Description

Technical Field

[0001] The present application relates to the technical field of electromagnetic flowmeters, and in particular to an electromagnetic flowmeter that is easy to read. Background Art

[0002] Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow rate of conductive fluids based on the electromotive force induced when the conductive fluid passes through an external magnetic field. Electromagnetic flowmeters are usually equipped with a display screen to display the flow data in the pipeline in real time. However, in actual use, it is often difficult to adjust the angle of the display screen, so that after the electromagnetic flowmeter is connected to the pipeline, the observer can only walk to the opposite side of the display screen to read the reading. This is inconvenient when the pipeline layout is more complicated. In addition, the display screen is usually in direct contact with the air, and its surface will be contaminated by dust and rain, causing the display screen to become dirty and blurred, which is difficult to meet the use needs in production and life.

[0032] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] The present application embodiment discloses an electromagnetic flowmeter that is easy to read. Figure 1 The electromagnetic flowmeter includes an electromagnetic flow pipe 1, a signal processor 2 and a display screen 3. The display screen 3 is equipped with a transparent cover 6. The inner wall of the transparent cover 6 is fixedly provided with an internal thread. The outer wall of the signal processor 2 close to the display screen 3 is fixedly provided with an external thread. The transparent cover 6 is threadedly connected to the signal processor 2; a cleaning mechanism 5 is fixedly provided at one end of the signal processor 2 for cleaning the transparent cover 6 outside the display screen 3. A rotating component 4 is vertically fixed on the outer wall of the signal processor 2 for adjusting the direction of the display screen 3. The end of the rotating component 4 away from the signal processor 2 is fixedly provided on the outer wall of the electromagnetic flow pipe 1, and the rotating component 4 is connected to the electromagnetic flow pipe 1.

[0034] Reference Figure 1-3 The rotating assembly 4 includes a connecting cylinder 41 and a horizontal rotating cylinder 42. The connecting cylinder is vertically fixed to the outer wall of the electromagnetic flow pipe 1 and is connected to the electromagnetic flow pipe 1. The horizontal rotating cylinder 42 is vertically fixed to the outer wall of the signal processor 2. The outer wall of the signal processor 2 is provided with a plurality of data line through holes (not shown in the figure), and the data line through holes are connected to the horizontal rotating cylinder 42; the inner wall of the horizontal rotating cylinder 42 is provided with a limiting groove 421, and the outer wall of the connecting cylinder 41 is fixedly provided with a limiting ring 411. The horizontal rotating cylinder 42 is sleeved on the outer wall of the connecting cylinder 41, and the limiting ring 411 is adapted to fit with the limiting groove 421. The limiting ring 411 is rotationally connected with the limiting groove 421 through an interference fit. When the direction of the display screen 3 needs to be adjusted for reading, the horizontal rotating cylinder 42 is manually rotated. After the horizontal rotating cylinder 42 is rotated to a certain position by manpower, the friction force at the connection between the limiting ring 411 and the limiting groove 421 makes the signal processor 2 hover at the angle required by the observer, so as to achieve the purpose of adjusting the direction of the display screen 3.

