Abstract

This invention discloses an unmanned garbage retrieval vessel for waterborne garbage disposal, belonging to the field of garbage retrieval vessel technology. It includes a collection bin, a sludge collection plate, an electric conveyor belt, a base plate, an unmanned hull, an electric lifting platform, a cleaning device, and a detection and maintenance device. The invention utilizes the cleaning device to regularly clean the electric conveyor belt and conveyor plate, preventing garbage and oil stains from adhering for extended periods, thus affecting retrieval efficiency and causing corrosion and damage to the electric conveyor belt and conveyor plate. An oil stain detection plate converts the oil stains on the surface of the electric conveyor belt into frictional force, which is then converted into an electrical signal for identification. By identifying the strength of the electrical signal, the degree of oil stain adhesion is detected. Simultaneously, the adhesion of dirt on the surface of the electric conveyor belt is converted into abrupt electrical signals, thereby achieving the detection of dirt on the conveyor belt surface. Horizontal and vertical scrapers on the oil stain detection plate scrape away dirt from the surface of the electric conveyor belt and conveyor plate.

Description

Technical Field

[0001] This invention relates to the field of garbage retrieval vessel technology, specifically an unmanned garbage retrieval vessel for waterborne garbage disposal. Background Technology

[0002] As an important component of modern environmental protection equipment, garbage collection vessels are increasingly becoming a key force in cleaning up waterways and maintaining ecological balance. They not only greatly alleviate water pollution by efficiently and precisely cleaning up floating garbage such as plastic waste and household waste, but also improve water quality, providing a healthier living environment for aquatic organisms and thus promoting a virtuous cycle of the entire ecosystem.

[0003] The garbage retrieval vessel industry has broad development prospects. However, there are still many problems with garbage retrieval vessels. After long-term operation, the conveyor belts of garbage retrieval vessels are prone to accumulating dirt and oil. If they are not cleaned for a long time, the deposits will gradually corrode the conveyor belts. At the same time, too much deposits will reduce the conveyor belt's efficiency. Traditional manual inspection and maintenance not only consume human resources but also does not conform to the current trend of unmanned development of retrieval vessels. Summary of the Invention

[0004] The purpose of this invention is to provide an unmanned garbage collection vessel for waterborne garbage disposal, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an unmanned garbage collection vessel for water area garbage disposal, comprising an unmanned hull, a collection compartment installed on the unmanned hull, an electric conveyor belt installed on the unmanned hull, a base plate installed on the unmanned hull via 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 sludge collection plate rotatably installed at the end of the unmanned hull, and a plurality of conveying plates provided on the electric conveyor belt.

[0006] The unmanned vessel is equipped with a control system that controls the operation of the entire unmanned garbage collection vessel. One end of the electric conveyor belt is located below the water level. The cleaning device is equipped with several high-pressure nozzles. Water below the water surface is drawn from the water supply device and fed into the cleaning device. The water is sprayed out from the high-pressure nozzles to perform high-pressure water washing on the electric conveyor belt.

[0007] The control system guides the unmanned vessel to the area requiring retrieval. During this movement, the vessel propels the debris forward, and the collection plates on both sides help gather the debris towards the center. The control system then activates the electric conveyor belt. Since one end of the conveyor belt is below the water level, as it rotates, the transport plates on the belt lift the debris from the bottom of the water, causing it to rise with the belt. The debris, lifted off the water, falls into the collection bin as the conveyor belt turns. Afterward, the control system intermittently activates the cleaning device at preset intervals to clean the electric conveyor belt. Based on the number of cleaning cycles, the control system also intermittently activates the detection and maintenance device.

