Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment technology, and specifically to a mobile water gun machine. Background Technology

[0002] At the fire scene, firefighters, wearing flame-retardant and moisture-resistant suits, hold water hoses and spray high-pressure water at the flames from the closest possible position to extinguish the fire quickly and minimize damage. However, high-pressure water hoses have the following disadvantages: 1. High-temperature exposure: When firefighters are close to the fire, they cannot avoid the intense heat, even wearing flame-retardant suits. 2. High physical exertion: The large volume and pressure of the water hose create a strong recoil, requiring firefighters to use their strength to counteract it. Prolonged firefighting operations result in significant physical exhaustion. 3. High safety risks: During close-range firefighting, unknown hazardous materials within the fire area may explode under the intense heat of the flames, causing injury or even death to firefighters.

[0069] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0070] The water gun mobile device 100 of an embodiment of the present invention will now be described with reference to the accompanying drawings. Figures 1 to 9As shown, the water gun moving machine 100 according to an embodiment of the present invention includes a water gun 1, a fire hose 11, a gun barrel 2, an extension tube 3, a clamping mechanism 5, and a driving device 8.

[0071] The water gun 1 is connected to the fire hose 11. The nozzle 2 is connected to the water gun 1 to secure it. Specifically, the water gun 1 is a high-pressure water gun, which is connected to the nozzle 2 via an internal snap-fit ​​connector. One end of the fire hose 11 is connected to the water gun 1, and the other end of the fire hose 11 is connected to a fire truck or a high-pressure water source for spraying water. The fire hose 11 consists of multiple sections.

[0072] The first end of the extension tube 3 is connected to the gun barrel 2, and the fire hose 11 can be placed inside the gun barrel 2 and the extension tube 3. The clamping mechanism 5 is used to clamp the second end of the extension tube 3.

[0073] The drive device 8 includes a walking mechanism 81 and a moving arm 82. The walking mechanism 81 is connected to the moving arm 82 and can drive the moving arm 82 to move on the ground. The moving arm 82 is connected to the clamping mechanism 5 so as to drive the clamping mechanism 5 to move in the vertical direction.

[0074] According to an embodiment of the present invention, the water gun moving mechanism 100 is equipped with a gun barrel 2 and an extension tube 3, with the water gun 1, gun barrel 2, and extension tube 3 connected in sequence. This allows the water gun 1 to be moved by moving the extension tube 3 and gun barrel 2. The fire hose 11 can be placed inside the gun barrel 2 and extension tube 3, meaning the gun barrel 2 and extension tube 3 can support and limit the fire hose 11, allowing water to be supplied to the water gun 1 through the fire hose 11. During firefighting, firefighters do not need to hold the water gun 1; by controlling the extension tube 3, they can extinguish the fire from a distance from the fire scene, thus improving safety during firefighting.

[0075] The movable arm 82 is connected to the clamping mechanism 5 to move the clamping mechanism 5 vertically. The clamping mechanism 5 is used to clamp the extension tube 3, thereby allowing the movable arm 82 to move the extension tube 3, the gun barrel 2, and the water gun 1 vertically, facilitating fire extinguishing. The traveling mechanism 81 of the drive device 8 can move the movable arm 82 on the ground, facilitating access to the fire scene and improving fire extinguishing efficiency.

[0076] Therefore, the water gun mobile unit 100 according to an embodiment of the present invention has the advantage of improving the safety and efficiency of fire extinguishing.

[0077] like Figures 1 to 9 As shown, in some embodiments, the water gun moving machine 100 also includes a rotary drive mechanism 6 and a tilting rotary joint 7.

[0078] The rotary drive mechanism 6 is mounted on the moving arm 82 and is connected to the clamping mechanism 5 to drive the clamping mechanism 5 to rotate. In other words, the rotary drive mechanism 6 can drive the clamping mechanism 5 to rotate, thereby causing the extension tube 3, the gun barrel 2, and the water gun 1 connected to the clamping mechanism 5 to rotate around the rotation axis of the rotating part of the rotary drive mechanism 6.

