Description

Technical Field

[0001] The invention relates to the technical field of turbofan gun fire extinguishing devices, and in particular to a fine water mist turbofan gun fire extinguishing device. Background Art

[0002] The fine water mist turbofan cannon is a highly efficient fire-fighting equipment. It atomizes water through a large turbofan device, achieving efficient cooling and fire-fighting with a huge heat exchange area and a three-dimensional wrapping range. Compared with traditional fire water guns and fire cannons, this effectively increases the fire-fighting area and improves the fire-fighting efficiency. Compared with traditional fire water cannons, it consumes less water and has better directionality than traditional fine water mist fire-fighting systems. It can cover the fire area more effectively. For oil fires, foam fire extinguishing agents can be added to the water to further improve the fire-fighting performance.

[0003] In a turbofan gun device with application number CN202410701784.4, a driving mechanism is provided, which is drivingly connected to the end of the light rod section away from the spiral section; a water storage tank is connected to the first inlet through a first pipeline; a fire extinguishing agent tank is connected to the second inlet through a second pipeline; and a turbofan gun is connected to the outlet. The technical solution of this application effectively solves the problem of poor mixing effect of the foam proportioning mixer used in the turbofan gun in the related art.

[0004] In actual use, the mixed fire extinguishing liquid is pressurized by a water pump and a foam pump into a foam proportion mixing device and mixed according to a set ratio, and then output to a fine water mist turbofan gun fire extinguishing device, and then smaller fine water mist droplets are generated through the nozzle, and pushed out over a long distance under the wind transmission of the turbofan to achieve long-distance fire extinguishing. However, in actual use, it is necessary to adjust the output distance of the turbofan gun in real time according to the fire, and the elevation angle can also be adjusted to extinguish fires at different heights. However, when the turbofan gun is at an elevation angle, the turbofan gun needs to overcome the gravity of the mixed fire extinguishing agent to do work. At this time, the distance that the turbofan at the same power pushes the fire extinguishing agent will be reduced, and there will be a risk of ineffective fire extinguishing. At the same time, when the turbofan gun is in a downward state, the fire extinguishing agent water mist will accelerate the spraying of water mist under the action of gravity and the push of the turbofan gun, so that the water mist flow rate increases. At this time, it is easy to drive the rapid flow of air at the fire location, increase the spread area of ​​the fire, and easily bring negative effects to the fire extinguishing operation.

[0005] Therefore, the present invention solves the above-mentioned problem through a fine water mist turbofan cannon fire extinguishing device. Summary of the invention

[0022] Technical effects and advantages of the present invention:

[0023] 1. When the turbofan of the present invention rotates, the air will flow out through the direct current channel and the vortex channel. The amount of gas flowing through the direct current channel is greater than the amount of gas in the vortex channel. The six groups of guide units arranged in the vortex channel can slow down the flow of the gas and have a turbulent effect, thereby forming a vortex airflow in the vortex channel. In this way, the air can be directly pushed out after passing through the direct current channel to form an outer airflow protection ring, while the gas in the inner tube of the turbofan gun will first pass through the first vortex channel, and form a preliminary vortex after the guide effect of the first vortex channel, and then be introduced into the second vortex channel, which can achieve the enhancement of the vortex. Under the blowing of the vortex airflow, the water droplets are decomposed into finer droplets, and after the vortex airflow is blown out from the diffusion channel, it can quickly wrap the droplets atomized by the atomization ring, avoiding a significant shortening of the blowing distance due to the lack of pushing power after the droplets are atomized. At the same time, under the push of the outer airflow protection ring, the vortex airflow and the atomized droplets are wrapped and pushed forward, thereby increasing the pushing distance of the turbofan gun.

[0024] 2. When the turbofan is working, the present invention facilitates the conversion from forming a vortex to increasing the amount of vortex gas when the gas flows in the vortex channel. This not only ensures the vortex shape of the gas, but also ensures the amount of gas in the vortex, avoiding the situation where there is a vortex shape but the gas amount is insufficient and the droplets cannot be wrapped. It can also avoid the situation where the vortex is small but the gas amount is sufficient, thereby reducing the pushing distance of the droplets. The distance between the guide units is adaptively adjusted according to the gas impact force when the turbofan rotates, so as to achieve self-balance of the vortex and the gas amount, and ensure the pushing distance of the turbofan gun and the wrapping and carrying capacity of the droplets.

