Description

Technical Field

[0001] The present application relates to the technical field of electromagnetic flowmeters, and in particular to an IO-Link electromagnetic flowmeter. Background Art

[0002] Electromagnetic flowmeter is a new type of flow measurement instrument that has developed rapidly along with the development of electronic technology. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluid based on the induced electromotive force when the conductive fluid passes through an external magnetic field.

[0003] After long-term use, the electromagnetic flowmeter will produce some sediment, dirt and other impurities, which will affect the accuracy and stability of the instrument.

[0004] However, in the process of implementing relevant technical solutions, it was found that at least the following technical problems exist: First, these faults are often caused by the electrical conductivity of the attachment layer being too large or too small. If the attachment is an insulating layer, the electrode circuit will be open and the meter will not work normally; if the electrical conductivity of the attachment layer is significantly higher than the electrical conductivity of the fluid, the electrode circuit will be short-circuited and the meter will not work normally. Therefore, the attachment layer in the electromagnetic flowmeter must be cleaned in real time to ensure the accuracy of the electromagnetic flowmeter. Second, not only the attachment layer in the electromagnetic flowmeter needs to be cleaned, but also the electrical measuring windings and electrodes in the electromagnetic flowmeter need to be cleaned in time.

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.

[0021] 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.

[0022] Embodiment 1 Reference Figure 1-Figure 3, an IO-Link electromagnetic flowmeter, including an IO-Link electromagnetic flowmeter body 100, wherein a bushing tube 200 is arranged in 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 is a low-cost communication interface technology that integrates traditional or intelligent sensors and actuators in an automation system. With an "IO-Link" communication interface, field sensors can better adapt to the need for simple and quick modification of parameter settings, and have great flexibility in the production process , so as to better serve the detection work of the IO-Link electromagnetic flowmeter, and also includes a primary cleaning unit 1 arranged on the bushing tube 200 for filtering the liquid passed into the bushing and cleaning the outside of the bushing at the same time, the primary cleaning unit 1 includes a filter assembly 11 arranged concentrically with the bushing tube 200 for filtering the liquid passed into the bushing tube 200 and cleaning the end of the bushing tube 200, and the filter assembly 11 is abutted with a primary cleaning assembly 10 for driving the primary cleaning assembly 10 to repeatedly clean the outer wall of the bushing tube 200 when the filter assembly 11 rotates; The primary cleaning assembly 10 includes a bottom cleaning portion 12 disposed outside the liner tube 200 for repeatedly cleaning one half of the circumferential direction of the liner tube 200, and a top cleaning portion 13 disposed outside the bottom cleaning portion 12 for repeatedly cleaning the remaining one half of the circumferential direction of the liner tube 200; The use of the filter component 11 can directly reduce the amount of liquid with impurities entering the interior of the bushing tube 200, prevent the amount of liquid containing impurities from entering the bushing tube 200, and reduce the error in IO-Link electromagnetic flowmeter detection. While the filter component 11 is running, it can drive the initial cleaning component 10 to indirectly clean the outer wall of the bushing tube 200 of impurities.

[0023] Reference Figure 3-Figure 6 The filter assembly 11 includes a filter plate 111 fixedly arranged at one end of the liner tube 200 entering the water, and a rotating shaft 112 is coaxially arranged on the filter plate 111, and the rotating shaft 112 is driven by a first power device, and the first power device is preferably a motor, and the first power device is installed on the outside of the second mounting ring 131, which is not marked in the figure. A cleaning plate 114 is movably arranged in the circumferential direction of the rotating shaft 112, and bristles are arranged on the cleaning plate 114. A holding plate 115 is movably arranged on the rotating shaft 112 along its height direction, and the holding plate 115 is located at the top of the cleaning plate 114. A first elastic member 116 for elastically extending and retracting the cleaning plate 114 on the filter plate 111 is arranged between the holding plate 115 and the cleaning plate 114, and the first elastic member 116 is preferably a spring; It should be noted that filter holes are provided on the filter plate 111. The holes of the filter holes are relatively large and can filter large impurities. Large impurities may collide with 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, the flow rate of the liquid entering is not affected, so that the influence of the filter plate on the flow rate of the liquid measured by the IO-Link electromagnetic flowmeter body 100 is negligible.

