Among this technical scheme, can make apron 1 be in the second position (also the apron open mode) and can give 1 initial pushing down force of apron and realize closing (also being the first position) of the mouth of fleing under the dead weight effect of apron 1 through actuating the subassembly steadily and reliably, can be automatic smoothly to apron 1 open, guarantee that the personnel smoothly advances from the mouth of fleing under emergency state, this flap device of fleing makes full use of the dead weight of apron realizes the shutoff of the mouth of fleing, moreover, the steam generator is simple in structure.

In some embodiments, the actuating assembly includes a screw 31, a reciprocating seat 32 in threaded connection with the screw 31, and a driving member (e.g., a driving motor 36) capable of driving the screw 31 to rotate, the reciprocating seat 32 is hinged to a first end of a supporting arm 33, a second end of the supporting arm 33 is hinged to a first end of a rocker 34, the cover 1 is hinged to the cover frame 2 through a first rotating shaft 11, a second end of the rocker 34 is rotatably sleeved on the first rotating shaft 11, the reciprocating seat 32 is capable of performing a reciprocating linear motion under the action of the thread of the rotating screw 31, and when the cover 1 is in the second position, the rocker 34 is at least partially in supporting contact with the cover 1 toward a first side of the cover 1. In the technical scheme, the reciprocating seat 32, the supporting arm 33 and the rocker 34 are used as a linkage connecting rod mechanism, when the reciprocating seat 32 moves towards the first direction, the reciprocating seat can drive the rocker 34 to move close to the cover plate 1, the rocker 34 and the supporting arm 33 are folded at the hinged point, the folded rocker 34 is pushed to the inner side of the cover plate 1 and finally attached to the inner side of the cover plate 1, the position of the supporting arm 33 is not changed, the supporting arm 33 is supported at the second position kept between the cover plate 1 and the cover plate frame 2, and the reciprocating seat 32 driven by threads effectively prevents the cover plate 1 from being closed towards one side of an escape opening under the action of external force due to the action of a thread self-locking angle, so that accidents are prevented. It should be noted that in this embodiment, the first rotating shaft 11 is rotatably connected to the rocker 34, that is, the opening of the cover 1 is controlled only by the supporting function of the supporting arm 33, not the torque of the first rotating shaft 11. Due to the design, the cover plate 1 can be opened manually, and particularly, the actuating assembly is rotatably connected with the first rotating shaft 11 of the cover plate 1 through the rocker 34, so that when the driving part of the actuating assembly fails (for example, the driving motor 36 cannot be started for a long time without power shortage and the like) no matter the actuating assembly is in the first position (i.e., in the state that the escape opening is blocked, i.e., when the supporting arm 33 does not play a supporting role), the operator is not prevented from opening or blocking the escape opening manually, and the availability of the escape opening is ensured.

In order to ensure the smooth linear motion of the reciprocating base 32, the actuating assembly further comprises a linear guide 35, and the reciprocating base 32 is further connected with the linear guide 35 in a sliding manner.

As shown in fig. 2, the position of the first side surface in supporting contact with the cover plate 1 has a limiting structure, as a specific implementation manner, the limiting structure includes a limiting groove 341 configured on the first side surface and a limiting protrusion 12 configured on one side of the cover plate 1 facing the rocker 34, when the cover plate 1 is in the second position, the limiting protrusion 12 is located in the limiting groove 341, and a reliable and stable support of the support arm 33 can be ensured through the limiting structure.

In some embodiments, the first end of the rocker 34 has a hook 342, the side of the cover plate 1 facing the rocker 34 also has a hanging ring 13, the hanging ring 13 is rotatably connected with the cover plate 1, so that the hanging ring 13 can be always in a vertical state under the action of its own weight in the position switching process of the cover plate 1, for this reason, when the cover plate 1 is in the second position (specifically, opened by 90 °), the hook 342 can be buckled in the hanging ring 13, and when the cover plate 1 is in the second position to the first position, the hanging ring 13 can be far away from the hook 342 to enable the hook 342 to be disengaged from the hanging ring 13. In the technical scheme, when the cover plate 1 is at the second position, the hook 342 can be hooked in the hanging ring 13, when the cover plate 1 needs to be closed, the actuating component can be controlled to operate to enable the reciprocating seat 32 to move away from one side of the cover plate 1 (namely the first rotating shaft 11), the hook 342 of the rocker 34 applies force to the cover plate 1 through the hanging ring 13, so that the cover plate 1 deflects from the second position to one side of the first position under the action of self-weight, the reciprocating seat 32 synchronously moves away from the first rotating shaft 11, because the self-weight of the hanging ring 13 always keeps a vertical state, the hook 342 is far away from the hook 342, and the hook 342 finally separates from the hanging ring 13, in the process, the actuating component only applies force to the cover plate 1 at the starting position of the second position and realizes self-weight sealing of the escape opening after the cover plate 1 deflects for a certain angle (deviating from the 90-degree position), the structural design is novel, and the actuating component has little actuating work, reduce the energy consumption of the driving part.

