Description

Technical Field

[0001] The present invention relates to the technical field of anti-bird overhead fittings, and specifically provides an overhead fitting with an anti-bird damage structure. Background Art

[0002] An anti-bird overhead fitting is a special device applied to overhead power line facilities. It is mainly used to prevent birds from staying, building nests, etc. in the overhead fitting and its surrounding areas, and avoid line failures caused by bird activities, such as short circuits, tripping, etc. Its structure usually includes multiple components working together, such as ear plate seats, I-shaped platforms with specific shapes and functions, as well as handles, card strips, T-shaped frames, guide seats, cross bars, T-shaped round bars, springs, sliders, articulated rods, toothed rods, gears, etc. combined through various connection methods, for realizing functions such as installation, adjustment, and bird repelling.

[0003] An anti-bird damage device with an umbrella skirt structure disclosed in Patent No. CN213519393U includes a core rod, top fittings and bottom fittings respectively arranged at both ends of the core rod, a grading ring connected to the top fitting, and an anti-bird umbrella skirt arranged on the grading ring. A dynamic bird repelling mechanism is also arranged on the anti-bird umbrella skirt. The grading ring includes two half-grading rings, a fixed clamp arranged on one of the half-grading rings, and a movable clamp arranged on the other half-grading ring.

[0004] When the anti-bird damage device with an umbrella skirt structure is used, although it can utilize the dynamic bird repelling mechanism to rotate the rotating plate under the action of the micro-motor and drive through the flexible shaft, to avoid bird perching to the greatest extent, it is not convenient to replace and install anti-bird mechanisms with different sizes and specifications according to actual situations, so the device needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide an overhead fitting with an anti-bird damage structure to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: An overhead fitting with an anti-bird damage structure includes a fitting rod frame. An installation mechanism is arranged at the top of the fitting rod frame, an anti-bird mechanism is arranged at the top of the installation mechanism, and an adjustment mechanism is arranged on the surface of the fitting rod frame; The installation mechanism includes a T-shaped block, which is arranged inside the fitting rod frame. A I-shaped platform is fixedly connected to the top of the T-shaped block. Four ends of the top of the I-shaped platform are respectively fixedly connected with T-shaped round rods. A first spring is fixedly connected to one end of the T-shaped round rod. A guide seat is fixedly connected to one end of the first spring. A cross bar is fixedly connected to the left side of the surface of the guide seat. A slider is arranged inside the guide seat. There are two groups of sliders. A second spring is fixedly connected between two adjacent sliders. One end of the slider is internally hinged with a hinge rod. A toothed rod is fixedly connected to the inside of one end of the hinge rod. A gear is fixedly connected to the surface of the toothed rod. A T-shaped frame is fixedly connected to the middle of the surface of the guide seat. A clamping strip is fixedly connected to the inside of the top of the T-shaped frame. A handle is fixedly connected to the left end of the clamping strip.

[0007] According to the above technical solution, a guide groove is opened inside the top of the fitting rod frame, and the surface of the T-shaped block is slidably connected to the inside of the guide groove. Since the thickness of the fitting rod frame of the overhead fitting is different, and the thickness of the wires carried is also different, this design allows the anti-bird mechanism of different sizes and specifications to be replaced and installed accordingly according to the actual situation, making the device applicable to different anti-bird operation scenarios and greatly improving the versatility and adaptability of the device.

[0008] According to the above technical solution, a perforation is opened inside the T-shaped round rod, the surface of the cross bar is slidably connected to the inside of the perforation, a T-shaped groove is opened inside the guide seat, and the surface of the slider is slidably connected to the inside of the T-shaped groove. When the guide seat moves, it needs to overcome the elastic force of the first spring. The existence of the first spring, on the one hand, plays a buffering role to avoid damaging the device due to sudden external force impact during the installation process. On the other hand, it can keep the guide seat at the initial position without external force, providing a reset basis for subsequent installation operations.

[0009] According to the above technical solution, there are two groups of gears symmetrically, and the two adjacent gears are meshed with each other. The upper and lower ends of the toothed rod are respectively rotatably connected to the upper and lower ends inside the I-shaped platform.

[0010] According to the above technical solution, the anti-bird mechanism includes an ear plate seat, which is arranged on the top of the I-shaped platform. A long rod is rotatably connected inside the ear plate seat. A connecting rod is rotatably connected to the surface of the long rod. A guide block is hinged to the bottom end of the connecting rod. A third spring is fixedly connected to one end of the guide block. A cross seat is arranged on the surface of the third spring. The bottom end of the cross seat is fixedly connected to the middle of the top of the ear plate seat. The two ends of the long rod are respectively.

