[0019] The present invention provides a railway communication tower monitoring device, such as Figures 1 to 3As shown, it includes a mounting base 100 and a camera 200, and the mounting base 100 is provided with: A shell body, inside of which a transverse partition 101 is installed; A connecting assembly, comprising a rotating seat 102 rotatably mounted on the diaphragm 101, the rotating seat 102 being coaxially provided with a rotating rod 103, the bottom of the rotating rod 103 being rotatably connected to the top of the diaphragm 101, the top of the rotating rod 103 being rotatably passed through the housing and connected to the camera 200, and two long strip-shaped openings 104 being radially oppositely provided on both sides of the rotating seat 102; The driving assembly is installed at the bottom of the diaphragm 101, and includes a rotating gear 105, a first driven gear 106, a second driven gear 107 and a third driven gear 108 that are meshed in sequence. The rotating gear 105 is coaxially provided with a rotating shaft A109. The bottom of the rotating shaft A109 is coaxially fixed with the rotating shaft of a motor 110. The top of the rotating shaft A109 rotates through the diaphragm 101 and is vertically connected to a connecting rod A111. The end of the connecting rod A111 away from the rotating shaft A109 is provided with a support arm A112 extending vertically upward. The third driven gear 108 is coaxially provided with a rotating shaft B113, the bottom of which is rotatably connected to the inner bottom wall of the shell, the top of which rotates through the transverse partition 101 and is vertically connected to a connecting rod B114, and the end of the connecting rod B114 away from the rotating shaft B113 is provided with a support arm B115 extending vertically upward, the rotating gear 105 and the third driven gear 108 rotate forward and reverse respectively, driving the support arm A112 and the support arm B115 to pass through the corresponding openings 104 in turn, pushing the rotating seat 102 to rotate forward and reverse.

[0020] In the present technical solution, the railway communication tower monitoring device is provided with a mounting base 100 and a camera 200. The mounting base 100 is provided with a shell, and a cavity is provided inside the shell. A diaphragm 101 is installed in the cavity. A connecting component is installed above the diaphragm 101, and a driving component is installed below. The connecting component includes a coaxially connected rotating base 102 and a rotating rod 103. The rotating base 102 is rotatably installed on the diaphragm 101, and the rotating rod 103 rotates to pass through the top of the shell. The camera 200 is installed on the top of the rotating rod 103. Two openings 104 that pass through from top to bottom are relatively opened on both sides of the rotating base 102. The opening 104 is in the shape of an elongated strip and extends toward the center of the circle along the radial direction of the rotating base 102. The driving assembly includes a rotating gear 105, a first driven gear 106, a second driven gear 107 and a third driven gear 108 which mesh and rotate in sequence, wherein the rotating gear 105 and the third driven gear 108 are coaxially connected to the rotating shaft A109 and the rotating shaft B113 respectively, the bottom of the rotating shaft A109 is coaxially fixed to the rotating shaft of the motor 110, the bottom of the rotating shaft B113 is rotatably connected to the inner bottom wall of the shell, the tops of the rotating shaft A109 and the rotating shaft B113 both rotate through the cross partition 101 and are vertically connected to the connecting rod A111 and the connecting rod B114 respectively, and the ends of the connecting rod A111 and the connecting rod B114 are vertically connected to the upward extending support arms A112 and B115 respectively. When in use, the motor 110 drives the rotating gear 105 to rotate clockwise, thereby driving the support arm A112 to rotate clockwise, and penetrate into the opening 104 to push the rotating seat 102 to rotate clockwise. At the same time, the third driven gear 108 rotates counterclockwise, driving the support arm B115 to rotate counterclockwise. After the support arm A112 rotates out of the opening 104, the support arm B115 rotates and penetrates into another opening 104 to push the rotating seat 102 to rotate counterclockwise. The reciprocating rotation of the rotating seat 102 realizes the reciprocating swing of the camera 200 on the top of the rotating rod 103. The railway communication tower monitoring device has a reasonable structural design. By arranging a shell to accommodate the connecting assembly and the driving assembly, the structure is made more compact, space is saved, movement and maintenance are convenient, and the service life is increased. By meshing a plurality of gears in sequence, the reciprocating rotation of the camera 200 can be achieved by only one ordinary motor 110, which saves energy. Compared with reciprocating rotating motors, the motor used in the present technical solution has low cost, small vibration, simple structure, long service life, and no need for frequent maintenance or inspection, and is more suitable for use in complex outdoor environments. By adjusting the rotation speed of the rotating gear or adjusting the length of the connecting rod A and the connecting rod B, the swing frequency and positioning time of the camera 200 can be adjusted, thereby improving the flexibility and applicability of the device. By rotating the gear 105 and the third driven gear 108 in opposite directions, the support arm A112 and the support arm B115 are driven to pass through the two openings 104 in sequence, thereby pushing the rotating seat 102 to rotate back and forth together with the camera 200 to expand the monitoring range.Although the prior art uses a reciprocating motor to drive the camera to rotate back and forth, the reciprocating motion is uninterrupted, making it difficult for the camera to be positioned at a certain place for a period of time, affecting the monitoring camera effect.

