Embodiment Construction

[0013] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0014] like figure 1 , figure 2 As shown, a hydraulic principle diagram of a spillway hydraulic hoist system with emergency functions, the main pump station: has two hydraulic cylinders 1 that promote the opening and closing of the spillway gate, and a hydraulic system that controls the action of the hydraulic cylinder 1. The pipeline of the main pumping station is connected with an emergency pumping station, and the hydraulic system of the main pumping station includes two sets of oil pumps 2, a motor 3 for driving the oil pump 2, an electromagnetic overflow valve 4, an electromagnetic reversing valve 5, and an electromagnetic reversing valve. The valve ...

Abstract

The invention relates to a spillway hydraulic hoist system with an emergency function, comprising a main pump station, wherein the main pump station is provided with a hydraulic cylinder used for driving the opening and closing of a gate of a spillway and a hydraulic system used for controlling the hydraulic cylinder to act; the main pump station is in pipe connection with an emergency pump station; the emergency pump station comprises a diesel engine, a hydraulic pump and a hydraulic valve group; the hydraulic valve group integrates a pressure control loop, a direction control loop and a speed control loop; the hydraulic system of the main pump station is connected with the hydraulic valve group of the emergency pump station through a quick connector, so as to realize the opening and closing operations to a hydraulic hoist by the emergency pump station. According to the spillway hydraulic hoist system with the emergency function, under the condition that a normal power source of the main pump station fails, the main pump station is communicated with the emergency pump station through the quick connector, so that the opening and closing of the spillway hydraulic hoist can still be operated, thereby improving the safe reliability of the spillway hydraulic hoist system, and the operation is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of hydraulic hoist, in particular to a spillway hydraulic hoist system with emergency function. Background technique [0002] The spillway is an important building on the barrage of a hydropower project. It is often used as the main or even the only flood discharge structure in most projects. The spillway working gate and its opening and closing equipment are the key facilities equipped with the flood discharge structure. Day, use troops for a while" role, the success rate of opening and closing operation of the gate under flood discharge conditions must reach 100%. Therefore, when equipment is configured, it must have extremely high reliability, and appropriate redundancy should be set up when necessary. Otherwise, once the operation fails due to equipment failure, it will not only endanger the safety of the entire project, but also bring disaster to the people in the upstream and downstream areas. The saf...
