Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional hierarchical intelligent grain warehouses, and specifically relates to a three-dimensional hierarchical intelligent storage warehouse for grain and cereals. Background Technique

[0002] In the grain industry, the grain storage link is crucial, which is directly related to the quality, safety and supply stability of grain. Grain warehouses can be divided into types such as receiving warehouses, transit warehouses, reserve warehouses, etc. according to different functions and scales. They play a key role in the production, circulation and reserve links of grain and are important infrastructure for ensuring national grain security.

[0003] With the steady growth of grain production and the increasing requirements for grain quality, the traditional storage mode is increasingly difficult to meet the needs. During the storage process of grain, it is extremely vulnerable to the influence of temperature and humidity changes, resulting in quality problems such as mildew and germination. At the same time, the rampant pests will also cause a large amount of grain loss. Moreover, traditional storage relies on a large number of manual workers for tasks such as grain condition monitoring and warehousing and outbound management, which not only has low efficiency but also is prone to human errors.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Through the collaborative work of the transport vehicle mechanism, palletizing machine mechanism, and three-dimensional layered rack mechanism in the intelligent warehouse, the present invention achieves efficient storage. The transport vehicle mechanism quickly transports the storage mechanism to the designated position, and the palletizing machine mechanism accurately places the storage mechanism at the corresponding position of the three-dimensional layered rack mechanism, making full use of space and enhancing the storage capacity. At the same time, this layout facilitates the classified storage and management of goods, improves the efficiency of warehousing operations, reduces the time for searching and handling goods, makes the entire storage process more efficient and orderly, reduces operating costs, and meets the large-scale grain storage requirements.

[0019] 2. Through the mutual cooperation of the bottom tray, baffle, enclosure, and sealing mechanism of the storage mechanism, the present invention achieves good sealing and gas exchange effects. The bottom tray and the sealing plate form a closed space, and the ventilation holes on the baffle and the enclosure do not contact each other and are staggered when sealed, ensuring the sealing performance. The air valve detection component monitors the temperature and humidity in real time, and through the five-way electric control valve and the conduit, in cooperation with the air conditioning component, vacuum adjustment component, etc., realizes the precise control of the gas in the storage environment, can timely discharge condensation, adjust the air humidity, create a stable storage environment, effectively prevent grain mildew and pests, ensure the quality of grain, and extend the grain storage period.

[0020] 3. Through the air conditioning component, vacuum adjustment component, insecticidal gas adjustment component, and nitrogen adjustment component in the gas control mechanism, combined with the five-way electric control valve, the present invention achieves all-round grain protection. The vacuum adjustment component evacuates to kill pests, the air conditioning component purifies the air and adjusts the humidity, the insecticidal gas adjustment component precisely eliminates pests, and the nitrogen adjustment component fills nitrogen to inhibit the respiration of grain and reduce the consumption of dry matter. These components work together, not only effectively preventing pests, but also delaying the aging of grain, maintaining the quality and nutritional value of grain, and enhancing the safety and stability of grain storage.

[0021] 4. Through the adaptive switching mechanism at the bottom of the sealing plate and in cooperation with other devices, the present invention achieves fire emergency protection. When a fire occurs inside the intelligent warehouse and causes signal transmission interruption, the adaptive switching mechanism is activated. The liquid in the liquid storage frame expands due to heat, pushing the switching block, so that nitrogen is ejected from the high-pressure nozzle through a specific channel. On the one hand, it prevents the fire from burning near the storage mechanism, and on the other hand, it inhibits the spread of the fire inside the warehouse. At the same time, the nitrogen generating equipment continues to work to ensure the nitrogen supply. This mechanism provides a reliable safety guarantee for grain storage, reduces the risk of damage to grain caused by fire, and ensures the safety of grain storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 11 , the present invention provides a technical solution for a three-dimensional layered intelligent storage warehouse for grain and cereals:

[0041] A three-dimensional layered intelligent storage warehouse for grain and cereals includes an intelligent warehouse 1;

[0042] In the intelligent warehouse 1, a transport vehicle mechanism 2 for transporting goods is provided. In the intelligent warehouse 1, a three-dimensional layered rack mechanism 3 for three-dimensional storage of goods is also provided. In the intelligent warehouse 1, a palletizing machine mechanism 4 for placing goods at designated positions in the three-dimensional layered rack mechanism 3 is also provided.

