Technical Field

The invention relates to the technical field of field liquid level monitoring, in particular to a maintenance-free water level monitoring and protecting device for a field reservoir.

Background

The water level height is generally measured by a liquid level meter, most of the existing liquid level meters are used in scenes such as a water tank, an oil pipe and an indoor water tank, the water tank in the scenes is generally cleaner and is more convenient to maintain, so that a small hole is reserved at the measuring end according to the working principle of the liquid level meters for monitoring the water pressure, and the liquid level meters are required to be cleaned once a month in the scenes to ensure the normal work of the liquid level meters.

The traditional usage mode is to directly put the liquid level meter into water, take the liquid level meter out of the liquid to be measured once a month, and perform cleaning treatment, so that the liquid monitored by the liquid level meter must be relatively clean, no granular solid impurities are mixed in the liquid, and periodic maintenance is needed. The traditional liquid level meter mounting mode is generally a vertical suspension mounting mode, because the liquid level meter body is a rigid columnar joint, the measuring end is an effective measuring initial point, and if the liquid level meter is placed at a certain angle in liquid, the measuring error is large.

However, at present, forest fire prevention in China is frequent, a plurality of outdoor water reservoirs are built in a forest fire high-risk county in order to conveniently and timely fight fire, most of the water reservoirs are located in mountainous areas or places where forest areas are rare, daily management and maintenance costs are high, monitoring of the height of the water level is needed to be implemented, when the water level drops to a certain threshold value, water needs to be timely supplemented, and therefore the situation that no water is available when fire occurs is avoided. The reservoir is generally constructed roughly, a large amount of silt is often flushed into the reservoir due to the field environment, the silt at the bottom of the reservoir is thick after a period of time, the working condition of the liquid level meter can be influenced to a certain degree, and the work of the reservoir can be invalid when the reservoir is serious. The general area of this type of cistern is great, and the pond edge has a grade, and effective measuring position is generally far away apart from the pond limit, and does not have the possibility of suspension installation, so will drop into the aquatic apart from bank limit certain distance department with the level gauge, and guarantee that the level gauge measurement end is invariable apart from the bottom of the pool distance.
