Embodiment Construction

[0027]A leak preventing device 1 according to an embodiment of the present invention is schematically illustrated in FIGS. 1-4. The leak preventing device 1 is to be used with a tank 2 for transporting and / or storing liquid in order to prevent liquid from leaking out of the tank through a hole or crack in a wall of the tank below the surface 3 of the liquid in the tank if the tank is damaged due to an accident or wear. Thus, the leak preventing device 1 is to be pre-mounted to the tank 2 so as to be ready for use in a possible situation when the tank is damaged and liquid starts to leak out of the tank.

[0028]The leak preventing device 1 comprises a floating body 4 which is configured to have such a buoyancy that it is capable of floating at the surface 3 of the liquid in the tank 2 with at least an upper part of the floating body 4 located above the surface 3 of the liquid in the tank. The leak preventing device 1 also comprises a flexible hose 5 with a first end 6a and an opposite ...

Abstract

A leak preventing device (1) for preventing liquid from leaking out of a damaged tank (2), the device comprising:—a floating body (4) capable of floating at the surface (3) of the liquid in the tank; and—a flexible hose (5), the first end of the hose being fixed to the floating body and the hose being fixed to a wall of the tank at a point of attachment (8) at a distance from said first end, wherein the hose extends freely inside the tank between the floating body and said point of attachment and wherein the second end of the hose is connectable to a suction side of a vacuum pump(9) so as to allow gas to be drawn off via the hose from a gas-filled space (10) in the tank above the surface of the liquid in order to produce an under pressure in said space. The invention also relates to a tank for transporting liquid provided with such a device.

Description

FIELD OF THE INVENTION AND PRIOR ART[0001]The present invention relates to a leak preventing device according to the preamble of claim 1 for preventing liquid from leaking out of a damaged tank. The invention also relates to a tank for transporting liquid provided with such a device.[0002]Liquid fuel and other types of liquids may be transported and stored in tanks of various types. If such a tank is damaged, for instance due to an accident or wear, the liquid in the tank may leak to the surrounding environment, which may cause a lot of problem, for instance in the form of material damages, environmental pollution and health and safety hazards for people in the vicinity of the leaking tank. It is previously known, for instance from GB 1 020 581 A and DE 1 525 465 B, that liquid may be prevented from leaking out through a leak below the surface of the liquid in a tank by producing a sufficient underpressure in a gas-filled space above the surface of the liquid in the tank by means of...
