Description

Technical Field

[0001] The present invention relates to electrical technical equipment, and in particular to an air outlet device, a control method and an energy storage container. Background Art

[0002] With the increasing application of containerized electrochemical energy storage systems, energy storage containers are becoming more and more widely distributed across various regions. One side of the energy storage container is usually equipped with an air-cooled or liquid-cooled air conditioner to regulate the internal temperature of the container. Existing energy storage container air conditioner inlets and outlets are usually designed with diamond-shaped grilles. These grilles are simple to manufacture, requiring only a dense hole die to punch holes on the front of the air conditioner. However, in dusty weather conditions, the diamond-shaped grilles cannot effectively protect against dust. Dust from the outside may enter the air conditioner, causing dust accumulation, blocking the condenser, and even blocking the fan.

[0003] To address this issue, existing technologies employ rotating blades at the air outlet of air conditioners. In windy and dusty environments, the blades close to prevent dust from entering the air conditioner. However, these blades require manual operation to open and close. During the transportation of energy storage containers, drivers cannot manually open and close the blades based on environmental changes while driving, which can compromise road safety. Furthermore, energy storage containers are often deployed outdoors as mobile energy stations, and manually opening and closing the blades based on environmental changes can result in significant labor costs.

[0046] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the scope of protection of the present invention is not limited to the specific embodiments described below.

[0047] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediate medium; they may refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0048] In the description of the present invention, some directional words are involved to clearly illustrate the technical solution of the present invention. For example, "up" and "down" are the meanings of the directions normally referred to during the operation of the air outlet device by analogy. "Outside" refers to the area in contact with the external environment when the air outlet device is working, and "inside" refers to the area located in the internal space of the energy storage container when the air outlet device is working. It should be understood that the directional terms are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the present invention.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0050] It should be noted in advance that in order to facilitate understanding of the technical solution of the present invention, in the following description, a rectangular plane is cut out from the outer surface of the circular shaft, and the plane is called the "flat position", and the shaft is called the "flat position shaft"; the "flat position hole" is the hole that matches the flat position shaft.

[0051] refer to Figures 2 to 6The present invention provides an air outlet device, comprising a drive device 1. The drive device 1 is connected to at least one blade 4 via a connector. The connector may include an active rod 2 and a fixed rod 3 connected to the drive device 1. A plurality of longitudinally arranged blades 4 are rotatably connected between the active rod 2 and the fixed rod 3. Each blade 4 is provided with a pressure sensor 5. The pressure sensor 5 may be provided on each blade 4, spaced apart on each blade 4, or provided only on one blade 4. The specific location and number of pressure sensors 5 may be determined based on actual needs and usage. The drive device 1 and the pressure sensor 5 are both electrically connected to a control unit, which controls the drive device 1 to adjust the rotation angle of the blade 4 based on signals from the pressure sensor 5. Specifically, when the air outlet device is in operation, the control unit controls the drive device 1 to operate, causing the blade 4 to open and define a recessed portion opening upward. The pressure sensor 5 is located within the recessed portion to detect the weight of dust accumulated in the recessed portion. The control unit determines the relationship between the pressure value transmitted by the pressure sensor 5 and a set pressure threshold, and based on the determination, controls the drive device 1 to rotate the blade 4 to a set operating angle. The drive device 1 includes, but is not limited to, a stepper motor, a servo motor, a pneumatic motor, a hydraulic motor, and the like. A single drive device 1 can be configured to control the rotation of multiple blades 4 via the active rod 2. Alternatively, multiple drive devices 1 can be configured to each drive a blade 4, allowing each blade 4 to be adjusted to a different angle. This is primarily due to the varying sand density distribution in a sandstorm. By reducing the opening angle of blades 4 in areas with high sand density and increasing it in areas with low sand density, the area of the air outlet device's inlet / outlet can be maintained within an appropriate range. In the above description, "longitudinal" refers to the length of the active rod 2 and the fixed rod 3.

