[0002] With my country's rapid economic development, rising industrial production levels, and improving living standards, the nation's total electricity consumption has increased annually. In 2022, total electricity consumption reached 863.72 billion kWh, with 67.8% of this electricity coming from thermal power. This places high loads on thermal power plant cooling towers. Currently, there are no devices to utilize or recycle the kinetic energy of rising gases, lost water vapor, and the intense sunlight at the top of the towers.

[0003] Considering the large amount of material and energy stored in thermal power plant cooling towers and other industrial and chemical cooling towers, which are not utilized and wasted, it is necessary to design an efficient and comprehensive industrial cooling tower energy-saving system.

The sliding body can be driven by the pushing rod to perform linear motion along the length direction of the support member. One end of the first connecting rod is hinged to the sliding body, and the other end is hinged to the top plate of the frame together with the free end of the long rod body segment.

The inner cavity of the box body is divided into a parallel gel adsorption chamber and a water collection chamber. The water-absorbing gel medium is placed in the gel adsorption chamber to adsorb the rising steam in the industrial cooling tower. The top of the box body is a baffle made of a transparent material. The baffle is an inclined structure that gradually tilts from the water-absorbing gel chamber toward the water collection chamber. The light shield has a light-shielding position and an open position relative to the box body. When the light shield is in the light-shielding position, it can block the radiation of light to the box body.

The pressure sensor is arranged corresponding to the water-absorbing gel medium and is used to monitor the pressure exerted on it by the water-absorbing gel medium in real time. The pressure sensor transmits a signal to the linear voltage conversion module. The first processor receives the voltage value of the linear voltage conversion module and converts it into weight in real time. When the weight of the water-absorbing gel medium is detected to exceed a predetermined threshold, the processor can control the sunshade to move to its open position or sunshade position.

[0011] According to the industrial cooling tower energy recovery composite system of the present invention, the photovoltaic power generation device includes a concentrating cell and a translation plate, the concentrating cell is arranged on the upper side of the support plate, the translation plate is located above the concentrating cell and can be driven to perform reciprocating linear motion along the length direction of the support plate; a double convex lens is embedded in the translation plate so that the focusing point can converge on the concentrating cell.

The rotating blade group includes fixed blades and moving blades, the so-called fixed blades refer to the fixed blades whose positions and states relative to the base plate remain unchanged, and the so-called moving blades refer to the fixed blades whose positions and states relative to the base plate change. The fixed blades are arranged vertically on the base plate, and the moving blades have a flat position and a vertical position. The moving blades can be driven relative to the base plate and the fixed blades to switch between the flat position and the vertical position. In the flat position, the moving blades remain substantially parallel to or aligned with the base plate, and in the vertical position, the moving blades remain relatively perpendicular to the base plate. At this time, the rotating blade group can be used for rotational power generation.

[0014] In the present invention, the swing blades of the swing blade assembly are arranged vertically. In this context, the term "vertical" refers to a direction parallel to the length of the base plate. The swing blades of the swing blade assembly have an open position and a closed position. The swing blades can be manipulated relative to the base plate to switch between the open and closed positions. In the open position, the swing blades remain parallel to the base plate. In the closed position, the swing blades remain perpendicular to the base plate. In this configuration, the swing blade assembly can be used for swing power generation.

[0015] The variable blade mechanism of the present invention further includes a variable transmission mechanism capable of switching the movable blade between its horizontal position and a vertical position. The variable transmission mechanism can be driven by the movement of the swing blade between the closed position and the open position. By the movement of the swing blade from the closed position to the open position, the movable blade can be driven by the variable transmission mechanism to move from the horizontal position to the vertical position. By the movement of the swing blade from the open position to the closed position, the movable blade can be driven by the variable transmission mechanism to move from the vertical position to the horizontal position.

[0016] In the above implementation process, when the swing blade is in the closed position, the movable blades of the rotating blade group are in the horizontal position. At this time, the variable blade mechanism as a whole is in a mode capable of swinging and generating electricity. When the swing blade is in the open position, the movable blades of the rotating blade group are in the vertical position. At this time, the variable blade mechanism as a whole is in a mode capable of rotating and generating electricity. The operation of the variable transmission mechanism is carried out along with the movement of the swing blade between the closed position and the open position. Specifically, when the swing blade is operated to move from its closed position to the open position, the variable blade mechanism can be driven by the movement of the swing blade to move, thereby causing the movable blade to move from its horizontal position to the vertical position; when the swing blade is operated to move from its open position to the closed position, the variable blade mechanism is also driven to move in the opposite direction, thereby causing the movable blade to move from its vertical position to the horizontal position.

