Description

Technical Field

[0001] This utility model relates to the field of ventilation equipment technology, and in particular to a ventilation device for tunnels that is easy to install. Background Technology

[0002] Tunnel construction ventilation refers to supplying fresh air to the tunnel interior; removing harmful gases, vapors, dust, and fumes; and ensuring that the temperature, relative humidity, and airflow velocity of the air inside the tunnel meet specified standards. In practical applications, ventilation equipment typically requires the following technologies:

[0003] 1. A ventilation fan converts mechanical energy into the kinetic and pressure energy of air through the rotation of its impeller, causing air to flow in the ventilation system;

[0004] 2. Ventilation ducts are used to change the direction, branches, and diameter of the ducts, enabling the ventilation system to adapt to different layouts and needs;

[0005] Currently, existing ventilation equipment (such as patent publication number: CN217421245U) discloses an energy-saving ventilation and air exchange device for tunnel construction. By setting the air quality detection module in the tunnel, it can effectively realize real-time monitoring of the air quality inside the tunnel, making the detection results more accurate. By setting the ventilation and air exchange device in the vertical shaft of the tunnel, the chimney effect, that is, the pressure difference between the inside and outside airflow, can be used to accelerate the air convection between the inside and outside of the tunnel, which is beneficial for exhaust or ventilation.

[0006] Blades are usually fixed directly to the hub with bolts or rivets. During installation and disassembly, each bolt needs to be aligned and then the knobs turned. However, the distance between the blades and the fan housing is small. During the installation process, it takes a long time to align each bolt, resulting in a slow disassembly and installation speed. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a convenient ventilation device for tunnels, solving the technical problem that during installation and disassembly, it is necessary to align each bolt individually and then turn the knob. However, the distance between the blades and the fan housing is small, and it takes a long time to align each bolt individually during installation, resulting in slow disassembly and installation speed.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A conveniently installed ventilation device for tunnels includes a fan body. At least two mounting brackets are fixedly installed inside the fan body. A blade body is rotatably mounted on the side end of each mounting bracket. An installation sleeve is fixedly mounted on the side end of each blade body. Two guide rods are fixedly mounted on the side end of each installation sleeve. A base is fixedly installed inside each mounting bracket. A synchronization ring is rotatably mounted on the top of each base.

[0012] Preferably, each of the synchronization rings has a U-shaped plate slidably mounted on its side end, each of the U-shaped plates has a fixing rod rotatably mounted on its side end, each of the U-shaped plates has two return springs fixedly mounted on its side end, each of the mounting sleeves has two positioning grooves on its outer surface, and each of the bases has a drive shaft rotatably mounted inside, with the top end of the drive shaft docking with the side end of the blade body.

[0013] (III) Beneficial Effects

[0014] 1. By moving the blade body, the side end of the mounting sleeve is aligned with the synchronizing ring. After the mounting sleeve and the synchronizing ring are in contact, the side end of the U-shaped plate aligns with the positioning hole on the outside of the mounting sleeve. The protrusion on one side of the U-shaped plate aligns with the mounting sleeve. At the same time, the return spring exerts a pulling force on the U-shaped plate, making the U-shaped plate tightly adhere to the side end of the mounting sleeve. Then, by rotating the fixing rod, the end of the fixing rod is rotated into the interior of the synchronizing ring to fix the position of the U-shaped plate, thus completing the docking device between the blade body and the synchronizing ring, which facilitates the replacement of the blade body.

[0015] 2. By moving the blade body, the side end of the mounting sleeve is aligned with the synchronizing ring. The guide rod is inserted into the side end of the synchronizing ring, and the mounting sleeve is aligned with the synchronizing ring. The mounting sleeve is then pushed to fit and align with the side end of the synchronizing ring. In the case of multiple disassembly and reassembly, the guide rod helps to maintain the consistency of each reassembly and improves the accuracy of repeated reassembly. Attached Figure Description