[0011] According to the above technical solution, a guide groove is opened inside the horizontal seat. There are two guide blocks, and the two guide blocks are respectively slidably connected to the inside of the guide groove of the bird repellent mechanism. One end of the third spring is fixedly connected to the inside of the guide groove. Bayonet openings are respectively opened on both sides of the ear plate seat, and the surface of the clamping strip matches the inside of the bayonet opening. The guide block slides and resets under the limiting action inside the horizontal seat, so that the bird repellent thorn returns to the initial state, preparing for the next bird repellent work. This design of automatic reset greatly improves the use efficiency of the bird repellent device and can continuously play the role of bird repellent without manual intervention.

[0012] According to the above technical solution, the adjusting mechanism includes an L-shaped block, and the L-shaped block is fixedly connected to the top end of the front surface of the T-shaped block. A fourth spring is fixedly connected to the front surface of the L-shaped block. One end of the fourth spring is fixedly connected to a T-shaped plate. A T-shaped rod is fixedly connected to the inside of the T-shaped plate. A positioning strip is fixedly connected to the top end of the front surface of the L-shaped block. A clamping rod is arranged inside the positioning strip. A positioning strip is fixedly connected to the surface of the fitting rod frame.

[0013] According to the above technical solution, a positioning hole is opened on the surface of the positioning strip, and one end of the surface of the T-shaped rod matches the inside of the positioning hole.

[0014] According to the above technical solution, a rectangular hole is opened inside the T-shaped plate, and the surface of the positioning strip is slidably connected to the inside of the rectangular hole. A clamping hole is opened on the surface of the positioning strip, and the surface of the clamping rod matches the inside of the clamping hole. A round hole is opened on the front surface of the T-shaped plate, and the surface of the clamping rod is inserted into the round hole. The limitation of the L-shaped block and the T-shaped block inside the fitting rod frame is released. In this way, the position of the bird repellent mechanism can be flexibly adjusted according to the actual distribution of birds, so that it can more accurately perform bird repellent operations on the bird inhabiting area, further improving the bird repellent effect.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. For the overhead fitting with a bird damage prevention structure, through the provided installation mechanism, the clamping strips on both sides move and are clamped into the inside of the ear plate seat, thus completing the installation operation of the ear plate seat. Through such an installation method, the installation of the bird repellent mechanism can be conveniently realized, and then the corresponding bird repellent work can be conveniently carried out. Moreover, due to the different thicknesses of the fitting rod frames of the overhead fittings and the different thicknesses of the wires carried, this design allows the installation of bird repellent mechanisms of different sizes and specifications according to the actual situation, enabling the device to be applicable to different bird repellent operation scenarios and greatly improving the versatility and adaptability of the device.

[0016] 2. The overhead hardware with a bird-proof structure has an installation mechanism, and the guide seat cooperates with the T-shaped round rod through a cross bar. The cross bar is limited inside the T-shaped round rod, so that the guide seat can only move along the axial direction of the T-shaped round rod under the drive of the T-shaped frame. At the same time, the guide seat needs to overcome the elastic force of the first spring when moving. The existence of the first spring, on the one hand, plays a buffering role to avoid damage to the device due to sudden external force impact during the installation process. On the other hand, it can keep the guide seat in the initial position when there is no external force, providing a basis for resetting for subsequent installation operations.

[0017] 3. The overhead hardware with bird-proof structure has a bird-proof mechanism. When the bird flies away, the external force acting on the bird-repelling spike disappears, and the third spring releases its stored elastic potential energy to push the T-shaped cylinder and the bird-repelling spike to rotate in the opposite direction. In this process, the guide block slides and resets under the limit action inside the cross seat, so that the bird-repelling spike returns to its initial state and is ready for the next bird-repelling work. This automatic reset design greatly improves the use efficiency of the bird-repelling device, and can continuously play a bird-repelling role without manual intervention.

[0018] 4. The overhead hardware with a bird-proof structure has an adjusting mechanism. When the T-shaped rod is pulled, the L-shaped block and the T-shaped block will be moved together to make them leave the positioning bar. The positioning bar has a positioning and limiting effect on the L-shaped block and the T-shaped block. When they leave the positioning bar, the limit of the L-shaped block and the T-shaped block in the hardware rod frame is released. In this way, the position of the bird-proof mechanism can be flexibly adjusted according to the actual distribution of the birds, so that it can perform bird-proof operations more accurately in the bird's habitat, further improving the bird-proofing effect.

