Description

Technical Field

[0001] The utility model relates to the technical field of fish tanks, in particular to a circulating fish tank for breeding. Background Art

[0002] In the process of fish farming, since temperature has an important impact on the survival of fish, and different types of fish have different requirements for water temperature, one or more thermometers are usually installed inside the fish tank to monitor the water temperature in the fish tank in real time.

[0003] Patent CN202396308U discloses a fish tank. By setting a thermometer on the fish tank, the water temperature in the fish tank can be accurately understood, so that the water temperature can be adjusted to a suitable temperature in time to improve the survival rate of the fish. The water flow in the above-mentioned fish tank is relatively static, so it is suitable for breeding some ornamental fish. However, when it is necessary to breed fish with high mobility such as long-snouted catfish, the above-mentioned fish tank cannot be applied. Even if the volume of the fish tank is expanded, the habit of long-snouted catfish to swim against the current cannot be satisfied because the water flow in the fish tank is relatively static, which is not conducive to the breeding of long-snouted catfish. It can be seen that in order to breed fish with high mobility such as long-snouted catfish, a fish tank that can change the water flow rate in the cylinder is needed. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a circulating fish tank, which can change the speed of water flow in the tank to adapt to the habit of fish swimming against the current.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] As a further solution of the utility model: the cylinder body is barrel-shaped, the axial direction of the guide pipe is parallel to the axial direction of the cylinder body, and the guide pipe is arranged at the eccentric position of the cylinder body; the spray direction of the water spray hole is arranged along the circumferential direction of the cylinder body.

[0008] As a further solution of the utility model: the water spray holes are evenly arranged in sequence along the axial direction of the guide pipe.

[0009] As a further solution of the utility model: the water pump is a submersible pump, and the submersible pump is installed at the bottom of the inner side of the cylinder body.

[0013] As a further solution of the utility model: the spoiler columns arranged in sequence and at equal distances along the same straight line constitute a spoiler group, and multiple spoiler groups are arranged in sequence along the swimming direction of the fish.

[0014] As a further solution of the utility model: the spoiler column is bonded to the inner bottom surface of the cylinder body by gluing.

[0026] 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.

[0027] See also Figure 1 to Figure 5 In the embodiment of the utility model, a circulating fish tank comprises a cylindrical cylinder body 1, which is made of transparent glass. A submersible pump as a water pump 2 is fixedly installed on the inner bottom surface of the cylinder body 1, and the initial port of the submersible pump is connected to a guide pipe 21 located below the water surface of the cylinder body 1. The guide pipe 21 is provided with water spray holes 212 for water spraying, and each water spray hole 212 is uniformly arranged in sequence along the axial direction of the guide pipe 21. The axial direction of the guide pipe 21 is parallel to the axial direction of the cylinder body 1, and the guide pipe 21 is arranged at the eccentric position of the cylinder body 1. By changing the water pumping power of the submersible pump, the water output of the submersible pump is changed, and in addition, the speed of the water flow in the cylinder body 1 can be changed by cooperating with the guide pipe 21 and the water spray hole 212, so that a circulation is formed inside the cylinder body 1. At this time, in order to maintain stability, the fish will swim against the current, and will not be carried away by the water flow, thereby improving the activity of the fish and facilitating the growth of the fish.

[0028] At the same time, in order to observe the temperature of the water flow inside the cylinder 1, a plurality of thermometers for detecting the water temperature are installed in the cylinder 1, so as to adjust the water temperature in real time according to the thermometer readings to adjust the water temperature to a temperature suitable for fish growth.

[0029] like Figure 3 As shown, a spoiler column 3 is fixedly installed in the cylinder body 1, and the spoiler column 3 is fixedly connected to the inner bottom surface of the cylinder body 1 by gluing, and the spoiler column 3 is arranged on the swimming path of the fish, and a channel for the fish to pass through is formed between adjacent spoiler columns 3. The length direction of each spoiler column 3 is parallel to the axial direction of the cylinder body 1. Of course, the length direction of each spoiler column 3 can also be arranged at will, but in order to improve the convenience of installation, it is preferred to be parallel to the axial direction of the cylinder body 1.

[0030] like Figure 4As shown, each spoiler column 3 is equidistantly arranged in sequence along a straight line perpendicular to the fish swimming path, that is, each spoiler column 3 is equidistantly arranged in sequence along the radial direction of the cylinder body 1. Multiple spoiler columns 3 can change the flow state of the fluid near the spoiler columns 3 while providing obstacles for the flow of the fish, so that when the fish swims against the current, it needs to avoid the spoiler columns 3 in time, thereby improving the coordination of the fish muscles and facilitating the growth of the fish meat quality.

[0031] like Figure 5 As shown, each spoiler column 3 arranged equidistantly along the same straight line constitutes a spoiler group, and multiple spoiler groups are arranged in sequence along the swimming direction of the fish. That is, each spoiler group is evenly arranged in sequence along the circumference of the cylinder body 1 to form a firework-like structure. The arrangement of multiple spoiler groups can increase the number of obstacles, thereby gradually improving the flexibility of the fish in the process of swimming between multiple obstacles.

[0032] A certain number of long-snout catfish are cultured in a cylinder 1 with an inner diameter of 50 cm and a water depth of 70 cm. The speed of the water flow is changed by changing the power of the submersible pump. The speed of the water flow is detected by a tachometer, such as setting the water flow speed to 30 cm / s, 20 cm / s or 10 cm / s. The long-snout catfish are grown at the corresponding flow rate. After a certain period of growth, biological sampling is performed on the long-snout catfish to study the growth performance and body indicators of the long-snout catfish, such as the nutritional components, texture characteristics, muscle tissue, etc. of the fish meat, so as to study the influence of the water flow speed on the growth state of the long-snout catfish.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
