Description

Technical Field

[0001] The present application relates to the technical field of river garbage collection, and specifically to a river garbage interception and collection device and a method for using the same. Background Art

[0002] Urban artificial landscape tributaries or narrow artificial tributaries, with widths ranging from 5 to 15 meters, are prone to the problem of floating debris such as plastic packaging and fallen leaves being carried along by the current. Without effective interception facilities, this debris can quickly flow through the tributaries into the main river channel, continuously polluting public waters and natural bodies downstream. Due to the frequent rise and fall of water levels in these artificial waterways, which are affected by gate control and rainfall, traditional fixed waste collection devices are not adaptable. When the water level drops, the debris leaks from the bottom of the device, while when the water level rises, it overflows from the top, significantly reducing the interception efficiency.

[0003] The faster water flow in tributaries will accelerate the migration of garbage. Once unintercepted garbage enters open waters, it is more likely to decompose into microplastic pollutants that are difficult to clean up. At the same time, it significantly increases the complexity of cross-regional governance, and the lack of safe operation surfaces forces workers to rely on ships for cleaning. Summary of the Invention

[0004] In order to solve the above problems, the present application proposes a river garbage interception and collection device and a method of using the same.

[0005] A river garbage interception and collection device comprises a frame, with two sides of the frame being a water inlet surface and a water outlet surface respectively;

[0006] The intercepting component includes lifting units symmetrically arranged at both ends of the frame and an intercepting unit installed between the lifting units. The lifting unit includes an adjusting frame, a surface of the adjusting frame facing the water inlet surface is provided with a slide groove, and also includes at least one adjusting slider disposed in the slide groove and moving linearly along the slide groove surface. The adjusting frame is provided with a screw rod coaxial with the slide groove, and the adjusting slider is threadedly connected to the screw rod;

[0007] The interception unit includes a vertical fixing bar and a horizontal fixing bar arranged perpendicular to each other, and an interception net covering the area enclosed by the fixing bars. The vertical fixing bar and the horizontal fixing bar each include a first clamping member and a second clamping member. The edge of the interception net is clamped between the first clamping member and the second clamping member and fixed by a connecting member. The vertical fixing bar and the horizontal fixing bar are detachably connected to the adjustment slider.

[0008] Furthermore, a lifting motor for driving the screw rod to rotate is provided at the top of the frame.

[0009] Furthermore, the adjusting slider includes a slider body and a detachable mounting cover. The slider body is nested in the slide groove, and a threaded hole is provided in the center to engage with the screw rod. As the screw rod rotates, it rises and falls linearly along the slide groove. The mating surfaces of the two are provided with fixing grooves that are adapted to the shapes of the vertical fixing bars and the horizontal fixing bars. A fixing hole is provided on the surface of the fixing groove. The fixing hole on the mounting cover is a through hole. The connecting piece is passed through the fixing hole to integrate and fix the slider body, the detachable mounting cover, the fixing bar and the clamped intercepting net.

[0010] Furthermore, the matching surfaces of the slider body and the mounting cover are respectively provided with mutually engaged positioning structures, and the positioning structures include positioning blocks and positioning grooves with mutually adapted shapes.

[0011] Furthermore, the interception net comprises a base body with a planar mesh structure. Multiple filter holes are evenly distributed throughout the base body, with the inner edges of the holes covered with an anti-corrosion edging. Removable adsorption units are installed between adjacent rows of filter holes, with the surface of the adsorption units coplanar with the base body. The filter holes intercept floating debris larger than 15 mm, such as plastic bottles and fallen leaves. The adsorption units actively absorb oil, colloids, and microplastic fragments by loading activated carbon / ion exchange resin.

[0012] Furthermore, the anti-corrosion edging delays mesh rust, preventing microplastic leakage caused by corrosion-induced pore expansion; the adsorption unit can be replaced regularly to maintain continuous adsorption capacity.

