[0002] The metal pipe float flow meter is an instrument for monitoring fluid flow and is widely applied in various industrial fields. The working principle of the metal pipe float flow meter is based on the balance of fluid power, buoyancy and self weight of a float in a vertical conical pipe.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0030] Please refer to Figures 1-8 The application provides a technical solution: a metal pipe float flowmeter based on an intelligent sensor, which comprises a pipe body 1 and a detection mechanism 4, a instrument 2 is fixed on the outer side of the pipe body 1 through bolts to realize flow display, the instrument 2 and a Hall element 3 are connected with each other, and the pipe body 1 is internally provided with the detection mechanism 4 for flow detection,

[0031] The locking mechanism 5 is used to initially lock the detection mechanism 4 and can effectively reduce the initial jamming of the detection mechanism 4. The locking mechanism 5 is connected to the detection mechanism 4.

[0032] The control mechanism 6 is used to buffer the fluid and reduce the direct impact of fluid flow changes on the detection mechanism 4, which would cause the float body 403 to jump violently. The control mechanism 6 is installed inside the tube body 1.

[0033] The lower end of the pipe body 1 is fixed with an inlet flange 101, and the upper end of the pipe body 1 is fixed with an outlet flange 102. An adjusting seat 103 is fixed inside the pipe body 1.

[0034] When using a metal tube float flowmeter based on a smart sensor, such as Figures 1-8 As shown, the entire device is first installed and fixed to the fluid pipeline by using the inlet flange 101 and outlet flange 102 with bolts, ensuring that the fluid enters the pipe body 1 through the inlet flange 101 and is discharged through the outlet flange 102. At this time, the card seat 503 and the positioning block 407 are in a locked state, realizing the locking function of the float body 403 and ensuring the stability of the float body 403 in a static state.

[0035] A lower guide rod 405 is fixed to the lower end of the float body 403, and the lower guide rod 405 is slidably connected to the lower support 406. The lower support 406 is fixed inside the tube body 1. A positioning block 407 is fixed to the lower end of the lower guide rod 405, and the end of the positioning block 407 has an arc surface structure. Triangular strip plates 408 are symmetrically fixed to the left and right sides of the lower end face of the positioning block 407, and the height of the triangular strip plates 408 is 1mm-3mm. The locking mechanism 5 includes a fixing rod 501 that is fixed to the lower support 406, and a crossbar 502 is slidably connected to the fixing rod 501. The rod 502 and the card holder 503 are fixed to each other, and the card holder 503 and the positioning block 407 are engaged. The upper surface of the card holder 503 is a sloping structure, and a first spring 504 is fixed between the card holder 503 and the fixed rod 501. A top plate 505 is also fixed on the card holder 503, and the top plate 505 and the triangular strip plate 408 are slidably connected. The horizontal distance between the top plate 505 and the triangular strip plate 408 is equal to the distance from the end of the card holder 503 to the end of the positioning block 407. An "L"-shaped adjusting rod 506 is also fixed at the lower end of the card holder 503.

[0036] After the installation of the device is completed, the solid passes through the liquid inlet flange 101, at this time the fluid first generates the force used for the sealing sleeve 607, so that the sealing sleeve 607 is forced to start moving up, with the sliding action between the vertical rod 605 and the horizontal plate 604, can ensure the stability of the sealing sleeve 607 movement, when the sealing sleeve 607 moves up, the synchronous belt drives the inclined plate 608 to move up, with the sliding action between the inclined plate 608 and the adjusting rod 506, can make the adjusting rod 506 drive the clamping seat 503 to move to both sides, with the sliding action between the horizontal rod 502 and the fixed rod 501, can ensure the stability of the clamping seat 503 movement, in the process of moving the clamping seat 503, when the upper side of the clamping seat 503 separates from the positioning block 407, so that the locking effect of the float body 403, and at this time the top plate 505 and the triangular strip plate 408 are in contact, when the inclined plate 608 and the adjusting rod 506 continue to slide, at this time the clamping seat 503 continues to move, thereby driving the top plate 505 to continue to move, when the sliding action between the top plate 505 and the triangular strip plate 408, makes the positioning block 407, the lower guide rod 405, the float body 403 and the upper guide rod 402 move up synchronously, with the sliding guide action between the lower support 406 and the lower guide rod 405 and the sliding guide action between the upper support 401 and the upper guide rod 402, can ensure the stability of the float body 403 movement, so that the float body 403 and the adjusting seat 103 are separated, when the top plate 505 and the triangular strip plate 408 are separated, at this time under the action of the self weight of the float body 403, makes the float body 403 automatically reset and contact with the adjusting seat 103, so as to realize the float body 403 one time and reset effect, effectively remove the float body 403 and the adjusting seat 103 between the sticky state, in order to subsequent detection effect;

