Description

Technical Field

[0001] This utility model relates to the field of overhead transmission line maintenance technology, and in particular to an overhead transmission line inspection and foreign object removal device. Background Technology

[0002] As a key component of the power system, the safe and stable operation of overhead transmission lines is of paramount importance. Regular inspections and cleaning are necessary to promptly detect and address issues such as insulator damage, broken conductor strands, corrosion, and foreign objects like kites and plastic bags attached to the lines. Traditional maintenance methods primarily rely on manual tower climbing or live-line work, which inherently suffers from high labor intensity, low efficiency, and high safety risks.

[0003] With the development of automation technology, various inspection robots have begun to be applied to the maintenance of power transmission lines. Among them, inspection and cleaning devices that can move along the line body typically rely on wheels on their bodies to grip the conductors or ground wires, and are equipped with high-definition cameras, infrared thermal imagers, or mechanical grippers and other cleaning tools to perform tasks. This type of automated device greatly improves the safety and efficiency of the operation.

[0004] However, in winter or in frigid regions, a hard and irregular layer of ice easily forms on the surface of overhead transmission lines. Existing inspection and cleaning devices typically have wheels designed for direct contact with the smooth cable surface. When the cable is covered with ice, it becomes difficult for the wheels to maintain a stable and effective grip, significantly reducing friction. This can lead to slippage, violent shaking, or even complete immobility of the device during operation.

[0005] The instability during movement directly leads to the failure of inspection and cleaning functions. For example, the shaking of the machine can blur the images captured by the camera, making it impossible to accurately identify line defects; it can also cause the foreign object cleaning mechanism to misposition, making it unable to accurately complete the grabbing or removal operation. Therefore, how to effectively solve the problem of stable movement of the device on icy cables is the core technical bottleneck to ensure its reliable operation in all weather and all regions.

[0006] Therefore, this utility model proposes a foreign object removal device for overhead transmission line inspection to address the shortcomings of existing technologies. Utility Model Content

[0007] In view of the technical defects in the existing technology of foreign object removal devices for overhead transmission line inspection, when traveling on icy cables, the moving wheels are prone to slipping and shaking, which makes the device unable to operate stably, resulting in distorted inspection data and failure of foreign object removal operations. This utility model aims to provide an overhead transmission line inspection foreign object removal device with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a foreign object removal device for inspecting overhead transmission lines, including: a body and movable wheels installed on the body; the device also includes an ice-breaking component disposed on the body.

[0009] The innovative structure of the ice-breaking component includes a first outer shell and an ice-breaking drive motor mounted on the first outer shell. An active shaft is rotatably connected inside the first outer shell, and this active shaft is connected to the output end of the ice-breaking drive motor. A drive gear is fixedly connected to the active shaft. A driven shaft is also rotatably arranged inside the first outer shell, and a reduction gear and a driven gear, meshing with the drive gear, are fixedly connected to the driven shaft. A transmission rack is slidably arranged inside the first outer shell, and this transmission rack meshes with the driven gear to convert rotational motion into linear motion. A pressing plate and a cone are fixedly connected to one end of the transmission rack. This combined structure mechanically breaks up the ice layer on the cable surface.

[0010] Preferably, in order to enable the extrusion plate to better conform to the cable profile and achieve flexible extrusion, the extrusion plate is provided with a movable hinge.

[0011] Preferably, in order to ensure that the ice-breaking component itself is not blocked by ice debris generated during operation, thereby ensuring that the device can operate reliably for a long time, the overhead transmission line inspection foreign object cleaning device also includes a cleaning component installed on the body for cleaning the ice-breaking component.

[0012] As a specific embodiment of the cleaning component, the cleaning component includes a second housing and a cleaning drive motor mounted on the second housing; a power shaft is rotatably connected inside the second housing, the power shaft is driven by the cleaning drive motor, and a power gear is fixedly connected to the power shaft; a linkage rack that meshes with the power gear is also slidably arranged inside the second housing; furthermore, an output shaft is rotatably arranged inside the second housing, and a steering gear that meshes with the linkage rack and a cleaning brush for performing the cleaning action are fixedly connected to the output shaft, thereby forming a complete automated cleaning transmission chain.

[0013] This utility model has the following beneficial effects: 1. This utility model solves the technical problem that existing inspection devices cannot move stably due to ice formation on the cable surface, resulting in distorted inspection data and misaligned foreign object removal. It solves the technical effects of automated ice breaking, ensuring stable operation of the device on the cable, and improving the accuracy of subsequent operations by setting up an ice-breaking component consisting of an ice-breaking drive motor, a reduction gear set, a transmission rack, and an extrusion plate.

[0014] 2. This utility model, by adding a cleaning component consisting of a slag removal drive motor, a transmission mechanism, and a cleaning brush, is used to automatically remove residual ice slag on the ice-breaking component. This solves the technical problem that the accumulation of ice fragments may clog the ice-breaking mechanism, causing the device to malfunction and stop. It achieves the technical effect of self-maintaining the functional modules and ensuring long-term continuous and stable operation of the whole machine in severe cold environments.

