Description
Technical Field
[0001] The present application relates to the field of pipeline detection, and in particular to a petroleum pipeline pressure detection device. Background Art
[0002] Finished oil pipelines are essential transportation equipment in industrial production. The oil they transport may be affected by the external environment and cause pressure changes. If the pipeline is in a state of too high or too low pressure, it will have a serious impact on the production process and equipment. Therefore, it is particularly important to detect the use of finished oil pipelines.
[0003] Traditional pipeline leak detection methods are usually based on pressure sensors to collect pressure signals in the pipeline and determine whether the pipeline is blocked or has a leak through pressure changes. When the pipeline is blocked, the staff uses ultrasonic detection devices to obtain physical information about the pipeline wall and determine the specific blockage location of the pipeline.
[0004] When the existing detection device detects the position of pipeline blockage, the worker holds the probe in one hand so that the probe is in contact with the outer wall of the oil pipeline, and holds the display device in the other hand. When the pipeline to be detected is long and the area is large, a larger ultrasonic detector is required. When the area to be detected is large, the worker needs to hold the probe and move it back and forth along the outer wall of the oil pipeline. The detection process consumes a lot of time, and the worker has the defect of high work intensity when detecting large pipelines. Utility Model Content

DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-4 This application is described in further detail.
[0031] The embodiment of the present application discloses a petroleum pipeline pressure detection device.
[0032] Reference Figure 1A petroleum pipeline pressure detection device includes a sleeve 1, a detection rod 2, a bracket 3, an ultrasonic detector 4 and a control component 5, wherein the bracket 3 is supported on the ground; the sleeve 1 is arranged on the upper surface of the bracket 3, and the bracket 3 can support the sleeve 1; the ultrasonic detector 4 is arranged at one end of the detection rod 2 in the length direction, and the end of the detection rod 2 away from the ultrasonic detector 4 is penetrated through the end surface of the sleeve 1 in the length direction, and the outer wall of the detection rod 2 is slidably connected to the inner wall of the sleeve 1; the ultrasonic detector 4 is connected to a power supply, and the ultrasonic detector 4 can use the difference in acoustic properties of materials and their defects to judge whether there are defects inside the oil pipeline according to the reflection of the ultrasonic propagation waveform of the oil pipeline and the energy change of the penetration time. During detection, the detection end of the ultrasonic detector 4 is brought into contact with the outer wall of the oil pipeline, and the control component 5 can drive the detection rod 2 to slide back and forth along the length direction of the sleeve 1. The detection rod 2 can automatically drive the ultrasonic detector 4 to move back and forth along the length direction of the outer wall of the oil pipeline. There is no need for the staff to manually move the detection rod 2 and the ultrasonic detector 4 back and forth. The staff can judge and detect the pressure conditions inside the oil pipeline based on the data detected by the ultrasonic detector 4, and thereby judge whether there is leakage or blockage in the oil pipeline, thereby improving the staff's detection efficiency of the oil pipeline.
[0033] Reference Figure 2 and Figure 3 The control component 5 includes an adjusting nut 51, which is rotatably arranged on the end face of the sleeve 1 away from one end in the length direction; the adjusting nut 51 is rotatably connected to the end face of the sleeve 1 close to the detection rod 2, and the detection rod 2 is threadedly connected to the adjusting nut 51; a convex ring 52 is protruding from the end of the adjusting nut 51 close to the sleeve 1, and a slide groove 11 is provided on the inner wall of the sleeve 1 close to the end of the adjusting nut 51, the convex ring 52 is buckled into the slide groove 11, and the convex ring 52 is slidably connected to the inner wall of the slide groove 11; when the adjusting nut 51 rotates circumferentially around its own axis, it can drive the detection rod 2 to reciprocate along the length direction of the sleeve 1, thereby driving the ultrasonic detector 4 to reciprocate in the direction close to or away from the sleeve 1, thereby realizing the measurement of the oil pipeline pressure.
[0034] Reference Figure 2 and Figure 3 A limiting strip 12 is convexly provided on the inner wall of the sleeve 1, and a limiting groove 21 is provided on the detection rod 2, and the extension direction of the limiting groove 21 is consistent with the length direction of the detection rod 2; the limiting groove 21 can be buckled into the limiting strip 12, and the limiting strip 12 can slide back and forth along the extension direction of the limiting groove 21; because the limiting strip 12 is buckled into the limiting groove 21, the detection rod 2 can only slide along the length direction of the sleeve 1; thereby, when the staff adjusts the position of the detection rod 2 and the ultrasonic detector 4, the possibility of the detection rod 2 rotating around its own axis in the sleeve 1 can be avoided, so that the detection end of the ultrasonic detector 4 is always in contact with the side wall of the oil pipeline.

