[0002] The criterion for the process of sample collection, preparation, and analysis is to conduct relevant test analyses on the collected qualified samples without damaging the representativeness of the samples. To avoid the influence of some physical or chemical changes in the samples on the final test results, there should be no sample loss and personnel contact during the sample transportation process. At the same time, due to the low degree of automation during the sample transportation process, when the sample collection barrel is transported to the monitoring equipment, it needs to be manually opened. To ensure sealing, the sample collection barrel cover has a certain weight, and manual operation is prone to high labor intensity and easy to misplace samples, resulting in inconsistent sample monitoring with the actual situation, and further leading to a decrease in monitoring accuracy.

[0032] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0033] The sample collecting bucket 3 unlocking device according to an embodiment of the present invention includes a frame 1, a conveying component 2, a sample collecting bucket 3, a horizontal moving component 4, an unlocking component 5 and a cover supporting frame 6. The conveying component 2 is arranged at the bottom of the frame 1, and the conveying component 2 is adapted to input or output the sample collecting bucket 3. The conveying component 2 is adapted to input or output the sample collecting bucket 3.

[0034] Note: There seems to be a formatting error in the original text where "[[ID=?]]" is used instead of a proper ID. I've translated it as best as possible while maintaining the integrity of the text.The horizontal movement component 4 is arranged on the top of the frame 1. The lid support frame 6 and the conveying component 2 are relatively spaced apart in the width direction of the frame 1. The unlocking component 5 is arranged on the horizontal movement component 4. The horizontal movement component 4 drives the unlocking component 5 to move in the width direction of the frame 1 so that the unlocking component 5 moves above the conveying component 2 or the lid support frame 6.

[0035] Specifically, as Figures 1 to 6 shown, the horizontal movement component 4 drives the unlocking component 5 to move in the front-back direction on the horizontal plane. The horizontal movement component 4 can be a linear guide rail 5231. The unlocking component 5 is arranged on the linear guide rail 5231. The linear guide rail 5231 enables the unlocking component 5 to move in the front-back direction so that the unlocking component 5 moves above the lid support frame 6 or the conveying component 2. When the unlocking component 5 is located above the conveying component 2, the conveying component 2 transports the sample collecting bucket 3 to below the unlocking component 5. The unlocking component 5 unlocks the sample collecting bucket 3, that is, lifts the bucket lid 32 of the sample collecting bucket. Then the horizontal transfer component moves the unlocking component 5 above the lid support frame 6. Furthermore, the unlocking component 5 releases the bucket lid 32 to place the bucket lid 32 on the lid support frame 6, realizing unlocking without manual operation.

[0036] The conveying component 2 can be a belt conveyor to input or output the sample collecting bucket 3 into or out of the frame 1. Or the conveying component 2 is a belt conveyor and a bucket pushing component 22. The belt conveyor receives the input sample collecting bucket 3, that is, receives the sample collecting bucket 3 from the previous process. Then the belt conveyor transports the sample collecting bucket 3 to the position to be pushed. At this time, the bucket pushing component 22 pushes the sample collecting bucket 3 on the input belt conveyor away to push the sample collecting bucket 3 to the output end of the conveying component 2. Then the horizontal movement component 4 is started and unlocking and sampling are performed.

[0037] The conveying component 2 and the lid removing frame are arranged at intervals in the front-back direction so that the horizontal movement component 4 moves the unlocking component 5 above the conveying component 2 or the lid removing frame in the front-back direction, avoiding interference between the bucket lid 32 and the unlocked bucket body 31.

[0038] For the sample collecting bucket 3 unlocking device of the embodiment of the present invention, by arranging the unlocking component 5, the conveying component 2 and the horizontal movement component 4, it is convenient to open the sample collecting bucket after unlocking, reducing the labor intensity and improving the monitoring accuracy. At the same time, the conveying component 2 and the lid removing frame are arranged at intervals in the front-back direction to separately place the unlocked bucket lid 32 on the lid support frame 6, avoiding interference between the unlocked bucket lid 32 and the sample collecting bucket 3. At the same time, there is no need to manually pick up or put down the bucket lid 32, avoiding cross-contamination of samples caused by manual operation and improving the monitoring accuracy.

