The reflecting unit 2 is located on the sun-back side of the photovoltaic panel 1, and the reflecting unit 2 reflects sunlight to enable the sun-back side of the photovoltaic panel 1 to be irradiated by the sunlight. The reflection unit 2 includes a first plate 201, a second plate 202, and a third plate 203. The reverse plate 201 is arranged in parallel on the sun-back side of the photovoltaic panel 1. The reverse two plate 202 and the reverse three plate 203 are respectively connected to the left and right sides of the reverse one plate 201 in a rotating manner. The sunlight irradiated on the reflective plate 202 is projected within the first light zone 101 by direct reflection or re-reflection through the reflective plate 201. The sunlight irradiated on the reflective three-plate 203 is projected within the light two-zone 102 in a manner of direct reflection or re-reflection through the reflective one-plate 201.

One fan blade 205 is fixed on the periphery of one end of the rotating shaft 204. The reverse three plate 203 is rotatably connected with the right side of the reverse one plate 201 through a rotating two shaft 206. Two fan blades 207 are fixedly arranged on the periphery of one end of the two rotating shafts 206.

The heating unit 2 is powered by the storage battery 4 to generate heat and transfer the heat to external sludge drying equipment. The heating unit 3 includes a heating group 301, a heating group 302, and a controller 5. The heating group 301 and the heating group 302 can be heated independently. The controller 5 is electrically connected with the photovoltaic panel 1. When the light-first region 101 receives light radiation, the controller 5 controls the heating group 301 to heat. When the second light zone 102 receives light radiation, the controller 5 controls the heating group 302 to heat. When the light source 101 and the light source 102 receive the light radiation, the controller 5 controls the heating group 301 and the heating group 302 to heat simultaneously.

Heating group 301 includes tank 303, air pipe 304, heat pipe 305, and solenoid valve 306. The heat pipe 305 is located in the case 303 and electrically connected to the battery 4. The lower end of the box 303 is provided with an air inlet check valve 308, and the air inlet check valve 308 only allows outside air to enter the box 303. The upper end of the box 303 is provided with an air outlet one-way valve 307, and the air outlet one-way valve 307 only allows the air in the box 303 to be exhausted outside. The air pipe 304 is fixedly arranged at the upper end of the box body 303 and is communicated with the air outlet one-way valve 307.

The air inlet and the air outlet of the box 303 of the heating group 301 are both one-way channels, and when the electromagnetic valve 306 is closed, the box 303 is a closed environment. When the heat pipe 305 heats continuously, the gas in the box 303 expands due to heating, if the electromagnetic valve 306 is opened at this time, since the gas pressure in the box 303 is greater than the external gas pressure due to heating, the heated gas is discharged through the gas outlet check valve 307 and the gas pipe 304, the fan blade 205 is pushed to rotate, after the heated gas is discharged, the gas pressure in the box 303 is reduced, when the gas is discharged too much, the heating effect of the heat pipe 305 cannot make the gas pressure in the box 303 equal to the external gas pressure, the external air is supplemented into the box 303 from the gas inlet check valve, so as to maintain the gas spraying circulation.

Heated gas is discharged from the gas pipe 304, the fan blade 205 is pushed to rotate, so that the reverse two plates 202 rotate, the time interval for starting the electromagnetic valve 306 is controlled by the controller 5, the heat pipe 305 continuously works all the time under the power-on condition, so that the heating efficiency is constant, the gas pressure rising ratio is linear, the controller 5 can set the flow and the kinetic energy of the gas discharged from the box 303 by calculating the time interval, so that the accuracy of the rotation angle of the fan blade is ensured, the projection position of the sunlight reflected by the reverse two plates 202 is adjusted, the sunlight always falls into the light-one zone 101, and the effective utilization of the sunlight is effectively ensured.

The heating group 302 and the heating group 301 are the same components in structure. The air tubes 304 of the heating group 302 are aligned with the two blades 207 of the fan. The principle of the reflection adjustment mechanism of the counter three plate 203 is identical to that of the counter two plate 202.

