Description

Technical Field

[0001] The invention belongs to the technical field of insulators, and in particular relates to a modular insulator and an auxiliary spreading tool which are easy to install. Background Art

[0002] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. Their purpose is to stretch, support and fix the installed cables and improve the utilization rate of poles. They are used to increase creepage distances and are usually made of glass or ceramic. Insulators are generally used to insulate and fix conductors in high-voltage overhead transmission and distribution lines. Insulator components are assembled into insulator strings for use on lines of different voltage levels. They play two basic roles in overhead transmission lines, namely supporting conductors and preventing current from returning to the ground. Insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions, otherwise the insulators will not have a significant effect and will damage the use and service life of the entire line. However, the existing power insulators have the following main problems during use: First, most of the existing insulators are factory-produced during installation. After completion, the staff directly use the integrated insulator for installation. However, when installing the insulator, the porcelain insulator may be damaged during transportation, and it is necessary to replace and install the entire insulator, which is costly and wastes resources seriously. Secondly, the insulator needs to be replaced regularly due to various reasons during installation and use. At present, the integrated insulator needs to be replaced as a whole. The line insulator is used in large quantities. If all of them are replaced as a whole, the cost will be greatly increased and the workload will be large. Thirdly, for the post-maintenance and replacement of insulators and the maintenance and replacement of damaged insulators, the staff's operation during the replacement of insulators is cumbersome and the installation is troublesome. Therefore, it is very necessary to provide a modular insulator and auxiliary propping tool that is easy to install and has a reasonable structure, modular structure, reduces cost and workload, and is convenient and quick to disassemble and replace.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with embodiments and / or drawings. Example

[0030] like Figure 1-8As shown, a modular insulator that is easy to install includes an insulator string 1, and the insulator string 1 is installed as a whole through an installation component 2; a wire fixing component 3 is detachably installed on the top of the insulator string 1 to achieve the function of tensile support and fixation of the cable; the insulator string 1 is composed of a plurality of modular insulator elements 100, and the modular insulator elements 100 are connected and fixed in a detachable installation manner, and the number of the modular insulator elements 100 can be increased or decreased according to actual needs.

[0031] The modular insulator element 100 includes an shed 11, a connecting fitting 12 is arranged above the shed 11, a mounting fitting 13 is arranged above the connecting fitting 12, a connecting rod 14 is installed at the end of the shed 11 below the connecting fitting 12, and a connector 15 is arranged at the end of the connecting rod 14; a plurality of radial annular grooves 16 are arranged inside the shed 11, which increase the creepage distance and effectively improve the electrical performance, thereby improving its pollution resistance and flashover voltage; the design of the annular groove makes the electric field distribution on the surface of the insulator more uniform, reduces the possibility of local discharge, and thus improves the overall performance and reliability of the insulator.

[0032] The mounting hardware 13 includes a mounting seat 301, a waist-shaped opening groove 302 is arranged at the lower part of the mounting seat 301, a vertical opening groove 303 is arranged at the upper part of the waist-shaped opening groove 302, a first card groove 304 matching the connecting head 15 is arranged inside the vertical opening groove 303, and a first R pin 305 is inserted inside the waist-shaped opening groove 302.

[0034] In the present invention, the assembly principle of the modular insulator element is as follows: when the number of modular insulator elements needs to be increased, it is only necessary to align the connector of the added modular insulator element with the waist-shaped opening groove and the connecting rod with the vertical opening groove, and then push it into the interior of the mounting seat so that the connector falls into the first slot and is clamped. At this time, the connecting rod falls into the vertical opening groove. Since the diameter of the connecting rod matches the opening size of the vertical opening groove, and the diameter of the connecting head is larger than the connecting rod and smaller than the opening size of the waist-shaped opening groove, the connecting head can be stably clamped into the first slot and will not move toward the vertical opening groove. Then, the first R pin is inserted into the waist-shaped opening groove from the back of the mounting seat and is located below the connecting head, limiting the movement of the connecting head toward the waist-shaped opening groove, and further stably and reliably clamping the connecting head into the first slot, thereby realizing the assembly of modular insulator elements, facilitating the increase or decrease of their number according to actual needs, so that the insulator string can be suitable for different usage scenarios.

