Description

Technical Field

[0001] The utility model relates to the technical field of refrigerated truck manufacturing, in particular to an internal heat preservation structure of a refrigerated truck. Background Art

[0002] In the field of urban short-distance logistics, electric trucks are driven by electricity, so the cost of electricity they consume is much lower than that of fuel trucks. When battery storage technology is improved, the advantages of electric trucks begin to slowly emerge. Refrigerated trucks are a type of logistics vehicle. Because they need to maintain a certain low temperature in the box, they need to consume more electricity. The need for insulation of the box requires that the refrigerated truck compartment cannot have the same design requirements as fuel trucks. The capacity of the battery is limited, so the fuel refrigerated truck compartment cannot be simply transplanted to the electric refrigerated truck compartment. The existing refrigerated truck compartments usually have poor insulation effects and internal ventilation. When driven by batteries, the battery power supply pressure is large, and the short-distance logistics field requires frequent transportation of objects in the compartment. Therefore, there is an urgent need for an internal insulation structure for refrigerated truck compartments with good insulation effects and long service life. Utility Model Content

[0003] The purpose of the utility model is to provide an internal heat preservation structure of a refrigerated truck to solve the problems existing in the above-mentioned prior art.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] The top of the compartment is fixedly provided with a plurality of isolation devices at equal intervals along the length direction of the compartment, the isolation devices comprising a transverse plate, an isolation plate, an air exchange valve, an air exchange pipe, a reel and a drum, the transverse plate is fixedly mounted on the bottom of the isolation plate, the top of the isolation plate is fixedly connected to the inner top of the compartment, bearing seats are provided at both ends of the reel, the bearing seats are fixedly mounted on one side of the isolation plate, and the reel is arranged horizontally, the reel is sleeved on the reel, a drive motor is provided on one side of the transverse plate, the drive motor is connected to the reel through a coupling, an insulation curtain is wound on the reel, a through hole is provided in the middle position of the top of the transverse plate, the through hole is used to avoid the winding path of the insulation curtain, a plurality of through holes symmetrical about the avoidance hole are provided on the top of the transverse plate, an air vent is provided on one side of the isolation plate, and the air exchange valve is fixedly mounted in the air vent.

[0006] By adopting the above technical solution, the drums of multiple isolation devices rotate in different directions driven by the reels, which can make the thermal insulation curtain wrapped on the drums roll up or down. When the thermal insulation curtain is unrolled, the multiple isolation devices divide the interior of the car into multiple unconnected chambers, and at this time, air interaction can be achieved between two adjacent chambers through the through holes on the horizontal plate and the air holes and ventilation valves on the isolation plate, thereby realizing heat exchange between two adjacent spaces. However, when the ventilation valve is closed, the air exchange efficiency drops sharply. By placing the goods inside the car, some spaces do not have much air circulation with the outside world when opening and closing the doors to transport goods, thereby achieving insulation of some areas inside the car and reducing energy consumption during the transportation of goods. Moreover, because the thermal insulation curtain can be rolled up, it does not affect the transportation of goods after rolling up.

[0007] In a further embodiment, a counterweight is provided on the thermal insulation curtain, and the interior of the thermal insulation curtain is filled with thermal insulation cotton.

[0008] In a further embodiment, the transverse plates of two adjacent isolation devices fit together, and the plurality of transverse plates are used to separate the interior of the carriage into two upper and lower chambers that are not connected to each other.

[0009] In a further embodiment, a thermal insulation board is bonded to the bottom of the horizontal board, and the thermal insulation board is made of sponge material.

[0010] In a further embodiment, a cable trough is provided on the top of the horizontal plate, a cable is provided in the cable trough, one end of the cable is electrically connected to the drive motor and the ventilation valve, a control panel is provided on the outside of the car, and the other end of the cable is electrically connected to the control panel.

[0011] In a further embodiment, a heat-insulating cover is provided on the outside of the drive motor, and a temperature sensor is provided on the outside of the heat-insulating cover.

[0012] In summary, the present invention has the following beneficial effects:

[0013] 1. The drums of multiple isolation devices rotate in different directions driven by the reels, so that the thermal insulation curtain wrapped on the drums can be rolled up or unrolled. When the thermal insulation curtain is unrolled, the multiple isolation devices divide the interior of the car into multiple unconnected chambers, and at this time, air interaction can be achieved between two adjacent chambers through the through holes on the horizontal plate and the air holes and ventilation valves on the isolation plate, thereby realizing heat exchange between two adjacent spaces. However, when the ventilation valve is closed, the air exchange efficiency drops sharply. By placing the goods inside the car, some spaces do not have much air circulation with the outside world when opening and closing the door to transport the goods, thereby achieving insulation of some areas inside the car and reducing energy consumption in the process of transporting the goods. And because the thermal insulation curtain can be rolled up, it does not affect the transportation of the goods after rolling up. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-2As shown, an internal insulation structure of a refrigerated truck includes a compartment 1, and a plurality of isolation devices 2 are arranged at equal intervals on the inner top of the compartment 1 along the length direction of the compartment 1. The isolation device 2 includes a transverse plate 21, an isolation plate 22, a ventilation valve 23, a ventilation pipe 24, a reel 25 and a reel 26.

Both ends of the reel 25 are provided with bearing seats 3, and the bearing seats 3 are fixedly mounted on one side of the isolation plate 22, and The reel 25 is arranged horizontally, and the reel 26 is sleeved on the reel 25. A drive motor 4 is provided on one side of the horizontal plate 21, and the drive motor 4 is connected to the reel 25 through a coupling. A thermal insulation curtain is wound on the reel 26. A through hole is provided in the middle of the top of the horizontal plate 21. The through hole is used to avoid the winding path of the thermal insulation curtain.

A ventilation hole is provided on one side of the isolation plate 22, and the ventilation valve 23 is fixedly installed in the ventilation hole.

[0021] like Figure 1-2 As shown, a counterweight is provided on the thermal insulation curtain, and the interior of the thermal insulation curtain is filled with thermal insulation cotton. The horizontal plates 21 of the adjacent isolation devices 2 are fitted together, and the multiple horizontal plates 21 are used to divide the interior of the car 1 into two upper and lower non-connected chambers. An insulation board is bonded to the bottom of the horizontal plate 21, and the insulation board is made of sponge.

[0022] Specific implementation process: The drums of multiple isolation devices rotate in different directions driven by the reels, so that the thermal insulation curtain wrapped on the drums can be rolled up or unrolled.

And because the thermal insulation curtain can be rolled up, it will not affect the transportation of goods after rolling up.
