Description

Technical Field

[0001] This utility model relates to the field of fire protection technology for energy storage containers, and in particular to a fixing device for fire extinguishing gas cylinders in energy storage containers. Background Technology

[0002] With the rapid development of the energy storage industry, megawatt-level containerized energy storage systems are increasingly widely used in power grids, playing a crucial supporting role in improving the stability, reliability, and power quality of power systems. Against this backdrop, the safety of lithium batteries has become a major concern, and fire suppression systems have become an indispensable subsystem in containerized energy storage systems. These fire suppression systems mainly consist of detection and extinguishing systems. The extinguishing systems often employ gaseous extinguishing agents such as perfluorohexanone or heptafluoropropane, with the extinguishing agents stored in fire-extinguishing cylinders, which are then securely installed inside the container.

[0003] Currently, the common method for securing fire extinguishing gas cylinders involves using double-walled steel straps and bolts for a tight grip. However, in practical applications, this method has been found to have drawbacks. Because the steel straps themselves have a certain degree of deflection, they are prone to deformation under horizontal stress, causing displacement of the gas cylinders. This is particularly problematic during container road tests or long-distance transport to project sites, where the cylinders' movement can easily damage precision electronic components such as solenoid valves and pressure gauges, posing a safety hazard. Therefore, it is necessary to improve the existing gas cylinder securing structure to enhance its rigidity and stability. Utility Model Content

[0004] In view of this, this utility model proposes a fixing device for fire extinguishing gas cylinders in energy storage containers to solve the problem that the existing technology causes the gas cylinders to be not firmly fixed due to the deflection of the steel belt, and the cylinders are easy to move in the horizontal direction, which damages the precision components on them.

[0005] The technical solution of this utility model is implemented as follows: This utility model provides a device for fixing fire-fighting gas cylinders in an energy storage container, comprising: The first clamp is used to fix the container wall; The second clamp is arranged opposite to the first clamp and is used to jointly clamp the fire extinguishing gas cylinder with the first clamp. Two connecting rods are arranged in parallel between the first clamp and the second clamp, with one end of each connecting rod connected to the first clamp and the other end passing through the second clamp; A fastening structure is provided at one end of each of the connecting rods that passes through the second clamp, for driving the second clamp to move along the connecting rod to adjust and lock the relative distance between the first clamp and the second clamp.

[0006] Based on the above technical solution, preferably, the first clamp and the second clamp are each provided with a recessed clamping part on opposite sides.

[0007] Based on the above technical solution, preferably, the clamping part is an arc-shaped concave surface or a V-shaped structure.

[0008] Based on the above technical solution, preferably, the first clamp has at least two mounting holes for fixed connection with the container wall by fasteners.

[0009] Based on the above technical solution, preferably, the connecting rod is a lead screw, and the fastening structure includes a nut that is threadedly engaged with the lead screw.

[0010] Based on the above technical solution, preferably, the second clamp has through holes at both ends for the connecting rod to pass through, and the nut has an annular flange at the end facing the second clamp. The nut fits against the outer surface of the second clamp through its annular flange, and the threaded hole of the nut is coaxially corresponding to the through hole. The fastening structure also includes a limiting member, which is disposed on the side of the annular flange facing away from the second clamp, for limiting the movement of the nut along the axial direction of the through hole, while allowing the nut to rotate.

[0011] Based on the above technical solution, preferably, the limiting member includes a limiting post and a limiting disc coaxially connected to the limiting post; one end of the limiting post is connected to the outer surface of the second clamp, and its outer wall is tangent to or adjacent to the edge of the annular flange; the outer diameter of the limiting disc is larger than the outer diameter of the limiting post and fits against the end face of the annular flange; there are multiple limiting members, and the multiple limiting members are arranged around the axis of the nut to jointly restrict the annular flange.

[0012] Based on the above technical solution, preferably, the end of the limiting post away from the limiting plate is fixedly or rotatably connected to the outer surface of the second clamp.

[0013] Based on the above technical solution, preferably, one end of the connecting rod is connected to the first clamp hinge.

