DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for taking water existing in deep layers such as deep water.

[0002]

2. Description of the Related Art Deep water has cleanliness, eutrophication, bottom water temperature, and the like, and contains medicinal ingredients. Therefore, deep water is pumped to the ground and used for various purposes. Conventionally, in order to take in deep water, an intake pipe is laid from the coast to the bottom of the sea, and deep water at a predetermined depth is pumped up by a water pump installed near the coast to take in water. Alternatively, as shown in FIG. 2, an intake pipe (flexible tube) b1 is attached to a mooring body composed of a buoyant body a1, a mooring rope a2, and an anchor a3 with a clamp member c, and an intake pipe opening b2 near the sea surface is taken offshore. The water is led to d1, and the deep water is pumped up and taken in by a water pump d2 on board.

[0003]

However, the above-mentioned conventional water intake apparatus has the following problems. <B> In the former water intake device, the length of the intake pipe reaches hundreds to thousands of meters because the intake pipe is laid from the coast to the bottom of the sea. Therefore, initial investment has been excessive, for example, the material cost of a long intake pipe increases the equipment cost. <B> Since the latter water intake device uses a wire or a chain for the mooring rope a2, it is very difficult to moor it in a deep water, and in some cases it cannot withstand waves and sinks. In addition, there is a problem that the mooring rope a2 is entangled with the intake pipe b1 under the influence of the waves and the ocean current, thereby obstructing the intake pipe b1. For this reason, mooring to a deep water site requires consideration of dynamic analysis and the like, and many problems to be solved remain.

[0004]

SUMMARY OF THE INVENTION The present invention has been conceived in view of the above-mentioned conventional problems, and has been developed in consideration of the above-mentioned conventional problems. The purpose is to provide.

Embodiments of the present invention will be described below with reference to the drawings.

<A> Overall Structure The water intake device 1 comprises an intake pipe 2, an anchor 3 installed below the intake pipe 2, an underwater float 5 provided on the way, and a water supply port 4 provided on the sea surface. In addition, the water intake device 1 can be provided with a rotary joint 6 in the middle of the water intake pipe 2. The water intake device 1 of the present invention is used for pumping deep water such as the sea and lakes.

<B> Intake Pipe The intake pipe 2 is made of a composite material containing a tension material such as fiber reinforced plastic. The diameter of the water intake pipe 2 formed in a cylindrical shape is preferably about 100 mm to 200 mm. An intake 21 is provided below the intake pipe 2, and deep water can be taken from the intake 21. The water intake 21 is preferably installed at a distance of 3 m to 5 m from the sea bottom so as not to suck in sediment on the sea bottom. Since deep water is taken from a depth of about 300 m below sea level,
The length of the intake pipe 2 is also about 300 m. Since the length of the intake pipe 2 is as long as about 300 m, the rotary joint 6 is attached in the middle of the intake pipe 2, and even if the intake pipe 2 is twisted under the influence of waves or ocean currents, the rotary joint 6 absorbs this twist. It is supposed to. In order to effectively absorb the twist of the intake pipe 2, it is preferable that the rotary joint 6 be mounted near the lower part of the underwater float 5.

<C> Anchor The anchor 3 is installed on the bottom of the water via the connector 7 below the water intake 21. The anchor 3 may be installed on the water floor as it is, or may be embedded and installed on the water floor. Anchor 3 includes intake pipe 2 and upper water supply port 4, underwater float 5
And a weight sufficient to moor a floating body (intake boat 10, pump 9 and the like) and the like. The connector 7 for connecting the anchor 3 and the water intake 21 has a flexible structure such as a rotary joint so that there is no problem even if the water intake pipe 2 is twisted or tilted under the influence of waves or ocean currents. ing. In the present invention, as described above, the anchor 3 has a sufficient weight, and the intake pipe 2 is made of a high-strength tension material.
It can also serve as a mooring material. As a result, wires and chains have conventionally been used as mooring members, but these can be omitted.

<D> Water supply port A water supply port 4 is attached to the upper end of the water intake pipe 2. Water inlet 4
Protrudes from the sea surface. A water supply hose 41 for water intake is attached to the water supply port 4. The water supply hose 41 is connected to the intake boat 1
0 pump 9 connected to the suction side. When taking water,
In order to prevent the intake vessel 10 from being damaged by the intake pipe 2 coming into contact with the intake pipe 2, a buffer material 22 is attached near the water supply port 4 above the intake pipe 2. In addition, it is preferable that a marker lamp 8 and the like be attached to the upper part of the water supply port 4 so that the installation location of the water intake device 1 can be determined from a distance.