[0052] In some embodiments, reference Figure 7The driving mechanism also includes a flat shaft sleeve 6, which includes a flat position hole 61 and a round shaft buckle 62. The round shaft buckle 62 is formed into a symmetrical or approximately symmetrical structure with an opening, and the width and depth of the opening can be designed according to actual needs. A clamping portion is formed at the end of the round shaft buckle 62, and the bottom diameter of the clamping portion is larger than the main body diameter of the round shaft buckle 62, so that when the round shaft buckle 62 is clamped with the hole, the clamping portion can limit the displacement of the flat shaft sleeve 6 in all directions in a natural state. The output shaft of the driving device 1 is a flat position shaft, which is suitable for being inserted into the flat position hole 61 of the flat shaft sleeve 6, and the flat position on the output shaft and the flat position hole 61 of the flat shaft sleeve 6 are fixed to each other, and the round shaft buckle 62 of the flat shaft sleeve 6 is suitable for being inserted into the mounting hole of the active rod 2, and can be freely rotated in the mounting hole. The blade 4 has a flat shaft so that it can cooperate and be fixed with the flat hole 61 of the flat shaft sleeve 6, and the round shaft buckle 62 of the flat shaft sleeve 6 is connected to the mounting hole on the active rod 2. The driving device 1 can drive the flat shaft sleeve 6 connected to the output shaft to rotate, and then drive the active rod 2 connected to the flat shaft sleeve 6 to move, and the movement direction of the active rod 2 is the tangent direction of the rotation trajectory circle of the end where the round shaft buckle 62 of the flat shaft sleeve 6 connected to the driving device 1 is located. The active rod 2 can drive the blade 4 connected to the active rod 2 through the flat shaft sleeve 6 to rotate.

[0053] In some embodiments, the active rod 2 is provided with multiple first mounting holes 21 along its length, and the circular shaft buckles 62 are adapted to engage with the first mounting holes 21. The centers of the multiple first mounting holes 21 are all coaxial, and the centers of the circular shaft buckles 62 that engage the first mounting holes 21 are also coaxial. When the drive device 1 drives the active rod 2, the flat shaft sleeve 6 and the blades 4 are mutually restrained by the flat position, allowing the active rod 2 to synchronously rotate the blades 4 connected to the active rod 2 via the flat shaft sleeve 6. Furthermore, the number of first mounting holes 21 can be selected based on actual usage requirements.

[0054] In some embodiments, a plurality of second mounting holes are provided along the length of the fixed rod 3, and the number of the second mounting holes corresponds to the number of blades 4. A circular shaft sleeve 7 is inserted into the second mounting holes and connected to the blades 4. A flat shaft is formed at one end of the blade 4 and connected to the active rod 2 via a flat shaft sleeve 6. A circular shaft is formed at the other end and connected to the fixed rod 3 via a circular shaft sleeve 7. The circular shaft sleeve 7 is adapted to be inserted into and fixed to the second mounting hole. The circular shaft on the blade 4 can rotate freely within the circular shaft sleeve 7. The centers of the plurality of second mounting holes are located on the same axis, and the plurality of first mounting holes 21 on the active rod 2 for connecting to the blades 4 are provided corresponding to the second mounting holes.

[0055] In addition, as another embodiment of the air outlet device of the present invention, the air outlet device may further include a fixed frame, a plurality of blades 4 are placed in the area surrounded by the fixed frame, a first vertical frame of the fixed frame close to the driving device 1 side is arranged parallel to the active rod 2, a plurality of through holes are opened in the length direction of the first vertical frame, the end where the flat hole 61 of the flat shaft sleeve 6 is located has a limiting portion extending in the opposite direction to the round shaft buckle 62, the limiting portion is suitable for being snapped into the through hole on the first vertical frame, and the round shaft buckle 62 is suitable for being snapped into the first mounting hole 21 on the active rod 2, thereby completing the installation of the active rod 2 and the fixed frame. The second vertical frame on the fixed frame opposite to the first vertical frame can be directly used as the fixed rod 3. In the above description, "vertical" refers to the direction perpendicular to the ground when the air outlet device is working normally.

[0056] In some embodiments, reference Figures 4 to 6 , the cross section of the blade 4 is formed into a "2" shape; or refer to Figure 8 , the cross section of the blade 4 is formed into an "S" shape; or refer to Figure 9 The cross section of the blade 4 is formed into a "Z" shape. The specific structure of the blade 4 can be selected according to actual use requirements.

