Description

Technical Field

[0001] This invention relates to the field of power line inspection technology, and more specifically to an auxiliary hoisting device for a power line inspection aircraft. Background Technology

[0002] To ensure an effective power supply, protecting power grid infrastructure has become an essential issue. Overhead transmission lines, as channels for transmitting electricity in the power grid, are crucial for ensuring smooth and stable power supply. The operational status of overhead lines directly affects the safety and stability of the power grid. Therefore, the inspection of overhead transmission lines is one of the important tasks of power grid operation and maintenance departments. Power inspection is an important method for the power industry to ensure the normal operation of the power supply system. Currently, there is a trend towards automated inspection using unmanned aerial vehicles (UAVs). However, existing UAV inspections involve directly mounting the cameras used for power inspection on the UAV's support frame. This method makes the cameras highly susceptible to dust and rain contamination during recording, affecting the accuracy of the inspection data. Furthermore, the UAV carrying the cameras is easily affected by air resistance, causing camera shaking, which also affects the accuracy of the inspection data and reduces the efficiency of power inspection. Therefore, we propose an auxiliary hanging device for power inspection UAVs. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides an auxiliary hoisting device for a power line inspection aircraft, including a suspension platform. Several hook seats are provided at the corners of the suspension platform, and the hook seats are fixedly connected to the top of the suspension platform. A platform body is fixedly connected to the side of the suspension platform away from the hook seats. The auxiliary hoisting device for the power line inspection aircraft also includes a hoisting mechanism composed of hoisting arms. The hoisting arms are symmetrically arranged on both sides of the platform body. The sides of two hoisting arms that are close to each other are fixedly connected to the surface of the platform body. Fixed rods are symmetrically arranged on both sides of the hoisting arms. The sides of two fixed rods that are close to each other are fixedly connected to the surface of the hoisting arms, and the ends of the fixed rods away from the hoisting arms are fixedly connected to the surface of the platform body. A fixed seat is fixedly connected to the end of the hoisting arm away from the platform body. The inner surface of the fixed seat... A connecting plate is fixedly connected to the wall. A first stabilizing plate and a second stabilizing plate are fixedly connected to both sides of the connecting plate, respectively. A placement mechanism is provided on the side of the connecting plate away from the fixed base. The placement mechanism includes a housing. The outer surface of the housing is fixedly connected to the ends of the first and second stabilizing plates away from the connecting plate. The housing is cone-shaped. The suspension platform is suspended at the bottom of the power inspection drone by a hook seat. The camera used for power inspection is placed inside the housing. The housing is cone-shaped and has a streamlined outer surface, which can reduce air resistance when the drone carries the housing, thereby avoiding affecting the flight efficiency of the drone. Fixed rods are symmetrically arranged on both sides of the suspension arm, thereby improving the connection strength between the suspension arm and the platform, preventing the suspension arm from bending under the influence of air resistance, and thus preventing the housing from shaking and affecting the inspection effect.

[0004] Furthermore, a compensation component is provided at the interval between the two hanging arms. The compensation component includes a frame, which is fixedly connected to the side of the platform away from the suspension platform. A first ring is fixedly connected to the side of the frame away from the platform. A spring is fixedly connected to the inner wall of the first ring, and the diameter of the spring gradually decreases from both ends to the middle. A second ring is fixedly connected to the end of the spring away from the first ring, and several springs are arranged along the circumference of the second ring. The inner wall of the second ring is fixedly connected to the outer surface of the shell. During long-term use, the shell may be damaged by rain corrosion or collision. The damaged shell will vibrate due to airflow during flight, and the vibration will affect the imaging effect of the camera inside the shell. By setting the spring, when the shell vibrates, it drives the second ring to vibrate. The vibration is transmitted to the spring, and the spring deforms, thereby buffering the shell and reducing the vibration of the shell. At the same time, the spring is designed to be thick at both ends and thin in the middle, which ensures the overall elasticity of the spring while making the middle part of the spring easier to deform, thereby improving the sensitivity of the spring buffer and further improving the inspection effect of the camera inside the shell.

[0005] Furthermore, a first reinforcing rod is horizontally arranged on the inner wall of the frame, and both ends of the first reinforcing rod are fixedly connected to the inner wall of the frame. Several second reinforcing rods are also arranged inside the frame, and the second reinforcing rods are arranged perpendicular to the first reinforcing rods. All of the second reinforcing rods are fixedly connected to the inner wall of the frame. By setting the second reinforcing rods and the first reinforcing rods, the strength of the frame is improved, and the spring deformation is prevented due to vibration caused by air resistance, thereby ensuring the buffering effect of the spring.

