Most of the existing fire trucks use water as the fire extinguishing agent, or add foam and other fire extinguishing agents on the basis of water to extinguish fires. Obviously, these are not suitable for these special fires. There are also some fire trucks that use dry powder, carbon dioxide and other fire extinguishing agents. Nitrogen fire extinguishing is mainly applied to the emergency disposal of fire accidents in petrochemical production devices, fixed roof storage tanks, inner floating roof storage tanks, road transportation of tank trucks, oil pipelines, ship engine rooms, computer rooms, communication equipment, substations, etc.

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0040] Refer to Figures 1-9 , an intelligent pressure-regulating gas fire truck, including a chassis 1 and a pipeline mechanism 6; the pipeline mechanism 6 is communicated with a control mechanism 4, a nitrogen cylinder group 5, a nitrogen booster 3, an air compressor 2, a membrane nitrogen generation mechanism 8 and a pressure-resistant pipeline 7; the pipeline mechanism 6 is communicated with a plurality of switching mechanisms 63 through a connecting pipe 62 fixedly connected by a shunt pipe 61, and the switching mechanism 63 drives a guide component 64 to move along a pressure dividing component 65 through a control component 67, so that the guide component 64 switches between the high-pressure and low-pressure channels of the pressure dividing component 65; the control component 67 manually drives the guide component 64 to switch with the pressure dividing component 65 through the control component 67;

[0041] Specifically, the chassis 1 is ignited and started to maintain the parking state, the additional power supply and additional air source switch are turned on, and the power take-off is in the engaged state; 62-way connecting pipe: A pressure-resistant pipe, a mobile pressure regulating device, and a special nitrogen release device are connected to the required nitrogen output port. All these pipeline accessories are connected by quick connectors, which is efficient and convenient to operate; after the pipeline connection is completed and the release device is placed at the disposal point, the PLC intelligent control mechanism 4 turns on the nitrogen output mode by operating the touch screen 42. At this time, the power take-off drive shaft of the chassis 1 drives the air compressor 2 to start running. At this time, the air is compressed and enters the membrane nitrogen production device, and substances such as oxygen and water are separated, and high-purity nitrogen with an output pressure of about 1 Mpa is output; at this time, the corresponding outlet pressure is adjusted, and the nitrogen will reach the hazardous chemical disposal site through the pipeline; the pressure at the outlet is manually adjusted by the switching mechanism 63 in the pipeline mechanism 6. By manually driving the position between the guiding component 64 and the pressure dividing component 65 in the switching mechanism 63 through the control component 67, one of the notches in the high-pressure and low-pressure areas of the pressure dividing component 65 is communicated with the guiding mechanism, so that the gas pressure output from the external port 69 fixedly connected to the bottom end of the switching mechanism 63 can be manually set according to the demand, improving the flexibility during the use of this device and reducing the cumbersome phenomenon caused by switching the pressure in the pipeline;

[0042] The pressure dividing component 65 includes a fixed sleeve 651, a built-in pipe 652 is fixedly connected inside the fixed sleeve 651, a low-pressure notch 653 is opened at the top end of the built-in pipe 652, and a high-pressure notch 654 is opened at the bottom end of the built-in pipe 652; a throttling component 66 is provided at one end of the built-in pipe 652 close to the low-pressure notch 653, and the throttling component 66 is adapted to the low-pressure notch 653, and a branch pipe 656 is fixedly connected to the bottom end of the built-in pipe 652;

[0043] Specifically, the fixed sleeve 651 in the pressure dividing component 65 is in a cylindrical structure, the built-in pipe 652 fixedly connected inside the fixed sleeve 651 is in a cylindrical structure, symmetric and inclined low-pressure notches 653 are opened at the top end position of the built-in pipe 652, and high-pressure notches 654 are arranged in an array at the bottom end position of the built-in pipe 652. The low-pressure notch 653 is adapted to the throttling component 66 at an inclined angle, so that during the process of the gas passing through the throttling component 66 in the low-pressure notch 653, the throttling component 66 intermittently blocks the low-pressure notch 653, so that the gas is depressurized. When the gas enters the built-in pipe 652 from the high-pressure notch 654, it remains in the high-pressure gas state without the intervention of the throttling component 66. This device has a simple structure and is flexible to use, and is worthy of wide promotion;

[0044] The guiding component 64 includes a fixing ring 641, and the fixing ring 641 is fixed on the inner wall of the switching mechanism 63. A fixing sleeve 651 is fixedly connected inside the fixing ring 641. The fixing ring 641 is provided with intake holes 644 in an array; a bladder ring 642 is fixedly connected to the bottom end of the fixing ring 641. One end of the bladder ring 642 away from the fixing ring 641 is fixedly connected to a movable ring 643, and the movable ring 643 is arranged in the cavity formed by the fixing sleeve 651 and the built-in pipe 652. A guiding hole 645 is formed in the movable ring 643; a support spring 68 is fixedly connected to the top end of the movable ring 643. One end of the support spring 68 away from the movable ring 643 is fixedly connected to the fixing sleeve 651 and is sleeved outside the built-in pipe 652;

