Description
Technical Field
[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a vertical air foam generator suitable for various situations. Background Art
[0002] An air foam generator is a fire-fighting device that extinguishes fires by spraying air foam. Since the severity of each fire is different, it is difficult to effectively extinguish a fire using an air foam generator alone. This requires the air foam generator to adjust the amount of foam liquid sprayed by the equipment according to the actual situation, so that the equipment can continue to spray a small amount of foam liquid, allowing the equipment to control the scope of the fire before firefighters arrive at the scene. This requires the use of a vertical air foam generator that is suitable for a variety of situations.
[0003] Patent document CN204972791U discloses a vertical air foam generator suitable for a variety of situations, "including a shell, a connecting pipe, a connecting hole is provided in the middle of the bottom of the shell, the upper end of the connecting pipe extends from the connecting hole from bottom to top into the shell, the upper open end of the connecting pipe is located above the middle of the shell, a spray port is provided below the axial middle of the shell, an outer flange connecting plate is provided on the outside of the spray port, a drain valve is provided near the outside of the bottom of the shell, the lower end of the connecting pipe is connected to the inlet flange, the connecting pipe is provided with a porous plate near the lower end, a plurality of rows of air inlet holes are provided on the porous plate, the air inlet holes are connected to the inner cavity of the connecting pipe, the inlet flange is provided with a bolt connection hole near the outer edge, the outer end face of the inlet flange is provided with a boss, and the boss is connected to the external flange surface. The utility model has light weight, reliable sealing connection, convenient installation and disassembly, low processing and maintenance costs, and can ensure the stability and reliability of the long-term operation of the air foam generator. "
[0004] The above-mentioned equipment has a relatively simple structure, which allows it to be disassembled and assembled, thereby facilitating subsequent maintenance, and the materials used are relatively common, thereby reducing the production cost of the equipment. Due to the different severity of the fire, it is difficult to effectively extinguish the fire by relying solely on the equipment, which requires the equipment to adjust the amount of foam liquid sprayed by the equipment according to the actual situation, so that the equipment can limit the fire in a continuous and small amount. However, it is difficult for the equipment to adapt to the fire situation through adjustment, which can easily lead to the sprayed foam liquid not only being difficult to extinguish the fire, but also causing waste of foam liquid, which requires staff to improve their equipment.

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0026] See also Figure 1 , Figure 3 and Figure 5 A vertical air foam generator suitable for various situations: a T-tube 1, both ends of the T-tube 1 are fixedly connected with connecting tubes 2, one end of the connecting tube 2 is fixedly connected with a first transport pipe 3, both sides of the first transport pipe 3 are fixedly connected with connecting plates 4, the inner wall of the first transport pipe 3 is provided with a first water pump 5, one side of the first transport pipe 3 is provided with a rotating groove 6, the inner wall of the rotating groove 6 is rotatably connected with a connecting frame 7, the top of the connecting frame 7 is fixedly connected with a handle 8, the inner wall of the connecting frame 7 is provided with a water delivery groove 9, and one side of the inner wall of the first transport pipe 3 is fixedly connected with a limiting plate 21.
[0027] When the equipment is used for firefighting, the foam liquid in the T-tube 1 passes through the connecting tube 2 and generates foam after contacting with the air. The foam liquid is then transported to the first transport pipe 3 by the first water pump 5, and then transported to the spray structure after being transported through the first transport pipe 3 to carry out firefighting spraying. When spraying, the handle 8 can be held to rotate the connecting frame 7 so that the connecting frame 7 rotates in the rotating groove 6. When the connecting frame 7 rotates, due to the different sizes of the water delivery grooves 9 opened in the connecting frame 7, the limiting plate 21 set on one side of the inner wall of the first transport pipe 3 can just cover half of the connecting frame 7, which makes the rotation of the connecting frame 7 adjust the flow rate of the foam liquid passing through the water delivery groove 9, thereby achieving the adjustment of the spraying amount of the equipment. When encountering a fire that the equipment can extinguish, the connecting frame 7 can be rotated to adjust the flow rate of the equipment to the maximum for fire extinguishing. When the equipment encounters a fire that is difficult to extinguish, the equipment can be adjusted to an appropriate flow rate. By continuous small-scale spraying, a fireproof layer is formed at the fire scene, thereby preventing the fire from further deteriorating.
[0028] See also Figure 1 and Figure 2 A vertical air foam generator suitable for various situations: a valve 10 is arranged on the inner wall of a T-shaped tube 1, a connecting tube 11 is rotatably connected to the bottom of the T-shaped tube 1, a mounting base 12 is fixedly connected to the bottom end of the connecting tube 11, a second water pump 13 is arranged on the inner wall of the connecting tube 11, a sealing ring 14 is fixedly connected to the top of the connecting tube 11, and the top of the sealing ring 14 overlaps the bottom of the T-shaped tube 1.
[0029] Before using the equipment, first fix the mounting base 12 to the work site, connect the connecting pipe 11 to the foam liquid, pump the foam liquid into the connecting pipe 11 through the second water pump 13, and then transport it to the T-tube 1, open the valve 10, so that the foam liquid can be sprayed on both sides of the equipment through the T-tube 1. When the equipment is required to spray in multiple directions, the staff pushes the T-tube 1 to rotate, so that the rotation of the T-tube 1 drives the spraying structures on both sides to move around the axis of the connecting pipe 11, so that the equipment rotates and sprays.
[0030] See also Figure 1 , Figure 3 and Figure 4 A vertical air foam generator suitable for various situations: screens 15 are fixedly connected to both sides of a connecting tube 2, baffles 16 are fixedly connected to the tops of both sides of the connecting tube 2, a glass plate 17 is overlapped on one side of the inner wall of the connecting tube 2, a limiting tube 18 is slidably connected to one side of the inner wall of the connecting tube 2, and one side of the limiting tube 18 is overlapped on one side of the glass plate 17, a second transport pipe 19 is fixedly connected to one side of the connecting plate 4, and a nozzle 20 is fixedly connected to one side of the second transport pipe 19.
[0031] The foam liquid is transported to the openings on both sides by the second water pump 13, and the glass plate 17 is broken by the impact force generated by the flow of the foam liquid. Since the surface of the glass plate 17 is provided with grooves, the glass plate 17 is relatively easy to break. When flowing in the connecting tube 2, air enters the connecting tube 2 through the screen 15. The air enters the connecting tube 2 and contacts with the foam liquid, so that the foam liquid generates foam. The foam liquid then enters the first transport pipe 3 through the connecting tube 2, and then enters the second transport pipe 19 through the first water pump 5, and finally is sprayed out through the nozzle 20 on one side of the second transport pipe 19, so as to spray and extinguish the fire.
[0032] Working principle: first install the mounting base 12 at the work site, connect the foam liquid to the connecting pipe 11, pump it into the connecting pipe 11 through the second water pump 13, then open the valve 10, and then spray it to both sides through the T-tube 1. During the spraying process, it enters the first transport pipe 3 through the connecting tube 2, and comes into contact with the air at the connecting tube 2 to make the foam liquid generate foam. After the foam-generated foam liquid enters the first transport pipe 3, it is transported to the second transport pipe 19 through the first water pump 5, and finally sprayed out through the nozzle 20 on one side for spraying.
