DETAILED DESCRIPTION

[0019] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0020] First Implementation Method Figure 1-Figure 9 The raw grain storage body 1 is shown to include a control panel 12 fixedly installed at the front end of the raw grain storage body 1 and an automatic adjustment processing unit mounted in the control panel 12. The front and rear inner walls of the raw grain storage body 1 are fixedly connected to a plurality of support bars, the inner ends of the support bars are fixedly connected to a thermal insulation layer 5, and a thermal insulation gap is formed between the raw grain storage body 1 and the thermal insulation layer 5. The input end of the automatic adjustment processing unit is connected to the temperature and humidity sensing unit, the temperature difference sensing unit and the grain parameter sensing unit, and the output end of the automatic adjustment processing unit is connected to the ventilation temperature control adjustment unit and the insulation adjustment unit; A plurality of internal temperature sensing components 4 are installed in the middle of the outer end of the raw grain storage body 1, and the inner end of the internal temperature sensing component 4 extends through the insulation gap to the inner side of the insulation layer 5, and a temperature difference sensing component 7 is also arranged in the internal temperature sensing component 4; The input end of the temperature and humidity sensing unit is connected to the internal temperature sensing component 4 by signal, the input end of the temperature difference sensing unit is connected to the temperature difference sensing component 7 by signal, the input end of the grain parameter sensing unit is connected to the input end signal on the control panel 12, and the output ends of the ventilation temperature control adjustment unit and the insulation adjustment unit are both connected to the ventilation fan unit signal arranged on the rear side of the raw grain storage body 1. Through the cooperation of the internal temperature sensing component 4, the insulation layer 5, the temperature difference sensing component 7 and each unit, on the one hand, the inside and outside of the warehouse of the raw grain storage body 1 can be isolated, effectively avoiding the external temperature from directly acting on the warehouse of the raw grain storage body 1, and avoiding the formation of the inner wall of the raw grain storage body 1. On the other hand, it can also control the temperature in the insulation gap formed between the raw grain storage body 1 and the insulation layer 5, thereby further reducing the impact of external temperature changes on the raw grain storage body 1 in the warehouse, and play an effective role in heat preservation and isolation. While fully ensuring the storage temperature in the raw grain storage body 1, it also reduces the rate of influence of external temperature changes, thereby effectively ensuring the storage quality of the raw grain storage body 1, avoiding the problem of mildew of the grain in the warehouse, extending the storage time of the grain and ensuring the quality of the grain.

[0021] Figure 3-Figure 8 It is shown that the internal temperature sensing component 4 includes an outer layer block 41 embedded in the raw grain storage body 1 and a temperature sensing block 42 embedded in 5, and the outer layer block 41 and the temperature sensing block 42 are arranged correspondingly, and the inner end of the temperature sensing block 42 is fixedly connected with a temperature and humidity sensing probe 421 extending into the insulation layer 5, and the input end of the temperature difference sensing unit is connected to the temperature and humidity sensing probe 421 signal. The setting of the temperature and humidity sensing probe 421 can monitor the temperature and humidity data of the grain in the warehouse of the raw grain storage body 1 in real time, and then can effectively assist the automatic adjustment processing unit to control the ventilation and temperature control adjustment unit to ensure the temperature and humidity in the warehouse of the raw grain storage body 1, thereby ensuring the storage quality and storage period of the grain, and can also respond and process in time when the temperature and humidity data in the warehouse are abnormal, thereby improving the automation degree and emergency response efficiency of the raw grain storage body 1.

