Description

Technical Field

[0001] This utility model relates to the field of bridge seepage detection technology, and in particular to a bridge seepage detection device. Background Technology

[0002] As an important component of transportation infrastructure, the safety and durability of bridges are of paramount importance. Water seepage is one of the key factors affecting the structural safety of bridges. Long-term water seepage can lead to corrosion of the steel bars inside the bridge and a reduction in the strength of the concrete, thereby shortening the service life of the bridge and even causing safety accidents. Therefore, accurate and efficient detection of water seepage in bridges is of great significance for bridge maintenance and management.

[0003] Traditional bridge seepage detection devices have revealed many problems in practical applications. In terms of detection area and flexibility, traditional equipment usually needs to be fixed at a specific location on the bridge, and the detection range is extremely limited. It is difficult to conduct comprehensive detection of a large area of ​​the bridge structure. For long or complex bridges, the equipment often needs to be installed and disassembled multiple times, which consumes a lot of time and manpower, and it is difficult to flexibly meet different detection needs. Utility Model Content

[0004] To overcome the problems of existing bridge seepage detection devices, which typically require fixing to the bridge, resulting in a small detection area, inflexible detection, high installation and maintenance costs, and low detection accuracy, this utility model provides a bridge seepage detection device.

[0005] The technical solution is as follows: A bridge seepage detection device includes a seepage detection component, an ultrasonic transmitting component, and a handheld component; the ultrasonic transmitting component is located at the rear end of the seepage detection component; the handheld component is located at the lower end of the seepage detection component; the seepage detection component includes a detection housing, an ultrasonic signal receiver, a first signal transmission protection panel, and an information processing module; the ultrasonic transmitting component includes an ultrasonic generator and a second signal transmission protection panel; the handheld component includes a handheld stick and a battery.

[0006] Furthermore, an ultrasonic signal receiver is installed inside the detection housing; a first signal transmission protection panel is installed on the upper surface of the ultrasonic signal receiver; the first signal transmission protection panel is sealed to the opening on the upper surface of the detection housing; and the first signal transmission protection panel is fixedly connected to the upper surface of the ultrasonic signal receiver.

[0007] Furthermore, an information processing module is provided at the lower end of the ultrasonic signal receiver, and the outer shell of the information processing module is fixedly connected to the inner wall of the detection shell, and the information processing module is connected to the ultrasonic signal receiver for information transmission.

[0008] Furthermore, an ultrasonic generator is located behind the ultrasonic signal receiver, and the ultrasonic generator is fixedly connected through the inside of the detection housing, and three ultrasonic generators are provided.

[0009] Furthermore, a second signal transmission protection panel is provided on the upper surface of the ultrasonic generator, and the second signal transmission protection panel is sealed to the opening on the upper surface of the detection housing, and the second signal transmission protection panel is fixedly connected to the upper surface of the ultrasonic generator.

[0010] Furthermore, a hand-held lever is provided on the lower end face of the detection housing, and the hand-held lever is fixedly connected to the detection housing.

[0011] Furthermore, a battery is installed inside the handheld stick, and the battery powers the electrical equipment inside the detection housing.

[0012] The beneficial effects are as follows: This invention generates high-frequency mechanical vibration waves through an ultrasonic generator. After emission, these ultrasonic waves first penetrate a second signal transmission protection panel. This panel is made of a special material with high strength and matching acoustic impedance, which effectively reduces energy loss during transmission and ensures high-fidelity signal transmission. After passing through the panel, the ultrasonic waves enter an ultrasonic coupling agent layer coated on its surface. The coupling agent fills tiny gaps, eliminating acoustic impedance differences caused by air layers, thus creating a continuous and efficient propagation channel for the ultrasonic waves, allowing them to smoothly enter the bridge structure. When the ultrasonic waves propagate within the bridge structure, if they encounter gaps where water seeps in, the significant difference in acoustic impedance between water and the bridge building materials causes reflection at the interface of the seepage gap. This is based on the acoustic principle that when the ultrasonic propagation medium changes, some of the sound wave energy propagates in the opposite direction. The reflected ultrasonic waves carry information about the internal gaps and seepage conditions of the bridge structure. They then penetrate the first signal transmission protection panel. The ultrasonic signal receiver uses a highly sensitive piezoelectric conversion element. When it receives the reflected ultrasonic signal, it can quickly convert it into an electrical signal. This conversion process is based on the piezoelectric effect, which efficiently converts the mechanical vibration energy of the ultrasonic wave into an electrical signal for subsequent processing. The generated electrical signal is then transmitted to the information processing module. Through a series of processes such as filtering, amplification, and spectrum analysis of the real-time monitored ultrasonic electrical signal, key characteristic parameters in the signal are extracted, such as the intensity of the reflected wave, propagation time, and frequency changes. Based on these parameters, combined with the design parameters of the bridge structure and historical detection data, the information processing module can accurately determine whether there is a seepage problem in the bridge in the detection area. Compared with traditional detection methods, this significantly improves the efficiency and accuracy of bridge seepage detection.

