Description

Technical Field

[0001] This utility model relates to the field of control cabinet technology, and in particular to an explosion-proof control cabinet. Background Technology

[0002] In the field of explosion-proof control cabinets used in flammable and explosive hazardous environments, the effectiveness and reliability of the heat dissipation system directly affect the operational stability and safety of the equipment. Existing explosion-proof control cabinets mostly employ a design with fixed-position air inlet and outlet pipes, a structure with significant technical drawbacks. In practical applications of explosion-proof control cabinets, the fixed positions of the air inlet and outlet pipes result in a severe lack of installation flexibility.

[0003] Due to the fixed layout of pipelines, when complex obstacles (such as industrial pipelines, other equipment, or building structures) exist on site, control cabinets cannot effectively avoid them by adjusting the positions of the inlet and outlet air pipes. This often forces a change in installation location or large-scale modifications to the site environment, increasing construction and time costs. Furthermore, in confined working areas, such as underground pipe corridors or dense equipment compartments, fixed pipelines cannot be adapted to the limited space. Spatial interference can easily reduce the cross-sectional area of ​​the pipeline ventilation, even creating dead zones, resulting in poor airflow and a significant decrease in equipment heat dissipation efficiency. This rigid pipeline layout not only limits the installation location of explosion-proof control cabinets but also makes it difficult for the equipment to fully utilize its heat dissipation function in complex environments, failing to meet the stringent requirements for stable operation in hazardous environments. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an explosion-proof control cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof control cabinet includes a housing and a multi-component integrated assembly. Multiple support legs are fixedly mounted on the bottom of the housing. The housing has an opening / closing port, a lower rotating port, and an upper rotating port. Each of the opening / closing port, lower rotating port, and upper rotating port has an opening / closing door, a rotating ring, and a turntable, respectively. An air inlet pipe is mounted on the rotating ring, and an exhaust fan and an air outlet pipe are mounted on the turntable. A drive shaft is rotatably mounted on the housing via two support plates. The drive shaft is connected to the rotating ring and the turntable via a transmission mechanism. A drive motor is mounted on the upper support plate and is connected to the drive shaft via a rotation mechanism.

[0007] Preferably, the transmission mechanism includes a transmission gear fixedly mounted on the transmission shaft, and both the rotating ring and the turntable are provided with gear rings that mesh with the transmission gear.

[0008] Preferably, the rotating mechanism includes a drive gear mounted on the output shaft of the drive motor, the drive gear meshing with the transmission gear above.

[0009] Preferably, two connecting frames are fixedly provided on the inner wall of the housing, and both connecting frames are U-shaped.

[0010] Preferably, the vertical cross-sectional views of the lower rotating opening, the rotating ring, and the upper rotating opening are all T-shaped, and the vertical cross-sectional view of the turntable is T-shaped.

[0011] Preferably, the inlets and outlets of the air inlet and outlet are both vertically downward, and protective nets are threaded onto both the air inlet and outlet.

[0012] The beneficial effects of this utility model are:

[0013] 1. With its rotatable and adjustable inlet and outlet pipes, the explosion-proof control cabinet can effectively avoid various obstacles at the installation site, such as industrial pipelines, other equipment, or building structures. Whether in narrow underground pipe corridors or densely packed equipment compartments, the pipe layout can be flexibly adjusted to ensure that the inlet and outlet are in the optimal ventilation position, significantly improving the installation flexibility and applicability of the equipment in complex environments.

[0014] 2. Through the ingenious design of the transmission and rotation mechanisms, the intake and exhaust pipes can be adjusted synchronously without separate control, simplifying the operation process, reducing airflow turbulence problems that may be caused by individual adjustment, and ensuring that the airflow inside the cabinet forms a stable and efficient heat dissipation path.

[0015] 3. The housing adopts a connecting frame to fix the upper and lower sections. Combined with the limiting design formed by the T-shaped and T-shaped cross sections, the relative position of the rotating ring, turntable and housing is always stable during the rotation adjustment of the air inlet and outlet pipes. This avoids the impact of component displacement on sealing and heat dissipation, and ensures the safe and reliable operation of the explosion-proof control cabinet under complex working conditions.