[0022] Figure 3-Figure 8 The temperature difference sensing assembly 7 is shown to include a pressure insert 75 embedded in the outer end of the temperature sensing insert 42, a sliding channel 411 is provided in the outer insert 41, an I-shaped connecting block 72 is slidably connected in the sliding channel 411, a temperature conducting sealing block 412 extending to the outside of the raw grain storage body 1 is fixedly connected to the outer end of the outer insert 41, and a temperature sensing deformation strip 71 is fixedly connected between the temperature conducting sealing block 412 and the I-shaped connecting block 72; The inner end of the outer layer block 41 is fixedly connected with a thermal insulation elastic sleeve 73 connected to the sliding channel 411, and the inner end of the I-shaped connecting block 72 is fixedly connected to the thermal insulation elastic sleeve 73, the inner end of the thermal insulation elastic sleeve 73 is fixedly connected with a pressure bag 74, the inner end of the pressure bag 74 is fixedly connected to a pressure block 75, and the pressure bag 74 is connected to the pressure block 75, and a pressure probe 76 is fixedly connected to the pressure block 75, and the input end of the temperature difference sensing unit is connected to the pressure probe 76 signal. The cooperation of the temperature sensing deformation strip 71, the I-shaped connecting block 72, the thermal insulation elastic sleeve 73, the pressure bag 74 and the pressure probe 76 can not only sense the external ambient temperature, but also directly generate corresponding deformation through external temperature changes, so that the automatic adjustment processing unit can directly obtain the data generated by the temperature difference. While improving the temperature difference sensing efficiency and processing, it can also reduce the difficulty of data calculation and processing by the automatic adjustment processing unit, thereby reducing the burden of system operation and construction cost, and effectively promoting the economic benefits of the application of the raw grain storage body 1.

[0023] Figure 3-Figure 8 It is shown that the temperature-sensitive deformation strip 71 is made of a composite of multi-segment temperature-changing memory metal wires. When the temperature-sensitive deformation strip 71 is not deformed, the pressure bag 74 is in a semi-contracted state, and the stiffness coefficient of the thermal insulation elastic sleeve 73 is greater than the stiffness coefficient of the pressure bag 74, so that the pressure bag 74 can be kept semi-compressed. The temperature in the warehouse of the raw grain storage body 1 is controlled at 15°C-25°C, which can effectively store wheat, corn, rice and other grains. Then, the temperature-sensitive deformation strip 71 is selected to be in a normal state at a temperature of 15°C-25°C, and a contraction deformation occurs when the temperature it senses is lower than 12°C, and an elongation deformation occurs when the temperature it senses is higher than 28°C. Therefore, a deformation-triggered reaction can be generated in time when the external temperature changes, so that the automatic adjustment processing unit can timely control the temperature of the thermal insulation gap formed between the raw grain storage body 1 and the thermal insulation layer 5, so as to avoid the external temperature from affecting the temperature of the grain in the warehouse of the raw grain storage body 1. While effectively avoiding the probability of condensation on the grain, the stability of the temperature in the warehouse of the raw grain storage body 1 is also effectively guaranteed.

[0024] Figure 1 and Fig. 9It is shown that a feed hopper 11 connected to the thermal insulation layer 5 is fixedly connected to the upper end of the raw grain storage body 1, and a thermal insulation air port 2 located on the left side of the feed hopper 11 and a thermal insulation circulation port 21 located on the right side of the feed hopper 11 are fixedly installed on the upper end of the raw grain storage body 1, and the thermal insulation air port 2 and the thermal insulation circulation port 21 are both connected to the thermal insulation gap, and the other ends of the thermal insulation air port 2 and the thermal insulation circulation port 21 are connected to the ventilation fan unit through an extended pipeline. The setting of the thermal insulation air port 2 and the thermal insulation circulation port 21 can effectively form a gap between the raw grain storage body 1 and the thermal insulation layer 5. The insulation gap is used for temperature control circulation, and effective insulation is achieved by introducing transitional circulating air into the insulation gap, which plays an effective role in temperature exchange and temperature control, effectively avoiding the influence of external temperature changes on the temperature inside the warehouse of the raw grain storage body 1, avoiding the problem of grain condensation, and thus improving the storage quality of the raw grain storage body 1, and can also maintain the inner wall temperature of the raw grain storage body 1 through insulation circulation, reducing the problem of condensation, and further ensuring the storage quality of the raw grain storage body 1.

[0025] Figure 2 and Fig. 9 It is shown that the output end of the automatic adjustment processing unit is also connected to the ventilation temperature control unit, and the outer end of the insulation air outlet 2 is also provided with an electric heating sleeve and a temperature measuring probe. The output end of the ventilation temperature control unit is connected to the electric heating sleeve signal, and the input end of the ventilation temperature control unit is also connected to the temperature measuring probe signal. The arrangement of the ventilation temperature control unit, the electric heating sleeve and the temperature measuring probe can transport higher temperature air to the insulation gap when the outside temperature is low. The maximum value of this higher temperature cannot exceed the upper limit temperature of grain storage of 25°C, which can effectively maintain the temperature in the warehouse.

