[0002] Fire monitors, as long-range fire extinguishing devices using water as a medium, are widely used in petrochemical enterprises, tank farms, aircraft hangars, warehouses, ports, and docks. In actual operation, the fire-fighting environment in high-rise buildings is complex and variable. The nozzles and key components are easily covered by dust, smoke, and other pollutants at the fire scene, leading to obstructed rotation and reduced spraying function. In existing technology, the high-efficiency fire monitor disclosed in patent number CN217961072U, although using a shield to protect the barrel and body, employs a fixed connection method and lacks a convenient disassembly structure. When the shield is damaged or aged during long-term use, it is impossible to quickly replace the parts, resulting in loss of protective function and affecting the normal operation and fire-fighting efficiency of the monitor. Especially in high-rise operation scenarios, equipment maintenance is difficult, and the non-replaceability of protective components further exacerbates equipment reliability issues, posing additional risks to on-site fire-fighting operations.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

A fixing rod is provided on the top of the locking block, and a protective cover is provided on the top of the two fixing rods.

[0006] Furthermore, this application also proposes that the connection points between the two sides of the bottom of the protective cover and the fixing rod are fixedly connected by connecting blocks, and the two fixing rods are arranged symmetrically about the protective cover.

[0007] Furthermore, this application also proposes that the two ends of the return spring are fixedly connected to the top block and the bearing hole by welding, and the diameter of the top block is smaller than the diameter of the bearing hole.

[0008] Furthermore, this application also proposes that the top of the top block is semi-circular, and that the top of the top block can exert upward pressure on the locking block by the pressure of the reset spring.

[0009] Furthermore, this application also proposes that a handle be provided on the other side of the connecting pipe, and that the surface of the handle be covered with an anti-slip sleeve.

[0014] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0015] Please see Figure 1-4This application proposes a high-rise fire-extinguishing water cannon device, including a water inlet pipe 1. The top of the water inlet pipe 1 is connected to two branch pipes 3. A connecting pipe 7 is rotatably connected to one side of the two branch pipes 3. A nozzle 4 is connected to one side of the connecting pipe 7. A protective component 5 is provided on the top of the connecting pipe 7. The protective component 5 includes two fixing plates 501, and the bottom of the two fixing plates 501 is fixedly connected to the connecting pipe 7. A slot 506 is opened on the top of the fixing plate 501. A locking block 505 is locked in the inner cavity of the slot 506. A bearing hole 507 is opened on both sides of the inner cavity of the fixing plate 501. A top block 508 is movably arranged in the inner cavity of the bearing hole 507. A return spring 509 is provided at the connection between the bottom of the top block 508 and the bearing hole 507. The top of the top block 508 is in close contact with the locking block 505. A fixing rod 504 is provided on the top of the locking block 505. A protective cover 502 is provided on the top of the two fixing rods 504.

[0016] The protective component 5 can be understood as a structural design to prevent dust accumulation and facilitate replacement. Specifically, the fixing plate 501 can be fixedly connected to the connecting pipe 7 by bolts or welding, thereby ensuring the stability of the overall structure. The slot 506 can be designed in a rectangular, trapezoidal, or other adaptable shape to meet the installation requirements of different locking blocks 505. The material of the locking block 505 can be metal or high-strength plastic, and its wear resistance can be improved through surface treatment. The shape and size of the bearing hole 507 can be adjusted according to the movement trajectory of the top block 508, for example, by using a cylindrical or square hole to facilitate the flexible movement of the top block 508 inside. The return spring 509 can be replaced with an elastic rubber part or other components with a rebound function to provide continuous pressure support. In addition to being semi-circular, the top shape of the top block 508 can also be designed as a flat surface or other adaptable shape to achieve effective contact with the locking block 505. The connection between the fixing rod 504 and the protective cover 502 can be a threaded connection or a plug-in connection, thereby improving the convenience of disassembly and installation.

