Technical Field

The utility model relates to an environmental protection equipment technical field specifically relates to a sanitation car.

Background

At present, a sanitation vehicle (particularly a washing and sweeping vehicle) used for cleaning urban roads can continuously recover sewage in the operation process, so that the sewage level in a dustbin can continuously rise, and when the sewage level reaches the limit height, the garbage can needs to be transferred to discharge sewage. Because the circumstances such as turn, acceleration or deceleration can inevitably appear in the way of transition, at this moment, the sewage in the dustbin flows backward easily under the effect of inertial force and gets into the suction tube and then spill subaerial, causes secondary pollution. In order to solve the problem, in the related art, a circle of baffle is usually added on a suction tube of the dustbin to prevent sewage from flowing backwards, but the action of the baffle is very limited, only when the sewage vibrates for a very small time, a small amount of sewage can be prevented from flowing backwards into the suction tube, and the problem cannot be fundamentally solved. In other solutions, a flap mechanism is usually added to the suction canister of the garbage can to block the suction canister, but its driving device (such as a cylinder, etc.) is located in the garbage can and is easily polluted and corroded by the dirt in the garbage can, such as sand, stone and sewage, and can be damaged and failed quickly.

The embodiment of the disclosure provides a sanitation vehicle, which comprises a sewage tank 20, a power bin 40 and a suction tube assembly 10, wherein the power bin 40 is a bin for placing power components such as an auxiliary engine, and the suction tube assembly 10 is mainly applied to the sanitation vehicle to perform road cleaning operation. As shown in fig. 1 and 2, the suction cylinder assembly 10 includes a suction cylinder 11 for sucking dirt into the waste water tank 20, the suction cylinder 11 includes a suction port 111 located outside the waste water tank 20 and a discharge port 112 located inside the waste water tank 20, when the sanitation vehicle performs a road sweeping operation, water is sprayed to a road to suppress dust and wash, the suction port 111 is close to the road, and a negative pressure is formed in the waste water tank 20 to allow various dirt such as garbage, gravel and sewage on the road surface to enter the waste water tank 20 from the suction port 111 at a high speed. The suction cylinder assembly 10 of the disclosed embodiment further includes a cover 12, a link mechanism 13 and an actuating member 14, the cover 12 is movably disposed at the discharge port 112, the actuating member 14 is configured to be disposed in the power bin 40, one end of the link mechanism 13 is connected to the actuating member 14, the other end of the link mechanism 13 passes through the sidewall of the waste water tank 20 and is connected to the cover 12, and the actuating member 14 actuates the link mechanism 13 to move so as to open or close the discharge port 112 with the cover 12.

According to the above structure, during the road sweeping operation of the sanitation vehicle, the actuating member 14 drives the link mechanism 13 to open the discharge port 112 of the cap 12, so that the dirt drawn from the suction port 111 can be discharged from the discharge port 112 into the dirty water tank 20. When the liquid level in the waste water tank 20 reaches the limit position, the actuating member 14 drives the link mechanism 13 to drive the sealing cover 12 to close the discharge port 112, so as to prevent the liquid in the waste water tank 20 from recharging to the suction tube 11 due to inertial shaking.

Through the technical scheme, in the embodiment of the disclosure, the suction tube assembly 10 of the sanitation truck can selectively open or close the discharge port 112 by arranging the sealing cover 12, i.e. the discharge port 112 is opened in the suction cleaning operation, the suction tube 11 is kept smooth, and the discharge port 112 is closed in the transfer operation, so that the suction tube 11 is prevented from being refilled with liquid in the sewage tank 20, the secondary pollution to the road is avoided, and the cleaning capability of the sanitation truck is improved. In addition, the actuating element 14 of the suction cylinder assembly 10 is arranged in the power bin 40, so that the actuating element 14 can be prevented from being corroded and collided by dirt in the sewage tank 20, and the reliability and the service life of the actuating element 14 are improved. Moreover, the actuating element 14 and the sealing cover 12 transmit power through the link mechanism 13, the structure is simple, the link mechanism 13 can realize complex spatial movement, the reliability is high, the link mechanism 13 can also realize remote operation control, and the installation flexibility of the actuating element 14 and the suction tube 11 is improved.

In one embodiment of the present disclosure, as shown in fig. 1 and 2, the link mechanism 13 includes a rocker 131 and a slide rod 132, the slide rod 132 is disposed through the sidewall of the waste water tank 20 in an axially slidable manner, and has a first end located in the power compartment 40 and a second end located in the waste water tank 20, the first end is connected to the actuator 14, the second end is hinged to one end of the rocker 131 around a first rotation axis, the other end of the rocker 131 is hinged to the cover 12 around a second rotation axis, and the first rotation axis and the second rotation axis are arranged in parallel. When the actuator 14 drives the sliding rod 132 to move axially, the rocker 131 is driven to move spatially, thereby opening or closing the discharge opening 112 of the suction cup 11 through the cover 12. It can be seen that the control of the cover 12 is achieved by only two levers, the structure is very simple, and the length of the sliding rod 132 and the rocker 131 can be designed according to the actual situation without limiting the distance between the covers 12 of the actuating element 14.
