[0001] The invention relates to the technical field of algae cultivation, in particular to a cultivation device for rapid algae propagation. Background Art

[0002] Algae cultivation refers to the process of promoting the growth and reproduction of algae in an artificial environment by providing appropriate conditions such as light, temperature, nutrients, and gases. Algae are a type of single-celled or multi-cellular plant, including phytoplankton and attached algae, and are widely found in water bodies such as oceans, freshwater, and soil. The purpose of algae cultivation can be scientific research, industrial application, or environmental remediation. Chinese Patent No. CN106010939A discloses an algae cultivation device, including an incubator, which includes an outer box body, an inner box body, and a box cover. The box cover can cover the outer box body and the inner box body. A sealing structure is provided between the box cover and the inner box body to seal the inner box body.

A plurality of fixing rods of different lengths are vertically fixed to the bottom surface of the inner box body. The upper ends of the fixing rods are fixed to a transparent glass cover, and the transparent glass cover is provided with a cool white fluorescent lamp. Although this device has the advantage of being able to accurately control the growth of algae and increase the yield of algae, as the algae are cultivated for a long time, the algae cells in the device excessively aggregate to form a light-shielding layer, which reduces the efficiency of photosynthesis. In view of this, the present invention proposes a culture device for rapid algae propagation to remedy and improve the shortcomings of the prior art. Summary of the Invention

The output end of the servo motor 31 is fixedly connected to a rotating shaft 32. The outer surface of the rotating shaft 32 is fixedly connected to a stirring blade 33. The outer surface of the rotating shaft 32 is fixedly connected to a main turntable 34.

The end of the reciprocating screw 37 close to the servo motor 31 is fixedly connected to a secondary turntable 36. A belt 35 is connected between the secondary turntable 36 and the main turntable 34. The outer surface of the reciprocating screw 37 is threadedly connected to a moving block 38, and the moving block 38 is slidably connected to the incubator 1.

[0017] Please refer to Figures 2 to 6 As shown, the sampling mechanism 4 includes a rotating frame 41 fixedly mounted on the top of the incubator 1, a rotating column 42 is rotatably connected to the rotating frame 41, a knob 43 is fixedly connected to the driving end of the rotating column 42, and an insertion rod 44 is inserted into the rotating frame 41; A pulling rope 45 is wound and fixed on the outer surface of the rotating column 42, and one end of the pulling rope 45 away from the rotating column 42 is fixedly connected to a pressure plate 46; A top post 47 is slidably connected to the pressure plate 46. The top end of the top post 47 is fixedly connected to a limiting disc 48. The bottom end of the limiting disc 48 is fixedly connected to a spring 49. The bottom end of the top post 47 is fixedly connected to a blocking block 410. A ventilation hole 411 is provided on the pressure plate 46, and a magnetic block 412 is hinged on the support base 5; Supplementary explanation: A avoidance hole is provided at the top of the incubator 1, and the diameter of the avoidance hole is larger than the diameter of the pulling rope 45; The knob plate 43 is provided with blocking holes at equal intervals, and the insertion rod 44 passes through the blocking holes and is inserted into the rotation rack 41; A cross slot is provided on the inner wall of the incubator 1, and a sliding block is fixed on the outer surface of the pressing plate 46, and the sliding block slides on the cross slot; A counterweight is fixed at the center of the pressure plate 46, and one end of the spring 49 away from the limiting disc 48 abuts against the pressure plate 46; The blocking block 410 is located directly below the vent hole 411, and the width of the blocking block 410 is greater than the diameter of the vent hole 411; The above solution adopts the sampling mechanism 4, which can loosen the winding position of the pulling rope 45, so that the pressure plate 46 is affected by gravity and moves vertically downward along the incubator 1. The spring 49 supports the sealing block 410 to block the ventilation hole 411. In this way, the movement of the pressure plate 46 evenly discharges the algae in the incubator 1 through the discharge pipe 6, preventing the algae mud from clogging the discharge pipe, so that the device can smoothly sample and discharge the cultured algae. Through the provided sampling mechanism 4, the rotation of the knob disk 43 can also be utilized to make the pulling rope 45 continuously wrapped around the rotating column 42, thereby carrying the pressure plate 46 to move vertically upward along the incubator 1, and the incubator 1 blocks the limiting disc 48, squeezing and contracting the spring 49, so that the blocking block 410 is separated from the blockage of the ventilation hole 411, thereby making it convenient for personnel to pass the algae through the injection tube 7 and the ventilation hole 411 and pour into the inner cavity of the incubator 1.

[0018] The working principle and use process of the present invention: The staff first rotates the knob 43 clockwise to continuously wrap the pulling rope 45 around the rotating column 42, and pulls the pressure plate 46 vertically upward until the incubator 1 blocks the limiting disc 48. The spring 49 is squeezed and contracted to release the blocking block 410 from blocking the vent hole 411. At this time, the insertion rod 44 is inserted through the blocking hole and connected to the rotation rack 41. Then, the algae are poured into the inner cavity of the incubator 1 through the injection tube 7 and the vent hole 411 for reproduction and cultivation; Then the servo motor 31 is controlled to start. Since the output end of the servo motor 31 is fixedly connected to the rotating shaft 32, the outer surface of the rotating shaft 32 is fixedly connected to the stirring blade 33, the outer surface of the rotating shaft 32 is fixedly connected to the main turntable 34, and one end of the reciprocating screw 37 is fixedly connected to the auxiliary turntable 36. The transmission belt 35 is connected between the auxiliary turntable 36 and the main turntable 34, so that the stirring blade 33 and the reciprocating screw 37 rotate along with the rotation of the rotating shaft 32. The stirring blade 33 rotates, which will cause the incubator 1 to rotate. The algae in the inner cavity are stirred, and the rotation of the reciprocating screw 37 causes the outer surface of the reciprocating screw 37 to be threadedly connected to the moving block 38, and the moving block 38 is slidably connected to the incubator 1. The outer surface of the moving block 38 is fixedly connected to the push rod 39, which causes the moving block 38 to carry the push rod 39 and the piston block 310 to reciprocate horizontally along the reciprocating screw 37. Therefore, the piston block 310 continuously sends external air into the incubator 1 through the air inlet 312, the air supply pipe 311 and the vent pipe 313; Then, when it is necessary to sample the algae in the inner cavity of the incubator 1, the servo motor 31 is controlled to be closed, so that the piston block 310 stops at the position where the air inlet 312 is blocked, and then the magnetic block 412 is moved to disengage the magnetic block 412 from the blockage of the discharge pipe 6. Then, the carrier dish is placed under the open end of the discharge pipe 6, and then the insertion rod 44 is dragged to disengage it from the obstruction of the knob disk 43. At this time, the pressure plate 46 is affected by gravity and moves vertically downward along the incubator 1. It is supported by the rebound of the spring 49, so that the blocking block 410 blocks the ventilation hole 411. In this way, the movement of the pressure plate 46 evenly discharges the algae in the incubator 1 through the discharge pipe 6 to the carrier dish to complete the sampling.
