[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 4 The figure shows the first embodiment of the modular distribution network switch cabinet of the present invention.

[0022] The modular distribution network switch cabinet in this embodiment includes: a bottom cabinet 1, a middle cabinet 2 and a top cabinet 3 assembled into one body; a plurality of groups of lateral telescopic air duct assemblies 5, which are respectively installed on the inner side surfaces of the bottom cabinet 1, the middle cabinet 2 and the top cabinet 3; a plurality of groups of top air duct assemblies 4, which are respectively installed on the top cabinet 3, and between the bottom cabinet 1 and the middle cabinet 2 and between the middle cabinet 2 and the top cabinet 3, the plurality of groups of top air duct assemblies 4 and the plurality of groups of lateral telescopic air duct assemblies 5 are correspondingly inserted and connected; and a plurality of electric control flow guide assemblies 7, which are correspondingly installed at the top position of any group of lateral telescopic air duct assemblies 5, and the other opposite ends of the plurality of electric control flow guide assemblies 7 are correspondingly connected with one end of the plurality of groups of top air duct assemblies 4.

[0023] Among them, by separately controlling the working states of multiple electrically-controlled air guide components 7, the on and off states of multiple groups of lateral telescopic air guide duct components 5 and / or the on and off states of multiple groups of top air guide duct components 4, air diversion and heat dissipation are performed individually or simultaneously at different positions of each cabinet.

[0024] In specific implementation, a bottom air inlet 13 is provided at the bottom of the bottom cabinet 1, a filter screen 14 is installed outside the bottom air inlet 13, and a temperature sensor is installed on any set of lateral telescopic air guide pipe assemblies.

[0025] The laterally telescopic air guide tube assembly 5 includes: a guide tube body 51, a first extension tube 52 slidably sleeved on the bottom of the guide tube body 51, a second extension tube 53 slidably sleeved on the bottom of the first extension tube 52, a guide rail 54, an electric control screw rod 55 installed inside the guide rail 54, and a lifting block 56 installed on the second extension tube 53, and the lifting block 56 is connected to the electric control screw rod 55.

[0026] Wherein: the electric-controlled screw rod 55 is rotated to make the lifting block 56 rise and fall along the guide rail 54, and the guide rail 54 links the second extension tube 53 to extend and retract relative to the first extension tube 52, and / or the first extension tube 52 to extend and retract relative to the guide tube body 51, so as to connect or separate the bottom of the lateral telescopic airway tube assembly 5 with the other opposite end of the top airway tube assembly 4.

[0027] During implementation, the function of the laterally telescopic air guide tube assembly 5 is: in conjunction with the electrically controlled air guide, the electrically controlled screw rod 55 controls the lifting block 56 to lift and slide along the guide rail 54 by rotating, and drives the second extension tube 53 to link the first extension tube 52 and the second extension tube 53 to be lifted or lowered.

[0028] In order to cooperate with the bottom connection, the upper exhaust pipe position of the top air guide assembly 4 has an air guide connecting pipe 41 that protrudes upward and cooperates with the second extension pipe 53. After the second extension pipe 53 descends, it will be sleeved on the upper opening position of the air guide connecting pipe 41, so that the air inside the top air guide assembly of the lower cabinet can be directly drawn into the top air guide assembly of the upper cabinet, thereby not affecting the internal temperature of the middle cabinet 2 or the top cabinet 3 on the upper cabinet.

[0029] Preferably, in order to cooperate with the limiting and control, the outer surfaces of the guide tube body 51 and the first extension tube 52 are provided with a side tubular structure 10, and the inner sides of the upper and lower openings of the first extension tube 52 and the second extension tube 53 are provided with an integral limiting sealing ring 11, and a rubber sealing ring is installed on the inner side of the limiting sealing ring 11. During implementation, the limiting sealing ring 11 is sealed at the bottom when it is raised, and is sealed at the top when it is lowered, thereby ensuring the sealing of the connection end.