[0008] The inspection and maintenance device includes a transmission base plate, an inspection and maintenance component, and an output motor. Rotary 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, and slide rails are provided on both sides of the transmission base plate. The output shaft of the output motor passes through the rotary connecting parts and is equipped with a lead screw. Both ends of the lead screw are rotatably connected to the rotary connecting parts, and the lead screw is threaded. The transmission base plate is slidably connected to the inspection and maintenance component through the slide rails, and the inspection 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 stops, and the control system starts the electric lifting platform. The electric lifting platform lifts the detection and maintenance device onto the platform until the oil stain detection plate is in contact with the surface of the electric conveyor belt. Then, the output motor is started, and the output shaft of the output motor drives the lead screw to rotate. The lead screw drives the detection and maintenance component to rotate. Since the sliding base and the transmission base plate are slidably connected through the first slide groove and the slide rail, the detection and maintenance component converts the rotation into linear sliding along the transmission base plate.

[0010] The inspection and maintenance component includes a sliding base with a first slide groove, symmetrical slide rails, and threaded holes. The sliding base is slidably connected to a slide rail via the first slide groove and threaded to a lead screw via the threaded holes. A detector is slidably mounted on the sliding base via the slide rails. A brushing component is mounted on the sliding base, and a transmission component is mounted on the sliding base. The transmission component includes a first electric telescopic rod and a rotating rod connector. The first electric telescopic rod is mounted on the sliding base, and a transmission rotating rod is rotatably mounted on the output shaft of the first electric telescopic rod via the rotating rod connector. Transmission gears are symmetrically mounted on both sides of the transmission rotating rod, and the transmission gears mesh with a rack and pinion plate for transmission.

[0011] The sliding base slides at a constant speed from the end of the lead screw away from the output motor to the end closer to the output motor. When it slides to the position of the conveyor plate, the detection rollers are tightly fitted to both sides of the conveyor plate under the action of the second spring.

[0012] The scrubbing assembly includes a scrubbing connector, which is mounted on a sliding base. A first slider is slidably installed inside the scrubbing connector. A first spring is installed between the first slider and the scrubbing connector. A cleaning rod is rotatably installed between the first slider and the first slider. A brush wheel is installed on the cleaning rod, and a rotating gear is installed on one side of the brush wheel.

[0013] The brush wheel has water outlet holes that run through the inside and outside. The surface of the brush wheel is covered with bristles. A water supply device is connected to the outside of the brush wheel. The water supply device delivers high-pressure cleaning fluid into the brush wheel. The cleaning fluid is sprayed out from the water outlet holes, working in conjunction with the bristles to brush and spray the surface of the electric conveyor belt.

[0014] When oil stains are detected on the surface of the electric conveyor belt, the control system activates the first electric telescopic rod. The output shaft of the first electric telescopic rod drives the transmission rod to retract through the rotating rod connector. The transmission rod drives the transmission gears on both sides to retract. The transmission gears roll on the rack plate and move towards the rotating gear. When the transmission gears mesh with the rotating gear, the first electric telescopic rod retracts further. The transmission gears continue to move and lift the rotating gear. The rotating gear drives the cleaning rod to slide upward in the groove on the brush connector until the first spring is fully compressed. At this time, the cleaning rod drives the brush wheel to rise to its highest point, just enough to allow the brush wheel to rotate and thoroughly clean the surface of the electric conveyor belt. Then, the control system causes the drive motor to rotate in the opposite direction. The detection and maintenance component slides along the lead screw from the end closer to the output motor to the end farther away from the output motor. During the sliding, the transmission gear moves and rotates on the gear rack, which drives the rotating gear to rotate. The rotating gear drives the brush wheel to rotate, and the rotating brush wheel brushes the surface of the electric conveyor belt. The sliding base slides, causing the brush wheel to slide and brush at the same time. The horizontal scraper removes the dirt remaining on the surface of the electric conveyor belt, thereby achieving the cleaning and maintenance of the electric transmission belt surface.

[0015] The detector includes a detection base plate with wing plates on both sides. The wing plates have second sliding grooves, and the detection base plate has symmetrically arranged third sliding grooves and sliding holes. A friction detection component is slidably installed in the third sliding 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 stain detection plate is installed on the output shaft of the second electric telescopic rod. The oil stain detection plate is slidably connected to the second sliding groove, the oil stain detection plate is slidably connected to the wing plates, the friction detection component is slidably connected to the sliding groove, and the stain detection component is slidably connected to the oil stain detection plate.

