Abstract: A playbook execution architecture used to efficiently execute playbooks by distributing the execution of playbook function blocks to multiple independent “worker” sub-processes is described. Each worker process hosts an independent execution environment used to execute playbook function blocks independently from other worker processes, where each worker process can host an execution environment that is the same as or different from execution environments hosted by other work processes, enabling the playbook execution engine to support function blocks written in multiple different programming language versions or programming languages entirely.

Abstract: A self-locking water level adjusting mechanism includes a partition plate, an adjusting clamping structure arranged on one side of the partition plate, and an adjusting lock. The adjusting clamping structure is slidably connected with the partition plate in a vertical direction. The adjusting lock is elastically connected with the partition plate through an elastic piece. The adjusting lock is clamped with the adjusting clamping structure under restoring force of the elastic piece.
