Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic structures, in particular to a distributed photovoltaic structure applied to power distribution networks. Background Technique

[0002] Photovoltaic: It is short for solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar light radiation energy into electrical energy. It has two operation modes: independent operation and grid-connected operation. At the same time, the solar photovoltaic power generation system can be classified into two types: one is centralized, such as large-scale northwest ground photovoltaic power generation systems; the other is distributed, such as industrial and commercial enterprise factory roof photovoltaic power generation systems and residential roof photovoltaic power generation systems.

[0003] After the existing distributed photovoltaic structure applied to power distribution networks is installed, it is not convenient to adjust the inclination angle of the photovoltaic, which reduces the utilization rate of light energy, and it cannot be applied to the installation of photovoltaic panels of different sizes, having certain limitations. Therefore, we design a distributed photovoltaic structure applied to power distribution networks to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a distributed photovoltaic structure applied to power distribution networks to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A distributed photovoltaic structure applied to power distribution networks includes a bottom plate. A circular plate is rotatably arranged on the top of the bottom plate. One side of the top of the circular plate is rotatably connected with a mounting plate through two support plates. A support assembly for supporting the mounting plate is arranged on the other side of the top of the circular plate. A limiting assembly is also arranged on the top of the circular plate. The photovoltaic panel is detachably mounted on the top surface of the mounting plate. A fixed baffle is fixedly arranged at the rear side of the top surface of the mounting plate. A movable baffle is slidably arranged at the front side of the top surface of the mounting plate. A plurality of first mounting holes are arranged on both the fixed baffle and the movable baffle. A slider is arranged at the middle position of the bottom of the movable baffle. A chute for the slider to slide and be embedded is formed on the top surface of the mounting plate. A threaded rod is rotatably arranged in the chute. The slider is threadedly sleeved on the outside of the threaded rod. The front end of the threaded rod penetrates to the outside of the chute and is connected with a turning knob. The turning knob is rotatably arranged on the front side surface of the mounting plate. Two groups of second mounting holes are symmetrically arranged on the front and rear side surfaces of the photovoltaic panel. The number of each group of second mounting holes is two, and the two second mounting holes are symmetrically distributed at the left and right ends of the side surface of the photovoltaic panel. Mounting bolts adapted to the second mounting holes are threadedly inserted into the second mounting holes, and the mounting bolts are also adapted to the first mounting holes.

[0007] As a preferred embodiment of the present utility model: The support assembly includes a first hinge seat fixedly arranged on the top of the circular plate. The first hinge seat is movably connected with an outer rod. A slot is formed on the end surface of the other end of the outer rod, and an inner rod is slidably inserted into the slot.

A fixing bolt is threadedly inserted into the upper part of the outer surface of the outer rod, and a plurality of screw holes are formed on the outer surface of the inner rod and are matched with the fixing bolt.

[0008] As a further preferred embodiment of the present utility model: The limiting assembly includes a plug rod slidably inserted through the top of the circular plate.

One end of the spring is connected to the top of the circular plate, and the other end is connected to the bottom of the top block.

[0009] As a further preferred embodiment of the present utility model: Two convex blocks are further arranged at the bottom of the movable baffle. A guiding groove for the convex blocks to slide and be embedded is formed on the top surface of the mounting plate. The two convex blocks are symmetrically distributed on the left and right sides of the slider.

[0010] As a further preferred embodiment of the present utility model: The plurality of screw holes are equally spaced along the length direction of the inner rod.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. When installing this device, the staff can drive the threaded rod to rotate through the knob, thereby driving the slider to move, and then driving the movable baffle to move. Therefore, the distance between the fixed baffle and the movable baffle can be controlled. Place the photovoltaic panel between the fixed baffle and the movable baffle, and control the movable baffle to move until it clamps the photovoltaic panel. Note that the second mounting holes on the surface of the photovoltaic panel should be aligned with the corresponding first mounting holes. Then, insert the mounting bolts into the first mounting holes and connect them to the corresponding second mounting holes, thereby completing the installation of the photovoltaic panel.

[0015] 2. When the device is in use, adjust the rotation angle of the mounting plate to a suitable position, that is, adjust the rotation angle of the photovoltaic panel in the vertical direction. This process can drive the inner rod to slide in the slot. When the position is determined, the fixing bolt can be screwed to make the fixing bolt embed into the corresponding screw hole to fix the position of the inner rod. Subsequently, the staff can pull up the insertion rod through the top block to separate the insertion rod from the limiting hole. At this time, the circular plate can be rotated, and then the rotation angle of the photovoltaic panel in the horizontal direction can be adjusted. Finally, release the top block. Under the action of the spring elasticity, drive the insertion rod to embed into the corresponding limiting hole for limit clamping to prevent the circular plate from rotating, that is, fix the position of the photovoltaic panel. Therefore, this device can adjust the installation angle of the photovoltaic panel from two directions, the vertical direction and the horizontal direction, which can better adapt to different angles of sunlight, thus improving the utilization efficiency of solar energy.

Therefore, this device can adjust the installation angle of the photovoltaic panel 9 in two directions, the vertical direction and the horizontal direction, and can better adapt to different angles of sunlight, thereby improving the utilization efficiency of solar energy.
