Description

Technical Field

[0001] The present invention relates to the technical field of automatic monitoring and alarm devices, and in particular to an automatic monitoring and alarm device for fire protection in a lithium-ion battery energy storage power station. Background Art

[0002] Lithium-ion battery energy storage power stations are power facilities that use lithium-ion batteries to store and release electrical energy to achieve peak load shifting and improve grid stability. Due to the inherent characteristics of lithium-ion batteries, abnormal conditions such as overcharging and short circuits can easily trigger internal chemical reactions, generating large amounts of heat and gas, leading to thermal runaway. Furthermore, the batteries in energy storage stations are large and closely packed. Once a fire occurs, it will spread rapidly and may also have a serious impact on the surrounding power supply, residents' lives, and the ecological environment. Therefore, fire protection is necessary. The automatic monitoring and alarm devices used for fire protection in lithium-ion battery energy storage power stations can continuously monitor key parameters such as battery temperature, voltage, current, and smoke concentration in real time. If an anomaly is detected, an alarm can be immediately issued and the information can be promptly transmitted to on-site personnel and remote monitoring centers. This provides a strong guarantee for the timely detection of fire hazards, the purchase of time for fire extinguishing and evacuation, and effectively reduces the losses caused by fire.

[0003] Existing automatic monitoring and alarm devices for fire protection in lithium-ion battery energy storage power stations are generally secured with bolts during installation and removal. These bolts require a significant amount of time to tighten individually during installation, and even more effort to unscrew during removal. This increases maintenance response time and reduces the timeliness and effectiveness of maintenance. Furthermore, frequent vibrations from equipment starting and stopping within the energy storage station, as well as from surrounding construction and traffic, can cause internal components to loosen and become loose, leading to inaccurate monitoring data, ineffective alarm functions, and difficulty in detecting fire hazards in a timely manner. Therefore, we propose an automatic monitoring and alarm device for fire protection in lithium-ion battery energy storage power stations. Summary of the Invention

[0004] The object of the present invention is to provide an automatic monitoring and alarm device for fire protection in a lithium-ion battery energy storage power station, so as to solve the problem that the existing automatic monitoring and alarm device for fire protection in a lithium-ion battery energy storage power station proposed in the above background art is generally fixed with bolts during installation and disassembly. It takes a lot of time to tighten the bolts one by one during installation, and it takes even more effort to unscrew them during disassembly, which increases the response time of maintenance and reduces the timeliness and effectiveness of maintenance. At the same time, when the equipment in the energy storage station is frequently started and stopped, causing vibration, or when there is vibration caused by construction or traffic in the surrounding area, the internal components of the device are prone to loosening and poor contact, resulting in inaccurate monitoring data, failure of the alarm function, and difficulty in timely detection of fire hazards.

[0010] Preferably, the motor is fixedly connected to an output shaft through an output end on one side thereof, and one side of the output shaft is fixedly connected to one end of a single-thread screw through a coupling, a long thread groove is provided in the center of one side of the telescopic column, one end of the single-thread screw passes through the interior of the long thread groove and is threadedly connected to its inner wall, a second guide groove is provided on one side of the top and bottom of the hollow column, and a second guide block is fixedly connected to one side of the top and bottom of the telescopic column, and the top and bottom of the two second guide blocks respectively extend to the interior of the two second guide grooves and are slidably connected to the inner walls of the second guide grooves.

[0011] Preferably, the sensor group includes a temperature sensor, a smoke sensor, a gas sensor and a voltage and current sensor respectively, and the interior of the box is fixedly installed with a power supply module, a signal receiving module, a communication transmission module and a control module. The control module is electrically connected to the sound and light alarm, the motor, the monitor, the sensor group, the power supply module, the signal receiving module and the communication transmission module through wires.

[0012] A method for using an automatic monitoring and alarm device for fire protection in a lithium-ion battery energy storage power station comprises the following steps: Step 1: During installation, align the plug-in plate at the bottom of the box with the slot on the shock absorber plate, push the plug-in plate into the slot, turn the knob, and drive the first bevel gear to rotate through the rotating rod. The first bevel gear drives the second bevel gear to rotate, thereby rotating the double-thread screw. The rotation of the double-thread screw causes the two nut plates to move relative to each other, and the nut plate drives the extension plate to move. The extension plate drives the card plate to move, so that the card plate is stuck in the slot on the connecting block to complete the fixed installation of the box.

