Description

Technical Field

[0001] This invention belongs to the technical field of power facility protection, and more specifically, relates to a bird spike structure that is easy to assemble and disassemble. 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] Currently available bird spikes include a C-shaped base for fixing to power towers, a coiled tube fixed to the base, and multiple spikes fixedly inserted into the coiled tube.

[0004] Since the bottom of the spike and the converging tube are fixed at once, if some spikes are broken or damaged by external factors, affecting normal use, the entire bird spike needs to be replaced, resulting in high maintenance costs for the bird spike. Summary of the Invention

[0005] The purpose of this invention is to provide a bird spike structure that is easy to disassemble and assemble, in order to solve the technical problem in the prior art that if part of the spike is broken or damaged by external factors, affecting normal use, the entire bird spike needs to be replaced, resulting in high maintenance costs for bird spikes.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a bird spike structure that is easy to assemble and disassemble, comprising:

[0007] Base for mounting onto power towers;

[0008] The mounting plate is fixed on the base. The upper surface of the mounting plate has multiple sets of circumferentially distributed mounting grooves along its radial direction. Each set of mounting grooves has a set of positioning grooves on the same side.

[0009] Multiple sets of needles, each set of needles corresponding to each set of mounting slots, and a bottom post fixed to the bottom of each needle for insertion into the mounting slot;

[0010] Multiple sets of positioning strips, each corresponding to a positioning groove in the set and sliding within it; and

[0011] A lever is slidably connected to the outside of the mounting plate, and a linkage mechanism is provided between the lever and all the positioning strips;

[0012] The bottom post has an annular groove on its outer side, and the positioning strip is used to insert into the annular groove. The linkage mechanism is located inside the mounting plate. When the paddle slides, the linkage mechanism drives all the positioning strips to simultaneously insert into or disengage from the corresponding annular groove.

[0013] In one possible implementation, based on the above technical solutions, the linkage mechanism includes:

[0014] Multiple rotating rings, each corresponding to one of the positioning strips, are coaxially rotatably connected inside the mounting plate. The inner circumferential surface of each rotating ring is used to fix the positioning strip.

[0015] At least one set of linkage components is disposed inside the mounting plate and acts between two adjacent rotating rings;

[0016] The mounting plate has a sliding hole on its outer circumference for the paddle to slide inside, and the paddle is fixed to the outermost rotating ring. The two adjacent sets of positioning grooves are opened in opposite directions on the mounting groove. When the paddle drives the outermost rotating ring to rotate, the linkage component drives the adjacent rotating ring to rotate in the opposite direction.

[0017] In one possible implementation, based on the above technical solutions, the mounting plate has multiple receiving cavities, with one receiving cavity between each adjacent rotating ring; the linkage component includes:

[0018] Two rotating shafts are vertically rotatably connected at both ends within the same receiving cavity;

[0019] Two arc-shaped racks correspond one-to-one with the rotating shaft and are coaxially fixed on the side of the adjacent rotating ring facing the receiving cavity;

[0020] Two linked gears correspond one-to-one with and mesh with the arc-shaped rack, and the linked gears are coaxially fixed to the corresponding rotating shafts; and

[0021] A transmission component is disposed between the two rotating shafts and is used to drive the two rotating shafts to rotate in the same direction.

[0022] In one possible implementation, based on the above technical solutions, the transmission component includes:

[0023] Two sprockets, each corresponding to a shaft and coaxially fixed; and

[0024] A chain is fitted and engaged on the two sprockets.

[0025] In one possible implementation, based on the above technical solutions, the diameter of the sprocket near the outer side of the mounting plate is larger than the diameter of the sprocket near the inner side of the mounting plate.

[0026] In one possible implementation, based on the above technical solutions, a rotating plate is hinged to the outer end of the paddle, and limit grooves are provided on both sides of the outer opening of the sliding hole.

[0027] When the paddle is located at different ends of the sliding hole, the positioning strip and the annular groove are in an inserted or disengaged state, and the end of the rotating plate away from the paddle rotates into the limiting groove and closes the opening of the sliding hole.

[0028] In one possible implementation, based on the above technical solutions, an elastic strip is provided on the inner bottom wall of the sliding hole, and the upper surface of the elastic strip is a wavy surface; a limiting strip is fixed at the bottom of the paddle, and the limiting strip contacts the trough of the wavy surface.

[0029] In one possible implementation, based on the above technical solutions, both sides of the rotating plate are fixed with protrusions. When the outer end of the rotating plate rotates into the limiting groove, the protrusion on one side of the rotating plate is inserted between adjacent wave crests of the wave surface.

