Description

Technical Field

[0001] This utility model belongs to the field of fire protection equipment technology, and specifically relates to a water jet direction indicator device for fire monitors. Background Technology

[0002] Fire monitors are important firefighting equipment for long-range fire suppression and are widely used in petrochemical plants, ports, large warehouses, and other locations. Existing fire monitors are typically operated by personnel using a handle or remote control to adjust the elevation and swivel angles, thereby controlling the direction of the water jet.

[0003] However, in actual firefighting operations, especially at night when visibility is limited, it is difficult for operators to clearly and accurately determine the precise landing point of the water jet. Multiple test shots and adjustments are often required, wasting valuable firefighting time and large amounts of water resources, and potentially delaying the optimal firefighting opportunity due to inaccurate positioning.

[0004] Therefore, how to achieve rapid and accurate positioning of fire monitors has become a technical problem that urgently needs to be solved. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a fire monitor with a water jet direction indicator that can provide clear direction to the operator through a visible laser beam, thereby achieving rapid and accurate fire extinguishing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fire monitor water jet direction indicator device, including a jet gun body and a fixed bracket clamped and fixed to the periphery of the jet gun body, wherein a firing angle adjustment seat is detachably connected to the fixed bracket; The firing angle adjustment seat includes a slide block slidably connected to the fixed bracket, a ball joint seat fixedly connected to the slide block, and a mounting hinge seat hinged to the ball joint seat; The slide block is threaded with a fastening bolt 1, one end of which can abut against the fixed bracket; the ball joint is threaded with a fastening bolt 2, which can abut against the mounting hinge. A laser emitter is provided on the mounting hinge, and the laser beam emitted by the laser emitter is used to indicate the landing point of the water column ejected by the jet gun body.

[0007] Optionally, the ball joint includes a first hinge fixedly connected to the slide, a second hinge mating with the end of the first hinge, and a connecting sleeve sleeved on the outer periphery of the first hinge and the second hinge. The connecting sleeve has several through holes for fastening bolts three to pass through, and the fastening bolts three can be threaded to the first hinge or the second hinge. The hinge seat 1 and the hinge seat 2 are connected at one end to form a spherical cavity, and the end of the hinge seat is provided with a ball head that can be movably embedded in the spherical cavity.

[0008] Optionally, a rubber gasket is provided at the end of the fastening bolt that is threaded into the ball joint seat.

[0009] Optionally, the fixed bracket includes an arc-shaped bracket one and an arc-shaped bracket two, which can be arranged around the periphery of the jet gun body, and the two ends of the arc-shaped bracket one and the arc-shaped bracket two can be fastened together by bolts.

[0010] Optionally, both the first and second arc-shaped frames are provided with arc-shaped rubber pads on one side that fits against the outer periphery of the jet gun body.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0018] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. 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. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] like Figures 1-4 As shown, a fire monitor uses a water jet direction indicator device, including a jet body 1 and a fixed bracket 2 clamped and fixed to the outer periphery of the jet body 1. The jet body 1 is one of the main components of the fire monitor, which also includes a multi-directional rotating seat for connecting the jet body 1, allowing the jet body 1 to rotate left and right and up and down.

[0020] The fixed bracket 2 is detachably connected to an angle adjustment seat. The angle adjustment seat includes a slide 3 slidably connected to the fixed bracket 2, a ball joint seat 4 fixedly connected to the slide 3, and a mounting hinge seat 5 hinged to the ball joint seat 4. The slide 3 is threaded with a fastening bolt 6, one end of which abuts against the fixed bracket 2, to fix the position of the slide 3 on the fixed bracket 2. The ball joint seat 4 is threaded with a fastening bolt 7, which abuts against the mounting hinge seat 5. Both the bolt heads of the fastening bolts 6 and 7 have anti-slip textures on their outer circumference, allowing the operator to fix the position of the slide 3 on the fixed bracket 2 and the position of the mounting hinge seat 5 on the ball joint seat 4 without the need for additional tools. It should be noted that in this technical solution, a laser emitter 8 is installed on the mounting hinge 5. Since the mounting hinge 5 is hinged to the ball joint 4, the operator can adjust the angle at which the mounting hinge 5 is hinged to the ball joint 4 to adjust the laser beam emitted by the laser emitter 8 to correspond to the landing point of the water column ejected from the jet gun 1. Specifically, it can indicate the final landing point of the water column or be parallel to the flight path of the water column, thus providing the operator with a clear and visible aiming reference.