[0035] Reference Figure 4-6The cleaning mechanism 5 includes a transmission component 51 and a cleaning component 52. The transmission component 51 includes a mounting seat 511, a first rotating shaft 512 and a second rotating shaft 514. The mounting seat 511 is fixedly arranged at one end of the signal processor 2 away from the display screen 3. The first rotating shaft 512 is arranged inside the mounting seat 511 and is rotatably connected to the side wall of the mounting seat 511. The second rotating shaft 514 is arranged parallel to the first rotating shaft 512. One end of the second rotating shaft 514 is arranged inside the mounting seat 511 and is rotatably connected to the side wall of the mounting seat 511, and the other end passes through the mounting seat 511 and is fixedly connected to the cleaning component 52. The outer wall of the first rotating shaft 512 is fixedly sleeved with a first gear 513, and the outer wall of the second rotating shaft 514 is fixedly sleeved with a second gear 515. The first gear 513 and the second gear 515 are meshed. A gear 513 and a second gear 515 are both arranged inside the mounting base 511. An opening is provided on the side wall of the mounting base 511. A handle 5131 is fixedly provided on the side wall of the first gear 513. The handle 5131 extends out of the mounting base 511 through the opening. When it is necessary to clean the transparent cover 6, the position of the handle 5131 is manually adjusted to make the handle 5131 move back and forth along the range of the opening, so that the first gear 513 rotates back and forth within a certain angle range. The first gear 513 drives the second gear 515 to rotate synchronously, and the second gear 515 drives the second rotating shaft 514 to rotate. The cleaning component 52 is fixed to the second rotating shaft 514. When the second rotating shaft 514 rotates, the cleaning component 52 rotates relative to the transparent cover 6 to achieve the purpose of making the cleaning component 52 rub the surface of the transparent cover 6 to clean it.

[0036] The cleaning assembly 52 includes a brush rod 521 and a brush head 523. The brush rod 521 is fixed to one end of the second rotating shaft 514 away from the mounting seat 511. The brush rod 521 is perpendicular to the second rotating shaft 514. A first magnetic sheet 522 is fixed to the side of the brush rod 521 facing the display screen 3. A second magnetic sheet 524 is fixed to the side of the brush head 523 facing the brush rod 521. The brush rod 521 and the brush head 523 are detachably connected by magnetic force. The side of the brush head 523 facing away from the brush rod 521 abuts against the transparent cover 6. When the second rotating shaft 514 rotates, the brush rod 521 is driven to rotate simultaneously. The axis rotates, and the brush head 523 is in close contact with the surface of the transparent cover 6 and rotates and wipes synchronously. After wiping, if it is necessary to read the reading of the display screen 3, the brush rod 521 is rotated and away from the display screen 3, so as to directly read the reading of the display screen 3. When the brush head 523 becomes dirty and needs to be replaced, the first magnetic sheet 522 is separated from the second magnetic sheet 524, so that the brush head 523 is quickly removed, and the second magnetic sheet 524 on the new brush head 523 is fixed to the first magnetic sheet 522 again by magnetic force, so that the whole process of replacing the brush head 523 is faster and more efficient.

[0037] The implementation principle of an electromagnetic flowmeter that is easy to read in an embodiment of the present application is as follows: when it is necessary to adjust the direction of the display screen 3 for reading, the horizontal rotating cylinder 42 is manually rotated. Since the limiting ring 411 and the limiting groove 421 are rotatably connected by interference fit, when the horizontal rotating cylinder 42 is rotated to a certain position by manpower, the friction force at the connection between the limiting ring 411 and the limiting groove 421 causes the signal processor 2 to hover at the angle required by the observer, so as to achieve the purpose of adjusting the direction of the display screen 3; when it is necessary to clean the transparent cover 6, the position of the handle 5131 is manually adjusted to make the handle 5131 move back and forth along the range of the opening, so that the first gear 513 rotates back and forth within a certain angle range, and the first gear 513 rotates back and forth within a certain angle range. 3 drives the second gear 515 to rotate synchronously, and the second gear 515 drives the second rotating shaft 514 to rotate. The brush rod 521 is fixed to the second rotating shaft 514. When the second rotating shaft 514 rotates, it will drive the brush rod 521 to rotate coaxially. The brush head 523 is close to the surface of the transparent cover 6 and rotates and wipes synchronously. After wiping, if it is necessary to read the reading of the display screen 3, the brush rod 521 is rotated and away from the display screen 3, so as to directly read the reading of the display screen 3. When the brush head 523 becomes dirty and needs to be replaced, the first magnetic sheet 522 is separated from the second magnetic sheet 524, so that the brush head 523 is quickly removed, and the second magnetic sheet 524 on the new brush head 523 is fixed to each other again by magnetic force.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any feature disclosed in this specification (including the abstract and drawings), unless otherwise stated, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
