Description

Technical Field

[0001] This invention relates to a foldable bird-proof isolation net for a substation equipment gantry. Background Technology

[0002] As a core hub of the power system, the safe and stable operation of substations directly affects the reliability of the power grid. The equipment gantry frames within substations, serving as supporting and protective structures for various electrical equipment, have gaps that easily become nesting and roosting sites for birds. Bird droppings and nesting debris can easily fall onto the surfaces of the electrical equipment below, causing equipment insulation degradation, short circuits, and tripping, and in severe cases, even large-scale power outages, resulting in significant losses to power system safety and social production and daily life. Therefore, installing bird-proof isolation devices at the equipment gantry frames of substations to prevent birds from entering the gaps is a necessary measure to ensure the safe operation of substation equipment.

[0003] Currently, the bird-proof netting used on substation equipment gantry frames is mostly a fixed, integrated structure with fixed dimensions and shape, making it impossible to flexibly adjust according to the actual gap size of the equipment gantry and the installation space. Because the specifications of equipment gantry frames vary in different areas of a substation, and the gap shapes are often irregular, the fixed, integrated netting often fails to fit tightly against the gantry gaps during installation, leading to problems such as loose installation and insufficient fit. This results in loopholes in bird protection and prevents it from fully fulfilling its bird-proofing function.

[0004] Meanwhile, integrated bird-proof netting is bulky, taking up a lot of space during transportation and storage, making it inconvenient to handle and increasing the labor intensity of construction workers. During installation and dismantling, the netting needs to be moved and handled as a whole, resulting in poor adaptability and an inability to quickly adapt to different equipment gantry specifications, leading to low installation efficiency. Furthermore, some existing foldable bird-proof netting designs have unreasonable folding structures, failing to securely fix the netting after folding, making it difficult to form a structure that tightly fills the gaps in the equipment gantry. They also lack reliable fixing and locking mechanisms, making them prone to loosening and unfolding after folding, affecting the protective effect. Moreover, their fixing mechanisms are mostly rigid connections, unable to be flexibly adjusted according to the shape of the gantry, resulting in poor stability after installation. During long-term use, they are easily affected by external environmental factors (such as wind, equipment vibration, etc.) and may fall off, further reducing the reliability of bird-proof netting. Summary of the Invention

[0005] The present invention addresses the problems existing in the prior art, namely, the technical problem to be solved by the present invention is to provide a foldable bird-proof isolation net for substation equipment gantry.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a foldable bird-proof isolation net for a substation equipment gantry, comprising an isolation net one, an isolation net two, a folding assembly, a fixing mechanism, and a locking mechanism. The isolation net two is symmetrically arranged on both sides of the isolation net one. The folding assembly is arranged between the isolation net one and the isolation net two, and is used to drive the isolation net one and the isolation net two to rotate relative to each other. The fixing mechanism is used to fix the isolation net two on both sides after rotating the isolation net one and the isolation net two on both sides into a triangle. The locking mechanism is used to lock two adjacent isolation nets one.

[0007] Furthermore, the folding assembly includes several connector 1s fixed side-by-side at intervals to the first isolation net, several connector 2s fixed side-by-side at intervals to the second isolation net, and a fixed shaft disposed between the first isolation net and the second isolation net. Both connector 1s and connector 2s are sleeved on the outer periphery of the fixed shaft and rotatably connected to the fixed shaft.

[0008] Furthermore, limiting plugs are fixedly sleeved at both ends of the fixed shaft.

[0009] Furthermore, there are several fixing mechanisms arranged side by side at intervals. Each fixing mechanism includes an arc-shaped block 1 and an arc-shaped block 2 with their arc openings facing each other. The arc-shaped block 1 and the arc-shaped block 2 are respectively fitted onto the ends of the isolation nets 2 on both sides away from the isolation net 1. An adjustment component is provided between the arc-shaped block 2 and the arc-shaped block 1.

