Description

Technical Field

[0001] This utility model relates to the field of ground penetrating radar technology, and in particular to a ground penetrating radar that is easy to carry and use. Background Technology

[0002] Ground-penetrating radar (GPR) is a non-destructive detection technology that uses high-frequency electromagnetic waves to detect underground targets. It obtains information about underground structures by emitting electromagnetic waves underground and receiving the reflected signals. The principle of GPR is based on the differences in the propagation speed and reflection characteristics of electromagnetic waves in different media to determine the properties and distribution of underground materials. This technology can provide detailed information about the location, shape, and properties of underground objects, helping researchers understand the structure and material distribution within the Earth. GPR equipment typically includes an antenna, a signal processing system, and imaging software. The antenna is responsible for transmitting and receiving electromagnetic waves, the signal processing system analyzes the reflected signals, and the imaging software generates three-dimensional views and two-dimensional slices to facilitate user interpretation of underground structures.

[0003] A search revealed Chinese Patent Publication No. CN05720652U, which discloses a portable ground-penetrating radar, comprising a base and a ground-penetrating radar. The ground-penetrating radar is embedded in the base, and several rotating brackets are connected to the bottom of the base. Each rotating bracket is connected to a telescopic shaft, and the telescopic shaft is connected to a movable cylinder. A universal wheel disk is set below the movable cylinder, and universal wheels are connected to the bottom of the universal wheel disk. An LED display screen is set on the surface of the ground-penetrating radar. A display screen controller is set on one side of the LED display screen, and a main power switch is set on the other side of the LED display screen. The base is divided into an upper cover plate and a lower cover plate. This portable ground-penetrating radar is simple and convenient to operate, occupies a small area, and is very easy to install. The upper and lower cover plates make it easier to disassemble the ground-penetrating radar and the base, and the universal wheels make it easier to use. The LED display screen can clearly display some basic information of the detection radar, greatly reducing costs. It has low cost and long service life. However, the ground-penetrating radar is used by dragging it with a handle for underground detection. Since the handle is too long and cannot be adjusted, it is inconvenient to load onto a vehicle and transport the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a portable ground-penetrating radar, aiming to improve the usage of existing ground-penetrating radars, which are dragged by a handle for underground detection. However, the handle is too long and cannot be adjusted, making it inconvenient to load onto a vehicle and hindering the transportation of this device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable ground-penetrating radar, comprising a detection device, a first handle rotatably connected to the top rear side of the detection device, a second handle slidably connected inside the first handle, a fixed short column fixedly connected to the top left side of the second handle, a connecting rope fixedly connected to the bottom of the fixed short column, a rotating short column rotatably connected to the top left side of the first handle, the top of the rotating short column being fixedly connected to the bottom of the connecting rope, a fixed plate fixedly connected to the bottom left side of the rotating short column, a locking column installed in the middle of the fixed plate, a slotted circular plate fixedly connected to the upper left side of the first handle, the locking column penetrating the fixed plate and engaging with the middle of the slotted circular plate, and a cleaning mechanism installed on the top front side of the detection device for cleaning the road surface in front of the detection device.

[0006] The above technical solution allows for the following: To adjust the handle length for easy carrying, pull the second handle, which is slidably connected to the first handle, to a suitable length. This will cause the connecting rope to rotate the short column, locking the locking column and the slotted round plate together. When storing, remove the locking column, rotate the part to wrap the connecting rope, and allow the second handle to quickly retract into the first handle. When using, simply hold the adjusted handle.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes two fixed square plates, which are respectively fixedly connected to the left and right ends of the top front side of the detection device. A water spray tank is installed on the top of the fixed square plates. A motor is installed on the left side of the water spray tank. A drive gear is fixedly connected to the output end of the motor. A rotating rod is fixedly connected to the right side of the drive gear. The right side of the rotating rod passes through the left side of the water spray tank. Multiple rotating blades are fixedly connected at equal intervals to the outer side of the rotating rod. A bidirectional threaded rod is threadedly connected to the middle of the fixed square plates. A driven gear is fixedly connected to the left side of the bidirectional threaded rod. The top of the driven gear meshes with the bottom of the drive gear. Sliding rings are threadedly connected to the left and right ends of the bidirectional threaded rod. A cleaning brush is fixedly connected to the front side of the sliding ring. Water inlet pipes are connected to the left and right ends of the top of the water spray tank.

[0009] The above technical solution works as follows: When the road surface in front of the detection device needs to be cleaned, the motor is started, which drives the drive gear, rotating rod and rotating blade to rotate. Water and cleaning fluid enter the water spray tank through the water inlet pipe. The tank sprays water onto the road surface to reduce dust. At the same time, the drive gear drives the driven gear and the bidirectional threaded rod to rotate, which causes the sliding ring to drive the cleaning brush to move in opposite directions. The cleaning brush cooperates to clean and keep the road surface clean.