[0057] In some embodiments, reference Figure 6 , the blade 4 includes a first baffle 41, a second baffle 42, a third baffle 43, a fourth baffle 44 and a fifth baffle 45 connected in sequence. The first baffle 41 and the second baffle 42 can overlap with the fifth baffle 45 and the fourth baffle 44 respectively after rotating 180 degrees around the center of the third baffle 43. When the interconnected parts of the first baffle 41, the second baffle 42, the third baffle 43, the fourth baffle 44 and the fifth baffle 45 do not transition in a circular arc or transition in a smaller circular arc, the cross section of the blade 4 is formed into a "2" shape. When the interconnected parts of the first baffle 41, the second baffle 42, the third baffle 43, the fourth baffle 44 and the fifth baffle 45 transition in a larger circular arc, the cross section of the blade 4 is formed into an "S" shape. The blade 4 can also be integrally formed into a structure with a "2"-shaped cross section or an "S"-shaped cross section. Figure 5 、 Figure 6 and Figure 8 The orientation of the air outlet device is used as a reference. The opening formed by the interconnection of the first baffle 41, the second baffle 42 and the third baffle 43 faces the outside of the air outlet device, and the opening formed by the interconnection of the third baffle 43, the fourth baffle 44 and the fifth baffle 45 faces the inside of the air outlet device. Figure 5 and Figure 8As shown, the tail end of the previous blade 4 and the top end of the next blade 4 are inserted into each other, forming a maze structure. That is, the first baffle 41 of blade 4 is located above the fifth baffle 45 of the adjacent blade 4, and the fifth baffle 45 of blade 4 is located below the first baffle 41 of the adjacent blade 4. As a result, dust from the external environment has difficulty entering the internal space of the air outlet device, and a gap is left between the first baffle 41 and the fifth baffle 45 of the adjacent blade 4 to prevent mutual interference between the blades 4 during rotation. In the above description, "external" refers to the area of the air outlet device that comes into contact with the external environment during operation, and "inside" refers to the area of the air outlet device that does not come into contact with the external environment during operation.

[0058] In some embodiments, there is a gap between adjacent blades 4, that is, the gap between the first baffle 41 and the fifth baffle 45 of the adjacent blade 4, refer to Figure 10 A sealing strip 8 may be provided on the surface of the first baffle 41 facing the fifth baffle 45 and / or on the surface of the fifth baffle 45 facing the first baffle 41 to eliminate or reduce vertical gaps between adjacent blades 4. When the blades 4 of the air outlet device are closed, the sealing strip 8 on the first baffle 41 of the blade 4 presses against the sealing strip 8 on the fifth baffle 45 of the adjacent blade 4 or against the inner surface of the fifth baffle 45, forming a seal; or the sealing strip 8 on the fifth baffle 45 of the blade 4 presses against the inner surface of the first baffle 41 of the adjacent blade 4, forming a seal. There are also left and right gaps between adjacent blades 4, i.e., there is a gap between the end face of the first baffle 41 and the inner surface of the fourth baffle 44 of the adjacent blade 4, and there is a gap between the fifth baffle 45 and the inner surface of the second baffle 42 of the adjacent blade 4. To further improve the dust and sand blocking capability of the blades 4 when they are closed, sealing strips can be provided at the end faces of the first baffle 41 and the fifth baffle 45, or the end lengths of the first baffle 41 and the fifth baffle 45 can be extended. The blades 4 can also be driven to close by the driving device 1. When the adjacent blades 4 abut against each other, the blades 4 continue to be driven to rotate. At this time, the rotation process will encounter resistance. When the resistance exceeds a certain value, the driving device 1 stops rotating, thereby achieving sealing of the left and right gaps between adjacent blades 4. Through the above embodiment, double sealing between adjacent blades 4 can be achieved, thereby further enhancing the ability of the air outlet device to block external wind, sand and rainwater when not in operation.

[0059] In some embodiments, the included angle α between the second baffle 42 and the third baffle 43 is ≥100°, so that the dust or rainwater falling on the surface of the blade 4 can naturally slide down along the inclined surface of the third baffle 43 under the action of gravity and cannot accumulate on the surface of the blade 4.

