Abstract
Description
Technical Field
[0001] This utility model relates to the field of natural gas pipeline technology, and in particular to a pipeline anti-water accumulation device. Background Technology
[0002] Currently, long-distance pipeline systems are commonly used to transport natural gas from production sites to distant consumer markets. These systems typically span hundreds or even thousands of kilometers. These systems are characterized by large diameters and high pressures, enabling efficient and continuous transport of large quantities of natural gas. However, natural gas carries a certain amount of water vapor during extraction. This water vapor can condense during transport due to external environmental factors (such as temperature changes). This condensation can form water accumulation on the inner side of the pipeline, potentially causing corrosion and shortening its lifespan. It also poses a risk of natural gas leaks.
[0003] In existing technologies, water is usually extracted from the inside of natural gas pipelines. However, this method of removing water from pipelines carries the risk of natural gas leakage during operation, and the water inside the pipeline cannot be completely removed, or it will remain damp.

The wedge-shaped component has a first contact surface, which is inclined in a first direction; the first direction is the extension direction of the target pipe. The contact ring is fitted onto both the target pipe and the heating component and is movable along the first direction. The movement of the contact ring along the first direction allows it to abut against the first contact surface, thereby driving the heating component to move along a second direction; the second direction forms an angle with the first direction.

[0008] In some embodiments, there are multiple abutment rings, which are spaced apart along the first direction; there are multiple wedges, which are spaced apart along the first direction; the multiple abutment rings and the multiple wedges are arranged in a one-to-one correspondence, and each abutment ring can abut against the first abutment surface of the corresponding wedge when it moves along the first direction.
[0009] In some embodiments, the pipe anti-water accumulation device further includes: a first housing, sleeved on the target pipe, wherein the heating component, the wedge, and the abutment ring are all located between the inner sidewall of the first housing and the outer sidewall of the target pipe.
[0010] In some embodiments, the pipe anti-water accumulation device further includes: a reset component, one end of which is connected to the inner wall of the first housing, and the other end of which is connected to the side of the heating component away from the target pipe; the reset component is always able to pull the heating component in the second direction to move the heating component away from the target pipe.
[0011] In some embodiments, the reset assembly includes: a fixed base, one end of which is connected to the inner wall of the first housing; the fixed base has a sliding cavity along the second direction; a limiting portion is provided at the opening of the sliding cavity; a pull rod, including a connecting portion and a sliding portion; the connecting portion is connected to the side of the heating assembly opposite to the target pipe, and the sliding portion is slidably disposed in the sliding cavity; an elastic member, sleeved on the connecting portion and located in the sliding cavity; in the second direction, the elastic member is located between the sliding portion and the limiting portion.
[0012] In some embodiments, the pipe anti-water accumulation device further includes: a first driving component disposed on the inner side wall of the first housing and throttle connected to the abutment ring; the first driving component is capable of driving the abutment ring to move along the first direction.
[0013] In some embodiments, the first drive assembly includes: a first motor disposed on the inner sidewall of the first housing; and a transmission threaded rod, one end of which is connected to the output shaft of the first motor, and the other end of which is threadedly connected to the abutment ring.

[0016] The beneficial effects of this utility model are:
[0017] This invention provides a pipe anti-water accumulation device. It involves installing a heating component on the outside of the target pipe, and a wedge-shaped component connected to the heating component and located on the side of the heating component away from the target pipe. A first abutment surface inclined in a first direction is provided on the wedge-shaped component, and an abutment ring is simultaneously fitted onto the target pipe and the heating component, and is movable along the first direction. When the abutment ring moves along the first direction, it abuts against the first abutment surface on the wedge-shaped component. Because the first abutment surface is inclined in the first direction, as the abutment ring gradually moves in the first direction, the contact between the abutment ring and the first abutment surface generates a decomposition of normal force (perpendicular to the contact surface) and tangential force (parallel to the contact surface). Through the inclined plane geometry, the horizontal movement is converted into vertical displacement; that is, the movement of the abutment ring along the first direction is converted into displacement of the wedge-shaped component in a second direction. Furthermore, when the wedge-shaped component displaces in the second direction, it can drive the connected heating component to displace in the second direction. In other words, when the abutment ring moves along the first direction, it can drive the heating component to move closer to the target pipe. This reduces the distance between the heating element and the target pipe in the first direction. The heating element then heats the interior of the pipe by releasing heat. As the temperature inside the pipe rises, the water inside evaporates more quickly, gradually eliminating the water. This process of eliminating water from the pipe does not require drilling or inserting anything into it, improving safety. Furthermore, this method avoids leaving the pipe damp even when it is dry, enhancing the effectiveness of water removal and extending the pipe's lifespan. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] Combination Figures 1 to 7 As shown, this embodiment provides a pipeline anti-water accumulation device to prevent water accumulation inside a target pipeline 1. The target pipeline 1 is, for example, a natural gas pipeline. Figure 1 As shown, the pipe anti-water accumulation device includes: heating component 2, wedge 3 and abutment ring 4.
