[0037] In the following, the embodiments of the present application will be described with reference to the drawings. In the drawings, the same reference signs represent the same or similar parts, or the same or similar steps.

[0038] In order to solve the problem that the small gap inside the hollow pier is not easy to be found in the prior art, and the cost of using the geological radar for detection is high and is not convenient for daily detection, and the problem that the existing hollow pier detection device needs the operator to enter the inside of the hollow pier through the inspection opening, and the detection device needs to be installed or debugged on site before the detection operation can be carried out, which not only has a large workload but also has a certain safety hazard.

[0039] The utility model provides a kind of hollow pier automatic monitoring device, unlike the detection mode that operator enters the inside of hollow pier in prior art, the hollow pier automatic monitoring device of the utility model is set in advance on hollow pier, can realize online monitoring function, according to need daily or every interval a period of time timing detection, or according to weather condition, special event etc.

[0040] On the one hand, the utility model embodiment provides a kind of hollow pier automatic monitoring device, as shown in Figure 1 And Figure 2 As shown, the automatic monitoring device includes a sound wave detection component 11, the sound wave detection component 11 includes at least two sound wave sensors 111, each sound wave sensor 111 includes a sound wave transmitter 111-1 and a sound wave receiver 111-2, and the sound wave transmitted by the sound wave transmitter 111-1 of one sound wave sensor 111 can be received by the sound wave receiver 111-2 of any other sound wave sensor 111, the sound wave sensor 111 transmits a sound wave signal of a specific frequency to the outside when the sound wave transmitter 111-1 is working, and receives a corresponding sound wave signal when the sound wave receiver 111-2 is working;Each of the sound wave sensors 111 is fixedly arranged on the inner wall and / or outer wall of the hollow pier 2 according to a specific arrangement, for detecting defects inside the hollow pier 2;The connecting part of the sound wave sensor 111 and the flat wall and / or curved wall of the hollow pier 2 is provided with a coupling structure 12.

[0041] The coupling structure 12 is used to improve the detection accuracy and stability, which is used to fill the small gap between the acoustic wave sensor 111 and the hollow pier 2, isolate the air, reduce the energy loss of the acoustic wave signal in the transmission process, and enable the acoustic wave to propagate smoothly, thereby improving the accuracy of the acoustic wave sensor 111 when measuring. For example, the coupling structure 12 can be selected from special adhesives, concrete and the like.

[0042] The hollow pier automatic monitoring device in the above embodiment is pre-installed on the hollow pier, and the detection work of the hollow pier can be completed by controlling the automatic monitoring device by the staff at a remote end. The worker does not need to climb into the high hollow pier during detection, which not only avoids the safety hidden trouble in the operation process, but also reduces the workload of the detection operation. The automatic monitoring device can also detect and identify the small defects in the hollow pier that are not easy to find, especially the internal cracks that have a greater impact on the structure of the hollow pier, which can be accurately identified and detected, and is conducive to improving the accuracy of the hollow pier defect detection. The setting position of the acoustic wave sensor 111 can include the following embodiments according to the inside and outside of the hollow pier.

[0043] In the first embodiment, the top acoustic wave sensor 111-A and the bottom acoustic wave sensor 111-C can be arranged on the inside of the hollow pier, and the middle acoustic wave sensor 111-B can be arranged on the outside of the hollow pier. For example, when the hollow pier structure between the top acoustic wave sensor 111-A and the middle acoustic wave sensor 111-B needs to be detected, the acoustic wave transmitter 111-1 of the top acoustic wave sensor 111-A sends an acoustic wave signal to the middle acoustic wave sensor 111-B below it, and the acoustic wave signal is received by the acoustic wave receiver 111-2 of the middle acoustic wave sensor 111-B after propagating through the hollow pier structure, or the acoustic wave transmitter 111-1 of the middle acoustic wave sensor 111-B sends an acoustic wave signal to the top acoustic wave sensor 111-A above it, and the acoustic wave signal is received by the acoustic wave receiver 111-2 of the top acoustic wave sensor 111-A after propagating through the hollow pier. By comparing the transmission and reception time of the acoustic wave signal or analyzing the waveform change of the acoustic wave signal, it can be determined whether there is an internal defect such as a crack, a cavity, water ingress, etc. The principle is that when the acoustic wave signal propagating in the hollow pier passes through a structure defect such as a crack, a cavity or liquid water, the propagation speed and acoustic energy of the acoustic wave signal will change greatly due to the change of the medium type. By comparing the normal acoustic wave propagation data with the detected acoustic wave data, it can be determined whether the hollow pier has a defect, and the type of the defect can be further determined by analyzing the acoustic wave signal.

