Description

  The present invention generally relates to a diversion gate provided in a water channel. More specifically, the present invention relates to a lever-type diversion gate that allows easy adjustment of the water level.

  A diversion gate is installed at a part of the agricultural canal where water is diverted from the main canal to the branch canal. Conventionally, as a water gate, there are known a gate that manually lifts and lowers a door that covers the water outlet, a spindle gate configured to move up and down by rotating a spindle, and the like.

  However, the gate which raises / lowers the door manually has a problem that it is not easy to lock the gate when the water outlet is closed. On the other hand, although the spindle-type diversion gate has good water tightness, since the water level is adjusted by the height of the lower end of the gate, there is a problem that the water level adjustment work is not easy because it cannot be visually observed at the time of water level adjustment. is there.

  Therefore, the present invention has been devised to solve the problems of the conventional manual elevating and lowering type diversion gates and spindle type diversion gates, and is provided with a lever type diversion gate that realizes easy water level adjustment work. The purpose is to provide.

  The lever-type water gate according to claim 1 includes a circular door body having both edges accommodated in grooves of a pair of guide rails arranged along both sides of the opening of the water outlet, and one end Is firmly fixed to the door body, and a lever used for raising and lowering the door body, and a pair of door body locking means provided at locations opposed to the diameter direction of one surface of the door body. When the water gate gate is to be fixed, the door body is disposed at a position to be fixed, the lever is inclined in one direction at the position, and the door body locking means enters the groove. It is comprised so that the said door body may be fixed by doing.

  The lever-type water gate according to claim 2 of the present application is the water gate according to claim 1, wherein a pair of other door bodies are provided at different locations facing each other in the diameter direction of one surface of the door body. It further comprises a locking means.

  The lever-type water gate according to claim 3 of the present application is the water-divider gate according to claim 1 or 2, wherein the door body locking means is formed in the shape of a protruding piece protruding outward from the one surface. It is characterized by being.

  According to the lever-type water gate according to the present invention, the gate can be easily positioned / fixed by a simple operation of tilting the lever. In the lever-type water gate according to the present invention, since the door body is circular, the lever can be inclined smoothly and easily. Further, since the lever-type water gate according to the present invention has a simple structure, the manufacturing cost and the maintenance cost are low, and it can be easily repaired even when it breaks down.

  Next, with reference to drawings, the lever-type water gate according to a preferred embodiment of the present invention will be described in detail. FIG. 1A is a front view of a lever-type water gate according to a preferred embodiment of the present invention, and FIG. 1B is a plan view of the lever-type water gate according to FIG. The lever-type water diversion gate according to a preferred embodiment of the present invention generally indicated by reference numeral 10 in FIG. 1A includes a door body 12. The door body 12 has a circular overall shape that is slightly larger than the opening of the water outlet (see FIG. 2), and is preferably formed of a stainless steel plate.

  The lever-type water gate 10 is also provided with a lever 14 that is used when the door 12 is raised and lowered. The lever 14 is preferably formed of an elongated pipe member made of stainless steel, and one end thereof is firmly fixed to the approximate center of the door body 12. A grip 14a is provided at the other end of the lever 14 in consideration of convenience of operation.

  A pair of door body locking means 16 is provided on one surface of the door body 12 of the lever-type water-dividing gate 10 at a location facing the diameter direction. The door body locking means 16 is formed in the shape of a protruding piece that protrudes outward from one surface of the door body 12.

  FIG. 2 is a front view showing a water outlet where the lever-type water outlet gate 10 is installed, FIG. 3 is a perspective view showing a state where the lever-type water outlet gate 10 is installed at the water outlet, and FIG. It is sectional drawing which showed the state in which the lever-type water gate 10 is installed in the water port. A pair of guide rails 18 formed of an angle material having an L-shaped cross section is disposed along the both sides of the opening of the water diversion opening at the diversion opening where the lever type diversion gate 10 is installed. Both edges of the door body 12 of the water gate 10 are accommodated in the groove of the guide rail 18.

  Next, with reference to FIG. 5, the use of the lever-type water-dividing gate 10 configured as described above will be described. The lever-type water-dividing gate 10 is installed at the water-dividing port by accommodating both edge portions of the door body 12 in the groove of the guide rail 18. When closing the opening of the water outlet, the door body 12 is placed at a position where the opening is covered (see FIG. 5A), and then the lever 14 is tilted in one direction (FIG. 5 ( b)). At this time, since the door 12 is circular, it can be inclined smoothly and easily. When the lever 14 is tilted, the door body locking means 16 provided on the door body 12 enters the groove of the guide rail 18 and the door body 12 is fixed. When trying to open the opening of the water diverter, the inclination of the lever 14 is returned to the original position, the door body locking means 16 is removed from the groove 18, the door body 12 is raised to a position where the opening is opened, and the lever 14 is inclined and the door body 12 is fixed to the position.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, it is something.

  For example, in the above-described embodiment, the pair of door body locking means 16 are provided at locations facing one surface of the door body 12 in the diametrical direction. However, as shown in FIG. A pair of other door body locking means 16 ′ may be provided at another location. By providing the door body locking means 16 ', the door body 12 can be fixed even if the lever 14 is tilted to the left.

FIG. 1 (a) is a front view showing a lever-type water gate according to a preferred embodiment of the present invention, and FIG. 1 (b) is a plan view of the lever-type water gate according to FIG. 1 (a). It is the front view which showed the water outlet in which a lever type water outlet gate is installed. It is the perspective view which showed the state in which the lever-type water-dividing gate is installed in the water-dividing port. It is sectional drawing which showed the state in which the lever-type water-dividing gate is installed in the water-dividing port. It is a figure for demonstrating use of a lever-type water gate. It is the front view which showed the deformation | transformation form of the lever-type water gate.
