Description

Technical Field

[0001] The present application relates to the field of river channel cleaning devices, and in particular to a river channel cleaning device for garden ecological restoration. Background Art

[0002] In the garden's ecosystem, trees and plants follow the natural laws of growth. However, this process is also accompanied by the phenomenon of fallen leaves, broken branches and falling into the water. At the same time, when forest rangers are carrying out daily maintenance work, or when tourists are enjoying the beauty of the garden, they will inadvertently drop garbage into the water. The accumulation of garbage caused by these natural and human factors has seriously polluted the river environment. The river cleaning device used for garden ecological restoration is specially designed for the garden ecosystem. It is used to clean up garbage, pollutants, etc. in the river within the garden area, helping the river to restore its ecological function and improve the water quality.

[0003] Currently, the cleaning of floating garbage in rivers mostly relies on manual salvage and electric cleaning equipment. Salvors need to hold tools and work repeatedly, which is inefficient and intensive. In addition, floating garbage is difficult to collect and transport efficiently. Salvaged garbage tends to fall back into the river, resulting in poor cleaning effects. Existing electric cleaning equipment (such as boat-shaped cleaning equipment that uses electric propulsion boats to navigate in rivers and collect floating garbage into storage compartments on board through collection devices) has high operating costs and limited processing capacity. It is often unable to cope with large amounts of complex floating garbage and is difficult to clean quickly and thoroughly. In addition, its single function makes it difficult to take into account water purification. Summary of the Invention

[0014] By adopting the above technical solutions, the medicine guiding plate guides the medicine in the medicine box to be sprayed out by the nozzles. The foam board adjusts the amount of medicine. The limiting blocks cooperate with the chain wheels II and the bevel gear III to realize power transmission to drive related components. The sleeve rods provide the power for the foam board to reset. The second roller chain makes the plurality of chain wheels II linked together to jointly control the plurality of limiting blocks in the medicine box and assist in realizing the medicine delivery.

[0029] The following further elaborates on this application in conjunction with the attached Figures 1 - 12 for a more detailed description of this application.

[0030] The embodiment of this application discloses a river cleaning device for garden ecological restoration.

[0031] Refer to Figure 1 、 Figure 3A river cleaning device for garden ecological restoration includes a weir net 1 and a power mechanism 2 that is movably arranged on the back surface of the weir net 1. The power mechanism 2 is the power source of the entire device. The bottom end of the power mechanism 2 is fixed with a steel column 1 that is inserted into the bottom of the riverbed 12. The steel column 1 keeps the power mechanism 2 stable during operation or under the impact of water flow. The two sides of the weir net 1 are V-shaped mesh surfaces inclined at 30 degrees. A collection area 14 is provided in the middle of the weir net 1. The collection area 14 is rectangular (the shape and position of the collection area 14 are as shown in FIG. Figure 1 As shown), the garbage is guided to the collection area 14 by tilting the mesh surfaces at both ends of the weir net 1. The weir net 1 is made of stainless steel metal mesh (mesh size 10 mm×10 mm), which is corrosion-resistant and can maintain structural integrity for a long time in the complex and changeable river water environment. It is durable. The floating garbage is guided to the collection area 14 for centralized treatment at both ends of the weir net 1. A cleaning mechanism 3 is movably provided at one end of the weir net 1. The cleaning mechanism 3 is used to fish the floating garbage in the collection area 14 out of the water. A plurality of steel columns stably inserted into the bottom of the riverbed 12 are provided at the bottom of the weir net 1. The steel columns are used to keep the weir net 1 stable under the impact of water flow. A garbage conveying mechanism 5 is movably provided on one side of the cleaning mechanism 3.

[0032] If the riverbed is a rock or hard concrete structure, the device base can be fixed by expansion bolts and embedded parts; if it is a soft mud and sand riverbed, pile-driven steel pipe piles are used in conjunction with cable reinforcement structure to improve overall stability and adapt to various geological conditions.

