Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology for water networks, specifically an improved pipeline inspection device for water networks. Background Technology

[0002] The water network pipeline inspection device is a specialized piece of equipment that can enter the inside of pipelines and replace manual inspection to detect the location of pipeline damage and blockages.

[0003] Existing pipeline inspection devices typically employ traditional wheel sets or track drives. The drive motors are mostly fixed directly near the axle or integrated with the wheel body, achieving basic movements like forward, backward, and turning through simple differential steering or track flexibility. This traditional drive and layout method is problematic because pipelines often have narrow spaces and complex environments, frequently containing silt, water, and obstacles. The directly exposed drive motors are highly susceptible to sewage and sediment intrusion, leading to short circuits, corrosion, or torque reduction, significantly impacting reliability and lifespan. Furthermore, the limited movement of ordinary wheels or tracks, lacking lateral mobility, often requires multiple forward and backward maneuvers and adjustments to pass through narrow bends, T-junctions, or complex obstructions within the pipeline. This inconvenience and poor maneuverability, and even the risk of jamming or getting trapped, severely impacts the efficiency and success rate of inspection operations. Utility Model Content

[0004] The purpose of this invention is to provide an improved pipeline inspection device for water networks, which solves the problem of mobility and reliability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an improved pipe inspection device for water networks, including Mecanum wheels. Six Mecanum wheels are symmetrically arranged on both sides of the device. Each Mecanum wheel is driven by a drive motor, and each drive motor is enclosed in an independent storage box. The side wall of the storage box is provided with a connection hole for the drive shaft of the drive motor to pass through. The rear end of the storage box is provided with a wire outlet hole, which is connected to a wire conduit. All the wire conduits extend rearward and are connected to a power control component located at the rear of the device.

[0007] Furthermore, the Mecanum wheel includes a wheel body, on the outer circumference of which are symmetrically arranged fixed plates. Rollers are mounted between adjacent fixed plates via fixed shafts, and the roller direction of the Mecanum wheel located on the left side of the device is opposite to that of the Mecanum wheel located on the right side.

[0008] Furthermore, the device has a positioning camera assembly at its front end center. The positioning camera assembly includes a high-definition camera. The front lens of the high-definition camera is coated with a superhydrophobic coating. Its rear end is connected to an up-down motion pair and a left-right motion pair in sequence. The rear end of the left-right motion pair is connected to a motion shaft.

[0009] Furthermore, the lower end of the high-definition camera is connected to a magnetic ball via a connecting rod. The magnetic ball is placed on a fixed platform with a circular groove in the center. Around the platform, there are eight energized strong magnets corresponding to the magnetic ball, and each energized strong magnet has an insulating ring around its outer ring.

[0010] Furthermore, the device is also equipped with an auxiliary lifting assembly, which includes a lifting cylinder. The lower end of the lifting cylinder is connected to a cylinder push rod, and the end of the cylinder push rod is connected to a lifting auxiliary wheel.

[0011] Furthermore, four lighting components are symmetrically arranged on the left and right sides of the front end of the device. The lighting components include searchlights, which are connected to the power control component through searchlight transmission pipes. A camera light is also provided above the high-definition camera of the device.

[0012] Furthermore, the power control assembly includes a control element center and a power center, wherein the control element center is connected to the power center via a transmission tube.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model uses a Mecanum wheel as the core walking mechanism. The freely rolling rollers symmetrically installed on the rim of the wheel at a specific angle can generate multidimensional friction when in contact with the inner wall of the pipe. By controlling the rotation speed and steering combination of the Mecanum wheels on the left and right sides (the rollers are tilted in opposite directions), the device can finally achieve omnidirectional flexible movement in the pipe, including forward, backward, lateral, oblique, and even stationary rotation. This avoids the mobility problems of traditional pipe inspection equipment, such as clumsy steering, multiple adjustments to pass, or even jamming, in complex parts such as bends and interfaces.

