Description

Technical Field

[0001] The invention belongs to the field of electric power towers, and in particular relates to an electric power tower monitoring system and a monitoring method. Background Art

[0002] With the development of the national economy, the coverage area of ​​power and communication networks is getting wider and wider, and a large number of iron towers are used in power transmission lines and communication lines, such as high-voltage transmission line towers, communication base station towers, etc. Iron towers play an important role in the coverage of power transmission lines as bridges.

[0003] Some power towers are erected in areas with very different natural environments, and are often damaged by external forces. The main causes of external force damage include: active or passive human damage, sinking or tilting caused by geological reasons. The current measures to deal with external force damage are mainly video monitoring. In traditional technology, drones are usually used for patrol or fixed-point cameras for monitoring power towers. Drone inspections rely on the technical operation of drone professionals, which is also very expensive and cannot achieve all-weather monitoring without blind spots. Fixed cameras are generally unable to take into account the overall situation with a single camera, and there are monitoring blind spots. Multiple monitoring devices are required to cover the entire tower, which greatly increases the monitoring cost. At the same time, since the monitoring system usually needs to be arranged at a high altitude to monitor the power tower from top to bottom, the jitter problem of the monitoring system caused by factors such as high wind volume at high altitudes has a serious adverse effect on the clarity and accuracy of the monitoring camera images. Summary of the invention

[0004] The present invention provides a power tower monitoring system and a power tower monitoring method to solve at least one of the above technical problems.

[0007] The power tower monitoring system of the present invention also includes the following additional technical features:

[0008] The rack is arranged at the top of the track to enable the moving seat to move above the track. A load-bearing roller is installed at the bottom of the moving seat. The load-bearing roller carries the moving seat and rolls along the top surface of the track when the driving member drives the gear to engage with the rack for transmission.

[0009] The gear is arranged at the center of the moving seat, and at least four load-bearing rollers are provided, and the four load-bearing rollers are symmetrically distributed on both sides of the gear.

[0010] A shock absorbing member is arranged between the load-bearing roller and the moving seat.

[0011] The cross section of the track along the vertical direction is in a T-shaped structure, and the moving seat is provided with a T-shaped slot adapted to the track.

[0012] Guide wheels are installed on the side and / or bottom of the T-slot, and the guide wheels roll along the track when the moving seat moves relative to the track.

[0013] The track is configured as a closed structure formed by splicing a straight track and an arc track, and two adjacent straight tracks are arranged at an angle and connected by the arc track; the power tower monitoring system also includes a supporting structure that supports the track at a preset height, the supporting structure includes an arc support frame adapted to the arc track and a connecting component connecting the arc support frame and the main material, the arc track is integrally formed at the top of the arc support frame, and an extension line of a line connecting any point on the arc support frame and its corresponding center of curvature passes through the main material of the power tower, the connecting component includes a first clamping plate and a second clamping plate, the first clamping plate is located on a side of the main material close to the arc support frame and is fixedly connected to the arc support frame, the structure of the first clamping plate is consistent with the surface of the inner concave side of the arc support frame, the second clamping plate is located on a side of the main material away from the arc support frame and is detachably connected to the first clamping plate, so that the first clamping plate and the second clamping plate are clamped and fixed on the main material.

[0014] A conductive rail adapted to the extension direction of the track is arranged below the track. The moving component also includes a busbar, one end of which is connected to the moving seat and the other end is in contact with the conductive rail. The busbar always maintains contact with the conductive rail during the movement of the moving seat.

[0015] The moving seat has an initial position on the track, and is provided with a position detection unit. When the moving seat is located at the initial position, the monitoring system further comprises a target detection unit, and the position detection unit receives a signal from the target detection unit and executes a data clearing procedure.

