Specific implementation manner

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0016] Referring to Figures 1-4 , a monitoring device for a hydraulic fracturing device includes: Fixing platform 1, a hydraulic pump 2 is fixedly installed at the top of the fixing platform 1, a fixing pipe 6 is fixedly connected to the hydraulic pump 2, the fixing pipe 6 penetrates through the fixing platform 1 and extends below the fixing platform 1, and the hydraulic pump 2 pumps water into the fixing end 6; Flow velocity detection structure, including a mounting plate 13 fixedly connected to the inner wall of the fixing pipe 6, an adjusting cavity 14 is opened inside the mounting plate 13, a moving block 15 is slidably connected to the inner wall of the adjusting cavity 14, a fixing rod 17 is fixedly connected to the top end of the moving block 15, and the fixing rod 17 penetrates through the upper inner wall of the adjusting cavity 14 and extends above the mounting plate 13, the top end of the fixing rod 17 is fixedly connected to an impact plate 25, a fixing spring 16 is fixedly connected to the bottom end of the moving block 15, one end of the fixing spring 16 away from the moving block 15 is fixedly connected to the lower inner wall of the adjusting cavity 14, a sliding groove 23 is opened on the inner wall of the adjusting cavity 14, a sliding block 24 corresponding to the sliding groove 23 is fixedly connected to the side wall of the moving block 15, one end of the sliding block 24 away from the moving block 15 is fixedly connected to an indicating plate 7, and a flow velocity meter corresponding to the indicating plate 7 is written on the side wall of the fixing pipe 6; When water flows through the fixed pipe 6, it will impact the impact plate 25, causing the impact plate 25 to move downward, driving the fixed rod 17 and the moving block 15 to move accordingly. The fixed spring 16 contracts. At the same time, as the water flow velocity changes, the impact force on the impact plate 25 also changes. Therefore, the deformation degree of the fixed spring 16 also changes accordingly. The moving block 15 moves. When the moving block 15 moves, the sliding block 24 fixedly connected to the moving block 15 moves together, driving the indicator plate 7 to move. The water flow velocity can be clearly seen through the flow meter, thus facilitating the adjustment of the hydraulic pump 2 to control the water pressure; A second detection structure is installed on the hydraulic pump 2. The second detection structure includes a resistance rod 10. A fixed frame 11 is fixedly installed on the resistance rod 10. The fixed frame 11 is fixedly connected to the bottom end of the fixed table 1. A conductive block 9 is slidably sleeved on the resistance rod 10. Wiring posts are fixedly installed on both the conductive block 9 and the resistance rod 10. A control device 3 is fixedly installed on the top end of the fixed table 1. The control device 3 can detect the current and simultaneously display the change curve of the current on the display screen. In cooperation with the flow meter, the water flow rate can be calculated. The wiring posts are connected to the control device 3 through wires. A regulating block 8 is fixedly connected to the side wall of the conductive block 9. The regulating block 8 is fixedly connected to the side wall of the indicator plate 7; When the indicator plate 7 moves, the regulating block 8 fixedly connected to the side wall of the indicator plate 7 moves accordingly, driving the conductive block 9 to move. When the conductive block 9 moves, the distance between the two wiring posts changes. Therefore, the current in the entire circuit also changes. The change curve graph can be seen from the display screen of the control device 3, thereby monitoring the flow rate; The control device 3 is equipped with an input keyboard, and a controller corresponding to the hydraulic pump 2 is installed on the control device 3. The control device 3, the controller, and the hydraulic pump 2 are existing matching devices, so their working principles will not be described in detail; A sealing gasket 18 is slidably sleeved on the outside of the fixed rod 17, and the sealing gasket 18 is closely attached to the top end of the mounting plate 13. The bottom end of the sealing gasket 18 is fixedly connected to a connecting rod 19. The connecting rod 19 penetrates the upper inner wall of the adjusting cavity 14 and extends to the inside of the adjusting cavity 14. A connecting cylinder 20 is sleeved on the part of the connecting rod 19 located inside the adjusting cavity 14. One end of the connecting rod 19 located inside the connecting cylinder 20 is fixedly connected to a connecting block 21, and the connecting block 21 is slidably connected to the inner wall of the connecting cylinder 20. The bottom end of the connecting block 21 is fixedly connected to a connecting spring 22. The end of the connecting spring 22 away from the connecting block 21 is fixedly connected to the lower inner wall of the connecting cylinder 20. In the initial state, that is, when the impact plate 25 is not impacted, the connecting spring 22 is in a normal state; When the moving block 15 moves downward, it will drive the connecting cylinder 20 to move accordingly, stretching the connecting spring 22, thereby exerting a force on the connecting block 21 and the connecting rod 19, and the direction of the force is downward. Therefore, the sealing gasket 18 is also subjected to a downward force, making the sealing effect of the sealing gasket 18 better, avoiding water leakage, and being beneficial to the use of the device; The bottom end of the fixed platform 1 is fixedly connected with a support rod 4. A buffer rod 5 is slidably sleeved on the outer side of the support rod 4. A buffer spring 12 is fixedly installed between the inner walls of the support rod 4 and the buffer rod 5. A damper is fixedly installed on the buffer spring 12. The buffer spring 12 is fixedly connected to the support rod 4 and the buffer rod 5 through the damper. The buffer spring 12 and the damper form a device to achieve the effect of shock absorption and buffering. During the operation of the hydraulic pump 2, the buffer spring 12 cooperates with the damper to weaken the vibration of the hydraulic pump 2 and prevent the hydraulic pump 2 from being affected by vibration; A protection plate is fixedly installed between the hydraulic pump 2 and the fixed platform 1. The hydraulic pump 2, the fixed platform 1 and the protection plate are all fixedly connected by fixing bolts. The protection plate further protects the hydraulic pump 2 to prevent it from being damaged; A wiring port is fixedly installed on the fixed platform 1.

