Description

Technical Field

[0001] This invention relates to the field of geological exploration technology, specifically a sampling device for geological exploration. Background Technology

[0002] Geological exploration is the investigation and research of geological conditions, including rocks, stratigraphic structure, mineral resources, groundwater, and landforms, within a specific area, using methods such as surveying, geophysical exploration, geochemical prospecting, drilling, pitting, sampling and testing, and geological remote sensing. Geological exploration is a crucial foundation for construction projects. However, rocky areas differ from general areas, with complex rock structures, making geological exploration operations challenging. Even slight errors can lead to significant mistakes, creating potential safety hazards for construction projects. There are many methods for geological exploration, such as drilling, well exploration, and probing. Although different methods have different characteristics, they all rely on professional and precise surveying equipment. Among them, geological exploration drilling sampling work can easily damage the samples, which will affect the sampling results. This is especially true when sampling in areas with loose soil, which will bring certain difficulties to the sampling work. At the same time, when the sampling area is in a complex terrain environment, the transportation of sampling equipment becomes a major problem. Existing sampling equipment is usually not easy to transport and requires a lot of manpower and resources to reach the sampling point. How to solve the problem of difficult equipment transportation in complex terrain and the lack of lightweight equipment is of great significance to improving the sampling efficiency and reducing the manpower consumption in geological exploration. Summary of the Invention

[0003] The purpose of this invention is to provide a sampling device for geological exploration. Based on the integrated sampling-lifting concept and combined with automation technology, the optimal route to the sampling area is calculated by combining the actual terrain and positioning system. The navigation route can be optimized by using GPS navigation technology combined with the actual terrain atlas, realizing the sampling needs of unmanned transportation. To a certain extent, it improves the sampling efficiency in geological exploration and reduces the consumption of manual labor, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for geological exploration, comprising a drilling sampling unit for extracting soil samples for geological exploration, a lifting and raising unit for raising the drilling sampling unit from underground to the surface, a positioning and guiding unit for transporting the drilling sampling unit to a sampling area, and a control unit for controlling the operation of the sampling device. The drilling sampling unit includes a drill bit for drilling, the drill bit being threadedly connected to a drill rod at its top. A connector is connected to the top of the drill rod, and a vibration device for controlling the drilling and sampling of the drill bit is connected above the connector. The vibration device is provided with a hose interface for connecting a hose, the hose being wound around a hose shaft. One end of the hose shaft is detachably connected to the vibration device, and the other end is fixedly connected to a connecting hub. Handles are provided on both sides of the vibration device. A damping pad is provided between the handle and the vibration device. The lifting unit includes a connector connected to the upper surface of the sampling device. A support rod is provided above the connector to support the operation of several blades and provide sufficient operating space. The positioning and guiding unit includes couplings located on both sides of the sampling device. One end of the coupling is fixedly connected to the connecting hub, and the other end is connected to a robotic arm for controlling direction. The bottom of the robotic arm is connected to a base, and a caster wheel for ground guidance is connected below the base. The control unit includes a camera for acquiring real-time images during the sampling process, a positioning device with positioning function, and a driver for control. The connecting hub is connected below the control unit. The control unit controls the sampling operation of the sampling device by controlling the rotation and operation of the connecting hub.

[0005] As a further aspect of the present invention: the drilling sampling unit employs an acoustic vibration sampling method to sample the sampling area. Due to the complex terrain of the sampling area, using large sampling machinery would present problems such as difficulty in transporting the machinery, time-consuming and labor-intensive transport, and potential damage. Therefore, using an acoustic vibration system can improve the portability of the device while ensuring normal sampling operations. The vibration device plays a controlling role in the sampling process within the drilling sampling unit. This vibration device includes a lifting ring connected to the flexible hose shaft. After sampling, the flexible and elastic nature of the hose can cause shaking during the lifting process by the lifting unit, potentially damaging the sample. Therefore, the lifting ring is provided and connected to the flexible hose shaft. The flexible hose shaft is connected to the connecting hub, and the upward lifting of the connecting hub by the lifting unit controls the stable operation of the sampling lifting process.

