Description

Technical Field

[0001] This application relates to the field of microbiological device technology, and in particular to a Spirulina ecological culture device. Background Technology

[0002] Spirulina is a type of microalgae that is edible and rich in nutrients. It is believed to have benefits such as reducing the toxic side effects of cancer radiotherapy and chemotherapy, improving immune function, and lowering blood lipids. Currently, the mainstream industrial cultivation method for spirulina is shallow pond cultivation, with a water depth of 0.2–0.3 meters. This relies on paddle wheel agitation, natural light, and open-air cultivation. However, shallow ponds require a large area, have low yield per unit area, poor water stability, and are easily affected by the external environment. Therefore, deep pond cultivation has emerged, which is suitable for the ecological cultivation of spirulina in water depths of 0.5–2.0 meters.

[0003] To adapt to deep cultivation, spirulina ecological cultivation equipment adopts an underwater layered lighting design. Typically, lighting modules are suspended horizontally at depths of 0.5 meters, 1.0 meters, 1.5 meters, and 2.0 meters underwater to meet the high-efficiency photosynthetic needs of spirulina. However, with long-term use, algal biofilms will adhere to the outer walls of the lighting modules, affecting the lighting effect and even providing a breeding ground for bacteria, leading to cultivation failure. Summary of the Invention

[0004] This application proposes a Spirulina ecological cultivation device, which has the advantages of a movable module that can effectively rotate along the outer wall of the supplementary lighting module in cooperation with a rotating module, thereby cleaning the supplementary lighting module in a timely and effective manner, enhancing the supplementary lighting effect, and improving the cultivation effect. This device solves the problem that the supplementary lighting module is affected by the light efficiency due to the algal biofilm attached to its outer wall.

[0005] To achieve the above objectives, this application adopts the following technical solution: a Spirulina ecological cultivation device, comprising: The supplementary lighting module is provided in four sets, and the four sets of supplementary lighting modules are arranged in layers inside the pool body; The active module consists of two centrally symmetrical active modules forming a set, and an active module is externally connected to a set of active modules for one supplementary lighting module; A rotating module is provided around each set of supplementary lighting modules, and the rotating module is movably connected to multiple sets of movable modules. The gas replenishment module has two sets of gas replenishment modules inside the pool body, and the two sets of gas replenishment modules are located at the two ends of the light replenishment module. The gas replenishment module includes a support frame and several fixed components, and two fixed components are correspondingly provided for each set of movable modules. The upper half of the fixed component is fixedly connected to the outside of the support frame, and the lower half of the fixed component is movably engaged with the end of the set of movable modules.

[0006] Furthermore, a group of horizontally arranged supplementary lighting modules constitutes a supplementary lighting module, and the supplementary lighting module includes: A protective shell, which horizontally penetrates the pool body; A protective cap is threaded onto the end of the protective shell; The lamp rod is movably sleeved inside the protective shell, and the end of the lamp rod abuts against the inner wall of the protective cap.

[0007] Furthermore, the movable module rotates clockwise, and the movable module includes: The movable arc plate has two movable arc plates, and the movable arc plates are semi-circular rings. The inner wall of the movable arc plate is movably engaged with the outer wall of the supplementary lighting module, and the outer wall of the movable arc plate is provided with a meshing groove and a limiting groove. A movable inclined plate is fixedly connected between the two movable arc plates. The movable inclined plate is inclined and the center line of the movable inclined plate is tangential to the diameter line of the supplementary lighting module. According to the rotation direction of the movable inclined plate, the two sides of the movable inclined plate are divided into the incoming side and the outgoing side. The surface of the movable inclined plate is provided with a thin film coating.

[0008] By designing the angle of the movable inclined plate so that its centerline is tangential to the diameter of the protective shell, the angles formed between the two sides of the movable inclined plate and the wall of the protective shell are different. This not only makes it easier to clean algae biofilm on the incoming side of the movable inclined plate, enhancing the cleaning effect on the protective shell, but also allows the outgoing side of the movable inclined plate to refract and reflect the light emitted by the protective shell, enhancing the supplementary lighting effect and improving the growth efficiency of spirulina.

[0009] Furthermore, the rotating module includes: Each set of supplementary lighting modules is provided with four rotating shafts, and each rotating shaft is movably sleeved on the wall of the pool. A rotating belt is movably sleeved on two rotating shafts located on the same side of the pool body. The inner wall of the rotating belt is fixedly connected with a toothed block, and the rotating belt simultaneously engages with the outer wall of the rotating shaft and the meshing groove of the movable arc plate through the toothed block. A rotating motor is fixedly installed outside the pool body and is movably connected to one of the rotating shafts. The rotating motor drives the rotating shaft to rotate clockwise.

