Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically a cleaning device for an aviation fuel sampler. Background Technology

[0002] In the aviation industry, fuel quality is one of the key factors affecting flight safety. As a crucial piece of equipment for fuel sampling, the aviation fuel sampler is widely used in fuel refueling operations to ensure that the fuel meets quality standards.

[0003] An aviation fuel sampler is a device used for sampling aviation fuel. It allows for the convenient acquisition of fuel samples without affecting fuel quality, enabling quality testing and analysis. The primary function of an aviation fuel sampler is to ensure the quality and safety of aviation fuel, making it an essential tool in aviation maintenance.

[0004] However, during the collection of aviation fuel using fuel samplers, impurities and oil stains in the fuel can easily remain inside the sampler, affecting the accuracy of the sampling. Therefore, maintaining the sampler and keeping its interior clean has become an important task. Current technology typically relies on manual cleaning of fuel samplers. However, when cleaning fuel samplers manually, oil stains accumulate on the internal sidewalls of the sampler. Therefore, it is difficult to thoroughly clean the internal oil stains manually, especially when stubborn dirt or oil stains are present inside the sampler.

[0005] Furthermore, if oil stains accumulate on the inner sidewalls of the fuel sampler for an extended period, manual cleaning will take more time and result in low cleaning efficiency.

[0006] In summary, existing technologies for manually cleaning aviation fuel samplers suffer from the problems of difficulty in thoroughly cleaning the internal oil contaminants and low cleaning efficiency. Utility Model Content

[0007] The purpose of this invention is to solve the problems of difficulty in cleaning the internal oil stains of aviation fuel samplers and low cleaning efficiency when cleaning them manually in the prior art.

[0008] To address the aforementioned problems, this utility model provides a cleaning device for an aviation fuel sampler, comprising a frame and a cleaning assembly mounted on the frame. The cleaning assembly includes a cleaning component and a lifting component. The cleaning component includes a driving component and a cleaning head that is driven to the driving end of the driving component. The cleaning head is disposed within the placement space of the frame and inside the aviation fuel sampler with its opening facing upwards. The driving end of the driving component is disposed on the frame, extends towards the placement space, and is driven to the cleaning head, thereby rotating the cleaning head and cleaning the inner wall of the aviation fuel sampler.

[0009] Furthermore, the lifting component is mounted on the frame, located between the placement space and the drive component, and the distance between the drive component and the placement space can be adjusted in the height direction of the frame to adjust the height position of the cleaning head inside the aviation fuel sampler.

[0010] Using the above technical solution, when cleaning the aviation fuel sampler, the sampler is placed in a storage space, and the cleaning head is inserted into its interior. A lifting mechanism descends, causing the cleaning component to move downwards in the vertical direction, allowing the cleaning head to reach the lower part of the sampler's interior. A drive component rotates the cleaning head to clean oil stains in the lower part of the sampler's interior, such as the bottom and lower sides of the inner wall. Conversely, when the lifting mechanism rises, the cleaning component moves upwards in the vertical direction, allowing the cleaning head to reach the upper part of the sampler's interior. Again, a drive component rotates the cleaning head to clean oil stains in the upper part of the sampler's interior, such as the upper sides of the inner wall. This cleaning device thoroughly cleans the interior of the aviation fuel sampler and improves cleaning efficiency.

[0011] In summary, this cleaning device, when cleaning the aviation fuel sampler, changes the position of the cleaning component in the height direction through the lifting component, and drives the cleaning head to rotate, thus cleaning every part of the inner wall of the aviation fuel sampler quickly and efficiently. Therefore, this cleaning device has the advantages of thoroughly cleaning the inside of the aviation fuel sampler, thereby improving the cleanliness of the inside of the aviation fuel sampler, greatly reducing the residual oil inside the aviation fuel sampler, and having high cleaning efficiency.

