Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in figure 1, figure 2, figure 3, figure 4, an anti-bird apron that is used for transmission line angle steel tower wire hanging point department, including well apron 1 and symmetry set up left apron 2 and right apron 3 in well apron 1 both sides, left apron 2, well apron 1 and right apron 3 are the components of a whole that can function independently structure and are the arc of tile form, and the inner panel face of left apron 2, well apron 1 and right apron 3 all welds the block tongue 4 that the vertical direction was arranged, and block tongue 4 is located between the angle steel 10 is pieced together to the hanging line, and the bottom of block tongue 4 is equipped with forms fixed bolt 5 with angle steel 10 is pieced together to the hanging line. In this embodiment, because the left cover plate 2 and the right cover plate 3 cover the gusset plates of the angle steel tower, the end sizes of the left cover plate 2 and the right cover plate 3 are slightly larger, that is, the orthographic projections of the left cover plate 2 and the right cover plate 3 in the horizontal plane are both in a T shape, the specific sizes thereof are adjustable according to lofting, and the gusset plates are required to be basically covered.
Furthermore, the latch tongue 4 comprises a first steel plate 41 and a second steel plate 42 which are arranged in parallel, the distance between the outer side surfaces of the first steel plate 41 and the second steel plate 42 is matched with the distance between the vertical limbs of the hanging wire double-spliced angle steel 10, and the bolt 5 is connected with the first steel plate 41 and the second steel plate 42. As shown in fig. 5, under normal conditions, the hanging-line double-spliced angle steel 10 is installed upward, and at this time, the position of the bolt 5 should be lower than the lower surface of the horizontal limb of the hanging-line double-spliced angle steel 10, that is, the latch 4 needs to extend out of the lower portion of the horizontal limb of the hanging-line double-spliced angle steel 10, so that the bolt 5 can form an abutting joint with the lower surface of the horizontal limb of the hanging-line double-spliced angle steel 10 after penetrating through the first steel plate 41 and the second steel plate 42, and plays a role in fixing. As shown in figure 6, when the double angle steel 10 is installed downwards, the bolt 5 is positioned lower than the lower surface of the vertical limb of the double angle steel 10 and is fixed by the bolt 5. In this embodiment, two sets of locking tongues 4 are respectively arranged on the left cover plate 2, the middle cover plate 1 and the right cover plate 3, the length of the locking tongues 4 is determined according to the size of the hanging double-pin angle steel 10 and the orientation lofting of limbs, and the arrangement position of the locking tongues 4 should be avoided from the wire fittings on the angle steel tower.
Furthermore, gaps are respectively reserved between the middle cover plate 1 and the left cover plate 2 and between the middle cover plate and the right cover plate 3, and the gaps are 10 mm. The function of leaving gaps is to ventilate and to move conveniently during maintenance.
Furthermore, the outer side end faces of the left cover plate 2 and the right cover plate 3 are respectively provided with a sealing plate 6.
The utility model discloses an apron is in-service use, mainly in order to reduce birds possibility of nesting at the end to the atress component, the tower factory can change concatenation or non-circular arc face into according to the convenient principle of processing, nevertheless need ensure to install the fastening. If during the installation, when apron and angle steel, bolt take place to interfere, can guarantee the apron and can laminate the installation with the apron opening of interfering department.
The beneficial effects of the utility model reside in that: 1) the top surface of the arc-shaped cover plate can reduce the probability of long-term retention of birds and can prevent bird droppings from falling on the insulator string; 2) the left cover plate, the middle cover plate and the right cover plate are designed in a split manner, so that the front and back movement and the convenient disassembly can be realized; 3) when the cover plate is additionally arranged in the later period, the stress of the whole structure of the iron tower is not influenced, and the method can be effective in the whole life cycle of the iron tower; 4) greatly reduce the working strength of later operation and maintenance of the line, greatly reduce the expenditure of bird-preventing cost, improve the working quality and have great economic and social benefits.
