Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 6This utility model provides a technical solution: a container with an automatic ventilation system, including a container body 1. Both ends of the upper surface of the container body 1 are provided with mounting slots. An automatic ventilation component 2 can be detachably connected to each mounting slot. Each automatic ventilation component 2 includes a mounting frame 201 and two connecting filter plates 202. A filter screen 203 is provided in the middle of each of the two connecting filter plates 202. Each connecting filter plate 202 has a mounting slot 204 on its surface facing the mounting frame 201. The mounting frame 201 is engaged between two corresponding mounting slots 204. Each connecting filter plate 202 has through holes at its four corners for inserting fasteners, which are then connected to the top surface and inner wall of the container body 1 via fasteners. The mounting frame 201 contains a fan mechanism, an automatic opening and closing mechanism, and a displacement adjustment mechanism. A sensor module is also integrated on the connecting filter plate 202 located inside the container body 1. The sensor module is electrically connected to the fan mechanism, the automatic opening and closing mechanism, and the displacement adjustment mechanism.

[0023] Please see Figures 3 to 6 The top of the inner walls on both sides of the mounting frame 201 are integrally provided with an extension portion extending inward, and a ventilation gap is provided between the two extension portions. The fan mechanism is located below the ventilation gap. The automatic opening and closing mechanism includes two sliding plates 205. Each sliding plate 205 has a connecting slide bar 206 integrally provided at both ends of its upper surface. Each connecting slide bar 206 is slidably connected in a corresponding connecting slide groove 207. Each connecting slide groove 207 is opened on the bottom surface of the corresponding side extension portion. The two sliding plates 205 are simultaneously connected to the synchronous drive mechanism.

[0024] The connecting strip 206 on the sliding plate 205 is slidably connected to the connecting groove 207 at the bottom of the extension. A synchronous drive mechanism drives the two sliding plates 205 to slide simultaneously. When ventilation needs to be increased, the synchronous drive mechanism causes the two sliding plates 205 to slide to the sides, widening the ventilation gap; when ventilation needs to be reduced or shut off, the two sliding plates 205 slide towards the center, narrowing or closing the ventilation gap. The automatic opening and closing mechanism can precisely control the ventilation volume according to the environmental requirements inside the container, avoiding unnecessary ventilation and saving energy. In severe weather conditions, such as heavy rain or sandstorms, the ventilation gap can be closed to prevent rainwater and sand from entering the container, protecting the cargo. In practical applications, sealing strips can be installed on the sliding plates 205 to improve sealing performance when the ventilation gap is closed, further preventing external dust and moisture from entering. A position sensor can also be added to monitor the position of the sliding plates 205 in real time for more precise control of the ventilation gap size.

[0025] Furthermore, the synchronous drive mechanism includes two connecting ears 208. One end of each connecting ear 208 is fixedly connected to the bottom surface of the corresponding sliding plate 205. The other end of each connecting ear 208 is provided with a screw hole and is threadedly connected to a corresponding first screw 209 through the screw hole. The two first screws 209 have opposite thread directions and one end is rotatably connected to the inner wall of the corresponding side of the mounting frame 201. The other ends of the two first screws 209 are fixedly connected to the output shaft end of the corresponding side of the dual-axis motor 210. The dual-axis motor 210 is fixedly installed on the inner wall of the other side of the mounting frame 201.

[0026] A dual-axis motor 210 is fixedly mounted on one inner wall of the mounting frame 201 and has forward and reverse rotation functions. Its two output shafts are fixedly connected to one end of each of the two first screws 209. The other end of each first screw 209 is rotatably connected to the corresponding inner wall of the mounting frame 201. One end of a connecting lug 208 is fixedly connected to the bottom of a sliding plate 205, and the other end is threadedly connected to the first screw 209 through a screw hole. When the dual-axis motor 210 rotates, the two first screws 209 rotate synchronously. Because the threads are in opposite directions, they drive the two sliding plates 205 to slide synchronously in opposite directions, making the opening and closing of the ventilation gap more stable and uniform. In practical applications, an encoder can be installed on the dual-axis motor 210 to monitor the motor's speed and rotation angle in real time, thereby more accurately controlling the sliding distance and speed of the sliding plate 205. A backup power supply can also be set up to ensure that the dual-axis motor 210 can continue to work for a period of time in the event of a main power failure, maintaining the basic functions of the ventilation system.

