Description

Technical Field

[0001] This invention relates to the field of fire detection equipment technology, specifically to a composite fire detection device for energy storage power stations. Background Technology

[0002] In today's energy sector, energy storage power stations play a vital role; however, their fire safety faces severe challenges. With the continuous development of energy storage technology and the continuous expansion of the scale of energy storage power stations, fire hazards are becoming increasingly prominent. Once a fire occurs, due to the special nature of the batteries and other equipment in the energy storage power station, the fire exhibits a variety of complex and dangerous characteristics.

[0003] A composite fire detection device for an energy storage power station, disclosed in application publication number CN119488683A, includes a mounting base. A water spray pipe is located in the center of the mounting base, and a conical shell is formed in the center of the water spray pipe. A conical body that can seal the water spray pipe is located inside the conical shell. Several smoke extraction mechanisms for absorbing smoke from the fire are arranged around the periphery of the conical shell. A water curtain forming mechanism for creating a water curtain barrier at the bottom of the conical shell is provided. The air intake control mechanism in the smoke extraction mechanism utilizes the deformation characteristics of a bimetallic strip when the temperature rises to automatically control the opening and closing of the air inlet, thereby accurately extracting smoke from the fire. The water curtain forming mechanism, through the cooperation between the upper sliding shell and the lower guide plate, flexibly adjusts the size of the water curtain nozzle according to the working state of the device, forming an effective water curtain barrier at the fire.

[0004] Existing composite fire detection devices for energy storage power stations use smoke and temperature detectors to sense temperature and smoke. However, these detectors employ ionization smoke sensors, which trigger alarms by monitoring changes in the concentration of suspended particles in the air, or by sensing abnormal ambient temperature through thermal elements. When the temperature exceeds a set threshold (typically 67-91℃), an alarm is activated. This approach is suitable for fire scenarios with little or no smoke but significant heat release. However, it lacks the ability to monitor characteristic gases such as hydrogen and carbon monoxide, making it difficult to provide early warnings during the smoldering stage (when CO concentration rises sharply). Furthermore, existing composite fire detection devices for energy storage power stations are typically installed with a single-piece structure or a complex connection structure, making disassembly and assembly complicated when internal maintenance is required. Summary of the Invention

[0005] This invention addresses the technical problem of existing technologies lacking combined monitoring of characteristic gases such as hydrogen and carbon monoxide, making it difficult to provide early warning of sudden increases in CO concentration during the smoldering stage. It offers a significantly different solution from existing technologies. Specifically, the purpose of this invention is to provide a composite fire detection device for energy storage power stations. This solves the problem mentioned in the background section where existing composite fire detection devices for energy storage power stations use smoke and temperature detectors to sense temperature and smoke. However, these smoke and temperature detectors employ ionization smoke sensors, triggering alarms by monitoring changes in the concentration of suspended particles in the air, or by sensing abnormal ambient temperature through a thermistor. When the temperature exceeds a set threshold (typically -℃), an alarm is activated. While suitable for fire scenarios with little smoke or no smoke but significant heat release, these devices lack combined monitoring of characteristic gases such as hydrogen and carbon monoxide, making it difficult to provide early warning of sudden increases in CO concentration during the smoldering stage.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a composite fire detection device for an energy storage power station, comprising an upper shell and a lower shell, wherein the lower end of the upper shell is fitted with the lower shell, and a monitoring mechanism is provided on the outer wall of the upper shell, the monitoring mechanism comprising a first bracket, a connecting block, a locking bolt, a support plate and a monitoring device;

[0007] The first bracket is fixed to the outer wall of the upper housing. A connecting block is slidably connected inside the first bracket. A locking bolt is threaded inside the first bracket. The end of the locking bolt is in contact with the connecting block. A support plate is fixed to the outer wall of the connecting block. A monitoring device is fixedly installed on the outer wall of the support plate by bolts.

