Description

Technical Field

[0001] This application relates to the field of outdoor control cabinet technology, and more specifically, to an outdoor environmental monitoring terminal control cabinet. Background Technology

[0002] The outdoor environmental monitoring terminal control cabinet is a specialized enclosure designed for outdoor environments, used to integrate, protect, and manage environmental monitoring equipment. Based on a robust enclosure structure, it houses core components such as temperature and humidity sensors, PM2.5 detectors, anemometers, data loggers, communication modules (e.g., 4G / 5G, LoRa modules), and backup power supplies (e.g., lithium batteries, solar charging modules). It provides a stable working environment for internal equipment in complex outdoor conditions, while simultaneously enabling real-time acquisition, temporary storage, and remote transmission of surrounding environmental data.

[0003] When this control cabinet is used in colder northern cities, the lowest temperature can drop to -40°C. However, the shell design of most outdoor environmental monitoring terminal control cabinets is not designed to enhance thermal insulation performance for extreme low temperature scenarios. The shell is mostly made of ordinary cold-rolled steel plate or basic stainless steel, without adding a thermal insulation layer or only equipped with a simple thermal insulation structure. Heat is easily lost through the shell wall, making it impossible to form a stable temperature environment inside, which affects the performance of the outdoor environmental monitoring terminal control cabinet. Utility Model Content

[0004] To address the aforementioned issues, this application provides an outdoor environmental monitoring terminal control cabinet.

[0005] The outdoor environmental monitoring terminal control cabinet provided in this application adopts the following technical solution: An outdoor environmental monitoring terminal control cabinet includes a housing, on which a heat dissipation structure is provided. The heat dissipation structure includes at least one heat dissipation vent and at least one heat dissipation grille. Sealing components are installed at both the heat dissipation vents and the auxiliary heat dissipation grilles; The sealing assembly includes a sealing cover and a rubber ring disposed between the sealing cover and the housing. The sealing cover is detachably connected to the housing by bolts and is used to seal the corresponding heat dissipation vents and heat dissipation grilles in a non-heat dissipation state.

[0006] With the above technical solution, after installation by the staff, the heat dissipation vents and heat dissipation grilles can be tightly sealed, completely blocking the entry of extremely cold air from the outside into the cabinet through these gaps, and preventing the cold air from forming convection with the heated air inside the cabinet, which would cause rapid heat loss.

[0007] Furthermore, the housing contains a heater and a temperature sensor, and the heater contains a controller.

[0008] Through the above technical solution, the heater evenly releases heat into the internal space of the casing. The heat slowly diffuses inside the cabinet, gradually increasing the ambient temperature around the electrical components, ensuring that the electrical components are always in a stable temperature environment, and avoiding damage to the electrical components due to low temperature.

[0009] Furthermore, the controller is electrically connected to the heater and temperature sensor.

[0010] Furthermore, the shell has an internal interlayer, and the interlayer is lined with insulating cotton.

[0011] Through the above technical solutions, the insulation cotton can reduce heat loss inside the cabinet in low-temperature environments and provide basic insulation for electrical components.

[0012] Furthermore, electrical components are located inside the housing, and a connecting shell is located on the top of the housing.

[0013] Furthermore, the connecting shell has multiple cooling fans inside and multiple ventilation holes on the outside.

[0014] Furthermore, each heat dissipation hole is equipped with a flexible silicone one-way valve.

[0015] Furthermore, the front of the housing is provided with two sealed doors, each with a lock at one end.

[0016] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting the sealing components, the heat dissipation vents and heat dissipation grilles can be tightly sealed after installation by the staff, completely blocking the external extremely cold airflow from entering the cabinet through these gaps, and avoiding the formation of convection between the cold air and the heated air in the cabinet, which would cause the heat to be lost quickly. (2) This utility model can reduce heat loss in the cabinet in low-temperature environments by using the insulation cotton set in the interlayer inside the shell, and provide basic insulation for electrical components; (3) The heater of this utility model releases heat evenly into the internal space of the shell. The heat slowly diffuses in the cabinet, gradually increasing the ambient temperature around the electrical components, ensuring that the electrical components are always in a stable temperature environment, and avoiding damage to the electrical components due to low temperature.