[0079] The extension tube 3 extends in a first direction, and the gun barrel 2 extends in a second direction, forming an angle between the first and second directions. The gun barrel 2 is located at the first end of the extension tube 3 via an inclined rotary joint 7, which can rotate the gun barrel 2. Specifically, the outlet of the water gun 1 faces away from the gun barrel 2 in the second direction, and the outlet of the water gun 1 forms an angle with the extension tube 3's extension direction; that is, the water gun 1 and the gun barrel 2 are inclined relative to the extension tube 3. The axis of the rotating part of the rotary drive mechanism 6 is aligned with the axis of the extension tube 3, so that when the rotary drive mechanism 6 rotates the extension tube 3, it can change the position of the water gun 1. When the inclined rotary joint 7 rotates, it can change the position of the water gun 1 and also change the angle between the extension tube 3 and the gun barrel 2 (water gun 1), i.e., change the angle between the first and second directions. The rotary drive mechanism 6 and the inclined rotary joint 7 cooperate to change the position of the water gun 1, making it easier for the outlet of the water gun 1 to face the nearby fire area, thus facilitating firefighting.

[0080] In some embodiments, the angle between the first direction and the second direction is greater than or equal to 35° and less than or equal to 55°, that is, the angle between the extension direction of the extension tube 3 and the extension direction of the gun barrel 2 is greater than or equal to 35° and less than or equal to 55°. For example, the angle between the first direction and the second direction is 45°.

[0081] like Figure 1 and Figure 2 As shown, in some embodiments, the drive device 8 further includes a frame 83 and a frame rotation mechanism 84. The frame 83 is rotatably mounted on the walking structure via the frame rotation mechanism 84, and the rotation axis of the frame rotation mechanism 84 is in the up-down direction.

[0082] The movable arm 82 includes a large rocker arm 821, a small rocker arm 822, a first hydraulic cylinder 823, a second hydraulic cylinder 824, a third hydraulic cylinder 825, and a connecting plate 826.

[0083] The large rocker arm 821 (rear end) is hinged to the frame 83, and the small rocker arm 822 (rear end) is hinged to the large rocker arm 821 (front end). The fixed part of the first hydraulic cylinder 823 is hinged to the frame 83, and the telescopic part of the first hydraulic cylinder 823 is hinged to the large rocker arm 821 (middle part), so that when the first hydraulic cylinder 823 telescopically extends or retracts, it can drive the large rocker arm 821 to rotate, so that the large rocker arm 821 (front end) can move in the vertical direction.

[0084] The fixed part of the second hydraulic cylinder 824 is hinged to the large rocker arm 821 (the middle bent part), and the telescopic part of the second hydraulic cylinder 824 is hinged to the small rocker arm 822 (the rear end part), so that when the second hydraulic cylinder 824 telescopically extends or retracts, it can drive the small rocker arm 822 to rotate, so that the small rocker arm 822 (the front end part) can move in the vertical direction.

[0085] The fixed part of the third hydraulic cylinder 825 is hinged to the small rocker arm 822 (rear end), and the rotary drive mechanism 6 is hinged to the small rocker arm 822 (front end). The two ends of the connecting plate 826 are respectively hinged to the telescopic part of the third hydraulic cylinder 825 and the rotary drive mechanism 6. Thus, when the third hydraulic cylinder 825 telescopicates, the rotary drive mechanism 6 can be driven to rotate through the connecting plate 826, so that the rotary drive mechanism 6 can move in the vertical direction.

[0086] like Figures 1 to 4 As shown, in some embodiments, the rotary drive mechanism 6 includes a first motor 61, a load-bearing frame 62, a first disc 63, a second disc 65, and a first retaining ring 67.

[0087] The first shaft of the first motor 61 extends along a first direction. Specifically, the first motor 61 is the driver of the rotary drive mechanism 6, the first shaft is the rotating part of the rotary drive mechanism 6, and the axis of the first shaft is aligned with the axis of the extension cylinder 3. For example, the first motor 61 is a hydraulic motor.

[0088] The load-bearing frame 62 is mounted on the movable arm 82, and the first motor 61 is fixed to the load-bearing frame 62. Specifically, the first motor 61 is fixed to the movable arm 82 via the load-bearing frame 62. For example, the load-bearing frame 62 includes two first side plates and one first end plate. The first motor 61 is fixed to the first end plate. The two first side plates are hinged to the small rocker arm 822 (front end) via first pins, and the two first side plates are hinged to the two connecting plates 826 via second pins.

