DETAILED DESCRIPTION
[0029] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0030] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.
[0031] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0032] One of the preferred embodiments of the present application is as follows: Figures 1 to 13 As shown, an intelligent monitoring device for overhead lines includes a monitoring module 11, a winding mechanism 2 and a switch assembly 3. The monitoring module 11 is installed at a high altitude and is used to monitor the conductor 1 (i.e., the transmission line at a high altitude) in real time. The winding mechanism 2 is installed at a high altitude and cooperates with the conductor 1. The switch assembly 3 is installed on the winding mechanism 2 and is electrically connected to the winding mechanism 2.
[0033] It is understandable that under normal circumstances, the reeling mechanism 2 is not in operation, and the reeling mechanism 2 can also play a supporting role for the overhead wire 1. Figure 4 As shown, under the action of gravity, the wire 1 will sag and squeeze the switch assembly 3, so the switch assembly 3 will be triggered, and the switch assembly 3 will change from the original open state to the closed state, and then the winding mechanism 2 will be started, so that the wire 1 will be lifted under the action of the winding mechanism 2, and then the broken end will be lifted to a high altitude and away from the ground. In this way, the potential safety hazard caused by the broken wire 1 falling directly on the ground is avoided. In addition, the monitoring module 11 can monitor the operating status of the wire 1 in real time. Once an abnormal situation is detected, such as wire 1 breakage, overload, etc., the monitoring module 11 will immediately send an alarm signal and send the alarm information to the ground monitoring center through wireless transmission, so that corresponding emergency repair measures can be taken in time, which greatly improves safety.
[0034] It should be known that the above-mentioned winding mechanism 2 and monitoring module 11 are installed at a high altitude, that is, installed at a position of an electric pole or a tower that suspends the conductor 1.
[0035] In one embodiment of the present application, the winding mechanism 2 includes a frame 203, a driving device 204, an upper roller 201 and a lower roller 202. The frame 203 is installed on a high-altitude iron tower or a telephone pole through a support frame. The lower roller 202 is rotatably installed at the bottom end of the frame 203. The upper roller 201 is rotatably installed at the top end of the frame 203 and corresponds to the lower roller 202. The two rollers correspond to each other up and down, and the conductor 1 is against the upper roller 201 and the lower roller 202. The driving device 204 is installed on the frame 203 and the output end is matched with the upper roller 201 and the lower roller 202. The driving device 204 is electrically connected to the switch component 3.
[0036] It is understandable that when the wire 1 is broken, the switch assembly 3 is triggered to start the driving device 204, and the driving device 204 drives the upper roller 201 and the lower roller 202 to rotate relative to each other. Figure 5 As shown in (b), the upper roller 201 rotates clockwise, the lower roller 202 rotates counterclockwise, and the broken part of the wire 1 is on the right side, so the wire 1 will move to the left under the drive of the two rollers, so that the right end (i.e., the broken end) of the wire 1 can be lifted to a high place, and then away from the ground, improving safety. When the wire 1 at the right end rises to a certain height, the wire 1 at the right end will lose the squeezing effect on the switch assembly 3, and the switch assembly 3 will change from a closed state to an open state, thereby stopping the driving device 204 from working, that is, the broken end of the wire 1 is lifted and temporarily fixed at a high position, which will not affect the ground.
[0037] like Figure 3 As shown, the lower roller 202 at the bottom can actually support the conductor 1, thereby further improving the stability of the conductor 1. However, during actual use, the conductor 1 will be shaken greatly, such as in strong winds, which will affect the strength of the conductor 1. Figure 6 As shown, a bracket 6 can be installed at the top of the inner part of the frame 203 in a vertical elastic sliding manner through a spring, and the upper roller 201 is rotatably installed in the bracket 6.
[0038] It can be understood that the upper roller 201 can always maintain a state of resistance with the conductor 1 under the action of elastic force, and this limiting force is flexible and will not cause hard squeezing effect on the conductor 1; and when the conductor 1 shakes, the upper roller 201 will move up and down accordingly under the action of the spring, thereby effectively absorbing the impact force generated by the shaking of the conductor 1 and ensuring the stability of the conductor 1.