[0008] Preferably, the outer wall of the lower housing is provided with a connecting mechanism, the connecting mechanism including a lever, a second bracket, a slide bar, a support plate, a first spring, a collar, and a bent rod;

[0009] The end of the actuating lever is rotatably connected to the lower housing via a pin. The outer wall of the wave lever is rotatably connected to the second bracket via a pin. The second bracket has a sliding rod and a support plate slidably connected inside. The lower end of the sliding rod is fixedly connected to the support plate. A first spring is sleeved on the outer wall of the sliding rod. The two ends of the first spring are respectively in contact with the support plate and the second bracket. A collar is fixedly connected to the upper end of the sliding rod. The collar is engaged with the outer wall of the bent rod. The end of the bent rod is fixedly connected to the upper housing.

[0010] Preferably, a plurality of suction mechanisms are fixedly installed on the outer wall of the upper housing, the suction mechanisms are connected to the exhaust pipe, and the exhaust pipe is fixed on the upper surface of the upper housing.

[0011] Preferably, a water spray pipe is fixedly connected to the upper part of the upper housing, and the outer walls of both the water spray pipe and the exhaust pipe are fixedly connected to the mounting base.

[0012] Preferably, a support rod is fixedly connected to the inner wall of the upper housing, the support rod is slidably connected to the outer wall of the armature, and a cone-shaped body is fixedly connected to the upper end of the armature.

[0013] Preferably, the outer wall of the cone is fitted to the upper shell, and a second spring is sleeved on the outer wall of the armature, with the two ends of the second spring respectively fitted to the support rod and the cone.

[0014] Preferably, an insulating shell is fixedly connected to the inside of the lower shell, an iron core is fixedly installed inside the insulating shell, and a coil is disposed in the cavity inside the insulating shell.

[0016] Preferably, the lower housing is internally threaded with a fourth bracket.

[0017] Preferably, a power module is fixedly installed inside the fourth bracket, and a lower contact piece is fixedly installed at the upper end of the power module.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The monitoring equipment is a pump-suction carbon monoxide detector. The pump-suction carbon monoxide detector has a built-in suction pump, which can actively extract gas from tens of meters away to detect carbon monoxide concentration. It supports the detection of single gas or four-in-one gas hydrogen, oxygen, carbon monoxide and hydrogen sulfide. It has a large screen display, audible and visual alarm and self-test function. It is suitable for industrial safety, fire emergency and other fields. When hydrogen, oxygen, carbon monoxide and hydrogen sulfide are generated, water will also be sprayed out for fire extinguishing. This means that the device does not lack the comprehensive monitoring of characteristic gases such as hydrogen and carbon monoxide, and can give early warning in the smoldering stage (sudden rise in CO concentration).

[0020] 2. Attach the upper housing to the top of the lower housing, and place the collar on the outer wall of the bent rod. Rotate the lever in the opposite direction, and the second bracket will move in the opposite direction and fit against the outer wall of the lower housing. At this time, the support plate will compress the first spring. Under the elastic action of the first spring, the support plate will have a downward sliding force, which in turn will cause the collar to move downward, so that the collar is tightly fitted on the outer wall of the bent rod. All four connecting mechanisms are operated in the same way to connect the upper and lower housings together, realizing the assembly of the device. When it is necessary to maintain the internal structure of the composite fire detection device of the energy storage power station, disassembly and assembly are relatively simple.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 9This invention provides a technical solution: a composite fire detection device for an energy storage power station, comprising an upper shell 1 and a lower shell 2. The lower end of the upper shell 1 is attached to the lower shell 2. A monitoring mechanism 3 is provided on the outer wall of the upper shell 1. The monitoring mechanism 3 can provide early warning during the smoldering stage (sudden increase in CO concentration). The monitoring mechanism 3 includes a first bracket 301, a connecting block 302, a locking bolt 303, a support plate 304, and a monitoring device 305. The first bracket 301 is fixed to the outer wall of the upper shell 1. Multiple first brackets 301 are provided. The connecting block 302 is slidably connected inside the first bracket 301. The connecting block 302 can be inserted into the interior of the first bracket 301 and can be removed from the interior of the first bracket 301. The locking bolt 303 is threaded inside the first bracket 301. Two locking bolts are provided for each first bracket 301. When bolt 303 and locking bolt 303 rotate, their relative positions change with those of the first bracket 301. The end of locking bolt 303 fits against connecting block 302, and the end of locking bolt 303 abuts against connecting block 302 to fix connecting block 302 inside the first bracket 301. Support plate 304 is fixed to the outer wall of connecting block 302. The positions of connecting block 302 and support plate 304 are relatively fixed. Monitoring device 305 is fixedly installed on the outer wall of support plate 304 by bolts. Monitoring device 305 is a pump-suction carbon monoxide detector. The pump-suction carbon monoxide detector has a built-in suction pump, which can actively extract gas from tens of meters away to detect carbon monoxide concentration. It supports single gas or four-in-one gas (hydrogen, oxygen, carbon monoxide, hydrogen sulfide) detection, and has a large screen display, audible and visual alarm and self-test function. It is suitable for industrial safety, fire emergency and other fields.

