When the air volume of the fan is detected, the fan covers the air inlet, the air outlet of the fan is connected to the air inlet, the fan blows the gas from the air inlet into the first cavity, the air volume detection sensor is located in the first cavity, and the air volume detection sensor detects the air volume, thereby realizing the air volume detection of the wind.

[0008] In some embodiments, the air outlet is located on a side of the air volume detection box away from the detection station along the third direction, and the third direction intersects with the surface of the workbench with the detection station. The air outlet is located on a side of the air volume detection box away from the detection station along the third direction, so that the gas can be discharged to a side away from the air volume detection component and the fan, which can reduce the influence of the discharged gas on the detection result.

[0009] In some embodiments, the air volume detection assembly further includes: a first sealing ring connected to the outer side wall of the air volume detection box, and the first sealing ring surrounds the air inlet.

When the first movable component contacts the positioning sensor, it indicates that the first movable component has moved to the edge area of ​​the inner space of the outer cover.

[0018] In some embodiments, the first moving assembly further includes: a first driving member connected to the workbench, the first driving member connected to the first connecting member, and the first driving member is configured to drive the first connecting member to move along the first direction.

[0019] In some embodiments, the fan detection device further includes: a second moving component connected to the surface of the workbench with the detection station, the second moving component can move along the second direction, and the moving path of the second moving component passes through the detection station.

After the inspection is completed, the second slider is controlled to slide, thereby controlling the fan connected to the second connector to move away from the detection station.

[0021] In some embodiments, the second moving assembly further includes: a second driving member connected to the workbench, the second driving member connected to the second connecting member, and the second driving member is configured to drive the second connecting member to move along the second direction.

[0043] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0044] Large-scale electrical devices, such as energy storage containers, have many batteries integrated inside. During use, the batteries will produce toxic and harmful gases. These gases gather inside the container and can easily cause safety accidents. In order to allow the gas to be discharged smoothly, a fan is usually installed on the container to discharge the gas. Before the fan is put into use, it is necessary to test the fan, and only fans that pass the test can be put into use. The various performances of the fan are tested separately, and the fan circulates between different testing devices, involving the disassembly and reinstallation of the fan, which requires a lot of time and manpower, a long testing time, and low efficiency in testing the fan.

[0045] The embodiments of the present application provide a fan detection device and a fan detection system. The fan detection device can perform two different performance tests on the fan, and the fan detection device has a wider range of applications. When performing different tests on the fan, only the first moving component needs to be moved, and the fan does not need to be moved, and the fan does not need to be disassembled and reinstalled. The detection process is simpler, the detection time is shortened, and the efficiency of detecting the fan is improved.

[0046] The fan detection device and fan detection system disclosed in the embodiments of the present application detect the fan, and after the detection, the fan can be used in electrical devices such as vehicles, ships or aircraft, but is not limited to it.

[0047] The present application provides a fan detection device. Figure 1 This is a schematic diagram of the structure of a fan detection device according to some embodiments of the present application. Figure 2 This is a schematic diagram of the structure of the fan detection device in another state in some embodiments of the present application. Figure 1 and Figure 2The fan detection device includes a workbench 10, a first moving assembly 20, an air volume detection assembly 30 and an air tightness detection assembly 40. The workbench 10 has a detection station, the first moving assembly 20 is connected to the surface of the workbench 10 with the detection station, the first moving assembly 20 can move along a first direction X, the first moving assembly 20 is located at one side of the detection station along a second direction Y, the first direction X and the second direction Y are both parallel to the surface of the workbench 10 with the detection station, and the first direction X intersects with the second direction Y. The air volume detection assembly 30 and the air tightness detection assembly 40 are both connected to the first moving assembly 20.

[0048] In the embodiment of the present application, the workbench 10 can be used to install the components of the first moving assembly 20, and the workbench 10 provides support for the first moving assembly 20, the air volume detection assembly 30, and the air tightness detection assembly 40. For example, the workbench 10 can be a work table, or a mounting block, or a mounting plate, etc.

[0049] Exemplarily, the workbench 10 is a work table, and the inspection station may be a position on the tabletop of the work table for placing the fan 100 .

[0050] In some embodiments, during the process of the fan detection device detecting the fan 100, the workbench 10 is placed on the ground, and the surface of the workbench 10 with the detection station is generally parallel to the horizontal plane, or the angle between the surface of the workbench 10 with the detection station and the horizontal plane is less than 10°.

[0051] In some embodiments, the first direction X is perpendicular to the second direction Y, or the first direction X intersects with the second direction Y but is not perpendicular, for example, the angle between the first direction X and the second direction Y is less than 10°.

[0052] In an embodiment of the present application, the air volume detection component 30 and the air tightness detection component 40 are both connected to the first movable component 20. When the first movable component 20 moves along the first direction X, the first movable component 20 can drive the air volume detection component 30 and the air tightness detection component 40 to move along the first direction X.

[0053] In the embodiment of the present application, the air volume detection component 30 can detect the air volume of the fan. Only when the air volume of the fan is qualified can the toxic and harmful gases in the container be discharged in time. The air tightness detection component 40 can detect the air tightness of the fan to reduce the possibility that the air tightness of the container is affected by the poor air tightness of the fan.

[0054] When the fan detection device provided by the embodiment of the present application is used to detect the fan, the fan 100 is placed at the detection station, and then the first moving component 20 is moved. The first moving component 20 can drive the air volume detection component 30 and the air tightness detection component 40 to move along the first direction X, so that one of the air volume detection component 30 and the air tightness detection component 40 moves to the side of the fan 100 along the second direction Y, and the fan 100 is detected. After the detection is completed, the first moving component 20 is moved again, so that the other of the air volume detection component 30 and the air tightness detection component 40 moves to the side of the fan 100 along the second direction Y, and the fan 100 is detected. That is, the fan detection device can perform two different performance tests on the fan 100, and the fan detection device has a wider range of uses. Furthermore, when performing different tests on the fan 100, only the first movable assembly 20 needs to be moved, and the fan 100 does not need to be moved or disassembled or reinstalled. This simplifies the testing process, shortens the testing time, and improves the efficiency of testing the fan.

[0055] In the related art, since the fan 100 needs to be disassembled and reinstalled, during the disassembly and installation process, the components of the fan 100 may be damaged, affecting the performance and service life of the fan 100. The fan detection device provided in the embodiment of the present application does not require the fan 100 to be disassembled and reinstalled, thereby improving the performance and service life of the fan 100.

[0056] In an embodiment of the present application, the air volume detection component 30 and the air tightness detection component 40 are integrated together. The air volume detection component 30 and the air tightness detection component 40 can be supported by the workbench 10 at the same time. There is no need to set up two supporting members, which reduces the floor space. While increasing the function of the fan detection device, the volume of the fan detection device is reduced.

[0057] According to some embodiments of the present application, see Figure 1 and Figure 2 The air volume detection component 30 includes an air volume detection box 31, which is connected to the first movable component 20. The air volume detection box 31 has an air inlet 311, an air outlet 312 and a first cavity 313. The air inlet 311 and the air outlet 312 are both connected to the first cavity 313. The air inlet 311 is located on one side of the air volume detection box 31 along the second direction Y toward the detection station, and the air inlet 311 and the air outlet 312 are located on different sides of the air volume detection box 31.

[0058] Figure 3 This is a block diagram of a wind turbine detection device according to some embodiments of the present application. Figure 3 The air volume detection component 30 also includes an air volume detection sensor 32 , wherein the air volume detection sensor 32 is located in the first cavity 313 .

[0059] In the embodiment of the present application, the air volume detection box 31 can be a rectangular box, a cylindrical box, or any other regular or irregular box.

[0060] In the embodiment of the present application, the shapes of the air inlet 311 and the air outlet 312 are not limited, and the shapes of the air inlet 311 and the air outlet 312 can be rectangular, circular, or any other regular or irregular shapes.

[0061] In an embodiment of the present application, the air inlet 311 is located on one side of the air volume detection box 31 along the second direction Y toward the detection station. After the fan 100 is placed at the detection station, the fan 100 blows the gas from the air inlet 311 into the first cavity 313 and is discharged from the air outlet 312.

[0062] See also Figure 1 and Figure 2 ,exist Figure 1 The fan 100 covers the air inlet 311, and the air volume detection component 30 can detect the air volume of the fan 100. Figure 2 Although the air volume detection component 30 is opposite to the fan 100 , the fan 100 does not cover the air inlet 311 , and the air volume detection component 30 does not detect the air volume of the fan 100 at this time.

[0063] In an embodiment of the present application, when the air volume of the fan 100 is detected, the fan 100 covers the air inlet 311, the exhaust port of the fan 100 is connected to the air inlet 311, the fan 100 blows the gas from the air inlet 311 into the first cavity 313, the air volume detection sensor 32 is located in the first cavity 313, and the air volume detection sensor 32 detects the air volume, thereby realizing the air volume detection of the fan 100.

[0064] In an embodiment of the present application, the air inlet 311 and the air outlet 312 are located on different sides of the air volume detection box 31, so that the gas entering from the air inlet 311 can pass through the air volume detection sensor 32 and then be discharged from the air outlet 312, thereby improving the accuracy of air volume detection.

[0065] According to some embodiments of the present application, the air outlet 312 and the air inlet 311 may be located on opposite sides of the air volume detection box 31 along the second direction Y.

[0066] According to some embodiments of the present application, the air outlet 312 is located on a side of the air volume detection box 31 away from the detection station along the third direction Z, and the third direction Z intersects with the surface of the workbench 10 having the detection station.

[0067] In an embodiment of the present application, the third direction Z is perpendicular to the surface of the workbench 10 having the inspection station, or the third direction Z intersects with the surface of the workbench 10 having the inspection station but is not perpendicular, for example, the angle between the third direction Z and the surface of the workbench 10 having the inspection station is greater than or equal to 80° and less than 90°.

[0068] In an embodiment of the present application, the air outlet 312 is located on the side of the air volume detection box 31 along the third direction Z away from the detection station, so that the gas can be discharged to the side away from the air volume detection component 30 and the fan 100, thereby reducing the impact of the discharged gas on the detection results.

[0069] According to some embodiments of the present application, see Figure 2 The air volume detection assembly 30 also includes a first sealing ring 33 , which is connected to the outer wall of the air volume detection box 31 , and surrounds the air inlet 311 .

[0070] In some embodiments of the present application, the air inlet 311 is rectangular in shape, and the first sealing ring 33 may be a rectangular ring. In other embodiments of the present application, the air inlet 311 is circular in shape, and the first sealing ring 33 may be a circular ring. Of course, the shape of the first sealing ring 33 does not necessarily need to correspond to the shape of the air inlet 311. For example, if the air inlet 311 is rectangular in shape, the first sealing ring 33 may be a circular ring, or any other regular or irregular ring.

[0071] In some embodiments of the present application, the first sealing ring 33 may be made of rubber or silicone.

[0072] In an embodiment of the present application, when the air volume of the fan 100 is detected, the first sealing ring 33 is located between the exhaust port and the air inlet 311 of the fan 100. The first sealing ring 33 can reduce the leakage of gas from between the exhaust port and the air inlet 311 of the fan 100. As much gas as possible discharged from the exhaust port of the fan 100 enters the first cavity 313 through the air inlet 311, thereby improving the accuracy of the air volume detection of the fan 100.

[0073] According to some embodiments of the present application, see Figure 1 and Figure 2 The airtightness detection assembly 40 includes an airtightness detection box 41 and an air pump 43. The airtightness detection box 41 is connected to the first moving assembly 20. The airtightness detection box 41 has a vent 411 and a second cavity 412. The vent 411 is connected to the second cavity 412. The vent 411 is located on one side of the airtightness detection box 41 facing the detection station along the second direction Y. The air pump 43 is connected to the first moving assembly 20, and the air pump 43 is connected to the second cavity 412.

[0074] See also Figure 3The airtightness detection component 40 also includes a pressure sensor 42 , and the pressure sensor 42 is located in the second cavity 412 .

[0075] In the embodiment of the present application, the airtight detection box 41 may be a rectangular box, a cylindrical box, or any other regular or irregular box.

[0076] In the embodiment of the present application, the shape of the vent 411 is not limited, and the shape of the vent 411 can be rectangular, circular, or any other regular or irregular shape.

[0077] In an embodiment of the present application, the vent 411 is located on one side of the airtightness detection box 41 along the second direction Y toward the detection station. After the fan 100 is placed at the detection station, the fan 100 can cover the vent 411, and the pressure sensor 42 can perform airtightness detection on the fan 100.

[0078] In the embodiment of the present application, the vacuum pump 43 is connected to the second cavity 412 , and the vacuum pump 43 can extract the gas in the second cavity 412 , and at the same time, the vacuum pump 43 can also deliver gas to the second cavity 412 .

[0079] In an embodiment of the present application, when the air tightness test of the fan 100 is performed, the fan 100 covers the vent 411, and the vacuum pump 43 draws out the gas in the second cavity 412, so that the second cavity 412 is in a negative pressure state, and the pressure sensor 42 is located in the second cavity 412. The pressure sensor 42 detects the pressure in the second cavity 412, and determines whether the air tightness of the fan 100 is qualified by the pressure detected by the pressure sensor 42.

[0080] Exemplarily, the pressure in the second cavity 412 that decreases within the set time is less than or equal to the preset pressure, indicating that the air tightness of the fan 100 is qualified.

[0081] For example, the fan 100 covers the vent 411, the vacuum pump 43 extracts the gas in the second cavity 412, and the vacuum pump 43 is turned off. At this time, the pressure sensor 42 records the initial pressure once. Then the fan 100 and the air tightness detection component 40 are left to stand for a period of time. After the pressure in the second cavity 412 stabilizes, the pressure sensor 42 detects the pressure inside the second cavity 412 again, and observes and records the pressure change. According to the preset pressure attenuation threshold, the detected pressure change is analyzed. If the pressure in the second cavity 412 decays during the standing period and exceeds the preset pressure attenuation threshold, it can be determined that the air tightness of the fan 100 is unqualified and needs further investigation and repair.

[0082] According to some embodiments of the present application, see Figure 1 and Figure 2The airtightness detection assembly 40 further includes a second sealing ring 44 connected to the outer side wall of the airtightness detection box 41 , and the second sealing ring 44 surrounds the vent 411 .

[0083] In some embodiments of the present application, the shape of the vent 411 is rectangular, and the second sealing ring 44 can be a rectangular ring. In other embodiments of the present application, the shape of the vent 411 is circular, and the second sealing ring 44 can be a circular ring. Of course, the shape of the second sealing ring 44 does not necessarily need to correspond to the shape of the vent 411. For example, the shape of the vent 411 is rectangular, and the second sealing ring 44 can be a circular ring, or any other regular or irregular ring.

[0084] In some embodiments of the present application, the second sealing ring 44 may be made of rubber or silicone.

[0085] In an embodiment of the present application, when the air tightness test is performed on the fan 100, the second sealing ring 44 is located between the exhaust port and the vent 411 of the fan 100. The second sealing ring 44 can reduce the gas from entering the second cavity 412 from between the exhaust port and the vent 411 of the fan 100, thereby reducing the impact of the poor sealing between the exhaust port and the vent 411 of the fan 100 on the air tightness test results, thereby improving the accuracy of the air tightness test of the fan 100.

[0086] According to some embodiments of the present application, see Figure 1 and Figure 2 The fan detection device also includes an insulation detection component 50, which is connected to the surface of the workbench 10 with the detection station. The insulation detection component 50 and the detection station are located on the same side of the first moving component 20, and the insulation detection component 50 is located on one side of the detection station along the second direction Y.

[0087] In the embodiment of the present application, the insulation detection component 50 is used to detect the insulation of the fan 100 to reduce safety accidents caused by leakage of the fan 100.

[0088] In an embodiment of the present application, the insulation detection component 50 and the detection station are located on the same side of the first movable component 20. When the fan 100 is placed at the detection station, the air volume detection and insulation detection of the fan 100 can be performed simultaneously.

[0089] In some embodiments of the present application, since the fan 100 needs to be in the on state when the air volume is detected, and the fan 100 also needs to be in the on state when the insulation is detected, the fan 100 can be tested for insulation while the air volume is detected to improve the detection efficiency.