[0037] In this embodiment, the drive motor 55 is a servo motor, which can control the speed and has very accurate position accuracy. When the signal voltage is zero, there is no self-rotation, thereby reducing the possibility of the displacement of the detection rod 2 changing due to the self-rotation of the drive motor 55.

[0039] Reference Figure 4The end of the connecting foot 322 away from the connecting tube 321 is set at a sharp angle. When the supporting foot 32 is supported on the ground, the sharp corner of the connecting foot 322 can be inserted into the ground, so that the connection between the supporting foot 32 and the ground is more stable, thereby reducing the possibility of the sleeve 1 tipping over due to shaking.

In the present embodiment, the protective cover 323 is detachably connected to the side wall of the connecting foot 322 to facilitate the staff to take and place the protective cover 323; when the detection device is not needed, the protective cover 323 is buckled on the sharp corner of the connecting foot 322, and the inner wall of the protective cover 323 is clamped with the outer wall of the connecting foot 322 to achieve the limited fixation of the protective cover 323 and the connecting foot 322, thereby reducing the possibility of accidental injury to others due to the sharp corner of the connecting foot 322 protruding from the supporting foot 32.

[0042] In this embodiment, the connecting rope 324 is made of elastic material, and the end of the connecting rope 324 away from the protective cover 323 is fixedly arranged on the end of the connecting tube 321 away from the connecting foot 322; when the connecting rope 324 is in a retracted state, the length of the connecting rope 324 is less than the distance between the connecting tube 321 and the end of the connecting foot 322 away from the connecting tube 321; when the protective cover 323 is buckled with the connecting foot 322, it is only necessary to gently pull the connecting rope 324 to stretch the protective cover 323 to the sharp corner of the connecting foot 322, and install the protective cover 323 on the end of the connecting foot 322; when the pressure detection device is in use, the protective cover 323 is removed, and the connecting rope 324 pulls the protective cover 323 to move upward, so that the protective cover 323 is suspended between the connecting foot 322 and the ground, reducing the possibility of the protective cover 323 and the connecting rope 324 being scattered on the ground, thereby improving the safety of the pressure detection equipment.
[0043] Reference Figure 4 The support platform 31 is detachably connected to the outer wall of the sleeve 1, and a limiting bolt is arranged on the support platform 31.

[0045] The implementation principle of an oil pipeline pressure detection device in an embodiment of the present application is as follows: before detection, the connecting foot 322 is rotated to adjust the height of the bracket 3 so that the detection end of the ultrasonic detector 4 can abut against the outer wall of the oil pipeline; when the output shaft of the driving motor 55 is rotated, it can drive the second gear 54 to rotate circumferentially around the axis of the second gear 54, thereby driving the first gear 53 and the adjusting nut 51 to rotate circumferentially around the axis of the adjusting nut 51, and controlling the detection rod 2 and the ultrasonic detector 4 to reciprocate along the length direction of the sleeve 1 to detect the outer wall of the oil pipeline; during the monitoring process, the staff does not need to manually move the detection rod 2 and the ultrasonic detector 4 back and forth, and the staff can judge and detect the pressure situation inside the oil pipeline based on the data detected by the ultrasonic detector 4, and thereby judge whether there is leakage or blockage in the oil pipeline, thereby improving the staff's detection efficiency of the oil pipeline.