[0022] The present invention provides the following technical solutions: Embodiment 1

The upper and lower ends of the toothed rod 26 are respectively rotatably connected with the upper and lower ends inside the I-shaped platform 22. Since the thickness of the fitting rod frame 1 of the overhead fitting is different and the thickness of the wires carried is also different, this design allows the anti-bird mechanism 3 of different sizes and specifications to be replaced and installed accordingly according to the actual situation, making the device applicable to different anti-bird operation scenarios and greatly improving the versatility and adaptability of the device. Embodiment 2

[0025] Refer to Figures 1-8 , and on the basis of Embodiment 1, the anti-bird mechanism 3 is further obtained to include an ear plate seat 31 which is arranged on the top of the I-shaped platform 22.

[0026] Further, a guide groove is provided inside the horizontal seat 36. There are two guide blocks 34, and the two guide blocks 34 are respectively slidably connected to the inside of the guide groove of the bird repelling mechanism 3. One end of the third spring 35 is fixedly connected to the inside of the guide groove. Bayonet openings are respectively provided on both sides of the ear plate seat 31. The surface of the clamping strip 29 matches the inside of the bayonet opening. The guide block 34 slides and resets under the limiting action inside the horizontal seat 36, so that the bird repelling thorn 38 is restored to the initial state, preparing for the next bird repelling work. This design of automatic reset greatly improves the use efficiency of the bird repelling device and can continuously play the role of bird repelling without manual intervention. Embodiment 3

[0027] Refer to Figures 1-8 , and on the basis of Embodiment 1, the adjusting mechanism 4 is further obtained. The adjusting mechanism 4 includes an L-shaped block 41. The L-shaped block 41 is fixedly connected to the top end of the front surface of the T-shaped block 21. A fourth spring 42 is fixedly connected to the front surface of the L-shaped block 41. One end of the fourth spring 42 is fixedly connected to a T-shaped plate 43. A T-shaped rod 44 is fixedly connected to the inside of the T-shaped plate 43. A clamping position strip 46 is fixedly connected to the top end of the front surface of the L-shaped block 41. A clamping rod 47 is arranged inside the clamping position strip 46. A positioning strip 45 is fixedly connected to the surface of the fitting rod frame 1. A positioning hole is provided on the surface of the positioning strip 45. One end of the surface of the T-shaped rod 44 matches the inside of the positioning hole.

[0028] Further, a rectangular hole is provided inside the T-shaped plate 43. The surface of the clamping position strip 46 is slidably connected to the inside of the rectangular hole. A clamping position hole is provided on the surface of the clamping position strip 46. The surface of the clamping rod 47 matches the inside of the clamping position hole. A round hole is provided on the front surface of the T-shaped plate 43. The surface of the clamping rod 47 is inserted into the round hole. When they are separated from the inside of the positioning strip 45, the limitation of the L-shaped block 41 and the T-shaped block 21 inside the fitting rod frame 1 is released. In this way, the position of the bird repelling mechanism 3 can be flexibly adjusted according to the actual distribution of the birds, so that it can more accurately perform bird repelling operations on the bird roosting areas, further improving the bird repelling effect.

