Description

Technical Field

[0001] The utility model relates to the technical field of aviation kerosene storage equipment, in particular to an emergency release device for an aviation kerosene tank on an offshore platform. Background Art

[0002] Aviation kerosene tanks are square or round tanks used to store aviation kerosene or other volatile liquids. They are usually suitable for refueling vehicles and machines within enterprises and factories, or for refueling during oil product experiments. The main components of aviation kerosene tanks include tank bodies, oil pumps, liquid level gauges, breathing valves and accessories. The specific volume and flow rate can be customized according to customer requirements and on-site conditions.

[0003] When a fire occurs around the aviation kerosene skid, the aviation kerosene tank needs to be released into the sea to avoid unnecessary losses. However, during the release process, the eye at the tail of the cable is usually manually fixed to the emergency release hook of the aviation kerosene tank, and then the aviation kerosene tank is lifted and released into the sea, which makes the emergency release operation of the aviation kerosene tank very cumbersome and causes the aviation kerosene tank to be unable to be quickly released into the sea. If the fire is too large or spreads very quickly, it is easy to cause greater losses. Summary of the invention

[0004] The utility model aims to provide an emergency release device for an aviation kerosene tank on an offshore platform, which can quickly release the aviation kerosene tank into the sea to avoid unnecessary losses in case of fire.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An emergency release device for aviation kerosene tanks on an offshore platform comprises a right bracket and a left bracket, the right bracket comprising a first upper frame and a first lower frame which are arranged vertically, the left bracket comprising a second upper frame and a second lower frame which are arranged vertically, the fitting surfaces of the first upper frame and the first lower frame, and the fitting surfaces of the second upper frame and the second lower frame are all inclined surfaces, a connecting rod mechanism is provided between the first lower frame and the second lower frame, one end of the connecting rod mechanism is rotatably connected to the cross beam of the first lower frame through a first rotating shaft, and the other end of the connecting rod mechanism is rotatably connected to the cross beam of the second lower frame through a second rotating shaft, a first stopper is provided on the first rotating shaft, the first stopper abuts against the side of the cross beam of the first upper frame, a second stopper is provided on the second rotating shaft, the second stopper abuts against the side of the cross beam of the second upper frame, and a hydraulic cylinder for driving the connecting rod mechanism to swing is provided on the first lower frame.

[0007] Furthermore, the connecting rod mechanism includes a first crank, a second crank and a connecting rod, one end of the first crank is hinged to one end of the connecting rod, the other end of the first crank is connected to the first rotating shaft, one end of the second crank is hinged to the other end of the connecting rod, the other end of the second crank is connected to the second rotating shaft, and the output end of the hydraulic cylinder is arranged on the first crank.

[0008] Furthermore, it also includes a hydraulic pump and a hydraulic pipeline assembly, and the hydraulic pump is connected to the hydraulic cylinder through the hydraulic pipeline assembly.

[0009] Furthermore, the hydraulic cylinder is a double-acting hydraulic cylinder, and is provided with a first input end and a second input end connected to the interior thereof, the hydraulic pipeline assembly comprises a first oil pipeline, a second oil pipeline, a first two-position three-way valve and a second two-position three-way valve, the hydraulic pump is a manual hydraulic pump, and the input end of the hydraulic pump is provided with a pressure rod, the output end of the hydraulic pump and the first input end of the hydraulic cylinder are connected to each other through the first oil pipeline, the first two-position three-way valve is arranged on the first oil pipeline, the output end of the hydraulic pump and the second input end of the hydraulic cylinder are connected to each other through the second oil pipeline, and the second two-position three-way valve is arranged on the second oil pipeline.

[0010] The beneficial effects of the utility model are as follows: both the first upper shelf and the second upper shelf can be used to assemble aviation kerosene tanks. When a fire occurs on the offshore platform, the hydraulic cylinder is used to push the connecting rod mechanism, and the two ends of the connecting rod mechanism respectively rotate the first rotating shaft and the second rotating shaft, thereby driving the first stop block and the second stop block to swing downward. When the first stop block no longer abuts against the cross beam of the first upper shelf and the second stop block no longer abuts against the cross beam of the second upper shelf, the aviation kerosene tank slides into the sea along with the first upper shelf and the second upper shelf respectively along the inclined surface of the first lower shelf and the inclined surface of the second lower shelf under the action of gravity. Even if the fire is too large to dismantle the transportation pipeline of the aviation kerosene tank, the relevant transportation pipeline can be disconnected when the first upper shelf and the second upper shelf are detached, thereby ensuring that the aviation kerosene tank is quickly released into the sea, avoiding unnecessary losses when the fire is too large or the fire spreads very quickly.

[0013] The technical solutions in the embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0014] like Figure 1and Figure 2 As shown, an emergency release device for aviation kerosene tanks on an offshore platform includes a right bracket 1 and a left bracket 2. The right bracket 1 includes a first upper shelf 101 and a first lower shelf 102 arranged vertically, and the left bracket 2 includes a second upper shelf 201 and a second lower shelf 202 arranged vertically. The fitting surfaces of the first upper shelf 101 and the first lower shelf 102, and the fitting surfaces of the second upper shelf 201 and the second lower shelf 202 are all inclined surfaces. A connecting rod mechanism 3 is provided between the first lower shelf 102 and the second lower shelf 202. One end of the connecting rod mechanism 3 is rotatably connected to the cross beam of the first lower frame 102 through the first rotating shaft 4, and the other end of the connecting rod mechanism 3 is rotatably connected to the cross beam of the second lower frame 202 through the second rotating shaft 5. The first rotating shaft 4 is provided with a first stopper 6, and the first stopper 6 abuts against the side of the cross beam of the first upper frame 101. The second rotating shaft 5 is provided with a second stopper 7, and the second stopper 7 abuts against the side of the cross beam of the second upper frame 201. The first lower frame 102 is provided with a hydraulic cylinder 8 for driving the connecting rod mechanism 3 to swing.