[0016] A monitoring method for an electric tower is also provided, which adopts the electric tower monitoring system as described above, and is characterized in that a control unit is used to control the moving position of the movable seat on the track and the operating state of the camera unit; a camera target on the electric tower is determined; an initial position of the movable seat and a monitoring position corresponding to the camera target are preset on the track, and position data of the initial position and the monitoring position are pre-stored in the control unit so that the control unit can control the movable seat to move back and forth between the initial position and the monitoring position, and the horizontal coordinate data, vertical coordinate data and focal length data of the camera unit in the state of monitoring the camera target at the monitoring position are pre-stored in the control unit.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0018] 1. The power tower monitoring system of the present invention is provided with a track surrounding the power tower, and the camera unit is driven to surround the power tower and move to any position of the track by the movement of the mobile component that can move along the track, so that the camera unit is facing the observation point to avoid the tower body blocking the observation point, thereby realizing 360° blind-angle-free monitoring of the power tower by the camera unit. Compared with the monitoring method of fixedly setting multiple camera units in the prior art, the power tower monitoring system of the present invention not only has the advantage of 360° blind-angle-free monitoring, but also only needs to deploy one camera unit to realize all-round monitoring of the power tower, which greatly reduces the economic cost of monitoring; in addition, since the camera unit can move along the track with the mobile component, for different observation points, the camera unit can selectively move to an observation position close to the observation point for monitoring and observation, so that the camera unit can realize clear observation of the observation object without the help of high-power focusing, so the requirements for the camera unit's camera accuracy, focal length, etc. are relatively low, further reducing the economic cost of monitoring. In addition, the track setting not only allows the mobile component to drive the camera unit to move around the power tower, but also improves the wind resistance through the stable and reliable support of the mobile component, so that the camera unit can minimize or avoid shaking in high wind speed and large wind volume environments, thereby making the camera clearer and more accurate, and helping the background operators to clearly and accurately control the detailed position inspection of the power tower. Furthermore, based on the fact that the monitoring system can monitor the power tower 360° without blind spots, it can realize convenient monitoring of some specific positions of the power tower. Specifically, the best position of the mobile component for monitoring a specific position on the track can be found in advance and the coordinate position data of the best position can be recorded in the control unit, and the best shooting angle, focal length and other data of the camera unit at the best position can be recorded. When video monitoring of the specific position is needed, it is only necessary to control the mobile component to automatically move from the initial position to the recorded best position and control the camera unit to adjust to the best shooting angle and focal length data through the control unit program, so that the specific position of the power tower can be monitored by video. Even the monitoring of the specific position can be realized by one-click operation, which greatly improves the convenience of monitoring the specific position. In addition, the movement of the mobile seat is achieved through the meshing cooperation of the gear and the rack, which on the one hand helps to simplify the structural design of the mobile component. The gear structure is simple, which is conducive to assembly and reliable transmission. On the other hand, when the driving part stops driving the gear, the meshing limit of the gear and the rack allows the mobile component to remain strictly fixed relative to the track, which can prevent the mobile component from moving due to external environmental factors such as high-altitude wind when the mobile component stops moving and the camera unit is working. That is, in addition to the function of meshing and cooperating with the gear for transmission, the rack also helps to stabilize the mobile seat, thereby improving the anti-shake effect, thereby improving the camera clarity and accuracy of the camera unit, and improving the monitoring and observation effect.Furthermore, since the outer gear ring of the gear is suspended in the air, the gear does not need to bear the weight of the moving assembly and the camera unit, so that the gear is free from the radial force of the base, thereby reducing the friction between the gear and the rack, thereby reducing the wear of the gear and the rack and increasing the service life of the moving assembly. More importantly, the gear only needs to engage with the rack to provide the driving force for the moving assembly to move forward. Therefore, the gear is basically not affected by the gravity of the moving assembly and the camera unit on the basis of not bearing any weight, thereby avoiding the gravity of the moving assembly and the camera unit affecting the transmission stability of the gear, further helping to improve the anti-shake effect, especially when the camera unit moves with the moving base to shoot long pictures or videos around the power tower, the better anti-shake effect during movement helps to improve the clarity of the captured picture.

