[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figure 2 to Figure 4 , which is the first embodiment of the utility model, provides a boiler decoking tool for a thermal power plant. The boiler decoking tool for a thermal power plant includes an expansion component 200, a limit component 300 and a main body component 100. The three can cooperate to effectively block the dust in the boiler and reduce the risk of dust being inhaled into the lungs of the user.

[0028] The expansion assembly 200 includes an expansion rod 201a, a moving rod 201b, a push rod 201c and a moving block 201d. The moving rod 201b is fixed to one side of the expansion rod 201a, the push rod 201c is hinged to one end of the moving rod 201b, and the moving block 201d is hinged to one end of the push rod 201c.

[0029] There are four expansion rods 201a, and nylon cloth can be installed on the top of the expansion rod 201a. When the four expansion rods 201a are expanded, the nylon cloth can be expanded. When decoking in the boiler, dust can be effectively blocked to prevent the user from inhaling a large amount of dust. There are four moving rods 201b, all of which are fixed on one side of the expansion rod 201a. There are four push rods 201c, all of which are hinged to one end of the moving rod 201b. There are four moving blocks 201d, all of which are hinged to one end of the push rod 201c. The movement of the moving block 201d can drive the push rod 201c to move, so that the push rod 201c squeezes the moving rod 201b to make it move, and the movement of the moving rod 201b can drive the expansion rod 201a to expand.

[0030] The limit assembly 300 is arranged at the bottom of the moving block 201d, and includes a limit block 301a, a movable bar 301b, a moving plate 301c and a support shaft 301d. The limit block 301a is located at the bottom of the moving block 201d, the movable bar 301b is fixed to one side of the limit block 301a, the moving plate 301c is hinged to one end of the movable bar 301b, and the support shaft 301d is movably connected to one side of the moving plate 301c through a rotating shaft.

[0031] A limiting groove corresponding to the limiting block 301a is provided on one side of the positioning column 202b. After the expansion rod 201a is moved to the specified position, the limiting block 301a is engaged with the limiting groove, so that the moving block 201d can be limited to prevent the moving block 201d from moving on its own. When it is necessary to release the limitation of the moving block 201d, the moving plate 301c is moved. The movement of the moving plate 301c can drive the movable bar 301b to move. The movement of the movable bar 301b drives the limiting block 301a to separate from the limiting groove, thereby releasing the limitation of the moving block 201d. The support shaft 301d is used to support the moving plate 301c to prevent the moving plate 301c from deviating when moving.

[0032] Example 2

[0033] Reference Figure 2 to Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0034] Specifically, a support block 202a is provided at one end of the moving rod 201b, the support block 202a is hinged to one end of the moving rod 201b, and a positioning column 202b is fixed to one side of the support block 202a.

[0035] There are four support blocks 202a, which are respectively hinged to one end of the moving rod 201b. The support blocks 202a can support the moving rod 201b to prevent the moving rod 201b from shifting when moving. The positioning column 202b is used to support the support block 202a to prevent the support block 202a from shifting.

[0036] Specifically, a support plate 202c is sleeved on the outer side of the positioning column 202b, and a spring 202d is fixed to the bottom of the support plate 202c.

[0037] When the moving block 201d is moved to expand the expansion rod 201a, the spring 202d will be squeezed, so that the spring 202d applies a squeezing force. When the expansion rod 201a needs to be contracted, the rebound force of the spring 202d can drive the moving block 201d to return to its original position, thereby contracting the expansion rod 201a. The support plate 202c is used to support the spring 202d to prevent the spring 202d from deflecting.

[0038] Specifically, a movable disk 202e is fixed at the bottom of the spring 202d. The movable disk 202e is sleeved on the outside of the positioning column 202b. The movable disk 202e and the positioning column 202b are movably connected.

[0039] When the movable disk 202e is moved, a compressive force can be applied to the spring 202d.

[0040] Specifically, the moving block 201d is fixed to one side of the movable disk 202e.

[0041] The movable plate 202e is moved to drive the movable block 201d to move, and the movement of the movable block 201d can cause the expansion rod 201a to expand.

[0042] Specifically, a torsion spring 302a is sleeved on the outer side of the support shaft 301d, one end of the torsion spring 302a is fixed to one side of the moving plate 301c, and the other end is fixed to one side of the movable disk 202e.

