Technical Field
[0001] An auditory alarm testing device for an electroscope belongs to the field of electroscope testing technology. Background Technology
[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 audible alarm of a voltage detector after contact with a live 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 on the clarity and distinguishability of the audible indication of a voltage detector. Therefore, designing a technical solution that can test the sound of a voltage detector alarm has become an urgent problem to be solved in this field. Utility Model Content

One end of the slide rail is fixed to the fixed frame by a fixed seat, and the other end extends to the surface of the slide rail bracket and is locked in the clip on the surface of the slide rail bracket.
[0007] Preferably, the height adjustment component is vertically mounted on the support rod on the slide rail surface, the support rod is a telescopic rod, and the fixing mechanism is mounted on the top of the support rod.

[0014] Figure 3 for Figure 2 Top view.
[0015] The components include: 1. Fixing frame; 2. Test plate; 3. Test hole; 4. Sound level meter; 5. Test bracket; 6. Fixing base; 7. Slide rail; 8. Slide rail bracket; 9. Electrical appliance to be tested; 10. Support rod; 11. Fixing sleeve. Detailed Implementation
[0016] Figures 1-3 This 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.
[0017] like Figures 1-3 As shown, an auditory alarm testing device for an electroscope includes a mounting frame 1, a test plate 2 vertically mounted on the top of the mounting frame 1, and a plurality of test holes 3 formed on the test plate 2. The test holes 3 include a central hole located at the center, and multiple sets of test holes 3 arranged around the central hole. Each set of test holes 3 around the central hole includes multiple test holes evenly arranged on the same circumference.
[0018] A test bracket 5 is placed vertically on the back side of the test plate 2. A sound level meter 4 is installed on the upper end of the test bracket 5. The sound level meter 4 passes through any one of the test holes 3 on the surface of the test plate 2 and extends to the front side of the test plate 2.
[0019] A slide rail 7 is installed at the center of the bottom of the fixed frame 1, and the slide rail 7 is perpendicular to the base of the fixed frame 1. A set of slide rail brackets 8 are arranged side by side at the front end of the base of the fixed frame 1. A fixing seat 6 is also installed in the base of the fixed frame 1. One end of the slide rail 7 is inserted into the fixing seat 6 in the base of the fixed frame 1 and is fixed to the fixed frame 1 by the fixing seat 6. The other side of the slide rail 7 extends towards the slide rail bracket 8. Two locking blocks are installed opposite each other on the surfaces of the two slide rail brackets 8. The slide rail 7 is locked onto the surfaces of the two slide rail brackets 8 by the locking blocks on the surfaces of the slide rail brackets 8.
[0020] Two support rods 10 are vertically installed on the surface of the slide rail 7. The two support rods 10 are arranged along the extension direction of the slide rail 7 and are slidably installed on the surface of the slide rail 7. The top of the two support rods 10 is a two-section sleeve structure, that is, one section of the rod is coaxially embedded in the outer cylinder, thus making the support rod 10 a height-adjustable telescopic structure.
[0021] A fixing sleeve 11 is fixed to the top of each of the two support rods 10, which are embedded in the top of the rod body. A locking bolt is radially installed on the surface of the fixing sleeve 11. The electrical appliance 9 to be tested is installed directly above the slide rail 7 through the two fixing sleeves 11 and locked in place by the fixing sleeves 11. After locking, the test part of the electrical appliance 9 to be tested faces away from the test plate 2.
[0022] The specific working process and working principle are as follows: Adjust the position, height and spacing of the two support rods 10 according to the electrical appliance 9 to be tested, then put the electrical appliance 9 to be tested into the fixing sleeve 11 at the top of the support rod 10 and lock it. At this time, the test part of the electrical appliance 9 to be tested faces away from the test plate 2.
[0023] Then, according to the test requirements, the sound level meter 4 is passed through any one of the test holes 3. After the test begins, the sound level meter 4 is turned on, and high voltage is applied to the detection part of the electrical appliance 9 to be tested to trigger it. After the electrical appliance 9 to be tested is triggered, it will sound an alarm. At this time, the audibility of the sound signal emitted by the electrical appliance 9 to be tested through the sound level meter 4 is evaluated according to the test requirements in the industry standard.
[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. 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.
