Description

Technical Field

[0001] This utility model relates to the field of low-voltage switchgear, specifically a dual-circuit incoming low-voltage switchgear for a fresh air shaft air compressor room. Background Technology

[0002] An air compressor room is a dedicated space for the centralized installation and operation of air compressors and their auxiliary equipment. It is the core area of ​​the compressed air supply system in industrial production. Its main functions are to provide a safe and stable operating environment for the air compressors, ensure a continuous supply of compressed air, and meet the needs of equipment maintenance, noise control, and heat dissipation.

[0003] To improve indoor air quality, existing air compressor rooms typically use ventilation systems with fresh air shafts, allowing the low-pressure cabinets within the room to dissipate heat. However, the low-pressure cabinets used in existing fresh air shaft air compressor rooms still have the following problems during use: Existing low-voltage switchgear internal components (such as busbars and contacts) generate localized high temperatures during long-term operation, while the metal surface of the switchgear remains relatively cool, creating a temperature difference. When the ambient humidity is high, water vapor in the air condenses into water droplets on the switchgear surface. These droplets enter the switchgear through the inlet and outlet ports of the dual-circuit incoming cables, which is especially noticeable during the rainy season or when the groundwater level rises. In switchgear with good sealing, moisture accumulates on the bottom surface inside the switchgear, making cleaning difficult. Therefore, it is necessary to develop a new type of dual-circuit incoming low-voltage switchgear for air compressor rooms in ventilation shafts for use in the existing low-voltage switchgear field. Utility Model Content

[0004] To address the shortcomings of existing technologies, where moisture droplets form and enter the cabinet through the inlet and outlet ports of the dual-circuit incoming cables, causing significant inconvenience for cleaning, this invention proposes a new type of dual-circuit incoming low-voltage cabinet for air compressor rooms in ventilation shafts.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-circuit incoming low-voltage switchgear for a new air shaft air compressor room, comprising: The main body of the dual-circuit incoming low-voltage switchgear has a collection box at the bottom. Extension blocks are fixedly mounted on both symmetrical sides of the collection box. An assembly block is fixedly mounted on one end of each extension block. The assembly blocks are located on both sides of the dual-circuit incoming low-voltage switchgear and each assembly block is provided with an insertion port. The positioning mechanism includes two sets of fixing blocks, which are fixedly assembled to the sides of the dual-circuit incoming low-voltage switchgear body. Each set of fixing blocks consists of two blocks, with the two blocks in each set located on one side of the assembly block. Guide rods are symmetrically fixed between the two fixing blocks in each set. Sliding blocks are movably mounted on each of the two guide rods, and connecting blocks are fixedly mounted on each sliding block. The connecting blocks are located on one side of the fixing blocks, and a limit block is fixedly mounted on one end of each connecting block. Insertion blocks are fixedly mounted on each limit block, and the insertion blocks are inserted into the corresponding insertion ports on the assembly block.

[0006] Preferably, each of the insert blocks is provided with a slot, the slot is located on one side of the assembly block, each of the limiting blocks is fixedly assembled with an installation block, and each of the installation blocks is fixedly assembled with an operating block at one end.

[0007] Preferably, the operating block has a telescopic cavity inside, a traction port on the surface of the operating block, the traction port communicating with the telescopic cavity, a telescopic spring fixedly mounted on the telescopic cavity, and a push plate fixedly mounted on one end of the telescopic spring.

[0008] Preferably, a toggle block is fixedly mounted on the push plate, and the toggle block is movably assembled with the traction port.

[0009] Preferably, a plug rod is fixedly mounted on the push plate, the plug rod movably passes through the operating block, and the operating block is inserted into the slot.

[0010] Preferably, the dual-circuit incoming low-voltage switchgear body has an internal mounting cavity and a communication port at the bottom.

[0011] Preferably, the connecting port is connected to the mounting cavity, and the connecting port is located inside the collection base box.

[0012] Preferably, the bottom of the dual-circuit incoming low-voltage switchgear is fixedly equipped with support legs, which are located on the outside of the collection base box.

