Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and in particular to a vehicle-mounted wind power generation device. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source that has long been used, primarily through windmills for pumping water and grinding flour. However, interest in harnessing the wind to generate electricity has grown. Wind power generation is environmentally friendly and possesses enormous potential, earning it increasing attention worldwide. However, wind turbines currently used in vehicles often fail to adjust their blades based on vehicle speed. At slower speeds, the larger blades are less likely to be blown, while at faster speeds, the blades are unable to store as much kinetic energy, resulting in lower power generation efficiency. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides a vehicle-mounted wind power generation device, which solves the problem that the wind power generation devices currently used in vehicles are usually unable to adjust the fan blades according to the speed of the vehicle. When the vehicle is traveling at a slow speed, the larger fan blades are not easily blown, and when the vehicle is traveling at a fast speed, the fan blades cannot store more kinetic energy, resulting in low power generation efficiency.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A vehicle-mounted wind power generation device, specifically comprising:

[0005] A power generation box, wherein a rotating device is provided inside the power generation box, and both ends of the inner wall of the power generation box are fixedly connected to the power generation device;

[0006] An air inlet device is provided at the bottom of the generator box, and one end of the air inlet device is connected to the interior of the generator box;

[0007] An air outlet is provided on the top of the generator box, and one end of the air outlet is connected to the interior of the generator box;

[0008] The rotating device comprises:

[0009] A rotating shaft, a storage sleeve is sleeved and fixedly connected to the outer side of the rotating shaft, and a storage cavity is defined in the storage sleeve;

[0010] An arc-shaped air plate, one end of which passes through the receiving sleeve and extends into the receiving cavity, and one end of the arc-shaped air plate located inside the receiving cavity is fixedly connected to a counterweight block;

[0011] A tensioning spring is provided inside the receiving cavity, one end of the tensioning spring is fixedly connected to the side of the counterweight, and the end of the tensioning spring away from the counterweight is fixedly connected to the inner wall of the receiving cavity;

[0012] An arc-shaped baffle, one side of which is fixedly connected to an end of the arc-shaped air plate located outside the receiving cavity.

[0013] A rotating device is provided. When the vehicle is traveling, wind enters the generator box from the air inlet device, which can drive the curved wind plate inside the generator box to rotate. The curved wind plate drives the storage sleeve and the rotating shaft to rotate, and the generator device can be driven to generate electricity through the rotating shaft. When the vehicle is traveling at a faster speed, the wind speed is larger, the curved wind plate rotates faster, the centrifugal force increases, and the curved wind plate is driven to extend from the inside of the storage cavity. The longer the length of the extended curved wind plate, the greater the rotational inertia. When the wind speed decreases, it can rotate for a longer time by inertia, which is convenient for maintaining efficient power generation for a longer time, thereby improving power generation efficiency. When the wind speed is low, the curved wind plate enters the storage cavity under the elastic force of the tightening spring, and the center of gravity of the curved wind plate can be moved toward the direction of the rotating shaft, so that the curved wind plate can rotate under a smaller wind pressure, can automatically adapt to changes in vehicle speed, and has a higher power generation efficiency.

The air intake pipe inside the air intake device is set to be L-shaped, so that when it rains outside, rainwater will not pass through the inside of the air intake pipe fastening device, which is convenient for protecting the internal components of the device. When wind enters the inside of the air intake pipe from one end of the air intake pipe, it first passes through the drying cotton strip on the fixed column machine, and the air coming in from the outside can be dried by the drying cotton strip, and small water droplets contained in the air are adsorbed, which has a better waterproof effect.

[0017] Preferably, the air inlet pipe is configured to be L-shaped, one end of the air inlet pipe away from the filter device is connected to the bottom of the generator box, and the connection between the air inlet pipe and the generator box is staggered with the central axis of the generator box.

[0018] Preferably, the rotating seat is arranged at the bend of the air inlet pipe, and the drying slivers include tall slivers and short slivers that are staggered. A rotating seat and a fixed column are provided. When the air flow flows inside the air inlet pipe, the drying slivers of different heights can be blown to drive the fixed column to rotate. When the fixed column rotates, the drying slivers at different positions can be rotated to the windward side for adsorption, so that the drying slivers on the fixed column can be dried evenly, and the drying effect is better.

[0022] The present invention provides a vehicle-mounted wind power generation device having the following beneficial effects:

[0023] (1) The vehicle-mounted wind power generation device is provided with a rotating device. When the vehicle is running, wind enters the generator box from the air inlet device, which can drive the arc-shaped wind plate inside the generator box to rotate. The arc-shaped wind plate drives the storage sleeve and the rotating shaft to rotate, and the generator device can be driven to generate electricity through the rotating shaft. When the vehicle is running at a faster speed, the wind speed is larger, the arc-shaped wind plate rotates faster, the centrifugal force increases, and drives the arc-shaped wind plate to extend from the inside of the storage cavity. The longer the length of the arc-shaped wind plate is extended, the greater the rotational inertia. When the wind speed decreases, it can rotate for a longer time by inertia, which is convenient for maintaining efficient power generation for a longer time and improving the power generation efficiency. When the wind speed is lower, the arc-shaped wind plate enters the storage cavity under the elastic force of the tensioning spring, and the center of gravity of the arc-shaped wind plate can be moved toward the direction of the rotating shaft, so that the arc-shaped wind plate can rotate under a smaller wind pressure, and can automatically adapt to the change of vehicle speed, and the power generation efficiency is higher.

[0024] (2) This vehicle-mounted wind power generation device is provided with an air intake device. The air intake pipe inside the air intake device is set to be L-shaped, so that when it rains outside, rainwater will not pass through the inside of the air intake pipe fastening device, which is convenient for protecting the internal components of the device. When wind enters the air intake pipe from one end of the air intake pipe, it first passes through the drying cotton strips on the fixed column machine, and the drying cotton strips can dry the air coming in from the outside and absorb small water droplets contained in the air, so as to have a better waterproof effect.

[0025] (3) This vehicle-mounted wind power generation device is provided with a rotating seat and a fixed column. When the air flow flows inside the air inlet pipe, it can blow the drying cotton strips of different heights to drive the fixed column to rotate. When the fixed column rotates, the drying cotton strips at different positions can be rotated to the windward side for adsorption, so that the drying cotton strips on the fixed column can be dried evenly, and the drying effect is better.

[0026] (4) The vehicle-mounted wind power generation device is provided with a filtering device. The wind enters the air inlet pipe through the filtering device, and can filter out large-diameter impurities through the filter screen inside the filtering device to prevent large-diameter impurities from entering the device and damaging internal components. When the filter screen is not blocked and is in normal use, the extrusion spring pushes the filter screen on the cleaning brush through its own elastic force, so that the cleaning brush cannot rotate. When the filter screen is blocked, the wind pressure on the filter screen increases, and the wind pressure drives the filter screen to push the extrusion spring, so that the pressure of the filter screen on the cleaning brush is reduced. At this time, the air circulating in the air inlet pipe can drive the propeller fan to rotate, and the propeller fan drives the cleaning brush to rotate. The cleaning brush can clean the surface of the filter screen, which is convenient for automatic cleaning of the filter screen and avoids blockage of the filter screen surface. When the filter screen is not blocked, the cleaning brush does not rotate, which is convenient for reducing the wear of the cleaning brush. BRIEF DESCRIPTION OF THE DRAWINGS
