By rotating the shading plate 1 51, the shading plate 2 52 and the shading plate 3 53, the light holes 56 opened on them are blocked, so as to adjust the intensity of light and realize flexible control of lighting conditions to meet the light requirements of microalgae at different growth stages. The top of the shading plate 1 51 is provided with light holes 56, and a plurality of light holes 56 are arranged, which are respectively opened at the top of the shading plate 2 52 and the shading plate 3 53.

[0033] Reference Figure 2 and Figure 3 A guide groove 55 is provided at the top of the sunshade plate 1 51, and there are multiple groups of guide grooves 55, which are respectively arranged at the tops of the sunshade plate 2 52 and the sunshade plate 3 53. A pull rod 54 is fixedly connected to the left side of the sunshade plate 2 52, and there are multiple groups of pull rods 54, which are respectively arranged at the tops of the sunshade plate 1 51 and the sunshade plate 3 53. Through the coordinated use of the multiple groups of guide grooves 55 and the pull rods 54, the user can easily rotate the sunshade plate 1 51, the sunshade plate 2 52 and the sunshade plate 3 53 by operating the pull rods 54, which simplifies the operation process and improves the accuracy of the operation. At the same time, by adjusting the position of the pull rod 54 in the guide groove 55, the rotation angle and position of the sunshade can be accurately controlled.

[0034] Reference Figure 2 and Figure 4The inner wall of the fixed rod 4 is provided with a stirring assembly, which includes a stirring rod 61. The stirring rod 61 rotates to help evenly distribute nutrients, reduce the risk of local overnutrition, and thus reduce the possibility of water bloom. The outer wall of the stirring rod 61 is rotatably connected to the inner wall of the fixed rod 4. The bottom end of the stirring rod 61 is set in a fork shape. The fork-shaped design can increase the contact area between the stirring rod 61 and the liquid, thereby improving the stirring efficiency and mixing uniformity. A limiting groove 62 is provided on the right side of the support rod 3. The limiting groove 62 It is used to provide support and adjustment for the two groups of limit plates 63. The inner wall of the limit groove 62 is slidably connected to the limit plate 63. A protrusion is provided on the upper side of the limit plate 63, which can limit the stirring rod 61 and increase the stability of the stirring rod 61 when placed. There are two groups of limit plates 63, and the two groups of limit plates 63 are elastically connected by a reset spring 64. The right outer wall of the top end of the stirring rod 61 slides on the inner wall of the limit plate 63, and the two groups of limit plates 63 are tightly attached to the outer wall of the stirring rod 61 by the elastic force of the reset spring 64, thereby fixing the stirring rod 61.

[0035] Reference Figure 3 and Figure 5 The inner wall of the second shading plate 52 is provided with a limiting component, which includes a ball bearing 71. The ball bearing 71 slides on the bottom end of the shading plate 1 51 and the top end of the shading plate 3 53 to reduce friction. The outer wall of the ball bearing 71 is slidably connected to the inner wall of the second shading plate 52. Two groups of ball bearings 71 are provided. The two groups of ball bearings 71 are respectively arranged at the upper and lower ends of the second shading plate 52 to ensure that the upper and lower ends of the second shading plate 52 can obtain uniform support and sliding effects when the second shading plate 52 moves or rotates. The two groups of ball bearings 71 are elastically connected by compression springs 72. The elastic force of the compression springs 72 can squeeze the two groups of ball bearings 71 to both sides so that the ball bearings 71 can slide into the inner wall of the limiting groove 73, thereby limiting the first shading plate 51 and the third shading plate 53. The bottom end of the first shading plate 51 and the top end of the third shading plate 53 are respectively provided with limiting grooves 73, and the outer wall of the ball bearing 71 slides on the inner wall of the limiting groove 73.

[0036] Working principle: When it is necessary to adjust the illumination of Spirulina during use, the guide groove 55 drives the shading plate 1 51 to rotate around the fixed rod 4, so that the light-transmitting hole 56 on the shading plate 1 51 overlaps or blocks the light-transmitting holes 56 on the shading plate 2 52 and the shading plate 3 53, thereby changing the light transmission rate and adjusting the illumination conditions required by Spirulina.

[0037] At the same time, the ball 71 on the inner wall of the shading plate 2 52 slides on its surface when the shading plate 1 51 and the shading plate 3 53 rotate, squeezing the ball 71 into the inner wall of the shading plate 2 52, squeezing the compression spring 72, and pushing the ball 71 into the inner wall of the limiting groove 73 through the elastic force of the compression spring 72, thereby limiting the shading plate 1 51 and the shading plate 3 53, so that the shading component can be accurately adjusted according to the specific lighting requirements of Spirulina, and can achieve flexible control of the lighting conditions to meet the lighting requirements of Spirulina at different growth stages.

[0038] When it is necessary to stir the liquid inside the breeding barrel 1, the stirring rod 61 is pulled upward to make it slide out from the inner walls of the two sets of limit plates 63, driving the limit plates 63 to slide to both sides on the inner walls of the limit grooves 62, and at the same time stretching the return spring 64 to release the restriction on the stirring rod 61. At this time, the stirring rod 61 can be rotated to stir the liquid inside the breeding barrel 1, preventing excessive accumulation of nutrients in a certain area, helping to evenly distribute nutrients, and reducing the risk of local overnutrition, thereby reducing the possibility of algal bloom.
