Description

Technical Field

[0001] This invention belongs to the field of wind power generation technology, and particularly relates to a structure and method for adjusting the angle of photovoltaic modules on a wind turbine tower. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source, making it very environmentally friendly. Moreover, wind energy reserves are enormous, so it is receiving increasing attention from countries around the world. The process of wind power generation is to convert the kinetic energy of wind into mechanical kinetic energy, and then convert mechanical energy into electrical kinetic energy. The principle of wind turbine generators is to use wind power to drive the windmill blades to rotate, and then use a speed increaser to increase the rotation speed to drive the generator to generate electricity.

[0003] The wind turbine tower is the support structure for wind power generation. The photovoltaic panels, installed on top of the tower, function as energy absorption devices for the drive unit. The problems with this technology are: the photovoltaic panels are exposed on the top of the tower, making them prone to accumulating dust and dirt. The tower's height makes cleaning difficult. Furthermore, the panels are fixed to the tower via a support frame and multiple threaded components, and the fixed angle of the support frame prevents adjustment based on varying solar intensity throughout the season, leading to inconvenience in use. Summary of the Invention

[0004] In view of the problems existing in the prior art, the present invention provides a structure and method for adjusting the angle of photovoltaic modules on wind turbine towers that can overcome or at least partially solve the above problems.

[0005] The present invention is implemented as follows: a structure and method for adjusting the angle of a photovoltaic module on a wind turbine tower, wherein the structure includes a photovoltaic panel, a base, a fixing rod and a support rod, the base is located at the bottom of the photovoltaic panel, the fixing rod is fixedly installed on the right side of the photovoltaic panel, the inner cavity on the left side of the support rod is in contact with the surface of the fixing rod, and the inner cavity of the fixing rod is provided with a placement groove.

[0006] The inner cavity of the placement slot is provided with a positioning mechanism that works in conjunction with the support rod;

[0007] The inner cavity of the placement slot is provided with a transmission mechanism that works in conjunction with the positioning mechanism;

[0008] The top of the support rod is equipped with a cleaning mechanism that works in conjunction with the photovoltaic panel;

[0009] The top of the base is equipped with an adjustment component for use with the photovoltaic panel.

[0010] To improve the ease of assembling the cleaning components, the positioning mechanism preferably includes two positioning rods. A pressing rod is fixedly connected to the left side of each positioning rod, and a tension spring is fixedly connected to the opposite side of each positioning rod. The side of the tension spring closest to the inner wall of the placement slot is fixedly connected to the inner wall of the placement slot. A limiting rod is movably connected to the inner cavity of each positioning rod. The top and bottom of the limiting rod are fixedly connected to the inner wall of the placement slot. By setting up the positioning mechanism, the positioning rods can achieve the effect of quickly installing the cleaning mechanism through the cooperation of the fixing and support rods.

[0011] To improve the stability of the positioning mechanism, the transmission mechanism preferably includes a movable block. The top and bottom of the movable block are in contact with the surface of the extrusion rod. A spring is fixedly connected to the left side of the movable block, and the left side of the spring is fixedly connected to the inner wall of the placement groove. A guide block is movably connected to the inner cavity of the movable block, and the left side of the guide block is fixedly connected to the inner wall of the placement groove. A transmission rod is fixedly connected to the front side of the movable block, and the front side of the transmission rod passes through the fixed rod and extends to the outside of the fixed rod. By setting the transmission mechanism, the movable block can quickly drive the positioning rod to move by cooperating with the extrusion rod, avoiding the situation where the support rod cannot be disengaged from the fixed state when the cleaning mechanism needs to be disassembled for cleaning.

[0012] To improve the ease of cleaning photovoltaic panels, the cleaning mechanism preferably includes a servo motor. A sleeve is fixedly installed at the output end of the servo motor, and a moving block is fixedly installed on the left side of the sleeve. A sponge is embedded in the inner cavity at the bottom of the moving block, and the bottom of the sponge is horizontally aligned with the top of the photovoltaic panel. A column is fixedly connected to the right side of the servo motor, and the bottom of the column is fixedly connected to the top of the support rod. By setting up the cleaning mechanism, the cleaning mechanism can achieve the effect of quickly wiping the surface of the photovoltaic panel through the sponge by the cooperation of the servo motor, the sleeve, and the moving block.

[0013] To improve the ease of adjustment of the photovoltaic panel, the adjustment component preferably includes a rotary motor. An arc rod is fixedly connected to the output end of the rotary motor, and a tray is fixedly connected to the top of the arc rod. The top of the tray is fixedly connected to the bottom of the photovoltaic panel. A controller is fixedly installed on the front side of the rotary motor and is electrically connected to the rotary motor. By setting the adjustment component, the adjustment component can achieve the effect of quickly adjusting the photovoltaic panel through the cooperation of the controller, the rotary motor, the arc rod, and the tray.

