DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high place pumping device for supplying drinking water and other living water to people living on high points such as mountain tops, hillsides, plateaus and desert areas.
For example, the present invention relates to a high-altitude pumping device capable of sending drinking water to people living at high altitudes of about 1,000 meters or higher from the foot of an altitude of several hundred meters.

[0002]

2. Description of the Related Art Heretofore, there has been no high-altitude pumping device for supplying drinking water to an altitude of about 1000M or higher.

[0003]

Generally, an altitude of 1000M
A hose for supplying drinking water to a high place of about or higher height uses an iron pipe, a vinyl chloride pipe, etc. because the hose itself has a high internal pressure load when water is supplied with an inner diameter of 25 mm. In that case, it bursts and cannot be put to practical use at all. In addition, the inclination angle of the above-mentioned mountain is 30 ° to 90 ° depending on the place.
Due to the existence of extremely steep slopes such as °, there were problems such as difficulty in installing piping. Furthermore, it is desirable for people who use domestic water at high altitudes to transmit a large amount of water.However, the use of powerful pumps and hoses is technically problematic, and disadvantages such as high cost arise. there were.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to supply a large amount of domestic water quickly and in a desired place without using a large-sized pump. It is an object of the present invention to provide an altitude pumping device that can be used.

[0005]

The high-altitude pumping device according to the present invention includes a plunger pump which sends water from a water storage tank installed in a low place area or a foot area of a mountain to a high place in the area or the foot area. A flexible high-pressure hose is connected to each of the discharge sides of the two pumps, and the two high-pressure hoses are arranged in parallel to each other toward a high place. The two terminals of the ultra-high pressure hose are connected to one flexible ultra-high pressure hose via a connector and arranged toward a high place, and the terminals of the ultra-high pressure hose are connected to the high voltage hose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a plunger pump. In this embodiment, a three-plunger pump in which three plungers work alternately during one rotation of a crankshaft in order to equalize the delivery of water. Although the plunger pump was used, it is not necessarily limited to this. The plunger pump 1 sends out liquid by the action of a plunger reciprocating inside a cylindrical cylinder, a suction valve and a discharge valve, and the area A of the plunger, its stroke L, the number of revolutions n of the crankshaft, and the like. Then, the amount of water becomes Q = A · L · n, but is actually slightly smaller than this.

Two plunger pumps 1 are provided near a water storage tank 2 installed in a low place area or a foot area of a mountain near a water source. The motor of the plunger pump 1 uses, for example, 10 to 20 horsepower. In this example, one used 10 horsepower and the other used 20 horsepower. The reason for installing two pumps is that if one of the pumps breaks down, the other pump will be operated, and a large amount of water will be required to avoid running out of drinking water for residents at high altitudes. This is in order to be able to deal with such cases. Plunger - discharge quantity of the pump 1 is discharge pressure at 75~60L / min are employed those ^{100kgf / cm 2 ~150kgf / cm 2} . When the packing provided on the outer peripheral surface of the plunger reciprocating in the cylinder is made of copper plate or a copper alloy quenched, the packing at the time of starting the pump or the load during operation is higher than that of the conventional packing. The durability will be greatly increased. In particular, when the packing provided on the outer peripheral surface of the plunger reciprocating in the cylinder is made of a copper plate or a copper alloy quenched, the plunger is used.
Motor that operates the plunger even though the capacity of the plunger is the same
Can be used without breaking the packing even if it is changed from 10 hp to 20 hp, and the pump discharge water volume is more than double that of the 10 hp motor There is an advantage that the amount of water can be obtained and the pump can be used in a relatively compact state without increasing the size of the pump.

Reference numeral 3 denotes a flexible high-pressure hose connected to each discharge side of both pumps 1 and has an inner diameter of 25 mm. Each of the high pressure hoses 3 is 150 kg
It must be able to withstand a pressure of f / cm ² . Assuming that the entire length of the hose from the plunger pump 1 to a desired height is 1000 m, the length of the high-pressure hose 3 is about 200 m. The material of the high-pressure hose 3 is not limited as long as it is flexible, but a material made of synthetic resin or synthetic rubber is used in order to cope with a steeply inclined pipe or the like. In this embodiment, the high-pressure hose 3 is an inner tube 3a.
Is a synthetic rubber, a two-layer wire blade reinforcing layer 3b is formed on the outer peripheral surface thereof, and an outer cover -3c covering the reinforcing layer 3b is formed of a weather-resistant synthetic rubber. The high-pressure hoses 3 are connected to each other using a connecting member (not shown).