[0026] Figure 1 and Fig. 9 It is shown that a ventilation and temperature control air outlet 3 connected to the thermal insulation layer 5 is fixedly connected to the upper left end of the raw grain storage body 1, and a plurality of ventilation circulation outlets 31 connected to the thermal insulation layer 5 are fixedly connected to the middle and lower right end of the raw grain storage body 1, and the plurality of ventilation circulation outlets 31 are evenly distributed in the vertical direction, the input end of the ventilation and temperature control air outlet 3 is connected to the ventilation fan unit, the output end of the ventilation circulation outlet 31 is connected to the ventilation fan unit, and the plurality of ventilation circulation outlets 31 are independently controlled. The setting of the plurality of ventilation circulation outlets 31 can promote the effect and uniformity of regulating the temperature inside the warehouse of the raw grain storage body 1, thereby improving the ventilation volume and ventilation efficiency inside the grain, effectively avoiding the problem of poor heat dissipation inside the grain, and thus effectively ensuring the storage quality of the grain.

[0027] It should be noted that the ventilation fan unit is a prior art and may include a blower unit, an air dryer, an air filter, a plurality of connecting pipes and control valves respectively installed on the connecting pipes. The input end of the blower unit is connected to the air dryer and the air filter, and the output end of the blower unit is respectively connected to the extension pipe on the insulation air outlet 2 and the ventilation temperature control air outlet 3 through the connecting pipe, and the extension pipe on the insulation circulation port 21 and the ventilation circulation port 31 are both connected to the air dryer or the pipe air filter through the connecting pipe, so as to form a ventilation circulation control and be able to regulate the circulation efficiency. The ventilation fan unit here is only for reference. The specific setting method can be selected and added by technicians in this field according to actual needs. The fan parameters are set: when the volume of the raw grain storage body 1 is set to 40m³, its output is small The wheat capacity does not exceed 30T, the storage rice flux does not exceed 23T, and when wheat is stored in the raw grain storage body 1, the air volume of the blower group is selected to be 5000m³ / h-9000m³ / h, and the wind pressure of the blower group is 1350Pa-2890Pa, and the power of the blower group is 11kw; when rice is stored in the raw grain storage body 1, the air volume of the blower group is selected to be 4000m³ / h-7000m³ / h, and the wind pressure of the blower group is 1050Pa-2200Pa, and the power of the blower group is 11kw; when corn is stored in the raw grain storage body 1, the air volume of the blower group is selected to be 4800m³ / h-8500m³ / h, and the wind pressure of the blower group is 750Pa-1550Pa, and the power of the blower group is 11kw. Relevant parameters can be adjusted according to actual usage conditions.