[0033] Before using the device, the two ends of the weir net 1 are fixed on the riverbed 12 on both sides of the river channel, the power mechanism 2 is fixed in the middle of the river channel on the back side of the weir net 1, the lower end of the water wheel body 202 is sunk into the water, and the blade 203 located at the bottom is in contact with the water surface, the cleaning mechanism 3 is fixed on the riverbed 12 on the side where the garbage collection box 13 is set, and the cleaning plate 303 located at the bottom is completely sunk into the water, and the garbage intercepting mechanism 6 is installed on the riverbed 12 on the same side of the cleaning mechanism 3. The garbage intercepting mechanism 6 is located between the cleaning mechanism 3 and the garbage collection box 13, so that the collection area 14 is on the outside of the cleaning mechanism 3, the power mechanism 2 is in the middle of the back water surface of the dam net 1, the spraying mechanism 4 is installed at the upper end of the back water surface of the dam net 1 and the collection area 14, the garbage intercepting mechanism 6 is installed on the front water surface of the dam net 1, and the garbage collection box 13 is placed in a rectangular groove opened on the riverbed 12 on one side thereof. During the flood season of the river, a reducer can be installed at the power mechanism 2 to avoid excessive water flow affecting the operation of the device.

[0034] The garbage conveying mechanism 5 is used to transport the floating garbage fished out by the cleaning mechanism 3. The upper end of the backwater surface of the river blocking net 1 is fixedly provided with a medicine spraying mechanism 4, which is used to sprinkle water quality improving drugs such as flocculants on the water flow after garbage cleaning. A garbage interception mechanism 6 is movably arranged on one side of the water-facing surface of the river blocking net 1. The garbage interception mechanism 6 is located 3 meters upstream of the river blocking net 1 and is used to initially intercept and collect floating garbage such as branches and fallen leaves floating in the river. Fixed piles 7 are fixed at both ends of the river blocking net 1, and the bottom ends of the two fixed piles 7 are fixed on the riverbeds 12 on both sides of the river. A rectangular groove is opened in the riverbed 12 below the garbage conveying mechanism 5. The rectangular groove is opposite to the end of the conveyor belt 503. A garbage collection box 13 is arranged in the rectangular groove. A winch or a lifting ring is arranged on the top of the garbage collection box 13 for subsequent cleaning. The garbage collection box 13 is used to store the floating garbage intercepted or fished out by the garbage interception mechanism 6 and the cleaning mechanism 3.

[0035] During use, put water quality improving drugs such as flocculants inside the medicine spraying mechanism 4. When the natural water flow in the river flows, when driving the floating garbage on the water surface to the garbage interception mechanism 6, the conveyor belt 604 and the hooks 605 on the surface of the conveyor belt 604 intercept the larger floating garbage such as residual branches and fallen leaves in the river. The omitted floating garbage flows through the gaps between the conveyor belts 604 along with the water flow to the river blocking net 1 and is guided by the river blocking net 1 to the collection area 14. When the natural water flow passes through the blades 203, the blades 203 rotate to drive the power mechanism 2 to operate, so that the roller shaft 603 drives the conveyor belt 604 to rotate, transporting the floating garbage intercepted by the foam board 404 to the garbage collection box 13, making the cleaning board 303 pick up the floating garbage and convey it into the garbage collection box 13 through the garbage interception mechanism 6. At the same time, it drives the medicine spraying mechanism 4 to operate, making the medicine intermittently sprinkle on the water surface to treat the water quality of the water flow after filtering the floating garbage. When the water flow stops flowing, the medicine spraying action stops. This device is applicable to small and medium-sized rivers with a width of 5 - 15 meters, an average water depth of not less than 0.5 meters, and continuous water flow throughout the year, especially applicable to ecological restoration demand scenarios such as urban garden landscape water systems and wetland park drainage channels, and can also be modularly expanded according to on-site requirements.

