Description

A multi-path fire extinguishing and protection device Technical Field

[0001] This utility model relates to the field of battery protection technology, specifically to a multi-channel fire extinguishing and protection device. Background Technology

[0002] In the current conventional field of electrochemical energy storage fire protection, the fire extinguishing and protection device corresponding to a prefabricated energy storage compartment is usually divided into a fire extinguishing and protection zone according to the battery compartment structure layout. The fire extinguishing and protection device is then divided into a certain number of fire extinguishing and protection zones. After the fire extinguishing agent is released from the agent bottle, it enters the main pipeline. According to the fire alarm linkage control strategy of the fire protection system, the fire extinguishing agent is delivered to the specific protection zone according to the preset strategy by opening and closing the control valve of the control zone. In existing prefabricated electrochemical energy storage compartments, the fire protection devices corresponding to the battery pack modules in the battery compartment are typically divided into 6 module-level fire protection zones and one independent compartment-level protection zone, for a total of 7 protection zones. The main pipeline needs to extend to the top of each zone, and each zone control valve also needs to be equipped with a control module to receive signals from the fire alarm control host. Each zone control valve and control module needs to be equipped with power supply and communication harnesses, and the pipelines and cables need to be connected to the top of each protection zone. Common zone control valves include solenoid valves and electric ball valves, which require continuous DC 24V power supply when open, and the operating power is about 20-50W. An energy storage system needs to be equipped with 7 zone control valves, and the system backup power needs to be increased by 140-350W. Therefore, the existing fire protection device has a relatively complex structure and consumes a lot of power. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0025] Please refer to Figures 1-6. An embodiment of this utility model provides a multi-channel fire extinguishing and protection device, comprising a valve body 1, a receiving cavity 11 disposed inside the valve body 1 for containing fire extinguishing agent, an inlet penetrating a first side of the valve body 1, a first mounting through hole penetrating a second side of the valve body 1, an outlet 12 penetrating a third side of the valve body 1, a piercing drive 4 connected at one end to the first mounting through hole, an inlet seal 2 detachably installed at the inlet, and an outlet seal 3 installed at the outlet 12. The inlet, the first mounting through hole, and the outlet 12 are respectively connected to the receiving cavity 11. There are multiple outlets 12, multiple first mounting through holes corresponding to multiple outlets 12, multiple outlet seals corresponding to multiple outlets 12, and multiple piercing drive 4 corresponding to multiple first mounting through holes. The piercing drive 4 can pierce the corresponding outlet seal 3, allowing the fire extinguishing agent in the receiving cavity 11 to pass through the outlet seal 3 and flow out of the valve body 1.

[0026] Here, the outlet seal 3 is installed at the outlet 12 to seal the outlet 12. One end of the puncture drive 4 is connected to the first mounting through hole to seal the first mounting through hole. When the inlet seal 2 is not installed at the inlet, fire extinguishing agent is injected into the receiving cavity 11 from the inlet. After injection, the inlet seal 2 is installed at the inlet to seal the inlet. When it is necessary for fire extinguishing agent to flow out from one or more outlets 12, the puncture drive 4 punctures the corresponding outlet seal 3, allowing the fire extinguishing agent in the receiving cavity 11 to pass through the outlet seal 3 and flow out of the valve body 1. The structure is simple and the operation is convenient.

[0027] Specifically, given the current cost-constrained environment in the electrochemical energy storage field, this application proposes a multi-path fire suppression and protection device. Each energy storage system's subsystem design and component selection must be rigorously considered in terms of design cost and spatial layout. Therefore, this application proposes a multi-path fire suppression and protection device that replaces the independent zone control valve with 1-2 multi-path fire suppression and protection devices per energy storage system. For a medium-sized energy storage power station, this is expected to reduce costs by tens of thousands of yuan. In addition, the additional backup power design cost required for the energy storage system when using electric zone control valves must also be considered.

[0028] Multiple outlets 12 can be set at equal intervals, and multiple first mounting through holes can be set at equal intervals.

[0029] Specifically, there can be 5 outlets 12, 5 first mounting through holes, 5 outlet seals 3, and 5 puncture actuators 4. The valve body 1 is equipped with 1 inlet and 5 outlets 12. Depending on the application scenario and linkage control strategy, one or more puncture actuators 4 can be activated to form one or more passages within the receiving cavity 11. The fire extinguishing agent to be delivered is then delivered to a specific pipeline section through the puncture actuators 4 and the corresponding outlet seals 3 according to the preset control strategy.

[0030] The axis of the first mounting through hole can coincide with the axis of the outlet 12 corresponding to the first mounting through hole, the axis of the receiving cavity 11 coincides with the axis of the valve body 1, and the axis of the outlet 12 is perpendicular to the axis of the receiving cavity 11.

[0031] Specifically, the valve body 1 can be a rectangular body, the receiving cavity 11 can be a rectangular body, the first side of the valve body 1 is connected to the second side and the third side of the valve body 1 respectively, and the second side of the valve body 1 is parallel to the third side of the valve body 1.