[0030] Furthermore, the electrically-controlled flow guide assembly 7 includes: a flow guide shell 71, centrifugal guide blades 72 installed inside the flow guide shell 71, and an embedded motor 73 for controlling the centrifugal guide blades 72, wherein: the lateral air inlet of the flow guide shell 71 is connected to the guide tube body 51 through an arc-shaped exhaust pipe, and the outer exhaust port of the flow guide shell 71 is connected to the lateral air inlet of the top air guide tube assembly 4.

[0031] During implementation, the embedded motor 73 controls the centrifugal guide blades 72 to rotate at high speed, and then draws hot air from the guide pipe body 51 into the guide cover 71 through the arc-shaped exhaust pipe, and then discharges it into the top air guide pipe assembly 4 through the outer exhaust port. At the same time, after the second extension pipe 53 descends, it will be sleeved on the upper end opening of the bottom air inlet, so that the outside air can be directly drawn into the upper layer, and the air inside the middle cabinet 2 or the top cabinet 3 of the upper layer can be directly replaced and guided.

[0032] Furthermore, a ventilation port 8 is provided at one end of the bottom of each group of top air guide tube assemblies 4 , and an electric control cover assembly 9 for controlling the opening and closing state of the ventilation port 8 is installed at the position of the ventilation port 8 .

[0033] Among them, the electric control cover assembly 9 includes: an external flip cover 91 movably installed on the outside of the top air guide assembly 4 and an electric control support rod 92 located on the inner wall of the ventilation port 8. The protruding end of the electric control support rod 92 passes through the ventilation port 8 and is movably assembled with the inner side of the external flip cover 91.

[0034] During implementation, the electric control support rod 92 controls the external flip cover plate 91 to flip and adjust by extension and contraction, thereby adjusting the opening and closing state of the ventilation port 8.

[0035] The purpose of opening the ventilation port 8 is: when the internal power consumption is relatively low and the heat generation is relatively low, directly open the ventilation port 8 of each layer, so as to increase the size of the heat dissipation port on the top, thereby performing passive heat dissipation.

[0036] In this embodiment, the modular distribution network switch cabinet can be operated in a variety of operating modes during specific implementation, for example:

[0037] The first operation mode: when passive low-energy heat dissipation is adopted, the lateral telescopic air guide assembly 5 is retracted upward, the bottom opening is raised to the highest position, and then the electric control air guide assembly 7 is slow and low-power or does not rotate, and then the ventilation port 8 at the lower end of the top air guide assembly 4 is opened. The bottom cabinet 1, the middle cabinet 2 and the top cabinet 3 are connected inside, and at this time, the hot air at the lower position rises to the upper cabinet through the ventilation port 8, and then rises layer by layer in this way.

[0038] The second operating mode: when the heat dissipation inside a single cabinet is too high, the temperature sensor detects local high temperature and adopts active designated position heat dissipation. At this time, the lateral telescopic air duct assembly 5 extends downward, and the bottom opening drops to the lowest position, connecting with the bottom air inlet 13. At this time, the electric control flow guide assembly 7 inside the cabinet that needs heat dissipation is operated at high speed, and then the external air is directly passed through the lateral telescopic air duct assembly 5 and introduced into the designated cabinet to complete the fixed-point heat dissipation.

[0039] The third operating mode: When the heat dissipation inside all cabinets is very high, the temperature sensor detects high temperature, and active heat dissipation is adopted. The electrically controlled air guide component 7 runs at high speed and then draws the external air directly into the bottom cabinet 1, and then draws it into the middle cabinet 2 along the top air guide duct component 4, and then draws it out from bottom to top in sequence.

[0040] The fourth operating mode: when the lateral telescopic air duct assembly 5 is raised and lowered regularly, when it is raised and lowered to a specified height, the temperature sensor detects local high temperature, and the lifting and lowering of the lateral telescopic air duct assembly 5 is stopped. At this time, a local high-height air extraction and heat dissipation method is adopted to prevent the temperature inside the cabinet from continuously affecting the upper components.
