[0030] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0031] Reference Figure 1-2 This embodiment provides a circular coal yard shutter adjustment device, including an adjustment assembly 1, which is installed in the shutter and is used to stably adjust the angle of the shutter blades. The adjustment assembly 1 includes a plurality of vertically parallel gears 11, each gear 11 being correspondingly installed on each shutter blade. The rotation of the plurality of gears 11 drives the rotation of the plurality of shutter blades, thereby achieving adjustment and fixing of the angle of the shutter blades.

[0032] A fixed shaft 12 is provided on the gear 11. Two fixed shafts 12 are symmetrically provided on the multiple gears 11 located in the middle, and the two fixed shafts 12 on each gear 11 are respectively located on both sides of the shutter blade;

[0033] A connecting rod 13 is provided between each adjacent gear 11. The two ends of the connecting rod 13 are movably connected to the upper and lower adjacent gears 11 respectively. Multiple connecting rods 13 drive multiple gears 11 to rotate synchronously, avoiding serious corrosion of the gears 11 caused by the influence of sea breeze and monsoon, which makes the rotation adjustment of the blinds blades not smooth.

[0034] As an optional embodiment, the connecting rod 13 includes a connecting rod body 131 and connecting sleeves 132 disposed at both ends of the connecting rod body 131 and rotatably connected to the fixed shaft 12. The movable connection between the connecting sleeves 132 and the fixed shaft 12 enables connection between two adjacent gears 11. Even if the gears 11 corrode and cannot mesh, transmission can still be achieved. As long as at least one gear 11 is able to mesh, stable transmission is guaranteed, reducing the likelihood of the device being affected by sea breezes and monsoon weather.

[0035] As an optional embodiment, it further includes a plurality of blades 2 and a shutter frame 3 for mounting the plurality of blades 2. The plurality of blades 2 are fixedly connected to the plurality of gears 11 in a one-to-one correspondence. Each blade 2 includes a blade body 21 and connecting shafts 22 provided at both ends of the blade body 21. Each connecting shaft 22 is connected to each gear 11, and the rotation of each gear 11 drives the rotation and fixation of each blade 2.

[0036] As an optional embodiment, the louver frame 3 is further provided with a locking bolt 31. The louver frame 3 is provided with an installation compartment 32 for installing the adjustment assembly 1. The installation compartment 32 is provided with an opening for inspection. The opening allows observation of the installation status of the adjustment assembly 1 in the installation compartment 32, facilitating inspection of the components before installation and preventing damage to the components after installation.

[0037] As an optional embodiment, the mounting plate 4 is slidably disposed in the mounting chamber 32, and two mounting plates 4 are provided side by side. Racks 5 meshing with the gear 11 are slidably disposed on both mounting plates 4. The two racks 5 are located on the side of the two mounting plates 4 away from the opening. The two racks 5 do not mesh with the gear 11 when the two mounting plates 4 are separated. When the two mounting plates 4 are opened, it is convenient to install the bolts 31. When the two mounting plates 4 are combined, the bolts 31 and the opening can be shielded and protected to prevent the sea breeze and monsoon climate from corroding the parts in the mounting chamber 32, making the installation more stable. A sealing plate 6 is provided on the mounting plate 4, and a pull plate 7 is provided on the mounting plate 4. The bolts 31 are shielded by the provided sealing plate 6, and the two mounting plates 4 can be pulled closer together by the provided pull plate 7 to seal the opening.

[0038] As an optional embodiment, a rotation assembly 8 is further included. The rotation assembly 8 includes a bidirectional screw 81 that is rotatably disposed within the mounting chamber 32, and a threaded sleeve 82 disposed on the bidirectional screw 81 and connected to each of the two mounting plates 4. A clamping assembly 9 is provided in the middle of the bidirectional screw 81 for securing the two mounting plates 4. When the two mounting plates 4 are pulled toward each other, the threaded sleeve 82 engages and rotates the bidirectional screw 81, which in turn rotates the clamping assembly 9, allowing the clamping assembly 9 to simultaneously lock the two mounting plates 4. This ensures that the two mounting plates 4 are stably sealed and locked against the opening, preventing the sea breeze and monsoon climate from affecting the components within the mounting chamber 32 through the opening.