[0017] According to the industrial cooling tower energy recovery composite system of the present invention, the variable transmission mechanism includes a crank, a blade rack and a sliding component, the crank has a rotation center line parallel to the base plate, and the crank can be driven to rotate around its rotation center line in the plane in which it is located; the blade rack includes a transverse connecting rod, the free end of the crank is hinged to the transverse connecting rod of the blade rack, the sliding component of the variable transmission mechanism is movably connected to the free end of the transverse connecting rod, the fixed blade is provided with a slide groove along its own length direction, the sliding component is arranged in the slide groove and can move back and forth along the slide groove when the crank is driven, the crank, the transverse connecting rod of the blade rack and the sliding component of the variable transmission mechanism together form a crank slider mechanism; the blade rack also includes a vertical rod section, which is vertically connected to the transverse connecting rod and remains parallel to the rotation center line of the crank, and the moving blade is fixed on the vertical rod section in a relatively vertical manner.

[0018] In the above implementation, the vertical rod section of the blade rack has a first position relatively close to the base plate and a second position relatively far from the base plate. The blade rack is movable between the first and second positions under the action of a crank slider mechanism consisting of a crank, a transverse connecting rod of the blade rack, and a sliding member. When the vertical rod section of the blade rack is in the first position, the movable blades are in a horizontal position relative to the base plate. When the vertical rod section is in the second position, the movable blades are in a vertical position relative to the base plate.

[0019] According to the industrial cooling tower energy recovery composite system of the present invention, it also includes a swing blade drive mechanism, which includes a power source and a swing shaft. The swing shaft has an axis and the axis remains parallel to the base plate. The swing shaft can be driven to rotate around its own axis under the power provided by the power source, and the swing blades of the swing blade group are fixedly arranged on the corresponding swing shaft.

[0020] According to the industrial cooling tower energy recovery composite system of the present invention, the crank is fixedly arranged on the swing shaft in a relatively vertical manner, and the rotation center line of the crank coincides with the axis of the swing shaft.

[0021] In the present invention, the power source can be a servo motor, and the drive between the power source and the swing shaft can be achieved through a gear transmission. When the swing shaft is driven to rotate about its own axis, the swing blades fixed thereto perform synchronous rotational motion about the axis of the swing shaft, thereby achieving opening and closing. At the same time, the crank of the crank slider mechanism rotates about its own rotation centerline driven by the swing shaft, thereby driving the entire crank slider mechanism to operate. In other words, the movement of the swing blades between the closed and open positions is synchronized with the movement of the moving blades between the horizontal position and the vertical position, thereby achieving switching between the swing power generation mode and the rotation power generation mode.

[0022] According to the industrial cooling tower energy recovery composite system of the present invention, the crank slider mechanism is an offset crank slider mechanism, and there is an offset distance between the rotation center point of the crank and the movement center line of the sliding component.

[0023] According to the industrial cooling tower energy recovery composite system of the present invention, there are two stator blades arranged opposite to each other, the swing shaft is arranged between the two stator blades, and the two ends of the swing shaft are respectively arranged in the swing shaft holes of the corresponding stator blades.

[0024] According to the variable-property blade mechanism for wind power generation disclosed in the first aspect of the present invention, two opposing moving blades are arranged. The mounting positions of the two moving blades and the two fixed blades together form a cross-shaped structure. A variable-property transmission mechanism is provided for each moving blade. In the present invention, in the rotary power generation mode, the power source drives the swing shaft to rotate, and an offset crank-slider mechanism is used to cause the two swing blades to open, simultaneously driving the two vertical rod segments carrying the moving blades to stretch and stand upright. At this point, the two moving blades and the two rotating blades mounted opposite each other on the base plate together form a four-blade rotating configuration.

[0025] According to the industrial cooling tower energy recovery composite system of the present invention, the variable configuration power generation mechanism also includes a swinging power generation device and a rotating power generation device; when the swinging blades of the swinging blade group are in a closed position, the moving blades of the rotating blade group are in a flat position, and at this time the swinging blade group of the variable configuration blade mechanism can swing under the action of the kinetic energy of the wind body, so that the variable configuration blade mechanism can perform work on the swinging power generation device; when the swinging blades of the swinging blade group are operated to move from the closed position to the open position, the moving blades of the rotating blade group can be driven to move to a vertical position, and at this time the rotating blade group of the variable configuration blade mechanism can drive the variable configuration blade mechanism as a whole to rotate under the action of the kinetic energy of the wind body, so as to perform work on the rotating power generation device.

[0026] According to the industrial cooling tower energy recovery composite system of the present invention, the variable configuration power generation mechanism further includes a swing power generation transmission mechanism, a rotation power generation transmission mechanism and a transmission switching mechanism, the swing power generation transmission mechanism includes a bridge rod, a gear, a rack and an elastic element, one end of the elastic element is connected to the swing power generation device, and the other end is fixedly connected to the end of the rack, the rack is meshed with the gear, the bridge rod is fixedly arranged on the end face of the gear, and the base plate of the variable configuration blade mechanism can be operated to form a transmission connection with the bridge rod during swing power generation, and can be operated to separate from the bridge rod during rotation power generation; The rotating power generation transmission mechanism includes a rotating power generation transmission shaft, which is arranged perpendicular to the substrate, one end of the rotating power generation transmission shaft passes through the center of the gear and is fixedly connected to the substrate, and the other end forms a transmission connection with the rotating power generation device; the transmission switching mechanism includes a sliding support and a slide rail, and the rotating power generation device is fixedly arranged on the sliding support, and the sliding support can be operated to drive the rotating power generation device, the rotating power generation transmission shaft and the substrate to perform linear motion in the axial direction of the rotating power generation transmission shaft, so that the substrate can be combined with or separated from the bridging rod of the swinging power generation transmission mechanism.

