Description

Technical Field

[0001] The utility model relates to fire-fighting equipment, in particular to a rotating water gun for fire-fighting. Background Art

[0002] When extinguishing a fire, in order to ensure personnel safety, before understanding the specific situation of the fire scene, water guns are usually used to spray water into the building. However, the water cannot be directly aimed at the fire point, and the spraying area is limited, which has a poor effect in suppressing the spread of the fire. Therefore, a water gun extension tube was invented, which can extend the water gun directly into the building. Although it can be closer to the fire point, the water gun spray position is fixed, and its coverage is still small. In addition, the spraying angle is fixed, which is less suitable for the location of the fire point. Utility Model Content

[0003] The utility model aims to provide a rotating water gun for fire fighting, which can effectively solve the problems of small coverage range and difficulty in adjusting the spray angle of the existing water guns during fire fighting.

[0004] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0005] A rotating water gun for fire fighting comprises an extension tube and a bracket supporting the extension tube, wherein the extension tube comprises a hinged first tube body and a second tube body, a connecting tube is provided between the head of the second tube body and the tail of the first tube body, an angle fixing device is also provided between the first tube body and the second tube body, a spiral nozzle is provided at the head of the first tube body, a water hose interface is provided at the tail of the second tube body, and the bracket is connected to the second tube body.

[0006] In the above-mentioned rotating water gun for fire fighting, the angle fixing device includes a first fixing rod and a second fixing rod, one end of the first fixing rod is rotatably connected to the first tube body, one end of the second fixing rod is rotatably connected to the second tube body, and the other end of the first fixing rod and the other end of the second fixing rod are connected by bolts.

[0007] In the above-mentioned rotating water gun for fire fighting, a damping mechanism is provided between the other end of the first fixing rod and the other end of the second fixing rod.

[0008] In the above-mentioned rotating water gun for fire fighting, the damping mechanism includes at least one friction plate, the friction plate is arranged between the first fixing rod and the second fixing rod, and the bolt passes through the friction plate.

[0009] In the above-mentioned rotating water gun for fire fighting, the damping mechanism includes a first damping plate and a second damping plate whose end surfaces are closely attached to each other, and the first damping plate and the second damping plate are both provided with teeth meshing with each other.

[0010] In the above-mentioned rotating water gun for fire fighting, the bracket includes a clamp and a support leg, the clamp is sleeved on the second tube body, and the support leg is rotatably connected to the clamp.

[0011] In the above-mentioned rotating water gun for fire fighting, the clamp is located between the center of gravity of the extension pipe and the spiral nozzle.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] By connecting the first tube body and the second tube body, the angle of the spiral nozzle can be adjusted within a certain range, solving the problem that the current water gun has a small coverage range and is difficult to adjust the spray angle when extinguishing a fire. The extension tube is divided into a first tube body and a second tube body, and the first tube body and the second tube body are hinged, so that the first tube body can swing within a certain range relative to the second tube body, so that the water sprayed from the spiral nozzle has a larger adjustment angle, and the angle fixing device can be used to fix the relative position of the first tube body and the second tube body, and spray water at the ignition point at a fixed angle. The use of the spiral nozzle expands the coverage range of the water spray, and the ignition point within a certain range can be sprayed with water to extinguish the fire. Using the rotating water gun of this scheme, not only can the angle be adjusted to more accurately aim at the ignition point, but also the ignition point within the range can be extinguished, which greatly improves the fire extinguishing efficiency.

[0014] Furthermore, the angle fixing device includes a first fixing rod and a second fixing rod, one end of the first fixing rod is rotatably connected to the first tube body, one end of the second fixing rod is rotatably connected to the second tube body, and the other end of the first fixing rod and the other end of the second fixing rod are connected by bolts. By locking the first fixing rod and the second fixing rod with bolts, the relative angle between the first tube body and the second tube body can be fixed, which is not only simple in structure, but also convenient to adjust and easy to operate.

