Description

Technical Field

[0001] This invention belongs to the field of power equipment protection technology, specifically relating to a needle-punching bird deterrent. Background Technology

[0002] Bird deterrents are specialized devices used to drive away birds and prevent them from disturbing the work environment or facilities. They are widely used in power lines, farmland, orchards, airport runways, and other scenarios. Their core principles are categorized into physical, acoustic, and optical types. Physical deterrents use spikes or baffles to block birds from landing; acoustic deterrents simulate the calls of birds of prey or use high-frequency ultrasonic waves; and optical deterrents use flashing bright light to interfere with birds' vision. Some even integrate multi-mode linkage functions. Among the physical types, the piercing bird deterrent is a specialized model adapted for the power industry. It emphasizes convenient installation and stable protection, directly fixing itself to the vicinity of power conductors and insulators through a piercing structure without the need for additional fasteners. Its highly efficient installation is achieved, and the dense spikes at the tip effectively prevent birds from landing and nesting, avoiding short circuits caused by bird droppings or nesting materials. It is weather-resistant and anti-aging, suitable for harsh outdoor conditions, and is a commonly used device for bird protection of power lines, precisely addressing the core hidden danger of bird intrusion in the power sector.

[0003] Since piercing bird deterrents work by deploying metal spikes, most existing bird deterrents are designed as a bundle of spikes for easy carrying by workers when installed on power equipment. This results in a limited range of protection when deployed, allowing some small birds to still nest between the bird deterrent and the power equipment. Furthermore, most existing bird deterrents are fixed structures and cannot be adjusted in real time at different junctions with the power equipment, further limiting their applicability. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a needle-type bird deterrent.

[0005] The technical solution adopted to solve the above technical problems is: a needle-type bird deterrent, including an installation and fixing mechanism, an adjustment support mechanism installed at the bottom of the inner wall of the installation and fixing mechanism, and a linkage needle mechanism rotatably connected to the adjustment support mechanism; An ejection support mechanism is provided between the top of the mounting and fixing mechanism and the bottom of the adjusting support mechanism. The ejection support mechanism is used to eject and deploy the linkage needle mechanism. The top of the ejection support mechanism is spirally connected to a locking and fixing mechanism, which is used to fix the ejection support mechanism. An auxiliary limiting mechanism is provided between the outer wall of the mounting and fixing mechanism and the linkage needle mechanism.

[0006] Furthermore, the mounting and fixing mechanism includes a hemispherical shell, the bottom of which is fixedly connected to a plurality of first bearings, and the bottom of the plurality of first bearings is rotatably connected to a perforated mounting plate.

[0007] The above technical solution allows the bird deterrent to be installed on power equipment using multiple multi-hole mounting plates, thus enabling the bird deterrent to be installed. Multiple first bearings allow for multi-angle installation of multiple multi-hole mounting plates, making it more adaptable.

[0008] Furthermore, the hemispherical shell has multiple arc-shaped through holes.

[0009] Through the above technical solution, the strip-shaped through hole is used for galvanized barbed needles to pass through, and to limit the movement of multiple galvanized barbed needles.

[0010] Furthermore, the adjusting support mechanism includes a fixed ring, with multiple limiting blocks fixedly connected to the outer bottom of the fixed ring, an integral extension ring fixedly connected to the inner top of the fixed ring, and multiple second bearings fixedly connected to the top of the integral extension ring.

[0011] The above technical solution provides support for the overall adjustment support mechanism and the linkage needle mechanism through the fixed ring, and achieves locking and fixing through the engagement of multiple limit blocks and the ejection support mechanism. The different heights of the integrated extension ring can be used to match different numbers of galvanized needles to change the protection area of ​​the galvanized needles. The linkage needle mechanism is rotated through multiple second shaft seats.

