Description

A wiring structure for a Coriolis mass flow meter Technical Field

[0001] This utility model belongs to the field of mass flow meter technology, specifically a wiring structure for a Coriolis mass flow meter. Background Technology

[0002] A Coriolis mass flow meter is an instrument that directly measures the mass flow rate of a fluid. Its working principle is based on the Coriolis effect: when a fluid flows in a vibrating pipe, a Coriolis force proportional to the mass flow rate is generated, causing a difference in the phase of the pipe vibration. By detecting this phase difference, the mass flow rate of the fluid can be calculated.

[0003] When wiring the coils of a Coriolis mass flow meter, welding or screws are generally used. Welding makes it difficult to disassemble and replace the coil, while screws can easily damage the wire insulation if the screws are tightened too much, hindering subsequent work. Both of these connection methods have shortcomings. Therefore, a wiring structure for Coriolis mass flow meters is needed to solve these problems. Summary of the Invention

[0004] To overcome the above-mentioned defects, this utility model provides a wiring structure for a Coriolis mass flow meter, which solves the problems of difficulty in disassembling and replacing the coil on the Coriolis mass flow meter, and the fact that if personnel tighten the screws with slightly excessive force, the wires on the coil may be damaged, which would be inconvenient for subsequent work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wiring structure for a Coriolis mass flow meter, including a base, a flow meter body installed on the top of the base, three cylinders fixedly connected to one side of the flow meter body, a fixing plate fixedly connected inside the cylinder, a connecting wire fixedly connected to one side of the fixing plate, a sleeve fixedly connected to the other side of the fixing plate, and a box provided inside the cylinder, the number of boxes being three, with wire one, wire two and wire three fixedly connected to one side of each of the three boxes, and a coil assembly fixedly connected to one end of each of wire one, wire two and wire three;

[0006] A diverter is installed on the base, and a double-row detection tube is installed at the bottom of the diverter. The coil assembly is installed on the double-row detection tube. Two limiting rods are slidably connected to the box body. A hemisphere is fixedly connected to one end of the limiting rod, and a circular plate is fixedly connected to the other end of the limiting rod. There are two circular plates, and a telescopic rod is fixedly connected between the two circular plates. A spring is sleeved on the telescopic rod. Two limiting holes are opened on the cylinder body, and a connecting post is provided inside the sleeve.

[0007] As a further embodiment of this utility model: the connecting wire is electrically connected to the flow meter body, and the two ends of the spring are respectively fixedly connected to two circular plates.

[0008] As a further embodiment of this utility model: one end of the connecting column is designed with an arc surface, and the connecting column is fixed to the box body.

[0009] As a further embodiment of this utility model: four sliding grooves are provided inside the box body, and sliders are slidably connected inside the sliding grooves.

[0010] As a further embodiment of this utility model: the number of sliders is four, and the circular plate is fixed to two sliders.

[0011] As a further embodiment of this utility model: the limiting rod passes through the box body, and the telescopic rod is located inside the box body.

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

[0013] 1. This Coriolis mass flow meter uses a wiring structure, which includes a connecting post, sleeve, spring, hemisphere, limit rod, and limit hole. When the housing needs to be disassembled, squeezing the two hemispheres brings the two limit rods closer together. At this time, the arc surface of the hemispheres will contact the limit hole. Pulling the housing at this point, the hemispheres are squeezed closer together until the limit rods are completely disengaged from the limit hole, allowing the housing to be pulled out and the disassembly work completed. When the housing needs to be installed, placing the housing inside the cylinder and pushing it, when the arc surface of the hemispheres contacts the inner wall of the cylinder, the cylinder will squeeze the hemispheres, causing the two limit rods to come closer together. The limiting rods and the circular plate approach each other, thus compressing the spring. When the hemisphere moves to the limiting hole, the hemisphere loses the squeezing support of the cylinder, causing the spring to reset and push the two limiting rods away from each other, so that the limiting rods are inserted into the limiting hole. At the same time, the connecting post is inserted into the sleeve, thus completing the installation of the box. This structure adopts a modular wire connection method, which makes it simple and quick to install and remove the wires on the coil, thus facilitating the replacement of the coil. Moreover, it abandons the traditional method of connecting with screws, preventing the wires from being damaged by excessive force.

[0014] 2. This Coriolis mass flow meter uses a wiring structure. Through the inclusion of springs, connecting posts, sleeves, limiting rods, and limiting holes, when the housing needs to be installed, the housing is placed inside the cylinder and pushed. When the arc surface of the hemisphere contacts the inner wall of the cylinder, the cylinder will compress the hemisphere, causing the two limiting rods and the circular plate to move closer together, thus compressing the spring. When the hemisphere moves to the limiting hole, it loses the compression support of the cylinder, causing the spring to reset and push the two limiting rods away from each other, allowing the limiting rods to insert into the limiting hole. Simultaneously, the connecting post is inserted into the sleeve, completing the housing installation. When the housing is in the installed state, the flow meter body controls the coil assembly through connecting wires, a fixing plate, connecting posts, sleeves, the housing, and wiring. This structure, by fixing the housing and inserting the connecting post into the sleeve, facilitates the electrical connection between the fixing plate and the housing, thus ensuring the normal operation of the coil assembly.

