[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0016] Refer to Figures 1 to 4 As shown, the present invention provides a municipal pipeline sediment sludge treatment device, including a reamer nozzle 1 for cleaning the sludge inside the municipal pipeline. A baffle assembly 2 is installed on the reamer nozzle 1 to reduce the spread of the odor generated by the sludge inside the municipal pipeline to the outside, preventing the odor generated by the sludge from spreading to the outside and causing harm to human health, environmental safety, and workplace management. The baffle assembly 2 includes an outer frame plate 201 for protecting the internal device. A first fixing frame 202 is installed inside the outer frame plate 201. The first fixing frame 202 expands and lies flat at the mouth of the municipal pipeline to reduce the spread of the odor generated by the sludge inside the pipeline to the outside. Four push-pull rods 204 are connected to the periphery of the first fixing frame 202. The push-pull rods 204 are used to push the first fixing frame 202 to expand. One end of the four push-pull rods 204 is commonly connected to a connecting plate 205, and the connecting plate 205 is used to connect and transmit power to the four push-pull rods 204. A first magnet block 207 is installed inside the outer frame plate 201. The first magnet block 207 is used to magnetically attract a second magnet block 208. A second magnet block 208 is magnetically attracted to one side of the first magnet block 207. The second magnet block 208 magnetically attracts push rods 209 on both sides. The second magnet block 208 drives the push rods 209 to move. One end of the push rod 209 is connected to a second fixing frame 212, and the push rod 209 drives the second fixing frame 212 to expand; When construction workers place the reamer nozzle 1 into the pipe opening and then push the connecting plate 205 forward, the connecting plate 205 pushes the four push rods 204 to move and expand in four directions. Thus, the four push rods 204 drive the first fixing frame 202 to expand and spread flat to block the municipal pipe opening, reducing the odor generated by the sludge inside the pipe from spreading to the outside, preventing the odor generated by the sludge from spreading to the outside, which may cause harm to human health, environmental safety, and workplace management. The baffle assembly 2 can be externally connected to a suction device to collect the odor inside the pipe, better reducing the odor generated by the sludge inside the pipe from spreading to the outside; When the fixing frame 202 expands and spreads flat to block the municipal pipe opening, the construction worker starts the reamer nozzle 1. When the reamer nozzle 1 drives the second magnet block 208 away from the first magnet block 207, the second magnet block 208 is no longer connected to the first magnet block 207, and the push rod 209 is no longer magnetically attracted to the second magnet block 208. The two side push rods 209 push out the second fixing frame 212 to contact the inner wall of the municipal pipe, assisting in fixing the baffle assembly 2 and preventing the external conveying pipe from shifting when the reamer nozzle 1 moves, which may cause the first fixing frame 202 to shift and affect the flat blocking of the first fixing frame 202 at the municipal pipe opening; Refer to Figures 5 to 7As shown, a fixed component 3 is installed on the reamer nozzle 1. The fixed component 3 is used to stabilize the reamer nozzle 1 inside the municipal pipeline to ensure that the reamer nozzle 1 cleans the sludge inside the municipal pipeline. It includes four groups of brackets 301 that penetrate through the outer frame plate 201. In the initial position when the work has not started, one side of the four groups of brackets 301 penetrates through the outer frame plate 201, and the outer frame plate 201 holds the four groups of brackets 301. When not working, it is convenient to store the four groups of brackets 301. One side of the bracket 301 is connected to a damping rod 302. When not working, when the four groups of brackets 301 are stored in the outer frame plate 201, the second spring 311 inside the damping rod 302 is in a compressed state, and the second spring 311 also drives the damping rod 302 to be in a compressed state. When the construction worker starts the reamer nozzle 1 and the reamer nozzle 1 moves forward, the four groups of brackets 301 quickly break away from the outer frame plate 201, and the second spring 311 inside the damping rod 302 quickly rebounds, driving the damping rod 302 to extend. Thus, the damping rod 302 drives one side of the bracket 301 to move outward and fix it inside the municipal pipeline. A second mounting seat 304 is fixed on the reamer nozzle 1. The second mounting seat 304 is used to connect the gear 303 and adjust the opening and closing angle of one side of the bracket 301. A gear 303 rotates on the second mounting seat 304, and one end of the bracket 301 is