Description

Technical Field

[0001] The invention relates to the technical field of silt removal equipment, and in particular to a silt removal device for the inner wall of a highway drainage culvert. Background Art

[0002] Drainage culverts refer to water pipes buried underground, which can be used as waterways below the ground level. They are one of the important structures in highway and railway projects. The sewage on the road surface is discharged through the drainage culverts. Underground drainage culverts are usually circular in diameter and laid underground. They are mainly responsible for the drainage of rainwater, sewage, etc. However, the inner wall of the drainage culvert is prone to sludge adhesion after long-term use. As the sludge accumulates for a long time, it is easy to cause the drainage pipe to be blocked, thus affecting its discharge of sewage. In order to ensure the normal operation of the drainage culvert, it is necessary to use dredging mechanisms to clean and maintain it regularly, clean up the sludge and other wastes accumulated inside it, and dredge the pipeline. For sludge that has accumulated for a long time, it adheres more tightly to the inner wall of the culvert, and the long-term adhesion of the sludge makes it difficult to remove.

[0003] At present, the dredging of drainage culverts still mainly relies on manpower, which is inefficient and requires a lot of work, and is inconvenient to clean at locations far away from the drainage outlets.

[0004] There are also some occasions where pipe desilting equipment is used to clean drainage culverts, usually by shoveling, high-pressure suction of silt, etc. However, there are still some disadvantages in their use, such as: 1. During dredging, the sludge is not filtered and the sludge containing a large amount of sewage is usually directly pumped out, which is inconvenient for subsequent treatment and transportation; 2. During the dredging process, the working surface of the shovel-type dredging device is small and cannot perform circumferential cleaning on the inner wall of the culvert; 3. The high-pressure sludge suction method is not suitable for sludge consolidation. It needs to be removed with water flow, which wastes water resources. The above disadvantages will lead to poor dredging effect, low efficiency and shortened equipment service life. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a highway drainage culvert inner wall dredging device, which can rotate and scrape away the silt adhered to the inner wall of the culvert, and crush and filter the cleaned silt to achieve mud-water separation, facilitate subsequent transportation and treatment, and enable the silt to be smoothly discharged to the outside of the drainage culvert.

[0021] The dredging method of the inner wall dredging device of a highway drainage culvert of the present invention is as follows: Start the mobile vehicle and the camera to move the mobile vehicle to the position where the drainage culvert is to be cleaned, start the second driving device to drive the guide rod to rotate, and the guide sleeve moves toward the distal end along the guide rod, thereby driving the distal end of the adjustment rod to open radially, so that the working surface of the cleaning plate fits the inner wall of the drainage culvert, and at the same time, the movable rod of the telescopic support rod assembly extends outward to support the cleaning plate, and the second driving device stops running when the cleaning plate contacts the inner wall of the drainage culvert; The first driving device is started to rotate the stirring frame, and the entire sludge cleaning assembly is driven to rotate at the same time. The drill assembly clears the blockage inside the drainage culvert during rotation, and the cleaning plate uses the scraping convex strips on its surface to scrape the sludge on the inner wall of the drainage culvert. The camera records the cleaning process and the internal situation of the drainage culvert in real time; Turn on the suction pump to suck the cleaned sludge into the treatment tube from the sludge suction port. Large pieces of sludge are broken by the stirring of the stirring rack, and the rotation of the stirring rack drives the sludge to rotate to form a vortex, which rushes to the filter component. After filtration and separation by the filter component, the sewage flows out from the drain port and the sludge is discharged from the sludge discharge port. The first driving device drives the scraper device to scrape and clean the surface of the primary filter plate and the separation filter plate to prevent the sludge from clogging the filter eyes; and under the impact of the water flow, the impact cleaning component impacts and cleans the separation filter plate and the screening plate; The sludge flows from the sludge discharge port into the sludge discharge pipe through the plugging assembly. The sludge is stirred by the stirring frame to form a vortex with impact force, which impacts the plugging disk at the entrance of the plugging cylinder, causing the plugging disk to overcome the supporting force of the elastic support member and deflect, thereby opening the entrance of the plugging cylinder and allowing the sludge to fall into the sludge discharge pipe. In the absence of sludge impact, the elastic support member is reset to restore support for the plugging disk and seal the plugging cylinder. After the drainage culvert is cleaned, the first drive device and the suction pump are turned off, and the second drive device is rotated in the opposite direction, driving the guide rod to reverse, and the guide sleeve moves toward the proximal end of the guide rod. The distal end of the adjustment rod is radially contracted, driving the cleaning plate to retract toward the guide rod, and at the same time, the movable rod of the telescopic support rod assembly is contracted and reset; the mobile vehicle moves in the opposite direction to exit the drainage culvert, and the camera is turned off.

