水門扉に設けたのでははなはだ不経済である。<Prior art and its problems> In the past, water gate doors were generally opened and closed manually or mechanically. Although the manual method is economical, it is not easy due to the weight of the sluice gate. Therefore, various mechanical devices can be considered, such as those using an electric motor as shown in Japanese Utility Model Application No. 49-14035, and engines as shown in Japanese Utility Model Application No. 52-90341. There are some that use There is also one that uses a hydraulic motor, as disclosed in Japanese Utility Model Publication No. 61-29781, which was developed by the present applicant. However, although opening and closing work using such mechanical devices is easy, since water gates are only opened and closed a few times a year, it is necessary to install such a device on each water gate. It would be extremely uneconomical to set one up.

ることによつて行つているため、ペタルを踏み下
す初動作において大きな力を必要とする。 There is also a type of water gate, as shown in Japanese Utility Model Publication No. 59-41246, which utilizes a crank up-and-down system and a cam clutch to open and close the water gate by moving the foot up and down. This method can be said to be useful when the water gate is extremely small and installed in a place where the installation space is small. However, if the water gate is slightly larger and the amount of opening and closing is large,
Since the feet are moved up and down in the same direction, not only does it take more effort than when the feet are rotated, but the speed of opening and closing is slower than when the feet are rotated to reciprocate. However, even if a flywheel is used, in reality, the rotation is not uniform, and the power is transmitted by meshing many gears, so the initial movement of stepping down on the pedal creates a large amount of force. Requires.

タルを回転式とした方が、回転が一律となるの
で、フライホイールも小型のもでよく、一旦回転

なる。 In other words, if there is plenty of space for installation (generally there is plenty of room) and the water gate is a little large, it is better to use a rotating petal as the rotation will be uniform, so the flywheel can also be smaller. , Once you rotate it, you don't need much force after that. This means that even if you rotate your legs for a long time, you will not get tired.

にしたものである。<Means for Solving the Problems> Therefore, the petal type water gate opening/closing device according to the present invention has a spindle vertically connected to the upper part of the water gate main body, a gear screwed to the spindle,
In a water gate opening/closing device that moves the water gate up and down by rotating a drive gear meshing with this gear, two belt pulleys are arranged on the rotating shaft of the drive gear,
This belt pulley uses a switching clutch so that the rotation of any one belt pulley rotates the drive gear, a crank-shaped petal is rotatably provided in the passenger drive section with a saddle above it, and a cam clutch is attached to the crankshaft. Two belt pulleys are provided so as to face the belt pulley of the rotating shaft, and one set of opposing belt pulleys has a belt running in parallel, and the other set is a cradle, so that the petal is always on. By switching the switching clutch, the direction of rotation of the drive gear can be changed even if the pedals are rotated in the same direction, allowing the operator to open and close the water gate by rotating the pedals in the same way as pedaling a bicycle. It is something.

てある。<Example> Next, an example of the petal type water gate opening/closing device according to the present invention will be described based on the drawings. Reference numeral 1 denotes a spindle vertically connected to the upper part of the water gate main body 2. A gear 3 is screwed into the spindle 1 so as to match the threaded groove of the spindle 1, and this gear 3 meshes with a drive gear 4. Reference numeral 5 denotes a rotating shaft for rotating the drive gear 4, and a driven belt pulley 6 for forward rotation, a driven belt pulley 7 for reverse rotation, and a flywheel 8 are disposed on this rotating shaft 5. Reference numeral 9 denotes a switching clutch, and by moving the switching clutch lever 10, the rotation of either the forward rotation driven belt pulley 6 or the reverse rotation driven belt pulley 7 causes the drive gear 4 to rotate. 11 is a drive unit, 12 is a saddle of this drive unit 11, and 13
is a detachable handle. Saddle 1 of drive unit 11
A bicycle-type pedal 14 is rotatably disposed below 2. A drive belt pulley 16 for forward rotation and a drive belt pulley 17 for reverse rotation are disposed on the crankshaft in the center of the petal 14 via a cam clutch 15. The drive belt pulley 16 for forward rotation and the drive belt pulley 17 for reverse rotation are provided in parallel so as to face the driven belt pulley 6 for forward rotation and the driven belt pulley 7 for reverse rotation, respectively. A belt 18 is stretched in parallel to the belt pulley 6, and the belt 18 is crossed (in a figure 8 shape) to the reverse drive belt pulley 17 and the reverse driven driven belt pulley 7.

くてもよいことになる。<Operation> Thus, the operator sits on the saddle 12 of the drive unit 11, puts his or her feet on the petal 14, and rotates it. When the petal 14 is rotated, the drive belt wheel 1 for forward rotation
6 and the reverse drive belt pulley 17 rotate, and both the forward rotation driven belt pulley 6 and the reverse rotation driven belt pulley 7 simultaneously rotate in opposite directions due to the transmission of the belt 18. In this case, if the switching clutch 9 is switched to forward rotation using the clutch lever 10, for example, the rotation of the driven belt pulley 6 for forward rotation is transmitted to the drive gear 4 via the rotation shaft 5.
will rise. On the other hand, when the switching clutch 9 is switched to reverse rotation, the rotation of the driven belt pulley 7 for reverse rotation is transmitted to the drive gear 4, and, for example, the water gate 2 is lowered. Even if the petal 14 is always rotated in the same direction, the belt 18 is hooked in parallel on one side and hooked on the other side, so that opening and closing of the water gate 2 can be easily switched by the switching clutch 9. Furthermore, when the rotary shaft 5 rotates as described above, the flywheel 8 also rotates, and once the pedal 14 is started, it will continue to rotate due to the inertia of the flywheel 8. The effort required to rotate it is greatly reduced. Due to the action of the cam clutch 15, the flywheel 8 can continue to rotate without rotating the pedal 14, and the operator does not have to row the pedal 14 from beginning to end.

In addition to providing two belt pulleys, one set of belt pulleys facing each other has a parallel belt, and the other set has a cradle, making the work easier than the conventional petal vertical movement type. The labor required by the operator is reduced, and the rotational force is made more uniform.As a result, the water gate can be moved up and down smoothly.Furthermore, since a belt is used for drive transmission, it is no longer necessary to switch between forward and reverse directions. The structure is simplified because no special gear is required, and since the driving part and the driven part are connected by a belt, vibrations and shocks from the water gate side are not transmitted directly to the driving part, making work easier. can be done comfortably, and the safety of the workers is also high.
