Description

Technical Field

[0001] This invention relates to the field of bird spikes, specifically a spacer-type bird spike for power transmission lines. Background Technology

[0002] With the continuous development of the power system, power facilities such as overhead transmission lines and substations have been gradually improved and their coverage has become increasingly wider. However, in sparsely populated areas, birds are more active, and many birds use iron towers and complex substations as habitats. Bird nests, bird droppings, and other foreign objects interfere with the normal operation of power facilities, thus causing malfunctions.

[0003] To prevent birds from roosting and nesting on power equipment such as transmission towers and substations, current technology typically involves installing bird-proofing devices such as bird spikes. However, these devices are usually mounted on the tower itself, which is effective in preventing birds from moving within the protected area above the suspension insulator strings. But for tension transmission towers, where the insulator strings are installed laterally, these devices cannot be installed above the transverse insulators, thus failing to prevent birds from moving above the transverse insulator strings.

[0004] Above the transverse insulators of tension towers, there are usually transmission lines such as conductors and ground wires. When birds perch on these conductors and ground wires, their droppings are likely to fall on the transverse insulators below. The acidic components of the bird droppings will corrode the surface of the insulators, reduce their insulation performance, and affect the stability of the power supply. Summary of the Invention

[0005] To address the problem of birds easily landing on some power transmission lines in the prior art, this invention provides a space-occupying bird spike for power transmission lines.

[0006] To achieve the above objectives, the specific solution adopted by the present invention is as follows: a space-occupying bird spike for transmission lines, comprising a support plate, multiple basic spikes disposed on the support plate and at least one functional spike, wherein the functional spike comprises an installation cylinder and a spike rod, a receiving cylinder and a spike portion that can be connected in sequence, the installation cylinder is fixed on the support plate, and one end of the spike rod is provided with a base with a diameter smaller than the inner diameter of the installation cylinder, and the diameter of the base is larger than the diameter of the spike rod.

[0007] The container is filled with bird repellent paste and has an air vent on its side wall. An adjusting cylinder is fitted over the container to block the air vent. The inner surface of the adjusting cylinder is provided with an internal thread that matches the external thread on the outer wall of the container, and the outer surface is provided with an external thread that matches the internal thread on the inner wall of the mounting cylinder.

[0008] As a further optimization of the above technical solution: the top wall of the receiving cylinder is provided with an outwardly extending first connecting section, and the spike is provided with a connecting groove that matches the first connecting section.

[0009] As a further optimization of the above technical solution: the first connecting section is a cylinder with external threads on its surface, and the connecting groove is provided with internal threads that are compatible with the external threads on the first connecting section.

[0010] As a further optimization of the above technical solution: the spike rod and the receiving cylinder are connected by a connecting cylinder. The two ends of the connecting cylinder are open, and a baffle is radially arranged inside the connecting cylinder. The baffle has a through hole and a rubber plug is placed in the through hole.

[0011] As a further optimization of the above technical solution: a cross-shaped cutting edge is provided on the rubber stopper.

[0012] As a further optimization of the above technical solution: the bottom of the receiving cylinder is open and is provided with a second connecting section extending outward, the second connecting section can be inserted into one end of the connecting cylinder and threadedly connected to the connecting cylinder; the other end of the connecting cylinder is for the spike rod to be inserted and threadedly connected to the spike rod.

[0013] As a further optimization of the above technical solution: the support plate is provided with multiple needle-punched mounting holes. The basic needle punch includes a limiting part, a mounting part and a tapered part connected in sequence. The mounting part is located inside the needle-punched mounting hole. The diameter of the large-diameter end of the tapered part and the diameter of the limiting part are both larger than the diameter of the needle-punched mounting hole.

[0014] As a further optimization of the above technical solution: the bearing plate is a flexible plate with multiple fasteners on it to fix the bearing plate to the power transmission line or to splice the bearing plates together.

[0015] As a further optimization of the above technical solution: the support plate is provided with fastening holes, and the fastening holes and fasteners are symmetrically arranged on the edge of the support plate.

[0016] As a further optimization of the above technical solution: the basic needle punch includes long needle punches and short needle punches, which are staggered on the support plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention prevents birds from landing on the transmission line by installing a support plate on the transmission line, thus avoiding the problem of birds landing on the conductor above the transverse insulator of the tension tower and causing bird droppings to drip onto the transverse insulator below and contaminate the insulator.

