Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and in particular relates to a high-pressure water cannon for fire protection. Background Technology

[0002] Existing fire-fighting high-pressure water cannon technology is mainly divided into two categories: continuous spray type and water bullet launch type. Continuous spray type water cannons rely on a high-pressure water source to generate a stable water jet or mist, which is then sprayed over a long distance via a fixed mounting bracket or vehicle-mounted platform to suppress fire sources or create a protective water curtain. Water bullet launch type technology uses compressed air or other power to propel units containing extinguishing agents to the target area, achieving the effect of penetrating obstacles or precisely covering specific fire points. Both of these mainstream technologies require the water cannon body to be rigidly mounted on a specific mounting bracket, fire truck, or fixed base to obtain the necessary support stability.

[0003] However, the aforementioned technologies share a common critical flaw: during high-pressure jetting or projectile launch, water cannons inevitably generate significant recoil and mechanical vibration. This vibrational energy is directly transmitted to the supporting gun mount structure, causing continuous shaking of the entire launch platform. This shaking interferes with the water cannon's aiming baseline, severely impacting the accuracy and stability of the landing point for both water jet spraying that requires continuous tracking of the fire and water projectile launches that demand precise hits, thus reducing firefighting efficiency. This problem is particularly pronounced in complex fire scene environments requiring high-precision operation. Utility Model Content

[0004] The purpose of this utility model is to provide a high-pressure water cannon for fire fighting, which aims to solve the technical problem that the accuracy and stability of the water jet or water bullet landing point of the fire cannon are seriously affected by the vibration generated during use.

[0005] To achieve the above objectives, this utility model provides a high-pressure water cannon for firefighting, comprising a fixed base, a connecting mechanism, and a launcher. The connecting mechanism is disposed on the fixed base; the launcher is disposed on the connecting mechanism; the connecting mechanism includes a buffer, a shock-absorbing ring, and a connecting ring. The connecting ring is disposed on the fixed base, the shock-absorbing ring is disposed on the side wall of the launcher, the connecting ring and the shock-absorbing ring are connected by the buffer, the launcher is located inside the shock-absorbing ring, and the shock-absorbing ring is located inside the connecting ring.

[0007] Optionally, the buffer is made of an elastic material, and the shock-absorbing ring can be slightly offset relative to the connecting ring through the buffer.

[0008] Optionally, a gap is provided between the shock-absorbing ring and the connecting ring, and the outer ring of the shock-absorbing ring and the inner ring of the connecting ring are respectively provided with a first connecting block and a second connecting block, and the two ends of the buffer are respectively provided on the first connecting block and the second connecting block.

[0009] Optionally, the ends of both the first connecting block and the second connecting block protrude and extend in the direction of the gap. A first groove is formed between the end of the first connecting block and the outer sidewall of the shock-absorbing ring, and a second groove is formed between the end of the second connecting block and the inner sidewall of the connecting ring. The buffer is an elastic rubber ring, and both ends of the buffer are sleeved on the first groove and the second groove.

[0010] Optionally, the buffer is an annular air tube, and the first connecting block and the second connecting block are respectively provided with a first mounting groove and a second mounting groove. The two ends of the buffer are respectively inserted into the first mounting groove and the second mounting groove, and the middle part of the buffer is located in the gap. The buffer is made of high-strength rubber.

[0011] Optionally, the buffer includes an elastic airbag and a third connecting block. There are two sets of the third connecting blocks. The two sets of the third connecting blocks are fixedly disposed at both ends of the elastic airbag, and the two sets of the third connecting blocks are respectively connected to the first connecting block and the second connecting block.

[0014] Optionally, the connecting frame is a tripod, and both the rotating seat and the fixed base are arranged in a disc-shaped structure. The three supporting legs of the connecting frame are evenly spaced along the circumferential edge of the rotating seat.

