Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted radar technology and equipment, specifically to a vehicle-mounted radar for detecting road voids that is easy to assemble. Background Technology

[0002] With the rapid development of highway construction in my country, the safe operation and maintenance of road infrastructure has become an increasingly important issue in the transportation sector. Road surface defects, especially cavities, not only affect driving safety and comfort but may also lead to structural damage to the road surface, increasing the risk of traffic accidents. Traditional road inspections mainly rely on manual patrols, which are not only inefficient but also make it difficult to detect potential road surface defects in a timely manner.

[0003] To improve the scientific rigor and predictability of road maintenance, various road inspection equipment have emerged. Among them, vehicle-mounted radar inspection technology, with its advantages of non-destructive operation, high efficiency, and all-weather operation, has gradually become the mainstream technology for detecting road cavities. In recent years, vehicle-mounted inspection equipment based on ground-penetrating radar (GPR) has been widely used in the field of road cavity detection. This type of equipment can effectively identify structural anomalies and cavities under the road surface by emitting electromagnetic waves and receiving reflected signals from the underground medium.

[0004] For example, Chinese patent CN218703019U discloses a vehicle-mounted radar for detecting road voids that is easy to assemble. It includes a radar body and a detection carrier for mounting the radar body. The detection carrier includes a vehicle body, a rotating disk, a rotating assembly, a hinged seat, an electric lifting rod, a fixed disk, a mounting base, a rotating fixing frame, and two adjustment components. These components can adjust the vertical detection angle of the radar body, improving detection accuracy. However, in practical applications, the aforementioned radar has the following shortcomings: First, the device can only adjust the height and horizontal extension distance of the radar body via the electric lifting rod to detect voids in the tunnel top and sidewalls, but cannot detect the road below. Second, the device lacks an effective shock absorption structure. During vehicle operation, road bumps and vibrations may be directly transmitted to the radar body. This vibration may cause random shifts in the sampling position, resulting in uneven distribution of sampling points and reduced detection accuracy. Third, the radar body is a single, integral structure, making it difficult to flexibly adjust the number and distribution of detection components according to different road conditions and detection needs. This limits the radar's adaptability to complex road conditions and may lead to insufficient detection coverage or duplicate detection in certain areas, affecting overall detection efficiency.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in related technologies, this utility model proposes a vehicle-mounted radar for detecting road cavities that is easy to assemble, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

A rectangular radar base is fixedly installed at the bottom inner side of the mounting frame. Several first cavity detection components are arranged at equal intervals on the inner side of the rectangular radar base. A second cavity detection component is arranged between two sets of first cavity detection components. A rectangular radar top cover is provided at the top of the rectangular radar base, and several mounting components that cooperate with the rectangular radar top cover and the rectangular radar base are symmetrically arranged on both sides of the mounting frame.

[0009] Furthermore, in order to achieve a shock-absorbing structure with dual damping functions and improve the detection accuracy of the first and second void detection components, the vehicle-mounted shock-absorbing component includes a connecting plate located at the bottom of one side of the mounting bracket. A V-shaped connecting arm is provided on one side of the connecting plate. A connecting shaft is provided through the middle of the V-shaped connecting arm and the connecting plate. Both ends of the V-shaped connecting arm are provided with movable wheels. A first pin is provided through the middle of both ends of the V-shaped connecting arm. An elastic telescopic rod is sleeved on the outer side of one end of the first pin. The two sets of elastic telescopic rods are V-shaped, and a second pin is provided through one end of the elastic telescopic rod. A connecting post is fixedly provided at one end of the second pin, and the bottom end of the connecting post is fixedly connected to the mounting bracket.

[0010] Furthermore, in order to detect underground cavities in roads using ground-penetrating radar and circular probes, the bottom inner side of the rectangular radar top cover is hollow, and the top of the rectangular radar top cover is provided with an arc-shaped part, with handles extending through both sides of the top of the arc-shaped part; the top of the rectangular radar bottom shell is provided with a radar mounting slot, and the top of the radar mounting slot is provided with several equally spaced radar probe slots; the first cavity detection component and the second cavity detection component have the same structure. The first cavity detection component includes a first mounting plate located at the top of the inner side of the rectangular radar bottom shell, with support plates on both sides of the top of the first mounting plate, and a radar power supply between the two sets of support plates. A second mounting plate is located at the top of the support plates, and a ground-penetrating radar is installed at the bottom of one end of the second mounting plate. A circular probe is installed at the bottom of the ground-penetrating radar, penetrating through the first mounting plate, and a cross-shaped protective cover that cooperates with the circular probe is installed at the bottom of one end of the first mounting plate. Several cable outlet slots are provided at the top of the second mounting plate located on the ground-penetrating radar, and several cable inlets are provided at the other end of the second mounting plate located on the top of the radar power supply.

