Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire monitor technology, specifically a fire monitor jet shaping and acceleration device. Background Technology
[0002] Fire monitors are widely used in firefighting operations in various large venues, their main function being to extinguish fires using powerful water jets. However, in existing technology, most fire monitors are relatively simple in design, typically controlling water flow and jet pattern manually or mechanically, with limited control over water velocity and pattern. The spray speed, range, and fluid pattern of these monitors often cannot be flexibly adjusted according to different fire scenarios. Especially in situations requiring long-distance, high-pressure, or large-area firefighting, existing monitors often struggle to provide sufficient water jet impact, affecting firefighting effectiveness. Furthermore, the water flow pattern is not precise enough, prone to turbulence and instability, making it difficult to meet the need for accurate fire suppression.
[0003] Existing fire monitors also have significant shortcomings in terms of water flow acceleration and jet shaping. While some monitors possess certain adjustment capabilities, they typically rely solely on simple valve or nozzle structures, failing to effectively control the water flow pattern and velocity. Turbulence within the pipes leads to unstable jet flow, affecting accuracy and range. Furthermore, existing devices have limited rectification and diversion effects, making it difficult to generate a fine and powerful water jet. Especially under high-pressure conditions, precise flow control is impossible, resulting in reduced firefighting efficiency and an inability to adapt to complex firefighting scenarios. Utility Model Content
[0004] The purpose of this utility model embodiment is to provide a fire monitor jet shaping and acceleration device, which aims to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A fire monitor jet shaping and acceleration device includes a gradually expanding conical tube, one end of which is provided with a water outlet cylinder, and the other end of which is provided with a mounting panel.
[0007] The water outlet cylinder is detachably connected to a first mesh plate;
[0008] The inside of the gradually expanding tapered tube is provided with several shaping baffles at equal intervals along the circumference, and the sides of the several shaping baffles are connected to a shaping cylinder.
[0009] Furthermore, the surface of the first mesh plate is provided with an external fixing thread, and the inside of the water outlet cylinder is provided with an internal fixing thread. The first mesh plate is detachably connected to the inside of the water outlet cylinder through the cooperation of the external fixing thread and the internal fixing thread.
[0010] Furthermore, the surface of the mounting panel is provided with a number of mounting holes.
[0011] Furthermore, an adjusting ring is rotatably connected to the outer side of the water outlet cylinder, a support ring is provided inside the water outlet cylinder, a second mesh plate is connected to the side of the support ring, and the second mesh plate is located between the first mesh plate and the support ring. Several electromagnet blocks are installed inside the adjusting ring.
[0012] Furthermore, after the first perforated plate is securely assembled inside the water outlet cylinder, one side of the second perforated plate is in close contact with the surface of the support ring, and the other side of the second perforated plate is in close contact with the surface of the first perforated plate.
[0013] Furthermore, an annular groove is provided on the outer surface of the water outlet cylinder, and several arc-shaped sliders adapted to the shape of the annular groove are installed inside the adjusting ring. The adjusting ring is rotatably connected to the outside of the water outlet cylinder through the cooperation of the annular sliders and the arc-shaped groove.
[0014] Furthermore, the regulating ring is equipped with a built-in battery, and the built-in battery is electrically connected to the electromagnet block.
[0015] The fire monitor jet shaping and acceleration device provided by this utility model has the following beneficial effects:
[0016] The design of the gradually expanding conical tube achieves dual optimization of water jet velocity and fluid pattern, resulting in significant benefits. Firstly, the gradually decreasing inner diameter of the conical tube causes the water flow to accelerate continuously as it passes through the pipe, ensuring that the water reaches maximum velocity upon exiting the nozzle. This design enhances the impact force of the water flow, improving the effectiveness of long-distance fire suppression, and is particularly suitable for large-area or high-pressure fire suppression needs.
[0017] Secondly, the shaping baffles and shaping cylinders inside the device not only perform preliminary diversion and shaping of the water flow, effectively reducing turbulence within the pipe and ensuring a more stable and smooth flow, but also guide and accelerate the water flow, further enhancing the stability and speed of the jet. When the water flows through the first perforated plate, it is again evenly divided into multiple fine water columns, ensuring a more precise spraying effect, suitable for precise positioning fire extinguishing operations.
[0018] The overall design not only improves the range and accuracy of the water flow, but also enhances the ability to control the shape of the jet, thereby improving the overall performance of the fire monitor and providing strong support for rapid response and fire extinguishing efficiency in firefighting operations.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0029] like Figures 1-4As shown in the figure, the fire monitor jet shaping and acceleration device provided in this embodiment includes a gradually expanding conical tube 1, one end of which is provided with a water outlet tube 2, and the other end of which is provided with a mounting panel 4.
[0030] The water outlet cylinder 2 has a detachable first mesh plate 3 inside.