[0010] Furthermore, the adjustment assembly includes a first fixed block fixedly disposed on the top of the first arc-shaped block and a second fixed block fixedly disposed on the top of the second arc-shaped block. The positions of the first fixed block and the second fixed block are corresponding. A threaded rod is rotatably connected to the middle of the first fixed block, and sliding guide rods are arranged parallel to each other on the two sides of the threaded rod and fixedly disposed on the first fixed block. A threaded hole that mates with the threaded rod is provided in the middle of the second fixed block, and sliding holes that slidably mate with the sliding guide rods are provided on both sides of the threaded hole.

[0011] Furthermore, a plurality of parallel and spaced insertion rods are provided on the upper part of one end face of the arc-shaped block one facing the arc-shaped block two, and an elastic element is sleeved on the outer side of the insertion rod, with the two ends of the elastic element abutting against the arc-shaped block one and the arc-shaped block two respectively; a plurality of parallel and spaced insertion holes are provided on the upper part of one end face of the arc-shaped block two facing the arc-shaped block one, and the insertion rods are inserted into the insertion holes.

[0012] Furthermore, several arc-shaped pads are arranged side by side at intervals between the ends of the two isolation nets away from the first isolation net, and the positions of the arc-shaped pads correspond to the positions of the several fixing mechanisms.

[0013] Furthermore, the locking mechanism includes a square rod disposed on one side of the fixed shaft and a locking rod disposed on the other side of the fixed shaft. The locking rod has a square hole for engaging with the square rod. A locking hole one is provided through the side of the square rod, and a locking hole two is provided through the side of the locking rod. When the square rod is inserted into the square hole, the positions of the locking hole one and the locking hole two are aligned. Locking pins are inserted into the locking hole one and the locking hole two.

[0014] Furthermore, a sleeve is vertically fixed to the outer periphery of the locking rod and fitted onto the outside of the locking post. The locking post and the sleeve are slidably fitted. Two elongated straight grooves are symmetrically formed on the periphery of the sleeve. The elongated straight grooves extend along the axial direction of the sleeve and penetrate the periphery of the sleeve. A fixing rod is fixedly installed parallel to the elongated straight grooves. A movable piece and a fixing block are slidably fitted on the fixing rod. The fixing block is fixed to the side of the movable piece facing away from the locking rod and is fixedly connected to the locking post. A compression spring is provided between the end of the movable piece facing away from the locking rod and the end of the elongated straight groove away from the locking rod. The compression spring is fitted onto the outside of the fixing rod.

[0015] Furthermore, the sleeve has symmetrical extension grooves on both sides of the long straight groove at one end near the locking rod. The extension grooves are connected to the long straight grooves. A locking groove is provided on the side of the extension groove near the locking rod. Locking plates are symmetrically arranged on both sides of the fixed block at one end away from the movable plate. The fixed block has an arc-shaped long groove to facilitate the movement of the fixing rod. The center of the arc-shaped long groove coincides with the center of the locking pin. After the locking pin rotates, it drives the fixed block into the extension groove on one side. The locking groove and the locking plate are mutually compatible.

[0016] Compared with the prior art, the present invention has the following effects: The present invention is reasonably designed and achieves the flipping and folding of isolation net one and isolation net two through the folding component, thereby reducing the overall volume of the isolation net. This greatly facilitates the transportation, storage and on-site installation of the isolation net, reduces the labor intensity during handling and construction, improves construction efficiency, and solves the problems of large size, inconvenient transportation and storage and complicated installation of traditional bird nets.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0021] like Figures 1-10As shown, this invention provides a foldable bird-proof isolation net for substation equipment gantry, aiming to solve the problems of poor adaptability, inconvenient transportation and installation, unreliable fixing, and poor bird-proofing effect of existing isolation nets. It includes one isolation net 1, two isolation nets 201, a folding assembly 20, a fixing mechanism 30, and a locking mechanism. The two isolation nets 201 are symmetrically arranged on both sides of the isolation net 1. The folding assembly is located between the isolation net 1 and the isolation nets 201, and is used to drive the relative angle flipping of the isolation nets 1 and 201. That is, the two isolation nets 2 and one isolation net 1 are connected by the folding assembly to form a three-section net structure, achieving adjustable spatial form. The fixing mechanism is used to fix the isolation nets 201 on both sides after flipping the isolation net 1 and the two isolation nets 201 on both sides into a triangle. When multiple foldable bird-proof isolation nets are used in combination, the locking mechanism is used to lock the isolation nets 1 of two adjacent foldable bird-proof isolation nets.

