Description

Technical Field

[0001] This invention belongs to the field of bird deterrent technology, and specifically relates to a device for preventing birds from nesting on high-voltage power lines. Background Technology

[0002] High-voltage lines play a crucial role in power transmission. In cities, they are generally laid underground as cables, while in the countryside, they are overhead, supported by high-voltage towers. Because these towers are often located in sparsely populated areas, they provide easy access for birds. Birds nest on these towers, and their activities there, along with the transport of nesting materials like branches, weeds, and even electrical wires, can damage the transmission lines and the towers themselves. Most current bird deterrent devices are electronic, using sound or reflective devices. However, some require replacement of their power sources after a period of operation, necessitating timely replacement by patrol personnel. Furthermore, most devices are fixed to the high-voltage lines, and over time, birds adapt to these devices, rendering them ineffective at deterring birds. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a high-voltage line bird nesting prevention device. This device, through the cooperation of the mounting frame and the folding component, can drive the bird-repelling mechanism to slide, ensuring that the bird-repelling mechanism is in a different position each time, preventing birds from adapting to the bird-repelling mechanism and affecting the bird-repelling effect. The folding component facilitates the folding of the device, improving its portability. The mounting frame is provided to support the device and ensure its normal operation.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A high-voltage power line bird nesting prevention device includes a mounting frame, a folding component, and a bird deterrent mechanism. The folding component is mounted on the mounting frame. The bird deterrent mechanism includes spikes, a mounting plate, a mounting shaft, a gear, and a rack. The mounting plate is mounted on the folding component. Several spikes are evenly distributed on the mounting shaft. Several mounting shafts are evenly mounted on the mounting plate. The gear is fixedly mounted on the mounting shaft. The rack is mounted on the folding component, with the rack located below the gear, and the gear meshes with the rack.

[0006] Preferably, the bird deterrent mechanism further includes an adjusting bolt and a side plate. The side plate is fixedly installed on one end of the rack, and the adjusting bolt is installed on the folding part. The side plate and the adjusting bolt are threaded together. The setting of the adjusting bolt and the side plate facilitates the movement of the rack. The movement of the rack drives the gear to rotate. The rotation of the gear drives the mounting shaft to rotate. The rotation of the mounting shaft drives the needle to rotate, thereby achieving the purpose of adjusting the tilt angle of the needle.

[0007] Preferably, the mounting frame includes a first fixed column, a second fixed column, a first rotating arm, a second rotating arm, and a connector. Two first rotating arms and two second rotating arms are provided. The two first rotating arms are symmetrically fixed to both ends of the first fixed column, and the two second rotating arms are symmetrically fixed to both ends of the second fixed column. The first rotating arms at both ends of the first fixed column are connected to the second rotating arms at both ends of the second fixed column via connectors. Mounting blocks are fixedly installed on the outer sides of the first and second rotating arms, and U-shaped clamps are also installed on the mounting blocks to facilitate fixing the device to the cable. The mounting frame supports the device, ensuring its normal bird-repelling operation and greatly improving the bird-repelling quality. The connectors connect the first and second rotating arms, ensuring their safety and stability during operation.

[0008] Preferably, the connecting component includes connecting plates, limiting bolts, and nuts disposed on both sides of the end of the second rotating arm. The connecting plates are fixedly connected to the second rotating arm. Through holes are opened on the first rotating arm and on the connecting plates disposed on both sides of the end of the second rotating arm. The limiting bolts are disposed in the through holes. The limiting bolts are fixed on the first and second rotating arms by the nuts. The cooperation of the limiting bolts and nuts can fix the first and second rotating arms, preventing the first and second rotating arms from folding during operation, thus greatly ensuring the normal operation of the device.

[0009] Preferably, the folding component includes a folding plate, a sliding sleeve, a guide rod, a spring, and a support frame. The folding plate and the sliding sleeve are symmetrically arranged on both sides of the center line of the support frame. A fixed seat is fixedly installed at the bottom upper end of the folding plate, and the fixed seat is rotatably installed on the support frame. A support block is fixedly installed on the sliding sleeve. The sliding sleeves arranged on both sides of the support frame are slidably connected to the first fixed column and the second fixed column, respectively. The guide rod is slidably installed on the support block, and the upper end of the guide rod is fixedly installed on the support frame. The spring is sleeved on the guide rod, and the spring is located between the fixed block and the support block. A limiting component is also fixedly installed on the support block. The limiting component cooperates with the folding plate. The folding component facilitates the folding of the device, makes it easy for workers to carry, and improves the installation efficiency and installation quality of the device.

