    摘要： The present application relates to a pipe cleaner and a pipeline cleaning system, the pipe cleaner is applied to a to-be-cleaned pipeline, the pipe cleaner comprises a body (100), and a cleaning portion (110) is arranged on the surface of the body; wherein the cleaning portion is configured as a conductive structure, and when the body moves along the pipeline (200), the cleaning portion can push out dust particles in the pipeline to the tail end of the pipeline and guide out static electricity generated by friction with the pipeline. In the present application, by arranging the cleaning portion arranged on the surface of the pipe cleaner body as a conductive structure, it is feasible to utilize the conductivity of the cleaning portion to effectively guide out the static electricity generated by friction between the cleaning portion and the pipe wall through the pipeline during the process of cleaning dust particles in the pipeline with the pipe cleaner, and effectively prevent the static electricity from being accumulated at the cleaning portion and the surface of the pipe cleaner and reacting with hazardous dust particles, thereby not only ensuring the cleaning effect for the pipeline, but also ensuring safety in the process of cleaning dust particles in the pipeline with a pipe cleaner, and safety accidents such as combustion and explosion are avoided.

    摘要： A protection device, a dust removal device, a wheel rim structure and an automobile. The protection device comprises a first protection structure (1), a second protection structure (2) and a guide structure (3). The first protection structure (1) comprises first blades (11) and a first rotating ring (12), and one end of each first blade (11) is connected to the first rotating ring (12). The second protection structure (2) comprises second blades (21) and a second rotating ring (22), and one end of each second blade (21) is connected to the second rotating ring (22). The first rotating ring (12) is sleeved outside the second rotating ring (22). The guide structure (3) is arranged between the first rotating ring (12) and the second rotating ring (22). The first rotating ring (12) can rotate relative to the second rotating ring (22), so that the first blades (11) and the second blades (21) overlap or are staggered. The guide structure (3) is used for limiting the rotation travel of the first rotating ring (12) relative to the second rotating ring (22). The protection device is simple in terms of structure, and is automatically turned on according to inertia generated by means of braking, thus preventing a vehicle from the adhesion or collection of non-brake dust, such as wheel-edge dust, when the vehicle does not brake. A purely mechanical structure is used, and no additional energy is consumed.

    摘要： One embodiment is a combined welder and fume extractor system (100, 200, 400, 600) having a chassis assembly (601) along with a controller (140, 240, 500, 605) and a user interface which are substantially within the chassis assembly (601) to control operation of the system (100, 200, 400, 600) and allow a user to interact with the system (100, 200, 400, 600). A filter compartment (650) within the chassis assembly (601) has at least one filter (655) to extract welding fume particles from a stream of air (657) forced through the filter compartment (650). An extractor compartment (640) within the chassis assembly (601) has at least one fan (130, 230, 645) to force the stream of air (657) through the filter compartment (650). A welding power source compartment (270, 620) within the chassis assembly (601) has welding power electronics circuitry (625) to generate welding output power for a welding operation. A wire feeder compartment (630) within the chassis assembly (601) has a spool (634) of a welding wire electrode (636) and a wire feeder (632) to feed the welding wire electrode (636) from the spool (634).