Detailed Implementation

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] As shown in Figures 1-5, this utility model provides a technical solution: a wiring structure for a Coriolis mass flow meter, including a base 1, a flow meter body 3 mounted on the top of the base 1, three cylinders 5 fixedly connected to one side of the flow meter body 3, a fixing plate 11 fixedly connected inside the cylinder 5, a connecting wire 10 fixedly connected to one side of the fixing plate 11, the connecting wire 10 being electrically connected to the flow meter body 3, two ends of a spring 21 being fixedly connected to two circular plates 17 respectively, and a sleeve 14 fixedly connected to the other side of the fixing plate 11.

[0023] The cylinder 5 has a box 12 inside, and four sliding grooves 15 are opened inside the box 12. Because of the sliding grooves 15, when the circular plate 17 moves, the slider 16 will slide inside the sliding groove 15. The sliding groove 15 plays the role of limiting the slider 16 and the circular plate 17, improving the stability of the movement of the circular plate 17. The slider 16 is slidably connected inside the sliding groove 15. There are three boxes 12. One side of each of the three boxes 12 is fixedly connected to wire 6, wire 7, and wire 8. One end of each of the wires 6, 7, and 8 is fixedly connected to a coil assembly 9. A shunt 2 is installed on the base 1. A double row of detection tubes 4 is installed at the bottom of the shunt 2. The coil assembly 9 is installed on the double row of detection tubes 4.

[0024] Two limiting rods 18 are slidably connected to the box body 12, and the limiting rods 18 pass through the box body 12. The telescopic rod 20 is located inside the box body 12. One end of the limiting rod 18 is fixedly connected to a hemisphere 19. Because of the hemisphere 19, when the arc surface of the hemisphere 19 contacts the inner wall of the cylinder 5, the cylinder 5 will squeeze the hemisphere 19, causing the two limiting rods 18 and the circular plate 17 to approach each other. The arc surface of the hemisphere 19 can facilitate the cylinder 5 to squeeze the hemisphere 19, thereby ensuring the smooth progress of subsequent work. The other end of the limiting rod 18 is fixedly connected to a circular plate 17. There are two circular plates 17. The telescopic rod 20 is fixedly connected between the two circular plates 17. Because of the telescopic rod 20, when the spring 21 is compressed, the telescopic rod 20 can limit the spring 21, prevent the spring 21 from bending excessively and deforming, and ensure the normal operation of the spring 21. The spring 21 is sleeved on the telescopic rod 20.

[0025] Two limiting holes 22 are provided on the cylinder 5. A connecting post 13 is provided inside the sleeve 14. One end of the connecting post 13 is designed with an arc surface. Because the connecting post 13 is designed with an arc surface, the arc surface has a guiding function, which makes it easy for the connecting post 13 to be quickly inserted into the sleeve 14, thereby improving work efficiency. The connecting post 13 is fixed to the box 12. There are four sliders 16. The circular plate 17 is fixed to two sliders 16.

[0026] The working principle of this utility model is as follows:

[0027] When it is necessary to disassemble the box 12, squeeze the two hemispheres 19 so that the two limiting rods 18 come closer to each other. At this time, the arc surface of the hemispheres 19 will contact the limiting hole 22. Then pull the box 12, and the hemispheres 19 will be squeezed and continue to come closer to each other until the limiting rods 18 are completely disengaged from the limiting hole 22. Then the box 12 can be pulled out, completing the disassembly of the box 12. When it is necessary to install the box 12, place the box 12 inside the cylinder 5 and push it. When the arc surface of the hemispheres 19 contacts the inner wall of the cylinder 5, the cylinder 5 will squeeze the hemispheres 19 so that the two limiting rods 18 contact the circular plate 17. As the two objects move closer together, the spring 21 is compressed. When the hemisphere 19 moves to the limiting hole 22, the hemisphere 19 loses the squeezing support of the cylinder 5, causing the spring 21 to reset and push the two limiting rods 18 away from each other, so that the limiting rods 18 are inserted into the inside of the limiting hole 22. At the same time, the connecting post 13 is inserted into the inside of the sleeve 14, thus completing the installation of the box 12. When the box 12 is in the installation state, the flow meter body 3 controls the operation of the coil assembly 9 through the connecting wire 10, fixing plate 11, connecting post 13, sleeve 14, box 12 and wire 6.
