Description

Technical Field

[0001] This invention relates to the technical field of oil drilling and production auxiliary equipment, and in particular to an automatic ignition device for oil extraction platforms. Background Technology

[0002] With social development, petroleum, as an important energy resource, plays a vital role in economic construction and people's daily lives. During oil drilling, gases from the formation often dissolve into the drilling fluid and return to the wellhead. These gases may contain flammable components, and if not handled promptly, leaks can pose a significant threat to the environment and personnel safety. Therefore, ignition devices are needed to burn off these flammable gases to ensure the safe conduct of drilling operations.

[0003] A Chinese patent application with patent number CN202221324580.6 discloses an automatic ignition combustion device for venting gas, comprising an exhaust gas delivery pipe and an ignition device. The exhaust gas delivery pipe has an inlet and an outlet. A connecting cylinder is connected to one end of the exhaust gas delivery pipe at the inlet. Flanges are provided at both ends of the connecting cylinder. The inlet is connected to the connecting cylinder through the flanges. A support assembly is fitted onto the flanges and is located on the ground. The support assembly is used to provide support for the flanges. The ignition device includes an ignition box, a diesel tank, an ignition control box, an ignition rod, an ignition high-voltage coil, a diesel delivery pipe, a diesel nozzle, and a positive pressure pipe. The ignition box is located at the outlet of the exhaust gas delivery pipe and is connected to the outside. The diesel tank is located on the ground. One end of the diesel delivery pipe is connected to the diesel tank, and the other end passes through the ignition box and is placed inside the ignition box.

[0004] Electronic ignition is expensive and not suitable for newly developed oil wells, while traditional ignition methods are more dangerous. When oil drilling platforms spray associated gas, they also spray mud and other debris. When debris falls on the steel cable or the first driven wheel, it makes the connection between the steel cable and the first driven wheel unstable, which in turn makes it difficult to safely and stably ignite the associated gas. After this problem is discovered, manual cleaning carries the risk of inhaling associated gas. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting components such as a drive rod, an arc rod, a striking plate, and a scraper, during the ignition stage, the drive rod strikes the passive rod, which in turn causes the arc rod to move against the spring. As the arc rod moves and the first driven wheel rotates, the scraper can pulse-scrape away impurities in the arc groove of the first driven wheel. During the stage when the ignition storage tank moves back to the starting point, the drive rod strikes the passive rod in the opposite direction, causing the striking plate to strike the upper steel cable, causing the mud on the steel cable to detach. In addition, the sharp end of the scraper can also lift and detach the mud in the arc groove of the first driven wheel, ensuring the stability of the steel cable during use.

[0019] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0020] Example 1 like Figures 1 to 5 As shown, this invention discloses an automatic ignition device for an oil extraction platform, comprising a steel cable 1, a suspension device 2 mounted on the steel cable 1, an active conveying unit 3 and a driven conveying unit 4 respectively mounted on both sides of the steel cable 1, the driven conveying unit 4 being located at the nozzle of the oil extraction platform, and the active conveying unit 3 being located away from the nozzle of the oil extraction platform, and a ignition storage tank being mounted at the lower end of the suspension device 2. The steel cable 1 is moved with the assistance of the active conveying unit 3, and during the movement of the steel cable 1, the driven conveying unit 4 assists in moving the steel cable 1. The movement of the steel cable 1 carries the ignition storage tank through the suspension device 2, moving the ignition storage tank to the oil extraction platform, so that the associated gas ejected from the nozzle of the oil extraction platform is ignited. The ignition treatment of associated gas is a commonly used low-cost and efficient treatment method in the prior art.

[0021] The active conveying unit 3 includes four mounting vertical rods 301. Each of the four mounting vertical rods 301 has a bottom crossbar 302, a middle crossbar 303, and a top crossbar 304. The mounting vertical rods 301 are welded to the bottom crossbars 302, middle crossbars 303, and top crossbars 304, forming a main frame and ensuring greater stability during operation.

[0022] A baffle 305 is provided between the bottom horizontal bar 302 and the mounting vertical bar 301. Hinges 306 are provided between the baffles 305 on the front and rear sides and the bottom horizontal bar 302. Limiting rings 307 are provided on the baffles 305 on the front and rear sides, and pins 308 are provided inside the limiting rings 307. Matching rings 309 that match the limiting rings 307 are provided on the mounting vertical bar 301. After the active conveying unit 3 is placed in the designated position, the four baffles 305 form a box shape with an opening at the top. Sand and gravel are filled into it to achieve the counterweight fixation of the active conveying unit 3. Other methods can also be used for fixation, such as fixing with rivets, to ensure that the active conveying unit 3 will not tip over during use. When the equipment is disassembled after use, the pins 308 are removed from the matching rings 309 to release the limiting of the baffles 305. The baffles 305 will rotate with the assistance of the hinges 306, so that the sand and gravel in the middle can be easily removed and released, improving the convenience and stability of the equipment.

