Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic heaters, in particular to an oilfield pipeline electromagnetic heater. Background Art

[0002] In the cold winter, oilfield pipelines are easily affected by severe cold weather, resulting in ice accumulation inside the pipelines. This ice accumulation can block the pipelines, causing oil wells to stop production and may even cause pipeline ruptures. Furthermore, crude oil concentrations are high, so oil well production needs to maintain a certain temperature to ensure that the wells can produce oil normally. If the temperature of the oil well is too low, the oil will condense in the pipeline, thereby clogging the pipeline. Heating oilfield pipelines can avoid problems caused by low temperatures, such as pipeline corrosion, and therefore electromagnetic heaters are needed to heat the oilfield pipelines to prevent the oil from condensing and clogging the inside of the oilfield pipelines due to low temperatures, causing damage to the oilfield pipelines.

[0003] When using existing electromagnetic heaters, a pipeline is usually passed through the interior of the electromagnetic heater for heating. During use and observation, it was found that when the pipeline moves, it will collide with the interior of the electromagnetic heater, which will damage the electronic components inside the electromagnetic heater and thus affect the working performance of the electromagnetic heater. Therefore, an oilfield pipeline electromagnetic heater is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: an electromagnetic heater for oil field pipelines described in the present invention comprises a heat insulation plate, an electromagnetic heating device is fixedly connected to the inner side of the heat insulation plate, an L-shaped plug is slidably connected to the inner side of the heat insulation plate, a heat conducting plate is fixedly connected between the L-shaped plugs, a telescopic plate is fixedly connected to the inner side of the heat conducting plate, there are two pairs of telescopic plates, one pair of the telescopic plates is fixedly connected to the outer side of the first connecting plate, and the other pair of the telescopic plates is fixedly connected to the outer side of the second connecting plate, the first connecting plate is threadedly connected to a fixed screw rod, and the outer side of the heat insulation plate is fixedly connected to a docking block. This step is achieved by setting a heat conducting plate. The plate prevents the electromagnetic heating device from directly contacting the oilfield pipeline, so that when facing a pipeline made of special materials, the electromagnetic heating device can also heat it without damaging it, thereby improving the versatility of the device. By arranging the first connecting plate and the second connecting plate, when the oilfield pipeline is inserted between the telescopic plates, the telescopic plates can be moved to fit closely to the outer wall of the oilfield pipeline, and then the first connecting plate and the second connecting plate are driven to move to alignment by the expansion of the telescopic plates, and then the fixed screw is screwed into the inner side of the first connecting plate and the second connecting plate, thereby reducing direct contact between the pipeline and the electromagnetic heating device, and reducing the collision of the pipeline with the electromagnetic heating device when the pipeline moves.

[0006] Preferably, a reinforcement hoop is slidably connected to the outer side of the heat insulation plate, and a reinforcement bolt is threadedly connected to the inner side of the reinforcement hoop, and the heat insulation plate and the L-shaped plug plate are both threadedly connected to the reinforcement bolt. In this step, by arranging the reinforcement hoop and the reinforcement bolt, the structure between the L-shaped plug plates can be connected and separated from the structure outside the L-shaped plug plates, so that when the heat insulation plate and the electromagnetic heating device fail, they can be separated from the L-shaped plug plates and removed for easy disassembly, replacement and maintenance, thereby improving the convenience of device maintenance.

[0007] Preferably, a connecting sealing groove is provided on the inner side of the insulation board, and a connecting sealing plate is fixedly connected to the outer side of the insulation board. In this step, by setting the connecting sealing groove and the connecting sealing plate, when the insulation boards are docked, the connecting sealing plate can be inserted into the inner side of the connecting sealing groove, thereby further sealing the docking point and improving the sealing performance of the device.

[0008] Preferably, a mounting plate is fixedly connected to the outside of the heat insulation board, an adjusting screw is rotatably connected to the inside of the mounting plate, and a positioning pin is threadedly connected to the outside of the adjusting screw. This step is performed by setting the mounting plate, the adjusting screw and the positioning pin. When the device is installed, the positioning pin can be moved to a suitable position by rotating the adjusting screw to facilitate adjustment of the height of the device after it is fixed, making it easier for the devices to be docked, thereby improving the convenience of device installation.

[0009] Preferably, a limiting plate is slidably connected to the inner side of the mounting plate, and the limiting plate is fixedly connected to the positioning pin. In this step, by setting the limiting plate, the positioning pin will not rotate as the adjustment screw rotates, so that the positioning pin can move stably, thereby improving the stability of the device.

