Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehouse ventilation technology, specifically a three-dimensional warehouse ventilation device. Background Technology
[0002] Automated storage and retrieval systems (AS / RS), also known as high-bay warehouses, typically use racks with several, a dozen, or even dozens of layers high to store unit goods. They use corresponding material handling equipment for inbound and outbound operations. AS / RS is a revolutionary achievement in logistics technology. It generally consists of high-rise racks, stacker cranes, conveyors, control systems, and a computer management system (WMS), which can automatically store and retrieve unit goods under the control of a computer system.
[0003] Existing warehouse ventilation systems may create ventilation dead zones due to the placement of shelves, resulting in poor ventilation. Some items may remain in poorly ventilated areas for extended periods, making them prone to dampness, mold, or unpleasant odors due to lack of air circulation, severely impacting their quality. Furthermore, most existing ventilation equipment operates at a fixed power level. When the warehouse has a small amount of stored goods and good air quality, excessive ventilation can lead to energy waste. On the other hand, when the warehouse has a large amount of stored goods, polluted air, or excessively high temperatures, it cannot provide sufficient ventilation to meet the actual needs.
[0004] Therefore, those skilled in the art have provided a three-dimensional warehouse ventilation device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a ventilation device for a three-dimensional warehouse to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A three-dimensional warehouse ventilation system includes a warehouse body with a warehouse roof fixedly connected to its top. Multiple circular ventilation holes are provided on both sides of the warehouse body. A support base is fixedly connected inside the warehouse body, and multiple air outlet pipes are inserted into the top of the support base. Multiple rectangular holes are formed on the surface of each air outlet pipe, arranged in a circular array. A pipe is inserted into one side of each ventilation hole, and a frequency converter is installed at one end of each pipe. An axial flow fan is fixedly connected to one side of the frequency converter. Square limiting holes are provided on both sides of the warehouse body. A filter screen is fixedly connected to one side of the ventilation hole. Multiple circular ventilation holes increase the air circulation area inside and outside the warehouse, making it easier for air to enter and exit the warehouse and effectively promoting air circulation. At the same time, the exhaust duct can further guide the air flow, distributing the air evenly to different areas inside the warehouse through the rectangular holes, making the ventilation effect more uniform and avoiding poor local ventilation. This ensures that items in all locations within the warehouse receive good ventilation. Furthermore, operators can flexibly adjust the speed of the axial flow fan according to the actual ventilation needs of the warehouse through the frequency converter, thereby controlling the amount of ventilation and improving the flexibility of the device in use.
[0008] As a further improvement of this utility model: a connecting frame is fixedly connected to the other side of the square limiting hole, a fixed shaft is fixedly connected to the surface of the connecting frame, a hydraulic rod is fixedly connected to one side of the connecting frame, a mounting bracket is fixedly connected to one end of the hydraulic rod, a connecting rod is connected through the bottom of the mounting bracket, and arc-shaped grooves are opened on both sides of the mounting bracket. The arc-shaped grooves are sleeved on the outside of the fixed shaft, and a cooling fan is snapped onto one side of the mounting bracket. The extension and retraction of the hydraulic rod can push the mounting bracket to move. Due to the cooperation between the arc-shaped grooves and the fixed shaft, the mounting bracket will rotate around the fixed shaft during the movement, thereby changing the position and angle of the cooling fan. This allows the cooling fan to be precisely adjusted to the optimal position according to the temperature distribution and heat dissipation needs of different areas in the warehouse, achieving effective heat dissipation for specific areas and improving heat dissipation efficiency and targeting.
[0009] As a further improvement of this utility model: a sealing film is provided between the main body of the warehouse and the warehouse roof, a waterproof layer is provided on the top of the sealing film, and a guide plate is provided on the top of the sealing film. The guide plate is wider at both sides and narrower in the middle. The sealing film, as a basic waterproof layer, is tightly attached between the main body of the warehouse and the warehouse roof, which can effectively prevent rainwater, snow water and other water from seeping into the warehouse from the roof gaps, providing the first waterproof barrier for the warehouse. The waterproof layer further enhances the waterproof ability of the sealing film, prevents moisture from staying on the surface of the sealing film for a long time and penetrating, and ensures that the inside of the warehouse always remains dry.
