Double-path multi-section battery compartment resistant to vibration and easy to maintain

Abstract

The invention provides a double-path multi-section battery compartment resistant to vibration and easy to maintain. The double-path multi-section battery compartment includes a compartment body rear cover, a support conical surface, battery pack mounting bolts, a compartment body, a battery pack, and a compartment body front cover, and is characterized in that the compartment body rear cover is fixedly mounted on a flange at the rear end of the compartment body, the compartment body front cover is fixed on a flange at the front end of the compartment body, the battery pack is arranged in the compartment body, the mounting bolts pass through the battery pack overall from the rear end of the battery pack to be fixed on the compartment body front cover, an elastic compensation support is arranged at the rear end of the battery pack, an annular groove used for mounting a rubber elastic compensation O-shaped ring is formed on the peripheral wall at an end part of the elastic compensation support, an annular boss is arranged inside the compartment body rear cover, the inner wall of the annular boss is a conical surface with the cross section gradually enlarged outward in the axial direction, and the elastic compensation support is supported on the conical inner wall of the annular boss through the rubber elastic compensation O-shaped ring.

Description

technical field [0001] The invention relates to a battery compartment, in particular to a vibration-resistant and easy-to-maintain dual-circuit multi-cell battery compartment. Background technique [0002] In recent years, in the application of the working power supply of the internal detection equipment of oil and natural gas transmission pipelines, due to the high vibration conditions and long working hours during the operation of oil and natural gas pipelines, the requirements for the environmental adaptability and reliability of the equipment are high. The multi-cell battery module power supply usually adopts the combination method of potting and sealing at home and abroad. This method makes the battery preparation complicated, and the battery fixture cannot be reused.

AI Technical Summary

Problems solved by technology

The multi-cell battery module power supply usually adopts the combination method of potting and sealing at home and abroad. This method makes the battery preparation complicated, and the battery fixture cannot be reused.

In order to realize the maintenance operation of convenient installation and removal of battery components in the cabin, a gap is generally left between the battery component and the inner wall of the cabin at home and abroad at present, and the existence of the gap will inevitably cause the vibration response of the battery pack to be amplified, which is not conducive to the long-term reliability of the battery pack use

The existing way to reduce the installation gap is to set positioning pins on the end surface of the equipment. When the equipment is installed in place, the positioning pins are inserted into the pin holes on the end surface of the cabin for positioning, relying on the small gap between the positioning pins and the pin holes to reduce the vibration response of the equipment, and The displacement of the battery assembly relative to the cabin cannot be fully restricted
