The part of the air inlet 1041 arranged inside the frame 101 is installed with a filter net, and the inside of the filter net is filled with a desiccant or a silica gel drying layer.

[0070] Operation process:

[0071] After the electrical components are installed in the area inside the closed cavity 2042, the wires of the electrical components are passed through the wire plate 2047 into the interior of the threading cavity 2048 and are connected to the external circuit through the threading cavity 2048 and the connecting tube 105. At this time, the top of the wire plate 2047 is sealed by the threading cavity 2048, the bottom of the wire plate 2047 is sealed by the support column 2041, and the back of the wire plate 2047 is sealed by the mounting plate 204. The side of the wire plate 2047 facing the opening 103 is not sealed. The branch rope 203 is then passed through the perforation on the surface of the isolation plate 201. A rubber ring is provided inside the perforation so that the perforation is in movable contact with the branch rope 203 through the fixed rubber ring inside the perforation, thereby achieving movable isolation of the perforation relative to the branch rope 203. The insertion rod 20111 is then passed through the upper through-block 2011 and the opening at the front end of the branch rope 203 and then connected to the lower through-block 2011. The upper, middle and lower parts of the outer side of the isolation plate 201 are all connected with the branch rope 203.

[0072] Then, the isolation plate 201 is moved along the guide column 202 through the perforations at its four corners between the opening 103 and the cabinet door 102, and the control driving source 20121 is started, so that the control driving source 20121 drives the baffle 20122 to rotate, and the baffle 20122 is driven by the control driving source 20121 to rotate into the inside of the opening 103, so that the left and right sides of the opening 103 are symmetrically blocked by the control driving source 20121 and the baffle 20122, so that the isolation plate 201 is manually placed into the inside of the opening 103, so that the isolation plate 201 1 contacts the baffle 20122. At this time, the movable plate 206 and the counterweight block 2063, under their own weight, pull the isolation plate 201 toward the inside of the through block 2011 through the main rope 2031 and the branch rope 203, and the isolation plate 201 is blocked by the baffle 20122, so that the isolation plate 201 is pulled and clamped inside the opening 103. At this time, the rubber layer wrapped around the outside of the isolation plate 201 contacts the rubber layer wrapped around the inner contour of the opening 103, so that the isolation plate 201 blocks the internal space of the installation cavity 1011.

[0073] Then, the cabinet door 102 is closed on the surface of the frame 101, and the handle on the surface of the cabinet door 102 is rotated so that the horizontal plate of the handle on the inner side of the cabinet door 102 is clamped into the notch of the clamping block on the right side of the installation cavity 1011, so that the rubber layer on the opposite side of the cabinet door 102 and the frame 101 is adhered to the surface of the frame 101, and then the rubber layer on the back of the cabinet door 102 is in contact with the frame 101 to achieve a primary closure, and the rubber layer wrapped inside the opening 103 and the rubber layer on the outside of the isolation plate 201 are in contact and sealed to achieve a secondary closure, thereby achieving a secondary closure through the two The first-level sealing makes the first-level sealing serve as the first barrier to prevent rainwater from directly impacting the cabinet body and prevent large particles of dust from entering the interior of the equipment, while the second-level sealing serves as the second barrier, thereby reducing the trace water vapor and fine dust that penetrates through the door gap of the cabinet door 102, thereby reducing the water vapor and dust inside the equipment through double-layer isolation. When the baffle 20122 blocks the isolation plate 201 so that the isolation plate 201 is located inside the opening 103, the isolation plate 201 pulls the movable plate 206 to the top of the discharge chamber 1012 through the branch rope 203 and the main rope 2031.

[0074] It should be noted that in order to improve the stability of the isolation plate 201 installed inside the opening 103, multiple control drive sources 20121 can be set on the back of the isolation plate 201, so that the multiple control drive sources 20121 are set in the upper, middle and lower parts of the isolation plate 201, and the baffles 20122 controlled by the multiple control drive sources 20121 are used to support the isolation plate 201 inside the opening 103.

[0075] After the cabinet door 102 is closed, the diaphragm pump inside the pumping chamber 205 is started, so that the diaphragm pump inside the pumping chamber 205 draws out the air at the bottom of the pumping tube 2051 and discharges it to the outside of the frame 101 through the exhaust pipe 2052, and the diaphragm pump generates suction at the bottom of the installation chamber 1011 through the pumping tube 2051, so that the diaphragm pump draws the air outside the air inlet 1041 into the interior of the installation chamber 1011, and the suction generated at the bottom of the installation chamber 1011 guides the air through the top of the installation chamber 1011 to the bottom of the installation chamber 1011, thereby cooling the air guided through the interior of the installation chamber 1011. In order to reduce the humidity and dust of the air entering the interior of the installation chamber 1011, a filter can be installed at the part of the air inlet 1041 located in the installation chamber 1011 and a desiccant or a silica gel drying layer can be filled inside the filter to reduce the dust and water vapor inside the air from entering the interior of the installation chamber 1011.

[0076] Solution for early warning scenario one: the air inlet 1041 is set at the top of the installation cavity 1011, which can increase the water level line of accumulated water in extreme climates entering the installation cavity 1011, and the bottom surface of the pumping tube 2051 is set in the middle of the trigger member 2062, and the detection contact of the trigger member 2062 is located on the top surface of the trigger member 2062. At this time, the isolation plate 201 is located inside the opening 103, so that when water accumulates inside the installation cavity 1011, the water flow reaching the bottom of the pumping tube 2051 can be pumped out of the installation cavity 1011 through the discharge pipe 2052, thereby preventing the accumulated water from slowly flooding into the closed cavity 2042 inside the installation plate 204, reducing the damage to the electrical components inside the closed cavity 2042, and the cross-section of the connecting sleeve 2061 at the bottom of the installation cavity 1011 is inclined, which is convenient for gathering and sucking the accumulated water inside the installation cavity 1011.

[0077] Solution for early warning scenario two: In extreme weather, when the amount of water poured into the installation cavity 1011 is greater than the amount of water pumped out by the diaphragm pump in the pumping cavity 205, the water flow will submerge the top surface of the trigger member 2062, causing the trigger member 2062, which is preferably a resistive water level sensor, to operate. Then, when the water flow overflows the two probes on the top surface of the trigger member 2062, the conductivity of the water will cause the probes to conduct and change the resistance of the two, so that the PLC chip inside the trigger member 2062 will collect the resistance change signal of the probes. It can also be connected to the local area network for cloud alarm flooding warning. When the resistance change signal of the probes is obtained, the PLC will send an action signal to the control drive source 20121 to drive the control drive source 20121 to rotate. The trigger member 2062 and the control drive source 20121 can be connected by wires or by Bluetooth. In the above process, you can refer to Xiaomi's water leakage detection sensor. When detecting a water leak, it drives the motor on the water valve to rotate, so that the valve wrench connected to the motor through the swing arm rotates with the motor to close the valve.

[0078] When the control driving source 20121 drives the baffle 20122 to rotate and finally rotates the baffle 20122 to the surface of the frame 101, the baffle 20122 releases the blocking of the isolation plate 201, so that the isolation plate 201 releases the pulling displacement restriction of the movable plate 206, so that the movable plate 206 falls under the gravity of the counterweight block 2063 at its bottom and its own weight, and under the design that the weight of the isolation plate 201 is lighter than the sum of the weight of the movable plate 206 and the counterweight block 2063, when the movable plate 206 falls, it drives the branch rope 203 and the main rope 2031 to pull the isolation plate 201 to move along the guide column 202, so that the surface of the isolation plate 201 The plug rod 20151 is inserted into the socket 20431 on the outside of the mounting plate 204, thereby closing the first closed chamber 2013 and the second closed chamber 2042. The rubber layers on the surfaces of the first closed chamber 2013 and the second closed chamber 2042 are pulled into contact and fit by the movable plate 206 through the branch rope 203 and the main rope 2031. The movable plug-in connection of the plug rod 20151 and the socket 20431 causes the isolation plate 201 to move toward the mounting plate 204 along the guide column 202, thereby completing the sealing of the electrical equipment inside the second closed chamber 2042 on the surface of the mounting plate 204, thereby reducing the impact of the rising water level on the electrical equipment inside the second closed chamber 2042.

