Description

Technical Field

[0001] The present invention belongs to the field of water conservancy drainage channels, and specifically relates to a cleaning device for water conservancy drainage channels. Background Art

[0002] Common building materials for constructing large drainage channels include bricks, stones, clay blocks, concrete blocks, reinforced concrete blocks, and reinforced concrete. Their cross-sectional forms include circular, trapezoidal, semi-elliptical, etc. A drainage channel is an artificial or natural channel, mainly used as a water conservancy project facility for collecting and discharging rainfall, groundwater, and field water. The drainage channel can effectively drain accumulated water and cement-like soil, avoiding waterlogging disasters and farmland waterlogging disasters. In addition, the drainage channel can also collect and treat urban wastewater and industrial wastewater, reducing the urban drainage pressure and improving the urban ecological environment. Due to the complex composition of the sewage in the drainage channel, after long-term use, silt will accumulate in the drainage channel, resulting in abnormal odors near the drainage channel and affecting the drainage flow of the drainage channel.

[0003] Most of the existing technologies wash the silt deposited in the drainage channel by means of high-pressure water guns. However, before that, it is necessary to drain the sewage in the drainage channel before washing, and the steps are very cumbersome. If the silt is directly cleaned without draining the sewage in the drainage channel, most of the silt will flow downward along the water flow, causing the silt to accumulate more heavily downstream, treating the symptoms rather than the root cause. In addition, when washing a drainage channel with a trapezoidal cross-sectional form, due to the inclined inner wall, when the water flow sprays out, some silt will flow upward along the drainage channel, washing the silt outside the drainage channel and affecting the nearby environment.

[0004] Therefore, the present invention provides a cleaning device for water conservancy drainage channels. Summary of the Invention

Detailed implementation manners

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0024] As Figures 1 to 11As shown in the figure, the present invention provides a technical solution, a cleaning device for a water conservancy drainage channel, including a water tank 1. A water blocking component is arranged at the bottom of the water tank 1. The outer wall of the water tank 1 is fixedly connected with a motor 7. The output end of the motor 7 extends into the interior of the water tank 1 and is fixedly connected with a lead screw 8. The lead screw 8 is rotationally connected with the water tank 1. The outer wall of the lead screw 8 is connected with a slide plate 9 through a lead screw nut pair. The slide plate 9 is slidably connected with the water tank 1. The bottom of the slide plate 9 is fixedly connected with a slurry pump 10. The output end of the slurry pump 10 is fixedly connected with a water pumping pipeline 11. Two water inlet pipelines 12 are symmetrically and fixedly connected to the outer wall of the water pumping pipeline 11. One end of each of the two water inlet pipelines 12 penetrates through the water tank 1. A telescopic pipeline 13 is fixedly connected between the two water inlet pipelines 12. The outer wall of the head end of the telescopic pipeline 13 is fixedly connected with a first fixing plate 14. The outer wall of the tail end of the telescopic pipeline 13 is fixedly connected with a second fixing plate 16. The bottom of the first fixing plate 14 is fixedly connected with an electric telescopic rod 15. The output end of the electric telescopic rod 15 is fixedly connected with the second fixing plate 16. A flushing component is arranged on one side of the first fixing plate 14. A filter screen 43 is fixedly connected to the inner wall of the water tank 1 and below the water pumping pipeline 11. The top of the filter screen 43 is set as a symmetric inclined plane.

[0025] Through the above technical solution, the water tank 1 is moved above the drainage channel. The water blocking component seals a part of the drainage channel below the water tank 1 to intercept the sewage at a certain position in the drainage channel. The electric telescopic rod 15 is started to drive the telescopic pipeline 13 to extend downward and insert into the sewage. The slurry pump 10 is started to pump the intercepted sewage in the drainage channel into the water tank 1 along the telescopic pipeline 13, the water inlet pipelines 12, and the water pumping pipeline 11. The sewage is filtered by the arranged filter screen 43, so that sundries such as silt are left above the filter screen 43, and the filtered sewage accumulates below the filter screen 43, which is convenient for flushing the silt deposited in the drainage channel and is convenient for use in places where water supply is unavailable. The filtered sewage is sprayed out through the flushing component, which is convenient for flushing down the silt deposited in the drainage channel. The motor 7 is started to drive the lead screw 8 to rotate, so that the slide plate 9 moves to one side. While the slide plate 9 moves, it drives the telescopic pipeline 13 and the flushing component to move horizontally. After the flushing is completed, the silt originally adhered to the inner wall of the drainage channel is mixed into the water and is pumped again by the slurry pump 10, which is convenient for cleaning the silt deposited in the drainage channel.

