Description

[0001] The present invention relates to the technical field of photovoltaic solar energy, and in particular to a photovoltaic solar energy support structure with a light-chasing function and a light-chasing method thereof. Background Art

[0002] Photovoltaic power generation is based on the principle of the photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. The use of solar energy has become one of the most popular renewable energy research due to its economy, environmental protection, durability and maturity. However, the current solar energy application technology generally has the disadvantages of low utilization rate and low conversion rate. In addition, the solar panels and brackets in many occasions are fixedly installed, and the photovoltaic panels and brackets cannot actively change with the direction of the sun's radiation. However, the direction of the sun's radiation is constantly changing from morning to evening. During the use of existing photovoltaic panels and photovoltaic solar brackets, if they cope with the constantly changing direction of the sun's radiation, they cannot adjust the angle well, and cannot make the lighting surface always face the direction of the sunlight, resulting in a greatly reduced utilization rate of solar energy.

An arc groove is penetrated through the side of the light-chasing rotating seat, and the arc groove is slidably connected to the arc rod.

[0006] Preferably, a dovetail groove is provided on the side of the support base, and the locking mechanism includes an electric telescopic rod fixedly installed on the side of the support base, and a locking tooth block fixedly installed on the end of the inner rod of the electric telescopic rod, and a dovetail block is fixedly connected to the side of the locking tooth block, the dovetail block is slidably connected to the dovetail groove, and the locking tooth block is clamped with the synchronous gear ring.

[0007] Preferably, a transmission assembly is installed on the inner side of the photovoltaic support, and a protective component and a cleaning mechanism are installed on the transmission assembly.

[0008] Preferably, the transmission assembly includes two rotating shafts symmetrically rotatably connected to the two ends of the inner side of the photovoltaic bracket, and pulleys are symmetrically fixedly sleeved on both ends of the rotating shafts. Both ends of the two rotating shafts are sleeved with transmission belts, and the transmission belts are sleeved on the pulleys at the ends of the rotating shafts. A limiting support plate is symmetrically fixedly connected to the inner side of the photovoltaic bracket, and the upper end of the limiting support plate is in sliding contact with the upper end of the inner side of the transmission belt, and one of the rotating shafts is driven by the output shaft of a servo motor fixedly mounted on the side of the photovoltaic bracket.

[0009] Preferably, the protective component includes a protective cloth arranged between two conveyor belts, and the length of the protective cloth is less than half of the circumference of the conveyor belts.

[0010] Preferably, the cleaning mechanism comprises a horizontal plate fixedly mounted on the upper ends of the two conveyor belts through a connecting frame, a fixed plate fixedly mounted on the upper end of the horizontal plate, a cleaning brush movably mounted on the lower end of the horizontal plate, and a shaking mechanism mounted on the upper end of the cleaning brush; A guide groove is provided on the side of the transverse plate, and a T-shaped groove is symmetrically provided on the upper end of the transverse plate.

The rotating disk is driven by the main shaft of a waterproof motor fixedly installed on the side of the fixed plate. The shaking plate is slidably connected to the guide groove, a shaking groove is opened on the side of the shaking plate, and the transmission rod is slidably connected to the shaking groove.

[0012] A light-chasing method for a photovoltaic solar bracket with a light-chasing function, wherein the control system performs the following steps, and the control system includes a light-chasing sensor, a transceiver module, a motor control module, a potentiometer, an analysis and processing module, and a comparison and processing module; The specific steps are as follows: Step 1: Photosensitive detection, using a light-chasing sensor to detect light intensity. The photosensitive element is sensitive to changes in sunlight and adjusts its own resistance value according to the light intensity, thereby generating a corresponding current signal. The detected signal is sent to the transceiver module, which transmits the signal to the control system. The control system analyzes these signals through the analysis module to determine the illumination range of the light intensity, thereby determining the angle of the strongest light. Step 2: Drive tracking. At this time, the control system controls the electric telescopic rod to retract, so that the locking mechanism releases the lock on the synchronous gear ring, and then controls the stepper motor to rotate through the motor control module, so that the photovoltaic bracket and the light tracking sensor can rotate and adjust to achieve tracking of the light source; Step 3: Calibration and positioning. The potentiometer is used to detect the rotation angle in real time, and the actual rotation angle is sent to the comparison processing module through the transceiver module. The comparison processing module compares and analyzes the actual rotation angle of the photovoltaic bracket and the light tracking sensor with the angle calculated by the analysis module to determine whether the rotation position of the photovoltaic bracket is correct.

