[0025] The condensing shell 1 inputs steam through the steam valve 11, the steam valve 11 is unidirectional input and can only open inward, and the condensing pipe 12 is used for circulating cooling liquid, exchanges heat with steam to condense it, and outputs for sampling detection.

[0026] The temperature control pull rod 2 comprises a temperature sensor 21, the temperature sensor 21 is fixedly connected with the outer surface of the condensing pipe 12, the top surface of the temperature sensor 21 is fixedly connected with an electric push rod 22, the outer surface of the condensing shell 1 is fixedly connected with a heat insulation shell 221, the top surface of the heat insulation shell 221 is slidingly connected with a pushing column 23, and the top surface of the pushing column 23 is hingedly connected with a connecting pull rod 24.

[0027] The electric push rod 22 is slidingly connected with the inner surface of the heat insulation shell 221, and the output end of the electric push rod 22 is fixedly connected with the pushing column 23.

[0028] Through the setting of the temperature control pull rod 2, the input amount of steam each time is controlled according to the condensing capacity of the cooling liquid. In the process of use, the temperature sensor 21 is attached to the surface of the condensing pipe 12 to detect the temperature of the cooling liquid, the outside is wrapped by the heat insulation shell 221 to reduce the influence of external air on the temperature, when the temperature of the cooling liquid rises, the electric push rod 22 is driven according to the temperature change to make the pushing column 23 rise, and the connecting pull rod 24 is used to push the extraction cylinder 3 to control the input amount of steam, and the rising distance of the electric push rod 22 is proportional to the temperature.

[0029] The extraction cylinder 3 comprises a top shell 31, the outer surface of the top shell 31 is fixedly connected with an exhaust valve 32, the bottom surface of the top shell 31 is fixedly connected with an air suction valve 321, the inner surface of the top shell 31 is slidably connected with an inner piston 33, the top surface of the inner piston 33 is hingedly connected with a piston rod 331, the top surface of the piston rod 331 is rotatably connected with a piston cam 332, the top surface of the top shell 31 is fixedly connected with a top bracket 34, the inner surface of the top bracket 34 is rotatably connected with a rotating disc 35, the outer surface of the rotating disc 35 is fixedly connected with a shaft connecting frame 351, and the outer surface of the shaft connecting frame 351 is fixedly connected with a rotating pull rod 352.

[0030] The air suction valve 321 penetrates to the inner surface of the condensing shell 1, the piston cam 332 penetrates the rotating disc 35, the rotating disc 35 is symmetrically distributed on both sides of the top bracket 34, and the rotating pull rod 352 is hingedly connected with the connecting pull rod 24.

[0031] Through the setting of the extraction cylinder 3, the piston actively extracts steam, and the steam input amount is controlled according to the condensing capacity of the cooling liquid. During use, after the steam is connected to the steam valve 11, the piston cam 332 rotates and drives the piston rod 331 and the inner piston 33 to reciprocatingly ascend and descend in the top shell 31. The exhaust valve 32 is used for one-way exhaust to the outside of the top shell 31, and the exhaust valve 32 is in communication with the outside. The air suction valve 321 is used for one-way air suction of the top shell 31, and the air suction valve 321 is in communication with the inside of the condensing shell 1. When the inner piston 33 rises, the air suction valve 321 generates negative pressure to suck steam from the steam valve 11 into the inside of the condensing shell 1. When the inner piston 33 descends, the air suction valve 321 cannot exhaust, and the gas is exhausted from the exhaust valve 32. The piston cam 332 rotates on the rotating disc 35, and the piston cam 332 is not concentric with the rotating disc 35. When the rotating disc 35 rotates in the top bracket 34, the piston cam 332 also rotates, and at this time, the position of the rotation center of the piston cam 332 changes, so that the absolute height of the top dead center is adjusted, the effective volume in the top shell 31 changes, and thus the compression ratio is changed, and the steam input amount is controlled. When the rotation center of the piston cam 332 is lower, the position of the piston reaching the top dead center is lower, and the compression ratio is reduced. Conversely, the compression ratio is increased. Since the extraction cylinder 3 needs to suck steam for condensing water for multiple times, the single input amount is reduced, and the input amount in the whole process is also reduced.

