Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of energy storage equipment, and particularly relates to a fire-fighting water filling valve and an energy storage equipment. BACKGROUND

[0002] With the rapid development of battery energy storage power stations, safety performance has become one of the key control projects of the energy storage system. In the charging or discharging process of lithium ion batteries, there may be a situation of thermal runaway, which affects the safety of the energy storage system.

[0003] In common energy storage products, such as energy storage cabinets or energy storage containers, a water spraying method is generally used for fire extinguishing. The commonly used fire sprinkler head currently mainly adopts a temperature sensing glass tube to block the water outlet of the sprinkler head. When the temperature sensing glass tube is heated and broken, the water outlet is opened to realize water discharge for fire extinguishing. However, due to the small size and insufficient strength of the temperature sensing glass tube, the size of the water outlet and the water pressure are limited, so that only a small flow water outlet can be used, and the flow is limited and the water pressure is insufficient, which seriously affects the fire extinguishing efficiency. The current solution is to use multiple fire sprinkler heads to make up for the small flow of a single sprinkler head, which increases the complexity of the water system and the production and construction cost. SUMMARY

[0004] The purpose of the embodiment of the application is to provide a fire-fighting water filling valve and an energy storage equipment, which solves the technical problem that the water discharge of the fire-fighting sprinkler head in the prior art is small and the water discharge pressure is limited, and cannot meet the rapid fire extinguishing requirement.

[0005] To achieve the above purpose, the technical scheme adopted by the application is to provide a fire-fighting water filling valve, comprising:

[0006] a water outlet pipe;

[0007] a valve cover covering the pipe opening of the water outlet pipe, the valve cover being pivotally connected to the pipe opening of the water outlet pipe;

[0008] a locking mechanism comprising a lever, an elastic member and a temperature sensing glass tube, the lever being arranged on the outer periphery of the water outlet pipe, one end of the lever being connected to the elastic member and the temperature sensing glass tube, the other end of the lever being provided with a hook portion; the elastic member and the temperature sensing glass tube are arranged between the outer wall of the water outlet pipe and one end of the lever, so that the other end of the lever abuts against the pipe opening of the water outlet pipe, and at the same time, the hook portion on the other end of the lever is buckled on the valve cover.

[0009] The fire-fighting water filling valve provided by the application has the beneficial effects that compared with the prior art, the structure of the traditional fire-fighting water valve with a temperature sensing glass tube is changed, and the temperature sensing glass tube is no longer used as a component for blocking the water outlet, so that the size of the pipe opening of the water outlet pipe is not limited. The fire-fighting water filling valve comprises a valve cover and a locking mechanism of the valve cover installed on the pipe opening of the water outlet pipe. The locking mechanism comprises a lever, an elastic member and a temperature sensing glass tube arranged outside the pipe opening of the water outlet pipe. The temperature sensing glass tube is arranged between one end of the lever and the outer wall of the water outlet pipe as a stopper, so that the elastic member is in an expanded state, and the other end of the lever is abutted against the pipe opening of the water outlet pipe, so that the hook part on the other end of the lever is buckled on the valve cover, and the valve cover tightly closes the pipe opening of the water outlet pipe. When the temperature sensing glass tube is broken by heat, the elastic member will shrink and restore due to the lack of support of the temperature sensing glass tube, and the one end of the lever connected with the elastic member is abutted against the outer wall of the water outlet pipe, and at the same time, the hook part on the other end of the lever is moved away from the valve cover, so that the buckling of the valve cover is released, and the valve cover is directly pushed away by the water flow in the water outlet pipe in the state without locking, so that the water outlet is realized. Therefore, the fire-fighting water filling valve is not limited by the blocking volume and the structural strength of the temperature sensing glass tube, and the pipe opening of the water outlet pipe can be increased according to the use requirements, as long as the cover area of the valve cover can match the size of the pipe opening. The locking mechanism is arranged outside the pipe opening of the water outlet pipe, and the lever and the components thereon are used to lock and fix the valve cover, so that the locking strength is effectively ensured, the larger water pressure can be borne, and the water outlet capacity of the entire fire-fighting water filling valve is increased.

