Description

Technical Field

[0001] The utility model relates to the technical field of intelligent control, and particularly relates to an unmanned cleaning ship. Background Art

[0002] With the acceleration of the urbanization process, urban water areas (such as lakes, rivers, canals and urban landscape water bodies), as an important part of the urban ecosystem, their water quality conditions are directly related to the living quality of residents and the health of the urban ecological environment. However, urban water areas are facing increasingly severe water pollution problems, including domestic sewage discharge, industrial wastewater leakage, pollutants carried by rainwater runoff, and overgrowth of aquatic plants, etc., which all put higher requirements on the cleaning and maintenance of water areas.

[0003] Traditionally, the cleaning work of urban water areas mainly relies on small boats or shore-based equipment operated manually, which is not only inefficient, but also difficult to cover large water areas. Especially in complex terrains or bad weather conditions, the operation difficulty and danger increase significantly. In addition, manual cleaning also has problems such as high cost, large labor intensity, and difficulty in continuously monitoring water quality changes.

[0004] In recent years, with the rapid development of unmanned technology, intelligent control, Internet of Things and sensor technology, intelligent cleaning unmanned ships have gradually become a new way to solve the problem of urban water area cleaning. There have been some relevant researches and applications at home and abroad. For example, unmanned ships using technologies such as GPS navigation, automatic obstacle avoidance, and water quality monitoring sensors have realized automatic cruising and preliminary cleaning operations for specific water areas. However, these existing technologies still have some deficiencies.

[0005] For example, in the existing single-hull ship type design, its hull is relatively wide, resulting in a relatively large viscous pressure difference resistance (eddy current resistance), and the bow shape is not conducive to reducing the wave-making resistance. As the ship speed increases, the wave-making resistance increases significantly, affecting the navigation efficiency and stability, with obvious ship waves, which is not conducive to environmental protection and navigation safety, and limits the increase of the ship speed.

[0046] Embodiment

[0047] This embodiment provides an unmanned cleaning ship, as Figure 1 and Figure 2 shown, including a hull 1, a propeller 2, a garbage basket 3, a salvage assembly 4, and a barrier net 5.

[0048] In this embodiment, the number of hulls 1 is two, the two hulls 1 are arranged in parallel, the two hulls 1 are connected to each other and a placement space is formed between the two hulls 1; the front end of any one hull 1 is in a pointed shape; the thruster 2 is connected to the ends of the two hulls 1; the trash basket 3 is located in the placement space and is connected to the hull 1; the fishing assembly 4 is connected to the hull 1, the front end of the fishing assembly 4 is at the bottom side of the hull 1, and the end of the fishing assembly 4 is at the upper side of the trash basket 3.

[0049] The catamaran adopts a more slender hull design, which helps to reduce the viscous pressure difference resistance (eddy resistance) suffered by the hull 1 during navigation; the front part of the catamaran hull adopts a pointed water-breaking design, which can reduce the wave-making resistance generated by the hull 1 during navigation and at the same time reduce the ship waves, making the ship more stable; due to the reduction of the wave-making resistance and the eddy resistance, the catamaran shows higher stability and efficiency during low-speed navigation, which is beneficial for long-term and continuous surface garbage cleaning operations.

[0050] In this embodiment, the number of the barrier nets 5 is two, and the rear ends of the two barrier nets 5 are respectively connected to the front end of one hull 1; the two barrier nets 5 extend out of the front end of the hull 1 and form a blocking space between the two barrier nets 5, and the front end of the fishing assembly 4 is located in the blocking space.

[0051] Furthermore, the two barrier nets 5 are distributed in a "V" shape, and the opening at the front end of the two barrier nets 5 is larger than the opening at the rear end of the two barrier nets 5.

[0052] Furthermore, the rear ends of the two barrier nets 5 are both hinged to the hull 1; the unmanned cleaning ship further includes a pushing member 6, one end of the pushing member 6 is connected to the hull 1, and the other end of the pushing member 6 is connected to the barrier net 5; the pushing member 6 is configured to push the barrier net 5 to rotate relative to the hull 1. Preferably, the pushing member 6 is an electric push rod.