[0019] 2. As a preferred embodiment of the present invention, the rack is arranged at the top of the track so that the moving seat can move above the track, and a load-bearing roller is installed at the bottom of the moving seat, and the load-bearing roller carries the moving seat and rolls along the top surface of the track when the driving member drives the gear to mesh with the rack. By arranging the load-bearing roller at the bottom of the moving seat, the gravity of the moving assembly and the camera unit is entirely carried by the load-bearing roller. In addition to bearing the gravity of the moving assembly and the camera unit, the load-bearing roller can also ensure the stability of the moving assembly during movement, so that the movement of the moving assembly on the track is more stable, so as to improve the camera accuracy of the camera unit.

[0020] Furthermore, the gear is arranged at the center of the moving seat, and at least four load-bearing rollers are provided, and the four load-bearing rollers are symmetrically distributed on both sides of the gear. Placing the load-bearing rollers on both sides of the gear helps the load-bearing rollers to evenly bear the gravity of the moving assembly, improve the smoothness of the movement of the moving seat, avoid the tilt of the moving seat caused by a single load-bearing roller or unevenly arranged load-bearing rollers, and provide guarantee for the stable monitoring of the camera unit.

[0021] Furthermore, a shock absorber is provided between the load-bearing roller and the moving seat. Since the gravity of the moving assembly is borne by the load-bearing roller, by providing a shock absorber between the load-bearing roller and the moving seat, the shaking amplitude of the moving seat during movement can be reduced, thereby improving the shooting stability of the camera unit.

[0022] 3. As a preferred embodiment of the present invention, the cross section of the track along the vertical direction is T-shaped, and the moving seat is provided with a T-slot adapted to the track. By providing a T-slot adapted to the track in the moving seat, the track and the moving seat are in T-shaped cooperation, with high firmness, strong limiting ability for the moving seat, good guiding effect, and providing guarantee for the stable and normal operation of the moving assembly and the camera unit.

[0023] Furthermore, guide wheels are installed on the side and / or bottom of the T-slot, and the guide wheels roll along the track when the moving seat moves relative to the track. The guide wheels can provide a guiding function for the moving seat, improve the smoothness of the moving seat moving along the track, and avoid the T-slot and the track from getting stuck.

[0024] 4. As a preferred embodiment of the present invention, the track is configured as a closed structure formed by splicing a straight track and an arc track, and two adjacent straight tracks are arranged at an angle and connected by the arc track; the power tower monitoring system also includes a support structure that supports the track at a preset height, the support structure includes an arc support frame adapted to the arc track and a connecting component connecting the arc support frame and the main material, the arc track is integrally formed on the top of the arc support frame, and an extension line of a line connecting any point on the arc support frame and its corresponding center of curvature passes through the main material of the power tower, the connecting component includes a first clamping plate and a second clamping plate, the first clamping plate is located on a side of the main material close to the arc support frame and is fixedly connected to the arc support frame, the structure of the first clamping plate is consistent with the surface of the inner concave side of the arc support frame, the second clamping plate is located on the side of the main material away from the arc support frame and is detachably connected to the first clamping plate, so that the first clamping plate and the second clamping plate are clamped and fixed on the main material. By setting an arc-shaped support frame and a connecting component that are compatible with the arc-shaped track, the track is connected to the power tower. Compared with the method of connecting a number of suspended support rods between the track and the power tower to carry the track, as the power tower structure is the most stable and the main supporting structure of the power tower, by connecting the arc-shaped support frame to the main material of the power tower, the structural stability of the main material and the reliable connection with the connecting component can be used to increase the stability of the connection between the arc-shaped support frame and the power tower, so that the arc-shaped support frame and the main material basically maintain a relatively fixed state, greatly reducing the influence of external factors such as wind on the track. The installation stability of the arc-shaped support frame also ensures the stability of the track thereon, and then ensures the stability of the moving components and the camera unit when they are stationary or moving on the track, and prevents the camera unit from shaking as much as possible, thereby improving the shooting accuracy of the camera unit and improving the clarity of the camera image; in addition, the main material is usually preferably angle steel or round steel. In terms of the implementation method, the arc-shaped support frame is set to have an extension line of a line connecting any point on it and its corresponding center of curvature pass through the main material of the power tower, so that the opening direction of the concave side of the arc-shaped support frame is opposite to the position of the main material, so that the arc-shaped support frame and the main material have a high fit and wrapping property. After the arc-shaped support frame is fixed on the main material by the connecting assembly, the force is evenly applied to each part, which reduces stress concentration and reduces the pressure that causes the main material to tilt away from the preset installation angle. At the same time, the first splint serves as an intermediate component located between the arc-shaped support frame and the main material. The structure of the first splint matches the surface of the concave side of the arc-shaped support frame, so that the first splint can be regarded as a whole with the arc-shaped support frame. The first splint and the arc-shaped support frame together wrap and fit the main material, ensuring that the force is evenly applied to each part of the arc-shaped support frame, reducing stress concentration and reducing the pressure that causes the main material to tilt away from the preset installation angle. At the same time, the installation stability of the arc-shaped support frame is guaranteed, which is beneficial to the stable and clear monitoring of the camera unit.

