Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to an energy-saving and explosion-proof power distribution cabinet. Background Art

[0002] A power distribution cabinet is a metal cabinet used to distribute and control electricity. It contains various switches, circuit breakers, relays, measuring instruments and other components to distribute electrical energy to different circuits or equipment safely and reliably.

[0003] If the switch contacts of the control switch in the distribution cabinet are in poor contact, oxidized or severely worn, an arc will be generated between the contacts when power is turned on, generating a lot of heat. If the arc lasts too long or the current is too large, it will cause the switch and the surrounding insulation materials to burn or even explode.

[0004] However, existing power distribution cabinets usually adopt a single-layer cabinet structure and lack a horizontal lateral pressure relief design. This means that when an internal fault (such as an arc fault or explosion) causes a sudden increase in pressure, the pressure is released mainly along the front or side of the cabinet. This one-way pressure relief method has significant defects: first, the strong pressure shock wave will directly act on the front of the cabinet, which may cause the cabinet door to deform or splash, causing direct personal injury to the operator. Secondly, the shock wave will also cause serious impact damage to surrounding equipment, causing equipment damage, functional failure, and even chain reactions, expanding the scope of the accident. Summary of the invention

[0005] The present application provides an energy-saving explosion-proof power distribution cabinet, which has the function of guiding the energy generated by the explosion to be released upward, thereby minimizing the damage to personnel caused by the explosion shock wave and fragments.

[0015] By adopting the above technical solution, when an explosion occurs, the interlayer space shrinks, squeezing the third baffle and the fourth baffle, causing the diamond-shaped enclosure structure to deform in a controllable manner; this deformation process effectively absorbs the impact energy of the explosion and converts kinetic energy into elastic potential energy and friction energy; the diamond-shaped structure makes full use of the interlayer space to maximize the buffering effect; compared with traditional filling materials, this controllable deformation diamond structure can absorb energy more effectively when subjected to high impact forces, and due to its design and material properties, it ensures that the deformation is predictable and controllable, avoiding structural failure.

[0016] Preferably, the first baffle plate and the second baffle plate are connected to the first connecting block via a first spring, and the third baffle plate and the fourth baffle plate are connected to the second connecting block via a second spring.

[0018] Preferably, a mounting block is fixedly mounted on the inner wall of the enclosure structure, and an alarm with a push switch is provided on the mounting block, and the alarm is located on a slidable side of the third connecting block.

[0019] By adopting the above technical solution, when the above enclosure structure is deformed, the third connecting block will move toward the push switch of the alarm and push the push switch, thereby activating the alarm; this design does not require complex electronic components or sensors, has a simple structure, and low energy consumption, and the alarm is automatically triggered by passive deformation of the structure, without the need for an additional power supply or control system.

[0027] 2. When the internal control switch of this energy-saving explosion-proof distribution cabinet explodes, the interlayer space shrinks, squeezing the third baffle and the fourth baffle, causing the diamond-shaped enclosure structure to deform in a controllable manner; this deformation process effectively absorbs the impact energy of the explosion and converts kinetic energy into elastic potential energy and friction energy; the diamond structure makes full use of the interlayer space to maximize the buffering effect; compared with traditional filling materials, this controllable deformation diamond structure can absorb energy more effectively when subjected to high impact force, and due to its design and material properties, it ensures that the deformation is predictable and controllable, avoiding structural failure.

DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0031] The present invention discloses an energy-saving explosion-proof power distribution cabinet, such as Figure 1 and Figure 2 As shown, it includes a base 1 and a control switch 2, a fixed leg 3 is fixedly installed on the bottom of the base 1, a back panel 4, a first side panel 5, a second side panel 6 and a door panel 7 are fixedly installed on the upper surface of the base 1, the back panel 4, the first side panel 5, the second side panel 6 and the door panel 7 form a semi-enclosed enclosure structure above the base 1, the control switch 2 is located inside the enclosure structure, a movably arranged top panel 8 is provided on the top of the enclosure structure, a first positioning plate 9 and a second positioning plate 10 are symmetrically arranged on the bottom of the top panel 8, a limiting groove 11 is formed between the first positioning plate 9 and the second positioning plate 10, the two limiting grooves 11 are respectively matched with the first side panel 5 and the second side panel 6, a positioning block is provided on the first positioning plate 9, and the positioning block is matched with the positioning groove arranged on the inner side of the first positioning plate 9.

