[0040] Example 1

[0041] Referring to Figures 1-4, the first embodiment of the present invention provides an overhead line detection device. This device includes a detection component 100, comprising a mounting component 101, a moving component 102, a detection component 103, and a triggering component 104. The moving component 102, the detection component 103, and the triggering component 104 are disposed on the mounting component 101. The moving component 102, the detection component 103, and the triggering component 104 all act on the mounting component 101. Through the interaction between the mounting component 101, the moving component 102, the detection component 103, and the triggering component 104, the entire device can be installed on the overhead line, and the overhead line can be inspected while in motion.

[0042] Specifically, the mounting component 101 includes an upper mounting cover 101a, a lower mounting cover 101b, a movable plate 101c, and bolts 101d. The upper mounting cover 101a and the lower mounting cover 101b are mounted on the overhead line. Both the upper mounting cover 101a and the lower mounting cover 101b are rectangular with a semi-circular through hole in the center. The upper mounting cover 101a and the lower mounting cover 101b together form a complete unit that can be installed on the overhead line. The movable plate 101c is mounted on the upper mounting cover 101a and is movably connected to the upper mounting cover 101a. On a, there are two movable plates 101c, which are respectively set on both sides of the center position of the upper mounting cover 101a, and there is a certain distance between the two movable plates 101c. There is a through hole on the movable plate 101c, which can correspond to the through hole on the lower mounting cover 101b. The bolt 101d is set on the movable plate 101c and is fixedly connected to the through hole on the movable plate 101c and the lower mounting cover 101b. The upper mounting cover 101a and the lower mounting cover 101b can be installed on the overhead line by means of the bolt 101d.

[0043] Furthermore, the moving component 102 includes a motor 102a, a drive shaft 102b, and a roller 102c. The motor 102a is mounted on the upper mounting cover 101a and is fixedly connected to the upper mounting cover 101a. The motor 102a is positioned near the top of the upper mounting cover 101a. The drive shaft 102b is mounted on the motor 102a and is rotated by the motor 102a. The roller 102c is mounted on the drive shaft 102b and is fixedly connected to the drive shaft 102b. The rotation of the drive shaft 102b will drive the rotation of the roller 102c, allowing the entire device to move on the overhead line. The entire moving component 102 is also mounted on the lower mounting cover 101b. In this way, the device can be controlled to move both above and below the overhead line, allowing the entire device to move on the overhead line upon startup and to move in the opposite direction upon reverse drive.

[0044] Furthermore, the detection component 103 includes an upper moving groove 103a, an upper moving block 103b, a lower moving groove 103c, a control spring 103d, and a lower moving block 103e. The upper moving groove 103a is disposed on the upper mounting cover 101a. The upper moving groove 103a is formed on the upper mounting cover 101a. There are three upper moving grooves 103a. The upper moving grooves 103a are formed from the semi-circular through holes in the upper mounting cover 101a and have a semi-circular structure, extending to the upper mounting cover 101a respectively. At the upper center of position 01a, an upper movable block 103b is positioned on the upper movable groove 103a. The upper movable block 103b is movably connected within the upper movable groove 103a. The upper movable block 103b is a "T" structure rotated 180 degrees, where the "one" part matches the curvature of the overhead line. This structure is designed to contact the overhead line, allowing all three upper movable blocks 103b to contact half of the overhead line. Thus, the upper movable blocks 103b can move within the upper movable groove 103a. The upper moving block 103b can be moved to change position in the upper moving slot 103a according to the overhead line. The lower moving slot 103c is set on the lower mounting cover 101b. The lower moving slot 103c and the upper moving slot 103a have the same number of structures. The control spring 103d is set on the lower moving slot 103c. One side of the control spring 103d is fixedly connected to the lower moving slot 103c. The lower moving block 103e is set on the control spring 103d and is fixedly connected to the lower moving slot 103c. On the other side of the control spring 103d, the lower moving block 103e is connected to the control spring 103d and moves within the lower moving groove 103c. Depending on whether the overhead line is intact, the lower moving block 103e may further squeeze or release the control spring 103d to adjust its position in the lower moving groove 103c. The upper moving block 103b and the lower moving block 103e can be in complete contact with the surface of the overhead line. With the addition of the moving part 102, the entire device can move on the overhead line.