[0032] The outlet seal 3 may include a sealing diaphragm 32 and an outlet fixing structure; the outlet fixing structure is connected to the side wall of the sealing diaphragm 32 and the outlet 12 respectively, so that the sealing diaphragm 32 seals the outlet 12.

[0033] The puncture drive 4 may include a drive housing 41, a pin 42, and a drive structure disposed inside the drive housing 41. One end of the drive housing 41 is inserted into the first mounting through hole. The drive structure can push the pin 42 to move toward the sealing diaphragm 32 corresponding to the puncture drive 4, so that the pin 42 punctures the sealing diaphragm 32.

[0034] Specifically, a valve body 1 should be designed with 5-8 outlets 12 and one inlet; the center of the ejector pin 42 of the piercing drive 4 should be aligned with the center of the sealing diaphragm 32 to ensure that the ejector pin 42 pierces the sealing diaphragm 32 when the drive structure is in operation.

[0035] The outlet fixing structure may include a quick-connect plug 31, a clamping nut 33, and a first connecting through hole disposed inside the quick-connect plug 31. The quick-connect plug 31 includes a first mounting part disposed inside the plug, and a sealing diaphragm 32 abuts against the first mounting part. The clamping nut 33 is connected to the inner wall of the quick-connect plug 31 to fix the sealing diaphragm 32 inside the quick-connect plug 31. The quick-connect plug 31 is inserted into the outlet 12.

[0036] The outlet fixing structure may also include two sealing washers 34, both of which are disposed inside the quick connector 31. The first side of the first sealing washer 34 abuts against the first mounting part, and the two sides of the sealing diaphragm 32 abut against the first side of the first sealing washer 34 and the first side of the second sealing washer 34, respectively. The clamping nut 33 is connected to the inside of the quick connector 31 and abuts against the second side of the second sealing washer 34.

[0037] Specifically, the sealing diaphragm 32 is fixed and pressed by one clamping nut 33 and two sealing washers 34 to ensure that the sealing diaphragm 32 forms a physical isolation between the inside and outside before it is punctured.

[0038] The drive structure can be an electric explosion valve 43, and the puncture drive component 4 also includes a connector 44 disposed at the other end of the drive housing 41; one end of the connector 44 is connected to the electric explosion valve 43, and the other end can be connected to external electrical equipment; the electric explosion valve 43 contains an initiating agent that can be detonated by electric current.

[0039] Specifically, the ejector pin 42 is connected to the electric detonation valve 43. The electric detonation valve 43 contains an initiating agent, which can be detonated by a small current with a fast response. After the initiating agent undergoes a chemical reaction, a certain amount of high-pressure gas is generated inside the electric detonation valve 43. The gas expands and pushes the ejector pin 42 towards the sealing diaphragm 32. After the ejector pin 42 moves a certain distance, it comes into contact with the sealing diaphragm 32. If the ejector pin 42 continues to move, it can pierce the sealing diaphragm 32.

[0040] Specifically, connector 44 can be connected to the electric explosion valve 43 via a wire. Connector 44 can be a 2-pin connector 44, which facilitates mating and wiring, improving production efficiency. The connector 44 in this application can be the electrical connector disclosed in CN116176898A, a compressed gas ejection mechanism for an electrically fired UAV.

[0041] Specifically, the driving structure in this application can adopt the gas-driven valve disclosed in CN212235742U, a perfluorohexanone fire extinguisher cabinet, and the ejector pin 42 in this application can adopt the activation ejector pin disclosed in CN212235742U, a perfluorohexanone fire extinguisher cabinet. Alternatively, the driving structure in this application can adopt the gas-driven valve disclosed in CN212214445U, a fire extinguisher gas-driven valve, and the ejector pin 42 in this application can also adopt the activation ejector pin disclosed in CN212214445U, a fire extinguisher gas-driven valve.

[0042] The axis of the inlet can coincide with the axis of the receiving cavity 11, and one end of the inlet seal 2 is inserted into the inlet.

[0043] Specifically, the imported seal 2 can be inserted into the inlet in a quick-connect manner, replacing the threaded interface of the solenoid valve in the prior art. This application facilitates production and assembly and can improve production efficiency.

[0044] The working power of the electric explosion valve 43 can be 0.3~0.7W, and the power supply voltage of the electric explosion valve 43 is 3~7V.

[0045] Specifically, the operating power of the electric explosion valve 43 can be 0.5W, and the power supply voltage of the electric explosion valve 43 can be 5V. Therefore, the puncture drive 4 of this application only requires DC 5V power supply and an operating power of 0.5W. The drive structure activates the sealing diaphragm 32, which is punctured. Considering the extreme case, if 5 drive structures are activated simultaneously, the total power is approximately 2.5W.

[0046] Specifically, in this application, both the inlet seal 2 and the outlet seal 3 can be quick-connect structures. The inlet seal 2 is inserted into the inlet, and the outlet seal 3 is inserted into the outlet 12. That is, quick-connect structures can be used at both the inlet and outlet 12 of the valve body 1. This application can be a 1-inlet, 8-outlet structure. The number of outlets 12 in this application should preferably be controlled to within 8 outlets 12, that is, this application can be a 1-inlet, 8-outlet structure.
