Description

Technical Field

[0001] This application relates to the field of river treatment technology, and in particular to a self-collecting device for floating garbage in rivers. Background Technology

[0002] River surfaces are often littered with various plastic products, paper, fallen leaves, and other floating debris. This debris not only affects the aesthetics of the river but also poses serious threats to water quality, the ecological environment, and the lives of nearby residents. For example, the presence of floating debris can clog river channels, affecting the normal flow of water and increasing the risk of natural disasters such as floods. The decomposition of the debris consumes oxygen in the water, releases harmful substances, deteriorates water quality, and impacts the survival and reproduction of aquatic life. Therefore, the management of floating debris on river surfaces has always been a key focus of municipal engineering projects.

[0003] However, traditional river garbage cleanup work mostly involves salvage workers manually retrieval floating garbage from boats using tools, then piling it on the boats before transporting it ashore for sorting and processing. This conventional river garbage cleanup work is time-consuming and labor-intensive, requiring workers to spend a lot of time navigating the river to clean it, and it cannot continuously clean the river. The efficiency of river garbage cleanup is low and has obvious shortcomings. Utility Model Content

[0004] To improve the cleaning effect of river garbage, this application provides a self-collecting device for floating garbage in rivers.

[0005] The self-collection device for floating garbage in river channels provided in this application adopts the following technical solution:

[0006] A self-collecting device for floating garbage in a river includes a concrete foundation on the riverbed, a box body on the concrete foundation, a drive shaft rotatably connected inside the box body, an outer cylinder at the end of the drive shaft, and an inner cylinder inside the outer cylinder. The axes of the drive shaft, the outer cylinder, and the inner cylinder are all aligned on a straight line. Multiple blades are arranged on the inner sidewall of the inner cylinder, and the multiple blades are evenly distributed circumferentially. A filter plate for intercepting garbage is provided at the bottom of the inner cylinder, and the filter plate has multiple filter holes. Drainage outlets are provided on the sidewalls of both the inner and outer cylinders, and the drainage outlets are located below the filter plate. A drive assembly for driving the drive shaft to rotate is provided inside the box body.

[0007] By adopting the above technical solution, the drive component drives the transmission shaft to rotate, which in turn drives the outer and inner cylinders to rotate. The rotation of the inner cylinder causes multiple blades to rotate around the axis of the inner cylinder. When the blades rotate, a water vortex is generated on the water surface. At this time, the floating garbage on the river surface enters the inner cylinder with the water flow due to the centripetal force at the water vortex. Furthermore, under the interception of the filter plate, the floating garbage cannot be discharged back into the river through the drain outlet. This setup achieves continuous and effective collection of river surface garbage through the water vortex. Moreover, by installing multiple self-collecting devices in the river, comprehensive collection of floating garbage in the river is achieved, saving time and labor and effectively improving the cleaning efficiency of river garbage.

[0008] Optionally, the drive assembly includes a drive motor disposed inside the housing, the output shaft of the drive motor is provided with a drive gear, a reduction gear set is meshed on the drive gear, a transmission gear is meshed on the reduction gear set, and the transmission gear is coaxially and fixedly connected to the transmission shaft.

[0009] By adopting the above technical solution, the drive motor drives the drive gear to rotate. Under the transmission of the reduction gear set, the drive gear drives the transmission gear to rotate. The rotation of the transmission gear drives the outer cylinder to rotate. The drive motor provides stable and continuous power for the rotation of the transmission shaft, thereby ensuring the stable rotation of the inner cylinder around the clock. This effectively ensures the stable generation of water vortex, ensures the continuous operation of garbage collection, and further improves the efficiency of river garbage cleaning.

[0010] Optionally, the outer surfaces of the inner cylinders are provided with protrusions, and the inner walls of the outer cylinders are provided with grooves that slide with the protrusions. The length direction of the grooves is parallel to the axial direction of the outer cylinders.

[0011] By adopting the above technical solution, the grooves and ridges prevent relative rotation between the inner and outer cylinders, improving the stability of the inner cylinder's rotation. Simultaneously, the grooves and ridges enable a detachable connection between the outer and inner cylinders. After the garbage inside the inner cylinder is collected, workers pull the inner cylinder outwards to detach it from the outer cylinder, then remove the garbage from the inner cylinder. After removal, workers push the inner cylinder back into the outer cylinder via the sliding connection between the ridges and grooves for subsequent collection. This design ensures timely cleaning of the garbage inside the inner cylinder, reducing the possibility of excessive garbage overflowing back onto the river surface and guaranteeing effective cleaning of the river surface.

