Description

Technical Field

[0001] This invention relates to the field of ship oil monitoring equipment technology, and in particular to a fault diagnosis device for ship oil monitoring. Background Technology

[0002] Marine fluid monitoring refers to the process of monitoring and analyzing various fluids on a ship, such as lubricating oil, fuel oil, and hydraulic oil, to ensure the normal operation and safety of ship equipment. Marine fluid monitoring is a crucial aspect of ship operation and maintenance. Through scientific monitoring and analysis, the normal operation of ship equipment can be ensured, equipment lifespan extended, and the safety and reliability of the ship improved. Fault diagnosis devices are required during marine fluid monitoring.

[0003] In related technologies, mobile fault diagnosis devices for ship oil monitoring typically consist of a testing box containing sensors, a microcontroller, and other monitoring and analysis devices. The testing box has an oil connection port on top and casters for movement underneath. However, the harsh operating conditions of a ship while in motion make these mobile fault diagnosis devices prone to slipping on the ground, leading to inaccurate oil monitoring. Furthermore, the lack of a cooling system can easily shorten the lifespan of internal components.

[0004] To overcome the aforementioned shortcomings, patent document CN212843683U discloses a fault diagnosis device for ship oil monitoring. Horizontal plates are fixedly connected to the outer walls of both sides of the detection box. A screw is threaded into the interior of each horizontal plate. A turntable is fixedly connected to the upper surface of the screw, and a pressure plate is fixedly connected to the bottom end of the screw. An anti-slip pad is fixedly connected to the lower surface of the pressure plate. In use, rotating the turntable causes the screw to rotate. The screw is threaded into the horizontal plate, pushing the pressure plate downwards. The pressure plate then pushes the anti-slip pad to the ground, thus securing the fault diagnosis device.

[0005] The aforementioned fault diagnosis device also discloses that an installation slot is provided inside the detection box, and through slots are provided on both outer walls of the installation slot. An exhaust fan is fixedly connected inside the installation slot, which can draw out the heat inside the installation slot to achieve heat dissipation for the fault diagnosis device.

[0006] However, the above-mentioned fault diagnosis device still has the following drawbacks:

[0007] 1. When fixing the device, the turntable needs to be manually rotated to make the pressure plate and anti-slip pad slide down. Manual rotation is quite troublesome.

[0008] 2. The through channel connects the inside and outside of the test box. When connecting the ship's oil pipeline to the connector, oil may splash and spill into the through channel, contaminating the electrical components of the test box. In severe cases, this may lead to short circuits or fires.

[0009] 3. When dissipating heat, it is not possible to filter external dust. Dust can easily enter the device through the heat dissipation window. A large amount of dust falling into the device will affect the use of the internal electrical components. Summary of the Invention

[0010] In view of the above problems, the present invention is proposed to provide a fault diagnosis device for ship oil monitoring that overcomes or at least partially solves the above problems, aiming to achieve automatic anti-slip fixation of the device and improve user experience.

[0011] A further objective of this invention is to protect the electrical components inside the testing box of the fault diagnosis device from oil splashing and spilling into the testing box.

[0012] A further objective of this invention is to protect the heat dissipation window to prevent dust and foreign objects from entering the testing chamber.

[0013] Specifically, the present invention provides the following technical solution:

[0014] A fault diagnosis device for monitoring marine oil levels includes a base plate, an anti-slip seat, and a drive mechanism.

[0015] The base plate is horizontally positioned, and multiple casters are provided on the bottom surface of the base plate. A testing box for monitoring ship oil levels is fixedly installed on the base plate.

[0016] The anti-slip seat is horizontally positioned, and on the horizontal projection plane, the outer contour edge of the anti-slip seat is located outside all the casters.

