Description

Technical Field

[0001] The invention relates to the technical field of garbage salvage ships, in particular to an unmanned garbage salvage ship used for garbage treatment in water areas. Background Art

[0002] As an important part of modern environmental protection equipment, garbage salvage ships are increasingly becoming a key force in cleaning waters and maintaining ecological balance. They not only greatly alleviate water pollution problems by efficiently and accurately cleaning floating garbage on the water surface, such as plastic waste and domestic garbage, but also improve water quality and provide a healthier living environment for aquatic organisms, thereby promoting the virtuous cycle of the entire ecosystem.

[0003] The garbage salvage ship industry has broad development prospects. However, there are still many problems with garbage salvage ships. The conveyor belt of the garbage salvage ship is prone to stains and oil after long-term work. If it is not cleaned for a long time, the attachments will gradually corrode the conveyor belt. At the same time, too many attachments will reduce the conveying efficiency of the conveyor belt. Traditional manual inspection and maintenance not only consumes human resources, but also does not conform to the current development trend of unmanned salvage ships. Summary of the invention

[0004] The purpose of the present invention is to provide an unmanned garbage salvaging vessel for garbage disposal in water areas to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an unmanned garbage salvage ship for garbage disposal in water areas, comprising an unmanned hull, a collection cabin installed on the unmanned hull, an electric conveyor belt installed on the unmanned hull, a base plate installed on the unmanned hull through a bracket, a cleaning device and an electric lifting platform installed on the base plate, a detection and maintenance device installed on the electric lifting platform, a dirt collecting plate rotatably installed at the end of the unmanned hull, and a plurality of conveying plates are provided on the electric conveyor belt.

[0006] A control system is installed inside the unmanned hull, which is used to control the operation of the entire unmanned garbage salvage ship. One end of the electric conveyor belt is located below the water level. A number of high-pressure nozzles are installed on the cleaning device, which draw water from under the water surface of the water area through an external water supply device and input it into the cleaning device. Water is sprayed out from the high-pressure nozzles to perform high-pressure water washing on the electric conveyor belt.

[0007] The control system controls the unmanned boat to travel to the waters that need to be salvaged. While traveling, the unmanned boat will push the garbage forward and cooperate with the sewage collecting plates on both sides to gather the garbage to the middle. The control system turns on the electric conveyor belt. Since one end of the electric conveyor belt is below the water level, when the electric conveyor belt rotates, the transmission plate on the electric conveyor belt will lift the garbage on the water surface from the bottom of the water, so that the garbage follows the rotation of the electric conveyor belt and goes up. When the garbage taken away from the water surface follows the electric conveyor belt to the collection bin position, it falls into the collection bin as the electric conveyor belt turns. Afterwards, the control system intermittently turns on the cleaning device according to the preset interval time to regularly clean the electric conveyor belt. According to the number of cleaning times, the control system intermittently turns on the detection and maintenance device.

[0008] The detection and maintenance device includes a transmission base plate, a detection and maintenance component and an output motor. Rotating connecting parts are symmetrically installed at both ends of the transmission base plate, rack plates are installed on both sides of the transmission base plate, slide rails are provided on both sides of the transmission base plate, the output shaft of the output motor passes through the rotating connecting part and is installed with a lead screw, both ends of the lead screw are rotatably connected to the rotating connecting part, the lead screw is provided with threads, the transmission base plate is slidably connected to the detection and maintenance component through the slide rail, and the detection and maintenance component is threadedly connected to the lead screw.

[0009] The control system controls the rotation of the electric conveyor belt. When the conveyor plate is aligned with the two detection rollers, the electric conveyor belt is stopped, and the control system starts the electric lifting platform. The electric lifting platform drives the detection and maintenance device onto the platform until the oil detection plate fits the surface of the electric transmission belt. Then the output motor is started, and the output shaft of the output motor drives the lead screw to rotate, and the lead screw drives the detection and maintenance assembly to rotate. Since the sliding base is slidably connected to the transmission base plate through the first slide groove and the slide rail, the detection and maintenance assembly converts the rotation into a linear sliding along the transmission base plate.

[0010] The detection and maintenance component includes a sliding base, a first sliding groove is provided on the sliding base, slideways are symmetrically provided on the sliding base, a threaded hole is provided on the sliding base, the sliding base is slidably connected to the slide rail through the first sliding groove, the sliding base is threadedly connected to the lead screw through the threaded hole, a detector is slidably installed on the sliding base through the slide, a brushing component is installed on the sliding base, and a transmission component is installed on the sliding base; the transmission component includes a first electric telescopic rod and a rotating rod connecting piece, the first electric telescopic rod is installed on the sliding base, the output shaft of the first electric telescopic rod is rotatably installed with a transmission rotating rod through the rotating rod connecting piece, transmission gears are symmetrically installed on both sides of the transmission rotating rod, and the transmission gears are meshed with the rack plate for transmission.

