Description
Technical field
The present invention relates to a kind of at the bottom of pond water improving machine based on independent navigation ship, belong at the bottom of pond water quality improvement technique neck
Domain.
Background technology
The principal mode of China's aquaculture is high density pond culture at present, and China's pond culture area accounts for total Aquatic product and supports
Grow more than the 52% of total amount, the high essential condition of cultivation density seeks to using substantial amounts of feedstuff and preparation, due to taking the photograph of feedstuff
Food rate is not high, and substantial portion of feedstuff is all deposited on pond bottom, the animals and plants corpse of generation and excretion in pond simultaneously
Feces also more, bigger pressure is caused to bed mud environment.The precipitation of these Organic substances decompose be need to consume substantial amounts of
Oxygen, the dissolved oxygen in pond has photosynthesis that most both is from plants in water, in the air be dissolved into water body
In oxygen only occupy small part, even if the illumination being subject to due at the bottom of pond on daytime is less, Organic substance decompose insufficient,
To night, due to not having photosynthesis, the Organic substance decomposition at the bottom of pond bed mud can consume a lot of dissolved oxygen, causes pond oxygen
Content is relatively low, threatening the product existence of Aquatic product, simultaneously because there is many harmful substances and pathogenic microorganism in bed mud, can lead
Nitrite, ammonia-nitrogen content is caused to raise, the premunition of Fish declines, and pathogenic microorganism etc. spreads in a large number, leads to fish
Sick breaks out.Improve pond culture condition it is important that be exactly some the condition improving bed mud, simultaneously from changing dissolved oxygen and consumption
Inhomogeneities on the room and time of pond for the oxygen are set about, and reduce night unnecessary oxygen consumption, reduce harmful substance in bed mud
Content.Solve problems to be accomplished by enabling bed mud to be adequately exposed to illumination in the case of daylight abundance, allow Organic substance
Fully decompose, bottom water body is promoted to simultaneously and utilizes photosynthesis abundant oxygen supplement to bottom water body at the middle and upper levels.
Also there is the water quality improvement device being specifically designed for sediment of pond in prior art, but, in actual use, pond
Bottom is often uneven, and the adaptivity ability between suction nozzle position and at the bottom of pond is poor, is susceptible to rigid collision, leads to water pump
Machine absorption bed mud is less efficient, and nozzle section bit loss is bad simultaneously；Additionally, the ability that existing water quality improvement device is walked on the water surface
More limit to, some dependence is realized moving by the straight walking mechanism that rope pulls, and have is self-powered, but power consumption is higher, OK
Walk inconvenience, lead to water quality improvement region to be limited to.
Content of the invention
In prior art be directed to sediment of pond water quality improvement device, in actual use, at the bottom of pond often concavo-convex not
