Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a mobile fire-fighting monitor. Background Art
[0002] Fire monitors are essential firefighting equipment for extinguishing fires from a distance. Based on their mounting method, they can be categorized as fixed or mobile. Mobile monitors are those mounted on a removable support or trailer. Mobile monitor technology is currently experiencing rapid development, primarily due to their superior jet performance. They offer longer range and greater flow rates than hoses, enabling remote fire extinguishing and temperature reduction.
[0003] Mobile fire monitors have several advantages when extinguishing fires:
[0004] 1. Mobility: Mobile fire monitors can be carried and moved to the fire scene at any time, especially to corners that are inaccessible to vehicles, and put into use quickly.
[0005] 2. Long-range extinguishing capability: Unlike fire hoses, mobile fire monitors usually have a larger flow rate and a longer range, allowing them to extinguish fires at a greater distance.
[0006] It should be noted that when a fire monitor is spraying a jet, the greater the flow rate and pressure, the greater the recoil. Fixed fire monitors are installed through flanges or threads, and the recoil does not pose too much risk. However, mobile fire monitors are generally grounded through chassis, brackets, etc. Once the recoil is out of control, the overturning of the monitor body can easily cause loss of life and property in the surrounding environment.
[0007] A mobile fire monitor consists of a water inlet base, a monitor body, and a monitor head. The water inlet base includes a water inlet interface and a water outlet interface. There can be one or more water inlets, while there is generally only one water outlet interface. The water inlet base is generally foldable to save transportation space and is required to be as light as possible, while also taking stability into consideration. Light weight affects handling performance, while stability affects the safe use of the mobile fire monitor. It is also ideal if the water inlet base can be quickly separated from the monitor body, allowing it to be disassembled into two parts, effectively distributing the weight and facilitating separate transportation by multiple firefighters for quick installation and deployment.
[0008] The first type of existing mobile fire monitor bases mostly utilizes four to six steel nails anchored to the ground via a bracket. To reduce weight and facilitate transport, the brackets are typically short and foldable. Most currently available models cannot quickly separate the base from the monitor body for separate transport. A small number of models offer separation between the base and the monitor head, but the base and bracket have never been separated. Furthermore, base stability needs to be improved. For example, a longer bracket would provide better stability. However, a longer bracket also increases its weight, making it difficult to separate and transport. Therefore, a mobile fire monitor that can be disassembled for easy transport while ensuring safety and stability is needed. Utility Model Content

DETAILED DESCRIPTION
[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.
[0035] In some comparative embodiments, the base of the mobile fire monitor is put on the ground in the form of a trolley with wheels. This only takes into account the convenience of transportation, but does not take into account the recoil when the water monitor is spraying. Even if the casters have brakes or locking structures, the strong recoil will cause the base or chassis to move continuously backward, and someone must hold it up before it can be used normally. This is actually very dangerous.
[0036] Therefore, in order to ensure safety and facilitate transportation, refer to Figures 1 to 4 As shown, the embodiment of the present utility model provides a mobile fire monitor, comprising:
[0037] The gun body 100 is provided with a first water inlet 110. The gun body 100 is manually controlled, and a user can control the pan and tilt of the gun body 100 using a handle. The pan can be 360 degrees, and the pitch can be approximately -45 degrees to +75 degrees. A valve is also provided at the first water inlet 110 to control the opening and closing of the first water inlet 110.
[0038] The water inlet base 200 includes a pipe 210 and a base 220 located at the bottom of the pipe 210. A second water inlet 211 and a water outlet 212 are located at either end of the pipe 210. The second water inlet 211 is connected to a fire hose. The water outlet 212 is detachably connected to the first water inlet 110. The water inlet base 200 redirects the horizontal incoming water upward and into the gun body 100.
[0039] The bracket 300 includes a bracket base 310, a first bracket leg 320, a second bracket leg 330, and a locking member 340. The bracket base 310 is cast. The bracket base 310 includes a main body 311 and ears 312 connected to both sides of the top of the main body 311. The base 220 is located on the bracket base 310 and is detachably connected to the ears 312. The first bracket leg 320 is connected to the bottom of the bracket base 310 via two M8 screws and the first bracket leg 320 cannot rotate. The first bracket leg 320 and the second bracket leg 330 are both retractable. The second bracket leg 330 is rotatably connected to the bottom of the first bracket leg 320 via the locking member 340, and the locking member 340 is configured to lock the second bracket leg 330 and the first bracket leg 320. The bottoms of both ends of the first bracket leg 320 and the second bracket leg 330 are provided with spikes 350 for gripping the ground. When in working state, the bottom of the spike 350 of the first bracket leg 320 is flush with the bottom of the spike 350 of the second bracket leg 330 .
[0040] In this way, when in operation, the locking member 340 is released, and the second support leg 330 is rotated and extended from the bottom of the first support leg 320 until the two are perpendicular, and then locked with the locking member 340. The length of the first and second support legs 320, 330 can be adjusted according to different pressures and recoil forces. When in transport mode, the ear portion 312 is removed from the base 220, and the water outlet 212 is removed from the first water inlet 110, so that the gun body 100, the water inlet base 200, and the support 300 are separated. After the first and second support legs 320, 330 are retracted, the locking member 340 is released and the second support leg 330 is rotated until it retracts below the first support leg 320.
[0041] Specifically, this embodiment enables rapid disassembly and installation of the monitor body 100 and the water inlet base 200, and of the water inlet base 200 and the bracket 300. This allows for the mobile monitor to be distributed in weight, making it easier for multiple firefighters to carry the monitor separately on-site and facilitating quicker transport to the deployment point. Furthermore, in this embodiment, the second bracket leg 330 can be folded underneath the first bracket leg 320, eliminating space and facilitating transport. The first and second bracket legs 320, 330, are retractable, providing a longer and more stable mobile monitor base bracket.
