Description

Technical Field

[0001] This utility model relates to the field of safety management technology for energy storage power stations, and specifically to a safety inspection system for energy storage power stations. Background Technology

[0002] As the core area for power conversion and distribution, the safe and stable operation of the power distribution room in an energy storage power station directly affects the reliability of the entire energy storage system. This environment contains a dense array of critical equipment, including high-voltage switchgear, transformers, DC buses, and control and protection devices, which continuously generate high heat and pose a risk of partial discharge during operation. Arc faults caused by aging insulation, poor contact, or overload in the power distribution equipment can ignite a fire within seconds, and the enclosed space structure further accelerates the spread of fire and hinders manual intervention. Traditional manual inspection methods face multiple limitations: maintenance personnel must frequently enter the high-voltage environment with the risk of electric shock; the identification of potential hazards such as overheated contacts and concealed cable joints inside the cabinets relies on subjective experience; and real-time tracking of abnormal temperature rises is impossible. Therefore, developing intelligent inspection equipment with autonomous operation capabilities to continuously monitor and provide early warnings of the equipment status in the power distribution room has become a rigid requirement for preventing major electrical accidents and ensuring personnel safety.

[0003] Currently, intelligent inspection equipment has been gradually introduced into the inspection of power distribution rooms in energy storage power stations. This includes using tracked or wheeled mobile robots to replace manual labor, and employing visible light and infrared cameras to collect images and temperature data. While this approach has initially solved the basic data acquisition problem, it suffers from significant bottlenecks: the mobile robots rely on high-energy-density batteries for power, requiring 2-3 daily interruptions for charging under continuous operation. Frequent charge-discharge cycles accelerate battery aging; typically, the robot's range decreases by more than 30% after one year. More importantly, their charging process requires manual intervention to replace batteries or connect charging stations. In large energy storage stations, the time spent on charging round trips alone accounts for 15%-20% of the daily effective inspection time, severely impacting inspection efficiency. These shortcomings make it difficult for existing technology to support the core requirement of 24 / 7 continuous monitoring of power distribution rooms in energy storage power stations. Utility Model Content

[0004] This utility model aims to provide a safety inspection system for energy storage power stations, which overcomes the technical problems of existing inspection robots that rely on battery power and require frequent manual charging. The system has a simple structure and is suitable for long-term and intelligent inspection of the power distribution room area of ​​energy storage power stations. While maintaining mobility, it does not require manual charging and has high inspection efficiency.

[0005] The basic solution provided by this utility model is: a safety inspection system for an energy storage power station, including an inspection trolley and an inspection track; the inspection trolley is slidably connected to the inspection track; the inspection track includes a slide rail, a conductive strip is laid parallel to the inner side of the slide rail, and a guide groove is provided on the wing plate of the slide rail; the conductive strip is locked to the web plate of the slide rail by an insulating buckle, and the end of the conductive strip is connected to the DC bus of the power station;

[0006] The inspection trolley has guide wheels on its bottom side, which are embedded in guide grooves. The inspection trolley is also equipped with a power receiving device, an image acquisition unit, a junction box, and a motor. The image acquisition unit is used to collect inspection information. The power receiving device includes a brush arm. One end of the brush arm is equipped with a brush, and the other end is hinged to the inspection trolley through an insulated rotating shaft. The wires of the brush are directly connected to the junction box, and the junction box outputs to the motor and the image acquisition unit.

[0007] Furthermore, the inspection track is fixed to the power station wall or frame by an insulating bracket.

[0008] Furthermore, a rubber shock-absorbing pad is provided at the connection between the insulating bracket and the inspection track.

[0009] Furthermore, the conductive strip is a copper alloy conductive strip.

[0010] Furthermore, the conductive strip is covered with a U-shaped insulating protective cover, the opening of which faces the inspection trolley.

[0011] Furthermore, the brush is a copper-graphite composite brush.

[0012] Furthermore, the image acquisition unit is mounted on top of the inspection vehicle via a gimbal.

[0013] Furthermore, the gimbal is also equipped with a mechanical locking knob for fixing the setting angle of the image acquisition unit.

[0014] Furthermore, the inspection vehicle is also equipped with a positioning module.

[0015] Furthermore, the power receiving device is located at the bottom of the inspection trolley; the inspection trolley is also equipped with a pressure spring, one end of which is fixedly connected to the bottom surface of the inspection trolley, and the other end is fixedly connected to the brush arm.

[0016] The working principle and advantages of this utility model are as follows:

[0017] This utility model relates to a safety inspection system for energy storage power stations. It overcomes the technical problems of existing inspection robots that rely on battery power and require frequent manual charging. The system features a simple structure, maintains mobility, eliminates the need for manual charging, and achieves high inspection efficiency. The key points are:

[0018] First, this solution, through a continuous power supply design using "conductive strips + brushes" (the conductive strips are connected to the DC bus of the power station, and the brushes draw power in real time and supply power to the motor and image acquisition unit through a junction box), completely solves the problem of traditional inspection robots relying on battery power and requiring frequent manual charging. This achieves "uninterrupted operation" during the inspection process, significantly improving inspection efficiency, and is particularly suitable for scenarios like energy storage power stations that require high-frequency, long-cycle inspections. Furthermore, the elimination of manual intervention in the charging process reduces labor costs and avoids blind spots caused by charging interruptions, ensuring real-time monitoring of critical areas of the power station.

