As shown in fig. 1 and 3, three sets of upright posts 7 on the same side are arranged along the length direction of the disinfection channel 1, two sets of upper spray heads 8 and two sets of lower spray heads 9 are arranged on the same side, the upright post 7 close to the gate is a first set, the upright post 7 in the middle is a second set, the upright post 7 far away from the gate is a third set, the two sets of upper spray heads 8 are respectively connected to the upper ends of the first set and the second set of upright posts 7, and the two sets of lower spray heads 9 are respectively connected to the lower ends and the middle parts of the first set and the;

as shown in fig. 1 and 4, a groove 17 for placing the bottom spray pipe 5 is formed at the bottom end of the disinfection channel 1, a water guide table 18 with a trapezoidal cross section is arranged at the bottom of the groove 17, and drain pipes 19 are arranged on two sides of the bottom end of the water guide table 18; the outer peripheral surfaces of the main pipe 10 and the branch pipes 11 are provided with insulating layers (not shown in the drawings, as they are).

In conclusion, compared with the prior art, the invention avoids the situation that people are mistakenly sprayed and reduces the waste of disinfectant, and has the advantages of high disinfection efficiency and cost saving; through the metal detection device 6, the photoelectric switch 15 and the control cabinet 3, and because the distance between the photoelectric switch 15 and the metal detection device 6 is [1.8,2] m, when a vehicle drives from a gate to the position where the front end of the vehicle is located in the detection range of the photoelectric switch 15, the rear vehicle body of the vehicle is still in the detection range of the metal detection device 6, at the moment, the control cabinet 3 controls the main electromagnetic valve 12 to be opened, and the effect of jointly triggering the spraying mechanism 4 and the bottom spraying pipe 5 to be started is realized; the condition that people are sprayed by mistake due to passing is prevented, and the effects of improving the whole disinfection efficiency and saving the cost are achieved; the control cabinet 3, the bottom spray pipe 5, the main electromagnetic valve 12, the main pipeline 10, the lower spray head 9 and the disinfection water tank 2 are used for automatically and respectively spraying and disinfecting the bottom, two sides and the top of the vehicle, so that the overall disinfection efficiency is further improved; through the branch pipeline 11, the upper spray head 8, the branch electromagnetic valve 13, the control cabinet 3 and the infrared sensor 14, the higher vehicle disinfection efficiency is ensured, and meanwhile, when a shorter vehicle is disinfected, only the lower spray head 9 is opened for spraying disinfection, so that the disinfectant waste is avoided, and the effect of further saving the cost is achieved; because the metal signal that switch board 3 must detect earlier, and detect the metal signal and need last to detect that there is the vehicle signal to trigger main solenoid valve 12 and open by photoelectric switch 15, when the vehicle is gone out the gate from disinfection passageway 1, because switch board 3 detects photoelectric switch 15 earlier, consequently, spray mechanism 4 and shower do not start, play the effect of further saving cost.
