Description

Technical Field

[0001] This invention relates to the field of fire protection equipment technology, specifically to a pneumatic energy-saving fire sprinkler system. Background Technology

[0002] Fire monitors are fire extinguishing devices that use water as a medium to extinguish fires over long distances. They consist of three main parts: a water supply system, an execution system, and a control system. They are mainly used in petrochemical enterprises, tank farms, aircraft hangars, warehouses, ports, garages, and other similar locations. They can also be used as vehicle-mounted fire monitors for fire trucks. Types include fixed fire monitors, automatic fire monitors, automatic scanning water jet high-altitude water monitors, automatic scanning water jet fire extinguishing devices, large-space intelligent fire extinguishing devices, fixed manual fire monitors, automatic homing fire monitors, and electrically controlled fire monitors. In existing technologies, the water pressure supplied by conventional water pumps during water cannon spraying is low. The pressure boosting effect of water cannons can be improved by combining air pumps with water pumps. However, when using air pumps, the air entering the air pump contains a large number of impurities, which can directly enter the air pump and block the internal flow channels. This causes the air pump to have a slow airflow rate during subsequent use, ultimately reducing the spray pressure of the water cannon nozzle. To address this issue, we propose a pneumatic energy-saving fire sprinkler device. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, through an air intake filtration mechanism, enables the power supply and control of the air pump via an external power source and controller. During the operation of the air pump, outside air enters the pneumatic turbine assembly through the air intake filtration mechanism and intake valve. During this process, the air passes through multiple rotating blades, which in turn drive the follower shaft to rotate. The follower shaft directly drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate. The second bevel gear drives the first rotating shaft to rotate, which in turn drives the third bevel gear to rotate, which in turn drives the fourth bevel gear to rotate. The fourth bevel gear then drives the second rotating shaft to rotate, which in turn drives the rotating bar and cleaning scraper to clean impurities adhering to the filter screen surface. This process filters impurities in the air entering the intake pipe and simultaneously cleans impurities on the filter screen surface, ensuring the air intake efficiency of the intake pipe and improving the water pump's spraying effect.

[0014] 2. The present invention, through a support mechanism, enables the water pump and the nozzle to generate a reaction force when water spraying is required. At this time, the two symmetrically arranged electric push rods can be simultaneously powered and controlled by an external power supply and an external controller. The output end of the electric push rod drives the triangular support block to move diagonally downward. When the lower end of each triangular support block contacts the ground, the power supply and control of the two symmetrically arranged electric push rods can be stopped, thus improving the stability of the device during the water spraying process.

[0015] 3. This invention, through a workbench, support frame, support plate, air pump, regulating valve, pneumatic turbine assembly, water pump, water tank, water outlet pipe, nozzle, vent pipe, and air inlet valve, enables the air pump, regulating valve, pneumatic turbine assembly, and water pump to be powered by an external power supply and external controller. At this time, the air pump works to draw outside air into the air inlet pipe, and the air then passes through the air inlet valve, regulating valve, pneumatic turbine assembly, and vent pipe to enter the water pump inlet, realizing the pressurization of the water pump for water spraying. At this time, the water pump pumps the water in the water tank out, and the water is directly pressurized and sprayed out from the nozzle. Attached Figure Description

[0019] Please see Figure 1 - Figure 5This invention provides a technical solution: a pneumatic energy-saving fire sprinkler device, comprising a workbench 1, with support frames 2 fixedly installed at each corner of the lower end of the workbench 1, and a support plate 5 fixedly installed between the inner walls of multiple support frames 2. A support mechanism 16 is provided at the middle of the front ends of the two front support frames 2. An air pump 6 is fixedly installed on the right side of the upper middle part of the support plate 5. A regulating valve 7 is fixedly connected to the left side of the air pump 6. A vent pipe 15 is fixedly connected to the end of the regulating valve 7 away from the air pump 6. The vent pipe 15 is bent, and a vent is provided on the rear side of the upper section of the vent pipe 15. A pneumatic turbine assembly 8 has a central shaft 18 fixedly installed on the right end of its output shaft. A water pump 10 is located on the right side of the central shaft 18. The right end of the central shaft 18 is fixedly installed on the left end of the input shaft of the water pump 10. The lower end of the water pump 10 is fixedly installed on the upper end of the workbench 1. A nozzle 14 is fixedly connected to the water outlet port of the water pump 10. A water outlet pipe 13 is fixedly connected to the water inlet port of the water pump 10. A water tank 11 is fixedly connected to the lower rear end of the water outlet pipe 13. An air inlet valve 17 is provided at the air inlet end of the air pump 6. An air inlet filter mechanism 9 is provided at the front end of the air inlet valve 17.

