However, in actual operation, pole-mounted disconnect switches face many problems, among which bird nesting behavior poses a serious threat to their safe operation.

[0003] The existing pole-mounted disconnect switches on 10kV distribution lines are all installed using a double crossarm method. While this installation method itself has a certain degree of stability and reliability, the specific characteristics of the crossarm and pole structure result in the close proximity of the two disconnect switches, providing convenient nesting sites for birds. When birds nest near the disconnect switches, it may cause phase-to-phase short circuits, leading to line tripping, increased power outage time, and seriously affecting power supply reliability and users' electricity needs. It also poses a hidden danger to the safe operation of the power system. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an isolation baffle based on a pole-mounted disconnect switch. The baffle body is installed on the disconnect switch by a magnetic adsorption component. The installation process is simple and easy to operate, without complicated tools and cumbersome steps, which greatly shortens the installation time and improves the installation efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides an isolation baffle based on a pole-mounted disconnect switch, comprising:

[0006] The baffle body is used to shield the disconnect switch;

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1-6 As shown, the isolation baffle based on a pole-mounted disconnect switch of this utility model includes:

[0031] Baffle body 1, used to shield the isolating switch;

[0032] Side column plate 2 is disposed on the baffle body 1;

[0033] A magnetic adsorption component 3 is disposed on the side column plate 2 for adsorbing the double crossarms between the isolating switches to fix the isolation baffle. The magnetic adsorption component 3 includes a screw 31, a support plate 32 and a magnet 33. One end of the screw 31 is inserted into the support plate 32 and is fixed to the support plate 32 by a first locking nut and a second locking nut. The other end of the screw 31 is inserted into the side column plate 2 and is fixed to the side column plate 2 by a third locking nut.

[0034] The magnetic adsorption component 3 achieves a stable connection between the baffle body 1 and the disconnecting switch through the cooperation of the screw 31, the support plate 32 and the magnet 33, and the fixing of the locking nut. This fixing method is firm and reliable, can resist the influence of natural factors such as wind and rain, ensures the stability of the baffle body 1 during long-term use, and ensures the safe operation of the power system.

[0035] In this embodiment, a buffer spring 34 is sleeved on the outer side of the screw 31, between the second locking nut and the side column plate 2. The buffer spring 34 sleeved on the outer side of the screw 31 can absorb some of the impact energy, providing a certain degree of buffer protection when the baffle body 1 is subjected to external impact, reducing the direct impact on the baffle body 1 and the disconnecting switch, protecting the disconnecting switch from damage, and extending the service life of the equipment. In addition, the buffer spring 34 improves the reliability of the baffle body 1 in harsh environments. For example, under vibration conditions such as wind and rain, the buffer spring 34 can effectively reduce the loosening or damage of components caused by vibration and impact, ensuring that the baffle body 1 always maintains a good working condition and ensuring the stable operation of the power system. The elasticity of the buffer spring 34 can provide a certain preload adjustment function. During installation, the elasticity of the buffer spring 34 can ensure that the connection between the screw 31 and the support plate 32 has an appropriate preload, so that the magnetic adsorption component 3 can be firmly adsorbed on the double crossarm. When disassembling, the elasticity of the buffer spring 34 can absorb some external force, so that the connection between the screw 31 and the support plate 32 will not be over-tightened due to external force. This elastic buffering effect makes the screw 31 easier to rotate during disassembly, reducing the disassembly difficulties caused by component jamming or over-tightening, making the disassembly of the screw 31 easier, thereby facilitating the disassembly of the isolation baffle.

[0036] The side of the baffle body 1 is provided with several equally spaced fixing holes (first type), and the side column plate 2 is provided with fixing holes (second type). After the locking fastener passes through the fixing holes (first and second types), the baffle body 1 and the side column plate 2 are fixedly connected. The design of fixing holes (first and second types) further enhances the connection stability between the baffle body 1 and the side column plate 2. This design makes the isolation baffle more stable during installation, reduces installation failures or malfunctions during operation caused by loose components, and improves the reliability of the entire device.