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0020] Reference Figures 1-5 An outdoor environmental monitoring terminal control cabinet includes a housing 1, on which a heat dissipation structure is provided. The heat dissipation structure includes at least one heat dissipation port 12 and at least one heat dissipation grille 13 on the housing 1. Sealing components are provided at both the heat dissipation vent 12 and the auxiliary heat dissipation grille 13; The sealing assembly includes a sealing cover 6 and a rubber ring 11 disposed between the sealing cover 6 and the housing 1. The sealing cover 6 is detachably connected to the housing 1 by bolts and is used to seal the corresponding heat dissipation port 12 and heat dissipation grille 13 in a non-heat dissipation state.

[0021] When the temperature sensor detects that the temperature inside the housing 1 is lower than the set threshold, it will transmit the signal to the controller 4 inside the heater 3. The controller 4 will then start the heater 3. After the heater 3 is started, it will release heat evenly into the interior space of the housing 1 through resistance heating or PTC ceramic heating. The heat will slowly diffuse inside the cabinet and gradually increase the ambient temperature around the electrical components 2.

[0022] During this process, the temperature sensor will continuously collect the temperature data inside the cabinet and feed it back to the controller 4. When the controller 4 detects that the feedback temperature has risen back to the preset suitable working range (such as 10℃~25℃), it will automatically output a shutdown signal to cut off the power supply to the heater 3, so as to avoid overheating and excessive temperature inside the cabinet, while reducing energy consumption and ensuring that the electrical components 2 are always in a stable temperature environment, so as to avoid damage to the electrical components 2 due to low temperature.

[0023] Before heating, the controller 4 synchronously uploads the data to the monitoring platform of the remote control center. After receiving the signal in real time through the platform, the staff of the control center can clearly see that the control cabinet is currently in low temperature protection mode and needs to cooperate to enhance the insulation effect inside the cabinet. The staff will bring the appropriate sealing cover 6 and rubber ring 11 to the site. Before installation, they will clean the dust, snow and other debris on the outside of the heat dissipation vent 12 and heat dissipation grille 13 to ensure that the mating surface is clean. Then, the rubber ring 11 is tightly fitted into the edge groove of the sealing cover 6, and the sealing cover 6 is aligned with the mounting holes of the heat dissipation vent 12 and heat dissipation grille 13. The bolts are then tightened evenly point by point.

[0024] Reference Figures 1-2 The housing 1 contains a heater 3 and a temperature sensor. The heater 3 contains a controller 4, which is electrically connected to the heater 3 and the temperature sensor.

[0025] Reference Figure 5 The shell 1 has an inner layer, and the inner layer is filled with thermal insulation cotton 14.

[0026] The inner cavity of the casing 1 contains insulation cotton 14, which reduces heat loss from the cabinet in low-temperature environments and provides basic insulation for the electrical components 2. In hot weather, the insulation cotton 14 can significantly slow down or even block the rate and amount of external heat penetration into the cabinet, preventing the ambient temperature inside the cabinet from rising rapidly due to high external temperatures. In cold weather, it reduces the heat generated by the heater 3 from being lost outward through the walls of the casing 1, prolonging the time heat remains inside the cabinet and keeping the internal temperature stable.

[0027] Reference Figures 1-3 The housing 1 has an electrical component 2 inside, a connecting shell 7 on the top of the housing 1, multiple cooling fans 8 inside the connecting shell 7, and multiple heat dissipation holes 9 on the outside of the connecting shell 7. Each heat dissipation hole 9 has a flexible silicone one-way valve inside.

