Description

Technical Field

[0001] This invention relates to the field of insulating board technology, and more specifically to an electrical isolation insulating baffle. Background Technology

[0002] Insulating barriers are made of insulating materials and are commonly used safety protection devices in power maintenance operations. They can effectively isolate live parts, limit the range of movement of workers, and prevent personnel from accidentally entering and approaching high-voltage live areas. They are widely used in maintenance work sites for equipment such as disconnect switches.

[0003] like Figure 1 The image shows a first-generation product of the prior art, which consists of an insulating plate and a fastening assembly that fastens to the porcelain insulator. The fastening assembly is fixed to the insulating plate and consists of several equally spaced fastening slots and fastening claws. The fastening slots are constructed on the insulating baffle. In actual use, this product has some problems. Due to the equally spaced fastening slots, it cannot fasten to the porcelain insulator in all cases during actual operation (there is an error in the spacing between the porcelain insulators), which makes it unusable in some situations.

[0004] Therefore, this application provides an electrical isolation insulating baffle. Summary of the Invention

[0005] The purpose of this invention is to design an adjustable electrical isolation insulating baffle with a snap-fit ​​assembly.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution: An electrical isolation insulating baffle includes an insulating plate body, a plurality of fastening grooves and fastening components. The fastening grooves are disposed on the fastening components and the fastening components are disposed on the edge of the insulating plate body. The fastening components can be adjusted and moved along the length direction of the edge of the insulating plate body.

[0007] Furthermore, the fastening assembly includes a movable plate and fastening claws disposed on the movable plate, and the fastening groove is U-shaped and formed on the movable plate.

[0008] Furthermore, the snap-fit ​​claw includes a crescent-shaped curved plate, one end of which is pivotally mounted on a movable plate. The curved plate is used to close the U-shaped opening of the porcelain bottle after the snap-fit ​​groove surrounds it. The outer arc edge of the curved plate is constructed with ratchet-like teeth. A locking element is also installed on the movable plate to lock the curved plate.

[0009] Furthermore, the locking element includes a device block fixedly mounted on a movable plate, a chamfered rod slidably passing through the device block, a pawl block fixed at the end of the chamfered rod, the pawl block engaging with a ratchet tooth, a spring sleeved on the chamfered rod, one end of the spring abutting against the back of the pawl block and the other end abutting against the device block and used to force the pawl block closer to the ratchet tooth, and a pull ring fixed at the other end of the chamfered rod.

[0010] Furthermore, the insulating plate has a waist-shaped groove along its length, and a first U-shaped plate is fixed at the edge of the movable plate to clamp the edge of the insulating plate. A first bolt passing through the waist-shaped groove is provided through the first U-shaped plate, and a first nut is threaded onto the first bolt. The first bolt is slidably fitted in the waist-shaped groove.

[0011] Furthermore, an edge adjustment plate and a middle adjustment plate are provided between adjacent movable plates. Both the edge adjustment plate and the middle adjustment plate include a second U-shaped plate that clamps the edge of the insulating plate. A second bolt passing through a waist-shaped groove is provided through the second U-shaped plate. A second nut is threaded onto the second bolt. The second bolt is slidably fitted in the waist-shaped groove. An insulating movable plate is fixed to the side of the second U-shaped plate. The insulating movable plate and the movable plate are fitted together vertically. An adjustment gap is provided between the second U-shaped plate and the first U-shaped plate of the edge adjustment plate. An auxiliary plate that closes the adjustment gap is integrally constructed on the insulating movable plate of the edge adjustment plate.

[0012] Furthermore, the insulating plate includes a first plate and a second plate, which are rotatably connected by a hinge. The waist-shaped groove is formed on the second plate, and the second plate is provided with intersecting reinforcing ribs. A support member is provided between the first plate and the second plate, which is used to keep the first plate in a parallel or perpendicular state.

