When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0040] Example 1, reference Figure 1 to Figure 4, which is the first embodiment of the present invention, and which provides a fire prevention device for a control cabinet of a gas turbine static frequency converter, comprising: a control component 100 including a control cabinet body 101, heat dissipation windows 102 arranged on both sides of the control cabinet body 101, and a heat dissipation plate 103 arranged on the heat dissipation windows 102; and;

[0041] The heat dissipation windows 102 are located on both sides of the control cabinet body 101 , and the heat dissipation plates 103 are located on the heat dissipation windows 102 for dissipating heat for the control cabinet body 101 .

[0042] The blocking component 200 includes a blocking plate 201 disposed on the heat dissipation window 102, a sliding component 202 disposed on the blocking plate 201, a starting component 203 disposed on the sliding component 202, and a sealing component 204 disposed on the sliding component 202; and,

[0043] Among them, the sealing plate 201 is located at the upper end of the heat dissipation window 102, and the sealing plate 201 is adapted to the heat dissipation window 102 to seal the heat dissipation window 102. The sliding component 202 is located between the heat dissipation window 102 and the sealing plate 201, and is used to prepare for the sealing plate 201 to block the heat dissipation window 102. The starting component 203 is located on the sliding component 202, and is used to sense the problems inside the control cabinet body 101 in real time, and start the sliding component 202 according to the temperature change, thereby facilitating the sealing work of the sealing plate 201.

[0044] The sliding assembly 202 includes a sliding carriage 202a arranged on the heat dissipation window 102, and a sliding plate 202b arranged on the sealing plate 201; the sliding plate 202b and the sliding carriage 202a are slidably connected, the sliding plate 202b and the sealing plate 201 are fixedly connected, and the sealing plate 201 is adapted to the heat dissipation plate 103.

[0045] Among them, the cross-section of the sliding slide 202a is U-shaped, and the sliding slide 202a is arranged on one side of the heat dissipation window 102. The sliding slide 202a is fixedly connected to the control cabinet body 101. The sliding slide 202a is used to provide a sliding path for the blocking plate 201, so that the blocking plate 201 slides along the path on the sliding slide 202a, thereby facilitating the blocking plate 201 to achieve the blocking work. The sliding slide plate 202b is located on both sides of the blocking plate 201, which is adapted to the sliding slide 202a, thereby enabling the blocking plate 201 to slide under guidance.

[0046] The sealing assembly 204 includes a sealing air cushion 204a disposed on the inner wall of the sliding carriage 202a, and an extrusion air bag 204b disposed on the sliding carriage 202a; the extrusion air bag 204b is in conflict with the bottom of the blocking plate 201, and the sealing air cushion 204a and the extrusion air bag 204b are interconnected.

[0047] Among them, the sealing air cushion 204a is located on the inner wall of the sliding slide 202a, and cooperates with the extrusion air bag 204b to achieve sealing of the sealing plate 201, thereby facilitating the sealing work of the sealing plate 201. The extrusion air bag 204b is located at the bottom of the groove of the sliding slide 202a, and the extrusion air bag 204b and the sealing air cushion 204a are interconnected. The sealing plate 201 slides on the sliding slide 202a and contacts the extrusion air bag 204b, so that the gas in the extrusion air bag 204b flows into the sealing air cushion 204a along the extrusion flow, so that the sealing air cushion 204a expands and contacts the sealing plate 201, thereby achieving close contact between the sealing plate 201 and the heat dissipation plate 103, thereby improving the sealing effect of the sealing plate 201.

[0048] The starting assembly 203 includes an anti-slip baffle 203a arranged at the upper end of the sliding slide 202a, a supporting pad rod 203b arranged on the anti-slip baffle 203a, and a blocking member 203c arranged on the supporting pad rod 203b; the anti-slip baffle 203a and the sliding slide 202a are rotatably connected, and the supporting pad rod 203b is located below the anti-slip baffle 203a.

[0049] Among them, the anti-slip baffle 203a is located at the upper end of the sliding slide 202a, and the number of the anti-slip baffles 203a is two. The anti-slip baffle 203a is used to increase the contact area between the sliding slide 202a and the blocking plate 201. The support pad 203b is located below the anti-slip baffle 203a. The support pad 203b and the anti-slip baffle 203a are fixedly connected. The cross-section of the support pad 203b is a quarter circle. The support pad 203b and the blocking member 203c cooperate with each other to sense and support the anti-slip baffle 203a.