[0011] Furthermore, in order to achieve a quick-assembly fixed structure between the rectangular radar bottom shell and the rectangular radar top cover, facilitating the adjustment of the distribution and quantity of the first and second cavity detection components, the mounting component includes a snap-fit ​​groove on one side of the mounting bracket. Several equidistantly arranged fixing blocks are fixedly installed on one side of the snap-fit ​​groove. A snap-fit ​​plate is sleeved on the outside of the fixing blocks. A first locking member is fixedly connected to the rectangular radar top cover at the top of the snap-fit ​​plate, and a second locking member is fixedly connected to the rectangular radar bottom shell at the bottom of the snap-fit ​​plate. The first locking member and the second locking member have the same structure. A limiting groove that cooperates with the snap-fit ​​plate is opened at the bottom of one end of the first locking member, and an adjusting bolt is installed through the second locking member at the bottom of the other end of the first locking member.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model has a scientific and novel structure. Through the synergistic effect of the double-layer mounting frame, multiple sets of first and second cavity detection components, and vehicle-mounted shock-absorbing components, the vehicle-mounted radar can collect data more stably during operation. In addition, the design of the rectangular radar top cover, which is easy to open, allows for quick adjustment of the number and layout of detection components according to different road conditions and detection needs, thereby improving the efficiency of road cavity detection and providing a more practical technical means for road cavity detection.

[0014] 2. By setting up a first cavity detection component and a second cavity detection component, multi-directional coverage detection of underground cavities in roads is achieved. The staggered layout of multiple detection components reduces blind spots and improves the accuracy and reliability of data. At the same time, the simultaneous operation of multiple detection components greatly improves detection efficiency, enabling the detection of underground cavities in roads to be completed in a shorter time, providing data support for road maintenance and safety management.

[0015] 3. By setting up installation components and vehicle-mounted shock-absorbing components, the rectangular radar top cover and rectangular radar bottom shell are made easy to assemble and efficiently damped. The quick-release design of the installation components makes it easy to open the rectangular radar top cover to adjust the distribution and number of the first and second cavity detection components, improving the maintainability of the equipment. The dual damping function of the vehicle-mounted shock-absorbing components effectively reduces vibration during driving, ensuring that the ground-penetrating radar can collect data more stably during travel, and improving the detection accuracy of the first and second cavity detection components.

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a vehicle-mounted radar for detecting road cavities that is easy to assemble is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8 As shown, the road cavity detection vehicle-mounted radar according to an embodiment of the present invention includes a mounting frame 1, which has a double-layer structure. A vehicle body connecting triangle 2 is provided at the top center of the mounting frame 1. Vehicle anti-vibration components 3 are symmetrically provided at both ends of the mounting frame 1. A rectangular radar base shell 4 is fixedly provided at the bottom inner side of the mounting frame 1 (in addition, in specific applications, the mounting frame 1 and the rectangular radar base shell 4 are fixedly connected). A plurality of first cavity detection components 5 are arranged at equal intervals on the inner side of the rectangular radar base shell 4. A second cavity detection component 6 is provided between two sets of first cavity detection components 5. A rectangular radar top cover 7 is provided at the top of the rectangular radar base shell 4. A plurality of mounting components 8 that cooperate with the rectangular radar top cover 7 and the rectangular radar base shell 4 are symmetrically provided on both sides of the mounting frame 1.

[0030] With the help of the above-mentioned technical solution of this utility model, the structure of this utility model is scientific and novel. Through the synergistic effect of the double-layer mounting frame 1, multiple sets of first cavity detection components 5 and second cavity detection components 6 and vehicle-mounted shock-absorbing components 3, the vehicle-mounted radar can collect data more stably during the journey. In addition, the design of the rectangular radar top cover 7 which is easy to open allows for quick adjustment of the number and layout of detection components according to different road conditions and detection needs, improving the efficiency of road cavity detection and providing a more practical technical means for road cavity detection.

