Description

Technical Field

[0001] This invention relates to the field of power grid protection technology, specifically to an electric shock bird deterrent device for power transmission lines. Background Technology

[0002] With the gradual improvement of my country's ecological environment and the increasing awareness of bird protection, the types and numbers of birds are gradually increasing. However, a related problem is the growing prevalence of birds building nests and roosts directly above the straight insulator strings or jumper insulator strings of power transmission line towers (poles), leading to frequent power line faults. Birds may perch, nest, or rest on power lines, which can cause several problems:

[0003] 1. Risk of electric shock: When birds come into contact with live power lines, they may be electrocuted, which can not only harm the birds themselves, but also cause power system failures or even fires.

[0004] 2. Short circuits and faults: When birds perch or nest on power lines, they may cause short circuits between conductors, leading to power system failures and power outages.

[0005] 3. Maintenance difficulties: The presence of birds may increase the difficulty of maintaining transmission lines. Bird droppings and nesting materials may clog insulators and equipment, affecting the normal operation of the lines.

[0006] Traditional bird deterrent devices typically use electric nets to scare away birds, powered by solar panels. This method is highly effective. However, due to the large number of utility poles requiring protection, the cost of installing solar panels over a large area is too high. Therefore, this method of bird deterrence has not been widely adopted. Instead, bird spikes, wind-powered reflective bird deterrents, composite insulators with additional umbrellas, ultrasonic bird deterrents, and bird barriers have been used. However, these methods are not very effective at deterring or preventing bird damage, as birds can quickly adapt and render these measures ineffective. Therefore, a new type of bird deterrent device is urgently needed to protect the normal operation of the power grid. Summary of the Invention

[0007] Therefore, it is necessary to provide an electric shock bird deterrent device for power transmission lines to address the problems of existing technologies.

[0008] To address the problems of existing technologies, the present invention adopts the following technical solution: an electric shock bird deterrent device for power transmission lines, comprising a crossbeam fixedly mounted on a utility pole, and further comprising a power generation component, a power disconnector, and an electric shock component mounted on the crossbeam. The power generation component includes a generator fixedly mounted on the crossbeam, and a wind turbine and a chuck coaxially connected to the generator's input shaft. The power disconnector includes a high-level tube and a low-level tube with openings at their top ends, the high-level tube and the low-level tube being connected at their bottom ends to form a U-shaped connector. A device for floating upwards and locking the chuck is movably mounted inside the high-level tube. The float of the disc has several limiting holes formed on the chuck for the insertion of the float. The top of the low-position tube is used to receive rainwater and is lower than the top of the high-position tube. The electric shock assembly includes several electric grid mechanisms fixed on the crossbeam. Each electric grid mechanism includes several discharge rods arranged in sequence at equal intervals and electrically connected to the output end of the generator, a cleaning rod for reciprocating to clean several discharge rods along the length of the discharge rods, and a drive rod for driving the reciprocating motion of the cleaning rods. An intermittent transmission mechanism is connected between the drive rod and the input shaft of the generator.

[0009] Furthermore, the power generation also includes a mounting plate fixedly mounted on the crossbeam, a limiting cylinder fixedly mounted on the mounting plate, a drive shaft rotatably mounted inside the limiting cylinder, a support base fixedly mounted on the limiting cylinder, a protective cover fixedly mounted on the support base, and a dust cover fixedly mounted on the protective cover. The dust cover is umbrella-shaped and has a vent at the connection point with the protective cover. The wind turbine is coaxially and fixedly connected to the drive shaft. The connection point between the drive shaft and the dust cover is rotatably connected via a bearing. The chuck is coaxially and fixedly mounted on the drive shaft. The high-level tube is fixedly connected to the outer wall of the limiting cylinder, and the upper opening of the high-level tube passes through the support base.

[0010] Furthermore, several limiting strips are formed in a ring along the axis of the inner wall of the high-position tube.

[0011] Furthermore, a guide frame is fixedly provided at the end of the high-position tube. The guide frame is used to guide the float to move upward so that the float can be accurately inserted into the limiting hole.

[0012] Furthermore, a connecting ring frame is fixedly installed at the bottom of the high-position tube.

[0013] Furthermore, a liquid collecting funnel is provided at the top opening of the lower tube, and the top opening of the liquid collecting funnel is lower than the top opening of the higher tube.

[0014] Furthermore, the intermittent transmission mechanism includes an extension shaft coaxially fixed to the generator input shaft, a drive disk coaxially fixed to the extension shaft, a transmission rod rotatably mounted on a crossbeam, and a transfer disk coaxially fixed to the transmission rod. A toggle lever is formed on the drive disk, and several transfer levers are formed in a ring along the axis of the side wall of the transfer disk. The toggle lever meshes with the transfer levers.