[0020] In this embodiment, the air intake filter mechanism 9 includes an air intake pipe 91. The rear end of the air intake pipe 91 is fixedly connected to the front end of the air intake valve 17. A fixing frame 92 is fixedly installed in the middle of the inner end of the air intake pipe 91. A follower shaft 93 is rotatably connected to the middle of the surface of the fixing frame 92 via a bearing. The front end of the follower shaft 93 passes through the front side of the fixing frame 92. A plurality of circumferentially distributed rotating blades 94 are fixedly installed on the outer side of the front end of the follower shaft 93. A first bevel gear 95 is fixedly installed at the rear end of the follower shaft 93. A second bevel gear 96 is meshed with the right side of the first bevel gear 95. A first rotating shaft 97 is fixedly installed at one end. A third bevel gear 98 is fixedly installed at the end of the first rotating shaft 97 away from the second bevel gear 96. A fourth bevel gear 99 is meshed with the front side of the third bevel gear 98. A second rotating shaft 910 is fixedly installed at the front end of the fourth bevel gear 99. A rotating bar 912 is fixedly installed at the front end of the second rotating shaft 910. A cleaning scraper 913 is fixedly installed at the end of the rotating bar 912 near the intake pipe 91.

[0021] Specifically, the air intake filter mechanism 9 enables the external power supply and control of the air pump 6 via an external power source and controller. During the operation of the air pump 6, outside air enters the pneumatic turbine assembly 8 through the air intake filter mechanism 9 and the air intake valve 17. In this process, the air passes through multiple rotating blades 94, which in turn drives the follower shaft 93 to rotate. The follower shaft 93 directly drives the first bevel gear 95 to rotate, which in turn drives the second bevel gear 96 to rotate. The second bevel gear 96 then drives the first rotating shaft 97 to rotate. The rotation action involves the first rotating shaft 97 directly driving the third bevel gear 98 to rotate, the third bevel gear 98 driving the fourth bevel gear 99 to rotate, and the fourth bevel gear 99 driving the second rotating shaft 910 to rotate. The second rotating shaft 910 drives the rotating bar 912 and the cleaning scraper 913 to clean the impurities attached to the surface of the filter screen 914. This can filter impurities in the air entering the air intake pipe 91 and simultaneously clean the impurities filtered onto the surface of the filter screen 914, ensuring the air intake efficiency of the air intake pipe 91 and improving the water spraying effect of the water pump 10.

[0022] In this embodiment, the support mechanism 16 includes a tripod 161. The rear end of the tripod 161 is fixedly installed at the front end of the two front support frames 2. Two symmetrically arranged electric push rods 162 are fixedly installed on the front inclined surface of the tripod 161. A triangular support block 163 is fixedly installed at the end of the telescopic rod of each electric push rod 162.

[0023] Specifically, the support mechanism 16 enables the water pump 10 and the nozzle 14 to generate a reaction force when water spraying is required. At this time, the two symmetrically arranged electric push rods 162 can be powered and controlled simultaneously through an external power supply and an external controller. The output end of the electric push rod 162 drives the triangular support block 163 to move diagonally downward. When the lower end of each triangular support block 163 contacts the ground, the power supply and control of the two symmetrically arranged electric push rods 162 can be stopped, which improves the stability of the device during the water spraying process.

[0024] In this embodiment, a base plate 3 is fixedly installed at the lower end of each support frame 2, and a locking caster wheel 4 is provided at the lower end of each base plate 3.

[0025] Specifically, the entire device can be moved using the base plate 3 and the locking casters 4.

[0026] In this embodiment, the first rotating shaft 97 is rotatably connected to the outer end of the intake pipe 91 through a bearing, and the right end of the first rotating shaft 97 passes through the outside of the intake pipe 91.

[0027] Specifically, ensure that the first rotating shaft 97 does not interfere with the intake pipe 91 during rotation.

