Description

Technical Field

[0001] This utility model belongs to the field of transmitter technology, and in particular relates to a micro water density transmitter. Background Technology

[0002] In industrial production and many fields involving fluid monitoring, micro-water density transmitters play a crucial role. They can accurately monitor and provide feedback on the micro-water density of media within pipelines in real time, providing critical data support for production process control, quality control, and safe equipment operation. However, existing micro-water density transmitters often face some pressing technical problems during actual installation and use. These problems significantly affect the transmitter's measurement accuracy, stability, and service life, limiting its full performance.

[0003] Traditional micro water density transmitters are typically installed on pipelines using simple connection methods, such as direct threaded connections or flange connections. However, during long-term use, these connections are susceptible to loosening or displacement due to factors such as pressure fluctuations, temperature changes, and equipment vibrations within the pipeline. For example, without effective reinforcement, prolonged pressure impacts may cause the transmitter to gradually detach from its original installation position, leading to a decrease in the sealing performance between it and the pipeline connection. This not only causes media leakage, resulting in resource waste and safety hazards, but also allows external impurities to enter the transmitter, affecting its measurement accuracy and potentially causing damage and malfunction. This severely impacts the reliability and stability of the device. Therefore, a new micro water density transmitter is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a micro water density transmitter. By setting up a clamping assembly, specifically by moving a support frame parallel to the pipeline, the operator rotates a knob clockwise, causing a bidirectional threaded rod to rotate. This rotation of the threaded rod, through two moving blocks, causes two arc-shaped clamping plates to move closer together. When the two arc-shaped clamping plates are close together, they clamp and fix the pipeline. Anti-slip protrusions increase friction and improve the clamping effect. When the arc-shaped clamping plates clamp the pipeline, they also cause the transmitter body to move slightly closer to the pipeline via the support frame, thus achieving a reinforced installation of the transmitter body and the pipeline. This solves the problem of traditional micro water density transmitters typically using simple connection methods when installed on pipelines, such as direct threaded connections or flange connections. During long-term use, these connection methods are prone to loosening or displacement due to various factors such as pressure fluctuations, temperature changes, and equipment vibrations within the pipeline. For example, without effective reinforcement measures, long-term pressure impacts may cause the transmitter body to gradually detach from its original installation position, resulting in a decrease in the sealing performance between it and the pipeline connection pipe. This not only causes media leakage, resulting in resource waste and safety hazards, but also allows external impurities to enter the transmitter, affecting its measurement accuracy and potentially damaging the transmitter, rendering it unable to function properly. This seriously affects the reliability and stability of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a micro water density transmitter, including a pipeline, with a transmitter body disposed above the pipeline, and further including:

[0007] The installation mechanism is located outside the transmitter body and is used to install and connect the transmitter body to the pipeline.

[0008] The installation mechanism includes a clamping assembly for reinforcing the connection between the transmitter body and the pipeline. There are two sets of clamping assemblies, and the two sets of clamping assemblies contain the same components. The clamping assembly on the right side includes an arc-shaped clamping plate.

[0009] Furthermore, a connecting pipe is welded to the top of the pipeline, the bottom outer surface of the transmitter body is threaded to the inner wall of the connecting pipe, and a sleeve for support is welded to the bottom of the transmitter body.

[0010] Furthermore, the mounting mechanism also includes a support assembly connected to the transmitter body, the support assembly being used to support and limit the clamping assembly, and a sealing assembly abutting against the transmitter body, the sealing assembly being used to seal the connection between the transmitter body and the connecting pipe.

[0011] Furthermore, the support assembly includes a support frame, the inner ring of which is rotatably connected to a limiting slide rail, the inner wall of which is welded to the outer surface of the transmitter body, and fixing plates are welded to the four corners of the bottom of the support frame. Limiting grooves are provided on the left and right sides of the bottom of the support frame.

[0012] Furthermore, there are two arc-shaped clamps, and each of the two arc-shaped clamps has several anti-slip protrusions installed on its corresponding side. The side of the several anti-slip protrusions away from the arc-shaped clamps is in contact with the outer surface of the pipe.

