Description

Technical Field

[0001] This utility model relates to the field of oil leak monitoring technology, specifically an oil leak monitoring device at the junction of oil pipelines. Background Technology

[0002] During the transportation of oil, a large number of oil pipelines are required. However, since the required oil pipelines are relatively long, it is necessary to connect the various pipelines. During the transportation of oil, leakage is prone to occur at the pipeline junctions. When oil pipelines leak, it is easy to waste oil if it cannot be detected in time. Therefore, monitoring devices are often installed at the oil pipeline junctions for monitoring.

[0003] Chinese patent application CN221694719U discloses a pipeline leak collection device to prevent oil dripping. The device includes a pipeline and a collection box. The two pipeline interfaces are connected by flanges. The collection box is nailed to the ground below the pipeline. A collection pipe passes through and is nailed to the top opening of the collection box. An arc-groove block is installed on the top of the collection pipe, and the flange is located in the recess of the arc-groove block. When the flange connection is loose, leaking oil drips into the arc-groove block. Simultaneously, because the oil adheres to dust on the flange or in the air, it is filtered through an arc-shaped perforated plate and an arc-shaped mesh plate before dripping into the arc-groove block. Finally, it enters the collection box through the collection pipe. During maintenance, the collection box is removed, and the oil is sucked out by connecting a suction pipe to a pump pipe. This effectively avoids resource waste and safety hazards caused by oil leaks during periods when leaks are not detected.

[0004] However, the pipeline oil leak detection devices disclosed above generally have limited flexibility and cannot automatically trigger the alarm device when an oil leak occurs. There is a lack of a gravity collection device that can trigger the alarm device. Utility Model Content

[0005] The purpose of this invention is to provide an oil leak monitoring device at the junction of oil pipelines, in order to solve the problems of existing pipeline oil leak detection devices having limited degrees of freedom, failing to automatically trigger alarm devices when oil leaks occur, and lacking a gravity collection device that can trigger alarm devices.

[0006] To achieve the above objectives, the technical solution of this utility model is: an oil leak monitoring device at the junction of an oil pipeline, used at the connection of the oil pipeline, comprising a first mounting frame and a second mounting frame spliced ​​together, the first mounting frame and the second mounting frame being detachably mounted on the outer wall of the oil pipeline; a sensor is installed on the inner wall of the first mounting frame, and a first alarm light is provided on the outer wall of the first mounting frame; an oil drain port is provided on the side of the second mounting frame facing the direction of gravity, and a mounting base is provided on the outer wall of the oil drain port, the inner wall of the mounting base having a telescopic cavity, and a collecting cylinder being movably installed in the telescopic cavity; a second alarm light is also installed on the outer wall of the second mounting frame; when crude oil overflowing from the oil pipeline connection falls into the collecting cylinder, the second alarm light is triggered.

[0007] As a further embodiment of this utility model: a first threaded seat is provided on both outer walls of the first mounting frame, and a second threaded seat is provided on both outer walls of the second mounting frame; the first threaded seat and the second threaded seat are locked together by a locking clamp; a locking platform is provided at the end of the locking clamp, and the two locking platforms are fixed by bolts.

[0008] As a further embodiment of this utility model: a limiting protrusion is provided at one end of the collecting cylinder away from the direction of gravity, and a plurality of reset members are connected to the bottom of the limiting protrusion. The collecting cylinder is movably disposed in the telescopic cavity through the reset members.

[0009] As a further improvement of this utility model: multiple first electrode plates are installed on the inner wall of the telescopic cavity on the side opposite to the direction of gravity, and multiple second electrode plates are installed on the outer wall of the limiting protrusion ring on the side facing the direction of gravity.

[0010] As a further improvement of this utility model: the bottom of the collecting cylinder is detachably fitted with a bottom cover, and the outer wall of the bottom cover is provided with multiple protrusions.

