[0002] During the operation and maintenance of substations, it is necessary to prevent and reduce birds from nesting, staying or crossing in the substation area to prevent short-circuit accidents caused by birds and ensure the safe and stable operation of the power grid. Most of the bird repellent devices on the existing market achieve the purpose of repelling birds through bird repellent spikes. In a patent entitled "A Bird Repellent Device for Outdoor Substations" with announcement number CN214677339U, a rotatable bird repellent spike is provided in the above-mentioned bird repellent device for outdoor substations to prevent birds from nesting on the bird repellent spikes. However, it is driven by wind power. When the wind is too small or there is no wind, smaller birds are likely to stand on the bird repellent spikes to defecate, causing damage to the power facilities under the bird repellent spikes. For this reason, we have designed a bird repellent device for substations. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] A bird repellent device for a substation, such as Figure 1 , 23, comprising a base 1, the base 1 is movably provided with a bird-repelling spike 2, the bird-repelling spike 2 comprises a rotating shaft 5, the outer periphery of the rotating shaft 5 is provided with evenly distributed sharp needles 6, the rotating shaft 5 is rotatably mounted on the corresponding mounting seat 4 through a bearing, the outer periphery of the rotating shaft 5 is provided with a bearing coaxial therewith, and a plurality of wind wheels 7 are fixedly mounted on both ends of the rotating shaft 5, in this embodiment, one end of the rotating shaft 5 is provided with four wind wheels 7, the wind wheels 7 are respectively fixedly mounted on the outer periphery of the rotating shaft 5 through a connecting rod, and the four wind wheels 7 are evenly distributed along the axis of the rotating shaft 5. It is characterized in that: the base 1 is provided with a plurality of springs The rod 3 is fixedly mounted on the mounting seat 4. In this embodiment, two spring rods 3 are provided. The fixed ends of the spring rods 3 are respectively fixedly connected to the base 1, and the movable ends of the spring rods 3 are respectively fixedly connected to the mounting seat 4. The outer periphery of the rotating shaft 5 is rotatably mounted with a coaxial gear ring 8 through a one-way bearing. One side of the gear ring 8 is provided with a rack 9 that can mesh with it. When there is no other heavy object on the bird-repelling spike 2, the rack 9 does not mesh with the gear ring 8. The rack 9 is fixedly mounted on the fixed end of the spring rod 3, and the lower end of the rack 9 is fixedly connected to the outer periphery of the fixed end of the corresponding spring rod 3. The utility model has a simple structure and an ingenious design. When a bird falls on the bird-repelling spike 2, under the action of gravity, the gear ring 8 and the rack 9 are driven to move relative to each other, so that the bird-repelling spike 2 rotates to prevent the bird from staying. It can meet actual needs and is suitable for promotion. When the utility model is used, when there is no wind or the wind force is too small, if a bird lands on the bird-repelling spike 2, the bird-repelling spike 2 compresses the spring rod 3 under the action of gravity, so that the gear ring 8 and the rack 9 are meshed, driving the gear ring 8 and the rotating shaft 5 to rotate, thereby driving the bird-repelling spike 2 to rotate, thereby driving the birds that stay there; when the birds are frightened and fly away, the spring rod 3 drives the bird-repelling spike 2 to reset, so that the gear ring 8 is not meshed with the rack 9. At this time, the gear ring 8 cannot drive the rotating shaft 5 to rotate under the action of the one-way bearing, so the existence of several wind wheels 7 will not increase the resistance to the reset of the rotating shaft 5; when there is wind, the wind wheel 7 drives the bird-repelling spike 2 to rotate.