[0012] Furthermore, the linkage needle mechanism includes a first connecting ring, with multiple third shaft seats fixedly connected to the outer wall of the first connecting ring. A double-axis base is rotatably connected between each of the multiple third shaft seats and its corresponding second shaft seat. A galvanized needle is fixedly connected to the top of each of the multiple double-axis bases. A rotating telescopic connecting assembly is rotatably connected between the multiple double-axis bases between the third and second shaft seats. The rotating telescopic connecting assembly includes a rotating telescopic rod and a U-shaped rotating limit frame rotatably connected to the two double-axis bases. A convex shaft rod is fixedly connected to the other end of the rotating telescopic rod. A disposable plastic port protection plate is installed between the tops of the multiple galvanized needles. The disposable plastic port protection plate includes a multi-ring connecting plate, with a needle sleeve fixedly connected to the bottom of the multi-ring connecting plate. Multiple needle limit clamps are installed between the outer walls of the multiple galvanized needles.

[0013] With the above technical solution, during installation, workers remove the disposable plastic port protection plate from the linkage needle mechanism, exposing multiple galvanized needles neatly arranged under the constraint of multiple needle limit clamps. The neatly arranged galvanized needles are then inserted from the bottom of the hemispherical shell and emerge through multiple through holes. After the galvanized needle ports pass through the hemispherical shell, multiple needle limit clamps are removed, and the adjusting support mechanism is fully pushed into the interior of the hemispherical shell. Subsequently, the inserting and ejecting support mechanism is used. During insertion, multiple dual-axis bases and multiple rotating telescopic connecting components are continuously compressed, causing the rotating telescopic rods and U-shaped rotating limit frames in the multiple rotating telescopic connecting components to slide and lengthen relative to each other until the multiple rotating telescopic connecting components are stretched to their maximum length. At this point, the entire linkage needle mechanism is fully bent and unfolded, and the multiple galvanized needles unfold spherically, thus providing protection.

[0014] Furthermore, the ejection support mechanism includes a fixed round rod, an integral threaded rod is fixedly connected to the top of the fixed round rod, a support round shell is fixedly connected to the outer wall of the fixed round rod, and a cross-shaped limiting rod is fixedly connected to the bottom of the fixed round rod.

[0015] Through the above technical solution, the ejection support mechanism is removed, and the fixed round rod and the integrated threaded rod are inserted into the first connecting ring from the bottom. Then, they pass through the center of the top of the hemispherical shell, so that the integrated threaded rod extends out and is engaged with the cross limit rod and the corresponding limit round block, thereby achieving the support and fixation of the adjustment support mechanism. During the insertion process, the support round shell will continuously squeeze multiple dual-axis bases and multiple rotating telescopic connecting components, thereby fully unfolding multiple galvanized needles.

[0016] Furthermore, the locking and fixing mechanism includes a threaded sleeve that is helically connected to the top of the ejection support mechanism. An integral extension pressure ring is fixedly connected to the bottom of the outer wall of the threaded sleeve. Multiple manual protrusions are fixedly connected to the top of the outer wall of the threaded sleeve. A central needle is fixedly connected to the top center of the threaded sleeve.

[0017] Using the above technical solution, the locking and fixing mechanism is finally removed, and the manual protruding rod is rotated to fix the ejector support mechanism by spiraling on the integrated threaded rod through the threaded sleeve. The ejector support mechanism is then used to fix the adjusting support mechanism and the linkage needle mechanism.

[0018] Furthermore, the auxiliary limiting mechanism is a limiting metal wire assembly.

[0019] The above technical solution uses multiple metal wires in the limiting metal wire assembly to wrap around galvanized barbed needles at the same horizontal position, thereby achieving auxiliary fixation and increasing the support strength of the galvanized barbed needles. The limiting metal wire assembly not only reinforces the equipment but also effectively improves the overall installation speed. It is used for the protection of low-altitude power equipment and facilitates subsequent repairs.

[0020] Furthermore, the auxiliary limiting mechanism is a sealing limiting mechanism, which includes multiple annular sealing plates that fit against the outer wall of the mounting and fixing mechanism and a second connecting ring that is sleeved on the top of the ejection support mechanism. The annular sealing plates include multiple curved sealing plates, and an integral connecting rod is fixedly connected between the multiple curved sealing plates. Multiple arc-shaped extension rods are fixedly connected to the outer wall of the second connecting ring, and multiple limiting blocks are fixedly connected to the inner walls of the multiple arc-shaped extension rods.

