The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0034] Figure 1 is a schematic diagram of a sampler 1000 according to an embodiment of the present application. Figure 1 The sampler 1000 includes a lifting rod 1100 , a sampling body 1200 , a spiral sheet bearing 1300 , a spiral sheet 1400 , and a sampling chamber 1500 .

[0035] The sampling body 1200 is a cavity structure so that a motor, a sampling push rod and other equipment can be placed in the internal structure of the sampling body 1200. According to one embodiment of the present application, the sampling body 1200 can be a cylindrical cavity structure. The spiral sheet bearing bearing 1300 includes an inner ring and an outer ring that are rotatably connected to each other, and the inner ring of the spiral sheet bearing bearing 1300 is fixedly connected to the sampling body 1200. The function of the spiral sheet bearing bearing 1300 is to enable the spiral sheet 1400 fixed to the outer ring of the spiral sheet bearing bearing 1300 to rotate relative to the sampling body 1200. The spiral sheet 1400 is spirally wound around the outside of the sampling body 1200 along the axial direction of the sampling body 1200 and is fixedly connected to the outer ring of the spiral sheet bearing bearing 1300, and the spiral sheet 1400 can rotate relative to the sampling body 1200. The lifting rod 1100 is placed along the axial direction of the sampling body 1200 and is fixedly connected to one end of the sampling body 1200 to control the lifting and lowering of the sampler 1000. The sampling chamber 1500 is connected to the other end of the sampling body 1200, and the sampling chamber 1500 can collect samples at the position where the sampler 1000 is located.

[0036] According to an embodiment of the present application, the sampler 1000 further includes a sampling bottom barrel 1600. The sampling chamber 1500 is connected to the sampling body 1200 via the sampling bottom barrel 1600, wherein one end of the sampling bottom barrel 1600 is connected to the sampling chamber 1500 by a hinge, and the sampling chamber 1500 can move relative to the sampling bottom barrel 1600. The other end of the sampling bottom barrel 1600 is fixedly connected to the sampling body 1200. According to an embodiment of the present application, the sampling bottom barrel 1600 has the same shape as the sampling body 1200, both of which are cylindrical. On the one hand, the sampling bottom barrel 1600 can expand the space for the sampling chamber 1500 to collect and store samples; on the other hand, the probe of the sample detection device can be placed in the sampling bottom barrel 1600 to realize real-time detection of the sampled sample in the sampling bottom barrel 1600.

[0037] According to an embodiment of the present application, the sampler 1000 further includes a sampling cone seat 1700, wherein the sampling cone seat 1700 is fixedly connected to the sampling body 1200, and the top surface of the sampling cone seat 1700 is fixedly connected to the lifting rod 1100. According to an embodiment of the present application, the sampling body 1200 is lifted and lowered together with the lifting rod 1100 via the sampling cone seat 1700. The sampling cone seat 1700 can be a truncated cone or a combination of a truncated cone at the top and a cylindrical shape at the bottom. According to an embodiment of the present application, the shape of the sampling cone seat 1700 is a truncated cone. The bottom surface of the sampling cone seat 1700 is fixedly connected to the sampling body 1200, and the top surface of the sampling cone seat 1700 is fixedly connected to the lifting rod 1100. When the sampler 1000 rises or falls in the sample, the shape of the sampling cone seat 1700 is conducive to reducing the resistance to the sampler 1000.

[0038] According to an embodiment of the present application, the spiral piece bearing bearing 1300 is arranged along the axial direction of the sampling body 1200, and the number thereof can be one or more. The multiple spiral piece bearing bearings 1300 include at least one driving bearing. If the spiral piece bearing bearing 1300 includes more than two driving bearings, the more than two driving bearings need to maintain the same rotation frequency and rotation direction to control the spiral piece 1400 to be able to rotate stably relative to the sampling body 1200. According to an embodiment of the present application, the spiral piece bearing bearing 1300 includes a driving bearing 1310 and a driven bearing 1320 arranged at intervals along the axial direction of the sampling body 1200. The driving bearing 1310 is connected to one end of the spiral piece 1400 to drive the spiral piece 1400 to rotate relative to the sampling body 1200. The driven bearing 1320 is used to fix the other end of the spiral piece 1400 to prevent the spiral piece 1400 from being offset relative to the sampling body 1200 when the sampler 1000 rises or falls.

