The rotation of the motor drives the solar panel to be retracted into the shell to avoid damage to the solar panel caused by strong wind. When there is heavy rain or heavy snow, rain and snow enter the water tank through the water inlet.

Similarly, the battery is used to energize the fixed motor through the delay relay to retract the solar panel into the shell to prevent the solar panel from being corroded by rain. When the wind speed decreases or the rainfall decreases, the swing arm does not contact the pressure sensor, and the upward contact of the water tank is disconnected. After one hour, the delay relay energizes the circuit to reverse the fixed motor so that the solar panel can be moved to the outside of the shell for continued use. The advantage of this is that the solar panels can be effectively protected under the influence of extreme weather, the impact of weather on the solar panels can be reduced, and the service life of the solar panels can be effectively extended.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0022] See also Figure 1-5The present invention provides a technical solution: a solar photovoltaic power generation building guardrail, including a fan blade 7, a swing rod 8, a shell 5, a fixed spring 4, a water tank 2, a battery 18, a fixed motor 19, a threaded rod 12 and a fixed slider 15. The fan blade 7 is used to detect strong wind weather. When strong wind weather occurs, the fan blade 7 will rotate with the strong wind, and the swing rod 8 will also swing with the fan blade 7. When the rotation of the fan blade 7 reaches a value, one end of the swing rod 8 can contact the pressure sensor on the inner wall of the connecting sleeve 6. The pressure sensor converts the received signal into an electrical signal, and starts the delay relay to form a closed loop with the battery 18 and the fixed motor 19. The model of the delay relay is: MD1FNS1. The continuous contact between the swing rod 8 and the pressure sensor will refresh the period of reverse power supply between the delay relay and the fixed motor 19. When the wind speed decreases or stops, the swing rod 8 does not Contacting with the pressure sensor, the time delay relay starts the fixed motor 19 after one hour, and pushes the solar panel 10 to the outside of the shell 5 through the rotation connection between the fixed slider 15 and the threaded rod 12. When there is heavy rain or heavy snow, rain and snow enter the water tank 2 through the water inlet 3, and the bottom of the water tank 2 is drained through the water outlet 1. Since the water inlet is greater than the water outlet, the weight of the water tank 2 increases, so that the water tank 2 drives the sliding rod 22 to move downward, and the sliding rod 22 contacts with the contacts inside the connecting groove 21 to form a closed circuit. Similarly, the battery 18 is powered by the time delay relay to energize the fixed motor 19 to retract the solar panel 10 into the shell 5. When the rainfall decreases or stops, the time delay relay starts the fixed motor 19 after one hour, and pushes the solar panel 10 to the outside of the shell 5 through the rotation connection between the fixed slider 15 and the threaded rod 12.

[0023] A shell 5 is fixed to one end of the fence 9, a connecting sleeve 6 is fixed to one end of the shell 5, a fan blade 7 is rotatably connected to one end of the shell 5, the fan blade 7 is sleeved inside the connecting sleeve 6, a rocker arm 8 is rotatably connected to one end of the fan blade 7, a fixing spring 4 is fixed to one end of the rocker arm 8, and the other end of the fixing spring 4 is fixedly connected to the fan blade 7, a connecting groove 21 is provided at one end of the shell 5, a sliding rod 22 is slidably connected to the inside of the connecting groove 21, a reset spring 23 is fixed to the upper end of the sliding rod 22, and the other end of the reset spring 23 is fixedly connected to the upper inner wall of the connecting groove 21.

[0024] A water tank 2 is provided at one end of the shell 5, the outer wall of one end of the sliding rod 22 passes through the connecting groove 21 and is fixedly connected to the outer wall of the water tank 2, a supporting wheel 24 is fixed at one end of the water tank 2, and the other end of the supporting wheel 24 is in contact with the outer wall of the shell 5, a water inlet 3 is provided at the upper end of the water tank 2, a filter screen 11 is fixed inside the water inlet 3, and a water outlet 1 is provided at the lower end of the water tank 2.

[0025] A battery 18 is fixed on the inner wall of one end of the shell 5, a fixed motor 19 is fixed on the inner wall of one end of the shell 5, a slide plate 14 is fixed on the outer wall of one end of the fence 9, a threaded rod 12 is rotatably provided inside the slide plate 14, a transmission belt 20 is fixedly sleeved on the output end of the fixed motor 19, the other end of the transmission belt 20 is fixedly sleeved on the outside of the threaded rod 12, a driven slider 13 is slidably sleeved on the outside of the slide plate 14, a fixed slider 15 is slidably sleeved on the outside of the slide plate 14, the fixed slider 15 and the threaded rod 12 are spirally connected, a telescopic rod 16 is fixed on one end of the fixed slider 15, the telescopic end of the telescopic rod 16 is rotatably connected to a connecting seat 17, the other end of the connecting seat 17 is fixedly connected to a solar panel 10, and the fixed motor 19 is electrically connected to the solar panel 10 through the battery 18.

[0026] In order to increase the power generation, four groups of solar panels 10 are arranged. The four groups of solar panels 10 are rotatably connected by hinges. The internal space width of the shell 5 is greater than the width of the solar panels 10. The four solar panels 10 working at the same time can absorb solar energy to generate a large amount of electricity, and the energy-saving effect is better.