[0025] 5. As a preferred embodiment of the present invention, a conductive rail adapted to the extension direction of the track is arranged below the track, and the mobile component also includes a busbar, one end of which is connected to the mobile seat, and the other end is in contact with the conductive rail, and the busbar always maintains contact with the conductive rail during the movement of the mobile seat. By providing the conductive rail and the busbar, the camera unit and the mobile component are always in an electrically connected state. Compared with the traditional cable or wire charging method, the charging method of the conductive rail and the busbar can effectively avoid the phenomenon of wire winding and tangling, so that the monitoring system can move along the track indefinitely.

[0048] like Figure 1-Figure 7 As shown, a power tower monitoring system includes: a camera unit 1 for monitoring a power tower 8; a track 2, which is arranged as a closed structure around the power tower 8; a moving component 3, including a moving seat 31, on which the camera unit 1 is installed, and the moving seat 31 can move along the track 2 to drive the camera unit 1 to move to any position of the track 2.

[0049] The power tower monitoring system of the present invention is provided with a track 2 surrounding the power tower 8, and the mobile component 3 that can move along the track 2 moves along the track 2 to drive the camera unit 1 to surround the power tower 8 and move to any position of the track 2, so that the camera unit 1 is facing the observation point to avoid the tower body from blocking the observation point, thereby realizing 360° blind spot monitoring of the power tower 8 by the camera unit 1. Compared with the monitoring method of fixedly setting multiple camera units 1 in the prior art, the power tower monitoring system of the present invention not only has the advantage of 360° blind spot monitoring, but also only needs to deploy one camera unit 1 to realize all-round monitoring of the power tower 8, which greatly reduces the economic cost of monitoring; in addition, since the camera unit 1 can move along the track 2 with the mobile component 3, for different observation points, the camera unit 1 can selectively move to an observation position close to the observation point for monitoring and observation, so that the camera unit 1 can realize clear observation of the observation object without the help of high-power focusing, so the requirements for the camera accuracy and focal length of the camera unit 1 are relatively low, further reducing the economic cost of monitoring.

[0050] In addition, the setting of the track 2 not only allows the mobile component 3 to drive the camera unit 1 to move around the power tower 8, but also improves the wind resistance through the stable and reliable support of the mobile component 3 by the track 2, so that the camera unit 1 can reduce or avoid shaking as much as possible in an environment with high wind speed and large wind volume, thereby making the camera clearer and more accurate, and more helpful for the background operator to clearly and accurately control the detailed position inspection of the power tower 8. Furthermore, on the basis that the monitoring system can monitor the power tower 8 in 360° without blind spots, convenient monitoring can be achieved for some specific positions of the power tower 8. Specifically, the best position for monitoring a specific position of the mobile component 3 on the track 2 can be found in advance and the coordinate position data of the best position can be recorded in the control unit, and the best shooting angle, focal length and other data of the camera unit 1 at the best position for the specific position can be recorded. Therefore, each time the specific position needs to be monitored by video, it is only necessary to control the mobile component 3 to automatically move from the initial position to the recorded best position through the control unit program and control the camera unit 1 to adjust to the best shooting angle and focal length data, so that the specific position of the power tower 8 can be monitored by video. Even the monitoring of the specific position can be realized by one-click operation, which greatly improves the convenience of monitoring the specific position.

