Description

Technical Field

[0001] This utility model relates to the technical field of drainage pipeline inspection equipment, and in particular to a top-driven drainage pipeline inspection equipment. Background Technology

[0002] Urban drainage networks and auxiliary drainage pipelines of large-scale water conservancy projects are massive in scale, and their daily operation and maintenance and safety assurance needs continue to grow. With the development of smart cities, the requirements for intelligent operation and maintenance of pipeline networks are increasing. Against this background, how to break through the limitations of traditional models and explore efficient and low-cost unmanned inspection innovation models has become a core challenge that urgently needs to be solved.

[0003] Currently, drainage pipeline inspection robots generally use tracked inspection vehicles that travel at the bottom of the pipeline as carriers to carry out unmanned inspection tasks. They have many limitations: (1) They are easily affected by silt, water accumulation and obstacles, and the equipment has insufficient obstacle crossing ability and poor scene adaptability; (2) They have low intelligence, low disease identification accuracy, lack of targeted scene data training, and low information integration and transmission efficiency; (3) They have high service costs. Due to poor equipment adaptability, the maintenance cost and inspection time cost are high.

[0004] Therefore, a top-driven drainage pipeline inspection device is proposed to solve the above-mentioned problems. An adaptive top-driven carrier equipment is designed to overcome the industry challenge of rapid detection in situations with water or sediment in the pipe, effectively enhancing the equipment's reliability and adaptability to different inspection scenarios. Equipped with a dedicated visual intelligent recognition and laser scanning system for drainage pipes, it can quickly collect and identify defects in the pipeline, perceive the current status of the pipeline from multiple dimensions, and provide reliable data for the three-dimensional visualization and intelligent operation and maintenance management of drainage pipe networks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A top-driven drainage pipe inspection device includes a vehicle body for housing related electrical equipment; the top of the vehicle body is provided with a vehicle body inspection cover for later maintenance. Inspection cameras are installed on both the front and rear sides of the vehicle body for real-time inspection and monitoring. The front and rear sides of the vehicle body are provided with drive stabilization mechanisms, which are used to drive the device to move and prevent the vehicle body from overturning. The vehicle body is equipped with a control mechanism inside, which is used to control the support height of the adjustment equipment; The control mechanism is provided with a support component extending to the outside of the vehicle body to support and guide the equipment. The support assembly is equipped with a telescopic control mechanism to control and adjust the support length to match the inner diameter of the pipe.

[0007] Preferably, the drive stabilization mechanism includes two first hydraulic rods, which are rotatably mounted on the front and rear sides of the vehicle body. A first drive wheel is movably mounted between the output ends of the two first hydraulic rods. A second hydraulic rod is rotatably mounted on the rear side of the vehicle body, and a second drive wheel is movably mounted on the output end of the second hydraulic rod.

[0008] Preferably, the control mechanism includes two first motors, which are fixedly installed inside the vehicle body. Two drive shafts are rotatably installed inside the vehicle body. Bevel gears are fixedly installed on the outer side of the output shaft of the first motor and the drive shaft on one side. Adjacent bevel gears mesh with each other. A protrusion is fixedly installed on the outer side of the drive shaft.

[0009] Preferably, the support assembly includes a connecting block, which is fixedly installed on the outside of the drive shaft and the protrusion. There are four connecting blocks arranged in a rectangular array on the left and right sides of the vehicle body. One end of the connecting block extends to the outside of the vehicle body and is fixedly connected to a support column. An extension column extending to the outside of the support column is movably installed inside the support column. A mounting bracket is fixedly connected to one end of the extension column located outside the support column. A sliding wheel extending to the outside of the mounting bracket is rotatably installed on the inner side of the mounting bracket.

[0010] Preferably, the telescopic control mechanism includes a second motor, which is fixedly installed inside the support column. The output shaft of the second motor is fixedly connected to a lead screw, and a threaded sleeve extending to one end of the lead screw is threaded on its outer side. A telescopic spring is fixedly installed between the threaded sleeve and the extension column.

[0011] Preferably, the left and right sides of the vehicle body are provided with grooves that are adapted to the movement trajectory of the connecting block.

[0012] Preferably, a first guide plate is fixedly installed at one end of the extension column inside the support column, a second guide plate is fixedly installed on the side of the threaded sleeve near the first guide plate, a slide rail that is slidably connected to the first guide plate and the second guide plate is fixedly installed inside the support column, and a small laser scanning device is installed at the top and bottom of the vehicle body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This top-driven drainage pipe inspection equipment significantly improves its adaptability and stability within drainage pipes through the coordinated design of its support components and telescopic control mechanism. The support components connect the vehicle body to the support column via four rectangular arrayed connecting blocks. Combined with the sliding wheels at the ends of the extension columns, the equipment's stress within the pipes is distributed, preventing displacement or jamming caused by single-point load-bearing.

