Abstract
Description
Technical Field
[0001] This application relates to the field of pipeline inspection technology, and in particular to an integrated non-powered drifting encapsulation structure. Background Technology
[0002] With the development of urban construction and production, the scale of underground drainage pipe networks is expanding daily, making routine maintenance and inspection particularly important. Underground drainage pipe networks are complex and large-scale, and during use, more and more problems are being exposed, such as mixed rainwater and sewage connections, pipe deformation, siltation, and damage—functional and structural defects that seriously affect the normal operation of the drainage network. A common method for inspecting the operation of underground drainage pipes is manual entry into the pipes; however, the high water level and fast flow velocity within the drainage network make manual entry for maintenance work quite dangerous.
[0003] Therefore, capsule robots are currently used to replace manual labor in inspecting drainage pipe networks. These robots drift within the network and record drainage conditions using cameras, significantly improving inspection efficiency. However, current capsule robots are susceptible to capsizing due to water flow fluctuations or collisions caused by water current disturbances, resulting in structural damage. Furthermore, the cameras and control mechanisms are prone to water ingress, increasing maintenance costs and reducing the efficiency of drainage pipe network inspections. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides an integrated, non-powered drifting packaging structure.
[0005] This application provides an integrated, non-powered drifting packaging structure, which adopts the following technical solution:
[0006] An integrated, non-powered drifting encapsulation structure includes a housing, a turntable mechanism disposed within the inner cavity of the housing, a camera mechanism connected to the turntable mechanism, a transparent cover for protecting the camera mechanism, a floating layer disposed at the bottom of the inner cavity of the housing, and a mounting base plate. The top of the housing has a mounting through-hole, the transparent cover is disposed within the mounting through-hole, the turntable mechanism is used to adjust the angle of the camera mechanism, the turntable mechanism includes a horizontal rotation component and a vertical rotation component, a buffer cavity is disposed in the center of the floating layer, the mounting base plate is disposed in the buffer cavity and connected to the floating layer, the turntable mechanism is disposed in the center of the mounting base plate, and a battery is disposed in the buffer cavity, the battery being electrically connected to the camera mechanism and the turntable mechanism.
[0007] By adopting the above technical solutions, the pipeline inspection capsule robot achieves stable floating and efficient inspection in complex water flow environments. A mounting hole on the top of the outer shell, along with a transparent cover, protects the camera mechanism from water flow. A buffer cavity is located in the center of the floating layer, housing the mounting base plate and creating a stable center of gravity distribution. This enhances the device's resistance to bumps and reduces the risk of structural damage caused by water flow impact. The turntable mechanism includes horizontal and vertical rotation components, allowing for flexible adjustment of the camera angle and significantly improving image capture range and quality, providing more effective information for subsequent data analysis. During rotation, the center of gravity remains in the center of the pipeline inspection capsule robot structure, ensuring stability under the influence of gravity and enabling normal drifting in turbulent water. The buffer cavity houses a battery, optimizing space layout while ensuring power supply, supporting the coordinated operation of various functional modules, extending the device's battery life, and improving work efficiency.
[0008] Preferably, the outer shell has a triangular structure, the front end of the outer shell has an arc-shaped pointed structure, and the rear end of the outer shell has a planar structure.
[0009] By adopting the above technical solutions, the triangular shell design effectively reduces water flow resistance, allowing the capsule robot to drift more smoothly within the pipe. The arc-shaped tip structure further optimizes the streamlined design, helping to guide a smooth transition in water flow and reducing the risk of capsizing. The planar rear end enhances overall stability, preventing loss of attitude due to water flow impact, thereby improving the device's self-stabilizing ability in complex water flow environments.
[0010] Preferably, the top surface of the outer shell has arc-shaped pressure-reducing grooves on both sides.
[0011] By adopting the above technical solution, the arc-shaped pressure-reducing grooves are set on both sides of the top surface of the shell, which can effectively reduce the pressure of water flow on the top of the shell during the capsule robot's drifting process, reduce the instability caused by water flow impact, and improve the stability of the equipment in complex water flow environments.
[0012] Preferably, the transparent cover has an arc-shaped structure.
[0013] By adopting the above technical solution, the arc-shaped transparent cover can effectively guide water droplets to slide off its surface, preventing water droplets from remaining within the camera's field of view, thus ensuring that image clarity is not affected by external factors. This design significantly improves diagnostic accuracy, reduces the possibility of misjudgment caused by water droplet obstruction, and provides the camera with a wider pitch and rotation field of view, further enhancing the quality and coverage of image capture.
[0014] Preferably, the mounting base plate is provided with a reinforcing bracket, which includes multiple first reinforcing rods and multiple second reinforcing rods. One end of the first reinforcing rod extends toward the center of the mounting base plate, and the other end extends away from the center of the mounting base plate. The second reinforcing rod is disposed on the side of the mounting base plate near the arc-shaped tip structure, and the second reinforcing rod is used to connect adjacent first reinforcing rods.
