Description

Technical Field

[0001] This utility model relates to the technical field of distribution network traveling wave fault early warning and location device, and in particular to an early warning and fault diagnosis device for new energy operation and maintenance management. Background Technology

[0002] Wind farms are a crucial part of new energy operation and maintenance management. Due to the long distances of wind farm collection lines and the complex natural environment, they are susceptible to factors such as lightning strikes, icing, and bird damage, resulting in a high line tripping rate. Collection line fault early warning and diagnosis systems, through traveling wave monitoring technology, can quickly and accurately locate faults, shorten fault investigation and recovery time, and improve the reliability and security of power transmission. Monitoring terminals are generally installed in a distributed manner on transmission line conductors. During installation, manual high-altitude work is usually required to install the diagnostic device on the cable. Existing diagnostic devices are generally cumbersome to install and connect. When working at height, the cumbersome installation undoubtedly increases the workload and psychological pressure on the installers. Based on this, an early warning and fault diagnosis device for new energy operation and maintenance management is proposed. Utility Model Content

[0004] This utility model is achieved using the following technical solution: an early warning and fault diagnosis device for new energy operation and maintenance management, including a lower housing, with limiting platforms fixedly connected to both upper sides of the lower housing, and limiting grooves formed on each limiting platform. A rubber push block is slidably connected inside one of the limiting grooves, and the rubber push block is used to fix the cable. A push block driving mechanism is provided on the limiting platform to make the rubber push block reciprocate along the inner side of the limiting groove. A cable fixing mechanism is provided on the lower housing.

[0005] As a further improvement to the above solution, the push block driving mechanism includes a load-bearing plate fixedly connected to the upper side of the rubber push block, the load-bearing plate being slidably connected to the inner side of the limiting groove, and a screw driving mechanism being provided on the load-bearing plate.

[0006] As a further improvement to the above solution, the screw drive mechanism includes a second bolt that is rotatably connected to the limiting platform, and the second bolt is threadedly connected to the load-bearing plate.

[0007] As a further improvement to the above solution, the cable fixing mechanism includes an upper housing rotatably connected to one side of the lower housing. Both the upper housing and the lower housing are provided with cable adapter grooves. Two limiting platforms on each side are located on both sides of the cable adapter groove. A connecting plate fixing mechanism is provided on the upper housing.

[0008] As a further improvement to the above solution, a solar panel is fixedly connected to the upper side of the upper housing.

[0009] As a further improvement to the above solution, the connecting plate fixing mechanism includes multiple clamping plates fixedly connected to the lower side of the upper housing. Each clamping plate has a clamping hole, and a clamping plate fixing mechanism for positioning the clamping plates is provided on one side of the lower housing.

[0010] As a further improvement to the above solution, the card fixing mechanism includes multiple threaded sleeves fixedly connected to one side of the lower housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model fixes the high-altitude cable by clamping it in the cable adapter groove between the lower and upper housings, and then by rotating the second bolt, pushing the rubber push block to one side so that the rubber push block abuts against the side surface of the cable. In addition, by rotating the first bolt, one end of the first bolt is inserted into the locking hole to achieve a locking fixation, which facilitates the quick installation and deployment of the operation and maintenance diagnostic device by high-altitude workers.

[0014] 2. After the upper shell of this utility model is connected to the upper shell, the limiting platform used to fix the cable and the entire push block drive mechanism will be placed inside the upper shell, which can avoid corrosion and damage from extreme outdoor environments and significantly extend the service life of the new energy operation and maintenance diagnostic device.
