Description

Technical Field

[0001] The present invention relates to the technical field of live fish preservation, and particularly to a live preservation device for Bahaba taipingensis Background Art

[0002] Bahaba taipingensis is a rare fish species unique to China, mainly distributed in the Pearl River Estuary in Guangdong Province, the Zhoushan Sea Area in the Hangzhou Bay of Zhejiang Province, and the Quanzhou Bay Sea Area in Fujian Province. In recent years, due to the deterioration of the water environment and excessive illegal fishing, the number of wild Bahaba taipingensis has decreased sharply and it has now been listed as an extremely endangered species. Therefore, conducting scientific research on wild Bahaba taipingensis after fishing can provide important insights and guidance for the artificial breeding of Bahaba taipingensis and the protection of the marine ecological environment.

[0003] However, due to the huge differences between the living sea area of wild Bahaba taipingensis and the land environment, such as pressure, temperature, oxygen content, etc., the problem of keeping wild Bahaba taipingensis alive after fishing is a complex and challenging task. At present, people mainly use technical methods such as anhydrous preservation, oxygenation, low temperature or drug preservation to process and transport live fish. However, these methods generally have problems such as inaccurate temperature control, poor water quality management, unstable oxygen and pressure supply, etc. Moreover, for the live preservation and transportation of live fish caught from the deep sea, due to the complex and changeable environmental conditions on the sea surface, live fish may be affected by vibration, bumping and noise during transportation, and Bahaba taipingensis is extremely sensitive to noise, which all increase the mortality rate of live fish during transportation and cause losses.

[0004] Therefore, developing a live preservation device that can maintain the live state of Bahaba taipingensis after deep-sea fishing is of great significance for improving the survival rate of Bahaba taipingensis after fishing. Summary of the Invention

To achieve the above object, the present invention adopts the following technical solutions: A live preservation device for Bahaba taipingensis, characterized in that: it includes an upper cover, with injection-molded integrated handles on both sides of the upper cover, a solar panel installed on the top inclined plane, and the upper cover is connected to the transportation box through a hinge; a fish inlet is opened at the center of the top of the transportation box, and the fish inlet is rotatably connected to a sealing cover through a rubber sealing ring; a water inlet and outlet is installed on one side of the bottom of the transportation box, and movable casters are connected to the four corners of the bottom through braking devices; a display panel, a control panel and a glass observation window are jointly installed on the front of the transportation box; the top of the outside of the glass observation window is connected to the upper side of the solar panel through a hinge; the fish tank is tightly connected to the top, front and base of the transportation box respectively; an air diffuser pipe is installed inside the fish tank, and a temperature sensor, a pressure sensor and a dissolved oxygen sensor are respectively arranged at the bottom, and a heat preservation layer is arranged around the outside of the fish tank; air inlet and outlet openings are respectively arranged at the bottom of the heat preservation layer and are connected to a water pump heat exchange system through a connecting pipe; an internal water inlet and outlet is arranged at the bottom of the fish tank and is connected to a pressurized circulation filtration system through a stainless steel pipe; the air diffuser pipe is connected to an oxygen pump through an oxygen pipe; a shock-absorbing and sound-insulating layer is arranged between the fish tank and the side wall of the transportation box; the solar panel is connected to a storage battery and an inverter; the temperature sensor, the dissolved oxygen sensor, the pressure sensor, the water pump heat exchange system, the pressurized circulation filtration system, the oxygen pump, the display panel and the control panel are all connected to a control system.

[0006] Further, the volume of the device is 4m×2m×3m; the height of the upper cover is 0.5m; the height of the transportation box is 2.5m; the fish inlet is a circular opening with a diameter of 1m.

[0007] Further, the solar panel is a monocrystalline silicon solar panel with a conversion efficiency ≥20% and a rated power of 55W; the storage battery is a lithium iron phosphate battery pack with a capacity of 1000Ah; the inverter is a pure sine wave inverter with a conversion efficiency ≥90%.

[0008] Further, the control range of the temperature sensor is 0-30°C, and the temperature measurement accuracy is ±0.1°C; the control range of the pressure sensor is 0-1Mpa, and the accuracy is ±0.5%FS; the measurement range of the dissolved oxygen sensor is 0-20mg / L, and the accuracy is ±0.1mg / L.

[0009] Further, the pressurized circulation filtration system includes components such as a booster pump, a circulation water pump, a filter, an ultraviolet sterilization device, etc.

[0010] Further, the flow velocity of the water promoted by the pressurized circulation filtration system is less than or equal to 3m / s.

[0011] Further, the oxygen production purity of the oxygen pump is ≥90%, and the oxygen production amount is 5L / min; a check valve is installed on the air pipe connecting the oxygen pump and the tube type air diffuser pipe.

[0012] Furthermore, before the bahaba taipingensis enters, the control system needs to maintain the dissolved oxygen content in the fish tank at 6 mg / L ± 1 mg / L and the temperature at 10 °C ± 1 °C. After the bahaba taipingensis enters, the pressure is gradually maintained at 0.6 MPa ± 0.01 Mpa, and the rising speed is 0.01 Mpa / min.

[0013] Furthermore, before the bahaba taipingensis enters, 2000 g - 4000 g of sodium carboxymethylcellulose needs to be added to the fish tank in the bahaba taipingensis preservation device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In the bahaba taipingensis preservation device prepared by the present invention, a shock-absorbing and sound-insulating layer is arranged by using a novel sound-absorbing board and a porous ACF bionic cartilage metamaterial to absorb and disperse the impact and noise generated by external factors such as the hull, engine, and waves, thereby maintaining the relative stability of the device and the quiet internal environment state.

