Referring to fig. 1-3, a novel optical fiber automatic contraction device comprises an antenna rotating shaft 1, a bottom support 2 is installed at the bottom of the antenna rotating shaft 1, the antenna rotating shaft 1 and the bottom support 2 are both installed with a lower building, one side of the bottom support 2 is far away from the antenna rotating shaft 1, a C-shaped support 3 is installed on the top wall of the bottom support, an optical slip ring 5 is rotatably installed on the C-shaped support 3, an optical fiber rotary table 4 is fixedly installed on the outer side of the optical slip ring 5, a spring bin 6 is installed on the upper side of the C-shaped support 3, an access wire 9 is installed at the bottom end of the optical slip ring 5, an output optical fiber 10 is wound on the optical fiber rotary table 4, a sleeve 7 is sleeved on the outer side of the antenna rotating shaft 1, the sleeve 7 is installed with an upper building through a hanger rod 8, a connecting hole 11 is formed in the sleeve 7, and one end of the output optical fiber 10 is fixed in the connecting hole 11;
the total length of the output optical fiber 10 is 30 meters, and the output optical fiber comprises a blue line body with 20 meters at the front section, a yellow line body with 5 meters at the middle section and a red line body with 5 meters at the rear section.
The antenna rotating shaft 1 rotates along with the antenna, the bottom support 2 is fixed with the antenna rotating shaft 1, and the bottom support 2 rotates along with the antenna rotating shaft 1. The C-shaped support 3 and the fiber turret 4 both rotate with the bottom support 2 and both rotate around the ferrule 7. For example, when the antenna spindle 1 rotates in the forward direction, the output optical fiber 10 can be unwound from the antenna turntable 4 and gradually wound around the sleeve 7, and when the antenna spindle 1 rotates in the reverse direction, the output optical fiber 10 can be rewound on the optical fiber turntable 4.
The signal is accessed from the access line 9, is switched to the output optical fiber 10 through the optical slip ring 5, and is accessed to the superstructure through the connecting hole 11.
The optical slip ring 5 comprises a shaft rod 12, the shaft rod 12 and the C-shaped support 3 are rotatably installed, a conductive slip ring 13 is sleeved on the outer side of the shaft rod 12, the lower side of the conductive slip ring 13 is electrically connected with the access wire 9, the outer side of the conductive slip ring 13 is in sliding contact with a connecting contact 14, and the connecting contact 14 is electrically connected with one end of the output optical fiber 10;
the principle of the optical slip ring 5 is as follows: the incoming line 9 is electrically connected on the conductive slip ring 13, the lead slip ring 13 and the shaft rod 12 rotate along with the rotation of the optical fiber rotary table 4, and the output optical fiber 10 always has sliding contact with the lead slip ring 13 through the connecting contact 14, so that the incoming line 9 can transmit signals to the lead slip ring 13 firstly and then transmit the signals to the output optical fiber 10. Thereby solving the problem that the access wire 9 and the output optical fiber 10 are wound due to the rotation of the optical fiber rotary table 4.
The spring bin 6 comprises a box body 15 and a stainless steel spring belt 16, the box body 15 is fixed on the upper side of the C-shaped support 3, the stainless steel spring belt 16 is located in the box body 15 and is in a spiral shape, one end of the outer side of the stainless steel spring belt 16 is fixed with the inner wall of the box body 15, and one end of the inner side of the stainless steel spring belt 16 is fixed with the shaft rod 12.
As the fiber turret 4 rotates around the ferrule 7, such as shown in fig. 1, as the fiber turret 4 rotates right (counterclockwise) around the ferrule 7, the output fiber 10 may gradually wind up on the ferrule 7, and there is a pulling force on the output fiber 10 from the side of the ferrule 7 that may cause the fiber turret 4 to rotate (which may be considered as spinning) around the shaft 12; when the fiber turn plate 4 rotates leftwards (clockwise) around the ferrule 7, the output fiber 10, which was originally wound outside the ferrule 7, can be rewound on the fiber turn plate 4 because the output fiber 10 is mainly subjected to the reaction force of the stainless steel spring band 16 in the spring bin 6 and thus can be rewound on the fiber turn plate 4.
The sleeve 7 is sleeved on the outer side of the antenna rotating shaft 1, and a gap exists between the inner wall of the sleeve 7 and the outer wall of the antenna rotating shaft 1. The sleeve 7 does not follow the rotation of the antenna shaft 1 when it is rotated.
The output optical fibre 10 is fixed to the ferrule 7 by a port 11 and the output optical fibre 10 is in turn electrically connected to a signal access point in the superstructure. The output optical fiber 10 is not electrically connected to the antenna shaft 1, or is electrically connected to each signal access point in the upper building.
The optical fiber rotary table 4 and the shaft rod 12 are fixed with each other and are rotatably installed at the upper side and the lower side of the C-shaped support 3 through the shaft rod 12.
The bottom of the C-shaped support 3 is provided with a jack, and the access wire 9 penetrates through the jack and is electrically connected with the conductive slip ring 13 in the smooth ring 5.
The bottom of sleeve pipe 7 is formed by two semicircle pipes through the bolt equipment concatenation, and the top of sleeve pipe 7 is two semicircle boards, and two semicircle boards form through the bolt equipment concatenation.
The hanger rod 8 is fixed with the semi-circular plate on the top of the sleeve 7 by screw thread. The sleeve 7 as a whole can be fixed to the superstructure by means of the suspension rod 8 so as not to rotate together with the antenna rotary shaft 1.
The working principle and the using process of the invention are as follows: the antenna rotating shaft 1 and the base support 2 rotate together, and the sleeve 7 is fixed with an upper building, so that the sleeve cannot rotate; when the optical fiber rotating shaft 1 rotates rightwards (anticlockwise) in fig. 1, the optical fiber rotating disc 4 rotates rightwards (anticlockwise) around the sleeve 7 along with the rotation of the antenna rotating shaft 1 and the base support 2, the output optical fiber 10 is gradually wound on the outer side of the sleeve 7, the winding sequence of the output optical fiber 10 is a blue line body, a yellow line body and a red line body, the output optical fiber 10 can pull the optical fiber rotating disc 4 to rotate in the process, and when the optical fiber rotating disc 4 rotates, the stainless steel spring band 16 of the spring bin 6 is driven by the shaft rod 12 to be tightened in the box body 15;
when the red line body part of the output optical fiber 10 starts to be wound, an operator controls the antenna rotating shaft 1 to rotate reversely, and at the moment, the output optical fiber 10 is not acted by the sleeve 7 any more, but is wound on the optical fiber rotating disc 4 again under the reverse acting force of the stainless steel spring band 16 until the winding is finished. The above is a cycle of unwinding and winding of the output optical fiber 10, and the above cycle is repeated.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