[0016] 4. The air inlet and outlet pipes are set downwards, and together with the protective net, they can effectively block dust and debris from entering the cabinet, reducing the risk of failure caused by dust accumulation in the multi-component integrated components. At the same time, the protective net is easy to disassemble and clean, making maintenance convenient and extending the service life of the equipment. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 An explosion-proof control cabinet includes a housing 1 and a multi-component integrated assembly. The multi-component integrated assembly includes: an electrical control assembly (including controllers, relays, etc., for logic control and circuit switching of the equipment), a power supply assembly (responsible for converting AC power to stable DC power and providing backup power), a signal transmission and conversion assembly (for connecting lines, isolating interference, and converting non-electrical signals), a protection and monitoring assembly (including surge protectors, temperature sensors, etc., to prevent the equipment from being affected by voltage surges, abnormal temperature and humidity), and auxiliary components (such as indicator lights, push-button switches, etc., for facilitating equipment status display and manual operation). These components work together to ensure the safe and stable operation of the explosion-proof control cabinet in hazardous environments, achieving effective control and protection of electrical equipment.

[0026] Multiple support legs 4 are fixedly provided at the bottom of the housing 1. The housing 1 is provided with an opening and closing port, a lower rotating port 2 and an upper rotating port 17. The opening and closing port, the lower rotating port 2 and the upper rotating port 17 are respectively provided with an opening and closing door, a rotating ring 3 and a turntable 6. The rotating ring 3 is provided with an air inlet pipe 5, and the turntable 6 is provided with an exhaust fan 15 and an air outlet pipe 7. The housing 1 is rotatably provided with a drive shaft 10 through two support plates 9. The drive shaft 10 is connected to the rotating ring 3 and the turntable 6 through a transmission mechanism. The upper support plate 9 is provided with a drive motor 11. The drive motor 11 is connected to the drive shaft 10 through a rotation mechanism.

[0027] The transmission mechanism includes a transmission gear 13 fixedly mounted on the transmission shaft 10, and gear rings 14 meshing with the transmission gear 13 on both the rotating ring 3 and the turntable 6. The rotation mechanism includes a drive gear 12 mounted on the output shaft of the drive motor 11, which meshes with the transmission gear 13 above it. Using these components, the rotation adjustment of the rotating ring 3 and the turntable 6 relative to the housing 1 can be achieved after the drive motor 11 is started.

[0028] Two connecting brackets 16 are fixedly provided on the inner wall of the housing 1, and both connecting brackets 16 are U-shaped. Due to the setting of the lower rotation port 2, the housing 1 is divided into upper and lower sections, and the connecting brackets 16 are used to achieve a fixed connection between the upper and lower sections.

[0029] The vertical cross-sectional views of the lower rotating opening 2, the rotating ring 3, and the upper rotating opening 17 are all T-shaped, while the vertical cross-sectional view of the turntable 6 is T-shaped. These shapes serve a limiting function, preventing the rotating ring 3 from moving horizontally relative to the housing 1 and preventing the turntable 6 from moving vertically relative to the housing 1.

[0030] Both the inlet pipe 5 and the outlet pipe 7 have their openings pointing vertically downwards, and both are threaded with protective mesh 8. This downward orientation prevents dust from falling vertically into them, while the protective mesh 8 serves as a filter.

[0031] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods for each component all employ mature methods from the prior art, and will not be detailed here. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0032] In use, after the drive motor 11 starts, the drive gear 12 on the output shaft drives the transmission gear 13 on the transmission shaft 10 to rotate. Based on the transmission of the rotation mechanism, the transmission shaft 10 rotates. Through the meshing of the transmission gear 13 with the gear ring 3 and the gear ring 14 on the turntable 6, the rotating ring 3 and the turntable 6 rotate simultaneously relative to the housing 1. The air inlet pipe 5 on the rotating ring 3 and the air outlet pipe 7 on the turntable 6 rotate accordingly, realizing position adjustment. The air inlet pipe 5 introduces outside air into the housing 1, removes heat, and then the exhaust fan 15 accelerates the airflow, which is then discharged through the air outlet pipe 7, completing the heat dissipation cycle.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
