When the device needs to be moved, the button is pressed again to move the fixing block, pushing the bottom plate inward to a specified position, so that the fixing block re-fixes the bottom plate. This design allows the device to be quickly stored when it needs to be moved, and is protected by a shell when moving, so that it will not be hit during movement, causing damage to the surface or internal parts of the solar photovoltaic panel.

[0027] In some embodiments, the bottom wall of the guide block is inclined, and the bottom of the guide block is serrated.

[0028] Compared with the prior art, the present invention has the following significant advantages:

[0029] First, the present invention arranges the photovoltaic panel outside to facilitate the sun's radiation on the side wall of the photovoltaic panel. Through the cooperation between the photovoltaic panel and the photovoltaic inverter, the light energy is converted into electrical energy, which is stably input into the photovoltaic inverter, and the electrical energy is stored by the battery. The positioning screw is rotated and installed on the side wall of the push plate through the fixed bearing. Since the bottom wall of the guide block is inclined, when the positioning screw rotates, the push plate pushes the photovoltaic panel to rotate upward around the connecting shaft under the guidance of the guide block, so as to achieve the effect of adjusting the angle of the photovoltaic panel, which facilitates the sun's radiation on the side wall of the photovoltaic panel. Through the rotation of the handle screw and the deformation screw, the turntable can be stuck in the inside of the positioning slot. At this time, the device can be lifted by the handle screw, which is convenient for carrying the device. By arranging the photovoltaic panel on the top of the storage box, the adjustable angle of the photovoltaic panel is improved. By adjusting the component, the inclination angle of the photovoltaic panel can be conveniently adjusted, and the device is also convenient to carry. It solves the problem that it is difficult to make full use of the internal space of the protective box.

[0030] Secondly: The present invention supports the position of the battery by multiple shielding rods, side rods, pads and side plates to ensure the stability of the battery position. At the same time, the gaps between the multiple shielding rods, side rods, pads and side plates facilitate the air flow inside the storage box, facilitate the heat dissipation of the battery inside the storage box, and avoid the situation where the battery temperature is too high and affects the energy storage efficiency; by fitting the side wall of the rolling ball with the side wall of the photovoltaic inverter, since the side rods are in an arc shape and the side plates are in a mesh shape, the side rods and side plates have a certain elasticity, so the side rods and side plates can buffer the shaking of the battery, and at the same time, the displacement of the battery further increases the flow rate of the air inside the storage box.

[0031] Thirdly, the present invention makes the side wall of the rolling ball fit with the side wall of the photovoltaic inverter. Since the side rods are in an arc shape and the side plates are in a mesh shape, the side rods and the side plates have a certain elasticity, so the side rods and the side plates can buffer the shaking of the battery, and at the same time further increase the flow speed of the air inside the storage box through the displacement of the battery; the cleaning brush is rotatably installed on the side wall of the cleaning rod by connecting the swivel. When the angle of the photovoltaic panel is tilted, the cleaning brush can always fit with the side wall of the photovoltaic panel, thereby ensuring the cleaning effect of the cleaning brush on the side wall of the photovoltaic panel.

[0032] Fourthly, in the present invention, when the angle of the photovoltaic panel is tilted, the cleaning rod slides inside the accommodating groove under the guidance of the side wall of the photovoltaic panel. Under the restriction of the cleaning rod and the push plate, the angle of the photovoltaic panel can be kept stable. When the photovoltaic panel is stored inside the storage box, the cleaning rod is driven to move by the elasticity of the reset spring, so that the cleaning rod moves to a position aligned with the push plate. During the reset process, the cleaning rod can also clean the side wall of the photovoltaic panel to ensure the cleanliness of the side wall of the photovoltaic panel.

[0033] Fifth: The present invention increases the height of the side wall of the storage box by using the support legs, and places the support legs and the positioning slots in the same plane, which facilitates the accommodation of the turntable and avoids the situation where the side wall of the storage box is uneven due to the turntable and it is difficult to place the device; the interior and exterior of the storage box are connected by the ventilation net, which facilitates the discharge of air inside the storage box to the outside and improves the heat dissipation efficiency inside the storage box.
