Description

"IMPROVEMENT IN CIRCA FLOATING DECONTENTION OF SURROUNDING POLLUTANTS CONTAINED IN WATER COURSES".

This descriptive report deals with a floating fence containment improvement of supernatant pollutants contained in watercourses of the type intended for use in installations to remove suspended organic matter from polluted watercourses, as described and illustrated in Case PI0306256-2, 12/19/2003, by the same proprietor, and more particularly as set out in the subsequent proceeding PI 0504903-2, also by the same proprietor, but stated on 31/10/2005.

The proposed floating fence improvement as evidenced in the aforementioned process PI 0504903-2 can also be applied in isolation as a barrier to contain diffuse or polluting loads released into channels, rivers, or other watercourses; or whether these pollutant loads are brought by stormwater and discharged untreated, or by accidental spillage of polluting products that come in any way in contact with the watercourse, becoming naturally supernatant or induced by water diffusers. provided at the bottom of the watercourse.

Case PI 0504903-2 reports the state of the art pertaining to the subject matter contained therein and which also constitutes the state of the art to be considered in the present case, which highlights the fact that water pollution and environmental deterioration in Large urban centers are phenomena of modern civilization, and the formation, development and population densification create and aggravate health problems, because in large population groups, the availability of areas in urban lots and the capacity of sanitary deposition are not sufficient to cope with the generated load. mainly the deposition of solid waste and waste solutions directly discharged in excessive volume into the watercourses does not allow the occurrence of the phenomenon called self-purification, making these watercourses, whether rivers, dams and reservoirs. large urban centers, and true sewage clear sky,

Within the context of the state of the art reported in the process PI 0504903-2 it is reported that high investments in a public sewage system are required for a reversal.

The efficiency of this process of environmental deterioration allows for the rapid and safe removal of wastewater, waste and liquid waste from human activities, as well as for the treatment of this removed material.

Accordingly, and in accordance with the above, it is added5 that the facility for removal of suspended organic matter present in polluted watercourses, subject to patent application PI0306256-2, for the containment and direction of solid material along the course. a floating fence, called a garbage fence, longer than the width of the watercourse, which is flexibly extended between the margins of the latter to allow the formation of an arched surface of the watercourse, thereby facilitating retention and conduction of coarse waste such as bottles, plastics, paper and other materials to one of the margins of this watercourse where such waste or debris is removed from the watercourse. This floating fence still serves as a service passageway for operators to cross from one bank to another.

Said fence, as reported, is constructed by modular metal structures and self-reinforcing frames such as jointing, interconnecting and pivoting elements between these structural modules to ensure buoyancy, linear flexibility and compatible length as between the margins. Since all these factors imply in high costs of design and execution of this floating fence, it ends up being built for each specific case, often not allowing a rearrangement of its final design depending on the dimensions of each floating module used. .

Considering the containment of coarse waste such as bottles, plastics, paper and other materials to one of the banks of this watercourse where such waste or debris is removed from the watercourse, one of the major villains in watercourse pollution is tires. that are thrown into rivers and their tributaries, especially in urban areas of these watercourses, making even the displacement of these waters more difficult in their natural course, because due to their density they are deposited in the bottom of the watercourse, being carried by the flow of this water. which as a result of this becomes slower.

Therefore, within the scope of PI 0504903-2, a containment proposal has been proposed that, by blocking and driving to an area from the removal of natural or induced supernatant pollution from domestic and / or industrial sewage existing in the watercourse itself. As well as the removal of supernatant and non-degradable solid objects directly thrown into the watercourses, it enables: a) the elimination of aspects that are detrimental to the aesthetic sense, as well as the disappearance of foul odors; b) the use of water resources for future reuse; c) the use of urban watercourses as elements of recreation and sporting practices, and d) the conservation of natural water resources against excessive pollution and its maintenance under full conditions.

Still regarding the process PI 0504903-2, it was also another objective to be achieved, the fact that a floating fence containing supernatant pollutants contained in watercourses could be made that could be made with scrapped objects that end up being thrown along the courses. so that this reuse would have a double benefit, that is, the reduction of the costs of production of this fence and the disposal by disposal of an object that causes pollution and obstruction of the watercourses, because it is a garbage of deposition in the bottom of the courses. water

Process PI 0504903-2 had yet another goal to be achieved by providing a floating fence containing waterborne pollutant superstructures that were designed by assembling small modular parts and fully adaptable to any size of water width. waterbed so that it can be quickly installed in any waterway regardless of its size.

