Description

Technical Field

[0001] The present invention relates to the technical field of cable overhead, and more specifically, it relates to a cable overhead device for laying photovoltaic lines. Background Art

[0002] As an energy transmission link connecting core devices such as photovoltaic modules, inverters, and transformers in a photovoltaic power generation system, the laying process quality of the cable directly restricts the optimization of the electric energy transmission efficiency. In the technical field of photovoltaic line laying, the overhead laying method has become the mainstream choice due to advantages such as low cost and easy maintenance.

[0003] To overcome the thermal expansion and contraction effect, when laying the cable overhead, a telescopic margin needs to be reserved for the cable between adjacent overhead poles, forming a natural bending shape. However, this laying form exposed to the external environment has significant defects under extreme climate conditions such as low temperature, rain, and snow. Snow and ice layers are likely to form on the top of the cable, resulting in an abnormal increase in the self-weight of the cable, further exacerbating the bending deformation. When the deformation amount exceeds the mechanical limit of the cable material, a cable breakage accident will occur, causing economic losses.

[0004] In the prior art, for the problem of cable snow and ice accumulation, manual de-icing or electro-mechanical de-icing equipment is mainly used. However, manual de-icing has low efficiency and high labor intensity, and the electro-mechanical equipment requires dedicated personnel on duty, making it difficult to achieve rapid response, resulting in the inability to guarantee the ice removal effect.

The end parts of the long rods of the two L-shaped rods are respectively rotatably provided on two side walls of the rotating frame. At the end of the short rod of the L-shaped rod, a slapping rod for slapping the cable is provided.

[0008] As a preferred technical solution of the present invention, the middle of the long rod of the L-shaped rod is hinged to one end of a connecting rod. The other end of the connecting rod is hinged to a sliding rod. The sliding rod is slidably provided on a sliding seat. The sliding seat is fixedly provided on the side wall of the rotating frame. A second spring is sleeved outside the sliding rod. Two ends of the second spring are respectively connected to the sliding seat and the end of the sliding rod hinged to the connecting rod. At the other end of the sliding rod away from the connecting rod, a wedge block is provided.

[0009] As a preferred technical solution of the present invention, a main rod is slidably provided on the top of the frame. At the upper end of the main rod, a pulling platform is provided. At the lower end of the main rod, a cross plate is provided. A third spring is sleeved outside the main rod. Two ends of the third spring are respectively connected to the frame and the cross plate. At both ends of the cross plate, upper pressing blocks for pressing the cable are provided.

[0010] As a preferred technical solution of the present invention, upper connecting rods are rotatably provided on both sides of the upper pressing block.

[0012] As a preferred technical solution of the present invention, a circular ring notch is provided on the main rod, and a locking pin for clamping the circular ring notch of the main rod is detachably provided on the upper part of the frame.

[0013] As a preferred technical solution of the present invention, the two side walls of the cross plate are provided with auxiliary rods, the auxiliary rods pass through the side walls of the frame, a triangular rod is provided below the end of the auxiliary rod, and a cross bar is provided below the triangular rod. An extension rod is extended from the end of the rotating frame close to the pin shaft, and a frustum is provided on the extension rod that cooperates with the triangular rod and the cross bar.

[0014] The beneficial effects of the present invention compared with the prior art are:

[0015] (1) When snow and ice begin to accumulate on the cable of the present invention, the overall weight of the cable increases, so the bending of the cable increases. At the same time, the force exerted by the cable on the secondary wheel increases, driving the rotating frame of the instantaneous vibration device to rotate downward, and the rotating frame drives the arc guide rod 1 to move synchronously. The arc guide rod 1 brings the push block to start contacting the unlocking inclined surface of the locking block, driving the locking block to slide in the direction of the frame, so that the locking block and the pressure rod are gradually separated. At the moment when the locking block and the pressure rod are separated, the increased weight on the cable is transmitted to the pressure rod through the arc spring 1, causing the pressure rod to rotate instantly, and the rotating frame also rotates downward instantly. The cable instantly loses the support of the secondary wheel, so the cable shakes up and down, thereby automatically removing the snow and ice on the cable through shaking, without the need for additional manual intervention.

