Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to an anti-blocking high-pressure fine water mist fire extinguishing device. Background Art

[0002] Forest fire is the most dangerous enemy of the forest and the most terrible disaster in the forestry industry. It will bring the most harmful and devastating consequences to the forest. Forest fire not only burns large tracts of forests and harms animals in the forest, but also reduces the reproductive capacity of the forest, causes soil infertility and destroys forest water conservation, and even causes the ecological environment to lose balance. In forest fire prevention, high-pressure fine water mist fire extinguishing devices are needed.

[0003] Referring to the existing patent publication number: CN215505224U, a blockage-proof high-pressure fine water mist fire extinguishing device includes a base plate, a buffer mechanism is evenly installed on the top of the base plate, and a bearing plate is installed on the top of the buffer mechanism, a water tank is installed at one end of the top of the bearing plate, a filter is installed horizontally above the inside of the water tank, and a water inlet is installed on the top of the water tank, and a booster pump is installed on the top of the bearing plate on the right side of the water tank. During the movement of the utility model, the base plate will be subjected to the force of the ground during the shaking of the device, and the pressure will be transferred to the movable rod. After the movable rod is subjected to the force, it will push the movable plate to move in the direction of the second spring, and the pressure is buffered by the elastic action of the second spring, so as to extend the service life of the device.

[0004] However, in actual use, the existing high-pressure fine water mist fire extinguishing device is usually equipped with a filter screen inside the device to filter impurities in order to avoid clogging of the nozzle when extinguishing the fire. However, when the filter screen filters and purifies the water for a long time, more and more impurity particles tend to accumulate on its surface, which makes it easy to cause the water pressure to decrease when the water source is drawn, thus affecting the fire extinguishing effect. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and propose an anti-blocking high-pressure fine water mist fire extinguishing device. The utility model cooperates with the anti-blocking mechanism and the transmission mechanism so that when the water is filtered through the filter, the anti-blocking mechanism and the transmission mechanism can knock the filter to a certain extent, so that the filter can vibrate and move, and the impurities on its surface can move, so as to avoid the impurities from accumulating on the filter and affecting the water pressure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The base has universal wheels for supporting movement all around the lower part;

[0017] The utility model is further configured that a push rod is connected to the surface of the base, a conveying mechanism is installed on the upper part of the base, and a diversion mechanism is installed on the upper part of the base.

[0018] The utility model is further configured that the diversion mechanism includes: a bracket, a diversion part, a partition, a second rotating member, a drainage part and a nozzle;

For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0034] Reference Figure 1-4, a blockage-proof high-pressure fine water mist fire extinguishing device, comprising: a base 1, the lower part of which is constructed with universal wheels for supporting movement; a water tank 3, which is arranged on the upper part of the base 1 and has a water injection port 4 for water replenishment on the surface, and a filter screen 11 arranged obliquely is installed inside the water tank 3. The water required for fire extinguishing is stored in the water tank 3, and when water is injected into the water tank 3 through the water injection port 4, the filter screen 11 inside the water tank 3 can filter and remove impurities from the water source to prevent impurities in the water source from clogging the nozzle 8 and other positions and affecting the fire extinguishing effect; anti-blocking mechanism, It is movably installed inside the water tank 3, and the anti-blocking mechanism is configured to be able to make circular motion around the axis of the first rotating member 15 included therein, so that the anti-blocking mechanism can rotate continuously to ensure continuous action on the filter 11; a transmission mechanism connected to the anti-blocking mechanism is installed inside the water tank 3, and the anti-blocking mechanism can be driven to move through the transmission mechanism, so that the anti-blocking mechanism can perform certain actions on the filter 11 after operation, and the filter 11 can avoid the accumulation of more impurities at the same position on its surface after the movement, which affects the water pressure during fire extinguishing.

[0035] Specifically, refer to Figure 2-3 The anti-blocking mechanism includes: a first rotating member 15, a torsion spring 18, an elastic member 16 and a knocking member 17; the first rotating member 15 is horizontally installed inside the water tank 3, the torsion springs 18 are respectively installed on both sides of the surface of the first rotating member 15, the elastic members 16 are distributed in a ring array on the surface of the first rotating member 15, and the knocking members 17 are installed at one end of the elastic member 16 away from the first rotating member 15. Through this implementation, the elastic member 16 and the knocking member 17 can rotate under the action of the first rotating member 15, and the first rotating member 15 will also drive the torsion spring 18 to be compressed, and the centrifugal force generated during the rotation can throw the knocking member 17 outward for a certain distance. At this time, under the elastic traction of the elastic member 16, the knocking member 17 can reciprocate, thereby improving the flexibility and knocking effect of the knocking member 17.

[0036] Furthermore, the knocking piece 17 is located directly below the filter 11 and in contact with the filter 11. Through this design, the knocking piece 17 can repeatedly knock the filter 11 when it rotates and reciprocates, so that the filter 11 can produce a certain vibration or phase activity to drive the impurities accumulated on its surface to vibrate and shift, thereby avoiding the accumulation of impurities to block the filter 11 and affect the water pressure.

