Description

Technical Field

[0001] This invention relates to the field of power transmission facility technology, and in particular to a snake-repelling device for power transmission steel pipe poles and its method of use. Background Technology

[0002] Currently, people are increasingly building equipment in the wild, such as power poles. However, various animals often pose a threat to the normal operation of power poles outdoors. 35kV and 10kV power lines are an important part of the power system, undertaking the important task of transmitting and distributing electrical energy. For rural power grids, due to the limitations of terrain conditions and cost, in order to maintain the balance of the poles and prevent them from tilting due to the tension of the conductors or the influence of wind, all poles equipped with electrical equipment that may lose balance due to the tension of the conductors or strong winds must be equipped with guy wires to ensure the balance of the poles. Guy wires generally consist of an upper handle, a middle handle, and a lower handle.

[0003] While guy wires stabilize utility poles, they provide a ladder for animals like snakes to climb. Due to power lines and infrastructure, bird nests become dangerous "time bombs." Every spring and summer, birds flock to utility poles to build their nests and lay eggs. However, this beautiful ecological scene hides a hidden danger: snakes especially love to climb utility poles to feed on bird eggs. When a snake climbs a pole, its body length becomes a conductor. If it touches the power lines, it can easily cause the power lines to trip, resulting in adverse effects and economic losses for businesses. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a snake-repelling device for power transmission steel pipe poles and its usage method, which prevents snakes from climbing onto power transmission towers.

[0005] The technical solution to achieve the purpose of this invention is as follows: a snake-repelling device for power transmission steel pipe poles and its usage method, comprising a steel pipe climbing frame and a sleeve. The steel pipe climbing frame is fixedly installed on an external power transmission tower. The sleeve is sleeved on the steel pipe climbing frame. A rotating sleeve is movably sleeved on the outer side wall of the sleeve. Multiple conical spikes are provided on the outer side wall of the rotating sleeve. A movable sleeve is provided below the sleeve and is movably sleeved on the steel pipe climbing frame. The steel pipe climbing frame is internally provided with a driving mechanism and a triggering mechanism. The driving mechanism includes a transmission gear ring, a drive motor, a rotating shaft, and a transmission gear. The triggering mechanism includes a mounting groove, a pressure plate, a pull rod, and a pressure trigger.

[0006] In some embodiments, the transmission gear ring is embedded in the upper inner wall of the rotating sleeve, the drive motor is embedded in the upper left side of the sleeve, the rotating shaft is fixedly mounted on the output end of the drive motor, the transmission gear is fixedly mounted on the rotating shaft, and the transmission gear meshes with the transmission gear ring.

[0007] In some embodiments, the mounting groove is located inside the lower part of the sleeve, the pressure plate is an annular plate adapted to the size of the mounting groove, the pressure plate is movably mounted inside the upper part of the mounting groove, there are two pull rods, the two pull rods are symmetrically fixedly mounted on the bottom wall of the pressure plate, the pressure trigger is fixedly mounted inside the lower part of the mounting groove, the bottom of the pull rod penetrates downward through the bottom wall of the sleeve and is fixedly connected to the movable sleeve, a spring is sleeved on both pull rods, and the pressure trigger is electrically connected to the drive motor.

[0008] In some embodiments, a fixing screw groove is provided on the upper side wall of the sleeve, the fixing screw groove penetrates the inner and outer side walls of the sleeve, and a fixing bolt is installed inside the fixing screw groove by means of threads.

[0009] In some embodiments, a positioning block is fixedly installed on one end of the fixing bolt near the steel pipe climbing frame, and the positioning block is made of rubber.