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

[0017] The stain detection assembly 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 a sliding hole, and the other end of the detection slide rod is equipped with a measuring wheel connector. A detection roller is rotatably mounted on the measuring wheel connector. The first piezoelectric element is mounted on the detection base plate, and the detection slide rod passes through the first piezoelectric element. The first force transmission plate is slidably mounted on the detection slide rod, and a second spring is installed between the first force transmission plate and the measuring wheel connector. The measuring wheel connector is slidably connected to the oil stain detection plate.

[0018] When stains adhere to both sides of the conveyor plate, they cause bulges on the surface of the conveyor plate. When the detection roller rolls over the stain surface, it drives the detection slide rod to retract through the detection roller connector. When the detection roller connector retracts, it causes the second spring to compress. 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 and generates an 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 conveyor plate by the strength of the electric signal, and can analyze the position of the stain on the conveyor plate by the change time of the electric signal, thereby realizing the automatic detection of stains on the surface of the conveyor plate.

[0019] When stains are detected on the conveyor plate, the control system activates the second electric telescopic rod. The output shaft of the second electric telescopic rod drives the oil stain detection plate to slide, bringing the two oil stain detection plates closer together until they pass the conveyor plate. At this point, the vertical scraper can fit against the sides of the conveyor plate. As the sliding base moves the oil stain detection plate, the chamfer on the vertical scraper scrapes away the stains on both sides of the conveyor plate, thus achieving the inspection and maintenance of the conveyor plate. After cleaning, the inspection and maintenance device is activated again, and the above operation is repeated until the inspection is qualified. If the cleanliness of the electric drive belt and conveyor plate is consistently unqualified, and the inspection data no longer changes, it indicates that there is damage or other special conditions on the surface of the electric conveyor shell and conveyor plate. The control system then controls the unmanned garbage collection vessel to return for repair and inspection.

[0020] The oil stain detection plate is equipped with a sliding connector, a horizontal scraper, and a vertical scraper. Both the horizontal and vertical scrapers have chamfers, and the oil stain detection plate has rounded corners. The oil stain detection plate has a measuring wheel groove, and the oil stain detection plate is slidably connected to the measuring wheel connector through the measuring wheel groove. The oil stain detection plate is also connected to the output shaft of the second electric telescopic rod through the sliding connector.

[0021] The rounded corners allow the oil stain detection plate to quickly pass through when it encounters attached stains; the chamfers on the horizontal and vertical scrapers enable them to remove stains.

[0022] The sliding base slides and pushes the oil stain detection plate along the surface of the electric conveyor belt via the T-shaped slide rod. Friction is generated between the top surface of the oil stain detection plate and the surface of the electric conveyor belt. Under the action of friction, the oil stain detection plate slides relative to the sliding base. The oil stain detection plate drives the T-shaped slide rod to slide and retract along the slide rail via the second slider. The T-shaped rod 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 generates charge under pressure. 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 based on the change in the electrical signal, and judges whether there is still oil stain on the surface of the electric conveyor belt based on the change.

[0023] When the surface of the electric conveyor belt is clean, the friction between the top surface of the oil stain detection plate and the surface of the electric conveyor belt is relatively constant. When oil stains appear on the surface of the electric conveyor belt, the friction decreases, and the electrical signal becomes weaker. When stains adhere to the surface of the electric conveyor belt, the oil stain detection plate will drive the detection substrate to slide downward through the third slide groove as it passes through the stains, thus quickly passing through the stains. At the same time, the resistance brought by the stains to the oil stain detection plate will cause the T-shaped slide bar to retract rapidly for a short time, causing a sudden change in the electrical signal. The control system judges whether there are stains on the electric conveyor belt based on the sudden change in the electrical signal. When the detection roller is affected by the resistance of the stains and transmits the signal to the oil stain detection plate through the detection substrate, the control system combines the electrical signal of the second piezoelectric element. When the first and second piezoelectric elements change simultaneously, it proves that the detection roller caused the first piezoelectric element to generate a change in the electrical signal, thus ruling out the possibility that there are stains on the surface of the electric conveyor belt.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. Use a cleaning device to regularly clean the electric conveyor belt and conveyor plate to prevent garbage and oil stains from adhering for a long time, affecting the salvage efficiency, and causing corrosion and damage to the electric conveyor belt and conveyor plate.