[0013] Furthermore, the system also includes a collection unit, comprising a cleaning motor mounted on a frame. The motor's output end is connected to a rotating shaft and a shaft cylinder fixedly connected to the rotating shaft. A reel is symmetrically mounted on the shaft cylinder, and a rope is wound around the reel. The free end of the rope is connected to a garbage salvage box. Operators only need to press the motor button on the frame platform to open the box and clean the garbage, eliminating the risk of falling into the water during ship salvage operations.

[0014] Furthermore, the garbage salvage box includes an inclined sieve plate located at the bottom of the garbage salvage box with its lower end facing the water inlet surface, and also includes a plurality of movable flaps hinged to the side wall of the box body near the water inlet surface.

[0015] Furthermore, the movable flap can be turned outward and inward. When the movable flap turns inward, the garbage salvage box is partially immersed in water when salvaging garbage. When the water flow force is greater than the gravity of the flap, it automatically opens to form a water inlet, and the garbage flows into the box with the water flow. When the garbage salvage box is lifted, the screen plate is tilted to allow water to be quickly discharged from the lower end, reducing the lifting load. At the same time, the movable flap automatically closes due to gravity during the lifting process to prevent garbage from falling back into the water.

[0016] When the movable flap flips out of the box, an additional locking mechanism needs to be set to prevent the movable flap from opening due to its own gravity during the lifting process. When salvaging garbage, the garbage salvage box needs to be completely immersed in water so that the water flow drives the garbage into the garbage salvage box from above.

[0017] Furthermore, it also includes at least two stabilizing ropes, which are symmetrically fixedly connected to the top of the side wall of the box and connected to the rope.

[0018] Furthermore, a salvage box limiting slot is provided on the surface of the frame body close to the water inlet side, and the frame body also includes a salvage box limiting block that moves linearly along the salvage box limiting slot, and the salvage box limiting block is fixedly connected to the outer surface of the garbage salvage box.

[0019] Furthermore, a retractable telescopic column is vertically installed at the bottom of the frame, and the length can be adjusted manually or electrically. A pointed head is fixedly installed at the bottom of the telescopic column for extending into the riverbed fixing device, which is inserted into the riverbed to achieve rigid anchoring, ensuring that the frame remains stable under the impact of water flow; a solar panel is set on the top of the frame to power the motor, so as to adapt to the field without power supply environment.

[0020] Furthermore, a fence and a step are set on the top of the frame to facilitate salvage personnel to collect garbage from above. At this time, the motor needs an additional protective shell to shield it.

[0021] To assemble the interception net: Take the vertical and horizontal fixing bars, both of which include a first clamp and a second clamp. Place the edge of the interception net between the first and second clamps of the vertical and horizontal fixing bars, ensuring that the interception net flatly covers the area enclosed by the fixing bars. Use connecting members, such as bolts, to pass through the first clamp, the edge of the interception net, and the second clamp to secure.

[0022] Install the adsorption unit: embed the detachable adsorption unit between two adjacent rows of filter holes in the interception net matrix, ensuring that its surface is coplanar with the interception net matrix.

[0023] Connect the adjustment slider: Assemble the adjustment slider: insert the slider body into the slide groove of the adjustment frame, and the threaded hole in the center of the slider body engages with the screw rod;

[0024] Connect the fixing strips to the slider: insert the ends of the vertical fixing strips and the horizontal fixing strips into the fixing grooves on the matching surfaces of the slider body and the mounting cover; align the mounting cover with the slider body and position it by engaging the positioning block and the positioning groove; pass the connecting piece through the through-hole fixing hole of the mounting cover, the fixing strips and the fixing holes of the slider body, and lock them together to secure them.

[0025] A method for using a river garbage interception and collection device comprises the following steps:

[0026] Step 1: Anchor the frame: Adjust the length of the telescopic column so that the pointed end is inserted into the riverbed;

[0027] Adjust the direction of the frame to ensure that the water inlet surface faces the water flow.

[0028] Step 2: Adjust the height of the interception net: start the lifting motor to drive the screw to rotate; the screw drives the adjustment slider to rise and fall along the slide slot, and links the vertical fixing bar and the horizontal fixing bar to adjust the immersion depth of the interception net; make the top of the interception net 10-20cm above the water level line.

