Description

Technical Field

[0001] This invention belongs to the technical field of power protection facilities, and more specifically, relates to a bird spike that is easy to store. Background Technology

[0002] Bird spikes are a product developed to prevent birds from nesting on power transmission towers. They are installed on the upper part of the crossarm of the towers of power transmission and transformation equipment. They are composed of multiple steel wires arranged in a spread-out shape, which effectively prevents birds from fighting, perching, or nesting directly above the porcelain insulator strings of the conductors, ensuring the smooth operation of the line and reducing the occurrence of power outages.

[0003] The existing bird spikes consist of a bird spike body and a storage shell located below the bird spike body. The bottom of the storage shell is used to fix it to the power tower pole. A lifting component is installed inside the storage shell to drive the bird spike body to slide down into the storage shell, which facilitates the handling of the bird spike in its stored state.

[0004] When the bird spikes are positioned above the housing, the housing significantly increases the height of the bird spike device, causing the overall center of gravity to shift upwards. This is especially problematic in windy conditions, where the housing experiences excessive impact, resulting in poor overall stability of the bird spike device. Summary of the Invention

[0005] The purpose of this invention is to provide a bird spike that is easy to store, so as to solve the technical problem that the presence of a storage shell in the prior art leads to poor overall stability of the bird spike device.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a bird spike that is easy to store, including a bird spike body, and further comprising:

[0007] The base is used to fix it to the power tower pole, and the bird spike body is inserted into the middle of the upper surface;

[0008] A multi-stage telescopic cover is provided on the upper surface of the base and surrounds the outside of the bird spike body, having the freedom to extend and retract vertically;

[0009] Multiple connecting rods, each of which is fixed at the top of the multi-stage telescopic cover and vertically slidably connected at the bottom to the base; and

[0010] A drive mechanism is mounted on the base and connected to the plurality of connecting rods. The drive mechanism is used to drive the plurality of connecting rods to rise and fall.

[0011] The bird spike body has a storage state and a use state. The drive mechanism drives the connecting rod to rise, and the multi-stage telescopic cover retracts the bird spike body inside, so that the bird spike body is in the storage state. The drive mechanism drives the connecting rod to fall, and the multi-stage telescopic cover folds on the base, so that the bird spike body is in the use state.

[0012] In one possible implementation, based on the above technical solutions, the base has through holes corresponding to the connecting rods, the through holes allowing the connecting rods to pass through, and the base has an annular groove communicating with all the through holes; the driving mechanism includes:

[0013] A drive rod is rotatably connected to one side of the base, with one end of the drive rod located on the outside of the base and the other end extending into the annular groove;

[0014] Multiple threaded sleeves, each corresponding to a through hole, are rotatably connected within the through hole; each threaded sleeve is threadedly connected to the corresponding connecting rod.

[0015] A linkage component is disposed within the annular groove and acts between the drive rod and all the threaded sleeves;

[0016] When the drive rod rotates, the linkage component drives all the threaded sleeves to rotate synchronously, so that all the connecting rods rise and fall synchronously.

[0017] In one possible implementation, based on the above technical solutions, the linkage component includes:

[0018] A bevel gear is coaxially fixed to one end of the drive rod located within the annular groove.

[0019] Multiple linked gears, each corresponding to a threaded sleeve, are coaxially fixed to the outside of the threaded sleeve; and

[0020] A linkage ring is rotatably connected within the annular groove. The outer side of the linkage ring has an annular bevel tooth portion that meshes with the bevel gear, and the inner side has an annular straight tooth portion that meshes with the linkage gear.

[0021] In one possible implementation, in conjunction with the above technical solutions, the driving mechanism further includes:

[0022] Multiple locking components are disposed below the base and correspond one-to-one with the connecting rod; wherein the bottom end of the connecting rod extends downward through the through hole and is threadedly connected to the locking component.

[0023] In one possible implementation, based on the above technical solutions, a lifting seat is fixed to the bottom of the bird spike body, the lifting seat is slidably connected to the base, and a lifting component is provided between the lifting seat and the linkage component;

[0024] The linkage component drives the screw sleeve to rotate, thereby raising and lowering the connecting rod, and also drives the lifting seat to slide in the opposite direction to the connecting rod.

