Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage pipe cleaning technology, and in particular to a rainwater and sewage pipe cleaning device. Background Technology

[0002] A stormwater and sewage pipe cleaning device is a specialized piece of equipment used for cleaning and maintaining stormwater and sewage pipes. These pipes are prone to blockage, damage, or poor drainage due to the accumulation of dirt, debris, or sediment during daily use, affecting their normal drainage function. The stormwater and sewage pipe cleaning device uses a variety of methods, including cleaning, dredging, pulverizing, and vacuuming, to ensure unobstructed flow, improve work efficiency, and extend the pipes' lifespan.

[0003] Currently, traditional rainwater and sewage pipe cleaning devices typically have a powerful suction function to remove sediment, debris, branches, sludge, etc. from the pipes, ensuring that the pipes are not blocked. However, larger or harder debris (such as branches, large pieces of sludge, etc.) can directly enter the suction system and get stuck in the suction pipes, causing a significant decrease in suction efficiency and thus reducing the overall cleaning effect. The accumulation of debris in the suction pipes can also affect air circulation, resulting in insufficient suction capacity and poor pipe cleaning effect. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a rainwater and sewage pipe cleaning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rainwater and sewage pipe cleaning device, comprising a housing, a bus fixedly connected to one end of the housing, an air suction pipe fixedly connected to the housing, the bus connecting the air suction pipe to a power supply assembly, dust suction ports provided at the end of the housing away from the bus and on the side wall, a motor fixedly installed inside the housing, multiple sets of pulverizing blades fixedly installed on the side wall of the motor shaft, the multiple sets of pulverizing blades being staggered, a pulverizing chamber provided inside the housing, the pulverizing blades located within the pulverizing chamber, a dust suction chamber provided inside the housing, the dust suction chamber being connected to the dust suction pipe, multiple dust passage holes provided inside the housing, the multiple dust passage holes being circumferentially arrayed within the housing, the dust passage holes being located between the pulverizing chamber and the dust suction chamber, and connected to both the pulverizing chamber and the dust suction chamber, and multiple sets of track mechanisms provided on the outer wall of the housing.

[0006] Preferably, the outer wall of the outer shell is provided with a plurality of inner grooves, and the plurality of inner grooves are distributed in a circumferential array on the outer wall of the outer shell, and the plurality of track mechanisms correspond to the plurality of inner grooves respectively.

[0007] Preferably, each of the multiple inner grooves is rotatably connected to a connecting rod, and the connecting rod is fixedly connected to the inner groove by a spring. The end of the connecting rod away from the inner groove is fixedly connected to the corresponding track mechanism.

[0008] Preferably, the motor shaft is fixedly connected to a cleaning wheel, the cleaning wheel is located outside the housing, the cleaning wheel is rotatably connected to a plurality of cleaning rods, the plurality of cleaning rods are distributed in a circumferential array on the side wall of the cleaning wheel, and the cleaning rods are fixedly connected to the inner wall of the cleaning wheel by a spring.

[0009] Preferably, a guide wheel is rotatably connected to the end of the cleaning rod away from the cleaning wheel, and the rotation direction of the guide wheel is the same as that of the cleaning wheel.

[0010] Preferably, a scraper is provided at the end of the cleaning rod away from the cleaning wheel, and the tip of the scraper is flush with the guide wheel.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] 1. This utility model uses a suction port to draw dirt into a grinding chamber. Through multiple cuts and refinements by the grinding blades, the dirt becomes smaller, effectively improving the processing efficiency. It ensures that even viscous or large particles of dirt can be pulverized, facilitating subsequent suction and discharge. The staggered arrangement of multiple sets of grinding blades avoids clogging problems caused by a single blade. At the same time, the existence of the grinding chamber allows larger dirt particles to be effectively broken up, preventing dirt from causing blockages or blockages in the pipes and channels of the dust collection system, thereby helping to improve processing efficiency.

