It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] See also Figure 1-4The present utility model provides a technical solution: a ventilation device for mining, comprising a ventilation fan 1, one end of which is connected to a ventilation pipe 2, the surface of which is sheathed with an access pipe 3. A top block A4 is fixedly mounted on the top surface of the ventilation pipe 2, and a top block B5 is fixedly mounted on the top surface of the access pipe 3. The ventilation pipe 2 and the access pipe 3 are connected by bolts or welding, ensuring the stability and airtightness of the connection and preventing water seepage and air leakage. The top block A4 and the top block B5 are connected by a sliding connection. A threaded rod 6 extends through the top block A4. The top block B5 is internally threaded, and the threads engage with the threaded rod 6. This threaded connection allows the threaded rod 6 to rotate smoothly, driving the top block B5 and the access pipe 3 to slide on the surface of the ventilation pipe 2, thereby achieving precise fine-tuning of the access pipe 3. A screw cap 9 is fixedly mounted on one end of the threaded rod 6. The screw cap 9 has a hexagonal structure and is easy to operate. By turning the screw cap 9, a worker can rotate the threaded rod 6, which in turn moves the top block B5, thereby adjusting the length of the access pipe 3. The threaded connection not only precisely controls the sliding movement but also ensures the flexibility of ventilation equipment adjustment at different mine depths.

[0025] See also Figure 1-4 A bending block 7 is fixedly installed on the surface of the access pipe 3. The material of the bending block 7 can be stainless steel or aluminum alloy to ensure its corrosion resistance and service life. A friction disc 8 is fixedly installed on the inner side of the bending block 7. The surface of the friction disc 8 is polished with 40-mesh sandpaper to provide greater friction. When adjusting the access pipe 3, the friction disc 8 fits against the surface of the ventilation pipe 2, and an abnormal sound is generated through friction to remind the staff that the adjustment operation is in progress. This physical feedback method can not only avoid misoperation due to negligence, but also improve safety through simple and effective sound feedback. The material of the friction disc 8 can be selected from wear-resistant rubber or polyurethane to ensure that it is not easily damaged during long-term use, and at the same time can effectively reduce the maintenance cost of the equipment.

[0026] Example 2

[0027] See also Figure 3-4The side of the ventilation fan 1 is provided with an auxiliary mechanism, which includes a rotating rod 10. The rotating rod 10 is rotatably connected to the side of the ventilation fan 1 by a bearing to ensure smooth and low friction during rotation and extend the service life of the equipment. A long plate 11 is fixedly installed on the surface of the rotating rod 10, and brush plates 12 are symmetrically distributed on the side of the long plate 11. The long plate 11 can be made of aluminum alloy or carbon fiber to ensure its lightness and do not affect the balance and durability during rotation. The brush plate 12 fits well with the surface of the ventilation fan 1. The brush plate 12 can be made of nylon or polyurethane, which can effectively remove dust from the surface of the ventilation fan 1 and prevent dust accumulation from affecting the heat dissipation and ventilation efficiency of the equipment. A rotating cap 13 is fixedly installed at one end of the rotating rod 10, and a rubber column 14 is fixedly installed on the side of the rotating cap 13. The material of the rubber column 14 is natural rubber with good elasticity and wear resistance. The rubber column 14 fits well with the surface of the ventilation fan 1 and can control the limit of the brush plate 12 through friction to avoid abnormal noise caused by tampering when not in use.

[0028] Working principle: air is taken in through the ventilation fan 1, and then the air is connected to the mine through the ventilation pipe 2 and the access pipe 3. At this time, ventilation can be carried out. The length of the ventilation pipe 2 can be adjusted according to the depth of the mine, and the access pipe 3 at the tail end can be fine-tuned. This can better adapt to the depth of the mine and avoid water seepage caused by the access pipe 3 being too short. During the installation process, if the access pipe 3 is longer or shorter at the end, the staff only needs to twist the screw cap 9, and the screw cap 9 can then drive the threaded rod 6 to rotate. At this time, since there is a thread in the top block B5, the threaded rod 6 can drive the top block B5 to move, and the top block B5 can then drive the access pipe 3 to slide on the surface of the ventilation pipe 2. At this time, the position of the access pipe 3 can be adjusted. , so as to better adapt to the depth of the mine. At the same time, in the process of adjusting the access pipe 3, the access pipe 3 can drive the bending block 7 to move, and the bending block 7 can drive the friction disk 8 to move. The friction disk 8 can rub the surface of the ventilation pipe 2. Since the surface of the friction disk 8 is polished with 40-grit sandpaper and is relatively rough, a large abnormal noise can be emitted when rubbing the ventilation pipe 2. This abnormal noise can remind the staff that the length is being adjusted. The utility model provides an adjustable-length ventilation pipe 2, so that the equipment can be flexibly adjusted according to the specific depth of the mine, can adapt to different mine environments, ensure the effectiveness and adaptability of ventilation, and avoid low efficiency or installation difficulties caused by length mismatch. By twisting the cap 9 and the threaded rod 6 The design allows workers to quickly and easily adjust the position of the access pipe 3, making the installation process more efficient. This mechanical adjustment method simplifies the operation, reduces installation time, and improves work efficiency. At the same time, the abnormal noise generated by the designed friction disk 8 serves as a feedback mechanism, which can immediately remind workers to adjust the status. This physical feedback method can prevent negligence during operation, ensure the accuracy of operation, and improve safety. During the long-term operation of the ventilation fan 1, if too much dust accumulates at the air inlet, the worker can rotate the rotating cap 13 to rotate the rotating rod 10 during maintenance. The rotating rod 10 can then drive the long plate 11 to rotate, and the long plate 11 can then drive the brush plate 12 to rub the surface of the ventilation fan 1. , so that dust can be removed, and the friction between the rubber column 14 and the ventilation fan 1 can limit the brush plate 12 to avoid abnormal noise caused by turbulence when not in use. The utility model can directly drive the brush plate 12 to clean the dust on the surface of the ventilation fan 1 through manual rotation operation. This design makes the maintenance and cleaning process simpler and faster. The staff does not need to disassemble the ventilation fan 1 or use other tools, and can directly complete the cleaning task through mechanical operation, saving time and labor costs. Regularly and conveniently removing dust from the ventilation fan 1 can maintain the efficiency of the fan. At the same time, through this built-in cleaning mechanism, mechanical failures caused by dust accumulation can be prevented, the service life of the equipment can be extended, and the number of maintenance times and costs can be reduced.