[0017] The drive mechanism includes a drive shaft and a linkage mechanism. The drive shaft is rotatably connected to the base plate about a horizontal axis, and a motor is driven to the drive shaft. One end of the linkage mechanism is driven to the drive shaft, and the other end is hinged to the anti-slip seat about a horizontal axis, so that when the drive shaft rotates, it drives the anti-slip seat to move downward, and at least makes the bottom end of the anti-slip seat lower than the bottom end of the caster.

[0018] Optionally, the drive shaft includes two threaded segments spaced apart axially and arranged opposite to each other, with the two threaded segments having opposite directions of rotation.

[0019] The linkage mechanism includes two sliders and two connecting rods. Each slider is threadedly connected to a corresponding threaded segment. One end of each connecting rod is hinged to a corresponding slider about a horizontal axis, and the other end of each connecting rod is hinged to the anti-slip seat about a horizontal axis.

[0020] Optionally, the drive shafts are two parallel shafts spaced apart along the width of the detection box. The two drive shafts are connected synchronously via a sprocket and chain mechanism.

[0021] The linkage mechanism consists of two links corresponding to the two drive shafts.

[0022] Optionally, the fault diagnosis device further includes a detection connector, a flip cover, and a transmission mechanism.

[0023] The detection connector is disposed within the upper opening of the detection box. The flip cover is rotatably disposed over the upper opening about a horizontally arranged flipping shaft. The transmission mechanism is configured to drive the flipping shaft to rotate when the drive shaft rotates, thereby causing the flip cover to flip and open the upper opening.

[0024] Optionally, the drive shaft extends along the length of the detection box. A first bevel gear is coaxially fixedly connected to the drive shaft. A second bevel gear is coaxially fixedly connected to one end of the flip shaft.

[0025] The transmission mechanism includes a rotating rod, a third bevel gear, and a fourth bevel gear.

[0026] The rotating rod is rotatably connected to the detection box about a vertical axis. The third bevel gear is coaxially fixedly connected to the lower end of the rotating rod, and the third bevel gear is perpendicularly meshed with the first bevel gear. The fourth bevel gear is coaxially fixedly connected to the upper end of the rotating rod, and the fourth bevel gear is perpendicularly meshed with the second bevel gear.

[0027] Optionally, the drive shaft extends along the length of the detection box. The drive shaft also includes a first worm gear section. A second worm wheel is coaxially and fixedly connected to one end of the tilting shaft.

[0028] The transmission mechanism includes a rotating rod and a first worm gear coaxially fixedly connected to the bottom end of the rotating rod.

[0029] The rotating rod is rotatably connected to the detection box about a vertical axis. A second worm section is provided at the upper end of the rotating rod, and the second worm section meshes with a second worm wheel. The first worm wheel meshes with the first worm section.

[0030] Optionally, the fault diagnosis device further includes two heat dissipation windows, which are respectively disposed on two opposite sides of the detection box along its length.

[0031] The flip cover consists of two flaps that open in opposite directions. Both flip shafts extend along the width of the detection box and are rotatably connected to opposite sides of the upper opening along the length of the detection box.

[0032] The first worm gear segments are two that are spaced apart and opposite to each other along the length of the detection box, and the two first worm gear segments have opposite rotation directions.

[0033] The transmission mechanism consists of two spaced-apart and oppositely arranged along the length of the detection box. A transmission connection is formed between a first worm gear segment and a flip shaft on the same side of the length of the detection box. When the drive shaft rotates, the two first worm gear segments and the two transmission mechanisms cause both flip covers to flip outward and open, and each covers the upper side of the heat dissipation window on the corresponding side.

[0034] Optionally, the fault diagnosis device further includes a heat dissipation window, which is disposed on a first side at one end of the test box along its length.

[0035] The flipping shaft is rotatably connected to one edge of the upper opening near the first side.

[0036] The flipping axis is parallel to the first side surface, and the distance between the flipping axis and the first side surface is less than the length of the flip cover along the length direction of the detection box. The transmission mechanism is configured to drive the flip cover to flip 135°-225° so that it covers the upper side of the heat dissipation window when the flip cover is flipped open.

