Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, in particular to a sampling device for measurement and detection. Background Art

[0002] Sampling devices are divided into solid sampling and liquid sampling. For liquid sampling devices, common ones such as sampling devices used for water quality testing are further divided into manual sampling and machine sampling. The advantage of manual sampling is that it is convenient for storage and has high flexibility. The disadvantage is that it is not convenient to sample water quality at different depths. Machine sampling can take water quality at different depths, but the later storage remains unchanged, and due to the influence of the large size of the machine equipment, it can accommodate fewer water quality samples.

[0003] In order to ensure the accuracy of water quality test results, sufficient sample volume should be ensured each time sampling is carried out. Then, the samples should be measured and extracted according to the object of water quality test, and different tests should be carried out. In this process, when conventional sampling equipment collects multiple groups of water quality samples, the storage capacity of the equipment is limited, which makes it inconvenient to collect multiple groups of water quality at different depths and locations. The collected samples need to be collected and sorted manually in a timely manner, which is inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a sampling device for measurement and detection to solve the problems raised in the above-mentioned background technology.

The collection buckets after collection are transported to the hanging assembly through the guidance of the central column and stored on the hanging assembly. New collection buckets can be replenished in time to collect multiple groups of water quality. The storage is convenient and there is no need to frequently organize the collected samples.

[0006] Furthermore, the guide assembly also includes an electric plug, which is slidably installed inside the central column and slides out from the bottom of the rotating cylinder. A bottom plate is fixed to the bottom of the electric plug, and the bottom plate is in extrusion contact with the bottom of the slider on one side of the collection bucket.

[0007] Furthermore, a clamping block is provided on the top of the base plate, and the clamping block is in squeeze contact with the top of the slider of the collection bucket. A third electric push rod is fixed between the clamping block and the base plate. The positions of the base plate and the clamping block are in the same straight line with the downward notch of the circular slide rail.

[0008] Furthermore, second electric push rods are fixed at equal intervals on the outer surface of the rotating cylinder, and a socket is opened on the inner surface of the slider corresponding to the extended end of the second electric push rod, and the second electric push rod is slidably inserted into the slider.

[0009] Furthermore, a vertical slide groove is provided on the surface of the central column corresponding to the suspension assembly, and a screw is installed inside the vertical slide groove through a bearing and a built-in motor for rotation. A push plate is provided at the bottom of the rotating cylinder, and the push plate is threadedly sleeved on the screw, and the push plate is in extrusion contact with the bottom of the slider.

[0010] Furthermore, a plurality of return springs are fixed between the bottom of the push plate and the rotating cylinder, a vertical slide rail is fixed at the position of the annular slide rail corresponding to the vertical slide groove, and the sliders on both sides of the collection barrel slide along the vertical slide groove and the vertical slide rail respectively.

[0011] Furthermore, a tooth plate is fixed on the middle surface of the vertical slide rail, and a gear is rotatably installed on the side frame outside the collection barrel. The gear is fixedly connected to the collection barrel, and the gear is meshed with the tooth plate through the middle position of the vertical slide rail.

[0014] Furthermore, suspension brackets are fixed at equal intervals on the chain surface of the sprocket chain device, the insertion columns are fixed on both sides of the suspension brackets, the vertical slide rails and the center column are provided with translation gaps parallel to the insertion columns, a first electric push rod is fixed on the outer side of the circular slide rail, and the extended end of the first electric push rod is fixedly connected to the horizontal plate.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention maintains stability by fixing the fixed column of the plug board on the ground and two movable columns. The circular slide rail can be brought closer to the water surface by the adjustable length performance of the fixed column and the movable column.

[0017] 2. According to the present invention, when the collection bucket moves upward along the vertical slide rail and the vertical slide groove of the center column, the first electric push rod pushes the cross plate to move outward along the plug plate, and the sprocket chain device is away from the circular slide rail. The purpose of this is to make the collection bucket flip over through the meshing of the gear and the tooth plate when it moves along the vertical slide rail, so that the suction port faces upward. At this time, a certain flipping space is required, and the sprocket chain device moves outward to drive the already suspended collection bucket to move outward without interfering with the flipping of the new collection bucket. After the flipping of the collection bucket is completed, the sprocket chain device is pulled to the vicinity of the circular slide rail by the first electric push rod, and the cross plate moves along the ground through the movable columns at the bottom of both ends. At this time, the plug column of the suspension frame just corresponds to the translation notch and the slider of the collection bucket. With the drive of the sprocket chain device, the plug column is horizontally inserted into the inside of the slider, and then the collection bucket is pushed away by the push of the suspension frame.

