[0014] Monitoring methods based on monitoring devices at the interfaces of oil extraction manifold components. S1: To detect leaks in the manifold assembly without using electrical equipment, hydraulic oil is filled into the monitoring housing through the filling port at the front end. The solenoid valve opens, and when the monitoring housing is full of hydraulic oil, the hydraulic oil compresses the silicone seal. Under pressure, the silicone seal moves, causing the first spring telescopic rod to extend. Under the tension of the first spring telescopic rod, the silicone seal remains in contact with the filling port. The diameter of the silicone seal is smaller than the diameter of the filling port. When the silicone seal moves away from the filling port, hydraulic oil enters the hydraulic groove from the filling port. When the hydraulic oil fills the glass column... After reaching the lowest point of the scale, the hydraulic oil comes into contact with the buoy ball, completing the filling process. When oil leaks from inside the manifold assembly, the hydraulic oil gradually enters the hydraulic groove. After the buoy ball comes into contact with the hydraulic oil, it moves. This movement of the buoy ball can drive the rubber column to move via the sliding roller. When hydraulic oil enters the hydraulic groove, the sliding roller drives the disc to move upward. The disc drives the second spring telescopic rod to extend. Under the elastic force of the second spring telescopic rod, when the rubber column moves away from the connecting through hole, the hydraulic oil enters the airbag through the connecting through hole and the guide pipe. At this point, the oil leakage situation of the manifold assembly can be monitored through the scale on the glass column.

[0015] S2: When quickly installing the monitoring component, the two monitoring housings are fitted together. The right-angle pressure plate fixed on one side of the monitoring housing is aligned with the ladder groove. The servo motor drives the double threaded rod to rotate. The double threaded rod drives the inner threaded plate connected by the outer spiral to move. According to the shape of the double threaded rod, the two inner threaded plates simultaneously drive the moving folding plate to move closer to the right-angle pressure plate. When the right-angle pressure plate enters the ladder groove, under the pressure of the moving folding plate, the rubber sheet in the middle of the moving folding plate, the left end and the right-angle pressure plate at the right end are pressed together. The right-angle pressure plate drives the monitoring housing to move closer at the same time. The two monitoring housings simultaneously press the hollow rubber ring. The hollow rubber ring drives the monitoring housing to be fixed at the same time. At this time, the quick installation of the monitoring component can be completed. S3: When protecting the monitoring components, after the hollow rubber ring is squeezed, the gas inside the hollow rubber ring enters the gas storage tank through the inner channel opened on the inner side of the cylinder. At this time, the gas inside the gas storage tank expands, the cylinder moves, and the gas storage shell drives the protective plate to move.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the scale lines are displayed intuitively, avoiding the inability to detect pipeline leaks due to power failure of electrical equipment, thus ensuring the normal use of the manifold assembly; 2. In this invention, by using the limiting slide groove, servo motor, double threaded rod, moving folding plate and monitoring housing, the device can quickly and stably fix the two monitoring housings, improving the installation and disassembly efficiency of the monitoring housings. At the same time, when fixing the two monitoring housings, the device can seal the monitoring housings and the manifold assembly. 3. In this invention, by using a protective plate, a buffer telescopic component, a hollow rubber ring, and a monitoring housing, the device allows the gas inside the hollow rubber ring to enter the buffer telescopic component during installation, keeping the protective plate away from the monitoring housing. This prevents external objects from damaging the monitoring component and reduces the impact force of external objects on the monitoring component. Attached Figure Description

[0021] Please see Figure 1-8 The present invention provides a technical solution: The monitoring device at the interface of the oil extraction manifold assembly of the present invention includes a manifold assembly 1 and a limiting groove 2.

The monitoring assembly 4 includes a monitoring housing 41. Right-angle pressure plates 42 are fixedly connected to the front and rear sides of the monitoring housing 41. A right-angle pressure plate 42 is fixedly connected to the right side of the monitoring housing 41. A hollow rubber ring 43 is attached. A buffer telescopic assembly 44 is fixedly connected to the outside of the monitoring housing 41. A protective plate 46 is fixedly connected to one side of the buffer telescopic assembly 44.

