Detailed Description
In order to better understand the technical solutions of the present application, the present application will be further described in detail with reference to fig. 1 to 12.
Referring to fig. 1 to 8, in one embodiment of the present application, an oxygen content monitoring device of an oil gas storage and transportation system is provided, including a pipe body 1, a monitoring module 2 disposed in the pipe body 1 for monitoring the oxygen content of oil gas, and a rotary sampling and monitoring mechanism, where the rotary sampling and monitoring mechanism includes a joint 3 connecting two adjacent pipe bodies 1, at least one rotary groove 30 is disposed in the joint 3, a first rotary body 31 that rotates by using oil gas flowing power is disposed in the rotary groove 30, a sampler 4 is disposed at each of two ends of the first rotary body 31, and the monitoring module 2 is disposed in the first rotary body 31; in the rotation stroke of the first rotating body 31, when one sampler 4 is pressed by the wall of the rotating groove 30, the sampler 4 carries the oil gas sample to be detected by the monitoring module 2, and the other sampler 4 stretches into the flowing oil gas to sample.
Specifically, the pipe body 1 for conveying oil gas is generally cylindrical, the part of the inside of the joint 3 provided in this embodiment, which is used for the flow of oil gas, is also cylindrical, and the monitoring module 2 for monitoring the oxygen content in oil gas, such as an oxygen sensor, an oxygen dissolving instrument, etc., is in the prior art, the specific working principle of the pipe body 1 is not described in detail herein, the first rotating body 31 can drive itself to rotate by using the flow power of oil gas, and can be in a windmill structure or a waterwheel structure, such as a windmill, taking wind force as self rotation power, and taking water flow as self rotation power, the first rotating body 31 also uses the flow of oil gas as self rotation power, so that the first rotating body 31 needs to continuously detect the oxygen content of flowing oil gas, and the number of the rotating grooves 30 can be set according to actual needs, i.e. the number of the first rotating bodies 31 can be set according to actual needs, and the two ends of the first rotating body 31 are respectively provided with a sampler 4, so that in the rotation process of the first rotating body 31, the oil gas and the detection can be simultaneously carried out, so as to realize the real-time detection of the oxygen content of the pipe body 1.
Since the monitoring module 2 is disposed inside the first rotating body 31 in this embodiment, the positions of the two samplers 4 disposed on the same first rotating body 31 can be changed, that is, in this embodiment, when one sampler 4 enters the rotating groove 30, the groove wall of the rotating groove 30 can squeeze the sampler 4, so that the sampler 4 enters the first rotating body 31, and the oil gas sample is sent to the monitoring module 2 for oxygen content detection, and the movement of the sampler 4 can squeeze the other sampler 4, so that the other sampler 4 extends into the flowing oil gas for sampling, thereby not delaying the sampling of the flowing oil gas in the pipe body 1 while the oxygen content in the oil gas is detected in a closed manner.
In this embodiment, the oil gas flow resistance can be reduced by sampling in a rotating manner, and the rotation of the first rotating body 31 can be sampled by the sampler 4, and the other sampler 4 is used for inspection, so that the sampling and inspection are alternately and simultaneously performed, and the monitoring module 2 is positioned in the first rotating body 31 when detecting the oil gas sample, thus forming closed detection, and the oil gas flow can not wash the monitoring module 2.
Preferably, a second rotating body 32 is arranged on the rotating shaft of the first rotating body 31, the first rotating body 31 and the second rotating body 32 are arranged in a crisscross manner, a power rod 33 is slidably arranged on the second rotating body 32, one end of the power rod 33 is extruded into the second rotating body 32 by the wall of the rotating groove 30, and meanwhile, the other end of the power rod 33 stretches into oil gas, and the second rotating body 32 is driven to rotate under the action of the power of the oil gas flow so as to provide power for the rotation of the first rotating body 31.
