Description

Technical Field

[0001] This invention relates to the technical field of semi-trailer transportation, and more particularly to a mildew-proof and ventilated structure for a box-type semi-trailer. Background Technology

[0002] Box-type semi-trailers are widely used in the transportation of goods that are susceptible to moisture, such as agricultural products, textiles, and electronic components, due to their advantages of strong sealing, large load capacity, and good protection of goods. However, during long-distance transportation, the poor air circulation and humidity accumulation inside the compartment can easily lead to problems such as mold and rot, resulting in cargo loss.

[0003] Most ventilation equipment is electrically driven, which consumes electricity continuously during long-distance transportation. This not only increases operating costs but also poses a risk of insufficient onboard power. The lack of scientific zoning inside the vehicle means that moisture can easily cross-contaminate when different humidity-sensitive goods are mixed together. Furthermore, the partition design makes it difficult to work in coordination with the ventilation system, thus failing to achieve precise ventilation in independent areas. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0016] In view of the problems existing in the above-mentioned anti-mildew ventilation methods for box-type semi-trailers, the present invention is proposed.

[0017] Therefore, the purpose of this invention is to provide a method for preventing mold and ventilation in a box-type semi-trailer, the purpose of which is to achieve: zoned structure and automatic linkage, adaptive assembly, and ventilation and mold prevention.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1 Reference Figures 1-8 This is the first embodiment of the present invention, which provides a method for preventing mold and ventilation in a box-type semi-trailer. Through the mold-proof ventilation structure of the box-type semi-trailer, the effects of ventilation, compartment partitioning and ventilation regulation are achieved.

[0034] According to the characteristics of the goods, the operator activates the cylinder control system. The cylinder outputs power to push the first plate 105 to slide along the slide rail on the top of the inner wall of the carriage frame 101. During the movement of the first plate 105, the partition 107 fixedly connected at the bottom moves synchronously, dividing the internal space of the carriage frame 101 into multiple independent areas. For example, moisture-sensitive agricultural products can be stored separately from dry electronic products. The movable door 106 at the front end of the first plate 105, which penetrates the carriage frame 101, is linked with the partition 107. When the partition 107 stops moving and completes the partitioning, the movable door 106 automatically closes to ensure that each partition is sealed. The first pad 202 and the second pad 203 in the inner cavity of the first plate 105 drive the first ventilation fan 204 on them to move to the top position of the corresponding partition, forming a ventilation layout covering different areas with the second ventilation fan 205 on the second plate 201.

[0035] After the vehicle starts moving, the outside airflow enters the top area of ​​the vehicle frame 101 through the air vent 101e on the right side of the rainproof plate 101d. The airflow impacts the rotating fan 204g on the surface of the telescopic rod 204e and the long rod 204f, causing them to start rotating. The rotational power of the rotating fan 204g is transmitted sequentially to the first movable rod 204c and the second movable rod 204d through the universal joint, which in turn drives the first control panel 204a and the second control panel 204b to rotate. The rotation of the first control panel 204a and the second control panel 204b drives the first ventilation fan 204 and the second ventilation fan 205 to open through the rotating shaft. When the vehicle starts operating, it achieves initial air circulation inside the carriage. As the vehicle speed increases, the rotational force of the rotating fan 204g increases, which increases the torque transmitted to the first control panel 204a and the second control panel 204b. Under pressure, the spring rod 204j in the inner cavity of the control panel moves from the first slot 204h to the second slot 204i, making contact with more of the second push plates 204m. The second push plates 204m push the rectangular plate 204k, causing the overall angle of the control panel to adjust, thereby increasing the speed and air delivery angle of the first ventilation fan 204 and the second ventilation fan 205, achieving an adaptive increase in ventilation intensity.

[0036] When the first ventilation fan 204 and the second ventilation fan 205 are running, they draw the humid air inside the carriage upwards and discharge it through the ventilation opening 101c at the corresponding position on the top of the carriage frame 101. The rainproof plate 101d is set at an angle, and its special airflow guiding structure guides the rainwater to the sides for discharge. At the same time, the orientation and height design of the air vent 101e effectively prevents rainwater, sand and dust and other foreign objects from entering the ventilation opening 101c, ensuring that the ventilation can continue to work stably in severe weather such as rain, snow and sand.

[0037] Example 2 Reference Figure 2 and 3 In the second embodiment of the present invention, a carriage mechanism 100 is provided, through which zone adjustment is realized.

[0038] The carriage mechanism 100 includes a carriage frame 101. An electric door 102 is provided on the left side of the front end of the carriage frame 101, a fixed door 103 is provided on the right side of the front end of the carriage frame 101, and a back door 104 is provided on the right side of the carriage frame 101. A first plate 105 is slidably connected to the top of the inner wall of the carriage frame 101. The first plate is driven by a cylinder. A movable door 106 is fixedly connected to the front end of the first plate 105 through the front end of the carriage frame 101. A partition 107 is fixedly connected to the bottom of the first plate 105. The partition 107 is used for partitioning the interior of the carriage frame 101.