[0010] As a further description of the above technical solution:

[0011] Limiting plates are fixedly connected to both the left and right ends of the bidirectional threaded rod, and a fixing ring is fixedly connected to the middle of the bidirectional threaded rod.

[0012] The above technical solution prevents the two cleaning brushes from colliding by installing a fixing ring.

[0013] As a further description of the above technical solution:

[0014] A circular cap is installed on the top of the water inlet pipe, and a fixed short circular column is fixedly connected to the top center of the circular cap.

[0015] The above technical solution prevents dirt from entering the spray tank by installing a circular cover.

[0016] As a further description of the above technical solution:

[0017] A second handle is fixedly connected to the middle left side of the rotating short column, and a protective cover is installed on the outside of the second handle.

[0018] The above technical solution facilitates the rotation of the short column by installing a second handle.

[0019] As a further description of the above technical solution:

[0020] A data cable is installed at the top center of the detection device, and a display is provided at the other end of the data cable.

[0021] The above technical solution facilitates the use of the monitor by making it easier for staff to operate.

[0022] As a further description of the above technical solution:

[0023] The first handle is fixedly connected to the top rear side of the second handle, and the top cover is fixedly connected to the top of the second handle.

[0024] The above technical solution facilitates the use of this device by installing the first handle.

[0025] As a further description of the above technical solution:

[0026] A connecting circular plate is fixedly connected to the left side of the fixed short column.

[0027] The above technical solution prevents the connecting rope from getting tangled by installing the connecting circular plate.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, to adjust the length of the handle for easy carrying, pull the second handle, which is slidably connected to the first handle, to a suitable length, drive the connecting rope to rotate the short column, and engage and fix the locking column with the slotted round plate.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a portable ground-penetrating radar, comprising a detection device 1. A first handle 7 is rotatably connected to the top rear side of the detection device 1. A second handle 8 is slidably connected inside the first handle 7. A fixing short post 11 is fixedly connected to the top left side of the second handle 8. The installation of the first handle 7 and the second handle 8 facilitates the storage of the device. A connecting rope 12 is fixedly connected to the bottom of the fixing short post 11. A rotating short post 13 is rotatably connected to the top left side of the first handle 7. The top of the rotating short post 13 is fixedly connected to the bottom of the connecting rope 12. A fixing plate 19 is fixedly connected to the bottom left side of the rotating short post 13. A locking post 20 is installed in the middle of the fixing plate 19. A slotted circular plate 21 is fixedly connected to the upper left side of the handle 7. The engaging column 20 passes through the fixing plate 19 and engages with the middle of the slotted circular plate 21. A cleaning mechanism 2 is installed on the top front side of the detection device 1. The cleaning mechanism 2 is used to clean the road surface in front of the detection device 1. A second handle 14 is fixedly connected to the middle left side of the rotating short column 13. A protective cover 15 is installed on the outside of the second handle 14. The installation of the second handle 14 facilitates the rotation of the rotating short column 13. A first handle 10 is fixedly connected to the top rear side of the second handle 8. A top cover 9 is fixedly connected to the top of the second handle 8. A connecting circular plate 18 is fixedly connected to the left side of the fixing short column 11. The installation of the top cover 9 prevents dirt from entering the device.

[0040] Specifically, when the length of the ground-penetrating radar handle needs to be adjusted for carrying, pull the second handle 8. Since the second handle 8 is slidably connected to the first handle 7, the second handle 8 can be pulled out of the first handle 7 to the required length. Then, drive the connecting rope 12. The bottom of the connecting rope 12 is connected to the rotating short column 13, which is located at the top left side of the first handle 7. As the connecting rope 12 is pulled, the rotating short column 13 will rotate accordingly. After adjusting to the appropriate position, the slot plate 21 is fixed to the upper middle part of the left side of the first handle 7. The locking column 20 is locked to the middle part of the slot plate 21, thereby locking the position of the rotating short column 13 and ensuring that the length of the second handle 8 after being stretched is fixed. When it is necessary to store it, remove the locking column 20 and rotate the second handle 14 so that the connecting rope 12 is wrapped around the outside of the rotating short column 13. In this way, the second handle 8 can be quickly retracted into the inside of the first handle 7 for easy carrying and use. When conducting detection work, simply hold the first handle 7 and the second handle 8 after adjusting the length to start using the ground-penetrating radar.

