[0021] Embodiment

[0022] Given by Figures 1-3 is a fireproof rolling shutter door with good fireproof effect, including a fireproof rolling shutter door body 1. The fireproof rolling shutter door body 1 includes a storage seat for storing the rolling shutter, and a frame box 2 is arranged on the upper end surface of the storage seat; a spraying assembly 5 is assembled and arranged in the frame box 2;

[0023] The spraying assembly 5 includes a bearing seat 51 disposed inside the frame box 2. A threaded lead screw 53 is rotatably provided inside the bearing seat 51. An external meshing of the threaded lead screw 53 is provided with a sliding shaft seat 54. An outer sleeve of the sliding shaft seat 54 is provided with a sleeve seat 55. Both sides of the sleeve seat 55 are installed with connecting pipes 56. A nozzle 57 is communicated and provided on the connecting pipe 56; Spraying hoses 510 are communicated and provided on both of the two connecting pipes 56.

[0024] In this embodiment, compared with the fireproof rolling shutter door in the cited document, by spraying the fire fighting water in the present application, it is possible to prevent the fire from spreading through the gaps or voids above the fireproof rolling shutter door body 1, thereby enhancing the fireproof isolation effect and improving the overall fireproof performance of the fireproof rolling shutter door body 1. The spraying of the fire fighting water can also reduce the temperature in the fire area and slow down the spreading speed of the fire; Through the reciprocating spraying of the nozzle 57, a water curtain can be formed above the fireproof rolling shutter door body 1 by spraying the fire fighting water, thereby preventing the fire from spreading through the gaps or voids above the fireproof rolling shutter door body 1, and further improving the overall fireproof performance of the fireproof rolling shutter door body 1.

[0025] Specifically, referring to Figures 2-3 , elbows 59 are communicated and provided at the ends of both of the two spraying hoses 510. The spraying hoses 510 are gooseneck tubes.

[0026] In this embodiment, the elbows 59 provided can be used to transfer the fire fighting water in the fire fighting water tank 4, and then conduct the fire fighting water into the spraying hoses 510 to achieve spraying and extinguishing of the fire. The elbows 59 provided are gooseneck hoses. In actual use, the gooseneck hoses provided have good flexibility and bendability, and can conveniently adjust the spraying direction and extension distance, thereby realizing the radial movement on the upper end face of the fireproof rolling shutter door body 1.

[0027] It should be noted that when using the spraying hoses 510 for reciprocating spraying, it is necessary to ensure that the connection and fixation of the hoses are firm and reliable to avoid water leakage or hose detachment during the spraying process; In addition, the service life and maintenance of the spraying hoses 510 also need to be regularly inspected and replaced to ensure their normal operation and spraying effect.

[0028] Specifically, referring to Figures 1-2 , a fire fighting water tank 4 is assembled and provided on the upper end face of the frame box 2. A water inlet 41 is communicated and provided on the fire fighting water tank 4. A water outlet hole is opened at the bottom of the fire fighting water tank 4; A pump is also provided inside the frame box 2. The input end of the pump is communicated with the fire fighting water tank 4 through a conduit, and the output end of the pump is communicated with the elbow 59 through a conduit.

[0029] In this embodiment, during actual use, the user can pour fire-fighting water into the fire-fighting water tank 4 through the water inlet 41. At this time, through the operation of the pump, the fire-fighting water poured into the fire-fighting water tank 4 can be discharged from the output end of the pump, and at the same time, it is transmitted through the elbow 59 to the spray hose 510. Through the connection between the spray hose 510 and the connecting pipe 56, finally, the fire-fighting water in the fire-fighting water tank 4 can be sprayed out through the nozzle 57. Through the spraying of the fire-fighting water by the nozzle 57, the spraying fire extinguishing of the rolling shutter door panel is finally realized, thereby improving the fire prevention effect of the fire-proof rolling shutter door body 1.