[0015] Furthermore, a damping mechanism is provided between the other end of the first fixing rod and the other end of the second fixing rod. The damping mechanism can prevent the second tube body from suddenly changing its angle relative to the first tube body after the bolt is loosened, and a certain damping can be provided when adjusting the angle of the second tube body and the first tube body, so that the angle can be adjusted more accurately.

[0016] Furthermore, the damping mechanism includes at least one friction plate, which is arranged between the first fixing rod and the second fixing rod, and the bolt passes through the friction plate. The friction plate increases the friction force between the two fixing rods, has a simple structure and low cost, and the damping of the friction plate is controlled by the extrusion force of the bolt when adjusting.

[0017] Furthermore, the damping mechanism comprises a first damping plate and a second damping plate whose end surfaces are close to each other, and the first damping plate and the second damping plate are both provided with teeth meshing with each other. Another damping mechanism, the damping plates are close to each other and meshed with teeth, so that when the two damping plates are close to each other, it is not easy to rotate relative to each other, which has the function of locking the angle and can better fix the angle between the two fixing rods.

[0018] Further, the bracket includes a hoop and a support leg, the hoop is sleeved on the second tube body, and the support leg is rotatably connected to the hoop. The hoop and the support leg provide a fulcrum for the second tube body, and the extension tube can be manually controlled to swing in a vertical plane when necessary.

[0019] Furthermore, the hoop is located between the center of gravity of the extension tube and the spiral sprinkler. When placed normally, the spiral sprinkler is kept in an upturned position to prevent the spiral sprinkler from being damaged by touching the ground. BRIEF DESCRIPTION OF THE DRAWINGS

The extension tube is divided into the first tube body 21 and the second tube body 22, and the first tube body 21 and the second tube body 22 are hinged, so that the first tube body 21 can swing within a certain range relative to the second tube body 22, so that the water sprayed from the spiral nozzle 40 has a larger adjustment angle, and the angle fixing device 30 can be used to fix the relative position of the first tube body 21 and the second tube body 22, and spray water at the ignition point at a fixed angle, and the spiral nozzle 40 is used to expand the coverage of the water spray, and the ignition point within a certain range can be sprayed with water to extinguish the fire.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] See also Figures 1 to 3 This is an embodiment of the utility model of a rotating water gun for fire fighting, which includes an extension pipe and a bracket 10 for supporting the extension pipe. The extension pipe is mainly used to extend into the interior of a building for fire extinguishing. A standard water hose interface 50 is provided at the tail end of the extension pipe for docking with a fire hose. A nozzle is provided at the head of the extension pipe for spraying water toward the fire point. The bracket 10 is used to support the extension pipe so that its head is lifted off the ground to obtain a certain height to better play a fire extinguishing role.

[0036] In this embodiment, the extension tube includes a hinged first tube body 21 and a second tube body 22, that is, the head of the second tube body 22 and the tail of the first tube body 21 are hinged by a connecting piece such as a ball head or a hinge, so that the first tube body 21 can rotate relative to the second tube body 22 within a certain angle range to expand the water spray range. Due to the hinged relationship between the first tube body 21 and the second tube body 22, the first tube body 21 and the second tube body 22 cannot be connected inside, so a connecting pipe 23 is provided between the tail of the first tube body 21 and the head of the second tube body 22, so that the water in the second tube body 22 can flow into the first tube body 21. The corresponding water hose interface 50 is located at the tail of the second tube body 22, and the head of the first tube body 21 is provided with a spiral spray head 40, which can make the water produce a spiral spray to cover a larger range. The bracket 10 is connected to the second tube body 22, and the size of the second tube body 22 is larger than the first tube body 21. The bracket 10 is connected to the second tube body 22 to make the entire water gun more stable. In order to fix the relative angle between the first tube body 21 and the second tube body 22 after the first tube body 21 rotates relative to the second tube body 22 , an angle fixing device 30 is further provided between the first tube body 21 and the second tube body 22 .

