Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a solar-powered device for preventing backflow of flue gas. Background Technology

[0002] In modern building design, especially in high-rise buildings and enclosed structures, the design of smoke extraction systems plays a crucial role in ensuring indoor air quality and occupant safety. Traditional smoke extraction devices are prone to backflow of smoke during inclement weather (such as strong winds or rain) or under special external conditions, causing the exhausted smoke to flow back into the room. This not only affects the indoor air environment but may also pose a threat to residents' health and safety.

[0003] Existing smoke backflow prevention devices typically rely on mechanical structures or single valves to block external airflow, but their effectiveness is limited in the face of strong winds or unstable wind directions. Furthermore, most of these devices are electrically powered, increasing energy consumption and reducing the system's energy-saving performance. Given the increasingly stringent requirements for building energy efficiency, developing an energy-saving, environmentally friendly smoke extraction device that effectively prevents smoke backflow is of paramount importance. Summary of the Invention

[0004] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a solar-powered device for preventing backflow of flue gas. It uses solar energy as a driving force to achieve self-powered operation, reduce reliance on traditional electricity, and effectively prevent backflow of flue gas through optimized structural design, thereby improving the safety and reliability of the exhaust system.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A solar-powered device for preventing backflow of flue gas includes a solar power module, a flue gas monitoring module, and a powered exhaust module. The solar power module converts solar energy into electrical energy through a solar photovoltaic panel 10 and stores it in a battery 11. The flue gas monitoring module includes a controller 13 and a speed sensor 14 located near the flue outlet. The powered exhaust module includes a motor 15 located above the flue outlet and an exhaust assembly driven by it. The battery 11 is electrically connected to both the flue gas monitoring module and the powered exhaust module, providing power to the controller 13, the speed sensor 14, and the motor 15.

[0007] The signal receiving end of the controller 13 is connected to the signal output end of the speed sensor 14, and the signal output end of the controller 13 is connected to the signal receiving end of the motor controller to control the operation of the motor 15.

[0008] The exhaust assembly includes a first gear 9, the center of which is connected to the power output shaft of the motor 15. The first gear 9 meshes with a second gear 8, the center of which is connected to one end of the longitudinal shaft 5. The other end of the longitudinal shaft 5 passes through the base plate 16 and is connected to the middle section of the transverse shaft 3. One end of the transverse shaft 3 is connected to a first baffle 2, and the other end is connected to a second baffle 4.

[0009] The motor 15 is fixedly connected to the base plate 16 via a motor support frame.

[0010] The battery 11 and the solar photovoltaic panel 10 are both installed on the base plate 16, which is installed on the top of the bracket 1, and the bracket 1 is installed on the top of the chimney.

[0011] The longitudinal axis 5 is a stepped axis, with its large end connected to the base plate 16 via bearing 7 and its small end connected to the transverse axis 3 via pin.

[0012] The second gear 8 is mounted above the bearing 7, and the second gear 8 is fixed to the longitudinal shaft 5 by a key and a nut.

[0013] The first baffle 2 is axially connected to the horizontal axis 3, and the second baffle 4 is radially connected to the horizontal axis 3. The first baffle 2 and the second baffle 4 are perpendicular to each other.

[0014] The second baffle 4 has an arc-shaped surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This device, through the coordinated movement of the first and second baffles, effectively blocks the external airflow when the flue gas flow is obstructed or flows against the flow, forming a negative pressure so that the flue gas can be discharged smoothly and backflow is avoided.

[0017] 2. This device utilizes solar panels and batteries to generate electricity, reducing reliance on traditional power sources. Even in situations where the external power supply is unstable, the device can still operate normally, demonstrating high energy efficiency and meeting the energy-saving requirements of modern buildings.

[0018] 3. This device is equipped with a speed sensor to monitor the flue gas velocity in real time. When the flue gas velocity is low, the motor is automatically started, and the baffle is driven by gear transmission to ensure the device's rapid response and stable operation. It is especially suitable for the smoke exhaust needs of high-rise buildings and enclosed structures.

