Description

Technical Field

[0001] This invention relates to the field of solar thermal collector technology, and more specifically, to an adjustable integrated photovoltaic power generation device and method. Background Technology

[0002] Solar photovoltaic (PV) panels are the core devices for realizing solar photovoltaic conversion. To improve the conversion efficiency, PV panels are usually installed at an adjustable angle on a support frame. By adjusting the tilt angle, they can effectively receive solar radiation. This is the basic layout widely used in PV support frames.

[0003] To further improve power generation efficiency, the industry has developed structures with tracking functions, such as semi-circular ring-type tracking adjustment brackets and circumferential rotating automatic tracking photovoltaic brackets. These brackets achieve circumferential rotation and angle adjustment through a rotating movable connection between the photovoltaic modules and the base, thereby matching the direction of solar irradiation in real time and significantly improving power generation efficiency under normal conditions.

[0004] However, when used in harsh environments with abundant sand and dust, such as the Gobi Desert, the rotating parts, gear meshing parts, and movable connection gaps of the aforementioned tracking bracket are prone to accumulating sand and dust. The intrusion and accumulation of sand and dust will significantly increase the resistance to movement, causing the adjustment action to become stuck, the tracking accuracy to decrease, and the response to be delayed. In severe cases, it may cause the drive mechanism to overload or completely fail. This not only hinders the normal operation of the tracking function and leads to power generation loss, but also greatly increases the maintenance frequency and failure risk of the equipment.

[0005] Therefore, this application proposes an adjustable integrated photovoltaic power generation device and method to solve the above problems. Summary of the Invention

[0006] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide an adjustable integrated photovoltaic power generation device and method, which solves the problems of low operational reliability, frequent maintenance and serious power generation loss caused by dust accumulation and jamming at the meshing parts of the rotating parts and gears of existing automatic tracking photovoltaic brackets in harsh sandy environments.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an adjustable integrated photovoltaic power generation device, including a base frame, a loading frame rotatably mounted on the top of the base frame, and a semi-ring toothed frame mounted on the bottom end of the loading frame. The loading frame is equipped with a solar collector plate, and the base frame contains a power component for driving the semi-ring toothed frame to rotate. The middle of the base frame allows the semi-ring toothed frame to slide through, and protective covers are installed on the front and rear sides of the base frame corresponding to the sliding path of the semi-ring toothed frame. A ring tooth cleaning assembly is provided on the lower side inside the protective cover, and an inner ring cleaning assembly is provided on the upper side inside the protective cover. The ring tooth cleaning assembly includes two vertically fixed partition plates on both sides inside the protective cover, which divide the inner cavity of the protective cover into a central tooth channel cavity and two dust collection cavities on both sides. An arc-shaped base plate is installed at the lower part of the tooth channel cavity, and a spring-loaded contact plate is slidably mounted on the arc-shaped base plate along the vertical direction. The upper part of the spring-loaded contact plate extends into the rack movement path of the semi-ring toothed frame.

[0008] In a new embodiment, the top of the spring abutment plate is fitted with a wear-resistant layer that abuts against the tooth profile of the semi-ring gear; when the semi-ring gear rotates, its tooth protrusions press against the top of the spring abutment plate, causing it to slide downwards, and when its tooth concave passes through, the spring abutment plate slides upwards to reset.

[0009] In a new embodiment, the ring tooth cleaning assembly further includes an air blowing assembly disposed within the tooth passage cavity. The air blowing assembly includes a compression airbag and a jet nozzle. The compression airbag is installed at the bottom of the tooth passage cavity, and the top of the compression airbag is connected to the bottom end of the spring contact plate. A one-way exhaust valve is installed on the compression airbag. A jet nozzle is installed at the lower part of one of the partition plates, and the jet nozzle is connected to the one-way exhaust valve through an internal pipeline. A dust discharge port is opened at the lower part of the other partition plate, and the opening direction of the dust discharge port corresponds to that of the jet nozzle. The opening height of both the jet nozzle and the dust discharge port is located above the curved substrate.