[0014] Based on the above technical solution, preferably, the two connecting rods are located on both sides of the clamping part.

[0015] The present invention has the following advantages over the prior art: (1) The energy storage container fire-fighting gas cylinder fixing device disclosed in this utility model constructs a high-rigidity overall frame through the coordinated cooperation of the first clamp, the second clamp, the connecting rod and the fastening structure. This device can effectively constrain the displacement of the gas cylinder in all directions, especially significantly improving the constraint stiffness in the horizontal direction, fundamentally eliminating the risk of damage to the precision components on the gas cylinder due to shaking, and also has the advantages of convenient adjustment and wide adaptability.

[0016] (2) By setting a combination structure of annular flange and limiting component, the nut is rotatably restricted to the second clamp.

[0027] like Figure 1 As shown, combined with Figure 2-5 This utility model embodiment discloses a fixing device for fire-fighting gas cylinders in an energy storage container, including a first clamp 1, a second clamp 2, two connecting rods 3 and a fastening structure 4.

[0028] The first clamp 1 serves as the fixing foundation for the entire device and is configured to be firmly installed on the wall of the container. The first clamp 1 can be fixed to the wall by means of welding or bolting, thereby providing a stable and reliable support point for its subsequent components.

[0029] The second clamp 2 is positioned opposite the first clamp 1. The second clamp 2 and the first clamp 1 work together to form a clamping space for accommodating and securing the fire extinguishing gas cylinder P. The second clamp 2 is movable, and its position can be adjusted according to the outer diameter of the gas cylinder, thereby adapting to different specifications of gas cylinders and achieving a universal fixing function.

[0030] Two connecting rods 3 are arranged parallel to each other between the first clamp 1 and the second clamp 2. One end of each connecting rod 3 is connected to the first clamp 1, and the other end passes through a corresponding hole on the second clamp 2. These connecting rods 3 not only connect the first clamp 1 and the second clamp 2, but more importantly, they provide precise guidance for the movement of the second clamp 2. By ensuring the parallelism of the connecting rods 3, the second clamp 2 can be guaranteed to maintain a parallel relationship with the first clamp 1 during movement, thereby ensuring that the gas cylinder is evenly clamped and avoiding additional stress caused by uneven force.

[0031] A fastening structure 4 is installed at one end of each connecting rod 3 that passes through the second clamp 2. This fastening structure 4 is a key component for distance adjustment and locking. Its basic function is to act on the second clamp 2, driving it to move axially along the connecting rod 3. When a force is applied to the fastening structure 4, the second clamp 2 can be pushed closer to the first clamp 1, thereby reducing the clamping space to tighten the gas cylinder; when it is necessary to disassemble or replace the gas cylinder, loosening the fastening structure 4 will allow the second clamp 2 to move away from the first clamp 1, expanding the operating space. After reaching the preset clamping force, the fastening structure 4 can reliably lock the position of the second clamp 2, ensuring that the relative distance between the first clamp 1 and the second clamp 2 remains unchanged under conditions such as vibration and impact.

[0032] The energy storage container fire-fighting gas cylinder fixing device disclosed in this utility model constructs a high-rigidity overall frame through the coordinated cooperation of the first clamp 1, the second clamp 2, the connecting rod 3, and the fastening structure 4. This device can effectively restrain the displacement of the gas cylinder in all directions, especially significantly improving the restraint stiffness in the horizontal direction, fundamentally eliminating the risk of damage to the precision components on the gas cylinder due to shaking, while also having the advantages of convenient adjustment and wide adaptability.

[0033] In some embodiments, the first clamp 1 and the second clamp 2 are each provided with a recessed clamping portion G on their opposite sides.

[0034] The recessed design of the clamping part G allows it to better conform to the cylindrical outer wall of the fire extinguishing gas cylinder P. Compared to a flat clamping surface, the recessed clamping part G significantly increases the actual contact area between the clamp and the cylinder shell. This increased contact area means that pressure is dispersed, effectively reducing potential localized stress concentration on the cylinder wall under clamping force and avoiding potential surface damage caused by point or line contact.