[0036] Refer to Figure 4, the power mechanism 2 includes a first fixed seat 201 and a water wheel shaft 204 rotatably provided at the upper end of the first fixed seat 201. A water wheel main body 202 is rotatably provided in the middle of the first fixed seat 201. The water wheel shaft 204 passes through the upper end of the first fixed seat 201 and the middle of the water wheel main body 202. One end of the water wheel shaft 204 close to the spraying mechanism 4 is fixedly provided with a first transmission shaft 205. A first bevel gear 207 is fixedly sleeved at one end of the first transmission shaft 205 close to the spraying mechanism 4. A plurality of blades 203 are circumferentially distributed in the middle of the water wheel shaft 204 between the first fixed seats 201. Both ends of the plurality of blades 203 are respectively fixed to both sides of the inner wall of the water wheel main body 202; One end of the water wheel shaft 204 away from the first transmission shaft 205 is fixedly provided with a second transmission shaft 206. A base 8 is fixedly sleeved at one end of the second transmission shaft 206 away from the water wheel shaft 204. The bottom end of the base 8 is fixed on the riverbed 12. A first sprocket 9 is provided at one end of the second transmission shaft 206 close to the base 8. The first sprocket 9 is fixedly sleeved on the outside of the second transmission shaft 206 between the base 8 and the water wheel shaft 204.

[0037] When natural water flow passes through the surface of the blade 203, it pushes the blade 203 and the water wheel main body 202 to rotate around the water wheel shaft 204, drives the water wheel shaft 204 to rotate, and then drives the first transmission shaft 205 and the second transmission shaft 206 to rotate, thereby driving the first bevel gear 207 and the first sprocket 9 to rotate. Because the first bevel gear 207 meshes with a second sprocket 412, and the first sprocket 9 and a third sprocket 607 are externally meshed with a first roller chain 10, the first bevel gear 207 and the third sprocket 607 are driven to rotate simultaneously, realizing the transmission of power.

[0038] Refer to Figure 5 , Figure 6 , the cleaning mechanism 3 includes a second fixed seat 301 and a turntable 302 movably provided at one end of the second fixed seat 301. The lower end of the side of the second fixed seat 301 away from the turntable 302 is fixed on the riverbed 12. A third transmission rod 313 is rotatably provided at the upper end of the second fixed seat 301 and the middle of the turntable 302. The third transmission rod 313 passes through the upper end of the second fixed seat 301 and the middle of the turntable 302. A second bevel gear 314 is fixedly sleeved at one end of the third transmission rod 313 close to the spraying mechanism 4. The teeth on the surface of the second bevel gear 314 mesh with the teeth on the surface of the third bevel gear 407. A fixing ring 310 is fixedly sleeved at one end of the third transmission rod 313 away from the spraying mechanism 4. A fixing ring 310 is provided in the middle of the side of the turntable 302 facing away from the second fixed seat 301. The fixing ring 310 is fixedly sleeved at one end of the third transmission rod 313 away from the spraying mechanism 4. A plurality of rotating rods 304 are circumferentially distributed on the outside of the fixing ring 310. A cleaning plate 303 is rotatably provided at one end of each of the plurality of rotating rods 304 away from the fixing ring 310. A plurality of racks are provided on the surface of the cleaning plate 303, which is convenient for fishing up the floating garbage on the river surface.

[0039] The rotation of the third transmission rod 313 drives the fixed ring 310 and multiple rotating rods 304 to rotate in the middle of the turntable 302. Multiple first rotating shafts 308 and multiple cleaning plates 303 rotate simultaneously, driving multiple second support rods 307 to deflect, and further driving multiple sliding rods 309 to slide inside the annular groove 306. At the same time, since a second rotating shaft 311 is fixedly provided at one end of each cleaning plate 303 facing away from the rotating rod 304, and both ends of multiple first support rods 305 are sleeved on the corresponding second rotating shafts 311 of each group, each cleaning plate 303 always maintains a horizontal state.

