The present invention relates to a water gate opening and closing device, and more particularly, to a manual opening and closing device that can perform the efficient opening and closing of the water gate by the direct operation of the operator does not need a power source such as a motor or engine.

In general, the conventional hydrological opening and closing device is also used a lot of automatic hydrological opening and closing device using a motor or the like as a driving source to raise and lower the rack of the gate, but the operator directly opens or closes the gate by operating the handle or lever in one or both directions Passive switchgear is widely used in case of emergency can be further secured convenience or safety, and on the other hand, the automatic switchgear device that is provided with the automatic type and the manual type can be used selectively.

The manual hydrological opening and closing device using the handle or the lever requires a lot of force because it uses only the arm muscle strength of the worker, and the repetitive rotation of the handle is cumbersome, and there is a problem that the operator's upper body and waist are burdened. .

On the other hand, the 'pedal hydrological opening and closing device' of the prior art Patent No. 10-0542272 has been proposed a technology configuration for rotating the input shaft of the water gate only by stepping on the stairs using the human foot, Figures 7 to 9 showing the configuration If briefly described as follows.

That is, the pedal 100 is in contact with the foot largely to move up and down relative to the pedal shaft (110a, 120a); As a hydrological opening and closing device comprising a switching device 200 for converting the rotational force of the pedal shaft into a rotational movement of the hydrologic input shaft connected to the hydrologic gate,

The pedal 100 has a foot rest formed at one end thereof to be in contact with the right foot (left foot) of the human body, and the pedal shafts 110a and 120a coupled to the switching device 200 so as to freely move up and down are connected to the other ends. Is formed in the, when the external force is not applied by the return spring (110b, 120b), the foot rest is made to include a right foot (left foot) support (110, 120), respectively, a predetermined angle rise.

In addition, the switching device 200 is formed in a shape surrounding the pedal shaft (110a, 120a) of the right foot (left foot) support (110, 120), spaced apart from the pedal shaft at a predetermined interval to the right ( Left) bosses 210 and 220; The pedal shaft 110a and 120a of the right foot (left foot) support and the right (left) boss (210,220) is installed between the pedal shaft and the right (left) only in the direction of the foot rest of the right foot (left foot) support A) one-way rotating means (230,240) fastening the boss, and in the opposite direction, the idler; A main gear 250 fixed at the same time to the right boss; A bearing 250a installed freely between the main gear and the pedal shaft; A transmission gear 260 meshed with the main gear, for accelerating the rotational speed of the main gear, and being freely supported by the speed change shaft 261; It is made to include a coupling gear 270 that is engaged with the shaft 300 of the sluice lifting the water gate, and is engaged with the transmission gear.

In addition, the one-way rotation means (230, 240) is composed of ratchet (231,241) and ratchet gear (232,242).

This predecessor uses the weight of the worker without the need for additional strength and increases the driving force and opening and closing speed necessary for opening and closing the gate through the transmission gear, but in order to implement this, a large number of reduction gear groups are required and practical driving is required. Even when the operator had to apply enough weight to the pedal, it showed the phenomenon of smooth driving.

In addition, the elastic force of the return spring is weakened by the repeated pedal drive, a problem arises in that the return of the pedal stepped to the correct position is not completed.

In addition, although it has been proposed to implement a stepping step, the precisely preceding statement requires that a complete external force must be removed from the contact with the foot in order for the stepping pedal to return to the correct position. The body weight was stumbled because it was necessary to remove the right foot's weight completely from the pedal in order to perform the left foot step again. In the end, this unnatural posture made it difficult to drive the floodgate effectively and provided considerable burden on the workers themselves.

In addition, in order to implement the right and left repeated intermittent driving, the complexity of the structure has been brought about by having a pedal shaft, a return spring, a boss, and a one-way rotating means all in one suit.

In addition, the manual and the hydrological opening and closing device of the present invention requires the sudden opening of the floodgate in case of emergency, that is, the power supply is interrupted due to automatic opening and closing, or sudden rain and flood, such as the preceding statement It was not suitable to implement fast opening and closing through the drive means.

The present invention is devised to solve the conventional problems as described above, the object of which is to minimize the required driving force according to the opening and closing drive using the hands and feet of the worker, anyone with a natural body can easily implement the opening and closing action of the water gate It is to provide a manual opening and closing device of a water gate.