[0013] Furthermore, each of the two arc-shaped clamping plates has a movable block welded to its top. The side of each movable block away from the arc-shaped clamping plate is slidably connected to the inside of the limiting groove. The two movable blocks are threaded with a bidirectional threaded rod inside. The outer surface of the bidirectional threaded rod is rotatably connected to the inside of the two right-side fixing plates. The bidirectional threaded rod passes through the front fixing plate and extends to the front. A knob is welded to the front of the bidirectional threaded rod.

[0014] The limiting groove is adapted to the top of the moving block.

[0015] Furthermore, the sealing assembly includes a sealing rubber ring, the inner ring of which contacts the outer surface of the connecting pipe, and an mounting bracket is installed on the outer ring of the sealing rubber ring. The mounting bracket is fitted over the outside of the sleeve and is connected to the sleeve by a number of mounting bolts.

[0016] The mounting bracket is concave in shape.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model features a clamping assembly. Specifically, the support frame is aligned parallel to the pipeline. The operator rotates a knob clockwise to rotate a bidirectional threaded rod. The rotation of the bidirectional threaded rod causes two moving blocks to bring two arc-shaped clamping plates closer together. When the two arc-shaped clamping plates are close together, they clamp and fix the pipeline. Anti-slip protrusions increase friction and improve the clamping effect. When the arc-shaped clamping plates clamp the pipeline, they will cause the transmitter body to move slightly closer to the pipeline through the support frame, thereby reinforcing the installation of the transmitter body and the pipeline, preventing the transmitter body from loosening or shifting, and improving the robustness and usability of the device.

[0019] 2. This utility model, by setting a sealing component, specifically, when the transmitter body is threadedly connected to the connecting pipe, the top of the connecting pipe squeezes the sealing rubber ring to make it contract, and then it expands due to its flexible rebound to fill the gap at the connection point and achieve a seal. The sealing rubber ring is connected to the sleeve by the mounting bracket and multiple mounting bolts, which is convenient for replacement, can extend the service life of the micro water density transmitter and related piping system, and improve the accuracy of measurement data.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5As shown, this utility model is a micro water density transmitter, including a pipe 111, a transmitter body 112 disposed above the pipe 111, and a mounting mechanism 2 disposed outside the transmitter body 112. The mounting mechanism 2 is used to install and connect the transmitter body 112 to the pipe 111. The mounting mechanism 2 includes clamping components 22 for reinforcing the connection between the transmitter body 112 and the pipe 111. There are two sets of clamping components 22, and the two sets of clamping components 22 contain the same components. The clamping component 22 located on the right side includes an arc-shaped clamping plate 221. A connecting pipe 113 is welded to the top of the pipe 111. The bottom outer surface of the transmitter body 112 is threadedly connected to the inner wall of the connecting pipe 113. The bottom of the transmitter body 112 is welded with... The mounting mechanism 2 includes a support assembly 21 connected to the transmitter body 112, which supports and limits the clamping assembly 22, and a sealing assembly 23 abutting against the transmitter body 112 to seal the connection between the transmitter body 112 and the connecting pipe 113. The support assembly 21 includes a support frame 211, with a limit rail 212 rotatably connected to its inner ring. The inner wall of the limit rail 212 is welded to the outer surface of the transmitter body 112. Fixing plates 214 are welded to the four corners of the bottom of the support frame 211. Limit grooves 213 are provided on the left and right sides of the bottom of the support frame 211. The number of arc-shaped clamping plates 221 is... Two arc-shaped clamps 221 each have several anti-slip protrusions 222 installed on their corresponding sides. The side of the anti-slip protrusions 222 away from the arc-shaped clamps 221 contacts the outer surface of the pipe 111. Movable blocks 225 are welded to the top of each arc-shaped clamp 221. The side of each movable block 225 away from the arc-shaped clamps 221 is slidably connected to the inside of the limiting groove 213. A two-way threaded rod 224 is threaded inside each movable block 225. The outer surface of the two-way threaded rod 224 is rotatably connected to the inside of the two right-side fixed plates 214. The two-way threaded rod 224 passes through the front fixed plate 214 and extends to the front. A knob 223 is welded to the front of the two-way threaded rod 224. The inside of the limiting groove 213 is adapted to the top of the movable block 225. The support frame is then activated. Parallel to pipe 111, the operator rotates knob 223 clockwise, causing bidirectional threaded rod 224 to rotate. The rotation of bidirectional threaded rod 224, via two moving blocks 225, causes two arc-shaped clamping plates 221 to move closer together. When the two arc-shaped clamping plates 221 move closer, they clamp and fix pipe 111. Anti-slip protrusions 222 increase friction and improve the clamping effect. When the arc-shaped clamping plates 221 clamp the pipe, they will move the transmitter body 112 slightly closer to pipe 111 via support frame 211, thus reinforcing the installation of the transmitter body 112 and pipe 111, preventing the transmitter body 112 from loosening or shifting, and improving the robustness of the device. The sealing assembly 23 includes a sealing rubber ring 231, the inner ring of which contacts the outer surface of connecting pipe 113.A mounting bracket 232 is installed around the outer ring of the sealing rubber ring 231. The mounting bracket 232 is fitted over the sleeve 114 and connected to the sleeve 114 by several mounting bolts 233. The mounting bracket 232 is concave. When the transmitter body 112 is threadedly connected to the connecting pipe 113, the top of the connecting pipe 113 compresses the sealing rubber ring 231, causing it to contract. The sealing rubber ring then expands due to its flexible rebound, filling the gap at the connection point and achieving a seal. The sealing rubber ring 231 is connected to the sleeve 114 via the mounting bracket 232 and multiple mounting bolts 233, facilitating replacement, extending the lifespan of the micro-water density transmitter and related piping systems, and improving the accuracy of measurement data.