[0012] One arrangement of the cleaning device for an aviation fuel sampler, to ensure the stability of the lifting component when adjusting the distance between the driving component and the placement space, includes a frame comprising a base and a support frame. In the height direction, the base is located directly above the support frame, and the support frame defines the placement space. The driving component is fixedly mounted on the base. Furthermore, the lifting component includes multiple lifting members, which are spaced apart along the width direction of the frame between the base and the support frame. One end of each lifting member is fixedly connected to the support frame, and the other end is fixedly connected to the base, for adjusting the distance between the support frame and the base in the height direction, thereby adjusting the distance between the placement space and the driving component in the height direction.

[0013] One configuration of the cleaning device for an aviation fuel sampler, considering that aviation fuel is a flammable substance, ensures the safety of the cleaning device during operation by locating a base that can move vertically above a support frame. The driving component is a forward and reverse cylinder with a drive shaft extending vertically. The forward and reverse cylinders are fixedly mounted on the base, and their driving ends are connected to the cleaning head. Multiple lifting components are configured as multiple lifting cylinders, with one end of each cylinder fixedly connected to the top of the support frame and the other end fixedly connected to the bottom of the base. The lifting cylinders adjust the position of the forward and reverse cylinders in the vertical direction to adjust the height of the cleaning head inside the aviation fuel sampler.

[0014] Furthermore, in one configuration of the cleaning device for the aviation fuel sampler, since the cleaning fluid still contains aviation fuel after cleaning, the cleaning device also includes a recovery pipe. A second access port adapted to the recovery pipe is provided on the first mounting plate. One end of the recovery pipe connects to an external recovery device, and the other end extends through the second access port into the interior of the aviation fuel sampler placed in the placement space, near the bottom wall of the sampler. After cleaning, the cleaning fluid is recovered to the external recovery device via the recovery pipe, and the aviation fuel is separated from the cleaning fluid by the external recovery device, reducing resource waste. It should be understood that the external recovery device can be an oil separator, etc. Attached Figure Description

[0024] An aviation fuel sampler is a device used for sampling aviation fuel. It allows for the convenient acquisition of fuel samples without affecting fuel quality, enabling quality testing and analysis. The primary function of an aviation fuel sampler is to ensure the quality and safety of aviation fuel, making it an essential tool in aviation maintenance.

[0025] In existing technologies, cleaning aviation fuel samplers typically relies on manual labor. However, when cleaning aviation fuel samplers manually, it is difficult to completely remove the oil sludge from the inside of the sampler due to the oil deposits that accumulate on the inner sidewalls. This is especially true when there are stubborn dirt deposits inside the sampler, such as oil sludge that has been deposited and adhered to the inner sidewalls for a long time. In such cases, it is very difficult to clean the inside of the sampler manually, and the cleaning efficiency is low.

[0026] To address the aforementioned problems, this utility model provides a cleaning device for an aviation fuel sampler. This device, when cleaning the aviation fuel sampler, uses a lifting component to change the position of the cleaning component in the vertical direction, causing the driving component to rotate the cleaning head. This allows for the thorough cleaning of oil stains from every part of the aviation fuel sampler's interior, quickly and efficiently. Therefore, it has the advantages of completely cleaning the interior of the aviation fuel sampler, thereby improving the cleaning effect, significantly reducing residual oil stains inside the sampler, and achieving high cleaning efficiency.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the overall structure of the cleaning device 1 of the aviation fuel sampler 40 provided in the embodiment of this utility model will be described first.

[0029] A cleaning device 1 for an aviation fuel sampler 40 includes a frame 10 and a cleaning assembly 20 mounted on the frame 10. The cleaning assembly 20 includes a cleaning component 21 and a lifting component 22.

