Description

Technical Field

[0001] The utility model relates to the technical field of ground penetrating radar, in particular to a fixing device for a ground penetrating radar. Background Art

[0002] Ground Penetrating Radar (GPR) is a non-invasive geophysical exploration technology used to detect underground structures and material distribution. It transmits high-frequency electromagnetic waves into the ground and uses the received reflected signals to delineate subsurface targets and layered structures. Fixed GPR is typically used to detect underground conditions at specific locations, such as bridge foundations, cracks within concrete, or critical points in building structures. In this case, the equipment is mounted on a bracket or platform, with the transmitting and receiving antennas kept stable. Precise scanning is achieved by adjusting the angle and position of the antennas, ensuring high resolution and accuracy in the detection results.

[0003] Since ground-penetrating radar relies entirely on the stability of the mounting platform when in a fixed state, any slight environmental vibration or external interference will directly affect the accuracy of the detection results. If the fixed equipment lacks a shock absorption system, the signal quality of the ground-penetrating radar may be disturbed when subjected to external vibrations, resulting in noise or distortion in the collected data. This problem is particularly evident in high-precision detection scenarios. In addition, fixed equipment cannot actively adapt to the frequency and intensity of external vibrations and is easily disturbed by external factors such as ground vibration and mechanical equipment operation during long-term monitoring, ultimately reducing the reliability of the detection results.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0024] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. By referring to these contents, ordinary technicians in this field 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 generally used to represent similar components.

[0025] According to an embodiment of the present utility model, a fixing device for a ground penetrating radar is provided.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 7 As shown, a fixing device for a ground penetrating radar according to an embodiment of the utility model includes a traction bracket 1, a protective shell 2 is provided inside the traction bracket 1, a ground penetrating radar body 3 is provided in the middle of the protective shell 2, a fixing component 4 is provided outside the ground penetrating radar body 3, a bottom support plate 5 is provided at the bottom end of the protective shell 2, and an opening and closing component 6 that cooperates with the ground penetrating radar body 3 is provided in the middle of the bottom support plate 5.

[0027] Specifically, the GPR body 3 is primarily composed of the following components: a transmitting antenna, a receiving antenna, a signal processing module, a control unit, and a power supply module. The transmitting antenna converts electrical signals into high-frequency electromagnetic waves and radiates them underground. The receiving antenna receives echo signals returning from underground and converts them into electrical signals. The signal processing module, which includes filters, amplifiers, and a digital signal processing unit, samples, amplifies, removes noise, and processes the echo signals for imaging. The control unit manages the timing of signal transmission and reception, ensuring synchronized operation of the system. The power supply module provides power to all components of the device.

[0028] Ground-penetrating radar (GPR) is based on the transmission, propagation, reflection, and reception of high-frequency electromagnetic waves. A transmitting antenna emits high-frequency electromagnetic waves into the ground. When these waves encounter discontinuous interfaces between different underground media, they are reflected and transmitted. The intensity and time delay of the reflected waves depend on the electromagnetic properties of the media, as well as the depth and shape of the target. A receiving antenna receives the reflected waves, converts them into electrical signals, and extracts useful feature information from them. This is a well-known technique and will not be elaborated on here.

[0029] Specifically, such as Figure 7 As shown, the traction bracket 1 includes a traction frame body 101 and several Mecanum wheels 102 arranged on both sides thereof, and the traction bracket 1 is connected to the tractor 7 through a connecting assembly on the top. By connecting with the tractor 7, the traction bracket 1 can achieve rapid movement with the help of the power of the tractor 7, so that the ground penetrating radar body 3 can cover a larger detection area. This movement method not only reduces the workload of manual pushing and pulling, but also improves the movement efficiency of the radar in large areas of complex terrain.

[0030] In one embodiment, for the above-mentioned protective shell 2, a radar signal radiation slot 201 is provided at the bottom end of the protective shell 2 to cooperate with the opening and closing component 6, thereby providing a dedicated channel for the signal transmission of the ground penetrating radar body. Since the ground penetrating radar body 3 needs to send electromagnetic wave signals underground and receive echoes, the signal radiation slot is used to ensure that the signal transmission direction is clearer, thereby enhancing the signal strength and focusing ability.