[0015] The above-mentioned technical solutions of one or more of the high-pressure water cannons for firefighting provided in this utility model embodiment have at least one of the following technical effects: By setting a connecting mechanism including a buffer, a shock-absorbing ring, and a connecting ring between the fixed base and the launcher, effective isolation of recoil and mechanical vibration is achieved. When the launcher sprays, the vibration generated is transmitted to the shock-absorbing ring, and the buffer absorbs and disperses the vibration energy, blocking the direct transmission of vibration to the fixed base. This design allows the launcher to maintain a stable posture under the protection of the shock-absorbing ring, while the rigid connection between the connecting ring and the base remains undisturbed. The physical vibration isolation mechanism suppresses the shaking of the cannon frame, ensuring that the trajectory of the water jet or water bullet is not disturbed by the vibration of the supporting structure, greatly improving the stability of continuous aiming or precise projection at the fire source, thereby enhancing firefighting efficiency and operational reliability in complex fire environments.

[0025] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-7 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-7As shown, a high-pressure water cannon for firefighting is provided, including a fixed base 100, a connecting mechanism 200, and a launcher 300. The connecting mechanism 200 is disposed on the fixed base 100; the launcher 300 is disposed on the connecting mechanism 200; the connecting mechanism 200 includes a buffer 210, a shock-absorbing ring 220, and a connecting ring 230. The connecting ring 230 is disposed on the fixed base 100, the shock-absorbing ring 220 is disposed on the side wall of the launcher 300, the connecting ring 230 and the shock-absorbing ring 220 are connected by the buffer 210, the launcher 300 is located inside the shock-absorbing ring 220, and the shock-absorbing ring 220 is located inside the connecting ring 230.

[0030] By setting a connecting mechanism 200, which includes a buffer 210, a shock-absorbing ring 220, and a connecting ring 230, between the fixed base 100 and the launcher 300, effective isolation of recoil and mechanical vibration is achieved. When the launcher 300 sprays water, the vibration generated is transmitted to the shock-absorbing ring 220, and the buffer 210 absorbs and disperses the vibration energy, blocking the direct transmission of vibration to the fixed base 100. This design allows the launcher 300 to maintain a stable posture under the protection of the shock-absorbing ring 220, while the rigid connection between the connecting ring 230 and the base remains undisturbed. The physical vibration isolation mechanism suppresses the vibration of the launcher mount, ensuring that the trajectory of the water jet or water bullet is not affected by the vibration of the supporting structure, greatly improving the stability of continuous aiming or precise projection at the fire source, thereby enhancing fire extinguishing efficiency and operational reliability in complex fire environments.

[0031] like Figures 1-7 As shown, in another embodiment of this utility model, the number of buffer members 210 is multiple sets, and the multiple sets of buffer members 210 are evenly distributed along the circumferential edge of the launcher 300. The multiple sets of buffer members 210 are evenly arranged around the circumference of the launcher 300 to form a ring-shaped multi-point distributed damping structure. When vibration is transmitted from the launcher 300 to the shock-absorbing ring 220, the evenly distributed buffer members 210 can simultaneously and evenly absorb the impact energy from all directions. This design effectively overcomes the stress concentration and uneven energy absorption problems that may be caused by a single point or a small number of buffer members 210, so that the vibration energy is evenly distributed and absorbed in the circumferential direction, significantly improving the stability and reliability of the overall buffer system, further suppressing the overall or local abnormal shaking of the gun mount caused by uneven vibration distribution, and ensuring the linearity and stability of the firing trajectory.

[0032] like Figures 1-7As shown, in another embodiment of this invention, the buffer 210 is made of an elastic material, and the anti-vibration ring 220 can be slightly offset relative to the connecting ring 230 via the buffer 210. The buffer 210, made of elastic material, undergoes recoverable deformation under stress, allowing the anti-vibration ring 220 (along with the launcher 300) to produce a small, non-rigid displacement relative to the connecting ring 230. This elastic offset mechanism provides a crucial flexible connection, enabling the intense vibration energy generated by the launcher 300 during high-pressure injection to be effectively absorbed and dissipated by the elastic deformation of the buffer 210. This directly solves the problem in the prior art where rigid connections amplify vibration transmission, causing overall gun mount vibration, and ensures the relative stability of the launcher 300's working posture.