[0025] In one possible implementation, based on the above technical solutions, a receiving cavity is formed in the middle of the upper surface of the base for the lifting seat to slide into; the lifting assembly includes:

[0026] A threaded ring, rotatably connected within the receiving cavity and threadedly connected to the lifting seat; and

[0027] A connecting gear ring is coaxially fixed to the outside of the threaded ring and meshes with all the linkage gears;

[0028] When the linkage gear drives the screw sleeve and the connecting gear ring to rotate, the connecting rod and the lifting seat slide in opposite directions.

[0029] In conjunction with the above technical solutions, in one possible implementation, the lifting component further includes:

[0030] Two eccentric rods are vertically fixed on both sides inside the receiving cavity and pass through the lifting seat.

[0031] In one possible implementation, based on the above technical solutions, the cover body of the first inner layer of the multi-level telescopic cover is defined as the top cover body.

[0032] When the bird spike body is in the retracted state, the top of the bird spike body is tucked inside the top cover, and the inner diameter of the top cover gradually increases from bottom to top.

[0033] In one possible implementation, in conjunction with the above technical solutions, when the bird spike body is in use, the top of each level of the multi-level telescopic cover is stepped from the outside to the inside.

[0034] In one possible implementation, based on the above technical solutions, the base is divided into upper and lower layers by the rotation axis of the drive rod, the perforation and the annular groove are formed between the upper and lower layers of the base, and the two layers of the base are detachably fixed.

[0035] The beneficial effects of the bird spikes provided by this invention, which are easy to store, are as follows: Compared with the prior art, this invention allows the bird spike body to flexibly switch between a stored state and a used state. In the used state, the drive mechanism lowers the connecting rod, and the multi-stage telescopic cover folds onto the base. While achieving the storage function of the bird spike body, the height of the bird spike device is significantly reduced, solving the problem of the overall center of gravity shifting upward and the poor stability of the device caused by the storage shell in the used state in the prior art. Since the multi-stage telescopic cover fits snugly onto the base after folding, the overall height of the device is greatly reduced, making the center of gravity closer to the connection between the base and the power tower. Under strong winds, the impact force is significantly reduced, and the overall stability of the bird spike device during use is significantly improved. Attached Figure Description

[0052] To make the technical problems, technical solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of this application, not all of them. The specific embodiments described herein are only used to explain the invention and are not intended to limit the invention.

However, under the premise that those skilled in the art understand the concept of the present invention, they can implement the above-mentioned specific forms and arrangements in a well-known manner.

[0054] When a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0056] The present invention will now describe a bird spike that is easy to store.

[0057] like Figures 1 to 3 As shown, one embodiment of the present invention provides a bird spike that is easy to store, including a bird spike body 1, a base 2, a multi-stage telescopic cover 3, multiple connecting rods 4, and a set of drive mechanisms 5; the base 2 is used to fix it to a power tower pole, and the bird spike body 1 is inserted into the middle of its upper surface; the multi-stage telescopic cover 3 is disposed on the upper surface of the base 2 and surrounds the outside of the bird spike body 1, having the freedom to extend and retract vertically; the top of each connecting rod 4 is fixed to the top of the multi-stage telescopic cover 3, and the bottom is vertically slidably connected to the base 2; the drive mechanism 5 is disposed on the base 2 and connected to the multiple connecting rods 4, and the drive mechanism 5 is used to drive the multiple connecting rods 4 to rise and fall.

[0058] The bird spike body 1 has a storage state and a use state. The drive mechanism 5 drives the connecting rod 4 to rise, and the multi-stage telescopic cover 3 retracts the bird spike body 1 inside, so that the bird spike body 1 is in the storage state. The drive mechanism 5 drives the connecting rod 4 to fall, and the multi-stage telescopic cover 3 folds on the base 2, so that the bird spike body 1 is in the use state.

