Description

Technical Field

[0001] This utility model belongs to the technical field of fire extinguishing equipment, and specifically relates to a portable foam fire extinguishing device. Background Technology

[0002] In the field of fire protection, portable foam fire extinguishing devices play a vital role. They can be quickly moved to the scene to carry out fire extinguishing operations when a fire occurs, which greatly improves the flexibility and timeliness of fire extinguishing operations. However, the design of the placement of foam guns and water hose reels in the portable foam fire extinguishing devices commonly found on the market still has obvious defects.

[0003] Many portable foam fire extinguishing systems are equipped with supports to hold the foam guns for storage and support when not in use. However, existing supports lack the function of securing the foam guns. When operators push the extinguishing system quickly to the fire scene, the complex and changing road conditions inevitably cause significant vibration and shaking during movement. The foam guns are prone to detaching from the supports and falling to the ground. Furthermore, portable foam fire extinguishing systems are usually equipped with frames for holding hose reels. Currently, these systems also cannot effectively secure the hose reels within the frames. During movement, the hose reels tend to shake and roll within the frames, and the loose, shaking hose reels may become tangled and knotted, preventing the hose from unfolding smoothly.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a portable foam fire extinguishing device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a portable foam fire extinguishing device, including a mobile vehicle. A foam liquid storage tank is installed on the top of the mobile vehicle. A proportioning mixer is installed on the top of the foam liquid storage tank. Supports are symmetrically installed on one side of the top of the foam liquid storage tank. Foam guns are installed on the top of the two supports. Fixed frames are symmetrically fixedly connected to the mobile vehicle. A hanging frame is fixedly connected between the two fixed frames. A rotating gear is rotatably installed at the center of one end of the hanging frame. Fixed mechanisms are symmetrically meshed on both sides of the rotating gear. The fixed mechanisms are slidably installed in the hanging frame. A connecting ring is fixedly installed on one side of the top of the bracket, and a rotating ring is also rotatably connected to one side of the top of the bracket. A binding strap is rotatably installed on the top of the connecting ring, and a hook and loop fastener surface and a hook and loop fastener surface are fixedly installed on one end of the binding strap, respectively.

[0007] Furthermore, the fixing mechanism includes a movable plate, which is slidably connected to the hanging frame. Fixed rollers are fixedly installed at both the upper and lower ends of the movable plate, and both fixed rollers are located in the inner cavity of the hanging frame.

[0008] Furthermore, a rack is fixedly installed at one end of the movable plate, the rack meshes with the rotating gear, and a pull rod is fixedly installed at the end of the movable plate away from the rack, the pull rod being slidably installed on the fixed frame.

[0009] Furthermore, an elastic element is sleeved on the outside of the pull rod, one end of the elastic element is fixedly installed on the fixed frame, and the other end of the elastic element away from the fixed frame is fixedly installed on the movable plate.

[0010] Furthermore, the bottom of the hanging frame is provided with several water outlet holes.

[0011] Furthermore, anti-slip blocks are fixedly installed at the bottom of the binding strap and at the top of the bracket.

[0012] This utility model has the following beneficial effects: After the fire extinguishing operation is completed, the foam gun is placed on two supports. Then, the binding straps on the top connecting rings of the two supports are threaded through the rotating rings. The binding straps are tightened so that the portion of the binding strap that does not pass through the rotating rings can adhere to the top of the foam gun. The binding straps are then tightened and adhered to the hook and loop fasteners. The portion of the binding strap that does not pass through the rotating rings adheres to the top of the foam gun, thus firmly fixing the foam gun to the two supports.

[0013] This invention involves a worker pulling one of two levers outwards. The lever causes a connected movable plate to slide along a guide rail. At this time, a rack at one end of the movable plate also moves, causing a rotating gear to rotate. The rack on the other side, driven by the rotating gear, causes the corresponding movable plate to slide synchronously along the guide rail. Simultaneously, the elastic element outside the lever compresses with the displacement of the movable plate, storing elastic potential energy. The movable plate causes the fixed rollers at both ends to move synchronously along the sliding groove. After the fire hose is placed in the hanging frame, the lever is released. Under the rebound force of the elastic element, both movable plates slide inwards, and the fixed rollers on both sides gradually approach each other, clamping the fire hose roll placed in the hanging frame.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0020] Please see Figures 1-6As shown, this utility model is a mobile foam fire extinguishing device, including a mobile vehicle 1, a foam liquid storage tank 2 installed on the top of the mobile vehicle 1, a proportioning mixer 3 installed on the top of the foam liquid storage tank 2, a bracket 4 symmetrically installed on one side of the top of the foam liquid storage tank 2, and foam guns 5 installed on the top of the two brackets 4. When a fire occurs, the operator pushes the mobile vehicle 1 to move the entire device to the fire scene. At this time, the foam liquid storage tank 2 contains foam liquid. After the device is started, the foam liquid is transported from the foam liquid storage tank 2 to the proportioning mixer 3 at the top. Under the action of the proportioning mixer 3, the foam liquid and the introduced water are fully mixed in a preset ratio to form a foam mixture with fire extinguishing effect. The mixed foam mixture is transported through the fire hose to the foam gun 5 installed on the bracket 4. The foam mixture is sprayed at the fire source to achieve fire extinguishing operation. This is the fire extinguishing process of the device.