[0015] (2) This utility model achieves a wide range of adjustment of the basic orientation of the high-definition camera by cooperating the up-down kinematic pairs and the left-right kinematic pairs along the motion axis. At the same time, by controlling the magnetic attraction of the magnetic ball by the energized strong magnets of the circumferential array and transmitting micro-motion through the connecting rod, the camera angle is finely adjusted. This combination of macroscopic kinematic pairs and microscopic magnetic control achieves multi-degree-of-freedom, non-contact, and precise positioning. The application of the superhydrophobic coating on the lens avoids the problem of blurred vision caused by water droplets, and the insulating ring avoids mutual interference of the magnetic fields between multiple energized strong magnets. Together, these solve the problems of inconvenient adjustment, unclear vision, and inaccurate positioning of traditional cameras in pipes.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] Please see Figures 1-7 As shown, this utility model is an improved pipe inspection device for water networks, including Mecanum wheels 1. Six Mecanum wheels 1 are symmetrically arranged on both sides of the device. Each Mecanum wheel 1 is driven by a drive motor 11, and each drive motor 11 is enclosed in an independent storage box 6. The side wall of the storage box 6 is provided with a connection hole 61 for the drive shaft 12 of the drive motor 11 to pass through. The rear end of the storage box 6 is provided with a wire outlet hole 62, which is connected to a wire conduit 63. All wire conduits 63 extend rearward and are connected to a power control component 4 located at the rear of the device.

[0029] The Mecanum wheel 1 includes a wheel body, on the outer circumference of which there are symmetrical fixed plates 14 arranged in a circular array. Rollers 13 are mounted between adjacent fixed plates 14 via fixed shafts 15. The direction of the roller 13 of the Mecanum wheel 1 on the left side of the device is opposite to that of the roller 13 of the Mecanum wheel 1 on the right side.

[0030] The power control component 4 distributes power, and the electrical energy is introduced into each independent storage box 6 through the wire conduit 63 via the outlet hole 62 at the rear end of the storage box 6, driving the drive motor 11 sealed inside to operate. The torque generated by the drive motor 11 is output through the drive shaft 12, which extends through the connection hole 61 on the side wall of the storage box 6, thereby driving the Mecanum wheel 1 to rotate. When the wheel rotates, the fixed plates 14 symmetrically arranged on its outer circumference move accordingly. The rollers 13 installed between the fixed plates 14 through the fixed shaft 15 come into contact with the inner wall of the pipe and roll. Since the rollers 13 on the left and right sides of the Mecanum wheel 1 are tilted in opposite directions, the resultant force generated by the friction between each group of rollers 13 and the pipe wall finally realizes the flexible omnidirectional movement of the device. This structure significantly improves the reliability and environmental adaptability of the drive system by independently sealing and protecting the drive motor 11 and centrally wiring it with the rear power supply. At the same time, the special configuration of the Mecanum wheel 1 greatly enhances the mobility of the device in the pipe.

[0031] The device has a positioning camera assembly 2 at the front center. The positioning camera assembly 2 includes a high-definition camera. The front lens of the high-definition camera is provided with a superhydrophobic coating 22. Its rear end is connected to an up-down motion pair 27 and a left-right motion pair 28 in sequence. The rear end of the left-right motion pair 28 is connected to a motion shaft 29.

[0032] The lower end of the high-definition camera is connected to a magnetic ball 24 via a connecting rod 23. The magnetic ball 24 is placed on a fixed platform with a circular groove in the center. Around the platform, there are eight energized strong magnets 25 corresponding to the magnetic ball 24. Each energized strong magnet 25 has an insulating ring 26 on its outer ring.

[0033] Among them, the high-definition camera is a kind of camera tool, please refer to the patent number "CN105577995A A High-Definition Camera" for details;

[0034] When the positioning camera assembly 2 is in operation, the high-definition camera performs basic large-angle orientation adjustment along the motion axis 29 through the up-down motion joint 27 and the left-right motion joint 28 connected to its rear end. At the same time, by controlling the energization state of the eight energized strong magnets 25 in the circumferential array around the control surface, they generate a controllable magnetic attraction to the magnetic ball 24 placed in the central groove. The magnetic ball 24 undergoes a slight displacement under the attraction, thereby applying a precise push or pull force to the high-definition camera through the connecting rod 23 connected to it, achieving fine-tuning of the viewing angle. During the entire adjustment process, the superhydrophobic coating 22 of the front lens of the high-definition camera can effectively repel water droplets and maintain a clear field of view, while the insulating ring 26 on the outer ring of each energized strong magnet 25 ensures that their magnetic forces do not interfere with each other or affect surrounding components. The multi-degree-of-freedom precise and stable adjustment of the camera's macro orientation and micro angle significantly improves the ability to obtain clear and comprehensive visual information in complex pipe environments.

