[0002] The protective baffle is a baffle used for protection. Since high-voltage transmission line towers have superior conditions for birds to live in in terms of height and safety, they have gradually become an important place for birds to build nests and activities. As a result, the overturning of bird nests causes line failures, and bird droppings cause insulator flashover obstacles to occur frequently. Therefore, it is necessary to install a bird-proof baffle on the high-voltage transmission tower.

[0003] According to the existing patent publication number: CN218649887U, a retractable protective baffle for bird-repelling equipment includes a protective baffle body, a mounting hole is fixedly provided at the middle of the top of the protective baffle body, an insulating layer is laid on the top of the protective baffle body, and two sliding grooves are fixedly provided inside the protective baffle body. In the utility model, a slidable retractable plate is fixedly provided on both sides of the protective baffle, and the area of ​​the entire protective baffle can be adjusted by adjusting the retractable baffle, but the following defects are exposed during use:

[0004] 1. As described in the above-mentioned reference patent, in order to increase the area of ​​the protective baffle, the area of ​​the entire protective baffle can be adjusted by sliding the telescopic plates on both sides, but each adjustment requires constantly loosening and then tightening the fixing bolts, which makes the operation more cumbersome.

[0005] 2. Usually, only the protective baffles are used to prevent birds, which cannot effectively scare and disturb the birds, resulting in poor bird-repelling effect. Utility Model Content

[0006] The purpose of the utility model is to provide a retractable protective baffle to solve the problems of the existing protective baffle in the use process mentioned in the background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A retractable protective baffle comprises a main protective plate, an upper protective plate and a lower protective plate, a rotating wheel is installed at the middle end of the surface of the main protective plate, and a connecting end of the rotating wheel is connected to a rotating shaft;

[0009] A bevel gear 1, which is mounted at the end of the rotating shaft and located inside the main protective plate;

[0010] A bidirectional screw rod is connected to the inside of the main protection plate through a bearing, and the bidirectional screw rod is meshed with a bevel gear 1 through a bevel gear 2 in the middle;

[0011] A connecting frame mounted on the top of the upper protective plate;

[0012] Wind chimes are equidistantly mounted on the inner side of the connecting frame and the bottom of the lower protective plate.

[0013] Preferably, the upper protective plate and the lower protective plate are meshed with both ends of the bidirectional screw through a centrally fixed center column.

[0014] Preferably, a storage box is symmetrically mounted on the surface of the main protective plate, a box cover is snapped onto the top of the storage box, and a grid plate is arranged on the inner side of the box cover.

[0015] Preferably, mounting parts are symmetrically mounted on the back of the main protective plate, and the mounting parts are L-shaped.

[0016] Preferably, each group of wind chimes are connected by a connecting rope to generate linkage.

[0017] Preferably, the outer circumferences of the upper protective plate and the lower protective plate are both smaller than the inner wall circumference of the main protective plate.

[0018] Preferably, the interiors of the main protective plate, the upper protective plate and the lower protective plate are all hollow, and the connecting frame is U-shaped.

[0019] The embodiment of the utility model provides a retractable protective baffle, which has the following beneficial effects:

[0020] 1. By setting a rotating wheel, a bidirectional screw and a center column, the rotating wheel is rotated to one side, driving the bidirectional screw to rotate and engage with the center column, so that the upper protective plate moves upward and the lower protective plate moves downward, thereby increasing the protection area of ​​the main protective plate. Unlike fixing with fixing bolts, there is no need to constantly loosen and then tighten the fixing bolts, so as to improve the convenience of adjustment.

[0021] 2. By setting up wind chimes, connecting ropes, and storage boxes, the wind chimes will shake under the action of external wind and make pleasant sounds, which will cause discomfort to birds and reduce their stay. At the same time, when the wind chimes shake, they will reflect light to produce a flashing effect, which will drive away birds. In addition, items with special smells, such as chili powder, can be placed in the storage box to further drive away birds. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example: Figure 1-Figure 5 As shown, a retractable protective baffle includes a main protective plate 1, an adjusting component consisting of a rotating wheel 4, a rotating shaft 7, a bevel gear 1 8, a bevel gear 2 9, a bidirectional screw 10 and a center column 14. The mounting member 6 is placed in a suitable position, and then the connecting member is connected to the mounting hole on the surface of the mounting member 6 to fix the main protective plate 1 and the object to be protected. Then, according to actual needs, the rotating wheel 4 can be rotated on both sides to drive the rotating shaft 7 at the connecting end to rotate, and the rotating shaft 7 will drive the bevel gear 1 8 at the end to rotate. The bevel gear 1 8 is meshed with the bevel gear 2 9 during the rotation process, so that the bevel gear 2 9 drives the bidirectional screw 10 to rotate with the bearing on the surface. Since the upper protective plate 2 and the lower protective plate 3 are meshed with the surface of the bidirectional screw 10 through the center column 14, the upper protective plate 2 and the lower protective plate 3 are moved closer to or away from each other as the bidirectional screw 10 rotates, thereby increasing or decreasing the area of ​​the main protective plate 1.

[0032] like Figure 4 and Figure 5As shown, the connecting frame 11 is used to support the wind chimes on the upper protective plate 2. Since the protective baffle is usually installed at a high place, the air flow it is exposed to is more sufficient. The connecting rope 13 connects multiple groups of wind chimes. When affected by the wind, the wind chimes 12 will shake and produce a harsh sound, making birds unwilling to approach or stay in the protected area. At the same time, the wind chimes 12 will reflect light, and the flashing of the wind chimes 12 can attract the attention of birds and drive them away, thereby improving the driving effect.

[0033] like Figure 1 and Figure 6 As shown, the box cover 15 is opened, and items with pungent smells such as chili powder are placed in the storage box 5, and then the box cover 15 is closed, so that the pungent smells of items such as chili powder are emitted into the surrounding air through the mesh plate 16 inside the box cover 15. Since birds are more sensitive to such smells, the smells can be driven away.

[0034] Working principle: Place the mounting part 6 at a suitable position, and then connect the connecting part to the mounting hole on the surface of the mounting part 6 to fix the main protective plate 1 and the object to be protected. Then, according to actual needs, the rotating wheel 4 can be rotated on both sides to drive the rotating shaft 7 at the connecting end to rotate, and the rotating shaft 7 will drive the bevel gear 1 8 at the end to rotate. The bevel gear 1 8 meshes with the bevel gear 2 9 during the rotation process, so that the bevel gear 2 9 drives the bidirectional screw 10 to rotate with the bearing on the surface, so that the upper protective plate 2 and the lower protective plate 3 are close to or closer to each other with the rotation of the bidirectional screw 10. The wind chimes 12 are arranged to be away from each other, thereby increasing or decreasing the area of ​​the main protective plate 1, and putting items with pungent odors such as chili powder into the storage box 5, so that the pungent odors emitted by items such as chili powder can be emitted into the surrounding air through the mesh plate 16 inside the box cover 15, thereby playing a role in driving away birds. At the same time, the wind chimes 12 shake under the action of external wind force and make pleasant sounds, which bring discomfort to birds and reduce the birds' stay. At the same time, when the wind chimes 12 are shaken, they will reflect light to produce a flashing effect, which further drives away birds.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
