[0002] In recent years, the demand and application of internal inspection equipment for oil and natural gas transmission pipelines have become more and more extensive. The sealed compartments of high-power transmitters that are suitable for high-temperature, high-temperature and high-pressure environments in oil and natural gas pipelines are currently made of carbon steel, which has poor corrosion resistance. , heavy, and does not meet the requirements of good electromagnetic wave signal transmission antennas; the battery compartment and the antenna compartment are generally designed as two independent airtight compartments, which occupy a large space, and the system design and connection are complicated; the antenna compartment generally adopts a ring Oxygen glue is used for potting. Although the reliability is high, it is not maintainable. Once the core coil or circuit board fails, the entire antenna compartment can only be scrapped, and the cost is high; the cover screw generally acts directly on the contact with the end cover. The surface of the shell, disassembled many times, resulting in the sealing of the transmitter can not meet the use requirements

Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, a sealed cabin suitable for multi-media, high-low temperature, high-pressure and high-power transmitters includes a battery compartment end cover 1, a battery compartment shell 2, an adapter plate 3, a flower plate 4, an antenna compartment shell 5, and an antenna compartment end Cover 6, switch cover 10. The battery compartment end cover 1 is fixed on one end of the battery compartment shell 2 by bolts 7 and nuts 8, the adapter plate 3 is fixed on the other end of the battery compartment shell 2 by bolts 9, and the faceplate 4 is also fixed on the battery compartment shell by bolts 11. On the other end of the cabin shell 2, the adapter plate 3 and the faceplate 4 are nested in a spline-like form, one end of the antenna cabin shell 5 is fixed on the faceplate 4 by bolts 12, and the antenna cabin end cover 6 is connected by bolts 12 ...
