A new material supersonic transducer

Abstract

The invention discloses a novel material supersonic transducer. The novel material supersonic transducer comprises an outer shell, an arc cover, and a fastening bolt. A fixed disc is pressed downwards, an upper pressing ring is placed above an annular sleeve, the fixed disc is loosened, a spring upwards pushes the fixed disc, a hollow column on the fixed disc rises along a lifting rod, an arc concave opening on the fixed disc drives a rotating arm to rotate through a pin, the other end of the rotating arm drives a fixed part to rotate through a pin, the fixed part drives a connecting foot to rotate through a connecting part, a first pin hole in the connecting foot and a rotating base on the upper pressing ring rotate through the pin, the connecting foot drives a fixed jaw to rotate, an arcgroove in the fixed jaw clamps the annular sleeve on the outer periphery of the outer shell, and the outer shell is fixed. The technical problems that in the prior art, an ultrasonic transducer shellneeds to be fixed through spiral twisting of a bolt by an operator, and mounting, fixing and dismounting of the transducer are not convenient are solved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic applications, in particular to a supersonic transducer made of a novel material. Background technique [0002] The function of the ultrasonic transducer is to convert the input electrical power into mechanical power (that is, ultrasonic waves) and then transmit it out, while consuming a small part of the power itself. The supersonic transducer is a transducer with higher conversion efficiency. Piezoelectric ceramic sheets are very important materials for supersonic transducers. At present, more and more new ceramic materials have better electrical conversion efficiency and are applied to supersonic transducers. Lead niobate lutetate-zirconate titanate Lead piezoelectric ceramic sheet is one of them. [0003] The patent document (CN201410041437.X) discloses an ultrasonic transducer that can be fixed to the transducer bracket by means of a housing flange, and for this purpose the housing flange...

Problems solved by technology

[0004] The purpose of the present invention is to provide a supersonic transducer made of a new type of material to solve the following technical problems: (1) by pressing down on the fixed plate, the upper pressure ring is placed above the ring sleeve, the fixed plate is released, and the spring pushes up to fix it plate, the hollow column on the fixed plate rises along the lifting rod, the arc-shaped notch on the fixed plate drives the rotating arm to rotate through the pin, the other end of the rotating arm drives the fixed part to rotate through the pin, and the fixed part drives the connecting foot to rotate through the connecting part. The first pin hole on the foot rotates with the rotating seat on the upper pressure ring through the pin, and then the connecting foot drives the fixed claw to rotate, and the arc-shaped groove on the fixed claw engages the annular sleeve on the outer peripheral surface of the housing, thereby completing The fixation of the outer shell solves the technical problem that the ultrasonic transducer shell in the prior art needs to be fixed by the operator screwing the bolt, which makes the installation, fixation and disassembly of the transducer inconvenient; (2) through the outer shell The spiral tube and the water-absorbing material are set on the inner wall of the spiral tube to effectively absorb the moisture near the outer casing and effectively reduce the temperature of the entire transducer. Through the design of the vent hole on the spiral tube, the water vapor in the spiral tube can be exhausted The air hole is discharged by installing a water collection pipe at the end of the spiral pipe away from the exhaust hole, and a floating ball is installed in the inner cavity on the side close to the water collection pipe. The design of the drainage pipe and the water collection pipe can discharge the unevaporated water in the spiral pipe. At the same time, the guide post and the counterweight ball can prevent the connection between the water collection pipe and the drain pipe from being blocked by dust, so as to ensure the use of the spiral pipe and reduce the supersonic energy conversion. Effectively temperature control the moisture around the transducer, effectively increase the service life of the transducer, and solve the problem that the surrounding moisture may penetrate into the shell during the use of the supersonic transducer in the prior art, making the transducer damp, At the same time, when the supersonic transducer is used, because of its ultra-high frequency, it is easy to cause heat accumulation, which will affect the technical problem of the service life of the transducer; (3) through the design of the weight-reducing hole on the fixed claw, the fixed claw can be effectively reduced. The overall weight of the transducer can effectively reduce the overall installation weight of the transducer without affecting the structural strength, which is convenient for the operator to install. By setting the first sealing ring between the first pressing block and the inner wall of the housing, the A second sealing ring is provided between the third pressing block and the inner wall of the housing, and a third sealing ring is provided between the load-bearing block and the inner wall of the housing, which effectively increases the overall airtightness of the housing. The fiberglass cloth can effectively prevent the use of the piezoelectric ceramic sheet and the conductive electrode sheet from being affected by moisture, and solve the problem of poor airtightness of the inner wall of the supersonic transducer in the prior art, while the piezoelectric ceramic sheet and the conductive electrode sheet are easy to be damp. question
