Description

Technical Field

[0001] This utility model relates to the field of electromagnetic flowmeter technology, and in particular to an integrated flow velocity and liquid level open channel flowmeter. Background Technology

[0002] Electromagnetic flow sensors consist of components such as a measuring tube, magnetic circuit system, electrodes, and interference adjuster. They are used to measure the instantaneous flow rate and volumetric flow rate of conductive liquids and slurries. Structurally, electromagnetic flow sensors can be divided into two types: split type and integrated type. Existing electromagnetic flow meter sensors all have an integrated liquid level and flow velocity structure for full-channel-width open channels.

[0003] Existing patent: CN202123342948.X A liquid level and flow rate integrated full-channel wide open channel electromagnetic flow meter sensor. By cooperating with components such as locking components and supporting arc plates, the limiting baffle can be locked onto the left and right sides of the outer surface of the electromagnetic flow meter sensor. This locks and limits the electromagnetic flow meter sensor, provides stable support, and prevents the whole body from shaking when the liquid flow rate is too high, thus affecting the metering and sensing effect.

Flange connections require multiple bolts, and the flange on the pipeline is connected to the flange on the flow meter by tightening the nuts. This installation method is cumbersome to disassemble and difficult to install, and the installation and disassembly efficiency is low, which reduces the efficiency of flow meter installation and disassembly and reduces the user experience of the flow meter in practical use.

[0044] Please see Figure 1-5 The present invention provides a technical solution: including a flow meter body 1, an inlet pipe and an outlet pipe provided on the flow meter body 1, the inlet pipe and the outlet pipe communicating with the interior of the flow meter body 1, and fixing blocks 2 fixedly sleeved at both opposite ends of the inlet pipe and the outlet pipe.

[0045] Among them, the outer surfaces of the two opposite sides of the fixing blocks 2 are provided with mounting grooves 12;

[0046] The fixed block 2 is equipped with an installation mechanism, which includes a support block 3, a sliding groove 4, a positioning slider 5, a connecting block 6, a rotating hole 7, a bidirectional threaded rod 8, a handle 9, a connecting pipe 10, a support groove 11, an internal groove 13, a fixed rotating rod 14, a first bevel gear 15, and a second bevel gear 16.

[0047] Furthermore, the support block 3 is fixedly sleeved on the corresponding fixing block 2;

[0048] The rotating hole 7 is opened on the left side surface of the corresponding support block 3, and the rotating hole 7 extends out of the right side surface of the corresponding support block 3.

[0049] The bidirectional threaded rod 8 is rotatably mounted on the corresponding rotating hole 7 via a bearing.

[0050] Furthermore, the two threads on the bidirectional threaded rod 8 are located outside the support block 3;

[0051] Among them, the two connecting blocks 6 are threadedly sleeved on the outer surface of the corresponding bidirectional threaded rod 8, and the two connecting blocks 6 are located on the two opposite threads of the corresponding bidirectional threaded rod 8.

[0052] The two mounting slots 12 are connected to the interior of the corresponding inlet and outlet pipes.

[0053] Furthermore, a flange is fixedly connected to the connecting pipe 10, and the flange on the connecting pipe 10 is slidably connected to the mounting groove 12;

[0054] Two support grooves 11 are formed on the outer surface of the corresponding fixing block 2, and the support grooves 11 are connected to the interior of the corresponding mounting grooves 12.

[0055] Among them, two sliding grooves 4 are opened on the outer surfaces of the corresponding support blocks 3 on the left and right sides;

[0056] Among them, the two sliding grooves 4 are connected to the two corresponding support grooves 11.

[0057] Furthermore, the two positioning sliders 5 are fixedly connected to the adjacent outer surfaces of the two corresponding connecting blocks 6;

[0058] Among them, the outer surfaces of the two adjacent positioning sliders 5 on the left and right sides are inclined surfaces;

[0059] The positioning slider 5 is slidably connected to the corresponding sliding groove 4 and support groove 11;

[0060] The inclined surface of the positioning slider 5 is slidably connected to the flange on the connecting pipe 10.

[0061] Furthermore, the fixed rotating rod 14 is rotatably connected to the upper surface of the corresponding support block 3;

[0062] The internal groove 13 is formed within the corresponding support block 3;

[0063] The lower end of the fixed rotating rod 14 rotates and penetrates into the corresponding internal groove 13.

[0064] Furthermore, the second bevel gear 16 is fixedly sleeved on the outer surface of the corresponding bidirectional threaded rod 8;

[0065] The first bevel gear 15 is fixedly connected to the upper surface of the fixed rotating rod 14, and the second bevel gear 16 and the first bevel gear 15 are both located in the internal groove 13, with the second bevel gear 16 meshing with the first bevel gear 15.

[0068] In use, slide the flange on the connecting pipe 10 into the corresponding mounting groove 12, then turn the handle 9. The rotation of the handle 9 synchronously drives the fixed rotating rod 14 and the first bevel gear 15 to rotate, which in turn drives the second bevel gear 16 to rotate, which in turn drives the bidirectional threaded rod 8 to rotate. The rotation of the bidirectional threaded rod 8 causes the two corresponding connecting blocks 6 to move closer or further apart. When the two connecting blocks 6 move closer together, they synchronously drive the two positioning sliders 5 to slide into the mounting groove 11, causing the inclined surface of the positioning sliders 5 to move away from the flange on the connecting pipe 10 and away from the flowmeter body 1. The outer surface of the flange on the connecting pipe 10 is in contact with the flange, and the inclined surface of the positioning slider 5 presses against the outer surface of the flange on the connecting pipe 10 away from the flow meter body 1. This causes the flange on the connecting pipe 10 to press against the inner wall of the mounting groove 12, making the flange on the connecting pipe 10 fit more tightly against the inner wall of the mounting groove 12. This allows for the installation and connection between the connecting pipe 10 and the inlet or outlet pipe, making installation convenient and quick. Installation and disassembly can be completed simply by turning the handle 9. This improves installation efficiency, reduces labor, and simplifies operation, thereby increasing the efficiency of flow meter installation and enhancing its practicality.

[0071] The bidirectional threaded rod 8 drives the two connecting blocks 6 to move in relative or opposite directions;

[0072] Positioning slider 5: In the initial state, the inclined surface of the positioning slider 5 is located in the support groove 11. The inclined surface of the positioning slider 5 is close to the flange on the connecting pipe 10. As the positioning slider 5 extends into the installation groove 12, the positioning slider 5 exerts a squeezing force on the connecting pipe 10, thereby ensuring that the connecting pipe 10 and the installation groove 12 are closer together and fixing the connecting pipe 10 in the installation groove 12, thereby realizing the installation connection between the connecting pipe 10 and the inlet pipe or outlet pipe.

[0073] Internal groove 13: provides rotational space for the first bevel gear 15 and the second bevel gear 16;

[0074] Fixed block 2: The structures on the two fixed blocks 2 are exactly the same and are set in a mirror image.
