This utility model discloses a low-noise electric lawnmower, relating to the field of lawnmower technology. It includes a frame with a U-shaped structure and a drive assembly at the bottom. A motor is mounted inside the frame, moving vertically, and a mowing assembly is fixedly mounted on the motor's output shaft. The mowing assembly includes a fixed cover, an adjusting post, and mowing blades. The upper surface of the fixed cover is fixedly connected to the motor's output shaft, and the adjusting post is fixedly mounted at the bottom. Three mowing blades are slidably mounted on the bottom side of the adjusting post. This utility model utilizes a rotating shaft, worm gear, worm, and adjusting disc. Rotating the adjusting disc drives the rotating disc via the worm gear, causing the connecting rod to slide along the guide groove, simultaneously adjusting the spacing between the three sets of mowing blades. This allows for free adjustment of the mowing range, enabling efficient handling of large lawns while precisely trimming corner areas, reducing repetitive trimming, optimizing the work path, and achieving energy-efficient and intelligent lawn maintenance.

The application relates to the technical field of downhole intelligent setting ball technology, and discloses a downhole intelligent setting ball, which comprises a shell, a piston assembly which is slidably arranged in the shell, a hydraulic chamber which is formed between the piston assembly and the shell, a communication channel which is arranged in the piston assembly and is used for communicating with the inside of a tubing and the hydraulic chamber respectively, a setting assembly which is connected to the piston assembly, and an intelligent on-off control assembly which is arranged in the piston assembly and is used for turning on the communication channel when the shell reaches a predetermined position in a well, so that high-pressure medium in the tubing enters the hydraulic chamber and drives the piston assembly to slide, thereby driving the setting assembly to radially expand and block the inside passage of the tubing. The downhole intelligent setting ball is free from the restriction of a wired carrier on the flexibility of tool movement, and meanwhile, the problem of signal attenuation and measurement error caused by complex working conditions in a well during wired transmission is avoided.

This invention relates to the field of engineering machinery control technology and discloses a method for controlling the movement of counterweights in lifting equipment. The method includes establishing a multi-source heterogeneous data stream, simultaneously acquiring macroscopic operating status data of the lifting equipment and internal stress data of the slewing bearing, reconstructing the load field using the stress data and inverting the actual support reaction moment vector, and simultaneously constructing a virtual rigid body equilibrium model based on the macroscopic data to calculate the theoretical overturning moment vector. By calculating the vector deviation between the two, the structural stiffness factor characterizing the equipment's deformation resistance and the foundation settlement factor quantifying the ground bearing capacity are decoupled and obtained. Based on these factors, the target parameters of the counterweight are determined, and the counterweight telescopic hydraulic cylinder and the luffing winch are jointly driven to adjust the counterweight position. This invention distinguishes between structural deformation and foundation settlement risks through dual-parameter decoupling, achieving dynamic and precise adjustment of the counterweight's center of gravity in two-dimensional space, effectively improving the operational safety of cranes under complex working conditions.