[0017] Furthermore, the design of the protective cover 502 can be achieved through a modular approach. For example, the protective cover 502 can be divided into multiple independent units, each of which is individually connected to the fixing rod 504, so that only the corresponding unit needs to be replaced in case of partial damage. The number and distribution of the fixing rods 504 can be adjusted according to the size of the protective cover 502. For example, the number of fixing rods 504 can be increased to improve the support strength, or the number of fixing rods 504 can be reduced to simplify the structure.

[0018] The innovation of this application lies in the design of a detachable protective component 5, which solves the problem of the protective cover 502 being unable to be replaced in a timely manner when damaged. The coordinated structure of the slot 506, locking block 505, top block 508, and return spring 509 in the protective component 5 allows the protective cover 502 to be quickly disassembled and replaced when needed, avoiding the maintenance difficulties caused by the non-removable nature of traditional shields. At the same time, this design ensures the stability of the protective cover 502 under normal operating conditions, thereby effectively preventing dust accumulation from affecting the water cannon device.

[0019] The working principle of this embodiment is as follows: The inlet pipe 1 provides a stable water source input, and the two branch pipes 3 connected at its top form a symmetrical water flow channel, providing a structural basis for the operation of the subsequent protective component 5. The connecting pipe 7 is rotatably connected to the corresponding side of the two branch pipes 3, allowing the direction of the nozzle 4 to be flexibly adjusted, while reserving rotation space for the installation of the protective component 5. The nozzle 4 connected to one side of the connecting pipe 7 realizes the directional spraying of fire extinguishing water, while the protective component 5 set at the top of the connecting pipe 7 directly protects against dust accumulation. Among them, the bottom of the two fixing plates 501 in the protective component 5 is fixedly connected to the connecting pipe 7 to ensure the stability of the overall structure. The slot 506 opened at the top of the fixing plate 501 provides a precise locking position for the locking block 505, so that the protective cover 502 can be quickly positioned during installation. The locking block 505 locked in the inner cavity of the slot 506 achieves temporary fixation through cooperation with the slot 506, which is convenient for manual disassembly. Furthermore, the bearing holes 507 opened on both sides of the inner cavity of the fixing plate 501 accommodate the movement of the top block 508, providing internal space for disassembly operations. The top block 508, movably mounted within the bearing hole 507, can move up and down under the action of the return spring 509. The return spring 509, located at its bottom where it connects to the bearing hole 507, provides continuous elastic force, allowing the top block 508 to automatically reset. Specifically, the top of the top block 508 is in close contact with the locking block 505. The pressure of the return spring 509 pushes the locking block 505 upwards, thus locking it in the slot 506 under normal conditions. A fixing rod 504 at the top of the locking block 505 connects to the protective cover 502. When the top block 508 moves downwards, it causes the locking block 505 to disengage from the slot 506, enabling the rapid release of the protective cover 502. Thus, the protective cover 502 at the top of the two fixing rods 504 covers the nozzle area 4, preventing dust intrusion. Furthermore, due to the linkage design between the fixing rods 504 and the locking block 505, the top block 508 can be easily removed and replaced when damaged, avoiding the maintenance difficulties caused by the inability to disassemble traditional baffles. As a preferred embodiment, this technical solution effectively solves the problem that the protective cover 502 is easily damaged and cannot be replaced in a dusty environment by designing a detachable protective component 5, ensuring that the water cannon device can continue to work normally at the fire scene without being obstructed.

[0020] This application further proposes that the connection points between the two sides of the bottom of the protective cover 502 and the fixing rod 504 are fixedly connected by the connecting block 503, and the two fixing rods 504 are arranged symmetrically about the protective cover 502.

[0021] Specifically, the connecting block 503 is a structural component used to indirectly connect the protective cover 502 and the fixing rod 504. It can be made of metal plate, high-strength plastic, or composite material, with the aim of providing a detachable connection method to facilitate the replacement and maintenance of the protective cover 502. In practical applications, the centrally symmetrical arrangement means that the two fixing rods 504 are evenly distributed on the protective cover 502 with its center point as the axis of symmetry. This design ensures that the protective cover 502 is subjected to balanced forces during installation and operation, avoiding loosening or deformation caused by stress concentration on one side.

