[0026] like Figure 1 As shown, an embodiment of the present invention provides a barrel body for containing fire foam liquid, including a foam liquid barrel 1, a liquid filling port 12 is arranged on the top of the foam liquid barrel 1, and a lid is installed on the liquid filling port 12. The fire foam liquid can be added into the foam liquid barrel 1 by opening the lid, and the lid can be fixed at the liquid filling port 12 after the addition is completed. At the same time, a plug can be installed at the bottom of the lid, and the plug can be a metal block or a rubber block. The bottom of the plug is consistent with the shape of the inner wall of the foam liquid barrel 1, and the fire foam liquid is prevented from adhering to the inner wall position of the liquid filling port 12 by the plug. Two drainage ports 13 are arranged at the bottom of the foam liquid barrel 1, and the two drainage ports 13 are connected with a pipeline. Stop valves are installed at the two liquid inlet ends of the pipeline. The stop valve is used to prevent the fire foam liquid from being discharged from the drainage port 13 during the transportation of the fire foam liquid. There is a fire pump (not shown in the figure), V-shaped plates 3 are fixed on the top and bottom of the inner wall of the foam liquid barrel 1, arc-shaped surfaces 1 20 are arranged on opposite sides of the inner wall of the foam liquid barrel 1, and arc-shaped surfaces 2 31 are arranged on both sides of the V-shaped plate 3. The V-shaped plate 3 divides the interior of the foam liquid barrel 1 into two cylindrical cavities 15, and the centers of the arc-shaped surfaces 1 20 and the arc-shaped surfaces 2 31 coincide with the centers of the corresponding cylindrical cavities 15. A fixing seat 11 is fixed to the bottom of the foam liquid barrel 1, and the foam liquid barrel 1 is fixed to the fire truck 2 through the fixing seat 11. During the process of using the foam liquid barrel 1 to transport the fire foam liquid, the fire foam liquid will shake in the foam liquid barrel 1. The water hammer effect generated during the transportation of the fire foam liquid is effectively reduced through the diversion of the arc-shaped surface 1 20 and the blocking of the arc-shaped surface 2 31, thereby improving the service life of the foam liquid barrel 1. The insides of the two cylindrical cavities 15 are both rotatably connected with hollow shafts 16, and a sealing ring is installed at the inner wall of the foam liquid barrel 1 corresponding to the hollow shaft 16. The sealing ring is used for sealing between the hollow shaft 16 and the foam liquid barrel 1, and a square plate 4 and a partition plate 6 are symmetrically arranged on the hollow shaft 16. A rubber scraper strip 5 is fixed to the side of the square plate 4. A driving mechanism 19 is arranged on the side of the foam liquid barrel 1, and the driving mechanism 19 is used to drive the hollow shaft 16 to rotate. The driving mechanism 19 is mainly composed of a square cover fixed to the rear side of the foam liquid barrel 1 and a reduction motor fixed to the rear side of the square cover. The rear ends of the two hollow shafts 16 extend into the square cover, and the rear ends of the two hollow shafts 16 are fixedly sleeved with bevel gears 1, and are rotatably connected with a rotating shaft in the square cover. Bevel gears 2 are fixed at both ends of the rotating shaft, and the two bevel gears 2 are respectively meshed with the corresponding bevel gears 1, and the output shaft of the reduction motor is fixedly connected to the rear end of the left hollow shaft 16 Then, when the hollow shaft 16 needs to rotate, the reduction motor is started, and the reduction motor drives the left hollow shaft 16 to rotate counterclockwise, and the hollow shaft 16 can drive the right hollow shaft 16 to rotate clockwise through the cooperation of the rotating shaft and the bevel gear 2. During cleaning, the driving mechanism 19 drives the two square plates 4 to make circular motion in the cylindrical cavity 15, and the rotation directions of the two square plates 4 are opposite, and the fire foam liquid adhering to the inner wall of the foam liquid barrel 1 and the V-shaped plate 3 is scraped off by the rubber scraper 5 on the square plate 4. During the cleaning process, there is no need to manually hold a spray gun to rinse the inner wall of the foam liquid barrel 1, and the cleaning is more convenient. At the same time, the rubber scraper 5 makes a circular motion in the cylindrical cavity 15, so as to scrape off the fire foam liquid adhering to the inner wall of the foam liquid barrel 1 and the V-shaped plate 3, and the cleaning is faster, thereby improving the cleaning efficiency of the fire foam liquid adhering to the inner wall of the foam liquid barrel 1.

