Compared with the prior art, the aquaculture net cage has the following advantages:
1. when the aquaculture net cage is used for aquaculture of fish, each bait recovery barrel is sunk in seawater through the rod and the anchor, and the aquaculture net cage floats in the seawater. Under the action of tidal energy and wave energy, the aquaculture net cage floats up and down, and each bait recovery barrel is kept static relative to the aquaculture net cage. Because the aquaculture net cages float up and down, the height positions of the aquaculture net cages in seawater are changed continuously, so that the mobility of water in the aquaculture net cages is greatly increased, pollution generated in the aquaculture net cages can be discharged in time, and the disease occurrence probability in the fish aquaculture process is reduced.
2. When the lower side cavity is enlarged, the lower piston sucks air on the sea surface into the lower side cavity through the air inlet one-way valve and the air inlet pipe in sequence; when the lower cavity is contracted, the lower piston discharges the air in the lower cavity into the aquaculture net cage through the exhaust pipe and the exhaust one-way valve in sequence, so that the oxygen content of the water in the aquaculture net cage is increased.
3. When the middle cavity is expanded, the bait in the bait collecting plate is sucked into the middle cavity through the bait suction one-way valve and the bait suction pipe in sequence by the suction force generated by the upper piston and the lower piston. In this process, as the bait collecting plate is located at a position lower than the lowest position of the intermediate chamber, the bait located in the bait collecting plate is also subjected to the pressure of the seawater, which enables the bait to effectively enter the intermediate chamber. When the middle cavity shrinks, the bait in the middle cavity is discharged into the cultivation net cage through the bait discharge pipe and the bait discharge one-way valve by the extrusion generated by the upper piston and the lower piston. In the process, because the water pressure in the middle cavity is equivalent to the water pressure at the position of the bait collecting plate, the water pressure in the middle cavity is greater than the water pressure on the bait discharging one-way valve, and the bait is effectively discharged from the middle cavity under the action of the pressure difference. Above-mentioned process realizes bait recovery and recycles, reduces bait extravagant, reduces the influence to marine geological environment.
4. The aquaculture net cage utilizes tidal energy and wave energy, realizes automatic water changing, oxygen supply and bait recycling and reutilization of the aquaculture net cage, effectively reduces pollution generated in the fish aquaculture process on the one hand, protects the environment, realizes reutilization of green resources such as tidal energy and the like, effectively reduces aquaculture cost on the other hand, and also improves aquaculture efficiency of fish aquaculture simultaneously.
5. The possibility of the bait being consumed is reduced by the fact that the bait becomes so agglomerated that it is too bulky or so dense that it is difficult for the fish to digest it after consumption. The crushing gear is driven by the transmission gear to rotate, and the crushing gear and the transmission gear rotate simultaneously, so that the bait in the middle cavity is crushed and refined, the fish can eat the bait effectively, and the utilization rate of the bait is improved.
6. In the middle cavity expanding process, the water pressure in the middle cavity is equivalent to the water pressure at the position of the bait collecting plate, and the structure is favorable for discharging the air in the lower cavity into the breeding net cage. And the exhaust check valve at the lower position is favorable for the air to contact with the water component in the cultivation net cage, so that the oxygen content of the water is effectively increased. On one hand, the bait discharging one-way valve at the higher position generates larger pressure difference by seawater, which is beneficial to the bait to enter and discharge from the middle cavity; on the other hand, the travel and the time of the bait falling to the bottom of the aquaculture net cage are increased, and the probability of the bait eating by the fish is effectively improved.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
The first embodiment is as follows:
referring to fig. 1 to 5, an aquaculture net cage with automatic oxygen supply and water change comprises an aquaculture net cage 1 floating in the sea, wherein the aquaculture net cage 1 comprises an upper support floating frame and a lower support frame, and further comprises:
each bait recycling cylinder 3 is vertically arranged and is connected between the upper supporting floating frame and the lower supporting frame in a sliding manner, and each bait recycling cylinder 3 is connected with an anchor 23 through a rod; the bait recycling cylinder 3 is coaxially arranged and is connected with an upper piston 31 in a sliding manner; a piston rod 311 is coaxially and fixedly arranged on the upper piston 31, the upper end of the piston rod 311 extends out of the bait recovery cylinder 3, and the end part of the piston rod is connected with the upper support floating frame; the bait recycling cylinder 3 is provided with an air inlet pipe 351 and an air outlet pipe 353; one end of each of the air inlet pipe 351 and the air outlet pipe 353 extends into a cavity which is formed by dividing the interior of the bait recycling cylinder 3 by the upper piston 31; the other end of the air inlet pipe 351 extends out of the sea surface, and an air inlet check valve 352 is fixedly arranged at the end part of the air inlet pipe; the other end of the exhaust pipe 353 extends into the aquaculture net cage 1, and the end part of the exhaust pipe is provided with an exhaust one-way valve 354.