[0015] By adopting the above technical solution, the reinforced bracket on the mounting base significantly enhances the structural strength of the entire device. Specifically, multiple first reinforcing rods are radially distributed, effectively dispersing the stress acting on the mounting base and preventing damage caused by excessive local stress. Second reinforcing rods further connect to adjacent first reinforcing rods at the front end, forming a grid-like support structure at the front, giving the pipeline inspection capsule robot's front end higher structural strength and stronger impact resistance. This makes the overall structure more stable and reliable, enabling it to resist impacts and vibrations in complex water flow environments, reducing the probability of equipment damage caused by bumps, thereby extending the equipment's service life and reducing maintenance costs.
[0016] Preferably, the horizontal rotation assembly includes a mounting tube disposed on the mounting base plate, a first motor disposed in the mounting tube, and a rotating connecting plate. The drive shaft of the first motor is fixedly connected to the rotating connecting plate, and the rotating connecting plate is rotatably connected to the mounting tube. The vertical rotation assembly is disposed on the rotating connecting plate, and the rotation direction of the vertical rotation assembly is perpendicular to that of the horizontal rotation assembly.
[0017] By employing the aforementioned technical solution, the horizontal and vertical rotation components work together to achieve flexible adjustment of the camera mechanism in both horizontal and vertical directions. This dual-axis linkage design significantly enhances the camera's field of view, enabling it to comprehensively capture image information in complex pipeline environments and providing richer data support for subsequent analysis. Simultaneously, this design helps reduce blind spots and improve detection coverage and accuracy.
[0018] Preferably, the vertical rotation assembly includes two connecting pipes respectively disposed on both sides of the rotating connecting plate, a second motor, a connecting plate, a rotating pipe disposed between the two connecting pipes, and connecting shafts disposed at both ends of the rotating pipe. The second motor is disposed in one of the connecting pipes, the connecting plate is disposed in the other connecting pipe, the drive shaft of the second motor is fixedly connected to one of the connecting shafts, and the connecting plate is rotatably connected to the other connecting shaft.
[0019] By adopting the above technical solution, the vertical rotation component enables precise rotation of the camera module in the vertical direction. The second motor drives the connecting shaft to rotate the rotating tube, thereby adjusting the camera's pitch angle. This allows the capsule robot to flexibly adjust its shooting perspective in complex water flow environments, significantly improving the quality and coverage of image capture. The compact and reasonable structural design ensures the overall stability and reliability of the equipment, providing more comprehensive and accurate support for subsequent data analysis.
[0020] Preferably, the camera mechanism includes a camera mounted on a rotating tube and a plurality of fill lights distributed outside the camera, wherein both the camera and the fill lights are electrically connected to the battery.
[0021] By adopting the above technical solution, the camera is mounted on a rotating tube and equipped with multiple supplementary lights distributed around its exterior. This provides ample illumination in low-light or complex pipe environments, ensuring clear and visible images. Simultaneously, the camera's electrical connection to the battery guarantees its power supply, while the distributed design of the supplementary lights further enhances the uniformity of illumination, thereby improving image quality and providing more accurate data support for subsequent analysis.
[0022] Preferably, the front and rear ends of the outer casing are provided with traction holes, which are used to connect traction ropes.
[0023] By adopting the above technical solution, traction holes are opened at both the front and rear ends of the outer shell, allowing the pipeline inspection capsule robot to be pulled forward and backward in both directions using a traction rope. This design not only effectively prevents the equipment from being lost in complex water flow environments, but also increases operational flexibility, facilitating the selection of appropriate traction methods according to different inspection needs, thereby improving the safety and controllability of the pipeline inspection process.
[0024] Preferably, a power indicator light and a power button are provided at the top rear end of the housing, and both the power indicator light and the power button are electrically connected to the battery.
[0025] By adopting the above technical solution, the power indicator light and power button allow users to intuitively understand the power status of the capsule robot and easily switch it on and off. This design improves the ease of operation and helps users promptly detect low power levels, preventing problems such as device malfunction or data loss due to sudden power outages.
[0026] In summary, this application has the following beneficial technical effects:
[0027] 1. The turntable mechanism, through the cooperation of horizontal and vertical rotating components, can precisely adjust the angle of the camera mechanism, enabling the camera to flexibly adjust its viewing angle, greatly improving the quality and coverage of image capture, and providing more comprehensive support for subsequent data analysis;
[0028] 2. The outer shell adopts a triangular structure design with an arc-shaped tip at the front end, which helps to reduce water flow resistance and guide the drift direction. Combined with the design of the floating layer and its buffer chamber, it enhances the stability and impact resistance of the equipment in complex water flow environments and reduces the risk of equipment damage caused by bumps.
[0029] 3. The transparent cover adopts an arc-shaped structure, which not only protects the camera mechanism from direct impact from water, but also effectively prevents water droplets from obstructing the lens, ensuring image clarity and thus improving the accuracy and reliability of the test results.
