Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of river and lake garbage cleaning and collecting, in particular to an unmanned ship-mounted river and lake garbage cleaning and collecting device. BACKGROUND

[0002] China has numerous rivers and lakes, and the protection of the water ecological environment is of great importance. However, with the increase of human activities, a large amount of floating garbage (such as plastic bottles, plastic bags, foam, branches, waterweeds, etc.) is discarded or flows into rivers and lakes with rainwater, seriously polluting the water body, damaging the natural landscape, affecting the survival of aquatic organisms, and even blocking the river, reducing the flood control and drainage capacity.

[0003] At present, the cleaning work of river and lake surface floating garbage mainly relies on manual fishing by boat, large special cleaning ships or fixed pollution blocking and collecting devices. These existing technologies all have some problems. Manual fishing by boat, the operating personnel ride small boats and use simple tools such as nets and rakes to fish. This way has high labor intensity, low efficiency, limited operating range, and poses a threat to the personal safety of the operating personnel in bad weather or complex water environment.

[0004] Large cleaning ships with conveyors and storage bins are used in some areas. Although such ships have improved automation and efficiency, they are large in size, high in cost, not flexible in turning, cannot enter narrow, shallow or near-shore areas for operation, and have high operation and maintenance costs, making it difficult to be widely applied.

[0005] Pollution barriers or floating dams are set up in specific river channels to intercept garbage, which is then collected by manual or mechanical cleaning. This method is a passive collection method, and if the garbage is not cleaned in time after accumulation, it is easy to cause secondary diffusion and blockage, and it cannot actively clean the vast water area, so the applicability is limited.

[0006] The traditional manual fishing method requires the operating personnel to be exposed to the water surface for a long time, facing the risk of falling into the water, drowning, being cut by sharp garbage, etc., and the safety cannot be guaranteed. Large cleaning ships cannot enter shallow areas, narrow channels, wharf shores, aquatic plant areas and other complex water areas, leaving a large number of cleaning dead angles and blind areas, which greatly reduces the overall cleaning effect. Whether it is the labor cost required for manual fishing or the high purchase, fuel and maintenance costs of large cleaning ships, the economic burden of large-scale and normalized water surface cleaning work is heavy.

[0018] The present invention has the following beneficial effects: 1. The device's main body is moved by a propeller. During movement, surface debris enters the main housing through the debris inlet and is transported to the collection box by a conveyor belt. Both the lower interior of the main housing and the lower interior of the collection box feature mesh designs to allow water to drain out and prevent excessive water accumulation inside. The collection box and fixing components secure it in place. Rotating the adjustment knob rotates the connecting screw, which in turn moves the moving block.

[0019] 2. Through the setting of the lifting drive mechanism and the flow guiding drive mechanism, the drive motor drives the drive screw to rotate, and then the U-shaped connecting rod moves up and down through the fixed connection between the screw connecting plate and the U-shaped connecting rod. Since the two ends of the U-shaped connecting rod are connected to the telescopic mechanism respectively, the up and down movement of the U-shaped connecting rod will drive the telescopic mechanism to operate, and thus drive the flow guiding component to move. At the same time, due to the meshing connection between the transmission component and the transmission rack, when the first flow guiding plate drives the transmission component to move, the transmission component will drive the first transmission gear to drive the rotating shaft and the second flow guiding plate to rotate, and finally cause the second flow guiding plate to open. The setting of the first flow guiding plate and the second flow guiding plate can guide the garbage on the water surface for easy collection.

[0020] 3. The protective cover protects the flow-guiding drive mechanism, preventing damage from the external environment.