[0010] In a new embodiment, a one-way air intake valve is installed at the bottom of the compression airbag, the one-way air intake valve passing through the bottom of the protective cover and extending to the outside.

[0011] In a new embodiment, the inner ring cleaning assembly includes: a sliding groove symmetrically opened on the upper inner side of the two partition plates; a smooth plate slidably assembled in the sliding groove; an inclined scraper installed at the bottom end of the smooth plate, and its scraping surface is adapted to the inner ring wall of the semi-ring tooth frame; and an inclined dust groove correspondingly opened on the upper part of the partition plate and inclined.

[0012] In a new embodiment, a total dust inlet is provided at the bottom of both dust collection chambers, and the inner wall of each dust collection chamber is coated with a dust-repellent coating.

[0013] In a new embodiment, multiple mounting beams are installed laterally at intervals on the loading frame, and the solar collector is fixed to the mounting beams by pressure blocks or bolts.

[0014] In a new embodiment, the base frame is further provided with an assembly plate, and two sets of guide wheels are symmetrically and rotatably mounted on the bottom of the assembly plate. The rims of the guide wheels contact the inner ring wall of the semi-ring gear frame. The power component uses a drive motor and a gear meshing with the semi-ring gear frame to drive the semi-ring gear frame to rotate on the base frame.

[0015] A method for using an adjustable integrated photovoltaic power generation device includes the following steps: S1. Fix the base frame to the installation site, and assemble the solar collectors onto the loading frame through the installation beams. Connect the external power supply and control system to the drive motor. S2. Start the drive motor to drive the gear to rotate the semi-ring gear frame, which in turn drives the loading frame and the solar collector on it to rotate in order to track the sun's position and generate electricity by tracking the sun. S3. During the rotation of the semi-ring gear frame, the tooth convexity of its tooth profile periodically squeezes the spring contact plate, causing it to slide downward and compress the compression airbag. When the tooth concave passes through, the spring contact plate resets upward under the elastic reset action. The compression airbag recovers its deformation under its own elasticity and draws in air through the one-way air intake valve. When the compression airbag is compressed, the air inside it is ejected from the jet nozzle through the one-way exhaust valve and pipeline, blowing away the inter-tooth space of the semi-ring gear frame. The blown-off sand and dust enter the dust collection chamber through the dust discharge port. S4. During the rotation of the semi-ring tooth frame, the inclined scraper continuously contacts the inner ring wall of the semi-ring tooth frame, scraping off the sand and dust attached to it. The scraped-off sand and dust is guided into the dust collection chamber along the inclined dust groove. S5. The sand and dust collected in the dust collection chamber are guided by the dust-repellent coating on the inner wall and finally discharged to the outside through the main dust outlet.

[0016] Beneficial effects: Compared with the prior art, the advantages of the present invention are as follows: 1. The adjustable integrated photovoltaic power generation device integrates the ring tooth cleaning component and the inner ring cleaning component in an upper and lower partitioned layout within the protective cover. It targets the two easily jammed parts, the outer rack surface and the inner ring wall surface, and simultaneously performs pneumatic blowing and scraping while the device rotates to chase the light. This changes the passive dust accumulation situation of the traditional support, allowing the device to automatically remove sand and dust during operation. It effectively prevents transmission jamming, response delay and abnormal wear caused by sand and dust accumulation, and ensures the smoothness, accuracy and long-term reliability of the light chasing adjustment.

[0017] 2. By setting up an inner ring cleaning component, using a sliding groove, a smooth plate, and an inclined scraper, the blade of the inclined scraper can continuously adhere to the inner ring wall of the semi-ring toothed frame. The relative motion generated by the rotation of the equipment itself is converted into a beneficial cleaning action, which can continuously scrape off the attached sand and dust without additional power. In conjunction with the inclined dust groove, the scraped-off pollutants are quickly guided away from the working surface and collected in the dust collection chamber, solving the problem that large sliding surfaces are prone to accumulating dirt and increasing frictional resistance, and significantly reducing maintenance requirements.

