The invention discloses an automatic sand preparation system for a water tank test, which comprises a sand adding device, a water inlet system, a water outlet system and an automatic control system, a water outlet level and a target water inlet flow rate are set on a computer, the flow rate of a water inlet pipe is adjusted to make the value of a first flowmeter equal to the target water inlet flow rate, and the flow rate of a water outlet is adjusted to make the value of a second flowmeter equal to the target water inlet flow rate. The numerical value of the second flow meter is equal to that of the first flow meter; the computer calculates the sand content in the mixing bin according to the turbidity value, if the sand content is inconsistent with the target sand content, the water inflow is kept unchanged, the rotating speed of the motor is integrally adjusted, and a water outlet system is started when the water level reaches the set water level. Sand adding, water feeding, stirring and water discharging are integrated into a whole, the water feeding system, the water discharging system and the sand feeding amount are controlled in real time on the basis of feedback of a sensor, in the process that sand adding, water feeding and stirring are conducted at the same time, accurate measurement and control over water and sand are achieved, stirring is achieved through inflow water flow, and an additional stirring device does not need to be arranged.
本发明公开了一种水槽试验用自动配沙系统，包括加沙装置、进水系统、出水系统和自动控制系统，在电脑上设定好出水水位和目标进水流量，通过调节进水管的流量，使第一流量计的数值与目标进水流量相等，通过调节出水口处的流量，使第二流量计的数值与第一流量计的数值相等；电脑根据浊度值计算混合仓内的含沙量，若与目标含沙量不一致，保持进水量不变，整体调整电机的转速，待水位达到设定水位即开启出水系统。本发明将加沙、进水、搅拌、出水集成为一个整体，基于传感器的反馈，实时控制进、出水系统和进沙量，在加沙、进水和搅拌同时进行的过程中，实现了对水沙的精确测量与控制，且利用进水水流实现搅拌，无需设置额外的搅拌装置。
