Abstract

The invention discloses an improved hydrostatic pressure testing device and a testing method, and the device comprises a water storage device, a control mechanism, a leveling device, a pressure bearing device, and a measuring transmission device. The water storage device is used for supporting the whole device and temporarily storing the water for experiment. The control mechanism is used for controlling the water stored in the support to flow between the tank and the support. The leveling device is used for setting the tank to be in a horizontal state. The pressure bearing device is used forconverting the hydrostatic pressure into the rotational torque of the bearing body. The measuring transmission device is used for converting the rotational torque of the pressure bearing device into adeformation of the torsion spring, by which the torque of the torsion spring is obtained, thereby obtaining the value of the hydrostatic pressure, and further obtaining a quantitative relationship between the hydrostatic pressure and the water depth. The improved hydrostatic pressure testing device and the testing method are simple in structure and clear in principle, therefore, the accurate measurement of hydrostatic pressure, the law of hydrostatic pressure in different water depths, and the hydrostatic pressure action point can be obtained through the technical design of the invention.

Description

technical field [0001] The invention relates to a hydraulic experiment teaching instrument and a testing method thereof, in particular to an improved hydrostatic pressure testing experimental device and a testing method. Background technique [0002] The existing hydrostatic pressure demonstration experimental device is rough in measurement and has a single function. It is mainly composed of a water tank and a lever force-measuring mechanism. After stabilization, a weight of a certain mass is applied to one end of the lever, and the static water surface pressure is measured according to the principle of lever balance. [0003] However, due to systematic or random factors such as the difficulty in controlling the self-weight of the lever and the accuracy of the weight, and the large error in the judgment of the system balance by the human eye, the static water surface pressure measured by the existing device has a large error from the theoretical value. Examining the existin...
