3results about How to "Simplify the drilling process" patented technology

This utility model relates to a drilling mechanism for construction pipelines, including a base plate, a connecting plate on top of the base plate, a fixing component on top of the base plate, and a drilling component on top of the connecting plate. The fixing component includes a frame fixedly connected to the top of the base plate, with a fixing clamp fixedly connected to one end of the frame. This drilling mechanism for construction pipelines allows for easy adjustment of the position of the movable clamp by rotating a torsion bar at one end of a threaded rod, firmly clamping the pipeline between the fixed clamp and the movable clamp. V-grooves on opposite sides of the fixed and movable clamps better accommodate pipelines of different diameters, increasing the contact area and improving stability. The anti-slip texture further enhances the friction between the clamp and the pipeline, effectively preventing the pipeline from slipping during drilling. This ensures the entire device is stably fixed to the pipeline for drilling operations, greatly improving drilling accuracy and guaranteeing construction quality.

The present application belongs to coefficient determination method, and particularly relates to a method for determining the iron water absorption coefficient in gamma logging data interpretation. The method for determining the iron water absorption coefficient in gamma logging data interpretation comprises the following steps: step one, collecting information; step two, calculating the equivalent thickness; and step three, calculating the absorption coefficient. The present application has the following remarkable effects: the method of the present application establishes a fitting function by using the limited discrete data provided by the existing logging model experiment, calculates the iron water absorption coefficient corresponding to different measured borehole diameters by using the function, has high fitting accuracy of the absorption coefficient, and has the advantages of convenient calculation, easy programming, simplified drilling process, and saved drilling construction cost.

This utility model relates to the field of cylindrical lithium-ion battery manufacturing technology, and discloses a cylindrical lithium-ion battery airtightness testing device and system. The testing device includes a clamping mechanism covering the outside of the battery cell; a sleeve fitted onto the outside of the clamping mechanism; a fixed base located at the bottom of the sleeve, with an air inlet channel and a perforation channel connected; a fixed cap located at the top of the sleeve and forming a sealed cavity with the sleeve, fixed base, and battery cell, and having a through hole corresponding to the cap area of ​​the battery cell; a two-way valve located at the bottom of the fixed base and connected to the perforation channel; and a piercing mechanism located at the end of the two-way valve away from the fixed base, used to pierce the battery cell by passing through the two-way valve and the perforation channel when the two-way valve is open. This testing device improves the speed of airtightness testing during battery cell production and enhances the accuracy of the test data.