[0027] According to the industrial cooling tower energy recovery composite system of the present invention, the wind power generation device also includes a vortex generator for generating the shedding vortex required for swing power generation. The vortex generator is arranged below the variable blade mechanism. The vortex generator is a variable diameter structure whose radial cross-sectional diameter can be changed, so as to be able to adjust the swing amplitude of the swing blade during swing power generation.

[0041] Figure 1 The overall structural diagram of the industrial cooling tower energy recovery composite system of the present invention is shown. Figure 2 The overall structural diagram of the wind power generation device of the present invention is shown, wherein the swing blades in the variable blade mechanism are in a closed position, and the moving blades of the rotating blade group are in a flat position. At this time, the wind power generation device is in a state where it can swing to generate electricity. Figure 3 A schematic diagram of the overall structure of the wind power generation device of the present invention is shown, wherein the swing blades of the variable blade mechanism are in the open position, the moving blades of the rotating blade group are in the vertical position, and the base plate is separated from the bridging rod of the swing power generation transmission mechanism. At this time, the wind power generation device is in a state where it can rotate to generate electricity. Figure 4 A simplified diagram of the variable transmission mechanism of the present invention is shown.

[0042] Combine Figure 1 The present invention discloses a composite energy recovery system for an industrial cooling tower, comprising a support plate, a wind power generator, a solar power generator, and a water collection device. During use, the entire composite energy recovery system is fixedly installed within the tower opening of the industrial cooling tower using the support plate. After installation, the wind power generator and the water collection device are located below the solar power generator and within the tower, with the water collection device located laterally outside the solar power generator.

[0043] Combine Figure 1As shown, the present invention provides a water collection device comprising a housing 49, a water-absorbing gel medium, and a light shield 50. The interior of the housing 49 is divided into a parallel gel adsorption chamber 54 and a water collection chamber 55. The water-absorbing gel medium is placed in the gel adsorption chamber 54 to absorb rising steam within the industrial cooling tower. The top of the housing 49 is a baffle 53 made of a transparent material. The baffle 53 is inclined gradually from the water-absorbing gel chamber toward the water collection chamber 55. The light shield 50 has a light-shielding position and an open position relative to the housing 49. When the light shield 50 is in the light-shielding position, it blocks light from radiating toward the housing 49. When the light shield 50 is in the open position, light can radiate toward the housing 49, thereby irradiating the water-absorbing gel medium. When the housing 49 is positioned within the tower, its upper portion faces direct sunlight, while its lower portion faces direct water vapor flow.

[0044] In the water collection device of the present invention, the water-absorbing gel medium utilizes a polyacrylamide-based composite hydrogel with high saturation absorption and efficient desorption, significantly improving water collection efficiency. The highly saturated, fast-desorbing gel, combined with the sunshade 50, significantly increases water collection capacity while eliminating white plume at the top of the tower and improving both light energy reception and conversion rates.

[0045] The water collection device of the present invention is also equipped with a water collection control system, comprising a pressure sensor, a linear voltage conversion module, and a first processor. The pressure sensor is positioned relative to the absorbent gel medium and is used to monitor the pressure exerted on it by the absorbent gel medium in real time. The pressure sensor transmits a signal to the linear voltage conversion module. The first processor receives the voltage value from the linear voltage conversion module and converts it into weight in real time. When the weight of the absorbent gel medium exceeds a predetermined threshold, the processor controls the movement of the light shielding plate 50 to its open or light-shielding position. The specific information transmission process is as follows: the pressure sensor at the bottom of the housing 49 detects the weight in real time. When the absorbent gel medium is saturated, the pressure sensor transmits a signal to the linear voltage conversion module. The voltage conversion module then outputs a voltage value within a certain range to the first processor (microprocessor), which performs ADC acquisition and converts the acquired voltage value into weight in real time. The opening and closing of the light shielding plate 50 is then controlled by setting a fixed threshold.