[0039] Further, the unlocking component 5 includes a vertically moving part 51 and an unlocking part 52. The vertically moving part 51 is arranged on the horizontally moving component 4, and the unlocking part 52 is arranged on the vertically moving part 51. The vertically moving part moves in the height direction of the frame 1. The vertically moving part 51 and the unlocking part 52 are connected. The upper end of the vertically moving part 51 is arranged on the horizontally moving component 4, and the unlocking part 52 is provided at the lower end of the vertically moving part 51. The vertically moving part 51 moves in the vertical direction to drive the unlocking part 52 to move in the vertical direction, thereby grasping or lowering the barrel cover 32, so as to place the unlocked barrel cover 32 on the support frame.

[0040] In some embodiments, the unlocking part 52 includes a bottom plate 521, a driving part 522 and unlocking claws 523. The driving part 522 is provided on the bottom plate 521. The output end of the driving part 522 meshes with the unlocking claws 523. The number of the unlocking claws 523 is two, and they are relatively spaced apart in the circumferential direction of the bottom plate 521. The output end of the driving part 522 drives the two unlocking claws 523 to approach or move away from each other.

[0041] The driving part 522 is provided at the upper end of the bottom plate 521. The driving part 522 can be a stepping motor. A gear 5221 is provided at the output end of the driving part 522 to mesh with the unlocking claws 523. When the output end of the driving part 522 rotates, the unlocking claws 523 on both sides of the bottom plate 521 approach or move away from each other to grasp or release the barrel cover 32.

[0042] Further, the unlocking claw 523 includes a guide rail 5231, a rack 5232, a sliding rod 5233 and a sliding hook 5234. The rack 5232 is arranged on the guide rail 5231, and the rack 5232 meshes with the output end of the driving part 522. The rack 5232 is connected to one end of the sliding rod 5233, and the other end of the sliding rod 5233 is connected to the sliding hook 5234.

[0043] The guide rail 5231 is arranged at the upper end of the bottom plate 521, and the rack 5232 is arranged on the guide rail 5231. When the output end of the driving part 522 rotates, the rack 5232 moves on the guide rail 5231, driving the sliding rods and the sliding hooks 5234 on both sides to approach or move away from each other relatively. The sliding hooks 523 are close to or away from each other to clamp or release the barrel cover 32, thereby unlocking the barrel cover 32. The shape of the sliding hook 5234 can cooperate with the barrel cover 32, which is convenient for clamping or releasing the barrel cover 32.

[0044] The sample collection bucket 3 unlocking device of the embodiment of the present invention is provided with a guide rail 5231 and a rack 5232. The rack 5232 is used to mesh with the output end of the driving member 522. When the output end of the driving member 522 rotates, it drives the rack 5232 to reciprocate on the guide rail 5231, thereby moving the slide rods 5233 and the sliding hooks 5234 on both sides closer to or away from each other, facilitating clamping or releasing the bucket lid 32. There is no need for manual lifting or placing of the bucket lid 32, avoiding sample cross - contamination caused by manual operation.

[0045] Further, the sliding hook 5234 includes a connecting plate 52341 and a bent plate 52342. The connecting plate 52341 is connected to the bent plate 52342. The sample collection bucket 3 includes a bucket body 31 and a bucket lid 32. The bucket lid 32 is detachably placed on the top of the bucket body 31, and a bent portion 321 corresponding to the bent plate 52342 is provided on the bucket lid 32.

[0046] The connecting plate 52341 extends in the up - down direction, and the bent plate 52342 extends in the horizontal direction. The bent plate 52342 can be an arc - shaped plate, and the openings of the two arc - shaped plates are opposite, so as to clamp the bucket lid 32 when approaching each other.

[0047] At the same time, a bent portion 321 corresponding to the bent plate 52342 is provided on the bucket lid 32, facilitating the clamping or releasing of the bent portion 321 when the bent plate 52342 moves along with the connecting plate 52341, and further clamping or releasing the bucket lid 32.

