Description

Technical Field

[0001] This invention relates to the field of deep silt removal technology for lotus ponds, specifically to a deep silt removal device and method for lotus ponds. Background Technology

[0002] As part of an aquatic ecosystem, lotus ponds often accumulate a thick layer of silt at their bottom over time. This silt not only affects the pond's water storage capacity and water exchange but can also damage the habitat of aquatic organisms, such as causing eutrophication and reducing dissolved oxygen levels. Therefore, regularly cleaning the thick silt from lotus ponds is crucial for maintaining their ecological functions, aesthetic appeal, and the health of the surrounding environment.

[0003] However, existing deep silt removal equipment for lotus ponds typically uses a conveyor-like structure in the silt collection stage to guide the cleaned silt into a collection box. This often involves a sloping conveyor structure. Since silt has a certain viscosity and varying moisture content, and the sloping surface inevitably has friction, these factors easily cause silt to accumulate on the slope as it moves towards the collection box. As the cleaning operation continues, this accumulation worsens, eventually blocking the silt conveyor channel. This prevents subsequent silt from smoothly entering the collection box, affecting the overall silt removal quality and reducing cleaning efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a deep silt cleaning device and method based on lotus ponds, which solves the problem of silt accumulation during the cleaning and transportation process into the cleaning box, causing blockage of the silt conveying channel and preventing subsequent silt from smoothly entering the collection box.

[0014] A deep silt removal device and method based on lotus ponds, employing the deep silt removal device based on any one of claims 1-7, further comprising the following steps: Step 1: When the cleaning machine is cleaning the deep silt in the lotus pond, the drive motor is started to rotate the propeller, causing the cleaning machine to move on the lotus pond. When the cleaning machine moves, the cleaning blades and cleaning shaft rotate inside the cleaning machine due to the impact force of the water flow. When the cleaning blades rotate, they will move the silt through the slope to the cleaning box for collection. When the cleaning box collects the silt, the control motor can also be started to rotate the cam. When the cam rotates, it will first push the slider to slide on the top of the fixed frame through the movable rod. When the slider slides, it will drive the scraper and scraper to slide in the same direction as the slider through the connecting block. When the cam rotates, it will first push the scraper to slide downward. When the scraper slides downward, it will drive the scraper to slide downward and abut against the inclined side of the slope. When the cam rotates, it will also push the slider to slide on the top of the fixed frame through the movable rod. When the slider slides, it will drive the scraper and scraper to slide in the same direction as the slider through the connecting block, so that the scraper slides at the inclined side of the slope.

[0015] Step 2: When the scraper moves downward under the action of the cam, it will also abut against the top of the slide bar and drive the slide bar to slide downward inside the fixed block. When the slide bar slides downward, it will drive the connecting bar to slide downward. When the connecting bar slides downward, it will drive the cutter to abut against the surface of the cleaning shaft. When the cutter abuts against the surface of the cleaning shaft, it will slide on the surface of the connecting bar. After the cutter has finished sliding, it will reset under the action of the connecting spring.

[0016] Step 3: When the sludge moves through the ramp to the cleaning box for collection, it falls onto the filter plate. When the cam rotates under the control of the motor, it also drives the drive wheel to rotate. When the drive wheel rotates, it drives the second bevel gear to rotate through the belt. When the second bevel gear rotates, it drives the first bevel gear meshing at the bottom to rotate. When the first bevel gear rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the pressure plate to slide downward inside the cleaning box and abut against the top of the sludge.

[0017] (III) Beneficial Effects Compared with the prior art, the present invention provides a deep silt removal device and its usage method based on lotus ponds, which has the following beneficial effects: 1. This deep silt cleaning equipment based on lotus ponds utilizes movable components. The motor drives the rotation of a cam, which in turn pushes a slider on top of a fixed frame via a movable rod. This causes the scraper and scraper to slide similarly. When the cam rotates, it pushes the scraper and scraper downwards and against the inclined side of the slope. The cam's rotation also pushes the slider on top of the fixed frame, causing the scraper to slide at the inclined side of the slope. This effectively scrapes off the silt adhering to and accumulating on the inclined side, allowing it to continue moving into the cleaning box, keeping the silt transport channel unobstructed and improving cleaning efficiency.

