Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a circular track water tank structure. Background Technology

[0002] The golden apple snail (Pomacea canaliculata) is a large snail native to the Amazon River basin in South America. It was introduced to my country in 1981 as a special aquatic economic animal for farming and promotion, but was later abandoned due to its unpleasant taste. In 2000, the golden apple snail was listed by the International Union for Conservation of Nature (IUCN) as one of the world's 100 most dangerous invasive alien species, and in 2003, it was included in the first batch of invasive alien species lists for China. Currently, the invasion situation of the golden apple snail in my country is very serious. It is widely distributed in most areas south of the Yangtze River and shows a trend of gradually spreading from south to north.

[0003] Control techniques for golden apple snails mainly include physical, chemical, and biological control. Physical control primarily involves manual snail and egg removal, high-pressure water jet spraying, and setting up interception nets at irrigation water inlets and outlets. This method is simple to operate, easy to manage, and widely implemented, but it also has significant drawbacks, such as requiring substantial manpower, material resources, and financial investment, and its snail-killing effect is not ideal. Chemical control is mainly suitable for emergency eradication in farmland, using agents such as methomyl, molluscicides, and ethoxysulfuron-methyl to spray directly into the fields, achieving significant snail-killing effects. However, these agents can pollute the aquatic environment and even kill other aquatic animals such as fish and shrimp, making frequent large-scale use unsuitable. Biological control is currently considered one of the green, environmentally friendly, low-cost, and sustainable methods. It mainly utilizes the natural enemies of golden apple snails, such as mallards, grass carp, and common carp, to prey on and kill them, and has certain value for widespread application. However, biological control also carries certain risks. On the one hand, some natural enemies may not be able to adapt to the local environment, resulting in low survival rates and failing to achieve the desired snail control effect. On the other hand, the introduction of natural enemies may affect the structure of aquatic animal communities and reduce the stability of aquatic ecosystems.

[0004] Studies have shown that flow velocity can significantly affect the growth characteristics of fish. Moderate flow velocity is beneficial for improving specific growth rates in fish, but as the flow velocity continues to increase, the specific growth rate tends to decrease. For example, Liu Mei et al. studied the growth performance of largemouth bass under flow velocities of 0 m / s, 0.2 m / s, 0.4 m / s, and 0.6 m / s, and found that the specific growth rate of largemouth bass in the 0.4 m / s flow velocity group was significantly higher than that of the other three treatment groups. Hu Jia et al. conducted a comparative study on the growth of juvenile sturgeon under different flow velocities, and found that it had the best growth effect at a flow velocity of 3 BL / s, followed by 2 BL / s and 4 BL / s. Wang Jie studied the effect of flow velocity on the growth of juvenile Scorpionfish Xu's and found that when the flow velocity was less than 1.5BL / s, the growth of Scorpionfish Xu's increased with the increase of flow velocity. However, when the flow velocity continued to increase to 2.5BL / s, all growth indicators of juvenile Scorpionfish Xu's decreased compared with the 1.5BL / s flow velocity group.

[0005] Indoor experiments showed that the growth response mechanism of the golden apple snail to flow velocity is similar to that of fish; that is, a suitable flow velocity promotes the growth of the golden apple snail, but when the flow velocity continues to increase, it restricts the growth of the golden apple snail. Therefore, flow velocity may be one of the key factors limiting the growth of the golden apple snail.

[0006] Existing studies typically conduct golden apple snail control experiments using square water tanks or containers under still water conditions. The key to conducting experiments on flow velocity control of golden apple snails is to design a water tank that can meet the requirements of water circulation and maintain a relatively stable flow velocity under flowing conditions.

[0007] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Example 1

[0023] See Figure 1 and Figure 2 The figure shows a ring-shaped running track water trough structure, including a ring-shaped bottom plate 100, an inner ring plate 200, and an outer ring plate 300. In this embodiment, the ring-shaped bottom plate 100 has an elliptical ring structure, and the cross-sections of the inner ring plate 200 and the outer ring plate 300 are elliptical.

