Description

Technical Field

[0001] This invention belongs to the field of river and lake water purification technology, and more specifically, relates to an ecological purification device for river and lake water. Background Technology

[0002] With urban development and industrial expansion, pollution of rivers and lakes in my country has become increasingly serious. A lot of garbage floats on the surface of rivers and lakes, with plastic waste accounting for a large proportion. This pollution is significant, affecting not only the ecological environment of rivers and lakes but also the organisms within them, thus impacting the overall ecology of rivers and lakes.

[0003] To address the impact of floating garbage in rivers and lakes, manual cleaning is typically used, but this is frequent, inconvenient, and dangerous. Therefore, many rivers and lakes now employ garbage collectors for cleaning. Simply place the collector in the water to collect floating garbage from the surrounding area. A connected water pump creates negative pressure inside the collector, generating a water level difference. The surrounding floating garbage is continuously drawn into the collector along with the water, concentrating in the inner tank. The garbage inside is then pumped out, and the process is repeated. After a period of time, the inner tank of the collector can be removed.

[0004] However, when the garbage collector is collecting floating garbage on the water surface, some large floating garbage such as plastic bottles will also enter the garbage collector with the water flow. This will cause the inner tank of the collector to fill up quickly, which will increase the number of times the inner tank needs to be cleaned, which is time-consuming and laborious. Moreover, some large garbage will block or get stuck in the garbage inlet of the collector, thus affecting the collection of other garbage and affecting the effectiveness of the collector.

[0005] Therefore, it is necessary to provide an ecological purification device for river and lake water to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an ecological purification device for river and lake water to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A river and lake water quality ecological purification device includes a garbage collector, and also includes:

[0009] A support plate is provided above the waste collector, and multiple interference mechanisms are provided below the support plate. The multiple interference mechanisms are located around the waste collector to prevent large waste from entering the waste collector.

[0010] A transmission mechanism, mounted on the support plate, is used to drive the multiple interference mechanisms to rotate synchronously.

[0011] A collection box, connected to the support plate, is used to collect large debris from the water surface. The collection box is equipped with a conveying mechanism to allow large debris from the water surface to enter the collection box.

[0012] As a further aspect of the present invention: the interference mechanism includes:

[0013] A rotating shaft is rotatably mounted on the support plate via a bearing, and an external gear is provided at the upper end of the rotating shaft;

[0014] A fixing block is disposed at the lower end of the rotating shaft, and multiple interference plates are disposed on the side of the fixing block.

[0015] As a further aspect of the present invention: a bracket is provided at the upper end of the support plate, and the transmission mechanism includes:

[0016] A ring plate is rotatably mounted on the support plate. The inner and outer sides of the ring plate are respectively provided with an inner tooth block and an outer tooth block, and the outer tooth block meshes with the external gear.

[0017] The first rotating rod is rotatably mounted on the bracket via a bearing. The first rotating rod is provided with an internal gear that meshes with the internal gear block. When the conveying mechanism operates, it simultaneously drives the first rotating rod to rotate.

[0018] As a further aspect of the present invention: the conveying mechanism includes:

[0019] Support plates are provided on the collection box, and there are two of them. Multiple rotating columns are rotatably arranged between the two support plates. Conveying wheels are provided on the rotating columns, and conveyor belts are driven to the conveying wheels to move large garbage on the water surface.

[0020] A drive component, mounted on the collection box, is used to drive the rotating column to rotate.

[0021] As a further aspect of the present invention: the driving component includes:

[0022] A fixing plate is disposed on the collection box, and a second rotating rod is rotatably mounted on the fixing plate via a bearing. A worm gear is disposed on the second rotating rod.

[0023] A worm gear is disposed at one end of the rotating column and meshes with the worm wheel; the collection box is provided with a driving component that is connected to the other end of the rotating column.

[0024] A linkage component connects the second rotating rod to the first rotating rod, so that when the second rotating rod rotates, it simultaneously drives the first rotating rod to rotate.

[0025] As a further aspect of the present invention: the linkage component includes a first pulley disposed on the first rotating rod and a second pulley disposed on the second rotating rod, and a transmission belt is drivingly connected between the first pulley and the second pulley.

