[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a multi-tube liquid suction part, the pull rod is moved upward relative to the piston rod by extending the telescopic cylinder. In this process, the second telescopic spring is extended, and then the cam ring is intermittently rotated by the intermittent rotation of the bevel gear ring. When the protrusion of the cam ring squeezes the C-shaped bracket, the blocking block loses the cover on the bottom of the sampling tube, so that the salt water mixed wine can enter the sampling tube. Then, the bottom of different sampling tubes is opened and closed by the intermittent rotation of the cam ring, so that the salt water mixed wine with different liquid levels can enter different sampling tubes, thereby increasing the sampling range; 2. By setting an intermittent shifting piece, start the motor, and make the semi-connected spur gear and the semi-connected bevel gear rotate synchronously through the operation of the motor.

With the operation of the motor, the semi-connected bevel gear is separated from the second transmission bevel gear, and the semi-connected spur gear is meshed with the transmission gear plate. At this time, the semi-connected spur gear drives the adjusting screw to rotate through the transmission gear plate, so as to move the slider down along the adjusting screw, so that the extension tube moves down with the L-shaped connecting rod, thereby changing the height of the extension tube, and then cooperating with the operation of the multi-tube liquid suction piece to make the salt water mixed wine with different liquid levels enter different sampling tubes.

[0023] In this embodiment, the telescopic cylinder 510 is started, and the support frame 501 drives the ring 531 to move upward through the extension of the telescopic cylinder 510. When the ring 531 moves upward, the pull rod 533 is driven to move upward through the first telescopic spring 530, the clamping ring 523, and the connecting plate 522. At this time, since the bottom of the sampling tube 3 is blocked by the flow blocking block 529, the pull rod 533 will move upward relative to the piston rod 524. In this process, the second telescopic spring 532 is extended, and then the bevel gear ring 525 is intermittently rotated through the operation of the intermittent shifting member, so as to make the cam ring 521 rotate intermittently.

Then, the bottom of different sampling tubes 3 is opened and closed by the intermittent rotation of the cam ring 521, so that the salt water mixed wine at different liquid levels enters different sampling tubes 3, so as to increase the sampling range. When the multiple sampling tubes 3 are full of salt water mixed wine, the support frame 501 is moved downward by controlling the contraction of the telescopic cylinder 510, and the cam ring 521 is reversed by the intermittent shifting member. At this time, the collar 531 pulls the first telescopic spring 530 to extend. When the flow blocking block 529 below the sampling tube 3 loses the cover on the bottom of the sampling tube 3, the salt water mixed wine inside the sampling tube 3 will be discharged through the U-shaped connecting tube 518 and the second one-way valve 517, so that the salt water mixed wine at different liquid levels can be detected, so as to improve the accuracy of the detection.

[0024] Please refer to Figure 3 , Figure 4 , Figure 6 , Figure 8 The liquid inlet end of the first one-way valve 509 is connected to the hose 508 , and the liquid inlet end of the second one-way valve 517 is connected to the U-shaped connecting pipe 518 .

[0025] In this embodiment: by providing this structure, when the piston rod 524 moves downward, the saline-mixed liquor inside it is discharged through the second one-way valve 517, so as to achieve a one-way flow of the saline-mixed liquor in the sampling tube 3.

[0026] Please refer to Figure 8 The inner wall diameter of the collar 531 is greater than the outer wall diameter of the piston rod 524 .

[0027] In this embodiment: this structure is provided to prevent the piston rod 524 from blocking the movement of the collar 531 when the support frame 501 moves downward, thereby improving the smoothness of the movement of the collar 531.

[0028] Please refer to Figure 5 , the diameter of the connecting pin 527 is equal to the width of the guide groove 526.

[0029] In this embodiment: by providing this structure, when the cam ring 521 rotates, the protrusion of the cam ring 521 pushes the C-shaped bracket 520 to move horizontally, thereby improving the stability of the movement of the C-shaped bracket 520.

[0030] Please refer to Figure 1 , Figure 2 , Figure 4 The intermittent shifting member includes a semi-connected spur gear 534 installed at the output end of the motor 511 and located below the side plate 4, a semi-connected bevel gear 514 is installed at the bottom of the semi-connected spur gear 534, the bottom of the side plate 4 is rotatably connected to a first transmission bevel gear 512 meshing with a bevel gear ring 525 through a rotating shaft, one end of the first transmission bevel gear 512 is installed with a second transmission bevel gear 513 meshing with the semi-connected bevel gear 514, the bottom of the side plate 4 is rotatably connected to an adjusting screw rod 505 through a bearing, a transmission gear plate 502 is installed on the adjusting screw rod 505, a slider 503 is movably sleeved on the adjusting screw rod 505, a guide rod 504 located on the side of the adjusting screw rod 505 away from the motor 511 is installed at the bottom of the side plate 4, and an L-shaped connecting rod 506 connected to an extension tube 507 is installed on one side of the slider 503.

