In order to operate, pulleys 41 are provided on both sides of the sluice gate 4. Further, wire rope bases 42 are provided on both sides of the sluice gate 4 and fixedly installed at one end of the wire 5, and the other end is fixedly installed on the opening / closing structure 6.

  A transmission shaft 60 is provided in the opening / closing structure 6, the transmission shaft 60 is fixedly installed above the concrete structure 40 by a shaft base 600, and a gear 61 is provided. The gear 61 meshes with the transmission unit 62. Further, a fixed pulley 63 is provided, and the fixed pulley 63 is fixedly installed on the other end of the wire 5 so that when the transmission unit 62 is driven, the transmission shaft 60 is driven to control the opening and closing of the sluice gate. To adjust the water level inside and outside the sluice gate.

  A buoy structure 7 is also provided, and one buoy 70 is provided in the buoy slot 401 of the concrete structure 40. In addition, the water inlet / outlet port 402 is provided with the effect that the water level in the buoy slot 401 and the inner water level of the sluice gate become the same height. A tooth bar 72 is provided above the buoy rod 71, and the tooth bar 72 has one gear 73. The gear 73 meshes with the gear 75 of the manual rod 74. By providing a unidirectional bearing on the toothed wheel shaft of the manual rod 74, when the buoy is raised and the gear 73 is rotated, the gear 75 is also rotated at the same time. , And activate and open the sluice gate. When the manual rod 74 is manually operated, the two gears 72 and 75 are separated, and when the buoy resistance disappears, it immediately descends and the water level is lowered, and then the closed sluice gate is manually operated.

  The conventional sluice gates described above still require power to drive the sluice gate or drive using the power of the buoy. Therefore, the present inventor further studied the structure of a well-known sluice gate and invented this proposal in consideration of different districts, topographical differences, special needs, or considering the convenient characteristics of maintenance.

An object of the present invention is to provide a sluice gate that requires no power and can be automatically opened and closed.

  Hereinafter, a sluice gate according to an embodiment of the present invention will be described with reference to the drawings.

(One embodiment)
As shown in FIGS. 1 to 5, the sluice gate of the present invention has a gate body 1, and a water stop seal 10 is provided on the inside and the side of the gate body 1. When the gate body 1 is closed, water can be sufficiently prevented from penetrating to the outside of the gate seat 11. A shaft 12 is provided below the gate body 1, and the shaft 12 is fixedly installed on the gate body 1. The support 120 and the bush 121 are installed through the bearing 122. One end of the shaft 12 is fixedly installed at the end of the ballast rod 20 of the ballast device 2, and a coupling cover 200 is provided on the ballast rod 20 of the ballast device 2 in order to stabilize the coupling between the ballast rod 20 and the ballast device 2. The coupling cover 200 passes through the shaft 12 and is further fastened and fixed by the stopper device 201. In order to smoothly open and close the get body 1, a plurality of active shaft bases 13 are provided below the gate body 1. Each active shaft base 13 is provided with a support shaft 14, and the gate body 1 is installed on the gate base 11 and installed in the drainage channel 15. Further, a pedestal 16 that supports the top portion can be provided, and can be provided above the water channel. When the gate body 1 is fully opened, an appropriate horizontal state is maintained (as shown in FIG. 7), and it is advantageous when the gate body 1 is closed again. become.

  As shown in FIGS. 3 to 5, the ballast device 2 can be provided on one side (as shown in FIG. 1) or on both sides of the gate body 1. In another embodiment of the present invention, the ballast device 2 is provided. Are provided on both sides of the gate body 1 (as shown in FIG. 9). The ballast rod 20 is provided in the ballast device 2, and the ballast rod 20 is fixedly installed on the shaft 12 of the gate body 1 as described above. A ballast block 21 is provided at the other end of the ballast rod 20, and the weight and quantity of the ballast block 21 depend on the amount of water held by the water supply. The open time of the gate body 1 can be set freely. A buffer device 22 is provided at one end of the ballast rod 20, and as shown in FIGS. 3, 7, and 8, one end 220 is axially arranged at an appropriate position on the gate base 11, and the other end 221 is connected to the ballast device 2 described above. Fixed to the rod 20. The buffer device 22 can use a hydraulic cylinder or an air cylinder, and can prevent unreasonable high-speed opening and closing and a collision sound. The buffer device 22 is used to reduce the opening speed of the gate body 1. As shown in FIG. 4, the buffer device 22 may be provided with an adjustment valve 220 capable of adjusting the flow rate, and freely adjusts the operation of the buffer device 22.

  As shown in FIGS. 5 to 7, one end 30 of the passive rope 3 is fixedly installed on the ballast rod 20 of the ballast device 2, and the other end 31 is wound around the wire rope base 33 of the manual wheel 32. It is fixedly installed at an appropriate position on the gate base 11. When the manual wheel 32 is operated manually, the gate body 1 can be opened and closed.
