Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a fire-fighting device for emergency use on ships. Background Technology

[0002] Ships may catch fire unexpectedly while sailing at sea. In such cases, emergency firefighting equipment is needed for rapid extinguishing. Marine firefighting equipment refers to various firefighting devices designed and manufactured to prevent and extinguish fires at sea. During firefighting at sea, high-pressure pumps can be used to directly introduce seawater into fire hydrants for extinguishing. This method is called "seawater firefighting." Its principle is to pump seawater from distant waters (such as bays or ports) to the area where the fire is occurring, and then use the fire hydrant system to extinguish the fire. In this way, the water supply in the fire hydrants can be continuously replenished, ensuring sufficient firefighting power.

[0003] In existing ship fire-fighting systems, seawater is first pumped into the system through pipelines using a high-pressure pump located at the bottom of the ship. Because these pipelines are typically long, the gas inside cannot be expelled in time. This causes the seawater to compress the gas during pumping, resulting in high pressure within both the system and the pipelines. Prolonged high pressure can damage internal components and pipes. Furthermore, it prevents seawater from quickly and efficiently entering the system, significantly reducing the speed of water jetting and thus decreasing the fire-fighting rate. For example, Chinese utility model patent CN217311692U discloses a wet-type ship fire-fighting system. This system, because its piping is normally filled with air, requires venting the air before water can be released after opening the fire hydrant, resulting in a delay in water flow and impacting the timeliness of firefighting and disaster relief. Summary of the Invention

[0004] In view of the problem that the gas in the fire-fighting pipeline of the existing ship emergency fire-fighting device cannot be discharged in a timely and rapid manner, thus affecting the fire-fighting speed, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a fire-fighting device for ship navigation emergency, which aims to: enable the gas in the pipeline and fire-fighting device to be discharged quickly, accelerate the spraying speed of seawater, and achieve rapid fire extinguishing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a fire-fighting device for marine emergency response, including a mounting base, a water outlet pipe disposed on the top of the mounting base, a water outlet disposed on the top of the water outlet pipe, and a valve between the water outlet pipe and the water outlet. It also includes an exhaust unit disposed on the water outlet pipe. The exhaust unit includes an exhaust assembly disposed on the wall of the water outlet pipe. The exhaust assembly includes an exhaust hole opened on the wall of the water outlet pipe, an exhaust plate disposed in the exhaust hole, rotating rods symmetrically disposed on both sides of the exhaust plate, and a torsion spring disposed between the rotating rods and the exhaust plate. The rotating rods are rotatably connected to the wall of the water outlet pipe. The exhaust plate is used to open or close the exhaust hole.

[0007] In a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the length of the exhaust plate is greater than the length of the exhaust hole, the width of the exhaust plate is less than the width of the exhaust hole, and the exhaust plate is inclined inside the exhaust hole to facilitate the rotation of the exhaust plate and ensure the opening or closing effect of the exhaust hole.

[0008] As a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the number of exhaust components is multiple, and they are arranged in a ring array on the wall of the water outlet pipe.

[0009] As a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the exhaust unit further includes a squeezing assembly disposed on the water outlet pipe. The squeezing assembly includes a fixing ring fixed on the water outlet pipe and a squeezing pipe slidably disposed on the water outlet pipe. A squeezing groove is formed on the pipe wall of the squeezing pipe. An elastic element and a rotating assembly are disposed in the squeezing groove. One end of the elastic element is connected to the fixing ring, and the other end of the elastic element is connected to the squeezing pipe through the rotating assembly.

[0010] In a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the elastic element is any device that can provide elastic force, such as a spring or rubber.

[0011] In a preferred embodiment of the marine emergency fire-fighting device described in this utility model, the exhaust unit further includes a locking assembly. The locking assembly comprises an L-shaped groove formed on the wall of the outlet pipe and a locking rod disposed within the L-shaped groove, with one side of the locking rod fixedly connected to the bottom wall of the extrusion pipe. The function of the locking assembly is to lock the extrusion pipe of the extrusion assembly after it is pulled down to the exhaust plate position, thereby compressing the exhaust plate and improving the compaction effect.

[0012] In a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the rotating assembly includes a rotating groove formed at the bottom of the extrusion groove, and a rotating block disposed within the rotating groove, with the top of the rotating block fixedly connected to an elastic element. The form of the rotating groove and the rotating block is not specifically limited; for example, the rotating groove can be a T-groove or a dovetail groove, etc., as long as the rotating block can match the rotating groove and slide within it. The function of the rotating assembly is to rotate the extrusion tube to drive the locking rod, causing the locking rod to be in different positions within the L-shaped groove. This allows the extrusion tube to remain at the position of the extrusion exhaust plate or slide above the exhaust plate under the action of the elastic element, achieving a locked or unlocked state.

[0013] As a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the inner wall of the extrusion tube is provided with an extrusion slope, and the position of the extrusion slope corresponds to that of the exhaust plate.

