As shown in fig. 1, a building 1 is provided with an integrated manual-automatic intelligent smoke and heat exhausting system, which includes a control system and a smoke exhausting device. Specifically, the upper part of the side wall of the building 1 is provided with a window opening for arranging a smoke exhaust device. The smoke evacuation device comprises a fixed sash 2 and a movable window 3. The fixed window frame 2 is arranged in the window opening and fixedly connected with the side wall. The movable window 3 is provided in the fixed window frame 2 and is movable relative to the fixed window frame 2. The movable window 3 has a closed position and an open position. When the movable window 3 is located at the closed position, the movable window 3 is flush with the fixed window frame 2, so that the inner and outer spaces (i.e., indoor and outdoor) of the side wall of the building 1 are not communicated through the window hole. When the movable window 3 is located at the open position, the movable window 3 and the fixed window frame 2 are arranged at an angle, so that an opening is formed between the movable window 3 and the fixed window frame 2, and the inner space and the outer space of the side wall of the building 1 can be communicated through the opening.
As shown in fig. 1, the side wall of the building 1 is provided with a rope control device for receiving and controlling the ropes 5. The cord 5 and the movable window 3 are configured to: when the cord 5 is tightened, the movable window 3 can move from the open position to the closed position; when the cord 5 is released, the movable window 3 can move from the closed position to the open position. In this application, the spindle (not shown) of the handle 4 can be inserted into the second end hollow 417 (see fig. 2) of the cord control device. When the user turns the handle 4, the rope control means can release or tighten the rope 5. Those skilled in the art will appreciate that the rope 5 of the present invention may be a wire rope or other various kinds of ropes.
As shown in fig. 1, the control system includes a control device 91. It may be provided in the rope control device or at any point inside the building 1 or outside the building 1.
As shown in fig. 2 to 6, the rope control device of the present invention includes a base 10, a storage wheel 40, a speed adjusting device, a limiting device, a starting device, a first cover 21, a second cover 22, and a third cover 23. Wherein, the base 10 is used for bearing the containing wheel 40, the speed regulating device, the limiting device 60 and the starting device. The first cover 21, the second cover 22, and the third cover 23 cover the base 10 to protect the components accommodated in the base 10. The storage wheel 40 is used to store the rope 5 and can control the release or tightening of the rope 5. The speed regulating device is disposed between the base 10 and the receiving wheel 40 to regulate the rotation speed of the receiving wheel 40. The stopper 60 is used to limit the storage wheel 40. The stop 60 has a first position and a second position. When the position limiting device 60 is located at the first position, the receiving wheel 40 can only rotate in the clockwise direction (i.e., the first direction). When the position limiting device 60 is located at the second position, the receiving wheel 40 can rotate in a clockwise direction (i.e., the first direction) or in a counterclockwise direction (i.e., the second direction). The activation device is used to control the movement of the stop device 60 from the first position to the second position.
The specific structure of each component in the rope control device of the present invention is described below with reference to fig. 2 to 15:
as shown in fig. 2-6, the base 10 defines a base receptacle 11. The upper part of the base receptacle 11 is substantially circular and the lower part is substantially rectangular, the upper circular part having a central axis X. The base housing 11 is used for accommodating the receiving wheel 40 and the speed adjusting device 50. A decelerating wall 111 is arranged in the base accommodating cavity 11. The decelerating wall 111 is substantially a circular ring, which is arranged coaxially with the circular volume of the upper part of the base volume 11. That is, the decelerating wall 111 also has a central axis X. The speed reduction wall 111 has a hollow portion for accommodating the speed reduction mechanism 51. The speed reduction wall 111 and the speed reduction mechanism 51 form a speed reduction device.