[0040] Multiple second support rods 307 are movably arranged on one side of multiple rotating rods 304 facing away from the cleaning plates 303. A first rotating shaft 308 is fixed on one side of the cleaning plate 303 close to the rotating rod 304. One end of the first rotating shaft 308 is fixed to the middle of the cleaning plate 303, and the other end of the first rotating shaft 308 penetrates through one end of the second support rod 307 close to the cleaning plate 303. An annular groove 306 is formed in the outer ring of one side of the turntable 302 facing away from the second fixed seat 301. Multiple sliding rods 309 are slidably arranged inside the annular groove 306. The part of the sliding rod 309 located inside the annular groove 306 is an arc-shaped block adapted to the shape of the annular groove 306. Both ends of the second support rod 307 are respectively rotatably sleeved on the first rotating shaft 308 and the sliding rod 309. Multiple cleaning plates 303 are grouped in pairs. One first support rod 305 is movably arranged on one side of each group of cleaning plates 303 away from the rotating rod 304. A second rotating shaft 311 is fixedly provided at one end of each cleaning plate 303 facing away from the rotating rod 304. The number of second rotating shafts 311 is the same as the number and number of groups of cleaning plates 303 in the same group. Both ends of multiple first support rods 305 are movably sleeved on the second rotating shafts 311 of the corresponding group; One end of the third transmission rod 313 close to the second bevel gear 314 is fixedly sleeved with a first spur gear 312. The specific position of the first spur gear 312 on the third transmission rod 313 on the side of the cleaning plate 303 facing away from the turntable 302 (such as Figure 5 shown).

[0041] When one cleaning plate 303 rotates to the upper end of the tooth block 505, since the racks on the surface of the cleaning plate 303 and the surface of the tooth block 505 are staggered, when the cleaning plate 303 passes through the tooth block 505, the floating garbage on the top surface of the cleaning plate 303 is exchanged to the surface of the tooth block 505. Due to the gravity of the floating garbage itself and the sliding force of the attached water on the surface of the guide plate 504, the floating garbage flows onto the surface of the first conveyor belt 503.

[0042] Refer to Figures 7 - 10, the medicine spraying mechanism 4 includes a medicine box 401 and a plurality of nozzles 402 (the aperture of the nozzles 402 is 1 mm) fixedly arranged at the bottom end of the medicine box 401. The plurality of nozzles 402 are linearly arranged to cover three-quarters of the river-blocking net 1. One side of the medicine box 401 close to the river-blocking net 1 is fixed to the upper end of the back water surface of the river-blocking net 1. The nozzles 402 are used to spray water-quality improving drugs such as flocculants onto the water surface. A plurality of circular holes 408 are formed in the middle of the inner bottom surface of the medicine box 401 above the nozzles 402. The plurality of circular holes 408 are respectively communicated with the tops of the plurality of nozzles 402. The number of the circular holes 408 is the same as that of the nozzles 402. A medicine guiding plate 403 is fixedly arranged at the lower end inside the medicine box 401. The medicine guiding plate 403 is used to guide the flow of solid or liquid drugs into the nozzles 402. A foam board 404 is movably arranged on one side of the inner bottom surface of the medicine box 401. The foam board 404 is located below the medicine guiding plate 403, and the top end of the foam board 404 abuts against the bottom end of the medicine guiding plate 403. The foam board 404 seals the plurality of circular holes 408 in the initial state; fixing plates one 411 are arranged at the bottom end of the medicine box 401 close to the third transmission rod 313 and at the bottom end of the medicine box 401 close to the first bevel gear 207. One end of the third transmission rod 313 close to the medicine spraying mechanism 4 rotates through one side of one fixing plate one 411 facing the cleaning mechanism 3, and one end of the first transmission shaft 205 close to the medicine box 401 rotates through one side of the other fixing plate one 411 facing the first transmission shaft 205.

[0043] The rotation of the first bevel gear 207 drives the rotation of the third bevel gear 407 close to the first transmission shaft 205. Since the second roller chain 417 meshes with the outer sides of the second sprockets 412, the first bearing 413, the third bearing 415 and the fourth bearing 416, the plurality of second sprockets 412 and the third bevel gear 407 close to the cleaning mechanism 3 rotate, causing the plurality of limit blocks 406 to rotate simultaneously.