[0048] In some embodiments, it further includes a limiting block and a guiding block arranged on the top of the bottom plate 521. One end of the slide rod 5233 passes through the guiding block and is connected to the sliding hook 5234.

[0049] A limiting portion corresponding to the limiting block is provided at the bottom of the rack 5232 to prevent the unlocking claw 523 from detaching from the bottom plate 521.

[0050] A protruding limiting portion is provided at the bottom of the rack 5232, and a limiting block is provided on the bottom plate 521, thereby preventing the rack 5232 from detaching from the bottom plate 521 due to inertia during movement, improving the stability of the use of the rack 5232.

[0051] In some embodiments, the unlocking component 52 further includes a magnetic component 7 and a micro - switch 8 arranged at the bottom of the bottom plate 521. The monitoring end of the micro - switch 8 faces away from the bottom plate 521.

[0052] Specifically, as Figures 1 to 6As shown, when clamping the bucket cover 32, the magnetic component 7 is activated to generate a magnetic force to magnetically adsorb the bucket cover 32. The microswitch 8 is arranged at the bottom of the bottom plate 521, and the monitoring end of the microswitch 8 faces away from the bottom plate 521. The microswitch 8 is used to determine whether the unlocking claw 523 tightly holds the bucket cover 32, avoiding unlocking failure and improving the stability and safety of unlocking. At the same time, the magnetic force generated by the magnetic component 7 can unlock the bucket cover 32 independently when the unlocking claw 523 fails. Thus, the stability of unlocking is improved.

[0053] In some embodiments, the unlocking device of the sample collecting bucket 3 further includes a first induction switch 9 and a second induction switch 10 arranged on the frame 1. The position of the first induction switch 9 on the frame 1 corresponds to the position of the input end of the conveying component 2 on the frame 1, and the position of the second induction switch 10 on the frame 1 corresponds to the position of the output end of the conveying component 2 on the frame 1.

[0054] Specifically, as Figures 1 to 6 shown, the first induction switch 9 is arranged at the upper frame 1 at the left end of the conveying component 2, and the second induction switch 10 is arranged at the upper frame 1 at the right end of the conveying component 2. When the left end of the input end of the conveying component 2 of the sample collecting bucket 3, that is, the input end, the first induction switch 9 monitors the input of the sample collecting bucket 3. At this time, the conveying component 2 is activated, that is, the conveying part 21 and the bucket pushing component are activated, to convey the sample collecting bucket 3 to the output end of the conveying component 2. Then, the second microswitch 8 monitors that the sample collecting bucket 3 is located at the output end of the conveying component 2. At this time, the unlocking component 5 is activated to unlock the sample collecting bucket 3 for subsequent sampling.

[0055] In some embodiments, the unlocking device of the sample collecting bucket 3 further includes a controller and a wireless transmission module. The controller is respectively connected to the unlocking component 5, the horizontal moving component 4, the first induction switch 9 and the second induction switch 10. For example, the controller is connected to the unlocking component 5 and the second induction switch 10. Thus, when the second induction switch 10 monitors that the sample collecting bucket 3 is located at the output end of the conveying component 2, the unlocking component 5 is activated to unlock the sample collecting bucket 3. At the same time, the controller is also connected to the microswitch 8 to determine whether the unlocking claw 523 unlocks the sample collecting bucket 3. The controller controls the movement of the unlocking component 5 after unlocking to move the bucket cover 32 to the cover supporting frame 6. The controller receives the data of the first induction switch 9 to determine whether to activate the conveying component 2. For example, when the sample collecting bucket 3 is conveyed to the input end of the conveying component 2, the first induction switch 9 monitors the input of the sample collecting bucket 3, and the controller controls the conveying component 2 to start, moving the sample collecting bucket 3 to the output end of the conveying component 2 for unlocking. The controller is connected to the wireless transmission module, and the controller can be respectively wirelessly connected to the unlocking component 5, the horizontal moving component 4, the first induction switch 9 and the second induction switch 10 through the wireless transmission module.
