Description

Technical Field

[0001] This invention relates to the field of river cleaning technology, and in particular to a river impurity interception and cleaning device. Background Technology

[0002] The core purpose of a river impurity interception and cleaning device is to effectively intercept and clean impurities in rivers through physical, mechanical, or hydrodynamic methods. A set of floating or fixed interception nets, fences, deflectors, etc., collects floating impurities such as garbage, oil, and algae on one side of the device. Once collected, the device uses rotating brushes, spiral conveyors, automatic scrapers, etc., to transport the impurities to a designated collection area. Finally, after processing the impurities, the device can be periodically cleaned, and the waste is transported to the riverbank via a conveyor system.

[0003] In existing technologies, traditional river impurity interception and cleaning devices generally use interception nets for interception and collection. However, conventional interception nets are prone to clogging, which can lead to excessive stress and breakage. In addition, the interception nets easily accumulate garbage and are difficult to clean. Therefore, we propose a river impurity interception and cleaning device to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide a river impurity interception and cleaning device to solve the problems mentioned in the background art. Traditional river impurity interception and cleaning devices generally use interception nets for interception and collection. However, conventional interception nets are prone to clogging, which can lead to excessive stress and breakage. In addition, the interception nets are prone to accumulating garbage and are difficult to clean.

[0005] To achieve the above objectives, this application provides the following technical solution: a river impurity interception and cleaning device, comprising two support piers and two brackets, the interception and cleaning device further comprising: A crossbeam, the front and rear ends of which are fixedly installed on the tops of two support piers; A flow guiding component is disposed at the bottom of the crossbeam and is used to guide and transport garbage on the river surface. A horizontal plate, the top of which is fixedly installed at one end of two supports, a positioning ring is fixedly installed at the bottom of the horizontal plate, and the same first interception net is fixedly installed between the rear support block and the positioning ring. The second interception net has its left end fixedly installed on the positioning ring, and its right end is fixedly connected to a tail pocket, which in turn is fixedly connected to a pipe. The tail pocket is made of stainless steel mesh. A tensioning assembly is disposed at the bottom of the horizontal plate and cooperates with the second intercepting net; The cleaning assembly includes a second motor, a second screw, a second movable plate, and an annular brush. A second mounting groove is provided at the bottom of the horizontal plate. The second motor is fixedly mounted on the right inner wall of the second mounting groove. The right end of the second screw is fixedly mounted on the output shaft of the second motor. The left end of the second screw is rotatably connected to the left inner wall of the second mounting groove. The top end of the second movable plate is slidably connected to the inside of the second mounting groove and threaded onto the second screw. The top end of the annular brush is fixedly connected to the bottom end of the second movable plate, and the annular brush is sleeved on the second interception net. A stable support frame, constructed from crossbeams and two support piers, provides a solid foundation for the entire system. The flow guiding component actively directs river debris towards the collection area, changing the traditional passive approach of the first interceptor net and effectively improving collection efficiency. The cooperation between the crossbeams and the brackets provides independent installation platforms for the first, second, and tail baskets, clearly defining the interception and collection zones and reducing mutual interference. The positioning ring ensures a stable connection between the inlets of the first and second interceptors, allowing intercepted debris to be smoothly guided into the second interceptor net for collection. The connection between the tail basket and the pipeline facilitates the centralized transport of collected impurities to designated treatment points. The tensioning component allows for adjustment of the second interceptor net's tension to accommodate varying water flow rates and debris loads. This prevents the second interceptor net from becoming too loose, affecting collection efficiency, or too tight, causing damage. The cleaning component is specifically designed for the second interceptor net and tail basket. A second motor drives a second screw, which in turn moves a second moving plate and annular brush in reciprocating motion. This automatically scrapes away impurities adhering to the inner wall of the second interceptor net and the tail basket, solving the problem of debris easily adhering to the first interceptor net and being difficult to clean. This prevents the mesh from clogging, thus avoiding the risk of the first interceptor net breaking due to excessive stress caused by clogging. The entire device achieves seamless operation from guiding, intercepting, collecting to automatic cleaning, reducing the frequency and difficulty of manual maintenance.

