Description

Technical Field

[0001] The utility model belongs to the technical research and development field of measuring instruments, and specifically relates to a portable water conservancy project flow measurement device. Background Art

[0002] Portable water conservancy project flow measurement equipment is a device used to quickly and accurately measure water flow, mainly used in water conservancy projects, agricultural irrigation, river monitoring and other fields. Traditional flow measurement methods usually rely on fixed instruments, which are complex to install, costly and lack flexibility, and are difficult to adapt to changing field environments. By integrating high-precision sensors, data acquisition and processing modules, portable devices can obtain water flow data in real time, and transmit data to a remote monitoring center through wireless communication, realizing intelligent and convenient flow monitoring and management, significantly improving work efficiency and data accuracy.

[0003] The existing liquid flow meter for water supply pipeline (publication number: CN211626569U) generally has the following problems in use:

[0004] 1. Inconvenient to carry and transport: Delays in work progress: The measurement equipment is difficult to move quickly, which may cause delays in measurement work, especially when the measurement location needs to be changed frequently. High cost: Non-portable equipment requires more time and manpower to install and disassemble, which increases the labor and time costs of the project, so a portable flow measurement device is urgently needed.

[0005] 2. Unable to upload the monitored data in real time: Delayed decision-making: The inability to upload data in real time prevents managers from obtaining the latest flow information in a timely manner, thereby delaying decision-making and affecting the management and scheduling of water conservancy projects. Untimely emergency response: In the event of emergencies such as floods or leaks, real-time data upload is crucial. Delayed data information may lead to untimely emergency response, increase disaster losses and safety hazards. Data loss or error: During the manual collection and transmission of data, data loss, recording errors or errors may occur, affecting the accuracy and completeness of the data, so there is an urgent need for a flow measurement device that can upload monitoring data in real time.

[0006] 3. The equipment lacks an alarm device, and cannot give an alarm when the flow rate exceeds the threshold: Failure to give an early warning: When the flow rate exceeds the safety threshold, the lack of an alarm device will result in failure to give an early warning, and failure to take necessary protective measures in advance, increasing safety hazards. Delayed emergency response: In the event of emergencies such as floods, leaks or equipment failures, failure to give an alarm in time may delay emergency response, leading to the escalation of the situation, increasing losses and harm, so a flow measurement device with an alarm function is urgently needed.

[0035] Remote data transmission: Through the remote data transmission module, traffic data is uploaded to the remote monitoring center in real time, making it convenient for managers to conduct remote monitoring and analysis.

[0036] Voice alarm: When the flow rate exceeds the preset threshold, the central processing module sends out a voice alarm through the voice alarm module and the speaker to remind the on-site operators to deal with the abnormal situation in time.

[0037] Voice speaker: The voice speaker module ensures that the voice alarm can be clearly heard even in a noisy environment, thus improving the effectiveness of the alarm.

[0038] Advantages Implementation Logic

[0039] Advantages of the carrying handle: Improve portability: The carrying handle set on the back of the measuring device body provides a convenient point of force, which makes it easy for operators to quickly move the device between different measuring points. The design of the carrying handle reduces the dispersion of pressure points on the device during transportation and protects the integrity of the device structure. Reduce labor: The carrying handle reduces the physical exertion of operators when carrying the equipment, improving work comfort and efficiency.

[0040] Advantages of remote data transmission module: Real-time monitoring: Through the remote data transmission module, the device can upload the monitoring data to the remote monitoring center in real time, and the manager can view the latest data at any time, which improves the timeliness and accuracy of monitoring. Quick decision-making: The real-time uploaded data provides managers with the latest traffic information, which facilitates quick analysis and decision-making, especially in emergency situations, so that countermeasures can be taken quickly to reduce potential risks and losses.

[0041] Advantages of voice alarm module, speaker and sound output module: Immediate warning: When the flow rate exceeds the preset threshold, the voice alarm module sends a clear voice alarm through the speaker and sound output module to ensure that on-site personnel are informed of abnormal conditions in the first place. Improve safety: The voice alarm provides intuitive and easy-to-understand alarm information, especially in noisy environments, which can effectively remind operators and improve the safety of overall operations and the environment. Reduce the risk of misoperation: The voice alarm module can clearly inform specific abnormal conditions, reduce the risk of misoperation caused by misunderstanding or negligence, and ensure the accuracy and reliability of operations.
