Description

TECHNICAL FIELD

[0001] The utility model relates to water conservancy engineering technical field, concretely is a water conservancy gate opening and closing device. BACKGROUND

[0002] Water conservancy engineering is the general term of engineering facilities and technology for controlling and utilizing water resources to eliminate water disasters and develop water conservancy, and the water conservancy gate opening and closing device is an important component of control facilities for closing and opening the water discharge channel and water conservancy engineering buildings, which can be used to intercept water flow, control water level, regulate flow, discharge sediment and floating objects, etc.

[0003] The utility model patent application file with the publication number "CN220521254U" discloses a water conservancy gate opening and closing device, which is mainly composed of a base, a fixed support plate, a fixed seat, a motor and an auxiliary support block. The motor drives the connecting rod to rotate, and the steel wire rope is wound. The rising and falling of the gate are controlled by controlling the forward and reverse rotation of the motor.

[0004] The water conservancy gate opening and closing device disclosed in the above-mentioned file has the following defects: when the water conservancy gate opening and closing device is working, the connecting rod and the winding drum are driven to rotate by the motor, and the rising and falling of the gate are realized by winding or releasing the steel wire rope. In this process, if the steel wire rope cannot be arranged tightly and neatly on the winding drum in turn, it is easy to cause the problems of disordered rope, jumping rope and biting rope. Specifically, due to the reasons of insufficient initial winding of the steel wire rope, insufficient tension, wear of the winding drum guide groove or asynchronous lifting of the gate on both sides, the rope arrangement will be disordered (i.e. disordered rope). The disordered rope will further cause the sliding friction and abnormal extrusion of the steel wire rope on the surface of the winding drum. In severe cases, the subsequent rope coil will be embedded under the loose rope coil in the previous stage (i.e. biting rope), forming local shear force, which will cause damage to the structure of the steel wire rope. This problem not only accelerates the wear of the steel wire rope, but also causes abnormal transmission of the lifting force due to the disordered arrangement of the rope, which may cause the gate to lose control and fall, causing serious safety hazards.
