DEVICE FOR AERATION OF WATER BODIES ,PARTICULARLY, IN WINTER

摘要

The invention relates to fish farming, in particular, to devices for aerating fish-bearing reservoirs in winter, and can be used in aeration complexes installed on rivers and reservoirs. The purpose of the invention is to increase the efficiency of use. For this, the aeration device is equipped with a movable platform 5, a telescopic boom 6, perforated pipes (PT) 2, an air distributor 7, a turntable carriage 8 PT 2, a turn cable 9, upper and lower flexible links 10, 11, and a turn load 12. Through the winch 3 and the cable 4 PT 2 with the distributor 7 is lowered into the hole. When a certain depth of the reservoir is reached, the cable 9 thrown over the roller 14 is weakened, the turning carriage 8 connected to it is lowered, and the folded PT 2 under the influence of the load 12 of rotation is fanned out of the distributor 7 and take a horizontal position. Through the flexible pipeline connecting system 1 and distributor 7, compressed air flows through the PT 2 into the reservoir. The length of the PT2 is set manually, depending on the depth of the wintering we. 6 hp f-ly, 3 ill.
