[0032] The embodiments of the present invention provide a structure and method suitable for rapid installation of a rail transit control box.

[0033] Embodiment: A mounting structure for a rail transit control box includes a control box 1, wherein the control box 1 includes a shell 101, a cabinet door 102 and a dustproof ceiling 103, wherein the shell 101 is arranged outside the control box 1, the cabinet door 102 is hinged to the front of the shell 101, and the dustproof ceiling 103 is fixedly connected to the top of the shell 101.

[0034] A mounting structure 2 is provided inside the control box 1, and the mounting structure 2 includes a mounting plate 201, a nut column 202, a hexagonal bolt 203 and a buffer spring 204. The mounting plate 201 is provided inside the shell 101, the nut column 202 is fixedly connected to the inner back side of the shell 101, the hexagonal bolt 203 is threadedly connected to the front side of the nut column 202, and the buffer spring 204 is sleeved on the outside of the nut column 202. There are four groups of nut columns 202, hexagonal bolts 203 and buffer springs 204, which are respectively located at the four corners of the inner back side of the shell 101, and the two ends of the buffer spring 204 are respectively abutted between the inner wall of the shell 101 and the back side of the mounting plate 201 to provide buffer protection for the mounting plate 201.

[0035] A heat dissipation box 3 is fixedly connected to the bottom of the control box 1 . The heat dissipation box 3 includes a box body, a heat dissipation unit and an air exchange unit. An inspection door 302 is provided on the box body, and a handle 301 is provided on the inspection door 302 .

[0036] The heat dissipation unit is arranged inside the box body, and the heat dissipation unit includes a heat dissipation pipe 307 and a fin 308. The heat dissipation pipe 307 is fixedly connected to the top of the box body, and the fin 308 is fixedly connected to the outside of the heat dissipation pipe 307. There are multiple groups of heat dissipation pipes 307 and fins 308 and they are arrayed on the top of the box body, and both ends of each heat dissipation pipe 307 are connected to the bottom of the shell 101 to efficiently dissipate heat inside the shell 101. Since a heat dissipation base 3 is arranged at the bottom of the control box 1, the operating temperature inside the control box 1 can be effectively reduced while keeping the shell 101 sealed, thereby protecting the device, extending its service life, and ensuring safety.

[0037] The air exchange unit is arranged on the side of the box body, and includes a protective grille 305 and a fan A306. An air inlet 303 is provided on the left side of the box body, and an air outlet 304 is provided on the right side of the box body. The protective grille 305 is fixedly connected to the inner circle of the air outlet 304 of the box body, and the fan A306 is fixedly connected to the inner circle of the air outlet 304 of the box body. The fan A306 is powered on and rotates to blow the hot air in the heat dissipation box 3 out of the air outlet 304.

[0038] A heat sink 4 is provided at the bottom of the heat sink 3, a crossbeam 403 is provided inside the heat sink 4, the crossbeam 403 is connected to the inner side of the heat sink 4, two fans B401 are provided on the crossbeam 403, circuit lines are provided inside the crossbeam 403, each of which is connected to the two fans B401 for power supply, and a fan motor is provided on the crossbeam 403 to drive the fans B401 to rotate. A heat sink 404 is provided on the upper part of the heat sink 4, the heat sink 404 is connected to the base of the heat sink 3, and a plurality of ventilation holes 402 are provided on the side of the heat sink 4 for air circulation in the heat sink 4. The heat sink 4 is integrally connected and fixed to the heat sink 3.

[0039] A fixing buckle 5 is arranged on the bottom side of the control box 1 and the bottom side of the heat sink 3. The fixing buckle 5 is L-shaped. A protruding clamping block 503 and a concave hole 504 are arranged on the buckle shell 501 of the fixing buckle 5. The size of the protruding clamping block 503 matches the concave hole 504. A movable passage is arranged in the buckle shell 501. A notch is arranged on the L-shaped long column of the buckle shell 501. A rotating block 502 is arranged in the notch. Rotating shafts 507 are arranged at both ends of the rotating block 502. A shaft hole is correspondingly provided in the groove of the body 501, and the shaft 507 is arranged in the shaft hole. The rotating block 502 is semicircular in style. A paddle 506 is provided on the arc surface of the shaft block 502, and a spring 505 is provided on the paddle 506. One end of the spring 505 is arranged on the surface of the paddle 506, and the other end is arranged and fixed in the buckle shell 501. At the same time, a spring activity passage is provided in the buckle shell 501 for the extension and retraction activity of the spring 505, and the paddle 506 is partially arranged on the outside of the buckle shell 501 for activity. Under normal circumstances, the pull of the spring 505's own retraction force will move the paddle 506 toward the spring active path. At this time, the rotating block 502 is rotated to keep the rotating block 502 outside the groove of the buckle shell 501 on the partial arc surface. When in use, the two L-shaped long columns of the fixed buckles 5 are inserted into each other accordingly. During the mutual insertion process, the clamping blocks 503 on the two buckle shells 501 contact the rotating block 502. The force of the movement of the clamping blocks 503 drives the rotating block 502 to rotate. The horizontal surface of the rotating block 502 is parallel to the groove surface. The two fixed buckles 5 can be quickly buckled. At this time, because the rotation of the rotating block 502 also drives the paddle 506 to deflect, the deflection force of the paddle 506 is greater than the pulling force of the spring 505. Therefore, the spring 505 stretches and elongates. When the lever 506 is pushed to the limit position of the groove, it means that the horizontal planes of the two rotating blocks 502 are parallel to the planes of the buckle shell 501, and the two fixed buckles 5 can be disconnected.

[0040] In actual operation, when this device is used, in a rail transit station, the sound waves and vibrations caused by the operation of the vehicle will be reduced under the action of the buffer spring 204, thereby protecting the components installed on the mounting plate 201 and preventing the bolts from loosening due to vibration. When the control box 1 is running, the heat generated inside will be transferred through the heat pipe 307 and dissipated inside the base cabinet 301 through the fins 308. At the same time, the fan B401 in the heat dissipation base 4 rotates to blow the air upward into the heat dissipation box 3, and then driven by the fan 306, the hot air flows out from the air outlet 304, which can keep the internal sealing of the shell 101 and continue to dissipate heat. At the same time, the setting of the fixed buckle 5 can quickly connect and fix the control box 1 with the heat dissipation box 3, and can be quickly disassembled when not needed, realizing the process of rapid installation and disassembly.

[0041] A method suitable for rapid installation of a rail transit control box, using the following steps: Step A: Install the nut column 202 on the back of the housing 101 in the control box 1, sleeve the buffer spring 204 on the outside of the nut column 202, and thread the hexagonal bolt 203 through the mounting plate 201 and connect it to the front of the nut column 202; Step B: fix the heat dissipation base 4 in the desired installation position, align the front of the control box 1 with the front of the heat dissipation box 3, align the fixing buckle 5 on the control box 1 with the fixing buckle 5 on the heat dissipation box 3, and buckle them up and down; Step C: Install the required power supply equipment on the mounting plate 201 of the control box 1, and close and lock the cabinet door after the installation is completed; Step D: When the control box 1 needs to be disassembled, move the paddle 506 on the fixed buckle 5 to rotate the rotating block 502. The rotation of the rotating block 502 drives the rotating block 502 on the other side to rotate in the opposite direction. When the paddle 506 is moved to the groove limit part, it means that the horizontal planes of the two rotating blocks 502 are parallel to the surface of the buckle shell 501. The two fixed buckles 5 can be uncoupled, the control box 1 and the heat sink 3 can be disassembled separately, and the heat sink 3 can be recycled.
