The cross-section of the pressure test platform 2 is circular, and a pressure test port 4 is fixedly penetrated on the pressure test platform 2 in the vertical direction. One end of the pressure test port 4 is located below the pressure test platform 2 for external pressure test pump pipeline, and the other end is located above the pressure test platform 2 and is connected to a quick-install pressure test head 5, which is used for sealing and plugging with the internal blowout prevention tool.

[0025] Reference Figure 2 The cross section of the gland 3 is circular, the gland 3 is fixedly sleeved on the upper end of the second fixed column 103, the gland 3 is located above the pressure test platform 2, the quick-install pressure test head 5 is located between the gland 3 and the pressure test platform 2, and the gland 3 is plugged with a quick-install pressure plate for covering and pressing the end of the internal blowout prevention tool away from the quick-install pressure test head 5.

[0026] When in use, the pressure test end of the internal blowout prevention tool is plugged into the quick-install pressure test head 5, and the quick-install pressure plate is plugged into the pressure cover 3, so that the quick-install pressure plate covers and presses the end of the internal blowout prevention tool away from the quick-install pressure test head 5, and then the pressure test pump pipeline connected to the pressure test port 4 is opened to perform pressure test on the internal blowout prevention tool. The internal blowout prevention tool is fixed by the quick-install pressure plate and the quick-install pressure test head 5 for sealing test. On the one hand, there is no need to connect various threaded joints, which simplifies the operation steps and helps to improve the pressure test efficiency; on the other hand, during the pressure test, the quick-install pressure plate covers and presses the end of the internal blowout prevention tool away from the quick-install pressure test head 5, which helps to avoid the damage caused by the accidental release of pressure at the end of the internal blowout prevention tool away from the quick-install pressure test head 5. At the same time, the pressure test pump pipeline is connected to the pressure test port 4, and there is no need to disassemble the pressure test pump pipeline back and forth, which reduces the damage to the pressure test pump pipeline.

[0027] Reference Figure 2 There are multiple pressure test ports 4 fixedly penetrated on the pressure test platform 2, and the multiple pressure test ports 4 are evenly spaced along the circumference of the pressure test platform 2. In the embodiment of the present application, four pressure test ports 4 are provided. In other embodiments, the number of pressure test ports 4 can be set according to actual needs. The quick-release pressure plate corresponds to the pressure test port 4 one by one. Integrating multiple pressure test ports 4 on the pressure test platform 2 helps to test multiple internal blowout prevention tools at the same time, greatly improving efficiency.

[0028] Reference Figure 2, the quick-install pressure test head 5 is plugged into the corresponding pressure test port 4, and a first sealing ring 7 for improving the sealing between the quick-install pressure test head 5 and the pressure test port 4 is fixed in the pressure test port 4. Plugging the quick-install pressure test head 5 into the pressure test port 4 helps to replace the adapted quick-install pressure test head 5 according to the specification type of the internal blowout preventer tool, thereby helping to realize the simultaneous pressure testing of multiple internal blowout preventers of multiple types and sizes, solving the problem that the sealing test of internal blowout preventers of a single connection type and a single size can only be performed; improving the sealing by the first sealing ring 7 helps to ensure the accuracy and safety of the pressure test; the setting of the quick-install pressure test head 5 helps to realize the rapid installation of the internal blowout preventer tool without the need to connect with various threads, reducing manpower and improving efficiency.

The end of the pressure test connector 51 used to be inserted into the pressure test port 4 is fixed with a third sealing ring 18, and the third sealing ring 18 is used to further enhance the sealing between the pressure test connector 51 and the pressure test port 4.

[0030] Reference Figure 2 The boss 52 is integrally formed and sleeved outside the pressure test connector 51. When the pressure test connector 51 is plugged into the pressure test port 4, the boss 52 abuts against the upper surface of the pressure test port 4; the side of the boss 52 away from the pressure test port 4 is used to abut against the end face of the internal blowout preventer tool.

