Description

Technical Field

[0001] The utility model relates to an illumination adjusting device for algae cultivation. Background Art

[0002] Algae are a type of eukaryote in the kingdom Protista (some are also prokaryotes, such as algae in the Cyanophyta phylum). They are mainly aquatic, without vascular bundles, can perform photosynthesis, and vary in size, from single-celled flagellates as small as 1 micrometer in length to large brown algae as long as 60 meters. The cultivation sites and scenarios for cultivating algae plants are diverse, such as outdoor field cultivation or indoor box cultivation, etc. For outdoor field cultivation, the inventor found that the ceiling of the outdoor seedling house is only covered with a woven straw mat on the glass. When the light intensity needs to be adjusted, the straw mat is rolled up manually by climbing a ladder, so that natural light can shine into the seedling house. Although this method can achieve the effect, it is particularly inconvenient in actual use. At the same time, it is also impossible to effectively adjust according to the growth cycle of the algae plants, which may cause the algae plants to not receive the optimal light, resulting in slow growth of the algae plants and poor cultivation effects.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0025] Referring to Figure 1-2 As shown, an algae cultivation light regulation device includes a seedling raising house 1, a seedling raising pond 2, and a ceiling 4. The ceiling 4 is provided at the top of the seedling raising house 1, and the seedling raising pond 2 is provided inside the seedling raising house 1;

[0026] It further includes a light transmissive member 7. The light transmissive member 7 includes a first grid curtain 70, a second grid curtain 71, a third grid curtain 72, and a fourth grid curtain 73 connected in sequence;

[0027] Among them, a number of first holes 700, second holes 710, third holes 720, and fourth holes 730 are respectively formed on the first grid curtain 70, the second grid curtain 71, the third grid curtain 72, and the fourth grid curtain 73 at equal intervals. Further, the first holes 700, second holes 710, third holes 720, and fourth holes 730 are circular, triangular, square, rectangular, hexagonal, or oval, etc. In one embodiment, to ensure the light transmittance of natural light. Preferably, the first holes 700, second holes 710, third holes 720, and fourth holes 730 are all circular.

[0028] The first hole 700, the second hole 710, the third hole 720, and the fourth hole 730 have light transmittances Q, W, E, and R respectively. Among them, the light transmittance Q is 85%-90%, the light transmittance W is 50%-80%, the light transmittance E is 10%-20%, and the light transmittance R is 8%-5%.

[0029] A hollow groove 5 is provided on the ceiling 4, and glass is provided in the hollow groove 5. The glass is composed of a first glass, a second glass, and a third glass. To ensure the more effective growth of algae, the first glass, the second glass, and the third glass are low-iron glass, anti-ultraviolet glass, and transparent glass respectively. The three groups of glass are combined in sequence. The low-iron glass as the outer layer can improve the overall light transmittance. The anti-ultraviolet glass as the middle layer can filter out the ultraviolet rays harmful to algae. The transparent glass as the inner layer can maintain the internal lighting environment, so as to provide the required lighting environment for cultivating algae and optimize the lighting environment. Further, as an embodiment of this case, the first glass, the second glass, and the third glass can also be colored glass, insulating glass, and low-iron glass. The colored glass is used to adjust the quality and quantity of the incoming light. The insulating glass provides heat insulation effect. The low-iron glass is used as the inner layer to ensure high light transmittance. The above glass combination methods include but are not limited to two, and suitable glass can be selected for combination according to actual needs. Moreover, the combination of the three glasses can provide diverse lighting and environmental control options, but careful evaluation and design are required according to the specific cultivation requirements and environmental conditions of the algae.

[0030] The first grid curtain 70, the second grid curtain 71, the third grid curtain 72, and the fourth grid curtain 73 are all made of special coated fabric. Specifically, the special coated fabric is made by coating one or more layers of polymer materials with special functions on the base fabric, such as anti-ultraviolet coating, waterproof coating, or anti-fouling coating. Thereby, the applicability and durability of the first grid curtain 70, the second grid curtain 71, the third grid curtain 72, and the fourth grid curtain 73 outdoors can be improved.

