[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1 provides a sampling device for geological investigation of bridge foundations, such as Figure 1The sampling device includes a mobile mechanism 100, which has mobility. The mobile mechanism 100 may be a platform with wheels. More preferably, the mobile mechanism 100 is a platform with a track structure, which is convenient for traveling in the field. The mobile mechanism 100 provides mobility for the sampling device, and enables the sampling device to move to the sampling position.

[0030] The sampling device includes a mechanical arm 200, which is arranged on the moving mechanism 100. The mechanical arm 200 itself can be bent or straightened and extended.

[0031] like Figure 2 The loosening mechanism 300 and the suction mechanism 400 of the sampling device can be movably arranged on the mechanical arm 200. The mechanical arm 200 can extend the loosening mechanism 300 and the suction mechanism 400 to the soil that needs to be sampled. The loosening mechanism 300 can drill and damage the soil to loosen the soil. The suction mechanism 400 can suck the loosened soil to obtain a soil sample.

[0032] like Figure 3 The sampling device also includes an adjustment mechanism 500, including a rotating pin 501 connected to the loosening mechanism 300 and the suction mechanism 400, and a driving member 502 connected to the rotating pin 501; the driving member 502 can drive the rotating pin 501 to rotate, and the rotating pin 501 can adjust the positions of the loosening mechanism 300 and the suction mechanism 400 when rotating.

[0033] The loosening mechanism 300 and the suction mechanism 400 both have two states. When extended out of the mechanical arm 200, the loosening mechanism 300 and the suction mechanism 400 are in a working state. When retracted into the mechanical arm 200, the loosening mechanism 300 and the suction mechanism 400 are in a standby state. The function of the adjustment mechanism 500 is to adjust the states of the loosening mechanism 300 and the suction mechanism 400. When the loosening mechanism 300 is in a working state, the suction mechanism 400 is in a standby state. After the loosening mechanism 300 has finished working, the loosening mechanism 300 is retracted into the mechanical arm 200 and converted to a standby state, and the suction mechanism 400 is extended out of the mechanical arm 200 to reach a working state. In this way, when the loosening mechanism 300 is working, the suction mechanism 400 will not extend out to cause obstruction. When the suction mechanism 400 is working, the loosening mechanism 300 can be retracted and will not affect the sampling work of the suction mechanism 400. The driving member 502 is a motor.

[0034] Specifically, Figure 2 and Figure 3 The mobile mechanism 100 is also provided with a camera mechanism 600 , which can be a camera that can record the situation at the sampling site. The mechanical arm 200 is also equipped with a bracket 503 , and the driving member 502 is installed on the bracket 503 .

[0035] like Figure 3 and Figure 4 The robot arm 200 is provided with a first slide groove 201 and a second slide groove 202 which are parallel to each other; the loosening mechanism 300 includes a first slide column 301, and the suction mechanism 400 includes a second slide column 401, and the first slide column 301 and the second slide column 401 extend to the inside of the first slide groove 201 and the second slide groove 202 respectively; a limiting groove 5011 is provided on the rotating pin 501, and the first slide column 301 and the second slide column 401 both extend to the inside of the limiting groove 5011.

[0036] When the rotating pin 501 rotates clockwise, the position of the entire limiting groove 5011 also rotates clockwise. Under the limitation of the first slide groove 201, the limiting groove 5011 rotates clockwise to push the first slide column 301 inside the first slide groove 201 to move toward the robot arm 200. At the same time, under the limitation of the second slide groove 202, the limiting groove 5011 rotates clockwise to push the second slide column 401 inside the second slide groove 202 to move away from the robot arm 200, so that the loosening mechanism 300 is retracted into the interior of the robot arm 200 to reach a standby state, and the suction mechanism 400 is extended to the outside of the robot arm 200 to reach a working state.

[0037] Similarly, when the rotating pin 501 rotates counterclockwise, the loosening mechanism 300 can be extended to the outside of the mechanical arm 200 to reach a working state, and the suction mechanism 400 is retracted into the inside of the mechanical arm 200 to reach a standby state.