[0032] The positive input shaft 4 comprises a side shell 41 which is symmetrically distributed on both sides of the condensing shell 1, and the outer surface of the side shell 41 is fixedly connected with a gearbox 42, the input end of the gearbox 42 is fixedly connected with a driving motor 421, the output end of the gearbox 42 is fixedly connected with a bevel gear set 422, one end of the bevel gear set 422 is fixedly connected with an output shaft 43, the outer surface of the output shaft 43 is fixedly connected with an outer gear ring 431, and the inner surface of the outer gear ring 431 is meshed with an inner gear 432.

[0033] The bevel gear set 422 is composed of three mutually meshing bevel gears, the outer gear ring 431 is rotatably connected with the inner surface of the side shell 41, the inner gear 432 is fixedly connected with the piston cam 332, the outer gear ring 431 and the inner gear 432 are symmetrically distributed on both sides of the extraction cylinder 3 and are respectively connected with the positive input shaft 4 and the feedback shaft 5.

[0034] Through the setting of the positive input shaft 4, the output power drives the extraction cylinder 3, and the rotation is dispersed for timed output of condensed water. In the process of use, the driving motor 421 rotates to adjust the required rotating speed and torque output through the gearbox 42. First, the bevel gear set 422 drives one side bevel gear to rotate, and in turn drives the remaining two bevel gears to rotate. The bottom bevel gear outputs rotation to the connecting shaft 6, the side bevel gear drives the outer gear ring 431 to rotate through the output shaft 43, and the inner gear 432 is driven to rotate by the outer gear ring 431. The other end of the inner gear 432 is connected with the piston cam 332, so as to realize the effect of driving the piston cam 332 to rotate. The outer gear ring 431 is collinear with the center of the rotating disc 35, and the piston cam 332 rotates with the rotating disc 35 to change the center position, at the same time, the inner gear 432 can also rotate inside the outer gear ring 431 to follow the center position of the piston cam 332, so as to adapt to the different heights of the piston cam 332; The rotation output by the bottom bevel gear directly drives the connecting shaft 6.

[0037] By setting the feedback shaft 5, the rotation speed is adjusted according to the extraction amount of the extraction cylinder 3, for controlling the discharge time of the discharge interface 7, in the process of use, the other end of the piston cam 332 drives the inner gear 432 and the outer gear ring 431 on one side of the feedback shaft 5 to rotate, the variable speed wheels 51 are symmetrically distributed, the outer gear ring 431 on this side directly drives the adjacent variable speed wheel 51 to rotate, but there is no direct connection between the two variable speed wheels 51, so they will not rotate synchronously, through the two contact wheels 522 meshing with the surface, the contact wheel 522 will be driven to rotate when it is in contact with the variable speed wheel 51 rotating in a driven manner, and the rotation will be transmitted to the contact wheel 522 on the other side, so that the variable speed wheel 51 on the other side can rotate in a driven manner, in the initial state, the driven bracket 52 is in the middle position, both contact wheels 522 are in contact with the center of the variable speed wheel 51, the radius ratio of the meshing part is one to one, at this time the transmission ratio is one, when the piston cam 332 rises, it will lift the driven lifting block 54 upward, and pull the driven sliding block 53 backward through the traction rope 541, then the contact wheel 522 on one side moves toward the small diameter of the variable speed wheel 51, and the contact wheel 522 on the other side moves toward the large diameter of the variable speed wheel 51, at this time the radius ratio of the contact area changes, the diameter of the driven variable speed wheel 51 increases relative to the diameter of the driving variable speed wheel 51, and the transmission ratio also changes, that is, the driving variable speed wheel 51 will drive the driven variable speed wheel 51 to rotate a smaller angle, and the driven variable speed wheel 51 will change the rotation again through the bevel gear set 422 on this side and output to the connecting shaft 6 below; The driven lifting block 54 is limited in the movement path by the side limiting blocks 542 on both sides, and can only move but not rotate, the driven sliding block 53 will squeeze and stretch the reset springs 531 on both sides during movement, after the piston cam 332 resets, the reset springs 531 drive the driven sliding block 53 to reset, and the transmission ratio also returns to normal.