[0046] The working process of the water collection device is as follows: a channel plate is provided at the bottom of the box 49 of the water collection device, and the polyacrylamide-based composite hygroscopic hydrogel is placed on the channel plate of the box 49, and the water vapor in the industrial cooling tower can enter the water-absorbing gel cavity through the channel plate; in the adsorption stage, the shading plate 50 is closed and is in its shading position, and the lower water vapor is adsorbed by the polyacrylamide-based composite hygroscopic hydrogel through the channels on the channel plate; when the water collection control system detects that the polyacrylamide-based composite hygroscopic hydrogel has reached saturation, it enters the desorption stage, and controls the shading plate 50 to open and enter its open position, at which time light can radiate into the box 49; under the radiation of light, the polyacrylamide-based composite hygroscopic hydrogel releases water vapor, and the water vapor will condense into small water droplets when it encounters the condensation inclined baffle, slide down the condensation inclined baffle, and drip into the water collection cavity 55.

[0047] In the present invention, the polyacrylamide-based composite hygroscopic hydrogel can be prepared in the following manner: during the preparation process, ultrasound is used to make the dispersion more uniform so that the subsequent reaction can occur better, and then nitrogen is introduced into the PPy and AM mixture.

[0048] The performance test of polyacrylamide-based composite hygroscopic hydrogel is shown below.

[0049] Water absorption experiment: 0.3728g dry gel absorbs 0.6888g of water in a steam environment. The data is recorded and the water absorption curve is drawn (such as Figure 7 As shown), it is calculated that the water absorption rate in 6 hours can reach up to 184.76%, and the water absorption capacity of 1 kg of gel is about 1.8 kg, that is, 1.8 L of water.

[0050] Desorption experiment: 1.0616g wet gel desorbed 0.5794g water under light environment. The data were recorded and the desorption curve was drawn (such as Figure 8 As shown), it is calculated that 1 kg of wet gel can release about 1.56 kg of water, that is, 1.56 L of water.

[0051] Combine Figure 1 As shown, the present invention also provides a solar power generation device, which is connected to the upper side of the support plate and is used to convert received light energy into electrical energy. In the present invention, the solar power generation device is based on high-efficiency planar micro-tracking lenticular lens focusing technology, and is designed to be a planar micro-tracking lenticular lens array concentrating power generation device under the global light environment at the tower mouth.

[0052] In a preferred embodiment, the photovoltaic power generation device includes a concentrating cell and a translation plate. The concentrating cell is disposed on the upper side of the support plate. The translation plate is located above the concentrating cell and can be driven to perform reciprocating linear motion along the length of the support plate. A biconvex lens is embedded in the translation plate to enable the focal point to converge on the concentrating cell. The corresponding photovoltaic power generation device is also provided with a light tracking control system, including a photodiode, a light intensity conversion circuit, and a second processor. The photodiode is used to collect light source signals to determine the direction of strongest illumination. The light intensity conversion circuit converts the signal related to changes in light intensity collected by the photodiode into a voltage signal. The second processor receives the voltage signal input from the light intensity conversion circuit and controls the rotation of the translation plate drive motor based on the received voltage signal to ensure that the focal point of the biconvex lens mounted on the translation plate remains focused on the concentrating cell in real time. In the present invention, the photovoltaic power generation device is placed above the wind power generation device and can receive global illumination from the cooling tower outlet. The translation plate embedded with a double convex lens can be moved horizontally in the slide under the control of the light tracking control system, so that the focusing point converges on the high-efficiency concentrating cell.

[0053] In a preferred embodiment, based on the device size, the concentrator cell panel length l1 is set to 270 mm and the width l2 is set to 140 mm. Since the cooling tower is unobstructed, DNI / GNI can be set to > 50% (direct / global normal irradiance = DNI / GNI). According to the formula for the focal length of the biconvex mirror: (H-BaF5, spherical radius r1=r2=29.2mm, refractive index n=1.55) we can get f 双凸 =26.54, then when working, the distance d from the center of the double convex lens array panel to the upper surface of the Si-MJ solar panel is f 双凸 =26.54. Since direct light accounts for approximately 50%, the number of hexagonal biconvex mirror units is: It is approximately composed of 83 biconvex lens units. The parameters are as follows: R = 0.5, D = 12 (radius of the hexagonal circumscribed circle).

[0054] Combine Figure 1-Figure 3As shown, the industrial cooling tower energy recovery composite system of the present invention also includes a wind power generation device, which includes a variable configuration power generation mechanism, which includes a variable configuration blade mechanism, an oscillating power generation device, an oscillating power generation transmission mechanism, a rotating power generation device, and a rotating power generation transmission mechanism. A wind power generation installation assembly is provided relative to the wind power generation device. The wind power generation installation assembly has a frame 1, which includes a vertical main plate 2, a top plate 3, and a bottom plate 4. The top plate 3 and the bottom plate 4 remain parallel and are respectively fixed to the end portions of the vertical main plate 2 in a vertical manner. The frame 1 also includes a horizontal yaw mounting plate 5, which remains parallel to the top plate 3 and the bottom plate 4 and is vertically connected to the middle portion of the vertical main plate 2. The wind power generation installation assembly also includes a spatial yaw adjustment mechanism for adjusting the spatial direction of the variable configuration power generation mechanism. The yaw adjustment mechanism includes a horizontal yaw drive mechanism and a vertical yaw drive mechanism. The horizontal yaw drive mechanism can drive the variable configuration power generation mechanism as a whole to rotate in the horizontal direction to adjust the horizontal yaw drive angle of the variable configuration blade mechanism facing the wind, and the vertical yaw drive mechanism can drive the variable configuration power generation mechanism as a whole to tilt in the vertical direction to adjust the vertical angle of the variable configuration blade mechanism facing the wind.

