[0026] See also Figure 1 and Figure 2 A LED tunnel light spray test device includes: a main body 100, a spray assembly and a blow pipe 300, the main body 100 is provided with a rectangular conveying chamber 110, the lower part of the conveying chamber 110 is connected with a recovery chamber, and the conveying chamber 110 is equipped with a conveying assembly for transporting the LED tunnel light; the spray assembly includes a water outlet pipe 200 and a return pipe 210, part of the water outlet pipe 200 is built in the conveying chamber 110, the water outlet pipe 200 is provided with a plurality of nozzles 201 for discharging water downward, the return pipe 210 is connected with the recovery chamber, and a water pump 220 is connected between the water outlet pipe 200 and the return pipe 210; part of the blow pipe 300 is built in the conveying chamber 110, the conveying chamber 110 is equipped with a swing rod 310, the output end of the blow pipe 300 is relatively fixedly arranged at one end of the swing rod 310, and the other end of the swing rod 310 is connected with a driving assembly for driving it to rotate, so that the swing rod 310 can change the blowing direction of the output end of the blow pipe 300.

[0027] When the LED tunnel lamp spray test device of the above structure is used, the LED tunnel lamp to be tested is placed on the conveying assembly, so that the LED tunnel lamp can move along the length direction of the conveying cavity 110, and then the water outlet pipe 200 and the air blowing pipe 300 are turned on, so that water passes through the nozzle 201 on the water outlet pipe 200 to form a downward spraying effect, thereby simulating a dripping and humid environment in the tunnel, and the airflow generated by the air blowing pipe 300 can disturb the direction of water falling. Finally, the driving assembly drives one end of the swing rod 310 to deflect, thereby changing the blowing direction of the output end of the air blowing pipe 300, which is conducive to simulating the environment in the tunnel where there is wind and causes dripping or disordered distribution of humid water vapor, and finally the LED tunnel lamp is in a more realistic simulation environment, which is conducive to improving the reliability of the waterproof test of the LED tunnel lamp.

[0028] Furthermore, the drive assembly includes a motor, the output end of the motor is connected to a driving gear, the driving gear is transmission-connected to a driven gear, and the driven gear is coaxially connected to the other end of the swing rod 310. Specifically, the motor drives the driving gear to rotate, so that the driven gear drives one end of the swing rod 310 to deflect, thereby changing the blowing direction of the output end of the blowing pipe 300, which is conducive to simulating the airflow environment in different directions inside the tunnel in different time periods. It can be understood that the cooperation of the driving gear and the driven gear, on the one hand, improves the reliability of the torque transmission of the motor, and on the other hand, the rotation speed of the output end can be adjusted by different numbers of gear teeth, which is conducive to reducing the rotation speed of the swing rod 310. In some embodiments, the drive assembly can also be replaced by a motor-driven pulley, which is not described in detail here.

[0029] See also Figure 1 and Figure 2 Furthermore, a rotating shaft is connected between the driven gear and the swing rod 310, a mounting plate 120 is built into the delivery chamber 110, the rotating shaft is arranged on the mounting plate 120, two elastic sheets 311 are arranged oppositely at one end of the swing rod 310 away from the rotating shaft, and the blowing pipe 300 is sandwiched between the two elastic sheets 311. Specifically, the mounting plate 120 is fixed to the side wall of the delivery chamber 110, the mounting plate 120 is provided with a through hole for the rotating shaft to pass through, one end of the swing rod 310 is threadedly matched with the rotating shaft, and the elastic sheet 311 is fixed to the other end of the swing rod 310 in an integrated manner, so that it is convenient for people to fix the position of the blowing pipe 300. Among them, the two elastic sheets 311 are arranged obliquely relative to the swing rod 310, so as to form a mounting channel with a variable spacing, which is conducive to the elastic sheet 311 to better clamp the blowing pipe 300.

[0030] See also Figure 1 and Figure 2 Further, the mounting plate 120 is provided with an arc hole 121, and the arc hole 121 is located below the rotating shaft, and the swing rod 310 is provided with a guide shaft 312 adapted to the arc hole 121. Specifically, the cooperation between the guide shaft 312 and the arc hole 121 is conducive to forming a guiding and limiting effect of the deflection of the swing rod 310, and is also conducive to forming the effect of supporting the blowing pipe 300. It can be understood that the arc hole 121 is a semicircular arc hole, and the swing rod 310 swings back and forth through the forward and reverse rotation of the motor.

[0031] See also Figure 1 and Figure 2Furthermore, two opposite side walls of the conveying chamber 110 are provided with mounting plates 120, and each mounting plate 120 is correspondingly provided with a swing rod 310. The blowing pipe 300 includes a blowing section, and the blowing section has a plurality of output ports for blowing air downward. The blowing section is installed between the two swing rods 310, so that the blowing section can form an effect of being placed horizontally in the conveying chamber 110, which is beneficial for the blowing section to blow air from different positions through different output ports, thereby facilitating the water output from the water outlet pipe 200 to change the falling direction due to the wind force at different positions.

[0032] Furthermore, the delivery chamber 110 is provided with two blowing pipes 300 along its length direction, and the two blowing pipes 300 are located on both sides of the nozzle 201, and each blowing pipe 300 is correspondingly connected to a swing rod 310, and each swing rod 310 is correspondingly connected to a driving assembly, and the motors in the two driving assemblies are electrically connected to a control module. Specifically, the two blowing pipes 300 are distributed on both sides of the water outlet pipe 200, and the blowing pipe 300 close to the entrance of the delivery chamber 110 forms the first blowing, and the blowing pipe 300 close to the exit of the delivery chamber 110 forms the second blowing, and the control module can control the independent operation of the two motors in sections through program input. Among them, the LED tunnel lights can be transported in batches. Before the LED tunnel lights pass through the first blowing pipe 300, the first blowing can be used to blow off dust and other debris on the LED tunnel lights. Then, when the LED tunnel lights are transported between the two blowing pipes 300 for spraying, the output ends of the two blowing pipes 300 are tilted toward one side of the water outlet pipe 200, so that the blowing pipes 300 are used to change the falling direction of the water sprayed from the nozzle 201, thereby simulating the environment in the tunnel where there is wind disturbing dripping water or water vapor. Finally, after the LED tunnel lights are transported to the second blowing pipe 300, the second blowing can be used to blow off water droplets on the LED tunnel lights, thereby accelerating the drying of the LED tunnel lights.

[0033] Furthermore, the blowing pipe 300 is a flexible pipe, one end of which passes through the outside of the main body 100, and one end of which is connected to an air compressor, so that the airflow generated by the air compressor is output through the blowing pipe 300. The blowing pipe 300 can be a flexible pipe made of rubber material, so that the blowing pipe 300 can be adaptively bent to be fixed on the swing rod 310.

[0034] See also Figure 1 Furthermore, the conveying component is a chain plate conveyor belt, which includes a plurality of conveying plates 130, and the plurality of conveying plates 130 are spaced apart along the length direction of the conveying chamber 110, so that the sprayed water can fall into the recovery chamber through the gap between the two conveying plates 130, thereby facilitating the subsequent water pump 220 to continue to extract the water from the recovery chamber, so that the water can be re-sprayed through the water outlet pipe 200, saving water resources.

[0035] Furthermore, a plurality of water outlet pipes 200 are provided, and the plurality of water outlet pipes 200 are spaced apart along the length direction of the delivery cavity 110, and the plurality of water outlet pipes 200 are commonly connected to a manifold 230, and the manifold 230 is connected to a water pump 220, so that water is diverted to the plurality of water outlet pipes 200 through the manifold 230 for output. Specifically, the provision of the plurality of water outlet pipes 200 is conducive to extending the spraying time of the LED tunnel light, thereby improving the waterproof test effect of the LED tunnel light.

[0036] Furthermore, the side wall of the conveying chamber 110 is a transparent member, so that people can observe the internal conveying or spraying conditions of the conveying chamber 110 easily.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
