DETAILED DESCRIPTION

[0041] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0042] Example 1

[0043] A pollution-proof photosynthetic bacteria culture device capable of controlling light intensity, such as Figure 1-5 As shown, it includes a supporting base frame 1, a swinging assembly 2 and a limiting assembly 3. The supporting base frame 1 is provided with the swinging assembly 2, and the swinging assembly 2 is provided with the limiting assembly 3 for limiting the swinging assembly 2.

[0044] The swing assembly 2 includes a swing placement frame 21, a fixed glass frame 22, a culture dish 23, a first support frame 24, an electric push rod 25 and a slotted frame 26. The swing placement frame 21 is rotatably connected to the support base frame 1. A fixed glass frame 22 for easy observation is fixedly installed on the top of the swing placement frame 21. A culture dish 23 for culturing photosynthetic bacteria is placed on the swing placement frame 21. The culture dish 23 fits tightly with the fixed glass frame 22. The first support frame 24 is fixedly installed on the support base frame 1 close to the swing placement frame 21. An electric push rod 25 is fixedly installed on the first support frame 24. A slotted frame 26 is welded to the top of the telescopic shaft of the electric push rod 25. The slotted frame 26 is limitedly matched with the swing placement frame 21, and the slotted frame 26 is used to push the swing placement frame 21 to swing.

[0045] The limiting assembly 3 includes a limiting frame 31 and a first spring 32. The limiting frame 31 is symmetrically and slidingly connected to the swing placement frame 21. The limiting frame 31 and the culture dish 23 are in contact with each other. The limiting frame 31 is used to block the culture dish 23. The first spring 32 is connected between the limiting frame 31 and the swing placement frame 21.

[0046] The staff puts the culture dish 23 containing photosynthetic bacteria and culture solution into the swing placement frame 21. The culture dish 23 will push the limit frame 31 to move relative to each other, and then the limit frame 31 moves toward each other through the reset action of the first spring 32 to block the culture dish 23. The fixed glass frame 22 can facilitate the staff to observe the cultivation of photosynthetic bacteria. The staff manually controls the extension and contraction of the electric push rod 25 every 6 hours. When the electric push rod 25 is extended, the electric push rod 25 extends and drives the slotted frame 26 to move upward. When the electric push rod 25 is retracted, the electric push rod 25 retracts and drives the slotted frame 26 to move downward. The reciprocating movement of the slotted frame 26 drives the swing placement frame 21 and the device thereon to swing back and forth, replacing the manual shaking of the culture dish 23, so that the precipitated photosynthetic bacteria in the culture dish 23 float up, which is convenient for the photosynthetic bacteria to obtain sunlight, thereby enabling the good growth of bacterial cells.

[0047] Example 2

[0048] On the basis of Example 1, Figure 3 , 6 -9, also includes an exhaust component 4, the exhaust component 4 is arranged on the swing placement frame 21, the exhaust component 4 is used to discharge hydrogen, the exhaust component 4 includes a first exhaust pipe 41, a support frame 42, a first sliding support frame 43, a second spring 44, a second exhaust pipe 45, a second sliding support frame 46, a blocking frame 47, a second support frame 48, a first rotating block 49, a second rotating block 410 and a third spring 411, the first exhaust pipe 41 is arranged on the swing placement frame 21, the first exhaust pipe 41 is communicated with the culture dish 23, one end of the first exhaust pipe 41 is connected to the support frame 42, the support frame 42 is slidably connected with the first sliding support frame 43, the first sliding support frame 43 is provided with a plurality of air outlets, the first sliding support frame 43 is connected to the support frame 4 2, a second spring 44 is connected between the support frame 42, a second exhaust pipe 45 is connected to the support frame 42, a second sliding support frame 46 is slidably connected to the support frame 42 close to the first sliding support frame 43, a blocking frame 47 is welded to one end of the second sliding support frame 46, the blocking frame 47 is slidably connected to the first sliding support frame 43, the blocking frame 47 is used to block the air outlet on the first sliding support frame 43, a second support frame 48 is welded to the first sliding support frame 43, the second support frame 48 and the second sliding support frame 46 are in contact with each other, a first rotating block 49 is rotatably connected to the second support frame 48, a second rotating block 410 is rotatably connected to the second sliding support frame 46, and a third spring 411 is connected between the second rotating block 410 and the first rotating block 49.

[0049] When photosynthetic bacteria perform photosynthesis, they will produce hydrogen. When the bacterial cells inside the culture dish 23 produce a large amount of hydrogen, the pressure in the enclosed space formed by the culture dish 23 and the fixed glass frame 22 increases, and the hydrogen enters the support frame 42 through the first exhaust pipe 41. The hydrogen will push the first sliding support frame 43 and the blocking frame 47 to move away from the first exhaust pipe 41. Then the support frame 42 blocks the second sliding support frame 46, and the blocking frame 47 no longer blocks the air outlet on the first sliding support frame 43. The hydrogen in the support frame 42 can be discharged from the second exhaust pipe 45 through the air outlet, which is beneficial to the reproduction of photosynthetic bacteria. After the hydrogen is discharged, the pressure in the enclosed space formed by the culture dish 23 and the fixed glass frame 22 decreases, and the stretched second spring 44 is reset, driving the first sliding support frame 43 and the device thereon to move toward the direction close to the first exhaust pipe 41 and reset. The blocking frame 47 blocks the air outlet on the first sliding support frame 43, and then the first sliding support frame 43 pushes the blocking frame 47 and the second sliding support frame 46 to move toward the direction close to the first exhaust pipe 41 and reset.

The top of the liquid guide tube 51 is connected to the first liquid storage frame 52. The top of the first liquid storage frame 52 is jointly fixed with the second liquid storage frame 53 for storing nutrient solution. The second liquid storage frame 53 is fixed to the swing placement frame 21. The perforated plate 54 is welded inside the first liquid storage frame 52. 4.

[0057] It also includes a second toggle assembly 9, which is arranged on the top of the second liquid storage frame 53. The second toggle assembly 9 includes a slotted guide plate 91, a toggle bar 92 and a seventh spring 93. A slotted guide plate 91 is welded on the top of the second liquid storage frame 53, and a toggle bar 92 is slidably connected to the extrusion frame 58.

[0059] When the extrusion frame 58 moves upward to reset, the extrusion frame 58 will drive the toggle bar 92 to move upward, and through the action of the slotted guide plate 91, the toggle bar 92 moves away from the third support frame 71 to reset. Since the pawl 89 clamps the ratchet frame 84, the compressed sixth spring 82 will not reset. The more hydrogen the bacterial cells produce, the greater the pressure in the closed space formed by the culture dish 23 and the fixed glass frame 22. Repeating the above operation, the third sliding support frame 81 and the device thereon will intermittently move downward, and the illumination range will gradually expand, achieving the purpose of controlling the illumination intensity as needed. When the second guide frame 86 and the support plate 88 are in contact with each other, the second guide frame 86 will push the support plate 88 and the device thereon to move away from the third support frame 71, and the pawl 89 will no longer clamp the ratchet frame 84. The compressed sixth spring 82 is reset to drive the third sliding support frame 81 and the device thereon to move upward, so that the concave lens frame 811 reduces the illumination range of the light. After that, the first guide frame 85 and the support plate 88 are in contact with each other, and the first guide frame 85 pushes the support plate 88 and the device thereon to move toward the third support frame 71, and the pawl 89 clamps the ratchet frame 84 again. After the photosynthetic bacteria are cultured, the staff removes the culture dish 23 from the swing placement frame 21.