As shown in fig. 2 to 8, the receiving wheel 40 includes a receiving wheel body 41, a sleeve 414, and a pin 412. The storage wheel body 41 is substantially cylindrical and has a storage wheel axis. When the stowing wheel 40 is fitted in position with the base 10, the stowing wheel axis is disposed coaxially with the central axis X. The storage wheel body 41 is provided with a string accommodating portion 43 on a circumferential side wall thereof, which is formed by recessing from the circumferential side wall of the storage wheel body 41 toward the storage wheel axis. The string accommodating portion 43 accommodates the string 5. The receiving wheel body 41 is provided with a first pin hole 46 on a circumferential side wall thereof for receiving the pin 412. The left end of the circumferential side wall of the storage wheel body 41 is provided with an outer ring gear. Each tooth in the outer gear ring is a ratchet tooth 42. The ratchet teeth 42 are configured such that the left portion of the receiving wheel body 41 forms a ratchet, and the ratchet can be engaged with the stopper 63 in the stopper device 60. More specifically, each of the ratchet teeth 42 has a first tooth face 112 and a second tooth face 113. The first tooth surface 112 extends substantially in the radial direction of the receiving wheel body 41. The second tooth face 113 is arranged at an acute angle to the first tooth face 112, and the second tooth face 113 is located downstream of the first tooth face 112 in the clockwise direction. The stop 60 has a first position and a second position. When the limiting device 60 is located at the first position, the free end of the limiting member 63 contacts the ratchet teeth 42, so that the receiving wheel 40 can only rotate in the clockwise direction (i.e., the first direction) about the central axis X. When the limiting device 60 is located at the second position, the limiting member 63 does not contact the ratchet teeth 42, so that the receiving wheel 40 can rotate in the clockwise direction (i.e., the first direction) or the counterclockwise direction (i.e., the second direction) about the central axis X.
It should be noted that, in the example of the present invention, when the storage wheel 40 rotates in the clockwise direction around the central axis X, the rope 5 is tightened, and when the storage wheel 40 rotates in the counterclockwise direction around the central axis X, the rope 5 is released.
As shown in fig. 2-8, the collector wheel pocket 45 extends through the collector wheel body 41 along the collector wheel axis. A vertically arranged partition plate 47 is arranged in the containing wheel cavity 45 to divide the containing wheel cavity 45 into a left part and a right part. The left portion of the collector wheel receptacle 45 is for receiving the planetary mechanism 52. The partition plate 47 has a through hole disposed coaxially with the receiving wheel axis for receiving the boss 414. The left end of the sidewall of the receiving wheel cavity 45 is provided with an inner gear ring 44 for meshing with the first planetary gear 611 and the second planetary gear 612 of the planetary mechanism 52. The sleeve 414 is generally cylindrical and is disposed in the wheel well 45 coaxially with the wheel body 41. Both ends of the sleeve 414 have hollow portions depressed inward, respectively. Wherein the first end hollow 416 is adapted to receive the turning rod 502 and the second end hollow 417 is adapted to receive a turning shaft (not shown) of the handle 4. The sleeve 414 has a second pin hole 415 extending vertically therethrough for receiving the pin 412. After the sleeve 414 passes through the through hole in the partition plate 47, the pin 412 passes through the first pin hole 46 and the second pin hole 415 to hold the pin 412 in place. As the hub 414 rotates, the receiving wheel 40 also rotates. In other words, rotation of the handle 4 can rotate the storage wheel 40.
As shown in fig. 9, the planetary mechanism 52 is accommodated in the left portion of the receiving wheel housing 45. The planetary mechanism 52 includes a carrier 610, and two planetary gears (i.e., a first planetary gear 611 and a second planetary gear 612). The first planetary gear 611 and the second planetary gear 612 are disposed on the same side of the carrier 610, and are connected with the carrier 610. The carrier 610 is provided with a through hole 613 so that the transmission gear 503 in the speed reducing mechanism 51 can mesh with the first planetary gear 611 and the second planetary gear 612 after passing through the through hole 613 from the rear side of the carrier 610. Further, the first planetary gears 611 and the second planetary gears 612 are also meshed with the ring gear 44 in the storage wheel 40.
As shown in fig. 2 to 13, the speed adjusting device includes a speed reducing mechanism 51 accommodated in a housing (i.e., a hollow portion) surrounded by a speed reducing wall 111. The speed reducing mechanism 51 includes a rotating member 53 and a speed reducing assembly 54. The rotating member 53 includes a rotating body 501, a rotating lever 502, and a transmission gear 503. Wherein the rotating body 501 is substantially cylindrical, having an axis of rotation. The rotating body 501 is disposed coaxially with the decelerating wall 111. Four second guide receiving holes 504 are formed in a side wall of the rotating body 501 and are uniformly distributed in the circumferential direction thereof, and are configured to receive four guides 521, respectively. The rotating rod 502 is disposed coaxially with the rotating body 501. An end portion of the rotating lever 502 is received by the first end hollow portion 416 of the receiving wheel 40, and the rotating lever 502 is rotatable relative to the boss 414. A transmission gear 503 is provided on the rotation lever 502 so that the rotation of the transmission gear 503 can rotate the rotation body 501.
