step two: after the two arc-shaped fixing plates A10 clamp and fix the fire hydrant, the air pump 7 continuously conveys outside air to the hydraulic tank 13, so that the purified liquid in the hydraulic tank 13 is continuously input into the strip-shaped sealing box 11, the piston 43 continuously moves, then the right-angle block A48 and the right-angle block B54 are in contact with the trapezoidal block 45, and the right-angle block A48 and the right-angle block B54 respectively move downwards and upwards in the rectangular groove, so that the liquid guide hole C55 is communicated with the L-shaped liquid guide groove 61, and meanwhile, the liquid guide hole A58 is communicated with the liquid guide hole B57, so that the pressure of the strip-shaped sealing box 11 is relieved;
step three: then, the flange plate is placed in the circular fixed disk 5, the electric telescopic rod 41 is opened, the arc-shaped fixed plate B42 is driven to move through the expansion and contraction of the movable end of the electric telescopic rod 41, so that the flange plate is fixed, wherein the expansion and contraction speeds of the electric telescopic rod 41 are the same, so that the moving speed of the arc-shaped fixed plate B42 is the same, the flange plate is conveniently fixed in the middle of the circular fixed disk 5, the center of the flange plate is collinear with the center of a fire hydrant, the flange plate is conveniently and accurately connected with the fire hydrant, the dislocation of the flange plate and the fire hydrant is avoided, and the connection of the flange plate and the fire hydrant is facilitated; then the hydraulic cylinder 3 is opened, the round fixing disc 5 is driven to move by the expansion of the hydraulic cylinder 3, so that the flange plate moves downwards, and finally the flange plate is connected with the fire hydrant;
step four: then, welding the joint of the flange plate and the fire hydrant by using a spot welding machine, wherein smoke is generated during welding, and the air in the annular air guide pipe 9 is extracted by the air extractor 7, so that the external smoke enters the annular air guide pipe 9 through the air inlet hole 50 at the top of the annular air guide pipe 9, the smoke is conveyed to the bottom in the hydraulic tank 13 through the air inlet pipe B8, and the smoke moves in the purifying liquid under the action of the partition plate 15, so that the flow path of the smoke in the purifying liquid is enlarged, the harmful substances in the smoke can be conveniently and effectively purified, and the purifying work efficiency is improved;
step five: when the pressure intensity of the strip-shaped seal box 11 is greater than the elastic force of the extrusion spring B60, the clamping block 59 is abutted into the clamping groove 46, the piston 43 is limited, the piston 43 is prevented from moving when the strip-shaped seal box 11 is decompressed, so that the fire hydrant is stably clamped, and when the pressure intensity is reduced, the clamping block 59 is reset under the action of the extrusion spring B60, and the clamping block 59 is separated from the clamping groove 46; meanwhile, the purifying liquid on one side of the strip-shaped sealing box 11 flows into the other side of the strip-shaped sealing box 11 through the liquid guide hole C55, the L-shaped liquid guide groove 61, the liquid guide hole A58 and the liquid guide hole B57, and finally enters the circular cylinder 30 through the liquid guide pipe 23, when the purifying liquid falls on the turbine 24 in the circular cylinder 30, the turbine 24 is driven to rotate, the purifying liquid falls on the bottom in the circular cylinder 30, then the purifying liquid enters the liquid outlet pipe 14, and finally the purifying liquid is sprayed out from the spray head on the outer wall of the liquid outlet pipe 14, so that the air is sprayed, harmful substances in the air can be conveniently removed, and the harmful substances in the air can be further effectively removed;
step six: when the turbine 24 rotates, the rotating shaft 25 is driven to rotate, and then the bevel gear A28 is driven to rotate, so that the bevel gear B29 is driven to rotate, the connecting shaft B22 is further driven to rotate, the movable shaft B35 and the movable shaft A33 are driven to rotate through the rotation of the connecting shaft B22, and then the connecting shaft A21 is driven to rotate, so that the circular disc B20 is driven to rotate, when the arc-shaped opening 37 on the circular disc B20 is overlapped with the circular hole 38, gas in the hydraulic tank 13 flows out, the pressure of the hydraulic tank 13 is conveniently relieved, the hydraulic tank 13 is prevented from being damaged due to overlarge pressure in the hydraulic tank 13, and the service life of the hydraulic tank 13 is prolonged;
step seven: after welding is finished, the handle 34 is pushed, so that the limiting strip B36 on the outer wall of the movable shaft B35 is separated from the limiting groove A, the connection between the movable shaft B35 and the connecting shaft B22 is released, then the handle 34 is rotated to drive the connecting shaft A21, so that the circular disc B20 is driven to rotate, and when the arc-shaped opening 37 on the circular disc B20 is overlapped with the circular hole 38, gas in the hydraulic tank 13 flows out; then under the action of the return spring B51 and the return spring C52, the arc-shaped fixing plate A10 is loosened from the fire hydrant, so that the fire hydrant is convenient to take.