[0089] The first disk 63 has its axial direction in the first direction and a first through hole 64 extending through it in the first direction. The first disk 63 is fixed to the end of the support frame 62 away from the moving arm 82. Specifically, the thickness direction of the first disk 63 is in the first direction, and the first disk 63 serves as a limiting plate. The first rotating shaft of the first motor 61 passes through the first through hole 64. For example, the first disk 63 is detachably fixed to the first end plate of the support frame 62 by bolts.

[0090] The second disk 65 and the first retaining ring 67 are axially aligned in a first direction. The second disk 65 and the first retaining ring 67 define an annular first rotating groove 68, the opening of which faces inward. The first disk 63 is located within the first rotating groove 68. Specifically, the second disk 65 and the first retaining ring 67 are arranged opposite each other in the first direction, limiting the first disk 63 in the first direction. The second disk 65 and the first retaining ring 67 are rotatable relative to the first disk 63. For example, the annular body at the middle position of the second disk 65 defines a first passage 64. The first retaining ring 67 includes two sub-retaining rings and has a stepped groove. The first retaining ring 67 is threadedly connected to the second disk 65.

[0091] The second disc 65 has a second through hole 66 connected to the first rotating shaft. A keyway is provided within the second through hole 66. The first rotating shaft extends out of the first through hole 64 and engages within the second through hole 66 of the second disc 65 to drive the second disc 65 to rotate. The second disc 65 is connected to the clamping mechanism 5. Specifically, the first rotating shaft has a locking key that engages with the keyway within the second through hole 66. When the first rotating shaft rotates and drives the second disc 65 (and the first retaining ring 67) to rotate, it drives the clamping mechanism 5 to rotate, thereby causing the extension tube 3, the gun barrel 2, and the water gun 1, all connected to the clamping mechanism 5, to rotate around the rotation axis of the first rotating shaft.

[0092] like Figures 1 to 3 As shown, in some embodiments, the clamping mechanism 5 includes a first vertical frame 51, a first connecting rod 511, a second connecting rod 512, a second vertical frame 52, a third connecting rod 513, a fourth connecting rod 514, a third vertical frame 53, a first clamping head 54, a second clamping head 55, a first jack 58, a first hinge plate 581, and a second hinge plate 582.

[0093] The first vertical frame 51 is connected to the rotary drive mechanism 6. Specifically, the first vertical frame 61 is connected to the second disk 65.

[0094] Both ends of the first link 511 and the second link 512 are hinged to the first vertical frame 51 and the second vertical frame 52, respectively. The first link 511 and the second link 512 are arranged parallel to each other. Specifically, the first vertical frame 51 and the second vertical frame 52 are spaced apart in a first direction and connected to the second link 512 through the first link 511, so that the second vertical frame 52 can move relative to the first vertical frame 51 in a third direction. The parallel arrangement of the first link 511 and the second link 512 in a third direction can make the second vertical frame 52 more stable when it moves.

[0095] Both ends of the third link 513 and the fourth link 514 are hinged to the first vertical frame 51 and the third vertical frame 53, respectively, and the third link 513 and the fourth link 514 are arranged parallel to each other. Specifically, the third vertical frame 53 and the second vertical frame 52 are arranged opposite each other in a third direction. The first vertical frame 51 and the third vertical frame 53 are spaced apart in a first direction and connected to the second link 512 through the first link 511, so that the third vertical frame 53 can move relative to the first vertical frame 51 in a third direction. The parallel arrangement of the third link 513 and the fourth link 514 in a third direction can make the second vertical frame 52 more stable when it moves.

[0096] The first clamping head 54 is connected to the second vertical frame 52 via the first clamping arm 56, and the second clamping head 55 is connected to the third vertical frame 53 via the second clamping arm 57. The first clamping head 54 and the second clamping head 55 are arranged opposite each other in a third direction, with the first direction forming an angle with the third direction. Specifically, the first clamping head 54 has a first clamping groove, and the second clamping head 55 has a second clamping groove. The first and second clamping grooves are arranged opposite each other and both extend along the first direction. The extension tube 3 is suitable for placement within the first and second clamping grooves. This ensures that when the third vertical frame 53 and the second vertical frame 52 move relative to each other, the first clamping head 54 and the second clamping head 55 are close to each other, so that the first and second clamping grooves clamp and fix the extension tube 3. For example, the first direction is perpendicular to the third direction.