[0033] like Figure 1As shown, the heating component 2 is disposed on the outside of the target pipe 1. The function of the heating component 2 is to heat the target pipe 1, thereby increasing the internal temperature of the target pipe 1. For example, the heating component 2 can be an infrared radiation heating plate, which is a plate-shaped carbon fiber infrared heating element that can penetrate the pipe wall of the target pipe 1 through infrared radiation to heat the air inside the target pipe 1; the heating component 2 can also be a ceramic heating plate (PTC heating plate), which includes a strip-shaped or rectangular ceramic substrate, a built-in PTC (positive temperature coefficient) heating element, and a metal heat-conducting plate covering the surface; the heating component 2 can also be an aluminum alloy heating strip, which includes an aluminum alloy strip-shaped outer shell, with an electric heating tube or heating wire embedded inside the outer shell, achieving the heating function through the electric heating tube or heating wire. Those skilled in the art can flexibly select and configure according to actual usage needs, and no further limitations are made here.
[0034] like Figure 1 As shown, the wedge-shaped member 3 is connected to the heating assembly 2, which may be a fixed connection or a detachable connection. The wedge-shaped member 3 is located on the side of the heating assembly 2 away from the target pipe 1, that is, also Figure 1 Taking the perspective shown as an example, the heating component 2 is located on the lower side of the target pipe 1, and the wedge-shaped part 3 is connected to the lower surface of the heating component 2.
[0035] Combination Figure 5 , Figure 6 As shown, the aforementioned abutment ring 4 has a circular structure, and the inner diameter of the abutment ring 4 should be larger than the outer diameter of the aforementioned target pipe 1. The abutment ring 4 can be simultaneously fitted onto the aforementioned target pipe 1 and the heating assembly 2, and the abutment ring 4 can move along a first direction X1, where the first direction X1 is the extension direction of the aforementioned target pipe 1.
[0036] like Figure 1 As shown, the wedge-shaped member 3 is provided with a first abutting surface 31, which is inclined in the first direction X1. The abutting ring 4 can move along the first direction X1 to abut against the first abutting surface 31 of the wedge-shaped member 3, thereby driving the heating component 2 to move along the second direction X2. Here, the second direction X2 is set at an angle to the first direction X1, for example, 90°.
[0037] It is easy to understand that, in order to make the abutting ring 4 and the wedge 3 abut together more smoothly, a second abutting surface can be provided on the side of the abutting ring 4 near the wedge 3. The second abutting surface has the same inclination direction as the first abutting surface 31 mentioned above. The abutting ring 4 can abut with the first abutting surface 31 on the wedge 3 through the second abutting surface.
