Conventionally, an overturning gate equipped with a ram cylinder actuating device supports the door body on the back via a roller by a ram cylinder consisting of a ram and a cylinder, and operates the cylinder through an oil supply/drainage hole to raise the gate. Configured to tip over. A shaft sealing gasket is provided between the ram and cylinder to prevent oil leakage and free sliding between the two, but the gasket completely prevents oil leakage due to wear and aging caused by long-term use. cannot be prevented. Therefore, in order to solve this problem, two oil chambers are formed which are partitioned by a cylinder to which the end of the rod is fixed and a ram fitted into the free end of this cylinder. Oil is sucked and discharged into the cylinder through an oil pipe communicating with the oil passage provided with the rod, and into another oil chamber through another oil pipe communicating with the oil hole provided in the cylinder. A ram cylinder operating device for an overturning gate is proposed in which an independent shaft sealing member is provided between each of the inner and outer surfaces of the ram and the outer surface of the rod and the inner surface of the cylinder. (Refer to Utility Model Publication No. 59-12271).

However, the conventional ram cylinder actuating device has a complicated structure, and there is a risk of oil leakage due to wear of the sealing members on both shafts.Also, there is a risk of valve leakage, making it impossible to completely prevent oil leakage. [Means to Solve the Problem] In view of the above-mentioned circumstances, this invention is designed to replenish oil leakage from the hydraulic cylinder device or valve for undulation drive of the overturning gate, so that the overturning gate can be operated. The system was designed to automatically return the gate to its original position, and its feature is that the hydraulic cylinder device that drives the overturning gate up and down is powered by a hydraulic pump driven by an electric motor driven by a solar battery or the like. It is configured to be driven by pressure oil, detects a predetermined part of the overturning gate drive system with a position detection sensor, and supplies hydraulic oil (pressure oil) to the hydraulic cylinder based on this detection signal. The feature is that the overturning gate is automatically returned to the upright position at a predetermined opening position.

According to this invention, under normal conditions, if an oil leak occurs and the overturning gate falls at a predetermined angle while the overturning gate is standing in a predetermined position, the detected object installed at a predetermined position in the overturning gate drive system, such as the piston rod or ram of a hydraulic cylinder, will move. This is detected by the position detection sensor, and the detection signal is input to the control device in the hydraulic unit, which starts the electric motor and drives the oil pump, opening the oil supply circuit in the event of a leak and sending the oil to the hydraulic cylinder. Pressure oil is replenished inside. Therefore, the overturning gate is erected again, and when the position detection sensor detects the detected object, the detection signal is input to the control device, the electric motor is stopped, the oil supply circuit is closed, and the overturning gate is placed in a predetermined position. Automatically returns to standing position.
At this time, if solar cells are used to store electricity, the overturning gate can be automatically reset using solar energy, which is suitable for irrigation in areas where commercial power is not available.

4 is a hydraulic cylinder device chamber provided in the embankment body 1; and 5 is a crankshaft connected to the end of the rotation shaft 3 protruding into the hydraulic cylinder manufacturing chamber 4. The crank arm 6 is wedged. Reference numeral 7 denotes a hydraulic cylinder whose base end is attached to a support bracket 8 installed in the hydraulic cylinder device chamber 4 so as to be swingable in the vertical direction via a horizontal shaft 9. The tip metal fitting 11 is connected to the crank arm 6.
It is pivotally connected to the free end of the holder via a pin 12. There is a detection object 13 near the tip metal fitting (or the tip metal fitting may also be used) of the piston rod 10.
Alternatively, a plurality of brackets 1 are installed, and a position detection sensor 14 is protruded from the inner wall surface of the hydraulic cylinder device chamber 4, and a position detection sensor 14 is located directly above the bracket (adjustable position) at the gate opening degree when the water level is normal.
5, the mounting position can be changed and adjusted. Therefore, by attaching the objects 13 to be detected at intervals of, for example, 5 degrees in the gate rotation angle, the position detection sensor 1 can be detected when the overturning gate 2 falls down by 5 degrees from the gate upright setting position at the normal water level.
4 issues a signal, and when the overturning gate 2 rises and returns to the normal water level setting position, the position detection sensor 14
can be made to issue a return signal. 1

ことができる。 Therefore, with the overturning gate 2 erected to a predetermined opening degree at a flat water level, the position detection sensor 14 is positioned and fixed, and the control device 19 is switched to automatic return operation. In this state, if a leak occurs in the hydraulic cylinder 7 or other valves, the overturning gate 2 will fall down little by little, and when it falls down about 5 degrees (arbitrarily set), the position detection sensor 14 will detect the object 13 to be detected. At the same time, the detection signal is input to the control device 19, and in the event of a leak, the oil feed pipe 25 is opened, and the hydraulic oil accumulated in the accumulator 26 is supplied to the hydraulic cylinder 7, and the piston rod 10
is driven, the overturning gate 2 is automatically returned to a predetermined opening position, and when the overturning gate 2 is returned, a signal is issued by the detection of the detected object 13 by the position detection sensor 14, and the oil feed pipe 25 path is blocked. On the other hand,
The electric motor 21 is activated by the signal from the position detection sensor 14.
is operated, hydraulic oil is sent to the accumulator 26 by the oil pump 22, and the pressure is accumulated. When a predetermined accumulated pressure is reached, the electric motor 21 is stopped. Note that the electric motor 21 and the oil pump 22 are automatically operated by the control device 19 so that the oil pressure of the accumulator 26 is always maintained at a predetermined value. Therefore, the detection sensor 14
The electric motor 21 can be operated automatically without depending on the signal.