connected to the gear 303. When one side of the bracket 301 moves outward, it will drive the gear 303 to rotate. One side of the bracket 301 is connected to a pressing plate 305. The bracket 301 drives the pressing plate 305 to move downward for power transmission. One side of the pressing plate 305 is slidably connected to a fourth magnet block 306. The bracket 301 drives the pressing plate 305 to move downward. The back of the fourth magnet block 306 is provided with an inclined surface, and the pressing plate 305 pushes the fourth magnet block 306 forward along the inclined surface. Four groups of nozzles 307 are movably installed on the fourth magnet block 306. The contact surface between the fourth magnet block 306 and the four groups of nozzles 307 is set as an inclined surface that slopes upward to change the angle of the nozzles 307; When the construction worker starts the reamer nozzle 1 and the reamer nozzle 1 moves forward, the four groups of brackets 301 quickly break away from the outer frame plate 201, and the second spring 311 inside the damping rod 302 quickly rebounds, driving the damping rod 302 to extend. Thus, the damping rod 302 drives one side of the bracket 301 to move outward and fix it inside the municipal pipeline, enabling the four groups of brackets 301 to adapt to the sizes of different municipal pipelines through the extension of the damping rod 302, thereby adjusting the opening and closing size of the bracket 301, making the bracket 301 always move along the inner diameter of the pipeline, and being able to spray water on the inner diameter of the pipeline, avoiding the situation that due to gravity, the bracket 301 is at the lower part of the pipeline, resulting in a small spraying area and the inability to spray the two sides and the top inside the pipeline; The four groups of brackets 301 can, through the extension of the damping rod 302, adapt to the sizes of different municipal pipelines. While doing so, one side of the bracket 301 moves outward, driving the gear 303 to rotate. The bracket 301 drives the abutting plate 305 to move downward. There is an inclined surface on the back of the fourth magnet block 306, and the abutting plate 305 pushes the fourth magnet block 306 forward along the inclined surface. The fourth magnet block 306 changes the angle of the nozzle 307 through the inclined surface. According to the size of the municipal pipeline, the opening and closing of one side of the bracket 301 change following the size of the municipal pipeline. How much the other side of the bracket 301 drives the abutting plate 305 to move downward is how much the fourth magnet block 306 is pushed forward by the abutting plate 305, thereby changing the angle of the nozzle 307. The dredging efficiency is improved, and the damage rate of the pipeline inner wall is reduced. While improving the dredging effect, the service life of the pipeline is significantly extended. Because most devices adopt the direct injection method, although the impact force of the direct injection method is concentrated, the water flow coverage is limited, and it is difficult to simultaneously handle the sludge and attachments on the inner wall of the pipeline. Especially when facing complex pipe diameters or stubborn dirt, direct injection may cause excessive erosion in local areas while insufficient cleaning in other areas. By adjusting the injection angle, the water flow can form a fan-shaped or diffused injection, expanding the coverage area and improving the overall cleaning efficiency. An appropriate inclination angle can make the water flow impact the sludge on the side wall and bottom of the pipeline at the same time, reducing cleaning dead corners; In addition, it is supplemented that the device is applicable when the maximum inner diameter of the municipal pipeline is such that the opening and closing angle of the four groups of brackets 301 is 90 degrees. When the opening and closing angle of the bracket 301 has reached 90 degrees but it has not been fixed to the inner wall yet, construction workers need to use a larger model of the device for construction. The angle of the nozzle 307 is adjusted through the opening and closing angle of the bracket 301. Small-diameter municipal pipelines are suitable for a spraying angle of 30 degrees - 45 degrees, while large-diameter pipelines require an angle of more than 60 degrees to ensure full coverage; While the reamer nozzle 1 moves forward, after the bracket 301 has opened and closed and fixed the municipal pipeline, the fourth magnet block 306 attracts the second magnet block 208 to move forward. The second magnet block 208 drives the block 214 to just move to one side of the gear 303, and the block 214 blocks the gear 303, preventing the sludge on the inner wall of the municipal pipeline from squeezing the bracket 301 when the reamer nozzle 1 moves inside the municipal pipeline, causing the bracket 301 to close and affecting the cleaning of the sludge inside the municipal pipeline by the reamer nozzle.