[0032] like Figure 1 and Figure 2As shown, the hazard caused by the explosion is reduced by means of pressure relief. When the internal pressure of the distribution cabinet exceeds the set value, the top plate 8 moves upward in the limit grooves 11 of the first positioning plate 9 and the second positioning plate 10, thereby releasing the internal pressure. Compared with releasing the pressure in the horizontal direction, the pressure released upward can more effectively reduce the damage to the surrounding personnel and equipment. Through the preset pressure relief path, the explosion pressure is guided to be released upward instead of spreading to the surrounding, thereby minimizing the destructive power of the explosion. Thus, the explosion fragments and shock waves are prevented from causing harm to the surrounding personnel. In addition, the degree of damage to the distribution cabinet itself and the surrounding equipment is reduced.

[0033] like Figure 1 and Figure 2 As shown, the interior of the enclosure structure is provided with a first buffer plate 12 and a second buffer plate 13 parallel to the first side plate 5 and the second side plate 6, and the interior of the enclosure structure is provided with a third buffer plate 14 parallel to the back plate 4. The inner surface of the third buffer plate 14 is provided with a slide rail 15, and the first buffer plate 12 and the second buffer plate 13 are slidably connected to the slide rail 15 via a slider 16.

[0034] like Figure 1 and Figure 2 As shown, when an explosion occurs inside, the first buffer plate 12, the second buffer plate 13 (parallel to the first side plate 5 and the second side plate 6, respectively) and the third buffer plate 14 (parallel to the back plate 4) will absorb part of the impact force and reduce the impact of the explosion pressure on other components of the distribution cabinet (such as the control switch 2, etc.); and the design of the slide rail 15 and the slider 16 can guide the first buffer plate 12 and the second buffer plate 13 to move along a predetermined direction under the explosion pressure; this can ensure that the buffer plate effectively absorbs the impact force and prevents the first side plate 5, the second side plate 6 and the back plate 4 from being deformed or damaged due to the explosion, thereby more effectively protecting the internal components; this helps to more effectively release the explosion energy along a preset path instead of letting it spread irregularly inside.

[0035] like Figure 1 and Figure 2 As shown, the multi-layer buffering of the first buffer plate 12, the second buffer plate 13 and the third buffer plate 14 and the guide of the slide rail 15 can more effectively absorb and disperse the explosion energy, improve the explosion-proof capability of the distribution cabinet; and can effectively protect the internal control switch 2 and other electronic components from damage caused by the explosion impact, thereby extending their service life.

[0036] like Figure 1 and Figure 2 As shown, in summary, this design further improves the explosion-proof performance and reliability of the distribution cabinet by adding buffer and guide mechanisms, providing more effective protection for the internal equipment.

[0037] like Figure 1 and Figure 2As shown, the third buffer plate 14, the first buffer plate 12 and the second buffer plate 13 are enclosed to form a mounting structure with a "C"-shaped cross-section, and a sandwich is formed between the outer surface of the mounting structure and the inner surface of the enclosure structure. A buffer component 17 for reducing the impact of the explosion on the enclosure structure is arranged inside the sandwich. The "C"-shaped structure itself provides a certain rigidity and strength, which can resist the shock wave generated by the explosion; when an explosion occurs, the shock wave first acts on the mounting structure with a "C"-shaped cross-section enclosed by the third buffer plate 14, the first buffer plate 12 and the second buffer plate 13; the addition of the buffer component 17 further delays and disperses the propagation speed and energy of the shock wave.