[0039] According to an embodiment of the present application, the number of spiral blades 1400 can be one or more. According to an embodiment of the present application, two spiral blades 1400 with the same pitch are spirally wound around the outside of the sampling body 1200 along the axial direction of the sampling body 1200 and fixedly connected to the outer rings of the driving bearing 1310 and the driven bearing 1320. The rotation of the spiral blades 1400 in different directions is used to assist the sampler 1000 to enter or leave the sample to be sampled more effortlessly, and then reach the designated sampling position. According to an embodiment of the present application, when the spiral blade 1400 rotates clockwise, the spiral blade 1400 assists the sampler 1000 to enter the sample to be sampled and reach the designated position; when the spiral blade 1400 rotates counterclockwise, the spiral blade 1400 assists the sampler 1000 to leave the sample to be sampled after collecting the sample at the designated position. In order to better assist the sampler 1000 to enter the sample to be sampled, the lowest position of the spiral piece 1400 in the axial direction of the sampling body 1200 should be lower than the lowest position of the sampling chamber 1500, or be level with the lowest position of the sampling chamber 1500. When the sampler 1000 enters the sample to be sampled, the spiral piece 1400 enters the sample to be sampled before the sampling chamber 1500, or the spiral piece 1400 and the sampling chamber 1500 enter the sample to be sampled at the same time. The rotation of the spiral piece 1400 is used to assist the sampler 1000 to enter the sample to be sampled.

[0040] Figure 2 is a schematic diagram of the driven bearing 1320. Figure 2 The driven bearing 1320 includes an inner ring 1321 of the driven bearing and an outer ring 1322 of the driven bearing, wherein the inner ring 1321 of the driven bearing and the outer ring 1322 of the driven bearing can rotate relative to each other. According to an embodiment of the present application, the inner ring 1321 of the driven bearing and the outer ring 1322 of the driven bearing are connected by balls. According to an embodiment of the present application, the two ends of the inner ring 1321 of the driven bearing are fixedly connected to the sampling cone seat 1700 and the sampling body 1200 respectively. In order to facilitate the connection between the sampling cone seat 1700 and the inner ring 1321 of the driven bearing, an upper fixed seat can be provided between the sampling cone seat 1700 and the inner ring 1321 of the driven bearing, wherein the upper fixed seat can be a flange.

[0041] Figure 3 is a schematic diagram of the drive bearing 1310. Figure 3The driving bearing 1310 includes an inner ring 1311 of the driving bearing and an outer ring 1312 of the driving bearing. Along the axial direction of the driving bearing 1310, the outer ring 1312 of the driving bearing is longer than the inner ring 1311 of the driving bearing, so that the inner surface of the outer ring 1312 of the driving bearing can be exposed at one end of the outer ring 1312 of the driving bearing. Among them, the end of the exposed inner surface of the outer ring 1312 of the driving bearing is provided with a circle of driven gears 1314 along the circumferential direction of the outer ring 1312 of the driving bearing, so as to ensure that the outer ring 1312 of the driving bearing can obtain external power through gear transmission. The other end of the outer ring 1312 of the driving bearing is connected to the inner ring 1311 of the driving bearing through a ball, so as to ensure that the outer ring 1312 of the driving bearing can rotate relative to the inner ring 1311 of the driving bearing. The two ends of the inner ring 1311 of the driving bearing are fixedly connected to the sampling chamber 1500 and the sampling body 1200 respectively. In order to facilitate the connection between the sampling body 1200 and the inner ring 1311 of the driving bearing, a lower fixing seat may be provided between the sampling body 1200 and the inner ring 1311 of the driving bearing, wherein the lower fixing seat may be a flange.

[0042] According to an embodiment of the present application, the sampler 1000 further includes a first power source 1800, which may be an electric motor or an internal combustion engine. According to an embodiment of the present application, the first power source 1800 is an electric motor. A driving gear 1810 is fixed to the power output shaft of the first power source 1800. Figure 4 As shown, the driving gear 1810 and the driven gear 1314 are meshed with each other. The power transmitted by the first power source 1800 to the driving gear 1810 can be further transmitted to the driven gear 1314. According to an embodiment of the present application, when the first power source 1800 is working, the driving gear 1810 is driven, and the outer ring 1312 of the driving bearing is driven to rotate relative to the inner ring 1311 of the driving bearing through the meshed driven gear 1314. Further, the spiral piece 1400, one end of which is fixed to the outer ring 1312 of the driving bearing, rotates relative to the sampling body 1200. Since the other end of the spiral piece 1400 is fixedly connected to the outer ring 1322 of the driven bearing, the outer ring 1322 of the driven bearing rotates relative to the inner ring 1321 of the driven bearing driven by the spiral piece 1400. Finally, the power transmitted by the first power source 1800 is converted into the rotation of the outer ring 1312 of the driving bearing, the outer ring 1322 of the driven bearing, and the spiral piece 1400 relative to the sampling body 1200 .