[0011] The sliding base slides at a uniform speed along the end of the screw rod away from the output motor to the end close to the output motor. When sliding to the position of the conveying plate, the detection roller is tightly fitted with both sides of the conveying plate under the action of the second spring.

[0012] The brushing assembly includes a brushing connecting piece, which is installed on a sliding base. A first slider is slidably installed in the brushing connecting piece. A first spring is installed between the first slider and the brushing connecting piece. A cleaning rotating rod is rotatably installed between the first sliders. A brush wheel is installed on the cleaning rotating rod, and a rotating gear is installed on one side of the brush wheel.

[0013] The brush wheel is provided with a water outlet hole which runs through inside and outside, and the surface of the brush wheel is provided with bristles. The brush wheel is externally connected with a water supply device which delivers high-pressure cleaning liquid to the inside of the brush wheel. The cleaning liquid is sprayed out from the water outlet hole and cooperates with the bristles to brush and spray the surface of the electric conveyor belt.

[0014] When oil is detected on the surface of the electric conveyor belt, the control system starts the first electric telescopic rod, and the output shaft of the first electric telescopic rod drives the transmission rotating rod to retract through the rotating rod connecting piece, and the transmission rotating rod drives the transmission gears on both sides to retract, and the transmission gear rolls on the rack plate and moves toward the rotating gear. When the transmission gear is engaged with the rotating gear, the first electric telescopic rod further retracts, and the transmission gear continues to move and lifts the rotating gear. The rotating gear drives the cleaning rotating rod to slide upward in the groove on the brush connecting piece until the first spring is completely compressed. At this time, the cleaning rotating rod drives the brush wheel to be lifted to the highest point, so that the brush wheel can fully brush the surface of the electric conveyor belt when it rotates. Afterwards, the control system makes the driving motor rotate in the opposite direction, and the detection and maintenance component slides along the lead screw from the end close to the output motor to the end away from the output motor. When sliding, the transmission gear moves and rotates on the gear bar, and the transmission gear drives the rotating gear to rotate, and the rotating gear drives the brush wheel to rotate. The rotation of the brush wheel brushes the surface of the electric conveyor belt, and the sliding base slides to make the brush wheel slide and brush at the same time, and the horizontal scraper scrapes off the stains remaining on the surface of the electric conveyor belt, thereby achieving cleaning and maintenance of the surface of the electric transmission belt.

[0015] The detector includes a detection substrate, wing plates are provided on both sides of the detection substrate, a second slide groove is provided on the wing plate, a third slide groove is symmetrically provided on the detection substrate, and sliding holes are symmetrically provided on the detection substrate. A friction detection component is slidably installed in the third slide groove, and a stain detection component is slidably installed in the sliding hole. A second electric telescopic rod is installed on the wing plate, and an oil detection plate is installed on the second electric telescopic output shaft. The oil detection plate is slidably connected to the second slide groove, the oil detection plate is slidably connected to the wing plate, the friction detection component is slidably connected to the slide, and the stain detection component is slidably connected to the oil detection plate.

[0016] The friction detection component includes a second slider, a second piezoelectric element and a second force transmission plate. The second slider is slidably installed in the third slide groove. A fourth spring is installed between the second slider and the detection substrate. A T-shaped slide bar is installed on the second slider. One end of the T-shaped slide bar is slidably connected to the slide. The second force transmission plate is slidably installed in the slide. The second piezoelectric element is installed in the slide. A third spring is installed between the second force transmission plate and the T-shaped bar.

[0017] The stain detection component includes a detection slide rod, a first piezoelectric element and a first force transmission plate. One end of the detection slide rod is slidably connected to the sliding hole, and the other end of the detection slide rod is installed with a measuring wheel connecting piece, and a detection roller is rotatably installed on the measuring wheel connecting piece. The first piezoelectric element is installed on the detection substrate, and the detection slide rod passes through the first piezoelectric element. The first force transmission plate is slidably installed on the detection slide rod, and a second spring is installed between the first force transmission plate and the measuring wheel connecting piece. The measuring wheel connecting piece is slidably connected to the oil stain detection plate.