[0018] 3. By setting up a ring tooth cleaning component and an air blowing component in conjunction, the spring contact plate is linked with the compression airbag. The mechanical compression potential energy of the tooth protrusion when the rack rotates is converted into the cleaning kinetic energy of the pulse airflow. Each compression of the tooth protrusion triggers a directional high-pressure blow that has just left the tooth gap. This provides a cleaning method that is strictly synchronized with the main body movement and is self-supplied with energy, solving the problem that sand and dust are easily trapped in the tooth gap and are difficult to clean.

[0019] 4. Through the dust collection chamber, dust-repellent coating and main dust outlet, it is seamlessly connected with the aforementioned cleaning action. The dust-repellent coating reduces the adhesion of sand and dust, allowing all the removed sand and dust to be smoothly collected under the action of gravity and discharged from the bottom. This ensures that the cleaned pollutants can be effectively discharged from the body rather than transferred internally, preventing secondary pollution and internal accumulation. It greatly reduces the reliance on frequent manual cleaning and maintenance, significantly improves the power generation efficiency and operational stability of photovoltaic power plants in dusty environments, and reduces the total life cycle operation and maintenance costs.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] This application provides an adjustable integrated photovoltaic power generation device and method, which solves the problems of low operational reliability, frequent maintenance, and severe power generation loss caused by dust accumulation and jamming at the meshing parts of the rotating parts and gears in harsh sandy environments. In use, by integrating the ring tooth cleaning component and the inner ring cleaning component in an upper and lower partitioned layout within the protective cover, pneumatic blowing and scraping are performed simultaneously on the two easily jammed parts, the outer rack surface and the inner ring wall surface, while the photovoltaic power generation device rotates to track the light, ensuring the smoothness and reliability of the light tracking adjustment.

[0033] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0034] Example 1, please refer to Figures 1-10This application provides an adjustable integrated photovoltaic power generation device, including a base frame 1, a loading frame 2 rotatably mounted on the top of the base frame 1, and a semi-ring toothed frame 3 mounted on the bottom of the loading frame 2. The loading frame 2 is provided with a solar collector plate 4, and the base frame 1 is provided with a power component that drives the semi-ring toothed frame 3 to rotate. The middle of the base frame 1 allows the semi-ring toothed frame 3 to slide through, and protective covers 5 are installed on the front and rear sides of the base frame 1 corresponding to the sliding path of the semi-ring toothed frame 3. A ring tooth cleaning assembly 6 is provided on the lower side of the inside of the protective cover 5, and an inner ring cleaning assembly 7 is provided on the upper side of the inside of the protective cover 5. The ring tooth cleaning assembly 6 includes two vertically fixed partition plates 61 on both sides of the inside of the protective cover 5. The two partition plates 61 divide the inner cavity of the protective cover 5 into a tooth channel cavity 62 in the middle and dust collection cavities 63 on both sides. An arc-shaped base plate 64 is installed at the lower part of the tooth channel cavity 62, and a spring abutment plate 65 is slidably installed on the arc-shaped base plate 64 in the vertical direction. The upper part of the spring abutment plate 65 extends into the rack movement path of the semi-ring toothed frame 3.

[0035] Furthermore, multiple mounting beams 21 are installed laterally at intervals on the loading frame 2, and the solar collector panel 4 is fixed to the mounting beams 21 by pressure blocks or bolts.

[0036] Furthermore, the base frame 1 is also equipped with an assembly plate 101. Two sets of guide wheels 102 are symmetrically rotated at the bottom of the assembly plate 101. The rim of the guide wheel 102 contacts the inner ring wall of the semi-ring gear 3. The power component uses a drive motor and a gear meshing with the semi-ring gear 3 to drive the semi-ring gear 3 to rotate on the base frame 1.

[0037] In the preferred embodiment of this solution, the ring tooth cleaning component 6 and the inner ring cleaning component 7 are integrated into an upper and lower partition layout within the protective cover 5. They target the two easily jammed parts, the outer rack surface and the inner ring wall surface, respectively. Pneumatic blowing and scraping are performed simultaneously with the rotation of the tracking light, so that the device can automatically remove sand and dust during operation. This effectively prevents transmission jamming, response delay and abnormal wear caused by sand and dust accumulation, and ensures the smoothness, accuracy and long-term reliability of the tracking light adjustment.

