Abstract
Description
Technical Field
[0001] This application relates to the field of municipal engineering technology, and in particular to a device for preventing blockages and clearing silt in municipal road engineering. Background Technology
[0002] Municipal roads are often equipped with sewers and drainage systems. Rainwater washes away dust and other debris from the road surface, carrying them into these systems. Over time, this debris accumulates and forms silt. If the silt buildup is too large, it can affect the water flow rate during drainage. Therefore, regular silt removal is necessary, and the commonly used silt removal equipment is a vacuum truck. When silt settles in drainage pipes, it may harden, contain fibrous materials, or be mixed with stones, making it difficult for the vacuum truck to directly remove it from the pipes, resulting in incomplete silt removal. Summary of the Invention
[0003] To more thoroughly clean drainage pipes, this application provides a municipal road engineering anti-blockage and dredging device.
[0004] The technical solution provided in this application is as follows:
[0005] A municipal road engineering anti-blockage and dredging device includes a base, a traveling component for driving the base to move within a pipe, a first breaking component rotatably connected to the base, a second breaking component rotatably connected to the base, and a power component for providing rotational power to the first breaking component. The first breaking component includes a connecting section connected to the base, a breaking section coaxially connected to the connecting section, and a first spiral blade spirally disposed outside the breaking section. The end of the breaking section away from the connecting section is pointed. The second breaking component includes a breaking sleeve rotatably sleeved outside the connecting section and a second spiral blade spirally disposed outside the breaking sleeve. One end of the breaking sleeve is rotatably connected to the base, and the other end is sealed to the connecting section. A force transmission component is provided between the breaking sleeve and the connecting section for transmitting power so that the breaking sleeve rotates in the opposite direction relative to the connecting section.
[0006] By adopting the above technical solution, before or during suction, the base is first placed into the drain pipe opening, and the walking component drives the entire device downward. At this time, the power component drives the connecting section to rotate clockwise, thereby causing the crushing section to rotate clockwise, crushing and dispersing the sludge. While the crushing section is rotating and crushing, the crushing sleeve rotates counterclockwise under the drive of the force transmission component, thereby breaking the vortex formed by the crushing section, further cutting and dispersing the sludge, thus facilitating the suction truck to pump out the sludge, and allowing the drain pipe to be cleaned more effectively.
[0007] Preferably, the force transmission component includes an intermediate gear rotatably connected to the base, a driving gear fixedly sleeved on the connecting section, and a driven gear ring coaxially fixedly embedded in the crushing sleeve. The intermediate gear meshes externally with the driving gear and internally with the driven gear ring.

[0009] Preferably, the base is embedded with a sewage pipe for connection with a vacuum truck, and the first crushing component is provided with a sewage discharge channel. The sewage discharge channel includes a main channel coaxially opened between the connecting section and the crushing section, a first branch channel connecting the main channel and the outer wall of the crushing section, and a second branch channel connecting the outer wall of the base and the main channel. The base is provided with an annular channel connecting the sewage pipe and the second branch channel. The main channel is provided with a spiral track to assist the sludge to move upward when the first crushing component rotates.
[0010] Preferably, one side of the sewage pipe is connected to a water inlet pipe and a water supply component installed on the sewage suction truck for supplying water to the water inlet pipe. The water inlet pipe is equipped with a one-way valve and an on / off valve. The one-way valve is used to prevent sludge from entering the water inlet pipe.
[0011] Preferably, the walking assembly includes a plurality of walking feet arranged circumferentially along the drain pipe. Each walking foot includes a first rod fixedly connected to the base, a second rod rotatably connected to the first rod, a walking wheel rotatably connected to one end of the second rod, and a motor for driving the walking wheel to rotate. The motor is mounted on the second rod. The end of the first rod away from the base is inclined upward, and the second rod is inclined downward. When the base moves downward relative to the drain pipe, the walking wheel is supported on the inner wall of the drain pipe.
[0012] Preferably, the base is provided with a scraper for scraping dirt off the inner wall of the drain pipe. The scraper is arc-shaped and there are several scrapers arranged along the circumference of the drain pipe. Each wheel corresponds to at least one scraper. One end of the scraper is fixedly connected to the second rod and the other end is spaced apart from the base.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.