[0079] And through the reversing of the guide wheel 2044 and the downward movement of the movable plate 206 along the support column 2041, it is ensured that the isolation plate 201 is relatively stable and close to the mounting plate 204, so that when the closed chamber 2042 and the closed chamber 1 2013 are docked, the plug rod 20151 is inserted into the corresponding socket 20431 to complete the locking. Of course, in order to share the instability of the main rope 2031 moving downward to pull multiple branch ropes 203, the branch ropes 203 can be connected to different positions of the independent main rope 2031 and the movable plate 206, so that the main rope 2031 only pulls the independent branch rope 203 connected to it to move , and the upper, middle and lower parts of the isolation plate 201 are connected by multiple branch ropes 203. When the movable plate 206 moves downward, the pulling force on the isolation plate 201 through the main rope 2031 and the branch rope 203 can be relatively uniform. Of course, a single branch rope 203 can also be used to connect the branch rope 203 to the middle part of the isolation plate 201, so that the main rope 2031 is pulled along the movable plate 206 to the single branch rope 203 located in the middle of the isolation plate 201 and moves, so that the isolation plate 201 moves along the guide columns 202 at its four corners, and the closed contact between the closed cavity 1 2013 and the closed cavity 2 2042 can also be achieved.

[0080] In addition, the downward movement of the movable plate 206 will also cause the accumulated water on the top to fall into the space where the movable plate 206 is lowered, that is, the downward movement of the movable plate 206 will cause the connecting sleeve 2061 to be pulled and expanded to form a conical cavity, so that the water level of the accumulated water at the bottom of the installation cavity 1011 will be drawn downward, thereby avoiding that during the closing process of the closing cavity 1 2013 and the closing cavity 2 2042, excessive accumulated water will be pushed between the two, thereby further improving the safety of the closure of the closing cavity 2 2042 and the closing cavity 1 2013, and reducing the possibility that the electrical components inside the closing cavity 2 2042 will be affected by the accumulated water.

[0081] When the closing chamber 2042 and the closing chamber 1 2013 are closed, the water flow accumulated on the top of the expanded connecting sleeve 2061 will increase the weight of the movable plate 206 and the counterweight block 2063, so that the weighted movable plate 206 can be pulled to the branch rope 203 and the main rope 2031 more stably, and the plug rod 20151 is maintained in the state of being inserted into the socket 20431. The plug rod 20151 is composed of two special-shaped rods with triangular blocks on the top. When the plug rod 20151 is inserted into the socket 20431, the inner wall of the socket 20431 will squeeze the triangular block of the plug rod 20151 to move inward. When the plug rod 20151 continues to be inserted into the inside of the socket 20431, the squeezed plug rod 20151 will eventually be 20151 unfolds at the back of the socket 20431, realizing the locking of the socket 20431 by the plug rod 20151, so that the closed closed cavity 1 2013 and the closed cavity 2 2042 realize the closed protection of the internal components of the closed cavity 2 2042, providing accidental protection for the power supply control cabinet in subsequent extreme weather. In this process, the movable plate 206 moves downward by its own weight, and the closed self-locking of the closed cavity 1 2013 and the closed cavity 2 2042 is mechanically completed, reducing the involvement of electrical equipment, ensuring the stability of the closed locking of the closed cavity 1 2013 and the closed cavity 2 2042 in the subsequent accumulation of water, thereby providing a protection basis for extending the power supply time in extreme climates.

[0082] In summary: multi-level sealing is used to reduce the risk of excessive moisture and dust entering the interior of the equipment during use, and the pumping chamber 205 is provided for suction, and the air inlet 1041 is provided for cooling the equipment inside the installation chamber 1011. At the same time, the pumping chamber 205 can also clean up the accumulated water that enters the installation chamber 1011 under extreme climates, and the trigger movable plate 206 provided can be pulled to the closing chamber 1 2013 under its own weight to close the closing chamber 2 2042 where the electrical components are installed, thereby reducing the possibility of accumulated water flooding into the closing chamber 2 2042 and damaging the electrical components, providing a protection plan for electrical cabinets under extreme climates, and in this process, electrical equipment is less involved, and after locking, it relies entirely on mechanical locking, thereby achieving energy saving and stability of the protection plan.
