[0001] This invention belongs to the field of river management technology, specifically relating to a green ecological management and purification device for river water environment and its usage method. Background Technology

[0002] Rivers and waterways are a city's precious natural resource, playing a vital role in maintaining the balance and health of the urban ecosystem and in many aspects of urban economic and social life. However, with rapid economic and social development, the dramatic increase in urban population, and the rise of urban industrial economy, the ecological functions of urban waterways are constantly degrading and being lost, waterway pollution is becoming increasingly serious, and the pressure to manage them is relatively increasing.

[0003] A surface garbage collector is a device specifically designed to collect floating garbage and pollutants from the surface of water bodies. It is commonly used in rivers, lakes, ports, and oceans to reduce water pollution and protect the habitat of aquatic life. Currently, floating collectors typically employ a floating design, using buoyancy to float on the water surface and utilizing the up-and-down movement of an inner cylinder to drive water flow and collect floating garbage. For example, patent application CN114606917B discloses a surface garbage collector including a control chamber. An outer barrel is positioned above the control chamber, and a plastic float ring is detachably connected to the top of the outer barrel via screws.

[0017] This invention also discloses a method for using a green ecological treatment and purification device for river water environment, including the aforementioned green ecological treatment and purification device for river water environment. When cleaning up garbage, the outer cylinder floats on the river surface through a float plate. At the same time, river water enters the interior of the outer cylinder. As the river water enters the interior of the outer cylinder, the inner float rises due to the buoyancy of the water. At this time, a submersible pump works to extract the water from the interior of the outer cylinder. When the water level inside the outer cylinder decreases, the inner float descends. Through the reciprocating rise and fall of the inner float, the water flow around the outer cylinder and garbage enter the interior of the inner float.

[0018] S1. Float the outer cylinder on the river surface using a float plate. At this time, river water enters the interior of the outer cylinder.

[0019] S2. As river water enters the outer cylinder, the inner buoy rises due to the buoyancy of the water, and at the same time, the submersible pump operates.

[0020] S3. The submersible pump extracts water from the inside of the outer cylinder and uses the increase or decrease of water to drive the inner float to move up and down, so that the water and garbage around the outer cylinder can enter the interior of the inner float.

[0021] S4. The motor drives the gear column to rotate through the transmission connection between the pulley and the drive belt;

[0022] S5. The toothed column and teeth work together to drive the turntable to rotate. While the turntable is rotating, the toothed ring installed inside it works with the gear to drive the rotating rod and the cutter to cut the seamless garbage bag.

[0023] S6. While the garbage bag is being cut, the turntable drives the vertical rod and the fixing block to rotate, which in turn drives the hanging ring and the binding wire to circle around the garbage bag and tie it. At the same time, the electric push rod drives the push plate to move, pushing the tied garbage bag out of the outer cylinder through the sewage door.

[0024] Compared with the prior art, the present invention can achieve the following technical effects:

[0025] This application utilizes a shearing device and a strapping device installed inside the outer cylinder to assist in replacing the garbage bags inside the inner float. At the same time, a motor drives the strapping wires wound on the surface of the wire spool to tie the bottom of the garbage bag without cutting the strapping wires. After the garbage is packaged, the garbage bags float around the perimeter of the outer cylinder due to the limitation of the strapping wires, making it easier for workers to clean the garbage bags in a unified manner. This not only reduces labor intensity but also improves cleaning efficiency.

[0026] During the cleaning process, the motor drives the gear column to rotate through the transmission connection between the pulley and the drive belt. The gear column and the teeth mesh together to drive the turntable to rotate. During the rotation of the turntable, the turntable moves upward through the meshing of the wedge block and the wedge groove, separating from the gear. This prevents the cutter from rotating too much when the fixed block is binding the garbage bag, which would cause the cutter to affect the rotation of the turntable.