[0023] This application discloses a device for preventing blockages and clearing silt in municipal road engineering. For example... Figure 1 As shown, the dredging device includes a base 1, a traveling assembly 2, a first crusher 3, a second crusher 4, a power unit 5, a suction truck 6, and a traction assembly. The traction assembly is mounted on the suction truck 6 to pull the base 1. The traveling assembly 2 drives the base 1 to move inside the drain pipe to be dredged. The first crusher 3, the second crusher 4, and the power unit 5 are all mounted on the base 1. During operation, the suction truck 6 pulls the base 1 through the traction assembly. Under the action of the traveling assembly 2, the base 1 moves inside the drain pipe. Then, the first crusher 3 and the second crusher 4 reverse direction to generate cutting force and vortex, cutting and cleaning the sludge inside the drain pipe. Finally, the suction truck 6 discharges the cleaned-off sludge out of the pipe, completing the dredging process.
[0024] Specifically, such as Figure 1As shown, the traction assembly includes a winch 7, the winch 7 body is fixedly installed on the vacuum truck 6, and the traction steel wire of the winch 7 is connected to the base 1. The traveling assembly 2 includes several traveling feet 8 arranged circumferentially along the drain pipe, and the traveling feet 8 are evenly spaced on the base 1. Figure 2 As shown, the walking foot 8 includes a first rod 9 fixedly connected to the base 1, a second rod 10 rotatably connected to the first rod 9, a walking wheel 11 rotatably connected to one end of the second rod 10, and a motor for driving the walking wheel 11 to rotate. With the inlet of the drain pipe at the top and the outlet at the bottom, the first rod 9 is inclined upwards at the end furthest from the base 1, and the second rod 10 is inclined downwards. The motor is mounted on the second rod 10.
[0025] During operation, the base 1 is first placed into the drain pipe inlet. The first rod 9 and the second rod 10 are rotated until the traveling wheel 11 is supported on the inner wall of the drain pipe. Then, the traveling wheel 11 rotates, causing the base 1 to move downwards along the drain pipe. At this time, the friction between the drain pipe wall and the traveling wheel 11 is upward, giving the end of the second rod 10 with the traveling wheel 11 an upward tendency to move, making the traveling wheel 11 more stably supported on the inner wall of the drain pipe. When the base 1 moves to the bottom of the drain pipe and can no longer move, the traveling wheel 11 rotates in the opposite direction, giving the base 1 an upward tendency. At this time, the friction between the drain pipe wall and the traveling wheel 11 is downward, giving the end of the second rod 10 with the traveling wheel 11 a downward tendency to move, causing the second rod 10 to fold towards the first rod 9, causing the traveling wheel 11 to leave the inner wall of the drain pipe and be stably stretched upwards by the traction component, reducing the resistance it needs to overcome to move upwards.
[0026] like Figure 2 As shown, the first crushing component 3 includes a connecting section 12 connected to the base 1, a crushing section 13 coaxially fixedly connected to the connecting section 12, and a first spiral blade 14 spirally disposed outside the crushing section 13. The power component 5 can be a motor, and the power component 5 is fixedly installed on the base 1. The power component 5 is used to connect to the connecting section 12 to provide power to the connecting section 12. The end of the crushing section 13 away from the connecting section 12 is pointed. The second crushing component 4 includes a crushing sleeve 15 rotatably sleeved outside the connecting section 12 and a second spiral blade 16 spirally disposed outside the crushing sleeve 15. One end of the crushing sleeve 15 is rotatably connected to the base 1, and the other end is sealed to the connecting section 12 through a sealed bearing 17. The second spiral blade 16 has the same rotation direction as the first spiral blade 14. The outer diameter of the connecting section 12 is smaller than the outer diameter of the crushing section 13, and the outer diameter of the crushing sleeve 15 is the same as the outer diameter of the crushing section 13.
[0027] like Figure 2 and Figure 3As shown, a force transmission component is provided between the crushing sleeve 15 and the connecting section 12. The force transmission component includes an intermediate gear 18 rotatably connected to the base 1, a driving gear 19 fixedly sleeved on the connecting section 12, and a driven gear ring 20 coaxially fixedly embedded in the crushing sleeve 15. The intermediate gear 18 meshes externally with the driving gear 19 and internally with the driven gear ring 20. Several intermediate gears 18 are arranged circumferentially along the driven gear ring 20.
