Abstract

The invention discloses a self-friction heat generating type oil pipeline antifreeze device, which belongs to the field of oil pipeline antifreeze. The invention utilizes external wind energy to drive a vertical axis windmill and a magnetic adjustment plate to rotate. Through the continuous rotation of the magnetic adjustment plate, the magnetic force between the magnetic adjustment plate and the heat generating ring changes repeatedly in a cycle, so that a pair of heat generating rings close to the magnetic adjustment plate continuously move back and forth. At the same time, because there is an equal magnetic force between adjacent heat generating rings, the movement of one heat generating ring breaks the magnetic force balance between the heat generating rings, so that the other heat generating rings move under the change of magnetic force, and realizes the friction movement of one to drive many. A large amount of heat energy is generated through the continuous friction between the first friction ring and the second friction ring and the heat generating ring. In addition, the heat generating ring also generates friction heat inside itself during the movement process. The two forms of friction heat are used to heat the heat transfer fluid through heat to heat it up, so as to realize the continuous spontaneous heat preservation and antifreeze effect on the oil pipeline.

Description

Technical Field

[0001] The invention relates to the field of petroleum pipeline antifreeze, and more specifically to a self-friction heat generating type petroleum pipeline antifreeze device. Background Art

[0002] In today's rapidly developing society, energy is an indispensable resource. Oil is a naturally stored energy source. The extraction of oil requires drilling, oil smelting, and then transportation to various stations for use. Oil is transported through oil pipelines, and various oil pipelines form a transportation network to transport oil to various places where it is needed.

[0003] Oil pipelines are installed outdoors. If the temperature is too low, especially in the winter in the north, the temperature is basically below zero. Oil pipelines are prone to cracks at low temperatures, which may cause oil leakage. In addition, low temperatures may easily cause oil to solidify on the inner wall of the pipeline, affecting the transportation efficiency. Therefore, antifreeze of oil pipelines is particularly important. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a self-friction heat-generating oil pipeline antifreeze device, which utilizes external wind energy to drive the vertical axis windmill and the magnetic adjustment plate to rotate. Through the continuous rotation of the magnetic adjustment plate, the magnetic force between the magnetic adjustment plate and the heat generating ring changes cyclically and repeatedly, so that a pair of heat generating rings close to the magnetic adjustment plate continuously move back and forth. At the same time, because there is an equal magnetic force between adjacent heat generating rings, the movement of one heat generating ring breaks the magnetic force balance between the heat generating rings, so that the other heat generating rings move under the change of magnetic force, thereby realizing a friction movement of one to bring many. A large amount of heat energy is generated by the continuous friction between the first friction ring and the second friction ring and the heat generating ring. In addition, the heat generating ring also generates friction heat inside itself during the movement process. The two forms of friction heat are used to heat the heat transfer fluid through heat to heat it up, thereby realizing a continuous spontaneous insulation and antifreeze effect on the oil pipeline.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A self-friction heat generating oil pipeline antifreeze device comprises an antifreeze pipe fixedly connected to the outer surface of the oil pipeline, a vertical axis windmill is arranged on the upper side of the antifreeze pipe, an inner cavity is opened inside the antifreeze pipe, the inner cavity is filled with heat transfer fluid, a magnetic adjustment plate is arranged inside the inner cavity, an extension rod is fixedly connected to the upper end of the magnetic adjustment plate, the extension rod passes through the upper end of the antifreeze pipe and is rotatably connected to the inside of the antifreeze pipe, the vertical axis windmill comprises a vertical shaft, the lower end of the vertical shaft is sleeved on the outer side of the extension rod, and a bolt assembly is connected between the vertical shaft and the extension rod, a plurality of heat generating rings are arranged inside the inner cavity, and the plurality of heat generating rings are evenly distributed on the left and right sides of the magnetic adjustment plate, a first friction ring is fixedly connected to the inner wall of the inner cavity away from the oil pipeline, a second friction ring is fixedly connected to the inner wall of the inner cavity close to the oil pipeline, and one of the inner walls of the inner cavity is fixedly connected to the second friction ring. The side walls are fixedly connected with side magnetic sheets. The present invention utilizes external wind energy to drive the vertical axis windmill and the magnetic adjustment plate to rotate. Through the continuous rotation of the magnetic adjustment plate, the magnetic force between the magnetic adjustment plate and the heat generating ring changes repeatedly, so that a pair of heat generating rings close to the magnetic adjustment plate continuously move back and forth. At the same time, because there is equal magnetic force between adjacent heat generating rings, the movement of one heat generating ring breaks the magnetic balance between the heat generating rings, so that the other heat generating rings move under the change of magnetic force, realizing the friction movement of one to bring many. A large amount of heat energy is generated by the continuous friction between the first friction ring and the second friction ring and the heat generating ring. In addition, the heat generating ring also generates friction heat inside itself during the movement. The two forms of friction heat are used to heat the heat transfer fluid through heat to achieve continuous spontaneous insulation and antifreeze effect on the oil pipeline.