[0037] Optionally, it also includes a vertically arranged heat dissipation frame and a dustproof mesh located within the heat dissipation frame. The heat dissipation frame is detachably mounted on the heat dissipation window via a snap-fit ​​connection mechanism.

[0038] The snap-fit ​​connection mechanism includes a slide, a locking block, an elastic element, and a locking groove.

[0039] The slide groove is horizontally disposed on one or both sides of the lateral edge of the heat dissipation window. The locking block is slidably connected within the slide groove. The elastic element is configured to cause the locking block to slide along the slide groove toward the heat dissipation window. The locking slot is disposed on the edge of the heat dissipation frame facing the locking block, so that when the heat dissipation frame covers the heat dissipation window, the elastic element causes the locking block to slide along the slide groove and insert into the locking slot.

[0040] Optionally, the anti-slip base includes an anti-slip support plate and clearance holes on the anti-slip support plate corresponding to each of the casters. An anti-slip pad is provided on the bottom surface of the anti-slip support plate.

[0041] In the fault diagnosis device of this invention, an anti-slip seat driven by a drive mechanism is provided on the lower side of the detection box. During use, the control motor drives the drive shaft and linkage mechanism, causing the anti-slip seat to extend downward relative to the base plate. After contacting the ground, the anti-slip seat continues to extend downward relative to the base plate, lifting the detection box upward. At this time, the fault diagnosis device is supported by the anti-slip seat. Compared with the prior art, this chassis positioning operation can be automated, eliminating the need for manual operation and improving the user experience. On the other hand, on the horizontal projection plane, the outer contour edge of the anti-slip seat is located outside all casters, giving the anti-slip seat sufficient anti-slip performance and stability to cope with the poor sailing conditions of ships and prevent the fault diagnosis device from slipping.

[0042] Furthermore, the fault diagnosis device of the present invention has a flip cover at the upper opening of the test box, which can cover the electrical components inside the test box and prevent dust, foreign objects, etc. from entering. On the other hand, by setting a transmission mechanism linked to the drive shaft in the flip cover, during use, while the drive shaft drives the anti-slip seat to extend downward to support the fault diagnosis device, the flip cover flips open the upper opening of the test box, without affecting the user's normal use of the fault diagnosis device.

[0043] Furthermore, in the fault diagnosis device of the present invention, heat dissipation windows are arranged on two opposite sides of the test box, and two flip covers are arranged corresponding to the two heat dissipation windows. When the flip covers are flipped open, they will cover the upper side of the corresponding heat dissipation windows, which can prevent oil above the heat dissipation windows from splashing and dripping into the heat dissipation windows, and then entering the test box and contaminating the electrical components.

[0044] Furthermore, the fault diagnosis device of the present invention includes a detachable heat dissipation frame and a dustproof screen at the heat dissipation window. The dustproof screen prevents dust and foreign objects from entering the test chamber through the heat dissipation window. On the other hand, the heat dissipation frame and dustproof screen can be easily removed from the heat dissipation window for easy cleaning of dust and foreign objects on the screen, and the cleaned heat dissipation frame and dustproof screen can be easily installed back onto the heat dissipation window. This ensures that the heat dissipation channel of the heat dissipation window remains unobstructed, allowing heat from electrical components to dissipate promptly and preventing any impact on the service life of the fault diagnosis device.

[0062] Figure 1 This is a schematic structural diagram of a fault diagnosis device for ship oil monitoring according to an embodiment of the present invention, and in conjunction with... Figure 2-8 The present invention provides a fault diagnosis device for monitoring marine oil, the fault diagnosis device including a base plate 100, an anti-slip seat 400 and a drive mechanism 500.

[0063] The base plate 100 is set horizontally, and multiple casters 200 are set on the bottom surface of the base plate 100. A detection box 300 for monitoring ship oil is fixedly installed on the base plate 100.

[0064] The anti-slip seat 400 is set horizontally, and on the horizontal projection plane, the outer contour edge of the anti-slip seat 400 is outside all the casters 200.