[0010] In some embodiments, a cylindrical groove is formed inside the lower part of the steel pipe climbing frame. A mounting bearing is embedded in the lower part of the cylindrical groove. A drive shaft is fixedly installed on the inner ring of the mounting bearing. A drive block is movably installed inside the steel pipe climbing frame. The drive shaft passes through the upper and lower walls of the drive block and is threadedly connected to the drive block. Two movable grooves are symmetrically formed on the outer wall of the steel pipe climbing frame corresponding to the position of the drive shaft. The movable grooves pass through the side wall of the steel pipe climbing frame and communicate with the interior of the steel pipe climbing frame. A connecting block is provided at the upper part of the interior of the movable groove. The side wall of the two connecting blocks that are close to each other is fixedly connected to the drive block, and the side wall of the two connecting blocks that are far apart is fixedly connected to the movable sleeve.

[0011] In some embodiments, a drive gear is fixedly installed on the top of the drive shaft, and a drive gear ring is fixedly installed on the lower inner wall of the rotating sleeve. The drive gear ring is located inside the sleeve, and a rotatable connecting gear is movably installed inside the sleeve corresponding to the position of the drive gear ring. The connecting gear meshes with the drive gear ring and the drive gear respectively. A connecting seat is fixedly installed on the top of the steel pipe climbing frame. Two extrusion plates are symmetrically arranged inside the connecting seat. An adjusting shaft is movably installed inside the lower part of the connecting seat. The adjusting shaft has two opposite threads. The adjusting shaft is threaded to the two extrusion plates through the two opposite threads. A knob is fixedly installed on one end of the adjusting shaft.

[0012] This invention also discloses a method for using a snake-repelling device for power transmission steel pipe poles, comprising the following steps:

[0013] Step 1: When the snake climbs up the steel pipe climbing frame, after the snake climbs onto the movable sleeve, since the movable sleeve is movably connected to the steel pipe climbing frame, the movable sleeve will move downward under the action of the snake's gravity, and the movable sleeve will then drive the pull rod to move downward.

[0014] Step 2: The pull rod and the pressure plate are fixedly connected. The pressure plate will move downward inside the mounting groove. The downward movement of the pressure plate will squeeze the pressure trigger, thus triggering the pressure trigger.

[0015] Step 3: The pressure trigger starts the drive motor inside the sleeve. The drive motor causes the shaft to rotate and the transmission gear to rotate. The transmission gear meshes with the transmission gear ring, which in turn drives the rotating sleeve to rotate on the sleeve. The rotation of the rotating sleeve will cause the snake on the rotating sleeve to be thrown off under the action of centrifugal force.

[0016] Step 4: When the snake climbs onto the movable sleeve, it will move downwards under the influence of gravity. The movable sleeve will then drive the transmission block to move downwards through the connecting block. The transmission block is threadedly connected to the transmission shaft. When the transmission block moves downwards, the transmission shaft will be driven to rotate. The drive gear will be driven to rotate by the transmission shaft, and the drive gear will drive the connecting gear to rotate. The connecting gear will then drive the drive gear ring to rotate, which in turn will drive the rotating sleeve to rotate. At the same time, a spring is sleeved on the transmission shaft. When the snake climbs onto the rotating sleeve and the movable sleeve, the rotating sleeve will be driven to rotate, throwing the snake away and preventing it from climbing the power transmission tower.

[0017] The significant advantages of this invention compared to existing technologies are:

[0018] Firstly, this invention incorporates a triggering mechanism and a driving mechanism. When the snake climbs upwards on the steel pipe climbing frame, it climbs onto the movable sleeve. Since the movable sleeve is movably fitted onto the steel pipe climbing frame, under the action of the snake's gravity, the movable sleeve will move downwards. The movable sleeve will then drive the pull rod to move downwards. The pull rod is fixedly connected to the pressure plate, so the pressure plate will move downwards inside the mounting groove. The downward movement of the pressure plate will squeeze the pressure trigger, causing the pressure trigger to be triggered. The pressure trigger will then start the drive motor inside the sleeve. The drive motor will cause the rotating shaft to drive the transmission gear to rotate. The transmission gear meshes with the transmission gear ring, thereby causing the rotating sleeve to rotate on the sleeve. The rotation of the rotating sleeve will cause the snake on the rotating sleeve to be thrown off under the action of centrifugal force, thus preventing the snake from climbing onto the power transmission tower.

