Description

Lifting and lowering system of a rope, cable or other submerged longitudinal element. Object of the invention

The present invention, as expressed in the statement of this specification, refers to a system for raising and lowering a rope, cable or other submerged longitudinal element whose essential purpose is to facilitate stabilization at any height of a liquid medium, as well as the elevation, descent and any combination between these operations, of a longitudinal element that is in the referred liquid medium; and more specifically a rope rope, a metal cable or an electric cable usually submerged in water, but without discarding other liquid media or other longitudinal elements. Normally, that end or cable, due to its density does not float in the water, using the system of the invention to make it emerge to the surface when so required and basically through an inflatable structure that accompanies or replaces the element to emerge in all or part of its length; said inflatable structure being connected to a pneumatic conduit with which the swelling and deflation of said structure for lifting and lowering respectively the longitudinal element to emerge or submerge is carried out.

The invention is especially applicable to the mooring of vessels in ports, to elevation of fishing nets, and to longitudinal signaling of prohibition or permit of passage within marine ports, without discarding other applications. Background of the invention

Currently, all existing solutions to make longitudinal elements emerge or submerge, such as fishermen's nets, consist of pulling the ends or cables from a floating element such as a ship. These current solutions are formed by weights that exert forces directed to the seabed, by buoys that exert forces towards the surface and by platforms or boats through which the ends are pulled or released. With this, there are inconveniences related to the fact that with the current ways of proceeding, forces fall repeatedly and in a concentrated manner at certain points, generating great possibilities of breakage due to the concentration of efforts. In addition, the current solutions have drawbacks related to the fact that they present systems that are difficult to automate and have very high maintenance needs, since marine environments degrade the mechanical elements considerably.

We do not know in the state of the art systems

or solutions that provide the structures and functionalities provided in the present invention.

The records of the state of the art closest to the present invention that we have located are EP 0502219; EP 1314641; US 7517268; US 5906774; and WO 2004092463. In some of these registers there are devices in which a submerged rope is lifted by applying the lifting force at a point of the rope, so that they have the drawbacks of concentration of stresses mentioned above. Other of these registers are inflatable strings with structures very different from those of the present invention and which include the purpose of con fi guring a salvage float, which is not contemplated in the present invention. Another of the aforementioned patents is a submerged air diffuser device whose structure and purpose are also remarkably far removed from the system of the present invention.

We do not know in the current state of the art any system comprising an inflatable structure of longitudinal tracing that accompanies or replaces a longitudinal element, rope or cable submerged at least in a longitudinal portion of its extension in which a lifting operation is applied , descent, and / or maintenance of a level of height by means of pneumatic conduction means for inflation and deflation of said structure, according to the system of the present invention. Description of the invention

In order to achieve the objectives and avoid the inconveniences indicated in previous sections, the invention consists of a system for raising and lowering a cable, cable or other submerged longitudinal element, where the longitudinal element, cable or cable is in a liquid medium, requiring for the same at least one operation selected between its stabilization at any height of the said medium, its elevation, its descent and any combination thereof.

Novelly, according to the invention, the system thereof comprises an inflatable structure of longitudinal tracing that accompanies or replaces the longitudinal element, cable or cable at least in a longitudinal portion of its extension in which said operation is applied; said inflatable structure being connected to pneumatic conduction means for swelling and deflation.

According to a first embodiment of the invention, said inflatable structure is a coaxial float that radially surrounds the cable, cable or longitudinal element sharing the longitudinal axis thereof.

According to a second embodiment of the invention, said inflatable structure is an inflatable hose braided helically on the rope, cable or longitudinal element, which may include discrete or continuous fastening means thereto.

In a third embodiment of the invention, said inflatable structure is a rectangular or cylindrical float whose opposite edges of longer length include closing means that when fastened together by a closing operation determine a tubular shape in which the cable is located inside, cape or longitudinal element.

In said third embodiment of the invention, said closure means of the rectangular or cylindrical float consist of strips of adherent tissue, other discrete or continuous closing means not being discarded for other embodiments of the invention.