[0028] Figure 1-Figure 9 It is shown that after grain is stored in the raw grain storage body 1, the relevant technicians control the storage parameters of the internal warehouse of the raw grain storage body 1 according to the grain variety and local environmental settings, and input the parameters such as the stored grain variety, storage temperature, storage humidity and temperature and humidity floating standard to the grain parameter sensing unit through the input end of the control panel 12, and then the grain parameter sensing unit transmits these parameters to the automatic adjustment processing unit; When the grain is just put into the warehouse, the automatic adjustment processing unit can judge the basic temperature and humidity of the grain through the grain temperature and humidity data transmitted to the temperature and humidity sensing unit by the temperature and humidity sensing probe 421, and then send the ventilation and temperature control quality to the ventilation and temperature control adjustment unit to dehumidify and cool the grain in advance. Then, after the temperature and humidity of the grain reach the standard stability, the automatic adjustment processing unit controls the ventilation and temperature control adjustment unit to perform energy-saving ventilation and temperature control mode, thereby solving energy consumption while ensuring the grain storage environment and improving the environmental protection of the raw grain storage body 1; In the subsequent continuous use of the raw grain storage body 1, if the external temperature is within the standard range of the grain storage temperature, the temperature-sensitive deformation strip 71 will not be deformed, and the pressure probe 76 transmits the balanced temperature data to the temperature difference sensing unit, so that the automatic adjustment processing unit can directly judge the external temperature data. At the same time, the temperature and humidity sensing probe 421 transmits the temperature and humidity data of the grain to the automatic adjustment unit through the temperature and humidity sensing unit, and the automatic adjustment processing unit sends an energy-saving temperature control instruction to the ventilation and temperature control unit, so as to achieve good temperature control and energy-saving and environmental protection effects; If the outside temperature is lower than the standard range of the grain storage temperature and reaches the low-temperature deformation temperature of the temperature-sensitive deformation strip 71, the temperature-sensitive deformation strip 71 will contract, thereby driving the I-shaped connecting block 72 to move toward the outside of the raw grain storage body 1 in the sliding channel 411, and the contraction of the temperature-insulating elastic sleeve 73 drives the pressure bag 74 to stretch and deform, thereby releasing the space of the pressure bag 74, reducing its internal pressure, and making the pressure probe 76 sense the pressure reduction. Then, the pressure probe 76 transmits the data of the pressure reduction to the temperature difference sensing unit, and the temperature difference sensing unit feeds back the data of the low temperature outside. To the automatic adjustment processing unit, after receiving the low-temperature temperature difference data, the automatic adjustment processing unit sends a control instruction to the insulation adjustment unit, and sends an instruction to the ventilation temperature control unit, using the electric heating sleeve to heat the air in the insulation air outlet 2, and sends temperature data to the ventilation temperature control unit through the temperature sensing of the temperature measuring probe, so as to avoid the influence of the insulation temperature on the grain temperature caused by the excessively high insulation temperature, and also avoid the problem of condensation on the grain. The insulation adjustment unit starts the pipe valve of the ventilation fan unit to supply air to the insulation air outlet 2, so that air with a certain amount of heat enters the original The heat is discharged from the insulation gap between the grain storage body 1 and the insulation layer 5 through the insulation circulation port 21. The insulation circulation method is used to prevent the external low temperature from being transmitted to the warehouse of the raw grain storage body 1, and reduce the problem of condensation on the inner wall of the raw grain storage body 1. Then, due to the insulation circulation effect of the insulation gap, the raw grain storage body 1 will have a certain temperature increase effect, so that the environment near the outside of the raw grain storage body 1 has a certain temperature increase effect. At the same time, it will act on the temperature-sensitive deformation strip 71 through the heat-conducting sealing block 412, and the automatic adjustment processing unit will continuously adjust the data of the temperature difference sensing unit. The temperature state caused by the external temperature is judged by reading continuously, and when the temperature-sensing deformation strip 71 keeps shrinking continuously, it is judged that the external temperature is low at this time, and the temperature caused is high, and then the temperature-insulating adjustment unit continuously produces the temperature-insulating circulation effect. After the temperature-sensing deformation strip 71 produces the recovery deformation, the automatic adjustment processing unit judges that the temperature difference between the external temperature and the temperature in the warehouse is small at this time, and sends a periodic action instruction to the temperature-insulating adjustment unit and the ventilation temperature control unit, so as to ensure the temperature-insulating effect while saving energy, thereby improving the storage quality of the raw grain storage body 1 and reducing the pathological effect of the grain; If the outside temperature is higher than the standard range of grain temperature and reaches the high temperature deformation temperature of the temperature-sensitive deformation strip 71, the temperature-sensitive deformation strip 71 will stretch, thereby driving the I-shaped connecting block 72 to move toward the inside of the raw grain storage body 1 in the sliding channel 411, and the elongation of the temperature-insulating elastic sleeve 73 drives the pressure bag 74 to produce compression deformation, thereby reducing the space of the pressure bag 74, increasing its internal pressure, and causing the pressure probe 76 to sense the increase in pressure, and then the pressure probe 76 transmits the data of the increased pressure to the temperature difference sensing unit, and the temperature difference sensing The unit feeds back the external high temperature data to the automatic adjustment processing unit. After receiving the high temperature difference data, the automatic adjustment processing unit sends a control instruction to the insulation adjustment unit. The insulation adjustment unit starts the pipe valve of the ventilation fan unit to supply air to the insulation air outlet 2, so that the air enters the insulation gap between the raw grain storage body 1 and the insulation layer 5, and then is discharged through the insulation circulation port 21. The external high temperature is prevented from being transmitted to the warehouse of the raw grain storage body 1 through the insulation circulation method, and the condensation problem on the inner wall of the raw grain storage body 1 and the grain is reduced. Later, due to the insulation circulation effect of the insulation gap, the raw grain storage body 1 will have a certain cooling effect, so that the environment near the outside of the raw grain storage body 1 has a certain cooling effect, and at the same time, it will act on the temperature-sensitive deformation strip 71 through the heat-conducting sealing block 412, and the automatic adjustment processing unit will continuously read the data of the temperature difference sensing unit to judge the temperature state caused by the external temperature. When the temperature-sensitive deformation strip 71 maintains continuous extension, it is judged that the external temperature is high at this time, and the temperature caused is large, and then the insulation adjustment unit continues to produce insulation circulation effect, and the automatic adjustment processing unit sends an instruction to the ventilation and temperature control adjustment unit to enhance ventilation, so as to reduce the impact of the external high temperature on the grain temperature, ensure the stability of the grain storage environment, and thus improve the storage quality of the grain. After the temperature-sensitive deformation strip 71 produces a recovery deformation, the automatic adjustment processing unit judges that the temperature difference between the external temperature and the temperature in the warehouse is small at this time, and sends a periodic action instruction to the insulation adjustment unit, while saving energy, ensuring the insulation effect, thereby improving the storage quality of the raw grain storage body 1 and reducing the pathological effect of the grain.

