Because the stress reaction of the fry can be caused by the traditional netting gear fishing, and the mechanical damage of the body surface of the fry can be caused by the direct contact of the fished netting gear and the fry body, the survival rate of the fry is seriously influenced. In this scheme, ripe fry can directly pass through fry collecting pipe 10 is collected, and whole process fry is direct not contact with people and fishing tool, has replaced the mode that traditional adoption netting gear caught, can collect the fry of hatching harmless ground, has improved the survival rate of fry.
Referring to fig. 2, the bottom of the cylinder 1 is further communicated with a vent pipe 11, and an air outlet end of the vent pipe 11 extends from the bottom of the cylinder 1 and is connected with a microporous aeration disc 111. Among the traditional means, for realizing high dissolved oxygen volume and avoiding the roe to sink to hatching barrel bottom and pile up, the main means of adoption is the oxygenation of washing by water, and this mode is not only that the water consumption is big, oxygenation is inefficient, can strike the roe that is about to the drawing of patterns moreover, influences the hatching of roe. In the scheme, the microporous aeration disc 111 can separate oxygen into nanoscale air flow and form nanoscale bubbles in water, the nanoscale bubbles have longer retention time in water, the utilization efficiency of oxygen is improved, and a good living environment is provided for roes and hatched fries.
The both ends of swivelling joint axle 3 all are connected with cleaning brush 4, two 4 symmetric connections of cleaning brush are in the both ends of swivelling joint axle 3 have improved the cleaning efficiency of solid filth. In this embodiment, the driving mechanism 8 is a micro motor, and the rotation speed of the micro motor can be adjusted according to requirements.
The cylinder body 1 comprises an upper half part and a lower half part, wherein the upper half part is in a shape of an inverted round table, and the lower half part is in a shape of an inverted triangular cone. The water outlet end of the water inlet pipe 9 or the inlet end of the fry collecting pipe 10 or the air outlet end of the air vent pipe 11 are communicated with the top of the bottom end of the cylinder body 1, so that disturbance of inflow water flow can be realized respectively, and roes and other solid dirt are prevented from being deposited on the bottom of the cylinder body 1; the hatched fry can be transferred without damage, and the fry is convenient to arrange; and micro-nano bubbles can be provided, the stay time of the bubbles in water is longer, the effective utilization rate of oxygen is greatly improved, and the fish egg sedimentation is also avoided because of accumulation of oxygen deficiency at the bottom of the cylinder body 1.
In the embodiment, the raw material of the cylinder 1 is Polyethylene (PE) or polypropylene (PP), the thickness of the cylinder is 8-12 mm, and the inner included angle of the lower half part of the inverted triangular cone shape of the cylinder 1 is 90-110 degrees; the support frame 2, the rotary connecting shaft 3 and the drainage collecting cylinder 6 are all made of PE or PP; the raw material of the cleaning brush 4 is nylon (PA) or PP; the aperture of the filtering and intercepting net 5 is 60-100 meshes, and the material is stainless steel or PA; the inner diameter of the drain pipe 7 is 32-50 mm; the weight of the micro motor is not more than 200g, and the power is not more than 15W; the inner diameters of the water inlet pipe 9 and the fry collecting pipe 10 are 25-40 mm, and the inner diameters of the water supply pipeline 91 and the fry collecting main pipe 101 are 40-65 mm; the size of the vent pipe 11 is 10-25 mm; the aeration surface of the microporous aeration disc 111 is spherical, the top view is circular, and the lowest distance between the aeration spherical surface and the periphery of the inner wall of the cylinder with the same horizontal section is not less than 20 mm.
The working principle is as follows:
the breed water in the water supply pipeline 91 passes through inlet tube 9 gets into barrel 1, and flow from bottom to top in the barrel 1, the in-process that flows, the solid filth in the breed water by filter interception net 5 is caught, and the adhesion is in filter interception net 5 is last, cleaning brush 4 is in under actuating mechanism 8's the drive, can realize 24h no dead angle, continuous washing filter interception net 5, avoid the solid filth in the breed water to block up filter interception net 5's mesh ensures filter interception net 5's mesh is unblocked constantly, avoids appearing the overflow and the seedling phenomenon that runs that leads to, has replaced current 24 hours of dependence manual work to clear up in succession, and labour saving and time saving can also avoid appearing and wash the dead angle, washs comparatively thoroughly, has improved the cleaning efficiency. The filtered water body enters the drainage collecting cylinder 6 and is finally discharged through the drainage pipe 7. Oxygen enters the cylinder body 1 after sequentially passing through the air pipe 11 and the micropore aeration disc 111. The nano-level bubbles have longer retention time in water, the effective utilization rate of oxygen is improved, good living environment of roes and incubated fries is facilitated, and by combining the water flow power transmitted by the water inlet pipe 9, the roes can be prevented from depositing to the bottom and dying due to accumulation of oxygen deficiency, the roes can roll up and down in the barrel body 1, the hatching rate of the roes is improved, and the energy consumption is reduced; after the fish eggs are hatched into fry, the fry can be transferred from the fry collecting pipe 10 without damage.
