[0002] An electroscope is an instrument used to detect whether an object is charged and to roughly estimate the amount of charge. An electroscope generally consists of three main parts: a detection part, an insulation part, and a handle part. To improve the safety of operators, electroscopes with audible and visual alarm functions are common in existing technologies, such as the Chinese utility model patent with application number 202220159225.1 (application date January 21, 2022) entitled "An Audible and Visual High-Voltage Electroscope for Power Maintenance," and the Chinese utility model patent with application number 202122964351.2 (application date November 29, 2021) entitled "Electrical Detector." Therefore, the intensity of the light emitted by a voltage detector after contact with a charged object has become an important performance indicator of the voltage detector, and it also directly affects the personal safety of the staff. The industry standard document DL / T 740-2014 has made corresponding provisions for the clarity and distinguishability of the visual indication of the voltage detector. Therefore, designing a technical solution that can test the light intensity of the voltage detector when it is alarming has become an urgent problem to be solved in this field. Utility Model Content

[0019] Figures 1-3This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.

[0020] like Figures 1-3 As shown, a visual alarm testing device for an electroscope includes an observation bracket 14 and a reflective bracket 5 arranged opposite to each other. Pullers are respectively installed at the four corners of the bottom of the observation bracket 14 and the reflective bracket 5. An observation plate 1 is vertically fixed to the upper part of the observation bracket 14, and a reflective plate 6 is vertically fixed to the upper part of the reflective bracket 5. The surfaces of the observation plate 1 and the reflective plate 6 are arranged opposite to each other.

[0021] An extension frame is provided at the bottom between the observation bracket 14 and the reflector bracket 5, extending from the reflector bracket 5 toward the observation bracket 14. The extension frame includes a central extension frame 7 and side extension frames 8 located on both sides of the central extension frame 7. The central extension frame 7 extends from the middle of the end of the reflector bracket 5 toward the observation bracket 14 toward the observation bracket 14. The two side extension frames 8 extend radially toward both sides of the observation bracket 14 from both ends of the end of the reflector bracket 5 toward the observation bracket 14. The central extension frame 7 and the two side extension frames 8 are connected by a reinforcing rod 9, and feet are provided at the bottom of both ends of the reinforcing rod 9 to keep the extension frame in a horizontal position.

[0022] A test slide rail 13 is mounted on the surface of the central extension frame 7. One end of the test slide rail 13 is fixed to the surface of the central extension frame 7, and the other end extends to the top of the bottom of the observation bracket 14 and is fixed to the observation bracket 14. A light source slide rail 11 is also mounted on the surface of the side extension frames 8 on both sides of the central extension frame 7.

[0023] Two fixing brackets 3 are vertically arranged between the observation bracket 14 and the reflector bracket 5. One fixing bracket 3 is fixed to the surface of the middle extension bracket 7, and the other fixing bracket 3 is slidably installed on the surface of the slide rail 13 to be tested. Fixing sleeves 2 are respectively installed on the top of the two fixing brackets 3. The electrical appliance 4 to be tested passes through the middle of the fixing sleeves 2 on both sides and is fixed to the top of the two fixing brackets 3 through the fixing sleeves 2 on both sides. A through hole is opened in the middle of the reflector plate 6. After the electrical appliance 4 to be tested is fixed, its end detection part passes through the through hole and extends to the back side of the reflector plate 6.

[0024] A light source frame 10 is vertically mounted on the surface of the light source slide rails 11 on both sides, and the light source frames 10 on both sides are also slidably mounted on the surface of the corresponding light source slide rails 11. A light source 12 is mounted on the top of each of the two light source frames 10. The light sources 12 on both sides are tilted according to the arrangement direction of the side extension frame 8, and the light source emitting end of the light source 12 on both sides is directly opposite the through hole in the middle of the reflector 6.

[0025] The specific working process and working principle are as follows: Adjust the distance between the two mounting brackets 3 according to the length of the electrical appliance 4 to be tested, and install the electrical appliance 4 into the mounting sleeves 2 at the top of the two mounting brackets 3, and lock it in place using the locking bolts radially installed in the mounting sleeves 2. After the electrical appliance 4 is locked, the detection part at its end passes through the through hole on the surface of the reflector 6 and extends to the back side of the reflector 6. Then adjust the position of the light source brackets 10 on both sides so that the light emitted by the light source 12 at the top of the light source brackets 10 on both sides can be directly aligned with the through hole in the middle of the reflector 6.

[0026] After the test begins, turn on the light source 12 and simultaneously apply high voltage from the back of the reflector 6 to the detection part of the electrical appliance 4 to be tested to trigger it. After the electrical appliance 4 is triggered, it will emit a light alarm. At this time, observe the alarm light emitted by the electrical appliance 4 to be tested on the surface of the observation board 1 according to the testing requirements in the industry standard, and determine the clarity and discernibility of the electrical appliance 4 to be tested.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