[0006] Furthermore, a limiting component is provided at the interval between the first ring body and the second ring body. The limiting component is provided at the interval between several springs, and several limiting components are provided along the circumference of the second ring body.

[0007] Furthermore, the limiting component includes a locking plate, and two locking plates are symmetrically arranged. The two locking plates are fixedly connected to the inner wall of the first ring body, and a sliding plate is slidably connected at the interval between the two locking plates. By setting the locking plates and the sliding plate, the first ring body and the second ring body will not rotate, thereby limiting the torsion of the outer shell through the second ring body, thereby further preventing the camera inside the outer shell from shaking and improving the inspection effect.

[0008] Furthermore, symmetrical fixing strips are provided at the interval between the first ring body and the slide plate, and the two fixing strips are respectively fixedly connected to the inner wall of the first ring body and the end of the slide plate at their respective ends. A buffer plate is provided at the interval between the two fixing strips, and the two ends of the buffer plate are respectively fixedly connected to the two fixing strips at their respective ends. Several buffer plates are provided. The outer surface of the buffer plate is provided with an elliptical groove. By providing the elliptical groove, the two sides of the buffer plate are made thinner, making the buffer plate easier to deform. When the outer shell shakes, it causes the second ring body to shake, which in turn causes the slide plate to slide inside the clamping plate, thereby squeezing the buffer plate. Under the elastic force of the buffer plate, the distance between the first ring body and the second ring body is limited, thereby avoiding excessive deformation of the spring and causing damage, thus improving the service life of the device.

[0009] Furthermore, the housing contains a placement platform, the outer surface of which is fixedly connected to the inner wall of the housing. A limiting groove is formed on the surface of the placement platform, and a slider is slidably connected to the inner wall of the limiting groove. A placement plate is fixedly connected to the side of the slider away from the placement platform, and the placement plate is slidably connected to the surface of the placement platform. A first telescopic rod is fixedly connected to the inner wall of the limiting groove, and the end of the first telescopic rod away from the limiting groove is fixedly connected to the surface of the slider. When placing the camera, the first telescopic rod is activated, extending and moving the slider. The slider's movement moves the placement plate, causing it to leave the housing, facilitating the placement of the camera. The first telescopic rod then retracts, allowing the placement plate to enter the housing, thus shielding the camera from dust and rainwater from the outside.

[0010] Furthermore, the placement plate is symmetrically provided with second telescopic rods inside. The ends of the two second telescopic rods that are far apart from each other are fixedly connected to the inner side of the placement plate. The ends of the two telescopic rods that are close to each other are fixedly connected to curved plates. The two ends of the curved plates are fixedly connected to fixed plates. Clamping plates are provided at the interval between the two curved plates, and the two ends of the clamping plates are rotatably connected to the two fixed plates respectively. When fixing the camera, the second telescopic rods are activated, the second telescopic rods extend, drive the curved plates to move, and further drive the two clamping plates closer to the base of the camera, thereby fixing the base of the camera.

[0011] Furthermore, the clamping plate has anti-slip grooves on the side away from the curved plate. There are several anti-slip grooves, and the anti-slip grooves are serpentine. When the clamping plate contacts the camera base, the anti-slip grooves increase the friction between the camera base and the clamping plate, thereby improving the fixing effect. At the same time, the serpentine shape of the anti-slip grooves increases the contact area between the anti-slip grooves and the camera base, thereby assisting the clamping plate in improving the fixing effect on the camera base and further preventing the camera from shaking and affecting the inspection effect.

[0012] Furthermore, a sliding rod is fixedly connected to the side of the curved plate away from the clamping plate. Two sliding rods are symmetrically arranged, and the outer surface of the sliding rod is slidably connected to the inner wall of the placement plate. Spring plates are symmetrically arranged at the interval between the clamping plate and the curved plate, and the two ends of the spring plates are fixedly connected to the sides of the clamping plate and the curved plate that are close to each other. When the clamping plate contacts the camera base, the clamping plate deforms, thereby wrapping the camera base. At the same time, the spring plates support the two ends of the clamping plate, causing the two ends of the clamping plate to bend, thereby better wrapping the camera base and assisting the clamping plate in fixing the camera base, improving the fixing effect.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention features an outer shell that suspends a platform from the bottom of a power line inspection drone via hooks. A camera for power line inspection is placed inside the shell. The shell is cone-shaped with a streamlined outer surface, reducing air resistance when the drone carries it, thus preventing any impact on the drone's flight efficiency. Symmetrical fixing rods are provided on both sides of the suspension arm to enhance the connection strength between the suspension arm and the platform, preventing bending of the suspension arm due to air resistance and thus avoiding shell swaying that could affect the inspection results.

