[0001] The utility model relates to the technical field of electromagnetic flowmeters, and specifically relates to an electromagnetic flowmeter with a protection structure. Background Technique

[0002] An electromagnetic flowmeter is an instrument used to measure the flow rate of conductive liquids. When a conductive liquid passes through a magnetic field, an induced electromotive force will be generated in the liquid, thereby realizing the measurement and control of the flow rate, and at the same time, the detection results are intuitively displayed through the top display area.

[0003] When the existing electromagnetic flowmeter measures the flow rate of the medium in the pipeline, it needs to be detected through a connector. When not in use, the connector is exposed to the outside, which is likely to cause dust to enter the interior, and then lead to unstable signal of the induced electromotive force, which may reduce the measurement accuracy of the electromagnetic flowmeter. Therefore, an electromagnetic flowmeter with a protection structure is proposed. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0024] Next, the embodiments of the present utility model will be described according to its overall structure.

[0025] An electromagnetic flowmeter with a protection structure, as Figures 1-5 shown, includes a main body 100 of the electromagnetic flowmeter. A sensor 110 is installed at the top of the main body 100 of the electromagnetic flowmeter. A connector 120 is provided on one side of the sensor 110. A protection component 200 is provided on the surface of the connector 120. A cleaning component 300 is provided at the front end of the sensor 110. The protection component 200 includes a protective sleeve 210 sleeved on the surface of the connector 120. A connecting plate 220 is welded to the side of the protective sleeve 210 away from the connector 120. A cross plate 230 is fixedly connected to one side of the connecting plate 220. A round rod 240 is slidably connected to the side of the cross plate 230 away from the connecting plate 220. A bearing 250 is slidably connected to the surface of the round rod 240. The bearing 250 is fixedly connected to the cross plate 230, and a connecting spring 260 is fixed to the side of the bearing 250 away from the cross plate 230.

[0026] When it is necessary to connect with the connector 120, the staff member pulls the cross plate 230 to move the cross plate 230 on the round rod 240, and drives the bearing 250 to stretch the connecting spring 260. The connecting plate 220 is driven to move synchronously by the movement of the cross plate 230, and the connecting plate 220 drives the protective sleeve 210 to slide out from the inside of the connector 120. The cross plate 230 is rotated to drive the connecting plate 220 and the protective sleeve 210 to rotate synchronously. Subsequently, the staff member holds a tool to connect with the connector 120 for detection. After the detection is completed, the protective sleeve 210 is sleeved into the inside of the connector 120 again, which can effectively prevent dust from entering the inside of the connector 120 when it is not in use, avoid the instability of the induced potential signal transmitted by the connector 120 due to the entry of dust, and better improve the measurement accuracy of the electromagnetic flowmeter main body 100, so that it can more accurately reflect the flow information of the fluid.

[0027] Please refer particularly to Figure 2 and Figure 3 , a limiting strip 241 is welded on the surface of the round rod 240, and a round shaft 270 is fixedly connected to the side of the round rod 240 away from the limiting strip 241. The round shaft 270 is rotatably connected to the sensor 110. The side of the connecting spring 260 away from the bearing 250 is fixedly connected to the sensor 110, and a display screen 130 is provided at the front end of the sensor 110.

[0028] By setting the connecting spring 260, the protective sleeve 210 can be prevented from falling off from the connector 120. By setting the bearing 250, the connecting spring 260 can be prevented from rotating when the cross plate 230 rotates.

[0029] Please refer particularly to Figure 1 , Figure 2 and Figure 4 , the cleaning component 300 includes a wiping piece 310 attached to the surface of the display screen 130. Two first wire ropes 320 are fixedly connected to one side of the wiping piece 310. A first guide shaft 330 for changing the extending direction of the first wire rope 320 is provided on the surface of the first wire rope 320. One end of the first wire rope 320 away from the wiping piece 310 is connected to a fixing plate 340. A second wire rope 350 is fixedly connected to the side of the wiping piece 310 away from the first wire rope 320. A second guide shaft 360 for changing the extending direction of the second wire rope 350 is provided on the surface of the second wire rope 350. A return spring 370 is sleeved on the surface of the second wire rope 350. One end of the second wire rope 350 away from the wiping piece 310 is fixedly connected to a sliding plate 380.

[0030] The staff member pulls the fixing plates 340 on both sides, causing the fixing plates 340 to pull the first wire rope 320, which in turn drives the second wiping member 310 to move. The second wiping member 310 is used to clean the dust and moisture on the surface of the display screen 130. While the wiping member 310 is moving, it pulls the second wire rope 350 and the sliding plate 380 to move, causing the sliding plate 380 to compress the return spring 370. After the cleaning is completed, the fixing plates 340 are released, and the wiping member 310 is reset by the force of the return spring 370, facilitating the next cleaning of the display screen 130. By removing the dust and moisture on the display screen 130, the displayed content becomes clearer, making it convenient for the staff to read the data, improving work efficiency, and avoiding the obstruction caused by stains, which may affect the operator's judgment and thus the measurement accuracy.

[0031] Please refer specifically to Figure 2 and Figure 5 , a chute 381 is provided inside the sensor 110, and the sliding plate 380 is slidably connected to the chute 381.

[0032] By providing the chute 381, the sliding plate 380 can compress the return spring 370 when sliding inside the sensor 110.

[0033] During use, by pulling the cross plate 230, the protective sleeve 210 slides out from inside the connector 120, and then the cross plate 230 is rotated, causing the cross plate 230 to drive the connecting plate 220 and the protective sleeve 210 to rotate synchronously. Subsequently, the staff holds a tool and connects it to the connector 120 for detection. After the detection is completed, the protective sleeve 210 is put back into the connector 120 again, which can effectively prevent dust from entering the connector 120 when it is not in use, avoiding the instability of the induced potential signal transmitted by the connector 120 due to dust entry, and better improving the measurement accuracy of the electromagnetic flowmeter main body 100, enabling it to more accurately reflect the flow information of the fluid. The staff then pulls the fixing plates 340 on both sides, causing the first wire rope 320 to drive the second wiping member 310 to move and clean the dust and moisture on the surface of the display screen 130. By removing the dust and moisture on the display screen 130, the displayed content becomes clearer, making it convenient for the staff to read the data, improving work efficiency, and avoiding the obstruction caused by stains, which may affect the operator's judgment and thus the measurement accuracy. The parts not involved in this device are the same as or can be implemented using the prior art.
