Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, and more specifically, to a portable lighting device for pipeline inspection. Background Technology

[0002] In existing pipeline internal inspection technologies, portable lighting devices are commonly used in conjunction with cameras for observation. However, traditional equipment has significant technical limitations. On the one hand, lighting systems often use ordinary reflective structures or fixed light source designs. The bulb installation position is difficult to precisely maintain on the focal point of the condenser lens, and it is prone to displacement during transportation or use, resulting in ineffective light convergence, beam divergence, low central illumination, and short illumination distance, severely affecting the visibility clarity deep within the pipeline. On the other hand, the camera unit is usually rigidly connected to the lighting module, lacking a flexible angle adjustment mechanism. It cannot adjust the shooting angle in real time according to the pipeline direction or inspection requirements, resulting in a large number of blind spots on the inner wall. At the same time, existing devices have low integration, with independent control of the lighting and imaging systems, making operation cumbersome, portability poor, and difficult to achieve efficient single-person operation. Utility Model Content

[0003] The purpose of this invention is to provide a portable lighting device for pipeline inspection to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a portable lighting device for pipeline inspection, comprising a first housing, a condenser lens fixedly connected to one side of the first housing for concentrating and directionally projecting a light source to improve the brightness and visibility distance inside the pipeline, a second connecting plate fixedly connected to the inner wall of the first housing, a slider fixedly connected to the lower end of the second connecting plate, a slide rail slidably connected to the lower end of the slider, a third connecting plate fixedly connected to one side of the second connecting plate, a pneumatic rod fixedly connected to one side of the third connecting plate, the pneumatic rod being connected to the output end of a pneumatic cylinder, and a fourth fixing plate fixedly connected to the outer wall of the pneumatic cylinder.

[0008] As a preferred embodiment of this utility model, one end of the first rotating shaft is fixedly connected to a first gear, the first gear meshes with a second gear, and the inner wall of the second gear is fixedly connected to a second rotating shaft.

[0009] As a preferred technical solution of this utility model, one side of the second rotating shaft is rotatably connected to the first support plate through a sliding bearing, the other end of the second rotating shaft is fixedly connected to the first connecting plate, and a camera is fixedly connected to one side of the first connecting plate for collecting images inside the pipe, which, combined with the lighting system, enables all-round, adjustable visual detection.

[0010] As a preferred technical solution of this utility model, the condenser lens is a parabolic concave surface, which has good light converging performance and can reflect the light emitted by the bulb into a parallel beam, thereby enhancing the illumination distance and center brightness.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) In this device, a parabolic concave condenser lens and a bulb work together. The bulb is located at the focal point of the condenser lens. When the bulb emits light, the light is refracted by the parabolic surface to form an approximately parallel beam that is projected forward. At the same time, the pneumatic cylinder drives the third connecting plate, the second connecting plate and the slider to move parallel along the slide rail by pushing the pneumatic rod, thereby adjusting the accuracy of the bulb at the focal point of the condenser lens, achieving the best focusing effect, effectively enhancing the center brightness and illumination distance, and overcoming the problem of poor focusing effect caused by position deviation of traditional fixed light sources.

[0012] (2) In this device, the first motor drives the first rotating shaft to rotate, which in turn drives the first gear to rotate. Through meshing with the second gear, the second rotating shaft and the first connecting plate fixedly connected to it rotate, thereby realizing the tilt adjustment of the camera. With the help of adjustable lighting, it can capture images of the inner wall of the pipeline in a comprehensive manner and avoid blind spots in the detection. The operator can hold the device by the handle, which makes it easy to move and position flexibly in complex pipeline environments, truly realizing portable, efficient and visualized pipeline internal detection.
