If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0026] The following is combined with Figure 1-3 , an embodiment of the electric field induction safety shoe of the utility model is further described in detail.

[0027] An electric field sensing safety shoe, such as Figure 1 , 2 As shown, it includes a sole 1 made of insulating material and an upper 2 arranged on the sole 1, the sole 1 is equipped with an electric field sensing sensor 3, a warning device 4 and a power module 5, the electric field sensing sensor 3 is used to sense the intensity of the surrounding electric field, and the electric field sensing sensor 3 is connected to the warning device 4 by signal; when the electric field sensing sensor 3 detects that the electric field exceeds the set safety threshold, the warning device 4 sends out an alarm or vibrates; the power module 5 provides power to the electric field sensing sensor 3 and the warning device 4; a flexible display 6 is arranged on the upper 2 near the front end of the sole 1, and the flexible display 6 is electrically connected to the electric field sensing sensor 3 so that it can detect and display the current threshold of the electric field and the location of the fault area in real time.

[0028] Specifically, the shoe body is made of highly wear-resistant and highly elastic rubber material to provide good grip and comfort; the built-in electric field sensing sensor 3 is installed on the inner side of the tongue, close to the toe part, and the electric field sensing sensor 3 can be a capacitive, inductive or other sensor suitable for sensing electric fields; the warning device 4 is installed on the heel part of the sole 1, and the power module 5 is a rechargeable lithium-ion battery, which is connected to an external charging device through wireless charging technology; the flexible display is made of transparent LED material; it is beautiful and does not affect the use. When the operator wears the safety shoes and enters a strong electric field area, the electric field sensing sensor 3 detects the change in electric field strength and transmits the signal to the warning device 4, triggering an alarm and vibration to remind the wearer to pay attention to safety.

[0029] It is worth noting that the shoe body in the utility model provides a basic structure for operators to wear, which can be any shoe type suitable for high-voltage live working, such as safety boots, work shoes, etc.; at the same time, the shoe body can also be made of wear-resistant, oil-resistant, and non-slip materials to adapt to different working environments; in addition, the capacity of the power module 5 can be expanded externally to support longer continuous work. In terms of usage, before starting work, the operator can also connect to the safety shoes through a mobile phone application, set personal safety thresholds, and view real-time electric field strength data; when the electric field strength is detected to exceed the set threshold, the mobile phone application will also receive a notification so that the operator can take corresponding safety measures.

[0030] In this embodiment, if Figure 3 As shown, the upper 2 is sequentially provided with an insulating tape layer 21, a waterproof hard rubber layer 22 and a breathable flannel layer 23 from the outside to the inside. The insulating tape layer 21, the waterproof hard rubber layer 22 and the breathable flannel layer 23 are bonded together by glue, and a plurality of ventilation holes 231 are provided on the breathable flannel layer 23.

[0031] In order to further improve the functionality of the safety shoes, the upper 2 is composed of a multi-layer protective structure, among which the outermost insulating tape layer 21 can prevent electric shock accidents caused by entering the high-voltage electric field and protect the personal safety of the operators. The middle layer is set as a waterproof hard rubber layer 22 to further avoid the danger of leakage and can prevent rainwater from entering the shoe body and causing electric shock during operation. The inner layer is set as a breathable flannel layer 23 to improve the comfort of the wearer and avoid the interior of the shoe body being hot and humid during long-term operation, which affects the wearer's wearing experience.

[0032] In this embodiment, the electric field sensing sensor 3 includes a voltage sensor 31 and a current sensor 32 , and the voltage sensor 31 and the current sensor 32 are arranged at the bottom end of the sole 1 .

[0033] Specifically, the sensitivity and measurement range of the electric field sensing sensor 3 should be selected and calibrated according to the actual application scenario. In order to monitor the electric field strength more accurately, a voltage sensing sensor is combined with a current sensing sensor for detection, and the electric field strength near the operation is obtained by combined calculation, so as to remind the wearer to pay attention to the existence of the surrounding high-voltage electric field; at the same time, it can also effectively prevent electric shock accidents caused by ignoring the high-voltage electric field and improve operation safety.

[0034] In this embodiment, the warning device 4 includes a sound alarm 41, a vibrator 42 and a flashing light 43. The sound alarm 41 is a buzzer; the vibrator 42 is composed of a vibration motor and a vibration panel, and the vibration motor and the vibration panel are connected by an eccentric cam transmission; the flashing light 43 is sewn on the side walls around the sole 1; the sound alarm 41, the vibrator 42 and the flashing light 43 synchronously issue an alarm.