[0022] The present invention has the following beneficial effects: The highway drainage culvert inner wall desilting device is provided with a stirring frame, and a first driving device is used to drive the stirring frame to rotate in the processing barrel, so as to break up the extracted large pieces of sludge, and use its rotational force to turn up the sludge, thereby preventing the sludge from accumulating in the processing barrel, which is beneficial to the subsequent processing and discharge of the sludge; The filter assembly is used to achieve at least two layers of filtration, thereby improving the mud-water separation effect and making the separation of water and mud more thorough; a mud scraping device and a striking cleaning assembly are provided to clean the filter assembly, prevent the filter holes from being blocked by mud, and improve the filtration effect; and the filter assembly plays a good supporting role for the stirring assembly, thereby improving the stability of the stirring assembly operation; The drill bit of the sludge cleaning component is rotated to drill the stubborn sludge or sludge blockage in the drainage culvert; the sludge adhering to the inner wall of the drainage culvert is rotated and cleaned by the scraping convex strips on the working surface of the cleaning plate, and the cleaning plate is moved along the drainage culvert under the movement of the mobile vehicle; under the action of the second driving device, the cleaning plate can fit the inner wall of the drainage culvert when working, and can be retracted when not working; the camera can be set to record the situation in the drainage culvert and the progress of dredging in real time; the protective sleeve is set to protect the second driving device to prevent it from directly contacting sewage, affecting its normal operation or shortening its service life; the limit plate is set at the front end of the guide rod, which can block the sludge in the drainage culvert to prevent excessive adhesion of sludge on the guide rod, causing the guide sleeve to jam when moving; The setting of the plugging cylinder assembly can effectively adjust the opening and closing of the mud discharge port, and can effectively prevent the sludge from flowing back while ensuring the smooth discharge of the sludge.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 13 , the present invention provides a technical solution: like Figure 1 As shown, a highway drainage culvert inner wall desilting device comprises a mobile vehicle 1, and a sludge processing component 2 and a sludge cleaning component 3 installed on the mobile vehicle 1.

[0027] The sludge treatment component 2 includes a treatment cylinder 21 , a stirring component 22 and a filtering component 23 .

[0028] The treatment barrel 21 is mounted and fixed on the mobile vehicle 1. The mobile vehicle 1 can drive the sludge treatment component 2 and the sludge cleaning component 3 to move inside the drainage culvert to perform cleaning work, thereby ensuring that the inside of the drainage culvert is cleaned comprehensively and thoroughly. An arc-shaped groove 12 for installing the treatment barrel 21 is provided on the body 11 of the mobile vehicle 1, and at least one fixing member 13 is provided. The treatment barrel 21 is fixed by the fixing member 13 to facilitate maintaining the stability of the treatment barrel 21 on the mobile vehicle 1 and prevent the treatment barrel 21 from falling when the mobile vehicle 1 moves. The body 11 is provided with a crawler-type walking mechanism 14 for walking. In other embodiments, other types of walking mechanisms can also be used. Since the mobile vehicle 1 and its walking mechanism adopt the existing technology and are not an improved part of the present invention, they are not described here.