[0045] Furthermore, the actuating element 104 includes a follower groove 104a, a follower rod 104b, a sensor 104c, an upper contact 104d, and a lower contact 104e. The follower groove 104a is disposed on the upper mounting cover 101a, and is formed on one side of the upper moving groove 103a and the lower moving groove 103c. The follower groove 104a is less deep than the upper moving groove 103a, and follows the movement of the sensor. The slot 104a is located in the middle of the upper moving slot 103a, near the side. The number of follower slots 104a is the sum of the upper moving slots 103a and the lower moving slots 103c. The follower rod 104b is disposed on the follower slot 104a and moves on the follower slot 104a. The follower rod 104b is fixedly connected to each upper moving block 103b and lower moving block 103e. The movement of the upper moving block 103b or the lower moving block 103e is... The actuator 104b moves within the actuator groove 104a. Sensor 104c is mounted on the upper mounting cover 101a and is fixedly connected to both the upper and lower mounting covers 101b. Sensor 104c is located on one side of the actuator groove 104a. Sensor 104c can transmit data to the control center. Upper contacts 104d and lower contacts 104e are mounted on sensor 104c. Point 104e is fixedly connected to the upper and lower sides of sensor 104c respectively, and the upper contact 104d and the lower contact 104e are in the follower groove 104a. This allows the movement of follower rod 104b to touch the upper contact 104d or the lower contact 104e to trigger sensor 104c, so that the control center receives an alarm. The distance between the upper contact 104d and the lower contact 104e depends on the depth of the overhead line damage, which will affect the use of the overhead line.

[0046] During the operation, the upper mounting cover 101a and the lower mounting cover 101b are connected vertically on the overhead line. Then, the moving plate 101c is pulled and the bolts 101d are used to install the upper mounting cover 101a and the lower mounting cover 101b on the overhead line, so as to facilitate the next step of the operation.

[0047] The motor 102a that starts the upper mounting cover 101a and the lower mounting cover 101b causes the roller 102c to rotate, and the upper moving block 103b and the lower moving block 103e can move to the surrounding surface of the overhead line, so that the rotation of the roller 102c can drive the device to move on the overhead line.

[0048] The upper moving block 103b and the lower moving block 103e drive the follower rod 104b to move within the follower groove 104a, which can touch the upper contact 104d or the lower contact 104e of the sensor 104c to provide alarm reminders for different situations of the overhead line.

[0049] Example 2

[0050] Referring to Figures 1-8, this is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the device includes a control component 200, including a limiting member 201 and a pulling member 202. The limiting member 201 is disposed on the mounting member 101 and acts on the mounting member 101. The pulling member 202 is disposed on the mounting member 101 and the limiting member 201 and acts on the mounting member 101 and the limiting member 201. This allows the control component 200 to release the movement control of the upper moving block 103b and the lower moving block 103e when the installation device is on an overhead line, preventing the upper moving block 103b and the lower moving block 103e from moving arbitrarily.

[0051] Specifically, the limiting component 201 includes a rotating groove 201a, a limiting groove 201b, a rotating plate 201c, and a control post 201d. The rotating groove 201a is disposed on the upper mounting cover 101a, and is located on one side of the upper moving post. The rotating groove 201a is an arc-shaped groove, which creates an arc-shaped groove on the upper mounting cover 101a near the upper moving block 103b, facilitating the movement of objects on it. The limiting groove 201b is disposed on the upper moving block 103b, and is located on one side of the upper moving block 103b, creating a notch on one side of the upper moving block 103b. An opening facilitates the entry of objects and restricts their position. A rotating plate 201c is set on a rotating groove 201a and is movably connected to the rotating groove 201a. The rotating plate 201c is an arc plate and can move in the rotating groove 201a when subjected to tension or thrust. A control column 201d is set on the rotating plate 201c and is fixedly connected to the rotating plate 201c. The number of control columns 201d is the same as that of the upper moving block 103b. The initial position control column 201d is in the restriction groove 201b of the upper moving block 103b. This ensures that the upper moving block 103b will not move arbitrarily when it is not installed on the overhead line along with the upper mounting cover 101a.

[0052] The upper mounting cover 101a has two limiting members 201, which are respectively located on both sides of the center of the upper mounting cover 101a. The two limiting members 201 are arranged opposite each other, but their positions are not horizontal. They are arranged in an alternating manner on the front and rear sides of the center of the mounting cover. This results in a notch on both sides of the upper moving block 103b, and the control posts 201d on both sides of the upper moving block 103b can move relative to each other or in opposite directions. This means that after the control posts 201d are moved, the control posts 201d on the front and rear limiting members 201 are located on both sides of the upper moving block 103b. This makes the initial restraint of the upper moving block 103b more stable.