[0035] In addition, the clamping part G also serves as a preliminary positioning element. When placing the gas cylinder, its cylindrical outer shell naturally fits into the recesses of the two side clamps. This helps to keep the gas cylinder roughly centered before the fastening structure 4 is fully tightened, facilitating subsequent installation and adjustment operations.

[0036] In some embodiments, the clamping part G is an arc-shaped concave surface or a V-shaped structure.

[0037] The concave arc surface is a shape that perfectly matches the cylindrical outer wall of the fire extinguishing gas cylinder. Its radius of curvature can be matched with the outer diameter of the cylinder, thus forming a large-area, uniform line or surface contact when clamped. This contact method can evenly distribute the clamping force across the entire circumferential contact area of ​​the cylinder's outer wall, minimizing the risk of localized stress concentration and providing a stable and gentle constraint for the cylinder.

[0038] The V-shaped structure offers a more adaptable clamping solution. Its two beveled sides form an angle, allowing the outer wall of the cylinder to contact the beveled surface of the V-shaped structure when the clamp grips cylinders of different diameters. The V-shaped structure can adaptively adjust the position of the contact line within a certain diameter range. Although the contact area may not be as large as a perfectly matched concave arc, it provides excellent centering and positioning during clamping and is potentially simpler to manufacture.

[0039] Whether it's a curved concave surface or a V-shaped structure, their inward concavity serves a common core purpose: to transform potential point contact into line contact or a more optimized surface contact. This optimized shape design directly improves the efficiency and safety of force transmission between the clamp and the gas cylinder.

[0040] In some embodiments, the first clamp 1 has at least two mounting holes 11 for fixed connection with the container wall by fasteners.

[0041] Specifically, fasteners, such as bolts or screws, pass through these mounting holes 11 and are screwed into pre-drilled threaded holes in the wall or engage with nuts 41. This connection method forms a rigid fixed node. When the weight of the gas cylinder and the inertial forces generated during transportation are transmitted to the first clamp 1 through the device, these forces are shared by the fasteners at the multiple mounting holes 11, thereby significantly improving the connection rigidity and reliability between the first clamp 1 and the housing, and effectively suppressing possible minor displacements or shaking.

[0042] The use of mounting holes 11 and fasteners also brings convenience to installation and maintenance. During installation, the final position of the first clamp 1 on the wall can be precisely adjusted before final tightening. When the clamp needs to be replaced or repaired, it can be removed simply by loosening the fasteners, which is easy to operate and avoids the inconvenience of permanent connections such as welding.

[0043] In some embodiments, the connecting rod 3 is a lead screw, and the fastening structure 4 includes a nut 41 that is threadedly engaged with the lead screw.

[0044] The internal thread on nut 41 meshes with the external thread of the lead screw, forming a threaded pair. Nut 41 constitutes the locking part of fastening structure 4. When the operator tightens nut 41, nut 41 will move axially along the lead screw. Since the connection between one end of the lead screw and the first clamp 1 is fixed, and nut 41 acts on the second clamp 2, the movement of nut 41 will be directly converted into the power to drive the second clamp 2 to move closer to or away from the first clamp 1 along the axis of the lead screw.

[0045] When it is necessary to disassemble the gas cylinder, the nut 41 needs to be removed from the second clamp 2. At this time, the nut 41 is easily lost when not in operation. Therefore, this embodiment adopts the following technical solution to solve the problem.

[0046] Specifically, in this embodiment, the second clamp 2 has through holes 21 machined at both ends, through which the lead screw passes. The inner diameter of the through hole 21 is slightly larger than the outer diameter of the lead screw, providing the necessary clearance for the lead screw to pass through, and also playing a certain guiding role.

[0047] The end of the nut 41 facing the second clamp 2 has an integrally formed annular flange 410. The outer diameter of the annular flange 410 is larger than the outer diameter of the nut 41 body. During assembly, the nut 41 fits against the outer surface of the second clamp 2 through its annular flange 410, and the threaded hole of the nut 41 is coaxially aligned with the through hole 21 on the second clamp 2, thereby ensuring that the lead screw can be smoothly screwed into the nut 41.

