Underwater swimming type jet oxygen-increasing machine

Abstract

The invention discloses an underwater swimming type jet oxygen-increasing machine. The underwater swimming type jet oxygen-increasing machine is characterized by comprising an underwater pump positioned below the water surface of a water body, a supporting plate for supporting the underwater pump, a positioning float bowl for adjusting the depth of the underwater pump, a positioning anchor for keeping the underwater pump at a selected position in the water body and a waterproof trailing cable with adjustable length for controlling an underwater swimming radius of the underwater pump. A middle opening of a three-way valve on the underwater pump is communicated with a water outlet of the underwater pump; the openings at both sides of the three-way valve on the underwater pump are respectively communicated with a sector diversion tube; the sector diversion tube is provided with a plurality of jet devices uniformly distributed along the radial direction; the jet devices are provided with air inlet tubes the openings of the upper end of which extend from the water surface; and the positioning anchor is positioned at the middle zone of the water body. The invention has the advantages of being capable of solving low energy oxygenation of anoxic water at the middle and bottom layers with a large scope, pushing the water body to do circular motion simultaneously, and generating downwelling and vertical convection so as to improve circulation of the water body and ecological restoration and realize pumping function.

Description

technical field [0001] The invention relates to an aerator, in particular to a submersible jet flow aerator. Background technique [0002] Aerator is a machine often used in fish farming and water body treatment. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic, and it can also inhibit the growth of anaerobic bacteria in the water. Prevent pool water from deteriorating and threatening the living environment of fish. At present, the aerators commonly used in international and domestic aquaculture and water environment protection include waterwheel type, rotary vane type, and water spray type. The purpose of increasing the oxygen content in the water, but it is difficult for the above various aerators to increase the oxygen to reach the bottom layer, so the efficiency of oxygenation for the anoxic bottom water body is not high. [0003] Although the existing jet-type aerator can increase oxygen at the b...

Problems solved by technology

At present, the aerators commonly used in international and domestic aquaculture and water environment protection include waterwheel type, rotary vane type, and water spray type. The purpose of oxygen content in water, but it is difficult for the above various aerators to increase oxygen to reach the bottom layer, so the efficiency of oxygen increase in the anoxic bottom water body is not high

[0003] Although the existing jet-type aerator can increase oxygen at the bottom layer, the range of influence of the jet flow is limited, and the oxygenation efficiency for the anoxic bottom water is not high. To expand the oxygen-increasing range of the jet flow, it is necessary to increase the power and energy consumption
