Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinets, specifically a new type of energy-saving low-voltage intelligent power distribution cabinet based on smart grids. Background Technology

[0002] In industrial production activities, low-voltage power distribution systems are the power hub that ensures equipment operation and maintains production continuity. As the core carrier of this system, the performance of low-voltage switchgear not only directly affects the stability of power supply, but is also deeply linked to the energy consumption, operation and maintenance efficiency and intelligent transformation process of industrial enterprises.

[0003] A patent application with publication number CN118539299A discloses an intelligent power distribution cabinet, including a cabinet body, a door installed on one side of the cabinet body, four heat dissipation slots on the outer wall of the cabinet body, a moisture-proof seat fixedly installed at the bottom of the cabinet body, and a frame fixedly installed on the side wall of the cabinet body. A heat dissipation mechanism, including a fan, is provided on one side of the frame. Through the cooperation of the fan and the heat dissipation slots, efficient convection circulation of air inside and outside the cabinet body is achieved, which quickly removes the heat generated by the electrical components inside the cabinet, thereby maintaining a stable and suitable operating temperature inside the cabinet.

[0004] The above-mentioned scheme has certain limitations when applied in coastal areas. Due to factors such as the thermal difference between land and sea, the distribution of land and sea topography, and atmospheric circulation, coastal areas often have natural winds that last for a long time and have a high average wind force. However, the fans in the existing scheme can only operate at a single wind speed and cannot dynamically adjust the wind speed according to the strength of the external natural wind. Maintaining a fixed wind speed by the fans can easily lead to energy waste.

[0005] Therefore, the present invention provides a novel energy-saving low-voltage intelligent power distribution cabinet for industrial applications based on smart grids. Summary of the Invention

The adjustment component includes: a controller disposed inside the cabinet body and electrically connected to the fan, used to adjust the fan speed according to an input signal; a first rod installed inside the cabinet body; and a square rod slidably installed on the cabinet body. A pressure sensor is disposed on the square rod, located between the square rod and the first rod, and connected to the controller. The wind power detection component senses external wind force and converts it into mechanical displacement to drive the square rod to move, the amount of movement being related to the wind force.

[0008] Preferably, the adjustment assembly further includes: a square shell mounted on the cabinet, a sliding plate slidably mounted inside the square shell, a thermal expansion material installed between the square shell and the sliding plate, a first rod fixedly mounted on the sliding plate, and a spring installed between the first rod and the square shell.

[0010] Preferably, the driving structure includes: a lead screw for driving the square rod to move, the lead screw being rotatably mounted on the cabinet, and the square rod being threadedly connected to the lead screw; a worm gear for driving the lead screw to rotate, the worm gear being fixedly mounted on the lead screw; a worm gear for driving the worm gear to rotate; a first round rod rotatably mounted on the cabinet, the worm gear being fixedly mounted on the first round rod, and a gear being fixedly mounted on the first round rod; and a rack plate for driving the gear to rotate, the rack plate being fixedly mounted on the arc-shaped plate.

[0011] Preferably, the travel distance of the square rod is less than the travel distance of the sliding plate.

[0012] Preferably, the heat dissipation assembly further includes: two filters installed on the cabinet; a second circular shaft rotatably installed on the cabinet; and two connecting plates symmetrically fixed on the fan, wherein the second circular shaft is connected to the connecting plates.

[0013] Preferably, the adjustment assembly further includes: a baffle fixedly installed on the arc-shaped plate; a connecting block and a limiting plate, wherein the limiting plate is rotatably connected to the connecting block, and a torsion spring is installed between the limiting plate and the connecting block; two second round rods rotatably installed on the cabinet, wherein the second round rods are provided with sliding grooves, and the connecting block has protrusions that are slidably connected to the sliding grooves; and a delay structure for driving the second round rods to rotate.

[0014] Preferably, the delay structure includes: a second gear fixedly mounted on the second round rod; a third gear fixedly mounted on the first round shaft; a gear set rotatably mounted on the cabinet, the third gear intermittently driving the second gear to rotate through the gear set; and a third spring mounted between the connecting block and the second round rod.

