Description

Technical Field

[0001] This invention relates to the field of insulator pollution detection technology, and more particularly to an insulator pollution detection device based on a hyperspectral camera. Background Technology

[0002] Insulator contamination is a significant factor affecting the stable operation of transmission lines. Maintenance personnel must regularly conduct insulator contamination tests and clean or replace insulators according to their contamination levels to ensure their insulation performance. Currently, insulator contamination testing primarily utilizes a "drone + spectral image analysis" system. Personnel control the drone from the ground to fly to a designated location, taking multi-angle, all-around photos of the insulators. Software then analyzes the photos to determine the contamination level. While the detection system employs a hyperspectral camera, this camera generates substantial heat during operation, potentially causing damage. Furthermore, dust adheres to the lens of the hyperspectral camera during high-altitude shooting, and the presence of water vapor and dust in the air further negatively impacts the captured images.

[0016] The present invention has the following beneficial effects:

[0017] (1) The device of the present invention has a cleaning tube and a drive assembly on the outside of the detection body for detecting insulator contamination. The drive assembly includes a fan blade, a second rotating rod, and a drive frame. The fan blade rotates under the drive frame, and the generated airflow can quickly dissipate heat from the detection body, preventing the detection body from being damaged by the high temperature generated during operation. The air inlet of the cleaning tube is located below the fan blade, and the air outlet is located at the edge of the detection lens of the detection body. The airflow generated when the fan blade rotates carries away the heat generated by the detection body and blows the generated hot air into the cleaning tube. The cleaning tube transfers the hot air to the detection lens and blows away the dust on the lens. At the same time, it heats the lens, preventing water mist from forming on the lens surface due to low temperature, enhancing the cleanliness of the lens, and ensuring the detection effect when detecting insulator contamination.

[0018] (2) The device of the present invention has a photovoltaic panel on the protective frame. The photovoltaic panel can generate electricity using light energy to power the detection subject and the drone, thereby increasing the device's endurance. This allows the detection device to perform pollution detection on the surface of the insulator for a long time without repeated charging, thus improving the detection efficiency of the device.

[0019] (3) A cleaning component is provided on the photovoltaic panel of the present invention. The dust on the surface of the photovoltaic panel can be cleaned by the cleaning component, so that the surface of the photovoltaic panel is not easily affected by dust and thus its normal power generation efficiency.

[0020] (4) The device of the present invention is provided with a collision protection plate, a first spring, a second spring, a third spring, a fixed shell, a limiting plate, a sliding rod and a buffer plate on the outside of the detection body. When the two sides of the detection body are hit by a foreign object, the two collision protection plates are driven to move closer to each other through the sliding rod. Multiple third springs are compressed, the fixed shell and the limiting plate move closer to each other, and multiple first springs and second springs are compressed. The compressed first spring, second spring and third spring cooperate with each other to absorb the impact force generated when the foreign object hits. At the same time, the protective frame can protect the front and rear of the detection component, so that the detection component is not easily damaged by the impact of the foreign object, and ensures the safety and stability of the detection component.

Detailed Implementation

[0029] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] refer to Figure 1 and Figure 2 The present invention provides an insulator pollution detection device based on a hyperspectral camera, including a drone 1, a detection component 6 for capturing images of insulator pollution is provided below the drone 1, a protective component 2 for protecting the detection component 6 is provided on the side of the detection component 6, and a driving component 7 is provided above the detection component 6.

[0031] refer to Figure 3 The detection component 6 includes a detection body 61, a baffle 62 and a cleaning tube 63. The baffle 62 is located below the detection body 61 and is fixedly connected to the outer wall of the detection body 61. The detection body 61 is a hyperspectral camera, and the bottom of the camera is a detection lens for detecting dirt on the insulator.

[0032] The cleaning tube 63 is a curved cylindrical tube extending through both ends and is installed on the detection body 61. One end is the air inlet, and the other end is the air outlet. The air inlet is located below the drive assembly 7, receiving the airflow generated by the drive assembly 7. The air outlet of the cleaning tube 63 is located at the edge of the detection lens of the detection body 61. The airflow is guided to the lens through the cleaning tube 63, causing the airflow to blow away dust from the lens and keep the lens clean. The cleaning tube 63 is made of antistatic polyvinyl chloride, which has a certain high-temperature resistance while shielding against static electricity in the air, which is beneficial for dust prevention.

[0033] The detection component 6 is equipped with a dustproof net 12, which filters out dust from the airflow blowing towards the detection body 61, ensuring that the detection component 6 is always in a relatively clean environment. The dustproof net 12 is made of high-polymer composite material, and the mesh diameter is no more than 2.5 micrometers.

