Description

A prefabricated grain warehouse Technical Field

[0001] This invention relates to the field of grain warehouse technology, specifically a prefabricated grain warehouse. Background Technology

[0002] A flat-roofed grain warehouse refers to a single-story grain warehouse that stores grain and meets the requirements of grain storage. It is also known as a "flat-roofed grain warehouse" or "house-type grain warehouse". Prefabricated flat-roofed grain warehouses refer to flat-roofed warehouses that are quickly assembled using steel structures. Compared with traditional concrete-poured flat-roofed warehouses, they have higher construction efficiency and are simpler to build.

[0003] A search revealed that the patent number CN219491876U, entitled "An Invention of a Cast-in-Place Sloping Roof Tall Grain Warehouse," includes a warehouse body with a triangular roof and a double-layered roof. The double-layered roof comprises a cast-in-place sloping roof slab and photovoltaic tiles or color steel plates installed on the sloping roof slab. Research and analysis revealed that although the cast-in-place sloping roof tall grain warehouse has good air convection effect on the roof, enabling natural ventilation and heat dissipation and reducing the energy consumption for temperature control, it still has the following drawbacks to some extent.

[0004] For example, the above-mentioned flat grain warehouses are constructed by concrete pouring, which has low construction efficiency and makes it impossible to monitor the ambient temperature and humidity inside the warehouse. Staff cannot obtain real-time information about the environment inside the warehouse. In addition, the heat dissipation efficiency through natural ventilation is low. At the same time, in heavy rain, rainwater can easily flow into the warehouse through the ventilation openings, causing the grain to become damp and moldy. In order to solve the above technical problems, we have designed a prefabricated flat grain warehouse. Summary of the Invention

By setting the rain shelter 15, the lower part of the door panel 14 can be protected from rain, preventing rainwater from entering the flat warehouse through the gaps in the door panel 14. By setting the monitoring camera 4, the perimeter of the flat warehouse can be photographed and monitored to prevent criminals from stealing grain from the flat warehouse.

[0039] Ultrasonic bird repellers 6 are bolted to both the front and rear sides of the top cover 5. The output end of the main control box 13 is electrically connected to the input end of the ultrasonic bird repeller 6. By setting the ultrasonic bird repeller 6, the bird repeller has the function of repelling birds. The ultrasonic bird repeller 6 is a physical bird repeller method. It uses an ultrasonic pulse to interfere with and damage the nervous and physiological systems of birds, causing them to become physiologically disordered in order to achieve the ultimate purpose of repelling birds. The ultrasonic waves used have the characteristics of not being able to penetrate obstacles, strong directionality, and fast attenuation. Therefore, a high-power bird repeller is used to propagate the ultrasonic waves through countless reflections, forming an ultrasonic protective net that covers the entire bird-repelling space. This can prevent birds from entering the flat warehouse from the openings on the front and rear sides when the top cover 5 is raised.

[0046] The drive mechanism 8 includes a mounting box 23. Supporting vertical plates are welded to the left and right sides of the bottom of the inner cavity of the mounting box 23. The rear supporting vertical plate is connected to the drive motor 19 by bolts. The output shaft of the drive motor 19 passes through the supporting vertical plate and is fixedly connected to the drive screw 21. The front side of the drive screw 21 is movably connected to the front supporting vertical plate by a bearing. Sliding blocks 20 are threaded on both the front and rear sides of the surface of the drive screw 21. The top of the sliding block 20 is movably connected to the support push rod 22 by a pin. The top of the support push rod 22 is movably connected to the mounting slide plate 18 by a pin. The front and rear sides of the surface of the drive screw 21 are respectively provided with left-hand threads and right-hand threads. The output end of the main control box 13 is electrically connected to the input end of the drive motor 19. By setting the mounting box 23, it has the function of installation limit, which can facilitate the installation of the drive motor 19 and the drive screw 21, and at the same time make the mounting slide plate 18 move up and down more smoothly inside.

[0047] The top cover 5 includes a supporting top plate 29. The top of the supporting top plate 29 is bolted to the cover body 30. Sealing inserts 28 are welded to the front and rear sides of the bottom of the supporting top plate 29. The left and right sides of the bottom of the supporting top plate 29 are fixedly connected to the mounting slides 18 on the left and right sides, respectively. By setting the sealing inserts 28, the sealing performance is improved. They can be inserted into the sealing slots 27 at the top of the first side plate 11 to improve the sealing performance between the supporting top plate 29 and the first side plate 11, preventing rainwater or insects from entering. By setting the supporting top plate 29, the cover body 30 is supported and fixed, and the mounting slides 18 and the cover body 30 are connected.