[0053] Furthermore, the pulling component 202 includes a pulling groove 202a, a connecting shaft 202b, a pulling block 202c, a pulling rod 202d, and a following groove 202e. The pulling groove 202a is disposed on the upper mounting cover 101a and is a fan-shaped structure, its position corresponding to the rotating plate 201c. The pulling groove 202a provides an opening at the upper mounting cover 101a, facilitating the movement of the object connected to the rotating plate 201c within the pulling groove 202a. The connecting shaft 202b is disposed on the pulling groove 202a and is fixedly connected to the rotating plate 201c. The connecting shaft 202b is a "T"-shaped structure, which increases the contact area of ​​the connecting shaft 202b. The pulling block 202c is disposed on the connecting shaft 202b. 202c and connecting shaft 202b are movably connected. Connecting shaft 202b can move within a groove provided in pulling block 202c. Pulling rod 202d is set on pulling block 202c. One side of pulling rod 202d is connected to pulling block 202c, and the other side is connected to moving plate 101c. The movement of moving plate 101c can drive pulling rod 202d to move together. The movement of pulling rod 202d drives the movement of pulling block 202c, which in turn causes rotating plate 201c on connecting shaft 202b to move. Following groove 202e is set on pulling groove 202a. Following groove 202e is opened on both side walls of pulling groove 202a, that is, on upper mounting cover 101a. Following groove 202e is an arc structure. Due to the arc shape of rotating plate 201c, the arc structure of following groove 202e also facilitates the movement of rotating plate 201c.

[0054] There are two pullers 202 and two restrainers 201 on the upper mounting cover 101a, and their positions are the same as those of the restrainers 201. By pulling the two movable plates 101c of the upper mounting cover 101a, the two pull rods 202d can drive the rotating plates 201c to move in different directions. This also causes the control columns 201d on the two rotating plates 201c to move in different directions, thus removing the restriction on the position of the upper moving block 103b. This allows the upper moving block 103b to move in position as there are missing objects or foreign objects on the overhead line.

[0055] The remaining structure is the same as that in Example 1.

[0056] Operation process: During the installation of the upper cover 101a, the movable plate 101c needs to be pulled. This process will cause the movable plate 101c to drive the pull rod 202d to move in the following groove 202e along with the pull block 202c. This will also cause the connecting shaft 202b and the connected rotating plate 201c in the rotating groove 201a to move. This will further cause the control column 201d to disengage from the limiting groove 201b, releasing the restriction on the movement of the upper movable block 103b. With the help of the trigger 104, the upper movable block 103b and the lower movable block 103e can move up and down according to the situation on the overhead line, which will trigger the sensor 104c.

[0057] Example 3

[0058] Referring to Figures 1-11, this is the third embodiment of the present invention. This embodiment differs from the second embodiment in that: the device includes a protective component 300, including a reversing member 301 and a releasing member 302. The reversing member 301 is disposed on the mounting member 101 and acts on the mounting member 101. The releasing member 302 is disposed on the mounting member 101 and acts on the mounting member 101. By the reversing member 301 and the releasing member 302 acting on the mounting member 101, the entire device can perform a certain degree of self-protection and issue an alarm and indicate the location in the event of an overhead line breakage.

[0059] Specifically, the reverse component 301 includes a motion groove 301a, a reverse post 301b, a connecting plate 301c, a reverse groove 301d, a rotating shaft 301e, a chain ball 301f, and a snap-fit ​​groove 301g. The motion groove 301a is disposed on the upper mounting cover 101a. The motion groove 301a is located on the upper mounting cover 101a near the top and is higher than the position of the motor 102a. The motion groove 301a consists of two oblong grooves respectively disposed on both sides of the upper mounting cover 101a. The reverse post 301b is disposed in the motion groove 301a. Above, the reverse column 301b is movably connected in the motion groove 301a. The reverse column 301b is cylindrical. The connecting plate 301c is disposed on the reverse column 301b and is fixedly connected to one side of the two reverse columns 301b. There are two connecting plates 301c, one on each side of the reverse column 301b, so that the movement of the two columns can be synchronized. The reverse groove 301d is disposed on the connecting plate 301c. The reverse groove 301d is formed in the connecting plate 301c, and the reverse groove 301d creates a groove with a certain distance inside the connecting plate 301c, which facilitates the movement of objects in the connecting groove. The device moves within the receiving plate 301c. The rotating shaft 301e is positioned on the reverse groove 301d, rotatably connected to and centered within the reverse groove 301d. A chain ball 301f is fixedly connected to the rotating shaft 301e. One side of the chain ball 301f has a spherical component. When the device falls, as the entire device descends and the chain ball 301f is only connected to the rotating shaft 301e, the side of the chain ball 301f with the spherical component moves upwards, thus causing the rotating shaft 301e to move. The connecting plate 301c causes the reverse column 301b to move within the motion groove 301a. The latching groove 301g is provided on the connecting plate 301c and is corresponding to the moving plate 101c. When the moving plate 101c moves downward, it causes the connecting plate 301c to move downward. Then, during the continuous movement of the moving plate 101c, and when the reverse column 301b on the connecting plate 301c moves to the bottom of the reverse groove 301d, the moving plate 101c will disengage from the latching groove 301g.

