Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a tank top foam generator with a protective structure. Background Art

[0002] Air foam generator is a common fire-fighting equipment that extinguishes oil fires by generating and spraying air foam. It is usually installed on the top of oil storage tanks.

[0003] Currently, the common tank top foam generators on the market are mostly similar in structure. There are nozzles and sealing glass inside the shell, and a porous air inlet plate on the outside of the shell. The shell is connected to the tank through a nozzle. When a fire occurs, the fixed fire pump is turned on, and the fire pump sprays the high-pressure mixed liquid through the nozzle to the nozzle. The high-pressure mixed liquid breaks through the sealing glass and enters the tank along the nozzle. The external air enters the nozzle through the holes inside the air inlet plate at the same time to help the high-pressure mixed liquid foam. There are some functional deficiencies in actual use and there is room for improvement. For example, the foam generator is mostly installed on the top of the tank, and its shell is exposed to the outside, while the interior is mainly sealed by the sealing glass. When the shell encounters hail weather, the shell is hit, and the internal sealing glass itself has scratches on the surface to make it easy to break, and its impact resistance is weak. It is easy to cause the internal glass to shatter under the impact of hail, and oil and gas will leak. The internal sealing glass itself is also more troublesome to replace and does not have the function of top protection.

[0004] Now, a new tank top foam generator with a protective structure is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a tank top foam generator with a protective structure to solve the problem of the lack of top protection function proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a tank top foam generator with a protective structure, comprising a main shell, an air inlet plate fixedly connected to the bottom end of the main shell, a nozzle fixedly connected to the right side inside the main shell, a conducting pipe provided on the left side of the main shell, a sub-shell fixedly connected to the outside of the conducting pipe, a nozzle fixedly connected to the left side of the conducting pipe, and a protective component for protecting the main body provided on the left side of the top of the main shell.

[0007] The protective component includes an internal thread fixing seat, which is fixedly connected to the left side of the top of the main shell body. An external thread fixing rod is vertically inserted into the interior of the internal thread fixing seat. A swivel is fixedly connected to the outside of the external thread fixing rod. A dome cover is provided above the external thread fixing rod. A shock-absorbing spring is provided between the top end of the external thread fixing rod and the bottom end of the dome cover.

[0008] Preferably, the outer diameter of the externally threaded fixing rod is consistent with the inner diameter of the internally threaded fixing seat, and the outer threads of the externally threaded fixing rod are consistent with the inner threads of the internally threaded fixing seat.

[0009] Preferably, the vertical center lines of the internal thread fixing seat, the external thread fixing rod, the swivel and the dome cover coincide with each other, and the exterior of the swivel is machined with vertical lines.

[0010] Preferably, the top end of the shock-absorbing spring is connected to the middle position of the bottom end of the dome cover plate, and the bottom end of the shock-absorbing spring is connected to the top end of the externally threaded fixing rod.

[0011] Preferably, a positioning ring is fixedly connected to the right side of the auxiliary shell, an external threaded interface is welded to the right side of the positioning ring, an internal threaded cover is sleeved on the right side of the outside of the guiding tube, a through groove is provided on the right side of the internal threaded cover, a sealing glass is provided on the right side of the inside of the internal threaded cover, a first sealing ring is glued to the right side of the sealing glass, and a second sealing ring is glued to the left side of the sealing glass.

[0012] Preferably, the external thread of the external thread interface matches the internal thread of the main shell, the internal thread of the internal thread cover matches the external thread of the guide tube, and the side of the sealing glass near the nozzle is scored.

[0013] Preferably, an internally threaded tube seat is fixedly connected to the right side of the top of the main shell, a gas sensor is vertically inserted into the internally threaded tube seat, a mounting ring is fixedly connected to the outside of the gas sensor, and a sensor terminal is provided at the top of the gas sensor.

[0014] Preferably, the external threads of the gas sensor match the internal threads of the internally threaded tube seat, and the bottom end of the gas sensor passes through the interior of the internally threaded tube seat and extends into the interior of the main housing.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the tank top foam generator with a protective structure not only realizes the function of top protection, but also realizes the function of easy replacement of internal glass and the function of feedback of glass breakage;