[0013] Furthermore, the support member includes a first slide cylinder fixed to the first plate and a second slide cylinder fixed to the second plate. A first support rod is slidably inserted into the first slide cylinder, and a second support rod is slidably inserted into the second slide cylinder. The first support rod and the second support rod can be aligned or perpendicularly connected.

[0014] Furthermore, the portion of the first support rod near the second support rod is recessed, the second support rod is hollow inside and used to engage the recessed portion of the first support rod, and both the first and second support rods have anti-disengagement protrusions on their shafts.

[0015] Furthermore, a vertical slot is constructed at the shaft of the second support rod for insertion of the end of the first support rod, and a pair of elastic arc-shaped plates for clamping the shaft of the first support rod are fixed on the hollow inner wall of the second support rod.

[0016] The beneficial effects of this invention are as follows: 1. The present invention has an elongated waist-shaped groove on the edge of the insulating board. The fastening assembly clamps the board through the first U-shaped plate and passes through the waist-shaped groove with the first bolt, and can slide left and right arbitrarily along the edge of the board. The position of the fastening claw can be finely adjusted in real time according to the actual spacing of the porcelain insulators on site, so as to be compatible with manufacturing tolerances, installation deviations, and non-standard spacing of old equipment, thereby solving the problems of misalignment and inability to install, and improving versatility.

[0017] 2. The present invention is provided with a side adjustment plate and a middle adjustment plate. The plate body is clamped by the second U-shaped plate and slides synchronously along the waist-shaped groove. The insulating moving plate and the moving plate are attached to each other and can move synchronously with the fastening assembly, thereby filling the gap on the plate surface after the sliding adjustment. This ensures that the entire insulating baffle always remains as a continuous and closed whole.

[0018] 3. The present invention divides the insulating plate into a first plate and a second plate, which are connected by a hinge in the middle. With the help of the support, it can realize two forms: parallel straight line layout and vertical right angle layout. It can be used for straight channel isolation, as well as for substation corner and equipment corner isolation. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] This invention provides an electrical isolation insulating baffle, which improves upon the traditional fixed equidistant snap-fit ​​groove structure by setting a waist-shaped groove along the edge of the insulating plate. The snap-fit ​​assembly slides freely along the waist-shaped groove through a U-shaped clamping plate and bolts, and its position can be adjusted according to the actual spacing of the porcelain insulators on site. It is not limited by the installation error of the porcelain insulators, thus solving the problems of fixed spacing not being able to be aligned and on-site installation being impossible. Example

[0023] Please see Figures 1 to 4 ,like Figure 1The diagram shows the existing product structure, where the snap-fit ​​groove 2 and the insulating plate 1 are integrally fixed, and the snap-fit ​​spacing is not adjustable. In actual use, it is affected not only by the installation error of the porcelain insulator but also by the different spacing of the porcelain insulators, resulting in a narrow range of applications. Based on the above defects, this application improves upon the following: the whole includes an insulating plate 1, several snap-fit ​​grooves 2, and snap-fit ​​components 3; the snap-fit ​​grooves 2 are independently set on the snap-fit ​​components 3, rather than being directly opened on the insulating plate 1; the snap-fit ​​components 3 are integrally assembled on the edge of the insulating plate 1 and can slide and move along the length of the insulating plate 1.

[0024] In actual use, the installation position of the fastening component 3 can be changed by sliding the drive directly according to the actual spacing of the porcelain insulators on site. Because the fastening groove 2 moves synchronously with the fastening component 3 as a whole, it can fully adapt to different porcelain insulator spacing and installation deviations. There will be no situation where the hole positions do not match or cannot be fastened, which greatly expands the applicable scenarios and on-site adaptability.

[0025] Please see Figure 9 Here is a detailed explanation of the fastening principle between the fastening component 3 and the porcelain bottle: The fastening component 3 includes a movable plate 31 and a fastening claw 32 mounted on the movable plate 31; the movable plate 31 has a U-shaped fastening groove 2, which can surround and limit the porcelain bottle from three directions, and then the fastening claw 32 rotates to close the U-shaped opening, so as to achieve full-enclosure locking and limiting.