[0015] This invention addresses the issue of damage to the outer casing caused by rain corrosion or impacts during prolonged use. The damaged casing vibrates during flight due to airflow, affecting the recording performance of the camera inside. By incorporating a spring, the vibration of the casing causes the second ring to vibrate, transmitting the vibration to the spring and causing it to deform. This deformation cushions the casing, reducing vibration. Furthermore, the spring's shape—thicker at both ends and thinner in the middle—ensures overall elasticity while allowing for easier deformation in the center, thus improving the spring's cushioning sensitivity and further enhancing the inspection performance of the camera inside the casing.

[0016] This invention, by setting a limiting component and incorporating a locking plate and a sliding plate, prevents rotation between the first and second ring bodies. The second ring body restricts the torsion of the outer casing, further preventing camera shake inside the casing and improving inspection efficiency. The elliptical grooves make the sides of the buffer plate thinner, allowing it to deform more easily. When the outer casing shakes, it causes the second ring body to shake, further causing the sliding plate to slide within the locking plate, thus compressing the buffer plate. The elastic force of the buffer plate limits the distance between the first and second ring bodies, preventing excessive spring deformation and damage, thereby extending the device's lifespan.

[0017] This invention, through the setting of a placement mechanism, improves the fixing effect by increasing the friction between the camera base and the clamp plate when the clamp plate contacts the camera base. The anti-slip groove is serpentine, increasing the contact area between the anti-slip groove and the camera base, thus assisting the clamp plate in fixing the camera base and further preventing camera shaking from affecting the inspection effect. When the clamp plate contacts the camera base, it deforms, thus wrapping around the camera base. Simultaneously, a spring plate supports both ends of the clamp plate, causing the ends to bend, further wrapping around the camera base and assisting the clamp plate in fixing the camera base, thus improving the fixing effect.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose. Example 1

[0028] Please see Figures 1-6This invention relates to an auxiliary suspension device for a power line inspection aircraft, comprising a suspension platform 1, with several hook seats 2 arranged at the corners of the suspension platform 1, the hook seats 2 being fixedly connected to the top of the suspension platform 1, and a platform body 5 being fixedly connected to the side of the suspension platform 1 away from the hook seats 2. The auxiliary suspension device for the power line inspection aircraft also includes a suspension mechanism 3, which is composed of suspension arms 31, which are symmetrically arranged on both sides of the platform body 5. The sides of the two suspension arms 31 that are close to each other are fixedly connected to the surface of the platform body 5. Fixing rods 32 are symmetrically arranged on both sides of the suspension arms 31, the sides of the two fixing rods 32 that are close to each other are fixedly connected to the surface of the suspension arms 31, and the ends of the fixing rods 32 that are away from the suspension arms 31 are fixedly connected to the surface of the platform body 5. A fixing seat 33 is fixedly connected to the end of the suspension arm 31 that is away from the platform body 5. A connecting plate 34 is fixedly connected to the inner wall of the fixing seat 33, and a first stabilizing plate 36 and a second stabilizing plate 37 are fixedly connected to both sides of the connecting plate 34, respectively.

[0029] A placement mechanism 4 is provided on the side of the connecting plate 34 away from the fixed base 33. The placement mechanism 4 includes a housing 41. The outer surface of the housing 41 is fixedly connected to the end of the first stabilizing plate 36 and the second stabilizing plate 37 away from the connecting plate 34. The housing 41 is set in a conical shape. The suspension platform 1 is suspended on the bottom of the power inspection aircraft through the hook seat 2. The camera used for power inspection is placed inside the housing 41. The housing 41 is set in a conical shape and has a streamlined outer surface. When the UAV carries the housing 41, it can reduce air resistance, thereby avoiding affecting the flight efficiency of the aircraft. Fixed rods 32 are symmetrically arranged on both sides of the hanging arm 31, thereby improving the connection strength between the hanging arm 31 and the platform 5, avoiding bending of the hanging arm 31 under the influence of air resistance, and thus avoiding the shaking of the housing 41 from affecting the inspection effect.