[0006] As a further embodiment of the present invention: the vibration device includes a power system that provides power for the sampling operation, and a sound vibration generator is connected below the power system to provide the sound vibration frequency required for sampling. A speed regulating device is connected below the sound vibration generator. The frequency provided by the sound vibration generator may not reach the sampling rate standard, so the speed regulating device is provided to control the sampling rate and prevent unstable sampling rate from causing damage to the sample during the sampling operation, so that the sample cannot be completely removed.

[0007] As a further aspect of the present invention: the pad and the handle are an auxiliary mechanism. Mechanical vibration will occur during the sampling process, so the handle is provided to help the sampling staff manually assist the sampling device to ensure the stability of the sampling. At the same time, in order to prevent excessive mechanical vibration from being detrimental to the sampling staff, the pad is provided to buffer the force exerted by the sampling device on the sampling staff.

[0008] As a further embodiment of the present invention: the connector is fixedly connected to the surface of the sampling device. Above the connector is a support rod for supporting the operation of several blades. The bottom end of the support rod is provided with a drive device for driving the operation of several blades. The top end of the support rod is provided with a four-sided extending frame for connecting the blades. The lifting and raising unit can drive the operation of several blades to drive the main body of the sampling device below to fly upward. When encountering obstacles on the way to the sampling area, the lifting and raising unit can avoid the obstacles by lifting them, thereby reducing the manual work of clearing obstacles. Furthermore, when the sampling drill needs to be lifted from underground after sampling, the rotation speed of the blades can be controlled to lift the sampling device, eliminating the need to carry the lifting mechanism separately. The sampling-lifting integration reduces the intensity of manual transportation.

[0009] As a further aspect of the present invention: the positioning and guiding unit has an automatic driving function system that also includes a manual remote control system. The automatic driving function is mainly achieved by the control unit collecting real-time terrain images and the positioning and navigation system controlling the operation of the connecting hub through the driver to transmit driving commands to the positioning and guiding unit. The positioning and guiding unit controls the running direction of the robotic arm through the driving commands. The robotic arm is a telescopic tubular arm. When the sampling terrain is complex and the carrying space is insufficient, the length of the robotic arm can be adjusted to save space. The bottom end of the robotic arm is connected to a base for connecting the universal wheels. The universal wheels are flexibly connected to the base, and the surface material of the universal wheels is a wear-resistant material. Because the sampling area is mostly uneven ground with many sharp stones, the surface material of the universal wheels needs to be a wear-resistant material to prevent damage to the universal wheels and thus obstruction of the sampling device's movement on the ground.

[0010] As a further aspect of the present invention: the control unit is the core control center of the sampling device. By combining the actual terrain conditions and the positioning system, the optimal route to the sampling area is calculated. The camera is located on the surface of the sampling device and can slide around the surface of the sampling device to achieve the purpose of all-round acquisition of terrain images. The positioning device is a coordinate positioning system. By locating the coordinates of the sampling area, GPS navigation technology can be used to select the navigation route to the sampling point. At the same time, combined with the actual terrain atlas, the navigation route can be optimized in a timely manner. The continuously optimized navigation route data signal is transmitted to the driver, and the driver issues instructions to transmit the instructions to each module to realize the automation of the sampling device. In addition, to ensure the safe operation of the sampling device, a remote control device can be configured. When the sampling device cannot transport and collect samples on its own, the sampling staff can remotely control the operation of the sampling device.

