Description

Technical Field

[0001] The invention relates to a protection device, in particular to a protection device for a photovoltaic power generation solar panel. Background Art

[0002] Solar panels are important equipment for photovoltaic power generation, and their quality is directly related to the efficiency of photovoltaic power generation and the utilization rate of solar energy.

[0003] However, solar panels are installed outdoors. In order to fully absorb solar energy, their surfaces are unobstructed and they are fixed in one place for a long time. This will cause the solar panels to be damaged by long-term wind and sun, shortening their service life.

[0004] Therefore, how to protect photovoltaic solar panels has become a technical problem that needs to be solved. Summary of the invention

[0005] The purpose of the present invention is to provide a protective device for photovoltaic solar panels in order to overcome the defects of the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A protective device for a photovoltaic solar panel, the protective device comprising protective structures symmetrically arranged on both sides of the upper surface of the solar panel; the protective structure comprising a transverse bracket welded to the side of the solar panel; a vertical bracket movable along the transverse bracket is arranged on the transverse bracket; a shielding plate is arranged on the top of the vertical bracket; the size of the shielding plate is exactly equal to half the size of the solar panel; a photosensor is arranged on the top of the shielding plate; the photosensor is connected to a controller; and the controller is fixed on the top of the shielding plate.

[0008] Furthermore, the horizontal bracket is provided with two slide grooves; the vertical bracket is provided with two pulleys used in conjunction with the slide grooves; the two pulleys are fixed on the same rotating shaft; the rotating shaft is rotatably connected to the vertical bracket; the two pulleys are respectively placed in the two slide grooves.

[0009] Furthermore, a motor is fixed to one end of the vertical bracket; the rotating end of the motor is connected to the rotating shaft to drive the rotating shaft to rotate; the motor is connected to a controller and is started by the controller.

[0010] Furthermore, the motor is a servo motor that can realize forward and reverse rotation.

[0011] Furthermore, a support rod is fixed between the vertical support and the shielding plate; a triangular support structure is formed between the support rod, the vertical support and the shielding plate.

[0012] Furthermore, vertical baffles are provided at both ends of the baffle plate to shield and protect the upper and lower sides of the solar panels.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The present invention senses the intensity of sunlight through a photosensitive sensor. When the sun sets and no longer shines, the photosensitive sensor sends a signal to a controller, and the controller controls the motor to rotate forward so that the shielding plate shields the surface of the solar panel, thereby providing protection at night. After the sun comes out during the day, the photosensitive sensor sends a signal to the controller again, and the controller controls the motor to reverse and open the shielding plate, so that the sun shines on the surface of the solar panel to perform photovoltaic power generation, thereby better protecting the solar panel and extending its service life.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0022] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
