[0002] Distributed photovoltaic power generation is a way of generating electricity based on solar energy. It refers to the use of solar energy to convert light energy into electrical energy through photovoltaic modules in various places such as buildings, parking lots, industrial areas, etc., and use it to provide building electricity for the place or directly output it to the municipal power system.

[0003] Compared with traditional solar power generation systems, distributed photovoltaic power generation is more flexible and more adaptable.

Figure 1 As shown, traditional distributed photovoltaic power generation devices usually use support columns as the supporting foundation and the top is connected to the structure of solar photovoltaic panels. Such a structure is relatively simple, and the installation of distributed photovoltaic power generation panel components is more troublesome. The support columns cannot be raised or lowered, and the photovoltaic panel components need to be hoisted when installed, which is time-consuming and labor-intensive, and there are also major safety hazards. At the same time, the distributed photovoltaic power generation device of the prior art has a single structure. In different use sites and environments, the size of the photovoltaic panels varies in specifications and models, and the installation inclination angles are also different.

[0028] Example 1: Figures 2 to 5 As shown:

[0029] A clean column-type distributed photovoltaic power generation assembly, the photovoltaic power generation assembly comprises a lifting structure 1, a panel structure 2 and a cleaning structure 3. Figure 2 As shown: the lifting structure includes a base plate 11, a first column 12, a hydraulic lifting column 13 and a second column 14. The base plate 11 is horizontally distributed, and the first column 12 is vertically distributed and arranged on the base plate 11; holes are opened on the base plate for connecting and installing pre-buried anchor bolts. Figure 4 As shown: the hydraulic lifting column 13 is arranged in the first column 12 and connected to the second column 14; the hydraulic lifting column is connected to a control button, which is arranged on the first column. The lifting and lowering movement of the hydraulic lifting column brings about the lifting and lowering operation of the second column, thereby driving the lifting and lowering operation of the electric board structure. The first column 12 and the bottom plate 11 are fixed by welding, and a reinforcing rib 15 is also provided between the two; such a setting is used to enhance the stability of the connection. The second column 14 is connected to the base 21 by a sleeve 16, and the sleeve 16 is integrally formed with the base 21 and is connected to the second column 14 by threads; the purpose of such a setting is to adopt a split structure design, which is easy to carry to the construction site and complete quick assembly. A reinforcing rib 15 is also provided between the sleeve 16 and the base 21, and such a setting is used to enhance the supporting stability of the base. The photovoltaic power generation component has a reasonable structural design. The cooperation of the first column, the hydraulic lifting column and the second column is used to lower the height during the installation stage, so that workers can install it conveniently without the need for lifting equipment, making the installation more efficient. At the same time, reinforcing ribs are used to enhance the stability of the power generation component.

The base 21 is horizontally distributed and is connected and fixed to the second column 14. The staff can install the panel structure and then complete the fixed installation through the rotation connection between the sleeve and the second column. This operation saves time and effort. The mounting frame 22 is a concave structure as a whole, and includes a connecting arm 221 and a beam 222 arranged between the two connecting arms 221; the two connecting arms 221 and the base 21 are kept in rotation connection by a rotating shaft. In this way, from a side view, the base, the mounting frame and the photovoltaic panel are distributed in a triangular shape. The photovoltaic panel 23 is fixedly installed between the base 21 and the beam 222 by bolts. The telescopic connecting rod 24 is telescopic, and one end is arranged on the base 21, and the other end is connected to the connecting arm 221, so that the photovoltaic panel 23 is installed at a preset tilt angle. As shown Figure 3As shown: Specifically, the telescopic connecting rod 24 adopts an electric hydraulic push rod, and the two ends of the electric hydraulic push rod are respectively hinged with the connecting arm 221 and the base 21. The electric hydraulic push rod is connected with a control button, which is also set on the first column for easy operation. A card slot 25 is also provided on the base 21 for connecting and installing the photovoltaic panel 23 and providing a strong foundation for subsequent cleaning. Further, the base, the mounting frame, the photovoltaic panel and the telescopic connecting rod are coordinated, and the telescopic connecting rod can be retracted to adjust the angle between the connecting arm and the base, and then the size of the photovoltaic panel between the cross beam and the base can be adjusted to adapt to the installation of photovoltaic panels of different specifications and models, and at the same time complete the installation of photovoltaic panels at a preset angle, which is more practical.

