Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishers, and in particular to a suspended dry powder fire extinguishing device. Background Art

[0002] Hanging fire extinguishers are generally installed in key flammable and explosive areas, and are mainly used in drying rooms, substation equipment, laboratories, warehouses, paint warehouses and other places. They contain a certain weight of dry powder fire extinguishing agent. When the temperature reaches 68°C, the temperature detection glass tube will automatically burst, and the sprinkler head will automatically spray dry powder to extinguish the fire.

[0003] Since the current hanging dry powder fire extinguishers are mainly hung on the ceiling in a fixed form, a hanging ring is provided on it. For example, a hanging dry powder fire extinguisher with patent publication number CN215136307U includes: a storage tank 1, a hanging ring 8, and a container valve 2. The storage tank 1 is filled with pressurized gas and fire extinguishing powder. The top of the storage tank 1 is provided with a container valve 2 connected to the inside. When the container valve 2 is opened, the fire extinguishing powder will be sprayed out under the action of pressure. The hanging ring 8 is connected to the bottom of the storage tank 1 and is used to connect with a circular ring preset on the fixed surface to achieve suspension.

[0004] However, due to the high ceiling, the use of a fixed hanging method requires climbing when replacing and repairing the fire extinguisher after installation, which reduces the installation and disassembly efficiency of the suspended fire extinguisher. Therefore, the present application proposes a suspended dry powder fire extinguishing device with high installation and disassembly efficiency. Summary of the invention

When the elastic locking block is separated from the conical portion, it pops out and abuts against the bottom of the conical portion.

[0013] The separation mechanism includes an elastic push block, a second limiting rod, a second spring, a third spring and a push rod.

[0046] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0047] Embodiment 1:

[0048] like Figures 1 to 6 As shown, the present invention provides a suspended dry powder fire extinguishing device, comprising:

[0049] The fire extinguisher body 1 is provided with a hanging portion 11 for hanging and fixing the fire extinguisher body 1;

[0050] The suspension device 2 is fixed to the ceiling by bolts to be used as a suspension frame for the fire extinguisher body 1;

[0051] The locking mechanism 3 is arranged in the hanging device 2. The hanging part 11 is inserted into the hanging device 2 so that the locking mechanism 3 locks the fire extinguisher body 1, thereby fixing the fire extinguisher body 1 in the hanging device 2.

[0052] The separation mechanism 4 is arranged in the suspension device 2 and is movably connected with the locking mechanism 3, so that the fire extinguisher body 1 can move by ascending and then descending, so that the separation mechanism 4 pushes the locking mechanism 3 to move to unlock the suspension part 11, thereby separating the fire extinguisher body 1 from the suspension device 2.

[0053] See also Figure 2 The suspension device 2 of the present application includes a mounting plate 21 and an annular ceiling 22, and the annular ceiling 22 is fixed to the ceiling through the mounting plate 21; specifically, a plurality of mounting holes for installation are provided on the annular ceiling 22, so that the annular ceiling 22 can be fixed to the ceiling by bolts.

[0054] See also Figures 4 to 6 The locking mechanism 3 of the present application includes an elastic locking block 31, a first limiting rod 32 and a first spring 33. The elastic locking block 31 is slidably arranged in the slide groove 221 of the annular hanging top 22. The first limiting rod 32 is located in the slide groove 221 and is slidably connected with the annular hanging top 22. The first spring 33 is sleeved on the first limiting rod 32, and the elastic locking block 31 is fixedly connected with the first limiting rod 32. A conical portion 111 is provided at the upper end of the hanging portion 11. The conical portion 111 pushes the elastic locking block 31 to squeeze the first spring 33 and shrink into the annular hanging top 22 by rising. When the elastic locking block 31 is separated from the conical portion 111, it pops out and abuts against the bottom of the conical portion 111, so that the end face of the elastic locking block 31 contacts the lower end face of the conical portion 111, thereby fixing the fire extinguisher body 1.

