The technical scheme of the utility model is that: a liquid receiving box of an oilfield wellhead comprises two half-body boxes, wherein each half-body box is a box with a straight edge at one side and a semicircular upper opening at the other side, an outer half-body is arranged in the center of one straight edge side of each half-body box, the lower part of one excircle side of each half-body box is a plane, a transverse half-body is arranged on the plane and is intersected with the outer half-body, a connector is arranged at the bottom of each half-body box, the two half-body boxes are buckled together and are connected with a U-shaped clamp through a section of steel pipe welded on each half-body box, two half-body covers are arranged at the upper parts of the two outer half-body pipes, the two half-body covers are buckled together and are connected with the U-shaped clamp through a section of steel pipe welded on each half-body cover, an inner half-body pipe is arranged on the inner side of each half-body cover, and a sealing strip is arranged between the outer sides of the two inner half-body pipes and the two outer half-body pipes;

the center of the half body cover is provided with a half body hole.

Two joints on the two half body boxes are respectively connected with a hose, and the two hoses are connected to a tee joint.

The upper surface of the half body cover is a conical surface with half small at the top and big at the bottom.

The utility model discloses following beneficial effect has: the butt joint surfaces of the half-body boxes and the butt joint surfaces of the half-body covers are installed in a staggered mode, liquid leakage from the butt joint surfaces is reduced, the half-body boxes which are combined together are buckled on the lower portion of a large flange on the upper portion of a wellhead four-way, two transverse half-body pipe frames which are combined together are fixed in the vertical direction on horizontal pipes on two sides of the oil extraction wellhead four-way, a vertical pipe below the large flange of the two half-body hole four-way is arranged, overflow liquid generated in the process of assembling and disassembling the wellhead flows out and then falls on a conical surface on the upper portion of the half-body cover through the large flange, the overflow liquid flows into the half-body boxes, and is collected through respective connectors and hoses through the tee joints and then is communicated with a ground sewage recovery tank.

Description of the drawings:
