Description

TECHNICAL FIELD

[0001] The utility model relates to fish culture technical field, and specifically, relate to a small fish culture device. BACKGROUND

[0002] Small catfish (such as white edge catfish, black tail catfish, cold water catfish) fish is similar to mud eel and loach, usually likes to live in the nest, therefore, small catfish fish usually adopts the tool similar to artificial mud eel nest to provide habitat for fish when breeding, however, the inside of mud eel nest is wrinkle (that is, has certain bending), however, the body of small catfish fish cannot twist like mud eel and loach, so it cannot turn in the mud eel nest, and is easy to be stuck in the nest and lead to death.

[0003] In order to solve the above problems, the applicant's prior Chinese application (application number "2024216173086") provides a small fish culture device, which comprises a supporting piece, a supporting rod and a plurality of nest plates, the plurality of nest plates are sequentially sleeved on the supporting rod, and at least one supporting rod is arranged at each end of the nest plate, the ends of the supporting rod are provided with limiting pieces, the two sides of the thickness direction of the nest plate are both provided with a plurality of straight half grooves, the two half grooves at the corresponding positions of the adjacent sides of the adjacent nest plates form a habitat channel, which avoids being stuck due to the inability of the fish body to twist greatly; meanwhile, a plurality of supporting pieces are arranged on the supporting rod at intervals, each groove plate is supported by the supporting piece, and the distance between the two adjacent supporting pieces is greater than the thickness of the nest plate, so that each nest plate can move a certain distance upward, avoiding the death of some fish with larger body size being stuck in the habitat channel.

[0004] However, in the technical solution of the prior application, the overall height of the culture device is limited by the length of the supporting rod, and the culture device cannot be telescoped as a whole, which is not convenient in the later fishing, cleaning and other processes.

[0021] Reference Figures 1-3 A small fish farming device, comprising a plurality of nest plates and a plurality of connecting columns 2. The two sides of the nest plate in the thickness direction are spaced apart and provided with a plurality of linear half grooves 101 ("linear" means that the length direction of the half groove 101 has no bending, which is a straight line). In actual application, a plurality of groove plates 1 are arranged along the thickness direction of the groove plate 1, and the adjacent groove plates 1 are connected by the connecting column 2. The two half grooves 101 at the corresponding positions of the adjacent sides of the adjacent nest plates enclose the habitat channel.

[0022] The cross section of the half groove 101 perpendicular to the length direction in this embodiment is semicircular, which avoids the edges of the groove bottom, that is, the fish feed falls on the edges when feeding, and the fish cannot eat it, thereby causing the accumulation of fish feed. Of course, in other embodiments, the cross section of the half groove 101 perpendicular to the length direction can also be designed into other shapes.

[0023] The half grooves 101 on both sides of the nest plate are arranged in a staggered manner, so that the thickness of the nest plate can be greatly reduced, and the weight is reduced. In other embodiments, if the weight is not considered, the half grooves 101 on both sides of the nest plate can also be arranged relatively. In actual application, the nest plate is made of plastic or aluminum alloy, which is as light as possible, and the half groove 101 is polished smooth to ensure smooth swimming of the fish.

[0024] Reference Figure 4 One end of the connecting column 2 is provided with an external thread 201, and the other end of the connecting column 2 is provided with a limiting block 202. In actual application, the connecting column 2 can be replaced by a bolt or a screw, and the head of the bolt or the screw serves as the limiting block 202. Among the two adjacent groove plates 1, one groove plate 1 is provided with a threaded hole 103 for connecting with the external thread 201 of the connecting column 2, and the other groove plate 1 is provided with a through hole 104 for the connecting column 2 to pass through. In this way, the two adjacent groove plates 1 can have a space for moving away from or close to each other, thereby enabling the entire farming device to be contracted or stretched (i.e., the whole is shortened or lengthened), which is more convenient to use in the later fishing, cleaning and other processes. In addition, the connecting depth of the external thread 201 of the connecting column 2 and the threaded hole 103 on the groove plate 1 can be adjusted to adjust the moving distance between the adjacent groove plates 1.

[0025] When the connecting column 2 connects two adjacent groove plates 1, the limiting block 202 is used to limit the maximum distance between the two adjacent groove plates 1, that is, when the external thread 201 of the connecting column 2 is connected with the threaded hole 103 of one of the groove plates 1, the adjacent groove plates 1 abut against the limiting block 202, and the distance between the two adjacent groove plates 1 is the maximum. In the embodiment, one end of the through hole 104 is provided with a countersunk head 105 for accommodating the limiting block 202, that is, the limiting block 202 is hidden in the countersunk head 105, which helps to reduce the overall height of the breeding device.

[0026] On the basis, the two ends of the groove plate 1 are connected with at least two connecting columns 2. For the convenience of description, the two ends of the groove plate 1 connected with the connecting columns 2 are defined as left end and right end, for the convenience of understanding, that is, corresponding to the left end and the right end in Figure 1 , one of the two adjacent groove plates 1 is provided with a threaded hole 103 at the left end and a through hole 104 at the right end, and the other groove plate 1 is provided with a through hole 104 at the left end and a threaded hole 103 at the right end, that is, the directions of the connecting columns 2 connected at the two ends of the adjacent groove plates 1 are opposite, on the basis, that is, the limiting block 202 of the left end connecting column 2 faces downward (as shown in Figure 2 ), and the limiting block 202 of the right end connecting column 2 faces upward (as shown in Figure 3 ). It is worth mentioning that the connecting mode of the connecting column 2 arranged in the above manner can make all the groove plates 1 have only one specification, and when used, one of the two adjacent groove plates 1 is flipped by 180° relative to the other groove plate 1.

[0027] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