[0033] The monitoring device 305 is fixedly installed on the support plate 304 with bolts. Holding the monitoring device 305, the connecting block 302 is placed at the notch position on the upper end of the first bracket 301, corresponding to the notch position of the first bracket 301. The monitoring device 305 is pulled downwards, and the connecting block 302 slides downwards inside the first bracket 301 until it reaches the bottom. The locking bolt 303 is rotated, so that the end of the locking bolt 303 abuts against the connecting block 302, fixing the connecting block 302 inside the first bracket 301. This fixes the position of the monitoring device 305, thus completing the installation of the monitoring device 305. The monitoring device 305 is a pump-suction carbon monoxide detector. The pump-suction carbon monoxide detector has a built-in suction pump and can actively extract gas from tens of meters away to detect carbon monoxide. The device monitors carbon monoxide concentration and supports single-gas or four-gas (hydrogen, oxygen, carbon monoxide, and hydrogen sulfide) detection. It features a large-screen display, audible and visual alarms, and self-testing functions, making it suitable for industrial safety, fire emergency response, and other fields. When hydrogen, oxygen, carbon monoxide, and hydrogen sulfide are generated, water will also be sprayed for fire extinguishing, ensuring comprehensive monitoring of characteristic gases such as hydrogen and carbon monoxide. It can provide early warning during the smoldering stage (when CO concentration rises sharply). After fire extinguishing, the power module 19 causes the magnetism below the iron core 14 to disappear, and the second spring 12, under elastic action, causes the cone 11 to move upward. The cone 11 blocks the lower end of the internal water spray pipe 7 of the upper shell 1, awaiting the next fire detection and extinguishing task. This achieves effective detection and efficient fire extinguishing of fires in energy storage power stations, ensuring the safe operation of energy storage power stations.

[0034] The outer wall of the lower housing 2 is provided with a connecting mechanism 4. The connecting mechanism 4 facilitates the connection between the upper housing 1 and the lower housing 2, facilitates the disassembly and reassembly of the upper housing 1 and the lower housing 2, and facilitates the maintenance of the internal structure of the upper housing 1 and the lower housing 2. The connecting mechanism 4 includes a lever 401, a second bracket 402, a sliding rod 403, a support plate 404, a first spring 405, a collar 406, and a bent rod 407. The end of the lever 401 is rotatably connected to the lower housing 2 via a pin. The lever 401 can rotate relative to the lower housing 2. The outer wall of the lever 401 is rotatably connected to the second bracket 402 via a pin. The lever 401 can drive the second bracket 402 to move. The interior of the second bracket 402 is slidably connected. There is a sliding rod 403 and a support plate 404. The sliding rod 403 and the support plate 404 can slide inside the second bracket 402. The lower end of the sliding rod 403 is fixedly connected to the support plate 404. The sliding rod 403 and the support plate 404 move together. A first spring 405 is sleeved on the outer wall of the sliding rod 402. The two ends of the first spring 405 are respectively in contact with the support plate 404 and the second bracket 402. Under the elastic action, the first spring 405 can drive the support plate 404 to slide. A collar 406 is fixedly connected to the upper end of the sliding rod 402. The sliding rod 402 and the collar 406 move together. The collar 406 is engaged with the outer wall of the bent rod 407. The collar 406 can be engaged with the outer wall of the bent rod 407. The end of the bent rod 407 is fixedly connected to the upper housing 1.

