3results about How to "Cutting safety" patented technology

The invention provides a single-stage efficient emergency cutting tool and an assembling method thereof. The single-stage efficient emergency cutting tool comprises a first part, a starting device, a second part, an emergency cutting device, a third part and a safety device. One end of the starting device is connected with the emergency cutting device and the other end is connected with the hand pump; the starting device is used for compressing a disc spring in the emergency cutting device of the second part, and elastic potential energy is provided for well descending cutting of a cutting tool in the emergency cutting device through the disc spring. The emergency cutting device adopts a disc spring mechanical energy storage and release principle to quickly cut a steel wire or a cable through a cutting tool; the safety device is installed at the front end of the emergency cutting device, plays a role in safety protection in the assembling process and plays a role in misoperation prevention before cutting. According to the invention, steel wires or cables can be safely and efficiently cut in a high-viscosity fluid well and an inclined well, and a solid guarantee is provided for the success rate and reliability of operation.

The invention provides an image-guided double-radio-frequency acousto-optic deflection laser cell cutting system and method, and the system comprises a microscopic imaging module which is used for collecting a cell image; the imaging control module is used for controlling the microscopic imaging module to collect cell images and extracting contours of the collected cell images to obtain cell contour coordinates; the laser cutting module is used for emitting pulse laser, performing X-direction and Y-direction double-radio-frequency acousto-optic deflection on the pulse laser, and cutting the cell contour by using the obtained deflection laser; and the cutting control module is used for acquiring a mapping relation between the coordinate system of the microscopic imaging module and the radio frequency of the double-radio-frequency acousto-optic deflection to obtain a coordinate-frequency mapping model, and controlling the laser cutting module to perform the double-radio-frequency acousto-optic deflection on the pulse laser according to the cell contour coordinates and the coordinate-frequency mapping model. According to the invention, the cutting welting accuracy and repeatability can be improved.