Through the coordinated operation of these components, this device not only efficiently collects and cleans river and lake waste but also possesses strong adaptability and flexibility, enabling stable operation in complex aquatic environments. Its high degree of automation reduces reliance on manpower and lowers operating costs. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1 Reference Figure 1 and Figures 3-9 As shown, this is the first embodiment of the present invention, which provides an unmanned vessel-borne river and lake garbage cleaning and collection device, including a device body 10, a lifting drive mechanism 20, a flow guiding drive mechanism 30, a protective cover 40, a mounting frame 50 and a thruster 60. The device body 10 includes a main shell 11 and a garbage inlet 12 opened at one end of the main shell 11. A conveyor belt mechanism 13 is provided on one side of the garbage inlet 12, and a collection box 14 is provided on the other side of the conveyor belt mechanism 13. A fixing component 15 is installed on the collection box 14. The mounting bracket 50 is fixedly mounted on the main housing 11 with bolts, and pushers 60 are fixedly mounted at both ends of the mounting bracket 50. The pushers 60 can be used to control the movement of the device. At the same time, the protective cover 40 is fixedly mounted on both sides of the main housing 11 with bolts, and the flow guide drive mechanism 30 is protected inside to prevent the flow guide drive mechanism 30 from being damaged by collision. Furthermore, the waste inlet 12 and the collection box 14 are respectively located on both sides of the main housing 11, and the conveyor belt mechanism 13 is located between the waste inlet 12 and the collection box 14, so that the waste entering the waste inlet 12 can be transported into the collection box 14; furthermore, the conveyor belt mechanism 13 is inclined and is driven by a drive motor to rotate. Furthermore, the bottom of the main housing 11 is perforated to facilitate water drainage.

[0026] The lifting drive mechanism 20 includes a mounting base 21 and a U-shaped connecting rod 22 disposed on one side of the mounting base 21. The cross-sectional shape of the U-shaped connecting rod 22 is "U". A lead screw connecting plate 23 is fixedly connected to the U-shaped connecting rod 22, and a drive lead screw 24 is disposed on the lead screw connecting plate 23. The mounting base 21 is fixedly mounted on the main housing 11. The U-shaped connecting rod 22 is set on one side of the mounting base 21, and both ends of the mounting base 21 are fixedly connected to the flow guiding drive mechanism 30. The screw connecting plate 23 is fixedly connected to the U-shaped connecting rod 22 by bolts. The screw connecting plate 23 is threadedly connected to the drive screw 24. The drive motor drives the drive screw 24 to rotate, which in turn allows the screw connecting plate 23 to move up and down and drives the U-shaped connecting rod 22 to move up and down. Furthermore, the lead screw connecting plate 23 is square and moves in the square groove in the mounting base 21, which can prevent the lead screw connecting plate 23 from rotating and enable it to move up and down stably.

[0027] The flow guiding drive mechanism 30 includes a fixed support 31 and a telescopic mechanism 32 connected to one side of the fixed support 31, and a sliding block 33 is connected to the other side of the telescopic mechanism 32. A flow guiding component 34 is fixedly connected to the sliding block 33. The fixed support 31 is fixedly connected to both sides of the main housing 11, and the main housing 11 and the fixed support 31 can also be integrally formed. One end of the telescopic mechanism 32 is rotatably connected to the fixed support 31 to limit its position, and the other end is rotatably connected to the U-shaped connecting rod 22. The other end of the telescopic mechanism 32 is provided with a mounting block and is installed with the sliding block 33, so that the mounting block can slide on the sliding block 33. When the U-shaped connecting rod 22 drives one end of the telescopic mechanism 32 to move, the telescopic mechanism 32 can be unfolded. The sliding of the mounting block on the telescopic mechanism 32 in the sliding block 33 can ensure that the telescopic mechanism 32 can push the flow guide component 34 to move when it is unfolded.

