Abstract
The utility model discloses a detachable circuit seal structure, which comprises a movable seal which can be installed on a drill collar base in a plugging manner. The movable seal further includes a seal base and a seal top cover, wherein the seal base is provided with a containing cavity on the seal base for containing a circuit board, the seal top cover covers the seal base, a seal groove is arranged on a face of the seal base opposite to the seal top cover, a seal ring is installed inside the seal groove, a plug matched with the internal structure of the drill collar base is further arranged on the seal top cover, and the plug is electrically connected with the circuit board through a lead. The detachable circuit seal structure realizes quick plugging, greatly facilitates equipment installation and subsequent maintenance, and further ensures the circuit board to be well sealed without being damaged by fluid passing through a drill collar.
Description
Technical field
The utility model relates to a kind of removable circuit sealing structure that is used on the logging instrument matrix.
Background technology
Usually need that on drill collar some circuit boards are installed and finish relevant test job.As shown in Figure 4, be on drill collar matrix 11, to process rectangular slot in drill collar matrix mounting circuit boards method at present, circuit board 4 is placed wherein, using seal cover 20 flat seals at last.Such sealing structure lid is given a shock and impacts easily and become flexible, and is easy to be subjected to the intrusion of extraneous fluid.
The utility model content
Problem at the prior art existence, the purpose of this utility model is to provide a kind of removable circuit sealing structure, not only can guarantee circuit safety, can realize extracting fast, exchanging, and reliable in HI high impact vibrations seal performance, the convenient installation and follow-up maintenance.
A kind of removable circuit sealing structure of the present utility model comprises: can plug the hydrodynamic reciprocating sealing body that is installed on the drill collar matrix, this hydrodynamic reciprocating sealing body further comprises:
Sealed base offers the container cavity that is used for containment circuit board on the sealing base;
Top pressure closure be located on the described sealed base;
Wherein, on the face relative of described sealed base, offer seal groove, in the sealing groove, sealing ring is installed with described top pressure closure; Also be provided with the plug that matches with drill collar matrix internal construction on described top pressure closure, this plug is electrically connected by lead and described circuit board.
Preferably, on described sealed base, also be coated with the rubber layer that is used for damping.
The utility model seals by circuit board is arranged in the sealed base and by top pressure closure, be electrically connected with the inner socket that is provided with of drill collar by the plug that is arranged on the top pressure closure again, realization links to each other with the devices such as sensor that are installed in drill collar inside, only need be inserted in the corresponding mounting groove that is opened on the drill collar in use and get final product, realized the fast insert-pull connection, reliable in HI high impact vibrations seal performance, be very easy to the installation and the follow-up maintenance of equipment, guaranteed also simultaneously that circuit board is sealed well and can not damaged by fluid by drill collar.

The specific embodiment
The utility model is a kind of removable circuit sealing structure, is installed in the drill collar outside, is easy to safeguard that concrete structure is as follows:
Shown in Fig. 1～3, the utility model mainly comprises can plug the hydrodynamic reciprocating sealing body 1 that is installed on the drill collar matrix 11, this hydrodynamic reciprocating sealing body 1 further comprises: sealed base 2 and top pressure closure 3 offer the container cavity 5 that is used for containment circuit board 4 on sealing base 2; Top pressure closure 3 be located on the sealed base 2, and the top of top pressure closure 3 forms and the suitable arc shaped surface 6 in drill collar matrix 11 surfaces.
On the face relative of sealed base 2, offer seal groove 7, sealing ring 8 is installed in sealing groove 7 with top pressure closure 3.By the sealing structure, just realized the sealing between sealed base 2 and the top pressure closure 3, thereby with circuit board 4 well sealing and fixing in the container cavity 5 of sealed base 2.
On top pressure closure 3, also be provided with the plug 9 that matches with drill collar matrix internal construction, plug 9 is electrically connected by lead 10 and circuit board 4, like this, just can realize circuit board 4 and be installed in the electrical connection that has been connected detecting units such as sensor (not shown go out) in the drill collar matrix 11.Sensors etc. can link to each other with socket in being installed in drill collar matrix 11 by lead, thus being electrically connected at match with socket by plug 9 realization and circuit board 4.
In addition, on sealed base 2, also be coated with the rubber layer 13 that is used for damping, play the effect of damping when being convenient to be fixed to the utility model in the drill collar matrix 11.
When the utility model uses, only need be inserted in the mounting groove of on drill collar 11, offering 14 as shown in Figure 2 and get final product, like this, the fast insert-pull of just having realized board structure of circuit connects, be very easy to the installation and the follow-up maintenance of equipment, guaranteed also simultaneously that circuit board 4 is sealed well and can not damaged by fluid by drill collar.
