The invention discloses a drilling platform production liquid pipe high-precision flow device, which has the following working principle: the device is installed on the pipeline of the produced liquid in series through the detection pipeline 101, when fluid passes through the detection pipeline 101, the central detection resistance disc 201 and the edge detection resistance plate 106 can be impacted, because friction exists between the produced liquid and the inner wall of the detection pipeline 101, the fluid flow rate close to the inner wall of the detection pipeline 101 is lower than the middle flow rate, the traditional flow sensor can not detect the fluid, the movable edge detection resistance plate 106 is required to be arranged, and the flow plates 102 arranged on the two sides of the edge detection resistance plate 106 can prevent the fluid flowing on the surface of the edge detection resistance plate 106 from flowing to the other side, so that the flow rate of the fluid is influenced. Since the viscosity of different densities is different at the flow speed of the inner wall surface of the detection pipe 101, the edge detection resistance plate 106 needs to be moved, specifically, by controlling the movement of the telescopic rod of the adjusting cylinder 110, the telescopic rod of the adjusting cylinder 110 moves to drive the edge detection resistance plate 106 to swing on the resistance plate bracket 108, so that the swing angle of the edge detection resistance plate 106 is changed, and the swing angle of the edge detection resistance plate 106 is known, so that when fluid impacts the edge detection resistance plate 106, the resistance of the edge detection resistance plate 106 by the fluid is known, the impact force of the fluid received by the edge detection resistance plate 106 is transmitted to the resistance plate bracket 108, then the resistance plate bracket 108 transmits the force to the pressure plate 105, the bottom pressure sensor 104 can measure the pressure, the fluid flow velocity of the inner wall edge of the detection pipe 101 can be calculated through the pressure value, and the thickness of the edge is the drop height of the swing angle of the edge detection resistance plate 106.
The flow rate of the fluid in the middle of the detection pipeline 101 is calculated through the resistance received by the central detection resistance disc 201, in order to improve the detection precision, a bottom pressure sensor 104 (the action is the same as that of the bottom pressure sensor 104, but the fluid can only be used when the temperature of the fluid is relatively constant, and the too high or too low temperature can not be used), while the force received by the central detection resistance disc 201 is transmitted to a rotating cylinder shaft 206 through a resistance disc supporting rod 202, and then the rotating cylinder shaft 206 transmits the force to a top supporting pressing block 205, and the pressure is obtained by pressing a top pressure sensor 203. In order to reduce the obstruction of the central detection resistance disc 201 to the fluid, the swing angle of the central detection resistance disc 201 is adjusted according to the fluids with different densities, specifically, by controlling the rotation of the output shaft of the adjustment power motor 214, the output shaft of the adjustment power motor 214 drives the adjustment input disc 213 to rotate, the adjustment input disc 213 drives the toggle rod 218 to rotate, the toggle rod 218 drives one of the two friction pins 216 to rotate (see the rotation direction), then the friction pin 216 compresses the elastic part 217 and then drives the unidirectional rotation block 212 to rotate, the unidirectional rotation block 212 rotates and drives the input compensation sliding frame 209 to rotate, the input compensation sliding frame 209 rotates and drives the intermediate compensation sliding block 208 to rotate through the intermediate compensation sliding block 208, the output compensation sliding frame 207 rotates and drives the rotation cylinder shaft 206 to rotate, and the rotation cylinder shaft 206 rotates through the resistance disc support rod 202 to drive the central detection resistance disc 201 to swing, so that the included angle between the central detection resistance disc 201 and the fluid flow direction is changed, and the resistance of the central detection resistance disc 201 to the fluid is changed, and the pressure drop of the north fluid is reduced. Therefore, the flow of fluid will also apply a force to the center detecting resistance disc 201, so that the center detecting resistance disc 201 rotates (the center detecting resistance disc 201 needs not to rotate), the center detecting resistance disc 201 will receive the torque, the center detecting resistance disc 201 transmits the torque to the resistance disc support rod 202, then transmits the torque to the rotating cylinder shaft 206, then transmits the torque to the output compensating sliding frame 207, and transmits the torque to the input compensating sliding frame 209 through the middle compensating sliding block 208, then transmits the torque to the unidirectional rotating block 212, the unidirectional rotating block 212 rotates to drive the friction pin 216 in the slope sliding groove to rotate, as shown in fig. 11, when the unidirectional rotating block 212 rotates clockwise, the friction pin 216 will also rotate clockwise, at this time, the right friction pin 216 will receive the friction force from the unidirectional rotating groove 211 along the anticlockwise direction, so that the right friction pin 216 moves upwards along the slope groove, so that the space gradually decreases, and further increases the friction force between the unidirectional rotating groove 211 and the slope surfaces of the slope sliding groove will squeeze the friction pin 216, so that the unidirectional rotating block 211 and the unidirectional rotating block 212 will not die, and the unidirectional rotating block 212 cannot rotate due to the unidirectional rotating block 212, and the unidirectional rotating shaft 216 cannot be rotated due to the fact that the unidirectional rotating is not able to be adjusted when the unidirectional rotating block 212 is rotated (218). The torque applied to the center sensing resistive disc 201 by the fluid cannot be transferred to the adjustment input disc 213 and thus cannot rotate the center sensing resistive disc 201. The length of the resistance disc support rod 202 can be prolonged, so that the other end of the resistance disc support rod 202 and the inner wall of the detection pipeline 101 rotate, and the support strength of the resistance disc support rod 202 to the center detection resistance disc 201 (the position where the edge detection sliding groove 1011 needs to be avoided) is increased.
Since the thickness of the fluid to be detected at the edge of the detection pipe 101 is known, the cross-sectional area of the fluid near the edge of the detection pipe 101 is also known, and therefore the cross-sectional area of the intermediate fluid is also known, so that the flow rates of the two fluids are calculated and overlapped (vector overlapped) respectively, and the fluid velocity and the flow rate in the detection pipe 101 can be calculated.
