Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction equipment technology, and in particular to a mixed-transport booster device for negative pressure gas extraction. Background Technology

[0002] In the oil and gas extraction sector, negative pressure gas production technology is widely used because it can effectively improve the recovery rate of gas wells. In a negative pressure gas production system, the mixed-transport pressurization unit is the core equipment, mainly responsible for pressurizing and transporting the collected natural gas and liquid mixture, ensuring that the natural gas is smoothly transported from the gas well to the processing station or gathering and transmission pipeline network, thereby ensuring the continuity and efficiency of the entire gas production process.

[0003] However, traditional negative pressure gas extraction systems rely heavily on cranes for overall hoisting during relocation or adjustment, which presents numerous problems. Firstly, the hoisting process involves positioning and debugging the hoisting equipment, installing and inspecting the hoisting rigging, and other complex and time-consuming steps, reducing gas extraction efficiency and increasing production losses due to downtime. Secondly, hoisting operations require large equipment such as cranes and transport vehicles, which are expensive to rent or purchase. They also require specialized operators, transport personnel, and on-site supervisors, resulting in high labor costs. Furthermore, the hoisting process consumes large amounts of fuel and lubricating oil, further increasing relocation costs. This problem is even more pronounced in field or complex environments. Complex terrain and poor road conditions restrict the access and operation of large hoisting equipment. In the event of sudden changes in gas well production or equipment failure, traditional systems struggle to adjust their position promptly and respond quickly, leading to insufficient emergency response capabilities and impacting the continuity and safety of gas extraction operations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a mixed transmission and booster device for negative pressure gas extraction, so as to solve the problems of traditional devices relying on cranes for relocation and being complicated to operate.

[0005] Based on the above objectives, this utility model provides a mixed-transmission booster device for negative pressure gas extraction, comprising: a base frame and a mixed-transmission booster body. An integrated installation box is provided on one side of the base frame, and several hydraulic bases are installed on the other side of the base frame. The mixed-transmission booster body is disposed in the integrated installation box and includes a mixed-transmission pump, a gas-liquid mixing pipeline, and a booster unit, used to boost the collected gas-liquid mixture and transport it to the gas collection and transmission network.

[0006] A movable component is installed on one side of the base frame. The movable component is used to move the integrated installation housing of the equipment. The movable component includes several outer shells installed on one side of the base frame. A limit frame is fixedly installed inside the outer shell. A support column is slidably installed inside the limit frame. A moving wheel is installed on one side of the support column. A moving seat is slidably installed on one side of the limit frame. One end of the support column is slidably installed in the moving seat. A hydraulic cylinder is installed inside the outer shell. Its output end passes through the limit frame and is connected to the moving seat.

[0007] An opening and closing component is mounted on one side of the movable component and is used to cooperate in opening the movable component.

[0008] Preferably, a second slide groove is fixedly installed on one side of the limiting frame, and a slider is fixedly installed on one side of the movable seat, the slider being slidably installed in the second slide groove.

[0009] Preferably, a through hole is provided on one side of the limiting frame, the support column is slidably installed in the through hole, a connecting plate is fixedly installed at one end of the support column, a ball bearing is rotatably installed on one side of the connecting plate, a limiting hoop is installed on the through hole, a return spring is fixedly installed between the limiting hoop and the connecting plate, and the return spring is sleeved on the support column.

[0010] Preferably, the movable seat has a first sliding groove, one end of which has a limiting hole, and the ball is slidably installed in the first sliding groove, the ball being adapted to the limiting hole.

[0011] Preferably, the opening and closing assembly includes a closing plate slidably mounted on one side of the housing, a second slide rail symmetrically provided at one end of the housing, both sides of the closing plate slidably mounted in the second slide rail, a connecting block fixedly mounted on one side of the closing plate, a lock hole provided on the connecting block, a lock box fixedly mounted on one side of the housing, a lock pin slidably mounted in the lock box, and the lock pin being adapted to the lock hole.

[0012] Preferably, the lock box has a cavity, a connecting plate is fixedly installed on the lock post, the connecting plate is slidably installed in the cavity, a pressure spring is fixedly installed on one side of the connecting plate, the other end of the pressure spring is fixedly installed on one side of the cavity, the pressure spring is sleeved on the lock post, and a pull ring is installed on one side of the lock post.