[0031] The first light control grid curtain 70, the second light control grid curtain 71, the third light control grid curtain 72 and the fourth light control grid curtain 73 form a light control grid curtain; there is a spacing A between the light control grid curtain and the glass, where 0.5 cm ≤ A ≤ 4 cm. To avoid excessive temperature of natural light illumination. Preferably, 2 cm ≤ A ≤ 4 cm. More preferably, 3 cm ≤ A ≤ 4 cm. In multiple embodiments thereof, A is approximately 3.2 cm, 3.5 cm and 3.8 cm respectively. Among them, Embodiment 1 (A = 3.2 cm): At this spacing, the intensity of natural light illumination is effectively regulated, which not only ensures sufficient illumination but also avoids thermal damage to algae plants caused by excessive illumination. In practical applications, the algae plants show a good growth trend and the photosynthesis efficiency is improved. If the spacing is too large, the light control grid curtain will block the irradiation of natural light and reduce the illumination intensity. Embodiment 2 (A = 3.5 cm): The spacing A of 3.5 cm provides a mild illumination environment for the algae plants and at the same time maintains a suitable temperature range. At this spacing, the growth rate and biomass of the algae plants both reach the expected goals. Embodiment 3 (A = 3.8 cm): Selecting 3.8 cm as the spacing A aims to explore the heat insulation and light control effects of the light control grid curtain at a larger spacing. The experimental results show that even under the condition of a larger spacing, through precise light control management, the healthy growth of the algae plants can still be maintained. More preferably, A is approximately 3.5 cm, because among the growth data of the algae plants in the three embodiments, the spacings A of 3.2 cm, 3.5 cm and 3.8 cm can all provide a suitable growth environment. However, the spacing of 3.5 cm shows the best balance point after comprehensively considering the illumination intensity, temperature control and maintenance convenience. Further, if the spacing is too small, there will be no air layer between the light control grid curtain and the glass, and thus the heat insulation effect cannot be achieved, which may increase the irradiation intensity of natural light and thus affect the growth of the algae plants. Further, reserving the spacing A can also ensure that the light control grid curtain and the glass are convenient for cleaning and maintenance work.

[0032] The present utility model further includes a light detection module 3, which is used to detect and adjust the artificial light source in the seedling cultivation room 1, so as to facilitate the cultivation of algae plants.

[0033] An adjusting mechanism 6 is further provided. The adjusting mechanism 6 includes a first motor 60 and a second motor 63 fixedly arranged on the ceiling 4 and at the opening edge of the hollow groove 5, and a limiting bracket 63 for limiting the rotating shaft 62 is symmetrically arranged on one side of each of the first motor 60 and the second motor 63.

[0034] Further, the light control grille curtain is wound around the rotating shaft 62 of the first motor 60 and the second motor 63. When the first motor 60 and the second motor 63 are turned on, the light control grille curtain will rotate with the rotating shaft 62 to adjust different first holes 700, second holes 710, third holes 720, and fourth holes 730, so as to correspond to the natural light illumination intensity required by the algae plants.

[0035] Further, the control unit is respectively connected to the light detection module 3, the adjustment mechanism 6, and the light transmissive member 7, and is used to control the adjustment mechanism 6 to adjust the light transmissive member 7 according to the light intensity detected by the light detection module 3.

[0036] The embodiment of the present utility model further provides an automatic control method for an algae cultivation light adjustment device to cultivate kelp, including the following steps:

[0037] Obtain the growth stage of the kelp and the corresponding light intensity. Among them, the growth stage includes the bud pregnancy stage, the seedling stage, and the growth stage. Among them, the light intensity corresponding to the bud pregnancy stage is 500 lm to 800 lm; the light intensity corresponding to the seedling stage is 1000 lm to 2000 lm; the light intensity corresponding to the growth stage is 5000 lm to 8000 lm;

[0038] Obtain the real-time light intensity through the light detection module 3, and wind up the light transmissive member 7 through the adjustment mechanism 6 to make it meet the light intensity corresponding to the kelp production stage.

[0039] It should be noted that in the present invention, the setting of the light transmittance is based on the research on the light requirements of kelp under normal growth conditions. As a photosynthetic organism, kelp has specific requirements for light intensity. Under normal weather conditions, the growth environment of kelp requires a specific light intensity to ensure the effective progress of its photosynthesis.