[0055] Combine Figure 1 and Figure 3 As shown, the horizontal yaw drive mechanism includes a driving gear 6, a driven gear 7 and a main shaft 8. The driving gear 6 is driven to rotate by a power device (such as a servo). The axis of the main shaft 8 is parallel to the vertical main plate 2. The main shaft 8 is arranged between the top plate 3 and the horizontal yaw mounting plate 5 in a manner that allows it to rotate around its own axis. The driven gear 7 is fixed to the main shaft 8 and meshes with the driving gear 6. The variable-configuration power generation mechanism in the present invention is fixedly connected to the main shaft 8 as a whole, so that when the main shaft 8 is driven by the gear transmission pair to rotate around its own axis, the entire variable-configuration power generation mechanism will rotate in the horizontal direction accordingly, thereby adjusting the horizontal wind angle of the variable-configuration blade mechanism and adapting to changes in different wind fields.

[0056] Combine Figure 1As shown, the vertical yaw drive mechanism includes a first connecting rod 10, a second connecting rod, a sliding body 11 and a pushing rod 12. The second connecting rod is an inverted V-shaped structure, including a long rod body section 13 and a short rod body section 14. The long rod body section 13 and the short rod body section 14 are connected to form an inverted V-shaped structure.

The fulcrum where the long rod body section 13 and the short rod body section 14 are connected is hingedly set on a support member hinge seat 15 on the lower side of the support member 9. The free end of the long rod body section 13 is hingedly set on a second hinge seat 16 on the top plate 3 of the frame 1 with the first connecting rod 10. The free end of the short rod body section 14 is fixedly connected to the top plate 3 of the frame 1. The first connecting rod 10 is hinged to the sliding body 11 at one end away from the second connecting rod. The sliding body 11 can be driven by the pushing rod 12 to make a linear motion along the length direction of the support member 9 so that The hinge point between the first connecting rod 10 and the sliding body 11 can be closer to or farther away from the hinge point between the fulcrum of the second connecting rod and the supporting member 9, thereby making the inclination angle of the frame 1 as a whole on the vertical plane adjustable. Since the variable-configuration power generation mechanism is arranged on the frame 1, when the inclination angle of the frame 1 as a whole on the vertical plane is adjusted, the inclination angle of the variable-configuration power generation mechanism in the vertical direction is also adjusted accordingly. Therefore, the wind-facing angle of the variable-configuration power generation mechanism in the vertical direction can be adjusted to adapt to different wind fields.

[0057] In the present invention, the horizontal yaw drive mechanism and the vertical yaw drive mechanism can work independently, and can be adjusted separately or simultaneously without interfering with each other.

[0058] Combine Figure 1-Figure 3As shown, in the wind power generation device of the present invention, the variable blade mechanism includes a base plate 17, a rotating blade assembly, and an oscillating blade assembly. The rotating blade assembly is used for rotational power generation, while the oscillating blade assembly is used for oscillating power generation. The rotating blade assembly includes stator blades 18 and moving blades 19. In a preferred embodiment, two stator blades 18 are provided, and two moving blades 19 are also provided. The two stator blades 18 are arranged parallel to each other and perpendicularly on the base plate 17. The moving blades 19 are fixed to a blade frame independent of the base plate 17. The moving blades 19 have a horizontal position and a vertical position relative to the base plate 17 and can be driven to switch between the horizontal position and the vertical position relative to the base plate 17 and the stator blades 18. In the horizontal position, the moving blades 19 remain substantially parallel to or aligned with the base plate 17. In the vertical position, the moving blades 19 remain relatively perpendicular to the base plate 17. In this position, the rotating blade assembly can be used for rotational power generation. Furthermore, the moving blades 19 are close to the base plate 17 in the horizontal position and relatively far from the base plate 17 in the vertical position. When the moving blades 19 are in a vertical state, the two fixed blades 18 and the two moving blades 19 together form a four-rotor blade structure.

In the open position, the swing blades 25 remain parallel to the substrate 17, and in the closed position, the swing blades 25 remain vertical to the substrate 17. At this time, the swing blade group can be used for swing power generation.

[0060] In the present invention, the variable blade mechanism is capable of switching between a swinging power generation mode and a rotational power generation mode.