[0012] Optionally, the outer cylinder is provided with an anti-floating component, which includes a pull rod slidably connected to the side wall of the outer cylinder, a locking block on the pull rod, a receiving groove on the outer cylinder that slidably engages with the locking block, a locking groove on the outer side wall of the inner cylinder that engages with the locking block, a retaining spring inside the receiving groove, one end of the retaining spring being disposed on the inner side wall of the receiving groove, and the other end being disposed on the locking block, wherein in the natural state of the retaining spring, the locking block is engaged in the locking groove.

[0013] By adopting the above technical solution, during the rotation of the inner cylinder, the clamping spring pushes the locking block to press against the slot. The locking cooperation between the slot and the locking block achieves the vertical limitation of the inner cylinder, effectively preventing the inner cylinder from floating upward due to external forces during rotation, improving the stability of the inner cylinder during rotation, and ensuring the continuous operation of the garbage collection device.

[0014] Optionally, the inner bottom wall of the inner cylinder is provided with cleaning pins corresponding to the plurality of filter holes one by one. The inner sidewalls opposite to each other of the inner cylinder are provided with sliding grooves and guide grooves. A nut block is slidably connected in the sliding groove and a guide block is slidably connected in the guide groove. The two ends of the filter plate are respectively set on the nut block and the guide block. The inner cylinder is provided with an installation cavity communicating with the sliding groove. A double-headed motor is provided in the installation cavity. One of the output shafts of the double-headed motor is provided with a reciprocating screw. The nut block is threadedly connected to the reciprocating screw. When the guide block moves to the end of the guide groove near the inner bottom wall of the inner cylinder, the cleaning pin is inserted into the filter hole.

[0015] By adopting the above technical solution, during the inner cylinder cleaning process, a dual-head motor drives a reciprocating screw to rotate. The rotation of the reciprocating screw causes the filter plate to move towards the bottom wall of the inner cylinder. During the movement of the filter plate, cleaning nails are gradually inserted into the filter holes and push out the debris blocking the filter holes. After the cleaning nails have finished cleaning, the reciprocating screw drives the filter plate to move towards the opening of the inner cylinder. This setting realizes intermittent cleaning of the filter holes, ensuring the unobstructed state of the filter holes and thus ensuring the smooth discharge of water inside the inner cylinder. This avoids water accumulation in the inner cylinder and prevents garbage from overflowing into the river, thereby improving the cleaning effect of river garbage.

[0016] Optionally, a crushing shaft is rotatably connected inside the inner cylinder, the length direction of the crushing shaft is perpendicular to the axis of the inner cylinder, a plurality of crushing blades are provided on the crushing shaft, and a rotating assembly for driving the crushing shaft to rotate is provided inside the mounting cavity.

[0017] By adopting the above technical solution, the rotating component drives the crushing shaft to rotate, and the rotation of the crushing shaft drives multiple crushing blades to rotate synchronously. During the rotation of the crushing blades, large-volume waste is effectively cut and crushed, turning large-volume waste into small-volume waste. This effectively avoids the possibility of large-volume waste entering the inner cylinder and clogging the filter holes, while reducing the space occupied by waste and increasing the collection capacity inside the inner cylinder.

[0018] Optionally, the rotating assembly includes a worm gear fixedly connected coaxially to the crushing shaft. The worm gear is rotatably disposed within the mounting cavity. A worm is fixedly connected coaxially to the output shaft of the dual-head motor away from the reciprocating screw. The worm meshes with the worm gear.

[0019] By adopting the above technical solution, the dual-head motor drives the reciprocating screw to rotate while simultaneously driving the worm gear to rotate. The worm gear drives the worm wheel to rotate, and the worm wheel rotation drives the crushing shaft to rotate. At this time, the crushing blades rotate around the crushing shaft, thereby realizing the cutting of large-volume waste. This setting enables a single drive source to drive the filter plate cleaning function and the crushing function simultaneously, avoiding the space occupation caused by setting a separate motor for each function and improving the space utilization of the installation cavity.

[0020] Optionally, a waste volume sensor is provided on the inner wall of the inner cylinder, and a buzzer is provided on the outer cylinder. The waste volume sensor is electrically connected to the buzzer through a control system.

