Description

Technical Field

[0001] The present invention belongs to the technical field of air water collection, and in particular to an energy - free continuous water collection device that utilizes air flow disturbance combined with radiative cooling for heat dissipation. Background Technique

[0002] The wind turbine drives the blades to rotate through wind energy, enhancing the convection effect, and uses the pressure difference to introduce air into a specific device. Compared with traditional open - air containers, the air intake is increased under the same volume, but its efficiency will be greatly reduced when the wind speed is small or there is no wind, and electric energy is required to drive it again, increasing the energy consumption.

[0003] To dissipate the heat released by bead - like condensation, radiative cooling technology is often used. It is considered a green and low - carbon cooling method. Since the temperature of outer space is extremely low, only 3K, it is a natural huge cold storage for normal - temperature objects on the ground. Heat can be radiated into outer space without energy consumption by using the high - temperature difference between itself and outer space through direct sunlight. However, water droplets will adhere to the wall surface, affecting water collection and heat dissipation. The inefficient function of traditional radiative materials in air and the high water production cost severely limit their practical applications. Summary of the Invention

[0004] The purpose of the present invention is to solve the above - mentioned problems existing in the prior art, and provide an energy - free continuous water collection device that utilizes air flow disturbance combined with radiative cooling for heat dissipation.

[0005] To achieve the above - mentioned purpose, the present invention adopts the following technical solutions:

The rotational - speed sensing mechanism adjustment system is fixed on the vertical - axis wind turbine system. The vertical - axis wind turbine system is fixedly connected to the water collection container, and the radiative cooling heat dissipation device is fixed at the lower end of the water collection container.

[0007] The vertical - axis wind turbine system includes: an upper half - shaft, blades, a one - way bearing, a lower half - shaft, a small fan, a DC motor, a fixed housing, and a storage battery. Blades are fixed on the upper half - shaft. Four blades are provided, and the four blades are evenly distributed around the upper half - shaft as the center. The lower end of the upper half - shaft is connected to the lower half - shaft through a one - way bearing. A small fan is fixed on the lower half - shaft. The lower end of the lower half - shaft is fixedly connected to the output shaft of the DC motor. A fixed housing is fixed on the lower half - shaft, and the rotational - speed sensing mechanism adjustment system is arranged inside the fixed housing. The storage battery is connected to the DC motor through a wire.

[0008] The rotational - speed sensing mechanism adjustment system includes: a rotational - speed sensor and a single - chip microcomputer. The rotational - speed sensor is connected to the single - chip microcomputer through a wire. The single - chip microcomputer is connected to the DC motor and the storage battery through wires.

[0009] The water collection container includes: a barrel body, a porous aluminum cover, a spiral blade, and a protrusion. A porous aluminum cover is provided at the top of the barrel body. The lower half shaft rotates through the porous aluminum cover. A bracket is provided inside. Both the DC motor and the battery are fixed on the bracket. A spiral blade is fixed inside the barrel body, and a plurality of the protrusions are arranged along the spiral path on the spiral blade.

[0010] The shape of the radiative cooling heat dissipation device is a V-shaped structure, and a barrel body is fixed at the upper end of the radiative cooling heat dissipation device.

[0011] Radiative cooling materials are coated on both the inner and outer surfaces of the barrel body and the top surface of the radiative cooling heat dissipation device.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The present invention provides an energy-free continuous water collection device that utilizes air flow disturbance combined with radiative cooling heat dissipation, which can solve the problems raised in the background art. The present invention uses a wind turbine regulated by a rotational speed sensing mechanism to control the air flow rate and combines it with a lubricating coating on the device wall surface. When there is wind, the blades rotate to generate a pressure difference and can generate electrical energy at the same time. When there is no wind, the stored electrical energy continues to drive the blades to rotate. The present invention can achieve all-weather efficient air water collection under different environmental temperatures, humidity levels, and wind speeds, and perform convective heat dissipation and radiative cooling heat dissipation to maintain a low-temperature environment for the entire cooling device. This process utilizes solar energy and wind energy without additional energy input, which is energy-saving and environmentally friendly, and realizes a green and low-carbon air water collection mode, providing a promising strategy for the problems existing in remote, energy-poor, and water-shortage areas.

[0014] The present invention provides an energy-free continuous water collection device that utilizes air flow disturbance combined with radiative cooling heat dissipation, and develops a water collection system with low environmental requirements and strong adaptability. The present invention only uses solar energy and wind energy as energy sources and the atmosphere as the material source to produce water resources through natural circulation.