[0025] 3. The present invention can adjust the output state of the turbofan gun in real time according to the pitch angle of the turbofan gun, and increase the adaptability to the fire conditions by being in different output states under high and low fire conditions.

[0042] See also Figure 4 and Figure 5 The turbofan 6 includes a fixing ring 61 fixed at the rear end of the turbofan gun outer tube 5. The fixing ring 61, the turbofan gun outer tube 5, the turbofan gun inner tube 12, and the mounting tube 14 are fixedly connected by a reinforcing rod 62 to ensure the installation stability of the turbofan gun outer tube 5, the turbofan gun inner tube 12, and the mounting tube 14.

[0043] See also Figure 1-Figure 4 ,,The supporting assembly includes a base 1. The top outer side of the base 1 is rollingly equipped with a shell 2. The left and right side walls of the shell 2 are integrally formed with a fixing seat 3. A bracket 4 is hingedly assembled between the two sets of fixing seats 3 through a rotating shaft. The turbofan gun outer tube 5 is fixedly welded on the bracket 4. The left and right side walls of the turbofan gun outer tube 5 are fixedly installed with lighting lamps 18.

It can realize early detection of fire, fast response speed, can detect various types of smoke, and can effectively avoid the influence of airflow movement. The lighting lamp 18 provides lighting.

[0044] See also Figure 3A driving motor 9 is fixed in the middle of the top of the base 1, and a support 10 is integrally formed on the top of the inner cavity of the shell 2. The output end of the driving motor 9 is fixed at the bottom of the support 10, and a delivery pipeline 8 is suspended in the support 10. A liquid inlet pipe 11 is fixedly assembled on the base 1, and the other end of the liquid inlet pipe 11 passes through the support 10 and is connected to the delivery pipeline 8, and a retreat channel matching the liquid inlet pipe 11 is opened on the outer wall of the support 10, and the range of the retreat channel is 180 degrees. When the driving motor 9 is working, it drives the support 10 to rotate synchronously with the shell 2, and then the turbofan gun can be rotated in the horizontal direction, and the retreat channel ensures that the liquid inlet pipe 11 will not interfere with the support 10.

[0045] See also Figure 2 A shear plate is fixed on the rear side wall of the bracket 4, and a hinge seat is fixed on the top of the shell 2. The top end of the electric telescopic rod 7 is hingedly assembled on the shear plate through a pin shaft, and the bottom end is hingedly assembled on the hinge seat through a pin shaft. When the electric telescopic rod 7 is extended, it can drive the turbofan gun on the bracket 4 to rotate around the rotating shaft on the fixed seat 3, and then drive the turbofan gun to be adjusted downward. When the electric telescopic rod 7 is retracted, it can drive the turbofan gun to be raised, thereby realizing the adjustment of the pitch angle of the turbofan gun.

[0046] See also Figure 2 and Figure 7 The delivery pipeline 8 includes a main bearing seat 30 fixedly assembled with the liquid inlet pipe 11, and a tee 31 is rotatably assembled on the top of the main bearing seat 30. Auxiliary bearing seats 32 are installed at the other two ends of the tee 31. One group of auxiliary bearing seats 32 is rotatably assembled with a first liquid guide tube 33, and the other end of the first liquid guide tube 33 is connected to the atomizing ring 16. Another group of auxiliary bearing seats 32 is rotatably assembled with a second liquid guide tube 34, and the other end of the second liquid guide tube 34 is connected to the central nozzle 15.

[0047] A first solenoid valve is fixedly mounted on the first liquid conduit 33, and a second solenoid valve is fixedly mounted on the second liquid conduit 34, so that liquid can be transmitted in different directions through the first liquid conduit 33 and the second liquid conduit 34. When the atomizing ring 16 is connected, the pushing work of the turbofan gun can be realized. When the central nozzle 15 is connected, the central nozzle 15 realizes direct blowing of the fire extinguishing agent, thereby realizing fire extinguishing operations in different modes.

