Description

Technical Field

[0001] This utility model belongs to the field of land underground structure detection technology, and in particular relates to a ground penetrating radar component and land underground structure detection equipment. Background Technology

[0002] Land subsurface structure detection mainly relies on geophysical exploration technology, combined with geological drilling, remote sensing and measurement technologies, to efficiently and non-destructively obtain subsurface structure information, providing a scientific basis for land planning, resource development and disaster prevention.

[0003] Ground penetrating radar (GPR) is one of the commonly used devices for detecting underground structures in land. Its core principle is to transmit pulsed electromagnetic waves into the ground through a transmitting antenna. When the electromagnetic waves encounter an interface with a difference in electrical conductivity and dielectric constant, they are reflected. The receiving antenna captures the reflected waves and records information such as their travel time, amplitude, and phase. Then, through data processing, two-dimensional or three-dimensional images of the underground structure are generated.

[0004] Ground penetrating radar can be carried on various carriers, including drones, motor vehicles, and trolleys. When mounted on a trolley, the trolley is moved manually, and data on a tablet computer needs to be observed during the movement. In the current technology, trolleys are usually equipped with two types of working wheels: omnidirectional wheels for more flexible movement on flat ground and ordinary wheels for greater stability on rough ground. However, the two types of working wheels cannot be quickly replaced, and disassembly and replacement are time-consuming. Furthermore, during the detection process, the operator's attention is mainly focused on the tablet computer, and they cannot observe the ground conditions in real time. The front or bottom of the equipment is prone to collisions with easily overlooked obstacles such as rocks and ground protrusions, which can damage the equipment.

[0005] To address this, we propose a ground-penetrating radar component and a device for detecting underground structures in the land. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to quickly replace the two types of working wheels, the time-consuming disassembly and replacement, the operator's attention being mainly on the tablet during the detection process, the inability to observe the ground conditions in real time, and the easy collision of the front or bottom of the equipment with easily overlooked obstacles such as stones and ground protrusions, which can damage the equipment. Therefore, this invention proposes a ground-penetrating radar component and a land underground structure detection device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A ground-penetrating radar assembly, comprising:

[0009] The ground-penetrating radar body has mounting plates fixed on both sides and a battery box fixed on the top of the ground-penetrating radar body.

[0010] The mounting base has an inclined tablet computer fixedly mounted on one side, and a connecting groove is provided at the bottom of the mounting base.

[0011] A land underground structure detection device, including a ground-penetrating radar component;

[0012] It also includes a base plate, the surface of which is provided with a mounting groove, and the ground-penetrating radar body is placed in the mounting groove and fixed to the base plate by the mounting plate;

[0013] It also includes two sleeves fixed to the surface of the base plate, with a U-shaped handrail inserted between the two sleeves. The mounting base is sleeved on the top outer wall of the handrail through a connecting groove and fixed to the handrail with bolts.

[0014] It also includes a rotating shaft that passes through the front end of the base plate. Both ends of the rotating shaft are fixed with front ordinary wheels. A rectangular groove is opened on the surface of the base plate, through which the rotating shaft passes.

[0015] It also includes two rotating seats that are rotatably connected to the rear end of the base plate, with a rear ordinary wheel and a universal wheel installed on each side of the rotating seats respectively;

[0016] The braking mechanism, located on the front surface of the base plate, is used to brake the rotating shaft.

[0017] The detection mechanism, located on one side of the braking mechanism, is used to detect the ground height in front of the equipment as it moves.

[0018] The adjustment mechanism, located at the rear end of the base plate, is used to switch between the rear ordinary wheels and the swivel wheels.

[0019] In one possible design, the braking mechanism includes a connecting shell fixed to the surface of the base plate, an electric push rod fixed to the top inner wall of the connecting shell, a pressure block fixed to one end of the output shaft of the electric push rod, and an arc-shaped groove at the bottom of the pressure block.

[0020] In one possible design, guide strips are fixedly provided on both inner walls of the connecting shell, and guide grooves are provided on both sides of the pressure block, with the guide strips and guide grooves slidingly engaged.

[0021] In one possible design, the detection mechanism includes a connecting plate fixed to the outer wall of one side of the connecting shell, with an infrared sensor and an ultrasonic sensor fixed to the bottom of the connecting plate.

[0022] In one possible design, the adjustment mechanism includes positioning blocks fixed on the surface and one side of the rotating seat, two slides slidably connected to the rear end of the base plate, and a bidirectional lead screw rotatably connected to the rear end of the base plate. The slides have positioning grooves on the side facing the rotating seat, and the positioning grooves cooperate with the positioning blocks. Threaded sleeves are fixed on the opposite sides of the two slides, and the two ends of the bidirectional lead screw are threadedly connected to the two threaded sleeves respectively.

[0023] In one possible design, a rubber adjusting sleeve is fixedly fitted on the middle of the outer wall of the bidirectional lead screw, and a reinforcing rod is fixed between the two sleeves.

[0024] In one possible design, the outer wall of the handrail is provided with two sets of limiting grooves, and the outer walls of the two sleeves are threaded through with limiting bolts, one end of which is located in one of the limiting grooves.

[0025] In this application, when in use, the operator turns on the ground penetrating radar and tablet computer, and uses the handrail to push the equipment forward. The ground penetrating radar transmits pulsed electromagnetic waves into the ground through the transmitting antenna. When the electromagnetic waves encounter the interface of electrical difference in dielectric constant and conductivity, they are reflected. The receiving antenna captures the reflected waves and records information such as their travel time, amplitude and phase. Then, the tablet computer processes the data to generate two-dimensional or three-dimensional images of the underground structure and displays them.

[0026] During the journey, infrared sensors and ultrasonic sensors work together to monitor the road ahead of the equipment in real time. When an obstacle is detected and its height is higher than the bottom of the equipment, the electric push rod is activated to drive the pressure block down and press the rotating shaft, causing the equipment to slow down and stop. The operator uses a tablet computer to control the electric push rod to reset the pressure block and adjust the forward path of the equipment.

[0027] When switching between ordinary wheels and universal wheels, rotate the adjusting sleeve to drive the bidirectional lead screw to rotate, which in turn drives the slide to move and separate from the rotating seat, so that the positioning block and the positioning groove are separated. Then rotate the rotating seat ninety degrees, and then rotate the adjusting sleeve in the opposite direction to make the positioning block and the positioning groove engage. After the slide blocks abut against the rotating seat again, it can be used. The operation is simple and convenient.

[0028] When the height of the handrail needs to be adjusted, rotate the limit bolt to disengage it from the limit groove, then move the handrail to the appropriate height, and rotate the limit bolt again to re-enter the corresponding limit groove.

[0029] Beneficial effects: In this utility model, the ground penetrating radar component and land underground structure detection equipment can quickly switch between the rear ordinary wheels and the universal wheels through the setting of structures such as rear ordinary wheels, universal wheels and rotating seats, without the need for disassembly and replacement, saving the operator's time;

[0030] In this utility model, the ground-penetrating radar component and the land underground structure detection device, through the setting of such structures, can detect the ground conditions in front of the device and can brake the device in an emergency when encountering obstacles to avoid collision damage.