[0060] Furthermore, the release component 302 includes an operating groove 302a, a positioning shaft 302b, a rotating plate 302c, a sealing plate 302d, a trigger block 302e, a sensor 302f, a transfer groove 302g, and a mounting plate 302h. The operating groove 302a is disposed on the upper mounting cover 101a and is located between two moving grooves 301a. Items such as parachutes that can protect the device during descent can be placed inside the operating groove 302a. The positioning shaft 302b is disposed on the operating groove 302a and is fixedly connected within it. There are two positioning shafts 302b, one on each side of the operating groove 302a. Plate 302c is mounted on positioning shaft 302b, and rotating plate 302c is rotatably connected to positioning shaft 302b. Rotating plate 302c consists of two parts: a pressing inclined surface and an opening plate. The pressing inclined surface can move into the motion groove 301a and has a certain inclination surface to facilitate the upward movement of the reverse column 301b, which presses the rotating plate 302c to make it rotate. The opening plate is located on the horizontal surface of the operation groove 302a. Rotating plate 302c is V-shaped. When one side is pressed, the other side of rotating plate 302c can rotate under the action of positioning shaft 302b. Sealing plate 302d is mounted on rotating plate 302c and is fixedly connected to rotating plate 302c. The sealing plate 302d consists of a sealing arc surface and a baffle. The sealing arc surface is fixedly connected between the pressing slope of the rotating plate 302c and the opening plate, thereby ensuring that the rotation of the rotating plate 302c maintains a certain integrity and tight contact. The actuating block 302e is disposed on the rotating plate 302c and is fixedly connected to the rotating plate 302c, located on the pressing slope of the rotating plate 302c. The rotation of the rotating plate 302c causes the actuating block 302e to rotate. The sensor 302f is disposed on the upper mounting cover 101a and is fixedly connected to the upper mounting cover 101a. The sensor 302f can emit a signal when the actuating block 302e approaches. The transfer slot 302g is set on the upper mounting cover 101a. The transfer slot 302g is arc-shaped and is designed to allow the touch block 302e and sensor 302f to move and contact. The mounting plate 302h is set on the operation slot 302a and is fixedly connected inside the operation slot 302a. The mounting plate 302h allows the parachute to be mounted on it. When the sealing plate 302d is opened, the parachute can move upward out of the operation slot 302a. Due to the setting of the mounting plate 302h, the entire device can be protected in the parachute, and the probability of the staff finding it and marking the broken part of the overhead line is increased.

[0061] The remaining structure is the same as that in Example 2.

[0062] Operating Procedures: When the entire device moves to the break point of the overhead line and descends, the rapid descent causes the chain ball 301f to move upwards in the opposite direction, driving the reverse column 301b on the connecting plate 301c to move. The movement of the reverse column 301b can squeeze one side of the rotating plate 302c, causing the other side of the rotating plate 302c and the sealing plate 302d to move as well. At this time, the trigger block 302e and the sensor 302f on the rotating plate 302c will come closer and send a signal. This will also cause the parachute connected to the operating slot 302a and the mounting plate 302h to open to protect the device and mark the break point of the overhead line, making it easier for staff to pick it up and reuse it. This solves the problem of overhead line inspection work in complex terrain and harsh environment conditions.

[0063] Example 4

[0064] As a fourth embodiment of the present invention, an overhead line detection method is provided, comprising the following steps:

[0065] S1. Install the detection device onto the overhead line;

[0066] S2. Start the detection device and move it on the overhead line;

[0067] S3. The detection device transmits detection data back to the control center in real time, enabling continuous monitoring of the overhead line condition, timely detection of potential problems and early warning.

[0068] S4. When the control center issues the first type of alarm, it indicates that the overhead line has been damaged.

[0069] When the control center issues the second type of alarm, it indicates that there is a foreign object on the overhead line;

[0070] When the detection device issues a third alarm, it indicates that the overhead line has broken. At this point, the detection device will drop and deploy a parachute for protection.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
