[0025] The present invention will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present invention in a schematic manner, so they only show the components related to the present invention.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Figure 1 、 Figure 2 and Figure 3 As shown in Figure 2 and Figure 3 , an early warning device for major discharge defects is provided, which includes a horizontal base 1. An electrically controlled assembly housing 2 is movably assembled on the lower surface of the horizontal base 1. End electric drive wheel sets 3 are movably assembled on both sides of the upper surface of the horizontal base 1. Lateral storage grooves 4 are symmetrically formed on both sides of the lower surface of the horizontal base 1. A flip - type lateral adjustment arm 5 is movably assembled inside the lateral storage grooves 4. The non - movable connection end of the flip - type lateral adjustment arm 5 is connected to an electrically controlled assembly seat 6 with an adjustable angle. An electrically controlled screw lifting module 7 is installed inside the electrically controlled assembly seat 6. An optical detection module 9 is installed on the inner wall of the electrically controlled assembly housing 2 through an embedded sliding seat 8.

[0028] For the sake of lateral assembly, on both upper ends of the horizontal base 1, there are laterally assembled frames 10 with an integrally protruding structure. The end electric drive wheel sets 3 are connected to the laterally assembled frames 10 by inserting lateral assembly shafts into the interiors of the laterally assembled frames 10.

[0029] When the flip - type lateral adjustment arm 5 flips outward, the flip - type lateral adjustment arm 5 will be arranged inside the lateral assembly frames 10 on both sides, so that a staggered layout can be formed to avoid mutual interference between structures.

[0030] The entire device is powered by a power battery, which is installed inside the horizontal base 1 to supply power to the electronic components on the entire device.

[0031] This device can adopt two forms: no - load and ground - load. In the no - load mode, the end electric drive wheel set 3 and the electric control screw lifting module 7 face upward, and the electric control screw lifting module 7 rotates at high speed for suspended detection; in the ground - load mode, the end electric drive wheel set 3 faces downward, and the end electric drive wheel set 3 supports at the bottom for ground - load detection.

[0032] To cooperate with lateral assembly, lateral assembly grooves 11 with open bottoms are provided on both side walls of the horizontal base 1.

[0033] To cooperate with the outer flip - adjustment, the electric - control assembly housing 2 includes an arc - shaped first housing 21 with a flip - connection head at the upper end, an arc - shaped second housing 22 with a flip - connection head at the upper end, and a lateral adjustment strut 23. The flip - connection head is movably assembled with the horizontal base 1 by inserting two - side rotating shafts into the mounting blind holes on the inner wall of the lateral assembly groove 4.

[0034] The lateral adjustment strut 23 performs telescopic adjustment. The lateral adjustment strut 23 controls the arc - shaped first housing 21 and the arc - shaped second housing 22 to flip downward through extension, so as to close the bottom opening. In this way, the entire device wraps the cable on the outside to prevent the device from falling.

[0035] To facilitate movable assembly and flip - folding storage, one end of the flip - type lateral adjustment arm 5 is movably assembled with the lateral storage groove 4 by inserting two - side mounting shafts into the mounting blind holes at the inner end of the lateral storage groove 4. The lower opening of the lateral storage groove 4 has arc - shaped limit blocks for enhancing the storage firmness of the flip - type lateral adjustment arm 5.

[0036] When unfolded, the flip - type lateral adjustment arm 5 flips outward and flips the flip - type lateral adjustment arm 5 to both sides of the horizontal base 1; when stored, the flip - type lateral adjustment arm 5 flips inward and flips the flip - type lateral adjustment arm 5 to the inside of the lateral storage groove 4 for storage.

[0037] To cooperate with angle adjustment, a lateral assembly blind hole is provided at the non - movable connection end of the flip - type lateral adjustment arm 5. The electric - control assembly seat 6 includes an end - adjustment motor 61 axially inserted into the lateral assembly blind hole and a rotation - adjustment seat 62 axially fixed on the adjustment shaft outside the end - adjustment motor 61.

[0038] The end - adjustment motor 61 drives the rotation - adjustment seat 62 to perform rotation adjustment, so as to change the angle of the electric - control screw lifting module 7.

[0039] To cooperate with the driving and lifting, the electric control screw lifting module 7 is composed of a power motor 71 fixed inside the rotating adjustment seat 62, a driving head 72 installed on the driving shaft of the power motor 71, and a blade 73 movably installed outside the driving head 72.

[0040] The power motor 71 drives the driving head 72 to rotate, and then drives the blade 73 outside the driving head 72 to rotate. Then the blade 73 can be flipped and stored, and the principle is the same as that of the blades of drones on the market.

[0041] The rotating adjustment seat 62 is flipped by the end adjustment motor 61 to perform lateral translation on both sides, and the forward or backward movement is performed by the rotational speed difference between the power motors 71 at both ends.

[0042] To cooperate with the interconnection, arc-shaped adjustment sliding grooves 12 that cooperate with each other are provided on the lower surface of the horizontal base 1, the inner arc surface of the arc-shaped first cover 21, and the inner arc surface of the arc-shaped second cover 22.

[0043] The arc-shaped adjustment sliding groove of the horizontal base 1, the arc-shaped adjustment sliding groove of the arc-shaped first cover 21, and the arc-shaped adjustment sliding groove of the arc-shaped second cover 22 are connected in series with each other when closed to form a circular sliding groove, facilitating the circular sliding of the embedded sliding seat 8 inside it.

[0044] To cooperate with the rotation control, mutually cooperating electromagnets 13 are fixedly assembled on the inner side surface of the arc-shaped adjustment sliding groove 12, and embedded permanent magnets 14 that cooperate with the electromagnets 13 are fixedly assembled inside the embedded sliding seat 8.

[0045] The electromagnets 13 and the embedded permanent magnets 14 cooperate with each other, and drive the embedded permanent magnets 14 to move along the inside of the electromagnets 13 through the principle of like poles repelling each other. The principle is similar to that of magnetic levitation drive, but the embedded sliding seat 8 slides inside the interconnected arc-shaped adjustment sliding grooves 12.

[0046] To cooperate with the optical detection, lateral fixed installation grooves for installing the optical detection module 9 are provided on both sides of the embedded sliding seat 8. The optical detection module 9 includes an infrared detection sensor 91 fixed in the lateral fixed installation groove on one side of the embedded sliding seat 8 and a ultraviolet detection sensor 92 fixed in the lateral fixed installation groove on the other side of the embedded sliding seat 8.

[0047] The function of the infrared detection sensor 91 is to detect the temperature of the cable by detecting the infrared rays emitted from the cable surface, so as to detect internal faults; while the function of the ultraviolet detection sensor 92 is that after ultraviolet rays irradiate on the object surface, they will be reflected or scattered due to defects or cracks in the object, forming some bright spots or dark spots. Different materials show different bright and dark degrees, so that the presence of defects or cracks on the object surface can be judged by analyzing the bright and dark degrees of these reflections or scatterings. Early warning of discharge defects is carried out based on the temperature and the degree of damage to the surface insulation.

[0048] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
