Description

Technical Field

[0001] The invention relates to the technical field of electric power maintenance, and in particular to a deformation monitoring and early warning device for an insulating soft sling based on sensor monitoring. Background Art

[0002] During live maintenance of extra-high voltage and ultra-high voltage transmission lines, it is often necessary to replace insulator strings weighing hundreds of kilograms or other equipment at an altitude of tens of meters above the ground in an electric field environment of one million volts. In the past, weighing equipment was needed to support such operations. The existing supporting equipment uses an insulating hard hanger made of composite materials, but the hanger is long and heavy, which is inconvenient in storage, transportation and use. Therefore, an insulating soft sling is needed. After searching, it is found that the sling in the prior art is typically an insulating sling such as publication number CN103485070A, which includes a hanging plate, a connecting ring, a hook, a second triangular hook and a circular hanging ring; the hanging plate and the first triangular hook are connected by a connecting ring; the first triangular hook and the second triangular hook are respectively arranged at both ends of the sling; one end of the second triangular hook is connected to the circular hanging ring. The main features of the insulating sling and the manufacturing method of the sling of the present invention are: 1. The insulating sling is reasonably designed, has a simple structure, saves time in processing, is easy to assemble, and is fast and convenient to use and move, thereby improving work efficiency; 2. The insulating sling is wear-resistant, effectively prolongs its service life, reduces the use and maintenance costs and production cost investment, ensures the life safety of construction personnel, and prevents the occurrence of safety accidents.

Its main feature is that it can perform remote detection of the use status of the insulating sling.

[0004] In summary, the existing slings mainly detect the total stretching length of the device through infrared ranging sensors, but are unable to detect other deformation phenomena when the slings are working, that is, are unable to further refine their working status. In view of the above problems, the existing equipment needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a deformation monitoring and early warning device for an insulating soft sling based on sensor monitoring, so as to solve the problem that the existing slings proposed in the above background technology mainly detect the total stretching length of the device as a whole through infrared ranging sensors, but cannot detect other deformation phenomena when the sling is working, that is, cannot further refine and control its working state.

[0006] To achieve the above object, the present invention provides the following technical solution: a deformation monitoring and early warning device for an insulating soft sling based on sensor monitoring, comprising a soft maintenance sling, a flexible sensor module and a connector,

[0007] A flexible sensor module is arranged on one side of the soft maintenance sling, and the flexible sensor module includes a first detection fiber grating, a second detection fiber grating, a composite coating, an insulating sleeve, reinforcing ribs, a glue storage groove and a protective installation sleeve. The first detection fiber grating and the second detection fiber grating are both provided with reinforcing ribs on the upper and lower sides, and the first detection fiber grating, the second detection fiber grating and the reinforcing ribs are all arranged inside the protective installation sleeve. At the same time, a glue storage groove is opened on one side wall of the protective installation sleeve. The outer sides of the first detection fiber grating and the second detection fiber grating are coated with a composite coating, and the outer side of the composite coating is wrapped with an insulating sleeve. At the same time, the first detection fiber grating and the second detection fiber grating are connected to the regulator.

[0008] Preferably, both ends of the soft maintenance sling are fixedly connected with mounting seats, and a slot is provided on a side wall of the mounting seat away from the soft maintenance sling.

[0009] Preferably, a distance measuring sensor device is arranged on a side wall of the soft maintenance sling away from the flexible sensor module, and the distance measuring sensor device includes an infrared distance measuring module and an infrared receiving module, and the infrared distance measuring module and the infrared receiving module are arranged relatively.

[0010] Preferably, the composite coating includes an anti-corrosion coating, a wear-resistant coating and a high-temperature resistant coating, and the anti-corrosion coating, the wear-resistant coating and the high-temperature resistant coating are distributed in sequence from the inside to the outside.

[0011] Preferably, two groups of reinforcing ribs are provided, and the reinforcing ribs are evenly spaced and distributed on the upper and lower sides of the first detection fiber grating and the second detection fiber grating.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the deformation monitoring and early warning device of the insulating soft sling based on sensor monitoring,

[0018] (1) The present invention can effectively solve the problem that the existing sling mainly detects the total length of the stretch of the entire device through the infrared distance measuring sensor, but cannot detect other deformation phenomena when the sling is working, that is, it is impossible to further refine and control its working state. The first detection fiber grating and the second detection fiber grating detect the deformation amount generated when the soft maintenance sling is working, and upload the detected data to the system terminal device through the regulator, that is, the staff can check the working state of the soft maintenance sling through the system terminal device, thereby further improving the intelligence level of the soft maintenance sling. In addition, the staff can check the stretching amount of different positions of the soft maintenance sling by checking the measured distance of the distance measuring sensor device at different positions, thereby avoiding the breakage due to excessive stretching deformation of a certain part.

[0019] (2) The present invention can effectively solve the problem that most of the existing slings have an integrated structure, that is, when the joints at both ends of the slings for connecting to the external structure are damaged or unsuitable, the device needs to be replaced as a whole, resulting in poor flexibility and high maintenance costs. When the connector is damaged or the assembly holes of different sizes on the connector are unsuitable for current use, the staff can separate the connector from the mounting base by disassembling the studs, and then replace the connector. The disassembly and replacement work is relatively convenient and quick, and the maintenance cost is lower than that of overall replacement. BRIEF DESCRIPTION OF THE DRAWINGS