[0029] Step 3: Garbage collection: Start the cleaning motor to reverse, release the rope on the drum, and immerse the garbage salvage box vertically in water; the impact of the water flow pushes the movable flap to flip into the box, and the garbage flows into the box with the water flow; the sieve plate filters the water and the water flows out from the sieve holes.

[0030] Step 4: Garbage transfer: The cleaning motor rotates forward, and the drum reels in the rope to lift the garbage salvage box. During the lifting process, the movable flap automatically closes due to gravity to prevent the garbage from falling back; the residual water on the screen plate is quickly discharged from the lower end; the salvage box limit block slides along the salvage box limit slot to keep the box stable;

[0031] Dumping garbage: manually open the movable flap on the frame operating platform to dump the garbage; or clean it directly from above the garbage salvage box.

[0032] Compared with the prior art, this application has the following beneficial effects:

[0033] The liftable interception net has a screw mechanism that dynamically adjusts the immersion depth, ensuring that garbage does not leak from the bottom of the net during the dry season and does not overflow from the top of the net during the flood season, significantly improving the reliability of interception. At the same time, the interception net combines multi-stage filtration and adsorption functions to intercept large-sized floating objects, and actively capture oil and microplastic fragments through replaceable adsorption units. The anti-corrosion edging delays mesh rust and curbs the spread of micro-pollution at the source.

[0034] The garbage salvage box uses water flow to automatically open and close its flaps to collect trash. The tilted screen plate quickly drains water and reduces the load. Limiting chutes and stabilizing ropes ensure a stable lifting process. Operators complete garbage removal directly from the platform, completely avoiding the risks of ship operations. The modular design allows for single-piece replacement of the interception net, significantly reducing maintenance costs. The telescopic columns and riverbed anchoring structure provide rigid support against water impact, and solar power supply ensures long-term operation in the field. BRIEF DESCRIPTION OF THE DRAWINGS

[0069] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0070] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0071] Example 1

[0072] like Figure 1-5 As shown, a river garbage interception and collection device includes a frame 1, with a water inlet surface 101 and a water outlet surface 102 on both sides of the frame 1;

[0073] The intercepting component includes lifting units symmetrically arranged at both ends of the frame 1 and an intercepting unit installed between the lifting units. The lifting unit includes an adjusting frame 16. The adjusting frame 16 has a slide groove 1601 on its side surface facing the water inlet surface 101, and also includes at least one adjusting slider 18 arranged in the slide groove 1601 and moving linearly along the surface of the slide groove 1601. The adjusting frame 16 is provided with a screw rod 17 coaxial with the slide groove 1601, and the adjusting slider 18 is engaged with the screw rod 17 through an internal thread; when the lifting motor 19 drives the screw rod to rotate, the slider 18 rises and falls linearly along the slide groove 1601; the self-locking characteristics of the screw rod transmission can resist the impact force of the water flow and avoid the displacement of the interception net causing an interception gap.

[0074] The interception unit includes a vertical fixing bar 9 and a horizontal fixing bar 10 arranged perpendicular to each other, and an interception net 8 covering the area enclosed by the fixing bars. The vertical fixing bar 9 and the horizontal fixing bar 10 both include a first clamping member and a second clamping member. The edge of the interception net 8 is clamped between the first clamping member and the second clamping member and fixed by a connecting member. The vertical fixing bar 9 and the horizontal fixing bar 10 and the adjusting slider 18 are detachably connected; when the interception net 8 is blocked or damaged, the detachable fixing bar can realize the replacement of a single piece of net without the need to disassemble the lifting unit as a whole, which greatly reduces maintenance time; the fixing bar clamping design enables the interception net 8 to maintain flat tension during the lifting process, avoiding the net body from loosening and causing garbage to penetrate.

[0075] A lifting motor 19 is provided at the top of the frame 1 for driving the screw rod 17 to rotate.