[0018] 2. This deep silt cleaning equipment based on lotus ponds utilizes a cutting component. When the scraper moves downward, it also abuts against the top of the slide bar, causing the slide bar to slide downward. As the connecting bar slides downward, it causes the cutter to abut against the surface of the cleaning shaft. When the cutter abuts against the surface of the cleaning shaft, it slides on the surface of the connecting bar, which can promptly cut off the debris wrapped around it. After sliding, the connecting spring resets the equipment, making it ready to process newly appearing debris at any time. This effectively prevents the cleaning shaft from being blocked by debris and speeds up the work process.

[0019] 3. This deep silt cleaning equipment based on lotus ponds utilizes a moving component setup. When the control motor starts, it also drives the transmission wheel to rotate. The rotation of the transmission wheel drives the rotation of bevel gear two via a belt, as well as the rotation of bevel gear one meshing at the bottom. When bevel gear one rotates, it drives the rotation of the reciprocating screw. The rotation of the reciprocating screw causes the pressure plate to slide downward inside the cleaning box and press against the top of the silt to compact it, squeezing out the water in the silt, improving cleaning efficiency and facilitating the subsequent use of the silt as fertilizer.

A spiral spring 511 is fixedly installed on the surface of the rotating rod 58. The spiral spring 511 is fixedly installed on the outer wall of the connecting block 57.

A ramp 515 is fixedly installed on the left side of the cleaning box 51. The cam 54 rotates while abutting against the movable rod 56 and the slider 55, so that the scraper 510 moves on the surface of the ramp 515 when sliding down, which can scrape off the silt attached and accumulated on the slope in time.

[0024] Secondly, the cutting assembly 6 includes: a fixing block 61, which is fixedly installed inside the fixing frame 52. A slide rod 62 is slidably connected inside the fixing block 61. A movable spring 63 is fixedly installed on the surface of the slide rod 62. The movable spring 63 is fixedly installed at the bottom of the fixing block 61. A connecting strip 64 is fixedly installed at the bottom of the slide rod 62. A cutter 65 is slidably connected to the surface of the connecting strip 64. One end of a connecting spring 66 is fixedly installed inside the cutter 65. The other end of the connecting spring 66 is fixedly installed on the outer wall of the connecting strip 64. The cutter 65 can slide on the surface of the cleaning shaft 513 by the scraper 59 contacting the slide rod 62 and driving the cutter 65 to slide downward, so that the cutter 65 can slide on the surface of the cleaning shaft 513 and cut off the debris wrapped on it in time.

[0025] Furthermore, the moving component 7 includes: a fixed shaft 71, which is fixedly installed inside the cleaning machine 1. A bevel gear 72 is rotatably connected to the bottom of the fixed shaft 71. A bevel gear 73 meshes with the outer side of the bevel gear 72. The bevel gear 73 is rotatably connected to the inner wall of the cleaning machine 1. A transmission wheel 74 is fixedly installed on the surface of the output shaft of the control motor 53.

A pressure plate 76 is threadedly connected to the surface of the reciprocating screw 75. The pressure plate 76 is slidably connected inside the cleaning box 51. A filter plate 77 is slidably connected inside the cleaning box 51. The rotation of the transmission wheel 74 drives the bevel gear 73 and the bevel gear 72 meshing at the bottom to rotate via the belt. This causes the bevel gear 72 to rotate while simultaneously moving the pressure plate 76 on the surface of the reciprocating screw 75 downwards, pressing against the top of the sludge and squeezing out the water in the sludge.

[0026] Finally, a groove 520 is provided on the top of the fixing frame 52, through which the slider 55 can slide on the surface of the fixing frame 52. A groove 550 is provided on the surface of the slider 55, through which the scraper 59 can move downward without restriction. A square groove 5100 is provided on the left side of the cleaning box 51, through which the sludge can enter the interior of the cleaning box 51 for storage. A drainage groove 5101 is provided on the surface of the cleaning box 51, through which the pressure plate 76 squeezes the water inside the sludge and discharges it.