[0031] like Figure 1 As shown in the figure: In this embodiment, the cleaning structure 3 is arranged on the base 21, and includes a rotating shaft 31, a cleaning rod 32, a cleaning brush 33, and a driving member 34. The rotating shaft 31 is arranged on the base 21, specifically, in the middle of the base and close to the photovoltaic panel. One end of the cleaning rod 32 is sleeved and installed on the rotating shaft 31 to drive the cleaning rod to rotate. Figure 5 As shown: the cleaning brushes 33 are evenly distributed on the cleaning rod 32; they are used to clean the surface of the photovoltaic panel. The driving member 34 is used to drive the cleaning rod 32 and the cleaning brush 33 to complete a 180-degree cleaning operation. Specifically, refer to Figure 5 The structure shown is as follows: the driving member 34 includes a driving motor 341, a driving wheel 342 and a driven wheel 343. The driving motor 341 is arranged on the base 21, wherein the driving motor adopts a servo control motor, which is used to control the driving motor to swing back and forth within the range of 180 degrees of the rotation angle. This embodiment is used for auxiliary control, and a stop can be set on the base and on both sides of the rotating shaft to limit the cleaning rod. The driving wheel 342 is arranged on the output shaft of the driving motor 341. The driven wheel 343 is arranged on the rotating shaft 31, and the driving wheel 342 and the driven wheel 343 are meshed for transmission. The driving motor is also connected to a control button, which is arranged on the control panel of the first column. Among them, the electricity required for this embodiment is provided by a battery to provide electric drive, and the battery is arranged in the first column and can be connected to a photovoltaic panel to provide energy storage.

[0032] In the initial state, the drive motor does not work, the cleaning rod is at the connection between the base and the photovoltaic panel, and the cleaning rod is set to be long enough. The drive motor rotates forward, driving the active wheel to rotate, and then driving the driven wheel and the cleaning rod to rotate, and the cleaning brush begins to complete the 180-degree rotation cleaning operation. The drive motor reverses and starts to drive the cleaning rod and the cleaning brush to reset, completing another cleaning operation in the process. Further, by using the coordination of the rotating shaft, the cleaning rod, the cleaning brush, and the driving member, the drive motor can be started by connecting the control switch, thereby driving the cleaning rod to swing back and forth within a range of 180 degrees, completing the preliminary cleaning of the dust on the surface of the photovoltaic panel by the cleaning brush; further ensuring the cleanliness of the photovoltaic panel surface, that is, ensuring the efficiency of photovoltaic power generation.

[0033] Based on the technical solution of Example 1, a clean column-type distributed photovoltaic power generation assembly also includes: Figure 6 As shown: the cleaning rod 32 is also provided with an air pump 41, which is a micro air pump and is fixed to the cleaning rod by bolts. The air pump 41 is connected to a control switch 42, which is set on the first column and is set at a low position for easy control by personnel. The cleaning rod is provided with an air chamber 43, and the bottom end of the air chamber 43 is provided with a plurality of air jet holes 44, such as Figure 7 As shown: the array-type jet holes are located on one side of the cleaning brush. After the cleaning brush completes a cleaning, there will be residual dust on the surface of the photovoltaic panel. At this time, the air pump starts to inflate the air chamber, and then disperses it evenly into the jet holes. During the swinging cleaning process of the cleaning brush, the blowing operation is completed, which further enhances the cleaning effect of the photovoltaic panel and ensures the efficiency of photovoltaic power generation.

[0034] On the basis of the technical solution of Example 1, a clean column-type distributed photovoltaic power generation assembly also includes: a purification chamber 51 is provided in the cleaning rod 32, and a through exhaust hole 52 is provided at the bottom of the purification chamber 51; the exhaust holes are evenly distributed. An air filter cotton 53 is provided in the purification chamber 51 for absorbing dust and filtering airflow. A fan 54 is provided on the cleaning rod 32 through a bracket, and the fan is connected to a control button. The input end of the fan 54 is connected to the purification chamber 51, and the fan adopts a suction fan. In this way, when the cleaning brush completes a cleaning, there will be residual dust on the surface of the photovoltaic panel. At this time, the fan starts and starts to suck air into the purification chamber through the uniform exhaust holes. In the process of the cleaning brush swinging and cleaning, the absorption and filtering operation of the residual dust is completed. Compared with the cleaning method of Example 2, this method is more practical and does not leave dust. The cleaning effect of the photovoltaic panel is further enhanced, and the efficiency of photovoltaic power generation is guaranteed.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
