The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of LWD logging system electronic circuit protection device, comprise cylindricality protective cradle, T type flap, offer T type groove on the sidewall of described cylindricality protective cradle, described T type flap and described T type groove are adaptive mutually; Be provided with one deck damping glue in the described T type groove; Electronic circuit is arranged in the described T type groove, and described T type flap covers described T type groove, its arranged outside fluid sealant.
The beneficial effects of the utility model are: electronic circuit is installed in the T type groove of the cylindrical stent that the extraordinary aluminium alloys of aviation, titanium alloy material etc. make, T type groove forms the protecting bin of electronic circuit.Have good heat radiation and effect of heat insulation; and be provided with a side damping glue in the groove; have shock resistance and shock resistance; can resist the concussion environment; the stable operation of protection electronic circuit; electronic circuit system has completely cut off wet environment in T type protecting bin, airtight construction has guaranteed anti-pressure ability, and damping glue can guarantee damping capacity.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, also be provided with temperature pick up, humidity sensor and baroceptor in the described T type groove, temperature, humidity and air pressure signal that described temperature pick up, humidity sensor and baroceptor will detect in the T type groove are carried signal processing apparatus, an output port of described signal processing apparatus is connected with display unit, and another output port connects indication LED emergency warning lamp and loudspeaker simultaneously.
The temperature that described signal processing apparatus receives, humidity, air pressure signal surpass default warning value through judging any one parameter, and the bright or loudspeaker of LED emergency warning lamp is raised one's voice; Just often, display unit shows normal data.
Adopt the beneficial effect of above-mentioned further scheme to be: to have at electronic circuit under the prerequisite of good heat radiating antidetonation, because temperature pick up, humidity sensor and baroceptor also are installed in the electronic circuit environment, can understand the electronic circuit working condition constantly as " black box " in the aircraft, guarantee that the working environment of electronic circuit is stable.
Further, described damping glue is ammonia ester (PU) type glass cement.
Adopt the beneficial effect of above-mentioned further scheme to be: the characteristic of the isolated aqueous vapor of polyurethane (PU) type glass cement can increase the resistance to corrosion of circuit, also can prevent the short circuit that aqueous vapor causes; High-quality polyurethane (PU) type glass cement has good viscosity and elasticity, can play cushioning effect preferably.
Further, described fluid sealant is cured silicone refractory seals glue.
Further, described T type groove is three, is evenly distributed on the excircle of described cylindricality protective cradle.