[0024] Reference Figure 3 and Figure 5-Figure 9 The bottom cleaning part 12 includes a first mounting ring 121 fixedly mounted on the outside of the bushing tube 200, and a first movable track 122 is provided on the first mounting ring 121. A first cleaning brush 123 is slidably connected in the first movable track 122 through a movable column, and a first abutment block 124 is rotatably connected to the side of the first cleaning brush 123 close to the end of the bushing tube 200. The first abutment block 124 is abutted against the cleaning plate 114, and the end of the bushing tube 200 is fixedly connected to the first limiting track The first limiting track 125 is provided with a first disengaging portion 126, the first limiting track 125 is connected to the first abutting block 124 through a first limiting column 127, and a second elastic member 128 is fixedly connected between the first mounting ring 121 and the first abutting block 124, which is used to drive the first abutting block 124 to return to the initial position after the first abutting block 124 follows the cleaning plate 114 and moves along the first mounting ring 121 to the first disengaging portion 126. The second elastic member 128 is preferably an arc spring; Reference Figure 3 and Figure 10-13 The top cleaning part 13 includes a second mounting ring 131 fixedly mounted on the outside of the first mounting ring 121, and a second movable track 132 is provided on the second mounting ring 131, a second cleaning brush 133 is slidably connected in the second movable track 132 through a movable column, and a second abutment block 134 is rotatably connected to the side of the second cleaning brush 133 close to the end of the bushing tube 200, and the second abutment block 134 is in contact with the cleaning plate 114, and a second limiting track 135 is symmetrically provided at the end of the bushing tube 200 and the first limiting track 125, and the second limiting track 135 is provided with a second The second disengagement portion 136, the second limiting rail 135 is connected to the second abutment block 134 through a second limiting column 137, and a third elastic member 138 is fixedly connected between the second mounting ring 131 and the second abutment block 134, which is used to make the second abutment block 134 follow the cleaning plate 114 and move along the second mounting ring 131 to the second disengagement portion 136, and then drive the second abutment block 134 to return to the initial position, the third elastic member 138 is preferably an arc spring, and the first abutment block 124 and the second abutment block 134 are respectively provided with a guide sliding surface 139 at one end close to the cleaning plate 114 and the holding plate 115; The IO-Link electromagnetic flowmeter body 100 is installed perpendicular to the direction of the water flow. When the IO-Link electromagnetic flowmeter body 100 is performing flow detection, the first power device drives the rotating shaft 112 to rotate to generate power, and the holding plate 115 and the cleaning plate 114 on the rotating shaft 112 both perform circular motions together, and there is a height difference between the holding plate 115 and the cleaning plate 114, and the holding plate 115 can slide on the rotating shaft 112 along the height direction of the rotating shaft 112, that is, it can work together with the first elastic member 116 on the cleaning plate 114, so that the cleaning plate 114 rotates with the rotating shaft 112, and the brush on the cleaning plate 114 cleans the filter plate 111, and cooperates with the holding plate 115 to slide and remove impurities in the height direction of the rotating shaft 112, and the impurities separated from the filter plate 111 will flow away from the gap between the IO-Link electromagnetic flowmeter body 100 and the bushing tube 200, and under the action of the holding plate 115 and the first elastic member 116, the impurities can be removed in a loose and tight state, so as to achieve a better impurity removal effect on the filter plate 111; On the other hand, the holding plate 115 and the cleaning plate 114 can respectively drive the first abutting block 124 and the second abutting block 134 to perform circular motion together with the rotating shaft 112 while performing circular motion; The rotating shaft 112 rotates clockwise, so that the cleaning plate 114 first contacts the first abutting block 124. Since the first cleaning brush 123 is restricted by the moving column and the first abutting block 124 in 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-circular motion around the center of the bushing tube 200. At this time, the second elastic member 128 is stretched along the trajectory of the first mounting ring 121, and the initial position of the second elastic member 128 is normal. The first cleaning brush 123 rotatably connected to the first abutting block 124 acts on the outer wall of the bushing tube 200 and moves with the movement of the first abutting block 124, so that the first cleaning brush 123 cleans the half of the outer wall of the bottom of the bushing tube 200 in the positive direction. When the cleaning plate 114 pushes the first abutting block 124 to reach the disengagement position of the first limiting track 125, the disengagement portion is set to an arc shape that gradually deviates from the arc of the first limiting track 125, so that the first limiting column 127 on the first abutting block 124 gradually moves away from the cleaning block when moving to the disengagement portion until the cleaning block can rotate the first abutting block 124 through the guide sliding surface 139 during the continuous movement, so that the cleaning block releases the pushing effect on the first abutting block 124 and can continue to perform a circular motion with the center of the bushing tube 200; After the first abutting block 124 is separated from the cleaning block, the second elastic member 128 is stretched to the maximum state, and the second elastic member 128, under the action of the elastic restoring force, makes the first limiting column 127 on the first abutting block 124 gradually slide from the disengaging portion to the first limiting track 125, and in this recovery process, the first cleaning brush 123 is reversely cleaned to the half of the outer wall of the bottom of the bushing tube 200, thereby achieving one positive cleaning and one reverse cleaning of the half of the outer wall of the bushing tube 200 at a time, and such repeated cleaning is a cycle, so that the first cleaning brush 123 has a better cleaning effect on the bushing tube 200, and the use of the second elastic member 128 has another advantage that during the rebound process of the first abutting block 124, the first cleaning brush 123 will have a buffering effect and when it contacts the bushing tube 200, the first cleaning brush 123 will vibrate, so that impurities on the first cleaning brush 123 can be shaken off, reducing the impurities attached to the first cleaning brush 123 during long-term use; 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.