[0051] In addition, the movement of the mobile seat 31 is achieved through the meshing cooperation of the gear 32 and the rack 37. On the one hand, it helps to simplify the structural design of the mobile component 3. The gear 32 has a simple structure, which is conducive to assembly and reliable transmission. On the other hand, when the driving member 36 stops driving the gear 32, the meshing limit of the gear 32 and the rack 37 allows the mobile component 3 to be strictly kept relatively fixed with the track 2, which can prevent the mobile component 3 from moving due to external environmental factors such as high-altitude wind when the mobile component 3 stops moving and the camera unit 1 is working. That is, in addition to the function of meshing and cooperating with the gear 32 for transmission, the rack 37 also helps to stabilize the mobile seat 31, thereby improving the anti-shake effect, thereby improving the camera clarity and accuracy of the camera unit 1, and improving the monitoring and observation effect.

[0052] Furthermore, since the outer gear ring of gear 32 is suspended, gear 32 does not need to support the moving component 3 and the camera unit 1, so that gear 32 is free from the radial force of the base, so as to reduce the friction between gear 32 and rack 37, thereby reducing the wear of gear 32 and rack 37 and improving the service life of the moving component 3. More importantly, gear 32 only needs to engage with rack 37 for transmission to provide driving force for the moving component 3 to move forward. Therefore, gear 32 is basically not affected by the gravity of the moving component 3 and the camera unit 1 without bearing any weight, thereby avoiding the gravity of the moving component 3 and the camera unit 1 affecting the transmission stability of gear 32, which further helps to improve the anti-shake effect, especially when the camera unit 1 moves with the moving base 31 to shoot long pictures or videos around the power tower 8, the better anti-shake effect during movement helps to improve the clarity of the shot picture.

[0053] Preferably, the camera unit 1 can adopt a pan-tilt camera and / or a thermal imaging camera, and the pan-tilt camera and / or the thermal imaging camera lens deflection angle range is positive and negative degrees in the vertical direction and degrees in the horizontal direction, and cooperates with the mobile component 3 that moves around the power tower 8 to further eliminate monitoring blind spots and realize all-round monitoring of the power tower 8 without blind spots.

[0054] Preferably, the horizontal height of the track 2 is located above the middle of the power tower 8 and maintains a sufficient safety distance from the top high-voltage line. On the one hand, it ensures that the track 2 has a sufficient height to prevent human damage, and on the other hand, it retains a sufficient safety height to avoid accidentally touching the high-voltage line when installing the track 2.

[0055] As a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, the rack 37 is arranged at the top of the track 2 so that the moving seat 31 can move above the track 2. The bottom of the moving seat 31 is equipped with a load-bearing roller 33, which carries the moving seat 31 and rolls along the top surface of the track 2 when the driving member 36 drives the gear 32 to mesh with the rack 37. By arranging the load-bearing roller 33 at the bottom of the moving seat 31, the gravity of the moving assembly 3 and the camera unit 1 is all carried by the load-bearing roller 33. In addition to bearing the gravity of the moving assembly 3 and the camera unit 1, the load-bearing roller 33 can also ensure the stability of the moving assembly 3 during movement, so that the movement of the moving assembly 3 on the track 2 is more stable, so as to improve the camera accuracy of the camera unit 1.

