Summary of the invention
The purpose of the present invention is improving the fluid flow state at pump inlet to inhibit entrance vortex phenomenon, keep pumping plant more efficient Stable work.Because pump inlet fluid flow state be it is unstable, entrance be vortexed be also change with the time, common water conservancy diversion The limitation of plate is that cannot carry out water conservancy diversion according to the real-time fluidised form of pump inlet fluid.The present invention is a kind of intelligent guiding device, 3 D intelligent water conservancy diversion can be carried out to fluid according to the real-time fluidised form of fluid, the generation that import can be inhibited to be vortexed well, effectively Improve the hydraulic performance and cavitation performance of pump.
The present invention is to provide a kind of intelligent guiding device of the anti-vortex of pumping plant, it is mainly by guide vane one, guide vane two, guide vane Piece three, guide vane four, main shaft, protecting crust, gear one, gear two, gear three, gear four, gear five, gear six, gear seven, tooth Wheel eight, diversion pipe and special axle sleeve composition, are mainly characterized in that：The main shaft and special axle sleeve are clearance fit, in special axis Circumferencial direction, which is evenly arranged, on set is welded with eight gear shafts, gear one, gear two, gear three, gear four, gear 5 11, tooth Wheel six, gear seven, gear eight are sequentially arranged on eight gear shafts of special axle sleeve, and gear one, gear two, gear three, tooth Wheel four, gear five, gear six, gear seven, gear eight and gear one are successively intermeshed；
The guide vane one, guide vane two, guide vane three and guide vane four are installed on gear shaft；
The gear one ~ eight and special axle sleeve are mounted on and are mounted on inside protecting crust；
Guide vane one, guide vane two, guide vane three and guide vane four can be radial by the transmitting synchronous rotary between gear Swing, four blades and protecting crust can be around main shaft axial-rotations, it is possible to find guide vane of the invention both can with radial rotating, It can axially rotate, when fluid passes through guiding device, guide vane is balanced adjusting according to real-time fluid flow state, makes fluid stream State is uniform, and hydraulic loss is minimum when enabling flow through guiding device.
The working principle of the guiding device is：Guide vane one, guide vane two, guide vane three and guide vane four respectively with gear Seven, gear five, gear eight and gear two keep synchronous rotary, and rotation of the swing of guide vane with moving gear；
It is connected to gear one, the gear shaft of gear three, gear four and gear six is fixed on protecting crust, and main shaft is fixed on On diversion pipe, the entrance protecting crust of guiding device is taper streamline construction, and the cross section of guide vane is airfoil structure, to make Hydraulic loss minimizes.
Beneficial effects of the present invention are as follows：
Guiding device carries out 3 D intelligent adjusting to fluid, inhibits the import of pump well according to the real-time fluidised form of fluid It is vortexed, the hydraulic performance and cavitation performance of pump are all improved.
Detailed description of the invention Fig. 1 is guiding device principle schematic diagram of the present invention；A- axial plane figure；B- sectional view；
Fig. 2 is the structure chart of the special axle sleeve of the present invention；
Description of symbols：