[0006] In a preferred embodiment, the flow guiding assembly includes a first motor, a rotating shaft, multiple first bevel gears, multiple second bevel gears, multiple connecting shafts, and multiple floating discs. A cavity is formed inside the crossbeam. The first motor is fixedly mounted on one inner wall of the cavity. One end of the rotating shaft is fixedly mounted on the output shaft of the first motor, and the other end of the rotating shaft is rotatably connected to one inner wall of the cavity. Multiple first bevel gears are fixedly sleeved on the rotating shaft. The top ends of multiple connecting shafts penetrate the bottom of the crossbeam and extend into the cavity. Second bevel gears are fixedly mounted on the top ends of corresponding connecting shafts, and the second bevel gears mesh with their corresponding first bevel gears. Floating discs are mounted on the bottom of corresponding connecting shafts. The first motor drives the rotating shaft and multiple... The first bevel gear rotates synchronously, driving the second bevel gear and the connecting shaft to rotate. This, in turn, drives the floating disc mounted at the bottom of the connecting shaft to rotate. The rotating floating disc uses its outer teeth to agitate the water flow, creating a directional water flow on the river surface. This actively guides floating debris towards the first interception net. This active flow guidance method greatly reduces the pressure on the first interception net from passively bearing the impact of debris, reducing the risk of blockage at the source. Multiple floating discs are distributed along the length of the crossbeam, effectively covering a wider river section and ensuring effective debris collection. The drive components, such as the first motor and transmission gear set, are integrated into the cavity of the crossbeam, resulting in a compact structure that avoids direct water erosion, improving the durability and reliability of the device.

[0007] In a preferred embodiment, rectangular sleeves are fixedly installed at the bottom ends of multiple connecting shafts. Rectangular rods are slidably fitted inside the rectangular sleeves. The top of the float is fixedly installed at the bottom end of the corresponding rectangular rod. The bottom end of the connecting shaft is connected to the float via a sliding connection between the rectangular sleeve and the rectangular rod. This design allows the installation height of the float to be flexibly adjusted, and the rectangular rod can slide up and down within the rectangular sleeve, thereby adapting to changes in river water level caused by different seasons or sluice gate regulation. This ensures that the float can always float at the effective working depth on the river surface, maintaining a stable flow guiding effect. The rectangular cross-section effectively prevents the float from rotating relative to the connecting shaft during rotation, ensuring the reliability of power transmission and the stability of the float's rotation direction. The structure is simple and easy to adjust, enhancing the device's adaptability to different hydrological conditions.

[0008] In a preferred embodiment, the tensioning assembly includes a vertical rod, a first movable plate, a first screw, a worm gear, a worm, and a drive shaft. The bottom end of the vertical rod is fixedly connected to the right end of the tail basket. The bottom end of the first movable plate is fixedly installed on the top of the vertical rod. A first mounting groove is formed at the bottom of the horizontal plate. The top end of the first movable plate is slidably connected to the inside of the first mounting groove. The first screw is rotatably connected to the inner wall of the first mounting groove. The first movable plate is threaded onto the first screw. The worm gear is fixedly mounted on the first screw, and the worm meshes with the worm gear. The top end of the drive shaft is rotatably connected to the top inner wall of the first mounting groove. The worm is fixedly mounted on the drive shaft. The drive shaft drives the worm to rotate, which in turn drives the meshing worm gear to rotate. The worm gear then drives the first screw to rotate. Because the first movable plate is slidably connected to the first mounting groove and threaded onto the first screw, the rotation of the first screw is converted into linear motion of the first movable plate, thereby driving the vertical rod fixed to the bottom of the first movable plate to move axially along the second interception net, realizing the tensioning or loosening adjustment of the second interception net. This adjustment mechanism allows the operator to adjust the tension of the second interception net in a timely manner according to the amount of garbage in the river and the magnitude of the water flow impact. When the amount of garbage is large, it can be moderately tightened to maintain a good collection shape, and when the water flow is rapid, it can be appropriately loosened to buffer the impact force and protect the structure of the second interception net. The worm gear mechanism has a self-locking characteristic and can automatically lock the position after adjustment to prevent the second interception net from loosening on its own under the impact of the water flow, ensuring the stability of the working state.

[0009] As a preferred embodiment, a fixing rod is fixedly installed at the bottom of the second intercepting net. One end of the fixing rod is fixedly installed at the right end of the tail pocket. The fixing rod directly and fixedly connects the bottom of the second intercepting net to the right end of the tail pocket. This design makes the second intercepting net and the tail pocket more stable.

