The power device provides strong power to drive the pump body to operate. The impeller rotates at high speed to make the water obtain centrifugal force, and a large amount of water flow is sucked into the pump body inlet. Through the precisely designed flow channel, the water flow is accelerated and pressurized to form a high pressure state. The sealing device prevents liquid leakage and ensures stable operation. Finally, the high pressure and large flow water is precisely sprayed out through the pipeline component, and the range is much longer than that of ordinary fire pumps, efficiently covering the long distance fire scene.

[0033] As Figure 1 , Figure 3 and Figure 4 , the embodiment provides a high-pressure large-flow long-range fire pump,

[0034] A high-pressure large-flow long-range fire pump undertakes a key responsibility in fire extinguishing operation, comprising a pump body 1, the top end of the pump body 1 is fixedly connected with a mounting port 2, as a key part of subsequent pipeline access, the design precision degree of the mounting port 2 is directly related to the stability and sealing property of the fire pump operation, the docking mechanism for pipeline quick docking is carefully arranged in the mounting port 2, so that the water source can be quickly accessed to the pump body 1 in fire extinguishing action, and the opportunity of rescue is avoided to be delayed;The bottom end of the pump body 1 is fixedly connected with a fixed plate 13, the fixed plate 13 plays a role of stable support, and the drive mechanism arranged at the bottom end of the fixed plate 13 creates more for flexible operation of the fire pump;

[0035] Inside the installation port 2, there is a fixed ring 3 connected in a sliding manner. The fixed ring 3 is crucial for achieving a stable connection between the liquid inlet pipe and the pump body 1. The size of the fixed ring 3 is adapted to the installation port 2 to ensure smooth connection. Inside the fixed ring 3, there is a sliding ring 4 connected in a sliding manner. The sliding ring 4 is very flexible during the entire docking process and can flexibly change its position inside the fixed ring 3 according to different operation stages. On the outside of the sliding ring 4, there is a fixed connection of a limiting block 5. The limiting block 5 guides the direction for the sliding ring 4 and the entire pipeline docking process. Inside the installation port 2, there is a limiting groove 6 opened. The limiting block 5 slides inside the limiting groove 6. The "L" - shaped design of the limiting groove 6 plans the movement trajectories of each component during pipeline docking to ensure accurate operation. At the top of the sliding ring 4, there is a fixed connection of a rotating ring 7. The rotating ring 7 can trigger a series of interlocking actions to promote the pipeline docking to achieve the final sealed and fitted state. Inside the fixed ring 3, there is a fixed connection of a telescopic spring 8. The telescopic spring 8 stores elastic potential energy and will push relevant components to complete key actions at the right time;

[0036] Inside the telescopic spring 8, there is a telescopic column 9 sleeved. The telescopic column 9 provides a stable support structure for the telescopic spring 8 to prevent the spring from shifting and also assists in fixing the relative positional relationship between the sliding ring 4 and the fixed ring 3. The other end of the telescopic spring 8 is fixedly connected to the bottom end of the sliding ring 4. The limiting groove 6 is in an "L" shape.

[0037] Embodiment Two

[0038] As Figures 1 to 2 shown, where the same or corresponding components as in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The differences between this Embodiment Two and Embodiment One are as follows:

[0039] The driving mechanism comprises a transmission rod 14 for conducting force, the top end of which is rotationally connected to the top end of the fixed plate 13 to accurately transmit power and open the angle adjustment action. The end of the transmission rod 14 away from the fixed plate 13 is rotationally connected with a sliding block 15, the rear end of which is fixedly connected with a gas cylinder 16. The sliding block 15 acts as a key power receiving point in subsequent angle adjustment, receives the thrust from the gas cylinder 16, and converts it into appropriate action. The gas cylinder 16 is a direct power provider for angle adjustment, and the linear thrust generated initiates a series of angle changes. The outside of the gas cylinder 16 is fixedly connected with a base 20, which provides stable support for the entire driving mechanism and ensures the stability of the coordinated operation of the components. The top end of the base 20 is provided with a sliding groove 17, which defines a precise route for the sliding of the sliding block 15 to ensure accurate and error-free pushing action each time, making the angle adjustment more accurate. The outside of the sliding block 15 is slidingly connected inside the sliding groove 17. The bottom end of the fixed plate 13 is rotationally connected to the top end of the base 20. The top end of the base 20 is fixedly connected with a support block 18, which enhances the stability of the base 20 and makes the entire angle adjustment process safer and more reliable.

[0040] Working steps

[0041] When it is necessary to use the fire pump jet to extinguish fire, the fixed ring 3 at the bottom end of the liquid inlet 10 is slid into the inside of the mounting port 2. While the fixed ring 3 slides inside the mounting port 2, the outside of the limiting block 5 will slide inside the limiting groove 6. When the bottom end of the fixed ring 3 contacts the outside of the sealing ring 11, the sliding ring 4 and the fixed ring 3 are rotated inside the mounting port 2 by rotating the rotating ring 7, and the limiting block 5 is transversely slid inside the limiting groove 6 at the same time. At this time, by canceling the control of the rotating ring 7, the telescopic spring 8 will push the sliding ring 4 to slide inside the fixed ring 3, so that the limiting block 5 is clamped in the groove inside the limiting groove 6. The bottom end of the fixed ring 3 is in close contact with the top end of the sealing ring 11, and finally the quick sealing butt joint between the liquid inlet 10 and the mounting port 2 is realized. At this time, by controlling the rotating speed of the motor 12, the liquid is sprayed to achieve the effect of extinguishing fire.

[0042] The angle of the fire pump can be adjusted to face different spraying scenarios. By starting the gas cylinder 16, the gas cylinder 16 will push the sliding block 15 to slide inside the sliding groove 17, so that the transmission rod 14 pushes the fixed plate 13 to rotate at the top end of the base 20, thereby realizing the change of angle. Through the adjustment of the angle, the flexibility of fire extinguishing is improved, the safety of the firefighters is ensured, different building styles are adapted, and the efficiency of fire extinguishing is improved.

[0043] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
