Description

TECHNICAL FIELD

[0001] The utility model relates to high voltage electric field early warning technical field, concretely is a safety helmet for high voltage electric field early warning. BACKGROUND

[0002] Most of the existing safety helmet mainly focuses on the physical protection of the head, such as resisting impact, etc., and there is obvious deficiency for the safety protection of the operating personnel in the high voltage electric field environment. In the operating scene involving high voltage electric field, such as power construction, electrical equipment maintenance, etc., the traditional safety helmet cannot effectively monitor and warn the electric field situation on the spot. The operating personnel may face the risk of electric shock without knowing the situation of entering the high voltage electric field area, and the existing safety helmet cannot give effective warning to the operating personnel in advance, which increases the possibility of accidents.

[0003] Even if part of the safety helmet may have certain induction to the electric field, the induction range is limited and cannot fully cover the space around the head, which easily leads to the omission of the detection of the electric field. For example, some simple static induction devices may only be able to induce the electric field in a specific direction or limited area, and it is difficult to accurately perceive the electric field changes from different angles, which cannot provide comprehensive electric field information for the operating personnel, thereby affecting the timely judgment and avoidance of danger. At the same time, there is a lack of multi-dimensional prompt, for example, static induction may be more sensitive to early changes of the electric field, but it is easily affected by other static interference in the environment; the response of the luminous material is relatively intuitive, but there may be a certain response delay. Therefore, there may be false positives and false negatives, which reduces the accuracy of the warning. And lack of effective warning to the surrounding personnel.

[0004] In view of this, a safety helmet for high voltage electric field early warning is provided to overcome the above problems. UTILITY MODEL CONTENTS

[0028] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0029] Refer to Figures 1-3 As shown in figure 1, a safety helmet for high-voltage electric field early warning, including cap body 7, the top of cap body 7 is provided with static induction early warning strip 1 and temperature sensitive element 4, static induction early warning strip 1 is herringbone, static induction early warning strip 1 is made of static induction material, the front end of static induction early warning strip 1 is located at the outer front side of cap body 7, the rear two ends of static induction early warning strip 1 are located at the outer rear side of cap body 7, and towards the left and right sides of cap body 7, the brim of cap body 7 is installed with fluorescent material coating 2, sound sensor 3 and central control box 5, fluorescent material coating 2 is annular, the rear side of cap body 7 is installed with buzzer 6, static induction early warning strip 1, fluorescent material coating 2, sound sensor 3, temperature sensitive element 4 and buzzer 6 are all connected with central control box 5 electric wire;

[0030] The upper integral molding of central control box 5 has charge detection circuit, fluorescent material response monitoring circuit, sound signal processing circuit and temperature detection circuit respectively matched with static induction early warning strip 1, fluorescent material coating 2, sound sensor 3 and temperature sensitive element 4;

[0031] The inside of cap body 7 is installed with head support, the bottom of head support is installed with hat band 12, through head support and hat band 12, the head of wearer is protected and used for wearing cap body 7;

[0032] When the staff wearing cap body 7 enters high-voltage electric field area, static induction early warning strip 1 made of static induction material first senses electric field and generates static charge, and charge detection circuit transmits signal to central control box 5, when weak, triggers primary alarm, and emits slight buzzing sound through buzzer 6;

[0033] Under the action of electric field, the fluorescence characteristic of fluorescent material coating 2 changes, and the change information is captured by monitoring circuit and transmitted to central control box 5, when the fluorescence intensity enhances or the color change reaches the set threshold value, central control box 5 can adjust the alarm intensity according to the situation, so that buzzer 6 emits slightly higher volume buzzing sound, and at the same time, fluorescent material coating 2 warns the surrounding personnel, and the safety of the surrounding personnel is improved;

[0034] When the sound sensor 3 detects the discharge sound generated by air ionization, the signal is transmitted to the control box 5 after processing, and once the sound characteristics meet the characteristics related to the high-voltage electric field, the control box 5 further strengthens the alarm and continuously emits a higher volume of beeping sound;

[0035] When the temperature-sensitive element 4 detects that the surrounding temperature rises due to the conversion of electric field energy, and when the temperature change exceeds the threshold value, it also sends a signal to the control box 5, and the control box 5 considers the signal comprehensively. If multiple detection methods indicate that they are in a strong high-voltage electric field environment at the same time, the strongest alarm mode is triggered, and a piercing beeping sound is continuously emitted to ensure that workers can detect the danger in time and take appropriate safety measures.

[0036] Further, the top of the cap body 7 is provided with a person-shaped heat exchange pipe 9, and the electrostatic induction warning strip 1 is bonded to the outer wall of the heat exchange pipe 9.

[0038] Working principle:

[0039] When the worker wearing the cap body 7 enters the high-voltage electric field area, the electrostatic induction warning strip 1 made of electrostatic induction material first senses the electric field and generates static electricity. The charge detection circuit transmits the signal to the control box 5. When it is weak, the primary alarm is triggered, and a slight beeping sound is emitted through the buzzer 6.

[0040] The fluorescent material coating 2 changes its fluorescent properties under the action of the electric field, and the change information is captured by the monitoring circuit and transmitted to the control box 5. When the fluorescent intensity increases or the color changes reach the set threshold, the control box 5 can adjust the alarm intensity according to the situation, so that the buzzer 6 emits a slightly higher volume of buzzing sound; at the same time, the fluorescent material coating 2 warns the surrounding personnel, improving the safety of the surrounding personnel;

[0041] After the sound sensor 3 detects the discharge sound generated by air ionization, the signal is processed and transmitted to the control box 5. Once the sound characteristics meet the characteristics related to high-voltage electric field, the control box 5 further strengthens the alarm and continuously emits a higher volume of buzzing sound;

[0042] The temperature sensitive element 4 detects the increase of ambient temperature due to the conversion of electric field energy. When the temperature change exceeds the threshold, it also sends a signal to the control box 5. The control box 5 considers the signals comprehensively. If multiple detection methods indicate that they are in a strong high-voltage electric field environment at the same time, the strongest alarm mode is triggered, and a loud buzzing sound is continuously emitted to ensure that the workers can detect the danger in time and take appropriate safety measures;

[0043] By setting the mirror 13 facing the face, the light emitted by the fluorescent material coating 2 can be reflected to remind the wearer in the first time, further improving the safety of the wearer.

[0044] Different early warning methods detect high-voltage electric field based on different physical principles, and they have complementarity. Static induction may be more sensitive to early changes in electric field, but it is easily affected by other static electricity in the environment. The response of fluorescent material is relatively intuitive, but there may be a certain response delay. Combining multiple methods can integrate the advantages of different methods, reduce false positives and false negatives, and improve the accuracy of early warning.

[0045] By bonding the static induction early warning strip 1 on the exposed outer wall of the heat exchange pipe 9, the top and both sides of the cap body 7 can be sensed, thereby increasing the sensing range of the static induction early warning strip 1 and improving the high-voltage electric field early warning effect. By setting the shell 8, the heat exchange pipe 9 and the exhaust port 11, the head of the wearer is conveniently cooled, and the comfort during wearing is improved. Moreover, the back two ends of the heat exchange pipe 9 are inclined downward and face the left and right sides of the cap body 7, and there is a distance between the heat exchange pipe 9 and the temperature sensitive element 4, so the accuracy of the temperature sensitive element 4 is not easily affected.
