Description

Technical Field

[0001] The present invention relates to the technical field of insulating and isolating protection tools, and particularly to an insulating and isolating protection tool for 0.4kV low-voltage live working and a wearing method thereof. Background Art

[0002] The operation of 0.4kV low-voltage overhead lines involves the installation, maintenance, repair, and fault handling of low-voltage power overhead lines. Such operations are usually responsible for supplying power to residential areas, commercial areas, and small industrial users in the power supply system. Although the voltage is relatively low, there is still a certain degree of electrical danger. Therefore, when carrying out operations, safety regulations must be strictly observed and appropriate protection tools must be used. Common insulating and isolating protection tools include insulating ropes, insulating tapes, insulating isolating rods, insulating gloves, insulating tools, etc.;

[0003] For the existing insulating and isolating protection tools for 0.4kV low-voltage overhead line operations, the electrical isolation protection for operators is usually provided by the insulating materials on the surface. During long-term use, the insulating materials may be affected by environmental factors such as ultraviolet rays, moisture, and temperature changes, resulting in a gradual decrease in insulation performance (for example, ultraviolet radiation or humid weather is likely to cause cracks and aging in the insulating layer, thereby reducing its isolation effect); at the same time, during the contact process between the insulating materials and metal components, tools, or other objects, wear or cracks may also occur, leading to local failure and thus the risk of electrical leakage;

[0004] Among the existing insulating and isolating protection tools, insulating gloves, as the most direct and effective insulating protection equipment, have some potential problems; firstly, wearing insulating gloves requires two-handed operation. Especially during high-altitude operations, the staff needs to maintain balance, and the wearing and use of gloves may increase the difficulty of maintaining balance, thereby increasing the risk of falling; secondly, due to the special working environment, when the staff is working at high altitude, it may be difficult to timely check the damage or aging of the gloves. Once the gloves are damaged or aged and cannot be discovered and replaced in time, the insulating effect of the gloves may be lost, thereby increasing the risk of electric shock. Summary of the Invention

[0005] Aiming at the above deficiencies, the present invention provides an insulating and isolating protection tool for 0.4kV low-voltage live working and a wearing method thereof, which can timely detect the damage and aging of the gloves, and the entire replacement process does not require two-handed operation, so as to achieve the effect of timely detecting and quickly replacing the insulating fabrics on the palm and finger parts, and is beneficial for the maintenance personnel to maintain balance during high-altitude operations.

[0053] Embodiment 1

[0054] Please refer to Figure 1-11 , an insulating isolation and protection tool for 0.4 kV low-voltage live working, including a hand insulation module and a waist storage module. The waist storage module includes a waistband 31, and side hanging boxes 33 are installed on both sides of the waistband 31;

[0055] The hand insulation module includes a dorsal hand insulation fabric 11, a wrist insulation fabric 12, and a palm insulation fabric 15. The dorsal hand insulation fabric 11 is arranged to cover the dorsal hand. A fixed strap 17 is fixedly connected to the inner side of the dorsal hand insulation fabric 11. The fixed strap 17 is arranged around the palm and passes through the palm center. The wrist insulation fabric 12 is sleeved on the wrist. One side of the wrist insulation fabric 12 is fixedly connected to the dorsal hand insulation fabric 11. An electric current alarm device is installed on the other side of the wrist insulation fabric 12. The palm insulation fabric 15 is arranged at the palm. The lower end of the palm insulation fabric 15 is connected with an insulating finger sleeve 16. The palm insulation fabric 15 and the insulating finger sleeve 16 can be stored in the side hanging box 33. A locking structure is arranged between the palm insulation fabric 15 and the dorsal hand insulation fabric 11. The locking structure is used to quickly unlock and separate the wrist insulation fabric 12 from the dorsal hand insulation fabric 11;

[0056] Current induction layers 152 are provided in the dorsal hand insulation fabric 11, the wrist insulation fabric 12, the palm insulation fabric 15, and the insulating finger sleeve 16. The current induction layer 152 is electrically connected to the electric current alarm device.

[0057] In the above solution, it should be noted that the back-of-hand insulating fabric 11, the wrist insulating fabric 12, the palm insulating fabric 15, and the insulating finger sleeves 16 are all designed with a multi-layer structure, and the current induction layer 152 is located in the middle sandwich of the multi-layer structure;

[0058] During electrical work, the palm and finger parts need to repeatedly contact electrical components for a long time. Therefore, the wear of the palm and finger parts is often more serious than that of the wrist and back-of-hand parts, and the positions of aging and damage usually occur first in the palm and finger parts. Therefore, the palm insulating fabric 15 and the insulating finger sleeves 16 are designed to be separable and are connected and fixed to the back-of-hand insulating fabric 11 through a locking structure;

[0059] The insulating fabric with a multi-layer structure design guides the current to the current alarm device through the current induction layer 152 when the surface insulating material leaks. The current alarm device alarms to remind the user, and then through the separable design and the locking structure, the back-of-hand insulating fabric 11 and the palm insulating fabric 15 are quickly separated with one hand, and then the new palm insulating fabric 15 and the insulating finger sleeves 16 in the waist side hanging box 33 are replaced. The entire replacement process does not require both hands to operate, so as to achieve the effect of timely detecting and quickly replacing the insulating fabric of the palm and finger parts, and it is beneficial for maintenance personnel to maintain balance during high-altitude operations. Greatly improves the safety of live working.

