The invention discloses a self-compacting concrete FRP sleeve reinforcing device and a construction method. A formwork is fixedly arranged on a mounting base, a prefabricated sleeve is arranged on the inner side of the formwork, a column body is sleeved with the prefabricated sleeve, and a filling layer is arranged between the prefabricated sleeve and the column body; the prefabricated sleeve is formed by splicing two semicircular connecting parts, and the fastening strip is arranged on the outer side of the prefabricated sleeve and used for fastening the two connecting parts. According to the device, the uneven surface of the damaged column does not need to be repaired and leveled, early-stage preparation work is reduced, the device is simple in structure and convenient to install, and the construction period is greatly shortened.

The invention discloses a 5G optical cable joint port and a connection method thereof, comprising a housing, a frame is sheathed inside the housing, a wiring duct is connected to the top and bottom of the frame, and the outer side of the wiring duct runs through An optical cable and wire body is provided, the front of the optical cable and wire body is pasted with a connection sticker, the front of the connection sticker is pasted with a heat dissipation sticker, the front of the heat dissipation sticker is pasted with a protective sticker, and the inside of the wiring duct is provided with a strip type groove. The present invention enhances the practicability of the G optical cable connector port by achieving the effect of limiting and sorting the lines. The 5G optical cable connector port and its wiring method solve the problem that the existing 5G optical cable connector port does not have the ability to perform internal circuit inspection. The position is limited, and the internal lines are often entangled after plugging in. In the long run, it will be very troublesome to remove the line, and the quality of the line itself will also be affected after the winding time is long.

The invention discloses a floating breakwater and a method capable of giving consideration to an inner oscillation water column wave energy conversion function. In the floating breakwater capable of giving consideration to the inner oscillation water column wave energy conversion function, the exterior of a floating body is anchored into a seabed through an anchor rope connection sinking block; anoverhauling channel is arranged at the upper part of the floating body; and wave energy conversion related configurations are arranged in the floating body, and comprise an air chamber, an air turbine, a turbine bracket, a linkage shaft, a generator, a cushion layer and an air chamber inner water body. A realization method of the floating breakwater capable of giving consideration to the inner oscillation water column wave energy conversion function comprises the steps of a breakwater arrangement process, a process of the floating body eliminating the wave effect, a wave energy conversion output process and an overhauling process. On the basis of maintaining traditional wave retaining and eliminating functions of the floating breakwater, the wave energy conversion function is realized byusing the oscillation design of water in an air chamber, and the power output in the wave energy conversion process is continuous, so that the reliability is good; the stress design of the breakwateris reasonable, and the durability is excellent; and meanwhile, the construction cost is low, and the engineering production advantages are obvious.

The invention discloses an adjustable automatic lifting device capable of rotating in all directions. The adjustable automatic lifting device comprises a base, a device body, a rotating structure, a mounting plate, a gear ring, a mounting block, a connecting column, a buckling ring, a screw rod, a clamping block and a supporting structure. The adjustable automatic lifting device has the beneficialeffects that the mounting plate is rotationally connected with the base at the bottom through the connecting column, it is guaranteed that the device body can still keep good stability in the rotating process, in the rotating process of the mounting plate, when the mounting block is rotated to be perpendicular to the mounting plate, the screw rod on the mounting block is engaged with the gear ring, and thus the position of the mounting plate at the moment can be fixed; meanwhile, a user can fix the position of the mounting block at the moment through clamping between the clamping block on themounting block and the buckling ring arranged on the top side of the mounting plate, and the screw rod can be rotated in the state that the mounting block is kept vertical; and labor-saving fine adjustment can be conducted on the angle of the device body, and the hoisting accuracy of heavy objects is guaranteed.

The invention relates to the technical field of workbenches, and specifically discloses a workbench for research and development of electronic products, which includes a workbench main body, a support rod and a processing and placing plate. There is a card slot at the top and close to the concave groove, the processing and placing plate is located inside the concave groove opened by the main body of the workbench and a connecting piece is integrally formed at the bottom, between the connecting piece and the card slot opened by the main body of the workbench Movable clamping, through the structural design of the placement slot, the first convex plate, the first telescopic cylinder, the slot and the second return spring, the circuit board can be clamped and fixed effectively, and through the opening, the fixed cylinder, the first The structural design of the return spring, the first connecting rod, the pressing plate and the second limiting plate can effectively limit the processing and placing plate, and avoid the always being in a loose state between the processing and placing plate and the main body of the workbench.
