This invention discloses a non-contact ship bottom cleaning machine based on pulse cavitation technology, comprising a mounting frame with a sealed box, inside which are pulse cavitation generation equipment and control equipment. Two drive wheels are fitted with transmission belts, the outer walls of which are fixed with permanent magnets. A drive mechanism for rotating a drive shaft is installed inside the sealed box. A mounting plate is mounted on the mounting frame, and multiple sets of dirt guiding mechanisms are installed on the mounting plate. This invention effectively solves the core technical bottlenecks of existing pulse cavitation cleaning robots, achieving integrated operation of non-contact, high-efficiency ship bottom cleaning and simultaneous dirt collection. It retains the advantages of pulse cavitation technology—high cleaning efficiency, no secondary damage, and environmental friendliness—while avoiding the impact of dirt diffusion on the moving mechanism, thus improving the machine's mobility and operational stability.

This application discloses an overhead crossbeam device, comprising: an anchor, which is anchored in a drilled hole in the tunnel wall; a support member, which is fixed to the anchor and has its top surface forming a crossbeam support surface; and a fastener, which is bolted to the support member and cooperates with the support member to clamp the crossbeam. The modular components achieve reliable fixation of the crossbeam, solving the problems of easy loosening and difficult disassembly of crossbeams in traditional installations. It also provides a structural foundation for subsequent adjustment and maintenance, expanding its applicability to various tunnel environments.
