Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a hydraulically self-swinging fire monitor. Background Technology

[0002] A hydraulically powered self-oscillating fire monitor is a fire-fighting device that uses the kinetic energy of water flow to drive the automatic oscillation of the spray pipe. Its core feature is that it requires no external electricity or hydraulic power; it can achieve horizontal reciprocating oscillation solely through water pressure and kinetic energy, thereby expanding the fire-fighting coverage area and improving fire-fighting efficiency.

[0003] In related technologies, water flow from the inlet to the outlet of a fire monitor will experience significant energy loss, causing internal flow field turbulence. This results in high turbulence at the outlet of the fire monitor, premature dispersion of the water jet, and affects the focus and range of the water cannon jet. Utility Model Content

[0004] This application discloses a hydraulically self-swinging fire monitor to solve the technical problem of large water flow energy loss in related technologies.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] This application discloses a hydraulically self-swinging fire monitor, comprising:

[0007] The first pipe has one end connected to a water source;

[0008] The second pipe is rotatably connected to the other end of the first pipe; the second pipe can rotate horizontally relative to the first pipe.

[0009] A drive assembly includes an impeller and a drive component; the impeller is rotatably disposed in a second pipe, and a portion of the impeller is located inside the second pipe; one end of the drive component is connected to the impeller, and the other end is connected to the first pipe;

[0010] When water flows through the impeller, the impeller rotates, and the driving component drives the second pipe to rotate reciprocally.

[0011] In some designs, the drive components include a worm gear, a worm, and a connecting part;

[0012] The worm gear is rotated in the second pipe, the worm meshes with the worm wheel, and one end of the worm is also connected to the impeller;

[0013] One end of the connector is connected to the first pipe, and the other end is connected to the worm gear.

[0014] In some designs, the connecting part includes a connecting rod and a turntable;

[0015] The turntable and worm gear are coaxially arranged. One end of the connecting rod is rotatably connected to the second pipe, and the other end is rotatably connected to the turntable and is eccentrically arranged.

[0016] In some designs, the first conduit includes a water cannon base and a connecting pipe;

[0017] One end of the connecting pipe is vertically rotatably connected to the water cannon base via a ball-and-socket structure, and the other end is horizontally rotatably connected to the second pipe via a ball-and-socket structure.

[0018] One end of the connecting part is connected to the connecting pipe.

[0021] In some designs, the top of the second pipe has a mounting section, the impeller is rotatably disposed within the mounting section, and at least a portion of the impeller extends into the second pipe.

[0022] In some designs, there is an angle between the axis of the first pipe and the axis of the second pipe.

[0023] In some designs, the first or second conduit is equipped with a valve that can be opened and closed.

[0024] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0025] This application's hydraulically self-oscillating fire monitor involves a high-pressure water jet passing sequentially through a first pipe and a second pipe, exiting from the second pipe. Within the second pipe, the high-pressure water jet passes through an impeller, causing it to rotate. This rotation, via a drive component, propels the second pipe to reciprocate horizontally, thus expanding the spray coverage area. As the water jet passes the impeller, only a portion of it is located within the second pipe. This efficiently captures the kinetic energy of the water jet to drive its oscillation while minimizing encroachment on the cross-sectional area of ​​the second pipe and reducing flow field disturbance. This maintains the continuity of the water jet's axial momentum, preventing eddy separation caused by mechanical resistance. The water jet remains within a laminar core region at the outlet, significantly improving jet concentration and range. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0038] The inventors discovered during use that in the related technology, the main structure of the driving component of the hydraulic self-swinging fire monitor is located entirely inside the fire monitor body. This causes abrupt changes in the cross-section of the fire monitor body, resulting in significant energy loss during the water flow from the inlet to the outlet of the fire monitor. This causes internal flow field turbulence, leading to high turbulence at the outlet of the fire monitor, premature dispersion of the water column, and affecting the focus and range of the water jet.

[0039] The following is in conjunction with the appendix Figures 1 to 5 The present application provides a detailed description of a hydraulically self-swinging fire monitor through specific embodiments and application scenarios.

[0040] Some embodiments of this application provide a hydraulically self-swinging fire monitor, including a first pipe 100, a second pipe 200, and a drive assembly 300.

[0041] like Figures 1-3 and Figure 5 As shown, one end of the first pipe 100 is used to connect to a water source, and the other end is rotatably connected to the second pipe 200. By connecting the water source through the first pipe 100, high-pressure water flows sequentially through the first pipe 100 and the second pipe 200, and is sprayed out from the second pipe 200 to the outside.

[0042] like Figures 1-3 As shown, the second pipe 200 can rotate horizontally relative to the first pipe 100. Since the water flow is sprayed to the outside from the second pipe 200, the coverage area of ​​the water flow can be increased by allowing the second pipe 200 to rotate horizontally relative to the first pipe 100.

[0043] Among them, the horizontal direction is as follows Figure 2 As shown in O1, the same applies below.

[0044] like Figure 3 and Figure 5 As shown, the drive assembly 300 includes an impeller 310 and a drive component 320. The impeller 310 is rotatably mounted on the second pipe 200, and a portion of the impeller 310 is located within the second pipe 200. When the water flows through the impeller 310, since only a portion of the impeller 310 is located within the second pipe 200, it efficiently captures the kinetic energy of the water flow to drive the oscillation, while reducing the encroachment on the cross-sectional area of ​​the second pipe 200 and the disturbance to the flow field. This maintains the continuity of the axial momentum of the water flow, avoids vortex separation caused by mechanical resistance, and keeps the water column in a laminar core region at the outlet, significantly improving the jet concentration and range.

