Description

Technical Field

[0001] This utility model relates to the field of power station battery monitoring technology, and more specifically, to an online monitoring device for energy storage power station batteries. Background Technology

[0002] As a key facility for energy storage and regulation, energy storage power stations are becoming increasingly important. These stations primarily consist of numerous battery packs. During charging and discharging, these battery packs may experience overheating, short circuits, and leaks due to internal chemical reactions, external environmental factors (such as temperature and humidity), and aging caused by long-term operation. Therefore, real-time and accurate online monitoring of the battery packs in energy storage power stations, and timely detection and early warning of potential safety risks, are crucial for ensuring the safe operation of energy storage power stations, extending battery life, and improving energy utilization efficiency.

[0003] A search revealed that patent application CN202220583808.7 discloses an online monitoring device for batteries in a large-scale energy storage power station. Its technical solution includes: a shell, a first hydraulic rod, and a partition plate. A connecting plate is welded to the top surface of the inner wall of the shell, a connecting frame is installed at the bottom end of the inner wall of the shell, and a battery body is installed on the top surface of the connecting frame. A fixing rod is welded to the inner wall of the connecting plate, and a lead screw is installed on the inner wall of the connecting plate. A rotating shaft is installed on the bottom surface of the partition plate. The partition plate is slidably sleeved on the fixing rod and threadedly connected to the lead screw. A second fixing frame is welded to the bottom surface of the rotating shaft, and a first fixing frame is welded to the bottom surface of the second fixing frame. A second hydraulic rod is installed on the inner wall of the first fixing frame, and a limit plate is installed on the side surface of the first hydraulic rod. This utility model satisfies battery monitoring requirements and can be quickly adjusted according to the actual monitoring position and height, facilitating later use and operation. However, it still has the following drawbacks:

[0004] (1) In the prior art, the temperature sensor and smoke sensor are moved and adjusted to monitor different batteries. It is not possible to measure the temperature of multiple batteries at the same time. They need to be measured one by one, which results in a time delay and poor monitoring effect.

[0005] (2) The existing monitoring devices are not convenient for monitoring the appearance of the battery. After a long period of use, the battery is prone to bulging. It is inconvenient to monitor whether the battery is bulging, and it is easy to miss the best time to replace or maintain the battery, which poses a safety hazard.

[0006] Therefore, we have made improvements to this and proposed an online monitoring device for batteries in energy storage power stations. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes an online battery monitoring device for an energy storage power station, including a base plate 1. A plate sleeve 2 is fixedly connected to the upper end face of the base plate 1. A connecting plate 4 is detachably connected to the plate sleeve 2 via a bolt assembly 3. A mounting plate 5 is fixedly connected to the top of the connecting plate 4. A fixing plate 6 is fixedly connected to the center of the mounting plate 5. Two slide rails 7 are symmetrically and fixedly connected to the front sidewall of the mounting plate 5. A set of sliding plates 8 are slidably connected to each of the two slide rails 7. A telescopic frame 9 is rotatably connected to the fixing plate 6. The intersection of the telescopic frame 9 is rotatably connected to the sliding plate 8. An adjustment mechanism 10 is provided on the rear side of the mounting plate 5. Smoke sensors 11 are fixedly connected to the front sidewalls of both the fixing plate 6 and the sliding plate 8. The rear ends of both the fixed plate 6 and the sliding plate 8 are fixedly connected to the mounting bracket 12. The mounting bracket 12 is equipped with an infrared temperature sensor 13. The mounting plate 5 is equipped with a monitoring mechanism 14. The plate sleeve 2, bolt assembly 3 and connecting plate 4 facilitate installation and disassembly, and also facilitate the adjustment of the height of the mounting plate 5 from the ground. By moving the bottom sliding plate 8, the telescopic frame 9 is moved, thereby moving all the sliding plates 8, which can adjust the spacing between adjacent smoke sensors 11 and adjacent infrared temperature sensors 13. This makes it easier to adjust the monitoring spacing according to the spacing between batteries, which is more flexible and facilitates the simultaneous monitoring of multiple batteries, improving the monitoring effect and timeliness.