[0048] When the driving motor 9 drives the shell 2 and the turbofan gun to rotate synchronously, the tee 31 can rotate on the main bearing seat 30 to ensure that there is no interference when the turbofan gun rotates. Similarly, when the electric telescopic rod 7 drives the turbofan gun to achieve pitch adjustment, the first liquid guide tube 33 and the second liquid guide tube 34 will rotate relative to the auxiliary bearing seat 32 to ensure the smooth pitch adjustment of the turbofan gun.

[0049] See also Figure 5 and Figure 6The inner wall of the turbofan gun inner tube 12 is evenly provided with six groups of guide units along the length direction, a direct current channel 20 is formed between the turbofan gun inner tube 12 and the turbofan gun outer tube 5, the mounting tube 14 is a two-section fixed column, the diameter of the rear section is larger than the diameter of the front section, and a first vortex channel 21 is formed between the rear section and the turbofan gun inner tube 12, a second vortex channel 22 is formed between the front section and the turbofan gun inner tube 12, and a diffusion channel 23 is formed between the front section and the guide cover 13.

[0050] When the turbofan 6 rotates, the air will flow out through the direct current channel 20 and the vortex channel. Since the width of the direct current channel 20 is greater than the width of the vortex channel, the amount of gas flowing through the direct current channel 20 is greater than the amount of gas in the vortex channel, and the six groups of guide units arranged in the vortex channel can slow down the flow of the gas and have a turbulent effect, thereby forming a vortex-shaped airflow in the vortex channel. In this way, the air can be directly pushed out after passing through the direct current channel 20 to form an outer airflow protection ring, and the gas in the turbofan gun inner tube 12 will first pass through the first vortex channel 21, and after the guide effect of the first vortex channel 21, a preliminary The vortex is then introduced into the second vortex channel 22, which can enhance the vortex and increase the gas volume of the vortex airflow in the second vortex channel 22, so as to achieve the effect of gas gathering and pressurization, and then it is ejected through the diffusion channel 23. Under the blowing of the vortex airflow, the water droplets are decomposed into smaller droplets. After the vortex airflow is blown out from the diffusion channel 23, it can quickly wrap the droplets atomized by the atomization ring 16, avoiding a significant shortening of the blowing distance due to the lack of pushing power after the droplets are atomized. At the same time, under the push of the outer airflow protection ring, the vortex airflow and the atomized droplets are wrapped and pushed forward, thereby increasing the pushing distance of the turbofan gun.

[0051] See also Figure 5 and Figure 8 The frontmost group of guide units is fixed on the inner wall of the turbofan gun inner tube 12 and is set as a fixed guide unit. The other five groups of guide units are slidably assembled on the inner wall of the turbofan gun inner tube 12 along the same direction and are set as movable guide units. It is convenient for each group of movable units to slide on the inner wall of the turbofan gun inner tube 12 to adjust the gap between the guide units, and the amount of vortex gas between the guide units in the vortex channel can be adjusted, so as to adjust the flow rate of the vortex airflow, that is, the distance between the guide units is reduced, and the flow rate of the vortex airflow is increased, otherwise it is the opposite.

[0052] See also Figure 5 and Figure 6Each group of guide units includes three groups of guide plates 24 evenly arranged along the circumferential direction of the turbofan gun inner tube 12, and the curvature of each group of guide plates 24 is the same. The arrangement of the three groups of guide plates 24 can slow down the flow rate of the gas introduced from the turbofan 6 into the vortex channel, and has a blocking effect on the gas, and then a vortex is formed under the turbulent effect of multiple groups of guide plates 24, and the closer the distance between the guide plates 24, the greater the blocking effect on the gas under the cooperation of multiple groups of guide plates 24, and the flow rate of the vortex airflow formed in the vortex channel will increase, and each group of guide plates 24 is 1 / 4 of the circumference of the turbofan gun inner tube 12, so that there is an air circulation channel between the guide plates 24 in the circumferential direction, which is convenient for the introduction of gas and can increase the amount of gas introduced into the vortex channel when the turbofan 6 is working, so that the shooting speed of the gas ejected from the vortex channel can be increased.