[0010] Preferably, slots are provided on the surface of the limiting plate and the inner side of the mounting plate, and a pin is slidably connected to the inner side of the slot. In this step, by setting the slot and the pin, when the positioning pin is moved to the appropriate position, the pin can be inserted into the mounting plate and the inner side of the limiting plate to further fix the position of the positioning pin, thereby improving the stability of the device installation.

[0011] The utility model is beneficial in that:

[0012] 1. The present invention provides a heat conducting plate to prevent direct contact between the electromagnetic heating device and the oilfield pipeline. Thus, even when facing pipelines made of special materials, the electromagnetic heating device can heat them without damaging them, thereby improving the versatility of the device. By providing a first connecting plate and a second connecting plate, when the oilfield pipeline is inserted between the telescopic plates, the telescopic plates can be moved until they are in close contact with the outer wall of the oilfield pipeline. The expansion of the telescopic plates then drives the first and second connecting plates to move until they are aligned. The fixed screw is then screwed into the inner sides of the first and second connecting plates, thereby reducing direct contact between the pipeline and the electromagnetic heating device and minimizing the risk of collision with the electromagnetic heating device when the pipeline moves.

[0013] 2. The utility model provides a reinforcing hoop and a reinforcing bolt so that the structure between the L-shaped plug-in plates can be connected to and separated from the structure outside the L-shaped plug-in plates, so that when the insulation board and the electromagnetic heating device fail, they can be separated from the L-shaped plug-in plates and removed for disassembly, replacement and maintenance, thereby improving the convenience of device maintenance.

In this step, by setting the heat conducting plate 4, the electromagnetic heating device 2 and The oilfield pipeline will not be in direct contact, so when facing a pipeline made of special materials, the electromagnetic heating device 2 can also heat it without damaging it, thereby improving the versatility of the device. By setting the first connecting plate 6 and the second connecting plate 7, when the oilfield pipeline is inserted between the telescopic plates 5, the telescopic plates 5 can be moved to be close to the outer wall of the oilfield pipeline, and then the expansion of the telescopic plates 5 drives the first connecting plate 6 and the second connecting plate 7 to move to alignment, and then the fixed screw 8 is screwed into the inner side of the first connecting plate 6 and the second connecting plate 7, thereby reducing the direct contact between the pipeline and the electromagnetic heating device 2, and reducing the collision of the pipeline with the electromagnetic heating device 2 when the pipeline moves.

[0024] Further, such as Figure 1 As shown, the outer side of the heat insulation board 1 is slidably connected with a reinforcement hoop 10, and the inner side of the reinforcement hoop 10 is threadedly connected with a reinforcement bolt 11. The heat insulation board 1 and the L-shaped plug board 3 are both threadedly connected with the reinforcement bolt 11. In this step, by arranging the reinforcement hoop 10 and the reinforcement bolt 11, the structure between the L-shaped plug boards 3 can be connected and separated from the structure outside the L-shaped plug boards 3, so that when the heat insulation board 1 and the electromagnetic heating device 2 fail, they can be separated from the L-shaped plug boards 3 and removed for easy disassembly, replacement and maintenance, thereby improving the convenience of device maintenance.

[0025] Further, such as Figure 2 and Figure 3As shown, a connecting sealing groove 12 is provided on the inner side of the insulation board 1, and a connecting sealing plate 13 is fixedly connected to the outer side of the insulation board 1. In this step, by setting the connecting sealing groove 12 and the connecting sealing plate 13, when the insulation boards 1 are docked, the connecting sealing plate 13 can be inserted into the inner side of the connecting sealing groove 12, thereby further sealing the docking point and improving the sealing performance of the device.

[0029] Working principle: put the device on the outside of the oilfield pipeline, then pull the telescopic plate 5 to move the telescopic plate 5 to close to the oilfield pipeline. At the same time, the telescopic plate 5 drives the first connecting plate 6 and the second connecting plate 7 to move, so that the first connecting plate 6 and the second connecting plate 7 can be moved to align, and then screw the fixed screw 8 into the inside of the first connecting plate 6 and the second connecting plate 7 to make the telescopic plate 5 close to the oilfield pipeline, and then rotate the adjusting screw 15 to drive the positioning pin 16 to move to the appropriate height by adjusting the screw 15, and then insert the positioning pin 16 When maintenance is needed, the device is first separated from other devices, and the reinforcing bolt 11 is turned to unscrew the reinforcing bolt 11 from the inside of the L-shaped plug plate 3. Then, the pin 19 is pulled out of the slot 18 on the inside of the limiting plate 17. Then, the positioning pin 16 is pulled out from the ground, and then the heat insulation board 1 is pulled so that the heat insulation board 1 drives the electromagnetic heating device 2 away from the L-shaped plug plate 3 until it is removed, and then it can be repaired and replaced.
