Photovoltaic power supply water heating device for travel trailer

The invention discloses a photovoltaic power supply water heating device for a travel trailer, and relates to the technical field of photovoltaic power supply water heating devices. The solar panel assembly is convenient to clean. The cleaning device specifically comprises a solar panel assembly, a mounting frame and a base, the solar panel assembly is mounted on the mounting frame, the mounting frame is mounted on the base, the base is mounted on the top of the motor home, and a cleaning mechanism is arranged on one side of the mounting frame and comprises a water storage tank and a water collecting hopper. By arranging the water collecting hopper, the water storage tank and other structures, rainwater can be collected and stored in the water storage tank, and the hollow floating rod floats upwards based on the buoyancy of the air bag floater, so that the linear distance from one end of the flushing pipe to the hollow floating rod is increased, and the effect that the flushing pipe extends to the top of the
