[0020] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the present invention may be practiced without one or more of these details. In other instances, well-known features have not been described in order to avoid obscuring the invention.

[0021] Unless otherwise defined, the directions such as up, down, left, right, front, back, inside and outside involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in the present invention, which are hereby explained together.

[0022] This embodiment discloses an electromagnetic flowmeter with a protection structure as shown in Figures 1 to 5 which includes an electromagnetic flow valve body 1, a connecting pipe 3 installed on its top surface, and an electromagnetic flow converter 2 installed at the top end of the connecting pipe 3. A first protection and purification cylinder 7 and a second protection and purification cylinder 8 are respectively installed at both ends of the electromagnetic flow valve body 1. The bottom surfaces of the first protection and purification cylinder 7 and the second protection and purification cylinder 8 are fixedly connected with a U-shaped buffer support frame 9. Arc-shaped connecting surfaces adapted to the outer walls of the first protection and purification cylinder 7 and the second protection and purification cylinder 8 are provided at the top of both ends of the U-shaped buffer support frame 9. Specifically, a multi-stage filtering component is arranged in the inner cavity of the first protection and purification cylinder 7. The multi-stage filtering component includes a first filter element 15 and a second filter element 16 symmetrically and fixedly installed in the inner cavity of the first protection and purification cylinder 7. The mesh size of the first filter element 15 is larger than that of the second filter element 16. A cross support frame 13 is fixedly installed on the inner wall of the first protection and purification cylinder 7 on the side of the first filter element 15 facing away from the second filter element 16. An anti-blocking stirring impeller 14 is rotatably installed on the inner wall of the cross support frame 13. The anti-blocking stirring impeller 14 faces the first filter element 15 to stir and clean the impurities accumulated on the surface of the first filter element 15.

[0023] Specifically, the first filter element 15 is arranged near the fluid inlet and has a larger mesh size for initially intercepting large particle impurities. The second filter element 16 has a finer mesh size and follows closely for further filtering tiny impurities. The two filter elements are connected and fixed by a first connecting rod 17 for easy overall disassembly, cleaning or replacement. The setting of the cross support frame 13 and the anti-blocking stirring impeller 14 ensures that the impurities flowing through the surface of the first filter element 15 can be effectively stirred and shed, reducing the risk of blockage.

[0024] Specifically, a purification component is arranged in the inner cavity of the second protective purification cylinder 8. The purification component includes an activated carbon filter adsorption net 18 and a fixed sleeve 19 arranged at one end facing away from the electromagnetic flow valve body 1. The fixed sleeve 19 is filled with sand and gravel 20 for purifying water. The activated carbon filter adsorption net 18 uses its strong adsorption ability to remove organic substances, pigments, etc. in the water, while the sand and gravel 20 filled inside the fixed sleeve 19 further filters out particulate impurities to improve water quality. The second connecting rod 21 connects the activated carbon filter adsorption net and the fixed sleeve, facilitating maintenance and replacement.

[0025] Specifically, shock-absorbing buffer components are symmetrically installed on the inner bottom wall of the U-shaped buffer support frame 9. The top buffer ends of the shock-absorbing buffer components are elastically abutted against the outer wall of the electromagnetic flow valve body 1. The shock-absorbing buffer components include two air spring shock absorbers 11 installed on the inner bottom wall of the U-shaped buffer support frame 9. The top ends of the air spring shock absorbers 11 are elastically abutted against the bottom outer wall of the electromagnetic flow valve body 1 to form a buffer layer, effectively absorbing external vibrations and protecting internal sensitive components.

[0026] Specifically, a through-connection pipe 3 is connected between the top surfaces of the first protective purification cylinder 7 and the second protective purification cylinder 8, and an inverted U-shaped support and hoisting plate 4 is provided. A positioning vertical plate member 25 is fixed on one side of the top surface of the U-shaped support and hoisting plate 4. A connection pipe head 5 is connected to the outer wall of the tail end of the electromagnetic flow converter 2. A plurality of pipe-passing holes 6 for combing the connection pipe are symmetrically formed inside the positioning vertical plate member 25, facilitating the orderly arrangement and fixation of the connection pipe 3.

[0027] Specifically, a support block 22 is rotatably connected to the bottom surface of the U-shaped buffer support frame 9. A support column 10 is installed on the bottom surface of the support block 22. A servo motor 23 is embedded in the top surface of the support block 22. The output shaft of the servo motor 23 is connected to the bottom surface of the U-shaped buffer support frame 9. A plurality of positioning steel balls 24 are rollingly embedded on both sides of the top surface of the support block 22. The positioning steel balls 24 are in rolling friction contact with the bottom surface of the U-shaped buffer support frame 9. The support column 10 at the bottom of the support block 22 ensures the stable standing of the entire device, while the built-in servo motor 23 can adjust the angle of the support block as needed to adapt to different installation environments. The application of the positioning steel balls 24 reduces friction, making the movement of the support structure smoother.

[0028] Specifically, the first filter element 15 and the second filter element 16 are connected by a first connecting rod 17, and the activated carbon filter adsorption net 18 and the fixed sleeve 19 are connected by a second connecting rod 21.

[0029] Working principle For the electromagnetic flowmeter with a protective structure, when water flows through the pipeline and enters the electromagnetic flowmeter, it first enters the first protective purification cylinder 7, where the multi-stage filtering component starts to work. The first filter element 15 intercepts larger solid impurities first, and then the finer second filter element 16 further filters. The anti-blocking stirring impeller 14 rotates driven by the cross support frame 13, which can effectively prevent the accumulation of impurities on the surface of the first filter element 15 and keep the flow smooth. The fluid continues to flow to the electromagnetic flow valve body 1 through the purified first protective purification cylinder. During this process, the air spring shock absorber 11 in the U-shaped buffer support frame 9 can absorb the vibration from the pipeline, protect the electromagnetic flow valve body from mechanical vibration, and ensure the measurement accuracy. At the same time, the support block 22 driven by the servo motor 23 can adjust the support angle as needed to enhance adaptability; When the purified water flow passes through the electromagnetic flow valve body, an induced electromotive force is generated inside the flowmeter because the conductive medium cuts the magnetic force lines. The electromagnetic flow converter 2 detects this electromotive force and accurately calculates the flow rate of the fluid by combining the pre-set flow velocity - electromotive force relationship. Then the fluid enters the second protective purification cylinder 8, where the activated carbon filter adsorption net 18 further adsorbs organic substances, pigments, etc. in the water, and the sand and gravel in the fixed sleeve 19 further filter fine impurities. Finally, the purified water flow is discharged through the system.