[0030] Specifically, the cleaning component 21 includes a drive component 200 mounted on the frame 10 and a cleaning head 201 connected to the drive end of the drive component 200. The cleaning head 201 is disposed in the placement space 11 of the frame 10 and in the aviation fuel sampler 40 with its opening facing upward. The drive end of the drive component 200 is disposed on the frame 10, extends toward the placement space 11 and is connected to the cleaning head 201, thereby rotating the cleaning head 201 and cleaning the inner wall of the aviation fuel sampler 40.

[0031] More specifically, the lifting component 22 is mounted on the frame 10, located between the placement space 11 and the drive component 200, and can adjust the distance between the drive component 200 and the placement space 11 in the height direction 50 of the frame 10 to adjust the height position of the cleaning head 201 inside the aviation fuel sampler 40.

[0032] More specifically, the working principle of this cleaning device 1 is as follows: When cleaning the fuel sampler 40, the fuel sampler 40 is placed in the placement space 11, and the cleaning head 201 is extended into the interior of the fuel sampler 40. The lifting component 22 descends, causing the cleaning component 21 to move downwards in the height direction 50, so that the cleaning head 201 extends into the lower part of the interior of the fuel sampler 40. The driving component 200 drives the cleaning head 201 to rotate, thereby cleaning the oil stains in the lower part of the interior of the fuel sampler 40 placed in the placement space 11, such as fuel samples. The bottom and lower parts of the side walls of the inner wall of the fuel sampler 40; when the lifting component 22 rises, the cleaning component 21 moves upward in the height direction 50, so that the cleaning head 201 extends into the upper part of the interior of the fuel sampler 40. The driving component 200 drives the cleaning head 201 to rotate, thereby cleaning the oil stains in the upper part of the interior of the fuel sampler 40 placed in the placement space 11, such as the upper part of the side walls of the inner wall of the fuel sampler 40; through this working method, the interior of the fuel sampler 40 can be completely cleaned, and the cleaning efficiency is improved.

[0033] It should be understood that when the sampler is small in size, when the cleaning head 201 is cleaning the inner wall of the sampler, it is not necessary to adjust the distance between the drive member 200 and the placement space 11 in the height direction 50 of the frame 10 by the lifting component 22. The inner wall of the sampler can be cleaned simply by driving the cleaning head 201 to rotate by the drive member 200.

[0034] In summary, the advantages of this cleaning device 1 are as follows: When cleaning the fuel sampler 40, the cleaning device 1 changes the position of the cleaning component 21 in the height direction 50 by means of the lifting component 22, and the driving component 200 drives the cleaning head 201 to rotate, which can clean every part of the fuel sampler 40 quickly and efficiently. Therefore, this cleaning device 1 has the advantages of completely cleaning the inside of the fuel sampler 40, thereby improving the cleanliness of the inside of the fuel sampler 40, greatly reducing the residual oil in the inside of the fuel sampler 40, and having high cleaning efficiency.

[0035] The following provides a further explanation of the structure and arrangement of the frame 10, lifting component 22, and cleaning component 21.

[0036] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the frame 10 includes a base 100 and a support frame 101. The base 100 has a plate-like structure and is horizontally arranged along the width direction 60 of the frame 10. In the height direction 50, the base 100 is located directly above the support frame 101, and the support frame 101 defines a placement space 11. The drive member 200 is fixedly installed on the base 100.

[0037] Specifically, in one feasible embodiment, the lifting component 22 includes a plurality of lifting members 202. These lifting members 202 are spaced apart along the width direction 60 of the frame 10 between the base 100 and the support frame 101. One end of each lifting member 202 is fixedly connected to the support frame 101, and the other end is fixedly connected to the base 100. This allows for adjusting the distance between the support frame 101 and the base 100 in the height direction 50, thereby adjusting the distance between the placement space 11 and the driving member 200 in the height direction 50. It should be understood that the number of lifting members 202 can be 2, 3, 5, etc., and this embodiment does not limit the number.