[0016] (1) The nozzle and the storage tank are connected by providing an internal thread fixing seat, an external thread fixing rod, a rotating ring, a dome cover plate and a shock-absorbing spring. The right side of the main shell is connected to the fire pump through a pipeline. When a fire occurs, the fire pump is turned on, and the high-pressure mixed liquid is sprayed along the nozzle to the sealed glass. After the sealed glass is shattered, it quickly flows into the storage tank along the nozzle. Driven by the high-pressure mixed liquid jet, the external air enters the storage tank together with the mixed liquid through the air inlet plate, which facilitates the foaming of the mixed liquid. When installing the foamer, the external thread fixing rod at the bottom of the dome cover plate is screwed into the internal thread fixing seat at the top of the main shell. The rotating ring facilitates rotation and force generation. The dome cover plate is blocked on the top of the main shell. When extreme weather such as hail is about to occur, the dome cover plate can block the high-speed falling hail. The shock-absorbing spring retracts and swings to reduce the vibration caused by the impact, reducing the chance of the sealed glass being shattered by the vibration. At the same time, the dome cover plate can also play the role of sunshade and rain protection, avoiding the sealing glass from bursting due to high temperature and the air inlet plate holes from being sealed due to freezing rain, thereby achieving the function of top protection.

[0017] (2) By providing a positioning ring, an external thread interface, an internal thread cover, a through groove, a first sealing ring, a sealing glass and a second sealing ring, when the sealing glass needs to be replaced, the main shell and the pipeline are separated, and the main shell is rotated to directly unscrew it from the external thread interface, and then the internal thread cover is rotated to unscrew it from the conducting pipe, and the broken sealing glass fragments inside are removed, and a new sealing glass is taken and filled into the internal thread cover. As the internal thread cover is screwed back onto the conducting pipe, the second sealing ring on the left side of the sealing glass is tightly attached to the conducting pipe, and the first sealing ring on the right side of the sealing glass is tightly attached to the inside of the internal thread cover, thereby ensuring the sealing performance. The through groove facilitates the passage of the high-pressure mixed liquid, thereby realizing the function of easy replacement of the internal glass;

[0018] (3) By providing an internal threaded tube holder, a gas sensor, a mounting ring and a sensor terminal head, the glass sealing conducting tube is sealed to prevent oil and gas leakage. When the conducting tube is damaged and oil and gas leaks, the gas sensor can quickly capture the gas leakage signal and feed it back to the control center through the wiring at the end of the sensor terminal head, which is convenient for operation and maintenance personnel to quickly inspect and repair and avoid further leakage of oil and gas. The internal threaded tube holder and the mounting ring facilitate the disassembly and assembly of the gas sensor, realizing the function of glass breakage feedback.

[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 A tank top foam generator with a protective structure also includes a protective assembly, which includes an internal thread fixing seat 7, which is fixedly connected to the left side of the top of the main shell 1, an external thread fixing rod 8 is vertically inserted into the internal part of the internal thread fixing seat 7, and a swivel 9 is fixedly connected to the outside of the external thread fixing rod 8. A dome cover plate 10 is provided above the external thread fixing rod 8, and a shock-absorbing spring 11 is provided between the top end of the external thread fixing rod 8 and the bottom end of the dome cover plate 10;

[0027] The outer diameter of the external thread fixing rod 8 is consistent with the inner diameter of the internal thread fixing seat 7. The external thread of the external thread fixing rod 8 is consistent with the internal thread of the internal thread fixing seat 7. The vertical center lines of the internal thread fixing seat 7, the external thread fixing rod 8, the swivel 9, and the dome cover 10 coincide with each other. The outer surface of the swivel 9 is machined with vertical lines. The top of the shock-absorbing spring 11 is connected to the middle position of the bottom end of the dome cover 10. The bottom end of the shock-absorbing spring 11 is connected to the top of the external thread fixing rod 8, which can protect the top and reduce the chance of glass shattering.

[0028] Specifically, if Figure 1 and Figure 3 As shown, the external thread fixing rod 8 at the bottom of the dome cover 10 is screwed into the internal thread fixing seat 7 at the top of the main shell 1, and the swivel 9 is convenient for rotating and exerting force. The dome cover 10 is blocked on the top of the main shell 1. When extreme weather such as hail is about to occur, the dome cover 10 can block the hail falling at high speed, and the shock-absorbing spring 11 retracts and swings to reduce the vibration caused by the impact, thereby reducing the chance of the sealing glass 17 being shattered by the vibration. At the same time, the dome cover 10 can also play the role of sunshade and rain protection, thereby avoiding the sealing glass 17 from bursting due to high temperature and the holes of the air inlet plate 2 from being sealed due to freezing rain.