[0040] Regarding the growth of kelp, the following explanations are made in this case:

[0041] Bud pregnancy stage: The kelp has relatively low light requirements during the bud pregnancy stage. In the present invention, the light transmittance of the fourth grille curtain 73 is set to 8% - 5%, and the light intensity needs to be maintained at 500 lm to 800 lm to promote the balanced development of the young buds and ensure that the kelp can still obtain appropriate light during weak light periods such as morning or evening.

[0042] Seedling stage: As the kelp enters the seedling stage, the light requirements increase. The light transmittance of the third grille curtain 72 is set to 10% - 20%, and the light intensity needs to be increased to 1000 lm to 2000 lm to support the rapid growth of the seedlings. At the same time, it can also adapt to the light changes in different time periods of the whole day.

[0043] Growth period: During the growth period, kelp requires strong light to support rapid growth. The light transmittance of the second grid curtain 71 is set at 50%-80% to adjust the light intensity during the noon period with strong sunlight. Among them, during the growth period, if the light transmittance of the second grid curtain 71 cannot meet the growth intensity of kelp, the control unit can control the adjustment mechanism 6 to adjust the light-transmitting member 7 and rotate it to the first grid curtain 70 to increase the light transmittance to 85%-90%. The light intensity needs to reach 5000 lm to 8000 lm to maintain the healthy growth of kelp and thus meet the growth requirements of kelp.

[0044] This device ensures that kelp can obtain appropriate light conditions at each growth stage by automatically adjusting the light intensity, thereby improving the breeding efficiency and the quality of kelp.

[0045] Furthermore, in case of special weather conditions, such as continuous cloudy days, heavy rain or high ultraviolet radiation conditions, the light requirements of kelp may be different from those in normal weather, as follows:

[0046] Example 1: Continuous cloudy days

[0047] S1: The light detection module 3 detects that the natural light intensity continuously drops below the minimum light intensity required for the budding period of kelp.

[0048] S2: The control unit controls the adjustment mechanism to adjust the grid curtain to the first grid curtain 70 to meet the light requirements of kelp.

[0049] S3: When the light intensity transmitted by the first grid curtain 70 cannot meet the light requirements of kelp, the control unit activates the artificial light source to supplement the insufficient light.

[0050] S4: According to the feedback of the light detection module 3, the control unit adjusts the brightness of the artificial light source to ensure that the total light intensity reaches the target value for the budding period.

[0051] S5: Under continuous cloudy conditions, the control unit adjusts the opening and closing degree of the light control grid curtain to balance the total light intensity of natural light and the artificial light source.

[0052] S6: If the actual light intensity is higher than the target value, the control unit will adjust the third grid curtain 73 and the fourth grid curtain 74 to reduce the light transmittance and turn off the artificial light source at the same time.

[0053] Example 2: Heavy rain weather

[0054] S1: During heavy rain, the light detection module 3 detects a sharp change in light intensity.

[0055] S2: The control unit responds quickly and adjusts the opening and closing degree of the light control grid curtain to adapt to the rapidly changing light conditions.

[0056] S3: If heavy rain causes a sharp drop in natural light intensity, the control unit can increase the brightness of artificial light sources to maintain the stability of the total light intensity;

[0057] S4: After the heavy rain, the control unit gradually adjusts the light control grille curtain to restore to the normal light control mode.

[0058] Embodiment 3: High ultraviolet radiation

[0059] S1: The light detection module 3 detects that the ultraviolet radiation intensity exceeds the preset safety threshold;

[0060] S2: After receiving the signal, the control unit immediately adjusts the fourth grille curtain 74 to the lowest light transmittance to reduce the damage of ultraviolet rays to kelp;

[0061] S3: At the same time, the control unit activates the sunshade system (not shown in the figure) or uses a grille curtain with an ultraviolet-resistant coating to provide additional protection;

[0062] S4: The control unit continuously monitors the ultraviolet intensity and adjusts other grille curtains according to the situation to ensure the growth of kelp under safe light conditions.

[0063] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
