[0002] Fire monitors are widely used in the field of fire fighting. During the use of existing fire monitors, the fire monitors will vibrate due to the huge water pressure they will withstand during use, which will cause the connection between the fire monitor and the ground water inlet pipe to loosen, resulting in leakage between the fire monitor and the water inlet pipe, affecting the use of the fire monitor and even affecting the fire situation, causing huge losses. Summary of the invention

[0003] Therefore, in order to solve the above problems, the present invention proposes a fire cannon with good shock absorption effect and intelligent Internet of Things function.

[0004] To achieve the above-mentioned purpose, the technical solution of the present invention is to provide a fire monitor with intelligent Internet of Things function, including a connecting flange, a water inlet barrel arranged on the connecting flange, a first barrel rotatably arranged on the water inlet barrel, a horizontal rotation mechanism arranged on the water inlet barrel for driving the first barrel to rotate, a second barrel rotatably arranged on the first barrel, an elevation rotation mechanism arranged on the first barrel for driving the second barrel to rotate, and an adjusting gun head arranged on the second barrel for adjusting the state of the spray water column. The first barrel is also provided with a control device for controlling the horizontal rotation mechanism, the horizontal rotation mechanism and the adjusting gun head. A shock absorbing device for reducing the vibration of the fire monitor when water is discharged is also provided between the water inlet barrel and the ground.

[0007] A further improvement is that the buffer device includes: a spring arranged in the sliding groove and connected to the bottom of the gear row, and an elastic layer respectively arranged between the upper and lower sides of the sliding groove and between the upper and lower sides of the two baffles.

[0008] A further improvement is that at least two guide holes are provided at the bottom of the tooth row, a guide column matching the size of the guide holes is provided on the sliding groove, and the spring is sleeved on the guide column.

[0009] A further improvement is that the horizontal rotating mechanism includes: a first reduction motor arranged on the water inlet barrel, a first worm gear arranged on the first barrel, and a first worm gear for driving the first worm gear to rotate is arranged on the rotating rod of the first reduction motor.

[0014] The advantages and beneficial effects of the present invention are:

[0015] The structure is simple and is provided with a shock absorbing device. Through the meshing of gears and multiple tooth rows in opposite directions, when the fire monitor vibrates forward, one tooth row provides a force to block its forward movement, and a tooth row in the opposite direction provides a force to pull it backward, thereby reducing the radial force generated by the vibration to a certain extent, and when a certain degree of circumferential rotation occurs, multiple tooth rows will work together with the gears to prevent it from rotating under the drive of the fire monitor, thereby reducing the circumferential force generated by the vibration to a certain extent. When axial vibration occurs, the force will be directed to the tooth row opened and closed in the block and the sliding groove, and then the force will be transmitted to the elastic layer, thereby reducing the axial force generated by the vibration to a certain extent, improving the connection stability of the fire monitor and the ground water pipe, and improving the service life.

The first barrel 2 is also provided with a control device for controlling the horizontal swivel mechanism, the horizontal swivel mechanism and the adjusting gun head. A shock absorbing device for reducing the vibration of the fire monitor when water is discharged is also provided between the water inlet barrel 1 and the ground.

[0023] In order to mitigate the vibration forces in multiple directions, the shock absorbing device includes: a square supporting shell 4 arranged on the ground and surrounding the water inlet barrel 1, a gear 5 fixedly arranged on the water inlet barrel 1, and at least four gear rows 6 arranged on the square supporting shell 4 through a sliding device, located between the square supporting shell 4 and the gear 5 and meshing with the gear 5. The gear row 6 is also provided with a buffer device for reducing vibration.

[0024] In order to allow the tooth row 6 to slide between the gear 5 and the square support shell 4, the sliding device includes: a sliding groove 7 opened on the square support shell 4 and matching the size of the tooth row 6 for sliding of the tooth row 6, and two baffles 8 arranged on the water inlet barrel 1 at the upper and lower sides of the gear 5 and with a spacing matching the size of the tooth row 6.

