Description

Technical Field

[0001] This application relates to the field of electrical control cabinets, and more particularly to a grain warehouse control cabinet. Background Technology

[0002] The higher the level of automation in existing grain silos, the less personnel generally enter the silo except for equipment inspection and maintenance. Therefore, the control cabinets of the grain silos need to be located outside the silo in harsh conditions. They not only need to be protected from sun, wind, and rain, but also from insects and ensure proper heat dissipation. Heat dissipation is particularly important, as it requires many openings, which can easily introduce insects into the cabinet. Insects entering the cabinet may cause local short circuits or other malfunctions. If the control cabinet is set up in a sealed shape, the heat dissipation problem is more difficult to solve, especially in extreme environments such as direct sunlight or the operation of high-power equipment. In addition, relying on fans for cooling will consume energy, and cooling will not be possible if the fans fail.

[0003] Chinese patent application CN218124018U, entitled "An Insect-Proof Grain Warehouse Control Cabinet," discloses an insect-proof grain warehouse control cabinet, belonging to the field of control cabinet technology. This insect-proof grain warehouse control cabinet includes a base and a cabinet body fixedly connected to the upper surface of the base. First insect-proof boxes are detachably connected to the front and rear sides of the base, and second insect-proof boxes are detachably connected to the left and right sides of the base. Two ventilation openings and an insect-attracting opening are provided on the left and right sides of the cabinet body. An exhaust device is provided on the inner wall of each ventilation opening. This insect-proof grain warehouse control cabinet, by mounting the cabinet body on the base, increases the height of the cabinet body from the ground. Combined with the first and second insect-proof boxes, it ensures insect repellency around the cabinet body, thereby preventing insects from entering the control cabinet from the ground. Through the cooperation of the ventilation openings, ventilation ducts, and insect-proof covers, and with the action of the exhaust device, it ensures air circulation and heat dissipation within the cabinet while preventing insects from entering the cabinet. Insect repellents need to be replaced frequently and are difficult to maintain. Once the repellent becomes ineffective, insects may still enter the cabinet, causing local short circuits or other malfunctions. Utility Model Content

[0004] This application provides a grain storage control cabinet to at least solve the problems of balanced insect prevention and heat dissipation in the prior art.

[0005] According to a first aspect of this application, a control cabinet is provided, including a cabinet body and a ventilation duct. The ventilation duct has at least one outlet and an air inlet and an air outlet. The air outlet is located inside the cabinet body, which enables the ventilation duct to communicate with the interior of the cabinet body. At least a portion of the ventilation duct body between the air inlet and the air outlet is buried underground.

[0006] Compared with the prior art, the control cabinet of this application has the following advantages: Without any driving device, this system utilizes temperature difference to achieve automatic air circulation, reducing the temperature inside the cabinet. By installing ventilation ducts, the area of ​​the cabinet's air intake channel can be reduced, or other air intake channels can be eliminated, reducing the risk of insects entering the cabinet. The ventilation ducts in this application are buried underground. The control cabinet primarily requires significant heat dissipation during hot weather. During cooler times, the cabinet itself can directly dissipate heat. However, on hot, sunny days, direct sunlight on the control cabinet causes its overall temperature to rise. At this time, the outside air temperature is high, resulting in slow heat dissipation. This application buries the ventilation ducts one meter below the ground. The underground temperature is higher than the ground temperature; the deeper the duct, the lower the temperature and the better the effect. This also increases construction costs. A conventional depth of about one meter is sufficient, and a certain length is needed for better results, typically exceeding 10 meters. Thus, the air temperature inside the ventilation duct is lower than the cabinet temperature, but the cabinet's temperature rises, density decreases, and pressure decreases, allowing the air to flow automatically. That is, without external power, air can slowly flow into the cabinet, achieving the desired heat dissipation.

[0007] In one embodiment, the cabinet is installed on the ground or countertop, and the cabinet is connected to at least one cable conduit, with at least a portion of the cable conduit buried underground. The ventilation duct extends along with the cable conduit, so that at least a portion of the ventilation duct is buried underground. Thus, there is no need to install the ventilation duct separately; it can be directly inserted into the cable conduit.

[0008] In one embodiment, the air inlet is equipped with an air filter to prevent foreign objects and insects from entering the cabinet.

[0009] In one embodiment, the ventilation duct has a vertical section and a horizontal section inside the cabinet. The horizontal section is located above the vertical section and is positioned near the top of the cabinet. The top temperature is relatively higher, resulting in better heat exchange and rapid heating of the air inside the ventilation duct. This increases the temperature difference and the pressure difference caused by density, leading to faster airflow.

[0010] In one embodiment, the cabinet is divided into multiple functional areas, and a horizontal section passes through the multiple functional areas.

