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 and convenient for preventing blockage. Background Art

[0002] Coal mine fire extinguishing equipment is used to extinguish underground fires. For any fire to occur, combustible materials, air supply, and a heat source are essential. Mine fire extinguishing aims to eliminate one, two, or all of these factors. Water extinguishing is a crucial step in quickly extinguishing a coal mine fire.

[0003] This existing technical solution has the following shortcomings 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 large impact, and the water in the coal mine is relatively turbid, which can easily cause the nozzle to be clogged; the angle of the nozzle cannot be adjusted, so the nozzle cannot effectively spray water to extinguish the source of the fire, which reduces the efficiency of fire extinguishing; it is inconvenient to connect the nozzle on the device with the pipe for installation, which leads to a long time for splicing the device, resulting in the inability to extinguish the fire source in the first time.

[0004] Publication number CN113786573B discloses a water spray fire extinguishing device for coal mine fire extinguishing that is convenient for preventing clogging. The device comprises: a spray gun, a fixedly connected docking block inside the spray gun, a filter screen connected to the surface of the docking block, and a riveted connection structure between the docking block and the filter screen, a rotating shaft movably connected to the filter screen, a curved scraper connected to the surface of the rotating shaft, a side surface of the curved scraper being connected to the filter screen, and a rubber pad, the surface of which is embedded in the inner wall of the spray gun. The water spraying device for coal mine fire extinguishing that is convenient for preventing clogging is characterized by the rotating block driving the fixed block to be threadedly connected to the spray gun, so that the spray gun and the docking block are fixed to each other. When water flows into the spray gun, the spoiler diverts the water flow, causing the water flow to exert a certain impact force on the curved scraper, causing the curved scraper to rotate. When the filter screen filters the water, the curved scraper can scrape away the filtered waste residue, thereby preventing impurities in the water from clogging the spray gun.

[0005] The above technical solution cleans the filter screen through 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, so it needs to be improved.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] Among them, the transmission belt assembly 3 can be composed of a belt and a pulley, or it can adopt 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 control and reducer components, which can control the rotation of the output shaft and 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 adopt other adjustable angle components to achieve the purpose of accurately controlling the rotation angle of the adjustment support assembly 6. The adjustment support assembly 6 can be controlled to rotate to both sides more than 90° but less than 180° after the axis of the adjustment support assembly 6 overlaps with the axis of the movable fire truck body assembly 1, ensuring the area it can cover.

[0049] In this embodiment, the diversion cleaning pipe assembly 5 is arranged at the upper end of the adjustment support assembly 6, and a support column 61 is fixed on one side of the upper end of the adjustment support assembly 6. The upper end of the support column 61 is rotatably connected to a fixing frame 62, and the fixing frame 62 is fixed to the lower end of the diversion cleaning pipe assembly 5. An opening 64 is opened on one side of the adjustment support assembly 6, and a resistance rod 63 is slidably installed in the adjustment support assembly 6. The upper end of the resistance rod 63 is rotatably connected to a sliding rod 66, and the sliding rod 66 is slidably installed at the lower end of the fixing frame 62. An electric telescopic rod 65 is fixed on one side of the lower end of the adjustment support assembly 6, and the piston rod end of the electric telescopic rod 65 is fixedly connected to the lower end of the resistance rod 63. The angle is adjusted by adjusting the support assembly 6 under the action of the power output assembly 2 and the transmission belt assembly 3, and the components in the adjustment support assembly 6 can adjust the lifting angle of the diversion cleaning pipe assembly 5, which helps to expand the coverage area.

[0050] Among them, a connecting component is fixed between the piston rod of the electric telescopic rod 65 and the resistance rod 63, and the connecting component passes through the opening 64, which can ensure that the electric telescopic rod 65 drives the resistance rod 63 to rise and fall. When the resistance rod 63 rises, it can drive the sliding rod 66 to move at the lower end of the fixed frame 62 to adapt to the situation after the fixed frame 62 is deflected, so as to achieve the purpose of adjusting the lifting angle of the diversion cleaning pipe assembly 5. By lifting the front end of the diversion cleaning pipe assembly 5 until the lifting angle is 45°, it helps to expand the spray coverage angle and better perform fire extinguishing operations.

[0051] In this embodiment, the interference rod 63 and the support column 61 are located on both sides of the adjustment support assembly 6, and the connecting end of the piston rod of the electric telescopic rod 65 and the interference rod 63 is arranged through the opening 64. Through the above design scheme, it can be ensured that the interference rod 63 can effectively push the fixing frame 62 to rotate when it is raised or lowered.

[0052] In this embodiment, a plurality of diverter tubes 51 are fixed at equal intervals on the side walls of the diverter cleaning tube assembly 5, an arc-shaped screen 52 is installed in the diverter tube 51, and a connecting tube 54 is installed at the opposite end of each of the plurality of diverter tubes 51. A circular tube 53 is fixed between the plurality of connecting tubes 54, and a linkage cleaning shaft assembly 57 is installed in the connected diverter tubes 51 and connecting tubes 54, and the linkage cleaning shaft assembly 57 is connected to the arc-shaped screen 52.

[0053] After the water flows into the diversion pipe 51, it can be filtered through the arc screen 52, and impurities will accumulate on the end of the arc screen 52 close to the water supply pipe 4. Through the operation of the linkage cleaning shaft assembly 57, the impurities on this side can be effectively cleaned to ensure the stable passage of water.

