[0024] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in combination with the drawings. Only this statement, the up, down, left, right, front, back, inside, outside and other directions of the utility model appearing or about to appear in the text of the utility model, only with the drawings of the utility model as the base, it is not the specific limitation of the utility model.

[0025] The microalgae culture device provided by the utility model can make the light source assembly 3 output the optimal growth light for the microalgae, so as to meet the different light requirements of the microalgae in different growth stages and promote the growth of the microalgae. Meanwhile, the process of culturing the microalgae is controlled by the control box according to the detection data of the algae liquid detection piece, without manual intervention, so that the reliability and stability of the light adjustment are effectively improved.

[0026] In one specific embodiment of the utility model, as shown in Figure 1 The microalgae culture device includes a culture rack 1 and a control box, the culture rack 1 is provided with multiple culture layers 11, each culture layer 11 is provided with a culture assembly 2, and the culture assembly 2 is suitable for filling culture liquid to provide a growth environment for the microalgae. Each culture layer 11 is provided with a light source assembly 3, and the light source assembly 3 is located above the culture assembly 2, and the light source assembly 3 is electrically connected with the control box. The culture assembly 2 is provided with an algae liquid detection piece, the algae liquid detection piece is connected with the control box, and the algae liquid detection piece is used for detecting the growth state and light environment of the microalgae in the culture assembly 2.

[0027] The microalgae cultivation device provided in this embodiment utilizes a light source component 3 above the cultivation component 2 to provide illumination for the microalgae within the cultivation component 2, thereby culturing the microalgae. Simultaneously, an algal solution detection device within the cultivation component 2 monitors the growth status and light environment of the microalgae in real time. When the control box receives real-time detection data from the algal solution detection device, it adjusts the light intensity, color temperature, frequency, and other illumination parameters of the light source component 3 based on the data. This ensures that the light source component 3 outputs the optimal growth illumination for the microalgae, meeting the different illumination requirements at various growth stages and promoting microalgae growth. Furthermore, the entire microalgae cultivation process is controlled by the control box based on the detection data from the algal solution detection device, requiring no manual intervention and effectively improving the reliability and stability of illumination regulation.

[0028] Specifically, the algal solution detection device can be a cyanobacteria sensor to monitor the growth status of microalgae in the culture medium. Of course, the algal solution detection device is not limited to cyanobacteria sensors; it can also be a chlorophyll a sensor or other algal solution sensors.

[0029] It should be noted that, in addition to controlling the illumination parameters of the light source component 3 through the real-time detection data of the algae liquid detection device, the control box can also monitor and adjust environmental parameters such as temperature and humidity in the culture layer 11, as well as parameters such as pH value of the culture medium in the culture component 2. Specifically, this can be achieved by setting corresponding sensors in the culture layer 11 and the culture component 2, which will not be elaborated here.

[0030] Among them, such as Figure 1 As shown, the cultivation component 2 includes multiple culture dishes 21, which are arranged at intervals in the cultivation layer 11. Each culture dish 21 is equipped with an algal solution detection device. Therefore, when cultivating microalgae using multiple culture dishes 21, each culture dish 21 is cultivated independently, facilitating comparative experiments on the microalgae cultivation environment. The growth status of microalgae in each culture dish 21 is monitored by the corresponding algal solution detection device. By comparing the growth status of microalgae in multiple culture dishes 21 across the multi-layer cultivation layer 11, the growth habits and physiological characteristics of microalgae can be understood, allowing for the determination of the most favorable combination of conditions for microalgae growth, the optimal light intensity for microalgae cultivation, and effectively improving the efficiency of microalgae cultivation.

[0031] For example, in this embodiment, the culture rack 1 is provided with three culture layers 11, and 12 culture vessels 21 are arranged in each culture layer 11. When culturing microalgae, the initial light environment of different culture layers 11 can be set to be different, and different culture medium parameters can be set in the culture vessels 21 of the same layer, so as to conduct a comparative experiment on the microalgae culture environment and determine the optimal combination of conditions for microalgae growth.

