Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline flow measurement technology, specifically to a device for determining liquid flow rate and flow conditions. Background Technology

[0002] In industries such as petroleum and chemicals, liquid petrochemical products need to be transported via pipelines. However, these pipelines are sealed structures, and traditional flow meters can only measure the flow rate of the liquid within the pipeline, but cannot accurately determine the flow conditions within the liquid.

[0003] Furthermore, existing devices for determining liquid flow and conditions in petrochemical pipelines use flow and pressure sensors installed in the middle of the pipeline to determine the liquid flow and flow status. However, this split-structure device provides relatively limited data on liquid flow within the pipeline and cannot comprehensively determine and provide early warnings regarding liquid flow, flow conditions, pipeline pressure, and pipeline blockage. Consequently, it affects the accuracy of workers' assessment of liquid flow conditions within petrochemical pipelines. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a liquid flow rate and flow condition determination device to solve the technical problem that existing petrochemical pipeline liquid flow rate and flow condition determination devices use single flow rate data to determine the liquid flow condition in the pipeline, and cannot integrate the determination and early warning of liquid flow rate, flow condition, pipeline pressure and pipeline blockage, thus affecting the accuracy of the operator's determination of the liquid flow condition in petrochemical pipelines.

[0005] According to the technical solution provided in the embodiments of this application, a liquid flow rate and flow condition determination device includes a measuring component, which is fixed to the middle of two chemical pipelines by bolts.

[0006] The measurement component includes a flow sensor, a pressure sensor, a temperature sensor, and a vision sensor, and the flow sensor, the pressure sensor, the temperature sensor, and the vision sensor are integrated and installed inside the measurement housing;

[0007] The warning device includes an alarm sound and a light indicator, which are fixedly installed on the top casing of the measuring housing to provide audible and visual warnings for the liquid in the chemical pipeline.

[0008] Furthermore, the chassis is fixed to the top of the measuring housing by bolts.

[0009] Furthermore, a display screen is provided at the front of the chassis for displaying the collected traffic data.

[0010] Furthermore, the rear end of the chassis is equipped with several connection ports, and each of the connection ports is electrically connected to the corresponding flow sensor, pressure sensor, temperature sensor and vision sensor.

[0011] Furthermore, each of the connection ports is connected to the connection interface at the back end of the processing unit via a corresponding connection cable.

[0012] Furthermore, a solar panel is screwed onto the top of the chassis so that the solar panel can provide power to the determination device when installed outdoors.

[0013] Furthermore, the alarm sounder is installed on both sides of the chassis, while the light indicator is installed around the top of the chassis, and the warning device is electrically connected to the processing unit via a connecting cable.

[0014] Furthermore, the vision sensor is installed inside the front end of the measuring housing, while the pressure sensor is installed on both sides of the measuring housing, and the flow sensor is installed at the top and bottom ends of the measuring housing. The temperature sensor is installed at the rear end of the flow sensor on the measuring housing.

[0015] In summary, the beneficial effects of this application are as follows:

[0016] 1. By setting up a traditional single flow meter as a judgment device that integrates pressure sensor, temperature sensor and vibration sensor, the flow sensor, pressure sensor, temperature sensor and vibration sensor can simultaneously monitor the flow rate, pressure, temperature and flow conditions of liquid in chemical pipelines. This allows for timely acquisition of instantaneous flow rate, cumulative flow rate, pipeline blockage or leakage, and timely acquisition of whether water hammer, turbulence or foaming occurs in the pipeline, thereby accurately determining the flow conditions of the liquid in the pipeline.

[0017] Second, by installing an early warning device on the chassis of the judgment device and electrically connecting the early warning device to the processing unit, the processing unit processes the collected data information and transmits it to the early warning device in a timely manner. This allows the alarm and light indicators on the early warning device to provide early warning through sound and light, making it easier for staff to detect and handle the situation promptly.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] A device for determining liquid flow rate and flow condition, the structure of which is as follows: Figures 1-3 As shown, it includes a measuring component 100 and a processing unit 200. The measuring component 100 is fixed to the middle of two chemical pipelines 300 by bolts, and the measuring unit is electrically connected to the processing unit 200 through a connecting line, so that the data such as the liquid flow rate, pressure and temperature in the pipeline sensed by the measuring component 100 can be transmitted to the processing unit 200 in a timely manner, and then processed in the processing unit 200 for recording or early warning.

[0028] like Figure 2 and Figure 4 As shown, the measuring component 100 includes a flow sensor 110, a pressure sensor 120, a temperature sensor 130, and a vision sensor 140. The flow sensor 110, pressure sensor 120, temperature sensor 130, and vision sensor 140 are integrated and installed inside the measuring housing 150. The flow sensor 110 selects an electromagnetic flow meter, ultrasonic flow meter, vortex flow meter, or turbine flow meter, etc., according to the liquid being transported in the chemical pipeline 300, so that the flow sensor can measure the flow rate of the liquid being transported in the chemical pipeline.