[0021] The mobile vehicle 1 is symmetrically fixedly connected with fixed frames 6, and a hanging frame 7 is fixedly connected between the two fixed frames 6. A rotating gear 8 is rotatably installed at the center of one end of the hanging frame 7, and fixed mechanisms 9 are symmetrically meshed on both sides of the rotating gear 8. The fixed mechanisms 9 are slidably installed in the hanging frame 7. After the firefighting operation is completed, the spiral-shaped fire hose needs to be placed into the hanging frame 7. First, workers need to manually pull the fixing mechanism 9 away from the rotating gear 8. Either of the two fixing mechanisms 9 can be pulled; there are no restrictions. The pulled fixing mechanism 9 will cause the meshing rotating gear 8 to rotate on the hanging frame 7. Simultaneously, the rotation of the rotating gear 8 will cause the other fixing mechanism 9, which is meshed with the rotating gear 8, to move away from the pulled fixing mechanism 9. This increases the distance between the two fixing mechanisms 9 within the hanging frame 7, providing space for the fire hose. During the movement of the two fixing mechanisms 9, the compression of corresponding components inside the two fixing mechanisms 9 stores elastic potential energy. After the fire hose is placed inside the hanging frame 7, between the two fixing mechanisms 9, the fixing mechanisms 9 are then released. The two fixing mechanisms 9 will simultaneously move towards the fire hose due to the elastic release of their respective components, and at the same time drive the rotating gear 8 to rotate, thereby clamping and fixing both ends of the fire hose. In this way, the elastic potential energy of the corresponding components of the two fixing mechanisms 9 is used to clamp and fix the fire hose in the hanging frame 7, thereby preventing the fire hose roll from getting tangled or knotted inside the hanging frame 7 during movement. It should be noted that the two fixing mechanisms 9 can also accommodate fire hose rolls of different diameters. The larger the diameter of the fire hose roll, the greater the deformation of the two fixing mechanisms 9 when in contact with the outer wall of the fire hose roll, and the greater the clamping force generated.

[0022] A connecting ring 10 is fixedly installed on one side of the top of the bracket 4, and a rotating ring 11 is also rotatably connected to one side of the top of the bracket 4. A binding strap 12 is rotatably installed on the top of the connecting ring 10, and a hook and loop fastener surface 13 and a hook and loop fastener surface 14 are fixedly installed on one end of the binding strap 12.

[0023] After the fire extinguishing operation is completed, the foam gun 5 needs to be placed on the two supports 4. After the foam gun 5 is placed on the two supports 4, the binding straps 12 on the top connecting rings 10 of the two supports 4 are then threaded into the rotating rings 11. In order to allow the binding straps 12 to pass through or be pulled out of the rotating rings 11 more easily, the width of the binding straps 12 is 50% to 80% of the width of the rotating rings 11; the thickness is 10% to 50% of the thickness of the rotating rings 11; and the binding straps 12 are made of nylon. Then the binding straps 12 are tightened so that the portion of the binding straps 12 that does not pass through the rotating rings 11 is fitted against the top of the foam gun 5, and the binding straps 12 do not pass through the rotating rings 11. The part of the foam gun 5 is fitted with a Velcro surface 14; the part passing through the rotating ring 11 is fitted with a Velcro loop surface 13. It should be noted that the Velcro loop surface 13 can also be installed on the part of the cable tie 12 that does not pass through the rotating ring 11; the part passing through the rotating ring 11 is fitted with a Velcro surface 14, which is not limited here. Then, the cable tie 12 is tightened and the Velcro loop surface 13 and the Velcro surface 14 are attached together. The part of the cable tie 12 that does not pass through the rotating ring 11 will be attached to the surface of the foam gun 5, which will firmly fix the foam gun 5 to the two brackets 4. Thus, when the moving vehicle 1 is moving, the foam gun 5 can be stably placed in the position even when encountering uneven road conditions.

[0024] In one embodiment, the fixing mechanism 9 includes a movable plate 901, which is slidably connected to the hanging frame 7. Fixed rollers 902 are fixedly installed at both the upper and lower ends of the movable plate 901, and both fixed rollers 902 are located in the inner cavity of the hanging frame 7.

[0025] A rack 903 is fixedly installed at one end of the movable plate 901, and the rack 903 meshes with the rotating gear 8. A pull rod 904 is fixedly installed at the end of the movable plate 901 away from the rack 903, and the pull rod 904 is slidably installed on the fixed frame 6.