[0029] like Figure 2 As shown, the treatment barrel 21 is divided into a stirring chamber 211 and a filtering chamber 212. The treatment barrel 21 is provided with a mud extraction port 213 corresponding to the stirring chamber 211, and the mud extraction port 213 is installed with a suction pump (omitted in the figure) and a mud extraction pipe 214; a drainage port 215 is provided corresponding to the filtering chamber 212, and the drainage port 215 is connected to a drainage pipe 216; a mud discharge port 218 is provided at a portion of the stirring chamber 211 close to the filtering chamber 212. The inlet of the mud extraction pipe 214 points to the forward direction of the dredging device and is provided close to the sludge cleaning component 3. The mud discharge port 218 is provided with a plugging component 217 to prevent the sludge from reversely entering the treatment barrel 21 from the mud discharge port 218; the plugging component 217 is connected to the mud discharge pipe 219, and the sludge is discharged to the outside of the drainage culvert by using the mud discharge pipe 219. A suction pump is provided outside the drainage culvert and connected to the mud discharge pipe 219 to facilitate the discharge of sludge. The treatment barrel 21 is used to collect sludge. The suction pump extracts the sewage and sludge inside the drainage culvert, and uses the sludge extraction pipe 214 to transport the sludge and sewage to the treatment barrel 21 for treatment. The extraction work of the sludge extraction pipe 214 is adjusted with the movement of the mobile vehicle 1, thereby avoiding the accumulation of sludge inside the drainage culvert to affect the circulation of water.

[0030] When the suction pump is installed, it is fixedly installed outside or inside the treatment barrel 21. When it is installed inside the treatment barrel 21, it is limited to not affecting the normal operation of the stirring assembly 22. The inlet of the suction pump is connected to the mud suction pipe 214, and the outlet is connected to the mud suction port 213.

[0031] The stirring assembly 22 is installed in the stirring chamber 211 , and comprises a stirring frame 221 rotatably connected to the processing cylinder 21 and a first driving device 222 for controlling the rotation of the stirring frame 221 .

[0032] The stirring frame 221 includes a stirring rod 2211 and stirring blades 2212 installed on the stirring rod 2211. The stirring blades 2212 are at least arranged in one group along the length direction of the stirring rod 2211. Each group of stirring blades 2212 is provided with a plurality of stirring blades 2212, which are evenly distributed around the outer periphery of the stirring rod 2211 in the circumferential direction.

[0033] In this embodiment, the first driving device 222 is a motor.

[0034] One end of the stirring rod 2211 is connected to the power output shaft of the first driving device 222 through a coupling (omitted in the figure), and the other end is rotatably connected to the processing cylinder 21 through a bearing. The stirring rod 2211 can rotate under the drive of the first driving device 222.

[0035] The rotation of the stirring frame 221 is used to stir and crush the sludge entering the treatment barrel 21, so that the sewage and sludge are discharged from the drain port 215 and the sludge discharge port 218 respectively. The rotation of the stirring frame 221 can promote the circulation of the sludge, speed up the circulation speed of the sludge inside the treatment barrel 21, and avoid the accumulation of sludge inside the treatment barrel 21.

[0036] like Figure 5-9 As shown, the filter assembly 23 is fixedly connected to the filter chamber 212 of the treatment cylinder 21 for filtering the sewage. The filter assembly 23 filters the sewage multiple times inside the treatment cylinder 21 to intercept the sludge and separate the sludge and sewage more thoroughly.

A gap is left between the separation filter disc 232 and the screening filter disc 233, and they are connected and fixed by a support column 234. The outer circumference of the support column 234 is evenly distributed with a striking cleaning component 235, which can strike and clean the separation filter disc 232 and the screening filter disc 233 to prevent the filter holes of the separation filter disc 232 and the screening disc 233 from being blocked by silt, thereby affecting the flow of sewage.