[0060] In addition, as another embodiment of the blade 4 of the present invention, refer to Figure 9The blade 4 includes a second baffle 42, a third baffle 43, and a fourth baffle 44. The second baffle 42, the third baffle 43, and the fourth baffle 44 are interconnected to form a blade structure with a "Z" cross-section. The opening formed by the interconnection of the second and third baffles 42, 43 faces the exterior of the air outlet device, while the opening formed by the interconnection of the third and fourth baffles 43, 44 faces the interior of the air outlet device. A sealing strip 8 may be provided on the surface of the second baffle 42 that faces the fourth baffle 44 of the adjacent blade 4, and / or on the surface of the fourth baffle 44 that faces the second baffle 42 of the adjacent blade 4 to reduce or eliminate vertical gaps between adjacent blades 4. Seals may also be provided at the ends of the second and fourth baffles 42, 44, or the lengths of the second and fourth baffles 42, 44 may be extended. Alternatively, when the blades 4 are closed, adjacent blades 4 may abut against each other and achieve a certain resistance. This reduces or eliminates horizontal gaps between adjacent blades 4, thereby improving the blades' ability to block wind and sand. The included angle θ between the second baffle 42 and the third baffle 43 is ≤80°. When the blade 4 is in the closed state, dust or rainwater falling on the surface of the blade 4 can slide down along the outer surface of the third baffle 43 under the action of gravity.

[0061] In the above embodiments of each blade 4, a flattening shaft 46 is provided at the center of the third baffle 43. The flattening shaft 46 is adapted to be fixedly engaged with the flattening hole 61 of the flattening sleeve 6. The flattening shaft 46 is provided at a symmetrical point in the center of the blade 4, thereby maintaining dynamic balance during the rotation of the blade 4.

[0062] In some embodiments, see Figure 5 、 Figure 6 and Figure 9 , the pressure sensor 5 is located at the connection between the second baffle 42 and the third baffle 43. When the air outlet device is in working state, such as Figure 6 As shown, the blade 4 is opened, and the angle area formed by the second baffle 42 and the third baffle 43 is likely to form a "sand gathering area". Therefore, the pressure sensor 5 is arranged in this angle area, which can effectively detect the amount of sand and dust accumulated on the blade 4, thereby being able to judge the situation of the external environment.

[0063] The second aspect of the present invention provides a method for controlling an air outlet device, referring to Figure 11, comprising the aforementioned air outlet device and the following steps: acquiring data from the pressure sensor 5; determining whether the data from the pressure sensor 5 is within an operating threshold range, and adjusting the rotation angle of the blades 4 based on the determination result. Specifically, the pressure sensor 5 collects the dust weight G that has fallen on the blades 4 every time period T and transmits this dust weight G information to a control unit. The control unit has preset dust weight thresholds G1 and G2. The control unit determines whether the dust weight G is within either of these thresholds and, based on the determination result, controls the rotation of the drive device 1, thereby driving the blades 4 to rotate to the angle corresponding to the determination result.

[0064] Specifically, it is determined whether the data of the pressure sensor 5 is within the working threshold range, and the rotation angle of the blade 4 is adjusted based on the determination result, including: when the data of the pressure sensor 5 is within the first working threshold range, the opening angle of the blade 4 is adjusted to β; or when the data of the pressure sensor 5 is within the first working threshold and the second working threshold range, the opening angle of the blade 4 is adjusted to 0, and after a preset time T1, the opening angle of the blade 4 is adjusted to β / 2; or when the data of the pressure sensor 5 exceeds the second working threshold, the opening angle of the blade 4 is adjusted to 0, and the air outlet device alarms and pushes the alarm information to the user terminal to remind the user whether to continue running the air outlet device. The above data of the pressure sensor 5 is the weight G of the dust accumulated on the blade 4, the first working threshold is the critical value G1 of the dust weight preset in the control unit, and the second working threshold is the critical value G2 of the dust weight preset in the control unit. Then, within the time period T, when G < G1, it indicates that the dust content in the external environment is low, and the air outlet device can work normally. The control unit controls the driving device 1 to rotate so that the opening angle of the blade 4 is β; when G1 ≤ G ≤ G2, it indicates that the dust content in the external environment is medium or the amount of dust accumulated on the blade 4 is large, and there is a risk that the dust enters the interior of the air outlet device. The control unit controls the driving device 1 to rotate so that the blade 4 is completely closed. At this time, the dust accumulated on the blade 4 can slide down under the action of gravity, and the blade 4 is kept in the closed state. After a time period T1, the control unit controls the driving device 1 to rotate so that the opening angle of the blade 4 is β / 2, reducing the windward area of the blade 4, thereby effectively reducing the amount of dust entering the interior of the air outlet device from the external environment; when G > G2, it indicates that the dust content in the external environment is high, and it may have entered the sandstorm stage. At this time, the control unit controls the driving device 1 to rotate so that the blade 4 is completely closed, that is, the opening angle of the blade 4 is 0, and an alarm can be given through the alarm. The alarm prompt includes but is not limited to lighting or beeping. The control unit can also push the alarm information to the user's mobile phone user terminal or computer terminal for reminder, and whether to continue running the air outlet device is manually intervened. When the air outlet device is initially started to work, the initial opening angle of the blade 4 is β, and β ≤ 90°. The size of the initial opening angle β of the blade 4 can be controlled by obtaining the weather information of the location where the air outlet device is located. Exemplarily, if the weather information obtained at the location where the air outlet device is located is that the current weather dust is relatively severe, the initial opening angle β of the blade 4 can be controlled to be 60°, or if the weather information obtained at the location where the air outlet device is located is normal (sunny, cloudy, overcast, etc.), the initial opening angle β of the blade 4 can be controlled to be 90°.