[0011] As a further improvement of this utility model, solar panels are installed on the outer walls of both the first and second mounting frames.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention uses two independent first and second mounting frames to quickly install the device at the oil pipeline connection. When the leaking crude oil is small, the collection cylinder and the second alarm light will not be triggered; instead, the first alarm light will be triggered by the sensor. When the leaking crude oil is large, the collection cylinder will trigger the second alarm light under gravity. At this time, the second and first alarm lights will sound synchronously, allowing operators to distinguish the severity of the leak based on the alarm lights. This design improves the effectiveness of the oil leak monitoring device at the oil pipeline junction. Attached Figure Description

[0016] This utility model provides an improved oil leak monitoring device at the junction of oil pipelines, such as... Figures 1-4 As shown, the connection point for the oil pipe 1 includes a first mounting frame 2 and a second mounting frame 3 that are spliced ​​together. The first mounting frame 2 and the second mounting frame 3 are detachably mounted on the outer wall of the oil pipe 1. A sensor 9 is installed on the inner wall of the first mounting frame 2, and a first alarm light 10 is provided on the outer wall of the first mounting frame 2. An oil drain port 11 is provided on the side of the second mounting frame 3 facing the direction of gravity. A mounting base 12 is provided on the outer wall of the oil drain port 11. A telescopic cavity 13 is opened on the inner wall of the mounting base 12, and a collection cylinder 14 is movably installed in the telescopic cavity 13. A second alarm light 21 is also installed on the outer wall of the second mounting frame 3. When crude oil overflowing from the connection point of the oil pipe 1 falls into the collection cylinder 14, the second alarm light 21 is triggered.

[0017] In this embodiment: the invention uses two independent sets of first mounting frames 2 and second mounting frames 3 to quickly install the device at the connection of the oil pipeline 1. When the leaked crude oil is small, the collection cylinder 14 and the second alarm light 21 will not be triggered. At this time, under the action of sensor 9, the first alarm light 10 is triggered. When the leaked crude oil is large, the collection cylinder 14 will trigger the second alarm light 21 under the action of gravity. At this time, the second alarm light 21 and the first alarm light 10 will alarm synchronously. The operator can distinguish the severity of the leak based on the alarm lights. This design improves the working effect of the oil leak monitoring device at the oil pipeline junction.

[0018] See appendix Figure 1 and attached Figure 4 The first mounting frame 2 has a first threaded seat 4 on both outer walls and the second mounting frame 3 has a second threaded seat 5 on both outer walls; the first threaded seat 4 and the second threaded seat 5 are locked together by a locking clamp 6; the end of the locking clamp 6 is provided with a locking platform 7, and the two locking platforms 7 are fixed by bolts 8.

[0021] In this embodiment: when the oil pipe 1 only leaks slightly, the very small amount of crude oil will not trigger the second alarm light 21, and will only trigger the first alarm light 10 under the action of sensor 9.

[0022] See appendix Figure 2 - Appendix Figure 3 Multiple first electrode plates 17 are installed on the inner wall of the telescopic cavity 13 on the side away from the direction of gravity, and multiple second electrode plates 18 are installed on the outer wall of the limiting protrusion ring 15 on the side facing the direction of gravity.

[0023] In this embodiment: when the leaked crude oil falls into the collection cylinder 14, the collection cylinder 14 moves downward relative to the telescopic cavity 13 under the action of gravity. At this time, the first electrode 17 and the second electrode 18 are in contact, the internal circuit (not shown) is open, and the second alarm light 21 is turned on.

[0024] See appendix Figure 1 - Appendix Figure 2 The bottom of the collecting cylinder 14 is detachably fitted with a bottom cover 19, and the outer wall of the bottom cover 19 is provided with multiple protrusions 20.

[0025] In this embodiment: When the collection cylinder 14 is full of crude oil, a detachable threaded bottom cover 19 is designed for easy processing. A protrusion 20 structure is also designed to facilitate rotation of the bottom cover 19.

[0026] When the crude oil in the collection cylinder 14 is discharged, the collection cylinder 14 returns to its original position under the action of the reset component 16. At this time, the first electrode 17 and the second electrode 18 are separated, the internal circuit (not shown) is disconnected, and the second alarm light 21 is turned off.
