Description

Technical Field

[0001] This utility model relates to the field of road surface inspection technology, and in particular to a road surface crack detection device and system. Background Technology

[0002] With the acceleration of urbanization, road construction and maintenance have become an important part of urban development. However, due to various factors such as foundation settlement, material aging, and vehicle load, cracks often appear on the road surface. These cracks not only affect the aesthetics of the road, but also pose a threat to driving safety.

[0003] Currently, there are two main traditional methods for detecting road surface cracks. One method involves using high-definition cameras or other image acquisition devices to capture images of the road surface, which are then manually or robotically inspected to identify cracks. However, this method is complex and requires significant time to acquire images for long-distance road surface inspections. The other method involves placing a crack detection sensor on a mobile platform, which then moves the sensor to detect road surface cracks. However, this method provides a complex road surface crack detection device, and the mobile platform typically uses a small-wheeled trolley or a walking robot with limited forward speed, resulting in low road surface crack detection efficiency.

[0004] Therefore, those skilled in the art urgently need an efficient and convenient road surface crack detection device. Utility Model Content

[0046] This embodiment employs a technical solution that places the sensor 30 for detecting road surface cracks into the accommodating space formed by the mounting base 10 and the housing 20, and fixes the device to the vehicle body via the mounting base 10. Compared with the prior art, this embodiment can perform road surface detection in real time during the movement of the vehicle body, thus improving the efficiency of road surface crack detection.

[0047] Meanwhile, in this embodiment, a vibration energy collection component is also provided in the accommodating space formed by the mounting base 10 and the housing 20. The vibration energy collection component can collect the vibration energy generated during the movement of the vehicle body and convert the vibration energy into electrical energy, which can provide additional power to the device and improve the device's endurance.

[0048] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0049] First, refer to Figure 2 As shown, the mounting base 10 is connected to the vehicle body through several bottom mounting holes 11 and fasteners. The fasteners can be countersunk screws, and threaded holes with the same thread as the countersunk screws are provided on the vehicle body, so that the mounting base 10 is fixedly installed on the vehicle body.

[0050] Secondly, refer to Figure 2 As shown, the side of the mounting base 10 is threaded to the inner wall of the housing 20, forming a receiving space inside the device, allowing the user to quickly disassemble the device and perform maintenance on the internal components. The road crack detection device also includes a baffle 28, which divides the receiving space into a first receiving space 21 and a second receiving space 22. The first receiving space 21 houses electronic components including a sensor 30, a locator 24, a wireless communication module 25, an alarm 26, and a battery pack 27. The second receiving space 22 houses a vibration energy harvesting assembly.

[0051] Furthermore, sensor 30 is used to transmit crack detection signals to the road surface and receive feedback signals indicating completion of road surface crack detection. Sensor 30 is at least one of an ultrasonic sensor, a laser interferometer, and an infrared scanner. Positioner 24 is used to acquire the location information of the road surface crack detection device. Positioner 24 is at least one of a GPS positioner and a BeiDou satellite positioner. Alarm 26 is connected to sensor 30 and is used to activate an alarm upon receiving a road surface crack signal from sensor 30. Wireless communication module 25 is connected to both sensor 30 and positioner 24. When sensor 30 detects a crack in the road surface, wireless communication module 25 sends the feedback signal from sensor 30 and the location information obtained by positioner 24 to the user terminal. Wireless communication module 25 is at least one of a Wi-Fi module, a Bluetooth module, and a LoRa (Long Range) module. The battery pack 27 is connected to the locator 24, the wireless communication module 25, the alarm 26, the sensor 30, and the piezoelectric element 42, respectively, and is used to receive and store the electrical energy generated by the piezoelectric element 42, and to provide the target voltage to the locator 24, the wireless communication module 25, the alarm 26, and the sensor 30.

[0052] Next, the housing 20 is provided with mounting holes for installing the light-transmitting cover 23. When the light-transmitting cover 23 is installed, the mounting holes are flush with the outer surface of the housing 20. Through the light-transmitting cover 23, the detection signal generated by the sensor 30 inside the device can illuminate the road surface to be detected and receive the feedback signal after the road surface detection is completed.

[0053] Then, the housing 20 is also provided with a heated demister 50 and a wiping assembly.

[0056] Furthermore, the vibrating substrate 41 is a manganese steel sheet or a fiberglass board. The vibrating substrate 41 uses materials with high toughness, such as low-carbon steel, manganese steel, and fiberglass. The low hardness and high toughness of the material ensure that the vibrating substrate 41 can withstand large vibration loads. The piezoelectric element 42 is any one of a piezoelectric ceramic sheet or a polyvinylidene fluoride sheet, and piezoelectric elements are attached to the upper and lower surfaces of the second end of each vibrating substrate 41.