[0018] When stains are attached to both sides of the conveying plate, bulges will appear on the surface of the conveying plate. When the detection roller rolls over the stained surface, it will drive the detection slide bar to retract through the measuring wheel connecting piece. When the measuring wheel connecting piece retracts, it drives the second spring to be compressed. After the second spring is compressed, the elastic force on the first force transmission plate increases. When the elastic force is transmitted to the first piezoelectric element through the first force transmission plate, the first piezoelectric element is compressed to generate electric charge. The charge flows to the control system through the wire. The control system can analyze the size of the stain on the surface of the transmission plate through the strength of the electrical signal, and can analyze the position of the stain on the conveying plate according to the changing time of the electrical signal, thereby realizing automatic detection of stains on the surface of the conveying plate.

[0019] When stains are detected on the transmission plate, the control system turns on the second electric telescopic rod, and the output shaft of the second electric telescopic rod drives the oil stain detection plate to slide, so that the two oil stain detection plates are close to each other until the vertical scraper can fit with both sides of the conveyor plate when passing through the conveyor plate. When the sliding base drives the oil stain detection plate to slide, the chamfers on the vertical slides scrape off the stains on both sides of the conveyor plate, thereby realizing the inspection and maintenance of the conveyor plate. After cleaning, turn on the inspection and maintenance device again, and repeat the above operations until the inspection is qualified. When the cleanliness of the electric transmission belt and the conveyor plate is always unqualified and the inspection data no longer changes, it proves that the surface of the electric transmission shell and the conveyor plate is damaged or has other special conditions, and the control system controls the unmanned garbage salvage ship to return for maintenance and inspection.

[0020] A sliding connector is provided on the oil detection plate, a horizontal scraper is provided on the oil detection plate, a vertical scraper is provided on the oil detection plate, both the horizontal scraper and the vertical scraper are provided with chamfers, a rounded corner is provided on the oil detection plate, a measuring wheel groove is provided on the oil detection plate, the oil detection plate is slidingly connected to the measuring wheel connector through the measuring wheel groove, and the oil detection plate is connected to the output shaft of the second electric telescopic rod through the sliding connector.

[0021] The rounded corners make it easier for the oil detection plate to pass quickly when it encounters attached stains; the chamfers on the horizontal and vertical scraping strips enable both to scrape off the stains.

[0022] The sliding base slides and pushes the oil stain detection plate to slide along the surface of the electric conveyor belt through the T-shaped slide bar. The top surface of the oil stain detection plate and the surface of the electric conveyor belt generate friction. Under the action of the friction, the oil stain detection plate slides relative to the sliding base. The oil stain detection plate drives the T-shaped slide bar to slide and retract along the slideway through the second slider. The T-shaped bar retracts and compresses the third spring. After the third spring is compressed, the elastic force on the second force transmission plate increases. The second force transmission plate transmits the elastic force to the second piezoelectric element. The second piezoelectric element is compressed to generate electric charge. The charge is transmitted to the control system through the wire. The control system analyzes the change in friction between the top surface of the oil stain detection plate and the surface of the electric conveyor belt according to the change in the electrical signal, and judges whether there is still oil stain attached to the surface of the electric conveyor belt according to the change amount. When the surface of the electric conveyor belt is clean, the friction between the top surface of the oil detection plate and the surface of the electric conveyor belt is relatively constant; when oil appears on the surface of the electric conveyor belt, the friction decreases and the electrical signal becomes smaller; when there are stains on the surface of the electric conveyor belt, the oil detection plate will drive the detection substrate to slide downward through the third slide groove when passing through the stains, so as to quickly pass through the stains. At the same time, the resistance brought by the stains to the oil detection plate will cause the T-shaped slide bar to retract quickly in a short time, causing a sudden change in the electrical signal. The control system determines whether there are stains attached to the electric conveyor belt based on the sudden change in the electrical signal; when the detection roller is affected by the resistance of the stain and is transmitted to the oil detection plate through the detection substrate, the control system combines the electrical signal of the second piezoelectric element. When the first piezoelectric element and the second piezoelectric element change at the same time, it proves that the detection roller causes the first piezoelectric element to produce an electrical signal change, thereby eliminating the possibility of stains on the surface of the electric conveyor belt.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. Use the cleaning device to regularly clean the electric conveyor belt and conveyor plate to prevent garbage and oil from adhering for a long time, affecting the salvage efficiency and causing corrosion and damage to the electric conveyor belt and conveyor plate.