[0037] In this embodiment, there are four fixing holes one and four fixing holes two, and they correspond one-to-one.

[0038] The side column plate 2 has a positioning hole in the center of its front side to facilitate lifting the switch rod. This positioning hole facilitates the installation and maintenance of the baffle body 1. During installation, the switch rod can easily lift the baffle body 1 through the positioning hole, ensuring accurate positioning and reducing installation difficulty and labor intensity. Simultaneously, the positioning hole also facilitates quick disassembly and reinstallation of the baffle body 1 by operators during maintenance or replacement.

[0039] The front of the side column plate 2 is located on both sides of the positioning hole, with several mounting holes symmetrically arranged for installing the magnetic adsorption component 3. The symmetrical arrangement of the mounting holes ensures that the magnetic adsorption component 3 is evenly stressed during installation, enhancing the stability of the double crossarm connection between the baffle body 1 and the disconnecting switch. Simultaneously, this layout provides wider applicability to disconnecting switches of different models and specifications, allowing the baffle body 1 to better adapt to various complex installation environments.

[0040] A washer 35 is provided between the buffer spring 34 and the second locking nut. The use of the washer 35 can also prevent direct contact between the second locking nut and the buffer spring 34, reduce wear caused by friction, and improve the durability of the device. This is especially important for the baffle body 1, which needs to be used outdoors for a long time. It can effectively extend the service life of the device and reduce maintenance costs.

[0041] In this embodiment, the baffle body 1 is rectangular, and its length is adapted to the spacing between two adjacent disconnect switches. This design ensures that the baffle body 1 can completely shield the disconnect switches, effectively preventing phase-to-phase short circuits caused by foreign objects such as birds nesting. Through precise dimensional design, the baffle body 1 can fit tightly against the disconnect switches, improving the shielding effect and ensuring the safe operation of the power system.

[0042] The baffle body 1 is made of insulating material. This insulating material effectively prevents electric shock accidents caused by contact with live parts during installation and maintenance, ensuring the personal safety of operators. The use of insulating material also prevents the insulation performance of the disconnecting switch from deteriorating due to moisture, corrosion, and other natural factors, improving the equipment's protective performance, extending the service life of the disconnecting switch, and ensuring the stable operation of the power system.

[0043] In this embodiment, the outer surface of the baffle body 1 is provided with a reflective coating. The reflective coating on the outer surface of the baffle body 1 can reflect light at night or in low-light environments, serving as a warning.

[0044] The installation process for the isolation baffle based on the pole-mounted disconnect switch is as follows:

[0045] (1) Place the baffle body 1 in a suitable position to ensure that its length is compatible with the spacing between the two adjacent disconnect switches;

[0046] (2) Install the side column plate 2 on the side of the baffle body 1;

[0047] (3) Use a locking fastener to pass through the fixing hole 1 on the side of the baffle body 1 and the fixing hole 2 on the side column plate 2 to fix the two together;

[0048] (4) Insert one end of the screw 31 onto the support plate 32;

[0049] (5) Use the first locking nut and the second locking nut to fix the screw 31 to the support plate 32;

[0050] (6) A buffer spring 34 is fitted on the outside of the screw 31 between the side column plate 2 and the second locking nut;

[0051] (7) Insert the other end of the screw 31 into the side column plate 2;

[0052] (8) Use the third locking nut to fix the screw 31 to the side column plate 2;

[0053] (9) Install a washer 35 between the second locking nut and the buffer spring 34 to reduce wear and improve durability;

[0054] (10) Use the lever to align with the positioning hole on the side column plate 2, lift the baffle body 1 and send it to the designated position;

[0055] (11) Finally, the screw 31 is rotated by a lever with a nut sleeve 101 on its head, thereby rotating the support plate 32 and causing the magnet 33 to be attracted to the double crossarm, thus completing the installation of the baffle body 1. Figure 7 The image shows a lever with a nut sleeve 101 at the head.

[0056] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