[0035] When maintenance is required on the internal components of the composite fire detection device for the energy storage power station, the mounting base 8 is disassembled from its fixed position. The lever 401 is then moved, driving the second bracket 402 to move. The second bracket 402 then drives the support plate 404 and the sliding rod 403 to move. The sliding rod 403 moves together with the collar 406, causing the second bracket 402 to tilt upwards. At this point, the first spring 405 is no longer compressed. The collar 406 is then removed from the outside of the bent rod 407. Multiple connecting mechanisms use the same method to make the collar 406 and the bent rod 407 material distribution wheel. At this point, the positions of the upper housing 1 and the lower housing 2 are no longer relatively fixed. The upper housing 1 and the lower housing 2 are then disassembled and separated to perform internal maintenance on the composite fire detection device for the energy storage power station. After the internal maintenance of the composite fire detection device for the energy storage power station is completed, the upper housing 1 is placed on top of the lower housing 2, and the collar 406 is fitted onto the outer wall of the bent rod 407. The lever 401 is rotated in the opposite direction, and the second bracket 402 moves in the opposite direction and fits against the outer wall of the lower housing 2. At this time, the support plate 404 compresses the first spring 405. Under the elastic action of the first spring 405, the support plate 404 has a downward sliding force, which in turn causes the collar 406 to move downward, so that the collar 406 is tightly fitted onto the outer wall of the bent rod 407. All four connecting mechanisms 4 are operated in the same way to connect the upper housing 1 and the lower housing 2 together, realizing the assembly of the device. When it is necessary to maintain the internal of the composite fire detection device for the energy storage power station, disassembly and assembly are relatively simple.

[0036] Multiple suction mechanisms 5 are fixedly installed on the outer wall of the upper housing 1. The internal structure and working principle of the suction mechanism 5 are the same as those in the composite fire detection device for energy storage power stations published in application CN119488683A. The suction mechanism 5 is connected to the exhaust pipe 6, which is fixed on the upper surface of the upper housing 1. The position of the exhaust pipe 6 relative to the upper housing 1 is fixed. A water spray pipe 7 is fixedly connected to the upper part of the upper housing 1. The outer walls of both the water spray pipe 7 and the exhaust pipe 6 are fixedly connected to the mounting base 8. The positions of both the water spray pipe 7 and the exhaust pipe 6 relative to the mounting base 8 are fixed. The inner wall of the upper housing 1 is fixedly connected to... The support rod 9 is slidably connected to the outer wall of the armature 10. The armature 10 slides inside the support rod 9. A cone 11 is fixed to the upper end of the armature 10. The armature 10 and the cone 11 move together. The outer wall of the cone 11 fits against the upper housing 1. The cone 11 blocks the lower end of the water spray pipe 7 inside the upper housing 1. A second spring 12 is sleeved on the outer wall of the armature 10. The two ends of the second spring 12 fit against the support rod 9 and the cone 11 respectively. The second spring 12 can drive the cone 11 to move under the elastic action. The spring model is selected according to the actual use requirements to meet the working needs.

[0037] An insulating shell 13 is fixedly connected inside the lower housing 1. An iron core 14 is fixedly installed inside the insulating shell 13. A coil 15 is arranged in the cavity inside the insulating shell 13 and is located outside the iron core 14. A third bracket 16 is fixedly connected inside the lower housing 2. An upper contact piece 17 is fixedly installed inside the third bracket 16. A fourth bracket 18 is threadedly connected inside the lower housing 2. The fourth bracket 18 can be disassembled and separated from the lower housing 2. A power module 19 is fixedly installed inside the fourth bracket 18. A battery is installed outside the lower housing 2. The battery provides power to the power module 19. A lower contact piece 20 is fixedly installed at the upper end of the power module 19.

[0039] The composite fire detection device for this energy storage power station is used when performing composite fire detection at the energy storage power station;

[0040] Monitoring equipment installation phase:

[0041] The monitoring device 305 is fixedly installed on the support plate 304 with bolts. Holding the monitoring device 305, the connecting block 302 is placed at the notch position on the upper end of the first bracket 301 and corresponds to the notch position of the first bracket 301. The monitoring device 305 is pulled down, and the connecting block 302 slides down inside the first bracket 301. The connecting block 302 slides to the bottom inside the first bracket 301. The locking bolt 303 is rotated so that the end of the locking bolt 303 abuts against the connecting block 302. The locking bolt 303 fixes the connecting block 302 inside the first bracket 301, thereby fixing the position of the monitoring device 305 and realizing the installation of the monitoring device 305.

