Description

Technical Field

[0001] The invention relates to the technical field of fire fighting and extinguishing, in particular to a marine integrated high-multiplicity foam fire extinguishing device. Background Art

[0002] High-multiplicity foam generator is also called foam fire extinguisher. The fire extinguishing principle is that it can spray a large amount of carbon dioxide and foam when extinguishing a fire. They can adhere to the combustibles, isolating the combustibles from the air and achieving the purpose of extinguishing the fire. Foam fire extinguishers are divided into: portable foam fire extinguishers, trolley-type foam fire extinguishers and air-type foam fire extinguishers.

[0003] For example, Chinese patent CN214232492U discloses a mobile high-multiplicity foam fire extinguishing device. When fire extinguishing is needed, the foaming fire extinguishing agent in the storage tank is pushed into the discharge cylinder under the action of pressure, reacts with water, and is blown out by a fan, and gradually separated into fine foams through a separation net, and finally discharged along the fire hose through a pressure pump to complete the foam spraying, thereby quickly extinguishing the fire source and facilitating firefighters to quickly control the fire.

[0004] However, such as the above-mentioned reference documents, the high-expansion foam fire extinguishing device in the prior art still has the following problems during its use:

[0005] 1. The existing ship-used high-power foam fire extinguishing device has a fixed direction of its foam emission head, which needs to be manually rotated to change the direction. However, it is inconvenient to manually rotate the emission head in the fire scene and there are great safety hazards. When the fire in the cabin is large, the fire extinguishing position of the emission head cannot be automatically switched, and the fire extinguishing area is small, which easily leads to missing the best fire extinguishing time, causing the fire to increase, and is inconvenient to use.

[0006] 2. The foaming nets used in the high-expansion foam fire extinguishing devices in the prior art are mostly single-fan fixed structures. It is difficult to fully mix the foam mixture with the air during use, resulting in less foaming and more water droplets, which is not conducive to use. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] For example, see Figures 1 to 7 The present invention provides a marine integrated high-power foam fire extinguishing device, comprising a base 1, the upper surface of the base 1 is fixedly connected with four symmetrically arranged fixing columns, the base 1 is fixedly mounted with a foam generating tank 2 through the fixing columns, the surface of the foam generating tank 2 is fixedly connected with a connecting piece 3, the lower surface of the connecting piece 3 is provided with a connecting ring 5, the connecting piece 3 is connected with a connecting pipe 6 through the connecting ring 5, and the end of the connecting pipe 6 is fixedly connected with a foam emission head 7;

[0037] A motor 13 is fixedly mounted on the surface of the foam generating tank 2, and a fan 18 is fixedly connected to the output shaft of the motor 13. A rotating rod 20 is fixedly connected to the surface of the foam generating tank 2, and a fixed sleeve 21 is fixedly connected to the surface of the rotating rod 20. A plurality of separation nets 24 distributed in a circumferential array are fixedly mounted on the surface of the fixed sleeve 21. An annular notch 23 is provided on the inner wall of the foam generating tank 2, and a gear ring 25 is fixedly connected to the inner wall of the annular notch 23, and a separation net 22 is fixedly mounted on the inner wall of the gear ring 25.

[0038] A protective shell 4 is fixedly mounted on the surface of the foam generating tank 2 , and auxiliary components, switching components and cooling components are arranged inside the protective shell 4 .

[0039] A liquid storage cylinder 11 is fixedly mounted on the upper surface of the foam generating tank 2, a liquid outlet pipe 17 is fixedly connected to the surface of the liquid storage cylinder 11, and a pump body 16 is arranged on the surface of the liquid outlet pipe 17;

[0040] A water tank 2 12 is fixedly mounted on the upper surface of the base 1 , a water inlet pipe 19 is fixedly connected to the surface of the water tank 2 12 , and a pump body 2 is arranged on the surface of the water inlet pipe 19 .

[0041] The auxiliary component includes a support plate fixedly connected to the surface of the foam generating tank 2, the surface of the support plate is connected to a rotating shaft 26 for fixed-axis rotation, a bevel gear transmission mechanism 34 is provided between the rotating shaft 26 and the rotating rod 20, and the surface of the rotating shaft 26 is fixedly connected to a gear 27 meshing with the gear ring 25.

[0042] In this embodiment, when a small fire occurs in the cabin, a universal wheel is installed below the base 1, and the main body of the fire extinguishing device above the base 1 can be moved to the fire location under the action of the universal wheel.

[0043] like Figure 3 As shown, aim the foam launch head 7 at the fire source, turn on the pump body 16 and the pump body 2, and the foaming fire extinguishing agent can be transported to the foam generating tank 2 through the liquid outlet pipe 17, and the clean water will enter the foam generating tank 2 through the water inlet pipe 19. After the foaming fire extinguishing agent reacts with the clean water, a large amount of fire extinguishing foam can be generated. At the same time, turn on the motor 13 to make the fan 18 rotate. Under the action of the fan, the foam will first be blown to the separation net 1 24. After passing through multiple separation nets 1 24, the foam begins to be refined once. Moreover, due to the blowing action of the fan 18, the multiple separation nets 1 24 will start to rotate, so that the foam mixture can be fully mixed with the air in the foam generating tank 2. The foam refined by multiple separation nets 1 24 will also be refined for a second time through the separation net 22.