[0030] Specifically, referring to Figures 2-3 , a reciprocating motor 52 is also assembled inside the frame box 2, and the output end of the reciprocating motor 52 is connected to the threaded lead screw 53; a bearing member is arranged inside the bearing seat 51, and the threaded lead screw 53 is rotationally matched with the bearing member. A control switch 3 is arranged outside the fire-proof rolling shutter door body 1, and the control switch 3 is electrically connected to the reciprocating motor 52 and the pump.

[0031] In this embodiment, during use, when the control switch 3 controls the start and stop of the reciprocating motor 52, at this time, through the start of the reciprocating motor 52, the set reciprocating motor 52 can drive the threaded lead screw 53 to rotate. At the same time, the bearing arranged in the bearing seat 51 can ensure the stable rotation of the threaded lead screw 53. The set control switch 3 can also be electrically connected to the pump in the frame box 2, thereby realizing the start and stop control of the pump. In order to prevent the set control switch 3 from being difficult for the user to control safely in case of a fire, in a preferred embodiment, the installation position of the set control switch 3 is not limited to being installed on the fire-proof rolling shutter door body 1, thereby realizing the user's safe control operation of the control switch 3.

[0032] Furthermore, the remote power connection method of the control switch 3, the pump, and the reciprocating motor 52 is prior art, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the field. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0033] It should be noted that the bearing member in the set bearing seat 51 can ensure the rotation stability of 73. The rotational cooperation between 73 and the bearing can provide a relatively high load-bearing capacity, and the design and selection of the bearing can be selected according to actual needs to meet the required load-bearing capacity, thereby making 73 stable during rotation.

[0034] Specifically, referring to Figures 2-3 , an installation block 58 is arranged on each side of the reciprocating motor 52, and the installation block 58 is sleeved outside the connection part of the spray hose 510 and the elbow 59.

[0035] In this embodiment, the provided mounting block 58 can be used to protect the connection between the spray hose 510 and the elbow pipe 59, thereby preventing the spray hose 510 from falling off during movement. Meanwhile, in a preferred embodiment, a rubber gasket can be provided inside the mounting block 58 to further ensure the connection tightness between the spray hose 510 and the elbow pipe 59.

[0036] Specifically, referring to Figures 2-3 , two side rods 511 are further provided between the bearing seat 51 and the reciprocating motor 52. The two side rods 511 are respectively arranged on one side of the threaded lead screw 53, and both two side rods 511 penetrate through the sliding shaft seat 54.

[0037] In this embodiment, by cooperating with the two side rods 511 to limit the sliding shaft seat 54, when the threaded lead screw 53 is driven by the reciprocating motor 52 to rotate, the provided sliding shaft seat 54 can drive the sleeve seat 55 and the connecting pipe 56 to move linearly along the outside of the threaded lead screw 53. The radial movement of the provided sleeve seat 55 can drive the connecting pipe 56 and the nozzle 57 to move linearly along the stroke range of the threaded lead screw 53, so as to realize the reciprocating spray extinguishing of the fireproof rolling shutter door body 1.

At this time, through the operation of the pump, the fire water filled in the fire water tank 4 can be discharged through the pump, and at the same time, it is transmitted to the spray hose 510 through the elbow pipe 59. Through the connection between the spray hose 510 and the connecting pipe 56, finally, the fire water in the fire water tank 4 can be sprayed out through the nozzle 57. Through the spraying of the fire water by the nozzle 57, the spraying extinguishing of the rolling shutter panel is finally realized, thereby improving the fireproof effect of the fireproof rolling shutter door body 1;

[0040] The second step: When the control switch 3 controls the start and stop of the spray assembly 5, at this time, by starting the reciprocating motor 52, the provided reciprocating motor 52 can drive the threaded lead screw 53 to rotate. At this time, by cooperating with the two side rods 511 to limit the sliding shaft seat 54, finally, the provided sliding shaft seat 54 can drive the sleeve seat 55 and the connecting pipe 56 to move linearly along the outside of the threaded lead screw 53.
