The invention relates to the field of water conservancy projects, in particular to a hydraulic drive movable dam control system with an ice pressure counteracting function. The system comprises an oil tank, an oil inflow pipeline, an ice counteracting pipeline, an electromagnetic reversing valve, a pressure sensor and a control center. One end of the oil inflow pipeline and one end of the ice counteracting pipeline are communicated with the oil tank. The other end of the oil inflow pipeline and the other end of the ice counteracting pipeline are used for being connected with a hydraulic oil cylinder of a hydraulic drive movable dam. The electromagnetic reversing valve is arranged on the ice counteracting pipeline. The pressure sensor is used for monitoring the oil pressure of hydraulic oil in the hydraulic oil cylinder of the hydraulic drive movable dam and sends a pressure monitoring signal to the control center when the oil pressure of the hydraulic oil exceeds the standard range. The control center is used for automatically switching the opening state and the closing state of the electromagnetic reversing valve according to the received pressure monitoring signal. By the adoption of the hydraulic drive movable dam control system with the ice pressure counteracting function, the purpose that ice pressure is automatically reduced is achieved, no ice breaking operation needs to be performed by workers, the labor intensity is relieved, and safety is improved.
Description
technical field [0001] The present application relates to the field of water conservancy engineering, and in particular to a control system for a hydraulically driven movable dam with retreating ice force. Background technique [0002] In the cold regions of northern my country, sluices are sometimes damaged by ice pressure in winter. Ice pressure will cause deformation of the dam surface of hinge dams and hydraulic dams, which can seriously cause severe distortion of the dam surface, fracture of metal or reinforced concrete structures, bending and deformation of supporting cylinders or rods. The gates are generally processed by air inflation, pressure water filling and mechanical ice breaking. However, the first two methods require additional installation of equipment and consume a lot of energy, while the latter has high labor intensity, unsafe factors, and great danger to personnel and machinery during implementation. Contents of the invention [0003] The present app...