[0044] In the second embodiment, the top acoustic wave sensor 111-A, the bottom acoustic wave sensor 111-C, and the middle acoustic wave sensor 111-B can all be located inside the hollow pier. For example, when it is necessary to detect the hollow pier structure between the top acoustic wave sensor 111-A and the middle acoustic wave sensor 111-B, the acoustic wave transmitter 111-1 of the top acoustic wave sensor 111-A sends an acoustic wave signal to the hollow pier structure. The acoustic wave signal propagates obliquely downwards, and after reaching the outer wall of the hollow pier, the acoustic wave is reflected and received by the acoustic wave receiver 111-2 of the middle acoustic wave sensor 111-B. By filtering and analyzing the received acoustic wave signal, it can be determined whether there are defects inside the hollow pier structure.

[0045] In the third embodiment, the top acoustic wave sensor 111-A, the bottom acoustic wave sensor 111-C, and the middle acoustic wave sensor 111-B can all be located on the outside of the hollow pier. For example, when it is necessary to detect the hollow pier structure between the bottom acoustic wave sensor 111-C and the middle acoustic wave sensor 111-B, the acoustic wave transmitter 111-1 of the bottom acoustic wave sensor 111-C sends an acoustic wave signal to the hollow pier structure. The acoustic wave signal propagates obliquely upward. After reaching the inner wall of the hollow pier, the acoustic wave is reflected and received by the acoustic wave receiver 111-2 of the middle acoustic wave sensor 111-B. By filtering and analyzing the received acoustic wave signal, it can be determined whether there are defects inside the hollow pier structure.

[0046] In the above embodiments, the advantage of setting acoustic wave sensors 111 on both the inner and outer walls of the hollow pier is that during the detection process, the acoustic wave signal propagates along an inclined straight line, and there is less refraction or reflection along the propagation path. Therefore, the waveform noise of the acoustic wave signal received by the acoustic wave sensor 111 is low, it is not easily interfered with, and the data is easy to analyze and calculate. The advantage of setting the acoustic wave sensors 111 on the inner side of the hollow pier is that it can reduce the influence of the external environment on the acoustic wave sensors 111, which is conducive to extending the service life of the sensors and improving their durability. The advantage of setting the acoustic wave sensors 111 on the outer side of the hollow pier is that the sensors are easy to install and wire. When it is necessary to replace the sensors, it is not necessary to enter the interior of the hollow pier. They can be replaced directly from the outside, avoiding the safety hazards of working in a dark and confined space.

[0047] In some embodiments, such as Figure 1As shown, the acoustic wave detection assembly 11 includes a top acoustic wave sensor group comprising a plurality of top acoustic wave sensors 111-A arranged in a ring shape at the same horizontal height, the top acoustic wave sensors 111-A are installed on the inner wall of the hollow pier 2 through a downward inclined bracket 112, the downward inclined bracket 112 is configured so that the detection direction of the top acoustic wave sensor 111-A is downward, the downward inclined bracket 112 includes a fixed plate and a downward inclined connecting rod, the fixed plate is fixedly installed on the hollow pier 2, one end of the downward inclined connecting rod is connected with the fixed plate, and the other end is connected with the top acoustic wave sensor 111-A, the downward inclined connecting rod has a downward inclined angle, and the top acoustic wave sensor 111-A is arranged obliquely on the hollow pier 2, so that the acoustic wave signals between the top acoustic wave sensor group and the middle acoustic wave sensor group can be directly received without reflection and refraction, and the contact end face of the top acoustic wave sensor 111-A is provided as an inclined surface structure, which can better fit the surface of the hollow pier 2 and facilitate the conduction of acoustic waves.

[0048] The middle acoustic wave sensor group comprises at least one ring of multiple middle acoustic wave sensors 111-B arranged in a ring shape, and the multiple middle acoustic wave sensors 111-B in the same ring are installed at the same horizontal height, and the middle acoustic wave sensors 111-B are installed on the inner wall of the hollow pier 2 through a centering bracket 113, and the centering bracket 113 is configured so that the detection direction of the middle acoustic wave sensor 111-B is transversely horizontal; the centering bracket 113 includes two groups of fixed plates and connecting rods arranged on the upper side and the lower side of the middle acoustic wave sensor, respectively, the upper side connecting rod is downwardly arranged with the fixed plate, and the lower side connecting rod is upwardly arranged with the fixed plate, so that the middle acoustic wave sensor 111-B connected with the two connecting rods is stably in contact with the hollow pier 2, and the detection direction of the middle acoustic wave sensor 111-B is transversely horizontal, and since the middle acoustic wave sensor 111-B has a larger detection angle, it can simultaneously receive and transmit acoustic wave signals of the upper part and the lower part, therefore, the transversely arranged middle acoustic wave sensor group can simultaneously receive acoustic wave signals of the top acoustic wave sensor group and the bottom acoustic wave sensor group, and can also simultaneously transmit acoustic wave signals to the top acoustic wave sensor group and the bottom acoustic wave sensor group, which is conducive to realizing detection of the overall structure of the hollow pier, including but not limited to this, for a hollow pier with a higher height, the distance between the top acoustic wave sensor 111-A and the bottom acoustic wave sensor 111-C and the middle acoustic wave sensor 111-B is farther, and due to the range limitation of the detection angle of the middle acoustic wave sensor 111-B, the acoustic wave signals of the top and bottom parts need to be received after multiple reflections or refractions, therefore, the middle acoustic wave sensor group can be provided with multiple rings of middle acoustic wave sensors 111-B at different height positions, wherein the interval height of the middle acoustic wave sensors 111-B in different rings is configured to enable adjacent rings of acoustic wave sensors 111 to receive acoustic wave signals transmitted by each other, and the two acoustic wave sensor groups of adjacent rings can be arranged on the inner side or the outer side of the hollow pier.

