Description

Technical Field

[0001] This invention relates to an overhead power distribution line pole device, and more specifically, to a device for adjusting and restoring the tilt of a pole that has tilted from an upright state during installation. Background Technology

[0002] Utility poles support overhead power lines and are partially buried underground for stability. However, due to various reasons such as ground subsidence, vehicle collisions, and aging, utility poles may tilt. Once a pole begins to tilt, the weight of the pole and power lines can accelerate the tilt, potentially causing the pole to collapse suddenly.

[0003] Therefore, a method was proposed in the past: to install bolts in the underground part of the utility pole that can adjust the tilt of the pole. When the tilt is confirmed, workers insert tools into the ground and turn the bolts to restore the utility pole to its original tilt.

[0004] However, because workers have to get close to the leaning utility poles and visually check the tilt to adjust the bolts one by one, it is not only dangerous, but also reduces the convenience and accuracy of the work. Summary of the Invention

[0005] The purpose of this invention is to provide an overhead power distribution line pole device that can effectively restore the tilt of the pole as it tilts, thereby making the restoration operation safe and improving the convenience and precision of operation.

[0006] The present invention aims to provide an overhead power distribution line pole device, comprising: a pole body, which is rod-shaped, with its lower end buried vertically in the ground and supporting power distribution lines at its upper end; a support frame having a pole receiving portion disposed underground at the lower part of the pole body for receiving the lower part of the pole body; a plurality of tilt adjustment members installed at predetermined intervals along the outer periphery of the lower part of the pole body within the pole receiving portion, having a tilt adjustment surface that tilts radially downward and contacts the lower part, and being configured to slide radially; a drive unit for slidingly driving the plurality of tilt adjustment members; a sensor unit for sensing the tilt value of the pole body; and a control unit for causing at least one corresponding tilt adjustment member among the plurality of tilt adjustment members to slide, so that the tilt of the pole body is within a predetermined reference tilt range, thereby realizing the overhead power distribution line pole device.

[0007] The aforementioned control unit can identify the tilt direction of the utility pole body based on the sensed tilt value, and control the drive unit to move the tilt adjustment member on the identified tilt direction side radially inward. This allows the tilt adjustment member on the tilt direction side to move radially inward, thereby efficiently restoring the tilt of the utility pole body.

[0008] The aforementioned tilt adjustment components are configured to rotate around the standing direction. A drive unit rotates and drives the multiple tilt adjustment components, and a control unit controls the drive unit to rotate at least one of the multiple tilt adjustment components, thereby controlling the tilt of the utility pole body to fall within a reference tilt range. Accordingly, by rotating the tilt adjustment components, the tilt of the utility pole body in various directions can be adaptively restored.

[0009] The aforementioned control unit can control the drive unit so that a pair of tilt adjustment members adjacent to the entering tilt adjustment member among the multiple tilt adjustment members rotate in the direction in which the tilt adjustment member enters.

[0010] The aforementioned tilt adjustment component includes a low-slope section along the outer perimeter and a high-slope section with a slope angle greater than that of the low-slope section, positioned to contact the two boundaries of the low-slope section. The control unit can rotate the tilt adjustment component in one direction to prevent the slope of the utility pole body from falling within the reference slope range, and can also rotate the tilt adjustment component in the opposite direction. This allows the tilt of the utility pole body to be quickly restored.

[0011] The invention also includes a vibration unit that causes the tilt adjustment member to vibrate in a predetermined direction. When the tilt angle of the utility pole body is not within a reference tilt angle range, the control unit can control the vibration unit to vibrate the tilt adjustment member by rotating the tilt adjustment member. Thus, vibration can be used to promote the rotation of the tilt adjustment member, thereby enabling a more rapid restoration of the tilt angle of the utility pole body.

[0012] According to the present invention, the tilt of the utility pole can be effectively restored as it tilts, thus providing an overhead power distribution line utility pole device that ensures safe restoration operations and improves operational convenience and precision.

[0028] This disclosure will be described in detail below with reference to the accompanying drawings.

[0029] However, the technical ideas, core configurations, and operations of this disclosure are not limited to the configurations or operations described in the following examples. In describing this disclosure, detailed descriptions of known technologies or configurations related to this disclosure will be omitted if it is determined that such detailed descriptions might unnecessarily obscure the subject matter of this disclosure.

[0030] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. This is to provide a detailed description so that those skilled in the art can readily practice the invention, and the technical concept and scope of the invention are not limited thereto.

[0031] Figure 1 This is a cross-sectional view of an overhead power distribution line pole device 10 with a tilt recovery function using tetrahedrons according to an embodiment of the present invention. Figure 2 By sliding Figure 1 The tilt adjustment component 5 performs the tilt recovery function. Figure 3 Is with execution Figure 2 A cross-sectional view related to the recovery process. It should be noted that... Figures 1 to 3 In the text, only some cutouts are used to indicate the main components.

[0032] Below, we will refer to Figures 1 to 3 First, the structure of the overhead power distribution line pole device 10 with tilt recovery function using tetrahedrons according to an embodiment of the present invention will be described, and the process of thereby restoring tilt will be described.

[0033] The overhead power distribution line pole device 10 of this embodiment is a structure erected on the roadside or elsewhere for power supply, communication, etc., and may include a utility pole, a communication pole, etc. Specifically, it includes a pole body 1, a support frame 3, multiple tilt adjustment components 5, a drive unit 6, a sensor unit 7, and a control unit 8.

[0034] The main body 1 of the utility pole is pole-shaped, with its lower end buried vertically in the ground (b) and its upper end supporting the power distribution line (a). When the main body 1 of the utility pole is buried vertically, its axis (c) can be called the vertical axis (pc). The main body 1 of the utility pole is made of a mixture of reinforced concrete and gravel, but is not limited to these materials.

[0035] The support frame 3 is installed in the ground b below the main body 1 of the utility pole and has an electrode receiving portion 2 configured to accommodate the lower end of the main body 1 of the utility pole. The support frame 3 can be made of a heavy-duty material, which can stably hold the main body 1 of the utility pole in an upright position while accommodating the lower end of the main body 1. As an example, the support frame 3 can be configured as a hexahedron made of metal, concrete, carbon fiber composite material, etc., having the electrode receiving portion 2, but is not limited to this, and can be configured in various shapes.

[0036] The upper surface of the support frame 3 includes an inlet into which the lower end of the pole body 1 can be inserted. Most of the lower and side surfaces of the support frame 3, except for the inlet on the upper surface, are buried in the ground. The inlet may have a shape corresponding to the outer periphery of the lower part of the pole body 1, allowing for smooth insertion of the lower part of the pole body 1. When the lower end of the pole body 1 is inserted into the electrode receiving part 2 through the inlet, the support frame 3 supports the lower part of the pole body 1, enabling the pole body 1 to remain stably upright.

[0037] A support frame 3 may be formed at the insertion point at the lower end of the pole body 1, and may include a contact support portion 9 that contacts and supports the outer peripheral surface of the pole body 1. At the insertion point of the support frame 3, as the inclination angle d1 of the pole body 1 changes, the outer peripheral surface of the pole body 1 rises and falls relative to the support frame 3, which generates friction between the outer peripheral surface of the pole body 1 and the contact support portion 9. The contact support portion 9 may include a friction-reducing portion, such as a rolling bearing or a ball bearing, to minimize friction with the outer peripheral surface of the pole body 1.

[0038] According to various embodiments, foreign objects may flow into the electrode receiving part 2 through the gap between the outer peripheral surface of the pole body 1 and the contact support part 9. To prevent this, the overhead power distribution pole device 10 may also include a foreign object prevention cover 11. As an example, one side of the foreign object prevention cover 11 may be arranged to surround the outer peripheral surface of the pole body 1, and even if the inclination d1 of the pole body 1 changes, one side of the foreign object prevention cover 11 may be flexible to maintain the connection with the outer peripheral surface of the pole body 1. For this purpose, the foreign object prevention cover 11 may be made of silicone rubber, EPDM (ethylene propylene diene monomer) rubber, TPU (thermoplastic polyurethane), etc. Silicone rubber, EPDM, TPU, etc. have excellent flexibility, and can maintain the gap seal between the outer peripheral surface of the pole body 1 and the contact support part 9 even if the outer peripheral surface of the pole body 1 is raised or lowered relative to the support frame 3.

