Sweet potato cellar special-purpose ventilation duct

Abstract

A sweet potato cellar special-purpose ventilation duct relates to the sweet potato storage technical field, and comprises a pipe body, side pipes, and a control board; the pipe body is arranged on the ground, and provided with side pipes; the top of the pipe body is provided with a filter net; a liquid level sensor is arranged in the lower portion of the pipe body; the control board is arranged in the ground of a connection portion between the pipe body and the ground; a stop plate is arranged in the control board; the control board is provided with a power source and a controller; the stop plate is provided with a motor; the controller, the motor, the power source and the liquid level sensor are mutually connected through wires; the sweet potato cellar special-purpose ventilation duct is simple in structure, easy to operate, can effectively ventilate a sweet potato cellar, can effectively prevent rainwater from invading the sweet potato cellar in rainy weathers, thus ensuring air conditions in the sweet potato cellar, and simultaneously reducing anoxic dangers when people enter the cellar.

Description

[0001] 【Technical Field】 [0002] The invention relates to the technical field of sweet potato storage, in particular to a special ventilation pipe for sweet potato cellars. [0003] 【Background technique】 [0004] It is well known that in the cultivation of sweet potatoes, a large amount of sweet potatoes harvested must be stored reasonably to ensure that they are not easy to rot. At present, people will dig pits several meters deep on the ground and expand the pit-like storage around the bottom of the pit. The sweet potato harvested from the sweet potato cellar is then placed in the storage cellar for long-term preservation. However, the current sweet potato cellar has the problem of insufficient ventilation. The oxygen content in the air in the sweet potato cellar closed for a long time is very small, and people need to go down the cellar. When picking sweet potatoes, it is easy to produce hypoxia, which can endanger people’s lives in severe cases. At present, people just drill so...

Problems solved by technology

[0004] It is known that in sweet potato planting, a large amount of sweet potatoes harvested must be properly stored to ensure that it is not easy to rot. At present, people will dig a few meters deep cellar wells on the ground, and expand and dig out pit-like storage around the bottom of the cellar wells. Then put the harvested sweet potatoes in the storage cellar for long-term storage, but the current sweet potato cellar has the problem of insufficient ventilation. Oxygen deficiency is easy to occur when taking sweet potatoes, and it will endanger people's lives in serious cases. At present, people just make some simple ventilation holes vertically into the cellar well on the ground. These ventilation holes play a certain role in ventilation, but if it rains Weather, rainwater will flow into the cellar well along the ventilation holes, and the rainwater soaked in the sweet potatoes will spoil the sweet potatoes and affect the quality of sweet potato storage