[0027] like Figure 1 As shown, in this embodiment, a plurality of reinforcing ribs 10 are fixed on the foam liquid barrel 1, and the plurality of reinforcing ribs 10 are evenly distributed on the foam liquid barrel 1 at intervals. The reinforcing ribs 10 are used to improve the structural strength of the foam liquid barrel 1, effectively prevent the foam liquid barrel 1 from being deformed by force, and improve the service life of the foam liquid barrel 1.

[0028] like Figure 2-Figure 7As shown, in this embodiment, a cleaning assembly 8 is provided at the hollow shaft 16, and the cleaning assembly 8 includes a central circular tube 81 provided inside the hollow shaft 16, and a circular sleeve 87 and a connecting pipe 17 are fixed to the sides of the foam liquid barrel 1, respectively. The inner wall of the circular sleeve 87 is stepped, and the end of the hollow shaft 16 away from the driving mechanism 19 passes through the foam liquid barrel 1 and is rotatably connected to the inner wall of the circular sleeve 87. The circumferential surface of the central circular tube 81 is fixedly connected to the inner wall of the circular sleeve 87, and two drainage holes 82 are provided on the central circular tube 81. Two groups of through holes 84 are symmetrically provided on the hollow shaft 16, and each group of through holes 84 includes two rows of through holes 84. The square plate 4 is located between the two rows of through holes 84 of one group, and the partition plate 6 is located between the two rows of through holes 84 of the other group. The V-shaped plate 3 is located on the side away from the center of the cylindrical cavity 15. The space formed between the foam liquid barrel 1 and the foam liquid barrel 1 is a water storage chamber 14, in which water is stored. A water pump 86 is fixed on the inner wall of the foam liquid barrel 1 corresponding to the water storage chamber 14, and the connecting pipe 17 is connected to the water outlet of the water pump 86. A water inlet pipe 83 is fixed on the side of the foam liquid barrel 1 corresponding to the water storage chamber 14, and a manual ball valve is installed on the water inlet pipe 83. A sealing ring 88 is fixed on the inner wall of the hollow shaft 16, and the inner wall of the sealing ring 88 is fitted with the circumferential surface of the central circular tube 81. A rubber baffle 85 is fixed on the hollow shaft 16 at a position corresponding to the through hole 84. The rubber baffle 85 is used for one-way sealing of the through hole 84. The rubber baffle 85 includes an adhesion portion 852 and a flow channel 853. The adhesion portion 852 is fixed on the hollow shaft 16, and the flow channel 853 corresponds to the position of the through hole 84. When cleaning, the water pump 8 6 is operated to make the water in the water storage chamber 14 spray out from the position of the through hole 84. The water sprayed from the through hole 84 is sprayed onto the surface of the square plate 4 and the partition 6 through the guidance of the rubber baffle 85, and the fire foam liquid adhering to the square plate 4 and the partition 6 is flushed. A bearing is embedded in the inner wall of the circular sleeve 87. The inner wall of the bearing is fixedly connected to the circumferential surface of the end of the hollow shaft 16. The bearing is used to make the rotation of the hollow shaft 16 more stable and smooth. The sealing ring 88 is used for sealing between the hollow shaft 16 and the central circular tube 81 to prevent water from being discharged from the front end of the hollow shaft 16. When the rubber scraper 5 scrapes off the fire foam liquid, the water pump 86 is started. The water pump 86 transports the water in the water storage chamber 14 to the central circular tube 81 through the connecting pipe 17, and then sprays it out from the position of the water outlet 82. The water flow is then ejected from the through hole 84 on the hollow shaft 16, and the water flow squeezes the rubber baffle 85, causing the rubber baffle 85 to deform, so that the water flow flows to the position of the square plate 4 and the partition 6, and the fire-fighting foam liquid adhering to the square plate 4 and the partition 6 is cleaned by the flushing of the water flow. The connecting pipe 17 can be a hose and is connected to the central circular pipe 81 by a threaded connection. In an emergency, the connecting pipe 17 can be separated from the central circular pipe 81, and then the water in the water storage chamber 14 is transported out from the connecting pipe 17 by the water pump 86 for fire extinguishing. When the water in the water storage chamber 14 is used up, the manual ball valve on the water inlet pipe 83 can be opened to transport water from the water inlet pipe 83 to the water storage chamber 14, so as to replenish the water storage chamber 14. After the replenishment is completed, the manual ball valve can be closed.