[0009] Furthermore, the heat generating ring includes a main heat conducting ring and a secondary heat conducting ring, the main heat conducting ring is located on the outside of the secondary heat conducting ring, a pair of fixed nets are fixedly connected between the main heat conducting ring and the secondary heat conducting ring, the main heat conducting ring is fixedly connected to a third friction ring on the outer surface close to the first friction ring, and the secondary heat conducting ring is fixedly connected to a fourth friction ring on the inner surface close to the second friction ring. When the heat generating ring slides back and forth inside the inner cavity, the third friction ring will rub back and forth with the first friction ring, and the fourth friction ring will rub back and forth with the second friction ring, and the mechanical energy will be converted into heat energy generated in the friction process, and the heat energy will then be absorbed by the heat conducting fluid in the inner cavity, so that the temperature of the heat conducting fluid increases, thereby playing a role in heat preservation and antifreeze for the oil pipeline inside the antifreeze pipe.

[0010] Furthermore, the main heat generating ring and the auxiliary heat conducting ring are fixedly connected to a main magnetic sheet at one end close to the magnetic adjustment plate, and the main heat generating ring and the auxiliary heat conducting ring are fixedly connected to an auxiliary magnetic sheet at one end away from the magnetic adjustment plate. The magnetic properties of the main magnetic sheet and the auxiliary magnetic sheet are opposite. Therefore, there is a mutual repulsive force between an adjacent pair of heat generating rings due to the proximity of the main magnetic sheet and the auxiliary magnetic sheet. In the absence of external forces, the multiple heat generating rings will maintain the same spacing to achieve a state of equilibrium. Moreover, when the position of one of the heat generating rings moves, the magnetic force between them changes, breaking the balance of the forces between them, so that the heat generating rings on both adjacent sides move under the action of the magnetic force, thereby realizing a friction movement of one to many, which is convenient for generating a large amount of heat energy.

[0011] Furthermore, the magnetic adjustment plate includes a rotating plate fixedly connected to the extension rod, and the side wall of the rotating plate is fixedly connected with multiple main magnetic blocks and multiple auxiliary magnetic blocks, the main magnetic blocks and the auxiliary magnetic blocks are evenly distributed at intervals, the rotating plate and the main magnetic blocks also have opposite magnetism, and there are opposite magnetic forces between the rotating plate, the main magnetic blocks and the main magnetic sheet (that is, one of the rotating plate and the main magnetic block is attracted to the main magnetic sheet, and the other is repelled from the main magnetic sheet). When the rotating plate rotates, the rotating plate and the main magnetic block will cyclically and regularly face the main magnetic sheets on the adjacent two sides, and continuously and cyclically exert an attraction and repulsion force on the main magnetic sheet, so that a pair of heat generating rings close to the magnetic adjustment plate continuously move back and forth. At the same time, because there is also a repulsive force between adjacent heat generating rings, one heat generating ring will drive other heat generating rings to move at the same time, so that the rotation of the magnetic adjustment plate realizes the simultaneous movement of multiple heat generating rings, and a large amount of heat energy is generated by the continuous friction between the heat generating ring and the first friction ring and the second friction ring of the inner wall of the inner cavity, so that the temperature rise of the heat transfer fluid plays a role in heat preservation and antifreeze for the oil pipeline.

[0012] Furthermore, a plurality of pairs of partitions are fixedly connected between the main heat-generating ring and the auxiliary heat-conducting ring, and the partitions are fixedly connected between a pair of fixed nets. A plurality of friction balls are placed between the pair of partitions. When the heat-generating ring moves under the action of the magnetic force, the friction balls will also move back and forth. During the movement, the plurality of friction balls will collide and rub against each other and generate heat, thereby achieving frictional heat generation inside the heat-generating ring itself, and also providing heat for the temperature rise of the heat-conducting liquid, further improving the antifreeze effect of the device.

[0013] Furthermore, a liquid inlet pipe is provided on the upper side of the magnetic tuning plate, the upper end of the liquid inlet pipe is fixedly connected to the inner wall of the inner cavity, and the lower end of the liquid inlet pipe is in contact with the upper end of the magnetic tuning plate. The liquid inlet pipe plays a limiting role on the magnetic tuning plate, so that the magnetic tuning plate can achieve stable rotation, and also ensures the stable rotation of the extension rod and the vertical axis windmill.

