Description

Technical Field

[0001] The utility model relates to the technical field of smoke exhaust devices located at the ceiling, and particularly relates to a hoisting type smoke exhaust structure with adjustable wind speed. Background Art

[0002] In the current fields of building design and fire safety, the ceiling smoke exhaust system plays a crucial role. At present, the ceiling smoke exhaust system is widely used in various buildings, including commercial complexes, office buildings, hotels, hospitals, and residences. The existing ceiling smoke exhaust systems usually adopt mechanical smoke exhaust or natural smoke exhaust methods. Natural smoke exhaust utilizes openings such as windows and balconies of the building to discharge smoke. This method has the advantages of energy conservation and environmental protection, but is greatly affected by the building structure and external environment, and the smoke exhaust effect may not be stable enough. In terms of mechanical smoke exhaust, the smoke exhaust air volume and wind speed can usually be automatically adjusted according to the fire situation to improve the smoke exhaust effect, but there are problems such as high equipment maintenance costs and large operating energy consumption. The invention patent with the application number 202211003982.0 discloses an adjustable connection structure between a wind valve and an air duct, which includes an air duct, a wind valve, a bracket, an adjusting member, a positioning member, a remote actuator, and a connecting pipe. A smoke exhaust port is opened on the air duct; the wind valve is arranged corresponding to the smoke exhaust port; the bracket is arranged on the wind valve; the adjusting member is slidably arranged in the air duct; the top end of the positioning member is connected to the adjusting member, and the bottom end is connected to the bracket; the remote actuator is arranged on the wall; one end of the connecting pipe is connected to the wind valve, and the other end is connected to the remote actuator. By arranging the adjusting member in the smoke exhaust port and pre-installing the wind valve before the ceiling layout and installation are completed, the position of the adjusting member is adjustable. Therefore, when the ceiling layout is installed to the position of the smoke exhaust port, the position of the wind valve can be adjusted. Taking the ceiling layout as a comparison, it can be accurately adjusted to its preset position. However, the setting of the connecting pipe in this structure affects the layout of the ceiling structure, and an additional hanging bracket is required for installation, which increases the difficulty of on-site construction.

[0015] AsFigure 1 A hoisting type smoke exhaust structure with adjustable wind speed as shown in the figure, including a hoisting bracket 1 fixedly installed at the bottom of the floor slab by expansion bolts. The hoisting bracket 1 includes a hanging member 10 whose top is fixedly connected to the floor slab by expansion bolts and a suspension rod 11 adjustably and fixedly installed at the bottom of the hanging member 10. The bottom of the suspension rod 11 is detachably installed on the cantilever bearing frame 4. In this embodiment, the suspension rod 11 is selected as a screw rod or a round rod with external threads at both ends, and is adjustably and fixedly connected by nuts. A shock pad 12 is arranged between the suspension rod 11 and the hanging member 10. The shock pad 12 is selected as a metal shock pad. After installation, it does not affect the installation strength of the overall structure and improves the shock absorption capacity for the installation of the smoke exhaust duct 2.

[0016] The smoke exhaust duct 2 is detachably installed on the hoisting bracket 1. Specifically, the detachable installation of the smoke exhaust duct 2 can be achieved by using fasteners, or by relying on the self - gravity of the smoke exhaust duct 2, or by using L - shaped angle codes to squeeze and fix both sides of the smoke exhaust duct 2.

[0017] A number of smoke exhaust parts 3 are hermetically arranged at intervals at the bottom of the smoke exhaust duct 2. The smoke exhaust part 3 is in the shape of a hollow cube. A cantilever bearing frame 4 is fixedly arranged on the outer wall of the smoke exhaust part 3 through fasteners. Both ends of the smoke exhaust duct 2 are located above the cantilever bearing frame 4. A connecting piece 20 is arranged outside the smoke exhaust part 3. One end of the ceiling structure 21 is installed on the connecting piece 20, which is convenient for the construction of the ceiling structure 21. The exposed parts of the hoisting bracket 1, the cantilever bearing frame 4, the smoke exhaust duct 2 and the control sleeve 6 are all located inside the ceiling structure 21.

[0018] An air valve 5 is fixedly arranged inside the smoke exhaust part 3. The air valve 5 is a mature product purchased on the market and will not be described in detail in this specification.

One end of the control sleeve 6 is hermetically installed on the side wall of the smoke exhaust air duct 2, and the other end of the control sleeve 6 is connected to a controller 7. The control cable of the controller 7 passes through the control sleeve 6 and the smoke exhaust air duct 2 and is electrically connected to the air valve 5. The operator can control the opening amount of the air valve 5 through the controller 7 to control the smoke exhaust speed. In a specific embodiment, a steel wire tube rope 8 is arranged inside the control sleeve 6, and one end of the steel wire tube rope 8 passes through the smoke exhaust air duct 2 and is located in the inner cavity of the smoke exhaust part 3. A corrugated pipe flange 9 is fixedly arranged at one end of the control sleeve 6, and the corrugated pipe flange 9 is fixedly installed on the side wall of the smoke exhaust air duct 2 through fasteners. Before the installation operation, a through hole adapted to the control sleeve 6 needs to be opened on the side wall of the smoke exhaust air duct 2, and the steel wire tube rope 8 passes through the through hole. A sealing gasket is arranged between the corrugated pipe flange 9 and the smoke exhaust air duct 2, and the sealing gasket improves the sealing performance at the connection between the corrugated pipe flange 9 and the smoke exhaust air duct 2 to prevent smoke leakage. The control sleeve 6 is made of stainless steel pipe, and the controller 7 is installed on the side wall of the wall, 1.5 m above the ground.
