Description

The water intake provided on the bottom of the ship is attached with its shape determined according to the performance of each ship, but the present invention relates to the water intake.

Conventional intakes on the bottom of the ship have been installed by selecting a fixed shape such as high-speed, medium or low-speed, depending on the ship's operating speed.

From here, FIG. 5, FIG. 6, FIG. 7 will explain typical water intakes provided on the bottom of the ship. Fig. 5 is attached for medium and low speeds, and the strainer section 1 has several round holes or several lattice holes that are inclined from the foreground to the back to prevent inhalation of dust. It is useful to make it easy to suck up.
6 is attached for high speed, and the strainer section 1 has several lattice holes and has a slope from the front to the rear as in FIG. 5, and the end of the rear slope is different from the strainer section in FIG. A spoon-shaped receptacle has been devised so that the power of water during high-speed navigation works in the direction of suction. This type of strainer can be removed for the middle and low speeds, and the strainer can be removed. This type of strainer is intended to clean the shells and algae attached to the water intake and the strainer by removing the strainer. The bolts for attaching the bolts are mounted so that the heads of the bolts are along the strainer surface by sinking the flat bolts 2 into the strainer mounting holes with the countersunk so that they do not receive water resistance. However, it is difficult to prevent the bolts from rotating.

At the intakes described above, each ship had to select and install a suitable fitting for the ship from all shapes of intakes in order to maintain the suction efficiency of the intake provided at the bottom of the ship due to the difference in operating speed.

The present invention is intended to solve the problems of such a conventional configuration, and eliminates the hassle of having to select and install intakes according to the operating speed of each ship. The purpose is to respond to changes in specifications to improve ship performance.

And, in order to achieve the above object, the present invention arranges several fins provided in parallel to the traveling direction in order to catch the water escaping from the intake port to the left and right with respect to the ship traveling direction on the inclined surface of the intake strainer section. In front of the front and rear fins, rounds R2 to R200 that have the same function as the inclination of 10 ° to 80 ° with respect to the straight line of the strainer circle, in order to collect fresh water and debris floating in seawater when navigating the ship. Is provided.

In order to catch the water that has escaped to the strainer and the lower part of the water intake, a water flow guide plate with a flap (hereinafter referred to as a water collecting plate) that is attached to the front fin of the strainer is provided. Bend it so that the force of water works in the direction of sucking up, or if it is still bad at sucking up during operation, move the water collecting plate to the rear fin.

Medium and low speed ships shall be used without bending the flaps of the water collecting plate. If the suction is sufficient even if the water collecting plate is removed, the water collecting plate should be removed to reduce the resistance of the ship. I will do it.

As described above, the present invention eliminates the troublesomeness that the user has to select and install the intake port according to the operation speed of the ship because the user can easily adjust the amount of suction of the intake port. The performance corresponding to the change of the specification by the performance improvement of the ship can be provided.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, an embodiment of the present invention will be described with reference to FIG.

In the figure, the water intake main body 12 is fixed to the hull 13 by the hull fixing conical plate 10 and the hull fixing nut 11.
The screw portion of the water inlet main body 12 into which the hull fixing nut 11 is inserted is basically a pipe parallel screw, but when the screw of the water stop valve to be attached to the screw uses a pipe taper screw, the water inlet main body Cut the taper screw for the pipe according to the effective screw depth of the taper screw for the water stop valve from the screw part entrance.
And 1 attaches the strainer 2 which prevents rough garbage here in the opening part of the intake main body with the inclination 2 degrees-20 degrees to make it easy to suck in fresh water and seawater at the time of navigation.
There are several front fins 4 and rear fins 5 on the hull mounting surface 3 of the strainer 2 so that the water collecting plate 6 can be fixed on both the front and rear sides.
Both fins 4 and 5 are provided with an inclination of 10 ° to 80 ° in order to carry away floating dust during navigation with reference to the circular straight line from the base of the front fin. The same applies to roundness R2 to R200.
The gap and height between the fork fins and between the front fin 4 and the rear fin 5 are easy to peel off when dust such as floating vinyl sticks to the water intake, and prevents the intake from being completely sealed.
Next, the water collecting plate 6 is attached to the front fin 4 or the rear fin 5 so that the force of the water to escape to the lower portion of the intake port during navigation is applied in the suction direction of the intake port. If you attach it to 5, the power of the water at the time of navigation is stronger and it works in the direction of sucking up the intake, so you can see the adjustment and put it on the fin 4 or 5
The water collecting plate 6 is passed through the groove of the strainer 2 and the bending margin for mounting the water collecting plate 6 protruding from the back side of the strainer is bent inward to adjust the water flow guide after fixing the fixed water collecting plate 6 by bending the flap 7. adjust,
At this time, the water collecting plate 6 helps to prevent the strainer 2 from sucking dust and completely closing the intake port during navigation.
Then, the strainer 2 and the intake body are fixed as follows using a spring washer 8 and a hexagon socket button bolt 9.
The bolt hole of the strainer 2 to be fixed to the intake body 12 is provided with a counterbore which is 0 to 10 mm larger than the outer diameter of the spring washer 8 and 0 to 3 mm deeper than the thickness of the washer 8 in order to sink the thickness of the spring washer 8.
The hexagon socket button bolt 9 used for tightening comes out of the strainer surface when tightened, but the truss head bolt and this hexagon socket button bolt 9 are streamlined with the head turned upside down and thinned. So even if the thickness of the head protrudes from the strainer surface, there is little resistance to water flow and it will not catch dust,
The range of the bolt head protruding from the strainer surface is from the strainer surface to the bolt head thickness.
And since the mounting surface of the head of this bolt is flat and can use a spring washer, the force of bolt loosening prevention due to vibration of the ship can be stronger than that using ordinary flat head bolts,
Generally, the thickness of the strainer is made thin, but by making use of the advantages of this bolt, it is possible to secure a large thickness of the bolt mounting portion of the strainer 2.
Screw the hexagon socket button bolt 9 through the spring washer 8 into the strainer 2 mounting screw hole at the opening of the water inlet, fix the strainer 2, apply silicon to the bolt for further rotation prevention, and tighten the bolt a little. However, in order to suppress the resistance of the water flow, silicon is also poured along the surface of the strainer 2 that sinks the thickness of the spring washer to reduce the resistance of the water flow.
As described above, an embodiment in which the strainer 2 at the intake body opening is formed so that it can be attached and detached and the strainer can be changed between a high-speed ship and a medium / low-speed ship.
