Description

Technical Field

[0001] This invention relates to the field of energy storage power station protection technology, specifically an automatic protection system for energy storage power stations. Background Technology

[0002] Energy storage power stations are facilities where energy storage batteries store electrical energy. They are needed at the generation, grid, and user sides to store energy, helping to smooth intermittent energy output from the generation side, assisting the grid in peak shaving and valley filling, and promoting energy autonomy and optimization for users. The main equipment of an energy storage power station is the energy storage cabinet, which mainly consists of battery modules, energy storage converters, battery management systems, and energy management systems. Currently, most energy storage power stations use electrochemical energy storage technology, which poses a certain risk of fire and explosion. If the energy storage cabinet experiences thermal runaway, it will release large amounts of flammable and toxic gases, potentially leading to fire or even explosion. To reduce the damage caused by fires at energy storage power stations, fire extinguishing systems are installed to prevent the fire from spreading further and to protect the safety of people and property in the surrounding area to the greatest extent possible. However, many problems and shortcomings still exist at present.

[0003] There is a lack of efficient fire extinguishing methods specifically designed for the characteristics of fires in energy storage power stations. Once a fire occurs, the traditional method of spraying liquids or gases onto the fire point for cooling and extinguishing is still relied upon. However, when a chemical battery catches fire, it releases a large amount of heat and gas in a short period of time, and the temperature rises rapidly. Traditional fire extinguishing methods are no longer able to extinguish the fire efficiently and quickly.

[0004] In addition to traditional liquid and gas extinguishing methods, covering fire extinguishing measures can effectively isolate the burning material from the surrounding air, thereby achieving the purpose of rapid fire extinguishing. However, existing covering fire extinguishing measures still require manual operation, which is dangerous and requires professional firefighters to operate, thus preventing the fire from being extinguished in the first instance.

[0005] When an energy storage battery catches fire, the heat released can cause the edges of the covering to curl up, making it impossible to effectively cover the fire and greatly affecting the firefighting effect. This is especially true when there is wind in the surrounding environment, making it impossible for people to carry out the covering operation. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic protection system for energy storage power stations to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An automatic protection system for an energy storage power station, used for automatic fire suppression of energy storage cabinets, includes an automatic covering fire extinguishing device, wherein the automatic covering fire extinguishing device comprises:

[0009] The base is used to support the energy storage cabinet;

[0010] The base and energy storage cabinet are placed inside the frame guide rail;

[0011] The fire blanket has multiple connection points, which are slidably connected to the frame guide rail.

[0012] A traction mechanism, installed on the base and connected to multiple connection points, is used to pull the fire blanket downwards and retract it at the base, wrapping the energy storage cabinet inside the fire blanket.

[0013] The automatic protection system for energy storage power stations described above: the base is configured with two parallel support beams, the two ends of which form cantilever structures, and the cantilever structures are arranged in a circular shape.

[0014] The automatic protection system for energy storage power stations as described above: the frame rail includes two rail components arranged in a rectangular frame structure, and the two rail components are fixed at an intersection.

[0015] The automatic protection system for energy storage power stations as described above: the guide rail component includes a fixed traction guide rail arranged in a U-shaped structure, a movable traction guide rail is inserted into the end of the fixed traction guide rail away from the base, and an adjusting component for adjusting the length of the movable traction guide rail inserted into the fixed traction guide rail is installed between the fixed traction guide rail and the movable traction guide rail.

[0016] The automatic protection system for energy storage power stations as described above: the adjusting component includes an electric telescopic rod installed on the fixed traction guide rail, the movable end of the electric telescopic rod being fixed to the movable traction guide rail.

[0017] As described above, the automatic protection system for energy storage power stations has embedded tracks on both the fixed and movable guide rails. Traction rollers that are connected to the connection points on the fire blanket are rolled within the embedded tracks, and the traction rollers are connected to the traction mechanism.

[0018] The automatic protection system for energy storage power stations as described above: the traction mechanism includes a connecting ring installed below the base and fixed to the fixed traction guide rail, and a winding reel driven by a traction motor is rotatably installed inside the connecting ring;

[0019] It also includes a traction cable, one end of which is connected to the traction roller, and the other end passes through the connecting ring and is fixed to the winding reel.

[0020] The automatic protection system for energy storage power stations described above includes a fireproof isolation cover installed on the connecting ring for wrapping and protecting the traction motor.