[0030] In one possible implementation, based on the above technical solutions, the height of the positioning strip gradually increases in the direction away from the annular slot.

[0031] In one possible implementation, based on the above technical solutions, the mounting plate is divided into two layers along the horizontal plane, and the two layers of the mounting plate are detachably connected; the receiving cavity is formed between the two layers of the mounting plate.

[0032] The beneficial effects of the bird spike structure provided by this invention, which is easy to assemble and disassemble, are as follows: Compared with the prior art, this invention, through the positioning groove and corresponding positioning strip opened on the same side of each set of mounting slots, cooperates with the annular groove on the outer side of the base post to accurately and firmly fix the spikes; when it is necessary to replace a damaged spike, by pushing the lever, the linkage mechanism can drive the positioning strip to disengage from the annular groove, realizing the quick disassembly and replacement of the spike, allowing the base and mounting seat to be reused, greatly reducing the maintenance cost of the bird spikes; and by simply sliding the lever, all positioning strips can be simultaneously inserted into or disengaged from the corresponding annular groove, realizing the unified installation or disassembly of the spikes, improving work efficiency and reducing maintenance time and labor costs.

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. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] It should be further noted that the accompanying drawings and embodiments of the present invention mainly describe the concept of the present invention. Based on this concept, some specific forms and arrangements of connection relationships, positional relationships, power mechanisms, power supply systems and control systems may not be fully described. 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.

[0050] 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. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0051] The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself. The terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0052] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. 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.

[0053] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, and "several" means one or more, unless otherwise explicitly specified.

[0054] The present invention will now describe a bird spike protection structure that is easy to assemble and disassemble.

[0055] like Figures 1 to 3 As shown, one embodiment of the present invention provides a bird spike structure that is easy to assemble and disassemble, including a base 1, a mounting plate 2, multiple sets of spikes 3, multiple sets of positioning strips 4, and a lever 5. The base 1 is used to install onto a power tower pole; the mounting plate 2 is fixed on the base 1, and multiple sets of circumferentially distributed mounting grooves 21 are formed on the upper surface of the mounting plate 2 along its radial direction. Each set of mounting grooves 21 has a set of positioning grooves 22 on the same side; each set of spikes 3 corresponds to each set of mounting grooves 21, and the bottom of the spikes 3 is fixed with a bottom post 31 for insertion into the mounting groove 21; the multiple sets of positioning strips 4 correspond to each set of positioning grooves 22 and slide inside; the lever 5 is slidably connected to the outside of the mounting plate 2, and a linkage mechanism 6 is provided between the lever 5 and all the positioning strips 4.

[0056] The bottom post 31 has an annular groove 311 on its outer side, and the positioning strip 4 is used to insert into the annular groove 311. The linkage mechanism 6 is set inside the mounting plate 2. When the paddle 5 slides, the linkage mechanism 6 drives all the positioning strips 4 to simultaneously insert into or disengage from the corresponding annular groove 311.

[0057] This embodiment provides an easy-to-disassemble bird spike structure. Compared with the prior art, when installing the spikes 3, the bottom post 31 of each spike 3 is inserted into the corresponding mounting groove 21. By pushing the lever 5, the linkage mechanism 6 can simultaneously drive all the positioning strips 4 into the corresponding annular slots 311, thereby fixing all the spikes 3.

[0058] When a damaged spike 3 needs to be replaced, by pushing the lever 5, the linkage mechanism 6 can drive the positioning strip 4 to disengage from the annular slot 311, realizing the quick disassembly and replacement of the spike 3, so that the base 1 and the mounting seat can be reused, greatly reducing the maintenance cost of the bird spikes; and by simply sliding the lever 5, all positioning strips 4 can be simultaneously inserted into or disengaged from the corresponding annular slot 311, realizing the unified installation or disassembly of the spike 3, improving work efficiency and reducing maintenance time and labor costs.

[0059] like Figures 2 to 3As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0060] The linkage mechanism 6 includes multiple rotating rings 61 and at least one set of linkage components 62; the multiple rotating rings 61 correspond one-to-one with each set of positioning strips 4, the rotating rings 61 are coaxially rotatably connected inside the mounting plate 2, and the inner circumferential surface of the rotating rings 61 is used to fix the positioning strips 4; the linkage components 62 are disposed inside the mounting plate 2 and act between two adjacent rotating rings 61.

