Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fire extinguishing device, in particular to a modular multi-tube fire extinguishing device and a use method thereof. BACKGROUND

[0002] Forest fire is a natural disaster with wide occurrence, strong burst, great destruction and difficult to put out in the world. Controlling forest fire is a worldwide problem, and countries around the world attach great importance to it and explore and develop various forest fire extinguishing equipment and use different means to extinguish fire. However, due to the complex geographical environment, variable climate and poor traffic in forest areas, it is difficult to effectively control the fire by traditional manual fighting, water spraying or fan equipment, and once the favorable opportunity is lost, the fire scene will be in a passive situation, causing large-scale forest fires. At the same time, due to the traditional fire extinguishing method, the fire extinguishing personnel are close to the fire scene, which is very dangerous, and often causes accidents due to the change of wind direction in the fire scene and the failure of the fire extinguishing personnel to evacuate in time.

[0003] In summary, it is difficult to put out forest fires, and conventional fire extinguishing means are restricted by weather and terrain conditions, and it takes a long time to reach the fire scene, and the risk of putting out the fire is great. Therefore, it is urgent to develop a long-distance fire extinguishing equipment that can implement long-distance fighting and efficiently prevent the spread of fire to control the fire fighting opportunity, gain time advantage, reduce close risk, greatly improve the efficiency of forest fire fighting, and protect the safety of fire fighting personnel and national forest resources. SUMMARY

[0004] In view of the above, the present application provides a modular multi-tube fire extinguishing device which adopts a modular design concept and can be quickly transported to the fire scene for assembly and use.

[0019] The trunnion is rotatably connected to the launcher, and the launch height adjustment module is connected to the gear-arc transmission.

[0020] In some embodiments of the present invention, the disassembly and assembly module includes:

[0021] Connector for connection to the multi-tube transmitter module;

[0022] The slide rail is connected to the connector and has multiple limit slots.

[0023] The locking seat for connecting the sight has a locking strip that mates with the limit slot;

[0024] Locking block;

[0025] The locking seat and locking block work together to be detachably connected to the slide rail.

[0028] One side of the locking block faces the locking seat and has a third inclined surface and a fourth inclined surface. The third inclined surface is used in conjunction with the second inclined surface, and the fourth inclined surface is used in conjunction with the first inclined surface.

[0029] In some embodiments of the present invention, the locking seat and the locking block are connected by a locking shaft, and one end of the locking shaft is threaded with a knob after passing through the locking seat and the locking block.

[0030] In some embodiments of the present invention, the launch altitude adjustment module includes:

[0031] Height adjustment handwheel, mounted on the launch pad;

[0032] The drive shaft has an output gear connected to one end, which can mesh with the tooth arc;

[0033] The worm gear is mounted on the drive shaft;

[0034] The worm gear is connected to the height adjustment handwheel;

[0035] The housing is penetrated by the drive shaft, and the side wall of the housing has a strip-shaped hole of a predetermined length;

[0036] The limiting ring is threaded to the drive shaft, and multiple insertion holes are distributed circumferentially on the circumferential sidewall of the limiting ring.

[0037] The limiting pin passes through the strip hole and is inserted into the socket.

[0038] In some embodiments of the present invention, there are two limiting rings, and the two limiting rings are connected to the drive shaft by threads with opposite directions.

[0039] Secondly, the present invention provides a modular multi-tube fire extinguishing device, wherein the output gear can engage or disengage with the tooth arc;

[0040] There are two limit rings and two limit pins. The two limit rings are the first limit ring and the second limit ring, and the two limit pins are the first limit pin and the second limit pin.

Then, the height adjustment handwheel is rotated to move the first limiting ring upwards to any position. After the first limiting ring has moved upwards to any position, the second limiting pin is inserted into the second limiting ring. The output gear is moved upwards and re-engaged with the tooth arc, releasing the limitation on the combined frame. Then, the second limiting pin is inserted into the second limiting ring. Subsequently, the height adjustment handwheel is rotated to move the second limiting ring toward the first limiting ring. When the second limiting ring contacts the first limiting ring, the second limiting ring is blocked by the first limiting ring and cannot move upwards any further. The second limiting ring then moves to the desired position, thus completing the adjustment of the firing height of the fire extinguishing projectile directional tube.

