Description

Technical Field

[0001] The invention relates to the technical field of water level meters, and in particular to a microwave hydrological water level meter and a water level measuring method. Background Art

[0002] In real life, in order to ensure the normal use of water conservancy projects, optimize water resources management and prevent flood disasters, people often need to detect the water level of water bodies. In the prior art, microwave water level meters are usually used to detect the water level of water bodies. The microwave water level meter consists of a microwave source assembly and a transmitting and receiving unit, wherein a transmission cable is connected between the microwave source assembly and the transmitting and receiving unit. When the water body needs to be used, the transmitting and receiving unit must be moved first, so that the transmitting and receiving unit is moved to the upper side of the water body, and the bottom of the transmitting and receiving unit is parallel to the water body. Then the transmitting and receiving unit transmits microwaves, and the microwaves are reflected after contacting the surface of the water body. The microwaves will also be captured by the transmitting and receiving unit during the reflection process, and the microwave reaction model will be transmitted to the microwave source assembly. The signal calculation module provided in the microwave source assembly measures the intensity and reflection distance of the microwaves, thereby determining the water level of the water body.

[0003] However, in the actual use of the microwave water level meter, it is necessary to make the transmitting and receiving unit relatively close to the surface of the water body. In the actual use of the microwave water level meter, it is often necessary to move the microwave water level meter to the center of the bridge or other position at a certain height from the surface of the water body. This requires the transmission cable to drive the transmitting and receiving unit to transport a certain distance. However, when the transmission cable drives the transmitting and receiving unit to vertically unwind, first of all, when the unwinding distance is too long, it is easy for the transmission cable to become confused. In addition, because the transmitting and receiving unit mainly detects the distance between the transmitting and receiving unit and the surface of the water body during actual use, when the transmitting and receiving unit is moved over a long distance, because there is a certain distance between the transmitting and receiving unit and the microwave source assembly, it is not easy to intuitively detect the water level of the water body. Summary of the invention

[0004] 1. Technical issues to be solved

The rotating wheel meter sensor 34 is a prior art device for accurately measuring the moving length of the cable in the prior art, and is a prior art device well known to those skilled in the art. During the rotation of the rotating wheel 33, the rotating wheel on the rotating wheel meter sensor 34 is driven to rotate. According to the rotation distance of the rotating wheel, the rotating wheel meter sensor 34 displays the moving distance of the transmission cable 3, so that the user can judge the descending height of the transmitting and receiving unit 2 driven by the transmission cable 3.

[0054] The tension extrusion assembly includes a pushing member 35, a spring damper 36 is arranged between the pushing member 35 and the inner wall of the conveying frame 29, a wire pressing wheel 37 is rotatably connected inside the pushing member 35, and the wire pressing wheel 37 is in contact with the conveying cable 3.
