[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present utility model provides a multi-sample synchronous extraction device for chemical analysis and detection, which has the following beneficial effects:

[0016] 1. For the multi-sample synchronous extraction device for chemical analysis and detection, when it is necessary to extract the liquid to be tested, the motor is started. The motor on the support block drives the first rotating rod to rotate. The first rotating rod drives the driving gear disk to rotate. When the driving gear disk rotates, it drives the driven gear disk to rotate. The driven gear disk drives the second rotating rod to rotate. Since the bottom end of the second rotating rod is provided with a thread, when the second rotating rod rotates, under the limitation of the groove, the convex block slides up and down along the inner wall of the extraction pipe, driving the piston to move upward along the inner wall of the extraction pipe. The piston drives the lifting cylinder to move along the inner wall of the extraction pipe. The bottom end of the extraction pipe extracts the liquid into the extraction pipe and enters the collection cylinder along the connecting pipe, completing the extraction of the liquid to be tested, avoiding manual multiple samplings, which may cause the staff to fatigue quickly and affect the work efficiency.

[0017] 1. When it is necessary to disassemble the collection cylinder on the box body for inspection and observation, manually press the clamping rod. The clamping rod leaves the clamping position with the collection cylinder and moves downward along the limiting rod, compressing the spring, and then the collection cylinder can be taken out for observation and inspection. After the observation and inspection are completed, the collection cylinder can be installed on the device again by using the limiting component and the limiting block, which is convenient for disassembling the collection cylinder and further improves the applicability of the device.

The motor 5 on the support block 8 will drive the first rotating rod 51 to rotate. The first rotating rod 51 drives the driving gear disk 52 to rotate. When the driving gear disk 52 rotates, it will drive the driven gear disk 53 to rotate. The driven gear disk 53 drives the second rotating rod 61 to rotate. Since the bottom end of the second rotating rod 61 is provided with a thread, when the second rotating rod 61 rotates, under the limit of the groove 66, the convex block 65 slides up and down along the inner wall of the suction pipe 6, which will drive the piston 64 to move upward along the inner wall of the suction pipe 6. The piston 64 drives the lifting cylinder 63 to move along the inner wall of the suction pipe 6.

[0030] The collection cylinder 7 is made of glass material; it is convenient to observe the liquid in the collection cylinder 7.

[0031] Working principle

[0032] When it is necessary to extract the liquid to be measured, start the motor 5. The motor 5 on the support block 8 drives the first rotating rod 51 to rotate. The first rotating rod 51 drives the driving gear disk 52 to rotate. When the driving gear disk 52 rotates, it drives the driven gear disk 53 to rotate. The driven gear disk 53 drives the second rotating rod 61 to rotate. Since the bottom end of the second rotating rod 61 is provided with threads, when the second rotating rod 61 rotates, under the limitation of the groove 66, the convex block 65 slides up and down along the inner wall of the pumping pipe 6, which drives the piston 64 to move upward along the inner wall of the pumping pipe 6. The piston 64 drives the lifting cylinder 63 to move along the inner wall of the pumping pipe 6. The bottom end of the pumping pipe 6 extracts the liquid into the pumping pipe 6 and enters the collection cylinder 7 along the connecting pipe 9, completing the extraction of the liquid to be measured. After the liquid extraction is completed, unscrew the bolt 3 on the box body 1, disassemble the mounting plate 2 from the box body 1, and then the collection cylinder 7 can be taken out from the square groove 12 by using the limiting component. When it is necessary to disassemble and inspect the collection cylinder 7 on the box body 1, manually press the clamping rod 11, the clamping rod 11 leaves the clamping position with the collection cylinder 7 and moves downward along the limiting rod 112 to compress the spring 113, then the collection cylinder 7 can be taken out for observation and inspection and taken out from the square groove 12. After the observation and inspection are completed, the collection cylinder 7 can be installed on the device again by using the limiting component and the positioning of the limiting block 10.
