Description

Technical Field

[0001] This utility model relates to the field of electrical control cabinet technology, and in particular to a detachable and modular electrical control cabinet. Background Technology

[0002] In today's era of rapid industrial automation and intelligent development, the importance of electrical control cabinets as the core control hub of electrical systems is self-evident. From traditional manufacturing to emerging smart factories, from urban power distribution facilities to various complex industrial production lines, electrical control cabinets are widely used in various fields, undertaking the critical responsibility of controlling, protecting, and monitoring the operation of electrical equipment.

[0003] Existing detachable and modular electrical control cabinets mostly employ basic bolted or snap-fit ​​structures. For heat dissipation, they largely rely on traditional natural convection or mechanically assisted ventilation. Their operating principle is primarily based on the connection of electrical circuits and the setting of control logic. Various switching devices, such as circuit breakers and contactors, control the on / off state of the circuit, thereby manipulating the connected electrical equipment. Measuring instruments monitor parameters such as current and voltage in the circuit in real time, while protective electrical devices quickly activate in case of overload, short circuit, or other abnormal conditions, cutting off the circuit to ensure the safety of equipment and personnel.

[0004] However, in practical use, the ventilation and protection systems of traditional electrical control cabinets have revealed serious drawbacks. In many industrial settings, such as cement plants and coal mines, the air is filled with a large amount of dust, fibers, and metal shavings. Because the ventilation openings of traditional electrical control cabinets often lack effective protection, these impurities can easily enter the cabinet through air convection. The dust gradually accumulates on the surfaces of electrical components. When heat sinks and fan blades are covered in dust, the heat generated by the components is difficult to dissipate, causing them to operate at high temperatures for extended periods, accelerating aging, and even leading to burnout. Furthermore, when dust accumulates at wiring terminals or plug-in interfaces, contact resistance increases, signal transmission is interfered with and becomes unstable, and power contact failures can occur, severely affecting the normal operation of the equipment and reducing the stability and reliability of the entire system. Therefore, a detachable and modular electrical control cabinet is proposed to address these problems. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] The outer wall of the guide post is slidably connected to the inner wall of the main body, the outer wall of the main body is fixedly connected to a fixing block, and the inner wall of the fixing block is rotatably connected to a rotating post.

[0015] As a further description of the above technical solution:

[0016] A pull rod is fixedly connected to the outer wall of the rotating column, and a second spring is provided on the outer wall of the pull rod. One end of the second spring is fixedly connected to the outer wall of the pull rod, and the other end of the second spring is fixedly connected to the outer wall of the main body.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the pull rod is rotatably connected to a fixed frame, the fixed frame has a sliding groove inside, a sliding block is slidably connected to the inner wall of the fixed frame, and a sliding rod is fixedly connected to the outer wall of the sliding block;

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the guide post slides against the inner wall of the main body and then engages with the buckle and slot, effectively intercepting dust and impurities entering the electrical control cabinet. This prevents unprotected dust, fibers, metal shavings, and other impurities from entering the cabinet with the airflow. Accumulation of these impurities on the surface of electrical components can cause dust to cover heat sinks or fan blades, hindering heat dissipation and keeping components at high temperatures for extended periods, accelerating aging or even causing burnout. Furthermore, dust accumulation at terminals or plug-in interfaces increases contact resistance, leading to unstable signal transmission or power contact failure. This design ensures the ventilation efficiency of the cooling fan or natural convection within the cabinet, improving equipment stability.

[0025] 2. In this utility model, the connecting rod drives the buckle block to move, and then the buckle block releases the engagement with the hook, achieving the effect of quickly disassembling the outer shell. This avoids the need to unscrew each bolt individually during maintenance, which requires the use of professional tools and takes a long time for each disassembly, and there is a risk of bolt loss or stripping. Therefore, the outer shell can be disassembled quickly, increasing maintenance efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figures 1-3This utility model provides an embodiment of a detachable and modular electrical control cabinet, comprising a main body 1, an outer shell 2 on the outer wall of the main body 1, a detachable assembly on the outer wall of the main body 1, and a ventilation opening 3 inside the outer shell 2 for air circulation between the inside and outside of the electrical control cabinet to achieve heat dissipation. A dustproof assembly, including a dustproof net 4, is provided on the outer wall of the outer shell 2. The dustproof net 4 filters dust and debris from the air to prevent them from entering the electrical control cabinet, thus protecting the electrical components. The outer wall of the dustproof net 4 is located on the outer wall of the outer shell 2, and a guide post 11 is fixedly connected to the outer wall of the dustproof net 4. The guide post 11 is used to position the dustproof net 4 during installation and to guide the dustproof net 4 during installation. The support increases the stability of the dustproof net 4 during installation. The outer wall of the guide column 11 is slidably connected to the inner wall of the main body 1. The main body 1 has a slot 5 inside. The inner wall of the dustproof net 4 is slidably connected to the handle 6. The outer wall of the handle 6 is provided with a reset component. The outer wall of the handle 6 is rotatably connected to the connecting arm 9. The outer wall of the connecting arm 9 is rotatably connected to the locking block 10. The outer wall of the locking block 10 is rotatably connected to the inner wall of the dustproof net 4. The outer wall of the locking block 10 is slidably connected to the inner wall of the slot 5. When the handle 6 is pulled, the locking block 10 is rotated through the connecting arm 9, causing it to disengage from the slot 5, achieving the effect of quick disassembly of the dustproof net 4. During installation, simply insert the dustproof net 4, and the locking block 10 will automatically lock into the slot 5 under the action of the spring 8, achieving quick installation.

