Description

Technical Field

[0001] The invention relates to a surface garbage collection ship, in particular to a surface garbage collection ship based on additive manufacturing. Background Art

[0002] With the rapid economic development, people's material living standards have greatly improved, and various types of waste generated by the public in daily life and production have increased accordingly. Some of the waste cannot be cleaned up and recycled in time and will flow into rivers, lakes and even oceans. Compared with land garbage, water surface garbage has stronger mobility, covers a wider area and is more difficult to recycle, resulting in the gradual severity of the water surface garbage problem, endangering the natural environment and human health. As the problem of surface garbage becomes more and more serious, people have gradually begun to pay attention to the recycling and treatment of surface garbage. At present, most of the recycling methods are manual fishing with scoop nets, which consumes a lot of manpower and material resources, is inefficient, and surface operations increase the safety risks of workers. With the popularization of intelligent machinery in all walks of life, some surface garbage recycling equipment has also been produced, but the current equipment still has some problems, such as the complex and bulky structure of the mechanical equipment, the limited or small working surface, the inability to change the working surface, and the inability to adapt to different areas of water. The recycling efficiency is low for large areas of water. Moreover, when sailing forward, the traditional equipment that uses conveyor belts and other garbage collection equipment will form shock waves between the hull and the front surface, making the garbage away from the collection ship and making it more difficult to collect. In addition to the garbage floating on the water, there is also a part of the garbage suspended under the water, which is difficult to be salvaged and collected. In summary, there is an urgent need for a device for collecting surface garbage that can replace manpower, improve garbage collection efficiency, and adapt to different water areas. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a surface garbage collection ship based on additive manufacturing, comprising a main hull and two sets of collection arms, the collection arms are long strips; the two sets of collection arms are respectively connected to the left and right sides of the front end of the main hull;

[0004] The main hull is provided with a control system, a power system and a collection box; the collection box has an opening in the front and drainage holes in the bottom and rear; the front end of the main hull is provided with an opening corresponding to the collection box; the collection box is semi-submersible, with the lower part under the water surface, and can collect garbage floating under the water surface, while keeping the garbage in the collection box floating, greatly reducing the weight of the hull;

[0005] The collecting arm comprises a shell, a floating body, a spiral blade shaft and a reduction motor. The outer side of the rear end of the shell is connected to the main hull through a double-axis steering gear, and the double-axis steering gear drives the collecting arm to open and close; the floating body is arranged at the front end of the shell; the spiral blade shaft is arranged in the shell, and both ends are pivotally connected to the shell; the reduction motor is arranged on the floating body, and the output shaft of the reduction motor is connected to one end of the spiral blade shaft; the reduction motor drives the spiral blade shaft to rotate, and the spiral blade shafts in the two groups of collecting arms rotate in opposite directions, forming a water flow flowing from the outside to the inside along the conveying direction of the spiral blade shaft, and the garbage on the water surface flows into the collection box along the direction of the water flow;

[0006] The power system, the dual-axis steering gear, and the reduction motor are respectively connected to the control system through control lines.

[0007] Furthermore, the collection box and spiral blade shaft are 3D printed with titanium alloy. The shaft of the spiral blade shaft is a hollow structure, which reduces weight and facilitates floating. Additive manufacturing is suitable for parts with more complex structures. Compared with other metals, titanium alloy has higher strength and toughness, and is resistant to pitting corrosion, acid corrosion, stress corrosion, and chlorides, which increases service life and reduces the weight of the hull.

[0008] The shell includes a support beam and an arc-shaped cover. The support beam is located on the outside of the collecting arm. The outer side of the arc-shaped cover is fixed to the support beam, and the inner side of the arc-shaped cover is higher than the outer side. When in water, the support beam of the shell is below the water surface, and the inner side is above the water surface. The width of the front end of the floating body is greater than the width of the rear end, and the inner side of the floating body is streamlined or arc-shaped, which is convenient for holding the water body and allowing the water flow to flow toward the main hull under the drive of the spiral blade shaft.

[0009] Furthermore, the left and right side walls of the front opening of the main hull are inclined from the outside to the inside, which is conducive to the water flow into the collection box and the full collection of surface garbage.

