[0002] In the processing production lines of petrochemical products, such as heavy aromatics production, naphtha production, storage and transportation of raw materials, intermediates and products, high temperature and high pressure conditions are often required, which requires strict control of fire protection issues around reaction vessels, near pipelines, and near material storage and loading and unloading areas. Foam fire-fighting facilities are usually required to be deployed in high-risk areas.

[0003] Most of the existing fire fighting facilities use fixed gun heads or tow gun heads. No matter which style, the gun heads need to be operated manually, which requires personnel to be on site in emergency situations. However, in the case of petrochemical production and storage and transportation of petrochemical products, its raw materials, intermediates and products are flammable and explosive, and combustion may be accompanied by the release of toxic and corrosive gases. It also has three-dimensional, large-area and long-term burning, which poses a great risk to the lives of the personnel on site. Utility Model Content

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0019] Example:

[0020] Including the main pipeline 1 installed upright, in many cases the fire-fighting pipeline is laid under the floor. For the unloading area, a metal mesh grating plate 2 is used. In addition to the fire-fighting pipeline, other pipelines are also under the grating plate 2, which is easy to clean and avoid accumulation of water or materials and slippery.

[0021] The bottom of the main pipeline 1 is located below the grid plate 2 and is connected to a fire water supply pipeline, to which a foam proportioning mixer is connected, so that the fire water supply pipeline is a high-pressure water source capable of providing a large amount of foam.

[0022] The top of the main pipeline 1 is exposed above the grid plate 2, and the top of the main pipeline 1 is fixedly connected with an adapter sleeve 3 coaxially sealed and connected thereto through a flange and bolts. The top of the adapter sleeve 3 is provided with a rotating seat 4 coaxially sealed and rotatably connected thereto. The rotating seat 4 is a straight columnar pipe. The bottom end of the rotating seat 4 is inserted into the top of the adapter sleeve 3 and the two are sealed and rotatably connected. The top of the rotating seat 4 is fixedly connected with an upper water pipe coaxially connected thereto through a flange and bolts. The upper water pipe includes a riser 5 located at the bottom, and the top of the riser 5 is connected to Two symmetrically curved water distribution pipes 6, the top of which is connected to a transverse pipe 7, the two transverse pipes 7 are coaxially arranged and extend relatively symmetrically, a swing pipe 8 is arranged between the two transverse pipes 7, the two ends of the swing pipe 8 are respectively connected to the transverse pipe 7 on the same side in a sealed and rotatable manner, so as to realize the concentration of water from the upper water pipe into the swing pipe 8, the swing pipe 8 is a horizontally extending pipe fitting, the middle of the swing pipe 8 is fixed with a pipe joint 10 vertically connected thereto, the pipe joint 10 is connected to a gun head 11, and the gun head 11 can be a common straight barrel gun head 11 in existing fire protection. The extension direction of the articulated seat 9 corresponds to the radial direction of the swing pipe 8, and the relative angle between the articulated seat 9 and the pipe joint 10 is 110 degrees.

[0023] Based on the above-mentioned pipeline connection structure, when the main pipeline 1 is connected to the fire water, the flow route of the fire water is from the bottom fire water supply pipeline - (upward) - main pipeline 1 - (upward) - adapter - (upward) - rotating seat 4 - (upward) - riser 5 of the upper water pipe - (diversion) - water diversion pipe 6 of the upper water pipe - (lateral gathering) - horizontal pipe 7 of the upper water pipe - (convergence) - swing pipe 8 - gun head 11.

[0024] Based on the above structure, the gun head 11 has an operating range of circumferential rotation and up and down swinging, thereby taking into account a wide range of fire extinguishing needs, and has advantages in corresponding three-dimensional fire conditions and multi-point fire conditions.

[0025] A lower mounting platform 12 fixedly welded relative to the adapter seat is provided on the side wall of the adapter seat, and a horizontally extending worm 13 is rotatably mounted on the lower mounting platform 12. A worm wheel 14 meshing with the worm 13 is provided at the bottom of the rotating seat 4. The worm 13 is controlled based on a motor, and the rotation of the worm 13 is used to drive and control the rotation of the rotating seat 4, thereby achieving the control requirements of circumferential injection.

[0026] The side wall of the rotating seat 4 is provided with an upper mounting platform 15 fixedly welded thereto, and the upper mounting platform 15 is provided with a mounting seat 16 on the outer side away from the rotating seat 4, and a swing shaft 17 based on motor control is rotatably mounted on the mounting seat 16, and a screw 18 is fixed on the swing shaft 17, and an articulated seat 9 is also provided on the swing tube 8, and a screw sleeve 19 is hinged on the articulated seat 9, and the screw sleeve 19 is penetrated by the screw 18 and is threadedly matched with the screw 18. Therefore, based on this structure, the gun head 11 can swing up and down and position. This structure indirectly controls the swing through the thread, can take into account both control and locking, and the stop is stable, can resist the reverse force of the water spray, and better support the spray angle of the gun head 11.

[0027] Motors are mounted on the lower mounting platform 12 and the upper mounting platform 15, respectively, and the output shafts of the motors are used to drive the worm 13 and the swing shaft 17. A protective cover can also be set around the rotating seat 4 to cover the transmission structure and the motor inside. The protective cover can be flexibly set and is not shown in the drawings.

[0028] The fire water supply pipelines are all controlled by electronically controlled remote valves, so that the water supply can be remotely opened, the angle and position of the spray can be automatically controlled, and unattended fire-fighting operations can be realized, preventing people from approaching the fire area and ensuring the safety of people to the greatest extent.

[0029] If conditions permit, the linkage between the on-site fire situation and the valve start-up can also be initiated. Signal acquisition can be based on video signal recognition combined with the signal acquisition of the on-site smoke sensor, so as to send control signals to the valve equipment and motor equipment in the control center or cloud platform to achieve automatic response.

[0030] Based on the above device, the operation of the water gun is no longer dependent on manual operation, and the spray angle and spray area of ​​the water gun can be automatically adjusted and controlled, thereby providing a hardware equipment foundation for remote control and precise fire extinguishing.