[0065] The drive mechanism 500 includes a drive shaft 510 and a linkage mechanism 520. The drive shaft 510 is rotatably connected to the base plate 100 about a horizontal axis, and a motor 530 is driven to the drive shaft 510. One end of the linkage mechanism 520 is driven to the drive shaft 510, and the other end is hinged to the anti-slip seat 400 about a horizontal axis, so that when the drive shaft 510 rotates, it drives the anti-slip seat 400 to move downward, and at least makes the bottom end of the anti-slip seat 400 lower than the bottom end of the caster 200.

[0066] In this embodiment, the drive mechanism 500 is used to drive the anti-slip seat 400 to extend or retract relative to the base plate 100. When moving the fault diagnosis device, the anti-slip seat 400 retracts to the underside of the base plate 100 and is located above the bottom end of the caster 200, without affecting the caster 200's ability to move the fault diagnosis device.

[0067] When the fault diagnosis device is moved into position and preparations for fault diagnosis are being made, the motor 530 can be started, electrically driving the drive shaft 510 to rotate. The rotating shaft then drives the linkage mechanism 520 to move, causing the anti-slip seat 400 to extend downward relative to the base plate 100. After the bottom surface of the anti-slip seat 400 contacts the ground, the anti-slip seat 400 continues to extend downward relative to the base plate 100, lifting the base plate 100 and the detection box 300 upward. At this time, the fault diagnosis device is supported by the anti-slip seat 400.

[0068] The bottom of the anti-slip seat 400 can be a horizontal surface to contact the ground. On the horizontal projection surface, the horizontal bottom surface of the anti-slip seat 400 covers all casters 200 to increase the contact area with the ground, thereby stably supporting the fault diagnosis device. This gives the anti-slip seat 400 sufficient anti-slip performance and stability to cope with the poor sailing conditions of the ship and prevent the fault diagnosis device from slipping.

[0069] The bottom of the anti-slip base 400 can also be multiple support columns, with the bottom of the support columns in contact with the ground to stably support the fault diagnosis device.

[0070] Of course, in order to improve the anti-slip ability of the anti-slip seat 400, anti-slip pads 430 can also be set on the horizontal bottom surface of the anti-slip seat 400 or at the lower end of multiple support columns to increase its friction with the ground.

[0071] In this embodiment, the drive shaft 510 is horizontally positioned and located below the base plate 100 to avoid obstructing the normal operation of the detection box 300. The drive shaft 510 can be positioned along the length or width of the detection box 300, or it can be at a preset angle to the length of the detection box 300, as long as it can drive the anti-slip seat 400 to move vertically via the linkage mechanism 520. The linkage mechanism 520 can be a single-linkage mechanism or a multi-linkage mechanism; no limitation is made here.

[0072] The motor 530 can be coaxially and fixedly connected to the drive shaft 510 to directly drive the drive shaft 510 to rotate, or it can drive the drive shaft 510 to rotate through a transmission device.

[0073] In this embodiment, the fault diagnosis device can be equipped with a control switch. When the user moves the fault diagnosis device into place, the control switch is turned on, the motor 530 starts, and the anti-slip seat 400 extends downward.

[0074] Compared with existing technologies, the fault diagnosis device of the present invention can operate automatically, realize the fixation of the fault diagnosis device, reduce manual operation, and improve user experience.

[0075] In some embodiments of the fault diagnosis device of the present invention, such as Figure 5-7 As shown, the drive shaft 510 includes two threaded segments 511 that are spaced apart axially and arranged opposite to each other, and the two threaded segments 511 have opposite directions of rotation.

[0076] The linkage mechanism 520 includes two sliders 521 and two connecting rods 522. Each slider 521 is threadedly connected to a corresponding threaded section 511. One end of each connecting rod 522 is hinged to a corresponding slider 521 about a horizontal axis, and the other end of each connecting rod 522 is hinged to an anti-slip seat 400 about a horizontal axis.