[0038] like Figure 3 The loosening mechanism 300 includes a first moving platform 302, a drill bit 303 mounted on the first moving platform 302, and a driving motor 304 mounted on the first moving platform 302 and connected to the drill bit 303; the driving motor 304 can reach the drill bit 303 to rotate, and when the drill bit 303 rotates, it can approach the soil to break the soil, and the first sliding column 301 is arranged on the first moving platform 302, and the first moving platform 302 is installed on the mechanical arm 200 through the first sliding column 301. In this embodiment, the number of the first sliding columns 301 is two, and at the same time, the number of the first sliding grooves 201 opened on the mechanical arm 200 is two, and the two first sliding columns 301 are respectively installed on both sides of the first moving platform 302, and the two first sliding columns 301 extend to the inside of the two first sliding grooves 201, respectively. Therefore, when the rotating pin 501 rotates and pushes the first sliding column 301 to move, the first moving platform 302 can be driven to move.

[0039] like Figure 4The suction mechanism 400 includes a second movable platform 402 and a suction tube 403 arranged on the second movable platform 402; a second slide column 401 is arranged on the second movable platform 402, and the second movable platform 402 is installed on the robot arm 200 through the second slide column 401. The same thing is that the number of the second slide columns 401 is two, and the two second slide columns 401 are respectively installed on both sides of the second movable platform 402, and the number of the second slide grooves 202 is two, and the two second slide columns 401 extend to the inside of the two second slide grooves 202 respectively.

[0040] An air pump and a sampling box are installed on the mobile mechanism 100. The air pump is connected to the sampling box, and the sampling box is connected to the suction tube 403. The air pump can suck the air inside the sampling box to reduce the air pressure inside the sampling box. The suction tube 403 sucks external air and soil into the interior of the sampling box.

[0041] Through the scheme in this embodiment, when loosening and breaking the soil, the loosening mechanism 300 maintains a working state and extends to the outside of the mechanical arm 200, and the suction mechanism 400 is stored in the inside of the mechanical arm 200 and does not extend out. At this time, the loosening of the soil by the loosening mechanism 300 will not be affected by the suction mechanism 400. When the loosening is completed, the driving member 502 drives the rotating pin 501 to rotate, and the loosening mechanism 300 is retracted into the inside of the mechanical arm 200 to reach a standby state. At the same time, the suction mechanism 400 extends from the inside of the mechanical arm 200, and can absorb and collect loosened and damaged soil samples. Compared with the sampling device in the prior art, only one mechanical arm 200 is needed to complete the work of loosening the soil and sampling the soil.

[0042] Embodiment 2, as Figure 5 This embodiment is different from the first embodiment in that: in order to avoid the problem of the suction tube 403 being blocked, the suction tube 403 includes a first tube body 404 and a second tube body 405, and the first tube body 404 is installed on the second movable platform 402; the suction mechanism 400 also includes an extension frame 406 slidably connected to the second movable platform 402, and an elastic member 407 provided on the extension frame 406 and the second movable platform 402; the second tube body 405 is installed on the extension frame 406.

[0043] like Figure 5 and Figure 6In the standby state, the first tube body 404 and the second tube body 405 are in a separated state. When the working state is reached, the first tube body 404 and the second tube body 405 reach a docking state. When the rotating pin 501 rotates clockwise, it can push the first movable platform 302 to move in the X direction, and the second movable platform 402 moves in the Y direction. During the movement of the second movable platform 402 in the Y direction, the first tube body 404 can move in the Y direction synchronously. At the same time, the second movable platform 402 can push the extension frame 406 to move in the Y direction through the elastic member 407, so that the second tube body 405 also moves in the Y direction.

[0044] The extension frame 406 is provided with a contact buckle 408. When the first movable platform 302 moves, the extension frame 406 can be driven to move by pushing the contact buckle 408. In the above process, when the first movable platform 302 moves in the X direction and contacts the contact buckle 408 moving in the Y direction, the first movable platform 302 can push the contact buckle 408, so that the moving direction of the contact buckle 408 is changed and it moves in the X direction, so that the contact buckle 408 pulls the extension frame 406, and the extension frame 406 pulls the second tube body 405, so that the first tube body 404 moves in the Y direction, and the second tube body 405 moves in the X direction, so that the first tube body 404 enters the interior of the second tube body 405, and the docking work of the first tube body 404 and the second tube body 405 is completed.

[0045] After the sampling work is completed, the rotating pin rotates counterclockwise, and the first tube body 404 moves in the X direction, and the first moving platform 302 moves in the Y direction. Under the action of the elastic member 407, the second tube body 405 will first move a distance in the Y direction, so that the first tube body 404 and the second tube body 405 are separated, and a gap is generated between them, so that large-volume debris sucked into the first tube body 404 can be discharged.