[0027] In order to store water for use, the opening diameter of the water inlet 3 is much larger than the opening diameter of the water outlet 1. Electric heating wires are fixed on the inner walls at both ends of the water tank 2. The input end of the electric heating wire is electrically connected to the battery 18, so that water can be stored inside the water tank 2 when the rainfall is heavy. The electric heating wire is used to melt the snow stored inside into water and discharge it from the water outlet 1 in heavy snow weather.

[0028] In order to convert the strong wind signal into an electrical signal, a pressure sensor is fixed on the inner wall of the connecting sleeve 6. When the pendulum rod 8 rotates around the fan blade 7, there is a point where one end of the pendulum rod 8 contacts the pressure sensor. The output end of the pressure sensor is electrically connected to the controller, and the output end of the controller is electrically connected to the fixed motor 19. When the wind is not strong enough, the pendulum rod 8 does not rotate enough to contact the pressure sensor, and the circuit will not be closed. In this way, it can be determined whether to retract the solar panel 10 into the shell 5 according to the wind speed.

[0029] In order to adjust the position of the solar panel 10 according to the rainfall, a circuit opening and closing contact is fixed on the inner wall of the lower end of the connecting groove 21, and a conductive block is fixed on the lower end of the sliding rod 22. After the conductive block contacts the contact, the circuit forms a closed loop. When the rainfall is large and the water inlet of the water tank 2 is greater than the water outlet, rainwater will be stored inside the water tank 2, causing the weight to increase, so that the sliding rod 22 slides down and contacts the connecting groove 21 to form a closed loop. When the rainfall decreases or stops, the reset spring 23 acts to disconnect the reset circuit of the small water tank 2.

[0030] In order to prevent water from accumulating inside the shell 5, the inner wall of the lower end of the shell 5 is an inclined smooth wall, and the shell 5 and the fence 9 are fixedly connected by bolts, so that rainwater will not accumulate inside the shell 5 in rainy and snowy weather, and rainwater will flow out along the inclined outer wall to prevent the solar panel 10 from getting wet.

[0031] In order to achieve automatic adjustment, the elastic force of the return spring 23 is greater than the gravity of the water tank 2, and the outer wall of the sliding rod 22 and the inner wall of the connecting groove 21 can fit completely, so that the water tank 2 will not slide down when there is no rainwater accumulated.

[0032] Working principle: The two groups of branches connected by the swing rod 8 and the water tank 2 are connected in parallel and electrically connected to the battery 18 and the fixed motor 19, which can detect extreme weather such as strong winds, rain and snow. When the detection result reaches a predetermined value, a closed loop will be formed to retract the solar panel 10 into the shell 5 through the fixed motor 19 for protection.

[0033] 1. When there is strong wind, the fan blade 7 will rotate with the strong wind, and the swing rod 8 will also swing with the fan blade 7. When the fan blade 7 rotates to a certain value, one end of the swing rod 8 can contact the pressure sensor on the inner wall of the connecting sleeve 6. The pressure sensor converts the signal into an electrical signal after receiving it, and starts the delay relay so that the battery 18 and the fixed motor 19 form a closed loop. The fixed motor 19 drives the threaded rod 12 to rotate, so that the fixed slider 15 spirally connected to the threaded rod 12 moves toward the housing 5, and after the solar panel 10 is squeezed and folded, the fixed slider 15 connects the solar panel 10 and moves to the inside of the housing 5 to prevent the strong wind from affecting the solar panel 10. When the swing rod 8 is affected by the wind and keeps in contact with the pressure sensor, the reverse power-on cycle of the delay relay will be refreshed. When the wind decreases or stops, the swing rod 8 is not in contact with the pressure sensor, the delay relay does not receive the signal and reversely powers the fixed motor 19 after one hour, so that the fixed motor 19 reverses, and the fixed slider 15 moves to the other end along the threaded rod 12, and the solar panel 10 is opened to receive sunlight for power generation.

[0034] 2. When it rains heavily or snows heavily, rain and snow enter the water tank 2 through the water inlet 3 and are discharged from the water outlet 1 at the bottom. There is an electric heating wire inside the water tank 2, which will melt the accumulated snow into water and discharge it. Since the water inflow is greater than the water outflow, the weight of the water tank 2 increases, causing the water tank 2 to drive the sliding rod 22 to move downward. The sliding rod 22 contacts the contact inside the connecting groove 21 to form a closed circuit. The circuit of this contact is a branch connected in parallel with the pressure sensor circuit. The kinetic energy generated after closing is the same, and the solar panel 10 is repeatedly retracted into the shell 5 through the fixed motor 19. When the rainfall decreases or stops, the accumulated rainwater in the water tank 2 is discharged, and the reset spring 23 drives the water tank 2 to move upward. The contact is disconnected, and the delay relay on this branch does not receive a signal continuously and reversely energizes the fixed motor 19 after one hour, so that the fixed motor 19 reverses and moves the fixed slider 15 to the other end along the threaded rod 12. The solar panel 10 is opened to receive sunlight for power generation.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
