Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The test device in the present invention includes: a conveying component including a first conveying unit and a second conveying unit, the first conveying unit is used to communicate with the first crossing channel of the electro-hydraulic crosser, and the second conveying unit is used to communicate with the second crossing channel of the electro-hydraulic crosser; because the electro-hydraulic crosser mainly includes the transmission of electrical signals and liquid signals, and the first conveying unit can transmit electrical signals into the first crossing channel, and the second conveying unit can transmit liquid signals into the second transmission channel, the first conveying unit and the second conveying unit can simulate the real operation state of the electro-hydraulic crosser; and the regulating component can adjust the working parameters of the electro-hydraulic crosser, and the working parameters include the temperature and pressure in the first crossing channel and the second crossing channel, which means that the present invention can simulate the environment in which the first crossing channel and the second crossing channel are located when the electro-hydraulic crosser is in operation through the regulating component; for example, the working state of the electro-hydraulic crosser at 1500 meters underwater is simulated, and pressure, temperature and other tests are performed under the state of 10000psi, so as to reduce the huge losses caused by the failure or defect of the electro-hydraulic crosser not being detected, resulting in damage to the electro-hydraulic crosser during operation.

[0033] Moreover, the guide assembly in the present invention includes a first guide member and a second guide member provided on the electro-hydraulic transducer, a third guide member provided on the first conveying unit, and a fourth guide member provided on the second conveying unit. The first guide member and the third guide member form a first guide pair, and the second guide member and the fourth guide member form a second guide pair. The first guide pair can maintain a stable connection between the first conveying unit and the first crossing channel, and maintain stable transmission of the electrical signal. The second guide pair can maintain a stable connection between the second conveying unit and the second crossing channel, and maintain stable transmission of the liquid signal, thereby reducing the problem of unstable electrical signal transmission state and / or liquid signal state caused by unstable connection between the first conveying assembly and the first crossing channel, and / or unstable connection between the second conveying assembly and / or the second crossing channel, so that the unstable electrical signal and liquid signal transmission state is mainly caused by the defects of the electro-hydraulic transducer itself, thereby improving the accuracy of the test device in the present invention in detecting quality or performance defects of the electro-hydraulic transducer; in this way, possible defects in the quality and performance of the electro-hydraulic transducer will be discovered before the electro-hydraulic transducer is operated, and then the operator can make up for the defects of the electro-hydraulic transducer, thereby reducing safety accidents caused by defects in performance, quality, etc. during the operation of the electro-hydraulic transducer.

[0034] The first crossing pipe and the second crossing pipe are both arranged along the axial direction of the electro-hydraulic crosser. The delivery assembly includes a first delivery unit capable of delivering an electrical signal into the first crossing pipe, and a second delivery unit capable of delivering a liquid signal into the second crossing pipe; the delivery assembly is not limited to the above structure, and a delivery unit capable of transmitting other types of signals into the crossing pipe may be arranged as required, for example, a delivery unit capable of transmitting a gas signal, an optical signal, or a multi-physical field and environmental signal into the crossing pipe may be arranged.

[0035] The first conveying unit includes a first conveying member and an electric cross-connector fastener, the second end of the electric cross-connector fastener is connected to the first input port 6 of the first crossing channel, the first conveying member is sequentially penetrated through the electric cross-connector fastener 4 and the first crossing channel along the first feeding direction, and the first conveying member is used to transmit electrical signals to the first crossing channel; the first conveying member can be specifically a structure such as a cable that can transmit electrical signals, and the two ends of the cable are respectively connected to the electrical signal sending end and the electrical signal receiving end, and the electrical cross-connector 4 is specifically a structure that is sleeved outside the first conveying member and connected to the first input port 6, such as a pipe.

[0036] The second conveying unit includes a second conveying member and a liquid-through-fastener 3 arranged in sequence along the second feeding direction. The first end and the second end of the liquid-through-fastener 3 are respectively connected to the second conveying member and the second input port 7 of the second crossing channel. The second conveying member is used to convey a liquid signal into the second crossing channel. The second conveying member is specifically a structure for conveying the working medium when the electro-hydraulic crosser is in operation into the second crossing channel, such as a pump. The first end of the second conveying member is connected to a storage box storing the working medium, and the second conveying member can transfer the working medium in the storage box to the second crossing channel through the liquid-through-fastener 3. The electric-through-fastener 4 is specifically a structure that connects the second input port 7 with the second conveying member, such as a pipeline. When the second conveying member conveys the working medium into the second crossing channel, the transmission of the liquid signal is realized. The second end of the electric-through-fastener 4 can adopt a plug-in port. Similarly, the second end of the liquid-through-fastener 3 can also adopt a plug-in port. Alternatively, the second end of the electrical through-fastener 4 can be fixed to the first input port 6 by fasteners such as bolts, and the second end of the liquid through-fastener 3 can also be fixed to the second input port 7 by fasteners such as bolts.