[0014] As a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the exhaust unit further includes a sealing component, which includes a first sealing strip disposed on the top of the exhaust plate facing the outside of the outlet pipe, a first sealing groove opened on the inner wall of the outlet pipe and matching the first sealing strip, a second sealing strip disposed on the bottom of the exhaust plate facing the inside of the outlet pipe, a second sealing groove opened on the outer wall of the outlet pipe and matching the second sealing strip, a third sealing groove symmetrically opened on both sides of the exhaust hole, and a third sealing strip disposed in the third sealing groove.

[0015] As a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, one side of the rotating rod is rotatably connected to the side wall of the third sealing groove, and the third sealing strip abuts against the side of the exhaust plate.

[0016] In a preferred embodiment of the shipboard emergency fire-fighting device described in this utility model, the third sealing groove is inclined to match the inclined exhaust plate and improve the sealing effect.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up an exhaust unit, in the event of a fire during navigation, the seawater can be pumped in to quickly expel the gas in the fire-fighting device and connecting pipes. After the exhaust is completed, the exhaust plate blocks the exhaust hole under the impact pressure of the seawater, which also prevents most of the seawater from overflowing from the exhaust unit, allowing the seawater to be pumped out quickly and achieving the effect of rapid fire extinguishing.

[0019] 2. After the seawater is pumped out, the squeezing assembly, locking assembly, and sealing assembly work together to pull down the squeezing tube of the squeezing assembly, causing the locking rod to slide downwards in the L-shaped groove. Rotating the squeezing tube causes the locking rod to be locked in the transverse groove at the bottom of the L-shaped groove, thus achieving squeezing and sealing of the exhaust assembly by the squeezing tube. This ensures that the first and second sealing strips are firmly squeezed into the first and second sealing grooves, and the exhaust plate firmly blocks the exhaust hole, improving the sealing performance of the water outlet pipe when water is discharged, increasing the water pressure in the water outlet pipe, ensuring the water spray pressure of the fire hose, and improving the fire extinguishing efficiency.

[0020] 3. After the fire is extinguished, the locking components can remain locked to prevent dust and impurities from entering the fire-fighting device, thus improving the cleanliness and service life of the device. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Example 1, referring to Figures 1-3 This embodiment provides a marine emergency fire-fighting device, including a mounting base 1, a water outlet pipe 11 mounted on the top of the mounting base 1, valves 12 symmetrically mounted on both sides of the top of the water outlet pipe 11, and a water outlet 13 mounted on the bottom of the valves 12, and an exhaust unit mounted on the water outlet pipe 11; the exhaust unit includes an exhaust assembly 5 disposed on the wall of the water outlet pipe 11, the exhaust assembly 5 includes an exhaust hole 51 opened on the wall of the water outlet pipe 11, an exhaust plate 52 disposed in the exhaust hole 51, rotating rods 53 symmetrically disposed on both sides of the exhaust plate 52, and a torsion spring disposed between the rotating rods 53 and the exhaust plate 52, wherein the rotating rods 53 are rotatably connected to the wall of the water outlet pipe 11, and the exhaust plate 52 is used to open or close the exhaust hole 51.

[0031] To improve the sealing effect, the length of the exhaust plate 52 is greater than the length of the exhaust hole 51, and the width of the exhaust plate 52 is slightly smaller than the width of the exhaust hole 51. The exhaust plate 52 is inclined inside the exhaust hole 51 to facilitate the rotation of the exhaust plate and ensure the opening or closing effect of the exhaust hole.

[0032] The torsion spring tilts the exhaust plate 52 relative to the exhaust hole 51, which can keep the exhaust hole 51 open. However, when the pumped seawater impacts the exhaust plate 52, the torque provided by the torsion spring is much less than the seawater pressure, causing the exhaust plate 52 to rotate against the torque of the torsion spring and block the exhaust hole 51.

[0033] There are four exhaust assemblies 5 arranged in a circular array at 90° intervals on the wall of the water outlet pipe 11. The multiple exhaust assemblies evenly arranged on the water outlet pipe facilitate the improvement of exhaust speed.

[0034] The exhaust unit also includes a squeezing assembly 2 disposed on the water outlet pipe 11. The squeezing assembly 2 includes a fixing ring 21 fixed on the water outlet pipe 11 and a squeezing tube 23 slidably disposed on the water outlet pipe 11. A squeezing groove 25 is provided on the wall of the squeezing tube 23. Specifically, the squeezing tube 23 is a double-walled tube, and a squeezing groove 25 with an open upper end and a closed lower end is formed between the two layers of walls.

[0035] The elastic element 22 and the rotating assembly 3 are disposed within the extrusion groove 25. The rotating assembly 3 includes a rotating groove 31 formed at the bottom of the extrusion groove 25 and a rotating block 32 disposed within the rotating groove 31, with the top of the rotating block 32 fixedly connected to the elastic element 22. As an example, the rotating groove 31 can be integrally formed with the extrusion tube 23, or it can be a separate component fixed to the bottom of the extrusion groove 25. As an example, the groove shape of the rotating groove is a T-shaped groove, therefore its matching rotating block 32 also has a T-shaped protrusion. Of course, the rotating groove 31 can also be other shapes such as a dovetail groove. A rotating groove 31 and a rotating block 32 that can fit together and rotate relative to each other can be options for this embodiment. As an example, the elastic element 22 is a spring.