[0031] The interior of the gradually expanding tapered tube 1 is provided with several shaping baffles 8 at equal intervals along the circumference, and the sides of the several shaping baffles 8 are connected to the shaping cylinder 9.
[0032] In one embodiment of this utility model, the gradually expanding conical tube 1 is fixedly installed on the fire monitor via the mounting panel 4. When water flows into the interior of the gradually expanding conical tube 1, the flow velocity of the water gradually increases as the inner diameter of the tube gradually decreases. When the water reaches the end of the gradually expanding conical tube 1, its flow velocity reaches its maximum, and then it enters the outlet tube 2 and is sprayed out through the first mesh plate 3.
[0033] As the water flows through the gradually expanding conical pipe 1, several shaping baffles 8 and shaping cylinders 9 initially divert and shape the water flow, keeping it stable inside. When it passes through the first perforated plate 3, the water flow is further diverted and shaped by multiple holes on the perforated plate, and finally sprayed out in the form of several fine water jets.
[0034] In addition, since the shaping baffle 8 and the shaping cylinder 9 have a certain cross-sectional area, they not only play a shaping role, but also accelerate the water jet to a certain extent and enhance the jet effect by guiding the flow and reducing the turbulence effect.
[0035] Through the aforementioned technical solution, this fire monitor jet shaping and acceleration device, using the design of the gradually expanding conical tube 1, achieves dual optimization of water jet velocity and fluid morphology, resulting in significant beneficial effects. Firstly, the inner diameter of the gradually expanding conical tube 1 gradually decreases, causing the water flow to continuously accelerate as it passes through the pipe, ensuring that the water reaches its maximum velocity when it exits the water jet 2. This design enhances the impact force of the water flow, improving the effectiveness of long-distance fire extinguishing, and is particularly suitable for large-area or high-pressure fire extinguishing needs.
[0036] Secondly, the shaping baffles 8 and shaping cylinders inside the device not only perform preliminary diversion and shaping of the water flow, effectively reducing turbulence in the pipe and ensuring a more stable and smooth flow, but also guide and accelerate the water flow, further improving the stability and speed of the jet. When the water flows through the first perforated plate 3, it is again evenly divided into multiple fine water columns, ensuring a more precise spraying effect, suitable for precise positioning fire extinguishing operations.
[0037] The overall design not only improves the range and accuracy of the water flow, but also enhances the ability to control the shape of the jet, thereby improving the overall performance of the fire monitor and providing strong support for rapid response and fire extinguishing efficiency in firefighting operations.
[0038] In this embodiment, the surface of the first mesh plate 3 is provided with an external fixing thread 6, and the inside of the water outlet cylinder 2 is provided with an internal fixing thread 7. The first mesh plate 3 is detachably connected to the inside of the water outlet cylinder 2 through the cooperation of the external fixing thread 6 and the internal fixing thread 7.
[0039] This design offers several advantages. First, the threaded connection structure makes the installation and removal of the first perforated plate 3 extremely convenient, facilitating daily maintenance and cleaning, and extending the lifespan and efficiency of the device. Second, the threaded connection provides high stability, ensuring the perforated plate will not loosen under high-pressure water flow, guaranteeing flow control and jet shaping during the spraying process. Finally, this design also offers flexible replacement possibilities; users can replace the perforated plate with one of different aperture or structure to meet varying spraying requirements, further enhancing the device's applicability and versatility to satisfy the needs of different firefighting scenarios.
[0040] In this embodiment, the surface of the mounting panel 4 is provided with a plurality of mounting holes 5. This design has several advantages. First, the multiple mounting holes 5 provide a more flexible installation method, enabling the device to adapt to fire monitors of different sizes or installation requirements, thus enhancing its applicability. Second, the multiple holes make the mounting panel 4 more stable during installation, able to withstand greater water pressure, improving the stability and durability of the device. Simultaneously, the even distribution of the mounting holes 5 facilitates precise alignment during installation, simplifying the installation process, shortening operation time, and improving work efficiency. Furthermore, this design facilitates routine disassembly and maintenance, greatly simplifying equipment upkeep.
[0041] like Figure 5 and Figure 7 As shown, in one embodiment of this utility model, an adjusting ring 14 is rotatably connected to the outer side of the water outlet cylinder 2, and a support ring 11 is provided inside the water outlet cylinder 2. A second mesh plate 10 is connected to the side of the support ring 11, and the second mesh plate 10 is located between the first mesh plate 3 and the support ring 11. The second mesh plate 10 has the same outer diameter and aperture as the first mesh plate 3, but preferably a different thickness. The second mesh plate 10 is made of iron and has a moisture-proof coating on its surface to ensure its moisture-proof and durable performance.
[0042] Several electromagnet blocks 12 are installed inside the adjusting ring 14. Preferably, two electromagnet blocks 12 are provided and symmetrically installed on the adjusting ring 14 to enhance the positioning stability of the second mesh plate 10 and ensure its accurate positioning during operation.
