Technical Field

[0001] The utility model relates to the technical field of aircraft auxiliary power devices, in particular to a lubricating oil discharge and diversion device for aircraft auxiliary power devices. Background Art

[0002] At present, the existing oil draining method of the aircraft auxiliary power unit is: remove the oil drain plug at the bottom of the oil tank, place a barrel in front of the oil drain port of the oil tank to receive the lubricating oil, and the lubricating oil is directly discharged into the barrel. After the lubricating oil is discharged into the barrel, a magnetic bar tool with a magnet at the front end is placed into the barrel, and the magnetic force of the magnet is used to adsorb metal chips, thereby judging whether there are metal chips in the lubricating oil. However, since the magnet is cylindrical and is set at the head of the magnetic bar tool, its size and adsorption area are both small, and the adsorption process takes a long time, making it difficult to judge whether the metal chips in the lubricating oil in the barrel are adsorbed cleanly, and the adsorbed metal chips also need to be separated and cleaned from the magnetic bar tool. Utility Model Content

[0003] The utility model aims to provide an aircraft auxiliary power unit lubricating oil discharge diversion device, which can play a good diversion effect on the discharge of lubricating oil and avoid contaminating the ground; at the same time, it can better absorb metal chips in the lubricating oil, making it convenient for the operator to carry out subsequent metal chip cleaning work.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A lubricating oil discharge guide device for an aircraft auxiliary power unit, comprising a guide plate, a rib and a magnetic member, wherein the front side of the guide plate is a side for receiving lubricating oil, and the rib is arranged at the outer edge of the front side of the guide plate; the oil outlet end of the guide plate is formed by the ribs on two opposite sides gradually narrowing toward the middle; the magnetic member is detachably connected to the back side of the guide plate and close to one side of the oil outlet end; the guide plate is obliquely arranged below the oil outlet of the oil tank, and the oil outlet end of the guide plate is the bottom end of the guide plate, and the magnetic member can absorb metal chips in the lubricating oil on the front side of the guide plate.

[0006] As a preferred solution of the utility model, a mounting piece for mounting the magnetic attraction piece is provided on the back side of the guide plate.

[0007] As a preferred embodiment of the present invention, the mounting member includes a first mounting portion and a second mounting portion which are arranged at intervals, and both sides of the magnetic member can be respectively inserted into the first mounting portion and the second mounting portion; a gap is formed between the first mounting portion and the second mounting portion for a person to push out the magnetic member by hand.

[0008] As a preferred solution of the utility model, a filter screen is provided at the oil outlet end of the guide plate.

[0009] As a preferred solution of the present utility model, the inclination angle of the guide plate is 45°.

[0010] As a preferred solution of the utility model, a hook which can be connected to a base beam of the test bench is provided on the back of the guide plate.

[0011] As a preferred solution of the utility model, the oil receiving end of the guide plate extends in a direction away from the oil outlet end to form an anti-overflow portion, and the anti-overflow portion protrudes from the base beam of the test bench.

[0012] As a preferred solution of the present utility model, the guide plate and the retaining edge are integrally injection molded.

[0013] As a preferred solution of the utility model, the guide plate and the retaining edge are both made of acrylic plastic.

[0014] The oil discharge guide device for an aircraft auxiliary power unit provided by the utility model has the following beneficial effects compared with the prior art:

[0015] 1. Before the oil tank is drained, the guide plate is arranged obliquely below the oil outlet of the oil tank. After the oil drain plug of the oil tank is removed, the lubricating oil in the oil tank can be diverted through the guide plate, and the metal chips are attracted by the magnetic suction piece arranged on the back of the guide plate, and finally flow into the receiving piece for receiving the lubricating oil through the oil outlet. During the oil draining process, since the outer edge of the front side of the guide plate is provided with a retaining edge, it can play a blocking role, avoid the phenomenon of contaminating the ground due to the overflow of lubricating oil, and reduce the difficulty and time of cleaning.

[0016] 2. Before the lubricating oil flows into the receiving part for receiving the lubricating oil, the magnetic suction part on the back of the guide plate has already used magnetic force to absorb the metal chips in the lubricating oil to the front of the guide plate, so the operator can quickly know the absorption of the metal chips in the lubricating oil. When the magnetic suction part is removed, the metal chips will no longer be absorbed by the magnetic force, making the subsequent cleaning work more convenient. Furthermore, since the oil outlet end of the guide plate is formed by the opposite two side ribs gradually narrowing to the middle, and the magnetic suction part is arranged on the back of the guide plate near the oil outlet end, the metal chips can be absorbed in a concentrated area, thereby improving the absorption efficiency.

