Abstract
The utility model provides a floodgate automatic control device, belonging to the field of a hydraulic control device. The floodgate automatic control device comprises a gate, a hydraulic cylinder, a support frame, a directional control valve, a hydraulic pump and a liquid level sensor; wherein the gate is connected with a piston rod of the hydraulic cylinder; the hydraulic cylinder is fixed on the support frame at one side of the gate; the support frame is arranged on a dam; the hydraulic cylinder is provided with an oil inlet pipeline and an oil return pipeline; the oil inlet pipeline is connected with the directional control valve; the oil return pipeline is connected with an oil tank; the directional control valve is connected with the hydraulic pump through a pipeline; the oil outlet end of the hydraulic pump is provided with an overflow valve; and the hydraulic pump and the directional control valve are connected with the liquid level sensor through a control end. The liquid level sensor respectively transmits the water level signal to the hydraulic pump and the directional control valve so as to drive the piston rod of the hydraulic cylinder to extend or retract, and realize the purpose of gate opening and closing. Compared with the prior art, the floodgate automatic control device has the characteristics of rational design, simple structure, high degree of automation and higher sensitivity; as the long-time manipulation of the working personnel is not needed, the fatigue strength of the working personnel is alleviated.
Description
(1) technical field
The utility model relates to a kind of hydraulic control device, specifically a kind of floodgate automatic controller.
(2) background technique
The form of steel wire pulling gate is mostly rotated in the flood discharge of reservoir at present with motor, in this case, when summer rainwater is more, need open a sluice gate flood discharge, in case water level excessively rapid growth and bring danger to dykes and dams, in this case, the staff need arrive operating room, Push switch, draining opens the sluices; But, more when water yield discharging, when water level sharply descends, need closed shutter, keep water retention capacity in the reservoir; During this period, the staff needs observation water level frequently, simultaneously again in the switching of operating room regulating gate, has both wasted a large amount of manpowers, has brought inconvenience to the staff again.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of automaticity height, safe and reliable floodgate automatic controller are provided.
The technological scheme that its technical problem that solves the utility model adopts is:
The floodgate automatic controller, comprise gate, oil hydraulic cylinder, supporting frame, reversing control valve, oil hydraulic pump and liquid level sensor, the piston rod of gate and oil hydraulic cylinder joins, oil hydraulic cylinder is fixed on the supporting frame that is positioned at gate one side, supporting frame is arranged on the dykes and dams, oil hydraulic cylinder is provided with in-line and return line, in-line and reversing control valve join, the return line connected tank, reversing control valve joins by pipeline and oil hydraulic pump, the oil outlet end of oil hydraulic pump is provided with relief valve, and above-mentioned oil hydraulic pump and reversing control valve all join by control end and liquid level sensor.
Above-mentioned floodgate automatic controller, the quantity of its oil hydraulic cylinder are 1-8.
Above-mentioned floodgate automatic controller, its liquid level sensor links to each other with alarm in addition.When liquid level sensor broke down, alarm equipment alarm was reminded maintainer's maintenance, in case cause danger.
Floodgate automatic controller of the present utility model compared with prior art, the beneficial effect that is produced is: reasonable in design, simple in structure, automaticity is high, sensitivity is higher, need not the staff controls for a long time, has alleviated staff's fatigue strength.