[0023] A first installer 310 is provided on the middle crossbar 303. There are two first installers 310, and a first rotating shaft 311 is rotatably connected between the two first installers 310. A drive wheel 312 is provided on the first rotating shaft 311, and a drive handle 313 is provided at the end of the first rotating shaft 311. When the worker holds the drive handle 313 and rotates it, the first rotating shaft 311 will rotate. The rotation of the first rotating shaft 311 will drive the rotation of the drive wheel 312. The rotation of the drive wheel 312 will move the steel cable 1 with the assistance of friction, thereby providing power for the movement of the steel cable 1. At the same time, a motor can also be provided at the corresponding position of the middle crossbar 303. The motor will rotate the first rotating shaft 311, so that the movement of the steel cable 1 is stable and controllable.

[0024] A second mount 314 is provided at the upper end of the top crossbar 304. There are two second mounts 314, and a second rotating shaft 315 is rotatably arranged between the two second mounts 314. A second driven wheel 316 is provided on the second rotating shaft 315. The steel cable 1 is located outside the drive wheel 312, the first driven wheel 401 and the second driven wheel 316. The steel cable 1 forms a closed loop outside the drive wheel 312, the first driven wheel 401 and the second driven wheel 316. With the assistance of the second driven wheel 316, there is sufficient space at both the upper and lower ends of the steel cable 1 to suspend the tinder storage tank. Furthermore, an external tensioning device can be installed between the second driven wheel 316 and the drive wheel 312 to keep the steel cable 1 in a tensioned state between the drive wheel 312, the first driven wheel 401 and the second driven wheel 316, which helps to ensure the stable operation of the steel cable 1.

[0025] The driven conveying unit 4 includes a first driven wheel 401 and a mounting frame 408. There are two mounting frames 408, which are located at the nozzles of the oil drilling platform. A third installer 409 is installed on the mounting frame 408. There are two third installers 409, and a third rotating shaft 410 is rotatably connected between the two third installers 409. The first driven wheel 401 is located on the third rotating shaft 410. The steel cable 1 is located at one end of the oil drilling platform and is assisted by the first driven wheel 401 to ensure the stable use of the steel cable 1. The driven conveying unit 4 and the steel cable 1 are made of high-temperature resistant materials to ensure that after the associated gas is ignited, the steel cable 1 and the driven conveying unit 4 can still maintain stable operation and send the ignition storage tank back to the starting point.

[0026] The drive wheel 312, the first driven wheel 401 and the second driven wheel 316 are provided with arc-shaped grooves that match the steel cable 1. The arc-shaped grooves limit the movement of the steel cable 1, ensuring that the steel cable 1 will not detach from the drive wheel 312, the first driven wheel 401 and the second driven wheel 316, making the steel cable 1 more stable during use.

[0027] During the use of the present invention, the driven conveying unit 4 is installed at the corresponding position of the oil drilling platform. After the driving conveying unit 3 is placed at the designated position, a box shape with an upper opening is formed between the four baffles 305, and sand and gravel are filled into it, thereby achieving the counterweight fixation of the driving conveying unit 3.

[0028] Then, the steel cable 1 is sleeved outside the driving wheel 312, the first driven wheel 401 and the second driven wheel 316, and the steel cable 1 is kept in a tensioned state with the assistance of an external tensioning device.

[0029] When it is necessary to ignite the associated gas ejected from the oil drilling platform, the ignition source storage tank is hung at the lower end of the hanger 2. Then, the worker holds the driving handle 313 and rotates it, causing the first rotating shaft 311 to rotate. The rotation of the first rotating shaft 311 will drive the rotation of the driving wheel 312. The rotation of the driving wheel 312 will make the steel cable 1 move with the assistance of friction. The movement of the steel cable 1 will carry the ignition source storage tank towards the oil drilling platform. When the ignition source storage tank moves to the range of the associated gas ejection hole of the oil drilling platform, the combustible associated gas will be ignited by the ignition source in the ignition source storage tank.

[0030] After the combustion of the associated gas on the oil drilling platform is stable, the worker holds the driving handle 313 and rotates it in reverse, causing the rotation of the driving wheel 312 to become reverse, so that the steel cable 1 cooperates with the hanger 2 to carry the ignition source storage tank towards the position of the worker.

[0031] After the equipment is used up, the driven conveying unit 4 will not be disassembled, only the driving conveying unit 3 will be disassembled. During the disassembly process, the pin 308 is taken out from the mating ring 309 to release the limit of the baffle 305. The baffle 305 will rotate with the assistance of the hinge 306, so that the sand and gravel in the middle can be conveniently taken out and released, and then the equipment can be conveniently moved and disassembled.