[0043] The housing of the first power source 1800 is fixedly connected to the sampling body 1200. According to one embodiment of the present application, the housing of the first power source 1800 is fixed to a lower fixing seat fixedly connected to the sampling body 1200.

[0044] According to an embodiment of the present application, the spiral piece 1400 may be directly fixedly connected to the outer ring of the spiral piece bearing bearing 1300. However, in this case, when the spiral piece 1400 rotates relative to the sampling body 1200 as the spiral piece bearing bearing 1300 rotates, the sample to be sampled may rub against the spiral piece 1400 and the sampling body 1200, which may affect the service life of the sampling body 1200 and the spiral piece 1400. According to an embodiment of the present application, a spiral body 1410 may also be arranged between the spiral piece 1400 and the sampling body 1200.

[0045] Figure 5 14 is a schematic diagram of the structure of the connection between the spiral body 1410 and the spiral sheet 1400. Figure 5 The upper part of the spiral piece 1400 is spirally coiled around the outside of the spiral body 1410 and fixedly connected to the outer surface of the spiral body 1410. The spiral body 1410 is slidably sleeved on the outside of the sampling body 1200. The spiral body 1410 is fixedly connected to the outer ring of the spiral piece bearing 1300. A certain gap is left between the spiral body 1410 and the sampling body 1200 to ensure that the two can rotate relative to each other. When the outer ring of the spiral piece bearing 1300 rotates relative to the sampling body 1200, the spiral body 1410 fixedly connected to the outer ring of the spiral piece bearing 1300 drives the spiral piece 1400 to rotate relative to the sampling body 1200.

[0046] According to another embodiment of the present application, in order to avoid the wear of the sampler components due to the friction between the sample to be sampled, the two ends of the spiral body 1410 are tightly fixedly connected to the outer ring of the spiral piece bearing bearing 1300, ensuring that the sample to be sampled does not enter the gap between the spiral body 1410 and the sampling body 1200 through the interface between the two ends of the spiral body 1410 and the spiral piece bearing bearing 1300 as much as possible. According to another embodiment of the present application, in order to reduce the friction between the spiral piece 1400 and the spiral body 1410 and enhance the stability of the rotating piece 1400, the spiral piece 1400 located on the outer surface of the spiral body 1410 is set to be fixedly connected with the spiral body 1410 without a gap.

[0047] According to another embodiment of the present application, in order to enhance the stability of the spiral sheet 1400 and ensure the service life of the spiral sheet 1400, a reinforcement sheet 1420 can be added to the spiral sheet 1400 for the portion of the spiral sheet 1400 that exceeds the lower end of the spiral body 1410 in the axial direction, and a spiral support rod 1430 can be added between the spirals of the spiral sheet 1400.

[0048] Figure 6 15 is a schematic diagram of the sampling chamber 1500 when the sampling flap 1510 is closed. Figure 6The sampling chamber 1500 includes a plurality of sampling petals 1510 , a plurality of sampling connecting rods 1520 corresponding one-to-one to the plurality of sampling petals 1510 , and a sampling push rod 1530 .

[0049] The sampling chamber 1500 includes a plurality of sampling petals 1510, which form a conical shape of the sampling chamber 1500 when closed. According to one embodiment of the present application, the number of the sampling petals 1510 is 3. The plurality of sampling petals 1510 are connected to the sampling body 1200 or the sampling bottom cylinder 1600 by means of hinges to ensure that the sampling petals 1510 can move relative to the sampling body 1200 or the sampling bottom cylinder 1600, so that the sampling chamber 1500 can be in an open state. The plurality of sampling connecting rods 1520 correspond to the plurality of sampling petals 1510 one by one, and one end of each of the plurality of sampling connecting rods 1520 is movably connected to the corresponding sampling petal 1510. The function of the sampling connecting rod 1520 is to push the sampling petal 1510 outward along the direction of the sampling connecting rod 1520. According to one embodiment of the present application, the number of sampling rods 1520 is also 3. The sampling push rod 1530 is movably connected to the inside of the sampling body 1200 along the axial direction of the sampling body 1200, and one end of the sampling push rod 1530 is movably connected to the other end of each sampling rod 1520 in the plurality of sampling rods 1520. According to one embodiment of the present application, the three sampling rods 1520 are connected to one end of the sampling push rod 1530 by a three-way fork 1540. The function of the sampling push rod 1530 is to transmit power to each sampling rod 1520 at the same time.