[0036] In the present invention, the working principle of the installation component is as follows: the connection process between the installation component and the modular insulator element at the bottom of the insulator string is similar to the connection operation between the modular insulator elements. For details, reference can be made to the connection operation between the above-mentioned modular insulator elements. The connector is inserted into the second slot, and then the second R pin is inserted from the back of the first U-shaped seat into the first rectangular slot and is located below the connector, restricting the connector from moving toward the first rectangular slot, and further stably and reliably inserting the connector into the second slot, thereby realizing the connection between the insulator string and the installation component, and then the overall installation and fixation of the insulator string is realized through the cooperation of the mounting plate and the mounting bolts.

[0037] The wire fixing assembly 3 includes a second U-shaped seat 31, a second rectangular slot 32 is provided on the upper part of the second U-shaped seat 31, a second longitudinal slot 33 is provided at the lower part of the second rectangular slot 32, a third clamping slot 34 is provided inside the second longitudinal slot 33, and a third R plug 35 is inserted inside the second rectangular slot 32; a clamping ball head 38 is clamped inside the third clamping slot 34, and a hanging ring 39 is provided below the clamping ball head 38, which is clamped with the first clamping slot 304 and fixedly connected with the first R plug 305; bowl head wire fixing hanging plates 36 are provided on both sides above the second U-shaped seat 31, and wire fixing bolts 37 are provided inside the bowl head wire fixing hanging plates 36.

[0038] In the present invention, the working principle of the wire fixing component is as follows: the connection process between the clamping ball head of the wire fixing component and the second U-shaped seat is similar to the connection operation between the installation component and the modular insulator element at the bottom of the insulator string. For details, please refer to the connection operation between the installation component and the modular insulator element at the bottom of the insulator string mentioned above, clamp the clamping ball head into the third clamping groove, and then insert the third R pin from the back of the second U-shaped seat into the second rectangular slot and be located above the clamping ball head, restricting the clamping ball head from moving toward the second rectangular slot, and further stably and reliably clamping the clamping ball head into the third clamping groove; then push the hanging ring into the waist-shaped opening groove of the modular insulator element at the top of the insulator string, at this time, the rod connecting the hanging ring and the clamping ball head falls into the vertical opening groove, and then insert the first R pin from the back of the installation seat into the waist-shaped opening groove and penetrate the hanging ring and then lock it, thereby realizing the connection between the insulator string and the wire fixing component, and then the support and fixation of the cable are realized through the cooperation of the bowl head wire fixing hanging plate and the wire fixing bolt.

[0039] The present invention is a modular insulator that is easy to install. During use, the present invention fixes and installs the insulator string 1 as a whole through the installation component 2; the cable is clamped by the wire fixing component 3 to fix the cable during the process of fixing it to the cable, which is simple and convenient to operate and improves work efficiency; the present invention can increase or decrease the number of modular insulator elements 100 according to specific conditions in reality, and can adjust the overall length of the insulator string 1 according to actual needs, thereby improving the application effect of the insulator in different scenarios; the present invention adopts a plurality of modular insulator elements 100 to form the overall structure of the insulator string 1, which is convenient for timely and rapid replacement of individual modular insulator elements 100 that cannot be used or have poor use effects due to damage or insufficient insulation capacity, thereby avoiding the situation where the modular insulator element 100 is damaged and cannot be maintained and installed, and also avoiding the high cost of disassembling the insulator string 1 as a whole; the present invention has the advantages of reasonable structure, modular structure, reduced cost and workload, and convenient and quick disassembly and replacement. Example

[0040] like Figure 9-12As shown, an auxiliary spreading tool for a modular insulator that is easy to install is used to realize the auxiliary function of the disassembly, assembly and replacement of the modular insulator that is easy to install as described above, including a disassembly and assembly auxiliary spreading component 4, the disassembly and assembly auxiliary spreading component 4 includes an upper clamp 41 and a lower clamp 42 with the same structure, and clamp connectors 43 are installed on both sides of the upper clamp 41 and the lower clamp 42, and the clamp connectors 43 are movably connected to the corresponding upper clamp 41 and lower clamp 42 through a hinge 44 of a U-shaped structure, and a screw sleeve 45 is installed on the inner side of the clamp connector 43, and a screw 46 is installed inside the screw sleeve 45, and a manual component 47 is installed in the middle of the screw 46, and a manual rod 48 is provided on the outer side of the manual component 47.

