Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The first embodiment is such as shown in Figure 1, is the cleaning device of the solar water heater heat collector that adopts vacuum tube, comprises: water spray hole 1, endless crawler belt 2, the flexible scraper 3 as the first decontamination device, support 4, Water pipe 5, motor 6, hard scraper 7 and vacuum pipe 8 as the second decontamination device.

Wherein, two ring-shaped crawlers 2 are arranged on both sides of the solar vacuum tube 8 and are parallel to the vacuum tube 8, and the motor 6 drives one of the ring-shaped crawlers 2, and the other is follow-up. The support 4 straddles each vacuum tube 8 and is fixedly connected to the annular crawlers 2 on both sides, and the support 4 is detachably installed with a soft scraper 3 corresponding to each vacuum tube 8 . A hard scraper 7 parallel to the soft scraper 3 is arranged at the bottom of the solar water heater, and can be in contact with the side of the soft scraper 3 away from the support 4 . A water pipe 5 is arranged above the top of the vacuum pipe 8, and a water spray hole 1 is arranged corresponding to each vacuum pipe 8 on it.

When cleaning the heat collector of the solar water heater, the motor 6 drives the ring-shaped crawler 2 to keep rotating in one direction, and drives the soft scraper 3 on the support 4 on the ring-shaped crawler 2 to slide from top to bottom along the outer surface of the solar vacuum tube 8 to scrape off the deposits Dirt on the outer surface of the vacuum tube 8. When the soft scraper 3 moves to the bottom, the soft scraper 3 will turn upwards with the continuous rotation of the annular crawler belt 2. When turning over, the side of the soft scraper 3 away from the bracket 4 just touches the hard scraper set here. 7, the dirt on the soft scraper 3 is scraped off by the hard scraper 7, and the hard scraper 7 will not hinder the soft scraper 3 from continuing to move; after that, the soft scraper 3 continues to move from bottom to top with the rotation of the track Move, when reaching the top, the soft scraper 3 turns down with the rotation of the endless crawler belt 2, and continues to remove the dirt from top to bottom, so it is cleaned repeatedly.