[0050] The blocking member 203c includes a sliding groove 203c-1 opened on the sliding slide 202a, and a resistance protrusion 203c-2 arranged on the sliding groove 203c-1; the supporting pad 203b and the sliding groove 203c-1 are slidably connected, and the resistance protrusion 203c-2 is located at the end of the sliding groove 203c-1, and the resistance protrusion 203c-2 and the supporting pad 203b are in resistance.

[0051] Among them, the sliding groove 203c-1 is adapted to the supporting pad rod 203b, and the diameter of the sliding groove 203c-1 is larger than that of the supporting pad rod 203b, one end of the resisting protrusion 203c-2 extends into the interior of the sliding groove 203c-1, and the diameter of the other end of the resisting protrusion 203c-2 is larger than that of the end of the resisting protrusion 203c-2 extending into the sliding groove 203c-1, and the material of the resisting protrusion 203c-2 is waxy material and will melt when encountering high temperature. When a fire occurs inside the control cabinet body 101 and the temperature is too high, the resisting protrusion 203c-2 melts, causing the supporting pad rod 203b to squeeze the resisting protrusion 203c-2 and pass through the sliding groove 203c-1 smoothly, thereby allowing the blocking plate 201 to slide on the sliding slide 202a.

[0052] Operation process: Under normal circumstances, the heat sink 103 helps the control cabinet body 101 to dissipate heat, and the sealing plate 201 is in the open position to ensure air circulation. When the temperature inside the control cabinet body 101 rises, the abutment protrusion 203c-2 in the starting component 203 begins to melt. After the abutment protrusion 203c-2 melts, the supporting pad rod 203b is no longer blocked and can slide along the sliding groove 203c-1. The movement of the supporting pad rod 203b causes the sealing plate 201 to start sliding along the sliding slide 202a, and wait until the sealing plate 201 completely covers the heat dissipation window 102 to prevent air from entering the control cabinet body 101. During the sliding process, the sealing plate 201 presses down to squeeze the airbag, and the gas is pushed into the sealing air cushion 204a to make it expand. The expanded sealing air cushion 204a ensures that a tight seal is formed between the sealing plate 201 and the heat sink 103 to prevent the spread of fire.

[0053] Example 2, reference Figure 5 and Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, and the difference is that the vacuum component 300 includes an exhaust fan 301 arranged at the upper end of the control cabinet body 101, a filter component 302 arranged on the exhaust fan 301, and a connecting component 303 arranged on the filter component 302.

[0054] Among them, the exhaust fan 301 is located at the upper end of the control cabinet body 101, and is used to cooperate with the sealing plate 201 for sealing. By starting the exhaust fan 301 through the sealing plate 201, the vacuum state inside the control cabinet body 101 can be quickly achieved, thereby achieving rapid fire extinguishing. In the process of exhausting air by the exhaust fan 301, through the cooperation of the filter component 302, the gas after combustion can be filtered, and the toxic and harmful gases after combustion can be purified and adsorbed so that they can be discharged after meeting the discharge standards.

[0055] Preferably, the connecting component 303 is located between the blocking plate 201, the exhaust fan 301 and the filter component 302, and is used to connect the three components in series so that the three are associated with each other, and the filter component 302 and the exhaust fan 301 are started by sliding the blocking plate 201, thereby realizing the operation of the entire system.

[0056] The filter assembly 302 includes a filter housing 302a disposed below the exhaust fan 301, a filter adsorption plate 302b disposed on the filter housing 302a, a blocking member 302c disposed below the filter adsorption plate 302b, and a locking member 302d disposed on the blocking member 302c; the filter housing 302a is located below the exhaust fan 301, and the filter adsorption plate 302b is located inside the filter housing 302a.

[0057] Specifically, the filter housing 302a and the exhaust fan 301 are fixedly sealed and connected, so that the exhaust fan 301 is conveniently designed to purify the air. The filter adsorption plate 302b is located inside the filter housing 302a. The filter adsorption plate 302b contains a large amount of activated carbon, which can effectively adsorb organic pollutants and some inorganic gases. The blocking member 302c is used to protect and seal the filter adsorption plate 302b when it is not in use to prevent the internal material of the filter adsorption plate 302b from getting damp. The retaining member 302d is used to fix the blocking member 302c, and the blocking member 302d cooperates with the blocking member 302c to realize the operation and protection of the filter adsorption plate 302b.

