[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0022] The utility model provides a technical solution: Figures 1 to 4 As shown, in this embodiment, a battery safety monitoring device includes a monitoring frame 1, wherein support plates 2 are fixedly installed inside the monitoring frame 1, and the support plates 2 are evenly distributed. A battery body 3 is provided on the top of each support plate 2, and a terminal 17 is installed on the top of each battery body 3. A monitoring component is provided on one side of each battery body 3;

[0023] Among them, the monitoring component includes a monitor 7 arranged on one side of the battery body 3, the top of the monitor 7 is connected to the pole 17 through a connecting line 18, a mounting plate 6 is installed on one side of the monitor 7, and a connecting seat 5 is provided below both ends of the mounting plate 6. A connecting component is provided between the mounting plate 6 and the connecting seat 5, and the connecting seat 5 is fixedly installed on the end of the fixing frame 4, and the fixing frame 4 is fixedly installed on the top of the support plate 2.

[0024] The monitor 7 is specifically a single-module early warning instrument, model: DLT_B, which adopts a "modular" structure;

[0025] It includes sensor module, convergence module, wireless module and display and control module. The sensor module is used to test battery voltage, internal resistance and temperature parameters and send data through D-BUS bus.

[0026] The aggregation module is used to realize the level conversion from D-BUS bus to RS485 interface and collect current at the same time;

[0027] The wireless module is used to realize wireless transmission and reception of data;

[0028] The display and control module is used to collect, display and upload battery data;

[0029] A sensor module is installed on each battery to collect the voltage, temperature and internal resistance information of the single battery;

[0030] Each battery pack is equipped with a convergence module to collect battery pack current and sensor module data;

[0031] Each sensor module is connected to the aggregation module through an internal bus;

[0032] By configuring the monitoring components, during the operation of the battery, the monitor 7 monitors the battery body 3 in real time, including comprehensive parameter indicators in the charging, discharging, floating charge, and floating states. Online fault diagnosis and timely data upload reduce manual maintenance costs. The terminal voltage values ​​of all cells in the entire group can be controlled to remain basically consistent, with the difference meeting the requirements of YD / T1970.10. Online balancing and control are performed on each cell in the battery pack to keep the terminal voltage of each cell at a balanced value, preventing over- or undercharging of the cells and deterioration of the batteries due to long-term floating charge. This maintains a high degree of consistency in the battery pack, greatly improving the safety, reliability, and service life of the battery equipment. The "modular" structure avoids the current monitoring methods that generally require portable internal resistance meter measurement, battery inspection instruments, periodic capacitive discharge, "one-size-fits-all" replacement of the entire group, and manual inspections. During use, such monitoring methods not only have low monitoring accuracy and limited scope (i.e., they can only simply monitor the battery voltage status), but also require manual data collection and inspection management, resulting in poor battery monitoring results.

[0033] like Figures 1 to 4 As shown, the connecting assembly includes a connecting block 11 installed inside the connecting seat 5, the top of the connecting block 11 is embedded in the connecting groove 20, the connecting groove 20 is opened inside the mounting plate 6, and the bottom end of the connecting block 11 is provided with a spring 14, which is installed inside the connecting seat 5.

[0034] Through the setting of the connecting assembly, when the monitor 7 is installed on the side wall of the battery body 3, the mounting plate 6 is first placed on the top of the connecting seat 5, and the connecting block 11 is embedded in the inside of the connecting groove 20 to connect the connecting seat 5 and the mounting plate 6 to ensure the stability of the monitor 7 when in use.

[0035] like Figures 1 to 4 As shown, a slider 12 is fixedly mounted on one side of the connecting block 11 , the slider 12 is slidably mounted inside the connecting seat 5 , and a connecting rod 13 is provided above the slider 12 .

[0036] When a battery body 3 needs to be removed for maintenance, the connecting rod 13 is first pressed downward. The movement of the connecting rod 13 drives the movement of the slider 12, and the movement of the slider 12 drives the movement of the connecting block 11, so that the connecting block 11 slides out of the interior of the connecting groove 20, and the connecting seat 5 is separated from the mounting plate 6, making it easier to remove a battery body 3 for maintenance.

[0037] like Figures 1 to 4 As shown, an insert rod 15 is fixedly mounted on the end of the connecting rod 13 , and the insert rod 15 is embedded in a slot 16 , which is opened at the top of the connecting seat 5 .

[0038] The insertion rod 15 is elastically configured, such as rubber. Rubber has excellent elasticity and flexibility, can be deformed under the action of external force, and quickly returns to its original shape after the external force is removed;

[0039] When a battery body 3 needs to be removed for maintenance, the downward movement of the connecting rod 13 drives the movement of the insertion rod 15, so that the insertion rod 15 is embedded in the inside of the slot 16. The insertion rod 15 is clamped through the slot 16 to fix the position of the connecting rod 13, so that the connecting block 11 remains inside the connecting seat 5 for easy maintenance.

[0040] like Figures 1 to 4 As shown, a support plate 8 is provided at the bottom end of the battery body 3 , and the support plate 8 is slidably mounted on the top end of the support plate 2 .

[0041] Each battery body 3 is individually carried by the supporting plate 8, which makes it easy to take out a certain battery body 3 separately, thereby improving the convenience during manual maintenance.

[0042] like Figures 1 to 4 As shown, a handle 9 is fixedly connected to the side wall of the support plate 8.

[0043] Through the handle 9, the staff can pull the handle 9 on both sides of the battery body 3 to pull out the support plate 8 carrying the battery body 3, further improving the convenience of manual maintenance.

[0044] like Figures 1 to 4 As shown, exhaust fans 10 are installed on the side walls of the monitoring frame 1, and the exhaust fans 10 are evenly arranged.

[0045] The exhaust fan 10 is driven by a motor to rotate the blades, which is a common technical means and will not be described in detail here;

[0046] The exhaust fan 10 is used to control the temperature of the battery body 3 during use, so as to keep the battery within a suitable operating temperature range, which helps to improve its performance stability.

[0047] The utility model provides a battery safety monitoring device, the specific working principle of which is as follows:

[0048] When performing safety monitoring on the battery, first place the battery body 3 on the top of the support plate 8, then place the support plate 8 on the top of the support plate 2, and arrange several battery bodies 3 in order;

[0049] Then place the mounting plate 6 on top of the connecting seat 5 so that the connecting block 11 is embedded in the connecting groove 20, and install the mounting plate 6 on the top of the connecting seat 5;

[0050] Finally, the monitor 7 is connected to the pole 17 of the battery body 3 through the connecting line 18 to perform safety monitoring.

[0051] When a battery body 3 needs to be removed for maintenance, first remove the connecting line 18 between the monitor 7 and the battery body 3, then press the connecting rod 13 downward to make the insertion rod 15 embedded in the inside of the slot 16 and fixed. The movement of the connecting rod 13 drives the slider 12 to move downward, and the movement of the slider 12 drives the connecting block 11 to slide out of the inside of the connecting groove 20, then remove the mounting plate 6 from the top of the connecting seat 5, pull the handle 9 to drive the support plate 8 to carry the battery body 3 out.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