[0015] Preferably, the wind detection component further includes: a wind-catching plate slidably mounted on the cabinet; a T-shaped rod rotatably mounted on the cabinet, on which two sensors are mounted, and the two sensors are electrically connected to the controller; and a ring slidably mounted on the cabinet, the ring being threadedly connected to the T-shaped rod.

[0016] Preferably, the heat dissipation assembly further includes: a socket formed on the connecting plate; and a plurality of electrically operated telescopic rods for inserting into the socket to position the connecting plate.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a novel energy-saving low-voltage intelligent power distribution cabinet based on a smart grid. Through the cooperation of a wind power detection component and a pressure sensor, the fan speed can be dynamically adjusted according to the strength of the external natural wind, maximizing the use of the abundant natural wind resources in coastal areas to assist in heat dissipation, and significantly reducing the ineffective energy consumption of the fan while maintaining the same heat dissipation effect.

[0018] 2. The present invention discloses a novel energy-saving low-voltage intelligent power distribution cabinet based on a smart grid. By setting a delay structure, it filters out occasional short-term gusts and turbulence in coastal areas, avoiding accidental sliding of the arc plate and mismovement of the square rod due to instantaneous wind fluctuations. This prevents frequent changes in pressure signals from causing repeated adjustments to the fan speed, ensuring that the fan speed adjustment is only for continuous and effective natural wind. This avoids ineffective energy consumption fluctuations and ensures stable temperature inside the cabinet, preventing fluctuating heat dissipation efficiency due to frequent switching of wind speed.

[0019] 3. The present invention discloses a novel energy-saving low-voltage intelligent power distribution cabinet based on a smart grid. By rotating a fan, it ensures that the airflow inside the cabinet is always synchronized with the external wind direction, avoiding interference from strong external winds on the airflow circulation inside the cabinet and aiding in heat dissipation. On the other hand, the rotation of the fan changes the direction of the airflow acting on the filter screen. This change in airflow direction can blow away the dust accumulated on the filter screen, thereby helping to keep the filter screen clean and maintain its filtration performance.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1-10 As shown in the figure, an industrial new energy-saving low-voltage intelligent power distribution cabinet based on smart grid according to an embodiment of the present invention includes a cabinet body 1, a heat dissipation component 2, a wind force detection component 3, and an adjustment component 4. The cabinet body 1 has heat dissipation vents 5 on opposite side walls. The heat dissipation component 2 includes a fan 21 installed at the heat dissipation vent 5. The adjustment component 4 includes: a controller 41 disposed inside the cabinet body 1 and electrically connected to the fan 21, used to adjust the speed of the fan 21 according to the input signal; a first rod 42 installed inside the cabinet body 1; and a square rod 43 slidably installed on the cabinet body 1. A pressure sensor 44 is disposed on the square rod 43, and the pressure sensor 44 is located between the square rod 43 and the first rod 42. The pressure sensor 44 is connected to the controller 41. The wind force detection component 3 is used to sense the external wind force and convert it into mechanical displacement to drive the square rod 43 to move. The amount of movement is related to the wind force.

[0024] Specifically, the existing technology has certain limitations when applied in coastal areas. Due to factors such as the difference in thermal energy between land and sea, the distribution of land and sea topography, and atmospheric circulation, coastal areas often have natural winds that last for a long time and have a large average wind force. However, the fan 21 in the existing solution can only operate at a single wind speed and cannot dynamically adjust the wind speed according to the strength of the external natural wind. The fan 21 still maintains a fixed wind speed, which can easily lead to energy waste. The controller 41 is connected to the smart grid system. When the smart grid experiences peak electricity demand, power shortages, or high electricity prices, it will send a "demand response signal" to the controller 41 in the distribution cabinet. After receiving the signal, the controller 41 will dynamically adjust its internal temperature control strategy. Under this new strategy, the controller 41 will reduce the number of times the fan 21 is started or reduce its speed. In scenarios with weak external wind, fan 21 operates in normal cooling mode. The electrical components inside cabinet 1 generate heat during operation. Driven by fan 21, the hot air inside cabinet 1 is quickly exhausted from the side wall heat dissipation vent 5, while the cold air from the outside simultaneously enters cabinet 1 through the other side heat dissipation vent 5, forming an efficient air convection circulation to ensure that the internal temperature of cabinet 1 is stably maintained within the range suitable for the operation of electrical components. Initially, pressure sensor 44 is squeezed by rod 42 and square rod 43, causing pressure sensor 44 to generate a pressure signal. When wind detection component 3 detects strong winds in the external environment of cabinet 1, it controls the movement of square rod 43 according to the wind force. That is, the smaller the wind force, the smaller the movement of square rod 43, and vice versa. The movement of square rod 43 drives pressure sensor 44 to move synchronously away from rod 42, reducing the squeezing force on pressure sensor 44. The pressure signal output by pressure sensor 44 decreases as the movement (i.e., wind force) increases, and the real-time pressure signal is transmitted to controller 41. Controller 41 presets the pressure signal level classification rules. Different levels correspond to different fan 21 speed strategies. The stronger the external wind force, the lower the fan 21 speed is adjusted by controller 41. The weaker the external wind force, the higher the fan 21 speed is adjusted by controller 41. With the cooperation of wind detection component 3 and pressure sensor 44, the speed of fan 21 can be dynamically adjusted according to the strength of external natural wind, making maximum use of the abundant natural wind resources in coastal areas to assist in heat dissipation, and significantly reducing the ineffective energy consumption of fan 21 without changing the heat dissipation effect.