Process PI 0504903-2 also proposed, as yet another objective to be achieved, that a floating fence containing supernatant pollutants contained in watercourses would be provided which would allow waste to be discharged into regions where there was no efficient collection network. in the watercourses were retained and removed to the degradation sites, thus avoiding its deterioration along the watercourse and, consequently, the deterioration of the watercourse itself.

Accordingly, said process PI 0504903-2 innovated, in that it disclosed a floating, polluting containment fence contained in watercourses which had a length greater than the width of the watercourse to be flexibly extended between the latter, allowing the formation of an arched belt on the surface of the watercourse, thus facilitating retention and conduction of coarse waste such as bottles, plastics, paper and other materials to one of the margins of this watercourse where such debris or waste was removed. water course; said floating fence treated in case PI0504903-2 could still be used as a service bridge for cross-border operators of the installation from one bank of the watercourse to another.

Process PI 0504903-2 objectively proposed that the floating fence then disclosed would comprise an aligned composition of a plurality of floating modules, each of which is designed by scrapping scrap, preferably of tires or tire casings mounted side by side, defining each other. for each module, vertical walls and one upper horizontal wall; each module thus defined is interconnected and anchored side by side with another similar module by means of hardware directly attached to each tire casing unit and steel cables, which are extended through all modules that make up the fence alignment and its ends are anchored near fasteners provided near the banks of the watercourse; whereas on the upper horizontal wall and one of the vertical walls of the fence thus formed, a flexible and waterproof platform-defining belt was applied in its horizontal portion and a retaining bulkhead in its vertical portion, allowing the movement of workers from one side to the other. watercourse and the containment of all naturally occurring or deformed supernatant waste in that watercourse.

The fence described in the mentioned process PI 0504903-2 represented and still represents a clear and undeniable advance towards the removal of supernatant solid residues present in watercourses, which operation can be performed in a practical and efficient manner, a fact that is not prevented the Holder from continuing his research in the sense of implementing an even more efficient floating fence,

Within this context, when seeking to innovate on the subject matter described in process PI 0504903-2, the Holder and the Applicant now came to the project presented here, which proposes an improvement in floating fence and containment of supernatant pollutants contained in watercourses, which provides floating modules assembled to form a floating structure containing supernatant pollutants which, as proposed in the process PI 0504903-2, has a length greater than the width of the waterway thus allowing said structure to be flexibly extended between the banks of the watercourse, defining an arched belt in the same surface.

Within the scope of the present invention, the floating module has a set of screens that hangs from its front wall and has at its lower end a ballast represented, for example, by an iron bar, which has the function of keeping the screens close to the bed. of the bottom of the watercourse.

The screen of each floating module has a rear screen behind it, and the two screens are produced to retain supernatant solid waste, but allow the flow of compressed air flows produced by a nite-mounted aeration system. bottom of the watercourse.

The screens of each floating module can be raised by a pulley system, or alternatively, by the hoist-like lifting arm, which pulling up the screens causes the supernatant solid debris to be naturally removed from the hoist. water and in an alternative form are conveyed to a conveyor conveyor carrying this material from one floating module to the next and thereafter until all of the material collected is destined for one of the banks of the watercourse where it is then concentrated. and properly packaged.

The improved floating fence object of this invention patent departs from the general concept described in process PI 0504903-2 and innovates the design solution that allows the effective removal of supernatant residues that are present in the watercourse.

