Description

Technical Field

[0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage pipe cleaning device. Background Art

[0002] There are often some deposited debris in the sewage pipe. When the deposited debris accumulates too much, the deposited debris will cause the sewage pipe to be blocked, affecting people's production and life, so people need to clean the sewage pipe frequently. Existing sewage pipe cleaning usually introduces cleaning liquid into the pipe to dissolve hair, plastic bags and other debris in the pipe to avoid blockage, but the sludge adhering to the inner wall of the pipe cannot be dissolved, and it is necessary to manually insert some long rods into the pipe to scrape off the sludge. However, in the case of a long pipe, the cleaning liquid is introduced into the pipe from the end of the pipe and flows through the entire pipe, which requires more cleaning liquid, which may cause waste; and the long pipe makes it difficult to completely scrape off the sludge on the inner wall of the pipe. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a sewage pipe cleaning device to solve the problem that long sewage pipes are difficult to clean.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A sewage pipe cleaning device comprises a cleaning vehicle, which comprises a vehicle body and wheels installed at the lower end of the vehicle body, a cavity for storing cleaning liquid is provided in the vehicle body, a liquid inlet hole connected to the cavity is provided on the vehicle body, a rotating drum is rotatably connected to the vehicle body, the rotating drum penetrates and extends into the cavity, a slide plate is slidably connected in the cavity, a connecting cylinder is fixedly connected to the slide plate, the connecting cylinder and the rotating drum are ball-threadedly connected, and a through hole connected to the connecting cylinder is provided on the slide plate; a probe is fixed to the end of the rotating drum away from the vehicle body, and a plurality of nozzles are evenly fixed along the circumferential direction on the end of the rotating drum close to the probe, and the nozzles are all connected to the inner cavity of the rotating drum; a plurality of scrapers are evenly distributed along the circumferential direction on the rotating drum.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The cleaning vehicle enters the pipeline and moves forward through the wheels, while the rotating drum rotates. The probe rotates with the rotating drum, and the probe extends out of the vehicle body, which can help detect obstacles to the vehicle body when it moves forward to a certain extent, such as debris blocked in the pipeline; the rotating drum and the connecting cylinder form a ball screw structure. When the rotating drum rotates, it drives the connecting cylinder to slide axially, and the connecting cylinder drives the slide plate to slide, so that the cleaning liquid in the cavity is sprayed out after passing through the through hole, connecting cylinder, rotating drum, and nozzle. The nozzle rotates with the rotating drum to spray the cleaning liquid to clean the debris in the forward direction of the vehicle body. At the same time, the scraper rotates with the rotating drum to scrape off the sludge adhered to the inner wall of the pipeline. In this solution, the cleaning vehicle can complete the cleaning of the pipeline while moving forward, and it can be applied to the cleaning of pipelines of different lengths.

DETAILED DESCRIPTION

[0012] The present invention is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0013] like Figure 1 As shown, a sewage pipe cleaning device includes a cleaning vehicle, which includes a vehicle body 1 and wheels 4 installed at the lower end of the vehicle body 1. A motor I for driving the wheels 4 to rotate is fixed on the vehicle body 1. Specifically, a group of wheels 4 are installed on both sides of the lower end of the vehicle body 1. The group of wheels 4 includes a wheel axle rotatably connected to the lower end of the vehicle body 1 and two wheels 4 fixed on both sides of the wheel axle. The motor I is used to drive one of the wheel axles to rotate, and the two wheel axles are driven by belts.

[0014] The vehicle body 1 is provided with a cavity for storing cleaning liquid, and a liquid inlet hole 5 communicating with the cavity is provided on one end surface of the vehicle body 1, and an air hole 18 communicating with the cavity is provided on the other end surface of the vehicle body 1. A slide plate 7 is slidably connected in the cavity, and the sliding direction of the slide plate 7 is parallel to the forward or backward direction of the wheel 4. The slide plate 7 divides the cavity into a first cavity 2 and a second cavity 3. In this embodiment, the liquid inlet hole 5 is located in the first cavity 2, and the air hole 18 is located in the second cavity 3. That is, the cleaning liquid enters the first cavity 2 through the liquid inlet hole 5 and is stored in the first cavity 2. Figure 2 As shown, the second cavity 3 is provided with an air hole 18 to maintain the balance of the internal and external air pressures of the second cavity 3. The outer wall of the vehicle body 1 is detachably connected with a screen 19 for covering the air hole 18. Specifically, the screen 19 is fixed to the outer wall of the vehicle body 1 by bolts, and the setting of the screen 19 prevents debris from entering the second cavity 3 through the air hole 18.