[0014] To improve stability during photovoltaic panel adjustment, it is preferable that toothed discs are fixedly connected to both the left and right sides of the bottom of the arc rod, and a limiting disc is movably connected to the bottom of the two toothed discs. The inner cavity of the limiting disc meshes with the surface of the two toothed discs. A cylindrical rod is fixedly connected to both the left and right sides of the bottom of the limiting disc, and the bottom of the cylindrical rod is fixedly connected to the top of the base. The output end of the rotary motor contacts the inner cavity of the limiting disc. By setting the toothed discs, limiting discs, and cylindrical rods, the cylindrical rods can achieve the effect of stable support for the limiting discs through cooperation with the base. The limiting discs, through the cooperation of the toothed discs and the arc plate, assist the arc plate and the tray in stable rotation.

[0015] To improve stability during the cleaning process of photovoltaic panels, it is preferable that locking blocks are fixedly connected to both the front and rear sides of the photovoltaic panel. A guide rod is fixedly connected to the inner cavity of the locking block, and a slider is sleeved on the surface of the guide rod. The top of the slider is movably connected to the inner cavity of the moving block. By setting the locking block, guide rod, and slider, the locking block can assist the moving block in moving stably through the cooperation of the guide rod and slider, avoiding the moving block from causing the sponge to shake during the movement, thus affecting the stable wiping effect on the photovoltaic panel.

[0016] To improve the assembly effect of the fixing rod and the support rod, it is preferable that the fixing rod has connecting holes at the top and bottom, and the support rod has positioning grooves at the top and bottom of its inner cavity. The opposite sides of the two positioning rods pass through the connecting holes and extend into the inner cavity of the positioning grooves. By setting the connecting holes and positioning grooves, the connecting holes enable the positioning rods to quickly align with the positioning grooves.

[0017] To improve the ease of use of photovoltaic panels, the following method is adopted: First, pull the transmission rod. The transmission rod will drive the movable block to move and compress the spring. During the movement, the movable block will compress the spring and contact the surface of the pressing rod, applying force. After the pressing rod is subjected to force, it will drive the positioning rod to move. The positioning rod will stretch the tension spring during its movement. After the positioning rod moves to the appropriate position, the cleaning mechanism can be removed for cleaning. After cleaning, the support rod and the fixing rod are reconnected. During the connection process, the cleaning mechanism needs to be horizontally aligned with the photovoltaic panel. After the connection is completed, release the transmission rod. The spring force will rebound and quickly drive the movable block to reset. During the reset process, the pressing rod will lose its force. After the pressing rod loses its force, the tension spring will contract, quickly driving the positioning rod to insert into the inner cavity of the positioning groove. After insertion into the inner cavity of the positioning groove, the cleaning mechanism can be quickly fixed by the support rod, thus completing the convenient cleaning and quick assembly of the cleaning mechanism.

[0018] Step 2: After the cleaning mechanism is fixed in place, the sleeve can be extended or retracted by a servo motor. During this extension or retraction, the sleeve can move the moving block and the sponge, which are horizontally aligned with the photovoltaic panel. Therefore, as it slides downwards, it will come into contact with the surface of the photovoltaic panel, thereby achieving a rapid cleaning effect on the surface of the photovoltaic panel.

[0019] Step 3: After cleaning the photovoltaic panel, the controller can drive the rotary motor to run. During the operation of the rotary motor, the tray can be rotated through the arc plate, so as to achieve the effect of convenient adjustment of the photovoltaic panel according to the intensity of sunlight in the region or the current season. In addition, the arc plate will improve the rotational stability of the photovoltaic panel during the adjustment process through the cooperation of the toothed plate and the limit plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention comprises a photovoltaic panel, a base, a fixing rod, a support rod, a placement slot, a positioning mechanism, a transmission mechanism, a cleaning mechanism, and an adjustment component. After the cleaning mechanism is secured by the transmission mechanism, positioning mechanism, fixing rod, and support rod, a servo motor drives a sleeve to extend and retract. During this extension and retraction, the sleeve drives a moving block and a sponge to slide, with the sponge horizontally aligned with the photovoltaic panel. Therefore, during downward sliding, the sponge makes contact with the surface of the photovoltaic panel, achieving rapid cleaning. After cleaning the photovoltaic panel, a controller drives a rotary motor. During operation, the rotary motor rotates a tray via an arc-shaped plate. This design allows for convenient adjustment of the photovoltaic (PV) panels based on the intensity of sunlight in a given region or season. The curved plate, through the interaction of the gear plate and the limiting plate, enhances the rotational stability of the PV panels during adjustment. This addresses the issue of PV panels being installed on top of wind turbine towers and exposed to the outside, where dust and dirt easily accumulate. Furthermore, the height of wind turbine towers makes cleaning difficult for users. Additionally, the fixed angle of the support frame, secured to the top of the wind turbine tower by multiple threaded components, prevents adjustment based on seasonal sunlight intensity, resulting in inconvenience during use.

[0037] Working principle of the invention:

[0038] In use, pulling the transmission rod 704 causes the movable block 701 to move and compress the spring 702. During this movement, the movable block 701 compresses the spring 702 and comes into contact with the surface of the pressing rod 602, applying force.