[0090] In an embodiment of the present application, the fan detection device also includes an insulation detection component 50, that is, one fan detection device can perform air volume detection, air tightness detection and insulation detection on the fan 100, that is, the fan detection device can perform three different performance tests on the fan 100, and the fan detection device has a wider range of uses.

[0091] According to some embodiments of the present application, see Figure 1 and Figure 2 The insulation detection assembly 50 includes a mounting rod 51 and an insulation detection element 52. The mounting rod 51 extends along the third direction Z, and one end of the mounting rod 51 is connected to the surface of the workbench 10 with the detection station. The insulation detection element 52 is rotatably connected to the other end of the mounting rod 51, and the rotation axis of the insulation detection element 52 is parallel to the second direction Y.

[0092] In the embodiment of the present application, the mounting rod 51 is used to mount the insulation detection element 52 to improve the stability of the insulation detection element 52 .

[0093] In the embodiment of the present application, the insulation detection element 52 is used to detect whether the insulation of the wind turbine 100 is qualified.

[0094] In some embodiments of the present application, the length direction of the insulation detection element 52 is perpendicular to the second direction Y.

[0095] In the embodiment of the present application, when performing insulation testing on the fan 100, the insulation testing element 52 is first rotated so that the insulation testing element 52 is away from the testing station (see Figure 2 ), it is convenient to place the fan 100 at the detection station. After the fan 100 is placed at the detection station, the insulation detection element 52 is rotated again so that the insulation detection element 52 contacts the fan 100 (see Figure 1 ), the insulation detection element 52 can perform insulation detection on the fan 100, and at the same time, the insulation detection element 52 and the air volume detection component 30 (or the air tightness detection component 40) are respectively located on the opposite sides of the fan 100 along the second direction Y. The insulation detection element 52 and the air volume detection component 30 (or the air tightness detection component 40) fix the fan 100, thereby improving the stability of the fan 100 during the detection process and improving the accuracy of the detection results.

[0096] In some embodiments of the present application, the insulation detection component 50 may further include a rotating motor 53 , which is connected to the insulation detection element 52 , and is used to drive the insulation detection element 52 to rotate.

[0097] According to some embodiments of the present application, see Figure 1 and Figure 2The insulation detection assembly 50 includes two mounting rods 51 and two insulation detection elements 52. The two mounting rods 51 are respectively located on opposite sides of the detection station along the second direction Y, and the two insulation detection elements 52 are respectively connected to the other ends of the two mounting rods 51 in a one-to-one correspondence.

[0098] In an embodiment of the present application, when the fan 100 is detected, the two insulation detection elements 52 are respectively located on opposite sides of the fan 100 along the second direction Y. The two insulation detection elements 52 can both detect the fan 100. At the same time, the two insulation detection elements 52 fix the fan 100 on both sides of the fan 100 to improve the stability of the fan 100.

[0099] According to some embodiments of the present application, Figure 4 Schematic diagram of the structure of the fan detection device in some other embodiments of the present application. Figure 4 The fan detection device also includes an outer cover 60, which is connected to the surface of the workbench 10 with the detection station, and the outer cover 60 covers the first moving component 20, the air volume detection component 30 and the air tightness detection component 40.

[0100] In some embodiments of the present application, the shape of the outer cover 60 may be a cuboid, a sphere, or a hemisphere.

[0101] See also Figure 4 A first opening 61 may be provided on one side of the outer cover 60 along the second direction Y. The detection station and the first opening 61 are located on the same side of the first movable assembly 20 . The first opening 61 is opposite to the detection station, which facilitates the placement of the fan 100 .

[0102] In some embodiments of the present application, when the air volume detection assembly 30 includes an air volume detection box 31, a second opening 62 can be set on the top wall of the outer cover 60 away from the workbench 10 along the second direction Y, and the air outlet 312 extends out of the second opening 62. The air outlet 312 can exhaust the air blown into the first cavity 313 by the fan 100 to the outside of the outer cover 60, thereby reducing the influence of the air discharged from the air outlet 312 on the air volume detection.

[0103] In some embodiments of the present application, the second opening 62 extends along the first direction X to prevent the second opening 62 from affecting the movement of the air volume detection assembly 30 .

[0104] In an embodiment of the present application, the outer cover 60 covers the first movable component 20, the air volume detection component 30 and the air tightness detection component 40 to reduce the impact of the external environment on the detection of the fan 100. At the same time, the outer cover 60 can also reduce the collision of other external components with the first movable component 20, the air volume detection component 30 and the air tightness detection component 40, thereby reducing the risk of damage to the fan detection device.

[0105] According to some embodiments of the present application, Figure 5 Schematic diagram of a cross section of a wind turbine detection device according to some embodiments of the present application. Figure 5 The fan detection device also includes a positioning sensor 70, which is connected to the inner wall of the outer cover 60. The positioning sensor 70 is located on at least one side of the first movable component 20 along the first direction X. The positioning sensor 70 is communicatively connected to the first movable component 20. The positioning sensor 70 is configured to control the first movable component 20 to stop moving when the first movable component 20 contacts the positioning sensor 70.

[0106] In some embodiments of the present application, the positioning sensor 70 and the first movable component 20 may be directly connected in communication. When the first movable component 20 is in contact with the positioning sensor 70 , the positioning sensor 70 directly controls the first movable component 20 to stop moving.

[0107] In some other embodiments of the present application, the positioning sensor 70 and the first movable component 20 can be indirectly communicatively connected. Exemplarily, the fan detection device also includes a controller 90, which is communicatively connected to the positioning sensor 70 and the first movable component 20. The first movable component 20 is in contact with the positioning sensor 70, and the positioning sensor 70 sends a signal to the controller 90. After receiving the signal, the controller 90 controls the first movable component 20 to stop moving.

[0108] In the embodiment of the present application, the first moving assembly 20, the air volume detection assembly 30 and the air tightness detection assembly 40 are generally located in the middle area of ​​the inner space of the outer cover 60, the positioning sensor 70 is connected to the inner side wall of the outer cover 60, and the positioning sensor 70 is located at the edge area of ​​the inner space of the outer cover 60. When the first moving assembly 20 contacts the positioning sensor 70, it means that the first moving assembly 20 has moved to the edge area of ​​the inner space of the outer cover 60. If the first moving assembly 20 continues to move, it may cause the first moving assembly 20 to collide with the outer cover 60, causing damage to the first moving assembly 20 or the outer cover 60. When the first moving assembly 20 contacts the positioning sensor 70, the positioning sensor 70 can timely control the first moving assembly 20 to stop moving, reduce the possibility of the first moving assembly 20 colliding with the outer cover 60, and reduce the possibility of damage to the fan detection device.

[0109] Exemplarily, the positioning sensor 70 may include a laser sensor or a contact switch.

[0110] According to some embodiments of the present application, see Figure 1 and Figure 2The first moving assembly 20 includes a first slide rail 21, a first slider 22 and a first connecting member 23. The first slide rail 21 extends along the first direction X, the first slide rail 21 is connected to the surface of the workbench 10 with the detection station, the first slider 22 is slidably connected to the first slide rail 21, the first connecting member 23 is connected to the first slider 22, and the air volume detection assembly 30 and the air tightness detection assembly 40 are both connected to the first connecting member 23.

[0111] In some embodiments of the present application, the first moving assembly 20 may include a first slide rail 21 .

[0112] In some other embodiments of the present application, the first moving assembly 20 may include two or more first slide rails 21. For example, the first moving assembly 20 includes two first slide rails 21, and the two first slide rails 21 are arranged along the second direction Y at intervals.

[0113] In some embodiments of the present application, a first slide rail 21 may be connected to a first slide block 22 .

[0114] In some other embodiments of the present application, at least two first sliding blocks 22 may be connected to one first sliding rail 21 .

[0115] In the embodiment of the present application, the first connecting member 23 is connected to all the first sliding blocks 22. Exemplarily, the first connecting member 23 may be a connecting plate.

[0116] In an embodiment of the present application, when moving the air volume detection component 30 or the air tightness detection component 40, the first slider 22 is controlled to slide on the first slide rail 21, and the first slider 22 drives the first connecting member 23 to slide, thereby controlling the air volume detection component 30 and the air tightness detection component 40 connected to the first connecting member 23 to move along the first direction X.