[0021] By adopting the above technical solution, when the garbage volume sensor detects that the garbage inside the inner cylinder has been collected, the garbage volume sensor controls the buzzer to start so that the cleaning personnel can receive the information and effectively clean the inner cylinder. This setting realizes timely reminder to the cleaning personnel and avoids the possibility of garbage overflowing into the inner cylinder and returning to the river channel, causing secondary pollution, due to failure to detect it in time.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application sets up a drive assembly, an inner cylinder, and blades. The drive assembly drives the inner cylinder to rotate, and the rotation of the inner cylinder causes multiple blades to rotate around the axis of the inner cylinder. When the blades rotate, they generate a water vortex on the water surface. At this time, the floating garbage on the river surface enters the inner cylinder with the water flow due to the centripetal force at the water vortex. In this way, the continuous and effective collection of river garbage is achieved through the water vortex. Furthermore, by installing multiple self-collecting devices in the river, the comprehensive collection of floating garbage in the river is achieved, saving time and effort and effectively improving the cleaning efficiency of river garbage.

[0024] 2. This application sets up an anti-floating component. During the rotation of the inner cylinder, the clamping spring pushes the locking block to press against the locking groove. The locking groove and the locking block are engaged to limit the vertical position of the inner cylinder, effectively preventing the inner cylinder from floating upward due to external forces during rotation. This improves the stability of the inner cylinder during rotation and ensures the continuous operation of the garbage collection device.

[0025] This application incorporates a reciprocating screw, a double-headed motor, and cleaning pins. The reciprocating screw drives the filter plate to move back and forth. During the movement of the filter plate, the cleaning pins gradually insert into the filter holes and push out the debris blocking them. This design enables intermittent cleaning of the filter holes, ensuring their unobstructed flow and thus guaranteeing the smooth discharge of water from the inner cylinder. This prevents water accumulation in the inner cylinder from causing garbage to overflow into the river, thereby improving the cleaning effect on river garbage. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a self-collecting device for floating garbage in river channels.

[0032] Reference Figure 1 and Figure 2A self-collecting device for floating garbage in a river includes a concrete foundation 1, which is fixedly installed on the riverbed. A box 2 is fixedly installed on the concrete foundation 1. In this embodiment, the box 2 is made of stainless steel. A drive shaft 21 is rotatably connected inside the box 2. The end of the drive shaft 21 extends upward along the vertical direction of the river. An outer cylinder 3 is fixedly connected to the end of the drive shaft 21. The top surface of the outer cylinder 3 is located below the horizontal plane of the river. Grooves 31 are provided on the opposite inner sidewalls of the outer cylinder 3. A protrusion 311 is slidably connected inside each groove 31. An inner cylinder 4 is fixedly connected between two protrusions 311. The inner cylinder 4 is slidably connected inside the outer cylinder 3 and its outer surface is in close contact with the inner surface of the outer cylinder 3. The axes of the outer cylinder 3, the inner cylinder 4 and the drive shaft 21 are all on the same straight line. A drive assembly 5 for driving the drive shaft 21 to rotate is provided inside the box 2.

[0033] Reference Figure 1 and Figure 2 The drive assembly 5 includes a drive motor 51 fixedly installed inside the housing 2. The output shaft of the drive motor 51 is fixedly connected to a drive gear 52. A reduction gear set 53 is meshed on the drive gear 52. A transmission gear 54 is meshed on the reduction gear set 53. The drive gear 52, the transmission gear 54 and the reduction gear set 53 are all rotatably connected inside the housing 2. The transmission gear 54 is coaxially fixedly connected to the end of the transmission shaft 21 located inside the housing 2.

[0034] Reference Figure 1 and Figure 2 Multiple blades 41 are fixedly connected to the inner wall of the inner cylinder 4. The blades 41 are streamlined. In this embodiment, there are six blades 41. The six blades 41 are evenly distributed in a circumferential shape on the inner circumference of the inner cylinder 4. Multiple interconnected drain ports 42 are opened on the inner walls of both the inner cylinder 4 and the outer cylinder 3. The multiple drain ports 42 are evenly distributed in a circumferential shape. A filter plate 43 is provided at the bottom of the inner cylinder 4. The outer surface of the filter plate 43 is tightly attached to the inner wall of the inner cylinder 4. Multiple filter holes 431 are opened on the filter plate 43. The height of the bottom surface of the filter plate 43 is higher than the height of the top surface of the drain port 42. A garbage volume sensor (not shown in the figure) is fixedly connected to the inner wall of the inner cylinder 4. A buzzer is fixedly installed on the outer surface of the outer cylinder 3. The garbage volume sensor is electrically connected to the buzzer through the control system.