[0050] According to an embodiment of the present application, the sampling chamber 1500 further includes a second power source, which may be an electric motor, an internal combustion engine, or an air pump. According to an embodiment of the present application, the second power source is an electric motor. The housing of the second power source is fixedly connected to the sampling body 1200. According to an embodiment of the present application, the second power source is fixedly connected to an upper fixed seat fixedly connected to the sampling body 1200.

[0051] The second power source is fixedly connected to one end of the sampling push rod 1530 away from the three-way fork 1540 along the axial direction of the sampling body 1200, and the power output shaft of the second power source is fixedly connected to the other end of the sampling push rod 1530. The power transmitted by the second power source to the sampling push rod 1530 can be simultaneously transmitted to each sampling connecting rod 1520 through the three-way fork 1540. The function of the second power source is to control the movement of the sampling push rod 1530, and then control the opening and closing of the sampling petal block 1510.

[0052] Specifically, when the sampling push rod 1530 moves downward along the axial direction of the sampling body 1200 under the power of the second power source, each sampling connecting rod 1520 pushes each sampling petal block 1510 outward along the direction of the sampling connecting rod 1520. At this time, the sampling chamber 1500 is in the process of changing from closed to open. Figure 7 This is the final state after the sampling chamber 1500 is opened. When the sampling push rod 1530 moves upward along the axial direction of the sampling body 1200 under the power of the second power source, each sampling connecting rod 1520 pulls each sampling petal block 1510 inward along the direction of the sampling connecting rod 1520, and the sampling chamber 1500 is in a state from opening to closing.

[0053] According to another embodiment of the present application, the sampling chamber 1500 may also be composed of a plurality of sampling cone blocks 1550 and a rotating rod 1560 . Figure 8 It is a schematic diagram of the sampling chamber 1500 when the sampler 1000 includes the sampling bottom cylinder 1600 and the sampling cone blocks 1550 do not overlap. At this time, the sampling chamber 1500 is in a closed state.

[0054] See also Figure 8 The sampling chamber 1500 includes a plurality of sampling cone blocks 1550, which can form a conical shape of the sampling chamber 1500 when closed. The number of sampling cone blocks 1550 can be more than two, and the center angles corresponding to the arcs of the bottom surfaces of the sampling cone blocks 1550 can be different. According to one embodiment of the present application, the number of sampling cone blocks 1550 is two, and the center angles corresponding to the arcs of the two sampling cone blocks 1550 are the same, both of which are 180°. In order to ensure that at least one sampling cone block 1550 can rotate relative to other sampling cone blocks 1550 along the circumferential direction of the bottom circle of the conical shape of the sampling chamber 1500, the diameter corresponding to the arc of the bottom surface of at least one sampling cone block 1550 is slightly smaller than the diameter corresponding to the arc of the bottom surface of other cone blocks 1550.

[0055] The sampling chamber 1500 further includes a rotating rod 1560, one end of which is fixedly connected to the rotatable sampling cone block 1550, so that the rotatable sampling cone block 1550 can rotate relative to other sampling cone blocks 1550. According to one embodiment of the present application, in order to more conveniently fix the rotatable sampling cone block 1550 with the rotating rod 1560, a rotating plate 1570 having the same diameter as the arc of the bottom surface of the rotatable sampling cone block 1550 can be provided between the sampling cone block 1550 and the rotating rod 1560. The diameter of the rotating plate 1570 is slightly smaller than the diameter of other sampling cone blocks 1550 that are not connected to the rotating rod 1560. Other sampling cone blocks 1550 that are not connected to the rotating rod 1560 are fixedly connected to the sampling body 1200.

[0056] According to another embodiment of the present application, when the sampler 1000 includes a sampling bottom cylinder 1600, a cylindrical rotating barrel 1580 may be disposed inside the sampling bottom cylinder 1600, see Fig. 9 , the rotating barrel 1580 is located between the rotating plate 1570 and the sampling chamber 1500 and is fixedly connected to the rotating plate 1570 and the rotatable sampling cone block 1550. At this time, the diameter of the rotating plate 1570 is slightly smaller than the diameter of the bottom circle of the sampling bottom cylinder 1600. The diameter of the rotating barrel 1580 is slightly smaller than the inner diameter of the sampling bottom cylinder 1600, and its diameter can be less than or equal to the diameter of the rotating plate 1570. According to one embodiment of the present application, the diameter of the rotating barrel 1580 is the same as the inner diameter of the sampling bottom cylinder 1600. The other sampling cone blocks 1550 that are not connected to the rotating rod 1560 are fixedly connected to the sampling bottom cylinder 1600.

