Description

Technical Field

[0001] The utility model belongs to the technical field of bird-proof covers, and particularly relates to a novel bird-proof protective cover. Background Art

[0002] In recent years, the proportion of power transmission line tripping caused by bird damage has been increasing. There are many kinds of bird prevention devices for transmission lines, each with its own advantages and disadvantages. At present, there is no practical and cost-effective bird prevention facility that can prevent bird damage to transmission lines.

[0003] Currently, power grid companies are using bird-blocking screens to prevent birds from dropping foreign objects like weeds and feces onto towers, particularly on the crossarms that hold insulator strings. These foreign objects can easily cause flashovers and breakdowns. While bird-blocking screens have significantly improved the effectiveness of preventing large birds from landing on towers, they also have limitations and areas for improvement in field applications. 1. Currently, bird-blocking screens are often secured with aluminum wire, requiring multiple ties for secure installation. There is no universal installation method, making them inconvenient and time-consuming. 2. Traditional bird-blocking screens cannot be moved once secured. During line maintenance, the screens must be disassembled and set aside, then replaced after the work is complete. This increases the workload of overhead operations. Repeated disassembly and installation can lead to fatigue on the screen mounting hardware, increasing the workload for maintenance personnel. 3. If the screen mounting wire deteriorates, the screen could fall from height, potentially creating a serious risk of personal injury. 4. Currently, the installation of bird-proof baffles is usually carried out using live work, and the use of aluminum wire binding wire during the binding process will increase the risk of electric shock for construction workers.

[0004] Therefore, in order to solve the above problems, it is urgent to design a novel bird-proof cover. Utility Model Content

[0005] The purpose of this utility model is to provide a new bird-proof shield that solves the technical defects of existing bird-proof baffles, further improves the bird-proofing effect, and does not need to be disassembled during maintenance work, reducing tedious disassembly and assembly steps and improving maintenance efficiency. In addition, the bird-proof shield is easy to install, stable and firm, and simple to operate. The specific technical solution is as follows:

[0006] A novel bird-proof shield comprises a conical sector, a supporting structure and a fixed base. The fixed base is mounted on the angle steel of an iron tower, the supporting structure is mounted on the fixed base, and the conical sector is rotatably mounted on the supporting structure.

[0007] Preferably, a plurality of windward plates are equidistantly arranged on the conical sector.

[0008] Preferably, the support structure includes a fixed sleeve, an adjusting rod sleeve and a tension spring, the adjusting rod sleeve is slidably arranged on the fixed sleeve, and the tension spring is installed in the adjusting rod sleeve.

[0009] Preferably, the fixed sleeve is provided with a plurality of adjustment holes, and the adjusting rod sleeve is provided with a spring button matching the adjustment holes. The spring button is clamped in any of the adjustment holes, and the length of the adjusting rod sleeve extending out of the fixed sleeve is adjusted by cooperating with the spring button and the adjustment hole.

[0010] Preferably, a rod assembly is rotatably provided at the bottom center of the conical sector, and the rod assembly includes a rod and a limit sleeve. The rod is rotatably installed at the bottom center of the conical sector, and the limit sleeve is installed on the rod. The rod is inserted in the adjusting rod sleeve, and one end of the tension spring is connected to the bottom surface of the rod, and the other end is connected to the inner bottom surface of the adjusting rod sleeve.

[0011] Preferably, the diameter of the limiting sleeve is larger than the diameter of the adjusting rod sleeve.

[0012] Preferably, the fixed base includes a U-shaped clamp, a quick lock and a fixing bolt. The U-shaped clamp is provided with two quick locks. The U-shaped clamp is fixedly installed on the angle steel of the iron tower through the fixing bolts, and the fixing sleeve is inserted into the quick lock.

[0013] Preferably, the connection directions of the two quick locks are perpendicular to each other.

[0014] Preferably, the U-shaped fixture is made of stainless steel.

[0015] Preferably, the central angle of the conical sector is 120°.

[0016] Compared with the existing technology, the utility model has the following beneficial effects:

[0017] 1. The utility model provides a new type of bird-proof cover, which can be detachably installed on the angle steel of the iron tower through a fixed base to facilitate disassembly and movement during maintenance. At the same time, the setting of double quick locks facilitates the installation and fixation of two positions of the iron tower angle steel.

[0018] 2. The bird-proof cover provided by the utility model can be telescopically adjusted to adjust the protection height of the conical fan to cover and shield the low space on the cross arm of the insulator string of the iron tower, thereby preventing birds from building nests under the cover due to the support frame being too high.

[0019] 3. The conical fan surface in the bird-proof cover provided by the present invention has a certain slope, and the outer surface of the conical fan surface is a smooth surface (slippery surface), which can effectively prevent birds from standing firmly on the conical fan surface, and thus effectively prevent birds from stopping on the conical fan surface. At the same time, a windward plate is provided on the conical fan surface, which can be driven by the wind to rotate the conical fan surface, thereby further driving away the birds that stop. In a windless state, since there is a tension spring inside the bird-proof cover, when a bird stops on the fan surface, the conical fan surface will vibrate up and down under the action of the elastic force to prevent the bird from stopping.

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances. The following describes an embodiment of the present invention based on its overall structure.

