This utility model discloses a Z-shaped friction damping column structure with enhanced seismic performance, comprising a Z-shaped friction damping column body, which includes columns on both sides and Z-shaped crossbars between the columns. The top and bottom of the Z-shaped crossbars between the columns are respectively provided with top friction damping diagonal braces and bottom friction damping crossbars. When an earthquake generates a load on the rack in the direction perpendicular to the aisle, and the axial force caused on the base and the bottom and top diagonal braces exceeds the preset friction force, the damper will begin to slide, absorbing or dissipating some of the seismic energy in the form of friction damping. This reduces the probability of damage to rack structural components and goods slippage under seismic conditions, thereby enhancing the overall seismic performance of the industrial rack.

This utility model relates to a camera device for a mud discharge valve, which includes an adjustment component for driving a camera to move above a plurality of mud discharge valves. The adjustment component includes a transverse slide rail laid along a first direction X defined by the line connecting the plurality of mud discharge valves. A base is slidably connected to the transverse slide rail. A vertical slide rail is connected to the upper surface of the base along a second direction Y orthogonal to the transverse slide rail. A slider is slidably connected to the vertical slide rail. A support arm is detachably connected to the surface of the slider along a third direction Z orthogonal to both the transverse and vertical slide rails. A steering plate and a protective cover partially covering the steering plate are disposed at the end of the support arm away from the slider. The steering plate, which can rotate in parallel with the plane defined by the transverse and vertical slide rails, is connected to the camera so that the rotation of the steering plate can drive the camera to enter and exit the protection range of the protective cover.

This invention relates to the field of skiing training assistance equipment, and discloses a tracked powered skiing assistance system, including a mobile power platform, a traction connection mechanism, a sensing unit, and a control system. The traction connection mechanism includes a traction arm body, a telescopic buffer unit, and a damping adjustment unit, providing telescopic buffering capability in the axial direction and restricted swaying capability in the lateral direction. The sensing unit acquires traction load information and user posture information. The control system constructs a coupled control model based on the traction load and user posture, adjusts the traction output and motion trajectory of the mobile power platform, and adjusts the damping according to the rate of change of the traction load to suppress swaying and reduce impact. Simultaneously, the system also features closed-loop traction control, safety control, and virtual slope simulation functions. This invention can achieve responsive control of the user's skiing intentions, improve skiing stability and safety, and is suitable for both snow and non-snow skiing training scenarios.
