Description

Technical Field

[0001] This utility model relates to the field of ground penetrating radar technology, specifically to a ground penetrating radar fixing device. Background Technology

[0002] Ground-penetrating radar (GPR) is a geophysical method that uses high-frequency electromagnetic waves to detect underground targets. It transmits and receives high-frequency electromagnetic waves through an antenna, analyzing the reflected signals to obtain information about the structure, distribution, and characteristics of the underground medium. GPR has advantages such as high detection speed, high resolution, and convenient and flexible operation, and is widely used in archaeology, mineral exploration, and engineering surveying. A GPR mounting system is used to fix and support the GPR, ensuring that it can stably and accurately transmit and receive electromagnetic waves during operation.

[0003] However, traditionally, ground-penetrating radar is installed and fixed using screws. During installation, the screws need to be aligned with the mounting holes and tightened one by one, which is very inconvenient. To address these issues, the inventors have proposed a ground-penetrating radar fixing device. Utility Model Content

[0004] To address the problem of inconvenient installation during the use of ground penetrating radar, the purpose of this utility model is to provide a fixing device for ground penetrating radar.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a fixing device for a ground penetrating radar, including a base plate, a top plate at the top of the base plate, a ground penetrating radar body between the base plate and the top plate, the distance between the base plate and the top plate being adjusted by a height adjustment component, a transmission component on one side of the bottom end of the base plate, and protective covers fixedly connected to the bottom end of the base plate and the outer side of the bevel gear and the rotating rod, and a through groove opened on the bottom end of the base plate near the positioning groove, corresponding to the distance between guide cylinder one and guide cylinder two being greater than the length of the ground penetrating radar body;

[0006] The height adjustment assembly includes two symmetrically distributed guide cylinders, one of which is fixedly connected to one side of the top plate. Two threaded rods are rotatably connected to one side of the top of the bottom plate. The guide cylinders are threaded to the outside of the threaded rods. Two symmetrically distributed guide cylinders are fixedly connected to the side of the top plate away from the guide cylinders. The guide cylinders are movably connected through guide rods.

[0007] Preferably, the transmission assembly includes a first bevel gear, the bottom end of the threaded rod extends to the bottom end of the base plate and is fixedly connected to the first bevel gear, a rotating rod is rotatably connected to the bottom end of the base plate near the first bevel gear, both ends of the rotating rod are fixedly connected to a second bevel gear, the second bevel gear meshes with the first bevel gear, a stepper motor is fixedly installed on the bottom end of the base plate near the first bevel gear, the drive end of the stepper motor is fixedly connected to a third bevel gear, the third bevel gear meshes with the corresponding first bevel gear and the rotating rod.

[0008] Preferably, a positioning groove is provided on the opposite side of the top plate and the bottom plate, and the ground-penetrating radar body is placed between the interior of the two positioning grooves.

[0009] Preferably, a limiting block is fixedly connected to the top end of the guide rod, and the limiting block is slidably engaged inside the guide cylinder. The diameter of the limiting block is larger than the diameter of the guide rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] The stepper motor, bevel gear three, and bevel gear one work together to drive the two threaded rods to rotate, which in turn drives the two guide cylinders one to move vertically along the outside of the threaded rods. This adjusts the distance between the positioning groove and the base plate. Then, the ground-penetrating radar body is placed into the positioning groove between guide cylinder one and guide cylinder two. Similarly, the top plate moves downward by rotating the stepper motor in the opposite direction. The position of the ground-penetrating radar body is fixed by the cooperation between the base plate and the top plate. The installation and disassembly are convenient and quick, further improving the flexibility of the equipment during use. Attached Figure Description

[0018] 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 protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a fixing device for a ground penetrating radar, including a base plate 1, a top plate 2 at the top of the base plate 1, a ground penetrating radar body 3 between the base plate 1 and the top plate 2, and a height adjustment component 4 for adjusting the distance between the base plate 1 and the top plate 2. A transmission component 5 is provided on one side of the bottom end of the base plate 1.

