[0024] Reference Figures 1-5A graphite tower with a convenient tower section connection and fastening structure for easy maintenance and disassembly includes a tower body 1, a tower cover 2, and a fixing frame 3. The tower cover 2 is located above the tower body 1. The fixing frame 3 is installed on the outer wall of the tower body 1 by fasteners. An installation ring 101 is sleeved on the outside of the tower body 1. A movable seat 103 is fixedly installed on the outside of the installation ring 101. A movable plate 105 is hinged on the movable seat 103. An extension block 8 is movably arranged inside the movable plate 105. A spring 106 is fixedly installed between one end of the extension block 8 and the inner wall of the movable plate 105. A reinforcing ring 201 is sleeved on the outside of the tower cover 2. A groove block 104 is fixedly arranged on the outside of the reinforcing ring 201. The end of the extension block 8 away from the movable plate 105 is embedded in the interior of the groove block 104. A slider 301 is movably arranged on the fixing frame 3. A threaded collar 803 is fixedly installed on the upper end of the groove block 104. A stud 802 is movably arranged inside the threaded collar 803.

[0025] During use, to enhance the tightness of the tower section installation, after the tower cover 2 and the tower body 1 are precisely aligned, the operator pulls the movable plate 105 upwards, bringing it closer to the tower cover 2. Under the elasticity of the spring 106, the extension block 8 is pushed out of the movable plate 105. The locking block 202 then provides a limiting function for the extension block 8, preventing it from completely separating from the movable plate 105. This allows the other end of the extension block 8 to be inserted into the recessed block 104. The operator then manually twists the stud 802 again. With the cooperation of the threaded collar 803, the stud 802 rotates downwards and extends into the recessed block 104, simultaneously driving the positioning... The column 801 points downward and is inserted into the extension block 8, which strengthens the connection between the extension block 8 and the groove block 104 and prevents loosening. This allows the tower cover 2 to be installed and fixed on the tower body 1. A sealing gasket 203 and an inner connecting ring 102 are installed inside the tower cover 2 and the tower body 1, respectively. The sealing gasket 203 and the inner connecting ring 102 are fitted together to strengthen the sealing of the internal connection. A reinforcing ring 201 and an installation ring 101 are fitted together on the outside of the tower cover 2 and the tower body 1. The reinforcing ring 201 and the installation ring 101 are connected together to further strengthen the tightness of the connection between the tower cover 2 and the tower body 1 and improve the sealing effect.

[0026] In this embodiment, a positioning post 801 is provided at the bottom end of the stud 802. The stud 802 is threadedly connected to the threaded collar 803. The bottom end of the stud 802 is connected to the positioning post 801 through a rotating shaft. The positioning post 801 is located inside the groove block 104. The positioning post 801 is embedded in the connecting extension block 8. The upper end of the slider 301 is fixedly installed with a limiting seat 7.

[0027] During use, to facilitate quick disassembly and maintenance, the operator manually twists the stud 802 counterclockwise. The stud 802 moves upward, causing the positioning pin 801 to separate from the extension block 8. This pulls the locking block 202, causing the extension block 8 to disengage from the groove block 104. The movable plate 105 is pushed away from the tower cover 2, loosening the connection between the tower cover 2 and the tower body 1. Finally, the cylinder 4 is activated. The cylinder 4 pushes the slider 301 upward along the fixed frame 3 by extending and retracting. At the same time, 303 causes the tower cover 2 to rise, separating the tower cover 2 from the tower body 1. This assists the operator in lifting the tower cover 2. Finally, the operator uses tools to loosen multiple bolts 5, which can further remove the tower cover 2 from the fixed frame 3, improving the ease of disassembly.

[0028] In this embodiment, the stud 802 penetrates the upper end of the groove block 104, and a locking block 202 is fixedly provided on one side of the extension block 8. The locking block 202 is slidably connected to the movable plate 105. The locking blocks 202 are symmetrically distributed on the extension block 8. An inner connecting ring 102 is fixedly installed on the inner wall of the tower body 1, and a sealing gasket 203 is fixedly provided on the inner wall of the tower cover 2. The sealing gasket 203 is embedded in the inner connecting ring 102.

[0029] When in use, the cylinder 4 is model MDBB32-50Z-M9BW. The sealing gasket 203 and the inner connecting ring 102 are made of rubber. By fitting and connecting the sealing gasket 203 and the inner connecting ring 102, the sealing performance of the internal connection between the tower body 1 and the tower cover 2 is enhanced.