<E> Underwater Float An underwater float 5 is provided above the water intake pipe 2. The underwater float 5 is, for example, formed in a hollow cylindrical shape and installed so as to be installed around the intake pipe 2. The underwater float 5 is a floating body for making the water supply port 4 protrude above the water. The underwater float 5 is disposed below the water surface so that the intake pipe 2 is not inclined by the influence of waves or ocean currents.

Next, a case in which deep water is taken out using the above-described water intake device 1 will be described.

<A> Installation of Water Intake Device The water intake pipe 2 having the anchor 3 and the water intake 21 attached to the tip is submerged in the water bottom. Note that a rotary joint 6 is attached to the water intake pipe 2 in the vicinity of the lower part of the underwater float 5 in advance. The underwater float 5 is installed from above the water pipe 2, and the water supply port 4 is connected to the water pipe 2.
Attach to the top. A sign lamp 8 is attached to the upper part of the water supply port 4. In this way, the water intake device 1 is installed on an arbitrary seabed, and preparation for taking in deep water is made. Since the indicator lamp 8 is attached to the upper part of the water supply port 4, the location of the installed water intake device 1 can be determined from a distance.

<B> Water intake by water intake device The water intake vessel 10 circulates toward the installed water intake device 1. The intake boat 10 can easily approach the sign light 8. The water supply hose 41 above the water supply port 4 is connected to the suction side of the water pump 9 of the water intake boat 10 moored offshore. When the water supply hose 41 and the water pump 9 are connected, even if the water intake boat 10 comes into contact with the water intake pipe 2, the buffer material 22 is attached, so that the water intake pipe 2 is not damaged. The pump 9 is operated to pump deep water from the water intake 21. The deep water is taken in from the water supply port 4 through the water supply pipe 4 through the water supply hose 41 and the water pump 9 and stored in the water storage tank (not shown) of the water intake boat 10. Since the intake 21 is connected to the anchor 3, it does not move from the bottom of the water,
Deep water at a predetermined water bottom can be taken. In addition, since the rotary joint 6 is attached in the middle of the intake pipe 2, even if the intake pipe 2 fluctuates under the influence of waves or ocean currents, the rotary joint 6 absorbs this fluctuation and takes in deep water without any problem. be able to. Depth of deep water taken as above 1
By transporting by sea at 0 and transporting it to a tank on land, it is possible to meet various demands. Intake boat 10 again
It circulates to the intake device 1 and takes in deep water.

In the present invention, in order to prevent the water intake pipe 2 and the mooring material from being entangled in the deep sea, the water intake pipe 2 is a simple deep water water intake system which also serves as a mooring material, and the water intake amount is 50 to 500 tons / day. Ideal for use in relatively small cases, on the order of tons. At present, the demand for deep water is very large, but in many cases, when the cost is high as in the case of a submarine pipe system, supply cannot be stopped. According to the water intake device 1 of the present invention, it is possible to take in deep water at low cost, and it is possible to anticipate many demands. A major feature of the present invention is that the water pipe 2 substitutes a mooring material for mooring a floating body such as the lift pump 9 and the intake boat 10 in which the pump is installed as described above. For this reason, the wires and chains used as the mooring material can be omitted, and the mooring rope is not entangled with the water intake pipe 2 under the influence of waves and sea currents as in the related art, which hinders water intake. Not at all.

[0016]

According to the deep water intake apparatus of the present invention, the following effects can be obtained. <B> Anchor is installed at the lower part of the intake pipe and the intake pipe is installed vertically from the seabed, so there is no need for long intake pipes such as laying the intake pipe along the seabed from the coast, and material costs are reduced. It is cheap and does not increase equipment costs. <B> Since the intake pipe is made of a tension material and an anchor is installed below the intake pipe to replace the mooring material with the intake pipe, there is no need to use a mooring rope such as a wire or a chain. Therefore, there is no problem such as the mooring rope being entangled with the intake pipe under the influence of the waves and the ocean current, thereby obstructing the intake. <C> Since there is no need to use mooring ropes such as wires and chains, it is possible to easily install a water intake device in a deep water.
