Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide treatment technology for the bottom of cellars, and particularly relates to a portable carbon dioxide fan linkage device for the bottom of cellars. Background Technology

[0002] During the fermentation process in baijiu cellars, microorganisms convert the starch and sugars in the raw materials into alcohol and various flavor substances, while also producing a large amount of carbon dioxide gas (a metabolite of yeast). High concentrations of carbon dioxide are produced during the brewing fermentation process. If the concentration in a confined space (such as a fermentation tank or cellar) exceeds 5%, it can cause suffocation and death. The average concentration over 8 hours is ≤5000ppm. Because carbon dioxide is heavier than air, these gases will accumulate at the bottom of the cellar and cannot diffuse. If the carbon dioxide concentration is too high during the cleaning of the cellar, it can cause safety accidents and endanger lives.

[0003] The existing processing methods used by wineries have the following technical defects: Open-loop control: Wineries typically use fans to blow air into the fermentation pits for a fixed period before workers enter the pits. However, this cannot confirm whether the carbon dioxide concentration has truly dropped to a safe level, as the ventilation fans are not correlated with the carbon dioxide concentration at the bottom of the pits. It cannot be guaranteed that the carbon dioxide concentration will drop below the safe threshold after the fans start operating, which can easily lead to safety accidents. If the carbon dioxide concentration at the bottom of the pits remains high after the fans have been running for a period of time, workers entering the pits still face life-threatening risks.

[0004] Waste of manpower: In order to ensure operational safety, the winery has to adopt a two-person operation system, with one person working in the cellar and the other standing guard outside the cellar as a safety officer, which wastes manpower.

[0005] Inconvenient to operate: The ventilation fans need to be moved to the pits and AC 220V power needs to be brought to each pit and extended to the pits via a reel.

[0006] Low intelligence and unreliability: Existing security mechanisms mainly rely on the individual behavior of observers for protection. If observers lack a sense of responsibility and neglect their duties, security incidents can also occur.

[0007] Lack of alarm mechanism: When carbon dioxide levels rise during operation and exceed the threshold, there is a lack of audible and visual alarms to warn operators.

[0008] Therefore, in order to overcome the above technical defects, it is urgent to develop a safe and reliable device. Utility Model Content

[0009] The purpose of this utility model is to provide a portable carbon dioxide fan linkage device at the bottom of a cellar, so as to solve the technical problem that the carbon dioxide concentration at the bottom of the cellar cannot be known in real time in the existing technology, which is prone to causing safety accidents.

[0010] To solve the above-mentioned technical problems, this utility model provides a portable carbon dioxide fan linkage device for the bottom of a cellar, including a housing. The exterior of the housing is equipped with an air extraction component and a monitoring component for real-time monitoring of the carbon dioxide concentration at the bottom of the cellar. The interior of the housing is equipped with a power supply component, an inverter, and a control component. The housing is equipped with a main control module, which is electrically connected to the air extraction component, the monitoring component, the power supply component, and the control component. The main control module operates the air extraction component to start and stop working based on the carbon dioxide concentration value obtained by the monitoring component through the control component.

[0011] Preferably, the air extraction assembly includes a fan and a foldable fan duct.

[0012] Preferably, the monitoring components include a carbon dioxide sensor and a corrugated pipe.

[0013] Preferably, the power supply assembly includes a battery pack, a charger, and a power switch.

[0014] Preferably, the control component is a smart circuit breaker.

[0015] Preferably, the housing is also equipped with a battery power acquisition and display module for collecting and displaying battery power.

[0016] Preferably, the enclosure is further provided with a power conversion module to provide a stable DC power supply to the main control module.

[0017] Preferably, the main control module further includes a human-machine interface for setting and saving alarm thresholds.

[0018] Preferably, the enclosure is also equipped with an audible and visual alarm module, which is activated or deactivated by the main control module based on whether the carbon dioxide concentration value obtained by the monitoring component exceeds the alarm threshold.