[0038] More specifically, by setting the lifting component 22 as multiple lifting components 202, when the support frame 101 is fixedly installed on the aviation fuel sampling equipment, the base 100 can be moved relative to the support frame 101 in the height direction 50 by the lifting of multiple lifting components 202, and when the linkage drive component 200 drives the cleaning head 201 to move in the height direction 50, the stability is high and there will be no shaking, thus avoiding the risk of the cleaning head 201 hitting the inner wall of the aviation fuel sampler 40.

[0039] Alternatively, in another feasible implementation, the base 100 can be fixedly installed on the aviation fuel sampling equipment. In this case, the support frame 101 can be moved relative to the base 100 in the height direction 50 by raising and lowering multiple lifting components 202, which also has the advantage of high stability.

[0040] Furthermore, in one feasible implementation, such as Figure 2 As shown, the support frame 101 includes a first mounting plate 102, a second mounting plate 103 and a plurality of connecting rods (not shown in the figure). In the height direction 50, the first mounting plate 102 is located directly above the second mounting plate 103. One end of each of the plurality of connecting rods is fixed to the first mounting plate 102 and detachably connected, and the other end is fixed to the second mounting plate 103 and detachably connected.

[0041] Specifically, the first mounting plate 102, the second mounting plate 103 and a plurality of connecting rods surround and form a placement space 11. Furthermore, along the height direction 50, the first mounting plate 102 has a first passage opening, through which the cleaning head 201 extends into the interior of the aviation fuel sampler 40 placed in the placement space 11.

[0042] More specifically, when it is necessary to place the fuel sampler 40 within the storage space, the second mounting plate 103 can be removed, aligning the opening of the fuel sampler 40 with the cleaning head 201, and inserting it into the storage space 11 along the height direction 50. The opening of the fuel sampler 40 is then placed against the first mounting plate 102. The second mounting plate 103 is then installed onto the multiple connecting rods. It should be understood that both the first mounting plate 102 and the second mounting plate 103 are plate-shaped structures and are horizontally arranged along the width direction 60 of the frame 10; the number of connecting rods can be 2, 4, 6, etc.

[0043] Optionally, in another feasible embodiment, the second mounting plate 103 is further provided with a limiting groove on the side near the first mounting plate 102 that is adapted to the circumferential dimension of the fuel sampler 40. When the fuel sampler 40 is placed in the placement space 11, the fuel sampler 40 can be limited in the width direction 60, avoiding the risk of the fuel sampler 40 shaking. In addition, the other end of the multiple connecting rods is provided with a threaded section, and the second mounting plate 103 is provided with multiple mounting holes that correspond to and are adapted to the multiple connecting rods. When the fuel sampler 40 is placed in the placement space 11, the second mounting plate 103 is installed with the multiple connecting rods through the multiple mounting holes, and the two ends of the fuel sampler 40 in the height direction 50 respectively abut against the side walls of the first mounting plate 102 and the second mounting plate 103. Then, the second mounting plate 103 is fastened with bolts, thereby avoiding the risk of the fuel sampler 40 shaking in the height direction 50.

[0044] Furthermore, in one feasible implementation, such as Figure 2 As shown, since aviation fuel is a flammable substance, to ensure the safety of the cleaning device 1 during operation, the base 100 is movably positioned above the support frame 101 along the height direction 50. When the cleaning device 1 is fixedly installed on the aviation fuel sampling equipment via the support frame 101, the space occupied by the aviation fuel sampling equipment can be reduced. The driving component 200 is a positive and negative cylinder 203 with a drive shaft extending along the height direction 50. The positive and negative cylinder 203 is fixedly installed on the base 100, and the driving end of the positive and negative cylinder 203 is connected to the cleaning head 201. The multiple lifting components 202 are configured as multiple lifting cylinders 204. One end of the lifting cylinder 204 is fixedly connected to the top of the support frame 101, and the other end is fixedly connected to the bottom of the base 100. The lifting cylinder 204 adjusts the position of the positive and negative cylinder 203 in the height direction 50 to adjust the height position of the cleaning head 201 inside the aviation fuel sampler 40.

