Example (b):
a combined cross arm shielding device comprises a head shielding shell 4, a middle shielding shell and a tail shielding shell 6, wherein the head shielding shell 4, the middle shielding shell and the tail shielding shell 6 are sequentially connected to form an integral shielding shell, and the integral shielding shell covers a cross arm and is supported by the cross arm, so that the shielding of the cross arm is realized.
The middle shielding shell comprises a plurality of unit shielding shells 5, as shown in fig. 1 and 2, the vertical sections of the unit shielding shells 5 are in an inverted U shape, one end face of each unit shielding shell 5 is provided with an inserting column 1, the other end face of each unit shielding shell is provided with an inserting hole 2, and the size of each inserting column 1 is not larger than that of each inserting hole 2. The unit shielding shells 5 are assembled, and the assembling of a plurality of unit shielding shells 5 is realized by inserting the inserting columns 1 of one unit shielding shell 5 into the inserting holes 1 of another unit shielding shell 5.
As shown in fig. 2 and 5, the top surfaces of the two ends of the unit shielding shell 5 are respectively provided with outward semicircular openings 3 with the same size, the top surface of the unit shielding shell 5 is movably provided with a baffle 12, the baffle 12 is in an inverted U shape, the two outer side surfaces of the unit shielding shell 5 are respectively provided with a sliding groove 13, and the two side edges of the baffle 12 are respectively folded inwards and accommodated in the two sliding grooves 13 and can move in the sliding grooves 13. It should be noted that the length of the unit shielding case 5 is not less than the sum of the length of the baffle 12 and the diameter of the semicircular opening 3.
When the device is assembled for use, the two opposite semicircular openings 3 form a circular opening. 13 both ends of spout are the opening design for when two units shield shell 5 and link together, spout 13 on two units shield the shell meets, therefore baffle 12 can stride across two units and shield shell 5, in order to shelter from circular opening, through moving a plurality of baffles 12 respectively to rather than adjacent circular opening part with the syntropy, thereby realize sheltering from a plurality of circular openings after the equipment. The opening and closing state of the circular opening is controlled by selecting whether the shutter 12 moves to block the circular opening. The circular opening is opened so that the insulator can penetrate out for shielding the cross arm at the insulator mounting position, and the circular opening is closed so as to well shield the cross arm between the insulator intervals. The cross arm provided with insulators with different numbers is well shielded by selecting the opening state and the closing state of the plurality of circular openings.
Further, in order to fix the baffle 12 when the baffle 12 is required to be fixed, as shown in fig. 1, fig. 2 and fig. 5, the top surface of the unit shielding shell 5 is provided with a limiting strip 7, one end of the baffle 12 abuts against the limiting strip 7, bayonets 8 are respectively arranged on two surfaces of the limiting strip 7 facing the two semicircular openings 3, soft insulating layers are arranged on the inner surfaces of the bayonets 8, and the baffle 12 can be tightly clamped into the bayonets 8 under stress, so that the baffle 12 is fixed. Specifically, when the device is assembled and used, the baffle 12 is tightly clamped with the corresponding limiting strip 7 of the round opening in an open state; for the circular opening in the closed state, the shutter 12 is caught by the stopper 7 of the corresponding other unit shielding case 5.
The shielding length can be adjusted by adjusting the depth of the inserting column 1 into the inserting hole 2, so that the shielding length between the insulator intervals can be adjusted according to the difference of the insulator interval distances when the device is assembled and used, and the applicability of the cross arm shielding device is further improved. In order to avoid the change after the shielding length is adjusted, as shown in fig. 3 and 5, a groove 10 is formed on the outward surface of the insert column 1 in the length direction of the unit shielding shell 5, and a soft insulating plug 11 is connected to the unit shielding shell 5.