[0016] (2) When the rotating frame of the instantaneous vibration device of the present invention rotates downward instantaneously, the rotating frame moves downward synchronously with the sliding rod and the wedge block, so that the inclined surface of the wedge block contacts the end of the arc-shaped guide rod 2, so that the sliding rod slides along the sliding seat in the direction of the secondary wheel, the spring 2 is compressed, and the power is transmitted through the connecting rod to rotate the L rod, and the L rod drives the hitting rod to hit the cable, causing the cable to vibrate horizontally, thereby further clearing the snow and ice on the cable.

[0017] (3) When the cable is pulled on the main wheel, the locking pin is inserted into the notch of the main rod to ensure that the main rod remains in the upper position. The crossbar driving truncated table of the triangular rod is also in the upper position. The power is transmitted through the extension rod so that the ends of the rotating frames of all instantaneous vibration devices close to the secondary wheel are kept in a downward tilted state, and the arc spring 1 and the arc spring 2 are kept in a compressed state, that is, when the cable is pulled in the main wheel, the cable does not contact the secondary wheel, thereby avoiding repeated triggering of the instantaneous vibration device.

[0018] When the cable laying is completed in the present invention, the locking pin is removed to separate the locking pin from the circular notch of the main rod. Under the action of the third spring, the main rod and the cross plate move downward. The cross plate drives the two upper pressing blocks to approach the cable. At the same time, the lower pressing block also approaches the cable, so that the shock pads on the arc concave surfaces of the upper pressing block and the lower pressing block clamp the cable simultaneously, thus completing the fixation of the cable and preventing the cable from displacing on this device.

[0032] Embodiment: Please refer to Figure 1-11 the structural schematic diagram. The present invention provides the following technical solution: A cable overhead device for laying photovoltaic lines, including a frame 1. A main wheel 2 for supporting the cable 3 is rotatably provided at the center of the frame 1. Vibration instantaneous devices are symmetrically provided on both sides of the main wheel 2 on the frame 1.

[0033] The vibration instantaneous device includes two pin shafts 4 respectively fixed on two side walls of the frame 1. A rotating frame 5 is rotatably provided by the two pin shafts 4. An auxiliary wheel 6 is rotatably provided at the end of the rotating frame 5. A stop block 7 for blocking the upward rotation of the rotating frame 5 is provided on the frame 1. Base ones 8 are perpendicularly provided on both side walls of the rotating frame 5. An arc guide rod one 9 is fixedly provided below the base one 8. Pressing rotating rods 10 are also rotatably provided on the pin shafts 4 outside the rotating frame 5. The end of the pressing rotating rod 10 forms a sliding fit with the arc guide rod one 9. An arc spring one 11 is sleeved outside the arc guide rod one 9. Two ends of the arc spring one 11 are respectively connected with the base one 8 and the pressing rotating rod 10. A pushing block 12 is provided at the lower end of the arc guide rod one 9.

[0034] The instantaneous vibration device further includes two locking blocks 13 for blocking the downward rotation of the pressure turning rod 10. The two locking blocks 13 are respectively slidably arranged on two side walls of the frame 1, and a first spring 14 is connected between the locking block 13 and the side wall of the frame 1. The locking block 13 is provided with an unlocking inclined surface 1301 in contact with the pushing block 12. An arc-shaped guide rod two 15 is slidably arranged in the middle of the pressure turning rod 10. The lower end of the arc-shaped guide rod two 15 is arranged on the second base 17, and the second base 17 is fixedly arranged on the side wall of the frame 1. An arc-shaped spring two 16 is sleeved outside the arc-shaped guide rod two 15, and both ends of the arc-shaped spring two 16 are connected to the pressure turning rod 10 and the second base 17 respectively.

