Description

Technical Field

[0001] The utility model relates to the technical field of mining, and specifically relates to a mine fan diffuser. Background Technique

[0002] In mine operations, a good ventilation system is one of the key factors to ensure safe production. There are flammable and explosive substances such as gas and dust in the mine, as well as harsh environmental conditions such as high temperature and high humidity that may occur. Effective ventilation can timely discharge these harmful gases and dust, reduce the gas concentration, adjust the underground temperature and humidity, and provide a safe and comfortable working environment for miners.

[0003] At present, in the prior art, the mine environment is relatively enclosed, and noise will continuously reflect and superimpose in a limited space, resulting in a further increase in the noise level. This will not only cause serious damage to the hearing of miners, but also may lead to occupational diseases such as tinnitus, hearing loss, and neurasthenia for miners who are in a high-noise environment for a long time. In view of this, we propose a mine fan diffuser. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a mine fan diffuser that can solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the mine fan diffuser proposed by the utility model includes a base, the outer wall of the base is fixedly connected with a diffusion cylinder, a mine fan is fixedly connected to the inner wall of the diffusion cylinder, a support structure is arranged on the connecting flange of the outer wall of the diffusion cylinder, and a sound-absorbing structure is arranged on the support structure. The support structure includes:

[0006] A fixed seat, the connecting flange is fixedly connected with a fixed seat, the inner wall of the fixed seat is fixedly connected with a mounting frame, a micro motor is arranged in the mounting frame, the output shaft of the micro motor is fixedly connected with a driving rod, and the driving rod penetrates through the mounting frame and is fixedly connected with a rotating gear;

[0007] A first rotating plate, the rotating gear is fixedly connected with the first rotating plate, the first rotating plate is slidably connected to the outer wall of the mounting frame, the rotating gear is meshed with a driven gear, and the driven gear is fixedly connected with a second rotating plate;

[0008] An adapter plate, the mounting frame is rotatably connected with an adapter plate, there are two groups of the adapter plates, and the ends of the two groups of adapter plates away from the mounting frame are respectively rotatably connected to a first hinge plate and a second hinge plate;

[0009] A clamping block, the second hinge plate is fixedly connected with the clamping block.

[0010] Preferably, the sound insulation structure includes a flip plate which is rotatably connected to the clamping block. Through the rotational connection with the clamping block, the flip plate can flexibly adjust its angle to meet different installation requirements.

[0011] Preferably, a chute is formed on the surface of the flip plate, and a threaded block is arranged on the chute. The chute provides a moving track for the threaded block, restricting the moving direction of the threaded block so that it can only slide on a specific path.

[0012] Preferably, a threaded rod is threadedly connected to the threaded block, and the threaded rod is arranged in the chute. Rotating the threaded block causes the threaded rod to gradually approach the inner wall of the diffusion cylinder to achieve extrusion and limitation.

[0013] Preferably, a limiting plate is fixedly connected to the side of the threaded rod close to the inner wall of the diffusion cylinder. The limiting plate presses the sound insulation cotton against the inner wall of the diffusion cylinder. The limiting plate will approach the inner wall of the diffusion cylinder as the threaded rod moves, pressing the sound insulation cotton so that the sound insulation cotton fits tightly against the inner wall of the diffusion cylinder to ensure the sound insulation effect.

[0014] Preferably, a fillet is formed at the connection between the fixed seat and the connecting flange, effectively preventing the staff from accidentally bumping and getting injured during the operation, reflecting the care and consideration for the safety of the staff.

[0015] The utility model provides a mine fan diffuser, which has the following beneficial effects:

[0016] (1) Through the set support structure of the mine fan diffuser, the rotation of the output shaft is driven by the operation of the micro motor. During the rotation of the driving rod, the rotation of the rotating gear is driven, and the rotating gear rotates with the driven gear, thereby driving the movement of the first rotating plate and the second rotating plate to adjust the angular position in the arc-shaped groove, thereby driving the synchronous movement of the first hinged plate and the second hinged plate, driving the first hinged plate and the second hinged plate to clamp the connecting flange. The concavities and convexities on the clamping block increase the friction to prevent slipping, facilitating the connection of the sound insulation structure and ensuring that no damage will occur during the working process.

[0017] (2) Through the set sound insulation structure of the mine fan diffuser, the sound insulation cotton is placed between the inner wall of the diffusion cylinder and the flip plate. By moving the threaded rod, the position of the threaded block is adjusted in the chute. Rotating the threaded block causes the threaded rod to gradually approach the diffusion cylinder, thereby driving the limiting plate to move towards the inner wall of the diffusion cylinder. The limiting plate gradually presses the sound insulation cotton, making the sound insulation cotton fit tightly against the inner wall of the diffusion cylinder. When the mine fan is working, the air flow passes through the diffusion cylinder, and the sound insulation cotton can effectively absorb and scatter noise, reducing the noise level and improving the comfort and safety of the working environment.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Please refer to Figures 1 - 5, the present utility model proposes a diffuser for a mine fan, which includes a base 1. The outer wall of the base 1 is fixedly connected with a diffuser cylinder 2. The inner wall of the diffuser cylinder 2 is fixedly connected with a mine fan 3. When the mine fan 3 operates, the high-speed air flow generated enters the diffuser through a pipeline. Since the cross-sectional area of the diffuser cylinder 2 gradually increases, the air flow speed gradually decreases. A support structure 4 is arranged on the connecting flange of the outer wall of the diffuser cylinder 2, and a sound-absorbing structure 5 is arranged on the support structure 4. The support structure 4 includes a fixed seat 41.

