<p>PURPOSE:To keep water quality stably at good condition by suspending an overflow weir connected with a downward flow guiding cylinder on the water surface and sending the water flowed over the weir by the effect of waves to the depth of the water area by the head without using mechanical power through said guiding cylinder to cause natural circulation. CONSTITUTION:An overflow weir 2 connected with a downward flow guiding cylinder 3 is suspended on the surface 1 of water, and the water overflowed the overflow weir 2 by the effect of waves is sent to the depth of the water area by the head without using power through the guiding cylinder to cause thus natural circulation. Thus, surface water contg. large amt. of oxygen can be naturally circulated utilizing wave energy without utilizing mechanical power to the depth of a water area, and the quality of water is stably kept in good condition economically with a simple constitution. The device is suited to the improvement of water quality of closed water area such as lake, storing reservoir, fishpond, etc.</p> |