The deceleration assembly 54 includes four deceleration blocks 511, four guides 521, and a deceleration elastic member 531. Four deceleration blocks 511 are arranged around the rotating body 501. The specific structure of each of the four deceleration blocks 511 is the same. Preferably, the deceleration block 511 is made of metal. Specifically, the deceleration block 511 is substantially a sector cylinder. Having arcuate outer and inner side walls 514,515. The arc of the inner sidewall 515 is the same as the arc of the sidewall of the rotating body 501. The deceleration block 511 is provided with a first guide accommodating hole 513. A first guide receiving hole 513 is formed extending radially from the inner sidewall 515 to the outer sidewall 514 for receiving the guide 521. The deceleration block 511 is also provided with an elastic body housing 512. The elastic body accommodating portion 512 is formed to extend from the outer sidewall 514 to the inner sidewall 515 in the circumferential direction, and accommodates a portion of the decelerating elastic member 531. The specific structure of each of the four guides 521 is the same. Specifically, the guide 521 is substantially cylindrical, and one end thereof is received in the second guide receiving hole 504 of the rotating body 501 and the other end thereof is received in the first guide receiving hole 513, so that the four speed reduction blocks 511 and the rotating member 53 are movably coupled together. When the rotating member 53 and the reduction assembly 54 are assembled in place, the four reduction blocks 511 are able to move relative to the rotating member 53 along the four guides 521, respectively. The decelerating elastic member 531 has a ring shape. Which is provided around the four deceleration blocks 511 and is accommodated in the elastic body accommodating portion 512 on the four deceleration blocks 511.
When the speed reduction mechanism 51, the planetary mechanism 52 and the storage wheel 40 are assembled in place, the user rotates the handle 4, and the handle 4 rotates the storage wheel 40. Since the ring gear 44 in the storage wheel 40 is engaged with the first planetary gears 611 and the second planetary gears 612, and the first planetary gears 611 and the second planetary gears 612 are engaged with the transmission gears 503, when the storage wheel 40 rotates, the ring gear 44 of the storage wheel 40 rotates, thereby rotating the two planetary gears. The rotation of the two planetary gears rotates the transmission gear 503 in the reduction mechanism 51, thereby rotating the rotating body 501. When the user rotates the handle 4, the rotational speed of the storage wheel 40 is the same as the speed at which the user rotates the handle 4. The two planetary gears can accelerate the rotation of the transmission gear 503 so that the rotation speed of the transmission gear 503 is greater than the rotation speed of the storage wheel 40.
The deceleration principle of the deceleration assembly 54 is based on the rotational speed of the drive gear 503. The deceleration principle of the deceleration assembly 54 is described below with reference to fig. 12-13:
fig. 12 is a diagram showing a state where the rotating member 53 in the speed reducing mechanism 51 rotates at a low speed. As shown in fig. 12, the rotating member 53 and the four speed reduction blocks 511 are rotating at a low speed. The four deceleration blocks 511 are rotated while being subjected to centrifugal force, and are separated from the rotating member 53 along the four guides 521, respectively. The decelerating elastic member 531 is expanded by the four decelerating blocks 511 away from the rotating part 53. The deformed deceleration elastic member 531 generates a contraction force toward the rotation member 53 to the four deceleration blocks 511. At this time, the four deceleration blocks 511 are held in place by centrifugal and contraction forces in opposite directions. Since the rotational speed of the rotational member 53 is slow, the four deceleration blocks 511 have not yet contacted the deceleration wall 111. The rotating member 53 can rotate at its own rotational speed. At this time, the speed at which the user rotates the handle 4 is the actual rotational speed of the handle 4.