[0027] Furthermore, the fan mechanism includes a displacement mounting plate 211, which is slidably connected between the inner walls of both sides of the mounting frame 201 via a displacement adjustment mechanism. The displacement adjustment mechanism includes two connecting plates 212, a guide slide rod 213, and a second screw 214. One end of each of the two connecting plates 212 is fixedly connected to the two surfaces of the displacement mounting plate 211. The guide slide rod 213 is fixedly connected between the inner walls of both sides of the mounting frame 201 and extends in the same direction as the ventilation gap. One end of the second screw 214 is rotatably connected to the inner wall of one side of the mounting frame 201, and the other end is fixedly connected to one end of the output shaft of the first drive motor 215. The first drive motor 215 is fixedly installed on the inner wall of the other side of the mounting frame 201. The guide slide rod 213 and the second screw 214 are arranged in parallel and are positioned on both sides of the displacement mounting plate 211. The other ends of the connecting plates 212 on both sides of the displacement mounting plate 211 are slidably connected to the guide slide rod 213 and the second screw 214 on the corresponding side through sliding holes and threaded holes, respectively.

[0028] The displacement mounting plate 211 is connected to the guide slide rod 213 and the second screw 214 via connecting plates 212 on both sides. The guide slide rod 213 is fixedly connected between the inner walls on both sides of the mounting frame 201, serving a guiding function. One end of the second screw 214 is rotatably connected to the inner wall on one side of the mounting frame 201, and the other end is fixedly connected to the output shaft of the first drive motor 215. The first drive motor 215 also has forward and reverse rotation functions. When the first drive motor 215 rotates, it drives the second screw 214 to rotate. The displacement mounting plate 211 is threadedly connected to the second screw 214 through the threaded hole on the connecting plate 212. Guided by the guide slide rod 213, it reciprocates along the ventilation gap direction as the second screw 214 rotates. The reciprocating movement of the fan mechanism can cover a larger ventilation area, avoid ventilation dead zones, and allow for more thorough air exchange inside the container. The position of the fan can be flexibly adjusted according to the stacking of goods inside the container and ventilation requirements to improve ventilation efficiency. When applying the device, a displacement sensor can be set to monitor the position of the displacement mounting plate 211 in real time, so as to accurately control the displacement range and speed of the fan mechanism according to actual needs.

[0029] Furthermore, the upper surface of the displacement mounting plate 211 has four mounting openings 216, which are arranged in a square. Each mounting opening 216 has a mounting ring 218 fixedly connected to its inner wall by several connectors 217. Each mounting ring 218 is coaxially arranged with the corresponding mounting opening 216, and a mounting shaft 219 is rotatably mounted in the mounting ring 218. Each mounting shaft 219 has several fan blades 220 evenly distributed in a ring fixedly connected to its top circumference outer wall. The bottom ends of the four mounting shafts 219 are connected to the drive device through a transmission mechanism.

[0030] The upper surface of the displacement mounting plate 211 has four square mounting openings 216. The inner walls of the mounting openings 216 are fixedly connected to mounting rings 218 via connectors 217. Mounting shafts 219 are rotatably mounted within the mounting rings 218. The drive unit drives the four mounting shafts 219 to rotate synchronously via a transmission mechanism, causing the fan blades 220 to rotate and generate airflow. The square-distributed mounting openings 216 ensure more uniform airflow distribution, enabling better circulation and exchange of air within the container. In specific applications, adjustable-angle fan blades 220 can be used. The direction and intensity of the airflow can be changed by adjusting the angle of the fan blades 220 according to different ventilation requirements. An antibacterial coating can also be applied to the surface of the fan blades 220 to reduce the growth of bacteria and microorganisms on the blades.

[0031] Furthermore, the transmission mechanism includes four driven gears 221, each driven gear 221 is fixedly sleeved on the bottom end of the corresponding mounting shaft 219, and a drive gear 222 is arranged between the four driven gears 221. The drive gear 222 meshes with the four driven gears 221 and is fixedly sleeved on the rotating shaft 223. One end of the rotating shaft 223 is rotatably connected to the bottom surface of the displacement mounting plate 211, and the other end of the rotating shaft 223 is also fixedly sleeved with a first bevel gear 224. The first bevel gear 224 meshes with a second bevel gear 225 on one side. The second bevel gear 225 is fixedly sleeved on the end of the output shaft of the second drive motor 226. The second drive motor 226 is fixedly mounted on the bottom side of the displacement mounting plate 211 through the mounting bracket 227.

