Description

  The present invention relates to a deep water intake device that lowers a water intake pipe from a floating body floated on a water surface into the sea and takes in seawater from a water intake provided in the water intake pipe.

  Deep water is seawater that exists in the deep sea with a depth of 200 m or more near the shelf, and is characterized by abundant organic nutrients and clean, low-temperature properties. For this reason, use in the food field, fishery field, pharmaceutical field, industrial field and the like is being promoted. For deep water intake, changing the point where the ship collects the deep water, lowering the intake pipe from the ship to the sea and taking the deep water, or a permanent facility for taking the water from the land without changing the sampling point. There is a way to install and take water.

Next, a conventional method for taking deep water from the ship will be described with reference to FIG.
FIG. 8 shows a case where the hull 21 for taking deep water is towed to the sampling position by the power ship 22. The hull 21 is provided with an electric winding device 23. This winding device 23 rotates and drives a reel 24 by electric force to wind and feed out a nylon (having flexibility) water intake tube 25.

  By the way, since it is necessary to change the point from which deep water is collected, it is necessary to easily take up and draw out the intake pipe 25. Therefore, in the conventional method of taking deep water from the ship, a flexible nylon material is used as the material of the intake pipe 25.

  However, when the intake pipe 25 made of nylon is used, there is a problem that the flexibility is adversely affected and the intake port cannot be lowered directly to the sampling position at a depth of 200 m or more due to the influence of the tide or the like. Therefore, it is necessary to install the guide member for preventing the bending of the water intake pipe 25, and it is difficult to draw out and install the intake pipe 25.

  The present invention has been made to solve such problems, and it is easy to feed and install the intake pipe without requiring a guide member for preventing bending, and also to take up the intake pipe. It is to provide an easy deep water intake device.

The present invention employs the following means in order to solve the aforementioned problems.
That is, the deep water intake apparatus of the present invention includes a floating body floated on the water surface, a water intake pipe mainly composed of a plastic pipe lowered from the floating body into the sea, and a water intake provided at the tip of the water intake pipe. A pump for sucking and pumping seawater taken from the water intake through the intake pipe to the floating body side, a tank for storing seawater taken in via the pump, and a drive mechanism for connecting the intake pipe to the drum side A hose reel that can be fed out or rolled up to the drum side, and a pressing roller that rotatably presses the water intake pipe wound up by the hose reel toward the drum side.

  The intake pipe uses a hard polyethylene pipe as a plastic pipe. Since this polyethylene pipe is self-supporting with little bending due to the influence of tidal currents or the like, the water intake can be lowered directly to a sampling position at a depth of 200 m or more.

  By providing the hose reel with a pressing roller that rotatably presses the water intake tube against the drum, the repulsive force generated when the hard polyethylene tube is wound is suppressed to facilitate the winding operation. Further, since the pressing roller can suppress the repulsive force of the polyethylene pipe even during the feeding, the feeding operation can be facilitated.

  Further, in the deep water intake apparatus of the present invention, the pump and the pressing roller are integrally attached to the hose reel, and the pump, the pressing roller, and the hose reel are configured in a unit form. It is characterized by. Furthermore, the pump, the pressing roller, and the hose reel configured in a unit form are fixed to the floating body via a wire and a lever block.

  Since the pump, the pressing roller, and the hose reel are configured as a unit, it is easy to carry in to the ship, and the installation work only needs to be fixed with the hull, wire, and lever block.

  According to the present invention, it is possible to provide a deep water intake device that does not require a guide member for prevention of bending and breakage reinforcement, and that facilitates the take-out operation and installation work of the intake pipe and also facilitates the take-up operation of the intake pipe. Can do.