[0037] The regulating component includes a structure capable of providing a working medium with a certain pressure and / or a certain temperature to the first conveying unit and the second conveying unit, such as a storage tank storing the working medium. A temperature regulating device, such as a heating wire and / or a cooling water jacket, can be set in the storage tank or between the storage tank and the first conveying unit and the second conveying unit to regulate the temperature of the working medium. The pressure regulating device can be set between the storage tank and the first conveying unit and the second conveying unit. The pressure regulating device includes a pressure pump and / or a pressure reducing valve to achieve pressure regulation of the working medium. The working medium with the required temperature and pressure is transported to the first crossing channel and the second crossing channel through the temperature regulating device and the pressure regulating device, thereby creating a real operating environment for the first crossing channel and the second crossing channel. Alternatively, if the working conditions require, the corresponding temperature and pressure environment can also be created outside the electro-hydraulic transponder through the above-mentioned temperature regulating device and the pressure regulating device, thereby creating the environment in which the electro-hydraulic transponder is in operation. In addition, the regulating component can also include a driving device capable of driving the electro-hydraulic transponder to rotate, and the electro-hydraulic transponder is driven to rotate through a driving device such as a servo motor, thereby simulating the external vibration to which the electro-hydraulic transponder is subjected during operation.

[0038] The first guide member and the second guide member may specifically be guide rods or guide blocks provided on the end surface of the electro-hydraulic crosser, and the fourth guide member may specifically be a plurality of third guide holes 9, for example 3, provided on the second end of the liquid crossing snap-fit ​​device 3, and the third guide holes 9 cooperate with the guide blocks or guide rods, so that the liquid crossing snap-fit ​​device 3 can be installed at the second input port 7 only when it is aligned with the second crossing channel; similarly, the third guide member may specifically be a plurality of third guide holes 9 provided on the second end of the electric crossing snap-fit ​​device 4, and the third guide holes 9 cooperate with the guide blocks or guide rods.

[0039] Alternatively, the first guide member and the second guide member may be specifically the first guide hole and the second guide hole provided on the end surface of the electro-hydraulic crosser, respectively. The first guide hole and the second guide hole are both provided along the axial direction of the electro-hydraulic crosser, the first guide hole is connected to the first crossing channel, and the second guide hole is connected to the second crossing channel. In this case, the first guide hole can be understood as the first input port 6, that is, the two are the same structure, and the second guide hole can be understood as the second input port 7. The third guide member is specifically the shape of the second end of the electric crossing fastener 4, that is, the second end of the electric crossing fastener 4 has a guide surface that matches the first input port 6; the fourth guide member is specifically the shape of the second end of the liquid crossing fastener 3, that is, the second end of the liquid crossing fastener 3 has a guide surface that matches the second input port 7.

[0040] like Figure 1 to Figure 6 As shown, the first input port 6 and the second input port 7 are located at the same end of the electro-hydraulic crosser; a plurality of second cross-channels are arranged along the circumference of the electro-hydraulic crosser with the first cross-channel as the center; and / or, the detection component includes an observation hole 8 or a pressure gauge connected to the second cross-channel. When the second cross-channel is connected to the observation hole 8, if the second conveying member conveys the working medium into the second cross-channel and there is a leakage point in the electro-hydraulic crosser, the working medium will flow out from the observation hole 8 or the area where the leakage point is located, so that the operator can directly observe it; and / or, the second conveying member is a cable, and the detection component includes a voltmeter and / or an ammeter connected to the cable. The voltmeter and / or the ammeter connected to the second conveying member is used to determine whether the electrical signal transmission is abnormal.

[0041] The test device includes a sealing assembly, which includes a first sealing unit disposed between the electrical crossing snapper 4 and the first crossing channel, and a second sealing unit disposed between the liquid crossing snapper 3 and the second crossing channel. The first sealing unit and the second sealing unit may be metal seals and / or gap seals and / or sealing rings. The first sealing unit may be disposed between the second end of the electrical crossing snapper 4 and the first input port 6, and / or between the electrical crossing snapper 4 and the side wall of the first crossing channel; the second sealing unit may be disposed between the second end of the liquid crossing snapper 3 and the second input port 7, and / or between the liquid crossing snapper 3 and the side wall of the second crossing channel.