[0026] Specifically, the flushing assembly includes two fixing brackets 22. The two fixing brackets 22 are symmetrically and fixedly installed on one side of the first fixing plate 14. The outer walls of the two fixing brackets 22 are fixedly connected with mounting brackets 38. A rotating shaft 39 is rotatably connected to the inner wall of the mounting bracket 38. Two brackets 40 are symmetrically and fixedly connected to the outer wall of the rotating shaft 39. A spray head 41 is fixedly connected between the two brackets 40. Two water pumps 48 are symmetrically and fixedly connected to the bottom of the water tank 1. The output ends of the two water pumps 48 are fixedly connected with hoses 49. The input ends of the water pumps 48 extend into the interior of the water tank 1. The hose 49 is fixedly connected with the spray head 41. An adjusting assembly is arranged between the two fixing brackets 22.

[0027] Through the above technical solution, when the water pump 48 is started, the filtered sewage in the water tank 1 is pumped and conveyed along the hose 49 to the spray head 41 and sprayed out through the spray head 41, which is convenient for flushing the silt adhering to the inner wall of the drainage channel. While the slide plate 9 moves, it drives the water inlet pipe 12 to move horizontally, makes the telescopic pipe 13 move horizontally, drives the fixing bracket 22 to move horizontally, and makes the spray head 41 move horizontally. Through the arranged adjusting assembly, the spray head 41 moves horizontally and swings downward at the same time, thereby being able to increase the flushing range of the spray head 41.

[0028] Specifically, the adjusting assembly includes a rack 23. The rack 23 is arranged between the two fixing brackets 22 and is slidably connected with the two fixing brackets 22. A gear 42 is fixedly connected to the outer wall of the rotating shaft 39. The gear 42 is meshed with the rack 23. Both sides of the rack 23 are fixedly connected with side plates 33. Sliders 34 are fixedly connected to the sides of the two side plates 33 close to each other. The slider 34 is arranged in a cylindrical shape. A guide rail 26 is fixedly connected to the bottom of the water tank 1. Continuous V-shaped grooves 35 are formed on both sides of the guide rail 26. The slider 34 fits against the inner wall of the V-shaped groove 35.

[0029] Through the above technical solution, while the slide plate 9 moves horizontally, it drives the first fixing plate 14 to move horizontally, makes the rack 23 move horizontally, drives the side plates 33 and the sliders 34 to move horizontally. While the slider 34 moves horizontally, it presses against the inner wall of the V-shaped groove 35. Under the guidance of the inner wall of the V-shaped groove 35, the slider 34 reciprocally moves up and down, drives the side plates 33 to reciprocally move up and down, and makes the rack 23 reciprocally move up and down between the two fixing brackets 22. When the rack 23 moves upward, it drives the gear 42 to rotate, makes the bracket 40 swing downward, and drives the spray head 41 to swing downward. When the rack 23 moves downward, it makes the bracket 40 swing upward and drives the spray head 41 to swing upward.

[0030] Specifically, two sliding shafts 30 are symmetrically and fixedly connected to the top of the inner wall of the guide rail 26. A top plate 27 is slidably connected to the outer walls of the two sliding shafts 30. Limit blocks 32 are fixedly connected to the bottoms of the two sliding shafts 30. Second springs 31 are sleeved on the outer walls of the two sliding shafts 30. The top of the second spring 31 is fixedly connected to the guide rail 26, and the bottom of the second spring 31 is fixedly connected to the top plate 27. A first contact 28 is fixedly connected to the outer wall of the top plate 27. The first contact 28 abuts against the inner wall of the guide rail 26. A second contact 29 is fixedly connected to the inner wall of the guide rail 26 and above the top plate 27. When the first contact 28 contacts the second contact 29 to conduct electricity, the water pump 48 operates. Two groups of top blocks 37 are symmetrically and slidably connected to the inner wall of the top plate 27. The top and bottom of the top block 37 are both beveled. A third spring 36 is fixedly connected to one side of the top block 37. The third spring 36 is fixedly connected to the top plate 27. An installation plate 24 is fixedly connected to the top of the rack 23. A clamping block 25 is fixedly connected to the top of the installation plate 24. The clamping block 25 is located between the two groups of top blocks 37. The elastic force of the third spring 36 is greater than the elastic force of the second spring 31.