[0010] Preferably, the folding plate has a groove, and the rack is slidably disposed in the groove. The groove facilitates the installation of the rack and ensures the normal operation of the rack.

[0011] Preferably, the support frame includes a support plate, a fixing block, a rotating sleeve, and a fixing shaft. Mounting grooves are formed at both ends of the centerline of the support plate. The fixing shaft is fixedly mounted on the two side walls of the mounting grooves. The rotating sleeve is rotatably mounted on the fixing shaft. The fixing block is fixedly mounted on the rotating sleeve. The fixing seat at the bottom of the folding plate is rotatably mounted on the fixing shaft. The upper end of the guide rod is fixedly mounted on the fixing block. The support plate supports the folding plate, ensuring its normal operation. The rotating sleeve allows the folding plate to rotate around the fixing shaft, ensuring normal folding of the device and improving its portability.

[0012] Preferably, the limiting component includes a handle, a threaded rod, a movable plate, and a limiting rod. The limiting rods are symmetrically arranged on both sides of the top of the movable plate and are fixedly connected to the movable plate. The threaded rod is rotatably mounted on the support block. The movable plate is threadedly connected to the threaded rod. The handle is fixedly mounted on the threaded rod. The handle facilitates the rotation of the threaded rod, which in turn moves the movable plate. The movement of the movable plate moves the limiting rod, which in turn restricts the folding plate, thereby ensuring the safety and stability of the folding plate during operation.

[0013] Preferably, the device also includes a bird deterrent component, which includes a mounting base, a crank, a support rod, and a reflective wind cup installed at the end of the support rod. The mounting base is fixedly installed at the bottom of the support plate, and the crank is rotatably mounted on the mounting base. Several support rods are provided, and the support rods are distributed circumferentially at both ends of the crank. The reflective wind cup can drive the crank to rotate under the action of wind force. The reflective wind cup can reflect sunlight to avoid large birds from approaching, thereby improving the efficiency and quality of bird deterrence.

[0014] Preferably, the bird deterrent device further includes a sleeve, a pole, and a collision ball. The sleeve is rotatably mounted on the connecting rod neck of the crank, and several sleeves are evenly distributed on each connecting rod neck of the crank. The pole is fixedly mounted on the bottom of the sleeve, and the collision ball is fixedly mounted on the bottom of the pole. The rotation of the crank will cause the sleeve to rotate up and down, and the up and down movement of the sleeve will cause the pole to move up and down. The up and down movement of the pole will cause the collision ball to strike, and the collision ball will make a sound, thereby achieving the purpose of deterring birds.

The U-shaped clamps 107 facilitate fixing the device to the cable 5, ensuring that the device remains stable during operation.

[0050] To ensure the range of motion of the bird deterrent mechanism 3, the lengths of the first fixed post 102 and the second fixed post 105 can be adjusted as needed to achieve the purpose of repelling birds.

[0051] Mounting bracket 1 is used to support the device, ensuring that the device can work normally to drive away birds, which greatly improves the quality of bird driving. Connector 106 is used to connect the first rotating arm 103 and the second rotating arm 104, ensuring the safety and stability of the first rotating arm 103 and the second rotating arm 104 during operation.

[0052] As an optimization of this embodiment, in order to facilitate the folding of the first rotating arm 103 and the second rotating arm 104 and to ensure that the first rotating arm 103 and the second rotating arm 104 remain fixed during operation, such as Figure 3As shown, the connector 106 includes a connecting plate 108, a limiting bolt 109, and a nut 1010 disposed on both sides of the end of the second rotating arm 104. The connecting plate 108 is fixedly connected to the second rotating arm 104. Through holes are opened on the first rotating arm 103 and on the connecting plate 108 disposed on both sides of the end of the second rotating arm 104. The limiting bolt 109 is disposed in the through hole and is fixed on the first rotating arm 103 and the second rotating arm 104 by the nut 1010.

[0053] The combination of the limiting bolt 109 and the nut 1010 can fix the first rotating arm 103 and the second rotating arm 104, preventing the first rotating arm 103 and the second rotating arm 104 from folding during operation, thus greatly ensuring the normal operation of the device.

The handle 2011 is fixedly mounted on the threaded rod 2014.

[0061] The handle 2011 is designed to facilitate the rotation of the threaded rod 2014. The rotation of the threaded rod 2014 enables the moving plate 2013 to move. The movement of the moving plate 2013 causes the limiting rod 2012 to move. The movement of the limiting rod 2012 enables the restriction of the folding plate 201, thereby ensuring the safety and stability of the folding plate 201 during operation.
