JPS581325Y2 - Telescopic water tower - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an improvement of a telescopic water tower.

Water towers for fire boats, etc. are required to have the ability to expand and contract.

Therefore, the conventional structure was as shown in FIG.

01 is a mast, 02 is an inner cylinder, 03 is an outer cylinder that slides on the outer circumference of the inner cylinder 02, 04 is a water cannon attached to the tip of the outer cylinder,
05 is a pulley attached to the mast 01, 06 is a winch, 07 has one end locked to the lower end of the outer cylinder 03, and the pulley 05
Guided by the mast 01, the other end is guided by the winch 06.
When a cable 07 guided by a pulley 05 is wound in and unwound by a winch 06, an outer cylinder 03 equipped with a water cannon 04 at the top expands and contracts up and down the outer periphery of the inner cylinder 02.

(1) Because lifting cables, pulleys, etc. are installed within the cramped mast structure, installing and adjusting them is extremely troublesome.

(2) During use, when the outer cylinder is stretched, the outer cylinder itself absorbs the reaction force due to water spray and the inertia force due to hull vibration and rolling (particularly the large inertia force in the direction of tilting toward the side of the ship due to hull rolling). However, it is necessary to increase the strength by increasing the diameter of the outer cylinder, which results in an increase in the weight of the telescopic part.

There was a drawback.

The present invention eliminates the above-mentioned drawbacks of the conventional technology, and an embodiment thereof is shown in FIGS. 2 and 3.

1 is the hull, and 2 is an outer cylinder whose lower end is fixed to the hull 1.

Reference numeral 3 denotes an inner cylinder, which is slidably fitted into the outer cylinder 2 and has a top plate 4 at its upper part.

A water tower 5 is attached to the top plate 4 of the inner cylinder 3.

Reference numerals 6 and 7 designate an upper boom and a lower boom, which are provided in plural sets and both are pivotally connected by a hinge 8 and configured to be able to bend outward. The lower end of the boom 7 is pivotally attached to the base of the outer cylinder 2 or the hull 1.

9 is a pulley attached to the outer cylinder 2, 10 is a winch attached to the hull 1, and 11 is a cable, one end of which is locked to the hinge 8, and the other end is guided to the winch 10 via the pulley 9. The operating cable 12 is a gasket that prevents rainwater from entering through the sliding parts of the outer cylinder 2 and inner cylinder 3.

Note that two or four sets of the upper boom 6 and lower boom 7 are provided, but in the case of two sets as in the embodiment, it is preferable to install them toward the side of the ship so as to support the inertia generated by the hull rolling. .

Next, to describe the operation of the present invention, when the winch 10 winds in and unwinds the cable 11, the upper boom 6 and lower boom 7, which are connected to the cable 11 via the pulley 9, bend and extend, and the water cannon 5 is activated. The inner cylinder 3 installed at the top expands and contracts inside the outer cylinder 2.

As described above, the present invention consists of an outer cylinder fixed vertically to the hull, an inner cylinder slidably fitted into the outer cylinder, a water cannon mounted on the top of the inner cylinder, and a joint between the inner cylinder and the outer cylinder. Multiple sets are set up around the area,
A boom whose upper end is pivoted near the top of the inner cylinder, whose lower end is pivoted to the base of the outer cylinder or to the ship's hull, and whose middle part can be bent outward with a hinge; one end is locked to the hinge part of the boom. Since it is a telescopic water tower, the other end consists of an operating cable guided to a winch on the ship via a pulley attached to the outer cylinder. By equipping
Their installation and adjustment work becomes easier.

(2) During use (extended state), the inner cylinder is supported by the boom, which is advantageous in terms of strength.

It has excellent effects such as
