Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic flowmeters, in particular to an anti-interference and impact-resistant electromagnetic flowmeter. Background Technique

[0002] An electromagnetic flowmeter is an instrument that applies the principle of electromagnetic induction to measure the flow rate of a conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. It can be used to monitor and control the flow rate and velocity of the fluid. Through the accurate data provided by the electromagnetic flowmeter, precise control of the process can be achieved, ensuring the stability and consistency of the production process, improving production efficiency. The electromagnetic flowmeter can accurately measure the flow rate of the liquid in the pipeline. By detecting the voltage change caused when the fluid passes through the magnetic field, the electromagnetic flowmeter can monitor the flow rate and velocity of the fluid in real time, helping enterprises master the real-time situation of the fluid flow rate during the production process.

[0003] The above-mentioned existing technical solutions have the following defects: The existing electromagnetic flowmeter lacks a protective structure on the outside. Once the device is impacted, without protection, the damage to the device will affect its later use. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-interference and impact-resistant electromagnetic flowmeter.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A connecting block is fixedly connected to the outside of the support block. A cavity is opened inside the connecting block. A spring and a limiting block are arranged inside the cavity. A protective cover is arranged on the outside of the support block. A sponge pad is adhesively connected to the inner side of the protective cover. A conductive paint is sprayed on the outer surface of the protective cover.

[0007] By adopting the above technical solutions, a protective cover is added to one end of the device outside the electromagnetic flowmeter to protect the device through the protective cover. At the same time, a sponge pad is added inside. When impacted, it plays a buffering and protective function. At the same time, the conductive paint is added to prevent electromagnetic interference. At the same time, the protective cover can be engaged with the support block, and then through the cooperation of the spring and the limiting block, quick installation and engagement can be carried out.

[0008] Furthermore, wire grooves are reserved on the outer sides of both the protective cover and the sponge pad. A limiting hole is formed inside the protective cover. A second fixing ring is arranged on the outer side of the first fixing ring. Anti-slip pads are fixedly connected to the inner sides of the first fixing ring and the second fixing ring. A bolt is inserted into the first fixing ring, and a nut is threadedly connected to the outer side of the bolt.

[0009] By adopting the above technical solution, in order to ensure that the protective cover can be installed on the electromagnetic flowmeter, by snap-fitting the two fixing rings and then installing them with bolts and nuts, the fixing rings can be quickly installed.

[0010] Furthermore, two first fixing rings and two second fixing rings are respectively symmetrically arranged. Both the first fixing ring and the second fixing ring adopt a semi-circular structure, and a plurality of anti-slip pads are annularly distributed at equal intervals.

[0011] By adopting the above technical solution, through the design of the symmetrical structure, the stability after the structure is installed can be improved. The anti-slip pads can prevent the fixing rings from slipping and rotating, further improving the stability.

[0012] Furthermore, two groups of support blocks, connecting blocks, cavities, springs and limiting blocks are respectively symmetrically arranged. One side of the outer side of the support block adopts an arc-shaped structure, and the limiting block and the connecting block are movably connected by a spring.

[0013] By adopting the above technical solution, by adding the telescopic structure of the limiting block and the spring, rapid snap-fitting installation can be achieved.

[0014] Furthermore, the protective cover is sleeved on the outer side of the support block. The limiting block is snap-fitted with the limiting hole. The bolt passes through the first fixing ring and the second fixing ring and extends to the outer side of the second fixing ring.

[0015] By adopting the above technical solution, the two fixing rings are locked and fixed by bolts and nuts, which is convenient for fixing and installation.

[0016] In summary, the beneficial technical effects of the present utility model are as follows:

[0017] 1. The protective cover, conductive paint and sponge pad are adopted. The protective cover is added to the outer device position of the electromagnetic flowmeter. At the same time, in order to improve the protection effect, the sponge pad is added to the inner side of the protective cover, which can improve the buffering effect when being impacted. At the same time, the conductive paint on the outer side can prevent electromagnetic interference, producing the effects of anti-interference and anti-impact;

[0018] 2. Springs, limit blocks, support blocks, fixing rings and anti-slip pads are adopted. The two semi-circular fixing rings are butted and locked and fixed by bolts and nuts, so that the clamping structure of the protective cover can be installed and fixed. At the same time, the protective cover can be directly clamped and installed with the support block. The limit block and the limit hole can be clamped through the telescopic action of the spring. At the same time, an anti-slip pad is added inside the fixing ring to prevent the fixing ring from slipping after installation, producing a stable use effect. Description of the Drawings
