Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to a remote control cabinet with good heat dissipation. Background Technology

[0002] A remote control cabinet is an intelligent control system based on Internet of Things (IoT) technology, enabling remote operation and management of equipment through network communication. Its core function is to integrate sensors, actuators, and communication modules to transmit equipment operating data to a cloud platform in real time, allowing users to monitor and issue commands through terminal devices.

[0003] Currently, a Chinese patent discloses a remote control structure for a cleaning machine (authorization announcement number CN222339698U). When it rains, four forward and reverse motors are activated, causing two L-shaped baffles to move on four threaded rods. Since there is an L-shaped baffle on every two threaded rods, the movement stability of the L-shaped baffles is improved. The baffles move downwards a suitable distance, so that the two L-shaped baffles precisely cover the heat dissipation holes on both sides of the control cabinet, preventing rainwater from entering the control cabinet from both sides and affecting the information transmission between internal communication modules, as well as the use effect of sensors and controllers. This improves the operational stability of the cleaning machine and thus enhances the effectiveness of the remote control structure.

[0004] Because the above-mentioned device directly uses an exposed threaded rod to guide the movement of the L-shaped baffle, the threaded rod is easily covered with dust from the outside air and is corroded by wind and rain. This will change the surface structure of the threaded rod, increase the resistance to the movement of the L-shaped baffle, and in severe cases, it may even cause the L-shaped baffle to get stuck with the threaded rod, making it impossible for the L-shaped baffle to rise and fall normally. Utility Model Content

[0005] Therefore, it is necessary to provide a remote control cabinet with better heat dissipation to address the problem that existing remote control cabinets with rainproof and heat dissipation functions are easily interfered with by the external environment, leading to an increased equipment failure rate.

[0006] A remote control cabinet with good heat dissipation includes:

[0007] The cabinet has an air inlet and an air outlet at both ends, and a fan connected to the air inlet is fixedly connected to the vertical inner wall of the cabinet.

[0008] The cabinet has two protective mechanisms, which are fixedly connected to both ends of the cabinet. The opposite ends of the two protective mechanisms are connected to the air inlet and the air outlet, respectively.

[0009] In one embodiment, the protective mechanism near the fan includes an air guide tube fixedly connected to one end of the cabinet, one opening of the air guide tube communicating with an air inlet, the other opening of the air guide tube facing the ground, and a dustproof net embedded inside the other opening of the air guide tube.

[0010] In one embodiment, a threaded groove is provided on the inner side of another opening of the air guide duct, and an external threaded sleeve is threadedly connected to the inner side of the threaded groove. The dustproof net is fixedly connected to the inner side of the external threaded sleeve.

[0011] In one embodiment, an adjustment bracket is fixedly connected to the inner side of the external threaded sleeve, and the adjustment bracket is located below the dustproof net.

[0012] In one embodiment, the horizontal cross-sectional shape of the adjustment frame is cross-shaped, and the corners of the adjustment frame are rounded.

[0013] In one embodiment, a limiting ring is fixedly connected to the outer side of the external threaded sleeve, and the inner diameter of the limiting ring is larger than the inner diameter of the threaded groove.

[0014] In one embodiment, the protective mechanism further includes a sealing assembly comprising a sealing plate and a circular frame. The sealing plate is hinged to the inside of the air duct, and the vertical cross-sectional dimension of the sealing plate is larger than the horizontal cross-sectional dimension of the threaded groove. The circular frame is fixedly connected to the top of the external threaded sleeve, and the top of the circular frame passes through the threaded groove and contacts the sealing plate.

[0015] In one embodiment, a spring sheet that contacts the air duct is fixedly connected to one end of the sealing plate facing away from the circular frame, and the spring sheet is always in a compressed state.

[0016] In one embodiment, a reserved groove is provided on the inner side of the air guide tube, and one end of the spring sheet passes through the interior of the reserved groove.

