The oxygen supply feeding mechanism has the following principle:

oxygen supply: because of the existence of the floating plate, the food box is normally positioned above sea level, the height of local water surface can be changed under the push of sea waves, so that the floating plate is sometimes positioned at the connection part of the sea level and sometimes positioned below the sea level, and further the corrugated pipe is in a frequent pulled state, in the process that the lower end of the corrugated pipe is stretched, outside air can enter the food box through the vent hole and enter the corrugated pipe, but cannot enter the bottom of the net box due to higher required pressure, when the corrugated pipe is contracted due to the existence of the reset spring, the air cannot be discharged through the vent hole due to the existence of the one-way valve, and further passes through the hose, the upright post, and then enters the bottom box, enters the bottom of the net box from the air outlet hole in the middle of the bottom box, and oxygen is;

feeding: powdered or granular fish food of path loads in the food case, can send into some food in the bottom box at the in-process that the air got into the bellows by the air vent to get into in the box with a net by the venthole.

The blocking of the inlet of the one-way valve may be caused by powdery or small-diameter granular fish food, the smooth entering of air into the inlet of the one-way valve may also be affected, if seawater enters the food box due to the overlarge inclination degree of the food box caused by sea waves and other reasons, the serious consequence of the caking of the fish food may be caused, thereby further causing the blocking of the inlet of the one-way valve and the blocking of the hose, in order to realize the ventilation of the food box without water intake, and to stir the fish food in the food box, especially to dredge the inlet of the one-way valve, two check rods are symmetrically arranged in the food box, since the inner end of the vent pipe is upward, outside rainfall and rainfall can not enter the food box, the check rods are moved outwards due to the weight to form an air inlet channel between the outer wall of the check rod and the inner wall of the vent hole, air can enter, if the food box is inclined, the seawater may enter the, buoyancy forces the check rod to move up, and the check rod moves to the food box in promptly, makes the inlet channel who forms between check rod and the air vent closed, because the effect of pinion rack and screw rod can cause the longitudinal movement and the rotation of pay-off pole at the in-process that the check rod removed, specifically: when the check rod moves towards the inner side of the food box, the feeding rod moves upwards and rotates, when the check rod moves towards the outer side of the food box, the feeding rod moves downwards and rotates, and the toothed plate is fixedly connected to the two check rods, so that the moving directions of the two check rods are opposite, the check rods moving inwards can be the check rods in the inclined direction of the food box, the air vent on one side of the inclined food box is blocked, and the air vent on the other side is in a smooth state.

And a plurality of groups of check rods can be arranged to be uniformly distributed outside the food box, so that the waterproof effect is improved.

The in-process that the check rod removed in the air vent, pinion rack meeting lateral shifting, the reed offsets the longitudinal movement trend of pinion rack, and the in-process of feed lever longitudinal shifting can reset because of the existence of extension spring, and the removal of feed lever, reed and check rod can make the air admission passageway that the air admission check valve entry be in unobstructed state, and can avoid the condition that the fish food forms "cavity" or food is difficult to get into the bellows at the check valve entry.

The scheme can be realized in water areas with high and low fluctuation on the water surface, such as reservoirs (the water areas with larger areas also have horizontal plane fluctuation caused by wind), sea areas, lakes and the like.

Because the top of the net cage is not connected with the sea surface, oxygen required by high-density cultivation is insufficient to a certain extent, the feeding difficulty of food is greatly increased, and an oxygen supply feeding mechanism is arranged.

The oxygen supply feeding mechanism has the following principle:

oxygen supply: because of the existence of the floating plate 24, the food box 25 is normally positioned above sea level, the local water level height can be changed under the push of sea waves, so that the floating plate 24 is sometimes positioned at the connection position of the sea level and sometimes positioned below the sea level, and further the corrugated pipe 21 is in a frequent pulled state, in the process that the lower end of the corrugated pipe 21 is stretched, outside air can enter the food box 25 through the vent hole 28 and enter the corrugated pipe 21, but cannot enter the bottom of the net box due to higher required pressure, and when the corrugated pipe 21 is contracted due to the existence of the return spring 27, the air cannot be discharged through the vent hole 28 due to the existence of the one-way valve, further passes through the hose 23 and the upright post 13, then enters the bottom box 11, enters the bottom of the net box from the air outlet hole 29 in the middle of the bottom box 11, and oxygen is supplied by blowing at the;

feeding: powdered or small-diameter granular fish food is loaded in the food box 25, and part of the food can be fed into the bottom box 11 in the process that air enters the corrugated pipe 21 through the vent hole 28, so that the food enters the net box through the vent hole 29.

Because powdery or small-diameter granular fish food can cause the blockage of the inlet of the one-way valve and can also influence the smooth entering of air into the inlet of the one-way valve, if seawater enters the food box 25 due to the overlarge inclination degree of the food box 25 caused by sea waves and other reasons, the serious consequence of the caking of the fish food can be caused, thereby further causing the blockage of the inlet of the one-way valve and the blockage of the hose 23, in order to realize the ventilation of the food box 25 without water entering, and can stir the fish food in the food box 25, in particular to dredge the inlet of the one-way valve, two check rods 32 are symmetrically arranged in the food box 25, because the inner end of the vent pipe 31 is upward, outside water and rainfall can not enter the food box 25, the check rods 32 are weighted and move outwards to form an air inlet channel between the outer walls of the check rods 32 and the inner walls of the vent holes 28, air can enter, if the food box 25 is inclined, the seawater can, the floating ball 39 first contacts the sea water, the buoyancy drives the check rod 32 to move upwards, i.e. the check rod 32 moves towards the food box 25, so that the air inlet channel formed between the check rod 32 and the vent hole 28 is closed, and due to the action of the toothed plate 34 and the screw 37, the longitudinal movement and rotation of the feeding rod 35 are caused during the movement of the check rod 32, specifically: when the check rod 32 moves towards the inner side of the food box 25, the feeding rod 35 moves upwards and rotates, when the check rod 32 moves towards the outer side of the food box 25, the feeding rod 35 moves downwards and rotates, and because the toothed plate 34 is fixedly connected to the two check rods 32, the moving directions of the two check rods 32 are opposite, the check rods 32 moving inwards can be the check rods 32 in the inclined direction of the food box 25, so that the vent holes 28 on the inclined side of the food box 25 are blocked, and the vent holes 28 on the other side are in a smooth state.

A plurality of sets of check rods 32 can also be arranged to be evenly distributed outside the food box 25, thereby improving the waterproof effect.

In the process that check rod 32 moves in vent hole 28, toothed plate 34 can lateral shifting, and the longitudinal movement trend of toothed plate 34 is offset by reed 33, and the in-process of feed rod 35 longitudinal movement can reset because of the existence of extension spring 36, and the removal of feed rod 35, reed 33 and check rod 32 can make the air inlet channel that air got into the inlet of check valve 26 be in unobstructed state, and can avoid the condition that the fish food forms "cavity" or food is difficult to get into bellows 21 at the inlet of check valve 26.