[0059] This embodiment provides a bird spike that is easy to store. Compared with the prior art, it allows the bird spike body 1 to flexibly switch between a storage state and a use state. When in the storage state, the drive mechanism 5 drives the connecting rod 4 to rise, and the multi-stage telescopic cover 3 retracts the bird spike body 1 inside, which can effectively protect the bird spike body 1 and prevent it from being damaged by collisions, friction, etc. during transportation and storage. At the same time, it can also prevent the sharp spikes of the bird spike body 1 from causing accidental injury to the operator, greatly improving the safety of operation.

[0060] In use, the drive mechanism 5 lowers the connecting rod 4, and the multi-stage telescopic cover 3 folds onto the base 2. While still providing storage for the bird spike protector 1, this significantly reduces the height of the bird spike device, solving the problem in existing technologies where the storage shell causes the overall center of gravity to shift upwards and resulting in poor stability during use. Because the multi-stage telescopic cover 3 folds and fits snugly onto the base 2, the overall height of the device is greatly reduced, bringing the center of gravity closer to the connection between the base 2 and the power tower. This significantly reduces the impact force in strong winds, thus greatly improving the overall stability of the bird spike protector during use.

[0061] like Figures 4 to 5 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0062] The base 2 has through holes 21 corresponding to the connecting rods 4, through which the connecting rods 4 pass. The base 2 has an annular groove 22 that connects all the through holes 21. The drive mechanism 5 includes a drive rod 51, a screw sleeve 52, and a linkage assembly 53. The drive rod 51 is rotatably connected to one side of the base 2, with one end of the drive rod 51 located outside the base 2 and the other end extending into the annular groove 22. The screw sleeves 52 correspond to the through holes 21 and are rotatably connected to the through holes 21. The screw sleeves 52 are threadedly connected to the corresponding connecting rods 4. The linkage assembly 53 is disposed in the annular groove 22 and acts between the drive rod 51 and all the screw sleeves 52.

[0063] When the drive rod 51 rotates, the linkage component 53 drives all the threaded sleeves 52 to rotate synchronously, so that all the connecting rods 4 rise and fall synchronously.

[0064] When the drive rod 51 rotates, it drives all the threaded sleeves 52 to rotate synchronously through the linkage component 53. Since the threaded sleeves 52 are threadedly connected to the connecting rods 4, the synchronous rotation of the threaded sleeves 52 enables all the connecting rods 4 to rise or fall synchronously. This ensures that the force on each part of the multi-stage telescopic cover 3 is uniform during the telescopic process, avoids problems such as skewing and jamming of the multi-stage telescopic cover 3 caused by asynchronous lifting and lowering of the connecting rods 4, and extends the service life of the multi-stage telescopic cover 3.

[0065] Meanwhile, one end of the drive rod 51 is located on the outside of the base 2, allowing operators to rotate it from the outside without needing to delve into the device, thus simplifying the operation process. Furthermore, the linkage component 53 is housed within the annular groove 22, which not only makes the structure more compact but also effectively protects the linkage component 53 from external interference and damage, improving the reliability and durability of the drive mechanism 5. In addition, the threaded connection between the screw sleeve 52 and the connecting rod 4 features precise transmission and good self-locking, ensuring that the connecting rod 4 remains stable after being raised or lowered to the designated position and will not move due to external forces, further guaranteeing the stability of the bird spike protector in both states.

[0066] like Figures 4 to 5 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0067] The linkage assembly 53 includes a bevel gear 531, a linkage gear 532, and a linkage ring 533. The bevel gear 531 is coaxially fixed to one end of the drive rod 51 located in the annular groove 22. The linkage gear 532 corresponds one-to-one with the threaded sleeve 52 and is coaxially fixed to the outside of the threaded sleeve 52. The linkage ring 533 is rotatably connected in the annular groove 22. The outer side of the linkage ring 533 has an annular bevel tooth portion that meshes with the bevel gear 531, and the inner side has an annular straight tooth portion that meshes with the linkage gear 532.

