Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire-fighting monitor device and fire-fighting equipment. Background Art

[0002] At present, the fire monitor on the fire truck is generally connected to the fire monitor through one interface of the three-way ball valve for fire extinguishing; and connected to the high-rise water supply pipe through the other interface of the three-way ball valve for high-rise water supply. However, the above method of controlling the fire monitor and the high-rise water supply pipe through the three-way ball valve requires an elbow to be arranged at the high-rise water supply pipe position to ensure that the water outlet direction of the high-rise water supply pipe can supply water to the high-rise. This elbow structure increases the lateral moment of the high-rise water supply pipeline and causes large losses along the way. It is necessary to control the reversing opening and closing of the three-way ball valve to achieve the switching between the fire monitor operation and the high-rise water supply operation. Moreover, due to the existence of the high-rise water supply pipe and the three-way ball valve, it also has the problem of occupying a large space and being heavy. Utility Model Content

[0029] The following combination Figure 1-Figure 3 The present invention describes a fire monitor device. The fire monitor device comprises: a fire monitor body 2, a connecting component 3, a nozzle 5 and a water hose 4. The fire monitor device has two optional installation states:

[0030] 1. In the first state, one end of the connecting component 3 is detachably connected to the muzzle of the fire monitor body 2, and the other end of the connecting component 3 is used to connect the water hose 4;

[0031] 2. In the second state, the nozzle 5 is detachably connected to the muzzle of the fire monitor body 2.

[0032] The muzzle of the fire monitor body 2 can be detachably connected to either the connecting component 3 or the nozzle 5. Specifically, in the first state, Figure 1As shown, the nozzle 5 on the muzzle of the fire monitor body 2 is removed, the connecting component 3 is replaced, the connecting component 3 is installed on the muzzle of the fire monitor body 2, and the connecting component 3 is connected to the water hose 4. The three-way ball valve and the bypass high-rise water supply pipeline are cancelled, and the water supply from the fire monitor is used as the water source for the high-rise water supply.

[0033] In the second state, if Figure 2 As shown, the connecting component 3 and the water hose 4 on the muzzle of the fire monitor body 2 are removed, the nozzle 5 is replaced, and the nozzle 5 is installed on the muzzle of the fire monitor body 2. Water can be supplied to the fire monitor body 2 through water supply equipment to realize water spraying fire extinguishing operation, and foam can also be provided to the fire monitor body 2 through foam fire extinguishing equipment to realize foam fire extinguishing operation.

[0034] In summary, the utility model provides a fire cannon device, which eliminates the three-way ball valve and the bypass high-rise water supply pipeline. The entire device is not equipped with elbows, has no lateral deflection moment, reduces losses along the way, occupies a small space, and has a light weight. By installing or removing the connecting component 3, the gun nozzle 5 and the water hose 4, the multifunctionality of the fire cannon is realized, that is, three operating modes of water spraying, foam spraying and high-rise water supply are realized.

[0035] The present invention provides a fire monitor device comprising: a fire monitor body 2, a connecting component 3, a nozzle 5, and a hose 4. The fire monitor device has two optional installation positions: 1. In the first position, one end of the connecting component 3 is detachably connected to the muzzle of the fire monitor body 2, and the other end of the connecting component 3 is used to connect to the hose 4; 2. In the second position, the nozzle 5 is detachably connected to the muzzle of the fire monitor body 2. The fire monitor device provided by the present invention eliminates one waterway in conventional fire monitor devices, as well as the three-way ball valve and bypass high-rise water supply pipeline structure. By using only one waterway, the entire fire monitor device has the advantages of small footprint and light weight. Furthermore, the entire device lacks elbows, eliminating the lateral moment problem caused by elbows and reducing losses along the way. Because the fire monitor device can be switched between water spraying, foam spraying, and high-rise water supply modes by installing, removing, and replacing the connecting components, hose, and nozzle, the multifunctional fire monitor device achieves this.

[0036] In one embodiment of the present invention, the other end of the connecting component 3 is detachably connected to the hose 4. The connecting component includes a first interface 33 and a second interface 34, which are interconnected. The first interface 33 is detachably connected to the muzzle of the fire monitor body 2, and the second interface 34 is used to connect to the hose 4. Specifically, the connecting component 3 in this embodiment is a tubular structure, with the first interface 33 used to communicate with the muzzle, and the second interface 34 used to communicate with the hose, thereby ensuring water supply from the muzzle to the hose.

[0037] In one embodiment of the present invention, the muzzle of the fire monitor body 2 is detachably connected to the connecting component 3 via a threaded connection. Similarly, the nozzle 5 is also threadedly connected to the fire monitor body 2. When the connecting component 3 / nozzle 5 needs to be replaced, the nozzle 5 / connecting component 3 on the muzzle is unscrewed and the corresponding connecting component 3 / nozzle 5 is screwed on to achieve the corresponding installation state of the fire monitor device. In this embodiment, the threaded structure is provided to achieve a detachable connection between the muzzle of the fire monitor body 2 and the connecting component 3 / nozzle 5, which facilitates on-site installation and removal by firefighters, and has a simple structure and is easy to process.