[0031] In one embodiment, the vehicle-mounted shock absorber 3 includes a connecting plate 301 disposed at the bottom of one side of the mounting bracket 1. A V-shaped connecting arm 302 is disposed on one side of the connecting plate 301. A connecting shaft 303 is disposed through the middle of the V-shaped connecting arm 302 and the connecting plate 301. Both ends of the V-shaped connecting arm 302 are provided with movable wheels 304 (in addition, in a specific application, a fixed shaft is disposed through the middle of the movable wheel 304 at the end of the V-shaped connecting arm 302, and the fixed shaft is connected to the V-shaped connecting arm 302 by a bearing). Both ends of the V-shaped connecting arm 302 are provided with a first pin 305. An elastic telescopic rod 306 is sleeved on the outer side of one end of the first pin 305. The two sets of elastic telescopic rods 306 are V-shaped, and a second pin 307 is provided through one end of the elastic telescopic rod 306. A connecting post 308 is fixedly provided at one end of the second pin 307, and the bottom end of the connecting post 308 is fixedly connected to the mounting frame 1, thereby forming a shockproof structure with dual shock absorption function, which improves the detection accuracy of the first cavity detection component 5 and the second cavity detection component 6.

[0032] The working principle of the vehicle-mounted shock absorption component 3 is as follows: When the vehicle encounters road bumps during driving, the moving wheel 304 first receives the impact. Through the structural design of the V-shaped connecting arm 302, the vertical impact force is decomposed into two directions. These forces are transmitted to the elastic telescopic rod 306 through the first pin 305. The elastic telescopic rod 306 uses its telescopic characteristics to perform the first stage of shock absorption. At the same time, since the two sets of elastic telescopic rods 306 are arranged in a V-shape, they can absorb vertical and horizontal vibrations simultaneously. The second pin 307 and the connecting column 308 constitute the second stage of shock absorption structure, further buffering the remaining vibrations. Finally, the vibration transmitted to the mounting frame 1 is greatly reduced, ensuring that the ground-penetrating radar 504 can continuously collect data during travel. This avoids the random shift of the sampling position caused by severe vibration, resulting in uneven distribution of sampling points. It also avoids severe vibration at the position of the circular probe 505, which causes signal strength fluctuations and affects the quality of the echo signal. This improves the detection accuracy of the first cavity detection component 5 and the second cavity detection component 6.

[0033] In one embodiment, the first cavity detection component 5 includes a first mounting plate 501 disposed at the top inner side of the rectangular radar housing 4 (in addition, in specific applications, the bottom end of the first mounting plate 501 is connected to the rectangular radar housing 4 by bolts). Support plates 502 are disposed on both sides of the top end of the first mounting plate 501, and a radar power supply is disposed between the two sets of support plates 502. A second mounting plate 503 is disposed at the top end of the support plate 502, and a ground-penetrating radar 504 is disposed at the bottom of one end of the second mounting plate 503. The bottom end of the ground-penetrating radar 504 extends through... A circular probe 505 is provided at one end of the first mounting plate 501, and a cross-shaped protective cover 506 that cooperates with the circular probe 505 is provided at the bottom of one end of the first mounting plate 501 (in addition, in specific applications, the cross-shaped protective cover 506 is placed in the radar probe slot 402). A number of cable outlet slots 507 are opened at one end of the second mounting plate 503 located at the top of the ground penetrating radar 504, and a number of cable inlets 508 are opened at the other end of the second mounting plate 503 located at the top of the radar power supply. Thus, the detection of underground cavities in the road can be achieved through the ground penetrating radar 504 and the circular probe 505.

[0034] The working principle of the first cavity detection component 5 is as follows: The first mounting plate 501 is fixed to the inner top of the rectangular radar base 4 with bolts to ensure the stability of the overall structure. The ground-penetrating radar 504 is mounted on the second mounting plate 503. The probe 505 extends into the radar probe slot 402 through the first mounting plate 501. The cross-shaped protective cover 506 protects the circular probe 505. The radar power supply is installed between the support plates 502 and supplies power to the ground-penetrating radar 504 through the inlet hole 508 and the outlet slot 507. The ground-penetrating radar 504 emits radar waves vertically towards the ground through the circular probe 505. The circular probe 505 receives the reflected signals. The radar waves penetrate the ground and are reflected when they encounter abnormal structures such as cavities. The circular probe 505 captures these reflected signals. The ground-penetrating radar 504 converts the received signals into data, analyzes them through the built-in processing system, and transmits them to external devices for further processing and display via wireless signals.