[0026] As a further aspect of the present invention: a base plate is evenly arranged on the conveyor belt, a baffle is movably inserted into the base plate, a limiting component for fixing the baffle is provided on the base plate, and a plurality of water filter holes are opened through the conveyor belt.

[0027] As a further aspect of the present invention: a limiting hole is provided on the baffle, and the limiting component includes a limiting rod that movably passes through the side wall of the base plate and is adapted to the limiting hole. A pull block is provided at the outer end of the limiting rod, and an elastic element is provided between the pull block and the base plate.

[0028] As a further aspect of the present invention: an adjusting post is movably inserted inside the rotating shaft, the lower end of the adjusting post is connected to the fixed block, and a screw for limiting the adjusting post is threaded onto the rotating shaft.

[0029] As a further embodiment of the present invention: the lower end of the support plate is provided with an outer rod, an inner rod is movably inserted inside the outer rod, a hook is provided at the lower end of the inner rod, a plurality of fixing holes are opened on the outer wall of the inner rod, and fixing bolts that are adapted to the fixing holes are provided on the outer rod.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. In this solution, the transmission mechanism drives multiple interference mechanisms to rotate simultaneously. Smaller floating debris around the garbage collector will enter the inner tank with the water flow, while larger floating debris, such as plastic bottles, will be blocked by the interference mechanisms. The rotation of these interference mechanisms will also cause large debris like plastic bottles to move around the garbage collector. The conveying mechanism will then carry this large floating debris into the collection bin. This prevents large debris like plastic bottles from entering the garbage collector, thus preventing it from filling up quickly and significantly reducing the frequency of manual cleaning, saving considerable manpower and extending the collector's operating time. Furthermore, it prevents large debris like plastic bottles from blocking or getting stuck at the garbage collector's inlet, greatly minimizing interference with the collection of other small floating debris and significantly improving the collection and cleaning effect of garbage on river and lake surfaces, thereby effectively improving the water quality of rivers and lakes.

[0032] 2. In this solution, the hook can be used to hook the pull bar on the inner liner of the garbage collector. When the collection box and support plate are lifted by external equipment, the inner liner of the garbage collector will also be lifted and rotated horizontally through the hook. The staff can easily clean the inner liner of the garbage collector, saving time and effort, reducing the complexity of operation and avoiding danger.

[0033] 3. In this solution, baffles can support and block large waste such as plastic bottles on the conveyor belt. The baffles can be adjusted and replaced as needed. When replacing, the baffle is inserted into the base plate and then fixed by limiting components. Attached Figure Description

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1 , Figure 3 , Figure 5 and Figure 7 A river and lake water quality ecological purification device includes a garbage collector 1, and further includes: a support plate 2, which is disposed above the garbage collector 1, and multiple interference mechanisms 3 are disposed below the support plate 2. The multiple interference mechanisms 3 are located around the garbage collector 1 to prevent large garbage from entering the garbage collector 1; a transmission mechanism 4, which is disposed on the support plate 2 to drive the multiple interference mechanisms 3 to rotate synchronously; and a collection box 5, which is connected to the support plate 2 to collect large garbage on the water surface. The collection box 5 is provided with a conveying mechanism 6 to allow large garbage on the water surface to enter the collection box 5.

[0047] In use, this device can be connected to the collection box 5 via external equipment, which can drive the collection box 5 and the support plate 2 to be lifted vertically and rotated horizontally, thus facilitating the installation and subsequent cleaning of the device. The support plate 2 of this device is placed above the surface garbage collector 1, so that multiple interference mechanisms 3 are located around the collection port of the garbage collector 1, and the bottom of the interference mechanism 3 is at a distance above the water surface and does not touch the water surface. Then the equipment can be started, activating the conveying mechanism 6 and the transmission mechanism 4. The transmission mechanism 4 will drive multiple interference mechanisms 3 to rotate simultaneously. When the garbage collector 1 is in use, smaller floating garbage around it will enter the inner tank of the garbage collector 1 with the water flow, while larger floating garbage, such as plastic bottles, will be blocked by the interference mechanisms 3, preventing them from entering the inner tank of the garbage collector 1. Furthermore, the rotation of the interference mechanisms 3 will cause large garbage such as plastic bottles to move around the garbage collector 1. When they reach the position of the conveying mechanism 6, the conveying mechanism 6 can carry the large floating garbage such as plastic bottles on the water surface into the collection box 5. That is, the collection box 5 collects the large floating garbage such as plastic bottles, achieving the ecological purification effect of rivers and lakes. This prevents large trash such as plastic bottles from entering the trash collector 1, thus preventing it from filling up quickly and greatly reducing the frequency of manual cleaning. This saves a lot of manpower and extends the working time of the trash collector 1. It also prevents large trash such as plastic bottles from blocking or getting stuck at the entrance of the trash collector 1, greatly preventing it from affecting the collection of other small floating trash. This greatly improves the collection and cleaning effect of trash on the river and lake surface, effectively improving the water quality of the river and lake and achieving good ecological purification.