Specifically, since two samplers 4 on the first rotating body 31 need to squeeze one of the samplers 4 into the first rotating body 31 by the wall of the rotating groove 30, and the other sampler 4 needs to squeeze the other sampler 4 to stretch into the flowing oil gas for sampling, the first rotating body 31 can achieve the above function in a straight shape, or after the first rotating body 31 is in a straight shape, the first rotating body 31 is overlapped with one straight shape in the axial direction of the rotating shaft, but the sampling and detecting of the oil gas do not need to install too many samplers 4, especially at the same place, so in the embodiment, a second rotating body 32 with the same structure as the first rotating body 31 is overlapped in the axial direction of the first rotating body 31, the first rotating body 31 and the second rotating body 32 are arranged in a crossed manner, meanwhile, the sampler 4 on the first rotating body 31 can slide, the power rod 33 on the second rotating body 32 can slide, during the rotation of the second rotating body 32, one end of the power rod 33 is pressed by the wall of the rotating groove 30, and the other end of the power rod 33 can stretch into the rotating shaft of the flowing oil gas, and then the other end of the power rod 33 rotates along the rotating shaft of the flowing oil gas.
When the first rotating body 31 continues to rotate from a state parallel to the oil gas flowing direction, the resistance of oil gas needs to be overcome to continuously rotate by utilizing the oil gas flowing power, when the first rotating body 31 is basically parallel to the oil gas flowing direction, the second rotating body 32 is basically vertical to the oil gas flowing direction, at the moment, one end of the power rod 33 is completely extruded into the second rotating body 32 by the wall of the rotating groove 30, and the other end of the power rod extends into the flowing oil gas, the second rotating body 32 provides rotating force for the first rotating body 31 to overcome the resistance of the oil gas based on the oil gas flowing power, and when one sampler 4 on the first rotating body 31 is extruded by the wall of the rotating groove 30, the other sampler 4 extends into the flowing oil gas based on the oil gas flowing power, and the other sampler 4 also rotates along the rotating shaft to provide power for the rotation of the power rod 33, so that the first rotating body 31 can continuously rotate.
Preferably, two samplers 4 located on the same first rotating body 31 are arranged on the same sliding seat 40, the sliding seat 40 is slidably arranged on the first rotating body 31, two sampling tubes 41 are symmetrically arranged at two ends inside the sliding seat 40, and the first rotating body 31 comprises two strokes based on oil gas flow power rotation strokes:
in the first stroke, one end of the sliding seat 40 is extruded by the wall of the rotary groove 30, the sampling tube 41 on the end carries the oil gas sample to gradually enter the first rotary body 31, and the sampling tube 41 on the other end gradually enters the flowing oil gas for discharging; in the second stroke, the slide 40 is not pressed by the wall of the rotary groove 30, and the sampling tube 41 on one end of the slide 40 provides the sample to the monitoring module 2 for detection, and the sampling tube 41 on the other end of the slide 40 samples.
Specifically, the sampler 4 is used for obtaining a flowing oil gas sample and inspecting the collected oil gas sample, and the sampler 4 is extruded by contacting with the wall of the rotary groove 30 every time, so that there is obviously a risk of accelerating damage, in this embodiment, the slide seat 40 is slidably disposed on the first rotating body 31, and every time the first rotating body 31 rotates, a certain end of the slide seat 40 replaces a certain sampler 4 to contact with the wall of the rotary groove 30, and the sampling tube 41 for containing the sample is protected in the slide seat 40.
When sampling oil gas, the detected oil gas sample is discharged out of the sampling tube 41 to obtain a new oil gas sample, and because the sampling and the detection of the oil gas are performed simultaneously, one sampling tube 41 needs to discharge the detected sample firstly, the other sampling tube 41 needs to send the sample to the monitoring module 2, then the sampling tube 41 samples, the sample in the other sampling tube 41 is detected, namely, the first stroke is from the parallel state of the sliding seat 40 and the oil gas flowing direction to the perpendicular state of the sliding seat 40 and the oil gas flowing direction, and the second stroke is from the perpendicular state of the sliding seat 40 and the oil gas flowing direction to the parallel state of the sliding seat 40 and the oil gas flowing direction.
