Embodiment 1

[0027] The wheeled surface runoff sampling device is placed on the ground to be sampled, and is connected with the towing vehicle through the towing rod 75 with a cable.

[0028] Place the water cup for sampling in the cup tube 62 of the reservoir 6, put the power supply into the battery pack box 51, turn on the power supply and combine the sampling distance L and the number of sampling bottles M, according to F=L / (π*D / N *M) Set the frequency F on the stepper motor controller 52. And cover cover plate 74, use screw to lock cover plate 74 by left and right cover plate locking frames 71, front and rear cover plate locking frames 72.

[0029] Start the traction vehicle, and the traction wheel type surface runoff sampling device moves forward. The tire 31 on the wheel 3 drives the axle 32 and the driving gear 33 to rotate. The driving gear 33 drives the guide gear 22 on the pedometer 2 to rotate, and the guide gear 22 drives the speed change gear box 21 to rotate through the inp...

Abstract

The invention relates to a wheel type overland runoff sampling device which can be applied to large-scale road overland runoff automation sampling. The wheel type overland runoff sampling device comprises a fluid director, a pedometer, a vehicle wheel, a rotation motor, an electric controller, a memory and a chassis. The wheel type overland runoff sampling device is suitable for urban overland runoff sampling and is used for solving the current situation that usual pumping type and intercept type samplers can not effectively collect overland runoff due to the fact that water level of road overland runoff is low. Meanwhile, the wheel type overland runoff sampling device integrates the wheel type part, the sampler realizes movable sampling, the sampling area is effectively expanded, and the sampling efficiency is improved. A step counting device is designed, a stepping motor control circuit is combined, and overland runoff with various lengths can be classified and collected by the control circuit to realize sampling automation.

Description

technical field [0001] The invention belongs to the technical fields of municipal engineering and environmental protection, and in particular relates to a wheeled surface runoff sampling device. Background technique [0002] With the rapid development of urban construction, the complexity of the underlying surface in the urban area has increased, the emission of atmospheric smoke and dust has increased, and the traffic volume has increased. In the rainwater runoff formed by rainfall, the conditions of production and confluence have changed greatly, mainly containing chemical oxygen demand (COD ), total nitrogen (TN), total phosphorus (TP), suspended solids (SS) and various heavy metals and other pollutants. The amount of initial rainfall is limited, and it is difficult to collect during the ground travel. Moreover, for further research, it is necessary to collect and test the initial rainfall in different areas. [0003] The existing sampling device has the limitations of ...