[0039] As an optional embodiment, the clamping assembly 9 includes a mounting tube 91 disposed in the middle of the bidirectional screw 81, a fixing plate 92 disposed on the mounting tube 91, and a clamping block 93 disposed on the fixing plate 92. The rotation of the rotating assembly 8 can drive the rotation of the clamping assembly 9, thereby achieving the installation and fixation of the two mounting plates 4.

[0040] As an optional embodiment, a locking assembly 10 is further included, which includes a fixed frame 101 provided on the mounting plate 4, a ratchet 102 provided in the mounting plate 4, a limiting rod 103 provided in the mounting plate 4 and clamped with the ratchet 102, a bottom plate 104 provided on the ratchet 102 and located below the fixed frame 101, and a limiting plate 105 provided on the ratchet 102 and located above the fixed frame 101. The rotating assembly 8 drives the clamping assembly 9 to rotate, the clamping block 93 is clamped in the fixed frame 101, and the clamping block 93 pushes the bottom plate 104 downward, which drives the ratchet 102 to rotate, thereby causing the limiting plate 105 to rotate synchronously. The limiting plate 105 stably presses the upper end of the clamping block 93, thereby preventing the clamping assembly 9 from rotating and resetting, thereby achieving stable limiting of the two mounting plates 4. The mounting plate 4 is provided with a strip-shaped opening for the bottom plate 104 and the limiting plate 105 to pass through.

[0041] As an optional embodiment, the mounting plate 4 is provided with a through hole 41 for the rotation assembly 8 to pass through, and the mounting plate 4 is provided with a slide groove 42 for slidingly setting the rack 5. The rotation assembly 8 passes through the mounting plate 4 and can drive the mounting plate 4 to move. At the same time, the mounting plate 4 is stably clamped by the clamping assembly 9 and the mounting plate 4.

[0042] As an optional embodiment, it also includes an electric telescopic assembly 14 disposed on one of the mounting plates 4, and a clip 15 disposed on the rack 5 and connected to the telescopic end of the electric telescopic assembly 14. The clip 15 extends out of the rack 5 toward one end of the other rack 5. The other rack 5 is provided with a slot that cooperates with the clip 15, which is used to connect the two racks 5 together so that the two racks 5 can move simultaneously and drive the gear 11 to rotate. The combination of the two racks 5 can drive the gear 11 to rotate stably, with a large meshing area. The electric telescopic assembly 14 pushes the clip 15 to move, allowing the two racks 5 to move upward together, thereby driving the gear 11 to rotate.

[0043] In summary, by pulling the pull plate 7, the two mounting plates 4 are driven to approach each other, and the mounting plate 4 drives the threaded sleeve 82 to move, so that the clamping assembly 9 rotates as a whole, and the clamping block 93 cooperates to be clamped into the fixed frame 101, and the clamping block 93 moves downward to press down the bottom plate 104, so that the bottom plate 104 drives the ratchet 102 to rotate, so that the limiting plate 105 rotates synchronously, and the limiting plate 105 stably presses the upper end of the clamping block 93, avoiding the rotation and resetting of the clamping assembly 9, thereby achieving stable limiting of the two mounting plates 4, and sealing the opening by the two mounting plates 4 and the sealing plate 6, so as to avoid the bolt 31 being exposed to the air and corroded, which causes the shutter installation to be unstable and fall off.

[0044] The movable connection between the connecting sleeve 132 and the fixed shaft 12 can realize the connection between two adjacent gears 11. Even if the gear 11 is corroded and cannot be engaged for transmission, transmission can still be performed. As long as one gear 11 can be engaged, stable transmission can be guaranteed, reducing the probability of the sea breeze monsoon climate affecting the device.

[0045] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