[0043] In the three-dimensional layered rack mechanism 3, a storage mechanism 5 for storing bulk grain is placed. The storage mechanism 5 includes a bottom tray 51. A baffle 52 with ventilation holes is fixedly connected to the outside of the bottom tray 51. A fence 54 with ventilation holes is slidably inserted into the inside of the baffle 52. A connecting column 56 is arranged at the middle position inside the bottom tray 51. Four groups of cross partitions 57 are arranged on the outside of the connecting column 56. The connecting column 56 is communicated with the cross partitions 57. An electric control component 510 is installed inside the connecting column 56. Multiple groups of gas valve detection components 58 for performing gas exchange are arranged on the outside of the cross partitions 57;

[0044] Above the storage mechanism 5, a sealing mechanism 6 is provided, and the sealing mechanism 6 is adsorbed on the top wall at the corresponding position in the three-dimensional layered rack mechanism 3 through an electromagnet;

[0045] On the sealing mechanism 6, a gas control mechanism 7 for switching the types of gases introduced is provided. The gas control mechanism 7 includes an air conditioning component 73, a vacuum adjustment component 74, an insecticidal gas adjustment component 75, a nitrogen adjustment component 76, and a five-way electric control valve 77. The outlet hole of the five-way electric control valve 77 is fixedly connected to a conduit 78, and the conduit 78 is inserted into the connecting column 56;

[0046] First, the storage mechanism 5 is transported to the designated position for loading grain by the transport vehicle mechanism 2. Subsequently, a quantitative amount of bulk grain is loaded into the storage mechanism 5 by the feeding vehicle. The bulk grain of a specified mass means that the height of the grain loaded into the storage mechanism 5 is slightly lower than the highest point of the baffle 52 after being leveled. The return spring 55 will push the movable part on the telescopic rod 53 to drive the enclosure 54 to move up to the highest point, thereby ensuring that the grain will not overflow from the periphery of the baffle 52 when the storage mechanism 5 is loading grain. After the loading is completed, the grain in the storage mechanism 5 is leveled. Subsequently, the storage mechanism 5 loaded with grain is transported to the palletizing machine mechanism 4 by the transport vehicle mechanism 2. The palletizing machine mechanism 4 moves and places the storage mechanism 5 loaded with grain to the corresponding position on the three-dimensional layered rack mechanism 3.

[0047] As an embodiment of the present invention, as Figures 4 to 8 shown, the sealing mechanism 6 includes an electric push rod 61. The output end of the electric push rod 61 is fixedly connected with a sealing plate 62. The fixed end of the electric push rod 61 is fixedly connected with an electromagnet. A positioning groove is opened at the top of the movable part of the telescopic rod 53. The bottom of the sealing plate 62 is fixedly connected with a positioning block for cooperating with the positioning groove for positioning. An additional telescopic rod 53 is also provided on the outer sides of the baffle 52 and the enclosure 54. The telescopic rod 53 includes a fixed part and a movable part. An anti-detachment groove is opened inside the fixed part. The outer side of the movable part is fixedly connected with an anti-detachment block for cooperating with the anti-detachment groove to prevent the movable part from sliding out from the inner side of the fixed part. The enclosure 54 is fixedly connected with the movable part of the telescopic rod 53, and the baffle 52 is fixedly connected with the fixed part of the telescopic rod 53. A return spring 55 is fixedly connected between the fixed part and the movable part. The electronic control component 510 includes a signal transmission module, a signal processing module and a power supply. The air valve detection component 58 includes an air valve and a humidity sensor and a temperature sensor installed outside the air valve. Both the temperature sensor and the humidity sensor are connected to the signal processing module through transmission lines. The signal processing module is connected to an external control display through the signal transmission module. The power supply is electrically connected to the signal processing module, the humidity sensor, the temperature sensor and the signal transmission module through wires. The bottom of the bottom support 51 is symmetrically and fixedly connected with a backing plate 59.

[0048] During operation, after being placed at the corresponding position on the three-dimensional layered rack mechanism 3, the electric push rod 61 is controlled to move downward. After the electric push rod 61 moves downward, it will drive the sealing plate 62 to move downward. When the sealing plate 62 moves downward, the alignment block at its bottom will first contact the alignment groove at the top of the movable part on the telescopic rod 53. As the sealing plate 62 continues to move downward, it will squeeze the movable part on the telescopic rod 53 into the inside of the fixed part. During this process, the movable part on the telescopic rod 53 will synchronously drive the enclosure 54 to slide into the inside of the baffle 52 until the enclosure 54 completely enters the inside of the baffle 52. At this time, the return spring 55 will also be compressed. Since through holes for ventilation are provided on both the enclosure 54 and the baffle 52, and when the enclosure 54 completely enters the inside of the baffle 52, the ventilation holes on the outside of the enclosure 54 and the baffle 52 will intersect and not contact each other. By cooperating with the bottom support 51 and the sealing plate 62, a sealed space is formed inside the storage mechanism 5.