[0035] Multiple garbage collection devices are installed in the river channel according to its area, covering the entire channel. After installation, the drive motor 51 is started, driving the drive gear 52 to rotate. Under the transmission of the reduction gear set 53, the drive gear 52 drives the transmission gear 54 to rotate. The rotation of the transmission gear 54 drives the outer cylinder 3 to rotate. With the connection of the groove 31 and the convex strip 311, the rotation of the outer cylinder 3 drives the inner cylinder 4 to rotate. The rotation of the inner cylinder 4 causes multiple blades 41 to rotate around the axis of the inner cylinder 4. When the blades 41 rotate, they create a water vortex on the water surface. At this time, the river... Floating debris on the surface enters the inner cylinder 4 with the water flow due to the centripetal force at the water vortex. Under the interception of the filter plate 43, the floating debris cannot be discharged back into the river through the drain outlet 42. The water in the debris passes through the filter hole 431 and the drain outlet 42 and is discharged back into the river. This setting realizes the continuous and effective collection of river surface debris through the water vortex. The drive component 5 provides stable and continuous power for the rotation of the drive shaft 21, ensuring the stable rotation of the inner cylinder 4 around the clock, thereby effectively ensuring the stable generation of the water vortex, saving time and effort, and effectively improving the cleaning efficiency of river debris.

[0036] When the waste volume sensor detects that the waste inside the inner cylinder 4 has been collected, the sensor controls the buzzer to start. After receiving the information, the cleaning personnel use the sliding cooperation of the groove 31 and the convex strip 311 to pull the inner cylinder 4 out of the outer cylinder 3. Then, the waste in the inner cylinder 4 is transferred to a designated location. After cleaning, the inner cylinder 4 is put back into the outer cylinder 3. This setting realizes timely reminders to the cleaning personnel and avoids the possibility of waste overflowing from the inner cylinder 4 and returning to the river, causing secondary pollution, due to failure to detect it in time.

[0037] Reference Figure 2 and Figure 3 To improve the stability of the inner cylinder 4 during rotation, an anti-floating component 6 is provided on the outer cylinder 3. The anti-floating component 6 includes a pull rod 61. A through hole (not shown in the figure) is provided on the side wall of the outer cylinder 3 for the pull rod 61 to pass through. A locking block 62 is fixedly connected to the end of the pull rod 61 near the inner cylinder 4. A receiving groove 32 is provided on the outer cylinder 3 to slide with the locking block 62. The receiving groove 32 is connected to the through hole. A locking groove 44 is provided on the outer side wall of the inner cylinder 4 to engage with the locking block 62. A retaining spring 63 is provided in the receiving groove 32. One end of the retaining spring 63 is fixedly connected to the inner side wall of the receiving groove 32, and the other end is fixedly connected to the locking block 62. In the natural state, the locking block 62 is engaged in the locking groove 44.

[0038] When installing the inner cylinder 4, the worker pulls the pull rod 61 outward, and the retaining spring 63 is compressed under tension. After the pull rod 61 drives the locking block 62 to be embedded in the receiving groove 32, the worker uses the guiding action of the protrusion 311 and the groove 31 to install the inner cylinder 4 into the outer cylinder 3. Then, the force on the pull rod 61 is released, and the retaining spring 63 resets, pushing the end of the locking block 62 to engage in the locking groove 44. With the engaging cooperation between the locking groove 44 and the locking block 62, the inner cylinder 4 is limited in the vertical direction during rotation, effectively preventing the inner cylinder 4 from floating upward due to external forces during rotation, improving the stability of the inner cylinder 4 during rotation, and ensuring the continuous operation of the garbage collection device.

