Description

A floating garbage automatic collection device for shallow sea nearshore waters

Technical Field

The invention relates to an automatic floating garbage collecting device for shallow sea and offshore water areas.

Background

With the rise of ocean economy and the gradual improvement of environmental requirements of people, the problem of ocean pollution, particularly offshore pollution, is more and more widely concerned, but the treatment of the ocean pollution is quite complex due to the problems of wave motion, ocean boundaries and the like, and the current treatment policy and method are mainly based on controlling the input pollution of a fixed source on a drainage basin, for example, the current environmental management measures which are currently carried out in China such as the adoption of the emission standard of improving the land point source and the line source pollution are adopted; but basically has no effect on the pollution input by the non-fixed runoff and other natural and man-made factors, such as runoff, wind power, non-point source pollution caused by rainfall, travel, shipping pollution discharge and the like. Some countries adopt a power ship with low efficiency and high energy consumption to carry out manual dredging or mechanical dredging by a dredging ship, and some countries adopt a large-scale pipe/net for collection and dredging, which is very effective for short-time control of pollution under the condition of serious and relatively concentrated pollution, but has very low efficiency for pollution reduction under the condition of relatively dispersed floating garbage, complex terrain, not very large quantity of pollutants and long-term control.

Detailed Description

The invention will be further illustrated with reference to the following specific examples.

The invention relates to an automatic floating garbage collecting device for shallow sea and offshore water area, which mainly comprises an upper floating barrel 1 and a lower fixed barrel 2, wherein the upper part of the upper floating barrel is funnel-shaped for increasing buoyancy and stability, the edge of the upper floating barrel is provided with a rotary roller 3 to facilitate the flexible floating garbage to enter the upper floating barrel, and a fixed protrusion 4 is arranged in the funnel of the upper floating barrel 1 to prevent the floating objects entering the upper floating barrel 1 from moving outwards in the up-and-down movement process of the upper floating barrel 1; the mesh layer 5 on the one hand provides reinforcement and on the other hand prevents oversized floating objects from entering the lower part of the upper buoy 1. The lower part of the upper floating cylinder 1 is provided with a pair of rotatable valve 7 with a rotating shaft in the middle and a valve limiting ring 6.

The lower fixed cylinder 2 is movably sleeved outside the upper floating cylinder 1, and the maximum sliding distance between the upper floating cylinder 1 and the lower fixed cylinder 2 can be adjusted by a plurality of external limiting pull rods 10 for auxiliary positioning and adjusting nuts 11 on the limiting pull rods 10.

In order to increase the buoyancy of the lower fixed cylinder 2, the upper part of the lower fixed cylinder is provided with a closed hollow limiting box 9 which is fixed with the lower fixed cylinder 2 through spokes 8.

The lower part of the lower fixed cylinder 2 is provided with a grid layer 13, a bottom plate 12 of the lower fixed cylinder is provided with a one-way valve 14 and a fixed ring 15, and the fixed ring 15 is connected with a bottom fixed block 16 through a guy cable.

The working process of the invention is as follows: since the entire device is of a hollow structure and made of a low-density material, the device will be suspended in the sea water after installation. During installation, the length of a guy cable between a bottom fixed block 16 and a fixed ring 15 is adjusted according to the actual situation of an installation place, so that the wave crest of a typical wave just can be higher than the top of an upper floating cylinder 1, then a limit pull rod 10 is adjusted, so that the top of the upper floating cylinder 1 is lower than the wave crest of sea waves by about 10cm, when the upper floating cylinder is in the wave crest period (shown in figure 1), the upper floating cylinder 1 floats upwards under the action of buoyancy, a lower fixed cylinder 2 does not move, the volume of the whole device is increased, a rotatable valve 7 is opened downwards under the action of gravity and is static after contacting with a hollow limit box 9, at the moment, sea water and floating objects in the sea water enter the upper floating cylinder 1 and the lower fixed cylinder 2 under the action of gravity and negative pressure, and the top structure of the upper floating cylinder 1 is shown in a plan view 3; the device then enters a valley cycle as shown in fig. 2: the upper floating barrel descends along with the descending of the sea surface, the lower fixed barrel 2 is fixed under the action of buoyancy, the rotatable valve 7 is pushed by the hollow limiting box 9 to rotate upwards to be in contact with the valve limiting ring 6, the lower portion of the rotatable valve is led to form a sealed space, the upper floating barrel continues to descend, the space is compressed, liquid is discharged into seawater through the one-way valve 14 under the action of pressure, floating garbage is intercepted in the lower fixed barrel 2, the floating garbage operates in a reciprocating mode in such a period, the amount of floating garbage in the lower fixed barrel 2 is increased, and when the upper floating barrel 1 cannot descend to a designed position in a valley period, the floating objects in the lower fixed barrel need to be cleaned manually.

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