[0015] In this embodiment, based on the structural design of the right bracket 1, the first upper shelf 101 can be used to assemble the marine kerosene tank 11. The first upper shelf 101 and the first lower shelf 102 are both arranged up and down. The fitting surfaces of the first upper shelf 101 and the first lower shelf 102 are inclined surfaces. The first rotating shaft 4 is rotatably connected to the first lower shelf 102. The first stopper 6 located on the first rotating shaft 4 will resist the crossbeam of the first upper shelf 101, ensuring that the first upper shelf 101 can be stably placed on the upper surface of the first upper shelf 101. When a fire occurs on the offshore platform, the hydraulic cylinder 8 is started, and the hydraulic cylinder 8 The connecting rod mechanism 3 is pushed and swung, and the end of the connecting rod mechanism 3 drives the first rotating shaft 4 to rotate, and the first rotating shaft 4 drives the first stopper 6 to swing downward, and the first stopper 6 no longer resists the crossbeam of the first upper shelf 101. Under the action of gravity, the marine kerosene tank 11 slides downward along the inclined surface of the first lower shelf 102 together with the first upper shelf 101, and detaches from the first lower shelf 102, so that the marine kerosene tank 11 is quickly released into the sea to avoid unnecessary losses when the fire is too large or the fire spreads very quickly. The right bracket 1 and the left bracket 2 have the same working principle, which will not be repeated here.

[0016] The connecting rod mechanism 3 includes a first crank 301, a second crank 302 and a connecting rod 303. One end of the first crank 301 is hinged to one end of the connecting rod 303, and the other end of the first crank 301 is connected to the first rotating shaft 4. One end of the second crank 302 is hinged to the other end of the connecting rod 303, and the other end of the second crank 302 is connected to the second rotating shaft 5. The output end of the hydraulic cylinder 8 is arranged on the first crank 301. The hydraulic cylinder 8 can push or pull the first crank 301 to make the first crank 301 swing. The swinging first crank 301 can not only drive the first rotating shaft 4 to rotate, but also drive the second rotating shaft 5 to rotate through the connecting rod 303, and finally the first stopper 6 and the second stopper 7 can swing downward at the same time, so as to realize the rapid release of the marine kerosene tank 11 into the sea.

[0017] It also includes a hydraulic pump 9 and a hydraulic pipeline assembly 10, wherein the hydraulic pump 9 is connected to the hydraulic cylinder 8 through the hydraulic pipeline assembly 10. The hydraulic pump 9 provides hydraulic oil to the hydraulic cylinder 8 through the hydraulic pipeline assembly 10 to drive the hydraulic cylinder 8.

[0018] The hydraulic cylinder 8 is a double-acting hydraulic cylinder 8, and is provided with a first input end 801 and a second input end 802 connected to the interior thereof. The hydraulic pipeline assembly 10 includes a first oil pipeline 1001, a second oil pipeline 1002, a first two-position three-way valve 1003 and a second two-position three-way valve 1004. The hydraulic pump 9 is a manual hydraulic pump, and the input end of the hydraulic pump 9 is provided with a pressure rod 901. The output end of the hydraulic pump 9 and the first input end 801 of the hydraulic cylinder 8 are connected to each other through the first oil pipeline 1001. The first two-position three-way valve 1003 is arranged on the first oil pipeline 1001. The output end of the hydraulic pump 9 and the second input end 802 of the hydraulic cylinder 8 are connected to each other through the second oil pipeline 1002. The second two-position three-way valve 1004 is arranged on the second oil pipeline 1002.

[0019] When it is necessary to control the hydraulic cylinder 8, the switch of the first two-position three-way valve 1003 is rotated to the left position, the second two-position three-way valve 1003 remains stationary, and then the pressure rod 901 is lifted up to the 90° position and then pressed down. The operation is repeated many times, and the hydraulic oil in the hydraulic pump 9 can be injected into the hydraulic cylinder 8 through the first oil pipe 1001 and the first input end 801 in turn. The output end of the hydraulic cylinder 8 is fully extended, thereby pushing the connecting rod mechanism 3 to realize the rapid release of the marine kerosene tank 11 into the sea; when the right bracket 1 and the left bracket 2 need to be reassembled with the marine kerosene tank 11, the switch of the first two-position three-way valve 1003 is rotated to the middle side position, and the hydraulic oil will The pressure is released and flows back from the hydraulic cylinder 8 to the hydraulic pump 10, which is then continued to be rotated to the right position, closing the first two-position three-way valve 1003, operating the switch of the second two-position three-way valve 1003, and similarly lifting the pressure rod 901 upward to a 90° position and then pressing it down. The operation is repeated many times, and the hydraulic oil in the hydraulic pump 9 is injected into the hydraulic cylinder 8 through the second oil pipe 1002 and the second input end 802 in turn, so that the output end of the hydraulic cylinder 8 is fully retracted, and the first stopper 6 and the second stopper 7 are returned to their original positions through the connecting rod mechanism 3 to resist the first upper shelf 101 and the second upper shelf 201. The overall design realizes remote control of the hydraulic cylinder 8.