Combined with the elastic buffer of the telescopic spring, the telescopic length of the extension column can be precisely adjusted, ensuring that the sliding wheels fit tightly against the inner walls of pipes with different inner diameters. This effectively enhances the equipment's adaptability to complex pipe environments.

[0014] This top-driven drainage pipe inspection equipment uses a first motor in the control mechanism that drives the transmission shaft through the meshing of a bevel gear and a cam to move the equipment. This, in turn, drives the support column to adjust its angle via a connecting block, ensuring that the bottom of the vehicle body is above the center point of the pipe when the equipment travels in a straight line inside the pipe. The vehicle body inspection cover facilitates the later inspection and maintenance of the electrical equipment inside the vehicle body, while the real-time monitoring function of the inspection camera provides intuitive data support for the efficient detection of the pipe status.

[0021] Example

[0022] like Figs. 1 to 4 As shown, this utility model provides a technical solution: a top-driven drainage pipe inspection device, including a vehicle body 1 for housing related electrical equipment; a vehicle body inspection cover 2 is provided on the top of the vehicle body 1, which facilitates the later inspection and maintenance of the electrical equipment inside the vehicle body 1 and provides wiring ports; the bottom and sides of the vehicle body are sealed, and inspection cameras 3 are provided on both the front and rear sides of the vehicle body 1. The real-time monitoring function of the inspection cameras 3 provides intuitive data support for the efficient detection of pipe status, and has a memory device for recording video.

[0023] A drive stabilization mechanism 4 is provided on the front and rear sides of the vehicle body 1. The drive stabilization mechanism 4 includes two first hydraulic rods 41, which are rotatably mounted on the front and rear sides of the vehicle body 1. A first drive wheel 42 is movably mounted between the output ends of the two first hydraulic rods 41. A second hydraulic rod 43 is rotatably mounted on the rear side of the vehicle body 1. A second drive wheel 44 is movably mounted on the output end of the second hydraulic rod 43. The first drive wheel 42 and the second drive wheel 44 are self-electric driven. When the hydraulic rods are in working state, the first drive wheel 42 can be tightly attached to the pipe wall. When the second hydraulic rod 43 is in working state, the second drive wheel 44 is electrically driven. Wheel 44 can be tightly attached to the pipe wall to prevent the vehicle from tipping over. It is equipped with identical drive wheels at the front and rear. The vehicle can move forward in either rear-wheel drive or all-wheel drive mode. When the vehicle moves forward, the rear drive wheel is engaged, while the front drive wheel coasts or serves as a backup. When the vehicle moves backward, the "rear drive wheel" in the direction of travel remains engaged, while the other drive wheel coasts without power or serves as a backup. It can be manually controlled through the control system and can also be connected to an intelligent driving module to complete autonomous driving and inspection tasks. The drive control system can directly perform distance measurement, record and provide feedback on distance travel, and can be manually corrected. The drive control system adopts technologies known in the prior art.

[0024] The body body 1 is equipped with a control mechanism 5. The control mechanism 5 includes two first motors 51, which are fixedly installed inside the body body 1. Two drive shafts 52 are rotatably installed inside the body body 1. The output shaft of the first motor 51 and the outer side of the drive shaft 52 on one side are both fixedly installed with bevel gears 53. Adjacent bevel gears 53 mesh with each other. The outer side of the drive shaft 52 is fixedly installed with a protrusion 54, which converts the rotational motion of the motor output shaft into the rotational motion of the drive shaft 52.

[0025] A support assembly 6 extending to the outside of the vehicle body 1 is provided on the outer side of the control mechanism 5. The support assembly 6 includes a connecting block 61, which is fixedly installed on the outside of the drive shaft 52 and the protrusion 54. There are four connecting blocks 61, which are distributed in a rectangular array on the left and right sides of the vehicle body 1. Grooves 611 adapted to the movement trajectory of the connecting blocks 61 are provided on both the left and right sides of the vehicle body 1. One end of the connecting block 61 extends to the outside of the vehicle body 1 and is fixedly connected to a support column 62. An extension column 63 extending to the outside of the support column 62 is movably installed inside the support column 62. A first guide is fixedly installed at one end of the extension column 63 inside the support column 62. The extension column 63 is fixedly connected to a mounting bracket 64 at one end outside the support column 62. A sliding wheel 65 extending to the outside of the mounting bracket 64 is rotatably mounted on the inner side of the mounting bracket 64. This top-driven drainage pipe inspection equipment is driven by the first motor 51 in the control mechanism 5 through the meshing of the bevel gear 53 and the transmission shaft 52, and the transmission is carried out in conjunction with the protrusion 54. Then, the support column 62 is driven to adjust the angle through the connecting block 61, so that when the equipment moves in a straight line in the pipe, the bottom of the vehicle body is above the center point of the pipe. The sliding wheel 65 contacts the inner wall of the pipe, assists the movement of the equipment and further disperses the pressure, reducing the friction loss between the equipment and the pipe.