[0019] Secondly, the structural design of this solution is stable and reliable, ensuring operational accuracy. Specifically, the inspection track wing plate is equipped with guide grooves, and the guide wheels at the bottom of the inspection trolley are embedded in these grooves, forming a rigid guiding structure that effectively limits the trolley's lateral deviation, ensuring precise operation along the track and preventing inspection path deviations or blurred image acquisition caused by shaking. Furthermore, the brush arm is connected via a pressure spring; the spring's elastic pressure ensures stable contact between the brush and the conductive strip, reducing contact problems even with slight installation errors or vibrations in the track. Simultaneously, the brush arm is hinged via an insulated pivot, adapting to minute positional changes in the conductive strip, further ensuring continuous power supply.

[0020] Third, this solution features comprehensive safety design, adaptable to the unique environment of power stations. It incorporates multiple layers of insulation protection: the conductive strip is secured with insulating clips and covered by a U-shaped insulating protective cover (opening only towards the trolley to prevent external contact) to prevent accidental contact with conductive components by personnel or other equipment; the inspection track is fixed with insulating brackets, achieving electrical isolation from walls or frames to prevent live wires from being conducted to the building structure; the brush arm is connected to the trolley via an insulating shaft, and the brush wires are directly connected to the junction box, reducing the risk of leakage. Furthermore, the conductive strip is made of copper alloy (good conductivity and oxidation resistance), and the brushes are made of copper-graphite composite material (wear-resistant, stable conductivity, and the graphite component reduces spark generation), both suitable for the high-safety-requirement electrical environment of energy storage power stations.

[0021] Fourth, this solution features a simple structure that is easy to install and maintain. The overall structure revolves around a track and inspection trolley, with few components (the slide rails, conductive strips, guide wheels, and power receiving devices are all modularly designed). Installation is simple, requiring only fixing with insulated brackets, making it suitable for various installation scenarios such as substation walls or frames. No modification to the substation floor is needed (avoiding damage to the floor insulation layer or cable layout), making it suitable for both renovations and new construction projects in existing and new substations. Key components (such as brushes and conductive strips) are easy to replace after wear, requiring no complex disassembly, thus reducing subsequent maintenance costs.

[0022] Fifth, this solution offers targeted and flexible inspection capabilities. Through a dynamic inspection mode using a track and mobile trolley, it moves along a preset path (such as the equipment arrangement direction) to specifically inspect multiple sets of equipment. Furthermore, compared to directly installing cameras in the power distribution room (fixed cameras, to cover the entire area, need to be densely installed on each row of equipment and each height level, which is not only costly but also creates "blind spots" due to equipment obstruction), this solution, due to its mobility and self-configurability, offers a larger, wider, and more dynamic detection angle, fewer blind spots, and better inspection results.

Detailed Implementation

[0028] The following detailed explanation illustrates the specific implementation methods:

[0029] Example 1

[0030] The basic implementation examples are as follows: Figure 1 As shown: The energy storage power station safety inspection system includes an inspection trolley 6 and an inspection track 1.

[0031] The inspection trolley 6 is slidably connected to the inspection track 1; as follows: Figure 2 As shown, the inspection track 1 includes a slide rail 2, and a conductive strip 3 is laid parallel to the inner side of the slide rail 2. A guide groove 5 is provided on the wing plate of the slide rail 2. The conductive strip 3 is locked to the web plate of the slide rail 2 by an insulating buckle 4. The end of the conductive strip 3 is connected to the DC bus of the power station. Preferably, a power switch can also be provided between the conductive strip 3 and the DC bus of the power station.

[0032] Specifically, the inspection track 1 is fixed to the power station wall or frame by an insulating bracket. In practical applications, multiple interconnected sections of the inspection track 1 can be laid according to the specific inspection requirements to form a complete and targeted inspection route. In this embodiment, existing fixed brackets can be used as the insulating brackets.

[0033] The connection between the insulating bracket and the inspection track 1 is also equipped with a rubber shock-absorbing pad, which can absorb the vibration of the power station equipment during operation to a certain extent, reduce the impact on the inspection trolley 6, and especially avoid the vibration from causing blurry image acquisition or loose parts.

[0034] The conductive strip 3 is a copper alloy conductive strip 3. Copper alloys have advantages such as good conductivity, oxidation resistance, and wear resistance, making them suitable for the high safety requirements of the electrical environment of energy storage power stations and helping to reduce the frequency of equipment maintenance.

[0035] The conductive strip 3 is covered with a U-shaped insulating protective cover, the opening of which faces the inspection trolley 6. The U-shaped insulating protective cover not only provides insulation but also protects the conductive strip 3 from environmental factors such as dust and moisture, extending its service life.

