Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology, specifically to an auxiliary device for intelligent substations. Background Technology

[0002] With economic development and rising electricity consumption levels, social electricity consumption is constantly increasing, posing greater challenges to the safe and stable operation of the power grid. As a crucial link in the power system, substations are facing increasing inspection demands. In recent years, with the introduction of the smart grid concept, intelligent substation inspection systems have seen unprecedented development. Compared to traditional manual inspection methods, these systems utilize various intelligent detection devices to intelligently identify and link equipment within the station, reducing the workload of maintenance personnel and improving inspection efficiency to some extent. However, the intelligent inspection system at the Chenjiaqiao Maintenance Station of the Chengxi Substation Maintenance Center of the State Grid Chongqing Electric Power Company's Ultra-High Voltage Branch has a low accuracy rate in providing inspection results. Tracking failed inspection points still requires manual inspection, forcing maintenance personnel to travel extensively throughout the switchyard, increasing their burden. Analysis reveals that one of the factors currently hindering the efficiency of intelligent inspection is that weather or lighting conditions prevent some meters from being clearly captured by cameras, thus hindering data reading and impacting inspection efficiency.

[0003] A prior art patent, CN218633047U, describes a solution comprising a protective cover detachably mounted on the top of the meter housing and extending towards the front of the housing; a plurality of supplementary lights evenly arranged along the circumference of the meter housing; and an electronically controlled switch electrically connected to each of the supplementary lights. The supplementary lights are positioned facing the center of the meter display area in the middle of the meter housing. By providing a protective cover on the top of the meter housing, rainwater can be effectively prevented from contacting the meter, and strong light sources can be effectively blocked when the meter is exposed to direct sunlight. The supplementary lights also enhance the brightness of the meter display area, which helps the camera obtain a clear image of the meter dial.

[0004] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0005] First, existing substation instrument auxiliary observation mirrors have large horizontal protective covers to improve the sunshade effect, which increases the horizontal space of the equipment and affects the layout and use of the equipment.

[0006] Secondly, the existing instrument observation mirrors are limited by the installation structure, making them inconvenient to fix on the substation enclosure, and the operation is cumbersome, time-consuming and labor-intensive.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for intelligent substations. This device solves the problems of existing instrument observation mirrors in substations, which require a large horizontal protective cover to improve the sunshade effect, thus increasing the horizontal space of the equipment and affecting its layout and use; and existing instrument observation mirrors, due to their installation structure, are not easy to fix to the substation enclosure, resulting in cumbersome, time-consuming and labor-intensive operation.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An auxiliary device for intelligent substations includes a fixed frame with an observation hole. An LED light strip surrounds the observation hole, and an observation mirror is fixed inside the observation hole. A movable frame is swaying on the fixed frame, and a channel corresponding to the observation hole is opened on the movable frame. A magnifying glass is fixedly connected within the channel.

[0011] A ring magnet is fixed to the upper end of the fixing frame, and a suction cup is detachably connected to the inner hole of the ring magnet.

[0012] As an optimized solution, an anti-reflective film is affixed to the observation mirror.

[0013] As an optimized solution, the observation hole includes a cylindrical hole and a conical hole, with the large-diameter end of the conical hole facing the instrument, and the back of the LED light strip is glued inside the conical hole.

[0014] As an optimized solution, the upper end of the fixing frame is provided with an annular groove that matches the annular magnet, and the annular magnet is fitted into the annular groove.

[0015] As an optimized solution, the portion of the fixing frame located within the inner ring of the annular magnet has an arc-shaped mounting groove, and the back of the suction cup has a spherical protrusion that engages with the arc-shaped mounting groove.

[0016] As an optimized solution, a groove is provided on the end of the fixed frame near the swing end of the movable frame, a first magnetic absorbing piece is fixedly connected in the groove, and a second magnetic absorbing piece that cooperates with the first magnetic absorbing piece is fixedly connected to the swing end of the movable frame.

[0017] As an optimized solution, two connecting rods are fixedly connected side by side to the upper end of the movable frame, and the upper ends of the two connecting rods are respectively hinged to the opposite end faces of the fixed frame.

[0018] As an optimized solution, a positioning knob is threaded onto one of the connecting rods, and a positioning groove is provided on the upper end face of the fixed frame at the hinge center of the connecting rod. When the movable frame swings to the upper position, the end of the positioning knob abuts against the positioning groove.

[0019] As an optimized solution, the observation mirror is fixed inside the cylindrical hole.

[0020] As an optimized solution, the mounting bracket is provided with a power module placement slot in the area above the observation hole, and a cover plate that engages with the power module placement slot is provided on the front of the mounting bracket.

