The barrier warning belt is usually built in two modes, one mode is a floor mode, is similar to a bank isolation fence and consists of at least two floor type supports, has the advantages of simple building and capacity of being placed on the ground, and has the defects of large volume, heavy weight and difficulty in carrying; the other is of a binding type, which has the advantages that no supporting object is carried, and the disadvantage that the binding is required by a field fixture. Because convenient to carry, the warning area is put up to the mode that present outdoor electric power operation generally used the ligature to tie.
At present, 6-35kV high-voltage switch cabinets which are used in a large amount are not specially designed with binding fixing pieces which are necessary for building the blocking warning belt, so that an operator needs to find a column, a handle and other fixing pieces which are suitable in height and distance on site and can bind the blocking warning belt. However, since the environments around each high-voltage switch cabinet are different, it is difficult to find a stable binding fixture with a suitable height, and sometimes the binding fixture needs to be built by nailing or driving expansion bolts on the wall surface. If the time spent on building a reliable binding fixture is too long, power supply will be affected; if an unreliable fixture is bound with the barrier, the barrier warning tape is easy to fall off, so that the safety guarantee cannot be achieved, and personal casualty accidents can be caused.
Therefore, a fast setting-up device of the barrier warning belt, which is universal on various high-voltage switch cabinets in operation fields, firm, reliable and convenient to carry, is urgently needed to be designed.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
In the high-voltage switch cabinet overhaul site, the environments around the high-voltage switch cabinet are different, so that the finding of a stable and reliable binding fixture with proper height is difficult, but almost all the high-voltage switch cabinets, peripheral cabinet bodies and doors and windows are made of iron, and the relatively stable condition can be utilized.
Example 1:
a device for quickly building a barrier warning belt 5 for an electric power overhaul field comprises a square frame 1, wherein a swinging body 2 is arranged in the frame 1, and the surface 21 of the swinging end of the swinging body 2 is an arc surface. The swinging body 2 is rotatably connected with the frame 1 through a rotating shaft 3, the axis of the rotating shaft 3 is parallel to the inner side surface of the frame 1, and the minimum gap between the arc surface of the swinging body 2 and the inner side surface of the frame 1 is smaller than the thickness of the shielding warning belt 5. Usually the minimum clearance between the oscillating end surface of the oscillating body 2 and the inner side surface of the frame 1 is 0.3-0.6 times the thickness of the obscuration warning band, in this embodiment the thickness of the obscuration warning band 5 is between 1-1.2mm and the minimum clearance between the arc surface of the oscillating body 2 and the inner side surface of the frame 1 is 0.5 mm.
Since the swinging body 2 can swing freely in the square frame 1, the barrier warning tape 5 can be inserted into a gap between the swinging end of the swinging body 2 and the frame 1. After the shielding warning belt 5 with a certain length is inserted, the shielding warning belt 5 is pulled back, and under the driving action of the pulling back force, the swinging body 2 swings close to the frame 1, so that the arc surface of the swinging body 2 and the inner side surface of the frame 1 form a clamping surface for clamping the shielding warning belt 5. The clamping surface is similar to a cam pressing mechanism and has the characteristics of unidirectional self-locking pressing and reverse easy unlocking. The larger the pull-back force is, the larger the self-locking force is generated, and when unlocking is performed, the smaller pulling force is only required to be applied to the end of the barrier warning belt 5 to unlock the barrier warning belt 5.
A magnet 4 is arranged at the bottom of the frame 1, and the magnet 4 is a neodymium iron boron strong magnet. Magnet 4 can be inhaled on high tension switchgear, or peripheral cabinet body, door and window fast magnetism, and the height of absorption can be adjusted wantonly to the position of distance.
During maintenance work, as shown in fig. 2, at least two building devices are needed according to the field environment. One building device is magnetically attracted on the high-voltage switch cabinet, and the other building device is magnetically attracted on an adjacent cabinet body; one end of the barrier warning belt 5 is inserted into a gap of one of the building devices, and the lock is pulled back to be locked; then the other end of the obscuration warning band 5 is inserted into a gap of another building device, after the appropriate length is pulled, the obscuration warning band 5 is pulled back, and the other building device is locked, so that the building of the obscuration warning band 5 is completed. When the shielding warning belt 5 is removed, the shielding warning belt 5 outside the pair of building devices is pulled, and then the removal of the shielding warning belt 5 can be completed.
If the length of the blocking warning belt 5 is too long and is far longer than the required warning length, a certain time is consumed for pulling the blocking warning belt 5, so that the technical scheme is further improved, the frame 1 is provided with an insertion hole 11 for the blocking warning belt 5 to be inserted into the clamping surface from the lateral direction, the blocking warning belt 5 with the proper length is pulled, and then the blocking warning belt is inserted into the gap from the lateral direction of the insertion hole 11, and the building time can be further saved.
As is easy to see, the construction device solves the construction problem of the barrier warning belt 5 in a simple magnetic attraction mode without searching for a stable binding fixture with proper height, distance and distance on the overhaul site; in addition, this device of building can realize blocking warning area 5 fast and press from both sides tight fixed with demolish, compares traditional tying up the mode, has quick, reliable advantage.
Example 2:
in the building apparatus according to embodiment 1, since the insertion opening 11 is provided in the square frame 1, the strength of the frame 1 is reduced, and the frame 1 is easily deformed by a force applied to one arm thereof in the process of clamping the barrier warning tape 5. In addition, the neodymium iron boron strong magnet has strong magnetic attraction, is relatively laborious to disassemble, and the stress condition of the frame 1 is not good.
For this reason, the technical solution is further improved, as shown in fig. 3, the present embodiment is different from embodiment 1 in that:
first, a hook 6 is rotatably connected to one side of an insertion opening 11 of the frame 1, and a pin 7 hooked to the hook 6 is fixedly connected to the other side of the insertion opening 11. After the hook 6 is hooked with the pin shaft 7, the tensile strength of the square frame 1 on the side of the insertion opening 11 is enhanced, and the stress condition of the square frame 1 is improved. Since the hook 6 can be hooked to and unhooked from the pin 7, the insertion and extraction of the obscuration warning band 5 from the insertion port 11 is not hindered.
Second, the magnet 4 is a rotatable magnet that is similar in structure to a magnetic meter base. The knob is arranged on the rotatable magnet, when the knob is positioned at a certain angle, the rotatable magnet has no magnetism outwards, and when the knob rotates by 90 degrees, the rotatable magnet has magnetism outwards. Thus, labor is saved when the device is disassembled, installed and adjusted.
The details of which are not described in the prior art. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
