[0024] In the description of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, or electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0025] See also Figures 1 to 3 A low-voltage arc safety protective mask includes: a helmet 100, the helmet 100 is used to be worn on a person's head, the helmet 100 is movably provided with a protective panel 200, the helmet 100 is movably provided with a telescopic frame 300, one end of the telescopic frame 300 is provided with a charging sensor 110 and a temperature sensor 120, the charging sensor 110 is used to detect the electric field strength in the environment to generate a first signal, the temperature sensor 120 is used to detect the temperature in the environment to generate a second signal, the helmet 100 is provided with an alarm module, the charging sensor 110, the temperature sensor 120 and the alarm module are electrically connected to a processing module, the processing module is used to set a safety threshold of the environment, when the value of the first signal and / or the second signal is greater than the safety threshold, the processing module controls the alarm module to generate an alarm signal.

[0026] The low-voltage arc safety protective mask of the above structure, when people wear the helmet 100, the protective panel 200 can provide protection in a variable power working environment. By adjusting the telescopic frame 300 to change the position of the charge sensor 110 and the temperature sensor 120, the charge sensor 110 can better detect the electric field strength of the environment in real time to generate a first signal, and the temperature sensor 120 can better detect the temperature change of the environment in which it is located to generate a second signal. When an arc or arc light is generated in the environment, the value of the first signal or the second signal is greater than the set safety threshold, and the processing module controls the alarm module to generate an alarm signal, thereby enabling real-time detection of various dangerous factors such as arcs, electric shocks, arc light, and high temperatures. This helps prompt operators to take corresponding preventive measures in a timely manner, thereby improving the safety warning effect of operators in a variable power environment and significantly reducing the accident rate caused by operators during the power equipment maintenance process.

[0027] It is understandable that the charged sensor 110 may be an antenna sensor, which receives specific electromagnetic wave signals to detect partial discharge, which will not be described in detail here.

[0028] See also Figure 1 and Figure 2 Furthermore, the telescopic frame 300 includes a first link frame 310 rotatably mounted on the helmet 100. One end of the first link frame 310 is rotatably connected to a second link frame 320. The charge sensor 110 and the temperature sensor 120 are mounted on one end of the second link frame 320, and the protective panel 200 is located below the second link frame 320. Specifically, the rotational positions of the first link frame 310 and the second link frame 320 are tightly fitted, allowing the first link frame 310 and the second link frame 320 to stabilize in corresponding positions after rotation by an external force, thereby changing the distance by which the charge sensor 110 and the temperature sensor 120 can be extended or retracted relative to the helmet 100.

[0029] See also Figure 1 and Figure 2 Furthermore, the second connecting rod frame 320 includes two opposing mounting rods 321, with a mounting block 322 interposed between the two mounting rods 321. The charge sensor 110 and the temperature sensor 120 are mounted on the mounting block 322, making it easy to move the mounting block 322 and facilitating fine-tuning of the positions of the charge sensor 110 and the temperature sensor 120. The second connecting rod frame 320 also includes two opposing mounting plates 323, with the two mounting rods 321 respectively mounted at the upper ends of the corresponding mounting plates 323. A rotating shaft is connected between the two mounting plates 323. The first connecting rod frame 310 is provided with a mounting hole through which the rotating shaft can be movably inserted, thereby enabling the first connecting rod frame 310 and the second connecting rod frame 320 to rotate relative to each other.

[0030] See also Figures 1 to 3 Furthermore, the device further includes an arc-shaped mounting bar 210, with mounting posts 211 disposed at opposite ends of the mounting bar 210. The protective panel 200 is provided with latch holes that mate with the mounting posts 211. The protective panel 200 is arc-shaped and disposed on the mounting bar 210, so that the protective panel 200 can form an outer arc-shaped surface surrounding the head, thereby providing better safety protection for the operator. The combination of the mounting posts 211 and the latch holes facilitates the installation and removal of the protective panel 200. It is understood that the protective panel 200 and the mounting bar 210 can also be mated using bolts or snaps, which will not be described in detail.

[0031] See also Figures 1 to 3Furthermore, the helmet 100 includes a hemispherical shell 101 for wearing, and a side extension bar 102 is provided at the lower end of the hemispherical shell 101 along a horizontal extension, and a mounting bar 210 is placed above the side extension bar 102. Both ends of the mounting bar 210 are connected with a wearing rope 220, and the wearing rope 220 is located outside the hemispherical shell 101. Among them, the interior of the hemispherical shell 101 forms a accommodating cavity that can accommodate a person's head, thereby making it convenient for people to wear the helmet 100. When the wearing rope 220 is put on a person's head, the protective panel 200 faces the person's face to form a protective surface. In addition, in order to reduce the shaking of the protective panel 200 during use, the hemispherical shell 101 is provided with an arc groove, and the sealing plate 230 can be inserted into the arc groove to fix the position of the protective panel 200.

[0032] See also Figures 1 to 3 Furthermore, the outer peripheral wall of the hemispherical shell 101 is provided with a curved strip 103, and the mounting strip 210 is connected to a sealing plate 230. The sealing plate 230 has a curved notch facing the curved strip 103. When the wearing cord 220 is placed on the head, the curved strip 103 abuts against the inner wall of the curved notch. Specifically, during use, when the wearing cord 220 is placed on the head, the sealing plate 230 moves under the action of the wearing cord 220 to press against the curved strip 103, thereby allowing the protective panel 200, sealing plate 230, and helmet 100 to jointly provide better protection for the head.

[0033] See also Figures 1 to 3 Furthermore, the wearing rope 220 is an elastic rope with multiple turns of spiral arrangement on the mounting bar 210, so that the wearing size of the wearing rope 220 can be changed to adapt to the use of different operators. A pad 221 is provided in the middle of the elastic rope, so that the pad 221 is used to increase the contact area between the elastic rope and the human head, thereby reducing the pressure to improve people's wearing comfort.

[0034] See also Figure 2 Furthermore, the alarm module includes a speaker 130 provided on the top of the helmet 100, and the speaker 130 is provided with a display screen 131 electrically connected to the processing module. Specifically, when the value of the first signal or the value of the second signal is greater than the set installation threshold, the processing module controls the speaker 130 to emit a sound, thereby prompting the operator to take preventive measures in time. Among them, the display screen 131 is used to intuitively present relevant data on the electric field strength or temperature in the environment, which is helpful to help the wearer understand the safety status of the working environment at any time. In addition, the alarm module can also generate an alarm signal by flashing an LED light or a buzzer. It is understandable that the processing module can adopt a PLC module, which will not be described in detail.

[0035] Furthermore, the protective panel 200 is made of a composite material and has a transparent area for viewing, which is provided with an anti-glare coating. Specifically, by using a composite material (such as polycarbonate), the protective panel 200 has excellent insulation properties and can effectively block high-temperature heat radiation caused by electric arcs and arc light, thereby preventing damage to the wearer's facial skin and vision. At the same time, the transparent area is provided with an anti-glare coating, which is a UV coating or a thermal curing coating. This allows the operator to maintain a clear and unobstructed view even in strong light environments, thus meeting the needs of operations in changing environments.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
