Description

Technical Field

[0001] This invention relates to the technical field of sewage pipe testing, and specifically to a device for testing underground sewage pipe networks. Background Technology

[0002] Underground sewage pipe networks are a crucial component of urban infrastructure, playing a vital role in the collection and transportation of urban sewage. With the accelerating pace of urbanization, the coverage of underground sewage pipe networks is continuously expanding, highlighting problems such as aging, damage, and blockages in these networks. This places higher demands on the regular inspection and maintenance of these networks. Currently, underground sewage pipe network inspection mainly relies on pipe inspection robots. These devices are typically equipped with camera modules, allowing them to penetrate deep into the pipe network to acquire images of the inner walls, assisting workers in identifying defects.

[0003] However, existing underground sewage pipe network detection devices generally have the following defects: the inner wall of the sewage pipe network is often covered with debris. These obstructions will cover up defects such as damage and cracks in the inner wall of the pipe network, resulting in blurry images captured by the camera module. This makes it impossible to accurately identify the actual damage to the pipe network, which will affect the detection accuracy and may even cause missed detections or false detections. Summary of the Invention

[0004] The purpose of this invention is to provide an underground sewage pipe network detection device to overcome the above-mentioned defects in the prior art.

[0005] An underground sewage pipe network detection device includes a frame, a drive mechanism and a detection and cleaning mechanism, wherein a camera 1 and a camera 2 are respectively installed at both ends of the frame; The drive mechanism is mounted on the frame and is used to drive the rollers thereon to move inside the sewage pipe; The detection and cleaning mechanism is mounted on the frame and is used to clean the sewage pipe to be inspected and to blow air to clean the scraper after cleaning.

[0006] Preferably, the frame includes end plates, guide rods and fixing plates, with a plurality of guide rods evenly distributed between the two end plates, and two fixing plates symmetrically arranged on the guide rods.

[0007] Preferably, the driving mechanism further includes a drive screw, a movable plate, a drive plate, a connecting plate, a motor 1, and a motor 2. A drive screw is rotatably connected between adjacent end plates and fixed plates. The movable plate is helically connected to the drive screw via a screw nut and slidably connected to a guide rod. One end of the drive plate is hinged to the fixed plate via a pin, and the other end of the drive plate is rotatably connected to a roller via a connecting shaft. Motor 1 is mounted on the drive plate, and its output shaft is provided with a bevel gear 2 that meshes with a bevel gear 1 on the connecting shaft. One end of the connecting plate is hinged to the movable plate via a pin, and the other end of the connecting plate is hinged to the drive plate via a pin. A rotating shaft is rotatably connected between the two fixed plates. Both ends of the rotating shaft are respectively provided with drive gear 2 that meshes with the drive gear 1 on the drive screw. Motor 2 is mounted on the side of one of the fixed plates, and its output shaft is connected to one of the drive screws.

[0008] Preferably, the detection and cleaning mechanism further includes a third motor, support plates, a telescopic airbag, a transmission plate, and an air nozzle. The third motor is installed on the outside of one of the end plates. A rotating cylinder rotatably connected to the end plate is provided on the output shaft of the third motor. Two support plates are symmetrically arranged on the rotating cylinder. A slide rod 1 and a slide rod 2 are slidably connected on each support plate. A baffle plate 1 and a baffle plate 2 are respectively provided at the ends of slide rod 1 and slide rod 2. A spring 1 and a spring 2 are respectively sleeved on slide rod 1 and slide rod 2, located between the scraper and the support plate. The telescopic airbag is sleeved on slide rod 2. One end of the upper part is connected to the baffle plate, and the other end of the telescopic airbag is connected to the support plate. The slide rod 1 and slide rod 2 are connected to the same scraper. The scraper is provided with a pressing slope. The support plate is rotatably connected to the drive gear 3 through the drive shaft. The drive gear 3 meshes with the rack on the slide rod 1. The drive shaft is provided with a side plate. The support plate is hinged to the swing plate through a pin. One end of the transmission plate is hinged to the side plate through a pin, and the other end of the transmission plate is hinged to the swing plate through a pin. The air nozzle is located on the swing plate and is connected to the telescopic airbag through a hose.

[0009] Preferably, there are three guide rods.

[0010] Preferably, the first camera and the second camera are respectively mounted on two end plates.

[0011] Preferably, the support plate has an overall "L" shaped structure.

[0012] Preferably, the air nozzle is fixed to the swing plate by a fixing ring.

[0013] Preferably, the side of the air nozzle facing the scraper has a flat structure.

[0014] The beneficial effects achieved by this invention are as follows: 1. This application utilizes cameras 1 and 2 at both ends of the frame, driven by a drive mechanism, to perform real-time imaging and inspection of the inner wall of the pipeline network in the forward and rear directions, achieving full-range, blind-spot-free inspection of the pipeline network. This facilitates real-time observation of damage, blockages, and other conditions on the inner wall of the pipeline network by staff. When debris, silt, or other obstructions affecting the clarity of the inspection are detected on the inner wall of the pipeline network, motor 3 is activated to drive the scraper to rotate and quickly remove the obstructions, ensuring clear images captured by the camera module during subsequent inspections. This effectively avoids missed or false detections caused by obstructions and significantly improves the reliability of pipeline network inspection.