[0020] The height adjustment assembly 4 includes two symmetrically distributed guide cylinders 41. The guide cylinders 41 are fixedly connected to one side of the top plate 2. Two threaded rods 42 are rotatably connected to one side of the top of the bottom plate 1. The guide cylinders 41 are threaded to the outside of the threaded rods 42. Two symmetrically distributed guide cylinders 43 are fixedly connected to the side of the top plate 2 away from the guide cylinders 41. The guide cylinders 43 are movably connected through guide rods 44.

[0021] The transmission assembly 5 includes a first bevel gear 51, the bottom end of a threaded rod 42 extends to the bottom end of a base plate 1 and is fixedly connected to the first bevel gear 51, a rotating rod 52 is rotatably connected to the bottom end of the base plate 1 near the first bevel gear 51, and a second bevel gear 53 is fixedly connected to both ends of the rotating rod 52. The second bevel gear 53 meshes with the first bevel gear 51. A stepper motor 54 is fixedly installed on the bottom end of the base plate 1 near the first bevel gear 51, and a third bevel gear 55 is fixedly connected to the drive end of the stepper motor 54. The third bevel gear 55 meshes with the corresponding first bevel gear 51 and rotating rod 52.

[0022] By adopting the above technical solution, the stepper motor 54 drives the bevel gear 3 55 to rotate, and the bevel gear 3 55 meshes with the bevel gear 1 51, thereby driving one of the threaded rods 42 to rotate. The two bevel gears 2 53 mesh with the corresponding two bevel gears 1 51, thereby driving the other threaded rod 42 to rotate, thus realizing the transmission of power.

[0023] Positioning slots 6 are provided on the opposite side of the top plate 2 and the bottom plate 1, and the ground-penetrating radar body 3 is placed between the two positioning slots 6.

[0024] By adopting the above technical solution and setting the positioning slot 6, it is convenient to locate the installation position of the ground penetrating radar body 3.

[0025] A limiting block 45 is fixedly connected to the top of the guide rod 44. The limiting block 45 is slidably engaged inside the guide cylinder 43. The diameter of the limiting block 45 is larger than the diameter of the guide rod 44.

[0026] By adopting the above technical solution and setting the limiting block 45, the vertical movement of the guide rod 44 can be limited, thereby limiting the vertical movement of the top plate 2.

[0027] A protective cover 8 is fixedly connected to the bottom end of the base plate 1 and the outside of the bevel gear 51 and the rotating rod 52.

[0028] By adopting the above technical solution and setting up a protective cover 8, it is convenient to protect the bevel gear 51 and the rotating rod 52.

[0029] A through groove 7 is provided on the bottom end of the base plate 1 near the positioning groove 6.

[0030] By adopting the above technical solution and setting the through slot 7, the electromagnetic wave signal is not blocked, thereby enhancing the signal strength.

[0031] The distance between guide cylinder 1 41 and guide cylinder 2 43 is greater than the length of the ground penetrating radar body 3.

[0032] By adopting the above technical solution, the distance between the corresponding guide cylinder 1 41 and guide cylinder 2 43 is set to be greater than the length of the ground penetrating radar body 3, making it easier to insert the ground penetrating radar body 3 between the guide cylinder 1 41 and guide cylinder 2 43.

[0033] Working principle: When installing and fixing the ground penetrating radar, the stepper motor 54 drives the bevel gear 3 55 to rotate. The bevel gear 3 55 meshes with the bevel gear 1 51, which in turn drives one of the threaded rods 42 to rotate. The two bevel gears 2 53 mesh with the corresponding two bevel gears 1 51, which in turn drives the other threaded rod 42 to rotate. This causes the two guide cylinders 1 41 to move vertically along the outside of the threaded rod 42. The cooperation between the guide cylinder 2 43 and the guide rod 44 makes the vertical movement of the top plate 2 more stable, thereby adjusting the distance between the positioning groove 6 and the bottom plate 1. Then, the ground penetrating radar body 3 is placed into the positioning groove 6 from between the guide cylinder 1 41 and the guide cylinder 2 43. Then, the stepper motor 54 rotates in the opposite direction, which similarly drives the top plate 2 to move downward. The cooperation between the bottom plate 1 and the top plate 2 fixes the position of the ground penetrating radar body 3.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