[0076] By adjusting the immersion depth of the interception net 8 through the lifting motor 19, the interception net 8 is always kept 10-20 cm above the water level line, ensuring that garbage does not leak from the bottom of the net during the dry season and does not overflow from the top of the net during the flood season. It adapts to the frequent water level changes in the gate-controlled river channel and solves the interception failure problem caused by water level fluctuations in traditional fixed devices.

[0077] Example 2

[0078] like Figure 8-10 As shown, based on Example 1, a river garbage interception and collection device is provided, the adjusting slider 18 includes a slider body 1801 and a detachable mounting cover 1802, the slider body 1801 is nested in the slide groove 1601, and a threaded hole is provided in the center to engage with the screw rod 17, and it rises and falls linearly along the slide groove 1601 as the screw rod 17 rotates, and the mating surfaces of the two are provided with a fixing groove 1803 that is adapted to the shape of the vertical fixing bar 9 and the horizontal fixing bar 10, and a fixing hole 1804 is provided on the surface of the fixing groove 1803, and the fixing hole 1804 on the mounting cover 1802 is a through hole, and the connecting member is passed through the fixing hole 1804 to integrate and fix the slider body 1801, the detachable mounting cover 1802, the fixing bar and the clamped interception net 8.

[0079] The mating surfaces of the block body 1801 and the mounting cover 1802 are respectively provided with mutually engaged positioning structures, and the positioning structures include a positioning block 1805 and a positioning groove 1806 with mutually adapted shapes.

[0080] Example 3

[0081] like Figure 1-10 As shown, a river garbage interception and collection device includes a frame 1, with a water inlet surface 101 and a water outlet surface 102 on both sides of the frame 1;

[0082] The intercepting component includes lifting units symmetrically arranged at both ends of the frame 1 and an intercepting unit installed between the lifting units. The lifting unit includes an adjustment frame 16. The adjustment frame 16 has a chute 1601 on the side facing the water inlet surface 101, and also includes at least one adjustment slider 18 disposed in the chute 1601 and moving linearly along the surface of the chute 1601. The adjustment frame 16 is provided with a screw rod 17 coaxial with the chute 1601, and the adjustment slider 18 is threadedly connected to the screw rod 17;

[0083] The interception unit includes a vertical fixing bar 9 and a horizontal fixing bar 10 arranged perpendicular to each other, and an interception net 8 covering the area enclosed by the fixing bars. The vertical fixing bar 9 and the horizontal fixing bar 10 each include a first clamping member and a second clamping member. The edge of the interception net 8 is clamped between the first clamping member and the second clamping member and fixed by a connecting member. The vertical fixing bar 9 and the horizontal fixing bar 10 are detachably connected to the adjustment slider 18.

[0084] A lifting motor 19 is provided at the top of the frame 1 for driving the screw rod 17 to rotate.

[0085] The interception net 8 comprises a base body with a planar mesh structure. Multiple filter holes 801 are evenly distributed throughout the base body. The inner edges of these filter holes 801 are covered with an anti-corrosion edging 802. Adsorption units 803 are removably installed between adjacent rows of filter holes 801. The surfaces of these adsorption units 803 are coplanar with the base body. The filter holes 801 intercept floating debris larger than 15 mm, such as plastic bottles and fallen leaves. The adsorption units 803, loaded with activated carbon / ion exchange resin, actively absorb oil, colloids, and microplastic fragments measuring 1-15 mm.

[0086] The anti-corrosion edging 802 delays mesh corrosion, preventing microplastic leakage caused by corrosion-induced pore expansion; the adsorption unit 803 can be replaced regularly to maintain continuous adsorption capacity.

[0087] The system also includes a collection unit, comprising a cleaning motor 2 mounted on a frame 1. The output end of the cleaning motor 2 is connected to a rotating shaft 5 and a shaft cylinder 4 fixedly connected to the rotating shaft 5. A reel 6 is symmetrically mounted on the shaft cylinder 4. A rope 7 is wound around the reel 6, and the free end of the rope 7 is connected to a garbage salvage box 11. Operators only need to press the motor button on the frame platform to open the box and clean the garbage, avoiding the risk of falling into the water during ship salvage.