Further, the number of the bait recycling barrels 3 is 4-8. Preferably, with reference to fig. 2, the number of bait recycling cartridges 3 is 4.
When the aquaculture net cage is used for aquaculture of fish, each bait recovery barrel 3 is sunk in seawater through the rod and the anchor 23, and the aquaculture net cage 1 floats in the seawater. Under the action of tidal energy and wave energy, the aquaculture net cage 1 floats up and down, and each bait recycling barrel 3 is kept static relative to the aquaculture net cage 1. Because the aquaculture net cage 1 floats up and down, the height position of the aquaculture net cage 1 in seawater is changed continuously, so that the mobility of water in the aquaculture net cage 1 is greatly increased, the pollution generated in the aquaculture net cage 1 can be discharged in time, and the disease occurrence probability in the fish aquaculture process is reduced.
In the process of floating the aquaculture net cage 1 up and down, the upper support floating frame drives the piston rod 311 to move up and down. The piston rod 311 causes the upper piston 31 to slide up and down. The chamber partitioned by the upper piston 31 inside the bait recovery cylinder 3 is changed between expansion and contraction. When the chamber including the inlet pipe 351 and the exhaust pipe 353 is changed between expansion and contraction, air outside the seawater enters the aquaculture net cage 1 through the inlet check valve 352, the inlet pipe 351, the exhaust pipe 353 and the exhaust check valve 354 in sequence, so that the oxygen content in the aquaculture net cage 1 is increased.
The aquaculture net cage takes tidal energy and wave energy as energy sources, so that the aquaculture net cage 1 can effectively and automatically change water, and the aquaculture net cage 1 drives a plurality of bait recovery cylinders 3 to simultaneously absorb air and increase oxygen content of seawater in the aquaculture net cage 1. The process makes full use of tidal energy and wave energy, and is green, environment-friendly and pollution-free.
Referring to fig. 1 and 2, further, an upper supporting floating frame and a lower supporting frame are respectively formed by connecting a plurality of connecting columns 11 end to end in sequence, and the upper supporting floating frame and the lower supporting frame are fixedly connected through a plurality of upright posts 12 which are vertically arranged; each upright post 12 is slidably provided with a sliding sleeve 21 and two limiting blocks 22 which are positioned in the vertical direction of the sliding sleeve 21; each bait recycling cylinder 3 is fixedly provided with a fixed seat 24; each fixed seat 24 is fixedly connected with two adjacent sliding sleeves 21.
When the aquaculture net cage 1 floats up and down, each bait recovery barrel 3 is static relative to the aquaculture net cage 1 under the action of the anchor 23, and each sliding sleeve 21 slides up and down on the upright post 12 corresponding to the sliding sleeve 21.
Referring to fig. 1, preferably, a plurality of fixed plates 111 with the same number as the bait recycling cylinders 3 are arranged on the upper support floating frame, and each fixed plate 111 is positioned right above one bait recycling cylinder 3; each fixing plate 111 is movably connected with the upper end of a piston rod 311.
When the aquaculture net cage 1 floats up and down, the aquaculture net cage 1 drives the piston rod 311 to move up and down through the fixed plate 111.
Referring to fig. 1 and 3 to 5, in particular, a lower piston 32 is also coaxially arranged and slidably connected in the bait recycling cylinder 3, and the lower piston 32 is positioned below the upper piston 31; the upper piston 31 and the lower piston 32 divide the interior of the bait recycling cylinder 3 into an upper side cavity 33, a middle cavity 34 and a lower side cavity 35 from top to bottom in sequence; a transmission mechanism is arranged between the upper piston 31 and the lower piston 32, and when the upper piston 31 slides up and down, the transmission mechanism drives the lower piston 32 to synchronously and reversely slide; one ends of the intake pipe 351 and the exhaust pipe 353 both extend into the lower chamber 35, and the ends of the intake pipe 351 and the exhaust pipe 353 extending into the lower chamber 35 are always located below the lower piston 32.
When the aquaculture net cage 1 drives the piston rod 311 to move up and down, the piston rod 311 drives the upper piston 31 to slide up and down, and the upper piston 31 drives the lower piston 32 to synchronously slide in the opposite direction through the transmission mechanism, so that the lower cavity 35 is changed between expansion and contraction. When the lower cavity 35 is expanded, the lower piston 32 sucks air on the sea surface into the lower cavity 35 through the air inlet check valve 352 and the air inlet pipe 351 in sequence; when the lower cavity 35 shrinks, the lower piston 32 discharges the air in the lower cavity 35 into the aquaculture net cage 1 through the exhaust pipe 353 and the exhaust check valve 354 in sequence, so as to increase the oxygen content of the water in the aquaculture net cage 1.
