Description

Technical Field

[0001] The utility model relates to the technical field of water level monitoring devices, in particular to a water level monitoring device inside a sewage pool. Background Art

[0002] When monitoring the water level of a sewage pool, a radar level meter is often used because of the presence of corrosive substances in the sewage. The radar level meter is a measuring instrument based on the time-travel principle. The radar wave runs at the speed of light, and the running time can be converted into a level signal through electronic components. The probe emits a high-frequency pulse that propagates at the speed of light in space. When the pulse encounters the surface of the material, it is reflected back and received by the receiver in the meter, which converts the distance signal into a level signal.

[0003] At present, when radar level meters are used for internal water level monitoring in sewage pools, the radar level meters need to be installed in the sewage pool using an L-shaped mounting bracket. This mounting bracket is usually customized by the installer based on the size of the sewage pool body. This causes a waiting time for the customized bracket to be installed during the installation of the radar level meter, which is not conducive to the installation and use of the radar level meter in the sewage pool. In addition, the length of this mounting bracket is fixed. When the installation position of the sewage pool needs to be changed, the bracket cannot be adjusted in length according to the installation position. For this reason, we propose a device for monitoring the internal water level of a sewage pool. Utility Model Content

[0004] The main purpose of the utility model is to provide a device for monitoring the internal water level of a sewage pool. An adjusting frame is arranged at the mounting plate of a radar level gauge. A plurality of joint pipes with joint heads can be arranged between the first joint head and the last joint head of the adjusting frame for end-to-end connection. When the radar level gauge is installed at the sewage pool, it only needs to carry a plurality of groups of joint pipes to extend the bracket length required for the installation of the radar level gauge at the sewage pool. Then, the last joint pipe is installed at the last joint pipe to form the adjusting frame. The supporting ring of the adjusting frame is fixed above the sewage pool body with a perforated plate after the radar level gauge is installed to obtain support, thereby realizing the length-adjustable installation of the radar level gauge in cooperation with the adjusting frame at the sewage pool, so that the radar level gauge does not need to wait for the production of a customized bracket when being installed in the sewage pool to monitor the water level in the pool, and the problems in the background technology can be effectively solved.
