Description

Technical Field

[0001] This utility model relates to the field of container transportation technology, and in particular to a refrigerated container. Background Technology

[0002] Refrigerated containers are special containers designed for transporting goods that need to be kept at low temperatures, such as fresh fruits and vegetables, meat, aquatic products, vaccines and medicines. Refrigerated containers play a vital role in the global cold chain logistics system, providing a stable low-temperature environment for goods during long-distance transportation, ensuring that the quality of goods is not affected and reducing cargo damage.

[0003] The existing refrigerated container has the following shortcomings:

[0004] Traditional refrigerated containers rely heavily on external power sources or diesel generators to power their refrigeration equipment, resulting in high energy consumption and transportation costs. Furthermore, in remote areas or scenarios without external power sources, the stability of the power supply is difficult to guarantee. At the same time, during long-term use, the dust filters at the exhaust vents of the air conditioning fans in refrigerated containers are easily clogged with dust and impurities, leading to poor ventilation, reduced air conditioning heat dissipation, and consequently, reduced efficiency of the refrigeration equipment. This results in unstable internal temperatures, increasing energy consumption and potentially causing cargo to spoil due to abnormal temperatures. Utility Model Content

[0005] This invention proposes a refrigerated container that achieves energy self-sufficiency and reduces energy consumption by incorporating photovoltaic modules, and ensures heat dissipation efficiency by combining a multi-stage dust removal structure with an exhaust fan, thereby improving the quality of cargo storage and transportation reliability, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a refrigerated container, comprising a container body, wherein a photovoltaic module is fixedly installed on the top right side of the container body, and an air conditioning exhaust fan is fixedly installed on the top left side of the container body.

[0007] The photovoltaic module includes an inverted V-shaped photovoltaic panel, which is fixedly installed on the top right side of the container body. A top cover is fixedly connected to the top of the inverted V-shaped photovoltaic panel, and a first motor is fixedly connected to the left side of the top cover. The output shaft of the first motor passes through the inside of the top cover and is fixedly connected to a transmission screw. An inverted V-shaped sliding plate is threadedly connected to the outer surface of the transmission screw. The lower surface of the inverted V-shaped sliding plate is slidably connected to the upper surface of the inverted V-shaped photovoltaic panel. Cleaning brushes are fixedly connected to both the front and rear sides of the lower surface of the inverted V-shaped sliding plate.

[0008] Preferably, the air conditioner exhaust fan has two exhaust holes on both the front and rear sides, and a dustproof net is fixedly connected to the inner wall of the exhaust hole on the side close to the outer surface of the air conditioner exhaust fan.

[0009] Preferably, a cross bracket is fixedly connected to the inner surface of the exhaust hole, a second motor is fixedly connected to the middle of the cross bracket, a rotating column is fixedly connected to the output shaft of the second motor, and an exhaust fan is fixedly connected to the outer surface of the rotating column near the second motor.

[0010] Preferably, the end of the rotating column away from the second motor extends through to the outer surface of the dustproof net and is fixedly connected to a rotating scraper, which is rotatably connected to the outer surface of the dustproof net.

[0011] Preferably, the rotating column has a connecting groove that runs through the left and right sides in the middle, and a sliding striking plate that runs through the left and right sides is slidably connected inside the connecting groove. The sliding striking plate is set inside the dustproof net, and protrusions are fixedly connected to both the upper and lower sides of the inner surface of the dustproof net.

[0012] Preferably, a tensioning spring is fixedly connected to the side of the sliding striking plate away from the dustproof net, and the end of the tensioning spring away from the sliding striking plate is fixedly connected to the inner wall of the connecting groove.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. In this utility model, through the cooperation of the inverted V-shaped photovoltaic panel, the first motor, the transmission screw, the inverted V-shaped sliding plate, and the cleaning brush, the inverted V-shaped photovoltaic panel converts solar energy into electrical energy to power the refrigeration equipment and other electrical components of the refrigerated container, greatly saving energy consumption. When dust adheres to the surface of the inverted V-shaped photovoltaic panel, the first motor drives the transmission screw to rotate, and the threaded transmission causes the inverted V-shaped sliding plate to slide along the surface of the photovoltaic panel, thereby driving the cleaning brush to clean the surface of the photovoltaic panel, ensuring the light-receiving area and photoelectric conversion efficiency of the photovoltaic panel, ensuring stable power supply, reducing dependence on external power sources, and reducing transportation costs.

