[0027] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0028] Figure 1 The specific structure of the inspection equipment used in the present invention is shown. Figure 1 As shown, the inspection device 2 is a patrol robot, comprising a body 2a, a support frame 2b vertically mounted on top of the body 2a, and two movable rollers 2c arranged side by side on the support frame 2b. The body 2a of the patrol robot 2 houses a drive motor (not shown) that drives the movable rollers 2c to rotate in the same direction. The outer sidewalls of the movable rollers 2c are provided with circumferential rolling grooves that engage with electrical cables, allowing the movable rollers 2c to slide along the cables, thereby enabling movement of the patrol device 2.

[0029] Figure 2 The specific structure of an embodiment of the inspection equipment online auxiliary device of the present invention is shown. Figure 2 As shown, in this embodiment, the inspection equipment online auxiliary device includes an aircraft 10 and an online auxiliary bracket 20 connected to the bottom of the aircraft 10, wherein the aircraft 10 is a drone, and the online auxiliary bracket 20 has a accommodating cavity 2004 inside for accommodating the inspection equipment 2.

[0030] Specifically, Figure 3 The figure shows the specific structure of an embodiment of the on-line auxiliary bracket in the on-line auxiliary device of the inspection equipment of the present invention. Figure 3As shown, the upper thread auxiliary bracket 20 is generally rectangular and includes a bracket body 200 and a hanging member 204. The bracket body 200 includes a rectangular horizontal portion 2000 and two vertical portions 2002 disposed perpendicularly at opposite ends of the horizontal portion 2000 along its length, respectively representing a first vertical portion and a second vertical portion. The horizontal portion 2000 and the two vertical portions 2002 of the bracket body 200 define a receiving cavity 2004, the bottom and two opposite sides of which along a first direction D1 are open. The length of the horizontal portion 2000 is a second direction D2, and the angle between the second direction D2 and the first direction D1 is 90°. The hanging member 204 is located within the receiving cavity 2004 and includes a pulley guide structure 2040a, which extends along the first direction D1. The upper surface of the card wheel guide structure 2040a protrudes upward to form an arc surface that is adapted to the circumferential rolling groove of the moving roller 2c of the inspection equipment 2, and is used to clamp the rolling groove of the moving roller 2c from the bottom, so that the moving roller can move along the first direction D1 along the upper surface of the card wheel guide structure 2040a; the lower surface of the card wheel guide structure 2040a forms a cable trough 2040b extending along the first direction D1 with the groove facing downward, and both ends of the cable trough 2040b along the first direction D1 are open structures, and the groove width of the cable trough 2040a is slightly larger than the width of the cable 3.

[0031] During the process of the online auxiliary bracket 20 hanging the cable 3, the first direction D1 is parallel to the extension direction of the cable 3. As the online auxiliary bracket 20 gradually approaches the cable 3 from above the cable 3, the cable 3 can enter the accommodating cavity 2004 from the bottom opening of the bracket body 200, and finally be accommodated in the cable trough 2040b, so that the online auxiliary bracket 20 is hung on the cable 3.

[0032] Specifically, if Figure 3 As shown, the thread-up auxiliary bracket 20 further includes a first connecting arm 201 and a second connecting arm 202 disposed opposite each other within the accommodating chamber 2004. The first connecting arm 201 is located at the upper portion of the accommodating chamber 2004, with one end fixed to the inner side of the first vertical portion and the other end being free. The second connecting arm 202 is located at the lower portion of the accommodating chamber 2004, with one end fixed to the inner side of the second vertical portion and the other end being free.

[0033] The hanging member 204 is a laminated plate, specifically comprising a hanging portion 2040, and a first connecting portion 2041 and a second connecting portion 2042 connected to the ends of the hanging portion 2040. The hanging portion 2040 is connected to the first connecting portion 2041 via a pulley guide structure 2040a. The hanging member 204 is secured within the accommodating chamber 204 via a first connecting arm 201 and a second connecting arm 202. Specifically, the first connecting portion 2041 of the hanging member 204 is connected to the free end of the first connecting arm 201, and the second connecting portion 2042 of the hanging member 204 is connected to the free end of the second connecting arm 202. Thus, the first connecting arm 201, the second connecting arm 202, and the hanging member 204 divide the accommodating chamber 2004 into a first area 2004a and a second area 2004b. The first area 2004a is used to accommodate inspection equipment.

[0034] Specifically, the shape of the hanging member 204 can be set according to the overall structure of the inspection device 2. In this embodiment, since the inspection device 2 is generally in an "L" shape that is narrow at the top and wide at the bottom, the hanging member 204 is preferably in an "S" shape. Specifically, the first connecting arm 201 is located at the top of the hanging member 204, and the second connecting arm 202 is located at the bottom of the hanging member 204. The two ends of the hanging portion 2040 are respectively connected to the first connecting arm 201 and the second connecting arm 202, thereby forming a first area 2004a that is narrow at the top and wide at the bottom to accommodate the inspection device 2.

[0035] Here, in order to reduce the overall weight of the upper thread auxiliary bracket 20, the bracket body 200, the first connecting arm 201 and the second connecting arm 202 can all adopt a hollow structure.

[0036] Figure 4 The specific structure of an embodiment of the patrol equipment online auxiliary device of the present invention is shown. Figure 4 As shown, before use, the inspection equipment 2 is first installed in the first area 2004a of the online auxiliary bracket 20. Specifically, the rolling groove of the movable roller 2c of the inspection equipment is clamped to the upper surface of the clamping wheel guide structure 2040a of the hanging part 204, and then the online auxiliary bracket 20 is fixed to the landing bracket 12 at the bottom of the aircraft 10.

[0037] Figure 5-6The schematic diagram shows the structure of the present invention's auxiliary line-up device, equipped with inspection equipment, attached to a cable line. During use, a control device (not shown) controls an aircraft 10 carrying an auxiliary line-up bracket 20 to fly above the cable line 3 to be inspected. The bottom opening of the bracket body 200 of the auxiliary line-up bracket 20 is aligned with the cable line 3, with the first direction D1 being parallel to the cable line 3. The aircraft 10 then gradually descends, allowing the cable line 3 to enter the bracket body 200 through the bottom opening and move along the guide channel of the second region 2004b into the cable duct 2040b, thereby attaching the auxiliary line-up bracket 20 to the cable line 3. Once the auxiliary line-up bracket 20 is securely attached to the cable line 3, a drive motor (not shown) within the body 2a of the inspection device 2 drives the movable roller 2c to rotate in the same direction, allowing the inspection device 2 to move from the side opening of the bracket body 200 to the cable line 3, and begin inspection. After the inspection equipment 2 is completely moved out of the online auxiliary bracket 20, the aircraft 10 gradually increases its altitude, and the cable 3 gradually approaches the bottom opening of the bracket body 200 along the wire channel until it is completely separated from the online auxiliary bracket 20. The aircraft 10 then flies back to the ground with the online auxiliary bracket 20 to prepare for the next online auxiliary work of the inspection equipment 2.

[0038] Here, because the inspection device 2 typically includes a locking device for the movable roller 2c, the movable roller 2c will not rotate without a driving force until the inspection device 2 is activated. Of course, the upper surface of the latching wheel guide structure 2040a may be coated with a material or provided with an anti-slip pad to increase friction between it and the movable roller 2c, thereby preventing the inspection device 2 from sliding while moving in the first direction D1 during flight of the aircraft 10. Furthermore, a limit post may be provided at the top of one end of the latching wheel guide structure 2040a along the first direction D1 to further prevent the inspection device 2 from sliding during flight.

[0039] Specifically, since the first connecting arm 201 and the second connecting arm 202 may constitute a movement obstacle to the cable 3 during the process of the auxiliary support 20 gradually descending from above the cable 3 and gradually approaching the cable 3, thus hindering the movement of the cable 3, it is necessary to manipulate the aircraft 10 to move horizontally or vertically to adjust the position of the auxiliary support 20 so that the cable 3 can bypass the first connecting arm 201 or the second connecting arm 202 and continue to move along the wire channel into the cable duct 2040b, which is difficult to operate. Therefore, in some embodiments, the first connecting arm 201 in the auxiliary support 20 is tilted, with its free end facing upward, and the second connecting arm 202 is also tilted, with its free end also facing upward. Thus, when the cable 3 touches the second connecting arm 202, the cable 3 can slide upward along the second connecting arm 201 from the bottom opening of the bracket body 200 into the second area 2004b. Similarly, when the cable 3 touches the first connecting arm 201, the cable 3 can continue to slide upward along the first connecting arm 201 until the cable 3 enters the cable trough 2040b. In this way, by tilting the first connecting arm 201 and the second connecting arm 202, the cable 3 can slide into the cable trough 2040b more smoothly.

[0040] Specifically, because the movable roller 2c of the inspection device 2 can only form a single-sided support when it is engaged with the upper surface of the latching wheel guide structure 2040a, this engagement is unstable and may cause the inspection device 2 to become loose during flight of the aircraft 10. Therefore, in some embodiments, the line-up auxiliary bracket 20 further includes a rod-shaped latching wheel member 206. The latching wheel member 206 is cylindrical and horizontally fixed within the first region 2004a and located directly above the latching wheel guide structure 2040a of the mounting member 204. The latching wheel member 206 is parallel to the latching wheel guide structure 2040a and extends in a first direction D1. The distance between the latching wheel member 206 and the latching wheel guide structure 2040a is greater than or less than the outer diameter of the movable roller 2c. This allows the rolling grooves on opposite sides of the movable roller 2c to engage with the latching wheel guide structure 2040a and the latching wheel member 206, respectively, thereby enabling the movable roller 2c to move along the latching wheel guide structure 2040a. Here, the clamping wheel 206 can be fixed to the inner side of the vertical portion 2002 of the bracket body 200 by a connecting member, or can be fixed to the inner side of the vertical portion 2002 of the bracket body 200 by a connecting member. Figure 3 and Figure 4 As shown, the connecting rod 205 is fixed to the inner side of the horizontal portion 2000 of the bracket body 200. As long as the clamping wheel member 206 is positioned above and parallel to the clamping wheel guide structure 2040a, it is sufficient. The clamping wheel member 206 provides a double-sided clamping connection with the movable roller 2c of the inspection device 2, thereby improving the stability of the clamping connection. Of course, the clamping wheel member 206 and the connecting rod can also be integrally formed.

[0041] Here, in order to achieve bilateral clamping of the movable roller 2c, the distance between the clamping wheel member 206 and the clamping wheel guide structure 2040a needs to be smaller than the outer diameter of the movable roller 2c. In order to install the movable roller 2c between the clamping wheel guide structure 2040a and the clamping wheel member 206, the connection between the first connecting arm 201 and the first connecting portion 2041 of the hanging member 204 in the above-mentioned upper line auxiliary bracket 20 needs to be detachably connected. Specifically, the first connecting portion 2041 is tilted downward, and the top surface of the free end of the first connecting portion 2041 abuts the bottom surface of the free end of the first connecting portion 201, so that the first connecting portion 2041 of the hanging member 204 is fixed to the bottom of the first connecting arm 201. Preferably, the top surface of the first connecting portion 2041 is parallel to the plane where the first connecting arm 202 is located. In this way, the contact area can be increased when the two abut, thereby improving the firmness of the clamping. When installing the inspection device 2, the wire groove at the lower end of the moving roller 2c can be engaged with the card wheel guide structure 2040, and then the wire groove of the moving roller 2c can be engaged with the card wheel member 206 to achieve longitudinal double-sided engagement of the moving roller 2c. Since the hanging member 204 is a lamellar plate, it has a certain degree of elasticity. Therefore, after the moving roller 2c is engaged with the card wheel guide structure 2040a and the card wheel member 206, the first connecting portion 2041 of the hanging member 204 is pressed down below the first connecting arm 201, so that the top surface of the free end of the first connecting portion 2041 abuts against the bottom surface of the first connecting arm 201. The elasticity of the hanging member 204 is utilized to fix the hanging member 204 and the first connecting arm 201. In this way, there is no need to set a locking member to fix the two, which is convenient to install and has low manufacturing cost.

