However, in this case, the configuration of the gearbox 314 is considerably expensive, and at least two or three workers are required to open and close the water, and a large amount of work time is required, so that a large number of emergency conditions such as flooding are required. There is a problem in that it is difficult to properly adjust the water gate.

As shown in FIG. 4 as a device for improving such a problem, the door frame 11 is provided with guides 11 'on both sides of the inner side, and the water gate 12 that is opened and closed while being raised and lowered from the guide 11'.

A hydraulic sluice opening and closing device consisting of a lock solenoid valve 22.

This device has the advantage that one worker can operate the gate in a short time, but power is required to drive the motor in order to open and close the gate by hydraulic type. In case of natural disaster such as flood, typhoon, etc. There is a high possibility that a loss of power or other power outages may occur, and in this case, there may be a situation in which the water gate cannot be operated because there is no power source for generating hydraulic pressure.

The present invention is to solve the above-mentioned problems of the prior art, to provide a hydraulic hydro-switching device that can be operated in the emergency situation when the power is not supplied due to disasters such as flood, typhoon and fire or other power plant circumstances. Mainly.

In addition, another object of the present invention is to provide a hydraulic hydro-switching device that lowers power consumption by setting the charging current differently according to the frequency of the gate opening and closing.

In order to achieve the above object, the present invention has a door frame provided with guides on both sides of the inner side, and a gate that is opened and closed while being guided and lowered through the guide, and is fixed to both sides of the gate so that the gate can be lifted and lowered.

The hydraulic sluice opening and closing device of the present invention can generate hydraulic pressure by operating the motor using the power charged in the battery, even if external power is not supplied due to natural disasters or other accidents. You can do it.

In addition, in a configuration in which two or more rectifiers flowing different currents are connected to the storage battery and charged, the administrator can set a low current to be charged in a season when the frequency of the gate is extremely low, and the frequency of the gate is high. In the season, the charging current can be set high, so that charging can be performed in a short time, so that unnecessary power consumption can be reduced while reliably managing the hydrology.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The hydraulic door opening and closing device 10 according to the first embodiment of the present invention is similar to the configuration shown in FIG. 4, the door frame 11 capable of raising and lowering the door 12 and installing the door 12 and other devices can be installed. ), A rod 13 protruding through the door frame 11, a hydraulic cylinder 14 installed at one end of the rod 13 and including a piston 16, and further comprising a door frame 11. In the upper part of the motor), an oil pump 19 for generating oil pressure by driving oil by driving the motor, an oil tank 23 for storing oil, and a rod according to opening and closing of the water gate 12 A solenoid valve 22 for selectively supplying oil depending on whether the 13 is raised or lowered is provided.

1 is a configuration diagram showing the configuration of a hydraulic hydro-switching device 10 according to a first embodiment of the present invention. As shown in FIG. 1, the hydraulic hydro-switching device according to the first embodiment of the present invention includes the rectifier 24, the storage battery 25, the power switching unit 26, and the driving means control unit 29 in the above-described configuration. It includes.

The rectifier 24 is connected to the power switching unit 26 and the storage battery by converting the external AC power into direct current.

The storage battery 25 has its input terminal connected to the output terminal of the rectifying unit 24 and its output terminal is connected to the power supply switching unit. The battery 25 is normally charged with electricity, and generates a hydraulic pressure by driving the motor 17 when a power failure occurs. It supplies the power to make it work.

Accordingly, even when a power failure occurs due to a flood or a fire, power can always be supplied to the hydrological switchgear 10, thereby preventing the risk of the hydrological switch 10 not to operate in an emergency. have.

The power switching unit 26 functions to control the on / off of the power supplied from the battery 25 together with the on / off control of the power, and the power switching unit 26 may be composed of only the switching means 28. However, it is preferable to include a power supply determining means 27 and a switching means 28 to inform the state of supply of external power.

The drive means control unit 29 functions to control the motor 17 and the solenoid valve 22 by the operator's operation.

The operation of the hydrological opening and closing device 10 of the first embodiment of the present invention will be described.

First, the motor 17 operates according to the signal of the drive means control unit 29 and oil pressure is generated by the oil pump 19 interlocked thereto. The oil supply direction is controlled according to the signal of the drive means control unit 29. It is selectively switched by a solenoid valve 22 attached to the end of the valve 30.

When the oil is supplied to the lifting chamber of the hydraulic cylinder 14, the piston of the hydraulic cylinder 14 is raised by the hydraulic pressure of the oil supplied to the lifting chamber, thereby the water gate 12 is opened.

Similarly, when the oil is supplied to the lower chamber of the hydraulic cylinder 14, the piston of the hydraulic cylinder 14 is lowered by the hydraulic pressure of the oil supplied to the lower chamber, thereby the water gate 12 is closed. In this way, the gate can be easily opened and closed by the switching operation of the operator.

If the main power is cut off due to a power failure, the operator may use the power stored in the storage battery 25 by manipulating the switch of the power switching unit 26. This makes it possible to open and close the gate in an emergency such as a power outage.

2 is a block diagram showing the configuration of the hydraulic hydro-switching device 100 according to the second embodiment of the present invention.

As shown, other configurations are the same as in the first embodiment, but in addition to the rectifying portion (hereinafter referred to as "first rectifying portion 124a") of the first embodiment (hereinafter referred to as "second rectifying portion 124b"). I say). The second rectifier 124b sets a very low current flowing in comparison with the first rectifier 124a.

The first rectifying unit 124a and the second rectifying unit 124b may be selectively selected by the operator through the switch 131.

Through such a configuration, in the case of the hydrological opening and closing device 100 according to the second embodiment, the charging of the storage battery 125 is performed through the second rectifying unit 124b at a time when the frequency of opening and closing the water gate is very low. In summer, when the opening and closing frequency of the water gate is expected to be relatively high, the storage battery 125 is charged through the first rectifying unit 124a.

According to such a configuration, since the charging battery is charged for a long time by supplying a low charging current at a time when the opening / closing frequency of the sluice is extremely low, power consumption is lowered. On the other hand, when the gate is frequently opened and closed and the probability of a power failure is high, a large amount of charging current is supplied to charge the battery over a short time, thereby making it possible to cope with a power failure.

Hydraulic hydrological switchgear according to the present invention is capable of operating the hydrological switchgear even if a power failure occurs due to a disaster, there is an advantage that can be managed reliably. In addition, the hydraulic hydrological switchgear according to the present invention has an advantage of lowering power consumption even after a long charge.