[0045] like Figure 5As shown, one end of the drive unit 320 is connected to the impeller 310, and the other end is connected to the first pipe 100. When water flows through the impeller 310, the impeller 310 rotates, and the drive unit 320 drives the second pipe 200 to rotate back and forth. The kinetic energy of the water flow drives the second pipe 200 to swing, without the need for an additional power source.

[0046] like Figure 5 As shown, the driving component 320 includes a worm gear 322, a worm 321, and a connecting part 330. The worm gear 322 is rotatably mounted on the second pipe 200, and the worm 321 meshes with the worm gear 322, with one end of the worm 321 also connected to the impeller 310. One end of the connecting part 330 is connected to the second pipe 200, and the other end is connected to the worm gear 322. When water flows through the impeller 310, the impeller 310 rotates using the kinetic energy of the water flow and transmits torque to the worm 321. The worm 321 then drives the worm gear 322 to rotate. Under the rotation of the worm gear 322, the connecting part 330 causes the second pipe 200 to reciprocate in the horizontal direction.

[0047] like Figure 5 As shown, the connecting part 330 includes a connecting rod 331 and a turntable 332. The turntable 332 is coaxially arranged with the worm gear 322. One end of the connecting rod 331 is rotatably connected to the first pipe 100, and the other end is rotatably connected to the turntable 332 and eccentrically arranged. Since the turntable 332 and the worm gear 322 are coaxially arranged, the turntable 332 and the worm gear 322 rotate synchronously, and the second pipe 200 is driven to rotate through the connecting rod 331 eccentrically connected to the turntable 332. As the worm gear 322 rotates, the second pipe 200 is driven to oscillate back and forth in the horizontal direction under the action of the connecting rod 331.

[0048] like Figure 1 As shown, the first pipe 100 includes a water cannon base 110 and a connecting pipe 120. One end of the connecting pipe 120 is rotatably connected to the water cannon base 110 in the vertical direction via a ball joint structure 121, and the other end is rotatably connected to the first pipe 100 in the horizontal direction via a ball joint structure 121. The connecting pipe 120 connects the water cannon base 110 and the second pipe 200, facilitating the assembly of the water cannon base 110, the connecting pipe 120, and the second pipe 200. Furthermore, it allows for the individual replacement of the second pipe 200 or the sealing components between different parts without disassembling the water cannon base 110, reducing operation time.

[0049] Furthermore, one end of the connecting pipe 120 is rotatably connected to the water cannon base 110 in the vertical direction via the ball socket structure 121, and the other end is rotatably connected to the first pipe 100 in the horizontal direction via the ball socket structure 121. This allows the second pipe 200 to rotate in the horizontal direction while also adjusting the spray angle of the second pipe 200 to meet operational requirements.

[0050] Among them, the vertical direction is as follows Figure 3 As shown in the O2.

[0051] In this embodiment, one end of the connecting part 330 is connected to the connecting pipe 120. Specifically, one end of the connecting rod 331 is rotatably connected to the connecting pipe 120, and the other end is rotatably connected to the turntable 332 and arranged eccentrically.

[0052] like Figure 3 As shown, the inner diameters of the connection between the connecting pipe 120 and the water cannon base 110 are the same. This design, which maintains the same inner diameter at the connection between the connecting pipe 120 and the water cannon base 110, eliminates abrupt changes in the cross-sectional area of ​​the flow channel, avoiding turbulent separation and local pressure drop caused by sudden changes in flow velocity, thereby significantly improving the jet's focusing ability and range.

[0053] like Figure 3 As shown, the inner diameters of the connection between the second pipe 200 and the connecting pipe 120 are the same. This design, where the inner diameters of the connecting pipe 120 and the second pipe 200 are the same, eliminates abrupt changes in the flow channel cross-sectional area, avoiding turbulent separation and local pressure drops caused by sudden changes in flow velocity, thereby significantly improving the jet's focusing ability and range.

[0054] like Figure 3 As shown, the top of the second pipe 200 has a mounting portion 211, and the impeller 310 is rotatably disposed within the mounting portion 211, with at least a portion of the impeller 310 extending into the second pipe 200. By providing the mounting portion 211 at the top of the second pipe 200, mounting space is provided for the impeller 310, ensuring that at least a portion of the impeller 310 extends into the second pipe 200 while also ensuring a seal at the mounting point of the impeller 310, preventing water from overflowing.

[0055] like Figure 3 As shown, there is an angle between the axis of the first pipe 100 and the axis of the second pipe 200. Since water is ejected from the second pipe 200, the angle between the first pipe 100 and the second pipe 200 can raise the position and angle of the outlet of the second pipe 200, so that the water can be ejected further.

[0056] The first pipe 100 or the second pipe 200 is equipped with an openable and closable valve. By installing a valve on the first pipe 100 or the second pipe 200, the opening or closing of the hydraulic self-oscillating fire monitor can be easily controlled.

[0057] In some embodiments, a valve is provided in the first conduit 100.

[0058] In some embodiments, a valve is provided in the second pipe 200.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0060] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved.