[0042] Specifically, the connection between the second connecting arm 202 and the second connecting portion 2042 of the hanging member 204 can be a fixed connection such as welding, or a detachable connection. Specifically, the detachable connection involves the second connecting portion 2042 being tilted downward, with the bottom surface of the free end of the second connecting portion 2042 abutting against the top surface of the free end of the second connecting arm 202, so that the second connecting portion 2042 of the hanging member 204 is secured to the top of the second connecting arm 202. Preferably, the bottom surface of the second connecting portion 2042 is parallel to the plane of the second connecting arm 202. This increases the contact area when the two abut, enhancing the secureness of the connection. Since the first connecting portion 2041 and the second connecting portion 2042 of the hanging member 204 are detachably connected to the first connecting arm 201 and the second connecting arm 202, respectively, the hanging member 204 can be removed for easy maintenance or replacement with a hanging member 204 compatible with a different structure of the inspection device 2.

[0043] Of course, the detachable fixing method between the first connecting arm 201 and the first connecting portion 2041 and between the second connecting arm 202 and the second connecting portion 2042 can also be fixed by a locking assembly. Both methods have their advantages and disadvantages. Fixing with a locking assembly can improve the firmness, but it is not as convenient to install and has a higher manufacturing cost.

[0044] Specifically, the rod body of the connecting rod 205 has a telescopic structure (not shown in the figure), and the distance between the clamping wheel component 206 and the clamping wheel guide structure 2040a of the hanging component 204 is adjusted through the telescopic structure, thereby adjusting the clamping degree of the moving roller 2c.

[0045] In addition, although the above-mentioned online auxiliary device 1 realizes longitudinal double-sided clamping of the movable roller 2c by providing the clamping wheel member 206, which can improve the firmness of the clamping, since the inspection device 2 body 2a is relatively heavy and large in size, it is easy to cause the inspection device 2 body 2a to rock back and forth during the flight of the aircraft 10. Therefore, to prevent the inspection device 2 from rocking back and forth, in some embodiments, the online auxiliary bracket 20 also includes a rocking stop member 208. The rocking stop member 208 is located in the first area 2004a, one end of which is fixed to the inner side of the vertical portion 2002 of the bracket body 200, and the other end is a free end. The free end of the rocking stop member 208 abuts the inspection device 2 to provide support for the inspection device 2 in the lateral direction, thereby preventing the inspection device 2 from rocking during the flight of the aircraft 10 and improving stability. Here, the rocking stop member 208 can be cylindrical or square, or it can be an arc-shaped that bulges toward the inspection device 2. In this embodiment, the anti-sway member 208 is an arc-shaped frame or a circular frame protruding toward the inspection device 2. The arc-shaped or circular anti-sway member 208 has a single-point contact with the inspection device 2. On the one hand, it can avoid scratching the inspection device 2; on the other hand, it can prevent the anti-sway member 208 from getting stuck in the inspection device 2 when the inspection device 2 moves from the online auxiliary bracket 20 to the cable line 3, making it impossible for the inspection device 2 to be separated from the online auxiliary bracket 20.

[0046] In summary, compared to the prior art, the present invention uses an aircraft to carry an auxiliary support bracket carrying inspection equipment, and by hooking the auxiliary support bracket to the cable line of the power transmission and transformation equipment, the inspection equipment is transferred to the cable line. The entire process does not require manual handling, reducing labor intensity and improving work safety. At the same time, it avoids damage to the equipment caused by collisions between the inspection equipment and surrounding physical structures during manual handling. In short, the present invention has a simple structure, good economic efficiency, strong applicability, and can be applied to different geographical environments, making it worthy of promotion.

[0047] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