[0028] As the base 1 moves downwards within the drain pipe, the power from the power component 5 is transmitted to the connecting section 12 and the crushing section 13, causing the crushing section 13 to rotate and generate a vortex to break up the dirt. The vortex can remove some of the dirt from the inner wall of the drain pipe. When the connecting section 12 rotates, it drives the drive gear 19 to rotate, which in turn drives the driven gear ring 20 to rotate under the transmission of the intermediate gear 18. The driven gear ring 20 rotates in the opposite direction to the drive gear 19. This causes the second crushing component 4 to rotate in the opposite direction relative to the crushing section 13, achieving reverse vortex generation and secondary crushing, thus improving sludge removal and sewage discharge.
[0029] like Figure 2 As shown, to facilitate the removal of contaminants and better form a vortex, a sewage discharge channel is provided on the first crushing component 3, and a sewage discharge pipe 22 for connection with the vacuum truck 6 is embedded in the base 1. The sewage discharge channel includes a main channel 23 coaxially formed between the connecting section 12 and the crushing section 13, a first branch channel 24 connecting the main channel 23 and the outer wall of the crushing section 13, and a second branch channel 25 connecting the main channel 23 and the outer wall of the connecting section 12. An annular channel 21 is formed on the base 1 along the circumference of the outer wall of the connecting section 12. Several first branch channels 24 and second branch channels 25 are provided along the circumference of the main channel 23. The annular channel 21 communicates with the second branch channel 25.
[0030] like Figure 2 As shown, the main channel 23 is equipped with a spiral track 26 to assist the sludge in moving upwards when the first crusher 3 rotates. Figure 1 As shown, a water inlet pipe 30 and a water supply device installed on the vacuum truck 6 are connected to one side of the sewage pipe 22 to supply water to the water inlet pipe 30. The water supply device can be a water pump, a water tank with its own water pressure, etc. The water inlet pipe 30 is equipped with a one-way valve and an on / off valve. The one-way valve is used to prevent sludge from entering the water inlet pipe 30.
[0031] When removing sludge, water can be first injected into the sewage channel through the inlet pipe 30 to moisten various parts of the sludge, thus facilitating the formation of subsequent vortices. When the dirt has been roughly broken up and mixed, it is introduced into the sewage pipe 22 through the sewage channel, thereby completing the cleaning of the drainage pipe. The operation is convenient.
[0032] like Figure 2As shown, to facilitate the cleaning of silt and the movement of the base 1, a scraper 27 for scraping dirt from the inner wall of the drain pipe is provided on the outer periphery of the base 1. The scraper 27 is arc-shaped and has several pieces arranged along the circumference of the drain pipe, with at least one scraper 27 corresponding to each wheel 11. One end of the scraper 27 is fixedly connected to the second rod 10, and the other end is spaced apart from the base 1. The scraper 27 is located below the wheel 11, and the end of the scraper 27 away from the base 1 has a flexible layer for contacting the inner wall of the drain pipe; this flexible layer can be made of rubber. This allows the scraper 27 to clean the dirt from the inner wall of the drain pipe to a certain extent as the base 1 moves downwards, facilitating the movement of the wheel 11. Simultaneously, the first crushing component 3 and the second crushing component 4 have already cleaned the inner wall of the drain pipe to a certain extent, further facilitating the cleaning by the scraper 27 and the movement of the wheel 11.
[0033] like Figure 2 As shown, to reduce the probability of silt accumulating on the crushing sleeve 15, a cam 29 is fixedly sleeved on the outer wall of the connecting section 12, and a striking block 28 is provided on the inner wall of the crushing sleeve 15. The striking block 28 is connected to the crushing sleeve 15 through an elastic element 31. The striking block 28 is slidably connected to the crushing sleeve 15 radially. When the cam 29 rotates past the striking block 28, the crushing sleeve 15 and the connecting section 12 vibrate under force. This makes it difficult for silt to adhere to the crushing sleeve 15, and at the same time, it has a vibration force to disperse the silt, making it easier for the silt and dirt to be dispersed and discharged.
[0034] In other final embodiments, to accommodate more drain pipes, the breaking section 13 includes straight sections and pointed sections. Several straight sections are provided, and adjacent straight sections are detachably connected by bolts or other snap-fit methods. The pointed section is detachably connected to the end of the straight section furthest from the connecting section 12. The diameter of the straight section closer to the pointed section is smaller. The number of straight sections can be selected and the length of the breaking section adjusted according to actual needs, allowing the device to accommodate drain pipes of more sizes. It also facilitates the cleaning of dirt entangled on the breaking section.
[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