[0033] like Figures 1-7 As shown, in another embodiment of this utility model, a gap is provided between the shock-absorbing ring 220 and the connecting ring 230. The outer ring of the shock-absorbing ring 220 and the inner ring of the connecting ring 230 are respectively provided with a first connecting block 240 and a second connecting block 250. The two ends of the buffer member 210 are respectively disposed on the first connecting block 240 and the second connecting block 250. A physical gap is left between the shock-absorbing ring 220 and the connecting ring 230, and both are connected to the two ends of the buffer member 210 through the connecting blocks on their respective outer and inner rings. The buffer member 210 spans the gap, connecting both sides. The existence of the gap provides necessary space for the deformation of the buffer member 210 and the slight displacement of the shock-absorbing ring 220, avoiding rigid collisions. Fixing the buffer member 210 with the connecting blocks ensures that the effective force transmission path is concentrated on the buffer member 210 itself. This design concentrates and optimizes the absorption path of vibration energy, effectively isolating the possibility of vibration being directly transmitted to the base through structural gaps, and significantly reducing the associated vibration of the base and the gun mount.

[0034] like Figures 1-7As shown, in another embodiment of this utility model, the ends of the first connecting block 240 and the second connecting block 250 both protrude and extend in the direction of the gap. A first groove 260 is formed between the end of the first connecting block 240 and the outer sidewall of the shock-absorbing ring 220, and a second groove 270 is formed between the end of the second connecting block 250 and the inner sidewall of the connecting ring 230. The buffer member 210 is an elastic rubber ring, and both ends of the buffer member 210 are sleeved on the first groove 260 and the second groove 270. The protruding ends of the connecting blocks form a groove structure, and the two ends of the elastic rubber ring-shaped buffer member 210 are directly sleeved in these grooves. The groove structure provides a simple and reliable hanging method, making the elastic rubber ring easy to install and position. The sleeve method allows the rubber ring to undergo tensile deformation mainly when subjected to force, efficiently absorbing vibration energy. This structural design cleverly utilizes the elasticity of the rubber ring, while solving the problem of easy loosening or failure of the connection between the buffer member 210 and the connecting block under long-term vibration, enhancing the durability and connection reliability of the buffer mechanism in a continuous vibration environment.

[0035] like Figures 1-7 As shown, in another embodiment of this utility model, the buffer 210 is an annular air tube. The first connecting block 240 and the second connecting block 250 are respectively provided with a first mounting groove and a second mounting groove. The two ends of the buffer 210 are respectively inserted into the first mounting groove and the second mounting groove, and the middle part of the buffer 210 is located in the gap. The buffer 210 is made of high-strength rubber. The two ends of the annular air tube-shaped buffer 210 are inserted into the mounting grooves on the connecting blocks for fixation, and the middle suspended part is located in the gap between the shock-absorbing ring 220 and the connecting ring 230. It is made of high-strength rubber. When the annular air tube structure is compressed or stretched, its internal cavity can provide additional deformation space and gas damping effect, combined with the elasticity of rubber, to form a composite energy absorption mechanism. The insertion installation provides a firm connection. This design greatly improves the energy absorption efficiency and fatigue resistance of a single buffer element, and can more effectively cope with the high-intensity, high-frequency vibration impact generated when the high-pressure water cannon is working, thereby more reliably preventing the vibration energy from being transmitted to the gun mount and causing shaking.

[0036] like Figures 1-7As shown, in another embodiment of this utility model, the buffer 210 includes an elastic airbag 211 and a third connecting block 212. There are two sets of third connecting blocks 212, each fixedly disposed at both ends of the elastic airbag 211. Each set of third connecting blocks 212 is connected to the first connecting block 240 and the second connecting block 250, respectively. The buffer 210 is composed of a central elastic airbag 211 and third connecting blocks 212 fixed at both ends. The third connecting blocks 212 are connected to the first connecting block 240 on the shock-absorbing ring 220 and the second connecting block 250 on the connecting ring 230, respectively. The airbag structure has excellent compression deformation capacity and damping characteristics, and can efficiently absorb and dissipate vibration energy. The connection via the third connecting blocks 212 facilitates modular installation, maintenance, or replacement of the airbag. This design provides a highly buffered and easy-to-maintain solution, which is particularly suitable for applications requiring the ability to withstand extremely strong instantaneous impacts. It effectively isolates the transmission of severe vibrations to the fixed base 100, minimizing the impact of gun mount vibrations on aiming accuracy.

