Description

The claimed technical solution relates to ship devices, in particular to equipment for anchoring, namely to floating anchors in the form of a parachute, designed for use on small vessels and is intended to reduce the speed of the vessel and to orient the vessel in the wind and wave.

Currently, floating anchors are widely used due to their relative portability, which allows the use of these products in the current situation both in everyday life, fishing, and in the activities of small fishing industries.

Various models of parachute anchors are known, and the most common on the market are cone-shaped parachute anchors. An example of an anchor for anglers is the "Floating anchor" (Internet site https://rykzaki.ru/pages/dlya_chego_nujen_plavuchiy_yakor_ryibolovam/, posted on February 11, 2020) of a conical shape, the use of which not only contributes to successful fishing, but also increases safety on large bodies of water, since a correctly set floating anchor keeps a small boat always with its bow against the wave, moving in a drift with the wind, with constant braking by a water anchor. The disadvantage of parachute anchors of this form is a long time for opening and setting the parachute in the desired position and also a long time for assembling the parachute anchor.

Also known are parachute anchors having a round web shape. Thus, an analogue is known, the patent of the Russian Federation for the invention No. 1740241 dated 12/20/1984, published on 05/10/1997, protecting a floating parachute anchor. This invention relates to shipbuilding, namely to floating anchors for industrial ships. The purpose of the invention of the analog is to provide the possibility of changing the area of the dome during the operation of the anchor, as well as increasing the manufacturability, reducing the complexity of assembly and ensuring the interchangeability of the anchor elements. The dome of the floating anchor-parachute is made detachable, consisting of interchangeable flat elements having the shape of isosceles trapezoids and equipped with eyelets for connecting the elements to each other in several places and eyelets for fixing the lines. When connecting flat elements, a central opening of the dome and radial slots are formed. By connecting together more or less flat elements, a dome of the required effective area is obtained, and the central hole and radial slots formed when the elements are connected contribute to the stabilization of the dome.

A common feature of the proposed technical solution and analogue according to the RF patent for invention No. 1740241 is the presence of a dome.

Unlike the claimed parachute anchor, despite the similar principle of operation, the analogue according to the RF patent for invention No. solution is a single canvas with sewn-in floats and weights.

An analogue is known, a floating anchor according to the RF patent for the invention No. 2326018 dated 11/02/2006, published on 06/10/2008, the elastic base of the floating anchor consists of a chain mail patch, lined with canvas and fixed in the underwater part of the bow of the vessel, and when interacting with fluid flow in waves creates a hydrodynamic force, the vertical component of which N reduces the pitching amplitude, and the horizontal component T creates an additional traction force. The device allows a ship in distress to move against the oncoming wave.

In this case, in the analogue according to the RF patent for invention No. 2326018, it is proposed to use a chain mail patch available on each ship as the basis of a floating anchor. These plasters of various sizes are included in the kit of ship's rescue devices. However, such a floating anchor is more complicated to operate and requires more time to install than the claimed solution.

A marine parachute anchor is known according to US patent No. US20220266956 dated November 2, 2020, published on August 25, 2022, the invention relates to a parachute marine anchor system deployed from a payload tube. A parachute marine anchor system is provided, suitable for launching from a ship containing at least one payload tube, said payload tube containing a payload container that contains a parachute sea anchor, in which said parachute sea anchor contains a buoy tied to to it, wherein said payload container is attached to said vessel.

Common features of the proposed technical solution and the prototype according to US patent US 20220266956 are the presence of lines, the formation of a dome.

The differences between the prototype and the proposed technical solution are due to the design features, namely the prototype: there are no sewn-in floats and sinkers, there is a separately tied buoy, the dome is made of a pipe, and if the pipe does not open like a parachute, then the efficiency of the prototype device is low.

The technical problem to be solved by the claimed utility model is the lack of ease of use of anchors of known designs. The claimed utility model was developed in order to solve the above problem and increase the efficiency of using a floating parachute anchor.

The purpose of the proposed technical solution is to expand the arsenal of technical means in the production of floating parachute anchors and their functionality, as well as to overcome the insufficiently high ergonomic characteristics of such products noted in the prior art.

The technical task of this solution is to create a floating parachute anchor of optimal parameters and a design that would be more convenient to manufacture and operate.

EFFECT: simplification of production efforts in the manufacture of an anchor-parachute, as well as simplification and reduction of time for installing a floating anchor-parachute, fixing the working position due to weights and floats and stopping its use due to a cord for quick assembly.

The technical result is achieved by the fact that the inventive floating anchor-parachute is a fabric made of soft dense fabric that does not let water through, having the shape of a rectangle, soft dense tapes are sewn along the perimeter of the fabric, across and along the diagonals of the fabric, which ensure the strength of this product, and the perimeter the web is sheathed in such a way that the edges of the web are gathered, and at the intersection of the tapes with the edge of the web there are loops formed from the same tapes and used to fix the slings tied to the loops, and floats are sewn along the entire length of the upper part of the web, and along the edges sinkers are fixed on the lower part of the canvas on the slings.