[0039] Specifically, the front end of the first plate 105 passes through the carriage frame 101 and is fixedly connected to the movable door 106. When the first plate 105 moves, the movable door 106 opens and closes synchronously to ensure the sealing of the partition boundary. The partition 107 fixedly connected to the bottom of the first plate 105 moves with the first plate 105 to flexibly partition the internal space of the carriage frame 101. The size and number of partitions can be freely adjusted according to the characteristics of cargo size, humidity sensitivity, etc., effectively avoiding cross-contamination of moisture between different goods and improving the safety of cargo storage.

[0040] Furthermore, the operator controls the electric door 102 to open and the rear door 104 to load and unload goods from the carriage frame 101. Depending on the type of goods, such as moisture-sensitive or dry, the first plate 105 is driven by a cylinder to slide along the top of the carriage, simultaneously moving the bottom partition 107 to adjust the pre-partitioned space inside the carriage. At this time, the movable door 106 at the front of the first plate 105 is activated along with the partition 107 to ensure the partition boundaries during the loading and unloading process.

[0041] Example 3 Reference Figures 4-8 In the third embodiment of the present invention, a ventilation mechanism 200 is provided, which achieves the effects of ventilation and ventilation regulation.

[0042] The ventilation mechanism 200 includes a second plate 201, which is located on the top right side of the inner wall of the carriage frame 101. The inner cavities of the first plate 105 and the second plate 201 are provided with a first pad 202 and a second pad 203. The tops of the first pad 202 and the second pad 203 are movably connected to the first ventilation fan 204 and the second ventilation fan 205 through a rotating shaft.

[0043] The tops of the first ventilation fan 204 and the second ventilation fan 205 are movably connected to the first control panel 204a and the second control panel 204b via a pivot. The tops of the first control panel 204a and the second control panel 204b are movably connected to the first movable rod 204c and the second movable rod 204d via a universal joint. A telescopic rod 204e is fixedly connected to the left side of the first movable rod 204c, and a long rod 204f is fixedly connected to the left side of the second movable rod 204d. A rotating fan 204g is fixedly sleeved on the left side of both the telescopic rod 204e and the long rod 204f. The rotating fan 204g is started by airflow. The inner cavities of the first control panel 204a and the second control panel 204b have a first slot 204h and a second slot 204i. The first slot 204h has two slots. There are four second slots 204i. Spring rods 204j are movably connected to the inner cavities of the first slot 204h and the second slot 204i. The right side of the spring rod 204j passes through the right side of the first control panel 204a. A rectangular plate 204k is fixedly connected to the front end of the spring rod 204j. A first push plate 204l is fixedly connected to the top of the first control panel 204a and the second control panel 204b. There are two first push plates 204l, each fixed to the front end of the rectangular plate 204k at the position corresponding to the first slot 204h. A second push plate 204m is fixedly connected to the top of the first control panel 204a and the second control panel 204b. There are four second push plates 204m, each fixed to the front end of the rectangular plate 204k at the position corresponding to the second slot 204i.

[0044] A first air duct 101a is fixedly connected to the top of the carriage frame 101, and a second air duct 101b is fixedly connected to the top of the first air duct 101a. The first air duct 101a is set on the surface of the telescopic rod 204e, and the second air duct 101b is set on the surface of the long rod 204f. A ventilation opening 101c is provided on the top of the carriage frame 101, corresponding to the positions of the first ventilation fan 204 and the second ventilation fan 205. A rainproof plate 101d is fixedly connected to the top of the carriage frame 101, and an air guide vent 101e is provided on the right side of the rainproof plate 101d.

[0045] Specifically, the spring rod 204j in the first control panel 204a and the second control panel 204b cooperates with the first push plate 204l and the second push plate 204m. When the wind force of the rotating fan 204g increases, the spring rod 204j is pressed and moves, pushing the push plate to adjust the angle of the control panel, thereby changing the speed and direction of the ventilation fan and realizing adaptive adjustment of ventilation intensity.

[0046] Specifically, the rainproof plate 101d covers the ventilation opening 101c, and the right-side air guide 101e is designed to not only block rainwater, sand and dust and other foreign objects from entering the carriage, but also guide natural airflow into the air duct, ensuring that the ventilation system continues to operate stably in severe weather, taking into account both protection and ventilation efficiency.

[0047] Furthermore, after the cylinder stops driving, the first plate 105 and the partition 107 are fixed in position, dividing the interior of the carriage frame 101 into independent areas, realizing physical isolation of different goods and avoiding cross-contamination of moisture. The first ventilation fan 204 on the first plate 105 is positioned synchronously with the partition 107, and corresponds to different zones as the second ventilation fan 205 on the second plate 201.