The best mode for carrying out the present invention will be exemplarily described in detail below with reference to the drawings.
[Configuration of deep water intake system]
That is, as shown in FIGS. 1 to 3, the deep water intake apparatus of the present invention is a water intake pipe 2 mainly composed of a floating body 1 floated on the water surface and a plastic pipe lowered from the floating body 1 into the sea. And a water intake 3 provided at the tip of the water intake pipe 2, a pump 4 that sucks seawater taken from the water intake 3 into the floating body 1 through the water pipe 2, and pumps seawater taken in via the pump 4. A tank 8 to be stored, a hose reel 5 that can draw out the intake pipe 2 from the drum 5a side by the drive mechanism 6 or roll it up to the drum 5a side, and an intake pipe 2 wound up by the hose reel 5 to the drum 5a. And a pressing roller 7 that presses to the side in a rotatable manner.

  Although the hull as the floating body 1 is described as a power ship in this embodiment, it may be towed by a power ship without having its own power.

  The intake pipe 2 uses a hard polyethylene pipe as a plastic pipe. Since this polyethylene pipe is self-supporting with little bending due to the influence of tidal currents or the like, the water intake can be lowered directly to a sampling position at a depth of 200 m or more.

  In the deep water intake apparatus of this embodiment, as shown in FIGS. 6 and 7, the pump 4 and the pressing roller 7 are integrally attached to the hose reel 5, and the pump 4, the pressing roller 7, the hose reel 5, Is configured in unit form.

That is, in the hose reel 5, the drum 5a and the reel are rotatably supported by the bearings on the suspension frame. Then, the cylindrical drum 5a and the two disk-shaped reels sandwiching the drum 5a are electrically forward-rotated (feeded out) and reversed (wound-in) by the drive mechanism 6. The intake pipe 2 is wound around the drum 5a sandwiched between two reels in the order of the first layer to the second layer in the reverse (winding) operation. Further, the end of the water intake pipe 2 is connected to a deep water intake provided in the hose reel 5.

  The pump 4 is installed on a suspension base of the hose reel 5. The water absorption side of the pump 4 is connected to a deep water intake provided in the hose reel 5 via a hose. On the other hand, the water discharge side of the pump 4 is connected to the tank 8 via the food hose 9.

  The pressing roller 7 is located between the reels, and a shaft portion that swings the pressing roller 7 is installed on a suspension base of the hose reel 5. And it is comprised so that a roller may press toward the drum 5a side. This pressing force presses the water intake pipe 2 with a roller so that the water intake pipe 2 does not become turbulent when the water intake pipe 2 is wound around the drum 5a. This pressing force is configured to be different (so that the force becomes weak) every time the number of layers around which the intake pipe 2 is wound around the drum 5a increases. In other words, step by step each time you transfer from the first layer to the second layer, the second layer to the third layer, the third layer to the fourth layer, the fourth layer to the fifth layer, the fifth layer to the sixth layer, etc. It is configured to gradually weaken. Thus, the pressing roller 7 suppresses the repulsive force generated when the hard polyethylene pipe is wound, thereby facilitating the winding operation. Further, since the pressing roller 7 can suppress the repulsive force of the polyethylene pipe even during the feeding, the feeding operation can be facilitated.

  The suspension base of the hose reel 5 is configured to be fixed to the floating body 1 via a wire and a lever block 10.

  At the bow of the floating body 1, a hose guide 11 is provided on a roller for unloading a fish net (diameter: about 350 mm). As shown in FIGS. 2 to 4, the hose guide 11 is fixed by pressing a support ring on the roller against the floor surface. The distance between the ring and the hose guide 11 is adjusted with a stud bolt nut.

[Installation procedure of deep water intake system]
Next, the installation procedure of the deep water intake apparatus will be described with reference to FIGS.
First, a wire is hung on the hook of the crane, a shackle is hung on the tip of the wire, and the hanger reel 5 is attached to a suspension ring (four locations) on the upper surface of the suspension frame.

  Attach the shackle to the suspension ring (4 locations) on the bottom of the suspension base and pass the wire through. Moreover, a shackle is attached to the suspension ring of the main body frame of the hose reel 5, and the opposite side of the wire is attached.