[0013] Preferably, a first slide rail is fixedly installed on one side of the outer casing, and the symmetrical sides of the closing plate are slidably installed in the first slide rail.

[0014] The beneficial effects of this utility model are:

[0015] 1. This negative pressure gas production mixed-transport booster device, by setting up a mixed-transport booster main body in the integrated equipment installation box, consists of a mixed-transport pump, a gas-liquid mixing pipeline and a booster unit. Under negative pressure gas production conditions, the mixed-transport pump can fully mix and pressurize the gas-liquid mixture collected at the wellhead, and the booster unit further increases the pressure of the mixed-transport medium, enabling it to be smoothly transported to the gathering and transportation network or processing station. Through the synergistic effect of the above structures, this device can maintain the continuity and stability of the gas-liquid mixture flow, avoid transportation interruption due to insufficient pressure, and thus effectively improve the natural gas recovery rate and transportation efficiency.

[0016] 2. This negative pressure gas extraction and mixing booster device, by incorporating a movable component, allows for position adjustment or overall relocation of the equipment after installation without relying on a crane. When the mobile installation unit needs to be integrated, the hydraulic cylinder drives the movable seat to extend and retract the support column, thereby releasing the movable wheels and allowing the device to roll smoothly on the ground. This avoids the drawbacks of traditional methods that require the use of large hoisting machinery for transportation. It not only significantly reduces the consumption of manpower and material resources but also improves the mobility and flexibility of the equipment in complex field conditions. At the same time, the design of the limit frame, sliding groove, and return spring ensures the stability and safety of the movement process, enabling the equipment to provide reliable support while also enabling rapid relocation, thereby effectively improving the efficiency and on-site adaptability of the device.

[0017] 3. This negative pressure gas extraction and mixing booster device, through the installation of an opening and closing component, allows the outer shell to effectively seal and protect the internal moving components through the closing plate when not in operation. This prevents external dust, impurities, or rainwater from entering the internal structure and affecting the stable operation of the support mechanism. At the same time, when movement is required, the operator can quickly open the closing plate by simply unlocking it with a pull ring and slide it into the slide rail for temporary storage, providing ample space for the extension of the moving components and the release of the moving wheels. The entire process can be completed without complicated operations, featuring a simple structure and convenient operation. In addition, the cooperation between the locking pin and the locking hole, combined with the automatic return function of the pressure spring, ensures that the closing plate can be reliably locked when closed, preventing loosening caused by vibration or external force.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0030] like Figures 1 to 7 As shown, the system includes a base frame 2 and a mixed-transport pressurization body. One side of the base frame 2 is equipped with an integrated equipment mounting box 1, and the other side is equipped with several hydraulic bases 3. The mixed-transport pressurization body is housed within the integrated equipment mounting box 1 and includes a mixed-transport pump, a gas-liquid mixing pipeline, and a pressurization unit, used to pressurize the collected gas-liquid mixture and transport it to the collection and transportation network. A moving component is also included, installed on one side of the base frame 2, used to move the integrated equipment mounting box 1. Finally, an opening and closing component is installed on one side of the moving component, used to cooperate in opening the moving component.

[0031] During operation, the device is supported and fixed by the base frame 2. The integrated installation box 1 and the hydraulic base 3 are respectively installed on both sides of the base frame 2. The hydraulic base 3 provides stable support and necessary hydraulic assistance for the operation of the device. The integrated installation box 1 contains a mixing and pressurizing main body, which consists of a mixing pump, a gas-liquid mixing pipeline, and a pressurizing unit. During operation, the collected gas-liquid mixture flows through the gas-liquid mixing pipeline into the mixing pump. After initial mixing by pumping, it enters the pressurizing unit. The pressurizing unit increases the pressure of the mixture fluid to achieve stable pressure and flow, and finally efficiently delivers it to the collection and transportation network to meet subsequent transportation and processing needs. The device also has a moving component and an opening and closing component. The moving component is installed on one side of the base frame 2, which drives the integrated installation box 1 to adjust its position, realizing flexible movement and deployment of the device. The opening and closing component is located on the side of the moving component, which can... The device can be opened or closed with the movable components when needed, facilitating installation, inspection, and maintenance. The entire process achieves efficient pressurization and transportation of collected gas-liquid mixtures and flexible operation of the equipment. Notably, during operation, the collected gas-liquid mixture flows through the gas-liquid mixing pipeline into the mixing pump. After initial mixing, it enters the pressurization unit, which increases the pressure of the mixture and outputs it stably to the gathering and transportation network. The device is suitable for wellhead absolute pressure not lower than 0.3 MPa and gas-liquid ratio of 50:1 to 1500:1. The final output pressure can be adjusted according to the requirements of the gathering and transportation network and shall not exceed 2.5 MPa. The above structural limitations are based on the shape and construction of the product. The operation process description is used to clarify the fluid path and component coordination. Undefined connection methods may include bolted connections, welding, or flange sealing connections. Vibration damping and sealing components not detailed are standard configurations in the field.