[0031] The quick-install pressure test head 5 is connected to the internal blowout prevention tool by a sealed plug-in method, which can realize simple and quick installation of the internal blowout prevention tool. At the same time, it can avoid the possibility of vibration impact or surface damage to the internal blowout prevention tool body when the internal blowout prevention tool is connected to the thread, and the possibility of impact damage and surface bite to the internal blowout prevention tool caused by the use of hammers and pipe clamps during connection, thereby helping to achieve non-destructive pressure testing. The setting of the boss 52 helps to enhance the sealing connection effect of the internal blowout prevention tool, and at the same time, protect the pressure test port 4.

[0032] Reference Figure 2The gland 3 is provided with a notch 6 for plugging with the quick-install pressure plate. The notch 6 corresponds to the quick-install pressure plate one by one. The notch 6 is aligned with the corresponding pressure test port 4, and the cross-sectional area of ​​the notch 6 is larger than the cross-sectional area of ​​the internal blowout prevention tool. The plug-in direction of the quick-install pressure plate is set in the horizontal direction. After the internal blowout prevention tool is installed, the quick-install pressure plate is horizontally inserted into the corresponding position. The quick-install pressure plate covers and presses the end of the internal blowout prevention tool away from the quick-install pressure test head 5, realizing simple and quick installation. During the pressure test, the damage caused by the accidental release of pressure at the other end of the internal blowout prevention tool can be eliminated.

[0033] Reference Figure 2 , wherein the quick-loading pressure plate includes an upper limit plate 9, a connecting column 10 and a lower limit plate 11, the upper limit plate 9, the connecting column 10 and the lower limit plate 11 are fixedly connected in sequence from top to bottom, and the cross-sections of the upper limit plate 9 and the lower limit plate 11 are both larger than the cross-section of the notch 6 to completely cover the notch 6; the cross-section of the connecting column 10 is circular, the cross-section of the connecting column 10 is smaller than the cross-section of the notch 6, and the diameter of the connecting column 10 is equal to the width of the notch 6, so that the quick-loading pressure plate is not easy to shake after being plugged into the pressure cover 3; the length of the connecting column 10 is equal to the thickness of the pressure cover 3, and the lower limit plate 11 is used to cover and press the end of the internal blowout prevention tool away from the quick-loading pressure test head 5; when the connecting column 10 is located in the notch 6, the lower limit plate 11 abuts against the side of the pressure cover 3 close to the pressure test platform 2, and the upper limit plate 9 abuts against the side of the pressure cover 3 away from the pressure test platform 2. In order to facilitate sliding of the upper limit plate 9 , a paddle 23 is fixed to a side of the upper limit plate 9 away from the lower limit plate 11 .

[0034] After the internal blowout prevention tool is installed on the quick-install pressure test head 5, the connecting column 10 of the quick-install pressure plate is aligned with the notch 6, and then the quick-install pressure plate is moved horizontally in the direction close to the notch 6, so that the connecting column 10 of the quick-install pressure plate moves into the notch 6, and the lower limit plate 11 abuts against the side of the pressure cover 3 close to the pressure test platform 2, and the upper limit plate 9 abuts against the side of the pressure cover 3 away from the pressure test platform 2, and then the lower limit plate 11 gradually abuts against the end of the internal blowout prevention tool away from the quick-install pressure test head 5, thereby fixing and sealing the internal blowout prevention tool, so as to eliminate the damage caused by accidental release of pressure at the end of the internal blowout prevention tool away from the quick-install pressure test head 5 during the pressure test.

[0035] Reference Figure 2A plurality of first support legs 19 are fixed to the first fixed column 102. The first support legs 19 are located below the pressure test platform 2. The plurality of first support legs 19 are spaced apart along the circumference of the pressure test platform 2. In the embodiment of the present application, four first support legs 19 are provided. The first support legs 19 are fixed to the bottom wall of the pressure test platform 2, thereby helping to support the pressure test platform 2 and enhancing the structural stability of the pressure test platform 2. A plurality of second support legs 20 are fixed to the second fixed column 103. The second support legs 20 are located below the gland 3. The plurality of second support legs 20 are spaced apart along the circumference of the gland 3. In the embodiment of the present application, four second support legs 20 are provided. The second support legs 20 are fixed to the bottom wall of the gland 3, thereby helping to support the gland 3 and enhancing the structural stability of the gland 3.

