[0020] The following will further describe the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and should not be used to limit the protection scope of the present utility model.
[0021] As shown in Figure 1 , Figure 2 , Figure 3As shown in the figure, the utility model is a side fiber optic flowmeter, which includes a base 1, a cavity 2, a gear 3, a gear shaft 4, a gear magnet 5, a lid 6, a flywheel 7, a bearing 8, a flywheel shaft 9, a flywheel cover 10, an optical fiber 11, a capillary 12 and a capillary magnet 13. A cavity 2 is provided on the base 1. A gear 3 is provided inside the cavity 2. A gear shaft 4 and a gear magnet 5 are provided inside the gear 3. A lid 6 is provided on the cavity 2. A flywheel 7 is provided on the lid 6. A bearing 8 is provided inside the flywheel 7. A flywheel shaft 9 is provided inside the bearing 8. A flywheel cover 10 is provided on the lid 6. A penetration hole is provided on the flywheel cover 10. The optical fiber 11 is inserted into the flywheel cover 10 through the penetration hole. A capillary 12 is provided inside the flywheel 7. A capillary magnet 13 is provided on the capillary 12. The gear magnet 5 and the capillary magnet 13 attract each other magnetically across the lid 6.
[0022] It further includes a sealing ring 14. The sealing ring 14 is provided between the base 1 and the cavity 2, and the sealing ring 14 is provided between the cavity 2 and the lid 6.
[0023] The cavity 2 and the base 1 are fixed through a pin 15 and a first screw 16 to form a cavity. The gear shaft 4 positions the gear 3 in the cavity. A gear magnet 5 is installed on the gear 3. The lid 6 covers the gear 3 in the cavity. A flat groove is made on the lid. One end of the capillary 12 is equipped with a capillary magnet 13, corresponding to the gear magnet 5 on the gear 3. The other end is connected to the flywheel 7. The flywheel 7 is equipped with a high-speed bearing and is positioned on the lid 6 by the flywheel shaft 9, and then covered by the flywheel cover 10. The optical fiber 11 enters from the side of the flywheel cover 10, and the infrared light spot shines on the flat surface at one end of the flywheel 7. The lid 6 and the cavity 2 are fixed through a second screw 17. The flywheel cover 10 and the lid 6 are fixed through a third screw 18.
[0024] When the liquid passes through the flowmeter, it drives the internal gear 3 of the flowmeter to rotate. The gear magnet 5 on the gear 3 and the capillary magnet 13 on the capillary 12 are magnetically attracted to each other correspondingly. The rotation of the gear 3 drives the rotation of the flywheel 7. When the flywheel 7 rotates, its own end face turns away and turns back, used to refract the infrared light of the optical fiber 11, and the optical fiber 11 feeds back the signal through the infrared light refraction. Specifically, the optical fiber 11 enters from the side, and the infrared light spot shines on the flat surface at one end of the flywheel 7. The flywheel 7 rotates synchronously with the gear 3 through the capillary magnet 13 on the capillary 12. When the flat surface at one end of the flywheel 7 turns away, the infrared light spot shoots out, and when the flat surface turns back, the infrared light spot refracts and feeds back the signal. In this way, the signal can be captured at high speed without adding a battery to store electricity.
