The invention is characterized in that the left and right rear water tanks are provided with balance structures at the sides, the balance structures can adjust the rotation angle and the extension length along with the overturning of the water tanks, so that the two rear water tanks are balanced, and the phenomenon of side turning or shaking is not easy to occur even if a small weight deviation occurs.
After the rear water tank is fully loaded, the load of the rear water tank is large, and the pressure of the fully loaded garbage on the whole rear frame and the rear wheel is very large, so that the rear axle is easy to damage, in this way, the invention proposes that the top of the rear water tank is provided with a rivet pulling structure which can be directly extended and fixed to the front end of the frame, under the condition that the rear water tank is fully loaded, the rotating motor of the rivet pulling structure can pull the rivet pulling frame through the steel wire rope through the winch, so that partial weight of the fully loaded rear water tank can be dispersed to the front end position of the frame, and the tensile force provided by the rotating motor can be reduced along with the use of water in the rear water tank, and the overstretched tension is avoided to excessively damage the steel wire rope and the rotating motor.

In the same way as the prior art, the rear water tank 10 of the present invention needs to be lifted along with the dustbin, and although the inclined acting force of the rear water tank 10 can be balanced and shared greatly by the above-mentioned structure, in order to completely ensure the balance effect of the left and right rear water tanks 10, the outer sides of the rear water tanks 10 of the present embodiment are all provided with a balancing structure 1 connected to the frame of the washing and sweeping vehicle, the balancing structure 1 includes a first hinge 101 disposed on the outer side wall of the rear water tank 10, a second hinge 102 mounted on the frame of the washing and sweeping vehicle, and a hydraulic push rod 103 connected between the first hinge 101 and the second hinge 102, the balancing structure 1 can adjust the rotation angle and the extension length along with the overturning of the water tanks, so as to balance the two rear water tanks 10, and even if some weight deviation occurs, the phenomenon of rollover or shaking is not easy to occur, and the corresponding configuration of the hydraulic push rod 103 can be selected along with the specific bearing weight of the rear water tank 10.
After the rear water tank 10 is fully loaded, the load of the rear water tank 10 is large, and the pressure on the whole rear frame and the rear wheels is very high due to the fact that the fully loaded garbage is additionally loaded, so that the rear axle is easy to damage, in this embodiment, at least two groups of rivet structures 2 are arranged at the top of the rear water tank 10, each rivet structure 2 comprises a rivet frame 201 locked at the top of the rear water tank 10, a wire rope 202 locked on the rivet frame 201, a winch 203 welded at the front end of the frame of the washing and sweeping vehicle, a rotating motor 204 inserted on the winch 203, the rotating motor 204 is electrically connected with the first water level sensor 11 and the second water level sensor 12, the rivet structures 2 can be directly extended and fixed to the front end position of the frame, the rotating motor 204 of the rivet structures 2 can pull the rivet frame 201 through the wire rope 202 through the winch 203 under the condition that the rear water tank 10 is fully loaded, the full-load rear water tank 10 can be dispersed to the front end of the frame, and the tension provided by the rotating motor 204 is reduced along with the water in the rear water tank 10, so as to avoid excessively damaging the wire rope 202 and the rotating motor 204 due to the excessively tight tension, and the tension provided by the wire rope 202 is not always unchanged during the actual use, for example, when the rear water tank 10 and the dustbin are in a full-load state, the pressure born by the whole rear wheel and the rear axle system is the largest, and the balance weight of the whole vehicle is mostly concentrated at the rear end, so that the running or working process of the whole vehicle is relatively unsafe, the embodiment electrically connects the rotating motor 204 with the first water level sensor 11 and the second water level sensor 12, and when the second water level sensor 12 detects the water level, the rotating motor 204 is in full-load operation, that is, a part of the force of the rear water tank 10 is dispersed to the front end of the frame to promote the front-rear balance to the greatest extent, and when the second water level sensor 12 senses no water, the water level of the rear water tank 10 gradually drops when the water is gradually used, the pressure on the rear wheel and the rear axle system gradually decreases, and the power of the rotating motor 204 can be gradually reduced at this time for the life of the wire rope 202 and the rotating motor 204, for example, in a periodically attenuated manner, the proportion of 5% power is reduced in 30s, the scattered power of front end diminishes, and until first level sensor 11 senses water, then indicate that the water of back water tank 10 is about to use completely at this moment, then can be relieved and draw the balanced power that rivets structure 2 applyed, let frame rear end self come bearing dustbin and back water tank 10, let draw and rivet structure 2 can change self service condition along with the change of bearing, can reach balanced purpose, can let self life reach the longest again.
In practice, the rivet structure 2 is designed to not only play a role in balancing the front and rear frames, but also produce a linkage effect with the balance structure 1, that is, the balance structure 1 can provide support at both ends when the dustbin and the rear water tank 10 are inclined, and the rivet structure 2 provides a fixed supporting force in the middle, so that the two balance structures 1 and the rivet structure 2 form a delta-shaped arrangement, and balance the rear water tank 10.
