Solar sludge plowing movable aeration device

Abstract

The invention relates to a solar sludge plowing movable aeration device. When the device runs and air enters an air inlet, the air enters an annular floating body through a floating hollow cross rod,the floating body floats upwards, a chain is driven to rise upwards between chain link pin rollers of opening popup chains of a shifting fork until the cross rod of the floating body touches the upperlimit component, an upper limit component commands a solenoid valve to open, the air in the floating body is released and discharged, the floating body drives the shifting fork to simultaneously sink, the shifting fork rebounds, slides out and falls under the action of spring force, a lower limit component commands the solenoid valve to close when the floating body sinks until the cross rod touches the lower limit component, the air is collected in an annular box of the floating body, and the floating body floats upwards and returns to the state. When the floating body drives the chain, the chain transmits force to a lower chain wheel, the lower chain wheel drives a worm shaft, the worm shaft drives a hanging worm wheel seat, the hanging worm wheel seat drives a crawling shaft and a screwcrawling head, and the solar movable sludge plowing aeration device can crawl and move in sludge.

Description

Technical field [0001] The invention relates to a device for turning and exchanging bottom water and upper water of a pond, in particular to a solar-powered silt plowing mobile aeration device. Background technique [0002] China is a big country in the cultivation of aquatic products in ponds, but the sediment of fish manure residues is the biggest problem in farming, and it is also the biggest headache for farmers. The oxygen content monitoring of the water quality of the aquaculture ponds for 24 hours found that the oxygen content of the water layer between 0.5 and 1.5 meters was 6.3 mg / L, while the oxygen content of the water layer below 0.5 meters was only 0.8 mg / L, indicating the residual bait in the pond culture. The excrement is deposited on the bottom layer, and when the organic matter is not fully oxidized by oxygen, the sediment will undergo anaerobic fermentation and release a large amount of organic matter, NH 3 And H 2 S and other harmful substances dissolve in the ...

Problems solved by technology

The 24-hour monitoring of the oxygen content of the water quality in the aquaculture pond found that the oxygen content of the water layer between 0.5-1.5 meters was 6.3mg / L, while the oxygen content of the water layer below 0.5 meters was only 0.8mg / L, which shows that the residual bait in the pond culture The excrement settles on the bottom layer, and when the organic matter does not get enough oxygen to oxidize, the sediment undergoes anaerobic fermentation and releases a large amount of organic matter and NH 3 and H 2 Harmful substances such as S are dissolved in the bottom water to make the oxygen content ultra-low, which deteriorates the water quality and causes diseases of aquaculture products, affecting the quality and output of aquaculture products.

At present, suction dredging is used or dry pond dredging after two or three years, which wastes a lot of manpower and material resources
