Problems solved by technology

At present, the centralized control of gates cannot fully realize the centralized and remote control of all types of gate hoists. It is only limited to the use of remote fiber optic wired on-site and remote automatic control of hydraulic hoists. The operation of the gate hoist can be completed in a timely manner; the gate hoist with a locking structure can only be controlled locally, and centralized and remote control cannot be realized

Embodiment 1

[0029] The lock beam of the inlet and outlet gates of a power station diversion canal weighs 120kg, and the walking mechanism weighs 120kg. The track model is 9kg / m, the wheel diameter of the running mechanism:, the running speed is ~1.5m / min, and the electric speed is 1320 rpm.

[0030] Set to reach the design speed from the start acceleration state within 1 second:

[0031] Moment of inertia: J=mR*R / 2=0.768;

[0032] Angular acceleration: α=n*360 / 57.3 / 60=138.22;

[0033] Torque: T=J*α=106.15NM;

[0034] Power: P=T*n / 9550=14.67W;

[0035] Taking the motor service coefficient as 1.5, the motor power can be initially determined as 14.67*1.5=22w;

[0036] Check the selection data of the micro motor: select the motor as 25w, select 1:10 for the middle gearbox, and 1:60 for the right-angle medium and real gearbox;

[0037] Operating speed of the operating mechanism: 1.105m / min;

[0038] Finally, the motor and its deceleration mechanism model: 25YS120DV.

[0039] The weight of the electric lockin...

Abstract

An in-situ and remote full-automatic control system of a gate hoist comprises a remote control platform, the gate hoist and an electric gate locking device. The remote control platform comprises an industrial personal computer, an in-situ PLC control cabinet and a monitoring device which are connected in sequence. The in-situ PLC control cabinet is connected with the gate hoist, the electric gate locking device and an illuminating device. The industrial personal computer is provided with a video collecting card. The in-situ PLC control cabinet is provided with a wireless communication module. By means of the in-situ and remote full-automatic control system, concentrated operation management of gates and the hoist can be achieved, and operation is easy; operation is safe, stable and reliable, and operation personnel and operation cost can be greatly reduced; and the system is suitable for operation of the gates, provided with locking structures and used for water inflow, water subsiding, working, accidents and the like, of hubs such as hydropower stations, reservoirs and channels and especially suitable for operation of long channel gates. When sudden danger occurs in the channels, the reservoirs and the like, the operation personnel can open or close the gate hoist in a control room at the first time, and accidents are prevented from occurring or expanding.

Description

technical field [0001] The invention relates to a gate with an electric locking structure for hydropower stations, reservoirs, canals and other hubs and water delivery projects, and a localized, remote, visualized, dual-channel communication system for hydraulic gate hoists and gate hoists with locking structures. And remote fully automatic remote control system. Background technique [0002] Under the premise that the country is vigorously developing water conservancy projects and long-distance water delivery projects, with the increasing level of automation, centralized and remote control has been proposed for a period of time, but the gate centralized and remote control management mode is still in the initial stage. At present, the centralized control of gates cannot fully realize the centralized and remote control of all types of gate hoists. It is only limited to the use of remote fiber optic wired on-site and remote automatic control of hydraulic hoists. The operation...
