Their main functions are to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. In the prior art, fire hydrant equipment generally uses emergency water sources for water supply. Although the water pressure of emergency water sources is greater than that of daily water, when the disaster relief point is far away or high, a higher water pressure is required for rescue operations. However, the existing fire hydrant equipment is not equipped with a pumping and pressurizing device, and it is impossible to perform pumping and pressurizing operations, and it is impossible to better perform rescue and disaster relief operations on high or distant fire points.

[0020] In this embodiment, the first output shaft 8 is movably arranged inside the fire hydrant body 1, the thread is arranged on the outer wall at the top of the first output shaft 8, sliders 16 are symmetrically fixedly arranged at both ends of the adjusting plate 10, and sliding grooves are symmetrically opened on the inner wall at the top of the fire hydrant body 1, and the sliders 16 are slidably installed inside the sliding grooves, and the spring 11 is fixedly installed between the top of the adjusting plate 10 and the bottom of the fixed box 5, and the spring 11 is sleeved on the outer side of the first output shaft 8. Fixed rods 12 are symmetrically fixedly installed on both sides of the bottom of the adjusting plate 10, and a valve plate 13 is fixedly installed at the bottom end of the fixed rod 12, and the valve plate 13 is slidably installed on the bottom end of the first output shaft 8, and a sealing rubber ring is arranged between the valve plate 13 and the first output shaft 8, and a fixing ring 1 is fixedly arranged on the inner wall of the fire hydrant body 1 corresponding to the bottom of the valve plate 13 4. The fixing ring 14 is arranged on the outside of the first output shaft 8. Water outlets 3 are symmetrically opened on both sides of the top of the fire hydrant body 1. The outer ends of the water outlets 3 are screwed to install covers 4. The water outlets 3 are arranged on both sides of the valve plate 13. The bottom end of the fire hydrant body 1 is provided with a flange 2. When the first output shaft 8 rotates, it can drive the adjusting plate 10 through the thread. Due to the limitation of the slide groove and the slider 16, the adjusting plate 10 moves upward inside the fire hydrant body 1. At the same time, the adjusting plate 10 drives the valve plate 13 through the fixing rod 12. The valve plate 13 is separated from the fixing ring 14, so that the water outlet 3 is connected with the bottom end of the fire hydrant body 1.

[0022] When the fire hydrant pumping and boosting device is used, the fire hydrant body 1 is fixedly connected to the emergency water supply pipeline through the flange 2 at its bottom end. At this time, the valve plate 13 is squeezed and contacted with the fixing ring 14, and the fire hydrant body 1 is in an inactive state. When performing disaster relief in a nearby or lower position, the rubber cover 6 is pulled out, and the second output shaft 9 is rotated with a wrench. The second output shaft 9 drives the first output shaft 8 to rotate through the dual-axis motor 7. The first output shaft 8 drives the adjusting plate 10 through the thread. Under the limit of the slider 16 and the slide groove, the adjusting plate 10 moves upward and compresses the spring 11. The adjusting plate 10 simultaneously drives the fixing rod 12 and the valve plate 13, so that the valve plate 13 is separated from the fixing ring 14, which is convenient for the water outlet 3 to be connected with the water outlet 3. The bottom end of the fire hydrant body 1 is connected, which is convenient for manual starting of the fire hydrant body 1. The rubber cover 6 can increase the protection of the second output shaft 9; when disaster relief is needed at a fire point far away or at a high place, first manually rotate the second output shaft 9, manually adjust the adjustment plate 10 and the valve plate 13 upward, and after the adjustment is completed, energize the dual-axis motor 7, and the dual-axis motor 7 starts and drives the first output shaft 8 and the second output shaft 9 to rotate at the same time, and the first output shaft 8 drives the impeller 15 to rotate, so that the water source inside the fire hydrant body 1 is accelerated to flow to the water outlet 3 and discharged from the water outlet 3, thereby increasing the water pumping and pressurizing capacity of the fire hydrant body 1, and facilitating disaster relief operations at fire points high or far away.
