Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a paraffin removal device according to an embodiment of the present application. The paraffin removal device may include:
suspension part 100, weight body 200 and adaptor part 300.
The first end of the hanging portion 100 in the paraffin removal device is configured to: is connected with the traction rope. The first end of the weight body 200 of the paraffin removal device is pointed.
The adaptor 300 of the paraffin removal device can be located between the second end of the hanger 100 and the second end of the weight body 200.
Referring to fig. 2, fig. 2 is a partial enlarged view of the paraffin removal device shown in fig. 1 at a. The adapter 300 may include: first revolving unit 301 and second revolving unit 302. The first revolving unit 301 may be fixedly coupled to the second end of the suspension unit 100. The second rotator 302 may be fixedly coupled to the second end of the weight body 200. The first rotator 301 and the second rotator 302 may be movably connected to each other. The first revolving unit 301 and the second revolving unit 302 are rotatable relative to each other.
Optionally, the paraffin removal device may further include: wiper blade assembly 400. The first end of the wiper blade assembly 400 may be coupled to the first end of the hanger 100. The second end of the blade assembly 400 is configured to be coupled to a traction cable. In this case, the first end of the hanging part 100 is connected to the traction rope through the blade assembly 400.
In the embodiment of the application, as shown in fig. 3, fig. 3 is a schematic diagram of removing paraffin attached to the inner wall of an oil pipe by using the paraffin removal device shown in fig. 1. When it is desired to dewater the paraffin attached to the inner wall of the oil pipe 002 by using the paraffin removal device of the embodiment of the present application, first, an operator may connect the pull rope 001 to the second end of the wiper blade assembly 400.
The operator may then attach the first end of the wiper blade assembly 400 to the first end of the hanger 100.
After that, the paraffin removal device is placed in the oil pipe 002 to be dredged through the pulling rope.
Finally, the paraffin removal device moves in the oil pipe 002 under the action of gravity of the heavy hammer body 200, so as to drive the wiper blade assembly 400 to move in the oil pipe 002, and the wiper blade assembly 400 can remove paraffin attached to the inner wall of the oil pipe 002, thereby achieving the purpose of dredging the oil pipe 002 to be dredged.
It should be noted that, since the adaptor 300 is disposed between the second end of the suspension unit 100 and the second end of the weight body 200, the adaptor 300 includes the first rotator 301 and the second rotator 302, and the first rotator 301 and the second rotator 302 can rotate relatively. And the second end of the suspension part 100 is fixedly connected to the first rotator 301, and the second end of the weight body 200 is fixedly connected to the second rotator 302. Therefore, when the weight body 200 rotates in the oil pipe 002, the weight body 200 can drive the second rotator 302 to rotate around the first rotator 301, and the first rotator 301 does not rotate relative to the oil pipe 002. Therefore, the suspension portion 100 fixedly connected to the first revolving body 301 does not rotate, so that the probability of winding the traction rope connected to the suspension portion 100 is reduced, the probability of blocking of the wiper blade assembly 400 in the oil pipe 002 is reduced, and the paraffin removal efficiency of the paraffin removal device is effectively improved.
In summary, the paraffin removal device provided in the embodiment of the present application includes: the weight comprises a hanging part, a weight body and a switching part between the second end of the hanging part and the second end of the weight body. The adapter includes a first rotator and a second rotator. If the paraffin removal device is used for removing paraffin attached to the inner wall of the oil pipe, when the heavy hammer body rotates in the oil pipe, the heavy hammer body can drive the second revolving body to rotate around the first revolving body, and the first revolving body does not rotate relative to the oil pipe. Therefore, the hanging part fixedly connected with the first revolving body does not rotate, the probability of winding phenomenon of the traction rope connected with the hanging part is reduced, the probability of blocking phenomenon of the scraping blade component in the oil pipe is reduced, and further the paraffin removal efficiency of the paraffin removal device is effectively improved.
In the embodiment of the present application, as shown in fig. 4 and 5, fig. 4 is a schematic structural diagram of another paraffin removal device according to the embodiment of the present application. Fig. 5 is a partial enlarged view of the paraffin removal device shown in fig. 4 at B. The adaptor 300 of the paraffin removal device may further include: a plurality of balls 303 are provided between the first rotator 301 and the second rotator 302 of the transfer portion 300. The plurality of balls 303 are slidably connected to the first rotator 301 of the adapter 300 and slidably connected to the second rotator 302 of the adapter 300. By way of example, the sphere 303 may be made of a metallic material. For example, the material of the sphere 303 is stainless steel, i.e., the sphere 303 is a steel ball.
