In the city's underground pipe network system, pipeline leaks are like hidden blood vessel ruptures, quietly threatening water security and urban operation efficiency. Traditional detection methods show limitations in complex environments, but the Pucci L7000 pipeline leakage detector developed by Hunan Puqi Water Environment Research Institute redefines the precise boundary of underground pipe network detection with multi-dimensional technological breakthroughs.
The dilemma of traditional testing: from experience dependence to technical bottlenecks
In the operation and maintenance of urban infrastructure, underground pipeline leakage investigation has long faced three major problems:
1. Ambiguous positioning caused by noise interference: The traditional leakage rod relies on manual capture of water leakage sound, and in complex environments such as reinforced concrete and subway vibration, the background noise filtration rate is less than 10%, and the leakage signal is often masked;
2. Low efficiency of destructive excavation: only based on empirical judgment of leakage point, the positioning error is generally more than 2 meters, and multiple exploration holes need to be excavated for a single detection, which is not only time-consuming and laborious, but also easy to cause structural damage to non-leakage areas;
3. Lack of health diagnosis ability: Traditional tools can only identify obvious leakage points, and cannot detect hidden dangers such as corrosion on the inner wall of pipelines and loose interfaces, making it difficult to achieve preventive maintenance.
As a result of these problems, the leakage rate of the city's water supply network has remained high for a long time, with a national average leakage rate of 15%, and the amount of water wasted each year is equivalent to the amount of water in 100 West Lakes.
Second, the core technology of Pucci L7000: build a three-dimensional detection system
Through three technical modules: multi-sensor fusion, dual detection mode, and intelligent data analysis, Pucci L7000 realizes the whole process upgrade from leakage location to pipe network health management.
Multi-sensor matrix: full-scene adaptability detection
The equipment is equipped with four professional sensors to form a detection scheme covering different scenarios:
- Anti-interference large sensor: using nano coating technology, it can filter more than 90% of environmental noise, suitable for high-noise scenarios such as municipal pipe networks and industrial plants, and accurately capture the leakage soundprint at a depth of 5 meters underground;
-Portable square sensor: with a thickness of only 3 cm, it is specially designed for small spaces such as homes and office buildings, and can penetrate deep into the cracks of cabinets and walls to solve the problem of blind spots for indoor pipeline detection, with a detection depth of 0.5 meters;
- Anti-jamming medium sensor: simulates the principle of bat echolocation, enhances signal sensitivity through curved acoustic wave collection structure, and has a detection depth of up to 3 meters in conventional outdoor environments, with a positioning error of ≤ 15 cm;
-Portable triangular sensor: For the design of metal pipes, the magnetic base ensures a stable fit, reduces the signal attenuation caused by manual hand-held shaking, and is suitable for high-risk pipeline detection such as gas and heat.
Third, the detection paradigm change brought about by technological innovation
The application of Pucci L7000 has completely changed the three core links of underground pipe network inspection:
1. From "destructive excavation" to "minimally invasive repair": through precise positioning, the excavation area of a single leakage point is reduced from 0.5 square meters to less than 0.1 square meters by traditional methods, reducing 80% of ineffective construction and significantly reducing the damage to ground buildings and greening;
2. From "post-event plugging" to "pre-prevention": relying on the function of pressure monitoring and wall thickness detection, pipeline corrosion hazards can be found 6-12 months in advance, and with the remote early warning system of the Internet of Things, the hierarchical control of leakage risk can be realized, and the accident rate can be reduced by more than 70%;
3. From "manual experience" to "intelligent decision-making": The AI algorithm integrates millions of leakage voiceprint data, and the consistency of the detection results reaches 98%, eliminating the difference in manual judgment, and at the same time, providing a real-time dynamic basis for urban pipe network planning through cloud data sharing.
Guarding the lifeline of the city: the people's livelihood of the value of science and technology
In the construction of smart water, the technical advantages of Pucci L7000 are translated into significant social and economic benefits:
- Water conservation: Through precise leakage control, the leakage rate of a city's pipe network has been reduced from 22% to 8%, and the annual water saving can be used by 500,000 households for one year;
- Safety guarantee upgrade: In the inspection of gas and oil pipelines, more than 30% of the potential connection looseness and corrosion hazards are detected in advance to avoid explosion and pollution accidents caused by leakage;
-O&M cost optimization: The battery life of the device is up to 15 hours (-20°C~50°C wide temperature operation), the average daily detection area of a single unit is 5,000 square meters, and the comprehensive O&M cost is reduced by 60% compared with the traditional method.
As the "electronic sentinel" of the underground pipe network, the Pucci L7000 responds to the needs of infrastructure management in the process of urbanization with technological innovation. It is not only an accurate leak detector, but also the guardian of the city's lifeline - through the "eye of technology" that penetrates the surface, the hidden leakage risk is transformed into a visual safety guarantee, so that every drop of water flows more efficiently and safely. When technology and people's livelihood are deeply integrated, every accurate inspection is a solemn commitment to the sustainable development of the city, and it is also an innovative practice of China's intelligent manufacturing in the field of