[0068] When the drive rod 51 rotates, the bevel gear 531 rotates accordingly. Since the annular bevel teeth on the outer side of the linkage ring 533 mesh with the bevel gear 531, the rotation of the bevel gear 531 drives the linkage ring 533 to rotate within the annular groove 22. The annular spur teeth on the inner side of the linkage ring 533 mesh with all the linkage gears 532, thereby driving all the threaded sleeves 52 to rotate synchronously. This ensures that the power of the drive rod 51 is transmitted evenly and stably to each threaded sleeve 52, guaranteeing that all connecting rods 4 achieve absolutely synchronous lifting and lowering, and avoiding inconsistent expansion and contraction of the multi-stage telescopic cover 3 due to uneven transmission.

[0069] The linkage component 53 has a compact structure and precise meshing relationship between the gears, which greatly improves the stability and reliability of the entire transmission system. It can maintain good transmission performance during long-term use, reduce the probability of failure, and extend the service life of the device. Even after replacing the bird spike body 1 several times, it can still be used normally.

[0070] like Figure 5 and Figure 6 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0071] The drive mechanism 5 also includes a locking element 534, which is located below the base 2; the locking element 534 is specifically a locking nut, and the bottom end of the connecting rod 4 passes through the through hole 21 and is threadedly connected to the locking element 534.

[0072] Once the connecting rod 4 has risen or fallen to the designated position, tightening the locking element 534 secures it firmly in place. This, combined with the threaded self-locking function of the threaded sleeve 52, creates a double-locking mechanism, further enhancing the stability of the connecting rod 4 during use. Even after prolonged use, when the threads between the threaded sleeve 52 and the connecting rod 4 may wear down, reducing the self-locking performance, the locking element 534 still provides reliable fixation, preventing the connecting rod 4 from rising or falling unexpectedly. When subjected to strong vibrations, impacts, or other external forces, the locking element 534 effectively resists these forces, ensuring that the multi-stage telescopic cover 3 and the bird spike protector 1 remain in their designated positions without shifting.

[0073] like Figure 6 and Figure 7 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0074] There are four connecting rods 4, arranged in pairs on both sides of the power tower. When the bird spike device is installed on the power tower, the bird spike body 1 is in a retracted state. At this time, the bottom end of the connecting rod 4 is located inside the through hole 21 and will not interfere with the power tower.

[0075] After the base 2 is fixed to the power tower, rotate the drive rod 51 to lower all the connecting rods 4, switch the bird spike body 1 to the use state, and then tighten the locking part 534 to the bottom of the corresponding connecting rod 4.

[0076] like Figures 3 to 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0077] The bottom of the bird spike body 1 is fixed with a lifting seat 6, which is slidably connected to the base 2. A lifting component 7 is provided between the lifting seat 6 and the linkage component 53.

[0078] When the linkage component 53 drives the screw sleeve 52 to rotate, so that the connecting rod 4 can be raised or lowered, the linkage component 53 also drives the lifting seat 6 to slide in the opposite direction to the connecting rod 4.

[0079] When in the storage state, the connecting rod 4 rises and drives the multi-stage telescopic cover 3 to unfold and retract the bird spike body 1. At the same time, the lifting seat 6 drives the bird spike body 1 to move downward, so that the bird spike body 1 can be more deeply wrapped by the multi-stage telescopic cover 3, which further improves the tightness of storage and the protective effect on the bird spike body 1, and reduces the storage space occupied.

[0080] When in use, the connecting rod 4 descends to fold the multi-stage telescopic cover 3, while the lifting seat 6 drives the bird spike body 1 to move upward, shortening the telescopic formation of the multi-stage telescopic cover 3, thereby reducing the number of rotations of the drive rod 51 and simplifying manual operation; it can also reduce the space occupied inside the device to a certain extent, making the structure more compact.

[0081] like Figure 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0082] The upper surface of the base 2 has a cavity 23 in the middle for the lifting seat 6 to slide into; the lifting assembly 7 includes a threaded ring 71 and a connecting toothed ring 72; the threaded ring 71 is rotatably connected in the cavity 23 and threadedly connected to the lifting seat 6; the connecting toothed ring 72 is coaxially fixed to the outside of the threaded ring 71 and meshes with all the linkage gears 532.

