Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a fry water circulation breeding equipment. Background Art

[0002] After 20 to 25 days of feeding, the fry can generally grow to about 3cm, and their weight has increased by dozens or even more than a hundred times, so they need a larger range of activities. At this time, the feeding habits of various fish have begun to differentiate. As the fish grow, the original density is too large, and the water quality and nutritional conditions of the fish pond can no longer meet the requirements of fish growth, so they must be sparsely raised in separate ponds. More importantly, as a fry breeding unit, it is impossible to use all the fry it has cultivated for its own breeding of adult fish, so a considerable number of fry have to be transported to other units or even long-distance transportation. However, the fry are very tender and weak, especially in a captive environment, the fry have poor adaptability to adverse environments such as hypoxia. In order to enhance the physique of the fry and also to adapt them to long-distance transportation, it is usually necessary to carry out 2-3 net-pulling exercises before the fry are separated from the pond.

[0003] Traditional net-pulling training is to use fishing nets to gather the fry manually, thereby improving the fry's ability to adapt to intensive stimulation.

[0004] CN210538196U A kind of automatic net pulling device for fish species in summer flowering stage for aquaculture, including enclosure, rotating wheel, connecting rod, breeding box and motor, the inner upper surface of the enclosure is fixed with a fixed frame, the surface of the block is fixed with a spring, and the surface of the block is installed with a first rotating shaft, the surface of the first rotating shaft is installed with a connecting rod, and the end of the connecting rod is provided with a second rotating shaft, the upper surface of the second rotating shaft is provided with a breeding box, the upper surface of the enclosure is fixed with a support seat, and the surface of the support seat is fixed with a motor, the output end of the motor is fixed with a rotating rod, and the surface of the rotating rod is fixed with a rotating wheel. The automatic net pulling device for fish species in summer flowering stage for aquaculture, the motor lifts the breeding box to concentrate the fry, so that the fish can be exercised by pulling the net in the summer flowering stage. Obviously, the above-mentioned automatic net pulling device still uses the fishing net to concentrate the fry, but it replaces the manual net pulling by the motor driving method, and replaces the fishing net by the breeding box. Although the device can quickly pull the net for exercise, the service life of the mechanical structure will be reduced due to its mechanical structure being immersed in water for a long time.

[0005] Based on this, the technical problem solved in this case is: how to further optimize the automatic net-pulling device to solve the problem of long time and high difficulty in net-pulling training. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a fry water circulation breeding equipment. The equipment can simply achieve the effect of pulling the net to exercise the fry without additional power, and can recycle the water in the breeding pond through the water circulation system to prevent sludge from accumulating at the bottom of the breeding pond and improve the survival rate of the fry.

[0007] The technical solution of the utility model is:

[0008] A fry water circulation breeding equipment comprises a breeding pond and a water circulation system, wherein the water circulation system is used to recycle the water in the breeding pond, and a partition assembly is provided in the breeding pond; the partition assembly comprises a support frame slidably connected in the breeding pond, and a partition net arranged on the support frame and capable of blocking the passage of fry; a weight block which is always in contact with the bottom of the breeding pond is provided at the bottom of the partition net.

[0009] One of the above technical solutions of the utility model has at least one of the following advantages or beneficial effects:

[0010] The utility model reduces the activity range of the fry by means of a partition component arranged in the breeding pond, thereby increasing the density of the fry and achieving the same effect of exercising the fry by pulling a net, such as increasing the amount of exercise and improving the ability to endure hypoxia; at the same time, the water circulation system can adjust the water level in the breeding pond, which can further increase the density of the fry on the one hand, and circulate the water in the breeding pond on the other hand to avoid the large amount of mucus and feces produced by the fry from polluting the water quality, thereby facilitating improving the survival rate of the fry during transportation.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

[0017] See also Figures 1 to 4 A fry water circulation breeding equipment comprises a breeding pond 1 and a water circulation system. The water circulation system is used to recycle the water in the breeding pond 1. A partition assembly 10 is provided in the breeding pond 1; the partition assembly 10 comprises a support frame 101 slidably connected to the breeding pond 1, and a partition net 102 arranged on the support frame 101 and capable of blocking the passage of fry; a weight block 103 is provided at the bottom of the partition net 102 and is always in contact with the bottom of the breeding pond 1.

[0018] In this embodiment, the partition assembly 10 is arranged in the culture pond 1 to reduce the activity range of the fry, thereby increasing their density and achieving the same effect of exercising the fry by pulling the net, such as increasing the amount of exercise and improving the ability to tolerate hypoxia; at the same time, the water circulation system can adjust the water level in the culture pond 1, which can further increase the density of the fry on the one hand, and circulate the water in the culture pond 1 on the other hand to avoid the large amount of mucus and feces produced by the fry from polluting the water quality, thereby helping to improve the survival rate of the fry during transportation.