[0011] As a further aspect of the present invention, a sampling device for geological exploration includes the following steps: Step 1: Preparation. Before operating the sampling device, check whether the control unit is in normal working condition and whether the transmission connection between each unit is unobstructed. At the same time, check the wear condition of each connection of the sampling device to prevent wear at the connection from causing the device to malfunction. Step Two: After the safety inspection is completed, turn on the control unit. By combining the actual terrain and the positioning system, the optimal route to the sampling area is calculated. The camera located on the surface of the sampling device collects the actual terrain images. The camera can also slide around the surface of the sampling device to achieve the purpose of collecting terrain images from all directions. In addition, the positioning device is a coordinate positioning system. By locating the coordinates of the sampling area, GPS navigation technology can be used to select the navigation route to the sampling point. At the same time, combined with the actual terrain atlas, the navigation route can be optimized in time. The continuously optimized navigation route data signal is transmitted to the driver, and the driver issues instructions to transmit the instructions to each module to realize the automation of the sampling device. In addition, to ensure the safe operation of the sampling device, a remote control device can be configured. When the sampling device cannot transport and collect samples on its own, the sampling staff can remotely control the operation of the sampling device. Step 3: Following the optimized route guidance, the positioning and guidance unit navigates the sampling device to the sampling point. The positioning and guidance unit controls the running direction of the robotic arm through driving commands. The robotic arm is a telescopic tubular arm. When the sampling terrain is complex and the carrying space is insufficient, the length of the robotic arm can be adjusted to save space. The bottom end of the robotic arm is connected to a base for connecting the casters. The casters are flexibly connected to the base, and the surface material of the casters is a wear-resistant material. Because the sampling area is mostly uneven ground with many sharp stones, the surface material of the casters needs to be wear-resistant to prevent damage to the casters and thus prevent the sampling device from being obstructed on the ground. Step 4: Upon reaching the sampling point, an acoustic vibration sampling method is used to sample the area. Using an acoustic vibration system improves the portability of the device while ensuring normal sampling operations. The vibration device plays a controlling role in the drilling sampling unit. This device includes a lifting ring connected to the flexible hose shaft. After sampling, due to the flexible and elastic nature of the hose, the lifting process by the lifting unit can cause shaking, potentially damaging the sample. Therefore, the lifting ring is connected to the flexible hose shaft. The flexible hose shaft is connected to the connecting hub, and the lifting unit drives the upward lifting of the connecting hub, thus controlling the stability of the sampling lifting process. The vibration device also includes a power source to provide power for the sampling operation. The system includes a sound vibration generator connected below the power system to provide the sound vibration frequency required for sampling. A speed regulating device is connected below the sound vibration generator. Since the frequency provided by the sound vibration generator may not meet the sampling rate standard, the speed regulating device is provided to control the sampling rate and prevent unstable sampling rate from damaging the sample and preventing the sample from being completely extracted. The drilling sampling unit also includes a pad and a handle. The pad and the handle are auxiliary mechanisms. Mechanical vibration will occur during the sampling process, so the handle is provided for the sampling staff to manually assist the sampling device in sampling stability. At the same time, in order to prevent excessive mechanical vibration from being detrimental to the sampling staff, the pad is provided to buffer the force of the sampling device on the sampling staff. Step 5: Lift the drilled sample to the ground. The lifting unit includes a connector fixedly connected to the surface of the sampling device. Above the connector is a support rod for supporting the operation of several rotary blades. The bottom end of the support rod is equipped with a drive device for driving the rotary blades. The top end of the support rod is equipped with a four-sided extending frame for connecting the rotary blades. The lifting unit drives the operation of the rotary blades, which in turn drives the main body of the sampling device to fly upwards. When encountering obstacles on the way to the sampling area, the lifting unit can avoid obstacles by lifting them, thus reducing the manual work of clearing obstacles. Furthermore, when the drilling tool needs to be lifted from underground after sampling, the rotation speed of the rotary blades can be controlled to lift the sampling device, eliminating the need to carry a separate lifting mechanism. Integrating sampling and lifting reduces the intensity of manual transportation.

[0012] Compared with the prior art, the beneficial effects of the present invention are: based on the integrated sampling-lifting concept and combined with automation technology, the optimal route to the sampling area is calculated by combining the actual terrain conditions and the positioning system. The navigation route can be optimized by using GPS navigation technology combined with the actual terrain atlas, which can realize the sampling needs of unmanned transportation, improve the sampling efficiency in geological exploration to a certain extent and reduce the consumption of human labor.

