[0001] The invention relates to the technical field of tension regulation, and in particular to a tension release and retraction regulating device for a high-voltage overhead power transmission line. Background Art

[0002] High-voltage overhead transmission lines are important infrastructure for power transmission. They are mainly composed of poles, towers, conductors, insulators, hardware and other parts.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention sets a retracting and releasing mechanism. When the circuit of the high-voltage line needs to be adjusted, the servo motor drives the rotating shaft and the drum to rotate, so that the high-voltage line is contracted or released, thereby changing the tension of the high-voltage line. In this process, there is friction between the electric line and the drum. The high-voltage line is repeatedly wound and released on the drum, which will cause wear on the surface of the drum. Especially when the retracting and releasing speed is fast or the line tension is large, the wear is more obvious. Scratches or pits may appear on the surface of the worn drum, which will not only affect the winding quality of the line, but also may damage the outer insulation layer of the transmission line. By installing a row of small pulleys on the edge of the drum, the transmission line contacts the drum through the pulleys during the retracting and releasing process, and the sliding friction between the transmission line and the drum is converted into rolling friction of the pulley, which greatly reduces the friction.

[0014] 2. The present invention sets up a detection mechanism, and the high-voltage wire will pass through the sleeve rod and generate a continuous pressure on the sleeve rod. This pressure will be transmitted to the pressure sensor. When the pressure changes, the pressure sensor will convert the pressure change into an electrical signal and transmit it to the signal receiver through the signal transmitter, so that the servo motor drives the overall retracting and extending mechanism to start working.

[0015] 3. The present invention sets a cleaning mechanism. The servo motor 2 can drive the rotating shaft 2 and the gear to rotate through the energy absorbed by the solar panel, and drive the cleaning mechanism to start working, so that the support plate 4 and the tooth block will rotate along the groove, thereby driving the brush to come into contact with the retracted high-voltage line and brushing off the dust on the high-voltage line, avoiding the dust and impurities affecting the pressure inspection during the contraction of the high-voltage line and increasing the friction of the high-voltage line wrapped around the reel. The change of direction increases the tension. At the same time, since the high-voltage frame is at a high place and the external wind force is relatively large, the wind force will blow the wind shield blades, thereby causing the rotating rod to rotate, increasing the brushing force of the brush. At the same time, the rotation of the brush will come into contact with the scraper at the bottom, causing the dust and impurities on the brush to fall from the ash leakage gap, thereby achieving self-cleaning.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, using Figure 1-Figure 8 A tension release and retraction adjustment device for a high-voltage overhead transmission line according to one embodiment of the present invention is described as follows.

[0027] like Figure 1As shown, a tension release and retraction adjustment device for a high-voltage overhead transmission line of the present invention comprises: a base 1, a main column 2 is fixedly connected to the top of the base 1, side columns 3 are evenly arranged on the outer surface of the main column 2, the top of the side columns 3 is fixedly connected to the outer surface of the main column 2, a support frame 4 is fixedly connected to the top of the main column 2, a support rod 5 is fixedly connected to the outer surface of the support frame 4, and a circuit unit 6 is fixedly connected to the end of the support rod 5 away from the support frame 4; When the present invention is working, high voltage electricity will be transmitted through the high voltage line 64. In the new construction of high voltage overhead transmission lines, the tension of the line can be accurately controlled through the circuit unit 6 to avoid damage to the line due to collision with the ground or other obstacles. When replacing damaged line segments or adjusting the sag of the line, this tension release and adjustment device is also required to ensure the safe operation of the line and the appropriate tension state.

[0028] like Figure 2-Figure 3 As shown, the circuit unit 6 includes a power board 61, two ends of the power board 61 are fixedly connected with ports 62, the outer surface of the port 62 is fixedly connected to the two ends of the power board 61, the side of the port 62 away from the power board 61 is fixedly connected with a winding column 63, the outer surface of the port 62 is fixedly connected with a high-voltage line 64, the outer surface of the power board 61 is fixedly connected with a connecting plate 65, the end of the connecting plate 65 away from the power board 61 is fixedly connected with a casing 66, the end of the casing 66 away from the connecting plate 65 is fixedly connected with a pre-processing mechanism 67, the outer surface of the casing 66 is fixedly connected with a detection mechanism 68, the inner wall of the casing 66 is fixedly connected with a retracting mechanism 69, the inner wall of the casing 66 is symmetrically provided with a support plate 1 610, the outer surface of the support plate 1 610 is fixedly connected with a brake telescopic rod 611, the output end of the brake telescopic rod 611 is fixedly connected with a jacket 612, and the end of the casing 66 close to the pre-processing mechanism 67 is fixedly connected with a positioning plate 613; When working, the detection mechanism 68 will first detect the tension of the high-voltage line. When the tension changes significantly, the retracting and releasing mechanism 69 will retract and release the high-voltage line 64, thereby changing the tension to a normal level.