[0037] Reference Figures 1-7The reset assembly includes a fixing plate 7, whose inner wall is fixedly connected to the outer wall of the handle 6. A spring 8 is sleeved on the outer wall of the handle 6. One end of the spring 8 is fixedly connected to the inner wall of the dustproof mesh 4, and the other end is fixedly connected to the outer wall of the fixing plate 7. When the handle 6 is pulled, the spring 8 is stretched by force. After being released, the spring 8 resets, causing the handle 6 to return to its original position, thus achieving the effect of automatic reset of the handle 6. The disassembly assembly includes a hook 22, which is used to engage with the buckle block 21 to achieve quick connection and disassembly of the outer shell 2 and the main body 1, achieving the effect of convenient installation and maintenance. The outer wall is fixedly connected to the outer wall of the outer shell 2. A guide post 23 is fixedly connected to the outer wall of the outer shell 2. The outer wall of the guide post 23 is slidably connected to the inner wall of the main body 1. The guide post 23 works with the hook 22 for precise positioning, achieving quick installation and preventing the outer shell 2 from shifting. A fixing block 12 is fixedly connected to the outer wall of the main body 1. A rotating column 13 is rotatably connected to the inner wall of the fixing block 12. A pull rod 14 is fixedly connected to the outer wall of the rotating column 13. A spring 15 is provided on the outer wall of the pull rod 14. One end of the spring 15 is fixedly connected to the outer wall of the pull rod 14, and the other end of the spring 15 is fixedly connected to the outer wall of the main body 1. When pulled... When lever 14 is pulled, spring 15 is stretched by force. After being released, spring 15 returns to its original position, causing lever 14 to return to its original position, thus ensuring that the latching block 21 and hook 22 are always engaged, preventing the latching block 21 from falling off the outer wall of hook 22. A fixing frame 16 is rotatably connected to the outer wall of lever 14. A sliding groove 17 is provided inside the fixing frame 16. A sliding block 18 is slidably connected to the inner wall of the fixing frame 16. A sliding rod 19 is fixedly connected to the outer wall of the sliding block 18. The outer wall of the sliding rod 19 is slidably connected to the inner wall of the sliding groove 17. The sliding block 18 slides linearly through the cooperation of the sliding rod 19 and the sliding groove 17, achieving control. The effect of moving the latching block 21 is achieved by connecting the connecting rod 20 fixedly connected to the outer wall of the sliding block 18, and slidingly connecting the outer wall of the connecting rod 20 to the inner wall of the fixing frame 16. A spring 24 is sleeved on the outer wall of the connecting rod 20. One end of the spring 24 is fixedly connected to the outer wall of the sliding block 18, and the other end of the spring 24 is fixedly connected to the inner wall of the fixing frame 16. The latching block 21 is fixedly connected to one end of the connecting rod 20. The latching block 21 and the hook 22 engage with each other. When the latching block 21 and the hook 22 engage, the spring 24 is in a compressed state, providing a stable clamping force to prevent the outer shell 2 from loosening and achieve a stable connection.

[0038] Working principle: When the electrical control cabinet is working, first pull handle 6. Pulling handle 6 moves the fixing plate 7, which in turn compresses spring 8. Then, the movement of handle 6 rotates the connecting arm 9, which in turn rotates the locking block 10. Next, the locking block 10 slides onto the inner wall of the slot 5. Then, release handle 6. The return of spring 8 resets the fixing plate 7, which in turn moves handle 6. The movement of handle 6 rotates the connecting arm 9, which in turn engages the locking block 10 with the slot 5. Finally, the dust filter 4 blocks the entry of... Dust and impurities inside the vent 3 are intercepted. When the dust filter 4 needs to be disassembled and cleaned, simply pull the handle 6. Pulling the handle 6 will rotate the connecting arm 9. Then, the rotation of the connecting arm 9 will cause the locking block 10 to disengage from the locking slot 5, thus completing the disassembly of the dust filter 4. This prevents dust, fibers, metal shavings and other impurities in the air from entering the cabinet with the airflow without protection. These impurities accumulate on the surface of electrical components, causing dust to cover the heat sink or fan blades, hindering heat dissipation, keeping the components at a high temperature for a long time, accelerating aging or even burning out. In addition, dust accumulation at the wiring terminals or plug interfaces increases contact resistance, leading to unstable signal transmission or power contact failure.

[0039] When disassembling the outer casing 2, first pull the lever 14. Pulling the lever 14 causes the fixing bracket 16 to rotate, which stretches the second spring 15. Then, the rotation of the fixing bracket 16 causes the sliding rod 19 to slide on the inner wall of the slide groove 17. The movement of the sliding rod 19 causes the sliding block 18 to move, which in turn causes the connecting rod 20 to move. The movement of the connecting rod 20 then causes the latching block 21 to move, which then releases the latching block 21 from the hook 22. After the latching block 21 is released, the third spring 24 returns to its original position. When installing the outer casing 2, simply engage the hook 22 and the latching block 21, and then release them. Pull rod 14 is reset by the rebound of spring 15, which in turn moves the fixing frame 16. The movement of the fixing frame 16 then causes the sliding rod 19 to slide on the inner wall of the slide groove 17. The sliding of the sliding rod 19 causes the sliding block 18 to move, which in turn compresses spring 24. The movement of the sliding block 18 then moves the connecting rod 20. Subsequently, the movement of the connecting rod 20 causes the buckle block 21 and the hook 22 to engage. This avoids the need to unscrew each bolt of the traditional bolted housing 2 during maintenance, which requires the use of professional tools, is time-consuming, and carries the risk of bolt loss or stripping.
