Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "first" and "second" are only used for descriptive purposes, and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figure 1-11 , the present invention provides a technical solution: The first embodiment is a low-speed self-swinging mobile fire monitor, comprising: A low-speed rotating adjustment seat 2, comprising a first reduction motor 21; The output upper end of the first reduction motor 21 is fixedly assembled with a hinge seat 22 via a connecting flange; The fire monitor body 3 has its lower end hinged in the hinge seat 22, and the output end of the fire monitor body 3 is a booster gun head 4; A second reduction motor 23 is fixedly mounted on the side wall of the articulated seat 22 , and an output end thereof passes through the side wall of the articulated seat 22 and is fixedly connected to the lower end of the fire monitor body 3 .

[0023] Specifically in this embodiment, the first reduction motor 21 and the second reduction motor 23 used in the low-speed rotation adjustment seat 2 are both worm gear reducers, which have the effect of low speed and high torque; Furthermore, the first reduction motor 21 is used to drive the articulated seat 22 to rotate 360 ​​degrees at a horizontal angle, and the articulated seat 22 drives the fire monitor body 3 articulated thereto to rotate accordingly; the second reduction motor 23 is used to drive the fire monitor body 3 articulated in the articulated seat 22 to perform pitch rotation; More specifically, the fire monitor body 3 swings horizontally at a low speed of 5° / second, and adjusts the elevation angle every 30 seconds, with a low-speed swing of the elevation angle from -15° to +75°, forming a three-dimensional covering water curtain; through the cooperation of the booster gun head 4 and the low-speed swing, the spray water volume and water flow impact force on the same area are increased in unit time, thereby improving the fire extinguishing effect; It can be understood that the device is suitable for use at fire scenes with a low risk of small-scale fire spread, and can be used in isolated scenes in forest fires to avoid the spread of fire caused by low-speed swinging.

[0024] In the embodiment, it also includes a chassis 5, which is electrically connected to the first reduction motor 21 and the second reduction motor 23 respectively; The chassis 5 is wirelessly connected to a remote controller 6 .

[0025] Specifically in this embodiment, the chassis 5 is used to wirelessly connect to the remote controller 6, and control the operation of the first reduction motor 21 and the second reduction motor 23 according to the control signal sent by the remote controller 6; Furthermore, the first reduction motor 21 rotates 360 degrees and then reverses to reset to avoid entanglement of the water pipe. The second reduction motor 23 rotates within a pitch angle range of -15° to +75°. The rotation ranges of the two are controlled by a controller 54 in the chassis 5. The programming control of the controller 54 is an application of the prior art and will not be described in detail here. More specifically, the signal sent by the remote controller 6 is transmitted to the controller 54, and the controller 54 controls whether the first reduction motor 21 and the second reduction motor 23 are working, and controls the working status of both. This is equivalent to the remote controller 6 only being able to control whether the first reduction motor 21 and the second reduction motor 23 are working, but not controlling the working status of the first reduction motor 21 and the second reduction motor 23; It is understandable that the remote controller 6 adopts a 2.4G wireless remote controller with an effective distance of 30-50 meters. Its strong penetration and stability can realize remote control operation at a long distance and will not be disturbed by light, so it is suitable for outdoor environments.

[0026] In an embodiment, the booster gun head 4 comprises: A booster gun barrel 41, one end of which has an inner wall provided with a first internal thread 42; The outer wall of the output end of the fire monitor body 3 is provided with an external thread, and the first internal thread 42 is screwed to the outer wall of the output end of the fire monitor body 3; The other end of the booster gun barrel 41 is coaxially fixedly connected to a conical nozzle 43 .

[0027] Specifically in this embodiment, the water flow is concentratedly sprayed from the conical nozzle 43 under the pressure of the booster gun tube 41, which can effectively increase the water flow spray distance, increase the impact force of the water flow on the fire source, and increase the amount of water output per unit time; Furthermore, the booster gun barrel 41 is connected to the external thread provided on the outer wall of the output end of the fire monitor body 3 through the first internal thread 42, so as to facilitate the disassembly and replacement of other types of booster gun heads 4.

[0028] In an embodiment, the pressurized gun barrel 41 comprises: The first gun tube 411 has an inner cavity which is coaxially provided with a first cylindrical cavity 414, a second cylindrical cavity 413 and a third cylindrical cavity 412 which are connected from the side close to the fire monitor body 3 to the side away from the fire monitor body 3; The inner diameters of the first cylindrical cavity 414 , the second cylindrical cavity 413 and the third cylindrical cavity 412 become smaller in sequence, and spiral guide vanes 415 of matching sizes are fixedly mounted in the three.

[0029] Specifically in this embodiment, the output water flow is pressurized step by step by the first cylindrical cavity 414, the second cylindrical cavity 413 and the third cylindrical cavity 412, whose inner diameters are successively smaller, and the pressurized water flow is spirally guided by the spiral guide plate 415. Due to the vortex effect of the water flow, it can maintain a longer straight line motion in the air, thereby achieving a longer spraying distance; It can be understood that the corners at the connection between the first cylindrical cavity 414, the second cylindrical cavity 413 and the third cylindrical cavity 412 are all rounded to reduce the resistance to water jetting.

[0030] In an embodiment, the chassis 5 comprises: The chassis housing 51 has an opening at one end of its side wall; A charging power source 53, a controller 54 and a wireless communication module 55 are fixedly mounted in the middle of the inner cavity of the chassis housing 51; The controller 54 is electrically connected to the charging power source 53, the wireless communication module 55, the first reduction motor 21 and the second reduction motor 23 respectively; The wireless communication module 55 is connected to the remote controller 6 via wireless communication.

