[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a blowout preventer group pressure test pit protective cover device as Figure 1 shown, a pressure test assembly 1, the pressure test assembly 1 includes a pressure test pit 11, a protective cover placement plate 12 is fixed on one side of the pressure test pit 11, and slide rails 13 are detachably installed on both the protective cover placement plate 12 and the pressure test pit 11 and are used to move the protective cover structure 2. Among them, four groups of support frames are provided under the protective cover placement plate 12 to support the protective cover placement plate 12 to ensure the normal placement of the protective cover placement plate 12.

[0024] Preferably, two groups of slide rails 13 are provided, and the two groups of slide rails 13 are symmetrically arranged about the central axis of the pressure test pit 11, and four groups of limit holes are opened on the pressure test pit 11.

[0025] In the above solution, a staircase is fixed on one side of the pressure test pit 11 and the protective cover placement plate 12, which is convenient for staff to repair. The staff fixes the slide rail 13 with bolts, which is convenient for adjusting the position of the protective cover structure 2.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 5 shown, the protective cover structure 2 is placed on the pressure test assembly 1 and is used to assist in closing the pressure test pit 11. The protective cover structure 2 includes a protective cover assembly 21. A support and limit assembly 22 is fixed on the protective cover assembly 21 and is used to assist in limiting and supporting the protective cover assembly 21. Among them, the protective cover assembly 21 includes a first protective cover plate 211. The first protective cover plate 211 is rotatably connected to the second protective cover plate 213 through a hinge 212. The positions of the third protective cover 214 are telescopically adjusted through telescopic structures inside both the first protective cover plate 211 and the second protective cover plate 213.

[0027] Preferably, the first protective cover plate 211 and the second protective cover plate 213 have the same diameter. The telescopic structure in this application is a hydraulic cylinder, which is a prior art. A third protective cover 214 is slidably connected inside both the first protective cover plate 211 and the second protective cover plate 213. The hydraulic cylinder inside the first protective cover plate 211 and the second protective cover plate 213 drives the third protective cover 214 to move out of the first protective cover plate 211 or the second protective cover plate 213 through a hydraulic rod, so as to facilitate the subsequent auxiliary covering of pressure test pits 11 with different lengths, without the need to customize pit covers for each pressure test pit on site, increasing the practicality.

[0028] Preferably, photovoltaic panels are inlaid on the first protective cover plate 211 and the second protective cover plate 213. The photovoltaic panels convert solar energy into electrical energy and store it in a storage battery. The storage battery is inlaid inside the first protective cover plate 211 and the second protective cover plate 213. The storage battery converts alternating current into direct current to provide electrical energy for the entire device.

[0029] In the above solution, the staff rotates the second protective cover plate 213, and the second protective cover plate 213 lays flat the first protective cover plate 211 and the second protective cover plate 213 stacked together with the assistance of the hinge 212. The staff pushes the second protective cover plate 213, and the second protective cover plate 213 moves to the required position with the assistance of the lower slide rail 13. With the assistance of the hydraulic cylinder, the hydraulic rod drives the third protective cover 214 to move, and finally covers the pressure test pits 11 with different lengths, increasing the practicality.

[0030] As Figure 1 、 Figure 2 and Figure 4 As shown, the support and limit assembly 22 includes a support plate 221. The support plate 221 telescopically adjusts a limit fixing plate 222 through a telescopic structure. The limit fixing plate 222 is fixed with an anti-slip pad 223 to play an anti-slip role. Four groups of support and limit assemblies 22 are provided, and the four groups of support and limit assemblies 22 are symmetrically arranged about the central axis of the protective cover assembly 21;

[0031] Furthermore, a small camera module is inlaid on the third protective cover 214. The small camera module transmits the on-site video to a later control module, and the staff locates the limit concave holes opened on the pressure test pit 11 according to the situation displayed on the display screen in the control module, ensuring that the support and limit assembly 22 accurately enters the limit concave holes;

[0032] In the above solution, the hydraulic cylinder of the support plate 221 drives the anti-slip pad 223 on the limit fixing plate 222 to move downward through a hydraulic rod, and finally inlays it in the limit hole. The anti-slip pad 223 on the limit fixing plate 222 plays an anti-slip role.

[0033] Working principle: When using the pressure test pit protection cover device of the blowout preventer group, connect to the external power supply, place the protection cover structure 2 on the pressure test component 1 and cover the pressure test pit 11.

[0034] The orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only a simplified description for facilitating the description of the present utility model, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the protection scope of the present utility model.
