DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] Example: See Figure 1-4The utility model provides a technical solution: a fire-fighting smoke exhaust device, including a smoke exhaust pipe 1 and a blast assembly 2 provided on the side thereof, a mounting bracket 6 is connected in the smoke exhaust pipe 1, a filter screen 5 is connected in the smoke exhaust pipe 1, the mounting bracket 6 is rotatably connected to a rotating shaft 7, one end of the rotating shaft 7 is connected to a dust cleaning component 8, the dust cleaning component 8 includes a connecting member 801, the connecting member 801 is connected to the rotating shaft 7, the connecting member 801 is connected to two inclined sliding brackets 802, the sliding bracket 802 is provided with a sliding groove, the sliding bracket 802 slides The sliding member 803 is movably connected, and the bottom of the sliding member 803 is slidably connected to the inner wall of the sliding groove. The top of the sliding bracket 802 is slidably connected to the spring bracket 804. The spring bracket 804 is provided with a waist-shaped hole that penetrates through. The top of the sliding member 803 passes through the waist-shaped hole of the spring bracket 804. The top of the spring bracket 804 is connected to a spring 805, and the spring 805 is connected to the outer side of the top of the sliding member 803. The two ends of the spring bracket 804 are connected to scraper brackets 806, and the scraper bracket 806 is connected to a scraper 807, and the scraper 807 faces the direction of the filter screen 5;

[0025] The structure of the dust cleaning component 8 can make the spring bracket 804 slide in the direction away from the mounting bracket 6 by the rotating centrifugal force, so that the scraper 807 contacts the side of the filter 5, thereby achieving the filtering effect of the device. The elastic sliding scraper 807 structure of the device can avoid blocking the filter 5 under normal circumstances, and avoid the problem of the filter 5 passing efficiency being reduced due to the dust cleaning component 8.

[0026] Furthermore, a connecting plate is provided at the top center of the spring bracket 804 , the connecting plate is connected to the spring 805 , a wear-resistant layer is provided on the surface of the scraper 807 , a clamping groove is provided on the side of the scraper bracket 806 , and the inner wall of the clamping groove is connected to the scraper 807 .

[0027] Further, a through hole is provided at the bottom of the smoke exhaust duct 1, and an ash box 3 is connected to the bottom of the smoke exhaust duct 1. The ash box 3 is arranged below the filter 5. The air blowing assembly 2 includes a blower, and the blower is connected to the smoke exhaust duct 1. A mounting groove is provided at the bottom of the outer side of the smoke exhaust duct 1. A mounting buckle is connected to the top of the ash box 3, and the mounting buckle is connected to the mounting groove. The ash box 3 is provided with a sealing member, and the sealing member is arranged at the joint l between the ash box 3 and the smoke exhaust duct 1;

[0028] Specifically, a connection seal is provided at one end of the smoke exhaust pipe 1 away from the air blowing assembly 2, and a gap exists between the turbine fan 4 and the inner wall of the smoke exhaust pipe 1;

[0029] The structure of the ash box 3 can collect the dust scraped off the surface of the filter 5 by the scraper 807. During the maintenance process, the staff can quickly clean the dust by disassembling the ash box 3, thereby improving the maintenance efficiency of the device. The structure of the blower can ensure the stability of the wind pressure during the smoke exhaust process of the device.

[0030] The end of the rotating shaft 7 away from the dust cleaning component 8 is connected to the turbofan 4, the mounting bracket 6 is connected to the resilient component 9, the resilient component 9 includes a rack 903, the side of the mounting bracket 6 is connected to an elastic telescopic rod 902, the elastic telescopic rod 902 is connected to the rack 903, the rotating shaft 7 is connected to a gear 901, the gear 901 is meshed and connected to the rack 903, and the rack 903 is slidably connected to the mounting bracket 6;

[0031] Through the structure of the turbofan 4, it can rotate under the transmission of aerodynamic force when the blower assembly 2 of the device is in use. The rotation of the turbofan 4 can realize the sliding of the rack 903 and then the compression effect of the elastic telescopic rod 902 through the combination of the rotating shaft 7 and the gear 901, thereby storing elastic potential energy. After the blower assembly 2 stops working and the air circulation inside the smoke exhaust duct 1 stops, the elastic telescopic rod 902 is released, thereby driving the turbofan 4 to reverse. At this time, the rotating shaft 7 rotates to generate centrifugal force, thereby driving the spring bracket 804 to slide, thereby achieving the effect of automatic cleaning of the device after the smoke exhaust is completed.

