Description

Technical Field

[0001] The present invention relates to the technical field of power transmission, and particularly to a flexible anti-falling device for power transmission line inspection. Background Art

[0002] At present, when a power transmission line is in long-term use, in order to avoid line failures, inspection robots are needed to promptly find damaged points. Generally, the inspection robot uses the conductor (ground wire) as its travel track. The power transmission conductor has a certain curvature and will dance under the action of wind. When the inspection robot moves on the dancing conductor, it is easy for the clamping mechanism provided on the power transmission line inspection robot to disengage from the conductor, causing the power transmission line inspection robot to fall rapidly. The distance between the conductor of the high-voltage overhead power transmission line and the ground is generally dozens of meters, and the environment of the power transmission line corridor is harsh and complex. The power transmission line inspection robot will be severely damaged after falling. In addition, the existing power transmission line inspection robots cannot firmly clamp conductors of different diameters, so when inspecting conductors of different diameters, different clamping mechanisms need to be replaced.

[0003] In addition, when the existing anti-falling devices are in use, there are also the following two technical problems:

[0004] (1) The cable between the electric towers needs to be sleeved with a protective sleeve or a support frame. When the existing anti-falling device passes through the support frame, since the existing anti-falling device does not have the function of crossing over, the existing anti-falling device is easily stuck on one side of the support frame, thus affecting the inspection of the inspection robot.

[0005] (2) The existing anti-falling devices for power transmission line inspection robots lack a bird repelling device, cannot effectively reduce the influence of wind on the inspection robot, and cannot avoid the damage caused by various flying birds to the inspection robot.

[0006] Therefore, a flexible anti-falling device for power transmission line inspection is proposed in this solution to solve the technical problems of how to ensure the connection strength between the inspection robot and power transmission lines of different diameters and having the function of short-range crossing over the support frame. Summary of the Invention

[0007] The purpose of the present invention is to provide a flexible anti-falling device for power transmission line inspection, which solves the technical problem of how to ensure the connection strength between the inspection robot and power transmission lines of different diameters, realizes the function of short-range crossing over the support frame or the protective sleeve, helps to repel birds, and achieves the technical effect of multiple functions.

[0008] A flexible anti-falling device for power transmission line inspection, including a horizontally arranged support crossbar, a moving mechanism for reciprocating inspection is movably arranged on the support crossbar, the moving mechanism is movably connected with the power transmission line, the moving mechanism is fixedly connected with the free end of an electric push rod, and the fixed end of the electric push rod is positioned on the support crossbar;

[0010] An inflation component and a bird repelling and buffering structure are arranged on the moving mechanism.

[0011] The moving mechanism includes a fixing plate slidably connected to the support crossbar, two groups of rotation adjustment components respectively arranged on both sides of the fixing plate, and a power driving structure arranged on the rotation adjustment components. The two power driving structures are respectively movably arranged on both sides of the power transmission line, and the reciprocating inspection movement is realized through the friction force between the power driving structure and the power transmission line.

[0012] The rotation adjustment component includes two rotating rods respectively rotatably connected to the fixing plate at one end, a first gear and a second gear respectively coaxially connected to one end of the two rotating rods, and a power motor connected to the first gear or the second gear. The first gear and the second gear are meshed with each other;

[0013] There are two rotation adjustment components and they are respectively arranged on both sides of the fixing plate.

[0014] The power driving structure includes a driving column vertically rotatably connected to the other end of the rotating rod, a micro motor connected to the driving column, an airbag cylinder sleeved outside the driving column, a baffle sleeved on the lower end of the airbag cylinder, and a third gear coaxially and fixedly connected to the top end of the driving column. The adjacent third gears are meshed with each other;

[0015] The driving column is in a shell shape and is communicated with the airbag cylinder on the outside. The top end of the driving column is communicated with one end of an air pipe. The baffle horizontally supports on the bottom side of the power transmission line, and the other end of the air pipe is connected with the inflation component.

[0016] The baffle and the upper third gear are respectively arranged above and below the power transmission line to clamp and limit the power transmission line, so that the power transmission line is limited in the up-down, left-right directions.

[0017] More preferably, in this solution, an inflatable wheel can also be used to replace the airbag cylinder, and the connection strength will be higher. The tire of the inflatable wheel and the airbag cylinder are both made of high-strength rubber material.

[0018] The clamping structure includes vertical rods respectively and fixedly arranged at two ends of the supporting cross bar, a rotating seat rotatably connected to the side of the vertical rod, a telescopic cylinder hinged to one end of the rotating seat, a positioning frame fixedly arranged at the other end of the rotating seat, and an iris mechanism fixedly connected to the positioning frame. The iris mechanism is detachably connected to the power transmission line.

[0019] The fixed end of the telescopic cylinder is rotatably connected to the vertical rod, and the free end of the telescopic cylinder is hinged to the rotating seat.

[0020] The iris mechanism includes a positioning ring, a plurality of adjusting columns vertically and rotatably connected to the positioning ring, a cam plate rotatably connected to one end of the adjusting column, a transmission belt connecting two adjacent adjusting columns, and an adjusting motor connected to one of the adjusting columns.