[0013] 2. This utility model, by setting a connecting rod and a spring, allows the device to automatically adjust the position of the track mechanism according to the inner diameter of the pipe, ensuring that the track of the track mechanism always fits against the inner wall of the pipe without the need for manual adjustment or replacement of parts. In addition, the cleaning rod can also be finely adjusted according to the actual size of the pipe to adapt to pipes with different inner diameters, ensuring that the guide wheel always fits against the inner wall of the pipe. This allows the equipment to adapt to various pipe specifications without the need for frequent adjustments or replacement of parts, thereby enhancing the practicality of the equipment.

[0014] 3. This utility model, by setting up cleaning rods and cleaning wheels, etc., the cleaning rods follow the rotation of the cleaning wheels to break up and peel off the dirt in the forward direction of the outer shell, efficiently handling large areas or continuously distributed dirt, reducing cleaning dead corners, and the scraper tip scrapes off stubborn dirt attached to the pipe wall. The combination of rotational cleaning and scraping speeds up the cleaning speed, ensures that there is no dirt residue, and thus enhances the cleaning effect of the equipment.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1 to 4 A stormwater and sewage pipe cleaning device includes a housing 4, with a bus 1 fixedly connected to one end of the housing 4. The outer wall of the bus 1 is covered with a wear-resistant material to help reduce wear caused by friction with the inner wall of the pipe during cleaning, thus extending the service life of the device. An air suction pipe is fixedly connected to the housing 4, and the bus 1 connects the air suction pipe to a power supply assembly. One end of the housing 4 connected to the bus 1 is the end of the device. Multiple inner grooves 7 are provided on the outer wall of the housing 4, arranged in a circumferential array. Each inner groove 7 is rotatably connected to a connecting rod 2, and a second spring 71 is fixedly connected to the connecting rod 2 and the inner groove 7. The second spring 71 is located inside the inner groove 7. A track mechanism 3 is provided at the end of the connecting rod 2 away from the inner groove 7. When the housing 4 enters the stormwater and sewage pipe, the track mechanism 3 adjusts according to the inner diameter of the pipe. Link 2 rotates under the action of the pipe wall, and spring 2 71 pulls link 2, so that the track of track mechanism 3 always fits against the pipe wall. After track mechanism 3 is started, housing 4 moves along the inner wall of the pipe and performs cleaning work at the same time. Track mechanism 3 can adaptively adjust according to pipes with different inner diameters, which improves the versatility and adaptability of the device. There is no need to change different cleaning tools for pipes of different sizes. Because track mechanism 3 can fit tightly against the inner wall of the pipe, the device can move stably along the inner wall of the pipe after starting, which not only improves the thoroughness of cleaning, but also ensures the stability and continuity of the cleaning process, thereby improving the overall cleaning efficiency. When housing 4 stops moving in the pipe due to failure or other emergencies, it can be pulled out of the pipe directly through bus 1.

[0022] A motor 8 is fixedly installed inside the outer casing 4. A cleaning wheel 5 is fixedly connected to the shaft of the motor 8. The cleaning wheel 5 is located outside the outer casing 4. Multiple cleaning rods 6 are rotatably connected to the cleaning wheel 5. These cleaning rods 6 are arranged in a circumferential array on the side wall of the cleaning wheel 5. A spring 51 is fixedly connected to the inner wall of the cleaning rod 6. A guide wheel 62 is rotatably connected to the end of the cleaning rod 6 furthest from the cleaning wheel 5. The rotation direction of the guide wheel 62 is the same as that of the cleaning wheel 5. A scraper 61 is provided at the end of the cleaning rod 6 furthest from the cleaning wheel 5. The tip of the scraper 61 is flush with the guide wheel 62. The scraper 61 is connected to the cleaning rod 6 via the spring 51. Capable of adapting to pipes of different inner diameters, the cleaning rod 6 finely adjusts itself according to the actual size of the pipe when the cleaning device enters the pipe, ensuring that the guide wheel 62 always fits tightly against the inner wall of the pipe. This adaptive feature greatly improves cleaning efficiency and coverage, and reduces cleaning blind spots caused by differences in pipe size. The rotating motion of multiple cleaning rods 6 can effectively break up and peel off dirt in the direction of pipe movement. The scraper 61 can scrape off stubborn stains attached to the pipe wall, ensuring thorough cleaning of the inner wall of the pipe. The rolling contact of the guide wheel 62 is gentler than direct friction, which can ensure the cleaning effect while protecting the pipe from damage.