[0031] In one embodiment, for the above-mentioned fixing component 4, the fixing component 4 includes a base plate 401 arranged at the bottom end of the protective shell 2, a placement groove 402 matched with the ground penetrating radar body 3 is provided in the middle of the base plate 401, a cylinder 403 is provided around the top of the base plate 401, an abutment plate 405 is provided at the output end of the cylinder 403, a buffer component 404 is provided between the abutment plate 405 and the ground penetrating radar body 3, and the buffer component 404 includes a buffer pad 4041 arranged between the abutment plate 405 and the ground penetrating radar body 3, a plurality of buffer cavities 4042 are opened inside the buffer pad 4041, an air bag 4043 is provided inside the buffer cavity 4042, a pad 4044 is provided at the top of the air bag 4043, a buffer plate 4045 matched with the ground penetrating radar body 3 is provided on the top of the pad 4044, and the buffer plate 4045 and the pad 4044 are provided with a buffer plate 4045 matched with the ground penetrating radar body 3, and the buffer plate 4045 and the pad 4044 are provided with a buffer plate 4045. A compression spring 4046 is arranged between the adjacent buffer cavities 4042 located in the same horizontal direction, and a through hole 4047 is opened through the adjacent buffer cavities 4042, and an air pipe 4048 is inserted into the through hole 4047, so that the ground penetrating radar body 3 can be firmly installed to avoid loosening problems caused by external forces during operation. The cylinder 403 and the abutment plate 405 at its output end can adjust the installation pressure of the ground penetrating radar body 3 as needed to ensure that the ground penetrating radar body 3 can maintain the best stability under different working conditions. The buffer structure is formed by the buffer pad 4041, buffer cavity 4042, airbag 4043, pad 4044, buffer plate 4045 and compression spring 4046 in the buffer assembly 404, which can effectively absorb and disperse vibration and impact force from the outside, protect the ground penetrating radar body 3 from damage, and thus improve the overall durability of the device.

[0032] Specifically, the working principle of the fixing component 4 includes: when the ground penetrating radar body 3 needs to be fixed, the cylinder 403 is started by the external controller, and the output end of the cylinder 403 drives the abutment plate 405 to move in the direction of the ground penetrating radar body 3, and the ground penetrating radar body 3 is fixed by the cooperation of several abutment plates 405. If the ground penetrating radar body 3 is subjected to external vibration or impact, the ground penetrating radar body 3 contacts the buffer plate 4045 on one side of the abutment plate 405, and the buffer plate 4045 is squeezed and compressed. Spring 4046 is compressed, and the pad 4044 is squeezed by compressing the spring 4046, and the airbag 4043 is squeezed by the pad 4044. Since several airbags 4043 are connected by the air pipe 4048, the gas in the airbag 4043 is dispersed to other connected airbags 4043 through the air pipe 4048, forming a multi-stage buffering process, which can avoid the impact force being concentrated on a single part to cause damage, thereby achieving uniform distribution of pressure, and further protecting the ground penetrating radar body 3 from damage by concentrated impact force by reducing the force intensity per unit area.

[0033] In one embodiment, for the above-mentioned opening and closing component 6, the opening and closing component 6 includes a plurality of connecting shafts 601 arranged inside the bottom support plate 5, a first driving ring 602 is arranged on the outer circumference of the connecting shafts 601 located in the same horizontal direction, a second driving ring 603 is arranged on the outer circumference of two of the connecting shafts 601 located in the same longitudinal direction, a first driving belt 604 is arranged between two adjacent first driving rings 602 located in the same horizontal direction, a second driving belt 605 is arranged between the second driving rings 603, a connecting rod 606 is arranged between the two first driving belts 604, and a telescopic plate 607 is arranged on one side of the connecting rod 606. A fixing rod 608 is provided on the side of 607 away from the connecting rod 606, and a toggle rod 609 is provided on the outside of the second driving belt 605, so as to realize the controllable opening and closing of the radar signal radiation slot 201, and prevent dust, mud, moisture or other external impurities from entering the protective shell 2 through the radar signal radiation slot 201 in the non-working state, thereby effectively reducing the pollution and loss risks in the ground penetrating radar body 3, reducing the maintenance frequency, and extending the service life of the ground penetrating radar body. At the same time, it prevents the intrusion of external pollutants from interfering with the fixed component 4, such as dust accumulation, rust or aging of components, thereby extending the service life of the fixed component 4.