[0038] Specifically, the usage process of an adjustable integrated photovoltaic power generation device is as follows: First, the base frame 1 is securely installed in the predetermined position of the photovoltaic power station using anchor bolts and other means, and calibrated with a level to ensure its stable and level installation. Then, the solar collector panels 4 are horizontally fixed to the mounting beam 21 of the loading frame 2 with bolts, completing the mechanical assembly and electrical interconnection (series or parallel connection) of the photovoltaic panel array. Finally, the power supply lines and control signal lines of the drive motor inside the device are connected to the power distribution cabinet and central control system of the power station, respectively, to complete the integration of the power and control circuits and ensure smooth power supply and command communication. Second, the central control system calculates the required azimuth and tilt angles of the photovoltaic array based on a preset solar trajectory algorithm or real-time signals from photoelectric sensors, and generates a rotation command. The control system then starts the drive motor, and the motor output shaft drives the drive gear to rotate. The drive gear meshes with the arc-shaped rack of the semi-ring gear 3 fixed at the bottom of the loading frame 2, causing the semi-ring gear 3 to rotate along its arc-shaped track. During this rotation, multiple guide wheels 102 installed at the bottom of the mounting plate 101 inside the base frame 1 provide rolling support and limit for the inner ring wall of the semi-ring gear 3, ensuring that its rotation is smooth and accurate. The rotation of the semi-ring gear 3 directly drives the entire loading frame 2, which is rigidly connected to it, and all the solar collectors 4 on it to adjust synchronously to the target angle, so that the sunlight shines vertically or nearly vertically on the panel surface, thereby putting the system into a high-efficiency power generation state. Third, this process is synchronized and automatic with the rotation of the tracking light. When the semi-ring gear 3 rotates, the teeth on its rack, as they pass through the toothed cavity 62 inside the protective cover 5, will press down on the top of the spring contact plate 65. The spring contact plate 65 is pressed down and slides downward along the arc-shaped base plate 64. This action directly and synchronously compresses the compression airbag 81 fixed to its bottom. The air pressure inside the compression airbag 81 increases accordingly. When the pressure overcomes the opening resistance of the one-way exhaust valve 811, the valve opens, and a pulse of air flows through. Through the pipeline, the jet nozzle 82 installed on the side partition plate 61 sprays out at high speed, instantly blowing away the gap between the teeth that just passed in front of the jet nozzle 82, dispersing the accumulated sand and dust. The sand and dust blown away from the teeth are discharged laterally from the dust outlet 83 opposite the jet nozzle 82 under the guidance of the airflow and fall into the dust collection chamber 63 below. The relative arrangement of the jet nozzle 82 and the dust outlet 83 forms a linear airflow channel that runs through the tooth passage cavity 62, ensuring the blowing efficiency and preventing the sand and dust from settling again in the cavity. Subsequently, when the toothed part on the rack rotates to the spring contact plate 65, the compression is released, and the spring contact plate 65 rebounds upward under the action of its own return spring. At the same time, the compressed air bladder 81 returns to its original shape by its own elasticity, and negative pressure is generated inside, which draws in clean air from the outside through the one-way air inlet valve 812 at the bottom, thus reserving air source for the next purging. It should be noted that, since the tracking light adjustment is slow and uniform, the compression and rebound action of the spring contact plate 65 is low in frequency and stable in stroke, within a reasonable range of mechanical movement, avoiding problems that may be caused by high-speed continuous impact, ensuring that the compression airbag 81 has sufficient time to complete the effective compression and suction stroke, thereby generating a pulsed airflow with sufficient pressure, ensuring the reliability of the blowing and cleaning. Fourth, during the rotation of the tracking light, the inner ring wall of the semi-ring tooth frame 3 always maintains contact with the scraping edge of the inclined scraper 73. The inclined scraper 73 is constrained in the sliding groove 71 of the partition plate 61 by the smooth plate 72. This structure enables it to maintain a stable scraping posture. The sand and dust attached to the inner ring wall are continuously scraped off. The scraped sand and dust are smoothly guided into the dust collection chamber 63 along the inclined surface of the inclined scraper 73 and the inclined bottom surface of the inclined dust groove 74 connected to it on the upper part of the partition plate 61. At this point, the sand and dust from the toothed surface blowing and the inner ring surface scraping are all collected in the dust collection chamber 63. The dust-repellent coating on the inner wall of the dust collection chamber 63 can effectively reduce the adhesion of sand and dust, making it easy to slide to the bottom of the chamber under the action of gravity. The accumulated sand and dust are automatically discharged to the outside of the device through the total dust outlet 631 at the bottom by gravity or slight vibration. In areas where sandstorms occur frequently, a hose can be connected at the total dust outlet 631 to guide the sand and dust to a fixed collection point. Fifth, to ensure the long-term reliable operation of the device in harsh sand and dust environments, a regular maintenance plan should be formulated and implemented. For example, it is recommended to conduct the following checks every quarter or after experiencing strong sand and dust weather: Open the inspection port of the protective cover 5 to visually inspect and assess the wear of the wear-resistant layer at the top of the spring contact plate 65. If the wear exceeds the limit, it should be replaced; check whether the flow channels such as the air nozzle 82, dust outlet 83 and inclined dust trough 74 are blocked to ensure that the cleaning path is unobstructed; check the wear condition of the guide wheel 102 rim and whether the rotation is flexible. If necessary, clean, lubricate or replace it to ensure that the semi-ring gear 3 always runs smoothly and with minimal resistance.