[0032] The automated cleaning effect of the device can effectively avoid problems such as reduced exhaust efficiency due to long-term dust clogging the filter 5, and at the same time, the structure of the dust box 3 can improve the cleaning efficiency of the device and reduce the maintenance difficulty of the device.

[0033] When the device is in working condition, the blower inside the blower assembly 2 starts to rotate, thereby achieving the effect of exhausting smoke outward from the device. A one-way airflow can be formed inside the smoke exhaust duct 1 through the blower. At this time, dust particles in the smoke are intercepted when the smoke passes through the filter 5, thereby preventing dust from polluting the air environment. During the operation of the blower, the aerodynamic principle is used to drive the turbofan 4 to rotate when the airflow passes through the turbofan 4. When the turbofan 4 rotates, the gear 901 can be driven to rotate through the rotating shaft 7. The rotation of the gear 901 drives the rack 903 to slide, thereby compressing the elastic telescopic rod 902. The symmetrical elastic telescopic rods 902 on both sides are respectively in a state of compression and tension. At this time, the elastic telescopic rod 902 stores elastic potential energy. At the same time, the elastic force generated by the elastic telescopic rod 902 is balanced with the air rotation force of the turbofan 4. At this time, the turbofan 4 is in a stationary state.

[0034] When the blower assembly 2 stops working, the turbofan 4 loses the support of the air rotation force, and the elastic potential energy inside the elastic telescopic rod 902 is released. The rack 903 is driven to slide through the elastic telescopic rod 902, and then the turbofan 4 is driven to rotate through the combination of the gear 901 and the rotating shaft 7. When the rotating shaft 7 rotates, the two sliding members 803 can be thrown out in the direction away from the mounting bracket 6 when the rotating shaft 7 drives the connecting member 801 and the two sliding brackets 802 to rotate through the rotational centrifugal force. The sliding of the sliding member 803 away from the mounting bracket 6 can drive the spring bracket 804 to slide away from the mounting bracket 6. The spring bracket 804 is connected to the two scraper brackets 806, so that when the spring bracket 804 slides away from the mounting bracket 6, the scraper bracket 806 and the scraper 807 are close to the filter screen 5, and then the scraper 807 contacts the surface of the filter screen 5. The two scrapers 807 revolve under the drive of the rotating shaft 7 while contacting the filter screen 5, thereby achieving cleaning of the surface of the filter screen 5.

[0035] When the blower assembly 2 is just started, the cleaning component 8 of the device will also make the scraper 807 contact the surface of the filter 5. However, when the filter 5 has just been used, there is no dust accumulation on the surface, so the scraper 807 that has just been started has no cleaning effect.

[0036] After the elastic telescopic rod 902 is fully released, the rotating shaft 7 gradually slows down and tends to be stationary. As the rotation speed of the rotating shaft 7 decreases, the centrifugal force decreases, so that the spring bracket 804 slides toward the mounting bracket 6 under the drive of the spring 805. At this time, the scraper 807 is away from the side of the filter screen 5, thereby achieving a complete cleaning effect, avoiding long-term contact between the scraper 807 and the filter screen 5, and avoiding the scraper 807 reducing the filtration efficiency of the filter screen 5.

[0037] The dust scraped off by the scraper 807 will enter the dust box 3. The device can achieve the maintenance effect of the device by regularly cleaning the dust box 3 and regularly replacing the scraper 807 structure, thereby reducing the maintenance difficulty of the device.
