The invention provides a device and method for quickly coupling a large divergence angle laser to a single-mode optical fiber with a simple structure, small volume, and suitable for coupling a large divergence angle laser. The invention comprises a laser chip, a collimating mirror, a beam splitter, a corner cube, an industrial camera, a coupling objective lens and a fiber optic circulator; the method for optical fiber coupling is as follows: light the laser chip, pass through the beam splitter and the corner cube, and place it in the industrial camera A reference spot is formed on the upper surface of the fiber laser, and the fiber laser is turned on. The laser beam emitted by the fiber laser is incident from port 1 of the fiber circulator, and then exits from port 2 of the fiber circulator. Imaging in the industrial camera to form a coupling spot; finally, the reference spot and the coupling spot in the industrial camera image coincide, indicating that the laser chip (1) is in the same alignment as the coupling end face of the single-mode fiber to be coupled, and the coupling is completed. The invention can be applied to the field of optical fibers.

This invention with uses in in the duplicate building or the villa staircase related, for new assembly type structure lignin staircase. Its Liang Ban with treads boardwalk and in the vertical bar contact face supposes several screw aperture, depth of hole is smaller than the screw total length; Treads boardwalk in the bottom surface and the vertical bar internal surface supposes several cross sections to become the step-shaped scoop channel, in the scoop channel riser the heterogeneous type passes the trough the fitting, passes the trough the geometry size with to install screw head and the endless screw diameter matches on the Liang board, the scoop channel shape and the size and the connection the fitting external dimensions match with this scoop channel in, the scoop channel depth and the Liang board screw aperture sum of the depth is bigger than is equal to the screw total length. This invention originally the structure which will contact for the lignin material and the metal screw transforms into by material and the metal screw contact structures and so on metal, has avoided the staircase pan damage; Simultaneously middle the fitting may circle its periphery wilfully to revolve, when assembly building footboard its angle may wilfully adjust, assembly nimble, the work efficiency is high. Staircase whole artistic natural, varnishes the effect to be specially good.

The invention provides an automatic bridging system. The automatic bridging system uses a single bridging unit as a main body, wherein each bridging unit comprises a moving platform, a support module, a regulating platform and an intelligent operating platform. A using method of the automatic bridging system comprises the following steps: firstly, the bridging system supports a prefabricated component on one vertical-crossing sides of piers, and then the regulating platforms rotate by a certain angle, so that the prefabricated component rotates together; support columns of the regulating platforms support the prefabricated component, and after the height of the prefabricated component exceeds supporting structures at the upper parts of the piers, the regulating platforms rotate; when the prefabricated component and the vertical crossed diameter of the piers are parallel and arranged on a plane which is perpendicular to a level surface, the support columns fall until the prefabricated component is close to the pier supporting structures. The automatic bridging system disclosed by the invention has the characteristics of high intelligence, high automation, high precision and the like. The automatic bridging system disclosed by the invention is not limited by bridges, and the clearance height above overheads.

The invention discloses a coil conveying device of a heat shrinkage film wrapping machine. The coil conveying device comprises a clamping claw mechanism used for clamping the inner circle of a coil, and a film clamping mechanism used for clamping the outer circle of the coil. The clamping claw mechanism comprises a plurality of clamping claws annularly distributed, a push rod driving the clamping claws to be opened and closed in the radial direction at the same time, and a first driving element driving the push rod to move up and down. The film clamping mechanism comprises a plurality of clamping rods annularly distributed on the outer sides of the clamping claws, and second driving elements driving the clamping rods to be overturned, opened and closed. During work, the first driving element drives the push rod to move downwards, the push rod drives the clamping claws to be opened outwards in the radial direction to be clamped on the inner circle of the coil, and the second driving elements drive the clamping rods to be overturned downwards to be clamped to the outer circle of the coil. According to the coil conveying device, the clamping rods are arranged on the outer sides of the clamping claws, a packaging film wrapping the coil is clamped and positioned through the clamping rods, the situation of dislocation in the moving process cannot happen, the packaging film is constantly kept to wrap the coil intactly, and therefore the attractiveness of a finished coil packaging product is improved.

The invention discloses a method for removing fluorescent liquid in an aero-engine compressor casing. The method is used for carrying out fluorescent flaw detection on blades of the 3-7-stage compressor casing and cleaning away penetrating liquid. Cold air and a water vapor spraying gun are adopted for purging a blade installation groove in the upper end face of the 4-7-stage part of the compressor casing and a stopping block installation site in the 3-stage part of the compressor casing so that the penetrating liquid can flow out from a casing gap or the other stopping block installation site; hot water is adopted for cleaning in winter, redundant penetrating liquid on the surface is cleaned away, and to prevent excessive cleaning, only the water vapor spraying gun and hot water can be adopted for cleaning rather than cold air is directly adopted for purging; the casing is placed in a developing tank for development after being dried. Post-cleaning is carried out on the casing after a flaw detection result shows that the casing is up to standard, and because a small amount of penetrating liquid which does not influence flaw detection quality remains in the gap, cleaning after flaw detection is necessary. The casing is placed in the hot water to be soaked, compressed air and the water vapor spraying gun are adopted for purging the blade installation groove in the upper end face of the 4-7-stage part of the compressor casing and the stopping block installation site in the 3-stage part of the compressor casing till no penetrating liquid flows out of the gap, and the casing is dried through a fan or an oven. By means of the method, the cost is lowered, the production cycle is shortened, and the production quality is improved.

The invention discloses a water source heat pump central air-conditioning water source well internally and externally welded in the same well recharge device, comprising a water source well and a well cover, an inner well pipe and an outer well pipe, a water outlet pipe, a return pipe and a water pump, the inner well pipe The outer well pipe is composed of multi-section unit bodies, which are respectively: well pipe section unit body, isolation section unit body, wellhead unit body and well bottom unit body. The invention can be manufactured and processed industrially, unifies and standardizes product specifications, avoids the problem of axial misalignment of inner and outer wells, ensures operability of sealed connection, and improves the quality of sealed butt joint. It is conducive to rapid and accurate positioning and construction on site. It avoids the trouble of proofreading after installation and the problem of poor butt seal after installation. The speed of pipe installation is at least doubled, and the time for later maintenance and replacement of submersible pumps is shortened from 3 to 4 days to 7 to 8 hours. .
