2512, the electrostatic balance previously established with the first copper electrode 25211 is broken, resulting in a significant potential difference between the two electrodes. This potential difference causes the current to flow from the first copper electrode 25211 to the second copper electrode 25212, realizing dynamic energy conversion.

[0032] When the fluorinated ethylene propylene film 2512 continues to move and eventually completely overlaps with the second copper electrode 25212, the charges in the system are redistributed again to reach a new electrostatic equilibrium state. At this position, the charges of the first copper electrode 25211 and the second copper electrode 25212 are effectively transferred and rebalanced through the fluorinated ethylene propylene film 2512. As the fluorinated ethylene propylene film 2512 continues to rotate, separates from the second copper electrode 25212 and begins to return to the first copper electrode 25211, the electrostatic equilibrium state is once again destroyed. This rapid charge change and movement generates an induced current, which is a direct product of the energy conversion process and provides a way for the device to convert fluid mechanical energy into electrical energy.

[0033] The solar power generation unit 3 of this embodiment includes a solar panel 31. Four tilted solar panels 31 are evenly distributed around the outside of the friction nanogenerator 25. The solar panel 31 is connected to the support frame 4 by threads, and its tilt angle can be adjusted to achieve the highest energy utilization rate. The structure of the solar panel 31 from top to bottom is tempered glass, EVA, conductive copper strip, battery cell, EVA, TPT backboard, junction box, and finally a protective back shell. EVA is ethylene-vinyl acetate copolymer. The TPT backboard is made of polyester film (Polyester) covered with Tedlar polyvinyl fluoride film on both sides, which belongs to a known structure. In addition, by opening a drainage groove on the water accumulation plate under the water wheel 22, the outlet of the drainage groove is located above the solar panel 31, so that the water flow that impacts the water wheel 22 can be evenly drained to the solar panel 31, which can achieve the flushing and cleaning of dust and sand on the surface of the solar panel 31, and help the solar panel 31 to operate stably and permanently without maintenance for a long time.

[0034] The present invention collaboratively captures and utilizes rainwater energy, wind energy, and solar energy, realizing a multi-source collaborative energy collection strategy, greatly improving the system's power generation capacity and energy conversion efficiency, and significantly increasing the system's integration capability, operating stability, and reliability. The system has all-weather environmental energy recovery, conversion, and utilization capabilities, and is expected to provide long-term and stable energy supply for low-power electronic devices in wireless environmental sensor networks.

[0035] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
