[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The following is combined with Figures 1 to 8 This invention describes a high- and low-voltage switchgear and its control method that automatically adjusts temperature and humidity according to the environment.

[0036] In one embodiment, a high- and low-voltage switchgear that self-regulates temperature and humidity according to the environment includes a cabinet, a movable mounting component 200, and a movable locking component 300. The cabinet has a first mounting cavity 110 and a second mounting cavity 120 arranged sequentially from top to bottom. A flow guide channel 140 is provided at the edge of the first mounting cavity 110, with one end extending to the top of the first mounting cavity 110 and the other end communicating with the second mounting cavity 120. A locking cavity 130 is provided at the connection between the second mounting cavity 120 and the flow guide channel 140. The movable mounting component 200... The first mounting cavity 110 is installed horizontally in the second mounting cavity 120; the movable clip 300 is installed vertically in the movable mounting part 200, and the top of the movable clip 300 is used to snap into the snap-fit ​​cavity 130; according to the temperature and humidity signals detected by the temperature and humidity sensors inside and outside the cabinet, the drive unit set on one side of the movable mounting part 200 is started and performs air extraction, drawing in the air from the external environment and then pushing the air out of the cabinet. During the process, the air passes through the movable clip 300, the snap-fit ​​cavity 130, the guide channel 140, the first mounting cavity 110 and the second mounting cavity 120 in sequence.

[0037] Specifically, temperature and humidity sensors are installed both inside and outside the cabinet to detect the internal temperature and humidity and compare them with the external environment. Based on the comparison of the temperature and humidity signals, the drive mechanism can be activated to extract air, allowing air from the external environment to flow through the cabinet, balancing the internal temperature and dehumidifying the interior. Before activating the drive mechanism, the movable mounting part 200 is inserted into the second mounting cavity 120. Since the top of the movable locking part 300 normally protrudes from the movable mounting part 200, when the movable locking part 300 is activated... When the movable mounting component 200 is installed to a certain extent, the end of the movable locking component 300 will be inserted into the locking cavity 130. At this time, the driving component can be started. The air in the external environment will flow through the movable mounting component 200, the movable locking component 300, the guide channel 140, the first mounting cavity 110 and the second mounting cavity 120 in sequence, and finally re-enter the external environment. According to the temperature distribution inside the cabinet, the air outlet position of the guide channel 140 can be adjusted, thereby changing the air flow position of the first mounting cavity 110 inside the cabinet.

[0038] The second mounting cavity 120 is connected to the first mounting cavity 110 through the first air inlet 121, and the second mounting cavity 120 is connected to the external environment through the first air outlet 122.

[0039] The aforementioned high and low voltage switchgear that automatically adjusts temperature and humidity based on the environment has temperature and humidity sensors installed both inside and outside the cabinet. These sensors detect the internal temperature and humidity of the cabinet and compare them with the external ambient temperature and humidity. Based on the comparison of the temperature and humidity signals, the drive unit can be activated to extract air, allowing air from the external environment to flow through the cabinet, balancing the internal temperature and dehumidifying the interior. Before activating the drive unit, the movable mounting part 200 is inserted into the second mounting cavity 120. Since the top of the movable locking part 300 normally protrudes from the movable mounting part... Therefore, when the movable mounting component 200 is installed to a certain extent, the end of the movable latch 300 will insert into the latching cavity 130. At this time, the drive component can be activated. Air from the external environment will flow sequentially through the movable mounting component 200, the movable latch 300, the guide channel 140, the first mounting cavity 110, and the second mounting cavity 120, and finally re-enter the external environment. According to the temperature distribution inside the cabinet, the air outlet position of the guide channel 140 can be adjusted, thereby changing the airflow position of the first mounting cavity 110 inside the cabinet. This effectively balances the temperature and dehumidifies the inside of the switch cabinet, avoiding risks caused by temperature and humidity differences.

[0040] In one embodiment, a mounting bracket 160 is installed in the first mounting cavity 110. The front end of the first mounting cavity 110 is set as an open structure and a cabinet door 170 is installed thereon. A sealing plate 150 is provided at the corner of the first mounting cavity 110. The sealing plate 150 and the inner surface of the cabinet form a flow channel 140. The rear end of the second mounting cavity 120 is set as an open structure. The cross-section of the snap-fit ​​cavity 130 is a right-angled triangle structure, and the hypotenuse of the right-angled triangle structure is inclined towards the cabinet door 170.

[0041] Specifically, the cross-section of the guide channel 140 formed by the sealing plate 150 and the inner surface of the cabinet is triangular and located at the corner of the first mounting cavity 110. By setting the snap-fit ​​cavity 130 to have a right-angled triangular cross-section, and the hypotenuse of the right-angled triangular structure is inclined towards the cabinet door 170, when the movable mounting part 200 is installed into the second mounting cavity 120, the end of the movable snap-fit ​​part 300 will snap into the snap-fit ​​cavity 130 and will not be disengaged due to vibration or other factors.

[0042] The sealing plate 150 is provided with multiple guide holes 151 spaced apart, and each guide hole 151 is provided with a removable plug to control the air outlet position of the guide channel 140.

[0043] In one embodiment, the movable mounting component 200 includes a mounting base 210, a first vent pipe 220, a second vent pipe 230, and a connecting pipe 240. The mounting base 210 is inserted from the open structure end of the second mounting cavity 120. The first vent pipe 220 and the second vent pipe 230 are both located inside the mounting base 210. One end of the first vent pipe 220 and the second vent pipe 230 penetrates the side of the mounting base 210. The ends of the first vent pipe 220 and the second vent pipe 230 that penetrate the mounting base 210 are connected by the connecting pipe 240. A driving component is provided at the connecting pipe 240 for driving gas flow.

