Description

Technical Field

[0001] The invention relates to the technical field of fish fry breeding cages, and in particular to a disease-proof fish fry breeding cage device. Background Art

[0002] Compared with traditional fish farming models, cage farming of fry has lower costs in terms of feeding, management and fishing. This is because cage farming does not require a large amount of land development, water source management and complex farming equipment, and its output is also higher in actual fry cultivation and farming. Traditional cages are mainly composed of frames and fish nets. The fry are placed in the fish nets and fed regularly. The current fry farming cage devices need to replace large-aperture fish nets as the fry grow. The fry usually need to be salvaged to change ponds, which is not convenient for quickly changing the aperture of the fish net. The fry are also easily damaged when changing ponds. At the same time, the site area requirements are high. At the same time, when disease prevention agents are placed in traditional cages, the agents are easy to spread, which is not convenient for quickly closing the cages for water change, which has a greater impact on water quality. It is also not convenient to know the weight changes of fry growth. The traditional unified salvage and load-bearing method has a high mortality rate due to lack of oxygen. Summary of the invention

At this time, medicine can be put into the waterproof cloth 401 to treat fish diseases. After the medicine is put, the breeding water containing medicine in the waterproof cloth 401 can be directly extracted and discharged independently from the fish pond. The waste water bucket can be prepared for recycling and treatment, and clean water is gradually added to the waterproof cloth 401 for dilution. ;

It can be more suitable for fry management. The structure is simple to operate and avoids the problem of inaccurate manual observation of the size of the fry. The structure can quickly scoop up the fry, weigh them and then put them into the water to avoid death losses caused by long-term dehydration. The separation outer edge 703 can be adjusted according to the amount of breeding. The more fry there are, the higher the separation outer edge 703 should be to prevent overturning.

[0041] Embodiment 2, on the basis of embodiment 1, the separation water replenishment member 8 comprises: a water spray cleaning circle 801 and a humidifying strip 802, the water spray cleaning circle 801 is fixedly mounted on the bottom of the sliding cover plate 104; a circle of nozzles is tiltedly arranged at the bottom of the water spray cleaning circle 801, and the nozzles at the bottom of the water spray cleaning circle 801 are used to wash the inside of the cylindrical fish net 302; a humidifying strip 802 is fixedly mounted on the water spray cleaning circle 801, the humidifying strip 802 is connected to the water spray cleaning circle 801, and a row of nozzles is arranged at the bottom of the humidifying strip 802; the humidifying strip 80 The nozzle at the bottom is used for spraying the fry; the separation water supply component 8 also includes: a water receiving pipe 803, which is fixedly installed on the humidification strip 802; the water receiving pipe 803 is externally connected to a water pump, and the separation water supply component 8 can be used to spray water to clean the cylindrical fish net 302, improve the cleanliness of the cylindrical fish net 302, and improve the water flow rate. Through the humidification strip 802, water can be sprayed on the fry when weighing the fry, so as to prevent the fry from being damaged by hypoxia caused by dehydration, and further prevent the damage of the fry from weighing, thereby ensuring the rationality of the structure.

[0042] The working principle of this embodiment is as follows: first, the fry can be poured into the structure through the four slots provided on the sliding cover plate 104 for feeding. As the fry grows and the cylindrical fish net 302 is used for a long time and adheres to certain impurities, when it needs to be replaced, the valve on the hose of the air guide bag 203 is opened, and the pressure of the positioning air bag 201 is reduced. At this time, the positioning air bag 201 limits the positioning iron ring 301 elastically, and the positioning iron ring 301 below can be directly extracted from the outside of the positioning air bag 201. At this time, the positioning air bag 201 is elastic and can fit the cylindrical fish net 302 below to prevent the fry from escaping. The third positioning iron ring 301 from top to bottom is lifted up and snapped into the positioning air bag 2 below. 01, at this time, the second positioning iron ring 301 can be inserted into the positioning airbag 201 above to realize the replacement of the cylindrical fish net 302. After the staff quickly presses the air guide bag 203, the positioning airbag 201 is controlled to expand and fix it in place, and the valve on the hose on the positioning airbag 201 is rotated. The operation is simple, and the replaced cylindrical fish net 302 at the top can be simply folded and folded. Holding the handle 303, the top positioning iron ring 301 is magnetically attached to the anti-drop magnet 106 for positioning. In this way, the three cylindrical fish nets 302 can be replaced. This structure can be easily folded and recycled. The two positioning bolts 105 can be removed by rotation. At this time, the sliding cover plate 104 can be The support column 103 slides up and down, close to the support base 101, reducing space occupation. In normal breeding work, the waterproof cloth 401 is in a lowered state, and the magnetic ring 402 is normally placed underwater to prevent the waterproof cloth 401 from blocking the cylindrical fish net 302. When it is necessary to put medicine on the fry, the magnetic ring 402 is lifted and magnetically attracted to the positioning iron ring 301 located on the outside of the sliding cover plate 104 for positioning. At this time, the waterproof cloth 401 will surround the outside of the cylindrical fish net 302, which can play an isolation role. Then, the receiving drive screw rod 501 is rotated to drive the receiving plate 502 to move up and stick to the bottom of the support base 101, closing the bottom of the support base 101 to prevent leakage of medicine. At this time, the waterproof cloth 401 can be placed on the bottom of the support base 101. The medicine is put into the pond to cure fish diseases. After the medicine is put into the pond, as the drug treatment is completed, the breeding water containing the medicine in the waterproof cloth 401 can be directly extracted and discharged independently from the fish pond. A waste water bucket can be prepared for recycling and treatment. After gradually adding clean water to the waterproof cloth 401 for dilution, the magnet ring 402 can be removed to prevent the waterproof cloth 401 from blocking the flow of the cylindrical fish net 302. At the same time, the receiving drive screw rod 501 is rotated to drive the receiving plate 502 to move downward. After the receiving plate 502 moves downward, it does not block the water flow through the mesh of the support base 101. At the same time, the mesh of the support base 101 can leak feces to the receiving plate 502 for collection. Later, only the receiving plate 502 needs to be cleaned to reduce the pollution to the bottom of the pond.

[0043] The manual handheld weighing scale is hung on the pulling wire rope 701, and the weighing scale can be lifted by multiple people, which drives the separation plate 702 to be lifted. At this time, the mesh holes on the separation plate 702 will drain water. When the bottom of the separation plate 702 is out of the water surface, the fry on the separation plate 702 can be weighed, and the separation plate 702 can be immediately lowered into the water after reading the weight; when replacing the cylindrical fish net 302, the water pump connected to the water receiving pipe 803 can be turned on, and the cylindrical fish net 302 can be sprayed with water through the water spray cleaning circle 801 to clean it. At the same time, when lifting the separation plate 702, the water pump connected to the water receiving pipe 803 can be turned on, and the humidification strip 802 can also spray water to the fry to moisturize and oxygenate the fry to prevent the fry from lack of oxygen.
