Description

Technical Field

[0001] This utility model relates to the field of gateway technology, and in particular to an edge computing gateway for fault early warning of industrial IoT devices. Background Technology

[0002] Edge computing gateway technology for industrial IoT device fault early warning is an inevitable product of industrial digital transformation and information technology evolution. Its core driving factors include the limitations of traditional architectures, the surge in real-time requirements, data security and compliance pressures, and the impetus of technological integration and innovation.

[0003] The existing gateways typically have at least two mounting and positioning structures for the filter components used for ventilation, heat dissipation, and debris blocking to ensure the stability of the filter components. However, the lack of a transmission connection mechanism between the two mounting and positioning structures means that the filter components cannot be unlocked simultaneously in one operation. This results in the filter components needing to be unlocked step by step by operating the two mounting and positioning structures sequentially, which is quite cumbersome and inconvenient. It also makes it difficult to disassemble the filter components and expose the electrical components inside the gateway housing for cleaning. Utility Model Content

[0004] In view of this, the present invention provides an edge computing gateway for fault early warning of industrial IoT equipment, in order to solve the problem that the unlocking operation of the filter assembly requires step-by-step operation of two installation and positioning structures, which is relatively troublesome and inconvenient to disassemble the filter assembly and expose the electrical components inside the gateway housing for cleaning.

[0005] The technical solution proposed by this utility model is as follows: an edge computing gateway for fault early warning of industrial Internet of Things equipment, specifically including a gateway body. A square heat dissipation groove is formed through the top wall of the outer shell of the gateway body. A detachable filter holding frame is inserted inside the square heat dissipation groove. An I-shaped retainer is fixedly connected to the bottom opening of the filter holding frame. Two U-shaped insert frames are symmetrically slidably installed at the top of the I-shaped retainer in the form of spring push. The two short side shafts of the U-shaped insert frames pass through the side wall of the filter holding frame and are inserted into the side wall of the square heat dissipation groove. A torsion drive component is rotatably installed at the center position of the I-shaped retainer. The torsion drive component is composed of a centering shaft and two L-shaped transmission rods welded together. Two connecting rods are symmetrically rotatably connected between the two L-shaped transmission rods and the two U-shaped insert frames. Multiple ventilation channels are formed between the I-shaped retainer and the four sides of the filter holding frame. Metal ventilation filters are installed in the ventilation channels.

[0006] Furthermore, four mounting lugs are symmetrically welded to the top side of the four ends of the I-shaped retainer, and the short side shaft of the U-shaped insert frame slides through and engages with the mounting lugs. A limit ring is fixedly fitted on the short side shaft.

[0007] Furthermore, the limiting ring is located between the mounting ear block and the side wall of the filter screen holding frame, and abuts against the side wall of the filter screen holding frame.

[0008] Furthermore, the spring that pushes the U-shaped insert frame is fitted onto the short side shaft of the U-shaped insert frame and is compressed and clamped between the limiting ring and the mounting lug.

[0009] Furthermore, the two ends of the connecting rod are rotatably connected to the vertical part of the L-shaped transmission rod and the middle part of the long side shaft of the U-shaped insert frame, respectively.

[0010] Furthermore, the centering shaft is rotatably assembled through the center position of the I-shaped cage, and a plum blossom-shaped knob is welded to the top of the centering shaft.

[0011] The edge computing gateway for fault early warning of industrial IoT devices provided by this utility model has the following beneficial effects: 1. The metal ventilation filter is installed on the filter retaining frame. The filter retaining frame is detachable, allowing the metal ventilation filter to be removed from the square heat dissipation slot. The metal ventilation filter can then be flipped over to clean the dust on its underside. This facilitates a thorough and effective cleaning and unblocking of the metal ventilation filter. Furthermore, removing the metal ventilation filter and its retaining frame opens the square heat dissipation slot, exposing the electrical components inside the gateway body and making it easier to clean the dust accumulated on their surfaces.

[0012] 2. Two connecting rods, two U-shaped inserts, and a torsion drive unit are connected to form a modified double-crank slider mechanism. Through this mechanism, the forward and reverse rotation of the torsion drive unit can drive the two U-shaped inserts to slide towards or away from each other, engaging or disengaging with the side walls of the square heat dissipation slot. This allows for one-time locking or unlocking of the filter holding frame and the metal ventilation filter. This eliminates the hassle of having to remove the two U-shaped inserts step by step to unlock the filter holding frame and the metal ventilation filter when disassembling them and cleaning the dust from the metal ventilation filter and the electrical components inside the gateway body. This helps improve the disassembly efficiency of the filter holding frame and the metal ventilation filter, and indirectly improves the ease of cleaning the metal ventilation filter and electrical components.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please refer to Figures 1 to 6 Example 1: This embodiment proposes an edge computing gateway for fault early warning of industrial IoT devices, including a gateway body 1. A square heat dissipation slot 102 is formed through the top wall 101 of the outer shell of the gateway body 1. A detachable filter holding frame 2 is inserted inside the square heat dissipation slot 102. An I-shaped retainer 201 is fixedly connected to the bottom opening of the filter holding frame 2. Two U-shaped insert frames 4 are symmetrically slidably installed at the top of the I-shaped retainer 201 by means of spring push. The two short side shafts of the U-shaped insert frames 4 pass through the side wall of the filter holding frame 2 and the square heat dissipation slot 102. The sidewalls of the heat dissipation slot 102 are inserted and fitted; a torsion drive 5 is rotatably installed at the center of the I-shaped retainer 201. The torsion drive 5 is composed of a centering shaft 501 and two symmetrically distributed L-shaped transmission rods 502 welded together. The two L-shaped transmission rods 502 are symmetrically rotatably connected to the two U-shaped insert frames 4 by two connecting rods 402; multiple ventilation channels are formed between the I-shaped retainer 201 and the four sides of the filter screen retainer 2. A metal ventilation filter 3 adapted to its shape is installed in the ventilation channels.