[0026] Specifically, both the snap-fit ​​claw 32 and the movable plate 31 are integrally molded from high-strength insulating plastic to ensure insulation and strength. The snap-fit ​​claw 32 mainly consists of a crescent-shaped curved plate 321 and ratchet teeth 322 at the outer arc of the curved plate 321. One end of the curved plate 321 is pivotally hinged to the movable plate 31 and can rotate freely. After the curved plate 321 is closed by rotation, it is used to seal the opening of the U-shaped snap-fit ​​groove 2 to prevent the porcelain insulator from falling out. A corresponding locking element 323 is assembled on the movable plate 31. The locking element 323 includes a device block 3231 fixed on the movable plate 31, and a chamfered rod 3232 slides through the device block 3231. The chamfered rod 3232 adopts a flat structure design to prevent itself from rotating circumferentially during sliding. Meanwhile, a pawl block 3233 is fixed to the end of the chamfering rod 3232, and the pawl block 3233 and the ratchet 322 mesh with each other; a spring 3234 is sleeved on the outside of the chamfering rod 3232, one end of the spring 3234 abuts against the back of the pawl block 3233 and the other end abuts against the end face of the device, and under normal conditions, it continuously provides a clamping force close to the ratchet 322 to the pawl block 3233; a pull ring 3235 is fixed to the outer end of the chamfering rod for manual unlocking operation.

[0027] During operation: The bent plate 321 is hinged to the movable plate 31 and can be opened and closed freely, forming a fully enclosed structure with the U-shaped fastening groove 2; a ratchet-type ratchet 322 is set on the outside of the bent plate 321, and the spring 3234 normally stores force to push the pawl block 3233 to tightly engage with the ratchet 322, forming a one-way check and limit structure, so that the bent plate 321 can only rotate in the closing direction and cannot be released on its own in the reverse direction; when the pull ring 3235 is pulled outward, it drives the chamfered rod 3232 to slide and compress the spring 3234, so that the pawl block 3233 disengages from the ratchet 322, and the bent plate 321 can be rotated in the reverse direction to complete the unlocking, realizing the functions of manual unlocking and automatic locking.

[0028] Please see Figure 4 , Figure 6 as well as Figure 9 The sliding adjustment method of the movable plate 31 is described in detail here: A through-type waist-shaped groove 4 is opened along the length of the edge of the insulating plate 1; a first U-shaped plate 311 is fixed on the movable side, and the first U-shaped plate 311 clamps and covers the upper and lower edges of the insulating plate 1; a first bolt 312 is installed through the first U-shaped plate 311, and the first bolt 312 passes vertically through the waist-shaped groove 4 and is threaded with a first nut 313 at its lower end. The first bolt 312 and the waist-shaped groove 4 are in sliding fit. When the first nut 313 is loosened, the first bolt 312 can slide left and right along the waist-shaped groove 4, driving the entire movable plate 31 and the fastening assembly 3 to move synchronously; after adjusting to the appropriate position, the first nut 313 is tightened, and the insulating plate 1 is clamped by the first U-shaped plate 311 to achieve friction locking and complete the position fixation. Example

[0029] This embodiment adds a gap compensation structure based on embodiment 1: large blank gaps are easily generated between two adjacent sets of moving plates 31, resulting in a blind spot for insulation protection. Therefore, a side adjustment plate 5 and a middle adjustment plate 6 are added between adjacent moving plates 31.

[0030] Both the side adjusting plate 5 and the middle adjusting plate 6 include a second U-shaped plate 7, which is also clamped along the edge of the insulating plate 1. A second bolt 8 is threaded through the second U-shaped plate 7, passing through the waist-shaped groove 4 and threaded with a second nut 9. The second bolt 8 also slides in contact with the waist-shaped groove 4. An insulating movable plate 10 is fixed to the side of the second U-shaped plate 7, and the insulating movable plate 10 is fitted against the upper and lower surfaces of the movable plate 31. An adjustment gap 11 is reserved between the second U-shaped plate 7 and the first U-shaped plate 311 of the side adjusting plate 5 for slight adaptation to positional deviations. At the same time, a supplementary plate 15 is integrally constructed on the insulating movable plate 10 of the side adjusting plate 5 to close the adjustment gap 11. Figure 15 As shown, the supplementary plate 15 here is not a true closure, but rather a close-fitting closure that is vertically upward.