[0049] As an embodiment of the present invention, as Figures 4 to 9 shown, a nitrogen generation device, an insecticidal gas generation device, a fire extinguishing device, a temperature and humidity detection and adjustment device, an air purification device, a lighting device, a power supply device, a control display, and the pipelines and lines required for the above-mentioned devices are provided in the intelligent warehouse 1. The gas control mechanism 7 includes a mounting frame 71 fixedly installed on the top of the sealing plate 62. An air conditioning component 73, a vacuum adjustment component 74, an insecticidal gas adjustment component 75, a nitrogen adjustment component 76, and a five-way electric control valve 77 are all arranged inside the mounting frame 71. A dust-proof and breathable cover 72 is provided on the top of the mounting frame 71. The air conditioning component 73 includes an air pump, a controller, and a signal transmission module. The air inlet of the air pump in the air conditioning component 73 is connected to the air purifier through a conduit, and the air outlet of the air pump in the air conditioning component 73 is connected to an air inlet on the five-way electric control valve 77 through a conduit; the vacuum adjustment component 74 includes a vacuum pump, a controller, and a signal transmission module. The suction port of the vacuum pump is connected to an air outlet on the five-way electric control valve 77; the insecticidal gas adjustment component 75 includes an air pump, a controller, and a signal transmission module. The air outlet of the air pump in the insecticidal gas adjustment component 75 is connected to an air inlet on the five-way electric control valve 77 through a conduit, and the air inlet of the air pump in the insecticidal gas adjustment component 75 is connected to the insecticidal gas generation device through a conduit; the nitrogen adjustment component 76 includes an air pump, a controller, and a signal transmission module. The air outlet of the air pump in the nitrogen adjustment component 76 is connected to an air inlet on the five-way electric control valve 77 through a conduit, and the air inlet of the air pump in the nitrogen adjustment component 76 is connected to the nitrogen generation device through a conduit; the air conditioning component 73, the vacuum adjustment component 74, the insecticidal gas adjustment component 75, the nitrogen adjustment component 76, and the five-way electric control valve 77 are all connected to the external power supply device through conducting wires.

[0050] During operation, corresponding instructions are transmitted to the main signal receiver at the corresponding position of the storage mechanism 5 through the control display, and the main signal receiver transmits the instructions to the corresponding signal transmission module. The following are the steps executed in sequence. First, the vacuum pump is controlled to start. The vacuum pump extracts the air in the sealed storage mechanism 5 through the five-way electric control valve 77, the conduit 78, the connecting column 56, the diaphragm 57 and the air valve detection component 58, so that a quasi-vacuum environment is formed inside the storage mechanism 5. Also, since the air valve in the air valve detection component 58 is arranged in the middle position of the storage mechanism 5, air is extracted from the inside of the grains, thereby accelerating the extraction speed of the gas inside the grains. After the inside of the storage mechanism 5 is evacuated, this state is maintained for about five days. During this process, a large number of pests inside the grains can be killed. For example, the mortality rate of adult rice weevils reaches 100% within 24 hours, and the eggs and pupae need 96 hours to be completely inactivated. Subsequently, the air pump in the air conditioning component 73 is controlled to open. The air conditioning component 73 discharges the fresh air purified by the air purification device from the air valve in the air valve detection component 58. The electric push rod 61 is started, and the electric push rod 61 drives the sealing plate 62 to open. At this time, the enclosure 54 resets, and the ventilation holes on the baffle 52 and the enclosure 54 are all opened. The gas discharged from the air valve detection component 58 will be discharged from the inside of the grains and discharged through the ventilation holes on the baffle 52 and the enclosure 54, so that the condensation generated inside the grains can be discharged in time. According to the moisture content of the grains, the humidity of the incoming air is controlled by the air purification device, thereby effectively maintaining the moisture content of the grains within a normal range. The ventilation is maintained for about three days. Subsequently, the electric push rod 61 is controlled to start. After the electric push rod 61 starts, the sealing plate 62 is re-covered on the storage mechanism 5, so that a closed space is formed again inside the storage mechanism 5. The vacuum pump is controlled to start to extract the gas inside the storage mechanism 5, and it stops working after extraction. The air pump in the nitrogen regulation component 76 is controlled to start. After the air pump in the nitrogen regulation component 76 starts, nitrogen will be transmitted to the inside of the storage mechanism 5. Since the inside of the storage mechanism 5 is in a vacuum state at this time, the nitrogen entering the inside of the storage mechanism 5 can quickly fill the inside of the grains. This operation can maximally remove the oxygen content inside the grains, not only enhancing the pest control effect, but also inhibiting the respiration of the grains, reducing the consumption of dry matter in the grains, delaying aging. This process lasts for six months. After that, the electric push rod 61 is started to open the sealing plate 62, and the air pump in the air conditioning component 73 is started to conduct air exchange inside the grains, and then the temperature and dryness of the discharged air are adjusted according to the humidity and temperature conditions of the grains. This process lasts for two days. Finally, the electric push rod 61 is started to close the sealing plate 62, and the previous step is repeated, that is, first vacuumize and then introduce nitrogen and maintain it for six months;