[0015] The present invention combines a vertical-axis wind turbine and a rotational speed sensing mechanism system, which has strong wind direction adaptability, a low starting wind speed, and a simple structure. Its lower end is closely connected to a coaxial small fan. This design aims to efficiently utilize the energy of natural wind. While pressing the atmospheric pressure into the cooling device for synchronous power generation, it can also increase the air flow disturbance inside the device to enhance the convective heat dissipation of the inner wall. Driven by the wind force, the blades rotate, thereby driving the DC motor to rotate. Finally, the generated electric energy is stored in the storage battery for energy storage. A single-chip microcomputer is introduced to the rotational speed sensing mechanism. When the speed sensor monitors that the wind speed and wind force are too small to generate a pressure difference, the single-chip microcomputer receives the feedback transmission signal. Therefore, this wind turbine can rotate stably in a predetermined direction, avoiding the dependence on environmental conditions of traditional wind turbines, enabling the continuous operation of the device without energy consumption, the small fan continuously rotates to create air flow disturbance, and to a certain extent, using the energy of natural wind to increase the convective heat dissipation.

[0016] The present invention uses polydimethylsiloxane (PDMS) elastomer as a radiative cooling coating for lubricating surfaces and cooling coatings. It has low cost, scalability, and good photothermal properties, endowing the material with hydrophobicity without affecting the radiative cooling performance. This radiative cooling material is applied and lubricated with silicone oil having a viscosity η = 10 cP (cP: centipoise). When using traditional materials, water droplets often adhere to the surface, resulting in a large amount of condensed water that cannot be collected. As a lubricating surface, it greatly reduces the adhesion of water droplets on the contact surface and effectively collects condensed water by gravity drive. Its water collection rate is twice that of a superhydrophobic surface in the same environment, and the coating achieves a water droplet collection rate as high as 90%.

[0017] The protrusions of the present invention adopt a conical structure imitating cactus spines, which can efficiently capture and transport water droplets. Through the helically arranged cactus-like structure, the contact time between air and the surface of the water collector is maximized, and at the same time, the natural forces of gravity, capillary action, and temperature gradient are utilized to promote the formation and removal of liquid droplets. Each cactus-like structure is arranged along a helical path, and an appropriate spacing is maintained between adjacent ones to ensure smooth air circulation. This layout not only increases the residence time of air inside the device but also provides a larger surface area for condensation. Description of the Drawings

Specific embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] An energy-free continuous water collection device using air flow disturbance combined with radiative cooling heat dissipation, comprising: a vertical axis wind turbine system 1, a rotational speed sensing mechanism adjustment system 1-8, a water collection container 2 and a radiative cooling heat dissipation device 3. The rotational speed sensing mechanism adjustment system 1-8 is fixed on the vertical axis wind turbine system 1. The vertical axis wind turbine system 1 is fixedly connected to the water collection container 2, and the radiative cooling heat dissipation device 3 is fixed at the lower end of the water collection container 2.

[0026] The vertical axis wind turbine system 1 includes: an upper half shaft 1-1, blades 1-2, a one-way bearing 1-3, a lower half shaft 1-4, a small fan 1-5, a DC motor 1-6, a fixed housing 1-7 and a battery 1-9. The blades 1-2 are fixed on the upper half shaft 1-1. Four blades 1-2 are evenly distributed around the upper half shaft 1-1 as the center. The lower end of the upper half shaft 1-1 is connected to the lower half shaft 1-4 through a one-way bearing 1-3. The small fan 1-5 is fixed on the lower half shaft 1-4. The lower end of the lower half shaft 1-4 is fixedly connected to the output shaft of the DC motor 1-6. The fixed housing 1-7 is fixed on the lower half shaft 1-4. The rotational speed sensing mechanism adjustment system 1-8 is arranged inside the fixed housing 1-7. The battery 1-9 is connected to the DC motor 1-6 through a wire.

[0027] The rotational speed sensing mechanism adjustment system 1-8 includes: a rotational speed sensor and a single-chip microcomputer. The rotational speed sensor is connected to the single-chip microcomputer through a wire. The single-chip microcomputer is connected to the DC motor 1-6 and the battery 1-9 through wires.