[0010] In a preferred embodiment, a bearing is fixedly mounted on the drive shaft. The bearing is fixedly installed on the right inner wall of the first mounting groove and supports the drive shaft, providing stable and reliable rotational support for the drive shaft. This effectively reduces the radial runout and axial movement of the drive shaft during transmission, ensuring the smoothness and accuracy of the worm gear meshing transmission, reducing the risk of wear or jamming caused by transmission problems. The installation of the bearing makes the rotation of the drive shaft more effortless, reducing the torque required for driving, and also plays a role in sharing the load, protecting the drive shaft and worm gear, and extending the service life of the core transmission components of the tensioning assembly.

[0011] In a preferred embodiment, a sliding ring is fixedly installed at the bottom of the annular brush, and a sliding shaft is fixedly installed on the positioning ring. The sliding ring is slidably sleeved on the sliding shaft. The sliding ring is fixed to the bottom of the annular brush and slidably sleeved on the sliding shaft between the positioning ring and the vertical rod. This provides stable bottom guidance and auxiliary support for the reciprocating motion of the annular brush when cleaning the second intercepting net and the tail basket. As a fixed guide rail, the sliding shaft can limit the swinging or deflection of the annular brush during movement, ensuring that the annular brush always maintains good contact and alignment with the outer wall of the second intercepting net, making the cleaning action more uniform and effective. The sliding cooperation between the sliding ring and the sliding shaft shares part of the lateral force borne by the second moving plate, improving the structural rigidity and stability of the entire cleaning assembly during operation, making the cleaning movement of the annular brush more stable and smooth.

[0012] As a preferred embodiment, the floating plate is made of foam board, and multiple teeth are fixedly installed at equal intervals in a ring on the outer side of the floating plate. The use of foam board gives the floating plate excellent buoyancy, enabling it to float stably on the water surface and adapt to slight fluctuations in water level, ensuring the continuous effectiveness of the flow guiding function. The multiple teeth at equal intervals in a ring on the outer side of the floating plate can effectively agitate and move the surface water flow when the floating plate rotates, enhancing the ability to guide and push floating impurities on the water surface and improving the flow guiding efficiency. The foam material is lightweight and has a certain degree of elasticity, which can deform and buffer when encountering large or hard objects floating in the water, reducing collision damage and extending the service life of the floating plate. At the same time, its material is relatively easy to obtain and process, which helps to control the cost of the device.

[0013] The beneficial effects of this invention are: 1. The second motor drives the second screw to move the second moving plate and the ring brush back and forth, which can automatically scrape off the impurities adhering to the inner wall and tail pocket of the second interception net. This solves the problem that the first interception net is easy to stick to and difficult to clean, prevents the mesh from clogging, and avoids the risk of the first interception net breaking due to excessive force caused by clogging. The whole device realizes a continuous operation from guiding, intercepting, collecting to automatic cleaning, reducing the frequency and difficulty of manual maintenance. 2. The first motor drives the rotating shaft and multiple first bevel gears to rotate synchronously. The first bevel gear drives the second bevel gear and the connecting shaft to rotate, thereby driving the floating plate installed at the bottom of the connecting shaft to rotate. The rotating floating plate uses its outer teeth to move the water flow, generating a directional water flow guidance effect on the river surface. It can actively transport floating garbage towards the first interception net. This active flow guidance method greatly reduces the pressure on the first interception net that is passively subjected to garbage impact, reducing the risk of blockage from the source. Multiple floating plates are distributed along the length of the crossbeam, which can effectively cover a wider river section and ensure the garbage collection effect. The drive components such as the first motor and the transmission gear set are integrated into the cavity of the crossbeam, which has a compact structure and can avoid direct water erosion, improving the durability and reliability of the device. 3. The drive shaft drives the worm to rotate, which in turn drives the worm wheel to rotate. The worm wheel then drives the first screw to rotate. Since the first moving plate is slidably connected to the first mounting groove and threaded onto the first screw, the rotation of the first screw is converted into linear motion of the first moving plate. This causes the vertical rod fixed to the bottom of the first moving plate to move axially along the second interception net, thus achieving the tensioning or loosening adjustment of the second interception net. This adjustment mechanism allows the operator to adjust the tension of the second interception net in a timely manner according to the amount of garbage in the river and the magnitude of the water flow impact. When the amount of garbage is large, it can be moderately tightened to maintain a good collection shape. When the water flow is rapid, it can also be appropriately loosened to buffer the impact force and protect the structure of the second interception net. The worm gear mechanism has a self-locking characteristic and can automatically lock the position after adjustment to prevent the second interception net from loosening itself under the impact of the water flow, ensuring the stability of the working state. This invention actively guides garbage to gather via a floating platform, avoiding the problem of easy clogging and breakage of the first interception net; it uses a tensioning component to adjust the tension of the second interception net to adapt to different water flows and garbage volumes; the cleaning component automatically scrapes away impurities from the second interception net and the tail basket to prevent mesh blockage; and the floating platform can adjust its height according to the water level, with a self-locking worm gear mechanism, effectively reducing maintenance frequency and improving interception and cleaning effects.

