Washing and sweeping vehicle and water drainage and pipe cleaning method thereof
The invention belongs to the technical field of washing and sweeping vehicles, and particularly relates to a washing and sweeping vehicle and a water drainage and pipe cleaning method thereof. In the washing and sweeping vehicle, a gas source supplies air to a water outlet main pipe through pipe cleaning electromagnetic valves so as to clean pipes; the gas source also provides driving force for pneumatic control valves on water outlet branch pipes; and the pneumatic control valve is controlled by water outlet electromagnetic valves. When the water drainage and pipe cleaning are operated, the pipe cleaning electromagnetic valves are controlled to be opened, all the water outlet electromagnetic valves are controlled to be opened gradually, and only one water outlet electromagnetic valve is in an opened state each time: gas in the gas source enters the corresponding gas control valve to enable the gas control valve to act, the corresponding water outlet branch pipe is conducted, the gas in the gas source passes through the pipe cleaning electromagnetic valves, and the water sequentially enters the water outlet branch pipes to realize water drainage and pipe cleaning. According to the invention, only one water outlet branch pipe is subjected to water drainage and pipe cleaning every time, and after residual water of one water distribution branch pipe is completely drained, the next water distribution branch pipe is subjected to water drainage and pipe cleaning operation, so that the optimal pipe cleaning effect is ensured, the washing and sweeping vehicle can be normally used under the condition of lower air temperature, and the operation efficiency of the washing and sweeping vehicle is ensured.
本发明属于洗扫车技术领域，具体涉及一种洗扫车及其排水净管方法。该洗扫车中气源通过净管电磁阀为出水总管供气，以进行净管；气源还为出水支管上的气控阀提供驱动力；气控阀由出水电磁阀进行控制。排水净管操作时，控制净管电磁阀打开，控制各出水电磁阀逐次打开，且每次只有一个出水电磁阀处于打开状态：气源中气体进入相应的气控阀使气控阀动作，相应出水支管导通，气源中的气体经过净管电磁阀后，依次进入各出水支管实现排水净管。本发明每次只对一条出水支管进行排水净管，在其中一条分水支管的余水排净后再对下一条分水支管进行排水净管作业，保证最佳净管效果，使得洗扫车在气温较低的情况也能够正常使用，保证了洗扫车的作业效率。
