Description

Technical Field

[0001] The utility model relates to the technical field of fireproof energy storage equipment, and in particular to a fireproof early warning type electrochemical energy storage device. Background Art

[0002] Electrochemical energy storage devices have certain safety hazards during use, mainly including overcharging, over-discharging, short circuit and other problems. Overcharging will cause gas to be generated inside the battery, increasing the internal pressure of the battery, thus causing explosion or fire; while short circuit will cause excessive current inside the battery, generating high temperature, and also cause fire hazards. Once these safety hazards occur, they will not only damage the electrochemical energy storage device itself, but also cause serious harm to the surrounding environment and personnel.

[0003] Existing fire protection devices usually install sprinklers on the top of the machine room to cool down by spraying water. However, sprinklers installed on the top of the machine room are prone to lag. Usually, sprinklers will spray water to extinguish the fire only after the fire has started. In addition, the spraying range is large, and the efficiency is low during the fire extinguishing process. This requires a device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a fire-prevention early warning electrochemical energy storage device, comprising a shell 1, a spraying mechanism and a blocking mechanism, the two sides of the shell 1 are fixedly connected with a support seat 2 by bolts, and an air inlet 7 is opened on one side of the shell 1;

[0023] The spraying mechanism includes a spray head 3, a water pump 4 and a sealing block 5. A water tank 6 is provided inside the support base 2. The water pump 4 is provided inside the water tank 6. The spray head 3 is provided on the side of the support base 2 facing the housing 1. The sealing block 5 is provided on the surface of the spray head 3. The sealing block 5 is used to seal the spray head 3.

[0024] The blocking mechanism includes a roller 8 and a rolling curtain 9. A ventilation compartment 10 and an equipment compartment 11 are provided inside the shell 1. The roller 8 is arranged on the inner wall of the ventilation compartment 10. The rolling curtain 9 is wound on the outer surface of the roller 8. The rolling curtain 9 is used to close the air inlet 7. A partition mechanism is provided inside the equipment compartment 11. A pressure sensor is provided on one side of the partition mechanism. The partition mechanism is used to press against the pressure sensor after thermal expansion.

[0025] The support seat 2 is fixed on both sides of the shell 1 to support the shell 1 and lift the shell 1 off the ground to reduce contact with the ground. The battery cell is installed in the equipment compartment 11. The ventilation compartment 10 is used to cool the equipment compartment 11. At the same time, the air inlet 7 allows cold air from the outside to enter. When an abnormal condition occurs inside the equipment compartment 11 and the temperature rises, the partition mechanism expands due to heat, triggering the pressure sensor on the opposite side, transmitting the abnormal signal, and allowing the operator to come and check. At the same time, the roller 8 starts to lower the roller curtain 9, and the roller curtain 9 closes the air inlet 7 to block the outside air from entering the equipment compartment 11 and reduce the risk of fire. When a fire occurs outside, the sealing block 5 is made of hot-melt material, and the external flame will burn the sealing block 5 to expose the internal nozzle 3. At the same time, the water pump 4 starts to spray the water in the water tank 6 on the shell 1 to cool the shell 1. The sealing block 5 is used to protect the nozzle 3 and reduce the situation where the nozzle 3 is blocked and cannot be sprayed.

[0026] In this embodiment, as a preferred solution, a blocking plate 12 is provided on the outer surface of the shell 1 through a snap-fit ​​mechanism. The blocking plate 12 is used to block high temperature. The snap-fit ​​mechanism includes a slot 13 opened on the surface of the shell 1 and a buckle 14 fixedly connected to the lower surface of the blocking plate 12. The buckle 14 and the slot 13 are snap-fitted.

[0027] The baffle plate 12 is made of flame-retardant material and is arranged on the outside of the shell 1. It can protect the internal shell 1 when a fire occurs. At the same time, the baffle plate 12 is designed for quick release. After the fire is over, if the shell 1 is not damaged, the baffle plate 12 can be removed and only the baffle plate 12 needs to be replaced, thereby reducing the subsequent maintenance cost.

[0028] In this embodiment, as a preferred solution, a through hole 15 is opened on one side of the equipment bin 11, and the equipment bin 11 is communicated with the ventilation bin 10 through the through hole 15. The partition mechanism includes a baffle 16 and an expansion portion 17. The baffle 16 is arranged on the inner wall of the equipment bin 11, and one end of the baffle 16 can be pressed against the inner wall of the ventilation bin 10. The expansion portion 17 is arranged at the other end of the baffle 16. The expansion portion 17 is used to push the baffle 16 to move to one side, and the end of the expansion portion 17 away from the baffle 16 is fixedly connected to the inner wall of the equipment bin 11.

[0029] Outside air enters the ventilation chamber 10 from the air inlet 7, and then enters the equipment chamber 11 from the ventilation chamber 10 to cool the equipment. The expansion portion 17 can be expanded perlite, which will expand after being heated, thereby pushing the baffle 16 to one side so that the baffle 16 touches the pressure sensor. One end of the expansion portion 17 is fixed to prevent the baffle 16 from accidentally touching the pressure sensor when the shell 1 shakes. After the baffle 16 is pressed against the pressure sensor, the baffle 16 can separate the equipment chamber 11 into two areas, reducing the impact on the other area when one of them catches fire.

[0030] In this embodiment, as a preferred solution, a water inlet 18 and a hook 19 are provided on the top of the support seat 2 , and the water inlet 18 is communicated with the interior of the water tank 6 .

[0031] The water injection port 18 is used to add fire extinguishing agent into the water tank 6. The water tank 6 is used to adjust the position of the device. At a non-movable device, the water injection port 18 can be connected to the water inlet pipe, and the fire extinguishing agent is directly transported to the nozzle 3 by the water inlet pipe, thereby providing a longer spraying time, which can be adjusted according to different situations. A water level gauge is provided on the side of the water tank 6, which can easily check the content in the water tank 6 for timely refilling.

[0032] In the utility model, the working steps of the device are as follows:

[0033] 1. When in use, install the support base 2 on both sides of the housing 1 and move the device to the desired position;

[0034] 2. According to different usage conditions, selectively add fire extinguishing agent into the water tank 6 or connect the water inlet pipe to the nozzle 3 for use;

[0035] 3. After the connection is completed, the baffle plate 12 can be installed on the outer surface of the shell 1.
