Device for improving positioning precision of linear accelerator water tank

The utility model provides a device for improving the positioning accuracy of a linear accelerator water tank, which comprises a distilled water barrel, a water supply mechanism mounted on one side of the distilled water barrel, a water tank fixedly connected to one end of the water supply mechanism, a fixing piece mounted on the back of the water tank, water level scales fixedly arranged on one side of the water tank, and a mounting mechanism arranged at the top end of the water tank. According to the device for improving the positioning accuracy of the water tank of the linear accelerator, the water level in the water tank can be accurately positioned and fed back through the two water level detectors, when the water level in the water tank is lower than the minimum warning value, the water pump works, and the water tank is cleaned. When the water level reaches the highest warning, the electromagnetic valve installed on the surface of the water pipe controls water supplementation to prevent the water level