[0039] Multiple tilt adjustment members 5 are installed inside the pole receiving part 2 and spaced apart at predetermined intervals along the outer periphery of the lower end of the pole body 1. In the following description, for ease of explanation, it is assumed that the first to fourth tilt adjustment members 31, 32, 33, and 34 are equally spaced along the outer periphery of the lower end of the pole body 1. However, the number and arrangement of the tilt adjustment members 5 can be varied according to different design methods.

[0040] The tilt adjustment member 5 is a tetrahedron tilted radially downwards and has a tilt control surface 4 that contacts the lower end of the pole body 1. For ease of explanation, when the lower part of the pole body 1 is buried vertically in the ground (b), the first point p1 of the lower part of the pole body 1 contacts the first tilt control surface 41 of the first tilt adjustment member 31, and the second point p2 contacts the second tilt control surface 42 of the second tilt adjustment member 32. Alternatively, the lower end of the pole body 1 may also contact the third tilt control surface 43 of the third tilt control element 33 or the fourth tilt control surface 44 of the fourth tilt control element 34.

[0041] Since the first point p1 and the second point p2 are horizontal when the main body 1 of the utility pole is upright, the vertical distances of the first point p1 and the second point p2 from the bottom surface of the support frame 3 can be the same.

[0042] The tilt adjustment member 5 is configured to slide radially. The tilt adjustment member 5 can be configured as a wedge shape that can move between the lower end of the pole body 1 and the lower surface of the support frame 3. Since the tilt adjustment member 5 slides radially while in contact with the lower end of the pole body 1, it can be made of a material capable of withstanding friction with the lower end of the pole body 1. For example, the tilt adjustment member 5 can be made of high-strength steel with high compressive strength and durability, aluminum alloy that is lighter than steel and has better corrosion resistance, and carbon fiber composite material with a high compressive strength-to-weight ratio, but is not limited to these.

[0043] The lower end of the utility pole body 1 may be covered with a friction-reducing cover member 14 to reduce friction with the tilt control surface 4. The friction-reducing cover member 14 may have a shape that allows the first point p1 and the second point p2 to make surface contact with the first tilt control surface 41 and the second tilt control surface 42. The frictional force at the first point p1 and the second point p2 can be reduced by the friction-reducing cover member 14.

[0044] The tilt adjustment component 5 may also include wheels, rolling bearings, ball bearings, etc., which can run on the lower surface of the support frame 3 to allow the utility pole body 1 to slide smoothly. For example, when a track is installed on the lower surface of the support frame 3, the tilt adjustment component 5 can roll on the track and slide stably on the lower surface of the support frame 3.

[0045] The drive unit 6 causes multiple tilt adjustment members 5 to slide. For example, when a first point p1 at the bottom of the pole body 1 contacts the first tilt control surface 41 of the first tilt adjustment member 31, the drive unit 6 allows the first point p1 at the bottom of the pole body 1 to rise on the first tilt control surface 41 as the first tilt adjustment member 31 moves radially inward. Sufficient driving force can be provided to the first tilt adjustment member 31. For this purpose, the drive unit 6 may include a high-output motor, a hydraulic actuator, a hydraulic cylinder, etc. When the drive unit 6 is implemented as a cylinder, the tilt adjustment member 5 is connected to the drive unit 6 via a piston rod and can slide forward or backward in the radial direction while reciprocating piston motion occurs within the cylinder.

[0046] Sensor unit 7 senses the tilt angle of the utility pole body 1. As an example, sensor unit 7 is a tilt meter that measures gravitational acceleration and calculates the tilt angle, and may include a MEMS (microelectromechanical systems) tilt meter, an electrolyte tilt meter, a capacitive tilt meter, etc. Figure 1 In the figures, sensor unit 7 is shown as being mounted on support frame 3, but sensor unit 7 is not limited thereto, and sensor unit 7 may be mounted on pole body 1.

[0047] The control unit 8 consists of a processor, CPU, chip, etc., and controls the drive unit 6 so that the tilt of the pole body 1 is within a predetermined reference tilt range d0 based on the tilt value sensed by the sensor unit 7, so that at least one of the multiple tilt adjustment members 5 slides.

[0048] For example, when the utility pole body 1 is upright, due to ground subsidence, vehicle collisions, aging, etc., the axis c of the utility pole body 1 may tilt relative to the upright axis pc at an angle d1. Assume this angle d1 is outside the reference tilt angle range d0. The reference tilt range d0 is a safe tilt range based on safety standards, laws, etc., and may be, for example, within 3 degrees based on the upright axis pc of the utility pole body 1, but is not limited to this. The control unit 8 can identify that the tilt angle d1 of the utility pole body 1 is outside the reference tilt angle range d0 by using the tilt angle value from the sensor unit 7.

[0049] More specifically, the control unit 8 uses the sensor unit 7 to measure the current tilt d1 of the pole body 1. The sensor unit 7 measures the tilt value (d1x). The control unit 8 can calculate the slope d1 of the vector by substituting the provided slope value (d1x, d1y) into the following formula (1).

[0050] .............................Formula (1) The control unit 8 calculates the difference between the slope d1 of the main body 1 and the standard slope range d0, thereby calculating the slope change Δd. The slope change Δd can be calculated using the following formula (2).

[0051] △d=d1-d0................................Formula (2) If the slope change Δd > 0, the control unit 8 determines that the slope d1 of the main body 1 of the utility pole exceeds the reference slope range d0, and performs a recovery operation to bring the slope d1 of the main body 1 of the utility pole back into the reference slope range d0. Conversely, if the slope change Δd < 0, the control unit 8 determines that the slope d1 of the main body 1 is within the reference slope range d0, and does not perform a recovery operation.

[0052] The control unit 8 can control the drive unit 6 to move the first tilt adjustment member 31 radially inward to restore the tilt d1 of the utility pole body 1. As the first tilt adjustment member 31 moves radially inward, the first point p1 at the bottom of the body 1 rises along the first tilt control surface 41, and the side of the body 1 corresponding to the first point p1 can rise more than the side corresponding to the second point p2, thereby gradually restoring the tilt d1 of the utility pole body 1.

[0053] When performing the recovery operation, the control unit 8 calculates the recovery tilt angle d1 of the main body 1 based on the slope value sensed by the sensor unit 7. If the slope change Δd < 0, it is determined that the slope d1 of the main body 1 is within the reference slope range d0, and the recovery operation can be stopped. On the other hand, if the slope change Δd > 0, it is determined that the slope d1 of the main body 1 has not yet entered the reference slope range d0, and the repair operation can continue until the slope d1 of the main body 1 enters the reference slope range d0.

[0054] The overhead power distribution line pole device 10 can be used not only in this repair process, but also when the lower part of the pole body 1 is initially buried in the ground b. For example, in order to enable the power distribution line body 1 to be installed in an upright position, the overhead power distribution line pole device 10 can keep the inclination d1 of the body 1 within the standard inclination range d0.

[0055] Thus, when the overhead power distribution line pole device 10 of this embodiment is used, unlike the related technology in which workers approach the pole body and manually use tools to restore the tilt according to the tilt of the pole body, the tilt d1 can be effectively restored as the pole body 1 tilts, which not only restores work safety, but also improves the convenience and accuracy of the work.

[0056] Of course, manual restoration work is also possible using the overhead power distribution line pole device 10 of this embodiment. For example, the overhead power distribution line pole device 10 may also include an insert 12 that can enter between the first tilt adjustment member 31 and the side of the support frame 3, and a pressure rod 13 for pressurizing the insert 12. The insert 12 may be wedge-shaped. The pressure rod 13 may extend towards the ground and penetrate the main receiving section 2, with a portion of it exposed towards the ground. When the worker manipulates the exposed portion of the pressure rod 13 from the ground side to pressurize the insert 12, the insert 12 can be pushed between the first tilt adjustment member 31 and the side of the support frame 3, thereby causing the first tilt adjustment member 31 to slide radially.

[0057] Therefore, the tilt angle d1 of the main body 1 can be manually restored to the standard tilt range d0.