[0016] The present invention will be further explained below with reference to specific embodiments.

[0017] Example 1 refer to Figures 1-5 This embodiment proposes a river impurity interception and cleaning device, comprising two support piers 1 and two brackets 13 forming a basic frame. The bottom ends of the two support piers 1 are fixedly installed on both sides of the riverbank, and the bottom ends of the two brackets 13 are both L-shaped and fixedly installed on the riverbank. The front and rear ends of the crossbeam 2 are fixedly installed on the tops of the two support piers 1, forming a stable support structure. The flow guiding component is set at the bottom of the crossbeam 2, specifically including: a cavity 3 is opened inside the crossbeam 2, a first motor 4 is fixedly installed on the inner wall of one side of the cavity 3, one end of the rotating shaft 5 is connected to the output shaft of the first motor 4, and the other end is rotatably connected to the inner wall of the other side of the cavity 3. Multiple first bevel gears 6 are uniformly fixedly sleeved along the length of the rotating shaft 5, and a connecting shaft 8 is set below each first bevel gear 6. The top end of the connecting shaft 8 passes through the bottom of the crossbeam 2 and enters the cavity 3 to fix and install a second bevel gear 7, so that the second bevel gear 7 meshes with the first bevel gear 6 for transmission. A rectangular sleeve 9 is fixedly installed at the bottom of the connecting shaft 8. A rectangular rod 10 is slidably fitted inside the rectangular sleeve 9. The float 11 is made of foam board, and its top is fixedly installed at the bottom of the rectangular rod 10. Multiple teeth are evenly spaced in a ring on the outer side of the float 11. When the first motor 4 starts, the drive shaft 5 drives multiple first bevel gears 6 to rotate synchronously. Through gear meshing, the second bevel gear 7 drives the connecting shaft 8 to rotate, ultimately realizing the rotation of the float 11. The teeth propel the water flow to produce a directional guiding effect.

[0018] The top two ends of the horizontal plate 14 are fixedly installed on the lower ends of two brackets 13, and the bottom is fixedly installed with a positioning ring 15. A first intercepting net 12 is fixedly installed between the rear support block 1 and the positioning ring 15. The left end of the second intercepting net 16 is fixedly connected to the positioning ring 15, and the right end of the second intercepting net 16 is fixedly connected to a tail pocket 34. The right end of the tail pocket 34 is fixedly connected to a pipe 17. The tail pocket 34 is made of stainless steel mesh. The tensioning assembly is set at the bottom of the horizontal plate 14, specifically including: the bottom end of the vertical rod 18 is fixedly connected to the right end of the tail pocket 34, and the bottom of the second intercepting net 16 is connected to the right end of the tail pocket 34 through a fixing rod 19. A first mounting groove 20 is opened at the bottom of the horizontal plate 14. The top end of the first moving plate 21 is slidably installed in the first mounting groove 20, and the bottom end is connected to the top of the vertical rod 18. A first screw 22 is rotatably installed on the inner wall of the first mounting groove 20, and the first moving plate 21 is threaded onto the first screw 22. The worm gear 23 is fixedly sleeved on the first screw 22 and meshes with the worm 24 for transmission. The worm 24 is fixedly sleeved on the drive shaft 25. The top end of the drive shaft 25 is rotatably mounted on the inner wall of the top of the first mounting groove 20 via a bearing 26. The bearing 26 is also fixedly mounted on the inner wall of the right side of the first mounting groove 20. By rotating the drive shaft 25, the worm 24 is driven to rotate, which in turn drives the first screw 22 to rotate via the worm gear 23. This drives the first moving plate 21 to move linearly along the first mounting groove 20, thereby adjusting the position of the vertical rod 18 to achieve the tension adjustment of the second intercepting net 16.

