The utility model relates to the field of textile auxiliary instrument, concretely relates to a cleaning mechanism of double twister, including casing, guide wheel and guide wire bar still include: fixed in the wire guide plate of casing, its opening has wire hole, wire hole, guide wheel and guide wire bar are sequentially arranged along the yarn conveying direction, fixed in the lower cleaning box of wire guide plate, and located between guide wheel and guide wire bar, set up in the upper cleaning box of lower cleaning box top, the utility model discloses through setting up the rotation pipe of single -hand operation and the linkage mechanism of lifting rod linkage, only need to rotate lower locking piece when changing the line can drive the vertical rise of upper cleaning box, make the quick separation of upper and lower cleaning box, do not need to manually wear yarn, greatly simplify the operation process. Especially suitable for multi -spindle position production scene, significantly shorten the line changing time, improve overall production efficiency.

This invention relates to the field of 10kV distribution network live-line working technology, and particularly to a three-phase cooperative adaptive dual-circuit drain wire safety distance control device and method. The device includes a clamp, a rotating shaft, an elastic band, a locking assembly, an insulating rod, and a distance control assembly. The clamp houses the elastic band via the rotating shaft and is secured with a hook. The locking assembly uses a ratchet and pawl mechanism for self-locking. The distance control assembly achieves precise adjustment through an adjusting cylinder and a lead screw. The control method includes four steps: parameter pre-acquisition and calibration, device pre-installation and positioning, three-phase drain wire clamping calibration, and three-phase cooperative adaptive adjustment. This invention solves the problem of insufficient safety distance caused by the natural sag of drain wires during 10kV live-line distribution network bypass uninterrupted operation. It can respond in real time to changes in the environment and operating parameters, achieving three-phase cooperative adaptive adjustment, improving operational safety and stability, meeting the requirements of uninterrupted operation, and has a wide range of applications.

The invention relates to a security device for building construction and a mounting method thereof. The security device comprises an up-down arm, and an up hanging piece and a down hanging piece which are arranged on the up-down arm; the upper arm and the lower arm are rotationally connected to the U-shaped hinge seat, so that the upper arm and the lower arm can be opened and closed relatively; a self-locking mechanism is arranged on the U-shaped hinge seat and is used for carrying out self-locking positioning on the opening and closing angle of the descending arm after the descending arm rotates relative to the ascending arm; the ascending arm and the descending arm are both rectangular pipes, core pipes are fixed in pipe cavities of the ascending arm and the descending arm, the outer wall of each core pipe is sleeved with an auxiliary arm in a sliding mode, an outer adjusting groove is formed in the ascending arm in the length direction, an inner adjusting groove is formed in the core pipe in the length direction, and the inner adjusting groove and the outer adjusting groove are arranged in an inner-outer coincident mode. The descending hanging piece is hinged to the tail end of the other auxiliary arm; the ascending hanging piece comprises a first hanging rod hinged to the tail end of the auxiliary arm and a second hanging rod in sliding fit with the overlapping position of the inner adjusting groove and the outer adjusting groove, and the second hanging rod slides along the inner adjusting groove and the outer adjusting groove so as to adjust the position relative to the first hanging rod.