Referring to fig. 1 and 3 to 5, in detail, the bait recycling bin 3 is further provided with a bait suction pipe 36 and a bait discharge pipe 341; one end of the bait suction pipe 36 extends into the middle cavity 34, the other end extends into the bait collecting plate 4 arranged at the bottom of the aquaculture net cage 1, and the end part is provided with a bait suction one-way valve 366; the bait collecting plate 4 is in a round table shape with a large upper part and a small lower part; one end of the bait discharge pipe 341 extends into the middle cavity 34, the other end extends into the aquaculture net cage 1, and the end part is provided with a bait discharge one-way valve 342; the ends of the bait suction pipe 36 and the bait discharge pipe 341 extending into the middle chamber 34 are always positioned between the upper piston 31 and the lower piston 32.
In the culture process, because the bait is directly thrown into the culture net cage 1, a large amount of bait is not eaten by the fishes in the culture net cage and sinks into the bait collecting plate 4.
When the aquaculture net cage 1 drives the piston rod 311 to move up and down, the piston rod 311 drives the upper piston 31 to slide up and down, and the upper piston 31 drives the lower piston 32 to synchronously slide in the reverse direction through the transmission mechanism. That is, when the upper piston 31 moves upward, the lower piston 32 moves downward, and the middle chamber 34 expands while the upper chamber 34 and the lower chamber 35 contract at the same time; when the upper piston 31 moves downward, the lower piston moves upward, and the middle chamber 34 is contracted while the upper chamber 34 and the lower chamber 35 are simultaneously expanded.
As the intermediate chamber 34 expands, the suction created by the upper piston 31 and the lower piston 32 draws bait located in the bait collecting plate 4 into the intermediate chamber 34, through the bait suction check valve 366 and the bait suction tube 36 in sequence. During this process, the bait located in the bait collecting plate 4 is also subjected to seawater pressure, which makes the bait effectively enter the intermediate chamber 34, since the bait collecting plate 4 is located lower than the lowest position of the intermediate chamber 34.
When the middle chamber 34 is contracted, the bait located in the middle chamber 34 is discharged into the cultivation net cage 1 through the bait discharge pipe 341 and the bait discharge check valve 342 in order by the compression generated by the upper piston 31 and the lower piston 32. In this process, since the water pressure in the intermediate chamber 34 is equivalent to the water pressure at the position of the bait collecting plate 4, the water pressure in the intermediate chamber 34 is greater than the water pressure to which the bait discharging check valve 342 is subjected, and the bait is effectively discharged from the intermediate chamber 34 by this pressure difference.
Above-mentioned process realizes bait recovery and recycles, reduces bait extravagant, reduces the influence to marine geological environment.
This aquaculture net case utilizes tidal energy and wave energy, realizes aquaculture net case 1 simultaneously and trades water, oxygen suppliment and bait recovery and recycle automatically, effectively reduces the pollution that the fish culture in-process produced on the one hand, and the environmental protection realizes green resources such as tidal energy and recycles, and on the other hand effectively reduces the breed cost, still improves the breed efficiency that the fish was bred simultaneously.
Referring to fig. 1, in particular, the exhaust check valve 354 is positioned lower than the bait discharge check valve 342.
During the enlargement of the middle chamber 34, the water pressure in the middle chamber 34 is equivalent to the water pressure at the position of the bait collecting plate 4, and the structure is helpful for discharging the air in the lower chamber 35 to the aquaculture net cage 1. The exhaust one-way valve 354 at the lower position is beneficial to the contact of air and water components in the aquaculture net cage 1, and the oxygen content of water is effectively increased.
The higher bait discharge check valve 342, on the one hand, creates a larger pressure differential from the seawater to help the bait enter and exit the intermediate chamber 34; on the other hand, the travel and the time for the bait to fall to the bottom of the aquaculture net cage 1 are increased, and the probability of the bait for the fish is effectively improved.
Referring to fig. 1, in detail, the bait suction pipe 36 includes a fifth suction pipe 365 made of a rigid material, the fifth suction pipe 365 is vertically and fixedly installed on the lower piston 32, the upper end of the fifth suction pipe 365 passes through the lower piston 32 and the end thereof extends into the middle chamber 34, the lower end of the fifth suction pipe 365 extends into the lower chamber 35 and the end thereof is connected with a fourth suction pipe 364 made of a flexible material; the lower end of the fourth suction pipe 364 is positioned in the lower cavity 35 and the end of the fourth suction pipe 364 is connected with a third suction pipe 363 made of rigid material, the lower end of the third suction pipe 363 extends out of the lower end of the bait recycling cylinder 3 and the end of the third suction pipe 363 is connected with a second suction pipe 362 made of flexible material, and the lower end of the second suction pipe 362 is connected with a first suction pipe 361; the lower end of the first suction pipe 361 extends into the bait collecting plate 4, and the end part of the first suction pipe is connected with the bait suction one-way valve 366.