The second embodiment is as follows: in the first embodiment, please refer to the solar sludge drying apparatus of fig. 8-12, the left and right edges of the first light zone 101 and the second light zone 102 are respectively provided with a light partition 103. The optical sub-areas 103 are all electrically connected with the controller 5.

After the light splitting area 103 of the first light area 101 is irradiated by sunlight, the controller 5 controls the electromagnetic valves 306 of the heating group 301 to open, so that heated gas in the box 303 is sprayed out, the sprayed gas acts on the first fan blade 205, the first fan blade 205 drives the rotating shaft 204 to rotate, the second reflecting plate 202 deflects relative to the photovoltaic plate 1, and the reflected light is always located in the first light area 101.

After the light splitting area 103 of the second light area 102 is irradiated by sunlight, the controller 5 controls the electromagnetic valves 306 of the heating two groups 302 to open, so that heated gas in the box 303 is sprayed out, the sprayed gas acts on the two fan blades 207, the two fan blades 207 drive the rotating two shafts 206 to rotate, the reverse three plates 203 deflect relative to the photovoltaic plate 1, and the reflected light is always located in the second light area 102.

Since the sun is very far from the earth and the volume of the sun is far beyond the volume of the earth, it can be said that sunlight irradiates the earth in the form of parallel light. The sun is always east-rising-west, as viewed on the earth, based on the earth's rotation direction being constant. In the northern hemisphere, the sun is always located in the south, so the sunny side of the photovoltaic panel 1 of the present invention faces the south, and the reflection unit is located in the north of the photovoltaic panel 1.

When the sun just rises, sunlight irradiates from east to west, the photovoltaic panel 1 is parallel to the sunlight irradiation angle, the reverse second panel 202 is arranged close to the photovoltaic panel 1, and the sunlight irradiates to the reverse first panel 201 after being reflected by the reverse second panel 202 and then is reflected to the first light area 101.

When the sun gradually deflects toward the west, the sunlight irradiates the reflective three-plate 203 and is directly reflected to the light two-zone 102. At this time, after the sunlight irradiates on the first light zone 101, the projection point on the first light zone 101 is located close to the edge of the first light zone 101, and after the light subarea 103 of the first light zone 101 irradiates on the sunlight, the controller 5 drives the heating group 301 to discharge hot air, so that the second reflecting plate 202 deflects outwards, and the angle between the second reflecting plate and the photovoltaic panel 1 is adjusted, so that the sunlight reflection point is always located in the first light zone 101. The sunlight irradiated on the reverse three-plate 203 gradually approaches the edge of the second light zone 102 along with the shift of the sun toward the west, and after the light splitting zone 103 of the second light zone 102 irradiates the sunlight, the controller 5 drives the heating two groups 302 to exhaust hot air, so that the reverse three-plate 203 deflects inward, and the angle between the reverse three-plate 203 and the photovoltaic panel 1 is adjusted, so that the sunlight reflecting point is always positioned in the second light zone 102. After the sun falls down, the photovoltaic panel 1 does not receive the sunlight, and the deflection positions of the second reflecting plate 202 and the third reflecting plate 203 are adjusted to prepare for the reflection when the sun rises next time.

The third concrete embodiment: on the basis of the second embodiment, the number of the air pipes 304 for heating the group 301 is two, and the air pipes are divided into air pipes in the daytime and air pipes in the night. The positions of the air outlets of the air pipes at daytime and at night are opposite relative to the first fan blade 205, the first fan blade 205 rotates clockwise after the air pipes jet air in daytime, and the first fan blade 205 rotates anticlockwise to east after the air pipes jet air at night. The number of the electromagnetic valves 306 is two, and the two electromagnetic valves are divided into a daytime valve and a night valve, and the daytime valve and the night valve respectively correspond to a daytime air pipe and a night air pipe. The daytime valve is located in the white weather pipe. The night valve is positioned in the trachea. The daytime valve and the night valve are both electrically connected with the controller 5. The heating group 301 and the heating group 302 are the same components.

When the sun irradiates the reflection unit 2 in the daytime, the controller 5 controls the daytime valve to be intermittently opened, and the nighttime valve to be continuously closed, and the working mechanism of the daytime valve is the same as that of the electromagnetic valve 306 in the second embodiment.