The hook 342 may be detachably assembled to the first end of the rocker 34, and preferably, the hook 342 is integrally formed with the rocker 34, so that the assembly process can be simplified, and the occurrence of failure can be reduced.

In some embodiments, the torsion spring 4 is sleeved on the first rotating shaft 11, and the torsion spring 4 can simultaneously apply a force between the cover plate 1 and the cover plate frame 2 so that the cover plate 1 has an opening tendency relative to the cover plate frame 2 in the first position and has a closing tendency relative to the cover plate frame 2 in the second position. Specifically, two application of force ends of torsional spring 4 butt respectively on apron 1 and apron frame 2, when apron 1 is in the first position, thereby it is acted on by the effect of compression and counteracts on two contact members and has the trend of opening, when apron 1 is in the second position, thereby it receives the effect of tensile force and counteracts on two contact members and has the trend of closing, and because the supporting role of support arm 33 makes apron 1 keep in the second position (for example perpendicular) under this state, and can not fall or overturn to the opposite side. Understandably, due to the design of the torsion spring 4, the dead weight of the cover plate 1 can be offset to the greatest extent, so that the force required to be applied by manually opening the cover plate 1 can be effectively reduced, and the manual opening difficulty of the cover plate 1 is effectively reduced.

In some embodiments, the side of the cover plate 1 facing the escape opening is further provided with a manual locking device 5, so that the cover plate 1 is locked from the inner side of the pipe gallery and prevented from being opened in an unnecessary state. The manual locking device 5 specifically comprises a rotating handwheel 51 arranged on the cover plate 1 and a fixed latch 52 arranged on the cover plate frame 2 corresponding to the rotating handwheel 51, wherein the rotating handwheel 51 is provided with a rotating bolt matched with the fixed latch 52, and the rotating bolt can be buckled with the fixed latch 52 to form a locking when the rotating handwheel 51 is rotated along one rotation direction or can be unbuckled with the fixed latch 52 to form an unlocking when the rotating bolt is rotated along the other rotation direction.

The cover plate frame 2 is formed by assembling a plurality of hollow beam bodies, and the actuating assembly is arranged in the hollow beam bodies, so that the moving part is arranged in an independent relatively closed space, the possible injury caused by mistaken touch of an operator is prevented, and the structure of the device is more compact. The side wall of at least one side of the hollow beam body facing the escape opening is provided with a detachable maintenance cover plate 21, the maintenance cover plate 21 can cover the maintenance window, and the actuation component in the maintenance window can be maintained through the maintenance window.

The working process of the upturning type comprehensive pipe gallery escape flap device of the utility model is further explained by combining the attached figure 1.

When the escape opening needs to be electrically opened, the rotating wheel mechanism (also referred to as the manual locking device 5) of the cover plate 1 is rotated by manpower, the door seat bolt (also referred to as the fixed lock catch 52) on the escape opening seat (also referred to as the cover plate frame 2) is rotated and opened, the re-starting motor (also referred to as the driving motor 36) operates to drive the screw rod 31 to rotate, the screw rod 31 pulls the push-pull slider seat (also referred to as the reciprocating seat 32), the slider seat drives the rocker arm (also referred to as the rocker 34) to be folded upwards and lifted to drive the hinge mechanism (also referred to as the first rotating shaft 11) to rotate to open the cover plate 1 until the cover plate 1 and the escape opening are in a right angle, and the escape opening is completely opened.

When the escape opening needs to be electrically closed, the motor operates to drive the screw rod 31 to rotate in the opposite direction, the screw rod 31 pushes the sliding block seat to push, the sliding block seat drives the rocker arm to fold the hinge mechanism downwards to rotate the reverse closed cover plate 1 until the cover plate 1 and the escape opening are completely closed, at the moment, the rotating wheel mechanism of the cover plate is rotated manually, the door seat lock tongue on the escape opening seat is rotated and closed, and the escape opening is completely closed.

When the motor fails, manual replacement of electric opening and closing of the motor becomes an alternative, and although the cover plate 1 is high in mass, the cover plate can be turned up or down to be opened and closed only by small manpower due to the arrangement of the torsion spring.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