[0036] Reference Figure 2 , a plurality of tensioning screws 21 are provided between the gland 3 and the pressure test platform 2, and nuts 22 are threadedly connected at both ends of the tensioning screws 21, the nut 22 at one end abuts against the side of the gland 3 away from the pressure test platform 2, and the nut 22 at the other end abuts against the side of the pressure test platform 2 away from the gland 3. In the embodiment of the present application, four tensioning screws 21 are provided along the circumference of the pressure test platform 2, and the cooperation between the tensioning screws 21 and the nuts 22 helps to improve the connection stability between the pressure test platform 2 and the gland 3, and ensure the safety of the pressure test. In order to further enhance the structural stability, a locking nut (not shown in the figure) can be threadedly connected to the tensioning screw 21, and the locking nut abuts against the bottom wall of the gland 3 to ensure that the gland 3 is not easy to move when the internal blowout preventer leaks.

[0037] The implementation principle of Example 1 of the present application is as follows: when in use, the quick-install pressure test head 5 adapted to the internal blowout prevention tool to be tested is inserted into the pressure test port 4 until the boss 52 of the quick-install pressure test head 5 abuts against the upper surface of the pressure test port 4, and the quick-install pressure test head 5 and the pressure test port 4 are sealed and connected through the first sealing ring 7 and the third sealing ring 18, and then the internal blowout prevention tool to be tested is passed through the notch 6 so that the pressure test end is inserted into the corresponding quick-install pressure test head 5, until the end face of the internal blowout prevention tool abuts against the boss 52 of the quick-install pressure test head 5, and then the pressure test end is sealed and connected to the pressure test port 4 through the first sealing ring 7 and the third sealing ring 18. The second sealing ring 8 is sealedly connected with the sealing ring in the internal blowout prevention tool; then the connecting column 10 of the quick-loading pressure plate is aligned with the corresponding notch 6, and then the quick-loading pressure plate is horizontally moved in the direction close to the notch 6, so that the connecting column 10 of the quick-loading pressure plate is moved into the notch 6, and the lower limit plate 11 is abutted against the side of the pressure cover 3 close to the pressure test platform 2, and the upper limit plate 9 is abutted against the side of the pressure cover 3 away from the pressure test platform 2, and then the lower limit plate 11 is abutted against the end of the internal blowout prevention tool away from the quick-loading pressure test head 5, thereby fixing and sealing the internal blowout prevention tool.

[0038] Then, the pressure test pump pipeline connected to the pressure test port 4 is opened to realize pressure test on the internal blowout preventer tool. During the pressure test, the internal blowout preventer tool does not need to be connected to various threaded joints, which simplifies the operation steps. This not only helps to improve the pressure test efficiency, but also can perform pressure tests on internal blowout preventer tools of different types and sizes without damaging the internal blowout preventer tool easily. At the same time, during the pressure test, the quick-install pressure plate covers and presses the end of the internal blowout preventer tool away from the quick-install pressure test head 5, which helps to avoid damage caused by accidental release of pressure at the non-pressure test end of the internal blowout preventer tool.

[0039] Embodiment 2: Reference Figure 3 and Figure 4 The difference between the embodiment of the present application and embodiment 1 is that the quick-release pressure plate includes a clamping plate 12 and an abutment block 13. An opening 14 for the internal blowout prevention tool to pass through is provided on one side of the clamping plate 12 close to the notch 6, so that the clamping plate 12 is U-shaped, and the cross-section of the opening 14 is larger than the cross-section of the internal blowout prevention tool and smaller than the cross-section of the notch 6; the thickness of the clamping plate 12 is larger than the thickness of the pressure cover 3, and an inserting groove 15 for plugging with the pressure cover 3 is provided on the outer edge of the clamping plate 12. The thickness of the inserting groove 15 is equal to the thickness of the pressure cover 3, and the upper wall of the inserting groove 15 is used to abut against the upper surface of the pressure cover 3, and the lower wall of the inserting groove 15 is used to abut against the lower surface of the pressure cover 3, so that when the inserting groove 15 of the clamping plate 12 is inserted into the notch 6 of the pressure cover 3, the clamping plate 12 can be clamped on the pressure cover 3 to limit the up and down movement.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The abutment block 13 is slidably arranged on the clamping plate 12, and the abutment block 13 is aligned with the corresponding opening 14. The sliding direction of the abutment block 13 is perpendicular to the plane where the opening 14 is located. The abutment block 13 is used to cover and press the end of the internal blowout prevention tool away from the quick-install test pressure head 5. The cross-section of the abutment block 13 is larger than the cross-section of the internal blowout prevention tool, and the cross-section of the abutment block 13 is smaller than the cross-section of the opening 14. The clamping plate 12 is provided with an adjusting member for adjusting the sliding of the abutment block 13.

