Description

Technical Field

[0001] This utility model relates generally to the technical field of cold storage container structures, and more specifically to a cold storage container. Background Technology

[0002] With the widespread application of photovoltaic power generation technology due to the near-infinite availability of sunlight, containers equipped with solar power systems have been used in many applications. Currently, the following problems exist: 1) Traditional containers (such as explosion-proof containers, refrigerated containers, and truck-mounted refrigerated containers) mostly rely on external power sources or fuel generators for power supply, which have drawbacks such as high energy consumption, high pollution, and dependence on external energy supply. 2) Some containers have attempted to integrate solar panels, but the solar support brackets are mostly at fixed angles and cannot be flexibly adjusted according to the sunlight angle in different regions, resulting in low solar energy utilization. In particular, the solar panels on the sides and top are prone to shading or insufficient sunlight due to mismatched angles.

[0003] 3) Some adjustable brackets are designed for a single position, such as the top or side, and the adjustment method is complicated, the adjustment angle range is limited, the cost is high, and they cannot balance the portability of the container and the high efficiency of solar panel absorption.

[0004] 4) Existing adjustment angles are mostly limited to within 30°, which cannot adapt to the differences in solar altitude angles at different latitudes in the Northern and Southern Hemispheres.

[0005] In summary, existing technologies cannot simultaneously achieve coordinated adjustment of side and top solar panels, and the adjustment range is limited and the operation is complex, resulting in a solar energy utilization rate of less than 30%, which is difficult to meet customer needs.

Figure 8In this configuration, the plane containing the first photovoltaic component 121 forms a 45° angle with the plane containing the top plate 111; the plane containing one second photovoltaic component 131 forms a 45° angle with the plane containing the side plate 113, and the plane containing the other second photovoltaic component 131 forms a 135° angle with the plane containing the side plate 113. It should be noted that... Figure 8 In this configuration, the left end of the first photovoltaic component 121 is connected to the housing 110; and the angle between the plane of the second photovoltaic component 131 on the left and the plane of the side plate 113 is 45°, while the angle between the plane of the second photovoltaic component 131 on the right and the plane of the side plate 113 is 135°.

Specifically, the first support 122 is disposed on the outside of the container body 110. The first support 122 is pivotally adjustable to the top of the container body 110 about a first axis extending along the length direction DL of the container body 110. A first photovoltaic component 121 is connected to the first support 122 and can pivot with the first support 122. The second support 132 is disposed on the outside of the container body 110.

[0047] The following explains the connection and position adjustment of photovoltaic components to the housing.

[0048] Please see now Figures 10 to 13 The container body 110 is externally connected to an assembly member 160. The assembly member 160 is, for example, constructed as a bent piece with an L-shaped (or approximately L-shaped) cross-section. A first fixing member 161 is connected to the top of the assembly member 160, and the first fixing member 161 has an assembly hole 165 extending through the thickness of the first fixing member 161. The first fixing members 161 are arranged in pairs, with the two pairs spaced DL apart along the length direction of the cold storage container 100. The two pairs of first fixing members 161 are used for connection to a first support 122 (detachable). A second fixing member 164 (see...) is provided on the side of the first fixing member 161. Figure 11 and Figure 12 The second fixing member 164 is constructed as a cylindrical structure (see...).

[0049] Please see now Figure 14 and Figure 15 The first guide rail 115 and the second guide rail 116 are both configured to be detachably connected to the housing 110. The first guide rail 115 is connected to the top plate 111 of the housing 110, and the second guide rail 116 is connected via mounting member 114 (see...). Figure 2A first sliding member 145 is slidably connected to a first guide rail 115, and a second sliding member 155 is slidably connected to a second guide rail 116. Both the first and second sliding members 145 are provided with locking members 117. The locking member 117 located at the first sliding member 145 is pivotally connected to the first sliding member 145 via a second pivot shaft 118. The locking member 117 located at the second sliding member 155 is pivotally connected to the second sliding member 155 via a second pivot shaft 118. The locking member 117 includes a locking hook 119. Both the first and second guide rails 115 and 116 are provided with slots suitable for the locking hook 119. That is, the locking hook 119 and the corresponding slots constitute the aforementioned locking structure. When the locking hook 119 is connected to the slot, the locking structure is in a locked state; when the locking member 117 is flipped so that the locking hook 119 is separated from the slot, the locking structure is in an unlocked state. To improve the accuracy of adjustment, scale lines are provided on the first guide rail 115 and the second guide rail 116; correspondingly, multiple slots are also provided for connection with the locking hook 119.

[0050] According to this utility model, the cold storage container is equipped with adjustable photovoltaic components on the sides and top of the container body, which enables the photovoltaic components to absorb heat efficiently under different light conditions, reducing the cold storage container's dependence on traditional energy sources, while taking into account the convenience of adjustment and the overall functionality of the cold storage container.

[0051] The interior of the housing 110 is equipped with a variable frequency refrigeration system, and the load-bearing capacity of the first support 122 and the second support 132 is greater than or equal to 50 kg / m. 2 The arrangement of the first support 122 and the second support 132 does not affect the sealing and insulation performance of the cold storage container. Specifically, the first support 122 avoids corner fittings and other components, and the second support 132 avoids door handles, locks, and other components of the container body 110.

[0052] When the power generation of the photovoltaic module is greater than or equal to the power consumption of the load, the excess power is used to charge the energy storage device. When the energy storage device is fully charged, the excess power is transmitted to the grid. When the power generation of the photovoltaic module is less than the power consumption of the load, the energy storage device compensates for the load. When the percentage of the energy storage device's power is less than 15%, the energy storage device stops discharging to protect itself, and the grid compensates for the load's power consumption.
