Description

A self-priming sea drift garbage collection ship

technical field

The utility model relates to the technical field of marine environment cleaning, in particular to a self-suction type sea drift garbage collection ship.

Background technique

According to statistics published in the American journal Science published in 2015 by a research team from the University of Georgia, the global annual flow of plastic waste into the ocean ranges from 4.8 million to 12.7 million tons. The harm of marine garbage to natural organisms, human beings and the marine environment is manifold. A large amount of floating garbage not only causes serious marine pollution, damages the coast and beach landscape, hinders the normal navigation of ships, affects food safety, but also causes serious harm to marine life. At present, the damage caused by marine debris to marine life has reached an alarming level: at least 1 million seabirds and countless marine mammals are killed every year because of it. In addition, various bacteria, algae, tunicates, hydroids, and barnacles attached to marine drift garbage will be brought to all parts of the world as human-invading species and the toxic substances on them. Dealing with the flood of marine debris has become an international problem. For this reason, how to adopt appropriate methods to recycle marine floating garbage while reducing emissions has become a major issue in front of people.

For areas where floating garbage is scattered, the most widely used traditional sea-floating garbage cleaning method is generally manual boat cleaning, and crawler-type garbage collection ships are also used to clean areas where large-scale sea-floating garbage is accumulated. Artificial small boats are inefficient and unable to handle large areas of floating garbage, while crawler garbage collection ships consume too much energy to collect scattered floating garbage. In addition, the cleaning radius of existing garbage cleaning ships is relatively small, and they are not suitable for shallow water areas and narrow water areas near the shore where garbage is easy to accumulate and ships are difficult to approach.

At present, there are also automatic ocean floating garbage collection bins for marine garbage cleaning, which can be installed on the shore to collect floating garbage near the shore, or installed on the ship platform to clean up the floating belt that cannot be reached by the roadbed. The water pump is used to generate negative pressure, and the external garbage enters the garbage collection bin with the water flow to complete automatic collection. However, there are also problems. For shore-based installations, special ships are required to collect and transfer garbage on a regular basis. When installed on ship platforms, it is impossible to clean up shallow and narrow waters near the shore that are difficult for ships to approach.

Therefore, at this stage, there is an urgent need for a brand-new model of a special collection ship for sea drift garbage with comprehensive collection capabilities. Therefore, those skilled in the art are devoting themselves to developing a sea drift garbage collection ship with comprehensive collection capabilities.

Detailed ways

In order to further illustrate various embodiments, the utility model provides accompanying drawings. These drawings are part of the disclosure content of the present invention, which are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementations and advantages of the present utility model. Components in the figures are not drawn to scale, and similar component symbols are generally used to denote similar components.

The utility model is further described now in conjunction with accompanying drawing and specific embodiment.

As shown in FIG. 1 , this embodiment discloses a self-priming sea drift garbage collection ship, which includes: a hull 1 , a rotating shaft 3 , a mechanical arm 4 , and a collection device 6 . The collection device 6 is a negative pressure collection device, comprising a collection bucket 61 , a filter screen 62 and a water suction pipe 63 .

The rotating shaft 3 is fixedly installed on the hull 1 , the rotating shaft 3 is connected with the mechanical arm 4 , and one end of the mechanical arm 4 is connected with the collection barrel 61 . The mechanical arm 4 is a two-dimensional moving mechanical arm with stretchable parts and bendable parts. The maximum extendable length of the mechanical arm 4 determines the coverage area of garbage collection.

The water inlet of the water suction pipe 63 is positioned at the inside of the collection bucket 61 , and the water outlet of the water suction pipe 63 is connected to the water pump arranged on the hull 1 along the mechanical arm 4 .

As shown in Fig. 2 and Fig. 3, the collection bucket 61 is in the shape of a drum, the top is connected to the mechanical arm 4, the side wall or top surface of the collection bucket 61 and the junction of the side wall are provided with several collection ports 611, and a filter screen is installed at the bottom 62, the filter screen 62 can be opened from the bottom of the collection bucket 61, and the top center of the collection bucket 61 is connected to the mechanical arm 4. The water outlet of the suction pipe 62 is connected to the suction pump placed on the hull 1. The water suction pipe 62 extends to the collection bucket 61 along the mechanical arm 4. During operation, the water inlet of the suction port 5 does not produce air suction when it is submerged in the water. During operation, the collection bucket 61 is suspended in the water, and the collection port 611 is located at a critical position on the water surface. The water inlet of the suction pipe 62 is submerged in the water, and the suction pump provides power to form a negative pressure in the water inside the collection bucket 61, so that the floating garbage on the periphery can enter the collection bucket 61 through the collection opening 611 along with the water flow. The water sucked into the suction pipe 62 is discharged back into the river course or sea area by the water outlet of the water pump. A protective net cover 612 is installed between the water inlet of the suction pipe 62 and the collection port 611 to prevent garbage from entering and blocking the suction pipe 62 . The collection bucket 61 is proposed from the water after it is full of rubbish, and the water in the collection bucket 61 is discharged through the filter screen 62 . The filter screen 62 can be a net bag in the form of a wire rope net, a nylon net, or a steel wire mesh, and can also be a flat steel mesh plate.

In addition, the collection bucket 61 and the mechanical arm 4 can be softly connected, and the collection bucket 61 is equipped with a floating device, which can be suspended autonomously, so that the collection port 611 is always located at a critical position on the water surface.

As shown in FIG. 4 , after the collection bucket 61 is filled with garbage, under the joint action of the rotating shaft 3 as the mechanical arm 4 , it is lifted and rotated to the top of the recovery bin 7 of the hull 1 . The filter screen 62 is opened downwards, and the rubbish recovered by the collection barrel 61 is dumped into the recovery bin 7 . The filter screen 62 is closed subsequently, and the next operation can be carried out.

The mechanical arm 4 is driven by electricity or hydraulic pressure. Considering the stability of the smaller hull 1, the mechanical arm 4 can be arranged symmetrically on both sides of the hull 1 to work synchronously.

Although the utility model has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that, without departing from the spirit and scope of the utility model defined by the appended claims, changes in form and details may be made. Making various changes to the utility model is within the protection scope of the utility model.