[0019] This invention cleverly incorporates bird repellent paste within the needle and uses an adjusting cylinder. Initially, the adjusting cylinder is screwed onto the outside of the receiving cylinder, concealing the through-hole and effectively preventing the bird repellent paste from leaking out before assembly. The adjusting cylinder can be detached from the receiving cylinder by rotation and moved down into the mounting cylinder on the support plate. Inside the mounting cylinder, it rotates and moves downwards, pressing against the base of the needle rod, thus securing the entire bird-repellent needle. At this point, the through-hole is no longer concealed, and the bird repellent paste can slowly and normally leak out. The adjusting cylinder serves both as a temporary concealment of the leak hole and as a fastener, completing the fixation of the entire functional needle. Attached Figure Description

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of the present invention should be understood as prior art known or should be known by those skilled in the art.

[0033] like Figure 1 , 5 As shown, this invention discloses a spacer-type bird spike for power transmission lines, comprising a support plate 1, multiple basic spikes 10 disposed on the support plate 1, and at least one functional spike. In use, the support plate 1 is fixed to the power transmission line. The basic spikes 10 and the functional spikes on the support plate 1 prevent birds from landing on the power transmission line, thereby preventing bird droppings from falling onto the power equipment below and causing pollution.

[0034] Specifically, the support plate 1 is a long strip plate injection molded from insulating material, and the functional needles and basic needles 10 are both located on the same side of the support plate 1. For example... Figure 1 , 2 As shown in Figure 4, the functional needle includes an installation cylinder 2 and a needle rod 3, a receiving cylinder 7, and a needle tip 6 that can be connected in sequence. After assembly, the needle rod 3, the receiving cylinder 7, and the needle tip 6 are connected in sequence and coaxially distributed.

[0035] The container 7 is a closed-top, open-bottom cylinder with its internal cavity opening downwards. Bird repellent paste is placed inside the cavity, and the side wall of the container 7 has an vent hole 702. The odor emitted by the bird repellent paste is released through the vent hole 702 to repel birds. The bird repellent paste is a commercially available product, or it can be prepared using the methods disclosed in Chinese invention patents with application numbers CN202210840542.4 and CN201410527780.5.

[0036] The receiving cylinder 7 is fitted with an adjusting cylinder 5 that can block the vent hole 702. The inner surface of the adjusting cylinder 5 is provided with an internal thread that matches the external thread on the outer wall of the receiving cylinder 7. Rotating the adjusting cylinder 5 can cause axial relative movement between it and the receiving cylinder 7, so that the adjusting cylinder 5 is separated from the receiving cylinder 7. The outer surface of the adjusting cylinder 5 is provided with an external thread that matches the internal thread on the inner wall of the mounting cylinder 2. Rotating the adjusting cylinder 5 can cause axial relative movement between it and the mounting cylinder 2, so that the adjusting cylinder 5 moves in and out of the mounting cylinder 2.

[0037] The top wall of the receiving cylinder 7 is provided with an upwardly extending first connecting section 701. The first connecting section 701 is cylindrical and has external threads on its outer wall. The spike 6 is a conical solid structure. The large-diameter end of the spike 6 is provided with a connecting groove 601 that matches the first connecting section 701. The inner side of the connecting groove 601 is provided with an internal thread that matches the external thread on the first connecting section 701. By rotating the spike 6 or the receiving cylinder 7, the spike 6 and the receiving cylinder 7 can be rotated relative to each other, thereby connecting the two threadedly.

[0038] The bottom of the receiving cylinder 7 is provided with a downwardly extending second connecting section 703, which is a cylindrical section coaxial with the receiving cylinder 7. Figure 3 As shown, the spiked rod portion 3 and the receiving cylinder 7 are connected by a connecting cylinder 4. The connecting cylinder 4 is open at both ends, and its inner wall is provided with internal threads. A baffle 8 is transversely arranged inside the connecting cylinder 4 to divide it into an upper connecting section and a lower connecting section. The diameter of the second connecting section 703 is smaller than the diameter of the receiving cylinder 7 and slightly smaller than the inner diameter of the connecting cylinder, so that the second connecting section 703 can be inserted into the upper connecting section of the connecting cylinder 4. The outer surface of the second connecting section 703 is provided with external threads that match the internal threads on the connecting cylinder 4, thereby achieving a threaded connection between the receiving cylinder 7 and the connecting cylinder 4.

[0039] The baffle 8 has a through hole, and a rubber plug 9 is placed inside the through hole to cover it. The rubber plug 9 is fixed inside the through hole by interference fit or by adhesive. The baffle 8 is made of metal, which has strong rigidity to facilitate the holding of bird repellent paste, and can also limit the distance that the spiked rod 3 and the second connecting section 703 extend into the connecting cylinder 4. The rubber plug 9 can be inserted by an injection molding machine to inject bird repellent paste into the receiving cylinder 7.