[0025] like Figure 4 and Figure 7 As shown, the adjustment assembly 4 also includes: a square shell 45 installed on the cabinet 1, a sliding plate 46 slidably installed inside the square shell 45, a thermal expansion material installed between the square shell 45 and the sliding plate 46, a first rod 42 fixedly installed on the sliding plate 46; and a spring installed between the first rod 42 and the square shell 45.

[0026] Specifically, the thermal expansion material can be thermal expansion resin or thermal expansion rubber, etc. The electrical components inside the cabinet 1 generate heat during operation. The thermal expansion material absorbs the heat and expands, pushing the slide plate 46 to move. The slide plate 46 drives the first rod 42 to move. Since the pressure sensor 44 is located between the square rod 43 and the first rod 42, the pressure sensor 44 will be squeezed when the temperature inside the cabinet 1 is higher, and will transmit the pressure signal to the controller 41. The controller 41 controls the fan 21 to start. As the internal temperature of the cabinet 1 increases, the pressure sensor 44 is squeezed more, which increases the pressure signal output by the pressure sensor 44. The controller 41 adjusts the wind speed of the fan 21 according to the preset pressure signal level. By using thermal expansion materials, pressure sensor 44 comprehensively senses two key parameters: the temperature inside cabinet 1 and the external wind force, and outputs a unified optimized control signal that characterizes the final heat dissipation requirements. Controller 41 adjusts the speed of fan 21 based on this signal to achieve on-demand heat dissipation.

[0027] like Figures 4-8As shown, the wind power detection component 3 includes: an impeller 31 rotatably mounted on the cabinet 1; a first circular shaft 32 rotatably mounted on the cabinet 1, on which a circular plate 33 is fixedly mounted; several push rods 34 slidably mounted on the circular plate 33, with springs installed between the push rods 34 and the circular plate 33; an arc-shaped plate 35 slidably mounted on the cabinet 1, within the range of motion of the push rods 34; and a drive structure 36 mounted on the cabinet 1, through which the movement of the arc-shaped plate 35 drives the square rod 43 to move.

[0028] like Figures 4-8 As shown, the drive structure 36 includes: a lead screw 361 that drives the square rod 43 to move, the lead screw 361 being rotatably mounted on the cabinet 1, and the square rod 43 being threadedly connected to the lead screw 361; a worm gear 362 that drives the lead screw 361 to rotate, the worm gear 362 being fixedly mounted on the lead screw 361; a worm gear 363 that drives the worm gear 362 to rotate; a first round rod 364 that is rotatably mounted on the cabinet 1, the worm gear 363 being fixedly mounted on the first round rod 364, and a gear 365 that is fixedly mounted on the first round rod 364; and a rack plate 366 that drives the gear 365 to rotate, the rack plate 366 being fixedly mounted on the arc plate 35.