[0029] like Figure 4 As shown, the pressure sensor 120 is used to measure the pipeline pressure in the chemical pipeline 300. By measuring the pressure difference between the two chemical pipelines 300, if the pressure difference is within the range of exceeding the set threshold of 0.2 Pa but less than 0.5 Pa, it is determined that there is a blockage in the chemical pipeline 300. If the pressure difference exceeds the set threshold of more than 0.5 Pa, it is determined that there is a leak in the chemical pipeline 300.

[0030] like Figure 4 As shown, the temperature sensor 130 is used to monitor the temperature of the liquid transported in the chemical pipeline 300. Since the viscosity and density of the liquid transported in the chemical pipeline 300 will change with temperature, it will affect the liquid flow measurement in the chemical pipeline 300. At the same time, temperature is also an important parameter for the liquid flow in the chemical pipeline 300, which is used to determine the flow of the liquid in the chemical pipeline 300.

[0031] like Figure 4 As shown, depending on the monitoring requirements within the chemical pipeline 300, the vision sensor 140 can also be a vibration sensor or an ultrasonic sensor. The vibration sensor is used to determine whether a "water hammer" phenomenon occurs within the pipeline, while the ultrasonic sensor is used to determine the flow state (laminar, turbulent, or bubbles) by analyzing fluid noise. The vision sensor is used to monitor the liquid flow conditions within the chemical pipeline 300, such as liquid level, foam, and impurities.

[0032] like Figure 2 and Figure 3 As shown, the chassis 160 is fixed to the top of the measuring housing 150 with bolts, and a display screen 161 is provided at the front of the chassis 160 so that the display screen 161 can display the flow data collected by the flow sensor 110, pressure sensor 120, temperature sensor 130 and vision sensor 140 on the measuring component 100 in a timely manner. Several connection ports 162 are installed at the rear of the chassis 160, and each connection port 162 is electrically connected to the corresponding flow sensor 110, pressure sensor 120, temperature sensor 130 and vision sensor 140. Each connection port 162 is connected to the connection interface at the rear of the processing unit 200 through a corresponding connection cable. The microprocessor (such as ARM) on the processing unit 200... The system uses a Cortex-M series microcontroller or a microcontroller (such as an STM32 series) to enable the flow sensor 110, pressure sensor 120, temperature sensor 130, and vision sensor 140 to transmit the sensed flow, pressure, temperature, and flow status data to the processing unit 200. The microprocessor and microcontroller's built-in judgment algorithm then performs fusion analysis on the collected multi-source data. The processor on the processing unit 200 filters the data, removes obvious outliers, and integrates all sensor information to accurately determine the liquid flow status in the chemical pipeline.

[0033] like Figure 2 and Figure 3 As shown, the warning device 170 includes an alarm 171 and a light indicator 172. The alarm 171 is installed on both sides of the housing 160, while the light indicator 172 is installed around the top of the housing 160. The warning device 170 is electrically connected to the processing unit 200 via a connecting cable, so that the processing unit 200 can determine the abnormal state (such as blockage or leakage) from all sensor data, and then send the processing command to the warning device 170, so that the alarm 171 and the light indicator 172 on the warning device 170 will emit an alarm sound and a red flashing light to warn of the abnormality of the chemical pipeline 300, so that the staff can deal with or repair the chemical pipeline 300 in a timely manner.

[0034] like Figure 2 and Figure 3 As shown, a solar panel 180 is screwed onto the top of the chassis 160 so that the solar panel 180 can provide power to the internal components of the determination device when the determination device is installed outdoors. In this application, mains power or batteries can also be used for power supply.

[0035] The working principle of the liquid flow rate and flow condition determination device of this utility model is as follows:

[0036] like Figure 5 As shown, in the process of determining the flow rate and flow condition of the liquid transported in the chemical pipeline 300 by the liquid flow and flow condition determination device, the traditional determination method, which relies on a single flow meter, cannot accurately obtain the liquid flow condition within the chemical pipeline 300. By modifying the traditional single flow meter into a determination device integrating a pressure sensor 120, a temperature sensor 130, and a vibration sensor, the flow sensor 110, pressure sensor 120, temperature sensor 130, and vibration sensor can simultaneously monitor the flow rate, pressure, temperature, and flow condition of the liquid within the chemical pipeline 300, and promptly transmit the data on the flow rate, pressure, temperature, and flow condition of the liquid in the pipeline via connecting lines. The data is sent to the processing unit 200, which analyzes and processes all sensor data to obtain the instantaneous flow rate, cumulative flow rate, and pipe blockage or leakage status of the liquid in the chemical pipeline. It also promptly detects whether water hammer, turbulence, or foaming occurs in the pipeline, thereby accurately determining the flow status of the liquid in the pipeline. Simultaneously, an early warning device 170 is installed on the chassis 160 and electrically connected to the processing unit 200. After processing the collected data, the processing unit 200 promptly transmits abnormal data to the early warning device 170, so that the alarm indicator 171 and light indicator 172 on the early warning device 170 can provide audible and visual warnings, facilitating timely detection and handling by staff.

[0037] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
