Description

Technical Field

[0001] The present invention relates to the technical field of crude oil production measurement, and specifically to a portable single-well crude oil production measurement device. Background Art

[0002] With the rapid development of the petroleum industry, a large number of oil production wells have been established in oil production plants under various oil companies. Restricted by the distribution of underground crude oil, these oil production wells are extremely scattered geographically, posing a severe challenge to single-well metering. After the crude oil is produced and transported through pipelines, most of them are connected with flow measurement machines on the pipelines, and the crude oil production is measured by the flow rate of crude oil in the pipelines. Generally, most crude oil production measurement devices are fixed on the crude oil transmission pipelines, and most of the measurement mechanisms included in the crude oil production measurement devices are relatively many, resulting in a relatively large overall mass of the device and making it inconvenient to move and carry the device.

[0003] When the production measurement device is placed on the ground and connected to the crude oil pipeline, when the crude oil pipeline is subjected to an external downward pressure, the crude oil pipeline will be displaced. Since the probe of the measurement device is inserted into the interior of the crude oil pipeline, when the crude oil pipeline is displaced, the connection between the measurement device and the crude oil pipeline may be damaged due to excessive pulling force, resulting in the disconnection or leakage at the connection between the pipeline and the measurement device, thus affecting the measurement of crude oil production. Summary of the Invention

[0004] The purpose of the present invention is to provide a portable single-well crude oil production measurement device to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a portable single-well crude oil production measurement device, including a main body and two connecting frames. The two connecting frames are respectively fixedly connected to the left and right sides of the main body. The bottoms of the two connecting frames are fixedly connected with a stabilizing frame. The left and right ends of the stabilizing frame far from the connecting frames are both fixedly connected with connecting rotating heads. The device further includes: A reinforcement mechanism, which is arranged on the handle frame. The reinforcement mechanism includes an L-shaped movable hole frame, which is rotatably connected to the outer wall of the handle frame. The side of the L-shaped movable hole frame far from the connecting rotating head is rotatably connected to a lower movable bracket.

[0007] Furthermore, auxiliary rollers are rotatably connected to the sides of the two connecting frames away from the main body.

A connecting rotating rod is fixedly connected between the two connecting rotating heads, and a limit lifting hole frame is fixedly connected to the outer wall of the connecting rotating rod.

[0008] Furthermore, a detection connection mechanism is arranged at the bottom of the slide hole plate. The detection connection mechanism includes two slide rods which are respectively slidably connected inside the two slide hole plates. The bottom of the slide rods is fixedly connected with a connecting plate, and the bottom of the connecting plate is fixedly connected with a connection head. Signal transmission lines are connected between the bottoms of the two connection heads and the input end of the bottom of the detection connection end. A flow transmission detection head is fixedly connected to the end of the outer wall of the connecting plate away from the slide rod. The output end of the flow transmission detection head is arranged at the bottom of the connecting plate. A signal transmission frame is fixedly connected between the two connecting plates at the end away from the flow transmission detection head.

[0009] Furthermore, the reinforcement mechanism further includes a connecting strip which is rotatably connected to the end of the outer wall of the L-shaped movable hole frame away from the connecting rotating head. The end of the connecting strip away from the L-shaped movable hole frame is rotatably connected to the end of the auxiliary roller away from the connecting frame.

[0010] Furthermore, a slide hole is opened at the connection between the L-shaped movable hole frame and the connecting rotating head, and a spring fitting frame is slidably connected to the inner wall of the slide hole on the L-shaped movable hole frame. The spring fitting frame is fitted with the outer wall of the connecting rotating head. An extrusion spring is fixedly connected to the side of the spring fitting frame away from the connecting rotating head. The lower movable bracket and the upper limit frame are both in contact with the outer wall of the crude oil pipeline.

[0011] Furthermore, the positioning mechanism further includes a card hole which is penetrated and opened on the outer wall of the end limit frame. The connection between the plug-in handle and the control rod is inserted into the through hole on the top limit hole frame, the connection between the plug-in handle and the control rod is inserted into the card hole, and the connection between the plug-in handle and the control rod is in contact with the outer wall of the extension rod.

[0012] Furthermore, a counteracting mechanism is arranged at the bottom of the connecting plate. The counteracting mechanism includes a threaded rod which is threadedly connected inside the threaded sleeve frame. The bottom of the threaded rod is rotatably connected with a rotating connection bottom frame, and slide hole strips are rotatably connected to the left and right sides of the rotating connection bottom frame.