[0026] 2. The oil stain detection plate converts the oil stains on the electric conveyor belt surface into frictional force, which is then converted into an electrical signal for identification. By identifying the strength of the electrical signal, the adhesion of the oil stains can be detected. Simultaneously, the adhesion of dirt on the electric conveyor belt surface is converted into abrupt electrical signals, which are then identified to detect dirt on the conveyor belt surface. Horizontal and vertical scrapers on the oil stain detection plate are used to scrape away dirt from the electric conveyor belt and conveyor plate surfaces.

[0027] 3. The stain detection component converts the adhesion of stains into the displacement of the detection roller, and then converts the displacement into a recognizable electrical signal. By analyzing the strength and change time of the electrical signal, the automatic detection of stains on the surface of the conveyor plate can be achieved.

[0028] 4. The transmission component drives the brush washing component to rise and fall automatically, and the rack and pinion plate drives the transmission component to rotate. No additional drive is required. The transmission component drives the brush wheel to rotate, thereby achieving cleaning and maintenance of the electric drive belt surface.

[0029] 5. The output motor drives the detection and maintenance components to move at a constant speed and stably via a lead screw, ensuring stability during the detection process. Attached Figure Description

[0052] The working principle of this invention is as follows: The control system controls the unmanned vessel 5 to travel to the water area where it needs to be salvaged. During travel, the unmanned vessel 5 will push the garbage forward, and with the help of the collection plates 2 on both sides, the garbage will be gathered in the middle. The control system will start 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 lift the garbage on the water surface from the bottom of the water, so that the garbage will follow the rotation of the electric conveyor belt 3. When the garbage that is lifted off the water surface moves to the position of the collection bin 1 with the electric conveyor belt 3, it will fall into the collection bin 1 as the electric conveyor belt 3 turns. Afterwards, the control system will intermittently start the cleaning device 7 according to the preset interval time to clean the electric conveyor belt 3 at regular intervals. According to the number of cleanings, the control system will intermittently start the detection and maintenance device 8.

[0053] 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, and the control system activates the electric lifting platform 6. The electric lifting platform 6 drives the detection and maintenance device 8 onto the platform until the oil stain detection plate 862 is in contact with the surface of the electric conveyor belt. Then, the output motor 81 is activated. The output shaft of the output motor 81 drives the lead screw 83 to rotate. The lead screw 83 drives the detection and maintenance component 84 to rotate. Since the sliding base 87 and the transmission base plate 82 are slidably connected through the first slide groove 871 and the slide rail 822, the detection and maintenance component 84 converts the rotation into linear sliding along the transmission base plate 82.

[0054] The sliding base 87 slides at a constant speed from the end of the lead screw 83 away from the output motor 81 to the end closer to the output motor 81. When it slides to the position of the conveyor plate 31, the detection roller 8653 is tightly attached to both sides of the conveyor plate 31 under the action of the second spring 8652.

[0055] When stains adhere to both sides of the conveyor plate 31, a bulge will form on the surface of the conveyor plate 31. When the detection roller 8653 rolls over the stain surface, it will drive the detection slide bar 8651 to retract through the detection roller connector 8654. When the detection roller connector 8654 retracts, it will drive the second spring 8652 to compress. 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 and generates an electric charge. The electric charge flows to the control system through the wire. The control system can analyze the size of the stain on the surface of the conveyor plate by the strength of the electric signal. According to the change time of the electric signal, the position of the stain on the conveyor plate 31 can be analyzed, thereby realizing the automatic detection of stains on the surface of the conveyor plate 31.