[0048] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 5-6The lower end of the support plate 2 is also equipped with an outer rod 15, inside which an inner rod 16 is movably inserted. A hook 17 is provided at the lower end of the inner rod 16, and multiple fixing holes 18 are formed on the outer wall of the inner rod 16. Fixing bolts 19, which are compatible with the fixing holes 18, are provided on the outer rod 15. The hook 17 can hook onto the pull bar on the inner liner of the garbage collector 1. When the collection box 5 and the support plate 2 are subsequently lifted by external equipment, the hook 17 will also lift the inner liner of the garbage collector 1, causing it to detach from the garbage collector 1. Then, by rotating the external equipment horizontally, the inner liner of the garbage collector 1 will move along with it. Afterwards, workers can easily clean the inner liner of the garbage collector 1 from the shore, saving time and effort, reducing operational complexity, and avoiding danger. After cleaning, the inner liner is rotated back to the garbage collector 1 and lowered back in. By loosening the fixing bolt 19, the inner rod 16 can move along the outer rod 15. The inner rod 16 will then move the hook 17, thereby adjusting the height of the hook 17. This adjustment can be made in conjunction with the inner liner of the garbage collector 1 according to specific usage conditions, making it widely applicable and highly flexible. After adjustment, tighten the fixing bolt 19.

[0049] In this embodiment, preferably, please refer to [reference needed]. Figure 1 , Figure 3 and Figure 5 The interference mechanism 3 includes: a rotating shaft 31, which is rotatably mounted on the support plate 2 via bearings, with an external gear 32 at the upper end of the rotating shaft 31; and a fixing block 33, which is located at the lower end of the rotating shaft 31, with multiple interference plates 34 on its side. The transmission mechanism 4 drives the rotating shaft 31 to rotate, which in turn drives the fixing block 33 and the interference plates 34 to rotate. When the interference plates 34 rotate, they interfere with large waste such as plastic bottles, preventing them from entering the waste collector 1, and causing the large waste such as plastic bottles to move around the waste collector 1.

[0050] An adjusting column 13 is movably inserted inside the rotating shaft 31. The lower end of the adjusting column 13 is connected to the fixed block 33. A screw 14 for limiting the adjusting column 13 is threaded onto the rotating shaft 31. When the screw 14 is loosened, the adjusting column 13 can slide up and down along the rotating shaft 31. The adjusting column 13 will then move the interference plate 34, thereby adjusting the height of the interference plate 34. It can be adjusted according to different actual use sites, and is highly flexible.

[0051] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 3-4The upper end of the support plate 2 is provided with a bracket 7. The transmission mechanism 4 includes: a ring plate 41, rotatably mounted on the support plate 2, with an inner tooth block 42 and an outer tooth block 43 respectively provided on the inner and outer sides of the ring plate 41, the outer tooth block 43 meshing with an outer gear 32; and a first rotating rod 44, rotatably mounted on the bracket 7 via a bearing, with an inner gear 45 meshing with the inner tooth block 42 on the first rotating rod 44. When the conveying mechanism 6 operates, it simultaneously drives the first rotating rod 44 to rotate. Starting the conveying mechanism 6 simultaneously drives the first rotating rod 44 to rotate, which in turn drives the inner gear 45 to rotate. The inner gear 45 then drives the ring plate 41 to rotate via the inner tooth block 42. When the ring plate 41 rotates, it simultaneously drives multiple meshing outer gears 32 to rotate via the outer tooth block 43. The rotation of the outer gears 32 drives the rotating shaft 31 to rotate, which in turn drives the fixed block 33 and the interference plate 34 to rotate.