[0040] like Figure 5-6 As shown, the striking cleaning assembly 235 includes a plurality of bases 2351 and two striking rods 2352 installed on the bases 2351 and opened at a certain angle. The free ends of the striking rods 2352 are respectively installed with striking heads 2353. The two striking rods 2352 are connected by elastic bands 2354 near the striking heads 2353. Under normal conditions, there is a distance between the striking heads 2353 and the separation filter disc 232 and the screening filter disc 233. Under the impact of water flow, the striking heads 2353 knock and clean the separation filter disc 232 and the screening filter disc 233 to prevent the filter holes from being blocked.

[0041] like Figure 7-8 As shown, the filter assembly 23 is also provided with a scraper device 236, which includes a scraper plate 2361 and an annular cleaning sleeve 2362 for installing the scraper plate 2361.

The connecting sleeve 2363 is connected to the power output shaft of the first driving device 222. The scraper plate 2361 is fitted with the separation filter disc 232 or the primary filter disc 231. The cleaning sleeve 2362 can rotate under the drive of the first driving device 222, so that the scraper plate 2361 rotates to scrape the mud.

[0042] When the first driving device 222 is a single-head motor, the cleaning sleeve 2362 is arranged on the outside of the primary filter disc 231, and the cleaning sleeve 2362 is connected and fixed to the stirring rod 2211 of the stirring frame 221 or the power output shaft of the first driving device 222 through the connecting sleeve 2363. The outer peripheral surface of the cleaning sleeve 2362 is approximately fitted with the inner wall of the treatment cylinder 21, and the cleaning sleeve 2362 can rotate relative to the primary filter disc 231; the scraper plates 2361 of the scraper device 236 are respectively connected with horizontal extension rods 2365, and the ends of the extension rods 2365 are connected and fixed to the second group of scraper plates 2361. The second group of scraper plates 2361 are arranged to fit the disc surface of the partition filter disc 232, and rotate under the drive of the cleaning sleeve 2362. The scraper plates 2361 scrape and clean the primary filter disc 231 and the partition filter disc 232 respectively.

[0043] like Fig. 9 As shown, when the first driving device 222 is a double-headed motor, its first power output shaft is connected to the stirring frame 221, and its second power output shaft is connected and fixed to the cleaning sleeve 2362 through the connecting sleeve 2363. The outer peripheral surface of the cleaning sleeve 2362 is approximately fitted with the inner wall of the treatment cylinder 21. The first group of scraper blades 2361 fits with the surface of the separation filter disc 232, and the second group of scraper blades 2361 fits with the surface of the primary filter disc 231. The two groups of scraper blades 2361 are connected by an extension rod 2365. Under the action of the second power output shaft, the cleaning sleeve 2362 drives the scraper blades 2361 to scrape and clean the primary filter disc 231 and the separation filter disc 232. In order to improve the stability of the scraper device 236, the second power output shaft and the separation filter disc 232 can be connected through a bearing.

[0044] The filter assembly 23 can support the stirring assembly 22 while realizing the filtering function, thereby increasing the bearing capacity of the stirring frame 221 during rotation and preventing the stirring rod 2211 from bending during rotation and affecting its stirring function.

[0045] In order to improve the stability of the stirring assembly 22 , the first driving device 222 can be fixedly connected to the separation filter disc 232 while being fixedly installed on the primary filter disc 231 .

[0046] like Figure 3-4 As shown, the sealing assembly 217 includes a sealing cylinder 2171 , a sealing disk 2172 , an elastic support member 2173 and a sealing sleeve 2174 .