[0058] The blocking member 302c includes a blocking ring 302c-1 arranged on the filter housing 302a, and a blocking plate 302c-2 arranged on the blocking ring 302c-1; the blocking ring 302c-1 and the blocking plate 302c-2 are rotatably connected; the locking member 302d includes a locking clamp 302d-1 arranged on the blocking ring 302c-1, and a locking groove 302d-2 opened on the blocking ring 302c-1.

[0059] Among them, the blocking ring 302c-1 is located below the filter housing 302a, and the blocking ring 302c-1 and the filter housing 302a are fixedly connected. The blocking ring 302c-1 is used to install the blocking plate 302c-2 and the positioning clamp 302d-1. The number of blocking plates 302c-2 is four, which are arranged in a circular array. The blocking plate 302c-2 and the blocking ring 302c-1 are rotatably connected, and the contact surfaces of the two adjacent blocking plates 302c-2 are provided with sealing strips, so that sealing can be achieved after the blocking plates 302c-2 are merged, so as to protect the filter adsorption plate 302b. The positioning clamp 302d-1 is symmetrically arranged, and the cross-section of the positioning clamp 302d-1 is U-shaped, which is respectively located between two adjacent blocking plates 302c-2. The blocking plate 302c-2 can be opened and closed by sliding the positioning clamp 302d-1 in the positioning groove 302d-2.

[0060] The rest of the structure is the same as that of Example 1.

[0061] Operation process: In the initial state, the blocking plate 201 is in a normal position, the exhaust fan 301 is not started, the blocking plate 302c-2 is in a closed state, and the filter adsorption plate 302b is protected. When a fire occurs, the blocking plate 201 starts to seal the heat dissipation window 102, and the movement of the blocking plate 201 starts the exhaust fan 301 through the connecting component 303. The exhaust fan 301 starts to suck the air inside the control cabinet to create a vacuum environment. The air passes through the filter housing 302a and enters the filter adsorption plate 302b. The activated carbon and other materials in the filter adsorption plate 302b adsorb harmful gases. Under the action of the exhaust fan 301, the purified air is discharged. After the system is operated, the exhaust fan 301 is turned off, the blocking plate 201 is restored to its original position, and the entire system returns to its initial state.

[0062] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the connecting component 303 includes a connecting steel wire 303a arranged on the blocking plate 201, a traction pull block 303b arranged on the connecting steel wire 303a, and a traction pull ring 303c arranged on the clamping clamp 302d-1; the traction pull block 303b is adapted to the traction pull ring 303c.

[0063] Among them, the connecting steel wire 303a is located between the blocking plate 201 and the traction block 303b, and the connecting steel wire 303a is fixedly connected to the blocking plate 201 and the traction block 303b. The cross-section of the traction block 303b is triangular, and the traction block 303b and the traction ring 303c are adapted to each other. The traction ring 303c is pulled by the rising of the traction block 303b, thereby driving the positioning clamp 302d-1 to move, thereby opening the blocking plate 302c-2.

[0064] The connection assembly 303 further includes a second abutting protrusion 303d disposed on the connection wire 303a, and a control switch 303e disposed on the upper end of the control cabinet body 101; the second abutting protrusion 303d abuts against the control switch 303e.

[0065] Specifically, the second contact protrusion 303d is located at one end of the connecting wire 303a close to the traction block 303b, and the second contact protrusion 303d is adapted to the control switch 303e. The movement of the connecting wire 303a pulls the traction block 303b and moves upward, so that the second contact protrusion 303d contacts the control switch 303e to start the exhaust fan 301.

[0066] The rest of the structure is the same as that of Example 2.

[0067] Operation process: When the system starts to operate, the blocking plate 201 slides through the connecting wire 303a to drive the traction block 303b to rise, and the rising traction block 303b pulls the traction ring 303c, thereby driving the positioning clamp 302d-1 to move. The movement of the positioning clamp 302d-1 opens the blocking plate 302c-2, and the filter adsorption plate 302b is exposed. When the blocking plate 201 moves, the second contact protrusion 303d on the connecting wire 303a contacts the control plate 302c-2. The control switch 303e is triggered to start the exhaust fan 301, and the exhaust fan 301 begins to suck the air inside the control cabinet body 101 to create a vacuum environment. After the system is finished running, the exhaust fan 301 is turned off, and the blocking plate 201 returns to the appropriate position. At this time, the connecting wire 303a drives the traction pull block 303b to descend, and the traction pull ring 303c then drives the positioning clamp 302d-1 to reset, the blocking plate 302c-2 is closed, and the system returns to the initial state.
