Description

Technical Field

[0001] The utility model relates to the technical field of power monitoring, in particular to a rail-mounted instrument and a power safety online monitoring device. Background Technique

[0002] To ensure the normal operation of the power system, in the power system, a multi-functional power meter is usually connected and installed to monitor the power parameters of the power system (such as power consumption and power factor, etc.) in real time. When the existing multi-functional power meters are actually installed, they are mainly installed through a rail-mounted structure. The existing rail-mounted structure of the multi-functional power meter mainly uses an elastic card to achieve installation and fixation. In the actual use process, when the multi-functional power meter needs to be disassembled for later maintenance and repair, it is easy to cause damage to the elastic card, thus affecting the normal use of the multi-functional power meter. Moreover, when the existing multi-functional power meters are wired, there is a lack of a guiding structure. When tidying up the wires later, there will be a certain bend between the wires and the multi-functional power meter, which is easy to cause deformation and damage to the wiring part. Therefore, in view of the above problems, a rail-mounted instrument and a power safety online monitoring device are designed now to better meet the actual use requirements.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a rail-mounted instrument and power safety online monitoring device, including a guide rail body 1 and a multifunctional power meter 2, the guide rail body 1 is connected to the multifunctional power meter 2, a wiring hole 3 is opened on the multifunctional power meter 2, the lower end of the multifunctional power meter 2 is connected to a threaded rod 4 by a bearing, the threaded rod 4 is connected to the movable plate 5 by a thread, the movable plate 5 is arranged inside the multifunctional power meter 2, a top plate 6 is arranged at the rear of the multifunctional power meter 2, and fixed rods 8 are symmetrically fixed on the left and right sides in front of the multifunctional power meter 2.

[0018] A display screen 201 is installed on the multifunctional power meter 2, and control buttons 202 are also installed on the multifunctional power meter 2. A fixed card strip 203 is fixed on the rear end face of the multifunctional power meter 2, and the fixed card strip 203 is in snap connection with the guide rail body 1; a movable card strip 501 is fixed on the movable plate 5, and the movable card strip 501 is in sliding connection with the multifunctional power meter 2, and the movable card strip 501 is in snap connection with the guide rail body 1. A vertical rod 502 is also fixed on the movable card strip 501;

[0019] When using this rail-mounted instrument, such as Figures 1 - 3As shown in the figure, first, install the multifunctional power meter 2. The positioning of the multifunctional power meter 2 can be achieved by engaging the fixing strip 203 with the guide rail body 1. At this time, the fixing strip 203 can slide relative to the guide rail body 1, which is convenient for adjusting the installation position of the multifunctional power meter 2. After the adjustment is completed, by rotating the threaded rod 4, the movable plate 5 can be forced to move upward, thereby driving the movable strip 501 to move, realizing the adjustment of the distance between the movable strip 501 and the fixing strip 203. When the movable strip 501 engages with the guide rail body 1, the fixing of the multifunctional power meter 2 can be achieved, facilitating the installation of the multifunctional power meter 2.

[0020] A rubber pad 101 is fixed on the guide rail body 1, and the rubber pad 101 is located between the multifunctional power meter 2 and the guide rail body 1. Anti-slip teeth 601 are uniformly fixed on the rear side of the top plate 6, and the anti-slip teeth 601 can achieve a positioning effect when contacting the rubber pad 101. A sliding rod 602 is fixed on the front side of the top plate 6, and the sliding rod 602 is slidably connected to the multifunctional power meter 2.

[0021] When the movable plate 5 is forced to move, as Figures 1 - 3 shown in the figure, at this time, the connecting rod 7 is forced to rotate. Through the transmission of the connecting rod 7, the sliding rod 602 can be forced to slide backward, thereby driving the top plate 6 and the anti-slip teeth 601 to move backward. When the movable strip 501 engages with the guide rail body 1, at this time, the anti-slip teeth 601 contact the rubber pad 101 and generate a certain pressure on the rubber pad 101, so that a large frictional force is generated between the anti-slip teeth 601 and the rubber pad 101, and then the positioning effect of the multifunctional power meter 2 can be achieved, avoiding the sliding of the multifunctional power meter 2 and ensuring the stability of the installation of the multifunctional power meter 2. Finally, the wire is matched with the wiring hole 3, and the wire is fixed by bolts to achieve the wiring function.
