Description

Circuit testing device for energy storage container Technical Field The utility model relates to a line testing device for an energy storage container, and belongs to the technical field of circuit conduction. Background In the installation, overhaul and daily maintenance work of an electric circuit, a buzzer of a common digital multimeter is used as a common function for rapidly judging the circuit conductivity, and a plurality of technical defects to be improved are urgent in the practical application process. Firstly, the acoustic prompt mechanism of the buzzer is remarkably reduced in reliability in a complex operation environment. When an operator is in a place with noise intensity exceeding 75dB, such as a mechanical operation workshop, a transportation junction or a construction site, the sounding volume of the conventional buzzer of about 60dB is easily covered by environmental noise, so that a tester can confirm a test result by repeatedly observing a display screen or being close to a universal meter body. The failure of the auditory feedback reduces the detection efficiency, and potential safety hazards are more easily caused by response delay in the scene of severe requirements on the timeliness of operation such as a high-voltage power distribution system. Meanwhile, the acoustic signals cannot form effective warning records, so that information synchronization during collaborative operation of multiple people is not facilitated. Secondly, the visibility defect of the traditional buzzer in a low-illumination environment severely restricts the operation precision. When testing is performed at night construction sites, closed equipment cabins or places with insufficient illumination conditions such as underground pipeline wells, an operator needs to hold two meter pens to accurately position test points and synchronously observe a display interface of a universal meter body, and the visual distraction is extremely easy to cause false touch or poor contact of probes. Particularly, when detecting densely arranged wiring terminals or miniature electronic elements, the physical dimensions of conventional watches and the low contrast display characteristics of a monochromatic liquid crystal screen lead operators to frequently adjust the body posture to obtain an optimal observation angle, and occupational muscle strain is easily caused by long-term accumulation of the unnatural operation posture. In addition, in the special environment with metal reflection or electromagnetic interference, misreading risks are easily generated by simply relying on visual judgment. Furthermore, the physical limitations of standard stylus line length severely affect the continuity of the inspection operation. Taking the international standard shipping container as an example, the internal length of the container generally reaches 12 meters, and a multi-layer wire slot structure exists, when the diagonal position or the conducting state of an upper layer circuit and a lower layer circuit are required to be detected, the original meter pen line length of 1.2 meters often forces operators to take the flexible measures such as sectional test, temporary wiring or mobile detection equipment. This mode of operation not only significantly increases the time cost of a single test, but also is more likely to introduce measurement errors due to the temporary contact impedance. In large industrial facilities such as automatic stereoscopic warehouse, wind power generation cabin, etc., the line length is insufficient and can also lead to the detection personnel to need frequent climbing and movement, both has high altitude construction risk, is difficult to guarantee the synchronism between the test point again. Disclosure of Invention The utility model aims to solve the technical problems, and provides a circuit testing device for an energy storage container, which adopts a pen type structure to conduct test, selects a testing line with a corresponding length according to a testing distance, and is provided with a lighting component and a vibration motor to confirm testing results in different environments. The technical scheme is that the circuit testing device for the energy storage container comprises a shell, a printed circuit board, a testing needle and a testing wire, wherein the printed circuit board, the testing needle and the testing wire are arranged in the shell, one end of the testing needle is connected with a ground wire of the printed circuit board, the other end of the testing needle is contacted with a first testing point, one end of the testing wire is connected with a testing input end of the printed circuit board, the other end of the testing wire is contacted with a second testing point, a VCC power end ground connected with the anode and cathode of a battery, a testing assembly, a triode and a vibrating motor are further arranged on the printed circuit board, the testing assembly, the triode and the vibrating m