[0046] The first tube 404 can discharge the debris by sending gas to the first tube 404 through the air pump to push the debris away. Figure 7 The entire sampling device has two air pumps, namely a first air pump 700 and a second air pump 800. The first air pump 700 is connected to a collecting box 900 and is used to extract the air inside the collecting box 900, so as to achieve the purpose of sucking samples. The second air pump 800 is connected to the pipeline between the suction tube 403 and the collecting box 900 and is used to supply air to the suction tube 403, so as to blow out the debris inside the first tube body 404 and avoid the problem of sampling failure caused by debris blocking the suction tube 403.

[0047] The rest of the structure is the same as that of Example 1.

[0048] Example 3, reference Figure 8This embodiment is different from the above embodiments in that: a through groove 4041 is opened on the first tube body 404, and a spring piece 4042 is installed in the through groove 4041 on the first tube body 404; a pushing body 4051 is installed in the second tube body 405; when the second tube body 405 moves toward the first tube body 404, the pushing body 4051 can press the spring piece 4042 to bend and deform toward the axial direction of the first tube body 404.

[0049] refer to Fig. 9 and Fig.10 When the first tube 404 moves in the Y direction and the second tube 405 moves in the X direction, the pushing body 4051 can enter the interior of the second tube 405 and contact the spring sheet 4042, so that the spring sheet 4042 is deformed, so that the spring sheet 4042 can extend to the interior of the first tube 404 to form a blocking structure. During the sampling process, when large-volume debris enters the interior of the first tube 404, the spring sheet 4042 can block the debris. After the sampling is completed or when it is found that the first tube 404 is blocked, the first tube 404 moves in the X direction and the second tube 405 moves in the Y direction by rotating the rotating pin 501 counterclockwise, and the pushing body 4051 and the spring sheet 4042 are separated. During this process, the spring sheet 4042 can push the debris to move to the gap between the first tube 404 and the second tube 405, so that it is easier to clean the debris out of the interior of the first tube 404.

[0050] Specifically, Figure 8 The spring piece 4042 includes a connecting portion 4043 connected to the first tube body 404 , and an arc portion 4044 connected to the connecting portion 4043 and deflected toward the axial direction of the first tube body 404 ; the outer diameter of the first tube body 404 is adapted to the inner diameter of the second tube body 405 .

[0051] The connecting portion 4043 of the spring piece 4042 is fixedly connected to the first tube body 404, and the arc portion 4044 is located at the end of the connecting portion 4043 away from the connection between the connecting portion 4043 and the first tube body 404. When the pushing body 4051 presses the spring piece 4042, the arc portion 4044 of the spring piece 4042 is pressed, so that the arc portion 4044 deflects toward the axial direction of the first tube body 404, so that the spring piece 4042 can form a blocking structure inside the first tube body 404.

[0052] The pushing body 4051 is composed of two parts, one is a positioning structure 4052 connected to the second tube body 405, and the other is a contact structure 4053 fixed on the positioning structure 4052. In this embodiment, the through groove 4041 penetrates to the axial end of the first tube body 404 close to the second tube body 405, and the position of the positioning structure 4052 corresponds to the position of the through groove 4041. When the second tube body 405 moves toward the first tube body 404, the positioning mechanism can enter the interior of the through groove 4041. At the same time, the contact structure 4053 is an arc-shaped structure, which can fit the inner wall of the first tube body 404 when entering the interior of the first tube body 404. It should also be noted that the arc-shaped portion 4044 partially extends into the interior of the first tube body 404 in a natural state, so that the contact structure 4053 can ensure that the pressure side 4045 of the arc-shaped portion 4044 can contact the arc-shaped portion 4044, so that the spring piece 4042 is deformed toward the center of the first tube body 404.

[0053] In order to improve the blocking effect of the spring piece 4042 , more structural extensions may be provided at the end of the spring piece 4042 where the arc portion 4044 extends into the interior of the first tube 404 , which will not be described in detail herein.

[0054] Through the scheme in this embodiment, when the first tube body 404 and the second tube body 405 are combined, the spring piece 4042 on the first tube body 404 can form a blocking structure inside the first tube body 404 to prevent large debris from penetrating into the first tube body 404 and causing blockage. When the second tube body 405 and the first tube body 404 are separated, the spring piece 4042 recovers under the action of its own elasticity. During this process, the debris blocked by the spring piece 4042 is pushed into the gap between the first tube body 404 and the second tube body 405, thereby making it easier to clean the debris out of the first tube body 404.

[0055] The rest of the structure is the same as that of Example 2.