[0042] The three modules—the cannon body 100, the water inlet base 200, and the bracket 300—can be quickly disassembled and folded, making it easier to transport and move the monitor on-site, allowing for quick deployment to a designated location. To accommodate varying pressures and recoil forces, the monitor can be configured with retractable, longer, and more stable legs, effectively improving safety during use.
[0043] Furthermore, the base 220 is provided with a sleeve 221 at its bottom. An indexing plunger 313 is threadedly connected to the ear 312. The sleeve 221 is positioned between the two ears 312, and two indexing plungers 313 extend into the ends of the sleeve 221, respectively, to clamp the base 220. The indexing plunger 313 is an L-shaped handle-type indexing plunger 313. When the handle is rotated 90° upward, the indexing plunger 313 retracts, allowing the water inlet base 200 and the bracket 300 to be separated. Specifically, this embodiment is convenient and quick to operate, allowing for quick separation of the water inlet base 200 and the bracket 300.
[0044] Furthermore, a plurality of positioning pins 314 are provided on the top of the bracket seat 310; a plurality of positioning pin holes 222 are provided on the seat body 220, and the positioning pin holes 222 are arranged in a one-to-one correspondence with the positioning pins 314, and the positioning pins 314 are inserted into the positioning pin holes 222. In some embodiments, the positioning pins 314 are ball-head positioning pins. The tail end of the positioning pin 314 is provided with a threaded hole, and the threaded hole is connected to the screw passing through the bracket seat 310, thereby realizing the connection between the positioning pin 314 and the bracket seat 310. Specifically, the positioning pins 314 provided in this embodiment can provide a quick positioning function when the water inlet base 200 and the bracket 300 are installed, and then facilitate the quick alignment of the indexing plunger 313 and the sleeve 221, thereby realizing the quick installation of the water inlet base 200 and the bracket 300.
[0045] Furthermore, the locking member 340 is a knob screw with a handle. The bracket base 310 is provided with a threaded hole, and the first and second bracket legs 320 and 330 are provided with connecting holes coaxial with the threaded holes. The knob screw passes through the connecting holes of the first and second bracket legs 320 and 330 and connects with the threaded holes. Specifically, by rotating the knob screw in this embodiment, the bracket can be switched to the working state (i.e., unfolding the second bracket leg 330) as follows: loosening the knob screw from the threaded hole, rotating the second bracket leg 330 until it is perpendicular to the first bracket leg 320, and then tightening the knob screw to secure the first and second bracket legs 320 and 330 to the bracket base 310. By rotating the knob screw in this embodiment, the bracket can be switched to the carrying state (i.e., folding and retracting the second bracket leg 330) as follows: loosening the knob screw from the threaded hole, rotating the second bracket leg 330 until it is directly below the first bracket leg 320, and then tightening the knob screw to secure the first and second bracket legs 320 and 330 to the bracket base 310. It can be seen that this embodiment can conveniently and quickly realize the deployment and folding of the first bracket leg 320 and the second bracket leg 330 , has a simple structure, and is convenient and quick to operate.
[0046] Furthermore, two connecting plates 360 are provided at the bottom of the bracket seat 310, perpendicular to the first bracket leg 320. Positioning slots 361 are provided at the bottom of the connecting plates 360. Specifically, in this embodiment, after the second bracket leg 330 is rotated to be perpendicular to the first bracket leg 320, the second bracket leg 330 can be locked in the positioning slots 361, and the knob screw can then be tightened. Thus, the positioning slots 361 provided in this embodiment further limit the position of the second bracket leg 330 in the operating state, preventing rotational displacement.
[0047] Furthermore, the telescopic structure of the first support leg 320 is as follows: the first support leg 320 includes an outer sleeve 321 and an inner sleeve 322 connecting the two ends of the outer sleeve 321. The outer sleeve 321 is provided with a first connection hole; the inner sleeve 322 is provided with a second connection hole at each end. The inner sleeve 322 is inserted into the outer sleeve 321, and the first and second connection holes are fixedly connected by a tightening screw 323. A spike 350 is provided at one end of the inner sleeve 322. Specifically, in this embodiment, the first connection hole connects to the second connection hole at different positions to achieve the telescopic movement of the first support leg 320. In some embodiments, the outer sleeve 321 and the inner sleeve 322 are stainless steel square tubes.
[0048] Furthermore, the telescopic structure of the first support leg 320 is the same as the telescopic structure of the second support leg 330 .
[0049] Furthermore, the first water inlet 110 is provided with a first KY-type threaded connection, while the second water inlet 211 is provided with a second KY-type threaded connection that mates with the first KY-type threaded connection. Specifically, this embodiment utilizes the coordination of the first and second KY-type threaded connections to enable rapid installation and removal of the water inlet base 200 and the cannon body 100. In other embodiments, the water inlet base 200 and the cannon body 100 may also be connected using other detachable methods, such as a snap-fit connection.
[0050] Furthermore, the second water inlet 211 is connected to a flexible joint 230. Specifically, the flexible joint 230 provided in this embodiment is a knot-proof structure, which can prevent the fire hose from being knotted during use after the water inlet is connected to the fire hose.
[0051] Furthermore, a ball valve 240 for controlling the water inlet switch is provided in the water inlet base 200 near the water inlet. The ball valve 240 has a handle, and the water inlet switch is adjusted by the handle.
[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
