Abstract
Description
Technical Field
[0001] This utility model relates to the field of flow monitoring equipment technology, and in particular to a multi-parameter flow monitoring device suitable for complex media. Background Technology
[0002] In many industrial production fields such as chemical industry, environmental protection, and food processing, real-time and accurate online monitoring of parameters such as flow rate, temperature, and pressure of fluids in pipelines is a key link to ensure stable production processes, ensure product quality, and achieve automated control. For this reason, various flow monitoring devices are widely used in production sites.
[0003] In actual installation and use, existing flow monitoring devices require adjustments to the monitoring position due to changes in on-site conditions. For example, monitoring points need to be set at different pipe depths for media with different viscosities or flow velocities, or the installation needs to adapt to different mounting base heights. However, many existing devices have relatively simple installation structures, often using fixed brackets or requiring manual removal of multiple bolts for position adjustment. This adjustment method is not only cumbersome and time-consuming, but also makes it difficult to achieve accurate height positioning, resulting in poor environmental adaptability of the device.
[0004] In addition, in order to obtain accurate monitoring data, the sensor probe needs to be stably placed in the fluid, especially when monitoring complex media containing particles, impurities or with high flow rates. The fluid will exert a continuous impact force on the sensor. If the sensor's fixing structure is not stable enough, this impact force will cause the sensor probe to vibrate or displace, resulting in large fluctuations and errors in the collected data, which seriously affects the reliability and accuracy of the monitoring results.
[0005] Therefore, this utility model proposes a multi-parameter flow monitoring device suitable for complex media to overcome the shortcomings of the prior art. Utility Model Content

[0011] Furthermore, the fixed frame is fixed to the outside of the monitoring tube, and the support rod connects the fixed frame and the fixed rod to place the fixed rod and the sensor installed on it inside the monitoring tube. The sensor is connected to the monitoring instrument via a data cable.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0026] Example: Please refer to Figures 1 to 4A multi-parameter flow monitoring device suitable for complex media uses a monitoring tube 1 as the flow channel carrier. The monitoring tube 1 has an inlet 307 and an outlet 308 integrally formed on its body to guide the medium flow through the device. A monitoring mechanism 3 and an adjustment mechanism 2 are cooperatively arranged on the monitoring tube 1. The monitoring mechanism 3 is used to collect information about the medium flowing through the monitoring tube 1, and the adjustment mechanism 2 is used to adjust the monitoring height of the monitoring tube 1 and provide an installation reference. The monitoring mechanism 3 includes two fixed frames 301 symmetrically fixed to both sides of the outer wall of the monitoring tube 1. Support rods 302 are fixedly connected to the fixed frames 301. The other end is fixedly connected to the fixing rod 303, which is suspended and fixed inside the cavity of the monitoring tube 1 by the support rod 302. The sensor 304 is fixedly installed on the fixing rod 303. One end of the data cable 305 is connected to the sensor 304, and the other end passes through and is connected to the monitor 306. The adjustment mechanism 2 includes a mounting block 201, a knob 202, a rotating shaft 203, a protective block 204, a worm gear 205, a gear 206, a positioning rod 207, a telescopic rod 208, a protective plate 209, and a fixing block 210. These components together constitute a transmission support assembly for height adjustment and fixation.
[0027] Please refer to Figure 3 and Figure 4 The adjustment mechanism 2 converts rotational operation into linear height change through a precise transmission and support structure. The knob 202 is coaxially fixed to one end of the rotating shaft 203. A worm gear 205 is fixed on the rotating shaft 203. The axis of the rotating shaft 203 is perpendicular to the moving direction of the positioning rod 207. The gear 206 meshes with the worm gear 205. This worm gear 205 transmission structure with self-locking function allows the rotation of the gear 206 to be precisely controlled by the worm gear 205. The gear 206 drives the positioning rod 207 to move linearly up and down through the transmission connection. The fixed block 210 is rotatably sleeved on the rotating shaft 203. The protective block 204 is fixedly connected to the fixed block 210, thus forming a protective component that can move with the rotating shaft 203. The bottom end of the positioning rod 207 abuts against or is fixed to the top outer wall of the monitoring tube 1, thereby transmitting the linear displacement of the adjustment mechanism 2 to the monitoring tube 1.
[0028] As a preferred embodiment, to provide stronger support and linkage effects, the adjustment mechanism 2 also includes a telescopic rod 208 and a protective plate 209, please refer to... Figure 1 and Figure 2 The protective plate 209 serves as a connecting platform. The top end of the protective plate 209 is fixedly connected to the top end of the positioning rod 207 and the top end of the telescopic rod 208, respectively. The bottom end of the telescopic rod 208 is hinged to the protective block 204, thereby forming a triangular support structure that can extend and retract with the height between the positioning rod 207 and the protective block 204. As another preferred embodiment, for ease of installation and integration, the monitor 306 is fixedly installed on the top surface of the protective plate 209, and the data cable 305 is laid out and fixed along the side wall of the positioning rod 207, so that the signal transmission path is clear and protected. As another preferred embodiment, in order to achieve external fixation of the device, the adjustment mechanism 2 also includes a mounting block 201, which is located on the front side of the protective block 204 and can fix the entire device to the external bracket or wall by means of bolts or snap-fit.
[0029] Working principle: When installation or adjustment of the monitoring height is required, first turn knob 202. Knob 202, through coaxial fixing, drives rotating shaft 203 to rotate synchronously. Worm gear 205, fixed to rotating shaft 203, also rotates accordingly. Since worm gear 205 and gear 206 remain meshed, the rotation of worm gear 205 drives gear 206 to rotate at a specific transmission ratio. This self-locking worm gear transmission ensures the stability of the adjustment process and the reliability of the adjusted position, preventing slippage due to vibration. 206 drives the positioning rod 207 to move precisely up and down linearly via a transmission connection. Simultaneously, the fixed block 210, rotatably mounted on the rotating shaft 203, drives the protective block 204, which is fixedly connected to it, to move up and down synchronously under guidance. The movement of the protective block 204 is further amplified by the hinged telescopic rod 208, causing it to extend and retract. Since the top ends of the telescopic rod 208 and the positioning rod 207 are both connected to the protective plate 209, the protective plate 209 remains stably supported throughout the adjustment process. The positioning rod 206... The bottom end of 7 abuts against or is fixed to the top of the monitoring tube 1, thereby transmitting the linear displacement of the entire adjustment mechanism 2 to the monitoring tube 1, realizing the stable and precise adjustment of the overall monitoring height of the monitoring tube 1. After adjustment to the predetermined position, the entire device can be stably installed in the working position by the mounting block 201 set on the front side of the protective block 204. When monitoring the flow rate, the monitoring instrument 306 fixedly installed on the protective plate 209 is turned on. The complex medium to be measured flows in from the inlet 307 of the monitoring tube 1, flows through the fixed frame 301, support rod 302 and fixed rod 303, and the sensor 304 is stably suspended and fixed inside the monitoring tube 1. The sensor 304 collects multiple parameters such as the flow rate, temperature or pressure of the medium. The collected information is transmitted in real time to the monitoring instrument 306 for processing, display and recording through the data line 305 laid along the side wall of the positioning rod 207. Finally, the medium flows out from the outlet 308. In this way, the present invention solves the problems of inconvenient adjustment of the monitoring height and unstable fixing of the sensor 304 in the prior art, and improves the convenience of monitoring and the accuracy of data.