[0047] The top opening of the sealing cylinder 2171 is connected and fixed to the mud discharge port 218, and the bottom opening is connected and fixed to the mud discharge pipe 219; a sealing disk 2172 is rotatably installed at the top opening of the sealing cylinder 2171, and an elastic support member 2173 is provided under the sealing disk 2172, and the elastic support member 2173 is connected and fixed to the inner wall of the sealing cylinder 2171; a sealing sleeve 2174 is installed at the connection between the sealing cylinder 2171 and the mud discharge port 218, and reinforcing ribs are provided inside the sealing sleeve 2174, and the reinforcing ribs divide the sealing sleeve 2174 into a plurality of mud outlets, and the impact force of the sludge on the sealing disk 2172 can overcome the supporting force of the elastic support member 2173, so that the sealing disk 2172 rotates to discharge the sludge.

[0048] The sealing disk 2172 is fixedly connected to a rotating shaft 2172-1, which is symmetrically arranged and perpendicular to the central axis of the sealing disk 2172; the rotating shaft 2172-1 is rotatably connected to the side wall of the sealing cylinder 2171, so that the sealing disk 2172 can be flipped up and down with the rotating shaft 2172-1 as the center. When the sealing disk 2172 is in a horizontal state, the mud discharge port 218 is blocked. When the mud impacts the sealing disk 2172 to deflect it, the mud discharge port 218 opens, and the sludge is discharged from the mud discharge port 218 and falls into the mud discharge pipe 219 and is discharged to the outside of the drainage culvert.

[0049] Two elastic support members 2173 are provided, symmetrically arranged on both sides of the rotating shaft 2172-1. The elastic support member 2173 comprises an arc-shaped elastic support rod 2173-1, and a mounting seat 2173-2 connected to the bottom end of the arc-shaped elastic support rod 2173-1, the mounting seat 2173-2 is connected and fixed to the inner wall of the blocking cylinder 2171, and a support rod 2173-3 is provided at the top end of the arc-shaped elastic support rod 2173-1. The support rods 2173-3 on the two elastic support members 2173 are arranged in an inverted eight-shaped shape. When the elastic support rod 2173-1 does not undergo elastic deformation, the support rod 2173-3 contacts the bottom surface of the blocking disk 2172.

[0050] Under the support of the arc-shaped elastic support rod 2173-1, the two support rods 2173-3 are respectively supported on the bottom surface of the sealing plate 2172, so that the sealing plate 2172 is maintained in a horizontal state. When sludge enters the cleaning barrel 21, under the action of the stirring assembly 22, the sludge rushes to the mud discharge port 218 with a certain impact force, impacting the sealing plate 2172. The impact force overcomes the supporting force of the arc-shaped elastic support rod 2173-1, causing it to undergo elastic deformation, and the sealing plate 2172 deflects to open the mud discharge port 218, thereby allowing the sludge to be discharged; after the sludge is discharged, the arc-shaped elastic support rod 2173-1 is reset to support the sealing plate 2172, so that the sealing plate 2172 returns to a horizontal state and seals the mud discharge port 218, thereby preventing the residual sewage or sludge in the treatment barrel 21 from leaking from the inside of the sealing assembly 217, thereby ensuring the sealing of the treatment barrel 21 when not in use.

[0051] like Figure 10-13 As shown, the sludge cleaning assembly 3 is rotatably connected to the treatment barrel 21 and can be rotated to clean sludge under the action of the dynamic driving device. In this embodiment, the sludge cleaning assembly 3 is driven to rotate by the first driving device 222.

[0052] The sludge cleaning assembly 3 includes a second driving device 31 , a cleaning plate assembly 32 , a camera assembly 33 and a drill assembly 34 .

[0053] A protective sleeve 311 is provided on the outside of the second driving device 31, and the protective sleeve 311 is sleeved on the outside of the main body of the second driving device 31. The protective sleeve 311 is connected to the stirring rod 2211 of the stirring frame 221 through a coupling, and is rotatably connected to the treatment barrel 21 under the action of the bearing. Under the action of the first driving device 222, the sludge cleaning assembly 3 can rotate as a whole.

[0054] The cleaning plate assembly 32 can be radially opened or contracted under the action of the second driving device 31. When it is in the open state, the working surface of the cleaning plate assembly 32 can fit the inner wall of the drainage culvert and rotate to scrape mud under the action of the first driving device 222.