[0058] According to various embodiments, the control unit 8 can determine the recovery angle dc required for tilt recovery. The recovery angle dc can represent the minimum angle between the axis c of the main body 1 and the vertical axis pc, which makes the tilt d1 of the main body 1 fall within the standard tilt range d0. When the control unit 8 performs a recovery operation due to the slope change Δd>0, the recovery angle dc can be calculated by taking into account the slope change Δd, the height H of the main body 1, the diameter D, the elastic coefficient k, etc., using the following formula (3).

[0059] dc=△d / (1+(h / D)·k)........................................Formula (3) Here, the required vertical displacement (h) of the lower part can include the vertical distance (hp1, hp2) required from the bottom surface of the support frame 3 of the main body 1 to the first point p1 and the second point p2, so that the tilt angle d1 falls within the reference slope range d0. If the required vertical displacement h of the lower part is expressed as the required vertical distance (hp1, hp2) at the first point p1 and the second point p2, then the formula (3) can be dc=△d / (1+(hp1-hp2 / 2D)·k).

[0060] The control unit 8 can calculate the entry distance e31 of the first tilt adjustment member 31 based on the determined recovery angle dc. The entry distance e31 of the first tilt adjustment member 31 corresponding to the recovery angle (dc) can be calculated by formula (4).

[0061] e31=(2H·tan(dc)) / tan(θ)................................Formula (4) Here, θ can represent the angle of the first tilt control surface 41 of the first tilt adjustment member 31. The control unit 8 can restore the tilt d1 of the main body 1 to the standard tilt range d0 by sliding the first tilt adjustment member 31 along the calculated entry distance e31.

[0062] In this way, by sliding the tilt adjustment member 5 with the entry distance e31 calculated based on the recovery angle dc of the main body 1, the tilt d1 of the utility pole main body 1 can be effectively restored.

[0063] According to various embodiments, the control unit 8 can control the drive unit 6 to move the opposing second tilt adjustment member 32 radially outward, while the first tilt adjustment member 31 moves radially inward. When the second tilt adjustment member 32 retracts, and the side corresponding to the first point p1 rises due to the entry of the first tilt adjustment member 31, the second point p2 at the lower part of the main body 1 descends along the second tilt adjustment surface 42, thereby enabling the side corresponding to the second point p2 to descend.

[0064] Therefore, compared with the case of using only one tilt adjustment member 5, the tilt d1 of the utility pole body 1 can be restored more quickly.

[0065] According to various embodiments, the control unit 8 can calculate the approach distance e31 of the first tilt adjustment member 31 and the retraction distance of the second tilt adjustment member 32 based on the recovery angle dc. By sliding the first tilt adjustment member 31 and the second tilt adjustment member 32 by the amount of the approach and retraction distances calculated based on the recovery angle dc, the control unit 8 can more effectively and quickly restore the tilt d1 of the utility pole body 1.

[0066] According to various embodiments, in order to stably restore the slope, a time difference can be set between the entry of the first slope adjustment member 31 and the retraction of the second slope adjustment member 32. For example, if the second tilt adjustment member 32 advances backward a calculated distance under the control of the control unit 8, the second point p2 of the main body 1 can be lowered. As the second point p2 of the main body 1 descends, the tilt d1 of the main body 1 can be partially restored.

[0067] Furthermore, when the first tilt adjustment member 31 moves backward into the calculated entry distance after the movement of the main body 1 has stabilized for a period of time due to the decrease of the second point p2, the tilt d1 of the main body 1 can be largely restored as the first point p1 of the main body 1 rises.

[0068] In this way, by setting the time difference between the sliding of multiple tilt adjustment components 5, the tilt d1 of the utility pole body 1 can be restored more stably.

[0069] According to various embodiments, the control unit 8 can restore the tilt angle d1 of the utility pole body 1 by moving both the first tilt adjustment member 31 and the second tilt adjustment member 32 radially inward. This is due to the structural characteristics of the utility pole receiving unit 2. If the entry distance e31 of the first tilt adjustment member 31 is greater than the entry distance of the second tilt adjustment member 32, then the rise of the side corresponding to the first point p1 caused by the entry of the first tilt adjustment member 31 can be greater than the rise of the side corresponding to the second point p2 caused by the entry of the second tilt adjustment member 32. Therefore, the tilt angle d1 of the utility pole body 1 can be restored to the reference tilt range d0.

[0070] According to various embodiments, the control unit 8 identifies the tilt direction of the body 1 based on the sensed tilt value, and controls the drive unit 6 to move the tilt adjustment member 5 in the identified tilt direction radially inward.

[0071] For example, if the control unit 8 determines that the tilt angle d1 of the utility pole body 1 needs to be restored, the control unit 8 can identify the tilt direction of the body 1 based on the tilt value sensed by the sensor unit 7. For ease of explanation, assume that the body 1 is tilted along the direction of the first tilt adjustment member 31. The control unit 8 can identify, based on the position information of the multiple tilt adjustment members 5, that the first tilt adjustment member 31 exists at the position corresponding to the identified tilt direction among the multiple tilt adjustment members 5, and control the drive unit 6 to move the first tilt adjustment member 31 radially inward.

[0072] Accordingly, by preferentially driving the tilt adjustment member 5 at the position corresponding to the tilt direction among the multiple tilt adjustment members 5, the tilt d1 of the utility pole body 1 can be effectively restored.

[0073] According to different embodiments, the main body 1 can tilt between a pair of tilt adjustment members 5. For ease of explanation, it is assumed that the main body 1 tilts between the first tilt adjustment member 31 and the third tilt adjustment member 33. In this case, the control unit 8 can identify that the tilt direction of the main body 1 is between the first tilt adjustment member 31 and the third tilt adjustment member 33. As described above, the control unit 8 can calculate the recovery angle dc of the main body 1, and determine the entry distance e31 of the first tilt adjustment member 31 and the entry distance or retraction distance of the third tilt adjustment member 33 based on the recovery angle dc. The entry and retraction distances of the first tilt adjustment member 31 and the third tilt adjustment member 33 can vary according to the tilt direction of the main body 1, the amount of tilt change Δd, etc., and can be calculated in various ways. If the tilt direction is closer to the first tilt adjustment member 31, the entry distance e31 of the first tilt adjustment member 31 can be calculated to be greater than the entry distance of the third tilt adjustment member 33.

[0074] Based on this, the tilt d1 of the main body 1 of the utility pole in each direction can be adaptively restored.

[0075] Figure 4 Through sliding and rotating Figure 1 A cross-sectional view of the process by which the tilt adjustment component 5 performs the tilt recovery function.

[0076] like Figure 4 As shown, a plurality of tilt adjustment members 5 are provided, which can rotate around the standing direction on the ground. The drive unit 6 drives the plurality of tilt adjustment members 5 to rotate. The control unit 8 controls the drive unit 6 to rotate at least one of the plurality of tilt adjustment members 5, so that the tilt angle d1 of the main body 1 falls within the standard tilt range d0.

[0077] For example, when the main body 1 tilts towards the first tilt adjustment member 31 at an angle d1, the control unit 8 can control the drive unit 6 to rotate the third tilt adjustment member 33 counterclockwise by r1, causing one side of the third tilt adjustment member 33 to move radially inward. Furthermore, the control unit 8 can control the drive unit 6 to rotate the fourth tilt adjustment member 34 clockwise by r2, causing one side of the fourth tilt adjustment member 34 to move radially inward. Considering the radius of rotation R of the third tilt adjustment member 33 or the fourth tilt adjustment member 34, the rotation angle of the third tilt adjustment member 33 or the fourth tilt adjustment member 34 can be calculated using formulas such as [sin⁻¹(H·tan(dc)) / R].

[0078] At the third and fourth points where the third tilt adjustment surface 43 of the third tilt adjustment member 33 and the fourth tilt adjustment surface 44 of the fourth tilt adjustment member 34 come into contact at the lower part of the main body 1, as they rise along the third tilt adjustment surface 43 and the fourth tilt adjustment surface 44, the side corresponding to the first point p1 on both sides of the main body 1 that is adjacent to the third and fourth points can rise higher than the side corresponding to the second point p2, thereby gradually restoring the tilt angle d1 to within the reference slope range d0.

[0079] Specifically, by adjusting the rotation angles of the third tilt adjustment member 33 and the fourth tilt adjustment member 34, the tilt angle d1 can be restored to the reference tilt range d0 not only when the main body 1 tilts towards the first tilt adjustment member 31 with a tilt angle d1, but also, for example, when the main body 1 tilts between the first tilt adjustment member 31 and the third tilt adjustment member 33.

