[0025] Embodiment 1

[0026] In order to fold the solar panels in bad weather and store them for protection, the bad weather can prevent the solar panels from being damaged.

[0027] The utility model embodiment introduces an umbrella-type automatic folding solar panel, see Figure 1 , including a platform 4, a guide column 6 is fixedly installed at the center of the end surface of the platform 4, an umbrella cover 10 is fixedly installed on the top of the guide column 6, and a photovoltaic panel 11 is fixedly installed on the top of the umbrella cover 10. The photovoltaic panel 11 converts solar energy into light energy.

[0028] See also Figure 2 The outer wall of the guide column 6 is slidably connected with a ring sleeve 8, and the ring sleeve 8 is connected to the umbrella cover 10 through an umbrella rib 9. The umbrella rib 9 includes a main bracket and an auxiliary bracket. The end of the auxiliary bracket is rotatably connected to the main bracket. The main bracket is fixedly installed at the bottom of the umbrella cover 10, and the end of the main bracket is rotatably connected to the guide column 6, and the end of the auxiliary bracket is rotatably connected to the ring sleeve 8. The umbrella rib 9 divides the umbrella cover 10 into a plurality of fan-shaped surfaces, and two photovoltaic panels 11 are fixedly installed on each fan-shaped surface. The photovoltaic panel 11 adopts a fan-shaped structure, and there is a gap between two adjacent photovoltaic panels 11 to prevent the photovoltaic panels 11 on it from interfering with each other and affecting the folding when the umbrella cover 10 is folded.

[0029] A brush is fixedly installed at the gap between two adjacent photovoltaic panels 11. When the photovoltaic panel 11 is folded, the adjacent gaps move in opposite directions. The brush at the gap cleans the surface of the photovoltaic panel 11 to remove surface attachments to avoid blocking sunlight from irradiating the photovoltaic panel 11. A rubber strip is fixedly installed at the top edge of the photovoltaic panel 11. When the photovoltaic panel 11 is folded, the rubber strip can reduce the collision between the two adjacent photovoltaic panels 11 to avoid damage to the photovoltaic panel 11.

[0030] See also Figure 2 The other end of the guide column 6 is fixedly connected to the platform 4, and the platform 4 is fixedly connected to the ring sleeve 8 through the second electric push rod 7. When unfolding, the second electric push rod 7 extends to push the ring sleeve 8 toward the umbrella cover 10, and the ring sleeve 8 moves and uses the umbrella ribs 9 to unfold the umbrella cover 10, thereby unfolding the photovoltaic panel 11, so that the photovoltaic panel 11 can absorb solar energy better; when folding, please refer to Figure 3 The second electric push rod 7 is contracted to move the ring sleeve 8 away from the umbrella cover 10. The ring sleeve 8 moves and the umbrella cover 10 is contracted and folded by the umbrella ribs 9, thereby reducing the unfolded area of ​​the photovoltaic panel 11, that is, reducing the footprint of the photovoltaic panel 11 and the umbrella cover 10, so as to facilitate transportation and movement.

[0031] See also Figure 2 A sensor group 12 is fixedly mounted on the top surface of the umbrella cover 10. The sensor group 12 includes a rain sensor, a wind speed sensor, a light intensity sensor and a photosensor. The sensor group 12 is electrically connected to the second electric push rod 7 through a controller and a single-chip microcomputer. The STC89C52 single-chip microcomputer is selected as the main controller. The sensor group 12 and the single-chip microcomputer use the I2C bus for data transmission. After receiving the external environment signal, a control signal is generated through a C language program and sent to the motor drive circuit, thereby providing power for the second electric push rod 7, thereby controlling the unfolding and folding of the photovoltaic panel 11.

[0032] See also Figure 1 The end of the platform 4 is rotatably connected to the first electric push rod 3, the end of the first electric push rod 3 is fixedly installed with a base 1, the top of the base 1 is fixedly installed with a storage bin 2, and the storage bin 2 is sleeved on the outside of the first electric push rod 3. When the rainfall exceeds the set value or the wind speed exceeds the set value, and the photovoltaic panel 11 is folded, the first electric push rod 3 will retract and store the folded photovoltaic panel 11 into the storage bin 2.

[0033] See also Figure 5 A closing cover 13 is fixedly installed between the umbrella cover 10 and the sensor group 12. After the photovoltaic panel 11 is completely received in the receiving bin 2, the closing cover 13 is covered on the top of the receiving bin 2 to seal it, so as to prevent rain, snow and hail from entering the receiving bin 2 and causing damage to the photovoltaic panel 11.

[0034] The umbrella-type automatic folding solar panel introduced in the embodiment of the utility model, when the rain sensor senses that the rainfall exceeds the set value or the wind speed sensor senses that the wind speed exceeds the set value, the rain sensor or the wind speed sensor transmits the information to the single-chip microcomputer and the controller, thereby controlling the second electric push rod 7 to contract to move the ring sleeve 8, the ring sleeve 8 moves and uses the umbrella ribs 9 to fold the umbrella cover 10, thereby folding the photovoltaic panel 11, after the photovoltaic panel 11 is folded, the first electric push rod 3 contracts to store the photovoltaic panel 11 in the storage bin 2 for storage and protection, to avoid rain, snow, wind, sand and hail in bad weather, which will hit the solar panel and cause damage to the solar panel, shorten its life and reduce its use effect.

[0035] Embodiment 2

[0036] In order to adjust the angle of the photovoltaic panel 11 to track the sun, the light intensity received by the photovoltaic panel 11 is increased.

[0038] When the rain sensor senses that the rainfall exceeds the set value or the wind speed sensor senses that the wind speed exceeds the set value, the rain sensor or the wind speed sensor transmits the information to the single chip microcomputer and the controller. The controller first controls the stepper motor 5 to rotate so that the guide column 6 and the axis of the first electric push rod 3 are on the same straight line, and then folds the photovoltaic panel 11 to prevent the guide column 6 from tilting and causing the photovoltaic panel 11 to be unable to be stored in the storage bin 2.

[0039] The umbrella-type automatic folding solar panel introduced in the utility model obtains the light intensity information on both sides of the solar panel through the light intensity sensor, and transmits the information to the single-chip microcomputer and the controller, so as to adjust the inclination angle of the guide column 6 by rotating the stepper motor 5, that is, to change the inclination angle of the photovoltaic panel 11, so that the photovoltaic panel 11 tracks the sun, thereby improving the photovoltaic panel 11's reception effect on solar energy.
