Description

Известны ультразвуковые зонды с пьезоэлектрическим преобразователем и волноводом дл  передачи колебани к преобразователю.Ultrasonic probes with a piezoelectric transducer and a waveguide for transmitting vibrations to the transducer are known.

В предлагаемом зонде осуществлена быстра  смена волновода и пьезоэлемента. Это достигаетс  тем, что в нем применена бобышка с прикрепленной гибкой мембраной, зажатой по периметру дл  звукоизо .л ции и герметизации между резиновыми прокладками. К 6o6bTUJKe с одной стороны прикреплен волновод, а с другой - пьезоэлемент.In the proposed probe, the waveguide and the piezo element are quickly changed. This is achieved by using a boss with an attached flexible membrane clamped around the perimeter for sound insulation and sealing between rubber pads. A waveguide is attached to 6o6bTUJKe on the one hand, and a piezoelectric element on the other.

На чертеже показан зонд в продольном разрезе.The drawing shows the probe in longitudinal section.

Пьезоэлемент / располагаетс  в углублении стакана 2 и прижимаетс  к металлической бобышке 3 с помош,ью пружины 4 и винта 5. К бобышке припа на гибка  мембрана 6, котора  зажимаетс  по периметру между двум  резиновыми прокладками 7 и S с помогцью винтов (показаны их оси), прит гиваюш их фланец 9 к венчику стакана 2. Волновод 10 ввинчиваетс  в бобышку. Колебани  из точки, где производ тс  измерени , передаютс  к пьезоэлементу / через открытый конец волновода 10 и бобышку 3. Боковые поверхности волновода изолированы в акустическому; отношенииС помош,ью эластичного чулка //. Электрическими полюсами зонда  вл ютс  винт 5 и мембрана 6, соединенные электрически через пружину 4 и бобышку 3 с обкладками пьезоэлемента. В конструкции зонда предусмотрена возможность размеш ени  усилител  (лампового или полупроводникового) в корпусе (трубке) 12. JKopnyc прит гиваетс  винтами к венчику стакана 2. Резинова  прокладка 13 служит дл  герметизации . Полна  герметичность и возможность акустической изол ции пьезоэлемента позвол ет производить измерени  с предлагаемым зондо.м при полном погружении его в воду.The piezoelectric element / is located in the recess of the glass 2 and is pressed against the metal boss 3 with the help of spring 4 and screw 5. The membrane 6 is flexed to the boss, which is clamped around the perimeter between two rubber gaskets 7 and S with screws (their axes are shown) , draw their flange 9 to the rim of the glass 2. The waveguide 10 is screwed into the boss. The oscillations from the point where the measurements are made are transmitted to the piezoelectric element / through the open end of the waveguide 10 and the boss 3. The side surfaces of the waveguide are insulated in acoustic; relation With help, elastic stocking //. The electrical poles of the probe are a screw 5 and a membrane 6 connected electrically through the spring 4 and the boss 3 with the plates of the piezoelectric element. The probe is designed to allow the amplifier (lamp or semiconductor) to be placed in the housing (tube) 12. JKopnyc is screwed to the rim of the cup 2. The rubber gasket 13 serves for sealing. The complete tightness and the possibility of acoustic isolation of the piezoelectric element makes it possible to measure the proposed probe probe with its full immersion in water.
