Description

Technical Field

[0001] This utility model relates to a ventilation device, and more particularly to a novel mine ventilation structure, belonging to the technical field of ventilation equipment. Background Technology

[0002] After tunneling, ventilation systems are needed to ventilate the mine. Common ventilation systems include fans and ventilation ducts connected to the fan's outlet. Existing ventilation ducts are often simply fitted onto the outer wall of the fan outlet and then secured with wire by workers. This method is prone to detachment, and the ducts are easily damaged by shaking and friction against the fan's outer wall during unstable airflow, such as when the fan is turned on or off. Furthermore, the current method of installing ventilation ducts in the mine often involves setting up a steel wire rope along the mine's direction at the top of the tunnel and then hanging the duct on the rope. Workers often directly wrap the wire around the duct during installation, which is inconvenient for both installation and removal. Moreover, the wire often leaves sharp points after installation, which can easily tear the duct and cause leaks when the airflow vibrates.

[0003] Therefore, this utility model proposes a new solution. Utility Model Content

Detailed Implementation

[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0027] like Figures 1-6 As shown, the novel mine ventilation structure provided in this embodiment includes a fan 1 and a ventilation duct 2. An installation mechanism for connecting the ventilation duct 2 to the air outlet of the fan 1 is provided between the fan 1 and the ventilation duct 2. The installation mechanism includes a connecting cylinder 3 that is detachably connected to the air outlet of the fan 1. A partition plate 4 is fixedly connected to the outer wall of the connecting cylinder 3. The tube cloth of the ventilation duct 2 is sleeved on the outer wall of the connecting cylinder 3, and one end is covered by the partition plate 4. Two clamps 5 connected by bolts 6 are installed on the outside of the connecting cylinder 3. An elastic hook 8 that is hung on a steel wire rope 7 is installed on the ventilation duct 2. By setting up the installation mechanism, the air duct 2 is sleeved onto the outer wall of the connecting cylinder 3 and one end of it is covered by the partition plate 4. Then, two clamps 5 are installed on the outside and tightened with bolts 6, which can install and fix the air duct 2. Due to the cooperation between the connecting cylinder 3 and the clamps 5, the air duct 2 can be prevented from falling off and can also prevent the air duct 2 from rubbing against the connecting cylinder 3 when vibrating, thereby preventing wear. The setting of the elastic hook 8 makes it easy to connect and disassemble the air duct 2 and the wire rope 7, and can also prevent the air duct 2 from being scratched or damaged.

[0028] In this embodiment, as Figure 1 and Figure 3As shown, the clamp 5 includes a ring plate 501 and a retaining ring 502 fixedly connected to one end of the ring plate 501. The ring plate 501 is installed on the outer wall of the connecting cylinder 3. The inner side of the retaining ring 502 has a retaining groove 503 that mates with the partition plate 4. Mounting plates 504 are fixedly connected to both the upper and lower ends of the clamp 5. The mounting plates 504 have mounting holes 505 that mate with the bolts 6. Through the arrangement of the ring plate 501 and the retaining ring 502, and the retaining ring 502 having a retaining groove 503 that mates with the partition plate 4, it can cooperate with the partition plate 4 to fix the air duct 2 cloth and prevent it from falling off. The ring plate 501 presses the air duct 2 cloth located on the outer wall of the connecting cylinder 3 tightly against the outer wall of the connecting cylinder 3, so that the air duct 2 will not rub against the connecting cylinder 3 when it vibrates, thereby preventing wear.

[0029] In this embodiment, as Figure 1 and Figure 4 As shown, a hanging cloth 9 is connected to the top of the air duct 2. The hanging cloth 9 has several evenly spaced hanging holes 10 that connect to the elastic hooks 8. The elastic hooks 8 include a torsion spring 801, with hooks 802 connected to both ends of the torsion spring 801. The torsion spring 801 of the elastic hook 8 is installed in the hanging holes 10. When suspended, the two hooks 802 are pulled respectively, causing both hooks 802 to be hooked onto the wire rope 7. This prevents the air duct 2 from falling off and allows for convenient and quick installation and removal. Since both hooks 802 are positioned inwards, they will not come into contact with the air duct 2 when it vibrates, preventing scratches.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, flanges 11 are fixedly connected to the sides of the connecting cylinder 3 and the fan 1 that are close to each other, and the two flanges 11 are connected by bolts. The connecting cylinder 3 and the fan 1 are detachably connected by bolts.

[0031] In this embodiment, as Figure 1 , Figure 5 and Figure 6As shown, a fixed frame 12 is fixedly connected to the outer wall of the fan 1. Suspension mechanisms 13 are installed at each of the four corners of the fixed frame 12. Each suspension mechanism 13 includes a fixed plate 14 mounted on the top of the mine tunnel by expansion bolts. An adjusting frame 15 is located below the fixed plate 14. A screw rod 16, threadedly connected to the adjusting frame 15, is rotatably mounted on the fixed frame 12. A screw hole 17, cooperating with the screw rod 16, is opened at the bottom of the adjusting frame 15. A through hole 18, rotatably cooperating with the screw rod 16, is opened on the fixed frame 12. The bottom end of the screw 16 is fixedly connected to a handle 19 located below the fixed frame 12. Multiple nuts 20 located inside the adjusting frame 15 are threaded onto the outer wall of the screw 16. Fixed holes 21 are provided at both ends of the fixed plate 14. A sliding rod 22, which is slidably connected to the fixed plate 14, is fixedly connected to the top of the adjusting frame 15. A sliding hole 23, which mates with the sliding rod 22, is provided in the middle of the fixed plate 14. A top plate 24 is connected to the top of the sliding rod 22, and a damping spring 25 is provided between the top plate 24 and the fixed plate 14. By installing suspension mechanisms 13 at each of the four corners of the fixed frame 12, the fan 1 can be stably supported. By setting the adjusting frame 15 and the screw 16, the lengths of the four suspension mechanisms 13 can be adjusted respectively, thereby adjusting the height and level of the fan 1. Nuts 20 are provided to prevent stripping of the screw holes 17.

[0032] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the novel mine ventilation structure provided in this embodiment is as follows:

[0033] When installing the air duct 2, pull out one end of the air duct 2 and fit it onto the outer wall of the connecting tube 3, and cover one end of it with the partition plate 4. Then install the two clamps 5 on the outside and install the slots 503 on the partition plate 4. Then tighten them with bolts 6. When suspending the air duct 2, pull the two hooks 802 respectively so that both hooks 802 are hooked on the wire rope 7. Then release the hooks 802.

[0034] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
