Description

Technical Field

[0001] This utility model relates to the field of fire monitors, and in particular to a fire monitor anti-impact protective cover and an anti-impact fire monitor thereof. Background Technology

[0002] Fire monitors are modern, intelligent fire extinguishing devices that use water as the spray medium. They can be operated manually or automatically to spray water jets to extinguish fires. The working principle of a fire monitor is as follows: when a fire occurs, the detector at the front end of the monitor automatically collects infrared images of the fire scene. The central controller automatically detects and locates the fire position. After the monitor head is adjusted, the solenoid valve is activated to open the pipeline and spray directly at the fire location until the fire is extinguished. Fire monitors with a double U-shaped symmetrical structure have good torsional resistance and high spray accuracy, leading to their increasingly widespread application. However, a problem exists in their use: the instant the solenoid valve opens the pipeline and activates the monitor, the two high-pressure water streams from the two U-shaped tubes simultaneously converge into the tee pipe. This instantaneous surge of force within the tee pipe can cause the flange between the U-shaped tubes and the tee pipe to burst due to the inability to withstand the impact, rendering the monitor unusable. Furthermore, the detached U-shaped tubes and monitor head falling from a height pose a significant safety hazard. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an impact-resistant protective cover for a water cannon and an impact-resistant fire water cannon thereof.

[0004] The technical solution of this utility model is: a water cannon impact-resistant protective cover, including a main body and two end plates vertically connected to both ends of the main body. The end plates are welded and fixed to the end face of the main body, and the end plates are provided with a number of connection holes.

[0005] Preferably, the main body is an arc-shaped plate, with two end plates symmetrically arranged at the two ends of the arc-shaped plate.

[0006] Preferably, the end plate is fan-shaped, with several connection holes evenly distributed along its inner edge.

[0007] Preferably, the main body has a U-shaped notch in the middle, and there are transition rounded corners on both sides of the port of the U-shaped notch.

[0008] Preferably, a plurality of reinforcing ribs are evenly provided between the inner surfaces of the end plate and the main body. The reinforcing ribs are right-angled triangles, with their short right-angled sides welded to the end plate and their long right-angled sides welded to the main body for fixation.

[0009] An impact-resistant fire monitor includes two U-shaped pipes symmetrically connected to an inlet support, and a tee pipe seat rotatably connected between the two U-shaped pipes. The bottom of the inlet support is provided with a flange that connects to a water pipe. The monitor head is installed at the middle pipe port of the tee pipe seat. It also includes the aforementioned impact-resistant protective cover for the monitor. The ends of the U-shaped pipes are connected to rotary joints through flanges. The tee pipe seat is connected between the two rotary joints. A worm gear is fixedly fitted at one end of the tee pipe seat. A geared motor is installed on the upper part of the inlet support. A worm gear that meshes with the worm gear is connected to the output shaft of the geared motor. The protective cover is fitted between the outer sides of the flanges of the two U-shaped pipes. Screws on the flanges are inserted into the connection holes to fix the end plates.

[0010] Preferably, the U-shaped notch corresponds to the position of the middle tube body of the tee fitting, and the size of the U-shaped notch is larger than the size of the middle tube body.

[0011] Preferably, a gap is provided between the main board body and the three-way pipe socket.

[0012] The beneficial technical effects of this utility model are as follows: a protective cover is installed between the flanges of the two U-shaped pipes of the fire monitor. The protective cover forms an auxiliary reinforcement structure between the two U-shaped pipes. When the fire monitor is started, the original rotating connection structure of the fire monitor, combined with the newly added auxiliary reinforcement structure, can fully resist the huge impact force generated by the two water flows, ensure the safety and stability of the fire monitor's own structure, and avoid the safety hazards caused by parts falling off.

[0020] Example 1, see appendix Figure 5 An impact-resistant protective cover for a water cannon includes a main body 11 and two end plates 12 vertically connected to both ends of the main body. The end plates are provided with a number of connection holes 13, which can correspond to the mating holes on the flange 24 of the U-shaped tube 22 on the water cannon. The two can be mated by installing screws 25. The main body 11 is an arc-shaped plate, and the two end plates 12 are symmetrically arranged at the two ends of the arc-shaped plate. The end plates are fan-shaped in general. The number of connection holes 13 are evenly distributed on the inner edge of the end plates 12. The arc-shaped plate itself has high resistance to deformation. After the end plates 12 are welded and fixed at both ends, the strength is further improved, forming a stable protective cover structure.

[0021] The main board body 11 has a U-shaped notch 14 in the middle, through which the main board body 11 avoids the T-shaped pipe seat 23 of the water cannon.

[0022] A number of reinforcing ribs 15 are evenly provided between the inner surfaces of the end plate 12 and the main body 11. These reinforcing ribs increase the fixed connection strength between the end plate and the main body, thereby improving their reinforcement and protection effect.

[0023] Example 2, see appendix Figure 1-6 An impact-resistant fire monitor includes two U-shaped pipes 22 symmetrically connected to an inlet support 21, a three-way pipe seat 23 rotatably connected between the two U-shaped pipes, a monitor head 27 installed at the middle pipe port of the three-way pipe seat 23, and an impact-resistant protective cover 1 as described in Embodiment 1. The ends of the U-shaped pipes 22 are connected to a rotary joint 26 via flanges 24. The three-way pipe seat 23 is connected between the two rotary joints 26. The three-way pipe seat 23 rotates linearly between the two U-shaped pipes via the rotary joints to adjust the angle of the monitor head for aiming at the fire point. The protective cover 1 is fitted between the outer sides of the flanges 24 of the two U-shaped pipes 22. Screws 25 on the flanges 24 are inserted into the connecting holes 13 to fix the end plates 12. The protective cover 1 forms a fixed reinforcement structure on the outside of the two U-shaped pipes 22.

[0024] The U-shaped notch 14 corresponds to the position of the middle tube of the three-way tube seat 23. The three-way tube seat 23 can rotate downward to enter the U-shaped notch 14, ensuring that the gun head 27 has a sufficient rotation angle. There is a gap between the main body 11 and the three-way tube seat 23 to avoid interference between the three-way tube seat 23 and the protective cover 1 during rotation.

[0025] When the fire monitor in this embodiment is in use, the fire water enters the T-shaped pipe 23 simultaneously from the U-shaped pipes 22 on both sides. After converging in the T-shaped pipe 23, it sprays out from the nozzle 27. At the moment of starting the fire monitor, the original rotating connection structure of the fire monitor combined with the newly added protective cover 1 forms an auxiliary reinforcement structure, which can fully resist the huge impact force generated by the two water streams in the T-shaped pipe 23. This avoids the phenomenon that the flange 24 between the U-shaped pipe 22 and the T-shaped pipe 23 cannot withstand the impact force and bursts open, thus ensuring the safety and stability of the fire monitor's own structure.
