Description

Technical Field

[0001] The utility model relates to the technical field of water level observation, and more specifically, to a floating water level observer. Background Art

[0002] Water is an indispensable natural resource for human development and the material basis for the survival of mankind and all living things. With the increasing scarcity of water resources, the reality of water pollution has added to people's worries. To solve the water problems that are closely related to human social life in reality, modern water treatment technology and water treatment equipment must be used. Large-scale water treatment work generally requires large sedimentation tanks, purification tanks and other equipment. Existing sedimentation tanks and other water treatment equipment need to use water level observers to lift the water level in the observation tank when in use.

[0003] In the prior art, a water level sensor is fixed on a fixed rod, which is then inserted into the bottom of the reservoir. The fixed rod inserted into the bottom of the reservoir is easily tilted or even topples due to the water flow in the reservoir, which affects the water level detection.

The utility model welds a fixing plate on the outer ring of the bottom of the vertical pole, and welds multiple plug rods on the bottom of the vertical pole, so that the vertical pole is inserted into the bottom of the reservoir and then inserted into the bottom of the reservoir through the plug rods. At the same time, the traction rope and lead block connected to the outer ring of the traction ring are placed in the soil. The plug rods can be used to fix the vertical pole inside the reservoir more stably, ensuring the stability of the vertical pole fixation;

[0005] Then, combined with the drawings in its specification, it can be seen that when the water level detection device is used in water treatment equipment such as sedimentation tanks, the liquid level sensor is directly bound to the rod body, and it is easy for pollutants such as impurities in the water to adhere to the rod body or the sensor, causing the sensor detection value to be affected, thereby affecting the accuracy of the detection result.
