Technical Field

[0001] The utility model relates to the technical field of railway transportation dust suppression, in particular to an intelligent dust suppression spraying device for railway transportation. Background Technique

[0002] The railway transportation dust suppression device is mainly aimed at the coal dust scattering caused by factors such as running wind during the process of loading coal by railway freight cars. The common dust suppression means is to spray dust suppression liquid after loading for treatment.

[0003] However, the common automatic control of spraying dust suppression liquid only senses and detects whether there is a vehicle, and then emits a radio frequency signal to control the realization of spraying. It cannot distinguish between the locomotive and the freight car carriage, which will lead to a series of problems. For example, the dust suppression liquid is sprayed on the top of the locomotive, corroding components such as the pantograph of the locomotive; the dust suppression liquid is sprayed on the driver's cab observation window, directly affecting the driver's observation vision and signal confirmation, and there is a risk of train operation safety; the dust suppression liquid flows to parts such as the boarding and alighting ladder and handrail, posing a personal safety risk to the crew during boarding and alighting, etc. And spraying dust suppression liquid on the locomotive is an ineffective raw material consumption, increasing the dust suppression cost and being unfavorable for cost reduction, energy conservation and green ecology.

[0018] Please refer to Figure 1 , the present utility model provides a technical solution: including a liquid storage tower 1 and a spray tower 2, a connecting pipe 3 is installed and connected between the spray tower 2 and the liquid storage tower 1, a first electric ball valve 31 and a power pump 32 are installed on the connecting pipe 3, a reflux pipe 4 is fixed between the connecting pipe 3 and the liquid storage tower 1, a second electric ball valve 41 is installed on the reflux pipe 4, a spray head 5 is fixed at the upper end of the spray tower 2, the end of the connecting pipe 3 is fixed on the spray head 5, a camera 7 and a sensor 6 are fixed on the spray tower 2, the camera 7 and the sensor 6 are electrically connected to the first electric ball valve 31 and the second electric ball valve 41 through an industrial control host, a protective frame 8 is fixed on the spray tower 2 and around the camera 7 and the sensor 6, a glass plate 81 is fixed on the front side of the protective frame 8, an automatic cleaning assembly for cleaning the glass plate 81 is arranged on the spray tower 2, the first electric ball valve 31 is installed on the connecting pipe 3 and is located between the end of the reflux pipe 4 and the spray head 5, control current switches are installed on both the first electric ball valve 31 and the second electric ball valve 41, and a controllable relay electrically connected to the control current switch is installed on the industrial control host.

[0019] The automatic cleaning assembly includes a carrier plate 9 and a brush 92. The carrier plate 9 is fixed on the spray tower 2 and outside the protective frame 8. A sliding block 91 is slidably connected to the inner side of the carrier plate 9. The brush 92 is fixed on the sliding block 91, and the brush head of the brush 92 corresponds to the glass plate 81. A limiting groove 93 is opened at a position corresponding to the sliding block 91 on the carrier plate 9. A driving structure is arranged outside the carrier plate 9. The driving structure includes a mounting plate 94 and a servo motor 97. The mounting plate 94 is fixed outside the carrier plate 9 and at both ends of the limiting groove 93. A threaded rod 95 is rotatably connected between the two mounting plates 94. A driving plate 96 is threadedly connected to the threaded rod 95. The end of the driving plate 96 passes through the limiting groove 93 and is fixed on the sliding block 91. The servo motor 97 is fixed on the upper end of the upper mounting plate 94, and the output end of the servo motor 97 is fixed to the upper end of the threaded rod 95.

[0020] Working principle: First, connect the entire device to an external power supply. Then, use the sensor 6 for monitoring. If there is a locomotive, it will emit a radio frequency signal to the industrial control host, and the camera 7 will capture real-time images to distinguish the color of the locomotive. The carriage part is dark gray, and there is a large color difference on the locomotive body, so as to distinguish the locomotive from the carriage. When the carriage passes under the sprinkler head 5, the first electric ball valve 31 can be opened, and the power pump 32 is used to transport the liquid in the liquid storage tower 1 to the sprinkler head 5 through the connecting pipe 3 and finally spray it out. At this time, the second electric ball valve 41 is in the closed state. On the contrary, when there is no locomotive or when it is not the carriage passing by, the first electric ball valve 31 can be closed, and at the same time, the second electric ball valve 41 can be opened to make the liquid flow back, turn off the spray, and at the same time avoid damage to the valve body caused by water pressure impact. During daily maintenance, the servo motor 97 can be used to drive the rotation of the threaded rod 95, so that the driving plate 96 slides reciprocally between the mounting plates 94, and then drives the sliding block 91 and the brush 92 to slide. Finally, the brush 92 is used to clean the dust on the surface of the glass plate 81 to avoid the influence of dust on the monitoring and recognition of the camera 7 or the sensor 6, without manual maintenance, reducing the labor cost.
