Abstract
The invention discloses a portable well head device and a using method, and belongs to the technical field of geophysical prospecting equipment. Clamping arms are connected with a well seat through clamping arm pin shafts and opening pins, and the clamping arms can rotate around the clamping arm pin shafts. Three supporting legs are connected with corresponding mounting seats below the well seat through supporting leg pin shafts, and the supporting legs swing around the supporting leg pin shafts. The three supporting legs are connected together in series through supporting leg hinges to form a stable triangular support. A dust cover is bound on the inner sides of the supporting legs through thin steel wires or ropes to form an inverted conical cover. The clearance between the upper plane of the well seat of the well head device and the ground is 300mm, and the clearance between the lower edge of the dust cover and the ground is 100mm. The portable well head device and the using method of the portable well head device have the advantages that the elastic clamping arms can guarantee the effective clamping of a drill rod, and the labor intensity for manually holding the drill rod in the well drilling process through a light drilling machine is reduced and relieved. The supporting legs of the triangular frame are stable in supporting and can be folded and bound, and transportation is facilitated. The flexible dust cover can effectively shield rock debris and dust, and does not influence the folding and binding of the supporting legs.