[0016] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0017] Example: Please see Figures 1-4In this embodiment of the invention, a sampling device for geological exploration includes a drilling sampling unit (1) for extracting soil samples for geological exploration, a lifting and raising unit (2) for raising the drilling sampling unit (1) from underground to the surface, a positioning and guiding unit (3) for transporting the drilling sampling unit (1) to the sampling area, and a control unit (4) for controlling the operation of the sampling device. The drilling sampling unit (1) includes a drill bit (11) for drilling, and the drill bit (11) is threadedly connected to a drill rod (12) at the top. A connector (13) is connected above the drill rod (12). A vibration device (14) for controlling the drilling and sampling of the drill bit (11) is connected above the connector (13). The vibration device (14) is provided with a hose interface (145) for connecting a hose (17). The hose (17) is wound around a hose shaft (18). One end of the hose shaft (18) is detachably connected to the vibration device (14), and the other end is fixedly connected to the connecting hub (19). Handles (16) are provided on both sides of the vibration device (14). 6) A damping pad (15) is provided between the vibration device (14). The lifting unit (2) includes a connector (21) connected to the upper surface of the sampling device. A support rod (22) is provided above the connector (21) to support the operation of several blades (23) and provide sufficient operating space. The positioning and guiding unit (3) includes a coupling (31) located on both sides of the sampling device. One end of the coupling (31) is fixedly connected to a connecting hub (19), and the other end is connected to a robotic arm (32) for controlling the direction. The bottom of the robotic arm (32) is connected to a base (33). Under the base (33) is a universal wheel (34) for ground guidance. The control unit (4) includes a camera (41) for collecting real-time images during the sampling process, a positioning device (42) with positioning function, and a driver (43) for control. The control unit (4) is connected to the connecting hub (19) below. The control unit (4) controls the sampling operation of the sampling device by controlling the rotation and operation of the connecting hub (19).

[0018] like Figures 1-4 As shown, the present invention also provides a method for using a sampling device for geological exploration, the specific steps of which are as follows: Step 1: Preparation. Before the sampling device is running, check whether the control unit (4) is in normal working condition and whether the transmission connection between each unit is unobstructed. At the same time, check the wear condition of each connection of the sampling device to prevent wear at the connection from causing the device to malfunction. Step 2: After the safety inspection is completed, turn on the switch of the control unit (4). By combining the actual terrain and the positioning system, the best route to the sampling area is calculated. The camera (41) located on the surface of the sampling device collects the actual terrain image. At the same time, the camera (41) can slide around the surface of the sampling device to achieve the purpose of collecting the terrain image from all directions. In addition, the positioning device (42) is a coordinate positioning system. By locating the coordinates of the sampling area, the GPS navigation technology can be used to select the navigation route to the sampling point. At the same time, the navigation route can be optimized in time by combining the actual terrain map. The continuously optimized navigation route data signal is transmitted to the driver (43). The driver (43) issues instructions to transmit the instructions to each module to realize the automation of the sampling device. At the same time, in order to ensure the safe operation of the sampling device, a remote control device can be configured. When the sampling device cannot transport the sample by itself, the sampling staff can remotely control the operation of the sampling device. Step 3: The sampling device is guided to the sampling point by the positioning and guidance unit (3) according to the optimized route. The positioning and guidance unit (3) controls the running direction of the robotic arm (32) through driving commands. The robotic arm (32) is a telescopic tube arm. Due to the complex sampling terrain, the length of the robotic arm (32) can be adjusted to save space when the carrying space is insufficient. The bottom end of the robotic arm (32) is connected to the base (33) for connecting the caster wheel (34). The caster wheel (34) is flexibly connected to the base (33), and the surface material of the caster wheel (34) is a wear-resistant material. Because the sampling area is mostly uneven ground and there are many sharp stones on the ground, the surface material of the caster wheel (34) needs to be a wear-resistant material to prevent the operation of the caster wheel (34) from being damaged and causing the sampling device to be obstructed on the ground. Step 4: After arriving at the sampling point, the sampling work is carried out by using the sound frequency vibration sampling method. Due to the complex terrain of the sampling area, if large sampling machinery is used, there will be problems with the difficulty of transporting the machinery and the time and effort required for the transport work, as well as the problem of damage to the machinery. Therefore, the sound vibration system can improve the portability of the device while ensuring the normal operation of the sampling work. The vibration device (14) plays the role of sampling control in the drilling sampling unit (1). The vibration device (14) includes a lifting ring (141) connected to the hose shaft (18). After the sampling is completed, due to the soft and elastic nature of the hose (17), the lifting process by the lifting unit (2) will cause the lifting work to shake and damage the sample. Therefore, a lifting ring (141) is provided and connected to the hose shaft (18). The hose shaft (18) is connected to the connecting hub (19). The lifting unit (2) drives the connecting hub (19) to lift upward, thereby controlling the stable operation of the sampling lifting work. At the same time, the vibration device (141) 4) It also includes a power system (142) that provides power for sampling. The power system (142) is connected to a sound vibration generator (144) to provide the sound vibration frequency required for sampling. The sound vibration generator (144) is connected to a speed regulating device (143). The frequency provided by the sound vibration generator (144) may not meet the sampling rate standard, so a speed regulating device (143) is set to control the sampling rate to prevent the sampling rate from being unstable and causing damage to the sample, so that the sample cannot be completely taken out. The drilling sampling unit (1) also includes a pad (15) and a handle (16). The pad (15) and the handle (16) are auxiliary mechanisms. Since mechanical vibration will occur during the sampling process, a handle (16) is set for the sampling staff to manually assist the sampling device in sampling stability. At the same time, in order to prevent excessive mechanical vibration from being detrimental to the sampling staff, a pad (15) is set to buffer the force of the sampling device on the sampling staff. Step 5: Pull the drilled sample to the ground. The lifting unit (2) includes a connector (21), which is fixedly connected to the surface of the sampling device. Above the connector (21) is a support rod (22) for supporting the operation of several blades (23). The bottom end of the support rod (22) is equipped with a drive device for driving the operation of several blades (23). The top end of the support rod (22) is equipped with a four-sided extended frame for connecting the blades (23). The lifting unit (2) can drive the operation of several blades (23) to drive the main body of the sampling device below to fly upward. When encountering obstacles on the way to the sampling area, the lifting unit (2) can avoid obstacles by lifting them, thereby reducing the work of clearing obstacles manually. When the sampling drill needs to be lifted from the ground after sampling, the rotation speed of the blades (23) can be controlled to lift the sampling device, eliminating the need to carry the lifting mechanism separately. The sampling-lifting integration reduces the intensity of manual transportation.

