Abstract
The utility model relates to an installation direction instrument battery module's shell structure in pit. The problem that the underground service time of a small-capacity drilling instrument with a built-in battery is short due to the limitation of the outer diameter of a four-wall slotted type framework placed in the conventional battery nipple structure is mainly solved. The method is characterized in that: 3 semicircular grooves are uniformly distributed on the battery nipple body (1), a step surface is milled at each of two ends of each groove, and a wiring hole (7) is formed in one side of the bottom of one end of each groove in the shell; batteries (4) are placed in the grooves, a protective cover (3) is arranged on the upper portion of each battery (4), and a buckling cover body (2) is arranged on the groove of the battery nipple body (1) on the upper portion of each battery (4); the battery short section body (1) and the buckle cover body (2) are fixed through a plurality of fastening bolts (6). The casing structure for installing the battery module of the underground guiding tool increases the battery capacity, is long in underground service time of the while-drilling instrument, and can supply power to the rotary guiding tool.
Description
Technical Field
The utility model relates to an oil drilling tests technical field in the pit, in particular to casing structure of direction instrument battery module in installation in pit.
Background
The battery short section structure outer wall adopted at present is a drill support type, a four-wall slotted skeleton is arranged inside the battery short section structure outer wall, and batteries are arranged on the four walls of the skeleton. Because the two ends of the battery nipple joint need NC50 threaded connection, the maximum outer diameter of the framework is not larger than 117mm, the number and the specification of the batteries are limited, the electric quantity of the battery nipple joint is small, and the requirement for long-time power supply of a drilling instrument is difficult to meet.
Disclosure of Invention
The utility model aims to solve the technical problem that overcome the limited problem that makes built-in battery capacity little along with boring instrument operating time is shorter in the current battery nipple joint structure interior four wall open slot type skeleton external diameter of placing that exists among the background art, and provide an installation casing structure of direction instrument battery module in pit, this installation casing structure of direction instrument battery module in pit, battery capacity has been increased, instrument operating time in pit is longer along with boring, can supply power to rotation direction instrument, thereby the normal construction and the operation of rotation direction instrument have been guaranteed, compare with conventional battery nipple joint, battery capacity increases 30% -50%.
The utility model provides a its problem accessible reach as follows technical scheme: the shell structure for installing the battery module of the underground guiding tool comprises a battery nipple body, wherein 3 semicircular grooves are uniformly distributed on the battery nipple body, two ends of each groove are respectively milled with a step surface, and the bottom of one end of each groove is provided with a wiring hole at one side in the shell; batteries are arranged in the grooves, a protective cover is arranged at the upper part of each battery, and a buckle cover body is arranged on the groove of the battery nipple body at the upper part of each battery; the battery short section body and the buckle cover body are fixed through a plurality of fastening bolts.
Compared with the above background art, the utility model can have following beneficial effect: the shell structure for installing the battery module of the underground guiding tool is convenient to install and disassemble, the shell is reliable in sealing, and the pressure resistance of the shell structure reaches 70 MPa; the installation of a plurality of sets of battery modules is realized in a limited space, and the battery capacity can be increased by 30-50% compared with that of the conventional battery module.