[0038] In one embodiment of the present invention, in the embodiment of the above-mentioned threaded connection, there are two different structural arrangements: 1. The muzzle of the fire monitor body 2 is formed with a first internal thread, and the connecting component 3 is formed with a first external thread, and the first external thread and the first internal thread are engaged with each other; 2. The muzzle of the fire monitor body 2 is formed with a second external thread, and the connecting component 3 is formed with a second internal thread 31, and the second external thread and the second internal thread 31 are engaged with each other. Taking the second structural arrangement as an example, Figure 3 As shown, a second internal thread 31 is formed on the left end of the connecting component 3, which interlocks with the second external thread formed on the muzzle of the fire monitor body 2. By rotating the connecting component 3, a sealed connection between it and the muzzle of the fire monitor body 2 can be achieved. Of course, depending on the different thread structures used in the muzzle of the fire monitor body 2, the connecting component 3 can also adopt the first type of internal thread form to ensure a sealed connection between the two.

[0039] In one embodiment of the present invention, the connecting component 3 and the water hose 4 are detachably connected via a snap-fit ​​structure. In this embodiment, the connecting component 3 and the water hose 4 are sealed by the snap-fit ​​structure. When the water hose 4 needs to be installed, the water hose 4 is aligned and inserted into the end of the connecting component 3 and the water hose 4 is rotated. The snap-fit ​​structure seals the two. When the water hose 4 needs to be removed, it only needs to be rotated in the opposite direction to remove it from the connecting component 3.

[0040] In one embodiment of the present invention, the connecting component 3 is formed with a first protrusion structure 32 arranged symmetrically along the axial direction, and a groove structure is formed between each two adjacent first protrusion structures 32. The water hose 4 is formed with a second protrusion structure arranged symmetrically along the axial direction. The second protrusion structure is suitable for passing through the groove structure and snapping onto one side of the first protrusion structure 32. In this embodiment, the sealing connection between the connecting component 3 and the water hose 4 is achieved by snapping the protrusion structure (i.e., the protrusion structure mentioned above). The sealing installation can be completed by simply rotating the water hose 4. Specifically, Figure 3As shown, two first protrusion structures 32 are provided on the inner wall of the right end of the connecting component 3, and a groove structure for the second protrusion structure to pass through is formed between the two first protrusion structures 32 and between the two protrusions. When the water hose 4 is inserted into place, the water hose 4 is rotated so that the second protrusion structure is opposite to the first protrusion structure 32, and the two are snap-connected, and the water hose 4 is installed; when the water hose 4 needs to be removed, the water hose 4 is rotated so that the second protrusion structure is opposite to the groove structure, and the water hose 4 can be pulled out from the connecting component 3.

[0041] In one embodiment of the present invention, the first interface 33 has a constricted structure at the end closest to the monitor body 2, while the second interface 34 has a flared structure at the end closest to the hose 4. In this embodiment, the design of the ports on the monitor body 2 ensures that the inner diameter of the first interface 33 is the same as the inner diameter of the second interface 34, thereby ensuring that the flow rates of the hose 4 and the monitor body 2 are consistent. Specifically, due to the design of the raised structure in the above embodiment, to ensure that the hose 4 can be inserted into the connecting component 3, the outer diameter of the hose 4 should not be larger than the inner diameter of the circle containing the first raised structure 32. Therefore, the end of the connecting component 3 that connects to the hose 4 is designed with a flared structure, ensuring that the caliber of the hose 4 is substantially the same as that of the monitor body 2.

[0042] In one embodiment of the present invention, the fire monitor device further includes: a pressure sensor 1, which is provided on the water supply pipeline of the water supply equipment and is used to monitor the water supply pressure in the first state or the second state. Since the present device has three working modes, it is necessary to consider the pressure protection strategy of the fire monitor. In this embodiment, the internal pressure is monitored by the pressure sensor 1 to ensure the overall safety of the device. Specifically, under normal circumstances, the inlet pressure of the fire monitor in the fire extinguishing operation mode is below 1.0MPa, and the inlet pressure of the fire monitor in the high-rise water supply mode is below the maximum working pressure (usually 1.6MPa). When switching the working mode, the system needs to give instructions to adjust and control the pressure by adjusting the engine speed, and monitor and feedback in real time through the pressure sensor 1, so that the fire monitor is always in a safe state during use.

[0043] In one embodiment of the present invention, the fire monitor device further includes an image acquisition device 6, which is disposed on the fire monitor body 2. Specifically, the image acquisition device 6 can be a conventional image sensor, such as a camera, or an infrared sensor. During water and foam spraying operations, the image acquisition device 6 can be used to observe fire scene information and transmit video to the control center for timely response.

[0044] In one embodiment of the present invention, the fire monitor device further comprises: a mounting base 7, the mounting base 7 is fixed on the fire monitor body 2, and the image acquisition device 6 is arranged on the mounting base 7. Figure 2As shown, a mounting base 7 is fixed on the upper surface of the fire monitor body 2, which can be fixed by bolts. The image acquisition device 6 is installed through the mounting base 7. A plurality of positioning holes are provided on the mounting base 7. The image acquisition device 6 is fixed on the mounting base 7 by passing bolts through the positioning holes to ensure the installation stability of the image acquisition device 6.

[0045] The present invention also provides a firefighting device, which may be a fire truck, comprising: a water supply device or a foam fire extinguishing device and a fire monitor device according to the above embodiment of the present invention; the fire monitor device is connected to the water supply device or the foam fire extinguishing device.

[0046] The fire-fighting equipment provided by the present invention has the same advantages as above because it includes the fire monitor device in the above embodiment of the present invention.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
