Description

Technical Field

[0001] The invention relates to the technical field of electric power inspection, in particular to an overhead line automatic patrol maintenance robot driven by wind energy. Background Art

[0002] Currently, overhead lines are affected by the natural environment, and there are condensation and ice, snow accumulation and bird droppings corrosion, which are destructive to overhead lines. Severe cases can cause line breakage and large-scale power outages. The existing means are to manually break ice or clear debris on the line after the hidden danger occurs. The disadvantage is that daily maintenance requires personnel to observe on-site to confirm the existence of hidden dangers and deal with them. The conductors cannot be maintained in real time, and if there is too much ice or debris on the overhead transmission lines, once the cables are broken, it will directly affect the safety and reliability of the power grid and the economic benefits of the power companies, affecting the normal operation of the power grid.

[0003] Therefore, how to develop a device that can automatically clean ice and dirt on overhead transmission lines for a long time has become a technical problem that needs to be solved urgently by people in this field. Summary of the invention

The robot is driven only by wind power to cruise back and forth on overhead power transmission cables, effectively and in real time removing ice and dirt on the cables, which can greatly reduce the probability of cable failure and improve the reliability of power grid operation.

[0011] The present invention discloses a wind-powered automatic cruise maintenance robot for overhead lines, in which a machine body provides the main body support for the entire robot on the overhead power transmission cable, wherein the power impeller on the machine body is used to convert wind energy into mechanical kinetic energy for the rotation of the gear ring; the mechanical kinetic energy is transmitted to the planetary gear set, and as the bevel gear rotates in contact with the outer skin of the wire, the entire robot is provided with forward and backward power.

[0012] The present invention provides a wind-powered automatic cruising maintenance robot for overhead lines, wherein the clutch reversing unit is used to adjust the meshing connection relationship between multiple planetary gear sets and the gear rings of multiple power fan wheels. When the robot moves forward to the pole at the end of the overhead power transmission line, the impact reversing plate contacts the pole and applies axial limitation to the striker, and as the robot moves forward, an axial relative displacement occurs between the striker and the striker, thereby disconnecting the meshing connection relationship between the planetary gear set and the gear ring in the forward direction, while the planetary gear set and the gear ring in the backward direction are meshed and connected, and the entire robot performs a backward movement.

DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings. It should be noted that the embodiments are illustrative, not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0021] A wind-powered automatic cruising maintenance robot for overhead lines comprises a body 6 of a shuttle-shaped structure and axially slidingly sleeved on an overhead transmission line 1; the body is open at both axial ends and is provided with a cleaning unit, a clutch reversing unit is axially sliding and penetratingly connected on the body, and a plurality of power impellers 4 are coaxially rotating and axially limitedly connected on the body; the two ends of the clutch reversing unit axially slide out of the front and rear end surfaces of the body in the direction of travel, and a plurality of planetary gear sets 5 sleeved on the overhead transmission line and clutch-connected to the power impellers are fixedly supported in the middle of the clutch reversing unit.

[0022] Preferably, the clutch reversing unit includes a plurality of strikers 3, wherein the plurality of strikers are axially slidable and penetrated and connected to the machine body, and both ends of the plurality of strikers are fitted with a strike reversing plate 2; the strike reversing plate is coaxially slidably mounted on the overhead transmission line.

[0023] Preferably, the power impeller includes an inner ring seat 16, blades 15 and an outer shell 14 which are fixed and coaxially mounted in sequence from the inside to the outside, wherein a gear ring 10 is circumferentially formed on the inner circumference of the inner ring seat, the inner ring seat separates the machine body, and the two axial end faces of the inner ring seat are circumferentially rotatable and axially limitedly connected to the separation surface of the machine body; the helical gear planetary gear set is clutched and meshed.

[0024] Preferably, the planetary gear set includes a support column 11 with a triangular cross-section, which is axially slidably mounted on the overhead transmission line, and a plurality of helical gears 12 are rotatably embedded on the outer wall of the support column, and the outer wall of the support column is fixedly connected to the striker of the clutch reversing unit; the outer periphery of the helical gear is clamped and fitted with the outer skin of the wire of the overhead transmission line, and the gear shaft of the helical gear axially extends out of an axial end face of the support column and is coaxially fixed with a planetary gear 13; the planetary gear is clutched and meshed with the gear ring of the inner ring seat of the power fan wheel.

[0025] Preferably, the cleaning unit includes an ice-breaking shovel 9, an ice-compressing gear 8 and a cleaning brush 7, wherein the ice-breaking shovel and the cleaning brush are fixedly mounted on the circumferential inner wall at the openings at both ends of the body, and the ice-compressing gear is rotatably embedded in the circumferential inner wall at the openings at both ends of the body through a gear shaft.

[0026] In addition, in the present invention, preferably, the circumferentially rotating and axially limited connection method of the two axial end faces of the inner ring seat of the power impeller and the two partition surfaces of the body adopts mature technical means in the prior art.

[0027] In addition, the present invention is preferably provided with two power impellers with opposite impeller tilt directions, that is, the robot is subjected to the following Figure 2 When the wind blows from right to left as shown, the two power fan wheels rotate in opposite directions; however, it should be noted that the helical gears coaxially fixed to the planetary gears meshing with the two power fan wheels through the gear shaft have the same helical grain. When the robot is blown by the wind and causes the power fan wheels to rotate, the rotation directions of the two power fan wheels remain unchanged and are opposite to each other. By adjusting a planetary gear set to mesh with a power fan wheel through the clutch reversing unit, the robot can be moved unidirectionally on the overhead transmission line. When the robot travels to the extreme position, the clutch reversing unit adjusts another planetary gear set to mesh with another power fan wheel. At this time, although the rotation directions of the two power fan wheels remain unchanged due to the wind direction, since the two power fan wheels rotate in opposite directions, even if the helical gear grains are the same, the helical gears of the two sets of planetary gear sets rotate in opposite directions, thereby driving the entire robot to move in the opposite direction on the overhead transmission line.

[0028] In addition, the present invention is preferred. Due to the existence of relative forces, the body of the present invention moves axially under the rotation of the planetary gear set, but the body will also perform a small rotation with the overhead power transmission cable as the axis. During the rotation, it will provide circumferential rotation and axial sliding force on the cable for the cleaning brush, ice-pressing gear and ice-breaking shovel, thereby realizing the function of clearing debris on the cable.

[0029] Finally, all the parts not described in the present invention adopt mature products and mature technical means in the prior art.

[0030] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
