The refracted light in the light guide fiber core 72 can pass through the light-transmitting round sheets from the inside of the end sleeve 71 and the outer sleeve 7, so as to realize the uniform irradiation of sunlight on the microalgae.

[0056] The bottom of the gas collecting hood 51 is fixedly connected with a connecting bracket 52. The upper end of the barrel 5 is fixedly connected with an upper cover 3.

[0060] It should be noted that the solar light source collection system 1 can be selected as a mature device on the market. In actual use, the solar light source collection system 1 can accurately transmit sunlight to the inside of the conductive optical fiber 11.

[0062] In actual use, the excess bubbles in the barrel 5 can be collected into the inside of the defoaming structure 6. The defoaming device can be selected as a mature device on the market. In this document, the function is to realize gas-liquid separation. The separated microalgae culture liquid can be conveyed into the inside of the gas collecting hopper 51 by the liquid discharge pump 62, so as to realize the discharge of the excess microalgae culture liquid by the liquid discharge pump 62.

[0063] Working principle: in the actual use process, the Venturi nanobubble generator 54 can transport bubbles to the inside of the barrel 5, while the liquid delivery pump 53 can transport the microalgae maintenance liquid to the inside of the Venturi nanobubble generator 54, the microalgae maintenance liquid can be mixed with the bubbles and enter the inside of the gas collecting bell 51, which can realize uniform aeration of the inside of the barrel 5, realize the propagation and growth of microalgae in the inside of the barrel 5, and the thermometer 4 can monitor the water temperature in the inside of the barrel 5 in real time during use, facilitating the staff to control the temperature of the microalgae growth;

Finally, the reflected light can penetrate the light-transmitting piece 86 and irradiate on the bubbles in the barrel 5.

[0066] Because the protruding piece 82 protrudes on the sleeve shell 8, the bubbles in the inside of the barrel 5 can be cut, which can realize cutting of large bubbles in the inside of the barrel 5 into small bubbles, improve the refraction probability of the bubbles to the light, and at the same time, the bubbles can also drive the microalgae to surge upward in the inside of the barrel 5, which can realize distribution of the broken bubbles around the microalgae and realize stable growth of the microalgae in the inside of the barrel 5.
