Description

Technical Field

[0001] This utility model relates to the field of leak detector technology, specifically a portable intelligent leak detector. Background Technology

[0002] Leak detectors, as a professional detection tool, are primarily used for detecting leaks in underground pipe networks. In the process of urbanization, underground pipe networks, such as water and gas pipelines, are becoming increasingly complex and extensive. Due to factors such as pipe aging, improper construction, or geological changes, leaks frequently occur. Leaks not only waste water resources but can also damage urban infrastructure and even threaten public safety. Therefore, timely and accurate detection of leaks is crucial for maintaining normal urban operations and conserving water resources. The emergence of portable intelligent leak detectors is precisely to meet this need. They integrate advanced sensing technology and intelligent processing systems, enabling efficient and accurate location of leaks and providing strong technical support for urban pipe network maintenance. However, traditional leak detectors have several drawbacks in terms of technology and usage. Firstly, traditional leak detectors are often bulky and inconvenient to carry, making them difficult to adapt to the complex and ever-changing detection environment of urban pipe networks. Secondly, during storage and transportation, key components of traditional leak detectors, such as probes and displays, are easily damaged by impacts, increasing usage costs and maintenance difficulty. These shortcomings severely impact the practicality and widespread adoption of leak detectors, hindering the efficient implementation of urban pipeline maintenance. Therefore, developing a portable, intelligent leak detector has become an urgent problem to be solved in the field of urban pipeline maintenance.

[0003] For example, Chinese patent CN218628849U discloses a portable leak detector. This patent achieves portability by incorporating a telescopic rod, probe, and protective components. During use, the user can adjust the probe height using the telescopic rod to adapt to different testing environments. However, this patent only addresses the portability and basic testing functions of the leak detector, without fully considering its stability and ease of deployment during use. For instance, during carrying and transportation, key components such as the display screen and probe are easily damaged by impacts, and the operation of unfolding it is relatively cumbersome and inconvenient. Therefore, we propose a portable intelligent leak detector. Utility Model Content

[0012] Compared with the prior art, this utility model provides a portable intelligent leak detector, which has the following beneficial effects:

[0013] 1. This portable intelligent listening device, compared to prior art document CN218628849U, discloses a technique for adjusting the probe height via a telescopic rod. However, CN218628849U significantly improves the portability and stability of the listening device through its ingenious unfolding component design. Traditional listening devices like CN218628849U are prone to damage to critical components such as the probe during carrying and transportation due to impacts. The unfolding component design in this application allows the listening device to fit snugly against the inner wall of the storage case, effectively preventing damage from impacts. Furthermore, the clever design of the unfolding component allows the listening device to unfold quickly and stably during use, improving the convenience and efficiency of detection. This device design offers greater protection and stability than traditional telescopic rod technology, representing a significant and substantial improvement in the portability and lifespan of the listening device.

[0014] 2. This portable intelligent leak detector, compared to prior art document CN218628849U, discloses a technology with an adjustable probe height. However, this application significantly improves the ease of use of the leak detector by optimizing the storage and unfolding mechanism. Traditional leak detectors like CN218628849U are relatively cumbersome and inconvenient to unfold. This application, through its optimized storage and unfolding mechanism, allows the leak detector to be quickly and easily unfolded during use, and the storage process is equally simple. This design not only improves the ease of use of the leak detector but also saves users time and effort. Furthermore, the optimized storage and unfolding mechanism makes the leak detector easier to carry and transport, facilitating leak detection in different locations. This device design is more convenient and practical than traditional technologies, representing a significant and substantial improvement in the user experience and market competitiveness of leak detectors.

[0041] Working Principle: First, the sliding connection design between the storage box 1 and the unfolding component enables the storage and protection of the listening device body 12. In the stored state, the tray 2 supports the listening device body 12 and fits tightly against the bottom of the inner wall of the storage box 1, effectively preventing collisions and damage during transport. When the listening device needs to be used, the opening and closing handle 16 is pulled, and the opening and closing plate 7 begins to move. The movement of the opening and closing plate 7 is transmitted to the rack 6 through the linkage of the connecting rods 8 on both sides and the second connecting rod 9. The sliding connection between the outer walls of the rack 6 on both sides and the top of the inner wall of the limiting groove 3 ensures the stable movement of the rack 6 in the horizontal direction. The lateral movement of the rack 6 is further converted into the horizontal sliding movement of the tray 2 at the bottom of the inner wall of the storage box 1 through the meshing connection of the gear 4 and the second gear 5. During this process, the rotational motion of gear 4 and the second gear 5, and their meshing with the bottom of rack 6, together provide the power for the smooth sliding of tray 2. Simultaneously, the sliding connection between limiting link 10 and the second link 9, and the design of the limiting groove 11, effectively restrict the movement trajectory of the second link 9, ensuring the stability and reliability of the entire unfolding process. Finally, when tray 2 is completely slid out of storage box 1, the leak detector body 12 is presented to the user. Key components such as display screen 13, probe interface 14, and headset interface 15 are clearly visible, facilitating quick connection of the probe and headset for leak detection. The handle 17 on the top of storage box 1 and the cushioning pad 18 on the bottom provide convenient carrying and good protection, respectively.