Further, the sampling tube 41 is slidably disposed in the sliding seat 40, a first elastic member is connected between the sliding seat 40 and the sampling tube 41 in the sliding direction, an inner sampling port 410 and an inner discharging port 411 are disposed on the sampling tube 41, an outer sampling port 400 corresponding to each inner sampling port 410 and an outer discharging port 401 corresponding to each inner discharging port 411 are disposed on the sliding seat 40, an extrusion member 5 is disposed between the two sampling tubes 41, and the extrusion member 5 extrudes one of the sampling tubes 41 to move based on the rotating force of the first rotating body 31, so that the inner sampling port 410 on the sampling tube 41 is communicated with the corresponding outer sampling port 400 on the sliding seat 40, and the inner discharging port 411 is communicated with the corresponding outer discharging port 401 on the sliding seat 40.
Specifically, the sampling tube 41 needs to be placed separately after the oil gas sample is obtained, because the oil gas also enters the rotary groove 30, and the oil gas at the position is obviously different from the oil gas and oxygen content in the tube body 1, if the sampling tube 41 is not sealed, the oil gas in the rotary groove 30 can enter the sampling tube 41 in the rotating process, thus the detection result of the oxygen content in the oil gas is adversely affected, and after the sampling tube 41 is sealed, the sampling tube 41 needs to be opened in the detection process to enable the oil gas sample to be detected by the monitoring module 2.
In this embodiment, during the first stroke, the collected oil gas sample needs to be sealed, the oil gas in the rotary groove 30 is prevented from entering the sampling tube 41, then the extrusion piece 5 is extruded to obtain the movement of the sampling tube 41 of a new oil gas sample based on the rotating force of the first rotary body 31, and the elastic force of the first elastic member connected with the sampling tube 41 is increased, so that the inner sampling tube 410 and the inner sampling tube 411 on the sampling tube 41 are staggered with the corresponding outer sampling tube 400 and the corresponding outer sampling tube 401 on the sliding seat 40, the oil gas in the rotary groove 30 is prevented from entering the sampling tube 41, the sample in the sampling tube 41 is prevented from flowing out, the other sampling tube 41 is not extruded, the position of the other sampling tube 41 is unchanged under the elastic force of the first elastic member, namely, the inner sampling tube 410 and the inner sampling tube 411 on the other sampling tube 41 are all communicated with the corresponding outer sampling tube 400 and the outer sampling tube 401 on the sliding seat 40, namely, the inside of the other sampling tube 41 is communicated with the inside of the pipe body 1, in the process of following the first rotary body 31, the other sampling tube 41 enters the sampling tube 41, the other sampling tube 41 is prevented from flowing out, the new oil gas sample 41 is completely pushed out, and the other sampling tube 41 is completely replaced.
In the second stroke, the sampling tube 41 for storing a new oil gas sample is completely inserted into the first rotating body 31, and the other sampling tube 41 is also completely inserted into the flowing oil gas, so that the extrusion 5 removes the extrusion force of the sampling tube 41 completely inserted into the first rotating body 31 based on the rotating force of the first rotating body 31, and extrudes the other sampler 4 inserted into the flowing oil gas, under the action of the resilience force of the first elastic member, both the inner sampling tube 410 and the inner sampling tube 411 on the sampling tube 41 for storing a new oil gas sample are communicated with the corresponding outer sampling tube 400 and the outer sampling tube 401 on the sliding seat 40, the oil gas sample in the sampling tube 41 flows out to be in contact with the monitoring module 2, the monitoring module 2 detects the sample, and the sampling process of the other sampling tube 41 is also about to end (in the first stroke, the process of discharging the detected sample in the first sampling tube 41 is also in the sampling process of the sampling tube), and the old sampling tube is replaced by the first and the second stroke, namely the extrusion 5 is completely extruded and the sampling tube 41 is completely extruded in the second stroke.
The first stroke in the above process may be completed from the time when the inner sampling port 410 and the inner discharge port 411 on the sampling tube 41 storing the old sample are gradually communicated with the outer sampling port 400 and the outer discharge port 401 on the slide 40 to the time when the old sample is completely replaced with the new sample, that is, the slide 40 is not completely parallel to the oil gas flow direction to the time when the slide 40 is perpendicular to the oil gas flow direction, the second stroke may be completed from the time when the sampling tube 41 is completely filled with the new sample to the time when the inner sampling port 410 and the inner discharge port 411 on the sampling tube 41 are completely staggered with the outer sampling port 400 and the outer discharge port 401 on the slide 40, that is, the slide 40 is not completely parallel to the oil gas flow direction to the slide 40, and the extrusion member 5 starts to switch and squeeze the sampling tube 41 when the first stroke and the second stroke are alternated.
