[0001] The present invention relates to the technical field of solar power generation, and more specifically to a camera that utilizes wind energy, rainwater and solar energy for combined power generation. Background Art

[0002] At present, most of the power supply of outdoor surveillance cameras adopts the traditional power grid. However, in the wild areas, the population is sparse and the power grid is often not laid. It is very troublesome to replace the battery. Although there are cameras powered by solar energy, it is easy to have insufficient solar energy in the rainy season or winter in the north, so the power grid is often needed to supplement. Therefore, the existing solar cameras are not practical. In nature, solar energy, wind energy, rain energy and other energies are inexhaustible. At present, in addition to solar energy, common energy collection methods also include wind power generation, rainwater power generation, etc. How to convert these energies into electrical energy can effectively power the camera.

[0007] Preferably, the inner rotating wheel is connected to the rotating shaft via a one-way bearing.

The outer wheel is connected to the inner wheel through a connecting rod. The inner wheel is unidirectionally connected to the shaft of the wind turbine generator. The shaft of the wind turbine generator is only pushed to rotate when there is water flow, increasing the power generation efficiency. Since the hydraulic drive wheel and the shaft are unidirectionally connected, the fan blades drive the shaft to rotate when there is no water, which will not cause the hydraulic drive wheel to rotate. When there is water, the rotation of the hydraulic drive wheel will drive the shaft to rotate, thereby driving the wind turbine to generate electricity. After the water flows from the outlet pipe into the central inner cavity of the column, the hydraulic generator therein generates electricity through the drop of rainwater.

[0016] In windy or rainy environments, wind and rain come into contact with the front surface of the nano friction generator, generating friction, which is converted into electrical energy to provide additional power support for the system.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0020] The camera using wind energy, rainwater and solar energy for combined power generation in the preferred embodiment of the present invention is as follows Figure 1 As shown, see Figure 2-3 , including a camera 1, an energy storage module 2, a main control module 3, a column 4, a wind power generation mechanism 5, a hydropower generation mechanism 6, a nano friction generator 7 and a solar power generation mechanism 8; wherein, The wind power generation mechanism 5 includes a horizontal cylinder 51 arranged on the top of the column 4, and a wind energy generator 52 arranged in the cylinder 51. The front end of the cylinder 51 is provided with a trumpet-shaped wind bucket 53, and the rear end is connected with a hollow tail 54. The wind energy generator 52 includes a main body 521, a rotating shaft 522 arranged on the main body 521, and a fan blade 523 arranged on the rotating shaft 522. The cylinder 51 is rotatably connected to the column 4; The hydroelectric power generation assembly 6 includes a trumpet-shaped water bucket 61, a hydraulic driving wheel 62 arranged on the rotating shaft of the wind energy generator 52, and a hydraulic generator 63 arranged in the central inner cavity of the column 4. The upper side of the cylinder 51 is formed with an inclined water inlet pipe 64 connected to the water bucket 61, and the lower side is formed with a water outlet pipe 66 connected to the central inner cavity of the column 4. The water bucket 61 is fixedly connected to the water inlet pipe 64, and the inner cavity of the water inlet pipe 64 is inclined in the direction of rotation of the hydraulic driving wheel 62; the hydraulic driving wheel 62 includes an outer rotating wheel 621, an inner rotating wheel connected to the rotating shaft 522 for unidirectional rotation, and a plurality of connecting rods 622 for connecting the inner rotating wheel and the outer rotating wheel 621. A plurality of support plates 623 for receiving water flow are evenly distributed on the outer side of the outer rotating wheel 621, and a water trough is formed on the support plate 623; The nano friction generator 7 is fixed on the upper part of the water bucket 61 and is located on the side away from the wind bucket 53. The direction facing the front side of the nano friction generator 7 is the same as the direction of the wind bucket 53. A convex block 71 with a narrow upper part and a wide lower part is formed on the front side surface of the nano friction generator 7, and a depression is formed in the middle of the convex block 71. The output ends of the wind power generation mechanism 5, the hydropower generation mechanism 6, the friction energy generation mechanism 7 and the solar power generation mechanism 8 are all connected to the input end of the energy storage module 2, so as to input the electric energy into the energy storage module 2; The energy storage module 2 is used to supply power to the main control module 3 and the camera 1 .