[0035] Specifically, when laying the cable 3 overhead, this device is arranged on each overhead pole. The cable 3 is placed on the main wheel 2, and the main wheel 2 rotates in the frame 1, which is convenient for dragging the cable 3. When the laying of the cable 3 is completed, both the arc-shaped spring one 11 and the arc-shaped spring two 16 are in their original compressed lengths. The upper plane of the locking block 13 contacts the pressure turning rod 10, and the stop block 7 contacts the upper plane of the rotating frame 5 to prevent the rotating frame 5 from rotating upward and ensure that the rotating frame 5 is in a horizontal state. Therefore, the cable 3 is also erected on the auxiliary wheel 6.

[0036] When snow and ice accumulate on the cable 3, the overall weight of the cable 3 increases, so the bending of the cable 3 increases. At the same time, the force exerted by the cable 3 on the auxiliary wheel 6 increases, driving the rotating frame 5 of the instantaneous vibration device to rotate downward. The rotating frame 5 drives the first base 8 and the arc-shaped guide rod one 9 to move synchronously. Since the locking block 13 blocks the rotation of the pressure turning rod 10, the arc-shaped guide rod one 9 slides in the end of the pressure turning rod 10, and the arc-shaped spring one 11 is compressed. The arc-shaped guide rod one 9 drives the pushing block 12 to start contacting the unlocking inclined surface 1301 of the locking block 13, driving the locking block 13 to slide towards the frame 1. Therefore, the locking block 13 gradually disengages from the pressure turning rod 10, and the first spring 14 is compressed. At the moment when the locking block 13 disengages from the pressure turning rod 10, due to the increased weight on the cable 3, it is transmitted to the pressure turning rod 10 through the arc-shaped spring one 11, causing the pressure turning rod 10 to rotate instantaneously, and the rotating frame 5 also rotates downward instantaneously. The cable 3 instantly loses the support of the auxiliary wheel 6, and the cable 3 generates up and down vibrations, thereby removing the snow and ice on the cable 3 through the vibrations.

[0037] In order to intensify the vibration of the cable 3, the instantaneous vibration device further includes two L-shaped rods 18. The lengths of the long rods of the two L-shaped rods 18 are inconsistent. The end parts of the long rods of the two L-shaped rods 18 are respectively rotatably arranged on two side walls of the rotating frame 5, and a slapping rod 19 for slapping the cable 3 is arranged at the end part of the short rod of the L-shaped rod 18.

[0038] The middle of the long rod of the L-shaped rod 18 is hinged to one end of the connecting rod 20. The other end of the connecting rod 20 is hinged with a sliding rod 21. The sliding rod 21 is slidably arranged on the sliding seat 22. The sliding seat 22 is fixedly arranged on the side wall of the rotating frame 5. A second spring 23 is sleeved outside the sliding rod 21. The two ends of the second spring 23 are respectively connected to the sliding seat 22 and the end of the sliding rod 21 hinged with the connecting rod 20. A wedge block 24 is arranged at the other end of the sliding rod 21 far from the connecting rod 20.

[0039] Specifically, when the rotating frame 5 instantaneously rotates downward, the rotating frame 5 drives the sliding rod 21 and the wedge block 24 to move downward synchronously, so that the inclined surface of the wedge block 24 contacts the end of the arc-shaped guide rod II 15. Therefore, the sliding rod 21 slides along the sliding seat 22 towards the auxiliary wheel 6, and the second spring 23 is compressed. The power is transmitted through the connecting rod 20 to make the L-shaped rod 18 rotate. The L-shaped rod 18 drives the hitting rod 19 to hit the cable 3. Since the lengths of the long rods of the two L-shaped rods 18 are inconsistent, the positions where the hitting rod 19 hits the cable 3 are also different, causing the cable 3 to generate lateral jitter, further removing the snow and ice on the cable 3.

[0040] In order to fix the cable 3, a main rod 25 is slidably arranged on the top of the machine frame 1. A pulling platform 26 is arranged at the upper end of the main rod 25. A cross plate 27 is arranged at the lower end of the main rod 25. A third spring 28 is sleeved outside the main rod 25. The two ends of the third spring 28 are respectively connected to the machine frame 1 and the cross plate 27. Upper pressing blocks 29 for pressing the cable 3 are arranged at both ends of the cross plate 27.

