[0002] The elevator control cabinet is the brain that controls the operation of the elevator. The elevator control cabinet is mostly installed next to the elevator shaft on the top floor or underground or in an additional reserved elevator control room to control the operation of the elevator.

[0003] The existing Chinese patent with publication number CN107010501B discloses an elevator control cabinet, which includes a frame, a mounting plate for mounting components, a circuit breaker mounted on the mounting plate, and an electromagnetic contactor. A soundproof wall containing sound-absorbing material is arranged around the electromagnetic contactor in all directions without the mounting plate to isolate the electromagnetic contactor from other components. The soundproof wall does not contact the mounting plate and is directly mounted on the frame.

[0004] The above patent can suppress the noise of the electromagnetic contactor and has a certain heat dissipation capacity, but it still has some disadvantages, such as: when controlling multiple elevators, its operating power is large, and due to the limitations of the installation environment of the elevator control cabinet, its heat dissipation capacity is limited, and it can be improved. Summary of the invention

[0005] In view of the problems mentioned in the background technology, an object of the present invention is to provide an elevator control cabinet with a heat dissipation structure to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: An elevator control cabinet with a heat dissipation structure comprises a cabinet body, a cabinet door is hinged on one side of the cabinet body, a bearing plate for integrating and fixing control elements is arranged in the cabinet body, the bearing plate is rotatably connected in the cabinet body, side heat dissipation openings are respectively provided on both sides of the cabinet body, a window blocking structure is provided at the side heat dissipation opening, a driving component for driving the bearing plate to flip and driving the window blocking structure to open the side heat dissipation opening is also provided in the cabinet body, an auxiliary heat dissipation small window is provided on the cabinet door, a small window shielding component for opening the auxiliary heat dissipation small window when overheating in the cabinet body is provided at the auxiliary heat dissipation small window, and a heat dissipation fan is provided in the cabinet body.

[0007] By adopting the above technical scheme, the elevator control cabinet with a heat dissipation structure has good heat dissipation capacity. When the temperature inside the elevator control cabinet is too high, the driving component can be used to drive the carrier plate to flip, and at the same time as the carrier plate flips, it can drive the window blocking structure at the side heat dissipation port to open, so that the control components on the carrier plate can be directly exposed to the side heat dissipation port, and the side heat dissipation port and the heat dissipation fan are used to assist in convection, thereby improving the heat dissipation capacity; and when the carrier plate is flipped to a certain angle, the small window shielding component can be triggered to open the auxiliary heat dissipation small window on the cabinet door, thereby further improving the heat dissipation capacity of the control cabinet; thereby achieving a good heat dissipation effect.

[0008] Preferably, the window blocking structure includes an upper slide rail, a lower slide rail, a side block door and a connecting rod, the upper slide rail and the lower slide rail are respectively fixed on the upper and lower sides of the side heat dissipation outlet, the side block door is slidably connected between the upper slide rail and the lower slide rail, and the connecting rod is connected and fixed between the two side block doors.

[0009] By adopting the above technical solution, the side heat dissipation outlet can be blocked by the side door. When the temperature inside the elevator control cabinet is not high, the side heat dissipation outlet can be closed by the side door. When the temperature inside the elevator control cabinet rises rapidly, the side door slidably connected between the upper slide rail and the lower slide rail can be opened by the drive assembly to dissipate side heat.

[0011] By adopting the above technical solution, when the first servo motor fixed on the bearing seat is started, it can drive the load-bearing plate to rotate in the cabinet. When the load-bearing plate rotates, the extended shaft and the linkage control assembly located at its end can drive the side door at the side heat dissipation outlet to open, thereby realizing linkage control.

When the second pulley rotates, the first pulley can be driven to rotate through the transmission of the belt, thereby driving the extension shaft to rotate. When the extension shaft rotates, it can drive the crank disk to rotate, thereby driving the first connecting rod to swing, and driving the second connecting rod to pull the side door to open; when the first servo motor drives the carrying plate to return to its position, it can drive the extended shaft to rotate again, thereby driving the linkage control component to close the side door.

[0014] Preferably, the small window covering assembly includes a window door, a sealing strip, a second servo motor, a controller, and an infrared sensor.

[0015] By adopting the above technical solution, when the carrier plate is flipped to a vertical position, the infrared sensor will irradiate the electrical components on the carrier plate. When it senses that the temperature is too high, it will feedback the high and low level changes to the controller, so that the controller can be used to start the second servo motor. When the second servo motor is started, it can drive the window door at the auxiliary heat dissipation window to flip open, thereby further improving the heat dissipation capacity.

[0016] Preferably, the bottoms of the two side heat dissipation openings are respectively arranged as inclined slopes, and the tops of the two side heat dissipation openings are respectively fixed with side guard top edges.
