Description

Technical Field

[0001] This invention relates to the field of fish farming technology, and in particular to a fish nest for collecting the spawning eggs of Pengze crucian carp. Background Technology

[0002] Crucian carp are warm-water fish that prefer to live at the bottom of the water. They are highly adaptable to low oxygen levels and are omnivorous. There are many varieties of crucian carp that are artificially raised. In southern my country, the climate is suitable for crucian carp to live and reproduce, resulting in a large number of regionally distinctive crucian carp species. Pengze crucian carp is a unique crucian carp species native to Pengze. In the process of raising them, fish nests are laid to assist the Pengze crucian carp in their reproduction. Afterwards, the aquatic plants in the fish nests are collected by the farmers to collect and cultivate the fish eggs. However, the existing equipment is inconvenient for collecting the aquatic plants in the fish nests. It is necessary to constantly remove and put back the aquatic plants and then collect the fish eggs from the aquatic plants, which greatly affects the collection efficiency.

[0003] Therefore, in order to address the above problems, a fish nest for collecting the eggs of Pengze crucian carp is being developed, which can centrally suspend aquatic plants, making it easier to remove the aquatic plants and thus easier to collect the fish eggs. Summary of the Invention

[0004] To overcome the shortcomings of existing devices that are inconvenient to collect aquatic plants in fish nests, requiring constant removal and replacement of the plants, which greatly affects collection efficiency, this invention provides a fish nest for collecting the eggs of Pengze crucian carp, which can centrally suspend the aquatic plants, making it easier to retrieve them and thus easier to collect the fish eggs.

[0005] The technical implementation of the present invention is as follows: a fish nest for collecting the eggs of crucian carp spawning in Pengze, comprising a floating frame, fixing blocks, air bladders, a collection mechanism and a lifting mechanism. Multiple fixing blocks are connected to the top of the floating frame, and air bladders are connected between the fixing blocks. The air bladders can assist the floating frame in floating.

The bottom of the first pull rod is connected to the fixed frame.

[0008] Optionally, it also includes a protective mechanism, which includes a protective shell, a connecting frame, a first torsion spring, a guide frame, a limiting block, and a spring. Four connecting frames are connected to the fixed frame, and two protective shells are rotatably connected to each connecting frame. Each protective shell can protect the aquatic plants. A first torsion spring is connected between each protective shell and the connecting frame. The first torsion spring is wound around the adjacent connecting frame. A guide frame is connected to each connecting frame, and two limiting blocks are slidably connected to each guide frame. Each limiting block can push the adjacent protective shell. A spring is connected between the adjacent limiting blocks.

[0009] Optionally, it also includes a closing mechanism, which includes a connector, a pull rope, a guide wheel, and a second pull rod. The adjacent limit blocks are connected by connectors, and each connector is connected to a pull rope at its top. Each first pull rod is rotatably connected to multiple guide wheels at its top. Each pull rope is in contact with an adjacent guide wheel, and each guide wheel can guide the movement of the pull rope. Each first pull rod is connected to a second pull rod, and each pull rope is connected to the second pull rod.

[0010] Optionally, it also includes a bottom support mechanism, which includes a support plate, connecting rods and a limiting frame. A limiting frame is placed between the first connecting rods, and multiple connecting rods are connected to the limiting frame. A support plate is connected between two adjacent connecting rods, and the support plate is used to support the aquatic plants.

[0011] Optionally, it also includes a limiting mechanism, which includes a second fixed seat, a limiting frame, and a second torsion spring. Multiple second fixed seats are connected to the floating frame, and each second fixed seat is rotatably connected to a limiting frame.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] A fish nest for collecting the eggs of the Pengze crucian carp, such as Figure 1 and Figure 2 As shown, it includes a floating frame 1, fixing blocks 2, airbags 3, a collection mechanism 4 and a lifting mechanism 5. The top of the floating frame 1 is connected to four fixing blocks 2, and airbags 3 are connected between the fixing blocks 2. The floating frame 1 is equipped with a collection mechanism 4 and a lifting mechanism 5.

[0035] In the breeding of Pengze crucian carp, this device can be used to collect the fish eggs produced by the Pengze crucian carp in order to assist in the reproduction of Pengze crucian carp. First, through the cooperation between the air bag 3 and the floating frame 1, the floating frame 1 can float on the surface of the fish pond. Then, aquatic plants are hung on the collection mechanism 4 for camouflage. After that, the device is placed in the fish pond. When Pengze crucian carp are spawning, they will look for places with abundant aquatic plants to spawn, thus leaving the fish eggs in the aquatic plants. After that, the breeder only needs to lift the collection mechanism 4 upwards through the lifting mechanism 5 and collect the fish eggs.

[0036] like Figure 1 , Figure 3 and Figure 4 As shown, the collection mechanism 4 includes a fixed frame 41, a fixed bracket 42, a pin 43, a collection net 44, and ropes 45. The bottom of the floating frame 1 is connected to the fixed frame 41 by four ropes 45. Four fixed brackets 42 are snapped onto the fixed frame 41. Each fixed bracket 42 is threadedly connected to a pin 43, and each fixed bracket 42 is connected to a collection net 44.

[0037] When it is necessary to collect the eggs of Pengze crucian carp, aquatic plants can be hung on the collection net 44 for camouflage. When the Pengze crucian carp reach their spawning time, they will seek out the aquatic plants to lay their eggs. Then, by lifting the fixing frame 41 upwards and rotating the pin 43, the fixing bracket 42 is no longer fixed to the fixing frame 41. Finally, the fixing frame 41 can be removed, and the aquatic plants on the collection net 44 can be collected. In summary, by suspending aquatic plants on the collection net 44, a suitable spawning environment for Pengze crucian carp can be simulated and camouflaged, which also makes it easier for aquaculture personnel to quickly collect the fish eggs.

