Solar heat collector cleaning device

The invention discloses a cleaning device for a solar heat collector. The cleaning device comprises a rolling driving type water draining control mechanism, a rolling water draining one-way rotating mechanism, a scraper wiping mechanism and a main body driving mechanism. The invention belongs to the technical field of heat collector cleaning, and particularly relates to a solar heat collector cleaning device. In order to solve the problem of how to adaptively control a drainage valve to be opened and closed, the rolling driving type drainage control mechanism is creatively provided according to the hydraulic structure principle, and through cooperation of a fixed inner gear ring and a rolling outer gear ring, the rolling outer gear ring is controlled to have the driving effect only when rotating in one direction; the sliding of the arc-shaped sliding valve clack is controlled through the stirring of the rolling sleeve on liquid, and the technical effect of self-adaptive control of a drainage switch is achieve
