The underground pipeline design can save land, and simultaneously, when the water level of the inland river is too high, the drainage pump station drains waterlogging, when the water level of the inland river network is too low, the water replenishing pump station and the underground pipeline replenish water, and when the inland river network is polluted, the drainage pump station and the underground pipeline replace water. In the mode, two pump stations are required to be arranged, and the occupied land area is large.
Meanwhile, the existing bidirectional tubular pump station is mainly realized by two modes, one mode is realized by adopting a tubular pump with bidirectional operation capability, namely, the tubular pump can operate in forward and reverse rotation, and generally adopts S-shaped blades or symmetrical blades, and the defect that the efficiency is far lower than that of a unidirectional tubular pump;
as in chinese patent document, application No. 201821134333.3, entitled: the utility model provides a full through-flow submerged motor pump of two-way drainage and irrigation, relate to a full through-flow submerged motor pump of two-way drainage and irrigation, which comprises a roof, place the board, go up ball bearing, lower ball bearing, go up the pivot, lower pivot, step motor, a control box, left hemisphere end cover and right hemisphere end cover, the roof repacks and gets the top of putting the mouth at the pump station, fixed connection between roof and the pump station top contact surface, the roof middle part is provided with the through-hole, it installs inside last through-hole to go up ball bearing, the inside that the bottom of going up the pivot passed last ball bearing stretches into to the work intracavity with the top middle part fixed connection of through-flow pump.
The mode adopts the one-way through-flow pump, and if the one-way through-flow pump is adopted, the one-way through-flow pump can only realize one-way drainage, so when drainage in the opposite direction is needed, the through-flow pump needs to be rotated and installed, the defects are obviously that the operation is complex, a large amount of manpower and time are consumed, meanwhile, the butt joint and sealing structure in the rotation process of the one-way through-flow pump is complex, the effect is volatile, and meanwhile, the rotating equipment is difficult to provide effective fixed support for the pump body. Therefore, it is necessary to realize efficient and convenient bidirectional drainage through reasonable arrangement.
Secondly, in order to ensure the opening and closing angle of the existing flap valve, the water energy loss is reduced by adopting a mode of reducing the weight of the flap valve; however, the flap valve is often in contact with water during operation, and the flap valve is hinged to the drainage pipeline, so that in the rotation process of the flap valve, an anti-rust layer on the surface of a hinged section is abraded, the hinged section is corroded and rusted, and the flap valve is difficult to open or close after being opened. If the dead weight of the flap valve is simply increased, more water energy is consumed to offset the dead weight of the flap valve, the drainage efficiency is reduced, and the problem that the water energy consumption is directly caused by the overlarge dead weight of the flap valve cannot be fundamentally solved.
