Description

Technical Field

[0001] The present application relates to the technical field of water level monitoring, and more specifically, to a siphon-type water level self-recording well pipe pressure automatic monitoring and control device. Background Art

[0002] Water level is a crucial element in hydrological observation. Numerous methods exist for observing and recording water levels, including float-type water level gauges combined with self-recording wells, radar water level gauges, and bubble (pressure) water level gauges. The combination of a self-recording well and a float-type water level gauge is widely used for water level observation because it provides the most stable and accurate data. While there are many types of self-recording wells, the most common is the direct-type. However, these have drawbacks such as difficult construction and susceptibility to siltation. Siphon-type self-recording wells combine these advantages. They offer excellent connectivity, allowing for timely and stable reflection of water level changes, while also effectively preventing siltation and being relatively simple to construct. However, the high negative pressure at the top of the inverted U-shaped siphon tube can easily lead to a large amount of air accumulating at the tip, compromising connectivity and even rendering the device inoperable. Previous solutions often relied on manual air extraction, a complex and labor-intensive process. Furthermore, the inability to visually monitor the air flow and pressure in the siphon tube can lead to inadequate air extraction, compromising water level accuracy. Moreover, due to the lack of automated means, air cannot be pumped out in time according to the siphon situation, and processing can only be carried out after the water level has become wrong, which causes distortion of water level data for a period of time and affects the observation accuracy.

[0003] Prior art publication CN 221594014 U provides a siphon-type water level self-recording well pipe pressure automatic monitoring and control device. This device monitors the siphon pipe status in real time at the measuring station and monitoring center, allowing for human intervention. The system also implements fully automatic adjustment. Once parameters are successfully set, the system automatically adjusts the water level and pressure within the siphon pipe. This system significantly improves the automation and modernization of the measuring station and enhances the accuracy of water level monitoring.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the siphon water inlet pipe is favored by people for its good sand discharge performance. The device uses a vacuum pump to extract negative pressure, and there is a problem of difficulty in exhausting in terms of connectivity.

[0005] In view of this, we propose a siphon type water level self-recording well pipe pressure automatic monitoring and control device. Utility Model Content
