Description

Technical Field

[0001] This application relates to the field of electrical automation control cabinet technology, and in particular to an electrical automation control cabinet that is easy to maintain. Background Technology

[0002] Electrical automation control cabinets are key equipment used in industrial production and power systems for the centralized installation, protection, and control of electrical components. The stable operation of the internal electrical equipment is directly related to the reliability of the entire system. Therefore, regular maintenance of the control cabinet is an essential maintenance procedure.

[0003] Traditional control cabinets typically have only one main door on the front for maintenance. Operators must open this door and enter the cabinet to inspect and maintain the electrical equipment installed on the sides and in the corners.

[0004] However, with maintenance only conducted through a single main cabinet door, operators are limited by the internal space of the control cabinet, making it difficult to reach the equipment located in the corners on both sides, and their line of sight is obstructed, making maintenance extremely inconvenient. This not only leads to low maintenance efficiency and prolonged equipment downtime, but also poses safety hazards because operators must remain in the confined space inside the cabinet for extended periods. It fails to meet the dual requirements of convenience and safety for maintenance in space-constrained environments. Utility Model Content

[0005] The purpose of this application is to provide an electrical automation control cabinet that is easy to maintain, in order to solve the problems of maintenance difficulties, low efficiency and safety hazards caused by operators having to reach into the cabinet to operate when traditional control cabinets are only maintained through a single cabinet door.

[0006] To achieve the above objectives, this application provides an electrical automation control cabinet that is easy to maintain, comprising:

[0007] The main body of the control cabinet has space to accommodate electrical equipment; a cabinet door is provided on one side of the main body of the control cabinet.

[0008] Inspection doors are provided on opposite sides of the main body of the control cabinet, and the inspection doors and cabinet doors are respectively located on different side walls of the main body of the control cabinet.

[0009] Ventilation mesh is installed on the inspection door; an exhaust system is installed on the top of the control cabinet.

[0010] Preferably, the cabinet door is rotatably mounted on the control cabinet body via a hinge, and the cabinet door is equipped with a lock.

[0011] Preferably, stepped grooves are formed on opposite sides of the control cabinet body; the inspection door is rotatably mounted in the stepped groove via a hinge.

[0012] Preferably, a sealing gasket is provided between the inspection door and the step groove.

[0013] Preferably, the exhaust assembly includes: a conical rainproof housing, which is disposed on the top of the control cabinet body;

[0014] A fan frame is installed in the internal cavity of the conical rainproof shell, and the interior of the fan frame is connected to the interior of the control cabinet body;

[0015] An exhaust fan is installed inside the fan frame;

[0016] The conical rainproof shell has an exhaust vent inside, which is symmetrically located on both sides of the fan frame;

[0017] A first dustproof screen is installed inside the exhaust vent.

[0018] Preferably, at least two exhaust fans are provided inside the fan frame, and the exhaust fans are arranged along the extension direction of the fan frame.

[0019] Preferably, the control cabinet further includes: limit components; the limit components are symmetrically arranged on the inner wall of the control cabinet body, and the limit components correspond to the positions of the two inspection doors respectively.

[0020] Preferably, the limiting component includes:

[0021] The mounting base is fixedly installed on the inner wall of the control cabinet body;

[0022] The pull rod is slidably inserted inside the mounting base;

[0023] A limit block is fixedly installed at the end of the pull rod facing the access door;

[0024] A spring is fitted onto the outside of the pull rod;

[0025] One end of the spring abuts against the inner wall of the mounting base, and the other end of the spring abuts against the limiting block.

[0026] Preferably, the mounting base has a plug-in groove on the side facing the access door; a plug-in block is fixedly installed on the side of the access door facing the mounting base;

[0027] The plug-in block has a positioning groove, and one end of the limiting block can be slidably inserted into the inside of the positioning groove;

[0028] The plug-in block is configured to plug into the plug slot when the access door is closed.

[0029] Preferably, the control cabinet further includes: a rain cover, which is disposed on the outside of the ventilation mesh;

[0030] The bottom of the rain cover has an air inlet, and the air inlet is equipped with a second dustproof net.

