Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the application of energy storage fire extinguishing devices, the design of the mounting rack clamping mechanism directly affects the safety and operational efficiency of the equipment. In existing technologies, various types of clamping structures have been developed to meet the fixing needs of fire extinguishing devices in different scenarios. Their core objective is to achieve rapid installation, stable fixation, and convenient access. These mechanisms are typically designed specifically for the usage environment, the size and weight of the fire extinguishing device, and range from basic mechanical structures to semi-automated systems.

[0031] Common clamping mechanisms can be categorized into three main types based on their installation method: wall-mounted, floor-standing, and embedded. Wall-mounted structures typically combine a metal frame with adjustable clamps, fixed to the wall using pre-embedded bolts or expansion screws. They are suitable for indoor environments with limited space, such as computer rooms and power distribution rooms. Their advantage lies in utilizing vertical space and reducing floor space occupation, but they are limited by the wall's load-bearing capacity and are generally suitable for small to medium-sized fire extinguishing devices. Floor-standing structures achieve self-support through a combination of a base and support legs, often equipped with anti-slip pads or fixing holes at the bottom. They are suitable for outdoor energy storage sites or mobile fire extinguishing equipment storage. Their advantages include high stability and ease of adjustment, but they are larger and have lower mobility. Embedded designs are commonly found inside customized cabinets or containers, where the clamping mechanism is integrated with the container structure. The fire extinguishing device is fixed using slide rails, slots, or modular interfaces, and they are commonly found in scenarios requiring integrated management, such as lithium battery energy storage containers.

[0032] From the perspective of clamping principles, existing technologies mainly employ three methods: mechanical locking, elastic pressing, and linkage mechanisms. Mechanical locking structures use bolts, knobs, or levers as the main operating components. For example, rotating a handle drives a screw to advance the clamping plate, utilizing the self-locking property of the threads to achieve fixation. These structures have high load-bearing capacity, but involve numerous operating steps, resulting in lower efficiency, especially in scenarios requiring frequent loading and unloading. Elastic pressing mechanisms generate clamping force through the deformation of springs, rubber pads, or shape-memory metals, such as V-shaped spring clips or annular elastic rings. Their advantage lies in adapting to a certain range of dimensional changes without manual adjustment, but they require a high degree of surface flatness in the fire extinguishing device and are prone to elastic decay after long-term use. Linkage mechanisms achieve multi-point synchronous action through linkages, gears, or pulley systems. For example, a four-bar linkage synchronous clamping system can simultaneously tighten multiple clamping arms when force is applied at a single point, improving operational convenience. However, their structural complexity is high, leading to increased maintenance costs.

[0033] In terms of material selection, existing clamping mechanisms mostly employ composite structures of metal and polymer materials. The main frame often uses galvanized steel plates, aluminum alloys, or stainless steel to ensure sufficient mechanical strength and corrosion resistance. Stainless steel is particularly prevalent in corrosive environments such as coastal areas or chemical plants. Clamping contact surfaces are often covered with rubber, silicone, or polyurethane materials. For example, anti-slip textures or cushioning pads are added to curved clamps to increase the coefficient of friction, prevent slippage, and avoid scratches caused by direct metal contact with the fire extinguishing device surface. In recent years, some high-end products have begun to introduce engineering plastics as the main material, achieving lightweight design through injection molding. However, their load-bearing capacity is usually limited to below 15 kg, suitable for storing small fire extinguishers.

[0034] Regarding improvements in ease of operation, existing technologies have yielded several solutions. For example, quick-release buckle designs allow for release by pressing a release button; magnetic-assisted positioning is another option, embedding permanent magnets inside the clamping plate to automatically attract and align the fire extinguishing device when it approaches. Some products also integrate casters and brakes into the support legs for easier movement of the fire extinguishing unit in storage environments. However, these designs often require a trade-off between stability and convenience. For instance, structures with casters may pose a risk of accidental displacement in vibrating environments, necessitating additional locking mechanisms.

[0035] Existing clamping mechanisms exhibit varying degrees of adaptability in their design for fire extinguishing devices of different shapes. For cylindrical fire extinguishers, symmetrical arc-shaped clamps are often used to distribute pressure by increasing the contact area. For square or irregularly shaped fire extinguishers, adjustable grippers combined with flexible pads are employed, such as multi-segment hinged contour-following modules at the ends of the clamping arms. In some special scenarios, such as vehicle-mounted fire extinguisher racks, shock-absorbing designs are incorporated, with shock-absorbing springs or hydraulic dampers installed between the clamping mechanism and the base to prevent the device from detaching due to bumps during transport.