[0057] According to an embodiment of the present application, the sampling chamber 1500 further includes a fourth power source, which may be an electric motor, an internal combustion engine, or an air pump. According to an embodiment of the present application, the fourth power source is an air pump. The housing of the fourth power source is fixedly connected to the sampling body 1200. According to an embodiment of the present application, the fourth power source transmits power to the rotating rod 1560 through a gear, and further transmits power to the sampling cone block 1550, thereby controlling the opening and closing of the sampling chamber 1500.

[0058] Specifically, under the power of the fourth power source, the rotating rod 1560 drives the rotatable sampling cone block 1550 to rotate counterclockwise or clockwise relative to other sampling cone blocks 1550 along the circumferential direction of the bottom circle of the sampling chamber 1500, and the sampling chamber 1500 changes from closed to open. Fig.10 The sampler 1000 includes a sampling base cylinder 1600, and the sampling chamber 1500 is schematically shown when the sampling cone block 1550 is completely overlapped, and the sampling chamber 1500 is in an open state. The rotating rod 1560 drives the rotatable sampling cone block 1550 to continue to rotate along the original movement direction or in the direction opposite to the original movement direction, and the sampling chamber 1500 gradually changes from the open state to the closed state.

[0059] According to the embodiment of the present application, the sampler 1000 further includes a material pusher 1900. Fig.11 The pusher 1900 includes a fifth power source, a pusher rod 1920 and a pusher sheet 1930. The pusher 1900 is used to clean the sample to be sampled that adheres to the sampler. Specifically, the fifth power source drives the pusher rod 1920 to extend, and accordingly, the pusher sheet 1930 fixedly connected to the other end of the pusher rod 1920 descends, thereby cleaning the sample to be sampled in the sampling bottom cylinder 1600.

[0060] The housing of the fifth power source is fixedly connected to the sampling body 1200. The fifth power source can be an electric motor, an internal combustion engine or an air pump. One end of the push rod 1920 is fixedly connected to the fifth power source along the axial direction of the sampling body 1200; the other end of the push rod 1920 is fixedly connected to the push piece 1930. In order to save space, the rotating rod 1560 can be set as a hollow structure, and the push rod 1920 is placed inside the rotating rod 1560, and does not contact the rotating rod 1560, and does not affect the rotation or lifting of each other. The push piece 1930 is located in the sampling bottom cylinder 1600, and is used to clean the sample to be sampled adhered to the inner wall of the sampling bottom cylinder 1600. When the sampling chamber 1500 is composed of a plurality of sampling cone blocks 1550 and a rotating rod 1560, the push piece 1930 is also located in the rotating barrel 1580, and its diameter is consistent with the inner diameter of the rotating barrel 1580. The shape of the push piece 1930 can be circular or truncated cone. According to an embodiment of the present application, the pusher 1930 is truncated in shape, the diameter of the bottom circle is the same as the inner diameter of the sampling bottom cylinder 1600, and the diameter of the top circle is slightly smaller than the diameter of the bottom circle. Such a design can ensure that the pusher rod 1920 can clean the sample to be sampled when it moves downward, and can also reduce the resistance when the pusher rod 1920 moves upward.

[0061] According to an embodiment of the present application, the sampler 1000 also includes a lifting rod 1100. The lifting rod 1100 includes a lifting main rod, a lifting shell and a third power source. One end of the lifting main rod is fixedly connected to the third power source, and the other end of the lifting main rod is fixedly connected to the sampling body 1200. The third power source can be an electric motor, an internal combustion engine or an air pump. According to an embodiment of the present application, the lifting main rod is a screw rod. The third power source drives the lifting main rod to contract or extend, and accordingly, the sampling body 1200 fixedly connected to the other end of the lifting main rod rises or falls, thereby realizing the rise or fall of the sampler 1000. According to the implementation mode of the present application, the first power source 1800, the second power source or the fourth power source, the third power source and the fifth power source operate independently, that is, the first power source 1800 independently controls the rotation of the spiral bearing 1300, the spiral body 1410 and the spiral 1400; the second power source or the fourth power source independently controls the opening and closing of the sampling chamber 1500; the third power source independently controls the rise and fall of the sampler 1000, and the fifth power source independently controls the rise and fall of the pusher 1900.

[0062] The above description is only an implementation method of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of protection involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the technical concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other.