[0032] like Figures 2 to 5As shown, the movable assembly includes several housings 4 mounted on one side of the base frame 2. A limiting frame 7 is fixedly installed inside each housing 4. A support column 16 is slidably installed inside each limiting frame 7. A moving wheel 6 is mounted on one side of each support column 16. A movable seat 9 is slidably installed on one side of each limiting frame 7. One end of the support column 16 is slidably installed inside the movable seat 9. A hydraulic cylinder 8 is installed inside each housing 4, with its output end passing through the limiting frame 7 and connected to the movable seat 9. A second slide groove 14 is fixedly installed on one side of each limiting frame 7, and a slider 12 is fixedly installed on one side of the movable seat 9. The slider 12 is slidably installed in the second slide groove 14. 4. Inside; a through hole 13 is provided on one side of the limiting frame 7, and a support column 16 is slidably installed in the through hole 13. A connecting plate 18 is fixedly installed at one end of the support column 16, and a ball bearing 19 is rotatably installed on one side of the connecting plate 18. A limiting clamp 15 is installed on the through hole 13, and a return spring 17 is fixedly installed between the limiting clamp 15 and the connecting plate 18. The return spring 17 is sleeved on the support column 16. A first sliding groove 10 is provided on the movable seat 9, and a limiting hole 11 is provided at one end of the first sliding groove 10. The ball bearing 19 is slidably installed in the first sliding groove 10, and the ball bearing 19 is adapted to the limiting hole 11.

[0033] During use, when the movement function needs to be activated, the moving seat 9 is first driven to move along the guide path set inside the limiting frame 7 by controlling the extension and retraction of the hydraulic cylinder 8. Since the moving seat 9 is fixedly connected to a slider 12 on one side and cooperates with the second slide groove 14, its movement is always restricted and guided by the slide groove, thereby ensuring the stable sliding of the moving seat 9 in the straight direction. When the moving seat 9 moves outward step by step under the push of the hydraulic cylinder 8, the support column 16 installed in the through hole 13 of the limiting frame 7 is forced to extend outward under the drive of the connecting plate 18 and the ball bearing 19. At this time, the ball bearing 19 slides synchronously in the first slide groove 10 and gradually moves to the limiting hole 11 along the slide groove trajectory. When the ball bearing 19 enters the limiting hole 11, it reliably limits and locks the support column 16, preventing it from loosening during load-bearing or movement. Simultaneously, the connecting disc 18, under the elastic force of the return spring 17, maintains an inward tendency to return, allowing the entire support column 16 to automatically retract and maintain its initial standby position when not under force. When the hydraulic cylinder 8 continuously pushes the moving seat 9 forward, because the moving seat 9 is designed as an irregular strip block, its movement trajectory forces the support column 16 to gradually shift to the outside of the housing 4. This allows the moving wheel 6 mounted on the support column 16 to be smoothly released from the covered space of the housing 4, achieving a transition from a hidden state to an exposed state, thereby enabling… The entire device can move smoothly on the ground using the casters 6. The extension and retraction of the hydraulic cylinders 8 allows for rapid deployment and relocation of the mobile components without the need for additional lifting tools when the equipment needs to be moved, significantly improving the device's on-site adaptability and ease of use. Notably, the casters 6 are preferably made of high-strength, wear-resistant materials, such as polyurethane-coated steel core wheels or solid rubber wheels, to ensure good wear resistance and load-bearing capacity under different ground conditions. The support column 16 is preferably made of high-strength alloy steel or thick-walled seamless pipe, and it is reliably fixed to the connecting plate 18 through an interference fit or threaded connection, maintaining stability even under heavy loads. If bending or loosening occurs, the ball bearings 19 on one side of the connecting plate 18, when rolling in the first slide groove 10, not only play a limiting role, but also reduce the friction between the support column 16 and the moving seat 9, improving the smoothness of the telescopic movement. In addition, the number of moving wheels 6 can be set according to the overall weight of the device and the size of the base frame 2. They are generally distributed in pairs or groups on opposite sides of the base frame 2 to achieve balanced force and stable support. When multiple moving wheels 6 are released at the same time and contact the ground, the device as a whole can be smoothly pushed or pulled on the horizontal surface, reducing the phenomenon of tilting or jamming caused by single-point force, thereby further improving the adaptability of the device in field operations or complex ground environments.