[0023] Solenoid valves are arranged on the air pipe 1, the air pipe 2, the exhaust pipe, and the air delivery pipe.

[0024] Patterns for increasing friction are arranged on the outer side of the airbag cylinder.

[0025] The beneficial effects of the present invention are as follows:

[0026] (1) In this solution, a rotating adjustment assembly and a power driving structure are designed, and they cooperate with each other to achieve the following technical effects:

[0027] First, by using the rotating adjustment assembly to adjust the rotation angle of the rotating rod, adjacent two power driving structures clamp or separate from the power transmission line. When a protective sleeve or a support frame is arranged on the power transmission line, the power driving structure separates from the power transmission line, achieving the function of the anti-falling device passing over.

[0028] Second, when the two power drive structures come into contact, two adjacent gear threes are meshed and connected to each other, and at the same time, the airbag cylinder is inflated, so that two adjacent airbag cylinders clamp the power transmission line. Under the action of the micro-motor, the airbag cylinder is driven to rotate, and the friction between the outer side of the airbag cylinder and the power transmission line promotes the movement of the entire device, and it is applicable to power transmission lines with different diameters;

[0029] (2) The clamping structure is designed in this solution, and it has the following technical effects:

[0030] First, multiple cam plates clamp the power transmission line, which can increase the positioning connection of the entire device on the power transmission line;

[0031] Second, when the power drive structure is separated from the power transmission line, the two clamping structures are clamped and connected to the power transmission line together, assisting the work of the power drive structure to ensure that the entire device is always connected to the power transmission line;

[0032] Third, in this solution, the existing iris mechanism is improved. The existing five cam plates are changed to four cam plates, and a gap is formed between two of the cam plates, so that the power transmission line can pass through the gap and be clamped between the four cam plates to form a strong clamping force, and it is applicable to power transmission lines with different diameters;

[0033] (3) A bird repelling and buffering structure is provided, and it has the following technical effects:

[0034] First, when encountering strong wind weather, the fan blade drives the propeller and the rotating column to rotate. On the one hand, it has the effect of unloading the wind force to avoid the entire device from being impacted greatly. On the other hand, the rotation of the propeller generates a certain lift force, simulating the working principle of an unmanned aerial vehicle, which helps to avoid the overload of the power transmission line;

[0035] Second, it drives the rotation of the column and the flexible rope, and the rotation of the flexible rope has the effect of repelling birds;

[0036] (4) An inflation assembly is provided, and it has the following technical effects:

[0037] First, the air pump is used to inflate multiple airbag cylinders, promoting the expansion of the airbag cylinders and contacting the power transmission line;

[0038] Second, when the air pump works, it inflates the exhaust pipe, and one end of the exhaust pipe exhausts outward, in the same direction as the wind direction, to ensure the balance of the entire device through the effect of backwash;

[0039] Third, the exhaust process of the exhaust pipe can also achieve the effect of driving away birds. Brief Description of the Drawings

Two adjacent third gears 25 are meshed with each other;

[0060] The driving column 22 is in a shell shape and is communicated with the airbag cylinder 24 on the outside. The top end of the driving column 22 is communicated with one end of an air pipe 26. The retaining piece 23 horizontally supports on the bottom side of the power transmission line 12, and the other end of the air pipe 26 is connected to the inflation assembly 6.

[0061] The clamping structure 11 includes vertical rods 14 respectively and perpendicularly fixed at both ends of the support crossbar 1, a rotating seat 8 rotatably connected to the side of the vertical rod 14, a telescopic cylinder 9 hinged to one end of the rotating seat 8, a positioning frame 10 fixed to the other end of the rotating seat 8, and an iris mechanism fixedly connected to the positioning frame 10.

[0062] The fixed end of the telescopic cylinder 9 is rotatably connected to the vertical rod 14, and the free end of the telescopic cylinder 9 is hinged to the rotating seat 8.

[0063] The iris mechanism includes a positioning ring 111, a plurality of adjusting columns 114 vertically and rotatably connected to the positioning ring 111, a cam plate 112 rotatably connected to one end of the adjusting column 114, a transmission belt 113 connecting two adjacent adjusting columns 114, and an adjusting motor 115 connected to one of the adjusting columns 114. An opening is provided on the outer side of the positioning ring 111, and the width of the opening is greater than the outer diameter of the transmission line 12.

[0065] The inflation assembly 6 includes an air pump 61 fixed to one end of the fixed plate 7, an air pipe 62 connected to one end of the air pump 61, an air pipe 63 connected to the other end of the air pipe 62, and the other end of the air pipe 63 is communicated with the exhaust pipe 64. Solenoid valves are respectively arranged at both ends of the exhaust pipe 64.

[0066] Solenoid valves are arranged on the air pipe 62, the air pipe 63, the exhaust pipe 64, and the air delivery pipe 26.

[0067] The outer side of the airbag cylinder 24 is provided with patterns for increasing friction.