[0024] 2. Use the oil stain detection board to convert the oil stain on the surface of the electric conveyor belt into friction, and then convert the friction into electrical signals for identification. By identifying the strength of the electrical signals, the adhesion of the oil stains can be detected. At the same time, the stain adhesion on the surface of the electric conveyor belt can be converted into a sudden electrical signal. By identifying the electrical signals, the stains on the surface of the conveyor belt can be detected. The stains on the surface of the electric conveyor belt and the conveyor plate can be scraped off by the horizontal and vertical scraping strips on the oil stain detection board.

[0025] 3. Use the stain detection component to convert the adhesion of the stain into the displacement of the detection roller, and then convert the displacement into a recognizable electrical signal. By analyzing the strength and change time of the electrical signal, automatic detection of stains on the surface of the conveyor plate can be achieved.

[0026] 4. The transmission assembly is used to drive the brush assembly to automatically rise and fall, and the rack plate is used to drive the transmission assembly to rotate. No additional drive is required. The transmission assembly drives the brush wheel to rotate, thereby achieving cleaning and maintenance of the surface of the electric transmission belt.

[0027] 5. Use the output motor to drive the detection and maintenance components to move at a uniform and stable speed through the screw rod to ensure stability during the detection process. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The working principle of the present invention is as follows: the control system controls the unmanned boat 5 to travel to the water area that needs to be salvaged. When traveling, the unmanned boat 5 will push the garbage forward and cooperate with the sewage collecting plates 2 on both sides to gather the garbage to the middle. The control system turns on the electric conveyor belt 3. Since one end of the electric conveyor belt 3 is below the water level, when the electric conveyor belt 3 rotates, the transmission plate on the electric conveyor belt 3 will hold up the garbage on the water surface from the bottom of the water, so that the garbage rotates with the electric conveyor belt 3 and goes up. When the garbage taken away from the water surface follows the electric conveyor belt 3 to the position of the collection bin 1, it falls into the collection bin 1 as the electric conveyor belt 3 turns. Afterwards, the control system intermittently turns on the cleaning device 7 according to the preset interval time to regularly clean the electric conveyor belt 3. According to the number of cleaning times, the control system intermittently turns on the detection and maintenance device 8.

[0043] The control system controls the electric conveyor belt 3 to rotate. When the conveyor plate is aligned with the two detection rollers 8653, the electric conveyor belt 3 is stopped. The control system starts the electric lifting platform 6, and the electric lifting platform 6 drives the detection and maintenance device 8 to go up until the oil detection plate 862 is in contact with the surface of the electric transmission belt. Then the output motor 81 is started, and the output shaft of the output motor 81 drives the screw rod 83 to rotate, and the screw rod 83 drives the detection and maintenance assembly 84 to rotate. Since the sliding base 87 is slidably connected to the transmission base plate 82 through the first slide groove 871 and the slide rail 822, the detection and maintenance assembly 84 converts the rotation into a linear sliding along the transmission base plate 82.

[0044] The sliding base 87 slides at a constant speed along the end of the screw rod 83 away from the output motor 81 to the end close to the output motor 81. When sliding to the position of the conveying plate 31, the detection roller 8653 fits tightly with both sides of the conveying plate 31 under the action of the second spring 8652.

[0045] When stains are attached to both sides of the conveying plate 31, bulges will appear on the surface of the conveying plate 31. When the detection roller 8653 rolls over the stain surface, it will drive the detection slide bar 8651 to retract through the measuring wheel connecting piece 8654. When the measuring wheel connecting piece 8654 retracts, it will drive the second spring 8652 to be compressed. After the second spring 8652 is compressed, the elastic force on the first force transmission plate 8655 increases. When the elastic force is transmitted to the first piezoelectric element 8656 through the first force transmission plate 8655, the first piezoelectric element 8656 is compressed to generate electric charge. The charge flows to the control system through the wire. The control system can analyze the size of the stain on the surface of the transmission plate through the strength of the electrical signal, and can analyze the position of the stain on the conveying plate 31 according to the change time of the electrical signal, thereby realizing automatic detection of stains on the surface of the conveying plate 31.