[0028] In this embodiment, the outer end of the second rotating shaft 910 is rotatably connected to the contact frame 911 via a bearing. The front end of the second rotating shaft 910 passes through the front side of the contact frame 911, and the contact frame 911 is fixedly installed on the outer wall of the air intake pipe 91 at one end near the air intake pipe 91.

[0029] Specifically, the stability of the second rotating shaft 910 during rotation can be improved by the contact frame 911.

[0030] In this embodiment, the lower end of the water tank 11 is fixedly installed on the upper end of the workbench 1, and a water supply pipe 12 is fixedly connected to the middle right side of the upper end of the water tank 11.

[0031] Specifically, this ensures the stability of water tank 11 during operation.

[0032] In this embodiment, the pneumatic turbine assembly 8 is fixedly installed on the upper end of the workbench 1 near one end of the workbench 1, and the vertical end of the air pipe 15 is located on the front side of the workbench 1.

[0033] Specifically, ensure the stability of the pneumatic turbine assembly 8 during use.

[0034] In this embodiment, the pneumatic turbine assembly 8 includes a pneumatic turbine housing 81. A central impeller 83 is rotatably connected to the right side of the inner wall of the pneumatic turbine housing 81 via a bearing. The right end of the central impeller 83 is connected to the left end of the central shaft 18 via a coupling. Multiple impeller blades 84 arranged in a circular pattern are fixedly installed on the outer end of the central impeller 83. An airflow pipe 85 is fixedly connected to the upper front end of the pneumatic turbine housing 81. The airflow pipe 85 is arranged in a horizontal straight line. Both ends of the airflow pipe 85 are provided with air vents 86. A pneumatic turbine observation window 82 is detachably installed on the left end of the pneumatic turbine housing 81.

[0035] Specifically, the pneumatic turbine assembly 8 can amplify the torque of the gas entering the pneumatic turbine housing 81, thereby achieving a pressurization effect.

[0036] Working principle: When using the device, it can be manually pushed to move it to the predetermined position. Then, each locking caster 4 can be locked. Next, power is supplied to the air pump 6, regulating valve 7, pneumatic turbine assembly 8, and water pump 10 via an external power supply and controller. The air pump 6 then draws outside air into the air intake pipe 91. The air then passes through the air intake valve 17, regulating valve 7, pneumatic turbine assembly 8, and vent pipe 15 to the inlet of the water pump 10, thus pressurizing and spraying water. The water pump 10 then pumps water from the water tank 11, and the water is directly pressurized and sprayed from the nozzle 14 into the air intake pipe. During the intake process, outside air passes through the intake filter mechanism 9 and the intake valve 17 into the pneumatic turbine assembly 8. During this process, the air passes through multiple rotating blades 94, which in turn drive the follower shaft 93 to rotate. The follower shaft 93 directly drives the first bevel gear 95 to rotate, which in turn drives the second bevel gear 96 to rotate. The second bevel gear 96 drives the first rotating shaft 97 to rotate, which in turn drives the third bevel gear 98 to rotate. The third bevel gear 98 drives the fourth bevel gear 99 to rotate, which in turn drives the second rotating shaft... The second rotating shaft 910 rotates, driving the rotating bar 912 and the cleaning scraper 913 to clean the impurities attached to the surface of the filter screen 914. During operation, the water pump 10 and nozzle 14 generate a reaction force. At this time, the two symmetrically arranged electric push rods 162 can be simultaneously powered and controlled via an external power supply and controller. The output end of the electric push rod 162 drives the triangular support block 163 to move diagonally downwards. Power supply and control of the two symmetrically arranged electric push rods 162 cease once the lower surface of each triangular support block 163 contacts the ground. This improves the stability of the device during the water spraying process. When the water in the water tank 11 is used up, water can be added to the water tank 11 through the water pipe 12 via an external water filling device to ensure the continuity of the water spraying process. After the device finishes spraying, each locking universal wheel 4 can be unlocked, and the staff can push the entire device back to its original position. During the whole process, air enters directly into the pneumatic turbine housing 81 from the front vent 86. The air is directly driven by multiple circumferentially distributed impeller blades 84, which in turn drive the central impeller 83 to rotate. The central impeller 83 directly drives the central shaft 18 to rotate.