[0021] The present invention can generate electricity at multiple levels under various weather conditions. When the wind starts to blow, the tail wing senses the wind direction and automatically adjusts the cylinder on the column so that the wind bucket faces the wind direction to maximize wind energy capture. The wind bucket gathers wind power into the cylinder, and the wind power drives the fan blades in the cylinder to rotate through the wind bucket. The fan blades are attached to the rotating shaft, and the rotation of the rotating shaft drives the generator inside the wind generator to generate electricity. At this time, the friction energy power generation plate can also generate electricity when facing the wind.

[0022] On rainy days, the trumpet-shaped water bucket collects rainwater and guides it to the hydraulic drive wheel through the water inlet pipe. The convex block of the friction energy power generation plate is also conducive to gathering rainwater. The water flow impacts the support plate on the hydraulic drive wheel, pushing the support plate and the outer wheel to rotate. The outer wheel is connected to the inner wheel through a connecting rod, and the inner wheel is unidirectionally connected to the shaft of the wind turbine generator. The shaft of the wind turbine generator is only driven to rotate when there is water flow, which increases the power generation efficiency. Since the hydraulic drive wheel and the shaft are unidirectionally connected, the fan blades drive the shaft to rotate when there is no water, which will not cause the hydraulic drive wheel to rotate. When there is water, the rotation of the hydraulic drive wheel will drive the shaft to rotate, thereby driving the wind turbine to generate electricity. After the water flows from the outlet pipe into the central inner cavity of the column, the hydraulic generator therein generates electricity through the drop of rainwater. An energy storage mechanism can be set to release the mechanical energy of the power drive wheel when the fan blades drive the shaft to rotate at an insufficient speed. This mechanism can store energy when the wind is sufficient and release energy when the wind is insufficient to maintain the continuous operation of the power generation system. Energy storage mechanisms that can be used include flywheels, springs, or compressed air systems. Flywheels are particularly suitable for wind power generation systems because of their high energy density and fast response. The energy storage mechanism should be set in the shaft system of the fan blades, which can be a flywheel coaxial with the shaft. When the wind is strong, it stores energy through additional rotational inertia and releases it when the wind weakens. The main control module monitors the wind speed and the speed of the shaft to decide when to store energy and when to release energy to ensure the optimal operation of the power generation system. When the wind is sufficient and the fan blade drives the shaft speed exceeding the minimum required power output speed, the control system instructs the energy storage mechanism (such as a flywheel) to start storing energy. The speed of the flywheel will increase due to the additional kinetic energy, thereby storing energy. When the wind is not enough to maintain the required power generation speed, the control system will instruct the energy storage mechanism to release the previously stored energy. The rotational kinetic energy of the flywheel is converted into mechanical energy, and the speed of the shaft is increased by coupling with the main shaft, thereby maintaining or increasing the output of the generator. The energy storage mechanism can continuously regulate the storage and release of energy, dynamically balancing power generation according to real-time wind speed and power demand, which helps reduce fluctuations in power output and provide a smoother power supply.

[0023] The inner cavity of the water inlet pipe 64 is designed to be inclined toward the direction of rotation of the hydraulic drive wheel 62, and the lower end of the water inlet pipe is located on one side of the hydraulic drive wheel. This is a design that optimizes water flow dynamics. Specifically, when the hydraulic drive wheel is required to rotate clockwise, the water outlet at the lower end of the water inlet pipe is located on the right side of the hydraulic drive wheel. Figure 3As shown, if the hydraulic drive wheel needs to rotate counterclockwise, the water outlet at the lower end of the water inlet pipe is located on the left side of the hydraulic drive wheel. Such a design can enhance the impact force of the water flow on the hydraulic drive wheel, thereby improving the power generation efficiency. When the inner cavity of the water inlet pipe 64 is inclined toward the rotation direction of the hydraulic drive wheel 62, the water flow forms a smoother linear dynamic in the pipe, which can reduce the eddy current and turbulence of the water flow when entering the water wheel, making the water flow more concentrated and stable. The inclined water inlet pipe allows the water flow to impact the water wheel at a certain angle, which not only increases the water flow thrust received by the water wheel, but also can use the kinetic energy of the water flow to more effectively convert into mechanical rotation energy. The direct and inclined impact of the water flow enables each blade of the water wheel to obtain greater driving force. The consistency of the inclination direction of the water inlet pipe and the rotation direction of the water wheel helps to improve the starting and operating efficiency of the water wheel. This design reduces the resistance of the water flow to the starting and operating of the water wheel, so that the water wheel can maintain stable operation even when the water flow is weak.

