Document Type and Number:
WIPO Patent Application WO/2020/258391
Kind Code:
A1
Abstract:
Disclosed is a dynamic penetration device for underground pipeline detection, relating to the technical field of dynamic penetration devices. The invention solves the following problems: existing dynamic penetration devices require manual labor to record of the number of hammer falls, and when the number is greater than 100, a recording error is prone to occur; during hammering, multiple operators need to support the device by hand so as to ensure that a probe penetrates the soil vertically. A hammer rod is mounted below a handle lock. A hammer is mounted on an outer wall of the hammer rod. Handles are mounted on both sides of the hammer. An anti-slip sleeve is provided on an outer wall of the handle. A hammer fall lock is mounted on one end of the hammer rod. A probe rod is mounted below the hammer dropping lock. A scale line is provided on the probe rod. A probe is mounted on one end of the probe rod. A support frame base is mounted on an outer wall of the probe rod. Extendable support frames are mounted on an outer wall of the support frame base. Three extendable support frames are provided. The extendable support frames are rotatably connected to the support frame base by means of a rotating shaft.
