Description

PROTECTION AGAINST BALANTS BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION This invention relates generally to anti-fouling devices for ship hulls and more particularly to a flotation closure assembly for protecting against marine growth for the lower part of the body of a vessel. boat anchored on a dock, 2. DESCRIPTION OF THE PREVIOUS TECHNIQUE It has been established for a long time that the hulls of unprotected ships, when left submerged for a time in a body of water, are susceptible to damage by the fouling of various organisms marine A number of invention have been designed to reduce this damage. For example, many types of permanent helmet liners have been used that act as a physical barrier between the hull of a boat and the water immediately surrounding it. However, such coatings usually do not protect the hull from the accumulation of barnacles and algae. In some cases, such coatings also reduce the performance of the ship due to the weight of the coatings. Other coatings use toxic substances to retard the incrustation of marine life, but there are significant environmental drawbacks with the use of such toxic coatings and, consequently, such coatings become less practical.

Protectors against marine growth are known in the form of impermeable covers against water complementary to the form under the water of a ship. These covers after being placed around the lower body of the ship are then filled with liquids that inhibit the growth which can only be fresh water or water containing chemicals against scale formation The problem with such covers is that they are difficult to maneuver around the bottom body of the boat and have been resorted to, to facilitate this task, but none of them has been more advantageous than another and all have been burdensome Other devices are available which serve to protect the hull of a ship only while the ship is at rest, since marine life is not capable of damaging the hull of the ship when it is in motion One such device is described in Cox US Pat. No. 4,026,233 which describes a helmet cover of portable safety for a marine vessel that can be quickly discarded from a vessel that has been subjected to hull damage that destroys the water-tight integrity of the hull which could cause the vessel to form inlays and eventually sink. The safety cover is a flexible, waterproof protection, of material dimensioned and configured to conform in a manner joined to the bow, sides and keel of the boat, with the cover being easily attached to the bow by means of a tie and unfolded against the outer bottom of the boat The device has an auxiliary use to form a cover around the boat to clean the hull. US Patent No. 4,046,094, to Preiser et al., describes a system to prevent and inhibit the growth of the entire marine community that forms inlays in the hull of a boat while it is resting in salt or marine water A pipe or pipes that have no illas distributed along the same run the length of the keel Fresh water is supplied to the pipeline which flows out of the nozzles and up to the entire hull to create and maintain a limiting layer in freshwater movement A cover also serves to inhibit the formation of scale A cover comprising overlapping, segmented, opaque curtains hang down the weights from the deck of the ship. US Patent No. 4,693,200 to Noble, describes the apparatus for sealing and / or treating in a protective manner the submerged portion of a body floating on a surface of water, such as a ship's hull, to prevent or reduce the growth of marine organisms in the submerged portion The apparatus is formed of a generally rectangular frame having a waterproof cover attached to the attached water at the same large enough to cover the submerged portion of the floating body The pumping means are associated with the frame, mounted on the rear tubular member, with the pump adapted to pump water into the side and rear tubular means to cause the rear member to be submerged and moved pivotally downwardly around the front float member so that the boat can move through of the rear member submerged in the area defined by the rectangular frame US Pat. No. 5,152,242 to Bradley discloses a protective helmet cover for a stationary boat floating in a body of water A flotation collar forms a first closed figure that approaches the shape of the perimeter of the hull on the surface of the water US Patent 5,279,244 of Pérez-Collazo discloses a protector against the formation of scale in the form of a flexible cover complementary to the body under the water of a hull of the vessel, the which is floating negatively and, when not in use, is stored in the lower part of a spring Anchoring Therefore, there is a need for a helmet protection device that significantly reduces the damage to marine life that is embedded in boat hulls and that is also relatively simple to install, operate and maintain. Such a required device must be capable of adapting to a variety of boat helmets, environmentally acceptable and relatively inexpensive The present invention meets the needs and provides additional related advantages COMPENDIUM OF THE INVENTION The present invention is a protective hull cover for a stationary boat that floats on a body of water, the surface of the water that defines a water line in the hull of the boat The unit when not in use, floats in the space of the mill and is attached to any rock or pile Floats are attached to the ends of the lines to Easily removed The boat is carried slowly over the floating aft section Like the aft section, with this cover, it is emptied up down the bow of the boat, the downward cleaning rod pushes against the hull helping to dislodge any sludge or organisms that have come together. The umdad can then slide under the boat until the stern cleaning section press up on the section aft of the boat The lines are then tied to the boat cleat BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a top isometric view of a barrel protection according to the invention. FIG. 2 is a top plan view of a barnacle protection according to the invention Fig. 3 is a side view of the protection of barnacles, floating on top of the water, before entering a boat Figure 4 is a side view of the protection of barnacles with a boat entering and showing the action of a cleaner cleaning the bottom of the hull as the boat enters. Fig. 5, is a top view of the protection of barnacles with a boat in its bottom. Into the protection, fresh water is pumped and excess water taken out through the check valves. DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Referring now to the drawings in which similar numbers refer to the same element, it is shown in FIGS. 1 and 2 generally, a barrel protection, constructed of three main parts, a semi-rigid frame 11 of flotation made of PVC tube filled with foam, polyethylene bubble wrap and freshwater descending wash system 14 The frame 11 it is usually cut in lengths of 1830 cm, 30 cm and -5 cm. The bow section 13 forms the "v" of the bow.
