[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] Please refer to the following Figures 1 to 4 The following describes a mine ventilation device according to an embodiment of the present invention.

[0022] like Figures 1 to 4 As shown, the mining ventilation device according to the embodiment of the present utility model includes: an air duct 1 and an exhaust assembly 2. The air duct 1 includes a cylinder 11, a baffle 12 and a locking member 13. The baffle 12 is mounted on the side wall of the cylinder 11 and defines a mounting cavity 14 together with the cylinder 11. An air inlet 111 and an air outlet 112 are respectively provided at both ends of the cylinder 11 in the axial direction. The mounting cavity 14 is in communication with the air inlet 111 and the air outlet 112. In the circumferential direction of the cylinder 11, one side of the baffle 12 is pivotally connected to the cylinder 11, and the other side of the baffle 12 is connected to the cylinder 11 by a locking member 13. The locking member 13 can lock and release the baffle 12. The exhaust assembly 2 is arranged in the mounting cavity 14. The exhaust assembly 2 includes a motor 21 and an exhaust fan 22. The exhaust fan 22 is connected to the output shaft of the motor 21 and is arranged toward the air outlet 112. The motor 21 is fixedly connected to the baffle 12.

[0023] According to the mining ventilation device of the embodiment of the present invention, since the other side of the baffle 12 is connected to the cylinder 11 via the locking member 13, the locking member 13 can lock and release the baffle 12, and the motor 21 is fixedly connected to the baffle 12. Therefore, when the exhaust assembly 2 needs to be inspected and repaired, the baffle 12 can be released by the locking member 13. At this time, one side of the baffle 12 can rotate relative to the cylinder 11, thereby removing the motor 21 and the exhaust fan 22 from the installation cavity 14 and exposing them to the outside world, thereby facilitating the operator's disassembly and inspection of the motor 21 and the exhaust fan 22.

[0024] After disassembly and maintenance are completed, the baffle 12 can be rotated and reset, and locked by the locking member 13, so that the exhaust assembly 2 can be moved back to the installation cavity 14. Therefore, the mining ventilation device of the embodiment of the utility model has a reasonable structural design, is easy to disassemble and maintain, and has a good use effect.

[0025] It is understood that when the baffle 12 is locked by the locking member 13, the baffle 12 forms a portion of the side wall of the cylinder 11. When the locking member 13 releases the baffle 12, the baffle 12 rotates about an axis on one side of the baffle 12, thereby opening the installation cavity 14 from the side of the air duct 1, thereby driving the blower and exhaust fan 22 out of the installation cavity 14 to facilitate maintenance by the operator.

[0026] In one example, the motor 21 is a flameproof motor 21. It is understandable that coal mines usually contain combustible gases such as methane. By designing the motor 21 as a flameproof motor 21, the safety of the mine ventilation device can be improved.

[0027] Optionally, the exhaust assembly 2 also includes a support frame 23, which includes a fixed frame 231 and a plurality of brackets 232. The fixed frame 231 is detachably connected to the motor 21, and the plurality of brackets 232 are arranged on the baffle 12 at intervals along the circumference of the baffle 12, and the plurality of brackets 232 are all connected to the fixed frame 231. It can be understood that in order to facilitate the fixing of the motor 21, the support frame 23 can be provided in the mounting cavity 14. In the embodiment of the present application, the brackets 232 are arranged on the baffle 12 at intervals along the circumference of the baffle 12, and the plurality of brackets 232 are all connected to the fixed frame 231, which can improve the bearing capacity of the support frame 23 and make the structural strength of the support frame 23 higher. Since the fixed frame 231 is detachably connected to the motor 21, it is convenient for the operator to separate the motor 21 from the fixed frame 231 to facilitate the disassembly and assembly of the motor 21.

[0028] In some embodiments, a first lug 113 is provided on the barrel 11, and a second lug 121 is provided on the other side of the baffle 12. The locking member 13 includes a threaded rod 131 and a butterfly nut 132. One end of the threaded rod 131 is pivotally connected to the first lug 113, and the rotation plane of the threaded rod 131 is orthogonal to the axial direction of the barrel 11. The other end of the threaded rod 131 is threadedly engaged with the butterfly nut 132. When the locking member 13 locks the baffle 12 and the barrel 11, the threaded rod 131 passes through the second lug 121, and the butterfly nut 132 abuts against the side of the second lug 121 facing away from the first lug 113. When the locking member 13 releases the baffle 12, the locking member 13 separates from the second lug 121. This allows the operator to open or close the air duct 1 without using external disassembly tools, improving the operator's convenience during maintenance.

[0029] In other examples, the locking member 13 may be a threaded member that is threadedly disposed on the first ear seat 113 and the second ear seat 121 to lock the cylinder 11 and the baffle 12 .

[0030] Optionally, the air guide duct 1 further includes air guide blades 15, which are disposed at the air outlet 112 and opposite the exhaust fan 22. The air guide blades 15 are detachably connected to the cylinder 11. For example, the air guide blades 15 are axial flow blades, thereby increasing the wind force of the mine ventilation device. Optionally, the air guide blades 15 are fixed blades, that is, the air guide blades 15 are fixed relative to the cylinder 11.

[0031] Optionally, the outer circumferential walls of the cylinder 11 and the baffle 12 are both provided with a plurality of reinforcing ribs 16, which are spaced apart along the axial direction of the air duct 1. This can improve the structural strength of the air duct 1 and extend its service life.

[0032] In the example of the present application, multiple circles of transverse reinforcing ribs 16 are arranged at equal intervals and are connected in series through the longitudinal reinforcing ribs 16 to further improve the structural strength of the air guide duct 1.

[0033] Furthermore, the air duct 1 further includes a dustproof net, which is provided at the air inlet 111 and detachably connected to the cylinder body 11. It is understandable that the dustproof net can prevent impurities from being sucked into the air inlet 111, thereby improving the reliability of the motor 21.

[0034] For example, the dust screen can be mounted on the cylinder 11 by means of bolts.