[0029] Specifically, the first circular shaft 32 and the impeller 31 contain magnets, and the worm gear 362 and worm 363 have reverse self-locking capabilities to ensure that after the square rod 43 moves to the target position, it can maintain its position even if it loses power and will not be displaced in the opposite direction due to the squeezing of the first rod 42. The arc plate 35 and the push rod 34 are made of magnetic material so that when the push rod 34 is reset by the spring force, the arc plate 35 is reset synchronously. The number of push rods 34 must be such that there is always a push rod 34 in contact with the arc plate 35 when it rotates. When a strong wind is generated in the same direction as the two heat dissipation vents 5, it will cause the impeller 31 to rotate. The impeller 31 drives the first circular shaft 32 to rotate synchronously through magnetic force. The rotation of the first circular shaft 32 causes the circular plate 33 and the push rod 34 to rotate synchronously. Under the action of centrifugal force, the push rod 34 can slide radially along the circular plate 33 (the stronger the wind, the faster the rotation speed of the circular plate 33, and the greater the displacement of the push rod 34 relative to the circular plate 33). The sliding of the push rod 34 can push the arc plate 35 to slide. The arc plate 35 drives the rack plate 366 to move. The rack plate 366 and the gear 365 mesh, so the gear 365 rotates, driving the first circular rod 364 and the worm gear 363 to rotate synchronously. The worm gear 363 drives the worm wheel 362 to rotate. The worm wheel 362 drives the square rod 43 to move away from the first rod 42 through the lead screw 361, so as to reduce the pressure signal value of the pressure sensor 44.

[0030] As shown in the figure, the travel distance of the square rod 43 is less than that of the sliding plate 46.

[0031] Specifically, since the travel distance of the square rod 43 is less than that of the sliding plate 46, even if a strong wind is generated when the temperature inside the cabinet 1 is high, the pressure sensor 44 will generate a pressure signal, which means that the fan 21 will also work.

[0032] like Figure 2 and Figure 3 As shown, the heat dissipation assembly 2 also includes: two filters 22 installed on the cabinet 1; a second circular shaft 23 rotatably installed on the cabinet 1; and two connecting plates 24 symmetrically fixed on the fan 21, with the second circular shaft 23 connected to the connecting plates 24.

[0033] Specifically, the filter 22 is used to filter dust in the air. During operation, the fan 21 at one of the heat dissipation vents 5 is responsible for introducing external air into the cabinet 1, while the fan 21 at the other heat dissipation vent 5 is responsible for expelling the air inside the cabinet 1 outward, thus forming an air circulation inside the cabinet 1. When a strong wind is generated outside that is in the same direction as the two heat dissipation vents 5, the second circular shaft 23 can be rotated according to the actual wind direction. When the second circular shaft 23 rotates, it will drive the connecting plate 24 to rotate synchronously, and the two fans 21 connected to the connecting plate 24 will also rotate synchronously. On the one hand, this ensures that the airflow inside the cabinet 1 is always synchronized with the external wind direction, avoiding interference from the external strong wind on the airflow circulation inside the cabinet 1, and also helps with heat dissipation. On the other hand, the rotation of the fan 21 will change the wind direction acting on the filter 22. This change in wind direction can blow away the dust accumulated on the filter 22, thereby helping the filter 22 to stay clean and maintain its filtering performance.

[0034] like Figures 4-10 As shown, the adjustment assembly 4 also includes: a baffle 47 fixedly installed on the arc plate 35; a connecting block 48 and a limiting plate 49, wherein the limiting plate 49 is rotatably connected to the connecting block 48, and a torsion spring is installed between the limiting plate 49 and the connecting block 48; two second round rods 410 rotatably installed on the cabinet 1, wherein the second round rods 410 are provided with a sliding groove 411, and the connecting block 48 has a protrusion that is slidably connected to the sliding groove 411; and a delay structure 412 for driving the second round rods 410 to rotate.

[0035] like Figures 4-10 As shown, the delay structure 412 includes: a second gear 4121 fixedly mounted on the second round rod 410; a third gear 4122 fixedly mounted on the first round shaft 32; a gear set 4123 rotatably mounted on the cabinet 1, the third gear 4122 intermittently driving the second gear 4121 to rotate through the gear set 4123; and a third spring installed between the connecting block 48 and the second round rod 410.