[0117] At the same time, the air volume detection component 30 and the air tightness detection component 40 are both connected to the first connecting member 23. When the first connecting member 23 moves, the air volume detection component 30 and the air tightness detection component 40 can move at the same time. For example, if the air volume detection is first performed on the fan 100, when the air tightness detection is required, the first connecting member 23 is controlled to move. During the movement of the first connecting member 23, the air volume detection component 30 and the air tightness detection component 40 are driven to move at the same time. When the air tightness detection component 40 moves to the detection station, the air volume detection component 30 moves away from the detection station. There is no need to distribute and control the air volume detection component 30 and the air tightness detection component 40, which is more convenient.

[0118] According to some embodiments of the present application, see Figure 1 and Figure 2The first moving assembly 20 also includes a first driving member 24, the first driving member 24 is connected to the workbench 10, the first driving member 24 is connected to the first connecting member 23, and the first driving member 24 is configured to drive the first connecting member 23 to move along the first direction X.

[0119] Exemplarily, the first driving member 24 may be a cylinder, or the first driving member 24 may be a motor.

[0120] In the embodiment of the present application, a first driving member 24 is provided to drive the first connecting member 23 to move along the first direction X, which is more labor-saving.

[0121] According to some embodiments of the present application, see Figure 1 and Figure 2 The fan detection device also includes a second moving component 80, which is connected to the surface of the workbench 10 with the detection station. The second moving component 80 can move along the second direction Y, and the moving path of the second moving component 80 passes through the detection station.

[0122] In the embodiment of the present application, the second moving assembly 80 can be used to control the fan 100 to move along the second direction Y.

[0123] In an embodiment of the present application, during the inspection of the fan 100, the fan 100 can be placed on the second movable assembly 80, and the second movable assembly 80 drives the fan 100 to move to the inspection station for inspection. After the fan inspection is completed, the second movable assembly 80 moves the fan 100 away. The fan inspection device has a high automation rate and higher inspection efficiency.

[0124] According to some embodiments of the present application, see Figure 1 and Figure 2 The second moving assembly 80 includes a second slide rail 81, a second slider 82, and a second connecting member 83. The second slide rail 81 extends along the second direction Y, the second slide rail 81 is connected to the surface of the workbench 10 with the detection station, the second slider 82 is slidably connected to the second slide rail 81, and the second connecting member 83 is connected to the second slider 82.

[0125] In some embodiments of the present application, the second moving assembly 80 may include a second slide rail 81 .

[0126] In some other embodiments of the present application, the second moving assembly 80 may include two or more second slide rails 81. For example, the second moving assembly 80 includes two second slide rails 81, and the two second slide rails 81 are arranged along the first direction X at intervals.

[0127] In some embodiments of the present application, a second slide rail 81 may be connected to a second slide block 82 .

[0128] In some other embodiments of the present application, at least two second sliding blocks 82 may be connected to one second sliding rail 81 .

[0129] In the embodiment of the present application, the second connecting member 83 is connected to all the second sliding blocks 82. Exemplarily, the second connecting member 83 may include a connecting plate.

[0130] In the embodiment of the present application, when inspecting the fan 100, the fan 100 is connected to the second connecting member 83, and the second slider 82 is controlled to slide on the second slide rail 81. The second slider 82 drives the second connecting member 83 to slide, thereby controlling the fan 100 connected to the second connecting member 83 to move to the inspection station along the second direction Y. After the inspection is completed, the second slider 82 is controlled to slide, thereby controlling the fan 100 connected to the second connecting member 83 to move away from the inspection station.

[0131] According to some embodiments of the present application, see Figure 1 and Figure 2 The second moving assembly 80 also includes a second driving member 84, which is connected to the workbench 10, and the second driving member 84 is connected to the second connecting member 83, and the second driving member 84 is configured to drive the second connecting member 83 to move along the second direction Y.

[0132] Exemplarily, the second driving member 84 may be a cylinder, or the second driving member 84 may be a motor.

[0133] In the embodiment of the present application, a second driving member 84 is provided to drive the second connecting member 83 to move along the second direction Y, which is more labor-saving.

[0134] According to some embodiments of the present application, Figure 6 This is an exploded schematic diagram of the cooperation between a second connecting member and a fan provided in an embodiment of the present application. Figure 6 The second connecting member 83 includes a connecting block 831 and a limiting baffle 832 , the connecting block 831 is connected to the second slider 82 , and the limiting baffle 832 is connected to the connecting block 831 along the second direction Y away from the side of the first moving component 20 .

