Description

Technical Field

[0001] The utility model belongs to the technical field of crude oil processing and stabilization in ground engineering, and particularly relates to a closed oil unloading auxiliary device for a gathering and transportation station. Background Art

[0002] In oilfield gathering and transportation, crude oil produced by scattered wells on the edge of the field, as well as oil in storage tanks after recovery operations at operating well sites, all require oil trucks to be transported back to the unloading point for recovery. After the oil truck arrives at the unloading point, it must complete the static grounding work as required and then park at a fixed location for 15 minutes. A quick connector is then used to quickly connect the unloading port of the tank truck to the unloading pipe of the closed unloading device. The inlet valve of the closed unloading device is then smoothly opened, followed by the outlet valve of the tank truck, allowing the oil to enter the unloading pipe smoothly.

[0003] The oil unloading pipe is a key component in the entire oil unloading process. It is the key channel for oil and gas transportation, and its integrity is directly related to whether the oil and gas can smoothly enter the closed oil unloading buffer tank. The oil unloading pipe is mainly made of high-density polyethylene and lined with steel wire.

[0004] During oil unloading, contaminants in the oil can easily cause the unloading pump to drain. Connecting the oil pulling pipeline during unloading can easily cause the pipeline to bend. Furthermore, long-term outdoor operation of the pipeline can lead to pipeline aging and surface cracking. The weight of the oil and gas during unloading can cause the pipeline to bend, and the steel wire lining can break. This dual effect exacerbates damage to the unloading pipeline, leading to oil and gas leaks and pollution accidents. Broken steel wire linings in the unloading pipeline do not meet safety requirements, and static electricity cannot be effectively dissipated during the unloading process, which can easily lead to safety accidents.

[0005] A Chinese patent application, entitled "A Clean, Efficient, and Sealed Oil Unloading Device," with authorization publication number CN212174447U, discloses a clean, efficient, and sealed oil unloading device. The device comprises an oil storage tank, an oil unloading pipeline, a fixed assembly, a PLC controller, and a first alarm. The oil storage tank has a chamber within it, and an oil inlet connected to the chamber is provided on its sidewall. The top cover of the oil storage tank is made of a transparent material. One end of the oil unloading pipeline is sealedly connected to the oil unloading port, and the other end is sealedly connected to the oil inlet. The oil unloading pipeline is sequentially provided with an oil inlet valve, an online moisture analyzer, an on-off valve, and a filter. The fixed assembly includes a fixed frame and a recovery tank detachably mounted to the bottom of the fixed frame. The oil unloading pipeline is mounted on the fixed frame and located above the recovery tank. The PLC controller is connected to the online moisture analyzer, and the on-off valve and the first alarm are each connected to the PLC controller. This utility model improves oil unloading efficiency and avoids environmental pollution.

[0006] The disadvantages are that the on-site operation does not fundamentally solve the problem of the unloading oil pipe being bent and deformed, nor does it consider the problem of the remaining oil dripping from the pipeline after the unloading oil pipe unloads the oil, nor does it consider the problem of the unloading oil pipe being suspended. Utility Model Content

[0007] In order to solve the above problems in the prior art, that is, the unloading oil pipe is bent during the oil unloading process, and safety hazards such as personnel injury and oil and gas leakage are likely to occur, the present utility model provides a closed oil unloading auxiliary device for a gathering and transportation station yard.

Detailed implementation manners

[0045] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than limiting the utility model. Additionally, it should be noted that for the convenience of description, only the parts related to the relevant utility model are shown in the drawings.

[0046] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0047] The present utility model provides a closed oil unloading auxiliary device for gathering and transportation stations. Refer to Figure 1 , the closed oil unloading auxiliary device for gathering and transportation stations includes an oil unloading pipe 1, a support assembly 2 and a lifting assembly 3.

[0048] One end of the oil unloading pipe 1 is connected to the buffer tank, and the other end is used to be connected to the outlet of the oil truck. During the oil unloading process, the valve on the buffer tank is opened to make the oil unloading pipe 1 communicate with the inside of the buffer tank, and then the valve on the oil truck is opened to make the oil unloading pipe 1 communicate with the inside of the oil truck. The oil liquid contained in the oil truck flows into the oil unloading pipe 1 under the action of its own gravity, and then enters the buffer tank through the oil unloading pipe 1 for temporary storage. The oil unloading pipe 1 is a corrugated pipe, which is convenient for adjusting the length and layout angle. A sealing cover 11 can be installed at the end of the oil unloading pipe 1 connected to the oil truck to prevent external dirt from entering the oil unloading pipe 1.