The wiring port is connected to components such as an electric plug to facilitate the supply of electrical energy to the device.

[0017] In the present invention, when the device is in use, the hydraulic pump 2 is started. The hydraulic pump 2 pumps water flow from the fixed pipe 6. When the water flow passes through the fixed pipe 6, it will impact the impact plate 25, causing the impact plate 25 to move downward, driving the fixed rod 17 and the moving block 15 to move accordingly. The fixed spring 16 contracts. At the same time, as the water flow velocity changes, the impact force received by the impact plate 25 also changes. Therefore, the deformation degree of the fixed spring 16 also changes accordingly. The moving block 15 moves. When the moving block 15 moves, the sliding block 24 fixedly connected to the moving block 15 moves together, driving the indicator plate 7 to move. The flow velocity of the water flow can be clearly seen through the flow velocity meter, thus facilitating the adjustment of the hydraulic pump 2 to control the water pressure. At the same time, when the indicator plate 7 moves, the adjustment block 8 fixedly connected to the side wall of the indicator plate 7 moves accordingly, driving the conductive block 9 to move. When the conductive block 9 moves, the distance between the two wiring posts will change. Therefore, the current in the entire circuit will also change. The changing curve graph can be seen from the display screen of the control device 3, thereby monitoring the flow rate. Moreover, when the moving block 15 moves downward, it will drive the connecting cylinder 20 to move accordingly, stretching the connecting spring 22, thereby exerting a force on the connecting block 21 and the connecting rod 19, and the direction of the force is downward. Therefore, the sealing gasket 18 is also subjected to a downward force, making the sealing effect of the sealing gasket 18 better, avoiding water leakage, and being beneficial to the use of the device. In addition, during the operation of the hydraulic pump 2, the buffer spring 12 cooperates with the damper to weaken the vibration of the hydraulic pump 2 and prevent the hydraulic pump 2 from being affected by vibration.
