Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0030] See attached Figures 1-2 As shown, this embodiment provides an electrical stimulation culture device for microalgae, including: a cabin 1, a liquid delivery pump 3, a transparent serpentine tube 14, a three-way tube 9, a wire 10, a spectrum carbon rod 11, a carbon rod connector 12, a DC power supply 13 and a fluorescent lamp 17, wherein the transparent serpentine tube 14 is layered on a fixing frame 4 along the longitudinal direction, and each layer is provided with a fluorescent lamp 17; specifically, the fixing frame 4 is provided with multiple groups of placement rods 41 along the longitudinal direction, and the transparent serpentine tube 14 and the fluorescent lamp 17 are placed on each layer of the placement rods 41. In this embodiment, the transparent serpentine tube 14 is made of glass.

[0031] Among them, the transparent serpentine tube 14 includes multiple groups of transparent straight tubes 141 and transverse U-shaped tubes 142. The multiple groups of transparent straight tubes 141 are arranged in parallel, and adjacent transparent straight tubes 141 are connected by transverse U-shaped tubes 142. Fluorescent lamps 17 are arranged between adjacent transparent straight tubes 141 on the same layer to provide light for the microalgae in the transparent serpentine tube 14.

[0032] The liquid inlet and liquid outlet ends of the upper and lower adjacent transparent serpentine tubes 14 are connected via a longitudinal U-shaped tube 15; specifically, the liquid outlet end of the lower transparent serpentine tube 14 is connected to the liquid inlet end of the upper transparent serpentine tube 14 via the longitudinal U-shaped tube 15, and the liquid outlet end of the top transparent serpentine tube 14 is connected to the feed pipe 103 at the top of the cabin 1 via a connecting tube 16, and the microalgae mixed liquid in the top transparent serpentine tube 14 flows into the feed pipe 103 via the connecting tube 16 and flows back into the cabin 1.

[0033] The discharge pipe 102 at the bottom of the cabin 1 is connected to the input end of the liquid delivery pump 3 through a pipeline, and the output end of the liquid delivery pump 3 is connected to the three-way pipe 9 through a pipeline. The side opening of the three-way pipe 9 is sealed with a cover 91, and the cover 91 is threadedly connected to the side opening of the three-way pipe 9, and the thread can be further wrapped with a raw tape to improve its connection sealing. The other end of the three-way pipe 9 is connected to the liquid inlet end of the bottom transparent serpentine pipe 14 through a pipeline and a longitudinal U-shaped pipe 15. When working, the liquid delivery pump 3 operates to input the microalgae mixed liquid in the cabin 1 into the bottom transparent serpentine pipe 14, and the bottom transparent serpentine pipe 14 then transports the microalgae mixed liquid to each layer of transparent serpentine pipes 14 through the longitudinal U-shaped pipe 15. Finally, the microalgae mixed liquid flows into the feed pipe 103 through the connecting pipe 16, and flows back to the cabin 1 to form a cycle.

[0034] In this embodiment, the cabin 1 is mounted on the tripod 2, and a hatch 101 is provided on the top of the cabin 1. When in use, the hatch 101 can be opened to feed materials into the cabin 1. A valve with an adjustable opening is provided on the discharge pipe 102 of the cabin 1, and the user can adjust the valve opening according to needs.

[0035] See attached Figure 1 and 4 As shown, two round holes are provided on the top of the cover 91 for passing the wires 10. One end of the two wires 10 passes through the round holes on the top of the cover 91 and extends into the pipe. The fitting between the wires 10 and the round holes on the top of the cover 91 is sealed by glue to prevent the liquid in the pipe from overflowing. The wires 10 include a copper core and an insulating layer covering the copper core.

[0036] One end of the two wires 10 extending into the pipeline is connected to a spectral carbon rod 11 (6 mm in diameter) respectively. The spectral carbon rod 11 has a low metal impurity content and very stable physical and chemical properties, and will not be corroded to affect its use. The other ends of the two wires 10 are respectively connected to the positive and negative poles of a DC power supply 13 with adjustable voltage. The DC power supply 13 supplies power to the spectral carbon rod 11 through the wire. In this embodiment, the DC power supply 13 uses an adjustable voltage DC power supply. Multiple groups of carbon rod connectors 12 are arranged between the two spectral carbon rods 11 (in this embodiment, three groups of carbon rod connectors 12 are arranged, respectively located in the middle and both ends of the spectral carbon rod 11, and the carbon rod connectors are made of PLA plastic material) to fix the distance between the two spectral carbon rods 11.

[0037] See attached Figure 5 As shown, the carbon rod connector 12 includes a ring 121 and a connecting rod 122. The connecting rod 122 connects the rings 121 at both ends. The rings 121 and the spectral carbon rod 11 are tightly matched. When in use, the spectral carbon rod 11 is inserted into the ring 121 of the carbon rod connector 12 to fix the distance between the two spectral carbon rods 11. In this embodiment, the distance between the two spectral carbon rods 11 is 2 cm.

[0038] When the liquid flows in the tube of the device, since the wire 10 is fixed on the cover 91, the flow of water will drive the spectral carbon rod 11 and the carbon rod connector 12 to move and straighten the wire 10. At the same time, under the action of the water flow, the spectral carbon rod 11 and the carbon rod connector 12 will float up, thereby preventing the spectral carbon rod 11 from sinking to the bottom and affecting the electrical stimulation effect.

[0039] See attached Figure 1 and 3 As shown, the electric stimulation culture device for microalgae in this embodiment also includes a sensor installation tube 5, which is connected to the pipeline system of the electric stimulation culture device for microalgae. Specifically, one end of the sensor installation tube 5 is connected to the feed end of the three-way tube 9, and the other end of the sensor installation tube 5 is connected to the discharge end of the liquid delivery pump 3 through a pipeline.

[0040] Three branch pipes are arranged on the side of the sensor installation tube 5, on which a temperature sensor 6, a pH sensor 7 and a gas delivery pipe 8 are respectively installed. The lower ends of the temperature sensor 6, the pH sensor 7 and the gas delivery pipe 8 are all extended into the sensor installation tube 5, and the gas delivery pipe 8 is connected to an external carbon dioxide supply end. The joints between the temperature sensor 6, the pH sensor 7, the gas delivery pipe 8 and the sensor installation tube 5 are sealed with glue to prevent liquid from overflowing.

[0041] The temperature sensor 6 and the pH sensor 7 are used to detect the pH value and temperature of the microalgae mixed liquid, and the gas delivery pipe 8 is used to input the CO2 gas output from the external carbon dioxide supply end (wherein the carbon dioxide supply end is a titanium dioxide gas tank) into the device pipeline. When the photosynthesis of the microalgae is strong, CO2 gas can be introduced into the pipeline.

[0042] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
