Description

At the bottom of bionic movement formula marine culture pond, chlorination equipment is received in dirt
Technical field
The utility model relates to marine culture technical field, particularly relates to dirt at the bottom of a kind of bionic movement formula marine culture pond and receives chlorination equipment.
Background technology
In recent years, mariculture industry development in China's Coastal Areas is very fast.Batch production seawater high-density intensive culture, while obtaining distinct economic, also faces some health, safe cultivation problems, such as dirty queueing problem at the bottom of high-density breeding pond.The end dirt of culturing pool comes autotomy bait, excreta, biological corpse etc. usually, for preventing germ from growing infection, needs regularly to remove.Although be generally all provided with sewage draining exit in center, pond in the tectonic sieving of existing industrial aquaculture pond, but rely on culturing pool force of circulation also cannot all sweep away residue in water, Certain residues will be deposited in bottom culturing pool, easily grows germ, forms health hazard to aquaculture organism.
At present, the existing design some patents disclosing part sewage suction device.Such as, patent " electric sewage suction device for factory farming ", the patent No. 201010264506. 5, discloses a kind of two electronic sewage suction device of rotating disk; Patent " Industrialized culture energy-saving filth suction device ", the patent No. 201010264511.6, discloses a kind of method that roller bearing siphon is removed contamination.These patented methods all employ siphon principle by dirty for end suction to outside culturing pool, have certain energy-saving effect.But from actual effect, still there are following some shortcomings in these patented methods: one is device by dirty for end suction to outside pond, need socket blowdown flexible pipe, when sewage suction device moves back and forth, this root blowdown flexible pipe also moves around in water, constantly stir water body, the normal activity rule of aquaculture organism certainly will be disturbed; Two is siphon blowdown methods the end of by, dirt is removed while, and also siphoned away the part culturing pool water yield, because culturing pool is from the clean unit in aquaculture water circulating treating system, the loss of culturing pool certainly will increase the weight of live load and the purification drug consumption of clean unit; Three is that some germs are easily grown in dirt at the bottom of culturing pool, has potential hazard to aquaculture organism, and the now conventional water surface sprays the method for the pre-disease prevention of liquid medicine, does not consider that germ is uneven in spatial distribution, especially in the situation that end pollution layer is easily multiplied.Therefore, the problem that culturing pool blowdown apparatus is necessary to consider water saving, sterilize to emphasis at the bottom of biotic influence and pond is designed.
Have many fish builds special in marine organisms, parade action is light and handy.Such as, ray, is commonly called as " devil fish ", and build is partially flat roomy, is good at row of crawling, is not easily discovered by other biology; Fish mouth is roomy, is beneficial to and engulfs food.These biological characteristics have well enlightenment and reference function to improvement culturing pool sewage suction device.
Summary of the invention
For existing marine culture pond sewage suction device water saving, to biotic influence and the problem such as end dirt sterilization is not enough, the utility model provides dirt at the bottom of a kind of bionic movement formula marine culture pond to receive chlorination equipment.
Technical scheme described in the utility model is: at the bottom of bionic movement formula marine culture pond, chlorination equipment is received in dirt, it is characterized in that, is made up of the shell of imitative ray build, electric pump sewage sucking system, draining ahead running system, electronic control system four part; Described shell by main ring, vaulted top cover, soil pick-up side panel, receive dirty chassis and sewage disposal brush and form, described vaulted top cover and described main ring side interlock, described soil pick-up side panel is bowl-shape, the rim of a bowl side and described main ring opposite side interlock, bowl side, the end and described dirty chassis of receiving interlock, and described soil pick-up side panel has multiple soil pick-up notch, and each soil pick-up notch is wide flat, inside have some parting beads, described sewage disposal brush is arranged in described dirty chassis outer surface of receiving; Described electric pump sewage sucking system is made up of soil pick-up inner disc, screen pack, soil pick-up flexible pipe, electric pump and mozzle, described screen pack is arranged on inside the central water outlet mouth of described soil pick-up inner disc, the water inlet of described electric pump is connected by described soil pick-up flexible pipe with the central water outlet mouth of described soil pick-up inner disc, and the delivery port of described electric pump is connected with described mozzle; Described draining ahead running system is made up of six admittance stream joints, diaphragm valve, four-way jet flow joint and jet pipe, the water inlet of six described admittance stream joints is connected with described mozzle, the delivery port that water inlet and the six described admittance streams of described diaphragm valve save is connected, the water inlet that delivery port and the described four-way jet flow of described diaphragm valve save is connected, and the delivery port that described jet pipe and described four-way jet flow save is connected; Described electronic control system forms by touching switch, master switch, on-off logic device and internal battery, described touching switch is connected with described on-off logic device input port, the delivery outlet of described on-off logic device is connected with the power end of described diaphragm valve, and described master switch is connected between described internal battery and other electronic device.
Further, described soil pick-up inner disc flare, horn mouth side is connected with inside described shell soil pick-up side panel the rim of a bowl downwards, and center osculum is upwards connected with the water inlet of described electric pump by described soil pick-up flexible pipe.
Further, the through hole that six described admittance streams save relative two sides is cylindrical, and each through hole has joint to pacify to connect flexible pipe, also can screw and continues to employ with closing joint.
Further, described four-way jet flow joint is go out connectivity structure into three, and each joint all can be pacified and connect flexible pipe, also can screw and continues to employ with closing joint.
Further, this device is powered by described internal battery, and described electric pump is direct current generator.
Further, described on-off logic device realizes connection between constrained input port or opening operation according to arranging of logical table.