[0049] The support assembly 2 is used to support the oil unloading pipe 1 to prevent the oil unloading pipe 1 from being bent due to gravity. Refer to Figure 2 , the support assembly 2 includes a support column 22 and a support plate 21, and the support column 22 is fixedly connected to the lower side of the support plate 21.

[0050] The support column 22 is a telescopic structure. The support column 22 includes a support tube 221 fixedly connected to the lower side of the support plate 21. One end of the support tube 221 is fixedly connected to the support column 22, and the other end is sleeved on a fixed rod 222. One end of the fixed rod 222 passes through the support tube 221, and the other end contacts the ground. A support disc 224 is fixedly connected to the end of the fixed rod 222 in contact with the ground, and the support disc 224 is used to increase the contact area between the fixed rod 222 and the ground. Among them, an adjusting screw 223 is passed through the support tube 221, and the adjusting screw 223 is threadedly connected to the tube wall of the support tube 221. The end of the adjusting screw 223 penetrates into the support tube 221. After one end of the fixed rod 222 is inserted into the support tube 221, the adjusting screw 223 is turned, and the adjusting screw 223 presses against the fixed rod 222 to limit the length of the fixed rod 222 inserted into the support tube 221, so as to fix the service length of the support column 22 after adjusting the length of the support column 22.

[0051] And a plurality of support columns 22 are arranged on the lower side of the support plate 21, and the plurality of support columns 22 jointly support the support plate 21. The support assembly 2 can adjust the used position according to the actual size of the oil tanker, so as to support the unloading oil pipe 1 in a larger range and improve the stability of the support.

[0052] The support plate 21 is a semi-circular steel pipe with an upward opening. The unloading oil pipe 1 is placed on the support plate 21, and the support plate 21 supports the unloading oil pipe 1 to prevent the unloading oil pipe 1 from being longitudinally bent after being supported. Moreover, the support plate 21 is set as a semi-circular steel pipe type, and the unloading oil pipe 1 is embedded in the support plate 21. The support plate 21 also restricts the unloading oil pipe 1 laterally, and can effectively prevent the unloading oil pipe 1 from being bent laterally.

[0053] A moving plate 211 is also slidably connected to the support plate 21. The moving plate 211 is also a semi-circular steel pipe. When the moving plate 211 is arranged on the support plate 21, the outer wall of the moving plate 211 contacts the inner wall of the support plate 21. The moving plate 211 is arranged on the support plate 21 along the length direction of the support plate 21, and the moving plate 211 and the support plate 21 increase the total length of the moving plate 211 and the support plate 21 through sliding. When the unloading oil pipe 1 is installed on the support assembly 2 and is supported by the support assembly 2, the moving plate 211 and the support plate 21 jointly support the unloading oil pipe 1. When moving the position supported by the support assembly 2, the total length between the moving plate 211 and the support plate 21 can be increased to increase the support range of the unloading oil pipe 1, improve the support effect, and avoid the unloading oil pipe 1 from being bent. When the support column 22 supports the support plate 21, a group of support columns 22 are connected to the moving plate 211.

[0054] During the process of unloading oil with an oil tanker, first place the unloading oil pipe 1 on the support plate 21. The support plate 21 supports the unloading oil pipe 1. Then, move the support plate 21 through the support column 22, connect the unloading oil pipe 1 to the oil tanker, and then adjust the total length between the support plate 21 and the moving plate 211 so that the support assembly 2 stably supports the unloading oil pipe 1 between the oil tanker and the buffer tank, avoiding bending of the unloading oil pipe 1.

[0055] Refer to Figure 3 、 Figure 4 The lifting assembly 3 includes a bracket 31, a traction machine 32 installed on the bracket 31, and a pulling rope 33 installed on the traction machine 32. The lifting device is used to pull one end of the unloading oil pipe 1 so that one end of the unloading oil pipe 1 is lifted, enabling the remaining oil in the unloading oil pipe 1 to be poured into the buffer tank after unloading is completed.