[0023] Dust suction ports 41 are provided on the end of the outer casing 4 away from the bus 1 and on its side wall. Multiple sets of pulverizing blades 9 are fixedly installed on the side wall of the motor 8's shaft, and these blades are staggered. A pulverizing chamber 44 is provided inside the outer casing 4, with the pulverizing blades 9 located within it. A dust suction chamber 42 is also provided inside the outer casing 4, connected to a dust suction pipe. Multiple dust passage holes 43 are provided inside the outer casing 4, arranged in a circumferential array within it. These holes are located between the pulverizing chamber 44 and the dust suction chamber 42, and are connected to both. Dirt is sucked into the pulverizing chamber 44 through the dust suction ports 41, and the dirt, pulverized and refined by the pulverizing blades 9, is then discharged from the dust suction ports 41. The dirt is drawn into the suction chamber 42 through the dust passage 43 and finally sucked out of the rainwater and sewage pipe by the suction pipe in the bus 1. The multiple sets of shredders 9 are staggered to ensure that the dirt is fully and evenly shredded in the shredder chamber 44, which improves the processing efficiency. The separate design of the shredder chamber 44 and the suction chamber 42 avoids the dirt from directly entering the suction system during the shredding process, reducing the risk of system blockage. The dust passage 43 not only ensures the smooth flow of dirt from the shredder chamber 44 to the suction chamber 42, but also improves the stability and durability of the overall structure. The dirt shredded by the shredders 9 is smaller in volume and easier to be sucked in and sent out by the suction system, which improves the suction efficiency.

[0024] In this invention, the device enters the pipe through the inlet of the rainwater and sewage pipe. Bus 1 connects the suction pipe and power supply assembly, which is externally wrapped with a wear-resistant textile material. Guide wheel 62 and track mechanism 3 contact the pipe wall and are pressed down to adapt to the inner diameter of the pipe. Under the tension of spring 51 and spring 71, guide wheel 62 and track mechanism 3 remain in close contact with the pipe wall. The track in track mechanism 3 rotates at a constant speed, propelling the entire device forward. Motor 8 drives cleaning wheel 5 and pulverizing blade 9 to rotate. As cleaning wheel 5 rotates, cleaning rod 6 rotates, breaking up and peeling off dirt in the forward direction. Scraper 61 has its tip flush with guide wheel 62 and scrapes off dirt attached to the pipe wall, ensuring cleaning quality while preventing dirt from obstructing the device's normal movement. The fallen dirt is collected at the suction ports 41 located at the front and sides of the outer casing 4. The dirt is drawn into the pulverizing chamber 44, ensuring the cleanliness of the cleaning work while preventing the accumulation of dirt from affecting the normal operation of the device. This ensures that the device can perform cleaning work in pipe sections under different conditions. Multiple sets of staggered pulverizing blades 9 pulverize and refine the dirt entering the pulverizing chamber 44. The refined dirt is drawn into the suction chamber 42 through the dust passage 43, preventing large pieces of dirt from clogging the inside of the device, ensuring the continuous cleaning work, reducing the failure rate, and finally being sucked into the suction pipe in the bus 1 and sent out of the rainwater and sewage pipe. The device continues to move forward until it comes out from another pipe opening of the rainwater and sewage pipe, completing the cleaning work of the entire rainwater and sewage pipe. When the device encounters a sudden failure or other special situation, the staff can pull the bus 1 to pull the device out of the rainwater and sewage pipe to prevent the device from getting stuck in the rainwater and sewage pipe and increasing the difficulty of cleaning.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
