Detailed Description

The following detailed description of the present invention is made with reference to the accompanying drawings and specific embodiments:

in the specific embodiment, as shown in fig. 1 and fig. 2, an electric insulation bird-preventing device structurally comprises a base plate 2 fixed to an electric tower pole 1, and a group of insulation bird spikes 4 arranged on the base plate 2 in a radial distribution manner by means of an intermediate connector, and the key points are as follows: the insulating bird thorn 4 comprises a puncture needle 5, a rubber sleeve 6 which is sleeved on the end part of the puncture needle 5 and seals the puncture needle, and a suspension part 12 which is arranged on the end part of the rubber sleeve.

As shown in fig. 3, by improving the traditional bird thorn, the utility model is provided with a layer of sealed rubber sleeve 6 outside the thorn 5. The setting up of rubber sleeve 6 can make the upper portion of insulating bird thorn 4 insulating, avoids the phenomenon of point discharge to produce, and 6 tops of rubber sleeve set up can enough increase the area of 6 tip of rubber sleeve with the integrative piece 12 that dangles of rubber sleeve 6, and further avoid the phenomenon of point discharge to produce, can keep dangling of 4 tip of insulating bird thorn again, increase device prevent the bird area. In addition, the design of the suspension piece 12 can also ensure that the insulating bird spikes 4 keep certain shaking along with wind in a windy weather state, thereby reducing the staying probability of birds around, obviously improving the bird repelling effect and avoiding nesting and nest building of the birds at the position provided with the bird repelling device. The length of the insulating bird spikes 4 can be set to be equal in length or different in length according to needs, and for effective insulation, the suspension piece 12 is made of polymer, such as ethylene propylene rubber, silicon rubber, ABS engineering plastic, polyurethane and the like. In addition, the shape of the overhang 12 may be circular, triangular, or conical, and the like, and the shape of the overhang 12 is set to be circular in this embodiment.

As shown in fig. 1, 2, 4 and 5, in order to further enlarge the bird-proof area of the insulating bird spikes 4, the cover 7 and the bird spike fixing disk 9 are formed in an arc shape, and the through holes 8 of the cover 7 and the mounting holes 10 of the bird spike fixing disk 9 are radially distributed, so that the insulating bird spikes 4 penetrating through the cover 7 are radially distributed, and the distribution area of the insulating bird spikes 4 is enlarged. The upper end face of the bird thorn fixing disc 9 is set to be in a circular arc shape matched with the top face of the cylinder cover 7, the insulating bird thorn 4 is fixed on the mounting hole of the bird thorn fixing disc 9, and the situation that the insulating bird thorn 9 arranged at the edge of the bird thorn fixing disc 9 cannot be completely retracted and the work of maintenance personnel is influenced due to the fact that the stroke of the insulating bird thorn 9 is shortened when the connecting face is a plane is avoided.

Furthermore, in order to conveniently pack up the insulating bird thorn 4 when the maintainer works, the insulating bird thorn 4 penetrates through the barrel cover 7 of the storage barrel 3 and is fixed on the bird thorn fixing disk 9, the bird thorn fixing disk 9 is arranged in a cavity formed by the storage barrel 3, the bottom of the bird thorn fixing disk 9 is connected with the lifting mechanism, and the bird thorn fixing disk 9 is lifted by controlling the lifting mechanism. When the position of the bird thorn fixing disc 9 is enlarged relative to the cylinder cover 7, the lower part of the insulation bird thorn 4 which passes through the through hole 8 of the cylinder cover 7 is gradually collected into the containing cylinder 3, and the insulation bird thorn 4 outside the upper end is collected.

Furthermore, as shown in fig. 2, the lifting mechanism 11 may be selected from various mechanisms, such as a hydraulic cylinder or a ball screw, and the lifting mechanism 11 in this embodiment is a ball screw, and a screw 112 of the ball screw is inserted into the receiving cylinder 3 and is fixedly connected to the bird thorn fixing plate 9; the nut 111 of the ball screw is fixed to the base plate 2 through the through hole a15 in the base plate 2, and the bottom surface of the nut 111 contacts the plate surface of the support plate 13.

Because the bird-proof device cannot be punched and installed on the power tower pole 1, the nut 111 and the screw rod 112 of the ball screw are eccentrically arranged relative to the storage barrel 3 and avoid the power tower pole 1, and a knob (not shown in the drawing of the specification) for manual operation can be fixed at the outer end of the screw rod 112, so that the insulating bird thorn 4 of the bird-proof device can be conveniently folded by rotating the knob when an operator pedals the tower for operation. In order to avoid punching the power tower pole 1, the bird preventing device can be fixed on the power tower pole 1 by adopting a magnetic adsorption or bolt fixing mode. In this embodiment, the supporting plate 13 is provided as two parts, namely a supporting plate a131 and a supporting plate b132, the supporting plate a131 and the supporting plate b132 are both L-shaped, the base plate 2 is respectively fixed to the supporting plate a131 and the supporting plate b132 through the bolts 14, the supporting plate a131 and the supporting plate b132 are connected and fixed through the bolts 14, the power tower pole 1 is clamped and fixed between the base plate 2 and the supporting plate 13 by adopting a clamping and embedding method, and the bird prevention device is fixed on the power tower pole 1, so that the power tower pole 1 is prevented from being perforated. The support plate a131 is provided with a through hole b16 corresponding to the through hole a15 of the base plate 2 and allowing the screw rod 112 to pass therethrough.

Furthermore, in order to conveniently fix the puncture needle 5 on the bird thorn fixing disc 9 and avoid the phenomenon that the puncture needle 5 is drawn out of the rubber sleeve 6 due to the fact that the rubber sleeve 6 is clamped on the cylinder cover 7 when the insulating bird thorn 4 is folded, the length of the rubber sleeve 6 is smaller than that of the puncture needle 5, the lower end of the puncture needle 5 is exposed, and the exposed length of the puncture needle 5 is about one third of that of the insulating bird thorn. In order to conveniently replace the aged rubber sleeve 6 and prolong the service life of the whole bird-preventing device, the connection mode between the puncture needle 5 and the rubber sleeve 6 is set as detachable connection.