[0027] A deep silt removal device and method based on lotus ponds, employing the deep silt removal device based on any one of claims 1-7, further includes the following steps: Step 1: When the cleaning machine 1 cleans the deep silt in the lotus pond, the drive motor 2 is started to drive the propeller 3 to rotate, causing the cleaning machine 1 to move on the lotus pond. When the cleaning machine 1 moves, the cleaning blades 514 and the cleaning shaft 513 will rotate inside the cleaning machine 1 due to the impact force of the water flow. When the cleaning blades 514 rotate, they will carry the silt through the ramp 515 to the cleaning box 51 for collection. When the cleaning box 51 collects the silt, the control motor 53 can be started to drive the cam 54 to rotate. When the cam 54 rotates, it will first push the slider 55 to slide on the top of the fixed frame 52 through the movable rod 56. When the slider 55 slides, it will drive the scraper 59 and scraper 510 to slide in the same direction as the slider 55 through the connecting block 57. When the cam 54 rotates, it will first push the scraper 59 to slide downward. When the scraper 59 slides downward, it will drive the scraper 510 to slide in the same direction as the slider 55. The cam 54 slides downwards and abuts against the inclined side of the ramp 515. When the cam 54 rotates, it also pushes the slider 55 to slide on the top of the fixed frame 52 through the movable rod 56. When the slider 55 slides, it drives the scraper 59 and scraper 510 to slide in the same direction as the slider 55 through the connecting block 57. This causes the scraper 510 to slide at the inclined side of the ramp 515. During the process of sludge moving from the ramp 515 to the cleaning box 51 for collection, the sludge may gradually accumulate on the inclined side of the ramp 515 due to its own stickiness, humidity and friction of the ramp 515 surface. Over time, this can easily cause blockage of the channel, affecting the smooth entry of subsequent sludge into the cleaning box 51. The scraper 510 sliding at the inclined side of the ramp 515 can scrape off the sludge attached and accumulated at the inclined side in time, allowing it to continue to move into the cleaning box 51, keeping the sludge conveying channel unobstructed and improving cleaning efficiency.

[0028] Step Two: When the scraper 59 moves downward under the action of the cam 54, it will also abut against the top of the slide bar 62, causing the slide bar 62 to slide downward inside the fixed block 61. When the slide bar 62 slides downward, it will cause the connecting bar 64 to slide downward. When the connecting bar 64 slides downward, it will cause the cutter 65 to abut against the surface of the cleaning shaft 513. When the cutter 65 abuts against the surface of the cleaning shaft 513, it will slide on the surface of the connecting bar 64. After the cutter 65 has slid, it will return to its original position under the action of the connecting spring 66. In the process of cleaning the deep silt in the lotus pond, the silt often contains various debris such as aquatic plants, branches, and plastic strips. When the cleaning shaft 513 drives the cleaning blade 514 to rotate for silt cleaning and conveying, these debris may become entangled on the cleaning shaft 513. As time goes by, more and more debris will become entangled, which will cause the cleaning shaft 513 to be obstructed from rotating, or even unable to rotate at all, thus affecting the normal operation of the entire cleaning machine 1. The cutter 65 slides against the surface of the cleaning shaft 513, which can cut off the debris wrapped around it in time. After sliding, it is reset by the connecting spring 66, so it can be ready to process the newly entangled debris again at any time, effectively preventing the cleaning shaft 513 from being blocked by debris and speeding up the work progress.

[0029] Step 3: When the silt moves through the ramp 515 to the cleaning box 51 for collection, it falls onto the filter plate 77. When the cam 54 rotates under the control of the motor 53, it also drives the transmission wheel 74 to rotate. The rotation of the transmission wheel 74 drives the rotation of the second bevel gear 73 via a belt. The rotation of the second bevel gear 73 drives the rotation of the bottom-meshing first bevel gear 72. The rotation of the first bevel gear 72 drives the rotation of the reciprocating screw 75. The rotation of the reciprocating screw 75 drives the pressure plate 76 in the cleaning box 51. The material slides downwards and presses against the top of the silt, squeezing out the water in the silt. Since the silt itself contains a lot of water, if it is not squeezed and compacted, more and more silt will accumulate in the cleaning box 51 as the cleaning operation continues. Due to the presence of water, the silt is prone to continuous expansion and may quickly fill the space of the cleaning box 51, causing the cleaning box 51 to reach its capacity limit too early. This requires frequent stops of the cleaning machine 1 to unload the silt from the cleaning box 51, thereby improving cleaning efficiency and facilitating the subsequent use of the silt as fertilizer.