When the swinging blades 25 are in the open position, the moving blades 19 of the rotating blade assembly are in a vertical position, and the variable blade mechanism as a whole is in a rotational power generation mode. The variable blade mechanism operates in conjunction with the movement of the swinging blades 25 between the closed and open positions. Specifically, when the swinging blades 25 are operated to move from the closed position to the open position, the variable blade mechanism is driven by the movement of the swinging blades 25, thereby moving the moving blades 19 from their horizontal position to their vertical position. When the swinging blades 25 are operated to move from their open position to the closed position, the variable blade mechanism is similarly driven to move in the opposite direction, thereby moving the moving blades 19 from their vertical position to their horizontal position.

The moving blade is perpendicular to the extension line of the transverse connecting rod and is fixedly connected. According to functional requirements and to prevent the device from being too large, the mechanism does not adopt the rod length condition OA+e≤AB (e is the distance between O and L1, that is, the offset distance). According to the requirements, the crank OA=70mm and the offset distance e=11.5mm are set. According to the minimum transmission angle formula That is, there is no dead point, and the device can realize the corresponding conversion function.

[0063] Furthermore, the device further includes a swing blade drive mechanism, which includes a power source and a swing shaft 26. The swing shaft 26 has an axis parallel to the base plate 17.

[0066] In a preferred embodiment, the swing shaft 26 is disposed between the two stator blades 18 , and both ends of the swing shaft 26 are respectively fitted in the swing shaft holes 27 of the corresponding stator blades 18 . Furthermore, the two swing blades 25 are disposed between the two stator blades 18 .

[0067] In the present invention, it also includes a swinging generator 28 and a rotating generator 29. The swinging generator 28 is a swinging generator, and the rotating generator 29 is a rotating generator. When the swinging blades 25 of the swinging blade group are in a closed position, the moving blades 19 of the rotating blade group are placed flat. At this time, the swinging blade group of the variable blade mechanism can swing under the action of the kinetic energy of the wind body, so that the variable blade mechanism can do work on the swinging generator 28. When the swinging blades 25 of the swinging blade group are operated to move from the closed position to the open position, the moving blades 19 of the rotating blade group can be driven to move to a vertical position. At this time, the rotating blade group of the variable blade mechanism can drive the variable blade mechanism as a whole to rotate under the action of the kinetic energy of the wind body to do work on the rotating generator 29.

[0068] Combine Figure 1-Figure 3 As shown, the wind power generation device of the present invention also includes a swing power generation transmission mechanism and a rotation power generation transmission mechanism, wherein the swing power generation transmission mechanism includes a bridge rod 30, a gear 31, a rack 32 and an elastic element, one end of the elastic element is connected to the swing power generation device 28, and the other end is fixedly connected to the end of the rack 32, the rack 32 is engaged with the gear 31, the bridge rod 30 is fixedly arranged on the end face of the gear 31, and the substrate 17 of the variable blade mechanism can be operated to form a transmission connection with the bridge rod 30 during swing power generation, and can be operated to separate from the bridge rod 30 during rotation power generation; the rotation power generation transmission mechanism includes a rotation power generation transmission shaft 33, the rotation power generation transmission shaft 33 is arranged in a manner perpendicular to the substrate 17, one end of the rotation power generation transmission shaft 33 passes through the center of the gear 31 and is fixedly connected to the substrate 17, and the other end is transmission-connected to the speed increaser 40 through a coupling, and the speed increaser 40 is transmission-connected to the rotation power generation device 29 through a coupling.

[0069] Combine Figure 3As shown, the swing transmission mechanism can be operated to disengage from the base plate 17 via a transmission switching mechanism, so that the base plate 17 is free from constraints when performing rotational motion. The transmission switching mechanism includes a sliding support 38 and a slide rail 39. The rotating power generation device 29 is fixedly arranged on the sliding support. The sliding support 38 can be operated by a drive rod 41 to drive the rotating power generation device 29, the rotating power generation transmission shaft 33, and the base plate 17 to perform linear motion in the axial direction of the rotating power generation transmission shaft 33, so that the base plate 17 can be connected to or separated from the bridge rod 30 of the swing power generation transmission mechanism.

[0070] In the present invention, it also includes a mounting frame fixedly connected to the main shaft 8, the mounting frame includes a first mounting plate 34 and a second mounting plate 35, the two mounting plates are fixedly connected, the swing power generation transmission mechanism is installed on the first mounting plate 34, the rotating power generation device and the transmission switching mechanism are installed on the second mounting plate 35, and a guide rod 36 is provided at the bottom of the second mounting plate 35, the end of the guide rod 36 cooperates with the horizontal yaw mounting plate of the frame, and the horizontal yaw mounting plate is provided with a guide rail for accommodating the end of the guide rod 36 and guiding it during horizontal yaw. In the present invention, the guide rail is a guide groove 37.

