AI Technical Summary

Technical Problem

During coalbed methane exploration, sample storage devices are easily damaged in complex terrain and are inconvenient to operate, making it difficult to adapt to the fixation needs of samples of different sizes.

Method used

It adopts a wide elastic rope and ratchet mechanism combined with a buffer spring design. The T-bar drives the wide elastic rope to tighten and fix the sample bottle. The pawl and ratchet form a one-way locking mechanism to prevent loosening. It is equipped with a buffer spring for shock absorption and combined with the seat groove to provide precise positioning.

Benefits of technology

It effectively protects samples in the event of accidental drops or impacts, simplifies the sample fixing and removal process, improves the stability and portability of the device, and ensures sample safety.

Abstract

The invention discloses a sample storage device for coal bed gas exploration, which comprises a storage box, a fixed box is fixedly connected in the storage box, a mounting block is fixedly connected in the fixed box, an extrusion spring is fixedly connected to the bottom of the mounting block, the extrusion spring is fixed above a pawl, and an L-shaped fixed block is fixedly connected above the pawl. According to the device, when the device accidentally falls and is impacted, the impact force can be effectively buffered through the tightening state of the wide elastic rope, meanwhile, the impact force is further dispersed through the buffer spring and the soft plate on the side face of the arc-shaped plate, direct collision between a sample bottle and the inner wall of the device is avoided, and the risk that the device is damaged due to collision and a sample is damaged is remarkably reduced; the sample storage safety is guaranteed, the wide elastic rope can be driven to slide and tighten through the ratchet wheel, the bevel gear and the connecting rod only by rotating the T-shaped rod, the sample bottles of different sizes can be rapidly fixed, the situation that multiple sets of direction fixing devices are adjusted like a traditional device is not needed, and a pressing plate is pressed to control a pawl to be unlocked during disassembly.
