Description

Technical Field

[0001] The invention relates to the technical field of water spray fire extinguishing, in particular to a water spray fire extinguishing device for coal mine fire extinguishing which is convenient for preventing clogging. Background Art

[0002] Coal mine fire extinguishing equipment refers to the extinguishing of underground fires. For any fire to occur, there must be combustibles, air supply and heat source at the same time, none of which can be missing. Mine fire extinguishing is to remove one, two or all of the combustion factors. Water source fire extinguishing is one of the important processes for quickly extinguishing a fire in a coal mine.

[0003] This prior art solution has the following deficiencies when used: in the traditional fire extinguishing device, the fire extinguisher holds the pipe and carries the fire extinguishing pipe to the fire location to extinguish the fire. Without professional training, it takes a lot of strength to pick up the pipe with a large impact force, and the water in the coal mine is relatively turbid, which can easily cause the nozzle to be blocked; the angle of the nozzle cannot be adjusted, so the nozzle cannot effectively spray water to extinguish the fire at the source, which reduces the efficiency of fire extinguishing; it is inconvenient to dock and install the nozzle on the device with the pipe, which results in a long time for splicing the device, resulting in the inability to extinguish the fire source in the first time.

[0004] The invention discloses a water spraying device for fire extinguishing in coal mines, which is convenient for preventing clogging. The water spraying device comprises a spray gun, a docking block is fixedly connected inside, a filter screen is connected on the surface of the docking block, and a riveted connection structure is formed between the docking block and the filter screen, a rotating shaft is movably connected inside the filter screen, a curved scraper is connected through the surface of the rotating shaft, and a filter screen and a rubber pad are attached to the surface of the curved scraper. The water spraying device for fire extinguishing in coal mines, which is convenient for preventing clogging, comprises a rotating block driving a fixed block to be threadedly connected with the spray gun, so that the spray gun and the docking joint are fixed to each other, when water flows into the interior of the spray gun, a spoiler will divert the water flow, so that the water flow forms a certain impact force on the curved scraper, causing the curved scraper to rotate, so that when the filter screen filters the water, the curved scraper can scrape away the filtered waste residue, avoiding impurities in the water, and causing clogging inside the spray gun.

[0005] The above technical solution cleans the filter screen by an arc-shaped scraper, but after cleaning, the impurities inside the filter screen cannot be effectively cleaned and discharged, and will still adhere to the filter screen and wait for the next cleaning, and so on and so forth, so improvement is needed.

[0047] Among them, the transmission belt assembly 3 can be composed of a belt and a pulley, or a chain and sprocket structure, so that the adjustment support assembly 6 can rotate along with the power output assembly 2. The power output assembly 2 is provided with corresponding controls and reducer components, which can control the rotation of the output shaft, so as to achieve the purpose of accurately controlling the direction of the diversion cleaning pipe assembly 5.

[0048] In some embodiments, the power output assembly 2 and the transmission belt assembly 3 may also use other adjustable angle components to achieve the purpose of accurately controlling the rotation angle of the adjustable support assembly 6. The adjustable support assembly 6 can be controlled to rotate to both sides more than 90° but less than 180° after the axis of the adjustable support assembly 6 overlaps with the axis of the movable fire truck body assembly 1, thereby ensuring the area it can cover.

[0051] In this embodiment, the resistance rod 63 and the support column 61 are located on both sides of the adjustable support assembly 6, and the connecting end of the piston rod of the electric telescopic rod 65 and the resistance rod 63 is penetrated and arranged in the opening 64.

The discharge pipe 55 is arranged through the shunt cleaning pipe assembly 5. A control valve assembly 56 is installed on the discharge pipe 55. The discharge pipe 55 can be closed through the control valve assembly 56 to ensure the stability of the water pressure in the shunt cleaning pipe assembly 5. And impurities can enter the connecting pipe 54 through the action of the cleaning brush assembly 573, and can also enter the discharge pipe 55 through the connecting pipe 54. After the fire extinguishing is completed, they can be discharged through the discharge pipe 55.

[0059] In this embodiment, the connecting water supply fitting 4 is arranged at one end of the shunt cleaning pipe assembly 5. A plurality of shunt pipes 51 are arranged through one end of the connecting water supply fitting 4 and the shunt cleaning pipe assembly 5 connected thereto. The connecting water supply fitting 4 can be connected to an external high-pressure water supply device, so as to realize the high-pressure water delivery into the connecting water supply fitting 4 and the shunt cleaning pipe assembly 5, increase the spraying coverage area, and better carry out the fire extinguishing operation by increasing the water flow impact force.

[0060] Among them, the end connecting the water supply pipe fitting 4 and the diversion cleaning pipe assembly 5 is closed, the cross-section of the water supply pipe fitting 4 is circular, and the area of ​​the cross-section of the water supply pipe fitting 4 is greater than the sum of the cross-sectional areas of multiple diversion pipes 51, that is, the water supply pipe fitting 4 adopts a tube body with one end closed, and its closed end is the end connected to the diversion cleaning pipe assembly 5, and in order to increase the pressure of water entering the diversion pipe 51 by changing the area, the shape of the connecting position of the diversion pipe 51 and the water supply pipe fitting 4 can be set to a trapezoidal structure, that is, the area of ​​the end where the diversion pipe 51 and the water supply pipe fitting 4 are connected is large and gradually shrinks, and at the same time, the position where the diversion pipe 51 and the water supply pipe fitting 4 are connected can be set to a fan shape so as to evenly penetrate the water supply pipe fitting 4, and at the same time, the fan-shaped setting can effectively make the area of ​​multiple fans slightly smaller than the area of ​​the water supply pipe fitting 4, thereby ensuring that the water flow can be diverted.

The driving wheel assembly 11 can be set as a device that can be automatically moved by a remote controller according to actual conditions to improve the safety during fire fighting; it can also be set as a simple cart body structure and set according to environmental requirements.

[0062] In the present invention, when in use, the water supply pipe fitting 4 is connected to the external high-pressure water supply pipeline, so that the water flow can be evenly distributed in multiple diverter pipes 51, and the caliber of the outlet end of the diverter cleaning pipe assembly 5 will be reduced, so that the area of ​​the water outlet end of the diverter pipe 51 can be compressed, which helps to increase the water flow coverage area.