[0055] Specifically, the locking mechanisms 3 of the present application are provided in 2-4 groups, and the separation mechanisms 4 are provided in 2-4 groups accordingly.

[0056] See also Figure 5and Figure 6 The separation mechanism 4 of the present application includes an elastic push block 41, a second limiting rod 42, a second spring 43, a third spring 44 and a push rod 45. The elastic push block 41 is slidably arranged in the slide groove 221, the second limiting rod 42 is located in the slide groove 221 and is slidably connected with the annular hanging top 22, the second spring 43 is sleeved on the second limiting rod 42, and the elastic push block 41 is fixedly connected with the second limiting rod 42; one end of the push rod 45 is slidably connected with the elastic push block 41, the third spring 44 is sleeved on the push rod 45, and the other end of the push rod 45 is slidably limited in the elastic locking block 31; the conical portion 111 rises to the upper end of the elastic push block 41 and abuts against its inclined surface, and pushes the elastic push block 41 to retract due to the gravity of the fire extinguisher body 1, so that the push rod 45 pushes the elastic locking block 31 to unlock the hanging portion 11 by contraction. When the fire extinguisher body 1 is subjected to an upward thrust, the elastic push block 41 is pushed to retract by the inclined surface of the tapered portion 111, so that the tapered portion 111 passes vertically through the elastic push block 41 and then falls down by its own gravity, so that its edge abuts against the inclined surface of the elastic push block 41 and then pushes the elastic push block 41 to fall and then retract, so that the tapered portion 111 passes vertically. During this process, the elastic locking block 31 follows the elastic pushing block 41 to perform synchronous retraction movement, so that the descending tapered portion 111 does not contact the upper end surface of the elastic locking block 31, thereby achieving unlocking of the fire extinguisher body 1.

[0057] Since the fire extinguisher body 1 generates a reaction force when spraying dry powder, this reaction force can be used as an unlocking force to make the fire extinguisher body 1 fall to a certain height to spray powder on the fire point at close range, so as to realize the automatic descent of the fire extinguisher body 1 for fire extinguishing, which is suitable for fire extinguishing in buildings with high ceilings.

[0058] Embodiment 2:

[0059] As another embodiment of the present application, Figure 3 As shown, the annular ceiling 22 of the present application is provided with a limiting groove 222 for limiting the second limiting rod 42, and one end of the limiting slide groove 221 is provided with a spring groove for sliding abutment of the second spring 43, and the end of the second spring 43 is slidably arranged in the spring groove through a limiting ring, so that when the second limiting rod 42 vertically descends in the limiting groove 222, it can drive the second spring 43 to descend in the spring groove.

[0060] See also Figure 6The elastic locking block 31 of the present application is provided with a rectangular limiting groove 311, and the end of the push rod 45 is horizontally slidably limited in the rectangular sliding groove 62, so that when the tapered portion 111 abuts against the inclined surface of the elastic locking block 31 to push it to contract, the elastic push block 41 remains stationary under the action of the second spring 43; when the tapered portion 111 abuts against the inclined surface of the elastic push block 41 to push it to contract, the elastic locking block 31 follows the elastic push block 41 to perform synchronous contraction movement. In this embodiment, the lower end of the push rod 45 is limited by the rectangular limiting groove 311, and when the push rod 45 moves horizontally in the rectangular limiting groove 311, the elastic locking block 31 can be pushed to follow the elastic pushing block 41 to perform synchronous contraction movement; and when the elastic locking block 31 contracts under the push of the tapered portion 111, the rectangular limiting groove 311 is used to keep the elastic pushing block 41 stationary or move a small distance, so that the tapered portion 111 rises to be located between the elastic pushing block 41 and the elastic locking block 31, and when the elastic locking block 31 pops out under the action of the first spring 33, the upward force applied to the fire extinguisher body 1 can be stopped. At this time, after the force is canceled or reduced, the tapered portion 111 is driven down by the gravity of the fire extinguisher body 1 to contact and lock with the upper end surface of the popped-out elastic locking block 31.

