There is current meter supporting plate, the current meter is fixedly installed on the current meter supporting plate.
The front support rod, back stay are flexibly connected by hinge with bracket base, buoyancy tank support.
The front support rod be arranged in parallel with back stay, and the bar length of front support rod is identical with the bar length of back stay.
The current meter is cup-type current meter, and current meter is mounted by means of bolts on current meter supporting plate, current meter
Blade be more than 3, length of blade is much larger than width.
The current meter supporting plate is connected with front and rear pole by articulate, and current meter supporting plate is arranged at 3/5 depth of water.
The buoyancy tank generally upper-wide and lower-narrow type structure.
Usefulness of the present utility model：The utility model proposes a kind of mean flow rate test bracket, structure is novel, this
Utility model can save the energy using solar powered, environmental protection, mean flow rate test bracket with base be fixed on river course,
The bottom of channel.Current meter is installed on current meter supporting plate.Installation solar panel above buoyancy tank, to current meter, single-chip microcomputer,
Communication module is powered.Buoyancy tank takes structure wide at the top and narrow at the bottom, reduces the influence that resistance to water-flow is brought to measurement.It is widely used in river
The mean flow rate automatic measurement in road, channel, saves manpower, it is easy to accomplish automatic monitoring, reduces the work wind of monitoring personnel
Danger.