[0135] In an embodiment of the present application, the connecting block 831 is connected to the second slider 82, so that the entire second connecting member 83 can move with the second slider 82. The fan 100 is placed on the connecting block 831, and the second slider 82 moves. Under the action of inertia, the fan 100 may fall from the side of the connecting block 831 away from the first movable component 20 along the second direction Y. The limiting baffle 832 can resist the fan 100 and prevent the fan 100 from falling.

[0136] At the same time, when testing the fan 100, the limit baffle 832 can be used to press the fan 100 against the air volume detection component 30 or the air tightness detection component 40 to improve the stability of the fan 100. At the same time, there is no need to set components such as screws to connect the fan 100 and the second connecting member 83, which is conducive to improving the assembly and disassembly efficiency of the fan 100 and reducing the problem of wear of the fan 100 caused by the installation of screws.

[0137] According to some embodiments of the present application, see Figure 6 The second connecting member 83 includes two limiting baffles 832 , one of the two limiting baffles 832 extends along the first direction X, and the other of the two limiting baffles 832 extends along the third direction Z.

[0138] Exemplarily, the two limit baffles 832 are in an "L" shape.

[0139] In the embodiment of the present application, the two limiting baffles 832 can limit the fan 100 from two sides of the fan 100, and the limiting effect is better.

[0140] See also Figure 6 The limiting baffle 832 itself is also in an "L" shape, so that the limiting baffle 832 can limit the fan 100 on one side of the fan 100 along the first direction X. At the same time, the fan 100 is placed in the "L"-shaped positioning groove formed by the two limiting baffles 832 to achieve the positioning of the fan.

[0141] In some embodiments of the present application, the first movable component 20, the air volume detection component 30, the air tightness detection component 40, the insulation detection component 50, the positioning sensor 70 and the second movable component 80 are all communicatively connected with the controller 90. The controller 90 can control the first movable component 20 and the second movable component 80 to move or stop moving. The controller 90 can control the air volume detection component 30, the air tightness detection component 40 and the insulation detection component 50 to work or stop working.

[0142] Exemplarily, the controller 90 can also be connected to a device such as a barcode scanner, and the barcode scanner can be used to scan and identify the fan 100. After all items of the fan 100 are detected, the recorded data can correspond one by one.

[0143] When the wind turbine detection device provided in the embodiment of the present application is used to detect the wind turbine 100, the following steps may be included:

[0144] Step 1: Place the fan 100 on the connecting block 831 , and make the limiting baffle 832 abut against the fan 100 .

[0145] Step 2: Control the second moving assembly 80 to move along the second direction Y, so that the fan 100 moves to the detection station.

[0146] Step three: control the first moving assembly 20 to move along the first direction X, so that the air volume detection assembly 30 is opposite to the fan 100 , and the fan 100 covers the air inlet 311 , and the air outlet of the fan 100 is connected to the air inlet 311 .

[0147] Step 4: Control the rotary motor 53 to rotate so that the insulation detection element 52 contacts the fan 100 .

[0148] Step 5: Start the fan 100, control the air volume detection component 30 and the insulation detection component 50 to work, and perform air volume and insulation detection on the fan 100 respectively.

[0149] Step 6: Control the air volume detection component 30 and the insulation detection component 50 to stop working, and turn off the fan 100.

[0150] Step 7: Control the first moving assembly 20 to move along the first direction X, so that the airtightness detection assembly 40 is opposite to the fan 100, and the fan 100 covers the vent 411, the air pump 43 extracts the gas in the second cavity 412, and the pressure sensor 42 detects the initial pressure.

[0151] Step 8: After the fan 100 is left stationary for a period of time and the pressure in the second cavity 412 is stabilized, the pressure sensor 42 detects the final pressure.

[0152] Step nine: After the fan 100 is inspected, the rotary motor 53 is controlled to rotate so that the insulation inspection element 52 is offset from the fan 100, and the second moving assembly 80 is controlled to move along the second direction Y so that the fan 100 is away from the inspection station.