It should be noted that, since the oil gas is continuously circulated in the pipe body 1, it is impossible to realize that a completely unmixed new sample is completely sent to the detection every time, and embodiments of the present application do not pursue such effects, and embodiments of the present application pursue that the sampling is intermittently performed from the main channel through which the oil gas circulates through the sampling pipe 41 and the sample is sent to always basically grasp the basic state of the oil gas, and it is not pursued that the error problem caused by that part of the oil gas stays in the sampling area is not pursued in the prior art, and it is critical that such sampling precision in the prior art is completely enough for engineering practice.
Still further, the sampling tube 41 equally divides a plurality of sample storage cavities 412, and each sample storage cavity 412 corresponds to an inner sampling port 410 and an inner discharge port 411; specifically, the plurality of sample storage chambers 412 are provided, so that when the sampling tube 41 extends into the flowing oil gas, the flowing oil gas can be sampled in a layered manner in the radial direction of the tube body 1, and then the samples obtained by layering are respectively detected, so that the detection result of the oxygen content in the oil gas can be obtained more easily.

Specifically, when the first stroke and the second stroke are switched, the pressing seat 50 starts to press the first shaft 51 to move in the axial direction, and the first shaft 51 is separated from the initial position (the initial position is the position where the first shaft 51 is located under the action of the elastic force of the second elastic member when the pressing seat 50 does not press the first shaft 51), the elastic force of the second elastic member is increased, the first shaft 51 moves to transmit power through the transmission component, so that the second shaft 52 moves in the axial direction, the second shaft 52 drives the pressing block 53 to press a pressed block 54, so that the sampling tube 41 connected with the pressed block 54 moves in the sliding seat 40, and then the inner sampling port 410 and the inner sampling port 411 on the sampling tube 41 are gradually staggered in the outer sampling port 400 and the outer sampling port 401 corresponding to the sliding seat 40, and the pressed block 54 on the other sampling tube 41 is not pressed by the pressing block 53, and the inner sampling port 410 and the inner sampling port 411 on the sampling tube 41 are gradually communicated with the corresponding outer sampling port 400 and the outer sampling port 401 on the sliding seat 40.
When the second stroke is switched from the first stroke, the extrusion seat 50 removes the extrusion action on the first shaft rod 51, the first shaft rod 51 returns to the initial position under the action of the resilience force of the second elastic member, then the first shaft rod 51 transmits power to the second shaft rod 52 through the transmission component, the second shaft rod 52 moves to enable the extrusion block 53 to extrude the other pressed block 54, so that the sampling tube 41 connected with the pressed block 54 moves in the sliding seat 40, the inner sampling port 410 and the inner sampling port 411 on the sampling tube 41 are gradually staggered in the outer sampling port 400 and the outer sampling port 401 corresponding to the sliding seat 40, the pressed block 54 on the other sampling tube 41 is not extruded by the extrusion block 53 any more, and the inner sampling port 410 and the inner sampling port 411 on the sampling tube 41 are gradually communicated in the outer sampling port 400 and the outer sampling port 401 corresponding to the sliding seat 40 under the resilience force of the first elastic member.
Preferably, the extrusion seat 50 comprises a first horizontal section 500, an inclined section 501 and a second horizontal section 502, wherein one end of the first horizontal section 500 is connected with the lower end of the inclined section 501, the upper end of the inclined section 501 is connected with one end of the second horizontal section 502, and the other end of the first horizontal section 500 is connected with the other end of the second horizontal section 502; one end of the first shaft rod 51 is provided with a protruding block, and the protruding block directly enters the first horizontal section 500 from the first horizontal section 500 to the second horizontal section 502 through the inclined section 501 in the rotation process of the first shaft rod 51.
Specifically, the switching between the first stroke and the second stroke is: when the first horizontal segment 500 of the protruding block enters the second horizontal segment 502, the protruding block is extruded by the inclined segment 501, the protruding block drives the first shaft rod 51 to axially move, the elastic force of the second elastic piece is increased, the protruding block moves in the second horizontal segment 502, and the elastic force of the second elastic piece is kept unchanged.
