Description

Technical Field

[0001] The utility model relates to the technical field of electrified railway contact network monitoring, and provides a contact network insulator state detection device. Background Art

[0002] The contact network insulator is an important electrical equipment in the electrified railway. It is used to support the contact wire and maintain electrical isolation from the ground. The state of the contact network insulator directly affects the safe operation of the contact network. Therefore, it is very necessary to detect the state of the insulator in a timely manner and take corresponding maintenance measures. At present, there are two main ways to detect the state of the contact network insulator: one is manual inspection, that is, professionals regularly conduct visual inspections of the contact network insulators, find abnormal or damaged insulators and replace them in time; the other is machine inspection, that is, use various detection equipment and sensors to perform automatic or semi-automatic inspections on the contact network insulators, obtain various parameters and characteristics of the insulators, and analyze and evaluate them.

[0003] In the prior art, the Chinese invention patent with publication number CN107515351A includes a collector and a leakage current detection module; a solar panel is installed on the collector, and the collector is fixed to a pillar or a structural support by U-bolts and screws. The above patent detects the state of the insulator through the collector and the leakage current detection module, and supplies power to the above device through the solar panel. However, it can be seen from the patent that the solar panel is fixed on one side of the pillar, and the conversion efficiency of the solar panel is limited by the position of the pillar and the collector. If the pillar is located on the south side of the collector, the solar panel is blocked by the pillar. The conversion efficiency of the solar panel is limited by the position of the pillar and the collector. This is because the lighting angle and area of ​​the solar panel directly affect its conversion efficiency. If the pillar is located on the south side of the collector, the solar panel will be blocked by the pillar within a certain period of time and cannot fully receive sunlight. In addition, even if the solar panel is not blocked by the pillar, the tilt angle of the solar panel also affects its conversion efficiency. Only by ensuring that the solar panel can face the sun can the utilization rate of the solar panel be guaranteed.

[0004] Therefore, it is urgent to redesign the insulator monitoring device of the contact network system to solve the above problems. Summary of the invention

The two sides of the sliding block 54 are provided with a rotating shaft 1 541 that cooperates with the swing arm 53. The middle part of the rotating plate 52 is provided with a connecting protrusion 521, and the two sides of the protrusion are provided with a rotating shaft 2 522 that rotatably matches with the swing arm 53. The front end of the rotating plate 52 is rotatably matched with the front end of the fixed plate 51, and the two sides of the front end of the fixed plate 51 are provided with a rotating shaft 3 512.

The rotating support protrusion 523 extends downward for a distance from the lower side of the front end of the rotating plate 52. The solar panel 42 is fixed on the rotating plate 52, so that the solar panel 42 can adjust the tilt angle according to the rotation of the screw 55, so that the solar panel 42 can receive more sunlight. This device is different from the conventional damping rotation tilt. Because this device is used outdoors, it needs to be as impervious to wind and rain impact. Therefore, the use of this device can ensure the service life and stability.

[0046] As a further optimization, Figure 1 and Figure 5 As shown in FIG. 2 , in order to ensure that the solar panel 42 can face south when the device is installed on railways in different directions, the fixing plate 51 of the device is designed to be adjustable on the housing 41. The fixing plate 51 is provided with two parallel bolt grooves 513, and the housing 41 is provided with four bolts arranged in a square to cooperate with the bolts. As shown in FIG. 2 , the device is located on the left side of the column 1. When the south is on the left side of the column 1, the device can be as shown in FIG. Figure 2 When the south is located above and below the column 1 as shown in 3, the Figure 2The installation shown is performed by rotating the solar panel 42 by 90 degrees to ensure that the solar panel 42 can face the sun directly.

The fixing frame 6 designed as above is simple to install and has a stable structure.

[0048] Meanwhile, in some embodiments, the horizontal plate 611 is provided with two parallel bolt grooves 6111, the fastening frame 63 includes a long strip-shaped plane plate 631 and a vertical rod 633, the plane plate 631 is provided with two parallel bolt grooves 632, the plane plate 631 and the horizontal plate 611 are fixed by two bolts passing through the corresponding bolt grooves 6111 and 632, the lower end of the vertical rod 633 is fixed to the middle of the plane plate 631, and the upper end of the vertical rod 633 is fixedly connected to the shell 41. Because the direction of some railways is not due south or east, and the angle between them and due south is not 90 degrees, the horizontal plate 611 can be tilted at a certain angle in advance when installing the horizontal plate 611, so as to ensure that the solar panel 42 located on the shell 41 can face the sun directly. And through this design, when the aggregation device 4 is located on the north side of the column 1, the sunlight is blocked by the column 1, which can be as shown Figure 6 As shown, only one end of the horizontal plate 611 is fixed so that the aggregation device 4 is free from the obstruction of the column 1. The device can still ensure the stability of its installation.
