the working principle of the water supply system is as follows: before the rocket is launched, whether the pneumatic valve 7, the electric gate valve 17 and the manual gate valve 18 are in a closed state or not is confirmed, and the high-level water tank 1 is filled after the confirmation; for realizing quick water supply to prevent that bottom horizontal main pipe 4 and bleeder 5 from receiving water impact, utilize prefill water installation 2 to fill water pipe 3, bottom horizontal main pipe 4 and bleeder 5 with water in advance, specifically do: firstly, opening a manual gate valve 18 to enable water in the high-level water tank 1 to sequentially pass through an upper vertical pipe, a bypass pipe 19 and a lower vertical pipe, then enter a bottom horizontal main pipe 4 and finally fill a branch pipe 5; at this time, the electric gate valve 17 cannot be opened for water filling, otherwise, huge impact can be caused on the bottom horizontal main pipe 4, the branch pipe 5 and the pneumatic valve 7;
when a pressure gauge 21 in the pre-water filling device 2 monitors that the pipeline is filled with water, the electric valve 17 is opened to enable the whole water supply system to be in a standby state; when the cooling water needs to be sprayed, the pneumatic valve 7 is opened, and the water supply system continuously provides the cooling water for the temperature reduction and noise reduction system.
Further, as shown in fig. 3 and 4, the deflector 13 includes: a stainless steel circular plate 14, a stainless steel circular plate 15 and a stainless steel square plate 16; one end of sixteen stainless steel square plates 16 is uniformly welded on the stainless steel circular plate 15 along the circumferential direction (the sixteen stainless steel square plates 16 are radial on the stainless steel circular plate 15, each stainless steel square plate 16 is arranged along the radial direction of the stainless steel circular plate 15), and the other opposite end is welded on the stainless steel circular plate 14; coaxially butting the end of a stainless steel circular plate 15 of the flow guide device 13 with the water outlet 12 of the high-level water tank 1, and arranging the end of a stainless steel circular plate 14 in the high-level water tank 1 to enable water to flow to the water outlet 12 of the high-level water tank 1 through the side surface of the flow guide device 13; wherein, the outer diameter of the stainless steel circular plate 15 is equal to the diameter of the stainless steel circular plate 14, and the inner diameter is equal to the diameter of the water outlet 12 of the high-level water tank 1; the outer diameter of the stainless steel circular ring plate 15 is 500-800 mm larger than the inner diameter, namely the radial width of the stainless steel circular ring plate 15 is 500-800 mm; the side length of one end of the sixteen stainless steel square plates 16 welded on the stainless steel circular ring plate 15 is equal to the radial width of the stainless steel circular ring plate 15, and the side length of the other end perpendicular to the side length is 500-800 mm;

further, the thicknesses of the stainless steel circular plate 14, the stainless steel circular ring plate 15 and the stainless steel square plate 16 are respectively 5mm, so as to ensure the structural strength of the flow guide device 13;
furthermore, the number of the branch pipes 5 on each side of the horizontal longitudinal pipe in the bottom horizontal main pipe 4 and the pipe diameter of each branch pipe 5 are determined by the water demand of the emission platform cooling and noise reducing system;
further, the drift diameter of the electric gate valve 17 is the same as the pipe diameter of the water conveying pipe 3;
furthermore, the water delivery vertical pipe 3 and the bottom horizontal main pipe 4 are both metal pipes;
furthermore, the rocket launching interval is often longer, the water delivery vertical pipe 3 and the bottom horizontal main pipe 4 are in an emptying state in the rocket launching interval time, and the metal pipeline is often switched alternately between a water filling state and an emptying state, so that the surface corrosion inside the metal pipeline is very easily caused (an anticorrosive coating on the inner surface of the pipeline has the phenomenon of bubbling and even falling off); when the system supplies water, the fallen anticorrosive material can cause the blockage of the pneumatic valve 7 on the branch pipe 5, and the system operation is influenced; as shown in fig. 6, more than two steel crawling ladders 22 are axially arranged on the inner wall surface of the lower vertical pipe in the water conveying pipe 3, so that a maintainer can periodically overhaul the inside of the pipeline, and when the overhaul is needed, the maintainer opens the flange blind plate 6 and enters the inside of the pipeline for overhaul;
furthermore, the high-level water tank 1 is formed by welding stainless steel plates, and is also connected with a water replenishing pipe 8, a water drain pipe 9 and an overflow pipe 10; wherein, the water replenishing pipe 8 is used for externally replenishing water to the high-level water tank 1; in the rocket launching gap, an electric gate valve 17 and a manual gate valve 18 in the pre-filling device 2 are closed, the water drain pipe 9 is used for completely draining the residual water in the high-level water tank 1, and at the moment, the high-level water tank 1 can be used as a fire-fighting tank or a domestic water tank of a service tower; the overflow pipe 10 serves to prevent the water level in the high-level tank 1 from being higher than a set value.
