[0023] The bottom ends of the two groups of support rods 2 are fixedly connected to a fixed base plate 201, and multiple groups of mounting holes 202 are provided inside the two groups of fixed base plates 201. Multiple groups of reinforcing plates 203 are fixedly connected between the two groups of fixed base plates 201 and the support rods 2. The support rods 2 are fixedly installed through the mounting holes 202 on the fixed base plate 201. After installation, the structural strength of the support rods 2 can be guaranteed by the connection of multiple groups of reinforcing plates 203, thereby ensuring the supporting strength of the bracket 1 after installation.

[0024] The adjusting mechanism 4 includes a casing 401 fixedly mounted on the top of the supporting rod 2, the casing 401 is internally rotatably connected to a worm gear 402, and the connecting shaft 3 is fixedly connected to the inside of the worm gear 402, the bottom end of the casing 401 is rotatably connected to a worm 403, and the worm 403 is meshed with the worm gear 402, and the worm gear 402 is driven to rotate by rotating the worm 403, thereby driving the bracket 1 to rotate through the connecting shaft 3, and then the reflection angle of the reflection plate 5 can be adjusted, and the reflection plate 5 is adjusted to the angle with the largest illumination range, so that the sunlight can directly irradiate the reflection plate 5 to the maximum extent, thereby greatly increasing the utilization rate of solar energy.

[0025] The front end of the worm 403 is fixedly connected to an adjusting crank 404, and the outer side of the adjusting crank 404 is fixedly connected to a fixed gear 405. A pull rod 406 is slidably connected to the top of the support rod 2 and located on the left side of the fixed gear 405.

After the adjustment is completed, release the pull rod 406, and fix the fixed tooth block 407 to the fixed gear 405 under the action of the spring 408, thereby ensuring the stability after adjustment.

[0026] A filter net 601 is fixedly installed on the top of the two groups of water collecting tanks 6, and a baffle 602 is slidably connected to the top of the opposite side of the two groups of water collecting tanks 6. When the self-concentrating all-glass solar collector is in use, rainwater can be guided and collected through the water guide plate 7 in rainy weather, and the rainwater is collected inside the water collecting tank 6. During the rainwater collection process, it is filtered through the filter net 601 to prevent impurities from entering the interior of the water collecting tank 6.

[0027] Water pumps 603 are fixedly installed on the right side of the two water collecting tanks 6. The input ends of the two water pumps 603 are connected to the inside of the water collecting tank 6 through the suction pipe 604, and the output ends of the two water pumps 603 are connected to the spray pipe 8 through the water supply pipe 605. As the self-concentrating all-glass solar collector is used for a long time in sunny weather, dust and impurities are easily collected on the reflector 5. At this time, the water pump 603 is started to pump out the rainwater collected in the water collecting tank 6 through the suction pipe 604, and then pump it into the spray pipe 8 through the water supply pipe 605.

[0029] Implementation scheme: The support rod 2 is fixedly installed through the mounting hole 202 on the fixed base plate 201, so as to fix the bracket 1, and the worm wheel 402 is driven to rotate by rotating the worm 403, so that the bracket 1 can be driven to rotate through the connecting shaft 3, and then the reflection angle of the reflector 5 can be adjusted, and the reflector 5 is adjusted to the angle with the largest illumination range, so that the sunlight can directly irradiate the reflector 5 to the maximum extent, which greatly increases the utilization rate of solar energy. After the adjustment is completed, the worm 403 can be fixed to ensure the stability after adjustment. When the self-concentrating all-glass solar collector is used, in rainy weather, the rainwater can be guided and collected by the water guide plate 7, and the rainwater is collected inside the water collection box 6. During the rainwater collection process, it is filtered through the filter net 601 to prevent impurities from entering the water collection box. 6, as the self-focusing all-glass solar collector is used for a long time in sunny weather, dust and impurities are easily collected on the reflector 5.

Water is sprayed out through the multiple groups of water spray heads 801 on the water spray pipe 8 to clean the surface of the reflector 5. The whole operation process is simple and convenient. Compared with the existing self-focusing all-glass solar collector, the utility model is designed to collect and utilize rainwater to clean the reflector 5, which not only does not cause wear to the surface of the reflector 5, but also does not require manual maintenance to clean the reflector 5, thereby ensuring the heat collection effect of the solar collector.
