Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1:

[0034] Refer to Figures 1 to 5, which shows the composition scheme of the underwater oil equipment pressure testing device in this example, specifically showing the overall three-dimensional structure and internal structure of this device.

[0035] Combined with Figures 1 to 3 As shown, the underwater oil equipment pressure testing device given in this example specifically includes a test rack 1, a moving component 7, and a test pipeline 15. Two chutes 3 are provided at the top of the test rack 1. A motor 4 is fixedly installed on the left side of the test rack 1. A bidirectional lead screw 5 is fixedly installed on the output shaft of the motor 4. An installation component 8 is fixedly installed on the top of the moving component 7, and a limiting component 9 is provided on the top of the installation component 8.

[0036] In some embodiments of this example, as Figure 4 shown, the moving component 7 in this example includes a fixing plate 701 provided at the top of the test rack 1. A positioning groove 702 for positioning is provided at the top of the fixing plate 701. A slider 703 slidably connected to the chute 3 is fixedly installed at the bottom of the fixing plate 701. A threaded sleeve 704 threadedly connected to the bidirectional lead screw 5 is fixedly installed at the bottom of the fixing plate 701.

[0037] In the moving component 7 arranged like this, through the design of the slider 703 and the threaded sleeve 704, the motor 4 can be turned on by controlling the switch 2. Subsequently, when the motor 4 rotates, it can drive the bidirectional lead screw 5 to rotate, so that the bidirectional lead screw 5 drives the threaded sleeve 704 to move the slider 703 left and right in the chute 3, so as to facilitate adjusting the distance between them according to the length of the pipeline.

[0038] In some embodiments of this example, as Figure 5 shown, the installation component 8 in this example includes an installation plate 801 fixedly installed on the top of the moving component 7. A first positioning bolt 802 for positioning is fixedly installed on the top of the installation plate 801. A fixing hoop 803 is fixedly installed on the top of the installation plate 801. Positioning plates 804 are fixedly installed on both sides of the fixing hoop 803. An installation groove 805 is provided at the top of the positioning plate 804. A plurality of equally spaced first anti-slip sleeves 806 are fixedly installed on the inner wall of the fixing hoop 803.

[0039] In some embodiments of this example, as Figure 5 shown, the limiting component 9 in this example includes a limiting sleeve 901 fixedly installed on the top of the installation component 8. Second positioning bolts 902 are provided on both sides of the top of the limiting sleeve 901. A plurality of equally spaced second anti-slip sleeves 903 are fixedly installed inside the limiting sleeve 901. The test pipeline 15 is located between the fixing hoop 803 and the second anti-slip sleeves 903.

[0040] On this basis, in the installation component 8 of this embodiment, the first positioning bolt 802 penetrates through the mounting plate 801 and extends into the interior of the moving component 7, and the second positioning bolt 902 penetrates through the limiting sleeve 901 and extends to the outside of the installation groove 805. With such a setting, through the design of the first positioning bolt 802, when the installation component 8 is placed above the moving component 7, the installation component 8 can be quickly installed through the first positioning bolt 802. Subsequently, the test pipeline 15 is placed in the installation component 8, and then the limiting component 9 is placed. By rotating the second positioning bolt 902, the test pipeline 15 can be fixed to prevent displacement during the test.

[0041] As a further preferred setting, in the installation component 8 of this embodiment, the first anti-slip sleeve 806 and the second anti-slip sleeve 903 in the limiting component 9 are made of rubber anti-slip sleeves, and the fixing hoop 803 and the limiting sleeve 901 are in a "C"-shaped structure. In this way, through the rubber first anti-slip sleeve 806 and the second anti-slip sleeve 903, when the test pipeline 15 is placed in the "C"-shaped fixing hoop 803 and the limiting sleeve 901, the rubber first anti-slip sleeve 806 and the second anti-slip sleeve 903 can be made to contact the test pipeline 15, thereby increasing their contact area and preventing rotation during the test.

[0042] Embodiment 2:

[0044] Combined with Figures 2 to 5 As shown, in this embodiment, for the installation component 8 and the limiting component 9, two identical sets are respectively provided, and each set of the installation component 8 and the limiting component 9 has two identical ones. Each set of the installation component 8 and the limiting component 9 is symmetrically distributed about the center line of the test rack 1. With such a setting, through the design of the two sets of installation components 8 and limiting components 9, the two test pipelines 15 can be fixedly clamped, which is convenient for testing the two test pipelines 15 during the test and can improve the test efficiency.

[0045] In this embodiment, a dust-proof plate 10 is further fixedly installed at the rear side of the top of the test rack 1 to improve the cleanliness during the use of the entire device.

[0046] Combined with Figure 2 As shown, in this embodiment, a fixing frame 11 is further fixedly installed at the top of the test rack 1. A cylinder 12 is fixedly installed at the top of the fixing frame 11. A limiting plate 13 is fixedly installed on the output shaft of the cylinder 12. A limiting groove 14 is opened on the outer side of the limiting plate 13, and the limiting groove 14 is in a "C"-shaped structure. With such a setting, when testing the connection of the oil pipeline, the cylinder 12 can be activated by controlling the switch 2, and then the limiting plate 13 is made to be at the same height as the installation component 8 to support the connection and ensure that it is not easy to move during the process of testing the connection.

[0047] Combined Figures 1 to 3 As shown, in this embodiment, a control switch 2 is further fixedly installed on the front side of the test stand 1. Mounting seats 6 for positioning the bidirectional lead screw 5 are fixedly installed on both sides of the top of the test stand 1. The motor 4 and the control switch 2 are electrically connected.

Subsequently, the test pipeline 15 is placed in the installation component 8, and then the limiting component 9 is placed. By rotating the second positioning bolt 902, the test pipeline 15 can be fixed to prevent displacement during the test;

[0051] Through the rubber first anti-slip sleeve 806 and the second anti-slip sleeve 903, after the test pipeline 15 is placed in the "C"-shaped fixing hoop 803 and the limiting sleeve 901, the rubber first anti-slip sleeve 806 and the second anti-slip sleeve 903 can be in contact with the test pipeline 15, thereby increasing the contact area and preventing rotation during the test;

[0052] Through the design of two sets of installation components 8 and limiting components 9, two test pipelines 15 can be fixedly clamped, which is convenient for testing the two test pipelines 15 during the test and can improve the test efficiency. When testing the connection of the oil pipeline, the cylinder 12 can be turned on through the control switch 2.
