DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0026] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0027] Example 1 Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides an armored removable metal-enclosed switchgear, including a switch cabinet 100, the switch cabinet 100 being a mounting carrier, and forming an enclosed space for accommodating electrical components therein; The support mechanism 300 is fixedly mounted on the bottom of the switch cabinet 100 and includes a buffer assembly 305 located between the support mechanism 300 and the switch cabinet 100 to buffer the impact of external vibration on the electrical components. The ventilation and heat dissipation mechanism 200 is installed on the side of the switch cabinet 100 and is connected to the internal space of the switch cabinet 100. It is used to extract the heat from the switch cabinet 100. The ventilation and heat dissipation mechanism 200 includes a heat conduction component 203. The heat conduction component 203 is arranged on the inner side of the ventilation and heat dissipation mechanism 200, corresponding to the heating element in the switch cabinet 100, and is used to conduct the heat generated by the heating element to the ventilation and heat dissipation mechanism 200.

[0028] The support mechanism 300 is fixed to the bottom of the switch cabinet 100, and the buffer component 305 it contains is located between the support mechanism 300 and the switch cabinet 100. When the equipment is subjected to external vibration or impact, the buffer component 305 absorbs the impact force through its own deformation, reduces the impact of vibration on internal electrical components, and ensures the stability of component connection.

[0029] Specifically, a load-bearing frame plate 102 is provided inside the switch cabinet 100 , a plurality of air-permeable nets 103 are provided on the bottom outer wall of the switch cabinet 100 , and a cabinet door 101 is provided on the front outer wall of the switch cabinet 100 .

[0030] When in use, the ventilation and heat dissipation mechanism 200 is installed on the side of the switch cabinet 100 and is connected to the internal space. The heat flow conduction component 203 is set corresponding to the heating element, which can conduct the heat generated by the heating element to the ventilation and heat dissipation mechanism 200, and then the heat is discharged through the air exchange between the ventilation and heat dissipation mechanism 200 and the external environment; at the same time, the air permeable net 103 at the bottom of the switch cabinet 100 can introduce external cold air to form air circulation and avoid internal heat accumulation.

[0031] Example 2 Reference Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, mounting openings 104 are opened on both sides of the outer wall of the switch cabinet 100, and the ventilation and heat dissipation mechanism 200 is arranged inside the mounting opening 104. The ventilation and heat dissipation mechanism 200 also includes a heat conducting plate 201, which is snap-fitted and fixed inside the mounting opening 104. A plurality of ventilation nets 202 are provided on the surface of the heat conducting plate 201.

[0032] During operation, the heat generated by the electrical components inside the switch cabinet 100 will diffuse to the surroundings. The heat conducting plate 201 is in direct contact with the internal space of the switch cabinet 100, and uses its own good thermal conductivity to absorb heat and transfer it to the ventilation and heat dissipation mechanism 200. At the same time, the multiple ventilation nets 202 on the surface of the heat conducting plate 201 form an air flow channel, so that the hot air inside the switch cabinet 100 can enter the ventilation and heat dissipation mechanism 200 through the ventilation nets 202, and then exchange air with the external environment through the ventilation and heat dissipation mechanism 200 to discharge the heat, thereby reducing the internal temperature of the switch cabinet 100 and avoiding heat accumulation.

[0033] Specifically, the heat conduction component 203 is installed on the inner wall of the heat conducting plate 201 , and a partition 204 is installed at one end of the heat conduction component 203 . Heat dissipation holes 205 are opened on the surface of the partition 204 near the four edges.

[0034] The heat dissipation holes 205 are arranged on all sides, so that an air flow guiding channel is formed at the inner edge of the switch cabinet 100, which is convenient for gas exchange and thus facilitates the removal of internal heat flow.

[0035] Furthermore, the heat flux conduction component 203 includes an aluminum alloy card frame 2031, which is installed between the heat conducting plate 201 and the partition 204. The two ends of the aluminum alloy card frame 2031 are respectively fitted with the heat conducting plate 201 and the partition 204. The interior of the aluminum alloy card frame 2031 is provided with guide plates 2033 distributed vertically and equidistantly.

[0036] The two ends of the aluminum alloy frame 2031 are respectively attached to the heat conducting plate 201 and the partition plate 204. With the excellent thermal conductivity of the aluminum alloy, the internal heat of the switch cabinet 100 absorbed by the heat conducting plate 201 is efficiently transferred to the outside. The guide boxes 2032 horizontally arranged at the upper and lower ends further converge and guide the hot air flow to move toward the heat dissipation area of ​​the ventilation and heat dissipation mechanism, thereby accelerating the transfer of heat to the outside.

[0037] Among them, the upper and lower ends of the aluminum alloy card frame 2031 are horizontally provided with a guide box 2032, and the interior of the aluminum alloy card frame 2031 is clamped with an activated carbon adsorption bag.

[0038] When in use, the activated carbon adsorption bag can adsorb dust and moisture in the circulating air, purify the air simultaneously during the heat conduction process, and reduce the impact of dust on internal components.

[0039] Example 3 Reference Figures 1 to 7 , which is the third embodiment of the present invention. Different from the previous embodiment, the support mechanism 300 includes a base plate 301, and side plates 302 are installed on both sides of the surface of the base plate 301. Dust-proof and heat-dissipating nets 303 are provided at adjacent ends of the two side plates 302, and the switch cabinet 100 is arranged on the inner walls of the two side plates 302.

[0040] Two sets of protection are formed by the dustproof heat dissipation net 303 and the air-permeable net 103 at the bottom of the switch cabinet 100, which facilitates heat exchange and reduces the entry of dust.

[0041] Specifically, a mounting groove 304 is formed on the surface of the bottom plate 301 , the buffer assembly 305 is fixed inside the mounting groove 304 , and the top end of the buffer assembly 305 is mounted on the bottom outer wall of the switch cabinet 100 .

[0042] Furthermore, the buffer assembly 305 includes a damping buffer 3051 , which is fixed inside the mounting groove 304 . A buffer spring 3052 is provided on the circumferential outer wall of the damping buffer 3051 , and a pressure plate 3053 is installed on the top of the damping buffer 3051 .

[0043] When the switch cabinet 100 is subjected to external vibration or impact, the impact force is transmitted to the pressure plate 3053 through the bottom of the switch cabinet 100, and then acts on the damping buffer 3051 and the buffer spring 3052 mounted on its circumferential outer wall. The buffer spring 3052 absorbs part of the impact force through its own elastic deformation, and the damping buffer 3051 uses its damping characteristics to slow down the transmission speed and amplitude of the impact force. The two work together to effectively attenuate vibration energy, reduce the impact of external vibration on the internal electrical components of the switch cabinet 100, and ensure the stable operation of the components.

[0044] The same cross plate 3054 is installed on the outer walls of the plurality of pressure plates 3053 , and the cross plate 3054 is fixed on the bottom outer wall of the switch cabinet 100 .

[0045] When in use, the setting of the cross plate 3054 enables multiple buffer components 305 to form an overall force-bearing system, avoiding force concentration on a single buffer component, while enhancing the lateral stability of the buffer structure, ensuring that each buffer component functions synchronously, uniformly attenuating vibration energy, and further improving the vibration protection effect of the switch cabinet 100 and internal electrical components.

[0046] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