[0027] During the garbage cleanup, the outer cylinder floats on the river surface via a pontoon. Simultaneously, river water enters the interior of the outer cylinder. As the water enters, the inner pontoon rises due to the buoyancy of the water. At this time, a submersible pump operates to extract water from the interior of the outer cylinder. When the water level inside the outer cylinder decreases, the inner pontoon descends. Through the reciprocating rise and fall of the inner pontoon, water and garbage from the surrounding area of ​​the outer cylinder are drawn into the interior of the inner pontoon. This effectively cleans up floating garbage in the river and protects the habitat of aquatic life in the river. Attached Figure Description

[0040] Example

[0041] like Figure 1 A green ecological treatment and purification device for river water environment, including

[0042] Outer cylinder 100, float 110, garbage bag storage box 120, inner float 130, limiting plate 140 and submersible pump 150;

[0043] The self-cleaning mechanism 200 is installed on the top of the outer cylinder 100 and can assist in replacing the garbage bag;

[0044] like Figure 1 , Figure 2 and Figure 8 As shown, the float 110 is fixedly installed on the top of the outer cylinder 100, the garbage bag storage box 120 is installed on the top of the inner cavity of the outer cylinder 100, the inner float 130 is disposed inside the outer cylinder 100, the limiting plate 140 is fixedly installed between the outer cylinder 100 and the inner float 130, the submersible pump 150 is installed on the top of one side of the outer cylinder 100, and the water inlet of the submersible pump 150 is connected to the float 110; a fixing plate is fixedly installed on the surface of the inner float 130. 160. A sliding rod 170 is fixedly installed on the top of the limiting plate 140. The top end of the sliding rod 170 passes through the fixed plate 160 and is slidably connected to the fixed plate 160. A first spring 180 is installed on the bottom of the surface of the sliding rod 170. The first spring 180 is fixedly installed between the limiting plate 140 and the fixed plate 160. Through holes are opened at the bottom of the inner float 130 and the surface of the limiting plate 140. The water inlet end of the submersible pump 150 is located at the bottom of the limiting plate 140.

[0045] In this embodiment, the outer cylinder 100 floats on the river surface via the float plate 110. At the same time, river water enters the interior of the outer cylinder 100. As the river water enters the interior of the outer cylinder 100, the inner float 130 is lifted by the buoyancy of the water. At this time, the submersible pump 150 works to pump out the water inside the outer cylinder 100. When the water inside the outer cylinder 100 decreases, the inner float 130 is lowered. Through the reciprocating lifting and lowering of the inner float 130, water and garbage around the outer cylinder 100 are drawn into the interior of the inner float 130.

[0046] like Figure 2-6As shown, the self-cleaning mechanism 200 includes a shearer 210, a strapping device 220, a rectangular opening 230, and electric push rods 240. The shearer 210 is installed through the top of the outer cylinder 100 and can cut the garbage bag. The strapping device 220 is installed through the inside of the shearer 210 and can seal the cut garbage bag. The rectangular opening 230 is located on one side of the inner float 130. Two electric push rods 240 are installed through the bottom of one side of the inner float 130. Push plates are fixedly installed at the telescopic ends of the two electric push rods 240. A drain door is provided on the surface of the outer cylinder 100 and on one side of the rectangular opening 230. When the electric push rods 240 work, they drive the push plates to move, pushing the packaged garbage out of the outer cylinder 100 through the drain door. The shearer 210 includes an outer shell 211 installed through the top of the surface of the outer cylinder 100. A partition 212 is fixedly installed at the bottom of the inner cavity of the outer shell 211. A turntable 213 is rotatably mounted on the top of plate 212. The outer surface of the turntable 213 is provided with teeth 214, and the inner surface of the turntable 213 is provided with a toothed ring 215. A rotating rod 216 is installed through the surface of the partition plate 212. A cutter 217 is sleeved on the top of the surface of the rotating rod 216. A gear 218 is fixedly installed at the top of the rotating rod 216. The turntable 213 meshes with the gear 218 through the toothed ring 215. A motor 2101 is installed on one side of the outer shell 211. A connecting shaft is installed through the top of the partition plate 212. A toothed column 2104 is fixedly installed at one end of the connecting shaft at the top of the partition plate 212. Pulleys 2102 are fixedly installed at the output end of the motor 2101 and the bottom end of the connecting shaft. A transmission belt 2103 is wound around the surface of the two pulleys 2102. The two pulleys 2102 are connected by the transmission belt 2103. The toothed column 2104 meshes with the teeth 214.

