[0001] This invention belongs to the field of water supply and drainage technology, and in particular relates to an intelligent ditch cleaning machine for cleaning drainage ditches. Background Technology

[0002] Drainage ditches are often installed on the inner side of mountain roads for road drainage. Long-term rainfall can cause the drainage ditches to be blocked by branches and silt. At the same time, when the silt in the drainage ditches dries up, the silt and branches will harden on the inner wall of the drainage ditches, causing the drainage cross-section of the drainage ditches to shrink, making them more prone to blockage.

[0003] Currently, the cleaning of drainage ditches relies on manual labor, which is inconvenient, requires a large amount of labor, has low efficiency, and is difficult to carry out in a timely manner due to high labor costs. This poses a safety hazard to driving on mountain roads and also shortens the service life of roads. Therefore, there is an urgent need for an intelligent ditch cleaning machine to solve this problem. Summary of the Invention

[0017] 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.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 7 This invention discloses an intelligent ditch cleaning machine for cleaning drainage ditches, comprising: an intelligent cruise vehicle body 1, a movable part at the bottom of the intelligent cruise vehicle body 1, a roller brush 4 and two wall-adhering scraping devices 18 at the front end of the intelligent cruise vehicle body 1 in the direction of travel, the two wall-adhering scraping devices 18 being respectively arranged on both sides of the intelligent cruise vehicle body 1, the wall-adhering scraping devices 18 being used to adhere to the side wall of the drainage ditch and scrape off the mud, the two ends of the roller brush 4 being rotatably connected to the movable end of the first telescopic rod 5, the fixed end of the first telescopic rod 5 being fixed to the bottom of the intelligent cruise vehicle body 1, a dust collection device being provided inside the intelligent cruise vehicle body 1, the air inlet of the dust collection device being located on the side of the roller brush 4 away from the direction of travel of the intelligent cruise vehicle body 1, one of the air outlets of the dust collection device being connected to the outside through an active air valve assembly, and the other air outlet of the dust collection device being connected to the two wall-adhering scraping devices 18 through a three-way valve 13.

[0020] In use, the intelligent cruise vehicle 1 is placed in the drainage ditch, so that the two wall-mounted scraping devices 18 contact the side wall of the drainage ditch. The intelligent cruise vehicle 1 is moved along the drainage ditch by the moving part. The two wall-mounted scraping devices 18 scrape off the solidified material on the inner wall of the drainage ditch, and the roller brush 4 moves the solidified material towards the air intake end of the dust collection device. The contact degree between the roller brush 4 and the bottom of the ditch can be adjusted by extending and retracting the first telescopic rod 5. The dust collection device collects the solidified material. This invention eliminates the need for manual cleaning of the solidified material on the side wall of the ditch, greatly saving labor and improving the cleaning efficiency of the drainage ditch.

[0021] The moving part includes two rotatable rollers 3 located in the middle of the intelligent cruise vehicle body 1, and a swivel wheel 2 located at the rear end of the intelligent cruise vehicle body 1 in the direction of travel. The two rollers 3 are symmetrically arranged, and the connecting line between the swivel wheel 2 and the two rollers 3 forms a triangle. The swivel wheel 2 can actively rotate to drive the intelligent cruise vehicle body 1 to move and steer. The swivel wheel 2 is preferably an LDL250 type swivel wheel. The intelligent cruise vehicle body 1 can realize the function of automatically tracking and moving along the extension direction of the drainage ditch. This achieves automation and intelligence, reducing manpower consumption.

[0022] Further optimization of the scheme: the wall-mounted scraping device 18 includes two symmetrically arranged rotating seats 188. The rotating seats 188 are fixed to the side wall of the intelligent cruise vehicle body 1. The two ends of the rotating rod 187 are rotatably connected between the two rotating seats 188. A drive unit is connected to either end of the rotating rod 187. Two fixed ends of third telescopic rods 182 are symmetrically fixed to the rotating rod 187, and the movable ends of the two third telescopic rods 182 are respectively hinged to the two ends of the main scraper 181. The main scraper 181 has a sliding groove 184 that extends along the length of the main scraper 181, and the two ends of the sliding groove 184 are respectively slidably connected to the auxiliary scraper assembly 183. A three-way partition 186 is fixedly connected to the middle of the sliding channel 184. The three-way partition 186 divides the sliding channel 184 into two air chambers. The air inlet end of the three-way partition 186 is connected to one of the air outlet ends of the three-way valve 13 through a hose 17. The air outlet end of the three-way partition 186 is connected to the corresponding air chamber. The air chamber is connected to the corresponding secondary scraper assembly 183. The air chamber is provided with an elastic part, one end of which is fixedly connected to one side of the three-way partition 186, and the other end of which is fixedly connected to one end of the corresponding secondary scraper assembly 183.