[0061] Among them, the outer peripheral surface of the mounting plate 2 is provided with a sliding hole 23 for the paddle 5 to slide inside, and the paddle 5 is fixed to the outermost rotating ring 61; the two adjacent sets of positioning grooves 22 are opened in opposite directions on the mounting groove 21, that is, the positioning strips 4 on the adjacent rotating rings 61 face opposite directions; when the paddle 5 drives the outermost rotating ring 61 to rotate, the linkage component 62 drives the adjacent rotating rings 61 to rotate in the opposite direction.

[0062] When the paddle 5 drives the outermost rotating ring 61 to rotate, the linkage component 62 can drive the adjacent rotating ring 61 to rotate in the opposite direction. The rotating ring 61 drives the positioning strip 4 to accurately insert or disengage from the annular slot 311, making the movement of the positioning strip 4 more stable and precise, ensuring the smooth installation and disassembly of the needle 3, and enabling the entire linkage mechanism 6 to achieve the coordinated action of multiple positioning strips 4, ensuring the synchronicity and consistency of the installation and disassembly of the needle 3.

[0063] like Figures 3 to 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0064] The mounting plate 2 has multiple receiving cavities 24, with one receiving cavity 24 between each adjacent rotating ring 61; the linkage assembly 62 includes two rotating shafts 621, two arc-shaped racks 622, two linkage gears 623, and a set of transmission components 624; the two rotating shafts 621 are vertically rotatably connected to both ends within the same receiving cavity 24; the two arc-shaped racks 622 correspond one-to-one with the rotating shafts 621 and are coaxially fixed on the side of the adjacent rotating ring 61 facing the receiving cavity 24; the two linkage gears 623 correspond one-to-one with the arc-shaped racks 622 and mesh with them, and the linkage gears 623 are coaxially fixed with the corresponding rotating shafts 621; the transmission component 624 is disposed between the two rotating shafts 621 and is used to drive the two rotating shafts 621 to rotate in the same direction.

[0065] Multiple accommodating cavities 24 provide suitable installation space for the linkage assembly 62, making the entire linkage mechanism 6 more compact and rational in structure. When the rotating ring 61 rotates, the arc-shaped rack 622 can drive the linkage gear 623 to rotate, realizing the transmission of power. The linkage gear 623 rotates synchronously with the corresponding rotating shaft 621, and drives another rotating shaft 621 to rotate in the same direction through the transmission component 624. The linkage gear 623 on the other rotating shaft 621 drives the adjacent arc-shaped rack 622 and rotating ring 61 to rotate, realizing the opposite rotation between two adjacent rotating rings 61. It can accurately control the rotation direction and angle of adjacent rotating rings 61, thereby ensuring that the positioning strip 4 can be accurately inserted into or disengaged from the annular slot 311, further improving the installation and disassembly accuracy of the bird spike structure.

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

[0067] The transmission component 624 includes two sprockets 6241 and a chain 6242; the two sprockets 6241 correspond one-to-one with the rotating shaft 621 and are fixed coaxially; the chain 6242 is sleeved and engaged on the two sprockets 6241.

[0068] The cooperation between sprocket 6241 and chain 6242 can stably transmit power, ensuring that the two rotating shafts 621 can rotate in the same direction, thereby ensuring the coordinated action of adjacent rotating rings 61. Compared with other transmission methods, chain drive is not limited by distance and can achieve efficient power transmission within the limited space inside the mounting plate 2, making the operation of the linkage mechanism 6 more stable and reliable. At the same time, chain drive has good wear resistance and fatigue resistance, reducing the frequency of maintenance and replacement, and lowering the cost of use.

[0069] like Figure 4 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0070] The diameter of the sprocket 6241 near the outer side of the mounting plate 2 is larger than the diameter of the sprocket 6241 near the inner side of the mounting plate 2.

[0071] Since the diameter of the rotating ring 61 gradually decreases from the outside to the inside, in order to match the rotation angle of the inner rotating ring 61 with the rotation angle of the outer rotating ring 61, sprockets 6241 of different diameters are set to achieve variable speed transmission. When the larger diameter sprocket 6241 rotates, it can drive the smaller diameter sprocket 6241 to rotate faster, thereby matching the rotation angle of the inner rotating ring 61 with the angle of the outer rotating ring 61, and realizing the precise movement of all positioning bars 4.