The proposed new design of the floating parachute anchor is easy to manufacture, quickly opens, fixes the working position using the energy of water and wind, thereby reducing the drift speed, and is also easy to assemble.

The essence of a utility model is expressed in a set of essential features sufficient to realize its purpose.

The essence of the proposed technical solution is that the floating anchor-parachute includes slings and a dome, and the dome is a single sheet of soft dense water-resistant fabric, having the shape of a rectangle, along the diagonals of which soft dense tapes are sewn, giving strength, and along the perimeter the canvas is gathered up, and at the points of intersection of the tapes with the edge of the canvas, fixing loops formed from the tapes are placed, slings are tied to the loops, all the slings are connected to each other, a single sling is tied to the place of their connection, which is attached to the vessel with its other end, while along the entire along the length of the planned upper part of the canvas intended for immersion in water, floats made of a material with high buoyancy are sewn in, and along the edges of the lower part of the canvas, which is deeper under the surface of the water, weights are fixed on the slings, while one of the two loops located along the edges of the floats, attached cord for quick assembly.

The claimed technical solution is illustrated by the drawings of Fig. 1 and 2.

Floating anchor-parachute, the design of which contains: a rectangular canvas of the dome 3, along the diagonals of which ribbons 1 are sewn, at the intersection of the ribbons 1 with the edge of the canvas 3, fixing straps 5 of the loop 4 are placed, formed from ribbons 1, straps 5 are tied to the loops 4, and along the entire length of the upper part of the web 3, intended for immersion in water, floats 2 are sewn in, made of a material with high buoyancy, and along the edges of the lower part of the web 3, weights 6 are fixed on the slings 5.

The proposed floating anchor-parachute contains a canvas 3 of soft dense fabric that does not let water through. Canvas 3 has the shape of a rectangle. Soft dense tapes 1 are sewn along the perimeter of the fabric 3, across and along the diagonals of the fabric, which ensure the strength of this product. The perimeter of the canvas is sheathed in such a way that the edges of the canvas are gathered.

Loops 4 are placed at the intersections of the tapes 1 with the edge of the canvas 3. The loops 4 are formed from the same tapes and serve to fix the slings. Slings 5 are tied to the loops 4, and the larger the size of the canvas, the longer the slings. The number of slings 5 attached to the web 3, in practice, can be from four or more pieces, depending on the size of the web 3. All slings 5 associated with the web 3, at the other end, are tied together into one knot, forming a loop, attached to this loop (loop to loop) single sling 8 1.5-3 meters long, which is directly attached to the vessel at the other end.

Floats 2 are sewn along the entire length of the upper part of the fabric 3. Floats can be made of various materials with high buoyancy.

Along the edges of the lower part of the web 3, on the slings 5, sinkers 6 are fixed, which can be made from almost any sinking material (for example: lead, iron, tungsten). Fixation sinkers 6 can occur in various ways (stoppers, compression, knots).

During the operation of a floating parachute anchor, a dome is formed from the forcing water pressure, which serves to reduce the drift speed of the vessel.

The operation of the inventive floating anchor-parachute implies the following sequence of actions: first, the end of a single sling 8 is fixed to the vessel, then the parachute is lowered into the water, sinkers 6 down; the ship is displaced by the wind and current, and the parachute opens due to water pressure and slows down the drift of the ship.

The advantage of the inventive floating anchor-parachute relative to analogues is that the parachute quickly rises to the working position due to the correct location of the weights 6 and floats 2, and is also quickly assembled from the working position and folded for storage.

In order to quickly assemble the parachute anchor from the working position, you need to pull the quick assembly cord 7, tied to one of the two loops located at the edges of the floats. The function of the cord for quick assembly 7 is as follows: by pulling the cord 7, the parachute is folded from the working position to the non-working position, thus it can be easily and quickly pulled by this cord to the vessel. The cord 7 is tied to the upper left or right loop of the parachute as shown in FIG. 2. When using the parachute anchor in the working position, the cord 7 must be loose. If you do not use the cord 7 for assembly, you will have to pull on a single strap 8, i.e. you can say “pull the ship to the parachute”, and this can be very difficult with a large size of the ship, because. the parachute, being in the working position, strongly resists the water.

Compared with the known devices floating anchors, parachutes, the proposed design has greater convenience and safety of operation and storage. Consumer qualities are much higher than those of known analogues.

The possibility of repeated reproduction of the claimed design results from the method of its industrial configuration, which makes it possible to reproduce the claimed device of a floating parachute anchor on an industrial scale.

Such a combination of versatility, achievement of the possibility of multiple reproduction with relative ease of manufacture in the prototype is not achieved.

Based on the foregoing, we can conclude that the proposed technical solution meets the criteria of "novelty" and "industrial applicability".