[0016] (2) The bahaba taipingensis preservation device prepared by the present invention promotes the rotation of water flow through a pressurized circulation filtration system, and the flow rate is controlled below 3 m / s to avoid the formation of turbulence and reduce the formation of foam in water. On the premise of ensuring the survival of bahaba taipingensis as much as possible, by gradually raising the pressure to the highest and controlling the temperature to the lowest, the formation of foam is further reduced. Finally, a certain proportion of sodium carboxymethylcellulose is added to the fish tank and dispersed in the whole water body under the action of the water circulation system. Under the above combined action, the generation of bubbles in water is minimized to avoid the impact of the noise caused by frequent bubble rupture on bahaba taipingensis.

[0017] (3) The bahaba taipingensis preservation device prepared by the present invention takes the controller as the core, and by integrating a temperature sensor, a dissolved oxygen sensor, and a pressure sensor into the same system, the synchronous monitoring of three key parameters of temperature, oxygen concentration, and pressure is realized. And the integrated system can automatically adjust parameters such as temperature, oxygen concentration, and pressure according to the data monitored in real time, realizing the precise control of the simulated living environment of bahaba taipingensis in the fish tank, thereby improving the survival rate of bahaba taipingensis after fishing.

It should be understood that after reading the content of the present invention, those skilled in the art make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0019] As Figure 1 、 2 、as shown in FIG. 3, a live preservation device for Bahaba taipingensis includes an upper cover (100). On both sides of the top of the upper cover (100), an integrated handle (110) is fixed by welding, which is convenient for flipping the upper cover (100). A high-density polyethylene bracket is fixed in the center of the top of the upper cover (100), and a single-crystalline silicon energy storage solar photovoltaic panel (120) is placed in the bracket to ensure the stability and suitability of the tilt angle of the photovoltaic panel during use, so as to maximize the sunlight irradiation.

[0020] Four movable casters (230) are installed at the four corners on the outer side of the bottom of the transport box (200) so that the transport box (200) can be moved for transportation, and a water inlet and outlet (220) is installed on one outer side. An inlet for fish (210) with a diameter of 1 m is opened at the top of the transport box. A spiral rubber sealing ring (211) is installed at the rim of the inlet for fish (210). During use, the handle (110) on the sealing cover (212) is rotated and screwed to tightly connect the sealing cover (212) with the rubber ring (211) to ensure the tightness of the fish box (300) during use. A display panel (240) and a control panel (250) are arranged on the front of the transport box (200), both of which are electrically connected to the control system (270), and can set the relevant parameters of the growth environment of Bahaba taipingensis and react in real time to the relevant indicators such as the temperature, pressure and dissolved oxygen in the fish box (300). A glass observation window (260) is also installed on the front, and the activity state of the Bahaba taipingensis in the fish box (300) can be observed in real time through the glass observation window (260). A solar panel (120) that can be flipped is connected to one side of the glass observation window (260) through a hinge. The solar panel (120) is flipped down daily to cover the glass observation window (260), which can create a shaded and light-blocked living environment for Bahaba taipingensis.

[0021] The fish box (300) is located inside the transport box (200) and is used for the live preservation and growth of Bahaba taipingensis after fishing. The fish box (300) has a double-layer structure, and a 1.6-cm water injection cavity is arranged between the two layers of glass as a heat preservation layer (350), which can maintain the stability of the water temperature inside the fish box (300). A dissolved oxygen sensor (340), a pressure sensor (330) and a temperature sensor (320) are arranged on one inner wall side of the fish box (300), and are respectively electrically connected to the control system (270). The dissolved oxygen sensor (340), the pressure sensor (330) and the temperature sensor (320) are respectively used to detect the oxygen content, pressure and temperature in the fish box in real time, so as to accurately track and control the internal environment of the fish box. An aeration pipe (310) is installed on one side of the fish box (300) and is connected to an oxygen pump (283) through a trachea with a check valve to prevent the water in the fish box from flowing back and ensure the stability of the dissolved oxygen in the living environment of Bahaba taipingensis. An internal water inlet and outlet is arranged at the inner bottom, and the water inlet and outlet is connected to a pressurized circulation filtration system (282) through a steel pipe. After being pressurized by a booster pump, the pressurized seawater is introduced into the water circulation system through a connecting pipe, and the water quality is circulated and purified and then flows back into the fish box (300) through the water inlet. The outer side of the fish box (300) is filled with a shock-absorbing and sound-insulating layer (400) using porous polypropylene plastic foam material and a new type of sound-absorbing board to reduce the impact of violent shaking and noise during transportation on Bahaba taipingensis.

[0022] First, 3000 g of sodium carboxymethyl cellulose is added to the fish box.

[0023] The water pump heat exchange system (281), the pressurized circulation filtration system (282), and the oxygen pump (283) are all electrically connected to the control system (270). The control system (270) compares the values detected by the dissolved oxygen sensor (340), the pressure sensor (330), and the temperature sensor (320) with the preset values, and controls the operation of the water pump heat exchange system (281), the pressurized circulation filtration system (282), and the oxygen pump (283) to maintain the dissolved oxygen in the fish tank (300) at 6 mg / L ± 1 mg / L, the temperature at 10 °C ± 1 °C, the flow rate of the water flow at 2.5 m / s, and the oxygen production at 5 L / min, so as to create conditions similar to the living environment of wild Bahaba taipingensis. Subsequently, the Bahaba taipingensis that meet the regulations are placed in the fish tank. If the specification is less than 500 g / tail, the number of Bahaba taipingensis is less than or equal to 16 tails. If the specification is greater than 500 g / tail, the number of Bahaba taipingensis is less than or equal to 8 tails. After the Bahaba taipingensis enter, the pressure is gradually maintained at 0.6 MPa ± 0.01 Mpa, and the lifting speed is 0.01 Mpa / min.