[0038] Therefore, the pipe anti-water accumulation device provided in this embodiment is provided by setting a heating component 2 on the outside of the target pipe 1, setting a wedge-shaped member 3 connected to the heating component 2 and located on the side of the heating component 2 away from the target pipe 1; and setting a first abutting surface 31 inclined in the first direction X1 on the wedge-shaped member 3, and setting an abutting ring 4 that is simultaneously sleeved on the target pipe 1 and the heating component 2 and can move along the first direction X1. When the abutting ring 4 moves along the first direction X1, it abuts against the first abutting surface 31 on the wedge 3. Since the first abutting surface 31 is inclined in the first direction X1, as the abutting ring 4 gradually moves in the first direction X1, the contact between the abutting ring 4 and the first abutting surface 31 generates a decomposition of normal force (perpendicular to the contact surface) and tangential force (parallel to the contact surface). Through the inclined plane geometry, the horizontal movement is converted into vertical displacement. That is, the movement of the abutting ring 4 along the first direction X1 is converted into the displacement of the wedge 3 in the second direction X2. Furthermore, when the wedge 3 is displaced in the second direction X2, it can drive the heating component 2 connected to it to be displaced in the second direction X2. In other words, when the abutting ring 4 moves along the first direction X1, it can drive the heating component 2 to move towards the target pipe 1. This reduces the distance between the heating element 2 and the target pipe 1 in the first direction X1. The heating element 2 can then heat the internal space of the target pipe 1 through its own heat release. As the temperature inside the target pipe 1 rises, the water inside will evaporate more quickly, gradually eliminating the water. In this process of eliminating water inside the target pipe 1, there is no need to open holes in the pipe or insert anything inside, improving safety. Furthermore, this method avoids the pipe being in a damp state even without water accumulation, improving the effectiveness of water removal and thus extending the service life of the target pipe 1.
[0039] For example, such as Figure 1 As shown, the wedge-shaped member 3 includes a first end 32 and a second end 33. In the second direction X2, the size of the first end 32 of the wedge-shaped member 3 is smaller than the size of the second end 33 of the wedge-shaped member 3. The first abutment surface 31 extends from the first end 32 to the second end 33. In other words, with Figure 2Taking the shown perspective as an example, the left end of the wedge-shaped member 3 is the first end 32, and the right end is the second end 33. The cross-sectional area of the left end of the wedge-shaped member 3 is smaller than that of the other end, or in other words, the cross-sectional area of the wedge-shaped member 3 gradually increases from left to right (the aforementioned cross-sectional directions are all perpendicular to the first direction X1). The first abutting surface 31 extends obliquely from the left end of the wedge-shaped member 3 to the right end of the wedge-shaped member 3, or in other words, the first abutting surface 31 is an oblique surface, and its oblique direction is from the upper left to the lower right. In the first direction X1, the aforementioned abutting ring 4 is disposed on the side of the first end 32 away from the second end 33. When the aforementioned abutment ring 4 moves along the first direction X1 (i.e., from left to right), the abutment ring 4 first abuts against the left end (first end 32) of the wedge 3 and simultaneously against the first abutment surface 31. As the abutment ring 4 moves further to the right, due to the structural characteristics of the wedge 3 (i.e., the left end is smaller and the right end is larger), the first abutment surface 31 will apply a downward force F1 to the abutment ring 4, and the abutment ring 4 will apply an upward force F2 to the first abutment surface 31. However, since the abutment ring 4 is fitted onto the target pipe 1, the abutment ring 4 cannot move downward. Thus, under the action of the force F2 applied to the first abutment surface 31, the wedge 3 will move upward, thereby driving the heating component 2 connected to the wedge 3 to move upward, that is, to move towards the target pipe 1. With the above configuration, the abutting ring 4 can move along the first direction X1 and abut against the first abutting surface 31 of the wedge 3, thereby driving the heating component 2 to move along the second direction X2. The structure is simple, easy to process and manufacture, and easy to use.
[0040] In some embodiments, combined with Figure 1 , Figure 5 , Figure 6 As shown, there are multiple abutment rings 4, which are spaced apart along the first direction X1. There are also multiple wedge-shaped members 3, which are spaced apart along the first direction X1. Each abutment ring 4 corresponds to one wedge-shaped member 3, and each abutment ring 4, when moved along the first direction X1, can abut against the first abutment surface 31 of the corresponding wedge-shaped member 3.
[0041] Here, the number of abutment rings 4 is, for example, two, and the number of wedge-shaped pieces 3 is also, for example, two, with the two abutment rings 4 corresponding to the two wedge-shaped pieces 3 respectively. Figure 3Taking the shown perspective as an example, two abutment rings 4 are respectively fitted onto the left and right ends of the heating assembly 2. One wedge-shaped piece 3 is positioned to the right of the abutment ring 4 at the left end of the heating assembly 2, and the other wedge-shaped piece 3 is positioned to the left of the abutment ring 4 at the right end of the heating assembly 2. When the abutment ring 4 at the left end of the heating assembly 2 moves to the right along the first direction X1, it abuts against the first abutment surface 31 on the corresponding wedge-shaped piece 3; when the abutment ring 4 at the right end of the heating assembly 2 moves to the left along the first direction X1, it also abuts against the first abutment surface 31 on the corresponding wedge-shaped piece 3.