[0034] like Figure 6 , Figure 7As shown, the opening and closing assembly includes a closing plate 5 slidably mounted on one side of the outer casing 4. A second slide rail 23 is symmetrically provided at one end of the outer casing 4. The two sides of the closing plate 5 are slidably mounted in the second slide rail 23. A connecting block 20 is fixedly mounted on one side of the closing plate 5. A lock hole 21 is provided on the connecting block 20. A lock box 24 is fixedly mounted on one side of the outer casing 4. A lock pin 25 is slidably mounted in the lock box 24. The lock pin 25 is adapted to the lock hole 21. A cavity 29 is provided in the lock box 24. A connecting plate 28 is fixedly mounted on the lock pin 25. The connecting plate 28 is slidably mounted in the cavity 29. A pressure spring 26 is fixedly mounted on one side of the connecting plate 28. The other end of the pressure spring 26 is fixedly mounted on one side of the cavity 29. The pressure spring 26 is sleeved on the lock pin 25. A pull ring 27 is installed on one side of the lock pin 25. A first slide rail 22 is fixedly mounted on one side of the outer casing 4. The two symmetrical sides of the closing plate 5 are slidably mounted in the first slide rail 22.

[0035] During use, when the moving component needs to be in a non-working state, the closing plate 5 slides to one side of the housing 4 under the guidance of the first slide rail 22 and the second slide rail 23, thus covering the opening of the housing 4 and aligning the connecting block 20 on the closing plate 5 with the lock box 24 on one side of the housing 4. At this time, the locking pin 25 automatically enters the lock hole 21 on the connecting block 20 under the action of the pressure spring 26, thereby achieving reliable locking of the closing plate 5 and preventing the closing plate 5 from loosening due to external vibration or impact. When it is necessary to open the opening and closing component, the operator only needs to pull the pull ring 27 at one end of the locking pin 25, so that the locking pin 25 overcomes the elastic force of the pressure spring 26, disengages from the lock hole 21, and retracts into the cavity 29. At this time, the locking state of the closing plate 5 is released, and the operator can push the closing plate 5 to slide along the first slide rail 22 and the second slide rail 23 until the opening of the housing 4 is completely removed, thus providing space for the extension of the moving component and the release of the moving wheel 6. During the opening process, the connecting plate 28 slides synchronously under the drive of the locking pin 25, and the pressure spring 26 gradually compresses, ensuring that the locking pin 25 can automatically return to its original position under the action of elastic force after the pull ring 27 is released. When the closing plate 5 moves to the closed position again, the locking hole 21 and the locking pin 25 are re-aligned, and the locking pin 25 will automatically insert into the locking hole 21 under the action of the pressure spring 26, thereby restoring the reliable limit locking of the closing plate 5 and realizing the automatic closing of the device. After opening, the closing plate 5 can be placed in the first slide rail 22 for temporary storage. Since the first slide rail 22 is set perpendicular to the ground, the closing plate 5 can be placed in the first slide rail 22 for temporary storage without slipping. Through the setting of this opening and closing component, it can not only ensure that the moving component is effectively protected in the non-use state, preventing external debris from entering the shell 4 and affecting the normal operation of the support mechanism, but also quickly open and close when needed, simplifying the operation process and improving the safety and convenience of the overall device.
