Description
Technical Field
[0001] This utility model relates to the field of power safety technology, and in particular to an electric shock warning device. Background Technology
[0002] Ensuring the safety of operators in power systems and providing early warnings and alerts when they are in dangerous situations have become key concerns for society, especially in the high-voltage power sector. High-voltage transmission lines are prone to sudden arcing when people approach, causing instantaneous electric shocks without their knowledge and endangering their lives. Existing electric shock warning devices on the market are bulky, have low sensitivity, and their band switches cannot function as power switches, requiring a separate power switch.
[0003] A search revealed that prior art CN204791428U discloses an electric shock warning device, comprising a housing and an inductive antenna. The inductive antenna extends outside the housing. The housing houses a filtering and signal preprocessing module, an ASIC chip for electric field signal detection and analysis, a microcontroller, a band switch, a buzzer alarm module, and a power supply module. The inductive antenna is connected to the signal input terminal of the filtering and signal preprocessing module. The signal output terminal of the filtering and signal preprocessing module is connected to the input terminal of the ASIC chip for electric field signal detection and analysis. The output terminals of the ASIC chip and the band switch are respectively connected to the signal input terminal of the microcontroller. The signal output terminal of the microcontroller is connected to the input terminal of the buzzer alarm module. This utility model is an electric shock warning device that emits a "beeping" sound when a person approaches a power line and the electric field strength reaches a warning value, indicating a danger of electricity and warning them not to approach.
[0004] Although existing technologies can serve as safety warnings, the wearing method of current electric shock warning devices is relatively fixed and lacks flexibility. They cannot freely switch between wearing clothing and wearing a safety helmet, which is inconvenient to use. Utility Model Content
[0005] The purpose of this utility model is to provide an electric shock warning device, which aims to solve the problems of existing electric shock warning devices having a relatively fixed wearing method, poor flexibility, and inability to freely switch between wearing clothing and wearing a safety helmet, making them inconvenient to use.
[0006] To achieve the above objectives, this utility model provides an electric shock warning device, including a housing, a control module and a power module disposed inside the housing, the power module being electrically connected to the control module, and an auxiliary mechanism;
[0007] The auxiliary mechanism includes a horn, microphone, helmet buckle, back clip, mounting base, rigid plastic block, T-shaped block, hexagonal column, battery, limiting plate, and operating device. A panel is provided on the front of the housing, and the helmet buckle is mounted on the rear. The back clip is rotatably mounted on one side of the helmet buckle via a pivot and a spring. The horn is detachably connected to the housing and electrically connected to the control module. The microphone is detachably connected to the housing and electrically connected to the control module, and is located at the bottom inside the housing. The mounting base is detachably connected to the housing. The T-shaped blocks are integrally formed on both sides of the rigid plastic block and are located on the rear inner side wall of the outer casing. The T-shaped blocks are slidably connected to the mounting base. The outer casing of the battery is slidably snapped onto the rigid plastic block and electrically connected to the power module. The hexagonal columns are detachably connected to the mounting base and are symmetrically arranged in four positions. A threaded limit rod is provided at the top for limiting. The limit plate is bolted to the hexagonal columns and abuts against the front side of the battery casing. The operating device is electrically connected to the control module and is located on both sides of the top of the outer casing.
[0008] The outer casing has a sound-passing part and a corresponding mating hole on one side.
[0009] The control module includes a PCB board and an adjustment switch. The PCB board is detachably connected to the housing and electrically connected to the power module, and is located inside the housing. The adjustment switch is located on the PCB board.
[0010] The power module is provided with an earphone jack and a charging port. The earphone jack is located on the power module and is electrically connected to the control module. The charging port is located on the power module and is used for charging the battery.
[0011] The operating device includes a calibration button and a power button. The calibration button is electrically connected to the control module and is located on the top left side of the housing. The power button is electrically connected to the power module and is located on the top right side of the housing.