[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. It should be understood that the terms "first", "second", etc. are used in the present utility model to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present utility model, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information.

[0026] like Figures 1 to 4As shown, a preferred embodiment of the utility model provides an aircraft auxiliary power unit oil discharge guide device, which includes a guide plate 1, a retaining edge 11 and a magnetic attraction member (not shown in the figure), the front side of the guide plate 1 is a side for receiving the lubricating oil, and the retaining edge 11 is arranged at the outer edge of the front side of the guide plate 1; the oil outlet end 12 of the guide plate 1 is formed by the retaining edges 11 on two opposite sides gradually narrowing toward the middle; the magnetic attraction member is detachably connected to the back side of the guide plate 1, and close to the oil outlet end 12 side; the guide plate 1 is arranged obliquely below the oil outlet of the oil tank, and the oil outlet end 12 of the guide plate 1 is the bottom end of the guide plate 1, and the magnetic attraction member can adsorb metal chips in the lubricating oil on the front side of the guide plate 1.

[0027] According to the oil discharge guide device of the aircraft auxiliary power unit of the utility model, before the oil tank is drained, the guide plate 1 is arranged obliquely below the oil outlet of the oil tank. After the oil drain plug of the oil tank is removed, the oil in the oil tank can be diverted through the guide plate 1, and the metal chips are adsorbed by the magnetic suction piece arranged on the back of the guide plate 1, and finally flow into the receiving piece for receiving the oil through the oil outlet end 12. In the process of draining the oil, since the outer edge of the front side of the guide plate 1 is provided with a retaining edge 11, it can play a blocking role, avoid the phenomenon of contaminating the ground due to the overflow of the oil, and reduce the difficulty and time of cleaning. In addition, since the magnetic suction piece on the back of the guide plate 1 has used magnetic force to adsorb the metal chips in the oil on the front side of the guide plate 1 before the oil flows into the receiving piece for receiving the oil, the operator can quickly know the adsorption of the metal chips in the oil. When the magnetic suction piece is removed, the metal chips will no longer be adsorbed by the magnetic force, making the subsequent cleaning work more convenient. Furthermore, since the oil outlet end 12 of the guide plate 1 is formed by the two opposite side ribs 11 gradually narrowing toward the middle, and the magnetic attraction member is arranged on the back side of the guide plate 1 close to the oil outlet end 12, the metal chips can be adsorbed in a concentrated area, thereby improving the adsorption efficiency.

[0028] Exemplarily, in order to facilitate the installation and removal of the magnetic member, a mounting member 4 for mounting the magnetic member is provided on the back of the deflector 1. In this embodiment, the mounting member 4 includes a first mounting portion 41 and a second mounting portion 42 arranged at intervals, and the two sides of the magnetic member can be inserted into the first mounting portion 41 and the second mounting portion 42 respectively; a gap 43 is formed between the first mounting portion 41 and the second mounting portion 42 for a person to push out the magnetic member by hand.

[0029] Exemplarily, a filter screen 5 is provided at the oil outlet end 12 of the guide plate 1. Such a design can filter impurities that cannot be adsorbed by the magnetic element, thereby improving the quality of the lubricating oil.

[0030] Exemplarily, in order to ensure a better flow guiding effect, the inclination angle of the flow guide plate 1 is preferably 45°.

[0031] For example, for the convenience of use and fixation, since the oil tank carrying the lubricating oil is usually placed on the test bench, the back of the deflector 1 is provided with a hook 2 that can be connected to the base crossbeam 3 of the test bench. Furthermore, the oil receiving end of the deflector 1 extends away from the oil outlet end 12 to form an anti-overflow portion 13, and the anti-overflow portion 13 protrudes from the base crossbeam 3 of the test bench, so that the lubricating oil can be prevented from dripping into the crossbeam, thereby contaminating the crossbeam, reducing the difficulty and time of cleaning.

[0032] Exemplarily, for the convenience of production, the guide plate 1 and the retaining edge 11 are integrally injection molded; the material of the guide plate 1 and the retaining edge 11 is preferably acrylic plastic with the advantages of being light and resistant to chemical corrosion.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
