[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] 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.

[0029] 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.

[0030] Example 1

[0031] Reference Figures 1 to 6 , which is the first embodiment of the utility model, and this embodiment provides an emergency mechanism, which includes a feeding component 100, including a feeding pipe 101, a valve 102 is fixedly connected to the inside of the feeding pipe 101, the valve 102 includes a ball valve 102a located inside the feeding pipe 101, an auxiliary component 200, located on one side of the feeding component 100, the auxiliary component 200 includes an auxiliary switch 201, an alarm component 202 is fixedly connected to one side of the auxiliary switch 201, and a conversion component 203 is installed on one side of the auxiliary switch 201.

[0032] Specifically, a first rotating column 102b is fixedly connected to one side of the ball valve 102a, a second rotating column 102c is fixedly connected to the other side of the ball valve 102a, a first telescopic rod 102d is fixedly connected to one side of the first rotating column 102b, and one end of the first telescopic rod 102d is rotatably connected to the cylinder 102e through a connecting column.

[0033] When in use, the first rotating column 102b and the second rotating column 102c support the ball valve 102a. When the ball valve 102a rotates, the first rotating column 102b and the second rotating column 102c rotate together with the ball valve 102a. The first rotating column 102b is connected to the cylinder 102e through the connecting column. When the cylinder 102e is pushed and pulled, it can drive the first rotating column 102b to rotate, and then drive the ball valve 102a to rotate.

[0034] It should be noted that the auxiliary switch 201 includes an auxiliary rod 201a fixedly connected to the second rotating column 102c, one end of the auxiliary rod 201a is fixedly connected to a telescopic box 201b via a connecting column, and a shell 201c is fixedly connected to the side wall of the telescopic box 201b.

[0035] When in use, the shell 201c is fixedly connected to one side of the discharge pipe 101, and the part of the telescopic box 201b fixedly connected to the shell 201c always remains stationary. When the telescopic box 201b contains coal ash, the movable part of the telescopic box 201b is pushed to move due to gravity, pushing the auxiliary rod 201a at the bottom of the telescopic box 201b to rotate.

[0036] When in use, the telescopic box 201b is composed of two sections, the upper section of the telescopic box 201b is larger than the lower section, and the lower section of the telescopic box 201b can slide inside the upper section.

[0037] Furthermore, a first sleeve 201d is fixedly connected to the bottom of the telescopic box 201b, a first connecting tube 201e is slidably connected to the inside of the first sleeve 201d via a sliding plate, a first supporting base 201f is fixedly connected to the bottom of the first connecting tube 201e, the first connecting tube 201e is L-shaped, one end of the first connecting tube 201e is fixedly connected to the second telescopic rod 201g, and one end of the second telescopic rod 201g is rotatably connected to the auxiliary rod 201a via a connecting column.

[0038] When in use, a cavity is formed in the middle of the first connecting tube 201e and the first sleeve 201d, and the first connecting tube 201e and the first sleeve 201d are interconnected. The first connecting tube 201e can slide inside the first sleeve 201d through a sliding plate. When the first connecting tube 201e slides inside the first sleeve 201d, the internal space of the first sleeve 201d is squeezed, that is, the air in the first sleeve 201d, the first connecting tube 201e and the second telescopic rod 201g is squeezed, thereby pushing the second telescopic rod 201g to extend, that is, pushing the other side of the auxiliary rod 201a to rotate, and working together with the telescopic box 201b to rotate the auxiliary rod 201a.

[0039] The bottom of the telescopic box 201b is fixedly connected to the second sleeve 202a, and the bottom of the second sleeve 202a is slidably connected to the second connecting tube 202b through a sliding plate. The second connecting tube 202b is L-shaped, and one end of the second connecting tube 202b passes through the shell 201c.

[0040] Preferably, when the telescopic box 201b is extended due to the gravity of the coal ash, the second sleeve 202a is pushed to move in the same manner as the first sleeve 201d. The connection relationship and movement relationship between the second connecting tube 202b and the second sleeve 202a are the same as those between the first connecting tube 201e and the first sleeve 201d. Therefore, when the second connecting tube 202b moves in the second sleeve 202a, the space of the second sleeve 202a is squeezed. During this process, the position of the second connecting tube 202b remains stationary and the second sleeve 202a moves.

[0041] Among them, one end of the second connecting tube 202b is fixedly connected to a one-way valve, the interior of the second connecting tube 202b is fixedly connected to a vibration plate 202c, and one side of the second connecting tube 202b is fixedly connected to a second support 203f.

[0042] When in use, the second connecting tube 202b extends out of the shell 201c. When the air inside the second connecting tube 202b is compressed, the air is blown out from the one-way valve at one end of the second connecting tube 202b. During this process, the vibration plate 202c in the second connecting tube 202b vibrates, vibrates the air, and makes a sound, which is the same as the pronunciation method of a flute, a horn, etc. The second support 203f supports the second connecting tube 202b.

[0043] Example 2

[0044] Reference Figures 1 to 9 , which is the second embodiment of the utility model, comprises a telescopic box 201b, the top of which is fixedly connected with a cover 203a, and the cover 203a is composed of a telescopic plate.

[0045] Specifically, one end of the cover 203a is fixedly connected to a connecting rod 203b, one end of the connecting rod 203b is fixedly connected to a gear 203c, the gear 203c is rotatably connected to the inside of the discharge pipe 101, the gear 203c is meshed with a rack 203d, one end of the rack 203d is fixedly connected to a telescopic column 203e, one end of the telescopic column 203e is U-shaped, and one end of the telescopic column 203e is fixedly connected to the discharge pipe 101.