[0028] The flow guiding assembly 34 includes a first flow guiding plate 341 and a transmission assembly 342 installed inside the first flow guiding plate 341. A transmission rack 343 is provided on one side of the transmission assembly 342, a first transmission gear 344 is connected to one side of the transmission assembly 342, a rotating shaft 345 is connected to the first transmission gear 344, and a second flow guiding plate 346 is connected to the rotating shaft 345. The first guide plate 341 is fixedly connected to the sliding block 33, the transmission assembly 342 is installed inside the first guide plate 341, and the transmission rack 343 is disposed on the main housing 11, with a tooth block structure disposed inside the transmission rack 343; furthermore, the rotating shaft 345 is installed on one side inside the first guide plate 341, and the rotating shaft 345 is fixedly connected to the second guide plate 346, and the rotating shaft 345 and the second guide plate 346 can also be integrally formed; the second guide plate 346 can rotate on the first guide plate 341; The transmission assembly 342 includes a gear transmission belt 3421 and a second transmission gear 3422 connected to the gear transmission belt 3421. A third transmission gear 3423 is fixedly connected to one end of the second transmission gear 3422, and a fourth transmission gear 3424 is connected to one side of the third transmission gear 3423. The two ends of the gear transmission belt 3421 are respectively meshed with the second transmission gear 3422 and the first transmission gear 344, while the fourth transmission gear 3424 is meshed with the transmission rack 343.

[0029] When the drive motor starts, the rotation of the drive screw 24 is transmitted to the screw connecting plate 23 through the threaded connection, causing the screw connecting plate 23 to move up and down in the square groove of the mounting base 21. Since the U-shaped connecting rod 22 is fixedly connected to the screw connecting plate 23, the U-shaped connecting rod 22 will also move up and down. This movement is transmitted to the sliding block 33 through the connection structure of the telescopic mechanism 32, causing one end of the telescopic mechanism 32 to be pulled or pushed, while the other end rotates around the rotation point on the fixed support 31, thereby realizing the unfolding or retracting action of the telescopic mechanism 32.

[0030] As the telescopic mechanism 32 unfolds, the mounting block on it slides within the sliding block 33, further propelling the entire flow guide assembly 34 outward. During the movement of the transmission assembly 342 inside the first flow guide plate 341, the meshing transmission between the gear transmission belt 3421, the second transmission gear 3422, and the first transmission gear 344 ensures effective power transmission. The meshing connection between the fourth transmission gear 3424 and the transmission rack 343 enables the first transmission gear 344 to drive the rotating shaft 345 and the second flow guide plate 346 to rotate, ultimately achieving the opening action of the second flow guide plate 346.

[0031] The open state of the second guide plate 346 creates a guiding effect on the water surface, directing floating garbage to the working area of ​​the device for subsequent collection operations. Simultaneously, the inclined design of the conveyor belt mechanism 13 and the drive motor enable it to efficiently transport garbage entering from the garbage inlet 12 to the collection box 14. During this process, the mesh design at the bottom of the main housing 11 and the collection box 14 ensures that accumulated water can be drained in a timely manner, preventing the device from being affected by excessive water accumulation, thus avoiding reduced operating efficiency or increased load.

[0032] Example 2 Reference Figures 1-4 As shown, this is the second embodiment of the present invention. Based on the first embodiment, the further improvement is that the collection box 14 includes a box body 141 and a drainage mesh hole 142 disposed at the bottom of the box body 141. A mounting plate 143 is fixedly connected to the box body 141. The mounting plate 143 is fixedly connected to the box 141 and has mounting holes therein. It cooperates with the fixing component 15 to complete the installation and disassembly of the collection box 14.

[0033] The fixing component 15 includes a fixing base 151 and an adjusting knob 152 installed at one end of the fixing base 151. A connecting screw 153 is fixedly connected to one end of the adjusting knob 152. A movable block 154 is connected to the connecting screw 153, and a claw 155 is connected to the outside of the movable block 154. The fixed base 151 is fixedly connected to the main housing 11 and is connected to the mounting hole on the mounting plate 143. The adjusting knob 152 is provided with a limit block. The adjusting knob 152 is installed on the fixed base 151 so that the adjusting knob 152 can rotate on the fixed base 151 without falling off. Furthermore, the connecting screw 153 is fixedly connected to one side of the adjusting knob 152 and is located inside the fixed base 151. The connecting screw 153 is threadedly connected to the moving block 154, so that the moving block 154 can move. The moving block 154 and the pawl 155 are engaged to move the pawl 155.