The display assembly 5 includes a glass column 51. A hydraulic groove 52 is opened on the inside of the glass column 51. A connecting through hole 53 is opened at the right end of the glass column 51. The inside of the glass column 51 is in contact with the outside of the buoyancy ball 54. A second spring telescopic rod 55 is fixedly connected to the top of the glass column 51. A disc 56 is fixedly connected to the top of the second spring telescopic rod 55. A sliding roller 58 is fixedly connected to the bottom of the disc 56. A rubber column 59 is fixedly connected to the outside of the sliding roller 58. A baffle 57 is fixedly connected to the top of the rubber column 59.

[0022] As a further implementation of this solution, the servo motor 31 is fixedly connected to the front of the manifold assembly 1 at the rear. The double threaded rod 32 is rotatably connected to the inner side of the manifold assembly 1. The double threaded rod 32 has two opposite threads on its outer side. The inner threaded plate 33 has a threaded hole on its inner side. The lower end of the inner threaded plate 33 is equipped with a limit slide. The inner threaded plate 33 is slidably connected to the inner side of the limit slide groove 2. There are two inner threaded plates 33. The front and rear shapes of the movable folding plate 34 are "U" shaped. The middle of the movable folding plate 34 is connected by a rubber sheet. The top view of the trapezoidal groove 35 is trapezoidal. The inner side of the trapezoidal groove 35 fits against the outer side of the right angle pressure plate 42, which helps to keep the U-shaped frame of the front and rear movable folding plate 34 close to each other, improves the stability of the movable folding plate 34 clamping the right angle pressure plate 42, and achieves the effect of rapid installation. As a further implementation of this solution, the monitoring housing 41 is hollow inside, and the right-angle pressure plate 42 is in the shape of a right-angled triangle. There are four right-angle pressure plates 42, which are fixed on the front and rear sides of the monitoring housing 41. One end of the monitoring housing 41 has a groove, and the hollow rubber ring 43 is embedded in the groove of the monitoring housing 41. According to the shape of the right-angle pressure plate 42, when the right-angle pressure plate 42 contacts the stepped groove 35, the monitoring housing 41 can be moved, so that the hollow rubber ring 43 seals the two monitoring housings 41, realizing the sealing function between the monitoring component 4 and the manifold component 1, and at the same time completing the installation of the monitoring housing 41. As a further implementation of this solution, the buffer telescopic assembly 44 includes an air storage shell 441, an air storage groove 442 is formed on the inner side of the air storage shell 441, a cylindrical column 443 is slidably connected to the air storage groove 442 formed on the inner side of the air storage shell 441, a silicone ring 444 is fixedly connected to the outer side of the cylindrical column 443, an inner channel 445 is formed on the inner side of the cylindrical column 443, a through hole is formed on the inner side of the monitoring shell 41, the outer side of the cylindrical column 443 is fixed inside the through hole of the monitoring shell 41, and a hollow rubber ring 43 is close to the cylindrical column. One end of 443 has an opening, and the cylindrical column 443 is connected to the through hole of the hollow rubber ring 43 through the inner channel 445. The outer side of the silicone ring 444 is fitted to the inside of the gas storage shell 441. The gas storage shell 441 is a hollow cylinder, and the inner channel 445 is connected to the inside of the gas storage groove 442. When the hollow rubber ring 43 is squeezed and deformed, the cylindrical column 443 and the gas storage shell 441 extend, thereby moving the protective plate 46 away from the monitoring shell 41 and achieving the effect of protecting the monitoring shell 41. As a further implementation of this solution, there are two filling holes 47. The filling holes 47 are opened at the front end and the rear end of the monitoring housing 41. The front side of the rear silicone seal 45 is attached to one side of the filling hole 47. The rear filling hole 47 is connected to the inside of the hydraulic groove 52, which facilitates the filling of hydraulic oil into the monitoring housing 41. This allows part of the hydraulic oil inside the monitoring housing 41 to flow into the hydraulic groove 52, thereby achieving the effect of real-time monitoring of the capacity inside the monitoring housing 41. As a further implementation of this scheme, one end of the glass column 51 is provided with a scale, the hydraulic groove 52 is connected to the inside of the connecting through hole 53, one side of the glass column 51 is fixedly connected to one side of the liquid guide tube 8, and the connecting through hole 53 is connected to the inside of the air bag 7 through the liquid guide tube 8 to prevent the mixture inside the monitoring housing 41 from overflowing. At this time, the oil leakage of the manifold assembly 1 can be monitored through the scale on the glass column 51. As a further implementation of this solution, the hydraulic groove 52 is cylindrical in shape. The outer side of the rubber column 59 fits against the inner side of the hydraulic groove 52 opened in the glass column 51. A baffle 57 is fixedly connected inside the hydraulic groove 52 opened in the glass column 51, which serves to reset the rubber column 59. The baffle 57 serves to limit the movement of the rubber column 59.

