Description

Technical Field

[0001] The utility model relates to the field of oil pipeline leakage detection, in particular to an oil pipeline leakage detection device. Background Art

[0002] Oil, one of the main objects of geological exploration, is a viscous, dark brown liquid, known as the "blood of industry". There are oil reserves in some areas of the upper crust. The main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. There are two theories about the formation mechanism of oil: biological sedimentation and petrochemical oil. The former is more widely accepted, believing that oil is formed by organisms in ancient oceans or lakes after a long evolution, belonging to biological sedimentation and non-renewable; the latter believes that oil is generated by carbon in the crust itself, has nothing to do with organisms, and is renewable. Oil is mainly used as fuel and gasoline, and is also the raw material for many chemical industrial products, such as solutions, fertilizers, pesticides and plastics.

[0003] There are many ways to transport oil, including pipeline transportation, road transportation, rail transportation and sea transportation. Pipeline transportation is the main way to transport oil because of its low cost, continuous transportation, high stability, no impact from the external environment and large transportation volume.

[0004] However, currently, oil pipelines are generally connected in sections. The interfaces between adjacent pipelines are more susceptible to the long-term flow and extrusion of fluids, resulting in reduced overall sealing and oil leakage in the pipeline. For this reason, oil pipeline leak detection devices are generally installed at the corresponding positions of the pipeline interfaces to assist in monitoring and alarm activities. However, the monitoring sensors currently installed are generally placed inside the devices, resulting in oil dripping onto the outside of the monitoring sensors. This makes cleaning activities inconvenient and time-consuming. Utility Model Content

[0029] Here’s how it works:

[0030] When the present oil pipeline leak detection device is to be used, firstly, the lower sealing ring 3 and the upper sealing sleeve 7 are placed at the connecting position of the adjacent oil pipeline body 8, and the locking rods 5 arranged at the four sides of the outer end of the upper sealing sleeve 7 are correspondingly inserted into the connecting blocks 4 arranged at the four sides of the outer end of the lower sealing ring 3. Finally, the locking rods 5 and the connecting blocks 4 can be locked by the locking sleeve 6, so as to ensure that the lower sealing ring 3 and the upper sealing sleeve 7 can realize efficient sealing connection activities at the connecting position of the adjacent oil pipeline body 8. When oil leakage occurs at the connecting position of the adjacent oil pipeline body 8, the oil will flow into the filling layer 9 through the flow port 10 opened in the middle of the lower end of the lower sealing ring 3 to contact the top monitoring end of the pressure sensor 11. In this way, the pressure sensor 11 will generate a pressure signal, and when the pressure sensor 11 is triggered, the alarm 2 installed on the right side of the base 1 will sound to realize the alarm reminder activity, reminding the staff that oil leakage occurs at the connecting position of the adjacent oil pipeline body 8 and maintenance activities need to be carried out in time.

[0031] In order to ensure the monitoring sensitivity of the pressure sensor 11, a convenient installation device 12 is provided inside the filling layer 9 to facilitate the disassembly and assembly of the pressure sensor 11, so that the pressure sensor 11 as a whole can be conveniently disassembled and cleaned. That is, when disassembly and cleaning activities are required, the push shaft 123 provided in the middle of the handle 122 can be squeezed to make the push shaft 123 move laterally, and the push shaft 123 can cooperate with the support bar 125 laterally plugged in the middle of the right side to achieve smooth horizontal movement, and when the push shaft 123 is squeezed, the compression spring 126 provided on the outside of the support bar 125 can also be squeezed, and with the squeezing of the push shaft 123, the transmission bar 124 vertically installed on the right side of the push shaft 123 is driven, and the transmission blocks 127 at the upper and lower ends of the transmission bar 124 are driven, so that the transmission bar 124 and the transmission blocks 127 on both sides are inclined. The inclined grooves correspondingly provided inside are transmitted correspondingly to realize the relative movement of the transmission blocks 127 on both sides. When the transmission blocks 127 on both sides move relatively, the limiting frame 128 provided at the outer end can be connected with the limiting frame 128 on the left side of the connecting frame 121 to realize stable relative or opposite movement. In this way, the transmission blocks 127 on both sides will pull the locking bars 129 installed vertically at the outer end correspondingly to simultaneously realize the plug-in locking of the locking bars 129 on both sides with the filling layer 9, so as to realize the overall unlocking activity of the connecting frame 121. In this way, the staff can move out the pressure sensor 11 provided inside the connecting frame 121 as a whole by holding the handle 122 provided on the support of the connecting frame 121 for cleaning. In this way, the pressure sensor 11 can be easily removed and cleaned without too many cumbersome steps.