[0060] As Figure 6-8 shown, the current alarm device includes an insulating strap 13. The insulating strap 13 is fixedly installed at one end of the wrist insulating fabric 12 close to the forearm. One end of the insulating strap 13 is provided with an opening. The other end of the insulating strap 13 surrounds the wrist for one week and passes through the opening at the other end. The current alarm device includes a current induction unit 10. The current induction unit 10 is fixedly installed on the surface of the insulating strap 13. The current induction unit 10 is electrically connected to the current induction layer 152 in the wrist insulating fabric 12. A warning light 14 is also provided on the surface of the insulating strap 13. The warning light 14 is electrically connected to the current induction unit 10.

[0061] In the above embodiment, it should be noted that the insulating strap 13 is an insulating closing strap, which has the function of fixing the wrist insulating fabric 12 at the wrist; the current induction unit 10 monitors the change of current in real time through a Hall sensor. Its function is to detect the current magnitude and judge whether it exceeds the set safety threshold. When the current reaches or exceeds the preset safety threshold, the current induction unit 10 generates a signal (usually a high-level signal or a closed switch) through its built-in circuit. This signal is transmitted to the warning light 14. The warning light 14 is connected to a relay or a switch circuit. The warning light 14 is composed of an LED light or other types of signal indicator lights. When the current induction unit 10 detects an abnormal current, the relay or the switch circuit is used to activate the warning light 14 to emit a warning signal;

[0062] As Figure 10 , 11 shown, the back - hand insulating fabric 11, wrist insulating fabric 12, palm insulating fabric 15 and insulating finger cots 16 are all set as multi - layer insulating structures. The back - hand insulating fabric 11, wrist insulating fabric 12, palm insulating fabric 15 and insulating finger cots 16 include an outer insulating layer 151, a current induction layer 152 and an inner insulating layer 153. The outer insulating layer 151 is arranged on the outermost side, the current induction layer 152 is arranged between the outer insulating layer 151 and the inner insulating layer 153, the outer insulating layer 151 is arranged on the skin side. The current induction layer 152 in the insulating finger cots 16 is electrically connected to the current induction layer 152 in the palm insulating fabric 15, and the current induction layer 152 in the back - hand insulating fabric 11 is electrically connected to the current induction layer 152 in the wrist insulating fabric 12. The edge of the current induction layer 152 of the palm insulating fabric 15 can be magnetically adsorbed to the edge of the current induction layer 152 of the back - hand insulating fabric 11.

[0063] It should be noted that when the outer insulating layer 151 of the palm insulating fabric 15 and the insulating finger cots 16 is damaged and leaks, the current will be guided to the current induction unit 10 through the current induction layer 152. When the current induction unit 10 detects an abnormal current, it activates the warning light 14 through a relay or a switch circuit to emit a warning signal, so as to warn the staff. The current induction layer 152 is made of a composite material, which combines carbon nanotubes or graphene with ferromagnetic materials (such as iron oxide, iron, cobalt, etc.), and a composite material that is both conductive and magnetic can be obtained. The edges of the back - hand insulating fabric 11, wrist insulating fabric 12, palm insulating fabric 15 and insulating finger cots 16 can be fitted together through the magnetic attraction between the current induction layers 152.

[0064] As Figure 1 - Figure 5 shown, the belt 31 is worn around the user's waist. Fixed sockets 35 and fixed pins 36 are respectively installed at both ends of the belt 31. The fixed socket 35 is inserted and fixed in the fixed pin 36. A front buckle 32 is arranged at the position of the belt 31 close to the user's abdomen. A front buckle 32 is arranged on the back of the front buckle 32. A belt - passing clamping plate 34 is also arranged on one side of the side hanging box 33 close to the belt 31. The belt 31 passes through the belt - passing clamping plates 34 of the side hanging box 33 and the front buckle 32. A side positioning cover 29 is fixedly installed in the middle of the side hanging box 33, and a front positioning cover 30 is fixedly installed in the middle of the front buckle 32.

[0065] It should be noted that the belt 31 is made of insulating material. The fixed socket 35 and the fixed pin 36 are metal buckles. The belt 31 is wound around the waist and the fixed pin 36 is inserted into the fixed socket 35 to achieve the function of wearing the belt. The side hanging box 33 and the front buckle 32 are also made of insulating material, and the front positioning cover 30 and the side positioning cover 29 are made of magnetic material.