[0030] A compensation component 35 is provided at the interval between the two hanging arms 31. The compensation component 35 includes a frame 351, which is fixedly connected to the side of the platform 5 away from the suspension platform 1. A first ring 354 is fixedly connected to the side of the frame 351 away from the platform 5. A spring 355 is fixedly connected to the inner wall of the first ring 354, and the diameter of the spring 355 gradually decreases from both ends to the middle. A second ring 356 is fixedly connected to the end of the spring 355 away from the first ring 354, and several springs 355 are arranged along the circumference of the second ring 356. The inner wall of the second ring 356 is fixedly connected to the outer surface of the outer shell 41. During long-term use, the outer shell 41 will be affected by rain. Water corrosion or impact damage can cause the damaged outer shell 41 to vibrate during flight due to airflow. This vibration can affect the imaging effect of the camera inside the outer shell 41. By setting a spring 355, when the outer shell 41 vibrates, it drives the second ring 356 to vibrate. The vibration is transmitted to the spring 355, which deforms, thereby buffering the outer shell 41 and reducing its vibration. At the same time, the spring 355 is designed to be thick at both ends and thin in the middle, which ensures the overall elasticity of the spring 355 while making the middle part of the spring 355 easier to deform, thereby improving the buffering sensitivity of the spring 355 and further improving the inspection effect of the camera inside the outer shell 41.

[0031] A first reinforcing rod 352 is horizontally arranged on the inner wall of the frame 351. Both ends of the first reinforcing rod 352 are fixedly connected to the inner wall of the frame 351. Several second reinforcing rods 353 are also arranged inside the frame 351. The second reinforcing rods 353 are arranged perpendicular to the first reinforcing rods 352, and all the second reinforcing rods 353 are fixedly connected to the inner wall of the frame 351. By setting the second reinforcing rods 353 and the first reinforcing rods 352, the strength of the frame 351 is improved, and the vibration of the frame 351 caused by air resistance is prevented from causing the spring 355 to deform, thereby ensuring the buffering effect of the spring 355.

[0032] Limiting components 357 are provided at the interval between the first ring body 354 and the second ring body 356. The limiting components 357 are provided at the interval between a plurality of springs 355, and a plurality of limiting components 357 are provided along the circumference of the second ring body 356.

[0033] The limiting component 357 includes a locking plate 3571, and two locking plates 3571 are symmetrically arranged. The two locking plates 3571 are fixedly connected to the inner wall of the first ring body 354. A sliding plate 3572 is slidably connected at the interval between the two locking plates 3571. By setting the locking plates 3571 and the sliding plate 3572, the first ring body 354 and the second ring body 356 will not rotate. Thus, the second ring body 356 restricts the torsion of the outer shell 41, thereby further preventing the camera inside the outer shell 41 from shaking and improving the inspection effect.

[0034] A fixing strip 3573 is symmetrically arranged at the interval between the first ring body 354 and the sliding plate 3572. The sides of the two fixing strips 3573 that are far apart from each other are fixedly connected to the inner wall of the first ring body 354 and the end of the sliding plate 3572, respectively. A buffer plate 3574 is arranged at the interval between the two fixing strips 3573. The two ends of the buffer plate 3574 are fixedly connected to the sides of the two fixing strips 3573 that are close to each other, respectively. Several buffer plates 3574 are provided. An elliptical groove 3 is formed on the outer surface of the buffer plate 3574. 575, by opening the elliptical groove 3575, the two sides of the buffer plate 3574 are made thinner, making the buffer plate 3574 easier to deform. When the outer shell 41 shakes, it drives the second ring 356 to shake, which in turn drives the slide plate 3572 to slide inside the clamping plate 3571, thereby squeezing the buffer plate 3574. Under the elastic force of the buffer plate 3574, the distance between the first ring 354 and the second ring 356 is limited, thereby avoiding excessive deformation of the spring 355 and causing damage, thus improving the service life of the device. Example 2