[0039] Reference Figure 2 and Figure 3 Cleaning pins 7, corresponding one-to-one with multiple filter holes 431, are fixedly connected to the inner bottom wall of the inner cylinder 4. The cleaning pins 7 are vertically arranged. Sliding grooves 45 and guide grooves 46 are opened on the opposite inner side walls of the inner cylinder 4. Both sliding grooves 45 and guide grooves 46 are located near the bottom of the inner cylinder 4. A nut block is slidably connected in the sliding groove 45, and a guide block 461 is slidably connected in the guide groove 46. The two ends of the filter plate 43 are fixedly connected to the nut block and the guide block 461, respectively. An installation cavity 8 communicating with the sliding groove 45 is opened in the side wall of the inner cylinder 4. A double-head motor 81 is installed in the installation cavity 8. One of the output shafts of the double-head motor 81 is coaxially fixedly connected to a reciprocating screw 82. The nut block is threadedly connected to the reciprocating screw 82. When the guide block 461 moves to the end of the guide groove 46 near the inner bottom wall of the inner cylinder 4, the cleaning pins 7 are inserted into the filter holes 431, and the height of the bottom surface of the filter plate 43 is higher than the drain outlet 42.

[0040] During the cleaning process of the inner cylinder 4, the dual-head motor 81 drives the reciprocating screw 82 to rotate. The rotation of the reciprocating screw 82 drives the filter plate 43 to move back and forth along the length of the reciprocating screw 82. As the filter plate 43 moves toward the bottom wall of the inner cylinder 4, the cleaning nail 7 gradually inserts into the filter hole 431 and pushes out the debris blocking the filter hole 431. After the cleaning nail 7 has finished cleaning, the reciprocating screw 82 drives the filter plate 43 to move toward the opening of the inner cylinder 4. This setting realizes the intermittent cleaning of the filter hole 431, ensuring the unobstructed state of the filter hole 431 and thus ensuring the smooth discharge of water inside the inner cylinder 4. This avoids the accumulation of water in the inner cylinder 4, which could cause garbage to overflow into the river, and improves the cleaning effect of river garbage.

[0041] Reference Figure 2 and Figure 3Inside the inner cylinder 4, a crushing shaft 9 is rotatably connected. The length direction of the crushing shaft 9 is perpendicular to the axis of the inner cylinder 4. Multiple crushing blades 91 are fixedly connected to the crushing shaft 9. A rotating assembly 10 for driving the crushing shaft 9 is provided inside the mounting cavity 8. Specifically, the rotating assembly 10 includes a worm gear 101 that is coaxially fixedly connected to the crushing shaft 9. The worm gear 101 is rotatably connected inside the mounting cavity 8. A worm 102 is coaxially fixedly connected to the output shaft of the double-head motor 81 away from the reciprocating screw 82. The worm 102 is meshed with the worm gear 101.

[0042] The dual-head motor 81 drives the reciprocating screw 82 to rotate while simultaneously driving the worm gear 102 to rotate. The worm gear 102 drives the worm wheel 101 to rotate, and the rotation of the worm wheel 101 drives the crushing shaft 9 to rotate. At this time, the crushing blade 91 rotates around the crushing shaft 9. During the rotation, the large volume floating garbage that enters the inner cylinder 4 is cut and crushed, turning the large volume garbage into small volume garbage. This effectively avoids the possibility of large volume garbage entering the inner cylinder 4 and clogging the filter hole 431. At the same time, it reduces the space occupied by garbage and increases the collection capacity inside the inner cylinder 4.

[0043] The implementation principle of a self-collecting device for floating garbage in a river according to an embodiment of this application is as follows: Multiple garbage collection devices are installed in the river according to its area, so that the collection range of the garbage collection devices covers the entire river. After installation, the drive motor 51 is started, which drives the drive gear 52 to rotate. Under the transmission of the reduction gear set 53, the drive gear 52 drives the transmission gear 54 to rotate. The rotation of the transmission gear 54 drives the outer cylinder 3 to rotate. With the connection of the groove 31 and the convex strip 311, the rotation of the outer cylinder 3 drives the inner cylinder 4 to rotate. The rotation of the inner cylinder 4 causes multiple blades 41 to rotate around the axis of the inner cylinder 4. When the blades 41 rotate... The system creates a water vortex on the water surface. Floating debris on the river surface enters the inner cylinder 4 due to the centripetal force of the vortex. Because of the interception by the filter plate 43, the floating debris cannot be discharged back into the river through the drain outlet 42. The water in the debris passes through the filter holes 431 and the drain outlet 42 and is discharged back into the river. This design achieves continuous and effective collection of river debris through the water vortex. Furthermore, the drive assembly 5 provides stable and continuous power for the rotation of the drive shaft 21, ensuring the stable rotation of the inner cylinder 4 around the clock. This effectively guarantees the stable generation of the water vortex, saving time and effort and significantly improving the efficiency of river debris cleanup.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
