AI Technical Summary

Technical Problem

During flight, the existing oil extraction device has only one notch in the oil suction head, which is easily attached to the inner wall of the fuel tank through the flexible swing of the bellows, affecting the smoothness of oil extraction.

Method used

A new type of rocker arm oil extractor is designed. The oil suction head is provided with multiple oil suction ports distributed in a circumferential array and flexibly connected to the pipe joint through a bellows. The distribution of multiple oil suction ports ensures that when one oil suction port is close to the inner wall of the oil tank, the other oil suction ports can still absorb oil smoothly. The flange structure or clamp is used to achieve detachable, fixed and sealed docking.

Benefits of technology

This ensures smooth oil extraction during flight, avoids blockage caused by a single oil suction port being close to the inner wall of the fuel tank, and improves the stability of oil delivery.

Description

Technical Field

[0001] This utility model relates to a novel rocker arm oil extractor, belonging to the technical field of oil extractor technology. Background Technology

[0002] The aircraft's fuel system requires fuel to be drawn from the fuel tank via a fuel extractor. Existing fuel extractors, in order to accommodate the swaying motion during flight, use a corrugated pipe to connect the fuel suction head and the pipe fitting (see Chinese Patent Publication No. CN212406898U). During flight, the fuel suction head with only one notch can easily stick to the inner wall of the fuel tank due to the flexible swaying motion of the corrugated pipe, affecting the smooth flow of fuel extraction. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel rocker arm oil extractor.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides a novel rocker arm oil extractor, comprising:

[0006] Oil suction head A has multiple oil suction ports arranged in a circumferential array at intervals.

[0007] It also includes a pipe fitting for docking with the aircraft's fuel system pipeline, and the suction head A can be flexibly connected to the pipe fitting via the bellows A.

[0008] The pipe fitting is fixed with a mounting platform, and the mounting platform contains an O-ring that provides a seal when it is in close contact with the oil tank.

[0009] The corrugated pipe A and the rear end of the pipe joint can be detachably and securely connected via a flange structure or clamp.

[0010] The corrugated pipe A and the oil suction head A can be detachably and securely connected via a flange structure or clamp.

[0011] It also includes the pipe joint in front of the bellows A or the bellows B which is connected to the bellows A in a sealed manner.

[0012] The end of the corrugated pipe B is sealed and connected to an oil suction head B, which has multiple oil suction ports B arranged in a circumferential array at intervals.

[0013] The corrugated pipe B and the oil suction head B can be detachably and securely connected via a flange structure or clamp.

[0014] The beneficial effects of this utility model are as follows: the oil suction head A has multiple oil suction ports distributed in a circumferential array at intervals. During flight, after any one of the oil suction ports is pressed against the inner wall of the fuel tank, the other oil suction ports can ensure that the fuel can enter smoothly and be delivered to the pipe joint without being obstructed, thus ensuring the smooth flow of oil intake. This solves the problem that the oil suction head with only one notch in the prior art is prone to pressing against the inner wall of the fuel tank through the flexible swing of the corrugated pipe, which affects the smooth flow of oil intake. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model;

[0016] Figure 2 This is a schematic front sectional view of the present invention;

[0017] In the diagram: 1-pipe fitting; 11-mounting platform; 2-O-ring seal; 3-bellows A; 4-oil suction head A; 41-oil suction port; 5-bellows B; 6-oil suction head B; 61-oil suction port B. Detailed Implementation

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figures 1 to 2 As shown.

[0020] This application discloses a novel rocker arm oil extractor, comprising:

[0021] A pipe fitting 1 is used to connect with the fuel system pipeline of an aircraft. A mounting platform 11 is integrally fixed on the pipe fitting 1. An O-ring 2 is inside the mounting platform 11. When the mounting platform 11 is in close contact with the fuel tank, the O-ring 2 provides a seal.

[0022] The rear end of the pipe connector 1 is fixedly and sealedly connected to a bellows A3. The bellows A3 and the rear end of the pipe connector 1 can be detachably and securely connected via a flange structure or clamp. The end of the bellows A3 is sealedly connected to an oil suction head A4. The oil suction head A4 has multiple circumferentially arrayed oil suction ports 41, which can achieve multi-directional oil suction. The bellows A3 and the oil suction head A4 can be detachably and securely connected via a flange structure or clamp. The oil suction head A4 can flexibly oscillate via the bellows A3.

[0023] The pipe joint 1 in front of the bellows A3, or the bellows A3 itself, is fixedly and sealed to the bellows B5 by bonding or integral molding. The end of the bellows B5 is sealed to an oil suction head B6, which has multiple circumferentially arrayed oil suction ports B61, allowing for multi-directional oil suction. The bellows B5 and the oil suction head B6 can be detachably and sealed together via a flange structure or clamps. The oil suction head B6 can flexibly swing through the bellows B5. The bellows B5 and bellows A3 correspondingly form the swing arms of the oil suction heads A4 and B6.

[0024] Because the fuel intake head A4 has multiple circumferentially spaced fuel intake ports 41, and the fuel intake head B6 has multiple circumferentially spaced fuel intake ports B61, during flight, if any one of the fuel intake ports 41 or B61 is pressed against the inner wall of the fuel tank, the other fuel intake ports 41 or B61 can ensure that the fuel enters smoothly and is delivered to the pipe joint 1 without obstruction, thus ensuring smooth fuel intake. This solves the problem that in the prior art, the fuel intake head with only one notch can easily press against the inner wall of the fuel tank through the flexible swing of the corrugated pipe, affecting the smooth intake of fuel.