[0023] Because drainage ditches have various cross-sectional shapes, typically rectangular or inverted trapezoidal, and their specifications also differ, to ensure the applicability of this device, the drive unit can drive the rotating rod 187 to rotate, thereby changing the angle between the main scraper 181 and the ditch sidewall. Simultaneously, by adjusting the length of the corresponding third telescopic rod 182, the lengths of the two hinged third telescopic rods 182 on the same main scraper 181 are different, allowing the main scraper 181 to fit against the ditch sidewall. At the same time, the auxiliary scraper assembly 183 extends from the sliding groove 184 of the main scraper 181, which can expand the effective range of the main scraper 181, thereby improving the applicability of this device.

[0024] In a further optimized design, the secondary scraper assembly 183 includes a sliding blade holder 1831, which is slidably disposed within a sliding groove 184. A plurality of movable blade heads 1832 are drivenly connected to the bottom of the sliding blade holder 1831. The plurality of movable blade heads 1832 are arranged sequentially along the length of the sliding blade holder 1831 and housed within the sliding groove 184. After the movable blade heads 1832 extend out of the sliding groove 184, the tips of the movable blade heads 1832 are aligned with the tip of the main scraper 181.

[0025] To ensure effective scraping, after the movable blade 1832 extends out of the sliding groove 184, the tip of the movable blade 1832 is aligned with the tip of the main scraper 181.

[0026] The design is further optimized by providing a main air pipe 1834 in the middle of the sliding tool holder 1831. One end of the main air pipe 1834 is connected to the air chamber, and the other end of the main air pipe 1834 is connected to the outside through the air valve. The main air pipe 1834 is connected to the middle of several bronchial pipes 1833. The several bronchial pipes 1833 correspond one-to-one with several movable cutter heads 1832. The two air outlets of the bronchial pipes 1833 are respectively connected to movable limiting grooves 1835. The two movable limiting grooves 1835 are symmetrically arranged on the sliding cutter holder 1831. The sliding tool holder 1831 is slidably connected within two corresponding movable limit slots 1835.

[0027] In a further optimized design, the top end of a movable limiting rod 1836 slides vertically within the movable limiting groove 1835. The top end of the movable limiting rod 1836 engages with the movable limiting groove 1835 for limiting. The bottom end of the movable limiting rod 1836 is fixedly connected to one end of the corresponding movable cutter head 1832. A second spring 1837 is sleeved on the movable limiting rod 1836. One end of the second spring 1837 is fixedly connected to the top end of the movable limiting rod 1836, and the bottom end of the second spring 1837 is fixedly connected to the bottom inner wall of the movable limiting groove 1835.

[0028] The design is further optimized so that the valve section includes a second sealing block 1839, which is sealed at the outlet of the main air pipe 1834. The second sealing block 1839 is slidably mounted on the sliding tool holder 1831 by a number of sliding rods 18310 that are fixed at equal intervals around the circumference. The sliding tool holder 1831 has a number of sliding grooves 18311 for sliding of the sliding rods 18310. One end of the third spring 1838 is fixedly connected to one side of the second sealing block 1839, and the other end of the third spring 1838 is fixedly connected to the inner wall of the air outlet end of the main air pipe 1834.

[0029] The optimized solution includes a first spring 185, one end of which is fixedly connected to one end of the sliding tool holder 1831, and the other end of which is fixedly connected to one end of the three-way partition 186. The first spring 185 is coaxially disposed in the sliding through groove 184.

[0030] In a further optimized design, the drive unit includes a servo motor 189, the output shaft of which is axially connected to either end of the rotating rod 187, and the fixed end of the servo motor 189 is fixedly connected to the corresponding rotating seat 188.

[0031] Further optimizing the design, the dust collection device includes a dust collection chamber 6, which is located inside the intelligent cruise vehicle body 1. The air inlet of the dust collection chamber 6 is connected to a ground-level suction nozzle 7, and the air outlet of the dust collection chamber 6 is connected to the air inlet of a fan 10. A dust collection net 8 is fixedly connected to the side of the dust collection chamber 6 near the fan 10 via a fixing plate 9. The air outlet of the fan 10 is connected to the air inlet of a three-way pipe 11. One of the air outlets of the three-way pipe 11 is connected to the air inlet of a three-way valve 13 via a one-way valve 12, and the other air outlet of the three-way pipe 11 is connected to the air inlet of an active air valve assembly.

[0032] Further optimization of the scheme: the active air valve assembly includes a venting bracket 14, which is coaxially fixed to the inner wall of the corresponding air outlet end of the three-way pipe 11. The fixed end of the second telescopic rod 15 is axially fixed to the top of the venting bracket 14, and the movable end of the second telescopic rod 15 is axially connected to a cap 16, which is used to block the corresponding air outlet end of the three-way pipe 11.