[0034] The movable block 154 includes a movable block body 1541 and a first wedge 1542 fixedly connected to the outside of the movable block body 1541. A limit guide rod 1543 is connected inside the movable block body 1541. The movable block 1541 is fixedly connected to the first wedge 1542, and the first wedge 1542 is symmetrically arranged on the movable block 1541. The limiting guide rod 1543 is fixedly connected to the inside of the fixed base 151, so that the movable block 1541 moves on the limiting guide rod 1543 to limit the movement and ensure that the first wedge 1542 will not rotate. The claw component 155 includes a claw body 1551 and an extension 1552 fixedly connected to one side of the claw body 1551, and a second wedge 1553 is fixedly connected to the other side of the claw body 1551. A third wedge 1554 is provided on one side of the second wedge 1553. The protrusion 1552 can extend or retract on the fixed base 151, and the second wedge 1553 and the third wedge 1554 are both fixedly connected to the claw body 1551. Furthermore, the first wedge 1542, the second wedge 1553, and the third wedge 1554 are all inclined at the same angle, and the first wedge 1542 is connected to the second wedge 1553 and the third wedge 1554.

[0035] Example 3 Reference Figures 1-9 As shown, this is the third embodiment of the present invention. Based on embodiments 1 and 2, its working principle and process are as follows: In actual operation, the device achieves autonomous movement through the coordinated action of the mounting frame 50 and the propeller 60, ensuring its flexible operation in river and lake waters. When the device enters the working area, the drive motor starts, driving the drive screw 24 to rotate, and then the U-shaped connecting rod 22 moves up and down through the fixed connection between the screw connecting plate 23 and the U-shaped connecting rod 22. Since the two ends of the U-shaped connecting rod 22 are respectively connected to the telescopic mechanism 32, this movement is transmitted to the telescopic mechanism 32, causing it to rotate around the rotation point on the fixed support 31, thereby realizing the unfolding or retracting action. As the telescopic mechanism 32 unfolds, the mounting block set on it slides in the sliding block 33, further pushing the flow guiding assembly 34 to move outward as a whole.

[0036] Meanwhile, during the movement of the transmission assembly 342 inside the first guide plate 341, the meshing transmission between the gear transmission belt 3421, the second transmission gear 3422, and the first transmission gear 344 ensures effective power transmission. The meshing connection between the fourth transmission gear 3424 and the transmission rack 343 enables power transmission, allowing the first transmission gear 344 to drive the rotating shaft 345 and the second guide plate 346 to rotate, ultimately achieving the opening action of the second guide plate 346. The opened state of the second guide plate 346 can create a guiding effect on the water surface, guiding floating garbage to the working area of ​​the device for subsequent collection operations.

[0037] During the waste collection phase, the inclined design of the conveyor belt mechanism 13 and the drive of the motor enable it to efficiently transport waste entering from the waste inlet 12 to the collection bin 14. The internal structural design of the collection bin 14 ensures that waste can be effectively stored, while the mesh design at the bottom ensures that accumulated water can be drained in a timely manner, preventing the device from increasing its load or affecting its operating efficiency due to excessive water accumulation.

[0038] By setting up the collection box 14 and the fixing component 15, rotating the adjustment knob 152 can drive the connecting screw 153 to rotate, thereby moving the movable block 154 that is threadedly connected to the connecting screw 153. Then, by utilizing the cooperation between the movable block 154 and the claw 155, the claw 155 can move to extend or retract on the fixing seat 151, thus completing the installation and fixing of the collection box 14. This makes it convenient to install and remove the collection box 14, and facilitates the cleaning of the garbage collected in the collection box 14.

[0039] Throughout the entire operation, the protective cover 40 provides significant protection, effectively preventing damage to the flow guide drive mechanism 30 from the external environment. At the same time, it is fixed to the main body 10 of the device with bolts to ensure the stability of the overall structure.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
