Description

Technical Field

[0001] The utility model belongs to the technical field of shutters, and in particular relates to an automatic fire-fighting smoke exhaust shutter. Background Art

[0002] Building fire protection facilities are important facilities to ensure building fire safety and personnel evacuation safety. In order to reasonably design building smoke prevention and exhaust systems, ensure construction quality, standardize acceptance and maintenance management, reduce fire hazards, and protect personal and property safety, the Ministry of Housing and Urban-Rural Development has issued GB51251-2017 "Technical Standards for Building Smoke Prevention and Exhaust Systems", which puts forward standard requirements for building smoke exhaust systems. The standard puts forward clear requirements for the setting of natural smoke exhaust windows in factories and warehouses. When set on the roof, the natural smoke exhaust windows should be evenly set on the roof and should be opened by automatic control; when the roof slope is less than or equal to 12°, a corresponding natural smoke exhaust window should be set for every 200m2 of building area; when the roof slope is greater than or equal to 12°, a corresponding natural smoke exhaust window should be set for every 400m2 of building area.

[0003] For factories, warehouses and other buildings that do not meet the requirements, corresponding renovations must be carried out. However, the height of the general roof smoke exhaust windows is relatively high, which affects the aesthetics of the building. Shutters are generally thinner and simpler in structure, which are easy to construct and install, and can meet the renovation and aesthetic requirements. However, the main function of existing shutters is to let in air, and the smoke exhaust effect is extremely poor. They cannot automatically switch the opening and closing action, and cannot automatically adapt to environmental parameters to open and close accordingly. (For high-rise buildings in extremely cold areas, the temperature difference between indoors and outdoors is large, and the indoor warm air is drawn to the outdoors in large quantities through the smoke exhaust duct, causing the indoor temperature to drop), so there is an urgent need for an automatic fire smoke exhaust shutter. Utility Model Content

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides an automatic fire smoke exhaust shutter to solve the problems in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An automatic fire smoke exhaust shutter, comprising a window body, a plurality of shutters pivotally connected to the window body, and further comprising;

[0007] A drive assembly connected to the shutter, the drive assembly comprising a drive element;

[0008] The monitoring unit includes a temperature sensor, a smoke sensor and a control unit. The temperature sensor and the smoke sensor are electrically connected to the control unit, and the control unit is electrically connected to the driving element.

[0009] Furthermore, the window body is provided with at least one installation window, and the shutter is pivotally connected to the frame bar of the installation window.

[0010] Furthermore, the shutter comprises a shutter body, and pivot parts protrude outwards at left and right ends of the shutter body, the pivot parts are parallel to the central axis of the shutter body, and the pivot parts are pivotally connected to the frame bar.

[0011] Furthermore, buckle plates are connected to the upper and lower sides of the shutter body, and the buckle plates on adjacent shutters can be buckled with each other.

[0012] Furthermore, the driving assembly also includes a connecting plate and a driving plate, one end of the connecting plate is fixedly connected to the pivot portion, and the other end is hinged to the driving plate, the output end of the driving element is connected to a connecting head, and a connecting rod is fixedly connected between the connecting head and the driving plate.

[0013] Furthermore, the monitoring unit also includes a substrate, a humidity sensor and an alarm, and the control unit, the temperature sensor, the humidity sensor, the smoke sensor and the alarm are all mounted on the substrate.

[0014] Furthermore, the driving element is a telescopic motor or a cylinder.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. The shutters are equipped with temperature sensors, humidity sensors and smoke sensors. When smoke appears, the alarm can be triggered and the control unit can be used to control the driving element to open or close the shutters. The extension and retraction of the driving element drives the driving plate to move horizontally through the connecting head and the connecting rod.