[0013] By incorporating a handheld component, the handheld handle makes it easy for testers to carry the equipment by hand, improving the ease of transport. The battery inside the handheld handle provides power to the water seepage detection component, effectively reducing the equipment's dependence on the power grid and improving its mobility.

The seepage detection component 1 includes a detection housing 101, an ultrasonic signal receiver 102, a first signal transmission protection panel 103, and an information processing module 104. The ultrasonic transmitting component 2 includes an ultrasonic generator 201 and a second signal transmission protection panel 202. The handheld component 3 includes a handheld stick 301 and a battery 302.

[0024] An information processing module 104 is provided at the lower end of the ultrasonic signal receiver 102, and the outer shell of the information processing module 104 is fixedly connected to the inner wall of the detection housing 101, and the information processing module 104 is connected to the ultrasonic signal receiver 102 for information transmission.

[0025] An ultrasonic generator 201 is provided behind the ultrasonic signal receiver 102, and the ultrasonic generator 201 is fixedly connected through the inside of the detection housing 101, and three ultrasonic generators 201 are provided.

[0026] The upper surface of the ultrasonic generator 201 is provided with a second signal transmission protection panel 202, and the second signal transmission protection panel 202 is sealed to the opening on the upper surface of the detection housing 101, and the second signal transmission protection panel 202 is fixedly connected to the upper surface of the ultrasonic generator 201.

[0027] High-frequency mechanical vibration waves are generated by the ultrasonic generator 201. After emission, these ultrasonic waves first penetrate the second signal transmission protection panel 202. This panel is made of a special material with high strength and acoustic impedance matching, which can effectively reduce the energy loss of ultrasonic waves during transmission and ensure that the signal passes through with high fidelity. After passing through the panel, the ultrasonic waves enter the ultrasonic coupling agent layer coated on its surface. The coupling agent fills the tiny gaps and eliminates the acoustic impedance difference caused by the air layer, creating a continuous and efficient propagation channel for the ultrasonic waves, allowing them to smoothly enter the interior of the bridge structure. When the ultrasonic waves propagate in the bridge structure, if they encounter gaps where water seeps in, due to the significant difference in acoustic impedance between water and bridge building materials, the ultrasonic waves will be reflected at the interface of the seepage gap. This is based on the acoustic principle that when the ultrasonic propagation medium changes, some of the sound wave energy will propagate in the opposite direction, and the reflected ultrasonic waves... Carrying information about the internal gaps and seepage conditions of the bridge structure, the ultrasonic signal receiver 102, which uses a highly sensitive piezoelectric conversion element, transmits the signal through the first signal transmission protection panel 103. Upon receiving the reflected ultrasonic signal, it can quickly convert it into an electrical signal. This conversion process is based on the piezoelectric effect, which efficiently converts the mechanical vibration energy of the ultrasonic wave into an electrical signal for easy subsequent processing. The generated electrical signal is then transmitted to the information processing module 104. Through a series of processes such as filtering, amplification, and spectrum analysis of the real-time monitored ultrasonic electrical signal, key characteristic parameters in the signal, such as the intensity of the reflected wave, propagation time, and frequency changes, are extracted. Based on these parameters, combined with the design parameters of the bridge structure and historical detection data, the information processing module can accurately determine whether there is a seepage problem in the bridge in the detection area. Compared with traditional detection methods, this significantly improves the efficiency and accuracy of bridge seepage detection.

The battery 302 inside the handheld lever 301 provides power to the electrical equipment of the water seepage detection component 1, effectively reducing the equipment's dependence on the power grid and improving the convenience of moving and working the equipment.