[0065] Specifically, the air outlet device alarms and pushes the alarm information to the user terminal to remind the user whether to continue running the air outlet device, including: when the user turns on the air outlet device, the control unit controls the driving device 1 to rotate so that the opening angle of the blade 4 is β / 2. Every time a time period T’ passes, the control unit obtains the weight G of the dust accumulated on the current blade 4 collected by the pressure sensor 5, and judges whether the dust weight G exceeds the set threshold G3; if the dust weight G does not exceed the set threshold G3, the control unit controls the driving device 1 to rotate so that the opening angle of the blade 4 is β / 2; or if the dust weight G exceeds the set threshold G3, the control unit controls the driving device 1 to rotate so that the opening angle of the blade 4 is 0, and keeps the blade 4 in the closed state. After a time period T2, the control unit controls the driving device 1 to rotate so that the opening angle of the blade 4 is β / 2. Further, when the dust weight G detected after two or more time periods T’ is less than the set threshold G3, it can return to the judgment loop at the initial operation of the air outlet device, that is, every time a time period T passes, the dust weight G on the blade 4 is collected, and the dust weight G is compared with the preset dust weight critical value G1 and the dust weight critical value G2 for judgment, and the opening angle of the blade 4 is adjusted based on the judgment result. In addition, the user can also set multiple dust weight critical values according to actual usage requirements to achieve more angle adjustment of the blade 4. Exemplarily, the dust weight critical value G1, the dust weight critical value G2 and the dust weight critical value G4 are set. When the dust weight G collected by the pressure sensor 5 satisfies G2 < G < G4, the opening angle of the blade 4 is adjusted to β / 4.

[0066] The third aspect of the present invention provides an energy storage container, which includes an air conditioner, the above-mentioned air outlet device for the air conditioner, and the control method of the air outlet device. Refer to Figure 1The energy storage container includes a sheet metal panel 9, which is provided with a plurality of openings for installing a plurality of air outlet devices. The specific size of the air outlet device and the installation position on the sheet metal panel 9 can be selected according to actual use requirements. A fixing frame is provided around the above-mentioned opening, and a plurality of through holes are provided on the first vertical frame frame close to the fixing frame on the side of the drive device 1 and the second vertical frame frame opposite to the first vertical frame frame. During assembly, the drive device 1 is provided with mounting ears, and the drive device 1 can be fixed to the sheet metal panel 9 by screws to complete the installation of the drive device 1. The output shaft of the drive device 1 has a flat position, and the output shaft and the flat position hole 61 on the flat shaft sleeve 6 are matched and fixed to each other, and the round shaft buckle 62 on the flat shaft sleeve 6 is buckled into the corresponding first mounting hole 21 on the active rod 2 to complete the installation of the drive device 1 and the active rod 2. Then, the same number of flat shaft sleeves 6 as the blades 4 can be inserted into the through holes of the first vertical frame, and the same number of round shaft sleeves 7 as the blades 4 can be inserted into the through holes of the second vertical frame. Both the flat shaft sleeves 6 and the round shaft sleeves 7 are provided with a limit portion to prevent the flat shaft sleeves 6 and the round shaft sleeves 7 from falling out of the through holes of the first vertical frame or the second vertical frame. The blade 4 has a flat shaft 46 at one end close to the drive device 1 and a round shaft at the other end. After the flat shaft sleeves 6 and the round shaft sleeves 7 are installed with the fixed frame, the two end shafts of the blade 4 can be inserted into the corresponding shaft sleeves in turn, that is, the flat shaft 46 of the blade 4 is inserted into the flat shaft sleeve 6, and the round shaft of the blade 4 is inserted into the round shaft sleeve 7 to complete the installation of the blade 4. The active rod 2 is provided with the same number of first mounting holes 21 as the flat shaft sleeves 6. The round shaft buckle 62 on the flat shaft sleeve 6 is buckled into the corresponding first mounting hole 21 on the active rod 2 to complete the installation of the air outlet device.