[0029] Embodiment 2: The right side of the auxiliary shell 4 is fixedly connected with a positioning ring 12, and the right side of the positioning ring 12 is welded with an external thread interface 13, the right side of the outside of the guide tube 5 is sleeved with an internal thread cover 14, the right side of the internal thread cover 14 is provided with a through groove 15, and the right side of the inside of the internal thread cover 14 is provided with a sealing glass 17. The right side of the sealing glass 17 is glued with a first sealing ring 16, and the left side of the sealing glass 17 is glued with a second sealing ring 18. The external thread of the external thread interface 13 is consistent with the internal thread of the main shell 1, and the internal thread of the internal thread cover 14 is consistent with the external thread of the guide tube 5. The side of the sealing glass 17 near the nozzle 3 is scored to facilitate the replacement of the internal glass;

[0030] Specifically, if Figure 2 and Figure 4 As shown, rotate the main shell 1 to unscrew it directly from the external thread interface 13, then rotate the internal thread cover 14 to unscrew it from the conducting tube 5, remove the broken pieces of sealing glass 17 inside, take out new sealing glass 17, and fill it into the internal thread cover 14. As the internal thread cover 14 is screwed back onto the conducting tube 5, the second sealing ring 18 on the left side of the sealing glass 17 is tightly against the conducting tube 5, and the first sealing ring 16 on the right side of the sealing glass 17 is tightly against the inside of the internal thread cover 14 to ensure the sealing performance.

[0031] Example 3: An internally threaded tube socket 19 is fixedly connected to the right side of the top of the main housing 1. A gas sensor 20 is vertically inserted into the internally threaded tube socket 19. A mounting ring 21 is fixedly connected to the outside of the gas sensor 20. A sensor terminal 22 is provided on the top of the gas sensor 20. The external threads of the gas sensor 20 match the internal threads of the internally threaded tube socket 19. The bottom end of the gas sensor 20 passes through the interior of the internally threaded tube socket 19 and extends into the interior of the main housing 1, which can provide timely feedback when the glass is broken.

[0032] Specifically, if Figure 1 and Figure 2As shown, the gas sensor 20 can quickly capture the signal of gas leakage and feed it back to the control center through the wiring at the end of the sensor terminal 22, which is convenient for operation and maintenance personnel to quickly inspect and repair and avoid further leakage of oil and gas. The internal threaded pipe seat 19 and the mounting ring 21 facilitate the disassembly and assembly of the gas sensor 20.

[0033] Working principle: When the utility model is in use, first, the nozzle 6 is connected to the storage tank, and the right side of the main shell 1 is connected to the fire pump through a pipeline. When a fire occurs, the fire pump is turned on, and the high-pressure mixed liquid is sprayed along the nozzle 3 to the sealing glass 17. After the sealing glass 17 is broken, it quickly flows into the storage tank along the nozzle 6. Driven by the high-pressure mixed liquid jet, the external air enters the storage tank together with the mixed liquid through the air inlet plate 2, which facilitates the foaming of the mixed liquid. When installing the foamer, fix the external thread at the bottom of the dome cover plate 10 The rod 8 is screwed into the internal thread fixing seat 7 on the top of the main shell 1, and the swivel 9 is convenient for rotating and exerting force. The dome cover 10 blocks the top of the main shell 1. When there is extreme weather such as hail, the dome cover 10 can block the hail falling at high speed. The shock-absorbing spring 11 retracts and swings to reduce the vibration caused by the impact, and reduces the chance of the sealed glass 17 being shattered by the vibration. At the same time, the dome cover 10 can also play the role of sunshade and rain protection, avoiding the sealing glass 17 from bursting due to high temperature and the holes of the air intake plate 2 from being sealed due to freezing rain. When replacing the sealing glass 17, separate the main housing 1 from the pipe and rotate the main housing 1 to remove it directly from the external threaded interface 13. Then, rotate the internally threaded cover 14 to remove it from the conducting tube 5. Remove the broken pieces of sealing glass 17, take a new piece of sealing glass 17, and insert it into the internally threaded cover 14. As the internally threaded cover 14 is screwed back onto the conducting tube 5, the second sealing ring 18 on the left side of the sealing glass 17 abuts against the conducting tube 5, and the first sealing ring 16 on the right side of the sealing glass 17 abuts against the inside of the internally threaded cover 14, ensuring a tight seal. The through groove 15 facilitates the passage of the high-pressure mixed liquid. The sealing glass 17 seals the conducting tube 5, preventing oil and gas leakage. If the conducting tube 5 is damaged and leaking, the gas sensor 20 can quickly detect the gas leak signal and send it back to the control center through the wiring at the end of the sensor connector 22, facilitating quick inspection and maintenance by operators to prevent further oil and gas leakage. The internally threaded tube socket 19 and mounting ring 21 facilitate the disassembly and assembly of the gas sensor 20.