[0056] The sliding base 87 slides and pushes the oil stain detection plate 862 along the surface of the electric conveyor belt 3 via the T-shaped slide rod 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 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 rod 8641 to slide and retract along the slide rail 873 via the second slider 8646. The T-shaped rod retracts and compresses the third spring 8644. After being compressed, the third spring 8644 increases the elastic force on the second force transmission plate 8642. The second force transmission plate 8642 transmits the elastic force to the second piezoelectric element 8643. The second piezoelectric element 8643 generates charge under pressure. The 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 based on the change in the electrical signal, and judges whether there is still oil stain on the surface of the electric conveyor belt 3 based on the change.

[0057] 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 weakens. When stains adhere 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, thus 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, thus enabling the electrical signal to return to normal. When a sudden change occurs in the signal, the control system determines whether the electric conveyor belt 3 is covered with dirt based on the sudden change in the electrical signal. When the detection roller 8653 is affected by the resistance of the dirt and the signal is transmitted to the oil stain 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 simultaneously, it proves that the detection roller 8653 caused the first piezoelectric element 8656 to generate a change in electrical signal, thereby eliminating the possibility that there is dirt on the surface of the electric conveyor belt 3.

[0058] When oil stains are detected on the surface of the electric conveyor belt 3, the control system activates the first electric telescopic rod 884. The output shaft of the first electric telescopic rod 884 drives the transmission rod 882 to retract via the rotating rod connector 883. The transmission rod 882 drives the transmission gears 881 on both sides to retract. The transmission gears 881 roll on the rack plate 823 and move toward the rotating gear 853. When the transmission gear 881 meshes with the rotating gear 853, the first electric telescopic rod 884 retracts further. The transmission gear 881 continues to move and lifts the rotating gear 853. The rotating gear 853 drives the cleaning rod 856 to slide upward in the groove on the brushing connector 852 until the first spring 855 is fully compressed. At this time, the cleaning rod 856 drives the brush wheel 851 to rise to its highest point, so that the brush wheel 851 can fully brush the surface of the electric conveyor belt 3 when it rotates. Subsequently, the control system reverses the rotation of the drive motor, and the detection and maintenance component 84 slides along the lead screw 83 from the end near the output motor 81 to the end away from the output motor 81. During the sliding, the transmission gear 881 moves and rotates on the gear rack, which drives the rotating gear 853 to rotate. The rotating gear 853 drives the brush wheel 851 to rotate, and the rotating brush wheel 851 brushes the surface of the electric conveyor belt 3. The sliding base 87 slides, causing the brush wheel 851 to slide and brush at the same time. The horizontal scraper 8621 scrapes away the dirt remaining on the surface of the electric conveyor belt 3, thereby achieving the cleaning and maintenance of the electric transmission belt surface.

[0059] When stains are detected on the conveyor plate, the control system activates the second electric telescopic rod 861. The output shaft of the second electric telescopic rod drives the oil stain detection plate 862 to slide, bringing the two oil stain detection plates 862 closer together until they pass the conveyor plate 31. At this point, the vertical scraper 8625 can fit against both sides of the conveyor plate 31. When the sliding base 87 drives the oil stain detection plate 862 to slide, the chamfer on the vertical scraper scrapes away the stains on both sides of the conveyor plate 31, thus achieving the inspection and maintenance of the conveyor plate 31. After cleaning, the inspection and maintenance device 8 is activated again, and the above operation is repeated until the inspection is qualified. If the cleanliness of the electric drive belt and the conveyor plate 31 is consistently unqualified, and the inspection data no longer changes, it indicates that the electric conveyor belt and the surface of the conveyor plate 31 have been damaged or have other special conditions. The control system then controls the unmanned garbage collection vessel to return for repair and inspection.