[0045] Specifically, the driving component 200 is configured to drive the cleaning head 201 with a forward and reverse cylinder 203, and the lifting component 202 is configured to drive the base 100 with a lifting cylinder 204. There is no source of fire or power, so safety can be guaranteed during the cleaning of the aviation fuel sampler 40.

[0046] Furthermore, in one feasible implementation, such as Figure 1 and Figure 2 As shown, the cleaning device 1 also includes an air intake component 24, which can supply gas to the forward and reverse cylinders 203 and the lifting cylinder 204; the air intake component 24 includes a main air intake pipe 205, a first branch pipe 206 and a second branch pipe 207.

[0047] Specifically, one end of the main intake pipe 205 is connected to an external air source, one end of the first branch pipe 206 and the second branch pipe 207 are both connected to the other end of the main intake pipe 205, the other end of the first branch pipe 206 is connected to multiple lifting cylinders 204 respectively, and the other end of the second branch pipe 207 is connected to the forward and reverse cylinders 203.

[0048] More specifically, when cleaning the aviation fuel sampler 40, the main air intake pipe 205 is connected to an external air source, and air is supplied to the main air intake pipe 205 through the external air source. The first branch pipe 206 delivers gas to the lifting cylinder 204, driving the lifting cylinder 204 to move the lifting linkage base 100. The second branch pipe 207 delivers gas to the forward and reverse cylinder 203, driving the driving end of the forward and reverse cylinder 203 to rotate, thereby driving the cleaning head 201 to rotate, thus achieving complete cleaning of the inner wall of the aviation fuel sampler 40. Furthermore, when operating pneumatically, it also has the advantage of low noise. It should be understood that the external air source can be an air pump, air supply machine, etc., which is not limited in this embodiment.

[0049] It is further understood that the gas in the lifting cylinder 204 and the forward and reverse cylinders 203 can also flow out to the external air source through the first branch pipe 206, the second branch pipe 207 and the main air intake pipe 205, such as when the lifting cylinder 204 rises in the height direction 50 and when the forward and reverse cylinders 203 rotate in the opposite direction.

[0050] More specifically, the first branch pipe 206 includes a main air supply pipe 208 and multiple auxiliary air supply pipes 209. One end of the main air supply pipe 208 is connected to the other end of the main air intake pipe 205. One end of each auxiliary air supply pipe 209 is connected to the other end of the main air supply pipe 208, and the other end is connected to its corresponding lifting cylinder 204.

[0051] Specifically, when the lifting cylinder 204 moves up and down in the height direction 50 to change the position of the base 100, the gas through the main intake pipe 205 enters the main supply pipe 208. Then, the gas in the main supply pipe 208 enters multiple auxiliary supply pipes 209, thereby supplying gas to the multiple lifting cylinders 204. The lifting cylinders 204 drive the base 100 to move along the height direction 50. It should be understood that the number of auxiliary supply pipes 209 can be 2, 3, 5, etc., corresponding to the number of lifting cylinders 204. For example, when there are 2 lifting cylinders 204, the number of auxiliary supply pipes 209 should also be 2.

[0052] Optionally, in one feasible embodiment, both the first branch pipe 206 and the second branch pipe 207 are further provided with a pressure regulating valve 210, which can control the amount of gas entering or flowing out of the lifting cylinder 204 or the forward and reverse cylinder 203, thereby controlling the moving speed of the lifting cylinder 204 and the rotation speed of the forward and reverse cylinder 203, ensuring stability and uniformity in the process of cleaning the inner wall of the aviation fuel sampler 40.

[0053] Furthermore, the structure and arrangement of the cleaning head 201 will be explained in more detail below.

