[0021] As shown in FIG. 1, it is an embodiment one of the modular distribution network switch cabinet of the present application. Figures 1-4 As shown in FIG. 1, it is an embodiment one of the modular distribution network switch cabinet of the present application.

[0022] The modular distribution network switch cabinet in the embodiment includes: a bottom cabinet body 1, a middle cabinet body 2 and a top cabinet body 3 assembled as a whole; a plurality of groups of lateral telescopic air guide pipe assemblies 5, each of which is arranged on the inner side of the bottom cabinet body 1, the middle cabinet body 2 and the top cabinet body 3; a plurality of groups of top air guide pipe assemblies 4, each of which is arranged on the top cabinet body 3, between the bottom cabinet body 1 and the middle cabinet body 2, and between the middle cabinet body 2 and the top cabinet body 3, and the plurality of groups of top air guide pipe assemblies 4 and the plurality of groups of lateral telescopic air guide pipe assemblies 5 are correspondingly and continuously inserted; and a plurality of electrically controlled flow guide assemblies 7, each of which is arranged at the top of any one of the plurality of groups of lateral telescopic air guide pipe assemblies 5, and the other end of each of the plurality of electrically controlled flow guide assemblies 7 is connected to one end of each of the plurality of groups of top air guide pipe assemblies 4.

[0023] In the embodiment, the working state of the plurality of electrically controlled flow guide assemblies 7, the open and closed state of the plurality of groups of lateral telescopic air guide pipe assemblies 5 and / or the open and closed state of the plurality of groups of top air guide pipe assemblies 4 are controlled respectively, so as to separately or simultaneously guide the flow and dissipate the heat at different positions of each cabinet body.

[0024] In the embodiment, the bottom of the bottom cabinet body 1 is provided with a bottom air inlet 13, a filter screen 14 is arranged on the outer side of the bottom air inlet 13, and a temperature sensor is arranged on any one of the plurality of groups of lateral telescopic air guide pipe assemblies.

[0025] The lateral telescopic air guide pipe assembly 5 includes a guide pipe body 51, a first extension pipe 52 slidably sleeved at the bottom of the guide pipe body 51, a second extension pipe 53 slidably sleeved at the bottom of the first extension pipe 52, a guide rail 54, an electrically controlled screw rod 55 arranged in the guide rail 54, and a lifting block 56 arranged on the second extension pipe 53, the lifting block 56 being connected to the electrically controlled screw rod 55.

[0026] In the embodiment, rotating the electrically controlled screw rod 55 causes the lifting block 56 to be adjusted up and down along the guide rail 54, the guide rail 54 is linked to the second extension pipe 53 to be telescoped relative to the first extension pipe 52, and / or the first extension pipe 52 is telescoped relative to the guide pipe body 51, so as to connect or separate the bottom of the lateral telescopic air guide pipe assembly 5 to the other end of the top air guide pipe assembly 4.

[0027] In implementation, the lateral telescopic air duct assembly 5 functions to adjust the air flow in coordination with the electric control. The electric control screw rod 55 controls the lifting block 56 to ascend or descend along the guide rail 54 to adjust the sliding, and drives the second extension pipe 53 to link the first extension pipe 52 and the second extension pipe 53 to ascend or descend.

[0028] In order to coordinate the bottom communication, the upper end of the top air duct assembly 4 is provided with the air communication pipe 41 protruding upward to cooperate with the second extension pipe 53. When the second extension pipe 53 descends, it is sleeved on the upper end opening of the air communication pipe 41, so that the air in the inside of the top air duct assembly of the lower cabinet body can be directly sucked into the inside of the top air duct assembly of the upper cabinet body, thereby not affecting the temperature in the inside of the middle cabinet body 2 or the top cabinet body 3 of the upper cabinet body.

[0029] Preferably, in order to coordinate the limiting and control, the guide pipe body 51 and the first extension pipe 52 are both provided with the lateral tubular structure 10 on the outer side, and the inner side of the upper and lower end openings of the first extension pipe 52 and the second extension pipe 53 is provided with the limiting sealing ring 11 in an integrated structure, and the inner side of the limiting sealing ring 11 is provided with the rubber sealing ring. In implementation, the limiting sealing ring 11 seals at the bottom when it ascends and seals at the top when it descends, thereby ensuring the sealing of the connecting end.

[0030] Further, the electric control air flow assembly 7 comprises the air flow cover 71, the centrifugal air flow vane 72 arranged in the air flow cover 71, and the embedded motor 73 for controlling the centrifugal air flow vane 72, wherein the lateral air inlet of the air flow cover 71 is communicated with the guide pipe body 51 through the arc-shaped air suction pipe, and the outer side air outlet of the air flow cover 71 is communicated with the lateral air inlet of the top air duct assembly 4.