[0042] like Figure 1 to Figure 6As shown, the second end of the liquid-through fastener 3 is tapered, and the second input port 7 is tapered. The second end of the liquid-through fastener 3 and the second input port 7 form a first sealing pair, which means that when the second end of the liquid-through fastener 3 enters the second input port 7 to a certain extent, the second end of the liquid-through fastener 3 will be against the second input port 7. For example, the inclination angle of the second end of the liquid-through fastener 3 is 60°, and the inclination angle of the second input port 7 is 59°. A first sealing member is provided between the second end of the liquid-through fastener 3 and the second input port 7. The first sealing member can specifically be a sealing ring. At this time, the first sealing unit includes a first sealing pair and a first sealing member.

[0043] Similarly, the second end of the electric crossing snap device 4 is conical, and the first input port 6 is conical. The second end of the electric crossing snap device 4 and the first input port 6 form a second sealing pair, which means that when the second end of the electric crossing snap device 4 enters the first input port 6 to a certain extent, the second end of the electric crossing snap device 4 will be against the first input port 6. For example, the inclination angle of the second end of the electric crossing snap device 4 is 60°, and the inclination angle of the first input port 6 is 59°, and a second sealing member is provided between the second end of the electric crossing snap device 4 and the first input port 6. The second sealing member can specifically be a sealing ring. At this time, the second sealing unit includes a second sealing pair and a second sealing member.

[0044] The electro-hydraulic crosser docking profile 1 in the attached drawings of the present invention refers to a structure set in imitation of the docking profile of a real electro-hydraulic crosser. In this way, there is no need to imitate the structure of the entire electro-hydraulic crosser, which reduces the experimental cost. The first conveying unit and the second conveying unit are both located in the test equipment 2. The test equipment 2 is an electro-hydraulic crosser FAT test equipment. The test equipment 2 is manufactured in imitation of the structure of the equipment such as the Christmas tree assembly and the tubing hanger assembly that are docked with the electro-hydraulic crosser. The test equipment 2 is provided with a structure of liquid signals on the Christmas tree and the tubing hanger that can transmit electrical signals to the electro-hydraulic crosser. The end face of the test equipment is connected to the electro-hydraulic crosser docking profile 1 by fasteners such as bolts, and is positioned by positioning pins. The side of the test equipment 2 is provided with a mounting hole 5 for inserting a temperature sensor, and the temperature of the environment in which the electro-hydraulic crosser is located can be detected by the temperature sensor. In the present invention, the liquid cross-fastener and the electric cross-fastener can be set separately or as a whole.

[0045] Furthermore, the guide assembly of the present invention also includes an angle sensor, a displacement sensor, a moving unit, a controller, an angle sensor, and the displacement sensor is arranged on the liquid-through fastener 3. The angle sensor, the displacement sensor, and the moving unit are all connected to the controller signal; when the operator or the controller determines that there is an assembly error between the liquid-through fastener 3 and the second input port 7, such as an axial or radial deviation, based on the feedback of the angle sensor and the displacement sensor, the controller starts the moving unit, and under the action of the moving unit, the liquid-through fastener 3 moves in the first direction, that is, the direction of reducing the assembly error; for example, if the displacement sensor detects that the liquid-through fastener 3 has not moved the required distance toward the second input port 7, the controller or the operator starts the moving unit, and the moving unit drives the liquid-through fastener 3 to move toward the second input port 7 until the required distance is reached. At this time, the first direction is the axial direction of the electro-hydraulic crosser; if the angle sensor or the camera finds that the liquid-through fastener 3 and the second input port 7 are not coaxially arranged, the controller or the operator starts the moving unit, and the moving unit drives the liquid-through fastener 3 to move along the radial direction of the electro-hydraulic crosser. At this time, the first direction is the radial direction of the electro-hydraulic crosser. The mobile unit may specifically be an XYZ high-precision mobile platform, also known as a three-coordinate high-precision mobile platform, which is a prior art and the specific structure will not be described in detail.

[0046] In addition, the present invention provides a flexible layer in the second input port 7. The flexible layer may be made of an elastic material such as rubber. The flexible layer allows a certain displacement deviation between the second end of the liquid-through-fastener 3 and the second input port 7, and / or a gap between the second input port 7 and the second end of the liquid-through-fastener 3. This allows the second end of the liquid-through-fastener 3 to move a certain distance in the second input port 7 without vibrating when it is subjected to external vibration.

[0047] The test device also includes an alarm component; the alarm component and the detection component are connected to the controller signal. When the controller determines that the operating parameters of the electro-hydraulic transducer exceed the threshold value based on the feedback of the detection component, the alarm component starts to alarm. The alarm component can be a sound alarm or an audible and visual alarm; the threshold value is the critical value of the operation of the electro-hydraulic transducer. When the operating parameter exceeds the threshold value, the electro-hydraulic transducer is prone to damage; in this way, the alarm component can remind the operator to adjust the adjustment component in time to prevent the electro-hydraulic transducer from being damaged during the test.
