Description

Technical Field

[0001] The utility model belongs to the technical field of ground penetrating radar, and in particular relates to a ground penetrating radar ranging auxiliary device. Background Art

[0002] Ground penetrating radar is a type of radar. Traditional ground penetrating radars are relatively large in size and are basically equipped with corresponding driving carts for auxiliary carrying and measurement, so the ranging function is integrated into the cart. At present, ground penetrating radars have the following defects in actual use:

[0003] 1. The ground penetrating radar detection method mainly collects distance measurement data through the encoder distance measurement module integrated with the driving trolley. The overall volume and weight of the driving trolley and the ground penetrating radar host are relatively large, which is only suitable for the detection of relatively flat horizontal roads. It cannot perform good control detection on non-horizontal or non-relatively regular planes, and cannot ensure the accuracy of data and the convenience of detection;

[0004] 2. The ground penetrating radar driven by a trolley requires the main unit of the ground penetrating radar to maintain a certain height distance from the ground, otherwise it cannot move forward or backward stably. The fit between the ground penetrating radar and the ground is related to the detection effect. The closer it fits the ground, the more effective the detection effect will be. However, the ground penetrating radar currently driven by a trolley cannot achieve a complete fit between the bottom and the ground, so the detection performance of the ground penetrating radar cannot reach the best;

[0005] 3. The size and weight of ground penetrating radar are relatively heavy. In order to support and bear the main unit in different scenarios, the designed driving trolley needs to increase the amount of material used in the structure to ensure the stability and reliability of the support. The large amount of material attached to the periphery of the main unit will cause the reflection of the radar signal, thus affecting the detection effect.

[0006] In order to solve the problem that ground penetrating radar cannot detect certain scenes well and stably, we provide a ground penetrating radar ranging auxiliary device based on actual on-site detection experience and engineering detection feedback. Utility Model Content

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0027] Combination Figures 1 to 3 As shown, this embodiment provides a ground penetrating radar ranging auxiliary device, which includes a radar body 10, a mounting part 20, a driving part 30 and a shock absorbing part 50. The mounting part 20 installs the device on the radar body 10, the driving part 30 pulls the radar body 10 to move, and the shock absorbing part 50 can automatically adjust according to the situation of the ground penetrating radar detection plane.

[0028] In this embodiment, one end of the mounting portion 20 is nested on the radar body 10. The mounting portion 20 is a U-shaped mounting plate. The opening of the mounting portion 20 corresponds to the position of the radar body 10. The material of the mounting portion 20 in this embodiment is the same as that of the radar body 10, thereby reducing the signal reflection effect of the radar body 10 and ensuring that the radar body 10 performs stable signal reception.

[0029] Furthermore, the driving part 30 is connected to the mounting part 20 through the connecting part 40. The driving part 30 includes a driving wheel 31 and an encoder 32. The driving wheel 31 is provided with a rotating shaft 60. The encoder 32 is installed on the rotating shaft 60 and rotates synchronously with the driving wheel 31. The driving wheel 31 and the encoder 32 move synchronously, and can transmit the sampled data to the radar body 10 in real time, thereby ensuring the stability of the radar receiving data.

[0030] Specifically, both ends of the driving wheel 31 are connected to the mounting portion 20 via the connecting portions 40 . The two connecting portions 40 can enable the driving wheel 31 to move stably, thereby stably driving the radar body 10 .

[0031] In this embodiment, there are two groups of shock absorbing parts 50 and they are located at both ends of the rotating shaft 60. The shock absorbing parts 50 include two spaced apart limiting plates 51, which are arranged on the rotating shaft 60. A shock absorbing cavity 41 is provided at the bottom of the connecting part 40. The end of the rotating shaft 60 is located in the shock absorbing cavity 41 and vibrates along the length direction of the shock absorbing cavity 41. When the driving wheel 31 rotates, the rotating shaft 60 will vibrate in the shock absorbing cavity 41, and the limiting plates 51 can limit the rotating shaft 60, thereby performing real-time shock absorption on the driving wheel 31 in motion. It can automatically adjust according to the situation of the detection plane of the ground penetrating radar to ensure that the wheel is completely in contact with the plane during the detection process, so that the detected data is more accurate and stable.

[0032] Specifically, the limiting plates 51 are located on both sides of the shock absorbing cavity 41 to reduce the shock of the driving part 30 in motion.

[0033] In summary, the ground penetrating radar ranging auxiliary device of this embodiment is composed of a driving wheel 31 and an encoder 32 that rolls in coordination, and can transmit the sampled data to the ground penetrating radar. Both ends of the driving part 30 are supported and installed by the connecting part 40, so that the forces on both ends of the driving part 30 are evenly distributed and the support balance is maintained. In addition, the existence of the shock absorbing part 50 can automatically adjust according to the situation of the ground penetrating radar detection plane, ensuring that the wheels are completely in contact with the plane during the detection process, making the detected data more accurate and stable.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