[0019] Secondly, in this invention, the rotating fixing bolt moves inside the fixing bolt groove to squeeze the steel pipe climbing frame, thereby fixing the sleeve on the steel pipe climbing frame. At the same time, a positioning block is installed on the fixing bolt, which can increase the friction between the fixing bolt and the steel pipe climbing frame, making the fixation more stable.

[0020] Thirdly, in this invention, when the snake climbs onto the movable sleeve, the movable sleeve will move downwards under the action of gravity. The movable sleeve will then drive the transmission block to move downwards through the connecting block. The transmission block is threadedly connected to the transmission shaft. When the transmission block moves downwards, the transmission shaft will be driven to rotate. The drive gear will be driven to rotate by the transmission shaft, and the drive gear can drive the connecting gear to rotate. The connecting gear will then drive the drive gear ring to rotate, thereby driving the rotating sleeve to rotate. At the same time, a spring is sleeved on the transmission shaft. When the snake climbs onto the rotating sleeve and the movable sleeve, the rotating sleeve will be driven to rotate, throwing the snake away and preventing the snake from climbing the power transmission tower. Compared with the first embodiment, this embodiment does not require an external power source, saving resources.

[0021] This solved the problem of snakes climbing power transmission towers, which could easily cause dangerous situations. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] This invention provides an improved snake-repelling device for power transmission steel pipe poles and its method of use. The technical solution of this invention is as follows:

[0033] Example 1: As Figure 1 As shown, a snake-repelling device for power transmission steel pipe poles includes a steel pipe climbing frame 1 and a sleeve 2. The steel pipe climbing frame 1 is a cylindrical pole and is fixedly installed on an external power transmission tower. The sleeve 2 is a hollow cylindrical structure and is sleeved on the steel pipe climbing frame 1. A rotating sleeve 3 is movably sleeved on the outer wall of the sleeve 2. The rotating sleeve 3 is a hollow cylindrical structure and has multiple conical spikes 4 on its outer wall. A movable sleeve 5 is provided below the sleeve 2. The movable sleeve 5 is a hollow cylindrical structure and is movably sleeved on the steel pipe climbing frame 1. The steel pipe climbing frame 1 is equipped with a driving mechanism and a triggering mechanism.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment, the driving mechanism includes a transmission gear ring 6, a drive motor 7, a rotating shaft 8, and a transmission gear 9. The transmission gear ring 6 is a circular ring structure and is embedded in the upper inner wall of the rotating sleeve 3. The drive motor 7 is embedded in the upper left side of the inner side of the sleeve 2. The rotating shaft 8 is a cylindrical structure and is fixedly installed on the output end of the drive motor 7. The transmission gear 9 is a circular structure and is fixedly installed on the rotating shaft 8. The transmission gear 9 meshes with the transmission gear ring 6. When the drive motor 7 is started, the drive motor 7 causes the rotating shaft 8 to drive the transmission gear 9 to rotate. The transmission gear 9 meshes with the transmission gear ring 6, thereby driving the rotating sleeve 3 to rotate on the sleeve 2.

