The utility model content
The purpose of this utility model is exactly the defective at above-mentioned prior art, designed a kind of mechanical hook-up that can carry out meticulous adjusting to position and the angle of five-hole probe, the water level that can accurately be adjusted to probe both sides equalizing port rapidly flushes, make probe over against water (flow) direction, obtain accurate measurement data.
The purpose of this utility model is achieved through the following technical solutions, the five-hole probe regulating device, it is characterized in that, be provided with support, grip seat, five-hole probe, sliding guide, screw-nut body and worm-and-wheel gear, grip seat, five-hole probe, screw-nut body and worm-and-wheel gear are rack-mount, described screw-nut body is made of tubulose leading screw tubulose rotation set nut, nut is rack-mount, described worm-and-wheel gear is provided with worm gear, worm screw and worm screw seat, worm and wheel is connected with a joggle, worm screw is fixed on the worm screw seat, the worm screw seat is fixedlyed connected with described gripping seat, and described five-hole probe bar interts in the tubulose leading screw concentric with worm gear, and the worm screw seat is provided with guide hole and is set on the sliding guide, screw-nut body is regulated the axially-movable of five-hole probe, the rotation of worm-and-wheel gear condition five-hole probe.
Described five-hole probe is fastened on and grips on the seat, and this gripping seat both can move axially with five-hole probe, also can rotate around the shank center line of five-hole probe.
Described nut is provided with the nut handwheel, and the moving 360 ° of drives of nut handwheel revolution grip seat and move a pitch along leading screw.
Described worm screw is provided with the worm screw handwheel, and worm screw handwheel revolution drives and grips seat around 1 ° of the center line deflection of five-hole probe for moving 360 °.
The utility model is rational in infrastructure, and is novel ingenious, is used for position and the angle of five-hole probe are carried out meticulous adjusting, improves the accuracy that five-hole probe is measured flow velocity.4 parts such as gripping seat, screw-nut body, worm-and-wheel gear and support have been designed: grip seat and be used for fixedlying connected five-hole probe, screw-nut body be used for to regulate grip seat along five-hole probe axially (also be tested pipeline radially) mobile, worm-and-wheel gear is used for meticulous adjusting and grips seat around the rotation of probe rod center line, and support is used for connecting into each ingredient as a whole and fixedlying connected with tested pipeline.A fixedly connected handwheel that diameter is bigger on the screw-nut body nut, the handwheel revolution grips the mobile pitch of seat for moving 360 °, so can accurately locate five-hole probe; A fixedly connected handwheel that diameter is bigger on the worm screw of worm-and-wheel gear, the handwheel revolution grips 1 ° of seat deflection for moving 360 °, so can carry out meticulous adjusting to the deflection angle of five-hole probe.
