[0041] When the above structure is in use, microalgae and nutrient solution are first added into the microalgae bioreactor 1, and then the driving motor 411 drives the driving shaft 401 to rotate, so that the driving shaft 401 drives the heat exchange tube 405 to rotate through the first connecting frame 402 and the annular frame 403, and the condensed water with waste heat passes through the liquid inlet pipe 408, the water inlet cavity of the annular frame 403, the heat exchange tube 405, the water outlet cavity of the annular frame 403 and is finally discharged outward through the liquid outlet pipe 409. Since the middle part of the heat exchange tube 405 is flat, the heat exchange time of the condensed water can be extended and the heat exchange efficiency can be improved.

[0043] The third connecting frame 701 moves back and forth up and down along the fixed column 407, so that the third connecting frame 701 drives the cleaning ring 703, the articulated arm 704 and the cleaning rubber sleeve 705 to move up and down, and the brushes on the inner walls of the cleaning ring 703 and the cleaning rubber sleeve 705 respectively clean the dirt generated by the growth of microalgae on the surfaces of the heat exchange tube 405 and the lamp tube 412, thereby improving the heat exchange efficiency of the heat exchange tube 405.

In the middle of the fixed column 407, the two ends of the inner wall of the transmission belt 505 are respectively fixedly installed with a first movable block 509 and a second movable block 510, and the first movable block 509 and the second movable block 510 are staggered up and down, a connecting pipe 511 is fixedly installed on the surface of the first movable block 509, and the connecting pipe 511 is fixedly installed at one end of the third connecting frame 701, a first movable groove 508 is opened in the middle of the fixed column 407 corresponding to the position of the driving roller 504 and the driven roller 506, and the driving roller 504 and the first movable groove 508 are respectively rotatably connected to the inner wall of the first movable groove 508, and the two ends of the inner wall of the first movable block 509 and the second movable block 510 are respectively fixedly installed with a guide block 512, and one end of the fixed column 407 corresponding to the position of the guide block 512 is opened with a first guide groove 513, and the guide block 512 is movably connected to the inner wall of the first guide groove 513;

[0045] When the above structure is in use, the driving shaft 401 will rotate relative to the fixed column 407, and the driving shaft 401 will drive the face gear 501 to engage with the driven gear 502, and the driven gear 502 will drive the transmission belt 505 through the connecting shaft 503 and the driving roller 504, and then the transmission belt 505 will drive the first movable block 509 and the second movable block 510 to move alternately with each other, so that the first movable block 509 drives the connecting tube 511 to move up and down along the direction of the fixed column 407.

[0046] The present invention also includes a reversing component for changing the rotation direction of the driving roller 504, and the reversing component includes two support frames 601 rotatably connected to the two ends of the connecting shaft 503 through bearings, and a connecting arm 602 is fixedly installed at one end of the opposite surface of the two support frames 601, and the connecting arm 602 movably passes through and extends to the two ends of the fixed column 407, and a second movable groove 603 is opened in the middle of the fixed column 407 corresponding to the position of the connecting arm 602, and a driving block 604 is fixedly installed at the bottom of the connecting arm 602 corresponding to the position of the second movable groove 603, and a third movable groove 605 is respectively opened at both ends of the fixed column 407 corresponding to the position of the first movable block 509 and the second movable block 510, and the interior of the third movable groove 605 is connected to the interior of the driving block 604, and the two third movable grooves 605 are staggered.

After the connecting arm 602 continues to move, the return spring in the power-assisting component 608 will quickly assist the connecting arm 602 to move, so that the two driven gears 502 can quickly switch to a state of meshing with the face gear 501, thereby avoiding the situation where the meshing state of the two driven gears 502 and the face gear 501 is not switched smoothly;

[0047] When the above structure is in use, the first movable block 509 and the second movable block 510 are relatively vertically staggered and moved up and down. When the second movable block 510 moves upward to the highest position, the driving column 607 squeezes the driving block 604 toward one end on the inner wall of the second movable groove 603, and the driving block 604 drives the connecting shaft 503 to move through the connecting arm 602 and the support frame 601, thereby switching the meshing state of the two driven gears 502 and the face gear 501, so as to change the rotation direction of the connecting shaft 503. On the contrary, when the first movable block 510 moves upward to the highest position, the driving column 607 squeezes the driving block 604 toward one end on the inner wall of the second movable groove 603, and the driving block 604 drives the connecting shaft 503 to move through the connecting arm 602 and the support frame 601, thereby switching the meshing state of the two driven gears 502 and the face gear 501, so as to change the rotation direction of the connecting shaft 503. When block 509 moves to the highest position, the driving block 604 moves in the opposite direction, and switches the meshing state of the two driven gears 502 and the face gear 501 again, so that the driving shaft 401 can continue to rotate by switching the meshing state of the two driven gears 502 with the face gear 501 at different times, thereby realizing the vertical reciprocating up and down movement of the first movable block 509, and then the first movable block 509 drives the connecting tube 511 to move vertically reciprocating up and down, and the connecting tube 511 drives the cleaning component to continuously move back and forth up and down to perform cleaning work.