[0010] Furthermore, the support frame is fixedly attached to the pool body. The support frame consists of horizontal and vertical frames, with one horizontal frame positioned above a set of supplementary lighting modules.

[0011] Furthermore, the fixing component includes: A fixed connecting plate is U-shaped, with its upper half movably engaged with the wall of the support frame and its lower half movably engaged with the limiting groove of the movable arc plate. The fixed horizontal plate is two in number, and the top of the two symmetrically arranged fixed connecting plates is spliced ​​and fixed by the fixed horizontal plate. A fixed arc plate is provided inside the two fixed connecting plates, and the lower half of the fixed arc plate is movably engaged with the limiting groove of the movable arc plate. The upper half of the fixed arc plate is fixedly sleeved to one end of the fixed tube, and the other end of the fixed tube is fixedly sleeved to the bottom of the support frame.

[0012] Furthermore, the support frame has a main air passage inside, and the main air passage of the support frame is connected to the air storage tank; The fixed arc plate has a fixed air passage inside, and the fixed air passage is composed of a fixed arc hole and a fixed straight hole, with one fixed arc hole connected to several fixed straight holes; The fixed tube has a branch air passage inside, and one end of the branch air passage is connected to the main air passage of the support frame, and the other end of the branch air passage is connected to the fixed air passage of the fixed arc plate. Both of the movable arc plates have movable air passages inside, and the movable air passages are composed of movable arc holes and movable straight holes. One movable arc hole is connected to several movable straight holes, and the movable straight holes are intermittently aligned with the fixed straight holes. The movable inclined plate has an output air passage inside, and the output air passage is composed of an output horizontal hole and an output vertical hole. One end of the output horizontal hole is connected to the movable air passage, and the other end of the output horizontal hole is connected to several output vertical holes.

[0013] By setting a fixing component at the end of each set of movable modules, and suspending the fixing component on the support frame, the design of the support frame and fixing component can not only enhance the working stability of the supplementary lighting module and movable module, but also deliver carbon dioxide gas to the destination side of the movable inclined plate, so that the carbon dioxide gas can fully contact the spirulina. Since this operation is located on the destination side of the movable inclined plate, that is, in the light refraction and reflection area, it effectively enhances the fixing effect of carbon dioxide gas and further improves the growth efficiency of spirulina.

[0014] Furthermore, the movable inclined plate is provided with: A high-porosity plate is fixedly embedded inside the movable inclined plate at the end of the output gas path, and the high-porosity plate is located on the direction of travel of the movable inclined plate. The auxiliary components are provided on the direction side of the movable inclined plate, and a high-porosity plate is provided between two adjacent auxiliary components.

[0015] Furthermore, the auxiliary components include: An auxiliary rod is provided, wherein the wall surface of the movable inclined plate is provided with a long groove, and the auxiliary rod is movably engaged in the long groove of the movable inclined plate; The auxiliary plate has a cross-sectional shape of a right-angled isosceles triangle, and the right-angled edge of the auxiliary plate is fixedly connected to the middle wall of the auxiliary rod. The surface of the auxiliary plate is provided with a thin film coating. When the side wall of the auxiliary plate is attached to the side wall of the movable inclined plate, the auxiliary plate completely covers the high porosity plate. The auxiliary cap has a short groove on the wall of the movable inclined plate. The external thread of the auxiliary cap is threaded into the short groove of the movable inclined plate, and the internal part of the auxiliary cap is movably connected to the end of the auxiliary rod.

[0016] By setting auxiliary components on the destination side of the movable inclined plate, and placing a high-porosity plate between two adjacent auxiliary components, when carbon dioxide gas passes through the high-porosity plate and is discharged outward, the impact force of carbon dioxide on the auxiliary components is constantly changing because the fixed gas path on the fixed arc plate is intermittently connected to the movable gas path on a set of movable arc plates. In conjunction with the rotation of the movable inclined plate, the auxiliary components are continuously oscillating, thereby effectively enhancing the refraction and reflection effect on the destination side of the movable inclined plate and further improving the growth efficiency of spirulina. In addition, when the movable module stops rotating and the gas supply module stops supplying gas, the movable inclined plate is placed vertically, causing the auxiliary components to block the high-porosity plate, thus protecting the high-porosity plate and extending its service life.