[0013] Step 4: Protective locking. After the tracking is completed, the control system controls the inner rod of the electric telescopic rod to extend, so that the locking mechanism locks the synchronous gear ring, thereby locking the photovoltaic bracket; Step 5: Reset. When the light-chasing sensor does not detect light for a long time, the light-chasing sensor sends a signal to the analysis module. The analysis module analyzes the signal and sends the information to the control system. The control system sends a start signal to the motor control module. The motor control module controls the stepper motor to rotate back and reset, so that the photovoltaic bracket and the light-chasing sensor return to the initial position, that is, the photovoltaic bracket and the light-chasing sensor rotate to the east position.

[0014] Preferably, if there is a deviation in the actual rotation position angle in step three, the control system controls the rotation of the stepper motor through the motor control module, thereby rotating and adjusting the photovoltaic bracket and the light tracking sensor until the actual rotation position angle is the same as the angle calculated by the analysis module.

[0015] Compared with the prior art, the invention has the following advantages: 1. The strongest light angle is detected in real time by the light-chasing sensor, so that the motor shaft of the stepper motor drives the main gear to rotate, and the light-chasing rotating seat drives the photovoltaic solar panel and the light-chasing sensor to rotate through the photovoltaic bracket, thereby adjusting the position of the photovoltaic solar panel so that the strongest light can be vertically irradiated on the photovoltaic solar panel, thereby improving the efficiency of lighting.

[0016] 2. The position of the photovoltaic solar panel is adjusted by cooperating with the setting light-chasing sensor and the control system. The potentiometer, analysis and processing module and comparison processing module in the control system can detect in real time whether the actual rotation position of the photovoltaic solar panel is correct, ensuring that the strongest light can be irradiated on the photovoltaic solar panel as vertically as possible, thereby improving the efficiency of lighting.

[0017] 3. When the light-chasing rotating seat needs to rotate, the inner rod of the electric telescopic rod contracts to separate the locking tooth block from the synchronous gear. When the photovoltaic solar panel is adjusted, the inner rod of the electric telescopic rod extends to engage the locking tooth block with the synchronous gear, so that the locking mechanism locks the synchronous gear and locks the light-chasing rotating seat and photovoltaic bracket at the same time, so that the photovoltaic solar panel can receive light.

[0018] 4. When there is severe weather such as strong winds, in order to prevent the photovoltaic solar panels from being damaged by foreign objects, the conveyor belt drives the protective components to rotate above the photovoltaic solar panels, thereby protecting the photovoltaic solar panels.

[0019] 5. When it is necessary to clean the dust and other debris on the upper end of the photovoltaic solar panel, the cleaning mechanism is driven to move along the upper end of the photovoltaic solar panel by the movement of the conveyor belt, and the waterproof motor is started at the same time to make the cleaning brush move back and forth left and right along the upper end of the photovoltaic solar panel, thereby cleaning the dust and other debris on the upper end of the photovoltaic solar panel, thereby improving the effect of cleaning the dust and other debris on the upper end of the photovoltaic solar panel.

The control system 14 analyzes these signals through the analysis module to determine the illumination range of the light intensity, thereby determining the angle of the strongest light; Step 2: driving tracking, at this time, the control system 14 controls the electric telescopic rod 25 to retract, so that the locking mechanism releases the lock on the synchronous gear ring 23, and then controls the stepper motor to rotate through the motor control module, so that the photovoltaic bracket 3 and the light tracking sensor 35 are rotated and adjusted to achieve tracking of the light source; Step 3: Calibration and positioning, the rotation angle is detected in real time by the set potentiometer, and the actual rotation position angle is sent to the comparison processing module through the transceiver module. The comparison processing module compares and analyzes the actual rotation position angle of the photovoltaic bracket 3 and the light chasing sensor 35 with the angle calculated by the analysis module, so as to determine whether the rotation position of the photovoltaic bracket 3 is correct; if the actual rotation position angle deviates, the control system 14 controls the stepper motor to rotate through the motor control module, so that the photovoltaic bracket 3 and the light chasing sensor 35 rotate and adjust until the actual rotation position angle is the same as the angle calculated by the analysis module; Step 4: Protective locking. After the tracking is completed, the control system 14 controls the inner rod of the electric telescopic rod 25 to extend, so that the locking mechanism locks the synchronous gear ring 23, thereby locking the photovoltaic bracket 3; Step 5: Reset. When the light-chasing sensor 35 does not detect light for a long time, the light-chasing sensor 35 sends a signal to the analysis module. After analyzing the signal, the analysis module sends the information to the control system 14. The control system 14 sends a start signal to the motor control module. The motor control module controls the stepper motor to rotate back and reset, so that the photovoltaic bracket 3 and the light-chasing sensor 35 return to the initial position, that is, the photovoltaic bracket 3 and the light-chasing sensor 35 rotate to the east position.