[0036] like Figure 3 and Figure 4 As shown, the inspection trolley 6 has guide wheels 7 on its bottom side, and the guide wheels 7 are embedded in the guide groove 5. The inspection trolley 6 is also equipped with a power receiving device, an image acquisition unit 12, a positioning module, a junction box, and a motor. The motor is used to drive the guide wheels 7 to rotate, thereby moving the inspection trolley 6 on the inspection track 1 to achieve mobile inspection. Specifically, there are four guide wheels 7, which are located at the four corners of the bottom of the inspection trolley 6. Two guide wheels 7 are connected by a front wheel axle, and two guide wheels 7 are connected by a rear wheel axle. The front wheel axle of the guide wheels 7 is driven by a motor to rotate. The specific driving method is the same as that of existing electric trolleys, so it will not be described in detail.

[0037] The image acquisition unit 12 is used to acquire inspection information; the power receiving device includes a brush arm 8; one end of the brush arm 8 is provided with a brush 9, and the other end is hinged to the inspection trolley 6 through an insulated rotating shaft 10; the wire of the brush 9 is directly connected to the junction box, and the junction box outputs to the motor, the image acquisition unit 12 and the positioning module.

[0038] Specifically, the brush 9 is a copper-graphite composite brush 9. The copper-graphite composite brush 9 has advantages such as wear resistance and stable conductivity, and the graphite component can reduce the generation of sparks, making it suitable for the electrical environment with high safety requirements of energy storage power stations and helping to reduce the frequency of equipment maintenance.

[0039] The image acquisition unit 12 is mounted on the top of the inspection vehicle 6 via a pan-tilt unit 13, allowing for multi-angle adjustment of the inspection viewing angle to accommodate equipment at different heights and locations (such as battery clusters, busbars, control cabinets, etc.). In this embodiment, the image acquisition unit 12 uses an existing high-definition camera. The pan-tilt unit 13 can be an existing electric pan-tilt unit 13. Preferably, depending on actual inspection needs, other data acquisition modules can be added to the inspection vehicle 6 and connected to a junction box, such as a microphone (for collecting equipment operating sounds) and an infrared temperature probe (for collecting equipment temperature).

[0040] The power receiving device is located at the bottom of the inspection trolley 6; the inspection trolley 6 is also equipped with a pressure spring 11, one end of which is fixedly connected to the bottom surface of the inspection trolley 6, and the other end is fixedly connected to the brush arm 8.

[0041] In practical applications, when the power switch is closed and the DC bus of the power station is confirmed to be in normal power supply state, the conductive strip 3 is in a live state. The brush 9 of the inspection trolley 6 draws power by contacting the conductive strip 3. The current is transmitted to the junction box through the wire of the brush 9 and distributed by the junction box to the motor (driving power) and the image acquisition unit 12, positioning module and other electrical components.

[0042] After the motor starts, it drives the inspection trolley 6 to run along the inspection track 1. During the initial operation, observe whether the trolley moves smoothly along the guide groove 5: the guide wheel 7 is embedded in the guide groove 5, and with the rigid constraint of the track, ensures that the trolley does not deviate; at the same time, observe the contact status between the brush 9 and the conductive strip 3 (no continuous sparks, no abnormal noise) to confirm that the power supply is stable.

[0043] The inspection trolley 6 moves at a constant speed along the inspection track 1 (the speed can be set according to the power station inspection density, such as 0.5-2 km per hour), covering the preset inspection area (the inspection area is controlled by adjusting the laying area of ​​the inspection track 1, such as laying it around the energy storage battery compartment, converter cabinet, fire protection facilities, etc.).

[0044] The image acquisition unit 12 works in real time: the angle can be adjusted by the pan-tilt unit 13 (which can be remotely controlled or rotated according to a preset program, depending on the characteristics of the selected pan-tilt unit 13) to capture information such as the appearance of the equipment (whether there are bulges, leaks, or loose cables) and the status (indicator light color); the positioning module records the position in real time to realize the binding of "image-position" information, which is convenient for the background to locate abnormal points.

[0045] During this process, the brush 9 is in close contact with the conductive strip 3 through the adaptive adjustment of the pressure spring 11 and the insulating shaft 10, ensuring that there is no risk of power failure for components such as the motor and the image acquisition unit 12, and achieving "uninterrupted inspection".

[0046] This embodiment provides a safety inspection system for an energy storage power station. The system has a simple structure, is mobile, requires no manual charging, and has high inspection efficiency.

[0047] Example 2

[0048] The safety inspection system for energy storage power stations has been adjusted as follows based on Implementation Example 1.

[0049] The gimbal 13 is also equipped with a mechanical locking knob for fixing the setting angle of the image acquisition unit 12. The mechanical locking knob can fix the angle, ensuring stable acquisition of specific key areas and preventing angle deviation caused by carriage vibration. In this embodiment, an existing mechanical gimbal 13 with locking bolts can be directly selected.

[0050] The energy storage power station safety inspection system provided in this embodiment is more suitable for inspection scenarios that require monitoring at a fixed angle compared to Embodiment 1.