[0031] Through the above technical solution, when the rack 23 moves upward, it pushes the installation plate 24 to move upward, causing the clamping block 25 to move upward. Since the clamping block 25 abuts against the bevel at the bottom of the top block 37 in the initial state, when the clamping block 25 moves upward, it can push the top block 37 to drive the top plate 27 to move upward, causing the first contact 28 to move upward. After the first contact 28 moves upward, it contacts the second contact 29 and continuously abuts while moving upward. After the first contact 28 abuts against the second contact 29, it controls the water pump 48 to start, so that the nozzle 41 sprays water when swinging downward. When the clamping block 25 moves to the uppermost position, the second spring 31 is compressed to the limit. At this time, the clamping block 25 pushes the top block 37 to move into the top plate 27, compressing the third spring 36. When the top block 37 enters the top plate 27, the limit is lost, and under the action of the second spring 31, it drives the top plate 27 to move downward rapidly, causing the first contact 28 to move downward rapidly. When the first contact 28 moves downward to its original position, it separates from the second contact 29, turning off the water pump 48. When the rack 23 moves downward, it drives the clamping block 25 to move downward. By also setting the top of the top block 37 as a bevel, it is convenient for the clamping block 25 to separate from the top block 37 after moving downward. Thus, as the rack 23 reciprocates up and down, the nozzle 41 sprays water when swinging downward, facilitating flushing the silt adhering to the inner wall of the drainage channel downward, causing the silt to fall to the bottom of the drainage channel, and stopping spraying water when swinging upward, preventing the silt adhering to the inner wall of the drainage channel from flowing upward along the slope of the inner wall of the drainage channel under the impact of the water flow, and avoiding the leakage of silt to pollute the surrounding environment.

[0032] Specifically, the water blocking assembly includes two hydraulic cylinders 2. The two hydraulic cylinders 2 are symmetrically and fixedly installed inside the water tank 1. Output ends of the two hydraulic cylinders 2 are fixedly connected with baffles 3. Both sides of the baffle 3 are beveled.

[0033] Through the above technical solution, when dredging a certain section of the drainage channel, two hydraulic cylinders 2 are started to drive two baffles 3 to move downward and insert into the drainage channel. By setting both sides of the baffle 3 as inclined surfaces, it is convenient to better fit the inner wall of the drainage channel. The two baffles 3 are used to block the drainage channel under the water tank 1, preventing the silt from flowing downstream after being washed down, effectively preventing the phenomenon that the downstream is blocked more seriously by silt, and after pumping the water in the drainage channel under the water tank 1, the flushing effect of the nozzle 41 on the silt can be improved.

[0034] Specifically, a rubber ring 4 is arranged on the inner wall of the baffle 3, an air pump 5 is fixedly connected to the outer wall of the baffle 3, an air delivery pipe 6 is fixedly connected to the output end of the air pump 5, and one end of the air delivery pipe 6 penetrates through the baffle 3 and extends into the inside of the rubber ring 4.

[0035] Through the above technical solution, the air pump 5 is started to pump the outside air along the air delivery pipe 6 into the rubber ring 4, so that the rubber ring 4 expands and fits tightly with the inner wall of the drainage channel, which is convenient to improve the fitting effect of the baffle 3 on the drainage channel and has a better sealing effect on the drainage channel.

[0036] Specifically, a connecting pipe 17 is slidably connected to the inner wall of the telescopic pipe 13. A first scraping plate 18 is fixedly connected to the bottom of the connecting pipe 17. The top of the first scraping plate 18 is provided with symmetric inclined surfaces. A feeding groove 21 is formed inside the first scraping plate 18. The bottom of the connecting pipe 17 extends into the inside of the feeding groove 21. A first spring 19 is sleeved on the outer wall of the connecting pipe 17. The top of the first spring 19 is fixedly connected to the telescopic pipe 13, and the bottom of the first spring 19 is fixedly connected to the first scraping plate 18.