[0036] Specifically, when the arc plate 35 approaches the circular plate 33, it can push the limiting plate 49 to rotate through the baffle 47. Otherwise, the limiting plate 49 cannot rotate. The gear set 4123 includes several complete gears and incomplete gears. Gear 2 4121 and gear 3 4122 are incomplete gears. That is, after the gear set 4123 drives it to rotate a certain angle, even if the gear set 4123 continues to rotate, it can stop rotating. The sliding groove 411 on the second circular rod 410 is inverted V-shaped so that even if the impeller 31 rotates in different directions and the second circular rod 410 rotates in different directions, the rotation of the second circular rod 410 can drive the connecting block 48 to move downward. When the first circular shaft 32 rotates, it drives the third gear 4122 to rotate synchronously. The third gear 4122 drives the second gear 4121 to rotate intermittently through the gear set 4123. The rotation of the second gear 4121 drives the second circular rod 410 to rotate synchronously, which in turn drives the connecting block 48 and the limiting plate 49 to move downward. Since the third gear 4122 drives the second gear 4121 to rotate intermittently through the gear set 4123, the connecting block 48 and the limiting plate 49 can only complete the downward movement after the strong wind has been blowing for a period of time. After the connecting block 48 and the limiting plate 49 move downward, the arc plate 35 is no longer blocked by the limiting plate 49. At this time, it can slide under the push of the push rod 34 and drive the square rod 43 to move through the drive structure 36, so that the pressure signal of the pressure sensor 44 changes, and finally realizes the adjustment of the wind speed of the fan 21. By setting the delay structure 412, occasional short-term gusts and turbulence in coastal areas are filtered out, avoiding accidental sliding of the arc plate 35 and accidental movement of the square rod 43 due to instantaneous wind fluctuations. This prevents frequent changes in pressure signals from causing repeated adjustments to the fan speed 21, ensuring that the fan speed adjustment is only for continuous and effective natural wind. This avoids ineffective energy consumption fluctuations and ensures stable temperature inside the cabinet 1, preventing fluctuating heat dissipation efficiency due to frequent switching of fan speed.

[0037] like Figure 4 and Figure 5 As shown, the wind detection component 3 also includes: a wind-catching plate 313 slidably mounted on the cabinet 1; a T-shaped rod 314 rotatably mounted on the cabinet 1, on which two sensors 315 are mounted, and the two sensors 315 are electrically connected to the controller 41; and a ring 316 slidably mounted on the cabinet 1, which is threadedly connected to the T-shaped rod 314.

[0038] Specifically, sensor 315 and T-shaped rod 314 are connected by a spring-controlled telescopic rod. The wind-catching plate 313 and ring 316 contain magnets for driving movement. When a strong wind is generated in the same direction as the two heat dissipation vents 5, the wind blows the wind-catching plate 313 to slide in the corresponding direction (left or right). The wind-catching plate 313 pushes the ring 316 to slide synchronously through the magnetic field. Since the ring 316 and T-shaped rod 314 are threadedly connected, the sliding of the ring 316 will cause the T-shaped rod 314 to rotate, causing the positions of the two sensors 315 to be interchanged. After the strong wind continues for a period of time, the arc-shaped... After unlocking, the board 35 moves and comes into contact with the adjusted sensor 315. When the sensor 315 is triggered, it transmits a signal to the controller 41. The controller 41 identifies the triggered sensor 315, accurately determines the specific direction of the current natural wind, and analyzes whether the natural wind can enhance the air circulation in the cabinet 1 in combination with the preset air convection direction in the cabinet 1. If the wind direction is consistent with the air flow direction in the cabinet 1, the controller 41 maintains the original rotation of the fan 21 to improve the heat dissipation efficiency with the help of the natural wind. If the wind direction is opposite, the controller 41 immediately controls the fan 21 to rotate in the opposite direction to adjust the air flow direction in the cabinet 1.

[0039] like Figure 3 As shown, the heat dissipation assembly 2 also includes: a socket formed on the connecting plate 24; and several electrically operated telescopic rods 25 for positioning the connecting plate 24 by inserting into the socket.

[0040] Specifically, the rotating connecting plate 24 and fan 21 can be positioned by means of the socket and the electric telescopic rod 25.