[0021] The automatic protection system for energy storage power stations as described above: The automatic protection system for energy storage power stations further includes a prefabricated backup power firewall installed on the side of the energy storage cabinet, the prefabricated backup power firewall comprising:

[0022] Firewall body and battery embedded in the firewall body and electrically connected to the traction motor;

[0023] The smoke temperature sensor is electrically connected to the battery and communicates with the control unit of the traction motor.

[0024] The automatic protection system for energy storage power stations described above includes a prefabricated backup power firewall, which further includes a photovoltaic panel installed on the firewall body for charging the battery.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] The energy storage cabinet is placed inside the frame guide rail, and the fire blanket is folded and placed on the upper inner side of the frame guide rail. At this time, the fire blanket is at the top of the energy storage cabinet, which does not affect the normal use of the energy storage cabinet and plays a certain role in shading, preventing the energy storage cabinet from being exposed to direct sunlight for a long time. When the energy storage cabinet malfunctions and produces flammable and toxic gases, or even catches fire, the traction mechanism is activated, which pulls the fire blanket downward along the frame guide rail. At the same time, the movable traction guide rail descends, and the large amount of smoke generated when the fire occurs will be forcibly discharged outside the covered fire blanket and quickly cover the energy storage cabinet. The fire blanket is forcibly tightened to the bottom of the base, which can effectively isolate the energy storage cabinet from the outside world, reduce or eliminate the contact between oxygen and the fire source, thereby achieving the effect of extinguishing the fire and protecting the safety of surrounding personnel and property.

[0027] The firewall can effectively isolate the fire, prevent the fire from spreading, and protect the safety of surrounding people and property.

[0028] It can improve the safety of energy storage power stations, avoid and reduce property and personnel losses and casualties, and eliminate users' concerns about the safety of energy storage power stations. This automatic fire-fighting system can automatically take fire-fighting measures at the first moment of a fire, extinguishing the fire hazard in its infancy. At the same time, no personnel operation is required, which can reduce the harm to firefighters during the fire-fighting process.

[0029] It overcomes the disadvantages of traditional fire extinguishing methods in effectively controlling fires; avoids the drawback of fire extinguishing materials not being able to completely cover the fire point; overcomes the limitation of fire extinguishing methods using materials requiring operation by fire protection professionals; and eliminates the hidden dangers of malfunction and inadequacy of the fire extinguishing system built into the energy storage power station.

[0041] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0042] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0043] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0044] Please see Figures 1-7 In this embodiment of the invention, an automatic protection system for an energy storage power station is provided for automatic fire suppression of an energy storage cabinet 3. The system includes an automatic covering fire extinguishing device 1, comprising: a base 1-1 for supporting the energy storage cabinet 3; a frame rail, in which the base 1-1 and the energy storage cabinet 3 are placed; a fire blanket 1-10 having multiple connection points slidably connected to the frame rail; and a traction mechanism installed on the base 1-1 and connected to the multiple connection points, for pulling the fire blanket 1-10 downwards and retracting it at the base 1-1 to enclose the energy storage cabinet 3 within the fire blanket 1-10.

[0045] Place the energy storage cabinet 3 inside the frame guide rail, and fold the fire blanket 1-10 and place it on the upper inner side of the frame guide rail. At this time, the fire blanket 1-10 is at the top of the energy storage cabinet 3, which does not affect the normal use of the energy storage cabinet 3 and plays a certain role in shading, preventing the energy storage cabinet 3 from being exposed to direct sunlight for a long time. When the energy storage cabinet 3 malfunctions and produces flammable and toxic gases, or even catches fire, the traction mechanism is activated, which pulls the fire blanket 1-10 downward along the frame guide rail. The large amount of smoke generated when the fire occurs will be forcibly discharged outside the covered fire blanket 1-10 and quickly cover the energy storage cabinet 3, thereby effectively isolating the energy storage cabinet 3 from the outside world, reducing or eliminating the contact between oxygen and the fire source, thereby achieving the effect of fire extinguishing and protecting the safety of surrounding personnel and property.

[0046] Please see Figure 1 , Figure 2 and Figure 4 The aforementioned base 1-1 is configured as two parallel support beams, with cantilever structures at both ends of the support beams. The cantilever structures are circular in shape, ensuring that the fire blanket 1-10 can be stretched to the bottom of the energy storage cabinet 3, preventing the bottom edge of the fire blanket 1-10 from lifting up, and ensuring that the fire blanket 1-10 completely covers the energy storage cabinet 3.

[0047] Furthermore, the frame guide rail includes two guide rail components arranged in a rectangular frame structure, which are fixed together. The corners of the guide rail components are rounded to ensure smooth movement when the fire blanket 1-10 is stretched downwards.