[0053] The garbage gathering device adopts two barrier nets 5, and uses an electric push rod to control the opening and closing of the barrier nets 5 and guide the floating garbage into the placement space of the hull 1, which can effectively gather the floating garbage into the fishing range of the fishing assembly 4 to improve the garbage collection efficiency.

[0054] In this embodiment, as Figure 1 shown, in order to prevent the front ends of the barrier nets 5 from hitting buildings such as river banks and causing damage to the barrier nets 5, rollers are provided at the front ends of the two barrier nets 5.

[0055] In this embodiment, as Figure 1 shown, the two flow guiding plates 7 are respectively connected to the pointed front end, and the flow guiding plates 7 are located inside the pointed front end.

[0056] In this embodiment, the salvage assembly 4 includes a bracket 41, two sprockets 42, a salvage plate 43, a reduction motor 44, a sprocket tensioning device 45, and a coupling. The bracket 41 is arranged in the placement space and is connected to the two hulls 1. The two sprockets 42 are respectively rotatably connected to the bracket 41 and are respectively arranged at both ends of the bracket 41. A chain is engaged with the two sprockets 42. A number of salvage plates 43 are connected to the chain and move synchronously with the chain. The reduction motor 44 is connected to one sprocket 42. The sprocket tensioning device 45 is connected to the bracket 41. The coupling is arranged between the reduction motor 44 and the sprocket 42.

[0057] The reduction motor 44 transmits the rotary motion and torque to the sprocket 42 through the coupling, shaft, and key. The sprocket 42 drives the double-bend plate single-hole chain. The chain plates adapted to the chain and the salvage plate 43 are connected to the threaded holes of the chain by bolts. The chain drives the salvage plate 43 to move and convey the floating garbage to a high place. The garbage falls into the garbage basket 3 under the action of gravity. The salvage plate 43 is mainly used to prevent the garbage with a smooth surface from slipping off the chain plate. When the garbage basket 3 is full of garbage, the unmanned boat returns to the shore and the garbage basket can be easily loaded.

[0058] The salvage plate 43 conveys the floating garbage into the garbage basket 3 under the drive of the chain. Due to the certain inclination angle of the conveying chain, the salvage plate 43 can prevent the garbage with a smooth surface from slipping. The overall shape of the salvage plate 43 is L-shaped and is manufactured by the sheet metal bending method. Through holes are arranged on the salvage plate 43 for installing bolts to connect the chain link and the salvage plate 43. Drainage holes are designed on the salvage plate 43 to filter out the moisture of the garbage during the process of conveying the garbage and prevent overload. The garbage basket 3 stores the garbage and is manufactured by the sheet metal bending method. Drainage holes are designed at the bottom of the garbage basket to filter out the excess moisture. Handles are welded on both sides of the garbage basket for easy loading and unloading of the garbage.

[0059] When the sag of the loose side of the chain is too large, the chain is prone to poor meshing, severe vibration, tooth skipping, and tooth disengagement. The solution is to tension it. Common tensioning methods include adjusting the center distance between the sprockets 42, setting a tensioning wheel or a supporting plate. Due to the limited space and buoyancy of the catamaran, setting a tensioning wheel or a supporting plate has disadvantages such as occupying space, being difficult to install, and increasing weight. Therefore, the method of adjusting the center distance between the sprockets 42 is adopted. By turning the adjusting rod bolt of the sprocket tensioning device 45, the translation of the sprocket 42 shaft is realized, and then the center distance of the shaft is adjusted to realize the tensioning of the sprocket 42. Among them, the sprocket tensioning device 45 can adopt the existing structure in the prior art. In this embodiment, it is directly applied, so its principle will not be elaborated here too much.

[0060] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the creation of the present utility model.