[0029] In an embodiment of the present utility model, in order to be able to connect the sound-absorbing structure 5 and ensure that no damage occurs during the working process, specifically, a fixed seat 41 is fixedly connected to the connecting flange. A fillet is provided at the connection between the fixed seat 41 and the connecting flange, effectively preventing the staff from accidentally bumping and getting injured during the operation process, reflecting the care and consideration for the safety of the staff. The inner wall of the fixed seat 41 is fixedly connected with a mounting frame 42. A micro motor is arranged in the mounting frame 42. The output shaft of the micro motor is fixedly connected with a driving rod 43. The driving rod 43 penetrates through the mounting frame 42 and is fixedly connected with a rotating gear 44. By the operation of the micro motor, the output shaft rotates. During the rotation of the driving rod 43, the rotating gear 44 is driven to rotate. The rotating gear 44 is fixedly connected with a first rotating plate 45. The first rotating plate 45 is slidably connected to the outer wall of the mounting frame 42. The rotating gear 44 is meshed with a driven gear 46. The driven gear 46 is fixedly connected with a second rotating plate 47. By the rotation of the rotating gear 44 and the driven gear 46, the first rotating plate 45 and the second rotating plate 47 are driven to adjust the angular position in the arc-shaped groove during the movement. A connecting plate 48 is rotatably connected to the mounting frame 42. There are two groups of connecting plates 48. The ends of the two groups of connecting plates 48 away from the mounting frame 42 are respectively rotatably connected to a first hinge plate 49 and a second hinge plate 410. The connecting plate 48 assists the stable movement of the first hinge plate 49 and the second hinge plate 410. The second hinge plate 410 is fixedly connected with a clamping block 411. Through the synchronous movement of the first hinge plate 49 and the second hinge plate 410, the first hinge plate 49 and the second hinge plate 410 are driven to clamp the connecting flange. The unevenness on the clamping block 411 increases the friction force to prevent slipping, facilitating the connection of the sound-absorbing structure 5.

[0030] Further, in order to reduce the noise level and improve the comfort and safety of the working environment, specifically, the sound insulation structure 5 includes a flip plate 51. The flip plate 51 is rotatably connected to the clamping block 411. Through the rotational connection with the clamping block 411, the flip plate 51 can flexibly adjust the angle to adapt to different installation requirements. A chute 52 is provided on the surface of the flip plate 51, and a threaded block 53 is arranged on the chute 52. The chute 52 provides a moving track for the threaded block 53 and limits the moving direction of the threaded block 53, enabling it to slide only on a specific path. A threaded rod 54 is threadedly connected to the threaded block 53, and the threaded rod 54 is arranged in the chute 52. Rotating the threaded block 53 causes the threaded rod 54 to gradually approach the inner wall of the diffusion cylinder 2 to achieve extrusion and limitation. A limiting plate 55 is fixedly connected to the side of the threaded rod 54 close to the inner wall of the diffusion cylinder 2. The limiting plate 55 presses the sound insulation cotton 56 close to the inner wall of the diffusion cylinder 2. The limiting plate 55 will approach the inner wall of the diffusion cylinder 2 and press the sound insulation cotton 56 as the threaded rod 54 moves, making the sound insulation cotton 56 closely adhere to the inner wall of the diffusion cylinder 2 to ensure the sound insulation effect. First, place the sound insulation cotton 56 between the inner wall of the diffusion cylinder 2 and the flip plate 51. By moving the threaded rod 54, adjust the position of the threaded block 53 in the chute 52. Rotate the threaded block 53 to make the threaded rod 54 gradually approach the diffusion cylinder 2, thereby driving the limiting plate 55 to move towards the inner wall of the diffusion cylinder 2. The limiting plate 55 gradually presses the sound insulation cotton 56, making the sound insulation cotton 56 closely adhere to the inner wall of the diffusion cylinder 2. When the mine fan 3 is working, the air flow passes through the diffusion cylinder 2, and the sound insulation cotton 56 can effectively absorb and scatter noise, reducing the noise level and improving the comfort and safety of the working environment.

[0031] In the present utility model, during use, the rotation of the output shaft is driven by the operation of the micro motor. During the rotation of the driving rod 43, the rotation of the rotating gear 44 is driven. The rotating gear 44 rotates with the driven gear 46, thereby driving the movement of the first rotating plate 45 and the second rotating plate 47 to adjust the angular position in the arc-shaped groove during the movement, thereby driving the synchronous movement of the first articulated plate 49 and the second articulated plate 410, driving the first articulated plate 49 and the second articulated plate 410 to clamp the connecting flange. The unevenness on the clamping block 411 increases the friction force to prevent slipping, facilitating the connection of the sound insulation structure 5. Place the sound insulation cotton 56 between the inner wall of the diffusion cylinder 2 and the flip plate 51. By moving the threaded rod 54, adjust the position of the threaded block 53 in the chute 52. Rotate the threaded block 53 to make the threaded rod 54 gradually approach the diffusion cylinder 2, thereby driving the limiting plate 55 to move towards the inner wall of the diffusion cylinder 2. The limiting plate 55 gradually presses the sound insulation cotton 56, making the sound insulation cotton 56 closely adhere to the inner wall of the diffusion cylinder 2. When the mine fan 3 is working, the air flow passes through the diffusion cylinder 2, and the sound insulation cotton 56 can effectively absorb and scatter noise, reducing the noise level and improving the comfort and safety of the working environment.

[0032] The above are only the preferred embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