[0039] In this embodiment, please refer to Figure 9 As shown, the top of the spring contact plate 65 is fitted with a wear-resistant layer that abuts against the tooth profile of the semi-ring gear 3; when the semi-ring gear 3 rotates, its tooth protrusions press against the top of the spring contact plate 65, causing it to slide downwards, and when its tooth concave passes through, the spring contact plate 65 slides upwards to reset.

[0040] In a preferred embodiment of this solution, a wear-resistant layer is provided at the top of the spring contact plate 65. This wear-resistant layer maintains contact with the tooth profile of the semi-ring gear 3. When the semi-ring gear 3 rotates, its tooth protrusions squeeze the wear-resistant layer, driving the entire spring contact plate 65 to slide downwards along the arc-shaped substrate 64. When the tooth concave part rotates into position, the squeezing effect disappears, and the spring contact plate 65 slides upwards under the push of the return spring, returning to its initial position. As a direct contact and friction interface, the wear-resistant layer withstands the periodic mechanical impact and sliding friction caused by the rotation of the rack, thereby protecting the base material of the spring contact plate 65. This wear-resistant layer solves the problem that the top of the spring contact plate 65 is prone to wear or scratches due to long-term and repeated contact with the hard tooth profile. It helps to maintain the initial stroke and return position of the spring contact plate 65, so that the squeezing and return actions driven by it can remain stable over a long operating cycle, thereby supporting the continuous and reliable operation of the subsequent air blowing assembly 8.

[0041] In this embodiment, please refer to Figures 5-10 As shown, the ring tooth cleaning assembly 6 also includes an air blowing assembly 8 disposed in the tooth passage cavity 62. The air blowing assembly 8 includes a compression airbag 81 and a jet nozzle 82. The compression airbag 81 is installed at the bottom of the tooth passage cavity 62, and the top of the compression airbag 81 is connected to the bottom end of the spring contact plate 65. A one-way exhaust valve 811 is installed on the compression airbag 81. A jet nozzle 82 is installed at the lower part of one of the partition plates 61. The jet nozzle 82 is connected to the one-way exhaust valve 811 through an internal pipeline. A dust discharge port 83 is opened at the lower part of the other partition plate 61. The opening direction of the dust discharge port 83 corresponds to that of the jet nozzle 82. The opening height of the jet nozzle 82 and the dust discharge port 83 are both located above the curved base plate 64.