[0048] A limiting member 42 is disposed on the side of the annular flange 410 facing away from the second clamp 2. The main function of the limiting member 42 is to restrict the nut 41 from moving axially away from the second clamp 2 along the through hole 21. Through axial limiting, the nut 41 is constrained on the second clamp 2 and cannot fall off from the through hole 21, thus becoming an integrated component associated with the second clamp 2.

[0049] Although the limiting member 42 restricts the axial movement of the nut 41, it does not prevent the nut 41 from rotating around its own axis. When using a tool to tighten the nut 41, the nut 41 can still rotate freely. The rotation of the nut 41 will drive it to produce axial displacement along the fixed lead screw, but due to the presence of the limiting member 42, this axial displacement is converted into a pushing and pulling action on the second clamp 2, thereby realizing the adjustment function of tightening or loosening the gas cylinder.

[0050] By setting up a combination structure of annular flange 410 and limiting member 42, nut 41 is rotatably restrained on second clamp 2. This design not only prevents nut 41 from being accidentally lost when not in operation, but also fully retains its core function of linear adjustment by rotation, greatly improving the ease of operation of the fixing device and the integration of components.

[0051] This embodiment illustrates one structural configuration of the limiting member 42. Specifically, the limiting member 42 includes a limiting post 421 and a limiting disk 422 coaxially connected to the limiting post 421.

[0052] One end of the limiting post 421 is connected to the outer surface of the second clamp 2, thereby fixing the entire limiting member 42 onto the second clamp 2. The axial direction of the limiting post 421 is approximately parallel to the axis of the nut 41, and the position of its outer wall is set to be tangent to or very close to the edge of the annular flange 410 on the nut 41. This close spacing allows the side wall of the limiting post 421 to form a radial barrier against the edge of the annular flange 410, effectively limiting any possible shaking or displacement of the nut 41 in the radial plane, thus playing a radial limiting role.

[0053] The limiting disc 422, coaxially connected to the limiting post 421, has an outer diameter larger than that of the limiting post 421. The limiting disc 422 fits against the end face of the annular flange 410 facing away from the second clamp 2. Because the limiting disc 422 has a larger diameter, it acts like a cover, with its inner end face covering the outer end of the annular flange 410, thereby axially blocking the movement path of the annular flange 410 (along with the entire nut 41) away from the second clamp 2, achieving reliable axial limiting and preventing the nut 41 from falling off.

[0054] Each limiting element 42 primarily provides unidirectional limiting. To achieve stable and balanced circumferential constraint on the nut 41, this embodiment limits the number of limiting elements 42 to multiple, and these limiting elements 42 are arranged uniformly or symmetrically around the axis of the nut 41. Multiple limiting elements 42 act together from different directions, like a surrounding ring, firmly restricting the annular flange 410 of the nut 41 in a preset position. This multi-point coordinated constraint ensures that the nut 41 does not wobble during rotation, operates smoothly, and can withstand forces from all directions, enhancing overall reliability.

[0055] In some embodiments, the number of limiting members 42 is at least three, for example, three limiting members 42 are arranged at equal intervals around the axis of nut 41.

[0056] By employing a specific limiting element 42 structure composed of limiting posts 421 and limiting discs 422, and using a scheme in which multiple limiting elements 42 are arranged around each other, an optimized design combining radial and axial limiting and multi-point collaborative constraint is provided. This design securely restrains the nut 41 on the second clamp 2, allowing only the intended rotation and preventing axial movement, detachment, or shaking, significantly improving the integrity and operational reliability of the assembly.

[0057] In some embodiments, one end of the limiting post 421 away from the limiting disc 422 is fixedly or rotatably connected to the outer surface of the second clamp 2.