[0039] In this embodiment, Figure 6As shown, the driving device 204 includes a motor 2041, an upper transmission assembly 2042 and a lower transmission assembly 2043. The motor 2041 is installed at the top of the frame 203 and is electrically connected to the switch assembly 3. The upper transmission assembly 2042 is installed on the bracket 6. The output end of the upper transmission assembly 2042 is connected to the upper roller 201, and the input end of the upper transmission assembly 2042 is spline-connected to the output end of the motor 2041; the lower transmission assembly 2043 is installed at the bottom of the frame 203, the output end of the lower transmission assembly 2043 is connected to the lower roller 202, and the input end of the lower transmission assembly 2043 is spline-connected to the upper transmission assembly 2042.
[0040] It is understandable that after the motor 2041 is powered on by the switch assembly 3, the motor 2041 will drive the upper roller 201 to rotate through the upper transmission assembly 2042; and at the same time, the upper transmission assembly 2042 will also act on the lower transmission assembly 2043, thereby causing the lower roller 202 to rotate.
[0041] It should be explained why the upper transmission component 2042 is connected to the output end of the motor 2041 and the lower transmission component 2043 through a spline: because the upper roller 201 is elastically installed and can float to a certain extent in the upper and lower positions, so that the upper transmission component 2042 will also float up and down, and through the spline connection, the transmission can be guaranteed without affecting the floating of the upper roller 201.
[0042] As a further description of the above embodiment: Figure 6 As shown, the upper transmission assembly 2042 includes an upper worm 20421 and an upper worm wheel 20422, the upper worm wheel 20422 is mounted on the rotating shaft of the upper roller 201, the upper worm 20421 is vertically rotatably mounted on the bracket 6 and matched with the upper worm wheel 20422, and the top of the upper worm 20421 is spline-connected with the output end of the motor 2041. The lower transmission assembly 2043 includes a lower worm 20431 and a lower worm wheel 20432, the lower worm wheel 20432 is mounted on the rotating shaft of the lower roller 202, the lower worm 20431 is vertically rotatably mounted on the inner bottom end of the frame 203 and matched with the lower worm wheel 20432, and the top of the lower worm 20431 is spline-connected with the bottom end of the upper worm 20421.
[0043] It is understandable that the upper worm 20421 can move axially (i.e., vertically) under the action of the spline, and the upper worm 20421 can drive the lower worm 20431 to rotate when rotating. The spiral directions of the upper worm 20421 and the lower worm 20431 are opposite; that is, when the upper worm 20421 and the lower worm 20431 rotate in the same direction, the two worm wheels rotate in different directions, thereby realizing the relative rotation between the upper roller 201 and the lower roller 202.
[0044] In one of the embodiments of the present application, Figure 8 As shown, the switch assembly 3 includes a switch body 301 and a baffle 302. The switch body 301 can be installed at the lower end of the (right) side of the frame 203 through a support plate 4 and electrically connected to the winding mechanism 2 (i.e., the motor 2041); the baffle 302 can be installed on the side of the frame 203 by elastic rotation through a torsion spring.
[0045] It is understandable that if Figure 3 As shown, under normal conditions, the baffle 302 is in a horizontal state, that is, the switch body 301 is in an open state. When the wire 1 is broken, the drooping wire 1 will squeeze the baffle 302 to rotate downward, and the baffle 302 will squeeze and trigger the switch body 301, thereby enabling the motor 2041 to be powered on and operated. After the wire 1 is lifted and moved a certain distance, when the wire 1 is separated from the baffle 302, or the pressure of the wire 1 on the baffle 302 is less than the reset force of the torsion spring, the baffle 302 will lose its squeezing effect on the switch body 301, and the switch body 301 will return to the original open state, and then the motor 2041 will be powered off and stop running, and the cooperation between the worm wheel and the worm is self-locking, that is, at this time, the upper roller 201 and the lower roller 202 will remain in the stopped state, thereby limiting and fixing the moved wire 1.