[0022] It should be noted that, in terms of material selection, both isolation net 1 and isolation net 2 can adopt 304 stainless steel wire mesh with anti-corrosion treatment or carbon fiber reinforced composite material mesh structure with high weather resistance, and the physical size of the mesh can be set to no more than 15mm×15mm.

[0023] In this embodiment, the folding assembly includes several connectors 1 2 fixed side-by-side at intervals at one end edge of the isolation net 1 near the isolation net 2 101, several connectors 2 0 2 fixed side-by-side at intervals at one end edge of the isolation net 2 101 near the isolation net 1, and a fixed shaft 201 disposed between the isolation net 1 and the isolation net 2 101. One end of each connector 1 2 is fixedly connected to the isolation net 1, and the other end is sleeved on the outer periphery of the fixed shaft 201 and rotatably connected to the fixed shaft 201, forming a rotating pair. One end of each connector 2 0 2 is fixedly connected to the isolation net 2, and the other end is sleeved on the outer periphery of the fixed shaft 201 and rotatably connected to the fixed shaft 201, forming a rotating pair.

[0024] In this embodiment, both ends of the fixed shaft 201 are fixedly fitted with limiting plugs 203 to prevent the first connector and the second connector from slipping off the fixed shaft.

[0025] In this embodiment, there are several fixing mechanisms arranged side-by-side at intervals. Each fixing mechanism includes an arc-shaped block 3 and an arc-shaped block 301 with their arc openings facing each other. The arc-shaped blocks 3 and 301 are respectively fitted onto the ends of the isolation nets 101 on both sides away from the isolation net 1, that is, arc-shaped block 3 is fitted onto one isolation net and arc-shaped block 301 is fitted onto the other isolation net. Further, an adjustment component is provided between arc-shaped block 301 and arc-shaped block 301. The adjustment component connects arc-shaped block 3 and arc-shaped block 301 and adjusts the distance between them. The fixing mechanism is used to fix the isolation nets 1 and 101 into a triangle shape after flipping to fill the substation equipment gantry.

[0026] In this embodiment, the adjustment assembly includes a first fixing block 4 fixedly disposed on the top of the first arc-shaped block 3 and a second fixing block 401 fixedly disposed on the top of the second arc-shaped block 301. The positions of the first fixing block 4 and the second fixing block 401 are corresponding. A threaded rod 402 is rotatably connected to the middle of the first fixing block 4. The threaded rod 402 passes through the first fixing block 4. A limit ring 406 is fixedly disposed on the outer surface of the threaded rod 402. The limit ring 406 is located on both sides of the first fixing block 4 to prevent the threaded rod 402 from detaching from the first fixing block 4. A knob 403 is provided at the end of the threaded rod 402 away from the second fixing block 401 to facilitate manual rotation of the threaded rod 402. The threaded rod 402 has sliding guide rods 405 fixedly mounted on the first fixed block 4 on both sides. The second fixed block 401 has a threaded hole 407 in the middle that mates with the threaded rod 402. The threaded rod 402 is screwed into the threaded hole 407. The two sides of the threaded hole 407 have sliding holes 404 that slidably engage with the sliding guide rods 405. In use, the threaded rod is rotated by the knob 403. The threaded rod drives the second fixed block and the second arc-shaped block to move along the sliding guide rod 405 toward the side where the first fixed block is located, or toward the side away from the first fixed block.