[0013] The advantages of this utility model are: This invention features a collection box fitted to the bottom of the dual-circuit incoming low-voltage switchgear body. The insertion port on the assembly block is positioned on one side of the block. Moving the actuating block causes the push plate to retract the telescopic spring, moving the insertion rod away from the slot on the insertion block. This pulls the sliding block along the guide rod, causing the sliding block to move the limiting block on the connecting block until the insertion block engages with the insertion port on the assembly block, with the slot positioned on one side of the assembly block. Releasing the actuating block allows the push plate to engage the insertion rod with the slot under the elastic force of the telescopic spring. This increases the stability of the collection box at the bottom of the dual-circuit incoming low-voltage switchgear body, facilitating collection operations. Water droplets enter the mounting cavity of the dual-circuit incoming low-voltage switchgear body through the inlet and outlet ports of the dual-circuit incoming cables, then fall into the collection box for collection. The collection box can be easily disassembled, making the collected water droplets easier to handle and improving operational efficiency. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a dual-circuit incoming low-voltage switchgear for a fresh air shaft air compressor room. (Refer to...) Figure 1 and Figure 4 as well as Figure 5A new type of dual-circuit low-voltage switchgear for air compressor rooms in ventilation shafts includes a main body 10 with dual-circuit incoming low-voltage switchgear. A collection box 11 is mounted at the bottom of the main body 10. Extension blocks 21 are fixedly mounted on both symmetrical sides of the collection box 11. Assembly blocks 22 are fixedly mounted on one end of each extension block 21. The assembly blocks 22 are located on both sides of the main body 10 with insertion ports 23. Positioning mechanisms 20 are mounted on both symmetrical sides of the collection box 11. The positioning mechanisms 20 include fixed... Two sets of fixing blocks 2000 are fixedly assembled to the side of the dual-circuit incoming low-voltage switchgear body 10. Each set of fixing blocks 2000 consists of two blocks, and the two fixing blocks 2000 in each set are located on one side of the assembly block 22. Guide rods 2001 are symmetrically fixed between the two fixing blocks 2000 in each set. Sliding blocks 2002 are movably mounted on each of the two guide rods 2001. Connecting blocks 2003 are fixedly mounted on each sliding block 2002. The connecting blocks 2003 are located on one side of the fixing blocks 2000. On one side, a limiting block 2004 is fixedly mounted on one end of the connecting block 2003. A plug 2005 is fixedly mounted on each limiting block 2004. The plug 2005 is inserted into the socket 23 on the assembly block 22. Each plug 2005 has a slot 2006 located on one side of the assembly block 22. An installation block 2007 is fixedly mounted on each limiting block 2004. An operating block 2008 is fixedly mounted on one end of each installation block 2007. The operating block 2008 has a telescopic cavity 2009 inside. The surface of the operating block 2008 is provided with a traction port 2010, which communicates with the telescopic cavity 2009. A telescopic spring 2011 is fixedly mounted on the telescopic cavity 2009. A push plate 2012 is fixedly mounted on one end of the telescopic spring 2011. A toggle block 2013 that moves in the traction port 2010 is fixedly mounted on the push plate 2012. An insertion rod 2014 is fixedly mounted on the push plate 2012. The insertion rod 2014 movably passes through the operating block 2008, and the operating block 2008 is inserted into the slot 2006.

[0019] In this utility model, the collection base box 11 is attached to the bottom of the dual-circuit incoming low-voltage cabinet body 10, so that the socket 23 on the assembly block 22 is located on one side of the socket block 2005. The actuating block 2013 is moved, so that the push plate 2012 drives the telescopic spring 2011 to retract. At this time, the insertion rod 2014 moves away from the slot 2006 of the socket block 2005, and the sliding block 2002 moves on the guide rod 2001, so that the sliding block 2002 drives the limiting block 2004 on the connecting block 2003 to move until the socket block 2005 is inserted into the socket 23 on the assembly block 22, and the slot 2006 is located on one side of the assembly block 22. The actuating block 2013 is released, and under the elastic force of the telescopic spring 2011, the push plate 2012 drives the insertion rod 2014 to insert into the slot 2006, so that the stability of the collection base box 11 at the bottom of the dual-circuit incoming low-voltage cabinet body 10 is increased, and the collection operation is convenient.

[0020] Reference Figure 1 and Figure 3 The dual-circuit incoming low-voltage switchgear body 10 has an installation cavity 12 inside. The bottom of the dual-circuit incoming low-voltage switchgear body 10 has a communication port 13 that communicates with the installation cavity 12. The communication port 13 is located inside the collection box 11. The bottom of the dual-circuit incoming low-voltage switchgear body 10 is fixedly equipped with a support leg 30, which is located outside the collection box 11.

[0021] In this invention, water droplets enter the mounting cavity 12 of the dual-circuit low-voltage switchgear body 10 through the inlet and outlet ports of the dual-circuit incoming cable, and then fall from the mounting cavity 12 into the collection box 11 for collection.

[0022] Working principle: The collecting base box 11 is attached to the bottom of the dual-circuit incoming low-voltage switchgear body 10, so that the socket 23 on the assembly block 22 is located on one side of the plug block 2005. The actuating block 2013 is moved, causing the push plate 2012 to retract the telescopic spring 2011. At this time, the plug rod 2014 moves away from the slot 2006 of the plug block 2005, pulling the sliding block 2002 to move on the guide rod 2001. This causes the sliding block 2002 to move the limiting block 2004 on the connecting block 2003 until the plug block 2005 is inserted into the socket 23 on the assembly block 22, and the slot 2006 is located... On one side of assembly block 22, release the actuating block 2013. Under the elastic force of the telescopic spring 2011, the push plate 2012 drives the insertion rod 2014 to insert into the slot 2006. This increases the stability of the collection box 11 at the bottom of the dual-circuit incoming low-voltage cabinet body 10, facilitating collection operations. Water droplets enter the mounting cavity 12 of the dual-circuit incoming low-voltage cabinet body 10 along the inlet and outlet of the dual-circuit incoming cable. The water droplets fall from the mounting cavity 12 into the collection box 11 for collection. By easily disassembling the collection box 11, the water droplets collected by moisture condensation are easy to handle, improving operational efficiency.