[0080] Accordingly, by rotating the tilt adjustment component 5, the tilt d1 of the utility pole body 1 in each direction can be adaptively restored.

[0081] According to various embodiments, the control unit 8 controls the drive unit 6 such that a pair of tilt adjustment members 5 adjacent to the entering tilt adjustment member 5 among the plurality of tilt adjustment members 5 rotate along the entering direction of the tilt adjustment member 5.

[0082] For example, when the main body 1 tilts towards the first slope adjustment member 31 at an angle d1, the drive unit 6 can be controlled to restore the angle d1 to within the reference slope range d0, so that the first slope adjustment member 31 moves radially inward. At the same time, the drive unit 6 can be controlled to rotate the third slope adjustment member 33 counterclockwise, so that one side of the third slope adjustment member 33 moves radially inward. The fourth slope adjustment member 34 can be rotated clockwise, so that one side of the fourth slope adjustment member 34 moves radially inward.

[0083] Therefore, by balancing the restoring force generated by sliding and the restoring force generated by rotation, the tilt d1 of the main body 1 of the utility pole can be quickly restored.

[0084] Figure 5 By rotating Figure 1 A cross-sectional view of the process by which the tilt adjustment component 5 performs the angle restoration function.

[0085] The sensor unit 7 senses the torsion angle of the main body 1 based on axis c, and the control unit 8 can control the drive unit 6 to rotate at least one of the multiple tilt adjustment members 5 in the direction of reducing the torsion angle of the main body 1.

[0086] For example, when a vehicle collides with the main body 1, the main body 1 will not tilt, but will rotate around axis c by a first torsion angle e1. In this case, the sensor unit 7 can measure the first torsion angle e1. For this purpose, the sensor unit 7 may include a torque sensor, an encoder, a strain gauge, etc.

[0087] The control unit 8 can control the drive unit 6 to rotate at least one of the first to fourth tilt adjustment members 31, 32, 33, and 34 in the direction that the first torsion angle e1 decreases. For example, the rotation can be resumed to return to the first torsion angle e1, or the first torsion angle e1 can be controlled to fall within a reference torsion angle range. The standard torsion angle range may be a safe torsion angle range specified according to safety standards, laws, etc., but is not limited thereto.

[0088] Therefore, even if the angle is distorted due to the rotation of the main body 1, it can be restored.

[0089] Figure 6 This is a cross-sectional view of an overhead power distribution line pole device 20 with asymmetric rotation tilt recovery function according to another embodiment of the present invention. Figure 7 It shows the way Figure 6 An example of using the rotation of the tilt adjustment member 51 to perform the tilt recovery function. Figure 8 To and Figure 7 A cross-sectional view related to an example of performing tilt recovery functionality. It is worth noting that... Figures 6 to 8 Only the main components are partially cut out and represented.

[0090] The following will refer to Figures 6 to 8 First, the structure of an overhead power distribution line pole device 20 with asymmetric rotation tilt recovery function according to another embodiment of the present invention is described, and the process of these devices restoring tilt is described. However, for ease of explanation, references will be omitted. Figure 1 The description of the structure of the overhead power distribution line pole device 10 overlaps with the description of the structure, while the description of the different parts is concentrated.

[0091] The overhead power distribution line pole device 20 of this embodiment includes a pole body 1, a support frame 3, multiple tilt adjustment components 51, a drive unit 53, a sensor unit 7, and a control unit 8.

[0092] Figure 1 The pole body 1, support frame 3, and sensor section 7 of the overhead power distribution line pole device 10 can be used as the pole body 1, support frame 3, and sensor section 7 of the overhead power distribution line pole device 20 in this embodiment.

[0093] The tilt adjustment member 51 is disc-shaped and is disposed inside the column receiving part 2 and contacts the lower end of the utility pole body 1. It has a tilt adjustment surface 52, which gradually changes the tilt angle radially downward along the outer periphery of the lower end, so that it can rotate around the axis c.

[0094] The tilt adjustment member 51 has the following characteristics: Figure 6 The shape shown is provided, and it has a tilt adjustment surface 52 with a tilt angle. However, the shape of the tilt adjustment member 51 and the tilt angle of the tilt adjustment surface 52 can be set in various ways according to the design method.

[0095] For ease of explanation, in the initial upright state where the lower part of the main body 1 is buried in the ground (b), it is assumed that the first point p1 and the second point p2 of the lower part of the main body 1 are in contact with the radially downward inclined control surface 52. Since the first point p1 and the second point p2 are horizontal, the vertical distance from the bottom surface of the support frame 3 to the first point p1 and the second point p2 can be the same. Of course, the lower part of the main body 1 can also be in contact with the slope adjustment surface 52.

[0096] The tilt adjustment member 51 is configured to rotate about axis c. According to the design method, the tilt adjustment member 51 can be configured to rotate about a rotation axis rc that is different from the axis c of the main body 1. When the main body 1 is installed, the axis c of the main body 1 may be eccentric in an upright state and separate from the rotation axis rc.

[0097] The tilt adjustment member 51 can be made of a material that can withstand the frictional force between itself and the lower part of the main body 1 when rotating while in contact with the lower part of the main body 1. For example, the tilt adjustment member 51 can be made of high-strength steel, aluminum alloy, carbon fiber composite material, etc. Of course, a friction-reducing cover 14 can also be placed on the lower part of the main body 1 to reduce friction with the slope adjustment surface 4.

[0098] The tilt adjustment member 51 may also include wheels, rolling bearings, ball bearings, etc., that can rotate on the lower surface of the support frame 3 to ensure smooth rotation about the rotation axis rc. For example, the tilt adjustment member 51 can rotate stably along a track installed on the lower surface of the support frame 3.

[0099] The drive unit 53 rotates the tilt adjustment member 51. For example, the drive unit 53 is disposed between the side of the support frame 3 and the outer surface of the tilt adjustment member 51 to transmit driving force to the outer surface of the tilt adjustment member 51. For this purpose, the drive unit 6 may include a high-power motor, a hydraulic actuator, a gearbox, etc. When the drive unit 6 uses a gearbox, the tilt adjustment member 51 can rotate by meshing with a gear formed on the outer surface of the tilt adjustment member 51.

[0100] When the first point p1 and the second point p2 at the lower part of the main body 1 come into contact with the tilt adjustment surface 52, the drive unit 53 can rotate the tilt adjustment member 51 and provide sufficient driving force so that the first point p1 and the second point p2 at the lower part of the main body 1 can rise or fall along the tilt adjustment surface 52.

[0101] The control unit 8 calculates the tilt d1 of the main body 1 by substituting the tilt value sensed by the sensor unit 7 into the formula (1), and controls the drive unit 53 to rotate the tilt adjustment member 51 so that the calculated tilt d1 of the main body 1 is within the predetermined reference tilt range d0.

[0102] For example, suppose that when the first point p1 and the second point p2 at the bottom of the main body 1 come into contact with the tilt adjustment surface 52 of the tilt adjustment member 51, due to ground subsidence or other reasons, the axis c of the main body 1 tilts relative to the vertical axis pc by an angle d1, and the angle d1 is outside the standard tilt range d0. The control unit 8 can identify that the angle d1 of the main body 1 exceeds the standard tilt range d0 by the angle value of the sensor unit 7. For example, the control unit 8 calculates the slope change Δd according to formula (2). If the slope change Δd>0, it is determined that the slope d1 of the pole body 1 exceeds the reference slope range d0, and a recovery operation can be performed to make the slope d1 of the pole body 1 fall into the reference slope range d0.

[0103] The control unit 8 controls the drive unit 53 to rotate the tilt adjustment member 51, restoring the tilt angle d1 of the utility pole body 1 to within the standard tilt range d0. For ease of explanation, assuming the tilt adjustment member 51 rotates counterclockwise, the first point p1 and the second point p2 on the lower part of the body 1 can rise or fall along the slope adjustment surface 52 with a gradually changing slope angle according to the counterclockwise rotation of the tilt adjustment member 51. Since the axis c of the body 1 is eccentric to the rotation axis rc of the tilt adjustment member 51, the side corresponding to the first point p1 of the body 1 can rise, and the side corresponding to the second point p2 can fall, thereby gradually restoring the tilt angle d1 of the utility pole body 1.

