Description

Technical Field

[0001] The invention relates to the technical field of electric wire hooks, in particular to a portable temporary electric wire safety harness. Background Art

[0002] There are many electrical equipment during the construction process at the construction site, but the operating environment at the construction site is very simple, and the situation is constantly changing during the construction process. Many wires are temporarily installed, and the wires are dragged around at will. If the insulation layer of the dragged wires is damaged by friction, very serious safety accidents will occur. In order to eliminate this safety hazard, the wires need to be overhead.

[0003] The current wire hooks are generally in direct contact with the wires, making it difficult to hang and fix the wires with the wire hooks. Moreover, when the wires are subjected to external forces, they will rub against the wire hooks, causing damage to the wires. At the same time, the existing wire hooks have no other functions. When a fire occurs in the circuit, manual fire extinguishing is required, but manual fire extinguishing takes a long time. Failure to extinguish the fire in time will result in serious economic losses. Summary of the Invention

[0037] Among them, Figure 4 As shown, the lifting and adjusting groove 8 is composed of two groups of horizontal sections, one group of ascending sections and one group of descending sections, and the ascending section of the lifting and adjusting groove 8 includes a first ascending vertical section, an ascending inclined section and a second ascending vertical section, and the descending section includes a descending vertical section and a descending inclined section, and the first ascending vertical section is connected with the descending inclined section away from the descending vertical section through a group of horizontal sections, the first ascending vertical section and the descending vertical section are on the same vertical line, and the second ascending vertical section is connected with the descending vertical section through another group of horizontal sections, and a gap is opened on the side adjacent to the second ascending vertical section and the descending vertical section.

[0038] In this embodiment, when the limiting column 11 moves inside the lifting adjustment slot 8, when the limiting column 11 moves to the second rising vertical section, under the action of the torsion spring, the limiting column 11 will enter the notch, at this time the limiting column 11 can stop, and continue to move the limiting column 11 to the top of the second rising vertical section, the limiting column 11 will naturally deflect to the descending vertical section, and then automatically return to the bottom of the first vertical section, and the position adjustment of the connecting plate 2 and the hook 3 will be completed during the movement of the limiting column 11

[0039] In this embodiment, two groups of semicircular arc parts 14 form a circular ring, and one of the two groups of semicircular arc parts 14 is fixedly connected to the front end surface of the connecting plate body 9 through a fixing block 17, and the semicircular arc parts 14 fixed to the connecting plate body 9 are preferably the group located below the circular ring, and the wire can be coiled by the two groups of semicircular arc parts 14.

[0040] Specifically, the fixing block 17 is slidably connected inside the positioning groove 7, and the size of the limiting groove 18 is adapted to the limiting column 5. The limiting column 5 passes through the limiting groove 18 to connect the two groups of semicircular arc parts 14 together.

[0041] In this embodiment, the supporting and protecting mechanism 16 includes a flexible fixing plate 19 , a first sealing sleeve 20 and a second sealing sleeve 21 are fixedly connected to the lower end surface of the flexible fixing plate 19 , and the second sealing sleeve 21 is between the flexible fixing plate 19 and the first sealing sleeve 20 .

[0042] Specifically, the first sealing sleeve 20 and the second sealing sleeve 21 are both plastic films, and the side adjacent to the second sealing sleeve 21 and the flexible fixing plate 19 is filled with carbon dioxide, and the side adjacent to the first sealing sleeve 20 and the second sealing sleeve 21 is filled with fire extinguishing powder. The fire source of the line can be extinguished by carbon dioxide and fire extinguishing powder.

[0043] Furthermore, a layer of heat shrink film is provided on the side of the first sealing sleeve 20 facing away from the flexible fixing plate 19 .

[0044] Working principle: When in use, the cable tie is fixed to the specified position by bolts, and then the wires are placed on a group of semi-circular parts 14, and then the two groups of semi-circular parts 14 are merged, and the wires are coiled by the two groups of semi-circular parts 14, and then the position of the connecting plate 2 and the hook 3 is adjusted so that the limiting column 5 passes through the limiting groove 18 on the two groups of semi-circular parts 14, so that the two groups of semi-circular parts 14 are fixed, and at the same time, the position of the limiting column 11 inside the lifting adjustment groove 8 is fixed to determine the position of the wires. In the event of a fire, the support and protection mechanism 16 shrinks due to heat, and the air pressure inside the support and protection mechanism 16 increases. When the air pressure reaches the threshold, the fire extinguishing powder and carbon dioxide inside the support and protection mechanism 16 will explode together to extinguish the flame. When the flame is small and cannot reach the air pressure threshold, the heat shrink film outside the first sealing sleeve 20 will be carbonized due to single-point heating for too long, and carbon dioxide and fire extinguishing powder will also explode to extinguish the flame.

At the same time, the first sealing sleeve 20 and the second sealing sleeve 21 are both plastic films. After being filled with carbon dioxide and fire extinguishing powder, the supporting and protecting mechanism 16 bulges, so that after the two sets of semicircular arc members 14 wrap the wire coil, the supporting and protecting mechanism 16 is opened. The flexible structure of the first sealing sleeve 20 is used to limit the position of the wires, and the limit is coordinated, so that the wires have a certain swing space to prevent the wires from being damaged by friction. At the same time, a layer of heat shrink film is provided on the side of the first sealing sleeve 20 away from the flexible fixing plate 19, so that when the wires catch fire, the temperature rises and the heat shrink film outside the first sealing sleeve 20 shrinks, and the pressure on the supporting protection mechanism 16 increases. After reaching the threshold, the first sealing sleeve 20 and the second sealing sleeve 21 rupture, and the instantaneous high-pressure carbon dioxide will burst out together with the fire extinguishing powder to extinguish the fire, greatly improving the safety of the line.