[0011] According to a second aspect of this application, a grain storage control cabinet is provided, including the aforementioned control cabinet. The side wall of the control cabinet is equipped with a touch-sensitive display screen, so that the grain storage status can be observed in real time through the display screen. Currently, grain storage facilities are basically equipped with automated control and automated monitoring, such as temperature and humidity. In addition, grain feeding and discharging are also fully automated, that is, they can be operated directly on the control cabinet. Using a touch-sensitive display screen, the grain storage facility can be controlled without opening the control cabinet, thus preventing insects or foreign objects from entering the control cabinet when it is opened.

[0012] In one embodiment, the cabinet is equipped with an exhaust fan, which has a mesh grille to prevent insects or other foreign objects from entering the cabinet.

[0013] In one embodiment, the exhaust section is provided with a third partition, the third partition is provided with an exhaust port, and the exhaust port is provided with a fan. The fan can quickly exhaust the internal air to the outside of the cabinet, so as to achieve better heat dissipation in more extreme environments.

[0014] In one embodiment, the cabinet is provided with an air inlet, which includes a first partition and a second partition. The first partition has a first air vent, and the second partition has a second air vent. The first and second air vents are offset by a certain position, and a filter layer is provided between the first and second partitions. The filter layer can be made of sponge or porous gas foam material, which can block foreign objects and has good air permeability.

[0015] In one embodiment, the side wall of the cabinet is provided with a spare air inlet, which can prevent the heat dissipation effect from decreasing when the ventilation pipe is blocked. The ventilation pipe is designed to be long and is prone to accidents, so setting a spare air inlet can prevent accidents.

[0016] In one embodiment, an arc-shaped pipe is provided on the outside of the backup air inlet, and a one-way valve is provided on the inside of the backup air inlet. The one-way valve is installed in the backup air inlet in a manner that allows it to rotate relative to the backup air inlet, thus providing a better rainproof effect.

Other features of this application will become readily apparent from the following description. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, features, and advantages of this application more apparent and understandable, 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1: like Figure 1 and Figure 2 As shown, a control cabinet, particularly a grain silo control cabinet, includes a cabinet body 1 and a ventilation duct 2. The ventilation duct 2 has at least one section and includes an air inlet 21 and an air outlet 22. The air outlet 22 is located inside the cabinet body 1, allowing the ventilation duct 2 to communicate with the interior of the cabinet body 1. At least a portion of the ventilation duct 2 between the air inlet 21 and the air outlet 22 is buried underground. To ensure effective heat dissipation in the absence of power, the effective length of the ventilation duct 2 underground must exceed 10 meters, and the depth from the ground must exceed 1 meter. If the length cannot reach 10 meters, the surface area of ​​the ventilation duct can be increased, for example, by increasing the number of ventilation ducts, to meet the cooling requirements. If cost is not a concern, fins can be installed to increase the heat exchange effect. Cabinet doors 9 can be installed at both the front and back of the cabinet body 1 for convenient maintenance.

[0023] The specific number and size of ventilation ducts 2 are set according to the local highest temperature. If the highest temperature exceeds 40 degrees Celsius, for a grain warehouse control cabinet with a cabinet volume of about 1 cubic meter, the cross-sectional area of ​​one or more ventilation ducts 2 should exceed 1000 square millimeters.

[0024] like Figure 1 and Figure 2As shown, in one embodiment, the air inlet 21 is provided with an air filter 23. The air filter 23 can be a readily available air filter, which is low in cost. Since the filtration requirements of this application are low, a denser grille can also be installed at the air inlet 21 instead of a filter. The choice depends on the size of the cabinet 1. For larger cabinets with larger airflow, a grille with lower air resistance can be selected, which can also be considered a simple air filter 23. For smaller cabinets with a volume of less than 0.3 cubic meters, an air filter 23 can be used directly.

[0025] like Figure 2 As shown, in one embodiment, the ventilation duct 2 has a vertical section 24 and a horizontal section 25 inside the cabinet 1. The horizontal section 25 is located above the vertical section 24 and is positioned near the top of the cabinet 1. The ventilation duct 2 can be made of aluminum tubing, which has good heat conduction. For areas that require bending or turning, joints can be installed or connected via flexible hoses.

[0026] like Figure 2 and Figure 3 As shown, in one embodiment, the cabinet 1 is divided into multiple functional areas by an inner partition 10, and a horizontal section 25 passes through the multiple functional areas.

[0027] like Figure 5 As shown, in one possible embodiment, the cabinet 1 is installed on the ground or a platform 3. The platform 3 can be made of concrete or constructed of steel to prevent flooding during rainy weather. The side wall of the grain storage control cabinet is equipped with a touch-sensitive display screen 4. The display screen 4 is about 1.2 meters to 1.5 meters high for easy touch control and observation.