[0052] In this embodiment, preferably, please refer to [reference needed]. Figure 1-2 and Figure 7-8 The conveying mechanism 6 includes: two support plates 61 mounted on the collection box 5; multiple rotating columns 62 rotatably mounted between the two support plates 61; conveyor wheels 63 mounted on the rotating columns 62; and a conveyor belt 64 driven to the conveyor wheels 63 for moving large waste on the water surface; and a driving component 65 mounted on the collection box 5 for rotating the rotating columns 62. The driving component 65 drives the rotating columns 62 and the conveyor wheels 63 to rotate, which in turn causes the conveyor belt 64 to move. The conveyor belt 64 then lifts large waste such as plastic bottles that have moved to this location upwards and ultimately into the collection box 5.

[0053] In this embodiment, preferably, please refer to [reference needed]. Figure 1-4 The driving component 65 includes: a fixed plate 651, disposed on the collection box 5, with a second rotating rod 652 rotatably mounted on the fixed plate 651 via bearings, and a worm gear 653 mounted on the second rotating rod 652; a worm 654, disposed at one end of the rotating column 62 and meshing with the worm gear 653; a driving component 656 on the collection box 5, which is drively connected to the other end of the rotating column 62 (in this application, the driving component 656 is a servo motor); and a linkage component 655, connecting the second rotating rod 652 and the first rotating rod 44, so that when the second rotating rod 652 rotates, it simultaneously drives the first rotating rod 44 to rotate. The driving component 656 drives the rotating column 62 to rotate, which in turn drives the worm gear 654 to rotate, which in turn drives the worm gear 653 and the second rotating rod 652 to rotate. The second rotating rod 652, through the linkage component 655, simultaneously drives the first rotating rod 44 to rotate.

[0054] In this embodiment, preferably, please refer to [reference needed]. Figure 1-4The linkage component 655 includes a first pulley 6551 mounted on the first rotating rod 44 and a second pulley 6552 mounted on the second rotating rod 652. A transmission belt 6553 drives the first pulley 6551 and the second pulley 6552 to rotate. When the second rotating rod 652 rotates, it drives the second pulley 6552 to rotate. Through the transmission belt 6553, the first pulley 6551 and the first rotating rod 44 can be rotated simultaneously.

[0055] In this embodiment, preferably, please refer to [reference needed]. Figure 1 and Figure 7-8 A base plate 8 is evenly distributed on the conveyor belt 64, and a baffle 9 is movably inserted into the base plate 8. A limiting component 10 for fixing the baffle 9 is provided on the base plate 8. Multiple water-filtering holes 11 are formed through the conveyor belt 64. The baffle 9 supports and blocks large waste such as plastic bottles on the conveyor belt 64, allowing the waste to be smoothly carried by the conveyor belt 64 to the collection box 5. The baffle 9 can be adjusted and replaced as needed; to replace it, the baffle 9 is inserted into the base plate 8 and then fixed by the limiting component 10. Water carried by the conveyor belt 64 is filtered out through the water-filtering holes 11.

[0056] In this embodiment, preferably, please refer to [reference needed]. Figure 7-9 The baffle 9 has a limiting hole 12. The limiting component 10 includes a limiting rod 101 that movably passes through the side wall of the base plate 8 and is adapted to the limiting hole 12. A pull block 102 is provided at the outer end of the limiting rod 101. An elastic element 103 is provided between the pull block 102 and the base plate 8. In this application, the elastic element 103 is a spring. When the baffle 9 is inserted into the base plate 8, the baffle 9 will squeeze the limiting rod 101, causing the limiting rod 101 to move outward from the base plate 8 and stretching the elastic element 103. When the baffle 9 is fully inserted into the base plate 8, the limiting hole 12 is in the position of the limiting rod 101. The limiting rod 101 is no longer squeezed and is driven to rebound by the rebound force of the elastic element 103. The limiting rod 101 will then enter the limiting hole 12, thereby fixing the baffle 9. When it is necessary to remove the baffle 9, pull the pull block 102 outward, which will move the limiting rod 101. After the limiting rod 101 disengages from the limiting hole 12, the baffle 9 is released from its fixed state. At this time, the baffle 9 can be pulled out of the base plate 8 and replaced.