[0027] In this embodiment, a plurality of parallel, spaced-apart insertion rods 303 are provided on the upper part of one end face of the arc-shaped block 3 facing the arc-shaped block 2 301. An elastic element 304 is sleeved on the outer side of each insertion rod 303, and both ends of the elastic element 304 abut against the arc-shaped block 3 and the arc-shaped block 2 301, respectively. A plurality of parallel, spaced-apart insertion holes 302 are provided on the upper part of one end face of the arc-shaped block 2 301 facing the arc-shaped block 3, with the insertion holes corresponding to the positions of the insertion rods. The insertion rods 303 are inserted into the insertion holes 302. An elastic element 304 (in a pre-compressed state) is sleeved on the insertion rod 303, located between the arc-shaped block 3 and the arc-shaped block 2 301, providing elastic clamping force and enhancing the stability of the fixing mechanism and the equipment gantry. It should be noted that the elastic element can be a spring sleeved on the outer side of the insertion rod. The elastic force of the elastic element provides an initial tension load to the two arc-shaped blocks, pointing in opposite directions or a specific direction.

[0028] In this embodiment, when the triangle is formed, several arc-shaped pads 305 are arranged side-by-side at intervals between the ends of the two isolation nets 101 that are away from the first isolation net 1. The positions of the arc-shaped pads 305 correspond to the positions of the fixing mechanisms, and the two ends of the arc-shaped pads contact the edges of the two isolation nets. By setting the triangle shape, the arc-shaped pads 305 between the ends of the two isolation nets 101 that are away from the first isolation net 1 serve to buffer vibration.

[0029] In this embodiment, the locking mechanism is used to quickly lock adjacent isolation nets 1 to prevent gaps from accidentally occurring during the operation of the isolation nets and to ensure the structural stability of the isolation nets. The locking mechanism includes a square rod 5 disposed on one side of the fixed shaft 201 and a locking rod 502 disposed on the other side of the fixed shaft. Specifically, the square rod 5 is fixedly disposed on the end face of the limiting plug 203 at one end of the fixed shaft 201 away from the fixed shaft; the locking rod 502 is fixedly disposed on the end face of the limiting plug 203 at the other end of the fixed shaft 201 away from the fixed shaft. Furthermore, the locking rod 502 has a square hole 504 for insertion and engagement with the square rod 5. The side of the square rod 5 has a first locking hole 501, and the side of the locking rod 502 has a second locking hole 503 radially. Both the first locking hole 501 and the second locking hole 503 are round holes. When the square rod 5 is inserted into the square hole 504, the positions of the first locking hole 501 and the second locking hole 503 are aligned. Locking pins 505 are inserted into the first locking hole 501 and the second locking hole 503. The locking pins are used to lock the square hole and the locking rod, preventing the square rod from rotating and disengaging from the square hole, thereby fixing the position of the adjacent isolation net.

[0030] In this embodiment, a sleeve 6 is vertically fixed to the outer periphery of the locking rod 502 and sleeved on the outside of the locking post 505. The locking post 505 and the sleeve 6 are slidably engaged. A pull rod 506 is fixed to the end face of the locking post away from the locking rod. The locking post can be pushed or pulled by the pull rod. The pull rod is designed to facilitate the operator to insert or remove the locking post 505. Furthermore, two elongated straight grooves 601 are symmetrically formed on the peripheral sidewall of the sleeve 6. The elongated straight grooves 601 extend along the axial direction of the sleeve 6 and penetrate the peripheral sidewall of the sleeve 6. A fixing rod 602 is fixedly installed parallel to the elongated straight groove 601. A movable piece 603 and a fixed block 604 are slidably sleeved on the fixing rod 602. The fixed block 604 is fixed to the side of the movable piece 603 facing away from the locking rod 502. The fixed block 604 is fixedly connected to the locking post 505. When the locking post moves, it drives the fixed block to move synchronously. A compression spring 606 (in a compressed state) is provided between the end of the movable piece 603 facing away from the locking rod 502 and the end of the elongated straight groove 601 away from the locking rod 502. The compression spring 606 is sleeved on the outside of the fixing rod 602. When in use, when the locking pin is pushed by the pull rod, the locking pin drives the fixed block and the movable piece to move synchronously, and the fixed block and the movable piece move along the fixed rod; when the locking pin passes through the first locking hole and the second locking hole, the elastic force generated by the compression spring in the compressed state always acts on the movable piece, which can keep the locking pin in the state of passing through the first locking hole and the second locking hole.