[0044] A plurality of limiting blocks 406 are rotatably and penetratingly arranged on the inner bottom surface of the medicine box 401 on the side away from the foam board 404. Convex blocks are arranged on the outer sides of the upper ends of the plurality of limiting blocks 406. Chain wheels two 412 are fixedly sleeved on the middles of the plurality of limiting blocks 406 located outside the medicine box 401. At the bottom ends of the limiting block 406 near one end of the cleaning mechanism 3 and the limiting block 406 near the transmission shaft one 205 at the bending part of the medicine box 401, bevel gears three 407 are fixedly sleeved. The teeth on the surface of the bevel gear three 407 near one end of the cleaning mechanism 3 are meshed with the teeth on the surface of the bevel gear two 314; A plurality of sleeve rods 405 are fixedly arranged at the lower end of one side of the inner wall of the medicine box 401. The plurality of sleeve rods 405 are located on the side of the foam board 404 facing away from the limiting block 406. Pressing rods 409 are movably arranged inside the plurality of sleeve rods 405. Springs 410 are sleeved on the surfaces of the plurality of pressing rods 409 (the calculation formula for the elastic force of the spring 410 is F = kx, where F represents the elastic force of the spring 410, k represents the constant of the spring 410, and x represents the compression amount of the spring 410). The two ends of the spring 410 are respectively fixed to the inner wall of the sleeve rod 405 and the outer wall of the pressing rod 409. The end of the pressing rod 409 close to the foam board 404 is fixed to the surface of the foam board 404.

[0045] When the convex block on the surface of the limiting block 406 rotates to the position of the foam board 404, the foam board 404 is extruded, causing the foam board 404 to move horizontally, the pressing rod 409 to move towards the sleeve rod 405, the spring 410 to be compressed, and at the same time, the circular hole 408 to be exposed. As a result, the medicine at the upper end inside the medicine box 401 flows through the circular hole 408 along the inclined surface of the medicine guiding plate 403 into the nozzle 402, and then the medicine is scattered onto the water surface.

[0046] Between the three chain wheels two 412 at the bottom end of the medicine box 401 near one end of the cleaning mechanism 3, a bearing one 413 and a bearing three 415 are arranged. The tops of the bearing one 413 and the bearing two 414 are fixed to the bottom end of the medicine box 401. At the corner position of the bending part of the medicine box 401 near the transmission shaft one 205, a bearing three 415 is arranged. The top of the bearing three 415 is fixed to the bottom end of the medicine box 401. The second roller chain 417 successively bypasses the bearing one 413, the bearing two 414, the bearing three 415, and the plurality of chain wheels two 412, and the chain links of the second roller chain 417 are meshed with the tooth grooves of the plurality of chain wheels two 412 (the specific shape of the second roller chain 417 is as Figure shown).

[0047] After one medicine spraying is completed, the convex block on the surface of the limiting block 406 continues to rotate and separates from the surface of the foam board 404, causing the spring 410 to rebound and drive the pressing rod 409 and the foam board 404 to reset, thereby sealing the circular hole 408. Through the contact and separation actions of the convex block on the surface of the limiting block 406 and the foam board 404, the medicine spraying mechanism 4 realizes an automatic intermittent quantitative medicine spraying action.

[0048] Reference ​ , ​ , ​ , the garbage conveying mechanism 5 includes a third fixed seat 501 and a first roller 502 rotatably arranged inside both ends of the third fixed seat 501. The bottom end of the third fixed seat 501 close to one side of the riverbed 12 is fixed on the riverbed 12. One end of the first roller 502 close to the cleaning mechanism 3 is fixedly sleeved with a second spur gear 506. The second spur gear 506 and the first spur gear 312 are on the same horizontal line. A toothed belt 11 (the width of the toothed belt 11 is 200 mm) is sleeved outside the second spur gear 506 and the first spur gear 312. The teeth inside the toothed belt 11 mesh with the teeth on the surfaces of the second spur gear 506 and the first spur gear 312.

The rack on the surface of the tooth block 505 and the rack on the surface of the cleaning plate 303 are arranged in a staggered manner.

[0049] When the floating garbage flows onto the surface of the first conveyor belt 503, since the second spur gear 506 and the first spur gear 312 are externally meshed with the toothed belt 11, the rotation of the third transmission rod 313 drives the two first rollers 502 to rotate, and then drives the non-first conveyor belt 503 to rotate, so that the floating garbage on the surface of the first conveyor belt 503 is transported into the garbage collection box 13.