[0036] Driven by the trend towards intelligentization, some existing technologies are beginning to integrate sensors and feedback systems. For example, pressure sensors are installed inside clamping mechanisms to trigger audible and visual alarms when the clamping force falls below a safety threshold; or infrared detection is used to determine whether a fire extinguishing device is in place and transmits the status information to a central monitoring system. While these additional functions improve management efficiency, they also increase system complexity and cost, and are not yet widespread in basic products.

[0037] The limitations of existing technologies mainly lie in the challenge of balancing insufficient dynamic adaptability with operational efficiency. While traditional bolt-fastening methods provide reliable fixation, they struggle to enable rapid deployment and retrieval in emergencies. Purely elastic compression structures, though simple to operate, cannot meet the stability requirements of fire extinguishing devices of varying weights. Furthermore, most clamping mechanisms are designed for a single fixing point, lacking multi-point coordinated fixing solutions for large fire extinguishing devices exceeding 1 meter in height, making them prone to upper-level swaying in vibrating environments. These technical challenges are driving the design of clamping mechanisms towards greater intelligence and adaptability; however, existing solutions still require a better balance between ease of use, structural strength, and cost control.

[0038] Please see Figure 1-4 As shown, this embodiment provides a storage fire extinguishing device placement rack clamping mechanism, including: a mounting plate 3, a positioning clamping component on the upper part of the mounting plate 3, a plurality of support legs 2 mounted on the upper part, and a fixing box 1 mounted on the upper end surface of the plurality of support legs 2;

[0039] Two intersecting Z-shaped scissor arms 12 are rotatably mounted inside the fixed box 1. One Z-shaped scissor arm 12 is located above the other Z-shaped scissor arm 12. One end of each Z-shaped scissor arm 12 is rotatably connected to a first arc-shaped clamping plate 17, which is located on one side of the fixed box 1. Multiple rectangular storage boxes 18 are mounted on the side of the first arc-shaped clamping plate 17. The multiple rectangular storage boxes 18 are vertically equidistant. Connectors are elastically fitted inside the rectangular storage boxes 18, and the connectors penetrate horizontally through the corresponding boxes. The first arc-shaped clamping plate 17 has an arc-shaped rubber plate 22 installed at one end of the connector. The first arc-shaped clamping plate 17 is located between the arc-shaped rubber plate 22 and the rectangular storage box 18. The arc-shaped rubber plate 22 is located between the two first arc-shaped clamping plates 17. An electric push rod 9 is installed on the side of the fixed box 1 away from the first arc-shaped clamping plate 17. The output shaft of the electric push rod 9 is fixedly connected to a conical head 10. The conical head 10 is slidably fitted in the fixed box 1. The conical head 10 corresponds to the two Z-shaped scissor arms 12.

[0040] One application of this embodiment is as follows: In use, first, the mounting plate 3 is fixed to the target position. Then, the fire extinguishing device is placed on the mounting plate 3, with its bottom positioned at the positioning clamp. The positioning clamp clamps the bottom of the energy-storing fire extinguishing device. Then, the electric push rod 9 is activated to extend, and its output shaft drives the conical head 10 to slide towards the Z-shaped scissor arms 12. The inclined surface of the conical head 10 simultaneously contacts and presses the ends of the two intersecting Z-shaped scissor arms 12, causing the two first arc-shaped clamping plates 17 connected at their ends to move closer together. This allows the arc-shaped rubber plate 22 to elastically press against the surface of the fire extinguishing device. The tightening of the first arc-shaped clamping plate 17 and the elastic pressure of the arc-shaped rubber plate 22 together achieve stable clamping of the fire extinguishing device. Similarly, the fire extinguishing device can be quickly disassembled by referring to the above operation. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0041] By cooperating with the fixed box 1, support leg 2 and mounting plate 3, the first arc-shaped clamping plate 17 is raised above the positioning clamping member, so that the clamping mechanism can simultaneously clamp and fix the bottom and middle or upper part of the fire extinguishing device, improving the stability of the fire extinguishing device being clamped. At the same time, the electric push rod 9 extends and drives the conical head 10 to squeeze the two intersecting Z-shaped scissor arms 12, so that the two first arc-shaped clamping plates 17 are brought closer to each other, which facilitates the quick clamping or release of the fire extinguishing device and improves the efficiency of the fire extinguishing device retrieval operation. The arc-shaped rubber plate 22 cooperates with the elastic connector in the rectangular storage box 18 to make the clamping pressure of the clamping mechanism on the fire extinguishing device evenly distributed, reducing the risk of damage to the surface of the fire extinguishing device during the clamping process, and further enhancing the stability of the fire extinguishing device clamping through elastic pressing.

[0042] like Figure 1As shown, the mounting plate 3 in this embodiment is provided with multiple vertical insertion holes, which penetrate the mounting plate 3. The mounting plate 3 is provided with bolts 4 corresponding to the insertion holes, and the lower end of the bolts 4 penetrates the corresponding insertion holes. By cooperating with the insertion holes and bolts 4, it is convenient to install the clamping mechanism in the energy storage container that carries lithium batteries.

