[0046] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0047] How to detect the response performance of the energy storage power station fire prevention early warning system is a difficult problem in the field. In order to test the detection performance of the detection device, the simulated battery fire condition will be directly used to test the detection device, and whether the detection device can timely output alarm information or fire extinguishing instruction is observed. When it is found that the instruction can be correctly output, it is judged that the early warning system is qualified, otherwise it is unqualified. However, in the actual battery fire process, the gas and smoke generated by the battery combustion are mixed together, and the existing device for simulating battery thermal runaway will discharge the gas and smoke separately for the detection device to detect, which will affect the accuracy of detection.

[0048] To solve the above technical problems, in at least one embodiment, an auxiliary device for simulating energy storage power station fire prevention is provided, comprising: a heating bin 1, a heating mechanism 4 is arranged inside the heating bin 1; at least two gas tanks 2 are arranged inside the heating bin 1; a mixed gas bin 21 and a smoke generator 3 are arranged inside the heating bin 1; and a discharge mechanism 5 is arranged on the heating mechanism 4 and connected with the mixed gas bin 21 and the smoke generator 3 respectively; wherein when the heating mechanism 4 heats the inside of the heating bin 1 to a set value, the discharge mechanism 5 is adapted to discharge the gas in the mixed gas bin 21 and the smoke in the smoke generator 3 together to the outside of the heating bin 1, thereby simulating the fire of the energy storage power station;

[0049] By arranging the heating mechanism, the inside temperature of the heating bin can be quickly heated to the set value, the structure is simple, the heating efficiency is high, and the discharge mechanism is used synchronously to mix and discharge the gas and smoke, so as to truly simulate the mixed smoke generated when the battery thermal runaway occurs, thereby improving the detection accuracy of the detection device.

[0050] In some embodiments, as Figure 1As shown, at least two gas tanks 2 and a smoke generator 3 are placed inside the heating chamber 1, and the two gas tanks 2 are connected to the mixed gas chamber 21 by a tee. The gases in the two gas tanks 2 are preferably hydrogen and carbon monoxide. When the battery fire simulation starts, the gases in the two gas tanks 2 are introduced into the mixed gas chamber 21 through the tee for mixing, and then the mixed gas is introduced to the outside of the heating chamber 1 through the exhaust pipe 22, and the smoke generator 3 is started synchronously to discharge the smoke generated by it to the outside of the heating chamber 1 through the exhaust pipe 3. The detection device is placed outside the heating chamber 1 to detect the discharged mixed gas and smoke, and the display of the detection device is observed.

[0051] In some embodiments, as Figure 2 As shown, at the beginning of the simulation experiment, the motor 40 is started, and its output end drives the turntable 400 to rotate. At the same time, the plurality of magnetic blocks 41 fixed on the turntable 400 rotate, bending a portion of the copper tube into a ring shape and fixing it above the turntable 400. Since the upper end surfaces of each two adjacent magnetic blocks 41 have opposite magnetic poles, when the plurality of magnetic blocks 41 rotate, a rapidly alternating magnetic field is generated, which generates eddy currents near the copper tube, causing the copper tube to heat up, thereby increasing the internal temperature of the heating chamber 1 until it reaches the set value;

[0052] Depend on Figure 2 As can be seen, the copper tube 42 is filled with liquid, preferably water. As the motor 40 is started, the pump 44 is started synchronously to circulate the water in the copper tube 42, and the remaining part of the copper tube is bent to fit the inner wall of the heating chamber 1, so as to improve the efficiency of increasing the temperature inside the heating chamber 1.

[0053] Before starting the simulation experiment, open the water valve 432, start the pump 44, and pump water from the water tank 43 into the copper pipe 42 through the water pipe 431 for use in subsequent simulation experiments.

[0054] In some embodiments, as Figure 2 As shown, when the motor 40 drives the turntable 400 to rotate, it drives the rotating shaft 51 to rotate, and then drives the driving gear 52 to rotate. Since the driving gear 52 is engaged with the driven gear 54, the rotating rod 53 fixed to the driving gear 54 is driven to rotate around the bearing connection between it and the discharge bin 50, and then drives the fan blades 55 on the rotating rod 53 to rotate, so as to discharge the gas entering the discharge bin 50 through the exhaust pipe 22 and the smoke exhaust pipe 30 together with the smoke to the outlet port of the discharge bin 50, so as to improve the authenticity of the scene of the mixed smoke generated by the thermal runaway of the battery in real life, and thereby improve the accuracy of the test results of the detection device.

[0055] In conclusion, by setting the heating mechanism, the internal temperature of the heating bin can be quickly heated to the set value, the structure is simple, the heating efficiency is high, and the discharge mechanism is used synchronously, the gas is mixed and discharged with the flue gas, the mixed flue gas generated when the battery thermal runaway is truly simulated, and the detection accuracy of the detection device is improved.
