Direct-current and alternating-current universal gate hoist

Abstract

The invention relates to a direct-current and alternating-current universal gate hoist. The universal gate hoist comprises a motor, a speed reducer, an energy storage device, an inverter controller and a brake resistor, and the motor is a double-stator winding motor and is connected with mains supply; the speed reducer is connected with the motor and used for controlling the rotating speed of themotor, the first end of the inverter controller is connected with the electric energy output end of the energy storage device, the second end of the inverter controller is connected with the electricenergy input end of the motor, and the brake resistor is connected with the inverter controller. Based on that the gate hoist is connected with the mains supply, the energy storage device capable of outputting the direct current and the inversion controller for realizing reverse conversion of the direct current-alternating current are additionally arranged, the motor in the gate hoist can independently work under the condition that the alternating current is provided by the mains supply and can also independently work under the condition that the direct current output by the energy storage device is inversely converted into the alternating current, and the universal effect of the gate hoist under the direct current and alternating current conditions is achieved.

Description

technical field [0001] The invention relates to the field of water conservancy equipment, in particular to a gate hoist universal for direct current and alternating current. Background technique [0002] In water conservancy projects, gates in water conservancy projects are control facilities used to close and open discharge channels, and are an important part of hydraulic structures, which can be used to intercept water flow, control water levels, etc., and are usually used in reservoir construction projects . As the key to the action of the gate, the gate hoist (referred to as the hoist) is the driving device to realize the opening and closing of the gate. The hoist has a motor. Only through the drive of the motor to the gate can it be opened or closed under power supply conditions. Gate effect. [0003] In existing water conservancy projects, the motor power supply of the hoist is mainly provided by the grid to ensure the normal operation of the hoist. However, conside...