[0012] This utility model discloses an electric shock warning device. During use, a control module and a power module work together. When a person reaches a certain voltage field level, the induction antenna on the control module senses the voltage field and collects the strength signal. This information is then transmitted to a filtering and signal preprocessing module for filtering and selection. The filtering and preprocessing module then transmits the filtered useful information to an ASIC chip for electric field signal detection and analysis. The analysis results are then transmitted to a microcontroller. The microcontroller compares the results with its internal database of voltage field strength fluctuation ranges and distance fine-tuning. If the voltage exceeds the safe range, the microcontroller activates an alarm module and sounds an alarm. The device can be directly plugged into the safety helmet's connector using a safety helmet buckle. The safety helmet buckle and back clip work together to form a clip structure, facilitating the installation of the device on work attire. This solves the problems of existing electric shock warning devices having a fixed wearing method, poor flexibility, and inconvenience in switching between clothing and safety helmet wearing methods.

[0020] In this embodiment, a control module 102 and a power module 103 are provided inside the housing 101, and the power module 103 is electrically connected to the control module 102.
[0021] The outer shell 101 has a panel 104 on its front side and a helmet buckle 107 on its rear side. A back clip 108 is rotatably mounted on one side of the helmet buckle 107 via a pivot and a spring. A speaker 105 is detachably connected to the outer shell 101 and electrically connected to the control module 102. A microphone 106 is detachably connected to the outer shell 101 and electrically connected to the control module 102, and is located at the bottom inner side of the outer shell 101. A mounting base 109 is detachably connected to the outer shell 101 and is located on the inner rear wall of the outer shell 101. The rigid plastic block 11... The T-shaped blocks 111 are integrally arranged on both sides. The T-shaped blocks 111 are slidably connected to the mounting base 109. The outer shell of the battery 113 is slidably snapped onto the rigid plastic block 110 and electrically connected to the power module 103. The hexagonal columns 112 are detachably connected to the mounting base 109 and four are symmetrically arranged. A threaded limit rod is provided at the top for limiting. The limit plate 114 is bolted to the hexagonal columns 112 and abuts against the front side of the outer shell of the battery 113. The operating device is electrically connected to the control module 102 and is arranged on both sides of the top of the outer shell 101. The panel 104 is fixed with bolts for the protection of internal working components. The safety helmet buckle 107 is fixed with bolts and rotates on one side via a pivot and a spring to mount the back clip 108, thus forming a clip structure. The speaker 105 and the microphone 106 are fixed inside the housing 101 with bolts. The mounting base 109 is fixed with countersunk bolts. The mounting base 109 has symmetrically arranged T-shaped grooves to facilitate the sliding installation of the T-shaped block 111. The T-shaped block 111 is integrally and symmetrically arranged on the rigid plastic block 110 for guidance during installation. The battery 113 is rechargeable. The lithium battery casing is slidably snapped into the cavity of the rigid plastic block 110. Then, a hexagonal groove is provided on the mounting base 109 to facilitate the installation of the hexagonal post 112. The top of the hexagonal post 112 is provided with a threaded hole, which is not connected to the threaded cavity for bolt connection. A threaded limit rod that can be rotated by an Allen wrench is installed on the top of the threaded hole. The threaded limit rod is used to prevent the hexagonal post 112 from disengaging from the mounting base 109. The limiting plate 114 is fixed to the hexagonal post 112 by bolts, thereby limiting the rigid plastic block 110 and the battery 113. The operating device is used for manual operation of the equipment.
[0022] Secondly, a sound transmission part 115 and corresponding mating holes are provided on one side of the outer casing 101. The sound transmission part 115 is a structure of multiple through holes, which facilitates the sound transmission when the speaker 105 alarms. A mating hole is provided on the top of the outer casing 101 for setting the adjustment switch 117, the calibration button 120 and the power button 121. A mating hole for the headphone jack 118 and a mating hole for the charging port 119 are provided on the side.