[0054] In one feasible implementation, such as Figure 1 and Figure 2 As shown, the cleaning head 201 includes a connector 211 and a rotating cleaning component 212. One end of the connector 211 is connected to the drive end of the drive member 200, and the other end extends along the height direction 50 and extends into the placement space 11. The rotating cleaning component 212 is fixedly installed on the other end of the connector 211. When cleaning the inner wall of the aviation fuel sampler 40, the drive end of the drive member 200 rotates in conjunction with the connector 211, and the rotation of the connector 211 drives the rotating cleaning component 212 to clean the inner wall of the aviation fuel sampler 40.

[0055] Specifically, in one feasible embodiment, the connector 211 includes a connector 213 and a transmission rod 214. One end of the connector 213 is tractively connected to the drive end of the drive member 200, and the other end is fixedly and detachably connected to one end of the transmission rod 214, such as by snap-fit ​​or riveting. The other end of the transmission rod 214 extends along the height direction 50 through the first through-hole on the first mounting plate 102 into the placement space 11, and the first through-hole is adapted to the transmission rod 214. Furthermore, the rotating cleaning member 212 is configured as a cleaning sponge head 215 fixedly installed on the other end of the transmission rod 214.

[0056] More specifically, the connector 213 and the transmission rod 214 are detachably connected. When it is necessary to replace the cleaning sponge head 215, the transmission rod 214 can be removed from the connector 213, facilitating the replacement of the cleaning sponge head 215. It should be understood that the material used to make the cleaning sponge head 215 should be a highly oil-absorbent and corrosion-resistant material, such as polypropylene or polyurethane; and the shape of the cleaning sponge head 215 is not limited, for example, it can be cylindrical or trapezoidal.

[0057] Furthermore, in one feasible implementation, such as Figure 1 and Figure 2 As shown, since aviation fuel sampler 40 still contains aviation fuel in the cleaning fluid after cleaning, the cleaning device 1 also includes a recovery pipe 30. The first mounting plate 102 is also provided with a second through port that is compatible with the recovery pipe 30. One end of the recovery pipe 30 is connected to an external recovery device, and the other end passes through the second through port and extends into the interior of the aviation fuel sampler 40 placed in the placement space 11, and is close to the bottom wall of the aviation fuel sampler 40.

[0058] Specifically, after the aviation fuel sampler 40 has finished cleaning, the cleaning fluid is recovered to an external recovery device through the recovery pipe 30. The external recovery device then separates the aviation fuel from the cleaning fluid, reducing resource waste. It should be understood that the external recovery device can be an oil separator, etc.

[0059] In summary, the working principle of this aviation fuel sampler 40 is as follows: when cleaning the aviation fuel sampler 40, the second mounting plate 103 is removed, thereby aligning the opening of the aviation fuel sampler 40 with the cleaning head 201, and placing it into the placement space 11 along the height direction 50, and the opening of the aviation fuel sampler 40 abuts against the first mounting plate 102, and then the second mounting plate 103 is installed on multiple connecting rods.

[0060] Further, please see Figure 1 The main intake pipe 205 is connected to an external air source, and air is supplied to the main intake pipe 205 through the external air source. The first branch pipe 206 delivers the gas to the lifting cylinder 204, which drives the lifting cylinder 204 to rise and move the linkage base 100 upward along the height direction 50. The second branch pipe 207 delivers the gas to the forward and reverse cylinder 203, which drives the driving end of the forward and reverse cylinder 203 to rotate and drive the cleaning head 201 to rotate, thereby cleaning the inner wall of the upper part of the inner wall of the aviation fuel sampler 40.

[0061] Furthermore, please see Figure 2 The lifting cylinder 204 discharges gas to an external gas source through the first branch pipe 206, thereby causing the lifting cylinder 204 to descend and the linkage base 100 to move downward along the height direction 50. The drive end of the positive and negative cylinder 203 rotates to drive the cleaning head 201 to rotate, thereby cleaning the inner wall of the lower part of the inner wall of the aviation fuel sampler 40.
