Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary mechanism for a granary, in particular to an improvement of a granary ventilation opening isolation device. Background Art
[0002] The temperature inside the grain silo affects the temperature of the stored grain. In order to maintain a low temperature inside the silo, in addition to the silo roof and the walls around the silo, doors, windows and vents are also set. Granary vents are usually set on the sunny side, about 20CM from the ground. In practical applications, the temperature inside the silo should not be too high; ventilation in winter can reduce the temperature inside the silo, but in summer when the outside temperature is high, the outside temperature can be transmitted to the silo through the vents. In order to reduce the temperature conduction of the vents, the existing method is to use woven bags filled with fillers to block the vents to shield and reduce temperature conduction, but these fillers are not effective and will take up a large space when removed for storage and transportation. In addition, because the vents are too close to the ground, rainwater can easily enter the silo when it rains heavily. At the same time, the vents also need to be protected from insects and rats.
[0003] In reality, at this stage, except for the vents, which lack effective thermal insulation measures, other facilities that affect warehouse temperature have been basically solved; however, there is no better solution for the thermal insulation of the vents. Utility Model Content
[0004] The purpose of the utility model is to provide a heat-insulating air bag for the vent of a granary in view of the defects and shortcomings of the prior art, which can effectively isolate the temperature conduction inside and outside the granary, maintain the low temperature in the granary in summer, and prevent excessive moisture and rodents and insects from entering the granary, and has certain waterproof and insect-proof capabilities; at the same time, when these insulation devices are removed and not in use, the required storage space can be greatly reduced, which is convenient for the storage and transportation of the insulation devices.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes an airbag body 1, an airbag air inlet and outlet 2, a hose 3, a valve 4, and a flushing and deflation air interface 5. The airbag body 1 is a soft airbag, the airbag air inlet and outlet 2 is arranged at the bottom of the airbag body 1 and inserted into the airbag body 1, the lower part of the airbag air inlet and outlet 2 is sleeved with the hose 3, the lower part of the hose 3 is sleeved on the flushing and deflation air interface 5, and the middle part of the flushing and deflation air interface 5 is provided with a valve 4.
[0006] The airbag inlet and outlet 2 includes a plug-in tube 21, a locking nut 22, and a gasket 23. The plug-in tube 21 is a hollow T-shaped structure. The plug-in tube 21 passes through the outer wall of the airbag body 1 and is locked and fixed by the gasket 23 and the locking nut 22. The lower part of the plug-in tube 21 is sleeved with a hose 3. The T-shaped plug-in tube, the locking nut and the gasket can make the connection between the hose 3 and the airbag body 1 stable and not easy to leak.
[0007] A pressure gauge 6 is provided in the middle of the flushing and deflation gas interface 5, and the pressure gauge 6 is connected to the middle of the flushing and deflation gas interface 5 through a pipeline and is provided in parallel with the valve 4. The pressure gauge 6 is added so that the pressure value in the airbag body 1 can be intuitively displayed on the pressure gauge 6, so that the user can understand the pressure situation in the airbag at any time, and replenish the gas in the airbag according to the situation, thereby ensuring the functions of the airbag in heat insulation, insect and rodent prevention, and waterproofing.
[0008] The end of the flushing and deflation gas interface 5 away from the hose 3 is provided with a flushing and deflation gas nozzle 51. The inflation and deflation gas nozzle 51 is used to connect an inflation pump or to discharge the gas in the airbag body 1.
[0009] The upper and lower sleeve ends of the hose 3 are both provided with locking buckles 31, and the locking buckles 31 include locking pieces 311 and locking bolts 312. The hose 3 can be locked on the airbag air inlet and outlet 2 and the flushing and deflation air interface 5 by the locking bolts 312 and the locking pieces 311.
[0010] The two sides of the airbag body 1 are provided with auxiliary pulling mechanisms 11, which include a fixing sheet 111 and an auxiliary pulling rope 112. The auxiliary pulling rope 112 is fixed to the outer side of the airbag body 1 through the fixing sheet 111. The auxiliary pulling mechanism 11 can be provided to facilitate the quick and convenient pulling out of the airbag body 1 by pulling the auxiliary pulling rope 112 when taking out the airbag body 1, which is convenient for the user to operate.
[0011] The cross-sectional shape of the airbag body 1 is circular, square or other polygonal. The shape of the airbag body 1 can correspond to the cross-sectional shape of the granary vent, or a round airbag body made of a softer material can be used, and the round airbag is deformed to fill the entire vent by inflating the airbag.
[0012] The airbag body 1 is made of PVC plastic or rubber airbag with a thickness of 6 mm. According to the different application scenarios of the granary, airbag bodies of different materials can be selected.
[0013] The working principle of the utility model is as follows: when in use, the airbag body 1 is inflated through the flushing and deflation interface 5, or the airbag body 1 is placed in the vent before inflating, which can ensure that the airbag is full and close to the vent. The airbag body 1 after inflating is inflated with air, which is a poor conductor of heat, and plays a role in isolating the influence of the external temperature and maintaining the low temperature state in the warehouse; the airbag body 1 is close to the inner wall of the vent due to the strong gas pressure, preventing the external moisture and pests from entering the warehouse, and has waterproof and insect-proof functions. When the inflation is completed, the valve 4 can be locked to complete the sealing. At this time, although the flushing and deflation interface 5 is in an open state, there is no gas in and out; when the airbag is used as a whole and needs to be taken out, it only needs to open the valve 4 to discharge the gas in the airbag body 1. The cross-sectional shape and material selection of the airbag can be selected according to the application requirements. If the airbag with a softer material is selected, a circular airbag can be directly selected, because the vents of different shapes can be filled with the corners of the vents by the way of inflation deformation of the airbag, so that the airbag is close to the inner wall of the vent.
[0014] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: it can effectively isolate the temperature conduction inside and outside the granary, maintain the low temperature inside the granary in summer, and prevent excessive water vapor and rodents and insects from entering the granary, and has certain waterproof and insect-proof capabilities; at the same time, when these insulation devices are removed and not in use, the required storage space can be greatly reduced, which is convenient for the storage and transportation of the insulation devices.

The cross-sectional shape of the airbag body 1 is circular; the airbag body 1 uses a rubber airbag with a thickness of 6mm.
[0021] When this specific embodiment is used, the airbag body 1 is inflated through the flushing and deflation interface 5, and the airbag body 1 can also be placed in the vent before inflating, which can ensure that the airbag is full and close to the vent. The airbag body 1 after inflating is inflated with air, which is a poor conductor of heat, and plays a role in isolating the influence of the external temperature and maintaining the low temperature state in the warehouse; the airbag body 1 is close to the inner wall of the vent due to the strong gas pressure, preventing external moisture and pests from entering the warehouse, and has waterproof and insect-proof functions.
