Detailed Description

The embodiment of the application provides a leak protection device for material transportation, can guarantee under the closing cap state that there is not dregs to spill from the carriage.

In order to solve the problems in the background art, the technical scheme in the embodiment of the application has the following general idea:

example 1:

this embodiment specifically describes the specific structure of the whole device, as shown in fig. 1-5, a leakage-proof device for material transportation comprises two parts, which are respectively: a folding cover component 3 and a telescopic cover component 4;

the folding sealing cover component 3 is arranged above the carriage 1 in a sliding mode in a covering mode, the folding sealing cover component 3 comprises a driving mechanism and a folding cloth main body, the driving mechanism is used for driving the folding cloth main body to expand and sealing an opening above the carriage 1, the whole folding sealing cover component 3 is in a state shown in the figure 1 after being completely expanded, and meanwhile the driving mechanism is used for driving the whole folding cloth main body to expand to achieve protection treatment;

the telescopic hood component 4 is fixedly arranged on the surface of the rear cover 2 of the vehicle arranged at the tail part of the carriage 1, the telescopic hood component 4 comprises a hood body 41 and an inflator 42 arranged on the surface of the hood body 41, the inflator 42 is positioned on the movable track of the folding cloth main body, and the air outlet of the inflator 42 is communicated with the hood body 41;

in some examples, the folding cover assembly 3 comprises a main frame 32 and a plurality of sub-frames 33, and the main frame 32 and the plurality of sub-frames 33 are connected by a tarpaulin 31; the two sides of the carriage 1 are both provided with sliding chutes 7 for the driving mechanism to be arranged;

specifically, the entire drive mechanism is incorporated in the slide groove 7, both ends of the main and sub-frames are inserted into the slide groove 7, and the main frame 32 and the sub-frames 33 have the same shape and size.

In some examples, the driving mechanism comprises a stepping motor 5 and a screw rod 6 assembled on the output end of the stepping motor 5, and the screw rod 6 sequentially penetrates through each sub frame body 33 and is in screw connection with the main frame body 32;

in the driving process, the stepping motor 5 drives the screw rod 6 to rotate, so that the main frame body 32 on the surface of the screw rod 6 moves in the limiting direction of the chute 7, and each auxiliary frame body 33 at the position is driven by the main frame body 32, so that the whole folding cover sealing assembly 3 is unfolded integrally.

In some examples, both sides of the cover 41 in the unfolded state are arc-shaped, and the cover 41 is always located below the folding cover assembly 3;

by adopting the technical scheme:

in the folding closing cap subassembly 3 of design, utilize lead screw 6 among the actuating mechanism, the whole folding closing cap subassembly of the decision that turns to of lead screw 6 is expanded or is closed, lead screw 6 and the cooperation of spout 7 simultaneously to ensure that each framework is linear movement, occupation space is great when being different from the tradition and utilizing the cylinder to adjust, and more space can not be taken in this application, also can guarantee the stability of regulation and control operation simultaneously.

Example 2:

based on embodiment 1, the present embodiment specifically describes a specific structure of the retractable cover assembly, as shown in fig. 3 and 5, the retractable cover assembly 4 is fixedly disposed on the surface of the rear cover 2 disposed at the rear of the vehicle compartment 1, and the retractable cover assembly 4 includes a cover body 41 and an inflator 42 mounted on the surface of the cover body 41, the inflator 42 is located on the moving track of the folding cloth main body, and the air outlet of the inflator 42 is communicated with the cover body 41.
