Abstract
Description
Technical Field
[0001] This utility model relates to the field of power equipment, specifically to an insulating boot heating device and an insulating boot. Background Technology
[0002] Insulating boots are essential auxiliary safety equipment for power substation operations. They offer good insulation, are easy to carry, and are used to ensure the safety of operators. However, in winter, insulating boots become brittle and hardened in low-temperature environments, making them prone to damage. Especially when operators are wearing them during various operations, the boots often crack or break due to the stress they bear, reducing their insulation performance and potentially leading to electric shock accidents. Furthermore, wearing cold, stiff insulating boots can cause operators to catch a cold due to the biting cold, and the stiffness can also hinder operation, which is detrimental to safe production.

[0017] This utility model provides a heating device for insulating boots, used to heat insulating boots, such as... Figure 1 As shown, the device includes a bushing 1 that is the same shape as the insulating boot and can be inserted into the insulating boot, and an electric heating wire 2 fixed to the bushing 1. The heating device for the insulating boot also includes a thermostat 3 connected to the electric heating wire. The thermostat 3 can detect and control the temperature of the electric heating wire. When the set temperature is reached, the thermostat 3 disconnects and stops heating.
[0018] The insulating boot heating device of this invention heats the insulating boot in low-temperature environments using a heating wire 2, and controls the heating temperature using a temperature controller 3, typically to body temperature. The temperature controller can be set to any temperature between 35℃ and 45℃; in this embodiment, it is set to 40℃. At this temperature, the insulating boot remains warm and soft, preventing the operator from experiencing a cold touch. Simultaneously, at this temperature, the insulating boot is less prone to cracking or breaking under stress, thus maintaining its insulation performance.
[0019] In this embodiment, the bushing 1 includes an inner layer and an outer layer. The heating wire 2 is located between the inner and outer layers, with the inner layer being made of cotton material and the outer layer being made of insulating cotton material. The heating wire 2 can be fixed to the bushing 1 by bonding or sewing. The heating wire 2 can heat the insulating boot when energized, and as a metal wire, it also supports the bushing 1 to maintain the same shape as the insulating boot, thus keeping the bushing 1 in close contact with the inner wall of the insulating boot and better conducting the heat from the heating wire 2. In other embodiments, the bushing may be a single layer, made of rubber or other elastic and deformable materials.
[0020] like Figure 1 As shown, the bushing 1 includes a cylindrical portion 11 and a boat-shaped portion 12 that can extend into the space between the upper and lower part of the insulated boot. The heating wire 2 is spirally arranged in the cylindrical portion 11 and the boat-shaped portion 12. A single heating wire 2 can be arranged throughout the bushing 1, that is, extending from the uppermost end of the cylindrical portion 11 to the frontmost end of the boat-shaped portion 12. Alternatively, two or more heating wires 2 can be arranged in parallel.
[0021] In this embodiment, the bushing 1 has a power supply interface 4 at the uppermost end of its cylindrical part 11 that is connected to the heating wire 2. The power supply interface 4 can be connected to a 5V mobile power supply via a power cord. When the thermostat is closed, the mobile power supply supplies power to the heating wire 2 to make it heat up.
[0022] This utility model also provides an insulated boot, including a boot body and a heating device that extends into the boot body and fits against the inner wall of the boot body. The heating device is as described above. In this embodiment, the heating device is separable from the boot body. The bushing 1 can be removed from the insulated boot after heating to a set temperature, and then the operator can wear the insulated boot, which is safer.
[0023] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions made by those skilled in the art within the spirit and scope of this utility model also fall within the scope of protection of this utility model.