[0038] The connecting shaft 6 comprises a lifting groove 61, the lifting groove 61 is provided on the outer side surface of the side shell 41, the inner side surface of the lifting groove 61 is slidingly connected with a pulling block 611, the inner side surface of the side shell 41 is rotationally connected with an upper shaft 62, the bottom surface of the upper shaft 62 is provided with a linkage groove 621, the inner side surface of the side shell 41 is slidingly connected with a lower shaft 63, and the top surface of the lower shaft 63 is fixedly connected with a linkage column 631.

[0039] The pulling block 611 is rotationally connected with the outer surface of the lower shaft 63, the linkage column 631 is slidingly connected with the inner surface of the linkage groove 621, and the upper shaft 62 is fixedly connected with the bottom surface of the bevel gear set 422.

[0040] By arranging the connecting shaft 6, the connection of the two sides is controlled. In use, the bevel gear at the bottom of the bevel gear set 422 drives the upper shaft 62 to rotate. When the linkage column 631 of the lower shaft 63 is inserted into the linkage groove 621 of the upper shaft 62, the rotation of the upper shaft 62 drives the lower shaft 63 to rotate. The connection between the upper shaft 62 and the lower shaft 63 is adjusted by the pulling block 611, so as to control the rotation of the lower shaft 63.

[0041] The discharge interface 7 comprises a driving dial 71, the driving dial 71 is fixedly connected with the bottom surface of the lower shaft 63, the outer surface of the driving dial 71 is engaged with a driven groove wheel 711, the bottom surface of the driven groove wheel 711 is sleeved with a transmission belt 712, the bottom surface of the condensing shell 1 is fixedly connected with a bottom shell 72, the inner surface of the bottom shell 72 is provided with an output groove 721, the inner surface of the bottom shell 72 is rotationally connected with an inner rotating disc 73, the top surface of the inner rotating disc 73 is fixedly connected with a sealing gasket 731, and the inner surface of the condensing shell 1 is fixedly connected with an inner funnel 74.

[0042] The driving dial 71, the driven groove wheel 711 and the transmission belt 712 are all mounted on the inner surface of the bottom mounting shell 13, the driven groove wheel 711 is rotationally connected with the inner surface of the bottom mounting shell 13, and the inner rotating disc 73 is sleeved on the inner sides of the two transmission belts 712.

[0043] By arranging the discharge interface 7, the quantitative sampling or the timed sampling can be selected according to the connection of the lower shaft 63 on different sides. In use, the lower shaft 63 drives the driving dial 71 to rotate. The driving dial 71 drives the driven groove wheel 711 to rotate by one twelfth of a circle each time the driving dial 71 rotates one circle, so as to achieve the effect of deceleration and intermittent rotation. The rotation of the driven groove wheel 711 is transmitted to the inner rotating disc 73 through the transmission belt 712, so that the same rotation occurs. When the groove on the inner rotating disc 73 overlaps or aligns with the output groove 721 in the bottom shell 72, the condensed steam is output from the groove through the inner funnel 74. When the groove is not aligned, the output groove 721 is blocked by the inner rotating disc 73, and the sealing is ensured by the sealing gasket 731. The condensed water cannot be output downward. Two lower shafts 63 are respectively led out by positive input shaft 4 and feedback shaft 5, positive input shaft 4 is directly driven by driving motor 421 at constant speed, when the lower shaft 63 on this side rotates, the rotation speed of driving disc 71 is also constant, then the time of inner rotating disc 73 opening output is constant, which is used for timing sampling, while the lower shaft 63 on the side of feedback shaft 5 is the main drive, the rotation speed of this lower shaft 63 is affected by the extraction amount of extraction cylinder 3 through the speed change of feedback shaft 5, the rotation speed is also changed, the less the extraction amount of steam each time, the lower the rotation speed, the time of inner rotating disc 73 rotating to coincide is longer, so the extraction time is increased when the single extraction amount is small, and equal sampling is realized.

