Description

Technical Field

[0001] The utility model relates to the technical field of fan fire protection, in particular to an automatic fire protection device for a fan. Background Art

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy is a clean, pollution-free, renewable energy source. Wind turbines generate heat during use. If the heat cannot be dissipated in time, the wind turbines may catch fire. Fire-fighting equipment is required to automatically detect, alarm, and extinguish fires in the turbines.

[0003] When a fire occurs inside the chamber of the fan, it is generally because there are too many connecting wires and devices in the control cabinet, and the heat cannot be dissipated in time, resulting in an internal fire. Since the control cabinet is protected by a shell outside, even if the external ultra-fine dry powder fire extinguisher can be activated in time, it cannot directly reach the fire source for targeted fire extinguishing, so the fire extinguishing efficiency is greatly reduced. Therefore, a fan automatic fire fighting device is proposed to address the above problems. Utility Model Content

[0004] The purpose of the present utility model is to provide an automatic fire-fighting device for a fan to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] As an optional solution of the fan automatic fire-fighting device described in the utility model, wherein: an automatic fire-fighting device for a fan comprises a fan, wherein the interior of the fan is fixedly connected to a control cabinet, the top of the control cabinet is fixedly connected to a rotary spraying assembly, the top of the rotary spraying assembly is connected to a fire-fighting assembly, and the outer side of the fire-fighting assembly is fixedly connected to the fan;

[0007] The firefighting assembly includes a mounting frame, an ultra-fine dry powder fire extinguishing bottle, and a blocking frame. The outer side of the mounting frame is fixedly connected to the fan, the inner side of the mounting frame is fixedly connected to the ultra-fine dry powder fire extinguishing bottle, the bottom of the ultra-fine dry powder fire extinguishing bottle is connected to the blocking frame, and the bottom of the blocking frame is connected to the rotary spraying assembly;

[0008] The inside of the mounting frame is fixedly connected to a motor, the end of the main shaft of the motor is fixedly connected to a threaded shaft, the outer side of the threaded shaft is spirally connected to a threaded sleeve, the other end of the threaded sleeve is fixedly connected to a blocking block, the outer side of the blocking block is slidably connected to the blocking frame, and a docking block is provided at the other end of the blocking block, and the outer side of the docking block is fixedly connected to the mounting block, and the outer side of the mounting block is fixedly connected to the mounting frame.

[0009] When a fire occurs inside the chamber of the fan, it is generally because the control cabinet has many connecting wires and many devices, and the heat cannot be dissipated in time, resulting in an internal fire. Since the control cabinet is protected by a shell, even if the external ultra-fine dry powder fire extinguisher can be activated in time, it cannot directly reach the fire source for targeted fire extinguishing, so the fire extinguishing efficiency is greatly reduced. When the device is used, an external power supply is connected. A rotating spray assembly and a fire fighting assembly are set on the top of the control cabinet. When a fire occurs inside the control cabinet, the threaded shaft is driven to rotate by the starting motor, and the threaded shaft drives the threaded sleeve to move, and the threaded sleeve drives the blocking block to move. At this time, the discharge hole of the blocking block is aligned with the discharge hole of the ultra-fine dry powder fire extinguishing bottle. At this time, the fire extinguishing agent inside the ultra-fine dry powder fire extinguishing bottle can be directly discharged through the rotating spray assembly. At this time, targeted fire extinguishing can be carried out inside the control cabinet, and its fire extinguishing quality is guaranteed. When the blocking block moves, one end of the blocking block contacts the docking block. At this time, it can be ensured that the discharge hole of the blocking block is accurately aligned with the discharge hole of the ultra-fine dry powder fire extinguishing bottle, ensuring that the fire extinguishing agent is discharged.

[0010] As an optional solution of the automatic fire-fighting device for a fan described in the utility model, the outer side of the blocking block is slidably connected to the blocking frame, and a sealing plate is fixedly connected to the top of the blocking block.