[0056] The present invention does not limit the positional relationship between the moving seat 31 and the track 2. It can also be that a groove is set on the side of the track 2, and a movement channel is set in the groove. The moving seat 31 is provided with at least two gears 32 symmetrically distributed on both sides of the track 2. The two gears 32 move in the movement channel to mount the moving seat 31 and move it along the track 2 under the track 2.

[0057] As a preferred embodiment of the present embodiment, the gear 32 is arranged at the center of the moving seat 31, and at least four load-bearing rollers 33 are provided, and the four load-bearing rollers 33 are symmetrically distributed on both sides of the gear 32. The arrangement of the load-bearing rollers 33 on both sides of the gear 32 helps the load-bearing rollers 33 to evenly bear the gravity of the moving assembly 3, improves the smoothness of the movement of the moving seat 31, avoids the tilt of the moving seat 31 caused by a single load-bearing roller 33 or unevenly arranged load-bearing rollers 33, and provides a guarantee for the stable monitoring of the camera unit 1.

[0058] Preferably, if Figure 2 As shown, a shock absorbing member 4 is provided between the load-bearing roller 33 and the moving seat 31. Since the gravity of the moving assembly 3 is borne by the load-bearing roller 33, by providing the shock absorbing member 4 between the load-bearing roller 33 and the moving seat 31, the shaking amplitude of the moving seat 31 during movement can be reduced, thereby improving the shooting stability of the camera unit 1.

[0059] As a preferred embodiment of the present invention, Figure 1 , Figure 2 As shown, the cross section of the track 2 along the vertical direction is a T-shaped structure, and the moving seat 31 is provided with a T-shaped slot adapted to the track 2. By providing a T-shaped slot adapted to the track 2 in the moving seat 31, the track 2 and the moving seat 31 are in a T-shaped fit, the fit is strong, the limiting ability of the moving seat 31 is strong, and the guiding effect is good, which provides a guarantee for the stable and normal operation of the moving assembly 3 and the camera unit 1. The present invention does not limit the cross-sectional structural form of the track 2 along the vertical direction, and it can also be an I-shaped structure or other structural forms.

[0060] As a preferred embodiment of this implementation, Figure 1 , Figure 2 As shown, guide wheels 34 are installed on the side and / or bottom of the T-slot, and the guide wheels 34 roll along the track 2 when the moving seat 31 moves relative to the track 2. The guide wheels 34 can provide a guiding function for the moving seat 31, improve the smoothness of the movement of the moving seat 31 along the track 2, and avoid the T-slot and the track 2 from getting stuck during the movement of the moving seat 31.

[0061] As a preferred embodiment of the present invention, Figure 3 , Figure 4As shown, the track 2 is configured as a closed structure formed by splicing a straight track 21 and a curved track 22. Two adjacent straight tracks 21 are arranged at an angle and connected by the curved track 22. The extension line of the line connecting any point on the curved track 22 and the corresponding center of curvature passes through the main material 81 of the power tower 8. The power tower monitoring system also includes a support structure 7 that supports the track 2 at a preset height. The support structure 7 includes an arc-shaped support frame 71 adapted to the arc-shaped track 22 and a connection component 72 connecting the arc-shaped support frame 71 and the main material 81. The arc-shaped track 22 is integrally formed on the top of the arc-shaped support frame 71. The extension line of the line connecting any point on the arc-shaped support frame 71 and its corresponding center of curvature passes through the main material of the power tower 8. The connecting assembly 72 includes a first clamping plate 721 and a second clamping plate 722. The first clamping plate 721 is located on the side of the main material 81 close to the arc-shaped support frame 71 and is fixedly connected to the arc-shaped support frame 71. The structure of the first clamping plate 721 is consistent with the surface of the concave side of the arc-shaped support frame 71. The second clamping plate 722 is located on the side of the main material 81 away from the arc-shaped support frame 71 and is detachably connected to the first clamping plate 721, so that the first clamping plate 721 and the second clamping plate 722 are clamped and fixed on the main material 81.