[0034] refer to Figure 3 and Figure 5 The drive assembly 7 includes a second rotating rod 72, fan blades 73, a rotating block 74, and a drive frame 75. The fan blades 73 are rotatably connected to the bottom end of the second rotating rod 72, and the rotating block 74 is fixedly connected to the top end of the second rotating rod 72. Multiple drive frames 75 are connected to the outer wall of the rotating block 74. A wind-driven plate is connected to the end of each drive frame 75. When there is airflow, the wind-driven plate drives the drive frame 75 to rotate around the second rotating rod 72 under the action of the airflow. The fan blades 73 connected to the bottom end of the second rotating rod 72 also rotate accordingly. The rotation of the fan blades 73 generates a downward airflow, which carries away the heat generated by the detection body 61 during operation, assisting in the heat dissipation of the detection body 61. The fan blades 73 have an arc-shaped structure; their specific shape can refer to the structure of fan blades in commercially available electric fans to ensure that the generated airflow is directed towards the detection assembly 6. The wind-driven plate is hemispherical and hollow inside, and is connected to the drive frame 75.

[0035] refer to Figure 3 The protective component 2 includes a protective frame 21 and a support plate 22. The protective frame 21 has a frame structure and is connected to the lower part of the UAV 1 by screws at the top. The support plate 22 includes two pieces, which are vertically set on the left and right sides of the protective frame 21 respectively. The support plate 22 is a flat plate and is bonded to the protective frame 21 with strong adhesive.

[0036] The upper side of the two support plates 22 is provided with a first fixing component 4, and the lower side is provided with a second fixing component 5. The support plates 22 are connected to the first fixing component 4 and the second fixing component 5 respectively through the adjusting component 3.

[0037] The adjustment assembly 3 includes a telescopic rod 31, a movable plate 32, a connecting plate 33, a first rotating rod 34, and a buffer plate 35. The two movable plates 32 are respectively horizontally arranged outside the upper and lower sides of the support plate 22 and connected by four telescopic rods 31. The movable plates 32 are glued to the side of the connecting plate 33. The movable plates 32 are respectively connected to the first fixing assembly 4 and the second fixing assembly 5.

[0038] The buffer plate 35 is vertically arranged inside the support plate 22 and parallel to the support plate 22. Two first rotating rods 34 are respectively connected to the upper and lower side walls of the buffer plate 35. The other end of the first rotating rod 34 is connected to the movable plate 32 by a pin. The movable plate 32 and the first rotating rod 34 are hinged.

[0039] A buffer assembly 11 is connected to the outer wall of the buffer plate 35. The buffer assembly 11 includes a crash plate 112 and a slide bar 111. The crash plate 112 is located on the outside of the support plate 22 to protect the internal detection assembly 6. The length and width of the crash plate 112 both exceed the length and width of the detection assembly 6.

[0040] The slide bar 111 is fixed on the anti-collision plate 112 and one end of it passes through the support plate 22 and is connected to the outer wall of the buffer plate 35. A third spring 113 is provided between the support plate 22 and the anti-collision plate 112. The third spring 113 is sleeved on the slide bar 111. When the anti-collision plate 112 is compressed, the third spring 113 is compressed, and the impact on the anti-collision plate 112 can be absorbed by the third spring 113.

[0041] refer to Figure 5 and Figure 6 The protective frame 21 is equipped with a photovoltaic panel 8, and the photovoltaic panel 8 is equipped with a cleaning component 9.

[0042] The cleaning assembly 9 includes a third rotating rod 92, a rotating plate 93, and a cleaning plate 94. The third rotating rod 92 is rotatably connected to the photovoltaic panel 8 via a second bearing 91. The rotating plate 93 is connected to the top of the third rotating rod 92. The cleaning plate 94 is disposed on the lower surface of the rotating plate 93 and is in contact with the upper surface of the photovoltaic panel 8. The cleaning plate 94 can remove dust from the photovoltaic panel 8. To prevent the photovoltaic panel 8 from being scratched, the cleaning plate 94 is made of sponge and is adhered to the lower surface of the rotating plate 93.

[0043] refer to Figure 7The bottom end of the third rotating rod 92 is connected to a transmission assembly 10. The transmission assembly 10 includes a first pulley 101 and a second pulley 103 connected to the first pulley 101 via a belt 102. There are two second pulleys 103 (two for the photovoltaic panel 8). The two second pulleys 103 are connected to the third rotating rod 92. An electric push rod 104 is engaged inside the first pulley 101. The bottom end of the electric push rod 104 is connected to a locking block 105. The rotating block 74 has an upward-facing locking groove 76. The locking block 105 is located directly above the locking groove 76. The shape and size of the locking block 105 are adapted to the locking groove 76. When the locking block 105 is engaged in the locking groove 76, the rotating block 74 can drive the first pulley 101 to rotate through the locking block 105. At this time, the rotation of the fan blade 73 not only relies on natural airflow, but can also be driven to rotate by the electric push rod 104, so that there is always a constant heat dissipation airflow on the outside of the detection assembly 6.