[0068] The specific working process of the present invention:

[0069] During actual use, the power driving structure 2 is adjusted so that two adjacent airbag cylinders 24 on both sides of the transmission line 12 are in contact with each other. When the micro motor 21 is started, the friction between the airbag cylinder 24 and the transmission line 12 drives the entire device to move forward along the transmission line 12. Specifically, when two power driving structures 2 are in contact, two adjacent gear wheels three 25 are meshed and connected, and at the same time, the airbag cylinder 24 is inflated, so that two adjacent airbag cylinders 24 clamp the transmission line 12. Under the action of the micro motor 21, the airbag cylinder 24 is driven to rotate, and the friction between the outer side of the airbag cylinder 24 and the transmission line 12 promotes the movement of the entire device, and it is applicable to transmission lines 12 with different diameters;

[0070] The inflation assembly 6 is provided, and the air pump 61 is used to inflate a plurality of airbag cylinders 24 to promote the expansion of the airbag cylinders 24 and contact the transmission line 12; when the air pump 61 works, the exhaust pipe 64 is inflated, and one end of the exhaust pipe 64 discharges air outward, which is in the same direction as the wind direction, and the balance of the entire device is ensured through the recoil effect; the exhaust process of the exhaust pipe 64 can also be used to drive away birds.

[0071] It should be noted that electromagnetic valve structures are provided on the first trachea 62, the second trachea 63, the exhaust pipe 64, and the air delivery pipe 26 in this solution, and are uniformly adjusted and controlled by the controller according to the actual situation, which will not be elaborated here.

[0072] Meanwhile, in order to increase the connection strength of the entire device on the power transmission line 12, at this time, the telescopic cylinder 9 works to drive the rotating seat 8 to rotate and adjust the angle of the positioning frame 10 so that the clamping structure 11 can clamp the power transmission line 12. Specifically, an opening is provided on the positioning ring 111, and a spacing is provided between two adjacent cam plates 112. In this way, the power transmission line 12 enters the opening and is clamped between multiple cam plates 112. When the entire device moves, as long as the cam plates 112 contact and limit the power transmission line 12. When the device stops, multiple cam plates 112 strongly clamp the power transmission line 12; in this solution, the existing iris mechanism is improved, and the existing five cam plates 112 are changed to four cam plates 112, and a notch is formed between two cam plates 112, so that the power transmission line 12 can pass through the notch and be clamped between the four cam plates 112 to form a strong clamping force and is applicable to power transmission lines 12 with different diameters;

[0073] More preferably, a bayonet is provided at the part where multiple cam plates 112 contact the power transmission line, and the bayonet contacts the power transmission line to form a clamping force on the outer side of the power transmission line to maintain a stable positioning;

[0074] Since there is a spacing between adjacent airbag cylinders 24 and multiple cam plates 112 can rotate, it is applicable to power transmission lines 12 with different outer diameters.

[0075] See Figures 9 - 10 , when a protective sleeve or a support frame 15 needs to be sleeved on the cable between the electric towers, when the anti-falling device passes through the support frame 15, in order to cross it conveniently and quickly; at this time, first move the airbag cylinder 24 to the position of the protective sleeve or the support frame 15, use the two iris mechanisms to clamp and fix the power transmission line 12, and then drive the adjacent two airbag cylinders 24 to separate. At this time, it is necessary to ensure that one of the iris mechanisms is already on the other side of the protective sleeve or the support frame 15. At this time, the electric push rod 13 works to push the moving mechanism towards the direction of the protective sleeve or the support frame 15 and make two adjacent airbag cylinders 24 cross the protective sleeve or the support frame 15. At this time, the adjacent two airbag cylinders 24 contact again and contact the power transmission line 12, and the iris mechanism is released from the power transmission line 12. Under the action of the micro-motor 21, the entire device is driven to move a certain distance again until another adjacent two airbag cylinders 24 approach the protective sleeve or the support frame 15;

[0076] Repeat the above steps, i.e., the two iris mechanisms grip the power transmission line 12 again. Subsequently, the airbag cylinder 24 is released from the power transmission line 12, and the electric push rod 13 continues to work until the other two adjacent airbag cylinders 24 cross the protective sleeve or the support frame 15. When both groups of airbag cylinders 24 have crossed the protective sleeve or the support frame 15, the airbag cylinder 24 contacts the power transmission line 12 again. At this time, the iris mechanism is released from the power transmission line 12 and is on the other side of the protective sleeve or the support frame 15. Subsequently, the entire device moves normally.

[0077] In this solution, a bird repelling and buffering structure 4 is also provided. When encountering strong wind weather, the fan blade 41 drives the propeller 42 and the rotating column 43 to rotate. On the one hand, it has the effect of unloading the wind force to avoid the whole device from being impacted greatly. On the other hand, the rotation of the propeller 42 generates a certain lift force, simulating the working principle of an unmanned aerial vehicle, which helps to avoid the overload of the power transmission line 12; it drives the rotation of the column 44 and the flexible rope 45, and the rotation of the flexible rope 45 plays the role of repelling birds.

[0078] It should be noted that in order to reduce the weight of the whole device, the device is made of lightweight materials as a whole.

[0079] The technical features not described in this invention can be achieved by or adopted from the prior art, and will not be elaborated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the scope of the essence of this invention should also fall within the protection scope of this invention.
