Embodiment 1

[0072] figure 1 shows a schematic diagram of a pruning device according to one embodiment of the invention; figure 2 A schematic diagram of a pruning device without a drone according to an embodiment of the present invention is shown.

[0073] Such as figure 1 and figure 2 As shown, the present embodiment provides a pruning device for super-high branches below the power transmission line. The shearing device includes an unmanned aerial vehicle 300, a support rod 200, and a tree-cutting mechanism 100 arranged in sequence from top to bottom. The tree-cutting mechanism 100 includes :

[0074] The first power source 110 is arranged at the lower end of the support rod 200;

[0075] L-shaped connecting plate 120, one end of the L-shaped connecting plate 120 is connected to the rotating shaft of the first power source 110, and the other end of the L-shaped connecting plate 120 is fixedly connected to the second power source 160;

[0076] The tree felling plate assembly 130 inc...

Embodiment 2

[0084] Figure 3a Shows a front view of a tree felling mechanism according to an embodiment of the present invention; Figure 3b Shows the left side view of the felling mechanism according to one embodiment of the present invention; Figure 4 A schematic diagram of a felling board assembly according to one embodiment of the invention is shown.

[0085] Such as Figure 3a , Figure 3b and Figure 4 Shown, on the basis of embodiment 1, felling tree upper plate 131 and felling tree lower plate 132 are polygonal, a driving gear 133 is set at one corner of the polygon, and driven gear 134 is set at other corners of the polygon.

[0086] The driving gear 133 is set at one corner of the polygon, and the driven gear 134 is set at the other corners of the polygon, which can ensure that the working side of the chain saw 140 is located outside the felling board assembly 130, so that the chain saw 140 can cut super high branches.

[0087] In the present embodiment, the upper board 131 ...

Embodiment 3

[0102] Figure 5 A schematic diagram showing a felling board assembly for removing the upper board for felling trees according to an embodiment of the present invention.

[0103] Such as Figure 5 As shown, on the basis of Embodiment 2, a fixed rod 135 is provided between the upper board 131 and the lower board 132 for cutting down trees, the driven gear 134 is covered on the fixed rod 135, and the driven gear 134 and the fixed rod 135 pass through Bearing connection.

[0104] Only the third power source 170 is used to connect the tree-cutting upper plate 131 and the tree-cutting lower plate 132, which may easily cause the falling of the tree-cutting lower plate 132. By setting the fixing rod 135, the tree-cutting upper plate 131 and the tree-cutting lower plate 132 are reinforced. The connection between them improves the working stability of the felling board assembly 130.

[0105] Further, the felling board assembly 130 also includes a U-shaped bar groove 136, which is ar...

Abstract

The invention provides a pruning device for ultrahigh branches below a power transmission line. The pruning device comprises an unmanned aerial vehicle, a supporting rod and a tree felling mechanism which are sequentially arranged from top to bottom, wherein the tree felling mechanism comprises a first power source arranged at the lower end of the supporting rod; one end of an L-shaped connecting plate is connected with a rotating shaft of the first power source, and the other end is fixedly connected with a second power source; a tree felling plate assembly comprises an upper tree felling plate and a lower tree felling plate, a connecting plate is vertically arranged on the upper tree felling plate, a rotating shaft of the second power source is connected with the connecting plate, and a driving gear, a plurality of driven gears and a chain saw winding the driving gear and the driven gears are arranged between the upper tree felling plate and the lower tree felling plate; the working side of the chain saw is located outside the tree felling plate assembly. A third power source penetrates through the upper tree cutting plate and the lower tree cutting plate, and a rotating shaft of the third power source is connected with the upper tree cutting plate and the lower tree cutting plate through bearings and connected with the driving gear. The working danger of workers is reduced, and the pruning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power equipment protection, in particular to a pruning device for superhigh tree branches under power transmission lines. Background technique [0002] The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as a circuit breaker. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. There are more and more faults caused by external force damage to power lines, and the situation is more complicated and widely distributed, including: blasting rocks in mountains can easily damage insulators and wires; Line tripping; large cranes and excavators working in the line protection area sometimes break wires and damage towers; some criminals are driven by economic interests to steal tower materials, pull wires and other power facilities...