[0032] Among them, such asFigure 1 As shown, the culture shelf 1 comprises a top plate 12, a plurality of vertical rods 13 and a plurality of support plates 14, the top plate 12 and the plurality of support plates 14 are arranged in parallel, and the top plate 12 and the support plates 14 are connected by the vertical rods 13, the number of layers of the culture layer 11 is equal to the number of the support plates 14, so as to form a culture shelf by combining the top plate 12, the vertical rods 13 and the support plates 14, to provide a support structure for the culture vessel 21, and to improve the convenience of microalgae culture.

[0033] The light source assembly 3 comprises a plurality of lamp groups 31, one of which is arranged on the top plate 12, and the rest are arranged on the side of the support plate 14 away from the top plate 12, and the culture vessel 21 is arranged on the side of each support plate 14 facing the top plate 12.

[0034] Further, when the support plate 14 separates different culture layers 11, the support plate 14 can separate the light environment of the adjacent two culture layers 11 to a certain extent, so that each group of lamp groups 31 can only affect the light environment of the culture layer 11 where it is located, and avoid the light environment of the adjacent two culture layers 11 affecting each other, so as to ensure that the optimal light environment provided by the lamp group 31 of each culture layer 11 will not be destroyed, and effectively guarantee the culture efficiency of microalgae.

[0035] The surface of the support plate 14 is paved with a light-reflecting piece, so as to reflect the light of the lamp group 31 irradiated on the support plate 14 back into the culture layer 11, thereby realizing secondary utilization of light, and effectively improving the utilization rate of light energy. The light-reflecting piece is preferably a light-reflecting film or a light-reflecting cloth, so as to further improve the light-reflecting performance of the support plate and guarantee the secondary utilization of light energy.

[0036] Specifically, a plurality of lamps can be arranged in one lamp group 31, and the plurality of lamps are uniformly arranged above the culture vessel 21. Preferably, 5 lamps are arranged in each culture layer 11.

[0037] Further, a light-blocking piece is arranged between any two adjacent vertical rods 13. Specifically, the light-blocking piece can be a light-blocking cloth or a light-blocking gauze, the edges of the light-blocking cloth or the light-blocking gauze are provided with clips or ropes, and the light-blocking cloth or the light-blocking gauze is connected with the vertical rod 13 by the clips or the ropes. The light-blocking piece further separates the adjacent two culture layers 11, and further ensures that the light environment of the adjacent two culture layers 11 will not affect each other, thereby further ensuring that the optimal light environment of each culture layer 11 is independent and not affected.

[0038] In the embodiment of the utility model, in the microalgae culture process, the microalgae will consume the nutrient substance in the culture solution continuously, and produce some metabolic products and harmful substances, which will affect the growth environment of the microalgae, and with the continuous proliferation of the microalgae, the demand for nutrient substance will also increase. In order to ensure that the microalgae can grow and reproduce under the best conditions, it is necessary to replenish the culture solution in the culture vessel 21. In order to replenish the culture solution conveniently, as shown in the figure, the delivery pipeline 15 is arranged on each culture layer 11, and the delivery pipelines 15 between adjacent two culture layers 11 are communicated with each other, and the culture vessel 21 is communicated with the delivery pipeline 15 through the connecting pipe 22. Figure 1

[0039] It can be understood that the control box can be provided with a peristaltic pump, and the delivery pipeline 15 is communicated with the external culture solution source through the peristaltic pump. When it is necessary to replenish the culture solution in the culture vessel 21, the peristaltic pump in the control box can be driven to operate, so as to deliver the culture solution from the culture solution source to the delivery pipeline 15, and replenish the culture solution in the culture vessel 21 through the delivery pipeline 15 and the connecting pipe 22, so as to provide nutrient substance for the microalgae, dilute the harmful substances in the culture vessel 21, reduce the negative influence on the growth of the microalgae, and ensure to provide a stable growth environment for the microalgae.