[0058] In this configuration, when the end of the limiting post 421 furthest from the limiting disc 422 is fixedly connected to the second clamp 2, the entire limiting component 42 and the second clamp 2 form a relatively static rigid whole. In this configuration, when the operator rotates the nut 41, the end face of the annular flange 410 on the nut 41 will experience sliding friction relative to the inner surface of the stationary limiting disc 422. Simultaneously, there may also be sliding or contact between the outer circumferential edge of the annular flange 410 and the inner wall of the stationary limiting post 421. This scheme provides a stable structure, a relatively simple manufacturing process, and a solid constraint foundation for the nut 41.

[0059] When the end of the limiting post 421 furthest from the limiting plate 422 is rotatably connected to the second clamp 2, the limiting member 42 itself gains the freedom to rotate about its axis. In this configuration, when the nut 41 is tightened, the static friction between the end face of the annular flange 410 and the inner surface of the limiting plate 422 drives the limiting member 42 to rotate along with the nut 41. This means that the critical contact interface (between the end face of the annular flange 410 and the limiting plate 422) changes from sliding friction to approximately synchronous rolling friction, or at least a friction state with significantly reduced relative speed. This change in motion effectively reduces frictional resistance and wear on the contact surface, making the tightening of the nut 41 easier and smoother, thus improving the adjustment feel and the long-term service life of the component.

[0060] In some embodiments, one end of the connecting rod 3 is hinged to the first clamp 1. This configuration creates a rotatable connection between one end of the connecting rod 3 and the first clamp 1, allowing the connecting rod 3 to swing relative to the first clamp 1 within a certain angular range.

[0061] When it is necessary to place or remove the fire extinguishing gas cylinder P, the fastening structure 4 can be loosened first to disengage the second clamp 2 and the connecting rod 3. At this time, since the connecting rod 3 is hinged to the first clamp 1, the operator can swing the connecting rod 3 towards the container wall, so that the connecting rod 3 is close to the container wall. The swinging of the connecting rod 3 frees up horizontal space in front of the first clamp 1. The freeing up of the connecting rod 3 allows the fire extinguishing gas cylinder P to be moved horizontally and unobstructed into or out of the installation area defined by the first clamp 1. This solves the problem of requiring a horizontal movement path for the installation and removal of gas cylinders in the confined space of a container.

[0062] After the gas cylinder is in place at the first clamp 1, swing the connecting rod 3 back to the working position so that its free end passes through the corresponding through hole 21 on the second clamp 2 again. Finally, lock the second clamp 2 and the connecting rod 3 together with the fastening structure 4 to restore the complete fixed frame.

[0063] The hinged connection allows the connecting rod 3 to swing independently, cleverly clearing horizontal obstacles by temporarily removing it. This structural design significantly optimizes the installation and disassembly process of the gas cylinder, making it particularly suitable for space-constrained working environments. While ensuring the final rigidity of the fixed frame, it greatly improves operational convenience.

[0064] In some embodiments, the two connecting rods 3 are located on both sides of the clamping portion G. Therefore, the point of force applied by the connecting rods 3 is located at the outer edge of the clamping area. This arrangement allows the first clamping clamp 1 and the second clamping clamp 2 to apply a clamping force symmetrically to the gas cylinder via the connecting rods 3 located on both sides of the clamping portion G.

[0065] When the fastening structure 4 is tightened, the force is evenly transmitted to the first clamp 1 and the second clamp 2 through the connecting rods 3 on both sides. The connecting rods 3 located on both sides of the clamping part G act as two symmetrical force application points, ensuring that the clamping force is evenly distributed across the entire contact surface between the gas cylinder and the clamp. This symmetrical force distribution mode can avoid the possibility of slight torsion of the gas cylinder or clamp or excessive stress on one side due to the offset of the force application point.

[0066] In addition, the symmetrically arranged connecting rods 3 and the clamps together form a stable frame structure. This structure can more effectively resist inertial forces or impact forces from different directions, preventing unnecessary shaking or displacement of the gas cylinder within the fixing device, thereby enhancing the reliability and stability of the entire fixing device under dynamic operating conditions.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