[0028] The water collection container 2 includes: a barrel body 2-1, a porous aluminum cover 2-2, a spiral blade 2-3 and a protrusion 2-4. A porous aluminum cover 2-2 is arranged at the top of the barrel body 2-1. The lower half shaft 1-4 rotatably penetrates through the porous aluminum cover 2-2. A bracket is arranged inside. The DC motor 1-6 and the storage battery 1-9 are both fixed on the bracket. The spiral blade 2-3 is fixed inside the barrel body 2-1. A plurality of the protrusions 2-4 are arranged on the spiral blade 2-3 along its spiral path.

[0029] The radiation cooling and heat dissipation device 3 is in a V-shaped structure. The barrel body 2-1 is fixed at the upper end of the radiation cooling and heat dissipation device 3.

[0030] The inner and outer surfaces of the barrel body 2-1 and the top surface of the radiation cooling and heat dissipation device 3 are all coated with a radiation cooling material.

[0031] The radiation cooling material is made of PDMS. That is, polydimethylsiloxane elastomer is used as the PDMS coating for lubricating the surface and the cooling coating. It has low cost, scalability and good photothermal performance, endows the material with hydrophobicity and does not affect the radiation cooling performance. Carbon black, which has strong absorption of visible light and near-infrared light in solar energy, is selected as the photothermal conversion material. The mixture of carbon black and the PDMS coating is coated on the inner and outer surfaces of the device by a simple coating method, and silicone oil with a viscosity η = 10 cP is used for lubrication. When using traditional materials, water droplets often adhere to the surface of the condensation device, resulting in a large amount of condensed water that cannot be collected. The PDMS coating lubricated with silicone oil as the lubricating surface greatly reduces the adhesion of water droplets on the contact surface and effectively collects the condensed water by gravity drive. Its water collection rate is twice that of the superhydrophobic surface in the same environment, and the PDMS coating reaches a water droplet collection rate as high as 90%.

[0032] Refer to Figures 1 to 5As shown in the figure, the present invention is an energy-free continuous water collection device that utilizes air flow disturbance combined with radiative cooling for heat dissipation. The vertical axis wind turbine system 1 rotates under the action of wind energy and drives the small fan 1-5 to rotate. When the small fan 1-5 rotates, it generates electrical energy in the DC motor 1-6 while pressing the humid air into the water collection container 2. The air disturbance generated by the rotation of the small fan 1-5 can also increase the convective heat dissipation inside the device, and the humid air condenses and slides into the barrel body 2-1. The vertical axis wind turbine system 1, the rotational speed sensing mechanism adjustment system 1-8, and the water collection container 2 are coaxially connected. The integrated device has overall innovation and makes up for the deficiencies when working alone by utilizing their respective advantages. The rotational speed sensing mechanism adjustment system 1-8 can receive the signal from the single-chip microcomputer regarding whether the rotational speed of the small fan can provide a required pressure difference, and acts as a motor to make the vertical axis wind turbine system 28 rotate when the pressure difference becomes small. The radiative cooling heat dissipation device 3, as the main heat dissipation source of the entire structure, creates a low-temperature environment for the device, condenses the humid air into water, and radiates the heat to outer space using radiative cooling materials to achieve high-efficiency condensation efficiency of radiative cooling.

[0033] As Figure 1 , Figure 2 shown, according to Bernoulli's principle, the vertical axis wind turbine system 1 presses the humid air into the water collection container 2 for condensation where the pressure is low at the place with high flow velocity. During the process of the blade 1-2 contacting the wind, taking one blade 1-2 as an example, it will generate a resistance along the relative wind speed direction and a lift force perpendicular to the wind speed direction. Under the action of the lift force, the four blades 1-2 rotate and are transmitted to the lower half shaft 1-4 through the upper half shaft 1-1 and the one-way bearing 1-3. The structure of the four blades 1-2 adopts the vertical axis micro-wind power generation structure, which can accept the wind from any direction compared with the traditional horizontal axis structure and can start at a lower wind speed. The small fan 1-5 rotates driven by the torque of the lower half shaft 1-4. Since the flow velocity is high and the pressure is low below it due to the rotation of the fan, the external humid air will enter the water collection container 2 from the porous aluminum cover 2-2 under the action of the atmospheric pressure for subsequent condensation collection, and the convective heat dissipation in the water collection container 2 will increase due to the rotation of the fan, accelerating the cooling.