[0015] Furthermore, the electric shock assembly also includes a limiting slide rod fixedly disposed on one side of each electric grid mechanism and a reciprocating lead screw rotatably disposed on the crossbeam via a bearing seat. The reciprocating lead screw is connected to the drive rod via a bevel gear set. The drive rod on each electric grid mechanism is connected to the synchronous pulley via a synchronous pulley. The drive rod is connected to one of the drive rods via a bevel gear set and a synchronous pulley via a synchronous pulley. One end of the cleaning rod is slidably engaged with the limiting slide rod, and the other end is threadedly connected to the reciprocating lead screw.

[0016] The beneficial effects of this invention compared to the prior art are:

[0017] Firstly, this invention utilizes the principle of communicating vessels to cause the liquid level to rise during rainy weather, which in turn causes the float to rise and the limiting chuck to rotate, thereby cutting off the power to the device, ensuring that it stops operating during rainy weather and extending the device's service life.

[0018] Secondly, this device uses a wind turbine to generate electricity, which can be used immediately upon generation, saving energy and protecting the environment, thus reducing the cost of bird control.

[0019] Thirdly, this device has a simple mechanical structure, low production cost, and obvious bird-repelling effect, making it suitable for widespread use. Attached Figure Description

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] refer to Figures 1 to 9 :

[0032] An electric shock bird deterrent device for power transmission lines includes a crossbeam 1 fixedly mounted on a utility pole, and a power generation component, a power disconnector 13, and an electric shock component mounted on the crossbeam 1. The power generation component includes a generator 4 fixedly mounted on the crossbeam 1, a wind turbine 6 coaxially connected to the input shaft of the generator 4, and a chuck 11. The power disconnector 13 includes a high-level tube 14 and a low-level tube 19 with openings at their top ends. The high-level tube 14 and the low-level tube 19 are connected at their bottom ends to form a U-shaped connector. A float 16 is movably mounted inside the high-level tube 14 to float upwards and lock the chuck 11. The chuck 11 has a... Several limiting holes 12 for inserting floats 16 are provided. The top end of the low-position tube 19 is used to receive rainwater and is lower than the top end of the high-position tube 14. The electric shock assembly includes several electric grid mechanisms 26 fixedly set on the crossbeam 1. Each electric grid mechanism 26 includes several discharge rods 27 arranged in sequence at equal intervals and electrically connected to the output end of the generator 4, a cleaning rod 31 for reciprocating cleaning of several discharge rods 27 along the length direction of the discharge rods 27, and a drive rod 28 for driving the cleaning rods 31 to reciprocate. An intermittent transmission mechanism is connected between the drive rod 28 and the input shaft of the generator 4.

[0033] When the device is running, the wind turbine 6 is driven to rotate by the wind. The rotation of the wind turbine 6 drives the input shaft of the generator 4 to rotate, which in turn makes the generator 4 run. The generator 4 converts kinetic energy into electrical energy, which is then transmitted to the discharge rod 27. When a bird tries to land on the crossbeam 1 to rest or build a nest, the discharge rod 27 will discharge electricity to the bird (it should be noted that the electric shock force of the discharge will only scare the bird away, but will not harm it). This will stimulate the bird to run away. When the generator 4 is running, the input shaft of the generator 4 also drives the intermittent transmission mechanism to run. The intermittent transmission mechanism drives the drive rod 28 to rotate intermittently. The intermittent rotation of the drive rod 28 drives the cleaning rod 31 to move slowly back and forth along the discharge rod 27, cleaning the debris on the discharge rod 27 and ensuring that the discharge rod 27 discharges normally.

[0034] On rainy days, birds are less active, and if the discharge rod 27 continues to discharge, rainwater can easily cause short circuits and damage to the device. At this time, rainwater will gradually accumulate in the low-level tube 19. As the rainwater accumulates in the low-level tube 19, the liquid level in the high-level tube 14 will rise to the same height as the liquid level in the low-level tube 19 due to the principle of communicating vessels. The top of the low-level tube 19 is lower than the top of the high-level tube 14. The rainwater will at most fill the low-level tube 19, but it will not flow out from the top of the high-level tube 14, thus ensuring that the rainwater will not flow out from the top of the high-level tube 14 and affect the normal operation of the device. During this process, the float 16 in the high-level tube 14 will rise until it is inserted into a limiting hole 12 on the chuck 11, thereby limiting the chuck 11 and causing the wind turbine 6 to stop rotating. As the wind turbine 6 stops rotating, the generator 4 also stops working. At this time, the discharge rod 27 is in a de-energized state, thereby temporarily stopping the operation of the entire device to achieve the purpose of protecting the device and relatively reducing the wear and tear of various parts, increasing the service life of the device. When the rain stops, the rainwater in the low-level tube 19 and the high-level tube 14 is evaporated by the sun. At this time, the float 16 is disengaged from the limiting hole 12 under the action of gravity. At this time, the chuck 11 loses its limiting position, and the wind turbine 6 continues to rotate normally, driving the device to perform bird-repelling work normally.