[0046] like Figure 5 As shown, after the right end (i.e., the broken end) of the wire 1 is lifted, the moved part of the wire 1 will be accumulated at the left side of the winding mechanism 2. Since the wire 1 has a certain weight, and the longer the length of the wire 1 at the left side is, the greater its corresponding weight is. In addition, the upper roller 201 is flexibly installed, so if the force acting on the wire 1 on the left side is greater than the limiting force of the upper roller 201 and the lower roller 202 on the wire 1, the right end of the wire 1 will be separated from the two rollers, and the lifted wire 1 will fall to the ground again.
[0047] Therefore, in order to solve the above technical problems, one of the embodiments of the present application is as follows: Figure 4 and Fig. 9 As shown, the overhead line intelligent monitoring device also includes a storage component 5 and a limit component 8. The storage component 5 is elastically and movably arranged at the bottom end of the frame 203. The limit component 8 is arranged at the bottom end of the frame 203 and is connected to the baffle 302 through the guide structure 7.
[0048] It is understandable that under normal conditions, Fig. 9As shown, the storage member 5 can be locked and retracted at the bottom of the frame 203 under the action of the stopper 8; that is, when the storage member 5 is not in use, it can be folded and retracted at the bottom of the frame 203, thereby protecting the storage member 5. When the wire 1 is broken, the rotation of the baffle 302 can act on the stopper 8 through the guide structure 7, and then the stopper 8 can release the lock on the storage member 5, and the storage member 5 can be unfolded under the action of elastic force, and the unfolded storage member 5 can collect and support the lifted wire 1; Figure 5 As shown in (b), the storage member 5 can collect the wire 1 after being moved to the left side of the winding mechanism 2, so that no matter whether the wire 1 is separated from between the two rollers, the wire 1 will not fall to the ground again, further improving safety.
[0049] Specifically, Figure 4 As shown, the storage member 5 includes a storage rack 501 and a flexible bag 502. The storage rack 501 can be elastically rotated and installed on the bottom (left) side of the frame 203 through a torsion spring, and the flexible bag 502 is installed on the storage rack 501; the flexible bag 502, as the name implies, is a flexible bag body or bag body that can be retracted, such as a net bag or a cloth bag; of course, for the sake of aesthetics and orderliness after folding, a plurality of folding parts can be provided on the outside of the flexible bag 502, and the flexible bag 502 can be stored more compactly and orderly at the bottom of the frame 203 under the action of the folding parts. The limiter 8 is horizontally slidably arranged at the bottom of the frame 203.
[0050] like Fig. 9 As shown, in a normal state, the flexible pocket 502 is retracted at the top of the storage rack 501, and the storage rack 501 rotates to fit and store at the bottom of the frame 203 (the torsion spring is in a deformation energy storage state at this time), and the limiter 8 abuts against the bottom of the storage rack 501, so that the storage rack 501 remains locked. When the wire 1 breaks, the baffle 302 will rotate and slide the limiter 8 through the guide structure 7 until the limiter 8 and the storage rack 501 are staggered and away from each other, and then the storage rack 501 will unfold under the action of the elastic force (as shown in FIG. Figure 4 As shown), the wire 1 that is subsequently moved is collected.
[0051] The present application does not limit the specific structure of the guide structure 7, and a specific embodiment is provided below for reference: like Fig. 9 and Fig.10 As shown, the guide structure 7 includes a guide sleeve 701, a guide block 702 and a (spiral) guide groove 703. The guide sleeve 701 is connected and installed on the limit member 8 and is sleeved on the rotating rod 9 installed on the baffle 302. The guide block 702 is installed on the outside of the rotating rod 9, and the guide groove 703 is arranged inside the guide sleeve 701.
[0052] It is understandable that the rotating rod 9 on the baffle 302 will drive the guide block 702 to rotate, and then the guide block 702 and the guide groove 703 will be spirally slidably matched, thereby driving the limit member 8 to slide, so as to realize the unlocking process of the retracted storage member 5.
[0053] Based on the above embodiment, the following problem may occur during use: after the storage member 5 is unlocked and unfolded, its unfolded state is still maintained by the torsion of the torsion spring, which means that as the length of the collected wires 1 gradually increases, the torsion of the torsion spring must be large enough, which is obviously not in line with the actual application situation. Fig. 9 and Fig.11 As shown, a wedge block 10 can be installed on the bottom side of the frame 203 to slide horizontally through spring elasticity.
