Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electrified railway catenary technology in transportation industry, concretely relates to a bird repelling shoulder frame device for transportation. BACKGROUND

[0002] In the electrified railway transportation system, the catenary is a key component of power supply, and its safe operation is crucial. However, the catenary is plagued by bird damage during operation, which poses a serious threat to the safety of electrified railway transportation. Specifically, the catenary's pillars and shoulder frames, with their moderate height (8-10 meters from the ground), high structural strength, and large contact area, provide an ideal environment for birds to live and nest.

[0003] When birds nest on the catenary shoulder frame, the materials they use (such as bird nests containing metal components) often cause the catenary to short circuit and trip, severely affecting the stability of power supply. In addition, birds' wings may accidentally short-circuit insulating equipment during flight, causing short-circuit accidents and further exacerbating safety hazards. Even worse, bird droppings may fall on electrical equipment (such as disconnectors and insulators), causing equipment flashover and affecting the normal operation of electrical equipment.

[0004] To address this issue, electrified railway maintenance departments have attempted to install various functional bird repelling devices on the shoulder frame structure. However, due to the strong adaptability of birds, these bird repelling devices have not shown significant results. Therefore, we need to address the problem of birds occupying the shoulder frame from the source, i.e., from the perspective of bird bionics, to design a shoulder frame structure that birds cannot stand on and bird nest materials cannot take root.

[0005] In addition, odor-based repelling is also a common method of bird repelling, i.e., applying aromatic and non-toxic drugs to the outer surface of the shoulder frame material to interfere with the birds' sense of smell, thereby making them stay away from the shoulder frame. However, relying solely on odor-based repelling has limited effectiveness, and needs to be combined with other bird repelling methods to achieve better bird repelling results.

[0006] In summary, to effectively solve the problem of birds falling and nesting on the shoulder frame of the railway operation line, avoid various short-circuit trip failures caused by bird damage, improve the safety and reliability of the catenary system, and reduce the maintenance workload, a new type of bird repelling shoulder frame device for transportation is urgently needed. UTILITY MODEL CONTENTS

[0007] To solve the above problems, the utility model provides a bird repelling shoulder frame device for transportation, which solves the problem of birds falling and nesting on the shoulder frame of the railway operation line, effectively avoids various short-circuit trip failures caused by bird damage, improves the safety and reliability of the catenary system, and reduces the maintenance workload.

[0008] The technical solution of the utility model is as follows:

[0009] A bird-repellent shoulder frame device for transportation includes a shoulder frame body, which includes a triangular hollow tube, a pin header, an inverted T-shaped bolt and a nut. The cross-section of the triangular hollow tube is a right-angled triangle with a right-angled side placed horizontally. A plurality of vertical pin headers are evenly distributed at the top angles of the triangular hollow tube. A groove is provided on the horizontal bottom surface of the triangular hollow tube along the length direction. The T-shaped head of the inverted T-shaped bolt is inside the triangular hollow tube, the screw rod of the inverted T-shaped bolt passes through the outside of the triangular hollow tube from the groove, and the nut is connected to the screw rod of the inverted T-shaped bolt.

[0010] The angle between the inclined surface of the triangular hollow tube and the horizontal plane is greater than 45 degrees.

[0011] Internal teeth are provided on both sides of the cut groove. The internal teeth are warped ends provided on the top of the bottom surface of the triangular hollow tube. The bottom of the T-shaped head of the inverted T-shaped bolt is provided in a shape matching the internal teeth.

[0012] The cross-section of the pins is smaller than the area of ​​a bird's foot.

[0013] The spacing between adjacent pin rows is smaller than the outline size of the nesting material.

[0014] A fixed base is fixedly connected to the vertical right-angle surface of the triangular hollow tube, and the fixed base is fixedly connected to the contact network support through a U-shaped clamp.

[0015] After the U-shaped clamp is put on the contact network pillar, it is fixedly connected to the fixed base through an anti-loosening fastening device.

[0016] The anti-loosening fastening device includes a bolt and a spring washer.

[0017] The outer surface of the shoulder frame body is coated with non-toxic medicine with aromatic smell.

The utility model discloses a bird-repellent shoulder rack device for transportation, which effectively prevents birds from landing and nesting: the shoulder rack body adopts a specially designed triangular hollow tube structure, and the angle between its inclined surface and the horizontal plane is greater than 45°, making it difficult for birds to gain a foothold on the shoulder rack, thereby effectively preventing birds from staying and nesting on the shoulder rack; the vertical needles evenly distributed at the top angles of the triangular hollow tubes further increase the difficulty for birds to gain a foothold, and at the same time, the spacing between the needles is smaller than the outline size of the nesting material, making it impossible for the nesting material to take root.

[0021] 2. The bird repelling shoulder frame device for transportation disclosed in the utility model improves the safety and reliability of the catenary system: by preventing birds from nesting on the shoulder frame, the catenary short-circuit tripping accident caused by bird nest materials (such as bird nests containing metal components) is avoided, thereby improving the operation stability and safety of the catenary system; the safety hazards such as equipment flashover caused by the accidental short-circuit of bird wing insulation equipment and the falling of bird droppings on electrical equipment are reduced, and the reliability of the catenary system is further improved.

[0022] 3. The bird repelling shoulder frame device for transportation disclosed in the utility model enhances the bird repelling effect: the shoulder frame body is coated with a non-toxic drug with a fragrant smell on the outer surface, the taste of birds is further interfered by the smell repelling mode, so that the birds are kept away from the shoulder frame, and the bird repelling effect is enhanced.

[0023] 4. The bird repelling shoulder frame device for transportation disclosed in the utility model is highly adaptable: the shoulder frame body is made of carbon structural steel or long fiber composite material, has good mechanical properties and corrosion resistance, and can adapt to the use requirements under different environments and climate conditions; the design of the row of needles and the cutting groove and other structures considers the bionics characteristics of birds, so that the shoulder frame device has stronger pertinence and adaptability in preventing birds from standing and nesting.