The switching travel of the second travel and the first travel is as follows: the protruding block directly enters the first level from the second level section 502, the first shaft 51 loses the axial extrusion action and returns under the resilience action of the second elastic member.
Further, the first shaft 51 is provided with a first annular body 55 in an axial sliding manner, the second elastic member is fixedly connected with the first annular body 55, an axial end surface of the first annular body 55 is in friction contact with the joint 3, and in a process that the protruding block enters the second horizontal section 502 from the first horizontal section 500, a friction force between the first annular body 55 and the joint 3 is gradually increased.

Therefore, in this embodiment, when the first stroke and the second stroke are switched, in the process that the bump enters the second horizontal section 502 along the inclined section 501, the elastic force of the second elastic member increases, the elastic force thereof can squeeze the first annular body 55, so that the positive pressure between the contact surface of the first annular body 55 and the joint 3 increases, and then the friction force between the contact surface and the first annular body increases, so that the friction force forms an obstruction to the rotation of the first shaft rod 51, the purpose of slowing down the rotation speed of the first shaft rod 51 can be achieved, and therefore, when the sampling tube 41 extends into the flowing oil gas, the speed of the sampling tube 41 is not in direct proportion to the oil gas flow speed, and when the speed of the sampling tube 41 is in direct proportion to the oil gas flow speed, the rotation speed of the sampling tube 41 is slowed down, and then the flow speed of the oil gas is fast, and the detected oil gas can be obviously smoothly entered into the sampling tube 41.

Preferably, the number of the pressing blocks 53 on each second shaft 52 is two, and the pressing blocks are arranged in a staggered manner in the axial direction; specifically, since the two sampling tubes 41 on the same slide 40 are arranged in a straight line, the two pressing blocks 53 on the second shaft 52 are also arranged in a straight line in the direction, but when one of the pressing blocks 54 is pressed by the pressing block 53, the other pressing block 54 is not pressed, so that the two pressing blocks 53 need to be staggered in position in the axial direction of the second shaft 52, and the above-mentioned functions can be achieved. The arrangement of the pressing block 53 is, of course, only a preferred embodiment of the present application, but is not limited to this one way of achieving the above-described function.
In one embodiment of the present application, when the first rotating body 31 continues to rotate from a state parallel to the oil-gas flowing direction, the resistance of the oil-gas needs to be overcome to continue to rotate by utilizing the oil-gas flowing power, when the first rotating body 31 is basically parallel to the oil-gas flowing direction, the second rotating body 32 is basically perpendicular to the oil-gas flowing direction, at the moment, one end of the power rod 33 is completely extruded into the second rotating body 32 by the wall of the rotating groove 30, and the other end of the power rod also completely extends into the flowing oil-gas, and the power based on the oil-gas flowing rotates along the rotating shaft, so that the second rotating body 32 provides the rotating force for the first rotating body 31 to overcome the resistance of the oil-gas, and when the sampling tube 41 samples the flowing oil-gas, the friction between the first annular body 55 and the joint 3 needs to be increased to slow down the rotating speed of the first rotating body 31, so that the sampling tube 41 can smoothly take the oil-gas sample.
The above-mentioned first rotating body 31 overcomes the oil gas resistance and continues to rotate and needs the second rotating body 32 to provide the rotating force to realize, and when the sampling tube 41 samples, the first rotating body 31 is decelerated and needs the first annular body 55 to rub with the joint 3 to provide the resistance to realize, namely, two sets of mechanisms realize two functions.
Referring to fig. 8 to 12, in another embodiment of the present application, the second rotating body 32 and the first annular body 55 in one embodiment of the present application are replaced by a set of mechanism to achieve the above two functions, that is, an energy storage mechanism 6 is connected to one end of the first shaft 51, and when the protruding block enters the second horizontal section 502 from the first horizontal section 500, the energy storage mechanism 6 stores kinetic energy, and in the process of storing energy, the rotation of the first shaft 51 is decelerated, and when the protruding block directly enters the first horizontal section 500 from the second horizontal section 502, the energy storage mechanism 6 starts to release stored kinetic energy, and the kinetic energy drives the first shaft 51 to rotate against the oil-gas resistance.