[0026] An elastic element 905 is sleeved on the outside of the pull rod 904. One end of the elastic element 905 is fixedly installed on the fixed frame 6, and the other end of the elastic element 905 away from the fixed frame 6 is fixedly installed on the movable plate 901.

[0027] The hanging frame 7 has a sliding groove for the fixed roller 902 to slide, and a guide rail for guiding the movable plate 901 is also fixedly installed on the hanging frame 7. When the fire hose wound into a spiral shape is placed into the hanging frame 7, the operator first needs to manually pull either of the two pull rods 904. The pull rod 904 will drive the movable plate 901, which is fixedly connected to it, to slide along the guide rail on the hanging frame 7. At this time, the rack 903 at one end of the movable plate 901 will move synchronously with the movable plate 901. Because the rack 903 meshes with the rotating gear 8, the rotating gear 8 will be driven to rotate. Since the racks 903 are symmetrically meshed on both sides of the rotating gear 8, the rack 903 on the other side will drive the corresponding movable plate 901 to slide synchronously along the guide rail under the drive of the rotating gear 8. If the pull rod 904 is pulled, the moving plate 901 will slide outward, and the moving plate 901 on the other side will also slide outward. When the moving plate 901 slides, the fixed rollers 902 at the upper and lower ends will move synchronously along the sliding groove on the hanging frame 7. At the same time, the elastic element 905 (preferably a spring) outside the pull rod 904 will be compressed with the displacement of the moving plate 901, storing elastic potential energy. Then, the fire hose is placed in the hanging frame 7 and the pull rod 904 is released. Under the rebound force of the elastic element 905, the moving plate 901 slides inward, and the moving plate 901 on the other side also slides inward. The fixed rollers 902 on both sides gradually approach each other and clamp the fire hose roll placed in the hanging frame 7, completing the fixing operation of the fire hose.

[0028] In one embodiment, the hanging frame 7 is provided with a plurality of water outlet holes 701 at its bottom.

[0029] Residual water that has not been completely drained after use flows out of the hanging frame 7 through the water outlet 701.

[0030] In one embodiment, for the aforementioned cable tie 12, anti-slip blocks 15 are fixedly installed at both the bottom of the cable tie 12 and the top of the bracket 4.

[0031] When the foam gun 5 is placed on the two supports 4, the rubber anti-slip blocks 15 on the top of the supports 4 will directly contact the bottom of the foam gun 5. The rubber material has a large coefficient of friction and is relatively soft, which can better fit the bottom of the foam gun 5, thereby increasing the friction between the supports 4 and the bottom of the foam gun 5. When the cable tie 12 is used to fix the foam gun 5, after the cable tie 12 passes through the rotating ring 11 and is tightened, the rubber anti-slip blocks 15 on the bottom of the cable tie 12 will fit tightly against the top of the foam gun 5. Similarly, the anti-slip blocks 15 can increase the friction between the cable tie 12 and the top of the foam gun 5. The two rubber anti-slip blocks 15 work together to effectively prevent the foam gun 5 from sliding back and forth when the moving vehicle 1 is moving.

[0032] Working principle: When the operator pulls either of the two levers 904 outwards, the lever 904 causes the connected movable plate 901 to slide along the guide rail. At this time, the rack 903 at one end of the movable plate 901 also moves, which in turn causes the rotating gear 8 to rotate. Then, the rack 903 on the other side will drive the corresponding movable plate 901 to slide synchronously along the guide rail under the drive of the rotating gear 8. At the same time, the elastic element 905 outside the lever 904 will be compressed with the displacement of the movable plate 901, storing elastic potential energy. The movable plate 901 drives the fixed rollers 902 at both ends to move synchronously along the sliding groove. After the fire hose is placed in the hanging frame 7, the lever 904 is released. Under the rebound force of the elastic element 905, both movable plates 901 slide inwards, and the fixed rollers 902 on both sides gradually approach each other, clamping the fire hose roll placed in the hanging frame 7. After the fire extinguishing operation is completed, the foam gun 5 is placed on the two supports 4. Then, the binding straps 12 on the top connecting rings 10 of the two supports 4 are threaded through the rotating rings 11. The binding straps 12 are tightened so that the part of the binding straps 12 that does not pass through the rotating rings 11 can be attached to the top of the foam gun 5. Then, the binding straps 12 are tightened and attached to the Velcro surface 13 and Velcro surface 14. The part of the binding straps 12 that does not pass through the rotating rings 11 is attached to the top of the foam gun 5, and the foam gun 5 is firmly fixed to the two supports 4. Anti-slip blocks 15 are fixedly installed at the bottom of the binding straps 12 and the top of the supports 4 to prevent the foam gun 5 from sliding back and forth.