[0018] 3. After collecting samples, the collection barrel of the present invention is rotated to the elevated position. At this time, the extended end of the second electric push rod is retracted, and the screw is driven to rotate by the motor built into the center column. The push plate cooperates with the thread to move in the vertical direction, and at the same time pushes the slider to slide along the vertical slide groove. The sliders on both sides of the collection barrel slide upward along the vertical slide groove and the vertical slide rail respectively. When it moves to the middle position, the gear of the side frame engages with the tooth plate to drive the collection barrel to flip 180 degrees, and the suction port opens upward to facilitate the delivery of samples.

[0019] 4. According to the present invention, as the rotating drum rotates, the collection bucket moves along the circular slide rail to the collection station. At this position, the outer slider of the collection bucket corresponds to the downward notch of the circular slide rail, which facilitates the downward movement of the collection bucket. The inner slider of the collection bucket is located between the bottom plate and the clamping block, and the clamping block is driven downward by the third electric push rod to clamp the slider. At the same time, the extended end of the second electric push rod is retracted to release the connection between the rotating drum and the collection bucket. After the hook is manually connected to the hanging ring of the piston rod, the collection bucket is driven to be inserted into the water surface by extending the electric plug column. At the same time, the electric reel-in seat synchronously unwinds the pull rope. After reaching a certain depth, the electric reel-in seat rewinds the pull rope, and the pull rope pulls the movement of the piston rod to draw water into the collection bucket through the suction port. Then the collection bucket returns and is reconnected to the rotating drum and continues to rotate to the next lifting station.

[0020] 5. Compared with the prior art, the present invention arranges the collection buckets in a ring under the guidance and drive of the circular slide rail and the central column, and collects water quality at different depths in turn. The collection buckets after collection are transported to the hanging assembly through the guidance of the central column and stored on the hanging assembly. New collection buckets can be added in time to collect multiple groups of water quality. The storage is convenient and there is no need to frequently organize the collected samples.

The collection bucket 21 is inserted into the water together with the electric plug column 312. The depth of descent and the depth of water quality collection are adjusted according to the extended length of the electric plug column 312. Then the collection bucket 21 is retracted and rotated to the lifting station, moving upward along the center column 31, cooperating with the suspension assembly 4, and stored on the outside of the chain of the sprocket chain device 46. New collection buckets 21 are continuously added from the addition port 11, so that water quality at different positions and different depths can be collected separately.

[0033] In this embodiment, second electric push rods 311 are fixed at equal intervals on the outer surface of the rotating cylinder 310, and a socket is opened on the inner surface of the extended end of the slider 24 corresponding to the second electric push rod 311, and the second electric push rod 311 is slidably inserted into the slider 24.

The movable end of the pull rope 35 is fixed with a hook 36. The outer end of the piston rod 25 is fixed with a hanging ring 26, and the hook 36 is buckled inside the hanging ring 26. As the rotating cylinder 310 rotates, The collecting bucket 21 moves along the circular slide rail 1 to the collecting station. At this position, the outer slider 24 of the collecting bucket 21 corresponds to the downward notch of the circular slide rail 1, which facilitates the downward movement of the collecting bucket 21. The inner slider 24 of the collecting bucket 21 is located between the bottom plate 313 and the clamping block 314. The clamping block 314 is driven downward by the third electric push rod 315 to clamp the slider 24. At the same time, the extended end of the second electric push rod 311 is retracted to release the connection between the rotating cylinder 310 and the collecting bucket 21. After the hook 36 is manually connected to the hanging ring 26 of the piston rod 25, the collecting bucket 21 is driven to be inserted into the water surface by the extension of the electric plug column 312. At the same time, the electric reel seat 34 synchronously unwinds the pull rope 35. After reaching a certain depth, the electric reel-in seat 34 rewinds the pull rope 35. The pull rope 35 pulls the movement of the piston rod 25, and the water is drawn into the collection bucket 21 through the suction port 22. Then the collection bucket 21 returns and is reconnected with the rotating cylinder 310, and continues to rotate to the next lifting station. In this structure, the cooperation between the electric plug column 312 and the center column 31 is actually a common electric push rod structure, and the center column 31 has a motor that independently drives the rotating cylinder 310 to rotate. The collection bucket 21 fed from the addition port 11 moves along the circular slide rail 1 through the connection between the second electric push rod 311 and the slider 24.