[0021] With the above technical solution, when installing the sealing and limiting mechanism, before removing the multiple needle limiting clamps, multiple annular sealing plates need to be fitted between the neatly arranged galvanized needles. After removing the needle limiting clamps, when unfolding the multiple galvanized needles, multiple annular sealing plates need to be slid down onto the outer wall of the hemispherical shell simultaneously. When the multiple annular sealing plates and the outer wall of the hemispherical shell are completely in contact, the multiple galvanized needles can be fully unfolded. After unfolding, fine adjustments can be made to ensure that each galvanized needle is secured in the circular groove on the curved sealing plate. Subsequently, the curved sealing plate can be used to control the hemispherical shell. The strip-shaped through holes on the body are sealed. Before installing the locking and fixing mechanism, the second connecting ring is sleeved on the top of the ejector support mechanism. Multiple limiting blocks on the inner wall of the arc-shaped extension rod limit and support multiple integrated connecting rods, further reinforcing the sealing and limiting mechanism. The locking and fixing mechanism is then installed in the same way to complete the assembly of the entire device. By designing the sealing and limiting mechanism, it can not only support and reinforce multiple galvanized barbs, but also seal the gaps in the hemispherical shell to prevent bird droppings from falling into the bird deterrent. It has a long maintenance cycle and is suitable for the protective installation of high-altitude power equipment.

[0022] Furthermore, the specifications of the multiple annular sealing plates are different, and they can all cover the outer wall of the installation and fixing mechanism. Each of the multiple curved sealing plates has two circular grooves. The multiple limiting blocks on the inner wall of the arc-shaped extension rod and the integrated connecting rods in the multiple annular sealing plates correspond one-to-one.

[0023] Through the above technical solution, multiple annular sealing plates of different specifications can completely cover the surface of the installation and fixing mechanism, providing better protection. The circular grooves on the curved sealing plate are used to engage galvanized needles, while also making the gap between two annular sealing plates smaller. Multiple limiting blocks can limit the movement of the integrated connecting rod.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention designs an adjustable support mechanism, a linkage needle mechanism and an ejection support mechanism. During installation, different adjustable support mechanisms and linkage needle mechanisms can be selected according to the required protection area of ​​the installation position. Different power equipment can be flexibly adjusted to improve the applicability of the device. Through the overall assembly structure, while satisfying the flexible adjustment, the bird deterrent can achieve a large area protection function after installation, and can also be in a retracted state before installation, which is convenient for staff to carry. (2) The present invention designs a limiting metal wire assembly and a sealing limiting mechanism. When facing power equipment of different heights, due to the different difficulties in inspection and maintenance, different fixing mechanisms can be selected to assist in fixing the galvanized needles. By winding the galvanized needles at the same horizontal position through the limiting metal wire assembly, the support strength of the galvanized needles can be increased. The installation speed is fast and it is suitable for the protection installation of low-altitude power equipment. By completing the support and reinforcement of multiple galvanized needles through the sealing limiting mechanism, the gaps of the hemispherical shell can also be sealed to prevent bird droppings from falling into the bird deterrent. The maintenance cycle is long and it is suitable for the protection installation of high-altitude power equipment. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages 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 specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] Example 1:

[0029] like Figures 1-5 As shown, a needle-type bird deterrent in this embodiment includes an installation and fixing mechanism 1. The installation and fixing mechanism 1 includes a hemispherical shell 101. A plurality of first bearing seats 102 are fixedly connected to the bottom of the hemispherical shell 101. A perforated mounting plate 103 is rotatably connected to the bottom of the plurality of first bearing seats 102. The bird deterrent can be installed on the power equipment through the plurality of perforated mounting plates 103 to realize the installation of the bird deterrent. The plurality of first bearing seats 102 can realize multi-angle installation of the plurality of perforated mounting plates 103, which has a wider range of applications. A plurality of arc-shaped through holes are opened on the hemispherical shell 101. The strip-shaped through holes are used for galvanized barbed needles 304 to pass through and to limit the position of the plurality of galvanized barbed needles 304.