[0104] When performing a recovery operation, the control unit 8 calculates the recovery tilt angle d1 of the main body 1. If the change in slope Δd < 0, the recovery operation can be stopped. On the other hand, if the change in slope Δd > 0, the recovery operation can continue until the slope d1 of the main body 1 falls within the reference slope range d0.

[0105] The overhead power distribution line pole device 20 can be used not only in this repair process, but also when the lower part of the pole body 1 is initially buried in the ground b. For example, in order to enable the pole body 1 to be installed in an upright position, the overhead power distribution line pole device 20 can keep the inclination d1 of the body 1 within the standard inclination range d0.

[0106] Thus, when the overhead power distribution line pole device 20 of this embodiment is used, unlike the related technology in which workers approach the pole body and manually use tools to restore the tilt based on the tilt of the pole body, this embodiment can effectively restore the tilt based on the tilt of the pole body 1, which not only restores work safety, but also improves the convenience and accuracy of the work.

[0107] Of course, it is not impossible to manually perform restoration work using the overhead power line pole device 20 of this embodiment. For example, the overhead power line pole device 20 may also include a rotating rod connected to the outer surface of the tilt adjustment member 51. The rotating rod may extend into the ground through the main receiving part 2, with a portion of it exposed towards the ground. When a worker manipulates the exposed portion of the rotating rod from the ground side, the tilt adjustment member 51 can rotate.

[0108] Therefore, the tilt angle d1 of the main body 1 can be manually restored to the standard tilt range d0.

[0109] According to various embodiments, the control unit 8 can use formula (3) to determine the recovery angle dc required for tilt recovery, and calculate the rotation angle rr of the tilt adjustment member 51 based on the determined recovery angle dc. For example, the rotation angle rr of the tilt adjustment member 51 corresponding to the recovery angle dc can be calculated according to formula (5).

[0110] rr=H·tan(dc)(1 / tan(θ1)+1 / tan(θ2)).............Formula (5) Here, θ1 can be the tilt angle of the tilt control surface 52 corresponding to the first point p1, and θ2 can be the tilt angle of the tilt control surface 52 corresponding to the second point p2. For example, the tilt angle θ1 of the tilt control surface 52 corresponding to the first point p1 and the tilt angle θ2 of the tilt control surface 52 corresponding to the second point p2 can be the lowest and highest tilt angles of the tilt control surface 52. The control unit 8 can restore the tilt angle d1 of the main body 1 to the standard tilt range d0 by rotating the tilt adjustment member 51 by the calculated rotation angle rr.

[0111] In this way, by rotating the tilt adjustment member 51 with the rotation angle rr calculated based on the recovery angle dc of the main body 1, the tilt d1 of the utility pole main body 1 can be effectively restored.

[0112] According to various embodiments, the control unit 8 can calculate the torque T of the drive unit 53. For ease of explanation, assuming that the weight of the main body 1 is 500 kg and the tilt angle d1 of the main body 1 is 5 degrees, the drive unit 53 can be controlled to drive with a torque of about 250 Nm, and the torque is calculated by the following formula (6).

[0113] T=W Х H Х sin (d1).................................Formula (6) Here, W can be the weight of the main body. In this way, by calculating the torque T and driving the drive unit 53, the optimal torque T can be used, thus more effectively restoring the tilt d1 of the pole body 1.

[0114] Figure 9 It shows Figure 6 An example of tilt adjustment member 51 rotating in the opposite direction to perform tilt recovery function.

[0115] Below, refer to Figure 8 Describe the process of effectively restoring the tilt d1 of the main body 1 of the utility pole.

[0116] According to this embodiment, the tilt adjustment member 51 includes a low-slope portion 54 arranged along the outer periphery of the main body 1 and a high-slope portion 55 having a higher tilt angle than the low-slope portion 54 and arranged to contact the two boundaries of the low-slope portion 54. The low-slope portion 54 may include the portion of the slope control surface 52 with a tilt angle θ1 corresponding to the first point p1, and the high-slope portion 55 may include the portion of the slope control surface 52 with a tilt angle θ2 corresponding to the second point p2.

[0117] Since the boundary between the low slope section 54 and the high slope section 55 can be seamlessly connected, as the tilt adjustment member 51 rotates, the first point p1 and the second point p2 at the bottom of the main body 1 can naturally cross the boundary between the low slope section 54 and the high slope section 55.

[0118] exist Figure 8 In the diagram, the gentle slope angle of low slope section 54 is drawn longer with thin arrows, while the steep slope angle of high slope section 55 is drawn shorter with thick arrows, thus distinguishing the slope length and slope of low slope section 54 and high slope section 55. Of course, the direction of the arrows indicates the downward direction of low slope section 54 and high slope section 55.

[0119] For ease of explanation, assume that the axis c of the main body 1 in its upright position is eccentrically positioned towards the lower tilt section 54 relative to the rotation axis rc of the tilt adjustment member 51. When the axis c of the main body 1 tilts at an angle d1 relative to the vertical axis pc, the axis c can be moved and positioned towards the higher tilt section 55 relative to the rotation axis rc. If the tilt angle d1 of the main body 1 exceeds the standard tilt range d0, the control unit 8 can perform a recovery operation by rotating the tilt adjustment member 51 in one direction. As the tilt angle d1 of the main body 1 is gradually restored through this recovery operation, the axis c of the main body 1 moves from the higher tilt section 55 to the lower tilt section 54, thus returning to the eccentric arrangement in the upright position.

[0120] If the tilt angle d1 of the pole body 1 does not fall within the standard tilt angle d0 range when the tilt adjustment member 51 is rotated in one direction, the control unit 8 rotates the tilt adjustment member 51 in the opposite direction. For example, the control unit 8 can attempt to restore the tilt angle d1 to the reference tilt angle range d0 by rotating the tilt adjustment member 51 counterclockwise in one direction. However, since counterclockwise rotation is arbitrary, even if the tilt adjustment member 51 is rotated counterclockwise, the tilt angle d1 of the body 1 may not fall within the standard tilt range d0. That is, when the shaft c moves relative to the rotation axis rc towards the high tilt portion 55 due to the tilt of the body 1, the following situation may occur: due to the attempt to restore, the shaft c does not move from the high tilt portion 55 to the low tilt portion 54, but moves further towards the high tilt portion 55.

[0121] Since the tilt angles of the tilt adjustment member 51, including the low tilt portion 54 and the high tilt portion 55, are asymmetrical, it can be restored by clockwise rotation even if it cannot be restored by counterclockwise rotation. Therefore, the control unit 8 can attempt to restore the tilt d1 to the reference tilt range d0 by rotating the tilt adjustment member 51 in the opposite clockwise direction.

[0122] Thus, when attempting to restore the tilt d1 of the main body 1 of the utility pole, the tilt d1 of the main body 1 of the utility pole can be quickly restored by changing the direction of rotation.

[0123] According to various embodiments, the sensor unit 8 further includes a position sensor. The position sensor may include an ultrasonic sensor, a laser sensor, an infrared sensor, a proximity sensor, etc. For example, the control unit 8 can use the position sensor to identify the positions of the first point p1 and the second point p2 on the lower part of the body 1 of the low tilt portion 54 and the high tilt portion 55 of the tilt adjustment member 51.

[0124] In the above embodiment, the control unit 8 uses a position sensor to identify that the first point p1 is located in the low-slope section 54, while the second point p2 is located in the high-slope section 55. The slope d1 can be restored by positioning both the first point p1 and the second point p2 within the high-slope section 55. Therefore, the control unit 8 can acquire and utilize position information about the first point p1 and the second point p2, as well as section information about the low-slope section 54 and the high-slope section 55.

[0125] The control unit 8 can control the tilt adjustment member 51 to rotate counterclockwise or clockwise so that the first point p1 and the second point p2 are both positioned within the high tilt section 55.

[0126] The control unit 8 determines the direction in which the slope adjustment member 51 can quickly position the first point p1 and the second point p2 within the high slope section 55, whether clockwise or counterclockwise, and can rotate the slope adjustment member 51 in the determined direction.

[0127] Therefore, the tilt d1 of the main body 1 of the utility pole can be restored more quickly.