[0056] The bracket 31 includes a vertical pipe 311 fixedly connected to the ground. The vertical pipe 311 is vertically arranged, and the length of the vertical pipe 311 is greater than the height of the buffer tank. A horizontal pipe 312 is fixedly connected to the end of the other end of the vertical pipe 311. The horizontal pipe 312 is horizontally arranged. A reinforcing pipe 313 is fixedly connected between the horizontal pipe 312 and the vertical pipe 311. One end of the reinforcing pipe 313 is fixedly connected to the horizontal pipe 312, and the other end is fixedly connected to the vertical pipe 311, so that the horizontal pipe 312, the vertical pipe 311, and the reinforcing pipe 313 form a triangular support, thus ensuring the stability of the bracket 31.

[0057] A connection groove 314 is formed on the lower side of the horizontal pipe 312 and is arranged along the length direction of the horizontal pipe 312. The connection groove 314 penetrates the outer wall of the horizontal pipe 312.

[0058] Refer to Figure 4 、 Figure 5 The upper end of the traction machine 32 is fixedly connected with a moving rod 34. The upper end of the moving rod 34 is fixedly connected with a moving steel ball 35. The moving steel ball 35 is arranged in the horizontal pipe 312. When the moving steel ball 35 is installed in the horizontal pipe 312, the moving rod 34 is located in the connection groove 314. The moving steel ball 35 can move along the length direction of the horizontal pipe 312. When the moving steel ball 35 moves, it drives the moving rod 34 and the traction machine 32 to move along the length direction of the horizontal pipe 312, thereby adjusting the arrangement position of the traction machine 32.

[0059] The pulling rope 33 is arranged on the traction machine 32, and the traction machine 32 drives the pulling rope 33 to extend or shorten. One end of the pulling rope 33 is fixed on the traction machine 32, and the other end is equipped with a hook 331. The hook 331 is used to hook the unloading oil pipe 1.

[0060] Refer to Figure 1 、 Figure 6, a filtering component 4 is installed between the oil unloading pipe 1 and the buffer tank. The filtering component 4 includes a filtering box 41 with openings at both the front and rear ends for connecting the filtering box 41 to the oil unloading pipe 1 and the buffer tank. A filter screen 42 arranged perpendicular to the oil flow direction is installed in the filtering box 41. During the oil transportation process, the oil will pass through the filter screen 42, and the filter screen 42 filters the oil to filter out the dirt in the oil.

[0061] The usage process of an enclosed oil unloading auxiliary device for a gathering and transportation station yard in an embodiment of this application is as follows: When the oil truck drives near the buffer tank for oil unloading, the staff first connects one end of the oil unloading pipe 1 to the oil outlet on the oil truck, and then adjusts the position and layout length of the support component 2 so that the support component 2 supports the oil unloading pipe 1 to ensure that the oil unloading pipe 1 is in a horizontal state and avoid bending of the oil unloading pipe 1. Then, the valve on the oil truck is opened, and the oil in the oil truck enters the oil unloading pipe 1 and then enters the buffer tank through the oil unloading pipe 1 and the filtering component 4.

[0062] When adjusting the position and layout length of the support component 2, by pulling the moving plate 211, the total length between the moving plate 211 and the support plate 21 is adjusted to stably support the oil unloading pipe 1. Then, the length of the support column 22 is adjusted to change the layout height of the support plate 21 so that the oil unloading pipe 1 can be adjusted to a height flush with the oil outlet on the oil truck, further avoiding bending of the oil unloading pipe 1.

[0063] After the oil unloading is completed, the oil unloading pipe 1 is separated from the oil outlet on the oil truck, and then the tractor 32 is started. The pulling rope 33 drives one end of the oil unloading pipe 1 to lift, making the height of the end of the oil unloading pipe 1 away from the buffer tank higher than the other end. The residual oil in the oil unloading pipe 1 enters the buffer tank under the action of its own gravity, so that the residual oil in the oil unloading pipe 1 can be cleaned. Moreover, after the oil unloading pipe 1 is separated from the oil truck, the sealing cover 11 can close the pipe orifice of the oil unloading pipe 1 at the end of the oil unloading pipe 1 to prevent external dirt from entering the oil unloading pipe 1.

[0064] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, so that a process, method, article, or equipment / device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent in these processes, methods, articles, or equipment / device.
