Description

Technical Field

[0001] This utility model relates to the field of municipal dredging technology, specifically a municipal engineering sewer dredging device. Background Technology

[0002] Municipal engineering sewers refer to the pipes that discharge sewage and rainwater into buildings. They are a type of urban public facility. Sewer dredging involves clearing silt and debris from these pipes to maintain their smooth flow and prevent urban flooding. Existing technology includes a patent (CN 220414487 U) that discloses a municipal engineering sewer dredging device, comprising: a housing; a movable component symmetrically arranged on both sides of the housing and connected to it; and a cleaning mechanism connected to both the housing and the movable component. The cleaning mechanism includes: a scraping component rotatably connected to the housing; a control component located between the housing and the scraping component; and a transmission component located between the control component and the movable component. By configuring the cleaning mechanism and the movable component, not only can the movable component be cleaned, but the system can also control the flow of water in the sewer system. The spacing between the moving components can be adjusted, and the scraping component can also be adjusted, allowing the device to come into contact with the inner walls of sewer pipes of different inner diameters. This enables the device to perform sludge removal operations on sewer pipes of various inner diameters, improving the adaptability of the sludge removal device. The device removes sludge from the inner walls of municipal engineering sewer pipes through the scraping component to achieve sludge removal. However, the sludge removed by the scraping component may be in clumps. Excessive removal of clumps of sludge can lead to blockages. Therefore, we propose a municipal engineering sewer sludge removal device. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This embodiment provides a technical solution: a municipal engineering sewer dredging device, including a housing 1. Three evenly distributed circular track wheels 7 are mounted on the outer side of the housing 1 via a connecting frame. The track wheels 7 can adopt the track wheel structure of the existing D800A dredging robot, and there are three track wheels 7. A connecting shell 3 is provided on the right side of the housing 1. A microcontroller 2 is housed inside the housing 1, and the input terminal of the microcontroller 2 is electrically connected to an external power source. A camera 8 is mounted on the left side of the outer side of the housing 1 via a fixing frame. The camera 8 is bidirectionally electrically connected to the microcontroller 2. The device also includes a display screen 5 located outside the housing 1. A wireless signal receiver 6 is located on the rear side of the display screen 5.

A wireless signal transmitter 9 is located inside the housing 1. The input terminal of the wireless signal transmitter 9 is electrically connected to the output terminal of the microcontroller 2. The wireless signal transmitter 9 and the wireless signal receiver 6 are installed together. When using the device to dredge the municipal sewer, the device itself is first placed inside the municipal sewer pipe. At this time, the outer surfaces of the three track wheels 7 are in contact with the inner wall of the municipal sewer pipe. A motor is installed on the outer side of the lower track wheel 7 (the track wheel 7 is made of...). The device consists of a drive wheel, a driven wheel, and a track. The output shaft of the motor is fixedly connected to the drive wheel of the lower track wheel 7. The rotation of the motor drive shaft drives the track to rotate, and the track contacts the inner wall of the pipe through friction. (The lower track wheel 7 has a drive function, while the other two provide movement support.) This allows the device to move along the inner wall of the municipal sewer pipe. During the dredging process of the municipal sewer pipe, the microcontroller 2 activates the camera 8. The camera 8, based on optical imaging and photoelectric conversion technology, collects light through the lens and focuses it onto the photosensitive element, converting the light signal into a digital signal. The image data is then processed and transmitted to the microcontroller 2 via electrical signals. The microcontroller 2 transmits the image data uploaded by the camera 8 to the wireless signal transmitter 9 via electrical signals. The wireless signal transmitter 9 transmits the signal to the wireless signal receiver 6 via wireless waves. The wireless signal receiver 6 then converts the image data into electrical signals and transmits them to the display screen 5. This allows staff to remotely monitor the dredging status of the municipal engineering sewer pipes using the display screen 5. After the sludge in the municipal engineering sewer pipes is cleared, water is injected into the municipal engineering sewer pipes to allow the sludge to be discharged with the water flow. The device also includes a dredging mechanism 4.

