Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a winch for opening and closing a water gate, and more particularly, to a winch for opening and closing a water gate by a water level when the drive motor stops due to a power failure.
Generally, a water gate is installed to confine and discharge water in a river or a river dam, a reservoir bank, a seawall, etc. Most of the water gates thus installed are opened and closed by manual, semiautomatic and automatic opening and closing devices. There are electric and hydraulic systems for opening and closing the water gate.
The electric wire rope hoist type electric motor using the motor is expensive, has a larger size than the hoisting capacity, has a relatively large installation area, has a high installation cost, and is very noisy. Especially a relatively large maintenance cost is required.
In view of this point, the hydraulic lifting and lowering type hydraulic wand using the wire disclosed in Utility Model Registration No. 0329971 has a structure for transmitting the load-lifting strength of the hydraulic cylinder to the water gate using a rope. The hydraulic type water gate opening / closing apparatus disclosed in the Utility Model Registration No. 0171459 is achieved by operating a hydraulic cylinder in which the rod is connected to the water gate using hydraulic oil delivered from the oil chamber pump.
On the other hand, a hydraulic type water gate opening / closing device is disclosed in Registration Utility Model No. 0332997. The disclosed hydraulic type water gate opening / closing apparatus has a water level adjusting cylinder for adjusting a set water level, a manual operation chamber having an oil tank, and an operating handle for operating a manual hydraulic jack installed in the manual operation chamber.
In the conventional water gate opening / closing apparatus constructed as described above, when the operation of the hydraulic pump supplied to the hydraulic cylinder is stopped, when the hydraulic cylinder is used, the water gate can not be opened and closed. have.
Korean Patent Registration No. 10-0885968 discloses a sluice gate capable of selectively opening and closing a manual sluice gate and an automatic sluice gate, and Korean Patent Registration No. 1358299 discloses a device for recognizing a sluice gate, and Korean Patent Registration No. 1106281 There is a multistage conduction gate on the lake.
Since the water gate constructed as described above has a structure in which the water gate is opened and closed by the winch (lifting device), it is impossible to open and close the fault gate of the winch and the risk of safety accident due to the water gate being opened Is inherent.
The present invention relates to a winch for opening and closing a waterslide, which can prevent an accident caused by a flood because a wastewater can be opened regardless of the operation of a driving motor during a power failure.

And a rotation intermittent fastening unit provided in the housing for rotating the rotation intermittent shaft when the water level rises above a set water level and fixing the rotation of the rotation intermittent shaft when the water level is below a set water level.
In the present invention, the power interrupting unit may include: a first gear provided at an end of a corresponding drive shaft of the rotation intermittent shaft; a second gear provided at an end of the rotation intermittent shaft corresponding to the drive shaft; A third gear provided on the first gear shaft and meshing with the second gear, a fourth gear relatively smaller than the third gear, and a third gear disposed on a second gear shaft supported by the rotating member, And a fifth gear to which the first gear is engaged.
The rotation intermittent fastening unit includes a first rotary shaft provided with a brake drum on a housing and rotatably mounted on the housing. The first rotary shaft and the second end of the rotary shaft are provided with a second power A transmitting portion,
A first sprocket installed on an end of a bracket extending in a radial direction, the first sprocket being installed on a pad rotary shaft installed in the main housing; A pad having a weight member attached to one end of the pad member and having a predetermined weight and being raised and lowered at the other end of the pad member in accordance with the level of the pad; A displacement transmitting member for connecting the pad rotating shaft and the pad unit so that the unit can be closely contacted or separated,
And a chain return unit installed in the main housing for moving the main chain so that the weight member can be raised and the buoyant member can be lowered when the gate is opened.
The winch for a water gate opening / closing according to the present invention can prevent a problem caused by the opening / closing operation of the water gate when a power failure occurs, that is, an accident caused when the gate is not opened, and further, have.