[0010] In addition, compared with the water valve structure in the prior art in which an electromagnetic valve is used as a control valve body to open and close, the fire-fighting water filling valve is a pure mechanical structure, does not need to be connected with a control circuit, and does not need to be controlled online, so that the problem that the system is paralyzed, the fire alarm cannot be autonomously detected, and the valve cannot be timely opened for fire extinguishing is effectively avoided when the system fails or the control circuit is damaged. The fire-fighting water filling valve with the pure mechanical structure keeps the water outlet valve in a state that can be triggered to be opened, so that the working stability and reliability of the fire extinguishing equipment are effectively ensured.

[0011] The structure of the valve body is improved, the first connecting lug and the second connecting lug are arranged on the water outlet pipe, the first connecting lug and the second connecting lug are respectively arranged on the two sides of the pipe opening of the water outlet pipe, the middle part of the lever has a support part, the support part is connected with the first connecting lug through a rotating shaft, and the side part of the valve cover is connected with the second connecting lug through a rotating shaft. Therefore, the valve cover can be rotated on one side of the pipe opening of the water outlet pipe to be opened or closed on the pipe opening. The lever is arranged on the other side of the pipe opening of the water outlet pipe to realize the rotation of the lever, so that the hook part on the lever can be buckled on the valve cover closing the pipe opening to lock and fix the valve cover.

[0012] Optionally, on the lever, from the supporting part to one end of the lever, there are sequentially connected inclined plate and straight plate, the temperature sensing glass tube and the elastic member are supported between the straight plate and the outer wall of the water outlet pipe, the other end of the lever is abutted to the pipe opening of the water outlet pipe, and the hook part on the other end of the lever is buckled on the cover. In this way, the inclined plate and the straight plate on the lever form a space for arranging the temperature sensing glass tube outside the outer wall of the water outlet pipe, and the space is also for the deformation of the elastic member and the movement of the one end of the lever. The temperature sensing glass tube is supported between the outer wall of the water outlet pipe and the straight plate, so that the other end of the lever is abutted to the pipe opening of the water outlet pipe, and the hook part on the other end of the lever is buckled on the cover. The elastic member can be preferably a tension spring, and the elastic member is stretched between the outer wall of the water outlet pipe and the straight plate to keep the soft connection between the two. When the fire alarm occurs, the temperature sensing glass tube is broken by heat, the support between the outer wall of the water outlet pipe and the straight plate is lost, the elastic member is automatically restored, the straight plate is abutted to the outer wall of the water outlet pipe, and the hook part on the other end of the lever is removed from the cover, so that the cover is unlocked. The locking mechanism is a structure of pure mechanical components, and does not need online control to trigger the unlocking operation, so that the triggering stability of the locking mechanism is effectively ensured.

[0013] An improvement is made to the structure of the cover, the cover is provided with a counterweight, the counterweight is arranged on the side of the cover close to the second connecting lug, so that the center of gravity of the cover can be offset to the direction of the shaft connecting part of the cover and the pipe opening of the water outlet pipe, so that the cover can be naturally rotated to open to this side in the unlocked state, and the blocking of the water outlet is effectively reduced.

[0014] Optionally, the cover further comprises a connecting rod connected with the counterweight, the connecting rod is arranged on the cover and extends into the water outlet pipe or extends away from the pipe opening of the water outlet pipe, and the counterweight is arranged on the extended end of the connecting rod. In this way, the counterweight is supported on the cover by the connecting rod and away from the surface of the cover, so that the center of gravity is offset to the outside of the cover. It is equivalent to arranging a power outside the cover to apply a pushing force or a pulling force to the cover, so that the cover is rotated to open around the shaft connecting part, so that the opening range of the cover is further increased, and the blocking of the water outlet is reduced.

[0015] Another improvement is made to the structure of the cover, the cover is provided with a torsional spring at the shaft connecting part of the second connecting lug. The action force of the torsional spring can make the cover rotate to open as far as possible outside the pipe opening of the water outlet pipe, so that the blocking of the water outlet is also reduced.

[0016] Optionally, the valve cover further comprises a sealing ring and a convex ring for embedding into the outlet pipe orifice, and the sealing ring is sleeved on the convex ring. In this way, when the valve cover is closed to the outlet pipe orifice, the sealing ring is tightly pressed against the outlet pipe orifice, thereby improving the sealing effect.

[0017] An improvement is made to the buckling part of the lever and the valve cover. The buckling hook part of the lever is provided with a roller, and the valve cover is provided with a limiting slot for embedding the roller. When the buckling hook part is buckled on the cover, the roller is embedded in the limiting slot. The rotation of the roller is beneficial to improve the buckling or separation smoothness of the buckling hook part, avoid the occurrence of jamming to affect the timely opening of the valve cover, and thus improve the sensitivity of opening the valve cover.

