Description

Technical Field

[0001] The present invention relates to the technical field of new energy storage technology, and in particular to a fire fighting system for an energy storage container and a control method thereof. Background Art

[0002] With the transformation of the global energy structure and the large-scale replacement of renewable energy, the application of energy storage systems in the energy field is attracting more and more attention. However, the safety of energy storage systems has always been one of the bottlenecks restricting its development. As the last passive defense system, fire protection has a direct impact on the healthy development of the energy storage industry through reasonable design, material selection, layout and construction. The importance of fire protection in energy storage systems is becoming increasingly prominent. Only by strengthening the fire protection construction of energy storage systems can we ensure the safe operation of energy storage systems and promote sustainable development in the energy field.

[0003] However, the existing technology has the following problems: it is difficult to monitor and report information in real time, it is difficult to make corresponding feedback and other actions in time when problems occur, and the security is low. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a fire protection system for an energy storage container and a control method thereof, which solve the following problems existing in the prior art: difficulty in real-time monitoring and reporting information, difficulty in making corresponding feedback and other actions in time when problems occur, and low safety.

[0005] The technical solution adopted by the present invention to solve the above problems is:

[0006] A fire protection system for an energy storage container comprises a fire controller, a detection device, an alarm device and a fire extinguishing start device. The fire controller is communicatively connected with the detection device, the alarm device and the fire extinguishing start device respectively.

[0007] As a preferred technical solution, the detection device includes a smoke detector and a temperature detector, and the fire controller is communicatively connected with the smoke detector and the temperature detector respectively.

[0008] As a preferred technical solution, the alarm device includes an alarm bell, an audible and visual alarm, and a do not enter indicator light. The fire controller is communicatively connected to the alarm bell, the audible and visual alarm, and the do not enter indicator light.

[0009] As a preferred technical solution, the detection device includes a composite gas detector and an air inlet / exhaust device which are respectively communicatively connected to the fire controller, and the composite gas detector is communicatively connected to the air inlet / exhaust device.

[0010] As a preferred technical solution, it includes an automatic / manual conversion device which is communicatively connected to the fire controller.

[0011] In the control method of the fire protection system for an energy storage container, when the values ​​detected by the smoke detector and the temperature detector reach the alarm value, the fire controller sends out a first type fire signal, the alarm sounds and indicates the location of the fire.

[0012] In the control method for a fire protection system of an energy storage container, when the composite gas detector detects that the gas concentration exceeds the alarm value, the composite gas detector feeds back a signal to start the air intake / exhaust device.

[0013] As a preferred technical solution, if the values ​​detected by the smoke detector and the temperature detector do not reach the alarm values ​​at the same time and the composite gas detector detects that the gas concentration exceeds the alarm value, the fire controller sends out a first type of fire signal, the alarm bell sounds and indicates the location of the fire, and after the gas concentration returns to below the alarm value, the air inlet / exhaust device is closed; if the values ​​detected by the smoke detector and the temperature detector both reach the alarm values ​​and the composite gas detector detects that the gas concentration exceeds the alarm value, the fire controller sends out a second type of fire signal, the sound and light alarm sounds, and the alarm "do not enter" indicator light operates as a prompt.

[0014] The control method of the fire protection system for the energy storage container includes the following modes:

[0015] Automatic control mode:

[0016] When the first type of fire signal occurs, the alarm will sound to indicate the location of the fire, and the fire controller will send out a linkage output signal to alert the staff;

[0017] When a second type of fire signal occurs, the fire controller enters the delay stage. At the same time, the fire controller sends out a linkage output signal to shut down the air inlet / exhaust device and all power supplies in the protection zone except emergency lighting. After the automatic delay set time, the fire controller controls the fire extinguishing starting device in the protection zone to work and carry out fire extinguishing operations.

[0018] The control method of a fire protection system for an energy storage container includes a manual start button provided in a fire controller and an emergency start button connected to the fire controller. The control method includes the following modes:

[0019] Manual control mode:

[0020] When a fire occurs in the protection area, the fire controller only sends out an alarm signal, but does not send out a signal to control the operation of the fire extinguishing starting device. After the duty personnel confirm the fire alarm, they press the manual start button or the emergency start button in the fire controller to make the fire controller control the fire extinguishing starting device to operate and carry out the fire extinguishing operation.