[0010] As a further improvement of this utility model: ventilation openings are provided on both sides of the warehouse roof, and a protective net is provided on one side of each ventilation opening. Rain shields are fixedly connected to both sides of the warehouse roof. The ventilation openings on both sides of the warehouse roof provide a direct channel for air exchange between the inside and outside of the warehouse. When there is a pressure difference or temperature difference between the inside and outside of the warehouse, the air will naturally flow through the ventilation openings to achieve ventilation. This helps to remove odors, moisture and heat from the warehouse, introduce fresh air, keep the air inside the warehouse fresh and dry, and provide a good storage environment for stored goods. At the same time, the protective net can effectively block external debris, insects, birds and other objects from entering the warehouse.
[0011] As a further improvement of this utility model: a connecting seat is fixedly connected to the top of the warehouse roof, and a photovoltaic panel is fixedly connected to the top of the connecting seat. The photovoltaic panel can convert solar energy into electrical energy, providing green and sustainable energy for ventilation equipment, lighting systems and other electrical equipment in the warehouse, reducing dependence on traditional power grids and lowering the energy consumption cost of the warehouse.
[0012] As a further improvement of this utility model: sound insulation cotton is installed on the exterior of both the axial flow fan and the cooling fan, and a temperature sensor is installed inside the main body of the warehouse. The axial flow fan and the cooling fan will generate a lot of noise during operation. The sound insulation cotton can effectively absorb and block the noise generated by the fan and the cooling fan, reduce the propagation range and intensity of the noise, and create a relatively quiet working and storage environment for the warehouse. At the same time, the temperature sensor can monitor the temperature changes inside the main body of the warehouse in real time and transmit the temperature data to the control system in a timely manner, so that warehouse managers can understand the temperature status inside the warehouse at any time and detect abnormal temperature conditions in a timely manner.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Multiple circular ventilation holes increase the air circulation area inside and outside the warehouse, making it easier for air to enter and exit the warehouse and effectively promoting air circulation inside the warehouse. At the same time, the air outlet duct can further guide the air flow, and distribute the air evenly to different areas inside the warehouse through the rectangular holes, making the ventilation effect more uniform and avoiding poor local ventilation. This ensures that items in all locations in the warehouse can receive good ventilation. In addition, the operator can flexibly adjust the speed of the axial flow fan according to the actual ventilation needs in the warehouse through the frequency converter, thereby controlling the amount of ventilation and improving the flexibility of the device in use.
[0015] 2. The extension and retraction of the hydraulic rod can push the mounting frame to move. Due to the cooperation between the arc groove and the fixed shaft, the mounting frame will rotate around the fixed shaft during the movement, thereby changing the position and angle of the cooling fan. This allows the cooling fan to be precisely adjusted to the optimal position according to the temperature distribution and heat dissipation requirements of different areas in the warehouse, achieving effective heat dissipation for specific areas and improving heat dissipation efficiency and targeting.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1
[0023] Reference Figure 1 - Figure 4This embodiment provides a three-dimensional warehouse ventilation device, including a warehouse body 1, a warehouse roof 2 fixedly connected to the top of the warehouse body 1, multiple circular ventilation holes 3 on both sides of the warehouse body 1, a support base 4 fixedly connected inside the warehouse body 1, multiple air outlet pipes 5 inserted into the top of the support base 4, multiple rectangular holes 6 on the surface of the multiple air outlet pipes 5, the multiple rectangular holes 6 being arranged in a ring array, a pipe 7 inserted into one side of each of the multiple ventilation holes 3, a frequency converter 8 installed at one end of the pipe 7, an axial flow fan 9 fixedly connected to one side of the frequency converter 8, and square limiting holes 10 on both sides of the warehouse body 1, one side of the square limiting holes 10 being fixedly connected to... A filter screen 11 is connected to the other side of the square limiting hole 10, and a connecting frame 12 is fixedly connected to it. A fixed shaft 13 is fixedly connected to the surface of the connecting frame 12. A hydraulic rod 14 is fixedly connected to one side of the connecting frame 12. A mounting bracket 15 is fixedly connected to one end of the hydraulic rod 14. A connecting rod 16 is connected through the bottom of the mounting bracket 15. Arc-shaped