When lifting, confirm that the main body frame of the hose reel 5 is horizontal.
The crane is transported to a predetermined position on the ship by a crane, and the hose reel 5 is lowered on a laying board laid on the floor of the ship.

  Remove the crane wire from the suspension base, pass the 1 m wire through the shackle of the hanger reel 5 main body frame, and hang the lever block 10 on the opposite side.

  In addition, it is folded in half through a 1 meter wire at the angle of the ship's edge. It should be noted that a rubber plate is sandwiched where the wire hits the angle so that the wire is not bent.

  Then, the end of the wire is hung on the lever block, the four corners of the frame are drawn and drawn with the lever block, and fixed so that the main body of the hose reel 5 does not move. At that time, the wire hung on the hose reel 5 main body from the angle of the ship edge is set at an angle of 45 ° with respect to the center line of the ship (see FIG. 3).

  As described above, since the pump 4, the pressing roller 7, and the hose reel 5 are configured as a unit, the carrying-in operation onto the ship is easy, and the installation operation only needs to be fixed by the hull, the wire, and the lever block 10.

[Feeding work procedure of intake pipe 2]
Next, the delivery work procedure of the intake pipe 2 will be described.
One worker has the tip of the intake pipe 2 and the operator of the hose reel 5 presses the intake pipe 2 “feed” button of the operation panel 12 as shown in FIG. Then, since the intake pipe 2 is drawn out from the hose reel 5, an operator having the tip of the intake pipe 2 pulls the tip to the hose guide 11. When the tip of the intake pipe 2 reaches the fish net unrolling roller of the hose guide 11, once the intake pipe 2 is stopped, the tip of the intake pipe 2 passes under the fish net unwinding roller. Install the water intake 3. In addition, a weight or depth meter of about 80 kg is attached to the tip of the intake pipe 2.

First, the driver presses the “Feed” button again in a state where the weight is inserted and the intake pipe 2 is under tension. Then, the intake pipe 2 is drawn out into the sea.
The intake pipe 2 is drawn out into the sea until the entire intake pipe 2 is drawn out, so that no waste winding is left on the drum 5a side.

[Deep ocean water intake work procedure]
Next, the deep sea water intake operation procedure will be described.
The suction side hose of the pump 4 is connected to the deep water outlet of the hose reel 5. When the driver presses the pump “ON” button on the operation panel 12 as shown in FIG. 5, the pump 4 is activated and deep water is taken in via the intake pipe 2. The taken deep water is stored in the tank 8 through the food hose 9.

  When the predetermined amount of deep water has been stored in the tank 8, the driver presses the pump “OFF” button on the operation panel 12.

[Involvement procedure of intake pipe 2]
Next, a procedure for entraining the intake pipe 2 will be described.
As shown in FIG. 5, the driver of the hose reel 5 presses the intake pipe 2 “roll” button of the operation panel 12. Then, the intake pipe 2 is wound around the drum 5a. At this time, the intake pipe 2 is wound in order from the end of the drum 5a.

  When the first layer of the drum 5a is wound, and the second layer is transferred, the pressing roller 7 is once removed from the water pipe 2, and the pressing force of the pressing roller 7 is reduced, and then the second layer is wound. The same operation is repeated when transferring from the second layer to the third layer, the third layer to the fourth layer, the fourth layer to the fifth layer, and the fifth layer to the sixth layer.

  When the tip of the intake pipe 2 is pulled up from the sea to the hose guide 11, the driver presses the “stop” button of the intake pipe 2 on the operation panel 12, temporarily stops the winding operation of the hose reel 5, and the intake pipe 2. After removing the water intake 3, the weight, and the depth meter from the front end of the head, the winding operation of the hose reel 5 is resumed, the entire intake pipe 2 is wound around the drum 5a, and the winding operation of the intake pipe 2 is completed.
