Abstract

(57) [Summary] [Purpose] A pump capable of pumping water to a field using a water turbine rotating by the natural flow of irrigation water [Composition] A plurality of spirals with a pumping function mounted on a pedestal installed in an irrigation channel Install a turbine with a water hose.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a pump for irrigation, which fills a field with water.

[0002]

[Prior art]

 Conventionally, pumps using an electric motor or an engine as a power source have been and have been commonly used as pump devices for pouring water into rice fields, but the present invention does not use such a power source at all and the natural flow of water The pump mechanism is added to the water wheel that rotates.

[0003] There has long been a water turbine with a bucket attached to a pump for pumping, but this has not been generalized because the water turbine is large and the amount of water pumped is small and impractical. There is fairness 7-65589, but this method is also not practical because only one small suction pipe is used and only a small amount of water is pumped.

[0004]

[Problems to be solved by the invention]

 Therefore, the present invention has been made to solve the above-mentioned problems, and the purpose of the present invention is to make conventional pumping water pumping efficient and practical, and to provide a simple and inexpensive pump. To provide a water wheel pump.

[0005]

[Means for Solving the Problems]

 The present invention has the following structure to achieve the above object.The structure of the water turbine is not much different from that of the conventional one, but it is simple because it is small.A plurality of spiral water suction pipes with a pumping function are attached to this water turbine. In addition, the waterwheel is rotated by the natural flow of irrigation water, so that the water can be pumped by itself.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1 denotes a turbine blade that generates a force for rotating a water turbine in response to a water flow in an irrigation canal. The area and the number of the turbine blades 1 and the diameter of the turbine determine the rotational force of the turbine, but the pumping amount also increases. The reference numeral 2 is a blade support for supporting the water turbine blade 1. The water turbine itself has no structural difference from the conventional water turbine and is simple because the one of the present invention is small.

In FIG. 1, reference numeral 3 denotes a pipe-shaped water turbine main shaft, the water turbine main shaft 3 is supported by a bearing 4, 5 is a gantry on which a bearing 4 is mounted, and a gantry 5 is provided in a water channel. The lower part is made long so that it does not fall down because of standing, and the water turbine blade 1 is made to have a suitable height in water. Reference numeral 6 denotes a suction pipe.

FIG. 2 is an explanatory view of a mode of the water absorption pipe 7. The center of the spiral water absorption pipe 7 is connected to the water turbine main shaft 3, and the water suction port 6 is connected to the outer peripheral end of the water absorption pipe 7. The suction port 6 is fixed to the water turbine blade 1. In this case, a mounting hole is provided in the water turbine blade 1, and the water absorption pipe 7 is appropriately fastened to the blade support 2 so as not to be shaken. When running water hits the water turbine blade 1, the water turbine blade 1 is pushed and rotated. When the water turbine blade 1 with the suction port 6 rotates in water, water enters from the suction port 6 and flows into the water suction pipe 7. Although water only flows into the part located in the water, the water filled in the suction port 6 does not immediately flow into the water suction pipe 7, so that a much larger amount of water can be theoretically introduced into the water suction pipe 7, and as a pump The performance of each stage is improved.

In the present embodiment, the number of the water suction pipes 7 is two. However, if the number of water suction pipes 7 is increased, the pumping amount per one rotation of the water turbine is increased and, of course, the water suction pipe 7 becomes more efficient. Therefore, water and air alternately enter the water supply pipe 7 by the rotation of the water turbine. This air can push up the water to prevent the backflow of the water. The irrigation water flowing to the location can be pumped to the upper field.

Although the water turbine main shaft 3 is tubular, water flows to both ends. However, the unnecessary side is closed, and a water seal type rotary connection tool is provided on the other side so that a hose or the like can be connected. The present invention is not limited to such an embodiment, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.

[Effect of the invention]

 The present invention is constructed as described above, and has the following effects.It is easy to carry because of its light form. Since it is not required, it can be used freely anytime and anywhere. Power costs are of course free. The simple mechanism makes it easy to manufacture and cheap.
