Description

Technical Field

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

[0002] The electromagnetic flowmeter is an inductive instrument manufactured according to Faraday's law of electromagnetic induction and is used to measure the volume flow rate of conductive media in a pipe. The structure of the electromagnetic flowmeter is mainly composed of a magnetic circuit system, a measuring tube, electrodes, a casing, a lining and a converter. It can be divided into an integrated electromagnetic flowmeter and a split electromagnetic flowmeter. Among them, the split electromagnetic flowmeter is an inductive instrument that measures the volume flow rate of conductive media in a pipe according to Faraday's law of electromagnetic induction. It adopts single-chip embedded technology and can remotely observe the measurement value of the electromagnetic flowmeter through signal wires and display devices.

[0003] However, when the prior art is actually used, during the installation process, the split electromagnetic flowmeter is usually fixedly connected to the measured pipeline through a fixed connecting flange. After the split electromagnetic flowmeter is fixedly connected to the measured pipeline through the fixed connecting flange, it is not convenient to adjust the installation angle of the split electromagnetic flowmeter. When the measured pipeline environment is relatively small and the distance to multiple external pipelines is close, the split electromagnetic flowmeter is easily blocked by the external pipelines, resulting in the split electromagnetic flowmeter occupying a fixed space after installation, resulting in poor flexibility. Utility Model Content

After the split electromagnetic flowmeter is fixedly connected to the measured pipeline through the fixed connecting flange, it is not convenient to adjust the installation angle of the split electromagnetic flowmeter. When the measured pipeline environment is relatively narrow and the distance to multiple external pipelines is close, the split electromagnetic flowmeter is easily blocked by the external pipelines, resulting in the split electromagnetic flowmeter occupying a fixed space after installation, thereby having poor flexibility.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: it includes a split electromagnetic flowmeter body, a rotating connecting flange and a mounting plate, the lower end side wall of the electromagnetic flowmeter body is fixedly connected to a support block, the middle part of the side end of the support block is rotatably connected to a support column, the lower end outer curved surface of the support column is threadedly connected to a support tube, the bottom of the support tube is rotatably connected to a connecting block through a rotating shaft, the upper end surface of the mounting plate is fixedly connected to a support rod, the upper end of the support rod is rotatably connected to a U-shaped support frame, the lower end of the U-shaped support frame is rotatably connected to a screw through a rotating shaft, the outer curved surfaces on both sides of the screw are threadedly connected to L-shaped support arms, the upper end of the U-shaped support frame is provided with limited sliding grooves on both side walls, and the inner side of the upper end of the L-shaped support arm is fixedly connected to an arc clamping plate.

[0007] Preferably, an external thread is provided on the outer curved surface of the support column, the mounting plate is rotatably connected to the lower end of the connecting block, and a first fixing nut is threadedly connected to the outer curved surface of the upper end of the support column.

[0008] Preferably, mounting holes are formed through the four corners of the upper end surface of the mounting plate, and there are four mounting holes, which are symmetrically distributed at the four corners of the upper end surface of the mounting plate.

[0009] Preferably, there are two support rods, which are symmetrically distributed on both sides of the upper end surface of the mounting plate, and the threads of the outer curved surfaces on both sides of the screw rod are in opposite directions, and a knob is fixedly connected to the top end of the screw rod.

[0011] Preferably, the outer curved surface of the side end of the screw is threadedly connected with a second fixing nut, and the inner curved surface of the arc-shaped clamping plate fits on the outer curved surfaces on both sides of the lower end of the electromagnetic flowmeter body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the support tube of the utility model rotates, the support column will be driven to move downward due to the force of the threaded connection with the outer curved surface of the lower end of the support column. When the support column moves downward, the upper end of the electromagnetic flowmeter body can be driven to swing downward for adjustment. When the upper end of the electromagnetic flowmeter body is swung downward for adjustment, the support column can be locked and fixed by rotating the first fixing nut, thereby realizing the effect that the electromagnetic flowmeter body can be swung downward for adjustment and locked and fixed;

[0014] 2. The utility model also drives the arc-shaped clamping plate to move inward when the L-shaped support arm moves inward synchronously, thereby clamping the outer curved surfaces on both sides of the lower end of the electromagnetic flowmeter body, so that the outer curved surfaces on both sides of the lower end of the electromagnetic flowmeter body can be swing-supported in turn through the support rod, thereby achieving the electromagnetic flowmeter body being able to swing downward for adjustment while the outer curved surfaces on both sides of the lower end of the electromagnetic flowmeter body being swing-supported, thereby improving the stability of the electromagnetic flowmeter body's downward swing adjustment.