[0097] The fixed part of the first jack 58 is hinged to the first vertical frame 51, and the first jack 58 is located between the third vertical frame 53 and the second vertical frame 52 in the third direction. The two ends of the first hinge plate 581 are respectively hinged to the telescopic part of the first jack 58 and the first connecting rod 511, and the two ends of the second hinge plate 582 are respectively hinged to the telescopic part of the first jack 58 and the fourth connecting rod 514. Specifically, the first hinge plate 581 and the second hinge plate 582 are located on both sides of the first jack 58 in the third direction. When the first jack 28 extends or retracts, it can drive the first hinge plate 581 and the second hinge plate 582 to move, thereby causing the first clamp 54 and the second clamp 55 to clamp or loosen the extension tube 3.

[0098] like Figures 1 to 3 As shown, in some embodiments, each of the first link 511, the second link 512, the third link 513, and the fourth link 514 is in multiple forms, thereby improving the stability of the clamping mechanism 5. For example, each of the first link 511, the second link 512, the third link 513, and the fourth link 514 is in quadruplicate, with the two ends of the first hinge plate 581 hinged to the telescopic portion of the first jack 58 and the two first links 511, respectively, and the two ends of the second hinge plate 582 hinged to the telescopic portion of the first jack 58 and the two fourth links 514, respectively.

[0099] like Figure 5 and Figure 6 As shown, in some embodiments, the extension tube 3 can extend and retract in the first direction. Therefore, the length of the extension tube 3 can be controlled to maintain a safe distance between the water gun 1 and the personnel, and to facilitate the proximity of the water gun 1 to the fire scene. This allows for the most reasonable and effective location to spray water to extinguish the fire, enabling firefighters to carry out firefighting operations from a distance away from the fire point, thereby reducing the harm to firefighters from the high temperature of the flames. Furthermore, the longer length of the extension tube 3 allows the water gun 1 to be moved a greater distance by swinging the extension tube 3, thus increasing the travel distance of the water gun 1.

[0100] like Figure 5 and Figure 6 As shown, in some embodiments, the extension cylinder 3 includes a plurality of floating cylinders 31, a plurality of locking sleeves 33 and a plurality of opening sleeves 34.

[0101] Multiple floating cylinders 31 are sequentially arranged (nested) from the inside out, with adjacent floating cylinders 31 slidably connected. Each floating cylinder 31 extends along a first direction. Multiple locking sleeves 33 cooperate one-to-one with multiple open sleeves 34. Adjacent floating cylinders 31 are fixedly connected by cooperating locking sleeves 33 and open sleeves 34. The locking sleeves 33 have an annular structure. The fire hose 11 is located inside the multiple floating cylinders 31. Therefore, when it is necessary to increase the length of the extension tube 3, the corresponding floating cylinder 31 can be extended out, and then the extended floating cylinder 31 can be fixed by cooperating locking sleeves 33 and open sleeves 34.

[0102] The end of the first floating cylinder among the multiple floating cylinders 31 can form the second end of the extension cylinder 3. Specifically, the first floating cylinder is the outermost of the multiple floating cylinders 31, and the first floating cylinder is adapted to be fixed on the first clamping head 54 and the second clamping head 55 of the clamping mechanism 5. The first floating cylinder is provided with a bend 32, which is used to connect to the fire hose 11. The bend 32 is inclined relative to the first floating cylinder (floating cylinder 31) and is located on the side of the first floating cylinder adjacent to the clamping mechanism 5. The fire hose 11 can be placed in or connected to the fire hose 11. The bend 32 guides the fire hose 11 to prevent the fire hose 11 from interfering with the clamping structure 5. For example, the bend 32 is detachably installed in the first floating cylinder. The bend 32 has an internal snap-fit ​​connector for connecting the fire hose 11 to a fire truck or high-pressure water source.