[0037] Through the above technical solution, when the electric telescopic rod 15 pushes the telescopic pipe 13 to extend downward for pumping water, the first scraping plate 18 is driven to move downward. Under the action of the first spring 19, the first scraping plate 18 fits the bottom of the drainage channel. As the telescopic pipe 13 is controlled to move horizontally, the first scraping plate 18 is driven to move horizontally, which is convenient to scrape the silt at the bottom of the drainage channel, preventing the silt from adhering to the bottom of the drainage channel and being unable to be pumped. Moreover, the silt washed down from the inner wall of the drainage channel can flow along the inclined surface at the top of the first scraping plate 18, so that the silt can be concentrated at the feeding groove 21, which is convenient to pump.

[0038] Specifically, guide plates 20 are fixedly connected to both sides of the first scraping plate 18, and the outer walls of the guide plates 20 are provided with symmetric inclined surfaces.

[0039] Through the above technical solution, when the first scraping plate 18 moves horizontally, the guide plates 20 are driven to move horizontally. Under the guidance of the inclined surfaces on the outer walls of the guide plates 20, the silt scraped by the first scraping plate 18 can flow along the inclined surfaces on the outer walls of the guide plates 20, so that the silt can be concentrated at the feeding groove 21, which is convenient to pump.

[0040] Specifically, two connecting frames 44 are symmetrically and fixedly connected to the outer wall of the pumping pipeline 11. The bottom of the two connecting frames 44 is fixedly connected with a second scraper 45, and the second scraper 45 is attached to the top of the filter screen 43.

[0041] Through the above technical solution, while the pumping pipeline 11 moves horizontally, it can drive the two connecting frames 44 to move horizontally, so that the second scraper 45 moves horizontally. By the attachment of the second scraper 45 to the filter screen 43, while the second scraper 45 moves horizontally, the surface of the filter screen 43 can be cleaned, preventing the filter screen 43 from being blocked by silt and affecting the pumping of the water pump 48 below.

[0042] Specifically, two discharge ports 46 are symmetrically formed in the outer wall of the water tank 1 and above the filter screen 43. A sealing door 47 is slidably connected to the outer wall of the water tank 1 and above the discharge port 46.

[0043] Through the above technical solution, when pumping and filtering the sewage in the drainage ditch, the sealing door 47 is moved downward to seal the discharge port 46 to prevent sewage from leaking. When the silt on the filter screen 43 accumulates too much, by moving the sealing door 47 upward, the discharge port 46 can be opened to facilitate the removal of the silt on the filter screen 43.