[0031] like Figure 2As shown, in a preferred embodiment, based on the above method, the spacing adjustment mechanism 10 further includes two fixing blocks 1001 fixed on the rear side wall of the mounting plate 5. A first screw 1002 is rotatably connected between the two fixing blocks 1001. A knob 1003 is fixedly connected to the bottom end of the first screw 1002. A movable opening is provided on the mounting plate 5, and a movable frame 1004 is provided in the movable opening. One end of the movable frame 1004 is threadedly connected to the first screw 1002, and the other end of the movable frame 1004 is fixedly connected to the bottom slide plate 8. By rotating the knob 1003, the first screw 1002 is driven to rotate, which drives the movable frame 1004 to move in the movable opening, so that the slide plate 8 slides on the slide rail 7, thereby causing the telescopic frame 9 to move, driving all the slide plates 8 to slide, and thus adjusting the spacing, which facilitates the monitoring of multiple batteries.

[0032] like Figure 1 , Figure 4 and Figure 6 As shown, in a preferred embodiment, based on the above method, the monitoring mechanism 14 further includes a mounting frame 1401 fixed on the mounting plate 5. A second screw 1402 is rotatably connected inside the mounting frame 1401. A motor 1403 is fixedly connected to the upper end face of the mounting frame 1401. The driving end of the motor 1403 passes through the top wall of the mounting frame 1401 and is fixedly connected to the top end of the second screw 1402. A height adjustment block 1404 is threadedly connected to the second screw 1402. A mounting plate 1405 is fixedly connected to the end of the height adjustment block 1404. A camera 1406 is mounted on the mounting plate 1405. By driving the second screw 1402 to rotate through the motor 1403, the height adjustment block 1404 moves up and down, realizing flexible adjustment of the height of the camera 1406. The camera 1406 can capture monitoring images at different heights and can transmit the monitoring images to the terminal, so that external personnel can understand the situation of battery bulging in a timely manner.

[0033] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the rear side wall of the mounting plate 5 is further equipped with an audible and visual alarm 15, a wireless transmission module 16, and a controller 17, which are installed sequentially from top to bottom. The smoke sensor 11, infrared temperature sensor 13, audible and visual alarm 15, and wireless transmission module 16 are electrically connected to the controller 17. This enables real-time monitoring of the smoke and temperature of the battery pack in the energy storage power station. Once an abnormality is detected, the signal will be transmitted to the controller 17. The controller 17 will then control the audible and visual alarm 15 to issue an alarm signal based on the received signal, promptly reminding staff to handle the abnormality. At the same time, the wireless transmission module 16 will send the alarm information to the remote monitoring center, realizing remote monitoring and timely response, and improving the safety and reliability of the energy storage power station.

[0034] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, the bolt assembly 3 further comprises a bolt and a nut, and a set of insertion holes that match the bolts in the bolt assembly 3 are evenly provided on the connecting plate 4; this facilitates adjustment of the extension length of the connecting plate 4, thereby facilitating adjustment of the ground clearance of the bottom end of the mounting plate 5, and allowing for flexible adjustment according to actual usage.

[0035] like Figure 1 As shown, in a preferred embodiment, based on the above method, the fixing plate 6 and the sliding plate 8 are of the same size, and mounting holes are provided at the four corners of the base plate 1; the mounting holes facilitate the fixing of the base plate 1 with fixing bolts, etc., thereby improving the stability during monitoring.

[0036] Specifically, when using the online battery monitoring device of this energy storage power station: the base plate 1 is fixed at the monitoring position, then the bolt assembly 3 is disassembled, the mounting plate 5 is moved to the target height, and then the plate sleeve 2 and the connecting plate 4 are fixed by the bolt assembly 3. Then, the knob 1003 is rotated to drive the first screw 1002 to rotate, which drives the moving frame 1004 to move within the moving opening, so that the slide plate 8 slides on the slide rail 7, thereby causing the telescopic frame 9 to move, driving all the slide plates 8 to slide, thereby adjusting the position of the smoke sensor 11 and the infrared temperature sensor 13, so that each set of smoke sensor 11 and infrared temperature sensor 13 corresponds to one battery, thereby enabling corresponding battery monitoring. The motor 1403 drives the second screw 1402 to rotate. The camera 1406 is moved up and down by the height adjustment block 1404, allowing for flexible adjustment of its height. The camera 1406 can capture monitoring images at different heights, facilitating the monitoring of the entire battery's appearance. If a battery is found to be bulging, it can be replaced promptly. The smoke sensor 11 and infrared temperature sensor 13 can monitor the smoke and temperature of the battery pack in the energy storage power station in real time. Once an abnormality is detected, the signal will be transmitted to the controller 17. The controller 17 will then control the audible and visual alarm 15 to issue an alarm signal, promptly reminding staff to handle the abnormality. At the same time, the wireless transmission module 16 will send the alarm information to the remote monitoring center, realizing remote monitoring and timely response, and improving the safety and reliability of the energy storage power station.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