[0031] One specific application of this embodiment is as follows: In use, the pipe 111 is first threadedly fixed to the transmitter body 112 through the connecting pipe 113. At the same time, when the transmitter body 112 and the connecting pipe 113 are threadedly connected, the top of the connecting pipe 113 will squeeze the sealing rubber ring 231. The sealing rubber ring 231 will contract under pressure. At the same time, the sealing rubber ring 231 will rebound and expand due to its own flexibility, thereby filling the gap at the connection between the transmitter body 112 and the connecting pipe 113 and sealing the connection between the transmitter body 112 and the connecting pipe 113. Meanwhile, the sealing rubber ring 231 is connected to the sleeve 114 through the mounting bracket 232 and multiple mounting bolts 233. The multiple mounting bolts 233 facilitate the replacement of the sealing rubber ring 231, thereby extending the service life of the entire micro water density transmitter and related piping system, and also improving the accuracy of the measurement data.

[0032] After the transmitter body 112 is connected and fixed to the pipeline 111, the operator moves the support frame 211 to a parallel state with the pipeline 111. Simultaneously, as the support frame 211 rotates, its inner ring rotates within the limiting slide rail 212, which provides a certain degree of limitation and stability for the support frame 211. Then, the operator rotates the knob 223 clockwise, causing knob 234 to rotate. As knob 234 rotates, it rotates within the fixed plate 214, providing support for the bidirectional threaded rod 224. The rotation of the bidirectional threaded rod 224 causes the two moving blocks 225 to move closer together. Simultaneously, as the moving blocks 225 move, their tops slide within the limiting groove 213, which provides a certain degree of limitation for the movement trajectory of the moving blocks 225. When the two moving blocks 225 move closer together... During the process, the pipe 111 is clamped and fixed. At the same time, multiple anti-slip protrusions 222 increase the friction between the arc-shaped clamp 221 and the surface of the pipe 111, thereby improving the clamping effect. When the arc-shaped clamp 221 clamps and fixes the pipe 111, the arc surface and clamping force will drive the limit slide rail 212 to move through the support frame 211. At this time, the limit slide rail 212 will drive the transmitter body 112 to move slightly closer to the pipe 111. This realizes the installation reinforcement of the transmitter body 112 and the pipe 111, preventing the transmitter body 112 from loosening or shifting. For example, without reinforcement, long-term pressure impact may cause the transmitter body 112 to gradually move away from its original installation position, resulting in a decrease in the sealing performance between it and the pipe connection pipe 113, and even affecting the measurement accuracy, thereby improving the robustness of the device.