[0042] Connect the water spray pipe 7 to an external water source and the exhaust pipe 6 to an external pipe. Install the composite fire detection device for the energy storage power station at the required location using the mounting base 8. During normal operation of the energy storage power station, the device is in standby mode, and all mechanisms maintain their initial positions. In the event of a fire, the suction mechanism 5 first senses the temperature change and begins to draw out smoke. A battery is installed on the outside of the lower housing 2, which provides power to the power module 19. The power module 19 generates power through the lower contact 20 to the upper contact 17, and the power 17 causes the iron core 14 to generate magnetism. The iron core 14 attracts the armature 10, which in turn drives the cone 11 downwards and compresses the second spring 12. The outer wall of the cone 11 separates from the upper shell 1. Water enters the interior of the upper shell 1 through the water spray pipe and is then sprayed out through the water spray pipe inside the lower shell 2 for fire extinguishing. The monitoring device 305 is a pump-suction carbon monoxide detector. The pump-suction carbon monoxide detector has a built-in suction pump that can actively extract gas from tens of meters away to detect carbon monoxide concentration. It supports single gas or four-in-one gas (hydrogen, oxygen, carbon monoxide, and hydrogen sulfide). The device features a large-screen display, audible and visual alarms, and self-testing functions, making it suitable for industrial safety, fire emergency response, and other fields. It also sprays water to extinguish fires when a mixture of hydrogen, oxygen, carbon monoxide, and hydrogen sulfide is generated, ensuring comprehensive monitoring of characteristic gases such as hydrogen and carbon monoxide. It can provide early warning during the smoldering stage (when CO concentration rises sharply). After extinguishing the fire, the power module 19 removes the magnetism below the iron core 14, and the second spring 12, under its elastic action, causes the cone 11 to move upwards, spraying water into the interior of the upper housing 1. The lower end of pipe 7 is blocked to await the next fire detection and extinguishing mission, thereby achieving effective detection and efficient extinguishing of fires in the energy storage power station and ensuring the safe operation of the energy storage power station. The suction mechanism 5 first senses the temperature change and begins to draw smoke and mist. The monitoring device 305 is a pump-suction carbon monoxide detector. The pump-suction carbon monoxide detector has a built-in suction pump, which can actively draw gas from tens of meters away to detect carbon monoxide concentration. It supports single gas or four-in-one gas (hydrogen, oxygen, carbon monoxide, hydrogen sulfide) detection, realizing a composite fire detection device for the energy storage power station.

[0043] Device assembly / disassembly phase:

[0044] When maintenance is required on the internal components of the composite fire detection device for the energy storage power station, the mounting base 8 is disassembled from its fixed position. The lever 401 is then moved, driving the second bracket 402 to move. The second bracket 402 then drives the support plate 404 and the sliding rod 403 to move. The sliding rod 403 moves together with the collar 406, causing the second bracket 402 to tilt upwards. At this point, the first spring 405 is no longer compressed. The collar 406 is then removed from the outside of the bent rod 407. Multiple connecting mechanisms use the same method to make the collar 406 and the bent rod 407 material distribution wheel. At this point, the positions of the upper housing 1 and the lower housing 2 are no longer relatively fixed. The upper housing 1 and the lower housing 2 are then disassembled and separated to perform internal maintenance on the composite fire detection device for the energy storage power station. After the internal maintenance of the composite fire detection device for the energy storage power station is completed, the upper housing 1 is placed on top of the lower housing 2, and the collar 406 is fitted onto the outer wall of the bent rod 407. The lever 401 is rotated in the opposite direction, and the second bracket 402 moves in the opposite direction and fits against the outer wall of the lower housing 2. At this time, the support plate 404 compresses the first spring 405. Under the elastic action of the first spring 405, the support plate 404 has a downward sliding force, which in turn causes the collar 406 to move downward, so that the collar 406 is tightly fitted onto the outer wall of the bent rod 407. All four connecting mechanisms 4 are operated in the same way to connect the upper housing 1 and the lower housing 2 together, realizing the assembly of the device. When it is necessary to maintain the internal of the composite fire detection device for the energy storage power station, disassembly and assembly are relatively simple.
