It is two-layer with thin filtering grid that the filtering grid of said hand basket grid is divided into the coarse filtration grid, and the coarse filtration grid is fixed on thin filtering grid the place ahead.Adopt two-layer filtering grid that dirt is carried out twice filtration in the present technique scheme, improve filtration vessel levels, prevent to block filtration channel.
On guide rail, also be fixed with pulley, hawser connects together with the hand basket grid through promoting motor behind the pulley.Adopting pulley is the hawser channeling direction, helps the stability of hand basket grid when mentioning.
The weight of hand basket grid is greater than interim grid, and the weight of interim grid is greater than the lower limit bar.In the present technique scheme, hand basket grid, interim grid and varying in weight of lower limit bar help the fast reaction of interim grid, have avoided dirt to get into water intake conduit.
The guide rail bottom also is fixed with wheel shaft, and connecting strand is walked around wheel shaft and interim grid and lower limit bar are distributed in the wheel shaft both sides.In this skill scheme, wheel shaft has slowed down the wearing and tearing of connecting strand, helps the long-term use of this device.
Said lifting motor comprises motor and the electric control box that is connected with motor.Electric control box and motor cooperatively interact, and can regulate the lifting frequency that promotes motor, also can manually control.
Said guide rail comprises slide rail and the support that is connected with slide rail.In the present technique scheme, slide rail and support are connected to form rail body, help in use stable of guide rail.
Said slide rail is connected to form by a plurality of secondary rails.The present technique scheme makes slide rail carry out the adjustment on the length according to different working environments.
Said guide rail top is arc.In the present technique scheme, the hand basket grid changes the angle of the direction of motion and basket mouth at the guide rail top, help the discharge of dirt impurity.
The present invention has accomplished the uninterrupted automatically of water body filtered through cooperatively interacting of guide rail, hand basket grid, lifting motor and interim grid; Improved the water quality of water intaking; Saved manpower and materials, the filtering grid that has remedied during water body filters is prone to stop up, and filters not thorough, uneconomic defective.