[0067] As a specific embodiment of the present invention, the air outlet device includes a driving mechanism and a control unit. The driving mechanism includes a fixed frame, a driving device 1, an active rod 2, a flat shaft sleeve 6 and a round shaft sleeve 7. The driving device 1 is connected to the active rod 2 through the flat shaft sleeve 6. One end of the flat shaft sleeve 6 for connecting to the blade 4 is connected to the active rod 2, and the other end is connected to the fixed frame. A plurality of blades 4 are provided in the area enclosed by the fixed frame. A flat shaft 46 is formed at one end of the blade 4 close to the driving device 1 side, and a round shaft is formed at the other end. The flat shaft 46 is suitable for being inserted into the corresponding flat shaft sleeve 6, so that the blade 4 is connected to the active rod 2 through the flat shaft sleeve 6, and the round shaft is suitable for being inserted into the corresponding round shaft sleeve 7, so that the blade 4 is connected to the fixed frame through the round shaft sleeve 7. The blade 4 includes a first baffle 41, a second baffle 42, a third baffle 43, a fourth baffle 44 and a fifth baffle 45 connected in sequence, and its cross-section is "2"-shaped. The tail ends and top ends of adjacent blades 4 are inserted into each other to form a maze structure. The angle α between the second baffle 42 and the third baffle 43 is 100°, and a pressure sensor 5 is provided at the connection between the second baffle 42 and the third baffle 43. The pressure sensor 5 and the drive device 1 are both electrically connected to the control unit.

[0068] Based on the specific implementation of the above-mentioned air outlet device, the air outlet device is applied to the air conditioner of the energy storage container. When the air conditioner is turned off, the air outlet device is in a non-working state. Figure 5 As shown, the tail ends and top ends of adjacent blades 4 are inserted into each other to form a maze structure. Since the angle α between the second baffle 42 and the third baffle 43 of the blade is 100°, the dust or rain falling on the third baffle 43 can slide along the outer surface of the third baffle 43 under the action of gravity, effectively preventing the possibility of dust entering the air conditioner through the air outlet device. When the air conditioner is started and the air outlet device is in normal working condition, as shown in FIG. Figure 6 As shown, the blade 4 rotates clockwise to open, and the dust in the air is blocked by the first baffle 41 when passing through the blade 4 and will gather in this area. At this time, the angle area between the second baffle 42 and the third baffle 43 forms a "sand gathering area". The pressure sensor 5 is responsible for detecting and collecting the weight of the dust accumulated in the "sand gathering area". After each time period T, the dust weight information is transmitted to the control unit. The control unit determines the external sand-containing environment by comparing the dust weight with the set dust weight critical value. The control unit controls the operation of the drive device 1 based on the judgment result, so that the opening angle of the blade 4 is within the angle range corresponding to the judgment result. Specifically, refer to Figure 12 When the air conditioner starts, the control unit controls the output shaft of the drive unit 1 to rotate, causing the blades 4 to open. The pressure sensor 5 collects the dust weight G accumulated on the blades 4. When the dust weight G is less than the critical dust weight value G1, the air conditioner operates normally, and the opening angle of the blades 4 is β. When the critical dust weight value G1 is less than or equal to the critical dust weight value G2, the control unit controls the drive unit 1 to rotate, causing the blades 4 to close. After a time T, the control unit controls the drive unit 1 to rotate, causing the opening angle of the blades 4 to be β / 2. When the dust weight G is greater than the critical dust weight value G2, the control unit controls the drive unit 1 to rotate, causing the blades 4 to close. At this time, the air conditioner stops and an alarm sounds. The above-mentioned automatic control of the opening angle of the air outlet device blades 4 to cope with different external sand-containing environments effectively reduces the workload of workers and avoids the situation where, when the environment changes drastically, the air conditioner is not closed in time by the operator, resulting in a large amount of dust entering the air conditioner, thereby shortening its service life.