[0029] like Fig.11 As shown, in this embodiment, a thickened portion 851 is provided on the rubber baffle 85. When water flows out from the through hole 84 on the hollow shaft 16, the water squeezes the rubber baffle 85 to deform the rubber baffle 85. The deformation of the rubber baffle 85 corresponding to the thickened portion 851 is smaller, and there is no large deformation at the thickened portion 851. After the rubber baffle 85 is deformed, it is separated from the hollow shaft 16 at the flow channel 853 of the rubber baffle 85. Most of the water flows to the square plate 4 and the partition 6, and a small part of the water flows to the surface of the hollow shaft 16. The firefighting foam liquid adhering to the square plate 4, the partition 6 and the hollow shaft 16 is cleaned by flushing with water.

[0030] like Figure 3 As shown, in this embodiment, a guide strip 21 is fixed to the inner wall of the hollow shaft 16, and the side of the guide strip 21 close to the center circular tube 81 is a curved surface 1. The guide strip 21 is used to guide the water flowing out from the water outlet 82 on the center circular tube 81. When the water is discharged from the water outlet 82 into the hollow shaft 16, it flows toward the through hole 84 under the guidance of the curved surface 1 on the guide strip 21, thereby making the flow of water in the hollow shaft 16 smoother.

[0031] like Figure 8 As shown, in this embodiment, a scraper 9 is fixed on the V-shaped plate 3 at the bottom, and the scraper 9 includes an arc-shaped spring piece 91 fixed on the V-shaped plate 3 at the bottom. The cross section of the arc-shaped spring piece 91 is U-shaped, and the top of the arc-shaped spring piece 91 expands outward. The same inverted V-shaped spring piece 92 is fixed at both ends of the arc-shaped spring piece 91 that expand outward. During the rotation of the partition 6, the scraper 9 is used to scrape the fire foam liquid adhered to the side of the partition 6 away from the hollow shaft 16. The scraper 9 is made of stainless steel and has corrosion resistance. During the rotation of the partition 6, the partition 6 squeezes the arc-shaped spring piece 91 of the scraper 9, so that the arc-shaped spring piece 91 moves inward. At the same time as the deformation, the inverted V-shaped spring piece 92 is driven to deform, and the partition 6 continues to rotate. The side of the partition 6 away from the hollow shaft 16 passes through the connection between the arc-shaped spring piece 91 and the inverted V-shaped spring piece 92, and the fire foam liquid adhering to the side of the partition 6 away from the hollow shaft 16 is scraped off by using the connection between the arc-shaped spring piece 91 and the inverted V-shaped spring piece 92, so that the cleaning of the partition 6 is more comprehensive and thorough. At the same time, when the rubber scraper 5 rotates to the position of the scraper 9, the rubber scraper 5 squeezes the scraper 9 to deform the scraper 9. When the rubber scraper 5 passes through the scraper 9, it can also scrape off the fire foam liquid adhering to the scraper 9, thereby realizing the cleaning of the scraper 9.

[0032] like Figure 8As shown, in this embodiment, a rubber film 18 is connected between the arc-shaped spring piece 91 and the inverted V-shaped spring piece 92. The rubber film 18 is used to seal the two ends of the scraper 9. The rubber film 18 is made of fluororubber and has corrosion resistance. The rubber film 18 is used to prevent the fire foam liquid from entering the interior of the scraper 9.

[0033] like Fig. 9 As shown, in this embodiment, a notch 51 is provided on the side of the rubber scraper 5, and a curved surface 2 is provided on the side of the inner wall of the notch 51. When the rubber scraper 5 rotates to the drain port 13, the fire foam liquid and the water flow are guided by the curved surface 2 at the notch 51 and automatically gather toward the drain port 13, thereby effectively preventing the fire foam liquid and the water flow from accumulating at the bottom of the inner wall of the foam liquid barrel 1.

