This utility model discloses a joint mechanism for a humanoid robot. The joint mechanism includes: a first driving member for driving the robot to rotate around a first axis; a second driving member for driving the robot to rotate around a second axis; a first housing having at least two wire holes extending in a planar direction; a second housing having an opening for wires to pass through, and at least two vertical cavities extending in a vertical direction, with their tops connected through the openings and their bottoms connected to the wire holes; the second housing and the first housing are rotatably connected, and both have an installation position and an initial position. In the initial position, the vertical cavities and wire holes are misaligned, and the openings, vertical cavities, and wire holes form a first three-dimensional wiring path; in the installation position, the vertical cavities and wire holes are aligned, and the openings, vertical cavities, and wire holes form a second three-dimensional wiring path; the length of the first three-dimensional wiring path is greater than the length of the second three-dimensional wiring path. This utility model increases the wiring space through the cooperation of the vertical cavities and wire holes.

The present application relates to the technical field of biofuel preparation, and discloses a high-calorific-value stable-combustion bio-blended fuel and a preparation method thereof, which comprises polar ester components, straight-chain alkane components, branched-chain alkane components and halogenated alkane components in a proportion by weight. The preparation method adopts a step-by-step temperature control feeding combined with a stage speed regulation shearing process, heats and melts high-carbon straight-chain alkane to form a liquid-phase matrix, adds isomeric alkane at a high temperature and improves the double-layer stirring speed for mechanical shearing and dispersion, slowly drops the halogenated alkane components and mixes the polar ester components after constant temperature and cooling. Through the synergistic cooperation of multiple categories of hydrocarbons and oxygen-containing compounds, the branched-chain structure steric hindrance is used to interfere with the formation of macromolecular wax crystal network, and the halogenated component is dissociated to control the chain reaction rate. The present application takes into account the high-calorific-value output and stable combustion, suppresses the cylinder knock, improves the low-temperature flow performance of the fuel, and generates a homogeneous transparent liquid.

The present application relates to a kind of quick judgment method of car roof refuge space, specifically comprising the following steps: 1) record each size in car;2) establish car space model;3) establish refuge space model;4) establish quick calculation form;5) comparison judgment.The present application is characterized by: it can quickly determine whether there is refuge space;Mark the refuge space on the car roof, guide the maintenance personnel to quickly run into the refuge space in extreme conditions, ensure the safety of maintenance personnel when encountering extreme dangerous conditions during maintenance work;It can also obtain larger car roof space by design modification (such as type five will be slightly inclined to car roof wheel), to maximize the acquisition of refuge space.If there is no refuge space, it requires the first party / client to change the building design (such as changing the shaft size to increase the car size to obtain more free space, or increasing the top height to ensure that there is standing space on the car roof in extreme conditions), to maximize the saving of construction cost.

The invention discloses a device for improving cavity isolation and application, and the device comprises a housing and a cover plate disposed at the top of the housing, the interior of the housing is provided with a separation rib used for isolating a cavity in the housing, the device also comprises an elastic reed which is disposed at the bottom of the cover plate and clamps the separation rib, and the inner side of the housing is provided with a substrate below the separation rib. And the interior of the shell is divided into two independent cavities by the separation rib and the elastic reed. The elastic reed is designed between the separating rib and the cover plate, good contact between the separating rib and the cover plate is guaranteed through elastic deformation of the elastic reed, a large free space is provided for the allowable range of a gap between the separating rib and the cover plate, and the problem that a shielding loop is not closed due to the fact that the gap exists between the separating rib and the cover plate is solved; therefore, the isolation degree between the cavities is effectively improved. The elastic reeds have high diastolic resistance, elastic deformation can be recovered when the elastic reeds are pulled out of the separating ribs, and the problem of repeated plugging and pulling is solved.