[0024] In windy or rainy environments, wind and rain come into contact with the front surface of the nano friction generator, generating friction, which is converted into electrical energy to provide additional power support for the system.

[0025] Therefore, the present invention utilizes multiple renewable energy sources to generate electricity, reduces dependence on a single energy source, and improves the energy supply security and reliability of the system. Comprehensively utilize natural energy, reduce environmental pollution, and have low long-term operating costs. The combined use of multiple energy sources ensures stable power output under different weather conditions, and is particularly suitable for use in remote areas or areas with complex natural conditions. The system intelligently adjusts the operating status of the power generation mechanism through the main control module to maximize power generation efficiency. The present invention fully considers the variability of the natural environment, and achieves efficient and sustainable energy utilization by integrating multiple power generation technologies. It is very suitable for use in the fields of monitoring and security, especially in areas with limited resources or unstable electricity.

[0026] like Figure 1-3As shown, the cylinder 51 is provided with a flange 511 corresponding to the hydraulic drive wheel 62, and the flange 511 is provided with a groove 512 for accommodating the outer rotating wheel 621 and the support plate 623, and the water inlet pipe 64 and the water outlet pipe 62 are both located in the groove 512. The flange 511 is arranged on the surface of the cylinder 51, and its purpose is to provide a special positioning point for the hydraulic drive wheel 62, which helps to ensure the stable operation of the hydraulic drive wheel. The groove 512 is located inside the flange 511 and is specifically used to accommodate the outer rotating wheel 621 and the support plate 623. The design of the groove not only helps to protect these components from external physical influences, but also reduces the wind resistance of the system during operation, because the rotating wheel and the support plate are partially or completely located inside the flange. The water inlet pipe and the water outlet pipe 66 are both located in the groove 512. Such a layout makes the flow path of rainwater more concentrated and efficient, reduces the loss of water flow, and ensures that every drop of rainwater can be effectively converted into power. There are preferably four connecting rods, which are used to connect the inner and outer rotors, ensuring structural stability while minimizing the impact on the wind duct. The appropriate number of connecting rods is selected to balance structural strength and air flow efficiency. Through the optimized layout in the groove, the flow resistance of air and water flow is reduced, allowing wind and hydropower generation mechanisms to operate with lower energy loss. The integrated design makes the overall equipment more compact, easy to install and maintain, and also improves the aesthetics of the equipment. The groove 512 provides a certain degree of protection for the outer rotor 621 and the support plate 623 to prevent damage under severe weather conditions and extend the service life of the equipment.

[0027] There are two solutions for the one-way connection between the inner wheel and the shaft: First, if Figure 2-3 As shown, the inner rotating wheel includes a passive wheel 624 fixedly connected to the rotating shaft 522, and a driving wheel 625 connected to the rotating shaft 522 through a bearing, an inner ratchet structure 626 is formed on one side of the driving wheel 625, and a ratchet pawl 627 corresponding to the inner ratchet structure 626 of the driving wheel 625 is provided on the passive wheel.

[0028] Second, the inner rotating wheel is connected to the rotating shaft 522 via a one-way bearing.