[0034] like Fig. 9 As shown, in this embodiment, through grooves 7 are provided on the sides of the square plate 4 and the partition 6. Through the design of the through grooves 7, when the square plate 4 and the partition 6 are in a vertical state, the impact of the fire-fighting foam liquid on the square plate 4 and the partition 6 is reduced, thereby improving the service life of the square plate 4 and the partition 6.

[0035] like Fig. 9 As shown, in this embodiment, the inner wall of the through groove 7 is provided with a V-shaped surface. When water flows through the through groove 7, the design of the V-shaped surface reduces the dead angle of water flow, thereby making the cleaning of the firefighting foam liquid adhered to the inner wall of the through groove 7 more comprehensive and thorough.

[0036] Working principle: open the lid at the liquid filling port 12, and then add the fire foam liquid into the foam liquid barrel 1. After the liquid filling is completed, close the lid of the liquid filling port 12, and the foam liquid barrel 1 will store it. When the fire truck 2 is driving, the fire foam liquid will shake in the foam liquid barrel 1. Through the diversion of the arc surface 1 20 and the blocking of the arc surface 2 31, as well as the blocking of the vertical square plate 4 and the partition 6, the impact of the water hammer effect generated during the transportation of the fire foam liquid on the inner wall of the foam liquid barrel 1 is effectively reduced. When extinguishing a fire, open the stop valve at the bottom of the drain port 13, and then start the fire pump of the fire truck 2. The operation of the fire pump causes the fire foam liquid to be drawn out of the foam liquid barrel 1 and sprayed out from the fire water cannon to achieve fire extinguishing. When the fire foam liquid in the foam liquid barrel 1 is used up, the foam liquid barrel 1 needs to be cleaned. During cleaning, the driving mechanism 19 is started. The driving mechanism 19 drives the left hollow shaft 16 to rotate counterclockwise while the other hollow shaft 16 rotates clockwise. The left hollow shaft 16 drives the left square plate 4 and the partition 6 to rotate counterclockwise, and the right hollow shaft 16 drives the right square plate 4 and the partition 6 to rotate clockwise, so that the square plate 4 drives the rubber scraper 5 to scrape off the fire foam liquid adhering to the inner wall of the foam liquid barrel 1 and the V-shaped plate 3; In the process of scraping off the firefighting foam liquid, the water pump 86 is started, and the water pump 86 transports the water in the water storage chamber 14 to the central circular tube 81 through the connecting pipe 17, and then sprays out from the water outlet 82. The sprayed water flows out from the through hole 84 on the hollow shaft 16, and the water flows squeeze the rubber baffle 85 to deform the rubber baffle 85. The deformation of the rubber baffle 85 at the corresponding thickened portion 851 is small, and the deformation at the thickened portion 851 is large. After the rubber baffle 85 is deformed, it is separated from the hollow shaft 16 at the flow channel 853 of the rubber baffle 85. Most of the water flows to the square plate 4 and the partition 6, and a small part of the water flows to the surface of the hollow shaft 16. The firefighting foam liquid adhering to the square plate 4, the partition 6 and the hollow shaft 16 is cleaned by flushing with water. At the same time, during the rotation of the partition 6, the partition 6 squeezes the arc spring piece 91 of the scraper 9, so that the arc spring piece 91 deforms inwardly and drives the inverted V-shaped spring piece 92 to deform. The partition 6 continues to rotate, and the side of the partition 6 away from the hollow shaft 16 passes through the connection between the arc spring piece 91 and the inverted V-shaped spring piece 92. The fire foam liquid adhering to the side of the partition 6 away from the hollow shaft 16 is scraped off by the connection between the arc spring piece 91 and the inverted V-shaped spring piece 92, so that the cleaning of the partition 6 is more comprehensive and thorough. The fire foam liquid scraped off and the water flow generated during the cleaning process flow out from the corresponding drain port 13, and the fire foam liquid and water flow flow along the pipeline to the fire pump position, and the fire pump of the fire truck 2 can be started to spray the fire foam liquid and water flow generated by the cleaning from the fire water cannon position, and it can also achieve a certain cleaning effect on the fire pump, pipeline and fire water cannon.