[0018] Another improvement is made to the buckling part of the lever and the valve cover. The buckling hook part of the lever is provided with a roller, and the valve cover is provided with a frame composed of three edge convex ribs, and the frame forms a buckling slot for embedding the roller. The convex rib in the middle of the three edge convex ribs is provided with two side inclined surfaces arranged oppositely. In this way, the rotation of the roller is beneficial to improve the buckling or separation smoothness of the buckling hook part, thereby improving the sensitivity of opening the valve cover. In addition, the frame composed of the three edge convex ribs forms the buckling slot for embedding the roller, which limits the movement path of the roller and improves the guiding effect of the roller. The two edge convex ribs on both sides of the frame limit the movement path of the roller from both sides, and the convex rib in the middle of the three edge convex ribs buckles the roller. The two side inclined surfaces arranged oppositely on the middle convex rib are beneficial to the displacement of the roller buckling into or out of the frame.

[0019] The application also provides an energy storage device, which comprises a container body, a plurality of accommodating cavities for placing battery modules are arranged in the container body, a fire-fighting pipeline and a fire-fighting water filling valve are arranged on the container body, the fire-fighting pipeline respectively extends into each of the accommodating cavities, the outlet end of the fire-fighting pipeline is provided with the fire-fighting water filling valve, the outlet pipe orifice of the fire-fighting water filling valve is arranged to face downward, or the outlet pipe orifice of the fire-fighting water filling valve is arranged to face horizontally, and the rotation shaft connecting part of the valve cover and the outlet pipe is located on the side of the outlet pipe close to the bottom surface of the container body. On the one hand, the outlet pipe orifice of the fire-fighting water filling valve arranged on the fire-fighting pipeline extending into the accommodating cavity of the container body and arranged at the top position in the accommodating cavity is arranged to face downward, so that the valve cover is naturally opened downward and turned to one side when the valve cover is opened, thereby reducing the obstruction to the water outlet. On the other hand, the outlet pipe orifice of the fire-fighting water filling valve arranged on the fire-fighting pipeline extending into the accommodating cavity from the side wall of the accommodating cavity is arranged to face horizontally, and the rotation shaft connecting part of the valve cover and the outlet pipe is located on the side of the outlet pipe close to the bottom surface of the container body. In this way, the valve cover can be naturally spread downward after being opened, thereby reducing the obstruction to the water outlet. BRIEF DESCRIPTION OF DRAWINGS

[0043] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

[0044] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0045] It should be understood that the terms "length", "width", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0046] In addition, the terms "first", "second", etc. are used only for descriptive purposes and are not to be construed as indicating or implying relative importance or an indicated number of technical features. Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0047] The commonly used fire sprinkler mainly uses a temperature sensing glass tube to block the water outlet of the sprinkler. When the temperature sensing glass tube is broken by heat, the water outlet is opened to achieve water discharge for fire extinguishing. However, due to the small size and insufficient strength of the temperature sensing glass tube, the size of the water outlet and the water pressure are limited, so that only a small flow rate of water discharge nozzle can be used, which has limited flow rate and insufficient water pressure, seriously affecting the fire extinguishing efficiency. The current solution is to use multiple fire sprinklers to make up for the small flow rate of a single sprinkler, which increases the complexity of the water system and the production and construction cost.

[0048] In addition, in the related art, in order to solve the problem that the size of the pipe opening of the water outlet pipe and the water pressure are limited, a fire electromagnetic valve is used as an electrically controlled water valve structure to control the opening of the valve. Such valve does not limit the area of the blocked pipe opening, and can meet the demand of large water pressure and large flow rate. Such electromagnetic valve is connected to the fire control system of the entire device. When the fire sensing element in the fire control system detects temperature anomaly or fire alarm, it will control the electromagnetic valve to open the valve in time, so as to achieve the purpose of water discharge for fire extinguishing. However, the cost of using electromagnetic valve is high, the line structure of the entire system is complex, and online control is required. When the system fails or the control line is damaged, it will not be able to detect the fire alarm autonomously, and will not be able to open the valve in time for fire extinguishing, so the entire system is prone to paralysis.

[0049] Herein, the embodiments of the present application provide a novel fire water filling valve and energy storage equipment. First of all, it should be pointed out that the fire water filling valve of the present application includes but is not limited to the valve setting of the fire pipe provided on the energy storage equipment, and can also be provided on other carriers, such as the water outlet end of the fire pipe of buildings, large carriers, etc. As long as it is used in the scene of fire fighting demand, it is not limited here.