[0013] Step 2: Then, control the motor to drive the single-thread screw to rotate. Through the threaded connection between the single-thread screw and the long thread groove, the single-thread screw extends the telescopic column toward the battery compartment during the rotation process until the monitor and sensor group on the mounting plate move through the monitoring slot into the battery compartment and then stop the motor.

[0014] Step three, when the device is vibrated, the shock absorber plate moves downward under the impact force, and the shock absorber plate drives the upper hinge plate to move downward. The upper hinge plate pushes the slider to slide in the slide groove through the movable connecting rod. The slider compresses the first spring, and the first spring generates elastic force to resist vibration. At the same time, the shock absorber plate moves downward to compress the damping rod. The damping rod consumes vibration energy through its own damping characteristics to play a shock-absorbing role. During the downward movement of the shock absorber plate, the two sides squeeze the sliding sleeve, and the sliding sleeve slides on the sliding rod and compresses the second spring. The second spring generates elastic force to further buffer the vibration, so that the box and monitoring equipment on the shock absorber plate remain relatively stable, reducing the impact of vibration on the monitoring equipment.

[0015] Step 4: The temperature sensor, smoke sensor, gas sensor, and voltage and current sensor in the sensor group monitor the temperature, smoke concentration, gas composition, voltage and current and other parameters in the battery compartment in real time. The sensor group transmits the monitored data to the signal receiving module in the box, and the signal receiving module transmits the data to the control module. The control module analyzes and processes the received data. When the monitoring data exceeds the set safety threshold, the control module determines that a dangerous situation such as fire may occur. The control module immediately activates the sound and light alarm to sound an alarm, and at the same time sends the alarm information to the terminal device of the relevant management personnel through the communication transmission module to remind the management personnel to deal with it in time; and the control module starts the monitor to monitor the situation in the battery compartment in real time, providing the management personnel with on-site images to accurately judge and deal with the dangerous situation.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The automatic monitoring and alarm device for fire protection of lithium-ion battery energy storage power station is designed with a base, a shock-absorbing plate, a slide groove, a slider, a first spring, an upper hinge plate, a lower hinge plate, a movable connecting rod, a damping rod, a sliding rod, a sliding sleeve and a second spring. When encountering vibration, the various components in the base cooperate to trigger the shock-absorbing mechanism. The shock-absorbing plate moves under force, driving the upper hinge plate to push the slider through the movable connecting rod to compress the first spring. At the same time, the damping rod is compressed, and its own damping characteristics are used to consume vibration energy. The movement of the shock-absorbing plate will also squeeze the sliding sleeve, causing the sliding sleeve to slide on the sliding rod and compress the second spring to further absorb vibration. The joint action of various components effectively reduces the impact of vibration on the box and monitoring equipment, ensures the accuracy of monitoring data and the stable operation of the equipment, effectively avoids problems such as component displacement and line loosening due to vibration in the device, ensures the stable operation of the fire monitoring and alarm function, reduces maintenance costs and failure risks, plug-in board, slot, vertical plate, double-thread screw, nut plate, rotating rod, knob, first bevel gear, second bevel gear, extension The design of the plate, connecting block, slot, card plate, hollow column, telescopic column, motor and single-thread screw, the plug-in plate and slot provide preliminary positioning and guidance for the installation of the box. During installation, you only need to insert the plug-in plate accurately into the slot to quickly achieve the initial placement of the box on the shock-absorbing plate. There is no need for complicated alignment operations, which greatly improves the installation efficiency. When the box needs to be fixed, turn the knob to drive the first bevel gear to rotate through the rotating rod, and then drive the second bevel gear to drive the double-thread screw to rotate, so that the two nut plates move relative to each other, pushing the extension plate and the card plate into the slot to complete the firm locking. When disassembling, turn the knob in the opposite direction to disengage the card plate from the slot and easily remove the box. The operation is simple and quick. When it is necessary to adjust the monitoring position or perform equipment maintenance, the single-thread screw can be driven to rotate by controlling the motor to achieve the extension and retraction of the telescopic column, so that the monitor and sensor group can be conveniently moved out of or in the battery compartment without large-scale disassembly of the entire device, further improving the convenience of equipment disassembly and assembly and maintenance efficiency.