[0031] This application provides an electrical automation control cabinet that facilitates maintenance. By installing access doors on opposite sides of the main body of the cabinet, direct and partial maintenance of the internal areas on both sides is achieved. Operators can maintain specific equipment without having to enter the cabinet, significantly improving the convenience and safety of maintenance operations.

[0040] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0041] In traditional electrical automation control cabinets, operators must open a single cabinet door and reach inside to perform maintenance. Due to the limited internal space, it is difficult to reach electrical equipment installed on the sides and corners, and visibility is obstructed, making maintenance of specific areas inside the control cabinet extremely inconvenient. Therefore, traditional control cabinets, with only a single door, suffer from low maintenance efficiency, high operational difficulty, and potential safety hazards.

[0042] To address the aforementioned problems, this application provides an electrical automation control cabinet that is easy to maintain, referring to... Figure 1 and Figure 2 As shown, it includes:

[0043] The main body of the control cabinet 1 is the core support and protection structure of the entire device. It is used to house and protect various electrical equipment, such as circuit breakers, contactors, PLC controllers and wiring terminals.

[0044] Cabinet door 2, installed on one side of the control cabinet body 1, serves as the main maintenance access. Operators can perform overall inspection and maintenance of the internal equipment by opening cabinet door 2. Cabinet door 2 protects the internal equipment when closed.

[0045] Inspection doors 3 are located on both sides of the control cabinet body 1, and are not on the same side wall as cabinet door 2. Each inspection door 3 is an independent maintenance passage. Operators can directly maintain the equipment on both sides of the control cabinet through the inspection doors 3 without having to enter through cabinet door 2.

[0046] Ventilation mesh 4 is a through-hole formed in the access door 3. When the access door 3 is closed, outside air can enter the control cabinet through these mesh openings. Ventilation mesh 4 provides an airflow channel for the control cabinet.

[0047] The exhaust assembly 5 is installed on the top of the control cabinet body 1. This assembly contains a fan that extracts hot air from inside the control cabinet during operation. The exhaust assembly 5, together with the ventilation mesh 4 on the access door 3, forms a heat dissipation system.

[0048] It should be noted that the main body of the control cabinet 1 has three maintenance access points. The front door 2 is used for overall inspection and maintenance, while the side doors 3 are used for partial inspection. This design allows operators to choose different access points as needed. The cooling system uses a combination of natural air intake and forced exhaust. When the electrical equipment inside the control cabinet is operating, it generates heat, raising the air temperature. The hot air rises naturally and accumulates at the top of the control cabinet. After the exhaust assembly 5 is activated, it continuously draws the hot air from the top out of the cabinet. As the air inside the cabinet is drawn out, cooler outside air enters the control cabinet through the ventilation mesh 4 on the maintenance door 3. After entering from the bottom, the cool air absorbs the heat generated by the equipment, and its temperature rises, continuing to rise, forming an upward airflow. This establishes a continuous airflow circulation inside the control cabinet.

[0049] As can be seen from the above technical solution, the electrical automation control cabinet provided in this embodiment allows for easy maintenance. When maintenance is required on the equipment on the left side of the control cabinet, the operator only needs to open the left-side maintenance door 3. There is no need to open the front cabinet door 2 or lean into the cabinet. The operating space is ample, the visibility is good, and tools are easy to use. If the control cabinet needs to remain operational during maintenance, the cooling system can still function normally. Because the maintenance door 3 and ventilation mesh 4 on the other side remain unobstructed, the exhaust assembly 5 continues to operate, maintaining basic cooling requirements.

[0050] In some embodiments, see Figure 1 Cabinet door 2 is mounted on the control cabinet body 1 via hinges. One side of the hinge is fixed to the control cabinet body 1, and the other side is fixed to cabinet door 2, allowing cabinet door 2 to rotate around the hinge to open or close. This connection method ensures that cabinet door 2 provides sufficient operating space when open and fits tightly against the cabinet body when closed. A lock is installed on cabinet door 2. The lock is a device used to secure cabinet door 2; when cabinet door 2 is closed, the lock can lock it in the closed position. The function of the lock is to prevent cabinet door 2 from being accidentally opened, ensuring the safety of the equipment inside the control cabinet.