[0037] Furthermore, the angle fixing device 30 includes a first fixing rod 31 and a second fixing rod 32, one end of the first fixing rod 31 is rotatably connected to the first tube body 21, one end of the second fixing rod 32 is rotatably connected to the second tube body 22, the other end of the first fixing tube and the other end of the second fixing tube are connected by a bolt 33, and the angle between the first fixing rod 31 and the second fixing rod 32 is locked by the bolt 33 and the nut, so as to achieve the purpose of locking the angle of the first tube body 21 and the second tube body 22. This method is simple to operate, does not require a special learning process for operators, and has a reliable connection.

[0038] Furthermore, a damping mechanism is provided between the other end of the first fixing rod 31 and the other end of the second fixing rod 32. Through the damping mechanism, after the bolt 33 is loosened, the angles of the first tube body 21 and the second tube body 22 will not change rapidly, thereby avoiding the danger and impact on the hinge caused by the sudden downward rotation of the first tube body 21. The damping mechanism can also provide sufficient time to fix the angle of the first tube body 21 after adjusting its angle.

[0039] The specific structure of the damping mechanism includes but is not limited to the following specific structural forms:

[0040] like Figure 2 As shown, a structural form of the damping mechanism includes at least one friction plate 34, which is located between the first fixing rod 31 and the second fixing rod 32, and the bolt 33 passes through the friction plate 34. The friction force of the friction plate 34 is controlled by the tightness of the bolt 33. After the bolt 33 is tightened, the friction force between the two fixing rods can also be increased to avoid mutual rotation. As the bolt 33 is loosened more, the friction force generated by the friction plate 34 is smaller, and it is easier to adjust the angle between the two tubes.

[0041] like Figure 3 As mentioned above, another structural form of the damping mechanism includes a first damping plate 35 and a second damping plate 36 whose end surfaces are close to each other. The first damping plate 35 can be fixedly connected to the first fixing rod 31, or can be squeezed when the bolt 33 is tightened, so that the friction between the first damping plate 35 and the first fixing rod 31 increases to fix the relative position of the two. Similarly, the second damping plate 36 and the second fixing rod 32 can also be fixedly connected or kept in close contact. The first damping plate 35 and the second damping plate 36 are both provided with teeth on the end surfaces that are close to each other. Through the mutual meshing of the teeth, when the bolt 33 is tightened to a certain extent, the teeth on the two damping plates can mesh with each other, thereby locking the relative angle between the two fixing rods, that is, the angle between the first fixing rod 31 and the second fixing rod 32 can be locked in advance without the bolt 33 being fully tightened.

[0042] On the basis of the above embodiment, the bracket 10 includes a clamp 11 and a support leg 12. The clamp 11 is sleeved on the second tube body 22. The support leg 12 is rotatably connected to the clamp 11. The support leg 12 and the clamp 11 can be locked to fix the position of the second tube body 22, or the support leg 12 and the clamp 11 can be unlocked to facilitate the adjustment of the angle of the second tube body 22.

[0043] Furthermore, the clamp 11 is located between the center of gravity of the extension tube and the spiral nozzle 40, so that the spiral nozzle 40 can be kept lifted off the ground at all times, thereby preventing the spiral nozzle 40 from hitting the ground and being damaged.

[0044] When fire extinguishing is needed, connect the fire hose to the hose interface 50 at the tail end of the second tube body 22, adjust the angle of the first tube body 21 and the second tube body 22 by observing the position angle of the fire point in the fire scene, and then lock the relative position of the first fixing rod 31 and the second fixing rod 32 in the angle fixing device 30 by tightening the bolt 33, thereby locking the relative angle of the first tube body 21 and the second tube body 22, and then push the device toward the fire scene and supply water to the hose, so that the rotating nozzle enters the fire scene and sprays spiral water flow at the fire point. In addition to more accurately extinguishing the fire at the fire point, it can also cover a certain area for fire extinguishing, greatly improving the fire extinguishing efficiency.

[0045] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