[0046] Second, the modular multi-tube fire extinguishing device adopts a direct aiming method. Since it does not require the use of photoelectric sights and comparison scales for aiming and firing (the photoelectric sight is used to give the fire extinguishing device a viewpoint for aiming and calibration, the comparison scale is used to determine the distance to the target fire source, and then the elevation and elevation parameters are adjusted by referring to the corresponding firing table), it is more efficient, easier to operate, and does not require long-term professional training for users.

[0047] Third, compared with the original fixed installation method of the sight, the setting of the disassembly and assembly module can make the disassembly and assembly of the sight convenient and quick, effectively protecting the safety of the sight and improving the service life of the sight (when the fire extinguishing shell is launched, there will be a back spray and a tail flame. The back spray has a great impact energy, and the tail flame gas has the characteristics of high temperature, high pressure and high corrosiveness. If the sight is not removed when the fire extinguishing shell is launched, it will easily cause damage to the sight or affect the service life of the sight).

[0076] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0077] Example 1

[0078] Please refer to Figures 1 to 13 This embodiment provides a modular multi-tube fire extinguishing device, which includes a launcher 1, a multi-tube launch module 2, an aiming module 3, a disassembly and assembly module 4, a launch azimuth adjustment module, and a launch height adjustment module.

[0079] The launcher 1 is roughly U-shaped, and the base 11 is rotatably connected to the bottom of the launcher 1.

[0080] The multi-barrel launcher module 2 is used to launch fire extinguishing projectiles; the multi-barrel launcher module 2 includes a combined frame 21, a fire extinguishing projectile directional tube 22, and a tailstock 23.

[0081] The combined frame 21 is rotatably connected to the launcher 1 and is used to fix the fire extinguishing projectile directional tube 22. The combined frame 21 includes a first frame plate 211, a second frame plate 212, a third frame plate 213, and a fourth frame plate 214 that are connected in sequence by bolts to form a rectangular frame structure. The second frame plate 212 and the fourth frame plate 214 are each connected to a trunnion 2121 by bolts in the middle. A toothed arc 2122 is fixed on the second frame plate 212 by bolts. The trunnion 2121 is rotatably connected to the launcher 1. The launch height adjustment module is driven by the toothed arc 2122. The launch height adjustment module can drive the combined frame 21 to rotate through the toothed arc 2122.

[0082] Both the second frame plate 212 and the trunnion 2121 are provided with connecting discs 2125, and the connecting discs 2125 on the second frame plate 212 and the trunnion 2121 are connected by bolts.

[0083] The toothed arc 2122 is connected to the arc plate 2123. Both the second frame plate 212 and the arc plate 2123 have three connecting screw holes (not marked in the figure). The toothed arc 2122 is connected to the second frame plate 212 by bolts and connecting screw holes on the arc plate 2123.

[0084] The second frame plate 212 is provided with an arc-shaped strip 2124. The arc-shaped strip 2124 has the same curvature as the arc plate 2123 and is located between the connecting screw hole on the second frame plate 212 and the connecting plate 2125 on the second frame plate 212. The arc-shaped strip 2124 can fit with the arc plate 2123, thereby facilitating the installation of the arc plate 2123 and the toothed arc 2122 on the second frame plate 212.

[0085] The second frame plate 212 and the fourth frame plate 214 have several weight-reducing holes 2126.

[0086] There are 16 fire extinguishing shell directional tubes 22, used for loading and launching fire extinguishing shells. The fire extinguishing shell directional tubes 22 pass through the first frame plate 211 and the third frame plate 213. Two locking nuts 221 are threaded onto the fire extinguishing shell directional tubes 22. The first frame plate 211 and the third frame plate 213 are located between the two locking nuts 221. The two locking nuts 221 facilitate the fixing of the fire extinguishing shell directional tubes 22 onto the combined frame 21. When the launching height adjustment module drives the combined frame 21 to rotate through the toothed arc 2122, the fire extinguishing shell directional tubes 22 rotate with the combined frame 21, thereby realizing the adjustment of the launching height.

[0087] The tailstock 23 is installed at the end of the fire extinguishing bomb directional tube 22 by an interference fit. The tailstock 23 is annular and is provided with a retractable elastic pin 231. One end of the elastic pin 231 can protrude from the inside of the tailstock 23 to restrict the movement of the fire extinguishing bomb loaded in the fire extinguishing bomb directional tube 22.