[0050] The energy storage equipment can be an energy storage cabinet, an energy storage container, etc. For example, the fire water filling valve of the present application is provided on the energy storage container.

[0051] The fire water filling valve of the present application is installed on the water outlet end of the fire pipe of an energy storage equipment. Please refer to Figure 1 、 Figure 2 and Figure 3 , the fire water filling valve includes a water outlet pipe 1, a valve cover 2 and a locking mechanism 101.

[0052] Water outlet pipe 1 is connected to the outlet end of the aforementioned fire-fighting pipeline.

[0053] Valve cover 2 covers the outlet 10 of water pipe 1, and the valve cover 2 is pivotally connected to the outlet 10 of water pipe 1.

[0054] The locking mechanism 101 includes a lever 3, an elastic element 4, and a temperature-sensitive glass tube 5. The lever 3 is located on the outer periphery of the water outlet pipe 1. One end of the lever 3 is connected to the elastic element 4 and the temperature-sensitive glass tube 5, and the other end of the lever 3 is provided with a hook part 31.

[0055] The elastic element 4 and the temperature-sensitive glass tube 5 are disposed between the outer wall of the water outlet pipe 1 and one end of the lever 3, so that the other end of the lever 3 abuts against the pipe opening 10 of the water outlet pipe 1, thereby causing the hook part 31 on the other end of the lever 3 to fasten onto the valve cover 2, thereby locking the valve cover 2 that is covered on the pipe opening 10 of the water outlet pipe 1.

[0056] Compared with the prior art, the fire-fighting water valve provided in this application embodiment changes the traditional fire-fighting water valve structure with temperature-sensitive glass tube 5. The temperature-sensitive glass tube 5 is no longer used as a component to block the water outlet, so that the size of the pipe opening 10 of the water outlet pipe 1 is not limited.

[0057] Specifically, such as Figure 2 As shown, the fire-fighting water filling valve of this application includes a valve cover 2 installed on the outlet 10 of the water pipe 1 and its locking mechanism 101. The locking mechanism 101 includes a lever 3, an elastic element 4, and a temperature-sensitive glass tube 5 disposed outside the outlet 10 of the water pipe 1. The temperature-sensitive glass tube 5 is disposed as a supporting element between one end of the lever 3 and the outer wall of the outlet 1, so that the elastic element 4 is in an expanded state, and at the same time, the other end of the lever 3 abuts against the outlet 10 of the water pipe 1, so that the hook portion 31 on the other end of the lever 3 is fastened to the valve cover 2, and the valve cover 2 tightly closes the outlet 10 of the water pipe 1. The elastic element 4 here can preferably be a tension spring.

[0058] When the temperature-sensitive glass tube 5 breaks due to heat, such as Figure 3 As shown, due to the lack of support from the temperature-sensing glass tube 5, the elastic element 4 will contract and return to its original state, causing one end of the lever 3 connected to the elastic element 4 to abut against the outer wall of the water outlet pipe 1. At the same time, the hook part 31 on the other end of the lever 3 will move away from the valve cover 2, thereby releasing the latch on the valve cover 2. The valve cover 2 is directly pushed open by the water flow in the water outlet pipe 1 in an unlocked state, thus realizing water outlet.

[0059] Therefore, the fire water filling valve of the present application is not limited by the blocking volume and the structural strength of the temperature sensing glass tube 5, and the pipe opening 10 of the water outlet pipe 1 can be increased according to the use requirement, as long as the cover area of the valve cover 2 can match the size of the pipe opening 10. The locking mechanism 101 is arranged outside the pipe opening 10 of the water outlet pipe 1, and the valve cover 2 is locked and fixed by the lever 3 and the components thereon, so that the locking strength is effectively ensured, which is beneficial to withstand a larger water pressure, and further increases the water outlet capacity of the entire fire water filling valve.

[0060] In addition, compared with the water valve structure in the prior art which uses a solenoid valve as a control valve to open and close, the fire water filling valve of the present application is a pure mechanical structure, does not need to be connected with a control line, and does not need to be controlled online, so that the problem that the system is paralyzed and cannot independently detect a fire alarm and cannot timely open the valve for fire extinguishing is effectively avoided when the system fails or the control line is damaged. The fire water filling valve with a pure mechanical structure keeps the water outlet valve in a state that can be triggered to open, so that the working stability and reliability of the fire extinguishing equipment are effectively ensured.