[0055] The cleaning plate assembly 32 includes a guide rod 321 , a guide sleeve 322 , a cleaning plate 323 , a telescopic support rod assembly 324 , an adjustment rod 325 and a limiting plate 326 .

[0056] The guide rod 321 is installed on the power output shaft of the second drive device 31, and the distal end of the guide rod 321 is fixedly connected to the limiting disk 326; the guide sleeve 322 is threadedly connected to the guide rod 321; a plurality of cleaning plates 323 are arranged, which are evenly distributed on the outside of the guide rod 321 in the circumferential direction, and the cleaning plate 323 is an arc-shaped plate, which is adapted to the inner diameter of the drainage culvert, and the working surface of the cleaning plate 323 is evenly distributed with mud scraping convex strips 3231; the telescopic support rod assembly 324 is installed on the distal end of the guide rod 321, and is arranged close to the limiting disk 326. The main body of the telescopic support rod assembly 324 is connected and fixed to the guide rod 321, and the movable rod 3241 of the telescopic support rod assembly 324 is connected and fixed to the cleaning plate 323; a plurality of adjusting rods 325 are arranged, one end of which is hinged to the guide sleeve 322 through a hinge seat, and the other end is hinged to the cleaning plate 323 through a hinge seat. The guide rod 321 can rotate under the action of the second driving device 31 .

[0057] When the guide sleeve 322 is located at the proximal end of the guide rod 321, the adjusting rod 325 and the guide rod 321 are in a nearly parallel state, the cleaning plate 323 is close to the guide rod 321, and the movable rod 3241 of the telescopic support rod assembly 324 is in a retracted state; when the guide sleeve 322 moves toward the distal end of the guide rod 321, the angle between the adjusting rod 325 and the guide rod 321 increases, driving the cleaning plate 323 to move radially to fit the inner wall of the drainage culvert, and the movable rod 3241 of the telescopic support rod assembly 324 extends radially to form radial support for the cleaning plate 323.

[0058] The camera assembly 33 is mounted on the front end of the cleaning plate assembly 32, and includes a camera mounting seat 331, a camera 332 and a housing 333. At least one camera 332 is provided, which is fixedly mounted on the ends of the camera mounting seat 331, and is embedded and fixed with the housing 333 of the limiting plate 326 through the camera mounting seat 331. The circuit board and other components of the camera 332 are sealed inside the camera mounting seat 331, and the peripheral wall of the camera mounting seat 331 is provided with a hole for embedding the camera 332. The camera 332 is a mature product on the market, which at least has the functions of video recording and storage.

[0059] The drill assembly 34 is installed and fixed at the front end of the camera assembly 33. The drill assembly 34 includes a drill rod 341 and a plurality of drilling blades 342 arranged along the length of the drill rod 341. Each drilling blade group is provided with no less than three, and is evenly distributed around the drill rod 341 in the circumferential direction. When the drilling blades 342 and the drill rod 341 are installed, a certain angle is formed to form a conical drill structure. The drill rod 341 passes through the center of the housing 333 and is connected and fixed to the limit plate 326 and the guide rod 321.

[0060] In other embodiments, the sludge cleaning assembly 3 may also be provided with a third driving device separately for driving the rotation of the entire sludge cleaning assembly 3, and the third driving device is connected and fixed to the mobile vehicle 1 or the processing cylinder 21. The advantage of providing the third driving device is that the sludge cleaning assembly 3 and the stirring frame 221 can be controlled separately, but the disadvantage is that the weight of the equipment is increased. Whether to use the first driving device 222 or the third driving device to drive the entire sludge cleaning assembly 3 is determined according to actual needs or specific use environment.

