Abstract

The invention discloses a channel flow measuring device which can effectively solve the problem that the flow cannot be accurately measured due to imbalance of water flow and water level caused by blockage of water flow in a channel. Comprising a mounting frame embedded in a channel, a floating platform arranged on the mounting frame and a flow velocity measurer arranged on the floating platform, a lifting device is arranged between the mounting frame and the floating platform and comprises an upper fixing plate, a lower fixing plate and a connecting rod assembly arranged between the upper fixing plate and the lower fixing plate. The device has the advantages that the measuring device located behind the blocking position starts to work, the floating platform rises along with the water level along with continuous rising of the water level, flow velocity measurement of water flow can be guaranteed through the flow velocity measurer installed on the floating platform, and in the rising process of the floating platform, the stability of the device is improved; the flow velocity measurer can accurately measure the velocity of water flow, so that a formula is introduced to calculate the water flow in a special state.

Description

technical field [0001] The invention relates to a channel flow measurement device, which belongs to the field of channel flow monitoring equipment. Background technique [0002] When a certain position of the channel is blocked, the water flow is accumulated in the blocked position. When there is too much accumulation, it will flow above the blocked position, causing the water flow velocity of the entire channel to change, and also the height of the water level in the channel. Changes occur, and the high-speed water flow will form stratification, and the speed at the bottom of the water flow is obviously lower than the speed of the water surface. At this time, the flow velocity measurement originally set in the channel cannot reflect the flow velocity of the entire water flow, and cannot accurately and effectively measure the water flow. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a channel flow measurement device, which can effecti...
