Description

Technical Field

[0002] Ground penetrating radar (GPR) is a non-destructive detection technology that uses high-frequency electromagnetic waves to detect the distribution of underground media. Its working principle is to transmit high-frequency electromagnetic waves into the ground through a transmitting antenna. When the electromagnetic waves encounter the interface of different media, they will be reflected and refracted. The receiving antenna receives these reflected echoes, and after signal processing, an image is formed, thereby realizing the detection, identification, and location of underground targets. A portable vehicle frame refers to a frame structure designed for carrying and installing GPR equipment.

[0003] The existing portable frames of some ground-penetrating radars are prone to damage to the bottom of the radar when moving on uneven ground, due to the close proximity of the radar to the ground.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a portable vehicle frame for a ground-penetrating radar. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A portable frame for a ground-penetrating radar includes a ground-penetrating radar body 1, a set of movable wheels 2 on the surface of the ground-penetrating radar body 1, a folding frame 3 on the surface of the ground-penetrating radar body 1, and a lifting mechanism 4 at the bottom of the ground-penetrating radar body 1.

[0026] The lifting mechanism 4 includes a housing 401, which is disposed on the surface of the ground-penetrating radar body 1. Two dual-axis motors 402 are fixedly connected to the inner wall of the housing 401. Each of the two output ends of the two dual-axis motors 402 is fixedly connected to a transmission rod 403. One end of the transmission rod 403 is rotatably connected to the inner wall of the housing 401, and a worm gear 405 is fixedly sleeved on one end of the transmission rod 403. Four rotating rods 406 are rotatably connected to the inner wall of the housing 401. A worm wheel 407 is fixedly connected to the surface of each of the four rotating rods 406, and the surface of the worm wheel 407 meshes with the surface of the worm gear 405. A lifting block 404 is fixedly connected to the top of each of the four rotating rods 406. The inner wall of the lifting block 404... A groove is provided, and a lifting rod 408 is slidably connected to the inner wall of the groove of the lifting block 404. One end of the lifting rod 408 extends through the inner wall of the outer shell 401. Positioning blocks 409 are fixedly connected to the surface of the ground penetrating radar body 1. There are four positioning blocks 409. The bottom of the positioning blocks 409 contacts the top of the lifting rod 408. By setting up the lifting mechanism 4, the lifting rod 408 is lifted by rotating the lifting block 404, thereby lifting the ground penetrating radar body 1. By adjusting the height of the ground penetrating radar body 1, the ground penetrating radar body 1 can work normally under different terrain conditions, avoiding collisions between the ground penetrating radar body 1 and ground obstacles, preventing unnecessary damage to the bottom, and improving the safety of the ground penetrating radar body 1 during use.

[0027] Reference Figure 3 A spring 8 is fitted on the surface of the lifting rod 408. One end of the spring 8 is fixedly connected to the surface of the lifting rod 408, and the other end of the spring 8 is fixedly connected to the inner wall of the housing 401. By setting the spring 8, elastic force can be provided to the lifting rod 408, so as to keep the pressure of the lifting rod 408 and the lifting block 404 in contact moderate, thereby improving the stability of the lifting rod 408 moving along the surface of the lifting block 404.

[0028] Reference Figure 4 and Figure 5A damping sleeve 9 is fixedly connected to the inner wall of one end of the lifting rod 408. A ball bearing 10 is rotatably connected to the inner wall of the damping sleeve 9. The surface of the ball bearing 10 contacts the surface of the groove in the inner wall of the lifting block 404. By setting the damping sleeve 9, the ball bearing 10 can be limited to prevent it from rotating due to external factors, thus ensuring the stability of the lifting rod 408. The ball bearing 10 can reduce the resistance when the lifting rod 408 moves within the lifting block 404, making the lifting rod 408 move more smoothly.

[0029] Reference Figure 5 The inner walls of the four positioning blocks 409 are all threaded with bolts 11. The positioning blocks 409 and the lifting rod 408 are fixedly connected by bolts 11. By setting bolts 11, the ground penetrating radar body 1 and the lifting mechanism 4 can be installed and disassembled, which facilitates the maintenance of the ground penetrating radar body 1.

[0030] Reference Figure 1 and Figure 2 The surface of the outer shell 401 is fixedly connected with four first fixing blocks 5. The surface of the movable wheel assembly 2 is fixedly connected with four second fixing blocks 6. The first fixing blocks 5 and the second fixing blocks 6 work together. The ground penetrating radar body 1 and the movable wheel assembly 2 are movably connected through the first fixing blocks 5 and the second fixing blocks 6. By setting the first fixing blocks 5 and the second fixing blocks 6, the ground penetrating radar body 1, the lifting mechanism 4 and the movable wheel assembly 2 can be connected and disassembled, which improves the portability of the ground penetrating radar body 1, the lifting mechanism 4 and the movable wheel assembly 2.