[0032] When the squeezing of the push shaft 123 is released, the compressed compression spring 126 on the outer side of the support bar 125 will rebound to realize the automatic leftward push reset of the push shaft 123 and the transmission bar 124. In this way, when the subsequent connecting frame 121 is re-moved into the filling layer 9, the transmission blocks 127 on both sides can push in the opposite direction to facilitate the transmission of the locking bars 129 on both sides to reinsert into the filling layer 9, so as to realize the overall locking of the connecting frame 121, so that the pressure sensor 11 can resume the oil leakage monitoring activity;

[0033] In order to further improve the cleaning effect of the pressure sensor 11, a locking structure 12a is installed at the upper right end of the sealing baffle 1210 provided inside the connecting frame 121 to realize the convenient disassembly of the sealing baffle 1210 as a whole, so as to expose the pressure sensor 11 as a whole and improve the cleaning effect of the outside of the pressure sensor 11. That is, when it is necessary to disassemble the sealing baffle 1210, the knob 12a2 can be turned to make the knob 12a2 realize the rotation of the screw rod 12a3 connected to the bottom. As the screw 12a3 rotates, the moving block 12a4 threadedly connected to the outer side of the lower end of the screw 12a3 will move upward, and as the moving block 12a4 moves upward and downward, the moving block 12a4 is vertically fastened to the moving block 12a4. The plug-in strips 12a5 on the left and right sides of the lower end of the moving block 12a4 will move upward synchronously to release the squeezing effect on the lock shaft 12a6, so that the lock shafts 12a6 on both sides can cooperate with the stretched spring 12a8 connected to the bottom to pull, so that the lock shafts 12a6 on both sides cooperate with the support shaft 12a7 laterally plugged in at the bottom to perform synchronous lateral relative movement to release the plug-in lock with the sealing baffle 1210, so that the sealing baffle 1210 as a whole can realize convenient unlocking activities, thereby, the pressure sensor 11 connected to the middle part of the sealing baffle 1210 can be completely exposed and fully cleaned, thereby achieving the advantage of further enhancing the convenience of disassembly and cleaning of the pressure sensor 11 as a whole.

[0034] The utility model provides a petroleum pipeline leak detection device, which is provided with a convenient installation device 12, that is, the transmission bar 124 can be conveniently driven by squeezing the push shaft 123, so that the transmission bar 124 drives the transmission blocks 127 arranged at the upper and lower ends, thereby conveniently unlocking the lock bars 129 arranged on both sides and plugging and locking with the inside of the filling layer 9, so that the connecting frame 121 can be conveniently taken out of the pressure sensor 11, thereby achieving the advantage of convenient removal and cleaning of the pressure sensor 11 without too many cumbersome steps, and a locking structure 12a is provided, that is, the moving block 12a4 can be moved upward by rotating the screw rod 12a3, the squeezing effect of the plug-in bar 12a5 and the locking shaft 12a6 arranged at the bottom is released, so that the locking shafts 12a6 on both sides cooperate with the springs 12a8 arranged on both sides of the outer end of the support shaft 12a7 to realize back movement and unlocking, so that the sealing baffle 1210 can be quickly disassembled, so as to meet the full disassembly and cleaning requirements of the pressure sensor 11, thereby achieving the advantage of further enhanced convenience of overall disassembly and cleaning of the pressure sensor 11.
