[0027] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will combine examples to further detail the utility model. The additional aspects and advantages of the utility model will be partly given in the following description, some will become obvious from the following description, or will be known by the practice of the utility model. It should be understood that the following description is only used to explain the utility model, and is not used to limit the utility model.

[0028] The specific embodiments of the utility model will be detailed below.

[0029] Please refer to Figures 1-4 The embodiment provides a Porphyra haitanensis thallus culture device convenient for water changing and cleaning, which comprises a culture jar 1, a jar cover 2, an aeration pipe 4 horizontally fixed and penetratedly installed on the jar cover 2, an illumination pipe 5, a water feeding pipe 6 and a water pumping pipe 7, two groups of water pumps 8 located outside the culture jar 1 and a jar wall anti-pollution assembly arranged on the culture jar 1.

[0030] In the embodiment, the Porphyra haitanensis thallus seedlings grow into longer thalli in the culture device. A rubber sealing ring 3 is fixedly installed on the jar cover 2, and when the jar cover 2 is arranged on the culture jar 1, the rubber sealing ring 3 is filled between the contact surface of the jar cover 2 and the culture jar 1. In the embodiment, the rubber sealing ring 3 is used to improve the sealing performance of the jar cover 2 arranged on the culture jar 1, so that the purpose of preventing the external environment from polluting the culture environment in the jar is achieved.

[0031] The aeration pipe 4 is perpendicular to the jar cover 2, a light supplementing lamp is fixedly installed in the illumination pipe 5, and the end of the illumination pipe 5 immersed in the culture water body is of a closed structure. The light supplementing lamp in the embodiment is taken as an example to be described, and the light supplementing lamp is used to meet the light supplementing requirement of the Porphyra haitanensis thallus growth in a light-dark cycle mode of 12h:12h. The purpose of arranging the aeration pipe 4 is to charge the culture water body, so as to create suitable growth conditions for the Porphyra haitanensis thallus.

[0032] The water outlet end of the water feeding pipe 6 and the water inlet end of the water pumping pipe 7 are arranged close to the jar bottom of the culture jar 1, and a filter screen is detachably arranged at the water inlet end of the water pumping pipe 7, so as to prevent the Porphyra haitanensis thallus seedlings from being pumped away during water changing. In the embodiment, the water feeding pipe 6 is used to feed fresh seawater and nutrient salt, and the water outlet end of the water feeding pipe 6 is arranged close to the jar bottom, so as to empty the water body in the jar as much as possible. The water inlet end of the water feeding pipe 6 is fixedly connected to the water outlet of one group of water pumps 8, and the water outlet end of the water pumping pipe 7 is fixedly connected to the water inlet of the remaining one group of water pumps 8.

[0033] The water pump 8 is provided with a digital timer. According to the planned water replacement period and cleaning frequency, the operation period and operation time of the water pump 8 are set through the digital timer, so as to achieve the purpose of timed water replacement. In order to better control the water quality, the culture device of the embodiment can be provided with a water quality sensor (not shown in the figure) on the cylinder cover 2. The detection end of the water quality sensor extends into the water body, which plays a role in real-time monitoring of the water quality of the culture water in the cylinder, and further ensures that the water quality meets the standard during culture. Here, no further description is given.

[0034] The cylinder wall anti-pollution assembly includes at least three layers of protective films 9 laid between the cylinder wall and the bottom of the culture cylinder 1, a traceless adhesive layer 10 fixedly installed on the corresponding protective film 9, and a tear line 11 printed on the corresponding protective film 9. The traceless adhesive layer 10 is located on the surface of the protective film 9 and is arranged close to the cylinder wall of the culture cylinder 1. The adjacent two layers of protective films 9 are connected by the traceless adhesive layer 10. The innermost layer of protective film 9 is connected to the cylinder wall of the culture cylinder 1 by the traceless adhesive layer 10.

[0035] The culture cylinder 1 has a cylindrical structure. The cylinder wall anti-pollution assembly of the embodiment is shaped to match the structure of the culture cylinder 1 and covers the entire cylinder wall. The protective film 9 can be torn off, and the tear line 11 serves as a marker. The corresponding protective film 9 can be conveniently torn off with the help of the tear line 11. Moreover, the film replacement process is semi-automatic, which avoids cross contamination or improper contact between the films and ensures the effectiveness of each layer of film. During each water replacement, a layer of protective film 9 is torn off. After the current layer of contaminated protective film 9 is torn off, a new clean protective film 9 is exposed. Therefore, the culture cylinder 1 does not need to be cleaned, and the cylinder wall can also be kept clean, which simplifies the process of manual cleaning of the cylinder. It should be noted that the protective film 9 is transparent in color, which facilitates the observation of the culture situation in the cylinder. The embodiment is described by taking eight protective films 9 as an example. The film is replaced every three to four days to meet the culture needs for one month. After one month, new films are added or a new culture device is used for culture.

[0036] When the culture device of the embodiment reaches the water replacement period, the water replacement and cleaning process is as follows:

[0037] First, the water pump 8 connected to the water suction pipe 7 is operated to drain the old water in the culture cylinder 1.

[0038] Next, the cylinder cover 2 is removed, the current contaminated protective film 9 is torn off, and a new protective film 9 is exposed. During the film tearing process, the leaf-like bodies are first concentrated on the side away from the tear line 11. The film and the leaf-like bodies inside are taken out during the tearing process. Then, the leaf-like bodies are transferred to the new protective film 9.

[0039] Finally, the cylinder cover 2 is put on, and the water pump 8 connected to the water filling pipe 6 is operated to send new water into the culture cylinder 1.

[0040] In summary, the culture device of the embodiment has the following advantages: the water can be replaced at a fixed time, the manual operation is reduced, and the cylinder wall can be kept clean by regularly replacing the membrane.

[0041] The preferred embodiments disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details and do not limit the utility model to the specific embodiments described. Obviously, many modifications and changes can be made according to the content of the specification. The specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that the technicians in the technical field can well understand and use the utility model. The utility model is limited by the claims and the entire scope and equivalents thereof.
