Screw-in type water flow comprehensive indicator for self-generating electricity by utilizing vortex-induced vibration

Abstract

The invention discloses a screw-in type water flow comprehensive indicator for self-generating electricity by utilizing vortex-induced vibration, which is characterized in that the indicator comprisesan indicator shell, a vibration rod mounting ring, a vibration device, a vibration rod adjuster, a battery pack, a circuit board and a display panel which are sequentially mounted from bottom to top;the indicator shell comprises a sealing pipe thread used for being connected with a pipeline, a vibration rod through hole used for allowing the vibration device to penetrate through the indicator shell and stretch into the pipeline, and a mounting inner cavity used for containing the vibration rod mounting ring and the vibration rod adjuster; and an adjusting groove matched with the vibration rod adjuster to enable an adjusting knob to extend out of the device is formed in the indicator shell, a mounting groove used for fixing the vibration device is formed in the vibration rod mounting ring, and the vibration device is connected with the vibration rod adjuster. According to the invention, the vibration device can generate different amplitudes and frequencies due to vortex-induced vibration, under the condition that the damping, mass, rigidity, boundaries and other factors of the structure are fixed, the amplitude, the frequency and the flow velocity have an invariable rule, and theflow velocity can be accurately measured through the rule.

Description

technical field [0001] The invention relates to the technical field of monitoring water flow, in particular to a screw-in integrated water flow indicator which uses vortex-induced vibration to generate electricity by itself. Background technique [0002] With the exploration of the earth and the expansion of cities, infrastructure is spread all over the world, and urban agglomerations are becoming larger and more complex. Submarine oil pipelines, tap water supply in remote mountain villages, urban underground fire water pipelines, and intricate transportation pipelines in modern factories all need to be monitored and monitored, and pipeline monitoring in remote and hard-to-reach areas has always been a problem . Either artificially observe, or use cables for power supply and data feedback, whether it is the former or the latter, monitoring and monitoring the flow status of pipelines is troublesome, time-consuming and labor-intensive. In contrast to cities, fire protection ...

AI Technical Summary

Problems solved by technology

Traditional water flow indicators are either mechanical feedback, unable to achieve data feedback and collection, and require human observation; or they need long-distance power supply to display their flow status and feed back data through cables, which means how long the pipeline is As far as the length of the cable is concerned, an additional base station may be required for data collection; Structurally speaking, most water flow indicators currently use saddle-shaped or clip-on type, and the installation of this type of water flow indicator needs to be done in the early stage of the pipeline , it will be time-consuming and labor-intensive if the dark transfer is carried out on the existing pipeline