[0054] It is understandable that in the initial state, the state of the wedge block 10 is as follows: Fig.12 When the storage rack 501 rotates and abuts against the inclined surface of the wedge block 10, as shown in (c); Fig.12 As shown in (d) in the figure, the wedge block 10 will be squeezed away from the storage rack 501 (the spring is in a state of deformation and energy storage); when the storage rack 501 is fully unfolded and separated from the wedge block 10, that is, the storage rack 501 rotates 180 degrees, the wedge block 10 will be reset and supported against the bottom end of the storage rack 501 under the elastic force of the spring, as shown in FIG. Fig.12 As shown in (e) in the figure, the unfolded storage rack 501 can be locked. That is to say, the unfolded storage rack 501 no longer relies on the torsion support of the torsion spring, but can also be "rigidly" supported by the wedge block 10, so that the wires 1 can be stably collected.
[0055] In order to facilitate the understanding of the overhead line intelligent monitoring device, its working principle is described below: like Figure 1 and Figure 2 As shown, we take the overhead line on the tower as an example. The connection point between conductor 1 and the tower is A. Under normal circumstances, the state of conductor 1 is as follows: Figure 5 When wire 1 is broken, the break of wire 1 is usually located between segments AA, as shown in (a) of FIG. Figure 5 As shown in (b), we assume that the break occurs at B between segments AA, so the wire 1 on the left side of B will sag to the lower left, and the wire 1 on the right side of B will sag to the lower right. We take the sag to the lower left as an example to explain in detail, which mainly goes through four processes: In the first process, the drooping wire 1 will squeeze the baffle 302, and the baffle 302 will rotate downward, and the rotating rod 9 on the baffle 302 will drive the guide block 702 to rotate, and the guide block 702 acts on the guide groove 703 in the guide sleeve 701, so that the guide sleeve 701 can drive the limiter 8 to slide and disengage from the storage member 5; after the baffle 302 rotates downward to the limit position, the baffle 302 will also squeeze the switch body 301. In the second process, the unlocked storage member 5 will rotate 180 degrees counterclockwise under the action of elastic force, and the wedge block 10 will limit the storage member 5 after it is unfolded. Process III: The squeezed switch body 301 will change from the open state to the closed state, so that the motor 2041 starts, and the motor 2041 will drive the upper worm 20421 and the lower worm 20431 to rotate synchronously, and then act on the corresponding lower worm 20431 and the lower worm wheel 20432 to rotate. Since the two pairs of worm wheels have different screwing directions, the upper roller 201 and the lower roller 202 will rotate relatively, that is, the upper roller 201 rotates clockwise and the lower roller 202 rotates counterclockwise. Process IV: The wire 1 will be "pulled" to the left under the driving action of the upper roller 201 and the lower roller 202, so the moving wire 1 will fall downward under the action of gravity, and the net bag can collect the falling wire 1.
[0056] Finally, when the right end of the wire 1 (i.e., the broken end) is lifted to the set height, for example, the right end of the wire 1 is about to break away from the baffle 302, that is, the pressure of the wire 1 on the baffle 302 cannot keep the switch body 301 in the closed state, the switch body 301 will be in the open state, and the motor 2041 will be powered off and stop running; the monitoring module 11 will send the broken wire 1 at this position to the control center, and then dispatch relevant staff to carry out maintenance; after the maintenance is completed, the staff will manually reset the storage unit 5.
[0057] Another aspect of the present application provides a method for monitoring overhead lines, based on the above-mentioned intelligent monitoring device for overhead lines, including a method for protecting the conductor 1 from fracture. In this method, the switch assembly 3 is used to drive the winding mechanism 2 to lift the broken end of the conductor 1 away from the ground, and the fault information is sent to the ground through the monitoring module 11. Of course, the monitoring module 11 is also common knowledge to those skilled in the art; for example, an intelligent ball camera pan / tilt head can realize multi-angle monitoring of components such as overhead lines.
[0058] The above describes the basic principles, main features and advantages of the present application.