[0035] The first cavity detection component 5 and the second cavity detection component 6 have the same structure and the same working principle.

[0036] Furthermore, in specific applications, this embodiment sets up five first cavity detection components 5 and four second cavity detection components 6, which are staggered inside the rectangular radar base shell 4. Through the staggered layout of multiple detection components, all-round coverage detection of underground cavities in the road is achieved, reducing blind spots. The data collected by the detection components at different locations can complement each other, improving the accuracy and reliability of the overall data. Moreover, the simultaneous operation of multiple detection components improves detection efficiency, enabling the detection of large-area underground cavities in the road in a short time. In addition, the distribution of multiple detection components helps to distribute the weight of the equipment and enhance the stability of the overall structure of the vehicle-mounted radar.

[0037] In one embodiment, the bottom inner side of the rectangular radar top cover 7 is hollow, and the top of the rectangular radar top cover 7 is provided with an arc-shaped part 701. Handles 702 are provided through both sides of the top of the arc-shaped part 701. The top of the rectangular radar bottom shell 4 is provided with a radar mounting groove 401, and the top of the radar mounting groove 401 is provided with a plurality of equally spaced radar probe grooves 402.

[0038] In one embodiment, the mounting assembly 8 includes a snap-fit ​​groove 801 formed on one side of the mounting bracket 1. A plurality of equidistantly arranged fixing blocks 802 are fixedly disposed on one side of the snap-fit ​​groove 801. A snap-fit ​​plate 803 is sleeved on the outer side of each fixing block 802 (in addition, in specific applications, a plurality of through holes cooperating with the fixing blocks 802 are formed on one side of the snap-fit ​​plate 803). A first locking member 804, which is fixedly connected to the rectangular radar top cover 7, is provided at the top of the snap-fit ​​plate 803, and a second locking member 804, which is fixedly connected to the rectangular radar bottom shell 4, is provided at the bottom of the snap-fit ​​plate 803. Locking component 805, first locking component 804 and second locking component 805 have the same structure (in addition, in specific applications, first locking component 804 and second locking component 805 are symmetrically arranged). The bottom of one end of the first locking component 804 is provided with a limiting groove that cooperates with the snap-fit ​​plate 803. The bottom of the other end of the first locking component 804 is provided with an adjusting bolt 806 that passes through the second locking component 805. Thus, the rectangular radar bottom shell 4 and the rectangular radar top cover 7 form a fixed structure that can be quickly assembled, which facilitates the adjustment of the distribution and number of the first cavity detection component 5 and the second cavity detection component 6.

[0039] The working principle of mounting component 8 is as follows: The rectangular radar base 4 is fixedly connected to the mounting bracket 1. Mounting component 8 is used to fix the rectangular radar top cover 7 and the rectangular radar base 4. When it is necessary to open the rectangular radar top cover 7, first loosen the adjusting bolt 806, and then lift the rectangular radar top cover 7 using the handle 702. At this time, the first locking member 804 and the second locking member 805 separate, and the snap-fit ​​plate 803 fitted outside the fixing block 802 can be taken out. Then, the rectangular radar top cover 7 is moved horizontally from the middle of the double-layer structure of the mounting bracket 1, so that the distribution of the first cavity detection component 5 and the second cavity detection component 6 inside the rectangular radar base 4 can be adjusted. When closing, the operation is performed in the reverse order. The first locking member 804 and the second locking member 805 are fixed in conjunction with the snap-fit ​​plate 803, and the adjusting bolt 806 is locked to ensure a tight connection and stability between the rectangular radar top cover 7 and the rectangular radar base 4.

[0040] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0041] In practical applications, this road cavity detection vehicle-mounted radar can be installed on a dedicated inspection vehicle. First, the mounting bracket 1 is fixed to the bottom rear of the inspection vehicle via the vehicle-mounted triangular bracket 2. At the start of the inspection, the operator can open the rectangular radar top cover 7 via the mounting component 8, depending on road conditions, and configure an appropriate number of first cavity detection components 5 and second cavity detection components 6. Then, during vehicle operation, the dual shock absorption function of the vehicle-mounted anti-vibration component 3 ensures inspection stability. Simultaneously, the ground-penetrating radar 504 emits electromagnetic waves through the circular probe 505 and receives reflected signals from underground. With multiple detection components working simultaneously, comprehensive road coverage detection is achieved. The collected data, after processing, can visually display the distribution of cavities beneath the road, providing accurate information for road maintenance.