[0128] Figure 10 It shows how to... Figure 6 An example of applying vibration to the tilt adjustment member 51 to perform the tilt recovery function.

[0129] like Figure 10 As shown, the utility pole 20 also includes a vibration unit 56 that causes the tilt adjustment member 51 to vibrate in a predetermined direction. The vibration unit 56 may include an eccentric rotary vibration unit that generates vibration by rotating an unbalanced weight, a crank-type vibration unit that generates vibration by converting the rotational motion of a crankshaft into linear motion, a hydraulic vibration unit that generates vibration using a hydraulic cylinder, an electronic vibration unit that generates vibration using electromagnetic force, a piezoelectric vibration unit that generates vibration using the piezoelectric effect, etc.

[0130] When the tilt d1 of the main body 1 is not within the standard tilt range d0, the control unit 8 can control the vibration unit 56 to rotate the tilt adjustment member 51, so that the tilt adjustment member 51 vibrates.

[0131] The control unit 8 can control the drive unit 53 to rotate the tilt adjustment member 51 when the tilt adjustment surface 52 of the tilt adjustment member 51 is in contact with the lower part of the pole body 1. However, due to the friction between the tilt adjustment surface 52 and the lower part of the pole body 1, the rotation of the tilt adjustment member 51 may be unstable.

[0132] At this time, when vibration is applied to the tilt adjustment member 51 along the standing direction, the tilt adjustment member 51 lifts the lower part of the main body 1, and the contact state between the tilt adjustment surface 52 and the lower part of the main body 1 can be released instantaneously. Even though the contact release state is instantaneous, since the contact release state occurs periodically at the same time as the vibration is applied, if the drive unit 53 drives the tilt adjustment member 51 every moment, the tilt adjustment member 51 can be easily rotated.

[0133] In this way, by applying vibration to rotate the tilt adjustment member 51, the tilt adjustment member 51 can be easily rotated by reducing the frictional resistance generated by the vibration.

[0134] According to various embodiments, if the drive member 53 is arranged to support the tilt adjustment member 51, then when vibration is applied to the drive member 53, the vibration is transmitted to the tilt adjustment member 51 through the drive member 53, thus achieving the same effect as when vibration is applied directly to the tilt adjustment member 51.

[0135] According to different embodiments, a guide groove can be formed in the tilt adjustment surface 52, and the lower end of the main body 1 is inserted into the guide groove. For example, when the first point p1 and the second point p2 of the lower part of the main body 1 are inserted into the guide groove, the friction between the tilt adjustment surface 52 and the lower part of the main body 1 can be further reduced when the tilt adjustment member 51 rotates, so that the tilt adjustment member 51 can rotate easily.

[0136] Figure 11 An underground-supported tilt adjustment device 60 according to another embodiment of the present invention is shown. Figure 12 It shows the way Figure 11 An example of the rotating pressurizing unit 70 performing the tilt recovery function. Figure 13 Is with Figure 12 A cross-sectional view related to an example of performing the tilt recovery function. It is worth noting that... Figures 11 to 13 Only a portion of the main components are cut out and represented.

[0137] Below, for reference Figures 11 to 13 First, the structure of the tilt adjustment device 60 that realizes the tilt recovery function by rotating the pressure part 70 according to another embodiment of the present invention will be described, and the tilt recovery process will be described.

[0138] The pole tilt adjustment device 60 in this embodiment is used to adjust the tilt of the pole 30 supporting the overhead power distribution line a. Figure 1 The main body of the utility pole 1, etc., serves as pole 30.

[0139] The tilt adjustment device 60 includes a support frame 61, a rotary pressurization unit 70, a drive unit 74, a tilt sensor 75, and a control unit 8.

[0140] The support frame 61 can also be called a rotating support frame 61, to distinguish it from... Figure 1 The supporting frame 3, etc., is fixedly installed on the ground along the outer periphery of the lower part of the vertical utility pole 30. Figure 11 In this design, the support frame 61 is depicted as plate-shaped, but is not limited thereto. The support frame 61 can have various shapes and structures, and can be fixedly installed on the ground along the outer periphery of the lower part of the utility pole 30.

[0141] For example, the support frame 61 can be composed of a pair of separable, hinged sub-support frames. In the connected state, each of the pair of sub-support frames can have a ground pole receiving portion for the lower part of the pole 30 above the ground. Therefore, by separating the pair of sub-support frames and inserting the ground portion of the pole 30 buried in the ground b between them, and connecting the pair of sub-support frames to each other, the support frame 61 can be fixedly installed on the ground along the outer periphery of the ground portion of the pole 30 for each ground pole receiving portion.

[0142] The support frame 61 has a circular rotation guide 62 relative to the vertical axis pc. The rotation guide 62 can be a guide path that allows the rotating carrier 71 of the rotating pressure application part 70 (described later) to rotate stably along the vertical axis pc. For example, when the rotation guide 62 is set as a track, the rotating carrier 71 can include a wheel, rolling bearing, ball bearing, etc. that rolls along the track.

[0143] The rotating pressurizing unit 70 includes a rotating carrier 71 and a pusher 72. As described above, the rotating carrier 71 is supported on the support frame 61 and rotates along the rotating guide 62, and is configured to allow selection of a crimping position on the lower outer periphery of the utility pole 30. For example, the rotating carrier 71 can rotate freely on the lower outer periphery of the pole 30 while riding the rotating guide 62, and stop at a point selected as a predetermined connection position.

[0144] The actuator 72 is mounted on the rotating carrier 71 so that it can move radially along the vertical axis pc. For example, an actuator receiving portion can be formed inside the rotating carrier 71, allowing one end of the actuator 72 to be pulled out and inserted to the outside. The actuator receiving portion can be formed radially, and the actuator 72 can be received in the actuator receiving portion and then slide radially, causing one end to protrude outward. However, it is not limited to this; the actuator 72 can also be configured to slide radially on one side of the rotating carrier 71.

[0145] The actuator 72 has a pressure surface 73 that contacts the outer surface of the body 30 at its radially inner end. For example, the actuator 72 may be mounted on a rotating carrier 71 and configured to move forward or backward relative to the vertical axis pc at a selected pressurization position while rotating together with the rotating carrier 71.

[0146] The pressure surface 73 may have the same curvature as the outer surface of the rod 30 to stably contact the outer surface of the rod 30. Since the shape of the outer surface of the rod 30 can vary, the pressure surface 73 may be implemented using an elastic material, such as memory foam or rubber, which deforms according to the shape of the outer surface of the rod 30 when in contact with it.

[0147] However, even if the elastic pressing surface 73 contacts the outer surface of the rod 30, it may be difficult to maintain stable contact due to slippage between the surfaces. Therefore, the rod tilt adjustment device 60 may also include a connector to improve contact stability. For example, when a wire is used as the connector, the wire can be wrapped around the outer circumference of the pole 30 so that the pressing surface 73 contacts the outer circumference of the pole 30, and then the two ends of the wire can be fixed to the pusher 72. But it is not limited to this. In addition to wire, the connector can also be a clip, chain, Velcro, etc.

[0148] The drive unit 74 can be referred to as the actuator drive unit 74, in order to connect it with... Figure 1 The drive unit 74 is different from the drive unit 6 and drives the movement of the actuator 72 of the rotary pressurizing unit 70. For example, the drive unit 74 may include a high-power electric motor, a hydraulic actuator, a hydraulic cylinder, etc., and may be connected to the actuator 72 to provide driving force, so that the actuator 72 can slide forward or backward relative to the vertical axis pc. When the drive unit 74 uses a cylinder, the actuator 72 can slide radially while performing reciprocating piston movement within the cylinder.

[0149] The drive unit 74 can be connected to the rotating carrier 71 to provide driving force for the rotation of the rotating carrier 71. There can be multiple drive units 74, which can be divided into drive units 74 for the rotating carrier 71 and drive units 74 for the actuator 72, or they can be configured as an integrated unit including all of them.

[0150] The drive unit 74 is mounted on the rotating carrier 71 and rotates with the rotating carrier 71, but is not limited thereto. Therefore, it can be fixed to the support frame 61 to provide driving force to the rotating carrier 71 and the pusher 72 regardless of whether the rotating carrier 71 is rotating.

