Description

Technical Field

[0001] This utility model relates to the field of voltage detection technology, and in particular to a voltage detection warning device. Background Technology

[0002] An electroscope is an instrument used to detect whether an object is charged. Test pens and test sticks are types of electroscopes, used by hand to test for electricity. Currently, there are no devices specifically designed to detect leakage current in puddles near transformers and electrical cabinets after rain. If a person manually uses a test stick, the wet ground after rain poses a risk of electric shock if a leakage is detected. Therefore, designing a leakage detection warning device that can detect leakage current without requiring personnel to approach the detection area is a pressing technical problem. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide an electric voltage detection and warning device to solve the above-mentioned technical problems.

[0005] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution: In some embodiments, the alarm component is a buzzer, or a first LED that emits flashing light, or a combination of a buzzer and a first LED that emits flashing light.

[0006] In some embodiments, a second LED light that is electrically connected to the control circuit board and can emit white light is provided inside the housing.

[0007] In some embodiments, the overall center of gravity of the housing is located at the bottom, and the housing includes a spherical outer shell and a base plate sealed and fixed to the bottom of the outer shell. The outer shell is provided with a plurality of sound-permeable holes, and a waterproof and sound-permeable membrane covering all the sound-permeable holes is attached inside the outer shell.

[0008] In some embodiments, the first conductive component includes a first injection-molded nut connected to the middle of the base plate and a first conductive screw threadedly connected to the first injection-molded nut. The second conductive component includes a ring-shaped conductive ring disposed at the bottom of the base plate, a second injection-molded nut connected to the base plate, and a second conductive screw. The upper end of the second conductive screw passes through a through hole on the conductive ring and is locked to the second injection-molded nut. The first injection-molded nut and the second injection-molded nut are electrically connected to the control circuit board via wires, and the control circuit board is fixed to the top of the base plate by screws.

[0009] In some embodiments, both the first injection nut and the second injection nut are copper injection nuts with blind hole structures.

[0010] In some embodiments, the first conductive screw is connected to a conductive chain.

[0011] In some embodiments, the bottom of the housing is provided with a charging interface electrically connected to the control circuit board, and the sealing cover of the charging interface is provided with a rubber sealing cover.

[0012] In some embodiments, the control circuit board includes a first circuit board and a second circuit board that are arranged vertically and electrically connected, with a bracket between the first circuit board and the second circuit board.

[0013] The technical effects of this utility model are as follows: When using the voltage detection warning device in this solution, pressing the self-test button initiates a self-test. The control circuit board then controls the alarm component to issue an alarm signal, illuminating the second LED. After the self-test is complete, the alarm component stops sounding. Pressing the self-test button again turns off the second LED. The device is then launched into the water area requiring voltage detection. The first and second conductive components, in contact with the water, conduct electrical signals to the control circuit board. The control circuit board receives the feedback voltage and / or current values ​​to determine if there is high voltage in the tested area. If high voltage is present, the control circuit board activates the alarm component, emitting a buzzer and / or flashing lights, thus enabling leakage detection at a considerable distance without requiring... Personnel should approach the testing area to ensure the safety of leakage detection. When using the device's lighting, pressing the self-test button on the bottom of the product will keep the second LED constantly lit, providing long-term illumination. By controlling the overall center of gravity of the casing to be at the bottom, the device ensures that when it is thrown into the testing area, the first and second conductive components are at the bottom and in contact with the water, guaranteeing successful leakage detection. The casing is designed with a sealed and waterproof structure to prevent rainwater from entering and causing damage, thus extending its service life. The first conductive screw connecting to the conductive chain increases conductivity and further lowers the overall center of gravity, ensuring that the first and second conductive components are always at the bottom and in contact with the water when the device is thrown into the water.