[0044] refer to Figure 3 The first fixing component 4 includes a fixing shell 41 and a first spring 42. The fixing shell 41 is located outside the detection component 6 and is connected to the detection component 6 through the first spring 42. The two sides of the fixing shell 41 are respectively connected to two connecting plates 33. The second rotating rod 72 is rotatably mounted on the fixing shell 41 through the first bearing 71, and the top end of the second rotating rod 72 extends out of the top plate of the fixing shell 41.

[0045] refer to Figure 4 The second fixing component 5 includes a limiting plate 51 and a locking rod 52 connected to the limiting plate 51. The two sides of the limiting plate 51 are respectively connected to the connecting plate 33. The upper end of the locking rod 52 is connected to the baffle 62. The baffle 62 and the limiting plate 51 are provided with a second spring 53, which is sleeved on the locking rod 52.

[0046] Working principle and usage process of the device of this invention:

[0047] When using the device, pull down the limiting plate 51. The limiting plate 51 drives the two buffer plates 35 away from each other through the two connecting plates 33 and the first rotating rod 34. The buffer plates 35 drive the slide rod 111 to slide in the support plate 22. The third spring 113 extends and retracts, and the detection body 61 moves towards the middle of the fixed shell 41, so that the top of the detection body 61 contacts the four first springs 42.

[0048] The bottom end of the detection body 61 is passed through the limiting plate 51. The four locking rods 52 on the limiting plate 51 are inserted into the baffle 62. The four second springs 53 contact the baffle 62. The limiting plate 51 is slowly released. The fixed shell 41 and the limiting plate 51 move closer to each other under the elastic force of the multiple third springs 113, thereby compressing the four first springs 42 and the four second springs 53. At this time, the detection body 61 is fixed between the limiting plate 51 and the fixed shell 41.

[0049] The drone 1 is controlled to operate, and the drone 1 moves the inspection body 61 to the vicinity of the insulator to inspect the dirt on the surface of the insulator. At the same time, multiple drive frames 75 drive the second rotating rod 72 to rotate under the action of wind. The second rotating rod 72 drives the fan blade 73 to rotate. The airflow generated by the fan blade 73 passes through the dustproof net 12 and blows the heat generated inside the inspection body 61 during operation into the air inlet of the two cleaning pipes 63. The hot air from the air outlet of the two cleaning pipes 63 blows off the dust on the inspection lens of the inspection body 61 and also heats the inspection lens of the inspection body 61.

[0050] The electric push rod 104 is extended, which drives the locking block 105 to move downward and into the slot 76. At this time, the rotating block 74 drives the first pulley 101 to rotate inside the photovoltaic panel 8 through the locking block 105 and the electric push rod 104. The rotating first pulley 101 drives the two second pulleys 103 to rotate through the two belts 102. The two rotating second pulleys 103 drive the two rotating plates 93 to rotate through the third rotating rod 92. The two rotating plates 93 drive the cleaning plate 94 to rotate, thereby cleaning the dust on the surface of the photovoltaic panel 8.

[0051] When the two sides of the detection body 61 are impacted by external objects, the two anti-collision plates 112 drive the four sliding rods 111 to slide within the support plate 22, and the third spring 113 retracts. At the same time, the eight sliding rods 111 drive the two buffer plates 35 to move closer to each other. The two buffer plates 35 that move closer to each other drive the four connecting plates 33 to move closer to each other through the four first rotating rods 34. The four connecting plates 33 that move closer to each other drive the four telescopic rods 31 to retract. The four connecting plates 33 that move closer to each other drive the fixed shell 41 and the limiting plate 51 to move closer to each other. The fixed shell 41 that moves downward drives the four first springs 42 to retract, and the limiting plate 51 that moves upward drives the four second springs 53 to retract. The retracted first springs 42, second springs 53 and third springs 113 work together to absorb the impact force generated when the external object hits. At the same time, the protective frame 21 can protect the front and rear of the detection component 6.

[0052] The above description is merely a preferred embodiment of the present invention, and does not represent all possible forms of the present invention. The scope of protection of the present invention is not limited to such specific statements and embodiments. Various other modifications and improvements can be made based on the technical teachings disclosed in the present invention without departing from the essence of the present invention, and these modifications and improvements are still within the scope of protection of the present invention.