[0029] The passive wheel 624 is fixedly connected to the rotating shaft 522 and is directly driven by the blades of the wind energy generator. When it rotates, it drives the rotating shaft 522 to rotate. When it is driven by the rotating shaft 522, it will not affect the driving wheel 625. The driving wheel 625 is connected to the rotating shaft 522 through a bearing, allowing it to rotate freely relative to the rotating shaft, thereby reducing friction and wear, and improving the durability and efficiency of the entire system. An inner ratchet structure 626 is formed on one side of the driving wheel 625, which is a mechanism that allows the wheel to rotate freely in one direction and lock in another direction. A ratchet 627 corresponding to the inner ratchet structure 626 is provided on the passive wheel 624, and only when the rotation direction of the driving wheel 625 is consistent with the rotation direction of the passive wheel 624 will it be embedded and drive the passive wheel 624 to rotate. When the wind force or water force is sufficient to drive the driving wheel 625, the ratchet 627 is embedded in the inner ratchet structure 626 of the driving wheel 625, so that the driving wheel 625 and the passive wheel 624 rotate synchronously, effectively transmitting power to the wind energy generator or hydropower generation component.

[0030] When there is no external power (such as water flow) to push, the driving wheel 625 can be unaffected by the movement of the passive wheel 624 and the rotating shaft 522 under the action of the bearing, which means that the efficiency of the system will not be affected when wind power is used alone to generate electricity. Through this one-way transmission design, the system can more flexibly adapt to different environmental conditions (such as wind power alone or wind power plus water power), while maximizing the overall power generation efficiency without sacrificing any energy source. This design also helps to reduce energy loss caused by mutual interference between rotating parts, further improving the overall efficiency of the system. Using bearings to connect the driving wheel can reduce wear caused by long-term operation and improve the reliability and life of the equipment.

[0031] like Figure 2 As shown, the solar power generation mechanism 8 includes a solar panel 81 and a driving mechanism 82. The solar panel 81 is connected to the column 4 through the driving mechanism 82. The driving mechanism 82 is used to adjust the direction and angle of the solar panel 81. The main control module is used to calculate the direction of the sun and the change value of the angle between the sun and the ground at a preset frequency, rotate the solar panel 81 to the direction of the sun through the driving mechanism, and adjust the angle of the solar panel 81 so that the front of the solar panel 81 is opposite to the sun.

[0032] The solar panel 81 is the main component that captures sunlight and converts it into electrical energy. The drive mechanism 82 is a movable connection mechanism that connects the solar panel 81 to the column 4 and allows the solar panel to be adjusted in the vertical and horizontal directions to track the position of the sun. The main control module calculates the direction of the sun and the change in the angle with the ground according to the preset algorithm frequency. These calculations are based on factors such as geographical location, date and time. After receiving the data of the sun's position, the main control module controls the solar panel 81 through the drive mechanism 82 to rotate it to the optimal light-collecting angle. The drive mechanism 82 automatically adjusts the direction and tilt angle of the solar panel 81 according to the instructions of the main control module to ensure that the solar panel is always facing the sun and maximizes the photoelectric conversion efficiency. By intelligently tracking the position of the sun, the solar panel can maintain the optimal light-collecting angle at any time of the day, thereby significantly improving the power generation efficiency. The automatic tracking system reduces the need for manual adjustment and improves the convenience and energy efficiency of the system. By optimizing the position of the solar panel, solar energy can be used more effectively, which is particularly important in a multi-energy power generation system because it ensures the maximization of solar power generation when wind energy, hydropower or other energy sources are insufficient. The intelligent adjustment mechanism ensures that the system can operate continuously and stably under various climate and sunshine conditions.

[0033] The driving mechanism 82 includes a motor 821, and a longitudinal first bevel gear 822 connected to the output end of the motor 821, the column 4 is connected to a transverse second bevel gear 823 through a bearing, the camera 1 is fixed to the second bevel gear 823 through a bracket, the column is connected to a transverse steering wheel 824 through a bearing, the solar panel is arranged on the steering wheel 824, the second bevel gear is provided with an electric telescopic rod 825, and the steering wheel 824 is annularly distributed with a plurality of steering grooves corresponding to the electric telescopic rod 825. The solar panel is connected to the steering wheel through an angle adjustment mechanism, and the angle adjustment mechanism is electrically connected to the main control module for controlling the angle of the solar panel. The angle adjustment mechanism can be a gear transmission mechanism, or a sliding bearing mechanism, a spring mechanism, an electromagnetic mechanism, etc., as long as the angle adjustment can be achieved.

