Abstract
The utility model discloses a large-span plane sliding water gate comprising gate grooves (1) and a gate (2) which can slide in the gate grooves (1) up and down, wherein an opening/closing chamber (3) is arranged at the tops of the gate grooves (1); and more than two lifting lugs (4) are arranged at the top of the gate (2) which are respectively connected with each synchronous hydraulic press (5) in the opening/closing chamber (3). According to the large-span plane sliding water gate, a plurality of lifting points are used for sharing a opening/closing load of the gate so as to reduce the starting/closing capacity of each lifting point of an opening/closing machine and reduce the mid-span largest bending moment of a supporting beam of the opening/closing machine chamber in civil engineering, and therefore, the section size of the supporting beam is reduced, and the engineering investment is saved. Meanwhile, the supporting liner pressure of a sliding channel is reduced through utilizing a plurality of vertical sliding channels to bear the pressure, thereby solving the technical problem that the overgreat linear pressure causes serious abrasion on the sliding channel, solving the problem of overload operation of the large-span plane sliding water gate, and further, ensuring the safe and reliable operation of the plane water gate.
