[0015] By adopting the technical scheme, when the staff rotates the rotating rod, the annular block rotates synchronously with the rotating rod under the action of the rotating rod, in the process, the annular block limits the rotating rod, thereby reducing the probability of sliding of the rotating rod, and thus the stability of the device is improved.

DETAILED DESCRIPTION
[0029] With reference to the accompanying drawings: obvious, the described embodiments are only part of the embodiments of the present application, and not all embodiments, based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor belong to the scope of protection of the present application.
[0030] As shown in Figures 1-3 The foam spray pipe assembly disclosed by the present application comprises a water pipe 1, a shell 11, a spray pipe 12, a blocking plate 13, a sliding rod 14, a rotating rod 3, a fixed block 31, a first electromagnet 4, a second electromagnet 41, a first spring 5, a rotating rod 6, a I-shaped wheel 61, a fixed rope 62, a ring-shaped block 7, a circular block 8 and a torsional spring 81. The water pipe 1 is a circular pipe structure, and its axis is horizontal. The shell 11 is a hollow cylindrical structure, and its axis coincides with the axis of the water pipe 1. The spray pipe 12 is arranged at the end of the shell 11 away from the water pipe 1, and its axis coincides with the axis of the water pipe 1. A sliding groove 2 is formed in the inner wall of the spray pipe 12. The blocking plate 13 is a circular plate structure, and its axis coincides with the axis of the spray pipe 12. The blocking plate 13 is rotationally arranged on the inner wall of the spray pipe 12, and a limiting slot is formed in the outer wall of the blocking plate 13. The sliding rod 14 is a circular rod structure, and the sliding rod 14 is slidingly arranged in the sliding groove 2 and slidingly connected with the limiting slot.
[0031] When a fire occurs, the fire alarm at the fire scene triggers, the water pipe 1 opens, and then the foam fire extinguishing material in the water pipe 1 is sprayed out. At this time, the staff needs to slide the sliding rod 14, and then slide the sliding rod 14 into the sliding groove 2 to separate the sliding rod 14 from the limiting slot, so that the blocking plate 13 rotates, and then the foam fire extinguishing material enters the spray pipe 12. Subsequently, the spray pipe 12 sprays out to extinguish the fire at the fire scene. In this process, the limiting plate cannot be rotated. In addition, after the fire is extinguished, the staff can reset the blocking plate 13 by sliding one end of the sliding rod 14 into the limiting slot, thereby improving the practicability of the device.
[0032] A rotating groove 22 is formed in the inner wall of the sliding groove 2. The rotating rod 3 is a circular rod structure, and its axis is horizontal. The rotating rod 3 is rotationally arranged in the rotating groove 22, and the rotating rod 3 is fixed with the sliding rod 14.
[0033] A fixed groove 23 is formed in the inner top wall of the rotating groove 22. An installation groove 24 is formed in the outer wall of the rotating rod 3. The fixed block 31 is a rectangular block structure, and the fixed block 31 is slidingly arranged in the fixed groove 23 and slidingly connected with the installation groove 24.
[0034] The first electromagnet 4 is fixedly arranged on the inner top wall of the fixed groove 23. The second electromagnet 41 is fixedly arranged on the upper surface of the fixed block 31. The first electromagnet 4 and the second electromagnet 41 are attracted to each other.
[0035] One end of the first spring 5 is fixedly mounted on the inner wall of the rotating groove 22, and the other end of the first spring 5 abuts against the side wall of the rotating rod 3 away from the slide rod 14.
[0036] When the fire alarm is triggered, the controller connected to the fire alarm receives a signal, which in turn energizes the first electromagnet 4 and the second electromagnet 41. This causes the first electromagnet 4 and the second electromagnet 41 to attract each other, causing the fixing block 31 to slide upwards under the action of the first electromagnet 4 and the second electromagnet 41, thus separating the fixing block 31 from the mounting groove 24. At this time, the rotating rod 3 slides towards the slide groove 2 under the action of the first spring 5, causing the slide rod 14 to slide into the slide groove 2 and separate from the limiting groove under the action of the rotating rod 3. During this process, there is no need for the operator to manually slide the slide rod 14, thus reducing the difficulty of the operator's work. Furthermore, when the baffle plate 13 rotates, the rotating rod 3 rotates under the action of the baffle plate 13. During this process, the rotating rod 3 limits the movement of the baffle plate 13, thus reducing the probability of the baffle plate 13 shaking and improving the stability of the device.
[0037] A rotating groove 25 is formed on the outer wall of the nozzle 12, and a receiving groove 26 is formed on the inner wall of the rotating groove 25. The rotating rod 6 is a round rod structure, and its axis coincides with the axis of the rotating rod 3. The I-shaped wheel 61 is fixedly mounted on the side wall of the rotating rod 6, and its axis coincides with the axis of the rotating rod 6. One end of the fixing rope 62 is wrapped around the outer wall of the I-shaped wheel 61, and the end of the fixing rope 62 away from the I-shaped wheel 61 passes through the receiving groove 26 and is fixed to the side wall of the rotating rod 3 away from the slide bar 14.