[0041] Reference Figure 1 , Figure 3 and Figure 5 The cleaning mechanism 2 includes two fixed square plates 209, which are respectively fixedly connected to the left and right ends of the top front side of the detection device 1. A water spray tank 202 is installed on the top of the fixed square plate 209. A motor 201 is installed on the left side of the water spray tank 202. A drive gear 205 is fixedly connected to the output end of the motor 201. The motor 201 provides power to subsequent processes. A rotating rod 210 is fixedly connected to the right side of the drive gear 205. The right side of the rotating rod 210 passes through the left side of the water spray tank 202. Multiple rotating blades 211 are fixedly connected at equal intervals to the outer side of the rotating rod 210. A bidirectional threaded rod 206 is threadedly connected to the middle of the fixed square plate 209. A driven gear 204 is fixedly connected to the left side of 6. The top of the driven gear 204 meshes with the bottom of the driving gear 205. Sliding rings 208 are threadedly connected to the left and right ends of the bidirectional threaded rod 206. The installation of the bidirectional threaded rod 206 allows the two sliding rings 208 to move in the same or opposite directions. A cleaning brush 207 is fixedly connected to the front side of the sliding ring 208. Water inlet pipes 203 are connected to the top left and right ends of the water spray tank 202. Limiting plates 5 are fixedly connected to the left and right ends of the bidirectional threaded rod 206. A fixing ring 6 is fixedly connected to the middle of the bidirectional threaded rod 206. A circular cover 3 is installed on the top of the water inlet pipe 203. A fixed short cylindrical column 4 is fixedly connected to the top center of the circular cover 3.

[0042] Specifically, when cleaning is required on the road surface in front of the detection device 1, the motor 201 is started, driving the drive gear 205 to rotate. The rotating rod 210, fixed to the right side of the drive gear 205, rotates synchronously. Multiple rotating blades 211, equidistantly mounted on the outer side of the rotating rod 210, rotate within the water spray tank 202. Through the installation of two water inlet pipes 203, both water and cleaning fluid can enter the water spray tank 202. Water is then sprayed onto the road surface through the water spray tank 202, wetting the road and reducing dust, facilitating subsequent cleaning. Simultaneously, the drive gear... The rotation of 205 drives the bidirectional threaded rod 206, which is meshed with its bottom, to rotate. The threads on both sides of the bidirectional threaded rod 206 are in opposite directions. The sliding rings 208, which are threaded to the left and right ends of the outer side, move towards or away from each other during the rotation of the bidirectional threaded rod 206. The cleaning brush 207 fixed on the front side of the sliding ring 208 moves accordingly. The two cleaning brushes 207 cooperate with each other to clean the road surface in front of the detection device 1, clearing debris to both sides, thereby keeping the road surface in front of the detection device 1 clean, ensuring that the detection work is not interfered with by road debris, and improving the detection accuracy.

[0043] Reference Figure 1 , Figure 2 and Figure 3 A data cable 16 is installed at the top center of the detection device 1, and a display 17 is installed at the other end of the data cable 16.

[0044] Specifically, the installation of the display 17 facilitates observation by this device.

[0045] Working principle: When the length of the ground-penetrating radar handle needs to be adjusted for carrying, pull the second handle 8. Since the second handle 8 is slidably connected to the first handle 7, the second handle 8 can be pulled out of the first handle 7 to a suitable length. Then, drive the connecting rope 12. The bottom of the connecting rope 12 is connected to the rotating short column 13. The rotating short column 13 is rotatably connected to the top left side of the first handle 7. As the connecting rope 12 is pulled, the rotating short column 13 will rotate and be adjusted to a suitable position. The slot plate 21 is fixed to the upper middle part of the left side of the first handle 7. The locking column 20 is locked to the middle part of the slot plate 21, thereby fixing the position of the rotating short column 13, which also fixes the position of the second handle 8 after it is stretched. When it needs to be stored, remove the locking column 20 and rotate the second handle 14 so that the connecting rope 12 is wrapped around the outside of the rotating short column 13, so that the second handle 8 can be quickly put into the inside of the first handle 7 for easy carrying and use. When using the ground-penetrating radar for detection work, simply hold the first handle 7 and the second handle 8 after adjusting the length.

[0046] When it is necessary to clean the road surface in front of the detection device 1, the motor 201 is started. The motor 201 drives the drive gear 205 to rotate. The rotating rod 210 fixed on the right side of the drive gear 205 rotates synchronously with it. Multiple rotating blades 211 fixed at equal intervals on the outer side of the rotating rod 210 rotate inside the water spray tank 202. Through the installation of two water inlet pipes 203, water and cleaning fluid can enter the water spray tank 202. Water is sprayed onto the road surface through the water spray tank 202 to moisten the road surface and reduce dust, facilitating subsequent cleaning. At the same time, when the drive gear 205 rotates... The driven gear 204, which meshes with the bottom of the bidirectional threaded rod 206, also rotates. The threads on the left and right sides of the bidirectional threaded rod 206 are opposite in direction. The sliding rings 208 connected to the threads on the left and right sides of the outer side will move towards or away from each other during the rotation of the bidirectional threaded rod 206. The cleaning brush 207 fixed on the front side of the sliding ring 208 moves accordingly. The two cleaning brushes 207 cooperate with each other to clean the road surface in front of the detection device 1, clearing debris to both sides, thereby keeping the road surface in front of the detection device 1 relatively clean, ensuring that the detection work is not interfered with by road debris, and improving the detection accuracy.
