Background technology
At present, two transmitting transducers are arranged in the acoustic wave apparatus, two transmitting transducers are normally in receiving transducer is fixed on sound wave sonic system shell.Because sound wave sonic system shell not only needs to bear the weight of whole string logger, but also will bear the strength of crooked and torsional deflection, so sound wave sonic system shell generally all there is thicker wall thickness.Will cause the transmitting transducer diameter in the sound wave sonic system shell to reduce like this, thereby reduce the transmitting power of transmitting transducer, influence the investigative range of whole acoustic wave apparatus.
The utility model content
The purpose of this utility model is: a kind of well logging sound wave transmitter is provided, under the condition that the same size logger requires, improve the outside dimension of pinger to a greater extent, thereby improve the transmitting power of transmitting transducer, improved the quality of acoustic wave apparatus log.
The technical solution adopted in the utility model is: the well logging sound wave transmitter, mainly by lower contact, sound transmitting window, transmitting transducer, locking nut, connector, connection shell, top connection with form communicating pipe, it is characterized in that: lower contact and top connection have centre bore, there is screw thread top connection centre bore lower end and by being threaded communicating pipe, communicating pipe the lower end external screw thread is arranged and by the lower contact upper end centre bore that is threaded.
Be fixed with a connector respectively in the lower end of top connection and the upper end of lower contact; Between two connectors, be connected with cylindric connection shell, on the outer wall that connects shell, radial hole arranged.
Two transverse holes are arranged at top connection middle part, two transverse holes intersect vertically and with centre bore UNICOM; Two transverse holes are arranged at lower contact middle part, two transverse holes intersect vertically and with centre bore UNICOM.
Middle part and lower contact middle part in top connection are fixed with a transmitting transducer cylindraceous respectively, two transmitting transducers are relative with two transverse holes of two transverse holes of top connection and lower contact respectively, by the locking nut of top connection and the locking nut of lower contact two transmitting transducers are separately fixed at top connection and lower contact middle part.
Be fixed with columnar sound transmitting window respectively between top connection outer wall and the connector outer wall and between lower contact outer wall and the connector outer wall.
In order to prevent that connecting shell rotates, and radially is fixed with anti-turn screw between connection shell and connector.
In order to protect sound transmitting window, be with the sound transmitting window protective sleeve at the external surface of sound transmitting window.
In order to improve sealing performance, O-ring seals A is being arranged between lower contact and the sound transmitting window and between top connection and the sound transmitting window; O-ring seals B is being arranged between lower contact and the connector and between top connection and the connector; In lower contact and between communicating pipe and top connection and O-ring seals C was arranged between communicating pipe.
The beneficial effects of the utility model: the utility model well logging sound wave transmitter, under the situation that does not increase the instrument external diameter, increase the outside dimension of transmitting transducer effectively, thereby improved the transmitting power of transmitting transducer, and then improved the quality of acoustic wave apparatus log.