[0038] like Figure 1 , Figure 5 and Figure 6 As shown, the lifting mechanism 5 includes a first fixed seat 51, a first connecting rod 52, a second connecting rod 53, and a first pull rod 54. The four first fixed seats 51 are connected to the floating frame 1 by bolts. The first connecting rod 52 is rotatably connected to each of the first fixed seats 51. The second connecting rods 53 are rotatably connected to the first connecting rods 52. The first pull rod 54 is rotatably connected between the second connecting rods 53. The top of the first pull rod 54 has a gripping groove for easy gripping. The bottom of the first pull rod 54 is connected to the fixed frame 41.

[0039] When it is necessary to collect the aquatic plants on the collection net 44, the first lever 54 can be pulled directly through the grip groove, which will cause the second connecting rod 53 to rotate, and then the first connecting rod 52 to rotate. At this time, the first connecting rod 52 will form a straight line with the adjacent second connecting rod 53, and at the same time form an angle with the floating frame 1, making it easy for the aquaculture personnel to hold. In summary, by pulling the first lever 54, the first connecting rod 52 and the second connecting rod 53 will rotate, which makes it easy for the aquaculture personnel to collect and take the aquatic plants on the collection net 44.

[0040] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a protective mechanism 6, which includes a protective shell 61, a connecting frame 62, a first torsion spring 63, a guide frame 64, a limiting block 65, and a spring 66. Four connecting frames 62 are connected to the fixed frame 41. Two protective shells 61 are rotatably connected to each connecting frame 62. A first torsion spring 63 is connected between each protective shell 61 and the connecting frame 62. The guide frames 64 are all connected to the connecting frames 62. Two limiting blocks 65 are slidably connected to each guide frame 64. A spring 66 is connected between adjacent limiting blocks 65.

[0041] When aquatic plants need protection, to prevent them from encountering obstacles during their upward movement and thus being affected, the limiting blocks 65 can be pushed upwards, causing the springs 66 to be stretched. As the limiting blocks 65 continue to slide upwards, the protective shells 61 are no longer limited. Initially, the first torsion spring 63 is in a state of deformation. Under the action of the first torsion spring 63, the protective shells 61 will rotate and close, protecting the aquatic plants. In summary, the protective shells 61 protect the aquatic plants, preventing them from being pulled or obstructed during movement and affecting the normal collection of fish eggs.

[0042] like Figure 1 , Figure 9 and Figure 10 As shown, it also includes a closing mechanism 7, which includes a connector 71, a pull rope 72, a guide wheel 73, and a second pull rod 74. The connector 71 is connected between adjacent limit blocks 65. The top of each connector 71 is connected to a pull rope 72. The top of each first pull rod 54 is rotatably connected to four guide wheels 73. The top of the first pull rod 54 is connected to the second pull rod 74. The pull ropes 72 are all connected to the second pull rod 74. The top of the second pull rod 74 has a pull ring, which makes it easy for the breeder to pull the second pull rod 74.

[0043] To facilitate the closure of the protective shell 61, when it is necessary to collect fish eggs inside the aquatic plants, the second lever 74 is pulled upwards, causing the first lever 54 to move upwards. Simultaneously, the second lever 74 drives the pull rope 72 to move, causing the connector 71 to slide upwards along with the limiting block 65, thus achieving the effect of quickly closing the protective shell 61. In summary, by pulling the second lever 74, the pull rope 72 is pulled, causing the connector 71 to move along with the limiting block 65, achieving the effect of quickly closing the protective shell 61 and protecting the aquatic plants and fish eggs.

[0044] like Figure 1 and Figure 11 As shown, it also includes a bottom support mechanism 8, which includes a support plate 81, connecting rods 82 and a limiting frame 83. The limiting frame 83 is placed between the first connecting rods 52, and eight connecting rods 82 are connected to the limiting frame 83. The support plate 81 is connected between two adjacent connecting rods 82.

[0045] When collecting fish eggs from the aquatic plants, as the aquatic plants are pulled upwards, the support plate 81 continuously supports the bottom of the aquatic plants, improving their stability. At the same time, as the first connecting rod 52 rotates, it pushes the limiting frame 83 upwards, which in turn causes the connecting rod 82 to drive the support plate 81 upwards. In summary, by supporting the aquatic plants with the support plate 81, the stability of the aquatic plants is improved, and the accidental detachment of the aquatic plants is prevented.

[0046] like Figure 1 , Figure 12 and Figure 13 As shown, it also includes a limiting mechanism 9, which includes a second fixed seat 91, a limiting frame 92, and a second torsion spring 93. Four second fixed seats 91 are connected to the floating frame 1. Each second fixed seat 91 is rotatably connected to a limiting frame 92. The limiting frames 92 are all L-shaped structures with a sloping bottom, which can limit and support the fixed frame 41 and facilitate the fixed frame 41 to push the limiting frame 92. A second torsion spring 93 is connected between the limiting frame 92 and the adjacent second fixed seat 91.

[0047] To improve the convenience of fish egg collection, when the fixed frame 41 moves upward, it comes into contact with the limiting frame 92, which pushes the limiting frame 92. The second torsion spring 93 is deformed under force. Then, as the fixed frame 41 continues to move, the limiting frame 92 supports the fixed frame 41. The aquaculture personnel no longer need to hold the fixed frame 41 in place, which improves the ease of use.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
