[0021] 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.

[0022] The utility model aims to provide a large-section assembled mine anti-shock wave regulating wind window to solve the problems existing in the prior art. The utility model can automatically open to release the shock wave and automatically reset after the shock wave.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model provides a large-section assembled mine-use anti-shock wave regulating wind window, such as Figures 1 to 4 As shown, in this embodiment, at least one wind window module 1 is included, and the wind window modules 1 are fixedly connected by a connecting member 2; the wind window module 1 includes a frame 11, a baffle 12 and a baffle support 13. An air outlet is provided on the frame 11, and the upper edge of the baffle 12 is rotatably connected to the frame 11 above the air outlet through a hinge. In the normal state, the baffle 12 is attached to the frame 11 under the action of gravity, and the size of the baffle 12 is larger than the size of the air outlet. The baffle 12 can block the air outlet, and the baffle support 13 is fixedly connected to the frame 11 above the baffle. The baffle support 13 is set at an angle to the baffle 12. When the blast shock wave reaches the wind window, the shock wave opens the baffle 12 to play a role in pressure relief protection. The baffle 12 opens to the maximum position abutting against the baffle support 13. After the shock wave, the baffle 12 droops again and returns to its original state.

[0025] The utility model provides a large-section assembled mining anti-shock wave regulating wind window. When underground blasting is carried out, the shock wave can rush out from the air outlet and push open the baffle 12. After the shock wave, the baffle 12 automatically resets under the action of gravity and re-blocks the air outlet. The wind window modules 1 provided by the utility model have the same size, which is convenient for unified processing and manufacturing. Suitable wind windows can be assembled according to the cross-sectional size of the underground tunnel. At the same time, according to the demand for installing large wind windows in large-section underground tunnels, multiple wind window modules 1 can be provided, and they can be assembled on site after being transported to a designated location. The wind window module 1 is small in size, which is convenient for underground transportation and assembly. Several small wind window modules 1 are spliced ​​in sequence to form a large wind window. The purpose of controlling the air volume in a specific area can be achieved by controlling the opening of the wind window module 1.

[0026] In one embodiment, the connecting member 2 is a steel plate. Among the multiple wind window modules 1 that constitute the large wind window, the connecting member 2 used to connect the wind window modules 1 located at the outer edge, that is, a row of wind window modules 1 located at the top, bottom, leftmost and rightmost is convex. By passing the screws through the steel plate and tightening them on the frame 11, any two adjacent frames 11 can be connected. Among the multiple wind window modules 1 that constitute the large wind window, the connecting member 2 used to connect the wind window modules 1 located inside, that is, distributed in a field shape, is cross-shaped. By passing the screws through the steel plate and tightening them on the frame 11, four frames 11 distributed in a field shape can be connected.

[0027] In one embodiment, the baffle 12 and the baffle support 13 are vertically arranged, and the baffle support 13 is used to limit the maximum opening angle of the baffle 12 so that the baffle 12 can move within a range of 90°.

[0028] Among the optional solutions provided by the utility model, the more preferred large-section assembled mining anti-shock wave regulating wind window also includes a locking structure 14 that can fix the baffle 12 on the baffle support 13, and the locking structure 14 can keep the air outlet in an open state at all times.

[0029] In one of the embodiments, the locking structure 14 includes a bolt and a nut. The end of the bolt without a nut can pass through the baffle 12 and the baffle support 13 in sequence and be threadedly connected with the nut to fix the baffle 12 on the baffle support 13. If it is necessary to increase the air volume and open some windows, the baffle 12 can be manually opened to a position perpendicular to the frame 11, and the baffle 12 and the baffle support 13 can be fixed by the locking structure 14, so as to increase the wind cross-section.

[0030] Among the optional solutions provided by the utility model, the more preferred large-section assembled mining shock wave regulating wind window also includes a side door 3 for people to pass through. The door frame of the side door 3 can be fixed to the steel plate by screws to further achieve a fixed connection with the frame 11.

[0031] A stable and reliable ventilation system is an important basis for ensuring the safety of underground mines. It is an important part of the mine ventilation system to ensure the stability and reliability of the mine's ventilation facilities. The utility model is designed for underground mines with frequent blasting operations. The anti-shock wave wind window can effectively achieve this function. At the same time, the assembly processing and installation method is convenient for large-scale production, transportation and installation in underground tunnels, and has the characteristics of simple structure, stability and reliability.

[0032] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