[0044] During use, move the water tank 1 above the drainage channel, lower the sealing door 47 to seal the discharge port 46, start the two hydraulic cylinders 2 to drive the two baffles 3 to move downward and insert them into the drainage channel. By setting both sides of the baffle 3 as inclined planes, it is convenient to better fit the inner wall of the drainage channel. The two baffles 3 are used to block the drainage channel under the water tank 1, preventing the silt from flowing downstream after being washed down, effectively preventing the downstream from being blocked more severely by silt. Moreover, after pumping the water in the drainage channel under the water tank 1, it can improve the flushing effect of the nozzle 41 on the silt. Start the air pump 5 to draw the outside air along the air delivery pipe 6 into the rubber ring 4, causing the rubber ring 4 to expand, which is convenient to improve the fitting effect of the baffle 3 on the drainage channel and achieve a better sealing effect on the drainage channel. Start the electric telescopic rod 15 to drive the telescopic pipe 13 to extend downward and insert it into the sewage. Start the slurry pump 10 to pump the sewage intercepted in the drainage channel along the telescopic pipe 13, the water inlet pipe 12, and the pumping pipe 11 into the water tank 1. The sewage is filtered by the set filter screen 43, leaving sundries such as silt above the filter screen 43, and the filtered sewage accumulates below the filter screen 43, which is convenient to flush the silt deposited in the drainage channel and is convenient to use in places where water supply is unavailable. Start the water pump 48 to pump the filtered sewage in the water tank 1 along the hose 49 to the nozzle 41 and spray it out through the nozzle 41, which is convenient to flush the silt adhering to the inner wall of the drainage channel. Start the motor 7 to drive the lead screw 8 to rotate, causing the slide plate 9 to move to one side. While the slide plate 9 moves, it drives the telescopic pipe 13 and the nozzle 41 to move horizontally, increasing the flushing range of the nozzle 41. After the flushing is completed, the silt originally adhering to the inner wall of the drainage channel is mixed into the water and is pumped again by the slurry pump 10, which is convenient to clean the silt deposited in the drainage channel. While the slide plate 9 moves horizontally, it drives the first fixing plate 14 to move horizontally, causing the rack 23 to move horizontally, driving the side plate 33 and the slider 34 to move horizontally. While the slider 34 moves horizontally, it presses against the inner wall of the V-shaped groove 35. Under the guidance of the inner wall of the V-shaped groove 35, the slider 34 reciprocates up and down, driving the side plate 33 to reciprocate up and down, causing the rack 23 to reciprocate up and down between the two fixed frames 22. When the rack 23 moves upward, it drives the gear 42 to rotate, causing the bracket 40 to swing downward, driving the nozzle 41 to swing downward. When the rack 23 moves downward, the bracket 40 swings upward, driving the nozzle 41 to swing upward. When the rack 23 moves upward, it pushes the mounting plate 24 upward, causing the block 25 to move upward. The block 25 presses against the inclined plane at the bottom of the top block 37. Under the pushing action of the block 25, the top block 37 moves upward, driving the top plate 27 upward, causing the first contact 28 to move upward. After the first contact 28 moves upward, it contacts the second contact 29 and continues to fit while moving upward. After the first contact 28 and the second contact 29 fit, it controls the water pump 48 to start, so that the nozzle 41 sprays water when it swings downward. When the block 25 moves to the uppermost position, the second spring 31 is compressed to the limit. At this time, the block 25 pushes the top block 37 into the top plate 27, compressing the third spring 36.After the top block 37 enters the top plate 27, it loses its limit. Under the action of the second spring 31, it quickly moves downward, driving the top plate 27 to quickly move downward, making the first contact 28 quickly move downward. When the first contact 28 moves downward to its original position, it separates from the second contact 29, turning off the water pump 48. When the rack 23 moves downward, it drives the latch 25 to move downward. By setting the top of the top block 37 to be beveled as well, it is convenient for the latch 25 to separate from the top block 37 after moving downward. Thus, as the rack 23 reciprocates up and down, when the nozzle 41 swings downward, water is sprayed, facilitating the downward flushing of the silt adhering to the inner wall of the drainage channel, causing the silt to fall to the bottom of the drainage channel. When it swings upward, the water spray stops, preventing the silt adhering to the inner wall of the drainage channel from flowing upward along the inclined surface of the inner wall of the drainage channel under the impact of the water flow, avoiding the leakage of silt and pollution of the surrounding environment. When the electric telescopic rod 15 pushes the telescopic pipe 13 downward to extend for pumping water, it drives the first scraper 18 to move downward. Under the action of the first spring 19, the first scraper 18 fits the bottom of the drainage channel. As the telescopic pipe 13 is controlled to move horizontally, it drives the first scraper 18 to move horizontally, facilitating the scraping of the silt at the bottom of the drainage channel, preventing the silt from adhering to the bottom of the drainage channel and being unable to be pumped. While the first scraper 18 moves horizontally, it drives the guide plate 20 to move horizontally. Through the guiding of the inclined surface on the outer wall of the guide plate 20, the silt scraped by the first scraper 18 can flow along the inclined surface of the outer wall of the guide plate 20, enabling the silt to concentrate at the feed trough 21, facilitating pumping. While the pumping pipe 11 moves horizontally, it can drive the two connecting frames 44 to move horizontally, making the second scraper 45 move horizontally. By the second scraper 45 fitting the filter screen 43, while the second scraper 45 moves horizontally, it can clean the surface of the filter screen 43, preventing the filter screen 43 from being blocked by silt, which affects the pumping of the water pump 48 below. When the silt accumulated on the filter screen 43 is too much, by moving the sealing door 47 upward, the discharge port 46 can be opened, facilitating the removal of the silt on the filter screen 43.,