In this case, first rotator 301 in adapter 300 can be slidably connected to second rotator 302 by a plurality of balls 303. Since the coefficient of friction between first rotator 301 and sphere 303 is small, and the coefficient of friction between second rotator 302 and sphere 303 is also small. Therefore, the resistance in relative rotation between first revolving unit 301 and second revolving unit 302 is small.
In this way, the resistance to relative rotation between the suspension 100 fixedly connected to the first rotator 301 and the weight body 200 fixedly connected to the second rotator 302 is small. The probability of the phenomenon that the traction rope connected with the hanging part 100 is wound is further reduced, and the probability of the phenomenon that the scraping blade assembly 400 is blocked in the oil pipe is further reduced, so that the paraffin removal efficiency of the paraffin removal device on paraffin in the oil pipe is further improved.
In an embodiment of the present application, as shown in fig. 4 and 5, the side wall of the second end of the hanging portion 100 in the paraffin removal device may have an annular protrusion 101 thereon. The first rotator 301 of the adapter 300 in the paraffin removal device may have a ring shape. The first revolving body 301 of the adapter part in the paraffin removal device is sleeved on the hanging part 100 in the paraffin removal device, and the first revolving body 301 of the adapter part 300 is fixedly connected with the annular protrusion 101 on the side wall of the second end of the hanging part 100 in the paraffin removal device.
For example, the first rotation body 301 of the adapter 300 may be fixedly connected to the annular protrusion 101 of the suspension portion 100 by welding or by screws. The embodiment of the present application is not limited thereto.
Optionally, the adaptor 300 of the paraffin removal device may further include: an end cap 304. The end cap 304 is fixedly connected to the second end of the weight body 200 of the paraffin removal device.
For example, the end cap 304 may be fixedly connected to the second end of the weight body 200 by welding, or may be fixedly connected by a screw. The embodiment of the present application is not limited thereto.
In the present application, the end cap 304 of the adapter 300 is also fixedly connected to the second rotator 302 of the adapter 300 of the paraffin removal device.
For example, the end cap 304 and the second rotator 302 of the adapter 300 may be fixedly connected by welding or by screws. The embodiment of the present application is not limited thereto.
In the embodiment of the present application, the end cover 304 of the adapter 300 and the second rotator 302 of the adapter 300 of the paraffin removal device may be annular, and the end cover 304 and the second rotator 302 of the adapter 300 of the paraffin removal device are sleeved on the suspension 100 of the paraffin removal device. The second rotator 302 in the adapter 300 is away from the annular protrusion 101 with respect to the first rotator 301.
In this case, since the second rotation body 302 in the adapter 300 is away from the annular projection 101 with respect to the first rotation body 301. The first revolving body 301 of the adapter 300 may be sleeved on the suspension portion 100, and the first revolving body 301 is fixedly connected with the annular protrusion 101 provided on the side wall of the second end of the suspension portion 100 in the paraffin removal device; the second rotator 302 of the adapter 300 may also be sleeved on the suspension portion 100, and the second rotator 302 is fixedly connected to the weight body 100 through the end cap 304. Therefore, the weight of the weight body 200 is small by the adaptor 300 between the second end of the hanging part 100 and the second end of the weight body 200, and the weight of the weight body 200 is mainly borne by the annular protrusion 101 provided on the sidewall of the second end of the hanging part 100 in the paraffin removal device. Therefore, the service life of the adaptor 300 can be effectively prolonged, and the problem that the adaptor 300 is damaged due to the fact that the adaptor 300 bears the weight of the heavy hammer body 200.
It should be noted that, there is a certain gap between the end cap 304 and the hanging portion 100 in the paraffin removal device. That is, the end cap 304 is a clearance fit with the hanger 100. Thus, when the paraffin removal device is positioned in the oil pipe and paraffin attached to the inner wall of the oil pipe is removed, if the weight body 200 in the paraffin removal device rotates, the weight body 200 can rotate around the hanging portion 100 through the switching portion 300 in the process of rotating around the hanging portion 100, and the end cover 304 in the switching portion 300 can be ensured to rotate freely around the hanging portion 100 through clearance fit between the end cover 304 in the switching portion 300 and the hanging portion 100.
In an embodiment of the present application, as shown in fig. 5, the second end of the weight body 200 of the paraffin removal device may have a groove 201, at least a portion of the end cap 304 of the adaptor 300 of the paraffin removal device is located in the groove 201, and at least a portion of the hanger 100 of the paraffin removal device is located in the groove 201.
In this case, when at least a portion of the end cap 304 of the adapter 300 of the paraffin removal device is located in the groove 201 on the second end of the weight body 200 of the paraffin removal device, at least a portion of the hanging portion 100 of the paraffin removal device is located in the groove 201 on the second end of the weight body 200 of the paraffin removal device, the overall structure of the paraffin removal device is compact, and the assembling process of the components of the paraffin removal device can be simplified.