[0053] A return spring 29 is fixedly connected between two adjacent groups of guide units, and a slideway 25 is provided on the inner side wall of the turbofan gun inner tube 12, and the return spring 29 is embedded in the slideway 25. In this way, when the turbofan 6 is working, the gas introduced into the vortex channel will generate a gas squeezing pressure on the last group of guide units, so that the last group of guide units will generate a squeezing pressure on the last group of return springs 29, so that the distance between the last group of guide units and the second to last group of guide units is reduced. Similarly, after the second to last group of guide units are squeezed, a squeezing pressure will be generated on the second to last group of return springs 29, and then a squeezing pressure will be generated on the third to last group of guide units. By analogy, all six groups of return springs 29 will undergo compression deformation, and the deformation amount decreases from the back to the front. Small, so that the distance between the guide units gradually increases from back to front, so that the gas flow rate from the vortex channel will also gradually increase, and when the turbofan 6 is working, it is convenient for the gas to flow in the vortex channel, and the conversion from forming a vortex to increasing the vortex gas volume can be ensured. This not only ensures the vortex shape of the gas, but also ensures the gas volume of the vortex, avoiding the situation where there is a vortex shape but the gas volume is insufficient and the droplets cannot be wrapped. It can also avoid the situation where the vortex is small but the gas volume is sufficient, which reduces the pushing distance of the droplets. The distance between the guide units is adaptively adjusted according to the gas impact force when the turbofan 6 rotates, so as to achieve self-balance of the vortex and the gas volume, and ensure the pushing distance of the turbofan gun and the wrapping and carrying capacity of the droplets.

[0054] See also Figure 6 and Figure 8 A slide 26 slidably assembled inside the slide 25 is fixed on the guide plate 24 in each group of active guide units. Electromagnetic plates 27 are fixed on the rear side walls of the first four groups of slides 26 and the front side walls of the slide 25. A magnet sheet 28 is fixed on the front side wall of each group of slides 26. Both ends of the return spring 29 are fixed between the electromagnet plate 27 and another group of magnet sheets 28.

[0055] In actual use, when the electric telescopic rod 7 is extended to drive the turbofan gun to lower the pitch angle, it indicates that the turbofan gun is extinguishing the fire in the lower terrain. At this time, the controller synchronously controls the five groups of electromagnet plates 27 to be energized synchronously (introducing forward current), which can generate a magnetic repulsion force on the magnet sheet 28. The slide seat 26 is an insulating shielding seat, so there is no magnetic force between the electromagnet plate 27 and the magnet sheet 28 mounted on the same slide seat 26. In this way, the electromagnet plate 27 only has a magnetic repulsion force on the relative magnet sheet 28. This can push the slide 26 to overcome the pulling force of the return spring 29 in the slide 25 and move backward, so that the horizontal distance between the two adjacent groups of guide plates 24 will increase, so that the gas flow space between the two adjacent groups of guide plates 24 in the horizontal direction will increase, and the eddy speed generated by the gas will decrease, which can increase the uniformity of the gas wrapping of the droplets and slow down the flow speed of the eddy current, so as to ensure the coverage area of ​​the low-lying fire when the turbofan gun is working, and at the same time reduce the impact force on the fire, improve the quality of fire extinguishing, and eliminate hidden dangers.

[0056] On the contrary, when the electric telescopic rod 7 is retracted to drive the turbofan gun to adjust the pitch angle upward, it indicates that the turbofan gun is performing a fire extinguishing operation on a fire at a higher terrain. At this time, the controller synchronously controls the five groups of electromagnet plates 27 to be energized synchronously (introducing reverse current), which can generate a magnetic attraction to the magnet sheet 28, and the slide 26 is an insulating shielding seat, so there is no magnetic force between the electromagnet plates 27 and the magnet sheets 28 mounted on the same slide 26, so that the electromagnet plates 27 only have a magnetic attraction to the relative magnet sheets 28, so that the slide 26 can overcome the rebound force of the return spring 29 in the slide 25 and move forward, so that the horizontal distance between the two adjacent groups of guide plates 24 will be reduced, so that the gas flow space between the two adjacent groups of guide plates 24 in the horizontal direction is reduced, so that the eddy current speed generated by the gas is increased, so that the gas carrying capacity of the droplets can be increased, so that the pushing distance of the eddy current when the turbofan gun is working is increased, so as to achieve the adaptation of the turbofan gun to the high-altitude fire when working, and ensure that the fire can be extinguished.
