Inspection device and inspection method

Abstract

An inspection device (10) for inspecting a gas pipeline on a wall (20) by using an inspection method, comprising: an inspection unit (100) movable along two guide cables (210) extending across upper and lower positions . The inspection unit includes: a camera (410), a transmitter (430) for captured images, and a gas detector (420) for detecting gas leaks. The gas detector has a detector body (422) connected by a probe (423) which can be extended outwardly for operation close to the gas pipeline. The inspection method comprises: connecting a weight (220) to the cable at an upper position, then lowering the cable together with the weight until the weight reaches or at least partially rests on the lower position, so as to be guided by keeping the cable taut Check unit. After use, the cable with the weight will be moved from the lower position back to the upper position.

Description

technical field [0001] The present invention relates to an inspection device and an inspection method, especially for inspecting gas pipelines for maintenance and / or checking gas pipeline leakage, but not limited thereto. Background technique [0002] Fixtures such as gas pipes or fixtures mounted on high walls, especially on the walls or sides of buildings, can be difficult to inspect for failure or damage, or for routine maintenance purposes . [0003] If a window on an adjacent floor is close to a wall or building-mounted gas line, the gas line can be accessed from that window, or alternatively, can be lowered from the roof by remaining in a suspended platform or hanger, which would otherwise require a to scaffolding, but all of these methods are flawed in terms of preparation and time, and especially when it comes to workplace safety. [0004] The present invention seeks to eliminate or at least alleviate such problems by providing a completely new or otherwise improve...