[0061] In an embodiment of the present application, please refer to Figure 4 and Figure 4 , the water outlet pipe 1 is provided with a first connecting lug 11 and a second connecting lug 12, and the first connecting lug 11 and the second connecting lug 12 are arranged on opposite sides of the pipe opening 10 of the water outlet pipe 1. The middle part of the lever 3 has a supporting part 32, and the supporting part 32 is connected with the first connecting lug 11 through a rotating shaft. The side part of the valve cover 2 is connected with the second connecting lug 12 through a rotating shaft. In this way, the valve cover 2 can be rotated to open or close the pipe opening 10 on one side of the pipe opening 10 of the water outlet pipe 1. The lever 3 is arranged on the other side of the pipe opening 10 of the water outlet pipe 1 to rotate the lever 3, so that the hook part 31 on the lever 3 can be buckled on the valve cover 2 which closes the pipe opening 10 to lock and fix the valve cover 2.

[0062] Please refer to Figure 5 and Figure 4 , on the lever 3 of the fire water filling valve of the present application, the supporting part 32 to one end of the lever 3 includes a slanted plate 33 and a straight plate 34 connected with each other in sequence, and the temperature sensing glass tube 5 and the elastic member 4 are supported between the straight plate 34 and the outer wall of the water outlet pipe 1, so that the supporting part 32 to the other end of the lever 3 abuts against the pipe opening 10 of the water outlet pipe 1, and thus the hook part 31 on the other end of the lever 3 is buckled on the cover.

[0063] In this way, the inclined plate 33 and the straight plate 34 on the lever 3 form a space for arranging the temperature sensing glass tube 5 outside the outer wall of the outlet pipe 1, and also form a space for the elastic member 4 to deform and drive the one end of the lever 3 to move. The temperature sensing glass tube 5 is supported between the outer wall of the outlet pipe 1 and the straight plate 34, so that the other end of the lever 3 abuts against the pipe opening 10 of the outlet pipe 1, and at the same time, the hook part 31 on the other end of the lever 3 is buckled on the valve cover 2. The elastic member 4 can preferably be a tension spring, which extends between the outer wall of the outlet pipe 1 and the straight plate 34 to keep the two in soft connection.

[0064] When a fire alarm occurs, the temperature sensing glass tube 5 is broken by heat, so that the support between the outer wall of the outlet pipe 1 and the straight plate 34 disappears, the elastic member 4 automatically contracts and restores, drives the straight plate 34 to abut against the outer wall of the outlet pipe 1, and at the same time, the hook part 31 on the other end of the lever 3 is removed from the valve cover 2, thereby releasing the locking of the valve cover 2.

[0065] It can be seen that the locking mechanism 101 is a structure of pure mechanical components cooperating, without the need for online control to trigger the unlocking operation, effectively ensuring the triggering stability of the locking mechanism 101.

[0066] For the mounting structure of the temperature sensing glass tube 5, in an embodiment of the present application, please refer to Figure 5 and Figure 4 , the outer wall of the outlet pipe 1 is provided with a mounting groove 13, and the lever 3 is provided with a positioning groove 35 corresponding in position to the mounting groove 13. In this embodiment, the positioning groove 35 can be preferably formed in the straight plate 34 described above. The temperature sensing glass tube 5 preferably adopts a fire-fighting glass tube body that breaks by sensing temperature, and the two ends of the temperature sensing glass tube 5 are respectively embedded in the mounting groove 13 and the positioning groove 35 described above, so that the temperature sensing glass tube 5 is fixed between the outer wall of the outlet pipe 1 and the lever 3. It can be seen that the mounting structure of the temperature sensing glass tube 5 is very simple, when replacing a new temperature sensing glass tube 5, the two ends of the temperature sensing glass tube 5 can be directly inserted into the mounting groove 13 of the outer wall of the outlet pipe 1 and the positioning groove 35 on the lever 3, which is convenient for installation and effectively improves the installation efficiency.

[0067] For the mounting structure of the elastic member 4, in an embodiment of the present application, as shown in Figure 5 and Figure 6 , the elastic member 4 can preferably be a tension spring, and the two ends of the tension spring have hooks, and the outer wall of the outlet pipe 1 and the lever 3 are provided with a first clamping ear 14 and a second clamping ear 36 corresponding in position, so that the two ends of the tension spring are respectively buckled and fixed.