[0040] To facilitate the insertion of the bird repellent paste into the container, the rubber stopper 9 has a cross-shaped cutting edge. The rubber material has a certain degree of resilience, and the cross-shaped cutting edge facilitates the insertion of the syringe and can be reset after the syringe is withdrawn to prevent the bird repellent paste from flowing out of the cross-shaped cutting edge.

[0041] In other embodiments of the present invention, the rubber stopper 9 may also be a thin plate or sheet of rubber material, with a diameter larger than the diameter of the through hole on the baffle 8, and is fixed to the baffle 8 by adhesive bonding to cover the through hole.

[0042] The lower connecting section of the connecting cylinder 4 is detachably connected to the spike rod portion 3. The spike rod includes a spike rod base 302, a base 301 disposed at the lower end of the spike rod base 302, and a threaded section 303 disposed at the upper end of the spike rod base 302. The threaded section 303 has an external thread that matches the internal thread of the lower connecting section of the connecting cylinder 4. The threaded section 303 can be screwed into the lower connecting section of the connecting cylinder 4, and the connecting cylinder 4 is detachably connected by a threaded connection.

[0043] The mounting cylinder 2 is an open cylinder at both ends, with its lower end fixed to the support plate 1. Existing fixing methods such as bonding or welding are acceptable. The spike rod 3 is a solid cylindrical rod with a base 301 located at its lower end. The base 301 is cylindrical and coaxially arranged with the spike rod 3. The diameter of the base 301 is larger than the diameter of the spike rod 3 but smaller than the inner diameter of the mounting cylinder 2, and the thickness of the base 301 is smaller than the height of the mounting cylinder 2, allowing the base 301 to be inserted into the mounting cylinder 2. Rotating the adjusting cylinder 5 allows it to disengage from the receiving cylinder 7 and move downwards. Moving the adjusting cylinder 5 to the mounting cylinder 2 and threadedly connecting it inside the mounting cylinder 2, rotating and moving it downwards within the mounting cylinder 2, presses the base 301 firmly onto the support plate 1.

[0044] This invention cleverly incorporates bird repellent paste within the functional needle. An adjusting cylinder 5, initially screwed onto the outside of the receiving cylinder 7, completely conceals the vent hole, ensuring the bird repellent paste does not overflow or leak before assembly, thus maintaining its effectiveness. The adjusting cylinder 5 can be easily detached from the receiving cylinder 7 by rotating and moved down into the mounting cylinder 2 on the support plate 1. Within the mounting cylinder 2, it rotates and moves down, tightly pressing against the base 301 of the needle rod 3, achieving a stable and secure installation of the entire bird repellent needle. At this point, the vent hole is no longer concealed, allowing the bird repellent paste to escape normally and slowly, continuously exerting its bird-repelling effect. The adjusting cylinder 5 not only temporarily conceals the vent hole, protecting the bird repellent paste, but also functions as a fastener, securing the entire functional needle and ensuring its long-term effectiveness and stability.

[0045] The basic needles 10 provided on the support plate 1 include long needles and short needles, which are staggered on the support plate 1. For example... Figure 5-7 As shown, in this embodiment, the basic acupuncture 10 is divided into long needle rows composed of long needles and short needle rows composed of short needles, with the long needle rows and short needle rows being distributed alternately. Figure 5 A long needle row consists of five basic needles (10 in total), and a short needle row consists of six basic needles (10 in total). Functional needles are placed between different basic needles (10 in total). The scent released by the bird repellent ointment in the functional needles can further repel birds and prevent them from landing.

[0046] like Figure 8As shown, the support plate 1 has a plurality of needle mounting holes 11 for mounting the foundation needles 10. The needle mounting holes 11 are arranged on the surface of the support plate 1 and are distributed in multiple rows corresponding to the long needles and the short needles.

[0047] like Figure 9 As shown, the basic needle acupuncture point 10 includes a limiting part 1001, a mounting part 1002, and a tapered part 1003 connected sequentially from bottom to top. Both the limiting part 1001 and the mounting part 1002 are cylindrical, and they are coaxially distributed. The large-diameter end of the tapered part 1003 and the diameter of the limiting part 1001 are both larger than the diameter of the mounting part 1002. The diameter of the mounting part 1002 is slightly smaller than the diameter of the needle acupuncture mounting hole 11, so that the mounting part 1002 can be inserted into the needle acupuncture mounting hole 11.

