[0020] The beneficial effects of the utility model are mainly:

[0021] 1. When the concrete maintenance device of the utility model is used, it is placed on the surface of the concrete component to be sprayed with water for maintenance. The pipeline on-off valve is controlled by the control mechanism to open so as to connect the connecting water pipe. The water in the water tank will enter the connecting water pipe. The water in the connecting water pipe will flow to the longitudinal water pipe and then flow downward through the spray head to wet the surface of the concrete component. The utility model can be moved to the left by the roller to sprinkle water on the surface of the concrete component. After the movement of the utility model is stopped, the pipeline on-off valve is controlled by the control mechanism to close so as to block the connecting water pipe. The water in the water tank will not flow to the longitudinal water pipe through the connecting water pipe, and the spray head will no longer flow water downward. Therefore, it has a clever design and a simple structure, can spray water on the surface of the concrete component to maintain the concrete component, and reduces the production cost and the use cost, which is suitable for large-scale promotion and application.

[0022] 2. In the case where the pipeline on-off valve of the utility model is a push-type valve, by pushing the push rod to the left, the push rod will slide to the left for a distance relative to the base, and the front limit rod and the rear limit rod will move to the left relative to the base through the front connecting rod and the rear connecting rod respectively, driving the sliding rod to move to the left relative to the base, thereby pressing the button of the push-type valve to the left, thereby opening the push-type valve, connecting the water pipe, and the water in the water tank will enter the connecting water pipe. The water in the connecting water pipe will flow to the longitudinal water pipe and then flow downward through the sprinkler head, soaking the surface of the concrete component and continuing to flow to the When the push rod is pushed to the left, the utility model will move to the left through the roller, thereby sprinkling water on the surface of the concrete component. If the push rod is no longer pushed to the left, the sliding rod will no longer press the button of the push-type valve to the left, and the button of the push-type valve will automatically reset to close the push-type valve, thereby blocking the connecting water pipe. The water in the water tank will not flow to the longitudinal water pipe through the connecting water pipe, and the sprinkler head will no longer flow water downward. Therefore, once it moves, it starts to spray water to maintain the concrete component, and once it stops moving, it stops spraying water. It is easy to use, saves water resources, and is suitable for large-scale promotion and application.