[0047] In this embodiment, the motor 2101 drives the pulley 2102 to rotate, and the pulley 2102 drives the toothed column 2104 to rotate through the transmission belt 2103. The toothed column 2104 drives the turntable 213 to rotate through the engagement with the teeth 214. While rotating, the turntable 213 engages with the gear 218 through the toothed ring 215 installed inside, driving the rotating rod 216 and the cutter 217 to move, thereby cutting the seamless garbage bag.

[0048] A torsion spring 219 is fitted at the bottom of the rotating rod 216. The torsion spring 219 is connected to the bottom of the partition plate 212 and the bottom of the inner cavity of the outer shell 211. When the turntable 213 rises, the elasticity of the torsion spring 219 can drive the cutter 217 to reset, thus avoiding affecting the rotation of the turntable 213.

[0049] like Figure 3 , 6As shown in Figure 8, the strapping device 220 includes an inner baffle 221 fixedly installed inside the partition 212. The inner baffle 221 and the outer shell 211 together form an annular groove 222. A vertical rod 223 is fixedly installed on one side of the top of the turntable 213. The top end of the vertical rod 223 passes through the annular groove 222 and extends to the top of the outer shell 211. A fixing block 224 is fixedly installed on the top end of the vertical rod 223. A hanging ring 225 is fixedly installed on one side of the fixing block 224. A wire spool 226 is installed on one side of the top of the inner cavity of the outer cylinder 100. A binding wire 227 is wound around the surface of the wire spool 226. The end of the binding wire 227 away from the wire spool 226 passes through the hanging ring 225 and extends to the inner cavity of the inner float 130.

[0050] In this embodiment, while the turntable 213 moves, it drives the vertical rod 223 and the fixed block 224 to rotate, and simultaneously drives the hanging ring 225 and the binding wire 227 to circle around the garbage bag to tie the garbage bag. The bottom of the turntable 213 is provided with three wedge-shaped grooves 228, and the top of the partition plate 212 is fixedly installed with three wedge-shaped blocks 229 that are adapted to the wedge-shaped grooves 228. The wedge-shaped grooves 228 and the wedge-shaped blocks 229 are slidably connected. During the rotation of the turntable 213, the turntable 213 moves upward and separates from the gear 218 through the cooperation of the wedge-shaped blocks 229 and the wedge-shaped grooves 228.

[0051] In this embodiment, an annular guide rail 2201 is fixedly installed on the top of the inner cavity of the outer shell 211, and several telescopic rods 2202 are fixedly installed on the top of the turntable 213. The top end of the telescopic rod 2202 passes through the annular guide rail 2201 and extends into the interior of the annular guide rail 2201. A second spring 2203 is sleeved on the surface of the telescopic rod 2202, and the telescopic rod 2202 is slidably connected to the annular guide rail 2201. When the turntable 213 rotates, it can drive several telescopic rods 2202 to rotate inside the annular guide rail 2201 to maintain the stability of the turntable 213 during rotation and prevent the turntable 213 from shaking during rotation.

[0052] Working principle:

[0053] When cleaning up the garbage inside the river channel, the outer cylinder 100 floats on the surface of the river channel via the float plate 110. At the same time, river water enters the interior of the outer cylinder 100. As the river water enters the interior of the outer cylinder 100, the inner float 130 is lifted by the buoyancy of the water. At this time, the submersible pump 150 works to pump out the water inside the outer cylinder 100. When the water inside the outer cylinder 100 decreases, the inner float 130 is lowered. Through the reciprocating lifting and lowering of the inner float 130, the water flow and garbage around the outer cylinder 100 are drawn into the interior of the inner float 130.