[0030] Example

[0031] like Figures 1 to 3 As shown, a new type of bird-proof shield specifically includes a combined installed conical fan 1, a supporting structure 2 and a fixed base 3, wherein the fixed base 3 is fixedly installed on the angle steel of the iron tower by bolts, the supporting structure 2 is quickly inserted into the fixed base 3, and the conical fan 1 is rotatably installed on the supporting structure 2.

[0032] Preferably, a number of windward plates 110 are equidistantly arranged on the conical fan surface 1. With the help of wind force, the conical fan surface 1 can rotate on the supporting structure 2, further throwing off foreign objects attached to the conical fan surface 1, and effectively preventing birds from stopping.

[0033] In some preferred embodiments, the conical fan surface 1 has a certain slope, so the central angle of the conical fan surface 1 is 120°, and the outer surface of the conical fan surface 1 is a smooth surface (slippery surface), which can effectively prevent birds from standing firmly on the conical fan surface 1, and thus effectively prevent birds from stopping on the conical fan surface 1.

[0034] Preferably, the support structure 2 includes a fixed sleeve 210 , an adjusting rod sleeve 220 and a tension spring. The adjusting rod sleeve 220 is slidably disposed on the fixed sleeve 210 , and the tension spring is installed in the adjusting rod sleeve 220 .

[0035] In some preferred embodiments, the fixed sleeve 210 is provided with a plurality of adjustment holes 211, and the adjusting rod sleeve 220 is provided with a spring button 221 matching the adjusting hole 211. The spring button 221 is clamped in any of the adjusting holes 211. The length of the adjusting rod sleeve 220 extending out of the fixed sleeve 210 is adjusted by cooperating with the spring button 221 and the adjusting hole 211, so as to cover and shield the upper and lower spaces of the cross arms on the insulator string of the iron tower, thereby preventing birds from building nests under the shield due to the excessive height of the support frame.

[0036] Preferably, a rod assembly 120 is rotatably provided at the bottom center of the conical sector 1. The rod assembly 120 includes a rod 121 and a limiting sleeve 122. The rod 121 is rotatably mounted at the bottom center of the conical sector 1 (or the conical sector 1 and the rod 121 can rotate relative to each other). The limiting sleeve 122 is mounted on the rod 121. The rod 121 is inserted into the adjusting rod sleeve 220. One end of the tension spring is connected to the bottom surface of the rod 121, and the other end is connected to the inner bottom surface of the adjusting rod sleeve 220. The diameter of the limiting sleeve 122 is larger than the diameter of the adjusting rod sleeve 220 to limit the depth of the rod 121 inserted into the adjusting rod sleeve 220.

[0037] In the initial state, the lower bottom surface of the limiting sleeve 122 does not contact the upper end surface of the adjusting rod sleeve 220, and the conical fan surface 1 is supported entirely on the supporting structure 2 by the tension spring. When a bird stays on the conical fan surface 1, the tension spring is compressed under the action of multiple gravity. When the bird moves on the conical fan surface 1 again, the conical fan surface 1 will vibrate elastically under the action of elastic force, thereby effectively driving away the bird; when affected by wind, the conical fan surface 1 will also vibrate elastically on the supporting structure 2, thereby effectively shaking off foreign objects attached to its surface.

[0038] Preferably, the fixing base 3 includes a U-shaped fixture 310, a quick lock 320, and a fixing bolt 330. The U-shaped fixture 310 is provided with two quick locks 320. The U-shaped fixture 310 is fixedly mounted on the angle steel of the tower via the fixing bolts 330, and the fixing sleeve 210 is inserted into the quick lock 320. The U-shaped fixture 310 is made of stainless steel and has a strong supporting force, which can prevent damage to the fixture caused by high-altitude strong winds. At the same time, the detachable installation of the fixing bolts 330 facilitates the overall movement during maintenance.

[0039] In some preferred embodiments, the connection directions of the two quick locks 320 are perpendicular to each other. Various fixed base 3 structures have been studied to achieve fixation to various crossarms on transmission line towers, such as angle steel, steel pipe poles, and channel steel. This project addresses the shortcomings of existing transmission line bird-proofing baffles. Through technical improvements to existing transmission line bird-proofing baffles, it not only facilitates bird prevention, but also allows for easy movement to ensure maintenance work, and features easy installation and simple operation. The dual quick locks 320 facilitate installation and fixation of the tower angle steel at two locations.

[0040] To sum up, the bird-proof cover provided by the present invention can be telescopically adjusted to adjust the protective height of the conical fan surface, so as to cover and shield the low space on the cross arm of the insulator string of the iron tower, and prevent birds from falling under the protective cover due to the support frame being too high; the conical fan surface in the bird-proof cover provided by the present invention has a certain slope, and the outer surface of the conical fan surface is a smooth surface (slippery surface), which can effectively prevent birds from standing firmly on the conical fan surface, and thus effectively prevent birds from stopping on the conical fan surface. At the same time, a windward plate is provided on the conical fan surface, which can be driven by the wind to rotate the conical fan surface, and further drive away the stopped birds; in a windless state, since there is a tension spring inside the bird-proof cover, when a bird stops on the fan surface, the conical fan surface will vibrate up and down under the action of the elastic force to prevent the bird from stopping.

These descriptions are not intended to limit the present invention to the precise form disclosed, and it is obvious that many changes and variations can be made based on the above teachings.