[0028] In hot weather, the high outdoor temperature not only causes the housing 1 to absorb a large amount of external heat, but the heat generated by the electrical components 2 inside the housing during operation also tends to accumulate more easily due to the poor external heat dissipation conditions, leading to a rapid increase in the internal temperature. When the temperature sensor inside the housing 1 detects that the temperature exceeds the threshold for the electrical components 2 to operate appropriately (such as 35°C), multiple cooling fans 8 connected to the inside of the housing 7 at the top of the housing 1 will immediately start, enhancing heat dissipation efficiency through active ventilation. When the cooling fan 8 operates at high speed, it creates a stable negative pressure inside the connecting shell 7. This accelerates the upward flow of hot air, which becomes less dense after being heated, within the shell 1, allowing it to quickly enter the connecting shell 7. It also prevents hot air from seeping back into the cabinet through gaps. Under the continuous thrust of the cooling fan 8, the hot air entering the connecting shell 7 rapidly moves towards the multiple ventilation holes 9 on the outside of the connecting shell 7. At this time, the flexible silicone one-way valves inside each ventilation hole 9 are smoothly pushed open by the positive pressure of the hot air, forming an unobstructed airflow channel. This allows the air carrying a large amount of heat to be quickly expelled from the cabinet, effectively reducing the internal temperature of the shell 1 and creating a suitable working environment for the electrical components 2 at no more than 30°C, preventing performance degradation due to high temperatures.

[0029] In cold weather, the cooling fan 8 is not turned on, and the flexible silicone one-way valve is in a closed state to prevent external cold air from entering the housing 1.

[0030] Reference Figures 1-5 The front side of the housing 1 is provided with two sealing doors 10, and each of the two sealing doors 10 is provided with a door lock 5 at one end.

[0031] During daily outdoor use, the sealed door 10 fits tightly against the housing 1 via an edge sealing strip (existing technology, not shown in the diagram), effectively preventing external dust, rainwater, sand, and other impurities from entering the cabinet. The door lock 5 prevents the sealed door 10 from opening automatically due to outdoor gusts of wind, accidental impacts, or human error, ensuring the sealing effect remains intact. Working Principle: When the temperature sensor detects that the temperature inside the housing 1 is lower than the set threshold, it immediately transmits a signal to the controller 4 inside the heater 3. The controller 4 simultaneously uploads the low-temperature signal to the remote control center, and then starts the heater 3. After receiving the signal, the control center personnel bring the sealing cover 6 and rubber ring 11 to the site, clean the debris outside the heat dissipation vent 12 and heat dissipation grille 13, align the sealing cover 6 with the holes and tighten it with bolts to seal the heat dissipation vent 12 and heat dissipation grille 13 to enhance heat preservation. The heater 3 releases heat into the housing 1 through resistance or PTC ceramic heating. The insulation cotton 14 reduces heat loss through the walls of the housing 1. The temperature sensor continuously feeds back data to the controller 4. When the temperature rises back to the range of 10℃~25℃, the controller 4 cuts off the power to the heater 3 to prevent overheating. During this process, the cooling fan 8 is not turned on, and the flexible silicone one-way valve in the heat dissipation hole 9 remains closed to prevent external cold air from entering.

[0032] When the temperature sensor detects that the temperature inside the housing 1 exceeds 35°C, the controller 4 triggers the cooling fan 8 inside the connecting housing 7 to start. The high-speed operation of the cooling fan 8 creates a negative pressure inside the connecting housing 7, accelerating the upward flow of hot air from inside the housing into the connecting housing 7, while preventing the infiltration of high-temperature air from the outside. Under the thrust of the cooling fan 8, the hot air moves towards the heat dissipation hole 9, pushing the flexible silicone one-way valve to open and being discharged from the outside through the heat dissipation hole 9. At this time, the insulation cotton 14 blocks the penetration of external heat into the cabinet, assisting the cooling fan 8 in reducing the temperature inside the housing 1 until the temperature drops below 30°C. The cooling fan 8 then stops operating, and the flexible silicone one-way valve automatically closes. At this time, the multiple sealing covers 6 are not installed, and the heat dissipation vents 12 and heat dissipation grilles 13 participate in heat dissipation.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