[0017] Beneficial effects

[0018] The aforementioned remote control cabinet with good heat dissipation adopts an air duct design with the opening facing the ground. This ensures that the heat dissipation airflow can only enter the cabinet from bottom to top and exit the cabinet from top to bottom, effectively blocking rainwater from entering the cabinet and reducing the probability of short circuits in the internal structure of the cabinet due to water. Furthermore, it does not require moving any structure and can also improve the overall protective strength of the protective mechanism.

[0019] The sealing component can simultaneously seal the air duct while the user removes the dustproof screen for maintenance. This prevents outside air from carrying solid impurities into the cabinet, achieving a good sealing and protection effect. After the dustproof screen is reinstalled, the sealing plate is vertically attached to the air duct, allowing the air duct to connect with the outside and achieve normal airflow.

[0032] The following is combined Figures 1-4 This invention describes a remote control cabinet with good heat dissipation performance.

[0033] In one embodiment, a remote control cabinet with good heat dissipation includes:

[0034] The cabinet 100 has an air inlet 110 and an air outlet 120 at its two ends, and a fan 200 connected to the air inlet 110 is fixedly connected to the vertical inner wall of the cabinet 100.

[0035] Two protective mechanisms 300 are provided, which are fixedly connected to both ends of the cabinet 100, and the opposite ends of the two protective mechanisms 300 are connected to the air inlet 110 and the air outlet 120, respectively.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, the protective mechanism 300 near the fan 200 includes an air duct 310 fixedly connected to one end of the cabinet 100. One opening of the air duct 310 is connected to the air inlet 110, and the other opening of the air duct 310 faces the ground. A dustproof net 320 is embedded and installed inside the other opening of the air duct 310. A moisture-absorbing net can be installed on the top of the dustproof net 320 as needed. This can filter the moisture in the passing air to improve the dryness inside the cabinet 100. It should be noted that the moisture-absorbing net needs to be used in conjunction with a dehumidification system or a drying system. Drying should be achieved when the moisture-absorbing net reaches the preset humidity without interfering with the internal structure of the cabinet 100. A moisture-absorbing mesh is used to prevent the mesh from becoming saturated with water, which could lead to excessive humidity inside the cabinet 100. A threaded groove 311 is provided on the inner side of another opening of the air duct 310. An external threaded sleeve 330 is threadedly connected to the inner side of the threaded groove 311, and a dustproof mesh 320 is fixedly connected to the inner side of the external threaded sleeve 330. An adjusting bracket 340 is fixedly connected to the inner side of the external threaded sleeve 330, and is positioned below the dustproof mesh 320. The horizontal cross-sectional shape of the adjusting bracket 340 is cross-shaped, and its corners are rounded. A limiting ring 350 is fixedly connected to the outer side of the external threaded sleeve 330, and the inner diameter of the limiting ring 350 is larger than the inner diameter of the threaded groove 311.

[0037] like Figure 3 and Figure 4 As shown, the protective mechanism 300 also includes a sealing assembly 360, which includes a sealing plate 361 and a circular frame 362. The sealing plate 361 is hinged to the inside of the air guide duct 310. The vertical cross-sectional dimension of the sealing plate 361 is larger than the horizontal cross-sectional dimension of the threaded groove 311. The circular frame 362 is fixedly connected to the top of the external threaded sleeve 330. The top of the circular frame 362 passes through the threaded groove 311 and contacts the sealing plate 361. A spring piece 363 that contacts the air guide duct 310 is fixedly connected to one end of the sealing plate 361 facing away from the circular frame 362. The spring piece 363 is always in a compressed state. A reserved groove 312 is opened on the inner side of the air guide duct 310. One end of the spring piece 363 passes through the interior of the reserved groove 312.

[0038] In this embodiment, during the user's shutdown maintenance of the dustproof net 320, when the user moves the dustproof net 320 out of the air duct 310 by using the external threaded sleeve 330, the external threaded sleeve 330 moves the circular frame 362 out of the air duct 310 together. At this time, the sealing plate 361 loses its obstruction, and the spring piece 363 drives the sealing plate 361 to rotate rapidly until it reaches the sealing thread groove 311. This can prevent the outside air from carrying solid impurities into the cabinet 100, so as to achieve a good sealing and protection effect.