[0041] Upper connecting rods 30 are rotatably arranged on both sides of the upper pressing block 29. A slider 31 is rotatably arranged at the lower end of the upper connecting rod 30. The slider 31 is slidably arranged on a slide bar 32. The slide bar 32 is fixedly arranged on the machine frame 1. The slider 31 is rotatably connected to the upper end of a lower connecting rod 33. The lower end of the lower connecting rod 33 is rotatably connected to a lower pressing block 34 that cooperates with the upper pressing block 29. A guide rod 35 is arranged below the lower pressing block 34. The guide rod 35 is slidably arranged on a guide seat 36. The guide seat 36 is fixedly arranged on the machine frame 1.

[0042] The lower surface of the upper pressing block 29 is an arc concave surface. The upper surface of the lower pressing block 34 is an arc concave surface. Shock-absorbing pads are arranged on the arc concave surfaces of the upper pressing block 29 and the lower pressing block 34.

[0043] A circular ring notch is arranged on the main rod 25. A locking pin 37 for clamping the circular ring notch of the main rod 25 is detachably arranged on the upper part of the machine frame 1.

[0044] Specifically, when laying the cable 3, the main rod 25 is in the upper position, and the circular ring notch on the main rod 25 is located outside the frame 1. The locking pin 37 is inserted into the circular ring notch of the main rod 25 to ensure that the main rod 25 remains in the upper position. When the cable 3 is laid, it is necessary to fix the cable 3. Remove the locking pin 37 to separate the locking pin 37 from the circular ring notch of the main rod 25. Under the action of the third spring 28, the main rod 25 and the cross plate 27 move downward, and the cross plate 27 drives the two upper pressing blocks 29 to approach the cable 3. At the same time, power is transmitted through the upper connecting rod 30, so that the slider 31 slides along the slide bar 32 away from the main rod 25, and then power is transmitted through the lower connecting rod 33, so that the guide rod 35 slides upward along the guide seat 36, so the lower pressing block 34 is synchronously close to the cable 3. The upper pressing block 29 and the lower pressing block 34 approach the cable 3 synchronously, so that the shock-absorbing pads on the arc concave surfaces of the upper pressing block 29 and the lower pressing block 34 clamp the cable 3 at the same time, thus completing the fixation of the cable 3 and preventing the cable 3 from displacing on this equipment.

[0045] During the process of laying the cable 3, when the cable 3 is towed on the main wheel 2, in order to avoid repeatedly triggering the transient vibration device, auxiliary rods 38 are provided on both side walls of the cross plate 27. The auxiliary rods 38 pass through the side wall of the frame 1. Below the end of the auxiliary rod 38, a triangular rod 39 is provided. Below the triangular rod 39 is a cross bar. An extension rod 40 is extended at the end of the rotating frame 5 close to the pin shaft 4, and a round platform 41 that cooperates with the cross bar of the triangular rod 39 is provided on the extension rod 40.

[0046] Specifically, when the main rod 25 is in the upper position, the cross plate 27 drives the auxiliary rod 38 and the triangular rod 39 to be in the upper position as well. Therefore, the cross bar of the triangular rod 39 drives the round platform 41 to be in the upper position. Through the transmission of power by the extension rod 40, the ends of the rotating frames 5 of all the transient vibration devices close to the auxiliary wheel 6 are kept in a downward inclined state, that is, to ensure that when the cable 3 is towed in the main wheel 2, the cable 3 does not contact the auxiliary wheel 6, avoiding repeatedly triggering the transient vibration device.

[0047] Working principle: This equipment is installed on each overhead line pole. In the initial state, the locking pin 37 is inserted into the circular ring notch of the main rod 25 to ensure that the main rod 25 remains in the upper position. At this time, the main rod 25 drives the cross plate 27, the auxiliary rod 38 and the triangular rod 39 to be in the upper position as well. Therefore, the cross bar of the triangular rod 39 drives the round platform 41 to be in the upper position. Through the transmission of power by the extension rod 40, the ends of the rotating frames 5 of all the transient vibration devices close to the auxiliary wheel 6 are kept in a downward inclined state, and the first arc spring 11 and the second arc spring 16 are kept in a compressed state, that is, to ensure that when the cable 3 is towed in the main wheel 2, the cable 3 does not contact the auxiliary wheel 6, avoiding repeatedly triggering the transient vibration device.