[0031] In implementation, the embedded motor 73 controls the centrifugal air flow vane 72 to rotate at high speed, then the hot air is sucked from the guide pipe body 51 into the air flow cover 71 through the arc-shaped air suction pipe, and then is discharged into the inside of the top air duct assembly 4 through the outer side air outlet. At the same time, when the second extension pipe 53 descends, it is sleeved on the upper end opening of the bottom air inlet, so that the external air can be directly sucked into the upper layer to replace the air in the inside of the middle cabinet body 2 or the top cabinet body 3 of the upper cabinet body.

[0032] Further, the bottom of any one of the top air duct assemblies 4 is provided with the air exchange opening 8, and the air exchange opening 8 is provided with the electric control cover plate assembly 9 for controlling the opening and closing state of the air exchange opening 8.

[0033] The electric control cover plate assembly 9 comprises an external turnover cover plate 91 movably mounted on the outside of the top guide air pipe assembly 4 and an electric control support rod 92 located on the inner wall of the air exchange port 8, and the extended end of the electric control support rod 92 is movably assembled with the inner side of the external turnover cover plate 91 through the air exchange port 8.

[0034] In the implementation, the electric control support rod 92 controls the turnover and adjustment of the external turnover cover plate 91 through extension and retraction, thereby adjusting the opening and closing state of the air exchange port 8.

[0035] The opening of the air exchange port 8 is to directly open the air exchange port 8 of each layer when the internal power consumption is relatively low and the heat generation is also relatively low, so as to increase the size of the heat dissipation port at the top and thereby perform passive heat dissipation.

[0036] The modular network distribution switch cabinet in the embodiment can move in multiple operation modes in the implementation, for example:

[0037] The first operation mode is that when passive low-power-consumption heat dissipation is adopted, the lateral telescopic guide air pipe assembly 5 is retracted upward, the bottom opening is lifted to the highest position, then the electric control guide assembly 7 is slowly rotated at low power consumption or not, and then the air exchange port 8 at the lower end of the top guide air pipe assembly 4 is opened. The inside of the bottom cabinet body 1, the middle cabinet body 2 and the top cabinet body 3 are connected, at this time, the hot air at the low position is lifted to the inside of the upper cabinet body through the air exchange port 8, and then the above process is repeated layer by layer.

[0038] The second operation mode is that when the heat dissipation of a single cabinet body is too high and the temperature sensor detects local high temperature, active specified position heat dissipation is adopted, at this time, the lateral telescopic guide air pipe assembly 5 is extended downward, the bottom opening is lowered to the lowest position and connected with the bottom air inlet 13, at this time, the electric control guide assembly 7 in the cabinet body which needs to be cooled is rotated at high speed, then the external air is directly introduced into the specified cabinet body through the lateral telescopic guide air pipe assembly 5, and the specified position heat dissipation is completed.

[0039] The third operation mode is that when the heat dissipation of all cabinet bodies is high and the temperature sensor detects high temperature, active heat dissipation is adopted, the electric control guide assembly 7 is rotated at high speed, then the external air is directly introduced into the bottom cabinet body 1, and then introduced into the middle cabinet body 2 along the top guide air pipe assembly 4, and then sequentially introduced from the bottom to the top.

[0040] The fourth operation mode is that the lateral telescopic guide air pipe assembly 5 is periodically lifted and lowered, when the lateral telescopic guide air pipe assembly 5 is lifted to a specified height and the temperature sensor detects local high temperature, the lifting and lowering of the lateral telescopic guide air pipe assembly 5 is stopped, at this time, the local height air extraction heat dissipation mode is adopted to avoid that the temperature in the cabinet body continuously increases to affect the components at the upper part.

[0041] The modular power distribution switch cabinet has the following beneficial effects: the modular power distribution switch cabinet comprises a bottom cabinet body, a middle cabinet body and a top cabinet body assembled into one; a plurality of groups of lateral telescopic air guide pipe assemblies are respectively arranged on the inner side surfaces of the bottom cabinet body, the middle cabinet body and the top cabinet body; a plurality of groups of top air guide pipe assemblies are respectively arranged on the top cabinet body, between the bottom cabinet body and the middle cabinet body and between the middle cabinet body and the top cabinet body, the plurality of groups of top air guide pipe assemblies and the plurality of groups of lateral telescopic air guide pipe assemblies are correspondingly and continuously inserted; and a plurality of electrically controlled flow guide assemblies are respectively arranged at the top positions of the lateral telescopic air guide pipe assemblies, and the opposite ends of the plurality of electrically controlled flow guide assemblies are respectively connected to one end of the plurality of groups of top air guide pipe assemblies, wherein: by respectively controlling the working states of the plurality of electrically controlled flow guide assemblies, the open and closed states of the plurality of groups of lateral telescopic air guide pipe assemblies and / or the open and closed states of the plurality of groups of top air guide pipe assemblies, the different positions of the cabinet bodies can be separately or simultaneously guided to flow and dissipate heat, the different positions of the cabinet bodies can be separately or simultaneously guided to flow and dissipate heat, the heat dissipation effect is improved, and the structure is simple and reasonable, which is beneficial to safe and stable operation.
