[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] like Figs. 1-2 As shown, the present invention discloses a power transmission line channel protection alarm system, including a controller, a utility pole, and a mounting block 1 installed at the utility pole. The mounting block 1 is equipped with a camera and an alarm. A sound cavity 11 is formed inside the mounting block 1. The structure of the sound cavity 11 is consistent with that of a whistle. An air duct 12 is formed on the side of the mounting block 1, which communicates with the sound cavity 11. A drainage hole 13 is formed at the bottom of the sound cavity 11, which communicates with the outside of the mounting block 1.

[0025] In the existing technology, birds can threaten the normal use of power transmission lines, especially in wooded mountains and forests where birds have a suitable living environment and reproduce quickly. The main causes of tripping caused by birds are bird droppings flashover, short circuits in bird nest materials, short circuits during bird flight, and birds pecking at composite insulators. Among these, tripping caused by bird droppings is the main cause of tripping due to bird damage.

[0026] Accordingly, this invention creates a sound cavity 11 on the mounting block 1, and uses a camera to monitor the number and types of birds around the utility pole. When a significant bird threat is detected, an alarm is triggered to alert staff. When wind enters the sound cavity 11 through the air duct 12, the air vibrates within the sound cavity 11, producing a sound that frightens the birds and drives them away. The drainage hole 13 is used to promptly drain water that enters the sound cavity 11 during rainy days, ensuring the normal operation of the sound cavity 11. This reduces the threat of birds to power transmission lines, decreases the occurrence of bird droppings flashover, short circuits in bird nest materials, bird flight short circuits, and bird pecking at composite insulators, and lowers the maintenance costs of power transmission lines.

[0027] In one embodiment of the present invention, the diameter of the air duct 12 near the outer side of the mounting block 1 is larger than the diameter of the air duct 12 near the sound cavity 11. During operation, the larger diameter of the air duct 12 near the outer side of the mounting block 1 facilitates the entry of air into the sound cavity 11 through the air duct 12, while slowing down the speed at which air flows out of the sound cavity 11. This improves the sound emission effect within the sound cavity 11, enabling the repelling of birds even in low wind conditions, thereby reducing the threat of birds to power transmission lines.

[0028] As one of the embodiments of the present application, the bottom of the mounting block 1 is rotationally connected with a rotating rod 2; the rotating rod 2 is circumferentially fixed with a fan blade 21; the rotating rod 2 is further fixed with a ribbon 22; during operation, the fan blade 21 is arranged to rotate the rotating rod 2 when the fan blade 21 is blown, so that the rotating rod 2 drives the ribbon 22 to rotate, and the ribbon 22 drives away the birds, thereby improving the effect of driving away the birds and reducing the possibility of the birds causing damage to the power transmission line.

[0029] As one of the embodiments of the present application, the ribbon 22 is fixed with a metal ball 23 at one end away from the rotating rod 2, and the bottom of the mounting block 1 is fixed with a reed 24 at a position corresponding to the metal ball 23; during operation, the reed 24 is arranged to make the metal ball 23 knock the reed 24 to emit a sound to drive away the birds when the ribbon 22 rotates, thereby improving the effect of driving away the birds and reducing the possibility of the birds causing damage to the power transmission line.

[0030] As one of the embodiments of the present application, the reed 24 is provided with at least two reeds with different thicknesses; during operation, the different reeds 24 are arranged to make the metal ball 23 emit different tones when knocking the different reeds 24, so as to prevent the birds from being insensitive or easily adapting to the same tone, thereby improving the effect of driving away the birds, reducing the possibility of the birds causing damage to the power transmission line, and reducing the maintenance cost of the power transmission line.

[0031] As one of the embodiments of the present application, the drainage hole 13 is provided with a floating block 131 at one side in the sound cavity 11; the bottom of the floating block 131 is provided with a limiting rod 132; the limiting rod 132 is located in the drainage hole 13, and the diameter of the limiting rod 132 is smaller than that of the drainage hole 13; during operation, the floating block 131 is arranged to block the drainage hole 13 when air enters, so as to prevent the air from flowing out of the drainage hole 13, thereby improving the sound emitting effect in the sound cavity 11; when water enters the sound cavity 11, the floating block 131 can float on the water surface, so that the drainage hole 13 is opened, and the water flows out of the drainage hole 13; after the water flows out, the floating block 131 covers the drainage hole 13 again; the limiting rod 132 is arranged to limit the floating block 131, so that the floating block 131 can accurately cover the drainage hole 13 along the direction in which the limiting rod 132 extends into the drainage hole 13.

