Description

DESCRIPTION

Integral system for suction of materials in water (sisma)

Technical sector

Fishing maritime sector.

This sector includes the activities included in division 03 of the group of the National Classification of Economic Activities (CNAE), which includes shipbuilding (point 30) and, more specifically, floating structures (30.11).

Background of the invention

Currently, there are certain systems whose purpose is to improve dredging capacity, such as hydraulic systems, pressurized water jets, etc. Current dredgers base their operating principle on a suction head attached to a tube through which, thanks to a pumping system, it makes the material rise from the seabed, together with a large amount of water, into a container container, called pitcher, located on the boat or on the surface. In this pit, the densest sediments are deposited at the bottom while, as the pit fills with water with floating sediments (or cloudy water), it overflows or overflows at the top, falling directly into the sea. The dredging process and the overflow of cloudy water into the sea continues throughout the dredging process, until the pit is as full as possible with dense deposited sediments.

The antecedent to the present invention is the stationary suction dredger, since they carry out the dredging through a pipe installed on a rigid structure. The pipe can also be equipped with a cutting element to increase its efficiency. These dredgers have one or more legs for fixing to the seabed during the work. The dredged material is re-propelled and directed through a pipe to the dumping site.

On the other hand, there is also the amphibious multipurpose machine "WATERMASTER", also known as "The Finnish spider". The purpose of this machine is suction dredging. This machine is characterized by its ability to start operation without assembly times, cranes or tugs, because it is amphibious and can walk independently to enter and exit the water. You also don't need winches, cable or support boats, as it has its own propulsion system so you can get to the job site independently.

The actions previously carried out for the cleaning of sludge in the Mar Menor, the location for which the present invention will be destined, have been mainly carried out by the Finnish spider. However, said spider is a large machine, which is far from the size of the product presented in this document. In addition, it also causes damage to the seabed, contrary to the present invention.

In recent years, environmental regulations in Spain, since our incorporation into the European Union with the signing of various environmental preservation agreements, have become increasingly strict. Currently, there are specific regulations that directly affect dredging activities and that have increased the environmental requirements that must be met during them. Therefore, only eco-sustainable dredging processes will be competitive, leaving the current conventional systems in disuse.

Explanation of the invention

The invention was born to solve the problem of accumulation of mud on the shore of the Mar Menor beaches. In recent years, the salty lagoon has suffered a great deterioration with the discharge of nitrates, which have increased the level of phytoplankton in its waters and has caused that, in the accesses to the sea, the sand has become muddy areas that prevent that bathers can enjoy the coast.

The SISMA system is a device designed for the extraction of sludge, sludge and sediment using four water pressure flows towards the seabed while sucking these particulate components through an extraction system. This material is then taken to the filters, where the water is separated, which returns to the sea in the same initial conditions, but retaining the mud in bags arranged on the shore, which are later transferred to a point where it can be deposited.

Another function of the SISMA system is to extract the sludge that is deposited at the bottom of the reservoirs as the dirt stagnates in the water. Over time, the lack of fluidity in the reservoirs, added to the dragging of sand moved by the wind, causes sludge and sludge to accumulate at the bottom of these constructions, hindering their use.

This system comprises a set of components that allow the extraction of sludge, offering the best option to the seabed and the ecosystem. It works with the sludge extraction device, from now on called the Medusa device, which is surrounded by the anti-cloud barrier. Likewise, the sludge is transported to the filtering system, through a distribution pipe. This Medusa device is connected to an electrical generator that allows it to function.

The Medusa device is the main protagonist of the SISMA system. Said device is on the surface of the water, thanks to a float. It contains a suction pump that is introduced into the water, without touching the seabed or the mud surface, thanks to the wheel stop system. It also contains along its perimeter an anti-cloudiness mesh, which prevents the agitation of the mud from moving, and some stirrers, which remove the bottom by means of pressurized water, facilitating the work of the suction pump, as well as the suction drawer, in those cases in which it is required, because there is a considerable depth.

Preferred embodiment of the invention

In the attached figures you can see the operation of the system and the Medusa device, the explanation of which can be seen below. The mode of implementation intended to reduce the sludge of the salt lagoon of the Mar Menor will be assumed, thus not damaging the seabed of this.

In Figure 1 you can see the elements that are part of the SISMA system. It works with a sludge extraction device, from now on called Medusa device (1), a modular and configurable system that adapts to different types of hydraulic installations (reservoirs, canals, ponds, etc.), without altering their normal operation. This device is rectangular and it is recommended that it have a depth of between 0.6 and 1 meters. The jellyfish device itself is surrounded by an anti-cloudiness barrier (2), which prevents a mud stir from being generated, and by the water line (6).

The mixture of water and sludge is transported through a distribution pipe, connected to the connector-outlet of absorbed materials corresponding to the Medusa device, to the seashore, where the filtering system (4) is located. This filtering system consists of a series of bags that function as filters (5), which let the clean water flow and retain the sludge to be eliminated.

It should be noted that the SISMA system works by means of an electric generator (3) that is located next to the filtering system, on the shore.

In Figure 2 you can see the different elements with which the Medusa device is composed. This device is kept afloat on the surface of the water (15) thanks to a float (8) made of expanded polystyrene (other materials can also be used). This element is the one that allows the machinery to be transported without damaging the seabed, since contact is not established with the bottom when moving the device (in the case of a reservoir, it would not touch the wall either and it would prevent the rupture of the cover). Additionally, a steel grid can be integrated in the upper part of this float to allow passage over the surface of the machinery. At the bottom of this device, four tubular injectors, called removers (13), controlled manually, placed in each corner of the Medusa device, inject a flow of water at a regulated pressure towards the seabed (11), which generates a detachment of deposited sediments and their dissolution in the water, which makes it easier for the suction pump to absorb the mixture of water and mud These suspended materials remain within the lower part of the perimeter of the system thanks to the anti-cloudiness mesh (14), which prevents that expand outside the perimeter of the device. This Platform works with a large capacity water pump (7) to work with high viscosity fluids. So that at no time does the suction pump come into direct contact with the surface of the sludge (12), which would prevent it from carrying out its work, a 'stopper' system with wheels (9) is used. This system consists of four vertical tubular profiles, placed in the lower part of the Medusa device, each of which contains a rotating wheel at the lower end. It is recommended that these profiles (including the wheel) measure between 0.6 and 1 meter in depth.The same wheels guarantee that the flow towards the suction pump remains free at all times, by keeping it away from the seabed at about 20 or 30 centimeters Optionally, a suction drawer (10) connected to the suction pump is used so that it can work in deeper areas.