[0014] Furthermore, the outer end of the antifreeze pipe is fixedly connected with an anti-overflow sleeve, and the anti-overflow sleeve is located on the outside of the vertical shaft. The anti-overflow sleeve includes an outer cylinder, and the inner surface of the outer cylinder is fixedly connected with absorbent cotton. The absorbent cotton can absorb the heat transfer liquid overflowing from the connection between the extension rod and the antifreeze pipe, so that the heat transfer liquid is not easy to flow out.

[0015] Furthermore, the upper and lower ends of the antifreeze pipe are respectively fixedly connected with a liquid inlet pipe and a liquid outlet pipe, and the liquid inlet pipe and the liquid outlet pipe are both communicated with the inner cavity. The outer ends of the liquid inlet pipe and the liquid outlet pipe are threadedly connected with pipe covers. The liquid inlet pipe is used to add heat transfer liquid into the inner cavity, and the liquid outlet pipe is used to discharge the heat transfer liquid.

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] (1) This scheme uses external wind energy to drive the vertical axis windmill and the magnetic adjustment plate to rotate. Through the continuous rotation of the magnetic adjustment plate, the magnetic force between the magnetic adjustment plate and the heat generating ring changes repeatedly, so that a pair of heat generating rings close to the magnetic adjustment plate continuously move back and forth. At the same time, because there is an equal magnetic force between adjacent heat generating rings, the movement of one heat generating ring breaks the magnetic force balance between the heat generating rings, so that the other heat generating rings move under the change of magnetic force, realizing the friction movement of one to many. A large amount of heat energy is generated by the continuous friction between the first friction ring and the second friction ring and the heat generating ring. In addition, the heat generating ring also generates friction heat inside itself during the movement process. The two forms of friction heat are used to heat the heat transfer fluid through heat to increase its temperature, thereby realizing the continuous spontaneous insulation and antifreeze effect on the oil pipeline.

[0019] (2) The heat generating ring includes a main heat conducting ring and a secondary heat conducting ring. The main heat conducting ring is located on the outside of the secondary heat conducting ring. A pair of fixed nets are fixedly connected between the main heat conducting ring and the secondary heat conducting ring. The main heat conducting ring is fixedly connected to the outer surface of the first friction ring near the main heat conducting ring. The secondary heat conducting ring is fixedly connected to the inner surface of the second friction ring near the secondary heat conducting ring. When the heat generating ring slides back and forth inside the inner cavity, the third friction ring will rub back and forth with the first friction ring, and the fourth friction ring will rub back and forth with the second friction ring. The mechanical energy is converted into heat energy generated during the friction process. The heat energy is then absorbed by the heat conducting fluid in the inner cavity, so that the temperature of the heat conducting fluid increases, thereby playing a role in heat preservation and antifreeze for the oil pipeline inside the antifreeze pipe.

[0020] (3) The main heat generating ring and the auxiliary heat conducting ring are fixedly connected to the main magnetic sheet at one end close to the magnetic adjustment plate, and the main heat generating ring and the auxiliary heat conducting ring are fixedly connected to the auxiliary magnetic sheet at one end away from the magnetic adjustment plate. The magnetic properties of the main magnetic sheet and the auxiliary magnetic sheet are opposite. Therefore, there is a mutual repulsion force between an adjacent pair of heat generating rings due to the proximity of the main magnetic sheet and the auxiliary magnetic sheet. In the absence of external forces, the multiple heat generating rings will maintain the same spacing to achieve a state of equilibrium. Moreover, when the position of one of the heat generating rings moves, the magnetic force between them changes, breaking the balance of the force between them, so that the heat generating rings on both sides move under the action of the magnetic force, thereby realizing a friction movement of one to many, which is convenient for generating a large amount of heat energy.