[0017] In an alternative embodiment, the baffle assembly 2 as a whole moves on the external pipeline of the reamer nozzle 1. A push-pull sleeve 206 is provided on the connecting plate 205, and construction workers push the push-pull sleeve 206 to drive the connecting plate 205 to move on the external pipeline of the reamer nozzle 1.

[0018] In an alternative embodiment, first mounting seats 203 are fixedly installed around the first fixing frame 202. The first fixing frame 202 is connected to the push-pull rod 204 through the first mounting seats 203. Four groups of first mounting seats 203 are fixedly installed around the connecting plate 205. The connecting plate 205 is connected to the push-pull rod 204 through the first mounting seats 203. The construction worker pushes the connecting plate 205 forward. The connecting plate 205 pushes the four groups of push-pull rods 204 to adjust the angle towards the first mounting seats 203. The four groups of push-pull rods 204 move and expand in four directions. Thus, the four groups of push-pull rods 204 also adjust the angle through the first mounting seats 203. The four groups of push-pull rods 204 drive the first fixing frame 202 to expand and flatten to block the municipal pipeline opening, reducing the odor generated by the sludge inside the pipeline from spreading to the outside and preventing the odor generated by the sludge from spreading to the outside, which may cause harm to human health, environmental safety, and workplace management.

[0019] In an alternative embodiment, a telescopic rod 213 is connected inside the outer frame plate 201. One end of the telescopic rod 213 is fixedly connected to the first fixing frame 202. The telescopic rod 213 is used to connect the first fixing frame 202. When the first fixing frame 202 expands, the telescopic rod 213 extends simultaneously to assist the first fixing frame 202 in expanding and fixing.

[0020] In an alternative embodiment, one side of the second magnet block 208 extends through the outer frame plate 201 for installation. Two groups of grooves are provided inside the outer frame plate 201. One end of the push rod 209 extends through the groove for installation, and a third magnet block 215 is connected to one end of the push rod 209. A fixing block is fixedly installed on the push rod 209. A first spring 210 is provided on the push rod 209. One end of the first spring 210 is fixedly connected to one end of the groove, and one end of the first spring 210 is fixedly connected to the fixing block. In the initial position, the push rod 209 is connected to the second magnet block 208 through the third magnet block 215. When the push rod 209 moves backward, the push rod 209 squeezes the first spring 210 on one side of the groove through the fixing block. When the reamer nozzle 1 drives the second magnet block 208 away from the first magnet block 207, the second magnet block 208 is no longer connected to the first magnet block 207, and the push rod 209 is no longer magnetically attracted to the second magnet block 208 through the third magnet block 215. The first spring 210 undergoes elastic deformation and rebounds. The first spring 210 drives the two side push rods 209 to move. The two side push rods 209 push out the second fixing frame 212 to contact the inner wall of the municipal pipeline, assisting in fixing the baffle assembly 2 and preventing the external conveying pipeline from shifting when the reamer nozzle 1 moves, which may cause the first fixing frame 202 to shift and affect the first fixing frame 202 from flattening and blocking the municipal pipeline opening.

[0021] In an alternative embodiment, a second spring 311 is provided inside the damping rod 302. One side of the second spring 311 is fixedly connected to the reamer nozzle 1. Both ends of the damping rod 302 are connected to the second mounting seat 304 and are respectively connected to the damping rod 302 and the reamer nozzle 1 through the second mounting seat 304. A roller 312 is provided on one side of the bracket 301. When the construction worker starts the reamer nozzle 1 and the reamer nozzle 1 moves forward, the four groups of brackets 301 quickly disengage from the outer frame plate 201. The second spring 311 inside the damping rod 302 quickly rebounds, driving the extension of the damping rod 302. Thus, the damping rod 302 drives one side of the bracket 301 to move outward through the second mounting seat 304 and is fixed inside the municipal pipeline through the roller 312. When the reamer nozzle 1 moves forward to clean the sludge inside the municipal pipeline, the four groups of brackets 301 will also move forward with the reamer nozzle 1 through the roller 312 to stabilize the operation of the reamer nozzle 1.

[0022] In an alternative embodiment, a clamping block 214 is provided on one side of the second magnet block 208. A tooth groove is provided on one side of the clamping block 214. The tooth groove of the clamping block 214 is slidably connected to the gear 303. While the reamer nozzle 1 moves forward and the brackets 301 are opened and closed to fix the municipal pipeline, the fourth magnet block 306 attracts the second magnet block 208 to move forward. The second magnet block 208 drives the clamping block 214 just to move to one side of the gear 303, and the tooth groove of the clamping block 214 catches the gear 303, preventing the reamer nozzle 1 from having sludge on the inner wall of the municipal pipeline squeezing the brackets 301 and causing the brackets 301 to close when the reamer nozzle 1 moves inside the municipal pipeline, which affects the cleaning of the sludge inside the municipal pipeline by the reamer nozzle.