[0044] It is worth noting that Figure 4 , Figure 5 and Figure 6As shown, with the rotation of the multiple separation nets 1 24, the rotating rod 20 will also rotate synchronously. Under the action of the bevel gear transmission mechanism 34, the rotating shaft 26 will rotate synchronously. With the rotation of the rotating shaft 26, under the meshing action of the gear 1 27 and the gear ring 25, the separation net 2 22 will rotate. With the rotation of the multiple separation nets 1 24 and the separation net 2 22, the shear force and centrifugal force of the foam mixture during the foaming process can be increased, so that the foam mixture can be more evenly dispersed in the air, thereby improving the foaming effect. Compared with the traditional single-set fixed foaming net, the foaming effect is better and the water droplets are less, so that the foam finally sprayed from the foam launch head 7 to the fire source can have a better fire extinguishing effect.

[0045] Embodiment 2, based on the above embodiment:

[0046] Furthermore, the switching component includes a circular shell 36 that is fixedly rotatably connected to the surface of the rotating shaft 26, and an inner cavity 43 is formed inside the circular shell 36. Two symmetrically arranged abutment blocks 44 are fixedly connected to the inner wall of the inner cavity 43.

[0047] A rotating disk 45 is fixedly connected to the surface of the rotating shaft 26 . A rectangular slot 1 is opened on the surface of the rotating disk 45 . A moving block 48 is slidably connected to the inner wall of the rectangular slot 1 . A spring 47 is provided between the moving block 48 and the inner wall of the rectangular slot 1 .

[0048] Two symmetrically arranged sliding blocks 46 are fixedly connected to the side of the moving block 48, and the inner wall of the rectangular notch is provided with a sliding groove for the sliding blocks 46 to slide and move.

[0049] The switching component also includes a moving column 38 fixedly connected to the surface of the circular shell 36, the outer surface of the moving column 38 is slidably connected to a moving frame 37, the surface of the moving frame 37 is fixedly connected to a rack row 39, the surface of the rack row 39 is fixedly connected to a moving rod 41, the surface of the foam generating tank 2 is provided with a rectangular slot 40 for the moving rod 41 to extend and slide, and the surface of the connecting pipe 6 is fixedly connected to a gear 42 meshing with the rack row 39.

[0050] In this embodiment, when a large fire occurs in the cabin, similarly, the main body of the fire extinguishing device above the base 1 is first moved to the fire location, then the foam launcher 7 is aimed at the fire source, and then the maximum power of the motor 13 is turned on to make the fan 18 rotate at a high speed. Since the wind force driven by the fan 18 is relatively large at this time, the rotation speed of the multiple separation nets 24 can be increased, that is, the rotation speed of the rotating rod 20 and the rotating shaft 26 will be increased at this time.

[0051] like Figure 6 and Figure 7As shown, with the high-speed rotation of the rotating shaft 26, the turntable 45 will be driven to rotate at a high speed. At this time, under the action of the centrifugal force when the turntable 45 rotates, a part of the two moving blocks 48 can be rotated out of the outer side of the rectangular slot 1 and contact the abutment block 44. With the rotation of the moving block 48, the abutment block 44 and the circular shell 36 will be driven to rotate synchronously.

[0052] As the circular shell 36 rotates, the moving column 38 is driven to perform circular motion. Since the moving frame 37 is limited to move in the horizontal direction, the circular motion of the moving column 38 will cause the moving frame 37 to drive the rack row 39 to reciprocate in the horizontal direction. As the rack row 39 reciprocates, under the meshing action of the rack row 39 and the gear 2 42, the gear 2 42 will drive the connecting pipe 6 to rotate reciprocally, so that the foam launcher 7 under the connecting pipe 6 can rotate reciprocally, so that when the fire is large, the foam launcher 7 can have a larger fire extinguishing area. Similarly, since the motor 13 is also running at high power at this time, as the wind force of the fan 18 increases, more foam will be generated in the foam generating tank 2, so that effective fire extinguishing operations can be performed when a large fire occurs in the cabin.

[0053] Embodiment 3, based on the above embodiment:

[0054] Furthermore, the cooling component includes a hinged plate 31 hinged on the upper surface of the moving frame 37, the inner wall of the protective shell 4 is fixedly connected to two fixed blocks 29, the protective shell 4 is fixedly mounted with a piston cylinder 30 through the two fixed blocks 29, the inner wall of the piston cylinder 30 is slidably connected to a piston plate, the surface of the piston plate is fixedly connected to a piston rod 35, the end of the piston rod 35 extending out of the piston cylinder 30 is fixedly connected to a hinge block 32, and the end of the hinged plate 31 is hinged to the hinge block 32;

[0055] A water tank 15 is fixedly installed on the surface of the protective shell 4, and a connecting pipe 14 is fixedly connected between the water tank 15 and the piston cylinder 30. A connecting pipe 2 33 is fixedly connected to the surface of the piston cylinder 30. A one-way valve 1 is provided on the surface of the connecting pipe 14, and a one-way valve 2 is provided on the surface of the connecting pipe 2 33. The end of the connecting pipe 2 33 is fixedly connected to a water outlet pipe 8, and a plurality of atomizing nozzles 10 are evenly arranged on the surface of the water outlet pipe 8. A fixing rod is fixedly connected to the surface of the protective shell 4, and a fixing ring 9 is fixedly connected to the end of the fixing rod, and the water outlet pipe 8 passes through the fixing ring 9 and is fixedly connected thereto.

