Discharge port monitoring device with silt-resistant function

Abstract

The invention provides a discharge port monitoring device with a silt-resistant function. The discharge port monitoring device comprises a parallelogram movable frame and a silt-resistant mechanism, the movable frame comprises a top support, an underwater workbench and two movable cantilevers, the top support is horizontally and fixedly installed on the top of a monitoring section of a discharge port, the movable cantilevers are hinged to the two ends of the top support respectively, the bottom ends of the two movable cantilevers are hinged to the two ends of the underwater workbench respectively, and the top support and the underwater workbench are arranged in parallel; the silt-resistant mechanism is installed at the bottom of the underwater workbench, the silt-resistant mechanism comprises an adjustable bottom plate, a tensioning reed and a telescopic assembly, and the two ends of the tensioning reed are connected with the underwater workbench and the adjustable bottom plate, so that the underwater workbench, the adjustable bottom plate and the telescopic assembly form a triangular support with an angle capable of being opened and closed. The device can automatically keep the dynamic level of an underwater installation working face, can effectively resist silting interference of discharge port silting on instruments, and support water outlet overhaul of equipment and pipelines.

Description

technical field [0001] The invention relates to the technical field of water environment protection engineering, in particular to an outlet monitoring device with an anti-silting function. Background technique [0002] Outlet monitoring is a necessary measure to clarify the cause of pollution, carry out hierarchical traceability, conduct hazard assessment, and then implement technical governance in the process of water environment protection. The outlet monitoring device is a special device for section setting, instrument installation, and auxiliary pipeline layout of the outlet monitoring project. At present, traditional outlet devices such as Parshall trough and underwater section base have application limitations based on functional and structural reasons: [0003] 1) The installation and construction conditions are relatively harsh: the traditional device needs to cut off the flow at the outlet and drain the accumulated water before installation. Old outlets that canno...

AI Technical Summary

Problems solved by technology

Old outlets that cannot be interrupted for drainage cannot be laid out;

[0004] 2) Poor anti-silting ability: because the traditional device is fixed at the bottom of the discharge outlet monitoring section, the settled silt can easily bury the instrument and block the pipeline, so it is difficult to adapt to the discharge outlet with high sediment and impurity content, slow water flow or unstable discharge;

[0005] 3) Difficulty in maintenance and adjustment: the traditional device is fixed underwater in the monitoring section by pre-embedding

Since the working surface of the equipment on which the sensing instrument is mounted cannot get out of the water, it is quite difficult to disassemble, overhaul, and adjust the level of the sensing instrument

During maintenance and adjustment, if the drainage cannot be cut off, only diving operations can be performed.
