Description

Technical Field

[0001] This utility model relates to a simplified contact wire ratchet novel bird-proof plate, belonging to the field of simplified contact wire for high-speed railways. Background Technology

[0002] Bird damage to high-speed railway overhead contact lines from January to June each year has become a major hidden danger affecting the safety of power supply. Existing bird control measures, mainly relying on odorous bird repellents and windmills, have proven to be very limited in their effectiveness. Simplified overhead contact line equipment, a new type of component recently introduced, is prone to bird nesting due to its platform structure at the ratchet points. During peak bird damage periods, nests are built too quickly, and the daily maintenance windows limit real-time monitoring and removal. In rainy weather, bird nest branches can short-circuit with live equipment, causing power outages and seriously impacting the safety of high-speed trains. Summary of the Invention

[0003] Based on the problems described in the background, the problem to be solved by this utility model is to provide a simplified contact wire ratchet-type bird-proof plate, which is developed using the "isolation principle". It does not change the ratchet structure and can be directly installed using the original 16 bolts of the frame without changing the original equipment structure, thus solving the hidden danger of equipment tripping caused by the extension of branches from bird nests.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a simplified contact wire ratchet bird-proof plate, comprising a fixing plate, fixing bolt holes, fixing elongated holes, a U-shaped bending plate, a blocking plate, and upper fixing bolt holes. The fixing plate is rectangular, with fixing bolt holes at each of the four corners. A fixing elongated hole is provided between every two fixing bolt holes and is located on the long side of the fixing plate. A U-shaped bending plate is vertically connected to one side of the fixing plate, and a blocking plate is vertically installed on the other side of the U-shaped bending plate. The blocking plate is rectangular, and two sets of upper fixing bolt holes are provided at the top of the blocking plate on one side of the U-shaped bending plate.

[0005] Preferably, the fixed plate and the U-shaped bending plate have the same width, and the side of the U-shaped bending plate that connects to the long side of the fixed plate is also connected to one long side of the blocking plate.

[0006] Preferably, the device further includes an extended bending plate, ventilation holes, and rolled edges. The extended bending plate is connected to one side of the U-shaped bending plate connected to the blocking plate and is along the short side of the blocking plate not connected to the U-shaped bending plate. The ventilation holes are long, rounded rectangles. Multiple sets of ventilation holes are provided and are opened on the part of the blocking plate not connected to the U-shaped bending plate. The rolled edges are connected to the two sides of the blocking plate located on the U-shaped bending plate.

[0007] Preferably, the fixing plate and the U-shaped bending plate are on the same plane, and the plane area of ​​the fixing plate is smaller than that of the U-shaped bending plate.

[0008] Preferably, the two sets of fixing bolt holes, fixing elongated holes, and upper fixing bolt holes are each on the same vertical line.

[0009] Preferably, the entire device is made of stainless steel through pressing and is formed in one piece.

[0010] Preferably, the rolled edge length is 1cm.

[0011] The beneficial effects of this utility model are:

[0012] After installing this device, an isolation barrier is formed at the simplified contact wire ratchet location, effectively isolating the potential for equipment tripping caused by the exposed electrical side of bird nest branches. Its main protection area reaches 1.63m². 2 Its ventilation design effectively solves the wind resistance problem caused by strong winds on elevated railways. The design of the bird-proof plate's bending point allows for multiple bolt fixation points on the existing contact wire supports, ensuring a firm installation. After installation, it can completely and tightly fit the contact wire supports, eliminating any possibility of tree branches protruding from the bird-proof plate. This achievement 100% prevents the problem of contact wire equipment tripping due to bird nests and protruding tree branches caused by simplified contact wire equipment, effectively ensuring the safety of EMU train passages, improving passenger satisfaction, and effectively reducing the labor intensity of frontline staff in removing bird nests.

Detailed Implementation

[0016] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0017] Example 1

[0018] like Figure 1 and Figure 2As shown, this utility model includes a fixing plate 1, fixing bolt holes 2, fixing elongated holes 3, a U-shaped bending plate 4, a blocking plate 6, and upper fixing bolt holes 7. The fixing plate 1 is rectangular. Fixing bolt holes 2 are provided at each of the four corners of the fixing plate 1. A fixing elongated hole 3 is provided between every two fixing bolt holes 2 and is located on the long side of the fixing plate 1. A U-shaped bending plate 4 is vertically connected to one side of the fixing plate 1. A blocking plate 6 is vertically installed on the other side of the U-shaped bending plate 4. The blocking plate 6 is rectangular and has two sets of upper fixing bolt holes 7 at the top of one side of the U-shaped bending plate 4.

[0019] The entire assembly can be installed with the bolts of the existing contact wire support. The fixing plate 1 is installed at the bolt position of the contact wire support. At the same time, the fixing elongated hole 3 provides sufficient space for the bolts at that position due to size or fixing position issues. The U-shaped bending plate 4 utilizes the original grid, through which the present invention is positioned and fixed firmly. Then, the upper fixing bolt hole 7 on the blocking plate 6 is fixed. The installation is simple and firm.

[0020] To facilitate fixing and cutting, the fixing plate 1 and the U-shaped bending plate 4 have the same width. The side of the U-shaped bending plate 4 that is connected to the long side of the fixing plate 1 is also connected to the long side of the blocking plate 6, which also facilitates cutting.

[0021] This utility model also includes an extended bending plate 5, ventilation holes 8, and rolled edges 9. The extended bending plate 5 is connected to the side of the U-shaped bending plate 4 connected to the blocking plate 6 and is along the short side of the blocking plate 6 not connected to the U-shaped bending plate 4. The ventilation holes 8 are long, rounded rectangles. Multiple sets of ventilation holes 8 are provided and are opened on the part of the blocking plate 6 not connected to the U-shaped bending plate 4. The rolled edges 9 are connected to the two sides of the blocking plate 6 located on the U-shaped bending plate 4.

[0022] The extended bending plate 5 is an extension of the original U-shaped bending plate 4, which strengthens the barrier. At the same time, the ventilation hole 8 can effectively solve the wind resistance problem caused by strong winds on the elevated railway. The rolled edge can better protect the ratchet, prevent birds from building nests, and make it easier to distinguish the front and back.

[0023] The fixing plate 1 and the U-shaped bending plate 4 are on the same plane, and the plane area of ​​the fixing plate 1 is smaller than that of the U-shaped bending plate 4, to ensure that the installation is level and to prevent gaps from causing the installation to be unstable.

[0024] The two sets of fixing bolt holes 2, fixing elongated holes 3 and upper fixing bolt holes 7 are each on the same vertical line, and are in the same position as the bolts on the contact wire support.

[0025] This utility model is made entirely of stainless steel through pressing, forming it in one piece. It is simple to manufacture, lightweight, and easy to install.

[0026] The rolled edge 9 is 1cm long, which can be changed according to the actual situation.
