Technical Field

[0001] The utility model relates to the technical field of aviation fuel detection, in particular to a mosquito-proof device for an aviation fuel closed-circuit sampler. Background Art

[0002] The quality of aviation fuel is directly related to the flight safety and performance of an aircraft. Unqualified aviation fuel usually contains excessive impurities, moisture or other pollutants, and these pollutants will damage the engine of the aircraft, resulting in a decline in engine performance or even a malfunction. Therefore, before filling aviation fuel into the aircraft fuel tank, it is necessary to sample and detect the aviation fuel to ensure that the quality of the aviation fuel meets and complies with relevant usage standards, so as to avoid engine failures or other safety hazards caused by aviation fuel quality problems.

[0003] At present, a closed-circuit sampler is usually used to sample and detect aircraft aviation fuel. The closed-circuit sampler is exquisitely designed and mainly composed of key components such as a glass cylinder and a top cover. Its original design intention is to facilitate sampling and ensure the purity of the sample. However, during the use of the closed-circuit sampler, due to the relatively large size of the cylinder mouth of the closed-circuit sampler, mosquitoes are easily flown into the closed-circuit sampler, and the volume of mosquitoes is small, so it is not convenient to clean the mosquitoes. Moreover, during the subsequent sampling process of the closed-circuit sampler, the mosquitoes that have not been cleaned up are likely to contaminate the aviation fuel sample, thereby affecting the accuracy of the detection result. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a mosquito-proof device for an aviation fuel closed-circuit sampler, aiming to solve the problems that the existing closed-circuit sampler is easily contaminated by mosquitoes, is not convenient to clean the mosquitoes, and affects the accuracy of the detection result of the aviation fuel sample.

The mosquito-proof component includes a mounting plate, a mosquito-catching cylinder and a light source arranged in the mosquito-catching cylinder. The mounting plate is mounted at the limiting step. The mosquito-catching cylinder is detachably connected to the mounting plate. A plurality of light-transmitting holes are formed in the cylinder wall of the mosquito-catching cylinder, and all the light-transmitting holes are arranged in a gradually expanding manner along the direction away from the center of the mosquito-catching cylinder. A bottom plate is detachably mounted at the bottom of the mosquito-catching cylinder, and the bottom plate is used to close the inner cavity of the mosquito-catching cylinder.

[0007] Preferably, the number of the mosquito-catching cylinders is multiple, and the multiple mosquito-catching cylinders are symmetrically arranged relative to the center of the mounting plate. Each of the multiple mosquito-catching cylinders includes an upper connecting plate and a lower connecting plate. The upper connecting plate and the lower connecting plate are respectively used for detachably connecting to the mounting plate and the bottom plate. Through holes are formed at positions corresponding to the through holes on the upper connecting plate and the lower connecting plate. Both the upper connecting plate and the lower connecting plate are triangular plates with equal sizes, and any vertex angle of the upper connecting plate and the lower connecting plate is used for abutting against the inner wall of the mosquito-catching cylinder.

[0008] Preferably, docking holes are formed at any vertex angle of the upper connecting plate and the lower connecting plate, and a locking member is inserted through each docking hole to connect the multiple mosquito-catching cylinders in sequence from top to bottom, and the bottom plate is detachably connected to the lowermost lower connecting plate.

[0012] Advantageous effects:

[0013] 1. In the mosquito-proof device for an aviation fuel closed-circuit sampler of the present utility model, when the light source is turned on, mosquitoes can enter the mosquito-catching cylinder through several light-transmitting holes, thereby completing the capture of mosquitoes, effectively preventing mosquitoes from flying into the inner cavity of the closed-circuit sampler and contaminating the aviation fuel sample, and ensuring the accuracy of the detection result of the aviation fuel sample.

[0014] 2. In the mosquito-proof device for an aviation fuel closed-circuit sampler of the present utility model, since several light-transmitting holes are gradually expanded along the direction away from the center of the mosquito-catching cylinder, it can effectively prevent the mosquitoes entering the mosquito-catching cylinder from escaping through the light-transmitting holes, and the use is reliable.

[0015] 3.

[0030] Embodiment 1:

[0031] The present utility model provides a mosquito-proof device for an aviation fuel closed-circuit sampler.