[0031] Specifically in this embodiment, the charging power supply 53 supplies power to the circuits where the controller 54, the wireless communication module 55, the first reduction motor 21 and the second reduction motor 23 are located. Specifically, the charging power supply 53 is a rechargeable battery. A window corresponding to the charging interface of the rechargeable battery is provided on the side wall of the chassis housing 51 to facilitate charging of the rechargeable battery. Furthermore, the wireless communication module 55 is wirelessly connected to the remote controller 6, and the wireless communication module 55 transmits the received control signal of the remote controller 6 to the electrically connected controller 54, and controls whether the first reduction motor 21 and the second reduction motor 23 are working, and controls the working status of the two through the controller 54; It can be understood that an opening is provided on one side of the chassis shell 51 for heat dissipation of the device, and the open side is facing away from the fire source when in use, thereby reducing the impact of the fire source on the chassis 5.

[0032] In the embodiment, the outer wall of the chassis housing 51 away from the opening side is uniformly provided with through holes 57; A cooling fan 56 is fixedly mounted on the inner cavity of the chassis housing 51 near the through hole 57 and is electrically connected to the controller 54 and the charging power source 53; The wind direction of the heat dissipation fan 56 is toward the opening of the chassis housing 51 .

[0033] Specifically in this embodiment, the cooling fan 56 can be controlled to be turned on and off by the remote controller 6, and when the cooling fan 56 is turned on, the chassis 5 enters the forced cooling mode; Furthermore, when the cooling fan 56 is turned on, air is taken in from the through hole 57 on the chassis shell 51, and the wind carries the heat generated by the charging power supply 53, the controller 54 and the wireless communication module 55 and the ambient heat and is discharged from the opening of the chassis shell 51 to achieve wind heat dissipation.

[0034] In the embodiment, a mesh plate 52 is fixedly installed in the opening of the chassis shell 51, and the shielding of the opening can better protect the internal components of the chassis shell 51 without affecting the discharge of hot air.

[0035] In the embodiment, the lower end of the first reduction motor 21 is fixedly equipped with a moving seat 1, which includes: The bottom plate 11 has shock-absorbing universal wheels 12 fixedly mounted at the four corners of the bottom surface; The side wall of the bottom plate 11 is fixedly equipped with a fire baffle 13; The upper surface of the bottom plate 11 is provided with lifting support structures 7 on both the front and rear sides, and the lower ends of the lifting support structures 7 are against the ground after being extended.

[0036] Specifically in this embodiment, the device improves mobility through the support of the mobile base 1, making it easier to move to the fire source; the fire baffle 13 is installed on the side wall of the bottom plate 11 away from the opening of the chassis shell 51, facing the fire source to block heat; Furthermore, when the fire source is not extinguished and spreads to the device, the fire baffle 13 can be used to temporarily block the fire, providing time for the device to evacuate the fire source; More specifically, the four shock-absorbing universal wheels 12 provided on the device have a shock-absorbing effect, so that the device can be transferred more smoothly in the field environment; the lifting support structure 7 is used to support the ground after the position is placed to improve the placement stability of the device.

[0037] Specifically, the main body of the fire baffle 13 is a flame retardant plate 131, and a high temperature resistant ceramic coating 132 is arranged on the side of the flame retardant plate 131 close to the fire source, and the withstanding temperature thereof is ≥1200°C. The flame retardant plate 131 also has a certain flame retardant effect; The main body of the shock-absorbing universal wheel 12 is a universal wheel main body 121, a bearing seat 122 is fixedly mounted in the middle of the top surface thereof, and a shock absorber 123 is fixedly mounted on the inner ring surface of the bearing seat 122, and the upper end of the shock absorber 123 is fixed to the bottom surface of the base plate 11 by a flange and bolts. In the embodiment, the lifting support structure 7 includes: The electric push rod 71 is fixedly mounted on the upper surface of the bottom plate 11, and the telescopic lower end of the electric push rod 71 penetrates the bottom plate 11 and is fixedly mounted with a support plate 72; The support plate 72 includes a plate body 721 , a plug plate 722 is evenly fixedly mounted on the bottom surface of the plate body 721 , and a tip is formed at the lower end of the plate body 721 .

[0038] Specifically in this embodiment, the electric push rod 71 is electrically connected to the charging power source 53 of the chassis 5, and the electric push rod 71 extends to drive the support plate 72 to move downward and abut against the ground; Furthermore, the insert plate 722 on the bottom surface of the plate body 721 of the support plate 72 extends into the ground, thereby improving the stability of the support for the device.

[0039] The second embodiment is different from the first embodiment in that: The booster head 4 includes: The second gun tube 41a has a second internal thread 42a formed on the inner wall of one end thereof, and the second internal thread 42a is screwed to the outer wall of the output end of the fire monitor body 3; An atomizing nozzle 43a is screwed onto the outer wall of the other end of the second barrel 41a.

[0040] Specifically in this embodiment, the water flow supplied from the second gun tube 41a is dispersed and sprayed out to form an atomization effect under the action of the atomizing nozzle 43a, thereby increasing the spraying area and being used to cool down the fire scene to prevent the fire from spreading; Furthermore, the second gun barrel 41a is connected to the external thread provided on the outer wall of the output end of the fire cannon body 3 through the second internal thread 42a, so as to facilitate the disassembly and replacement of other types of booster gun heads 4.

[0042] Specifically in this embodiment, after the water flows into the nozzle housing 431, it is initially dispersed by the mesh tube 433, and then sprayed out through the spray gap between the side wall of the circular plate 432 and the inner wall of the output port of the nozzle housing 431. After the water flows out, it spreads to form an atomization effect.

[0043] 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.