[0068] For the structure of the valve cover 2, in actual application, the water pressure in the fire-fighting pipeline is unstable, especially when the fire-fighting filling valve is arranged at the top of the fire-fighting environment, so that the pipe opening 10 of the outlet pipe 1 is arranged downward. In this arrangement, if the valve cover 2 cannot be opened and moved away from the downward projection range of the pipe opening 10 as much as possible, the water flow output will be easily blocked, and the outlet water pressure and direction will be affected.

[0069] Therefore, in one embodiment of the present application, referring to Figure 7 and Figure 7 , a counterweight 21 is arranged on the valve cover 2, which is arranged close to the side of the valve cover 2 where the second connecting lug 12 is located. Specifically, as shown in Figure 6 , it can be on the straight line distance L between the center point P1 of the valve cover 2 and the edge P2 where the valve cover 2 is connected to the second connecting lug 12. Further, it can be on the midpoint of the aforementioned straight line distance L. In this way, the center of gravity of the valve cover 2 can be offset to the direction of the shaft connecting part of the valve cover 2 and the pipe opening 10 of the outlet pipe 1, so that the valve cover 2 can naturally rotate open to that side in the unlocked state, effectively reducing the blockage of the water outlet.

[0070] Referring to Figure 7 , Figure 8 and Figure 6 , the valve cover 2 further comprises a connecting rod 22 connected to the aforementioned counterweight 21, which is arranged on the valve cover 2 and extends into the outlet pipe 1 or extends in a direction away from the pipe opening 10 of the outlet pipe 1, and the aforementioned counterweight 21 is arranged on the extension end of the connecting rod 22. In this way, the counterweight 21 is supported on the valve cover 2 by the connecting rod 22 and away from the surface of the valve cover 2, so that the center of gravity is offset from the valve cover 2 to outside the valve cover 2. It is equivalent to arranging a power outside the valve cover 2 to exert a pushing force or a pulling force on the valve cover 2, so that the valve cover 2 rotates open around the shaft connecting part as the axis, thereby further increasing the opening amplitude of the valve cover 2 and moving away from the downward projection range of the pipe opening 10 of the outlet pipe 1 to reduce the blockage of the water outlet.

[0071] In this embodiment, as shown in Figure 8 , the counterweight 21 can preferably have a spherical structure to reduce the blocking area of the water flow. The connecting rod 22 is arranged on the inner wall surface of the valve cover 2, which can be vertically arranged or obliquely arranged, as long as the counterweight 21 is supported on the valve cover 2 and arranged close to the side of the valve cover 2 where the second connecting lug 12 is located. When the locking mechanism 101 releases the locking of the valve cover 2, the counterweight 21 arranged in the above manner can exert a pushing force on the valve cover 2 closed on the pipe opening 10 to naturally open the valve cover 2. This arrangement is beneficial to the downward arrangement of the pipe opening 10 of the outlet pipe 1, and the valve cover 2 naturally opens downward and flips to the side of the pipe opening 10, moving away from the downward projection range of the pipe opening 10 of the outlet pipe 1 to reduce the blockage of the water flow.

[0072] In other embodiments (not shown), the connecting rod 22 can also be arranged on the outer wall surface of the valve cover 2, i.e. on the wall surface of the valve cover 2 facing away from the pipe opening 10 of the water outlet pipe 1, so that the counterweight 21 is supported outside the entire valve body. When the locking mechanism 101 releases the locking of the valve cover 2, the counterweight 21 exerts a pulling force on the valve cover 2 outside the water outlet pipe 1, naturally pulling the valve cover 2 apart. In this arrangement, the pipe opening 10 of the water outlet pipe 1 can be arranged downwardly or horizontally, which is also applicable. When the pipe opening 10 of the water outlet pipe 1 is arranged horizontally, as shown in Figure 8 , it is preferable to arrange the valve cover 2 and the shaft connecting portion (i.e. the second connecting lug 12) of the water outlet pipe 1 on the side of the pipe opening 10 of the water outlet pipe 1 close to the ground, so that the valve cover 2 can naturally spread downward after being opened, thereby avoiding blocking the water flow.