[0026] The support assembly 6 is internally equipped with a telescopic control mechanism 7, which includes a second motor 71. The second motor 71 is fixedly installed inside the support column 62. The output shaft of the second motor 71 is fixedly connected to a lead screw 72. A threaded sleeve 73 extending to one end of the lead screw 72 is threadedly installed on the outer side of the lead screw 72. A second guide plate 731 is fixedly installed on the side of the threaded sleeve 73 near the first guide plate 631. A slide rail 732 is fixedly installed inside the support column 62 and is slidably connected to the first guide plate 631 and the second guide plate 731. The slide rail 732 provides sliding constraints for the first guide plate 631 and the second guide plate 731, ensuring that the extension column 63 and the threaded sleeve 73 can only move linearly along the axial direction of the lead screw 72, avoiding structural jamming or failure due to multi-directional forces, and improving the working stability of the telescopic control mechanism 7.

[0027] A telescopic spring 74 is fixedly installed between the threaded sleeve 73 and the extension column 63. This top-driven drainage pipe inspection equipment significantly improves the adaptability and stability of the equipment in the drainage pipe through the coordinated design of the support component 6 and the telescopic control mechanism 7. The support component 6 connects the vehicle body 1 and the support column 62 through four rectangular array connecting blocks 61. With the help of the sliding wheel 65 at the end of the extension column 63, the force on the equipment in the pipe can be distributed to avoid displacement or jamming caused by single-point load. The telescopic control mechanism 7 drives the lead screw 72 to rotate through the second motor 71, which drives the threaded sleeve 73 to move axially. Combined with the elastic buffer of the telescopic spring 74, the telescopic length of the extension column 63 can be precisely adjusted so that the sliding wheel 65 fits tightly against the inner wall of pipes with different inner diameters. This effectively enhances the adaptability of the equipment to complex pipe environments. Small laser scanning devices are installed on the top and bottom of the vehicle body. The equipment can collect point cloud data of the pipe in real time during the inspection. After acquiring the data, the condition of the inner wall of the pipe can be reconstructed in three dimensions.

[0028] The working process of this utility model: Step 1: After the equipment enters the drainage pipe, the control mechanism 5 is activated. The first motor 51 drives the bevel gear 53 fixed to it to rotate through the output shaft. It meshes with the bevel gear 53 on the outside of the transmission shaft 52, driving the transmission shaft 52 to rotate synchronously. This pushes or pulls the connecting block 61 to move along the groove 611 on one side of the vehicle body 1, adjusting the tilt angle and position of the support column 62 so that the support assembly 6 adapts to the initial environment inside the pipe. Step 2: The second motor 71 of the telescopic control mechanism 7 is started, driving the lead screw 72 to rotate. The threaded sleeve 73 moves along its axial direction due to its threaded connection with the lead screw 72. Through the sliding cooperation between the second guide plate 731 and the slide rail 732, the extension column 63 is pushed or pulled to extend or retract from the support column 62. At the same time, the first guide plate 631 moves synchronously with the extension column 63 and slides with the slide rail 732 to ensure that the extension column 63 extends and retracts linearly until the sliding wheel 65 contacts the inner wall of the pipe and applies a supporting force, thus completing the support and positioning of the equipment in the pipe. Step 3: The first hydraulic rod 41 and the second hydraulic rod 43 of the driving stabilizing mechanism 4 drive the first drive wheel 42 and the second drive wheel 44 to extend and retract respectively. The first drive wheel 42 provides the power for the equipment to move forward (using a self-powered electric drive method), and the second drive wheel 44 contacts the inner wall of the pipeline to prevent the vehicle from tipping over and ensure stable movement of the equipment. During the inspection, the inspection camera 3 at the bottom of the vehicle body 1 collects and transmits images of the inside of the pipeline in real time. After processing, the images are fed back to the external terminal to realize real-time monitoring of the pipeline status. If it is necessary to adjust the support length or angle, the control mechanism 5 and the extension control mechanism 7 repeat the above actions until the entire pipeline inspection task is completed.