[0048] Please see Figure 4The guide rail component includes a fixed traction guide rail 1-2 with a U-shaped structure. A movable traction guide rail 1-4 is inserted into one end of the fixed traction guide rail 1-2 away from the base 1-1. An adjustment component for adjusting the length of the movable traction guide rail 1-4 inserted into the fixed traction guide rail 1-2 is installed between the fixed traction guide rail 1-2 and the movable traction guide rail 1-4.

[0049] In one exemplary embodiment, the adjusting member includes an electric telescopic rod 1-9 mounted on the fixed traction guide rail 1-2, the movable end of the electric telescopic rod 1-9 being fixed to the movable traction guide rail 1-4.

[0050] The fixed guide rail 1-2 and the movable guide rail 1-4 are combined to form a guide rail component, which can be used for energy storage cabinets 3 of different heights, effectively improving the applicability. At the same time, when the fire blanket 1-10 is pulled, the electric telescopic rod 1-9 starts to move and retracts downward, driving the movable guide rail 1-4 down. When the movable guide rail 1-4 descends to near the top of the energy storage cabinet 3, the electric telescopic rod 1-9 stops working. This gradually reduces the wrapping space of the fire blanket 1-10 during the covering process, so that the large amount of smoke generated when the energy storage cabinet 3 catches fire will be forcibly expelled outside the covered fire blanket 1-10.

[0051] Please see Figures 4-7 Both the fixed traction guide rail 1-2 and the movable traction guide rail 1-4 have embedded slides. Traction rollers 1-7, which are connected to the connection position on the fire blanket 1-10, are rolled in the embedded slides. The traction rollers 1-7 are connected to the traction mechanism.

[0052] For example, in one embodiment, the traction mechanism includes a connecting ring 1-3 installed below the base 1-1 and fixed to the fixed traction guide rail 1-2, and a winding reel driven by a traction motor 1-5 is rotatably installed inside the connecting ring 1-3.

[0053] It also includes a traction cable 1-8, one end of which is connected to the traction roller 1-7, and the other end passes through the connecting ring 1-3 and is fixed to the winding reel.

[0054] In this embodiment, the traction motor 1-5 drives the winding reel to rotate. When the winding reel rotates, it winds up the traction cable 1-8, thereby driving the traction roller 1-7 to move along the embedded slide, which in turn drives the fire blanket 1-10 to be stretched downward, so as to realize the unfolding drive of the fire blanket 1-10.

[0055] Preferably, the connecting ring 1-3 is also equipped with a fireproof isolation cover 1-6 for wrapping and protecting the traction motor 1-5.

[0056] Further, please refer to Figures 1-3 The automatic protection system for the energy storage power station also includes a prefabricated backup power firewall 2 installed on the side of the energy storage cabinet 3. The prefabricated backup power firewall 2 includes:

[0057] Firewall body 2-1 and battery 2-3 embedded in firewall body 2-1 and electrically connected to traction motor 1-5. Battery 2-3 is set as a backup power source to provide power in emergency situations (such as power outage). Firewall body 2-1 can effectively isolate fire, prevent fire from spreading, and protect the safety of surrounding personnel and property.

[0058] The smoke temperature sensor 2-4 is electrically connected to the battery 2-3 and establishes communication with the control unit of the traction motor 1-5. The smoke temperature sensor 2-4 is used to detect the surrounding smoke and temperature to ensure that the traction motor 1-5 is started quickly when the energy storage cabinet 3 catches fire. The communication control between the control unit of the traction motor 1-5 and the smoke temperature sensor is a conventional technical means, so it will not be described in detail in this embodiment.

[0059] Preferably, the prefabricated backup power firewall 2 further includes a photovoltaic panel 2-2 installed on the firewall body 2-1. The photovoltaic panel 2-2 is used to charge the battery 2-3 to ensure that the battery 2-3 is always powered.

[0060] In summary, the automatic protection system for energy storage power stations provided by this invention can improve the safety of energy storage power stations, avoid and reduce property and personnel losses and injuries, eliminate users' concerns about the safety of energy storage power stations, and automatically carry out fire extinguishing measures at the first moment of a fire, extinguishing the fire hazard in its infancy. At the same time, no human operation is required, which can reduce the harm to firefighters during the firefighting process.

[0061] It overcomes the disadvantages of traditional fire extinguishing methods in effectively controlling fires; avoids the drawback of fire extinguishing materials not being able to completely cover the fire point; overcomes the limitation of fire extinguishing methods requiring professional fire protection personnel; and eliminates the hidden dangers of malfunctioning or insufficient fire protection systems in energy storage power stations.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