[0103] The end of the second floating cylinder in the plurality of floating cylinders 31 can form the first end of the extension cylinder 3. The second floating cylinder is connected to the gun barrel 2 through the tilting rotary joint 7. The second floating cylinder is the innermost one of the plurality of floating cylinders 31.

[0104] In some embodiments, the floating cylinder 31 may be made of high-strength steel or a lightweight, high-strength material, which allows the floating cylinder 31 to be made longer and more sections of floating cylinder 31 to be installed.

[0105] like Figure 9 As shown, the locking sleeve 33 includes an internal thread section 331, a tapered hole section 332, and a through hole section 333 connected sequentially in a first direction. Specifically, the internal thread section 331, the tapered hole section 332, and the through hole section 333 are all annular structures, and are connected sequentially in the first direction along the direction adjacent to the water gun 1.

[0106] The internal thread section 331 can be threadedly connected to the end of the outermost of the two connected floating cylinders 31. Specifically, the inner diameter of the internal thread section 331 is adapted to the outer diameter of the outermost of the two connected floating cylinders 31. The thread on the inner wall of the internal thread section 331 can be threadedly connected to the outer peripheral surface of the outermost of the two connected floating cylinders 31 adjacent to the end of the water gun 1.

[0107] The tapered section 332 has a tapered hole with the axial direction in the first direction, and the inner diameter of the tapered hole decreases in the first direction away from the clamping mechanism 5. Specifically, the inner diameter of the tapered hole is smaller than the inner diameter of the internal thread section 331, and the tapered section 332 is a guide and limiting section.

[0108] A through-hole section 333 is annularly disposed on the inner side of one of the two connected floating cylinders 31. The through-hole section 333 is slidably connected to the inner side of the two connected floating cylinders 31. The through-hole section 333 has an annular sealing groove 334 facing inward, and a sealing element is placed in the sealing groove 334. Specifically, the sealing element can be a sealing ring. The sealing ring is located in the sealing groove 334 to limit the sealing ring in a first direction. The sealing ring is located on the through-hole section 333 and the inner side of the two connected floating cylinders 31, thereby improving the sealing performance.

[0109] The open sleeve 34 is an arc-shaped elastic element. The two ends of the open sleeve 34 can be adjacent to each other circumferentially. The open sleeve 34 is located within the corresponding locking sleeve 33. The open sleeve 34 is provided on the inner one of the two connected floating cylinders 31 to lock the inner one of the two connected floating cylinders 31. Specifically, the open sleeve 34 is an arc-shaped clamping structure with an opening. The circumferential definition of the open sleeve 34 allows the two ends of the opening to be adjacent to each other circumferentially, thereby reducing the inner diameter of the open sleeve 34 to lock the inner one of the two connected floating cylinders 31.

[0110] The open sleeve 34 includes a sleeve section 341 and a conical sleeve section 342 connected in sequence in the first direction.

[0111] The sleeve section 341 is used to abut against the end of one of the two connected floating cylinders 31 located on the inner side. Specifically, the sleeve section 341 is located on the side of the conical sleeve section 342 facing away from the water gun 1 in the first direction.

[0112] The outer diameter of the tapered sleeve section 342 is less than or equal to the outer diameter of the sleeve section 341. The outer diameter of the tapered sleeve section 342 decreases in the first direction away from the clamping mechanism 5. The outer wall surface of the tapered sleeve section 342 mates with the inner wall surface of the tapered hole section 332. Thus, when the locking sleeve 33 is threadedly connected to the outer end of the two floating cylinders 31 and rotates continuously, the outer wall surface of the tapered sleeve section 342 can guide the inner wall surface of the tapered hole section 332, so that the two ends of the open sleeve 34 in the circumferential direction can be adjacent to each other in the circumferential direction and clamp the inner one of the two floating cylinders 31, thereby fixing the two floating cylinders 31 together.

[0113] In some embodiments, the bottom end of the inner floating cylinder 31 in the two connected floating cylinders 31 is provided with a piston section, and the diameter of the piston section is larger than the inner diameter of the through hole section 333 in the locking sleeve 33, for fitting a wear-resistant ring so that the inner floating cylinder 31 cannot be pushed out from the corresponding outer floating cylinder 31.