[0030] like Figures 1-7 As shown, an adjusting support mechanism 2 is installed on the bottom of the inner wall of the mounting and fixing mechanism 1. The adjusting support mechanism 2 includes a fixing ring 201. Multiple limiting blocks 202 are fixedly connected to the outer bottom of the fixing ring 201. An integrated extension ring 203 is fixedly connected to the inner top of the fixing ring 201. Multiple second bearings 204 are fixedly connected to the top of the integrated extension ring 203. The fixing ring 201 provides support for the overall adjusting support mechanism 2 and the linkage needle mechanism 3. The locking and fixing are achieved by the engagement of multiple limiting blocks 202 and the ejection support mechanism 4. The different heights of the integrated extension ring 203 can be used to match different numbers of galvanized needles 304 to change the protection area of ​​the galvanized needles 304. The rotational connection of the linkage needle mechanism 3 is achieved by multiple second bearings 204.

[0031] like Figures 1-11 and Figure 15As shown, a linkage needle mechanism 3 is rotatably connected to the adjusting support mechanism 2. The linkage needle mechanism 3 includes a first connecting ring 301. Multiple third shaft seats 302 are fixedly connected to the outer wall of the first connecting ring 301. A double-axis base 303 is rotatably connected between each of the multiple third shaft seats 302 and its corresponding second shaft seat 204. A galvanized needle 304 is fixedly connected to the top of each of the multiple double-axis bases 303. A rotating telescopic connecting assembly 3 is rotatably connected between each of the multiple double-axis bases 303 between the third shaft seats 302 and the second shaft seat 204. 05. The rotating telescopic connection assembly 305 includes a rotating telescopic rod 3051 and a U-shaped rotating limit frame 3052 rotatably connected to two dual-axis bases 303. A convex shaft rod 3053 is fixedly connected to the other end of the rotating telescopic rod 3051. A disposable plastic port protection plate 306 is installed between the tops of multiple galvanized barbed needles 304. The disposable plastic port protection plate 306 includes a multi-ring connecting plate 3061. A barbed needle sleeve 3062 is fixedly connected to the bottom of the multi-ring connecting plate 3061. The multiple galvanized barbed needles 304... Multiple needle-limiting clips 307 are installed between the outer walls. During installation, the worker pulls out the disposable plastic port protection plate 306 from the linkage needle mechanism 3, thus exposing multiple galvanized needles 304 neatly arranged under the limitation of the multiple needle-limiting clips 307. Then, the neatly arranged multiple galvanized needles 304 are inserted from the bottom of the hemispherical shell 101 and then pass through multiple through holes. After the ends of the galvanized needles 304 pass through the hemispherical shell 101, the multiple needle-limiting clips 307 are removed, and the adjusting support mechanism 2 is fully pushed in. Inside the hemispherical shell 101, the ejector support mechanism 4 is subsequently inserted. During the insertion process, it continuously squeezes multiple dual-axis bases 303 and multiple rotating telescopic connecting components 305, thereby causing the rotating telescopic rods 3051 and U-shaped rotating limiters 3052 in the multiple rotating telescopic connecting components 305 to slide and lengthen relative to each other until the multiple rotating telescopic connecting components 305 are stretched to their maximum length. At this time, the overall linkage needle mechanism 3 is fully bent and unfolded, and multiple galvanized needles 304 unfold in a spherical shape, thereby playing a protective role.