[0031] In this embodiment, the motor 511 is started, and the semi-connected spur gear 534 and the semi-connected bevel gear 514 are rotated synchronously through the operation of the motor 511. When the semi-connected bevel gear 514 rotates to mesh with the second transmission bevel gear 513, the second transmission bevel gear 513 will drive the bevel gear ring 525 to rotate through the first transmission bevel gear 512, so as to rotate the cam ring 521. With the operation of the motor 511, the semi-connected bevel gear 514 is separated from the second transmission bevel gear 513, and the semi-connected spur gear 534 is meshed with the transmission gear plate 502. At this time, the semi-connected spur gear 534 drives the adjusting screw 505 to rotate through the transmission gear plate 502, so that the slider 503 moves downward along the adjusting screw 505, so that the extension tube 507 moves downward along with the L-shaped connecting rod 506, so as to change the height of the extension tube 507, and then cooperates with the operation of the multi-tube liquid suction piece to make the salt water mixed wine with different liquid levels enter different sampling tubes 3, so as to increase the sampling range.

[0032] Please refer to Figure 2A limit plate is provided at the bottom of the adjusting screw rod 505 , and a threaded hole matching the adjusting screw rod 505 and a through hole matching the guide rod 504 are provided on the slider 503 .

[0033] In this embodiment, by providing this structure, the slider 503 moves in the vertical direction along the adjusting screw rod 505 when the adjusting screw rod 505 rotates, thereby improving the stability of the extension tube 507 moving up and down.

[0034] Please refer to Figure 2 The half-connected spur gear 534 and the half-connected bevel gear 514 have the same orientation of the teeth.

[0035] In this embodiment, by setting this structure, the first transmission bevel gear 512 and the transmission gear plate 502 rotate alternately when the motor 511 is in operation, so as to achieve the downward movement of the extension tube 507 and the orderly operation of the multi-tube liquid-absorbing component.

[0036] Please refer to Figure 8 The piston rod 524 is a hollow structure, and a clamping plate that fits with the inner wall of the piston rod 524 is provided at the bottom of the pull rod 533.

[0037] In this embodiment, this structure is provided to prevent the pull rod 533 from separating from the piston rod 524 when the pull rod 533 moves upward relative to the piston rod 524.

[0038] In combination with the above-mentioned brine mixed wine sampling and detection device, a brine mixed wine sampling and detection method is provided, which specifically includes the following steps: S1: When sampling the salt water mixed wine in the storage tank, hold the handle 2, and then insert the extension tube 507 into the storage tank; S2: Start the motor 511, and the operation of the motor 511 causes the semi-connected spur gear 534 and the semi-connected bevel gear 514 to rotate synchronously. When the semi-connected bevel gear 514 rotates to mesh with the second transmission bevel gear 513, the second transmission bevel gear 513 drives the bevel gear ring 525 to rotate through the first transmission bevel gear 512, so as to rotate the cam ring 521. With the operation of the motor 511, the semi-connected bevel gear 514 is separated from the second transmission bevel gear 513, and the semi-connected spur gear 534 is meshed with the transmission gear plate 502. At this time, the semi-connected spur gear 534 drives the adjusting screw 505 to rotate through the transmission gear plate 502, so as to move the slider 503 downward along the adjusting screw 505. S3: Start the telescopic cylinder 510, and the support frame 501 drives the collar 531 to move upward by extending the telescopic cylinder 510. When the collar 531 moves upward, the first telescopic spring 530, the clamping ring 523, and the connecting plate 522 drive the pull rod 533 to move upward. At this time, since the bottom of the sampling tube 3 is blocked by the flow blocking block 529, the pull rod 533 will move upward relative to the piston rod 524. During this process, the second telescopic spring 532 is extended, and then the cam ring 521 is intermittently rotated by the intermittent rotation of the bevel gear ring 525. When the protrusion of the cam ring 521 squeezes the C-shaped bracket 520, When the C-shaped bracket 520 moves, the flow blocking plug 529 will move, so that the flow blocking plug 529 loses its shielding of the bottom of the sampling tube 3. At this time, the piston rod 524 moves upward relative to the sampling tube 3 through the elastic restoring force of the second telescopic spring 532, so that the salt water mixed wine in the storage tank can enter the sampling tube 3 through the extension tube 507, the hose 508, the first one-way valve 509, the guide tube 528, and the liquid blocking tank 519. After that, the bottoms of different sampling tubes 3 are opened and closed through the intermittent rotation of the cam ring 521, so that the salt water mixed wines with different liquid levels enter different sampling tubes 3, thereby increasing the sampling range; S4: When the multiple sampling tubes 3 are filled with saline wine, the support frame 501 is moved downward by controlling the contraction of the telescopic cylinder 510, and the cam ring 521 is reversed by the intermittent shifting member. At this time, the collar 531 pulls the first telescopic spring 530 to stretch. When the blocking block 529 below the sampling tube 3 loses the shielding of the bottom of the sampling tube 3, the saline wine inside the sampling tube 3 will be discharged through the U-shaped connecting tube 518 and the second one-way valve 517; S5: Then the brine mixed wine with different liquid levels can be tested.

[0039] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