[0049] The bottom acoustic wave sensor group comprises a plurality of bottom acoustic wave sensors 111-C arranged in a ring shape at the same horizontal height, and the bottom acoustic wave sensors 111-C are installed on the inner wall of the hollow pier 2 through an upward inclined support 114, the upward inclined support 114 is configured such that the detection direction of the bottom acoustic wave sensor 111-C is upward, the upward inclined support 114 comprises a fixed plate and an upward inclined connecting rod, the fixed plate is fixedly installed on the hollow pier 2, one end of the upward inclined connecting rod is connected with the fixed plate, and the other end is connected with the bottom acoustic wave sensor 111-C, the upward inclined connecting rod has an upward inclined angle, and the bottom acoustic wave sensor 111-C is arranged in an inclined manner on the hollow pier 2, so that the bottom acoustic wave sensor group and the middle acoustic wave sensor group can receive or send acoustic wave signals to each other, and the contact end surface of the bottom acoustic wave sensor 111-C is provided in a beveled structure, which is also conducive to the conduction of acoustic waves.

[0050] In the detection process, the detection position of the acoustic wave sensor 111 can include the following embodiments according to the setting height, for example, in an embodiment, the top acoustic wave sensor 111-A sends an acoustic wave signal to the middle acoustic wave sensor 111-B, which can detect the structure of the hollow pier between the top acoustic wave sensor group and the middle acoustic wave sensor group; the middle acoustic wave sensor 111-B sends an acoustic wave signal to the bottom acoustic wave sensor 111-C, which can detect the structure of the hollow pier between the bottom acoustic wave sensor group and the middle acoustic wave sensor group; and at least two acoustic wave sensors 111 are controlled to work to detect the structure of the hollow pier at different heights and positions.

[0051] In another embodiment, the acoustic wave transmitter 111-1 of the acoustic wave sensor 111 emits an acoustic wave signal to the hollow pier, the acoustic wave signal reflects to generate a echo after reaching the wall surface of the hollow pier, and the echo is received by the acoustic wave receiver 111-2 of the same acoustic wave sensor 111, which can detect the internal defects of the hollow pier around the installation position of the acoustic wave sensor 111, and one acoustic wave sensor 111 is controlled to emit and receive the acoustic wave signal to realize single-point detection of the hollow pier.

[0052] In the detection process, in order to ensure the accuracy of the detection result, the above-mentioned various detection methods can be cooperated with each other to perform multiple acoustic wave detections in different directions on the same area of the hollow pier, for example, after the top acoustic wave sensor 111-A and the middle acoustic wave sensor 111-B detect that the upper structure of the hollow pier has internal defects, the acoustic wave detector 111 arranged at the upper position is controlled to perform single-point detection in sequence to determine the specific position and size of the internal defects, the detection results of multiple detection data can be verified with each other, so that the detection result is comprehensively judged, which is conducive to improving the accuracy and reliability of the detection result.

[0053] In some embodiments, asFigure 5 and Figure 6 As shown, four acoustic sensors 111 are arranged in the same circle, located in the middle of the two straight sections 21 and the two arc sections 22 of the hollow pier 2, respectively. Alternatively, the acoustic sensors 111 can also be arranged at both ends of the straight section 21 of the hollow pier 2, or six acoustic sensors 111 can be arranged in the same circle. The number and arrangement of the acoustic sensors 111 are adjusted according to the actual hollow pier structure and usage scenario. Since the hollow pier is often reinforced with steel bars to improve its overall structural strength, the dense steel bars will affect the propagation of sound waves. Therefore, when setting up the acoustic sensors 111, direct contact with the steel bars should be avoided. At the same time, the number of acoustic sensors 111 should be appropriately increased for hollow pier sections with dense steel bars to reduce the impact of the steel bars on the propagation of sound waves.