According to a fourth embodiment of the invention, said inflatable structure consists of a first inflatable structure with cable functions; this first structure comprising an inflatable longitudinal section that replaces a section of the cable, of the rope or of the longitudinal element and which has connecting means, respectively, at its two opposite longitudinal ends, with two end sections of the cable, cable or longitudinal element.

In this fourth embodiment of the invention said connection means consist of two appendages of the inflatable longitudinal section located respectively in their two referred opposite longitudinal ends, there being in each appendix a hole in which one of those two cable end sections is knotted, cape or longitudinal element; no other connection means being discarded for other embodiments of the invention.

In a fifth embodiment of the invention, said inflatable structure consists of a second inflatable structure with cable functions that replaces the cable, cable or longitudinal element in its entirety, this second structure comprising an inflatable central section with cable functions that connects on one of its two opposite longitudinal ends with a first non-inflatable end section with cable functions, and on the other of said two ends with a second end section with cable and pneumatic conduction functions for inflation and deflation of the central section.

In said fourth and fifth embodiments of the invention, each of said first and second structures has a tensile strength in the longitudinal direction and elastic deformation in the radial direction equal to or greater than that of the rope, cable, longitudinal element, or section of the same that is replaced by that first or second structure.

On the other hand, in any of the five embodiments that have been referred to, said pneumatic conduction means can be connected to an air pump, compressor, or inflation / deflation equipment that makes it possible to swell and deflate the inflatable structure, either manually or automatically.

In addition, in other embodiments of the invention, the inflatable structure may have at least one area with greater air storage capacity per unit length than the rest thereof, for greater flexibility in said area, establishing various shaped designs not regular to distribute evenly the filling air within said structure.

With the structure described above, the invention has relative advantages in that it provides a lifting and lowering system for a rope, cable or other longitudinal element by applying a force distributed over a large length of said element, so that the possibilities of deterioration by application of forces at a single point they are virtually non-existent. In addition, the invention has advantages relative to its great applicability in various fields, such as lifting of fishing nets, lifting of mooring guides on boats, longitudinal signage within seaports and others. The system of the invention has the great advantage over the state of the art that the means that implement the lifting and lowering functionality are self-contained next to the element that is raised or lowered, also contemplating the possibility that part of this element remains replaced by said means, this substitute section being able to present the mechanical or electrical functions of the rope or cable section it replaces. In addition, the invention has the advantage that it can be easily automated by being operated by an air pump.

Next, in order to facilitate a better understanding of this specification and as an integral part thereof, some figures are attached in which the object of the invention has been shown as an illustrative and non-limiting nature.

Description of at least one embodiment of the invention

Next, a description of five examples of the invention is made referring to the references of the figures.

Thus, in the five embodiments, the cable or end to be lifted 1, 14, 18 is in a liquid medium 4, requiring for that cable or end an elevation 6, descent 8, stabilization at a certain level, or a combination of these operations . For this, in the five embodiments to be shown there is an inflatable structure with a longitudinal layout 2, 9, 10, 16, 20 that accompanies or replaces the cable or cable 1, 14, 18, 23, in at least one longitudinal portion of its extension in which said operation is applied; connecting the corresponding inflatable structure 2, 9, 10, 16, 20 with pneumatic conduction means 3, 19 for the corresponding inflation 5 and deflation 7.

In the first embodiment, the inflatable structure is a coaxial float 2 radially surrounding the cable, cable or longitudinal element 1 sharing the longitudinal axis thereof, as shown in Figure 1.

In the second embodiment, which is represented in Figure 2, said inflatable structure is an inflatable hose 9 which is helically braided on the rope, cable or longitudinal element 1, as can be seen in said Figure 2, which may include systems or means of discrete clamping 40 at the end, cable or longitudinal element; although in other embodiments said means may have longitudinal continuity instead of being discrete.

The third embodiment of the invention, shown in Figure 3, has an inflatable structure in the form of a rectangular float 10 whose opposite edges of longer length include closing means 11 which when fastened together by a closing operation 12 determine a tubular shape inside which the cable, cable or longitudinal element 1 is located, as shown in the aforementioned figure 3. For this third embodiment of the invention, closure means 11 consisting of strips of adherent tissue of Velcro type, however, another type of closure can be used for other embodiments. The rectangular float 10 may have other shapes, such as the cylindrical variant 10 ’shown in Figure 10.