[0035] Please see Figures 7-8 The housing 41 has a placement platform 42 inside, and the outer surface of the placement platform 42 is fixedly connected to the inner wall of the housing 41. A limiting groove 43 is formed on the surface of the placement platform 42, and a slider 44 is slidably connected to the inner wall of the limiting groove 43. A placement plate 45 is fixedly connected to the side of the slider 44 away from the placement platform 42, and the placement plate 45 is slidably connected to the surface of the placement platform 42. A first telescopic rod 46 is fixedly connected to the inner wall of the limiting groove 43. The end of the first telescopic rod 46 away from the limiting groove 43 is fixedly connected to the surface of the slider 44. When placing the camera, the first telescopic rod 46 is activated, and the first telescopic rod 46 extends, driving the slider 44 to move. The movement of the slider 44 drives the placement plate 45 to move, and the placement plate 45 leaves the inside of the housing 41, thus facilitating the placement of the camera. The first telescopic rod 46 retracts, and the placement plate 45 enters the inside of the housing 41, thereby blocking dust and rainwater from the outside of the housing 41 and protecting the camera.

[0036] The placement plate 45 is symmetrically provided with two telescopic rods 47. The ends of the two telescopic rods 47 that are far apart from each other are fixedly connected to the inner side of the placement plate 45. The ends of the two telescopic rods 47 that are close to each other are fixedly connected to two curved plates 48. The two ends of the curved plates 48 are fixedly connected to two fixed plates 410. A clamping plate 411 is provided at the interval between the two curved plates 48. The two ends of the clamping plate 411 are rotatably connected to the two fixed plates 410 respectively. When fixing the camera, the second telescopic rods 47 are activated, the second telescopic rods 47 extend, drive the curved plates 48 to move, and further drive the two clamping plates 411 to move closer to the camera base, thereby fixing the camera base.

[0037] The clamping plate 411 has an anti-slip groove 412 on the side away from the curved plate 48. There are several anti-slip grooves 412, and the anti-slip grooves 412 are serpentine. When the clamping plate 411 contacts the camera base, the anti-slip grooves 412 increase the friction between the camera base and the clamping plate 411, thereby improving the fixing effect. At the same time, the serpentine shape of the anti-slip grooves 412 increases the contact area between the anti-slip grooves 412 and the camera base, thereby assisting the clamping plate 411 in improving the fixing effect on the camera base and further preventing the camera from shaking and affecting the inspection effect.

[0038] A sliding rod 49 is fixedly connected to the side of the curved plate 48 away from the clamping plate 411. Two sliding rods 49 are symmetrically arranged, and the outer surface of the sliding rod 49 is slidably connected to the inner wall of the placement plate 45. A spring plate 413 is symmetrically arranged at the interval between the clamping plate 411 and the curved plate 48. The two ends of the spring plate 413 are fixedly connected to the sides of the clamping plate 411 and the curved plate 48 that are close to each other. When the clamping plate 411 contacts the camera base, the clamping plate 411 deforms, thereby wrapping the camera base. At the same time, the spring plate 413 supports the two ends of the clamping plate 411, causing the two ends of the clamping plate 411 to bend, thereby better wrapping the camera base and assisting the clamping plate 411 in fixing the camera base, improving the fixing effect.

[0039] In use, firstly, the first telescopic rod 46 is activated, and the first telescopic rod 46 extends, driving the slider 44 to move. The slider 44 moves, driving the placement plate 45 to move. The placement plate 45 leaves the inside of the housing 41, making it easier to put the camera in. When fixing the camera, the second telescopic rod 47 is activated, and the second telescopic rod 47 extends, driving the bending plate 48 to move. This further drives the two clamping plates 411 to move closer to the camera base, thereby fixing the camera base. The first telescopic rod 46 retracts, and the placement plate 45 enters the inside of the housing 41.

[0040] Then, the suspension platform 1 is suspended at the bottom of the power inspection drone via the hook seat 2. The camera used for power inspection is placed inside the outer shell 41. When the drone carries the outer shell 41, it can reduce air resistance. At the same time, during long-term use, the outer shell 41 may be damaged due to rain corrosion or collision. The damaged outer shell 41 will vibrate due to air flow during flight. When the outer shell 41 vibrates, it drives the second ring body 356 to vibrate. The vibration is transmitted to the spring 355, and the spring 355 deforms, thereby buffering the outer shell 41 and reducing the vibration of the outer shell 41. When the outer shell 41 shakes, it drives the second ring body 356 to shake, which further drives the slide plate 3572 to slide inside the clamping plate 3571, thereby squeezing the buffer plate 3574. Under the elastic force of the buffer plate 3574, the distance between the first ring body 354 and the second ring body 356 is limited, thereby avoiding excessive deformation of the spring 355 and causing damage.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