[0031] In this embodiment, the sleeve 6 has symmetrically arranged extension grooves 607 on both sides of the elongated straight groove 601 at one end near the locking rod 502. The extension grooves extend circumferentially along the sleeve and are interconnected with the elongated straight groove 601. A locking groove 608 is provided on the side of the extension groove 607 near the locking rod 502. The fixed block 604 has symmetrically arranged locking pieces 605 on both sides of one end facing away from the movable piece 603. The locking pieces are adapted to the geometric contours of the locking grooves. The fixed block 604 has a groove to facilitate the movement of the fixed rod 602. The arc-shaped long groove 609 is centered on the locking pin 505. When the fixing block moves to the position of the extension groove, the locking pin is rotated to one side. After the locking pin 505 rotates, it drives the fixing block 604 into the extension groove 607 on one side. Then, the locking pin is released, and the fixing block can continue to move towards the side where the locking rod 502 is located under the elastic force of the compression spring 606, so that the locking piece 605 extends into the locking groove 608, realizing the mutual adaptation between the locking groove 608 and the locking piece 605. Through the setting of the extension groove, the locking groove, and the locking piece, the locking pin is effectively prevented from easily disengaging from the locking hole one and the locking hole two under the action of external force.

[0032] The working principle of the invention is as follows: This embodiment provides a foldable bird-proof isolation net for a substation equipment gantry. Its main structure includes an isolation net 1, with two isolation nets 101 symmetrically arranged on both sides of the isolation net 1. Folding components are installed between the isolation net 1 and the two isolation nets 101 on both sides to allow for flipping and folding of the isolation nets 1 and 101. To secure the folded isolation net, a fixing mechanism is fitted onto the side of the isolation net 101 away from the isolation net 1. The fixing mechanism consists of an arc-shaped block 3, an arc-shaped block 301, an adjustment component, and an arc-shaped pad 305. The arc-shaped pads 305 are symmetrically fixed on the side of the isolation net 101 away from the isolation net 1. The adjustment component is installed between the arc-shaped block 3 and the arc-shaped block 301 to adjust the distance between them to accommodate equipment gantry of different specifications. To prevent adjacent isolation nets from accidentally unfolding after folding, locking mechanisms are provided at both ends of the folding assembly. The locking mechanisms include components such as a square rod 5, a locking rod 502, a locking post 505, and a sleeve 6. The square rod 5 is fixed to one side of the limiting plug 203 at one end of the fixed shaft 201, and the locking rod 502 is fixed to one side of the limiting plug 203 at the other end of the fixed shaft 201, so as to achieve quick locking of adjacent isolation nets.

[0033] Folding Operation: When the isolation net needs to be folded for transportation or storage, first release the locking mechanism. Pull the lever 506 to pull the locking pin 505 out of the locking hole 1 501 and the locking hole 2 503. At this time, the lock between adjacent isolation nets is released. Then, the folding assembly realizes the flipping and folding of isolation net 1 and isolation net 2 101. Connector 1 2 and connector 2 202 rotate around the fixed shaft 201. The limit plug 203 can prevent connector 1 2 and connector 2 202 from falling off from both ends of the fixed shaft 201 until isolation net 1 and isolation net 2 101 on both sides are folded and attached, completing the folding operation and reducing the overall volume of the isolation net.

[0034] The working principle of the foldable bird-proof isolation net on the substation equipment gantry mainly consists of four parts: folding operation, fixing operation, locking operation, and unlocking folding, as detailed below: Locking Operation: After the isolation net is unfolded and adjusted to a suitable angle, push the pull rod 506 to drive the locking pin 505 into the corresponding locking hole 1 501 and locking hole 2 503, thereby locking the square rod 5 and the locking rod 502, fixing the position of the adjacent isolation net and preventing accidental rotation of the isolation net. Then rotate the locking pin, and after the locking pin 505 rotates, it drives the fixing block 604 into the extension groove 607 on one side. Then release the locking pin, and the fixing block continues to move towards the side where the locking rod 502 is located under the elastic force of the compression spring 606, so that the locking piece 605 extends into the locking groove 608, realizing the mutual adaptation between the locking groove 608 and the locking piece 605, limiting the locking pin 505, preventing the locking pin 505 from accidentally falling off, and ensuring the reliability of locking.

