Technical Field

[0001] This application relates to the technical field of sonic transmission method detection, and in particular to a zero travel time measurement device for a sonic transmission method detection system. Background Art

[0002] A complete sonic transmission method detection system includes a non-metallic sonic transmission instrument, a transmitting transducer (converting an electrical signal into a sound signal), and a receiving transducer (converting a sound signal into an electrical signal). The non-metallic sonic transmission instrument emits a sound pulse to an object to be measured (concrete), causes it to pass through the object to be measured (concrete), then receives the pulse signal, and determines the integrity of the object to be measured (concrete) based on signals such as the time required for the sound pulse to pass through the object to be measured (concrete), the waveform and amplitude of the received signal, etc. displayed and recorded on the instrument. The time recorded by the non-metallic sonic transmission instrument includes the travel time of the electrical signal generated by the instrument through the acoustic cable to the transmitting transducer, the travel time of the transmitting transducer converting the electrical signal into a sound signal, the travel time of the sound signal through the object to be measured (concrete), the travel time of the sound signal through the housings of the two transducers, the travel time of the receiving transducer converting the sound signal into an electrical signal, and the travel time of the electrical signal through the acoustic cable to be displayed on the instrument.

[0003] To ensure the accuracy of the detection data, the zero travel time of the detection system should be measured before detection to eliminate the influence of electrical delay time, electro-acoustic conversion time, and acoustic delay time on the detection accuracy.

[0004] The existing zero travel time measurement device includes a water tank and a carrier installed in the water tank. A plurality of placement holes are arranged at intervals along the axial direction on both sides of the carrier, and the transmitting transducer and the receiving transducer are respectively placed in the placement holes on both sides of the carrier for data measurement.

[0005] In the above solution, the transmitting transducer and the receiving transducer are placed in the placement holes at different positions on both sides of the carrier, so that different measurement distances are formed between the transmitting transducer and the receiving transducer, thereby obtaining multiple groups of measurement data, and the calculated travel time is more accurate, so as to eliminate the error in travel time calculation. However, the data of the measurement distance between the transmitting transducer and the receiving transducer obtained by the above method is limited, so it needs to be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following is a further detailed description of the present application in conjunction with the attached Figure 1-2 drawings.

[0029] The embodiment of the present application discloses a zero acoustic time measuring device for an acoustic wave transmission method detection system. Refer to Figure 1 and Figure 2The zero-sound time measuring device includes a water tank 1, a supporting plate 2, and two placement blocks 3. The water tank 1 is a rectangular box with an upper opening. The supporting plate 2 is horizontally installed in the water tank 1. The two placement blocks 3 are slidably connected to the upper surface of the supporting plate 2 along the axial direction of the supporting plate 2. The two placement blocks 3 are located at both ends of the length direction of the supporting plate 2. The two placement blocks 3 are provided with placement holes 31 in the vertical direction. The two placement holes 31 are respectively used to place the transmitting transducer 4 and the receiving transducer 5. The receiving transducer 5 is used to receive the ultrasonic signal emitted by the transmitting transducer 4. The water tank 1 is filled with water, and the transmitting end and the receiving end of the transmitting transducer 4 and the receiving transducer 5 are both located below the water surface.

[0030] The specific method of slidingly connecting the placement block 3 to the support plate 2 of the present application is that a slide groove 21 is provided in the middle position of the upper surface of the support plate 2 along the axial direction, and a slider 32 is provided on the bottom of the placement block 3, and the slider 32 is slidably connected to the slide groove 21. The placement block 3 is slidably connected to the slide groove 21 provided on the support plate 2 through the slider 32, so as to facilitate the placement block 3 to move along the axial direction of the support plate 2, thereby improving the accuracy of the movement of the placement block 3. A through hole 22 is provided downwardly along the axial direction along the middle position of the slide groove 21, for the transmitter transducer 4 and the receiver transducer 5 to be placed and extend to the bottom of the support plate 2.

[0031] In order to improve the stability of the placement block 3 slidingly connected to the support plate 2, the slider 32 in the embodiment of the present application is a wedge block, and the slide groove 21 is a wedge groove. In other embodiments, the slider 32 can also be a T-block, and the slide groove 21 is a T-slot.

[0032] In order to improve the working stability of the transmitting transducer 4 and the receiving transducer 5 on the placement block 3, a resisting member 6 is threadedly connected to the placement block 3 and resists the upper surface of the support plate 2. The resisting member 6 in the present application is specifically a butterfly screw made of non-metallic material. After the placement block 3 slides to the corresponding position through the slider 32, the resisting member 6 is rotated to resist the support plate 2, thereby improving the stability of the placement block 3 and further improving the accuracy of data measurement.

[0033] The upper surface of the support plate 2 is provided with a scale 7 along the axial direction, and the scale 7 is extended from the middle position to both sides. The two placement blocks 3 move equidistantly to both sides along the middle zero scale 7, and can accurately and quickly obtain the actual net distance between the transmitting transducer 4 and the receiving transducer 5, and the measurement is simple and efficient, thereby improving the detection efficiency and accuracy when zero sound is detected.

[0034] Mounting plates 8 are fixedly arranged on two opposite inner walls of the water tank 1. The mounting plates 8 are L-shaped, one side of which is fixedly mounted on the inner wall of the water tank 1, and the other side is used to receive and place both ends of the supporting plate 2. The supporting plate 2 is fixedly arranged on the mounting plates 8 by bolts, so that the supporting plate 2 is fixedly arranged between the two mounting plates 8. Both ends of the supporting plate 2 can be more stably fixed on the water tank 1 through the mounting plates 8.

[0035] In order to reduce the influence of the propagation of ultrasonic waves emitted by the transmitting transducer 4 during the measurement of data, the structures of the measuring devices in this application are all made of non-metallic materials. Specifically, the structures of the measuring devices in this application are made of rigid plastic materials.

[0036] The implementation principle of the zero-time measurement device of an acoustic wave transmission method detection system according to an embodiment of this application is as follows: The transmitting transducer 4 and the receiving transducer 5 are respectively placed on the placing blocks 3 on both sides of the supporting plate 2 through the placing holes 31. Since the placing blocks 3 are slidably connected to the supporting plate 2, they can slide freely, so as to control different measurement distances between the transmitting transducer 4 and the receiving transducer 5, measure a large number of data with different distances, make the calculated acoustic time more accurate, and then eliminate the error in the calculation of the acoustic time, and improve the detection accuracy of the final zero-time.