[0088] The tailstock 23 is equipped with a socket 232 and a cutter (not shown in the figure); the socket 232 is used to connect to the plug on the fire extinguishing bomb, the plug is connected to the fire extinguishing bomb through a wire, and the cutter is located near the wire and is used to cut the wire during the firing of the fire extinguishing bomb.

[0089] Based on the above, when loading the fire extinguishing bomb, the fire extinguishing bomb is inserted from the end of the fire extinguishing bomb directional tube 22. After the fire extinguishing bomb is in place, the elastic locking pin 231 engages with the corresponding structure on the fire extinguishing bomb to restrict its movement. When the fire extinguishing bomb is launched, it flies out and pulls the power line (during this process, the fire extinguishing bomb can overcome the resistance of the elastic locking pin 231). The power line is cut by a cutter so that the fire extinguishing bomb can be better separated from the fire extinguishing bomb directional tube 22.

[0090] The aiming module 3 includes a highly integrated aiming device 31, which employs intelligent aiming technology and integrates infrared, white light, rangefinding, elevation difference correction, tilt compensation, and automatic calculation techniques. It allows for one-click, all-weather, and rapid target observation and aiming, and automatically calculates the required aiming angle and fuse setting data. Simultaneously, the infrared function of the aiming device 31 can be used to quickly assess the fire extinguishing effect and the situation of personnel at the fire scene, providing data support for subsequent operations.

[0091] The disassembly module 4 is used to install the sight 31 onto the combined frame 21; the disassembly module 4 includes a connector 41, a slide rail 42, a locking seat 43, a locking block 44, a locking shaft 45, and a knob 46.

[0092] The connector 41 is fixed to the end of the trunnion 2121 by bolts. Specifically, the connector 41 has a circular connecting part 411 and a plate-shaped extension part 412. The connecting part 411 is connected to the end of the trunnion 2121 by bolts.

[0093] The slide rail 42 is bolted to the extension 412 of the connector 41; the slide rail 42 has multiple limiting slots 421; the slide rail 42 has a first inclined surface 422 and a V-shaped block 423 on opposite sides.

[0094] The locking seat 43 includes an L-shaped mounting part 431 and a locking part 432 that are connected to each other; the mounting part 431 is connected to the aiming device 31 by bolts, and one side of the mounting part 431 has a locking strip (not shown in the figure, as it is obscured due to the viewing angle) that cooperates with the limiting slot 421; the top of the mounting part 431 has a second inclined surface 4311; the locking part 432 has a V-groove 4321 that matches the V-block 423.

[0095] One side of the locking block 44 faces the locking seat 43 and has a third inclined surface 441 and a fourth inclined surface 442. The third inclined surface 441 and the fourth inclined surface 442 together form a figure-eight shape. The third inclined surface 441 is used in conjunction with the second inclined surface 4311, and the fourth inclined surface 442 is used in conjunction with the first inclined surface 422.

[0096] There are two locking shafts 45. The locking shafts 45 are used to connect the locking seat 43 and the locking block 44, so that the locking seat 43 and the locking block 44 are installed on the slide rail 42. One end of the locking shaft 45 passes through the locking seat 43 and the locking block 44 and is threaded to the knob 46. Tightening the knob 46 can fasten the locking seat 43 and the locking block 44 to the slide rail 42.

[0097] There are also two knobs 46. Knob 46 is cam-shaped and has anti-slip texture.

[0098] Based on the above, when installing the sight 31 onto the combined frame 21 via the disassembly and assembly module 4, the slide rail 42 can be fixed to the end of the trunnion 2121 via the connector 41. Then, the locking strip on the locking seat 43 can be inserted into the limiting slot 421 on the slide rail 42. The locking seat 43 and the locking block 44 can be fastened to the slide rail 42 via the locking shaft 45 and the knob 46. Finally, the sight 31 can be fixed onto the mounting part 431 of the locking seat 43 to achieve quick installation of the sight 31.