[0051] In some embodiments, see Figure 3 The control cabinet body 1 has stepped grooves 8 on opposite sides. The stepped grooves 8 are groove structures machined into the side walls of the control cabinet body 1. The stepped grooves 8 provide installation positions for the access door 3. The access door 3 is installed inside the stepped grooves 8 via hinges. One side of the hinge is fixed inside the stepped groove 8, and the other side is fixed to the access door 3, allowing the access door 3 to rotate and open around the hinge axis.

[0052] In some embodiments, a sealing gasket is provided between the access door 3 and the stepped groove 8. The sealing gasket is an elastic material installed on the contact surface between the access door 3 and the stepped groove 8. This material can fill the gap between the access door 3 and the stepped groove 8, ensuring the stability of the sealing effect.

[0053] In some embodiments, see Figure 4 The exhaust assembly 5 includes: a conical rainproof shell 51, a fan frame 52, an exhaust fan 53, an exhaust vent 54, and a first dustproof net 55.

[0054] A conical rainproof housing 51 is installed on the top of the control cabinet body 1. Its conical structure facilitates rainwater sliding off and prevents water accumulation, while the internal cavity provides installation space for other components.

[0055] The fan frame 52 is installed inside the cavity of the conical rainproof housing 51. The interior of the fan frame 52 is connected to the interior of the control cabinet body 1, forming an airflow path. This frame provides fixed support for the exhaust fan 53.

[0056] Exhaust fans 53 are disposed inside fan frames 52. At least two exhaust fans 53 are disposed inside fan frames 52, and these exhaust fans 53 are arranged along the extension direction of fan frames 52. Multiple exhaust fans 53 work together to improve heat dissipation efficiency.

[0057] The exhaust vents 54 are located inside the conical rainproof housing 51 and are symmetrically arranged on both sides of the fan frame 52. The exhaust vents 54 are channels for hot air to be discharged, and the symmetrical arrangement ensures uniform airflow.

[0058] The first dust filter 55 is installed inside the exhaust vent 54. The dust filter is made of mesh material, which can block dust and debris from entering while allowing air to pass through.

[0059] This embodiment effectively prevents rainwater from entering the control cabinet through the conical rainproof shell 51. Its conical structure allows rainwater to slide off quickly, preventing accumulation at the top. Multiple exhaust fans 53 operate in parallel, significantly enhancing ventilation capacity and improving overall heat dissipation efficiency. Exhaust vents 54 are symmetrically positioned on both sides of the fan frame 52, ensuring even airflow and preventing localized overheating areas inside the control cabinet. The first dust filter 55 reliably filters dust and impurities from the air, keeping the control cabinet clean. The entire ventilation system has a compact design, with tightly integrated components, convenient maintenance, and adaptability to various environmental conditions. The parallel arrangement of multiple exhaust fans 53 also improves system reliability. When a single exhaust fan 53 fails, the remaining fans 53 continue to operate normally, ensuring continuous heat dissipation.

[0060] In some embodiments, see Figure 3 and Figure 5 The control cabinet also includes limit components 6. The limit components 6 are symmetrically arranged on the inner wall of the control cabinet body 1, corresponding to the positions of the two access doors 3. Each limit component 6 includes a mounting base 61, a pull rod 62, a limit block 63, and a spring 64.

[0061] Mounting base 61 is fixedly installed on the inner wall of the control cabinet body 1, providing a mounting base for other components. Mounting base 61 has a plug-in slot 65 on the side facing the access door 3.

[0062] The pull rod 62 is slidably inserted inside the mounting base 61. The pull rod 62 can move back and forth within the mounting base 61 to achieve telescopic movement.

[0063] The limiting block 63 is fixedly installed at the end of the pull rod 62 facing the access door 3. The limiting block 63 moves with the pull rod 62 to achieve the locking function.