[0051] In all of the above steps, the humidity sensor and temperature sensor in the air valve detection component 58 are used to detect the temperature and humidity of the grain in real time. After the detected signals are processed by the signal processing module in the electronic control component 510, they are transmitted to the external control display through the signal transmission module. If the signals are abnormal, the electric push rod 61 is directly controlled to start and drive the sealing plate 62 to move upward. At the same time, the air pump in the air conditioning component 73 is started to ventilate the inside of the grain, and the temperature and humidity of the blown air are adjusted through the air purification equipment according to the specific abnormal signals.

[0052] If a large number of pests appear, the electric push rod 61 is started to drive the sealing plate 62 to move downward. First, the vacuum pump is started to evacuate the inside of the storage mechanism 5, and then the air pump inside the insecticidal gas adjustment component 75 is started to introduce the insecticidal gas into the inside of the storage mechanism 5. Under the vacuum condition, the insecticidal gas can quickly spread to all positions inside the grain, thereby accelerating the insecticidal effect. This process lasts for 15 days. According to the specific pest situation, the corresponding gas can be generated by the insecticidal gas generating equipment to achieve precise insecticidal. After the insecticidal is completed, the insecticidal gas inside the storage mechanism 5 is first pumped out by the vacuum pump, and then the air pump in the air conditioning component 73 is used to introduce air into the inside of the storage mechanism 5. This process lasts for one month to discharge the insecticidal gas attached to the outside of the grain. After one month, the electric push rod 61 is used to drive the sealing plate 62 to close the storage mechanism 5. After the vacuum pump evacuates the air, nitrogen is replenished and maintained for six months.

[0053] As an embodiment of the present invention, such as Figures 6 to 11As shown in the figure, an adaptive switching mechanism 8 is fixedly arranged at the bottom of the sealing plate 62. The adaptive switching mechanism 8 includes a connection frame 81 fixedly connected to the bottom of the sealing plate 62. A high-pressure nozzle 83 for spraying high-pressure gas is arranged at the bottom of the connection frame 81. A fixed frame 84 is fixedly connected to the top of the sealing plate 62. A switching frame 88 is arranged inside the fixed frame 84. A liquid storage frame 85 is fixedly connected to one side of the fixed frame 84. The inside of the liquid storage frame 85 is filled with a liquid that is easy to expand when heated. A sleeve 86 is fixedly connected to the inside of the fixed frame 84. A push rod 87 is slidably connected to the inside of the sleeve 86. A limiting groove is opened on the inner side of the sleeve 86. A limiting ring for cooperating with the limiting groove to prevent the push rod 87 from sliding out of the sleeve 86 is fixedly connected to one end of the push rod 87 arranged inside the sleeve 86. A sealing ring is fixedly connected to the outer side of the limiting ring. A switching block 89 is slidably connected to the inside of the switching frame 88. An adjusting hole 810 is opened on the switching block 89. A stepped groove 811 is also opened on the switching block 89. The adjusting hole 810 does not contact the stepped groove 811. A sleeve 812 with a spring inside is fixedly connected to the other side of the fixed frame 84. The output end of the sleeve 812 passes through the fixed frame 84 and the switching frame 88 and is fixedly connected to the switching block 89. The push rod 87 passes through the switching frame 88 and is fixedly connected to the switching block 89. Second communication holes 813 are opened on both the switching frame 88 and the fixed frame 84. A first communication hole 82 is opened on the connection frame 81. The second communication holes 813 are communicated with the first communication hole 82.

