Embodiment 1

[0023] Such as figure 1 — Figure 4 As shown, a failure-proof pneumatic window opener includes a cylinder body 7, an upper end cover 10 is provided on the top of the cylinder body 7, and a lower end cover 5 is provided at the bottom, and the lower end cover 5 is fixed on the cylinder by a first clamp spring 6. At the bottom of the body 7, an air chamber 8 with a hollow structure is provided inside the cylinder body 7, and the air chamber 8 is cylindrical; the gas spring 1, the gas spring 1 has a sleeve 2, and the bottom of the sleeve 2 A piston 19 that can axially reciprocate in the air chamber 8 is installed, and the piston 19 is fixed on the bottom of the gas spring 1 through the second clip 17. A support rod 4 is installed in the sleeve 2, and the support rod 4. One end is connected to the lower end cover 5, and the other end is located in the sleeve 2. When the gas spring 1 is opened, the support rod 4 pushes the sleeve 2 out of the cylinder body 1. When the gas spring 1 ...

Embodiment 2

[0030] Select an office building in Zhengzhou as the experimental object, with an area of ​​150 square meters. Experiment time: April 9, 2018, the indoor temperature was 18°C, and the outdoor temperature was 21°C.

[0031]Because the lighting is better near the window, there are usually office desks, chairs or filing cabinets near the window. Therefore, wooden tables and chairs, waste paper and rags are used to simulate the office space.

[0032] Adjust the air source pressure of the window opener to 0.2 MPa, set the burst temperature of the temperature-sensitive glass bulb 14 in the pressure relief device 12 to 68 degrees, ignite combustibles such as wooden tables and chairs, waste paper and rags, and stand at the ignition point 5 Meters away, measure the temperature of the cylinder block 7 of the window opener in real time with a temperature measuring gun. After the fire source is turned off, the air source of the window opener is manually turned off, and the timing is set...

Embodiment 3

[0035] Select an office building in Zhengzhou as the experimental object, with an area of ​​150 square meters. Experiment time: April 10, 2018, the indoor temperature was 19°C, and the outdoor temperature was 21°C.

[0036] Because the lighting is better near the window, there are usually office desks, chairs or filing cabinets near the window. Therefore, wooden tables and chairs, waste paper and rags are used to simulate the office space.

[0037] The air source pressure of the window opener is adjusted to 0.25MPa, and the bursting temperature of the temperature-sensitive glass bubble 14 in the pressure relief device 12 is set to 68 degrees. Meters away, measure the temperature of the cylinder block 7 of the window opener in real time with a temperature measuring gun. After the fire source is turned off, the air source of the window opener is manually turned off, and the timing is set. At this time, the window opener will automatically open. When the window opener is fully ...

Abstract

The invention discloses an anti-failure pneumatic window opener. The window opener comprises a cylinder body, an air spring, a pressure relief device, an air inflation channel and a limiting block, wherein an upper end cover is arranged at the top of the cylinder body, a lower end cover is arranged at the bottom of the cylinder body, the air spring is provided with a sleeve, a piston capable of axially reciprocating in an air chamber is arranged at the bottom of the sleeve, a supporting rod is arranged in the sleeve, when the air spring is opened, the supporting rod ejects the sleeve out of the cylinder body, when the air spring is completely closed, the supporting rod is integrally stored in the sleeve, the pressure relief device is located on one side of the upper end of the cylinder body, the position between the air chamber and the outer wall of the cylinder body is provided with the air inflation channel, one end of the limiting block is connected to the bottom of the upper end cover, and the other end of the limiting block extends towards the interior of the air chamber. According to the window opener, during the normal operation, namely, when an air source is in an on state,the window opener is in a completely closed state; when an air source is in an off state, the window opener can be automatically opened, the problem that when a fire occurs, the air source is in an off state, and the window opener cannot be opened can be solved, and better economic benefits can be generated.

Description

technical field [0001] The invention relates to the technical field of window drives, in particular to an anti-failure pneumatic window drive. Background technique [0002] With the development of the economy and the continuous advancement of national urbanization, there are more and more office buildings, villa communities, large stadiums and public event venues. In order to obtain better lighting effects, these buildings are often installed with larger windows. These windows or installation position are too high, or weight is too heavy, cause certain difficulty to people when opening, closing window. In order to solve this problem, technicians have successively developed window openers with electric or pneumatic power sources. Among them, pneumatic window openers are powered by compressed air, consume very little power, are energy-saving and environmentally friendly, and are used by more and more people. favored by consumers. [0003] However, there are still some proble...