[0038] like Figure 3 As shown, specifically, the buffer assembly 17 includes a first connecting block 1701 arranged on the outer surface of the mounting structure and a second connecting block 1702 arranged on the inner surface of the maintenance structure, the first connecting block 1701 is rotatably provided with a first baffle 1703 and a second baffle 1704, the second connecting block 1702 is rotatably provided with a third baffle 1705 and a fourth baffle 1706, the first baffle 1703 and the third baffle 1705 are rotatably connected through a third connecting block 1707, the second baffle 1704 and the fourth baffle 1706 are rotatably connected through a fourth connecting block 1708, and the first baffle 1703, the second baffle 1704, the third baffle 1705 and the fourth baffle 1706 form a cross section The enclosure structure is a diamond-shaped structure, which is located inside the interlayer. When an explosion occurs and causes the internal space of the interlayer to shrink, the third baffle 1705 and the fourth baffle 1706 will be squeezed, causing the diamond-shaped enclosure structure to deform. This deformation process absorbs most of the energy of the explosion impact and converts the kinetic energy into elastic potential energy or friction energy. The diamond-shaped enclosure can effectively utilize the interlayer space and maximize the buffering effect. Compared with simple filling materials, this controllable deformable diamond structure can more effectively absorb the explosion impact energy, especially when subjected to a large impact force. Due to the design of the structure and the selection of materials, this deformation is predictable and controllable, which can avoid sudden failure of the structure.

[0039] like Figure 3 As shown, the first baffle 1703 and the second baffle 1704 are connected to the first connecting block 1701 via a first spring, and the third baffle 1705 and the fourth baffle 1706 are connected to the second connecting block 1702 via a second spring.

[0040] like Figure 3As shown, the first spring and the second spring are preloaded in the initial state to store a certain amount of elastic potential energy; this preload can make the diamond structure in a stressed state in the initial state, thereby improving the response speed and energy absorption efficiency of the system; when the explosion impact occurs, the first spring and the second spring are further compressed to absorb part of the impact energy.

[0041] like Figure 3 As shown, moreover; the elastic characteristics of the first spring and the second spring can effectively buffer the violent vibration caused by the explosion impact and reduce the instantaneous impact of the impact force on the structure; the compression and rebound process of the first spring and the second spring can effectively delay the time of energy release and reduce the peak value of the impact load.

[0042] like Figure 3 As shown, under the impact of the explosion, the compression of the first spring and the second spring will assist the deformation of the diamond structure, further improving the energy absorption capacity; the rebound of the first spring and the second spring will assist the recovery of the diamond structure, reducing the permanent deformation of the structure.

[0043] like Figure 3 As shown, the addition of the first spring and the second spring can significantly improve the energy absorption efficiency of the system, especially when dealing with a smaller impact force, the buffering effect of the first spring and the second spring is more obvious.

[0044] like Figure 3 As shown, a mounting block 18 is fixedly installed on the inner wall of the enclosure structure, and an alarm 19 with a push switch is provided on the mounting block 18. The alarm 19 is located on the sliding side of the third connecting block 1707. When the above-mentioned enclosure structure is deformed, the third connecting block 1707 will move toward the push switch of the alarm 19 and push the push switch to activate the alarm 19. This design does not require complex electronic components or sensors, has a simple structure, and low energy consumption, and the alarm 19 is automatically triggered by the passive deformation of the structure, without the need for an additional power supply or control system. Once the enclosure structure is deformed, the alarm 19 can sound an alarm in time, providing time for personnel evacuation and emergency processing.

[0045] like Figure 3 As shown, the first connecting block 1701 and the second connecting block 1702 are connected by a telescopic member 20, and the telescopic member 20 includes a sub-rod 2002 arranged on the first connecting block 1701 and a sleeve 2001 arranged on the second connecting block 1702, the sub-rod 2002 is located inside the sleeve 2001, and a buffer spring is provided between the sub-rod 2002 and the sleeve 2001.

