This application relates to the technical field of smart water management, and in particular to a smart water management energy-saving and water-saving control device, including a downpipe and a blade adjustment device. This solution uses an arc-shaped guide plate, with its concave surface facing the direction of water flow and its convex surface facing the impeller. This causes the water to flow along the arc-shaped surface during its descent, changing the water's trajectory and converging the dispersed water flow to guide it to the blades of the impeller. This enhances the impact force of the water flow on the impeller, improving energy conversion efficiency. The excess potential energy of the water flow is converted into electrical energy for utilization. Simultaneously, the rotating shaft drives gear two to rotate, gear two drives gear one to rotate, and gear one adjusts the angle of attack between the rotating shaft one and the impeller blades. At high flow rates, the angle of attack is reduced to avoid impeller overload, while at low flow rates, the angle of attack is increased to fully capture water flow energy, maintaining high energy conversion efficiency at both high and low flow rates.

The present invention introduces a portable gutter and downspout cleaning device for use with leaf blowers, featuring a blower nozzle with a rotatable elbow, flat plastic tubing, and a gutter cleaning nozzle with an extension pole socket. The tubing length is customizable for various gutter heights and accessibilities, and fastening components ensure airtight connections between the tubing and nozzles, transforming the tubing into an extended air conduit. For downspout cleaning, air pressure from the blower inflates the tubing within the downspout, using the downspout as an extended air conduit to facilitate debris removal. The rotatable connection incorporates tiered outer teeth and internal grooves with cross-channels, enabling secure assembly and rotational movement. A locking mechanism restricts the teeth from passing through the cross-channels, preventing unintended disconnection. This invention offers a cost-effective, adaptable solution for cleaning both gutters and downspouts safely from ground level, significantly reducing the risks associated with ladder-related injuries.