[0028] like Figure 1 and Figure 3 As shown, in one embodiment, the cabinet 1 is provided with an exhaust section 11, and the exhaust section 11 is provided with a grille 12. The mesh size of the grille 12 is less than 1mm, which can block most foreign objects.

[0029] like Figure 3 and Figure 4As shown, in one embodiment, the exhaust section 11 is provided with a third partition 13, which is located inside the cabinet 1. The third partition 13 is provided with an exhaust port 14, and the exhaust port 14 is provided with a fan 15. Multiple exhaust ports 14 can be provided and are arranged in a circle, with each exhaust port 14 corresponding to a fan 15. A temperature sensor can be installed inside the cabinet 1. When the temperature inside the cabinet 1 exceeds 55°C, the chip control circuit will automatically start the fan 15 to reduce the air pressure inside the cabinet 1, allowing the air in the ventilation duct 2 to quickly enter the cabinet 1 and lower the temperature inside the cabinet 1. The ventilation duct 2 is buried underground, and even in the south, the temperature is below 23°C year-round, thus providing good cooling effect without excessive energy consumption. To prevent insects from entering the cabinet 1 due to damage to the external grille 12, the external grille 12 is regularly inspected and replaced. A backup grille 12 is provided between the cabinet 1 and the third partition 13 to prevent insects from entering the control cabinet when the external grille 12 is replaced or damaged. A drainage groove 27 is installed on the cabinet 1 below the exhaust section 1 to facilitate drainage.

[0030] like Figure 3 and Figure 4 As shown, in one embodiment, the cabinet 1 is provided with an air inlet, which includes a first partition 16 and a second partition 17. The first partition 16 has a first air vent 18, and the second partition 17 has a second air vent 19. The first air vent 18 and the second air vent 19 are offset by a certain position. A filter layer is provided between the first partition 16 and the second partition 17. The filter layer is made of sponge or breathable foam material. The first partition 16 is an integral structure with the cabinet 1, and the second partition 17 is installed on the cabinet 1 by screws or other detachable means for easy replacement of the filter layer.

[0031] like Figure 3 and Figure 4 As shown, in one possible embodiment, the side wall of the cabinet 1 is provided with a spare air inlet 20.

[0032] like Figure 3 and Figure 4 As shown, in one possible embodiment, an arc-shaped pipe 5 is provided on the outer side of the backup air inlet 20, and a one-way valve 7 is provided on the inner side of the backup air inlet 20. The one-way valve 7 is installed in the backup air inlet 20 in a manner that allows it to rotate relative to the backup air inlet 20. Under the action of gravity, the one-way valve 7 is in a closed state, but it can be opened when the pressure difference exceeds a certain range. The arc-shaped pipe 5 has an opening facing downwards and can be equipped with a grid to block foreign objects.

[0033] like Figure 3 and Figure 5 As shown, the top of the cabinet 1 is equipped with an arc-shaped sunshade top 6. The arc structure reduces wind resistance and provides a certain cooling effect under direct sunlight compared to a single-layer cabinet 1. The bottom of the cabinet 1 is equipped with multiple power distribution ports 26, through which the wires of the cable conduit 8 can pass into the cabinet 1.

[0034] Example 2: like Figure 6 As shown, a control cabinet includes a cabinet body 1 and a ventilation duct 2. The ventilation duct 2 has at least one section and includes an air inlet 21 and an air outlet 22. The air outlet 22 is located inside the cabinet body 1, allowing the ventilation duct 2 to communicate with the interior of the cabinet body 1. At least a portion of the ventilation duct 2 between the air inlet 21 and the air outlet 22 is buried underground. The air inlet 21 can be located in a ventilated electrical distribution shaft or the ventilation duct 2 can extend to the ground, i.e., a separate air inlet 21 can be provided. The ventilation duct 2 has only a vertical section 24 inside the cabinet body 1, which is 70%-90% of the height of the cabinet body 1. This design results in a shorter ventilation duct 2 and lower flow resistance.

[0035] In one embodiment, the cabinet 1 is installed on the ground or a countertop 3. The cabinet 1 is connected to at least one cable conduit 8, and the cable conduit 8 is at least partially buried underground. The ventilation duct 2 extends along the cable conduit 8, so that the ventilation duct 2 is at least partially buried underground. This control cabinet can not only be used in grain silos, but can also be extended to all control cabinets and electrical cabinets installed on the ground. Even if it is not installed on the ground, as long as there is a possibility of installing the ventilation duct 2 underground, the technical solution of this application can be used to achieve a good cooling effect without increasing energy consumption.

[0036] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.