[0054] During operation, if a fire breaks out inside the intelligent warehouse 1, resulting in signal transmission interruption, the electromagnet on the storage mechanism 5 is basically in a power-off state at this time. If the storage mechanism 5 itself is in a sealed state, it can still be sealed under the gravity of the sealing mechanism 6 and the gas control mechanism 7. If the storage mechanism 5 itself is in an unsealed state, it will directly fall to the top of the storage mechanism 5 under the gravity of the sealing mechanism 6 and the gas control mechanism 7 to seal the storage mechanism 5. During this process, due to the limited distance between the sealing plate 62 and the telescopic rod 53, the appropriate spacing can be obtained through a limited number of experiments to increase the maximum probability of achieving sealing after falling. Due to signal transmission interruption and temperature rise, the high-temperature-expandable liquid inside the liquid storage frame 85 expands, and after the elastic force of the spring inside the sleeve 812 and the friction force between parts, it pushes the switching block 89 to move outward, so that nitrogen in the external pipeline can enter the inside of the connection frame 81 through the stepped groove 811, the second communication hole 813 and the first communication hole 82, and is sprayed out through the high-pressure nozzle 83 on the connection frame 81, thus preventing the fire from burning near the storage mechanism 5. And as the amount of nitrogen discharged into the intelligent warehouse 1 increases, it can also effectively suppress the fire inside the intelligent warehouse 1. In the above steps, the nitrogen generation equipment needs to work continuously to ensure an adequate amount of nitrogen. To avoid the nitrogen generation equipment, the air purification equipment and the insecticidal gas generation equipment being threatened by the fire, the nitrogen generation equipment, the air purification equipment and the insecticidal gas generation equipment can be placed outside the intelligent warehouse 1 or in a specific space.

[0055] Working principle:

[0056] Grain loading: Use the transport vehicle mechanism 2 to transport the storage mechanism 5 to the designated grain loading location, and load a certain amount of bulk grain into the storage mechanism 5 with the help of a feeding vehicle. After the grain is leveled, its height is slightly lower than the highest point of the baffle 52. At this time, the return spring 55 comes into play, pushing the movable part of the telescopic rod 53 and driving the enclosure 54 to move up to the highest position to prevent the grain from overflowing from around the baffle 52. After the grain loading is completed and leveled, the transport vehicle mechanism 2 transports the storage mechanism 5 loaded with grain to the palletizing machine mechanism 4. Finally, the palletizing machine mechanism 4 moves and places the storage mechanism 5 loaded with grain to the corresponding position of the three-dimensional layered rack mechanism 3.

[0057] Sealing construction: After the storage mechanism 5 is placed at the corresponding position of the three-dimensional layered rack mechanism 3, control the electric push rod 61 to move downward. The electric push rod 61 drives the sealing plate 62 to move downward. The alignment block at the bottom of the sealing plate 62 will first contact the alignment groove at the top of the movable part of the telescopic rod 53. As the sealing plate 62 continues to move downward, the movable part of the telescopic rod 53 is squeezed into the fixed part, and at the same time drives the enclosure 54 to slide into the baffle 52 until the enclosure 54 completely enters the baffle 52. At this time, the return spring 55 is compressed. Since both the enclosure 54 and the baffle 52 have ventilation holes, and when the enclosure 54 completely enters the baffle 52, the ventilation holes on their outer sides are staggered and do not contact each other. Coupled with the bottom tray 51 and the sealing plate 62, a sealed space is formed inside the storage mechanism 5.

[0058] Vacuuming to kill insects: By controlling the display to issue an instruction, the instruction is transmitted to the corresponding signal transmission module through the total signal receiver, and then the vacuum pump is started. The vacuum pump passes through the five-way electric control valve 77, the conduit 78, the connecting column 56, the diaphragm 57 and the air valve detection component 58 to pump out the air inside the sealed storage mechanism 5 to form a quasi-vacuum environment. Since the air valve in the air valve detection component 58 is located in the middle of the storage mechanism 5, it can pump air from the inside of the grain, accelerating the air extraction speed and maintaining this vacuum state for about 5 days, which can kill a large number of pests inside the grain. For example, the mortality rate of adult rice weevils reaches 100% within 24 hours, and the eggs and pupae need 96 hours to be completely inactivated.