[0048] A method for using a prefabricated, modular grain storage facility, with the following specific operating steps:

[0049] A: Install the bottom of the four corner support columns 1 onto the surface of the pre-embedded bolts and tighten the nuts for fixed installation. Install the first side plates 11 on the front and rear sides between the support columns 1 on the left and right sides using bolts. Then fix the drive mechanism 8 and the second side plate 10 between the support columns 1 on the front and rear sides. Then fix the bottom of the support top plate 29 on the left and right sides to the top of the mounting slide plates 18 on the left and right sides using bolts. In this way, the flat warehouse can be assembled. Compared with the traditional concrete-poured flat warehouse, the prefabricated flat warehouse has higher construction efficiency and is more convenient to construct.

[0050] B: The monitoring unit 26 can monitor the temperature and humidity inside the bungalow in real time. The monitored data is transmitted to the main control box 13. After processing by the main control box 13, the information is transmitted to the electronic display panel 12. The temperature and humidity information is displayed numerically on the electronic display panel 12 for management personnel to view. When the temperature and humidity inside the bungalow are high, the main control box 13 controls the drive motors 19 on the left and right sides to drive the drive screws 21 to rotate forward. The forward rotation of the drive screws 21 causes the sliding blocks 20 on the front and rear sides of the surface to move relative to each other. The relatively moved sliding blocks 20 push the mounting plate 18 upward and out of the mounting box 23 through the support push rod 22. At this time, the top cover 5 is lifted accordingly. As shown in Figure 3, the ventilation fans 17 on both sides are then controlled to blow outside air inwards. The air flows out through the openings on the front and rear sides. Due to the high air velocity at the top, the air inside the flat warehouse flows upwards under atmospheric pressure and flows out through the openings on both sides. This can quickly ventilate and dissipate heat inside the flat warehouse, improving heat dissipation efficiency. When encountering heavy rain, the ventilation fans 17 on both sides are controlled to stop working, and then the drive motors 19 on both sides are controlled to drive the drive screws 21 to reverse. This causes the sliding blocks 20 on the front and rear sides to move in the opposite direction, which allows the mounting plate 18 to descend and reset. At the same time, the top cover 5 descends and closes, which can prevent rainwater from flowing into the flat warehouse and causing the grain to become damp.

[0051] C: By setting up photovoltaic panels 7, solar energy can be converted into electrical energy and stored in battery pack 16 for use by the equipment, which is more energy-efficient and environmentally friendly. By setting up flame-retardant layer 33 and fireproof coating 35, the prefabricated flat warehouse can have good fire-retardant performance, effectively preventing the spread of external fire and avoiding damage to the grain in the flat warehouse.

[0052] In summary, this prefabricated grain warehouse, through the coordinated use of supporting columns 1, mounting base 2, top cover 5, photovoltaic power generation panel 7, drive mechanism 8, electronic display panel 12, battery pack 16, ventilation fan 17, mounting slide plate 18, and monitoring mechanism 26, solves the problems of low construction efficiency, inability to monitor the environment inside the warehouse in real time, inconvenience for personnel management, and low ventilation and heat dissipation efficiency of traditional construction methods.

[0053] Example 2:

[0054] As shown in Figure 7-12, the difference between this embodiment and embodiment 1 is that an automatic ventilation mechanism that changes according to seasonal differences is also designed. This embodiment 2 mainly describes this difference.

[0055] Designed to accommodate varying seasonal storage and adjustment requirements of grain warehouses:

[0056] (1) Spring

[0057] In the spring when temperatures rise, the focus of grain storage management is on insulating and keeping grain piles cool, which is a crucial step in achieving "low-temperature grain storage." New grain storage facilities often have large piles, and especially under enclosed, non-circulating conditions, the poor thermal conductivity of grain becomes more pronounced. In spring, this characteristic should be utilized to ensure proper insulation and sealing of the storage facility and to cover and insulate the grain piles to slow the rate of temperature rise and ensure the safety of stored grain.

[0058] (2) Summer

[0059] For normal grain piles, grain in normal condition at low temperatures does not require ventilation in summer; the management focus at this time is maintaining the low temperature of the grain pile. For large grain piles cooled during winter, taking advantage of their good insulation properties, the grain temperature remains low and the condition relatively stable in summer, making ventilation unnecessary and disrupting the low-temperature state. In summer, rice storage facilities in southern regions should take advantage of the lower outside temperature compared to the storage temperature to lower the storage temperature. This is a crucial measure to prevent grain temperature rise and maintain grain quality. During the cooler nighttime hours, open storage windows and activate exhaust fans on the storage walls or ventilation fans on the arched roof of the storage facility to ensure timely ventilation and lower the storage temperature or the temperature of the arched partitions, thus slowing the rate of grain temperature rise. In this case, the ventilation structure on the roof of a flat storage facility can be used for ventilation.

[0060] Abnormal grain pile

[0061] During the hot summer months, the key to managing abnormal grain piles is to first prevent them from overheating, and then seek opportunities to reduce moisture. Due to the poor thermal conductivity of large grain piles, heat and moisture can accumulate inside, causing the pile to overheat and mold. In this case, it's necessary to implement high-volume ventilation to cool and dissipate moisture, preventing overheating and eliminating potential storage hazards. Alternatively, grain coolers can be used to lower the storage temperature, slowing the rate of temperature rise and ensuring the grain remains at a low temperature. Another option is to use high-concentration aluminum phosphide fumigation before the grain overheats to inhibit mold growth, and then ventilate and reduce moisture when the time is right to ensure safe grain storage.

[0062] (3) Autumn

[0063] As autumn deepens, the focus of grain storage management should shift to phased ventilation and preventing condensation on grain piles. When outside temperatures drop, the good insulation properties of large grain piles can easily create a "cold outside, hot inside" environment inside new grain storage areas. This can lead to moisture transfer within the grain pile, causing condensation to form on the surface and walls, eventually resulting in mold growth and heat generation. Therefore, timely ventilation is crucial to dissipate moisture, equalize grain temperature, eliminate conditions conducive to moisture transfer, and prevent condensation on the surface and walls.

[0064] (4) Winter

[0065] During the cold winter, the key to grain storage management is to seize the opportunity to ventilate and lower the temperature of the grain pile. In winter, we should make full use of the natural low temperature conditions to ventilate and cool the grain, creating a low-temperature storage environment in the grain warehouse, and creating conditions for a low-temperature summer in the following year.

[0066] Designed to meet different seasonal ventilation needs, the mounting base 2 is equipped with a ventilation mechanism for switching ventilation modes. This mechanism includes bottom ventilation channels 101 arranged side-by-side on the mounting base, bottom vent holes 102 evenly distributed on the mounting base corresponding to the bottom ventilation channels, and side wall ventilation channels 103 installed inside the second side plate 10 corresponding to the bottom ventilation channels. Side wall vent holes 104 are evenly distributed on the inner side wall of the second side plate corresponding to the side wall ventilation channels.

[0067] The specific working mode is as follows:

[0068] Mode 1: The first vent is connected to the fourth vent, the second vent is connected to the fifth vent, and the third vent is connected to the sixth vent. At this time, the outdoor air, the side wall exhaust channel, and the bottom exhaust channel are all connected. The airflow direction can be switched as needed to fully realize the rapid heat exchange between the outdoor air and the bottom and side walls of the grain silo.

[0069] Mode 2: The second vent is connected to the fourth vent, and the third vent is connected to the fifth vent. At this time, the side wall exhaust channel and the bottom exhaust channel are connected and isolated from the outdoor air, realizing the self-circulation of internal heat and preventing the accumulation of heat in a single point in the grain silo.

[0070] Mode 3: The first vent is connected to the sixth vent, and the third vent is connected to the fourth vent. At this time, the outdoor air and the bottom exhaust channel are connected, and the side wall exhaust channel is closed; targeted heat exchange is carried out at the bottom of the grain silo.

[0071] Mode 4: The first vent connects to the fifth vent, and the second vent connects to the sixth vent. In this mode, outdoor air and the side wall exhaust channels are connected, while the bottom exhaust channel is closed, allowing for targeted heat exchange on the grain silo side walls. The appropriate mode is selected based on the suitable heat dissipation area and method, thereby changing the ventilation method.