[0032] In an embodiment of the present utility model, a mosquito-proof device for an aviation fuel closed-circuit sampler, the closed-circuit sampler includes a glass cylinder 1, and comprises a housing 2 and a mosquito-proof component. The housing 2 extends into the glass cylinder 1 and is mounted at the mouth of the glass cylinder 1. The housing 2 is hollow, and a limiting step 3 is formed at the top of the housing 2. The mosquito-proof component includes a mounting plate 4, a mosquito-catching cylinder 5 and a light source 6 arranged in the mosquito-catching cylinder 5. The mounting plate 4 is mounted at the limiting step 3. The mosquito-catching cylinder 5 is detachably connected to the mounting plate 4. A plurality of light-transmitting holes 7 are formed in the wall of the mosquito-catching cylinder 5. The plurality of light-transmitting holes 7 are all arranged in a gradually expanding manner along the direction away from the center of the mosquito-catching cylinder 5. A bottom plate 8 is detachably mounted at the bottom of the mosquito-catching cylinder 5, and the bottom plate 8 is used to close the inner cavity of the mosquito-catching cylinder 5.

[0033] Specifically, as Figures 1 to 4 shown, when installing the mosquito-proof device for an aviation fuel closed-circuit sampler of the present utility model, the staff directly extends the housing 2 into the glass cylinder 1 of the closed-circuit sampler, so that the top of the housing 2 is mounted at the mouth of the glass cylinder 1, and the installation and limitation of the present utility model can be completed, and the operation is simple. Further, since a limiting step 3 is formed at the top of the housing 2, the mounting plate 4 in the mosquito-proof component can be directly placed and mounted on the limiting step 3, and the mosquito-catching cylinder 5 is detachably connected to the mounting plate 4. When the closed-circuit sampler does not need mosquito prevention, the staff can directly take out the mounting plate 4 from the housing 2 and synchronously take out the mosquito-catching cylinder 5, so as to meet the use requirements of the closed-circuit sampler in different situations, and the use is flexible and convenient.

[0034] It can be understood that since a light source 6 is arranged in the mosquito-catching cylinder 5, and a plurality of light-transmitting holes 7 are formed in the wall of the mosquito-catching cylinder 5. When the light source 6 is lit, the light of the light source 6 is emitted from the plurality of light-transmitting holes 7. Because mosquitoes are phototactic by themselves, the mosquitoes entering the housing 2 are attracted by the light, and the mosquitoes can enter the mosquito-catching cylinder 5 through the plurality of light-transmitting holes 7, thereby completing the capture of the mosquitoes, effectively preventing mosquitoes from flying into the glass cylinder 1 and contaminating the aviation fuel sample, and ensuring the accuracy of the detection result of the aviation fuel sample. Further, since the plurality of light-transmitting holes 7 are all arranged in a gradually expanding manner along the direction away from the center of the mosquito-catching cylinder 5, that is, the plurality of light-transmitting holes 7 are all trumpet-shaped holes with a small inner diameter and a large outer diameter, which can prevent the mosquitoes entering the mosquito-catching cylinder 5 from escaping through the light-transmitting holes 7, and the use is reliable; at the same time, since the orifice size of the light-transmitting hole 7 close to the center of the mosquito-catching cylinder 5 is small, after the present utility model is used for a long time, the relatively large mosquitoes are easy to block the light-transmitting holes 7, and the mosquito-catching cylinder 5 is detachably connected to the mounting plate 4. By taking out the mounting plate 4, the light-transmitting holes 7 on the mosquito-catching cylinder 5 can be cleaned and dredged, and a bottom plate 8 for closing the inner cavity of the mosquito-catching cylinder 5 is detachably mounted at the bottom of the mosquito-catching cylinder 5. After the staff takes out the mosquito-catching cylinder 5 and removes the bottom plate 8, the mosquitoes can be poured out, so that the mosquito-catching cylinder 5 can be quickly and conveniently cleaned.

[0035] In one embodiment, a through hole 9 is formed in the mounting plate 4 at a position corresponding to the mosquito-catching cylinder 5, and a cover plate 10 for shielding the through hole 9 is hinged at the through hole 9. Specifically, as Figures 1 to 4 shown, by forming the through hole 9 in the mounting plate 4 at a position corresponding to the mosquito-catching cylinder 5, the mosquito-catching cylinder 5 can communicate with the outside. When the light source 6 needs to be replaced, the staff can directly take out the light source 6 from the mosquito-catching cylinder 5 through the through hole 9 and replace the light source 6, which is convenient to operate. Further, since the cover plate 10 is hinged at the through hole 9, the through hole 9 can be closed and shielded by the cover plate 10, thereby preventing mosquitoes flying into the mosquito-catching cylinder 5 during the use of the present utility model from escaping through the through hole 9, and the use is reliable.