[0034] The rotational speed sensing mechanism adjustment system 1-8 continuously monitors the rotational speed of the small fan 1-5. When the rotational speed rises due to the assistance of the DC motor 1-6, the feedback signal causes the single-chip microcomputer to adjust the power supply of the battery 1-9 to the DC motor 1-6 for operation. The blade 1-2, the upper half shaft 1-1, the lower half shaft 1-4, the small fan 1-5, and the DC motor 1-6 rotate coaxially. The DC motor 1-6 receives the mechanical energy generated by the rotation of the blade 1-2, and the coil inside it cuts the magnetic induction lines in the magnetic field to generate electric energy, which is stored in the battery 1-9. The DC motor 1-6 can operate in the DC motor state and the motor state, and can be switched according to the feedback signal of the rotational speed sensor and the single-chip microcomputer. The rotational speed sensor is used to monitor the rotational speed of the small fan 1-5 when the DC motor operates as a generator. When the rotational speed is lower than 1-2 m / s, the rotational speed sensor generates a feedback signal. The single-chip microcomputer is used to receive the feedback signal of the rotational speed sensor, amplify it, and transmit it to the battery 1-9 to make the DC motor 1-6 operate as a motor. When the DC motor 1-6 operates as a motor, the one-way bearing 1-3 is in the release mode. At this time, the upper half shaft 1-1 connected to the outer ring is in a free state. At the same time, the DC motor 1-6 drives the lower half shaft 1-4 and the small fan 1-5 to rotate. When the wind speed is sufficient, due to the relativity of the direction, the one-way bearing 1-3 is in the locked state, transmitting torque to make the blade 1-2 drive the upper half shaft 1-1 to rotate, and then transmitting torque through the one-way bearing 1-3 to drive the lower half shaft 1-4 and the small fan 1-5 to rotate together. At this time, the DC motor 1-6 is not powered and becomes a power generation state.

[0035] The barrel body 2-1 is a thin aluminum cylindrical container with an open upper end and is placed in the air. It adopts a cylindrical structure, and humid air can condense omnidirectionally on the inner surface, reducing the floor area while increasing the surface area. The protrusion 2-4 at the upper end of the spiral blade 2-3 adopts the conical structure of cactus spines, which can efficiently capture and transport water droplets. The protrusions 2-4 are arranged in a spiral along the spiral blade 2-3, which can maximize the contact time between the air and the surface of the water collector. At the same time, the formation and removal of droplets are promoted by the natural forces of gravity, capillary action and temperature gradient. With the help of lubricating surface materials, water can be collected faster. The radiation cooling heat dissipation device 3 has a radiation cooling material smeared on its top surface and wraps the water collection container 2 inside. First, a porous radiation cooling material is prepared by the simple and low-cost template method; small molecular weight silicone oil is used as a lubricant, and carbon black, which has strong absorption of visible light and near-infrared light in solar energy, is selected as a photothermal conversion material, and then solar energy is used to convert light energy into heat energy. Then, a mixture of carbon black and radiation cooling material is coated on the surface of the porous radiation cooling material containing silicone oil by a simple coating method. After curing, a hydrophobic radiation cooling material coating with photothermal properties is obtained, which has high light transmittance, anti-aging property, imparts hydrophobicity to the material, and does not affect the radiation cooling performance. It has high-efficiency radiation performance at night, and the refrigeration effect can reach 10°C. The angles between the two side walls of the radiation cooling heat dissipation device 3 and the water collection container 2 are both 45°, forming a V shape with a high reflectivity close to 1 in the mid-infrared region (4-20μm), which can achieve all-round and high-efficiency heat dissipation of the condensation device and direct the heat radiation into the sky.

[0036] Under the action of the overpressure difference generated by the rotation of the small fan 1-5, humid air is pressed into the barrel body 2-1 from the porous aluminum lid 2-2. The rotation of the small fan 1-5 enhances the air convection inside the barrel body 2-1 and enhances the heat exchange with the outside. The humid air in the aluminum barrel body 2-1 will condense into water droplets on the surface of the radiation cooling material coating lubricated with silicone oil. Compared with the traditional surface, the water droplets will be fixed on the surface, and active condensation water collection is required, wasting manpower and material resources. The radiation cooling material coating lubricated with silicone oil not only effectively doubles the local cooling power, but also realizes passive water collection, that is, the water droplets will slide closely along the lubricated surface under the action of gravity, and the passive water collection rate is twice that of the superhydrophobic surface under the same conditions. When the humid air condenses into water droplets, heat will be released. Due to the good thermal conductivity of aluminum, the temperature of the inner and outer wall surfaces of the cylindrical barrel body 2-1 made of thin aluminum sheets is approximately the same. The convective enhanced heat dissipation inside the barrel body 2-1 and the radiation cooling heat dissipation device 3 arranged outside the barrel body 2-1 as the main cooling method will also dissipate heat from the entire wall surface, and direct the heat radiation into the sky to maintain the temperature inside the device below the dew point of water and maintain the condensation rate of humid air.