[0054] When the garbage inside the inner float 130 is being cleaned, the motor 2101 drives the pulley 2102 to rotate. The pulley 2102, through the transmission belt 2103, drives the gear 2104 to rotate. The gear 2104, through its engagement with the teeth 214, drives the turntable 213 to rotate. Simultaneously, the turntable 213, through its internal gear ring 215 engaging with the gear 218, drives the rotating rod 216 and the cutter 217 to move, cutting the seamless garbage bag. While the turntable 213 is moving, it drives the vertical rod 223 and the fixed block 224 to rotate, which in turn drives the hanging ring 225 and the binding wire 227 to circle around the garbage bag and bind the garbage bag. At the same time, the electric push rod 240 works to drive the push plate to move, pushing the packaged garbage out of the outer cylinder 100 through the sewage door. Furthermore, by not cutting the binding wire 227, the packaged garbage bag can float around the outer cylinder 100 due to the limitation of the binding wire 227, making it easier for staff to clean.

[0055] It should be noted that the submersible pump 150 and motor 2101 mentioned above are all relatively mature existing components. The specific models can be selected according to actual needs. At the same time, the power supply of motor 2101 and submersible pump 150 can be powered by the built-in power supply or by the mains power supply. The specific power supply method can be selected according to the situation.

[0056] The above-mentioned green ecological governance and purification device for river water environment is used as follows: the shears and strappers installed inside the outer cylinder work together to assist in replacing the garbage bags inside the inner float. At the same time, the motor drives the strapping wires wound on the surface of the wire spool to tie the bottom of the garbage bags without cutting the strapping wires. After the garbage is packaged, the garbage bags float around the perimeter of the outer cylinder due to the limitation of the strapping wires, so that the garbage bags can be cleaned uniformly by the staff. This reduces the need for frequent cleaning by the staff, which not only reduces the labor intensity but also improves the cleaning efficiency.

[0057] During the cleaning process, the motor drives the gear column to rotate through the transmission connection between the pulley and the drive belt. The gear column and the teeth mesh together to drive the turntable to rotate. During the rotation of the turntable, the turntable moves upward through the meshing of the wedge block and the wedge groove, separating from the gear. This prevents the cutter from rotating too much when the fixed block is binding the garbage bag, which would cause the cutter to affect the rotation of the turntable.

[0058] During the garbage cleanup, the outer cylinder floats on the river surface via a pontoon. Simultaneously, river water enters the interior of the outer cylinder. As the water enters, the inner pontoon rises due to the buoyancy of the water. At this time, a submersible pump operates to extract water from the interior of the outer cylinder. When the water level inside the outer cylinder decreases, the inner pontoon descends. Through the reciprocating rise and fall of the inner pontoon, water and garbage from the surrounding area of ​​the outer cylinder are drawn into the interior of the inner pontoon. This process effectively cleans up floating garbage in the river and protects the habitat of aquatic life.

[0059] This invention also provides a green ecological treatment and purification method for river water environment:

[0060] S1. The outer cylinder 100 is floated on the surface of the river via the float plate 110. At this time, the river water enters the interior of the outer cylinder 100.

[0061] S2. As river water enters the outer cylinder 100, the inner buoy 130 is lifted by the buoyancy of the water, and at the same time, the submersible pump 150 is activated.

[0062] S3. The submersible pump 150 extracts water from the inside of the outer cylinder 100 and uses the increase or decrease of water to drive the inner float 130 to reciprocate up and down, so that the water flow and garbage around the outer cylinder 100 enter the interior of the inner float 130.

[0063] S4. The motor 2101 drives the gear 2104 to rotate through the transmission connection between the pulley 2102 and the transmission belt 2103.

[0064] S5, the toothed column 2104 and the tooth 214 work together to drive the turntable 213 to rotate. While the turntable 213 is rotating, it works with the gear 218 through the toothed ring 215 installed inside it to drive the rotating rod 216 and the cutter 217 to move, thereby cutting the unbroken garbage bag.

[0065] S6. While the garbage bag is being cut, the turntable 213 drives the vertical rod 223 and the fixing block 224 to rotate, which in turn drives the hanging ring 225 and the binding wire 227 to circle around the garbage bag and tie it. At the same time, the electric push rod 240 drives the push plate to move, and pushes the tied garbage bag out of the outer cylinder 100 through the sewage door.
