The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they mutually exclusive with other embodiments, either alone or in the alternative.

[0026] Example 1 1 to 4, which is a first embodiment of the present invention, provides an attachment mechanism, which includes a body member 100 including a filter assembly 101, a functional assembly 102 disposed in the filter assembly 101, a driving assembly 103 disposed in the filter assembly 101, and a clamping assembly 104 disposed in the functional assembly 102, and a power member 200 including a conversion assembly 201 disposed in the functional assembly 102, and a transmission assembly 202 connected to the conversion assembly 201, and the filter assembly 101 filters the gas discharged from the exhaust pipe to prevent dust and particulate matter in the gas from being discharged into the atmosphere. When the exhaust pipe is inserted into the filter assembly 101, the conversion assembly 201 is pushed to move into the functional assembly 102, and the translational force can be converted into a rotational force. The transmission assembly 202 then drives the drive assembly 103 to rotate while contacting the clamping assembly 104 and moving relatively to clamp the exhaust pipe.

The filter tube 101a can communicate with the inside of the filter tube 101a. A slide groove 102c is provided at the end of the filter tube 101a that is away from the filter nozzle 101b. A matching groove 102d is provided at both ends of the inner wall of the device groove 101c in the filter tube 101a. The filter tube 101a and the filter nozzle 101b are fitted together to filter the gas discharged from the exhaust pipe and prevent dust and particulate matter in the gas from being discharged into the atmosphere. The inside of the device groove 101c is used to position the transmission assembly 202. The spiral groove 102a and the position limiting groove 102b jointly position the conversion assembly 201 and can also guide the conversion assembly 201, so that the conversion assembly 201 can rotate during movement. The role of the matching groove 102d is to position the transmission assembly 202 and allow the transmission assembly 202 to rotate in the device groove 101c.

[0028] Further, the driving assembly 103 includes a driving ring 103a provided in the filtration tube 101a, an abutment groove 103b opened on the outside of the driving ring 103a, and an output rod 103c provided in the abutment groove 103b. The clamping assembly 104 includes an L-shaped connecting rod 104a provided at an end of the output rod 103c, a fixing clamp 104b provided at an end of the L-shaped connecting rod 104a, and a locking groove 104c opened at an end of the fixing clamp 104b. The driving ring 103a is rotatably connected to a portion adjacent to the slide grooves 102c of the filtration tube 101a. The abutment grooves 103b are both opened at the portions of the driving ring 103a located in the pair of slide grooves 102c. The pair of abutment grooves 103b are formed in an arc shape. The pair of abutment grooves 103b are provided with output rods 103c in both of the pair of abutment grooves 103b. An L-shaped connecting rod 104a is fixedly connected to the end of each of the driving rings 103a and 103b, and the pair of L-shaped connecting rods 104a are both slidably connected in a pair of slide grooves 102c.

An engagement groove 104c is formed at the end of the upper fixed clamp 104b. The role of the output rod 103c is to combine the power between the L-shaped connecting rod 104a and the driving ring 103a. The driving ring 103a abuts against the output rod 103c during rotation, lowering the upper L-shaped connecting rod 104a and raising the lower L-shaped connecting rod 104a, so that the fixed clamps 104b move relatively to clamp and fix the exhaust piping.

[0029] The operation process is as follows: first, align the end of the filter tube 101a with the exhaust pipe, then push the exhaust pipe into the filter tube 101a, and at this time, rotate the driving ring 103a to move the abutment groove 103b and abut against the output rod 103c, and due to the position limit of the slide groove 102c, the output rod 103c in the upper and lower slide grooves 102c moves relative to the L-shaped connecting rod 104a, and the fixed clamp 104b moves relatively to clamp the exhaust pipe, and then the fixed clamp 104b is locked, thereby achieving the purpose of easily attaching the filter tube 101a to the exhaust pipe.