[0037] The usage method of the present invention:

[0038] Before actual use, the device can be placed in an open area. When the wind blows towards the blades 1-2, a tangential force is generated on the blades 1-2 by the wind. Driven by the wind force, the blades 1-2 and the upper half shaft 1-1 rotate. The rotation of the upper half shaft 1-1 drives the lower half shaft 1-4 to rotate through the one-way bearing 1-3. As the rotational speed of the blades 1-2 increases, the force between the wind and the blades 1-2 reaches a dynamic balance. The rotation of the lower half shaft 1-4 drives the small fan 1-5 to rotate. According to Bernoulli's principle, the rotation of the small fan 1-5 generates a pressure difference inside the barrel 2-1, creating a low-pressure area inside the barrel 2-1, while the external humid air is in a relatively high-pressure state. Under the action of the pressure difference, the humid air is continuously inhaled into the barrel 2-1 through the porous aluminum cover 2-2.

[0039] When there is no wind or the wind speed is very low, the rotational speed of the blades 1-2 decreases, resulting in a decrease in the rotational speed of the small fan 1-5. When it is lower than 1-2 m / s, the rotational speed sensor monitors and sends a signal. After being driven by the single-chip microcomputer, the battery 1-9 releases electricity, causing the DC motor 1-6 to operate as a motor, driving the small fan 1-5 to rotate. Through the action of the one-way bearing 1-3, the DC motor 1-6 only rotates the lower half shaft 1-4 and does not drive the upper half shaft 1-1 to rotate, saving unnecessary power consumption.

[0040] When the wind speed increases or is very high, when the rotational speed sensor monitors an increase in the rotational speed and sends a signal, after being driven by the single-chip microcomputer, the battery 1-9 stops supplying power, causing the DC motor 1-6 to operate as a generator. It continues to use wind energy to drive the blades 1-2 and the small fan 1-5 to rotate. The rotational speed sensing mechanism adjustment system 1-8 realizes all-weather operation without energy consumption, maintaining a high intake volume of humid air and heat dissipation efficiency inside the condensation device.

[0041] After the humid air enters the barrel body 2-1, it will first come into contact with the low-temperature surface inside the barrel body 2-1. The low-temperature surface can maintain a relatively low temperature through convective heat transfer and radiative cooling. When the humid air comes into contact with the low-temperature surface, the water vapor in the air will reach the saturation state due to the temperature decrease and then start to condense into small water droplets. During the day, the radiative cooling material coating has a slightly poor cooling ability as a radiative material. Inside the device, the temperature is mainly reduced by increasing the air flow rate through the rotation of the small fan 1-5 to strengthen the convective heat transfer between the wall surface and the outside. At night, the polydimethylsiloxane coating of the radiative cooling material has good infrared emission performance without the interference of solar radiation. In the environment where the radiative cooling heat dissipation device 3 is located, the radiative cooling material can emit infrared radiation with a wavelength range of 8-13 μm. The infrared radiation in this wavelength range can effectively penetrate the atmospheric window, dissipate heat to the outer space, and the heat emitted outward will be greater than the heat absorbed, thus achieving a net cooling effect and providing a continuous low-temperature environment for the barrel body 2-1. Since the radiative cooling material coating covers the surface of the barrel body 2-1 and the thin aluminum sheet has good thermal conductivity, its cooling effect will be conducted to the inside of the barrel body 2-1 to help maintain the low-temperature environment inside the barrel body 2-1. This helps the humid air to condense faster after entering the condensation device and improves the condensation efficiency.

[0042] As the water vapor continuously condenses, the small water droplets will gradually accumulate on the inner and outer surfaces of the barrel body 2-1 and on the surface of the radiative cooling material coating. At the same time, the water droplets will form accumulations on the surface of the protrusion 2-4. Due to the good hydrophobicity of the radiative cooling material, the small water droplets will flow downward along the inner wall of the barrel body 2-1 and the spiral blade 2-3 under the action of gravity and converge to the bottom surface of the barrel body 2-1 to achieve the collection of liquid water resources. The entire working process is continuous and uninterrupted, and all parts of the system can work synchronously. The entire system operates with zero pollution and zero energy consumption, achieving sustainable development.
