Description

Technical Field

[0001] This utility model relates to the field of mining control cabinet technology, and in particular to a quick-release sealed operation panel for a mining electric valve control cabinet. Background Technology

[0002] Mining electric valve control cabinets are specifically designed for hazardous environments such as coal mines and non-coal mines. These environments typically contain flammable gases and dust, thus requiring special explosion-proof designs and materials to ensure safety. They are usually made of welded steel plates or die-cast aluminum alloys, with the outer shell having high-pressure electrostatic powder coating. The internal structure is divided into multiple modules, and each switch and electrical component requires isolation and protection. The sealing requirements are higher, the cover and the cabinet have a good seal, and they have undergone rigorous testing.

[0003] Existing electric valve control cabinet buttons are equipped with independent protection devices to prevent internal electric arcs from coming into contact with external dust, gas, etc., and thus posing a safety hazard. However, after long-term use, the external protective components of these buttons are more prone to aging and cracking in harsh working environments. Maintenance and replacement require the disassembly of many parts. Therefore, it is necessary to add an additional operating panel on the outside that is easy to maintain and disassemble and has protective functions. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing a quick-release sealed operation panel for a mining electric valve control cabinet.

[0005] This utility model is achieved through the following technical solution:

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-4The diagram shows a quick-release sealed operating panel for a mining electric valve control cabinet, comprising a control cabinet 1, a pressure device 2, an inner control panel 3, a data display panel 4, operating buttons 5, and an outer panel assembly 6. The pressure device 2 is located outside the control cabinet 1, the inner control panel 3 is fixedly located inside the control cabinet 1, the data display panel 4 and operating buttons 5 are installed and fixed to the inner control panel 3, and the outer panel assembly 6 is located outside the control cabinet 1. The outer panel assembly 6 includes a shield 61, an observation glass 62, an operating panel 63, an operating component 64, and a compression sealing ring 65. The observation glass 62 and the operating panel 63 are installed... The operating component 64 is connected to the operating plate 63 and is installed inside the shield 61. A retaining ring is provided on the outer edge of the inner side of the shield 61. A compression sealing ring 65 is sleeved on the outer side of the retaining ring inside the shield 61. The operating component 64 includes a pressure rod 641, a spring 642, a pressure plate 643, an outer isolation cover 644, and an inner telescopic cover 645. The pressure rod 641 is locked inside the operating plate 63. The pressure plate 643 is fixed to one end of the pressure rod 641. The spring 642 is sleeved on the outer side of the pressure rod 641. The outer isolation cover 644 is locked on the outer side of the operating plate 63. The inner telescopic cover 645 is locked on the inner side of the operating plate 63.

[0025] Specifically, the pressure device 2 includes a mounting base 21, a pressure knob 22, and a pressing plate 23. The mounting base 21 is fixed to the outside of the control cabinet 1. The pressure knob 22 is threaded to the outside of the mounting base 21. The pressing plate 23 is locked inside one side of the mounting base 21. A locking block is provided on one side of the pressing plate 23. A guide groove that cooperates with it is opened inside one side of the mounting base 21. Both ends of the shield 61 are provided with inclined surfaces. A wedge-shaped surface that cooperates with it is provided at the bottom of one end of the pressing plate 23. One end of the spring 642 is fixed to the outside of the operating plate 63, and the other end is fixed to the inside of the pressing plate 643. The spring 642 is located inside the outer isolation cover 644. One end of the pressure rod 641 is located inside the inner telescopic cover 645. One end of the inner telescopic cover 645 is located outside one end of the operating button 5. A sealing groove that cooperates with the inner retaining ring of the shield 61 is opened inside the control cabinet 1. The vertical cross-section of the inner retaining ring of the shield 61 is trapezoidal.

[0026] In this embodiment, the internal control panel 3 inside the control cabinet 1 is equipped with a data display panel 4 and operation buttons 5 that have sealing and protection. After long-term use in harsh environments, in order to ensure its sealing and protection performance, the internal control panel 3 needs to be replaced after a certain period of time. This requires the disassembly and replacement of many parts. Therefore, it is necessary to set an outer panel assembly 6 outside the control cabinet 1, located outside the internal control panel 3. The outer panel assembly 6 not only reduces the contact between the data display panel 4 and operation buttons 5 on the surface of the internal control panel 3 and the harsh external environment, but also slows down the aging of internal rubber parts and improves the safety of use.

[0027] Furthermore, the outer panel assembly 6 is connected to the control cabinet 1 via the pressure device 2. After a compression sealing ring 65 is fitted onto the retaining ring surface on the back of the shield 61, the retaining ring on the back of the shield 61 is engaged in the sealing groove inside the control cabinet 1. Then, the pressure knob 22 is screwed inward, causing the pressure knob 22 to press one end of the pressure plate 23. This causes the bottom bevel of the forward-moving pressure plate 23 to press against the bevels at both ends of the shield 61, thus achieving the effect of fixing the shield 61. During operation, the observation glass 62 facilitates the observation of the internal data display panel 4. Pressing the pressure plate 643 causes the spring 642 to compress and contract, the outer isolation cover 644 to compress and contract, and the inner telescopic cover 645 to stretch outward, causing the end of the pressure rod 641 to operate the operation button 5. After the operation is completed, the spring 642 assists the pressure rod 641 to return to its original position. One end of the inner telescopic cover 645 and the outer isolation cover 644 are both sealed and fixed to the shield 61, thereby ensuring airtightness and improving safety in use.
