[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] like Figure 1-7 As shown, a soil and groundwater sampling and detection device includes a main body 1, a support column 2 is fixedly connected to the outside and inside of the main body 1, a disc 3 is fixedly connected to the outside of the support column 2, and a storage and replacement mechanism is provided on the outside of the disc 3. The storage and replacement mechanism includes a first rotating shaft 7 disposed on the outside of the disc 3, a fixed block 6 is fixedly connected to the outside of the first rotating shaft 7, a water storage tank 10 is fixedly mounted on the outside of the fixed block 6, and a soil storage tank 14 is fixedly mounted on the outside of the fixed block 6;

[0036] The outside of the main body 1 is rotatably connected to the fourth rotating shaft 19, and a soil sampling mechanism is provided on the outside of the fourth rotating shaft 19. The soil sampling mechanism includes a second bevel gear set 21 arranged on the outside of the fourth rotating shaft 19, and the outside of the second bevel gear set 21 is fixedly connected to the fifth rotating shaft 22, and the outside of the fifth rotating shaft 22 is fixedly connected to the excavation plate 23. An opening 24 is opened on the outside of the main body 1.

[0037] In this embodiment, the support column 2 is provided in multiple configurations to facilitate maintaining the stability of the disc 3. When sampling of soil and groundwater at different depths is required, the first rotating shaft 7 is rotated. The rotation of the first rotating shaft 7 simultaneously drives the externally fixed fixed block 6 to rotate, and the fixed block 6 drives the externally fixedly mounted water storage tank 10 and soil storage tank 14 to rotate simultaneously. The water storage tank 10 and soil storage tank 14 are provided in multiple configurations, so that unused water storage tanks 10 and soil storage tanks 14 can be moved to the sampling location, that is, sampling can be performed again, which facilitates a comprehensive understanding of the pollution status of the soil and groundwater and obtains more comprehensive pollution data.

[0038] When it is necessary to sample the soil, the fourth rotating shaft 19 is rotated, and the fourth rotating shaft 19 will drive the second bevel gear set 21 fixed to the outside to rotate, and the second bevel gear set 21 will drive the digging plate 23 fixed to the outside to rotate, and the digging plate 23 will eventually rotate to an inclined position, and the digging plate 23 will extend out of the main body 1 through the hole 24 opened on the outside of the main body 1. At this time, the main body 1 is rotated, and the digging plate 23 will sample the external soil, and the sampled soil can be sent into the soil storage trough 14 through the inclined digging plate 23 for easy detection.

[0039] Example 2

[0040] like Figure 1-7 As shown, based on the first embodiment, the first rotating shaft 7 and the disc 3 are rotatably connected, the fixed block 6 and the disc 3 are rotatably connected, a chute 4 is provided on the outside of the disc 3, the outside of the chute 4 is slidably connected to the first connecting block 5, the first connecting block 5 and the fixed block 6 are rotatably connected, the outside of the fourth rotating shaft 19 is fixedly connected to the first connecting plate 26, the outside of the first connecting plate 26 is fixedly mounted with a motor 25, the output end of the motor 25 and the fourth rotating shaft 19 are fixedly connected, and the outside of the first connecting plate 26 is fixedly connected to the first baffle 27;

[0041] The first baffle 27 is connected to the main body 1 in a sliding manner, the outside of the first baffle 27 is fixedly connected to the second connecting plate 29, the second connecting plate 29 is rotatably connected to the main body 1, the outside of the second connecting plate 29 is meshedly connected to the third connecting plate 30, the outside of the third connecting plate 30 is fixedly connected to the second baffle 28, the second baffle 28 is connected to the main body 1 in a sliding manner, the second bevel gear set 21 is fixedly connected to the fourth rotating shaft 19, the outside of the fourth rotating shaft 19 is fixedly connected to the first bevel gear set 20, the outside of the first bevel gear set 20 is fixedly connected to the second rotating shaft 11, the second rotating shaft 11 is rotatably connected to the main body 1, and the external transmission of the second rotating shaft 11 is connected to the belt 12;

[0042] The external transmission of the belt 12 is connected to the third rotating shaft 13, and the third rotating shaft 13 is rotatably connected to the main body 1. The outside of the third rotating shaft 13 is fixedly connected to a ratchet 32, and a pawl 31 is provided on the outside of the ratchet 32. The outside of the pawl 31 is fixedly connected to the first gear 18, and the first gear 18 is fixedly connected to the first rotating shaft 7. A water pump 8 is fixedly installed inside the main body 1, and a water pipe 9 is provided at the output end of the water pump 8. The outside of the main body 1 is fixedly connected to a drill bit 15, and the outside of the main body 1 is fixedly connected to a pull-out plate 17, and the outside of the pull-out plate 17 is fixedly connected to a detection box 16.

[0043] In this embodiment, there are multiple first connecting blocks 5 that are slidably connected to the outside of the slide groove 4, and the first connecting blocks 5 are all slidably connected to the fixed block 6, so that the fixed block 6 remains stable when rotating. When the motor 25 is started, the motor 25 drives the fourth rotating shaft 19 set at the output end to rotate, and the fourth rotating shaft 19 drives the first connecting plate 26 fixedly connected to the outside to rotate. The first connecting plate 26 drives the motor 25 fixedly connected to the outside to open to the outside. At this time, the motor 25 drives the second connecting plate 29 fixedly connected to the outside to rotate, and the second connecting plate 29 causes the third connecting plate 30 engaged with the outside to rotate, that is, the third connecting plate 30 drives the second baffle 28 to open to the outside, so that the hole 24 opened on the outside of the main body 1 can be exposed;

[0044] When the fourth rotating shaft 19 rotates, it drives the excavating plate 23 to rotate to an inclined state, so that the excavating plate 23 can be extended outside the main body 1 to take soil samples. When the fourth rotating shaft 19 rotates, it also drives the first bevel gear set 20 fixed to the outside to rotate. When the first bevel gear set 20 rotates, it drives the second rotating shaft 11 fixed to the outside to rotate. The rotation of the second rotating shaft 11 drives the belt 12 connected to the external transmission to transmit the power. The belt 12 rotates the third rotating shaft 13 connected to the external transmission. At this time, the third rotating shaft 13 drives the ratchet 32 to rotate. At this time, the pawl 31 blocks the ratchet 32, that is, the ratchet 32 drives the first gear 18 to rotate through the pawl 31, which causes the first gear 18 to drive the first rotating shaft 7 fixed to the outside to rotate, so that the storage and replacement mechanism can operate.

[0045] It is convenient to replace the new water storage tank 10 and soil storage tank 14 for sampling. When the fourth rotating shaft 19 is rotated in the opposite direction, the first baffle 27, the second baffle 28 and the excavation plate 23 can be restored to their original positions. At this time, the third rotating shaft 13 will also drive the ratchet 32 to rotate in the opposite direction, but the pawl 31 does not affect the rotation of the ratchet 32, that is, the ratchet 32 will not drive the first gear 18 to rotate through the pawl 31, which will keep the soil storage tank 14 and the water storage tank 10 unchanged and will not cause confusion in the storage replacement mechanism. When the water pump 8 is started, the water pump 8 will sample groundwater into the water storage tank 10 through the water pipe 9 for easy testing. The pull-out plate 17 arranged on the outside of the main body 1 is easy to open, which is convenient for taking out the soil storage tank 14 and the water storage tank 10 after sampling inside the main body 1. The detection box 16 is convenient for testing the soil and groundwater after sampling. The drill bit 15 is convenient for driving the device to move to different depths for sampling.