[0021] (4) The magnetic adjustment plate includes a rotating plate fixedly connected to the extension rod, and a plurality of main magnetic blocks and a plurality of auxiliary magnetic blocks are fixedly connected to the side wall of the rotating plate. The main magnetic blocks and the auxiliary magnetic blocks are evenly distributed at intervals. The rotating plate and the main magnetic blocks also have opposite magnetism, and there are also opposite magnetic forces between the rotating plate and the main magnetic blocks and the main magnetic sheet (that is, one of the rotating plate and the main magnetic block attracts the main magnetic sheet, and the other repels the main magnetic sheet). When the rotating plate rotates, the rotating plate and the main magnetic block will cyclically and regularly face the main magnetic sheets on the adjacent two sides, and continuously and cyclically exert an attraction and repulsion force on the main magnetic sheet, so that a pair of heat generating rings close to the magnetic adjustment plate continuously move back and forth. At the same time, due to the repulsion force between adjacent heat generating rings, one heat generating ring will drive other heat generating rings to move simultaneously, so that the rotation of the magnetic adjustment plate realizes the simultaneous movement of multiple heat generating rings, and a large amount of heat energy is generated by the continuous back and forth friction between the heat generating ring and the first friction ring and the second friction ring of the inner wall of the inner cavity, so that the temperature rise of the heat transfer fluid plays a role in heat preservation and antifreeze of the oil pipeline.

[0022] (5) A plurality of pairs of partitions are fixedly connected between the main heat generating ring and the auxiliary heat conducting ring. The partitions are fixedly connected between a pair of fixed nets. A plurality of friction balls are placed between the pair of partitions. When the heat generating ring moves under the action of the magnetic force, the friction balls will also move back and forth. During the movement, the plurality of friction balls will collide and rub against each other and generate heat, thereby realizing frictional heat generation inside the heat generating ring itself, and also providing heat for the temperature rise of the heat conducting fluid, further improving the antifreeze effect of the device.

[0023] (6) A liquid inlet pipe is provided on the upper side of the magnetic adjustment plate, the upper end of the liquid inlet pipe is fixedly connected to the inner wall of the inner cavity, and the lower end of the liquid inlet pipe is in contact with the upper end of the magnetic adjustment plate. The liquid inlet pipe acts as a limiter on the magnetic adjustment plate, so that the magnetic adjustment plate can achieve stable rotation, and also ensures the stable rotation of the extension rod and the vertical axis windmill.

[0024] (7) The outer end of the antifreeze pipe is fixedly connected with an anti-overflow sleeve, which is located on the outer side of the vertical shaft. The anti-overflow sleeve includes an outer cylinder, and the inner surface of the outer cylinder is fixedly connected with absorbent cotton. The absorbent cotton can absorb the thermal liquid overflowing from the connection between the extension rod and the antifreeze pipe, so that the thermal liquid is not easy to flow out.

[0025] (8) The upper and lower ends of the antifreeze pipe are respectively fixedly connected with a liquid inlet pipe and a liquid outlet pipe, the liquid inlet pipe and the liquid outlet pipe are both communicated with the inner cavity, and the outer ends of the liquid inlet pipe and the liquid outlet pipe are threadedly connected with pipe covers. The liquid inlet pipe is used to add heat transfer liquid into the inner cavity, and the liquid outlet pipe is used to discharge the heat transfer liquid. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the magnetic adjustment plate 4 is fixedly connected with an extension rod 9, which passes through the upper end of the antifreeze pipe 1 and is rotatably connected to the inside of the antifreeze pipe 1. Please refer to Figure 8 and Fig. 9 The vertical axis windmill 2 includes a vertical axis 21, the lower end of the vertical axis 21 is sleeved on the outside of the extension rod 9, and a bolt assembly 10 is connected between the vertical axis 21 and the extension rod 9. The bolt assembly 10 includes a bolt and a nut. Screw holes are opened on the vertical axis 21 and the extension rod 9, and the bolts are threadedly connected to the inside of the screw holes.

[0043] See also Figure 2 and Figure 5 , a plurality of heat generating rings 3 are arranged inside the inner cavity 101, and the plurality of heat generating rings 3 are evenly distributed on the left and right sides of the magnetic adjustment plate 4, please refer to Figure 3 , Figure 5 and Figure 6 The inner wall of the inner cavity 101 away from the oil pipeline is fixedly connected with the first friction ring 5, and the inner wall of the inner cavity 101 close to the oil pipeline is fixedly connected with the second friction ring 6. The heat generating ring 3 includes a main heat conducting ring 31 and a secondary heat conducting ring 32. The main heat conducting ring 31 is located on the outside of the secondary heat conducting ring 32. A pair of fixed nets 37 are fixedly connected between the main heat conducting ring 31 and the secondary heat conducting ring 32.

The heat energy is then absorbed by the heat conducting fluid in the inner cavity 101, so that the heat conducting fluid The temperature rises, thereby playing a role in heat preservation and antifreeze for the oil pipeline inside the antifreeze pipe 1.