[0037] The detection mechanism 4 comprises an upper support 401 fixed with the pipe body 1, and the upper support 401 and the upper guide rod 402 are in sliding connection, and the upper guide rod 402 and the float body 403 are fixed with each other, and the float body 403 and the adjusting seat 103 cooperate to realize the sealing effect; the float body 403 is fixed with a permanent magnet steel 404, and the permanent magnet steel 404, the hall element 3 and the instrument 2 cooperate to form a magnetic sensitive sensor for realizing flow detection;

[0038] When the float body 403 moves back to the reset position, the sealing sleeve 607 always seals the opening 603 at this time, thereby avoiding the fluid from contacting the float body 403 when the float body 403 is pre-lifted back to the reset position. When the top plate 505 is separated from the triangular strip plate 408 after the pre-lifted reset of the float body 403 is completed, the adjusting rod 506 is in contact with the plane of the inclined plate 608 at this time, and the lower end surface of the sealing sleeve 607 is in contact with the lower end surface of the opening 603 at this time. Under the action of the airflow, the sealing sleeve 607 continues to move upward. When the sealing sleeve 607 removes the shielding of the opening 603, the fluid contacts the float body 403 through the opening 603 at this time. Through the action of the fluid, the push effect on the float body 403 is realized, so that the float body 403 moves under the action of the fluid. When the float body 403 moves, the permanent magnet steel 404 in the float body 403 is driven to move synchronously, so that the magnetic field around the permanent magnet steel 404 changes. The Hall element 3 can detect the magnetic field change of the permanent magnet steel 404 and output the corresponding electric signal, thereby realizing the flow detection effect (the higher the position of the permanent magnet steel 404, the stronger the magnetic field, and the higher the voltage; the lower the position of the permanent magnet steel 404, the weaker the magnetic field, and the lower the voltage). The electric signal is converted into fluid flow information by the instrument 2 and displayed for the staff to check.

[0039] The regulating mechanism 6 comprises a fixed ring 601 fixed with the pipe body 1, a convex ring 602 fixed on the fixed ring 601, a plurality of openings 603 equally angularly arranged on the convex ring 602 for discharging fluid, a horizontal plate 604 fixed in the convex ring 602, a vertical rod 605 slidingly connected to the horizontal plate 604, a second spring 606 having one end fixed with the vertical rod 605 and the other end fixed with the horizontal plate 604, a sealing sleeve 607 fixed on the upper end of the vertical rod 605 and slidingly connected to the outside of the convex ring 602, an inclined plate 608 fixed on the upper end surface of the sealing sleeve 607 and slidingly connected with the adjusting rod 506, and the height of the inclined surface of the inclined plate 608 is equal to the height from the lower end surface of the sealing sleeve 607 to the lower end surface of the opening 603.

[0040] During the use of the device, when the fluid pushes the sealing sleeve 607 to move to open the opening 603, at this time the second spring 606 is in a force-contracted state, when the fluid flow rate is large, the force generated by the fluid on the sealing sleeve 607 increases, so that the distance of the movement of the sealing sleeve 607 is greater, so that the area of the opening 603 blocked by the sealing sleeve 607 is smaller, that is, the fluid flow space is larger, the active speed reduction of the fluid is realized, on the contrary, when the fluid flow rate decreases, at this time under the action of the second spring 606, the area of the opening 603 blocked by the sealing sleeve 607 increases, the speed of the fluid is increased, through the cooperation of the sealing sleeve 607, the second spring 606 and the opening 603, the regulation effect of the fluid flow rate can be effectively realized, so as to ensure that the pulsating flow of the fluid is converted into a smooth flow, and then the direct impact of the fluid on the float body 403 is effectively reduced, and the accuracy of the fluid flow detection is effectively ensured.
