TECHNICAL FIELD

[0001] The utility model relates to a new sealing structure of ultrasonic probe, specifically a sealing waterproof structure which is simple in structure, easy to install and good in reliability. BACKGROUND

[0002] With the state's increasing emphasis on water resource conservation and the monitoring, measurement and reconstruction of pipes of various diameters in the water supply industry, the demand for electromagnetic flowmeters in the market is gradually increasing. Under such circumstances, the demand for pipe section type ultrasonic electromagnetic flowmeters combining the two measurement principles of electromagnetism and ultrasonic waves for fluid media with small flow rate is also increasing. Against this background, the sealing structure of the ultrasonic probe is particularly important.

[0003] The conventional ultrasonic probe is usually fixed by simple methods such as screw locking or gasket pressing to achieve the purpose of sealing, but the vibration of the ultrasonic probe when generating sound waves is ignored. That is, the sealing is achieved by simple and rough locking or pressing, which reduces the measurement accuracy of the probe and causes large measurement errors. The new ultrasonic probe sealing structure can effectively avoid the above-mentioned situations of reduced accuracy and large errors. SUMMARY

[0004] The utility model discloses a kind of sealing fixed structures of cylindrical ultrasonic probe of simple structure, easy to install, reliable function, strong economy, it is very suitable for electromagnetic flowmeter, use is more reliable.

[0005] To achieve the above object, the technical scheme of the utility model is as follows:

[0006] The ultrasonic probe sealing structure contains ultrasonic probe horn, ultrasonic probe, silica gel buffer protection sleeve, sealing filling glue, ultrasonic probe mounting chamber, inner hexagonal screw, chamber cover plate, catheter, and is characterized by:

[0007] The ultrasonic probe mounting chamber and the catheter are concentrically welded together;

[0008] The ultrasonic probe horn is connected together with the ultrasonic probe mounting chamber by welding;

[0009] The top of the silica gel buffer protection sleeve is provided with a wire hole, and the lead wire of the ultrasonic probe is inserted from the top hole of the silica gel buffer protection sleeve, and the whole probe is inserted into the protection sleeve;

[0010] The ultrasonic probe horn is provided with a circular groove, the probe wrapped in the silica gel buffer protection sleeve is inserted into the circular groove of the ultrasonic probe horn, and the probe end surface is pressed to fit with the plane in the groove of the horn.

[0011] The sealing filling glue fills the space between the ultrasonic probe installation chamber and the probe;

[0012] The lead of the probe passes through the chamber cover plate;

[0013] The cover plate is locked and fixed with the ultrasonic probe chamber through the hexagonal socket screw and the screw hole.

[0014] The ultrasonic probe sealing structure has the advantages that:

[0015] (1) The ultrasonic probe sealing structure is simple in structure and convenient to operate, and does not have any adverse disadvantages to the measurement of the ultrasonic probe.

[0016] (2) The ultrasonic probe sealing structure is low in cost, and can effectively improve the precision of the ultrasonic probe test and reduce the measurement error. BRIEF DESCRIPTION OF DRAWINGS

[0019] The technical scheme of the present application will be described in detail below in combination with the specific embodiments and the drawings.

[0020] As shown in the drawings: the ultrasonic probe sealing structure comprises an ultrasonic probe horn (1), an ultrasonic probe (2), a silica gel buffer protection sleeve (3), a sealing filling glue (4), an ultrasonic probe installation chamber (5), a hexagonal socket screw (6), a chamber cover plate (7), and a catheter (8). Figure 1 The ultrasonic probe installation chamber and the catheter are concentrically welded together; the ultrasonic probe horn is connected to the ultrasonic probe installation chamber through welding; and the ultrasonic probe installation chamber is made of stainless steel, which can effectively reduce the rusting of the part due to long-term exposure to water or a humid environment.

[0021] The top of the silica gel buffer protection sleeve is provided with a wire hole, the lead of the ultrasonic probe is passed out from the top small hole of the silica gel buffer protection sleeve, and the probe is inserted into the protection sleeve as a whole; since the silica gel buffer protection sleeve is coated, the slight vibration generated during the power-on operation can be effectively absorbed and relieved by the silica gel sleeve, that is, the probe can vibrate within a limited space; therefore, the measurement accuracy of the probe is improved.

[0023] ​​The ultrasonic probe horn mouth is provided with a circular groove, the probe wrapped with a silica gel buffer protection sleeve is inserted into the circular groove of the ultrasonic probe horn mouth, and the probe end surface is tightly attached to the plane in the groove of the horn mouth.

[0024] The sealing filling glue fills the space between the ultrasonic probe installation chamber and the probe; ensures that the sealing filling glue can fully fill the entire space and gap; and the filled filling glue is flush with the outer plane of the chamber, and then is static, waiting for the filling glue to solidify.

[0025] After the filling glue solidifies, the lead wire of the probe is inserted into the cavity cover plate, and then the cover plate is locked and fixed with the screw hole on the ultrasonic probe cavity by using an internal hexagonal screw.
