Description

Technical Field

[0001] The utility model relates to a new energy vehicle chassis sewer dredging and cleaning vehicle. Background Art

[0002] The new energy vehicle chassis sewer cleaning vehicle has a structure including a new energy vehicle chassis, a water tank and an equipment compartment on the vehicle chassis, a dredging reel connected to the water tank, and a water pump unit in the equipment compartment, which includes a motor and a high-pressure water pump. The working principle is that the high-pressure water pump pumps the water in the water tank into the sewer through the hose of the dredging reel, and uses the jet technology of the nozzle to break up the blockage in the sewer pipe, thereby achieving the dredging task.

[0003] Sewer unclogging and cleaning vehicles usually perform unclogging and cleaning operations in the early morning when residents are usually asleep. The noise generated by the water pump unit during operation is relatively loud, which affects the residents' normal rest to a certain extent. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a new energy vehicle chassis sewer dredging and cleaning vehicle. After the utility model is applied, the noise generated by the water pump unit during the sewer dredging operation can be effectively reduced.

A water tank and an equipment compartment are arranged on the vehicle chassis. The water tank is connected with a dredging reel. A water pump unit is arranged in the equipment compartment. The water pump unit includes a motor and a high-pressure water pump. A sound insulation cover is also arranged in the equipment compartment. The motor and the high-pressure water pump are located in the sound insulation cover. The sound insulation cover is composed of an inner layer of aluminum foil, a middle layer of sound-absorbing cotton and an outer layer of thin steel plate. Sound-absorbing holes are evenly spaced on the sound insulation cover.

[0006] As an improvement of the utility model, the equipment cabin also has a mounting base plate and a mounting flat plate, a seismic isolator is installed between the mounting flat plate and the mounting base plate by bolts, the mounting base plate is fixed to the bottom wall plate in the equipment cabin, the motor and the high-pressure water pump are fixed on the mounting flat plate, and the bottom of the sound insulation cover is fixed to the mounting base plate.

[0007] Furthermore, the seismic isolator has steel plates located at the upper, middle and lower layers, a damping rubber layer is arranged between adjacent steel plates, and bolt mounting holes are opened on the seismic isolator.

[0008] As a further improvement of the utility model, egg-nest-shaped cotton is bonded to the inner side of the wall panel of the equipment cabin.

[0009] As a further improvement of the present invention, the output shaft of the motor and the input shaft of the high-pressure water pump are connected via a straight shaft connector.

[0010] The utility model has the following beneficial technical effects: First, a soundproof cover is arranged in the equipment cabin, and the motor and the high-pressure water pump are located in the soundproof cover, which can effectively reduce the noise propagation to the external environment when the water pump unit is working; second, a seismic isolator is connected between the mounting plate and the mounting base plate, and after the motor and the high-pressure water pump are fixed on the mounting plate, the sound wave vibration propagation to the external environment when the water pump unit is working can be effectively reduced; third, egg-nest-shaped cotton is bonded to the inner side of the wall panel of the equipment cabin, which can further play a sound-absorbing role; fourth, a straight-axis connection is adopted between the output shaft of the motor and the input shaft of the high-pressure water pump, which eliminates the transmission noise generated by the traditional universal joint transmission shaft.