[0017] Specifically, as shown in the figure, the rotating shaft 5 and the mounting seat 4 described in this embodiment can be detachably mounted, and the mounting seat 4 includes a semicircular arc-shaped arc platform 20, and the upper end of the arc platform 20 extends upward along its vertical tangent. When the bearing of the rotating shaft 5 is placed in the arc platform 20, the upper end of the arc platform 20 is higher than the horizontal tangent of the bearing of the rotating shaft 5. A cover plate 21 is rotatably mounted on one side of the upper end of the arc platform 20, and a pressing block 24 is provided on the cover plate 21. A fixing device for fixing the position of the cover plate 21 and the arc platform 20 is provided on the cover plate 21. An arc-shaped groove 22 is provided on the inner circumference of the arc-shaped platform 20, and the outer circumference of the rotating shaft 5 is fixedly installed with a bearing through an annular step block 23. The annular step block 23 is an annular block with a convex cross-section. The curved surfaces with small diameters of the annular step block 23 are respectively fixedly connected to the inner circumferences of the bearings of the rotating shaft 5. Two bearings are fixedly installed on one annular step block 23. The protruding part of the annular step block 23 can be fitted on the arc-shaped groove 22, and the outer circumference of the bearing of the rotating shaft 5 is frictionally contacted with the corresponding inner circumference of the arc-shaped platform 20. During installation, the cover plate 21 is first rotated to the rear side of the arc platform 20 so that the upper side of the arc platform 20 remains open, and then the protruding part of the annular step block 23 is aligned with the arc groove 22 and moved closer to it until the bearing on the outer side of the annular step block 23 abuts against and contacts the inner wall of the arc platform 20. At this time, the rotating shaft 5 and the arc platform 20 are coaxially arranged, and then the cover plate 21 is rotated to the upper side of the arc platform 20, the pressing block 24 is tightly against the outer periphery of the bearing of the rotating shaft 5, and the cover plate 21 is tightened to fix the bearing of the rotating shaft 5; the cooperation between the arc groove 22 and the annular step block 23 can prevent axial movement between the rotating shaft 5 and the mounting seat 4.

[0018] Further, as shown in the figure, the inner periphery of the arc-shaped platform 20 in this embodiment that contacts and cooperates with the bearing of the rotating shaft 5 is fixedly provided with an anti-skid pad 30. The anti-skid pad 30 can increase the friction between the outer periphery of the bearing of the rotating shaft 5 and the inner periphery of the arc-shaped platform 20, and prevent the outer periphery of the bearing of the rotating shaft 5 and the inner periphery of the arc-shaped platform 20 from sliding relative to each other.

[0019] Furthermore, as shown in the figure, the fixing device of this embodiment includes a screw 40, and corresponding thread grooves 41 are respectively provided on the cover plate 21 and the arc-shaped platform 20, and the screw 40 is threadedly mounted in the corresponding thread grooves 41. When the cover plate 21 is rotated to abut against the upper side of the arc-shaped platform 20, the position of the cover plate 21 and the arc-shaped platform 20 is fixed by screwing the same screw 40 into the thread grooves 41 on the cover plate 21 and the arc-shaped platform 20.

[0020] Furthermore, as shown in the figure, the cover plate 21 of this embodiment is provided with a plurality of spikes 50. The presence of the spikes 50 can prevent birds from standing on the cover plate 21.

[0021] Furthermore, as shown in the figure, the interior of the rotating shaft 5 described in this embodiment is hollow, and through holes 61 are respectively provided at both ends of the rotating shaft 5. The through holes 61 connect the interior of the rotating shaft 5 with the outside world. The diameter of the through holes 61 is smaller than the diameter of the inner wall of the rotating shaft 5. Slide rods 62 are respectively slidably installed in the through holes 61. The inner ends of the slide rods 62 are respectively fixedly installed with stoppers 63. The stoppers 63 are elastically connected to the inner wall of the rotating shaft 5 through springs 64. The springs 64 are sleeved on the outer periphery of the slide rods 62. One end of the spring 64 is fixedly connected to the corresponding stopper 63, and the other end of the spring 64 is fixedly connected to the inner walls at both ends of the rotating shaft 5. The outer ends of the slide rods 62 are respectively fixedly installed with shift blocks 60, and the diameter of the shift blocks 60 is larger than the diameter of the outer wall of the rotating shaft 5. The shifting block 60 can prevent the slide bar 62 from being completely retracted into the rotating shaft 5, and at the same time, it is more convenient to pull out the slide bar 62, and the stopper 63 can prevent the slide bar 62 from being separated from the rotating shaft 5. When in use, it is only necessary to shift the shifting block 60 by hand, so that the shifting block 60 drives the slide bar 62 to slide outward along the inner wall of the through hole 61. At this time, the slide bar 62 is held by hand to facilitate the grasping of the bird-repelling spike 2, thereby removing the bird-repelling spike 2 from the mounting seat 4. When the slide bar 62 is not held by hand, the slide bar 62 enters the rotating shaft 5 under the action of the spring 64, which saves more space.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