[0151] The tilt sensor 75 senses the tilt angle d1 of the rod 30 relative to the vertical axis pc. Because... Figure 1 The sensor portion 7 can be used as the tilt sensor 75 in this embodiment, so the tilt sensor 75 can use formula (1) to calculate the tilt angle d1 of the rod 30. The tilt sensor 75 can be set on one side of the rotating carrier 71, but is not limited thereto, and can also be set on the support frame 61.

[0152] Figure 1 The control unit 8 can also be used as the control unit 8 in this embodiment. The control unit 8 controls the drive unit 74 by moving the pusher 72 of the rotary pressurizing unit 70, which is in contact with the outer surface of the column 30, radially inward at the pressurizing position of the rotary carrier 71 selected according to the direction of the tilt d1 of the column 30, so that the size of the tilt d1 falls within the predetermined reference range d0.

[0153] For ease of explanation, assume that during the backfilling process, the column 30 remains upright. However, due to ground subsidence and other reasons, the axis c of the column 30 is tilted by an angle d1 relative to the upright axis pc, and the angle d1 is outside the standard angle range d0. For example, the control unit 8 calculates the slope change Δd according to formula (2). If the slope change Δd > 0, it is determined that the slope d1 of the main body of the utility pole 1 exceeds the reference slope range d0, and a restoration operation can be performed to make the slope d1 of the main body of the utility pole 1 fall into the reference slope range d0.

[0154] if Figure 13 The reference position pp0 shown is an arbitrary position used as a reference for the tilt direction of rod 30, the rotation direction of rotating carrier 71, etc. When rod 30 tilts in the opposite direction to the reference position pp0, it can be seen that the axis c of rod 30 has moved from the vertical axis pc in the opposite direction to the reference position pp0. At this time, it is preferable to restore the tilt d1 of rod 30 by pressing rod 30 at the pressure position pp2 opposite to the reference position pp0 and moving the axis c of rod 30 back to the reference position pp0.

[0155] Therefore, the control unit 8 controls the drive unit 74 so that the pusher 72 applies pressure to the outer surface of the coil 30 at the pressurized position pp2. When the force pushing the pusher 72 begins to be transmitted through the pressure surface 73 to the outer surface of the rod 30 toward the reference position pp0, the tilt angle d1 of the rod 30 begins to gradually recover. The control unit 8 can control the drive unit 74 to make the pusher 72 press the outer surface of the rod 30 until the tilt angle d1 falls within the predetermined reference range d0, thereby restoring the tilt angle d1 of the rod 30.

[0156] Meanwhile, when the pusher 72 presses against the outer surface of the pole 30, the support frame 61 may move relative to the ground due to the reaction force. In this case, the pressure of the pusher 72 may not be fully transmitted to the outer surface of the pole 30. Therefore, the pole tilt adjustment device 60 also includes a ground fixing member 77, which can firmly fix the support frame 61 to the ground, thereby preventing the support frame 61 from moving due to the reaction force generated when the pusher 72 presses against the outer surface of the pole 30.

[0157] The pole tilt adjustment device 60 can be used not only during this repair process, but also when the lower part 30 of the pole is initially buried in the ground. For example, in order to enable the pole 30 to be installed in an upright position, the pole tilt adjustment device 60 can keep the tilt d1 of the pole 30 within the standard tilt range d0.

[0158] In this way, unlike the operation in related technologies where workers approach the main body of the utility pole and manually use tools to restore the tilt according to the tilt of the main body of the utility pole, the pole tilt adjustment device 60 of this embodiment can effectively restore the tilt d1 according to the tilt of the pole 30, which not only makes the restoration work safer, but also improves the convenience and accuracy of the work.

[0159] According to various embodiments, the control unit 8 determines the pressure F of the actuator 72 according to the following formula (7) under the recovery angle dc calculated according to formula (3).

[0160] F=k·dc·A........................................Formula (7) Here, A can be the pressure area (m2) applied to the outer surface of the body 30, and F can be the pressure (N) applied by the pusher 72. The control unit 8 can control the drive unit 74 so that the pusher 72 presses the outer surface of the body 30 with a pressing force F determined according to this process.

[0161] Therefore, the optimal pressure F can be used, thus the slope d1 of coil 30 can be recovered more effectively.

[0162] According to various embodiments, the pole tilt control device 60 further includes a position sensor 76 that senses the position of the rotating carrier 71 on the lower outer periphery of the pole 30. The position sensor may include an encoder, an ultrasonic sensor, a laser sensor, an infrared sensor, a proximity sensor, etc.

[0163] For example, when an encoder is used as a position sensor 76, the encoder can use a unique angle code to provide the current angle information to the control unit 8. The control unit 8 can identify the current position pp1 of the rotating carrier 71 relative to the reference position pp0 in real time based on the received angle information.

[0164] The drive unit 74 drives the rotating carrier 71 to rotate. The control unit 8 sets the target pressurization position pp2 of the rotating carrier 71 corresponding to the tilt d1 of the rod 30, and controls the drive unit 74 to make the position of the rotating carrier 71 reach the target pressurization position pp2, thereby driving the rotating carrier 71 to rotate.

[0165] For ease of explanation, such as Figure 13 As shown, assume that the current position pp1 of the rotating carrier 71 is located at the reference position pp0. At this time, if the rod 30 tilts in the opposite direction to the reference position pp0, it is sometimes desirable to restore the tilt d1 of the rod 30 by applying pressure to the rod 30 at the pressure position pp2 on the opposite side of the reference position pp0.

[0166] Therefore, the control unit 8 can identify, based on the tilt value sensed by the tilt sensor 75, that the tilt direction d1 of the rod 30 is opposite to the reference position pp0, and set the target pressure position pp2 on the side opposite to the reference position pp0, corresponding to the tilt direction d1. The target pressure position pp2 can refer to the position of the rotating carrier 71 that can most effectively restore the tilt angle d1 by applying pressure through the pusher 72. If the direction of the tilt angle d1 is the same as in the previous example, then in this embodiment, the pressure position pp2 can be set as the target pressure position pp2.

[0167] The control unit 8 sets the target pressurization position pp2, and then controls the drive unit 74 to position the rotating carrier 71 at the target pressurization position pp2. The control unit 8 can use the position sensor 76 to check the current position pp1 of the rotating carrier 71 in real time, thereby identifying whether the current position pp1 of the rotating carrier 71 from the reference position pp0 corresponds to the target pressurization position pp2. When the rotating carrier 71 reaches the target pressurization position pp2, the pusher 72 mounted on the rotating carrier 71 can also reach the target pressurization position pp2.

[0168] When the pusher 72 reaches the pressurized position pp2, the control unit 8 can control the drive unit 74 to move the pusher 72 in the opposite direction of the tilt d1. As the pusher 72 presses against the outer surface of the rod 30, the tilt d1 of the rod 30 begins to gradually recover. The control unit 8 can control the drive unit 74 to press the pusher 72 against the outer surface of the rod 30 until the magnitude of the tilt d1 falls within a predetermined reference range d0.

[0169] If the slope change Δd < 0, then the tilt angle d1 is considered to be within the reference slope range d0, and the repair operation can be stopped. On the other hand, if the slope change Δd > 0, then the tilt angle d1 is considered to have not yet entered the reference slope range d0, and the recovery operation can continue.

[0170] Therefore, since the rotating carrier 71 can automatically reach the target pressurization position pp2, it is more convenient and accurate to restore the tilt d1 of the rod 30.

[0171] Figure 14 It shows when Figure 11 An example of displaying operation guidance information 83 when the rotating pressurizing unit 70 is manually operated.

[0172] In the tilt adjustment device 60 of this embodiment, the rotary pressure application part 70 further includes a rotary operation part 80 and a stop part 81. Other structures are similar to... Figure 11 As shown below, the description will focus on the rotary operating part 80 and the stop member 81.

[0173] A rotation operation unit 80 is provided on one side of the rotating carrier 71 so that the rotating carrier 71 can be held and rotated, and a stop member 81 is provided so that the rotating carrier 71 can be switched between a rotation-allowed state that allows the rotating carrier 71 to rotate and a rotation-restricted state that restricts the rotation of the rotating carrier 71.

