Description

Technical Field

[0001] This utility model belongs to the field of fire fighting technology, and specifically relates to a fire fighting water cannon spraying device. Background Art

[0002] A fire fighting water cannon is a professional equipment for extinguishing fires, usually installed on a water cannon vehicle or other fire fighting vehicles. It mainly sprays water to the fire scene through high-pressure water flow to reduce the fire, cool the burning objects, and create conditions for rescue personnel. A fire fighting water cannon usually consists of parts such as a water source, a water pump, a control device, and a water spraying device.

[0003] At present, the nozzles of the fire fighting water cannons used can be selected according to the rescue needs. Commonly used ones generally include fixed nozzles, adjustable nozzles, rotary nozzles, foam nozzles, etc. When replacing and connecting the existing nozzles, most of them are connected in forms such as threads, bolts, or clamps. Although the connection purpose can be achieved, the operation is more troublesome during the replacement process, and the joint and the water pipe need to be accurately positioned to be fixed. Moreover, during the rescue process, it is also prone to looseness and detachment due to the high impact force of the water flow, thereby reducing its use stability and convenience. Content of the Utility Model

A joint is assembled at the other end of the second movable pipe. A baffle is fixedly connected to the side wall of the joint. A docking pipe is fixedly connected to the side wall of the baffle close to the second movable pipe. A locking cylinder is assembled on the side wall of the second movable pipe. An annular plate is movably connected to the end face of the locking cylinder. A clamping component is arranged on the side wall of the annular plate.

[0007] The clamping component includes a plurality of grooves opened on the side wall of the annular plate. Hooks are arranged in the grooves. A rotating shaft is fixedly connected to the side wall of the hook. The other end of the rotating shaft is rotatably connected to the side wall of the groove. A torsion spring is assembled on the side wall of the rotating shaft. A triangular block is fixedly connected to the side wall of the docking pipe. The triangular block is annular. The hook is adapted to the triangular block. Pulling ropes are fixedly connected to the side walls of the hooks.

[0021] To make the purpose and advantages of this utility model clearer, the following specifically describes this utility model in combination with embodiments. It should be understood that the following text only describes one or several specific implementation manners of this utility model and does not strictly limit the scope of protection of the specific claims of this utility model.

[0022] As Figures 1 - 5 shown, a fire water cannon spraying device includes a connecting seat 1. A first movable pipe 2 is movably connected to the connecting seat 1. The other end of the first movable pipe 2 is rotatably connected to a second movable pipe 3. Handles are respectively assembled on the side walls of the first movable pipe 2 and the second movable pipe 3. A connector 4 is assembled at the other end of the second movable pipe 3. A baffle 5 is fixedly connected to the side wall of the connector 4. A butt joint pipe 6 is fixedly connected to the side wall of the baffle 5 close to the second movable pipe 3. A locking cylinder 8 is assembled on the side wall of the second movable pipe 3. An annular plate 9 is movably connected to the end face of the locking cylinder 8. A clamping component is arranged on the side wall of the annular plate 9.

[0023] As Figure 2 and Figure 5 shown, the clamping component includes a plurality of grooves 10 opened on the side wall of the annular plate 9. Hooks 11 are arranged in the grooves 10. A rotating shaft 12 is fixedly connected to the side wall of the hook 11. The other end of the rotating shaft 12 is rotatably connected to the side wall of the groove 10. A torsion spring 13 is assembled on the side wall of the rotating shaft 12. A triangular block 7 is fixedly connected to the side wall of the butt joint pipe 6. The triangular block 7 is annular. The hook 11 is adapted to the triangular block 7. Pulling ropes 17 are fixedly connected to the side walls of the hooks 11. The other ends of the pulling ropes 17 penetrate through the annular plate 9 and are connected to each other.

[0024] A sealing ring 14 is fixedly connected to the side wall of the baffle 5. A sealing groove 15 is opened on the end face of the second movable pipe 3. The sealing ring 14 is adapted to the sealing groove 15. The sealing ring 14 is made of a corrosion-resistant and high-pressure-resistant flexible material. When tightened by the locking cylinder 8, the sealing ring 14 deforms under force and can closely fit in the sealing groove 15.

[0025] Specifically, when the connector 4 is caught on one side of the hook 11, at this time, the baffle 5 is closely attached to the end face of the second movable pipe 3. At the same time, the sealing ring 14 also catches in the sealing groove 15. Used in cooperation with the locking cylinder 8, it can further tighten the stability and sealing performance of the connector 4, and there will be no water leakage and loosening phenomena during use; and the rotation mode of controlling the locking cylinder 8 can adopt a manual wrench, an electric wrench or other tools.

[0026] As Figure 2 shown, a guard plate 16 is fixedly connected to the side wall of the baffle 5. The guard plate 16 is annular. By arranging the guard plate 16, the phenomenon of water flow contacting the clamping component can be reduced, and problems such as corrosion and rust of the structure of the clamping component caused by water flow during long-term use, which affect its structural strength, can be avoided.

[0027] As Figure 2As shown, the side wall of the second movable tube 3 is provided with threads, and the locking cylinder 8 is threadedly connected to the second movable tube 3. The threaded connection method is simple to operate, convenient in processing, and low in maintenance cost, and has a self-locking effect when used for secondary locking.

[0028] like Figure 3 As shown, the end face of the locking cylinder 8 is hexagonal. The locking cylinder 8 can be driven to rotate by an external tool, and its shape is not limited to this solution, and can also be a triangular deformation, a quadrilateral, a pentagon or other shapes.

[0029] The working principle of the utility model is as follows: when the connector 4 needs to be replaced, the locking cylinder 8 is first rotated to drive the hook 11 to move to the right through the annular plate 9 to make it disengage from the triangular block 7, and then the pull rope 17 is pulled to drive the hook 11 to open outward synchronously, and the torsion spring 13 is tightened, and then the connector 4 is pulled out and the pull rope 17 is released;

[0030] When other joints 4 need to be installed, the butt joint 6 on the joint 4 can be directly inserted into the end face of the second movable tube 3, and the hook 11 can be pushed outward by using the inclined surface of the triangular block 7, and the triangular block 7 can be clamped by the force of the torsion spring 13, and then the locking cylinder 8 is rotated to drive the hook 11 to tighten the joint 4 for secondary fixation, which effectively improves its stability and sealing.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