The improved floating fence object of this invention patent will be described in detail with reference to the related drawings below, in which:

Figure 1 illustrates a schematic and top view of a generic watercourse example through which an improved floating structure is assembled and as proposed herein, with said view permitting observation of the floating modules forming the aforesaid fence. and the screens mounted in front of said floating modules, as well as the anchor points of the fence structure near the banks of said watercourse;

Figure 5 illustrates a schematic top view of a generic watercourse example through which a floating floating structure such as that proposed herein is mounted which, however, employs a constructive variant of the floating modules, said view being shown in FIG. allows the observation of the floating modules themselves, the screens mounted in front of said floating modules, the conveyor belt that is used to drive the volume of supernatant solid waste (after collected by the screens) towards a bucket where such material is initially stored, as well as the points anchoring the fence structure near the banks of said watercourse;

Fig. 6 illustrates a schematic sectional view similar to that shown in Fig. 3, but relating to the constructional variant of the floating module which also incorporates the material treated in the present Utility Model patent; and

Figure 7 illustrates a view similar to the one depicted in Figure 4, but with respect to the constructional variant of the floating module, said view as shown in relation to said Figure 4, the action of the aeration system that operates in conjunction with the fence , as well as the means of hoisting the screens thus collecting the supernatant residues present in the watercourse;

As illustrated by the above related figures, the present invention patent proposes a fluctuating refinement of containment of supernatants contained in watercourses, which consists of an aligned composition 1, which is formed by a plurality of floating modules 2 each one of which is designed as a hollow body 3, having essentially a preferably parallelepiped shape.

Each float module 2 incorporates, on the hollow sides of its hollow body 3, a side coupling means 4, which allows any float module 2 to be pivotally connected to another float module 2 and so on to define the aligned composition. 1.

Each of the floating modules 2 acts as a breakout unit, having for this purpose safety grids 5, as can be better understood by observing figures 2, 3 and 4.

From the front face of the floating modules 2 hangs a screen 6 which has at its rear a pass-through screen 7, (more easily seen in figure 2), which provides the space separating the screen 6 from a floating module 2 and the screen 6 of the module floating 2 adjacent.

The webs 6 and 7 have an inferior ballast 8 which holds two webs properly positioned with respect to the water flow F through the watercourse C, said ballast means 8 being defined with a metal bar segment 9 of suitable weight.

The screens 6 and 7 are positioned to create a lock which prevents the passage of supernatant solid residues R, which can be further forced or pushed upwards by a flow of compressed air bubbles B (which are specifically depicted in figures 3, 4, 6 and 7), which is generated by an aeration system 10 which is arranged near the bottom bed C as can best be understood by observing the same figures 3, 4, 6 and 7.

A cable system 11 connected to the lower end of bars 6 and 7 allows them to be raised (hoisted) whenever an optimal supernatant solid waste concentration R is reached, as specifically shown in Figures 4 and 7.

The lifting of the screens 6 and 7, as schematically indicated by the arrow B of figures 4 and 7, allows the solid supernatant residues R to be lifted and removed from the water flow F of the watercourse C, thus allowing such material to be removed from the course. The cable system 11 operates in conjunction with the respective pulleys 12 and can be mechanically driven by respective motor units M incorporated into the frame 13 which receives the pulleys 12 in floating module 2.

The present utility model patent further provides a constructive variant for the floating module 2 which can be appreciated in figures 5, 6 and 7.

The floating module 2 constructed according to the proposed construction variant differs from the floating module 2, as shown in figures 1, 2, 3 and 4 in that it includes a conveyor belt 14 which crosses over all floating modules that form the aligned composition 1, said belt. The conveyor 14 is made up of mutually articulated plates 15 (especially shown in Figure 5) and is driven in the direction indicated by the arrows C, leading the solid waste captured by the screens 6 and 7 towards a bucket 18 positioned on one of the stroke margins. water C.

The floating module 2 of the variant depicted in figures 5, 6 and 7 further differs from the floating module shown in figures 1, 2, 3 and 4 in that it has winch-like arms 16 and particularly visible in figures 6 and 7, which in their upper ends, they have their sheaves17, which lead the cables 11 to their respective M motor units.

The variant of the floating module 2 is shown schematically and in operating condition in Figure 7, where it can be seen that the lifting of the screens 6 and 7 naturally leads the volume of supernatant solid waste R towards the conveyor 14.

The fence treated herein, in either of its two modes, allows supernatant solid residues R present in a water course C, such as the one pictured schematically, to be easily removed from that water course thus providing that the presence of such a contaminant is reduced.

The figures portraying this invention patent, for practical reasons, demonstrate two examples of fences that are assembled with up to four floating module units 2, a fact that does not, in real terms, construct floating fences with larger amounts of floating modules, Arched or transversely aligned with the flow of water, the present fence may therefore be used and installed in watercourses of varying widths.