[0046] Furthermore, when the connecting rod 203b rotates with the gear 203c, the cover 203a can be driven to shrink. The shrinkage of the cover 203a allows the coal ash above the telescopic box 201b to enter the telescopic box 201b. When the rack 203c moves, the gear 203c can be driven to rotate, thereby forming a gap between the cover 203a and the telescopic box 201b. When the telescopic column 203e is compressed, the rack 203d is driven to move. The telescopic column 203e has a certain supporting force. A certain pressure needs to be reached to press the telescopic column 203e to shrink. At the same time, the U-shaped setting at one end of the telescopic column 203e can facilitate the rotation of the second rotating column 102c.

[0047] In summary, when a problem occurs in the cylinder 102e, resulting in insufficient power to push the ball valve 102a to rotate, coal ash accumulates on the ball valve 102a, squeezing the ball valve 102a. At this time, the second rotating column 102c moves downward with the ball valve 102a, pressing the telescopic column 203e to shrink, and at the same time drives the rack 203d to move, driving the gear 203c to rotate, the rack 203d is meshed with the gear 203c, the rack 203d and the gear 203c are helical teeth, and the rotation of the gear 203c drives the connecting rod 203b connected to the gear 203c to rotate, and at the same time drives the cover 203a to shrink, and a gap is formed between the cover 203a and the telescopic box 201b, and the coal ash can enter the telescopic box 201b from the gap. The telescopic box 201b extends under the action of the coal ash gravity, pressing the auxiliary rod 201a, and at the same time the telescopic box 201b drives the first sleeve 201d and the second sleeve 202a move, and the movement of the first sleeve 201d and the second sleeve 202a squeezes the air in the cylinder, and the compressed air in the first sleeve 201d pushes the second telescopic rod 201g to extend through the first connecting tube 201e, pushing the other end of the auxiliary rod 201a, that is, one end of the auxiliary rod 201a is squeezed by the telescopic box 201b, and the other end of the auxiliary rod 201a is pushed by the second telescopic rod 201g. There are two forces on the rotation of the auxiliary rod 201a, which makes the auxiliary rod 201a rotate, and works together with the cylinder 102e to make the ball valve 102a rotate, and at the same time, the compressed air in the second connecting tube 202b at one end of the second sleeve 202a is blown out from the one-way valve at one end of the second connecting tube 202b, driving the vibration plate 202c to vibrate, and making a sound to remind the staff that there is a problem with the cylinder 102e.

[0048] Example 3

[0049] Reference Figures 1 to 9, which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a main body component 300, which is located on one side of the unloading component 100. The main body component 300 includes a blast furnace 301. The ash in the blast furnace 301 enters the clean gas pipeline 306 through the semi-clean gas pipeline 302 and the gas purification unit 304. The semi-clean gas pipeline 302 is fixedly connected with a raw gas cut-off valve 303, and the clean gas pipeline 306 is fixedly connected with a clean gas cut-off valve 305. The stored ash in the gas purification unit 304 enters the ash conveying closed channel 308 through the unloading pipeline 101 to the centralized ash bin 309a for external transportation. One end of the ash conveying closed channel 308 is fixedly connected There is a gas supply source 309, a temperature sensor 1 309b and a temperature sensor 2 309c are installed on one side of the discharge pipeline 101, a leak detection pressure pipeline 309d is installed on the other side of the discharge pipeline 101, an electric stop valve 1 309e and an electric stop valve 2 309f are installed on one side of the leak detection pressure pipeline 309d, a gas supply source 2 309f-1 is installed on one side of the electric stop valve 2 309f, an electric stop valve 3 309g is installed on one side of the electric stop valve 1 309e, a filter 309g-1 is installed on one side of the electric stop valve 309g, and a pressure sensor 309g-2 and a gas alarm 309g-3 are installed on one side of the filter 309g-1.

[0050] When in use, after the ash discharge valve is closed after the ash discharge is completed

[0051] 1) Start to execute the temperature-time difference calculation method, and include the collected temperature sensor 1 309b as T1 and the temperature sensor 2 309c as T2 into the background program calculation, and form different temperature-time curve differences within N seconds: W1, W2, W3...Wn, providing an alarm interlocking function;

[0052] 2) Open the electric stop valve 1 309e and the electric stop valve 2 309f to detect leaks and clear the pressure pipeline 309d, and close it after N1 seconds; open the electric stop valve 1 309e and the electric stop valve 3 309g after N2 seconds. At this time, the pressure sensor 309g-2 and the gas alarm 309g-3 collect data to calculate the pressure-time difference, and form different pressure-time curve differences within N3 seconds: P1, P2, P3.....Pn, which are used to judge the alarm interlock.

[0053] ① When the temperature-time difference calculation method shows: T1 ≥ T2, T2 has an upward trend, Wn-W(n-1)>0, it can be preliminarily judged that the ash discharge valve is expected to leak;

[0054] ② When the pressure difference calculation method shows that: P continues to rise, Pn-P(n-1)>0, and the value of the gas alarm also rises to a stable level.

[0055] ③ Combining the above two points, the program automatically closes the raw gas shut-off valve 303 and the clean gas shut-off valve 305 after the alarm, opens the raw gas shut-off valve 303, and when the pressure sensor 309g-2 reaches Gpa, closes the raw gas shut-off valve 303, and then performs ash unloading and action.

[0056] ④ When the gas purification unit is used for residual pressure cleaning and put into operation, phenomena ① and ② occur. At this time, an alarm is issued to remind the operator to conduct on-site inspection and replacement, and a report is generated and transmitted to relevant departments.
