Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machinery, and in particular relates to a connecting device. Background Art
[0002] The acoustic wave transmission method detection uses the pre-buried acoustic detection tube as the channel of the transducer, and transmits and receives ultrasonic signals through water coupling, so as to judge the quality of the pile body according to the change of the signal. Therefore, the acoustic detection tube should be pre-buried during the construction of the pile body. In recent years, with the popularization of super high-rise buildings and super-large and super-deep underground structures, large-diameter and super-large-diameter bored piles have emerged. The number of pre-buried acoustic detection tubes for the acoustic wave transmission method detection of bored piles is often more than 4, or even more than 5, for a single pile. The connection between the host and the radial transducer in the prior art of the acoustic wave transmission method detection is generally connected by a physical cable.
[0003] The above-mentioned prior art solutions have the following defects: the length of the physical cable limits the distance that the devices can be separated, the physical cable connection increases the difficulty of moving the device or resetting the device position, and there must be male and female plugs at the location where the physical cable is connected to the host. In muddy or water-logged conditions, it is easy for water to enter the joints and damage the expensive ultrasonic transmission detection host. Utility Model Content

[0006] An acoustic detection tube, wherein the acoustic detection tube is arranged on the inner wall of the bored pile;
[0007] A host, wherein the host and the acoustic detection tube are not in contact with each other;
[0008] A radial transducer group, the radial transducer group comprising a first radial transducer and a second radial transducer, the first radial transducer being placed on the inner wall of the acoustic detection tube, the first radial transducer being connected to a first cable, the second radial transducer being connected to a second cable, the first cable and the second cable being connected;
[0009] a signal transmitter, the signal transmitter being detachably disposed on the outer wall of the second radial transducer;
[0010] A signal amplifier, wherein the signal amplifier is arranged on the outer wall of the second radial transducer;
[0011] A signal receiver is detachably mounted on the host.
[0012] Furthermore, it also includes a winding member, which is in a columnar shape, and the first cable is wound around the outer wall of the winding member, and the winding member is fixedly connected to the second radial transducer.
[0013] Furthermore, two axial ends of the winding member extend outward to form limiting portions.
[0014] Furthermore, the bored pile is columnar, and the axis of the sonic detection tube is parallel to the axis of the bored pile.
[0015] Furthermore, the second radial transducer is columnar, the second cable is parallel to the axial direction of the second radial transducer, and the second cable is fixedly connected to the outer wall of the second radial transducer.
[0016] Furthermore, the signal transmitter and the signal receiver are hung on the outer wall of the second radial transducer and the host, respectively.
[0017] The beneficial effects of the utility model are:
[0018] 1. The signal transmitter and the signal receiver are both hung on the outer wall of the second radial transducer and the host. The original interfaces of the signal transmitter and the signal receiver can be modified to adapt to radial transducers produced by different manufacturers. At the same time, the Bluetooth device is economical, easy to repair and replace, and a single Bluetooth device is extremely cheap and cost-effective, which greatly reduces the cost.
[0019] 2. Wireless connection replaces physical wired connection, avoiding connection loss or data transmission interruption caused by physical damage to the physical cable.
[0020] 3. Use wireless connection instead of physical wired connection to ensure the separability between devices, making the transition detection between piles more convenient.
[0021] 4. By using wireless connection instead of physical wired connection, the possibility of water entering the physical cable connector during plugging and unplugging is completely avoided, avoiding the risk of damaging the host of the ultrasonic transmission method detection.