[0099] The launch orientation adjustment module is used to rotate the launcher 1 relative to the base 11 at a certain angle in the horizontal plane. The launch orientation adjustment module includes an orientation adjustment handwheel 51 installed on the launcher 1. The orientation adjustment handwheel 51 is connected to the base 11 in a transmission manner. Rotating the orientation adjustment handwheel 51 can adjust the orientation of the launcher 1, thereby adjusting the orientation of the multi-tube launch module 2.

[0100] The launch height adjustment module is located close to the launch azimuth adjustment module. The launch height adjustment module is used to rotate the combined frame 21 relative to the launcher 1 at a certain angle in the vertical plane. The launch height adjustment module includes a height adjustment handwheel 61 installed on the launcher 1. The height adjustment handwheel 61 is connected to the toothed arc 2122 on the combined frame 21 through a transmission mechanism. Rotating the height adjustment handwheel 61 can adjust the launch height of the combined frame 21 and the fire extinguishing projectile directional tube 22.

[0101] The transmission mechanism is located inside the launcher 1; the transmission mechanism includes a transmission shaft 62, a worm gear 63, a worm 64, a housing 65, a limiting ring 66, and a limiting pin.

[0102] One end of the drive shaft 62 is connected to an output gear 621, which can mesh with the tooth arc 2122.

[0103] The worm gear 63 is mounted on the drive shaft 62.

[0104] The worm gear 64 is connected to the height adjustment handwheel 61; the drive shaft 62 is connected to the height adjustment handwheel 61 via the worm wheel 63 and the worm gear 64. A protective housing 67 is provided around the worm wheel 63 and the worm gear 64.

[0105] The housing 65 is penetrated by the drive shaft 62, and the side wall of the housing 65 has a strip hole 651 of a predetermined length.

[0106] The limiting ring 66 is threadedly connected to the drive shaft 62, and the circumferential sidewall of the limiting ring 66 has multiple insertion holes 661 distributed circumferentially.

[0107] A limiting pin (not shown in the figure) passes through the strip hole 651 and is inserted into the insertion hole 661 of the limiting ring 66.

[0108] The working principle of the above transmission mechanism is as follows: First, the limiting pin is inserted through the slot 651 into the insertion hole 661 of the limiting ring 66. Then, the height adjustment handwheel 61 is rotated, and the transmission shaft 62 is driven to rotate after being reduced in speed by the worm gear 63 and the worm 64. The transmission shaft 62 then drives the limiting ring 66 to move longitudinally (the limiting ring 66 cannot rotate due to the cooperation of the limiting pin and the slot 651). When the movement of the limiting ring 66 is blocked by the slot 651, the limiting ring 66 reaches the limit position, which facilitates the rapid adjustment of the firing height of the fire extinguishing bullet directional tube 22 to the limit position. In other words, it forms a memory of the limit position, which is convenient for repeated adjustment to the limit position.

[0109] Furthermore, in this embodiment, there are two limiting rings 66 and two corresponding limiting pins. The two limiting rings 66 are connected to the drive shaft 62 by threads with opposite directions of rotation. This can shorten the longitudinal movement of the limiting rings 66, so as to adjust the launch height of the fire extinguishing bullet directional tube 22 to the limit position more quickly.

[0110] The aforementioned modular multi-tube fire extinguishing system has at least the following beneficial effects:

[0111] I. Modular multi-tube fire extinguishing device adopts a modular design concept, which can be quickly transported to the fire scene for assembly and use. Through the modular multi-tube fire extinguishing device, long-distance fire fighting can be carried out, effectively preventing the spread of fire, so as to control the timing of fire fighting, gain time advantage, reduce the risk of close approach, greatly improve the efficiency of forest fire fighting, and protect the safety of firefighters and national forest resources.

[0112] Second, the modular multi-tube fire extinguishing device adopts a direct aiming method. Since it does not require the use of photoelectric sights and comparison scales for aiming and firing (the photoelectric sight is used to give the fire extinguishing device a viewpoint for aiming and calibration, the comparison scale is used to determine the distance to the target fire source, and then the elevation and elevation parameters are adjusted by referring to the corresponding firing table), it is more efficient, easier to operate, and does not require long-term professional training for users.