[0035] To showcase the detailed structure of the power generation components, the following features are specifically included:

[0036] The power generation system also includes a mounting plate 2 fixedly mounted on the crossbeam 1, a limiting cylinder 3 fixedly mounted on the mounting plate 2, a drive shaft 7 rotatably mounted inside the limiting cylinder 3, a support base 8 fixedly mounted on the limiting cylinder 3, a protective cover 9 fixedly mounted on the support base 8, and a dust cover 10 fixedly mounted on the protective cover 9. The dust cover 10 is umbrella-shaped and has a vent at its connection with the protective cover 9. The wind turbine 6 is coaxially and fixedly connected to the drive shaft 7. The connection between the drive shaft 7 and the dust cover 10 is rotatably connected by a bearing. The chuck 11 is coaxially and fixedly mounted on the drive shaft 7. The high-level tube 14 is fixedly connected to the outer wall of the limiting cylinder 3, and the upper opening of the high-level tube 14 passes through the support base 8.

[0037] When the impeller 6 rotates, the impeller 6 drives the drive shaft 7 to rotate, and the drive shaft 7 drives the chuck 11 to rotate. When rainwater enters the low-level pipe 19 during rainy weather, the dust cover 10 prevents rainwater from entering the connection between the drive shaft 7 and the limiting cylinder 3. In addition, the vent between the dust cover 10 and the protective cover 9 ensures that the top of the high-level pipe 14 is always in communication with the atmosphere, thus ensuring the normal operation of the U-shaped connector formed by the high-level pipe 14 and the low-level pipe 19.

[0038] To ensure that the float 16 can rise smoothly when the liquid level in the high-level pipe 14 rises, the following features are specifically designed:

[0039] Several limiting strips 15 are formed in a ring along the axis of the inner wall of the high-position tube 14.

[0040] The limiting strip 15 inside the high-level tube 14 ensures that the float 16 does not press against the inner wall of the high-level tube 14 under normal conditions, so that there is a gap between the inner wall of the high-level tube 14 and the outer wall of the float 16. This ensures that when water enters the low-level tube 19, the liquid level in the high-level tube 14 and the liquid level in the low-level tube 19 can rise simultaneously, thereby causing the float 16 to float with the liquid level.

[0041] To ensure that the float 16 can be accurately inserted into the limiting hole 12 after it rises, the following features are specifically provided;

[0042] A guide frame 17 is fixedly provided at the end of the high-position tube 14. The guide frame 17 is used to guide the float 16 to move upward so that the float 16 can be accurately inserted into the limiting hole 12.

[0043] During the upward movement of the float 16, guided by the guide frame 17, the float 16 can move vertically upward along the central axis of the high-position tube 14, thereby ensuring that the float 16 can be accurately inserted into the limiting hole 12.

[0044] To ensure that when there is no water in the high-level pipe 14 and the low-level pipe 19, the float 16 can stay at the bottom of the high-level pipe 14 without blocking it, the float is specifically designed with the following features:

[0045] A connecting ring frame 18 is fixedly installed at the bottom of the high-position tube 14.

[0046] Under normal circumstances, the float 16 will naturally fall to the connecting ring frame 18 due to gravity. The connecting ring frame 18 plays the role of supporting the float 16 and preventing the float 16 from getting stuck. In addition, the connecting ring frame 18 is a mesh structure, which does not affect the normal use of the communicating vessel.

[0047] To ensure that rainwater can be collected into the low-level pipe 19 as quickly as possible during rainfall, the following features are specifically designed:

[0048] A liquid collecting funnel 20 is provided at the top opening of the low-level tube 19, and the top opening of the liquid collecting funnel 20 is lower than the top opening of the high-level tube 14.

[0049] When it rains, the collection funnel 20 can receive more rainwater, which allows the float 16 to rise in time and stop the rotation of the chuck 11.