[0037] like Figures 1-7 As shown, in another embodiment of this utility model, an adjustment assembly 110 is provided on the fixed base 100. The adjustment assembly 110 includes a horizontal adjustment unit 111 and a vertical adjustment unit 112. The horizontal adjustment unit 111 is disposed on the fixed base 100, and the vertical adjustment unit 112 is disposed on the horizontal adjustment unit 111. The connecting ring 230 is disposed at the output end of the vertical adjustment unit 112. The adjustment assembly 110, which includes a horizontally rotatable unit and a vertically adjustable unit, is added to the fixed base 100. The connecting ring 230 (i.e., the entire connecting mechanism 200) is installed at the output end of the vertical adjustment unit 112. This adjustment assembly 110 allows the operator to precisely adjust the horizontal pointing angle and pitch angle of the water cannon launcher 300 while keeping the base fixed. During and after adjustment, the buffering function of the connecting mechanism 200 remains effective, ensuring that the vibration generated by the launcher 300 can be effectively absorbed and isolated regardless of its pointing direction, and the stability of the launcher is not affected by the aiming operation. This solves the problem in existing technologies where adjusting the muzzle direction may affect the stability of the base or result in poor buffering after adjustment, achieving a balance between aiming flexibility and firing stability. The vertical adjustment unit 112 is a rotational pivot.

[0038] like Figures 1-7As shown, in another embodiment of this utility model, the horizontal adjustment unit 111 includes a rotating base 113 and a connecting frame 114. The rotating base 113 is rotatably connected to the fixed base 100. One end of the connecting frame 114 is fixedly connected to the rotating base 113, and the other end of the connecting frame 114 extends upward away from the rotating base 113. The vertical adjustment unit 112 is fixedly disposed at the top of the connecting frame 114. Horizontal adjustment is achieved through a rotatable base fixed to the base. One end of the connecting frame 114 is fixed to the rotating base 113, and the other end extends upward to support the vertical adjustment unit 112. The entire buffer mechanism and the launcher 300 are supported by the vertical adjustment unit 112. The rotating base 113 provides a stable horizontal rotation foundation, and the connecting frame 114 raises the vertical adjustment unit 112 to a suitable height. This structural design decouples horizontal rotation adjustment from vertical pitch adjustment, making aiming operation smoother and more stable. Meanwhile, the connecting frame 114 effectively transfers the weight and working load of the buffer mechanism and the transmitter 300 to the rotating seat 113 and the base, ensuring the structural strength and stability of the entire adjustment assembly 110 under load and vibration impact, and avoiding the introduction of new vibration sources due to insufficient rigidity or deformation of the adjustment mechanism.

[0039] like Figures 1-7 As shown, in another embodiment of this utility model, the connecting frame 114 is a triangular frame, and both the rotating seat 113 and the fixed base 100 are arranged in a disc-shaped structure. The three supporting legs of the connecting frame 114 are evenly distributed along the circumferential edge of the rotating seat 113. The connecting frame 114 adopts a triangular frame structure with three supporting legs, and the three legs are evenly distributed on the edge of the disc-shaped rotating seat 113. The rotating seat 113 and the fixed base 100 are also disc-shaped. The triangular frame structure has excellent mechanical stability and torsional resistance, and the evenly distributed supporting legs ensure that the load and vibration can be evenly transmitted to the rotating seat 113. The disc-shaped rotating seat 113 and the fixed base 100 provide symmetrical bearing surfaces and rotational support. This design greatly enhances the rigidity and stability of the entire adjustment assembly 110 and support structure. Even when the powerful jet from the launcher 300 generates significant recoil and vibration, it can effectively resist deformation and shaking, fundamentally preventing muzzle tremors caused by deformation or instability of the support structure itself, and ensuring the long-term maintenance of aiming accuracy.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
