Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, for the utility model discloses a fire prevention rolling slats door's bottom seal structure, fire prevention rolling slats door is including installing box 1 on door opening (not shown in the figure) top wall body, and 1 level of box sets up, rotates along its length direction in the box 1 and is provided with the reel (not shown in the figure), and it has fire prevention roll of shutter 2 to coil on the reel. Two guide rails 3 which are vertically arranged are fixed on two side walls of the door opening, and two sides of the fireproof roller shutter 2 in the width direction are respectively arranged in the two guide rails 3 in a sliding manner. Seal groove 4 has been seted up on subaerial under guide rail 3, and seal groove 4 sets up along the width direction of fire prevention roll of curtain 2, and the lower extreme of guide rail 3 flushes with the notch of seal groove 4. Be provided with seal assembly 5 in the seal groove 4, seal assembly 5 includes the water tank 51 with seal groove 4 intercommunication, and water tank 51 and seal groove 4 intercommunication department are provided with opening and close valve 54, are equipped with the controlling means who controls opening and close valve 54 between seal groove 4 and the fire-proof roll screen 2.

Referring to fig. 1 and 2, two placing cavities (not shown in the figure) are formed in the wall body at the two ends of the sealing groove 4 at the bottom of the door opening, the placing cavities are used for placing a water tank 51, the bottom of the water tank 51 is flush with the bottom of the sealing groove 4, and a sealing plate 52 is arranged between the placing cavities and the sealing groove 4. The water tank 51 is provided with a water outlet pipe 53 for injecting water in the water tank 51 into the sealing groove 4, the water outlet pipe 53 penetrates through the sealing plate 52 to be communicated with the sealing groove 4, the connection part of the peripheral wall of the water outlet pipe 53 and the sealing plate 52 is sealed, and the opening and closing valve 54 is arranged at one end of the water outlet pipe 53, which is positioned in the sealing groove 4.

Referring to fig. 2, the on-off valves 54 are hand wheel valves, the hand wheels of the two on-off valves 54 are respectively located on two sides of the lifting direction of the fire-proof rolling screen 2, the hand wheels of the on-off valves 54 are vertically arranged, and the axial lines of the hand wheels are perpendicular to the length direction of the sealing groove 4. The control device comprises a gear 55 and a rack 56, wherein the gear 55 is coaxially and fixedly connected with a hand wheel of the opening and closing valve 54, the rack 56 is fixedly arranged on the fireproof rolling screen 2 and is meshed with the gear 55 in a matching manner, the gear 55 is coaxially sleeved on the peripheral wall of the hand wheel of the opening and closing valve 54, and the rack 56 is vertically arranged on the side walls of the two sides of the lower end of the fireproof rolling screen 2 along the lifting direction. When the fire-proof rolling shutter 2 descends into the sealing groove 4, the gear 55 is meshed with the rack 56, the fire-proof rolling shutter 2 descends continuously, and the gear 55 is driven by the rack 56 to rotate so as to open the opening and closing valve 54. The surface of water in the water tank 51 is located the outlet pipe 53 top, makes the water injection seal groove 4 of storing in the water tank 51, and the surface of water height that the water tank 51 pours into the water in seal groove 4 is higher than the height at the bottom of the seal groove 4 of 2 bottom ends of fire prevention rolling screen, realizes sealed effect.

Referring to fig. 3 and 4, a baffle 6 for covering the sealing groove 4 is rotatably disposed at the notch of the sealing groove 4, so as to prevent the fire-proof rolling shutter 2 from completely falling down when a fire disaster occurs due to the foreign matter falling into the sealing groove 4. Baffle 6 length is the same with the width of fire prevention roll-up 2 and baffle 6 width slightly is lighter than the width of

seal groove

4, and 6 length direction's of baffle one side is rotated through the hinge and is set up on seal groove 4 along its length direction's one side lateral wall, and baffle 6 can be to the upset in the seal groove 4. Six vertical accommodating grooves 71 are formed in the side wall, hinged to the baffle 6, of the sealing groove 4, the six accommodating grooves 71 are formed at equal intervals along the length direction of the sealing groove 4, the telescopic supporting rod 7 is rotatably arranged in the accommodating grooves 71, and the other end of the supporting rod 7 is rotatably connected to the bottom surface of the baffle 6. The bracing piece 7 includes one connecting rod 72 articulated with baffle 6 and articulates in two connecting rods 73 of holding tank 71 diapire, and the cavity that runs through is seted up along its axial to the one end that baffle 6 was kept away from to one connecting rod 72, and the diameter of cavity is greater than the diameter of two connecting rods 73, and the one end of two connecting rods 73 articulates in the bottom of holding tank 71, and the other end slides and pegs graft in the cavity of one connecting rod 72. The opening of the cavity extends inwards to form a first limiting ring 74, the inner diameter of the first limiting ring 74 is the same as the diameter of the second connecting rod 73, a second limiting ring 75 is arranged on the outer peripheral wall of the end part of the second connecting rod 73, which is located in the cavity, and the outer diameter of the second limiting ring 75 is larger than the inner diameter of the first limiting ring 74. One end that connecting rod one 72 and connecting rod two 73 kept away from each other is fixed respectively on the lateral wall and is provided with two solid fixed rings 76, and the cover is equipped with reset spring 77 that is located between two solid fixed rings 76 on connecting rod one 72 and the connecting rod two 73, and reset spring 77's both ends respectively with two solid fixed rings 76 butt. When the return spring 77 is in a natural state, the first connecting rod 72 and the second connecting rod 73 slide relatively until the first limiting block abuts against the second limiting block, the support rod 7 extends to the longest, and the baffle 6 is in a horizontal position at the moment; when the support rod 7 is contracted to the shortest, the baffle 6 rotates downwards to the largest angle, and the fireproof rolling curtain 2 descends to the lowest position.

The implementation principle of the embodiment is as follows: when a fire disaster does not happen, the return spring 77 is in a natural state, the support rod 7 is stretched to the longest, and the baffle 6 is in a horizontal position at the moment, so that sundries are prevented from falling into the sealing groove 4; when the conflagration takes place, separate the space of catching a fire and safe space through alarm system control fire prevention roll screen 2 decline, fire prevention roll screen 2 pushes down baffle 6, and reset spring 77 is compressed, and bracing piece 7 contracts, and when fire prevention roll screen 2 descends to the extreme lower position, bracing piece 7 contracts to the shortest, and 6 down turned angle of baffle this moment are the biggest. In the descending process of the fireproof rolling shutter 2, the rack 56 on the fireproof rolling shutter 2 drives the gear 55 on the opening and closing valve 54 to rotate to open the valve, and water stored in the water tank 51 is injected into the sealing groove 4 through the water outlet pipe 53 until the water surface height in the sealing groove 4 is higher than the height of the bottom of the fireproof rolling shutter 2, namely the bottom sealing effect of the fireproof rolling shutter is realized.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
