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

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The overall structure of the battery compartment and the elastic compensation support structure of the present invention are shown in figure 1 , figure 2 .

[0029] The battery assembly 5 is supported at both ends inside the cabin body 4, and two mounting bolts 3 pass through the battery assembly 5 from one end of the battery assembly 5, and are integrally fixed on the front cover 6 of the cabin body to form a fixed support at the front end; the rear of the battery assembly 5 The NBR rubber elastic compensating O-ring 17 with Shore hardness of 70 embedded in the end ring groove is close to the support cone surface 2 on the cabin rear cover 1 to form a rear end support. The angle of the support cone surface on the rear cover 1 of the cabin is selected from 10°-15°, preferably 12°, so as to reduce the axial component of the elastic compensation O-ring contact...

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. 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 cabi...
