Description

Floating type submerged riverbed water temperature monitoring equipment Technical Field The invention belongs to the technical field of riverbed water monitoring, and particularly relates to floating type submerged riverbed water temperature monitoring equipment. Background Water temperature monitoring plays a vital role in water resource management, water quality monitoring and ecological protection. The change of the water temperature directly affects the ecological environment, species distribution and water quality change of the water body, so that the real-time and accurate monitoring of the water temperature becomes a key task in various water resource projects. Especially for waters such as rivers and lakes, the change of the water temperature influences the inhabitation environment of aquatic organisms, and the change of the water temperature can be mastered in time, so that necessary data support can be provided for scientific management and ecological protection of water resources. However, conventional riverbed water temperature monitoring techniques rely primarily on fixed sensors, typically disposed on the surface of water or shallow water for measurement. The method has the problems of limited monitoring range, incapability of covering a deepwater area, inconvenient data transmission and the like. Especially under complicated water flow environment and changeable riverbed topography condition, current fixed temperature sensor often can't stably acquire comprehensive temperature data. If the data is lost or the measurement errors are caused by the equipment, the accuracy of water resource management and ecological protection is affected. In addition, conventional equipment often requires periodic maintenance and may fail after prolonged use due to water flow flushing or equipment aging, which increases operational and maintenance costs. The fixed sensor is installed on the bank or shallow water area, relies on rigid support, if it is to be laid in deep water area (such as >10 m), it will need underwater construction, with high cost and high risk. Meanwhile, the sensor is easy to be impacted by water flow in the running process, so that the bracket is inclined, and larger data deviation is generated. The existing transmission mode has obvious defects that the cable is required to be laid and broken by being flushed by water flow, maintenance is required to be carried out frequently and is required to be interrupted, single maintenance cost is high, and signal attenuation is easy to occur in a deep water area if the wireless transmission depends on an underwater base station, so that the transmission stability is poor. In addition, in complex riverbed environments (such as silt areas and rock areas), the sensors are difficult to fix firmly, shift easily to cause data loss, and influence on floating equipment is large when severe weather such as typhoons occurs.
