Description

Technical Field

[0001] This application relates to the technical field of electromagnetic flowmeters, and particularly to an IO-Link electromagnetic flowmeter. Background Art

[0002] Electromagnetic flowmeters are a new type of flow measurement instrument that has developed rapidly with the development of electronic technology. Electromagnetic flowmeters apply the principle of electromagnetic induction and measure the flow rate of conductive fluids based on the electromotive force induced when conductive fluids pass through an externally applied magnetic field.

[0003] After long-term use, some deposits, dirt and other impurities will be generated in electromagnetic flowmeters, and these impurities will affect the accuracy and stability of the instruments.

[0004] However, in the process of implementing related technical solutions, it is found that there are at least the following technical problems: First, these failures are often caused by the conductivity of the adhesion layer being too large or too small. If the adhesion is an insulating layer, the electrode circuit will be open and the instrument cannot work properly; if the conductivity of the adhesion layer is significantly higher than that of the fluid, the electrode circuit will be short-circuited and the instrument cannot work properly either. Therefore, the adhesion layer in the electromagnetic flowmeter needs to be cleaned in real time to ensure the accuracy of the electromagnetic flowmeter. Second, not only the adhesion layer in the electromagnetic flowmeter needs to be cleaned, but also the electrical measurement windings and electrodes in the electromagnetic flowmeter need to be cleaned in time. Only through multiple cleaning actions can the measurement data of the electromagnetic flowmeter be more accurate. Summary of the Invention

DETAILED DESCRIPTION

[0037] The embodiment of the present application discloses an IO-Link electromagnetic flowmeter. The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] Embodiment 1

[0040] Reference Figures 1-3, an IO-Link electromagnetic flowmeter, including an IO-Link electromagnetic flowmeter body 100. A liner tube 200 is provided inside the IO-Link electromagnetic flowmeter body 100. The present invention adopts an IO-Lin transmission module. O-Link is a point-to-point serial communication protocol and a low-cost communication interface technology for integrating traditional or intelligent sensors and actuators into an automation system. Having an "IO-Link" communication interface enables on-site sensors to better adapt to the need for simple and quick modification of parameter settings, and will have great flexibility during the production process, thus being able to better serve the detection work of the IO-Link electromagnetic flowmeter. It also includes a primary cleaning unit 1 provided on the liner tube 200 for filtering the liquid flowing into the liner and cleaning the outside of the liner at the same time. The primary cleaning unit 1 includes a filtering component 11 concentrically arranged with the liner tube 200 for filtering the liquid flowing into the liner tube 200 and cleaning the end of the liner tube 200. The filtering component 11 abuts against a primary cleaning component 10 for driving the primary cleaning component 10 to repeatedly clean the outer wall of the liner tube 200 when the filtering component 11 rotates;

[0041] The primary cleaning component 10 includes a bottom cleaning part 12 provided outside the liner tube 200 for repeatedly cleaning half of the circumferential direction of the liner tube 200. An upper cleaning part 13 for repeatedly cleaning the remaining half of the circumferential direction of the liner tube 200 is provided outside the bottom cleaning part 12;

[0042] Using the filtering component 11 can directly reduce the entry of impurity-containing liquid into the inside of the liner tube 200, avoid the entry of liquid containing impurities into the liner tube 200, and reduce the errors in the detection of the IO-Link electromagnetic flowmeter. While the filtering component 11 is operating, it can drive the primary cleaning component 10 to indirectly clean the impurities on the outer wall of the liner tube 200.

[0043] Refer to Figures 3-6 , the filtering component 11 includes a filter plate 111 fixedly provided at the water inlet end inside the liner tube 200, and a rotating shaft 112 is concentrically provided on the filter plate 111. The rotating shaft 112 is driven by a first power device, which is preferably a motor. The first power device is installed outside a second mounting ring 131 (not marked in the figure). A cleaning plate 114 is movably provided in the circumferential direction of the rotating shaft 112, and bristles are provided on the cleaning plate 114. A pressing plate 115 is movably provided along the height direction of the rotating shaft 112, and the pressing plate 115 is located above the cleaning plate 114. A first elastic member 116 for elastically stretching the cleaning plate 114 on the filter plate 111 is provided between the pressing plate 115 and the cleaning plate 114. The first elastic member 116 is preferably a spring;

[0044] It should be noted that the filter plate 111 is provided with filter holes. The holes of the filter holes are relatively large, which can filter large impurities. The large impurities will cause collisions to parts of the IO-Link electromagnetic flowmeter body 100, thereby damaging the IO-Link electromagnetic flowmeter body 100. Since the holes of the filter holes are relatively large, it does not affect the flow rate of the liquid passing through, so that the influence of the filter plate on the flow rate of the liquid measured by the IO-Link electromagnetic flowmeter body 100 can be ignored.