[0034] In this embodiment, a vertical slide groove 32 is provided on the surface of the central column 31 corresponding to the suspension component 4, and a screw 37 is installed inside the vertical slide groove 32 through a bearing and a built-in motor. A push plate 38 is provided at the bottom of the rotating cylinder 310, and the push plate 38 is threadedly sleeved on the screw 37. The push plate 38 is in extrusion contact with the bottom of the slider 24. A plurality of return springs 39 are fixed between the bottom of the push plate 38 and the rotating cylinder 310. A vertical slide rail 13 is fixed at the position of the annular slide rail 1 corresponding to the vertical slide groove 32. The sliders 24 on both sides of the collection bucket 21 slide along the vertical slide groove 32 and the vertical slide rail 13 respectively. A tooth plate 15 is fixed on the middle surface of the vertical slide rail 13. The side frame 23 on the outside of the collection bucket 21 A gear 27 is installed on the rotation, and the gear 27 is fixedly connected to the collection bucket 21. The gear 27 is meshed with the tooth plate 15 at the middle position of the vertical slide rail 13. After collecting the sample, the collection bucket 21 is rotated to the elevated position. At this time, the extended end of the second electric push rod 311 is retracted, and the screw 37 is driven to rotate by the motor built into the center column 31. The push plate 38 cooperates with the thread to move in the vertical direction, and at the same time pushes the slider 24 to slide along the vertical slide groove 32. The sliders 24 on both sides of the collection bucket 21 slide upward along the vertical slide groove 32 and the vertical slide rail 13 respectively. When it moves to the middle position, the gear 27 of the side frame 23 meshes with the tooth plate 15 to drive the collection bucket 21 to flip one hundred and eighty degrees, and the suction port 22 opens upward to facilitate the delivery of samples.

[0035] In this embodiment, the suspension assembly 4 also includes an insert plate 42, the insert plate 42 is inserted into the interior of the horizontal plate 41 for sliding movement, and the insert plate 42 is fixedly connected to the circular slide rail 1, a fixed column 43 is fixed to the bottom of the outer end of the insert plate 42, and a movable column 44 is fixed to the bottom of both sides of the horizontal plate 41, and the fixed column 43 and the movable column 44 are both telescopic rod structures, and a suspension frame 47 is fixed equidistantly on the chain surface of the sprocket chain device 46, and the insert column 48 is fixed on both sides of the suspension frame 47, and the vertical slide rail 13 and the center column 31 are parallel to the position of the insert column 48. A translation notch 14 is provided, and a first electric push rod 12 is fixed to the outside of the circular slide 1, and the extended end of the first electric push rod 12 is fixedly connected to the horizontal plate 41. The device is fixed to the ground by a fixed column 43 of the plug-in plate 42 and two movable columns 44 to maintain stability. The circular slide 1 can be brought closer to the water surface by the adjustable length performance of the fixed column 43 and the movable column 44. When the collection bucket 21 moves upward along the vertical slide 13 and the vertical slide groove 32 of the center column 31, the first electric push rod 12 pushes the horizontal plate 41 to move outward along the plug-in plate 42, The sprocket chain device 46 is away from the circular slide rail 1. The purpose of this is that when the collection bucket 21 moves along the vertical slide rail 13, it is turned over by the engagement of the gear 27 with the toothed plate 15, so that the suction port 22 faces upward. At this time, a certain turning space is required. The sprocket chain device 46 moves outward to drive the already suspended collection bucket 21 to move outward without interfering with the turning of the new collection bucket 21. After the collection bucket 21 is turned over, the sprocket chain device 46 is pulled to the vicinity of the circular slide rail 1 by the first electric push rod 12, and the horizontal plate 41 is moved at the bottom of both ends. The moving column 44 moves along the ground. At this time, the plug column 48 of the suspension frame 47 just corresponds to the translation gap 14 and the slider 24 of the collection bucket 21. With the drive of the sprocket chain device 46, the plug column 48 is horizontally inserted into the slider 24. Then, the collection bucket 21 is pushed away by the push of the suspension frame 47. The slider 24 is separated from the vertical slide rail 13 and the vertical slide groove 32 of the center column 31 along the translation gap 14. In this solution, the slider 24 not only has a socket corresponding to the second electric push rod 311 on the inside, but also has a socket for inserting the plug column 48 on the outside.