[0083] When the linkage gear 532 drives the screw sleeve 52 and the connecting gear ring 72 to rotate, the connecting rod 4 and the lifting seat 6 slide in opposite directions.

[0084] When the linkage gear 532 rotates, it drives the threaded ring 71 to rotate via the connecting gear ring 72. Since the threaded ring 71 is threadedly connected to the lifting seat 6, the rotation of the threaded ring 71 is converted into the lifting motion of the lifting seat 6. This allows the linkage assembly 53 to simultaneously drive the lifting seat 6 to move in the opposite direction while driving the connecting rod 4 to rise and fall, achieving efficient power transmission and coordinated action. The threaded connection between the threaded ring 71 and the lifting seat 6 has the characteristic of precise transmission, ensuring that the lifting distance of the lifting seat 6 is precisely controllable and that the extension and retraction coordination with the multi-stage telescopic cover 3 is more precise. The connecting gear ring 72 meshes with all the linkage gears 532, ensuring that the power of all the linkage gears 532 can be concentratedly transmitted to the threaded ring 71, making the rotation of the threaded ring 71 more stable and uniform, thereby ensuring the stability of the lifting seat 6's rise and fall.

[0085] like Figure 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0086] The lifting assembly 7 also includes two eccentric rods 73, which are vertically fixed on both sides inside the receiving cavity 23 and pass through the lifting seat 6.

[0087] During the lifting process of the lifting seat 6, the eccentric rod 73 restricts the rotation of the lifting seat 6, ensuring that the lifting seat 6 can only slide in the vertical direction. This prevents the lifting seat 6 from rotating under the drive of the threaded ring 71, thus ensuring the smoothness and straightness of the lifting seat 6's movement. At the same time, the eccentric rod 73 enhances the connection strength between the lifting seat 6 and the base 2, making the lifting seat 6 more stable when bearing the weight of the bird spike body 1 and external wind loads, thereby improving the structural strength and reliability of the entire device.

[0088] like Figure 2 and Figure 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0089] The first layer of the multi-level telescopic cover 3 is defined as the top cover 31; when the bird spike body 1 is in the retracted state, the top of the bird spike body 1 is folded into the inside of the top cover 31, and the inner diameter of the top cover 31 gradually increases from bottom to top.

[0090] The trumpet-shaped structural design allows the top of the bird spike body 1 to be more easily folded into or out of the top cover 31, avoiding jamming or collision between the spikes of the bird spike body 1 and the top cover 31, thus ensuring the smoothness of the storage and use process.

[0091] Furthermore, when storing the bird spike body 1, the flared end of the top cover 31 first contacts and squeezes the spikes on the bird spike body 1, and the constricted end of the bottom cover 31 further squeezes and retracts the spikes, thus enabling a gradual process of retracting the spikes.

[0092] like Figure 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0093] When the bird spike body 1 is in use, the top of each level of the multi-level telescopic cover 3 is stepped from the outside to the inside.

[0094] The stepped multi-level telescopic cover 3 surface can prevent birds from landing or nesting on it, so that the multi-level telescopic cover 3 can play a bird-proof role, and will not affect the workers' disassembly and assembly of the bird spike device.

[0095] like Figure 6 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0096] The base 2 is divided into upper and lower layers by the rotation axis of the drive rod 51. The through hole 21 and the annular groove 22 are formed between the upper and lower base 2. The two base 2 are detachably fixed by multiple connecting bolts 24. The connecting bolts 24 pass through the lower base 2 from below and are threaded to the upper base 2.

[0097] During production, the upper and lower base layers 2 can be processed separately and then assembled together, facilitating the installation, debugging, and maintenance of internal components such as the linkage component 53 and the screw sleeve 52. When the internal drive mechanism 5 or linkage component 53 malfunctions and requires repair, the two base layers 2 can be easily disassembled to access the internal components, reducing maintenance costs and workload. Furthermore, the detachable fixing method between the two base layers 2 makes the structure of the base 2 more flexible, allowing for the replacement of components of different specifications according to actual needs, thus improving the versatility and maintainability of the device.