[0013] Further, one end of the sliding hole bar away from the rotating connection base frame is rotatably connected to the outer wall of the connecting rotating rod. A strip-shaped sliding hole is provided at the connection between the sliding hole bar and the connecting rotating rod. One end of the sliding hole bar away from the rotating connection base frame is fixedly connected with a lower sliding hole bar. A support bracket is rotatably connected between the two lower sliding hole bars. The support bracket slidably penetrates through the limiting lifting hole frame. A strip-shaped sliding hole is penetrated and provided at the connection between the lower sliding hole bar and the support bracket.

[0014] The present invention has the following beneficial effects: When one end of the control rod close to the plug rack handle abuts against the outer wall of the extension rod in the present invention, the lower movable bracket will move to the bottom of the pipeline. At the same time, the upper limiting frame will abut against the outer wall of the pipeline above the pipeline. Then, the plug rack handle is inserted into the top limiting hole frame to position the control rod. When the pipeline is pressurized, through the support and limitation of the upper limiting frame and the lower movable bracket on the pipeline, the connection between the device and the connection of the pipeline and the flow transmission detection head is always kept in an integrated state during the measurement process, reducing the occurrence of the phenomenon that the connection between the crude oil pipeline and the probe of the flow transmission detection head is damaged due to excessive pulling force, and further reducing the occurrence of disconnection or leakage at the connection between the flow transmission detection head and the pipeline, thereby avoiding affecting the measurement of the crude oil output.

[0015] When the device moves in the present invention, the whole is in an inclined posture so that the moving wheels contact the ground. When the whole measuring device is pushed towards the pipeline measuring interface, the lower movable bracket will first contact the surface of the pipeline. Pull the plug rack handle on one side to separate the plug rack handle from the jack on the top limiting hole frame. When the whole device is leveled, the lower movable bracket abuts against the pipeline, which will cause the L-shaped movable hole frame to rotate on the connecting head. When the bottom of the stabilizing frame contacts the ground and the device is placed stably, the extension frame and the L-shaped movable hole frame are controlled to rotate on the connecting head through the plug rack handle and the control rod, so that the extension frame is pressed down. The lower movable bracket abuts against the outer wall of the pipeline. During the process that the L-shaped movable hole frame rotates on the connecting head and drives the extension frame to descend, the lower movable bracket slides on the outer wall of the pipeline, and at the same time, it will push the L-shaped movable hole frame to slide on the connecting head through the movable hole, and at the same time, squeeze the spring on the spring fitting frame, so as to facilitate moving the lower movable bracket under the pipeline to support the pipeline, improving the stability of the connection between the flow transmission detection head and the crude oil pipeline, and reducing the occurrence of the disconnection between the flow transmission detection head and the pipeline due to external factors during the connection detection process.

[0016] The present invention positions the insertion rack handle out of the positioning hole of the top limit hole rack, pulls the control rod to drive the L-shaped movable hole rack to rotate on the connecting swivel head. When the end of the control rod away from the extension rack moves to a position corresponding to the card hole on the end limit rack, the lower movable bracket is moved to the front of the pipeline, and the upper limit rack is separated from the outer wall of the crude oil pipeline. At the same time, the connecting bar drives the auxiliary roller to rotate on the connecting rack, so that the auxiliary roller extends outwards. After the flow transmission detection head is separated from the pipeline, by pulling the handle rack, the whole device can be tilted, making the moving wheels contact the ground. The auxiliary roller extends out of the connecting rack, and after the moving wheels contact the ground, the rollers on the auxiliary roller also contact the ground. Through the cooperation of the moving wheels and the auxiliary rollers, the distance between the moving wheels and the auxiliary rollers can ensure that the device will not completely fall after loosening the handle rack when it is tilted, thus improving the stability of the device during movement. The handle rack drives the device to move on the ground through the moving wheels and the auxiliary rollers, facilitating the movement of the device to the position of the crude oil pipeline of another oil well, and thus facilitating the carrying of the device.

