Description

Technical Field

[0001] This utility model relates to the technical field of dual-cabinet fire extinguishing devices, specifically a dual-cabinet fire extinguishing device. Background Technology

[0002] The dual-cabinet fire extinguishing system is a common type of automatic fire extinguishing system, typically consisting of two gas cylinders and related components. It is characterized by high efficiency and convenience and is widely used in various key fire protection locations. It mainly consists of extinguishing agent cylinder groups, clamp-type fixing structures, pipelines, nozzles, signal feedback components, leak detection components, drive components, fire detection components, controllers, etc. When a fire occurs, the system detects an anomaly through smoke or heat detectors, triggering the control unit. The control unit then starts and opens the valve in the gas cylinder cabinet to release heptafluoropropane gas.

[0003] In the existing technology, the clamp-type fixing structure consists of clamps, insert rods and adjusting nuts. When fixing two gas cylinders, assemble two clamps, three insert rods and three adjusting nuts, then insert the insert rods into the fire extinguishing cabinet, and then rotate the adjusting nuts to make the clamps fit tightly against the gas cylinders, thereby completing the fixing. In the actual process of fixing gas cylinders, the three insert rods and three adjusting nuts correspond to different force points. It is difficult to ensure synchronous force during rotation and adjustment, which can easily lead to situations where the clamp at one insert rod is too tight and the clamp at another is too loose. This causes the two gas cylinders to be unevenly stressed, resulting in one side being tightly pressed against the cabinet and the other side wobbling. Moreover, it is necessary to repeatedly adjust the tightness of each nut to match the size of the two gas cylinders, which not only affects the fixing effect but also makes the operation cumbersome. Therefore, a dual-cabinet fire extinguishing device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dual-cabinet fire extinguishing device, which has the advantages of simple operation and stable fixation. It solves the problem that when three plug rods and three adjusting nuts correspond to different force points, it is difficult to ensure synchronous force during rotation and adjustment. This can easily lead to situations where the clamp at one plug rod is too tight and the clamp at another is too loose. As a result, the two gas cylinders are subjected to uneven force, with one side sticking to the cabinet and the other side shaking. Moreover, it is necessary to repeatedly adjust the tightness of each nut to match the size of the two gas cylinders, which not only affects the fixation effect but also makes the operation cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-cabinet fire extinguishing device, comprising a fire extinguishing cabinet and two gas cylinders, wherein the fire extinguishing cabinet is provided with an installation structure for installing and fixing the gas cylinders; The installation structure includes a support component for initially restricting the gas cylinder, and the support component is installed inside the fire extinguishing cabinet. The support component is provided with four positioning parts for fixing the gas cylinder, and the support component is provided with a connecting part for moving the positioning parts. The supporting component includes a supporting bridge installed inside the fire extinguishing cabinet. An electric push rod is fixedly installed on the supporting bridge and connected to the connecting component. A guide rod for limiting the movement trajectory of the connecting component is fixedly installed on the supporting bridge. The supporting bridge is provided with two pockets that respectively contact the gas cylinder, and a positioning component is slidably installed on the pockets. The connecting component includes a connecting plate, which is fixedly connected to the telescopic end of the electric push rod. Four symmetrically distributed connecting rods are hinged on the connecting plate, and one end of each connecting rod is hinged to a positioning component.

[0006] Furthermore, the positioning component includes an arc-shaped positioning plate for fixing the gas storage cylinder, and the arc-shaped positioning plate is slidably connected to the pocket. An anti-detachment plate is fixedly installed on the arc-shaped positioning plate, and two limiting blocks are fixedly installed on the arc-shaped positioning plate.

[0007] Furthermore, the support bridge has two guide holes, and one end of the guide rod passes through the guide hole and extends to the outside of the support bridge. The guide hole and the guide rod are slidably connected.

[0008] Furthermore, the four positioning elements are symmetrically distributed on the support bridge, and the two positioning elements on the same side are also symmetrically distributed on the pocket.

[0009] Furthermore, the support bridge has several symmetrically distributed mounting holes.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This dual-cabinet fire extinguishing device is equipped with connecting components and four positioning components. The extension and retraction movement of the electric push rod is transmitted to the four connecting rods through the connecting plate, thereby ensuring that the four positioning components move synchronously. The four positioning components are symmetrically distributed. Through the linkage of the connecting rods, uniform pressure is applied to the gas cylinder at the same time, thereby simplifying the gas cylinder installation and fixing steps and making the force even when the gas cylinder is fixed. 2. This dual-cabinet fire extinguishing device uses an arc-shaped positioning plate in the positioning component to fit the curved surface of the cylinder. Together with the anti-detachment plate, limiting block, and pocket, it forms a ring-shaped fixation, thereby increasing the contact area with the gas cylinder and improving the stability of the fixed installation of the gas cylinder. 3. The four positioning components of this dual-cabinet fire extinguishing device are symmetrically distributed on the left and right, and the two positioning components on the same side are also symmetrical to the pocket, so that the stress center of the gas cylinder coincides with the geometric center, avoiding the impact of the center of gravity shift on the subsequent pipeline connection of the gas cylinder, and avoiding the deformation of the cylinder body caused by local stress concentration.

[0013] 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.