Fig. 13 is a state diagram in which the rotating member 53 in the speed reducing mechanism 51 rotates at a high speed. As shown in fig. 13, the rotating member 53 and the four speed reduction blocks 511 are rotating at high speed. The four deceleration blocks 511 are rotated while being subjected to centrifugal force, and are separated from the rotating member 53 along the four guides 521, respectively. The decelerating elastic member 531 is expanded by the four decelerating blocks 511 away from the rotating part 53. Since the four guides 521 rotate faster around the shaft 202, the centrifugal force applied to the four guides 521 is greater than the contraction force generated by the deceleration elastic member 531, and the four deceleration blocks 511 contact the deceleration wall 111. The four deceleration blocks 511 contacting the deceleration wall 111 receive a frictional force applied thereto by the deceleration wall 111, thereby causing the four deceleration blocks 511 to rotate slowly about the axis of the shaft 202. Since the four deceleration blocks 511 are relatively movably connected to the rotating member 53 by the four guides 521, respectively, the rotation of the four deceleration blocks 511 is slowed, so that the rotation of the rotating member 53 is also slowed. Thereby, the rotation speed of the rotating member 53 is reduced. The rotating member 53, the rotation speed of which is reduced, restricts the rotation of the storage wheel 40, so that the user feels a large rotational resistance. At this time, although the user rotates the handle 4, the user feels a rotational resistance so that the user rotates the handle 4 more slowly.
The utility model discloses a reduction gears 51 among the rope controlling means can be adapted to the rate of motion of handle 4 and make the slew velocity who accomodates wheel 40 slow down. That is, when the rotation speed of the handle 4 is slow, the reduction mechanism 51 does not reduce the speed of the storage wheel 40. When the rotation speed of the handle 4 is fast, the reduction mechanism 51 reduces the speed of the storage wheel 40, and when the rotation speed of the handle 4 is fast, the force of the four reduction blocks 511 against the reduction wall 111 is larger, the friction force generated by the reduction wall 111 is larger, and accordingly, the reduction degree of the storage wheel 40 by the reduction mechanism 51 is larger.
It should be noted that although four speed reduction blocks 511, four guiding elements 521 and four corresponding second guiding element receiving holes 504 and four second receiving holes 403 are illustrated in the present application, those skilled in the art will understand that at least two speed reduction blocks 511 and the number of guiding elements 521, second guiding element receiving holes 504 and second receiving holes 403 matching the speed reduction blocks are within the scope of the present invention.
It should also be noted that although two planetary gears are shown in the present application, one skilled in the art will appreciate that at least one planetary gear is within the scope of the present invention.
In order to prevent the abrasion of the deceleration wall 111, the inner side wall of the deceleration wall 111 may be provided with a spacer for contacting the deceleration block 511.
As shown in fig. 2-6 and 14-15, the actuating means and the limiting means 60 are housed in a rectangular housing in the lower part of the base 10. The limiting device 60 comprises a limiting seat 61, a limiting piece 63, a limiting elastic component 64, a limiting linkage rod 68 and a resetting elastic component 69. The stop 60 has a first position and a second position. Correspondingly, the limiting seat 61, the limiting piece 63 and the limiting linkage rod 68 in the limiting device 60 also have a first position and a second position. Wherein, the limiting seat 61 can be rotatably connected to the base 10 around the limiting axis Y. More specifically, the position-limiting base 61 is rotatably connected to the base 10 via the first rotating shaft 621. By rotating, the stopper seat 61 can move from the first position to the second position, or from the second position to the first position. The first end of the limiting member 63 is rotatably connected to the limiting base 61 through the second rotating shaft 622. The second end of the limiting member 63 is a free end for contacting the ratchet teeth 42, thereby limiting the rotational direction of the receiving wheel 40. The elastic limiting member 64 is used for providing a force against the ratchet teeth 42 when the limiting member 63 is located at the first position, so as to prevent the receiving wheel 40 from rotating in the counterclockwise direction. Specifically, one end of the elastic stopper 64 is connected to the stopper base 61, and the other end of the elastic stopper 64 is connected to the stopper 63. When the position-limiting device 60 is located at the first position, the position-limiting elastic member 64 generates a force to the position-limiting member 63, so as to press the second end of the position-limiting member 63 against the ratchet teeth 42. When the receiving wheel 40 rotates in the counterclockwise direction, the first tooth surface 112 contacts the second end of the limiting member 63 and is abutted by the limiting member 63 so as not to rotate in the counterclockwise direction. When the receiving wheel 40 rotates in the clockwise direction, the second tooth surface 113 contacts the second end of the limiting member 63, and the second tooth surface 113 applies a force to the limiting member 63 toward the limiting elastic member 64, so that the limiting member 63 moves toward the limiting elastic member 64, and the limiting member 63 can pass over the second tooth surface 113 of one ratchet tooth 42 and contact the second tooth surface 113 of the adjacent ratchet tooth 42. Thus, when the position limiting device 60 is located at the first position, the receiving wheel 40 can only rotate in the clockwise direction (i.e., the first direction) and cannot rotate in the counterclockwise direction. The spacing linkage 68 is arranged generally in an up-down direction. The first end (i.e., the upper end) of the spacing linkage rod 68 is connected with the spacing seat 61, so that when the spacing device 60 rotates around the first rotating shaft 621, the spacing linkage rod 68 can rotate around the first rotating shaft 621 together. One end of the elastic resetting component 69 is connected with the lower part of the limit linkage rod 68, and the other end is connected with the base 10, and is used for providing driving force for the movement of the limit device 60 from the first position to the second position. Specifically, when the position limiting device 60 is in the first position, the return elastic member 69 is in a stretched state.