[0048] Furthermore, when the vehicle is in motion, airflow enters through the air vent 101e of the rainproof plate 101d, driving the rotating fan 204g on the surface of the telescopic rod 204e and the long rod 204f to rotate. The power of the rotating fan 204g is transmitted through the telescopic rod 204e and the long rod 204f to the first movable rod 204c and the second movable rod 204d, and then drives the first control panel 204a and the second control panel 204b to rotate via the universal joint, ultimately driving the first ventilation fan 204 and the second ventilation fan 205 to operate synchronously and start ventilation.

[0049] Furthermore, as the vehicle speed increases, the rotational force of the rotating fan 204g increases, and the torque transmitted through the movable rod is enhanced. At this time, the spring rod 204j in the first control plate 204a and the second control plate 204b is subjected to greater pressure, moving from the first slot 204h to the second slot 204i, contacting more of the second push plates 204m, pushing the rectangular plate 204k to adjust the angle of the control plate, thereby increasing the speed and air delivery angle of the ventilation fan and improving the ventilation effect. When the first ventilation fan 204 and the second ventilation fan 205 are running, the humid air in the carriage is drained out through the vent 101c.

[0050] The remaining structure is the same as that in Example 2.

[0051] Example 4 Reference Figures 1-8 This is the fourth embodiment of the present invention, which differs from the third embodiment in that: this embodiment provides a mildew-proof ventilation structure for a box-type semi-trailer.

[0052] Operators control the electric door 102 to open and the rear door 104 to load and unload goods from the carriage frame 101. Depending on the type of goods, such as moisture-sensitive or dry, the first plate 105 is driven by a cylinder to slide along the top of the carriage, which simultaneously moves the bottom partition 107 to adjust the pre-partitioned space inside the carriage. At this time, the movable door 106 at the front of the first plate 105 is activated along with the partition 107 to ensure the partition boundaries during the loading and unloading process.

[0053] After the cylinder stops driving, the first plate 105 and the partition 107 are fixed in position, dividing the interior of the carriage frame 101 into independent areas, realizing physical isolation of different goods and avoiding cross-contamination of moisture. The first ventilation fan 204 on the first plate 105 is positioned synchronously with the partition 107, and corresponds to different zones as the second ventilation fan 205 on the second plate 201.

[0054] When the vehicle is in motion, airflow enters through the air vent 101e of the rainproof plate 101d, driving the rotating fan 204g on the surface of the telescopic rod 204e and the long rod 204f to rotate. The power of the rotating fan 204g is transmitted through the telescopic rod 204e and the long rod 204f to the first movable rod 204c and the second movable rod 204d, and then drives the first control panel 204a and the second control panel 204b to rotate via the universal joint, ultimately driving the first ventilation fan 204 and the second ventilation fan 205 to operate synchronously and start ventilation.

[0055] As the vehicle speed increases, the rotational force of the rotary fan 204g increases, and the torque transmitted through the movable rod is enhanced. At this time, the spring rod 204j in the first control plate 204a and the second control plate 204b is subjected to greater pressure, moving from the first slot 204h to the second slot 204i, contacting more of the second push plates 204m, pushing the rectangular plate 204k to adjust the angle of the control plate, thereby increasing the speed and air delivery angle of the ventilation fan and improving the ventilation effect. When the first ventilation fan 204 and the second ventilation fan 205 are running, the humid air in the carriage is drained out through the vent 101c.

[0056] The rainproof plate 101d blocks rainwater and sand from entering the ventilation opening 101c, ensuring that the ventilation function is not interrupted in severe weather. At the same time, the air guide 101e directs the airflow and improves the efficiency of wind power utilization. After the vehicle stops, the rotating fan 204g stops rotating as the airflow weakens, and the ventilation fan stops working at the same time.

[0057] In summary, the carriage frame 101 in the carriage mechanism 100 achieves internal space partitioning through the first plate 105 and the partition 107, separating different goods to avoid cross-contamination of moisture. At the same time, the partition 107 cooperates with the ventilation mechanism 200 to form an independent ventilation area, improving the specificity of mildew prevention. The electric door 102, fixed door 103, and back door 104 facilitate the loading and unloading of goods. The first plate 105 is linked to the movable door 106 for automatic opening and closing. The rotating fan 204g is started by the wind power of the vehicle movement, without the need for additional energy, driving the first ventilation fan 204 and the second ventilation fan 205 to operate. At the same time, the position of the first ventilation fan 204 is adjusted by adjusting the position of the partition 107. The first ventilation fan 204 and the second ventilation fan 205 are driven by the wind power of the vehicle movement. When the rotation force of the rotating fan 204g increases, it contacts more of the second push plate 204m through the spring rod 204j, making its ventilation effect better.