[0019] The working principle of this invention is as follows: Based on the integrated sampling-lifting concept and combined with automation technology, the optimal route to the sampling area is calculated by combining the actual terrain conditions and the positioning system. The navigation route can be optimized by using GPS navigation technology combined with the actual terrain atlas, which can realize unmanned transportation sampling, thereby improving the sampling efficiency in geological exploration to a certain extent and reducing the consumption of human labor.

[0020] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

By adjusting the length of the robotic arm (32), space is saved. The bottom end of the robotic arm (32) is connected to a base (33) for connecting the universal wheel (34). The universal wheel (34) is flexibly connected to the base (33), and the surface material of the universal wheel (34) is a wear-resistant material.

The vibration device (14) plays a sampling control role in the drilling sampling unit (1). The vibration device (14) includes a lifting ring (141) connected to the hose shaft (18). After sampling, due to the flexible and elastic nature of the hose (17), the lifting process by the lifting unit (2) will cause shaking and damage to the sample. Therefore, the lifting ring (141) is provided to connect to the hose shaft (18).

The sound vibration generator (144) is connected to a speed regulating device (143). Since the frequency provided by the sound vibration generator (144) does not meet the sampling rate standard, the speed regulating device (143) is provided to control the sampling rate and prevent the sampling work from damaging the sample due to the unstable sampling rate, so that the sample cannot be completely taken out. The drilling sampling unit (1) also includes a pad (15) and a handle (16). The pad (15) and the handle (16) are auxiliary mechanisms. The pad (15) is provided to buffer the force of the sampling device on the sampling staff. Step 5: Pull the drilled sample to the ground. The lifting unit (2) includes a connector (21), which is fixedly connected to the surface of the sampling device. Above the connector (21) is a support rod (22) for supporting the operation of several blades (23). The bottom end of the support rod (22) is provided with a drive device for driving the operation of several blades (23). The top end of the support rod (22) is provided with a four-sided extending frame for connecting the blades (23). The lifting unit (2) drives the operation of several blades (23) to drive the main body of the sampling device below to fly upward. When encountering obstacles on the way to the sampling area, the lifting unit (2) avoids the obstacles by lifting the obstacles, thereby reducing the work of clearing obstacles manually. When the sampling drill needs to be lifted from the ground after sampling, the rotation speed of the blades (23) is controlled to lift the sampling device.