[0032] like Figures 1-14As shown, an ejection support mechanism 4 is provided between the top of the mounting and fixing mechanism 1 and the bottom of the adjusting support mechanism 2. The ejection support mechanism 4 is used to eject and unfold the linkage needle mechanism 3. The ejection support mechanism 4 includes a fixed round rod 401, an integral threaded rod 402 is fixedly connected to the top of the fixed round rod 401, a support round shell 403 is fixedly connected to the outer wall of the fixed round rod 401, and a cross limit rod 404 is fixedly connected to the bottom of the fixed round rod 401. The ejection support mechanism 4 is taken out, and the fixed round rod 401 and the integral threaded rod 402 are inserted into the first connecting ring 301 from the bottom, and then pass through the center of the top of the hemispherical shell 101, so that the integral threaded rod 402 extends out and engages with the corresponding limit block 202 through the cross limit rod 404, thereby achieving the support and fixation of the adjusting support mechanism 2. During the insertion process, the support round shell 403 will continuously squeeze multiple dual-axis bases 303 and multiple rotating telescopic connecting components 305, thereby fully unfolding multiple galvanized needles 304.

[0033] like Figures 1-14 As shown, the top of the ejector support mechanism 4 is helically connected to a locking and fixing mechanism 5. The locking and fixing mechanism 5 is used to fix the ejector support mechanism 4. The locking and fixing mechanism 5 includes a threaded sleeve 501 helically connected to the top of the ejector support mechanism 4. An integral extension pressure ring 502 is fixedly connected to the bottom of the outer wall of the threaded sleeve 501. Multiple manual protrusions 503 are fixedly connected to the top of the outer wall of the threaded sleeve 501. A central needle 504 is fixedly connected to the center of the top of the threaded sleeve 501. Finally, the locking and fixing mechanism 5 is removed, and the manual protrusions 503 are rotated so that the threaded sleeve 501 can be helically rotated on the integral threaded rod 402 to fix the ejector support mechanism 4. The ejector support mechanism 4 is used to fix the adjusting support mechanism 2 and the linkage needle mechanism 3.

[0034] like Figures 1-11 As shown, an auxiliary limiting mechanism 6 is provided between the outer wall of the mounting and fixing mechanism 1 and the linkage needle mechanism 3. The auxiliary limiting mechanism 6 is a limiting metal wire assembly 61. Multiple metal wires in the limiting metal wire assembly 61 are used to wrap around the galvanized needles 304 at the same horizontal position, thereby achieving auxiliary fixing and increasing the support strength of the galvanized needles 304. While reinforcing, the limiting metal wire assembly 61 can effectively improve the installation speed of the overall equipment, which is used for the protection of low-altitude power equipment and facilitates subsequent repairs.

[0035] Example 2:

[0036] like Figures 1-21As shown, the difference from Embodiment 1 is that the auxiliary limiting mechanism 6 is a sealing limiting mechanism 62. The sealing limiting mechanism 62 includes multiple annular sealing plates 621 that are attached to the outer wall of the mounting and fixing mechanism 1 and a second connecting ring 622 that is sleeved on the top of the ejection support mechanism 4. The annular sealing plates 621 include multiple curved sealing plates 6211, and each of the multiple curved sealing plates 6211 is fixedly connected with an integral connecting rod 6212. The outer wall of the second connecting ring 622 is fixedly connected with multiple arc-shaped extension rods 623, and the inner walls of the multiple arc-shaped extension rods 623 are fixedly connected with multiple limiting blocks 624. When installing the sealing limiting mechanism 62, it is necessary to remove multiple needles. Before the clamp 307 is removed, multiple annular sealing plates 621 are fitted between the neatly arranged galvanized barbed needles 304. After removing the barbed needle clamp 307, when unfolding the multiple galvanized barbed needles 304, the multiple annular sealing plates 621 need to be slid down onto the outer wall of the hemispherical shell 101 simultaneously. When the multiple annular sealing plates 621 and the outer wall of the hemispherical shell 101 are completely in contact, the multiple galvanized barbed needles 304 can be fully unfolded. After unfolding, fine adjustments can be made to ensure that each galvanized barbed needle 304 is properly positioned in the circular groove on the curved sealing plate 6211. Subsequently, the curved sealing plate 6211 can be used to seal the strip-shaped through holes on the hemispherical shell 101. Simultaneously, before installing the locking and fixing mechanism 5, the second connecting ring 622 is sleeved on the top of the ejector support mechanism 4, and multiple limiting blocks 624 on the inner wall of the arc-shaped extension rod 623 provide limiting support for multiple integrated connecting rods 6212, further reinforcing the sealing and limiting mechanism 62. The locking and fixing mechanism 5 is then installed in the same manner to complete the assembly of the entire device. By designing the sealing and limiting mechanism 62, while supporting and reinforcing multiple galvanized barbed needles 304, it can also seal the gaps in the hemispherical shell 101, preventing bird droppings from falling into the bird deterrent. It has a long maintenance cycle and is suitable for the protective installation of high-altitude electrical equipment. Multiple annular sealing plates 62... The specifications of the multiple curved sealing plates 6211 are all different, and they can all cover the outer wall of the installation and fixing mechanism 1. Two circular grooves are opened on each of the multiple curved sealing plates 6211. The multiple limiting blocks 624 on the inner wall of the arc-shaped extension rod 623 correspond one-to-one with the integrated connecting rods 6212 in the multiple annular sealing plates 621. The multiple annular sealing plates 621 with different specifications can completely cover the surface of the installation and fixing mechanism 1, and play a better protective role. The circular grooves opened on the curved sealing plates 6211 are used to engage the galvanized needles 304, and at the same time make the gap between the two annular sealing plates 621 smaller. The multiple limiting blocks 624 can play a limiting role for the integrated connecting rods 6212.

[0037] The working principle of this embodiment is as follows: During installation, different adjustment support mechanisms 2 and linkage needle mechanisms 3 are selected according to the required protection area of ​​the installation location, such as... Figure 16 The number of galvanized 304 barbed wire needles in the sample is less than Figure 15 And then, as Figure 16 After unfolding ( Figure 17 The coverage area of ​​a galvanized 304 barbed wire needle will be smaller than that of a galvanized barbed wire Figure 1 After confirmation, the worker pulls out the disposable plastic port protection plate 306 from the linkage needle mechanism 3, thereby exposing the multiple galvanized needles 304 neatly arranged under the limit of multiple needle limit clamps 307. Then, the multiple galvanized needles 304 are inserted from the bottom of the hemispherical shell 101 and then pass through multiple through holes. After the galvanized needles 304 have passed through the hemispherical shell 101, the multiple needle limit clamps 307 are removed, and the adjusting support mechanism 2 is fully pushed into the interior of the hemispherical shell 101. Then, the ejection support mechanism 4 is removed, and the fixed round rod 401 and the integrated threaded rod 402 are inserted into the first connecting ring 301 from the bottom. Then, they pass through the center of the top of the hemispherical shell 101, so that the integrated threaded rod 402 extends out and is engaged with the corresponding limiting round block 202 through the cross limiting rod 404. During this process, the support shell 403 continuously squeezes the multiple dual-axis bases 303 and multiple rotating telescopic connecting components 305, thereby causing the rotating telescopic rod 3051 and the U-shaped rotating limiting frame 3052 in the multiple rotating telescopic connecting components 305 to slide and lengthen relative to each other until the multiple rotating telescopic connecting components 305 are stretched to their maximum length. At this time, the overall linkage needle mechanism 3 is fully bent and unfolded, and the multiple galvanized needles 304 are unfolded in a spherical shape. Finally, the locking and fixing mechanism 5 is removed, and the manual protrusion rod 503 is rotated and then the threaded sleeve 501 is spirally rotated on the integrated threaded rod 402 to fix the ejection support mechanism 4. The ejection support mechanism 4 is used to fix the adjustment support mechanism 2 and the linkage needle mechanism 3. Finally, the auxiliary limiting mechanism 6 is used to fix the multiple galvanized barbed needles 304, and then the bird deterrent is installed on the power equipment by the multiple perforated mounting plates 103 at the bottom of the mounting and fixing mechanism 1.