[0042] With the above configuration, the heating component 2 can be moved in the second direction X2 by abutting the first abutting surface 31 on the multiple abutting rings 4 against the multiple wedges 3. This makes the movement of the heating component 2 more stable and smooth, and the movement process is also more labor-saving.
[0043] In some embodiments, combined with Figure 3 , Figure 4 , Figure 5 As shown, the aforementioned pipe anti-water accumulation device also includes a first housing 5. This first housing 5 is, for example, a cylindrical housing. The first housing 5 is fitted onto the target pipe 1, and the heating component 2, wedge-shaped member 3, and abutment ring 4 are all located between the inner wall of the first housing 5 and the outer wall of the target pipe 1. By providing the first housing 5 and positioning the heating component 2, wedge-shaped member 3, and abutment ring 4 between the inner wall of the first housing 5 and the outer wall of the target pipe 1, the first housing 5 can protect these components. Simultaneously, it can also provide a certain degree of heat insulation, preventing excessive heat loss when the heating component 2 heats the target pipe 1, thus avoiding impact on heating efficiency.
[0044] In some embodiments, the aforementioned pipe waterproofing device further includes a reset component 6. One end of the reset component 6 is connected to the inner wall of the first housing 5, and the other end is connected to the side of the heating component 2 away from the target pipe 1. The reset component 6 can be directly connected to the inner wall of the first housing 5, or indirectly connected to the inner wall of the first housing 5 via other components (e.g., a connecting plate). The reset component 6 is always able to pull the heating component 2 away from the target pipe 1 in the second direction X2. This arrangement ensures that after the heating component 2 removes the water accumulation inside the target pipe 1 through heating, the reset component 6 resets the heating component 2, moving it away from the target pipe 1, thus preventing the heating component 2 from heating the target pipe 1 for an extended period and avoiding potential safety hazards.
[0045] In some embodiments, such as Figure 7As shown, the reset assembly 6 includes a fixed base 61, a pull rod 62, and an elastic element 63. One end of the fixed base 61 is connected to the inner wall of the first housing 5. The fixed base 61 has a sliding cavity 611 along the second direction X2, and a limiting part 612 is provided at the opening of the sliding cavity 611. The pull rod 62 includes a connecting part 621 and a sliding part 622. The connecting part 621 of the pull rod 62 is connected to the side of the heating assembly 2 away from the target pipe 1, and the sliding part 622 of the pull rod 62 is slidably disposed within the sliding cavity 611 of the fixed base 61. The elastic element 63 is, for example, a compression spring. The elastic element 63 is sleeved on the connecting part 621 of the pull rod 62 and located within the sliding cavity 611 of the fixed base 61. In the second direction X2, the elastic element 63 is located between the sliding part 622 and the limiting part 612, and is used to store or release elastic potential energy to achieve the reset of the heating assembly 2. When the heating component 2 moves upward under the action of the abutment ring 4 (moving towards the target pipe 1), the connecting part 621 of the pull rod 62 connected to it moves upward synchronously, and at the same time, the sliding part 622 of the pull rod 62 moves upward synchronously within the sliding cavity 611 of the fixed seat 61. As the sliding part 622 moves upward, it compresses the elastic member 63 located between the sliding part 622 and the limiting part 612 of the fixed seat 61. The compression of the elastic member 63 converts the kinetic energy applied by the sliding part 622 into its own elastic potential energy. When the abutment ring 4 no longer abuts against the wedge 3, the heating component 2 is no longer subjected to an upward force. At this time, the elastic member 63 returns to its normal state from the compressed state, and the elastic potential energy of the elastic member 63 is converted into kinetic energy. The elastic member 63 pushes the sliding part 622 downward. Thus, the sliding part 622 drives the connecting part 621, and in turn, drives the heating component 2 downward (moving away from the target pipe 1), thereby realizing the reset of the heating component 2. The structure is simple, easy to use, and easy to manufacture.
