Description

Technical Field

[0001] The utility model belongs to the technical field of power system automation, and in particular relates to a low-voltage live power taking device based on a fixed arm. Background Art

[0002] In recent years, the power Internet of Things (IoT) has flourished in the pursuit of building a world-class smart grid. While medium-voltage automation has begun to take shape in the power distribution sector, low-voltage distribution automation is still in its infancy. To address this massive market, a large number of intelligent devices need to be empowered to power traditional, non-intelligent equipment, such as station buildings, distribution transformers, low-voltage switches, branch boxes, and meter boxes.

[0003] The prior art patent announcement number CN113834962A is a low-voltage live power-taking device based on a fixed arm. The above patent includes a fixed arm and a power-taking pole connected to the end of the fixed arm. The fixed arm includes a main body, and the two sides of the main body extend outward to form two horizontal side panels. Each side panel has two long strip-shaped through holes, and a wire hole is provided inside the main body; the power-taking pole includes an outer shell, a fixing ring inside the outer shell, a knob, a hexagonal bolt head embedded in the knob, a first stud connected below the hexagonal bolt head, a second stud below the first stud, and a spring sleeved on the outside of the second stud. In the present invention, a spring sleeve is provided on the outside of the second stud of the power-taking pole. Crab, the contact area with the power-taking part can be increased by the spring, and the power-taking device can be tightly combined with the power-taking part of the power-taking cable through elastic action, so that it can be stably connected even when subjected to vibration, and can achieve live power taking. However, there are still the following deficiencies in actual use: From a practical point of view, the device only uses cable ties to limit the cable during the process of threading the power-taking cable to take power. When taking power through the power-taking pole, the cable is prone to loosening, which affects the stability of its connection and reduces the power-taking efficiency. At the same time, it cannot be adjusted accordingly according to the power-taking position, resulting in poor cable limit adjustment ability, further reducing its stability.

[0004] Therefore, a low-voltage live power taking device based on a fixed arm is needed to solve the problem in the prior art that the power taking cable has poor stability after being limited and is inconvenient to adjust. Utility Model Content

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-4 The utility model provides a low-voltage live power taking device based on a fixed arm, comprising a first fixed arm 1, a second fixed arm 2 and a power taking pole device 4, the power taking pole device 4 is fixedly connected to the right side of the second fixed arm 2, the first fixed arm 1 is arranged on the left side of the second fixed arm 2, a locking belt 101 is tied on the first fixed arm 1, a wire threading hole 102 is opened on the inner side of the upper part of the first fixed arm 1, a limiting block 103 is fixedly connected to the bottom surface of the first fixed arm 1, and a connecting arm 104 is fixedly connected to the right side of the bottom of the first fixed arm 1, a limiting mechanism 3 is provided on the second fixed arm 2, and the power taking cable passing through the wire threading hole 102 is limited by the connecting arm 104, and the connecting arm 104 is matched with the inner wall of the second fixed arm 2.

[0023] The first fixed arm 1 and the power taking pole device 4 have been specifically disclosed in the invention patent with patent publication number CN113834962A, and will not be described in detail here.

[0024] Further as Figure 1 、 Figure 2 and Figure 3As shown, it is worth mentioning that the front and rear sides of the second fixed arm 2 are fixedly connected to the limit frame 201 and are symmetrically arranged. The limit frame 201 is fixedly connected to the right side surface of the first fixed arm 1 with a connecting rod 202. The first fixed arm 1 is slidably arranged in the limit frame 201 through the connecting rod 202, and a through connecting hole 203 is opened on the upper part of the second fixed arm 2 to match the threading hole 102.

[0025] During use, the power cable is passed through the wire hole 102, the connecting hole 203 and the through hole 302 to be electrically connected to the power pole device 4, so that the power-taking operation can be achieved by operating the power pole device 4. At the same time, by sliding the second fixed arm 2, since the connecting rod 202 slides in the limit frame 201, the connecting arm 104 slides at the bottom of the second fixed arm 2, so that the power pole device 4 can be adjusted in position through the second fixed arm 2, thereby facilitating the power-taking operation adjustment work according to the position of the power cable, thereby improving its practicality.

[0026] According to the above working process, it can be seen that: by setting the first fixed arm 1 in conjunction with the second fixed arm 2, the second fixed arm 2 can be adjusted to a certain position according to the power-taking position of the power-taking pole device 4, so as to facilitate the matching limiting work of the power-taking cable, thereby improving its practicality and ease of use.

[0027] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the limiting mechanism 3 includes a limiting plate 301, which is fixedly connected to the right side surface of the connecting arm 104 and is arranged at the bottom of the second fixed arm 2.

A slider 305 is slidingly provided in the sliding groove 304. The left end of the slider 305 is fixedly connected to an extrusion block 307.

[0030] In summary: by setting the first fixed arm 1 in conjunction with the second fixed arm 2, the second fixed arm 2 can be adjusted to a certain position according to the power-taking position of the power-taking pole device 4, so as to facilitate the matching limiting work of the power-taking cable, thereby improving its practicality and ease of use; by setting the limiting mechanism 3, when the power-taking cable passes through the wire hole 102 and is connected to the power-taking pole device 4, the power-taking cable can be stably limited and fixed, thereby improving the stability of the cable during the power-taking process, so as to improve its safety in use.