Optionally, at least one spiral diversion trench 202 may be disposed on the sidewall of the weight body 200 in the paraffin removal device.
Under the circumstances, if this paraffin removal device is adopted to remove the paraffin that adheres to on the oil pipe inner wall, paraffin removal device removes in oil pipe under the effect of weight body 200 self in through paraffin removal device's gravity, through set up at least one heliciform guiding gutter 202 on the lateral wall of weight body 200 in paraffin removal device, can provide precession force for weight body 200 in paraffin removal device when the oil pipe is inside to accelerate weight body 200 and carry out rotatory speed in oil pipe, and then improved weight body 200 and carried out the speed of removing along the axial of oil pipe in oil pipe, further improved this paraffin removal device paraffin removal's effect.
In an embodiment of the present application, as shown in fig. 4, a first end of the hanging portion 100 is provided with a hanging ring 102. The suspension 100 may be coupled to the wiper blade assembly 400 via a bail 102.
By way of example, the wiper blade assembly 400 may include: a center rod 401, and a paraffin scraper 402 fixedly connected to a side wall of the center rod 401. The first end of the central rod 401 in the wiper assembly 400 has a first connecting eye 4011 that mates with the eye 102, and through the mating of the first connecting eye 4011 with the eye 102 on the hanger 100, a connection between the hanger 100 and the wiper assembly 400 can be achieved. For example, the first connecting eye 4011 may be connected to the eye 102 on the suspension 100 by a connecting rope.
In an embodiment of the present application, the second end of the center rod 401 in the wiper assembly 400 has a second connecting eye 4012. A second attachment eye 4012 on a second end of the wiper assembly 400 can be coupled to the pull cord 001 to suspend the paraffin removal unit.
In this case, when it is required to remove the paraffin attached to the inner wall of the oil pipe using the paraffin removal device of the embodiment of the present application, first, the operator can connect the pulling rope 001 to the second connection suspension 4012 on the second end of the center rod 401 in the wiper blade assembly; then, the operator may connect the first suspension ring 4011 on the first end of the center rod 401 with the suspension ring 102 on the first end of the suspension portion 100; then, placing the paraffin removal device in an oil pipe to be dredged through a traction rope 001; finally, the paraffin removal device moves in the oil pipe under the action of the gravity of the heavy hammer body 200, so that the paraffin scraping plate 402 in the scraping plate assembly 400 is driven to move in the oil pipe, and the paraffin scraping plate 402 can remove paraffin adhered on the inner wall of the oil pipe, so that the purpose of dredging the oil pipe to be dredged is achieved.
It should be noted that, the width of the paraffin scraper 402 in the radial direction of the oil pipe is slightly smaller than the inner diameter of the oil pipe (for example, less than 5 mm), so when the paraffin removal device is located in the oil pipe, the paraffin scraper 402 can effectively remove the paraffin attached to the inner wall of the oil pipe, and the paraffin removal efficiency of the paraffin removal device is improved.
Optionally, the material of the weight body 200 in the paraffin removal device may include metallic lead, etc.
It should be noted that, when the weight body 200 in the paraffin removal device is made of lead, the density of the metal lead is relatively high, and the weight of other metal parts with the same volume is relatively high, so that the weight body 200 can drive the paraffin removal device to remove paraffin in the oil pipe under the action of gravity, thereby effectively improving the paraffin removal efficiency of the paraffin removal device. In the embodiment of the present application, the material of the weight body 200 is not limited to metallic lead, but may be other metallic materials, which is not limited in the embodiment of the present application.
It should be noted that, when the material of the weight body 200 may be metallic lead, the weight body 200 is also commonly referred to as plumb.
Optionally, the first end of the weight body 200 in the paraffin removal device may be conical, and the range of the cone angle of the first end of the weight body 200 is: 25 degrees to 60 degrees.
For example, the taper angle of the first end of the weight body 200 can be set to 30 degrees in the embodiment of the present application. Under this condition, when the wiper blade assembly 400 is driven to move in the oil pipe under the action of gravity of the weight body 200, the conical first end of the weight body 200 can increase the moving speed of the wiper blade assembly 400, so that the wiper blade assembly 400 can be driven to move in the oil pipe more quickly, and the paraffin removal efficiency of the paraffin removal device is further improved.
In the present application, the hanging part 100 in the paraffin removal device may have a rod shape. For example, the hanging portion 100 may be a rod body having a cylindrical shape. The weight body 200 of the paraffin removal device may also have a cylindrical shape. In this case, after the hanger 100 is connected to the weight body 200 via the adaptor 300, the weight body 200 can be rotated relative to the hanger 100 via the adaptor 300.