grooves 17 are opened on both sides of the mounting bracket 15. The arc-shaped grooves 17 are fitted onto the outside of the fixed shaft 13. A cooling fan 18 is snapped onto one side of the mounting bracket 15. The axial flow fan 9 starts to operate under the control of the frequency converter 8. The axial flow fan 9 generates a strong suction force, which continuously introduces fresh air from the outside into the warehouse body 1 through the ventilation hole 3 via the pipe 7. The device 8 can flexibly adjust the speed of the axial flow fan 9 according to the actual ventilation needs of the warehouse. When the air pollution level and temperature in the warehouse are high, the speed of the axial flow fan 9 is increased to increase the introduction of fresh air; conversely, the speed is reduced to maintain a suitable ventilation volume. The fresh air entering the warehouse flows in the warehouse and mixes with the existing air. Multiple air outlet pipes 5 inserted on the support base 4 have multiple rectangular holes 6 arranged in a ring array on their surface, which can evenly distribute the air introduced by the axial flow fan 9 to different areas inside the warehouse, making the ventilation effect more uniform and avoiding localized poor ventilation. At the same time, when the temperature in the warehouse is high and the introduction of fresh air by the axial flow fan 9 alone cannot effectively reduce the temperature, the liquid... When the pressure rod 14 starts working, the hydraulic rod 14 extends and retracts, pushing the mounting bracket 15 to rotate around the fixed shaft 13 within the range defined by the arc groove 17, thereby adjusting the angle of the cooling fan 18. After the cooling fan 18 starts, it accelerates the exhaust of hot air from the warehouse. At the same time, it works in conjunction with the cold air introduced by the axial flow fan 9 to accelerate the air convection speed and enhance the heat dissipation effect. During the ventilation process, dust and impurities in the outside air will enter along with the fresh air. At this time, the filter screen 11 fixedly connected to one side of the square limiting hole 10 plays a filtering role, blocking dust and impurities from entering the warehouse and preventing them from contaminating the goods stored in the warehouse, ensuring the cleanliness of the air in the warehouse and maintaining a good storage environment.
[0024] Example 2
[0025] Reference Figure 1 - Figure 4This embodiment is based on the previous embodiment, but differs in that a sealing film 19 is provided between the warehouse body 1 and the warehouse roof 2. A waterproof layer 20 is provided on the top of the sealing film 19, and a guide plate 21 is provided on the top of the sealing film 19. The guide plate 21 is wider at both sides and narrower in the middle. Ventilation openings 22 are provided on both sides of the warehouse roof 2, and a protective net 23 is provided on one side of each ventilation opening 22. Rainproof plates 24 are fixedly connected to both sides of the warehouse roof 2. A connecting seat 25 is fixedly connected to the top of the warehouse roof 2, and a photovoltaic panel 26 is fixedly connected to the top of the connecting seat 25. Sound insulation cotton 27 is provided on the outside of both the axial flow fan 9 and the cooling fan 18. A temperature sensor 28 is provided inside the warehouse body 1 to monitor the temperature inside the warehouse in real time. When the temperature is high and the axial flow fan 9 alone cannot effectively reduce the temperature by introducing fresh air, the cooling fan 18 will be activated to dissipate heat. During the ventilation process, dust and impurities in the outside air will enter along with the fresh air. At the same time, the filter screen 11 fixedly connected to one side of the square limiting hole 10 plays a filtering role, blocking dust, impurities and other contaminants from entering the warehouse, preventing them from contaminating the goods stored in the warehouse, ensuring the cleanliness of the air in the warehouse, and maintaining a good storage environment. Secondly, the sealing film 19 and waterproof layer 20 between the warehouse body 1 and the warehouse roof 2 are tightly fitted together, effectively preventing rainwater from seeping into the warehouse, and protecting the goods in the warehouse from moisture in all directions. The guide plate 21 set on the top of the sealing film 19, due to its special shape of being wide on both sides and narrow in the middle, can guide the wind direction to carry away the heat of the warehouse roof 2. The ventilation openings 22 and protective nets 23 set on both sides of the warehouse roof 2 assist the air in the warehouse to be discharged. The protective nets 23 prevent foreign objects from entering through the ventilation openings 22, and the rain shield 24 further prevents rainwater from entering the warehouse through the ventilation openings 22, ensuring the dryness of the ventilation openings 22. At the same time, the photovoltaic panels 26 on the warehouse roof 2 can convert solar energy into electrical energy to provide power for some electrical equipment, realizing the effective use of energy and energy conservation and emission reduction, and reducing warehouse operating costs.
