Description

[Detailed Description of the Invention] The present invention relates to a water intake facility that takes water from a dam, lake, swamp, etc. and sends it to a urine treatment plant or the like.

Conventionally, when water is taken from a dam or lake, the water is generally pumped up using a pump using a fixed intake pipe installed on the shore of the dam or lake, but such water intake methods depend on various water intake conditions. cannot be satisfied.

In other words, in actual water intake, there are strict conditions that vary depending on the purpose of use of the water, such as the lower the water intake temperature is, the better, the water temperature being constant and not changing much, and the fact that soil and garbage must never be mixed in. It is usually imposed.

However, the above-mentioned conventional water intake equipment cannot meet the above temperature conditions because it cannot respond to changes in water level due to seasonal changes or rainfall, etc. Moreover, the water intake is opened near the shore. , it is easy to suck in dirt and dust, and the requirements in this aspect cannot be met.

The present invention was developed in view of the above, and aims to provide a water intake facility that can take stable water at a low temperature regardless of water level fluctuations, weather, etc., without contaminating garbage or soil. purpose.

The present invention will be explained in detail below based on the drawings.

FIG. 1 shows the overall configuration of the water intake equipment according to the present invention, where 1 is a floating platform and 2 is a water intake hose.

This water intake hose 2 has one end connected to a submersible water intake pump 4 provided in the water intake part 3 of the floating platform 1, and the other end connected to a water intake pipe 5 provided on land, and the intermediate portion is connected to a required number of The buoy 6 is suspended below a certain water surface to constitute the water intake equipment of the present invention.

Figures 2 and 3 show an embodiment of the floating platform 1, and the floating platform 1 shown in these figures has a large number (of The frame body 7 is constructed by attaching 11 buoyant bodies 8, and obtains buoyancy from the buoyant bodies to float the frame 7 on the water surface.

The box-shaped water collection section 3 that can be submerged in water is provided in the center of the floating platform 1, and the bottom of the floating platform 1 is equipped with an auxiliary boat for carrying workers when replacing the water intake pump 4 or during regular inspections. A berthing section 9 (not shown) is provided in a cut-out state on which a water tank (not shown) is placed horizontally, and a pedestal 10 is installed between the water intake section 3 and the berthing section 9 from the berth section 9 to the water intake section 3. (omitted in FIG. 2).

This pedestal 10 supports the equipment installed in the water intake section 3, and in this embodiment, the water intake pump 4 is suspended from the water intake section 3 by a wire 11 so as to be vertically movable.

A net 12 made of expanded metal or the like is stretched on the bottom surface of the water intake section 3, and a net 13 is stretched over the water surface to prevent dust from being sucked in.

On the other hand, so that workers can walk on the frame 7, floorboards 14 are placed on both left and right outside of the part of the frame 7 where the water intake part 3 is vertically installed, and a net made of expanded metal or the like is installed. body 15
is attached to the apex (front) portion of the frame 7.

The water intake hose 2a connected to the water intake pipe 5 and the water intake hose 2b connected to the water intake pump 4 are connected to each other by a pipe joint 16 on the mesh body 15, and are connected to a control panel (not shown) on land. The underwater cable 17a connected to the water intake pump 4 and the underwater cable 17b connected to the water intake pump 4 are also connected to each other via the waterproof connection surface 18 installed on the net 15 in the same manner as described above.

As will be described later, the underwater cable 17 is wired along with the water intake hose 2.

Anchors 19 are attached to the apex portions of the frame 7 located on the left and right sides of the berthing section 9, and are structured to anchor the floating platform 1 and prevent its free movement.

20 is a cross beam fixed to the upper part of the frame 10 and suspending the water intake pump 4 by a wire 11, and 23 in FIG. 1 is a check valve.

In the illustrated embodiment, the buoy 6 and the buoyant body 8 are made of a synthetic resin bag filled with a foam material having a closed cell structure.

With this structure, unlike hollow drum cans, it will not corrode, and even if the bag has a hole, it will not sink or lose its buoyancy, so it is preferable, but buoys or buoyancy bodies of other structures may be used. You can also do that.

Furthermore, in the figure, the water intake pump 4 is installed in the water intake part 3 of the floating platform 1, but it is also possible to install it on land, etc., and open the water intake hose 2 to the water intake part 3. .

FIG. 4 shows an example of how the water intake hose 2 is suspended by the buoy 6. The buoy 6 is connected to the water intake hose 2 by the wire 21.
is suspended below the surface of the water.

A reinforcing wire 22 is suspended slightly above the water intake hose 2 along with the water intake hose 2, and an underwater cable 17 such as a cabtyre cable is mounted above the reinforcing wire 22 at a distance from this wire. It is suspended.

The reinforcing wire 22 reinforces the water intake hose 2 and the underwater cable 17, which are weak against tensile force, and works together with the anchors 19 to anchor the floating platform 1.

By the way, in the water intake equipment shown in the figure, the installation depth of the water intake pump 4 is 4 m, and the hanging depth of the water intake hose 2 is 1 m.

The length of the underwater cable 17 is set to about 60 cm.

Therefore, when the water intake pump 4 operates, water that is constant in temperature, cool, and does not contain dirt or sediment is pumped out through the water intake hose 2.Also, even if there is driftwood, the submersible cable 17 and the water intake hose 2 come into contact with it. It will not be damaged or damaged.

However, the depth of the water intake pump 4, water intake hose 2, etc., particularly the water suction depth of the water intake pump 4, is not limited to the above, but can be arbitrarily adjusted in consideration of the purpose of water intake, environmental conditions, etc.

Needless to say, the floating platform 1 moves up and down following the rise and fall of the water level.

The water intake equipment according to the present invention has the above-mentioned configuration, and operates the control panel installed on land to operate the water intake pump 4, pumps out water through the water intake hose 2, and transports it through the water intake pipe 5 to a human waste treatment plant, etc. The floating platform 1 moves up and down in accordance with water level fluctuations (see the two-dot chain line in Figure 1).
Necessary water can be pumped up smoothly regardless of changes in water volume due to rainfall, drought, etc. Moreover, since the water intake pump 4 pumps water from a predetermined position below the water surface, the water temperature remains constant and does not contain garbage or sediment. No water can be taken out.

In addition, since the water intake hose 2 is suspended below the water surface,
Even if there is floating matter such as running water, it will not be damaged by touching it.

Furthermore, a berthing part is cut out in the rear part of the frame whose front part is moored with reinforcing wire, so it is easy to attach the reinforcing ship to the floating platform, and at this time, the screw of the auxiliary ship can be attached to the reinforcing wire. It will not get caught on wires or water intake hoses.

Furthermore, there is a pedestal erected from the berthing section to the water intake section, which can be used to hold on to, making it easy and safe for workers to transfer from the auxiliary boat to the floating platform, or from the floating platform to the ship. It has the advantage of being able to work safely on a floating platform.