[0021] Specifically, in this embodiment, the laser emitter 8 can be a visible red laser or a visible green laser, which are conventional technologies, to ensure that the laser beam emitted by the laser emitter 8 still has high recognizability in complex environments. Moreover, the laser emitter 8, which is mounted by the fixed bracket 2 and the angle adjustment seat, can be set above, to the side or below the jet gun body 1, or in a position that does not affect the normal rotation of the jet gun body 1 and facilitates the emission of light.

[0022] In actual use, the operator first activates the laser emitter 8 in its initial position. At this time, the laser beam emitted by the laser emitter 8 is parallel to the flight path of the water jet (the section of the water jet that does not fall due to gravity) ejected from the jet cannon 1. There is no need to open the water supply valve of the jet cannon 1 at this point. The operator then adjusts the angle of the jet cannon 1 so that the laser beam's landing point is moved to a target area closer to the center of the fire (this area, under the firelight, can provide illumination for the water jet's landing point). Subsequently, the operator can briefly open the water supply valve and keep the position of the jet cannon 1 fixed. After determining the water jet's landing point, the operator can adjust the laser beam's landing point in the target area so that it aligns with the water jet's landing point. After re-fixing the position of the laser emitter 8, the operator can then continuously open the water supply valve of the jet cannon 1. At this point, the water jet ejected by the jet cannon 1 will accurately target the laser beam's landing point, thus achieving rapid and accurate positioning of the fire monitor.

[0023] Furthermore, in this technical solution, such as Figure 2 , Figure 4As shown, for ease of assembly, the ball joint seat 4 adopts a split design. Specifically, the ball joint seat 4 includes a hinge seat 41 fixedly connected to the slide 3, a hinge seat 42 abutting the end of the hinge seat 41, and a connecting sleeve 43 sleeved around the outer periphery of the hinge seat 41 and the hinge seat 42. The connecting sleeve 43 has several through holes 431 reserved for fastening bolts 3 (not shown in the figure) to pass through, and the fastening bolts 3 can be threaded to the hinge seat 41 or the hinge seat 42. Among them, the abutting ends of the hinge seat 41 and the hinge seat 42 form a spherical cavity 412, and the end of the mounting hinge seat 5 is provided with a ball head 51 that can be movably embedded in the spherical cavity 412. It should be noted that the fastening bolt 2 7 is threaded and passes through the hinge seat 2 42. The end of the fastening bolt 2 7 bolted into the hinge seat 2 42 can abut against the ball head 51 on the mounting hinge seat 5 to fix the position of the mounting hinge seat 5 relative to the ball joint seat 4.

[0024] Meanwhile, in this technical solution, to increase the positional stability of the laser emitter 8, such as Figure 4 As shown, a rubber pad 9 is provided at the end of the fastening bolt 7 that is threaded into the ball joint seat 4. That is, the friction between the fastening bolt 7 and the ball head 51 can be increased by squeezing the rubber pad 9, so as to prevent the laser emitter 8 from sliding relative to each other.

[0025] Furthermore, to facilitate the installation of the fixing bracket 2 on the jet gun body 1, such as... Figure 2 As shown, the fixed bracket 2 includes an arc-shaped bracket 21 and an arc-shaped bracket 22. The arc-shaped bracket 21 and the arc-shaped bracket 22 can be arranged around the outer periphery of the jet gun body 1, and the two ends of the arc-shaped bracket 21 and the arc-shaped bracket 22 can be fastened together by bolts.

[0026] It should be noted that arc-shaped rubber pads 10 are provided on the side of arc-shaped frame 1 21 and arc-shaped frame 22 that are attached to the outer periphery of the jet gun body 1, in order to increase the stability of arc-shaped frame 1 21 and arc-shaped frame 22 fixedly clamped to the jet gun body 1.

[0027] As described above, the arc-shaped frame 21 is provided with a dovetail groove 211, and the slide block 3 is provided with a dovetail part 31 that slides and engages with the dovetail groove 211. One end of the fastening bolt 6 can abut against the arc-shaped frame 21 to fix the position of the slide block 3 relative to the fixed bracket 2.

[0028] In this embodiment, the laser emitter 8 can be powered by a built-in battery or connected to the existing power supply of the fire monitor via a cable to achieve unified power supply management.

[0029] Working principle: By adding a laser emitter 8 to the jet cannon body 1, the laser beam emitted by the laser emitter 8 can provide clear visual instructions for the operator to adjust the direction of the water jet of the jet cannon body 1, enabling the operator to intuitively and quickly aim the water jet at the fire source, avoiding blind test firing, and greatly improving the accuracy and efficiency of fire extinguishing.

[0030] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
