[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Embodiment 1:

[0024] Refer to Figures 1-3 , a microalgae growth monitoring device, comprising: a detection housing 1. Specifically, the detection housing 1 is a cylindrical light-tight container; a driving motor 2, fixedly connected to the inner bottom wall of the detection housing 1; wherein, the output end of the driving motor 2 is fixedly connected with a detection turntable 201, and the detection turntable 201 divides the upper and lower spaces of the detection housing 1 into a detection chamber 101 and a sewage collection chamber 102; a camera unit 501, slidably connected to the upper part of the detection chamber 101; wherein, the camera unit 501 faces the detection turntable 201, and the camera unit 501 is a CCD camera; a control chamber 4, arranged at the upper end of the detection housing 1; a sampling part, arranged at the side end of the detection housing 1; wherein, the liquid outlet direction of the sampling part faces the detection turntable 201;

[0025] It should be noted that the radius of the detection turntable 201 is slightly smaller than the radius of the detection housing 1, that is, there is a gap between the outer wall of the detection turntable 201 and the inner wall of the detection housing 1, and the detection turntable 201 is designed with a lower middle and a higher edge, which can effectively reduce the influence of centrifugal force on the algal cells in the algal liquid. During the process of spreading the algal liquid, the algal cells can be distributed more evenly, improving the detection accuracy.

[0026] The upper end of the detection housing 1 is fixedly connected with a second electric telescopic rod 5, the camera unit 501 is fixedly installed at the telescopic end of the second electric telescopic rod 5, and a magnifying glass 502 is installed at the shooting end of the camera unit 501.

[0027] The detection housing 1 is fixedly connected with a control chamber 4, and the control chamber 4 is used to control the first electric telescopic rod 303, the second electric telescopic rod 5, the photoelectric sensor 302, and the camera unit 501.

[0028] The sampling part includes: a liquid extraction cylinder 3 fixedly connected to the detection housing 1; a piston plate 301 slidably connected inside the liquid extraction cylinder 3; wherein, an inlet pipe 304 and a drain pipe 305 are arranged inside the liquid extraction cylinder 3. One end of the inlet pipe 304 away from the liquid extraction cylinder 3 communicates with the microalgae cultivation container. One-way components are arranged on both the inlet pipe 304 and the drain pipe 305. The one-way components are used for the liquid extraction cylinder 3 to extract the algal liquid in the microalgae cultivation container to the detection frustum 201.

[0029] A first electric telescopic rod 303 is fixedly connected to the control cabin 4, and the piston plate 301 is fixedly connected to the output end of the first electric telescopic rod 303.

[0030] The one-way component includes an inlet liquid sealing door 3041 and a drain liquid sealing door 3051. The inlet liquid sealing door 3041 is rotatably connected inside the liquid extraction cylinder 3. The inlet liquid sealing door 3041 is used to block the inlet pipe 304. The drain liquid sealing door 3051 is rotatably connected inside the detection cabin 101. The drain liquid sealing door 3051 is used to block the drain pipe 305. Counterweights are arranged at the lower ends of the drain liquid sealing door 3051 and the inlet liquid sealing door 3041. In another embodiment, the one-way component can also adopt a one-way valve. By setting the one-way valve, the flow direction of the algal liquid is from the microalgae cultivation container into the liquid extraction cylinder 3 and then flows to the detection frustum 201.

[0031] Photoelectric sensors 302 are fixedly connected to both the upper and lower side walls of the liquid extraction cylinder 3. Specifically, the photoelectric sensor 302 includes a transmitting end and a receiving end. The transmitting end, the center of the piston plate 301, and the receiving end are on the same straight line.

[0032] A supplementary light 503 is arranged on the inner upper wall of the detection housing 1. When shooting, turning on the supplementary light 503 can improve the shooting effect.

[0033] When using this device, connect the inlet pipe 304 to the microalgae cultivation container. Through the control cabin 4, start the first electric telescopic rod 303. The first electric telescopic rod 303 drives the piston plate 301 to move upward. Under the action of air pressure, the drain liquid sealing door 3051 closes and the inlet liquid sealing door 3041 opens. The algal liquid in the microalgae cultivation container enters the liquid extraction cylinder 3 through the inlet pipe 304. When the piston plate 301 moves upward between the transmitting end and the receiving end, the photoelectric sensor 302 cannot receive the signal and feeds it back to the control cabin 4. At this time, the liquid extraction amount reaches the preset value. The control cabin 4 controls the first electric telescopic rod 303 to drive the piston plate 301 to move downward. Under the action of air pressure, the inlet liquid sealing door 3041 closes and the drain liquid sealing door 3051 opens, so that the algal liquid in the liquid extraction cylinder 3 enters the detection frustum 201 in the detection housing 1 through the drain pipe 305;

[0034] It should be noted that in another embodiment, by adjusting the position of the photoelectric sensor 302, the quantitative sampling amount of the liquid extraction cylinder 3 can be adjusted;

[0035] When the piston plate 301 is located between the photoelectric sensors 302 on the lower side, the algal liquid in the liquid extraction cylinder 3 is drained completely, and the first electric telescopic rod 303 stops moving. At this time, the control cabin 4 controls the driving motor 2 to start and drives the detection turntable 201 to rotate slowly. Under the action of centrifugal force, the algal liquid at the center position of the detection turntable 201 is evenly spread on the detection turntable 201. The supplementary light lamp 503 is turned on for supplementary lighting, and the second electric telescopic rod 5 pushes the camera unit 501 downward to take pictures of the spread algal liquid;

[0036] After taking pictures, the supplementary light lamp 503 is turned off, the camera unit 501 moves upward, and the driving motor 2 accelerates. Under the action of centrifugal force, the algal liquid is discharged into the sewage collection cabin 102 for collection, waiting for the next detection;

[0037] At this time, the control cabin 4 analyzes the photos, obtains and records the RGB data of the algal liquid pictures through image analysis software, analyzes the morphology of the microalgae in the algal liquid pictures through image recognition software, and records the number of damaged microalgae cells and normal microalgae cells, thereby completing the detection of the growth state and growth stage of the microalgae;

[0038] The utility model can quantitatively extract algal liquid, automatically transport the algal liquid to the detection turntable 201, and the liquid extraction volume is convenient to adjust. When taking pictures, it is convenient to spread the algal liquid, which is not easy to damage algal cells, improves the detection accuracy, and is convenient to clean the detection turntable 201 after detection, saving manpower and material resources.

[0039] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the utility model.