[0114] like Figures 5 to 8 As shown, the tilting rotary joint 7 includes a tilting ring 71, a second retaining ring 73, a connecting gear disk 72, and a first motor 75.

[0115] An inclined ring 71 is disposed at the first end of the extension cylinder 3; a first motor 75 is disposed at the first end of the extension cylinder 3, and a reinforcing rib 76 is provided between the first motor 75 and the first end of the extension cylinder 3. Specifically, the inclined ring 71 is disposed at the end of the first floating cylinder near the water gun 1, and is arranged around the periphery of the first floating cylinder. The first motor 75 is fixed to the end of the first floating cylinder near the water gun 1 by the reinforcing rib 76. The thickness direction (axial direction) of the inclined ring 71 is consistent with the second direction (the extension direction of the gun barrel 2). For example, the port of the inclined ring 71 at the first end of the extension cylinder 3 is an oblique opening that mates with the inclined ring 71, and the port surface of the inclined ring 71 at the first end of the extension cylinder 3 is perpendicular to the second direction.

[0116] The connecting gear disk 72 is located at the end of the gun barrel 2 away from the water gun 1, and the outer peripheral side of the connecting gear disk 72 is provided with teeth (arranged circumferentially).

[0117] The second retaining ring 73 is disposed on the connecting gear disk 72 and defines an annular second rotating groove 74 with the connecting gear disk 72. The opening of the second rotating groove 74 faces inward, and the tilting ring 71 is located within the second rotating groove 74. The connecting gear disk 72 and the second retaining ring 73 can rotate relative to the tilting ring 71. Specifically, the thickness direction of the second retaining ring 73 and the connecting gear disk 72 is the second direction. The second retaining ring 73 and the connecting gear disk 72 are located on both sides of the tilting ring 71 in the second direction so that the second retaining ring 73 and the connecting gear disk 72 limit the tilting ring 71 in the second direction. For example, the second retaining ring 73 has a stepped groove, the second retaining ring 73 includes two sub-retaining rings, and the second retaining ring 73 is bolted to the connecting gear disk 72.

[0118] The first motor 75 is equipped with a first gear 77, which meshes with a connecting gear disk 72 to drive the connecting gear disk 72 to rotate. Thus, the rotation of the first motor 75 drives the connecting gear disk 72 to rotate, thereby driving the gun barrel 2 to rotate, and consequently, the water gun 1 to rotate, thus changing the orientation of the water gun 1. It can also change the angle between the extension tube 3 and the gun barrel 2 (water gun 1), that is, change the angle between the first direction and the second direction.

[0119] In some embodiments, the excavator's bucket can be removed to serve as at least part of the drive unit 8. That is, the drive unit 8 can be an excavator with the bucket removed to reduce cost and difficulty. The existing excavator is used to drive the rotary drive mechanism 6, facilitating the vertical movement of the extension cylinder 3, the gun barrel 2, and the water gun 1. When some general-purpose excavators are selected for use as firefighting equipment, the bucket can be removed from the excavator 1, and the first motor 61 (hydraulic motor) and the first jack 58 can be connected to the excavator's hydraulic system using high-pressure hoses. This allows the excavator to be operated, causing the first motor 61 to rotate, driving the clamping mechanism 5 to rotate, and enabling the first jack 58 to reciprocate. After the excavator reaches the fire scene, the extension cylinder 6 can be clamped onto the clamping mechanism 5, the locking sleeves 33 can be loosened, and the corresponding floating cylinder 31 can be pulled out to the specified length. Afterwards, tighten each floating cylinder 31 and secure it in the designated position using the open sleeve 34. Connect the first motor 75 to the power supply inside the excavator using an electrical wire, and connect the fire hose 11 to the fire truck or high-pressure water source. Then operate the excavator to lift the extension cylinder 3, swing the water gun 1 to the fire area, connect the high-pressure water, and the fire extinguishing operation can begin. At this time, the distance between the water gun 1 and the excavator is relatively far, allowing firefighters to extinguish the fire from a distance away from the fire point, thereby reducing safety hazards and mitigating the high temperature.