[0017] Furthermore, a set of the aforementioned supplementary lighting modules and their components constitute a working system, and the pool body is also equipped with: A photovoltaic power generation system is installed above the pool body; An aeration and agitation system is arranged at the bottom or on the wall of the tank. A heating system, wherein the heating system is installed in the middle or bottom layer of the pool body; The intelligent control system is electrically connected to the photovoltaic power generation system, the aeration and stirring system, the heating system, and the working system.

[0018] The beneficial effects of this invention are as follows: This application provides a Spirulina ecological cultivation device, which consists of a set of rotating modules arranged around each set of supplemental lighting modules, and a set of movable modules fitted onto each supplemental lighting module, with the movable modules movably connected to the rotating modules. Each supplemental lighting module includes a protective shell, a protective cap, and a lamp rod; each rotating module includes a rotating shaft, a rotating belt, and a rotating motor; and each movable module includes a movable arc plate and a movable inclined plate. When algal biofilm adheres to the outer wall of the protective shell, the rotating shaft and rotating belt are meshed, and the rotating belt and movable arc plate are also meshed. This causes the rotating shaft to drive the rotating belt to rotate cyclically, thereby causing the movable arc plate to rotate and the movable inclined plate to rotate clockwise along the outer wall of the protective shell. This effectively cleans the algal biofilm adhering to the outer wall of the protective shell, ensuring the supplemental lighting effect and improving the cultivation effect.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: A Spirulina ecological cultivation device, such as... Figures 1-2 The system includes a pool body 1, with a conical or sloping bottom and a drain valve. The top of pool body 1 is equipped with a guardrail and inspection port. A photovoltaic power generation system is installed above pool body 1, consisting of photovoltaic modules, a controller, a battery bank, and an inverter. This system converts solar energy into electrical energy, prioritizing power for supplemental lighting, aeration, heating, and control units, and supports photovoltaic complementarity. An aeration and agitation system is located at the bottom or wall of pool body 1, consisting of a high-pressure blower, main pipe, branch pipes, and microporous aeration discs. This system generates rising and horizontal airflow to provide agitation power and oxygenation for the water. To prevent algae settling and promote uniform nutrient distribution, the heating system is installed in the middle or bottom layer of tank 1. It uses an underwater constant temperature heating rod, a waterproof heating membrane, or a heat pump heat exchange unit, which can be coupled with the aeration zone to improve heat exchange efficiency. Its temperature is adjustable from 28 to 35°C and is automatically started and stopped by an intelligent controller. The intelligent control system is electrically connected to the photovoltaic power generation system, aeration and stirring system, heating system, and working system. It can automatically adjust the light intensity, aeration volume, heating power, and supplemental lighting duration, and automatically alarm and protect against low temperature, high temperature, low pressure, and lack of oxygen. In summary, the design of tank 1 effectively achieves land saving and yield increase.

[0023] A working system includes a set of supplementary lighting modules 2 and its components, specifically: like Figures 2-4 The supplementary lighting module 2 has four sets, and the four sets of supplementary lighting modules 2 are arranged in layers inside the pool body 1. Several horizontally arranged supplementary lighting modules 2 constitute a set of supplementary lighting modules 2. The supplementary lighting module 2 includes a protective shell 21, a protective cap 22, and a lamp rod 23, as shown. Figures 9-10 The protective shell 21 horizontally penetrates the pool body 1 and is made of acrylic material with good light transmittance. The end of the protective shell 21 is threaded with a protective cap 22, and a lamp rod 23 is movably sleeved inside the protective shell 21. The end of the lamp rod 23 abuts against the inner wall of the protective cap 22. The design of the protective cap 22 can improve the efficiency of disassembling and replacing the lamp rod 23 and facilitate timely maintenance of the lamp rod 23. The light quality of the lamp rod 23 is blue-green composite light to accurately induce spirulina, improve photosynthetic efficiency, and thus increase the content of phycocyanin. In addition, red light can be added to assist the light quality to adapt to different strains of spirulina. In summary, for the pool body 1 with a water depth of 2 meters, four sets of supplementary lighting modules 2 are respectively set at underwater depths of 0.5 meters, 1.0 meters, 1.5 meters, and 2.0 meters to achieve uniform supplementary lighting at different water depths, solve the problem of light attenuation and dark areas in deep water, and meet the high-efficiency photosynthetic needs of spirulina.