[0035] like Figure 3As shown, the triggering mechanism includes a mounting groove 10, a pressure plate 11, a pull rod 12, and a pressure trigger 13. The mounting groove 10 is an annular groove located inside the lower part of the sleeve 2. The pressure plate 11 is an annular plate that matches the size of the mounting groove 10 and is movably mounted inside the upper part of the mounting groove 10. The pull rod 12 is a cylindrical structure, and there are two pull rods 12. The two pull rods 12 are symmetrically fixedly mounted on the bottom wall of the pressure plate 11, and the bottom of the pull rod 12 penetrates downward through the bottom wall of the sleeve 2 and is fixedly connected to the movable sleeve 5. A spring is sleeved on each of the two pull rods 12. The pressure trigger 13 is fixedly mounted inside the lower part of the mounting groove 10 and is electrically connected to the drive motor 7. The triggering mechanism works as follows: When the snake climbs upward on the steel pipe climbing frame 1, it climbs onto the movable sleeve 5. Since the movable sleeve 5 is movably connected to the steel pipe climbing frame 1, it moves downward under the weight of the snake. The movable sleeve 5 then drives the pull rod 12 to move downward. The pull rod 12 is fixedly connected to the pressure plate 11, so the pressure plate 11 moves downward inside the mounting groove 10. The downward movement of the pressure plate 11 squeezes the pressure trigger 13, triggering it. The pressure trigger 13 then starts the drive motor 7 inside the sleeve 2. After the drive motor 7 is started, the rotating sleeve 3 rotates. The rotation of the rotating sleeve 3, under the action of centrifugal force, throws the snake off the rotating sleeve 3, thus preventing the snake from climbing onto the power transmission tower.

[0036] like Figure 4 As shown, a fixing screw groove 14 is provided on the upper side wall of the sleeve 2. The fixing screw groove 14 is a cylindrical groove with internal threads. The fixing screw groove 14 penetrates the inner and outer walls of the sleeve 2. A fixing bolt 15 is installed inside the fixing screw groove 14 by means of threads. A positioning block 16 is fixedly installed on the end of the fixing bolt 15 near the steel pipe climbing frame 1. The positioning block 16 is made of rubber. When the sleeve 2 is put on the steel pipe climbing frame 1, the fixing bolt 15 is rotated. The fixing bolt 15 moves inside the fixing screw groove 14 and squeezes the steel pipe climbing frame 1, thereby fixing the sleeve 2 on the steel pipe climbing frame 1. At the same time, the positioning block 16 installed on the fixing bolt 15 can increase the friction between the fixing bolt 15 and the steel pipe climbing frame 1, making the fixation more stable.

[0037] Example 2: Based on Example 1, as follows Figure 5As shown, a cylindrical groove is formed inside the lower part of the steel pipe climbing frame 1. A mounting bearing 17 is embedded in the lower part of the cylindrical groove. The mounting bearing 17 has a circular structure. A drive shaft 18 is fixedly mounted on the inner ring of the mounting bearing 17. The drive shaft 18 has a threaded cylindrical structure. A drive block 19 is movably installed inside the steel pipe climbing frame 1. The drive block 19 is a circular block. The drive shaft 18 passes through the upper and lower walls of the drive block 19 and is threadedly connected to the drive block 19. Two movable grooves 20 are symmetrically formed on the outer wall of the steel pipe climbing frame 1, corresponding to the position of the drive shaft 18. The movable grooves 20 have a rectangular structure and pass through the steel pipe climbing frame 1. The side wall of the pipe climbing frame 1 is connected to the interior of the steel pipe climbing frame 1. A connecting block 21 is provided above the interior of the movable groove 20. The connecting block 21 is a rectangular block. The side wall of the two connecting blocks 21 that are close to each other is fixedly connected to the transmission block 19. The side wall of the two connecting blocks 21 that are far apart is fixedly connected to the movable sleeve 5. Thus, when the snake climbs onto the movable sleeve 5, the movable sleeve 5 will move downward under the action of gravity. The movable sleeve 5 will then drive the transmission block 19 to move downward through the connecting block 21. The transmission block 19 is threadedly connected to the transmission shaft 18. When the transmission block 19 moves downward, the transmission shaft 18 will be driven to rotate.