[0019] In this embodiment, specifically, symmetrical grooves are provided on the left and right sides of the culture pond 1; the support frame 101 is slidably connected in the culture pond 1 through the symmetrical grooves on both sides.

[0020] It should be noted that this embodiment only provides a relatively low-cost sliding connection method. In this field, technicians can achieve sliding connection through other methods, such as screw sliding mechanism, which should also be within the protection scope of this embodiment.

[0021] As a preference in this embodiment, the length of the trough is half the length of the breeding pond 1.

[0022] Obviously, the length of the groove is related to the size of the culture pond 1 and the culture density. In practical application, the length of the groove should be determined according to the different fry species. In this embodiment, the length of the groove is half the length of the culture pond 1, which can meet the density requirements of most fish species. In practical application, the staff should determine the position of the partition net 102 when training the fry according to the density.

[0023] In this embodiment, specifically, the support frame 101 includes two sliders 111 respectively slidably connected to the grooves on both sides, and an installation frame 121 detachably arranged on the sliders 111; a plurality of hooks 122 are arranged on the installation frame 121; and the partition net 102 is arranged on the installation frame 121 through a plurality of hooks 122.

[0024] More specifically, a roller is provided on the slider 111 so that the staff can more easily adjust the position of the support frame 101 . A recess is also provided on the slider 111 , and the recess is used to fix the installation frame 121 .

[0025] Under the above-mentioned preferred embodiment, the partition net 102 can be set on the installation frame 121 through multiple hooks 122, and the weight block 103 is used so that the bottom of the partition net 102 is always in contact with the bottom of the culture pond 1 to prevent the fry from passing through the partition net 102. In actual use, the staff only puts the installation frame 121 into the culture pond 1 when it is necessary to train the fry. On the one hand, it is convenient for the staff to hang the partition net 102, and on the other hand, it can avoid the problems of dirt accumulation and reduced life of the partition net 102 caused by long-term immersion.

[0026] As a preference of this embodiment, the bottom of the culture pond 1 is inclined to the horizontal plane, and gradually inclines from the front side of the culture pond 1 to the back side of the culture pond 1 .

[0027] Under the above-mentioned preferred conditions, the water in the culture pond 1 can flow from high to low, simulating the natural water flow trend, and increasing the activity time of the fry during the cultivation process. It should be noted that in this embodiment, in order to ensure that the partition net 102 can always keep in contact with the bottom of the culture pond 1, the partition net 102 should be reserved for a certain length.

[0028] In this embodiment, the breeding pond 1 is provided with a water inlet 12 arranged on the front side of the breeding pond 1 and a water outlet 21 arranged on the rear side of the breeding pond 1; a leak plate 14 is also provided at the bottom of the breeding pond 1; the water outlet 21 is arranged below the leak plate 14; the height of the water inlet 12 from the ground is greater than the height of the water outlet 21 from the ground.

[0029] In this embodiment, specifically, the water circulation system includes a sedimentation tank 2, a flocculation tank 3, and a water storage tank 4 which are connected in sequence; the sedimentation tank 2 and the water outlet 21 are connected via a water outlet pipe 201; the flocculation tank 3 and the sedimentation tank 2 are connected via a siphon 301; the water storage tank 4 and the flocculation tank 3 are connected via a connecting pipe 501; the water storage tank 4 and the water inlet 12 are connected via a water inlet pipe 401; and a water pump is provided on the water inlet pipe 401.

[0030] More specifically, the short arm of the siphon 301 is inserted into the sedimentation tank 2, and the long arm of the siphon 301 is inserted into the flocculation tank 3, so that the water in the upper part of the sedimentation tank 2 is introduced into the flocculation tank 3, and the unsettled floating objects can be concentratedly extracted by adding flocculants in the flocculation tank 3. Of course, it is also possible to adjust the water ecology by connecting to other biological pools. This embodiment does not provide such a device due to cost and short fry culture cycle considerations.

[0031] In order to control the water level of the culture pond 1 and replace the water, a water supply pipe 402 is provided on the water reservoir 4.

[0032] As a preference of this embodiment, the culture pond 1 is further provided with a fish discharge port 15 arranged on the bottom end of the rear side of the culture pond 1 .

[0033] Under the above-mentioned optimization, this embodiment can easily obtain fry without manual fishing, saving time and labor and improving efficiency.

[0034] As a preference of this embodiment, an oxygenation system 5 is further included; the oxygenation system 5 includes an aerator 51 arranged outside the culture pond 1 and an aeration pipe 52 connected to the bottom of the culture pond 1 .

[0035] Under the above-mentioned preferred embodiment, the aeration pipe 52 at the bottom can increase the oxygen content of the water in the culture pond 1 on the one hand, and on the other hand, the aeration pipe 52 can lift the sludge at the bottom of the culture pond 1 to further prevent sludge accumulation and maintain the water quality in the culture pond 1.