[0024] like Figure 4 , Figures 6-8 Two centrally symmetrical movable modules 6 form a set, and a set of movable modules 6 is externally and movably connected to the supplementary lighting module 2. The movable modules 6 rotate clockwise. By utilizing the self-rotation of a set of movable modules 6 around the center of the supplementary lighting module 2, the outer wall of the supplementary lighting module 2 can be cleaned in a timely and effective manner, thereby enhancing the supplementary lighting effect and improving the cultivation effect. The movable module 6 includes a movable arc plate 61 and a movable inclined plate 62, such as... Figures 9-14There are two movable arc plates 61, each in a semi-circular shape. The inner wall of each movable arc plate 61 is movably engaged with the outer wall of the supplementary lighting module 2. The outer wall of each movable arc plate 61 has a meshing groove and a limiting groove. A movable inclined plate 62 is fixedly connected between the two movable arc plates 61. The inclined plate 62 is tilted, and its centerline is tangential to the radial line of the supplementary lighting module 2. This results in different angles formed between the two sides of the inclined plate 62 and the wall of the protective shell 21. Based on the rotation direction of the inclined plate 62, its two sides are divided into a incoming side and a outgoing side. The surface of the inclined plate 62 is provided with a thin... The film coating enables the movable inclined plate 62 to accurately reflect and transmit blue-green light, thereby improving the light energy utilization efficiency. In addition, taking the clockwise rotation direction of the movable inclined plate 62 when viewed from the end of the supplementary lighting module 2 as a reference, the side of the movable inclined plate 62 that first contacts the outer wall of the protective shell 21 during the rotation is defined as the incoming side, and the side that subsequently passes through the outer wall of the protective shell 21 along the rotation direction is defined as the outgoing side. In summary, the incoming side of the movable inclined plate 62 can easily clean the algae biofilm and enhance the cleaning effect on the protective shell 21, while the outgoing side of the movable inclined plate 62 can refract and reflect the light emitted by the protective shell 21, enhance the supplementary lighting effect, and improve the growth efficiency of spirulina.

[0025] like Figure 4 , Figure 6 Each set of supplementary lighting modules 2 is surrounded by a set of rotating modules 3, and the set of rotating modules 3 is movably connected to multiple sets of movable modules 6. The rotating modules 3 can provide power for the self-rotation of the movable modules 6, and one set of rotating modules 3 can serve multiple sets of movable modules 6 on the same layer, effectively reducing energy consumption. The rotating module 3 includes a rotating shaft 31, a rotating belt 32, and a rotating motor 33, such as Figures 7-8 Each set of supplementary lighting modules 2 is equipped with four rotating shafts 31, and each rotating shaft 31 is movably sleeved on the wall of the pool body 1. A rotating belt 32 is movably sleeved on two rotating shafts 31 located on the same side of the pool body 1. The inner wall of the rotating belt 32 is fixedly connected with toothed blocks, and the rotating belt 32 engages simultaneously with the outer wall of the rotating shaft 31 and the meshing groove of the movable arc plate 61 through the toothed blocks. The rotating belt 32 can jointly drive multiple rotating shafts 31 and multiple movable arc plates 61 located at the same height to rotate together. The rotating motor 33 is fixedly installed outside the pool body 1, and the rotating motor 33 is movably connected to one of the rotating shafts 31. The rotating motor 33 drives the rotating shaft 31 to rotate clockwise, and under the action of the rotating belt 32, drives the movable arc plate 61 and the movable inclined plate 62 to rotate clockwise around the center of the supplementary lighting module 2 to clean the algae biofilm attached to the supplementary lighting module 2.

[0026] like Figure 3The pool 1 contains two sets of aeration modules 4, located at opposite ends of the lighting module 2. The aeration modules 4 supply carbon dioxide gas to the movable module 6, ensuring sufficient carbon dioxide for the spirulina within the pool 1 and improving cultivation efficiency. Each aeration module 4 includes a support frame 41 and several fixing components 5. Each movable module 6 has two corresponding fixing components 5. The upper half of each fixing component 5 is fixedly connected to the outside of the support frame 41, while the lower half is movably engaged with the end of each movable module 6. These two fixing components 5 secure each movable module 6, enhancing its stability. Specifically: like Figure 5 The support frame 41 is fixedly attached to the pool body 1. The support frame 41 consists of a horizontal frame and a vertical frame, and one horizontal frame is set above a group of supplementary lighting modules 2, so that each group of movable modules 6 on the same group of supplementary lighting modules 2 is connected by the same horizontal frame, ensuring that the height of each group of movable modules 6 is uniform.