[0040] The inside of the culture vessel 21 is provided with a liquid level meter, the liquid level meter is connected with the control box, and the liquid level meter is used for detecting the liquid level of the culture solution in the culture vessel 21. Then the liquid level meter can be used for monitoring the liquid level of the culture solution in the culture vessel 21, when the liquid level of the culture solution drops to a certain height, the liquid level meter is used for feeding back the control box to operate, so that the control box can drive the peristaltic pump to pump the culture solution to the delivery pipeline 15 and the connecting pipe 22, so as to supplement the culture solution in the culture vessel 21. When the liquid level of the culture solution in the culture vessel 21 reaches a certain height, the liquid level meter is also used for feeding back the control box to stop operating, so as to stop the delivery of the culture solution.

[0041] Therefore, by detecting the liquid level of the culture solution by the liquid level meter, it can be ensured that the liquid level of the culture solution in the culture vessel 21 maintains a certain height, so as to ensure that the culture solution in the culture vessel 21 is sufficient, and then the growth environment of the microalgae is stable.

[0042] Specifically, the liquid level meter is preferably a liquid level sensor.

[0043] ​Wherein, when the culture solution is replenished, the original growth environment of the microalgae needs to be avoided from being destroyed, and therefore the flow of the culture solution input into the culture vessel 21 needs to be controlled. In order to control the flow of the culture solution, the connecting pipe 22 is provided with a flow meter connected with the control box, and the flow meter is used to detect the flow of the culture solution input into the culture vessel 21. Further, the flow of the input conveying pipeline 15 can be controlled by the flow detection data of the flow meter, so as to adjust the flow of the culture solution input into the culture vessel 21. When the flow meter detects that the flow of the culture solution input into the culture vessel 21 is too large, the flow of the input conveying pipeline 15 can be controlled by the control box to reduce the flow of the culture solution input into the culture vessel 21; and when the flow meter detects that the flow of the culture solution input into the culture vessel 21 is too small, the flow of the input conveying pipeline 15 can be controlled by the control box to increase the flow of the culture solution input into the culture vessel 21.

[0044] Specifically, the flow meter is preferably a flow sensor.

[0045] Further, the connecting pipe 22 is connected with the conveying pipeline 15 through a flow control valve, so as to control the flow of the culture solution input into the corresponding culture vessel 21 through the flow control valve of each connecting pipe 22, to control the flow of the culture solution input into each culture vessel 21, and to further ensure that the culture solution is uniformly distributed in each culture vessel 21, so as to avoid that the concentration of the culture solution in a local culture vessel 21 is too high or too low, and to ensure that the growth environment of the microalgae in each culture vessel 21 is stable.

[0046] In another embodiment of the utility model, as shown in Figure 2 The microalgae culture device further comprises a fixing assembly 4, and the culture vessel 21 is installed on the culture layer 11 through the fixing assembly 4. Specifically, the fixing assembly 4 comprises a fixing base 41 arranged at the bottom of the culture layer 11, and the fixing base 41 is formed with an installation slot 42, and each culture vessel 21 is correspondingly inserted into one of the installation slots 42. One culture vessel 21 is correspondingly installed in the installation slot 42 of the fixing base 41, so as to increase the installation stability of the culture vessel 21 in the culture layer 11, and to ensure the growth environment of the microalgae, and to ensure the culture efficiency of the microalgae.

[0047] Further, as shown in Figure 2 The fixing assembly 4 further comprises an installation plate 43 arranged at the middle part of the culture layer 11, and the installation plate 43 is formed with a plurality of limiting holes 44, and each culture vessel 21 is inserted into one of the limiting holes 44, so as to further limit the culture vessel 21 by the limiting holes 44 of the installation plate 43, to further enhance the fixing effect of the culture layer 11 on the culture vessel 21, and to further increase the installation stability of the culture vessel 21.

[0048] The above is the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements also as the protection scope of the present application.
