Description

Technical Field

[0001] The utility model relates to the technical field of heptafluoropropane fire extinguishing devices, in particular to a highly stable heptafluoropropane fire extinguishing device. Background Art

[0002] Fluoropropane fire extinguishing agent is clean, low in toxicity, has good electrical insulation, high fire extinguishing efficiency, does not damage the atmospheric ozone layer, and will not cause damage to financial and precision facilities. Currently, the heptafluoropropane gas tank inside the cabinet-type heptafluoropropane fire extinguishing device is fixed to the inside of the cabinet by a clamp.

[0003] The publication number of the existing public technology is: CN218774212U. A cabinet-type heptafluoropropane fire extinguishing device includes a cabinet body, and a stabilizing mechanism is fixedly installed inside the cabinet body. The stabilizing mechanism includes a fixing plate, and the fixing plate is fixedly installed at a corresponding position of the inner wall of the cabinet body. The screw can be driven to rotate by a knob, a worm, and a worm gear. The screw drives the arc plate to slide out of the fixing plate through the gear and the teeth, and blocks it on the outside of the heptafluoropropane gas tank, thereby limiting the heptafluoropropane gas tank. At the same time, the screw drives the adjustment plate to slide up through the screw hole, and blocks the adjustment plate at the bottom end of the heptafluoropropane gas tank, which can provide stability of the heptafluoropropane gas tank and is easy to operate. The dust cover can prevent the nozzle from being blocked by dust, etc., and the practicability is high.

[0004] Combining the above patents with actual production and living conditions, it is not difficult to find that: when replacing the heptafluoropropane gas cylinder, it is necessary to manually enter the cabinet to move the gas cylinder down and then install the new gas cylinder. After the heptafluoropropane gas cylinder is placed in the cabinet, the remaining operating space is small. Replacing the heptafluoropropane gas cylinder is time-consuming and labor-intensive, and inconvenient to use. The overall operation process consumes a lot of labor from the personnel, which not only increases the labor intensity of the personnel, but also increases the risk of the handling operation due to the influence of the gas cylinder's own weight during transportation. There are certain safety hazards. At the same time, the overall fixing measures are relatively single, which is not conducive to a more stable fixation of the tank, and the use effect is not very ideal.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-4 As shown, a highly stable HFC-227ea fire extinguishing device according to an embodiment of the utility model includes a storage cabinet 1 and a nozzle 2, a screw rod 6 is installed on the surface of one side inside the storage cabinet 1, one end of the screw rod 6 passes through one side of the storage cabinet 1 and is connected to a brake motor 4, a sleeve 8 is symmetrically welded on the outer periphery of the screw rod 6, a clamping arm 7 is fixedly welded on one end of the sleeve 8, a limiting groove 10 is symmetrically provided on the inner surface of one end of the clamping arm 7, a fixing frame 17 is welded on one end of the clamping arm 7 facing the inner wall of the storage cabinet 1, a torsion lever 16 is rotatably connected to the top position of the surface of one side of the fixing frame 17, a spring protrusion 18 is rotatably connected to the bottom surface of the fixing frame 17 below the torsion lever 16, and a plurality of groups of spring retaining rings 11 are symmetrically provided at the bottom end of the storage cabinet 1 directly below the support arm.

[0032] In one embodiment, a limiting groove 14 is symmetrically provided at the bottom of one side surface of the storage cabinet 1, a hydraulic rod 13 is fixedly installed inside the limiting groove 14, and a supporting plate 12 is fixedly installed on the top of the hydraulic rod 13. The supporting plate 12 is provided to move the gas tank up and down, thereby reducing the labor intensity when replacing personnel.

[0033] In one embodiment, a HFC-227ea gas cylinder 9 is abutted against the inner position of the limiting groove 10. The HFC-227ea gas cylinder 9 is a common structure and will not be described in detail herein.

[0034] In one embodiment, a pipe 5 is installed at the top of the heptafluoropropane gas tank 9, one end of the pipe 5 is connected to the nozzle 2, and the nozzle 2 is located in the middle of the top surface of one side of the storage cabinet 1, and a solenoid valve 3 is installed between the pipe 5 and the nozzle 2. The solenoid valve 3 is configured to open when a dangerous situation occurs in the outside world so that the fire extinguishing medium inside the heptafluoropropane gas tank 9 can be sprayed out through the nozzle 2 to achieve fire extinguishing operation.

[0035] In one embodiment, a sealing door 15 is rotatably connected to the surface of one side of the storage cabinet 1. The sealing door 15 is used to seal the interior of the storage cabinet 1 to improve the protection effect of the gas tank.

[0036] In one embodiment, return springs are installed at the bottom of the spring retaining ring 11 and the spring protrusion 18, and torsion springs are sleeved at both ends of the torsion lever 16. The different types of springs are set according to the different functions of the above-mentioned structures. The return spring is to ensure that the two groups of structures can be smoothly deformed and reset, and the torsion spring is to ensure that the torsion lever 16 can return to its original position after rotation.

[0037] In one embodiment, the spring protrusion 18 is a triangular structure. The triangular structure is provided on the one hand to facilitate the use of the torsion lever 16, and on the other hand to block the torsion lever 16 through its side after the torsion lever 16 is reset, to prevent the torsion lever 16 from flexibly moving and causing the clamping arm 7 to slide out, thereby ensuring stability in use.

[0039] Working principle: In actual use, when it is necessary to replace the HFC-227ea gas cylinder 9 inside the storage cabinet 1, first press the spring protrusion 18 and the spring retaining ring 11 to make the two fall back downward, and then the operation of the brake motor 4 can drive the screw rod 6 to rotate, and then drive the clamping arm 7 to rotate outward as a whole, so as to move the gas cylinder out as a whole, and at the same time, the hydraulic rod 13 can be used to lift the supporting plate 12 to a position that is flush with the bottom, so that the moved gas cylinder can abut against the surface position of the supporting plate 12 to avoid the height difference causing the gas cylinder to continue to fall when it is moved out, and then the gas cylinder can be taken out and replaced, and then after the gas cylinder is replaced, the secondary lifting of the supporting plate 12 can lift the gas cylinder as a whole to the bottom position of the cabinet, and then the screw rod 6 can be reversed to move the gas cylinder to the inside of the cabinet. At this time, the bottom of the gas tank will exert pressure on the spring retaining ring 11 to make it It moves downward, and then after the gas tank moves over, the spring reset at its bottom will lift up the spring retaining ring 11 again and restrain it at the bottom position of the gas tank, so that the bottom of the gas tank can be limited. At the same time, the movement of the gas tank will cause the clamping arm 7 to move to the fixed frame 17. At this time, the clamping arm 7 will first push the torsion lever 16 so that it will squeeze the spring protrusion 18 as a whole to ensure that the clamping arm 7 can move smoothly to the inside of the fixed frame 17. When moving to the inside, the spring protrusion 18 and the torsion lever 16 are reset due to the spring and torsion spring at the connection between the spring protrusion 18 and the torsion lever 16, and the torsion lever 16 can abut against the side position of the spring protrusion 18, thereby preventing the clamping arm 7 from detaching from the fixed frame 17 during subsequent use, thereby improving the fixing effect of the gas tank and improving the overall stability. The device as a whole has the advantages of labor-saving replacement, strong stability and multiple fixations.
