Description

Technical Field

[0001] This invention relates to the field of boiler air volume regulation technology, and in particular to a windbreak structure and its usage method that automatically adjusts the angle according to the wind force. Background Technology

[0002] Boilers are important equipment in thermal power plants. When the boiler is burning and heating hot water, the uneven distribution of air inside the boiler causes uneven combustion of fuel, resulting in an uneven temperature field distribution inside the boiler. Localized excessively high temperatures cause the products to coke, leading to the emission of incompletely combusted products.

[0003] Existing technologies have significant shortcomings in the coordinated control of air intake force and angle. Traditional air volume regulation systems mostly rely on independent damper opening adjustments, without establishing a dynamic coupling model between air force and angle. For example, when the boiler load changes, operators need to adjust the damper opening and burner angle separately, but the adjustment of the two lacks a coordinated mechanism, resulting in excessive air volume in some areas and insufficient air volume in others. Summary of the Invention

[0004] To address existing problems, this invention provides a windbreak structure and method for automatically adjusting its angle based on wind force. The aim is to automatically adjust the relative position of the windbreak and buffer plate according to wind force, thereby automatically adjusting the angle of the buffer plate and achieving effective wind force control. A pressing detection mechanism senses the wind force borne by the buffer plate and feeds it back to the control unit, which then controls the adjustment mechanism. This closed-loop control can be repeated continuously. When the wind force decreases, the spring returns to its original state. The entire process is highly automated, improving the windbreak's adaptability to different wind conditions, enhancing the windproof effect, reducing manual intervention, and increasing work efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] A windbreak structure that automatically adjusts its angle according to wind force includes a windbreak plate, a buffer plate, a pressing detection mechanism, a support column, a directional adjustment mechanism, and a control unit. The windbreak plate and the buffer plate are arranged at intervals to form gaps between them. The pressing detection mechanism and the support column are separately arranged in the gaps between the plates. The pressing detection mechanism includes a sensing pin and a spring. One end of the sensing pin is provided with a frustum, and the other end passes through a pin hole in the windbreak plate. A sensor is provided on the side of the frustum that contacts the buffer plate to sense the wind force borne by the buffer plate. The spring is sleeved on the sensing pin, with one end abutting against the frustum and the other end abutting against the windbreak plate. One end of the support column passes through a circular hole in the windbreak plate, and the other end is hinged to the buffer plate. The directional adjustment mechanism is provided on the windbreak plate to translate and shift the relative position of the windbreak plate and the buffer plate. The control unit is electrically connected to the sensor and the directional adjustment mechanism.

[0007] As a further improvement of the present invention, the directional adjustment mechanism includes a mounting base, an electric cylinder, and a sliding device; the mounting base is disposed at the position in the boiler where the wind force needs to be adjusted, and the electric cylinder is disposed on the mounting base; the sliding device includes two movable components, a first component and a second component, the first component being connected to the wind baffle, and the second component being connected to the output end of the electric cylinder.

[0008] As a further improvement of the present invention, the first component includes a mounting shaft and a gear, with the gear sleeved on the mounting shaft; the second component is a rack; the gear meshes with the rack.

[0009] As a further improvement of the present invention, the mounting shaft is disposed on the side of the wind deflector, and the side is perpendicular to the buffer plate.

[0010] As a further improvement of the present invention, the first component is a slider, one end of which is fixedly connected to the wind deflector and the other end is connected to the output end of the electric cylinder; the second component includes a slide rail; the slider cooperates with the slide rail.

[0011] As a further improvement of the present invention, the slider is disposed on the side of the wind deflector, and the side is perpendicular to the buffer plate.

[0012] As a further improvement of the present invention, the steering mechanism further includes a magnetic scale and a reading head; the output end of the electric cylinder is provided with a reading head, and the mounting base is provided with a magnetic scale, which is used to position the wind deflector by referring to the relative position of the reading head.

[0013] As a further improvement of the present invention, the area of ​​the wind deflector is greater than or equal to the area of ​​the buffer plate.

[0014] As a further improvement of the present invention, the steering mechanisms are arranged in pairs on both sides of the wind deflector.

[0015] This invention also discloses a method for using a windbreak structure that automatically adjusts its angle according to wind force, comprising the following steps: When wind force acts on the buffer plate, the buffer plate presses against the frustum of the sensing pin, and the sensor senses the wind force and transmits the signal to the control unit. The control unit controls the steering mechanism to adjust the relative position of the wind deflector and the buffer plate based on the received wind force signal.