[0028] A method for using an automatic monitoring and alarm device for fire protection in a lithium-ion battery energy storage power station comprises the following steps: Step 1. During installation, align the plug plate 18 at the bottom of the box body 17 with the slot 19 on the shock absorber plate 5, push the plug plate 18 into the slot 19, turn the knob 24, and drive the first bevel gear 25 to rotate through the rotating rod 23. The first bevel gear 25 drives the second bevel gear 26 to rotate, thereby rotating the double-tooth screw 21. The rotation of the double-tooth screw 21 causes the two nut plates 22 to move relative to each other, and the nut plate 22 drives the extension plate 28 to move. The extension plate 28 drives the card plate 31 to move, so that the card plate 31 is stuck in the card slot 30 on the connecting block 29, completing the fixed installation of the box body 17.

[0029] Step 2. Then, control the motor 37 to drive the single-thread screw 38 to rotate. Through the threaded connection between the single-thread screw 38 and the long thread groove, the single-thread screw 38 extends the telescopic column 36 toward the battery compartment 2 during the rotation process until the monitor 42 and the sensor group 43 on the mounting plate 41 move through the monitoring slot 44 into the battery compartment 2 and then stop the motor 37.

[0030] Step three, when the device is vibrated, the shock-absorbing plate 5 moves downward under the impact force, and the shock-absorbing plate 5 drives the upper hinge plate 9 to move downward. The upper hinge plate 9 pushes the slider 7 to slide in the slide groove 6 through the movable connecting rod 11, and the slider 7 compresses the first spring 8. The first spring 8 generates elastic force to resist vibration. At the same time, the shock-absorbing plate 5 moves downward to compress the damping rod 12. The damping rod 12 consumes vibration energy through its own damping characteristics and plays a shock-absorbing role. In the process of moving downward, the shock-absorbing plate 5 squeezes the sliding sleeve 15 on both sides. The sliding sleeve 15 slides on the sliding rod 14 and compresses the second spring 16. The second spring 16 generates elastic force to further buffer the vibration, so that the box 17 and the monitoring equipment on the shock-absorbing plate 5 remain relatively stable, reducing the impact of vibration on the monitoring equipment.

[0031] Step 4: The temperature sensor, smoke sensor, gas sensor and voltage and current sensor in the sensor group 43 monitor the temperature, smoke concentration, gas composition and voltage and current and other parameters in the battery compartment 2 in real time. The sensor group 43 transmits the monitored data to the signal receiving module in the box 17. The signal receiving module transmits the data to the control module. The control module analyzes and processes the received data. When the monitoring data exceeds the set safety threshold, the control module determines that a dangerous situation such as fire may occur. The control module immediately starts the sound and light alarm 34 to sound an alarm, and at the same time sends the alarm information to the terminal device of the relevant management personnel through the communication transmission module to remind the management personnel to deal with it in time; and the control module starts the monitor 42 to monitor the situation in the battery compartment 2 in real time, and provide the management personnel with on-site pictures to accurately judge and deal with the dangerous situation.