[0015] 2. In this utility model, through the cooperation of the second motor, rotating column, exhaust fan, rotating scraper, sliding striking plate, protrusion, and tightening spring, the second motor drives the rotating column to rotate, enabling the exhaust fan to exhaust air and ensure the cooling of the air conditioner. At the same time, the rotating scraper rotates synchronously with the rotating column to scrape and clean the dust and impurities attached to the outer surface of the dustproof net. The sliding striking plate slides in the connecting groove of the rotating column. When it passes the protrusion on the inner surface of the dustproof net, the protrusion pushes the sliding striking plate to compress the tightening spring and slide away from the dustproof net. After leaving the protrusion, the tightening spring resets and pushes the sliding striking plate to quickly rebound and strike the dustproof net, shaking off the dust and impurities in the gaps of the dustproof net. The multiple cleaning structures work together to effectively prevent dust and impurities from clogging the dustproof net, ensuring the exhaust efficiency of the air conditioner exhaust fan, maintaining the stable operation of the refrigeration equipment, ensuring a constant temperature inside the box, and improving the safety of goods storage.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution: including a container body 1, a photovoltaic module 2 is fixedly installed on the top right side of the container body 1, and an air conditioner exhaust fan 3 is fixedly installed on the top left side of the container body 1. The photovoltaic module 2 includes an inverted V-shaped photovoltaic panel 21, which is fixedly installed on the top right side of the container body 1. A top cover 22 is fixedly connected to the top of the inverted V-shaped photovoltaic panel 21. A first motor 23 is fixedly connected to the left side of the top cover 22. The output shaft of the first motor 23 passes through the inner side of the top cover 22 and is fixedly connected to a transmission screw 24. An inverted V-shaped sliding plate 25 is threadedly connected to the outer surface of the transmission screw 24. The lower surface of the inverted V-shaped sliding plate 25 is slidably connected to the upper surface of the inverted V-shaped photovoltaic panel 21. Cleaning brushes 26 are fixedly connected to both the front and rear sides of the lower surface of the inverted V-shaped sliding plate 25.

[0024] The overall effect of Embodiment 1 is as follows: Under illumination, the inverted V-shaped photovoltaic panel 21 converts solar energy into electrical energy, which is stored or directly supplied to electrical components such as refrigeration equipment and lighting equipment inside the refrigerated container. This effectively reduces dependence on external power sources, reduces energy consumption and transportation costs. When dust accumulates on the surface of the inverted V-shaped photovoltaic panel 21, the first motor 23 is started. The first motor 23 drives the transmission screw 24 to rotate. Since the inverted V-shaped sliding plate 25 is threadedly connected to the transmission screw 24, under the action of the threaded transmission, the inverted V-shaped sliding plate 25 slides up and down along the surface of the inverted V-shaped photovoltaic panel 21. At the same time, it drives the cleaning brush 26 fixed on its lower surface to move synchronously. The cleaning brush 26 can clean the dust, leaves and other impurities on the surface of the photovoltaic panel, ensuring the light-receiving area and photoelectric conversion efficiency of the inverted V-shaped photovoltaic panel 21, ensuring stable power supply, and ensuring that the refrigerated container always has a reliable power source to maintain the operation of the refrigeration system during transportation.

