Description

Technical Field

[0001] This utility model belongs to the field of power operation safety monitoring technology, and in particular relates to a safety monitoring device for power operation personnel. Background Technology

[0002] Safety monitoring devices for power workers are designed specifically to ensure the safety of power workers operating in high-voltage, high-risk environments. By integrating various sensors, monitoring, and alarm components, they can acquire the physical condition of workers in real time, provide timely warnings of potential safety risks, and thus reduce the incidence of power work accidents. In current technology, safety monitoring methods for power workers are relatively simple, typically only involving heart rate monitoring wristbands to monitor their physiological state. This single monitoring method has the following significant shortcomings in ensuring the safety of power workers: First, the inability to film the workers' operations makes subsequent review impossible. In power operations, the standardization of operations directly affects operational safety. If a safety accident or operational dispute occurs, the lack of video recordings of the operation process makes it impossible to accurately reconstruct the scene, analyze the cause of the accident, and evaluate and improve the workers' operational behavior, which is detrimental to improving the level of safety management. Second, the inability to judge the electric field force near the workers. There are many high-voltage live conductors in the power operation environment. If workers accidentally enter a high electric field environment, they are very likely to suffer serious safety accidents such as electric shock. Relying solely on heart rate monitoring wristbands cannot effectively warn of such risks.

[0003] Therefore, it is essential to invent a safety monitoring device for electrical workers. Utility Model Content

[0004] To address the above problems, this utility model proposes a safety monitoring device for power workers, and the technical solution used is as follows: A safety monitoring device for power workers includes a helmet, a strap, a mounting bracket, a camera, a control box, a storage rack, detection wristbands, a brim, a first displacement sensor, a first electric field sensor, and a buzzer. The helmet has a strap fixed to its lower end, and a camera is fixed to its upper end via the mounting bracket. The camera is electrically connected to the control box via a data cable and a power cable, and its shooting direction faces the front of the helmet. The control box is bolted to the inside of the storage rack, which is bolted to the rear side of the helmet. Two detection wristbands are placed inside the storage rack and are wirelessly connected to the control box. A brim is integrally formed on the front side of the helmet, and the first displacement sensor and the first electric field sensor are bolted to the upper side of the brim. Buzzers are bolted to both sides of the helmet. The first displacement sensor, the first electric field sensor, and the buzzer are all electrically connected to the control box via data cables and power cables.

[0005] Furthermore, the mounting bracket includes a sleeve, a connecting post, a locking block, a sliding post, a compression spring, and a locking groove. The sleeve is fixed to the top of the helmet with bolts, and the connecting post is movably arranged inside the sleeve, wherein the upper end of the connecting post is fixed to the camera with bolts. At least one locking block is slidably installed inside the sleeve, wherein the side of the locking block away from the connecting post is fixed to the sliding post by welding, and the sliding post slides through the sleeve. A compression spring is fixed between the locking block and the inner wall of the sleeve. The outer side of the connecting post has a locking groove that adapts to the locking block. This arrangement facilitates the adjustment of the camera's shooting direction and allows the camera to be detached from the helmet, thereby reducing the weight when wearing the helmet.

[0006] Furthermore, the detection wristband includes a protective shell, a strap, Velcro, a first power supply, a heart rate sensor, and a first wireless transceiver module. The strap is fixed to both ends of the protective shell, with Velcro fastened to the ends of the straps furthest from the protective shell. The first power supply, heart rate sensor, and first wireless transceiver module are fixed inside the protective shell by bolts. The first power supply is electrically connected to both the heart rate sensor and the first wireless transceiver module via power lines, and the heart rate sensor is signal-connected to the first wireless transceiver module via a data line. The detection end of the heart rate sensor is located on the outside of the protective shell. The first wireless transceiver module is wirelessly connected to the control box. This configuration enables real-time detection of the operator's heart rate.

[0007] Furthermore, the detection wristband also includes a second electric field sensor, which is fixed inside the protective shell by bolts; the second electric field sensor is electrically connected to the first power source via a power cord, and the second electric field sensor is signal-connected to the first wireless transceiver module via a data line. This configuration enables real-time detection of the electric field force at the operator's hand position.

[0008] Furthermore, the control box includes a housing, a second power supply, a controller, a data storage module, and a second wireless transceiver module. The housing is fixed inside the storage rack with bolts, and the second power supply, controller, data storage module, and second wireless transceiver module are fixed inside the housing with bolts. The second power supply is electrically connected to the camera, the first displacement sensor, the first electric field sensor, the buzzer, the controller, the data storage module, and the second wireless transceiver module via power cables. The controller is connected to the camera, the first displacement sensor, the first electric field sensor, the buzzer, the data storage module, and the second wireless transceiver module via data cables. The second wireless transceiver module is connected to the detection wristband's wireless signal. This configuration allows for the processing of data from the camera, the first displacement sensor, the first electric field sensor, and the detection wristband, and the selection of whether to issue an alarm via the buzzer based on the processing results. Furthermore, the data storage module can store the data from the camera, the first displacement sensor, the first electric field sensor, and the detection wristband for subsequent review.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the cooperation of the fixing frame and the camera, can capture the operation of the workers and store it in the control box for later review. Secondly, when in use, the shooting direction of the camera can be adjusted by changing the state of the fixing frame. At the same time, by changing the state of the fixing frame, it is easy to detach the camera from the helmet, reducing the weight when wearing the helmet.

[0010] 2. The detection wristband and the first electric field sensor of this utility model can detect the electric field force at the position of the worker's hand and head in real time during use, and transmit the detection results to the control box through the first wireless transceiver module. The control box can control the buzzer to sound an alarm based on the detection results, thereby preventing workers from accidentally entering a high electric field environment.