[0039] When the user screws the external threaded sleeve 330 back into the threaded groove 311, the external threaded sleeve 330 drives the circular frame 362 to gradually move upward. The circular frame 362 lifts the sealing plate 361, and the sealing plate 361 rotates upward along the hinge with the air guide tube 310. When the external threaded sleeve 330 is rotated into place, the sealing plate 361 is vertically attached to the air guide tube 310, so that the air guide tube 310 is connected to the outside world, so as to achieve the effect of normal air guidance.

[0040] Common remote control cabinet structures include, but are not limited to, the following:

[0041] I. Cabinet 100 Structure: It adopts cold-rolled steel plate cabinet (thickness ≥2mm), single-opening front door structure (opening angle ≥130°); the internal mounting plate is pre-punched with standard DIN rail holes and cable holes, and the inside of the cable holes is embedded with insulating sealing plugs to support the quick installation of modular components; the cable management is divided into zones (power cable trays, signal cable trays, and dedicated fiber optic channels).

[0042] II. Control Core Unit: Both the PLC main unit and the intelligent control terminal are mounted on a guide rail. The PLC main unit handles logic operations and instruction output, and supports local I / O expansion and bus communication interfaces. The intelligent control terminal integrates a 4G / 5G communication module and has a built-in industrial-grade processor for remote instruction parsing.

[0043] III. Communication Architecture: Equipped with industrial Ethernet switches, wireless transmission modules (such as 4G DTUs) and protocol converters, all of which are installed on the corresponding guide rails. They support industrial protocols such as Modbus TCP and PROFINET, are compatible with TCP / IP communication standards, and use metal shielded cable trays to isolate signal lines and power lines, reducing electromagnetic interference.

[0044] III. Energy Management System: The dual power input configuration is installed on the inner bottom wall of the cabinet (mains power + UPS), equipped with an intelligent switching device, an independent circuit design for the 24VDC switching power supply, isolation between digital and analog power supply, and the battery pack supports offline operation with a capacity configured according to the standard of 72 hours of battery life.

[0045] IV. Safety Protection System: Three-level lightning protection devices are installed on the outside of the cabinet 100 (power supply end, communication end, signal end), with a dual safety mechanism of emergency stop button and hardware watchdog. The overall protection level of the cabinet 100 needs to reach IP54, and it is equipped with temperature and humidity sensors and an automatic fire extinguishing system.

[0046] It should be noted that the fan 200, air inlet 110, and air outlet 120 must all be flush with the high heat generation locations in the cabinet 100, and it is necessary to ensure that the electrical components and wiring inside the cabinet 100 can operate normally. When the fan 200 is far from the heat generation location, the heat dissipation airflow can be directionally guided through heat dissipation auxiliary structures such as air guide pipes or air guide blades. The specific location and heat dissipation auxiliary structures need to be selected according to the actual situation. When multiple sets of fans 200 need to be set, the ratio of the number of fans 200, air inlets 110, air outlets 120, and protective mechanisms 300 is 1:1:1:2.

[0047] Working principle: During the process of the fan 200 drawing in outside air, the outside air enters the inside of the air guide duct 310 through the lower opening. When the air passes through the adjacent dustproof net 320, the dustproof net 320 filters out solid impurities mixed in the air. Then, the clean air is blown by the fan 200 to the heating position through the air inlet 110. The air carries away the heat from the heating position and is discharged to the outside through the air outlet 120 and another air guide duct 310, so as to effectively dissipate heat from the heating element inside the cabinet 100. In this process, the heat dissipation airflow enters the cabinet 100 from bottom to top through the air guide duct 310 and exits the cabinet 100 from top to bottom through the air guide duct 310. This can effectively prevent rainwater from entering the interior of the cabinet 100, thereby reducing the probability of short circuit when the internal structure of the cabinet 100 is exposed to water. Moreover, it can also improve the protective strength of the protective mechanism 300 without moving any structure.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
