Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1 to 4, a multipurpose chain link type electric power security fence comprises a plurality of chain links 1, wherein adjacent chain links 1 are hinged, one end of each chain link 1 is provided with a slot, the other end of each chain link 1 is provided with an inserted rod matched with the slot of the adjacent chain link 1, the inserted rod is provided with a connecting hole 8, the slot is provided with a connecting threaded hole 9, the slot is connected with the inserted rod through a connecting screw 3-1 inserted into the connecting hole 8 and the connecting threaded hole 9, the chain link 1 is inserted with an upright rod 2 or a horizontal ladder rod 4-1, the chain link 1 is provided with a left-handed threaded hole 2-1, the hole of the left-handed threaded hole 2-1 is provided with a notch 2-2, the lower part of the upright rod 2 is provided with a first positioning screw 7 matched with the notch 2-2, the middle part of the horizontal ladder rod 4-1 is provided with, when the vertical rods 2 are inserted into the chain links 1, the lower parts of the vertical rods 2 are inserted into the chain links 1, the upper parts of the vertical rods 2 are symmetrically hinged to two connecting cross rods 3, the upper parts of the vertical rods 2 are connected with lug seats 5, the two connecting cross rods 3 are symmetrically hinged to the lug seats 5, the free ends of the connecting cross rods 3 are provided with magnets 6 capable of connecting the connecting cross rods 3 of the two adjacent vertical rods 2 together, the top parts of the vertical rods 2 are provided with warning lamps 4, the warning lamps 4 are solar red rotary warning lamps, red and white alternate fluorescent colors are coated on the vertical rods 2 and the connecting cross rods 3, when the horizontal ladder rods 4-1 are inserted into the chain links 1, the horizontal ladder rods 4-1 are inserted into the chain links 1 in a penetrating mode, and the middle parts of the horizontal ladder rods 4-1 are fixed.
As shown in fig. 5, the multi-section chain link 1 can be folded into any shape (can form an N-edge shape) after being assembled together, thereby satisfying the construction isolation requirement of any special region and forming a closed whole. When the straight line section is used, every other section is required to be folded into a triangular shape to serve as an upright post of the fence, so that the overall stability of the fence is improved.
As shown in fig. 6, after the multi-section chain links 1 are assembled together, a climbing ladder can be formed by matching with the cross ladder rod 4-1, and the climbing ladder is convenient to be applied to construction sites such as electric vertical shafts and channels (climbing areas).
The present invention will be described in further detail with reference to specific embodiments below:
firstly, according to the requirement of a required power production construction site, assembling a chain link base meeting the requirement of a construction site area on length. The chain link base is formed by connecting chain links 1 end to end in series and fixedly connecting the chain links in series by connecting screws 3-1 and then inserting upright rods 2. A first positioning nail 7 on the upright rod 2 is aligned with a notch 2-2 on the chain link 1 and is placed into the left-handed threaded hole 2-1, and the upright rod 2 is screwed into place by rotating left. When the device is disassembled, the upright rod 2 can be taken down by rotating the upright rod 2 right to align with the notch 2-2. Open the horizontal pole 3 of connecting on two adjacent pole settings 2, connect horizontal pole 3 and can rotate in the ear seat 5 on pole setting 2, owing to connect 3 ends of horizontal pole and be equipped with magnet 6, make the horizontal pole 3 interconnect of connecting of two adjacent pole settings 2 together, accomplish the whole equipment of chain link formula electric power security fence.