[0031] During adjustment: Loosen the second nut 9, and the second bolt 8 can slide along the waist-shaped groove 4, causing the side adjustment plate 5 and the middle adjustment plate 6 to move synchronously; after the position is adjusted, tighten the second nut 9 to lock and fix it. The insulating moving plate 10 and the moving plate 31 are in close contact.

[0032] Please see Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown: On-site installation has two adjustment methods under different working conditions: For different standard porcelain insulator spacing: Before operation, all side adjustment plates 5 and middle adjustment plates 6 can be removed as a whole. Mark the installation position of the fastening assembly 3 on the insulating plate 1 according to the porcelain insulator spacing; loosen the first nut 313, slide the moving plate 31 to the marked position and then lock it. Then assemble the two side adjustment plates 5 in sequence, and add the middle adjustment plate 6 to fill the blank area in the empty position (see assembly status). Figure 6 ).

[0033] For minor deviations in the installation tolerance of porcelain insulators: the adjustment gap 11 reserved between the side adjustment plate 5 and the first U-shaped plate 311 can be used for micro-adjustment. No disassembly and reassembly are required. This can adapt to small-range installation deviations, and the alignment and fastening can be completed by fine adjustment. Example

[0034] Based on Embodiments 1 and 2, this embodiment optimizes the baffle support posture structure: actual maintenance not only requires horizontal plane enclosure, but also has side corner vertical operation conditions, so the insulating plate 1 is set as a foldable support structure.

[0035] The insulating board 1 includes a first board 101 and a second board 102, which are hinged together by a hinge 103. A waist-shaped groove 4 is formed on the second board 102, and the second board 102 is provided with intersecting reinforcing ribs 104. The reinforcing ribs 104 can greatly improve the bending strength of the board. Since the second board 102 bears the fastening assembly 3 and adjusts the load of the board, it is subjected to greater force and is not easy to deform or crack after being strengthened.

[0036] A support member 12 is provided between the first plate 101 and the second plate 102. The support member 12 can lock the two plates to be arranged in parallel and straight or at right angles, adapting to both planar and corner operation scenarios.

[0037] For detailed structure, please refer to [link / reference]. Figure 11 The support member 12 includes a first slide cylinder 121 fixed on the first plate 101 and a second slide cylinder 122 fixed on the second plate 102; a first support rod 123 is slidably inserted into the first slide cylinder 121 and a second support rod 124 is slidably inserted into the second slide cylinder 122; the two support rods can be pulled out and connected together or vertically inserted and locked.

[0038] The first support rod 123 is recessed near the docking end, and the second support rod 124 is hollow inside, allowing the recessed section of the first support rod 123 to be inserted and engaged. Both support rods have anti-detachment protrusions 13 to prevent them from completely sliding out of the slide cylinder. The second support rod 124 also has a vertical slot 14 for the end of the first support rod 123 to be inserted for right-angle positioning. A pair of elastic arc-shaped plates are fixed to the hollow inner wall of the second support rod 124 to clamp the first support rod 123, preventing it from loosening or slipping off without external force.

[0039] When laid out horizontally and straight, the inner section of the first support rod 123 is inserted into the hollow cavity of the second support rod 124, and the two plates are clamped and positioned by the elastic arc plate to keep them aligned. When the vertical corner is set up, the end of the first support rod 123 is inserted into the vertical slot 14 of the second support rod 124 to form a right angle limit, so that the first plate 101 and the second plate 102 are stably kept at a vertical angle, which is suitable for the side isolation operation of the equipment.

[0040] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0041] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the present invention.