[0042] Furthermore, in this embodiment, a total dust inlet 631 is provided at the bottom of both dust collection chambers 63, and the inner wall of the dust collection chamber 63 is coated with a dust-repellent coating.

[0043] In a preferred embodiment of this solution, the compression airbag 81 is directly connected to the bottom of the spring contact plate 65, so that the downward mechanical movement of the spring contact plate 65 driven by the toothed protrusion is simultaneously converted into compression of the compression airbag 81. After the compression airbag 81 is compressed, the internal air is concentratedly ejected from the jet nozzle 82 through the one-way exhaust valve 811 and the pipeline. This airflow blows the gap of the rack that it has just passed through in a directional manner, solving the problem that the tracking bracket is prone to accumulating and embedding sand and dust in the gap of the rack of the semi-ring rack 3, which leads to drive jamming or accelerated wear. Since the cleaning power comes entirely from the mechanical motion necessary for the rotation of the tracking beam itself, no additional motor or air pump is required, achieving real-time cleaning with zero additional energy consumption. Simultaneously, the blowing action is strictly synchronized with the rack and pinion movement; each time the tooth protrusion squeezes, the gap it just left is blew out, ensuring timely and targeted cleaning. The air nozzle 82 and dust outlet 83 are positioned opposite each other, forming a through-flow airflow within the toothed cavity 62. This effectively carries sand and dust out and discharges it into the dust collection chamber 63, reducing secondary settling of sand and dust in key transmission parts. This effectively lowers the risk of the transmission system jamming due to sand and dust accumulation, ensuring the continuity and accuracy of the tracking beam adjustment function. Secondly, the dust-repellent coating reduces the surface energy of the inner wall of the dust collection chamber 63, making it difficult for sand and dust particles to adhere. The accumulated sand and dust slides down the inner wall to the bottom of the chamber under the action of gravity. The total dust outlet 631 at the bottom of the chamber provides a channel for the concentrated discharge of sand and dust, solving the problem that the cleaned-up sand and dust are easy to remain, accumulate, or even harden in the dust collection chamber 63.

[0044] In this embodiment, please refer to Figures 7-9 As shown, a one-way air intake valve 812 is installed at the bottom of the compression airbag 81. The one-way air intake valve 812 passes through the bottom of the protective cover 5 and extends to the outside.

[0045] In the preferred embodiment of this solution, when the spring contact plate 65 drives the compression airbag 81 to complete the exhaust and return to its original position, a negative pressure is generated inside the airbag (the pressure is lower than the external environment). At this time, the pressure of the external air pushes open the valve plate of the one-way air intake valve 812, allowing external air to enter the compression airbag 81 until the internal and external pressures are balanced. The compression airbag 81 then returns to its original state, ensuring that after completing one compression exhaust, the compression airbag 81 can quickly and fully draw in air and return to its original position, thus reserving a sufficient air source for the next compression jet cycle and maintaining a continuous and stable purging capability.

[0046] In this embodiment, please refer to Figures 5-8 As shown, the inner ring cleaning assembly 7 includes: a slide groove 71, symmetrically opened on the upper inner side of the two partition plates 61; a smooth plate 72, slidably assembled in the slide groove 71; an inclined scraper 73, installed at the bottom end of the smooth plate 72, and its scraping surface is adapted to the inner ring wall surface of the semi-ring tooth frame 3; and an inclined dust groove 74, correspondingly opened on the upper part of the partition plate 61 and inclined.