[0027] like Figures 7-9 The fixing component 5 includes a fixing connecting plate 51, a fixing horizontal plate 52, a fixing arc plate 53, and a fixing tube 54. The fixing connecting plate 51 is U-shaped, and its upper half is movably engaged with the wall of the support frame 41, while its lower half is movably engaged with the limiting groove of the movable arc plate 61. There are two fixing connecting plates 51, and the top of the two symmetrically arranged fixing connecting plates 51 is spliced ​​and fixed by the fixing horizontal plate 52. The fixing horizontal plate 52 connects the two fixing connecting plates 51 to ensure the stability of the splicing of the two fixing connecting plates 51. The internal movable part is equipped with a fixed arc plate 53, and the lower half of the fixed arc plate 53 is movably engaged with the limiting groove of the movable arc plate 61. The upper half of the fixed arc plate 53 is fixedly sleeved with one end of the fixed tube 54, and the other end of the fixed tube 54 is fixedly sleeved with the bottom of the support frame 41. The fixed arc plate 53 is connected by the fixed tube 54 to ensure the stability of the fixed arc plate 53. In summary, the fixed arc plate 53 and the fixed connecting plate 51 are used to effectively limit and fix the two movable arc plates 61 that are spliced ​​together, so as to enhance the connection tightness between the two movable arc plates 61 and ensure their working stability.

[0028] Example 2, based on Example 1, such as Figure 11 The support frame 41 has a main air passage inside, and the main air passage of the support frame 41 is connected to a gas storage box containing carbon dioxide gas.

[0029] like Figure 11 The fixed arc plate 53 has a fixed air passage inside, and the fixed air passage is composed of a fixed arc hole and a fixed straight hole, with one fixed arc hole connected to several fixed straight holes.

[0030] like Figure 11The fixed pipe 54 has a branch gas passage inside, and one end of the branch gas passage is connected to the main gas passage of the support frame 41, and the other end of the branch gas passage is connected to the fixed gas passage of the fixed arc plate 53. Thus, the flow path of carbon dioxide gas in the gas replenishment module 4 is: first enter the main gas passage of the support frame 41, then enter the branch gas passage of the fixed pipe 54, and finally enter the fixed gas passage of the fixed arc plate 53, so as to achieve uniform dispersion of carbon dioxide gas.

[0031] like Figure 11 Both movable arc plates 61 have movable air passages inside, and the movable air passages are composed of movable arc holes and movable straight holes. One movable arc hole is connected to several movable straight holes, and the movable straight holes are intermittently aligned with the fixed straight holes.

[0032] like Figure 12 The movable inclined plate 62 has an output air passage inside, which consists of an output horizontal hole and an output vertical hole. One end of the output horizontal hole is connected to the movable air passage, and the other end of the output horizontal hole is connected to several output vertical holes. Thus, the flow path of carbon dioxide gas in the movable module 6 is as follows: first, it enters the movable air passage of the movable arc plate 61, then enters the output air passage of the movable inclined plate 62, and finally is discharged into the pool body 1, so as to achieve uniform discharge of carbon dioxide gas and supplement raw materials for the growth of spirulina.

[0033] like Figures 12-14 A high-porosity plate 7 is provided on the movable inclined plate 62. The high-porosity plate 7 is fixedly embedded inside the movable inclined plate 62 at the end of the output gas path, and is located on the outgoing side of the movable inclined plate 62. Due to the material characteristics of the high-porosity plate 7, it effectively refines the carbon dioxide gas, improves the contact between carbon dioxide and spirulina, and enhances the fixation effect of the carbon dioxide gas. Furthermore, because the angle formed between the outgoing side of the movable inclined plate 62 and the wall of the supplementary lighting module 2 is small, and the supplementary lighting module 2 is opposite to the outgoing side of the movable inclined plate 62... The wall of module 2 has just been cleaned by the movable inclined plate 62, so that the area can fully refract and reflect light. Then, the carbon dioxide discharged through the high porosity plate 7 is further enhanced by the light, which enhances the fixation effect of carbon dioxide gas. It should be noted that check valves need to be installed in each air passage of the gas supply module 4 and the movable module 6. The check valves only allow gas to flow into the pool 1. Once the gas supply stops or the pressure in each air passage drops, the check valves will automatically close to prevent the liquid in the pool 1 from flowing back.

