RU2555904C2 - Floating means with inflatable balloons - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: invention relates to ship building, particularly, to floating means with flotation ability based on inflatable balloons. Proposed floating means consists of inflatable balloons, frame above the latter, means to fasten said balloons to said frame and means of protection of said balloons against damages. Said protection means are composed of removable jacket of elastic material. Said fastening means are composed by resilient rings made from material of conveyor belt type. Resilient ring diameter is smaller than as-inflated balloon diameter. Inflatable balloon consists of several tight sections. Air hoses for inflation of balloons and air release therefrom are arranged inside the balloon and brought outward through its front end.

EFFECT: protection of inflatable balloons in use.

Description

The present invention relates to the field of shipbuilding, namely to watercraft, the buoyancy of which is provided by inflatable balloons.

The geophysical catamaran according to the patent of the Russian Federation No. 2466052, containing inflatable balloons, a frame located above the inflatable balloons and means for securing the cylinders to the frame is known from the prior art. The disadvantage of this catamaran is the lack of protection of the cylinders from punctures, cuts and abrasion. There are quite a few proposals for the protection of inflatable boats. In the utility model patent of 2005102648/22, the protection of the cylinders is ensured by the fact that they are placed inside a common soft shell stretched over the frame. The disadvantage of this method is the large size and weight of the shell with any significant size of the craft. In the patent on application 2010127122/11, this problem is solved by placing additional smaller floats below the inflatable balloons. However, this does not save the side surfaces of inflatable balloons from damage.

The closest technical solution to the proposed invention is the placement of an inflatable balloon in a protective sheath, as proposed in the patent for application No. 2012103738/11 (prototype). According to this patent, a layer of an elastomeric material such as polyurethane is applied to the balloon. However, in order for this layer to be strong, reliable, and fulfill its functions, an appropriate technology for its application must be ensured, commensurate in complexity with the technology for manufacturing the fabric of the balloon itself. This is a disadvantage of the technical solution for application No. 2012103738/11. It is simpler and better for a protective shell to use ready-made material with the right properties to get a camera-tire type result.

The aim of the invention is to eliminate this drawback. This goal is achieved by the fact that in a watercraft consisting of inflatable balloons, a frame above the inflatable balloons, devices for attaching the inflatable balloons to the frame and means of protecting the inflatable balloons from damage, the means of protecting the inflatable balloon is made in the form of a removable cover made of elastic material. If there are covers on the cylinders, it is convenient to attach them to the frame in the form of flexible rings made of a material such as a conveyor belt, while the inner diameter of the ring is less than the diameter of the balloon when inflated. It is advisable to make each cylinder for reliability from several airtight compartments, while air hoses for pumping and bleeding air from each compartment, for the purpose of ease of maintenance, are located inside the cylinder and out through its front end. In order to evenly distribute the load from the frame to the cylinders, boards can be longitudinally fixed on the upper generatrix of the covers along the arc, and arches are made on the frame to which flexible rings for fastening the cylinders are attached, while in the assembled state, the boards are located under these arches.

Technical description

Arches 2 are fixed on the frame 1 (Fig. 1), to which the flexible rings 3 are attached, inflatable balloons 4 are placed inside the flexible rings in the covers. Boards 5 are longitudinally installed between the cover and the ring in the arch. Air hoses 7 (FIG. 2) are brought to the front end of the cylinder 6 for pumping and bleeding air from the airtight compartments of the cylinder. In the working position, the hoses 7 are placed under the petals of the cover 8, which are tied with a cord 9 (figure 1) or laced. To drag the balloon in a deflated state into the cover, use the rope 10 (Fig. 3), passed through an opening in the rear end of the cover 8.

Operating principle

When preparing the watercraft for launching into the covers 8 using the ropes 10 they drag the cylinders 6. The cylinders in the covers with the boards are evenly placed on the frame 1 in the rings 3, after which the cylinders 6 are pumped up. Under the influence of the air pressure the cylinders 6 with the covers 8 and the boards 5 the rings 3 are bursting and pressed against them. This ensures reliable fixation of the cylinders with covers and boards relative to the frame. If necessary, the cord 9 is untied, the petals of the cover 8 are opened, the hoses 8 are removed, the air is blown out of the container, after which it is removed from the cover 8, while the rope 10 remains in the cover and its end protrudes from the hole in the rear end of the cover. The rope 10 is untied from the balloon being replaced and tied to a new one, which is pulled into the cover by the rope 10, and then inflated. All this can be done from the deck of the craft without lifting it from the water.