[0030] Example 2 1 to 5, which is a second embodiment of the present invention, different from the previous embodiment, the conversion assembly 201 includes an output block 201a arranged in the position limiting groove 102b, a shielding bar 201b arranged outside the output block 201a, a rotating ring 201c arranged at the end of the output block 201a, and a lever 201d arranged outside the rotating ring 201c, where the lever 201d can move in the spiral groove 102a, the output block 201a is slidably connected in the position limiting groove 102b, the shielding bar 201b is fixedly connected to the part of the output block 201a located in the position limiting groove 102b, and the device groove of the output block 201a. A rotating ring 201c is rotatably connected to the end located at 101c, and a lever 201d is fixedly connected to the outside of the rotating ring 201c. The lever 201d is movably connected within the spiral groove 102a. The output block 201a can transmit an abutting force to the rotating ring 201c, and the rotating ring 201c can drive the lever 201d to move within the spiral groove 102a during movement, thereby causing the rotating ring 201c to rotate along the trajectory of the spiral groove 102a. The shielding bar 201b shields the position limiting groove 102b, thereby preventing dust and particulate matter in the gas from entering the position limiting groove 102b.

[0031] Further, the transmission assembly 202 includes a limiting rod 202a provided in the rotating ring 201c, and a functional spring 202b fitted on the outside of the limiting rod 202a and located between the rotating ring 201c and the inner wall of the device groove 101c, where the limiting rod 202a is movably connected in the matching groove 102d and connected to the driving ring 103a, the multiple limiting rods 202a are movably connected inside the matching groove 102d, and the rotating ring 201c is slidably connected to the outside of the multiple limiting rods 202a. The driving ring 103a is fixedly connected to the outside of the limiting ring, and a functional spring 202b is fitted between the rotating ring 201c and the inner wall of the device groove 101c on the outside of the rod bodies of the multiple limiting rods 202a, and the limiting rods 202a play the role of transmitting the acting force of the rotating ring 201c to the driving ring 103a, and the functional spring 202b can push the output block 201a and the rotating ring 201c to reset when the external abutment against the output block 201a is lost.

[0032] The remaining structure is the same as in the first embodiment.

[0033] The operation process is as follows: When the above-mentioned filter tube 101a is inserted outside the exhaust pipe, the exhaust pipe abuts against the output block 201a, at this time, the output block 201a drives the rotating ring 201c to move toward the filter nozzle 101b, during the movement, the rotating ring 201c drives the lever 201d to move within the spiral groove 102a, and the output block 201a is restricted by the position restriction groove 102b, so that the rotating ring 201c and the lever 201d rotate along the trajectory of the spiral groove 102a, thereby realizing the conversion of the acting force, during the rotation, the limiting rod 202a is also driven to rotate within the matching groove 102d, and when the limiting rod 202a rotates, the driving ring 103 a is driven to rotate, thereby achieving the purpose of providing power to the driving ring 103a, and by driving the shielding bar 201b to further shield the position limiting groove 102b while the output block 201a is moving, it is possible to prevent dust and particulate matter in the gas from entering the position limiting groove 102b. During the movement of the rotating ring 201c, the rotating ring 201c further presses the functional spring 202b, so that when the external abutment force on the output block 201a is lost, the compressed functional spring 202b rebounds and pushes the rotating ring 201c and the output block 201a to reset, thereby achieving the purpose of resetting the internal structure.

[0034] Example 3 1 to 8, which is a third embodiment of the present invention, different from the previous embodiment, this embodiment provides a filtering device for exhaust pipe of thermal power plant. The filtering device for exhaust pipe of thermal power plant has the above-mentioned mounting mechanism, and further includes a locking member 300 including a limiting assembly 301 provided in the clamping assembly 104 and an abutting assembly 302 connected to the clamping assembly 104. When the clamping assembly 104 moves relatively, the abutting assembly 302 abuts against the limiting assembly 301, and when the clamping assembly 104 merges, the abutting assembly 302 and the limiting assembly 301 are locked together. In this case, the abutting assembly 302 can be disengaged by moving the abutting assembly 302, thereby realizing the locking and unlocking of the clamping assembly 104.

