Description

Technical Field

[0001] The present application relates to the field of prefabricated warehouses, and in particular to a prefabricated warehouse with an automatic air supply and temperature control system. Background Art

[0002] Prefabricated cabins are a key embodiment of the new technologies, new materials, and new equipment used in smart distribution stations. They consist of a prefabricated cabin, primary equipment cabinets (distribution equipment, energy storage equipment, etc.), and cabin auxiliary facilities. They are manufactured, assembled, wired, and debugged in the factory and transported to the project site as a whole, where they are placed on the foundation for installation. Once the prefabricated cabin arrives on site, it only needs to be connected to the external wiring before it can be quickly put into operation. This not only effectively shortens the construction period and improves project efficiency, but also enhances project quality and stability. Existing prefabricated cabins use temperature measurement to control the start and stop of air conditioning, which is not conducive to energy conservation. Furthermore, they lack dedicated air supply channels with the equipment, resulting in low air conditioning utilization. Summary of the Invention

[0042] The following briefly describes the working process and usage of a prefabricated warehouse with an automatic air supply and temperature control system in the above embodiment:

[0043] When the temperature detected by internal temperature sensor 8 inside the cabinet exceeds the set value of external temperature sensor 6, the control module sends a signal to start motor 34 and exhaust fan 5. Motor 34 drives windshield 32 via transmission rack 33. When transmission rack 33 contacts micro-travel switch 35 on the rear side, motor 34 is de-energized and stops, and air outlet 3 opens. Cold air from outside the cabinet passes through air inlet hood 31 into a dedicated ventilation duct, entering the cabinet from the bottom and exiting from the top. This air removes heat from the cabinet and transfers it to the upper chamber. Exhaust fan 5 then exhausts the heat from the cabinet to the outside.

[0044] When the temperature sensor inside the power distribution equipment detects that the internal temperature of the power distribution equipment is higher than the set value, the control module sends a signal to the exhaust fan 5, motor 34, and inter-row air conditioner 4 (if the exhaust fan 5 is in the started state, its circuit is powered off and the exhaust fan stops working. If the exhaust fan 5 is in the stopped state, the state remains unchanged; if the air outlet 3 is in the open state, the motor 34 will start and close the air outlet 3. When the transmission rack 33 touches the micro-travel switch 35 at the front end, the motor 34 is powered off and stops moving. If the air outlet 3 is in the closed state, the motor 34 does not move). The cold air from the inter-row air conditioner 4 is blown into the ventilation duct. It enters the cabinet from the bottom of the power distribution equipment cabinet, meeting the requirement of lowering the temperature of the power distribution equipment. When the temperature inside the power distribution equipment cabinet drops to the set value, the temperature sensor inside the power distribution equipment cabinet sends a signal and the inter-row air conditioner stops working.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, rather than to limit them. Although the embodiments of the present application have been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