The magnetic properties of the main magnetic piece 35 and the auxiliary magnetic piece 36 are opposite. Therefore, there is a mutual repulsive force between an adjacent pair of heat generating rings 3 due to the proximity of the main magnetic piece 35 and the auxiliary magnetic piece 36. In the absence of external force, multiple heat generating rings 3 will maintain the same spacing to achieve a state of equilibrium, and when the position of one of the heat generating rings 3 moves, the magnetic force between them changes, which breaks the balance of the force between them, so that the heat generating rings 3 on both sides of the adjacent sides move under the action of the magnetic force, thereby realizing a friction movement of one to many, which is convenient for generating a large amount of heat energy.

[0044] See also Fig. 9 and Fig.10The magnetic adjustment plate 4 includes a rotating plate 41 fixedly connected to the extension rod 9, and a plurality of main magnetic blocks 42 and a plurality of auxiliary magnetic blocks 43 are fixedly connected to the side wall of the rotating plate 41. The main magnetic blocks 42 and the auxiliary magnetic blocks 43 are evenly spaced. The rotating plate 41 and the main magnetic blocks 42 also have opposite magnetic properties, and there are also opposite magnetic forces between the rotating plate 41 and the main magnetic blocks 42 and the main magnetic sheet 35 (that is, one of the rotating plate 41 and the main magnetic block 42 is attracted to the main magnetic sheet 35, and the other is repelled from the main magnetic sheet 35). When the rotating plate 41 rotates, the rotating plate 41 and the main magnetic block 42 will cycle and repetitively and regularly with the adjacent The main magnetic sheets 35 on both sides are opposite to each other, and continuously and cyclically exert an attraction and repulsion force on the main magnetic sheets 35, so that a pair of heat generating rings 3 close to the magnetic adjustment plate 4 continuously move back and forth. At the same time, due to the repulsion force between adjacent heat generating rings 3, one heat generating ring 3 will drive other heat generating rings 3 to move simultaneously, so that the rotation of the magnetic adjustment plate 4 realizes the simultaneous movement of multiple heat generating rings 3, and a large amount of heat energy is generated by the continuous back and forth friction between the heat generating ring 3 and the first friction ring 5 and the second friction ring 6 of the inner wall of the inner cavity 101, so that the temperature rise of the heat transfer fluid plays a role in heat preservation and antifreeze for the oil pipeline.

The partitions 39 are fixedly connected between a pair of fixed nets 37. A plurality of friction balls 38 are placed between the pair of partitions 39. When the heat generating ring 3 moves under the action of magnetic force, the friction balls 38 will also move back and forth. During the movement, the plurality of friction balls 38 will collide and rub against each other and generate heat, thereby realizing frictional heat generation inside the heat generating ring 3 itself, and also providing heat for the temperature rise of the heat conducting liquid, further improving the antifreeze effect of the device.

[0046] See also Figure 4 A pair of side walls of the inner cavity 101 are fixedly connected with side magnetic sheets 7, and there is also a repulsive force between the side magnetic sheets 7 and the auxiliary magnetic sheets 36, so that the heat generating rings 3 located at the head and tail sides of the inner cavity 101 are not easy to approach and collide with the side walls of the inner cavity 101.

The liquid inlet pipe 11 limits the magnetic adjustment plate 4, so that the magnetic adjustment plate 4 can achieve stable rotation, and also ensures the stable rotation of the extension rod 9 and the vertical axis windmill 2.

The liquid inlet pipe 11 is used to add heat transfer liquid into the inner cavity 101, and the liquid outlet pipe 12 is used to discharge the heat transfer liquid. A liquid that is easy to conduct heat, has low viscosity and high fluidity (such as water) can be used as the heat transfer liquid, which is convenient for absorbing and transferring heat while not easily hindering the movement of internal objects.

[0049] The present invention utilizes external wind energy to drive the vertical axis windmill 2 and the magnetic adjustment plate 4 to rotate. Through the continuous rotation of the magnetic adjustment plate 4, the magnetic force between the magnetic adjustment plate 4 and the heat generating ring 3 changes repeatedly, so that a pair of heat generating rings 3 close to the magnetic adjustment plate 4 continuously move back and forth. At the same time, because there is an equal magnetic force between adjacent heat generating rings 3, the movement of one heat generating ring 3 breaks the magnetic force balance between the heat generating rings 3, so that the other heat generating rings 3 move under the change of magnetic force, realizing the friction movement of one to bring many. A large amount of heat energy is generated by the continuous friction between the first friction ring 5 and the second friction ring 6 and the heat generating ring 3. In addition, the heat generating ring 3 also generates friction heat inside itself during the movement process.