[0016] The present invention has the following beneficial effects: This device can automatically adjust the relative position of the wind deflector and the buffer plate according to the wind force, thereby automatically adjusting the angle of the buffer plate and achieving effective control of the wind force. The pressing detection mechanism senses the wind force borne by the buffer plate and feeds it back to the control unit. The control unit then controls the adjustment mechanism to move. This closed-loop control can be repeated. When the wind force decreases, the spring can return to its original position. The whole process is highly automated, which can improve the adaptability of the wind deflector to different wind force environments, enhance the windproof effect, reduce manual intervention, and improve work efficiency.

[0017] Preferably, the first and second components are moved and shifted by an electric cylinder-driven misalignment device, thereby moving the wind deflector and adjusting the relative position of the wind deflector and the buffer plate. This structure is simple and reliable, and the electric cylinder can provide a stable driving force, which facilitates precise control of the moving distance and angle adjustment of the wind deflector.

[0018] Preferably, a rack and pinion drive is used, which ensures smooth transmission and accurate transmission ratio, guaranteeing the precision and stability of the wind deflector's movement. When adjusting the buffer plate angle, the relative position of the wind deflector and buffer plate can be controlled more precisely, improving the accuracy of wind force regulation.

[0019] Preferably, the mounting shaft is set on the side perpendicular to the buffer plate, so that the transmission direction of the gear and rack is consistent with the direction in which the wind deflector needs to move, without interfering with each other. This is beneficial to improving the efficiency and stability of the transmission, reducing energy loss and errors during the transmission process, and ensuring that the wind deflector can move and adjust its angle accurately according to the design requirements.

[0020] Preferably, the sliding block and the slide rail have a simple and low-cost matching structure, and are easy to install and maintain. This structure ensures that the wind deflector moves smoothly along the slide rail under the drive of the electric cylinder, realizing the adjustment of the relative position of the wind deflector and the buffer plate, and meeting the needs of wind force regulation.

[0021] Preferably, similar to the mounting shaft being positioned perpendicular to the side of the buffer plate, the slider is positioned perpendicular to the side of the buffer plate, so that the direction of movement of the slider is consistent with the direction that the wind deflector needs to be adjusted. This helps to improve the stability and accuracy of the wind deflector's movement and ensures the wind force regulation effect.

[0022] Preferably, the combination of the magnetic scale and the reading head enables precise measurement and positioning of the wind deflector. The control unit can more accurately control the electric cylinder's movement based on the position information fed back from the reading head, thereby precisely adjusting the relative position of the wind deflector and the buffer plate, improving the accuracy and reliability of wind force regulation.

[0023] Preferably, the area of ​​the windbreak plate is greater than or equal to the area of ​​the buffer plate. This ensures that there is sufficient wind-blocking area to effectively block the wind when the angle of the buffer plate is adjusted, thus improving the wind-blocking effect. At the same time, it can better adapt to the wind-blocking needs under different wind conditions, enhancing the versatility and practicality of the device.

[0024] Preferably, the paired directional adjustment mechanism can make the wind deflector more evenly stressed during movement and angle adjustment, avoiding problems such as tilting or jamming of the wind deflector due to unilateral stress, improving the stability and reliability of the device, ensuring that the wind deflector can be adjusted smoothly and accurately, and achieving effective control of wind force.

[0025] The method of use is simple and straightforward. Sensors detect wind speed in real time and transmit the signal to the control unit. The control unit then controls the directional mechanism to automatically adjust the angle of the windbreak structure. The entire process is highly automated, capable of quickly responding to changes in wind speed, adjusting the angle of the buffer plate in a timely manner, improving windproofing effect, reducing manual operation, lowering labor intensity, and increasing work efficiency.