[0054] In some embodiments, such as Figure 3 and Figure 4 As shown, the sensor bracket has a mounting plate 115, and the acoustic sensor 111 is fixedly connected to one side of the mounting plate 115. The other side of the mounting plate 115 is used to contact the coupling structure 12 and the inner wall of the hollow pier. The mounting plate 115 has multiple mounting holes 115-1 for fixing to the hollow pier with threaded fasteners. The transceiver end of the acoustic sensor 111 is directly mounted on the hollow pier through the mounting plate 115, which is beneficial to the propagation of acoustic waves inside the hollow pier and improves the stability of the sensor bracket. Depending on the installation position of the acoustic sensor 111, its mounting plate 115 can be a flat plate or an arc-shaped plate. The arc-shaped plate has the same curvature as the arc-shaped segment 22 of the hollow pier 2. For example, if the acoustic sensor 111 is installed on the straight segment 21 of the hollow pier 2, its mounting plate 115 can be a flat plate, which can fit against the straight wall surface of the hollow pier 2; if the acoustic sensor 111 is installed on the arc-shaped segment 22 of the hollow pier 2, its mounting plate 115 can be an arc-shaped plate, which can fit against the arc-shaped segment 22 of the hollow pier 2. As one possible approach, since the arc angle of the arc-shaped segment at different positions of the hollow pier may vary, the arc-shaped mounting plate 115 can be set as a metal sheet structure with certain bending deformation characteristics, making the applicability of the arc-shaped mounting plate 115 better and its installation position on the hollow pier more flexible and varied.

[0055] In some embodiments, such as Figure 1 As shown, the automatic monitoring device also includes a central control platform 13, which is located at the maintenance port of the hollow pier 2. The central control platform 13 is located at the maintenance port to facilitate the equipment debugging and installation by the staff.

[0056] The central control platform 13 comprises a signal processor 131 and a controller 132, the controller 132 is arranged inside the central control platform 13, and the controller 132 and the signal processor 131 are connected with each other through wires, and the signal processor 131 and each acoustic wave sensor 111 are connected with each other through wires. The control and calculation equipment of the hollow pier automatic monitoring device is arranged inside the central control platform 13, the signal processor 131 inside the central control platform 13 is used for connecting with the acoustic wave sensor 111 on the hollow pier, transmitting and collecting the transmitted or received acoustic wave signals, the signal processor 131 can also control the acoustic wave sensors 111 at different positions to transmit or receive acoustic wave signals according to a predetermined program, and the controller 132 arranged inside the central control platform 13 is used for calculating and analyzing the detection data and results.

[0057] In some embodiments, as shown in Figure 1 The automatic monitoring device further comprises at least one image collector 14, which is configured to collect images at a set time or based on the control instruction of the automatic monitoring device. In a normal state, the image collector 14 is in a standby state to reduce unnecessary power consumption. The image collector 14 can be set to a timing mode, and when the timer reaches the set time, the image collector 14 changes from the standby state to the working state to start image detection, and after reaching the predetermined working time, the image collector 14 changes to the standby state to stop image detection. The image collector 14 can also be set to an instruction mode, and after receiving the working instruction of the automatic monitoring device, the image collector 14 changes from the standby state to the working state to perform image detection at all times until the stop instruction is received, and the image collector 14 changes to the standby state to stop working. It can be understood that the above-mentioned image collector 14 does not perform image collection work at all times, but starts to work only when the automatic monitoring device has image detection requirements, which can reduce power consumption.

[0058] In some embodiments, the number of image collectors 14 is set to one, and the image collector 14 is fixedly connected to the middle part of the top surface of the hollow pier 2, so that the detection angle of the image collector 14 can cover as large an area of the inner wall of the hollow pier 2 as possible. In addition, a wide-angle lens can be installed to improve the detection angle of the image collector 14, so as to expand the detection range of the image collector 14.

[0059] In some embodiments, the number of image collectors 14 is set to two or more, the image collectors 14 are fixedly connected with the side of the inner wall of the hollow pier 2, the installation height of each image collector 14 in the vertical direction is uniformly distributed, each image collector 14 in different horizontal directions is distributed in a staggered manner, and the plurality of image collectors 14 are arranged in a multi-level staggered manner on the inner wall of the hollow pier. By reasonably utilizing the detection visual angle of each image collector 14, the visual dead angle in the detection can be avoided, the visual full coverage of the image collector 14 on the inner wall of the hollow pier is facilitated, and the accuracy and reliability of the image collector 14 detection are improved. The above-mentioned image collector can adopt a visual monitoring camera or a smart camera, which can perform visual detection on the inner wall of the hollow pier. In use, it is selected according to the actual use scene or operation cost.