The energy storage mechanism 6 comprises a third shaft rod 60 connected with one end of the first shaft rod 51, a first gear 61 is fixedly connected to the third shaft rod 60, a third annular body 62 is rotatably arranged on the third shaft rod 60, a first inserting rod 63 is fixedly connected to the third annular body 62, a gear ring 64 is fixedly connected to the first inserting rod 63, power is transmitted between the first gear 61 and the gear ring 64 through a second gear 65, the second gear 65 is rotatably arranged on the joint 3, a second inserting rod 66 is fixedly connected to the third shaft rod 60, the first inserting rod 63 and the second inserting rod 66 are oppositely arranged in the axial direction of the third shaft rod 60, and a spring 67 mechanism is arranged on the joint 3.
When the protruding block enters the second horizontal segment 502 from the first horizontal segment 500 and moves on the second horizontal segment 502, the second insert rod 66 is connected with the spring 67 mechanism along with the axial movement of the first shaft rod 51, the second insert rod 66 is connected with the spring 67 mechanism during the process that the protruding block passes through the inclined segment 501, and the second insert rod 66 also stores elastic potential energy for winding the spring 67 mechanism along with the rotation of the third shaft rod 60 (when the second insert rod 66 winds the spring 67 mechanism along with the rotation of the third shaft rod 60, the first shaft rod 51 drives the first gear 61 to rotate, the first gear 61 drives the second gear 65 to rotate, the second gear 65 drives the gear ring 64 to rotate, the gear ring 64 drives the first insert rod 63 to rotate, if the second insert rod 66 rotates anticlockwise, the first gear 61 rotates anticlockwise, the second gear 65 rotates clockwise, the gear ring 64 rotates clockwise, the first plunger 63 rotates clockwise and the second plunger 66 rotates counterclockwise, so that the tightening direction of the spring 67 is the same as the rotation direction of the first shaft 51 and counterclockwise during the up-force process, the tightening of the spring 67 tends to block the clockwise rotation of the first plunger 63, the first plunger 63 needs to be separated from the spring 67 during the connection of the second plunger 66 and the spring 67, i.e. the first plunger 63 is separated from the spring 67 during the tightening of the spring 67 before the rotation of the first plunger 63 is blocked, the first plunger 63 is separated from the spring 67, the spring 67 stores elastic potential energy to generate a reverse force to the rotation of the third shaft 60, the rotation speed of the third shaft 60 decreases, the rotation speed of the first shaft 51 decreases, the rotation speed of the first rotating body 31 decreases, the result is a reduced rotational speed of the slide 40 so that the sampling tube 41 can successfully take the oil and gas sample and provide sufficient time for the monitoring module 2 to detect the oil and gas sample.
When the protruding block directly enters the first level from the second level section 502, the second inserting rod 66 is quickly separated from the spring 67 mechanism, then the first inserting rod 63 is also quickly connected with the spring 67 mechanism, the spring 67 mechanism releases elastic potential energy to drive the gear ring 64 to rotate through the first inserting rod 63, the first gear ring 64 drives the second gear 65 to rotate, the second gear 65 drives the first gear 61 to rotate, and the first gear 61 drives the first shaft 51 to rotate.
Because the first shaft lever 51 rotates to drive the spring 67 mechanism to store elastic potential energy through the second inserting rod 66, the tightening direction of the spring 67 in the spring 67 mechanism is consistent with the rotation direction of the first shaft lever 51, and the loosening direction of the spring 67 mechanism is opposite to the rotation direction of the first shaft lever 51 when the spring 67 mechanism releases the elastic potential energy, so that the rotation direction of the gear ring 64 is also clockwise, the rotation direction of the gear ring 64 is clockwise, the rotation direction of the gear ring 64 drives the second gear 65 to be clockwise, the first gear 61 is anticlockwise, the first shaft lever 51 rotates anticlockwise to maintain the previous rotation direction, the first rotary body 31 is driven by the first shaft lever 51 to overcome the resistance of oil gas flow, and the sliding seat 40 is driven to rotate, so that two sampling tubes 41 on the same sliding seat 40 sample oil gas and the oil gas sample are respectively taken into the first rotary body 31 for detecting the oxygen content.