[0032] As one of the embodiments of the present application, the electric pole is provided with a roller 3 or a roller 3 and a motor, and the two adjacent electric poles are drivingly connected with a belt 31, one of the rollers 3 is fixedly connected with the output shaft of the motor, and the mounting block 1 is fixedly connected below the belt 31; in operation, the motor is controlled by the controller to drive the roller 3 connected with the motor to rotate, so that the belt 31 is driven to transmit between the two rollers 3, thereby driving the mounting block 1 to move between the two adjacent electric poles, and when the mounting block 1 moves from one electric pole to another electric pole, the motor is reversed by the controller, so that the mounting block 1 moves in the opposite direction, thereby realizing reciprocating movement between the two electric poles, so that the camera can monitor a larger range, and the mounting block 1 can drive away the birds in a larger range, reducing the possibility of damage to the power transmission line by the birds.

[0033] As one of the embodiments of the present application, the lower end of the rotating rod 2 is provided with a blade 4; in operation, the blade 4 is driven to rotate when the rotating rod 2 rotates, so that the blade 4 trims the branches and leaves of the trees near the power transmission line, preventing the trees from growing too high to break the power transmission line, improving the protection effect of the power transmission line, and reducing the maintenance cost of the power transmission line.

[0034] As one of the embodiments of the present application, the blade 4 is rotatably connected with the rotating rod 2, and the blade 4 is transitionally connected with the rotating rod 2; in operation, the blade 4 is rotatably connected with the rotating rod 2, and due to the friction between the blade 4 and the rotating rod 2, the rotating rod 2 drives the blade 4 to rotate when rotating, and when the branches are thicker and the resistance to the blade 4 is larger, the blade 4 is blocked and stops rotating, and contacts with the branches, and the blade 4 cuts the branches when the mounting block 1 moves, thereby reducing the possibility of damage to the blade 4 when it swings and chops thicker branches, and improving the service life of the blade 4.

[0035] As one of the embodiments of the present application, one end of a torsional spring 41 is fixedly connected with the rotating rod 2, and the other end of the torsional spring 41 is fixedly connected with the blade 4; in operation, the torsional spring 41 supports the blade 4 when the blade 4 is blocked by thicker branches, so that the blade 4 has a force to abut against the branches, and the blade 4 is in close contact with the branches, thereby improving the cutting effect of the blade 4 on thicker branches.

[0036] The specific working process is as follows:

[0037] The number and species of birds around the electric pole are monitored by the camera, and when the bird threat is detected, the alarm sends a warning to the staff. When the wind enters the sound cavity 11 through the air duct 12, the air vibrates in the sound cavity 11 and makes a sound, making the birds feel scared and achieving the purpose of driving away the surrounding birds. The drain hole 13 is used to drain the water in the sound cavity 11 in rainy days, so that the sound cavity 11 works normally. The diameter of the air duct 12 near the outside of the mounting block 1 is larger than the diameter of the air duct 12 near the sound cavity 11, which facilitates the air entering the sound cavity 11 through the air duct 12 and slows down the speed of the air flowing out of the sound cavity 11. By setting the fan blade 21, when the fan blade 21 is blown, the fan blade 21 drives the rotating rod 2 to rotate, so that the rotating rod 2 drives the ribbon 22 to rotate, and the ribbon 22 drives the birds away. By setting the reed 24, when the ribbon 22 rotates, the metal ball 23 strikes the reed 24 to make a sound to drive away the birds. By setting different reeds 24, the metal ball 23 makes different sounds when it strikes different reeds 24, preventing birds from being insensitive or easily adapting to the same sound. By setting the float 131, when the air enters, the float 131 blocks the drain hole 13 to prevent air from flowing out of the drain hole 13, thereby improving the sound effect in the sound cavity 11. When water enters the sound cavity 11, the float 131 can float on the water surface, so that the drain hole 13 is opened, and the water flows out of the drain hole 13. After the water flows out, the float 131 covers the drain hole 13 again. By setting the limiting rod 132 to limit the float 131, the float 131 can accurately cover the drain hole 13 along the direction of the limiting rod 132 extending into the drain hole 13. By controlling the controller to control the motor to drive the roller 3 connected to the motor to rotate, the belt 31 is driven between the two rollers 3, thereby driving the mounting block 1 to move between two adjacent electric poles. When the mounting block 1 moves from one electric pole to another electric pole, the controller controls the motor to reverse, so that the mounting block 1 moves in the opposite direction, thereby realizing reciprocating movement between two electric poles, so that the camera can monitor a larger range, and the mounting block 1 can drive away birds in a larger range. By setting the blade 4, when the rotating rod 2 rotates, the blade 4 rotates, so that the blade 4 prunes the branches of trees near the power line to prevent the trees from growing too high and breaking the power line. The blade 4 is rotatably connected to the rotating rod 2. Because there is friction between the blade 4 and the rotating rod 2, the rotating rod 2 drives the blade 4 to rotate when it rotates. When the tree branches are thicker and the resistance to the blade 4 is greater, the blade 4 is blocked and stops rotating and contacts the tree branches. When the mounting block 1 moves, the blade 4 cuts the tree branches. By setting the torsional spring 41, when the blade 4 is blocked by thicker tree branches, the torsional spring 41 supports the blade 4, so that the blade 4 has a force to resist the tree branches, and the blade 4 is in close contact with the tree branches.