[0050] To demonstrate the detailed structure of the intermittent transmission mechanism, the following features are specifically included:

[0051] The intermittent transmission mechanism includes an extension shaft 5 coaxially fixed to the input shaft of the generator 4, a drive disk 21 coaxially fixed on the extension shaft 5, a transmission rod 23 rotatably mounted on the crossbeam 1, and a transfer disk 24 coaxially fixed on the transmission rod 23. A toggle rod 22 is formed on the drive disk 21, and several transfer rods 25 are formed in a ring along the axis of the side wall of the transfer disk 24. The toggle rod 22 meshes with the transfer rods 25.

[0052] When the device is running, the input shaft of the generator 4 drives the extension shaft 5 to rotate, the extension shaft 5 drives the drive disk 21 to rotate, the drive disk 21 rotates and drives the toggle lever 22 to rotate, the toggle lever 22 rotates and touches the adapter lever 25, causing the adapter disk 24 to rotate intermittently, and the rotation of the adapter disk 24 drives the transmission rod 23 to rotate.

[0053] To demonstrate the connection between the drive lever 28 and the sweeping lever 31, the following features are specifically provided:

[0054] The electric shock assembly also includes a limiting slide bar 30 fixedly disposed on one side of each electric grid mechanism 26 and a reciprocating lead screw 29 rotatably disposed on the crossbeam 1 via a bearing seat. The reciprocating lead screw 29 is connected to the drive rod 28 via a bevel gear set. The drive rod 28 on each electric grid mechanism 26 is connected via a synchronous pulley. The transmission rod 23 is connected to one of the drive rods 28 via a bevel gear set and a synchronous pulley. One end of the cleaning rod 31 is slidably engaged with the limiting slide bar 30, and the other end is threadedly connected to the reciprocating lead screw 29.

[0055] When the device is running, the rotation of the transmission rod 23 drives the rotation of the drive rod 28, and the rotation of the drive rod 28 drives the reciprocating screw 29 to rotate intermittently, so that the cleaning rod 31 slowly moves back and forth along the length of the discharge rod 27 to clean up debris under the intermittent rotation of the reciprocating screw 29.

[0056] Working principle: When the device is running, the wind turbine 6 is rotated by the wind, which drives the drive shaft 7 to rotate. The drive shaft 7 drives the chuck 11 to rotate and also drives the input shaft of the generator 4 to rotate, thus making the generator 4 run. The generator 4 converts kinetic energy into electrical energy, which is then transmitted to the discharge rod 27. When a bird tries to land on the crossbeam 1 to perch or build a nest, the discharge rod 27 will discharge electricity to the bird (it should be noted that the electric shock force will only scare the bird away, but will not harm it), causing the bird to be stimulated and escape. When the generator 4 is running, the generator 4... The input shaft drives the extension shaft 5 to rotate, the extension shaft 5 drives the drive disk 21 to rotate, the drive disk 21 rotates and drives the toggle rod 22 to rotate, the toggle rod 22 rotates and touches the adapter rod 25, causing the adapter disk 24 to rotate intermittently, the adapter disk 24 rotates and drives the transmission rod 23 to rotate, the transmission rod 23 rotates and drives the drive rod 28 to rotate, the drive rod 28 rotates and drives the reciprocating screw 29 to rotate intermittently, so that the cleaning rod 31 slowly moves back and forth along the length of the discharge rod 27 to clean up debris under the intermittent rotation of the reciprocating screw 29, ensuring that the discharge rod 27 discharges normally.

[0057] On rainy days, birds are less active, and if the discharge rod 27 continues to discharge, rainwater can easily cause short circuits and damage to the device. At this time, rainwater will gradually accumulate in the low-level tube 19. As the rainwater accumulates in the low-level tube 19, the liquid level in the high-level tube 14 will rise to the same height as the liquid level in the low-level tube 19 due to the principle of communicating vessels. The top of the low-level tube 19 is lower than the top of the high-level tube 14. The rainwater will at most fill the low-level tube 19, but it will not flow out from the top of the high-level tube 14, thus ensuring that the rainwater will not flow out from the top of the high-level tube 14 and affect the normal operation of the device. During this process, the float 16 in the high-level tube 14 will rise until it is inserted into a limiting hole 12 on the chuck 11, thereby limiting the chuck 11 and causing the wind turbine 6 to stop rotating. As the wind turbine 6 stops rotating, the generator 4 also stops working. At this time, the discharge rod 27 is in a de-energized state, thereby temporarily stopping the operation of the entire device to achieve the purpose of protecting the device and relatively reducing the wear and tear of various parts, increasing the service life of the device. When the rain stops, the rainwater in the low-level tube 19 and the high-level tube 14 is evaporated by the sun. At this time, the float 16 is dislodged from the limiting hole 12 under the action of gravity. At this time, the chuck 11 loses its limiting position, and the wind turbine 6 continues to rotate normally, driving the device to perform bird-repelling work normally.

[0058] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