In the fourth embodiment of the system of the invention, shown in Figure 4, said inflatable structure consists of a first inflatable structure with cable functions 16 comprising an inflatable longitudinal section 13 that replaces a section of the corresponding cable or cable. and presenting at two opposite longitudinal ends connection means 15, respectively, with two end sections 14 of said cable or cable; connection means 15 consisting of two appendages of the inflatable longitudinal section 13 respectively located at their two opposite longitudinal ends having been chosen for this fourth embodiment, there being in each appendix a hole in which one of those two end sections 14 of the end is tied , cable or analog, as can be seen in the aforementioned figure

Four.

On the other hand, in FIG. 5 a fifth embodiment of the invention is shown in which the inflatable structure consists of a second inflatable structure with cable functions 20 that replaces the cable, cable or longitudinal element in its entirety, this second one comprising structure 20 an inflatable central section with cable functions 17 connecting at one of its two opposite longitudinal ends with a first non-inflatable end section 18 with cable functions, and at the other of said two ends with a second end section 19 with functions cable and pneumatic conduction for inflation and deflation of the central section

17.

In any of the aforementioned fourth and fifth embodiments of the invention, each of said first and second structures, 16 and 20 respectively, has a resistance to mechanical traction in the longitudinal direction and to elastic deformation in the radial direction equal to or greater than the of the cable or longitudinal element, or section thereof, to which it replaces, so that it can withstand at least the same mechanical forces as the replaced rope so that there is no disadvantage in the corresponding replacement.

On the other hand, in any of the five embodiments shown in Figures 1 to 5, the inflatable structures may be designed in various non-regular ways in order to accumulate different amounts of air in different sections of the structure depending on the specific application. in each case. Thus, Figure 11 shows this possibility, a first non-regular inflatable structure 41 of increasing thickness towards one end being visible in the upper part, in the middle part a second non-regular inflatable structure 42 of decreasing thickness from the center towards two opposite ends, and in the lower part a third non-regular inflatable structure 43 with a thicker off-center intermediate zone.

In addition, also in any of these embodiments, the corresponding pneumatic conduction means 3, 19 can be connected to an air pump, compressor or inflation / deflation equipment 28 that allows inflation 5 and deflation 7 of the inflatable structure 2, 9, 10, 10 ', 16, 20 in an automated or manual way.

In all embodiments, the operation of the system is that in the conventional resting arrangement the weight of the rope, cable or longitudinal element itself plus the weight of the inflatable structure in a deflated state makes all the elements submerged to the corresponding bottom; and when it is desired to make the rope, cable or longitudinal element emerge, the inflatable structure is swollen through the pneumatic conduction, whereby all the components emerge. To re-sink the inflatable structure together with the cable, rope or longitudinal element, the direction of the air flow in the pneumatic conduit is reversed.

Figure 6 shows a first application of the system of the invention for raising the guide of a boat mooring 26.

Thus, in this first application, it is a question of making a guide 23 emerge which is used in moorings of boats that use a concrete dead 24 located on a seabed 25, the dead 24 being attached to the mooring 22 of the vessel 26 furthest from pier 27, and is moored 22 to guide end 23; connecting said guide end 23 with the spring 27 after running along the corresponding bottom 25, any of the devices of the five embodiments of the invention shown above 2, 9, 10, 16 and 20 can be used to replace or accompany this guide end 23 Thus, the inflatable structure chosen according to the invention travels the entire length of the guide line 23, with more air volume being available in a nearby area of the boat that is where the guide line 23 is intended to be accessed and where maximum flexibility is required. . When the vessel 26 arrives, the structure 2, 9, 10, 16, 20 is swollen with the air pump 28 that is located on the pier 27, causing the guide end 23 to emerge and allowing the crew of the vessel 26 to access simple way to said guide end 23 to immediately carry out the farthest mooring to the spring 27, while the moorings closest to the spring 21 are carried out in a conventional manner. With this, the distant mooring 22 is carried out in a simple clean way and without having to travel the entire length of the vessel 26 with the guide end 23 that had been conventionally taken at the pier 27. Once the vessel 26 is moored, the pressure pump 28 is used in the reverse direction to remove all the air from the inflatable structure and so that it is submerged so that everything is ready for when the boat 2 6 has to be untied and leave the spring 27. In this figure 6 it represents the described application, the upper part, referenced as 36 represents the situation in which the pier is with the boat moored, while the lower part of the figure 6 referenced as 37 represents the situation in which the pier is without boat showing the arrows between both situations the complete reversibility in the elevation and descent of said guideline 23.

