[0032] See also Figure 6-7 The locking assembly 116 in this embodiment includes a connecting block 1161 that is fixedly connected to the middle of the side plates 111 on both sides to realize pre-assembled positioning connection cooperation, a clamping block 1162 that is symmetrically fixedly connected to the left and right sides of the photovoltaic frame 8 and combined with the connecting block 1161, a screw 1163 that is vertically rotatably connected to the inside of the clamping block 1162, a pressure shell 1164 that is threadedly connected to the lower end of the screw 1163, a connecting arm 1165 that is symmetrically rotatably connected to the left and right sides of the inside of the pressure shell 1164 for synchronous relative or opposite push-pull transmission cooperation, a locking block 1166 that is correspondingly installed at the lower end of the connecting arm 1165 on both sides to realize outward movement, plug-in and locking cooperation, a guide rod 1167 that is laterally inserted between the locking blocks 1166 on both sides for support and mobile guiding cooperation, and a compression spring 1168 that is symmetrically arranged on the left and right sides of the outer ends of the guide rods 1167 on both sides for elastic pullback cooperation, and the outer end of the locking block 1166 is clamped with the inside of the clamping block 1162.

[0035] Further explanation: the middle part of the fixed block 1172 is opened in a rectangular hollow shape as a whole, and the fixed block 1172 is slidably connected to the left and right sides of the scraper strip 1171 through the internal rectangular hollow part, ensuring that the scraper strip 1171 can be efficiently installed and connected through the fixed blocks 1172 arranged on both sides; the first spring 1175 and the second spring 1176 are arranged corresponding to the lower end and the upper end along the adjusting rod 1173, and the upper end of the first spring 1175 and the lower end of the second spring 1176 are respectively abutted against the upper and lower end surfaces on the right side of the scraper strip 1171, ensuring that the first spring 1175 and the second spring 1176 cooperate to flexibly adjust the abutment and compression state of the scraper strip 1171.

[0036] Here’s how it works:

[0037] When the photovoltaic power generation device is to be used, the bracket 1 can be used to achieve stable support for the photovoltaic frame 8 as a whole, so that the photovoltaic panel 9 installed inside the upper end of the photovoltaic frame 8 can be in a stable state to perform light-induced power generation. The photosensitive sensors 10 arranged on the left and right sides of the upper end of the photovoltaic frame 8 will monitor the external light intensity in real time, and transmit the monitored data to the controller 4 arranged on the right side of the photocell 3 to perform a set threshold comparison activity. However, when it is lower than the set threshold, the controller 4 will cooperate with the photocell 3 to send a control signal to operate the motor 5 arranged on the right side of the upper end of the bracket 1. In this way, the rotating shaft 6 connected to the left side of the motor 5 will drive the connecting frame 7 to rotate, so that the photovoltaic frame 8 installed on the top of the connecting frame 7 can adjust its state, so that the photovoltaic panel 9 can efficiently and flexibly adjust the use angle to match the external light angle and perform efficient light-induced power generation activities.

[0038] In order to ensure that the photovoltaic panel 9 is in the external environment for a long time and is not easy to adhere to dust on the outside when performing light-generating activities, thereby reducing the power generation efficiency, a covering dust-proof device 11 is provided on the outside of the photovoltaic frame 8, that is, a covering film 115 covers the outside of the photovoltaic frame 8 to assist in covering the entire photovoltaic panel 9. At the same time, the front and rear sides of the covering film 115 will be connected to the first rotating shaft 113 and the second rotating shaft 114 respectively provided between the front and rear of the side panels 111 on both sides, so that the installation and use of the covering film 115 can be completed. In this way, the covering film 115 in a transparent film state can effectively block external dust and prevent dust from directly adhering to the outside. To the outside of the photovoltaic panel 9, the overall power generation efficiency of the photovoltaic panel 9 is reduced, and the transparency of the covering film 115 will be reduced after a period of use. In order to ensure transparency and stabilize the overall power generation efficiency of the photovoltaic panel 9, the servo motor 112 provided at the front end of the right side panel 111 can be operated to enable the servo motor 112 to realize the rotation of the first rotating shaft 113, and the covering film 115 can be driven to change the upper and lower positions of the covering film 115, so that the part with higher transparency on the bottom surface is rotated and adjusted to the upper end to carry out dust-proof covering and efficient light-transmitting power generation, thereby achieving the advantages of dust-proof covering of the photovoltaic panel 9 and auxiliary adjustment of the covering state;