In the up-and-down floating of the aquaculture net cage 1, the second suction pipe 362 and the third suction pipe 363 move up and down along with the up-and-down floating of the aquaculture net cage 1. The lower piston 32 slides up and down to drive the fifth suction pipe 365 to stretch and compress the fourth suction pipe 364. This arrangement effectively ensures that bait material enters and exits the intermediate chamber 34.
Referring to fig. 3 to 5, in particular, the inner wall of the upper side chamber 33 is provided with a drainage hole 331, and the drainage hole 331 is always located above the upper piston 31.
When the upper chamber 33 is changed between expansion and contraction, the upper piston 31 sucks or discharges seawater into or out of the upper chamber 33 through the discharge hole 331, which facilitates the up-and-down movement of the upper piston 31.
Preferably, the drainage hole 331 opens toward the aquaculture net 1.
When the upper piston 31 sucks the seawater into or out of the upper chamber 33 through the discharge hole 331, the resulting water flow change washes the netting, reducing the attachments on the netting.
Referring to fig. 1, specifically, a spherical cover 5 with a spherical shape is fixedly arranged on the bait collecting plate 4, and the spherical cover 5 protrudes upwards; a bait entrance gap 51 is formed between the edge of the ball mask 5 and the side wall of the bait collecting plate 4.
The ball mask 5 helps to concentrate the bait back into the bait collecting plate 4. In addition, bait passes through the bait entrance gap 51 and enters between the spherical cover 5 and the bait collecting plate 4, and the structure is helpful for the bait to be sucked into the middle cavity 34 by the bait suction pipe 36, so that the working efficiency of the bait suction pipe 36 is improved.
Referring to fig. 1 and 3 to 5, in particular, the transmission mechanism comprises an upper rack 312 and a lower rack 321 with opposite tooth surfaces, and the upper rack 312 and the lower rack 321 are symmetrically arranged with respect to the axis of the bait recycling bin 3; the upper end of the upper rack 312 is fixedly arranged on the upper piston 31, and the lower end is suspended; the lower end of the lower rack 321 is fixedly arranged on the lower piston 32, and the upper end is suspended; a transmission gear 37 is engaged and connected between the upper rack 312 and the lower rack 321, a transmission gear shaft 371 is coaxially and fixedly arranged on the transmission gear 37, and two ends of the transmission gear shaft 371 are respectively rotatably arranged on the inner wall of the middle cavity 34.
When the upper piston 31 slides up and down, the upper piston 31 drives the upper rack 312 to move up and down. Meanwhile, the upper rack 312 synchronously drives the lower rack 321 to move reversely through the transmission gear 37. The upper piston 31 and the lower piston 32 synchronously and reversely slide through the transmission mechanism, so that automatic bait recycling and reusing and automatic oxygen supply are realized, and the transmission mechanism is simple in structure and low in cost.
Referring to fig. 1 and 3 to 5, further, a spring 39 is sleeved on the bait suction pipe 36 between the lower piston 32 and the bottom of the bait recycling cylinder 3; one end of the spring 39 is pressed against the lower piston 32, and the other end is pressed against the bottom of the bait recycling cylinder 3.
As the lower piston 32 slides up and down, the spring 39 changes between restoring and compressing. The spring force generated by the compression of the spring helps balance the force applied to the lower piston 32, thereby improving the stability of the lower piston 32 during sliding.
Referring to fig. 1 and 3 to 5, specifically, a crushing gear 38 is arranged between the transmission gear 37 and the lower piston 32, and the crushing gear 38 is in meshing connection with the transmission gear 37; a pulverizing gear shaft 381 is coaxially and fixedly arranged on the pulverizing gear 38, and two ends of the pulverizing gear shaft 381 are respectively and rotatably arranged on the inner wall of the middle cavity 34.
The possibility of the bait being consumed is reduced by the fact that the bait becomes so agglomerated that it is too bulky or so dense that it is difficult for the fish to digest it after consumption.
The crushing gear 38 is driven by the transmission gear 37 to rotate, and the crushing gear 38 and the transmission gear 37 rotate simultaneously, so that the bait in the middle cavity 34 is crushed and thinned, the fish can effectively eat the bait, and the utilization rate of the bait is further improved.
Preferably, the pulverizing gear 38 is located right above the upper end of the fifth suction pipe 365.
After the bait is sucked into the intermediate chamber 34 by the bait suction pipe 36, the bait is sprayed between the crushing gear 38 and the transmission gear 37 through the fifth suction pipe 365, thereby improving the working efficiency of crushing the bait.
Example two:
