Description

Technical Field

[0001] The present invention belongs to the technical field of server cabinet environment monitoring, and in particular relates to a server cabinet dust detection device and a detection method. Background Art

[0002] With the rapid development of information technology, the density of equipment in data centers and server rooms continues to increase, which not only increases the requirements for cooling systems, but also poses higher challenges to air filtration and dust management. As the main carrier for storing key IT equipment, the quality of the internal environment of the server cabinet directly affects the performance, reliability and service life of the equipment. However, in actual applications, the dust particles carried by the external air when entering the cabinet will gradually accumulate inside the cabinet, leading to problems such as overheating, electrical short circuits, and corrosion. Therefore, how to effectively control the dust content in the cabinet while ensuring good ventilation and heat dissipation has become a technical problem that needs to be solved urgently.

[0003] The application number is CN202323020948.7, which is a dust detection device for a communication cabinet, comprising a communication cabinet and a cabinet door hinged to the communication cabinet, wherein a detection mechanism with a top opening is installed inside the communication cabinet, and a light-emitting component and a light intensity detector are installed on the left and right inner walls of the detection mechanism, respectively, and a reflector is installed inside the detection mechanism, and a microcontroller is installed at the bottom of the detection mechanism. The dust detection device for the communication cabinet, by setting a light intensity detector, the light-emitting component will emit a beam of light to the microcontroller, and the light will be reflected by the microcontroller and then enter the light intensity detector, and the light intensity will be detected by the light intensity detector, and the detection result will be sent to the microcontroller. When the light intensity is lower than the preset threshold in the microcontroller, it means that there is a lot of dust accumulated inside the communication cabinet and it needs to be cleaned.

[0004] Another example is a smart cabinet microenvironment information collection device with application number: CN201922044391.8, which includes a smart cabinet body, a dust detection sensor is arranged on the back side of the inside of the smart cabinet body, the dust detection sensor is fixedly arranged on a fixed block, and an adjustment mechanism for adjusting the position height of the dust detection sensor is fixedly arranged on one side of the fixed block. The utility model detects the dust content in the smart cabinet body through the operation of the dust detection sensor, and displays the detected data through the dust detection controller. The maintenance personnel can clean the dust in the smart cabinet body in time according to the data obtained by the detection. The micro motor drives the screw to rotate, and the self-rotation of the screw can drive the movable block connected to the screw thread to move up and down along the screw, so as to change the position of the dust detection sensor in the smart cabinet body, and can detect the dust content at different positions and heights in the smart cabinet body.

[0005] Devices such as those in the above - mentioned comparative documents, although they can detect the dust content inside the cabinet, still have some deficiencies in actual use: First of all, it relies on a simple filter screen to block dust in the outside air. However, this can only slow down the speed of dust accumulation to a certain extent and cannot fundamentally solve the problem. As time goes by, the dust accumulated on the filter screen will increase the resistance of air circulation, reduce the heat dissipation efficiency, and may even cause false triggering or failure of the alarm device. In addition, when the filter screen reaches its dust - carrying limit, manual cleaning or replacement is required, which is both time - consuming and increases the maintenance cost. More importantly, if there are no effective measures to prevent fine particles from entering the cabinet again during the cleaning process, it may cause secondary pollution and affect the cleanliness inside the cabinet.

[0006] Secondly, after detecting that the dust content inside the cabinet is too high, manual cleaning is still required, which is not only time - consuming and laborious, but also there are certain safety hazards when manually cleaning deep inside the cabinet.

[0007] In view of the above problems, there is an urgent need for an efficient dust management system that can automatically detect the dust content inside the cabinet and has a self - cleaning function. Summary of the Invention

In addition, the reciprocating rotational movement of the diversion blades helps to evenly blow the surface of the power components, further improving the cleaning efficiency and quality, and ensuring the stability of the equipment performance and service life.

[0025] Please refer to the attached Figures 1 to 6 As shown, this embodiment provides a dust detection device for a server cabinet, including a cabinet 1, and a dust detector is installed inside the cabinet 1. Ventilation slots 11 are opened on both sides of the cabinet 1.

[0026] A filtering component 2, which is arranged in the ventilation slot 11 and is used for filtering the air entering the cabinet 1; A guiding component 3, which is also arranged in the ventilation slot 11 and is located inside the filtering component 2; A warning component 4, which is arranged at the upper end of the cabinet 1; A limiting component 5, which is arranged at the lower end of the cabinet 1; A dust extraction component 6, which is arranged on the cabinet 1 and is used for extracting dust; A mounting rack 7, which is arranged inside the cabinet 1 and is used for mounting power components; Among them, the dust extraction assembly 6 includes a first dust extraction part 61, the first dust extraction part 61 is installed on the back of the cabinet 1, a second dust extraction part 62 is installed on the bottom surface of the cabinet 1, a linkage part 63 is arranged between the first dust extraction part 61 and the second dust extraction part 62, and a control part 64 is also arranged on the bottom surface of the cabinet 1.

[0027] In this embodiment, an alarm device is installed on the cabinet 1, and the alarm device can adopt a buzzer and a warning light (not shown in the figure).

[0028] Secondly, please refer to again Figures 6 to 11 The filtering assembly 2 includes a movable slot 21, the movable slot 21 is opened above the ventilation slot 11, a filter plate 22 is slidably connected in the ventilation slot 11 in the vertical direction, and the upper end of the filter plate 22 penetrates into the movable slot 21. A first spring 23 is fixedly connected between the upper end of the filter plate 22 and the inner wall of the movable slot 21. A cleaning member 24 is also arranged at the filter plate 22. Among them, the cleaning member 24 includes a scraping member 241, the scraping member 241 is arranged on the side surface of the filter plate 22, the upper and lower ends of the scraping member 241 are fixedly connected with second springs 242 distributed in an array, and the other ends of the second springs 242 are fixedly connected with the inner wall of the ventilation slot 11. The lower end of the scraping member 241 is fixedly connected with first vertical rods 243 distributed in an array, and the lower ends of the first vertical rods 243 penetrate to the outside of the cabinet 1 and are fixedly connected with a first cross rod 244 at the lower ends.

[0029] Secondly, please refer to again Figure 1 and Figure 2 The warning assembly 4 includes a first support frame 41, the first support frame 41 is fixedly connected to the top surface of the cabinet 1, the upper end of the first support frame 41 is rotatably connected with a rotating rod 42 through a bearing, a first round rod 43 is fixedly connected to the rotating rod 42, a second support frame 44 is also fixedly connected to the top surface of the cabinet 1, a second round rod 45 is slidably connected to the second support frame 44, a touch switch 46 is fixedly installed at the upper end of the second support frame 44, one end of the first round rod 43 is fixedly connected with a third round rod 47, a lifting rod 48 is fixedly connected to the top surface of the filter plate 22, and the upper end of the lifting rod 48 penetrates to the outside of the cabinet 1 and is fixedly connected with a pull ring 49, and the end of the third round rod 47 is inserted into the pull ring 49.

[0030] In this embodiment, during use, the cabinet 1 realizes the circulation of internal and external air through the ventilation slots 11 on both sides thereof, thereby achieving the effect of heat dissipation. When the outside air enters through the ventilation slots 11, it will pass through the filter plate 22 for filtration to block dust and reduce the dust accumulation inside the cabinet 1. As time goes by, after the cabinet 1 is continuously used, more and more dust will accumulate on the filter plate 22, resulting in a gradual increase in its weight. As the weight of the filter plate 22 increases, it will move downward under the action of gravity and exert a tensile effect on the first spring 23. The downward movement of the filter plate 22 will drive the lifting rod 48 and the pull ring 49 to move downward together, and then the downward movement of the pull ring 49 will drive the third round rod 47 to move downward. The downward movement of the third round rod 47 will in turn cause one end of the first round rod 43 to move downward and cause the rotating rod 42 to rotate on the first support frame 41. At this time, the other end of the first round rod 43 will tilt up and push the second round rod 45 to move upward along the second support frame 44. In addition, the two parts of the first round rod 43 at both ends of the rotating rod 42 are designed with one end longer and the other end shorter. By using the lever principle, the stroke of the filter plate 22 is amplified, enabling the staff to more intuitively observe the amount of dust accumulated on the filter plate 22.

[0031] It should be noted that: the filter plate 22 is composed of a frame and a dust-proof net, and the dust-proof net is fixedly connected inside the frame. The warning component 4 is made of lightweight materials.

[0032] When the filter plate 22 moves downward to a certain extent and the stretching amount of the first spring 23 reaches a preset value (corresponding to the dust weight ≥ 50 g), the second round rod 45 moves to the uppermost end and contacts the touch switch 46, and then the limiting component 5 starts to operate; after the touch switch 46 is touched, the alarm device is turned on to remind the maintenance personnel.

[0033] Next, please also refer to Figures 6 to 11 , the diversion component 3 includes an installation groove 31, the installation groove 31 is opened on the side of the ventilation slot 11, and the ventilation slot 11 is rotationally connected with diversion blades 32 through bearings and distributed in an array, and the central rotating shaft of the diversion blades 32 extends into the installation groove 31 and is fixedly installed with a transmission gear 33. A guide rod 34 is fixedly connected in the installation groove 31, a rack 35 is slidably connected to the guide rod 34, a third spring 36 is fixedly connected between the upper end of the rack 35 and the inner wall of the installation groove 31, the lower end of the rack 35 is fixedly connected with a second vertical rod 37, and the lower end of the second vertical rod 37 penetrates to the outside of the cabinet 1 and is fixedly connected with a second cross rod 38 at its lower end.

[0034] In this embodiment, in the initial state, as Figure 7 and Figure 8As shown, the filter plate 22 is in the topmost position. The rack 35 is pulled downward, and the third spring 36 is stretched (at this time, the guide vane 32 is parallel to the bottom surface of the cabinet 1); at the same time, the scraping member 241 is also pulled downward, the upper second spring 242 is stretched, and the lower second spring 242 is compressed. The first cross bar 244 and the second cross bar 38 are respectively restricted by the first pressing block 53 and the second pressing block 54, so that the rack 35 and the scraping member 241 cannot move upward.

[0035] When the second round rod 45 moves to the topmost position and touches the touch switch 46, the electric push rod 51 immediately extends, driving the first pressing block 53 and the second pressing block 54 to move to the right (as Figure 11 shown). During the process of the first pressing block 53 moving to the right, the second cross bar 38 gradually loses the suppression of the first pressing block 53. Under the restoring force of the third spring 36, it drives the rack 35 to move upward along the guide rod 34. The rack 35 meshes with the transmission gear 33 for transmission, thereby promoting the rotation of the guide vane 32. When the second cross bar 38 completely loses the suppression of the first pressing block 53, the rack 35 moves to the upper reset position, and the guide vane 32 rotates by ninety degrees (at this time, the guide vane 32 is perpendicular to the bottom surface of the cabinet 1). Multiple guide vanes 32 cooperate with each other to close the ventilation slot 11. At this time, air cannot enter the interior of the cabinet 1 along the ventilation slot 11.

[0036] Please refer to again Figure 9 and Figure 11 As shown in, the limiting component 5 includes an electric push rod 51. The electric push rod 51 is fixedly installed on the bottom surface of the cabinet 1. The bottom surface of the cabinet 1 is also fixedly installed with a first slide rail 52. The first slide rail 52 is slidably connected with a first pressing block 53 and a second pressing block 54, and the first pressing block 53 and the second pressing block 54 are fixedly connected. The first pressing block 53 is fixedly connected to the telescopic end of the electric push rod 51.

[0037] In this embodiment, when the second cross bar 38 has just completely got rid of the restraint of the first pressing block 53, the first cross bar 244 is still restricted by the second pressing block 54. As the electric push rod 51 extends, the first pressing block 53 and the second pressing block 54 continue to move to the right. When the second pressing block 54 has undergone a certain displacement, the first cross bar 244 will suddenly lose the acting force of the second pressing block 54. At this time, the second springs 242 at the upper and lower ends of the scraping member 241 quickly release energy, pushing the scraping member 241 to move along the filter plate 22 to remove the dust accumulated on the surface of the filter plate 22. The elastic force of the second springs 242 enables the scraping member 241 to make several reciprocating movements on the surface of the filter plate 22, thereby achieving the goal of cleaning the filter plate 22 and ensuring the smoothness of air circulation and ventilation effect. At the same time, the ventilation slot 11 is closed by multiple guide vanes 32 to prevent a large number of fine particulate impurities generated during the cleaning process from passing through the filter plate 22 and entering the interior of the cabinet 1.

[0038] After the cleaning operation is completed, the staff can pull down the second crossbar 38 and the first crossbar 244. The downward movement of the first crossbar 244 will drive the first vertical bar 243 and the scraping member 241 to move downward; the downward movement of the second crossbar 38 will drive the second vertical bar 37 and the rack 35 to move downward, so that the scraping member 241 and the guide vane 32 return to their initial positions. Subsequently, by controlling the shortening of the electric push rod 51, the first pressing block 53 and the second pressing block 54 return to their initial states, and continue to limit the first crossbar 244 and the second crossbar 38.

[0039] Please refer to again Figure 4 、 Figure 7 and Figure 13 , the first dust extraction part 61 includes a first ventilation hood 611, the first ventilation hood 611 is fixedly connected to the back of the cabinet 1, a first filter screen 612 is fixedly connected to the inner wall of the first ventilation hood 611, a dust collection box 613 is communicated with the lower end of the first ventilation hood 611, and a baffle is connected to the lower end of the dust collection box 613 in a pull-out manner. A motor 614 is fixedly installed on the first ventilation hood 611, an output shaft of the motor 614 is fixedly connected to a driving rod 615, and the driving rod 615 is rotatably connected to the first filter screen 612. A first fan blade 616 is installed on the driving rod 615, a scraper 617 is also fixedly connected to the driving rod 615, hollow tubes 618 are connected in an array in the ventilation groove 11, and slot holes are arranged in an array on the hollow tubes 618. An air extraction pipe 619 is communicated with the first ventilation hood 611, and the air extraction pipe 619 is connected to the hollow tubes 618 through a plurality of shunt tubes.

[0040] In this embodiment, during the cleaning process of the filter plate 22, the motor 614 is first started, and the motor 614 drives the driving rod 615 to rotate. The rotation of the driving rod 615 further drives the first fan blade 616 and the scraper 617 to rotate. The rotation of the first fan blade 616 acts on the inside of the first ventilation hood 611, generating a negative pressure effect. Under the action of the negative pressure, the hollow tubes 618 are evacuated through the air extraction pipe 619. At this time, the fine particles removed from the filter plate 22 are sucked into the hollow tubes 618 by the airflow, ensuring the cleanliness of the ventilation groove 11 area. Subsequently, the fine particles carried by the airflow enter the inside of the first ventilation hood 611 through the air extraction pipe 619. Inside the first ventilation hood 611, the fine particles are blocked by the first filter screen 612 and cannot continue to move forward. At the same time, the rotating scraper 617 can remove the fine particles adhering to the side of the first filter screen 612 and drop them into the dust collection box 613.

[0041] Please refer to again Figure 14The second dust extraction part 62 includes a second ventilation hood 621, which is fixedly connected to the bottom surface of the cabinet 1 and communicated with the interior of the cabinet 1. The inner wall of the second ventilation hood 621 is fixedly connected with a guide seat 622 and a second filter screen 623. The second ventilation hood 621 is rotatably connected with a first linkage rod 624 through a bearing, and a second fan blade 625 is fixedly installed on the upper end of the first linkage rod 624.

[0042] The second ventilation cover 621 is provided with a sealing door, which can be opened to clean the dust blocked on the second filter screen 623. The guide seat 622 is funnel-shaped, which facilitates the dust to enter along the guide seat 622, but is not easy to be discharged along the guide seat 622. Please refer again Figure 3 , Figure 4 , Figure 13 , Figure 14 and Figure 15 The linkage part 63 includes a second linkage rod 631, which is rotatably connected to the back of the cabinet 1 through a bearing, and the upper end of the second linkage rod 631 extends to the interior of the first ventilation hood 611 and is rotatably connected to the first ventilation hood 611 through a sealed bearing. The upper end of the second linkage rod 631 is fixedly installed with a first bevel gear 632, and the driving rod 615 is installed with a second bevel gear 633. The lower end of the second linkage rod 631 is fixedly installed with a first linkage gear 634, and the lower end of the first linkage rod 624 is fixedly installed with a second linkage gear 635 and a third linkage gear 636.

[0043] In this embodiment, when the dust detector in the cabinet 1 detects that a lot of dust has accumulated in the cabinet 1, the motor 614 is started. The operation of the motor 614 drives the driving rod 615 to rotate, thereby rotating the second bevel gear 633. The meshing transmission of the second bevel gear 633 and the first bevel gear 632 causes the rotation of the second linkage rod 631. The rotation of the second linkage rod 631 in turn drives the rotation of the first linkage gear 634, which is transmitted to the second linkage gear 635 through a toothed belt, thereby rotating the first linkage rod 624. The rotation of the first linkage rod 624 causes the second fan blade 625 to rotate, thereby generating negative pressure in the second ventilation hood 621. This negative pressure effect causes the air in the cabinet 1 to be sucked into the second ventilation hood 621, and the dust in the cabinet 1 is discharged under the impetus of the airflow.

[0044] Please refer again Figure 3 , Figure 9 , Figure 12, the control unit 64 includes a third linkage rod 641 which is rotatably connected to the bottom surface of the cabinet 1 through a bearing. A cam 642 and a fourth linkage gear 643 are fixedly installed on the third linkage rod 641. A second slide rail 644 is fixedly connected to the bottom surface of the cabinet 1. A third pressing block 645 is slidably connected to the second slide rail 644. A fourth spring 646 is sleeved on the right end of the second slide rail 644.

[0045] In this embodiment, when the dust content detection result inside the cabinet 1 indicates that there is a lot of dust, the electric push rod 51 is controlled to extend, thereby driving the first pressing block 53 and the second pressing block 54 to move to specific positions. Specifically, it moves until the second cross bar 38 is no longer pressed by the first pressing block 53, while the first cross bar 244 is still pressed by the second pressing block 54. At the same time, the third linkage gear 636 meshes with the fourth linkage gear 643 to drive the third linkage rod 641 to rotate. The rotation of the third linkage rod 641 drives the cam 642 to rotate. When the cam 642 rotates to a specific position, it will contact the third pressing block 645, push the third pressing block 645 to move along the second slide rail 644, and compress the fourth spring 646. As the cam 642 continues to rotate, the third pressing block 645 finally loses contact with the cam 642 and returns to its original position under the restoring force of the fourth spring 646. This cycle repeats, causing the third pressing block 645 to perform a reciprocating motion on the second slide rail 644. Since the second cross bar 38 is no longer pressed by the first pressing block 53 at this time, it will move upward to the position where the third pressing block 645 is located and stop rising due to the restriction of the third pressing block 645. During the reciprocating motion of the third pressing block 645, when it is pushed by the cam 642 and moves, it will gradually press down the second cross bar 38; when the third pressing block 645 resets, the second cross bar 38 will gradually get rid of the pressure of the third pressing block 645, so as to rise and fall with the movement of the third pressing block 645. The rising and falling of the second cross bar 38 drives the second vertical bar 37 to move, thereby causing the rack 35 to rise and fall. During the rising and falling process of the rack 35, it meshes with the transmission gear 33, prompting the transmission gear 33 and the flow guiding blades 32 to perform a reciprocating rotation. During the process of cleaning the dust inside the cabinet 1, the air inside the cabinet 1 is quickly pumped out by the second dust extraction part 62, while the external air enters through the ventilation slot 11 and enters the cabinet 1 under the guidance of the flow guiding blades 32. At this time, through the reciprocating rotational motion of the flow guiding blades 32, the airflow entering the cabinet 1 can be effectively guided. This motion mode enables the airflow to evenly blow to all corners of the power components, effectively blowing off the dust particles attached to the surface of the power components. With the continuous movement of the airflow, these blown-off dust particles will be guided by the airflow and finally enter the interior of the second ventilation cover 621. Through such a design, not only the efficiency of cleaning the power components is improved, but also it is ensured that the dust will not redeposit inside the cabinet 1, thus significantly enhancing the overall cleaning effect.

[0046] It should be noted that: both the first fan blade 616 and the second bevel gear 633 are mounted on the drive rod 615 through a ratchet-pawl mechanism (as Figure 15 shown). Specifically, the first fan blade 616 and the second bevel gear 633 are rotatably connected to the drive rod 615 through bearings, and a circular ring is provided on the first fan blade 616 and the second bevel gear 633. A pawl is installed inside the circular ring, and a return spring is connected between the pawl and the circular ring. A ratchet is fixedly provided on the drive rod 615. When the ratchet on the drive rod 615 meshes with the pawl on the first fan blade 616, the first fan blade 616 will rotate together with the drive rod 615, and at this time, the ratchet on the second bevel gear 633 does not mesh with the pawl on the second bevel gear 633, so the second bevel gear 633 remains stationary. On the contrary, when the motor 614 rotates in reverse, the second bevel gear 633 will rotate, while the first fan blade 616 remains stationary. The transmission mechanism of the ratchet-pawl belongs to the well-known technology in the prior art, so it will not be described in detail. The purpose of this mechanism is to achieve that when the first fan blade 616 rotates with the drive rod 615, the second bevel gear 633 remains stationary, and at this time, the first dust extraction part 61 is in the working state; when the second bevel gear 633 rotates with the drive rod 615, the first fan blade 616 remains stationary, and at this time, the second dust extraction part 62 starts to work. By controlling the forward or reverse rotation of the motor 614, the control of the first dust extraction part 61 or the second dust extraction part 62 can be realized.

[0047] The touch switch 46, the electric push rod 51, the motor 614, and the dust detector and alarm device installed on the cabinet 1 all use products that have been publicly available on the market at present. When selecting models, under the premise of suitable specifications and usage scenarios, products that meet the requirements of this application should be selected as much as possible. Specific model specifications are not limited here.

[0048] A method for detecting dust in a server cabinet includes the following steps: Step 1: Filter the air entering the cabinet 1 from the ventilation slot 11 through the filter plate 22 on the filter assembly 2; Step 2: When too much dust adheres to the filter plate 22, the filter plate 22 moves downward under its own gravity, which prompts the warning assembly 4 to displace and triggers the limit assembly 5 to move; Step 3: After the limit assembly 5 moves, it prompts the diversion assembly 3 to close the ventilation slot 11 and cleans the filter plate 22 through the cleaning member 24; Step 4: While cleaning the filter plate 22, start the operation of the first dust extraction part 61 to extract the dust generated during cleaning; Step 5: When the dust detector installed inside the cabinet 1 detects that the dust content in the cabinet 1 is relatively high, start the second dust extraction part 62 to extract the air inside the cabinet 1 and carry out the dust under the action of the air flow.

[0049] The working principle of the present invention is: By arranging a filtering component 2 in the ventilation slot 11 of the server cabinet 1, the air entering the cabinet 1 is filtered by the filter plate 22 to block dust. As the dust accumulates on the filter plate 22 and its weight increases, it moves downward, triggering the warning component 4 and starting the diversion component 3 through the limit component 5 to close the ventilation slot 11, preventing fine particles from entering the cabinet 1 again during the cleaning process. At the same time, the cleaning part 24 starts to automatically clean the surface of the filter plate 22, and the dust generated during cleaning is extracted by the first dust extraction part 61. When the dust detector installed inside the cabinet 1 detects that the dust content in the cabinet 1 exceeds the standard, the second dust extraction part 62 is started, generating negative pressure to take the dust in the cabinet 1 out with the air flow to ensure the cleanliness of the internal environment of the cabinet 1.

[0050] The entire system coordinates the operation of each component through an intelligent control mechanism, including controlling the forward and reverse rotation of the motor 614 to operate the dust extraction components (the first dust extraction part 61 and the second dust extraction part 62) at different positions, and using a linkage design to achieve the reciprocating rotational movement of the diversion blades 32 to guide the air flow to evenly blow the surface of the power components, so as to effectively remove dust and maintain a good heat dissipation effect of the equipment.