[0032] Embodiment 2 Based on the automatic ignition device for an oil exploitation platform in the above-mentioned Embodiment 1, during its use, due to environmental limitations and the driven conveying unit 4 being continuously installed on the oil drilling platform without disassembly, when the oil drilling platform ejects associated gas, it also ejects sundries such as mud. When the sundries fall on the steel cable 1 or the first driven wheel 401, the cooperation between the steel cable 1 and the first driven wheel 401 will become unstable, and then it will be difficult to safely and stably ignite the associated gas subsequently. After discovering this problem, manual cleaning has the risk of inhaling the associated gas. Therefore, the following technical solutions are proposed: As Figures 1 to 6As shown, a drive rod 402 is provided on the side of the first driven wheel 401, and a limit sleeve 403 is provided on the side of the first driven wheel 401. An arc-shaped rod 404 is slidably arranged inside the limit sleeve 403. A striking plate 405 is provided at the upper end of the arc-shaped rod 404, and a limit plate 406 is provided at the lower end of the arc-shaped rod 404. A spring is provided between the limit plate 406 and the limit sleeve 403. A scraper is provided at the lower end of the limit plate 406. A passive rod 407 is rotatably arranged on the side of the arc-shaped rod 404 via a torsion spring. When the steel cable 1 moves the tinder storage tank toward the first driven wheel 401, the first driven wheel 401 rotates clockwise. During the rotation of the first driven wheel 401, the drive rod 402 strikes the passive rod 407, thereby causing the arc-shaped rod 404 to rotate clockwise. 04. Overcoming the effect of the spring, the scraper moves. As the arc rod 404 moves and the first driven wheel 401 rotates, the scraper can perform pulse scraping of impurities in the arc groove of the first driven wheel 401, effectively improving the scraping effect. When the first driven wheel 401 rotates counterclockwise, the associated gas of the driven conveying unit 4 and the steel cable 1 has been heated for a certain period of time, and the mud on them has dried. When the first driven wheel 401 rotates counterclockwise, the drive rod 402 strikes the passive rod 407 upward, causing the striking plate 405 at the upper end of the arc rod 404 to strike the upper end of the steel cable 1, causing the mud on the steel cable 1 to detach. The sharp end of the scraper can also lift and detach the mud in the arc groove of the first driven wheel 401.

[0033] An N-shaped frame 411 is provided between the two mounting crossbeams 408, and a limiting sleeve 403 is provided on the N-shaped frame 411. With the assistance of the N-shaped frame 411, the stability of the limiting sleeve 403 during use is ensured.

[0034] During the use of this invention, in the ignition stage, when the steel cable 1 carrying the ignition source storage container moves towards the first driven wheel 401, the first driven wheel 401 rotates clockwise. During the rotation of the first driven wheel 401, the drive rod 402 strikes the passive rod 407, which in turn causes the arc-shaped rod 404 to move against the spring. As the arc-shaped rod 404 moves and the first driven wheel 401 rotates, the scraper can perform pulse-like scraping of impurities in the arc-shaped groove of the first driven wheel 401, effectively improving the scraping effect and ensuring the stability of the steel cable 1 during movement.

[0035] After the associated gas is ignited and is burning stably, the ignition storage tank needs to be moved back to the starting point. At this time, when the first driven wheel 401 rotates counterclockwise, the associated gas ignited in the driven conveying unit 4 and the steel cable 1 has been heated for a certain period of time, and the mud on it has dried. When the first driven wheel 401 rotates counterclockwise, the drive rod 402 strikes the passive rod 407 upward, causing the striking plate 405 at the upper end of the arc rod 404 to strike the upper end of the steel cable 1, causing the mud on the steel cable 1 to fall off. In addition, the sharp end of the scraper can also lift the mud in the arc groove of the first driven wheel 401 and remove it, ensuring the stability of the movement of the steel cable 1.

[0036] The main function achieved by this invention is as follows: By setting up components such as a drive rod 402, an arc rod 404, a striking plate 405, and a scraper, during the ignition stage, the drive rod 402 strikes the passive rod 407, which in turn causes the arc rod 404 to move against the spring. As the arc rod 404 moves and the first driven wheel 401 rotates, the scraper can perform pulse-like scraping of impurities in the arc groove of the first driven wheel 401. During the stage when the ignition storage tank moves back to the starting point, the drive rod 402 strikes the passive rod 407 in the opposite direction, causing the striking plate 405 to strike the upper end of the steel cable 1, causing the mud on the steel cable 1 to detach. In addition, the sharp end of the scraper can also lift and detach the mud in the arc groove of the first driven wheel 401, ensuring the stability of the steel cable 1 during use.

[0037] The automatic ignition device for oil drilling platforms of the present invention can be installed, connected, or set in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effects.