[0035] Specifically, when it is detected that the electric field strength exceeds the set safety threshold, the warning device 4 respectively emits a sound alarm, a vibration alarm and a light alarm through the sound alarm 41, the vibrator 42 and the flashing light 43; wherein, the sound alarm 41 can be a buzzer or other type of sound-generating device, and the volume of the alarm and the intensity of the vibration should be sufficient to attract the wearer's attention, but not too harsh or strong, so as not to affect the normal work of the operator; and the driving source of the vibrator 42 can adopt a small vibration motor or a piezoelectric element, and the small vibration motor or the piezoelectric element is used to drive the eccentric cam to rotate, so that the vibration plate continues to vibrate under the rotation of the eccentric cam; and the light alarm uses flashing colored lights for reminders, and its flashing lights 43 are sewn on the side walls around the sole 1 and connected to the power module 5 through wires; the design of the warning device 4 ensures that the wearer can be clearly reminded of danger signals in various environments, thereby improving the safety performance of the operation.

[0036] In this embodiment, the power module 5 is rechargeable, and the power module 5 is connected to an external charging device through wireless charging technology.

[0037] Specifically, the power module 5 can be a battery, such as a lithium battery or a nickel-metal hydride battery. For ease of use and maintenance, the power module 5 can be designed to be rechargeable and connected to an external charging device via wireless charging technology, and the capacity of the power module 5 is sufficient to support the continuous operation of the safety shoes within the normal service life.

[0038] At the same time, a slot 12 for installing a dry battery is provided on the sole 1, and a charging interface 13 is provided on one side of the slot 12. The dry battery can be used as a backup power source for the safety shoes. When the power mode is out of power or abnormal, the dry battery can provide a short power supply for the safety shoes. In addition, in order to facilitate the charging method of the power module 5, in addition to the wireless coil induction charging method, the charging interface 13 provided on the sole 1 can also be used for wired charging. It is worth noting that the structure of the charging interface 13 can adopt one of the lightning interface, type-c interface or USB interface that is the same as the mobile phone charging structure.

[0039] In this embodiment, anti-skid protrusions 11 are evenly arranged at the front and rear ends of the bottom of the sole 1 that contacts the ground, and the anti-skid protrusions 11 and the sole 1 are an integrally formed structure.

[0040] Specifically, the purpose of setting the anti-skid protrusion 11 at the bottom of the sole 1 is not only to prevent slipping, but also to protect the electric field sensing sensor 3. One side of the electric field sensing sensor 3 is flush with the sole 1. During wearing, the anti-skid protrusion 11 protrudes outward, so that the electric field sensing sensor 3 avoids friction with the ground, thereby affecting the detection result of the electric field strength safety threshold. In addition, in addition to the anti-skid structure design of the anti-skid protrusion 11, a rubber sole with deep textures can also be used to improve the grip on wet or uneven ground.

[0041] The working principle of this utility model:

[0042] Before performing high-voltage live operations, the operator wears electric field sensing safety shoes and ensures that they are worn correctly and the shoelaces are tied tightly; at the same time, when the operator enters the electric field for operation, only the induction switch in the sole 1 automatically starts the power supply of the electric field sensing safety shoes, so that it starts the working mode, and the power module 5 starts to supply power to the electric field sensing sensor 3 and the warning device 4; when entering the high-voltage electric field environment, the electric field sensing sensor 3 starts to work, automatically senses the intensity of the surrounding electric field, monitors the environmental safety situation in real time, and displays the intensity value of the electric field through the flexible display 6, and at the same time, the electric field sensing sensor 3 will continue to scan the surrounding environment. Once it is detected that the electric field intensity exceeds the safety threshold, the warning device 4 will issue a sound alarm, a light alarm, and the sole 1 will vibrate to remind the wearer to pay attention to safety; so that the operator can take safety measures in time according to the warning signal, avoid entering the high electric field area or take corresponding protective measures; at the same time, the wearer can quickly evaluate the surrounding environment according to the fault location displayed by the flexible display, judge whether there are other safety hazards, and take necessary protective measures, such as keeping a distance or using insulating tools.

[0043] Through the above-mentioned structure and method of use, the electric field sensing safety shoes of the utility model can effectively remind operators to pay attention to the existence of surrounding high-voltage electric fields, thereby preventing electric shock accidents; at the same time, they can also be customized according to different working environments and personal needs, such as adjusting the capacity of the power module 5, selecting different types of sensors and warning devices 4, etc.; thereby not only improving the safety of operations, but also providing more comprehensive protection for operators through real-time monitoring and warning functions.

[0044] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