[0062] By providing an arc-shaped support frame 71 and a connecting assembly 72 adapted to the arc-shaped track 22, the track 2 is connected to the power tower 8. Compared with the method of connecting a number of suspended support rods between the track 2 and the power tower 8 to carry the track 2, under the gravity of the track 2, the support rods are subjected to a huge bending moment. Coupled with the high-altitude wind force, the stability of the support rods is poor, and it is easy to bend downward or shake up and down, causing the track 2 connected to the end of the support rod to deviate from the preset height, thereby causing the camera unit 1 to deviate from the preset position and shake with the track 2, which is not conducive to the stable and clear monitoring of the camera unit 1. In the present application, The main material 81 of the power tower 8 is the most stable structure and is the main supporting structure of the power tower 8. By connecting the arc support frame 71 to the main material 81 of the power tower 8, the structural stability of the main material 81 and the reliable connection with the connecting component 72 can be used to increase the stability of the connection between the arc support frame 71 and the power tower 8, so that the arc support frame 71 and the main material 81 basically maintain a relatively fixed state, greatly reducing the influence of external wind and other factors on the track 2. The installation stability of the arc support frame 71 also ensures the stability of the track 2 thereon, and then ensures the stability of the moving component 3 and the camera unit 1 when they are stationary or moving on the track 2, as much as possible. Prevent the camera unit 1 from shaking, thereby improving the shooting accuracy of the camera unit 1 and improving the clarity of the camera image; in addition, for the preferred embodiment in which the main material 81 is usually made of angle steel or round steel, the arc support frame 71 is set as an extension line of a line connecting any point on it and its corresponding center of curvature passes through the main material 81 of the power tower 8, so that the opening direction of the concave side of the arc support frame 71 is exactly opposite to the position of the main material 81, so that the arc support frame 71 and the main material 81 have a high fit and wrapping property. After the arc support frame 71 is fixed on the main material 81 by the connecting component 72, the force is evenly applied everywhere, which reduces stress concentration and reduces the damage to the main material. 81 is under pressure to tilt away from the preset installation angle; at the same time, the first clamping plate 721 is an intermediate component located between the arc support frame 71 and the main material 81. The structure of the first clamping plate 721 is consistent with the surface of the inner concave side of the arc support frame 71, so that the first clamping plate 721 can be regarded as one with the arc support frame 71. The first clamping plate 721 and the arc support frame 71 together wrap and fit the main material 81, ensuring that the arc support frame 71 is subjected to uniform force at all parts, reducing stress concentration, and reducing the pressure that causes the main material 81 to tilt away from the preset installation angle. At the same time, the installation stability of the arc support frame 71 is ensured, which is beneficial to the stable and clear monitoring of the camera unit 1.

[0063] Specifically, the tower body of the power tower 8 is usually composed of main material 8, diagonal material, horizontal material, transverse material, and auxiliary material. The main material 8 plays a major role in stabilizing and supporting. The main material 8 is usually in the form of angle steel and round steel. Taking angle steel as an example, Figure 3 , Figure 4As shown, the shapes of the first clamping plate 721 and the second clamping plate 722 are adapted to the main material 81, and the first clamping plate 721 and the second clamping plate 722 are respectively arranged on both sides of the main material 81, and the first clamping plate 721 and the second clamping plate 722 can be preferably but not limited to being locked by bolts or other connection methods, so as to fix the arc-shaped support portion fixedly connected to the first clamping plate 721 on the main material 81. The use of bolt connection can improve the installation efficiency of the track 2, facilitate the disassembly and installation of the track 2, and facilitate maintenance and replacement. The power tower 8 has four main materials 81, and preferably four sets of support structures 7 are arranged to firmly connect the track 2 to the power tower 8. The present application does not limit the structural form of the first clamping plate 721 and the second clamping plate 722. Figure 6 , Figure 7 As shown, if the main material 8 is a round steel type, the first clamping plate 721 and the second clamping plate 722 are set to a structural form that is compatible with the main material 8.