[0043] After the first mesh plate 3 is securely assembled inside the water outlet cylinder 2, that is, after the external fixing thread 6 on the first mesh plate 3 is fully engaged with the second mesh plate 10 inside the water outlet cylinder 2, one side of the second mesh plate 10 is tightly attached to the surface of the support ring 11, and the other side of the second mesh plate 10 is tightly attached to the surface of the first mesh plate 3. Through the above-mentioned positional constraints, the second mesh plate 10 can rotate in a state of complete contact with the first mesh plate 3 during normal use of the device, meaning there are no gaps between them.
[0044] The outer surface of the water outlet cylinder 2 is provided with an annular groove. The inside of the adjusting ring 14 is equipped with several arc-shaped sliders that are adapted to the shape of the annular groove. The adjusting ring 14 is rotatably connected to the outside of the water outlet cylinder 2 through the cooperation of the annular sliders and the arc-shaped groove.
[0045] In this embodiment, when a strong current flows through the electromagnet 12, it generates a strong electromagnetic attraction force, firmly adsorbing the second mesh plate 10 and securing it stably between the first mesh plate 3 and the support ring 11. Simultaneously, the adjusting ring 14 is also stably fixed to the outside of the water outlet cylinder 2, ensuring the stability of the entire device under high-pressure water flow. When the current inside the electromagnet 12 weakens, the user can easily manually rotate the adjusting ring 14, causing the second mesh plate 10 to rotate between the first mesh plate 3 and the support ring 11, facilitating the adjustment of the water flow effect.
[0046] When it is necessary to change the thickness of the water jet ejected from the holes of the first perforated plate 3 or adjust the jet speed, the electromagnet block 12 is first set to a weaker current state. At this time, the user rotates the adjusting ring 14, causing the second perforated plate 10 to rotate between the first perforated plate 3 and the support ring 11. As the holes of the second perforated plate 10 gradually intersect with the holes of the first perforated plate 3, some of the water flow will be blocked by the solid area of the second perforated plate 10, reducing the thickness of the water jet and significantly increasing the jet speed.
[0047] When the holes of the first perforated plate 3 and the second perforated plate 10 are perfectly aligned, the water can flow smoothly, forming the thickest water jet. When the holes intersect, some of the water flow is blocked, the water jet becomes thinner, and the jet speed increases. Through this design, users can flexibly adjust the water flow pattern to adapt to different fire extinguishing needs.
[0048] The above technical solution achieves precise positioning and release of the second mesh plate 10 by adjusting the current of the electromagnet block 12, allowing users to easily adjust the water output state according to different fire extinguishing needs, and has many advantages.
[0049] First, the thickness and velocity of the water jet are precisely controlled. By controlling the current intensity of the electromagnet block 12, the second perforated plate 10 can be quickly and easily secured between the first perforated plate 3 and the support ring 11, ensuring it does not loosen under high-pressure water flow. Simultaneously, when the current decreases, the user can easily rotate the adjusting ring 14, allowing the second perforated plate 10 to rotate freely, thereby adjusting the position of the holes in the first and second perforated plates 3 and 10. Through this adjustment method, the thickness and velocity of the water jet can be precisely controlled. For example, when the holes are perfectly aligned, the water jet is thickest; when the holes are staggered, some water flow is blocked, the water jet becomes thinner, and the velocity increases. This design makes the device suitable for various firefighting scenarios, flexibly handling both wide-area mist sprays and long-distance columnar water jets.
[0050] Secondly, it is convenient and efficient to operate. The introduction of the electromagnet block 12 greatly simplifies the operation process. By controlling the strength of the current, the user can quickly switch the working state of the device. When the current is strong, the second mesh plate 10 remains fixed and stable; when the current is weak, the user can adjust the water flow effect by simply rotating the adjustment ring 14 manually. This convenient adjustment method reduces complex mechanical operations and greatly improves work efficiency, especially in emergency situations where the water cannon status can be quickly adjusted to adapt to different fire conditions.
[0051] Combined with previous technical solutions, this approach creates a stronger overall advantage. Firstly, the aforementioned solution, through the design of the gradually expanding conical tube 1, accelerates the water flow velocity, and the initial diversion and shaping by the shaping baffle 8 and shaping cylinder 9 ensures the stability and velocity of the water flow. The combination of this solution and the current one allows for further adjustment of the water flow pattern through the perforated plate system after acceleration and shaping, enabling diversified control of the water flow pattern. The gradually expanding conical tube 1 increases the water flow velocity, while the electromagnet-controlled perforated plate further refines the adjustability of the water flow pattern, thus giving the entire fire monitor device higher jet accuracy and adaptability.
[0052] In this embodiment, the adjusting ring 14 is equipped with a built-in battery 13, and the built-in battery 13 is electrically connected to the electromagnet block 12.
[0053] 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.
