Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a flange quick-insertion type temperature-sensitive release component. Background Art

[0002] In recent years, as lithium batteries have many advantages such as high energy density, high output power, and long charge and discharge life, they have been widely used in the fields of transportation power, power storage, and mobile communications, and have developed into a part of my country's strategic emerging energy industry. With the official promulgation and implementation of the "Safety Regulations for Electrochemical Energy Storage Power Stations" on July 1, 2023, the standard clearly stipulates that lithium battery energy storage fire protection must protect the battery module and have multiple spray start functions. At the same time, it should have an automatic start function and a mechanical emergency start function.

[0003] In response to the module-level fire protection design requirements, the traditional approach is to place a sprinkler on the module panel and control the spraying and stopping of the nozzle through an external control valve. This method has a fast response speed and can spray and stop immediately, but there is also a risk of accidental spraying.

[0004] The utility model patent with application number CN201721320598.8 discloses a liquid-filled fire-fighting battery module storage and charging and discharging box system. When a fire occurs in a warehouse, the composite sensor transmits the detected smoke and fire signal to the control module. The control module controls the disconnection of the circuit and the connection of the pipeline through a controllable on-off switch and a control valve, and fills the liquid storage box in the box with water until the battery is completely submerged, thereby carrying out a thorough firefighting without affecting other warehouses.

[0005] The utility model patent with application number CN202321856675.7 discloses a battery box fire extinguishing system based on liquid nitrogen and carbon dioxide. Liquid nitrogen and carbon dioxide are used as fire extinguishing agents. When the battery loses control and an initial fire occurs, the fire extinguishing agent is quickly sprayed through precise one-to-one control of the fire sprinklers.

[0006] However, the fire-fighting equipment of the above two patents has a relatively limited protection scope, a complex structure, and no function to prevent accidental spraying. Utility Model Content

[0010] Preferably, a first sealing groove is provided in the flange, a first sealing ring for sealing the fire detection tube is installed in the first sealing groove, and an annular groove is provided on the first sealing ring.

[0017] Preferably, a joint portion is provided on the flange, and a thread connected to the fire extinguishing agent bottle is provided on the joint portion.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-6 The utility model is further described in detail with examples.

[0027] Example 1

[0028] A flange quick-plug temperature-sensing release component includes a fire detection tube 8 and a claw 3. In this embodiment, when there is high temperature somewhere in the module, the fire detection tube 8 will have a breach at that point, and the fire extinguishing agent will spray into the battery from the breach. The claw 3 is used to clamp the fire detection tube 8, and also includes a flange 2 fixed on the panel 1, a cavity 201 is provided in the flange 2, and the claw 3 is installed in the cavity 201. The end of the fire detection tube 8 passes through the claw 3 and is connected to the flange 2. In this embodiment, the end of the flange 2 is an interface for an external fire extinguisher, and the interface is connected to the fire detection tube 8.

An annular groove 401 is provided on the first sealing ring 4. In this embodiment, the first sealing ring 4 is a Y-shaped sealing ring. When the temperature-sensing fire detection tube 8 is inserted, the Y-shaped surface of the Y-shaped sealing ring can be squeezed to be smoothly inserted. If gas is input from the outside of the flange 2, the Y-shaped single side surface opens, which is beneficial to the sealing of the fire detection tube 8.

[0030] There are 6 strip grooves 301 on the claw 3. In this embodiment, the strip grooves 301 are convenient for squeezing the claw 3 to be installed inside the flange 2. An oblique opening 302 is provided on the inner side of the end of the claw 3. The oblique opening 302 and the inner surface of the claw 3 form a barb 304 for clamping the fire detection tube 8.

[0031] A boss 303 is provided on the outer peripheral side of the clamping claw 3, a step 202 matching with the boss 303 is provided in the flange 2, and a convex portion 203 contacting with the oblique opening 302 is also provided in the flange 2. In this embodiment, when the temperature-sensing fire detection tube 8 passes through the inside of the clamping claw 3, the clamping claw 3 is expanded outward under the action of the step 202 inside the flange 2, and the fire detection tube 8 can smoothly pass through the clamping claw 3 and form a seal with the first sealing ring 4. At the same time, the oblique opening 302 inside the clamping claw 3 forms a clamping barb 304 with the temperature-sensing fire detection tube 8 to prevent it from being disengaged. When the temperature-sensing fire detection tube 8 needs to be disassembled, it is only necessary to press the clamping claw 3, and the clamping claw 3 is expanded under the action of the convex portion 203 inside the flange 2, so as to contact the barb 304 and fix the temperature-sensing fire detection tube 8.

In this embodiment, the temperature-sensing fire detection tube 8 can be bent and arranged according to the battery cells in the battery module, and the end is provided with a hose plug 9 fixed to the temperature-sensing fire detection tube 8 by interference fit.

[0034] The end of the fire detection tube 8 is provided with an insulating protective sleeve 10 for wrapping the hose plug 9. It is used for insulating protection of the fire detection tube 8.

[0035] The flange 2 is provided with a joint portion 207 , and the joint portion 207 is provided with a thread 2071 connected to the fire extinguishing agent bottle.

[0036] Working principle: the flange 2 is fixed on the panel 1 of the battery module, and the claws 3 and the sealing ring are installed in the flange 2. When the temperature-sensing fire detection tube 8 passes through the inside of the claw 3, the claw 3 is expanded outward under the action of the step 202 inside the flange 2, and the fire detection tube 8 can smoothly pass through the claw 3 and form a seal with the first sealing ring 4. At the same time, the oblique mouth 302 inside the claw 3 forms a clamping barb 304 with the temperature-sensing fire detection tube 8 to prevent it from being disengaged. When the temperature-sensing fire detection tube 8 needs to be disassembled, it is only necessary to press the claw 3, and the claw 3 is expanded under the action of the convex part 203 inside the flange 2, so as to contact the barb 304 and fix the temperature-sensing fire detection tube 8; the temperature-sensing fire detection tube 8 can be bent and arranged according to the battery cells in the battery module. When there is high temperature somewhere in the module, the fire detection tube 8 will have a breach at that point, and the fire extinguishing agent will be sprayed into the battery from the breach.