[0071] In the present invention, the swing power generation by means of the swing of the swing blade 25 is realized by means of the Karman vortex street principle, specifically: Figure 1-Figure 3 As shown, the wind power generation device also includes a vortex generator for adjusting the swing amplitude of the swing blades 25 during swing power generation. The vortex generator is arranged below the variable blade mechanism and is a variable diameter structure with a variable radial cross-sectional diameter. The vortex generator is a non-streamlined generator, which is arranged below the variable blade mechanism. When the wind flow passes through the vortex generator, it periodically sheds vortices with opposite rotation directions and regular arrangement on both sides and behind it. The continuous pressure fluctuations caused by these vortices can cause the swing blades 25 in the closed position to vibrate at extreme amplitude, thereby causing the base plate 17 to produce reciprocating vibrations, which in turn drives the swing power transmission mechanism to perform work on the swing generator 28, causing the swing generator 28 to generate electricity.

[0072] Combine Figure 1-Figure 3As shown, in the present invention, the vortex shedder 42 comprises a central rod 43 and a plurality of side rods 44 arranged circumferentially along the central rod 43. The side rods 44 are parallel to the central rod 43 and connected to the central rod 43 via hinged support links 45. The present invention also includes a variable diameter drive mechanism comprising a drive sleeve 46, a drive link 47, and a slider-screw mechanism. The drive sleeve 46 extends over the outer surface of the central rod 43 and is capable of linear motion relative to the central rod 43. The drive sleeve 46 is fixedly connected to a slider 48 in the slider-screw mechanism. The distal end of the drive sleeve 46 is hingedly connected to the support link 45 of the vortex shedder 42 via the drive link 47, forming a structure similar to the frame of an umbrella. When the drive sleeve 46 linearly moves under the influence of the slider 48, the drive link 47 drives the support link 45 to expand or contract, causing the side rods 44 to move away from or toward the central rod 43, thereby achieving variable diameter of the vortex shedder 42.

[0073] In the present invention, the diameter change of the vortex generator 42 is achieved by the control module. After the wind speed detection module detects and predicts the wind speed, the STM32 chip ALU module calculates the diameter d1 of the generator required to make the swing plate reach the maximum amplitude in this wind field. The relationship between x1 and d1 can be calculated:

[0074]

[0075] The distance Δx=x1-x0 that the screw needs to be pushed out is obtained, and a closed-loop position PID control algorithm is used to accurately control the distance the screw moves to achieve the purpose of controlling the diameter of the generator.

[0076] The present invention solves the following technical problems:

[0077] 1. The use of variable blade mechanism solves the problem that swing power generation and vertical wind power generation cannot be used interchangeably.

[0078] Traditional wind turbines have a fixed structure and a single applicable scenario. Despite the support of the yaw system, they still fail to meet the needs of diversified scenarios. This can be attributed to the fact that swing power generation and vertical and horizontal axis wind turbines are not efficiently combined. The mechanical part of the wind power generation module of this device uses a similar offset crank slider mechanism. Through the ingenious design of mechanical transformation and feasibility verification, swing power generation and vertical axis rotation power generation are linked. Combined with the spatial yaw system, the device can switch between different modes under different wind field conditions to adapt to wind field changes and maximize wind energy utilization. For example, when the cooling tower is working at high load during the day to generate turbulence and low load or non-working at night to generate low-speed airflow, the swing power generation mode is used; and when normal load work during the day to generate medium-speed airflow, the rotation power generation mode is used.

[0079] 2. Use vortex shedding frequency control technology to solve the problem of low efficiency of existing swing power generation

[0080] The vibration frequency of existing oscillating power generation devices varies with the ambient wind speed and direction, making it difficult for the device to achieve resonance and maximum amplitude power generation, which greatly reduces the utilization rate of wind energy. The wind power generation module of this device combines the variable diameter mechanism, feedback control system, and spatial yaw system, and then combines the derived generator cross-sectional size control formula:

[0081]

[0082] The vortex shedding frequency f^ of the incoming gas in the tower at different wind speeds and wind downs is always close to the natural frequency fn of the swing power generation part, achieving an efficient working state in which the swing plate maintains resonant extreme amplitude power generation.

[0083] 3. Use micro-tracking technology to solve the problems of high cost and low sunlight utilization in traditional solar power generation.

[0084] Traditional concentrated photovoltaics (CPV) require dual-axis trackers and a large footprint, making them incompatible with tower-top installation requirements. This device, combined with planar micro-tracking technology, has been designed to create a photovoltaic module suitable for tower-top applications. This device can track the focal point at a micro-distance, focusing direct light onto high-efficiency MJ cells while absorbing diffuse light onto low-cost Si cells. This improves the overall efficiency of tower-top and large-planar photovoltaic power generation.

[0085] 4. Use polyacrylamide-based composite hygroscopic hydrogel to solve the problem of water mist hindering light energy absorption rate.