[0059] Ventilation and moisture removal: Control the air pump in the air conditioning component 73 to open. The air conditioning component 73 discharges the fresh air purified by the air purification equipment from the air valve of the air valve detection component 58. At the same time, start the electric push rod 61. The electric push rod 61 drives the sealing plate 62 to open. At this time, the enclosure 54 resets, and the ventilation holes on the baffle 52 and the enclosure 54 open. The gas discharged from the air valve detection component 58 is discharged from the inside of the grain and discharged through the ventilation holes of the baffle 52 and the enclosure 54, thereby discharging the condensation inside the grain. According to the moisture content of the grain, control the humidity of the incoming air through the air purification equipment to maintain the moisture content of the grain within the normal range, and ventilate for about 3 days.

[0060] Nitrogen filling: Start the electric push rod 61 again to make the sealing plate 62 cover the storage mechanism 5 again to form a sealed space again. Start the vacuum pump to pump out the gas inside the storage mechanism 5 and then stop. Then control the air pump in the nitrogen regulation component 76 to start and transmit nitrogen into the storage mechanism 5. Since the inside of the storage mechanism 5 is in a vacuum state at this time, nitrogen can quickly fill the inside of the grain, removing the oxygen content inside the grain to the greatest extent, enhancing the insect prevention effect, inhibiting the respiration of the grain, reducing the consumption of dry matter, delaying aging, and this process lasts for 6 months.

[0061] Air exchange: Activate the electric push rod 61 to open the sealing plate 62, start the air pump in the air conditioning component 73, conduct air exchange inside the grains, adjust the temperature and dryness of the discharged air according to the humidity and temperature of the grains, continue for about 2 days, then close the sealing plate 62, and repeat the steps of first evacuating to vacuum and then filling with nitrogen and maintaining for 6 months.

[0062] Pest control: When a large number of pests appear, activate the electric push rod 61 to drive the sealing plate 62 to move downward. First, start the vacuum pump to evacuate the inside of the storage mechanism 5 to vacuum, and then start the air pump in the insecticidal gas adjustment component 75 to introduce the insecticidal gas into the storage mechanism 5. Under vacuum conditions, the insecticidal gas can quickly spread to all positions inside the grains, accelerating the pest control effect. This process lasts for 15 days. According to the specific pests, corresponding gases can be generated by the insecticidal gas generation equipment to achieve precise pest control. After the pest control is completed, first extract the insecticidal gas inside the storage mechanism 5 through the vacuum pump, and then introduce air into the storage mechanism 5 through the air pump in the air conditioning component 73 to maintain for 1 month to discharge the insecticidal gas attached to the outside of the grains. After 1 month, drive the sealing plate 62 to close the storage mechanism 5 through the electric push rod 61. After evacuating to vacuum with the vacuum pump, nitrogen is replenished and maintained for 6 months.

[0063] Temperature and humidity monitoring and adjustment: In all the above steps, the humidity sensor and temperature sensor in the air valve detection component 58 continuously monitor the temperature and humidity of the grains. After the detection signals are processed by the signal processing module in the electronic control component 510, they are transmitted to the external control display through the signal transmission module. If the signals are abnormal, directly control the electric push rod 61 to start and drive the sealing plate 62 to move upward, and at the same time start the air pump in the air conditioning component 73 to conduct ventilation treatment inside the grains, and adjust the temperature and humidity of the blown air through the air purification equipment according to the specific abnormal signals.

[0064] Fire emergency handling: If a fire breaks out inside the intelligent warehouse 1, causing signal transmission interruption, the electromagnets on the storage mechanism 5 are basically powered off. If the storage mechanism 5 was originally sealed, it remains sealed under the gravity of the sealing mechanism 6 and the gas control mechanism 7; if it was not sealed, it will directly fall to the top of the storage mechanism 5 to achieve sealing. Since the distance between the sealing plate 62 and the telescopic rod 53 is limited, the appropriate distance can be determined through a limited number of experiments to increase the sealing probability after falling. When the signal is interrupted and the temperature rises, the high-temperature-expandable liquid in the liquid storage frame 85 expands. Under the action of the spring force inside the sleeve 812 and the friction force of the parts, the switching block 89 is pushed outward, allowing nitrogen in the external pipeline to enter the connection frame 81 through the stepped groove 811, the second communication hole 813, and the first communication hole 82, and then sprayed out through the high-pressure nozzle 83 on the connection frame 81 to prevent the fire from spreading near the storage mechanism 5. As the amount of nitrogen discharged into the intelligent warehouse 1 increases, the fire can be effectively suppressed. During this process, the nitrogen generation equipment needs to continue working. To avoid the nitrogen generation equipment, air purification equipment, and insecticidal gas generation equipment being threatened by the fire, they can be placed outside the intelligent warehouse 1 or in a specific space.