[0019] Preferably, the housing is also equipped with a charging port, a pull rod, and wheels.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This invention integrates the entire device into the interior of a van, increasing ease of use. It uses a battery pack for power, converting DC to AC via an inverter, and then feeds the AC power to the source end of a circuit breaker. The fan acts as an actuator connected to the load end of the circuit breaker. The main control module handles parameter settings, circuit breaker start / stop control, battery power acquisition and display, and audible / visual alarm start / stop control. It also collects real-time carbon dioxide concentration data at the bottom of the pit and links the fan and audible / visual alarm based on this concentration. The fan features a foldable duct, allowing direct extraction of carbon dioxide gas from the bottom of the pit for higher efficiency. The technical advantages are further reflected in the following aspects: Real-time response: Real-time acquisition of carbon dioxide concentration values ​​at the bottom of the pit, and real-time control of the start and stop of the blower and alarm.

[0021] Closed-loop control is adopted: the carbon dioxide concentration value is linked to the blower. The blower operation is controlled according to the carbon dioxide concentration value. When the carbon dioxide concentration exceeds the safety threshold, the blower can actively discharge carbon dioxide gas from the bottom of the pit. When it falls below the safety threshold, the blower automatically stops operating.

[0022] Automatic alarm mechanism: This system prevents the risk of suffocation. During operation, the carbon dioxide concentration is monitored in real time. When the carbon dioxide concentration exceeds the safe threshold, an alarm is triggered proactively via voice and visual cues to alert the operator. Compared to manual observation, this method is safer and more reliable, eliminating the need for additional observers and saving labor costs.

[0023] Simple to operate: The fan, battery, power supply, carbon dioxide detection device, linkage device, etc. are integrated into a box-type trolley. The device can be used by pushing it to the corresponding cellar. There is no need to move the fan or introduce a 220V reel for power.

[0024] High safety factor: It adopts automatic ventilation and automatic alarm, which is safer and more reliable than human subjective judgment.

[0025] Better control: Because carbon dioxide is heavier than air, it decreases faster by pumping air than by blowing air. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1-4 As shown, this utility model provides a portable carbon dioxide fan linkage device for the bottom of a cellar, including a housing 14. The housing 14 is equipped with an air extraction component and a monitoring component for real-time monitoring of the carbon dioxide concentration at the bottom of the cellar. The housing 14 is equipped with a power supply component, an inverter 13 and a control component. The housing 14 is equipped with a main control module 1. The main control module 1 is electrically connected to the air extraction component, the monitoring component, the power supply component and the control component. The main control module 1 operates the air extraction component to start and stop working through the control component based on the carbon dioxide concentration value obtained by the monitoring component.

[0032] The main control module 1 also provides a human-machine interface for setting and saving the upper and lower thresholds of the linkage alarm. Clicking the touchscreen of the main control module allows for setting and saving the alarm thresholds. The human-machine interface can also display the real-time collected carbon dioxide concentration values.

[0033] In one specific embodiment provided in this application, the housing 14 is further provided with a battery power acquisition and display module 7 for acquiring and displaying battery power.

[0034] In one specific embodiment provided in this application, the housing 14 is further provided with a power conversion module 6, which is used to provide a stable DC power supply to the main control module 1. When the power supply voltage of the main control module does not match the battery output voltage, a power conversion module such as a step-down module is required.

[0035] In one specific embodiment provided in this application, the housing 14 is further provided with an audible and visual alarm module 9, which is used to provide light and voice alarms. The main control module 1 reads the carbon dioxide concentration value obtained by the monitoring component and determines whether it exceeds the alarm threshold, and controls the start and stop actions of the audible and visual alarm module 9.

[0036] In one specific embodiment provided in this application, the extraction assembly includes a fan 4 and a foldable fan duct. This device is placed on the ground above the pit and the foldable fan duct is led to the bottom of the pit. The fan and the foldable fan duct can extract carbon dioxide from the bottom of the pit.