[0023] Workflow: To detect leaks in manifold 1 without using electrical equipment, the device is powered by an external power source during operation. Hydraulic oil is filled into the monitoring housing 41 through the filling port 47 at the front end. At this time, the solenoid valve 48 opens. When the monitoring housing 41 is full of hydraulic oil, the hydraulic oil compresses the silicone seal 45. Under the pressure, the silicone seal 45 moves, causing the first spring telescopic rod 49 to extend. Under the tension of the first spring telescopic rod 49, the silicone seal 45 is kept in contact with the filling port 47, thus sealing the filling port 47. The diameter of the silicone seal 45 is smaller than the diameter of the filling port 47. When the silicone seal 45 moves away from the filling port 47, hydraulic oil enters the hydraulic groove 52 from the filling port 47. When the hydraulic oil reaches the lowest point of the scale line on the glass column 51, the hydraulic oil comes into contact with the buoyancy ball 54, completing the filling process. When oil leaks from inside manifold 1... After leakage, hydraulic oil gradually enters the hydraulic groove 52. When the buoyant ball 54 comes into contact with the hydraulic oil, it moves. The movement of the buoyant ball 54 can drive the rubber column 59 to move via the sliding roller 58. The rubber column 59 seals the inside of the hydraulic groove 52 and also blocks the connecting through hole 53. When hydraulic oil enters the hydraulic groove 52, the sliding roller 58 drives the disc 56 to move upward. The disc 56 drives the second spring telescopic rod 55 to extend. Under the elastic force of the second spring telescopic rod 55, it resets the rubber column 59. The baffle 57 limits the movement of the rubber column 59. When the rubber column 59 moves away from the connecting through hole 53, the hydraulic oil enters the air bladder 7 through the connecting through hole 53 and the liquid guide pipe 8. The air bladder 7 stores the hydraulic oil and prevents the mixture inside the monitoring housing 41 from overflowing. At this time, the oil leakage of the manifold assembly 1 can be monitored by the scale on the glass column 51.

[0024] To quickly install the monitoring component 4, the two monitoring housings 41 are attached together. The right-angle pressure plate 42 fixed on one side of the monitoring housing 41 is aligned with the ladder groove 35. The servo motor 31 is started, which drives the double-threaded rod 32 to rotate. The double-threaded rod 32 drives the inner threaded plate 33 with its outer spiral connection to move. According to the shape of the double-threaded rod 32, the two inner threaded plates 33 simultaneously drive the moving folding plate 34 to move closer to the right-angle pressure plate 42. When the right-angle pressure plate 42 enters the ladder groove 35, the moving folding plate 34 moves closer to the right-angle pressure plate 42. Under the pressure of plate 34, the rubber sheet in the middle of the movable folding plate 34 plays a role in keeping the U-shaped frame of the front and rear movable folding plates 34 close together, improving the stability of the movable folding plate 34 clamping the right angle pressure plate 42. The right angle pressure plates 42 at the left and right ends come into close contact, and the right angle pressure plates 42 drive the monitoring housing 41 to move closer at the same time. The two monitoring housings 41 simultaneously press the hollow rubber ring 43, and the hollow rubber ring 43 drives the monitoring housing 41 to be fixed at the same time. At this time, the rapid installation of the monitoring component 4 can be completed. When the monitoring component 4 is protected, after the hollow rubber ring 43 is squeezed, the gas inside the hollow rubber ring 43 enters the gas storage tank 442 through the inner channel 445 opened on the inner side of the cylinder 443. At this time, the gas inside the gas storage tank 442 expands, and the cylinder 443 moves. Under the sealing effect of the silicone ring 444, the gas inside the cylinder 443 and the gas storage shell 441 is prevented from flowing out. The gas storage shell 441 drives the protective plate 46 to move. The protective plate 46 plays a role in protecting the monitoring shell 41. At the same time, under the action of the air pressure in the gas storage tank 442, it plays a certain buffering role.