[0019] 4. The mechanical structure of this device is reasonably designed. It achieves stable installation and precise transmission through bearings, pins, gears, etc., which facilitates maintenance and replacement and extends the service life of the equipment.

[0020] Through the above improvements, this utility model is superior to traditional smoke exhaust devices in terms of preventing backflow of smoke, energy saving and environmental protection, and adaptability, significantly improving the safety of buildings and air quality.

Detailed Implementation

[0026] The specific embodiments disclosed herein will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.

[0027] like Figures 1 to 3 As shown, this utility model includes a solar-powered device for preventing backflow of flue gas, comprising a solar power module, a flue gas monitoring module, and a powered exhaust module. The solar power module converts solar energy into electrical energy through a solar photovoltaic panel 10 and stores it in a battery 11, ensuring that the device can supply power autonomously under sunlight conditions, achieving the purpose of energy conservation and environmental protection. The flue gas monitoring module includes a controller 13 and a speed sensor 14 installed near the flue outlet. The powered exhaust module includes a motor 15 installed above the flue outlet and its driven exhaust components. The battery 11 is electrically connected to the flue gas monitoring module and the powered exhaust module, respectively, to supply power to the controller 13, the speed sensor 14, and the motor 15.

[0028] The signal receiving end of the controller 13 is connected to the signal output end of the speed sensor 14 to detect the flow rate of flue gas inside the chimney. The signal output end of the controller 13 is also connected to the signal receiving end of the motor controller to control the operation of the motor 15. When the speed sensor 14 detects that the flue gas flow rate is lower than a set threshold, the controller 13 automatically starts the motor 15, putting the device into working condition. At this time, the motor 15 drives the gear transmission mechanism to rotate, and the vertical shaft 5 and the horizontal shaft 3 rotate, driving the baffle to move, thereby creating a negative pressure inside the chimney, pushing the flue gas outward and preventing backflow of flue gas.

[0029] The exhaust assembly includes a first gear 9, the center of which is connected to the power output shaft of the motor 15. The first gear 9 meshes with a second gear 8, the center of which is connected to one end of the longitudinal shaft 5. The other end of the longitudinal shaft 5 passes through the base plate 16 and is connected to the middle section of the transverse shaft 3. One end of the transverse shaft 3 is connected to a first baffle 2, and the other end is connected to a second baffle 4.

[0030] The motor 15 is fixedly connected to the base plate 16 via a motor support frame.

[0031] The battery 11 and the solar photovoltaic panel 10 are both installed on the base plate 16, which is installed on the top of the bracket 1, and the bracket 1 is installed on the top of the chimney.

[0032] The longitudinal axis 5 is a stepped axis, with its large end connected to the base plate 16 via bearing 7 and its small end connected to the transverse axis 3 via pin.

[0033] The second gear 8 is mounted above the bearing 7 and is fixed to the vertical shaft 5 by a key and a nut; the bearing 7 is fixed by the bearing bottom cover 17, thereby ensuring that the vertical shaft 5 can rotate smoothly under high load conditions.

[0034] The working principle of this utility model is as follows:

[0035] The solar power module converts solar energy into electrical energy through solar photovoltaic panels 10 and stores it in a storage battery 11. The storage battery provides power to the motor. The controller 13 works in conjunction with the speed sensor 14 to detect the flow rate of flue gas inside the chimney. When the speed sensor 14 detects that the flue gas flow rate is lower than a set threshold, the controller 13 automatically starts the motor 15, putting the device into working condition. At this time, the motor 15 drives the gear transmission mechanism to rotate. When the motor starts, it transmits power to the second gear 8 through the first gear 9, which in turn drives the vertical shaft 5 and the horizontal shaft 3 to rotate. The rotation of the horizontal shaft 3 causes the first baffle 2 and the second baffle 4 to move, thereby creating a negative pressure inside the chimney to guide the flue gas out and prevent backflow of flue gas.

[0036] This utility model smoke exhaust device can automatically start when the smoke flow rate is low or backflow occurs. It relies on a solar power system to effectively reduce dependence on traditional electricity, and the movement of the baffle system can prevent smoke backflow, ensuring indoor air quality and achieving the goal of energy conservation and environmental protection.