[0045] Refer to Figure 3 and Figures 5-9 As shown in and, the bottom cleaning part 12 includes a first mounting ring 121 fixedly installed on the outside of the lining sleeve 200. A first moving track 122 is provided on the first mounting ring 121. A first cleaning brush 123 is slidably connected in the first moving track 122 through a moving column. A first abutting block 124 is rotatably connected to one side of the first cleaning brush 123 close to the end of the lining sleeve 200. The first abutting block 124 is in contact connection with the cleaning plate 114. A first limiting track 125 is fixedly connected to the end of the lining sleeve 200. The first limiting track 125 is provided with a first disengaging part 126. The first limiting track 125 and the first abutting block 124 are connected through a first limiting column 127. A second elastic member 128 is fixedly connected between the first mounting ring 121 and the first abutting block 124, which is used to make the first abutting block 124 follow the cleaning plate 114 to move along the first mounting ring 121 to the first disengaging part 126 and then drive the first abutting block 124 to return to the initial position. The second elastic member 128 is preferably an arc-shaped spring;

[0046] Refer to Figure 3 and Figures 10-13, the top cleaning part 13 includes a second mounting ring 131 fixedly installed outside the first mounting ring 121, and a second moving track 132 is provided on the second mounting ring 131. A second cleaning brush 133 is slidably connected in the second moving track 132 through a moving column. One side of the second cleaning brush 133 close to the end of the lining sleeve 200 is rotatably connected with a second abutting block 134. The second abutting block 134 is in contact connection with the cleaning plate 114. A second limiting track 135 is symmetrically provided with the first limiting track 125 at the end of the lining sleeve 200, and a second disengaging part 136 is provided on the second limiting track 135. The second limiting track 135 and the second abutting block 134 are connected through a second limiting column 137. A third elastic member 138 is fixedly connected between the second mounting ring 131 and the second abutting block 134, which is used to drive the second abutting block 134 to return to the initial position after the second abutting block 134 follows the cleaning plate 114 and moves along the second mounting ring 131 to the second disengaging part 136. The third elastic member 138 is preferably an arc-shaped spring, and guiding sliding surfaces 139 are provided at one ends of the first abutting block 124 and the second abutting block 134 close to the cleaning plate 114 and the pressing plate 115 respectively;

[0047] The IO-Link electromagnetic flowmeter body 100 is installed perpendicular to the water flow direction. When the IO-Link electromagnetic flowmeter body 100 performs flow detection, the first power device drives the rotating shaft 112 to rotate to generate power, and the pressing plate 115 and the cleaning plate 114 on the rotating shaft 112 both perform circular motion together. There is a height difference between the pressing plate 115 and the cleaning plate 114, and the pressing plate 115 can slide along the height direction of the rotating shaft 112 on the rotating shaft 112, that is, it can act on the cleaning plate 114 together with the first elastic member 116. Thus, while the cleaning plate 114 rotates with the rotating shaft 112, the brush on the cleaning plate 114 cleans the filter plate 111, and cooperates with the pressing plate 115 to slide and remove impurities in the height direction of the rotating shaft 112. The impurities separated from the filter plate 111 will flow away from the gap between the IO-Link electromagnetic flowmeter body 100 and the lining sleeve 200, and under the action of the pressing plate 115 and the first elastic member 116, the impurities can be removed in a state of being loosened and tightened, so as to achieve a better impurity removal effect on the filter plate 111;

[0048] On the other hand, while the pressing plate 115 and the cleaning plate 114 perform circular motion with the rotating shaft 112, they can respectively drive the first abutting block 124 and the second abutting block 134 to perform circular motion together;