[0054] In this embodiment, the end where the connecting pipe 54 and the diversion pipe 51 are connected is through-set, 51 is a pipe structure with both ends through-set, the linkage cleaning shaft assembly 57 is rotatably sleeved in the through-ends of the connecting pipe 54 and the diversion pipe 51, a plurality of arc-shaped pressure plates 572 are fixed at equal intervals around the linkage cleaning shaft assembly 57, a connecting plate 571 is fixed at one end of the plurality of arc-shaped pressure plates 572 away from the linkage cleaning shaft assembly 57, a cleaning brush assembly 573 is fixed at one end of the connecting plate 571 away from the arc-shaped pressure plate 572, and the cleaning brush assembly 573 conflicts with the arc-shaped screen 52.

[0055] Among them, one end of the connecting pipe 54 and the diverter pipe 51 is connected through, that is, an opening is opened on the connecting surface of the connecting pipe 54 and the diverter pipe 51, and the area of ​​the opening is equal to the area where the connecting pipe 54 and the diverter pipe 51 are connected, and the axis of the linkage cleaning shaft assembly 57 is set in the opening, which can facilitate the rotation of the linkage cleaning shaft assembly 57 so that the cleaning brush assembly 573 can clean the arc screen 52, and the arc pressure plate 572 can effectively bear the force of the water flow impact to drive the linkage cleaning shaft assembly 57 to rotate. The arc pressure plate 572 can be set into a sheet or arc structure as needed. If it is set into an arc structure, the direction of the arc opening is located close to the direction of the water supply pipe 4, which can better withstand the impact force of the water flow.

[0056] In this embodiment, four partition plates 511 are provided in the diverter tube 51, and the four partition plates 511 are all arranged in the through ends of the diverter tube 51 and the connecting tube 54. The four partition plates 511 are all fixedly connected to the diverter tube 51, and the four partition plates 511 are respectively arranged at the four corners of the linkage cleaning shaft assembly 57. The four connecting plates 571 are located between the four partition plates 511, and the distance between the partition plate 511 and the side wall at one end of the connecting tube 54 is greater than the width of the cleaning brush assembly 573.

[0057] Among them, the partition plate 511 is arranged in the mouth on the connecting surface of the connecting pipe 54 and the diversion pipe 51, and the four partition plates 511 are respectively fixed at the four corners of the mouth. The distance between the partition plate 511 and the inner side wall of the mouth is greater than the width of the cleaning brush assembly 573, and the distance between the two partition plates 511 on one side of the linkage cleaning shaft assembly 57 is greater than the width of the connecting plate 571. The distance between the partition plates 511 on both sides of the linkage cleaning shaft assembly 57 is greater than the diameter of the linkage cleaning shaft assembly 57 and the sum of the diameters of the two arc-shaped pressure plates 572, which can ensure that the linkage cleaning shaft assembly 57 can rotate. We can understand it as opening a "King"-shaped opening, with the linkage cleaning shaft assembly 57 and the arc-shaped pressure plate 572 in the middle opening position, the connecting plate 571 in the vertical opening position, and the cleaning brush assembly 573 able to pass through the upper and lower opening positions.

[0058] In this embodiment, the end where the discharge pipe 55 is connected to the connecting pipe 54 is set to be through, and the lower end of the round pipe 53 close to the side connected to the water supply pipe 4 is penetrated by a discharge pipe 55, and the discharge pipe 55 is set to be penetrated on the diversion cleaning pipe assembly 5, and a control valve assembly 56 is installed on the discharge pipe 55. The discharge pipe 55 can be closed by the control valve assembly 56 to ensure the stability of the water pressure in the diversion 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 is extinguished, they can be discharged through the discharge pipe 55.

[0059] In this embodiment, the connecting water supply pipe fitting 4 is arranged at one end of the diversion cleaning pipe assembly 5, and multiple diversion pipes 51 are arranged through the end where the connecting water supply pipe fitting 4 and the diversion cleaning pipe assembly 5 are connected. The connecting water supply pipe fitting 4 can be connected to an external high-pressure water supply equipment, and high-pressure water can be transported into the connecting water supply pipe fitting 4 and the diversion cleaning pipe assembly 5, thereby increasing the area covered by the spraying, and by increasing the impact force of the water flow, better fire extinguishing operations can be carried out.

[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 pipe 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 connection 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. 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. 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, ensuring that the water flow can be diverted.

[0061] In this embodiment, the four corners of the lower end of the movable fire truck body assembly 1 are jointly installed with a driving wheel assembly 11. 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 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 4 is connected to the external high-pressure water supply pipeline, which can evenly distribute the water flow to the multiple diversion pipes 51, and the diameter of the outlet end of the diversion cleaning pipe assembly 5 will be reduced, which can compress the area of ​​the water outlet end of the diversion pipe 51, helping to increase the water flow coverage area. When the water flows in the diversion pipe 51, it will impact the arc-shaped pressure plate 572 to rotate the linkage cleaning shaft assembly 57, which can enable the cleaning brush assembly 573 to clean impurities on the arc-shaped screen 52 and transport them into the connecting pipe 54. After the fire is extinguished, the control valve assembly 56 is opened to facilitate the discharge of impurities.

[0063] The power output assembly 2, the transmission belt assembly 3 and the adjustment support assembly 6 arranged on the movable fire truck body assembly 1 can drive the diversion cleaning pipe assembly 5 to rotate, making it easy to adjust the direction and lifting angle of the diversion cleaning pipe assembly 5 to better perform fire extinguishing operations.

[0064] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