[0036] The exhaust unit also includes a locking component 6, which includes an L-shaped groove 61 opened on the wall of the water outlet pipe 11 and a locking rod 62 disposed in the L-shaped groove 61, and one side of the locking rod 62 is fixedly connected to the bottom wall of the extrusion pipe 23.

[0037] The inner wall of the extrusion tube 23 is provided with four extrusion slopes 24 arranged in a ring at 90° intervals. The extrusion slopes 24 correspond to the positions of the exhaust plate 52. When the extrusion tube 23 is pulled down to the locked position, the extrusion slopes 24 can be used to press the bottom of the exhaust plate 52 and block the exhaust hole 51.

[0038] In the prior art, when a fire occurs, the seawater pump pressure system is turned on first, but the gas in the pipes and fire-fighting equipment cannot be discharged quickly, which will prevent the seawater from entering the fire-fighting equipment quickly. In this embodiment, by setting an exhaust unit, the gas in the fire-fighting equipment and connecting pipes can be discharged quickly after the seawater is pumped in, so that the seawater can be pumped out quickly and achieve the effect of rapid fire extinguishing.

[0039] Specifically, when the fire is not extinguishing, by pulling down the squeezing tube 23 of the squeezing assembly 2 and rotating the squeezing tube 23, the locking rod 62 is locked into the transverse groove at the bottom of the L-shaped groove. This causes the squeezing inclined surface 24 to press down the vent plate 52 on the water outlet pipe 11, blocking the vent hole 51 and preventing dust and impurities from entering the water outlet pipe 11, thus keeping the interior clean and avoiding affecting the water output during fire extinguishing. At this time, since the squeezing tube 23 is connected to the rotating block 32 through the rotating groove 31, pulling down the squeezing tube 23 causes the rotating block 32 to move downward, and the elastic element 22 is stretched by the downward movement of the rotating block 32.

[0040] During fire extinguishing, first rotate the squeezing tube 23 of the squeezing assembly 2, causing the locking rod 62 to move out of the horizontal groove at the bottom of the L-shaped groove and into the vertical groove. This prevents the squeezing tube 23 from being locked by the locking assembly 6. The squeezing tube 23 is then reset by the resetting action of the elastic element 22, causing the squeezing tube 23 to move upward. This causes the exhaust plate 52 of the exhaust assembly 5 to rotate under the action of the torsion spring, tilting relative to the exhaust hole 51. The exhaust hole 51 is then opened, allowing for rapid water discharge. After the exhaust process is complete, seawater enters the water outlet pipe 11. Due to the high pressure of the seawater when it is pumped up, the four exhaust plates 52, under the impact of the seawater, overcome the torsion force of the torsion spring and rotate counterclockwise to block the exhaust hole 51, thus sealing the water outlet pipe 11 during water discharge.

[0041] Example 2 is an improvement on Example 1, which adds a sealing component 4 to improve the sealing performance of the exhaust unit when water is discharged.

[0042] Please refer to Figures 4-5 The sealing assembly 4 includes a first sealing strip 41 disposed on the top of the vent plate 52 facing the outside of the outlet pipe 11, a first sealing groove 42 formed on the inner wall of the outlet pipe 11 and matching the first sealing strip 41, a second sealing strip 43 disposed on the bottom of the vent plate 52 facing the inside of the outlet pipe 11, a second sealing groove 44 formed on the outer wall of the outlet pipe 11 and matching the second sealing strip 43, and a third sealing groove 45 symmetrically formed on both sides of the vent hole 51, with a third sealing strip disposed in the third sealing groove 45. The first, second, and third sealing strips are made of rubber or other materials with sealing properties. One side of the rotating rod 53 is rotatably connected to the side wall of the third sealing groove 45, and the third sealing strip can seal and wrap the rotating rod 53 and abut against the side of the vent plate 52. The third sealing groove 45 is inclined to match the inclined vent plate, improving the sealing effect.

[0043] Specifically, after the venting process is completed, the venting plate 52 rotates counterclockwise under the impact of seawater, overcoming the torsion of the torsion spring. This causes the first sealing strip 41 and the second sealing strip 43 to be respectively inserted into the first sealing groove 42 and the second sealing groove 44. The first sealing strip 41 and the second sealing strip 43 are made of rubber and are pressurized to fit the first sealing groove 42 and the second sealing groove 44. After the venting plate 52 rotates, its two sides abut against the third sealing strip of the third sealing groove 45, which improves the sealing performance of the water outlet pipe 11 when water is discharged. Furthermore, the extrusion tube 23 can be pulled down so that the extrusion slope 24 can press the bottom of the venting plate 52, so that the first sealing strip 41 and the second sealing strip 43 can be firmly pressed into the first sealing groove 42 and the second sealing groove 44. At the same time, since the third sealing strip is also provided in the third sealing groove 45 on both sides of the venting hole 51, the sealing performance of the water outlet pipe 11 when water is discharged is further improved, the water pressure in the water outlet pipe 11 is increased, the water spray pressure of the fire hose is guaranteed, and the fire extinguishing efficiency is improved.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