[0066] As Figure 7 , Figure 6 , Figure 9 and Figure 10 shown, the locking structure includes a connector housing 24 which is fixedly installed on the side of the palm insulating fabric 15 close to the palm. At the end of the connector housing 24 far from the palm insulating fabric 15, a locking cover plate 25 is fixedly installed. A round hole is provided in the middle of the locking cover plate 25. Slots 26 are provided on the opposite sides inside the round hole of the locking cover plate 25. A limiting block 27 is fixedly installed at the bottom of the locking cover plate 25 on one side of the slot 26. A magnetic protrusion 28 is fixedly installed on the side of the palm insulating fabric 15 far from the palm. The magnetic protrusion 28 can be inserted into the side positioning cover 29 or the front positioning cover 30 and magnetically adsorbed to the side positioning cover 29 or the front positioning cover 30. The locking structure includes a connecting piece 21 which is fixedly installed at the position of the fixed strap 17 close to the palm. A connecting column 22 is provided on the side of the connecting piece 21 far from the fixed strap 17. The connecting column 22 can be inserted into the middle round hole of the locking cover plate 25. Locking pins 23 are fixedly installed on both sides of the connecting column 22. The locking pins 23 can pass through the slots 26.

[0067] It should be noted that the connector housing 24, the locking cover plate 25, the limiting block 27, the connecting piece 21 and the connecting column 22 are all made of insulating plastic, which is light and durable. By inserting the connecting column 22 and the locking pin 23 on the lower connecting piece 21 into the connector housing 24 and rotating the palm insulating fabric 15 to drive the connector housing 24 to rotate, the locking pin 23 rotates 120° and abuts against the limiting block 27 to achieve the effect of locking and connecting the palm insulating fabric 15 and the fixed strap 17.

[0068] Inserting the magnetic protrusion 28 into the side positioning cover 29 or the front positioning cover 30 can position the magnetic protrusion 28 and prevent the palm insulating fabric 15 from rotating as the hand rotates.

[0069] When it is necessary to replace the palm insulation fabric 15, move the palm to the abdomen, insert the magnetic protrusion 28 on the old palm insulation fabric 15 into the front positioning cover 30 of the front buckle 32. The front positioning cover 30 is engaged with the magnetic protrusion 28 to fix the old palm insulation fabric 15. Then rotate the palm to drive the locking pin 23 to rotate reversely by 120° and disengage from the slot 26, so that the connecting column 22 is separated from the connector housing 24. Finally, move the palm to the waist side, insert the connecting column 22 on the connecting piece 21 and the locking pin 23 into the connector housing 24 of the new palm insulation fabric 15 in the side hanging box 33. Rotate the palm insulation fabric 15 to drive the connector housing 24 to rotate, so that the locking pin 23 rotates by 120° and abuts against the limit block 27. At the same time, the new palm insulation fabric 15 rotates to the designated position and fits with the backhand insulation fabric 11. Finally, insert the fingers into the new insulating finger sleeves 16 in sequence to achieve the effect of quickly replacing the palm insulation fabric 15 and the insulating finger sleeves 16.

[0070] Embodiment 2:

[0071] As Figure 12 shown, a wearing method of an insulating isolation and protection tool for 0.4 kV low-voltage live working is as follows:

[0072] Those skilled in the art first pass their hands through the wrist insulating fabric 12, then put the fixing strap 17 on the palm and tighten the insulating strap 13. Then, insert the connecting post 22 and the locking pin 23 on the lower connecting piece 21 into the connector housing 24, rotate the palm insulating fabric 15 to drive the connector housing 24 to rotate, so that the locking pin 23 rotates 120° and abuts against the limit block 27. At the same time, the palm insulating fabric 15 rotates to the specified position and fits with the backhand insulating fabric 11. Finally, insert the fingers into the insulating finger sleeves 16 in turn; when working at height, when the outer insulating layer 151 on the surface of the palm insulating fabric 15 or the insulating finger sleeve 16 wears or breaks, the internal current induction layer 152 will conduct the current signal to the current induction unit 10. After the current induction unit 10 senses the current, it lights up the warning light 14 to prompt the user that the insulating glove is damaged; then the user moves the palm to the abdomen, inserts the magnetic protrusion 28 on the old palm insulating fabric 15 into the front positioning cover 30 of the front buckle 32. The front positioning cover 30 is engaged with the magnetic protrusion 28 to fix the old palm insulating fabric 15. Then rotate the palm to drive the locking pin 23 to rotate reversely 120° and disengage from the slot 26, so that the connecting post 22 is separated from the connector housing 24; finally, move the palm to the waist side, insert the connecting post 22 and the locking pin 23 on the connecting piece 21 into the connector housing 24 of the new palm insulating fabric 15 in the side hanging box 33, rotate the palm insulating fabric 15 to drive the connector housing 24 to rotate, so that the locking pin 23 rotates 120° and abuts against the limit block 27. At the same time, the new palm insulating fabric 15 rotates to the specified position and fits with the backhand insulating fabric 11. Finally, insert the fingers into the new insulating finger sleeves 16 in turn to complete the wearing.

[0073] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