[0022] In detail, the protective cover 502 is indirectly connected to the fixing rod 504 via the connecting block 503. This design avoids the rigid constraints of direct fixing. When the protective cover 502 needs to be replaced, only the connecting block 503 needs to be removed to complete the operation, without adjusting the fixing rod 504 or the locking block 505, significantly improving maintenance efficiency. Meanwhile, the two fixing rods 504 are centrally symmetrical about the protective cover 502, ensuring not only the stability of the protective cover 502 during installation but also providing a balanced leverage point for its disassembly, further enhancing the ease of operation. This solution, by optimizing the connection between the protective cover 502 and the fixing rod 504, solves the problem of timely replacement of the protective cover 502 after damage. Together with the inlet pipe 1, branch pipe 3, connecting pipe 7, and nozzle 4, it constitutes a complete high-rise fire-fighting water cannon device, ensuring the reliability and efficiency of the equipment in complex environments.

[0023] This application further proposes that the two ends of the return spring 509 are fixedly connected to the top block 508 and the bearing hole 507 by welding, and the diameter of the top block 508 is smaller than the diameter of the bearing hole 507.

[0024] Specifically, the return spring 509 is an elastic element made of stainless steel to ensure good fatigue resistance during long-term use. The welded fixed connection refers to permanently connecting both ends of the return spring 509 to the top block 508 and the bearing hole 507 respectively by melting metal at high temperature. This connection method effectively avoids loosening problems caused by vibration or water pressure impact. The design of the top block 508 having a smaller diameter than the bearing hole 507 allows the top block 508 to slide freely within the bearing hole 507, while preventing jamming due to excessive size.

[0025] In detail, the above technical solution, through a dual design of welding fixation and dimensional adaptation, ensures the stability and maintainability of the return spring 509 during dynamic use. The two ends of the return spring 509 are fixed to the top block 508 and the bearing hole 507 by welding. Utilizing the high strength of welding, the defects of traditional elastic snap-fit ​​or friction connections that are prone to loosening under long-term vibration are avoided, thus ensuring that the return spring 509 can continuously and stably transmit the return force to the top block 508. The flexible sliding design of the top block 508 within the bearing hole 507 ensures both the accuracy of the top block 508's movement when constrained by the spring and the smooth return of the top block 508 when the protective cover 502 is disassembled. This design not only enhances the durability of the spring system but also optimizes the response efficiency of the top block 508's movement, keeping the protective cover 502 stable during firefighting operations and allowing for efficient separation during maintenance, significantly improving the overall practicality of the device. Furthermore, the above design, combined with other structures of the protective component 5, further enhances the reliability and ease of operation of the protective cover 502, and solves the problem of the protective cover 502 being not securely fixed or difficult to disassemble due to the unreliable connection of the return spring 509.

[0026] This application further proposes that the top of the top block 508 is semi-circular, and the top of the top block 508 can exert upward pressure on the locking block 505 by the pressure of the reset spring 509.

[0027] Specifically, the top block 508 is a structural component used to apply pressure to push the locking block 505 out of the locking slot 506. It can be made of metal or high-strength plastic, and its semi-circular top design reduces frictional resistance when in contact with the locking block 505. The return spring 509 is an elastic element that provides a continuous upward thrust to ensure that the top block 508 remains in close contact with the locking block 505, thereby achieving a rapid release function. The purpose of this design is to optimize the ease of operation during the disassembly of the protective cover 502 and improve the overall structural reliability.