[0029] like Figure 4 As shown, the retracting and releasing mechanism 69 includes a servo motor 691, a signal receiver 692 is fixedly connected to the outer surface of the servo motor 691, a rotating shaft 693 is fixedly connected to the output end of the servo motor 691, a reel 694 is fixedly connected to the end of the rotating shaft 693 away from the servo motor 691, a pulley 695 is evenly arranged on the end of the reel 694 away from the rotating shaft 693, and the outer surface of the pulley 695 is rotatably connected to the end of the reel 694 away from the rotating shaft 693.

[0030] When the circuit of the high-voltage line 64 needs to be adjusted, the servo motor 691 will drive the rotating shaft 693 and the reel 694 to rotate, so that the high-voltage line 64 will be contracted or released, thereby changing the tension of the high-voltage line 64. In this process, there is friction between the electric line and the reel 694. The high-voltage line 64 is repeatedly wound and released on the reel 694, which will cause wear on the surface of the reel 694. Especially in the case of fast retraction speed or high line tension, the wear is more obvious. Scratches or pits may appear on the surface of the worn reel 694, which will not only affect the winding quality of the line, but also may damage the outer insulation layer of the transmission line. By installing a row of small pulleys 695 on the edge of the reel 694, the transmission line contacts the reel 694 through the pulleys 695 during the retraction process, and the sliding friction between the transmission line and the reel 694 is converted into rolling friction of the pulleys 695, which greatly reduces the friction.

[0031] The outer surface of the power board 61 is fixedly connected to the end of the support rod 5 away from the support frame 4, and the outer surface of the servo motor 691 is fixedly connected to the inner wall of the casing 66.

[0032] The outer surface of the high-voltage wire 64 is sleeved with the outer surface of the winding column 63 , the outer surface of the high-voltage wire 64 is sleeved with the outer surface of the reel 694 , and the outer surface of the high-voltage wire 64 is slidably connected with the outer surface of the pulley 695 .

[0033] like Figure 5 As shown, the detection mechanism 68 includes a protruding plate 681, the inner wall of the protruding plate 681 is fixedly connected to the support plate 682, the outer surface of the support plate 682 is fixedly connected to the pressure sensor 683, the outer surface of the pressure sensor 683 is fixedly connected to the signal transmitter 684, and the side of the pressure sensor 683 away from the support plate 682 is fixedly connected to the sleeve rod 685.

[0034] The high-voltage wire 64 will pass through the sleeve rod 685 and generate a continuous pressure on the sleeve rod 685, and this pressure will be transmitted to the pressure sensor 683. When this pressure changes, the pressure sensor 683 will convert the pressure change into an electrical signal and transmit it to the signal receiver through the signal transmitter 684, so that the servo motor 691 drives the overall retracting and releasing mechanism 69 to start working.

[0035] Both ends of the protruding plate 681 are fixedly connected to the inner wall of the protruding plate 681 , and the inner wall of the sleeve rod 685 is slidably connected to the outer surface of the high-voltage line 64 .

[0036] The specific workflow is as follows: During operation, the high-voltage line 64 will pass through the sleeve rod 685 and generate a continuous pressure on the sleeve rod 685, and this pressure will be transmitted to the pressure sensor 683. When this pressure changes, the pressure sensor 683 will convert the pressure change into an electrical signal and transmit it to the signal receiver through the signal transmitter 684. Then, the servo motor 691 will drive the rotating shaft 693 and the reel 694 to rotate, thereby contracting or releasing the high-voltage line 64, thereby changing the tension of the high-voltage line 64. By installing a row of small pulleys 695 on the edge of the reel 694, the transmission line is in contact with the reel 694 through the pulley 695 during the retraction and release process, and the sliding friction between the transmission line and the reel 694 is converted into the rolling friction of the pulley 695, which greatly reduces the friction.