[0029] During the actual operation process, when this device is in use, the ear plate seat 31 is steadily placed on the top of the I-shaped table 22. The I-shaped table 22 serves as the basic support part of the entire installation structure, and its shape design can provide a stable placement plane for the ear plate seat 31, ensuring the accuracy and stability of subsequent installation operations. Pull one of the handles 291. The handle 291 is connected to the clamping bar 29 and the T-shaped frame 28. When the handle 291 is pulled, it will drive the clamping bar 29 and the T-shaped frame 28 to move synchronously. During this process, the movement of the T-shaped frame 28 plays a key transmission role. The T-shaped frame 28 is connected to the guide seat 24. The guide seat 24 cooperates with the T-shaped round bar 23 through the cross bar 232. The cross bar 232 is limited inside the T-shaped round bar 23, which enables the guide seat 24 to move only along the axial direction of the T-shaped round bar 23 under the drive of the T-shaped frame 28. At the same time, when the guide seat 24 moves, it needs to overcome the elastic force of the first spring 231. The existence of the first spring 231, on the one hand, plays a buffering role to prevent the device from being damaged due to sudden external force impacts during the installation process. On the other hand, it can keep the guide seat 24 at the initial position when there is no external force, providing a basis for resetting in subsequent installation operations; During the movement of the guide seat 24, the slider 25 inside the guide seat 24 also moves accordingly. The slider 25 is connected to the articulated rod 242. The articulated rod 242 rotates under the elastic action of the second spring 241. The elastic force of the second spring 241 makes the articulated rod 242 have a certain resistance and reset ability when rotating. When the guide seat 24 moves, the movement of the slider 25 drives the articulated rod 242 to rotate, and then drives the rack 26 connected to the articulated rod 242 to move. The rack 26 meshes with the gear 27. The movement of the rack 26 will cause the gear 27 to rotate. Since the two gears 27 are meshed with each other, the rotation of one gear 27 will drive the other gear 27 to rotate in the opposite direction through the meshing action. The design of this gear transmission structure can convert the pulling action of a single handle 291 into the synchronous opposite movement of the clamping bars 29 on both sides. Finally, the clamping bars 29 on both sides move and are clamped into the ear plate seat 31, thus completing the installation operation of the ear plate seat 31. Through such an installation method, the installation of the bird prevention mechanism 3 can be conveniently achieved, and then the corresponding bird repelling work can be conveniently carried out. Moreover, due to the different thicknesses of the fitting rod frames 1 of the overhead fittings and the different thicknesses of the wires carried, this design allows for the corresponding replacement and installation of bird prevention mechanisms 3 of different sizes and specifications according to the actual situation, making the device applicable to different bird prevention operation scenarios and greatly improving the versatility and adaptability of the device; In addition, when driving away birds, when the bird lands on the bird-driving spike 38, the following series of actions will occur. Due to the influence of the bird's own gravity, a downward force will be applied to the bird-driving spike 38. The bird-driving spike 38 is installed on the T-shaped cylinder 37, and the T-shaped cylinder 37 is connected to the guide block 34. The guide block 34 can only slide under the limit of the inside of the cross seat 36. When the gravity of the bird acts on the bird-driving spike 38, the bird-driving spike 38 will drive the T-shaped cylinder 37 and the guide block 34 to rotate accordingly. This rotation will make the bird lose balance and unable to stand firmly on the bird-driving spike 38, thereby playing a corresponding bird-proof operation, effectively preventing the bird from staying on the overhead hardware, and when the bird flies away, the bird-driving spike 38 on the T The third spring 35 is used to reset the T-shaped cylinder 37. One end of the third spring 35 is connected to the T-shaped cylinder 37, and the other end is connected to a fixed position inside the cross seat 36. When the bird flies away, the external force acting on the bird-repelling spike 38 disappears, and the third spring 35 releases its stored elastic potential energy to push the T-shaped cylinder 37 and the bird-repelling spike 38 to rotate in the opposite direction. In this process, the guide block 34 is slid and reset under the limiting action inside the cross seat 36, so that the bird-repelling spike 38 is restored to the initial state, ready for the next bird-repelling work. This automatic reset design greatly improves the use efficiency of the bird-repelling device, and can continuously play the bird-repelling role without manual intervention. In addition, when performing operations related to overhead hardware, if it is necessary to adjust the bird-proofing mechanism 3 according to the actual distribution of birds, first pull out the clamping rod 47 to disengage it from the inside of the clamping strip 46. The clamping rod 47 and the clamping strip 46 form a limiting structure. Under normal circumstances, the clamping rod 47 is inserted into the inside of the clamping strip 46 to play a fixing role. When it is necessary to adjust the bird-proofing mechanism 3, pull out the clamping rod 47 to release this limit, and then pull the T-shaped rod 44, which is connected to the L-shaped block 41 and the T-shaped block 21. When the T-shaped When the rod 44 is moved, the L-shaped block 41 and the T-shaped block 21 will be driven to move together, so that they will be separated from the interior of the positioning bar 45. The positioning bar 45 has a positioning and limiting effect on the L-shaped block 41 and the T-shaped block 21. When they are separated from the interior of the positioning bar 45, the limit of the L-shaped block 41 and the T-shaped block 21 in the hardware rod frame 1 is released. In this way, the position of the bird-proofing mechanism 3 can be flexibly adjusted according to the actual distribution of the birds, so that it can perform bird-proofing operations more accurately in the bird's habitat area, further improving the bird-proofing effect.