[0028] In detail, in the above solution, the semi-circular top design of the top block 508, combined with the stable pressure provided by the return spring 509, makes the force on the locking block 505 more even and concentrated when it disengages from the slot 506. Because the top shape of the top block 508 is optimized, it avoids the jamming phenomenon that may be caused by planar contact. Therefore, in actual use, the locking block 505 can move smoothly and quickly disengage from the slot 506. At the same time, the return spring 509 not only ensures the continuous pressure of the top block 508 on the locking block 505, but also enhances the stability of the entire protective assembly 5. Based on this, the connecting pipe 7, the fixing plate 501, and the protective cover 502 together constitute a complete protective system. The various parts cooperate with each other, effectively solving the problem of difficulty in releasing the locking block 505 caused by the unoptimized shape of the top block 508, thereby enabling rapid replacement and maintenance of the protective cover 502.

[0029] Through the above technical solutions, the operational efficiency of the protective component 5 is significantly improved. In particular, in emergency situations, the protective cover 502 can be quickly disassembled and replaced, ensuring the normal operation of the high-rise fire-fighting water cannon device.

[0030] This application further proposes that a handle 6 is provided on the other side of the connecting pipe 7, and the surface of the handle 6 is covered with an anti-slip sleeve.

[0031] Specifically, the grip 6 refers to an operating component for the operator to grasp and apply torque. It can be cylindrical, elliptical, or other ergonomically shaped. In practical applications, the grip 6's position design must avoid interference with the nozzle 4 and other components, while providing a lever fulcrum for easy force application, thereby improving operational convenience. The anti-slip sleeve can be understood as a protective layer used to enhance friction. Its material can be rubber, silicone, or textured composite materials, aiming to significantly improve grip stability in wet and slippery environments and prevent operational errors caused by water flow.

[0032] In detail, by adding a handle 6 to the other side of the connecting pipe 7, the problem of unstable grip caused by smooth or slippery surfaces during operation can be effectively solved. The design position of the handle 6 fully considers the rotating connection structure of the connecting pipe 7, ensuring that it will not obstruct the directional adjustment of the nozzle 4, while providing the operator with a force-saving point of application, making the directional control of the nozzle 4 more precise. In addition, the introduction of the anti-slip sleeve is based on the actual needs of the fire extinguishing site. Its surface texture or material properties can maintain a high coefficient of friction even under wet conditions, thereby preventing the hand from slipping. The above solutions not only improve the safety of operation, but also optimize the efficiency and accuracy of the directional adjustment of the nozzle 4, reflecting the practicality and reliability of the overall design.

[0033] This application further proposes that the bottom of the water inlet pipe 1 is provided with a mounting flange 2, and the inner cavity of the mounting flange 2 is provided with a mounting hole.

[0034] Specifically, mounting flange 2 refers to a ring-shaped structural component, which can be made of metal or high-strength composite materials, and its purpose is to provide a stable mounting base for the device. Mounting holes are through holes formed inside the cavity of mounting flange 2, which can be machined using drilling processes, and their purpose is to cooperate with fasteners to achieve a secure connection between the device and the supporting surface.

[0035] In detail, in the high-rise fire-fighting water cannon device, the inlet pipe 1 serves as the load-bearing foundation and water inlet of the entire device. The mounting flange 2 is located at its bottom, allowing the rigid structure of the inlet pipe 1 to directly distribute installation stress. This design avoids the introduction of additional supports, simplifying the installation process and enhancing the overall structural stability. The annular load-bearing characteristics of the mounting flange 2 allow fasteners to apply pressure evenly through the mounting holes, ensuring a tight fit between the flange and the mounting surface. This structural design is particularly suitable for high-pressure water flow operation in high-rise environments, effectively preventing device displacement under external environmental interference, thereby ensuring the reliability and operational safety of the fire-fighting process.

[0036] Furthermore, the mounting flange 2, together with other components of the aforementioned high-rise fire-fighting water cannon device, forms a complete fixing system. By integrating the mounting flange 2 at the bottom of the water inlet pipe 1 and designing mounting holes, the problem of unstable installation of the device is effectively solved, ensuring that the device will not shake or fall off due to wind or water pressure during operation, significantly improving the fire-fighting effect and operational safety.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