[0015] The vehicle body 1 is rotatably connected with a rotating drum 9, and a motor II for driving the rotating drum 9 to rotate is fixed on the vehicle body 1. Specifically, the output shaft of the motor II and the rotating drum 9 are driven by gears, which can prevent the rotating drum 9 from slipping when encountering obstacles compared with belt drive. The rotating drum 9 and the air hole 18 are located on the same side of the vehicle body 1, and the axis of the rotating drum 9 is perpendicular to the axis of the wheel axle, and the axis of the rotating drum 9 and the sliding direction of the slide plate 7 are the same. The rotating drum 9 penetrates and extends into the second cavity 3, and the side of the slide plate 7 close to the rotating drum 9 is fixedly connected with a connecting cylinder 8, and the connecting cylinder 8 and the rotating drum 9 are connected by ball screws. The slide plate 7 is provided with a through hole 6 connected to the inner cavity of the connecting cylinder 8. The end of the rotating drum 9 located outside the vehicle body 1 is sealed and fixed with a probe 12. A plurality of nozzles 13 are evenly distributed along the circumferential direction on the side of the rotating drum 9 close to the probe 12, and the nozzles 13 are all connected to the inner cavity of the rotating drum 9. The cleaning liquid in the first cavity 2 can be discharged from the vehicle body 1 through the through hole 6, the connecting cylinder 8, the rotating drum 9, and the nozzle 13 in sequence. The axis of the nozzle 13 is inclined relative to the axis of the drum 9, and an acute angle is formed between the axis of the nozzle 13 and the axis of the probe 12.

[0016] A plurality of scrapers 10 are evenly distributed on the rotating drum 9 along the circumferential direction. A wedge block 11 is fixed to one end of the scraper 10 away from the rotating drum 9 , and the tip of the wedge block 11 faces the side away from the fixing portion 21 .

[0017] When in use, the operator places the cleaning vehicle at the opening of the sewage pipe, starts the motor I, and the motor I drives the wheel 4 to rotate, so that the cleaning vehicle enters the sewage pipe. The motor II drives the rotating drum 9 to rotate, and the probe 12 rotates with the rotating drum 9. The probe 12 extends out of the vehicle body 1, which can help to detect obstacles to the vehicle body 1 when it moves forward to a certain extent, such as debris blocked in the pipeline, and the probe 12 can push the debris away. The rotating drum 9 and the connecting cylinder 8 form a ball screw structure. When the rotating drum 9 rotates, it drives the connecting cylinder 8 to slide axially, and the connecting cylinder 8 drives the slide plate 7 to slide toward the first cavity 2, so that the cleaning liquid in the first cavity 2 passes through the through hole 6, the connecting cylinder 8, the rotating drum 9, and the nozzle 13 and then sprays out. The nozzle 13 rotates with the rotating drum 9 to spray out the cleaning liquid. With the revolution of the nozzle 13, the cleaning liquid sprays out a larger range, and the debris in the forward direction of the vehicle body 1 is cleaned. At the same time, the cleaning liquid that falls on the probe 12 can also clean the debris wrapped around the probe 12. At the same time, the scraper 10 rotates with the drum 9 to scrape off the sludge adhered to the inner wall of the pipe. Through the arrangement of the wedge block 11, the tip of the wedge block 11 can more easily scrape off the sludge on the inner wall of the pipe, and the scraping effect is better. After the cleaning vehicle leaves the outlet of the pipe, water can be passed into the pipe to wash the scraped sludge.

[0018] In another embodiment of the present invention, a motor is fixed on the vehicle body 1, the motor and the drum 9 are driven by gears, and the motor and the wheel 4 are driven by bevel gears. Specifically, a driving gear and a driving bevel gear are fixed on the output shaft of the motor, and a driven gear meshing with the driving gear is fixed on the drum 9, and the transmission ratio between the driving gear and the driven gear is 1:1. The wheel 4 includes a wheel axle rotatably connected to the lower end of the vehicle body 1 and running wheels fixed on both sides of the wheel axle. At least two wheel axles can be provided, and the plurality of wheel axles are rotated by belts, and a driven bevel gear meshing with the driving bevel gear is fixed on one of the wheel axles.

[0019] The rotation of the wheel 4 and the rotation of the drum 9 are driven by the same motor, and the rotation speed of the drum 9 affects the sliding stroke of the connecting cylinder 8 (slide plate 7), that is, affects the spraying amount of the cleaning liquid. The cleaning vehicle sprays the cleaning liquid while moving in the pipeline, and the forward speed of the vehicle body 1 is related to the spraying amount of the cleaning liquid, which reduces the waste of the cleaning liquid to a certain extent.