[0034] The motor 821 is used as a power source, and the motor 821 is responsible for driving the rotation and adjustment of the entire system. The first bevel gear 822 is connected to the output end of the motor 821. This longitudinal bevel gear transmits the rotational power of the motor to the horizontal second bevel gear 823. The second bevel gear 823 is installed on the column 4 through a bearing, receives the power from the first bevel gear, and supports the bracket of the camera 1. The first bevel gear is driven by the motor to drive the second bevel gear, allowing the camera to rotate 360 ​​degrees around the column as the center, ensuring a wide coverage of the monitoring range. The steering wheel 824 is set under the solar panel and connected to the column through a bearing. The annular steering groove on the steering wheel corresponds to the electric telescopic rod 825, allowing the solar panel to be accurately adjusted in the horizontal plane. The electric telescopic rod 825 extends from the second bevel gear to accurately control the position of the steering wheel 824. When the solar panel needs to adjust the angle to align with the sun, the electric telescopic rod will extend, and the front end will be inserted into the steering groove on the steering wheel. As the first bevel gear rotates, the steering wheel is driven to rotate through physical cooperation, thereby adjusting the direction of the solar panel. The system integrates the positioning and adjustment of the camera and solar panel into the same drive mechanism, which improves the coordinated efficiency and ease of operation of the equipment. Through the main control module to control the operation of the motor and the electric telescopic rod, the system can automatically adjust the position of the solar panel and the camera to ensure that the solar panel always captures the sunlight at the best angle, while the camera covers the key monitoring area. The combination of the electric telescopic rod and the steering slot allows the solar panel to be fine-tuned when necessary, making energy capture more efficient, while also ensuring that the camera's monitoring angle is accurately focused. This design not only improves the energy efficiency of the solar panel, but also enhances the flexibility and response speed of the monitoring system, enabling it to better adapt to different environmental conditions and monitoring needs.

[0035] The upper opening of the water bucket 61 is formed with an arc corresponding to the protrusion. The arc opening design helps to more effectively capture and guide rainwater or other water sources directly into the water bucket 61. The area for water flow to enter can be increased to ensure that water resources can be collected to the maximum extent even in strong winds or slanting rain. The arc opening of the water bucket 61 matches the shape of the protrusion 511, ensuring accurate alignment and connection between the water bucket and other system components (such as the hydraulic drive wheel or other structure on the protrusion), thereby improving the overall structural stability and functional synergy.

[0036] When rainwater enters from the arc-shaped opening of the water bucket 61, it flows directly to the structure corresponding to the protrusion 511, such as the hydraulic drive wheel. Such a design reduces the energy loss of water flow during the transmission process and improves the efficiency of hydroelectric power generation.

[0037] like Figure 2As shown, a water storage chamber 41 is formed in the column 4, and the water storage chamber 41 is provided with a water outlet and a water inlet, the water inlet is connected to the central inner cavity of the column 4, and a solenoid valve is provided on the water outlet; a heat sink is provided on the energy storage module 2, and heat sink fins 21 are provided on the heat sink, and the water outlet is connected to a hose and the outlet of the hose is located above the heat sink fins 21.

[0038] The hose guides the water in the water tank through the outlet and directs it over the cooling fins on the heat sink. When the water flows through the heat sink fins, it takes away the heat generated by the heat sink, thereby reducing the temperature of the energy storage module and further improving the heat dissipation efficiency. The energy storage module generates a lot of heat during operation, especially under high load conditions. If the temperature is too high, it may affect the performance and life of the module. Through this water cooling mechanism, the temperature of the energy storage module can be effectively controlled to prevent overheating.

[0039] The solenoid valve can accurately control the flow of water in and out. By adjusting the opening time or opening degree of the solenoid valve, the water level in the water tank can be accurately controlled. The solenoid valve can be set to automatically close under abnormal conditions (such as excessive water pressure, system failure) to prevent water overflow or system damage and ensure system safety.

[0040] like Figure 2 As shown, a sleeve 55 sleeved on the column 4 is fixed to the lower side of the cylinder 51, and the sleeve 55 is rotatably connected to the column 4 through a bearing. A waterproof rubber ring is provided at the connection between the central inner cavity of the column 4 and the water outlet pipe 62, a gear is fixed on the sleeve, and an electric limit mechanism for limiting the rotation of the gear is provided on the column.