[0022] This application provides a convenient ventilation device for tunnel installation, effectively solving the problem that during installation and disassembly, it is necessary to connect each bolt individually and then turn the knob. However, the distance between the blades and the fan housing is small, and it takes a long time to connect each bolt individually during installation, resulting in slow installation and disassembly. By moving the blade body, the side end of the mounting sleeve is aligned with the synchronization ring. After the mounting sleeve and the synchronization ring are in contact, the side end of the U-shaped plate aligns with the positioning hole on the outside of the mounting sleeve. The protrusion on one side of the U-shaped plate aligns with the mounting sleeve, and the return spring simultaneously exerts a pulling force on the U-shaped plate, making the U-shaped plate tightly adhere to the side end of the mounting sleeve. Then, by rotating the fixing rod, the end of the fixing rod is rotated into the interior of the synchronization ring to fix the position of the U-shaped plate, completing the connection device between the blade body and the synchronization ring, which facilitates the replacement and installation of the blade body.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that during installation and disassembly, it is necessary to connect each bolt individually and then tighten the knob. However, the distance between the blades and the fan housing is small, and connecting each bolt individually during installation takes a long time, resulting in slow disassembly and installation speed. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a convenient ventilation device for tunnels, including a fan body 11. At least two mounting brackets 12 are fixedly installed inside the fan body 11. A blade body 13 is rotatably mounted on the side end of each mounting bracket 12. An installation sleeve 14 is fixedly mounted on the side end of each blade body 13. Two guide rods 15 are fixedly mounted on the side end of each installation sleeve 14. The guide rods 15 are inserted into the side end of a synchronization ring 17, and the installation sleeve 14 is aligned with the synchronization ring 17. The installation sleeve 14 is pushed to fit and connect with the side end of the synchronization ring 17. In the case of multiple disassemblies and connections, the guide rods 15 help maintain consistency in each connection and improve the accuracy of repeated connections. A base 16 is fixedly installed inside each mounting bracket 12, and a synchronization ring 17 is rotatably mounted on the top of each base 16.

[0026] Each synchronizing ring 17 has a U-shaped plate 18 slidably mounted on its side end, and a fixing rod 19 is rotatably mounted on the side end of each U-shaped plate 18. Two return springs 21 are fixedly mounted on the side end of each U-shaped plate 18. After the mounting sleeve 14 is in contact with the synchronizing ring 17, the side end of the U-shaped plate 18 aligns with the positioning hole on the outside of the mounting sleeve 14, and the protrusion on one side of the U-shaped plate 18 aligns with the mounting sleeve 14. The return springs 21 simultaneously exert a pulling force on the U-shaped plate 18, so that the U-shaped plate 18 is tightly attached to the side end of the mounting sleeve 14. Two positioning grooves are opened on the outer surface of each mounting sleeve 14. A drive shaft is rotatably mounted inside each base 16, and the top end of the drive shaft aligns with the side end of the blade body 13.

[0027] Working principle:

[0028] The first step involves installing a motor and control circuit inside the fan body 11, driving the blade body 13 to rotate inside the fixed frame 12. This converts mechanical energy into the kinetic and pressure energy of the air, causing air to flow in the ventilation system. The air is then transported from the fan to various areas through pipes, achieving air circulation and distribution. By rotating the fixed rod 19, the side end of the U-shaped plate 18 rotates. Simultaneously, the end of the fixed rod 19 is threaded, and rotation causes the end of the fixed rod 19 to rotate out of the synchronous ring 17. This is achieved by pulling... Two U-shaped plates 18 slide on the side end of the synchronization ring 17, simultaneously pulling the top end of the return spring 21, forcing the return spring 21 to stretch inside the synchronization ring 17. As the U-shaped plates 18 move, the top end of the U-shaped plates 18 leaves the side end of the mounting sleeve 14, and at the same time, by pulling the blade body 13, the mounting sleeve 14 moves synchronously, leaving the side end of the synchronization ring 17. The mounting sleeve 14 drives the guide rod 15 to leave the inside of the synchronization ring 17, allowing the mounting sleeve 14 to disconnect from the synchronization ring 17 and disassemble the blade body 13.

[0029] The second step involves moving the blade body 13 to align the side end of the mounting sleeve 14 with the synchronizing ring 17. The guide rod 15 is then inserted into the side end of the synchronizing ring 17, and the mounting sleeve 14 is aligned with the synchronizing ring 17. This pushes the mounting sleeve 14 to engage with the side end of the synchronizing ring 17. In repeated disassembly and reassembly, the guide rod 15 helps maintain consistency in each reassembly, improving the accuracy of repeated reassemblies. The moving mounting sleeve 14 rubs against the top of the U-shaped plate 18. Because the side end of the U-shaped plate 18 has a protruding design, this friction causes the U-shaped plate 18 to move, allowing the U-shaped plate... 18 slides on the side end of the synchronization ring 17. At the same time, after the mounting sleeve 14 is in contact with the synchronization ring 17, the side end of the U-shaped plate 18 aligns with the positioning hole on the outside of the mounting sleeve 14. The protrusion on one side of the U-shaped plate 18 aligns with the mounting sleeve 14. The return spring 21 simultaneously exerts a pulling force on the U-shaped plate 18, so that the U-shaped plate 18 is tightly attached to the side end of the mounting sleeve 14. Then, by rotating the fixing rod 19, the end of the fixing rod 19 is rotated into the interior of the synchronization ring 17 to fix the position of the U-shaped plate 18, thus completing the docking device between the blade body 13 and the synchronization ring 17, which facilitates the replacement and installation of the blade body 13.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