[0046] In some embodiments, such as Figure 6 As shown, the aforementioned pipe water accumulation device also includes a first driving component 7. This first driving component 7 is disposed on the inner side wall of the first housing 5 and is pulsatorically connected to the abutment ring 4. The first driving component 7 can drive the abutment ring 4 to move along the first direction X1. With this configuration, the abutment ring 4 can be moved using the first driving component, making operation convenient and saving manpower.
[0047] For example, such as Figure 6As shown, the first drive assembly 7 includes a first motor 71 and a transmission threaded rod 72. The first motor 71 is disposed on the inner wall of the first housing 5. The first motor 71 is connected to the inner wall of the first housing 5 via a fixing member 73, which is connected to the inner wall of the first housing 5, for example, by welding. One end of the transmission threaded rod 72 is connected to the output shaft of the first motor 71, and the other end is threadedly connected to the abutment ring 4. The threaded connection is, for example, that a threaded hole is formed on the abutment ring 4 along a first direction X1, which is adapted to the transmission threaded rod 72. The transmission threaded rod 72 can be rotatably connected to the abutment ring 4 through the meshing of the threads. Simultaneously, the transmission threaded rod 72 can push or pull the abutment ring 4 through the meshing of the threads. This configuration enables the first motor 71 to drive the abutment ring 4 to move in the first direction X1. The structure is simple and easy to maintain.
[0048] In some embodiments, combined with Figure 3 , Figure 4 As shown, the aforementioned pipe water accumulation device also includes a second housing 8 and a second driving component. The second housing 8 is, for example, a cylindrical housing, and is fitted onto the first housing 5. The second driving component 9 is disposed on the outer wall of the second housing 8 and is connected to the first housing 5 in a driving manner. The second driving component 9 can drive the first housing 5 to rotate about an axis parallel to the first direction X1 (i.e., the axis of the first housing 5 itself). This arrangement allows the heating component 2, which is disposed inside the first housing 5 and indirectly connected to its inner wall, to rotate during rotation. This changes the position of the heating component 2 relative to the outside of the target pipe 1, enabling it to heat different locations within the target pipe 1, improving the efficiency of water removal from the target pipe 1, and preventing the heating component 2 from consistently heating the same location within the target pipe 1, thus avoiding potential safety hazards.
[0049] In some embodiments, combined with Figure 3 , Figure 4The first housing 5 has multiple transmission teeth 51 arranged on its outer side wall, circumferentially surrounding it. The second drive assembly 9 includes a second motor 91 and a transmission gear 92. The second motor 91 is located on the outer side wall of the second housing 8; the transmission gear 92 is located on the output shaft of the second motor 91 and meshes with the transmission teeth 51 arranged circumferentially around the first housing 5. With this arrangement, when the second motor 91 starts, its output shaft drives the transmission gear 92 to rotate. The transmission gear 92, in conjunction with the meshing action of the multiple transmission teeth 51 on the first housing 5, drives the second housing 8 to rotate around its own axis. This achieves the goal of the second motor 91 driving the first housing 5 to rotate around an axis parallel to the first direction X1. The structure is simple, easy to design and manufacture, and convenient to maintain and repair.
[0050] To protect the internal structure of the anti-water accumulation device for the pipeline and to facilitate the connection of target pipeline 1 with other pipelines, such as Figure 2 As shown, the pipe anti-water accumulation device can also be provided with two annular connectors 10 and two protective shells 101. The two protective shells 101 are respectively covered at both ends of the second shell 8. The two connectors 10 are respectively set at the end faces of both ends of the target pipe 1. One side of the connector 10 can be connected to the first shell 5 and the second shell 8, and the other side can be connected to other pipes. The connection method is, for example, by bolt connection.
[0051] In addition, to facilitate the control of the first drive assembly 7, the second drive assembly 9, and the heating assembly 2, such as Figure 2 As shown, a control module 20 can also be installed on the outside of the second housing 8. This control module 20 is coupled to the first drive assembly 7, the second drive assembly 9, and the heating assembly 2, respectively. This coupling includes electrical connection and signal connection. The control module 20 can control the operating parameters of the first drive assembly 7, the second drive assembly 9, and the heating assembly 2, enabling the pipe anti-water accumulation device to meet the usage requirements of different scenarios and improving the practicality of the pipe anti-water accumulation device.
