Offshore wind power installation operation platform
PendingCN121947703ARealize automatic collaborative adjustmentself-lockingVessel safetyWind energy generationMarine engineeringGravity center
The invention relates to the technical field of offshore installation platforms, and particularly discloses an offshore wind power installation operation platform which comprises a floating structure, a leveling device and a gravity center balancing device, and the floating structure can float on the sea; the two leveling devices are symmetrically arranged at the two ends of the top face of the floating structure correspondingly. The gravity center balancing device is arranged at the top output ends of the two leveling devices, the gravity center balancing device can be matched with the two leveling devices, the top face of the gravity center balancing device can be kept horizontal with the sea level, and meanwhile the overall gravity center distribution can be even and stable. Through multi-device cooperative regulation and control and a self-locking limiting structure, self-adaptive stability of the posture and the gravity center of the offshore platform is achieved, and a high-precision operation reference is provided for installation of heavy equipment.

A micro bistable actuator based on shape memory alloy wire driving assembly
PendingCN122504601ASolve the problem of high standby power consumptionself-locking
The application provides a micro bistable actuator based on a shape memory alloy wire driving assembly, relates to the technical field of tactile display and micro actuator, and comprises a mounting frame, a rotating part and a contact element, and the core is that two shape memory alloy wires arranged in an antagonistic mode drive the rotation of an eccentric cam body. In a power-off state, the cam body is kept in a first stable state or a second stable state by using the mass distribution and friction of the cam body, and no continuous power consumption or additional locking structure is needed. The shape memory alloy wire is firmly connected with the cam body through spiral winding and laser welding, zero-power-consumption bistable state keeping is realized, and the problems of large power consumption, large size or low assembly yield of traditional micro actuators are solved. The application has the characteristics of small size, fast response, low power consumption and high production yield, and is suitable for Braille display, micro valve and portable tactile feedback equipment.

Walking type forage grass baling density adjusting device
ActiveCN224192524UResolve inaccuracy and instabilitySelf-lockingBalingAgricultural engineeringStructural engineering
The utility model relates to the technical field of adjusting devices, and discloses a walking type forage grass baling density adjusting device which comprises a square baling bin body, a feeding port is formed in the center of the rear side of the square baling bin body, and a discharging port is formed in the center of the front face of the square baling bin body. Fixing rods are fixedly connected to the positions, close to the top and the bottom of the discharging port, between the inner surface walls of the two sides of the square bundling bin body, pressing plates are rotationally arranged on the outer surfaces of the two fixing rods in a sleeving mode, and first sliding grooves are formed in the positions, close to the two sides, of the outer surfaces of the opposite sides of the two pressing plates; the density adjusting device solves the problems that according to a density adjusting device of a traditional square bundling bin, crank handles on the two sides are generally used for controlling a pressing plate to conduct angle adjustment to control the density of straw bales, adjustment on the two sides is not uniform when workers conduct adjustment, the pressing plate deviates, and the bundled straw bales deform or scatter; and the practicability and the working efficiency of the equipment are reduced.

An aluminum alloy bending machine
This utility model relates to the technical field of aluminum alloy bending machines, and discloses an aluminum alloy bending machine, including a base. A translation mechanism is arranged inside the base, and two right-angle molds are slidably connected to the base via a transmission connection on the outer side of the translation mechanism. An arc-shaped groove is formed on the top of the base, and a bending head is also arranged above the base. Each right-angle mold includes modules, with two modules symmetrically distributed left and right. The opposite sides of the two modules are inclined, and the inclined surfaces of the two modules form a 90-degree angle. A slide rail is fixedly connected to the bottom of each module. This aluminum alloy bending machine has advantages such as ease of use, solving the problem that existing aluminum alloy bending machines can mostly only perform single-shape bending operations, and that adjusting the bending angle often requires changing different bending blocks for extrusion bending, which is very inconvenient.