[0072] like Figure 5 and Figure 6As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0073] A rotating plate 51 is hinged to the outer end of the paddle 5, and limiting grooves 25 are provided on both sides of the outer opening of the sliding hole 23. When the paddle 5 is located at different ends of the sliding hole 23, the positioning strip 4 and the annular groove 311 are in the insertion or disengagement state, and the end of the rotating plate 51 away from the paddle 5 rotates into the limiting groove 25 and closes the opening of the sliding hole 23.

[0074] When the paddle 5 is pushed to either end of the sliding hole 23, the outer end of the rotating plate 51 can rotate into the corresponding limiting groove 25, thereby closing the opening of the sliding hole 23 and preventing foreign objects from entering the sliding hole 23, thus ensuring the stable operation of the subsequent linkage mechanism 6. Furthermore, when it is necessary to push the paddle 5, the movement of the paddle 5 can be achieved by pulling the rotating plate 51, which increases the hand contact area for the operator and makes it easier to operate.

[0075] like Figures 5 to 6 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0076] An elastic strip 231 is provided on the inner bottom wall of the sliding hole 23, and the upper surface of the elastic strip 231 is a wavy surface; a limiting strip 52 is fixed at the bottom of the paddle 5, and the limiting strip 52 contacts the trough of the wavy surface.

[0077] The wavy surface of the elastic strip 231 can provide multiple stable stopping positions for the paddle 5. When the paddle 5 slides, the limiting strip 52 contacts the trough of the wavy surface, so that the paddle 5 can stay stably in a specific position, preventing the paddle 5 from sliding randomly due to external force, ensuring that the positioning strip 4 and the annular groove 311 maintain a stable insertion or disengagement state, and increasing the stability and reliability of the paddle 5 operation.

[0078] like Figures 5 to 6 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0079] Both sides of the rotating plate 51 are fixed with protrusions 511. When the outer end of the rotating plate 51 is rotated into the limiting groove 25, the protrusion 511 on one side of the rotating plate 51 is inserted between the adjacent wave crests of the wave surface.

[0080] The insertion of the protrusion 511 provides additional limiting function, preventing the rotating plate 51 from easily rotating or disengaging from the limiting groove 25 when subjected to external force, ensuring that the opening of the sliding hole 23 is always closed, and better protecting the linkage mechanism 6 inside the mounting plate 2. At the same time, the protrusion 511 on the other side of the rotating plate 51 faces outward, making it convenient for operators to rotate the rotating plate 51 outward.

[0081] Based on the above embodiments, the present invention provides another specific embodiment as follows:

[0082] The height of the positioning strip 4 gradually increases in the direction away from the annular groove 311.

[0083] After the positioning strip 4 is inserted into the annular groove 311, this height change can increase the contact area and friction between the positioning strip 4 and the annular groove 311, making the installation of the spike 3 more secure and less prone to loosening; when subjected to external force, the positioning strip 4 can better withstand the pressure and maintain the stability of the spike 3, further improving the protective performance and reliability of the bird spike structure.

[0084] like Figure 1 As shown, based on the above embodiments, the present invention provides another specific embodiment as follows:

[0085] The mounting plate 2 is divided into two layers along the horizontal plane, and the two layers of mounting plates 2 are detachably connected; the receiving cavity 24 is formed between the two layers of mounting plates 2.

[0086] The detachable two-layer mounting plates 2 facilitate the installation of internal structures such as the linkage component 62. Workers can first install the linkage component 62 and other components on one layer of mounting plate 2, and then assemble them with the other layer, improving assembly efficiency and accuracy. Furthermore, when the linkage component 62 malfunctions or requires maintenance, both layers of mounting plates 2 can be easily disassembled for inspection and replacement of internal components. This also facilitates cleaning and maintenance of the interior of the mounting plates 2, maintaining the linkage mechanism 6 in good working order and extending the service life of the bird spike protection structure.

[0087] Specifically, multiple bolts are distributed circumferentially between the two mounting plates 2, and the bolts are threaded to the lower mounting plate 2 after passing through the upper mounting plate 2.

[0088] Multiple bolts are evenly distributed on the connecting surface of mounting plate 2, ensuring a tight fit between the two layers of mounting plate 2. This uniform force distribution avoids localized stress concentration, guaranteeing the stability and reliability of the entire mounting plate 2 structure. Tightening the bolts is relatively simple; workers only need to use appropriate tools to tighten the bolts to the required torque to complete the assembly of mounting plate 2. This not only improves installation efficiency but also reduces the skill requirements for installers, making the installation work more convenient and efficient.

[0089] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0090] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.