When encountering vibration, the various components in the base 3 cooperate to trigger the shock-absorbing mechanism, and the shock-absorbing plate 5 moves under force, driving the upper hinge plate 9 to push the slider 7 through the movable connecting rod 11 to compress the first spring 8. At the same time, the damping rod 12 is compressed, and the vibration energy is consumed by its own damping characteristics. The movement of the shock-absorbing plate 5 will also squeeze the slide The sleeve 15 makes the sliding sleeve 15 slide on the sliding rod 14 and compress the second spring 16 to further absorb the vibration. The various components work together to effectively reduce the impact of vibration on the box 17 and the monitoring equipment, ensure the accuracy of the monitoring data and the stable operation of the equipment, effectively avoid the problems of component displacement and line loosening due to vibration in the device, ensure the stable operation of the fire monitoring alarm function, reduce maintenance costs and failure risks, plug-in board 18, slot 19, vertical plate 20, double-thread screw 21, nut plate 22, rotating rod 23, knob 24, first bevel gear 25, second bevel gear 26, extension plate 28, The design of the connecting block 29, the card slot 30, the card plate 31, the hollow column 35, the telescopic column 36, the motor 37 and the single-thread screw 38, the plug plate 18 and the slot 19 provide preliminary positioning and guidance for the installation of the box 17. During installation, it is only necessary to accurately insert the plug plate 18 into the slot 19 to quickly achieve the preliminary placement of the box 17 on the shock absorber plate 5 without complicated alignment operations, which greatly improves the installation efficiency. When it is necessary to fix the box 17, turn the knob 24 to drive the first bevel gear 25 to rotate through the rotating rod 23, and then drive the second bevel gear 26 to drive the double-thread screw 21 to rotate, so that The two nut plates 22 move relative to each other, pushing the extension plate 28 and the card plate 31 into the card slot 30 to complete a firm locking. When disassembling, the card plate 31 can be disengaged from the card slot 30 by rotating the knob 24 in the opposite direction, and the box body 17 can be easily removed. The operation is simple and quick. When it is necessary to adjust the monitoring position or perform equipment maintenance, the single-thread screw 38 can be driven to rotate by controlling the motor 37 to realize the extension and retraction of the telescopic column 36, and the monitor 42 and the sensor group 43 can be conveniently moved out of or into the battery compartment 2 without large-scale disassembly of the entire device, further improving the convenience of equipment disassembly and assembly and the maintenance efficiency.

7. A method for using the automatic monitoring and alarm device for fire protection in a lithium-ion battery energy storage power station according to any one of claims 1 to 6, characterized in that: The steps include: Step 1: When installing, align the plug plate (18) at the bottom of the box (17) with the slot (19) on the shock-absorbing plate (5), push the plug plate (18) into the slot (19), turn the knob (24), drive the first bevel gear (25) to rotate through the rotating rod (23), and the first bevel gear (25) drives the second bevel gear (26) to rotate, thereby rotating the double-tooth screw (21), and the rotation of the double-tooth screw (21) causes the two nut plates (22) to move relative to each other, and the nut plate (22) drives the extension plate (28) to move, and the extension plate (28) drives the card plate (31) to move, so that the card plate (31) is stuck in the card slot (30) on the connecting block (29), completing the fixed installation of the box (17); Step 2: Next, the motor (37) is controlled to drive the single-thread screw (38) to rotate. Through the threaded connection between the single-thread screw (38) and the threaded long groove, the single-thread screw (38) causes the telescopic column (36) to extend toward the battery compartment (2) during the rotation process until the monitor (42) and the sensor group (43) on the mounting plate (41) pass through the monitoring slot (44) and move into the battery compartment (2), and then the motor (37) is stopped. Step three, when the device is vibrated, the shock-absorbing plate (5) moves downward under the impact force, and the shock-absorbing plate (5) drives the upper hinge plate (9) to move downward. The upper hinge plate (9) pushes the slider (7) to slide in the slide groove (6) through the movable connecting rod (11). The slider (7) compresses the first spring (8), and the first spring (8) generates elastic force to resist vibration. At the same time, the shock-absorbing plate (5) moves downward to compress the damping rod (12). The damping rod (12) consumes vibration energy through its own damping characteristics and plays a shock-absorbing role. During the downward movement of the shock-absorbing plate (5), both sides squeeze the sliding sleeve (15), and the sliding sleeve (15) slides on the sliding rod (14) and compresses the second spring (16). The second spring (16) generates elastic force to further buffer the vibration, so that the box (17) on the shock-absorbing plate (5) and the monitoring equipment remain relatively stable, reducing the impact of vibration on the monitoring equipment; Step 4: The temperature sensor, smoke sensor, gas sensor and voltage and current sensor in the sensor group (43) monitor the temperature, smoke concentration, gas composition and voltage and current parameters in the battery compartment (2) in real time. The sensor group (43) transmits the monitored data to the signal receiving module in the box (17). The signal receiving module transmits the data to the control module. The control module analyzes and processes the received data. When the monitoring data exceeds the set safety threshold, the control module determines that a dangerous situation such as fire may occur. The control module immediately starts the sound and light alarm (34) to sound an alarm. At the same time, the alarm information is sent to the terminal device of the relevant management personnel through the communication transmission module to remind the management personnel to deal with it in time. The control module also starts the monitor (42) to monitor the situation in the battery compartment (2) in real time and provide the management personnel with a scene picture so that they can accurately judge and deal with the dangerous situation.