As shown in fig. 14-15, the position limiting device 60 is further provided with a reset rod 67. The reset lever 67 is disposed perpendicular to the plane of the base 10. Specifically, one end of the reset rod 67 is connected to the limiting seat 61, and the other end is a free end, so that the user can conveniently dial the reset rod. The utility model discloses in, release link 67 can pass the third lid through-hole of third lid 23 to the user's operation.
As shown in fig. 4, a position sensor 93 is also provided in the base 10. Which is disposed generally to the right of the stop 60. The position sensor 93 is communicatively connected to the control device 91. The position sensor 93 has a trigger 94. When the trigger 94 contacts the position limiter 60, the position sensor 93 sends a position signal to the control device 91. Further, the position sensor 93 is also configured to: when the stop 60 is in the first position, the stop 60 is disengaged from the trigger 94; and when the stop 60 is in the second position, the stop 60 contacts the trigger 94. The control device 91 can determine the position of the stopper device 60 based on the position signal.
As shown in fig. 3-6, the activation device includes a fuse activation device, a manual activation device, and an activation linkage 81. The fuse actuator includes a fuse housing 901, a fuse element 902, a fuse spring 903, and an output rod 72. The fuse housing 901 is disposed at the lower right of the base cavity 11 and does not move relative to the base 10. A fuse element 902 and a fuse spring 903 are disposed in the fuse housing 901. The upper portion of the output rod 72 is disposed in the fuse housing 901, and the lower portion of the output rod 72 protrudes from the lower edge of the fuse housing 901 to be connected to the actuating link 81. Specifically, the output rod 72 is generally right-angled and is movable relative to the fuse housing 901 and the base 10. More specifically, the output lever 72 has an output lever initial position and an output lever predetermined position, and can be located at the output lever initial position or the output lever predetermined position by moving up and down (i.e., translational movement). One end of the fuse spring 903 is connected to the lower edge of the fuse housing 901, and the other end is connected to the upper portion of the output rod 72. Fuse spring 903 remains compressed, thereby applying an upward force to output rod 72. The fuse 902 has one end connected to an upper edge of the fuse housing 901 and the other end connected to an upper portion of the output rod 72. The fuse 902 is capable of abutting against the output rod 72, thereby holding the output rod 72 in the output rod initial position. The fuse 902 can be adapted to the ambient temperature in which it is located. Specifically, the fuse 902 is configured to: when the indoor ambient temperature is greater than a set temperature (e.g., 70 ℃), the fuse 902 melts and breaks. The broken fuse 902 no longer abuts the upper portion of the output rod 72 and the fuse spring 903 in the compressed state exerts an upward force on the output rod 72 to move the output rod 72 upward from the output rod initial position to the output rod predetermined position. As one example, the fuse 902 may be various types of metal alloys, the melting point of which is determined according to the set temperature.
It should be noted that the present invention only shows a specific arrangement of the fusing start device. Those skilled in the art can adjust the specific structure and position of the various components of the fuse actuator according to the spirit of the present invention, as long as the actuating linkage 81 is moved from the engageable position to the non-engageable position when the fuse element 902 is melted.