[0011] When the blocking block moves, a sealing plate is provided above the blocking block, which can block the discharge hole of the ultra-fine dry powder fire extinguishing bottle. At this time, the fire extinguishing agent is not easy to fall, thereby preventing the fire extinguishing agent from being discharged.

[0012] As an optional solution of the automatic fire-fighting device for a fan described in the utility model, the bottom of the threaded sleeve is fixedly connected to a sliding frame, the interior of the sliding frame is slidably connected to a guide block, and the bottom of the guide block is fixedly connected to the installation frame.

[0013] When the threaded sleeve moves, the cooperation between the sliding frame and the guide block can ensure the stable movement of the threaded sleeve and prevent the threaded sleeve from rotating itself.

[0014] As an optional solution of the automatic fire-fighting device of a fan described in the utility model, the rotating spraying assembly includes a fixed frame, a connecting cylinder and a hollow tube, the top of the fixed frame is fixedly connected to the connecting cylinder, the top of the connecting cylinder is fixedly connected to the fire-fighting assembly, a hollow tube is provided inside the connecting cylinder, the top of the hollow tube is connected to the sealing frame of the fire-fighting assembly, the bottom of the hollow tube is rotatably connected to a rotating hollow frame, and the bottom of the rotating hollow frame is connected to evenly distributed nozzles.

[0015] As an optional solution of the automatic fire-fighting device for a fan described in the utility model, the nozzles are arranged in multiple groups and are arranged at an angle.

[0016] When the fire extinguishing agent is discharged, it enters the rotating hollow frame through the hollow tube and is then discharged through the nozzle. Since the nozzle is tilted, the rotating hollow frame can be driven to rotate when the fire extinguishing agent is discharged. At this time, the rotating hollow frame can rotate under the push of the fire extinguishing agent, ensuring that the fire extinguishing agent is fully sprayed into the control cabinet for comprehensive fire extinguishing treatment.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model is provided with a rotary spraying assembly and a fire-fighting assembly on the top of the control cabinet. When a fire occurs inside the control cabinet, the threaded shaft is driven to rotate by starting the motor, and the threaded shaft drives the threaded sleeve to move, and the threaded sleeve drives the blocking block to move. At this time, the discharge hole of the blocking block is aligned with the discharge hole of the ultra-fine dry powder fire extinguishing bottle. At this time, the fire extinguishing agent in the ultra-fine dry powder fire extinguishing bottle can be directly discharged through the rotary spraying assembly. At this time, targeted fire extinguishing treatment can be carried out inside the control cabinet, and the fire extinguishing quality is guaranteed.

[0019] When the fire extinguishing agent is discharged, it enters the rotating hollow frame through the hollow tube and is then discharged through the nozzle. Since the nozzle is tilted, the rotating hollow frame can be driven to rotate when the fire extinguishing agent is discharged. At this time, the rotating hollow frame can rotate, ensuring that the fire extinguishing agent is fully sprayed into the control cabinet to carry out comprehensive fire extinguishing treatment.

[0020] When the blocking block moves, one end of the blocking block contacts the docking block, which can ensure that the discharge hole of the blocking block is accurately aligned with the discharge hole of the ultra-fine dry powder fire extinguisher bottle, ensuring that the fire extinguishing agent is discharged. At the same time, the guide block and the sliding frame are coordinated to ensure that the threaded sleeve moves stably. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the utility model provides a technical solution:

[0030] An automatic fire-fighting device for a fan comprises a fan 1, wherein a control cabinet 2 is fixedly connected to the interior of the fan 1, a rotary spray assembly 3 is fixedly connected to the top of the control cabinet 2, a fire-fighting assembly 4 is connected above the rotary spray assembly 3, and the outer side of the fire-fighting assembly 4 is fixedly connected to the fan 1;

The bottom of the ultra-fine dry powder fire extinguishing bottle 402 is connected to the blocking frame 403, and the bottom of the blocking frame 403 is connected to the rotating spraying assembly 3.