[0032] The second drive motor 226 is fixedly mounted on one side of the bottom of the displacement mounting plate 211 via a mounting bracket 227, and a second bevel gear 225 is fixedly sleeved on the end of its output shaft. The second bevel gear 225 meshes with a first bevel gear 224, which is fixedly sleeved on a rotating shaft 223. One end of the rotating shaft 223 is rotatably connected to the bottom surface of the displacement mounting plate 211, and the other end is fixedly sleeved with a drive gear 222. The drive gear 222 simultaneously meshes with four driven gears 221, which are fixedly sleeved on the bottom end of the mounting shaft 219. When the second drive motor 226 rotates, it drives the four mounting shafts 219 to rotate synchronously through bevel gear and gear transmission. Gear transmission has the characteristics of high transmission efficiency and stable transmission ratio, ensuring the synchronous rotation of the four fan blades 220, making the airflow more stable and uniform. The second drive motor 226 can have forward and reverse rotation functions. By changing the rotation direction of the mounting shaft 219, it can change the airflow direction and switch between two states: extracting air from the container body 1 and injecting air into the container body 1, thereby meeting different ventilation needs.

[0033] Furthermore, the sensor module includes a controller, a temperature sensor, a humidity sensor, and a harmful gas sensor. The controller is electrically connected to the temperature sensor, humidity sensor, harmful gas sensor, automatic opening and closing mechanism, fan mechanism, and displacement adjustment mechanism, respectively.

[0034] Temperature, humidity, and hazardous gas sensors transmit monitored data to the controller, which compares this data with preset thresholds. If the monitored data exceeds the threshold, the controller sends corresponding control signals to adjust the size of the ventilation gap using an automatic opening and closing mechanism, and to control the speed and displacement adjustment mechanism of the fan mechanism to regulate the environmental conditions inside the container. The sensor module enables the ventilation system to automatically adjust ventilation based on the actual environmental conditions inside the container, improving the accuracy and efficiency of ventilation. Monitoring hazardous gases can promptly detect safety hazards such as cargo leaks, ensuring the safety of cargo transportation. In specific applications, other types of sensors can be added, such as air quality sensors, to monitor particulate matter concentration, volatile organic compounds, and other air quality indicators inside the container, further improving the environmental monitoring function of the ventilation system. The sensor module can also be connected to a remote monitoring system to achieve remote real-time monitoring and control of the environment inside the container.

[0035] Working principle: An automatic ventilation assembly 2 is installed on the container body 1. The sensor module in the assembly is integrated on the internal connecting filter plate 202. The sensor module, which includes sensors for temperature, humidity, and harmful gases, transmits the monitored environmental data inside the container to the controller. The controller compares the data with preset thresholds. If the data exceeds the threshold, the controller sends a control signal. In the automatic opening and closing mechanism, the dual-axis motor 210 drives the first screw 209 with opposite thread directions to rotate, which drives the connecting ear 208 to slide the sliding plate 205, precisely adjusting the size of the ventilation gap and avoiding unnecessary ventilation. In the fan mechanism, the first drive motor 215 drives the second screw 214 to rotate, causing the displacement mounting plate 211 to move back and forth along the ventilation gap direction under the guidance of the guide slide 213, expanding the ventilation range. The four fan blades 220 on the displacement mounting plate 211 are driven synchronously by the second drive motor 226 through bevel gear and gear transmission to generate airflow. The forward and reverse rotation of the second drive motor 226 can change the airflow direction to meet different ventilation needs. The entire system thus realizes the automatic and precise adjustment of ventilation inside the container.

[0036] It should be noted that the specific models and specifications of the dual-axis motor 210, the first drive motor 215, the second drive motor 226, and the sensor module need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0037] The power supply and operating principles of the dual-axis motor 210, the first drive motor 215, the second drive motor 226, and the sensor module are clear to those skilled in the art and will not be described in detail here.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
