Description

Technical Field

[0001] This utility model relates to the field of ventilation technology, specifically a booster tunnel ventilation fan. Background Technology

[0002] Tunnel ventilation fans, also known as tunnel jet fans, are widely used in water conservancy dam projects, highways, railways, subways and other tunnels. Tunnels are excavated and excavated in mountains or underground. A large amount of dust is generated during the excavation process, so tunnel ventilation fans are needed to replace the air. Due to the narrow space in tunnels, small-sized but high-powered special tunnel ventilation fans are required for dust treatment.

[0003] An existing patent (publication number: CN205937163U) discloses a booster tunnel ventilation fan, which consists of a fan duct, a horizontal three-phase motor, an impeller, and a fan housing. The horizontal three-phase motor has removed the cooling cover and fan fan, and is mounted on a horizontal plate on the fan duct that holds the motor. The impeller is mounted on the motor shaft, specifically on the shaft at the end where the fan was originally installed. In developing this utility model, the inventors discovered the following problems with the existing technology: 1. Existing tunnel ventilation fans are mostly fixed structures after installation, making it impossible to adjust the horizontal angle of the ventilation fan according to the user's needs. When the installation angle of the tunnel ventilation fan is tilted, it needs to be disassembled and reinstalled, significantly reducing the convenience of use; 2. Existing tunnel ventilation fan filters are usually directly fixed to the fan with bolts. When the filter needs to be removed for cleaning or maintenance, various auxiliary tools are required for disassembly, which is not only cumbersome but also significantly increases the labor intensity of workers, thus greatly reducing the practicality of the tunnel ventilation fan.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 4 This utility model provides a technical solution: a booster tunnel ventilation fan, including a housing assembly 1. A threaded rod 2 is mounted on the bottom center of the housing assembly 1 via a shaft. A threaded sleeve 3 is mounted on the outside of the threaded rod 2. Guide blocks 4 are mounted on both sides of the threaded sleeve 3. Guide rods 5 parallel to the threaded rod 2 pass through the interior of the two guide blocks 4. Two support plates 6 are mounted on the bottom of the threaded sleeve 3. A limit rod 7 is mounted between the two support plates 6. A second triangular positioning seat 8 is movably connected to the outside of the limit rod 7. A tunnel ventilation fan body 9 is mounted on the bottom of the second triangular positioning seat 8. Several slots 10 are opened on one side of the tunnel ventilation fan body 9. Insert blocks 11 are mounted inside the slots 10. A circular fixing seat 12 is provided on one side of several insert blocks 11. A filter screen 13 is provided on the side of the circular fixing seat 12 away from the insert block 11. Several boxes 14 are provided on the outside of the tunnel fan body 9. Slide grooves 15 are opened on the two inner walls of several boxes 14. Threaded control rods 16 are threadedly connected to the top of several boxes 14. The bottom of several threaded control rods 16 is connected to the middle of the top of the moving block 17 through a bearing. Slider blocks 18 are provided at both ends of several moving blocks 17. Locking rods 19 are provided at the bottom of several moving blocks 17. Springs 20 are provided on the outside of the top of several moving blocks 17. Several locking grooves 21 are opened on the outside of several insert blocks 11.

[0021] In this embodiment, as Figure 1 As shown, the housing assembly 1 includes a mounting base 101, in which a motor 102 is embedded. A U-shaped mounting plate 103 is provided on one side of the bottom end of the mounting base 101. A positioning rod 104 is provided between the two inner walls of the U-shaped mounting plate 103. A first triangular positioning seat 105 is movably connected to the outside of the positioning rod 104.

[0022] In this embodiment, as Figure 2 As shown, the first triangular positioning seat 105 rotates around the central axis of the positioning rod 104, and the second triangular positioning seat 8 rotates around the central axis of the limiting rod 7; this allows for rapid adjustment of the horizontal angle of the tunnel fan body 9 according to the user's needs, and ensures optimal operation when the fan is parallel to the tunnel, significantly improving the ventilation effect of the tunnel fan body 9, thereby greatly increasing the practicality and efficiency of the booster tunnel fan.

[0023] In this embodiment, as Figure 4 As shown, the guide rod 5 and the guide block 4 are connected by a sliding connection; this makes the threaded sleeve 3 move in a single direction, preventing the threaded sleeve 3 from rotating with the rotation of the threaded rod 2 during movement, thereby increasing the stability of the threaded sleeve 3 during movement.

[0024] In this embodiment, as Figure 2 As shown, the housing 14 and the threaded control rod 16 are symmetrical about the central axis of the tunnel fan body 9; this enables the rapid disassembly and replacement of the filter screen 13, greatly improving the convenience of disassembly, cleaning or maintenance of the filter screen 13, reducing the labor intensity of workers, and thus meeting the requirements of the booster tunnel fan.

[0025] In this embodiment, as Figure 3 As shown, the internal dimensions of several slots 10 are consistent with the external dimensions of the insert block 11; this prevents the circular fixing base 12 from rotating during use, thereby improving the stability of the circular fixing base 12 during use.

[0026] In this embodiment, as Figure 3 As shown, the slider 18 and the groove 15 are connected by a sliding connection; this increases the stability of the moving block 17 during movement, thereby preventing the moving block 17 from rotating with the rotation of the threaded control rod 16 during movement.

[0027] The usage method and advantages of this utility model: When this type of booster tunnel ventilation fan is in use, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the tunnel ventilation fan body 9 is first fixedly installed in the designated position using the mounting base 101. When the filter screen 13 needs to be disassembled, cleaned, or replaced, the four threaded control rods 16 are rotated counterclockwise. At this time, the four threaded control rods 16 drive the moving block 17 to move towards the top of the inside of the housing 14 with the cooperation of the sliding groove 15 and the slider 18. At the same time, the moving block 17 drives the locking rod 19 to move towards the top of the inside of the housing 14. At this time, the moving block 17 compresses the spring 20 until the locking rod 19 disengages from the inside of the locking groove 21, and the locking structure between the locking rod 19 and the locking groove 21 is released. Then, the circular fixing base 12 is pulled to one side of the tunnel ventilation fan body 9, so that the insert block 11 disengages from the inside of the slot 10, realizing the quick disassembly and replacement of the filter screen 13, greatly improving the efficiency of disassembly, cleaning, or maintenance of the filter screen 13. The ease of operation reduces the workload of staff, thus meeting the requirements of booster tunnel ventilation fans. When the horizontal angle of the tunnel ventilation fan body 9 needs to be adjusted, the motor 102 is started by the controller. At this time, the motor 102 drives the threaded rod 2 to rotate. The threaded rod 2 drives the threaded sleeve 3 to move downward with the cooperation of the guide block 4 and the guide rod 5. At the same time, the threaded sleeve 3 drives the limit rod 7 to move downward synchronously through the two support plates 6. This allows the horizontal angle of the tunnel ventilation fan body 9 to change slowly with the cooperation of the limit rod 7 and the second triangular positioning seat 8. This enables rapid adjustment of the horizontal angle of the tunnel ventilation fan body 9 according to the user's needs, and optimizes the working state when the fan is parallel to the tunnel. This greatly improves the ventilation effect of the tunnel ventilation fan body 9, thereby greatly increasing the practicality and efficiency of the booster tunnel ventilation fan.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
