Description

BACKGROUND

1. Technical Field

The present invention relates to an automated boats washing dock.

In particular, the present invention relates to an automated boats washing dock of the type carrying out the complete boats washing directly into the sea.

The present invention relates also to a method for boats washing in the automated boats washing dock.

2. Description of the Related Art

As is well known, in the field of crafts, the cleaning of the boat's submerged part, the so-called “hull”, is of great importance. Indeed, since the boat is put in the sea, a thin layer of vegetation begins to form on the bottom of the boat itself. This layer, consisting of bacteria, microorganisms, protozoa, and macro algae, tends to consolidate more and more, favoring the formation of small deposits that become very difficult to remove. The growth of these organisms leads to an appreciable decrease in the performance of the boat and, consequently, to a higher consumption of energy resources necessary for its thrust, as well as a slow and continuous deterioration of the hull.

The known solutions to solve this problem involve the treatment of the hull with poisonous chemicals, the so-called “anti-fouling”, which, however, only slow down, without eliminating, the proliferation of organisms and micro-organisms, flora and fauna that contact the hull. Moreover, the treatment is repeated once a year or every two years and requires a complex series of operations, such as:—haulage, which consists in the extraction of the boat from the water;—potting and pressure washing, through which the boat is dry placed;—The dock, which consists in the cleaning of the hull;—The launch, or the boat laying in the water. Therefore, the time taken to perform the dock is long and tedious and takes about one or two weeks of work. In addition, all of these operations have a relatively high cost, pollute of the marine environment with the anti-fouling paints used and are also risky for operators and for the boat, because the hauling, the potting and pressure washing involve the lifting of the vessel by means of systems comprising pulleys and cables passed under the hull.

As an example, the patent DE 19734073 assigned on Nov. 12, 1998 to FRAUNHOFER GES FORSCHUNG describes a method involving projecting a high pressure water jet over the surface of the hull which is raised out of the water. The lift to raise the hull out of the water for cleaning has at least two upwardly open U-shaped profiled supports. These have movable carriages, attached to each facing upper U-shank with winches each having a support strap. The cleaning jet has at least two water jet nozzles movable along and perpendicular to the marine vessel longitudinal axis and each positioned on the opposing sides of the hull.

The problem of this solution is that it is necessary that the hull is raised out of the water.

A recent solution of marine plant for the automatic washing of boats, in particular for cleaning the hull, is described in the international patent application US 2008282956 published on Nov. 20, 2008 in the name of the present Applicant. The patent application describes a marine plant for the automatic washing of boats comprising a supporting structure partially submerged, means for cleaning the boat, means for transmitting the motion commanded by at least one motor suitable for reciprocally positioning at least part of said cleaning means in relation to the boat, and a command unit for the operator to control the marine plant.

However, this solution has the problem of the efficient utilization of the system described.