[0061] The cleaning plate 323 rotates to clean the inner wall of the drainage culvert, and moves along the drainage culvert to clean as the mobile vehicle 1 moves, so that the cleaning plate 323 can remove stubborn sludge to prevent sludge from remaining on the inner wall of the drainage culvert and affecting the circulation of water; the limiting plate 326 rotates with the guide rod 321, so that the limiting plate 326 blocks the sludge inside the drainage culvert and protects the guide rod 321 to prevent excessive adhesion of sludge on the guide rod 321, which causes the guide sleeve 322 to get stuck when moving. At the same time, the limiting plate 326 is used to limit the moving distance of the guide sleeve 322 to prevent the guide sleeve 322 from falling off the guide rod 321.

[0062] Embodiment 2, a dredging method of a highway drainage culvert inner wall dredging device of the present invention is as follows: Start the mobile vehicle 1 and the camera 332, move the mobile vehicle 1 to the position where the drainage culvert is to be cleaned, start the second driving device 31 to drive the guide rod 321 to rotate, and the guide sleeve 322 moves toward the distal end along the guide rod 321, thereby driving the distal end of the adjustment rod 325 to open radially, so that the working surface of the cleaning plate 323 fits the inner wall of the drainage culvert, and at the same time, the movable rod 3241 of the telescopic support rod assembly 324 extends outward to support the cleaning plate 323, and the second driving device 31 stops running when the cleaning plate 323 contacts the inner wall of the drainage culvert; The first driving device 222 is started to rotate the stirring frame 221, and the entire sludge cleaning assembly 3 is driven to rotate at the same time. The drill assembly 34 clears the blockage inside the drainage culvert during rotation, and the cleaning plate 323 uses the scraping convex strips 3231 on its surface to scrape the sludge on the inner wall of the drainage culvert. The camera 332 records the cleaning process and the internal situation of the drainage culvert in real time. The suction pump is turned on, and the cleaned sludge is sucked into the processing tube 21 through the sludge suction pipe 214. The large pieces of sludge are broken under the stirring treatment of the stirring frame 221, and the stirring frame 221 rotates to drive the sludge to rotate to form a vortex with a large flow rate, which rushes to the filter assembly 23. After filtering and separation by the filter assembly 23, the sewage flows out from the drain port 215, and the sludge is discharged from the sludge discharge port 218; At the same time, the first driving device 222 drives the scraper 2361 to scrape and clean the surfaces of the primary filter disc 231 and the separation filter disc 232 to prevent the sludge from clogging the filter eyes; and under the impact of the water flow, the striking rod 2352 and the striking head 2353 swing axially with the base 2351 as the fulcrum, and are elastically constrained by the elastic belt 2354, so that the striking head 2353 strikes the separation filter disc 232 and the screening disc 233 to complete the cleaning work; The sludge flows from the sludge discharge port 218 through the plugging cylinder 2171 into the sludge discharge pipe 219. The sludge is stirred by the stirring frame 221 to form a vortex with impact force, which has a greater impact on the plugging disk 2172 at the entrance of the plugging cylinder 2171, causing the plugging disk 2172 to deflect and overcome the supporting force of the arc-shaped elastic support rod 2173-1, thereby opening the entrance of the plugging cylinder 2171 and allowing the sludge to fall into the sludge discharge pipe 219. In the absence of sludge impact, the arc-shaped elastic support rod 2173-1 is reset to restore support for the plugging disk 2172 and seal the plugging cylinder 2171. After the drainage culvert is cleaned, the first drive device 222 and the suction pump are turned off, and the second drive device 31 is rotated in the opposite direction, driving the guide rod 321 to reverse, and the guide sleeve 322 moves toward the proximal end of the guide rod 321. The distal end of the adjustment rod 325 is radially contracted, driving the cleaning plate 323 to retract toward the guide rod 321, and at the same time, the movable rod 3241 of the telescopic support rod assembly 324 is contracted and reset; the mobile vehicle 1 is moved in the opposite direction to exit the drainage culvert, and the camera 332 is turned off.