[0025] Embodiment 2 Reference Figure 1-Figure 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. 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.

[0026] Reference Figure 14-17The 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; 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; 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. 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, so that the first rack 213 can no longer move, while the second cleaning brush 133 continues to move, causing the toggle block 221 to rotate, thereby avoiding contact with the toggle block 221. At this time, movement in two directions occurs. First, under the action of the rebound force 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 opposite direction. The rotating gear 216 rotates clockwise, driving the second rack 217 to move in a direction away from the electromagnetic winding, thereby wiping the electromagnetic winding again, realizing repeated wiping of the electromagnetic winding. The second cleaning brush 133 continues to move until it moves to the electrode position and contacts the electrode, thereby cleaning the end of the electrode; During the flow rate detection process, the first power device can make the rotating shaft 112 perform circular motion all the time. The rotation of the rotating shaft 112 makes the cleaning plate 114 and the holding plate 115 perform circular motion all the time. As long as the cleaning plate 114 and the holding plate 115 keep moving in a circular motion, the outer wall and inner diameter of the bushing tube 200 as well as the electromagnetic winding and the electrode can be kept cleaned, thereby achieving a comprehensive cleaning of the IO-Link electromagnetic flowmeter body 100, and ensuring the accuracy of the liquid flow rate detection during use; It should be noted that the electrodes cannot be cleaned meticulously because they are extremely delicate and should not be cleaned thoroughly during use, as this can easily cause damage.

[0027] How this application works: Filtering and cleaning: the rotating shaft 112 generates power driven by the first power device, allowing the liquid to pass from the filter plate 111 into the liner tube 200 for speed measurement, while the cleaning plate 114 and the holding plate 115 rotate to clean the impurities on the filter plate 111; 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. The electromagnetic winding is cleaned. The first abutment block 124 and the second abutment block 134 are pushed by the cleaning plate 114 and the holding plate 115 respectively and move successively, and the first cleaning brush 123 and the second cleaning brush 133 are moved respectively, so that the first rack 213 is driven to move toward the bottom of the electromagnetic winding under the drive of the toggle block 221, and the second rack 217 which is also meshed with the rotating gear 216 is also moved toward the two sides of the electromagnetic winding for cleaning; Electrode cleaning: After the electromagnetic winding is cleaned, the toggle block 221 and the wiping block 222 act on the end of the electrode to achieve cleaning.