[0041] Reference Figure 3 and Figure 4 In order to facilitate the adjustment of the abutment block 13 to slide toward or away from the clamping plate 12, the adjusting member includes a screw rod 16. Two screw rods 16 are relatively arranged. The two screw rods 16 are rotatably arranged on the opposite sides of the clamping plate 12. The rotation axis of the screw rod 16 is parallel to the sliding direction of the abutment block 13. Connecting blocks 17 are fixedly arranged on the opposite sides of the abutment block 13. The connecting blocks 17 correspond to the screw rods 16 one by one. The connecting blocks 17 are threadedly sleeved on the corresponding screw rods 16.

[0042] Reference Figure 3 and Figure 4The thickness of the abutment block 13 is greater than that of the clamping plate 12 , and the connecting block 17 is located on a side of the abutment block 13 away from the clamping plate 12 , so that the abutment block 13 can pass through the opening 14 to be suitable for internal blowout prevention tools of different types and sizes.

[0043] Reference Figure 4 and Figure 5 , a slider 25 is slidably connected to one side of the clamping plate 12 close to the screw rod 16, the slider 25 corresponds to the screw rod 16 one by one, the sliding direction of the slider 25 is perpendicular to the rotation axis of the screw rod 16, the end of the screw rod 16 close to the clamping plate 12 is fixedly sleeved with a first gear 24, a second gear 26 is fixed on the slider 25, the first gear 24 is meshed with the corresponding second gear 26, and a spring 27 for pushing the slider 25 to slide in the direction close to the corresponding screw rod 16 is provided on the clamping plate 12, and the end of the spring 27 away from the clamping plate 12 is fixed on the corresponding slider 25. The slider 25 is pushed by the spring 27 to keep the second gear 26 and the corresponding first gear 24 in meshing state, thereby limiting the rotation of the screw rod 16, making it difficult for the abutment block 13 to move even after being under pressure, and trying to avoid the damage caused by the accidental release of pressure at the other end of the internal blowout prevention tool.

[0044] The implementation principle of Example 2 of the present application is as follows: after the internal blowout prevention tool is installed on the quick-install pressure test head 5, the slider 25 is slid in a direction away from the corresponding screw rod 16 to disengage the second gear 26 from the corresponding first gear 24, and then the screw rod 16 is rotated. The screw rod 16 drives the connecting block 17 to drive the abutment block 13 to slide in a direction close to or away from the clamping plate 12. According to the actual length of the internal blowout prevention tool, the abutment block 13 is moved to the desired position, and then the slider 25 is released. The slider 25 approaches the corresponding screw rod 16 under the elastic action of the spring 27, so that the first gear 24 is meshed with the second gear 26 to limit the rotation of the screw rod 16.

[0045] Then, align the opening 14 of the clamping plate 12 with the notch 6, so that the screw rod 16 is located below or above the clamping plate 12, and then move the clamping plate 12 horizontally in the direction of the notch 6, so that the insertion groove 15 on the clamping plate 12 is gradually engaged with the pressure cover 3, until the abutment block 13 abuts against the end of the corresponding internal blowout prevention tool away from the quick-install pressure test head 5 to cover and press it; since the clamping plate 12 cannot move up and down, the connecting block 17 cannot rotate on the screw rod 16, and the screw rod 16 will not rotate under the meshing action of the first gear 24 and the second gear 26, so that the abutment block 13 cannot move up and down, thereby ensuring the abutment effect on the internal blowout prevention tool, and realizing the ability to simultaneously test the pressure of internal blowout prevention tools of different lengths, thereby greatly expanding the scope of application.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
