[0032] The maintenance component includes a lead screw 201 rotatably mounted on the upper flange 102, the lead screw 201 is threadedly matched with the lower flange 106, the lead screw 201 is driven by a drive motor 202, and the drive motor 202 is fixedly mounted on the upper flange 102 through a drive motor bracket 203, a hexagonal prism 204 is fixedly mounted on the output shaft of the drive motor 202, a center wheel 206 is fixedly mounted on the hexagonal prism 204, a socket wrench 205 is sleeved on the outer side of the hexagonal prism 204, a planetary gear 207 is meshed with a gear on the center wheel 206, an outer ring gear 209 is meshed with a gear on the planetary gear 207, the outer ring gear 209 is fixedly connected to the lead screw 201, the planetary gear 207 is rotatably mounted on a planetary gear bracket 208, and the planetary gear bracket 208 is fixedly mounted on the upper flange 102.

[0033] The sealing assembly includes a horizontal plate frame 301 fixedly mounted on the optical axis 105, a through hole is opened on the horizontal plate frame 301, and a magnet column 303 is slidably mounted in the through hole, and two limit claws 304 are magnetically matched on the magnet column 303, and the two limit claws 304 are rotatably mounted on the horizontal plate frame 301 through the limit claw bracket 302, and a vertical pull rod bracket 309 is fixedly mounted on the protective tube 103, and a vertical pull rod 308 is slidably mounted on the vertical pull rod bracket 309 A middle pull rod 310 is movably installed at the bottom end of the vertical pull rod 308, and a rotating pull rod 311 is movably installed on the middle pull rod 310. The rotating pull rod 311 is fixedly installed on the ball valve core 1081, and the ball valve core 1081 is rotatably installed in the ball valve shell 108. A step pin bracket 306 is fixedly installed on the top of the vertical pull rod 308, and a step pin 305 is fixedly installed on the step pin bracket 306. A spring sheet 307 is fixedly installed on the vertical pull rod bracket 309.

[0034] The working principle of an online disassembly and assembly flow meter disclosed in the present invention is as follows: when in use, the user first installs the device vertically on the pipeline through the flange short pipe 109. When liquid flows through the target plate 112, the target plate 112 will hinder the flow of the liquid, and the target plate 112 will be subjected to the force from the liquid. At this time, the sensor 111 will detect the force exerted on the target plate 112, and the flow rate of the liquid can be detected by the size of the force, and then the flow rate can be calculated. When the instrument fails and needs to be repaired, the drive motor 202 is started or the socket wrench 205 is used to drive the hexagonal prism 204 to rotate. When the drive motor 202 is started, the output shaft of the drive motor 202 drives the hexagonal prism 204 to rotate, the hexagonal prism 204 drives the center wheel 206 to rotate, the hexagonal prism 204 drives the planetary gear 207 to rotate, the planetary gear 207 drives the outer ring gear 209 to rotate, and the outer ring gear 209 drives the lead screw 201 to rotate. Since the lead screw 201 is threadedly matched with the lower flange 106, when the lead screw 201 rotates, it will cause the lead screw 201 to move upward. The upward movement of the lead screw 201 will drive the upper flange 102 to move upward. The upward movement of the upper flange 102 will drive the optical axis 105 and the displacement guide tube 110 to move upward. The upward movement of the optical axis 105 will drive the cross plate frame 301 to move upward, and the upper flange 102 moves to the position as shown in the figure. Fig. 9 As shown in the figure, the target plate 112 on the displacement guide tube 110 just moves to the top of the ball valve core 1081 and separates from the ball valve core 1081. At this time, the horizontal plate frame 301 moves to the position as shown in the figure. Fig.10 As shown in the figure, the two limit claws 304 are stuck on the step pin 305, and then continue to move upward, the horizontal plate frame 301 will drive the step pin bracket 306 to move upward, the step pin bracket 306 moves upward, and the vertical rod 308 moves upward, which will drive the middle rod 310 and the rotating rod 311 to move upward. Figure 4Move the position shown to Fig. 9 At this time, the ball valve core 1081 will move from Fig.14 Rotate the position shown to Fig.15 The position shown in the figure cuts off the flow of liquid on both sides of the ball valve housing 108, and the instrument can be repaired at this time.

[0035] When reinstalling the instrument, the displacement guide tube 110 is installed on the upper flange 102 and inserted into the protective tube 103. At this time, the drive motor 202 is started to control the rotation of the lead screw 201, so that the lead screw 201 drives the upper flange 102 to move downward, thereby driving the displacement guide tube 110, the sensor 111 and the target plate 112 to enter the protective tube 103. In the process of the target plate 112 moving to the ball valve shell 108, the magnet column 303 moves downward under the action of gravity, thereby driving the two limit claws 304 to approach each other, and the limit claws 304 will hook the step latch 305 from the like. Fig. 9 Move the position shown to Figure 4 As shown in the position, the ball valve core 1081 will move from Fig.15 Move the position shown to Fig.14 As shown in the figure, the displacement guide tube 110, the sensor 111, and the target plate 112 pass through the ball valve housing 108. Fig.13 As shown, the bottom of the magnet column 303 will contact the spring sheet 307 to give the magnet column 303 an upward force. At this time, the drive motor 202 is reversed to allow the optical axis 105 to move upward for a distance to eliminate the friction between the limit claw 304 and the step surface of the step pin 305. At this time, the magnet column 303 can move upward under the action of the spring sheet 307, and push the two limit claws 304 to separate from the step pin 305, and then the drive motor 202 is rotated forward again to drive the optical axis 105 to move downward. During this process, the spring sheet 307 will continue to give the magnet column 303 an upward force, so the limit claw 304 is always in an open state until the spring sheet 307 is separated from the magnet column 303. At this time, the lead screw 201 continues to rotate to move the target plate 112 to the desired position.
