The purpose of this utility model is at the above problem, provides a kind of structure simple as far as possible, can guarantee the Smoke proofing and fire proofing roller blind device of normal function simultaneously.
The purpose of this utility model is achieved in that the utility model comprises lodge, rotating shaft, roller shutter and guide groove, lodge is positioned at top of guide slot, in lodge, roller shutter is wound in the rotating shaft by bearing fixing in rotating shaft, and roller shutter can be along guide groove movement, roller shutter is that lightweight material is made, its lower end is provided with pouring weight, and after roller shutter wound up, its below was by the Electromagnetic bolt support, Electromagnetic bolt is fixed in the lodge, and Electromagnetic bolt links to each other with control circuit; The utility model also is provided with life saving system, comprises life line, line tube and rope sheave, and rope sheave is axle with the rotating shaft and fixedlys connected with rotating shaft, one end of life line is fixed in the lower end of roller shutter, the line tube is passed for one section in the middle part, is fixed on the rope sheave in the other end, and the line tube is fixed in the lodge.When fire took place, dense smoke or high temperature triggered Electromagnetic bolt and open, and roller shutter puts down along guide groove rapidly under the action of gravity of weight, and when roller shutter rotated, the rope sheave of fixedlying connected with rotating shaft rotated synchronously, makes a part of life line around last rope sheave; When desiring to make roller shutter again around last rotating shaft when escape or under the normal condition, as long as down tear life line.
Technique effect of the present utility model is: 1. the utility model adopts the lightweight material of lower end band weight to replace expensive and thick and heavy rewindable metal curtain, and the putting down and roll and need not Electric Machine Control of roller shutter, so the utlity model has simple in structure and the low advantage of cost; 2. the utility model has also designed life saving system, and is reasonable in design, simple in structure feasible.3. the utility model utilizes the design of frame for movement itself to realize function as far as possible, and dependence is automatically controlled with exceeding, can avoid like this can not working because of factors such as accident power-off make it.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model embodiment.
As shown in Figure 1, the utility model embodiment comprises lodge 1, rotating shaft 2, roller shutter 3, guide groove 4, Electromagnetic bolt 5, sparge pipe 11, control circuit and life saving system.Lodge 1 is positioned at guide groove 4 tops, and rotating shaft 2 is fixed in the lodge 1 by bearing 6; One end of roller shutter 3 is fixed in the rotating shaft 2, and remainder is wound in the rotating shaft 2, and roller shutter 3 can move along guide groove 4, and roller shutter 3 is made for canvas, and the lower edge of roller shutter 3 is fixed with bar shaped band steel 7 as weight, and roller shutter 3 can fall under the action of gravity of band steel 7 automatically; After roller shutter 3 wound up, its below was by Electromagnetic bolt 5 supports, and Electromagnetic bolt 5 is fixed in the lodge 1, and Electromagnetic bolt 5 links to each other with control circuit.Sparge pipe 11 is fixed in the lodge 1, sparge pipe 11 is positioned at a side of roller shutter 3 and nestles up roller shutter 3, the one end sealing of sparge pipe 11, the other end passes to outside the lodge 1, during installation the water pipe of sparge pipe 11 and fire-fighting connected and get final product, sparge pipe 11 is provided with hole for water spraying, and hole for water spraying is offered towards the direction of roller shutter 3, also is provided with the electromagnetism water valve 12 that links to each other with control circuit on sparge pipe 11.The control circuit of present embodiment is cigarette sense or temperature sense control circuit, promptly be provided with cigarette dependent sensor and temperature pick up in parallel, thereby dense smoke or high temperature all can trigger the unlatching of this control circuit control Electromagnetic bolt 5 and electromagnetism water valve 12; The utility model also is provided with manual stay cord and is connected with electromagnetism water valve 12 with Electromagnetic bolt 5 simultaneously and provides against any contingency, promptly when control circuit can not be worked, spur manual stay cord and Electromagnetic bolt 5 and electromagnetism water valve 12 are opened roller shutter 3 is put down and made sparge pipe 11 towards roller shutter 3 water sprays; The utility model also is provided with life saving system, comprise life line 8, line tube 9 and rope sheave 10, rope sheave 10 serves as axle with rotating shaft 2 and fixedlys connected with rotating shaft 2, one end of life line 8 is fixed in the lower end of roller shutter 3, the middle part is passed line tube 9 and is reserved one section in line tube 9 for one section, life line 8 is fixed on the rope sheave 10 in the other end, line tube 9 is fixed in the lodge 1, life line 8 state as shown in Figure 1 under normal condition, and dense smoke or high temperature fall roller shutter 3 to drive rotating shaft 2 and rotate when the condition of a disaster takes place, the roller shutter 3 lower end bands a part of life line 8 in the tube 9 that rolls off the production line on the one hand, the rope sheave 10 of fixedlying connected with rotating shaft 2 rotates synchronously on the one hand, make a part of life line 8 in the line tube 9 up around last rope sheave 10, when escaping, the people desire to make roller shutter 3 so again when last rotating shaft 2, as long as down tear life line 8, the process that falls with roller shutter 3 in this process is opposite basically; When with Electromagnetic bolt 5 unlatchings roller shutter 3 being fallen, electromagnetism water valve 12 is opened simultaneously, and water sprays to roller shutter 3 by the hole for water spraying on the sparge pipe 11, and water flows down along roller shutter 3, and flameproof effect is strengthened greatly.