[0035] Furthermore, the limiting assembly 301 includes a shaft lever 301a provided in the locking groove 104c, a connecting rod 301b provided outside the shaft lever 301a, a tilting block 301c provided at the end of the connecting rod 301b, and a coil spring 301d fitted to the outside of the shaft lever 301a. The abutment assembly 302 includes an L-shaped abutment rod 302a provided at the end of the fixed clamp 104b, a moving groove 302b opened outside the L-shaped abutment rod 302a, a square-shaped frame 302c provided in the moving groove 302b, and a square-shaped frame 302c. The shaft lever 301a is rotatably connected within the locking groove 104c, a connecting rod 301b is fixedly connected to the outside of the rod body of the shaft lever 301a, an inclined block 301c is fixedly connected to an end of the connecting rod 301b, a coil spring 301d is fitted to the outside of the shaft lever 301a, and a coil spring 301d is fitted to the end of the lower fixed clamp 104b corresponding to the inclined block 301c. At this position, an L-shaped abutment rod 302a is fixedly connected, and the end inclined surface of the L-shaped abutment rod 302a coincides with the inclined block 301c. A moving groove 302b is opened on the outer side of the rod body of the L-shaped abutment rod 302a. A square-shaped frame 302c is slidably connected inside the moving groove 302b. A push rod 302d is fixedly connected to the inner wall of the square-shaped frame 302c located inside the moving groove 302b. The push rod 302d can pass through the moving groove 302b. A return spring 304 is provided on the outer side of the push rod 302d. 2e is fitted into the return spring 302e, and both ends of the return spring 302e are connected to the movable groove 302b and the inner wall of the L-shaped frame 302c, respectively, the shaft lever 301a can play the role of supporting the connecting rod 301b and the inclined block 301c, and when the inclined block 301c and the L-shaped abutment rod 302a are coupled, the pair of fixed clamps 104b can be engaged, and the L-shaped frame 302c and the push rod 302d are arranged to abut against the connecting rod 301b to release the engagement between the inclined block 301c and the L-shaped abutment rod 302a.

[0036] The remaining structure is the same as in Example 1 or 2.

[0037] The operation process is as follows: When the two pairs of fixed clamps 104b move relative to each other, the L-shaped contact rod 302a comes into contact with the tilt block 301c first, and then comes into contact with the tilt block 301c through the inclined surface, and rotates around the shaft lever 301a as the center of rotation. During the rotation of the shaft lever 301a, the coil spring 301d is unwound. After the inclined surface of the L-shaped contact rod 302a rises to a certain degree, the L-shaped contact rod 302a no longer comes into contact with the tilt block 301c. At this time, the unwound coil spring 301d drives the shaft lever 301a to reset, and also resets the connecting rod 301b and the tilt block 301c. At this time, the L-shaped contact rod 302a and the tilt block 301c interfere with each other. When it is desired to release the lock, the L-shaped frame 302c is moved outward. When the L-shaped frame 302c is pulled in the direction of the arrow, during the movement, the L-shaped frame 302c drives the push rod 302d to move outward and abuts against the connecting rod 301b, so that the connecting rod 301b and the inclined block 301c rotate around the shaft lever 301a as the center of rotation. At this time, the inclined block 301c and the L-shaped abutment rod 302a do not interfere with each other. Furthermore, under the action of the functional spring 202b, the fixed clamp 104b is reset, thereby realizing the locking and unlocking of the fixed clamp 104b. In addition, when the return spring 302e is pressed during the movement of the L-shaped frame 302c, when the external pulling force is lost, the return spring 302e rebounds and drives the L-shaped frame 302c and the push rod 302d to reset.