[0038] After the fire is extinguished, workers need to rotate the baffle plate 13 so that the slide 2 is aligned with the limiting groove. At this time, workers need to rotate the rotating rod 6, which causes the I-shaped wheel 61 to rotate under the action of the rotating rod 6. This causes one end of the fixing rope 62 to wrap around the outer wall of the I-shaped wheel 61, and the other end of the fixing rope 62 to slide away from the slide 2. This causes the rotating rod 3 and the sliding rod 14 to slide away from the slide 2 under the action of the fixing rope 62, and one end of the sliding rod 14 to slide into the limiting groove, thereby fixing the baffle plate 13. This reduces the difficulty for workers to reset the baffle plate 13 and reduces the difficulty of the work.
[0039] An annular groove 27 is provided on the inner wall of the rotating groove 25. The annular block 7 is rotatably disposed in the annular groove 27, and its axis coincides with the axis of the rotating rod 6. The annular block 7 and the rotating rod 6 are fixed to each other.
[0040] When the operator rotates the rotating rod 6, the annular block 7 rotates synchronously with the rotating rod 6 under its action. During this process, the annular block 7 limits the rotation of the rotating rod 6, thereby reducing the probability of the rotating rod 6 slipping and improving the stability of the device.
[0041] A circular groove 28 is formed on the inner wall of the rotating groove 22. A circular block 8 is fitted onto the outer wall of the rotating rod 3, with its axis coinciding with the axis of the rotating rod 3. The circular block 8 is rotatably connected to the circular groove 28. One end of the torsion spring 81 is fitted onto the outer wall of the rotating rod 3, and one end of the torsion spring 81 is fixed to the side wall of the circular plate. The other end of the torsion spring 81 is fixed to the inner wall of the circular groove 28.
[0042] A connecting groove 29 is provided on the outer wall of the rotating rod 3, and the connecting block 9 is slidably disposed in the connecting groove 29. The connecting block 9 and the circular block 8 are fixed to each other.
[0043] When the rotating rod 3 slides, the connecting block 9 slides relative to the connecting groove 29. Subsequently, when the rotating rod 3 rotates, the circular block 8 rotates under the action of the rotating rod 3 due to the connecting block 9, thereby compressing the torsion spring 81. After the fire is extinguished, the water pipe 1 stops working, causing the circular block 8 to rotate in the opposite direction under the action of the torsion spring 81, thus causing the rotating rod 3 to rotate in the opposite direction under the action of the circular block 8. During this process, there is no need for the staff to manually rotate the blocking plate 13, thereby reducing the difficulty of the work for the staff.
[0044] To improve the practicality of the device, the nozzle 12 has a built-in power supply. The first electromagnet 4 and the second electromagnet 41 are electrically connected to the power supply. The built-in power supply in the nozzle 12 eliminates the need for external power sources for the first electromagnet 4 and the second electromagnet 41, thus improving the device's usability.
[0045] In this embodiment, the foam nozzle assembly operates as follows: When a fire occurs, the fire alarm at the fire scene is triggered, water pipe 1 opens, and the foam extinguishing material inside water pipe 1 is sprayed out. At this time, the controller connected to the fire alarm receives a signal, which energizes the first electromagnet 4 and the second electromagnet 41, causing them to attract each other. This causes the fixing block 31 to slide upward under the action of the first and second electromagnets 4 and 41, thus separating the fixing block 31 from the mounting groove 24. Then, the rotating rod 3 slides towards the slide groove 2 under the action of the first spring 5, causing the sliding rod 14 to slide into the slide groove 2 and separate from the limiting groove. This causes the baffle plate 13 to move under the action of the sprayed foam extinguishing material, allowing the foam extinguishing material to enter the nozzle 12. Subsequently, the foam extinguishing material is sprayed out from the nozzle 12 to extinguish the fire at the scene. After the fire is extinguished, water pipe 1 stops working, causing circular block 8 to rotate in the opposite direction under the action of torsion spring 81. This causes rotating rod 3 to rotate in the opposite direction under the action of circular block 8, which in turn causes the baffle to rotate in the opposite direction under the action of rotating rod 3, thus aligning slide 2 with the limiting groove. At this time, the worker needs to rotate rotating rod 6, causing I-shaped wheel 61 to rotate under the action of rotating rod 6. This causes one end of fixing rope 62 to wrap around the outer wall of I-shaped wheel 61, and the other end of fixing rope 62 to slide away from slide 2. This causes rotating rod 3 and slide rod 14 to slide away from slide 2 under the action of fixing rope 62, and one end of slide rod 14 to slide into the limiting groove, thereby fixing the baffle plate 13.

All technical solutions falling within the scope of this utility model's concept are protected by this utility model.