[0017] After the present invention moves the device to the position of the crude oil pipeline and the lower movable bracket and the upper limit rack support the pipeline, the threaded rod rotates inside the threaded sleeve rack, and the signal connecting plate drives the two signal transmission racks to descend synchronously, so that the sliding rod slides inside the sliding hole plate, thereby driving the flow transmission detection head to move into the connecting valve of the pipeline and connect with the pipeline. During the process of the threaded rod driving the rotating connection bottom rack to descend, the end of the sliding hole strip away from the connecting rod is pressed down, so that the sliding hole on the sliding hole strip slides and rotates on one side of the outer wall of the connecting rod, driving the lower sliding hole strip to tilt upwards. Thus, the lower sliding hole strip slides and rotates on the connecting bar of the bottom of the support bracket, driving the support bracket to rise inside the limit lifting hole rack, so that the top of the support bracket abuts against the outer wall of the pipeline, increasing the support effect on the pipeline during the detection of the flow transmission detection head and improving the practicability of the device.

[0018] Of course, it is not necessary for any product implementing the present invention to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] During use, when the device is moving, it is in an inclined posture as a whole so that the moving wheels 104 are in contact with the ground. When pushing the whole measuring device towards the pipeline measuring interface, the lower movable bracket 308 will first come into contact with the surface of the pipeline. Pull one side of the inserting bracket handle 306 to separate the inserting bracket handle 306 from the jack on the top limiting hole bracket 402. When the device is leveled as a whole, the lower movable bracket 308 abuts against the pipeline, which will cause the L-shaped movable hole bracket 302 to rotate on the connecting rotating head 108. After the bottom of the stabilizing frame 107 contacts the ground and the device is placed stably, control the extension frame 303 and the L-shaped movable hole bracket 302 to rotate on the connecting rotating head 108 through the inserting bracket handle 306 and the control rod 305, so that the extension frame 303 presses down.

At the same time, the upper limiting bracket 304 will abut against the outer wall of the pipeline above the pipeline. Then insert the inserting bracket handle 306 into the top limiting hole bracket 402 to position the control rod 305. When the pipeline is pressurized, through the support and limit of the pipeline by the upper limiting bracket 304 and the lower movable bracket 308, the device is kept in an integrated connection state with the connection between the pipeline and the flow transmission detection head 204 during the measurement process, reducing the occurrence of the phenomenon that the connection between the crude oil pipeline and the flow transmission detection head 204 is damaged due to excessive pulling force, resulting in damage to the pipeline or the probe of the measuring device. Push the insertion rack handle 306 out of the positioning hole of the top limit hole rack 402, pull the control rod 305 to drive the L-shaped movable hole rack 302 to rotate on the connecting rotating head 108. When the end of the control rod 305 away from the extension rack 303 moves to a position corresponding to the clamping hole 404 on the end limit rack 403, move the lower movable bracket 308 to the front of the pipeline, and the upper limit rack 304 disengages from the outer wall of the crude oil pipeline. At the same time, drive the auxiliary roller 106 to rotate on the connecting frame 111 through the connecting bar 301, so that the auxiliary roller 106 extends outwards. After the flow transmission detection head 204 is separated from the pipeline, by pulling the handle frame 103, the whole device is tilted, the moving wheel 104 contacts the ground, and the auxiliary roller 106 extends out of the connecting frame 111. After the moving wheel 104 contacts the ground, the roller on the auxiliary roller 106 also contacts the ground. Through the cooperation of the moving wheel 104 and the auxiliary roller 106, the distance between the moving wheel 104 and the auxiliary roller 106 can prevent the device from completely falling after loosening the handle frame 103 when the device is tilted, thereby improving the stability of the device during movement; After moving the device to the position of the crude oil pipeline and the lower movable bracket 308 and the upper limit rack 304 support the pipeline, rotate the threaded rod 501 inside the threaded sleeve rack 110, drive the two signal transmission racks 203 to descend synchronously through the signal connection plate 202, and make the sliding rod 201 slide inside the sliding hole plate 105, thereby driving the flow transmission detection head 204 to move into the connection valve of the pipeline and connect with the pipeline. During the process of the threaded rod 501 driving the rotating connection bottom frame 502 to descend, drive the end of the sliding hole strip 503 away from the connecting rotating rod 109 to press down, so that the sliding hole on the sliding hole strip 503 rotates and slides on the outer wall of the connecting rotating rod 109, driving the lower sliding hole strip 504 to tilt upwards, so that the lower sliding hole strip 504 slides and rotates on the connecting bar of the bottom of the support bracket 505, driving the support bracket 505 to rise inside the limit lifting hole rack 112, so that the top of the support bracket 505 abuts against the outer wall of the pipeline, increasing the support effect on the pipeline during the detection of the flow transmission detection head 204.