[0021] When a second-class fire signal alarm occurs and it is found that there is no need to control the fire extinguishing starting device to perform fire extinguishing operations within the delay time, press the manual emergency stop button or the emergency stop button in the fire controller to make the fire controller control the fire extinguishing starting device to stop working.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The present invention monitors and reports information in real time through the detectors of the fire protection system, and takes corresponding feedback and other actions in time when problems occur, thereby improving the safety of system operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described in detail below in conjunction with embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0031] Example 1

[0032] like Figures 1 to 6 As shown, the present invention provides a fire protection system for an energy storage container and a control method thereof, thereby solving the operational safety of the existing container-type energy storage system. The detectors of the fire protection system monitor and report information in real time, and provide corresponding feedback in time when problems occur, thereby providing the safety of system operation.

[0033] To achieve the above-mentioned objectives, the present invention provides a fire protection system for an energy storage container and a control method thereof. The system includes: a fire controller, a smoke (smoke sensing) detector, a temperature (temperature sensing) detector, a composite gas detector, an automatic / manual conversion device, a fire extinguishing starting device, an air intake / exhaust device, etc.

[0034] The data detected by the fog (smoke) detector, temperature (heat sensing) detector, and composite gas detector are sent to the fire controller, and the fire controller makes corresponding alarm actions according to the internal control logic;

[0035] The fire controller can communicate with external equipment (such as EMS, BMS, PCS, fire control room) in real time via RS485 to report fire data, etc.

[0036] When the values ​​detected by both the smoke (smoke) detector and the temperature (temperature) detector reach the alarm value, the fire controller sends out a first-class fire signal and a first-level alarm bell to indicate the location of the fire and alert the staff;

[0037] When the composite gas detection circuit detects that the gas concentration exceeds the alarm value, the detector feeds back the corresponding signal, starts the air inlet / exhaust device, and when the values ​​detected by the smoke (smoke) detector and the temperature (temperature) detector do not reach the alarm value at the same time, the fire controller sends out a first-class fire signal and a first-level alarm bell to indicate the location of the fire and remind the staff to pay attention. After the gas concentration returns to the alarm value range, the air inlet / exhaust device is closed;

[0038] When the values ​​detected by the smoke (smoke) detector and the temperature (temperature) detector both reach the alarm value and the composite gas detector detects that the gas concentration exceeds the alarm value, the fire controller sends out a second-class fire signal, the second-level alarm sound and light alarm will be activated, and the second-level alarm do not enter indicator light will be activated;

[0039] When the fire controller is in automatic control mode, it starts to enter the delay phase (0-30S adjustable). After the delay, it controls the fire extinguishing start device in the corresponding protection zone to carry out fire extinguishing operations in the fire zone.

[0040] When the alarm controller is in manual state, the alarm controller only sends out an alarm signal but does not output an action signal. After the on-duty personnel confirms the fire, they can press the manual start button in the fire controller or activate the emergency start button outside the protection area door to start the fire extinguishing device and carry out fire extinguishing operations in the fire area.

[0041] Automatic control: When no one is in the protection area, turn the control mode switch in the fire controller to the "automatic" position, and the system will enter the automatic control state. When the first type of fire signal occurs, an alarm will be issued to indicate the location of the fire, and a linkage output signal will be issued at the same time to remind the staff to pay attention;

[0042] When a second type of fire signal occurs, the fire controller begins to enter the delay stage and sends out a linkage output signal to shut down the linkage equipment (the air inlet / exhaust device is closed) and all power supplies in the protection area except emergency lighting.

[0043] After an automatic delay of 30 seconds (adjustable), the fire extinguishing start device in the corresponding protection zone is controlled to work and fire extinguishing operations are carried out in the fire zone;

[0044] Manual control: When someone is working or on duty in the protection zone, turn the control mode switch in the fire controller to the "manual" position, and the system enters the manual control state. When a fire occurs in the protection zone, press the manual start button in the fire controller, or start the emergency start button outside the protection zone door, and the fire extinguishing start device can be controlled according to the above procedures to carry out fire extinguishing operations. In the automatic control state, electrical manual control can still be achieved.

[0045] When a second-category fire signal alarm occurs, if it is found that there is no need to control the fire extinguishing starting device to perform fire extinguishing operations within the delay time, you can press the manual emergency stop button in the fire controller, or press the emergency stop button outside the protection area door to prevent the issuance of the fire extinguishing command and stop the system from controlling the fire extinguishing starting device.

[0046] The present invention monitors and reports information in real time through the detectors of the fire protection system, and takes corresponding feedback and other actions in time when problems occur, thereby improving the safety of system operation.

[0047] As described above, the present invention can be preferably implemented.

[0048] All features disclosed in all embodiments in this specification, or steps in all methods or processes implicitly disclosed, except for mutually exclusive features and / or steps, can be combined and / or expanded or replaced in any manner.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. According to the technical essence of the present invention, within the spirit and principles of the present invention, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the present invention.