[0036] When the device is used, the collection buckets 21 are placed one by one into the annular slide rail 1 from the feeding port 11. As the rotating cylinder 310 at the bottom of the central column 31 rotates, as the rotating cylinder 310 rotates, the collection bucket 21 moves along the annular slide rail 1 to the collection station. At this position, the outer slider 24 of the collection bucket 21 corresponds to the downward notch of the annular slide rail 1, which facilitates the downward movement of the collection bucket 21. The inner slider 24 of the collection bucket 21 is located between the bottom plate 313 and the clamping block 314. The clamping block 314 is driven downward by the third electric push rod 315 to clamp the slider 24. At the same time, the extended end of the second electric push rod 311 is retracted to release the connection between the rotating cylinder 310 and the collection bucket 21. After the hook 36 is manually connected to the hanging ring 26 of the piston rod 25, the electric plug column 3 is used to connect the hook 36 to the hanging ring 26 of the piston rod 25. 12 extends, driving the collection bucket 21 to penetrate the water surface. At the same time, the electric reel-in seat 34 unwinds the pull rope 35. After reaching a certain depth, the electric reel-in seat 34 rewinds the pull rope 35. The pull rope 35 pulls the movement of the piston rod 25, and the water is pumped into the collection bucket 21 through the suction port 22. Then the collection bucket 21 returns and is reconnected with the rotating cylinder 310, and continues to rotate to the next lifting station. After collecting the sample, the collection bucket 21 is rotated to the lifting station. At this time, the extended end of the second electric push rod 311 is retracted, and the screw 37 is driven to rotate by the motor built into the center column 31. The push plate 38 cooperates with the thread to move in the vertical direction, and at the same time pushes the slider 24 to slide along the vertical slide groove 32. The sliders 24 on both sides of the collection bucket 21 slide along the vertical slide grooves respectively. 32 and the vertical slide rail 13 slide upward. When it moves to the middle position, the gear 27 of the side frame 23 engages with the tooth plate 15 to drive the collection bucket 21 to flip 180 degrees, and the suction port 22 opens upward to facilitate the delivery of samples. When the collection bucket 21 moves upward along the vertical slide rail 13 and the vertical slide groove 32 of the center column 31, the first electric push rod 12 pushes the cross plate 41 to move outward along the insert plate 42, and moves the sprocket chain device 46 away from the circular slide rail 1. The purpose of this is to flip the collection bucket 21 along the vertical slide rail 13 through the engagement of the gear 27 and the tooth plate 15, so that the suction port 22 faces upward. At this time, a certain flipping space is required, and the sprocket chain device 46 moves outward to drive the suspended collection bucket 21 to move outward. The movement will not interfere with the flipping of the new collection bucket 21. After the collection bucket 21 is flipped, the sprocket chain device 46 is pulled to the vicinity of the circular slide rail 1 by the first electric push rod 12, and the horizontal plate 41 moves along the ground through the movable columns 44 at the bottom of both ends. At this time, the plug column 48 of the suspension frame 47 just corresponds to the translation gap 14 and the slider 24 of the collection bucket 21. With the drive of the sprocket chain device 46, the plug column 48 is horizontally inserted into the slider 24, and then the collection bucket 21 is pushed away by the push of the suspension frame 47. The slider 24 is separated from the vertical slide rail 13 and the vertical slide groove 32 of the center column 31 along the translation gap 14, and new collection buckets 21 are continuously added from the addition port 11, so that water quality at different positions and different depths can be collected separately.
