Manual water flow velocity measuring device for water conservancy monitoring

Abstract

The invention discloses a manual water flow velocity measuring device for water conservancy monitoring, and relates to the technical field of water conservancy monitoring. The manual water flow velocity measuring device for water conservancy monitoring comprises a handheld rod, a speed measuring box is arranged at the lower end of the handheld rod, floating devices are arranged on the front outersurface and the rear outer surface of the speed measuring box respectively, a speed measuring device is arranged in the speed measuring box, an annunciator is arranged on the upper surface of the speed measuring box, and the lower surface of the annunciator is fixedly connected with the middle of the left end. The lower surfaces of the two semicircular blocks are fixedly connected with the middlepart of the upper surface of the speed measuring box; When the measuring device is used, an operator arrives at a measuring water area, holds the anti-skid rod with hands, puts the speed measuring boxinto water, the round blocks keep the speed measuring box horizontal, water flow flows through the speed measuring box to enable the fan blades to rotate, and the fan blades rotate to drive the rotating rod to rotate to enable the motor to work. the annunciator transmits flow rate data When the flow velocity needs to be measured in a floating mode, the floating plates on the front face and the rear face of the velocity measurement box are opened to provide buoyancy to enable the velocity measurement box to measure the water velocity in a floating mode.

Description

technical field [0001] The invention relates to the technical field of water conservancy monitoring, in particular to a manual water flow velocity measuring device for water conservancy monitoring. Background technique [0002] In daily water conservancy monitoring work, it is often necessary to monitor water flow velocity in water areas to obtain relevant data. However, most of the existing water flow velocity testers are large in size and require a lot of physical strength for the staff to operate. Therefore, a water conservancy monitoring instrument is proposed. Manual water velocity measuring device. Contents of the invention [0003] The purpose of the present invention is to provide a manual water flow rate measuring device for water conservancy monitoring, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a manual water flo...