[0015] 2. This application utilizes the coordinated operation of the telescopic airbag, air nozzle, swing plate, transmission plate, and slide rod assembly in the cleaning mechanism. After the scraper completes the cleaning operation on the inner wall of the pipe network and the device is removed from the sewage pipe, the scraper disengages from the inner wall of the pipe network and extends outward under the elastic force of springs one and two. This causes slide rod two to move and compress the telescopic airbag, generating compressed gas. The compressed gas is delivered to the air nozzle through a hose. Simultaneously, the rack on slide rod one drives the drive gear three to rotate, which in turn drives the swing plate to swing back and forth through the side plate and transmission plate. This, in turn, causes the air nozzle to swing, blowing the compressed gas onto the scraper surface. This efficiently blows off the debris attached to the scraper, achieving automatic air blowing cleaning by the scraper and preparing for the next scraper cleaning of the pipe network.

The motor 52 is mounted on the outside of one of the end plates 11. The output shaft of the motor 52 is provided with a rotating drum 53 that is rotatably connected to the end plate 11. Two "L"-shaped support plates 54 are symmetrically provided on the rotating drum 53. Each support plate 54 has... The slide rod 55 and slide rod 56 are slidably connected. The ends of slide rod 55 and slide rod 56 are respectively provided with baffle plate 551 and baffle plate 561.

Additionally, a drive gear 57 is rotatably connected to the support plate 54 via a drive shaft. The drive gear 57 meshes with the rack 571 on the slide rod 55. A side plate 58 is provided on the drive shaft. A swing plate 581 is hinged to the support plate 54 via a pin. One end of the transmission plate 582 is hinged to the side plate 58 via a pin, and the other end of the transmission plate 582 is hinged to the swing plate 581 via a pin. An air nozzle 59 is provided on the swing plate 581 and is connected to the telescopic airbag 563 via a hose 591. The air nozzle 59 is fixed to the swing plate 581 via a fixing ring. The side of the air nozzle 59 facing the scraper 51 has a flat structure. The compression of the telescopic airbag 563 causes compressed gas to be blown through the air nozzle 59 onto the cleaning surface of the scraper 51, which can more effectively clean the surface of the scraper 51 and improve cleaning efficiency. Detailed implementation methods and principles: During operation, the device is placed at the sewage pipe opening to be tested. The scraping inclined surface 511 on the scraper 51 causes the sliding rod 55 and sliding rod 56 on the scraper 51 to move on the support plate 54. The spring 552 and spring 562 are compressed, causing the scraper 51 to enter the sewage pipe. Under the elastic force of the spring 552 and spring 562, the scraper 51 comes into contact with the inner wall of the sewage pipe. Next, start motor 48. The output shaft of motor 48 drives the drive screw 42 connected to it to rotate. The drive gear 421 at the end of the drive screw 42 drives the drive gear 471 at both ends of the rotating shaft 47 to rotate, which in turn drives the other drive screw 42 and drive gear 421 to rotate synchronously. During the rotation of the drive screw 42, the moving plate 43 moves linearly along the guide rod 12. When the moving plate 43 moves, it drives the drive plate 44 to rotate through the connecting plate 49, so that the rollers 41 on the drive plate 44 synchronously unfold towards the inner wall of the pipe network until the rollers 41 are tightly attached to the inner wall of the sewage pipe, completing the contact between the device and the sewage pipe. At this time, motor 48 is turned off. Next, start motor 45. The output shaft of motor 45 drives bevel gear 46 to rotate. Bevel gear 46 drives bevel gear 411 and roller 41 to rotate. The two cameras take real-time pictures and detect the inner wall of the pipeline in the forward direction and the rear direction of the device, respectively, to achieve full-process pipeline detection without blind spots, which makes it easy for staff to observe the damage, blockage and other conditions of the inner wall of the pipeline in real time. When debris, silt, or other obstructions are detected at a certain location on the inner wall of the pipe network, affecting the clarity of the detection, motor 3 52 is started. The output shaft of motor 3 52 drives the rotating drum 53 to rotate. The L-shaped support plate 54 on the rotating drum 53 rotates synchronously with the rotating drum 53. The scraper 51 scrapes away the debris and silt on the inner wall of the sewage pipe. When the scraper 51 completes the cleaning operation at a certain position, and the device is removed from the sewage pipe, the scraper 51 disengages from the sewage pipe. Under the action of spring 1 552 and spring 2 562, the scraper 51 extends outward. The telescopic airbag 563 generates compressed gas during the movement of slide bar 2 56. The compressed gas is delivered to the air nozzle 59 through hose 591. The air nozzle 59 blows the compressed gas onto the surface of the scraper 51. At the same time, the rack 571 on slide bar 1 55 drives the drive gear 3 57 to rotate. Through the transmission plate 582 on the side plate 58, the swing plate 581 is driven to swing back and forth, causing the air nozzle 59 on the swing plate 581 to swing and blow off the debris attached to the scraper 51, thus realizing the automatic air blowing cleaning of the scraper 51.
