Weighing type water flow velocimeter

Abstract

The invention discloses a weighing type water flow velocimeter. The velocimeter a telescopic pole. A handheld electronic scale is welded at one end of the telescopic long rod. The weighing end of thehandheld electronic scale is fixedly connected with a nylon wire. One end, far away from the handheld electronic scale, of the nylon wire penetrates through the telescopic long rod and is connected with a fixed column. A stress disc is welded to one end of the fixing column, balance wings are welded to the outer walls of the two symmetrical sides of the stress disc, the fixing column is connectedwith a screw through threads, a balance column is welded to the end, away from the fixing column, of the screw, and a tip is arranged at the end, away from the screw, of the balance column. Accordingto the invention, through arranging the hand-held electronic scale, the nylon wire and the stress disc, the force-bearing disc bears the impact force of water to the force-bearing disc in flowing water, the force-bearing disc is connected with the handheld electronic scale through the nylon cable, so that the impact force of the water is measured, the flow velocity of the water can be obtained according to the pre-established relation between the flow velocity of the water and the impact force, and the effects that remote detection can be achieved, and personnel accidents are prevented are achieved.

Description

technical field [0001] The invention relates to the technical field of water flow speed measurement, in particular to a weighing water flow speed meter. Background technique [0002] At present, when measuring the flow velocity of a river, a propeller or a rotary cup type current meter is used to measure the flow velocity of the water flow. The current meter is installed on a fishing boat and put into the water at a certain water depth. The flow of water can be calculated by measuring the number of revolutions of the propeller or cup over a certain time interval. [0003] In the process of using the current water flow velocity measurement method in the prior art, since the detection element needs to be manually put into the water, and the data needs to be observed and tested at close range, it is easy to cause accidents. Therefore, it is urgent to design a weighing type water flow velocity measurement instrument to solve the above problems . Contents of the invention [...