[0010] Furthermore, a plurality of drainage grooves are provided at the bottom of the main hull along the longitudinal direction of the hull from front to back, and the drainage grooves run through from the collecting box to the rear end of the main hull, and the plurality of drainage grooves are arranged in parallel.

[0011] Furthermore, the collection box is a dustpan-shaped box body, with openings on the front and top, and several drainage holes on the bottom and back; a flap is provided on the front opening of the collection box, and the upper part of the flap is pivotally connected to the collection box through a rotating shaft; blocks are provided on the left and right sides of the front opening of the collection box; the flap is located inside the block. When the boat is stationary, the flap naturally droops under the action of its own weight, blocking the garbage in the collection box and preventing the garbage from flowing out with the water flow; when the boat is moving forward, the flap will flip inwards under the impact of the water flow, and the water flow will enter the collection box.

[0012] Furthermore, the main hull is also provided with a communication system, a solar charging system and a battery. In the solar charging system, solar panels are arranged on the upper surface of the main hull; the battery is arranged inside the main hull; the solar charging system is connected to the battery to charge the battery; the battery is connected to the dual-axis steering gear, the reduction motor, the control system and the power system to provide electrical energy; the communication system is connected to the control system to realize remote communication and to realize information exchange with the on-land manual control console.

[0013] The power system is a propeller driven by a motor, which is arranged at the rear of the main hull and provides power for the main hull.

[0014] Furthermore, vision and radar modules are provided at the front end of the main hull and the front end of the floating bodies of the two sets of collecting arms. The vision and radar modules are connected to the control system through control lines and are used to collect images, obstacle information, etc., and transmit them to the control system for decision-making and control.

[0015] LED lights are also installed on the left and right sides of the vision and radar modules. The LED lights are connected to the control system and the battery respectively, controlled by the control system and powered by the battery. In darker environments, the LED lights on both sides can be turned on to illuminate the environment, thereby improving the working ability at night and on rainy days.

[0016] Working principle of the present invention:

[0017] In the initial state, the collection arms on both sides are brought together under the action of the dual-axis steering gear, and the control system controls the power system to drive the collection ship to sail to the designated operating waters to prepare for garbage collection;

[0018] After arriving at the designated operating waters, the dual-axis steering gears on both sides drive the collecting arms on both sides to open outwards, open to the appropriate angle according to the width of the waters, and sail forward driven by the power system; the control system controls the two reduction motors to drive the two spiral blade shafts to rotate, and the spiral blade shafts play a transmission role similar to that of an auger, transporting the water body in contact to the main hull in the middle. At the same time, the rotation of the spiral blade shaft causes a vortex to form in the surrounding waters, and larger floating objects and suspended matter below the water surface will flow into the collection box driven by the vortex; the garbage in the water flows into the collection box of the main hull with the water flow, and is collected after being filtered by the collection box.

[0019] After completing the garbage collection operation, the dual-axis servos on both sides drive the collection arms on both sides to close inward and sail back.

[0020] Beneficial effects of the present invention:

[0021] The present invention is different from the prior art in that the collecting arm adopts a spiral conveying structure, which can not only send small floating objects to the entrance of the collecting box, but also generate vortices that can drive larger floating objects to drift to the entrance of the collecting box. The collecting arm has an opening angle range of 0° to 180° to adapt to waters of different widths. When working, the arms are opened to increase the collection area per unit time. When not working, the arms are closed (0°) to reduce resistance and increase the moving speed. Different from the traditional method of using a conveyor belt to raise the surface garbage and send it into the collecting box, the present invention uses water flow to send floating objects into the collecting box. The semi-submerged dustpan-type collecting box allows the floating objects to remain floating in the box, greatly reducing the weight of the ship and increasing the garbage capacity. The spiral conveying structure can form a vortex on the water-facing surface of the collecting ship to flow toward the main hull, thereby improving the collection efficiency. The present invention can achieve the purpose of automatically cleaning garbage on the water surface by an unmanned collecting ship instead of manpower, greatly improving the efficiency of garbage cleaning, saving manpower, and reducing risks.