[0077] In this embodiment, the drive shaft 510 and the slider 521 form a screw drive mechanism, and the linkage mechanism 520 is a multi-link mechanism. When the drive shaft 510 rotates, the two oppositely arranged threaded segments 511 drive the two sliders 521 to slide towards or away from each other. The two connecting rods 522 can be of the same specification, with the upper end of the connecting rod 522 hinged to the lower end of the slider 521 and the lower end of the connecting rod 522 hinged to the upper end of the anti-slip seat 400. A guide rail for limiting the slider 521 can be provided on the base plate 100.

[0078] For example, when the drive shaft 510 rotates clockwise, the two sliders 521 slide towards each other, causing the two connecting rods 522 to rotate relative to each other, thereby pushing the anti-slip seat 400 to extend downward relative to the base plate 100.

[0079] During operation, the anti-slip seat 400 provides more stable support for the base plate 100 and the detection box 300 through at least two connecting rods 522.

[0080] Preferably, the two connecting rods 522 and the two hinge axes of the anti-slip seat 400 are symmetrically arranged relative to the center of the detection box 300 along its length direction. A preset distance exists between the two connecting rods 522 and the two hinge axes of the anti-slip seat 400, and this preset distance is greater than 2 / 3 of the length of the detection box 300. This provides further stable support for the detection box 300 during operation.

[0081] Specifically, by rationally setting the transmission ratio of the screw sliding mechanism, the ratio of the rotational speed of the drive shaft 510 to the extension speed of the anti-slip seat 400 can be rationally set. On the one hand, a smaller motor 530 can be selected to achieve a larger pushing force on the anti-slip seat 400, thereby smoothly lifting the base plate 100 and the detection box 300 after the anti-slip seat 400 touches the ground. On the other hand, the output speed of the motor 530 can be reduced through the screw sliding mechanism, so that the motor 530 does not need an additional reducer and can be coaxially fixedly connected to the drive shaft 510.

[0082] In some embodiments of the fault diagnosis device of the present invention, such as Figure 5-6 As shown, there are two drive shafts 510 arranged parallel to each other and spaced apart along the width direction of the detection box 300. The two drive shafts 510 are connected synchronously through a sprocket and chain mechanism 540.

[0083] The linkage mechanism 520 consists of two parts corresponding to the two drive shafts 510.

[0084] In this embodiment, the drive shaft 510 is arranged along the length direction of the detection box 300, and there are two drive shafts 510, respectively arranged at opposite ends in the width direction of the detection box 300. This arrangement ensures that the anti-slip seat 400 has at least four connecting rods 522 for support, which can further improve the stability of the anti-slip seat 400 in supporting the base plate 100 and the detection box 300, and also improve the support strength.

[0085] For example, sprockets can be installed at one end of the two drive shafts 510 on the same side of the length direction of the detection box 300, and the two sprockets can achieve synchronous transmission through a chain (not shown in the figure). In this way, a single motor 530 can be used to drive the two drive shafts 510 to rotate synchronously, thereby driving the four connecting rods 522 to move synchronously, ensuring that the anti-slip seat 400 extends downward in the vertical direction.

[0086] Preferably, the two drive shafts 510 are arranged symmetrically with respect to the center of the detection box 300 in the width direction, and the distance between the two drive shafts 510 is greater than 2 / 3 of the width of the detection box 300. In this way, the detection box 300 can be more stably supported during operation.

[0087] In some embodiments of the fault diagnosis device of the present invention, such as Figure 2-6 As shown, the fault diagnosis device also includes a detection connector 340, a flip cover 610, and a transmission mechanism 700.

[0088] The detection connector 340 is disposed within the upper opening 310 of the detection box 300. The flip cover 610 is rotatably disposed over the upper opening 310 about a horizontally arranged flipping shaft 620. The transmission mechanism 700 is configured to drive the flipping shaft 620 to rotate when the drive shaft 510 rotates, thereby causing the flip cover 610 to flip and open the upper opening 310.