[0041] Working principle: The electrical components inside cabinet 1 generate heat during operation. The thermal expansion material absorbs the heat and expands, pushing the slide plate 46 to move. The slide plate 46 then moves the first rod 42. Since the pressure sensor 44 is located between the square rod 43 and the first rod 42, the pressure sensor 44 will be compressed when the temperature inside cabinet 1 is higher, and will transmit the pressure signal to the controller 41. The controller 41 controls the fan 21 to start. Through the active drive of the fan 21, the hot air inside cabinet 1 is quickly discharged from the heat dissipation vent 5 on the side wall, and the cold air from the outside enters cabinet 1 through the heat dissipation vent 5 on the other side, forming an efficient air convection circulation. This ensures that the internal temperature of cabinet 1 is maintained stably within the range suitable for the operation of the electrical components. As the internal temperature of cabinet 1 increases, the pressure sensor 44 is subjected to increased pressure, which increases the pressure signal output by the sensor. The controller 41 adjusts the fan speed of the fan 21 according to the preset pressure signal level. When a strong wind is generated in the same direction as the two heat dissipation vents 5, it will cause the impeller 31 to rotate. The impeller 31 drives the first circular shaft 32 to rotate synchronously through magnetic force. When the first circular shaft 32 rotates, it drives the third gear 4122 to rotate synchronously. The third gear 4122 drives the second gear 4121 to rotate intermittently through the gear set 4123. The rotation of the second gear 4121 drives the second circular rod 410 to rotate synchronously, which in turn drives the connecting block 48 and the limiting plate 49 to move downward. Since the third gear 4122 is connected to the gear set 4123... The gear 4121 is driven to rotate intermittently. Therefore, the connecting block 48 and the limiting plate 49 can only move downward after the strong wind has been blowing for a period of time. After the connecting block 48 and the limiting plate 49 move downward, the arc plate 35 is no longer blocked by the limiting plate 49. The first circular shaft 32 rotates simultaneously, causing the circular plate 33 and the push rod 34 to rotate synchronously. Under the action of centrifugal force, the push rod 34 can slide radially along the circular plate 33 (the stronger the wind, the faster the circular plate 33 rotates, and the more the push rod 34 generates relative to the circular plate 33). The greater the displacement, the greater the displacement. When the arc plate 35 is restricted, the push rod 34 can generate displacement when it is not in contact with the arc plate 35. After contacting the arc plate 35, the push rod 34 is reset by the curvature of the arc plate 35 wall. After the arc plate 35 is restricted, the push rod 34 can push the arc plate 35 to slide. The arc plate 35 drives the rack plate 366 to move. The rack plate 366 and gear 365 mesh, so gear 365 rotates, driving the first round rod 364 and the worm gear 363 to rotate synchronously. The worm gear 363 drives... The worm gear 362 rotates, and the worm gear 362 drives the square rod 43 to move away from the first rod 42 through the lead screw 361, reducing the squeezing force on the pressure sensor 44. This causes the pressure signal output by the pressure sensor 44 to decrease as the amount of movement (i.e., the wind force) increases, and the real-time pressure signal is transmitted to the controller 41. The controller 41 adjusts the speed of the fan 21 to maximize the use of the abundant natural wind resources in the coastal area to assist in heat dissipation. Under the condition that the heat dissipation effect remains unchanged, the ineffective energy consumption of the fan 21 is significantly reduced. When a strong wind is generated in the same direction as the two heat dissipation vents 5, the wind blows the wind-catching plate 313 to slide in the corresponding direction (left or right). The wind-catching plate 313 pushes the ring 316 to slide synchronously through the magnetic field force. Since the ring 316 and the T-shaped rod 314 are threadedly connected, the sliding of the ring 316 will drive the T-shaped rod 314 to rotate, causing the positions of the two sensors 315 to be reversed. After the strong wind continues for a period of time, the arc plate 35 moves after unlocking and contacts the adjusted sensor 315. Once triggered, sensor 315 transmits a signal to controller 41. Controller 41 identifies the triggered sensor 315, accurately determines the current direction of the natural wind, and analyzes whether the natural wind can enhance the air circulation inside cabinet 1 in conjunction with the preset air convection direction inside cabinet 1. If the wind direction is consistent with the air flow direction inside cabinet 1, controller 41 maintains the original rotation of fan 21 to improve heat dissipation efficiency with the help of natural wind. If the wind direction is opposite, controller 41 immediately controls fan 21 to rotate in the opposite direction to adjust the air flow direction inside cabinet 1.