[0073] For the opening structure of the valve cover 2 described above, in another embodiment of the present application (not shown), a torsion spring (not shown) is arranged at the shaft connecting portion of the valve cover 2 and the second connecting lug 12. The action force of the torsion spring enables the valve cover 2 to be rotated as far as possible outside the pipe opening 10 of the water outlet pipe 1, so that the valve cover 2 moves out of the downward projection range of the pipe opening 10 of the water outlet pipe 1, thereby also reducing the blocking of the water outlet.

[0074] For the structure of the valve cover 2, in one embodiment of the present application, please refer to Figure 9 and Figure 9 , the valve cover 2 further comprises a sealing ring 23 and a protruding ring 24 for being embedded in the pipe opening 10 of the water outlet pipe 1, and the sealing ring 23 is sleeved on the protruding ring 24. In this way, when the valve cover 2 is closed on the pipe opening 10 of the water outlet pipe 1, the sealing ring 23 is tightly pressed against the pipe opening 10 of the water outlet pipe 1, thereby improving the sealing effect.

[0075] Preferably, as shown in Figure 4 , the inner ring of the sealing ring 23 has a folded edge 231 matched with the shape of the protruding ring 24 on the valve cover 2, so that when the sealing ring 23 is arranged on the pipe opening 10 of the water outlet pipe 1, the folded edge 231 is folded along the edge of the pipe opening 10 and embedded inside the water outlet pipe 1, effectively preventing the sealing ring 23 from being easily displaced, thereby improving the sealing effect and the fixing effect of the sealing ring 23.

[0076] For the structure of the clamping portion of the lever 3 and the valve cover 2, in one embodiment of the present application, please refer to Figure 10 and Figure 10 , the clamping hook portion 31 of the lever 3 is provided with a roller 311, and the rotation of the roller 311 is conducive to improving the smoothness of the clamping or separation of the clamping hook portion 31, thereby avoiding the clamping hook portion 31 from being stuck and affecting the timely opening of the valve cover 2, thereby improving the sensitivity of the opening of the valve cover 2.

[0077] The valve cover 2 is provided with a frame 25 composed of three edge ribs 251, and a clamping groove 252 is formed in the frame 25 for embedding the roller 311, so as to define the movement path of the roller 311 and improve the guiding effect of the roller 311. The roller 311 is quickly moved away from the valve cover 2, and the locking of the valve cover 2 is released.

[0078] As shown in Figure 6 , the middle rib 251 of the three edge ribs 251 is provided with two opposite inclined surfaces 253. In this way, the two edge ribs 251 on both sides of the frame 25 limit the movement path of the roller 311 from both sides, and the middle rib 251 functions to clamp the roller 311. The two opposite inclined surfaces 253 on the middle rib 251 facilitate the clamping and disengaging of the roller 311 in and from the frame 25.

[0079] In another embodiment of the present application (not shown), the hook portion 31 of the lever 3 is provided with a roller 311, and the valve cover 2 is provided with a limiting groove (not shown) for embedding the roller 311. In this way, the rotation of the roller 311 improves the smoothness of the clamping and disengaging of the hook portion 31, thereby improving the sensitivity of opening the valve cover 2.

[0080] When the hook portion 31 is clamped on the cover, the roller 311 can be embedded in the limiting groove of the valve cover 2 to clamp the hook portion 31 on the valve cover 2. When the locking mechanism 101 unlocks the valve cover 2, the roller 311 can slide out of the limiting groove, so that the entire hook portion 31 is smoothly removed from the valve cover 2 to avoid jamming, thereby improving the sensitivity of unlocking and allowing the valve cover 2 to be opened in time.

[0081] In one embodiment of the present application, please refer to Figure 8 and Figure 11 , the water outlet pipe 1 is further provided with a pressure sensor 6 located inside the water outlet pipe 1 to detect the water pressure inside the water outlet pipe 1. When the locking mechanism 101 triggers to open the valve cover 2, the water pressure in the water outlet pipe 1 changes, and the pressure sensor 6 generates a detection signal to timely trigger the corresponding alarm application.

[0082] For the internal fire-fighting pipeline arrangement of the entire energy storage device, in one embodiment of the present application, please refer to Figure 12 and Figure 6 , the energy storage device includes a container body 200, the container body 200 has a plurality of receiving cavities 201 for placing battery modules, and the container body 200 is provided with a fire-fighting pipeline 300 and the fire-fighting irrigation valve 100 of the present application. The fire-fighting pipeline 300 extends into each receiving cavity 201, and the water outlet end of each fire-fighting pipeline 300 is provided with the fire-fighting irrigation valve 100 of the present application.