[0024] The lower periphery of the inner annular plate 200 is sealed to the inner periphery of the bottom plate 100 of the annular trough. The outer annular plate 300 is located on the outer periphery of the inner annular plate 200, and its lower periphery is sealed to the outer periphery of the bottom plate 100 of the annular trough. This allows the bottom plate 100 of the annular trough, the inner annular plate 200, and the outer annular plate 300 to form an annular water tank track 10 for holding experimental water. This allows the water to circulate within the annular water tank track 10, maintaining a relatively stable water flow velocity to meet the requirements of the golden apple snail control experiment.

[0025] To improve the overall structural stability of the circular track water tank structure, upper and lower reinforcing hoops 310 and 320 are provided at the upper and lower ends of the outer circumferential surface of the outer circular plate 300. Eight external support vertical plates 330 are circumferentially spaced on the outer circumferential surface of the outer circular plate 300. The upper and lower ends of each external support vertical plate 330 are connected to the upper and lower reinforcing hoops 310 and 320, and its inner surface is connected to the outer circumferential surface of the outer circular plate 300. Of course, the number of external support vertical plates 330 is not limited to that in this embodiment and should be designed according to actual needs. In this embodiment, the circular track water tank structure utilizes the upper and lower reinforcing hoops 310 and 320 and several external support vertical plates 330 to reinforce the outer circular plate 300, ensuring the structural stability of the outer circular plate 300 and preventing deformation of the outer circular plate 300 after being filled with water, which would affect the effectiveness of the control experiment. Similarly, upper and lower inner reinforcing hoops 210 and 220 are provided at the upper and lower ends of the inner circumferential surface of the annular inner side plate 200. Eight inner support vertical plates (not shown in the figure) are circumferentially spaced on the inner circumferential surface of the annular inner side plate 200. The upper and lower ends of each inner support vertical plate are connected to the upper and lower inner reinforcing hoops 210 and 220, and its inner surface is connected to the inner circumferential surface of the annular inner side plate 200. Of course, the number of inner support vertical plates is not limited to that in this embodiment and should be designed according to actual needs. In this embodiment, the annular runway water tank structure uses upper and lower inner reinforcing hoops 210 and 220 and several inner support vertical plates to reinforce the annular inner side plate 200, ensuring the structural stability of the annular inner side plate 200 and preventing deformation of the annular inner side plate 200 after being filled with water, which would affect the effectiveness of the control experiment.

[0026] The bottom plate 100 of the annular groove, the inner annular plate 200, the outer annular plate 300, the upper and lower outer reinforcing rings 310 and 320, the several outer support vertical plates 330, the upper and lower inner reinforcing rings 210 and 220 and the several inner support vertical plates are all made of rigid plastic, which reduces the manufacturing cost. The connection between them is made by adhesive to ensure the reliability and sealing of the connection.

[0027] Example 2

[0028] The circular running track water trough structure in this embodiment is largely the same as the circular running track water trough structure in Embodiment 1, the difference being in their reinforcement structures. Specifically, see... Figure 3In this embodiment, the annular racetrack water tank structure has a plurality of first connecting crossbeams 410a circumferentially spaced between the inner annular plate 200a and the outer annular plate 300a. The inner end of each first connecting crossbeam 410a is connected to the outer circumferential surface of the inner annular plate 200a, and its outer end is connected to the inner circumferential surface of the outer annular plate 300a. The lower end face of each first connecting crossbeam 410a is higher than the highest liquid level of the experimental water body in the annular racetrack 10a to avoid affecting the experimental water body. In this embodiment, the annular racetrack water tank structure securely connects the inner annular plate 200a and the outer annular plate 300a through the plurality of first connecting crossbeams 410a, improving the structural stability between the inner annular plate 200a and the outer annular plate 300a and preventing deformation of the inner annular plate 200a and the outer annular plate 300a after being filled with water.

[0029] Several second connecting crossbeams 420a are arranged radially at intervals within the annular inner side plate 200a. The two ends of each second connecting crossbeam 420a are connected to the inner circumferential surface of the annular inner side plate 200a, thereby improving the structural stability of the annular inner side plate 200a.

[0030] The bottom plate 100a of the annular groove, the inner annular plate 200a, the outer annular plate 300a, several first connecting crossbeam plates 410a and second connecting crossbeam plates 420a are all made of rigid plastic, which reduces the manufacturing cost. The connection between them is made by adhesive bonding to ensure the reliability and sealing of the connection.
