Description

Technical Field

[0001] The present invention relates to an aquaculture technology, and particularly to an experimental breeding device for Rana chensinensis in Northeast China and a using method thereof. Background Art

[0002] The breeding experiment of Rana chensinensis is an essential part of carrying out relevant scientific research. However, during the laboratory breeding process, Rana chensinensis is prone to problems such as escape and death under the influence of various factors, resulting in various losses.

[0003] The current problems are as follows:

[0004] 1) When the juvenile frogs just metamorphose and come ashore. Due to the changes in their morphology and breathing methods, they will have the behavior of coming ashore. If they do not come ashore in time, they will be attacked by other tadpoles and lead to death;

[0005] 2) When the frogs are completely metamorphosed, due to their own habits, they will climb upward along the breeding tank wall, thus promoting their escape behavior;

[0006] 3) The frequent entry and exit of laboratory personnel can also easily frighten the juvenile frogs, resulting in escape or clustered death;

[0007] 4) After Rana chensinensis metamorphoses from tadpoles into juvenile frogs, it is necessary to spray water on the juvenile frogs to prevent their skin from drying out, which will affect breathing and ultimately lead to death. However, too much spraying will cause the juvenile frogs to die due to hypothermia.

[0066] In summary, this embodiment provides an experimental breeding device for Rana dybowskii and its usage method. The experimental breeding device and its usage method are summarized as follows:

[0067] Regarding the experimental breeding device:

[0068] The experimental breeding device mainly consists of a breeding box 1 and a temperature and humidity adjustment device 2 specially configured for the breeding box 1.

[0069] The main body of the breeding box 1 is made of acrylic material.

[0070] A simulated shore board 4 is arranged inside the breeding box 1. The shape of the simulated shore board 4 is similar to the configuration of a springboard used in gymnastics. The simulated shore board 4 has an inclined simulated shore slope, and the inclination angle of the simulated shore slope is set within the range of 15 - 30°.

[0071] The simulated shore board 4 is placed at the inner bottom of the breeding box 1. A small part of the simulated shore slope of the simulated shore board 4 is below the lower design water level line, and most of the simulated shore slope is above the upper design water level line. In this way, when water is injected into the breeding box 1 (the water level is between the lower design water level line and the upper design water level line), a small part of the simulated shore slope is in the water body, and most of the simulated shore slope is separated from the water body.

[0072] A felt 5 is also provided on the simulated bank slope surface of the simulated bank board 4. The simulated bank slope surface of the simulated bank board 4 essentially simulates the scene of the shore of a natural water area. The simulated bank board 4 is used so that the young frogs in the water body can climb out of the water surface by means of the simulated bank slope surface of the simulated bank board 4, thereby simulating the effect of the young frogs coming ashore.

[0073] A combination of a transparent cover plate 31 and an invisible screen window is provided at the upper opening of the breeding box 1.

[0074] Specifically,

[0075] The transparent cover plate 31 is fixedly provided at the upper opening of the breeding box 1. The transparent cover plate 31 covers half of the upper opening of the breeding box 1, while the other half of the upper opening of the breeding box 1 is equipped with the invisible screen window (essentially the combination of the screen curtain box 32 and the cover net 33).

[0076] It should be noted that the invisible screen window is a device of the prior art (also known as "roller screen window" or "reel screen window"), and such a device can be purchased or customized from the market. For example, by using the keyword "invisible screen window" on Taobao.com, a large number of similar products can be retrieved.

[0077] The combination of the transparent cover plate 31 and the invisible screen window essentially constitutes the lid assembly of the entire breeding box 1 (equivalent to the breeding box lid 3 mentioned before). This lid assembly can completely cover the upper opening of the breeding box 1 to prevent the young frogs in the breeding box 1 from escaping.

[0078] More specifically, the lid assembly includes a frame body (square frame). For the convenience of description, this frame body is called the lid frame. The transparent cover plate 31 and the invisible screen window are both assembled and arranged based on this lid frame, thereby constituting the overall lid assembly.

[0079] A buckle switch 34 is also provided for the invisible screen window to facilitate the opening and closing of the invisible screen window.

[0080] It should be noted that the lid assembly is assembled at the upper opening of the breeding box 1 through an existing connecting device 35. Essentially, the lid frame of the lid assembly is assembled at the upper opening of the breeding box 1 through the connecting device 35.

[0081] See Figure 2 , the connecting device 35 is essentially an embedding groove formed by a downward extension of the lid frame. The upper edge of the breeding box 1 is embedded in the embedding groove, thereby realizing the assembly connection between the lid frame and the breeding box 1.

[0082] A drain pipe opening is also provided at the lower part of the breeding box 1, and a drain valve 8 is provided for this drain pipe opening to facilitate the discharge of the water body in the breeding box 1.

[0083] At the upper part of the breeding tank 1, an oxygen pipe orifice 11 is also provided. The function of the oxygen pipe orifice 11 is to put oxygen from an oxygen pump into the water body in the breeding tank 1 through the oxygen pipe orifice 11, and use the oxygen pump to increase the oxygen content in the water body.

[0084] A spray head 25 is provided on the transparent cover plate 31.

