Definitions

  • the present invention is directed to an apparatus for the recovery of floating waste such as bottles, cans and bags, from waterways.
  • Microplastics are tiny pieces of plastic, usually less than 5 millimetres. According to a study by the European Parliament, according to their origin, they can be divided into two main categories: 1) primary microplastics, released directly into the environment in the form of small particles. It is estimated that this category of microplastics accounts for 15-31% of microplastics in the ocean. Their main source is synthetic garment washing (35% of primary microplastics), tyre abrasion while driving (28%), microplastics intentionally added in body care products (for example, facial scrub micro-particles, 2%). 2) Secondary microplastics, produced by the degradation of larger plastic objects, such as plastic bags, bottles or fishing nets.
  • CN 105621599 discloses a real dam to stop all objects floating on a river. This system has a significant aesthetic impact and presents the problem of requiring considerable maintenance. In fact, the dam blocks not only plastic objects, but also other objects such as branches, which would obstruct or block the dam.
  • US 2007/158253 discloses a mobile system for the collection of waste in the waters of rivers, lakes and seas.
  • the system is remarkably complex, therefore also expensive, and does not fit in small courses.
  • the present invention is directed to an apparatus for the removal of floating waste from rivers and watercourses in general, which includes a mouth to which a network is connected, which mouth has a fixing point positioned centrally that allows the mouth itself, and the whole apparatus, an oscillation. Thanks to this possibility of oscillation, large objects floating on the river (for example branches) do not remain in front of the mouth of the appliance but are able to slide over the appliance itself.
  • Figure 1 shows a frontal view of an apparatus 100 according to invention.
  • the figure shows round bars 110, 111, and 112 which form the mouth, buoys 120 for the flotation of the apparatus and coupling point 130, positioned centrally on the lower round bar 111, which allows the mouth to swing around the coupling point 130.
  • the device of figure 1 is suitable for fixing on the bottom of the watercourse, being the attachment point on the lower submerged bar 111. If it is intended to fix the appliance to an external element, it is necessary to place the attachment point on upper rod 110 of the mouth.
  • the diameter of the iron rods used to form the mouth of the appliance is between 6 and 10 mm. In the specific case, stainless steel rods of 6 mm diameter were used except for the lower 111 rod to which hook point 130 is fixed, which is 8 mm in diameter.
  • FIG. 2 shows a lateral view of the apparatus 100, showing the presence of 6 buoys 120 arranged vertically on both sides and at the centre of the lateral part.
  • the emerged part of the structure corresponds to about 40-60% of the total height of the structure itself. For example, if a mouth is 30 cm tall, the buoys should be sized so as to leave emerged about 12 to about 18 cm of the mouth. In this way, the emerged part of the solid waste will enter the mouth effortlessly.
  • this sizing allows to maintain a perfectly perpendicular position of the plane of the mouth with respect to the plane of the free surface of the water of the watercourse.
  • un modo di realizzacade preferito la rete e una rete di nylon avente preferibilmente una maglia compresa tra 20x20mm e 40x40 mm, ancor più preferibilmente 30x30 mm.
  • the net is a nylon net having preferably a mesh between 20x20mm and 40x40 mm, even more preferably about 30x30 mm.
  • the nylon thread guarantees a good mechanical resistance together with a good flexibility of the net itself, which facilitates the operations of emptying the collected objects.
  • the nylon thread has a thickness between 1,5 and 3 mm, preferably about 2 mm. In a preferred way, there are hooks 170 for opening the net in order to facilitate emptying of the device 100.
  • Figure 3 represents a top view of the apparatus 100 according to the preferred embodiment of Figure 1 . It has to be noted round bar 118 arranged centrally in a parallel direction to the mouth, which serves to increase the rigidity of the device when the length of the same exceeds 60 cm. In the way of realization shown in the figures, the apparatus has dimensions 100 cm (length) x 70 cm (mouth width) x 34 cm (height).
  • FIG 4 is a back view of the apparatus in which it is evidenced that also in the back there is a rectangular structure made with the side bars 115, upper bars 116 and lower bars 117.
  • Stabilising chains may be attached to the lower part of the mouth, and preferably of the net. In the case of the net, the presence of buoys and stabilising chains allows to keep the net in an extended position, facilitating the entry of objects collected by the apparatus.
  • the apparatus can be fixed to the river bed in various ways.
  • a type of fixation uses an external element to the river, such as a tree, a shore or a bridge.
  • the fixing device includes a fixing plate, connected to a fixing bar. At the end of the fixing bar there is a joint with an arm that reaches the central point of the mouth of the appliance. In this arm, there are preferably additional joints, which allow greater mobility in the watercourse to the apparatus, and a tensile spring to allow the extension of the arm in the presence of a tensile force.
  • the arm ends with an additional joint to which is attached a hook or anchor that allows the link of the mouth of the appliance. The length of the arm must take into account the variation of the level of the stream with the seasons.
  • the apparatus can be attached to the bottom of the watercourse by means of an anchor, fixed to a rock of adequate size, or anchored to a mooring "dead body" made according to the need.
  • the anchor is bound to the central joint of the mouth by a chain or rope.
  • the chain or rope must be of such a length as to allow the operation of the apparatus to vary the level of the watercourse, and the positioning of the "operating" structure is more upstream with a high level and more downstream with a low level.