[0049] The rotating shaft 112 rotates clockwise, causing the cleaning plate 114 to first come into contact with the first abutting block 124. Since the first cleaning brush 123 is jointly restricted by the moving column and the first abutting block 124 within the first limiting track 125 through the first limiting column 127, the cleaning plate 114 pushes the first abutting block 124 to perform a half-circle movement around the center of the bushing 200. At this time, the second elastic member 128 is stretched along the trajectory of the first mounting ring 121. The initial position of the second elastic member 128 is the normal state, and the first cleaning brush 123 rotatably connected to the first abutting block 124 acts on the outer wall of the bushing 200 and moves together with the movement of the first abutting block 124. Thus, the first cleaning brush 123 positively cleans half of the outer wall at the bottom of the bushing 200;

[0050] When the cleaning plate 114 pushes the first abutting block 124 to reach the disengaging portion of the first limiting track 125, the disengaging portion is set as an arc gradually deviating from the arc of the first limiting track 125. When the first limiting column 127 on the first abutting block 124 moves to the disengaging portion, it gradually moves away from the cleaning block until the first abutting block 124 can rotate through the guiding sliding surface 139 during the continuous movement, thereby releasing the pushing action of the cleaning block on the first abutting block 124 and enabling it to continue to perform a circular movement around the center of the bushing 200;

[0051] After the first abutting block 124 is disengaged from the cleaning block, the second elastic member 128 is stretched to the maximum state. Under the action of the elastic restoring force of the second elastic member 128, the first limiting column 127 on the first abutting block 124 gradually slides back into the first limiting track 125 from the disengaging portion. And during this restoring process, the first cleaning brush 123 reversely cleans half of the outer wall at the bottom of the bushing 200 again, thereby realizing one positive cleaning and one reverse cleaning of half of the outer wall of the bushing 200 in one cycle. Such repeated cleaning is one cycle, so that the cleaning effect of the first cleaning brush 123 on the bushing 200 is better. And there is another advantage of using the second elastic member 128, that is, during the rebounding process of the first abutting block 124, the first cleaning brush 123 has a buffering effect and vibrates when contacting the bushing 200, so that the impurities on the first cleaning brush 123 can be shaken off, reducing the impurities adhering to the first cleaning brush 123 during long-term use;

[0052] The second cleaning brush 133 operates in the same state as the first cleaning brush 123. At the moment when the cleaning plate 114 is separated from the first abutment block 124, the holding plate 115 contacts the second abutment block 134, and the holding plate 115 and the cleaning plate 114 continue to follow the rotating shaft 112 for circular motion, so that the second abutment block 134 drives the second cleaning brush 133 to move along the second limiting track 135 and the second movable track 132 in the second mounting ring 131 respectively. The movement process is the same as above, except that the second abutment block 134 is pushed and moved by the holding plate 115, that is, the remaining half of the outer wall at the top of the bushing tube 200 can be cleaned by the second cleaning brush, and it can also be cleaned alternately in forward and reverse directions, thereby achieving comprehensive cleaning of the bushing tube 200.

[0053] Embodiment 2

[0054] Reference Figures 1-3 A re-cleaning unit 2 for cleaning the electromagnetic winding and the electrode is provided between the IO-Link electromagnetic flowmeter and the liner tube 200. The re-cleaning unit 2 includes a magnetic cleaning component 21 provided on the IO-Link electromagnetic flowmeter body 100 for moving and comprehensively cleaning the electromagnetic winding. A pole cleaning component 22 is provided at one end of the primary cleaning component 10 for wiping the electrode end while the filter component 11 rotates.

[0055] The magnetic cleaning component 21 and the pole cleaning component 22 can directly clean the electromagnetic winding comprehensively to reduce impurities on the electromagnetic winding, and can roughly clean the electrode while cleaning the electromagnetic winding, so that the impurities do not affect the normal use of the electrode.

[0056] Reference Figures 14-17 The electrode cleaning assembly 22 includes a toggle block 221 which is respectively rotatably arranged outside the first cleaning brush 123 and the second cleaning brush 133, and a wiping block 222 is arranged outside the toggle block 221 for cleaning the electrode end when following the rotation of the first cleaning brush 123 and the second cleaning brush 133;