[0064] Spring 64 is sleeved on the outside of pull rod 62. One end of spring 64 abuts against the inner wall of mounting base 61, and the other end abuts against limit block 63. Spring 64 provides restoring force to pull rod 62.

[0065] A plug-in block 66 is fixedly installed on the side of the inspection door 3 facing the mounting base 61. A positioning groove 67 is provided on the plug-in block 66. When the inspection door 3 is closed, the plug-in block 66 is plugged into the plug-in groove 65 on the mounting base 61, and at the same time, one end of the limiting block 63 is slidably inserted into the interior of the positioning groove 67.

[0066] It should be noted that when the access door 3 is closed, the plug-in block 66 gradually approaches the mounting base 61 as the door moves. During the contact process, the inclined surface of the plug-in block 66 contacts the limiting block 63, pushing the limiting block 63 backward and compressing the spring 64 simultaneously. As the access door 3 continues to close, the plug-in block 66 is fully inserted into the plug-in slot 65. When the access door 3 is fully closed, the positioning slot 67 aligns with the limiting block 63. At this time, the spring 64 pushes the limiting block 63 forward, causing its end to slide into the positioning slot 67, completing the locking. When the access door 3 needs to be opened, the operator pulls the lever 62 outward. The lever 62 drives the limiting block 63 backward, causing its end to exit from the positioning slot 67. During this process, the spring 64 is further compressed. After the limiting block 63 completely exits the positioning slot 67, the access door 3 can be opened freely. After releasing the lever 62, the elastic force of the spring 64 pushes the limiting block 63 back to its initial position, preparing for the next locking operation.

[0067] This embodiment achieves positioning through the cooperation of the plug-in block 66 and the plug-in slot 65, ensuring the accuracy of the position of the access door 3 when closed. The plugging of the limit block 63 and the positioning slot 67 provides a reliable locking force, preventing the access door 3 from being opened accidentally. The design of the spring 64 makes the locking process automatic and easy to operate. The manual operation of the pull rod 62 provides a flexible unlocking method, ensuring that the access door 3 can be opened quickly. The entire limiting structure is reliable and has a long service life. The precise cooperation of each component can withstand vibration and impact, ensuring long-term stability. This design ensures both safety and ease of operation.

[0068] In some embodiments, see Figures 1-3 The control cabinet also includes a rain cover 7. The rain cover 7 is located on the outside of the ventilation mesh 4. The rain cover 7 is a protective structure that covers the outside of the ventilation mesh 4, and its main function is to prevent rainwater from directly entering the ventilation mesh 4.

[0069] The bottom of the rain cover 7 has an air inlet. The air inlet is the channel for air to enter, and its location at the bottom of the rain cover 7 can prevent rainwater from falling in directly.

[0070] The second dust filter 71 is installed at the air inlet. The second dust filter 71 is a filter device used to prevent dust and debris from entering the control cabinet through the air inlet.

[0071] As can be seen from the above technical solutions, this application provides an electrical automation control cabinet that is easy to maintain. The control cabinet includes: a main body with a cabinet door on one side and maintenance doors on opposite sides, with the maintenance doors and the cabinet door located on different side walls; ventilation mesh is provided on the maintenance doors, and an exhaust assembly is provided on the top of the main body. By providing maintenance doors on both sides of the main body, direct maintenance of specific areas inside the control cabinet is achieved, avoiding the problem of operators having to lean into the cabinet to operate; at the same time, the ventilation mesh on the maintenance doors and the top exhaust assembly form a heat dissipation channel, allowing external air to enter from the side and hot air to be exhausted from the top, forming a bottom-up airflow circulation. This application achieves precise local maintenance through the structural design of double-sided maintenance doors, significantly improving maintenance efficiency and operational safety; at the same time, the optimized airflow channel design improves the heat dissipation effect, ensuring stable operation of electrical equipment at a suitable temperature, effectively solving the problems of difficult maintenance and insufficient heat dissipation of traditional control cabinets.

[0072] Similar parts between the embodiments provided in this application can be referred to mutually. The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