[0020] In another embodiment of the present invention, a camera is installed on the upper end of the vehicle body 1, and a wireless Bluetooth module for connecting to a mobile terminal signal is installed in the camera. A wireless Bluetooth camera in the prior art can be directly selected, and a Bluetooth connection between the wireless Bluetooth module and the operator's mobile phone or laptop is set. When the cleaning vehicle is located in the sewage pipe, the operator can monitor the situation in the sewage pipe through the camera.

[0021] In another embodiment of the present invention, Figure 3 As shown, the scraper 10 includes a fixed portion 21 and a telescopic portion 22 sleeved on the fixed portion 21, and an elastic member is fixed between the telescopic portion 22 and the fixed portion 21. In this embodiment, the elastic member is a spring 20. The scraper 10 is telescopic and can be used for cleaning pipes with different inner diameters, thereby improving the adaptability of the cleaning vehicle.

[0022] In another embodiment of the present invention, a water pump 14 is fixed on the vehicle body 1, and the water inlet end of the water pump 14 is connected to a water inlet pipe 16, and the water inlet pipe 16 is detachably connected to the water inlet end of the water pump 14. Specifically, the water inlet end of the water pump 14 and the end of the water inlet pipe 16 are fixed with flanges 15, and the two flanges 15 are connected by bolts, and also include a reel for winding the water inlet pipe 16. The reel can be a winding device used in the prior art for winding or loosening pipelines, and an electric reel or a manual hand-cranked reel can be selected, which will not be repeated in this application. The water outlet end of the water pump 14 is connected to a plurality of water outlet pipes, and the plurality of water outlet pipes are divided into two groups, respectively referred to as a first water outlet pipe 23 and a second water outlet pipe 17. The axial direction of the first water outlet pipe 23 is perpendicular to the axial direction of the water outlet end of the water pump 14, and the first water outlet pipe 23 is only distributed on the upper side of the water outlet end of the water pump 14, that is, the water outlet end of the first water outlet pipe 23 faces the upper half of the sewage pipe, and only one second water outlet pipe 17 is provided, and the water outlet end of the second water outlet pipe 17 faces the scraper 10.

[0023] When in use, the reel remains outside the sewage pipe, and the reel is rotated by manual or electric control to release the water inlet pipe 16. The water inlet pipe 16 can be connected to a water truck or a water tank outside the pipe. The water inlet pipe 16 enters the pipe with the cleaning vehicle, and the water pump 14 pumps water out through the outlet pipe. The water in the first outlet pipe 23 is only sprayed on the upper half of the pipe. This is because the pipe is flushed by sewage during daily use, and the lower half of the pipe is most easily flushed, so that less stubborn silt is left. In addition, when the height of the cleaning vehicle is limited (when the inner diameter of the pipe is larger), when the scraper 10 rotates to the lower half of the pipe, the telescopic part 22 retracts to a greater extent, and the telescopic part 22 is also subjected to a greater restoring force from the spring 20, so the scraping force on the lower half of the pipe is greater. Therefore, the first outlet pipe 23 is provided to assist in flushing the upper half of the pipe and clean the silt on the inner wall of the pipe by water pressure. The water from the second water outlet pipe 17 is sprayed onto the scraper 10 . As long as the scraper 10 rotates to the upper side and faces the second water outlet pipe 17 , the water sprayed from the second water outlet pipe 17 cleans the sludge adhered to the scraper 10 when cleaning the sludge.

[0024] The reel is left outside the pipeline, on the one hand, to facilitate connection with the external water source. When the operator observes through the camera that there is a lot of silt or the silt is stubbornly adhered somewhere on the inner wall of the pipeline, the water inlet volume and water pressure can be appropriately increased to better clean the pipeline. On the other hand, when the cleaning vehicle fails in the pipeline and cannot move, the operator can also use the reel to wind the water inlet pipe 16 to drag the cleaning vehicle out of the pipeline.

[0025] The water inlet pipe 16 and the water pump 14 are detachably connected. On the one hand, after the cleaning vehicle leaves the outlet of the pipeline, the water inlet pipe 16 can be detached to facilitate the reeling of the water inlet pipe 16. During the reeling process, water can continue to flow into the pipeline through the water inlet pipe 16 to bring out the sludge scraped off the pipeline to a certain extent. After the reeling is completed, water can be flowed into the pipeline to flush out the sludge. On the other hand, the water inlet pipe 16 is arranged to be relatively long. Through the detachable connection, the water inlet pipe 16 and the cleaning vehicle can be separately stored, which is convenient for storage.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
