[0037] As shown in Figures 1-12 , a ship railing type water spraying fire extinguishing system includes a rotating nozzle member, a nozzle rotation transmission member, and a nozzle rotation power member. The rotating nozzle member, the nozzle rotation transmission member, and the nozzle rotation power member are all arranged on the railing 1 of the ship. Further, the pull rod is in a hollow tubular shape. The rotating nozzle member includes a rotating support member and a rotating spraying member. The rotating support member is arranged on the railing 1, and the rotating spraying member is arranged on the rotating support member.

[0038] The rotating support member includes a relay pipe 3 and a rotating support base. One end of the relay pipe 3 penetrates into the railing 1 so that the relay pipe 3 is in communication with the inside of the railing 1. The rotating support base includes a first rotating support base 4 and a second rotating support base 5. The first rotating support base 4 and the second rotating support base 5 are both arranged on the railing 1. The first rotating support base 4 is in a spherical crown shape, and an installation through hole is provided on the first rotating support base 4. The diameter of the installation through hole is not less than the diameter of the railing 1, and the axis of the installation through hole coincides with the center of the sphere of the first rotating support base 4. The first rotating support base 4 is fixedly sleeved on the railing 1 through the installation through hole, and the bottom surface of the first rotating support base 4 is attached to the side wall of the relay pipe 3. The second rotating support base 5 has the same structure as the first rotating support base 4.

At the same time, the center of the sphere of the second rotating support base 5 coincides with the center of the sphere of the first rotating support base 4.

[0039] The rotating spraying member includes a rotating spraying seat 6 and a spraying head 7. The rotating spraying seat 6 is in a spherical ring shape. The inner spherical radius of the rotating spraying seat 6 is the same as the spherical radius of the first rotating support base 4. A flow relay groove is provided on the inner spherical surface of the rotating spraying seat 6. The flow relay groove is in an annular groove shape, and the axis of the flow relay groove coincides with the axis of the rotating spraying seat 6. The two ends of the rotating spraying seat 6 are rotationally and cooperatively sleeved on the spherical surfaces of the first rotating support base 4 and the second rotating support base 5 one by one, so that the rotating spraying seat 6 can rotate in any direction on the first rotating support base 4 and the second rotating support base 5, thereby controlling the direction of the water flow or water mist sprayed by the spraying head 7 and improving the fire extinguishing efficiency. The spraying head 7 is embedded in the spraying through hole on the rotating spraying seat 6 so that the spraying head 7 is in communication with the flow relay groove. As an option, the spraying head 7 is one or a combination of a water nozzle, a sprinkler head, a water spray nozzle, or a water curtain nozzle.

[0040] Further, a first sliding sealing ring 8 is provided on the top surface of one side wall of the flow relay tank, and a second sliding sealing ring 9 is provided on the top surface of the other side wall of the flow relay tank.

[0041] It should be noted that the water pump injects water flow with a predetermined pressure into the railing 1 through the relay inlet pipe. The water flow passes through the railing 1 and flows out from the relay pipe 3 into the space between the first rotating support seat 4 and the second rotating support seat 5, then the water flow enters the flow relay tank, and finally sprays outwards from the spray head 7.

[0042] Further, multiple sets of the rotating spray head members are provided, and the multiple sets of the rotating spray head members are uniformly distributed on the railing 1 at a predetermined interval.

[0044] The rotating transmission member includes a rotating transmission wheel 12, a magnetic coil, and a return spring 13. The rotating transmission wheel 12 and the return spring 13 are both arranged on the transmission shaft 11, and the magnetic coil is arranged on the rotating transmission wheel 12. The rotating transmission wheel 12 is in the shape of a curved surface wheel, and the outer curved surface radius of the rotating transmission wheel 12 is the same as the outer spherical surface radius of the rotating injection seat 6. Further, a rotating through hole is arranged on the rotating transmission wheel 12, and the rotating transmission wheel 12 is slidably sleeved on the transmission shaft 11 through the rotating through hole. The outer curved surface of the rotating transmission wheel 12 is in circumferential transmission cooperation with the outer spherical surface of the rotating injection seat 6. At the same time, the slider on the inner wall of the rotating through hole is in cooperation with the chute on the outer wall of the transmission shaft 11, so that the rotating transmission wheel 12 is circumferentially locked and axially slidable on the transmission shaft 11. It should be noted that the outer curved surface of the rotating transmission wheel 12 and the outer spherical surface of the rotating injection seat 6 are in frictional transmission or meshing transmission, so as to adjust the injection of the injection head 7 at any angle along the transverse plane of the ship. When the outer curved surface of the rotating transmission wheel 12 and the outer spherical surface of the rotating injection seat 6 are in meshing transmission, a first set of teeth is arranged on the outer spherical surface of the rotating injection seat 6, and the first set of teeth follows the curvature direction of the outer spherical surface of the rotating injection seat 6.

A plurality of the second set of teeth are evenly distributed circumferentially around the rotating transmission wheel 12, and the second set of teeth is meshed with the first set of teeth.

[0045] The magnetic coil is fixedly embedded in the spiral groove in the rotating through hole. When direct current is passed through the magnetic coil to generate a magnetic field, it will push the rotating transmission wheel 12 to slide back and forth axially on the transmission shaft 11. The axially sliding rotating transmission wheel 12 axially pushes the rotating injection seat 6 to slide circumferentially and seal around the center on the rotating support seat, and finally adjusts the injection head 7 to swing back and forth at any angle along the longitudinal plane of the ship, so as to change the injection direction of the injection head 7. The return spring 13 is sleeved on the transmission shaft 11, and one end of the return spring 13 is connected to one end of the rotating transmission wheel 12, and the other end of the return spring 13 is fixedly connected to the transmission shaft 11. The two return springs 13 are distributed one by one corresponding to both ends of the rotating transmission wheel 12. When the magnetic coil stops passing current, it will push the rotating transmission wheel 12 to reset, so as to promote the reset of the injection head 7.

[0046] A plurality of sets of the rotating transmission members are provided, and the plurality of sets of rotating transmission members correspond to the plurality of sets of rotating nozzle members one by one.

[0047] The nozzle rotation power component includes a worm gear 14, a motor 15 and a worm 16. The worm gear 14 is fixedly sleeved on the transmission shaft 11.