[0046] The sliding base 87 slides and pushes the oil stain detection plate 862 to slide along the surface of the electric conveyor belt 3 through the T-shaped slide bar 8641. The top surface of the oil stain detection plate 862 generates friction with the surface of the electric conveyor belt 3. Under the action of the friction, the oil stain detection plate 862 slides relative to the sliding base 87. The oil stain detection plate 862 drives the T-shaped slide bar 8641 to slide and retract along the slideway 873 through the second slider 8646. The T-shaped bar retracts and compresses the third spring 8644. After the third spring 8644 is compressed, the elastic force on the second force transmission plate 8642 increases. The second force transmission plate 8642 transmits the elastic force to the second piezoelectric element 8643. The second piezoelectric element 8643 generates electric charge when compressed. The electric charge is transmitted to the control system through the wire. The control system analyzes the change in the friction between the top surface of the oil stain detection plate 862 and the surface of the electric conveyor belt 3 according to the change in the electrical signal, and judges whether there is still oil stain attached to the surface of the electric conveyor belt 3 according to the change. When the surface of the electric conveyor belt 3 is clean, the friction between the top surface of the oil stain detection plate 862 and the surface of the electric conveyor belt 3 is relatively constant; when oil stains appear on the surface of the electric conveyor belt 3, the friction decreases and the electrical signal becomes smaller; when stains are adhered to the surface of the electric conveyor belt 3, the oil stain detection plate 862 will drive the detection substrate 863 to slide downward through the third slide groove 8633 when passing through the stains, thereby quickly passing through the stains. At the same time, the resistance brought by the stains to the oil stain detection plate 862 will cause the T-shaped slide bar 8641 to retract quickly in a short time, so that the electric conveyor belt 3 can be moved. The signal produces a sudden change, and the control system determines whether there is stain attached to the electric conveyor belt 3 based on the sudden change of the electrical signal; when the detection roller 8653 is affected by the resistance of the stain and transmits it to the oil detection plate 862 through the detection substrate 863, the control system combines the electrical signal of the second piezoelectric element 8643. When the first piezoelectric element 8656 and the second piezoelectric element 8643 change at the same time, it proves that the detection roller 8653 causes the first piezoelectric element 8656 to produce an electrical signal change, thereby eliminating the possibility of stains on the surface of the electric conveyor belt 3.

[0047] When oil is detected on the surface of the electric conveyor belt 3, the control system starts the first electric telescopic rod 884, and the output shaft of the first electric telescopic rod 884 drives the transmission rotating rod 882 to retract through the rotating rod connecting piece 883, and the transmission rotating rod 882 drives the transmission gears 881 on both sides to retract, and the transmission gear 881 rolls on the rack plate 823 and moves toward the rotating gear 853. When the transmission gear 881 is engaged with the rotating gear 853, the first electric telescopic rod 884 further retracts, and the transmission gear 881 continues to move and lifts the rotating gear 853. The rotating gear 853 drives the cleaning rotating rod 856 to slide upward in the groove on the brush connecting piece 852 until the first spring 855 is completely compressed. At this time, the cleaning rotating rod 856 drives the brush wheel 851 to be lifted to the highest point, so that the brush wheel 851 can fully brush the surface of the electric conveyor belt 3 when it rotates. Afterwards, the control system makes the driving motor rotate in the opposite direction, and the detection and maintenance component 84 slides along the screw rod 83 from the end close to the output motor 81 to the end away from the output motor 81. When sliding, the transmission gear 881 moves and rotates on the gear bar plate, and the transmission gear 881 drives the rotating gear 853 to rotate, and the rotating gear 853 drives the brush wheel 851 to rotate. The brush wheel 851 rotates to brush the surface of the electric conveyor belt 3, and the sliding base 87 slides to make the brush wheel 851 slide and brush at the same time, and the horizontal scraper 8621 scrapes off the stains remaining on the surface of the electric conveyor belt 3, thereby realizing the cleaning and maintenance of the surface of the electric transmission belt.

[0048] When stains are detected on the transmission plate, the control system turns on the second electric telescopic rod 861, and the output shaft of the second electric telescopic rod drives the oil stain detection plate 862 to slide, so that the two oil stain detection plates 862 are close to each other, until the vertical scraper 8625 can fit the two sides of the conveying plate 31 when passing through the conveying plate 31. When the sliding base 87 drives the oil stain detection plate 862 to slide, the chamfers on the vertical slides scrape the stains on both sides of the conveying plate 31, thereby realizing the inspection and maintenance of the conveying plate 31. After cleaning, the inspection and maintenance device 8 is turned on again, and the above operation is repeated until the inspection is qualified. When the cleanliness of the electric transmission belt and the conveying plate 31 is always unqualified and the inspection data no longer changes, it proves that the surface of the electric transmission shell and the conveying plate 31 is damaged or has other special conditions, and the control system controls the unmanned garbage salvage ship to return for maintenance and inspection.