[0021] As an optimized solution, a lighting switch is provided in the area above the power module placement slot of the mounting bracket.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

When the outer surface of the enclosure is relatively smooth, the spherical protrusion on the back of the suction cup can be inserted into the arc-shaped mounting groove, and the accessory can be fixed to the instrument opening of the enclosure using the suction cup. This provides multiple fixing methods and is convenient to install and remove.

[0024] By setting up a magnifying glass, the smaller readings on the instrument panel can be clearly observed with the help of a rotating bracket, making it convenient and quick.

[0025] By setting a conical hole, the back of the LED light strip is glued to the conical hole, which allows the LED light strip to be set at an angle and illuminate the instrument surface. This helps to improve the brightness of the instrument surface, improve the clarity of observation, and facilitate reading.

[0026] By attaching an anti-reflective film to the observation mirror, the influence of strong external light on the observation mirror can be reduced, further improving the clarity of the reading. Attached Figure Description

Detailed Implementation

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0031] like Figure 1 As shown, the auxiliary device for intelligent substations includes a fixed frame 1, an observation hole on the fixed frame 1, an LED light strip 3 surrounding the observation hole, and an observation mirror 4 fixed inside the observation hole. A movable frame 2 is oscillating on the fixed frame 1, and a channel corresponding to the observation hole is opened on the movable frame 2, with a magnifying glass 6 fixedly connected inside the channel.

[0032] A ring magnet 9 is fixedly attached to the upper end of the fixing frame 1, and a suction cup 10 is detachably connected to the inner hole of the ring magnet 9.

[0033] An anti-reflective film 5 is affixed to the observation mirror 4.

[0034] The observation hole includes a straight cylindrical hole and a conical hole. The large diameter end of the conical hole faces the instrument, and the back of the LED light strip 3 is glued inside the conical hole.

[0035] The upper end of the fixing frame 1 is provided with an annular groove that matches the annular magnet 9, and the annular magnet 9 is fitted into the annular groove.

[0036] The part of the fixing bracket 1 located in the inner circle of the annular magnet 9 has an arc-shaped mounting groove, and the back of the suction cup 10 has a spherical protrusion 11 that is mounted in the arc-shaped mounting groove.

[0037] A groove is provided on the end of the fixed frame 1 near the swing end of the movable frame 2. A first magnetic piece 7 is fixedly connected in the groove. A second magnetic piece 8 that cooperates with the first magnetic piece 7 is fixedly connected to the swing end of the movable frame 2.

[0038] Two connecting rods 12 are fixedly connected side by side to the upper end of the movable frame 2, and the upper ends of the two connecting rods 12 are respectively hinged to the opposite end faces of the fixed frame 1.

[0039] One of the connecting rods 12 is threaded with a positioning knob 13. The fixed frame 1 has a positioning groove 14 on the upper end face of the connecting rod 12 at the hinge center. When the movable frame 2 swings to the top, the end of the positioning knob 13 abuts against the positioning groove 14, which can fix the movable frame 2 when it is not in use.

[0040] The observation mirror 4 is fixed inside the straight cylindrical hole.

[0041] The mounting bracket 1 has a power module placement slot 15 in the area above the observation hole, and a cover plate 16 that is snapped into the power module placement slot 15 on the front side of the mounting bracket 1.

[0044] The working principle of this device is as follows:

[0045] By setting an annular magnet 9 on the fixing frame 1, when the box is made of iron, the annular magnet 9 can be used to quickly fix the auxiliary tool to the position of the instrument. When the outer surface of the box is relatively smooth, the spherical protrusion 11 on the back of the suction cup 10 can be snapped into the arc-shaped clamping groove, and the auxiliary tool can be fixed to the instrument opening of the box using the suction cup 10. This provides multiple fixing methods and is convenient to install and remove, making it easy to use.

[0046] By setting up a magnifying glass 6, the smaller readings on the instrument panel can be clearly observed with the help of the magnifying glass 6 by flipping the movable bracket 2, which is convenient and quick.

[0047] By setting a conical hole, the back of the LED light strip 3 is glued to the conical hole, so that the LED light strip 3 can be tilted and illuminated towards the instrument surface. This can help improve the brightness of the instrument surface, improve the clarity of observation, and facilitate reading.

[0048] By attaching an anti-reflective film 5 to the observation mirror 4, the influence of strong external light on the observation mirror 4 can be reduced, further improving the clarity of the reading.

[0049] This auxiliary device eliminates the need for a protective cover in traditional technology, which can reduce the lateral space of the equipment and facilitate its spatial layout.