[0035] The device is also equipped with an auxiliary lifting component 3, which includes a lifting cylinder 31. The lower end of the lifting cylinder 31 is connected to a cylinder push rod 32, and the end of the cylinder push rod 32 is connected to a lifting auxiliary wheel 33.

[0036] When the auxiliary lifting component 3 is working, the lifting cylinder 31 serves as the power source, driving the cylinder push rod 32 at its lower end to extend and retract. When an obstacle is encountered in the pipeline or the vehicle body posture needs to be adjusted, the cylinder push rod 32 extends downward, pushing the lifting auxiliary wheel 33 at its end to contact the inner wall of the pipeline, thereby lifting the front or middle part of the main body of the device to cross the obstacle or prevent bottoming out. By controlling the action of the lifting cylinder 31, the extension height and support force of the lifting auxiliary wheel 33 can be flexibly controlled. This design provides effective auxiliary support and obstacle crossing ability, enhancing its passability and reliability.

[0037] Four lighting components 5 are symmetrically arranged on the left and right sides of the front end of the device. The lighting components 5 include searchlights 51. The searchlights 51 are connected to the power control component 4 through the searchlight transmission pipe 52. A camera light 21 is also provided above the high-definition camera of the device.

[0038] Among them, the searchlight 51 is a search tool, please refer to the patent number "CN117053163A A searchlight" for details;

[0039] When the lighting system is in operation, the power supplied by the power control component 4 is transmitted through the searchlight transmission pipe 52 to the four searchlights 51 symmetrically arranged on the left and right sides of the front end of the device, so that they emit a wide beam of light to provide basic lighting for a large area in front of the pipe. At the same time, the camera light 21 set above the high-definition camera is lit up simultaneously to provide targeted supplementary lighting for the camera's close-range observation targets. By combining basic lighting with targeted supplementary lighting, visual blind spots and shadows inside the pipe are effectively eliminated, ensuring the clarity and reliability of image acquisition.

[0040] The power control assembly 4 includes a control element center 41 and a power center 43. The control element center 41 is connected to the power center 43 through a transmission pipe 42.

[0041] When the power control component 4 is working, the control element center 41 serves as the control core of the entire device. It receives external commands and sends control signals. These signals are transmitted to the power center 43 through the transmission tube 42, which directs it to perform precise power distribution and management, thereby coordinating the stable and collaborative operation of all functional modules such as drive, lighting, and camera.

[0042] In use, the movement of the device begins with an operation command transmitted to the control element center 41 of the power control component 4. The latter coordinates the power distribution of the power center 43 through the transmission pipe 42. The power is transmitted through the conductor pipe 63 and enters the box through the outlet hole 62 on the rear wall of the storage box 6, supplying the various drive motors 11 sealed in the storage box 6. The torque generated by the drive motor 11 is output through the drive shaft 12, which extends through the connection hole 61 on the side wall of the storage box 6, thereby driving the Mecanum wheel 1 to rotate. The combined friction between the rollers 13 arranged in a specific direction on the Mecanum wheel 1 and mounted on the fixed plate 14 through the fixed shaft 15 and the pipe wall ultimately realizes the omnidirectional movement of the device. When passing through complex road sections, the lifting cylinder 31 of the auxiliary lifting component 3 pushes... The cylinder push rod 32 extends the lifting auxiliary wheel 33 to adjust the vehicle's posture. At the same time, the spotlight 51 of the lighting assembly 5 is powered by the spotlight transmission pipe 52 to illuminate the front. The lens of the positioning camera assembly 2 has a superhydrophobic coating 22 to ensure a clear field of view. The energized strong magnet 25 causes the magnetic ball 24 to move under magnetic attraction and shift its position through the recess at its lower end. The connecting rod 23 connected to the magnetic ball 24 pushes the camera's viewing angle for fine adjustment. The energized strong magnet 25 connected to it has an insulating ring 26 to isolate the magnetic force from the surrounding environment. The up-down motion pair 27 and the left-right motion pair 28 adjust the basic orientation of the high-definition camera along the motion axis 29 with the magnetic shift at the lower end. The camera spotlight 21 on top of it follows the movement of the camera to provide supplementary lighting, thereby completing the entire inspection operation.