[0020] Dredging mechanism 4: It includes a circular seat 41, a rotating shaft 42, a dredging scraper 43, a protruding blade 44, and a crushing assembly 45. The circular seat 41 is located on the right side of the connecting shell 3. The rotating shaft 42 is rotatably connected to the middle of the circular seat 41 via a bearing. The dredging scraper 43 is located at the right end of the middle of the rotating shaft 42, and the protruding blade 44 is located at the right end of the rotating shaft 42. The crushing assembly 45 is located between the circular seat 41 and the rotating shaft 42. The crushing assembly 45 includes a circular ring 451, a rectangular shell 452, a crushing rod 453, an annular undulating groove 454, a sliding rod 455, and a synchronizing seat 456. The circular ring 451 is located at the left end of the middle of the rotating shaft 42. Four evenly distributed rectangular shells 452 are located on the outer side of the circular ring 451. The crushing rod 453 is slidably connected inside each rectangular shell 452. 53. An annular undulating groove 454 is provided on the left side of the circular seat 41. Four evenly distributed sliding rods 455 are slidably connected inside the annular undulating groove 454. The right end of each sliding rod 455 is rotatably connected to a synchronous seat 456 via a bearing 2. The synchronous seats 456 are fixedly connected to the adjacent crushing rods 453. The crushing assembly 45 also includes an annular shell 457 and a circular seat 458. The circular seat 458 is located at the right end of the middle of the rotating shaft 42. The annular shell 457 is rotatably connected between the circular seat 458 and the circular seat 41 via a large-diameter bearing. The end of each crushing rod 453 away from the center of the circular seat 41 passes through a clearance groove opened on the annular shell 457. The sludge removal mechanism 4 also includes a servo motor 46, which is located on the left side of the circular seat 41. The input terminal of servo motor 46 is electrically connected to the output terminal of microcontroller 2. The output shaft of servo motor 46 is fixedly connected to the left end of rotating shaft 42. Servo motor 46 is located inside connecting housing 3. During device movement, microcontroller 2 starts servo motor 46, causing its output shaft to drive rotating shaft 42 to rotate. Rotating shaft 42 drives the protruding blade 44 to rotate. During the rotation of the protruding blade 44, it removes the silt blocking the middle of the municipal engineering sewer pipe through its own blade surface. At the same time, rotating shaft 42 drives sludge scraper 43 to rotate. During the rotation of sludge scraper 43, it moves along the inner wall of the municipal engineering sewer pipe through its own scraper, thereby scraping off the silt adhering to the wall of the municipal engineering sewer pipe. At the same time, rotating shaft 42 drives ring 451 to rotate. Ring 451 drives rectangular... The rectangular shell 452 rotates, and the slidable engagement between the rectangular shell 452 and the crushing rod 453 drives the crushing rod 453 to rotate synchronously. During the rotation of the crushing rod 453, the sliding rod 455 is driven to rotate through the synchronous seat 456. During the rotation of the sliding rod 455, it continuously moves closer to or away from the center of the device along the undulations of the annular groove 454, so that the crushing rod 453 continuously slides in and out along the corresponding rectangular shell 452 during the rotation of the rotating shaft 42 (during this process, the crushing rod 453 adaptively slides along the avoidance groove on the annular shell 457). When the crushing rod 453 slides out along the corresponding rectangular shell 452, the end of the crushing rod 453 away from the center of the device impacts and crushes the sludge in the corresponding part of the municipal engineering sewer pipe.The annular shell 457, circular seat 41, and circular seat 458 work together to enclose the transmission part of the crushing component 45, preventing silt from entering and interfering with it. This device, through its transmission elements, can separately clean silt from the walls and core of municipal sewer pipes. Simultaneously, the device, through its transmission elements, can automatically impact and crush the silt, reducing the probability of blockages caused by clumps of silt accumulating inside the pipe.

[0021] The working principle of the municipal engineering sewer dredging device provided by this utility model is as follows: When using the device to dredge the municipal engineering sewer, the device itself is first placed inside the municipal engineering sewer pipe. At this time, the outer surfaces of the three track wheels 7 are in contact with the inner wall of the municipal engineering sewer pipe. A motor (the track wheel 7 consists of a drive wheel, a driven wheel, and a track) is installed on the outer side of the lower track wheel 7. The output shaft of the motor is fixedly connected to the drive wheel of the lower track wheel 7. The rotation of the motor drive shaft drives the track to rotate. The track contacts the inner wall of the pipe through friction, realizing the movement of the device along the inner wall of the municipal engineering sewer pipe. During the movement of the device, the microcontroller 2 starts the servo motor 46 to make its output shaft The rotating shaft 42 drives the rotating blade 44 to rotate. During the rotation of the blade 44, the blade surface removes the silt blocking the middle of the municipal sewer pipe. Simultaneously, the rotating shaft 42 drives the sludge scraper 43 to rotate. During the rotation of the sludge scraper 43, the scraper moves along the inner wall of the municipal sewer pipe, scraping off the silt adhering to the wall. At the same time, the rotating shaft 42 drives the ring 451 to rotate, which in turn drives the rectangular shell 452 to rotate. The rectangular shell 452 slides and engages with the breaking rod 453, causing the breaking rod 453 to rotate synchronously. During the rotation of the breaking rod 453, the sliding rod 455 is driven to rotate via the synchronizing seat 456. The device moves towards or away from the center of the device along the undulating annular groove 454, causing the crushing rod 453 to alternately slide in and out along the corresponding rectangular shell 452 during its rotation around the rotating shaft 42 (during this process, the crushing rod 453 adaptively slides along the avoidance groove on the annular shell 457). When the crushing rod 453 slides out along the corresponding rectangular shell 452, the end of the crushing rod 453 away from the center of the device impacts and crushes the sludge in the corresponding part of the municipal engineering sewer pipe. The annular shell 457, round seat 1 41, and round seat 2 458 cooperate to wrap the transmission part of the crushing component 45, preventing sludge from entering and interfering with it. During the sludge removal process of the municipal engineering sewer pipe, the microcontroller 2 is activated. Camera 8, based on optical imaging and photoelectric conversion technology, collects light through a lens and focuses it onto a photosensitive element. After converting the light signal into a digital signal, it processes it and transmits it to the microcontroller 2 as an electrical signal. The microcontroller 2 transmits the image data uploaded by camera 8 to the wireless signal transmitter 9 as an electrical signal. The wireless signal transmitter 9 transmits the signal to the wireless signal receiver 6 as a wireless wave. The wireless signal receiver 6 then converts the image data into an electrical signal and transmits it to the display screen 5, allowing staff to remotely monitor the dredging status of the municipal engineering sewer pipes on the display screen 5. After the sludge in the municipal engineering sewer pipes is cleaned, water is injected into the municipal engineering sewer pipes to allow the sludge to be discharged with the water flow.

[0022] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an MCS-51, the servo motor 46 can be a 60ST-M00630LBX, the display screen 5 can be a JBH686N002, the wireless signal receiver 6 can be an FA233W wireless receiver, the camera 8 can be an MVT-AH36P, and the wireless signal transmitter 9 can be an FA233W wireless transmitter.