[0019] Implementation 2: This embodiment is based on Implementation 1, but with the following additions: Four mounting lugs 2011 are symmetrically welded to the top side of the four ends of the I-shaped retainer 201. The short side shaft of the U-shaped insert frame 4 is slidably engaged with the mounting lugs 2011. A limiting ring 401 is fixedly mounted on the short side shaft. The limiting ring 401 is located between the mounting lugs 2011 and the side wall of the filter screen retainer 2, and abuts against the side wall of the filter screen retainer 2. A spring that pushes the U-shaped insert frame 4 is mounted on the short side shaft of the U-shaped insert frame 4 and is compressed and clamped between the limiting ring 401 and the mounting lugs 2011.

[0020] Preferably, the two ends of the connecting rod 402 are rotatably connected to the vertical part of the L-shaped transmission rod 502 and the middle part of the long side shaft of the U-shaped insert frame 4, respectively.

[0021] Preferably, the centering shaft 501 and the I-shaped cage 201 are rotated through each other at their center positions, and a plum blossom-shaped knob is welded to the top of the centering shaft 501.

[0022] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: This gateway is compatible with industrial equipment communication protocols and can directly connect to devices such as sensors and PLCs to collect equipment operation data related to faults. The gateway can directly clean, compress, and standardize the collected data locally, filtering out invalid data. After the above preprocessing, the gateway loads a preset fault diagnosis model and uses the preprocessed data to drive the model, performing real-time comparative analysis to determine whether the data meets fault characteristics or exceeds the warning threshold. If it does, a warning message is immediately generated. After completing the above process, the gateway pushes the warning message to the field terminal locally, while only uploading the warning message, abnormal data, and other core data to the cloud, achieving rapid local response and cloud data synchronization. Finally, according to preset rules or instructions, the control commands are converted into a device-recognizable protocol and issued, enabling rapid fault handling and preventing the fault from escalating.

[0023] The metal ventilation filter 3 can block and intercept large-volume debris in the external environment, preventing large debris from entering the gateway body 1 and covering the internal electrical components of the gateway body 1, thus blocking and hindering the normal and effective heat dissipation of the electrical components. The heat generated by the internal electrical components of the gateway body 1 during operation is dissipated to the outside through the metal ventilation filter 3 to achieve heat dissipation and cooling of the electrical components. However, after prolonged use, both the metal ventilation filter 3 and the electrical components will accumulate excessive dust. A large amount of dust on the metal ventilation filter 3 will clog its filter holes, affecting its ventilation and heat dissipation effect. On the other hand, a large amount of dust on the surface of the electrical components will block and hinder the dissipation of its operating heat, which can easily cause high-temperature damage and affect its service life. Therefore, it is necessary to clean and remove dust from the metal ventilation filter 3 and the electrical components regularly.

[0024] The metal ventilation filter 3 is installed on the filter holding frame 2. The filter holding frame 2 is detachable. By removing the filter holding frame 2, the metal ventilation filter 3 can be removed from the square heat dissipation slot 102. The metal ventilation filter 3 can be turned over to clean the dust attached to the bottom of the metal ventilation filter 3. This facilitates a thorough and effective cleaning and unblocking of the metal ventilation filter 3. In addition, by removing the metal ventilation filter 3 and the filter holding frame 2, the square heat dissipation slot 102 can be opened, allowing the electrical components inside the gateway body 1 to be exposed through the open square heat dissipation slot 102, making it convenient to clean the dust attached to their surfaces.

[0025] When the U-shaped insert frame 4 is inserted into the side wall of the square heat dissipation slot 102, the filter holding frame 2 and the metal ventilation filter 3 can be inserted and positioned in the square heat dissipation slot 102. The U-shaped insert frame 4 is held in the inserted and positioned state by the spring on it. The two connecting rods 402, the two U-shaped insert frames 4, and the torsion drive 5 are connected to form a deformed double crank slider mechanism. Through this mechanism, the forward and reverse rotation of the torsion drive 5 can drive the two U-shaped insert frames 4 to slide towards or away from each other, and insert into the side walls of the square heat dissipation slot 102. The filter retaining frame 2 and the metal ventilation filter 3 can be locked or unlocked in one go by merging or detaching them. This eliminates the trouble of having to remove the two U-shaped inserts 4 in steps to unlock the filter retaining frame 2 and the metal ventilation filter 3 when disassembling the filter retaining frame 2 and the metal ventilation filter 3 and cleaning the dust inside the electrical components of the metal ventilation filter 3 and the gateway body 1. This helps to improve the disassembly efficiency of the filter retaining frame 2 and the metal ventilation filter 3, and indirectly improves the convenience of cleaning the dust of the metal ventilation filter 3 and the electrical components.
