Description

Technical Field

[0001] The present invention relates to the technical field of fire monitors, in particular to an automatic fire extinguishing monitor. Background Art

[0002] Fire monitor, also known as fire water monitor, is an important fire-fighting equipment for long-distance fire fighting. Fire monitors are divided into fire water monitors and fire foam monitors. Fire water monitors are fire-fighting equipment that sprays water to extinguish general solid materials from a long distance. Fire foam monitors are fire-fighting equipment that sprays air foam to extinguish Class A, B, and C liquid fires from a long distance.

[0003] During the use of traditional fire monitors, although they have the function of automatically and remotely extinguishing fires, traditional fire monitors cannot easily convert between water columns and water mist. In this way, when encountering general solid material fires, such as fires of solid combustibles such as wood, paper, cotton and linen, when the fire is in the early stages, the fire is small and concentrated, and the burning materials are relatively regular, columnar water is more effective in extinguishing the fire. At this time, columnar water is needed for fire extinguishing operations. For electrical equipment fires, oil fires, dust fires, large-scale fires, fires where people are trapped, etc., water mist fire extinguishing is required to ensure the safety of personnel and to control the fire on a larger scale. Therefore, fire monitors that cannot be easily converted cannot effectively extinguish fires in complex fire situations, and thus cannot meet the needs of efficient fire extinguishing.

[0004] In order to solve the above problems, a kind of automatic fire extinguishing fire monitor is needed. Summary of the Invention

When the flow rate of the fire extinguishing liquid through the device is large, the device will spray a water column, which can effectively extinguish the single-point fire location.

[0020] 3. The device utilizes the serial fixing effect of the connecting components to ensure that the integrity of the device as a whole will not be destroyed while adjusting left and right, up and down, and utilizes the entire array of guide rods to ensure the stable movement of the push ring block. The circular array setting can better distribute the force of the push ring block and avoid the problem of resistance during the movement of the push ring block.

[0021] 4. The device uses the spiral distribution of arc grooves to ensure that the external gas passes through the spiral effect for the first acceleration. After passing through the arc grooves, the gas will pass through the cone grooves again, and the channel of the cone grooves will become smaller, thereby achieving the second acceleration and ensuring the growth rate of the gas.

The block 620 can guide the external gas into the arc groove 619 better through the guiding effect of the inclined surface.

[0037] The working principle of the above embodiment is:

[0038] When the device is in use, the fixed base 1 is connected to the equipment for conveying fire extinguishing liquid to ensure the normal spraying function of the device. The controller 5 in the device is a JB-QB-TX3001A model controller 5, and the surface of the JB-QB-TX3001A controller 5 is provided with a 485 interface extension terminal, which can be connected to other devices with 485 communication functions through the 485 interface extension, such as connecting to a remote monitoring terminal or related equipment of a fire control center, and transmitting alarm information, equipment status and other data to the remote terminal to realize remote monitoring. This controller 5 and the technology for connecting to remote control equipment are both existing mature technologies, and this application does not go into too much detail.

[0039] When the device needs to adjust the spraying posture, the left and right and up and down movements of the spraying assembly 6 can be achieved through the front and rear connecting assemblies 4. The rear connecting assembly 4 uses the waterproof motor 408 to drive the worm gear 403 on the worm 404 to rotate, thereby ensuring that the pipe connected in the worm gear 403 rotates relative to the position of the connecting ring block 401, and the front and rear connecting assemblies 4 are staggered and vertically arranged. In this way, the two connecting assemblies 4 can produce different driving and rotating effects under the rotation of the worm gear 403 and the worm 404, thereby ensuring the left and right and up and down movements of the spraying assembly 6. During operation, the connecting line 9 has sufficient length to ensure the normal movement of the spraying assembly 6;

[0040] When extinguishing a fire, if it is necessary to spray water mist at the fire extinguishing location, the fire extinguishing liquid is introduced into the water spray barrel 601 in the spray assembly 6 through the fixed base 1, the U-shaped connecting pipe 2 and the spray elbow 3. At this time, the water flow will be ejected through the conical spray barrel 602 by pushing the ring block 608 and the nozzle 609. In this process, the water pressure of the fire extinguishing liquid is less than the elastic force of the first springs 610, and the nozzle 609 will not move. At the same time, the flow of water will cause the air pressure at the flow location to decrease, so L Negative pressure will be generated at the upper end of the L-shaped straw 604, and the sealing cover block 613 will be moved away from the sealing ring block 614 under the suction force of the negative pressure. The tension spring 616 and the second spring 615 here are set with the same number of turns and thickness, but the elastic modulus of the tension spring 616 is greater than the elastic modulus of the second spring 615. Therefore, during the movement of the sealing cover block 613, the sealing ring block 614 will remain stationary. Therefore, at this time, the external gas will enter through the inner wall of the sealing ring block 614 and the gap between the sealing cover block 613 and the L-shaped straw 604. After entering the water spray barrel 601, the liquid after the gas-liquid mixture passes through the conical nozzle 602, a collision will occur, thereby producing an atomization effect. During the gas extraction process, the gas will first pass through a number of spirally arranged arc grooves 619. Through the acceleration effect of the spiral, due to the special shape of the spiral, the gas molecules will be constrained and guided by the groove wall. As the gas moves along the spiral groove, its flow path becomes longer. Within a certain space, the gas flow rate remains unchanged, while the flow area gradually becomes smaller, resulting in an increase in the gas flow rate. Moreover, passing through the conical groove 618 will reduce the gas passage space. Because when the gas passes through the structure of the conical groove, the shape of the conical groove makes the gas flow cross-sectional area gradually smaller. When the gas flows from the large end to the small end of the conical groove, due to the gradual reduction in the flow area, the gas flow rate will inevitably increase gradually, thereby achieving gas acceleration, and then accelerating the gas again. The accelerated gas passes through the sealing ring block 614 and enters the water spray barrel 601, ensuring sufficient gas-liquid mixing. Then, it can be better atomized and sprayed out through the collision of the conical nozzle 602.

[0041] When water jetting is required, the water pressure only needs to be increased. At this time, the water pressure will be greater than the elastic force of the first springs 610. In this way, the water pressure will push the nozzle 609 in the ring block 608 toward the conical nozzle 602. At this time, the nozzle 609 extends out of the conical nozzle 602, preventing the conical nozzle 602 from colliding with the fire extinguishing liquid, thereby ensuring the direct spraying effect of the fire extinguishing liquid. Moreover, when the pressure is high, the water flow in the water nozzle 601 is large, so the suction force generated at the end of the L-shaped suction pipe 604 will be greater. In this way, the tension of the tension spring 616 is less than the suction force generated by the liquid, so that the sealing ring block 614 will be sucked and then contacted with the sealing cover block 613 for sealing. In this way, no gas will be introduced, which will ensure that the fire extinguishing liquid will not be atomized. The fire extinguishing operation can be performed on single-point fires. By changing the water pressure, the requirements of different fires can be met, greatly improving the applicability of the device and ensuring the quality of use of the device. The rotating connection and penetration effect in the device are all sealed and will not affect the normal use function of the device.

[0042] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