[0088] The garbage salvage box 11 includes an inclined sieve plate 1102 located at the bottom of the garbage salvage box 11 with its lower end facing the water inlet surface 101 , and also includes multiple movable flaps 1101 hinged to the box side wall on the side close to the water inlet surface 101 .

[0089] The movable flap 1101 can be turned outside the box and inside the box. When the movable flap 1101 is turned inside the box, the garbage salvage box 11 is partially immersed in water when salvaging garbage. When the impact of the water flow is greater than the gravity of the flap, it automatically opens to form a water inlet, and the garbage flows into the box with the water flow; when the garbage salvage box 11 is lifted, the screen plate 1102 is tilted to allow water to be quickly discharged from the lower end, reducing the lifting load. At the same time, during the lifting process, the movable flap 1101 automatically closes due to gravity to prevent garbage from falling back into the water.

[0090] When the movable flap 1101 flips out of the box, an additional locking mechanism 21 needs to be set to prevent the movable flap 1101 from opening due to its own gravity during the lifting process. When salvaging garbage, the garbage salvage box 11 needs to be completely immersed in water so that the water flow drives the garbage to flow into the garbage salvage box 11 from above.

[0091] It also includes at least two stabilizing ropes 1103 , which are symmetrically fixedly connected to the top of the side wall of the box and connected to the rope 7 .

[0092] The frame 1 is provided with a salvage box limiting slot 15 on the surface close to the water inlet surface 101 , and further includes a salvage box limiting block 12 that moves linearly along the salvage box limiting slot 15 , and the salvage box limiting block 12 is fixedly connected to the outer surface of the garbage salvage box 11 .

[0093] A retractable telescopic column 13 is vertically installed at the bottom end of the frame 1, and the length can be adjusted manually or electrically. A pointed head 14 for extending into a riverbed fixing device is fixedly installed at the bottom end of the telescopic column 13, and inserted into the riverbed to achieve rigid anchoring, ensuring that the frame remains stable under the impact of water flow; a solar panel 20 is provided on the top of the frame 1 to power the motor and adapt to the field without power supply environment.

[0094] A fence and a step are set at the top of the frame 1 to facilitate the salvage personnel to collect garbage from above. At this time, the motor needs an additional protective shell to shield it.

[0095] Example 4

[0096] A method for using a river garbage interception and collection device comprises the following steps:

[0097] Step 1: Anchoring the frame 1: Adjust the length of the telescopic column 13 so that the pointed end 14 is inserted into the riverbed;

[0098] Adjust the direction of the frame 1 to ensure that the water inlet surface 101 faces the water flow.

[0099] Step 2: Adjust the height of the interception net 8: Start the lifting motor 19 to drive the screw 17 to rotate; the screw 17 drives the adjustment slider 18 to rise and fall along the slide 1601, and links the vertical fixing bar 9 and the horizontal fixing bar 10 to adjust the immersion depth of the interception net 8; make the top of the interception net 8 10-20cm higher than the water level line.

[0100] Step 3: Garbage collection: Start the cleaning motor 2 to reverse, release the rope 7 on the drum 6, and immerse the garbage salvage box 11 vertically in the water; the impact of the water flow pushes the movable flap 1101 to flip into the box, and the garbage flows into the box with the water flow; the sieve plate 1102 filters the water, and the water flows out from the sieve holes.

[0101] Step 4: Garbage Transfer: The cleaning motor 2 rotates forward, and the drum 6 reels in the rope 7 to lift the garbage salvage box 11. During the lifting process, the movable flap 1101 automatically closes due to gravity to prevent the garbage from falling back. The residual water on the sieve plate 1102 is quickly discharged from the lower end. The salvage box limit block 12 slides along the salvage box limit chute 15 to keep the box stable.

[0102] Dumping garbage: manually open the movable flap 1101 on the operating platform of the frame 1 to dump garbage; or directly clean it from above the garbage salvage box 11.
