Description

Technical Field

[0001] This utility model relates to the field of highway traffic safety settings, and in particular to a support device for improving the accuracy of detecting the burial depth of steel guardrail posts. Background Technology

[0002] As the main body that withstands the impact of vehicles going off the road, the burial depth of highway guardrail posts directly affects their protective capability. Currently, the burial depth of posts is usually detected using impact elastic waves as the medium. The impact elastic wave method for measuring post burial depth generally involves attaching sensors to the outer surface of the post to collect and receive signals. However, steel guardrail posts have a special hollow structure with a large specific surface area. When using the impact elastic wave method to detect their burial depth, not only is the vibration residual time long, but the sound generated by the impact also resonates with the cavity, causing the excitation signal to decay more slowly, affecting signal recognition. Furthermore, accurately identifying the reflected signal from a signal with a long residual vibration time and interference from noise sources is extremely difficult. Therefore, reducing the influence of the self-vibration signal in the elastic wave on the reflected signal is of great significance for improving the accuracy of post burial depth detection.

Detailed Implementation

[0025] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 As shown in the figure, this embodiment discloses a support device for improving the accuracy of detecting the burial depth of steel guardrail posts. The device includes a support body 1, a sensor support 2 at one end of the support body 1, and a soil-breaking component 3 and a sensor 4 mounted on the sensor support 2. The sensor 4 is an acceleration sensor.

[0027] like Figure 2 As shown, the sensor support 2 includes a mounting part 201, and the soil breaking component 3 and the sensor 4 are both mounted on the mounting part 201; a connecting part 202 is integrally formed on the mounting part 201, and the connecting part 202 is detachably connected to the end of the support body 1.

[0028] In this embodiment, as a way to detach the connecting part 202 from the bracket body 1, the bracket body 1 is provided with a support mounting hole 101 at its end, and the connecting part 202 is connected to the support mounting hole 101 through a threaded structure.

[0029] The sensor 4 is disposed on the connecting part 202 and is hidden in the support mounting hole 101. Specifically, the end of the connecting part 202 is provided with a sensor mounting hole 203, and the sensor 4 is connected to the sensor mounting hole 203 by a threaded structure.

[0030] like Figure 2 and 3 As shown, in this embodiment, the connecting part 202 and the ground-breaking component 3 are located at both ends of the mounting part 201, and both the connecting part 202 and the ground-breaking component 3 are arranged perpendicular to the mounting part 201. The ground-breaking component 3 is disposed on the mounting part 201 and faces away from the connecting part 202. The ground-breaking component 3 is provided with a mounting hole 301, which is connected to the mounting part 201 by screws.

[0031] The soil-breaking component 3 is stepped, and the front end of the soil-breaking component 3 is designed with a sloping structure, which can help the entire device penetrate to the bottom along the inner surface of the column, reducing the secondary vibration signals received by the sensor that will cause interference.

[0032] like Figure 4 As shown, in this embodiment, the interior of the bracket body 1 has a through-hole 102 along the axial direction, which communicates with the mounting hole 101 of the support. This design allows the signal line of the sensor 4 to be routed through the hollow structure inside the entire bracket body 1, effectively reducing the tangling of the signal line.

[0033] like Figure 4 As shown, in this embodiment, the bracket body 1 has a removable rear cover 5 at one end away from the support mounting hole 101. A wire outlet hole 501 is provided on the rear cover 5, through which the signal wire connected to the sensor 4 can pass.

[0034] In this embodiment, as a way to detach and connect the back cover 5 to the bracket body 1, the bracket body 1 is provided with a back cover mounting hole 103 at the end away from the support mounting hole 101, and the back cover 5 is threadedly connected to the back cover mounting hole 103.

[0035] In this embodiment, the main body 1 of the support is a rod-shaped structure.

[0036] like Figure 5 As shown, the usage process of this utility model is as follows:

[0037] The soil-breaking component 3 extends to the bottom of the inner surface of the column. The soil-breaking component 3 and the sensor support 2 are not on the same plane. The soil-breaking component 3 is slightly inward, so that the sensor support 2 can better contact the inner surface of the column and receive vibration signals.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