[0089] In this embodiment, the detection connector 340 is disposed within the upper opening 310 for connecting or transmitting fluids, electricity, data, etc. A flip cover 610 is provided in the upper opening 310 of the detection box 300 to cover the electrical components inside the detection box 300 and prevent dust, foreign objects, etc. from entering. A transmission mechanism 700 linked to the drive shaft 510 is provided in the flip cover 610. The transmission mechanism 700 can be a linkage device, gear transmission device, chain transmission device, rope transmission device, worm gear device, etc., as long as it can form a transmission connection between the drive shaft 510 and the flip cover 610.

[0090] In use, when the user moves the fault diagnosis device into position, they turn on the control switch, starting the motor 530 and driving the anti-slip base 400 to extend downwards, stably supporting the detection box 300. Simultaneously, the drive shaft 510 drives the transmission mechanism 700, causing the flip cover 610 to flip open the upper opening 310 of the detection box 300, facilitating the user to connect the detection connector 340 to the corresponding equipment on the ship, thus preparing for fault diagnosis. This technical solution can significantly save the user's operation and preparation time, improving the efficiency of fault diagnosis.

[0091] In some embodiments of the fault diagnosis device of the present invention, the drive shaft 510 extends along the length of the detection box 300. A first bevel gear is coaxially fixedly connected to the drive shaft 510. A second bevel gear is coaxially fixedly connected to one end of the flip shaft 620.

[0092] The transmission mechanism 700 includes a rotating rod 710, a third bevel gear, and a fourth bevel gear.

[0093] The rotating rod 710 is rotatably connected to the detection box 300 around a vertical axis. The third bevel gear is coaxially fixedly connected to the lower end of the rotating rod 710, and the third bevel gear is perpendicularly meshed with the first bevel gear. The fourth bevel gear is coaxially fixedly connected to the upper end of the rotating rod 710, and the fourth bevel gear is perpendicularly meshed with the second bevel gear.

[0094] In this embodiment, the transmission mechanism 700 is a bevel gear device. By setting bevel gears at both ends of the drive shaft 510, the rotating rod 710, and the flip shaft 620, the power of the drive shaft 510 can be transmitted to the flip shaft 620, thereby driving the flip cover 610 to flip open.

[0095] In some embodiments of the fault diagnosis device of the present invention, such as Figure 5-7 As shown, the drive shaft 510 extends along the length of the detection box 300. The drive shaft 510 also includes a first worm gear section 512. A second worm wheel 740 is coaxially and fixedly connected to one end of the tilting shaft 620.

[0096] The transmission mechanism 700 includes a rotating rod 710 and a first worm gear 730 coaxially fixedly connected to the bottom end of the rotating rod 710.

[0097] The rotating rod 710 is rotatably connected to the detection box 300 around a vertical axis. A second worm section 720 is provided at the upper end of the rotating rod 710, and the second worm section 720 is meshed with a second worm wheel 740. The first worm wheel 730 is meshed with the first worm section 512.

[0098] In this embodiment, the transmission mechanism 700 is a worm gear device. By setting worm gears on both the drive shaft 510 and the flip shaft 620, and setting worms at both ends of the rotating rod 710, the power of the drive shaft 510 can be transmitted to the flip shaft 620, thereby driving the flip cover 610 to flip open.

[0099] Because the worm gear mechanism can have a large reduction ratio, by properly configuring the worm gear and worm, the flip shaft 620 can rotate at the required speed. Thus, when the anti-slip seat 400 extends downwards to its final position, the flip cover 610 can simultaneously flip into place.

[0100] In some embodiments of the fault diagnosis device of the present invention, such as Figure 2-6 As shown, the fault diagnosis device also includes two heat dissipation windows 320, which are respectively set on two opposite sides of the test box 300 along its length.