[0032] The interior of the above-mentioned installation frame 401 is fixedly connected to a motor 406, the end of the main shaft of the above-mentioned motor 406 is fixedly connected to a threaded shaft 407, the outer side of the above-mentioned threaded shaft 407 is spirally connected to a threaded sleeve 408, the other end of the above-mentioned threaded sleeve 408 is fixedly connected to a blocking block 409, the outer side of the above-mentioned blocking block 409 is slidably connected to the blocking frame 403, and the other end of the blocking block 409 is provided with a docking block 405, and the outer side of the docking block 405 is fixedly connected to the installation block 404, and the outer side of the above-mentioned installation block 404 is fixedly connected to the installation frame 401.

[0033] When a fire occurs inside the chamber of the fan, it is usually because there are too many connecting wires and devices in the control cabinet, and the heat cannot be dissipated in time, resulting in an internal fire. Since the control cabinet is protected by a shell, even if the external ultra-fine dry powder fire extinguisher can be activated in time, it cannot directly reach the fire source for targeted fire extinguishing, so the fire extinguishing efficiency is greatly reduced. When the device is used, an external power supply is connected. A rotating spray component 3 and a fire fighting component 4 are set on the top of the control cabinet 2. When a fire occurs inside the control cabinet 2, the threaded shaft 407 is driven to rotate by the starting motor 406, and the threaded shaft 407 drives the threaded sleeve 40 8 moves, and the threaded sleeve 408 drives the blocking block 409 to move.

At this time, targeted fire extinguishing treatment can be carried out inside the control cabinet 2, and its fire extinguishing quality is guaranteed. When the blocking block 409 moves, one end of the blocking block 409 contacts the docking block 405. At this time, it can be ensured that the discharge hole of the blocking block 409 is accurately aligned with the discharge hole of the ultra-fine dry powder fire extinguishing bottle 402, ensuring that the fire extinguishing agent is discharged.

[0034] Example 2

[0035] This embodiment is an improvement on embodiment 1. Figure 2 and Figure 3 Specifically, the outer side of the blocking block 409 is slidably connected to the blocking frame 403 , and the top of the blocking block 409 is fixedly connected with a sealing plate 412 .

[0036] When the blocking block 409 moves, a sealing plate 412 is provided above the blocking block 409 . The sealing plate 412 can block the discharge hole of the ultra-fine dry powder fire extinguishing bottle 402 . At this time, the fire extinguishing agent is not easy to fall, thereby preventing the fire extinguishing agent from being discharged.

[0037] Example 3

[0038] This embodiment is an improvement on embodiment 2. Figure 2 Specifically, the bottom of the threaded sleeve 408 is fixedly connected to a sliding frame 410 , the interior of the sliding frame 410 is slidably connected to a guide block 411 , and the bottom of the guide block 411 is fixedly connected to the mounting frame 401 .

[0039] When the threaded sleeve 408 moves, the sliding frame 410 and the guide block 411 provided therein cooperate to ensure that the threaded sleeve 408 moves stably and prevents the threaded sleeve 408 from rotating itself.

The bottom of the hollow tube 303 is rotatably connected to a rotating hollow frame 304. The bottom of the rotating hollow frame 304 is connected to evenly distributed nozzles 305.

[0042] The nozzles 305 are arranged in multiple groups, and the nozzles 305 are arranged at an angle.

[0043] When the fire extinguishing agent is discharged, it enters the rotating hollow frame 304 through the hollow tube 303 and is then discharged through the nozzle 305. Since the nozzle 305 is arranged at an angle, the rotating hollow frame 304 can be driven to rotate when the fire extinguishing agent is discharged. At this time, the rotating hollow frame 304 can rotate under the promotion of the fire extinguishing agent, thereby ensuring that the fire extinguishing agent is fully sprayed into the interior of the control cabinet for comprehensive fire extinguishing treatment.