[0029] Second implementation method Figure 1-Figure 9It is shown that the input end of the automatic adjustment processing unit is also connected to a gap humidity sensing unit, and the lower end of the raw grain storage body 1 is fixedly connected to a liquid outlet 6 connected to the insulation gap, and a humidity measuring probe is arranged in the liquid outlet 6. The input end of the gap humidity sensing unit is connected to the humidity measuring probe signal. The setting of the gap humidity sensing unit and the humidity measuring probe can effectively detect the humidity data in the insulation gap, that is, to assist the automatic adjustment processing unit in judging the condensation condition of the inner wall of the raw grain storage body 1, so that it can effectively control the ventilation temperature of the insulation adjustment unit, while ensuring the insulation circulation effect, effectively reducing the problem of condensation on the inner wall of the raw grain storage body 1, thereby further ensuring the storage effect of the raw grain storage body 1.

[0030] Figure 2 and Fig. 9 It is shown that the output end of the automatic adjustment processing unit is also connected to an alarm unit and a remote transmission unit. The output end of the alarm unit is connected to the alarm signal arranged at the upper end of the control panel 12, and the output end of the remote transmission unit is connected to the wireless signal transmitter signal arranged in the control panel 12. The setting of the alarm unit and the remote transmission unit can promote the monitoring and adjustment of the raw grain storage body 1, reduce the maintenance difficulty of technicians, improve maintenance efficiency, and promote the efficiency of emergency effects.

[0031] Figure 1-Figure 9 It is shown that in the process of the automatic adjustment processing unit performing ventilation and temperature control on the inner bin of the raw grain storage body 1 and performing insulation control on the insulation gap, the test probe in the liquid outlet 6 will transmit the data in the insulation gap to the gap humidity sensing unit, and then transmit it to the automatic adjustment processing unit after conversion, so that the automatic adjustment processing unit can timely discover the problem of condensation on the inner wall of the raw grain storage body 1, and issue control instructions to the insulation adjustment unit and the ventilation temperature control unit according to the humidity data of the insulation gap, and promote the dissipation of humidity on the inner wall of the raw grain storage body 1 through insulation circulation, so as to ensure the dryness of the raw grain storage body 1. If the humidity data transmitted by the gap temperature sensing unit to the automatic adjustment processing unit continues to increase during the continuous action, the automatic adjustment processing unit sends a signal to the alarm unit and the remote transmission unit, so that the alarm unit starts the alarm and sends an audio-visual alarm signal to the relevant technical personnel, and then transmits the data to the mobile terminal through the wireless signal transmitter, so as to improve the emergency efficiency, timely inspect and maintain the raw grain storage body 1, and reduce the failure loss rate.

[0032] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