[0041] The sleeve 55 is sleeved on the column 4 and is rotatably connected to the column through a bearing, so that the cylinder 51 can rotate smoothly under the action of wind force to track the wind direction while maintaining the stability of the overall structure. The use of bearings reduces friction during rotation and ensures the smoothness of rotation, thereby improving power generation efficiency and reducing maintenance costs. A waterproof rubber ring is provided at the connection between the central inner cavity of the column 4 and the water outlet pipe 62 to prevent water from flowing out of the connection between the central inner cavity and the water outlet pipe 62. The gear fixed on the sleeve cooperates with the electric limit mechanism on the column. When the wind direction is determined, the electric limit mechanism can lock the position of the gear to prevent the cylinder from swinging or over-rotating in strong winds, thereby reducing the dynamic load caused by changes in wind direction.

[0042] The electric limit mechanism includes a small electric motor to drive the activation and release of the limit mechanism. The motor can respond quickly based on the signal from the main control module. It also includes a set of limit switches, which are set at key positions of the gear or rotating structure. When the gear reaches the preset maximum or minimum rotation range, the limit switch is triggered and sends a signal to the main control module. Once the limit switch is triggered, the locking mechanism is activated, which can include a mechanical lock, electromagnetic lock or other type of blocking device to fix the position of the gear and prevent further rotation. The electric limit mechanism is equipped with sensors or other feedback devices that can monitor and report the position and status of the gear in real time to ensure the accuracy of system control. When the system needs to fix the position of the wind turbine to cope with changes in wind direction, the main control module determines the position where the cylinder needs to be locked based on the data from the wind direction sensor. After receiving the signal, the electric motor of the electric limit mechanism starts and drives the locking mechanism to lock the gear in the appropriate position. Once the gear is locked, any additional rotation or vibration caused by wind will not affect the positioning of the cylinder, maintaining the optimization of power generation efficiency.

[0043] By precisely controlling the rotation and fixation of the cylinder, the system can operate stably in the best wind direction and improve the utilization rate of wind energy. The use of waterproof rubber rings enhances the resistance of the entire system to bad weather, especially in environments where rain may invade. The use of electric limit mechanisms reduces the risk of equipment damage caused by excessive wind force, extends the service life of the equipment and reduces maintenance costs. The system can maintain stable output in an environment with large wind changes, ensuring the continuity and reliability of energy supply.

[0044] like Figure 1-2 As shown, the energy storage module 2 includes a switching module and a battery module. The output end of the solar panel 81 is connected to the switching module. When it is detected that the current output by the solar panel 81 is lower than the current required by the camera 1, the switching module switches to the battery to power the camera 1.

[0045] In summary, the camera of the present invention, which uses wind energy, rainwater energy, friction energy and solar energy for composite power generation, significantly improves the energy utilization efficiency and the automation level of the system. By integrating wind power, water power, friction energy and solar power generation mechanisms, it can continuously generate electricity under different weather conditions, greatly enhancing the sustainability of energy and the stability of power supply. The intelligent positioning system of the solar panel and the automatic rotation mechanism of the camera, through the precise calculation and control of the main control module, achieve rapid response to environmental conditions and optimal energy capture. The special design of the water bucket optimizes the collection and guidance of rainwater and reduces the loss in the energy conversion process. The tail wing and wind bucket design of the wind power generation mechanism also ensure the maximum capture of wind power. Through carefully designed components and mechanisms, such as the bevel gear structure of one-way transmission, the mechanical efficiency and long-term operation reliability of the system are improved. The design takes into account different climatic and geographical conditions to ensure that the system can work effectively in a changing environment, and is particularly suitable for use in areas with complex natural conditions or limited infrastructure. The use of renewable energy reduces dependence on fossil fuels and reduces environmental pollution. The efficient energy conversion and intelligent management of the system also reduce the maintenance and energy costs of long-term operation.

[0046] In summary, the present invention combines modern intelligent technology and multi-energy management, which not only enhances the functionality of the monitoring system, but also improves the efficiency of energy utilization and environmental sustainability. While providing security monitoring, this system can also serve as an ideal energy solution for smart cities, remote areas or environmental monitoring sites.

[0047] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
