Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

A lithium battery 10 warehouse safety monitoring system comprises a placing rack for placing lithium batteries 10. Referring to fig. 1, the rack includes a rack body 1, a plurality of independent placing lattices 2 are arranged in the rack body 1, and a camera 3 is fixedly installed on the outer side of the rack body 1.

Referring to fig. 2, a fireproof heat insulation board 4 is arranged on the inner wall of each placing grid 2, and the fireproof heat insulation board 4 is made of asbestos boards. A temperature sensor 5 and a smoke sensor 6 are also arranged in each placing grid 2, and a fire extinguishing box 7 is arranged at the top in the placing grid 2.

Referring to fig. 3, the inside of the fire extinguishing box 7 is a cavity 8, fire extinguishing dry powder is filled in the cavity 8, a plurality of through holes 9 are formed in the top of the fire extinguishing box 7, the through holes 9 are communicated with the cavity 8, and hot melts are filled in the through holes 9. The hot melt in this example is paraffin. The paraffin is solid at normal temperature, plays a role in plugging the through hole 9 and prevents the extinguishing dry powder in the cavity 8 from scattering.

Referring to fig. 4, the lithium battery 10 warehouse safety monitoring system further comprises an MCU module, the MCU module is connected with a power module, a communication module, a storage module and an alarm, and the temperature sensor 5 and the smoke sensor 6 are connected with a sampling signal input terminal of the MCU. The power module is used for supplying power to each module, and the storage module is used for providing a data storage space. The camera 3 is electrically connected with the MCU module.

The communication module in this embodiment can be one or several of WIFI module, bluetooth module, thing networking card communication module, RJ45 module. And establishing communication connection with the upper computer of the system through a communication module.

The working principle of the system is as follows: the lithium batteries 10 are stacked in the placing grids 2 of the placing rack, and the system runs normally. When the lithium battery 10 in one placing grid 2 is in a smoke or fire condition, the temperature sensor 5 or the smoke sensor 6 sends an electric signal to the MCU module, the MCU module receives the electric signal and then controls the alarm to act to send an alarm signal, so that field workers can be reminded to take emergency measures, and the MCU module controls the camera 3 to shoot field pictures; meanwhile, the MCU module generates alarm information, the alarm information and the shot picture are sent out through the communication module, remote alarm and monitoring are achieved, and the situation that dangerous cases cannot be effectively spread when no person is on duty is avoided.

Because the inner wall of every placing grid 2 has all set up fire prevention heat insulating board 4, even if when lithium cell 10 is on fire and the intensity of a fire has the trend of stretching, this placing grid 2 interior fire prevention heat insulating board 4 can effectively prevent the intensity of a fire to stretch to other placing grids 2 to can the separation heat, prevent that lithium cell 10 is heated spontaneous combustion in other placing grids 2. Appear high temperature or the naked light condition in placing grid 2, the paraffin in the through-hole 9 of box 7 bottoms of putting out a fire is heated and is melted for through-hole 9 is opened, and the dry powder of putting out a fire in the cavity 8 spills out in the through-hole 9, covers on the lithium cell 10 surface that gets on fire, thereby puts out the flame, protects other lithium cell 10.

In order to improve the positioning reliability of the system, the power module in this embodiment adopts a UPS power supply, and when a power failure accident occurs in the warehouse power supply, the UPS power supply can continue to supply power to the system, so that the system can continue to operate.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