[0038] A drive gear 22 is fixedly installed on the top of the drive shaft 18. The drive gear 22 has a circular structure. A drive gear ring 23 is fixedly installed on the lower inner wall of the rotating sleeve 3. The drive gear ring 23 has a circular structure and is located inside the sleeve 2. A rotatable connecting gear 24 is movably installed inside the sleeve 2 corresponding to the position of the drive gear ring 23. The connecting gear 24 meshes with the drive gear ring 23 and the drive gear 22 respectively, so that when the drive shaft 18 rotates, the drive gear 22 is driven to rotate by the drive shaft 18. The drive gear 22 can drive the connecting gear 24 to rotate, and the connecting gear 24 will drive the drive gear ring 23 to rotate, thereby driving the rotating sleeve 3 to rotate. At the same time, a spring is sleeved on the drive shaft 18. When the snake climbs onto the rotating sleeve 3 and the movable sleeve 5, the rotating sleeve 3 will be driven to rotate, throwing the snake away, so that the snake cannot climb the power transmission tower. Compared with the first embodiment, this embodiment does not require an external power source, saving resources.

[0039] Example 3: Based on Example 1, a connecting seat 25 is fixedly installed on the top of the steel pipe climbing frame 1. The connecting seat 25 is a hollow cylindrical structure. Two extrusion plates 26 are symmetrically arranged inside the connecting seat 25. The extrusion plates 26 are arc-shaped plates. An adjusting shaft 27 is movably installed in the lower part of the connecting seat 25. The adjusting shaft 27 is a cylindrical structure with two opposite threads. The adjusting shaft 27 is threaded to the two extrusion plates 26 through the two opposite threads. A knob 28 is fixedly installed at one end of the adjusting shaft 27. Through the setting of the connecting seat 25, the device can be connected to the external tower. The bottom of the external tower is inserted into the interior of the connecting seat 25. By rotating the adjusting shaft 27 by the knob 28, the adjusting shaft 27 will cause the two extrusion plates 26 to move towards the center inside the connecting seat 25, thereby extruding and fixing the bottom of the tower, thus achieving the effect of facilitating the connection of the device to the external tower.

[0040] This embodiment discloses a method for using a snake-repelling device for power transmission steel pipe poles, including the following steps:

[0041] Step 1: With the triggering mechanism and driving mechanism set up, when the snake climbs up on the steel pipe climbing frame 1, after the snake climbs onto the movable sleeve 5, since the movable sleeve 5 is movably connected to the steel pipe climbing frame 1, under the action of the snake's gravity, the movable sleeve 5 will move downward, and the movable sleeve 5 will then drive the pull rod 12 to move downward.

[0042] Step 2: The pull rod 12 is fixedly connected to the pressure plate 11, and the pressure plate 11 will move downward inside the mounting groove 10. The downward movement of the pressure plate 11 will squeeze the pressure trigger 13, thereby triggering the pressure trigger 13.

[0043] Step 3: The pressure trigger 13 starts the drive motor 7 inside the sleeve 2. The drive motor 7 causes the rotating shaft 8 to drive the transmission gear 9 to rotate. The transmission gear 9 meshes with the transmission gear ring 6, which drives the rotating sleeve 3 to rotate on the sleeve 2. The rotation of the rotating sleeve 3 will throw the snake on the rotating sleeve 3 away under the action of centrifugal force, thus preventing the snake from climbing onto the power transmission tower.

[0044] Step 4: When the snake climbs onto the movable sleeve 5, it will move downwards under the influence of gravity. The movable sleeve 5 will then drive the transmission block 19 to move downwards via the connecting block 21. The transmission block 19 is threadedly connected to the transmission shaft 18. When the transmission block 19 moves downwards, the transmission shaft 18 will be driven to rotate. The drive gear 22 will be driven to rotate by the transmission shaft 18. The drive gear 22 can drive the connecting gear 24 to rotate. The connecting gear 24 will drive the drive gear ring 23 to rotate, thereby driving the rotating sleeve 3 to rotate. At the same time, a spring is sleeved on the transmission shaft 18. When the snake climbs onto the rotating sleeve 3 and the movable sleeve 5, the rotating sleeve 3 will be driven to rotate, throwing the snake away and preventing it from climbing the power transmission tower. Compared with Embodiment 1, this embodiment does not require an external power source, saving resources.