[0061] Embodiment three:

[0062] As another embodiment of the present application, Figures 7 to 15 As shown, both ends of the annular hanging top 22 of the present application are connected with a horizontal hanging 5, a hanging rod 6 is slidably arranged inside the horizontal hanging 5, one end of the hanging rod 6 is provided with an elastic connecting mechanism 7, and a hanging ring 13 is provided on the fire extinguisher body 1, and the hanging rod 6 is detachably connected to the hanging ring 13 through the elastic connecting mechanism 7, so as to facilitate the removal of the fire extinguisher body 1 from the hanging rod 6.

[0063] See also Fig. 9 The elastic connection mechanism 7 of the present application includes a U-shaped member 71, a fourth spring 72 and a connecting bolt 73. A rectangular frame 61 is protruded from one end of the hanging rod 6, and the U-shaped member 71 is slidably arranged in the rectangular frame 61; the fourth spring 72 is arranged in the rectangular frame 61 and abuts against the end of the U-shaped member 71; protrusions are arranged at both ends of the U-shaped member 71, and rectangular through holes for limiting the protrusions are arranged on both sides of the rectangular frame 61 to limit the U-shaped member 71 and prevent the U-shaped member 71 from being separated from the rectangular frame 61; by arranging the fourth spring 72 and the U-shaped member 71, the upward movement margin of the fire extinguisher body 1 can be increased when it is lifted and unlocked, so that it can normally rise and contact the separation mechanism 4 to unlock the tapered portion 111.

[0064] See also Fig.10The end of the hanging rod 6 of the present application is provided with a rectangular slide 62, in which a rectangular lock block 8 is slidably provided, and the end of the rectangular lock block 8 is connected to a third limiting rod 9, which is slidably connected to the end of the hanging rod 6, and a fifth spring 10 is sleeved on the third limiting rod 9, and the fifth spring 10 abuts against the rectangular lock block 8; the rectangular lock block 8 is elastically plugged into the limiting groove 222; the circular limiting block abuts against the rectangular lock block 8 by sliding in the limiting circular groove, so as to push the rectangular lock block 8 to retract and disengage from the limiting groove 222 to unlock the end of the hanging rod 6. The two sides of the horizontal hanging 5 are provided with limited slideways 51, and the two sides of one end of the hanging rod 6 are provided with limited circular blocks 63, and the limited circular blocks 63 are slidably located in the limited slideways 51.

[0065] Furthermore, a rack is provided inside the limiting slide of the present application, and the limiting circle 63 is rotatably connected to one end of the hanging rod 6. The outer ring of the limiting circle 63 is provided with a circle of teeth, and the teeth are meshed with the rack to increase the resistance of the limiting circle 63 sliding in the limiting slide 51, thereby slowing down the hanging rod 6 and the tapered portion 111 after being unlocked, and being able to slowly descend under the gravity of the fire extinguisher body 1.

[0066] The working principle of the present application is as follows: the annular ceiling 22 is fixed to the ceiling by bolts, and the conical portion 111 of the hanging portion 11 is vertically inserted into the middle part of the annular ceiling 22, so that its annular inclined surface pushes the inclined surface of the elastic locking block 31 to make the elastic locking block 31 retract, and after the conical portion 111 vertically passes through the elastic locking block 31, the elastic locking block 31 pops out under the action of the first spring 33 so that its upper end surface fits with the lower end surface of the conical portion 111 to lock the hanging portion 11; when it is necessary to unlock the suspended fire extinguisher body 1, the fire extinguisher body 1 is pushed upward to move, so that the conical portion 111 rises and pushes the elastic push block 41 to contract so that the conical portion 111 passes vertically through the elastic push block 41, and descends under the action of its gravity to push the elastic push block 41 to contract so that the conical portion 111 passes vertically, and the elastic push block 41 contracts during the contraction process, so that the conical portion 111 can pass vertically through the elastic lock block 31 to be unlocked.
