Description

Technical Field

[0001] The present application relates to the technical field of water ecological management, and in particular to an aeration and oxygenation device for managing the environment of green algae in rivers. Background Art

[0002] Green algae in the river channel will cause water hypoxia and kill animals. Decomposers consume oxygen during decomposition, causing a vicious cycle. Water with sufficient dissolved oxygen can promote the growth and reproduction of fish and beneficial bacteria, which will eat the green algae, prevent eutrophication of the water body, and reduce the reproduction rate of green algae. In rivers where green algae are rampant, aeration is usually used to increase oxygen and thus increase the oxygen content of the water. Aeration usually refers to the process of increasing the oxygen concentration in water through contact between water and air. In the field of water ecological environment governance, aeration is a phased measure mainly suitable for maintaining water quality. It has the function of reoxygenating water, which can effectively increase the dissolved oxygen level of local water bodies and increase regional water fluidity.

[0003] In the prior art, when aerating a river channel, an aeration device is often placed in the river channel. Although this can increase oxygen for the water in the river channel, it cannot remove the green algae, which still exists in the river channel. After aeration, the green algae will continue to consume oxygen in the water body. Therefore, it is necessary to manually salvage and clean the green algae in the river channel separately, which is very troublesome to operate. In addition, the operation in the river channel is easily affected by the outdoor weather, so the cleaning efficiency is low. In addition, the floating green algae floating on the water surface in the river channel often grows in sheets, which can easily block the collection channel when collected.

[0004] To this end, we propose an aeration and oxygenation device for river green algae environmental management to solve the above problems. Summary of the invention

[0016] Compared with the prior art, the advantages of this application are: (1) By setting up an aeration component, the motor is electrically connected to the power box, and the motor is started. The motor drives the paddle blade to rotate. The rotation of the paddle blade stirs the water, stirs up water splashes, stirs air into the water, and generates a force to press the surface water into the bottom, thereby achieving aeration and oxygenation.

When the device moves in the river channel, the filter screen filters the river water and filters the green algae. The scraper moves to scrape off the green algae filtered on the filter screen and pushes the scraped green algae to the collecting parts on both sides, thereby realizing the cleaning and collection of the green algae in the river channel while aerating and increasing oxygen.

[0018] (3) By setting up a cutting piece, the scraper moves while driving the cutter to move. When the cutter contacts the side wall of the filter, the scraper continues to move, the spring is compressed, and the cutter is squeezed under the action of the spring elastic force to cut the green algae into small pieces for easy collection, avoiding clogging of the through hole and the collecting piece.

[0019] (4) By setting a collecting part and a drainage part, the driving motor drives the second blade to rotate, and the rotation of the second blade drives the water in the L-shaped channel to flow from the second through hole toward the second blade, so that the green algae divided into small sections in the filter screen are sucked into the L-shaped channel through the first through hole and the second through hole and flow with the water flow. In the process of flowing, the water passes through the filter plate, and the filter plate intercepts the green algae in the water, so that the green algae automatically enters the collection net box for collection.

[0020] (5) The rotation of blade 2 can also generate thrust on the water, driving the water to flow backward, thereby pushing the device forward, assisting blade 1 in aeration and moving forward, making the oxygenation effect better and the driving force for the device to move forward stronger.

[0021] (6) By setting the filter plate at an angle, the water flow can not only intercept the green algae in the water when passing through the inclined filter plate, but also make the intercepted green algae move downward under the action of gravity and impact force, and fall into the collection net box below through the through hole three for collection.

[0022] (7) By setting a trumpet cover on the outside of the filter, the cleaning area can be expanded, making it easier to collect green algae. BRIEF DESCRIPTION OF THE DRAWINGS