As shown in fig. 3 to 6, the manual actuating means includes a pressing piece 73, an actuating lever 74, and a pressing elastic member 75. Specifically, referring to fig. 5, the pressing member 73 is disposed perpendicular to the plane of the base 10. The pressing piece 73 has an inclined portion at its center and a thin free end at its right end. The actuating lever 74 is arranged generally in the up-down direction and has an actuating lever initial position and an actuating lever predetermined position. The activation lever 74 can be located at an activation lever initial position or an activation lever predetermined position by moving up and down (i.e., translational movement). The actuating lever 74 has an aperture 76 therein. The free end of the presser 73 is accommodated in the hole 76. The pressing elastic means 75 is provided between the pressing piece 73 and the actuating lever 74 such that the pressing piece 73 is away from the actuating lever 74. The inclined portion of the pressing member 73 is fitted with the hole 76 of the actuating lever 74 so that when the user presses the pressing member 73, the movement of the pressing member 73 toward the actuating lever 74 moves the actuating lever 74 upward and reaches the actuating lever predetermined position. The pressing elastic member 75 is configured to: when the user releases the pressing piece 73, the pressing elastic means 75 applies force to the pressing piece 73, so that the pressing piece 73 is moved away from the actuating lever 74, and the actuating lever 74 is moved downward to an actuating lever initial position. The actuating lever 74 is also provided with a guide hole 77. The guide hole 77 is arranged on the activation lever 74 substantially in the up-down direction. An auxiliary member 78 is connected to the base frame 10 through the guide hole 77 to assist the movement of the actuating lever 74 in the up-and-down direction. An activation linkage 81 is provided at the lower portion of the base receptacle 11 and is arranged substantially parallel to the base of the base receptacle 11. An activation linkage 81 is rotatably connected to the base 10 and has an engageable position and a non-engageable position. By turning, the activation linkage 81 can be in either an engageable or a non-engageable position. Specifically, the left end of the start linkage rod 81 is provided with a snap-in portion 812 for receiving the second end (i.e., the lower end) of the limit linkage rod 68. The actuating linkage 81 is connected to the base 10 by a connection 811 and can rotate about the connection 811. The lower end of the actuating lever 74 of the manual actuating device is rotatably connected with the right portion of the actuating linkage 81 so that when the user presses the pressing piece 73, the upward movement of the actuating lever 74 can rotate the actuating linkage 81 about the connecting piece 811 in the counterclockwise direction to move from the engageable position to the non-engaged position. The lower end of the output rod 72 of the fusing start device is rotatably connected with the right part of the start linkage rod 81, so that when the fuse 902 is fused and broken, the upward movement of the output rod 72 can drive the start linkage rod 81 to rotate around the connecting piece 811 in the counterclockwise direction. Therefore, no matter the fusing starting device or the manual starting device, the starting linkage rod 81 can be driven to rotate around the connecting piece 811 in the counterclockwise direction to move from the non-engagement position to the engagement position.
It will be appreciated by those skilled in the art that the actuating means is not limited to the inclusion of the fuse actuating means and the manual actuating means described in the present application to move the actuating linkage 81 between the non-engaging and the engageable positions. As an example, the activation device may also comprise an electrically powered device. The electrical means may be a drive member such as a motor to drive the output rod 72 from its initial position to its predetermined position, thereby causing the actuating linkage 81 to rotate in a counterclockwise direction about the connection 811 to move from its non-engaged position to its engageable position.
The following describes a specific structure and an application process of the manual-automatic integrated intelligent smoke and heat exhausting system with reference to fig. 4 and 6:
when the indoor environment of the building 1 is in a normal state (i.e., a non-fire state), the movable window 3 is located in the closed position. At this point, the activation lever 74 is in the activation lever home position, the output lever 72 is in the output lever home position, the activation linkage 81 is in the engageable position and the stop 60 is in the first position. Since the catching portion 812 of the spacing linkage bar 68 abuts against the second end (i.e., the lower end) of the activation linkage bar 81, the components can be held in place. The free end of the limiting member 63 in the limiting device 60 abuts against the ratchet teeth 42, so that the take-up wheel 40 can only rotate in the clockwise direction, and the take-up wheel 40 rotating in the clockwise direction can only take up the rope 5. In other words, the storage wheel 40 rotating clockwise can only store the rope 5 tighter. Thereby, when the indoor environment of the building 1 is a normal state, the movable window 3 can be held in the closed position. Note that, when the indoor environment of the building 1 is in a normal state (i.e., a non-ignition state), the stopper 60 is located at the first position, and therefore the stopper 60 is separated from the position sensor 93. In other words, the position restricting device 60 does not contact the position sensor 93.
