Description

Technical Field

[0001] The utility model relates to the technical field of protection of generator regulating devices, and more particularly to a generator excitation signal regulating device with an anti-damage structure. Background Art

[0002] The generator is connected to the aircraft engine. Due to the large speed variation range in actual aviation applications, the output voltage of the generator is often constantly changing during operation. However, a stable voltage is required when charging aviation batteries. Therefore, the generator regulator was designed. Most generators on the market use ordinary structure regulators such as single-function or multi-function. Their voltage regulation units are mostly electronic regulation units, and there is no information feedback system. Therefore, such regulators have low sensitivity and often cause unnecessary waste. There is no big problem in using them in ordinary commercial aviation fields. However, as passenger aircraft have increasingly higher requirements for driving comfort and fuel consumption, the use of ordinary regulators cannot fully meet the needs.

[0003] The existing patent is an intelligent generator regulator, patent authorization number CN208890691U, which can intelligently control the generator output voltage, reduce vehicle energy consumption, and has high reliability.

[0004] However, during the use of patent authorization number CN208890691U, the regulator is easily damaged by external forces due to the lack of an external protective structure. In order to make the regulator easy to adjust and provide good protection during use, we propose a generator excitation signal adjustment device with an anti-damage structure to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a generator excitation signal adjustment device with an anti-damage structure, which can make the regulator convenient to adjust during use and can also provide good protection effect.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions.

[0007] A generator excitation signal conditioning device with an anti-damage structure includes a signal conditioner, wherein a protective shell is installed on the outer side of the signal conditioner;

[0008] A guide rail is fixedly connected above the opening of the protective shell;

[0009] A first protective door and a second protective door are respectively installed below the guide rail;

[0010] The top of the first protective door is fixedly connected to a first guide sleeve that is slidably connected to the guide rail. The top of the first guide sleeve is fixedly connected to a connecting ear. The surface of the connecting ear is rotatably connected to a connecting shaft. The two ends of the connecting shaft are respectively installed with a first gear and a second gear.

[0011] A first rack meshing with the first gear is installed on the top of the protective shell;

[0012] The top of the second protective door is fixedly connected to a second guide sleeve that is slidably connected to the guide rail, and the top of the second guide sleeve is connected to a second rack that is meshed with the second gear.

[0013] Furthermore, baffles are connected to the inner sides of the first guide sleeve and the second guide sleeve, and the baffles are located on the inner side of the guide rail.

[0014] Furthermore, a guide rod is fixedly connected to the inner side of the guide rail, and the guide rod passes through the baffle.

[0015] Furthermore, springs are sleeved on both ends of the guide rod, one end of the spring is connected to the inner end wall of the guide rail, and the other end of the spring is connected to the baffle.

[0016] Furthermore, buffer pads are bonded to the middle portions of the side walls corresponding to each other of the first protective door and the second protective door.

[0017] Furthermore, a threading hole is provided at the end of the protective shell.

[0018] Furthermore, mounting ears are integrally formed on both side outer walls of the protective shell, and waist holes are symmetrically opened on the surfaces of the mounting ears.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) This solution uses the first protective door and the second protective door in conjunction with the protective shell to protect the signal conditioner. When the signal conditioner needs to be operated, the first protective door is opened to make the first guide sleeve slide in conjunction with the guide rail, and the first gear is matched with the first rack to make the connecting shaft rotate in conjunction with the connecting ear, so that the second gear engages with the second rack to make the second guide sleeve slide in conjunction with the guide rail, and the second protective door moves in the opposite direction relative to the first protective door. The port part of the protective shell is opened, and the signal conditioner can be operated, which can make the conditioner easy to adjust and provide good protection during use.

[0021] (2) In this solution, after the operation of the signal conditioner is completed, the force applied to the first protective door is removed, and the elastic force of the spring is used in conjunction with the baffle to reset the first guide sleeve, so that the first protective door and the second protective door can be closed at the same time, which is very convenient to operate.