[0044] Specifically, the movable clip 300 is installed inside the mounting base 210. A spring 250 is provided between the bottom end of the movable clip 300 and the inner bottom surface of the mounting base 210. When the movable clip 300 is entirely inside the mounting base 210, the end of the second vent pipe 230 abuts against the side of the movable clip 300. When the top of the movable clip 300 rises and is inserted into the snap-fit ​​cavity 130, the end of the second vent pipe 230 communicates with the inside of the movable clip 300.

[0045] In one embodiment, the mounting base 210 includes a side-opening box 211 and guide ribs 213. One end of the opening of the side-opening box 211 faces the same direction as the open structure end of the second mounting cavity 120. The top of the side-opening box 211 has an upper opening 212. Two guide ribs 213 are respectively arranged on both sides of the side-opening box 211. A positioning ring 214 is provided on the bottom surface of the side-opening box 211, and the bottom end of the spring 250 is engaged in the positioning ring 214.

[0046] Specifically, the guide rib 213 is set in a semi-circular structure, and the flat end of the semi-circular structure is attached to the inner side of the side-opening box 211. The upper opening 212 is used to install the movable clip 300, and the movable clip end can protrude out of the upper opening 212 and clip into the clip cavity 130.

[0047] In one embodiment, the first venting fitting 220 includes a first fixed pipe 221, an annular plate 222, a connector 223, and a filter block 224. The first fixed pipe 221 is arranged laterally, and one end passes through the unopened side of the side-opening box 211. One end of the connector 223 is inserted into the first fixed pipe 221, and the other end of the connector 223 is connected to the inner ring of the annular plate 222 and connected to the annular plate 222. The end of the connector 223 away from the annular plate 222 contracts toward the central axis, and the filter block 224 is installed in the connector 223.

[0048] The second vent pipe 230 includes a second fixed pipe 231 and an annular gasket 233; the second fixed pipe 231 is arranged horizontally, and one end passes through the unopened side of the side-opening box 211, and the other end of the second fixed pipe 231 is provided with a slot 232, which is arranged in an annular structure, and the annular gasket 233 is disposed in the slot 232.

[0049] Specifically, the length of the first fixing tube 221 is greater than the length of the second fixing tube 231. When the movable clip 300 is located inside the side-opening box 211, the side of the movable clip 300 abuts against the ring gasket 233, forming a seal on the second fixing tube 231. When the top of the movable clip 300 protrudes into the snap-fit ​​cavity 130, the second fixing tube 231 communicates with the interior of the movable clip 300.

[0050] In one embodiment, the movable latch 300 includes a rectangular box 310 and an overlapping plate 330. The top surface of the rectangular box 310 is set as a slope 320. The rectangular box 310 is movably latched into the side-opening box 211. The overlapping plate 330 is disposed on one side of the rectangular box 310 facing the opening end of the side-opening box 211. One side of the rectangular box 310 has a rounded corner where it connects to the slope 320. A plurality of second air vents 350 are spaced apart at the rounded corner. The other side of the rectangular box 310 has a second air inlet 340. The rectangular box 310 has first recesses 360 on both sides that match the guide ribs 213, and a second recess 370 at the bottom end that matches the first fixing tube 221.

[0051] In one embodiment, a control method for a high- and low-voltage switchgear that automatically adjusts to ambient temperature and humidity, applied to the high- and low-voltage switchgear that automatically adjusts to ambient temperature and humidity in any of the above embodiments, includes the following steps:

[0052] Based on the temperature and humidity signals detected by the temperature and humidity sensors inside and outside the cabinet, the drive unit is activated and begins to extract air.

[0053] External air flows through the cabinet interior and passes sequentially through movable mounting part 200, movable clip 300, airflow channel 140, first mounting cavity 110 and second mounting cavity 120.

[0054] The air outlet position of the air guide channel 140 is adjusted according to the temperature and humidity signal, thereby changing the air flow path inside the cabinet.

[0055] The control method for high and low voltage switchgear based on the above-mentioned self-regulating temperature and humidity of the environment involves temperature and humidity sensors installed both inside and outside the cabinet to detect the internal temperature and humidity and compare them with the temperature and humidity of the external environment. Based on the comparison of the temperature and humidity signals, the drive unit can be activated to extract air, allowing air from the external environment to flow through the cabinet, balancing the internal temperature and dehumidifying the cabinet. Before activating the drive unit, the movable mounting part 200 is inserted into the second mounting cavity 120. Since the top of the movable locking part 300 normally protrudes from the movable mounting cavity... Mounting component 200 is installed to a certain extent, so the end of the movable locking component 300 will insert into the locking cavity 130. At this time, the drive component can be activated. Air from the external environment will flow sequentially through the movable mounting component 200, the movable locking component 300, the guide channel 140, the first mounting cavity 110, and the second mounting cavity 120, and finally re-enter the external environment. According to the temperature distribution inside the cabinet, the air outlet position of the guide channel 140 can be adjusted, thereby changing the airflow position of the first mounting cavity 110 inside the cabinet. This can effectively balance the temperature and dehumidify the inside of the switch cabinet, avoiding the risks caused by temperature and humidity differences.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