[0037] Among them, fan 4 uses an AC fan, and the DC power is insufficient to meet the required power requirements. Therefore, inverter 13 is needed to convert DC power into AC220V AC power for use.

[0038] In one specific embodiment provided in this application, the monitoring component includes a carbon dioxide sensor 2 and a corrugated pipe. The carbon dioxide sensor 2 extends to the bottom of the pit via the corrugated pipe and is used to collect carbon dioxide concentration values; the corrugated pipe also serves to protect the communication line between the carbon dioxide sensor and the main control module 1.

[0039] In one specific embodiment provided in this application, the power supply assembly includes a battery pack 10, a charger 12, and a power switch 8. This device employs a rechargeable battery power supply mode, wherein the battery pack 10 provides power to the fan linkage device, the charger 12 charges the battery pack, and the power switch 8 is used to connect and disconnect the main power supply.

[0040] In one specific embodiment provided in this application, the control component is a smart circuit breaker 5, used to disconnect or connect the power supply to the ventilation fan.

[0041] In one specific embodiment provided in this application, the housing 14 is also provided with a charging port 11 for providing a charging interface for the fan linkage device.

[0042] In one specific embodiment provided in this application, the box 14 is further provided with a pull rod and wheels. This utility model integrates the entire device into a small van, which uses a stainless steel pull-rod box to provide a carrier for the linkage system, facilitating transportation.

[0043] Working principle: Connect the battery pack to the inverter, and the DC power is converted to 220V AC power for use. Connect the source end of the smart circuit breaker to the 220V AC power, and the load end of the smart circuit breaker to the fan. Send the carbon dioxide sensor to the bottom of the pit through a corrugated pipe to collect the carbon dioxide concentration value at the bottom of the pit in real time. Introduce the foldable fan duct to the bottom of the pit. The main control module reads the carbon dioxide value and battery power in real time and controls the display. When the carbon dioxide concentration exceeds the limit, the main control module controls the audible and visual alarm to sound and controls the smart circuit breaker to conduct, supplying power to the fan. The fan starts working and extracts the carbon dioxide from the bottom of the pit. When the carbon dioxide concentration drops below the safety threshold, the main control module controls the audible and visual alarm to de-alarm and controls the smart circuit breaker to open, and the fan stops operating.

[0044] This invention integrates the entire device into the interior of a van, increasing ease of use. It uses a battery pack for power, converting DC to AC via an inverter, and then feeds the AC power to the source end of a circuit breaker. The fan acts as an actuator connected to the load end of the circuit breaker. The main control module handles parameter settings, circuit breaker start / stop control, battery power acquisition and display, and audible / visual alarm start / stop control. It also collects real-time carbon dioxide concentration data at the bottom of the pit and links the fan and audible / visual alarm based on this concentration. The fan features a foldable duct, allowing direct extraction of carbon dioxide gas from the bottom of the pit for higher efficiency. The technical advantages are further reflected in the following aspects: Real-time response: Real-time acquisition of carbon dioxide concentration values ​​at the bottom of the pit, and real-time control of the start and stop of the blower and alarm.

[0045] Closed-loop control is adopted: the carbon dioxide concentration value is linked to the blower. The blower operation is controlled according to the carbon dioxide concentration value. When the carbon dioxide concentration exceeds the safety threshold, the blower can actively discharge carbon dioxide gas from the bottom of the pit. When it falls below the safety threshold, the blower automatically stops operating.

[0046] Automatic alarm mechanism: This system prevents the risk of suffocation. During operation, the carbon dioxide concentration is monitored in real time. When the carbon dioxide concentration exceeds the safe threshold, an alarm is triggered proactively via voice and visual cues to alert the operator. Compared to manual observation, this method is safer and more reliable, eliminating the need for additional observers and saving labor costs.

[0047] Simple to operate: The fan, battery, power supply, carbon dioxide detection device, linkage device, etc. are integrated into a box-type trolley. The device can be used by pushing it to the corresponding cellar. There is no need to move the fan or introduce a 220V reel for power.