The monitoring device based on the interface of an oil extraction manifold assembly according to claim 6, characterized in that: The glass column (51) has a scale at one end, the hydraulic groove (52) is connected to the inside of the connecting through hole (53), one side of the glass column (51) is fixedly connected to one side of the liquid guide tube (8), and the connecting through hole (53) is connected to the inside of the airbag (7) through the liquid guide tube (8).

8. The monitoring device based on the interface of an oil extraction manifold assembly according to claim 7, characterized in that: The hydraulic groove (52) is cylindrical in shape. The outer side of the rubber column (59) is in contact with the inner side of the hydraulic groove (52) opened by the glass column (51). A baffle (57) is fixedly connected inside the hydraulic groove (52) opened by the glass column (51).

9. A monitoring method based on the monitoring device at the interface of an oil extraction manifold assembly as described in claim 8, characterized in that: S1: To detect leaks in the manifold assembly (1) without using electrical equipment, hydraulic oil is filled into the monitoring housing (41) through the filling hole (47) at the front end. The solenoid valve (48) is opened. When the monitoring housing (41) is full of hydraulic oil, the hydraulic oil squeezes the silicone seal (45). Under the pressure, the silicone seal (45) moves and drives the first spring telescopic rod (49) to extend. Under the tension of the first spring telescopic rod (49), the silicone seal (45) is kept in contact with the filling hole (47). The diameter of the silicone seal (45) is smaller than the diameter of the filling hole (47). When the silicone seal (45) moves away from the contacted filling hole (47), the hydraulic oil enters the hydraulic groove (52) from the filling hole (47). When the hydraulic oil fills to the scale line of the glass column (51), After the lowest point, the hydraulic oil comes into contact with the buoy ball (54), and the filling is completed. When the oil leaks inside the manifold assembly (1), the hydraulic oil gradually enters the hydraulic groove (52). After the buoy ball (54) comes into contact with the hydraulic oil, the buoy ball (54) moves. The movement of the buoy ball (54) can be driven by the sliding roller (58) to move the rubber column (59). When the hydraulic oil enters the hydraulic groove (52), the sliding roller (58) drives the disc (56) to move upward. The disc (56) drives the second spring telescopic rod (55) to extend. Under the elastic force of the second spring telescopic rod (55), when the rubber column (59) moves away from the connecting through hole (53), the hydraulic oil enters the airbag (7) through the connecting through hole (53) and the guide pipe (8). At this time, the oil leakage of the manifold assembly (1) can be monitored by the scale on the glass column (51). S2: When the monitoring component (4) is installed quickly, the two monitoring housings (41) are fitted together. The right-angle pressure plate (42) fixed on one side of the monitoring housing (41) is aligned with the ladder groove (35). The servo motor (31) drives the double threaded rod (32) to rotate. The double threaded rod (32) drives the inner threaded plate (33) connected by the outer spiral to move. According to the shape of the double threaded rod (32), the two inner threaded plates (33) simultaneously drive the moving folding plate (34) to move closer to the right-angle pressure plate (42). When the right-angle pressure plate (42) enters the interior of the ladder groove (35), under the pressure of the moving folding plate (34), the rubber sheet in the middle of the moving folding plate (34), the right-angle pressure plate (42) at the left and right ends will come into close contact. The right-angle pressure plate (42) will drive the monitoring housing (41) to move closer at the same time. The two monitoring housings (41) will press against the hollow rubber ring (43) at the same time. The hollow rubber ring (43) will drive the monitoring housing (41) to be fixed at the same time. At this time, the rapid installation of the monitoring component (4) can be completed. S3: When the monitoring component (4) is protected, after the hollow rubber ring (43) is squeezed, the gas inside the hollow rubber ring (43) enters the gas storage tank (442) through the inner channel (445) opened on the inner side of the cylinder (443). At this time, the gas inside the gas storage tank (442) expands, the cylinder (443) moves, and the gas storage shell (441) drives the protective plate (46) to move.