[0048] The basic needle 10 is an integral structure injection molded from insulating material. The bearing plate 1 has a certain elasticity. By forcefully pushing the basic needle 10, the conical part 1003 expands the diameter of the needle mounting hole 11, so that the mounting part 1002 can be inserted into the needle mounting hole 11.

[0049] In other embodiments of the present invention, the mounting portion 1002 is detachably connected to the limiting portion 1001 or the tapered portion 1003. For example, in a threaded connection, an axially extending threaded post is provided on the side of the mounting portion 1002 facing the limiting portion 1001 or the tapered portion 1003, and a threaded groove adapted to the threaded post is formed in the corresponding limiting portion 1001 or the tapered portion 1003. When the mounting portion 1002 is inserted into the needle-punched mounting hole 11, the mounting portion 1002 is rotated to separate it from the limiting portion 1001 or the tapered portion 1003. After the mounting portion 1002 is inserted into the needle-punched mounting hole 11, the mounting portion 1002 and the corresponding limiting portion 1001 or the tapered portion 1003 are then rotated and fixed.

[0050] The support plate 1 is provided with multiple fasteners 13 to fix the support plate 1 after it is wrapped around the power transmission line, or to splice the support plates 1 to extend the length of the support plate 1. The support plate 1 is provided with fastening holes 12 corresponding to the fasteners 13 one by one. The fasteners 13 and fastening holes 12 are all located on the edge of the support plate 1 and are symmetrically distributed.

[0051] like Figure 5 , 8 As shown, the edge of the support plate 1 is provided with connecting ears, and the fasteners 13 and fastening holes 12 are both formed on the connecting ears. There are multiple connecting ears arranged at intervals along the long side of the support plate 1, and one connecting ear is arranged along the short side of the support plate 1. The connecting ears are fixedly connected to the support plate 1, specifically by integral molding or adhesive bonding. In this embodiment, the connecting ears and the support plate 1 are integrally molded from insulating material.

[0052] like Figure 10 As shown, the structure of the fastener 13 is similar to that of the basic needle punch 10. Both include a limiting part 1001, a mounting part 1002, and a conical part 1003 connected sequentially from bottom to top. The difference is that the conical part 1003 of the fastener 13 has a smaller conical height. The limiting part 1001 of the fastener 13 is fixed to the connecting lug of the support plate 1. The mounting part 1002 of the fastener 13 can be inserted into the fastening hole 12 on the opposite side to fix or splice the support plate 1. The specific process of inserting into the fastening hole 12 is the same as the process of inserting the mounting part 1002 into the needle punch mounting hole 11, and will not be described again here.

[0053] As another way of setting the fastener 13, the height of the mounting part 1002 of the fastener 13 is the sum of the thicknesses of the two bearing plates 1. The bearing plate 1 is provided with a fastener mounting hole 14. The fastener 13 is first set in the fastener mounting hole 14. After the bearing plate 1 wraps the power transmission line, the tapered part 1003 of the fastener 13 passes through the fastening hole 12 on the opposite side to achieve fixation with the bearing plate 1 on the opposite side.

[0054] When the bearing plate 1 is fixed to the transmission line, the length direction of the bearing plate 1 is kept consistent with the extension direction of the transmission line. After the bearing plate 1 wraps the transmission line, the fasteners 13 on the bearing plate 1 are inserted into the fastening holes 12 on the opposite side, so that the bearing plate 1 is formed into a cylindrical shape that wraps around the outside of the transmission line. The basic needles 10 and the functional needles are located on the outer surface of the bearing plate 1 to prevent birds from landing on the transmission line.

[0055] like Figure 11 As shown, when the length of the support plate 1 is insufficient, the fastener 13 on the connecting lug on the short side of the support plate 1 is inserted into the fastening hole 12 on the connecting lug on the short side of the other support plate 1, thus splicing the two support plates 1. The length after splicing can be freely adjusted according to the number of splices, and the fastener connection allows for quick installation.

[0056] It should be noted that the flexible bearing plate 1 will deform when wrapped around the transmission line, but since the mounting cylinder 2 fixed on it is a rigid structure, the deformation of the bearing plate 1 will not affect the fixing effect of the base 301 in the mounting cylinder 2.

[0057] The entire functional needle of this invention has a split structure. The needle rod 3, connecting cylinder 4, receiving cylinder 7 and needle 6 are all connected by threads, which makes disassembly and assembly more convenient and facilitates production and subsequent maintenance.

[0058] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