[0113] Third, the multi-barrel launcher module 2 has a simple structure, is easy to use, has high reliability, long service life, and is easy to maintain; the combined frame 21 is assembled to reduce weight and facilitate installation; it can be mounted on any platform with a corresponding interface via trunnions 2121; the multi-barrel launcher module 2 has a firing interval of 120 milliseconds and a fast firing rate, capable of firing 16 fire extinguishing shells within 2 seconds, covering a fire area of ​​more than 400 square meters, achieving cluster suppression and wide coverage, thereby effectively preventing reignition.

[0114] Fourth, compared with the original fixed installation method of the sight 31, the disassembly and assembly module 4 can be set up to facilitate the disassembly and assembly of the sight 31, effectively protecting the safety of the sight and improving the service life of the sight (when the fire extinguishing shell is launched, there will be a back spray and a tail flame. The back spray has a great impact energy, and the tail flame gas has the characteristics of high temperature, high pressure and high corrosiveness. If the sight is not removed when the fire extinguishing shell is launched, it will easily cause damage to the sight or affect the service life of the sight).

[0115] 5. The assembly and disassembly module 4 can ensure installation accuracy through the cooperation of V-block 423 and V-groove 4321, the cooperation of third inclined surface 441 and second inclined surface 4311, and the cooperation of fourth inclined surface 442 and first inclined surface 422.

[0116] VI. The launch altitude adjustment module is positioned close to the launch azimuth adjustment module for easy operation by users.

[0117] VII. The launch height adjustment module has an extreme position memory function, which can quickly and efficiently adjust the launch height of the fire extinguishing projectile directional tube 22 to the extreme position.

[0118] Example 2

[0119] Please refer to Figures 1 to 13 ,as well as Figure 14 Unlike Embodiment 1, in this embodiment, the two limiting rings are a first limiting ring 71 and a second limiting ring 72, and the two limiting pins (not shown in the figure) are a first limiting pin and a second limiting pin, respectively. The first limiting pin corresponds to the first limiting ring 71, and the second limiting pin corresponds to the second limiting ring 72. The first limiting ring 71 and the second limiting ring 72 are connected to the transmission shaft 62 by threads with the same direction of rotation. In addition, in this embodiment, the output gear 621 can move a certain distance along the axial direction of the limiting pin. During the axial movement of the output gear 621 along the limiting pin, the output gear 621 can engage or disengage with the tooth arc 2122.

[0120] In this embodiment, the method of using the modular multi-tube fire extinguishing device (the working principle of the transmission mechanism) is as follows:

[0121] In use, first, use an external device to limit the position of the combined frame 21. Then, use the external device to lower the output gear 621, disengaging it from the tooth arc 2122. Next, insert the first limiting pin into the insertion hole 661 of the first limiting ring 71. Then, rotate the height adjustment handwheel 61 to move the first limiting ring 71 to any position. The second limiting ring 72, not being engaged with the second limiting pin, will not move upward. After the first limiting ring 71 has moved to any position (this position is used as a memory position), insert the second limiting pin into the insertion hole 661 of the second limiting ring 72, moving the output gear 621 upward to re-engage with the tooth arc 2122, thus releasing the combined frame. After setting the limit pin at position 21, insert the second limit pin into the insertion hole 661 of the second limit ring 72. Then, rotate the height adjustment handwheel 61 to move the second limit ring 72 toward the first limit ring 71. When the second limit ring 72 contacts the first limit ring 71, the second limit ring 72 is blocked by the first limit ring 71 and cannot move further upward (the frictional resistance between the second limit ring 72 and the first limit ring 71 is small, and after the second limit ring 72 contacts the first limit ring 71, the first limit ring 71 can still rotate relative to the second limit ring 72). The second limit ring 72 then moves to the desired position, thus completing the adjustment of the firing height of the fire extinguishing bullet guide tube 22. In the process of repeatedly adjusting the firing height of the fire extinguishing bullet guide tube 22, the firing height of the fire extinguishing bullet guide tube 22 can be quickly adjusted to the same position.

[0122] Compared with Embodiment 1, the transmission mechanism of this embodiment has at least the following beneficial effects:

[0123] In this embodiment, any position can be used as a memory position. During the repeated adjustment of the launch height of the fire extinguishing bullet guide tube 22, the launch height of the fire extinguishing bullet guide tube 22 can be quickly adjusted to the same position (i.e., the memory position).

[0124] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