[0041] The upper clamp 41 includes a semicircular fixed clamp 101, and both sides of the fixed clamp 101 are provided with hinged ends 102 hingedly connected to the hinge head 44. A semicircular movable clamp 103 is provided in front of the fixed clamp 101, and one side of the movable clamp 103 is rotatably connected to the fixed clamp 101 through an axis rod 104, and the other side is provided with a connecting end 107; the fixed clamp 101 is provided with a movable bolt 106 threadedly connected to the connecting end 107 on one side corresponding to the connecting end 107, and the movable bolt 106 is movably fixed to the fixed clamp 101 through a pin 105.

[0042] The manual assembly 47 includes a positioning ring sleeve 71 and a rod sleeve 72. The positioning ring sleeve 71 and the rod sleeve 72 are an integrally formed structure and a Y-shaped opening 73 is provided at the connection between the rod sleeve 72 and the positioning ring sleeve 71. A positioning ring 74 is provided above the positioning ring sleeve 71. The positioning ring 74 is connected to the positioning ring sleeve 71 through a plurality of slotted cylindrical head screws 75. A positioning tooth sleeve 76 is provided inside the positioning ring sleeve 71 and is sleeved on the outside of the lead screw 46.

[0043] A limit buckle 77 movably engaged with the positioning gear sleeve 76 is arranged inside the Y-shaped opening 73, and the limit buckle 77 is connected to the rod sleeve 72 through a slotted flat-end set screw 78. A positioning pin 79 is arranged on the outside of the limit buckle 77, and a slotted concave-end set screw 702 is arranged on the outside of the positioning pin 79. The slotted concave-end set screw 702 is connected to the positioning pin 79 through a spring 701.

[0044] In the present invention, the working principle of the disassembly and assembly auxiliary expansion assembly is as follows: when the modular insulator elements of the insulator string need to be installed, it is only necessary to open the corresponding movable clamps of the upper clamp and the lower clamp in sequence, such as Fig.11As shown; then the connecting fittings of the modular insulator are dropped into the movable space formed by the movable clamp and the fixed clamp, and then the movable clamp is closed, and the movable clamp is reliably connected to the fixed clamp through the joint bolt and the connection end, so that the corresponding modular insulator elements are reliably and effectively clamped and fixed by the upper clamp and the lower clamp, as shown in FIG. Fig. 9 As shown; the manual assembly is then driven to move by the manual rod, and the manual assembly drives the fixture connectors to move closer to or farther from each other through the lead screw sleeves on the upper and lower sides through the lead screw, thereby adjusting the spacing between the upper fixture and the lower fixture, thereby realizing the assembly work between the modular insulator components; of course, the overall disassembly of the insulator string or the disassembly of a certain modular insulator component can also be realized, and the disassembly and assembly are convenient and fast, and the use is relatively simple and convenient, saving time and effort; The specific working process of the manual assembly is as follows: when the rod sleeve and the positioning ring sleeve are driven to rotate by the manual rod, the positioning ring sleeve drives the screw rod to rotate through the positioning tooth sleeve inside it. When adjusted to the right position, the slotted flat end set screw is adjusted to drive the limit buckle to rotate, so that the limit buckle as a whole deviates to one side and the claw of the limit buckle is clamped with the positioning tooth sleeve, such as Fig.12 As shown, at this time, the limit buckle realizes effective and reliable locking of the positioning tooth sleeve under the cooperation of the positioning pin, the spring and the slotted concave end set screw, ensuring the overall stability and reliability of the disassembly and assembly auxiliary expansion assembly during use; Of course, in actual use, the slotted flat-end locking screw can also be replaced by a pin shaft with a torsion spring and a limit buckle, so that the limit buckle and the positioning gear sleeve form a structure similar to the ratchet pawl to realize its unidirectional rotation function, and the positioning pin, spring and the slotted concave-end locking screw cooperate to form a limit assembly of the ratchet pawl. When it is necessary to drive the lead screw to rotate in the opposite direction through the positioning gear sleeve, since the positioning ring sleeve and the rod sleeve are an integrally formed structure and a Y-shaped opening is provided at the connection between the rod sleeve and the positioning ring sleeve, and the limit buckle is located in the Y-shaped opening, it is only necessary to press one end of the limit buckle (the end of the limit buckle that is not in contact with the positioning ring sleeve) to make the other end of the limit buckle (the end of the limit buckle that is in contact with the positioning ring sleeve) rise, so that the limit buckle releases the locking state of the positioning ring sleeve, and the reverse rotation function can be realized; the present invention only introduces another structure that can realize the corresponding function. Of course, there are other structures that can also realize the corresponding function, and the present invention will not introduce them one by one here.