[0037] Embodiment 2, use Figure 1-8 The figure illustrates a tension release and adjustment device for a high-voltage overhead transmission line according to one embodiment of the present invention as follows.

[0038] like Figure 6 As shown, a tension release and adjustment device for a high-voltage overhead transmission line of the present invention is based on the first embodiment, and the pretreatment mechanism 67 includes a support plate three 671, the outer surface of the support plate three 671 is fixedly connected to a servo motor two 672, the output end of the servo motor two 672 is fixedly connected to a rotating shaft two 675, the end of the rotating shaft two 675 away from the servo motor two 672 is fixedly connected to a gear 676, the top of the servo motor two 672 is fixedly connected to a support rod two 673, the top of the support rod two 673 is fixedly connected to a solar panel 674, and the outer surface of the gear 676 is meshed with a cleaning mechanism 677.

[0039] The servo motor 672 can drive the second rotating shaft 675 and the gear 676 to rotate through the energy absorbed by the solar panel 674, and drive the cleaning mechanism 677 to start working.

[0040] like Figure 7-Figure 8 As shown, the cleaning mechanism 677 includes a circular plate 6771, the outer surface of the circular plate 6771 is provided with a groove 6772, the outer surface of the groove 6772 is slidably connected with a slider 6773, the outer surface of the slider 6773 is fixedly connected with a support plate four 6774, the outer surface of the support plate four 6774 is fixedly connected with a tooth block 6775, the tooth block 6775 is arranged on the periphery of the support plate four 6774, the inner wall of the support plate four 6774 is rotatably connected with a rotating rod 6776, one end of the rotating rod 6776 is fixedly connected with a wind shield blade 6777, the outer surface of the rotating rod 6776 is evenly provided with brushes 6778, the bottom of the circular plate 6771 is provided with an ash leakage notch 6779, the outer surface of the ash leakage notch 6779 is fixedly connected with a support rod three 67710, and the top of the support rod three 67710 is fixedly connected with a scraper 67711.

[0041] As the gear 676 rotates, the support plate 4 6774 and the tooth block 6775 will rotate along the groove 6772, thereby driving the brush 6778 to come into contact with the retracted high-voltage wire 64 and brush off the dust on the high-voltage wire 64, so as to prevent dust and impurities from affecting the pressure inspection during the contraction of the high-voltage wire 64 and increase the friction of the high-voltage wire 64 wrapped around the reel 694. At the same time, the external wind will blow the wind shield blade 6777, so that the rotating rod 6776 will rotate, increasing the brushing force of the brush 6778. At the same time, the rotation of the brush 6778 will come into contact with the scraper 67711 at the bottom, so that the dust and impurities on the brush 6778 will fall from the dust leakage gap 6779, thereby achieving self-cleaning.

[0042] The wind shield blade 6777 is arranged on the outer side of the circular plate 6771 , and the brush 6778 is arranged on the inner wall of the circular plate 6771 .

[0043] The outer surface of the circular plate 6771 is fixedly connected to the outer surface of the support plate 3 671 , and the outer surface of the gear 676 is meshed with the gear block 6775 .

[0044] The specific workflow is as follows: During operation, the servo motor 2 672 can drive the rotating shaft 2 675 and the gear 676 to rotate through the energy absorbed by the solar panel 674, and drive the cleaning mechanism 677 to start working, which will cause the support plate 4 6774 and the tooth block 6775 to rotate along the groove 6772, thereby driving the brush 6778 to come into contact with the retracted high-voltage wire 64 and brush off the dust on the high-voltage wire 64, thereby preventing dust and impurities from affecting the pressure inspection during the contraction of the high-voltage wire 64 and increasing the friction of the high-voltage wire 64 wrapped around the reel 694. The change of direction increases the tension. At the same time, since the high-voltage frame is at a high place and the external wind force is relatively strong, the wind force will blow the wind shield blade 6777, thereby causing the rotating rod 6776 to rotate, increasing the cleaning force of the brush 6778. At the same time, the rotation of the brush 6778 will come into contact with the scraper 67711 at the bottom, causing the dust and impurities on the brush 6778 to fall from the ash leakage gap 6779.
