Technical Field
[0001] The utility model relates to the technical field of pressure relief windows, in particular to a mine ventilation damper pressure relief window. Background Art
[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. A damper is installed at the end of the mine ventilation opening. There is an air pressure difference between the inside and outside of the mine. In order to facilitate the opening and closing of the damper, a pressure relief window needs to be installed on the damper.
[0003] When the existing mine ventilation damper pressure relief window is in use, although the window sash can automatically open under a certain pressure and release pressure outward, the existing damper pressure relief window can only relieve pressure in one direction. When the air pressure inside the mine is lower than the air pressure outside, it is also inconvenient to open and close the damper. The existing damper pressure relief window cannot achieve two-way pressure relief and is inconvenient to use. Therefore, we propose a mine ventilation damper pressure relief window to solve the problem raised. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Example:
[0020] See also Figures 1 to 3 The utility model provides a technical solution: a mine ventilation damper pressure relief window, comprising a window frame 1, a partition 2 is fixedly connected to the middle of the inner side of the window frame 1, and a first vent 3 and a second vent 4 are symmetrically penetrated on both sides of the partition 2, wherein,
[0021] A first glass window 5 is rotatably connected to the inner wall of one side of the window frame 1 corresponding to the first vent 3, and a second glass window 6 is rotatably connected to the inner wall of the other side of the window frame 1 corresponding to the second vent 4. Guide grooves 7 are symmetrically penetrated on the upper and lower sides of the partition plate 2 corresponding to the first glass window 5 and the second glass window 6;
[0022] A guide rod 8 is fixedly connected to one side of the first glass window 5 and the second glass window 6 corresponding to the guide groove 7, a baffle 9 is fixedly connected to the end of the guide rod 8 away from the baffle 9, and a spring 10 is sleeved on the guide rod 8 between the baffle 9 and the partition 2;
[0023] The first glass window 5 and the second glass window 6 are respectively arranged on both sides of the partition 2. When the air pressure inside the mine is greater than the air pressure outside, the air pressure inside pushes the second glass window 6 to overcome the elastic force of the spring 10 to rotate, open the second vent 4, and automatically complete the pressure relief of the damper. When the air pressure inside the mine is less than the air pressure outside, the air pressure outside pushes the first glass window 5 to overcome the elastic force of the spring 10 to rotate, and open the first vent 3. Through the damper pressure relief window, two-way automatic pressure relief can be achieved to open or close the damper.
[0024] See also Figures 1 to 3 The first glass window 5 and the second glass window 6 are both rectangular, and the sizes of the first glass window 5 and the second glass window 6 are larger than the opening sizes of the first vent 3 and the second vent 4. The guide rod 8 is a cylinder, and the outer diameter of the guide rod 8 coincides with the inner diameter of the guide groove 7. When the first glass window 5 and the second glass window 6 are opened and closed by rotation, the first glass window 5 and the second glass window 6 drive the guide rod 8 to move in the guide groove 7. The rotation of the first glass window 5 and the second glass window 6 is guided by the guide rod 8 and the guide groove 7 to avoid deviation of the rotation of the first glass window 5 and the second glass window 6, so that the first glass window 5 and the second glass window 6 can rotate stably.
[0025] See also Figures 1 to 3 The guide rod 8 is an arc-shaped rod, and the arc center of the guide rod 8 coincides with the rotation axis of the first glass window 5 and the second glass window 6. The baffle 9 is elastically connected to the partition 2 through the spring 10. When the first glass window 5 and the second glass window 6 are opened, the guide rod 8 is driven to move, and the guide rod 8 drives the baffle 9 to move toward the partition 2, so that the spring 10 is compressed to generate elastic force. After the pressure relief is completed, the first glass window 5 and the second glass window 6 can be automatically reset through the spring 10.
[0026] Working principle: This mine ventilation damper pressure relief window, the first glass window 5 and the second glass window 6 are respectively arranged on both sides of the partition 2. When the air pressure inside the mine is greater than the air pressure outside, the air pressure inside pushes the second glass window 6 to overcome the elastic force of the spring 10 to rotate, and the second vent 4 is opened, and the damper pressure relief is automatically completed. When the air pressure inside the mine is less than the air pressure outside, the air pressure outside pushes the first glass window 5 to overcome the elastic force of the spring 10 to rotate, and the first vent 3 is opened. Through the damper pressure relief window, two-way automatic pressure relief can be achieved, so that the damper can be opened or closed, and the first glass window 5 and the second glass window 6 can be rotated. When opening and closing, the first glass window 5 and the second glass window 6 drive the guide rod 8 to move in the guide groove 7, and the rotation of the first glass window 5 and the second glass window 6 is guided by the guide rod 8 and the guide groove 7 to avoid deviation of the rotation of the first glass window 5 and the second glass window 6, so that the first glass window 5 and the second glass window 6 can rotate stably, and when the first glass window 5 and the second glass window 6 are opened, the guide rod 8 is driven to move, and the guide rod 8 drives the baffle 9 to move toward the direction of the partition 2, so that the spring 10 is compressed to generate elastic force. After the pressure relief is completed, the first glass window 5 and the second glass window 6 can be automatically reset through the spring 10.