On the other hand, in the figure 7 the application of the previous figure 6 has been represented as it is carried out in the state of the art, without using the system of the invention, the situation in which the vessel 26 is moored has been referred to as 38 and like 39 the situation of the lower part of said figure 7 where the pier 27 no longer has a vessel. According to this figure 7, the guide line 23 must be caught on the dock and moved along the entire length of the boat 26 until it reaches the end where it is possible to make the mooring far to the dock 22.

A second application of the system of the invention is shown in Figure 8, in which any of the inflatable structures 2, 9, 10, 16, 20 provided by the five described embodiments could also be used, this application consisting in the elevation of a fishing net 30 in a liquid medium 4, in this case open sea, and the fishing net 30 being connected to net buoys 29, as illustrated in Figure 8, so as to raise said net 30 or to sinking it provides or removes air to the inflatable structure from the vessel 26, as illustrated in the aforementioned figure 8.

Another possible application for the system of the invention is to perform dialing functions.

or signaling passage to vessels 26, as shown in Figure 9, where reference 34 shows a permitted passage situation and reference 35 a prohibited passage situation that is carried out by raising an inflatable structure 2, 9, 10 , 16, 20 which could also be any of the five embodiments provided in this section. The reference 32 of this figure 9 shows the direction of passage allowed to the boat 26 when the inflatable structure is deflated, while the reference 33 of the right part of this figure 9 shows the direction of passage of the boat, other than the previous one when the corresponding prohibition was signaled. The reference 31 represents the marker or signaling device that is seen by the vessel 26 to know that it cannot pass through a certain area of the port 27 in which that marker 31 is applied.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement The main object of the invention is a lifting and lowering system of a rope comprising an inflatable structure with a longitudinal layout that accompanies or replaces a portion of the rope and is connected to pneumatic means for swelling or deflation. Document D01, considered to be the closest in the state of the art, discloses an apparatus for ascending and descending an underwater pipe comprising floats that are connected along the pipe by means of belts. These floats are interconnected with each other by a hose that is connected at one of its ends to an air compressor or an inert gas bottle that feeds the floats (see column 2, lines 91-67; column 3, lines 3-17 ; figures). In view of the preceding paragraphs, the features of claims 1,4 and 10 are already known from the document. D01 Therefore, these claims are not new in view of the state of the known art (Art. 6.1 of LP11 / 86). As for claim 5, the fact that the belts are made of adherent fabric is considered a design option obvious and therefore lacks inventive activity (Art. 8.1 of LP11 / 86). Document D02 discloses a tension cable that connects to a source of pressure to be swollen its different chambers, and is provided with connection means at its ends (see figures). It is considered that one skilled in the art would attempt to combine the main parts of document D02 with document D01 of the nearest state of the art to obtain the characteristics of claims 6-9 and 11 and have a reasonable expectation of success. Accordingly, claims 6-9 and 11 are considered to lack inventive activity based on what is disclosed in documents D01 and D02 of the prior art (Art. 8.1 of LP11 / 86). Document D03 discloses a system for the recovery of submerged ships comprising a row of floats along the ship that are interconnected by a pipe for swelling and deflation, and that have some appendages through which cables or chains to secure said floats to the wreck. It is considered that one skilled in the art would attempt to combine the main parts of document D03 with document D01 of the closest prior art to obtain the characteristics of claims 2 and have a reasonable expectation of success. Accordingly, claims 2 are considered to lack inventive activity based on what is disclosed in documents D01 and D03 of the prior art (Art. 8.1 of LP11 / 86). Referring to claim 3, the feature of winding an inflatable hose around the end is considered as one of several obvious possibilities that a person skilled in the art would select according to the circumstances, without exercising inventive activity, to solve the problem posed.