[0033] In use, the blower 10 operates, giving the near-ground suction nozzle 7 a strong suction force to pick up the solidified material scraped off the side wall of the ditch. The solidified material enters the dust collection screen 8 through the dust collection chamber 6. Meanwhile, the airflow flows out from the outlet of the blower 10. Under the action of the three-way pipe 11, one stream of airflow enters the three-way valve 13 through the one-way valve 12, and then enters the three-way partition 186 through the hose 17. From the three-way partition 186, the airflow enters the corresponding air chamber and pushes the corresponding secondary scraper assembly 183 out of the sliding groove 184, causing the corresponding first spring 185 to stretch. Meanwhile, the air entering the air chamber enters through the air inlet of the main air pipe 1834 provided on the sliding blade holder 1831, passes through each branch pipe 1833, and enters the movable limiting groove 1835, pushing the corresponding movable limiting rod 1836 to move downward, thereby pushing the movable blade head 1832 to move, compressing the second spring 1837, and making the tip of the movable blade head 1832 and the tip of the main scraper 181 on the same straight line. At the same time, when the air pressure remains stable, it can maintain the tip of the movable blade head 1832 and the tip of the main scraper 181 on the same straight line.

[0034] Because the sidewall lengths of different ditches are different, after the sliding cutter holder 1831 slides out, its end will contact the top or bottom of the ditch, restricting the extension of the sliding cutter holder 1831. At the same time, the movable cutter head 1832 will also partially extend out of the sliding groove 184. The remaining movable cutter head 1832 cannot extend due to the limiting effect of the sliding groove 184. Therefore, a second sealing block 1839 is provided at the air outlet end of the main air pipe 1834. When the sliding cutter holder 1831 and the movable cutter head 1832 have both moved into place, the excess gas will push open the second sealing block 1839 and cause the third spring 1838 to extend. The second sealing block 1839 drives the sliding rod 18310 to slide in the sliding groove 18311 to realize exhaust.

[0035] Meanwhile, by raising and lowering the second telescopic rod 15, the distance between the cover 16 and the top of the intelligent cruise vehicle body 1 can be controlled, thereby controlling the flow rate of the airflow generated by the fan 10 from one of the outlets of the three-way pipe 11 to the outside. When the distance between the cover 16 and the top of the intelligent cruise vehicle body 1 is small, most of the gas is used by the one-way valve 12 to extend and maintain stability of the sliding blade holder 1831 and the movable blade head 1832, and the remaining gas flows out through the outlet of the three-way pipe 11 connected to the outside. With this setting, the gas flow rate of the fan 10 can be ensured without attenuation, thereby ensuring suction.

[0036] When the fan 10 stops running, the third spring 1838 returns to its original length, causing the second sealing block 1839 to block the air outlet of the main air pipe 1834. Then, the compressed second spring 1837 returns to its original length, causing the movable blade head 1832 to approach the sliding blade holder 1831, thus facilitating its entry into the sliding through groove 184. Subsequently, the first spring 185 returns to its original length, pulling the auxiliary scraper assembly 183 back into the sliding through groove 184, thus realizing the storage of the auxiliary scraper assembly 183.

[0037] Further optimization of the design: a camera and lidar module 102 are installed at the front end of the intelligent cruise vehicle body 1 in the direction of travel; a positioning module 103 is installed at the top center of the intelligent cruise vehicle body 1; a battery module 104 is embedded in the intelligent cruise vehicle body 1; the battery module 104 is electrically connected to a wireless charging module 105; and the wireless charging module 105 is fixedly connected to the rear end of the intelligent cruise vehicle body 1 in the direction of travel.

[0038] To achieve automatic cruise control of the intelligent cruise vehicle 1, a camera and LiDAR module 102 are installed at the front of the intelligent cruise vehicle 1 in the direction of travel. The camera captures actual road images, and the intelligent cruise vehicle 1 is guided to move and avoid obstacles through video analysis and LiDAR mapping scan results. The intelligent cruise vehicle 1 is located through a positioning module 103. A battery module 104 embedded in the intelligent cruise vehicle 1 provides power to the device. Wireless charging pads 19 and solar panels and battery packs 20 are installed at intervals along the road. The solar panels and battery packs 20 convert solar energy into electrical energy stored in the battery, which then powers the wireless charging pads 19. When the battery module 104 in the intelligent cruise vehicle 1 has low power, it only needs to move to the nearest wireless charging pad 19 and connect electrically with the wireless charging pad 19 through a wireless charging module 105 to charge the battery module 104. The navigation system and automatic cruise equipment used in the intelligent cruise vehicle 1 are existing technologies and will not be described in detail here.