[0057] The magnetic cleaning component 21 includes an arc plate 211 disposed on the IO-Link electromagnetic flowmeter body 100, and an arc groove 212 is opened in the arc plate 211, a first rack 213 is slidably connected in the arc groove 212, and the first rack 213 is in contact with the toggle block 221, a first cleaning cotton 214 is disposed at the end of the first rack 213, and a fourth elastic member 215 is fixedly connected between the first rack 213 and the arc plate 211, and the fourth elastic member 215 is preferably a spring, IO -Link electromagnetic flowmeter body 100 is rotatably connected with a rotating gear 216, and the rotating gear 216 is meshed with the first rack 213. A second rack 217 is slidably connected with the IO-Link electromagnetic flowmeter body 100, and the second rack 217 is arranged on a side opposite to the first rack 213 and meshed with the rotating gear 216, and the end of the second rack 217 is arranged on the second cleaning cotton 218, the first rack 213 is an arc rack, and the second rack 217 is a straight rack;

[0058] Taking the second abutment block 134 moving along the top half arc path of the bushing tube 200 under the push of the holding plate 115 as an example, when the second abutment block 134 moves, the second cleaning brush 133 moves together, the toggle block 221 and the wiping block 222 on the second cleaning move together, and the toggle block 221 and the second cleaning brush 133 are rotationally connected through a torsion spring. When the second cleaning brush 133 moves to the position of the first rack 213, the toggle block 221 contacts one end of the first rack 213 and pushes the first rack 213 to The fourth elastic member 215 is in a normal state at this time. With the movement of the first rack 213, the fourth elastic member 215 is in a compressed state. When the first rack 213 moves, the rotating gear 216 meshing with the first rack 213 rotates counterclockwise. The counterclockwise rotation of the rotating gear 216 can drive the second rack 217 to move toward the electromagnetic winding, so that the first cleaning cotton 214 and the second cleaning cotton 218 respectively wipe and clean the end and both sides of the electromagnetic winding.

[0059] As the second cleaning brush 133 continues to rotate, the second cleaning brush 133 pushes the first rack 213 to move to the position closest to the rotating gear 216. At this time, the fourth elastic member 215 is compressed to the limit, causing the first rack 213 to no longer be able to move. However, the second cleaning brush 133 still continues to move, causing the toggle block 221 to rotate, so as to avoid contact with the toggle block 221. At this time, two-directional movements occur. One is that under the resilience of the fourth elastic member 215, the first rack 213 moves in a direction away from the electromagnetic winding, thereby driving the first cleaning cotton 214 to wipe the electromagnetic winding in the reverse direction again. The rotating gear 216 rotates clockwise, driving the second rack 217 to move in a direction away from the electromagnetic winding, so as to wipe the electromagnetic winding again, realizing repeated wiping of the electromagnetic winding. The second cleaning brush 133 continues to move until it reaches the electrode position and contacts the electrode, thereby cleaning the end of the electrode;

[0060] During the process of detecting the flow rate, the first power device can enable the rotating shaft 112 to continuously perform circular motion. The rotation of the rotating shaft 112 means that the cleaning plate 114 and the pressing plate 115 continuously perform circular motion;

[0061] And as long as the cleaning plate 114 and the pressing plate 115 continuously perform circular motion, they can keep cleaning the outer wall, inner diameter of the liner tube 200, as well as the electromagnetic winding and the electrode, thereby realizing comprehensive cleaning of the IO-Link electromagnetic flowmeter body 100 and ensuring the accuracy of liquid flow rate detection during use;

[0062] It should be noted that the electrode cannot be cleaned in detail because the electrode is extremely precise and it is not suitable to perform thorough cleaning on it during use, as it is likely to cause damage.

[0063] The working principle of this application:

[0064] Filtration and cleaning: Driven by the first power device, the rotating shaft 112 generates power. While allowing the liquid to pass through the filter plate 111 into the liner tube 200 for speed measurement, it uses the rotation of the cleaning plate 114 and the pressing plate 115 to clean the impurities on the filter plate 111;

[0065] The outer wall of the bushing tube 200 is cleaned. As the cleaning plate 114 and the holding plate 115 make circular motions, the first abutment block 124 and the second abutment block 134 are driven to move respectively, so that the first cleaning brush 123 and the second cleaning brush 133 are used to clean the outer wall of the bushing tube 200 in a positive direction. After the cleaning plate 114 and the holding plate 115 release the push of the first cleaning brush 123 and the second cleaning brush 133 respectively, the first cleaning brush 123 and the second cleaning brush 133 can respectively clean the bushing tube 200 in a reverse direction under the elastic restoring force of the second elastic member 128 and the third elastic member 138, and can vibrate the first cleaning brush 123 and the second cleaning brush 133 under the action of the rebound force to remove impurities.