[0031] Reference Figure 6 The inner wall of the first fixing block 5 is provided with a first limiting groove 13, the inner wall of the first limiting groove 13 is provided with a movable groove 16, the inner wall of the second fixing block 6 is provided with a second limiting groove 14, and the inner wall of the second fixing block 6 is provided with a positioning groove 15. By setting the first limiting groove 13, the second limiting groove 14 and the positioning groove 15, space is provided for locking the first fixing block 5 and the second fixing block 6 in the future, ensuring the accuracy of the locking position.

[0032] Reference Figure 6A limiting rod 7 is rotatably connected to the inner wall of the first limiting groove 13, and a limiting rod 7 is movably connected to the inner wall of the second limiting groove 14. A locking block 17 is fixedly connected to one end of the limiting rod 7. The surface of the locking block 17 contacts the inner walls of the second limiting groove 14 and the positioning groove 15. A torsion spring 12 is sleeved on the surface of the limiting rod 7. One end of the torsion spring 12 is fixedly connected to the surface of the limiting rod 7, and the other end of the torsion spring 12 is fixedly connected to the inner wall of the movable groove 16. Through the limiting rod 7 and the locking block 17, the first fixing block 5 and the second fixing block 6 can be locked, ensuring the stability and safety of the connection. The torsion spring 12 can provide elastic potential energy to the limiting rod 7 and the locking block 17, so that the limiting rod 7 and the locking block 17 can quickly return to their original positions after rotation.

[0033] Working principle: The ground-penetrating radar body 1 emits high-frequency electromagnetic waves into the ground through a transmitting antenna. When the electromagnetic waves encounter the interface between different media, they are reflected and refracted. The receiving antenna receives these reflected echoes, processes the signals to form an image, thereby realizing the detection, identification, and location of underground targets. The ground-penetrating radar body 1 can be moved for detection by the moving wheel set 2 and the folding frame 3. By placing the outer shell 401 on the second fixed block 6 of the moving wheel set 2 through the first fixed block 5 on its surface, the user can rotate the limiting rod 7, which drives the locking block 17 to rotate. At the same time, the force of rotation will drive the torsion spring 12 to twist, and the twisted torsion spring 12 will store... By storing deformation potential energy, the user rotates the limiting rod 7 and the locking block 17 to the surface of the second fixed block 6, inserting them into the second limiting groove 14 from the other side of the positioning groove 15. At this point, the user releases the rotating rod 406. Due to the release of the deformation potential energy stored in the torsion spring 12, a reverse force is generated, allowing the limiting rod 7 and the locking block 17 to return to their original positions. The positioning groove 15 locks the locking block 17 within the second limiting groove 14, preventing the first fixed block 5 and the second fixed block 6 from accidentally disengaging. After the lifting mechanism 4 is installed, the user connects the positioning block 409 to the lifting rod 408 using bolts 11, thereby fixing the ground-penetrating radar body 1 to the top. When the surface of the lifting mechanism 4 is uneven, the user can activate two dual-axis motors 402 via an external control switch. The two dual-axis motors 402 are powered by an external power supply. The two outputs of the two dual-axis motors 402 drive the transmission rod 403 to rotate, which in turn drives the worm gear 405 to rotate. The rotation of the worm gear 405 drives the meshing worm wheel 407 to rotate, which in turn drives the rotating rod 406 to rotate. The rotating rod 406 then drives the lifting block 404 to rotate. As the lifting block 404 rotates, its surface becomes inclined, and the lifting rod 408 will engage with the grooves on the surface of the lifting block 404. The groove can limit the lifting rod 408 to prevent it from shifting during the rotation of the lifting block 404. As the lifting block 404 rotates, it will lift the lifting rod 408. The lifted lifting rod 408 will compress the spring 8, which will store elastic potential energy, ensuring that the lifting rod 408 and the lifting block 404 are always in contact. As the lifting rod 408 is lifted, the ground-penetrating radar body 1, which is fixed by the positioning block 409 by the bolt 11 and connected to the lifting rod 408, can be lifted. This allows the user to adjust the height of the ground-penetrating radar body 1 according to the ground conditions, ensuring detection accuracy while protecting the ground-penetrating radar body 1 from damage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