[0101] The flip cover 610 consists of two flip-tops, and both flip shafts 620 extend along the width direction of the detection box 300. The two flip shafts 620 are rotatably connected to the opposite two edges of the upper opening 310 along the length direction of the detection box 300.

[0102] The first worm gear segments 512 are two that are spaced apart and opposite to each other along the length of the detection box 300, and the two first worm gear segments 512 have opposite rotation directions.

[0103] Two transmission mechanisms 700 are arranged at intervals and opposite to each other along the length direction of the detection box 300. They form a transmission connection between a first worm segment 512 and a flip shaft 620 on the same side of the length direction of the detection box 300, so that when the drive shaft 510 rotates, the two first worm segments 512 and the two transmission mechanisms 700 cause the two flip covers 610 to flip outward and open, and each covers the upper side of the heat dissipation window 320 on the corresponding side.

[0104] In this embodiment, there are two heat dissipation windows 320 arranged opposite each other along the length of the detection box 300. On the one hand, this can increase the heat dissipation area, and on the other hand, it can form airflow convection to improve heat dissipation efficiency.

[0105] The heat dissipation window 320 has a channel that connects to the inside of the detection box 300. During operation, oil may splash or spill into the heat dissipation window 320 and then enter the inside of the detection box 300, contaminating the electrical components.

[0106] To solve this problem, in this embodiment, two flip covers 610 are configured to correspond to the heat dissipation windows 320. The flipping axis 620 of the flip cover 610 is located above the heat dissipation windows 320 and is parallel to the heat dissipation windows 320. In this way, when the flip cover 610 is flipped open, it will cover the upper side of the corresponding heat dissipation window 320, which can prevent oil above the heat dissipation window 320 from splashing and dripping into the heat dissipation window 320 and then entering the inside of the detection box 300, contaminating the electrical components.

[0107] In this embodiment, the flip cover 610 provides dual protection. When closed, it protects the electrical components inside the upper opening 310 of the detection box 300. When open, it protects the heat dissipation window 320.

[0108] In some embodiments of the fault diagnosis device of the present invention, such as Figure 2-6 As shown, the fault diagnosis device also includes a heat dissipation window 320, which is disposed on the first side 330 at one end of the length direction of the test box 300.

[0109] The flip shaft 620 is rotatably connected to the edge of the upper opening 310 near the first side 330.

[0110] The flipping shaft 620 is parallel to the first side surface 330, and the distance between the flipping shaft 620 and the first side surface 330 is less than the length of the flip cover 610 along the length direction of the detection box 300. The transmission mechanism 700 is configured to drive the flip cover 610 to flip 135°-225° so that when the flip cover 610 is flipped open, it covers the upper side of the heat dissipation window 320.

[0111] In this embodiment, the flip cover 610 is correspondingly arranged with the heat dissipation window 320, and the flip cover 610 can be flipped outward by 135°-225°. Preferably, the flip cover 610 is flipped outward by 180°, so that when it is flipped open to the fullest extent, it can cover the heat dissipation window 320 from the top to the maximum extent, without blocking the heat dissipation channel of the heat dissipation window 320 and affecting the heat dissipation efficiency of the heat dissipation window 320.

[0112] In some embodiments of the fault diagnosis device of the present invention, such as Figure 8 As shown, it also includes a vertically arranged heat dissipation frame 810 and a dustproof mesh 820 inside the heat dissipation frame 810. The heat dissipation frame 810 is detachably mounted on the heat dissipation window 320 via a snap-fit ​​connection mechanism 900.

[0113] The snap-fit ​​connection mechanism 900 includes a slide 910, a snap block 920, an elastic element 930, and a snap groove 940.

[0114] A slide groove 910 is horizontally disposed on one or both sides of the lateral edge of the heat dissipation window 320. A locking block 920 is slidably connected within the slide groove 910. An elastic element 930 is configured to cause the locking block 920 to slide along the slide groove 910 toward the heat dissipation window 320. A slot 940 is disposed on the edge of the heat dissipation frame 810 facing the locking block 920, so that when the heat dissipation frame 810 covers the heat dissipation window 320, the elastic element 930 causes the locking block 920 to slide along the slide groove 910 and insert into the slot 940.