[0023] Then, the PCB board 116 is detached from the housing 101 and electrically connected to the power module 103, and is located inside the housing 101; the adjustment switch 117 is disposed on the PCB board 116. The PCB board 116 is fixed to the top of the housing 101 by bolts. The PCB board 116 is provided with an induction antenna, a filtering and signal preprocessing module, an electric field signal detection and analysis module ASIC chip, a microcontroller, and the adjustment switch 117. The adjustment switch 117 is a rotary adjustment. After rotation, different combinations of switches can be used to send setting information to the microcontroller. The microcontroller can collect this setting information and automatically select the electric field strength warning range.
[0024] Furthermore, the headphone jack 118 is located on the power module 103 and electrically connected to the control module 102; the charging port 119 is located on the power module 103 and is used for charging the battery 113. The headphone jack 118 is used for headphone connection, and the charging port 119 is used for charging the battery 113. A through hole is provided on the panel 104, directly opposite the indicator light on the PCB board 116 for power display, allowing users to easily know the device's power status.
[0025] Finally, the calibration button 120 is electrically connected to the control module 102 and is located on the top left side of the housing 101; the power button 121 is electrically connected to the power module 103 and is located on the top right side of the housing 101. The calibration button 120 is used for device calibration, and the power button 121 is used for device power on / off control. Pressing and holding the power button 121 for 2 seconds powers on the device, accompanied by a voice prompt "Call on." After powering on, the device automatically performs a series of initialization operations, including self-test and parameter loading, to ensure the device is in normal working condition. The operation is simple and intuitive. The calibration button 120 controls the opening and closing of the intercom module and on-site safety distance calibration. A short press of this button will trigger a voice prompt "Call on / Call off," and intercom operation is only possible when the device is powered on. Pressing and holding this button for 3 seconds will cause the device to calibrate according to the on-site electric field strength and provide a calibration voice prompt, maximizing staff safety. The power intercom board on the power module 103 integrates modules related to wireless communication and device power supply. The full-duplex intercom function mainly relies on the communication antenna, microphone 106, speaker 105, and related signal processing circuits on the power communication board of the power module 103. The communication antenna is responsible for transmitting and receiving wireless voice signals. It can communicate wirelessly with other devices within a certain range to transmit voice data. When a user speaks, the sound is converted into an electrical signal by the microphone 106. The microphone 106 transmits the acquired analog voice signal to the signal processing circuit, which amplifies and filters it to remove noise interference and improve the quality of the voice signal. The processed voice signal is modulated and then transmitted through the communication antenna. At the receiving end, the communication antenna receives the wireless voice signal sent by other devices and converts it into an electrical signal. These signals are also demodulated, amplified, and filtered by the signal processing circuit to restore the original voice signal, which is then played back through the speaker 105, enabling real-time full-duplex intercom functionality between the two parties.
[0026] This invention addresses the problem of existing electric shock warning devices having a fixed wearing method, poor flexibility, and inconvenience due to the inability to freely switch between wearing clothing and safety helmets. During use, the control module 102 and the power module 103 work together. When a person reaches a certain voltage field level, the induction antenna on the control module 102 senses the voltage field and collects the strength signal. This information is then transmitted to the filtering and signal preprocessing module for filtering and selection. The filtering and signal preprocessing module then transmits the filtered useful information to the electric field signal detection and analysis module ASIC chip for analysis. The analysis results are then transmitted to the microcontroller, which compares the results with the internal voltage field strength fluctuation range for each level. Compared with the distance fine-tuning database, if the distance exceeds the safe range, the microcontroller controls the alarm module to work and controls the speaker 105 to emit an alarm sound. The device can be directly plugged into the plug part of the safety helmet through the safety helmet buckle 107. The safety helmet buckle 107 and the back clip 108 can form a clip structure, which is convenient for clamping and installing the device on the work clothes. This can solve the problem that the existing anti-electric shock warning device has a relatively fixed wearing method, poor flexibility, and cannot freely switch between clothing wearing method and safety helmet wearing method, which is inconvenient to use.