Reference numeral 4 denotes a single flexible ultra-high pressure hose having two ends of the high-pressure hose 3 connected via a forked branch connector (not shown), and having an inner diameter of 25 mm. Stuff used,
The hose 4 is arranged toward a high place. Ultra high pressure hose compared to first stage hose 3 connected to plunger pump 1
The reason for using the hose 4 is that the inner pressure of the second stage hose is higher than that of the first stage hose 3 due to the convergence from two to one, for example, 210 kgf / cm. ^Due to the cost of ^two , it must be able to withstand this. Also, one flexible ultra-high pressure hose from the high pressure hose 3
When the process proceeds to step 4, the flow velocity in the ultra-high pressure hose 4 is further increased. Assuming that the entire length of the hose from the plunger pump 1 to a desired height is 1000 m, the high-pressure hose 3
Is about 150 m in length. The reason for shortening the hose 3 in the first stage is that the load on the hose is gradually reduced if the hose is 150 m, and the hose itself is expensive. That is not a good idea.

The material of the ultrahigh pressure hose 4 is not limited as long as it is flexible, but it is made of synthetic resin or synthetic rubber in order to cope with steeply inclined pipes or the like. You. In this embodiment, the inner tube 4a of the ultra high pressure hose 4 is made of synthetic rubber, and four or more wire blade reinforcing layers 4b are formed on the outer peripheral surface thereof, and further, an outer cover covering the reinforcing layer 4b is formed. 4c was formed of a weather-resistant synthetic rubber. The connection between the ultra-high pressure hoses 4 is connected using a connecting member (not shown).

Reference numeral 5 denotes a high-pressure hose connected to the end of the ultra-high-pressure hose 4 having an inner diameter of 25 mm.
The stage 5 is arranged toward a high place, and is a so-called third stage hose. The pressure resistance, material and reinforcement structure of the hose 5 at this portion are the same as those of the high-pressure hose 3. The third stage hose 5 has the same length as the second stage hose 4, for example, 150 m. Reference numeral 6 denotes a pressure-resistant hose having an inner diameter of 25 mm connected to a terminal of the high-pressure hose 5, and a hose having a pressure resistance lower than that of the high-pressure hose 5, for example, about 70 kgf / cm ² is used. The hose 6 is arranged toward a desired high place, and is a so-called fourth stage hose. Plunger pump 1
Assuming that the entire length of the hose (from the first stage to the fourth stage) up to the desired height is 1000 m, the length of the pressure-resistant hose 6 is about 500 m. The fourth stage hose 6 is provided with a check valve (not shown) for preventing backflow of water.

In the present invention, the flexible high-pressure hoses 3 and 5 (the first stage hose and the third stage hose) and the flexible ultra-high pressure hose 4 (the first stage hose and the third stage hose) are used. Each inner peripheral surface of the two-stage hose) and the pressure-resistant hose 6 (fourth stage hose) is coated with a fluororesin coating 7 such as polytetrafluoroethylene to form each hose. -Not only the frictional resistance with the water in the pipe is reduced and the load on the motor is reduced, but also the flow velocity in each pipe can be further increased. In addition, by forming a coating 7 of a fluororesin such as the above-mentioned polytetrafluoroethylene, there is also an effect of preventing freezing in each hose. In addition, the coating 7 of the fluororesin is not limited to the inner peripheral surface of each hose, but is also applied to the inner peripheral surface of the connecting portion between the hoses and the inner peripheral surface of the check valve. Alternatively, the effect of preventing freezing in high altitude areas can be further exhibited. In the present invention, it is possible to supply drinking water at an altitude of 2000 m or higher by repeating and applying the above-described apparatus.

A pressure resistance of ² was obtained. This hose 3 was piped along the slope of the mountain. The two first-stage hoses were connected to a next-stage ultrahigh-pressure hose 4 via a bifurcated branch connector (not shown). This ultra-high pressure hose 4 used a synthetic rubber hose having an inner diameter of 25 mm, a length of 150 m and four layers of wire braid, and a pressure resistance of 210 kgf / cm ² was obtained. This hose 4 was piped along the slope of the mountain. Next, a high pressure hose 5 as a third stage hose was connected to the ultra high pressure hose 4. The same hose as the high-pressure hose 3 was used except that the length of the high-pressure hose 5 was 150 m. Finally, the pressure hose 6, which is the fourth stage hose, is made of a two-layer synthetic rubber hose having a blade not made of metal, and has a pipe length of 500 m and a pressure of 70 kgf / cm ^2.
Withstand pressure was obtained. A check valve (not shown) was provided on the way to supply water to the house at an altitude of 1000 m. At the top, the 3000L tank fills up in 20 minutes,
