Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a wind and snow resistant photovoltaic component. Background Art

[0002] Photovoltaic power generation plays an important role in my country. my country's photovoltaic power generation has increased year by year, and the use of solar panels is also very popular. Solar panels are generally installed in places with sufficient sunlight. The installed components generally use metal frames and are fixed with bolts.

[0003] Photovoltaic power generation devices are generally installed in high locations outdoors, such as plateaus and rooftops. Although these places have long hours of sunlight and sufficient light, in some harsh environments, such as strong winds and heavy snow, the strength of existing photovoltaic modules is poor and they are easily overturned and damaged in strong winds and heavy snow.

[0004] Therefore, in order to solve the problem that photovoltaic modules are easily overturned and damaged in the harsh environment of strong winds and heavy snow, a photovoltaic module that can change the direction of force is designed to avoid the problem of photovoltaic modules being damaged in the environment of strong winds and heavy snow. Utility Model Content

[0005] In order to overcome the problem that photovoltaic modules are easily overturned and damaged in existing windy and snowy environments.

[0006] The technical solution of the utility model is: a wind and snow resistant photovoltaic component, including a base plate and a solar panel; also including a slot, a block and a handle, the solar panel is rotatably mounted on the base plate, the base plate is symmetrically provided with slots, a block is rotatably arranged in the slot, a handle is fixedly mounted on one side of the base plate, protection mechanisms for protecting the solar panel by changing the force-bearing area are provided on both sides of the base plate, and a rotating mechanism for adjusting the position according to the direction of light is provided on the upper end of the base plate.

[0007] Preferably, the base is first fixed in the desired position by bolts. In a strong wind environment outdoors, the solar panels are very easy to be overturned and damaged. When the solar panels are subjected to strong winds, the solar panels rotate immediately, and the angle of the solar panels changes. The tilt angle changes with the strength of the wind, thereby preventing the solar panels from being overturned by strong winds. The position of the sun will change over time, and the rotating mechanism makes the solar panels always face the light, thereby improving the utilization rate of light. During the rotation of the solar panels, the snow that falls on the solar panels can also be shaken off.

[0008] Preferably, the protection mechanism includes a connecting arm, a slider, a baffle, a slide groove and a spring. The two sides of the solar panel are rotatably connected to the connecting arm, and the lower end of the connecting arm is rotatably connected to the slider. The baffles are symmetrically fixedly connected to the two sides of the base plate. The slide grooves are symmetrically fixedly installed on both sides of the base plate, and the slide grooves are arranged inside the base plate. A spring is placed in the slide groove. When the solar panel is exposed to strong winds, the solar panel rotates immediately, and the solar panel rotates while driving the connecting arm to rotate. The connecting arm also drives the slider to move in the slide groove. The angle of the solar panel changes, and the tilt angle changes with the strength of the wind, thereby preventing the solar panel from being overturned by strong winds.

[0009] Preferably, the slider is slidably connected to the slide groove, and the end of the slider is fixedly connected to one end of the spring. The baffle is set at the end of the slide groove. The connecting arm drives the solar panel to rotate while the slider moves. After the strong wind, the slider returns to its initial position under the action of the spring, and the baffle holds the slider in place, ensuring that the solar panel can rotate flexibly while ensuring the structural strength.

[0010] Preferably, a drainage hole is provided at the lower end of the chute, and the drainage hole at the lower end of the chute is set through the bottom surface of the base plate. On rainy days, water entering the chute flows out from the drainage hole to prevent rainwater from accumulating in the chute and causing corrosion of the spring.

[0011] Preferably, the rotating mechanism includes a battery, a photoresistor, an electromagnetic switch, a micromotor, a rotating shaft, a transmission gear, a base and a support base. The upper end of the base plate is fixedly installed with a battery, the upper end of the base plate is fixedly connected to the photoresistor, the upper end of the base plate is fixedly connected to the electromagnetic switch, the upper end of the base plate is fixedly connected to the micromotor, the output shaft end of the micromotor is fixedly connected to the rotating shaft, and the rotating shaft is arranged through the bottom surface of the base plate, the lower end of the rotating shaft is fixedly connected to the transmission gear, the lower end of the base plate is rotatably connected to the support base, and the lower end of the support base is fixedly connected to the base. When the photoresistor is blocked by the solar panel and cannot be exposed to sunlight, the resistance is large and the electromagnetic switch is closed. When the light goes around the back of the solar panel, the photoresistor is exposed to light, the resistance becomes smaller, the electromagnetic switch is started, and the micromotor is started at the same time. The micromotor drives the rotating shaft to rotate, and the transmission gear below the rotating shaft makes a circular motion around the center of the disk of the base. The base plate rotates simultaneously on the support base. When the solar panel blocks the light again, the resistance of the photoresistor becomes larger and the electromagnetic switch is closed.

[0012] Preferably, one end of the battery is connected to the solar panel through a circuit, the other end of the battery is connected to one end of the photoresistor through a circuit, and the other end of the photoresistor is connected to the electromagnetic switch through a circuit. The electromagnetic switch is used to control the start and shut down of the micro motor. The solar panel provides electrical energy to the battery. The characteristics of the photoresistor are utilized to ensure that the solar panel is always facing the light, thereby improving the utilization rate of the light.

[0013] Preferably, the transmission gear is meshed with the base, the base is disc-shaped, and the transmission gear moves in a circular motion around the center of the disc of the base under the drive of the micro motor. The surface of the base is provided with holes for bolts to pass through, which facilitates the rotation of the base plate and changes the angle as the light position changes. The base is fixed in the desired position by bolts.

[0014] The beneficial effects of the utility model are:

[0015] 1. When the solar panel is exposed to strong winds, the solar panel will rotate immediately, and the rotation of the solar panel will drive the connecting arm to rotate. The connecting arm will also drive the slider to move in the slide slot, and the angle of the solar panel will change. The tilt angle will change with the strength of the wind, thereby preventing the solar panel from being overturned by the strong wind. The utility model can be folded, and the solar panel can be rotated into the slot. The handle can be picked up to transport the utility model to the desired location. During the transportation process, the block prevents the solar panel from falling out of the slot, making it easy to carry.

[0016] 2. When the photoresistor is blocked by the solar panel and cannot be exposed to sunlight, the electromagnetic switch is closed. When the light goes around the back of the solar panel, the resistance becomes smaller, the electromagnetic switch is started, and the micro motor is started at the same time. The transmission gear moves in a circle around the center of the base disc. When the solar panel blocks the light again, the electromagnetic switch is closed. In this way, the solar panel can always face the light, improving the utilization rate of light. During the rotation of the solar panel, the snow that falls on the solar panel can also be shaken off.