[0035] Fixing Operation: When it is necessary to install the isolation net on the substation equipment gantry, first unfold the folded isolation net and flip the isolation net 101 so that the isolation net 1 and the two sides of the isolation net 101 form a triangular structure to fit the gap of the equipment gantry. Then adjust the fixing mechanism, turn the knob 403 to drive the threaded rod 402 to rotate, the threaded rod 402 engages with the threaded hole 407 on the fixing block 401, pushing the arc block 3 and the arc block 301 closer to each other, the plug rod 303 slides in the plug hole 302, the elastic element 304 deforms and provides elastic clamping force, the arc pad 305 can increase the contact area between the fixing mechanism and the isolation net 101, reduce hard contact damage, and finally the arc block 3 and the arc block 301 fit tightly against the equipment gantry, fixing the isolation net into a triangle and filling the gap of the gantry.

[0036] Unlocking and Folding: When it is necessary to disassemble or fold the isolation net, pull the lever 506 to move the fixing block 604, and the locking piece 605 will disengage from the locking groove 608. Then, rotate the locking pin to make the fixing block enter the long straight groove. Continue to pull the lever 506 to make the locking pin 505 pull out the locking hole 1 501 and the locking hole 2 503, thereby unlocking. During the unlocking process, the compression spring 606 is compressed. After unlocking, the isolation net 1 and the isolation net 2 101 can be flipped and folded by the folding assembly for easy disassembly and transportation.

[0037] The advantages of this invention are: (1) By using the folding component to achieve the flipping and folding of isolation net one and isolation net two, the overall volume of the isolation net is reduced, which greatly facilitates the transportation, storage and on-site installation of the isolation net, reduces the labor intensity in the handling and construction process, improves the construction efficiency, and solves the problems of large volume, inconvenient transportation and storage and complicated installation of traditional bird nets. (2) The isolation net one and the two side isolation net two can be flipped through the folding components to form a triangular structure. With the clamping and fixing of the fixing mechanism, the isolation net is tightly filled in the gap of the substation equipment gantry, effectively blocking birds from entering the gantry and avoiding the safety hazards caused by bird activities to the substation equipment, thus ensuring the stable and safe operation of the substation equipment. (3) The distance between arc block one and arc block two can be adjusted by rotating the knob in the adjustment component, and arc pads are provided to achieve the effect of adapting to the installation requirements of substation equipment gantry of different specifications. At the same time, it reduces the hard contact damage between the fixing mechanism and the isolation net two, protects the structural integrity of the isolation net, and extends the service life of the isolation net. (4) The locking mechanism adopts the plug-in cooperation of the locking pin and the locking hole, combined with the limiting effect of the compression spring, the locking plate and the locking groove, to achieve the effect of quickly locking the position of the adjacent isolation net, preventing the isolation net from rotating accidentally during operation, and avoiding the locking pin from falling off accidentally, thus ensuring the reliability of locking and the structural stability of the isolation net after installation. (5) The folding assembly adopts the rotational cooperation of connector one, connector two and fixed shaft, and the fixed shaft is equipped with limit plugs at both ends, which achieves the effect of flexible and smooth flipping and folding of isolation net one and isolation net two, while preventing the connectors from slipping off from both ends of the fixed shaft, ensuring the safety and smoothness of the folding operation, and further improving the ease of use of the isolation net; (6) The setting of elastic elements in the fixing mechanism achieves the effect of providing elastic clamping force for arc block one and arc block two, making the fixing mechanism fit more closely with the substation equipment gantry, improving the fixing stability of the isolation net after installation, avoiding the isolation net from loosening due to equipment operation vibration, and further ensuring the bird protection isolation effect.
