Description

Technical Field

[0001] The utility model relates to the field of electromagnetic flowmeters, in particular to a portable electromagnetic flowmeter. Background Art

[0002] Electromagnetic flowmeter is a new type of flow measurement instrument that has developed rapidly 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 electromotive force generated when the conductive fluid passes through an external magnetic field. The structure of the electromagnetic flowmeter is mainly composed of a magnetic circuit system, a measuring conduit, electrodes, a casing, a lining and a converter.

[0003] After searching, Chinese patent document announcement number: CN219977472U discloses a portable electromagnetic flowmeter, especially a portable electromagnetic flowmeter. When the viewing angle of the electromagnetic flowmeter needs to be adjusted according to the existing needs, different through holes need to be replaced for installation, and the number of through holes is limited, which leads to the problem that the viewing angle of the electromagnetic flowmeter is limited during installation. The following scheme is now proposed, which includes a flowmeter body, both ends of the flowmeter body are fixedly connected with connecting pipes, and both ends of the connecting pipe are provided with fixing components for fixing the flowmeter body. When the product in the utility model is installed, the angle of the flowmeter body can be adjusted after the connecting ring is connected to the pipeline, and then it is locked and fixed, thereby improving the flexibility of product use. At the same time, through the coordinated use of the rubber protrusion and the extension protrusion, after the connecting ring is locked, the extension protrusion and the rubber protrusion can be stuck to each other to prevent the flowmeter body from rotating, thereby improving the stability of the flowmeter body.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 3The utility model provides an embodiment: a portable electromagnetic flowmeter, including a shell 1, the top of the shell 1 is fixedly connected with an external display instrument 2, the external display instrument 2 is usually designed to be movable or installable in a convenient position for operation, so that the user can easily view key data without directly approaching the detected equipment or system. The top of the external display instrument 2 is fixedly connected with a fixing plate 3, the rear of the fixing plate 3 is fixedly connected with a motor 4, the driving end of the motor 4 is fixedly connected with a rotating shaft 5, the rotating shaft 5 as a transmission element in the mechanical system, can effectively transmit power and torque, so that the mechanical equipment can operate normally, the outer side of the rotating shaft 5 is fixedly connected with a rotating plate 6, the rotating plate usually has low energy consumption, and high efficiency can be achieved by optimizing the design and operating parameters. Energy conversion and low-energy operation The right rear part of the rotating plate 1 6 is rotatably connected to the rotating plate 2 7, and the right rear part of the rotating plate 2 7 is fixedly connected to the gear 8. The gear 8 transmission usually has a high mechanical efficiency, especially under the condition of correct lubrication and appropriate design, which means that most of the input power can be transmitted to the output end in an effective way, reducing energy loss. The fixed plate 3 is provided with a sliding groove 21 inside, and the inner wall of the sliding groove 21 is slidably connected to the left and right sides with T-shaped sliders 9. The outside of the two T-shaped sliders 9 is fixedly connected to one of the racks 10, and the front side of the fixed plate 3 is fixedly connected to another rack 10. The rack 10 transmission usually has a high transmission efficiency because they transmit power directly to the teeth on the rack 10 without the need for additional transmission elements. This direct transmission minimizes energy loss and improves the efficiency of the entire system. The top of one of the racks 10 is fixedly connected to a connecting frame 11, and the front inner wall of the connecting frame 11 is fixedly connected to a brush 12. The inside of the housing 1 is fixedly connected to a disassembly component.

One of the main characteristics of the multiple springs 18 is their elasticity, that is, they can return to their original shape after being subjected to force. This characteristic enables the spring 18 to generate a reaction force when subjected to compression, tension or torsion, and return to its original shape after the force disappears, which is very useful for various applications. The near sides of the springs 18 are respectively fixedly connected to the far sides of the multiple boxes 16.

[0030] Working principle: starting the motor 4 causes the rotating shaft 5 to drive the rotating plate 1 6 to rotate, the rotating plate 1 6 rotates and then drives the rotating plate 2 7, the rotating plate 2 7 drives the gear 8 to move, the gear 8 drives the rack 10 to move left and right, the rack 10 moves and then drives the connecting frame 11, the connecting frame 11 drives the brush 12, the brush 12 moves left and right to clean the external display instrument 2, thus completing the cleaning work, and then facilitating people to clean the external display instrument, improving the automation of cleaning and eliminating the need for people to clean repeatedly.

[0031] Insert one end of the disassembly assembly with the bolt 15 into the hole groove of the flange 14 and rotate it to make the box 16 contact with the flange 14. When disassembling, rotate the nut 20 clockwise or counterclockwise to make it separate from the flange 14, thereby facilitating the fixation of the flange, realizing the rapid installation and disassembly of the flow meter, and improving people's rapid disassembly and repair when the machine breaks down.
