For those skilled in the art, the specific meaning of the above terms in the present utility model can be understood through specific circumstances.
[0025] The following further describes the present utility model in detail with reference to embodiments.
[0026] Specific embodiments of the backpack-type acoustic imager provided by the present utility model:
[0027] Please refer to Figures 1-5 , the backpack-type acoustic imager, including a backpack body 1 and an acoustic imager body 5; there is a space in the backpack body 1 for accommodating the acoustic imager body 5, which is convenient for the storage of the acoustic imager body 5; carrying the backpack body 1 that houses the acoustic imager body 5 on the back realizes hands-free carrying.
[0028] One side of the backpack body 1 is connected with a shoulder strap 2, and there is an opening on the other side; the number of shoulder straps 2 is two; in this embodiment, the opening of the backpack body 1 is rectangular, and among them, the vertical dimension of the opening is greater than the horizontal dimension. Inside the opening of the backpack body 1, there is a lid 3, and the lid 3 is connected to the backpack body 1 through a zipper 4; specifically, the lid 3 is connected to the lower side edge of the opening. The lid 3 is made of a soft material, such as cloth or leather, etc., and the backpack body 1 is made of a hard material, such as ABS plastic. The outer side of the backpack body 1 is coated and bonded with a soft material, such as cloth or leather, etc.; the soft material on the outer side of the backpack body 1 is integrally connected with the lid 3; the lid 3 and the soft material on the outer side of the backpack body 1 are connected through a zipper 4. The lid 3 can be quickly opened and closed through the zipper 4 to take and place the acoustic imager body 5. In this embodiment, the zipper 4 is arranged in an inverted U shape.
[0029] A telescopic rod 6 is connected between the acoustic imager body 5 and the inner side of the backpack body 1. The telescopic rod 6 has telescopic damping. The telescopic rod 6 with damping can support the weight of the acoustic imager body 5 without telescoping, and it does not affect manual force application to achieve the telescoping of the telescopic rod 6.
[0030] Carry the backpack body 1 in front of the chest. By extending the telescopic rod 6, the acoustic imager body 5 can extend out of the backpack body 1 to detect the detection part. When the acoustic imager body 5 does not need to be manually operated, the body can support the acoustic imager body 5 through the backpack body 1, liberating both hands.
[0031] The telescopic rod 6 is connected to both the backpack body 1 and the acoustic imager body 5 through an angle adjustment component 7. The angle adjustment component 7 enables the angles between the telescopic rod 6 and the backpack body 1 and the acoustic imager body 5 to be adjustable, so that the acoustic imager body 5 has a flexible detection angle to meet the requirements of detecting different parts.
[0032] The angle adjustment component 7 includes hinge seats 71, bolts 72 and wing nuts 73. The number of hinge seats 71 is two. Through holes for the bolts 72 to pass through are provided on both of the two hinge seats 71. The inner diameter of the through holes is larger than the outer diameter of the rod part of the bolts 72. The bolts 72 pass through the two hinge seats 71 and the ends are threadedly connected to the wing nuts 73. In this embodiment, the two hinge seats 71 at the upper end of the telescopic rod 6 are respectively connected to the telescopic rod 6 and the acoustic imager body 5; the two hinge seats 71 at the lower end of the telescopic rod 6 are respectively connected to the telescopic rod 6 and the inner side of the backpack body 1. The two hinge seats 71 can rotate by being supported by the bolts 72 to achieve angle adjustment. By rotating the wing nuts 73, the two hinge seats 71 can be pressed tightly to increase the friction coefficient, so as to achieve the stable support of the load, that is, the acoustic imager body 5.
[0033] In this embodiment, both of the two hinge seats 71 are of comb-tooth type structures, and the tooth parts of the two hinge seats 71 are inserted and matched in a staggered manner; in this way, when the wing nuts 73 press the two hinge seats 71 tightly, the contact surfaces of the two hinge seats 71 are greatly increased, and the load capacity is strong, which can stably support the acoustic imager body 5. The hinge seats 71 can be made of a metal material with a certain elasticity or an ABS plastic material; when a metal material is used, the contact surfaces of the two hinge seats 71 are set to be matte surfaces.
[0034] A display 51 is arranged on one side of the acoustic imager body 5 facing the shoulder strap 2, and a microphone array disk 52 is arranged on the side of the acoustic imager body 5 facing away from the shoulder strap 2. A main board and a rechargeable power source are arranged inside the acoustic imager body 5, and the power source supplies power to the acoustic imager body 5. A number of microphone probes are arranged in an array on the microphone array disk 52. The microphone probes collect signals and transmit them to the main board. The main board realizes sound signal waveform editing and output, signal acquisition control, array measurement, etc., and the output results are presented through the display 51.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions recorded in the foregoing embodiments without creative labor, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