[0086] Water molecules and tiny water droplets in the mist at the cooling tower outlet scatter and absorb sunlight, reducing its penetration. This reduces the amount of light incident on the solar panels, resulting in a 20% to 30% drop in their output power. Excessive mist can lead to excessive humidity in the solar panels, further impacting their power generation efficiency. To ensure the proper power generation efficiency of the solar panels, in addition to considering the mist in the cooling tower before installation and selecting the appropriate location and angle to minimize obstruction by the mist, a polyacrylamide-based composite hygroscopic hydrogel water collection device was designed. This device is placed below the lenticular micro-tracking solar module. The hygroscopic hydrogel absorbs the mist, minimizing its "whitening" effect and improving the efficiency of the lenticular micro-tracking solar power generation system. It also collects and utilizes moisture.

[0087] Analysis of the energy-saving effect of the present invention:

[0088] 1. Calculation of power generation:

[0089] The present invention has a very high power generation and energy saving effect. According to the formula, the power generated per hour is:

[0090]

[0091] Where: E th is the annual theoretical power generation in MW·h; n is the number of wind turbine generator sets; v1 is the wind turbine cut-in wind speed (m / s); v2 is the wind turbine cut-out wind speed (m / s); P i is the power generation power (MW) when the wind speed is v; f i (v) is the probability distribution of wind speed at the turbine height of the i-th wind turbine.

[0092] Assuming the number of units n = 1, through fluid dynamics analysis, the cut-in wind speed v1 = 3.615m / s, the cut-out wind speed v2 = 0.996m / s, f i (v) is the Weibull distribution obtained by fitting the wind speed time series at an altitude of 200 meters. Substituting it into the calculation, the annual theoretical power generation Eth of one such power generation device can reach 31076.108 (MW·h).

[0093] 2. Calculation of recycled water:

[0094] Based on the amount of water released by the hydrogel in 6 hours, it can be estimated that the amount of water released in 12 hours by a hydrogel with M0 = 1 kg is about 2.5 L. If M = 10 kg of hydrogel is loaded in the device, the amount of water q' that can be collected by each device in one year is:

[0095] q′=q×M×365=9.12t;

[0096] The diameter of the cooling tower bottom is 65~120m, S=6358.5m 2 The device in this design occupies an area of 1m 2 , the diameter of the cooling tower top is 90m, and the area occupied by the equipment is 1 / 2 of the total area of the tower top. The number of devices N installed on the top of a cooling tower can be calculated as:

[0097]

[0098] Therefore, the annual water collection capacity Q of each cooling tower is: Q = q' × N = 29017.5t;

[0099] Chongqing currently has 11 medium-sized and larger thermal power plants and 18 chemical production enterprises. Assuming that each enterprise has one cooling tower, the annual water collection capacity Q' of the above 29 cooling towers is:

[0100] Q′=29×Q=841507.5t;

[0101] The average annual water consumption of a household is about 120 tons, and the annual water collection capacity of 29 cooling towers can supply the annual water for 7,012 households.

[0102] The present invention designs an innovative mechanical variable configuration power generation module and a spatial yaw control system. The former realizes the interactive cooperation of swing and rotation power generation, so that the device uses the swing power generation form under low wind speed or turbulent conditions, and uses the rotation power generation form under medium wind speed conditions, so that the power generation system stably converts and outputs electrical energy; the latter solves the problem of difficult breakthrough of three-dimensional space yaw, so that the alternating pressure on both sides of the device's swing blades is uniform or the wind direction is always perpendicular to the rotating power generation axis. The combination of the two makes the device suitable for various wind field conditions and greatly improves the wind energy conversion efficiency. In addition, the present invention designs and applies an innovative vortex shedding frequency feedback control system to ensure that the swing power generation module always maintains the resonant extreme amplitude power generation working state, maximizes the use of real-time wind energy, and maximizes the wind energy conversion efficiency.

[0103] The present invention uses micro-tracking technology to design a solar power generation system, so that the double convex mirror focusing plate can focus direct light on the high-efficiency concentrating cell with a millimeter movement, thereby maximizing the utilization rate of light energy.

[0104] The present invention adopts polyacrylamide-based composite hygroscopic hydrogel material and combines it with a mechanical structure to achieve "water collection" and "whitening" at the tower mouth to increase the light energy absorption rate and conversion rate of the system's photoelectric module.

[0105] The overall system of the present invention occupies an area of less than 2m 2 Thousands of these towers can be installed in a rigid, frame-like configuration at the tower mouth to maximize the development and utilization of clean energy and create a diversified energy supply. Furthermore, the recovery of water vapor within the tower can significantly reduce energy consumption for factories, especially those in water-scarce regions. In the future, this project is expected to not only cover hundreds of thousands of cooling towers in my country's thermal power plants and chemical plants, but can also be retrofitted and placed in diverse environments, such as farms and deserts, to recycle and reuse physical energy. This will promote China's clean energy development, water resource protection, and sand dune irrigation, creating energy-saving and emission-reduction demonstration zones and providing technical support and development direction for energy-saving and emission-reduction supervision.

[0106] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
