[0002] Distributed photovoltaic power generation is a system that uses solar energy to generate electricity. It converts solar radiation into electrical energy through photovoltaic modules and supplies the electrical energy directly to users without passing through traditional large-scale power centers. This power generation method is mainly based on self-generation and self-use on the user side, and the excess electricity is connected to the grid, and the distribution network system is balanced and regulated. Distributed photovoltaic power generation systems are usually installed in locations near users, such as building roofs, facades, public facilities or ground brackets.

However, the distributed photovoltaic power generation device of the prior art has a simple structure and is relatively troublesome to install. The installation of the support column requires sufficient strength of the supporting foundation, requires more concrete casting surface, and has a high installation cost. At the same time, the installation of distributed photovoltaic power generation components is relatively troublesome. The support column cannot be raised or lowered. When installing the photovoltaic panel components, hoisting is required, which is time-consuming and labor-intensive, and there are major safety hazards.

In different use sites and environments, the size of the photovoltaic panels has different specifications and models, and the installation inclination angle is also different.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0022] Example 1: Figures 2 to 4 As shown:

[0023] A new type of distributed photovoltaic power generation equipment includes a support member 1, a lifting member 2 and a photovoltaic assembly 3. The support member 1 includes a base 4, a pulley 5 and a support leg 6. The base 4 is horizontally distributed, and the base can be set to have a sufficient thickness and an internal space for accommodating the assembly structure of the photovoltaic power generation equipment. The pulley 5 is set on the base 4 through a bracket, and the bracket can be fixed to the base by bolt connection, so that it can be detached for use. When the base is fixed, the pulley is disassembled and used in the next group of photovoltaic power generation equipment to reduce manufacturing costs. The support leg 6 is retractable to make the base 4 movable and fixable. Specifically, if Figure 2 As shown: the support leg 6 includes a hydraulic telescopic rod 13 and an angle plate 14. The hydraulic telescopic rod 13 is vertically distributed on the base 4, and the hydraulic telescopic rod is connected to a control switch, which is installed on the side wall of the base for easy operation by the staff.

In the fixed state, the staff can use long rivets to penetrate the angle plate for installation to ensure the stability of the foundation of the photovoltaic power generation equipment.

[0024] like Figure 3As shown: wherein the base 4 is divided into a fixed state and a mobile state. Wherein, when the base 4 is in the fixed state, the hydraulic telescopic rod 13 is extended, the pulley 5 is off the ground, and the pulley is detachable. When the base 4 is in the mobile state, the hydraulic telescopic rod 13 is contracted, and the overall height of the support leg 6 is less than the setting height of the pulley 5, which is convenient for carrying the photovoltaic power generation components based on the structure of the pulley to achieve convenient movement, saving time and effort. The distributed photovoltaic power generation equipment has a reasonable structural design, and adopts the cooperation of pulleys and support legs to realize the convenient movement of the support foundation of the equipment, which is convenient for the staff to carry to the construction site, saving time and effort; at the same time, the support legs are extended, the pulley is off the ground, and the angle plate can be fixedly connected to the ground by rivets, with low manufacturing cost and high cost performance.

The hydraulic lifting column 16 is arranged in the first column 15, and the top end is connected to the second column 17. The hydraulic lifting column is also connected to a control button, which is convenient for the staff to start and control. The lifting and lowering movement of the hydraulic lifting column drives the first column to rise and fall. In the initial state, the hydraulic lifting column is in a retracted state, and the staff can conveniently install the photovoltaic components. The second column 17 is connected to the support plate 7 by a sleeve 19, and the sleeve 19 is integrally formed with the support plate 7 and is connected to the second column 17 by a thread; the purpose of such a setting is to facilitate the efficient installation of each component at the construction site through the design of a split structure. A reinforcing rib 18 is also provided between the sleeve 19 and the support plate 7 to enhance stability. By utilizing the cooperation of the first column, the hydraulic lifting column and the second column, the height is lowered during the installation phase, allowing workers to conveniently install without the need for lifting equipment, making the installation more efficient.

The support plate 7 is horizontally distributed, and the auxiliary frame 8 is a concave structure as a whole, and includes a connecting arm 11 and a crossbeam 12 arranged between the two connecting arms 11. The two connecting arms 11 are rotatably connected to the support plate 7 through a rotating shaft, and the photovoltaic panel 9 is fixedly installed between the support plate 7 and the auxiliary frame 8 by bolts. In the installed state, the photovoltaic panel, the support plate and the auxiliary frame are distributed in a triangular shape from a side view. The telescopic arm 10 is telescopic, and one end is arranged on the support plate 7, and the other end is connected to the connecting arm 11, so that the photovoltaic panel 9 is installed at a preset tilt angle. The telescopic arm 10 adopts an electric hydraulic push rod, and the electric hydraulic push rod is also connected to a control switch for convenient control. Further, the support plate, auxiliary frame, photovoltaic panel and telescopic arm are used, and the telescopic arm can be extended and retracted to adjust the angle between the connecting arm and the support plate, and then the size of the photovoltaic panel between the crossbeam and the support plate can be adjusted to adapt to the installation of photovoltaic panels of different specifications and models, and the photovoltaic panel installation of the preset angle can be completed at the same time, which is more practical. At the same time, the power generation equipment of this embodiment is driven by a battery, which is arranged on the base and connected to the photovoltaic panel for energy storage.

[0027] The technical contents of this embodiment are generally similar to those of Embodiment 1, except that: a new type of distributed photovoltaic power generation equipment further includes: the telescopic arm 10 includes a sleeve 20 and a sleeve rod 21. The support plate 7 and the connecting arm 11 are both provided with connecting ears, and there are two sleeve rods 21, which are both hinged to the connecting ears.