[0039] In order to adjust the partial covering film 115 to a blurred bottom surface, the covering film 115 can still be used for efficient covering and dust prevention. A scraping assembly 117 is provided at the bottom of the front end of the side plates 111 on both sides, so that when the covering film 115 is adjusted, it can contact with the scraping strip 1171 provided inside the scraping assembly 117, so that the scraping strip 1171 assists in scraping and cleaning the dust attached to the outside, so that the partial covering film 115 is restored to a transparent state. At the same time, the adjusting rod 1173 provided inside the fixed block 1172 is rotated, and the movable sleeve 1174 connected with the outside by threading can be moved upward. As the movable sleeve 1174 moves upward, the upper end of the top is moved upward. The first spring 1175 is offset against each other, so that the first spring 1175 can push up the scraping strip 1171 to compress the second spring 1176 connected to the upper ends of the left and right sides of the scraping strip 1171, so that, in combination with the elastic force effect of the first spring 1175 and the second spring 1176, the scraping strip 1171 and the lower end of the front side of the covering film 115 can be stably and efficiently offset to improve the scraping and dust removal effect, and in combination with the elastic force of the first spring 1175 and the second spring 1176, the scraping strip 1171 can also be quickly pushed down and reset automatically, thereby achieving the advantages of auxiliary scraping and dust removal on the outer side of the covering film 115 and improving the utilization rate of the covering film 115;

[0040] If it is necessary to disassemble the covering dustproof device 111, the screw 1163 of the locking assembly 116 provided in the middle of the side panel 111 can be rotated. As the screw 1163 rotates, the compression shell 1164 threadedly connected to the bottom can be moved upward. As the compression shell 1164 moves upward, the downward pressure effect of the connecting arms 1165 provided on both sides of the interior will be released. In this way, the compression spring 1168 installed on both sides of the outer end of the guide rod 1167 and in a stretched state will pull back the locking block 1166 connected to the corresponding outside, so that the locking block 1166 moves out of the opening opened on the left or right side of the card block 1162 to unlock the device. In this way, the connection between the side panel 111 and the left and right sides of the photovoltaic frame 8 can be released, so that the side panel 111 as a whole can be quickly disassembled to complete the overall rapid disassembly of the covering dustproof device 11, thereby achieving the advantages of rapid disassembly of the covering dustproof device 11 as a whole and improving the convenience of use.

[0041] The utility model provides an inclined single-axis tracking photovoltaic power generation device, which is provided with a covering dust prevention device 11, which is driven by a first rotating shaft 113 and a second rotating shaft 114, so that a covering film 115 can be driven to perform adjustable covering and dust prevention on the outer side of the photovoltaic panel 9, thereby achieving the advantages of covering and dust prevention of the photovoltaic panel 9 and auxiliary adjustment of the covering state, and a locking component 116 is provided, which cooperates with the transmission of a screw rod 1163 and a compression shell 1164 and the pullback of a compression spring 1168 to quickly release the lock block 1166 and the card block 1162 to conveniently disassemble the covering and dust prevention device 11, thereby achieving the advantages of rapid overall disassembly of the covering and dust prevention device 11 and improving the convenience of use, and a scraping component 117 is provided, which is scraped by a scraping strip 1171 to perform auxiliary scraping and cleaning on the outer side of the covering film 115, and at the same time, cooperates with the first spring 1175 and the second spring 1176 to improve the cleaning effect of the scraping strip 1171, thereby achieving the advantages of auxiliary scraping and dust removal on the outer side of the covering film 115 and improving the utilization rate of the covering film 115.