[0043] like Figure 1 , 3 As shown, the positioning clamping component in this embodiment includes a motor 5 mounted on one side of the mounting plate 3. The output shaft of the motor 5 is fixedly connected to a bidirectional screw 6. A groove is provided on the upper side of the mounting plate 3, and the bidirectional screw 6 passes through the groove laterally. Two sliding plates 8 are slidably fitted inside the groove. The sliding plates 8 are threadedly fitted around the periphery of the bidirectional screw 6. A second arc-shaped clamping plate 7 is mounted on the upper side of the sliding plate 8 and is slidably fitted on the top of the mounting plate 3. A backup power supply is installed on the upper side of the inner wall of the fixing box 1. The backup power supply corresponds to the electric push rod 9 and the motor 5. When a fire or circuit failure occurs, the backup power supply can supply power to the electric push rod 9 and the motor 5, so that the clamping mechanism can release the clamping and fixing of the fire extinguishing device. The motor 5 drives the bidirectional screw 6 to rotate, causing the two sliding plates 8 to move closer or further apart, thereby using the two second arc-shaped clamping plates 7 to move closer together to perform initial clamping and positioning of the bottom of the fire extinguishing device.

[0044] like Figure 2 As shown, a shaft is installed on the lower side of the inner wall of the fixed box 1 in this embodiment. The middle part of the Z-shaped scissor arm 12 is rotatably fitted on the periphery of the shaft. An anti-detachment circular plate is installed on the upper end face of the shaft. The shaft and the anti-detachment circular plate limit the middle part of the Z-shaped scissor arm 12, improve the stability of the rotation of the Z-shaped scissor arm 12, and reduce the probability of the Z-shaped scissor arm 12 detaching from the shaft.

[0045] like Figure 2 As shown, a fixing plate 13 is installed on the lower side of the inner wall of the fixing box 1 in this embodiment. Fixing posts 14 are installed between the two sides of the inner wall of the fixing box 1 and the fixing plate 13. A strip groove is provided at one end of the Z-shaped scissor arm 12, and the strip groove passes through the Z-shaped scissor arm 12. The fixing posts 14 pass through the corresponding strip grooves. A first spring 15 is sleeved around the fixing posts 14. One end of the Z-shaped scissor arm 12 is located between the fixing plate 13 and the corresponding first spring 15. The strip groove reduces the probability of the fixing posts 14 affecting the rotation of the Z-shaped scissor arm 12. When the conical head 10 releases the pressure on the Z-shaped scissor arm 12, the first spring 15 pushes the Z-shaped scissor arm 12 to quickly rotate in the opposite direction and reset.

[0046] like Figure 2As shown, in this embodiment, a rod is installed on the upper side of one end of the Z-shaped scissor arm 12, a bearing is installed around the rod, a rotating cylinder 11 is installed around the bearing, a conical head 10 is located between the two rotating cylinders 11, and a fixing plate 13 is located between the rod and the shaft. By cooperating with the rod, the bearing and the rotating cylinder 11, the contact friction between the conical head 10 and the Z-shaped scissor arm 12 is reduced, which facilitates the smooth pushing of the Z-shaped scissor arm 12 by the conical head 10.

[0047] like Figure 1 , 2 As shown in this embodiment, a U-shaped frame 16 is installed at one end of the Z-shaped scissor arm 12, and a connecting column is installed between the upper and lower sides of the U-shaped frame 16. A convex plate is provided on the side of the first arc-shaped clamping plate 17, and the convex plate is rotatably fitted around the connecting column. The shaft is located between the fixed plate 13 and the U-shaped frame 16. Through the rotational connection between the U-shaped frame 16 and the connecting column and the convex plate, the first arc-shaped clamping plate 17 can rotate slightly within a certain angle range, which facilitates the adaptive adjustment of the angle of the first arc-shaped clamping plate 17 during the clamping process.

[0048] like Figure 4 As shown, the connector in this embodiment includes a limiting plate 20 that slides within a rectangular storage box 18. A sliding rod 21 is installed between the limiting plate 20 and the corresponding arc-shaped rubber plate 22. The sliding rod 21 passes through a first arc-shaped clamping plate 17. A second spring 19 is provided between the limiting plate 20 and one side of the inner wall of the rectangular storage box 18. The limiting plate 20 is located between the second spring 19 and the sliding rod 21. When the arc-shaped rubber plate 22 is obstructed, the sliding rod 21 can enter the rectangular storage box 18, thereby causing the limiting plate 20 to compress the second spring 19. Through the cooperation of the limiting plate 20 and the first arc-shaped clamping plate 17, the probability of the sliding rod 21 falling off is reduced.

[0049] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