[0037] Specifically, refer to Figure 2-3The transmission mechanism includes: a connecting member 14, a pulley 12 and a floating member 13; the pulley 12 is installed at the lower part of the water tank 3, one end of the connecting member 14 is connected to the surface of the first rotating member 15, the floating member 13 is installed at the other end of the connecting member 14, and the connecting member 14 is passed through the surface of the pulley 12. Through this embodiment, when water is poured into the water tank 3, the floating member 13 can be driven to rise by the gradual rise of the water level. Since the connecting member 14 is wrapped around the surface of the first rotating member 15, the buoyancy generated by the floating member 13 can be greater than the elastic potential energy of the torsion spring 18, so that under the action of buoyancy, the first rotating member 15 can be driven to rotate through the connecting member 14 to transmit the action, so that the filter screen 11 can be automatically processed when water is poured, reducing related operations and being more convenient.

[0038] Furthermore, a push rod 2 is connected to the surface of the base 1, and the push rod 2 is used to facilitate the movement of the device to the fire extinguishing position, thereby reducing labor intensity and preventing the device from being difficult to move. A conveying mechanism is installed on the upper part of the base 1, and a diversion mechanism is installed on the upper part of the base 1. The conveying mechanism can be used to convey and supply water, and the diversion mechanism can be used to divert and use high-pressure water flow, thereby improving flexibility and fire extinguishing effect.

[0039] Specifically, refer to Figure 1 and Figure 4 The diversion mechanism includes: a bracket 6, a diversion part 7, a partition 20, a second rotating member 21, a drainage part 19 and a nozzle 8; the bracket 6 is installed on the upper part of the base 1, the diversion part 7 is installed on the surface of the bracket 6 and has a cavity inside, the partition 20 is installed on the inner side of the diversion part 7 through the second rotating member 21 arranged with the diversion part 7 through an axis, the drainage part 19 is constructed on the surface of the diversion part 7, and the nozzle 8 is installed on the surface of the drainage part 19. Through this embodiment, after the high-pressure water flow flows into the diversion part 7, the water flow can push the partition 20 to rotate under the action of the second rotating member 21, and the surface of the diversion part 7 is constructed with multiple drainage parts 19, so that the discharged water flow can be connected to multiple different nozzles 8. When no nozzle is connected, the drainage part 19 is in a closed state, so that it can be used as needed, and the water pressure generated is consistent, which makes it more flexible and more selective when extinguishing the fire, thereby improving the fire extinguishing effect.

[0040] Specifically, refer to Figure 1 The conveying mechanism includes: a booster pump 5, a water inlet pipe 10 and a water outlet pipe 9; the booster pump 5 is installed on the surface of the base 1, the water inlet pipe 10 is connected between the booster pump 5 and the water tank 3, and the water outlet pipe 9 is connected between the booster pump 5 and the diversion part 7. Through this embodiment, the booster pump 5 can draw water from the water tank 3 through the water inlet pipe 10 when working, and the drawn water flow is pressurized under the action of the booster pump 5, and then the water flow will be supplied to the position of the diversion part 7 by the water outlet pipe 9, which is convenient for subsequent diversion fire extinguishing treatment.

[0041] Working principle: When using the utility model, first, when water is poured into the water tank 3, the water level gradually rises to drive the floating member 13 to rise. Since the connecting member 14 is wrapped around the surface of the first rotating member 15, the first rotating member 15 can be driven to rotate through the connecting member 14 under the action of buoyancy. Since the buoyancy generated by the floating member 13 can be greater than the elastic potential energy of the torsion spring 18, the first rotating member 15 can compress the torsion spring 18 after rotation and drive the elastic member 16 and the knocking member 17 to move. Under the action of the elastic member 16, the knocking member 17 can perform a certain reciprocating knock on the filter screen 11, so that the filter screen 11 can vibrate and move, and the impurities on its surface can move to avoid the accumulation of impurities on the filter screen 11 and affect the water pressure. Then, the device can be moved to the position where the fire needs to be extinguished through the universal wheels at the bottom. When the booster pump 5 is working, it can draw water from the water tank 3 through the water inlet pipe 10 and pressurize it, so that the water flows to the position of the diversion part 7 through the water outlet pipe 9. When the water level is gradually reduced due to the use of water for fire extinguishing, the torsion spring 18 will drive the first rotating member 15 to reset and rotate, so that the elastic member 16 and the knocking member 17 are reversed, and the filter screen 11 can also be knocked. After the high-pressure water flow flows into the diversion part 7, the water flow can push the partition 20 to rotate under the action of the second rotating member 21, and the surface of the diversion part 7 is constructed with multiple drainage parts 19, so that the discharged water flow can be connected to multiple different nozzles 8. When no nozzle is connected, the drainage part 19 is in a closed state, so that it can be used as needed, and the water pressure generated is consistent, which makes it more flexible and selective when extinguishing a fire, thereby improving the fire extinguishing effect.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