[0045] Specifically, in the guiding component 64, the fixing ring 641 is fixed to the movable ring through the bladder ring 642. The bladder ring 642 is turned inwards, so that the plane cross-sectional view is in a U-shaped structure. The intake holes 644 formed in the fixing ring 641 communicate with the guiding holes 645 formed in the movable ring 643. So that during the position switching of the movable ring 643 along the built-in pipe 652, the bladder ring 642 can move synchronously, realizing that the gas is not affected by the movement of the movable ring 643 in the bladder ring 642, guiding the gas, and improving the flexibility of gas guiding;

[0046] The throttling component 66 includes a connecting column 661, and the connecting column 661 is fixed on the fixing sleeve 651. A rotating shaft seat 662 is arranged at the bottom end of the connecting column 661. A fixing disk 663 is fixedly connected to the bottom end of the rotating shaft seat 662; A fan blade 664 is fixedly connected to the bottom end of the fixing disk 663 in an array. A throttling block 665 is arranged between the fan blades 664, and the throttling block 665 is distributed in a triangular structure on the fixing disk 663; One end of the throttling block 665 away from the fixing disk 663 is fixedly connected to a limiting ring 666;

[0047] Specifically, in the throttling component 66, the rotating shaft seat 662 connected by the connecting column 661 is fixedly connected to the fixing disk 663, so that the fixing disk 663 can rotate along the axis of the support column. When the gas penetrates into the fan blades 664 fixedly connected to the fixing disk 663, the flow rate of the gas generates a thrust on the fan blades 664. Then the fan blades 664 drive the fixing disk 663 to rotate along the axis of the support column. The throttling blocks 665 distributed in a triangular structure on the fixing disk 663 indirectly close the low-pressure notch 653 during the rotation process, so that the throttling component 66 reduces the pressure of the gas penetrating into the low-pressure notch 653, so as to realize the switching of the switching mechanism 63 between high pressure and low pressure, improve the flexibility of the use of this device, and avoid the limitations generated when using a single high-pressure pipe and a single low-pressure pipe;

[0048] The control component 67 includes a lock sleeve 671, and the lock sleeve 671 is fixed on the inner wall of the switching mechanism 63. Lock grooves 672 are symmetrically formed at both ends of the lock sleeve 671. A lock rod 673 penetrates through the lock sleeve 671. One end of the lock rod 673 is fixedly connected to a lock block 675, and the lock block 675 is adapted to the lock groove 672. The top end of the lock rod 673 is fixedly connected to a handle 674. The control mechanism 4 includes a chassis 41. One end of the chassis 41 is fixedly connected to a touch screen 42, and control keys 43 are provided at the bottom end of the touch screen 42.

[0049] Specifically, the lock sleeve 671 in the control component 67 is of a symmetrical structure. Pulling the lock rod 673 drives the lock block 675 to move directionally, so that the lock block 675 is locked in the lock grooves 672 formed at both ends of the lock sleeve 671. The connecting rod 677 fixedly connected to the bottom end of the lock rod 673 through a connecting arm 676 drives the movable ring 643 to move along the inner pipe 652, realizing manual adjustment of the position of the movable ring 643, and switching between high pressure and low pressure according to requirements, reducing the limitations of the device during use.

[0050] Working principle: The chassis 1 is ignited and started to maintain the parking state. The additional power supply and additional air source switches are turned on, and the power take-off is in the engaged state. Connecting pipe 62 path: A pressure-resistant pipe, a mobile pressure regulating device, and a special nitrogen release device are connected to the required nitrogen output port. All these pipeline accessories are connected by quick-connect joints, and the operation is efficient and convenient. After the pipelines are connected and the release device is placed at the disposal point, the PLC intelligent control mechanism 4 starts the nitrogen output mode by operating the touch screen 42. At this time, the power take-off drive shaft of the chassis 1 drives the air compressor 2 to start running. At this time, the air is compressed and then enters the membrane nitrogen production device, and substances such as oxygen and water are separated, and high-purity nitrogen with an output pressure of about 1 Mpa is output. At this time, the corresponding outlet pressure is adjusted, and the nitrogen will reach the hazardous chemical disposal site through the pipeline. Among them, the outlet pressure is manually adjusted by the switching mechanism 63 in the pipeline mechanism 6. The position between the guiding component 64 and the pressure dividing component 65 in the switching mechanism 63 is manually driven by the control component 67, so that one of the notches in the high-pressure and low-pressure areas in the pressure dividing component 65 is communicated with the guiding mechanism, so that the gas pressure output from the external port 69 fixedly connected to the bottom end of the switching mechanism 63 is manually set according to requirements, improving the flexibility of the device during use and reducing the cumbersome phenomenon caused by switching the pressure in the pipeline.