[0044] In the embodiment, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 Each component is installed on condensing shell 1, the inside of condensing shell 1 is used for steam condensation, and condensed water is output from the bottom; In the embodiment, as shown in Figure 5 According to the temperature change, driving electric push rod 22 drives push column 23 to rise; In the embodiment, as shown in Figure 6 、 Figure 7 Suction valve 321 of extraction cylinder 3 is installed inside condensing shell 1, air suction generates internal pressure to suck steam, and exhaust valve 32 is outside, which is used for discharging air; In the embodiment, as shown in Figure 8 、 Figure 9 Piston cam 332 is not concentric with rotating disc 35, when rotating disc 35 rotates in top support 34, piston cam 332 also rotates, at this time, the position of the rotation center of piston cam 332 changes; In the embodiment, as shown in Figure 10 、 Figure 11 The lifting of push column 23 makes piston cam 332 at different heights, and the compression ratio is changed, piston cam 332 drives inner piston 33 to lift for air suction and exhaust through rotation; In the embodiment, as shown in Figure 12 、 Figure 13 、 Figure 15 Two sides of extraction cylinder 3 are respectively connected with positive input shaft 4 and feedback shaft 5, positive input shaft 4 does not change the rotation speed, and feedback shaft 5 changes the rotation speed according to the condensing capacity; In the embodiment, as shown in Figure 14 Outer gear ring 431 is collinear with the center of rotating disc 35, when piston cam 332 rotates with rotating disc 35 to change the position of the center, inner gear 432 can also rotate inside outer gear ring 431 to follow the position of the center of piston cam 332, so as to adapt to different heights of piston cam 332; In the embodiment, as shown in Figure 16 ,Figure 17 As shown, the traction rope 541 pulls the driven slider 53 backward, and the transmission ratio is changed by changing the diameter of the contact point between the speed change wheel 51 and the contact wheel 522; In this embodiment, Figure 18 As shown, when the linkage post 631 of the lower shaft 63 is inserted into the linkage slot 621 of the upper shaft 62, the rotation of the upper shaft 62 drives the lower shaft 63 to rotate; In this embodiment, Figure 19 、 Figure 20 As shown, the lower shafts 63 on both sides rotate the inner turntable 73 through the groove pulley and belt.

[0045] The use method and advantages of the present invention: The mobile cold water circulation pure steam sampling machine works as follows: like Figures 1 to 20 As shown, when in use, steam is input through the steam valve 11, and the driving motor 421 drives the outer ring gear 431 to rotate through the bevel gear set 422, and the outer ring gear 431 drives the piston cam 332 to rotate through the internal gear 432. In the process of the piston cam 332 driving the inner piston 33 to rise and fall, steam is extracted into the interior of the condensation shell 1, and the condenser pipe 12 is used to circulate the coolant, and heat exchange with the steam to condense it; Depending on the condensation capacity of the coolant, when the temperature rises, the electric push rod 22 rises to change the rotation center of the piston cam 332, so that the amount of steam extracted each time is reduced; The connecting shaft 6 on one side is connected to the positive input shaft 4. When the upper shaft 62 on this side is connected to the lower shaft 63, the bottom active dial 71 rotates at a constant speed, so that the notch of the inner rotary disk 73 gradually aligns with the output slot 721. When the alignment occurs, output is performed to achieve timed sampling. When the feedback shaft 5 is connected to the connecting shaft 6, the rotation speed of the upper shaft 62 on this side is controlled by the air intake of the extraction cylinder 3. The smaller the single air intake, the slower the rotation speed. It takes longer for the gap of the inner turntable 73 to gradually align with the output slot 721, thereby achieving equal sampling.