[0015] 3. The overall structure of this utility model is ingeniously designed. Both the ice-breaking component and the cleaning component adopt a transmission method of motor and gear rack. Compared with complex systems such as hydraulic or pneumatic, it has the advantages of compact structure, reliable transmission and easy maintenance. It is especially suitable for stable operation in low temperature environment, which improves the practicality and automation level of the device. Attached Figure Description

[0019] Example: Please refer to Figures 1 to 4 This utility model provides a foreign object removal device for overhead transmission line inspection, which aims to solve the technical problem that existing inspection devices are prone to slipping and shaking in icy winter environments, and the ice slag produced after breaking the ice can easily clog the device, resulting in the inability to operate continuously.

[0020] like Figure 1 and Figure 2 As shown, the overhead transmission line inspection foreign object removal device includes a body 1; a moving wheel 4 is installed on the body 1; the device also includes an ice-breaking component 2 installed on the body 1; the device also includes a cleaning component 3 installed on the body 1 for cleaning the ice-breaking component 2; Specifically, such as Figure 1 and Figure 3 As shown, the ice-breaking assembly 2 includes a first housing 211; an ice-breaking drive motor 21 is mounted on the first housing 211; an active shaft 22 is rotatably connected inside the first housing 211; the active shaft 22 is connected to the output end of the ice-breaking drive motor 21; and an active gear 23 is fixedly connected to the active shaft 22.

[0021] Please refer to the following carefully. Figure 3 A driven shaft 25 is rotatably disposed inside the first housing 211; a reduction wheel 24 is fixedly connected to the driven shaft 25 and meshes with the driving gear 23; a driven gear 26 is fixedly connected to the driven shaft 25; a transmission rack 27 is slidably disposed inside the first housing 211 and meshes with the driven gear 26; a pressing plate 28 and a cone 210 are both fixedly connected to one end of the transmission rack 27.

[0022] As a further limitation of this embodiment, please refer to Figure 3 The extrusion plate 28 is provided with a movable hinge 29.

[0023] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred implementation method, please refer to Figure 1 and Figure 4The overhead transmission line inspection foreign object cleaning device also includes a cleaning component 3 installed on the body 1 for cleaning the ice-breaking component 2; the cleaning component 3 includes a second housing 38 and a slag-cleaning drive motor 31 installed on the second housing 38; in order to realize the cleaning function, a power shaft 32 is rotatably connected inside the second housing 38, and the power shaft 32 is connected to the output end of the slag-cleaning drive motor 31; a power gear 33 is fixedly connected to the power shaft 32; a linkage rack 34 is slidably installed inside the second housing 38 and meshes with the power gear 33; a steering gear 35 is fixedly connected to the output shaft 36 rotatably installed inside the second housing 38, and the steering gear 35 meshes with the linkage rack 34; a cleaning brush 37 is fixedly connected to the output shaft 36.

[0024] The working principle of this utility model's overhead transmission line inspection foreign object removal device is as follows: When the cleaning device operates on the iced cable surface, the ice-breaking drive motor 21 of the ice-breaking component 2 is activated. The ice-breaking drive motor 21 then drives the active shaft 22 to rotate. The active shaft 22 drives the active gear 23 fixedly connected to it to rotate. The active gear 23 meshes with and drives the reduction wheel 24 to rotate. Since the reduction wheel 24 and the driven gear 26 are both fixedly connected to the driven shaft 25, the reduction wheel 24 drives the driven gear 26 to rotate synchronously through the driven shaft 25. When the driven gear 26 rotates, it meshes with the transmission rack 27 to generate displacement. While the transmission rack 27 drives the extrusion plate 28 and the cone 210 to move together, it pulls the extrusion plate 28 to bend at the bend with the help of the movable hinge 29. During the entire transmission process, the first outer shell 211 plays a limiting and guiding role for the gear set. Finally, the ice layer on the cable surface is broken by the mutual extrusion of the two sets of transmission racks 27 and the externally connected extrusion plate 28 and cone 210.

[0025] When ice residue remains on the outside of the ice-breaking component 2 of the cleaning device, the cleaning drive motor 31 of the cleaning component 3 is activated. The cleaning drive motor 31 then drives the power shaft 32 and the power gear 33 fixedly connected thereon to rotate synchronously. After the power gear 33 rotates, it meshes and drives the linkage rack 34 to generate displacement. During the displacement of the linkage rack 34, it meshes and drives the steering gear 35 and the output shaft 36 to rotate together. The output shaft 36 then drives the cleaning brush 37 fixedly connected thereon to rotate. The entire operation process is limited and guided by the second housing 38. Finally, the cleaning operation of the ice residue remaining on the outside of the ice-breaking component 2 of the cleaning device is completed by the rotation of the cleaning brush 37.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