[0043] When the movable plate 301c is moved, a torsional force can be applied to the torsion spring 302a. The movement of the movable plate 301c can drive the movable bar 301b to move. The movement of the movable bar 301b drives the limit block 301a to separate from the limit groove, thereby releasing the limit on the movable block 201d. Then the movable plate 301c is released, and the rotation force of the torsion spring 302a can drive the movable plate 301c to return to its original position so that the limit block 301a is engaged with the limit groove.

[0044] Specifically, a pressing plate 302b is fixed to one side of the movable plate 301c.

[0045] The arrangement of the pressing plate 302b facilitates the user to move the movable plate 301c. The user can move the movable plate 301c by pressing the pressing plate 302b.

[0046] Example 3

[0047] Reference Figure 1 to Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0048] Specifically, a protective shell 302c is provided on the outer side of the movable bar 301b, the movable bar 301b and the protective shell 302c are movably connected, and the protective shell 302c is fixed to the bottom of the movable plate 202e.

[0049] The protective shell 302c is used to protect the moving plate 301c to prevent the moving plate 301c from being damaged by external debris.

[0050] Specifically, it also includes a main body component 100, which is arranged on the positioning column 202b, including a pneumatic pick 101, an extension rod 102 and a handle 103. The extension rod 102 is fixed to one end of the positioning column 202b, the pneumatic pick 101 is fixed to one end of the extension rod 102, and the handle 103 is fixed to the other end of the positioning column 202b.

[0051] The operator holds the handle 103 and places the extension rod 102 in the boiler. At this time, the pneumatic pick 101 will enter the boiler, and then the pneumatic pick 101 uses the energy of compressed air to drive the piston to reciprocate, driving the pick to impact the coke block to break it off. The pneumatic pick 101 belongs to the existing technology, so it will not be elaborated in detail.

[0052] Specifically, an anti-slip cover 104 is provided on the outer side of the handle 103 .

[0053] During the decoking operation, the operator needs to hold the handle 103 firmly to control the position and movement of the pneumatic pick 101. The anti-slip sleeve 104 can increase the friction between the hand and the handle 103 to prevent the hand from slipping due to sweating or oil stains, etc., ensuring that the operator can hold the handle 103 stably and accurately operate the pneumatic pick 101 to perform decoking work.

[0054] During use, when it is necessary to decoke the boiler of a thermal power plant, the operator holds the handle 103 and places the extension rod 102 in the boiler. At this time, the pneumatic pick 101 will enter the boiler, and then the expansion rod 201a needs to be expanded for protection. By pressing the pressure plate 302b, the pressure plate 302b drives the movable plate 301c to move. When the movable plate 301c is moved, a torsional force can be applied to the torsion spring 302a. The movement of the movable plate 301c can drive the movable bar 301b to move. The movement of the movable bar 301b drives the limit block 301a to separate from the limit groove, thereby releasing the limit on the movable block 201d.

[0055] Then the movable disk 202e can be moved, and the movable block 201d can be driven to move by moving the movable disk 202e. When the movable disk 202e moves, it can squeeze the spring 202d, so that the spring 202d applies a squeezing force. The movement of the movable block 201d can drive the push rod 201c to move, so that the push rod 201c squeezes the moving rod 201b to move it. The movement of the moving rod 201b can drive the expansion rod 201a to expand. Nylon cloth can be installed on the top of the expansion rod 201a. When the four expansion rods are After 201a is expanded, the nylon cloth can be expanded, and then the pressure plate 302b is released. The rotating force of the torsion spring 302a can drive the movable plate 301c to return to its original position so that the limit block 301a is engaged with the limit groove, which can prevent the rebound force of the spring 202d from driving the movable block 201d to return to its original position. Then, the pneumatic pick 101 can use the energy of compressed air to drive the piston to reciprocate, drive the pick to impact the coke block, and break it off. At this time, the dust in the boiler will be blocked by the expanded nylon cloth to prevent the user from inhaling a large amount of dust.

[0056] After use, the pressure plate 302b is pressed again to release the limit of the movable disk 202e, and then the rebound force of the spring 202d can drive the moving block 201d to return to its original position, so that the expansion rod 201a can be retracted for the next use.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