The diameter of the cylindrical hanging portion 100 is exemplified by the range: 10 mm to 18 mm. For example, the diameter of the cylindrical hanging portion 100 may be 15 mm. The range of the height of the annular protrusion 101 provided on the second end of the hanging portion 100 is: 12 mm to 24 mm. For example, the height of the annular protrusion 101 may be 16 mm.
The length of the cylindrical weight body 200 ranges from: 1200 to 2000 mm. For example, the length of the cylindrical weight body may be 1600 mm. The diameter of the cylindrical weight body 200 ranges from: 30 mm to 50 mm. For example, the diameter of the cylindrical weight may be 42 millimeters.
In the present application, the width of the spiral diversion trench 202 in the weight body 200 in the paraffin removal device is in the range of: 3 mm to 8 mm. For example, the width of the channel 202 may be 5 millimeters. The depth range of the diversion trench is as follows: 3 mm to 8 mm. By way of example, the depth of the channel 202 may be 5 millimeters.
Referring to fig. 6 in combination with the above embodiment, fig. 6 is a schematic diagram of the paraffin removal device shown in fig. 4 for removing paraffin attached to the inner wall of the oil pipe. The following examples schematically illustrate the process of paraffin removal using the paraffin removal apparatus provided by the embodiments of the present application:
First, an operator can socket the adapter 300 on the suspension portion 100, socket the end cap 304 on the annular protrusion 101 of the suspension portion 100, and fixedly connect the end cap 304 with the second rotator 302 of the adapter 300.
Then, the second end of the hanging part 100 is placed into the groove 201 of the weight body 200, and the end cap 304 is fixedly connected to the second end of the weight body 200.
The operator may then attach the traction cable 001 to the second attachment eye 4012 at the second end of the central rod 401 in the blade assembly 400.
The operator may then connect the first connecting eye 4011 of the first end of the center rod 401 in the wiper assembly 400 with the eye 102 of the first end of the hanger 100.
Then, the paraffin removal device is placed in the oil pipe 002 to be dredged by the pulling rope 001.
Finally, the paraffin removal device moves in the oil pipe 002 to be dredged under the action of the gravity of the heavy hammer body 200, so as to drive the wiper blade assembly 400 to move in the oil pipe 002, and the wiper blade assembly 400 can remove paraffin attached to the inner wall of the oil pipe 002.
For example, in the process that the weight body 200 moves in the oil pipe 002 to be dredged by self gravity, the spiral diversion trench 202 arranged on the side wall of the weight body 200 provides a precession force when the weight body 200 moves in the oil pipe 002, so as to accelerate the rotation speed of the weight body 200 in the oil pipe 002. Moreover, the first end of the weight body 200 is a conical tip, and the conical tip can increase the moving speed of the weight body 200 in the oil pipe 002. In this way, the movement of the wiper blade assembly 400 in the oil pipe 002 can be quickened, and the paraffin removal efficiency of the paraffin removal device can be further improved.
When the weight body 200 rotates in the oil pipe 002, the first rotator 301 and the second rotator 302 of the adapter 300 can rotate relative to each other because the plurality of balls 303 are provided between the first rotator 301 and the second rotator 302. Therefore, when the weight body 200 rotates in the oil pipe 002, the weight body 200 can drive the second rotator 302 to rotate around the first rotator 301, and the first rotator 301 does not rotate relative to the oil pipe 002. In this way, the suspension portion 100 fixedly connected to the first revolving body 301 does not rotate, so that the probability of winding phenomenon of the traction rope connected to the suspension portion 100 is reduced, the probability of blocking phenomenon of the scraper assembly 400 in the oil pipe 002 is reduced, and further the paraffin removal efficiency of the paraffin removal device is effectively improved.
In summary, the paraffin removal device provided in the embodiment of the present application includes: the weight comprises a hanging part, a weight body and a switching part between the second end of the hanging part and the second end of the weight body. The adapter includes a first rotator and a second rotator. If the paraffin removal device is used for removing paraffin from the oil pipe, when the heavy hammer body rotates in the oil pipe, the heavy hammer body can drive the second revolving body to rotate around the first revolving body, and the first revolving body does not rotate relative to the oil pipe. Therefore, the hanging part fixedly connected with the first revolving body does not rotate, the probability of winding phenomenon of the traction rope connected with the hanging part is reduced, the probability of blocking phenomenon of the scraping blade component in the oil pipe is reduced, and further the paraffin removal efficiency of the paraffin removal device is effectively improved.
In the present disclosure, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.
In the present application, the description of the term "range" in the above embodiments shall include the end point values. For example, the term "range of 25 degrees to 60 degrees" includes the end point values of 25 degrees and the end point values of 60 degrees.
The foregoing description of the preferred embodiments of the present application is not intended to limit the application, but is intended to cover all modifications, equivalents, alternatives, and improvements falling within the spirit and principles of the application.
