Description

TECHNICAL FIELD

[0001] The utility model relates to hydrology and environmental monitoring technical field, especially relate to a river and lake reservoir multi-index automatic monitoring ship. BACKGROUND

[0002] In the current hydrology and environmental monitoring technical field of river and lake reservoir, the monitoring of flow rate, water quality and meteorological parameters is crucial, but the existing monitoring technology faces many challenges and deficiencies.

[0003] At present, the selection of monitoring points of river and lake reservoir is often restricted by environmental conditions, resulting in that some key areas are difficult to achieve effective monitoring coverage due to complex terrain, few human traces and other factors. These areas often have urgent needs for monitoring of water quality, flow rate and other parameters, but due to the difficulty and cost of monitoring equipment layout, the current monitoring means cannot meet these needs.

[0004] In addition, the current monitoring technology mainly relies on manual operation, which not only requires a large number of human resources, but also has high operation and maintenance cost. The manual monitoring method not only has low operation efficiency, but also is limited by the professional skill quality and operation experience of personnel, so the accuracy and reliability of data cannot be guaranteed. At the same time, the frequency of manual monitoring is limited, which cannot reflect the real situation of water body in real time, and cannot meet the continuous and high-frequency monitoring needs of water quality, flow rate and other parameters.

[0005] In terms of data acquisition, the current monitoring technology often relies on fixed sampling points and fixed monitoring equipment, which not only limits the flexibility and adaptability of monitoring, but also is difficult to form comprehensive profile data. The monitoring method of fixed sampling point cannot accurately reflect the spatial distribution and dynamic change of water body parameters, and it is difficult to touch the deep parameters of water body.

[0006] For example, CN211223779U discloses a multifunctional catamaran-type unmanned aquatic environment monitoring vessel, belonging to the field of monitoring vessels. It includes a first hull, a second hull connected to the first hull, and a central platform positioned between the first and second hulls. Both the first and second hulls are equipped with power units. The central platform houses a water environment monitoring device, a central controller connected to the water environment monitoring device, and a wireless remote control device connected to the central controller. The central controller has an expansion interface. The water environment monitoring device includes real-time water quality monitoring equipment, underwater topographic measurement equipment, water flow velocity and flow rate monitoring equipment, and underwater flora and fauna monitoring equipment. This invention is simple to operate, highly stable, easy to disassemble and carry, and suitable for most rivers and lakes. In water bodies, this method greatly improves the efficiency of field water environment monitoring; however, most parameter monitoring is limited to the surface layer, making it impossible to monitor multiple depths and levels vertically, thus failing to form complete water profile data. The lack of remote terminals prevents real-time synchronous transmission of instrument monitoring data, causing data update delays at points requiring rapid response to parameter changes, limiting the timeliness and consistency of data synchronization. Furthermore, the absence of water sampling devices hinders automated multi-point water sample collection, impeding subsequent indoor analysis of water parameters and impacting the comprehensive assessment of water environmental quality.

[0007] In response to the shortcomings of existing technologies, the industry urgently needs a river, lake, and reservoir monitoring technology that can overcome environmental limitations, achieve efficient monitoring, and improve data accuracy and richness. This technology needs to be able to perform in-situ, real-time, and high-frequency measurements in areas inaccessible to human intervention, and also possess the ability to monitor multiple parameters simultaneously to meet the comprehensive monitoring needs for parameters such as river, lake, and reservoir flow velocity, water quality, and meteorological conditions.

[0008] In summary, existing river, lake, and reservoir monitoring technologies have shortcomings in areas such as monitoring site selection, data acquisition, and data utilization, failing to meet the current high standards for hydrological, water resource, and environmental monitoring. Therefore, it is necessary to develop a new type of multi-index automatic monitoring vessel for rivers, lakes, and reservoirs to compensate for the deficiencies of current monitoring technologies, enabling simultaneous monitoring of multiple parameters such as flow velocity, water quality, and meteorological data at the same location, and efficient data acquisition and transmission.
