As shown in fig. 1, the digital display type liquid pressure exploring apparatus provided by this embodiment includes a pressure display apparatus 1, a pressure conducting apparatus 2, and a liquid storage tube 3, which are sequentially arranged from bottom to top.
The pressure display device 1 is a digital balance, the common digital balance can be accurate to 0.1g, the precision requirement of liquid pressure calculation can be met, and although the precision of a professional pressure sensor is better, the price is too high, so the digital balance is selected as the pressure display device 1 in the embodiment, and the pressure conduction device 2 is placed at the periphery of a scale pan of the digital balance.
The pressure conducting means 2 comprises a reservoir 21, a cylinder 22 and a piston rod 23. The liquid storage box 21 is a cuboid box body made of a transparent acrylic plate, a partition plate 24 is arranged in the cuboid box body, the partition plate 24 divides an inner cavity of the liquid storage box 21 into an upper cavity and a lower cavity, the cavity on the upper portion is a liquid storage cavity, and the cavity on the lower portion is a conduction cavity. The top surface center of stock solution box 21 sets up the screw hole as the connecting hole, and the middle part of baffle 24 sets up the mounting hole and is used for connecting cylinder body 22 to establish sealing washer 4 in the mounting hole and in order to improve the sealed effect of connecting the face. The piston end of the piston rod 23 is arranged in the cylinder body, and the other end is externally provided with a pressure transmission plate 25 which is designed into a single-volume square plate or a single-volume round plate so as to convert the pressure and the pressure intensity. When the liquid storage device is used, liquid is filled into the liquid storage cavity from the connecting hole, the piston rod moves downwards to be in contact with the pressure display device, and then the liquid storage tube 3 can be installed. The cylinder 22 and the piston rod 23 of the pressure conduction device 2 can be manufactured by using a syringe, and the needle of the syringe is removed to leave other parts.
The liquid storage pipe 3 selects a transparent acrylic pipe, the outer wall of the bottom end of the liquid storage pipe is provided with threads, scales are arranged on the outer wall of the liquid storage pipe along the length direction of the pipe, a water baffle 5 is arranged at the position of a zero scale line, and the water baffle 5 can move along the radial direction of the liquid storage pipe 3 to control the opening and closing of the liquid storage pipe 3. When the device is put into use, the water baffle 5 closes the liquid storage pipe 3, liquid with a certain depth is injected into the liquid storage pipe 3, the liquid storage pipe 3 is connected to the connecting hole at the top of the liquid storage box 21 in a threaded manner, the water baffle 5 is opened, the liquid enters the liquid storage box 21 from the liquid storage pipe 3 and then enters the cylinder body 22 to push the piston rod 23 to press the pressure display device 1 downwards, the pressure display device 1 displays pressure, and the pressure intensity of the liquid with the corresponding depth can be converted according to the volume of the pressing plate 25.
The liquid storage pipes 3 which are installed with different liquid in different depths can find that the pressure intensity of the same liquid is changed after the depth of the same liquid is changed, and the liquid storage pipes 3 which are installed with different diameters can find that the pressure intensities of the liquid storage pipes 3 with different diameters are the same under the same depth. Therefore, the pressure generated by the same liquid can be intuitively demonstrated to be only related to the depth and not related to other physical quantities.
When the liquid pressure display device is put into use, liquid with a certain depth is injected into the liquid storage pipe, the liquid storage pipe is communicated with the cylinder body, the piston rod has a movement trend relative to the pressure display device under the action of pressure, the pressure display device displays the pressure, then the liquid storage pipe is taken down, liquid with other depths is injected into the liquid storage pipe, the liquid storage pipe is communicated with the cylinder body, and the pressure display device displays another numerical value at the moment, so that the relation between the liquid depth and the liquid pressure can be demonstrated in a digital display mode, and meanwhile, the liquid pressure at different depths can be measured.
