DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, the utility model provides an interactive teaching device for scientific labor education, including a ladder frame 1, the top of the ladder frame 1 is connected to the shell 2 by a threaded bolt, and a rotating shaft 3 is provided inside the shell 2, and a fan 24 is sleeved on the left side of the rotating shaft 3. When the fan 24 rotates, the rotating shaft 3 rotates, and the rotating shaft 3 drives the driving gear 4 on the outside to rotate. The outer side of the driving gear 4 meshes and rotates with the driven gear 5, and the outer side of the driven gear 5 is fixedly connected to the rotating arm 12. When the driven gear 5 rotates, the rotating arm 12 rotates around the driven gear 5. A connecting rod 11 is provided inside the top of the rotating arm 12, and the other end of the connecting rod 11 passes through the inside of the pulley 8. The pulley 8 slides up and down inside the slide rail 7, driving the outer side of the pulley 8 to slide up and down. The bottom end of the support rod 9 is fixed with a connecting rod 10 by welding. The outer side of the connecting rod 10 passes through the inner center position of the base 6, and the connecting rod 10 slides up and down inside the base 6. The bottom end of the base 6 fits into the inside of the shell 2.

[0025] Specifically, the right side of the rotating shaft 3 is fixedly connected to the rotor 14, and the rotor 14 is magnetically connected to the stator 15. The rotation of the stator 15 and the rotor 14 generates electricity that is transmitted to the top outer generator 13. The rotor 14 is set to rotate inside the generator 13 and transmits electricity to the inside of the battery 17 through the converter 16.

[0026] Furthermore, a water pipe 18 is sleeved on the outer side of the connecting rod 10, and the connecting rod 10 slides up and down inside the water pipe 18, which can draw a vacuum into the inside of the water pipe 18. Drainage grooves are provided on the upper and lower sides of the first blocking plate 19. A first resisting ball 20 is slidingly provided at the inner center position of the first blocking plate 19. The shape of the first resisting ball 20 is larger than the drainage groove of the first blocking plate 19. The connecting rod 10 drives the first blocking plate 19 at the bottom end to slide up and down inside the water pipe 18. When the first blocking plate 19 slides upward, the first resisting ball 20 inside the first blocking plate 19 blocks the first blocking plate 19, and at this time the interior is drawn into negative pressure.

[0027] Furthermore, a water outlet is provided on the outside of the water pipe 18 , and water enters the interior of the water pipe 18 through the filter mesh 21 . The filter mesh 21 is used to intercept impurities and prevent the water pipe 18 from being blocked.

[0028] It is worth noting that a second blocking plate 22 is fixedly connected to the top of the water filter net 21. Drain holes are provided on the upper and lower sides of the second blocking plate 22. A second tightening ball 23 is tightly arranged inside the drainage hole of the second blocking plate 22. The second tightening ball 23 slides on the upper and lower sides of the second blocking plate 22 to block the flow of water. Water enters the interior of the water pipe 18 from the drainage groove of the second blocking plate 22. Through continuous reciprocating motion, each movement of the connecting rod 10 moves the water upward, and finally the water is pumped out.

[0029] It is worth noting that a wind vane 26 is installed on the top of the shell 2 to facilitate viewing the direction of the wind. A display board 25 is installed on the top of the shell 2. The display board 25 is used to place theoretical knowledge teaching materials to facilitate the combination of theory and practice.

[0030] It is worth mentioning that the outer side of the battery 17 is made of waterproof material, which is convenient for outdoor use, and the fan 24 is made of carbon fiber material, which is lighter and has less resistance during operation.

[0031] It is worth emphasizing that the driving gear 4 , the driven gear 5 and the rotating arm 12 are provided in two groups, so that the connecting rod 10 is more stable when performing piston motion inside the water pipe 18 .

[0032] Among them, the battery 17 is the existing technology and will not be described in detail. At the same time, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the figure is the reference.

[0033] Working principle:

[0034] First, the instructor places the ladder frame 1 on the river bank with a height difference, and inserts the water pipe 18 at the bottom end of the shell 2 below the water surface, and places the water outlet of the water pipe 18 above the water surface. When the wind blows to the outside of the fan 24, the fan 24 drives the rotating shaft 3 inside the shell 2 to rotate. At this time, the rotor 14 connected to the rotating shaft 3 rotates inside the generator 13. The rotor 14 and the stator 15 rotate, thereby converting mechanical energy into electrical energy. The generated electrical energy is stored in the battery 17 through the converter 16. The driving gear 4 on the side of the rotating shaft 3 rotates, and the driving gear 4 drives the driven gear 5 on the outside to rotate. At this time, the rotating arm 12 at the front end of the driven gear 5 makes a circular motion. The rotating arm 12 drives the pulley 8 inside the support rod 9 connected to the connecting rod 11 to slide up and down inside the slide rail 7, and the connecting rod 10 at the bottom end of the support rod 9 slides up and down inside the base 6;

[0035] The connecting rod 10 drives the first blocking plate 19 at the bottom to slide up and down inside the water pipe 18. When the first blocking plate 19 slides upward, the first blocking ball 20 inside the first blocking plate 19 blocks the first blocking plate 19. At this time, the interior is pumped into negative pressure, and then the water flows toward the top through the water filter net 21 inside the water pipe 18. Then, the water is affected by atmospheric pressure, and the water squeezes the second tightening ball 23 inside the second blocking plate 22 and pushes it upward. The water enters the interior of the water pipe 18 from the drainage groove of the second blocking plate 22. Through continuous reciprocating motion, each movement of the connecting rod 10 pushes the water upward, and finally the water is pumped out.
