[0023] Embodiment 1:

[0024] See also Figure 1-4 A refrigeration system for a refrigerated container includes a refrigerated container body 1, a refrigeration device 2 is detachably mounted on one side of the inner wall of the refrigerated container body 1, four limiting slide grooves 3 are symmetrically opened inside the refrigeration device 2 along the center, a hydraulic telescopic rod 4 is detachably mounted on one side inside the limiting slide groove 3, a filter screen 5 is connected to the inside of the refrigeration device 2 through the hydraulic telescopic rod 4, four stable connecting plates 6 are welded to the outer surface of the filter screen 5 in a rectangular array, four safety protection components 7 are detachably mounted on the outer surface of the refrigeration device 2 in a rectangular array, and two exhaust components 8 are detachably mounted on the lower surface of the refrigeration device 2 along the center symmetrically;

[0026] Benefits: The limiting telescopic rod 75 is provided to ensure that the movement trajectory of the release spring 74 does not change when the release spring 74 is working, thereby ensuring that the release spring 74 can operate normally.

[0027] The working process of the utility model is as follows:

[0028] When the refrigerated container refrigeration system is in use, in order to enhance the safety performance of the device, a safety protection component 7 is provided. When the staff accidentally contacts the corners of the refrigeration device 2 when taking or placing goods, the safety protection component 7 arranged at the corners of the refrigeration device 2 will work, and then the safety protection block 71 will transfer the external force received by the contact to the release spring 74 and the limiting telescopic rod 75. When the external force acts on the release spring 74, the release spring 74 will release the external force received according to its own performance, so as to reduce the reaction force received by the staff. In addition, the material of the safety protection block 71 is a rubber component, and the corners are rounded, so it can prevent the staff from being injured, so that there is no safety hazard in the device.

[0029] In the above scheme, when the refrigerated container refrigeration system is in use, in order to improve the refrigeration efficiency of the device, a limit slide groove 3, a hydraulic telescopic rod 4 and a stable connecting plate 6 are provided. When the surface of the filter 5 arranged inside the air outlet is frozen, the hydraulic telescopic rod 4 is started to drive the stable connecting plate 6 to move. Because the filter 5 is connected to the hydraulic telescopic rod 4 through the stable connecting plate 6, the movement of the stable connecting plate 6 can drive the filter 5 to move until the filter 5 is moved out of the interior of the refrigeration device 2, so as to clean the surface of the filter 5. Because the hydraulic telescopic rod 4 has the function of automatic expansion and contraction, the position of the filter 5 can be adjusted to avoid the phenomenon of ice on the surface of the filter 5, which affects the operation of the refrigeration device 2, thereby improving the working efficiency of the device.