[0174] Therefore, the worker can rotate the rotating carrier 71 along the rotating guide 62 while holding the rotating operating part 80, and can use the stop 81 to stably fix the rotating carrier 71 in a specific position. However, the shape and structure of the rotating operating part 80 and the stop 81 are not limited to... Figure 14 The shapes and structures shown can have various shapes and structures.

[0175] The tilt control device 60 in this embodiment further includes: a position sensor 76 for sensing the position of the rotating carrier 71 on the outer periphery of the rod 30 below the ground; and a display unit 82 for providing information. Figure 13 The position sensor 76 in the embodiment can be used as the position sensor 76 in this embodiment, and the display unit 82 can include a TV, monitor, PC, tablet computer, smartphone, etc. that uses LCD, LED, OLED, etc.

[0176] The control unit 8 sets the target pressurization position pp2 of the rotating carrier 71 corresponding to the tilt direction d1 of the electrode rod 30, and displays operation guidance information 83 on the display unit 82 on whether the target pressurization position pp2 and the position pp0 of the rotating carrier 71 correspond to each other, based on the position of the rotating carrier 71 sensed during the rotation operation.

[0177] For example, when a worker checks the tilt of the rod 30 and manually positions the rotating carrier 71 from its current position pp1 to the target pressurization position pp2 for restoration work, it may be difficult to accurately determine whether the current position pp1 of the rotating carrier 71 corresponds to the target pressurization position pp2.

[0178] Therefore, the control unit 8 sets the target pressurization position pp2 of the rotating carrier 71 according to the tilt direction d1 of the utility pole 30, and while the operator rotates the rotating carrier 71, the position sensor 76 monitors the current position pp1 of the rotating carrier 71 and displays the operation guidance information 83 on the display unit 82 to determine whether the current position pp1 of the rotating carrier 71 corresponds to the target pressurization position pp2. Thus, while looking at the operation guidance information 83, the operator can accurately match the current position pp1 of the rotating carrier 71 with the target pressurization position pp2.

[0179] For example, when setting the target pressurization position pp2 of the rotating carrier 71, the operation instruction information 83 may include the following statement: "Rotate the rotating carrier 71 by 180 degrees to position it at the target pressurization position pp2." When the operator rotates the rotating carrier 71, the operation instruction information 83 may include the following statement: "Rotate the rotating carrier 71 by another 10 degrees to reach the target pressurization position pp2." Therefore, even if the rotating carrier 71 is operated manually, the rotating carrier 71 can accurately reach the target pressurization position pp2, thereby making it easier and more accurate to restore the tilt d1 of the rod 30.

[0180] Figure 15 It is shown Figure 14 The diagram shows an example of the operation guidance information 83 when the direction of the tilt d1 changes.

[0181] The control unit 8 determines whether the tilt direction d1 of the electrode rod 30 changes as the rotary pressurizing unit 70 pressurizes. If the change in tilt direction d1 exceeds the predetermined allowable range, the control drive unit 74 stops the rotary pressurizing unit 70 from pressurizing, and resets the corrected pressurizing position pp3 of the rotating carrier 71 according to the changed tilt direction d1. The control unit 82 then displays the operation guidance information 84 corresponding to the corrected pressurizing position pp3. When manually restoring the tilt angle d1 of lever 30, lever 30 may tilt in an unexpected direction. For example, as Figure 14 As shown, after the worker positions the rotating carrier 71 at the target pressurization position pp2, the pusher 72 can be moved along a first direction t1 opposite to the tilt d1 direction under the control of the control unit 8. At this time, the operation instruction information 84 may include a statement indicating that pressurization is being applied in the first direction t1.

[0182] Of course, the tilt d1 of rod 30 can be restored along the initially desired first direction t1 by the pressure of pusher 72, but due to ground structure and other reasons, it may be restored along a direction different from the first direction t1. Even if the contact stability between the pressure surface 73 of pusher 72 and the outer surface of electrode rod 30 is improved by using a connector, it may still tilt along a direction different from the initially expected first direction t1.

[0183] In this situation, the control unit 8 can identify the change in tilt direction, d1. The change in slope direction, d1, is calculated as the angular difference between the initially expected first direction, t1, and the actual direction of change, and can be calculated using the vector (Vt1) = (xt1, yt1) of the first direction, t1, and the vector (Va) = (xa, ya) of the direction of change. When the change in direction exceeds a predetermined allowable range, the control unit 8 can control the drive unit 74 to stop applying pressure to the actuator 82.

[0184] Then, the control unit 8 resets the corrected pressure position pp3 of the rotating carrier 71 to a position corresponding to the direction of the changed tilt d1. The method for resetting the corrected pressurization position pp3 is the same as that for setting the target pressurization position pp2, which means that the position of the rotating carrier 71 that has changed tilt d1 due to the pressurization of the pusher 72 can be restored most effectively, and it can usually correspond to the direction of the change in tilt d1.

[0185] The control unit 8 can display operation guidance information 85 corresponding to the corrected pressurization position pp3, so that the operator can operate the rotation of the rotating carrier 71. This allows the operator to align the current position pp1 of the rotating carrier 71 with the corrected pressurization position pp3 while referring to the operation guidance information 85. For example, the operation guidance information 85 may include a statement such as: "The tilt d1 has not yet returned to the first direction t1. Position the rotating carrier 71 at the corrected pressure position pp3."

[0186] When the current position pp1 of the rotating carrier 71 corresponds to the corrected pressure position pp3 determined by the operator, the control unit 8 can control the drive unit 74 so that the pusher 72 presses against the outer surface of the electrode rod 30 along the second direction t2 until the inclination d1 at the corrected pressure position pp3 falls within a predetermined reference range d0. Since the second direction t2 can be the opposite direction to the change in inclination angle d1, the inclination d1 of the rod 30 can be restored by applying pressure in the second direction t2.

[0187] Therefore, while manually restoring the tilt d1 of the rod 30, even if the rod 30 tilts in an unexpected direction, the tilt d1 can be adjusted at the corrected pressure position pp3, so that the tilt d1 of the rod 30 can be adaptively restored to various situations.

[0188] According to various embodiments, when using such Figure 1 When the overhead power distribution line pole device 10 shown is used to bury the main body 1 of the pole, or when using, for example Figure 6 When the overhead power distribution line pole device 20 shown is installed with the main body 1 of the pole, it can be used together as follows: Figure 11 The lever tilt adjustment device 60 is shown. For example, the control drive unit 6 slides at least one of the plurality of tilt adjustment members 5, such that... Figure 1 If the tilt angle of the main body 1 is within the predetermined reference tilt angle range d0, it can be installed together as follows: Figure 11 The main tilt adjustment device 60 shown is used to restore the tilt d1.

[0189] More specifically, the control unit 8 can identify the tilt angle d1 and its tilt direction of the utility pole body 1 based on the tilt angle value sensed by the sensor unit 7, and use the tilt angle adjustment member 5 to perform the above-mentioned recovery operation so that the tilt angle d1 of the utility pole body 1 falls within the reference tilt angle range d0. If it tilts in the opposite direction to the reference position pp0, the control unit 8 can simultaneously control the drive unit 74 to rotate the rotating carrier 71 to the pressurization position pp2 on the opposite side of the reference position pp0, and cause the pusher 72 to apply pressure to the outer surface at this position.

[0190] Therefore, the tilt angle d1 can be restored more quickly through the sliding of the tilt adjustment member 5 and the pressure of the pusher 72. In addition, since the repair is carried out simultaneously in the ground b and on the ground, the repair work can be carried out more stably.

[0191] Similarly, the control drive unit 53 rotates the tilt adjustment member 51, causing... Figure 6 If the tilt angle of the main body 1 is within the predetermined reference tilt angle range d0, they can be installed together. Figure 11 The tilt adjustment device 60, etc., is used to restore the tilt d1.

[0192] More specifically, the control unit 8 can control the drive unit 53 to rotate the tilt adjustment member 51 so that the tilt d1 of the pole body 1 is restored to the reference tilt range d0. If tilting in the opposite direction to the reference position pp0, the control unit 8 can simultaneously control the drive unit 74 to rotate the rotating carrier 71 to the pressurized position pp2 on the opposite side of the reference position pp0, and cause the pusher 72 to pressurize the outer surface at that position.

[0193] Therefore, the tilt d1 can be restored more quickly and stably by rotating the tilt adjustment component 51 and pressing the pusher 72.