[0030] Example 1 like Figure 1-3 As shown, a windbreak structure that automatically adjusts its angle according to wind force includes a windbreak plate 1, a buffer plate 4, a pressing detection mechanism, a support column, a directional adjustment mechanism 6, and a control unit. The windbreak plate 1 and the buffer plate 4 are arranged at intervals to form gaps between the plates. The pressing detection mechanism and the support column are separately arranged in the gaps between the plates. The pressing detection mechanism includes a sensing pin 5 and a spring. One end of the sensing pin 5 is provided with a frustum, and the other end passes through a pin hole on the windbreak plate 1. A sensor 12 is provided on the side of the frustum that contacts the buffer plate 4 to sense the wind force borne by the buffer plate 4. The spring is sleeved on the sensing pin 5, with one end abutting against the frustum and the other end abutting against the windbreak plate 1. One end of the support column passes through a circular hole on the windbreak plate 1, and the other end is hinged to the buffer plate 4. The directional adjustment mechanism 6 is provided on the windbreak plate 1 to translate and shift the relative position of the windbreak plate 1 and the buffer plate 4. The control unit is electrically connected to the sensor 12 and the directional adjustment mechanism 6, respectively.

[0031] The directional adjustment mechanism 6 includes a mounting base 9, an electric cylinder 8, and a sliding device; the mounting base 9 is located in the boiler at the position where the air force needs to be adjusted, and the electric cylinder 8 is installed on the mounting base 9; the sliding device includes two components that can be moved and slidably, the first component is connected to the wind baffle 1, and the second component is connected to the output end of the electric cylinder 8.

[0032] The first component includes a mounting shaft 2 and a gear 3, with the gear 3 mounted on the mounting shaft 2; the second component is a rack 7; the gear 3 meshes with the rack 7.

[0033] The mounting shaft 2 is located on the side of the wind deflector 1, with the side perpendicular to the buffer plate 4.

[0034] Preferably, such as Figure 2 As shown, the steering mechanism 6 also includes a magnetic scale 10 and a reading head 11; the output end of the electric cylinder 8 is provided with a reading head 11, and the mounting base 9 is provided with a magnetic scale 10. The magnetic scale 10 is used to position the windshield 1 by referring to the relative position of the reading head 11.

[0035] The area of ​​the wind deflector 1 is greater than or equal to the area of ​​the buffer plate 4.

[0036] The directional adjustment mechanism 6 is arranged in pairs on both sides of the wind deflector 1.

[0037] This embodiment also discloses a method for using a windbreak structure that automatically adjusts its angle according to wind force, including the following steps: When the wind force acts on the buffer plate 4, the buffer plate 4 presses the frustum of the sensing pin 5, and the sensor 12 senses the wind force and transmits the signal to the control unit. The control unit controls the directional mechanism 6 to operate based on the received wind force signal, adjusting the relative position of the wind deflector 1 and the buffer plate 4.

[0038] The working principle of this embodiment is as follows: When it is necessary to automatically adjust the angle of the windbreak structure according to the wind force, the mounting shaft 2 of the windbreak plate 1 is inserted into the corresponding position of the boiler, and the mounting base 9 is fixedly connected to the corresponding position of the boiler. When the windbreak structure is used: before the ventilation mechanism introduces air into the boiler, the air inlet first contacts the buffer plate 4, and the buffer plate 4 compresses the sensing pin 5. During this process, the buffer plate 4 generates pressure on the sensor 12, and the sensor 12 transmits the pressure signal to the control unit. When the temperature inside the boiler is uneven and it is necessary to adjust the position of the windbreak plate 1, under the control of the control unit, the push rod of the electric cylinder 8 extends or retracts, driving the rack 7 to move. The rack 7 meshes with the gear 3 at the end of the mounting shaft 2. The two devices work together to cause relative movement between the wind deflector 1 and the buffer plate 4. During this process, the reading head 11 and the magnetic scale 10 work together to determine the extension distance of the push rod of the electric cylinder 8 and transmit the reading to the control unit. At the same time, the sensor 12 transmits the pressure change signal to the control unit. The control unit combines the pressure transmitted by the sensor 12, the signal transmitted by the reading head 11, and the signal of the extension distance of the electric cylinder 8 with the set value of the adjustment angle. For example, by using a PID control model, the action of the electric cylinder 8 is dynamically adjusted according to the pressure change trend and position feedback, thereby correcting the extension distance of the electric cylinder 8 so that the wind deflector 1 can be precisely adjusted, thereby adjusting the angle between the buffer plate 4 and the wind deflector 1. The above process is maintained until the work is completed.

[0039] Example 2 The difference between this embodiment and Embodiment 1 is that: 1) The first component is a slider, one end of which is fixedly connected to the wind deflector 1 and the other end is connected to the output end of the electric cylinder 8; the second component includes a slide rail; the slider and the slide rail cooperate with each other.

[0040] 2) The slider is set on the side of the wind deflector 1, and the side is perpendicular to the buffer plate 4.
