Description

Technical Field

[0001] The utility model belongs to the technical field of aquaculture, and in particular relates to a shrimp breeding experimental box in a laboratory environment. Background Art

[0002] Aquaculture is significantly influenced by seasons and the environment. Seedling and breeding are crucial processes in aquaculture research, and they require a long timeframe. Due to seasonal constraints, experimental research on seedling and breeding cannot be conducted in a short period of time. Although dedicated breeding greenhouses have been established at the aquaculture base, they can only adjust the ambient temperature within a narrow range, centered on the outside temperature, and are unable to simulate the aquaculture environment under all-season conditions to meet experimental needs.

[0003] Publication No. CN115500298A describes a "shrimp breeding system" with evenly spaced screens and perforated screens within a culture tank. Circulation pipes are installed on both sides of the tank, located near the bottom. A circulating heating mechanism is installed on one side of the tank. This mechanism includes an insulated housing, with the ends of the circulation pipes connected to vertically arranged heating pipes. Connecting pipes are evenly spaced on the heating pipes, connecting to first diverter pipes, which are evenly spaced horizontally. Second diverter pipes are evenly spaced on the first diverter pipes, extending through the side walls of the culture tank into the interior. A feeding mechanism is installed on the upper side of the culture tank to improve shrimp breeding survival and yield. This solution uses temperature regulation to influence the culture environment, supplemented by mechanized feeding to meet user requirements. This system is a factory-based breeding system that does not simulate the effects of multiple environmental conditions on the cultured animals. Its simple structure makes it unsuitable for conducting multiple group experiments in laboratory settings. Summary of the Invention

[0004] The utility model provides a shrimp breeding experimental box, comprising a box body, wherein the box body is divided into a plurality of independent small pools; for any small pool:

[0005] A drain is installed at the bottom of the small pool, and there is a water valve on the pipe below the drain; a dissolved oxygen meter electrode holder and a temperature sensor electrode are installed on the side wall of the small pool; the side wall of the small pool is hollow, and a full-spectrum flat-panel light source is installed in the hollow, with the light-emitting surface of the light source facing the pool; the side of the side wall on the light-emitting surface of the light source is transparent, and the other side of the side wall is black (it is best to use a black screen for photography to avoid reflections); the full-spectrum light source simulates light, and the flat-panel structure light source is easy to install on the side wall, and the light is more uniform in the water body.

[0006] An inlet pipe is suspended in the center of the small pond, with its outlet facing downward and extending deep into the pond to prevent shrimp fry from accidentally entering the water supply system. The inlet pipe's inlet is connected in sequence to the water aeration pipe and the water heating pipe. The water aeration pipe is connected to the aerator's outlet via a tee. The water heating pipe is made of metal and is wrapped with a heating tape, commonly used to protect pipes from freezing. The inlet of the heating pipe is connected to the main inlet pipe. This solution achieves functions such as aeration, water heating, water replenishment, and water changes through a single pipe.

[0007] Traditional tank aeration involves injecting air directly into the water through the aerator's outlet. Because shrimp eggs and fry are very small and fragile, air bubbles can easily impact them, causing injury or death. This solution increases the dissolved oxygen in the water before introducing air bubbles into the tank. This allows the air bubbles to be encapsulated by the water, significantly reducing their impact.

[0008] Traditional water tank heating uses electric heating tubes placed directly in the pool water. In small volumes of water, the heating speed is difficult to control, and it is easy to heat up too quickly or heat unevenly.

[0009] There is an isolation net above the drain outlet, which covers the entire cross-section of the small pond to prevent shrimp fry and eggs from being washed into the drain outlet.

[0010] There is a switchable cover on the top of the small pool.

[0011] Furthermore, for any small pond, a support mesh plate for placing shrimp eggs is detachably provided on the isolation net; the support mesh plate is downwardly concave. The shrimp eggs are placed in the support mesh plate and away from the pond bottom to prevent the shrimp eggs from adhering to the pond bottom.

[0012] Furthermore, the bottom of the small pool is funnel-shaped, and the drain outlet is at the bottom of the funnel; the pipes under each small pool are connected to the same drain pipe. The funnel-shaped bottom facilitates flushing and draining of dirt in the pool.

[0013] Furthermore, the bottom surface of the lid is black, and when the lid is closed, it does not reflect light and maintains uniform lighting in the pool.

[0014] Furthermore, agitators are installed on the sidewalls of the small pool. Their rotation axes are parallel to the sidewalls, and their rotation planes are tilted downward. Electric agitators can be installed on each sidewall, or just one. They simulate water flow, and the downward tilt of the rotation plane, in particular, accelerates mixing of cold and hot water, and high and low dissolved oxygen water within the pool.

[0015] Furthermore, the switch of the aerator is an electrically controlled switch, the switch of the water pipe heating belt is an electrically controlled switch, the water inlet of the water inlet heating pipe is connected to an electrically controlled water valve, and the water valve on the pipe below the drain outlet is an electrically controlled water valve.

[0016] The switches for the aerator and heating cable, as well as the valves for the water inlet of the water heater and the drain of the small pool can be manually or electronically controlled. Electronic control is preferred, as these switches and valves can be opened and closed remotely.

[0017] Furthermore, an overflow port is installed on the upper side of the small pond, and a point light source is installed in the hollow space of the side wall at the overflow port. During the latter part of the shrimp hatching period, all healthy shrimp can independently sink, float, and swim horizontally. After hatching, the shrimp are attracted to the overflow port by the light and naturally swim out with the water flow, where they can be collected.

[0018] Furthermore, a shading net is detachably inserted on one side of the light-emitting surface of the full-spectrum flat panel light source. The shading net has one or more layers to better simulate natural light.

[0019] The utility model is suitable for the experiment of shrimp fry breeding and can more comprehensively simulate the growth environment of shrimp fry in a natural state, thus greatly saving the time of shrimp fry breeding experiment. BRIEF DESCRIPTION OF THE DRAWINGS