[0025] In order to mitigate the vibration force, the buffer device includes: a spring 9 arranged in the sliding groove 7 and connected to the bottom of the tooth row 6, and an elastic layer (not shown in the figure) respectively arranged between the upper and lower sides of the sliding groove 7 and between the upper and lower sides of the two baffles 8, and the elastic layer is a rubber layer.

[0026] In order to enhance the stability of the shock absorbing device, at least two guide holes (not shown in the figure) are provided at the bottom of the gear row 6 , and a guide column 12 matching the size of the guide holes is provided on the sliding groove 7 , and the spring 9 is sleeved on the guide column 12 .

[0027] In order to facilitate the control of the horizontal angle of the fire monitor, the horizontal rotation mechanism includes: a first reduction motor 13 arranged on the water inlet barrel 1, and a first worm gear (not shown in the figure) arranged on the first barrel 2. The rotating rod of the first reduction motor 13 is provided with a first worm (not shown in the figure) for driving the first worm gear to rotate.

[0028] In order to facilitate the control of the elevation angle of the fire monitor, the elevation and depression rotation mechanism includes: a second reduction motor 14 arranged on the first gun barrel 2, and a second worm gear (not shown in the figure) arranged on the second gun barrel 3. The rotating rod of the second reduction motor 14 is provided with a second worm (not shown in the figure) for driving the second worm gear to rotate.

[0029] In order to facilitate the control of the water outlet state of the fire monitor, the adjusting gun head includes: a water outlet block 15 arranged at the water outlet end of the second gun barrel 3, and an adjusting tube 16 which can slide back and forth through a telescopic device and is arranged on the second gun barrel 3 for cooperating with the water outlet block 15 to adjust the water outlet state. The telescopic device includes: a fixing plate 17 arranged on the second gun barrel 3, and a telescopic motor 18 arranged on the fixing plate 17. The telescopic rod of the telescopic motor 18 is connected to the adjusting tube 16 for driving the adjusting tube 16 to slide back and forth.

[0030] In order to facilitate the control of the fire cannon, the control device includes: a junction box 20 arranged on the first gun barrel 2, the junction box 20 is electrically connected to the first reduction motor 13, the second reduction motor 14 and the telescopic motor 18, and the junction box 20 is also electrically connected to a control cabinet (not shown in the figure) for the user to control the fire cannon. Detection components are installed in the control cabinet to monitor the electronic components, voltage and equipment operation status in the cabinet. If the fire cannon fails, it will alarm in time and notify the management personnel. The management personnel can operate and control it remotely through PC, mobile phone applets, etc., and it also has a locking alarm function.

[0031] Working principle: When in use, the first reduction motor 13 is controlled by the control cabinet to drive the first gun barrel 2 to rotate horizontally, so that the fire cannon is directed toward the fire source. Then the second reduction motor 14 rotates to drive the second gun barrel 3 to rotate so that the second gun barrel 3 swings up and down, so that the fire cannon is aimed at the fire source. At this time, the telescopic motor 18 is controlled to control the regulating tube 16 to slide upward or downward. When sliding downward, the fluid flows out directly without passing through the regulating tube 16, and is scattered, thereby spraying a rain curtain. When sliding upward, the fluid first gathers in the regulating tube 16 and then sprays out to form a water column.

[0032] When the fluid is sprayed out, it will inevitably cause the fire monitor to vibrate. At this time, when the fire monitor drives the gear 5 to rotate slightly, the circumferential force of the gear 5 and the magnetic row is decomposed and converted into a force directly applied to the spring 9, thereby achieving the resolution of the circumferential vibration force and reducing the vibration. When vibrating forward, backward, left and right, since the gear 5 and the tooth row 6 are meshed and stuck, when the fire monitor vibrates forward, it will drive the tooth row 6 to vibrate forward together. At this time, one tooth row 6 will compress the spring 9, and the other tooth row 6 will stretch the spring 9, thereby reducing the vibration force. When axial vibration occurs, the force will be transmitted to the elastic layer and the protective block connected to the ground through the tooth row 6, thereby reducing the vibration.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