[0115] In this embodiment, two sliding grooves 910 can be arranged opposite each other on the same side of the heat dissipation window 320. For example, two sliding grooves 910 are arranged vertically at intervals on the right side of the heat dissipation window 320, and both sliding grooves 910 extend horizontally. The upper and lower ends of the locking block 920 are inserted into the sliding grooves 910. The locking block 920 can slide left and right. When sliding to the left, the left end of the locking block 920 inserts into the locking slot 940 on the right side of the heat dissipation frame 810, thereby fixing and supporting the heat dissipation frame 810. When the locking block 920 slides to the right, the left end of the locking block 920 disengages from the locking slot 940, allowing the heat dissipation frame 810 to be removed.

[0116] Preferably, the locking block 920 may be equipped with a handle, and a compression spring may be provided on the connecting arm of the handle. When the user pulls the handle, the locking block 920 slides, allowing for easy disassembly and assembly of the heat sink frame 810.

[0117] Preferably, a snap-fit ​​connection mechanism 900 is provided on both the left and right sides of the heat dissipation window 320.

[0118] In this embodiment of the fault diagnosis device, the dustproof mesh 820 prevents dust and foreign objects from entering the detection box 300 through the heat dissipation window 320. By providing a snap-fit ​​connection mechanism 900, the heat dissipation frame 810 and the dustproof mesh 820 can be easily removed from the heat dissipation window 320 for easy cleaning of dust and foreign objects on the dustproof mesh 820, and the cleaned heat dissipation frame 810 and dustproof mesh 820 can be easily installed back onto the heat dissipation window 320. This ensures that the heat dissipation channel of the heat dissipation window 320 remains unobstructed, allowing heat from electrical components to dissipate promptly and preventing any impact on the service life of the fault diagnosis device.

[0119] In some embodiments of the fault diagnosis device of the present invention, such as Figure 4-7 As shown, the anti-slip base 400 includes an anti-slip support plate 410 and clearance holes 420 on the anti-slip support plate 410 corresponding to each caster 200. An anti-slip pad 430 is provided on the bottom surface of the anti-slip support plate 410.

[0120] The anti-slip mat 430 can increase the friction between the anti-slip seat 400 and the ground, thereby stably supporting the fault diagnosis device, preventing the fault diagnosis device from moving or shaking, and meeting the requirements of ship operating conditions.

[0121] Preferably, there are four casters 200, which are respectively located at the four corners of the base plate 100. Four clearance holes 420 are correspondingly provided on the anti-slip seat 400.

[0122] In some embodiments of the fault diagnosis device of the present invention, such as Figure 1 As shown, a display screen 350 is also provided on one side of the test box 300 to display fault diagnosis data and perform human-machine interaction.

[0123] In some embodiments of the fault diagnosis device of the present invention, a second heat dissipation window 320 is also provided on the base plate 100. During operation, cold air can enter the detection chamber 300 upward through the second heat dissipation window 320, and after heat exchange, it flows out through the heat dissipation window 320 located on the side of the detection chamber 300. In this way, the convection velocity can be increased and the heat dissipation efficiency can be improved.

[0124] When not in use, the anti-slip seat 400 retracts upwards, covering the second heat dissipation window 320 on the base plate 100 on its lower side to prevent foreign objects from entering. When in use, the anti-slip seat 400 extends downwards, widening the gap between itself and the base plate 100, thereby opening the second heat dissipation window 320 and forming an air intake channel for the second heat dissipation window 320.

[0125] While this invention provides several exemplary embodiments, many other variations or modifications consistent with the principles of this invention can be directly determined or derived from the disclosure of this invention without departing from its spirit and scope. Therefore, the scope of this invention should be understood and recognized as covering all such other variations or modifications.