[0030] In this embodiment, a rotating rod 6 is provided inside the limiting seat 7. A motor 302 is provided at one end of the rotating rod 6. The motor 302 is fixedly connected to one end of the rotating rod 6 through an output shaft. The end of the rotating rod 6 away from the motor 302 is connected to the inner wall of the limiting seat 7 through a rotating shaft.

[0031] When in use, the model of motor 302 is HF-KP73B. When it is necessary to inspect the inside of the tower body 1, first lift the tower cover 2 to the top of the fixed frame 3 by the cylinder 4, and then start the motor 302. The motor 302 drives the rotating rod 6 to rotate through the output shaft. The rotating rod 6 drives the connecting frame plate 303 to flip upward, and at the same time drives the tower cover 2 to tilt upward, so as to facilitate the staff to inspect the inside of 1.

[0032] In this embodiment, a connecting frame plate 303 is installed between the fixed frame 3 and the outer wall of the tower cover 2. One end of the connecting frame plate 303 is fixedly connected to the rotating rod 6. A bolt 5 is provided at the end of the connecting frame plate 303 near the tower cover 2, and the end of the connecting frame plate 303 away from the rotating rod 6 is installed on the outer wall of the tower cover 2 by the bolt 5.

[0033] In use, the reinforcing ring 201 and the mounting ring 101 are mainly made of stainless steel. By connecting the reinforcing ring 201 and the mounting ring 101, the tightness of the connection between the tower cover 2 and the tower body 1 is further strengthened.

[0034] In this embodiment, a cylinder 4 is installed inside the fixing frame 3 by fasteners. The top of the cylinder 4 is fixedly connected to the slider 301. The motor 302 is installed on the slider 301 by fasteners. The reinforcing ring 201 is embedded in the connecting mounting ring 101.

[0035] In use, the elasticity of the spring 106 is used to push the extension block 8 into the groove block 104. The locking block 202 provides a limiting function for the extension block 8, preventing the extension block 8 from completely separating from the movable plate 105, while facilitating the pulling of the extension block 8 to separate from the groove block 104.

[0036] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In order to strengthen the tightness of the tower section installation, after the tower cover 2 and the tower body 1 are precisely connected, the worker pulls the movable plate 105 upward, so that the movable plate 105 is close to the tower cover 2. Under the elasticity of the spring 106, the extension block 8 is pushed out of the movable plate 105. Then the locking block 202 provides a limiting function for the extension block 8, preventing the extension block 8 from completely separating from the movable plate 105, so that the other end of the extension block 8 is inserted into the groove block 104. The worker manually twists the stud 802 again. With the cooperation of the threaded collar 803, the stud 802 rotates downward and extends into the groove block 104. At the same time, it drives the positioning pin 801 downward and inserts it into the extension block 8, which strengthens the firmness of the connection between the extension block 8 and the groove block 104 and prevents loosening. Thus, the tower cover 2 is installed and fixed on the tower body 1. A sealing gasket 203 and an inner connecting ring 102 are respectively installed inside the tower cover 2 and the tower body 1. 203 engages with the inner connecting ring 102 to enhance the sealing of the internal connection. A reinforcing ring 201 and an installation ring 101 are fitted onto the outside of the tower cover 2 and the tower body 1. The engagement of the reinforcing ring 201 and the installation ring 101 further strengthens the tightness of the connection between the tower cover 2 and the tower body 1, improving the sealing effect. For easy disassembly and maintenance, workers manually turn the stud 802 counterclockwise. The stud 802 moves upward, causing the positioning pin 801 to separate from the extension block 8, thus pulling the locking block 202. This causes the extension block 8 to disengage from the groove block 104, pushing the movable plate 105 away from the tower cover 2, loosening the connection between the tower cover 2 and the tower body 1. Finally, the cylinder 4 is activated, and the cylinder 4 pushes the slider 301 upward along the fixed frame 3 by extending and retracting. At the same time, 303 drives the tower cover 2 to rise, separating the tower cover 2 from the tower body 1. This assists the staff in lifting the tower cover 2. Finally, the staff uses tools to loosen multiple bolts 5, which can further disassemble and remove the tower cover 2 from the fixed frame 3, improving the ease of disassembly.
