[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An ultra-high temperature and high pressure device for simulating high pressure and high temperature geological conditions includes:

[0008] The frame includes a top plate and a bottom plate arranged parallel to each other, and the top plate and the bottom plate are fixedly connected by multiple vertically arranged tie rods;

[0009] The pressure application mechanism includes an upper hydraulic cylinder and a lower hydraulic cylinder, wherein the upper hydraulic cylinder is disposed on the bottom surface of the top plate and the lower hydraulic cylinder is disposed on the top surface of the bottom plate;

A motor drives the take-up reel to rotate, thereby winding the first rope and pulling the second rope. With the cooperation of the first, second, and third guide rings, the second protective cover can be pulled up to facilitate sample placement. The motor, combined with the weight of the second protective cover, can unwind the first rope, allowing the second protective cover to descend and cover the pressure chamber.

[0018] Furthermore, the first protective cover, the second protective cover, and the third protective cover are all cylindrical and coaxially arranged.

[0019] Furthermore, the upper hydraulic cylinder and the lower hydraulic cylinder are coaxially arranged.

[0020] Furthermore, the upper hydraulic cylinder is coaxially arranged with the first protective cover, and the lower hydraulic cylinder is coaxially arranged with the third protective cover.

[0021] Furthermore, the outer diameter of the first protective cover is the same as the outer diameter of the third protective cover, and the inner diameter of the first protective cover is the same as the inner diameter of the third protective cover.

[0022] Furthermore, the pad has a first notch on the side near the pull rod that matches the shape of the outer circumference of the pull rod, and a second notch on the side near the protective mechanism that matches the shape of both the first and third protective covers.

[0023] Furthermore, the bottom of the second protective cover protrudes downward to form a guide portion, the inner diameter of which is the same as the inner diameter of the second protective cover, and the outer diameter of which gradually decreases from top to bottom.

[0024] Furthermore, the inner wall of the top of the third protective cover is provided with a positioning ring, and the guide portion presses against the positioning ring.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] (1) The present invention can be used to block splashed metal parts or metal fragments by setting a protective mechanism, so that the metal parts or metal fragments are difficult to splash out of the device. The first protective cover, the second protective cover and the third protective cover, together with the top plate and the bottom plate, can cover the upper oil cylinder to the lower oil cylinder. The pressure chamber is located inside the second protective cover, and the second protective cover plays the main protective role. By setting the second protective cover between the first protective cover and the third protective cover, the first protective cover and the third protective cover block the second protective cover, so that the second protective cover can block the impact from the splashed metal parts or metal fragments.