[0021] In another technical solution, the first driven gear 106 and the second driven gear 107 are both coaxially fixed with a rotation axis C, and the tops of the two rotation axes C are rotatably connected to the bottom of the diaphragm 101. In this technical solution, the first driven gear 106 and the second driven gear 107 are installed at the bottom of the diaphragm 101 to improve structural stability.

[0022] Preferably, the diameters of the rotating gear 105 and the third driven gear 108 are the same, the lengths of the connecting rod A111 and the connecting rod B are the same, and the lengths of the two are greater than the radial length of the opening 104. The bottom surface of the rotating seat 102 is higher than the top surfaces of the connecting rod A111 and the connecting rod B114, and the width of the opening 104 is greater than the diameters of the supporting arms A112 and the supporting arms B115. In this technical solution, the connecting rod A111 and the connecting rod B114 are lower than the rotating seat 102, and the rotation of the three does not affect each other, ensuring that the supporting arms A112 and B115 can smoothly penetrate into the two openings 104, thereby driving the rotating seat 102 to rotate smoothly.

[0023] Preferably, the rotation axis A109 and the rotation axis B113 are symmetrically arranged on both sides of the rotating seat 102. In the present technical solution, the rotation axis A109, the rotation axis B113 and the center of the rotating seat 102 are located on the same straight line, so that the two arms can smoothly penetrate into the corresponding openings 104, and the reciprocating rotation displacement of the rotating seat 102 is consistent, thereby improving the structural stability.

[0024] Preferably, a plurality of balls are arranged around the outer periphery of the support arm A112 and the support arm B115. In the present technical solution, a plurality of balls are arranged so that the two support arms can smoothly penetrate into the corresponding openings 104, thereby improving the smoothness of rotation.

[0025] Preferably, the support arm A112 and the support arm B115 are parallel to the rotating rod 103. In the present technical solution, the support arm A112, the support arm B115 and the rotating rod 103 are perpendicular to the rotating seat 102 and extend vertically upward, so that the two support arms can smoothly pass through the corresponding openings 104 and push the rotating seat 102 to rotate.

[0026] Preferably, a mounting plate 116 is provided on one side of the mounting seat 100, and an extension portion is provided at the top and bottom of the mounting plate 116 beyond the housing, and the extension portion is provided with a plurality of mounting holes 117. In this technical solution, bolts are screwed into the mounting holes 117 to fix the mounting plate 116 together with the mounting seat 100 to one side of the communication tower, thereby improving the installation stability.

[0027] Preferably, the axis of the rotating shaft A109, the rotating shaft B113 and the rotating rod 103 are located on the same plane, the centers of the rotating gear 105, the first driven gear 106, the second driven gear 107 and the third driven gear 108 are located on the same straight line, and the rotating gear 105 is close to the mounting plate, and the third driven gear 108 is far away from the mounting plate. In this technical solution, the plane where the centers of the rotating gear 105, the first driven gear 106, the second driven gear 107 and the third driven gear 108 are located is perpendicular to the mounting plate, so that the camera 200 swings left and right in the direction facing away from the mounting plate and the communication tower to prevent the monitoring field of view from being blocked by the communication tower.

[0028] Preferably, the motor 110 is a stepper motor. In this technical solution, the electric pulse signal of the stepper motor is used to drive the rotating gear 105 to rotate intermittently, and the fixed-point dwell time of the camera 200 can be adjusted according to demand.

[0029] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