[0036] In one embodiment, the number of the mosquito-catching cylinders 5 is multiple, and the multiple mosquito-catching cylinders 5 are symmetrically arranged relative to the center of the mounting plate 4. The multiple mosquito-catching cylinders 5 all include an upper connecting plate 11 and a lower connecting plate 12. The upper connecting plate 11 and the lower connecting plate 12 are respectively used for detachably connecting with the mounting plate 4 and the bottom plate 8. Through holes 13 are formed in the upper connecting plate 11 and the lower connecting plate 12 at positions corresponding to the through hole 9. The upper connecting plate 11 and the lower connecting plate 12 are both triangular plates with equal sizes, and any vertex angle of the upper connecting plate 11 and the lower connecting plate 12 is used for abutting against the inner wall of the mosquito-catching cylinder 5.

[0037] Specifically, as Figures 1 to 4 shown, since the number of the mosquito-catching cylinders 5 is multiple and the multiple mosquito-catching cylinders 5 are symmetrically arranged relative to the center of the mounting plate 4, not only can the mosquito-catching amount of the present utility model be increased, but also the mounting plate 4 is uniformly stressed and the structural design layout is reasonable. Further, since the upper connecting plate 11 and the lower connecting plate 12 of the mosquito-catching cylinder 5 are respectively used for detachably connecting with the mounting plate 4 and the bottom plate 8, the whole mosquito-catching cylinder 5 can be disassembled and assembled with the mounting plate 4 and the bottom plate 8, which is beneficial to the replacement, maintenance and cleaning of the mosquito-catching cylinder 5. At the same time, by forming the through holes 13 in the upper connecting plate 11 and the lower connecting plate 12 at positions corresponding to the through hole 9, the light source 6 can be completely received in the mosquito-catching cylinder 5, and the structural design is simple and reasonable. It can be understood that since the upper connecting plate 11 and the lower connecting plate 12 are both triangular plates with equal sizes and any vertex angle of the upper connecting plate 11 and the lower connecting plate 12 is used for abutting against the inner wall of the mosquito-catching cylinder 5, the radial limit in the horizontal plane of the mounting plate 4 and the mosquito-catching cylinder 5 can be realized, and the mounting stability of the mosquito-catching cylinder 5 is improved.

[0038] In another embodiment, docking holes 14 are formed at any vertex angle of the upper connecting plate 11 and the lower connecting plate 12, and locking members 15 are respectively inserted into any docking hole 14 to connect the multiple mosquito-catching cylinders 5 in sequence from top to bottom, and the bottom plate 8 is detachably connected with the lowermost lower connecting plate 12. It can be understood that, as Figure 3 and Figure 4As shown, multiple mosquito traps 5 can also be connected in an upper and lower stacked manner, thereby further increasing the mosquito capture capacity of the present utility model. Further, the locking member 15 is preferably a bolt connection in the prior art, which is easy to obtain materials and convenient for disassembly and assembly. The staff can detachably connect the upper connecting plate 11 of the mosquito trap 5 located above to the mounting plate 4 through the locking member 15. At the same time, the lower connecting plate 12 is detachably connected to the upper connecting plate 11 of the mosquito trap 5 located below through the locking member 15. Thus, multiple mosquito traps 5 can be sequentially connected from top to bottom. The structural design is simple and reasonable, and it is conducive to the disassembly, replacement, cleaning and maintenance of the mosquito trap 5. In addition, since docking holes 14 are provided at any vertex of the upper connecting plate 11 and the lower connecting plate 12, and a locking member 15 is inserted through any docking hole 14, any mosquito trap 5 can be installed and fixed at multiple points, improving the overall structural strength of the mosquito prevention assembly.

[0039] In one embodiment, a circular flange 16 is formed on the outer wall of the top of the outer shell 2, and the circular flange 16 is used to abut against the top surface of the glass cylinder 1. Specifically, as Figure 1 shown, the axial limit of the outer shell 2 can be achieved by abutting the circular flange 16 against the top surface of the glass cylinder 1; at the same time, in the actual production and manufacturing process of the present utility model, the outer wall size of the outer shell 2 should be equal to or smaller than the inner wall size of the glass cylinder 1. Preferably, the outer shell 2 and the glass cylinder 1 are in interference fit, so as to achieve the radial limit of the outer shell 2 and ensure the installation stability of the outer shell 2. The structural design is compact and reasonable.

[0040] In one embodiment, as Figure 1 and Figure 3 shown, a screen 17 is detachably installed at the bottom of the outer shell 2, which can further prevent mosquitoes from passing through the outer shell 2 and flying into the glass cylinder 1, improving the use reliability of the present utility model.

[0041] In one embodiment, the light source 6 is a rechargeable light source 6. It can be understood that the rechargeable light source 6 usually has a long battery life, so as to continuously provide the light source 6 for the mosquito trap 5 and ensure the efficient operation of the present utility model; at the same time, the user can connect the light source 6 to an external power source through a charging cable for charging, without the need to purchase additional batteries, saving the use cost and being more convenient to use.

[0042] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