[0023] In an alternative embodiment, a limiting frame 309 is provided on one side of the nozzle 307. An L-shaped connecting rod 310 is fixedly connected to the limiting frame 309. One side of the L-shaped connecting rod 310 is fixedly connected to the reamer nozzle 1. A third mounting seat 308 is provided on the water spray pipe of the reamer nozzle 1. The third mounting seat 308 is connected to the limiting frame 309. A flexible hose is provided at the connection between the limiting frame 309 and the water spray pipe of the reamer nozzle 1. An inclined surface is also provided inside the limiting frame 309. The inclined surface inside the limiting frame 309 has the same slope as the inclined surface of the fourth magnet block 306. The limiting frame 309 is used to limit the rotation of the nozzle 307 so that the nozzle 307 will not swing backward, changing the water spray angle of the nozzle 307 and affecting the treatment of the sludge in the municipal pipeline by the device. The third mounting seat 308 is used to adjust the water spray angle of the nozzle 307.

[0024] Working principle: When construction workers place the reamer nozzle 1 at the pipe opening and then push the connecting plate 205 forward, the connecting plate 205 pushes the four push rods 204 to move and expand in four directions. As a result, the four push rods 204 drive the first fixing frame 202 to expand and spread flat to block the municipal pipe opening, reducing the spread of the odor generated by the sludge inside the pipe to the outside world and preventing the odor generated by the sludge from spreading to the outside world, which may cause harm to human health, environmental safety, and workplace management. When the fixing frame 202 expands and spreads flat to block the municipal pipe opening, the construction worker starts the reamer nozzle 1. When the reamer nozzle 1 drives the second magnet block 208 away from the first magnet block 207, the second magnet block 208 is no longer connected to the first magnet block 207, and the push rod 209 is no longer magnetically attracted to the second magnet block 208. The two push rods 209 on both sides push out the second fixing frame 212 to contact the inner wall of the municipal pipe, assisting in fixing the baffle assembly 2 and preventing the displacement of the external conveying pipe when the reamer nozzle 1 moves, which may cause the displacement of the first fixing frame 202 and affect the flat blocking of the first fixing frame 202 at the municipal pipe opening. When the construction worker starts the reamer nozzle 1 and the reamer nozzle 1 moves forward, the four brackets 301 quickly disengage from the outer frame plate 201, and the second spring 311 inside the damping rod 302 quickly rebounds, driving the extension of the damping rod 302. As a result, the damping rod 302 drives one side of the bracket 301 to move outward and fix it inside the municipal pipe. The four brackets 301 can adapt to the sizes of different municipal pipes through the extension of the damping rod 302, thereby adjusting the opening and closing size of the brackets 301 so that the brackets 301 always move along the inner diameter of the pipe, and water can be sprayed on the inner diameter of the pipe, avoiding the situation that the brackets 301 are under the influence of gravity and are located below the pipe, resulting in a small spraying area and the inability to spray the inner sides and top of the pipe. While the four brackets 301 can adapt to the sizes of different municipal pipes through the extension of the damping rod 302, one side of the bracket 301 moves outward, driving the gear 303 to rotate. The bracket 301 drives the pressing plate 305 to move downward. The back of the fourth magnet block 306 is provided with an inclined surface, and the pressing plate 305 pushes the fourth magnet block 306 forward along the inclined surface. The fourth magnet block 306 changes the angle of the nozzle 307 through the inclined surface. According to the size of the municipal pipe, the opening and closing of one side of the bracket 301 change following the size of the municipal pipe. How much the other side of the bracket 301 drives the pressing plate 305 to move downward, the fourth magnet block 306 is pushed forward by the pressing plate 305 by the same amount, thereby changing the angle of the nozzle 307, improving the dredging efficiency, reducing the damage rate of the pipe inner wall, enhancing the dredging effect, and significantly extending the service life of the pipe. While the reamer nozzle 1 moves forward, the bracket 301 opens and closes to fix the municipal pipeline. The fourth magnet block 306 attracts the second magnet block 208 to move forward. The second magnet block 208 drives the latch 214 to just move to one side of the gear 303. The latch 214 catches the gear 303 to prevent sludge on the inner wall of the municipal pipeline from squeezing the bracket 301 when the reamer nozzle 1 moves inside the municipal pipeline, causing the bracket 301 to close and affecting the cleaning of the sludge inside the municipal pipeline by the reamer nozzle.

[0025] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
