[0002] In rural areas, for safety and convenient power use, distribution transformers are generally arranged in locations with fewer people in the village and are installed on poles away from the ground to reduce the probability of accidental contact by humans and livestock. However, there are still many accidents where children get electrocuted by climbing poles, and there are also many birds and beasts in rural areas that build nests on distribution transformers, which may even cause short circuits in severe cases.

[0003] Therefore, in view of the above deficiencies, a protection structure for an outdoor distribution transformer is needed. Summary of the Utility Model

Specific implementation manners

[0023] 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.

[0024] An outdoor distribution transformer protection structure, combined with Figure 1 , Figure 2 , including a collar 1, a crossbeam 2, a side inclined beam 3, a straight inclined beam 4, a grid frame 5 and a bird repellent 8, the collar 1 is fixedly connected to two poles 6 on which a transformer 7 is installed, and the crossbeam 2 is horizontally fixedly connected to the collar 1 between the two poles 6. The grid frame 5 is fixedly connected to the pole 6 below the transformer 7, the side inclined beam 3 and the straight inclined beam 4 are both inclined in length direction, the bottom of the side inclined beam 3 is fixedly connected to the collar 1 and the top of the side inclined beam 3 is fixedly connected to the bottom of the grid frame 5, the bottom of the straight inclined beam 4 is fixedly connected to the crossbeam 2 and the top of the straight inclined beam 4 is fixedly connected to the bottom of the front and rear ends of the grid frame 5. Four rotating bird repellents 8 are plugged into the four corners of the grid frame 5.

[0025] Combination Figure 1 , Figure 2 , the collar 1 is preferably a metal semicircular ring structure, which is fixed to the pole 6 by a bolt pair to prevent slipping. The cross beam 2, the side inclined beam 3, the main inclined beam 4 and the grid frame 5 are all made of epoxy resin rods. If the grid frame 5 is far away from the transformer 7, metal rods can be used to further improve the rigidity and increase the anti-deformation ability. The grid frame 5 is formed by a plurality of non-metallic pipes arranged in a tic-tac-toe shape and fixedly connected at intervals up and down, preferably tied with steel wire or fixed with special glue. The outer diameter of the grid frame 5 is larger than the outer diameter of the transformer 7. Even if a child climbs from the bottom to the top, due to the large-scale obstruction of the grid frame 5 and the small gap between each rod, there is no fulcrum, and the grid frame 5 and the transformer 7 are preferably at a certain distance, so the child can be prevented from electric shock to a large extent. At the same time, the larger grid frame 5 can provide a larger activity space for maintenance personnel, and the grid frame 5 is not easy to be electrically inductive and conductive, and has better safety. A plurality of main beams 31 are fixedly connected to the middle of the bottom end of the grid frame 5 . The main beams 31 abut against the electric poles 6 and the side inclined beams 3 are fixedly connected to the main beams 31 to increase the contact surface between the grid frame 5 and the electric poles 6 and improve the connection stability of the grid frame 5 .

[0026] Combination Figure 1 , Figure 4, the bird repeller 8 includes a base 81, a vertical rod 82 and fan blades 83. The base 81 is a strip-shaped structure with a U-shaped cross-section. The open end of the base 81 is sleeved outside a non-metallic pipe of the grid frame 5 and extends out of the bottom of the grid frame 5. The vertical rod 82 is fixedly connected to the top of the base 81. Three hemispherical fan blades 83 are rotatably connected to the top of the vertical rod 82. The rotation radius of the fan blades 83 is greater than one-fourth of the length of the grid frame 5. The blowing of the wind can cause the fan blades 83 to rotate. The large-range rotation of the fan blades 83 can prevent birds and beasts from landing on the grid frame 5, and thus can avoid birds and beasts building nests on the grid frame 5. A circular plane mirror is fixedly connected inside the fan blade 83 to reflect sunlight, which can stimulate the surrounding flying birds and beasts, making them not fall towards the transformer 7, and thus achieving the purpose of preventing birds and beasts from building nests on the transformer 7 and on the electric pole 6. A quadrangular pyramid-shaped prism 87 is fixedly connected to the top of the vertical rod 82. Plane mirrors are provided on all four faces of the prism 87. The setting of the prism can reflect sunlight at multiple angles in a windless environment, stimulate the falling flight of birds and beasts, and reduce the probability of them landing on the grid frame 5.

[0027] Combined with Figure 2 , Figure 3 , two connecting rods 85 are inserted into the open end of the base 81. The connecting rods 85 are in contact with the grid frame 5. The axes of the two connecting rods 85 are not on the same horizontal plane, but the base 81 is skewed by no more than 1°. This facilitates maintenance personnel to release the limit of the grid frame 5 members by the connecting rods 85 and the base 81 by shaking the vertical rod 82, and is convenient for pulling out the connecting rods 85, and then removing the bird repeller 8 so as not to affect the activity space during maintenance. At the same time, it is convenient for installation. Moreover, the connecting rods 85 are relatively long and are not easily separated from the base 81 even under the shaking of strong winds. One end of the connecting rod 85 extends outside the grid frame 5 and is fixedly connected with a cylindrical wide head 86. The outer diameter of the wide head 86 is greater than the outer diameter of the connecting rod 85. The setting of the wide head 86 is convenient for holding by hand and is convenient for pulling out or pushing in the connecting rod 85.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
