7. The carriage side-leakage prevention device for the dump semi-trailer according to claim 1, wherein: the top fixed connection of electric telescopic handle (1) is on connecting plate (25), the output fixedly connected with bottom plate (24) of electric telescopic handle (1), a plurality of stainless steel harrow strips (14) of below fixedly connected with of bottom plate (24), electric telescopic handle (1) and driving motor (19) electric connection, a control switch is shared with driving motor (19) in electric telescopic handle (1).

8. The use method of the carriage side leakage preventing device for the dump semi-trailer according to claims 1 to 7, wherein: the method comprises the following steps:

the first step is as follows: the sandy soil is poured into the carriage (18), then a control switch in the vehicle head (17) is turned on, and at the moment, the driving motor (19) and the electric telescopic rod (1) start to work;

the second step is that: when the driving motor (19) rotates, the threaded rod (2) is driven to rotate, the threaded rod (2) is in threaded connection with the fixed block (16), so that the fixed block (16) is driven to move leftwards, meanwhile, the fixed block (16) drives the vertical rod (8) outside the automatic telescopic awning (13) to move leftwards together, and the sliding block (9) at the bottom end of the vertical rod (8) slides towards the tail part of the carriage (18) together under the action of the sliding groove (10);

the third step: in the sliding process, the bottom end of the fixed block (16) is fixedly connected with an electric telescopic rod (1) through a connecting plate (25) to drive the bottom plate (24) to move downwards to the position above sandy soil, at the moment, the stainless steel rake strip (14) starts to move towards the left side under the action of the fixed block (16) to push the raised sandy soil flat, the height of the sandy soil is ensured to be lower than that of the carriage (18), and the external leakage is prevented;

the fourth step: when a limiting block (22) on a vertical plate (8) touches a first limiting switch (20), a control switch in a headstock (17) is closed, an electric telescopic rod (1) drives a bottom plate (24) to move upwards, a driving motor (19) and the electric telescopic rod (1) stop working, and an automatic telescopic tent (13) is in a stretching state at the moment, so that sandy soil in a carriage (18) is protected from being wetted by rainwater in the transportation process, and the sandy soil is prevented from leaking to pollute the environment;

the fifth step: when unloading is needed, a control switch in the vehicle head (17) is opened, at the moment, a driving motor (19) starts to work, the driving motor (19) drives a fixing block (16) to move rightwards under the action of a threaded rod (2) and a sliding rod (26), meanwhile, the fixing block (16) drives a vertical rod (8) outside an automatic telescopic tent (13) to move rightwards, the vertical rod and the sliding block (9) at the bottom end of the vertical rod (8) and the sliding groove (10) slide towards the front end of a carriage (18) together, when a limiting block (22) on the vertical rod (8) touches a second limiting switch (21), the control switch in the vehicle head (17) is closed, the driving motor stops working, at the moment, the automatic telescopic tent (13) is in a compressed state and is located below a sun shield (5), and a sun-proof effect is achieved.