[0050] Reference ​ , the garbage interception mechanism 6 includes two fixed columns 601 and a second fixing plate 602 fixedly arranged at the top ends of the two fixed columns 601. The bottom ends of the two fixed columns 601 are fixed to the surfaces of the riverbeds 12 on both sides of the river channel. A plurality of second rollers 603 are rotatably arranged at the bottom end of the second fixing plate 602. Three fixed columns 601 are equally sleeved outside the plurality of second rollers 603. A rack is arranged inside the three fixed columns 601. A number of tooth grooves are circumferentially distributed on the surfaces of the plurality of second rollers 603 at the three second conveyor belts 604. The rack inside the fixed column 601 meshes with the tooth grooves on the surface of the second roller 603. And stoppers for preventing the second conveyor belt 604 from falling off or shifting in position are arranged at both positions of the second roller 603 on both sides of the second conveyor belt 604.

[0051] The rotation of the third sprocket 607 drives the fourth transmission rod 606 to rotate on the upper end of one of the second rollers 603. Since the fourth bevel gear 608 and the fifth bevel gear 609 are meshed, the second roller 603 close to the fourth transmission rod 606 is driven to rotate.

[0052] The surfaces of the three fixed columns 601 are evenly distributed with a number of hooks 605, which are used to initially intercept floating garbage such as fallen leaves and branches in the river and convey it to the garbage collection bin 13. At the upper end of one of the fixed columns 601, a fourth transmission rod 606 is rotatably arranged. The fourth transmission rod 606 penetrates through the upper end of one of the fixed columns 601. At both ends of the fourth transmission rod 606, a third sprocket 607 and a fourth bevel gear 608 are respectively fixedly sleeved. At the upper end of the second roller 603 near one end of the fourth transmission rod 606, a fifth bevel gear 609 is fixedly sleeved. The teeth on the surface of the fifth bevel gear 609 mesh with the teeth on the surface of the fourth bevel gear 608. The third sprocket 607 and the first sprocket 9 are on the same horizontal line. A first roller chain 10 is sleeved outside the third sprocket 607 and the first sprocket 9. The first roller chain 10 successively bypasses the third sprocket 607 and the first sprocket 9, and the links of the first roller chain 10 mesh with the tooth grooves of the third sprocket 607 and the first sprocket 9.

[0053] The second conveyor belt 604 and multiple second rollers 603 are rotated simultaneously to move a number of hooks 605 synchronously, so as to convey larger floating garbage such as fallen leaves and branches in the river into the garbage collection bin 13, and the staff regularly cleans the garbage in the garbage collection bin 13.

[0054] The implementation principle of the river cleaning device for garden ecological restoration in the embodiment of the present application is as follows: Before the device is used, each component is fixed at specific positions on both sides and in the middle of the river. During the flood season, a speed reducer can be installed at the power mechanism 2. When in use, the natural water flow drives the floating garbage to flow to the garbage interception mechanism 6. The second conveyor belt 604 and the hooks 605 intercept larger floating garbage. The floating garbage that is missed flows through the guiding of the river blocking net 1 into the collection area 14. Flocculants and other water purification drugs are placed inside the medicine spraying mechanism 4. When the water flow passes through the blades 203, it pushes the blades 203 and the water wheel main body 202 to rotate around the water wheel shaft 204, driving the first transmission shaft 205 and the second transmission shaft 206 to rotate, and further driving the first bevel gear 207 and the first sprocket 9 to rotate, so that the floating garbage intercepted by the second conveyor belt 604 is moved into the garbage collection bin 13. At the same time, it drives the limit block 406 to rotate and perform actions such as squeezing and resetting the foam board 404, realizing automatic intermittent quantitative medicine spraying of the medicine spraying mechanism 4. At the same time, the cleaning plate 303 rotates around the third transmission rod 313 and maintains a horizontal state. When the cleaning plate 303 rotates and passes through the tooth block 505, the floating garbage falls onto the tooth block 505 and slides onto the surface of the first conveyor belt 503. The rotation of the third transmission rod 313 drives the first roller 502 and the first conveyor belt 503 to rotate, so that the floating garbage is conveyed into the garbage collection bin 13, and the staff regularly cleans the garbage in the garbage collection bin 13.
