Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a large-scale fine water mist fire extinguishing device. Background Art

[0002] Firefighting equipment refers to various equipment used to prevent, control and extinguish fires. Common firefighting equipment includes fire extinguishers, fire hydrants, fire hoses, and automatic sprinkler systems. The role of these equipment is to provide necessary tools and equipment when a fire occurs to protect people's lives and property. The use and maintenance of firefighting equipment requires professional operation and management to ensure its normal operation and effective response to fires. Among the many firefighting equipment, a water mist fire extinguishing device is involved. The mist fire extinguishing device is a firefighting device that uses fine water mist particles to extinguish fires. It sprays water into tiny droplets to form water mist, which absorbs the heat in the fire area and lowers the temperature, thereby suppressing the development of the fire and extinguishing the fire.

[0003] Existing fire extinguishing devices are usually composed of a water pump, a sprinkler, a fixing frame and a spray duckbill. During operation, the sprinkler will spray its water mist. However, the influence of external natural wind may cause the water mist to be blown away or deviate to other places, making it impossible for the water mist to be accurately sprayed to the intended target location. Therefore, technical personnel in this field provide a large-range fine water mist fire extinguishing device to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a large-scale fine water mist fire extinguishing device, which can spray over a large horizontal and vertical range and can also generate a wind curtain to protect the water mist to prevent the natural wind from blowing the water mist away.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A large-scale water mist fire extinguishing device, comprising a base, a blower mechanism is fixedly arranged on one side of the upper end of the base, a connection conversion mechanism is fixedly arranged on the other side of the upper end of the base, a first rotating sleeve is fixedly arranged in the middle of the upper end of the connection conversion mechanism, a protective shell is rotatably arranged on the inner surface of the first rotating sleeve, and a bellows is fixedly arranged at the front of the upper end of the connection conversion mechanism;

[0007] The upper end of the connection conversion mechanism is fixedly provided with a fixing mechanism, the upper end of the protective shell is fixedly provided with a water sprayer, the upper end of the protective shell is fixedly provided with an outward-turned air outlet, the upper end of the outward-turned air outlet is fixedly provided with a fixing sleeve, the upper end of the water sprayer is fixedly provided with a handle at the rear, and the front end of the water sprayer is rotatably provided with a control mechanism;

[0008] Through the above technical scheme, the wind is blown into the interior of the bellows through the blowing mechanism through the connecting conversion mechanism, and then the wind is blown into the outward-turning air outlet by the bellows. The connecting conversion mechanism can transmit the anti-U-turn force on the one hand, and secondly, the water flow can be directly delivered to the interior of the sprinkler. The sprinkler cooperates with the control mechanism to spray water mist over a large range.

[0009] Further, the blower mechanism comprises a first outer frame, a switch is fixedly arranged on one side of the first outer frame, a filter air suction frame is fixedly arranged at the front and rear ends of the outer frame, and a transmission pipe is fixedly arranged on one side of the first outer frame;

[0010] Through the above technical solution, the air flow is sucked into the interior through the filter air suction frame of the first outer frame, and then the hair dryer is configured to convert the gas, and finally the air flow is discharged through the transmission pipe.

[0011] Furthermore, the connection conversion mechanism comprises a second outer frame, a water pipe is fixedly provided through the middle of the inner bottom surface of the second outer frame, and a connection conversion pipe is fixedly provided on one side of the inner side of the second outer frame;

[0012] Through the above technical solution, water flows through the protective shell through the water pipe and then flows into the interior of the sprinkler, and then the conversion pipe is connected to allow the air blowing mechanism to blow the airflow from the transmission pipe to the outward-turned air outlet and then spray out the airflow.

[0013] Furthermore, the fixing mechanism comprises two supporting columns, a protective shell is fixedly provided on one side of the upper end of the two supporting columns, and a second rotating sleeve is rotatably provided on the inner surface of the protective shell;

[0014] Through the above technical solution, the protective shell is fixed by the support column, and then the protective shell can be rotated by the second rotating sleeve.

[0015] Furthermore, the control mechanism comprises a rotating plate, a fixing ring is fixedly arranged inside the rotating plate, a rotating duckbill is slidably arranged inside the fixing ring, and a spring is fixedly arranged on one side of the rotating duckbill;

[0016] Through the above technical solution, the rotating duckbill can be rotated by rotating the rotating plate to change into horizontal spray or vertical spray. A fixing rod is connected between the fixed ring and the rotating duckbill to fix the rotating duckbill. At the same time, the fixing rod is rotatably set inside the fixed ring and is connected to other structures through a spring to fix the rotating duckbill.

[0017] Furthermore, a sliding block is fixedly provided on one side of the spring, a connecting plate is fixedly provided on the outer surface of the sliding block, and a slotted block is fixedly provided on the lower side and one side of the front end of the rotating plate;

[0018] Through the above technical solution, the rotating duckbill can achieve horizontal spray and vertical spray through the spring and the sliding block, and can be switched. When the switch is required, the connecting plate is pushed inward, and then the connecting plate moves inward with the sliding block, and then the sliding block slides on the inner surface of the fixed ring to the inside of the next slotted block. The spring will pop the sliding block out to fix it, completing the change of the spray direction of the rotating duckbill.

[0019] Furthermore, one end of the bellows is connected to the connection conversion mechanism and the other end is connected to the outward-turned air outlet;

[0020] Through the above technical solution, the bellows directs the airflow out from the inside of the connecting conversion tube and then directly into the inside of the outward-turned air outlet, so that the outward-turned air outlet sprays air outward to form an air curtain, which resists the influence of natural wind on the water mist sprayed by the sprinkler, ensuring that the water mist can be used for fire extinguishing normally.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes a large-scale fine water mist fire extinguishing device. The airflow of the blower mechanism flows out from the output pipe from the inside of the connecting conversion pipe and then directly into the inside of the outward-turned air outlet, so that the outward-turned air outlet sprays air outward to form an air curtain to resist the influence of natural wind on the water mist sprayed by the sprinkler, so that the water mist can reduce the influence of natural wind on it, and then extinguish the fire.

[0023] 2. The utility model proposes a large-scale fine water mist fire extinguishing device. When the duckbill needs to be rotated for turning in different scenes, the connecting plate is pushed inward, and then the connecting plate moves inward with the sliding block, and then the sliding block slides on the inner surface of the fixed ring to the inside of the next slotted block. The spring will pop out the sliding block, so that the rotating duckbill can turn, which is suitable for different scenes and has a better fire extinguishing effect.