[0056] In this embodiment, Figure 1 , Figure 6 and Figure 7As shown, when a large fire occurs in the cabin, with the reciprocating movement of the movable frame 37, under the hinged action of the hinged plate 31, the piston rod 35 will drive the piston plate to perform piston movement in the piston cylinder 30, so that the clean water in the water tank 15 can be discharged to the water outlet pipe 8 through the connecting pipe 2 33 under the action of the negative pressure adsorption of the piston cylinder 30, and the clean water in the water outlet pipe 8 will finally be sprayed to the top of the foam generating tank 2 through multiple atomizing nozzles 10, so that the surface of the foam generating tank 2 can be cooled while the foam launch head 7 extinguishes the fire in the fire scene, so as to ensure the long-term use of the foam generating tank 2 in the cabin fire scene, and at the same time, the safety of the fire extinguishing equipment during use is improved, the structure is simple, and it is worthy of promotion and use.

[0057] Working principle: This is a kind of integrated high-multiple foam fire extinguishing device for ships. When in use, when a small fire occurs in the cabin, under the action of the universal wheel below the base 1, the main body of the fire extinguishing device above the base 1 is first moved to the fire scene, and the foam launch head 7 is aimed at the fire source, and then the pump body 16 and the pump body 2 are turned on, and the foaming fire extinguishing agent is transported to the foam generating tank 2 through the liquid outlet pipe 17, and the clean water will enter the foam generating tank 2 through the water inlet pipe 19. After the foaming fire extinguishing agent reacts with the clean water, a large amount of fire extinguishing foam can be generated. At the same time, the motor 13 is turned on to make the fan 18 rotate. Under the action of the fan, the foam will first be blown to the separation net 124, and after passing through multiple separation nets 24, the foam will begin to be refined once, and because of the blowing action of the fan 18, the multiple separation nets 24 will start to rotate, so that the foam mixture can be fully mixed with the air in the foam generating tank 2, and then, the foam refined by the multiple separation nets 24 will be refined for a second time through the separation net 22.

[0058] As the multiple separation nets 1 24 rotate, the rotating rod 20 and the rotating shaft 26 will rotate synchronously, and under the meshing action of the gear 1 27 and the gear ring 25, the separation net 2 22 will rotate. As the multiple separation nets 1 24 and the separation net 2 2 rotate, the shear force and centrifugal force of the foam mixture during the foaming process can be increased, so that the foam mixture is more evenly dispersed in the air, thereby improving the foaming effect. Compared with the traditional single-set fixed foaming net, the foaming effect is better and the water droplets are less, so that the foam finally sprayed from the foam launch head 7 to the fire source can have a better fire extinguishing effect.

[0059] When a large fire occurs in the cabin, the maximum power of the motor 13 is turned on to make the fan 18 rotate at a high speed. Since the wind force driven by the fan 18 is relatively large at this time, the rotation speed of the rotating rod 20 and the rotating shaft 26 can be accelerated. As the rotating shaft 26 rotates at a high speed, the turntable 45 will be driven to rotate at a high speed. Under the action of centrifugal force when the turntable 45 rotates, a part of the two moving blocks 48 can be rotated out of the outer side of the rectangular slot 1 and contact the abutment block 44. As the moving block 48 rotates, the abutment block 44 and the circular shell 36 will be driven to rotate synchronously.

[0060] As the circular shell 36 rotates, the movable frame 37 will drive the rack row 39 to reciprocate in the horizontal direction, so that the gear 2 42 can drive the connecting pipe 6 and the foam launch head 7 thereunder to reciprocate, so that when the fire is large, the fire extinguishing area can be increased by the reciprocating rotation of the foam launch head 7. Moreover, since the motor 13 is also running at high power at this time, as the wind force of the fan 18 increases, more foam will be generated in the foam generating tank 2, so that effective fire extinguishing operations can be performed when a large fire occurs in the cabin.

[0061] It is worth noting that with the reciprocating movement of the movable frame 37, under the hinged action of the hinged plate 31, the piston rod 35 will drive the piston plate to perform piston movement in the piston cylinder 30, so that the clean water in the water tank 15 can be sprayed to the top of the foam generating tank 2 through multiple atomizing nozzles 10, so that the surface of the foam generating tank 2 can be cooled while the foam launch head 7 extinguishes the fire in the fire scene, thereby ensuring the long-term use of the foam generating tank 2 in the cabin fire scene, and also improving the safety of the fire extinguishing equipment during use. It is worthy of promotion and use.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