[0048] Working principle: When in use, the invention first adds microalgae and nutrient solution into the microalgae bioreactor 1, then energizes the drive motor 411, and makes the drive motor 411 drive the drive shaft 401 to rotate, so that the drive shaft 401 drives the heat exchange tube 405 to rotate inside the microalgae bioreactor 1 through the first connecting frame 402 and the annular frame 403, and injects condensed water with waste heat into the liquid inlet pipe 408, and makes the condensed water enter the water inlet cavity of the annular frame 403 through the liquid inlet pipe 408, and enters the water outlet cavity of the annular frame 403 through the heat exchange tube 405, and finally is discharged outward through the liquid outlet pipe 409. Since the middle part of the heat exchange tube 405 is flat, and the horizontal center line of the flat middle part of the heat exchange tube 405 and the midpoint of the fixed column 407 are located on the same straight line, the heat exchange tube 405 can avoid blocking the light of the lamp 412. At the same time, since the middle part of the heat exchange tube 405 is flat, the circulation speed of the condensed water can be slowed down, thereby extending the heat exchange time of the condensed water and improving the heat exchange efficiency. At the same time, when the heat exchange tube 405 rotates inside the microalgae bioreactor 1, the heat can be evenly distributed inside the microalgae bioreactor 1, and the nutrient solution inside the microalgae bioreactor 1 can be rotated to evenly distribute the nutrients.

[0049] When the driving shaft 401 rotates, since the fixed column 407 is fixed at the bottom of the inner wall of the microalgae bioreactor 1, the driving shaft 401 will rotate relative to the fixed column 407, and the driving shaft 401 drives the face gear 501 to mesh with the driven gear 502. When the face gear 501 drives the driven gear 502 to rotate, the driven gear 502 drives the driving roller 504 to rotate through the connecting shaft 503, and the driving roller 504 cooperates with the driven roller 506 to drive the transmission belt 505 to transmit, so that the transmission belt 505 drives the first movable block 509 and the second movable block 510 to move alternately with each other, and the first movable block 509 drives the connecting pipe 511 to move up and down along the direction of the fixed column 407. By providing the guide block 512 and the first guide groove 513, the first movable block 509 and the second movable block 510 can move more stably.

[0050] When the connecting tube 511 moves up and down, the connecting tube 511 drives the cleaning ring 703, the articulated arm 704 and the cleaning rubber sleeve 705 to move up and down through the third connecting frame 701, and the brushes on the inner wall of the cleaning ring 703 and the cleaning rubber sleeve 705 respectively clean the dirt generated by the growth of microalgae on the surface of the heat exchange tube 405 and the lamp tube 412, so as to avoid affecting the light intensity of the lamp tube 412. At the same time, the circumference of the flat structure of the heat exchange tube 405 is equal to the circumference of the top of the heat exchange tube 405, so that the cleaning rubber sleeve 705 can always be closely attached to the surface of the heat exchange tube 405, clean the dirt on the surface of the heat exchange tube 405, and then effectively improve the heat exchange efficiency of the heat exchange tube. By setting the positioning column 702, the movement of the third connecting frame 701 can be guided;

[0051] Since the first movable block 509 and the second movable block 510 are relatively vertically staggered and move up and down, when the second movable block 510 moves upward to the highest position, the second movable block 510 drives the driving column 607 to move upward on the inner wall of the third movable groove 605 through the connecting plate 606, so that the driving column 607 squeezes the driving block 604 to one end on the inner wall of the second movable groove 603, and the driving block 604 drives the connecting shaft 503 to move through the connecting arm 602 and the supporting frame 601, thereby switching the meshing state of the two driven gears 502 and the face gear 501, that is, by switching the meshing state of the two driven gears 502 with the face gear 501 at different times, the rotation direction of the connecting shaft 503 is changed, so that the second movable block 510 After moving to the highest position, the connecting shaft 503 reverses, and drives the transmission belt 505 to transmit in the reverse direction through the driving roller 504, so that the second movable block 510 moves downward, and the first movable block 509 moves upward. Similarly, when the first movable block 509 moves to the highest position, the driving block 604 moves in the reverse direction, thereby switching the meshing state of the two driven gears 502 and the face gear 501 again, so that the driving shaft 401 continuously rotates, and the meshing state of the two driven gears 502 and the face gear 501 is switched at different times, thereby realizing the vertical reciprocating up and down movement of the first movable block 509, and then the first movable block 509 drives the connecting pipe 511 to move vertically reciprocating up and down, and the connecting pipe 511 drives the cleaning component to continuously move reciprocating up and down to perform cleaning work;

[0052] By setting up a power assist component 608, and the power assist component 608 includes a swinging telescopic sleeve and a return spring, when the connecting arm 602 moves and compresses the power assist component 608 to a critical state, that is, at this time, the two driven gears 502 are in a state where they are not meshed with the face gear 501. After the connecting arm 602 continues to move, the return spring in the power assist component 608 will quickly assist the connecting arm 602 to move, so that the two driven gears 502 can quickly switch to a state of meshing with the face gear 501, thereby avoiding the occurrence of unsmooth switching of the meshing state of the two driven gears 502 and the face gear 501.