[0034] Specifically, the working principle of the opening and closing component 6 includes: driving the movement of the second drive belt 605 by the toggle rod 609, and the second drive belt 605 can drive the second drive ring 603 located outside the circumference of the connecting shaft 601 to rotate while moving, and the connecting shaft 601 is driven to rotate by the second drive ring 603, and the first drive ring 602 is driven to rotate while the connecting shaft 601 rotates. The two groups of first drive rings 602 located in the same horizontal direction drive the first drive belt 604 to move, and during the movement of the first drive belt 604, the connecting rod 606 and the telescopic plate on one side are driven to fold toward the direction of the fixed rod 608 (the fixed rod 608 is fixed by bolts), so that the electromagnetic wave signal emitted by the ground penetrating radar body 3 can be transmitted to the underground through the signal radiation slot, ensuring that the signal transmission direction is clearer.

[0035] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0036] In actual use, the ground-penetrating radar body 3 is first fixed using the fixing assembly 4 (the working principle of the fixing assembly 4 is described above). The traction support is then driven by the power of the tractor 7 to move rapidly, enabling the device to cover a wider detection area, while reducing the workload of manual pushing and pulling and improving movement efficiency in complex terrain. During the movement of the traction support, the ground-penetrating radar body, located in the middle of the protective shell, transmits electromagnetic wave signals into the ground. When the electromagnetic wave signals encounter the discontinuous interface between different underground media, they are reflected, and detection results are extracted based on the reflected signals. Simultaneously, during movement, the buffer assembly 404 effectively absorbs and disperses external vibrations and impact forces, protecting the ground-penetrating radar body 3 from damage. When the ground-penetrating radar body 3 is not in use, the radar signal radiation slot 201 is closed using the opening and closing assembly 6 (the working principle of the opening and closing assembly 6 is described above). This prevents dust, sand, moisture, or other external impurities from entering the protective shell 2 through the radar signal radiation slot 201 when not in use, thereby effectively extending the service life of the ground-penetrating radar body 3.

[0037] In summary, with the aid of the above technical solution of the present invention, the present invention can achieve a stable installation of the ground penetrating radar body 3 by setting a fixing component 4, avoiding the loosening problem caused by external force during operation, and the cylinder 403 and the abutment plate 405 at its output end can adjust the installation pressure of the ground penetrating radar body 3 as needed, ensuring that the ground penetrating radar body 3 can maintain the best stable state under different working conditions, and the buffer structure is formed by the buffer pad 4041, buffer cavity 4042, airbag 4043, pad 4044, buffer plate 4045 and compression spring 4046 in the buffer component 404, which can effectively absorb and disperse the external force. The vibration and impact of the world can protect the ground penetrating radar body 3 from damage, thereby improving the overall durability of the device; the utility model can realize the controllable opening and closing of the radar signal radiation slot 201 by setting the opening and closing component 6, thereby preventing dust, mud, moisture or other external impurities from entering the protective shell 2 through the radar signal radiation slot 201 in the non-working state, thereby effectively reducing the pollution and loss risks in the ground penetrating radar body 3, reducing the maintenance frequency, and extending the service life of the ground penetrating radar body. At the same time, it avoids the intrusion of external pollutants to interfere with the fixing component 4, such as dust accumulation, rust or component aging, thereby extending the service life of the fixing component 4.