[0019] The cleaning assembly is located at the bottom of the horizontal plate 14, specifically including: a second mounting groove 27 is opened at the bottom of the horizontal plate 14, and a second motor 28 is fixedly installed on the inner wall of the right side of the second mounting groove 27. The right end of the second screw 29 is connected to the output shaft of the second motor 28, and the left end is rotatably connected to the inner wall of the left side of the second mounting groove 27. The top end of the second moving plate 30 is slidably installed in the second mounting groove 27, and threaded onto the second screw 29, while the bottom end is fixedly connected to an annular brush 31. A slip ring 32 is fixedly installed at the bottom of the annular brush 31, and a sliding shaft 33 is fixedly installed on the positioning ring 15, with the slip ring 32 slidably fitted onto the sliding shaft 33. When the second motor 28 starts, it drives the second screw 29 to rotate, causing the second moving plate 30 to reciprocate along the second mounting groove 27, so that the annular brush 31 performs a linear cleaning motion on the surface of the second interceptor net 16 and the tail pocket 34. The cooperation between the slip ring 32 and the sliding shaft 33 ensures that the annular brush 31 maintains a stable movement trajectory during the cleaning process.

[0020] Example 2 refer to Figure 3 In this embodiment, the tail cap 34 is made of dense fabric. This application scenario is mainly for river environments with relatively gentle water flow and high requirements for preventing secondary pollution that may occur when the interception net collects impurities.

[0021] The tail sack 34, made of dense fabric, offers numerous advantages. Firstly, its soft texture allows it to better conform to the shape of the second interception net 16, resulting in more thorough collection of impurities and reduced leakage. Secondly, the dense fabric possesses excellent flexibility and tensile strength, making it resistant to damage under water flow impact and effectively extending its service life. Furthermore, compared to stainless steel mesh, the dense fabric avoids secondary pollution of water quality due to rust, ensuring the stability of the river's ecological environment. Moreover, the dense fabric is less expensive, reducing the overall manufacturing and maintenance costs of the device, making it more economical and environmentally friendly while maintaining effective interception and cleaning.

[0022] Working Principle: In use, the first motor 4 and the second motor 28 are first connected to an external power source. When the river impurity interception and cleaning device is working, the first motor 4 is started first. The first motor 4 drives the rotating shaft 5, which in turn drives multiple first bevel gears 6 to rotate synchronously. The first bevel gears 6 mesh with the second bevel gears 7, causing the second bevel gears 7 to drive the connecting shaft 8 to rotate, thereby rotating the float 11. The float 11 uses its outer teeth to agitate the water flow, actively guiding the river surface garbage towards the first interception net 12. After being intercepted by the first interception net 12, the garbage flows downstream into the second interception net 16 and the tail hopper 34. Based on the water flow speed and the amount of garbage, the rotating drive shaft 25 drives the worm gear 24 to rotate, which, through the worm wheel 23, causes the first screw 22 to rotate. This drives the first moving plate 21 to move linearly along the first mounting groove 20, adjusting the position of the vertical rod 18 to adjust the tension of the second interception net 16. When garbage accumulates, the net is moderately tensioned to maintain its collection shape; when the water flow is rapid, the net is appropriately relaxed to prevent damage. Next, the second motor 28 is started. The second motor 28 drives the second screw 29 to rotate, causing the second moving plate 30 to move back and forth along the second mounting groove 27, so that the annular brush 31 makes a linear cleaning motion on the surface of the second interception net 16 and the tail pocket 34. The slip ring 32 and the slip shaft 33 cooperate to ensure the stable movement of the annular brush 31, scraping off the impurities adhering to its surface and preventing the mesh from clogging. The collected impurities are finally transported to the designated processing point through the pipe 17. It should be noted that the specific model of the first motor 4 and the second motor 28 used can be selected by those skilled in the art. Moreover, the above-mentioned first motor 4 and second motor 28 are all existing technologies, and this solution will not elaborate on them.