When the indoor ambient temperature of the building 1 increases (i.e., a fire state), and the indoor ambient temperature is greater than a set temperature (e.g., 70 ℃), the fuse 902 melts and breaks. The fuse spring 903 in a compressed state applies an upward force to the output rod 72 to move the output rod 72 from the output rod initial position to the output rod predetermined position. Movement of the output rod 72 will cause the actuating linkage 81 to move in a counterclockwise direction about the connection 811 from the engageable position to the non-engaged position. The catch portion 812 of the activation linkage 81 no longer abuts against the second end (i.e., lower end) of the restraining linkage 68. The limiting linkage rod 68 drives the limiting device 60 to move from the first position to the second position in the counterclockwise direction around the first rotating shaft 621 under the action of the resetting elastic component 69. The free end of the stop member 63 no longer abuts the ratchet teeth 42 to allow the receiving wheel 40 to rotate in the counterclockwise direction. The user rotates the handle 4 in a counterclockwise direction to rotate the take-up wheel 40 to release the cord 5. The cord 5 no longer restricts the movable window 3 and the movable window 3 moves from the closed position to the open position. Thereby, the movable window 3 is opened, and the smoke in the room can be exhausted out of the building 1. It should be noted that when the stop 60 moves from the first position to the second position, the stop 60 contacts the trigger 94. The position sensor 93 sends a position signal to the control device 91.
The utility model discloses an among the manual-automatic intelligence heat extraction system that discharges fume, the user also can press down the pressing piece 73 when indoor ambient temperature risees (promptly, the state of catching fire) and make and open movable window 3. Specifically, the user presses the pressing piece 73, and the inclined portion of the pressing piece 73 applies a force to the activation lever 74 to move the activation lever 74 from the activation lever initial position to the activation lever predetermined position. The activation lever 74 moves the activation linkage 81 in a counterclockwise direction about the connection 811 from the engageable position to the non-engaged position. The catch portion 812 of the activation linkage 81 no longer abuts against the second end (i.e., lower end) of the restraining linkage 68. The limiting linkage rod 68 drives the limiting device 60 to move around the first rotating shaft 621 along the counterclockwise direction from the first position to the second position under the action of the resetting elastic component 69. The free end of the stop member 63 no longer abuts the ratchet teeth 42 to allow the receiving wheel 40 to rotate in the counterclockwise direction. The user rotates the handle 4 in a counterclockwise direction to rotate the take-up wheel 40 to release the cord 5. The cord 5 no longer restricts the movable window 3 and the movable window 3 moves from the closed position to the open position. Thereby, the movable window 3 is opened, and the smoke in the room can be exhausted out of the building 1.
The utility model discloses a manual-automatic intelligence heat extraction system mechanism of discharging fume is compact, easy operation and the reliability is high. The rope control device is matched with the containing wheel 40, the limiting device 60, the starting linkage rod 81 and the fusing starting device, so that the fusing starting device can control the limiting device 60 based on the environmental temperature, and the containing wheel 40 is limited. Further, since the cord control device requires the user to shake the handle 4, the cord control device will be installed at a position where the user's hand can operate (e.g., 1.5m off the ground). Since the fuse starting device is installed in the rope control device, the fuse starting device is also installed at a lower position, which is equal to the user's activity height. Which can respond more quickly to changing indoor temperatures. The fuse activation device is able to move the stop means 60 from the first position to the second position to enable the user to rotate the handle 4 even if the user is unaware of the need to evacuate the smoke.
It will be appreciated by those skilled in the art that the cord control device may also be provided with an audio device (e.g., a speaker, etc.) and a display device (e.g., a light, a display screen, etc.) in communication with the control device to audibly or visually alert the user whether the stowing wheel 40 is currently able to rotate in the first direction or the second direction.
The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which may be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