[0064] The present invention does not limit the power supply mode of the monitoring system, and it can adopt any one of the following implementation modes:

[0065] Embodiment 1: An electric box is arranged on the power tower 8 or on the ground below the track 2, and the electric box supplies power to the moving component 3 and / or the camera unit 1 through a cable.

[0066] Implementation method 2: Figure 1 , Figure 2 As shown, a conductive rail 5 matching the extension direction of the track 2 is arranged below the track 2, and the moving assembly 3 also includes a busbar 35, one end of the busbar 35 is connected to the moving seat 31, and the other end is in contact with the conductive rail 5. The busbar 35 always keeps in contact with the conductive rail 5 during the movement of the moving seat 31. By providing the conductive rail 5 and the busbar 35, the camera unit 1 and the moving assembly 3 are always in an electrically connected state. Compared with the traditional cable charging method and the first embodiment, the charging method of the conductive rail 5 and the busbar 35 can effectively avoid cable winding, tangling, etc., so that the monitoring system can move along the track 2 indefinitely.

[0067] As a preferred embodiment of the present invention, the moving seat 31 has an initial position on the track 2, and the moving seat 31 is provided with a position detection unit 6. When the moving seat 31 is located at the initial position, the monitoring system further includes a target detection unit, and the position detection unit 6 receives the signal of the target detection unit and executes a data clearing procedure. By setting the cooperation between the position detection unit 6 and the target detection unit, each time the monitoring system completes a cycle, the detection unit clears the data signal to realize the reciprocating monitoring of the monitoring system. Specifically, the target detection unit can be a target sensor, etc., and the position detection unit 6 can be a magnetic part that can cooperate with the target sensor to produce a reaction, etc.

[0068] The present invention also provides a monitoring method for an electric power tower 8, which adopts the electric power tower monitoring system as described above, controls the moving position of a movable seat 31 on a track 2 and controls the operating state of a camera unit 1 through a control unit; determines a camera target on the electric power tower 8; presets an initial position of the movable seat 31 and a monitoring position corresponding to the camera target on the track 2, and pre-stores the position data of the initial position and the monitoring position into the control unit, so that the control unit can control the movable seat 31 to move back and forth between the initial position and the monitoring position, and pre-stores the horizontal coordinate data, vertical coordinate data and focal length data of the camera unit 1 in the state of monitoring the camera target at the monitoring position into the control unit.

[0069] On the basis that the monitoring system can monitor the power tower 8 in 360° without blind spots, convenient monitoring can be achieved for some specific positions of the power tower 8. Specifically, the best position for monitoring a specific position of the mobile component 3 on the track 2 can be found in advance and the coordinate position data of the best position can be recorded in the control unit, and the best shooting angle, focal length and other data of the camera unit 1 at the best position can be recorded. Therefore, each time the specific position needs to be monitored by video, it is only necessary to control the mobile component 3 to automatically move from the initial position to the recorded best position and control the camera unit 1 to adjust to the best shooting angle and focal length data through the control unit program, so that the specific position of the power tower 8 can be monitored by video. Even the monitoring of the specific position can be achieved by one-click operation, which greatly improves the convenience of monitoring the specific position.

[0070] Specifically, the optimal position can be the monitoring position corresponding to the camera target described in the method. After the camera target is determined, the camera unit 1 can be driven to move from the initial position to the monitoring position by manually adjusting the moving component 3 for the first time. The position coordinate information of the initial position and the monitoring position on the track 2 are recorded in the control unit, and the horizontal coordinate data, vertical coordinate data and focal length data of the camera unit 1 at the monitoring position are also recorded in the control unit to determine the optimal shooting angle and focal length. Figure 5 As shown, the dotted frame is the optimal observation position of the lens of the camera unit 1 after adjustment. When the camera unit 1 returns to the initial position and needs to monitor and film the specific monitoring position again, the control unit can retrieve relevant data information with one click to implement the corresponding operation.