[0048] When the cable 3 is laid, the lock pin 37 is removed to separate the lock pin 37 from the circular notch of the main rod 25. Under the action of the spring 3 28, the main rod 25 and the cross plate 27 move downward, and the cross plate 27 brings the two upper pressing blocks 29 closer to the cable 3. At the same time, the power is transmitted through the upper connecting rod 30, so that the slider 31 slides along the slide bar 32 away from the main rod 25, and then the power is transmitted through the lower connecting rod 33, so that the guide rod 35 slides upward along the guide seat 36, so that the lower pressing block 34 is synchronously moved closer to the direction of the cable 3. The upper pressing block 29 and the lower pressing block 34 are synchronously moved closer to the direction of the cable 3, so that the shock-absorbing pads on the arc concave surfaces of the upper pressing block 29 and the lower pressing block 34 clamp the cable 3 at the same time, thereby completing the fixation of the cable 3 and preventing the cable 3 from being displaced on the device.

[0049] When the cable 3 is fixed, that is, the cross plate 27 and the auxiliary rod 38 move to the lower position, the cross bar of the triangular rod 39 is separated from the round table 41, the arc spring 11 and the arc spring 2 16 restore the original compression length, and the instantaneous vibration device returns to the standby state. At this time, the upper plane of the locking block 13 contacts the pressure rod 10 to prevent the pressure rod 10 from rotating downward, and the stopper 7 contacts the upper plane of the rotating frame 5 to prevent the rotating frame 5 from rotating upward, ensuring that the rotating frame 5 is in a horizontal state, so the cable 3 is also mounted on the auxiliary wheel 6. When snow and ice begin to accumulate on the cable 3, the overall weight of the cable 3 increases, so the bending of the cable 3 increases. At the same time, the force of the cable 3 on the secondary wheel 6 increases, driving the rotating frame 5 of the instantaneous vibration device to rotate downward, and the rotating frame 5 drives the seat 8 and the arc guide rod 9 to move synchronously. Since the locking block 13 blocks the rotation of the pressure rod 10, the arc guide rod 9 slides on the pressure rod 10, the arc spring 11 is compressed, and the arc guide rod 9 starts to contact the unlocking inclined surface 1301 of the locking block 13 with the push block 12, driving the locking block 13 to slide in the direction of the frame 1, so the locking block 13 gradually separates from the pressure rod 10, and the spring 14 is compressed. At the moment the locking block 13 disengages from the pressure-turning rod 10, the increased weight on the cable 3 is transmitted to the pressure-turning rod 10 through the arc spring 11, causing the pressure-turning rod 10 to rotate instantly, and the rotating frame 5 also rotates downward instantly. The cable 3 instantly loses the support of the secondary wheel 6, and the cable 3 shakes up and down, thereby removing the snow and ice on the cable 3 through shaking.

[0050] When the rotating frame 5 rotates downward instantly, the rotating frame 5 moves downward synchronously with the slide bar 21 and the wedge block 24, so that the inclined surface of the wedge block 24 contacts the end of the arc-shaped guide rod 21, so that the slide bar 21 slides along the slide seat 22 toward the auxiliary wheel 6, the spring 23 is compressed, and the power is transmitted through the connecting rod 20, so that the L rod 18 rotates, and the L rod 18 drives the slapping rod 19 to hit the cable 3. Since the lengths of the long rods of the two L rods 18 are different, the positions where the slapping rod 19 hits the cable 3 are also different, so that the cable 3 produces a lateral shake, and the snow and ice on the cable 3 are further cleared.

[0051] When the snow and ice on the cable 3 are cleared, the weight of the cable 3 returns to the initial state, and under the action of the arc spring one 11 and the arc spring two 16, the transient vibration device returns to the standby state again.

[0052] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve substantially the same technical problems and achieve substantially the same technical effects are all covered by the protection scope of the present invention.