[0014] Example 1: Please refer to Figure 1-5 The dual-cabinet fire extinguishing device in this embodiment includes a fire extinguishing cabinet 1 and two gas cylinders 2. The fire extinguishing cabinet 1 is provided with an installation structure 3 for installing and fixing the gas cylinders 2.

[0015] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the installation structure 3 includes a support component 31 for initially restricting the gas cylinder 2, and the support component 31 is installed inside the fire extinguishing cabinet 1. The support component 31 is provided with four positioning parts 32 for fixing the gas cylinder 2, and the support component 31 is provided with a connecting part 33 for moving the positioning parts 32. The support component 31 includes a support bridge 311 installed inside the fire extinguishing cabinet 1. An electric push rod 312 is fixedly installed on the support bridge 311 and is connected to the connecting component 33. A guide rod 313 for limiting the movement trajectory of the connecting component 33 is fixedly installed on the support bridge 311. The support bridge 311 is provided with two pockets 314 that respectively contact the gas cylinder 2, and the positioning component 32 is slidably installed on the pockets 314. The connecting component 33 includes a connecting plate 331, which is fixedly connected to the telescopic end of the electric push rod 312. Four symmetrically distributed connecting rods 332 are hinged on the connecting plate 331, and one end of the connecting rod 332 is hinged to the positioning component 32.

[0016] The support bridge 311 has two guide holes, and one end of the guide rod 313 passes through the guide hole and extends to the outside of the support bridge 311. The guide hole and the guide rod 313 are slidably connected. The guide rod 313 is slidably connected to the guide hole on the support bridge 311, which restricts the movement trajectory of the connecting component 33, so that the connecting rod 332 maintains a straight movement when pushing the positioning component 32, and avoids the gas storage bottle 2 from tilting due to uneven force.

[0017] In addition, four positioning components 32 are symmetrically distributed on the support bridge 311, and two positioning components 32 on the same side are also symmetrically distributed on the pocket 314. The four positioning components 32 are symmetrically distributed on the left and right, and the two positioning components 32 on the same side are also symmetrical to the pocket 314, so that the stress center of the gas storage cylinder 2 coincides with the geometric center, avoiding local stress concentration, and ensuring the stable installation of the gas storage cylinder 2.

[0018] It should be noted that the support cable tray 311 has several symmetrically distributed mounting holes 315, which can be used to fix the support cable tray 311 to the fire extinguisher 1 with bolts and mounting holes 315, thereby facilitating the installation of the structure 3 in the fire extinguisher 1.

[0019] By adopting the above technical solution, the electric push rod 312 drives the connecting plate 331 to move along the guide rod 313, which in turn drives the four connecting rods 332 to move synchronously. The two connecting rods 332 on the same side are respectively hinged to the two arc-shaped positioning plates 321 on the same side, so that the two connecting rods 332 on the same side unfold. The moving connecting rods 332 push the positioning piece 32 to slide along the pocket 314, which replaces the manual rotation of the adjusting nut and completely eliminates the defect of asynchronous three-point adjustment. Furthermore, when installing the gas cylinder 2, it is only necessary to place the gas cylinder 2 in the designated position and then start the electric push rod 312 to complete the fixing of the gas cylinder 2, thus simplifying the installation steps of the gas cylinder 2.

[0020] Example 3: Please refer to Figure 1-5Based on Embodiment 2, the positioning component 32 includes an arc-shaped positioning plate 321 for fixing the gas storage bottle 2, and the arc-shaped positioning plate 321 is slidably connected to the pocket 314. An anti-detachment plate 322 is fixedly installed on the arc-shaped positioning plate 321, and two limiting blocks 323 are fixedly installed on the arc-shaped positioning plate 321.

[0021] The above technical solution is adopted, and the positioning components 32 are symmetrically distributed. At the same time, uniform pressure is applied to the gas storage cylinder 2. The arc-shaped positioning plate 321 fits the curved surface of the cylinder body, and together with the anti-detachment plate 322 and the limiting block 323, it forms a ring-shaped fixation, and together with the pocket 314 on the support bridge 311, it ensures the stability of the gas storage cylinder 2.

[0022] The working principle of the above embodiments is as follows: When using this dual-cabinet fire extinguishing device, the two gas cylinders 2 are placed on the two pockets 314 of the support frame 311 respectively, so that the cylinders fit into the pockets 314 to complete the initial positioning. When the electric push rod 312 is activated, its telescopic end pushes the connecting plate 331 to move along the direction of the guide rod 313, which drives the four connecting rods 332 to move synchronously. The two connecting rods 332 on the same side are respectively hinged to the two arc-shaped positioning plates 321 on the same side, so that the two connecting rods 332 on the same side unfold. The moving connecting rod 332 pushes the positioning piece 32 to slide along the pocket 314, thereby controlling the four arc-shaped positioning plates 321 to gradually extend out of the support bridge 311, so that the two arc-shaped positioning plates 321 on the same side hug the gas cylinder 2 on the same side, thereby completing the rapid installation and fixing of the two gas cylinders 2. The positioning components 32 are symmetrically distributed and apply uniform pressure to the gas storage cylinder 2. The arc-shaped positioning plate 321 fits the curved surface of the cylinder and, together with the anti-detachment plate 322 and the limiting block 323, forms a ring-shaped fixation. It also works with the pocket 314 on the support bridge 311 to ensure the stability of the gas storage cylinder 2.