[0046] like Figure 3As shown, the first connecting block 1701 and the second connecting block 1702 are telescopically connected through the sub-rod 2002 and the sleeve 2001, allowing a certain relative displacement between them; the sub-rod 2002 slides in the sleeve 2001, and the buffer spring is installed between the sub-rod 2002 and the sleeve 2001; when relative displacement occurs between the first connecting block 1701 and the second connecting block 1702, the buffer spring will be compressed or stretched, absorbing part of the energy, thereby slowing down the relative movement and preventing severe impact or collision between the connecting parts; this makes the connection more stable and also extends the service life of the telescopic part 20.

[0047] like Figure 4 As shown, a fire extinguishing assembly 21 is provided inside the interlayer, and the fire extinguishing assembly 21 includes a bellows 2101, and the inner and outer surfaces of the bellows 2101 are sprayed with a fire retardant coating, one end of the bellows 2101 is connected to the outer surface of the mounting structure, and the other end of the bellows 2101 is connected to the inner surface of the enclosure structure, and the surface of the mounting structure is provided with a weak portion 2102, which is a circular structure and is located at the position of the bellows 2101, and the inside of the bellows 2101 is provided with a fire extinguishing material 2103.

[0048] like Figure 4 As shown, the system is based on a trigger mechanism of pressure changes in the interlayer space; under normal circumstances, the fire extinguishing material 2103 in the bellows 2101 is in a static state; when the internal space of the interlayer is squeezed; for example, the temperature and pressure increase caused by a fire, the internal space of the bellows 2101 will be compressed; this compression force will act on the fire extinguishing material 2103 inside the bellows 2101, forcing the fire extinguishing material 2103 to squeegee through the pre-set circular structural weak area, thereby entering the internal space of the enclosure structure that needs to be protected, and finally covering the fire source and achieving fire extinguishing; the fire-retardant coating protects the bellows 2101 itself from rupture or failure at high temperatures, thereby ensuring the reliability of fire extinguishing.

[0049] like Figure 4 As shown, the system does not require external power or manual operation, and is completely triggered passively by the change in the mezzanine space pressure; once the mezzanine space pressure exceeds the set value, the system will automatically start fire extinguishing; once triggered, the fire extinguishing material 2103 can be quickly sprayed to the fire source location, shortening the fire extinguishing time and reducing fire losses; the system structure is relatively simple and easy to install and maintain; the fire extinguishing material 2103 acts directly on the fire source, and the fire extinguishing efficiency is high.

[0050] like Figure 4 As shown, in summary, this design provides an efficient, reliable and automated fire extinguishing solution, which is particularly suitable for occasions requiring passive fire protection; the key lies in using the pressure change in the mezzanine space as a trigger mechanism to achieve automatic, fast and efficient fire extinguishing.

[0051] like Figure 4 As shown, specifically, the fire extinguishing material 2103 is a dry powder fire extinguishing agent; dry powder can effectively interrupt the combustion chain reaction and cool the burning material, thereby achieving the purpose of extinguishing the fire; its fire extinguishing efficiency is relatively high in many cases.

[0052] Working principle: When an explosion occurs inside the distribution cabinet and the pressure generated by the explosion exceeds the set value, the pressure in the horizontal direction will impact the installation structure. When the installation structure is under pressure, the space of its interlayer will become smaller. The buffer component 17 is set to play a role in buffering and pressure relief. At the same time, the buffer component 17 will trigger the switch of the alarm 19. Once the enclosure structure is deformed, the alarm 19 will sound an alarm in time, providing time for personnel evacuation and emergency response.

[0053] On the other hand, when a fire occurs, the temperature and pressure of the interlayer space increase, forcing the fire extinguishing material 2103 to squeeze out through the preset weak area of ​​the bellows 2101, covering the fire source to extinguish the fire; the fire-retardant coating protects the bellows 2101 from remaining intact at high temperatures, ensuring the reliability of the fire extinguishing process.

[0054] Moreover, when the pressure exceeds the set value, the top plate 8 will move upward along the preset guide rail to release the pressure upward; this vertical pressure relief method is more effective than horizontal pressure relief in reducing the impact on personnel and equipment; it is like a safety valve, controlling the direction and intensity of pressure release to prevent the lateral spread of explosion energy from causing greater damage.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
