Description

Technical Field

[0001] This utility model relates to the technical field of aviation battery voltage detection devices, and in particular to an auxiliary detection device for the voltage of a single airborne battery cell. Background Technology

[0002] Airborne batteries are a very important airborne component of aircraft. During flight, when the main power source and other auxiliary power sources fail, the airborne batteries are relied upon to supply power to the important equipment on the aircraft in order to maintain the aircraft's flight to the nearest airport for landing. Therefore, there are strict maintenance standards for airborne batteries.

[0003] According to the process requirements for airborne batteries, regular charge-discharge maintenance is necessary. During this maintenance, the individual cell voltage is a crucial indicator and must be measured periodically. Currently, the individual cell voltage is measured manually using a multimeter. This method is time-consuming and labor-intensive. Furthermore, because the airborne battery casing is made of metal, improper operation can easily lead to short circuits in individual cells, causing damage to both the operator and the battery. Utility Model Content

[0004] The technical problem solved by this utility model is to provide an auxiliary detection device for the voltage of an airborne battery cell, so as to solve the problems in the background art mentioned above.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] An auxiliary detection device for the voltage of individual airborne battery cells includes a housing, a buckle, a retractable probe, a diode indicator light, a measurement line plug, and a partition. The outer wall of the housing is equipped with a buckle for securing the housing to the airborne battery casing. The housing contains a partition, and retractable probes for connecting to the voltage measurement pins of the individual airborne battery cells are respectively installed on the partition and the upper part of the inner wall of the housing. A support platform is located at the front end of the housing, and a diode indicator light is mounted on the platform. The diode indicator light is connected to the retractable probe. One end of the measurement line plug is connected to the retractable probe via a detection line, and the other end of the measurement line plug is connected to the airborne battery measurement line.

[0007] In this invention, retractable probes are respectively provided on both sides of the partition, and the retractable probes are arranged symmetrically. The retractable probes provided on the upper part of the inner wall of the box are also arranged symmetrically.

[0008] In this invention, to facilitate the observation and adjustment of the liquid level of each airborne battery cell during maintenance, a detection line connected to a retractable probe on the separator is arranged along the longitudinal center line of the separator, and a detection line connected to a retractable probe on the upper part of the inner wall of the battery box is arranged along the inner wall of the battery box. This ensures that the vent holes of the airborne battery cells are visible, making it convenient to observe the liquid level of each airborne battery cell during maintenance.

[0009] Beneficial effects: This utility model can reduce the number of maintenance personnel and workload, avoid short circuits caused by improper operation during manual measurement of individual unit voltage, and effectively improve the safety margin of production. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0015] See Figures 1-4An auxiliary detection device for the voltage of individual airborne battery cells includes a housing 1, clips 2, retractable probes 3, diode indicator lights 4, measurement cable plugs 5, and a partition 6. Clips 2 are symmetrically arranged on both sides of the outer wall of the housing 1 to secure the housing 1 to the airborne battery casing, preventing loose connections at the acquisition terminals and ensuring that the device will not experience poor contact due to equipment vibration during operation. A partition is provided inside the housing 1, and the retractable probes 3 are located on both sides of the partition 6 and on the upper part of the inner wall of the housing 1 for connecting to the voltage measurement pins of the individual airborne battery cells. The use of retractable probes ensures accurate connection. The reliability of the contact is ensured; a support platform is provided at the front end of the housing 1, and a diode indicator light 4 is provided on the support platform. The diode indicator light 4 is connected to the retractable probe 3. When the retractable probe 3 has good contact with the voltage of the airborne battery cell, the yellow LED lights up; when the voltage of the airborne battery cell reaches the normal operating voltage, the green LED lights up. The yellow and green LEDs are used to determine whether the retractable probe 3 has good contact with the airborne battery cell and the voltage range of the airborne battery cell. One end of the measuring line plug 5 is connected to the retractable probe 3 through a detection line, and the other end of the measuring line plug 5 is connected to the airborne battery measuring line.

[0016] In this embodiment, the retractable probes 3 on both sides of the partition 6 are arranged symmetrically, and the retractable probes 3 on the upper part of the inner wall of the housing 1 are also arranged symmetrically. In order to facilitate the observation and adjustment of the liquid level of the airborne battery cells during the maintenance of the airborne battery, the detection line connected to the retractable probes 3 on the partition 6 is arranged along the longitudinal center line of the partition 6, and the detection line connected to the retractable probes 3 on the upper part of the inner wall of the housing 1 is arranged along the inner wall of the housing 1, so as to ensure that the vent hole of the airborne battery cell can be exposed, and the liquid level of the airborne battery cell can be observed during the maintenance process.

[0017] In this embodiment, when the retractable probe 3 makes good contact with the airborne battery cell, the diode indicator light 4 lights up; when the contact is poor, the diode indicator light 4 does not light up. Furthermore, the yellow and green colors can help maintenance personnel to roughly observe the range of the airborne battery cell voltage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