[0036] Working principle: The light-chasing sensor 35 detects the strongest light angle in real time, so that the motor shaft of the stepper motor drives the main gear 24 to rotate, the main gear 24 drives the synchronous gear ring 23 to rotate, the synchronous gear ring 23 drives the light-chasing rotating seat 2 to rotate through the circular shaft 21, and the light-chasing rotating seat 2 drives the photovoltaic solar panel 31 and the light-chasing sensor 35 to rotate through the photovoltaic bracket 3, thereby adjusting the position of the photovoltaic solar panel 31 so that the strongest light can be vertically irradiated on the photovoltaic solar panel 31, thereby improving the efficiency of lighting; When the light-chasing rotating seat 2 needs to rotate, the inner rod of the electric telescopic rod 25 contracts to separate the locking tooth block 26 from the synchronous gear ring 23. When the photovoltaic solar panel 31 is adjusted, the inner rod of the electric telescopic rod 25 extends to engage the locking tooth block 26 with the synchronous gear ring 23, so that the locking mechanism locks the synchronous gear ring 23 and locks the light-chasing rotating seat 2 and the photovoltaic bracket 3 at the same time, so that the photovoltaic solar panel 31 can receive light.

[0037] The position of the photovoltaic solar panel 31 is adjusted by cooperating with the set light-chasing sensor 35 and the control system 14. The potentiometer, analysis and processing module, and comparison processing module in the control system 14 can detect in real time whether the actual rotation position of the photovoltaic solar panel 31 is correct, thereby ensuring that the strongest light can be irradiated on the photovoltaic solar panel 31 as vertically as possible, thereby improving the efficiency of lighting.

[0038] When there is severe weather such as strong winds, in order to prevent the photovoltaic solar panel 31 from being damaged by foreign objects, the output shaft of the servo motor drives a rotating shaft 32 to rotate, and the rotating shaft 32 drives two transmission belts 4 to rotate synchronously through two pulleys 33. The transmission belt 4 drives the protective component to rotate to the top of the photovoltaic solar panel 31, thereby protecting the photovoltaic solar panel 31.

[0039] When it is necessary to clean the dust and other debris on the upper end of the photovoltaic solar panel 31, the cleaning mechanism is driven to move along the upper end of the photovoltaic solar panel 31 by the movement of the conveyor belt 4, and the waterproof motor is started at the same time; The main shaft of the waterproof motor drives the rotating disk 72 to rotate, and the rotating disk 72 drives the transmission rod 73 to rotate. The transmission rod 73 slides up and down along the shaking groove 71. At the same time, the transmission rod 73 drives the shaking plate 7 to move back and forth left and right. The shaking plate 7 drives the cleaning brush 6 to move back and forth left and right along the upper end of the photovoltaic solar panel 31, thereby cleaning dust and other debris on the upper end of the photovoltaic solar panel 31. The cleaning brush 6 moves back and forth along the upper end of the photovoltaic solar panel 31, which improves the effect of cleaning dust and other debris on the upper end of the photovoltaic solar panel 31.

[0040] After cleaning is completed, the conveyor belt 4 rotates in the opposite direction, so that the cleaning mechanism moves back to the initial position. The initial position of the cleaning mechanism is set at one end of the photovoltaic bracket 3. At this time, the cleaning mechanism and the protective components will not block the photovoltaic solar panel 31.
