Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention proposes a device which can be installed near a contaminated river to pump water by using the flowing power of the river and to purify the contamination efficiently. .

[0002]

2. Description of the Related Art Conventionally, pumping using a flow rate of a river to drive a pump is known from Japanese Utility Model Laid-Open No. 4-47166 and Japanese Patent Laid-Open No. 62-258185. The above publication also discloses that the pumped water is used for fountains in parks and irrigation in fields.

[0003]

However, in the above-mentioned publication, the pumps driven by flowing water are all installed underwater, so that installation work and maintenance are difficult. Also, in a waterway with many impurities such as a river, it is necessary to consider removing the water from the pump.

[0004]

Therefore, the present invention is to install a pump driven by the energy of flowing water on land, and to install a drive device of the pump on a water surface of a main waterway, that is, a waterway branched from a river or the like. and it was water wheel, comprising a concatenation of the impeller shaft of a motor and pump of the hydraulic turbine, and has an gist the headrace provided in the vicinity of the main water channel, wings
A water turbine with a part of the roots immersed in the water flow is provided.
Connect the pump impeller shaft to the rotating shaft,
The pump is driven by force and the suction port of the pump 6 is connected to the headrace.
Into the suction pit through which the water flows, and discharge the pump
The tank is connected to the main waterway through a septic tank.

[0005]

The device according to the present invention is constructed as described above, and since the pump and the water wheel are on the ground, maintenance and management are easy. ) It is not necessary to consider the contaminants and the like, and it is possible to perform the automatic operation without hands. In addition, the water turbine agitates the water in the headrace channel at the same time as the rotation of the water turbine, and at the same time aerates the water, thereby purifying the flowing water by increasing dissolved oxygen. Therefore,
When the main waterway is a river or the like, if the main waterway is blocked and the main water is allowed to flow through the headrace, most of the river water can be purified by the water turbine. And the water pumped by the pump,
In addition to being usable for irrigation, etc., the water in the main waterway can be purified by returning the water to the main waterway through a septic tank or the like. Hereinafter, the present invention will be specifically described with reference to the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a main waterway of a river or the like;
Is a weir provided in the main waterway 1, 3 is a waterway branched from the main waterway, 4 is a floodgate, 5 is a waterwheel provided in the waterway, and a number of blades 5a are arranged in parallel in a radial manner as shown in FIG. One unit body is formed, and the unit bodies are arranged in parallel on the rotating shaft 5b to form a front-wheel turbine having a width substantially covering the entire width of the water conduit 3 as shown in FIG. In FIG. 3, reference numerals HWL and LWL indicate a high water surface and a low water surface before and after the water turbine 5, respectively.

Next, in FIG. 1 and FIG.
Is a pump provided on one side of the water channel 3, and its impeller shaft is connected to the rotating shaft 5 b of the water wheel 5 via the transmission 7. The transmission 7 is for adjusting the rotation speed of the pump 6, and uses a continuously variable transmission to keep the rotation speed constant. In FIG. 1, reference numeral 8 denotes a water absorption pit provided near the pump 6, which is connected to the water conduit 3 by a pipe 9, and the water absorption port of the pump 6 is opened in the water absorption pit 8. Reference numeral 10 denotes a septic tank, and a pumping pipe 11 of a pump 6 is connected to the septic tank 10.
Further, the septic tank 10 is connected to the main waterway 1 by a pipe 12.

[0008] The apparatus according to the present invention is configured as described above. The water flow introduced from the main water channel 1 into the water channel 3 rotates the water turbine 5 by the water level difference HWL-LWL, and then the main water channel 1 Reflux. The water flow is stirred when the water wheel 5 rotates, and at the same time, the blades 5a of the water wheel 5 protrude from the air into the water, so that the water flow is aerated and the water in the main waterway contaminated by lack of oxygen or the like can be purified. .

On the other hand, the rotation of the water wheel 5 causes the pump 6 to rotate, to absorb the water in the water absorption pit 8, discharge the water to the purification tank 10, purify it, and then discharge it to the main waterway 1. That is, according to this invention, when the water in the main waterway 1 is contaminated, the water in the main waterway 1 is aerated by the water wheel 5 and passed through the purification tank 10 of the water pumped by the pump 6 by driving the water wheel. It can purify and purify two birds with one stone.
In addition, pumping by the pump 6 can be used for purposes other than irrigation, fountains in parks, etc. without returning to the main waterway 1.

In the pumping operation of the main waterway 1 as described above, according to the present invention, the pump 6 for pumping water is installed on the ground, and the water wheel 5 for driving the pump is also installed on the water surface. Also, the maintenance and management are easier as compared with the conventional submersible water wheel pump.

[0011]

As described above, the device according to the present invention uses the water level of the water flow in the main waterway to pump the water in the main waterway, and automatically converts both the water introduced into the headrace and the pumped water. In addition to being able to purify water, it can be used for irrigation and other purposes. In particular, the present invention has a feature that the operation part of the water turbine and the pump is on the ground, so that operation and maintenance can be easily performed.