[0085] A temperature and humidity sensor 23 and a temperature regulator 24 are provided inside the breeding tank 1. Both are assembled on the inner side wall surface of the breeding tank 1, and both are above the upper design water level line inside the breeding tank 1.

[0086] In this embodiment, the brand model of the temperature and humidity sensor 23 is: rs485 temperature and humidity sensor.

[0087] In this embodiment, the temperature regulator 24 is an electric heater blower, and the specific brand model is: air heater blower CSH8 - F24000.

[0088] It should be noted that in other embodiments, other temperature regulators with both heating and cooling functions can also be used to achieve better temperature regulation effects.

[0089] The temperature and humidity adjustment device 2 mainly includes a water storage device 26. The water storage device 26 has a water outlet pipe orifice, and a manual valve, namely an inlet valve 7, is provided for this water outlet pipe orifice. The water outlet pipe orifice of the water storage device 26 is connected to the spray head 25 on the transparent cover plate 31 mentioned above through a water guide pipe 27 (a water - passing pipeline), and a water pump 6 is provided on the water guide pipe 27. In this way, by opening the inlet valve 7 and turning on the water pump 6, the water in the water storage device 26 can be used and the internal space of the breeding tank 1 can be sprayed with water mist through the spray head 25 to achieve the effect of increasing the air humidity in the breeding tank 1.

[0090] A controller 21 is also provided on the water guide pipe 27. The controller 21 is a device of the prior art. In this embodiment, the brand model of the controller 21 is "microcomputer intelligent temperature and humidity controller, model: K830" (purchased on Taobao, specific connection: https: / / e.tb.cn / h.6WnzWrOpGLywK92?tk=zaFsevPytyZCZ007 「Genuine digital display intelligent high - precision temperature and humidity greenhouse fan breeding, planting, seedling raising temperature control switch instrument」).

[0091] The controller 21 has a temperature and humidity signal input interface, and the previously mentioned temperature and humidity sensor 23 is connected to the temperature and humidity signal input interface through a dedicated signal line.

[0092] The controller 21 has a temperature control signal output interface, and the previously mentioned temperature regulator 24 is connected to the temperature control signal output interface through a dedicated signal line. The controller 21 can control the temperature inside the breeding box 1 by controlling the start and stop operation of the temperature regulator 24.

[0093] In addition, the start and stop of the water pump 6 are also controlled by the controller 21. The controller 21 also has a control interface, and the control interface has a display screen and some operation buttons, such as a controller switch, a key for setting the temperature and humidity range, a heating key, and a humidification start key, etc.

[0094] A control circuit module (including a program that can implement the control process) is set inside the controller 21, and this control circuit module can implement the following control functions:

[0095] Set the temperature control range and humidity control range inside the breeding box 1 on the control interface of the controller 21, and the set data is displayed on the display screen.

[0096] Sense the real-time temperature and humidity inside the breeding box 1 through the temperature and humidity sensor 23, and the real-time temperature and humidity data are displayed on the display screen.

[0097] When the temperature inside the breeding box 1 exceeds the temperature control range, control the temperature regulator 24 or the water pump 6 to start running to adjust the temperature inside the breeding box 1 within the temperature control range, and then control the temperature regulator 24 or the water pump 6 to stop.

[0098] The start and stop operation status of the temperature regulator 24 is displayed on the display screen.

[0099] When the air humidity inside the breeding box 1 exceeds the humidity control range, the controller 21 controls the water pump 6 to start running to make the water conduit 27 flow, so as to control the spray head 25 to spray water mist into the breeding box 1 to increase the air humidity inside the breeding box 1 within the humidity control range, and then control the water pump 6 to stop. The start and stop operation status of the water pump 6 is displayed on the display screen.

[0100] The basic control functions of the control circuit module are as described above.

[0101] The function of the entire temperature and humidity adjustment device 2 is similar to that of a daily household air conditioner, and it can be understood as an "air conditioner" configured for the breeding box 1. Its role is to adjust the air temperature and humidity in the breeding box 1 to facilitate providing a suitable growth environment for the young frogs in the breeding box 1.

[0102] The experimental breeding device of this embodiment has the following advantages:

[0103] 1) A simulated shore board 4 is arranged in the breeding box 1, and after the young frogs in the breeding box 1 metamorphose into adult frogs, they can timely use the simulated shore board 4 to come ashore, thereby preventing the situation where the young frogs gather in the corner and die.

[0104] 2) A transparent cover plate 31 and an invisible screen window are arranged on the breeding box 1. When observing the young frogs in the breeding box 1, it is difficult for the young frogs to jump out from the opening.

[0105] 3) Through the controller 21, it is convenient for the staff to understand the internal environmental conditions of the breeding box 1 in real time and flexibly adjust the temperature and humidity inside the breeding box 1.

[0106] 4) Through the transparent cover plate 31, it is convenient for the staff to observe the situation inside the breeding box 1 at any time, and the invisible screen window can also be opened at any time to handle the young frogs in the breeding box 1.

[0107] 5) A temperature and humidity adjustment device 2 is configured for the breeding box 1, so as to achieve the effects of heat preservation and moisture preservation for the young frogs.

[0108] It should be noted that in this embodiment, the temperature control range is 18 - 22 °C, and the humidity control range is 85 - 100%.