[0034] Example 3, based on Example 2, such as Figures 12-13The movable inclined plate 62 is also equipped with auxiliary components 8. Several auxiliary components 8 are arranged on the direction of travel of the movable inclined plate 62, and a high-aperture plate 7 is arranged between two adjacent auxiliary components 8. The auxiliary components 8 are used to enhance the reflection and refraction effect of the movable inclined plate 62 on blue and green light, thereby further improving the light energy utilization efficiency. The auxiliary components 8 include auxiliary rods 81, auxiliary plates 82, and auxiliary caps 83, such as... Figure 14 The movable inclined plate 62 has a long groove on its wall surface, and the auxiliary rod 81 is movably engaged in the long groove of the movable inclined plate 62. The cross-sectional shape of the auxiliary plate 82 is a right-angled isosceles triangle, and the right-angled edge of the auxiliary plate 82 is fixedly connected to the middle wall surface of the auxiliary rod 81. The surface of the auxiliary plate 82 is coated with a thin film. Due to the shape design of the auxiliary plate 82, specular reflection is transformed into diffuse reflection, thereby improving the uniformity of illumination and increasing the effective light area volume. When the side wall of the auxiliary plate 82 is attached to the side wall of the movable inclined plate 62, the auxiliary plate 82 completely blocks the high-porosity plate 7 to protect the high-porosity plate 7 and extend its service life. The movable inclined plate 62 has a short groove on its wall surface, and the external thread of the auxiliary cap 83 is threaded into the short groove of the movable inclined plate 62. Inside, the auxiliary cap 83 is movably connected to the end of the auxiliary rod 81, thus using the auxiliary cap 83 to effectively and stably set the auxiliary rod 81 and the auxiliary plate 82 on the movable inclined plate 62, and also to facilitate the removal of the auxiliary rod 81 and the auxiliary plate 82 from the movable inclined plate 62. In summary, when the supplementary lighting module 2 is cleaning, the two movable arc plates 61 in a set of movable modules 6 will rotate, so that the fixed air passage on the fixed arc plate 53 and the movable air passage on the movable arc plate 61 are intermittently connected. Thus, the impact force of carbon dioxide on the auxiliary component 8 when it is discharged from the movable inclined plate 62 will change continuously. At the same time, in conjunction with the rotational force of the movable inclined plate 62, the auxiliary component 8 will swing continuously, further enhancing the refraction and reflection effect on the direction of the movable inclined plate 62.

[0035] The working principle of this invention is as follows: When pool 1 is in operation, each group of aeration modules has a 4-layer design and emits blue-green light, which can supplement the light at different water depths in pool 1, solve the problem of light attenuation in deep water and dark areas, and meet the high-efficiency photosynthesis needs of spirulina.

[0036] When cleaning the supplemental lighting module 2, the rotating motor 33 is activated to drive the rotating shaft 31 to rotate clockwise and the rotating belt 32 to circulate clockwise, which can drive a set of movable modules 6 to rotate clockwise. During this process, because the two movable inclined plates 62 are designed at an angle, the side of the movable inclined plates 62 that is coming from can rub against the outer wall of the protective shell 21 and remove the algae biofilm attached to the outer wall of the protective shell 21, effectively ensuring the supplemental lighting effect and improving the cultivation effect of spirulina. At the same time, the side of the movable inclined plates 62 that is going to the outside can refract and reflect the light emitted by the newly cleaned protective shell 21, effectively protecting the shell 21 and enhancing the supplemental lighting effect, further improving the cultivation effect of spirulina.

[0037] When spirulina is supplemented with gas, carbon dioxide gas flows sequentially through the main gas path of the support frame 41, the branch gas path of the fixed pipe 54, the fixed gas path of the fixed arc plate 53, the movable gas path of the movable arc plate 61, and the output gas path of the movable inclined plate 62, and is finally evenly discharged into the pool 1. The carbon dioxide gas is discharged towards the destination area of ​​the movable inclined plate 62, so that the carbon dioxide gas is fully fixed in the pool 1 under the influence of light and is utilized by the spirulina in a timely manner. During this process, because the fixed arc plate 53 is fixed and the movable arc plate 61 is rotating, the fixed gas path on the fixed arc plate 53 and the movable gas path on the movable arc plate 61 are intermittently connected. As a result, the impact force of carbon dioxide on the auxiliary component 8 when it is discharged from the movable inclined plate 62 will change continuously, so that the auxiliary component 8 will swing continuously. This not only enhances the refining effect of carbon dioxide gas in conjunction with the high porosity plate 7 and improves the contact between carbon dioxide and spirulina, but also enhances the refraction and reflection effect of the destination side of the movable inclined plate 62, thereby further improving the cultivation effect of spirulina.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