[0047] In a preferred embodiment of this solution, the inclined scraper 73 is slidably mounted in the slide groove 71 of the partition plate 61 via the smooth plate 72, so that its scraping surface can always be in contact with the inner ring wall of the semi-ring tooth frame 3. When the semi-ring tooth frame 3 rotates, its inner ring wall and the stationary inclined scraper 73 move relative to each other, and the sand and dust attached to the wall are continuously scraped off. The scraped sand and dust slide down the inclined surface of the inclined scraper 73 and fall into the inclined dust groove 74 connected to it, which is inclined in shape, and is finally guided into the dust collection chamber 63 for discharge, thus solving the problem that sand and dust are easily attached and accumulated on the inner ring wall of the semi-ring tooth frame 3 in a sandy environment. Meanwhile, by utilizing the rotation of the semi-ring toothed frame 3 itself, the inner ring wall surface is mechanically scraped continuously in all directions without the need for an additional drive device, thus achieving routine cleaning of key sliding surfaces. The scraped-off sand and dust are quickly guided away from the cleaning area through the inclined structure of the inclined dust groove 74 and enter the dust collection chamber 63 for centralized processing, preventing the scraped-off sand and dust from falling back into the rotating pair or accumulating in the chamber.

[0048] Example 2, please refer to Figures 1-10 This application also provides a method for using an adjustable integrated photovoltaic power generation device, including the following steps: S1. Fix the base frame 1 to the installation site, and assemble the solar collector 4 onto the loading frame 2 via the installation beam 21. Connect the external power supply and control system to the drive motor. S2. Start the drive motor to drive the drive gear to rotate the semi-ring gear 3, which in turn drives the loading frame 2 and the solar collector 4 on it to rotate, so as to track the sun's position and generate electricity by tracking the sun. S3. During the rotation of the semi-ring gear 3, the tooth protrusions of its tooth profile periodically press the spring contact plate 65, causing it to slide downwards and compress the compression airbag 81. When the tooth concave passes through, the spring contact plate 65 resets upwards under the elastic reset action. The compression airbag 81 recovers its deformation under its own elasticity and draws in air through the one-way air intake valve 812. When the compression airbag 81 is compressed, the air inside it is ejected from the jet nozzle 82 through the one-way exhaust valve 811 and pipeline, blowing away the gaps between the teeth of the semi-ring gear 3. The blown-off sand and dust enter the dust collection chamber 63 through the dust discharge port 83. S4. During the rotation of the semi-ring tooth frame 3, the inclined scraper 73 continuously contacts the inner ring wall of the semi-ring tooth frame 3 to scrape off the sand and dust attached to it. The scraped-off sand and dust is guided into the dust collection chamber 63 along the inclined dust groove 74. S5. The sand and dust collected in the dust collection chamber 63 are guided by the dust-repellent coating on the inner wall and finally discharged to the outside through the main dust outlet 631.

9. A method of using an adjustable integrated photovoltaic power generation device, characterized in that, The adjustable integrated photovoltaic power generation device according to any one of claims 1-8 includes the following steps: S1. Fix the base frame (1) to the installation site, and assemble the solar collector (4) onto the loading frame (2) through the installation beam (21), and connect the external power supply and control system to the drive motor; S2. Start the drive motor to drive the drive gear to drive the semi-ring gear frame (3) to rotate, and then drive the loading frame (2) and the solar collector plate (4) on it to rotate, so as to track the sun's position and generate electricity by chasing the sun; S3. During the rotation of the semi-ring gear frame (3), the tooth convexity of its tooth profile periodically squeezes the spring contact plate (65), causing it to slide downward and compress the compression airbag (81). When the tooth concave passes through, the spring contact plate (65) resets upward under the elastic reset action. The compression airbag (81) recovers its deformation under its own elasticity and draws in air through the one-way air intake valve (812). When the compression airbag (81) is compressed, the air inside it is ejected from the jet nozzle (82) through the one-way exhaust valve (811) and pipeline, blowing the inter-tooth space of the semi-ring gear frame (3).

During the rotation of the semi-ring tooth frame (3), the inclined scraper (73) continuously contacts the inner ring wall of the semi-ring tooth frame (3) to scrape off the sand and dust attached to it. The scraped-off sand and dust is introduced into the dust collection chamber (63) along the inclined dust groove (74). S5. The sand and dust collected in the dust collection chamber (63) are guided by the dust-repellent coating on the inner wall and finally discharged to the outside through the main dust outlet (631).