[0025] Example 2: Figure 3 and Figure 4 As shown, this utility model provides a technical solution: Two exhaust holes 31 are opened on both the front and rear sides of the air conditioner exhaust fan 3. A dustproof net 32 ​​is fixedly connected to the inner wall of the exhaust hole 31 near the outer surface of the air conditioner exhaust fan 3. A cross bracket 33 is fixedly connected to the inner surface of the exhaust hole 31. A second motor 34 is fixedly connected to the middle of the cross bracket 33. A rotating column 35 is fixedly connected to the output shaft of the second motor 34. An exhaust fan 36 is fixedly connected to the outer surface of the rotating column 35 near the second motor 34. The end of the rotating column 35 away from the second motor 34 extends through the outer surface of the dustproof net 32. A rotating scraper 37 is fixedly connected to the outer surface of the dustproof net 32. The rotating scraper 37 is rotatably connected to the outer surface of the dustproof net 32. A connecting groove 38 that runs through the left and right is opened in the middle of the rotating column 35. A sliding striking plate 39 that runs through the left and right is slidably connected inside the connecting groove 38. The sliding striking plate 39 is set on the inner side of the dustproof net 32. Protrusions 311 are fixedly connected to both the upper and lower sides of the inner surface of the dustproof net 32. A tightening spring 310 is fixedly connected to the side of the sliding striking plate 39 away from the dustproof net 32. The end of the tightening spring 310 away from the sliding striking plate 39 is fixedly connected to the inner wall of the connecting groove 38.

[0026] The overall effect achieved by embodiment 2 is as follows: The second motor 34 is started, which drives the rotating column 35 to rotate. The rotating column 35 drives the exhaust fan 36 to rotate. The airflow generated by the exhaust fan 36 discharges the heat generated during the operation of the air conditioner through the exhaust hole 31, ensuring the air conditioner's heat dissipation. Simultaneously, as the rotating column 35 rotates, the rotating scraper 37 fixed at its end rotates synchronously with it. The rotating scraper 37 can scrape and clean dust, lint, and other impurities adhering to the outer surface of the dustproof net 32, preventing impurities from accumulating on the outer surface of the dustproof net 32. Furthermore, during the rotation of the rotating column 35, the sliding striking plate 39 slides within the connecting groove 38. When the sliding striking plate... When plate 39 passes the protrusion 311 on the inner surface of dustproof net 32, the protrusion 311 pushes the sliding striking plate 39 to move away from the dustproof net 32, compressing the top spring 310. When the sliding striking plate 39 leaves the protrusion 311, the top spring 310 returns to its original position, pushing the sliding striking plate 39 to quickly rebound and strike the dustproof net 32, shaking off the dust and impurities in the gaps of the dustproof net 32. Through the scraping of the rotating scraper 37 and the striking of the sliding striking plate 39, the multiple cleaning structures work together to effectively prevent dust and impurities from clogging the dustproof net 32, ensure the exhaust efficiency of the air conditioner exhaust fan 3, maintain the stable operation of the refrigeration equipment, ensure a constant temperature inside the box, and provide a good storage environment for the goods.

[0027] The working principle of the entire equipment is as follows: During transportation, the refrigerated container first relies on the inverted V-shaped photovoltaic panels 21 to convert solar energy into electrical energy, which powers the refrigeration equipment, the first motor 23, the second motor 34, and other electrical components inside the container. After the refrigeration equipment starts, it cools the inside of the container to maintain the low-temperature environment required for the goods. At the same time, the air conditioning exhaust fan 3 starts working, and the second motor 34 drives the rotating column 35 to rotate, causing the exhaust fan 36 to rotate and expel the heat generated by the air conditioning operation. During the operation of the photovoltaic modules 2, the first motor 23 starts in a timely manner according to the dust accumulation on the surface of the photovoltaic panels, driving the transmission screw 24 to rotate, which drives the inverted V-shaped sliding plate 25 and the cleaning brush 26 to clean the inverted V-shaped surface. Dust on the surface of the photovoltaic panel 21 is removed to ensure power generation efficiency. When the air conditioner exhaust fan 3 is running, the rotating column 35 not only drives the exhaust fan 36 to exhaust air, but also causes the rotating scraper 37 to clean the outer surface of the dustproof net 32. At the same time, the sliding tapping plate 39, under the action of the protrusion 311 and the tightening spring 310, periodically taps the dustproof net 32 ​​to remove dust and impurities from the gaps in the dustproof net 32, ensuring smooth ventilation. Through the coordinated work of power supply and automatic dust removal of the photovoltaic module 2, heat dissipation of the air conditioner exhaust fan 3, and multiple dust removal structures, this refrigerated container achieves energy self-sufficiency and efficient heat dissipation, ensuring stable internal temperature, providing a reliable low-temperature transportation environment for goods, and improving the storage quality and transportation reliability of goods.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
